Abstract

The invention relates to a method for winding a strip (17) consisting of a plurality of parallel threads (18) onto a rotating warping drum (2), wherein the winding position of each individual thread is determined with the aid of a thread guide (21) which is associated with a thread selection device (8) and which is allocated to said thread. The thread guides (21) are displaced in the direction of the axis of rotation (6) of the warping drum (2) from a rest position into a working position and the individual threads (18) are seized successively by an internal thread carrier (30) associated with the warping drum (2).

Description

Method and device for winding a band consisting of a plurality of parallel threads onto a drum rotating about a rotary axis

The invention relates to a method and an apparatus for winding a strip consisting of a plurality of parallel threads onto a winding body rotating about an axis of rotation. Such methods and devices are used, for example, in textile technology in weaving preparation for warping the warp. But winding processes are also in other areas such. required in the wire industry. The present invention is not limited to textile applications and the term "threads" covers any elongated, windable element, irrespective of the cross-sectional shape or the material.

A requirement of modern warping methods is, for example, that work has to be carried out at high speeds, whereby a change in the composition of each wound strip should be ensured. This requirement arises in particular in so-called pattern chains or short chains. However, any change in the band composition, be it in the type or sequence of the threads or in the wound bandwidth, requires a machine standstill, which considerably delays the working process.

It is therefore an object of the invention to provide a method and an apparatus of the type mentioned above, with which rapid tape changes or different tape compositions are possible at a high production speed. This object is achieved in procedural terms by a method having the features according to claim 1 and in device-related terms by a device having the features in claim 15. In conventional warping machines, the threads are already brought to the warp blade on the correct thread density and bandwidth. This arrangement visibly complicates any modification of the tape. These disadvantages can be eliminated if the winding position of each individual thread on the winding body is determined with a thread guide associated with this thread. The thread guides thus replace the sharpening blade, but in contrast to this they can approach arbitrary positions. The yarn guides are therefore preferably adjustable in the direction of the axis of rotation from a rest position to a working position. Da¬ with the yarn guide can be used alternately and so change the composition of the tape to be wound arbitrarily.

Particularly advantageously, a set of threads consisting of a plurality of threads, preferably of a different type, is introduced to a thread selection device arranged in the winding area of the winding body, whereby individual threads are pulled off as work threads over the thread guides and form the strip, while the remaining threads are arranged as stock threads at the Fa¬ denwähleinrichtung by means of a respective clamping point are held clamped. This procedure makes it possible to change the strip while the winding body is rotating continuously, which, as can be seen, considerably speeds up the work process.

In this case, it is advantageous if, after at least one first winding sequence, the working threads of the wound strip are held and clamped on the thread selection device and if in at least one second winding sequence the working threads of the strip have a different composition than during the first winding sequence. The composition of the band can also be the same at several adjacent coils. Finally, it would also be conceivable that the threads of a ribbon would not the winding sequence are separated, but that the tape is guided at the end of a roll directly to the beginning of an adjacent roll.

A taking place at full bobbin rotation yarn transfer can be achieved particularly advantageous if the selected work threads are first stretched by the thread guide in a driving position on the winding body in which they are stretched between the yarn guides and one nip approximately parallel to the axis of rotation and that in During a winding body rotation, all working threads in the entrainment position are detected successively by an inner thread taker associated with the winding body and then separated from the clamping point. After disconnecting from the clamping points, the thread guides can be driven with their work threads in the tape winding position on bandwidth. This on-the-fly transfer of the clamped supply threads as working threads onto the winding body can take place at high speeds and within a single turn of the winding body.

After the construction of a tape reel, in turn, all working threads can be sequentially grasped by an outer thread follower synchronously rotating with the winding body and then clamped again by the clamping point and at the same time separated from the thread guide. This practically results in a flying return of the working threads to the waiting position at the clamping points.

On a cone warping machine, it is obviously necessary for the thread selection device for the conical winding of the strip to be displaced on a shear table in the direction of the axis of rotation or at right angles thereto. The Schärtrom¬ mel forms the bobbin. Evidently, it is necessary in the context of a warping process for the correct presentation of the warp on the weaving tree to introduce Teil¬ elements in the thread assembly. The insertion of Teil¬ elements requires in conventional methods usually always a machine downtime. This disadvantage can be avoided in the inventive method in that at the beginning of a tape roll with at least a portion of the threads at least one point on the winding body with rotating Wikelkel a compartment is formed and that introduced into the open compartment a sub-element becomes. Alternatively, the compartment can also be formed with shedding combs which are based on oi nerα 5vnc υvn; nit: u ^; ! eke l kc ^' rpor are arranged in tdroheruien and thick αriootαuicn Imino- rino. Such a thread pitch can preferably serve to form a crosshair. Such a thread cross later facilitates further processing, for example in weaving. Similar to the flying transfer of the working threads to the winding body, the shedding, in particular the formation of the crosshairs, and the introduction of the partial element at full operating speed thus also take place. In certain cases, it would also be conceivable to use this type of shedding in conventional methods in which not every individual case is deposited via an individual thread guide.

A particularly advantageous shed formation results if, for hitting the crosshairs, at least two shed combs arranged successively on the winding body relative to the circumferential direction are moved from a position approximately tangential to the outer circumference into a shedding position, in which the combs project radially from the outer circumference and that during a winding body rotation, the threads are preferably deposited alternately on the comb ends and between the combs. The shedding combs can be relatively easy with a Partial rotation are moved to their working position. However, this process can of course also be used for the finishing treatment. This is not about a cross formation, but about a separation of the threads. For the size division, a plurality of shed combs arranged one behind the other are designed such that a shed is formed in each case only for individual threads. If, in addition, a size distribution is provided, it is preferably carried out before the matrix cross formation.

Evidently, the shedding and the introduction of the sub-element before starting the tape winding position, the thread guides are first moved to a read-in position for depositing the threads on the shedding combs. In this Einlese¬ position, the threads are less close together than at the later tape winding position.

Preferably, a partial rod is first inserted into an open compartment, after which the compartmentalized compartment forming the compartment in question is moved back into the rest position and lastly the threads divided by the partial staff are directed onto a partial element, preferably a partial cord or a partial cord Sub-band stripped wer¬ the. The partial cord or the partial band is thus not actually drawn into the compartment, but the threads are transferred to the partial cord or the partial band.

Likewise, at the end of a band winding with at least one part of the threads, at least one point on a synchronously rotating with the winding body and surrounding outer ring a Fa¬ are crossed to Fachbildung, wherein in the geöff¬ designated tray a sub-element is introduced and wherein the Fach¬ education preferably with analog means, ie with Fachbilde¬ combs takes place, as at the beginning of the tape roll. In this way, can be wound on the winding body, a plurality of tape roll with the same or with different thread repeat to each other or side by side, the Wikelkelkörper continuously rotates.

In terms of the device, it is expedient if one thread guide and one clamping point are assigned to a thread guide module which has a gear for adjusting the thread guide and a movable clamping cutting unit with a clamping point for clamping the thread and a cutting device for tearing off the thread guide Thread has. The cutting and clamping of the threads er¬ follows in this way virtually the same location, making the flying thread change is possible with rotating bobbin.

The gear of the yarn guide module is preferably a Zugmit¬ telgetriebe with a traction means, in particular with a Zahnrie¬ men, on which the yarn guide is arranged such that it is movable on a yarn guide path approximately parallel to the axis of rotation of the Wickel¬ body. The traction mechanism can be moved very quickly and precisely, for example with a stepper motor. Conceivable, however, would also be other types of transmission, for example a connecting rod, at the end of which the yarn guide is arranged.

The clamping-cutting unit can be movably mounted approximately at right angles to the thread guide path so that the clamping point is displaceable relative to the winding body circumference between a radially outer rest position and a radially inner thread transfer position. This lifting movement can be made for example via a pneumatic pressure cylinder.

As can be seen from FIGS. 1 and 2, a warping machine designated as a whole by 1 consists essentially of one Warping drum 2 as a winding body with a cylindrical Ab¬ section 3 and a conical section 4. The warping drum is mounted about a winding body or drum axis 6 rotatably in a frame 5. A shear table 7 rests on a Schärtisch¬ guide 11 and is displaceable on this parallel to the axis of rotation 6 in Pfeil¬ direction c. Arranged on the tendering table 7 is a thread selection device 8, which is also displaceable in the direction of arrow d relative to the warping drum and at right angles to its axis of rotation.

The yarn selection device curves over a segment of, for example, 90 ° about the surface of the warping drum 2. In the circumferential direction, a plurality of yarn guide modules 20, which are shown only schematically here, are arranged on the yarn selection device. From a creel, not shown here, or from another thread dispenser device, a group of threads 9 is withdrawn, with each individual thread being guided to one of the thread guide modules 20. Suitable devices, such as Yarn brakes ensure that the threads always remain tensioned.

For the shed formation for the preparation of crosshairs or for the sizing division at the beginning of a coil, an inner ring 12 is arranged on the zy¬-cylindrical section 3 of the warping drum 2, which carries the means for crosshairs or Schlich¬ teteilung and which together with the Drum turns. The inner ring 12 is guided in drum longitudinal grooves 13 and can thus be displaced in the direction of the arrow c, like the shear table 7.

For shedding, in particular for crosshair formation at the end of a winding, an outer ring 14 is provided, which concentrically surrounds the drum sheath and which is synchronous with the drum is drivable. The outer ring is mounted in an outer ring bearing 15, which in turn supports abge¬ on an outer ring slide 16 and is linearly displaceable in this direction in the arrow direction c. The outer ring 14 also carries the means necessary for crosshairs.

In a control cabinet 10, the components are housed to control the warping machine.

FIG. 3 schematically shows the entirety of the mechanical functional groups on the warping machine with the associated drive motors, namely essentially the warping drum 2, the frame 5, the shear table 7 and the thread selection device 8. In addition, the inner ring 12 and the outer ring 14 are provided with the respective actuating means. It can be seen that here both the inner ring 12 and the outer ring 14 are elements which are detached from the warping drum 2 and which are drivable synchronously with the warping drum 2.

Figure 4a shows a partial perspective view of a Fadenwähl¬ device with yarn guide modules of a warping machine. The Fa¬ denwähleinrichtung 8 has a plurality of yarn guide modules, wherein the modules 20 ', 20'',20''' and 2O ' ^{V are} successively arranged in the circumferential direction. In Figure 3, a ei¬ nem inner ring associated shedding comb 40 is further recognizable, the configuration and operation will be described later in detail. A yarn guide 21 can be moved or positioned along the drum axis in the direction of the arrow e. The movement of the thread guide 21 can take place with a traction mechanism 33. Of course, other means for moving the yarn guide 21 are conceivable, such as pneumatic or hydraulic systems. Hereinafter, a single yarn guide module 20 will be described in more detail with reference to FIGS 4 to 6. The module has a holding plate 32, to which a gear unit 33 and a clamping cutting unit 22 are attached. The gear unit ver¬ adds a traction mechanism with a toothed belt 29. The toothed belt is driven by a thread guide drive 34, which is preferably a stepper motor. On one of the two parallel Zahnriementrums a yarn guide 21 is fastened be¬, which can zurück¬ in the direction of arrow e a yarn guide stretch FS zu¬. In the rest position RS, the thread guide 21 is set back behind the clamping-cutting unit. The clamping-cutting unit 22 is on a lifting carriage 26 angeord¬ net, which is slidably mounted in a guide 35. The driving means used here is a pneumatic pressure medium cylinder 28.

The clamping-cutting unit has a Doppelhebearm 25 which is articulated on the lifting carriage 26 and the upper lever arm via a pneumatic pressure medium cylinder 27 can be activated. The actual cutting device 24 is formed on the lower lever arm by a cutting edge. Immediately behind the cutting plane is a nip 23, which is also activated via the Doppelhebearm 25.

The supplied working thread or supply thread 18/19 is introduced via a thread guide tube 36 which opens on the side of the Dop¬ pelhebelarms so above the nip 23 that the Fa¬ the lies on the thread guide section of the thread guide 21. The thread guide has a notch or groove which prevents the thread from sliding away.

For a better understanding of the following functional description of the yarn guide module 20 is also the trom- mel assigned inner Fadenmitnehmer 30 shown. This is not shown here by means means able to detect a clamped in the correct position clamping thread and entrain.

As long as a thread in the starting position shown in FIG. 5 is clamped on a thread guide module, it serves as a supply thread 19, which can be included at any time as a working thread in the warping process for forming a strip. For this purpose, according to FIGS. 7a and 7b, the yarn guide 21 is activated, so that it covers part of the yarn guide section FS and first assumes a thread take-up position FM. The lifting carriage 26 is already located in the lowered position shown in FIG. The thread supply required for achieving the thread take-off position FM is withdrawn via the thread guide tube 36. The rotational movement of the drum is tuned to the movement of the yarn guide 21 that immedi bar after reaching the thread take-up position FM, the lower Fa¬ denmitnehmer 33 entrains this and any other working thread of the present winder.

Immediately after the secure grasping of the thread, the nip 23 is released, so that the working thread is pulled off at the circumferential speed of the inner thread driver 30. This situation is shown in FIGS. 8a and 8b. Until then, all active thread guide modules on the thread selection device are working simultaneously.

Following this, according to FIGS. 9a and 9b, the thread guide 21 is moved a little further along the thread guide section FS in order to be read into a shed 40 for beating a crosshair. This shedding process will be described in more detail below. The Fachbildekamm for a Crosshairs have U-shaped forked combing ends 42, in each of which a single working thread can be deposited. Filaments can also be deposited between the individual combing ends 42. As is shown symbolically in FIG. 9a, each yarn guide 21a, 21b, 21c, etc. is then moved in sequence by thread guide modules following in the circumferential direction to such an extent that a work thread is alternately placed on a comb end and between a comb end. After hitting the crosshair and after introducing a Teilele¬ ment in the manner described below, all active thread guides 21, 21a, 21b, 21c, etc. drive their respective work threads on the actual winding position of the belt 17, the width of which, apparently, much smaller The thread guides 21 maintain their relative position to one another until the end of the reel is reached, the entire thread selector being moved on the sharpening carriage.

Once the end of a tape roll is reached and as soon as there are formed with similar agents crosshairs, in turn, all active thread guide 21 move to an outer Fadenmit¬ receiving position FM, in which all working threads 18 are passed to an outer Fadenmitnehmer 31 or entrained by this. This outer thread driver is associated with an outer, the drum concentric surrounding and co-rotating with the drum outer ring 14, which is shown only symbolically in Figure 10a / 10b. This "gathering" of the threads is done in preparation for the cutting operation shown in Figures 11a / 11b.

The lifting carriage 26 is driven at each yarn guide module 20 in the upper end position, so that the nip 23 can detect the abge¬ extended thread. Practically at the same time is the Cutting device 24 is activated, on the one hand freed the just worked working thread 18 from the thread guide 21 and at the same time held back as a supply thread 19 at the nip in the ready position.

As can be seen from FIG. 12, the means for striking a crosshair at the beginning of a coil are arranged on the inner ring 12. The situation illustrated in FIG. 12 corresponds approximately to that in accordance with FIG. 9, with adjoining yarns being alternately read in successively arranged shedding combs 40a, 40b. With 30 again symbolically the inner Fadenmitnehmer is indicated. By alternately overcoming the shedding combs, it is evident that a frame cross 50 forms with an opened compartment 51 into which a partial element can be inserted. The sizing division can also take place in approximately the same way. In contrast to the formation of the crosshairs, a multiplicity of successively arranged shed combs must be provided for sizing. In addition, the shedding combs for the sizing division are designed differently (see figures 28a and 28b).

Further details of a shedding means are shown in FIGS. 13 and 14. The curved shedding comb 40, for example made of plastic material, is fastened to a rotatable comb shank 41. A partial bar 43 is arranged displaceably parallel to the comb shaft. At the end of the extended comb shaft 41, a pincer-like sleeve holder 45 is provided, which clampingly grasps a partial sleeve 44. The approximately cylindrical partial sleeve has a partial cord spindle 46 which is screwed zent¬ risch in the Teilschnurhülse, so that an open annular gap 55 remains. A suitable partial cord 49, which can be pulled off via the annular gap 55, is wound on the partial cord spindle 46. The Teilschnurhülse 44 has on the the end face of the partial rod 43 side facing via a An¬ circuit element 47, to which the partial rod 43 and the Teil¬ cord sleeve 44 can be coupled.

The extended partial rod 43 thus captures the partial cord sleeve 44 fixed in the sleeve holder 45, which otherwise has approximately the same outer diameter as the partial rod. Subsequently, the sleeve holder 45 is opened, so that the entire peripheral region of the partial cord sleeve 44 is exposed. This makes it possible to strip the split thread assembly from the partial rod 43 to the withdrawn partial cord 49.

For this purpose, a thread scraper 48, which is shown in Figure 15a and which is ver¬ pushed in the direction against the Teilschnurhülse 44 out. FIGS. 15a / 15b show a shedding comb 40 in the standby position, that is to say with comb ends 42 protruding radially outwards. The shifter rod 43 is still pulled back, so that according to FIG. 16 the shedding comb can be wound over. In each case, the upper threads 53 are in the U-shaped comb ends 42 and the lower threads 52 are between the Kammen¬ directly on the comb shaft 41. The distance between the lower and the upper threads forms the open compartment 51. Depending on the bandwidth of the Later Schärbandes the entire Fach¬ bildekamm or only a portion thereof is wrapped.

As soon as all active working threads have been read into the shedding comb, the partial rod 43 according to FIG. 17 is extended, and thereafter the shedding comb 40 is turned back into its radially inner armature.

This situation is shown in FIG. 18b. The upper threads 53 now rest directly on the partial rod 43 and the lower threads 52 still rest on the comb shaft 41. The partial rod 43 has detected the partial cord sleeve 44 end and the latter is freed from the sleeve holder 45. Now, according to FIG. 19, the thread scraper 48 can be advanced, which strips the lower and upper threads 52/53 beyond the sub-line sleeve 44 onto the sub-line 49. Subsequently, the thread scraper 48 moves back and the shedding comb 40 remains in this waiting position according to FIG. 20 until it is turned out to form a new shed.

The shed formation at the end of a roll takes place with similar means as at the beginning of the roll, i. also with shedding combs. As already mentioned in the introduction, these shedding combs are assigned to the outer ring 14 whose diameter is dimensioned so that it is larger than the largest possible winding diameter. Unlike the beginning of the winding, however, it is not a partial cord but a flexible partial ligament that is introduced into the open thread compartment as a partial element, the design of the compartmentalised part and the method steps not being the same as on the inside. According to FIG. 21 a / 21 b, a curved shedding comb 40 with comb ends 42 is likewise arranged on a comb shank 41. The flexible sub-band 54 with its angled end is arranged below the comb shaft 41 and can be advanced from the inside of the drum. An upper partial rod 56 can also be extended parallel to the comb shaft 41. In addition, a stripper sleeve 57 is provided which surrounds the entire rod 56. In the illustrated starting position, in turn, lower threads 52 and upper threads 53 are read into the shedding comb 40, i. the thread guides 21 (FIG. 9a) assigned to each thread ensure that the threads assume the correct position of overwinding.

According to FIG. 22, the reading-in process is completed and the partial rod 56 is moved into the open compartment 51. Anschlies- send is turned off according to FIG. 23 of the comb shaft 41 so that the upper threads 53 lie on the partial rod 56 and the lower threads 52 on the comb shaft 41.

In a next step according to FIG. 24, the stripping sleeve 57 is extended, with the lower threads 52 falling onto the sub-band 54. On the other hand, the upper threads 53 initially lie on the end of the partial rod 56. The end of the partial rod is aligned with the angled end of the partial band 54.

As soon as the stripper sleeve 57 travels the last distance, the upper threads 53 fall onto the finished lap, but outside the subband 54 (FIG. 25). Thus, the Teil¬ element is introduced and can be advanced to form a pitch on the next following winding by a winding width. The shedding comb 40 is in turn rotated into the active position for the shedding and the partial rod 56 or the shrouding sleeve 57 are retracted into the starting position (FIG. 26). Of course, the method described with reference to FIGS. 21a / 21b to 26a / 26b can also be applied to the winding start or to the inner ring.

A complete winding process is described below with reference to the sche¬ matic representation according to FIG 27. The diagram shows from bottom to top ascending the individual winding sequences, namely with a viewing direction at right angles to the drum. In the upper third of the image, the viewing direction extends tangentially to the warping drum 2 with the cylindrical section 3 and the conical section 4, as well as with an already finished roll 37. The lower two thirds of the illustration show practically a development of the drum shell in the ver¬ different operating sequences, with the right angle position of the drum is specified. A winding process begins with the presentation phase 60, in which the yarn selection device 8, as described above, transfers the work threads 18 to the drum with the aid of the active yarn guides 21A and brings them into the correct relative position. The diagram shows a total of 6 active yarn guides 21A. In the case of two passive thread guides 21P, the corresponding thread guide modules remain in their neutral ready position, in which the stock threads 19 rest.

In the lower overwinding phase 61, the working threads 18 are scanned into the lower shed 40 using the active thread guides 21A. As described above, the divided yarns are pushed onto the part string and subsequently the active yarn guides 21A move the yarns together on the one hand to the band width B of the warp band 17 and on the other hand simultaneously to the left to the bottom point 38 of the conical portion 4. At the end of this process the drum has traveled a revolution of 360 °.

Now follows the actual winding phase 62 to build the Wiε- ckels 37, wherein depending on the thread quality as many drum revolutions Nx360 ° are required until the desired winding height H er¬ is sufficient.

After the winding 37 has been completed, the upper winding phase 63 follows for the threading of the threads into the upper compartmentalizing combs 40 on the outer ring 14. For this purpose, the active thread guides 21A travel further to the left and at the same time again apart to the insertion width. For the shedding and for advancing the sub-band in the open compartments, the drum again requires a full revolution of 360 °. Subsequently, the yarn guides 21A move along a row in order to transfer the working threads 18 together to the outer Fadenmitn¬ mer 31, wherein the yarn guide modules cut the Arbeitsfä¬ the and in turn clamped detect. This action is shown as upper presentation phase 64.

Without stopping the drum can now be wound in the same manner, the next winding, possibly at the Fadenwähleinrichtung 8 other threads are retrieved. As can be seen, the inner ring 12, the outer ring 14 and also the thread selection device 8 move to the right by a bandwidth B.

Shown in FIGS. 28a and 28b are shedding combs for the shallow division. With the aid of a first shedding comb 40 '(FIG. 28a), a first thread is deposited in each case into a comb end 42' arranged at the beginning of the comb. Further comb ends are arranged at predetermined, periodic distances from each other, whereby each individual threads form a compartment. Through this subject, a sub-element, such as a partial rod is feasible. A second shed comb 40 "following the first shedding comb (FIG. 28b) has comb ends 42" for a second thread or second threads, the comb ends of the first shedding comb being opposite the first shedding comb around a thread are offset. Similarly, the next shedding combs are formed, i. In the case of the third shedding comb, the respective comb ends would have been offset by a further point, etc. In the example according to FIGS. 28a / 28b, seven shedding combs would therefore be necessary for the shimming division.
