Definitions

  • This invention relates to a yarn remover device for removing unused yarn from a yarn holder of the type used to 5 supply yarn to a weaving loom.
  • Yarn holders have yarn wound thereon and are known as “cheeses” and “tubes", and yarns are unwound from the holders in order to meet the demand of a weaving loom.
  • a piece has been woven, it is often the case that at 0 least some of the holders still retain a substantial portion of unused yarn wound thereon.
  • the partly spent holders are often transferred to specialist firms who 5 recover the yarn from the holders and then sell the waste yarn in bulk to customers for re-processing.
  • the recovery of the waste yarn is an unsophisticated process, which involves cutting the yarn in order to release it from the tube, rather than by unwinding 0 the yarn.
  • the tubes are often made from rigid plastics material, such as PVC, and frequently the surface of the tube becomes so damaged during removal of the waste yarn by cutting with a knife that the tubes are not normally _ considered to be suitable for re-use. 5
  • This problem arises with yarns in general, but particularly in relation to carpet-making yarns where there is a considerable market, particularly an export market, for the supply of recovered unused yarns.
  • a yarn 5 remover device for removing unused yarn from a yarn holder.
  • the device comprising: a frame; first and second upright supports mounted on the frame and spaced apart from each other by a distance corresponding to the length of the yarn holder; a guide adapted to receive and to guide downward movement of the ends of a stack of yarn holders; a power operated device cooperable with the first upright support and having an actuator head which is linearly reciprocable between a -retracted position and an advanced position, the actuator head being engageable with an adjacent end of a lowermost holder of a stack of holders in the guide when in the retracted position; an opening formed in the second upright and generally in alignment with the actuator head, the opening being of such a size as to allow the adjacent end of the holder to pass therethrough when the opposite end of the holder is engaged and is driven linearly by the actuator head towards the second upright; and, a yarn stripper device adjacent to said opening which is operable to strip the unused yarn from each holder and to permit the stripped holder
  • a yarn remover device is particularly suitable for use in removing unused yarn from cylindrical yarn holders of rigid plastics material, in which case the yarn stripper device conveniently may be formed by the edge region which defines the periphery of the entrance to the opening through which the holder is driven.
  • the guide is formed by a pair of aligned guide tracks formed one in each of the upright supports, and each adapted to receive and to guide a respective set of yarn holder ends.
  • the power operated device preferably comprises a fluid pressure operated device, and conveniently is formed by a pneumatic ram having a piston rod with said actuator head on a projecting end of the rod.
  • the actuator head may be shaped so as to be engageable partly within the interior of the adjacent end of the cylindrical yarn holder and partly against the radially extending annular end face of the holder.
  • a stack of partly used yarn holders may be stacked in the guide tracks, and then they descend automatically under gravity as, in turn, the lowermost holder in the stack is engaged by the actuator head and is driven towards the stripper device which removes the yarn and allows the stripped holder to pass out of the device for subsequent re-use.
  • the stripped-off yarn then falls under gravity into a suitable collection device, and then can be sold in bulk form to customers.
  • the device may also be used to strip yarn from generally conical yarn holders of the type which are frequently used with weaving looms.
  • the device may be arranged so that the radially narrower end of each conical holder is engageable by the actuator head, whereas the radially larger end of each conical holder is located adjacent to said opening in the second upright.
  • the yarn stripper device may comprise a spring biased stripper device which is biased radially inwardly of the outer surface of the conical holder, so as to apply a radially inwardly acting stripping force on the outside surface of the conical holder as the latter is displaced axially through the opening. This then enables the stripper device to remove the yarn from the conical holder despite the radially narrowing profile presented by the holder as it moves axially through the opening.
  • the yarn stripper device takes the form of a power-operated set of jaws which are movable towards and 5 away from a stripping position adjacent to the opening in the second upright.
  • the jaws are preferably carried on the ends of levers which are pivotally mounted on the second upright, and which are power operated by any suitable means, such as pneumatic rams.
  • Each jaw may be mounted for generally horizontal guided movement towards and away from the stripping position, and therefore define a larger stripping opening (upstream of"the opening in the second upright), and thereby hold back the yarn on the holder while the latter 5 is pushed through the opening in the second upright.
  • the jaws are robustly constructed so as to withstand the yarn stripping forces applied thereon.
  • a travelling cradle is mounted on the device, so as to co-operate with the second upright, in 0 order to withdraw a tube after yarn has been stripped from the tube by the power-operated set of jaws.
  • the power-operated device in the form of a piston driven actuated head, is movable towards the jaws in order to _ drive the tube between the jaws while the latter grip the 5 outer periphery thereof in order to strip yarn therefrom, but the movement of the actuator head only takes place at least partly up to the jaws, and the travelling cradle - therefore is able to carry out final withdrawal movement of the tube.
  • the travelling cradle is preferably pneumatically operated for movement generally along the axis of the tube, the cradle being operated automatically in timed sequence with the operation of the actuator head.
  • an arrangement of one or more jets is provided in the region of the jaws, such jets directing compressed air towards the surface of the tube in order to facilitate stripping of yarn therefrom.
  • Pneumatic air jets are the preferred arrangement, in that there will normally 5 be readily available a suitable supply of compressed air in order to operate the various pneumatically powered components of the machine.
  • a robust guard 0 arrangement be provided which extends over and at least partly around the tube and the path of travel of the actuator head. The purpose of this is that, in the event of improper engagement taking place between the actuator head and the tube end, which might be liable to cause the 5 tube to be driven upwardly, the guard is able to hold the tube captive within its confines, and therefore not to cause any personal injury to the operative.

  • the device 10 comprises a frame 11, first 0 and second uprights 12 and 13 which are mounted on the frame 11, and which are spaced apart from each other by a distance 15 which corresponds generally with the-length of the yarn holder which is to undergo yarn stripping.
  • a pair of aligned guide tracks 16 are formed one in 5 each of the upright supports 12 and 13, and are adapted to receive and to guide downward movement of the ends of a stack of yarn holders.
  • FIG 1 there is only shown a lowermost yarn holder 17 at a stripping station at a lower end of a guide ;track 16, but it should be understood that a 0 stack of similar yarn holders 17 may be arranged above the illustrated yarn holder with the ends of the holders received by the guide tracks 16.
  • the yarn holder 17 shown in Figure 1 is a generally _ cylindrical tube made of rigid plastics material such as 5 rigid PVC tube, and has a partly .used package of yarn 18 wound therearound.
  • the yarn holder 17 is shown at an intermediate position during a yarn stripping operation.
  • a power operated device 19 cooperates with the first 0 upright support 12 and has an actuator head 20 which is linearly reciprocable between a retracted position and an advanced position with respect to a lower end of the guide track 16 in the first support 12.
  • the actuator head 20 is shown at an intermediate position between the fully 5 retracted position and the fully advanced position, and is shaped so as to be engageable partly within the adjacent end 21 of the tube 17, and partly against the radially extending annular end face of the tube end 21.
  • the actuator head 20 When the actuator head 20 is in the retracted position, it will be 5 withdrawn within the confines of the first upright support 12, so as to allow the lowermost tube 17 of a stack of tubes to descend to a stripping station in horizontal alignment with the retracted actuator head 20.
  • An opening 22 is formed in the second upright support 0 13 at a lower end of the guide track in the second support, and generally in horizontal alignment with the actuator head 20.
