Definitions

  • the invention relates to a method and an apparatus for pulling warp threads into dishware a weaving machine with a drawing-in organ.
  • Such a method and such a device are known for example from CH 682 577 and WO92 / 05303 known.
  • the device shown has a needle-shaped pull-in member, that starting from a starting position behind the reed, over a long way to Warp thread layer is moved to where it takes over a warp thread. Pulls on the way back the pulling-in element has a warp thread through a lamella, a strand and the reed, with larger gaps between the warp thread layer and the lamella, the lamella and to cross the strand and the strand and the reed. In these spaces special guides are arranged for the laterally flexible pull-in element.
  • modules for the provision of empty ones and for the distribution with warp threads Strands and slats are provided, with the modules, for example, circumferential drivers exhibit.
  • the object of the invention is therefore a device of the type mentioned, with the high feed rates without the known, associated disadvantages.
  • the warp threads are no longer through the pull-in member of picked up at a remote location, but from a transport device to a transfer point brought and picked up there by the pull-in organ.
  • the transfer point is as possible close to the reed and the trajectories of the harness organs such as strands and slats, are passed so close to the reed that the pull-in element, for example a Retractable needle, only a relatively short stroke movement and with this all the dishes traverses.
  • the space between, for example, the Warp thread layer with the stretched warp threads and the reed is only partially to be crossed by the pull-in device.
  • the warp threads are preferably staggered from the warp thread layer to the Introduce organ.
  • the movement paths of the tableware should be in a space of approx. 60 to 100 mm width can be introduced, so that the path or stroke of the retractor on a Can limit the length from 120 to 200 mm, which also depends on the length of a loop, which the warp thread forms in order to hang in the pull-in member.
  • FIG. 1 shows warp threads, possibly not shown in their full length here, in the are known and stretched together in a frame not shown here form a warp thread layer 1.
  • a warp thread 2 is shown which with its one end 3 in the region of a movement path 4 of transport clamps 8, 8 ' a transport device 5, so that this end 3 is gripped by a transport clamp can be.
  • Such a device for presentation is, for example, from WO 92/08830 known with which the end 3 of a warp thread are brought into the position shown can.
  • a transport device 5 is also known with which Difference that the known transport device is arranged vertically while in in this case essentially horizontally, or in the plane of the lifting movement of the pull-in member to be ordered.
  • the transport device 5 is designed such that it warps like For example, pull a warp thread 6 around a deflection pin 7 and in a certain one Release position.
  • the transport device 5 consists essentially of a rotating organ, such as a chain, with attached clamping organs 8, 8 '.
  • For opening and closing the clamping members 8, 8 ', for example, are known per se but scenes or curves not shown here in the areas of recording and Dispensing points 37, 38 are provided.
  • the warp thread 6 is prepared at a transfer point 36 so that it forms a loop and can be gripped by a pull-in member 9.
  • the Retractable organ 9 move a little further from the position shown to warp thread 6, so that it jumps into the recess 10.
  • the return stroke of the pull-in device 9 begin.
  • a drive 11 is provided, for example as Crank drive or can be designed as a linear motor, etc.
  • With an arrow 12 is the stroke movement of the retractor 9 indicated. Upstream of the drive 11 is a known reed 13, which is also understood here as a dish organ.
  • Guide rails 14 and 15 are arranged in a plane 14, 15, which is at a short distance to the reed 13 runs.
  • the guide rails 14, 15 serve dishware, here especially strands 16, 17 as upper and lower guides. Because the strands are two different Can have training, they are in a known manner, after training prepared separately on separate guide rails 14a, 14b and 15a, 15b. With at Known conveyor devices, the strands are taken in by the strand 17 Position moved. Since the strands are very flexible and movable, they can be arranged locally Guide 18 are made sure that the eye 19 is aligned so that it forms a passage for the pull-in member 9 and can receive a warp thread.
  • the warp threads are conveyed on to the warp threads and to a circulating distribution element 20 issued, for example, short sections 20a, 20b, 20c, etc. of guide rails has, which are spaced from one another, for example on a rotating chain are the distances between shafts 21 correspond to each other.
  • the chain around here is here represented, for example, by the dash-dotted line 20e.
  • the drive of the distribution element 20 takes place in cycles, so that there is always time available during the strands on the shafts 21 can be delivered.
  • a conveyor belt can also be used take on the task in question.
  • devices known per se can be used for transporting the strands from the sections 20a to 20d on the individual shafts.
  • Another distribution element is for guiding the strands on the lower side arranged and designed exactly according to the distribution member 20 and also in terms of movement synchronized with it.
  • the two distribution members 20 thus move essentially in a vertical plane to the shafts 21.
  • Such Carriers 29 are in a manner known per se, for example on a conveyor device, such as attached to a circulating chain, which in a channel 30, of which only one Piece is shown, circulates and is guided. Is in the position shown for the slats 24 to 27 it is envisaged that these should pass to the lamella carrier 31.
  • a conveyor is already known for example from WO 92/05303, but with a trajectory, which has a different course.
  • One warp thread after the other is presented from the warp thread layer 1 so that one end 3 gets into the movement path 4 of the terminals 8 of the transport device 5, from where the The warp thread is pulled into the position of the warp thread 6 in a first movement. This happens at a first relatively slow speed, which is made possible by the fact that the next following warp thread 6a already staggered from the transport device 5 is detected before the warp thread 6 arrives at a transfer point 36 is.
  • the staggered warp threads together form a plane 39 which is used for the lifting movement 12 of the Retraction organ runs approximately parallel and is preferably horizontal.
  • tableware elements are provided, for example a strand 17 and a Lamella 23 in the position shown and the reed 13 with the following opening in the no warp thread has been drawn in yet.
  • the tableware intended for retraction have Paths of movement 22 which cross the lifting movement of the pull-in member.
  • the trajectories run in the area of the pull-in member 9 directly next to one another and at least approximately parallel.
  • the crockery elements 13, 17, 23 remain in for retraction a position such that the retractor 9, the lifting movement 13 through the dishes can run through. So that the warp thread 6 with a second movement drawn in and delivered to the subsequent holding member 35, which holds the warp thread 6 and can consist, for example, of a suction nozzle.
  • This second movement takes place with a speed that is preferably a multiple of the first speed of the warp thread in the transport device 5.
  • a speed that is preferably a multiple of the first speed of the warp thread in the transport device 5.
  • the tableware organs are then moved on and distributed, for example in cycles, with which the pull-in member 6 can be synchronized.
  • the strands are fed to the shafts 21 and targeted to individual Shafts distributed. To do this, they stay during different times or for a different time Number of clock steps on the distribution element 20.
  • the control of such distributions is on known and therefore not shown here.
  • the through the known conveyor Slats 24-27 which are further moved along the movement path 22 are also known Delivered to the disk carrier 31. These movements result in a relative movement between the drawn-in warp thread 32 and the tableware elements, so that for example the strands and the slats slide along the warp thread 32 in the opposite direction Direction to feed movement. Because of the slow movements but this can be done easily and without damaging the warp thread.
