Abstract

Disclosed is a laying arm (27) for an apparatus (1) for helically winding an endless material (3) that is to be wound up, e.g. a continuously extruded tube, preferably made of plastic, onto a rotationally driven winding drum (5). The laying arm (27) transfers the material (3) to be wound up to the winding drum (5) when the laying arm (27) performs an especially substantially linear back-and-forth laying motion. According to the invention, in a contact zone (38) which lies at the end (33) of the laying arm closer to the winding drum and which faces a sidewall flange (11a, 11b) of the winding drum (5), the laying arm (27) comes in direct contact, in particular in direct sliding contact, with said sidewall flange (11a, 11b), especially when the laying arm performs a turning operation. Furthermore, a distance sensor (36), such as a contactor (37), which is located at the end of the laying arm closer to the winding drum, emits a control signal, such as a turning operation-triggering signal, at least when the end (33) of the laying arm closer to the winding drum reaches at least one predefined position. Also, in the area of each contact zone (38), the laying arm comprises an actuating projection (101a, 101b) which, in an inactive position, projects from the respective contact zone in the direction of the back-and-forth laying motion and is mounted on the laying arm (27) so as to be movable, in particular pivotable in such a way that in an open position, the actuating projection (101a, 101b) opens said contact zone (38) to allow for the direct contact.

Description

Laying for a device for winding a strand-like winding material

The invention relates to a laying arm for a device for winding winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic on a rotating winding drum. In the winding material, such as an extruded plastic tube, such as a cable protection tube in which a fiber optic cable can be installed protected, it depends, inter alia, to keep the winding material in a length of several hundred meters in a limited building site in stock, in particular underground to lay over long distances.

It is known to wind the winding material on a winding drum or reel and to transport the wound drum to the construction site. On-site, it can be handled as needed.

For reasons of production economy, the winding operation directly adjoins the production process, in particular the extrusion, of the winding material, so that the extruded plastics material leaves a cooling station without being cut off and is fed to the winding device. The winding process itself is then usually controlled by an operator and optionally manipulated manually.

When using a cable protection tube as a winding material usually a standard winding drum made of wood is used. The cable protection tube wrapped on the wooden winding drum is delivered to construction sites to install it as required. Such cheap, standardized wooden winding drums or other winding drums have proven themselves due to a relatively low price and the possible reusability, especially in use on construction sites. However, the winding drums have rotationally asymmetric axial and radial impacts due to imbalances on the lateral side flanges and on the drum core. Because of the geometric irregularity of the winding drum is a constantly supervised by an operator according to the prior art and manipulated winding of the winding material necessary. In addition to unpredictable differences in geometry of low-price drums, automation has not yet been achieved insofar as the material properties stabilize only after a long curing time in plastic pipes, so that the winding property of the plastic pipe after and during winding can hardly be predicted due to changes in the material properties after extrusion , Such individual hardly predictable winding conditions require an operator with many years of winding experience when monitoring and manipulating the winding material. So far, an at least approximately completely automated winding without manual assistance of an operator, especially at a winding speed of over 100 m per minute could not be achieved.

Winding methods and winding devices are known per se in automation technology, in which electric cables are wound onto geometry-precise rollers. EP 0203046 B1 discloses, for example, a cable winder in which a guide arm, which is directed to the winding roll, has a plurality of arm members, which are connected to one another by means of a plurality of wrist joints. However, it has been found that ideal conditions exist for the cable as well as for the rotationally symmetrical winding drum in the known winding automation processes, which relates to the geometry of the winding drum as well as the material properties of the winding material. Straight wire winders are products of high material quality and uniform and constant material properties. For such windings, a higher cost is operated to provide ideal geometric, unbalance winding coils. It has been found that the known automated winding techniques can not be used successfully when a winding material and a winding drum are used whose material or geometry properties are unpredictable.

It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a laying arm for a device for helical winding a strandförmi- gene winding material, such as a continuously extruded tube, preferably made of plastic on a winding drum, to achieve a higher degree of automation is where a manual intervention by an operator is as far as possible unnecessary.

This object is solved by the features of claim 1. Thereafter, a laying arm for a device for winding winding a strand-shaped winding material (oscillation), such as a continuously extruded tube, preferably made of plastic on a rotary driven winding drum, such as a spool core, provided. The laying arm may preferably be carried and placed by an actuating device, such as a robot, preferably in accordance with a control and / or regulating routine. The laying arm serves to channelize the stranded or wound material to the winding drum and to transfer it for winding, while the laying arm is moved back and forth, in particular substantially transversely to its longitudinal extent and linearly between the axial ends, such as the side wall flanges , The laying arm follows in particular stepwise the axial winding progress of the wound on the winding drum winding material.

The laying arm has a winding drum-side end which is in a contact, in particular rolling contact, with the winding drum or the winding layer already wound thereon for a large part of the entire winding process and on which a contact region facing the respective side flange of the winding drum is formed the laying arm comes into abutting contact with one of the two side flanges, in particular when a turning operation is carried out. The contact can be formed as Anlageschleif- or rolling contact. Furthermore, the device according to the invention has a displacement sensor arranged on the wedge-side end, such as a contactor which emits a control signal, such as a turning operation triggering signal, at least when at least one predefined winding position, at least one triggering position for the turning operation, of the winding drum end is reached. The control signal is sent to an electronic control and / or regulating device, whereby a control for changing a specific control variable of the winding method can be triggered. Preferably, the control and / or regulating device performs a turning operation in which the old winding position is completed and the new winding position on the old winding position is started. In the turning operation, a change of direction of the laying movement of the laying arm is accompanied. According to the invention, the displacement sensor in the region of each abutment region has an actuating projection which protrudes in an unactuated position from the respective abutment region in forward or Herverlegebewegungsrichtung and preferably such movable, in particular pivotally mounted on the laying arm, that the respective actuating projection in its release position the respective contact area for contact with the side wall flange releases. The inventors have found that for the winding technology difficult turning or wall operation, the placement of the winding drum-side end and thus of the laying arm relative to the winding drum is essential in order to realize higher winding speeds of more than 80 m / min can. In particular, the timing at which distance to the side wall flange of the winding drum and when the turning operation is triggered and terminated, is important to realize a faultless completion of the spiral or winding layer and rebuild a solid winding layer base. The contactor, with its actuating projection projecting in the direction of displacement movement, realizes triggering of the control signal prior to reaching the laying movement limiting outer position of the laying arm achieved when the winding drum end of the laying arm contacts the sidewall flange of the winding drum stands. The yielding, in particular rotatable actuating projection allows the contact of the winding drum-side end with the Seitenwandflansch to.

In a further development of the invention, in its release position, the relevant actuating projection is recessed in a vertical view into the laying arm, in particular in a housing structure of the laying arm. The laying arm may comprise a transport space limited in particular by plates, preferably completely closed, in which a pivot axis of the actuating projection is arranged, and the respective actuating projection has disappeared on reaching the side flange wall. Preferably, an actuating outer side of the actuating projection comes into sliding contact with the Seitenflanschwand, in particular the Betätigungsaußenseite the respective Betätigungsvor- jump is substantially flat and level. The actuation outer side of the respective actuation projection is contour-adapted to an outer surface of the abutment region, so that in the release position the actuation outer side lies substantially free of excitation substantially in the plane of the outer surface of the particularly planar abutment region.

In a preferred embodiment of the invention, the actuating projection in its unactuated position (neutral position) is at least half or around a whole winding material thickness and at most two Wickelgutstärken of the respective contact surface in Hinbzw. Herverleebewegungsrichtung ago. In this way, an optimized, preliminary triggering of the control signal can be achieved before the contact area of the laying arm comes into contact with the side wall flange. It is clear that the time period and / or the winding distance between the triggering of the control signal and the contacting of the contact area can be adjusted by triggering the control signal only after exceeding the limit. tion of an adjustable amplitude of movement of the actuating projection is changed from its unimpeded position.

In a further development of the invention, the laying arm has a Wickelgutabgabeöffnung at its winding drum-side end at which the winding material leaves the transport space of the laying arm, to be transferred then in particular guide or contactless of the winding drum. Advantageously, the displacement sensor on the laying arm is arranged closer to a substantially cylindrical drum core of the winding drum than the winding material output at which the winding material leaves the laying arm without guidance, under the exclusive influence of gravity and the internal winding force of the winding material. Preferably, the displacement sensor is arranged in the vertical direction below the winding material delivery, wherein in particular the winding material extends without contact on the components of the displacement sensor over to the winding drum.

In a preferred embodiment of the invention, the laying arm according to the invention comprises a sword-shaped housing, which is preferably formed of two mutually parallel, extending in the longitudinal direction of the laying arm housing plates delimiting a transport space of the laying arm extending from an actuator-side base portion to the winding drum end of the Laying arms extends. The winding material is passed through the transport space extending in the longitudinal direction completely through the laying arm until it reaches a winding material discharge opening. The housing plates in particular have an outer surface, which preferably lies in a vertical plane. The abutment region where the winding drum-side end comes into abutting contact with the side wall flange of the winding drum is formed at an axial end portion of the outer surface of the respective housing plate.

The contact area can be formed by a particular demountable wear plate, in particular of a material of lower friction, such as polyamide. The wear plate is preferably arranged interchangeably at the axial end portion of the two housing plates, in particular screwed.

In a further development of the invention, the contactor has a relative to the laying arm fixedly mounted pivot axis. The pivot axis is rotatably mounted on the housing of the laying arm in the interior of the transport space. The pivot axis remains stationary in each operating position of the actuating projection within the transport space of the laying arm. The pivot axis preferably extends substantially in the vertical direction, so that the respective actuating projection of the contactor is pivoted substantially in a horizontal plane.

In a preferred embodiment of the invention, an additional rotary motion sensor accesses the pivot axis of the contactor, so that in particular after exceeding a predetermined pivoting amplitude of the respective actuating projection, the control signal can be generated and delivered.

To generate the control signal, a pivoting movement transmission mechanism is housed, in particular within the transport space of the laying arm. The pivoting motion transmitting mechanism serves to transmit the pivotal movement of the contactor away from the winding drum end to the base end of the laying arm, preferably without realizing the motion transmission by conversion to an electronic signal. Only at a distance from the winding drum end, an electrical signal generator can be arranged, which is preferably disposed within or optionally outside the transport space of the laying arm, and generates and forwards the control signal based on the transmitted pivoting movement. Preferably, the pivotal movement transmission mechanism is realized by an angular gear which transmits the pivoting movement of the substantially vertically extending, actuating projection-side pivot axis of the contactor to a transmission shaft extending in the longitudinal direction (horizontal direction) of the laying arm.

In a further development of the invention, the actuating projection-side, in particular substantially vertically extending pivot axis of the contactor is biased such, in particular spring-biased that the actuating projection is always forced by its respective release position in the unactuated neutral position. Preferably, the transmission shaft is at least two parts, so that a shaft axis side shaft portion of a pivot axis remote shaft portion is non-destructive disassembled. The division is used for the modular replacement of the entire winding drum-side end of the laying arm to adapt the latter to different strong winding goods can.

In a development of the invention, the contactor has a closed ring structure forming a bow shape. Preferably, the bracket is realized axially symmetrically. In the unactuated position of the contactor, the symmetry axis of the ring structure falls in the unactuated position of the contactor with the longitudinal direction of the laying arm together. The two actuating projections are part of the bow-shaped triangular structure. The triangular structure is preferably realized isosceles, wherein a respective corner of the corner of the triangular bracket shape is rounded off the respective actuating projection. The same legs are arranged at an angle of less than 35 ° to each other, preferably about 30 °.

In an independent or combinable with the above-defined aspect of the invention article of invention is a laying arm for a device for winding winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic on a rotary driven winding drum. The laying arm, which is part of the winding device, can be provided by an actuating device, such as a robot, in order to transfer the winding material to the winding drum in the case of a particularly substantially linear reciprocating movement. For this purpose, the laying arm has a remote from the winding drum arm base, which may be attached to a support of the winding device in particular pivotally mounted in a vertical plane. Between the carrier of the winding device and the actuating device, a rail carriage arrangement may be provided to linearly guide the carrier relative to the actuating device. The arm base may in particular be pivotably articulated to the carrier in a vertical plane. The laying arm extends from the arm base along an elongated structure constituting the arm shape to an end of the laying arm facing the winding drum. The winding drum-side end carries a winding material delivery, which determines a predetermined discharge direction of the winding material away from the laying arm. The Wickelgutabgabe may be designed winding specific and therefore suitable only for a certain winding material size.

According to the invention, the winding drum-side end is coupled to the supporting structure via a mechanical mounting interface which is suitable for detachably detaching or fastening the winding drum-side end from the supporting structure. In a preferred embodiment of the invention, screws are provided, over which the winding drum-side end is releasably secured to the support arm. Other alternative fasteners may also be used to ensure interchangeable docking of the winding drum end to the structure. With the invention is achieved to adapt a winding device quickly and inexpensively to a change of the winding material to be wound. It was found, that in the generic winding technique by means of the winding drum projecting towards the laying arm, the winding drum abutting at the winding drum end and the winding material after leaving the Wickelgutabgabe guideless passes the winding drum, all welngutspezifi see functional components of the laying arm can be arranged at the winding drum end. With the at least one mounting interface for releasably securing the winding drum end, it is possible to use the costly components of the laying arm, such as the arm base and the supporting structure, modularly for a large number of winding material dimensions, with only one for another winding material winding-specific winding drum-side end of the laying arm is replaced. The winding drum-side end preferably carries all winding material-specific functional components, such as the displacement sensor, which will be explained later, the winding material delivery, a Abrollrad and the like.

In a preferred embodiment of the invention, despite possible sensor technology, such as displacement sensors, the mechanical mounting interface is realized without electrical connection. The mounting interface has only mechanical coupling components, wherein Wickeibetrieb- information, which mainly arise at the winding drum end during winding, are only mechanically detected at the winding drum end end and transmitted via the mounting interface in the supporting structure of the laying arm. A particular embodiment of a corresponding, purely mechanical information transmission will be explained with reference to the Wegsensorausführung, which will be described later. The structure may be provided for processing a variety of different sized winding goods with corresponding guide elements that can guide several different winding material sizes between the arm base and the winding material delivery of the laying arm through the transport space of the laying arm. The structure preferably has a plurality of guide wheels that can accommodate a winding material with a diameter between 5 mm and 50 mm.

In a further development of the invention, a displacement sensor, such as a contactor, arranged at least one predefined position of the winding drum end relative to the winding drum a particular kinematic control signal, such as a turning operation trigger signal, preferably by means of a predetermined movement, in particular pivotal movement , emits a releasably mounted on the winding drum end end release part and mechanically transmits over the mounting interface in the structure. If the control signal is triggered and transmitted carry, it can be factory-side, so beyond the exchangeable winding drum end, converted into an electrical signal and fed to a control and / or regulating device, which controls the actuator, for example, such that a turning operation is performed. The displacement sensor is preferably dimensioned in a manner specific to the winding material, wherein a different triggering movement amplitude of the triggering part is preferably set, depending on the winding material thickness, in order to initiate and deliver the kinematic control signal. The larger the winding material thickness, the greater the triggering movement amplitude.

In a further development of the invention, the triggering part is mounted for a pivoting movement about a particular vertical bearing arm fixed bearing arm.

In a further development of the invention, the mounting interface comprises a releasably coupled to the trigger part coupling, such as a dog clutch on which a trigger part-side shaft part is detachably coupled to a support-side shaft part. The trigger part-side shaft part is fixedly mounted rotatably on the winding drum-side end, while the support-side shaft part is rotatably mounted on the supporting structure stationary. Preferably, both shaft parts are mounted horizontally, in the longitudinal direction of the laying arm, wherein the trigger part-side shaft part is connected to the vertical bearing axis of the release part via an angle gear.

In a preferred embodiment of the invention, the laying arm has an electrical signal generator which is coupled to the support-side shaft part and fixed to the supporting structure. The signal generator can be designed as a Hall sensor and serves to convert the pivotal movement of the supporting member side shaft part into an electrical control signal, which is to be transmitted in particular to the control and / or regulating device.

Preferably, the electrical signal generator is designed to generate the electrical control signal only after exceeding a predetermined pivoting movement amplitude of the triggering part. This is to ensure that no false triggering of the control signal is accompanied, which can often occur when the trigger member is not stored with a bias on the winding drum side end, which must overcome the trigger part to be moved .. The predetermined swing amplitude can be set winding specific be. In a further development of the invention, the bearing axis of the release part and / or the shaft parts of the coupling are accommodated within a preferably closed transport space of the laying arm. The majority of the transport space is along the elongated structure. The electrical signal generator can be housed within the transport space of the structure.

The actuating projection may be, for example, a rigid bracket which comes into sliding contact with the side flanges. Preferably, the actuating projections and the vertical pivot axis of the trigger part are made in one piece or at least rigidly attached to each other. Alternatively, however, the actuating projection may also be formed by a rotatably mounted Abrollrad which projects laterally on both sides of the contact area, and comes to form a Abrollkontakts with the side flanges by means of which.

The triggering part can be arranged closer to a substantially cylindrical drum core of the winding drum than the winding material delivery. Furthermore, the release part can be arranged in the vertical direction below the Wickelgutabgabe. In the release position, the respective actuating projection in a vertical viewing in the laying arm, in particular on one side completely retracted, in particular an actuating outer side of the actuating projection comes into sliding contact with the Seitenflanschwand the winding drum and / or has a particular rectilinear operation outside, which on an outer surface of the contact area contour-adapted, so that in the release position, the Betätigungsausßenseite lies in the plane of the outer surface of the contact area. Preferably, in the unactuated position, the actuating projection projects at least by half or all of the winding material thickness and by at most two winding material thicknesses from the respective abutment region in forward or rearward movement direction. In a further development of the invention, the laying arm has two parallel, extending in the longitudinal direction of the laying arm housing plates, in particular extending from the arm base on the structure towards the winding drum end. The housing plates form part of the winding drum-side end, which may have its own outer walls.

The housing plates limit a transport space for the winding material along the structure. The outer surfaces of the housing plates are substantially in a vertical plane.

The abutment region, at which the winding drum-side end comes into contact with the side flange walls of the winding drum, can be formed by, in particular, demountable wear disks, in particular of a material of lesser friction, such as polyamide. Preferably, the friction coefficient of the wear plates is less than that of the housing plate outer surface. Preferably, the wear plates are releasably secured to the winding drum end.

The wear plates are preferably arranged in each case at the axial end portion of the two housing plates, in particular screwed. In a preferred embodiment of the invention, the respective actuating projection of the trigger part is mounted substantially pivotable in a horizontal plane.

In a further development of the invention, the particular vertical bearing axis of the trigger member is biased such that the trigger member is forced into an unactuated middle position in which no or a small bias on the trigger member acts upon deflection of the trigger member depending on the biasing member, such as Spring, raised.

Furthermore, the invention relates to an apparatus for helically winding a proper strangfb ^'shaped winding material, such as a continuously extruded tube, preferably of plastic on a rotationally driven winding drum, said developing device comprising the laying arm according to the invention.

Furthermore, the invention relates to a modular system for a laying arm of an apparatus for helically winding a proper strangfb ^'shaped winding material, such as a continuously extruded tube, preferably of plastic on a rotationally driven winding drum. The modular system has a laying arm according to the invention with at least two interchangeable winding drum side ends in order to process at least two different winding materials by exchanging the winding drum side ends and a modular support structure of the laying arm system.

It is clear that the device according to the invention and the method according to the invention are designed in accordance with the devices and methods described in the filed German patent applications (10 2013 002 023.9, 10 2013 002 022.0, 10 2013 002 017.4, 10 2013 002 019.0 and 10 2013 002 020.4) could be.

Preferably, the displacement and displacement movement of the laying arm is limited by the side wall flanges of the winding drum. The direction of the back and forth laying movement can be predominantly parallel and / or slightly inclined to the axial direction. The winding device may comprise an active laying arm adjusting device for vertically positioning the laying arm relative to the winding drum, which in particular can lift and lower the laying arm only in the vertical direction. The displacement sensor can also be used to detect at least one predetermined position of the laying arm, wherein upon reaching the at least one position preferably via a control and / or regulation cause the Verlegearmstelleinrichtung, the laying arm by about at least half a thickness of the winding material, preferably at least about a winding material, and to remove at most a twofold of the winding material thickness from the winding drum or from the winding already laid thereon away, in particular to lift in an exclusive vertical movement. The vertical lifting of the laying arm, in particular of the winding drum side end, for the change of direction of the forward and herverleebewegung be limited insofar as the winding drum side end to be taken after laying the first winding loop of the new winding position of the winding loop in a substantially axial Verlegebewegungs- direction, to drive the laying arm for the to and fro laying movement.

In particular, the laying arm adjusting device provides exclusively vertical lifting movement to initiate the directional change of the reciprocating motion, and subsequently, after the first winding loop of the new winding layer has come in lateral engagement with the raised winding drum end of the laying arm, the laying arm adjusting device returns the laying arm as far back settles until the winding current melseitige end in particular either rolling or sliding comes in a radial contact to the completed winding position.

In a preferred embodiment of the invention, the displacement sensor is arranged on a winding drum-side end of the laying arm. Preferably, the displacement sensor is a contactor, which then emits an electrical control signal, in particular to a control and / or regulation or directly to the Verlegearmstelleinrichtung when the laying arm, in particular its winding drum side end, which reaches at least one predefined position. Preferably, the predefined position corresponds to the end of the forward and herverleebewegung. Preferably, the at least one predefined position when contacting the contactor is defined with an inner side of a side flange of the winding drum. Alternatively, the end of the reciprocating motion may be accompanied without structural contact with the side flange of the winding drum, for example, by achieving a certain minimum separation of the winding drum end from the side flange, which may be, for example, between about two times the winding material thickness or about one winding material thickness or less.

In a preferred embodiment of the invention, the displacement sensor has a freely rotatably mounted wheel, the bearing axis of rotation in particular in the axial direction of the side flange of the winding drum is pivotally away, whereby the triggering of the electrical control signal can be achieved. The wheel of the displacement sensor is rotatably mounted in such a way that it can roll in contact with the rotating side flange and can be pivoted in the axial direction from a passive position to an active position in a further displacement of the laying arm, in which the electrical control signal optionally via a controller and / / or regulation of Verlegerearmstelleinrichtung is communicated.

Preferably, the freely rotatably mounted wheel of the displacement sensor is located at the winding drum end of the laying arm in the region of a 12 o'clock position with respect to the winding drum, in particular under the influence of the weight of the laying arm on the winding drum or on an already laid winding position substantially tangentially.

In a further development of the invention, the winding drum-side end of the laying arm is designed to stand in the forth and Herverlegebewegung, in particular at least when reaching the predetermined position, in a continuous lateral contact with a free lateral side of the last laid on the winding drum winding loop. The winding drum-side end loses contact with the winding position upon removal from the winding and remains in the non-contact position until the winding drum side end is formed by forming the lateral contact with the free lateral side of the new, last-positioned winding loop for starting the forward and backward movement movement Change of direction is taken.

In a preferred embodiment of the invention, the Verlegearmstelleinrichtung has a pivot bearing for pivoting a winding drum-side end of the laying arm, in particular only in a vertical plane. The pivot bearing allows a relative pivoting movement between the laying bar of the laying arm and the laying arm base, which in turn is movably mounted on the carrier of the winding apparatus via the laying arm, in particular linearly substantially along the axial direction of the winding drum. On the carrier handles the handling device, such as the positioning robot, which is responsible for the vertical movement for lifting the pivot axis of the pivot bearing. The handling device can also be responsible for moving the carrier in the direction of the back and forth movement, so that the carrier can follow the laying arm leading by the axial winding increase.

Preferably, the Verlegearmstelleinrichtung has a lifter for particular linear lifting and / or lowering the pivot axis of the pivot bearing, wherein the lifter can be realized in a component union by the handling device, such as the positioning robot. Furthermore, the laying arm adjusting device may have a damper for damping the pivoting movement.

In a further development of the invention, the pivot bearing can rest the winding drum-side end of the laying arm on the winding drum or on an already laid winding position under the influence of the weight. The Verlegearmstelleinrichtung, in particular the pivot bearing, may include a support stop in particular as a lower pivot limit for limiting the vertical mobility of the laying arm towards the winding drum. In the resting of the winding drum-side end of the winding drum or on the last-placed winding position of the support stop is positioned so that a free, in particular only damped, approximate movement of the winding drum end towards the winding drum of at most one winding material, preferably at most a quarter of the winding material is allowed , Alternatively or additionally, the support stop may serve to guide the laying arm, in particular the laying load, for removal. away from the winding drum end away from the winding drum or away from the winding position away.

In a preferred embodiment of the invention, the winding device according to the invention comprises a laying arm, which leads the laying arm in a particular direction depending on the axial position along the laying path rotatable laying direction relative to the carrier in particular linear, and a restoring or biasing device relative to the displacement of the laying arm in the laying direction to the carrier the restoring arm informs a restoring or biasing force to urge the laying arm laterally, substantially axially against a last laid on the winding drum winding loop. The laying arm support may comprise a carriage-rail arrangement, according to which the laying arm is guided linearly in the laying direction relative to the carrier. The axial direction is defined by the axis of rotation of the winding drum. The rotatable laying direction may be parallel to the axial direction, in particular depending on the position of the laying arm along the laying path and / or inclined to produce a free running angle of the laying arm, in particular less than 20 ° with respect to the horizontal radial extent of the side flange of the winding drum. The carriage is designed Verlegearmseitig, the rail is realized carrier side. A handling device, such as a positioning robot, advances the carrier, following the laying arm, and serves to reduce the increasing displacement of the laying arm, caused by the axial growth of the winding layer and always leading past the advancing carrier. The restoring force serves to constantly press the laying arm against the last-laid winding loop and in particular to maintain a bias against the winding loop and thus the winding loop contact when the handling device tracks the carrier following the laying arm. The carrier may only be tracked so far that continues to remain a sufficient biasing force on the laying arm against the last-placed winding loop. The higher the deflection of the laying arm relative to the carrier, the stronger the restoring force of the rear part device. With this aspect of the invention, an optimally compact, tight arrangement of winding loop to winding loop is realized.

In a preferred embodiment of the invention, the winding drum-side end is mounted such that at least a part, preferably for the entirety of the back and forth laying movement in particular up to the laying direction change the winding drum end to form a substantially axial lateral contact with a free lateral side of the last the winding drum wound winding loop through the axially extending winding position along the laying path is driven. In this way, a correctively flexible behavior of the laying arm required for the automation is realized which already comes very close to the manual manipulation of an experienced operator, whereby in particular geometric imbalances of the winding drum or the winding do not impair an automated winding process. The winding-drum-side end is preferably formed by a wheel mounted so as to be freely rotatable on the laying arm, at least part of the side area projecting beyond the laying arm so as to be able to come into contact with the still free lateral side of the last wound winding loop, and this in the direction of rotation is only driven in rotation by the winding drum or by the winding material already lying on the winding drum. In the laying direction, the wheel is taken along by the constantly axially growing winding position along the laying path and moved axially. At the same time, the wheel rolls on the winding drum or the already completely laid winding position, at least under the influence of the weight of the laying arm.

Furthermore, a preferred embodiment of the invention relates to an adjusting or releasing device which, at least during the laying movement near the side flange of the winding drum, inclines the laying arm away from the one side flange in a "positive" angle of attack for the horizontal radial extent of the one side flange and the laying arm in the course the back and forth laying movement towards the opposite side flange in a "negative" angle of attack from the other side flange inclined inclined. The actuating device is preferably formed by the handling device, such as the positioning robot, which, in order to operate the desired pivoting movement about the winding loop contact, provides the carrier. The pivot axis of the pivoting movement is preferably in the region of the winding drum-side end of the laying arm. The pivot point can migrate along the forward and Herverlegewegs. It is sufficient to set a clearance angle of 1 ° to 20 °. Corresponding to the free-setting angle, the rotatable laying direction of the laying arm defined by the laying arm position is also inclined with respect to the axial direction, whereby the angle of inclination at the axial ends of the reciprocating movement is correspondingly greatest and in the course of the to and fro laying movement, such as Free-fall angle, decreases and disappears about halfway laying and then gradually increases in particular gradually.

In a preferred embodiment of the invention, a winding material brake is arranged on the laying arm, which is a braking force to the winding material before reaching the winding drum communicates to bias the winding material to train. The braking force can be adjusted according to the operation in particular by a control and / or regulation.

Furthermore, the invention relates to a method for winding the strand-like winding material, such as the continuously extruded tube, preferably made of plastic on the winding drum. The winding material is transferred to the rotating winding drum via the laying arm mounted for the transferring movement. At least one predetermined position of the laying arm is predetermined for a change of direction of the forward and herverleebewegung, wherein the achievement of at least one position is determined by means of sensors. Upon reaching the at least one predefined position of the laying arm, the laying arm is preferably controlled and / or regulated by about at least half a thickness of the winding material, preferably by about one winding material thickness, and at most about twice the winding material thickness by the winding drum or by the already placed on winding position away, in particular raised.

Preferably, the predetermined position for changing direction of the back and forth laying movement is achieved when the winding drum end of the laying arm, which is in a particular displacement of the laying arm along the laying path constant contact with the winding drum and / or the already placed winding position, an inside of a Side flange of the winding drum contacted or at the latest when it is at a distance of at most twice the winding material, preferably from about a winding material, to the inside of the respective side flange.

Furthermore, the invention may relate to a winding device having the laying arm according to the invention. The device preferably comprises a carrier, on which various functional parts of the winding device can be attached, such as the support arm movably mounted on the support according to the invention with the winding material receiving for accepting the winding material leaving in particular an extruding station and the winding drum end on which the winding material of the rotating Winding drum to be handed over in a particularly linear reciprocating movement of the laying arm along a rotation axis of the winding drum wound up. The carrier receives the winding material on a support receptacle, which may be formed for example by a cross-shaped roller arrangement. The displacement movement of the laying arm is preferably purely translatory for each winding position in a horizontal plane. Since the winding layers lie one above the other, a separate linear approach is required for each winding layer. and Herverlegeweg each offset in the vertical direction by a winding material strength realized, in particular, the forward and Herverlegeweg is not rigidly predetermined according to a fixed control routine, but rather flexibly depending on the individual Wibkelungsverlegeverlauf sets. For this purpose, the laying arm is mounted on the carrier in such a way that the winding drum-side end of the laying arm follows the axially expanding winding position to form a lateral contact with a free lateral side of the wound winding wound on the winding drum, at least in one part of the particularly linear reciprocating motion. According to the invention, the winding device does not provide the winding drum end according to a predefined control routine, but provides for the winding gain yielding freedom of movement for the laying arm, whereby geometric imbalances and changes in geometry during the winding process can be compensated. In contrast to the prior art, in which rigid control actuation systems implicitly require an ideal geometric winding drum, the winding device according to the invention achieves automation even when unpredictable geometry changes and geometric properties have to be considered. The winding drum-side end of the laying arm contacted constantly the last-placed winding loop and according to the invention taken from this, preferably by the laying arm an elastic force acting on the winding drum end against the last laid winding loop, so even with imbalances and axial or radial blows the lateral contact between the last laid winding loop and the winding drum side end is not lost in particular due to inertia.

It should be understood that the winding drum end may also maintain radial contact with a drum core of the winding drum or with the already completed winding position. The required radial contact forces are preferably realized due to the influence of the weight of the laying arm with a corresponding pivot bearing for the laying arm on the support.

In a preferred embodiment of the invention, the laying arm is mounted on the carrier in such a way that the winding drum end temporarily loses contact with the winding for a change in the direction of the reciprocating movement, in particular in the formation of a next winding position, and so long without contact Winding remains until the winding drum-side end to form the renewed lateral contact from the free lateral side of the newly forming, first winding loop in axial Verlegebewegungs- direction is taken. Only at the two axial ends of the laying movement path is the permanent contact between the winding drum-side end and the winding position and / or the drum core canceled.

In a preferred embodiment of the invention, the winding drum-side end of the axial extension of the winding position compliant follows in particular continuously, by an elastic restoring or biasing force of a restoring or biasing means presses the winding drum end against the lateral side of the last laid winding loop. In this case, the elastic restoring force is directed substantially in the axial direction, in particular parallel to the axis of rotation of the winding drum, that the substantially exclusively lateral forces are introduced from the winding drum side end in the last-placed winding loop, so that the last-laid winding loop against the adjacent winding loop laterally , is axially biased. The elastic restoring force or axial prestressing against the last-laid winding loop is preferably realized by the restoring device, which may have, for example, a pneumatic actuator or another spring system. The return device can act between the carrier and the carrier arm movably mounted to the carrier.

In a further development of the invention, the winding drum-side end has a freely rotatably mounted on the laying arm engaging wheel. The bearing of the engagement wheel should be free of any other drive forces, but should only be placed in a rotational movement when it comes into contact with the winding drum or laterally with an already laid winding position. The sprocket may have a verlegearmbezogen fixed axis of rotation, which may be arranged substantially parallel or slightly inclined to the axis of rotation of the winding drum. In order to avoid a sliding contact between the laying arm and a side flange of the winding drum, the laying arm can be inclined in accordance with an angle of attack to the radially extending inside of the side flange. In this case, the rotation axis of the engagement wheel does not coincide with the rotation axis of the winding drum, but is inclined by a few degrees.

In a preferred embodiment of the invention, the engagement wheel has a circumferential cylindrical rolling surface, which runs on the cylindrical drum core of the winding drum or on an already laid on the winding drum winding position. In this case, the rolling surface of the sprocket presses under the influence of the self-weight force of the vertical direction pivotally mounted on the carrier laying arm on the drum core or the winding position.

Preferably, the engagement wheel protrudes in sections over the winding drum end in such a way that a blank, freely accessible, lateral side region is formed, which is preferably a smooth flat surface situated in a vertical plane in the case of a disk-shaped engagement wheel. On the side region, the engagement wheel is pressed under the influence of the axial restoring force against the free radial lateral side of the winding loop last laid. The freely accessible side region of the engagement wheel can be dimensioned such that the lateral side of the winding material engages exclusively with the side region to form the lateral contact. The tread of the engagement wheel comes into rolling engagement with the radially underlying winding layer or drum core.

In a preferred embodiment of the invention, the laying arm is mounted on the carrier such that the winding drum end extends along a linear engagement path on the outer circumference of the winding drum core or on a winding position last laid on the winding drum in accordance with the gradually increasing axial extension of the winding layer to be wound around the winding material thickness gradually crazy. The engagement path may preferably be substantially at a 12 o'clock circumferential position to most effectively utilize the weight forces of the dead weight of the laying arm. Preferably, the laying arm lies tangentially on the engagement path under the influence of its own weight.

In a preferred embodiment of the invention, the laying arm has the shape of a sword. The shaft of the sword is the carrier side, while the tip of the sword protrudes towards the winding drum. The tip of the sword is in constant contact with the winding drum or already laid winding position, at least during the back and forth laying movement.

The laying arm may be formed by two substantially parallel plates whose longitudinal direction extends towards the winding drum and whose width direction is aligned in the vertical direction. The parallel plates can form a guide space or gap between them, in which the winding material is guided within the laying arm towards the winding drum end. The leadership of the winding material within the laying arm can preferably by at least one particular free-running role and / or by at least a particular freely running roller pair may be formed. The roller and / or the pair of rollers may be rotatably mounted on the plates.

Preferably, a pair of delivery rollers is preferably freely rotatably mounted on the winding drum end over which the winding material leaves the laying arm to be wound in the course of the winding drum without influencing a further mechanical structure such as the sprocket.

In a further development of the invention, the carrier-laying arm has a carriage rail arrangement through which the laying arm is guided in particular substantially parallel to a rotation axis of the winding drum relative to the carrier. The rails and the laying arm of the carriages are preferably fastened to the carrier, wherein in particular the rear-part device acts between the carriage and the rail. The return device serves to generate an elastic spring force in order to bias the winding drum-side end against the last-laid winding loop.

In a preferred embodiment of the invention, the winding device according to the invention comprises a laying arm, which leads the laying arm in a particular direction depending on the axial position along the laying path rotatable laying direction relative to the carrier in particular linear, and a restoring or biasing device relative to the displacement of the laying arm in the laying direction to the carrier the restoring arm informs a restoring or biasing force to urge the laying arm laterally, substantially axially against a last laid on the winding drum winding loop. The laying arm support may comprise a carriage-rail arrangement, according to which the laying arm is guided linearly in the laying direction relative to the carrier. The axial direction is defined by the axis of rotation of the winding drum. The rotatable laying direction may be parallel to the axial direction, in particular depending on the position of the laying arm along the laying path and / or inclined to produce a free running angle of the laying arm, in particular less than 20 ° with respect to the horizontal radial extent of the side flange of the winding drum. The carriage is designed Verlegearmseitig, the rail is realized carrier side. A handling device, such as a positioning robot, advances the carrier, following the laying arm, and serves to reduce the increasing displacement of the laying arm, caused by the axial growth of the winding layer and always leading past the advancing carrier. The restoring force serves to constantly push the laying arm against the last-placed winding loop and in particular then maintain a bias against the winding loop and thus the winding loop contact when the handling device tracks the carrier following the laying arm. The carrier may only be tracked so far that continues to remain a sufficient biasing force on the laying arm against the last-placed winding loop. The higher the deflection of the laying arm relative to the carrier, the stronger the restoring force of the return device acts. With this aspect of the invention, an optimally compact, tight arrangement of winding loop to winding loop is realized.

Furthermore, a preferred embodiment of the invention relates to an adjusting or releasing device which, at least during the laying movement near the side flange of the winding drum, inclines the laying arm away from the one side flange in a "positive" angle of attack for the horizontal radial extent of the one side flange and the laying arm in the course the back and Herverlegebewegung towards the opposite side flange in a "negative" angle of attack from the other side flange inclined inclined. The actuating device is preferably formed by the handling device, such as the positioning robot, which, in order to operate the desired pivoting movement about the winding loop contact, provides the carrier. The pivot axis of the pivoting movement is preferably in the region of the winding drum-side end of the laying arm. The pivot point can migrate along the forward and Herverlegewegs. It is sufficient to set a clearance angle of 1 ° to 20 °. Corresponding to the free-setting angle, the rotatable laying direction of the laying arm defined by the laying arm position is also inclined with respect to the axial direction, whereby the angle of inclination at the axial ends of the reciprocating movement is correspondingly greatest and in the course of the to and fro laying movement, such as Free-fall angle, decreases and disappears about halfway laying and then gradually increases in particular gradually.

In a preferred embodiment of the invention, a Verlegearmstelleinrichtung is provided for the vertical positioning of the laying arm relative to the winding drum for the proper operation of the laying arm especially in a change of direction of back and forth laying. The Verlegearmstelleinrichtung cooperates with a displacement sensor for detecting at least a predetermined position of the laying arm along the laying path, wherein optionally the displacement sensor causes upon reaching the at least one predefined position, the Verlegearmstelleinrichtung, the laying arm by at least about half the thickness of the winding material, preferably by about a winding material or by more than one winding material thickness, and at most two times the winding material thickness of the winding material drum away or lift away from the already applied winding position. The laying gear adjusting device can have a vertical pivot bearing in particular for the laying arm, wherein a pivot axis of the laying arm is arranged on the carrier side. The pivot bearing can be realized, for example, in that a winding drum-side laying arm blade is pivotable relative to the carrier-side laying arm base in the vertical direction. Furthermore, the laying arm adjustment device can have a lift for, in particular, vertical lifting of the pivot axis in the vertical direction, wherein the lift is formed, for example, by the handling device, such as the setting robot, which accesses the carrier in order to lift the carrier together with the laying arm pivot axis vertically linearly. In order to take the pivotable winding drum-side end when lifting, the pivot bearing has an abutment stop, which limits a lowering of the winding drum-side end of the laying arm. The pivot bearing allows on the one hand a flexible contact sequence of the winding drum side end of the already placed winding layer and thus a free contour following the already laid winding layer and its radial imbalances, on the other hand limits the investment stop lowering the winding drum end from the support to the winding position by at most half Wickelungsgutstärke , the winding drum end should come between two adjacent adjacent winding loops.

In a preferred embodiment of the invention, a winding material brake is arranged on the laying arm, which informs the winding material before reaching the winding drum of a braking force to bias the winding material to train. The braking force can be adjusted according to the operation in particular by a control and / or regulation.

Furthermore, the invention relates to a method. Thereafter, a strand-shaped winding material, such as a continuously extruded tube, preferably wound from plastic onto a winding drum by the winding material of the rotating winding drum is transferred via a mounted for a Her and laying movement laying arm. In addition, a winding drum side end of the laying arm is maintained in a constant lateral contact with a free lateral side of the wound on the winding drum windings of the winding material at least in a part of the particular linear back and forth laying movement, so that the winding drum side end of the axially expanding winding position follows.

It is clear that the method according to the invention can be designed in accordance with the operating function of the winding device according to the invention. Further preferred embodiments are specified in the subclaims.

Further features, features and advantages of the invention will be elucidated by the following description of a preferred embodiment of the invention with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of an apparatus for winding a continuously extruded plastic tube onto a winding drum in an initial operating condition where a first Winding layer is deposited on the winding drum; a perspective view of the winding device according to Figure 1 shortly before the operating state of a winding layer direction change; a detailed perspective view of the engagement of a winding drum side end of a laying arm on the winding and the winding drum according to the operating state of Figure 2a; a perspective view of the winding device during the operating state of the winding layer direction change; a detailed perspective view of the winding drum-side end of the laying arm according to the operating state of Figure 3 a; a perspective view of the winding device in the operating condition after the winding layer direction change; a detailed perspective view of the winding drum-side end of the laying arm according to the operating state of Figure 4a; a perspective view of the winding device with axes of movement of a support of the winding device and the laying arm;

Figure 14; and FIG. 18 shows a perspective view of movement organs of the laying arm according to the invention which are for the most part accommodated in the transport space of the laying arm.

In Figure 1, the winding device according to the invention is generally provided with the reference numeral 1. The winding device 1 serves to wind a continuously extruded from an extrusion, not shown, plastic tube 3, such as a so-called cable protection tube on a winding drum 5, wherein a uniform possible winding without space between the individual winding loops 17 and with a substantially constant winding pitch of a plastic pipe width per Rotation is to be achieved, as shown for example in Figures 1 to 4b.

The winding drum 5 comprises a substantially cylindrical drum core 7, at the two axial ends in each case a lateral, extending in the radial direction side flange I Ia, I Ib is attached. Concentric with the rotational symmetry of the winding drum 5, a rotation axis 13 of the winding drum 5 is fixedly mounted (relative to a reference bottom B on which the winding device 1 stands) about which the winding drum 5 rotates to perform the winding operation. The axis of rotation 13 defines an axial direction, to which reference will also be made in the following to define movements of moving components of the winding device 1.

For economic reasons, the standardized winding drum 5 is often made of wood, wherein the drum core 7 and the side flanges I Ia, I Ib can deviate slightly, but not negligibly from an ideal symmetrical shape. The cylindrical drum core 7 may have radial impacts, while the side flanges I Ia, I Ib can form Axialunwuchten. Also winding drums 5 made of other material, such as plastic, often deviate from an ideal symmetric rotational shape at random or due to production.

As shown in Figure 1, the extruded plastic tube 3 is already wound in an initial winding position by more than the axial half of the winding drum 5 to the drum core 7. In the following, the winding loop, which has just been applied last to the drum core 7, shall be provided with the reference numeral 17. The winding loop 17 has, until the next winding loop is completely encircling and has applied laterally, a circumferential portion free axial lateral side 18, to which reference is made in the following mainly at an approximately 12 o'clock circumferential location (contact with the engagement wheel 43) shall be. The plastic pipe 3 is extruded continuously cylindrical along its extension and may have an outer diameter of 5 mm to 30 mm or 40 mm. The thickness of the plastic pipe 3 may be about 10% to 60% of the outer pipe radius. The plastic pipe 3 is continuously formed in an extrusion station (not shown) and passes through a cooling line (water bath) in the winding device 1, which may be preceded by a plastic pipe (3) buffer system (not shown), through the different conveying speeds of Plastic tube 3 to be compensated in the longitudinal direction during the extrusion process and during winding. The buffer system, not shown, may for example be designed as a vertical pendulum, which can compensate for the vertical displacement of a diverter wheel too little / too high speed of the winding device 1 relative to the extruding device by the guide wheel occupies a higher / lower vertical position. In this way, a buffer line for the extruded plastic pipe (3) can be achieved for a continuous manufacturing process before it enters the winding device 1.

The winding device 1 according to the invention essentially consists of four main components, namely a carrier 23, a rear part device 61, a positioning robot 71, which is indicated only in FIG. 5, and a laying arm 27 according to the invention.

The laying arm 27 according to the invention has the shape such as a chainsaw with a Verlegerearmbasis 28 (actuator / motor base) and a laying blade 29, which extends from the Verlegerearmbasis 28 substantially in the horizontal direction to the winding drum 5 and these touches directly or indirectly. The laying arm base 28 has on its side facing away from the winding drum 5 a receptacle 21 (FIGS. 6, 9 and 10) for accepting the plastic pipe 3 which in particular leaves an extrusion station continuously. The receptacle 21 comprises pairs of rollers 25 arranged in a star shape which delimit a threading opening to ensure a horizontally and vertically guided threading of the plastic tube 3 in the laying arm 27. The laying arm base 28 is mainly formed by a profile support 57 which is composed of a plurality of mutually joined support plates. Functional components of the winding device 1, such as a microcomputer, actuators, etc., can be attached to the support plates.

The carrier 23 movably holds the laying arm 27 and in the illustrated embodiment has a rail 51 to which a gripping arm of the setting robot 71 is attached. The rail 51 cooperates with a carriage 53 of the laying arm base 28 such that the laying arm 27 can be reciprocated along the linear carriage path.

The laying blade 29 extends predominantly in a horizontal direction, approximately perpendicular to the axial direction 13 of the Verlegerearmbasis 28 away to the winding drum 5, wherein the laying arm 27 is dimensioned so that in the longitudinal direction over the drum core 7 (to about in the axial center) protrudes (considered in lifting direction A).

The laying blade 29 has two vertical, mutually parallel guide and holding plates 31a, 31b. Between the two holding and guide plates 31a, 31b, which have a substantially constant vertical width in their essentially horizontal extension direction, a guide gap is formed for forming a transport space 32 for the plastic tube 3. In order that the plastic tube 3 can slide safely from the receptacle 21 along the laying arm 27 between the holding and guide plates 31a, 31b, guide rollers can be rotatably mounted in the guide gap on the holding and guiding plates 31a, 31b and a guide channel defined by the transport space 32 through.

At a winding drum-side end 33 of the laying arm 27, a winding material delivery 34, in particular in the form of a pair of delivery rollers 35 with horizontal axes of rotation is still stored in the transport space 34, which ensure guided delivery of the plastic pipe 3 from the winding drum-side end 33 of the laying arm 27 to the winding drum 5. Between the laying arm base 28 and the winding drum end 33 extends an arm or striven-shaped support structure 30. The structure 30 may be bounded laterally by vertically arranged plates and limit the transport space 32. On the support 30, a plurality of guide rollers for carrying out the winding material are rotatably mounted.

On a top side of the winding drum-side end 33, a displacement sensor 36 is positioned in a first embodiment of a contactor 37. The contactor 37 comprises a freely rotatably mounted contact wheel whose axis of rotation is arranged vertically. Another known from the prior art displacement sensor can be used. The contact wheel has a passive operating state during the laying movement W of the laying arm 27 between the left side flange 11b and the opposite right side flange 11a, in which the axis of rotation lies in a guide gap of the laying edge 29. Preferably, once the contact wheel of the contactor 37 in engagement with the radial inside 41st the contact wheel, in particular its vertical axis of rotation, deflected in the axial direction, because the contact wheel on the winding drum side end 33 of the laying arm 27 projects axially in both axial directions and pivotally mounted on the laying arm 27 for axial deflection is. During axial deflection of the contact wheel, the contactor 37 outputs an electrical contact signal to a control and / or regulating device (not shown), which processes the contact signal for the further winding operation of the winding device 1. The triggering of the electrical contact signal can be initiated and transmitted immediately after the movement of the contact wheel from its non-active center position or with a path-dependent delay after reaching a predetermined pivoting amplitude.

At the winding drum-side end 33 of the laying arm 27, a contact region 38 is formed, on which the winding drum-side end 33 of the laying arm can come into sliding contact with the side flange wall 11a, 1b of the winding drum 5. For this, the pivot bearing 39 of the displacement sensor 34 is designed such that the contact wheel of the contactor 37 is pivoted away at least to the level of the outside of the respective abutment portion 38, so that the actuating projection of the contact wheel is completely sunk in the lateral direction and the respective abutment portion 38 is released , An alternative displacement sensor implementation is described below.

On the underside of the winding drum-side end 33 opposite the upper side, an engagement wheel 43 is mounted so as to be freely rotatably mounted on the laying arm 27 whose axis of rotation lies substantially horizontally parallel to the axis of rotation 13 of the winding drum 5. The running surface of the engagement wheel 43 is in direct rolling contact with the driven drum core 7 or an already placed winding position. A freely accessible side region of the engagement gear 43 abuts when winding with a predominantly axial pressure biasing contact on the axial lateral side 18 of the winding loop 17 last laid.

The axial width of the tread of the engagement wheel 43 is dimensioned such that it is greater than half the outer diameter of the plastic tube 3, but smaller than the outer diameter of the plastic tube 3.

The laying arm 27 is mounted so as to be vertically pivotable via a carrier-side (23) pivot bearing, which is not illustrated in any more detail, wherein a carrier-side pivot axis S is horizontal, at least as a function of the laying position parallel to the axis of rotation 13 of the pivoting position. ckeltrommel 5 runs. To control the pivoting movement of the laying arm 27 in a vertical plane, a damping unit 45 is provided, which is fastened on the one hand to the carrier 23 and on the other hand to a projection 47 on the upper side of the laying bar 29. The damping unit 45 ensures a damped pivoting movement of the laying arm 27 about the carrier-side pivot axis S. A pivot stop (not shown) is provided, which limits pivoting of the laying arm 27 in the vertical plane down to the winding drum 5. The pivotal stop ensures that the engagement gear 43 does not press between two already laid winding loops and completely penetrates between them, in order to avoid contact engagement of the engagement wheel 43 with an underlying complete winding position. The pivoting mobility of the laying arm 27 and the position of the pivot stop are set relative to the laying arm 27 such that the engagement wheel 43 is in rolling contact in rolling contact with the cylindrical drum core 7 or the last laid winding position. However, the pivot stop stops a lowering of the engagement roller 43 from at most half the thickness of the plastic tube 3, so that a rolling contact on the last completely laid winding position is prevented.

The support 23 is displaceable relative to the fixed axis of rotation 13 or the stationary reference base B of a production hall by one of the positioning robot 71, which is fixedly mounted on the reference bottom B, the carrier 23 engages, holds and positioned according to the winding process control.

In Figure 5, the axes of movement of the positioning robot 71 are partially shown, wherein the positioning robot 71, the carrier 23 in the horizontal direction, which corresponds to the axial direction (rotation axis 13) and substantially the laying direction V, and in lift direction A can move linearly and wherein the positioning robot 71 the Carrier 23 can pivot about the lateral contact K (about the axis of rotation D).

The point of engagement of the engagement wheel 43 with the drum core 7 or the winding position already laid forms an actuating point at which the laying arm 27 is axially displaced axially relative to the carrier 23 by the axial increase of the winding position 15. This may be referred to as a flexibly responding following movement of the laying arm 27, which immediately follows the continuous axial laying of the winding loops 17 and the axial growth of the winding layer 15. A vertical pivoting movement about the pivot axis S due to the abutment of the engagement wheel 43 on the winding drum 5 and a radial growth of the winding layers realizes a follow-up of the bearing arm 23 mounted on the initially stationary support 23. The follow-on movement of the laying arm 27 and the readjusting movement of the support 23 are indicated by the double arrows V, A in FIG.

The positioning robot 71 holds the carrier 23 by means of the rail 51, which cooperates with the carriage 53, which is formed by a base plate 55 and a profile carrier 57 extending downwardly therefrom. The carriage 53 and the rail 51 form a translatory bearing, the translational laying direction V is set substantially or approximately parallel to the horizontal axial direction (rotation axis 13). The carriage (53) rails (51) - arrangement gives the laying arm 27 a freedom of movement relative to the carrier 23 only in the laying direction V, so that the carriage 53 only in the laying direction V relative to the positioning robot 71, in particular its gripper arm (not shown) , can be relocated.

The rail (51) sled (53) arrangement provides axial compliance for the laying arm 27. The axial compliance is provided by the degree of freedom of movement in the laying direction V. In order that the engagement wheel 43 does not lose contact with the lateral side of the last-positioned winding loop 17 during the laying process between the two side flanges 11a, 11b, a restoring or pretensioning device 61 acts between the carriage 53 and the rail 51 and provides an elastic return or biasing force generated when the transfer arm 27 from a predefined neutral position relative to the carrier 23, in which no restoring forces of the restoring device 61 between the rail 51 and the carriage 53 act in the laying direction V, driven by the axial expansion of the winding layer 15, is deflected. The amount of the restoring force is greater, the greater the deflection of the laying arm 27 from the neutral position. The return device 61 is formed by a pair of pneumatic actuators 63, 65, the details of which are indicated in FIGS. 7 to 10. A pneumatic actuator 65 or 63 is active for generating the restoring force only in one of the laying directions V (for example, from the side flange 11a to the side flange 11b), while the other pneumatic actuator 65 or 63 in the opposite laying direction V (of FIG Side flange I Ib to the side flange I Ia) is active.

If the laying arm 27 is displaced by the periodic, horizontal laying of the winding loop 17 in the laying direction V, the end 33 of the laying arm 27 together with the slide 53 displaces in the linear laying direction V relative to the rail 51, which in the meantime remains uninhibited. flows stationary provisionally in their position until it is adjusted, for example, when exceeding a deflection threshold of the carriage 53 by the positioning robot 71, which reduces the restoring force of the return device. Due to the relative movement between the carriage 53 and the rail 51, the pneumatic actuator 63 or 65 (depending on the axial laying direction) pneumatically clamped, so that in the pneumatic actuator 63, 65, the pneumatically elastic restoring force is generated, which via the carriage 53 to the laying arm 27 is communicated and finally the sprocket 43 biases axially against the free lateral side 18 of the last wound winding loop 17. The axial return bias ensures that all the winding loops 17 are placed close together in the axial direction to achieve the desired uniform winding sequence, and can be flexibly adapted to geometrical and material-specific anomalies.

It is clear that the pneumatic actuator 63, 65 can also generate independently of the laying of the laying arm 27 an actively controlled, pneumatic restoring force, for example by the pneumatic actuator via a control and / or regulating device, not shown, for example, depending on a predetermined operating condition is pneumatically activated. In order to realize the simplest possible structure, the pneumatic actuator 63 is uncontrolled and builds up (only) elastic restoring forces when the laying arm 27 is moved out of its neutral position in the laying direction V.

In order to keep the axial restoring force which presses the engagement wheel 43 against the free lateral side 18 of the last winding loop 17 substantially constant, the axial deflection between the carriage 53 and the rail 51 is kept substantially constant or at least in a boundary region. For this purpose, an unillustrated position sensor is used, which monitors a predefined minimum and maximum Sollauslenkamplitude by means of a control and / or regulating device (not shown in detail). If this is exceeded or fallen short of, the positioning robot 71 follows the rail 51 following the deflection movement of the laying arm 27, wherein the Nachrückschritt can correspond approximately to a thickness of the plastic pipe 3. In this way, it is ensured that the elastic restoring force is reduced by the trailing of the rail 51 by the periodic structure of the deflection. In order to realize the desired winding around the drum core 7 of the winding drum 5, the plastic tube 3 when winding around the drum core 7 as far as possible claimed in the longitudinal direction with a constant tensile prestressing force.

According to the invention, an electromagnetic brake, in particular an eddy current brake 67, is arranged on the carrier 23, in particular on the carriage 53, which can be moved from an active operating position, as can be seen in FIG. 10, into a passive operating position (see FIG. 9). The eddy current brake 67, which may optionally be provided and manipulated by an unspecified control and / or regulating device, serves to communicate the substantially uniform tensile prestressing force to the plastic pipe 3. As an example, the eddy current brake 67 may include two magnet rotors that rotate in an electromagnetically generated magnetic field, wherein the respective magnet rotor may be retracted and extended to adjust the electromagnetic braking force. To initiate sufficient friction deceleration forces in the plastic tube 3, a toothed belt 72 is provided, which is stretched around two pulleys of the eddy current brake 67. The timing belt 72 has transverse teeth to ensure a desired engagement with the plastic pipe 3 and the friction force transmission. In an alternative embodiment of the belt 72 may also be provided a longitudinally extending mountain-valley profile, which is shaped complementary to the plastic pipe 3.

The following describes how a new "winding" layer 15 "raised" in the radial direction of the winding drum 5 is initiated when approximately one winding layer has been completed on the drum core 7 or an already laid winding layer and a "new" layer is formed thereon. Reference is made in particular to FIGS. 2a to 4b.

FIGS. 2a and 2b show an operating state in which a first winding layer 15 is approximately finished on the drum core 7. The engagement wheel 43 runs on the cylindrical drum core 7, wherein the axial restoring force generated by the restoring device 61 presses the winding loop 17 just laid down axially against the adjacent winding loop. Before now the last winding loop 17 of the first winding layer 15 is completed, the contact wheel of the contactor 37 comes into rolling engagement with the inside 41 of the side flange I Ia. With continuation of the winding process, the contact wheel is deflected horizontally, whereby the control signal of the contactor 37 is sent to a control and / or regulating device, not shown. This causes after receiving the control signal vertical lifting of the laying arm 27 in that the positioning robot 71 lifts the carrier 23 and its rail 51 in lift direction A substantially no more than the thickness of the plastic tube 3, wherein the not shown vertical pivot stop the laying arm 27th in vertical lifting direction entrains to lift the winding drum side end 33 of the laying arm 27 by slightly more than the outer diameter of the plastic pipe 3 on the winding position just finished 15. In the axial end position of the winding drum-side end 33 of the laying arm 27 there is temporarily no contact between the engaging wheel 43 and the plastic pipe 3. By continuous winding is The plastic tube 3 is placed in the still remaining winding gap with the side flange 11a until the first winding loop of the "new" winding layer 15 forms.First, the freely accessible side region of the engagement wheel 43 comes in a lateral contact K with the lateral side 18 of the first winding loop 17 the newly laid winding position 15, wherein the rolling surface of the sprocket 43 is still briefly removed from the already completed winding position 15. Only after the first winding loop 17 entrains the sprocket 43 in laying direction V, the sprocket 43 lowers, s o that its rolling surface comes into rolling contact with the fully wound winding position 15. This operating state can be seen in Figures 4a and 4b, in which the sprocket 43 is on the one hand in rolling contact with the currently placed winding layer 15, on the other hand is biased with the uncovered side region in lateral contact K with the lateral side 18 of the first winding loop 17. In this operating state, the laying arm 27 is already crazy again in the axial direction relative to the carrier 23, as a result of which the rear part device 61 generates the ^' restoring force which presses the engagement wheel 43 against the winding loop 17 just laid. That the laying arm 27 is already deflected away from the axial end position is also apparent at the position of the contact wheel of the contactor 37, which is again in the passive operating state and no longer in rolling contact with the inside 41 of the side flange I Ia.

In Figure 6 it can be seen that the laying arm 27 is inclined in its axial end position shown in Figure 6 to the horizontal radial direction H _R at an angle α, according to which the laying arm 27, starting from the winding drum side end 33 of the right side flange I Ia away is inclined to the winding drum center. This ensures that the contact wheel of the contactor 37 has sufficient space for pivoting to the Control signal to generate and deliver without the end 33 of the laying arm 27 comes into contact conflict with the inside 41 of the side flange I Ia, I Ib.

In the course of the axial laying movement from the right side flange I Ia to the left side flange I Ib takes a (positive) angle α from, so that approximately in the axial center of the winding drum 5, the longitudinal extent of the laying arm 27 coincides with the horizontal radial direction H, while the laying arm 27 is inclined in the opposite axial end position in a (negative) angle of attack α, in particular of the same size, also towards the center of the winding drum 5. Also in this position, the contactor 37 can safely trigger by the contact wheel is swung laterally.

In both axial laying end positions of the laying arm 27, the radially extending side flange 11a, 11b does not interfere with the inclined laying arm 27.

The above-mentioned, not shown, in particular on the structure 30 can be accommodated control and / or regulating device can be used exclusively for the angular velocity of the winding drum 5 in dependence of the radial and / or axial position of the guide (the laying arm 27), in particular its wickelmommelseitigen end 33, adjust. It is clear that the control and / or regulating device can also take over the above-mentioned Steuemngsfunktionen. Preferably, the control and / or regulating device is firmly connected to the base plate 55. However, other mounting locations for the control and / or regulating device may also be considered.

When laying the plastic pipe 3 on the winding drum 5, the leading end of the plastic pipe is first threaded through an opening in the side flange 11 of the winding drum 5 and directly adjacent to the inside 41 of the side flange I Ia, I Ib manually by an operator for the first winding layer a low angular velocity (see Figure 11, START) wound, wherein the angular velocity U increases gradually.

Before the winding starts, the displacement detection of the laying arm 27 in the control and / or regulating device is initialized, namely set to "0". From this initialization of the laying process (at START according to Figure 11) begins a particular continuous Detecting the position of the laying arm 27. After first windings of the winding layer 15 (for example, see FIG. 1) rest on the drum core 7, the winding speed U is increased to a maximum winding speed U _max , so that starting at a variable or previously fixed setting position Xi for the first winding layer 15 the maximum winding speed Uma is reached. During the helical laying of the winding layer 15 in the so-called axial center region C of the winding drum 5 (see FIG. 6), which is between

and X ₂ , X ₅ and X ₆ , (FIG. 11) or between the axial setting positions P _a and P _b , (FIG. 6), the maximum winding speed U _{max should be} kept constant (see FIG. 11).

It is clear that the correct angular speed of the winding drum 5 is decisive for the winding success. Of course, the control process based on the peripheral speed at the respective winding position 15 can be adjusted. In the description of the figures, the winding speed is referred to as the control quantity for the sake of simplicity.

If the laying arm 27, coming from the adjusting means area C, reaches the predetermined axial setting position X ₂ or P _a or Pb, which can be determined, for example, by detecting the axial position of the laying arm 27 or by detecting the already wound winding material length, the control system triggers and / or regulating means a so-called Seitenflansch- or turning operation, in which first the angular velocity is gradually reduced gradually, namely to a minimum angular velocity U _m in, which is to be kept constant during the further delicate wall operation (X3-X4) (Fig. 1 1). If the wall operation is completed (at X ₄ ), in particular when reaching a parking position after the start of movement of the laying arm 27 to the opposite (relearning) side flange II a or I Ib the winding drum 5, the winding speed between X and X ₅ decreases according to the previous winding speed decrease between X ₂ and X ₃ continuously increases and reaches the maximum angular velocity Umax in the setting position X ₅ , which may be predetermined or calculated during the winding process.

It is clear that in Figure 1 1, not the direction of the axial movement of the laying arm 27 is shown, but only the winding speed U depending on an absolute, axial Stellwegbetrag IXI from the START. The axial direction of movement of the laying arm 27 changes at the respective setting positions X ', X ", at the end of which the minimum angular velocity U _m remains constant.

In general, the setting positions can either be predetermined by input to the control and / or regulating device, or calculated during the winding process and changed step by step depending on the winding progress.

FIG. 12 illustrates the turning operation on the basis of a path-time diagram in which the axial displacement X is shown in relation to the time t. At the moment when the turning position is reached by the guide, the laying arm 27, the time to is decisive. According to FIG. 12, before reaching the turning point t _0, a stepped graphene shape can be seen, in which the stepwise advancement of the laying arm 27 in the axial direction with respect to the leading winding layer during the normal winding operation should be clarified. It is clear that no step shape is necessary, but also other curved paths are possible. It should be noted that axial restoring forces which urge the laying arm 27 against the free lateral side 18 of the last winding loop are built up by advancing the laying arm 27 relative to the support 23 of the guide in the axial direction X by the progress of the winding; the coil winding, which builds up axially, presses the laying arm 27 against the elastic pretensioning device acting within the guide, as a result of which elastic restoring forces build up due to the relative movement.

Upon reaching the turning position X ₀ at the time t ₀ , the turning operation is triggered. If the turning position X _{0 is} reached, the control and / or regulating device causes a vertical free travel of the laying arm 27 away from the winding drum 5, whereby experience has shown that a radial clearance of 30 mm is sufficient to balance maximum radial balancing of the drum core 7 of the winding drum 5. Essential in the free movement of the laying arm 27 is to always make the drum-side end 33 contactless to the last laid winding layer 15. During the radial free travel time to to ti, are covered in accordance with about 0.8 revolutions of the winding drum 5, the laying arm 27 is not displaced in the axial direction and remains at the turning position X ₀ . Until the time ti, the axial distance (X) does not change. FIG. 11 and FIG. 12 are related insofar as the turning position X ₀ according to FIG. 12 essentially corresponds to the position X ₂ or X ₆ according to FIG. During the period t ₀ to, during which the laying arm 27 remains at the turning position X ₀ (X ₂ or X ₆ ), the angular velocity U remains unchanged.

From the end of the free travel ti the carrier 23 and thus the laying arm 27 (the end 33 no longer rests on the laid winding layer) further in axial lease towards the Seitenwandflansch I Ia, I Ib the winding drum 5 advanced to a complete concern of the winding drum side End 33 of the laying arm 27 on the Seitenwandflansch I Ia, 1 lb always during the entire cycle of the winding drum 5 to ensure. The axial advance path is illustrated in FIG. 12 by X ₀ to Xi. After completion of the advance at time t ₂ , the winding drum 5 can be further rotated by about 0.4 turns.

At the time (at the turning position X ₀ (X ₂ or X ₆ according to Figure 1 1), the speed for the further advancement of the guide is reduced.

From the end of the advancement (t ₂ , Xi), a position correction of the laying arm 27 and the carrier 23 can be performed, for example, to adjust the restoring forces in the rail carriage storage or to change the position of the laying arm 27 relative to the winding drum 5. The correction phase may take about 0.6 revolutions of the winding drum 5.

At the end of the correction t ₃ , the guide, namely the carrier 23 together with the laying arm 27, is set in an opposite direction to the laying direction to move the laying arm 27 in contactless relation to the side wall flange 11a, 11b of the winding drum 5. In this case, the return return path is approximately equal to the advancement path, but can also be realized larger or smaller, so that it is ensured that the winding drum end 33 of the laying arm 27 no longer reaches the contact area of the side wall flange 11a, 11b of the winding drum 5. The return can take about 0.2 revolutions of the winding drum 5. At the end of the return t _{4 of} the laying arm 27 is lowered back to the already laid winding layer 15 and thus comes into rolling contact. During the lowering of the laying arm 27 until the time t ₅ , the carrier 23 of the laying arm 27 remains in the axial position, which in particular corresponds to a neutral position in which no restoring forces act. At time t ₅ reaches the newly laid winding loop in the lateral abutting contact with the engagement wheel 43 and takes the laying arm 27 in Her-laying direction with what should be represented by the downward sloping graphene shape. In order not to let the restoring forces become too large, as described above, the carrier 23 is tracked relative to the adjacent laying arm 27 by the positioning robot 71. At the earliest at time t ₅ should be started with the change of the angular velocity to U _max in order to achieve the fastest possible winding along the drum core 7.

In general, the axial displacement X refers to the actuating movement of the carrier 23, wherein the displacement of the carrier 23 by the positioning robot 71 and the flexible adjustment of the laying arm 27 due to the sliding bearing on the carrier 23 and the winding progress in the case is about the same, when the laying arm 27 is not supported on the side wall flange 1 la, l lb of the winding drum 5 or the lateral side of the last winding loop.

Details of a preferred embodiment of the laying arm 27 according to the invention are shown in FIGS. 13 to 18, wherein the same reference numbers are used for similar or identical components of the laying arm 27 previously described with reference to the previous figures in order to facilitate the readability of the figure description.

The laying arm 27 comprises three main components, namely the arm base 28, at which the winding material is introduced, the winding drum end 33, on which the winding material is discharged, and an intermediate elongate support structure 30, which forms the majority of the laying arm 27. The winding drum-side end 33 is releasably and interchangeably connected via interfaces 110, 111 with the support structure 30. In this way, it is sufficient, when changing the dimension of the winding material, only to exchange the winding drum-side end 33 for a dimension-adapted, while all other components (28, 30) of the laying arm 27 can be maintained. These other components are independent of the dimension of the winding material. Only the winding drum-side end 33 is winding material specific due to the contactor 37, which will be explained below as an alternative embodiment, and the winding material delivery 34 executed.

As can be seen from Figures 13 to 18, the contactor 37 is formed in an alternative embodiment without contact wheel, but realized with on the side flange wall I Ia, I Ib schleifend running actuator projections 101 a, 101 b. The actuating projections 101a, 101b are part of a closed bow or ring structure of the contactor 37, which in plan view has a triangular shape with two equal length long legs, which lie at an angle of about 15 ° to the longitudinal direction of the laying arm 27. The long legs extend to a connecting front short leg, which forms the free end of the contactor 37 and the winding drum end 33. Corners of the triangular ring structure are rounded.

The actuation projections 101a, 101b, together with the ring structure, are pivotably mounted about a pivot axis 100 extending in the vertical direction, so that the respective actuation protrusions 101a, 101b can be retracted so as to pivot with the respective sidewall flange 11a, 11b such that their corner area is level with the outer surface the abutment portion 38a, 38b and no distance projects laterally beyond the outer surface. In this release position of the respective actuating projection, the abutment region 38 of the winding drum-side end 33 of the laying arm 27 touches the inside of the respective side flange wall 11a, 11b. If the laying arm 27 is moved away from the respective side flange wall 11a, 11b and the contact area 38 is released, then the ring structure of the contactor 37 automatically moves into its middle, unactuated position (see FIGS. 13-18) by means of a force means (not shown) , such as a spring, preferably a torsion spring. The spring preload can directly engage the ring structure or on a gear part, such as the pivot axis 100, etc.

The contactor 37 is provided with an angle gear 103 for transmitting the pivotal movement of the vertical pivot axis 100, which is rigidly coupled to the ring structure, into pivotal movement about a transmission shaft 105 extending in the longitudinal direction of the laying arm 27. The translation of the angular gear 103 for transmitting the pivoting movement is preferably 1: 1.

A signal generator (not shown), which is arranged on the supporting structure 30 and which outputs an electrical control signal after the start of movement or after exceeding a predetermined swiveling amplitude of the ring structure, is communicated to the transmission shaft 105 in order to inform the control and / or regulating device that the turning operation is to be initiated. The control signal can be triggered immediately at the start of the swing or only delayed after reaching a predetermined swing amplitude. The transmission shaft 105 is divided into two, with the path sensor-side shaft portion 107 coupled to the support (30) side shaft portion 109 by means of a releasable dog clutch 110 that allows disassembly of the front and rear shaft portions 107, 109 from each other. At the shaft portion 109 of the signal generator connects. In addition to the dog clutch 110, the guide and holding plates 31b and 31a form a separable interface 111 for separating a housing plate portion facing the winding drum 5 from a base-side housing plate portion.

The mounting interfaces (110, 111) allow the winding drum end 33 together with its functional elements, such as the Wickelgutabgabe 34, Abgaberäder 35, Kontaktgeberteile and decouple the mechanical communication of the contactor 37 toward the signal generator to the device of the invention and in particular the majority of Verlegearms invention 27 to adapt depending on the application for a certain sized winding material. It has been found that those components in the transport space 32 on this side of the mounting interfaces (110, 111) can be interpreted for a large number of different sized winding goods, but the winding drum-side end 33 is to be adapted to the winding material specific to the dimensioning. In particular, the winding material delivery 34 and the actuation projections 101a, 101b projecting from the abutment region 38 can be adapted to the winding material thickness.

Particularly advantageously, the purely mechanical realization of the contactor 37 up to the signal generator on the basis of releasable couplings, such as the dog clutch 110, so that no electronic signal transmission between the winding drum end 33 and the carrier side arranged control and / or regulating device is necessary. In this way, an exchange of the winding drum end 33 can be done purely mechanically, whereby even inexperienced operators can perform a change of the winding drum side end 33 for adjusting the laying arm 27 to be wound winding.

The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments. LIST OF REFERENCE NUMBERS
