Description

The invention relates to a method for the disposal of flexible Material that is in the form of at least one moving material web is present, which is in a feed direction at a feed path speed supplied to a disposal facility is used, especially for the disposal of used embossing foil web during the operation of a hot stamping device.

During hot stamping, one becomes in a hot stamping device impressive material layer at constant speed guided an embossing gap between an embossing tool embossing cylinder and a counter pressure element, in particular an impression cylinder is formed. Above the A sheet of embossing foil is moved with the material layer so that it during an embossing interval at the same speed how the material layer moves. During the minting interval is to be embossed on the embossing foil web, for example discrete embossing units one behind the other like pictures or texts, or a part of one to be stamped Color layer, under the influence of pressure and temperature on the Transfer material layer. The embossing foil web is replaced by a suitably designed transport device of a preferably withdrawn roll-shaped foil stock and through the embossing gap moved, and the used stamping foil is removed and must to be disposed of.

In known hot stamping devices of this type, the Dispose of the used embossing foil on a Winding storage roll is wound up. If the role on the Waste side is full, the embossing process or the supply to the waste roll is interrupted. This is causing usually reducing the overall milling performance Machine downtime. It can also stop the system or when restarting to malfunctions and / or Production of scrap come with the embossed material. to Avoiding such problems will be continuous disposal used railway material.

One from GB 2 254 586 (State of the art according to the preamble of claims 1, 8 and 14) known embossing device has on the waste side in the manner of a Shredders or document shredders working Disposal facility that uses the used web material upstream conveyor station is supplied. This has two counter-rotating transport rollers, between which the Web material is clamped and conveyed through. The discharge side free end of the web material emerging from the conveyor enters the shredder 's entry slot, which holds the web material in tears small pieces of web material and conveys them to a collection container, which is emptied from time to time. Especially with relatively thin, little inherently rigid web material can be found in the cutting unit of Shredding to malfunction, for example incomplete tearing of the material or by clogging the Cutting unit, come.

The German patent DE 648 075 shows a cross cutter for Paper webs with two revolving drums, one from the Web material is partially wrapped and a recess which is spanned by the web material while the other has a rotating knife synchronized with this drum, which cuts through the sheet material spanning the recess. A similar sheeter used to cut cigarette paper is provided is known from DE 37 30 810.

The invention has for its object the disadvantages of the prior art to avoid technology. In particular, a method and a Device are specified with which a trouble-free continuous disposal especially of very thin Web material, such as used embossing foil web, is possible.

To achieve this object, the invention proposes a method with the Features of claim 1 and a disposal device with the Features of claim 8.

The invention provides that in a generic disposal method a first web section of the material web and a preferably at a lateral distance from the first Web section arranged second web section of the material web are recorded and that the material web in a between first and the second web section intermediate section to Generation of pieces of web material is severed. The Pieces of web material can then be collected and possibly further Processing steps are subjected. By that preferably Flat holding of the web material on both sides of the separation area can be achieved that the web material during the separation process is not drawn into the area of separation, so not yields to a preferably mechanically acting separating member, but this one resistance that makes separation easier opposes. This is particularly advantageous for very thin ones low inherent stiffness sheet material, such as Stamping foil webs, their typical thicknesses in the range between 10 and Can be 20 µm. Such usually with a carrier film made of tough plastic Embossed foil webs tend to tilt in cutting units conventional shredder, the cutting units in cutting engagement have cutting rollers standing together because of lack of film tension, not or only incompletely to be cut and / or clog the cutting units. By holding the web material according to the invention on both sides of the separating section or intermediate section the web material is kept under tension in the separating section, which favors an easy, reliable and complete separation.

A further development provides that the web material in one floating freely between the held track sections and / or the intermediate section or the separating section held taut is severed. This can be a complete Dissection are encouraged because a used for separation Separator the area defined by the web material can penetrate completely. To achieve reliable Separation, it is advantageous to determine the length of the free-floating, not in contact with a surface to keep the intermediate section as short as possible in order to a due to the elasticity of the web material to be cut favored evasion of the web material at Minimize severing. The length of the free intermediate section can accordingly be less than 1 cm, in particular between approx. 1 mm and approx. 5 mm.

A preferred development provides that the first path section in the feed direction at the front and the second path section in the feed direction is behind and that the severing transversely, in particular essentially perpendicular to the feed direction he follows. With this usually over the whole The width of the material web guided cross separation can do this Front track section separated and easily disposed of while the ones behind are still being held can and serve as the front piece of the subsequent separation can. By holding on to the rear section of the track it is also ensured that the material web fed cannot slip out of the disposal facility, but is always kept safe.

Alternatively or additionally, it is also possible for the first Track section viewed in the feed direction at least in sections is next to the second railway section and that the separation at an acute angle or essentially parallel to the feed direction. Through a longitudinal cut or several, preferably parallel to one another, in particular longitudinal cuts made at the same time may be narrow Strips of web material are generated, which may still be due suitable cross sections or cross cracks can be shortened. Streaks that arise can be advantageous after separation still in full contact with a conveyor device carrying it remain and thus in an orderly arrangement Disposal steps are fed.

Different, preferably the separation or cutting behavior of the web material adapted procedures are used. Particularly preferred is a process in which the web material is used for severing is cut with a free edge, i.e. with a mechanical separating element that creates the separating effect no counter element, such as a counter knife or the like, is required. Corresponding separation devices are particularly durable and low wear, especially in the separation area free-floating web material a cutting edge only with the (softer) Web material comes into contact. It is also possible, that the web material for severing in the intermediate area is melted, especially along an essentially straight melting line. This, for example, using a hot air blower or heated or glowing wire or the like feasible variant is particularly for web material suitable with thermoplastic. An advantageous one Variant is characterized in that the web material for cutting in the intermediate area on many, preferably line-like locations, preferably at the same time, is perforated and then the perforations be enlarged until they grow together. This for example can be carried out by means of a pressed-on sawtooth knife The method is particularly suitable for severing Plastic films, required because of the initially punctiform Action of a separating element on the film web for production sufficient separation pressures only low forces and can used particularly advantageously for tensioned web material in which the enlargement of the perforations is partly due to independently progressive cracks in the tensioned material can be supported.

A further development provides that a track section for holding on a pressure surface moved in the feed direction Structure of static friction or sliding friction pressed on becomes. Compared to an also possible, essentially This means that point or line-shaped retention is required possible large-scale holding on a pressure surface of for example one or more square centimeters for a secure hold with little strength. Furthermore, the flat attack of the holding force a material damage of the web material that lead to an unintentional crack could, reliably avoided. Is very particularly preferred it when to hold a track section between this and a negative pressure is generated on the pressure surface. A section of track is held from below, so to speak, while that of The side facing away from the pressure surface remains free of holding means, which in particular has enough space to attach a suitable separation device can be created. A pressure surface can in particular by an outer surface of a revolving conveyor element of a suction conveyor is formed be, for example a suction belt, especially one Suction roll.

Disposal can be performed after the severing Include the step of collecting separated pieces of material. A method is preferred in which after the severing the pieces of web material from a one carrying and / or holding them, moving contact surface can be detached. This can for example with a spatula or squeegee or the like, but is preferably non-contact carried out by means of at least one air flow which the pieces of web material lifts off the pressure surface, in particular sucks. Blow off and suction can also be combined be used for detachment.

Due to the continuous dismemberment of the web material into small pieces of web material becomes space-saving packaging of the used material favors, since small pieces of material can be stowed with higher packing densities. The Packing density can preferably be increased by that the collected pieces of web material, preferably in batches, be compressed, for example to less than that Half, a quarter or an eighth of the packing volume in loose, uncompressed condition. The example in A compactor can then compact waste can be stored and / or transported to save space.

The invention enables a continuous disposal of used Web material, this also in particular thin films runs smoothly, so that disposal-related Downtimes can be avoided and changed accordingly the throughput of the web material processors Can increase facility.

A disposal facility suitable for carrying out the method has the first means of holding flat of a first web section, second holding means for flat Holding a second track section, which is preferably at a lateral distance from the first path section is arranged, and at least one with the holding means cooperating separator for severing the Web material in a lying between the web sections Intermediate section or separating section.

The first holding means and / or the second advantageously have Holding means at least one movable in the feed direction Pressure surface on which the web sections can be pressed flat are. In particular, the holding means can be endless circulating funding, such as a conveyor belt or Conveyor roller can be formed on which a longitudinal section of the Web material lies flat. It is possible that the Pressure surface is moved with the feed path speed, so that there is static friction between web material and pressure surface can build up. It is also possible to use the pressure surface with a higher speed or excess speed to move against the supplied material so that there is a slip between the pressure surface under the formation of sliding friction and material web results.

The pressure can be from that opposite the pressure surface Side, for example gentle on the material with brushes or similar. In a preferred embodiment are the holding means by a suction conveyor, in particular a suction roll is formed, the at least one at feeding speed or at a versus feed rate higher peripheral speed rotating conveyor element with an outer surface serving as a pressure surface, to the one the track sections and the intermediate section or separating section comprising the longitudinal section of the Web material is suction.

Although it is possible that an associated separator for example with the pressure surface in cutting engagement occurs, it is preferred if the pressure surface at least one that can be bridged or spanned by the web material, preferably transverse to the direction of movement recess having. A section can be in the area of the recess of the pressed web material without touching the The document should be floating and / or tense, what favors a reliable separation in this area.

A separating device preferably has at least one movable one Separator that is controlled so that it moved Web material in the area of the web material free hovering cut through cut. In particular can the separating device at least one with the rotating Funds synchronized, at least in scope a preferably oriented transversely to the circumferential direction Have separating element-carrying rotation element, such is arranged to the funding that a separator with combs or engages an associated recess. This can be done freely in the area of the recess by the separating element floating, possibly tensioned web material reliably and completely be severed. One especially for cutting up of embossed foil webs or other plastic foils Execution is characterized in that the separating member Cutting knife, especially with a serrated edge, through when the separating element engages in the web material punctiform perforations at first even with low contact pressure arise, possibly due to the internal stress of the web material supports itself in the event of further intrusion of the Increase cutting organ and eventually to form one continuous cut grow together.

Further features and details of the invention will become apparent from the following description of a preferred embodiment in conjunction with the drawing and the subclaims. Here, the individual features can be implemented individually or in combination in one embodiment. An embodiment of the invention is shown in the drawing. It shows:

Fig. 1

is a schematic side view of a rotary embossing machine with a continuously operating disposal device according to the invention.

1 schematically shows some elements of a transport device 1 for transporting an embossing foil web 2 in one Hot stamping rotary machine shown. This serves, for example for marking successive sheets or one Web made of paper, cardboard or plastic. It has an embossing mill 3 with a horizontal embossing cylinder 4 and an approximately same size, underlying impression cylinder 5, between which an embossing gap 6 is formed. The embossing cylinder 4 has at least one heatable embossing die along its circumference 7, through the one in the figure through the embossing gap 6 passing at a uniform web speed Material layer 8 an arranged on the embossing film 2 Embossing unit is embossed. The stamping foil web 2 has one Back 9 and a sensitive, a hot glue layer having front 10 and runs during one in the Figure shown embossing interval at the same speed and in same direction of movement 11 through the embossing gap 6, whereby the stamping unit under the influence of pressure and temperature is transferred to the material layer.

The device can with respect to the structure of the film transport device 1 of the rotary machine described in EP 0 718 099 correspond to their respective characteristics made the subject of this application by reference become. An embossing foil web is not based on one Unwind storage roll shown as a film stock through a film loop storage through a deflection roller 15 to a controllable by a drive motor 16 Control roller 17 out, the one the embossing film connected to the embossing gap 6 deflecting roller 18 is. On the feed side there is another control roller 17 'indicated that the plant for simultaneous processing several, preferably independently controllable, Embossed foil webs running parallel to one another is. The control roller 17 is designed as a suction roller and with respect to direction of rotation and / or speed of rotation controllable and controls the extent and direction of the film web movement through the embossing gap. She works with one not shown, the deflection roller downstream of the embossing nip 6 19 downstream pulling device together, the the maintenance of a suitable web tension Stamping foil web in the stamping gap area and further transport the used embossing foil web is used. This is through another, not shown film loop memory a continuously operating disposal facility 25 guided. In this embodiment, the web speed corresponds to with which the film web leaves the film store, the feed path speed at which the material of the Disposal device 25 is supplied.

The disposal device 25 comprises a speed-controllable one Motor 26 driven transport roller 27, a separating device 28 which interacts with this as well as one directed at the circumference of the suction roll, the Separator 28 downstream of the suction roll in the direction of rotation 29 Suction device 30.

The transport roller 27 is a vacuum roller or suction roller educated. It has a fixed roller core 31 um one along its circumference with radially through openings 32 provided roller sleeve 33 rotates. The roll core 31 is in the form of a cylinder sector and has one semi-cylindrical, open to the imaginary edge of the cylinder Recess 44. Roller core and roller sleeve are so against each other sealed that the formed in the region of the recess Cavity only in the area of the openings adjacent to it 32 to the cylindrical curved outer surface of the roller or is open to the environment. In this approx. 180 ° comprehensive Area is the suction roll 27 by the of the deflecting roller 19th Coming embossing foil web 2 running to the suction direction 30 entwined.

On the circumference of the roller sleeve 33 are two diametrically opposed to each other Roller axis of rotation opposite, parallel to the axis of rotation or groove-shaped aligned perpendicular to the direction of rotation 29 Recesses 34, 35 are provided. Only one can Recess or more than two, preferably in the circumferential direction recesses arranged at regular intervals are provided his. The schematically shown recesses have in Circumferential direction a width of about 0.5 cm, go in each case across the entire width of the roll sleeve and separate each a circumferential front portion 36 of the cylindrical Circumferential surface of the roller from a distance behind it rear section 37. Form the sections 36, 37 movable in the feed direction of the embossing foil web, cylindrical curved pressure surfaces on which the respectively lying Web sections with the suction fan running while building up Stiction can be pressed by between suction roll surface and web material in the region of the recess 44 a negative pressure is produced. This is in the area of the front section 36 first holding means and in the area of the rear Section 37 formed second holding means through which one overlying embossing foil sheet is held over a large area. A lying between the sections 36, 37, the recess 34 spanning intermediate section or separating section in contrast, hovers freely over the bottom of the recess 34 and can, if there is at least one in the area of the recess Suction opening is slight, while building up web tension are sucked into the area of the recess 34, preferably without touching the ground.

The separating device 28 cooperating with the suction roll 27 has a driven by the motor 26 with the roller sleeve 33rd synchronized rotating, roller-shaped rotating element 39, on its circumference a transverse to the circumferential direction Separating member 40 in the form of a cutting knife with serrated, is arranged radially outward cutting edge. The Suction roll 27 and the rotating knife carrier 39 of the separating device are arranged and synchronized with each other in this way driven that the separator 40 with each revolution of the Roller 39 alternately in one of the recesses 34, 35 approximately engages in the middle between the recess edges, but without touch the bottom of the recess.

The suction device 30 has one on a not shown Suction blower connected suction nozzle 45, the suction roller 27 facing suction opening 46 at a small radial distance from Circumferential surface of the roller sleeve 33 in a peripheral region of the Roller is arranged in which the suction openings 32 of the Recess 44 coming into the area of the opening covering Roll in the core 31. In this area by sealing the suction openings by vacuum caused holding force canceled so that easy lifting of the still lying on the peripheral surface and possibly still adhering Web material is guaranteed. It is alternative or additionally also possible, the openings 32 in the suction opening 46 opposite area from the inside with compressed air to act, so that an active blowing of the web material pieces the suction supports. The removed, crushed Web material can then be connected to the suction by means of a suitable air flow into a collecting container be promoted. Preferably joins the collection the waste is either continuous or batch compression to further reduce the Pack volume, for example by means of a baler.

The facility can operate according to the following procedure. In front A free end section starts at the embossing device the embossing foil web through the embossing gap and around the deflection roller 19 etc. except for those with effective suction openings Part of the suction roll 27 out where the free end portion is held securely by negative pressure. While running Device and roller sleeve rotating in direction 29 continuously fed web material is drawn in and arrives in each case on the peripheral section upstream of the separating device 28 37 in surface adhesion to the peripheral surface of the Sleeve. In the embodiment shown, the speed corresponds the sleeve surface in the circumferential direction of the feed path speed the film web 2, so that this under Build up static friction without slipping or taken away the suction roller 27 pulled from the upstream film storage becomes. As soon as a recess enters the contact area 47, in which the embossing foil web comes into tangential contact with the roller, the recess bridged by the stamping foil web under tension. The bridged area continues towards the separator 28 while the film web on the of the recess subsequent holding section is pulled up.

The serrated edge of the revolving separator 40 runs on a circular path that is in the area of the connecting line between the axes of rotation of the suction roll 27 and the rotating element 39 intersects with the cylindrical peripheral surface of the suction roll. When a spanned recess enters the In the area of the separating device, the separating element is initially set on the outside of the stretched film and is at further rotation up to the position shown in FIG. 1, where the cutting edge is directly to the axis of rotation of the suction roller shows, continuously further into the interior of the recess pressed. Beyond the maximum penetration depth shown the separating element runs through the opposite Rotation of the rotation elements 27, 39 out of range again the recess back.

When placing the serrated cutting knife 40 to the film in the region of the teeth tips along a straight line perpendicular to the direction of circulation 29 is arranged, quasi punctiform be immediately achieved great Aufpreßdrücke which cause a selective perforation of the film in the transverse direction, strongly push in the recess without it. The large-area adhesion of the film web on both sides of the recess reliably prevents web material from being drawn into the region of the recess during the cutting process. In the further course of the separating process, the saw teeth press further into the recess, with the perforations widening, until finally perforations grow together and the part of the material web, which is located in the circumferential direction in front of the recess and adheres flatly to the front section 36, from the part adhering to the rear pressing surface 37 Section replaces. The piece of web material which is then no longer connected to the rest of the embossing film web travels with its front region into the area of the suction opening 46 upon further rotation. At the same time, the suction openings covered by the front section are covered on the inside by the roller core 31, so that the suction effect is eliminated and the piece of material is removed can be suctioned off easily.

In the case of a device designed to produce longitudinal cuts, Not shown embodiment can do that in the described Embodiment formed by the suction roller 27 conveyor element along its circumference, but preferably several circumferential recesses running parallel to each other have in their area fixed or also rotating Separating organs, such as cutting knives, can intervene to Cut the material web into narrow longitudinal strips. The Longitudinal cuts can also be combined with separations in the transverse direction to create short web snippets that are special high packing density can be collected and compacted if necessary are.

While in the described embodiment, the peripheral speed the suction roll 27 is equal to the feed path speed is in another embodiment, not shown provided the peripheral speed of a revolving Conveying element at least temporarily, but preferably consistently greater than the feed path speed choose what distinguishes between material web and the corresponding Pressure surfaces not static friction, but sliding friction builds up or a slip occurs. This causes the conveyor element of the disposal facility is smooth and jerk-free, but is constantly pulling on the fed web material. It is if necessary, it is also possible for the web material to briefly counteract the direction of rotation of the conveying element in the direction of the embossing gap is withdrawn. The length of the pressure surface in the circumferential direction can be chosen appropriately so that a complete Slipping or pulling off the material web from the conveyor element is reliably prevented. Such a conveyor the disposal facility can with a Cross-sectional and / or longitudinal section separating device interact. Longitudinal cutters can be used particularly advantageously be, their fixed or moving, in particular rotating separators a separation of the web material largely independent of the prevailing Cause web speed of the web material fed to them can. In the case of cross cutters, it can be modified Execution form described for example so that a revolving separator with a peripheral speed of the suction conveyor deviating rotational speed revolves, which may depend on the actual Feed path speed can be controlled to prevent tearing or to prevent plucking of the web material to be cut or to minimize.

One with excess speed compared to the moving film web rotating conveyor, especially suction conveyor, the Disposal device can be a pulling device with slip drive form for the material web 2 that with the embossing gap upstream control roller 17 for continuous or discontinuous movement of the embossing foil web the embossing gap cooperates. This can be a separate one if necessary Traction device such as that used by the suction conveyor is formed with slip drive of EP 0 718 099, omitted. Also on one between the embossing gap and the disposal facility if applicable, film storage can be arranged to be dispensed with. In such embodiments, a Suction conveyors have a double function, on the one hand within the scope of the film accelerator for the right one Speed and direction of movement of the embossing foil web in the embossing gap and on the other hand as a holding means for the used embossing foil web during continuous disposal acts.

Disposal devices according to the invention also work for high throughput speeds of the web material and are both for cutting thicker, stiffer web material, such as paper or the like, but especially for reliable fragmentation of thin film material, excellent suitable. The created possibility of a trouble-free, continuous disposal of used web material allows appropriate facilities for processing of the web material without downtimes due to disposal to achieve higher performance.
