Definitions

  • the invention relates to a device for winding flat fabric or film webs by means of a rotatably drivable winding roller, in which a clamping device is used for tensioning the web to be wound, into which the web can be partially inserted through a longitudinal groove incorporated into the winding roller and after the creation of the Winding is detachable from the clamping device.
  • Winding rollers for receiving webs of fabric in order to compress them and thus to be able to transport them easily are known in the form of winding tubes made of metal or hard paper.
  • one end of the fabric is loosely wound onto the tube, which is usually rotated by hand, and the other end of the fabric therefore does not assume a defined position, since this is also not required for the transport of the wrap.
  • folds often form, so that a roll produced in this way cannot be used for further processing.
  • a longitudinally slotted winding roller which has clamping springs arranged as a clamping device in the inside of the roller on both sides of the longitudinal slot, into which the beginning of the material web to be wound inserted through the longitudinal slot can be clamped and pulled out after completion of the winding.
  • the clamping springs are formed in this known winding roller with a laterally protruding, flat lying U-shaped connecting strip. Due to the fastening of the clamping springs on both sides of the longitudinal slot of the winding roller, these connecting strips form an insertion slot for the initial region of the material web, the width of which is narrower than the material web.
  • this known winding roller is only suitable for material webs with an initial area adapted to the width of the insertion slot of the clamping springs. However, this is not the case with fabric or film webs.
  • a wrap-around roller in which the starting area of a material web can be clamped over the entire width, is known from US-A-38 63-857.
  • the winding roller is designed in several parts as an expansion roller. It consists of an expansion chamber inside an intermediate cylinder, which can be expanded or contracted by a corresponding compressed air supply. On the outer wall of the expansion chamber, mounting sockets for two outer loose shell parts are arranged through support holes through bores in the intermediate cylinder. The two shell parts and a third shell part firmly connected to the intermediate cylinder are kept at a distance from the intermediate cylinder with the interposition of a spacer.
  • Another support plate on the outer wall of the expansion chamber carries a pressure bar for the beginning of the material web to be inserted through a slot between a loose and the fixed shell part, which is clamped by compressed air supply into the expansion chamber on the inner wall of the fixed shell part, the loose shell parts following be pressed outside, so that the three shell parts complement each other to form a circular cylinder, on the outer surface of which the winding is formed.
  • This known winding roller is obviously very complicated.
  • a take-off device for the wound web is not available. The insertion into the slot should only be problem-free with stiff materials.
  • Another expansion winding roller known from DE-B-12 64 204 has an airbag surrounding a hollow cylindrical filler body inside a cylinder provided with radial openings, through the radial openings of which pressure bolts are connected to the airbag for supporting and tensioning the core of a paper roll or a roll stepping out of other material and falling backwards to remove the web wrap, the packing preventing excessive falling back.
  • This known winding roller is also constructed in a relatively complicated manner, there is no removal device for the finished web windings and there is also no clamping device for the initial region of a web to be wound.
  • DE-B-21 28 851 discloses a device for tensioning a winding tube with a drive device which has a tensioning head which is arranged on a shaft end and can be inserted into the winding tube with jaws that can be expanded against a return device.
  • the clamping head only serves to establish a drive connection between the driving shaft and the winding tube.
  • the object of the invention is therefore to provide a device for winding flat fabric or film webs, which is not only easy to transport as a winding in a processing system to the individual workstations, but also processes the edges thereof in the wound state, e.g. B. can be hemmed or welded, since the distance to the winding tube is always exactly adjustable.
  • it should be achieved that the winding is to be carried out without difficulty in a short time and that no wrinkles occur.
  • the removal of a roll from the winding roller should also be easy to accomplish.
  • the winding roller which is preferably supported on two support rollers arranged at a lateral distance from one another, is divided in two in length and one part is designed as an axially displaceable pull-off device which can be braced from the inside with a winding region of the web to be wound which projects beyond the other part is a cutout as a continuation of the longitudinal groove for the passage of a height-adjustable sword for partial insertion of the web in the clamping device.
  • the take-off device To remove the winding, it is also appropriate to form the take-off device from an axially adjustable clamping head provided with an insert piece which can be inserted into the winding roller and which can be clamped to the inner circumferential surface of the wick in the manner of a collet.
  • the clamping head should have a plurality of openings which preferably extend in the axial direction and in this an inflatable tube or the like should be provided. insert which can be deformed by pressure medium and emerges through the openings, by means of which the winding can be clamped with the clamping head. Furthermore, it is appropriate here that the deformable insert arranged in the clamping head is made of two inflatable parts held on both sides of the clearance, which are connected via a distributor chamber to a common pressure medium supply line.
  • the clamping device of the winding roller can be designed in different ways, namely by a slotted clamping sleeve inserted into it, which in the area of the longitudinal groove worked into the winding groove has inwardly angled resilient arms, by several slotted spring washers inserted into the winding roller, which are attached to one in the cage arranged and fastened in the area of the incorporated longitudinal groove with inwardly angled resilient arms or by two preferably angled, rotatably mounted and by spring force clamped against each other, which are arranged in the area of the longitudinal groove incorporated in the winding roller.
  • the clamping device of the winding roller can also consist of two inflatable tubes or the like arranged on both sides of the longitudinal groove worked into this. inserts which can be deformed by pressure medium. By means of the sword, part of the web to be wound can thus be inserted between the resilient arms of the clamping sleeve or the spring washers or the clamping strip or the inflatable tubes without difficulty.
  • the device designed according to the invention for winding flat fabric or film webs is not only simple in its structural design and thus economical to manufacture, but also versatile, reliable and easy to handle. Namely, if the web to be wound is tensioned with it by means of a clamping device arranged in the winding roller, it is possible to drive the winding roller at high speed during winding and thus to produce windings in a short time without wrinkles being formed. A double winding can also be carried out if the web to be wound is clamped approximately in the middle.
  • the fabric or film web is wrapped extremely tight.
  • their edges are brought into a constantly defined position after predetermined full and / or partial revolutions of the winding roller and can thus be processed in one or more workstations.
  • the transport of flat structures since they are compactly compacted in a small space, is made considerably easier, and guide means and installation space are also saved.
  • the windings produced by means of the device designed according to the invention are therefore versatile, especially since they can be quickly removed from the winding roller by means of the take-off device.
  • the device shown in FIG. 1 and designated 1 for winding a flat fabric or film web 2 consists of a rotationally drivable winding roller 11 and a clamping device 21 inserted therein, by means of which the web 2 can be connected with the central part 2 'or with one of the both end parts 2 "or 2" 'can be clamped.
  • the winding roller 11 is provided with a longitudinal groove 12 through which the part of the deflected web 2 in question can be inserted into the clamping device 21 with the aid of a height-adjustable sword 3.
  • the winding roller 11 is held on support rollers 13, which are assigned press rollers 14 and through which the web 2 is guided.
  • the clamping device 21 consists of a slotted clamping sleeve 22 which is arranged in the winding roller 11 and which has resilient arms 23 and 24 which are angled inwards in the region of the longitudinal groove 12.
  • the part 2 '- or one of the end parts 2 "or 2'" - is easily inserted between the resilient arms 23 and 24, so that tensioning of the web 2 with the winding roller 11 can be accomplished in a simple manner is.
  • the clamping device 31 arranged in the winding roller 11 consists of a plurality of spring rings 32 which are arranged at a lateral distance from one another and which also have resilient arms 33 and 34 which are angled inwards in the region of the longitudinal groove 12.
  • the spring rings 32 are fastened by means of rivets 36 or in a similar manner to a cage 35 which is connected to the winding roller 11 in a positionally oriented manner.
  • the respective part of the web to be clamped in the clamping device 31, in contrast to the clamping device 21, is thus not held over the entire length, but only in sections by the resilient arms 33 and 34, so that it can be removed again easily and with little effort.
  • FIG. 3 consists of two angularly shaped clamping strips 42 and 43 which are arranged in the region of the longitudinal groove 12 of the winding roller 11 and which are rotatably supported by means of bolts 44 and 45 on one or more retaining rings 46 arranged at a distance from one another. Due to the inwardly directed legs of the terminal block 42 and 43, the part of the web introduced into the winding roller 11 is pressed together and thus held in place, since a tension spring 47 or 48 acts on the outer leg, which is fastened to the retaining ring 46.
  • the clamping device 51 is formed from two inflatable tubes 52 and 53 which are inserted into the winding roller 11 on both sides of the longitudinal groove 12. Compressed air can be supplied to the tubes 52 and 53 in a controlled manner via nozzles 54 and 55, which are connected to a common pressure chamber 56, so that as soon as a part of the web to be tensioned is between them, these can be inflated.
  • the position resulting from the inflation of the tubes 52 and 53 is shown in broken lines in FIG. 4.
  • the compressed air is fed into the pressure chamber 56 via a pressure medium supply channel 57, which is incorporated into the bearing journal 4 of the winding roller 11, from a pressure medium source (not shown).
  • a pressure medium source not shown
  • a take-off device 61 is provided, which is shown in FIGS. 6 and 7 and consists of a clamping head 62 designed in the manner of a collet and having one end of the shorter one when the width of the winding roller 11 to be wound is connected and the winding roller 11 is expanded to approximately the width of the web to be wound 2 in order to obtain a winding part which can be gripped from the inside by the take-off device.
  • a deformable insert 64 is arranged, which is designed as an inflatable tube parts 65 and 66.
  • openings 63 extending in the axial direction are machined into the clamping head 62, from which, as shown in broken lines in FIG. 7, the hose parts 65 and 66 can emerge.
  • the tensioning head 62 is thus clamped to the winding so that it can be easily removed from the winding roller 11 by an axial displacement.
  • the clamped part of the wound web is released from the clamping device.
  • a channel 70 connected to a pressure medium source is connected to the pin 72 of the clamping head 62, which is rotatably mounted in a component 75 by means of a roller bearing 74 and on which the winding roller 11 is supported with the aid of an insert 71 inserted therein incorporated, via which pressure medium can be introduced into a collecting chamber 68, from which the hose parts 65 and 66 can flow via nozzles 69.
  • a schematically drawn servo device 73 For the axial displacement of the tensioning head 62 and for its rotation with respect to the winding roller 11 after removal of a winding, a schematically drawn servo device 73 is provided, by means of which after the end of a winding process the tensioning head 62 together with the firmly tensioned winding initially to the left in order to establish the connection between it and to loosen the winding roller 11, shifted and subsequently rotated relative to this in order to feed the winding to a work station, for example.
