Definitions

  • the invention relates to a device for changing the harness of a weaving machine with at least two support columns arranged on a chassis, with the support columns vertically movable and preferably horizontally fold-out arms and with one on the Arms arranged device for the transfer of Heald frames, which transfer device two at a distance arranged from each other by at least one crossbar interconnected, with guide rails for the heald frames and at least two on one connected to the boundary plates Cross beams spaced from each other, support elements pivotable relative to the cross member for receiving and handing over the heald frames.
  • Such a weaving machine is known from EP-A-0 620 304.
  • the chassis When changing the harness, the chassis is in aligned a certain position to the loom and then the handover or takeover by lowering initiated the transfer device.
  • the heald frames are inside the weaving machine in plastic guides guided precisely. This means that too the side of the transfer device has a high geometric Precision must be observed to the heald frames Insert smoothly into the guides of the weaving machine to be able to.
  • weaving mills are common Own looms with different weaving widths, for the loading of different article change vehicles so far had to be used.
  • the invention is based on the object the well-known exchange device for harness to improve the type specified at the beginning, that a smooth article change even with different Weaving widths is possible.
  • the solution according to the invention is based on the idea the distance between the boundary plates adjustable to design, so that with one and the same article change vehicle Looms with different Web width can be loaded.
  • the distance adjustment the boundary plates are made motorized.
  • the crossbeam and the crossbeam are made of each at least two telescopic parts that can be telescoped simultaneously composed, in a preferred embodiment of the invention, the telescopic parts of the Crossbeam and the crossmember expediently by each a screw drive are connected to each other simultaneously are drivable.
  • the one that extends through the cross member, adjustable in length together with the crossbeam, preferably telescopic synchronous shaft includes.
  • the mobile article changing device shown in the drawing is for handing over a warp beam and one Weaving tableware determined on a weaving machine.
  • the article changing device contains a chassis 10 with a device 12 for transferring a warp beam 14, two support columns 16, two mounted on the chassis 10 Boom 18, which together on the support columns 16 around Dimension h can be moved up and down and horizontally at the joints 20 can be folded out, a carrier 22 on the Joints 24 is articulated to the arms 18 and one Device 26 for the transfer of heald frames, not shown to the loom.
  • the heald frame handover 26 comprises two spaced apart interconnected by a crossbar 28, with essentially vertically aligned guide rails 30 boundary plates provided for the heald frames 32 and two on the cross member 22 at a distance arranged from each other, opposite the cross member lever-like pivotable support elements 34 for receiving and handover of the heald frames.
  • the boundary plates 32 are via a synchronous drive, not shown in detail interconnected to any level differences the limit plates 32 when putting on to compensate for a machine-fixed support.
  • the synchronous drive includes a synchronous shaft 38, the extends through the cross member 22 and via which the cross member 22 can be moved indirectly and vertically is connected to the boundary plates 32.
  • Both the cross member 28 and the cross member 22 are made of two simultaneously telescopic telescopic parts 28 ', 28 "or 22', 22" assembled.
  • the Telescopic parts are 38.40 each by means of a stepper motor and a screw drive 42, 44 can be displaced relative to one another.
  • the stepper motors 38, 40 are activated simultaneously via a common control device.
  • the synchronous shaft 36 is telescopic educated. With these measures it is achieved that the clear distance between the boundary plates 32 the length of the heald frames can be adjusted, so that one and the same article changer for loading used by weaving machines with different weaving widths can be.
  • the invention relates to a device for changing the Weaving harness of a weaving machine.
  • the device has two support columns 16 arranged on a chassis, two horizontally movable on the support columns and horizontal fold-out arms 18 and one on the arms 18 arranged device 26 for the transfer of Heald frames.
  • the heald frame transfer device 26 comprises two spaced apart, by at least one crossbar 28 connected to each other, provided with guide rails 30 for the heald frames Boundary plates 32 two on one with the boundary plates 32 connected cross member 22 at a distance arranged opposite one another, opposite the cross member 22 pivotable support elements 34 for receiving and transferring of the heald frames.
  • the crossbar 28 and the cross member 22 from two simultaneously telescopic telescopic parts (28 ', 28 "; 22', 22") assembled.
