Definitions

  • the invention relates to a warping device with a winding support, a rotary drive, with which the winding support is rotationally driven, a bearing device for the winding support and a yarn sheet guiding device, which is movable along the winding support.
  • a warping device with a winding support, a rotary drive, with which the winding support is rotationally driven, a bearing device for the winding support and a yarn sheet guiding device, which is movable along the winding support.
  • Such a device is out GB-A-2 210 642 known.
  • Such a warping device is usually designed as a cone-sharpening device with a winding support, which is designed as a warping drum.
  • a warping device can perform a so-called Se ErasmusalschDC automatically.
  • Se Erasmusalsch a group of threads in the form of a so-called “band” or “ribbon” deducted from a gate and wound with the required length on the warping drum.
  • the yarn sheet guiding device moves the yarn sheet during each revolution of the warping drum by a predetermined amount to one end of the warping drum, so that a cone-shaped Structure of the winding results. This prevents falling on the free end of the winding threads.
  • the yarn sheet guide device is again moved to a starting position, in which the yarn sheet is wound on the circumference of the warping drum at the foot of the cone. The process begins again. There are so many tapes wound side by side, that the desired width of the chain is achieved.
  • the chain Following the skerry, i. generating the winding, the chain must be folded. For this purpose, it is unwound from the warping drum and wound on a warp beam with full width. Previously, the tapes have been severed at predetermined locations to provide the required number of individual threads for the warp.
  • the warp beam has end disks at its two axial ends which are intended to prevent the yarns from falling off the winding at the axial ends. Accordingly, it is necessary to wind the yarns from the beginning with the number needed later in the warp. If you want, for example, a chain with a thousand threads per meter, then you have a gate at a meter wide chain available that can accommodate a thousand coils. This is a relatively complicated procedure. Thus, at the beginning of a warping process, the thousand threads must be handled, for example guided by a warping rake and a cross-laying device. The larger the number of threads that must be handled individually, the longer the set-up time needed before producing a chain.
  • the invention has for its object to enable short production times when producing a chain.
  • the winding support is designed as a warp beam, which is detachably connected to the rotary drive and the bearing device and has at least one Kettbaumin.
  • a Kettbaumeinhebevorraum is provided.
  • the Kettbaumeinhebevorraum can lift the empty warp beam in the warping device and especially lift out the wound with the chain warp beam from the warping device. This facilitates handling.
  • a cross-cord storage is releasably connected to the warp beam.
  • automatic sectioning which can be performed with the present warping device, you have to draw cross-cords in the winding.
  • These cross cords serve to form a division cross, a sizing cross or the like.
  • the winding has been completed, i. so many ribbons have been wound up that the chain is available with the required width, then the cross-straps between the warp beam and the winding formed thereon and the thoroughschnur Boulevard can be severed. You then have the required cross cords in the chain, but can handle the warp tree in itself.
  • the cross-cord memory is rotatably connected to the rotary drive.
  • the cross-cord memory is driven at the same speed as the warp beam also.
  • the warp beam therefore does not have to transmit any drive power to the cross-cut storage. This minimizes the risk that the cross-straps may become confused at any point in the production process.
  • the Kettbaumin openings for performing cross-cords Preferably, the Kettbaumin openings for performing cross-cords.
  • the cross cords can then be fed at the radial position where they are needed later. This makes it easy to ensure that unacceptably high voltages are avoided on the cross-cords.
  • Openings in the warp beam are not critical, because the areas of the warp beam remaining between the openings reliably prevent threads on the warp beam from detaching and falling off the winding.
  • the warp beam disk has at least one guide, in which a cross hook is arranged.
  • the cross cords must be displaced parallel to the axis of the warp beam during the production of the warp, and once per wrapped tape once by the width of the ribbon. Since the cross cords are difficult to grasp, it is expedient to attach a cross cord to a cross hook. It is then possible to grasp the cross hook and, with the aid of the cross hook, to pull out the cross cord parallel to the axis of the warp beam, for example by the width of the ribbon.
  • At least one pliers attachment is provided with a parallel to the warp beam movable pliers.
  • the pliers can capture the cross hook and with the help of the cross hook the corresponding cross cord around the shift desired axial distance, so that the next ribbon can be wound up.
  • the warp beam disk has a conical bearing surface. If the Kettbaumin has a conical contact surface, then you can wrap the ribbon in the form of a cone, i. the winding then always has a conical end face. With the conical front side, the risk is low that individual threads fall down on the front side. This makes it easier to pull the chain later from the warp beam. This prevents unacceptably high stresses on the warp threads.
  • the warp beam on the warp beam in the axial direction can be fixed in different positions. You can then adjust the width of the chain to the desired needs. If a narrower chain is desired, then the Kettbaumectomy is shifted to the warp beam, for example, to a position at which remains at the finished chain at the two axial ends an approximately equal clearance. Other possibilities are conceivable.
  • Fig. 1 shows in highly schematized form a warping device 1 with a winding beam formed as a warp beam 2, are wound on the threads 3, which are subtracted from a gate 4.
  • the threads 3 are guided by a Stammlege issued 5 and then by a Shurriet 6, in which they are finally combined into a band 7.
  • the warp beam 2 is connected to a rotary drive 8.
  • the warp beam 2 at one axial end of a tree receptacle 9, which forms a non-rotatable engagement with the rotary drive 8 with a driver, not shown.
  • a further tree receptacle 10 which is mounted in an abutment 11.
  • the counter bearing 11 is displaceable in the direction of a double arrow 12, i. parallel to an axis 13 of the warp beam 2. This makes it possible to first bring the warp beam 2 at one end with its tree receptacle 9 into engagement with the rotary drive 8 and then cause a storage of the other end by the abutment 11.
  • a cross-cord memory 14 Rotationally connected to the rotary drive 8 is a cross-cord memory 14, in which a plurality of cross-cord coils 15 is arranged. From each cross cord coil 15, a cross cord 16 can be deducted. Each cross cord 16 is connected at its end remote from the cross cord coil 15 with a cross hook 17.
  • a pliers attachment 18 is provided, which has a pair of pliers 19 which is movable parallel to the axis 13. This movement can be realized, for example, by displacing the tong attachment 18 parallel to the axis 13.
  • the pliers 19 can grasp a cross hook 17 and displace it with the cross cord 16 fastened thereto, for example by the width of a ribbon 7.
  • the Schwarzensky 6 and the funnellege Nur 5 are movable together, for example via a carriage, not shown, which is driven by a ball screw 21. Also, the pliers attachment 18 can be driven accordingly, for example by a second, not shown ball screw.
  • Baumeinhebe nails 22 are provided at both axial ends of the warp beam 2, which can be used to lift the warp beam 2 in the warping device 1 and the fully wound warp beam 2 from the Scarify 1 warping device, as is indicated schematically by double arrows 23.
  • a Kettbaumefficiency 24 is disposed on the warp beam 2.
  • the warp beam 2 may for example be formed as a tube which is provided on its peripheral surface with an external thread 25.
  • the warp beam disk 24 may have a corresponding internal thread 26, so that the warp beam disk 24 can be positioned on the warp beam 2 in different axial positions.
  • a fastening device may be provided in a manner not shown, for example in the form of a lock nut which holds the Kettbaumefficiency 24 on the warp beam 2 in the desired position.
  • Alternatively or in addition to the thread pairing 25, 26 may also be provided a clamping device which holds the Kettbaumin 24 on the warp beam 2 in the desired position.
  • the Kettbaumefficiency 24 has a bearing surface 27 which is cone-shaped, ie it includes with the axis 13 of the warp beam an acute angle ⁇ .
  • This acute angle ⁇ is theoretically in the range of 1 to 89 °. Preferably, however, it is at most 45 ° and in a particularly preferred manner it is at most 20 ° or even only 15 °.
  • the presentation of the Fig. 2 is to be understood here purely schematically.
  • the Kettbaumefficiency 24 has, as shown in Fig. 3 can be seen, a plurality of openings 28, which are formed in the present embodiment as elongated, radially directed openings.
  • the openings 28 do not have to run strictly in the radial direction from the inside to the outside, but may also have a different course, if desired.
  • guides 29 for the cross hooks 17 and the cross cords 16 are provided. These guides 29 can be positioned and fixed in the radial direction at different locations, for example by means of a clamping shoe (not shown in detail). If one calls the cross-cords 16 as dividing means, then one can call the guides 29 also completely as "Teil worns-guides".
  • the guides 29 are used at the beginning of the warping process to receive and hold the cross hooks 17, so that the cross cords 16 can be attached to the cross hook 17 before the start of production.
  • the guides 29 are then positioned in the radial direction so that the cross hooks 17 lie in the radial direction at the desired location.
  • a guide 29 will be positioned radially as far inside as possible so that it is adjacent to the periphery of the warp beam 2.
  • Another guide 29 will be positioned radially further out, at a position corresponding to the desired diameter of the winding 20 formed on the warp beam 20.
  • a cross-cord 16 is guided, along which the ribbons 7 are cut later in order to obtain the desired beginnings of the filaments 3.
  • the warping device 1 works as follows:
  • the warp beam 2 is inserted into the warping device 1. If the warp beam 24 has not been previously set at the desired axial position, then it is then moved to the desired axial position.
  • the cross cords 16 are unwound from the cross cord coils 15 and connected to the cross hooks 17.
  • the first ribbon 7 is attached to the periphery of the warp beam 2 at a position adjacent to the warp beam 24.
  • the rotary drive 8 sets the warp beam 2 in rotation, the warp beam 2 pulls the yarns 3 out of the gate 4 and produces a winding which is initially formed only from a ribbon 7.
  • the Schwarzerriet 6 is displaced in each rotation of the warp beam 2 in the direction of the Kettbaummini 24, so that there is a winding 20 whose one end face is formed by an inner cone and the other, remote from the rotary drive 8 end face by an outer cone.
  • the cone angle here corresponds to the angle ⁇ .
  • the cross hooks 17 are pulled out by the pliers 19 by the width of a ribbon parallel to the axis 13.
  • the pliers attachment 18 can be moved.
  • the next ribbon 7 can be wound, which is wound in the same way as the first ribbon with the difference that The second ribbon can not create the contact surface 27 of the cone plate 24, but to the front side of the first coil. For this you can cut off the first ribbon and tap.
  • the beginning of the second ribbon is then glued to the warp beam 2. Alternatively, you can lead the ribbon down on the warp beam 2 and continue winding almost endlessly. In both cases, the crosses are still generated automatically.
