Definitions

  • the present invention relates to a device for coupling and uncoupling heald frames to or from a shaft drive with a plurality of shaft rods, each with a coupling part on the side of the shaft and the shaft rods, a locking element which locks the coupling parts and a pivotable actuating device for the Bolt element is present, as well as a weaving machine with such a device.
  • EP-A-407 334 describes an actuating tool in which organs arranged parallel to one another and pivotable about a common axis of rotation open the couplings and shaft rod, the coupling parts being held in such a way that the heald frame can be changed automatically by means of a vertical movement.
  • This operating tool does not take into account the fact that the heald frames have different levels due to the preparation of the chain, which is a disadvantage.
  • the invention has for its object to provide a device of the type mentioned that aligns the coupling parts during coupling and uncoupling and holds its position so that a secure locking function is guaranteed.
  • a loom with a device according to claim 1 is characterized according to the invention by the features of claim 10.
  • the advantage for the weaving machine is that the shaft change process can be carried out automatically by the control device of the weaving machine or by means of a remote control device.
  • Figures 1 and 2 show the device together with a part of the shaft drive, which has an angle lever 1 and a shaft rod 2, which is articulated on the one hand on the angle lever 1 and on the other hand is connected to the receiving coupling part 3 with locking element 4 tension-resistant.
  • a coupling part 5 to be received is shown, which is attached to a heald frame, not shown.
  • a drive device with two identically designed drive units 7, 8 and two U-shaped brackets 9, 10 are arranged, which can be pivoted in opposite directions about parallel axes of rotation.
  • Each drive unit 7, 8 contains a linear motor 11 which is pivotally mounted in a holder 12 fastened to the frame 6, a fork 13 which is fastened to the piston rod 14 and two toothed segments 15 16 which are connected on the one hand in a rotationally fixed manner to the brackets 9, 10 and on the other hand are rotatably arranged on the frame 6 by means of holding members 17, 18, so that the toothed segments 15, 16 mesh with one another.
  • only one toothed segment 16 has to be connected to the linear motor 11, which in the present case takes place by means of a lever 19 which is rotatable with the fork 13 and is connected in a rotationally fixed manner to the holding member 17.
  • the brackets 9, 10 each have a section 21, 22 on the opposite edges of their base sections for receiving the receiving coupling part 3 or for actuating the locking element 4.
  • the section 22 on the base section is provided with a series of recesses 23 which are delimited by tooth-like projections 24 and into which the receiving coupling part 3 is arranged and secured laterally when the device is closed for the purpose of changing the shaft.
  • the device also has a Hal he 25 for the shaft rods 2.
  • This holder 25 contains a plurality of slots 26 into which the shaft rods 2 can be inserted.
  • the holder 25 is fastened to two levers 27, which on the one hand on the frame 6 with a bolt 28 is rotatably arranged and on the other hand is guided on the bracket 9 in drivers 29.
  • the slots 26 provided for receiving the shaft rods 2 in the holder 25 are delimited by elastically deformable wall sections which are provided with sections on the opening side, so that the gap opening width is smaller than the gap width.
  • Each slot 26 is designed such that the shaft rod 2 is movable within the slot 26, but prevents the shaft rod 2 from falling out of the slot.
  • the device described above 1 In normal weaving operation, the device described above 1 is in a rest position (FIG. 1). In this position, the device is secured against unintentional actuation, e.g. by mechanical locking of the drive device and / or electrical locking of the control device.
  • the weaving machine To change the heald frames, after a textile preparation e.g. Detach goods and warp remnants, etc., the weaving machine into a closed position, in which the shaft rods 2 assume the position shown in FIG. 2, moved and locked in this position.
  • a textile preparation e.g. Detach goods and warp remnants, etc.
  • the drive device 7, 8 is put into operation, as a result of which the brackets 9, 10 are pivoted in opposite directions to one another and are pivoted toward the shaft rods 2.
  • the locking element 4 is actuated and the receiving coupling part 3 is aligned, so that when the brackets 9, 10 are set, the locking of the coupling parts 3, 4 is released and the coupling parts 3, 5 are held in a stable position.
  • the device After the end of the shaft change process, the device is brought into the rest position, the shaft rods 2 not coupled to heald frames being brought into a parking position by the receiving part 25, in which the parked shaft rods 2 move up and down within the slots 26 of the receiving part 25 during normal weaving operation move off.
  • the receiving part 25 can be attached to the frame 6.
