Definitions

  • the invention relates to a Device and method for picking up and holding Tableware elements, in particular slats for weaving machines in a warp threading machine.
  • the invention relates to an apparatus and a method to distribute these crockery elements to the arrangement supporting elements provided in a weaving machine.
  • Such slats are usually stored in large numbers stored and e.g. into a lamella separation device introduced for warp threading machines, such as this emerges from CH 687 027.
  • Characteristic of this The type of separation is the buckling or bulging of the Slats (see there Fig. 3) through which the front Slat in a central area as far from the second The slat is moved away so that it can be gripped in a simple manner can be.
  • Generic devices and methods - for distribution of slats used in weaving machines - are known for example from CH 682 577. These plants pick up the slats at a separation point and fasten them they - in a first step - on a so-called "Carousel” or a slat distribution module (see there Fig. 3 or 7), which holds the slats and a feed point transported where a thread through the eye of the Slat should be retracted. This happens, for example by pulling devices as described in CH 679 598 are. In a second step, the slats - together with the thread - to the distribution point transported and there on one or more supporting members, such as e.g. Contact rails, lined up.
  • supporting members such as e.g. Contact rails
  • the object of the present invention is a To propose a device or a method with which with the dishes, such as slats and the like, added and can be held and the jumping repeat can be done when distributing the slats.
  • FIG. 1 shows a warp threading machine. This exists from a base frame 1 and from various, in this arranged modules, which each form a functional module.
  • a warp beam carriage 2 In front of the base frame 1 is a warp beam carriage 2 with a recognizable on this arranged warp beam 3.
  • the Warp beam trolley 3 also contains a lifting device 4 for Holder of a frame 5 on which the warp threads KF are stretched are.
  • the warp beam carriage 2 with the warp beam 3 and the lifting device 4 to the so-called Upgraded side of the drawing machine and the Frame 5 is lifted up by the lifting device 4 and hung where he then occupies the position shown.
  • the frame 5 and the warp beam 3 are in the longitudinal direction of the Base frame 1 moved. With this shift the warp threads KF are guided past a thread separation stage 6 and separated and divided. After dividing up the warp threads are cut off and presented to a drawing needle 7, which is part of the so-called feed module forms.
  • a screen 8 can be seen next to the pull-in needle 7, which belongs to an operating station and for display of machine functions and machine malfunctions as well is used for data entry.
  • the control station is part of one so-called programming module and also includes an input level for manual entry of certain functions and processes.
  • the drawing machine is controlled by a Control module, which comprises a control computer and in one Control box 9 is arranged.
  • This control computer includes preferably an individual one for each functional module Module computer, which is controlled by the control computer and is monitored. To the main modules of a drawing machine In addition to the modules already mentioned, the strand, Slat and leaf module.
  • the thread separation stage 6, which the retracting needle 7 the to be retracted Warp threads KF presented and the trajectory of the Retractable needle 7, which is vertical to the plane of the clamped Warp threads KF determine a level, which the already mentioned upgrade side from the so-called downgrade side the pulling machine separates.
  • the so-called dishes can be on the disarming side (Strands, lamellas and leaf) with the drawn-in warp threads be removed.
  • the warp thread monitor slats LA are arranged behind these the healds LI and even further back the reed.
  • the slats are stacked in hand magazines and in feed rails 11 hanged.
  • the heald stacks are on these for separation to the separation point and the individual strands transported to the retracting needle 7 for pulling in the warp thread. After pulling in, the slats open the disarming side on lamella support rails 12.
  • the strands LI are lined up on rails 13 and on these automatically moved to a separation point. Thereon the strands are brought individually into their retracted position and after the warp thread has been drawn in to the corresponding Heald frames 14 distributed on the dismantling side.
  • the reed is also gradually drawn on the pull-in needle moved past, the corresponding leaf tooth for the feed is opened.
  • Weave WB (partially shown to the right of the heald frames 14) also on the dismantling side.
  • a so-called crockery trolley 15 is on the dismantling side intended. This is attached together with the attached Support elements - the slat support rails 12, heald frames 14 and a holder for the reed - in the illustrated Position inserted in the base frame and carries after the Feed the dishes with the warp threads.
  • the functions described are distributed over several modules, which represent practically autonomous machines or systems, which are controlled by the common control computer.
  • the main modules of the drawing machine already mentioned are preferably built up again in a modular manner and include Supply modules.
  • This modular structure is in the Swiss patent No. CH 679 871, the disclosure of which is hereby described explicit reference is made.

  • the pull-in needle comprises 7, which forms the main component of the feed module Gripper belt 16 and a clamp gripper carried by this 17.
  • the pull-in needle 7 is in one stroke direction (arrow P) channel-like guide 18 which extends from the frame 5 in straight direction to an arcuate end portion 19 extends.
  • the guide 18 passes through the drawing machine and is in the area of tableware elements (slats LA, strands LI) and the reed WB each interrupted to feed the crockery elements to the feed position and their further transport after moving in until handover (arrow S) to the support members (lamella support rails 12 or heald frames 14) and the drawing of the warp threads into the reed WB (the so-called leaf pricking).
  • a slat distribution module is used on the respective supporting elements LD or strand distribution HD. Both sub-modules In principle, LD and HD perform the same functions by offering them sequentially or step by step Take over the crockery elements to the feed point transport and to a Transport the transfer point where the transfer to the Supporting elements, i.e. the lamella contact rails 12 or heald frames 14 takes place.
  • Figure 3 shows a partial spatial view of a plant 20 for Picking up, holding and distributing slats as a sub-module in a warp threading machine.
  • One about an axis of rotation 21 movably arranged head 22 for receiving, holding and Transfer of crockery elements, especially slats for weaving machines, comprises four devices 23, which are symmetrical are arranged to the axis of rotation 21.
  • Each of the four shown devices for receiving and holding crockery elements, especially of lamellas for weaving machines has two opposing holding surfaces 24, 25.
  • a first holding surface 24 is provided with a first piston 26 connected, which is movably arranged in a first cylinder 28 is.

Because of the much lower mass of the second Piston 27 flips (in the direction of the small arrows, 4B) forward faster than that first pistons formed simultaneously as second cylinder 29 26. This means that the lamella LA first of the Device 23 captured and only then from the separation position Will get removed.
  • Alignment of the lamella is made possible by positioning lug 32 and a guide nose 39 causes both on the first cylinder 28 are attached.
  • the restoring force of the spring 31 causes that the positioning lug 32 with its bridge of the nose 41, which represents an inclined plane, at the bottom of the contact rail slot 42 attacks and the slat down pulls - when the first cylinder is fully retracted, the position of the slat is also correct.
  • the move the lamella LA between the holding surfaces 24, 25 is possible because the restoring force exerted by the spring 31 'is smaller is that of the spring 31.
  • the shifting happens controlled because practically at the same time as the positioning nose 32 also the guide lug 39 between the longitudinal webs 40 engages in the contact rail slot 42, so that practical only one shift of the lamella in parallel can be done down.
  • the rotating head 22 is rotated by 90 °, so that the grasped Slat in its retracted position or at the retraction point 51 is transported. Because the turret 22 four comprises the same devices 23, the next opened holding device 37 (corresponding to FIG. 4A) placed on the next - now also bent - slat. If the lamella is positioned at the retraction point 51, a warp thread is drawn through the eye 38 of the slat LA.
  • the slat is during the pulling in and also during the further transports to the transfer point 52 between safely the two holding surfaces 24, 25 and with the two lugs 32, 39 held between the longitudinal webs 40.
  • Transport to Transfer point 52 is again done by a quarter turn of the head 22 about the axis of rotation 21.
  • the lamella LA At the transfer point is the lamella LA by a transport hook 34, which on a Distribution carriage 33 is arranged, on which the holding device 37 of the device 23 can be opened can.
  • the transport hook 34 is through the distribution carriage 33 moved out of the holding device 37 in the direction of the arrow and transported until the slat reaches a predetermined one Hand over the supporting element with the help of an ejector can be.
  • the fourth position which a device for gradual rotation around the axis 21 can occupy, is referred to as the drop position 53.
  • the drop position 53 So can be slats used by one for this purpose Control device (not shown) checked for its shape and - e.g. because of too big a deformation - for be found unsuitable for further use in this Thrown into a container (not shown) become.
  • a turret 22 with four devices 23 is then a preferred form of training, because at everyone of the four defined positions - separating 50, retracting 51, Transfer 52 and drop 53 - at the same time a device 23 is located. But it can also be a rotary head 22 provided with three, two or even only one device 23 be without giving up this possibility of dropping must become.
