Definitions

  • the present invention relates to a method for coupling and uncoupling heald frames to shaft rods according to the preamble of claim 1 and a weaving machine for carrying out the method.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a method for coupling and uncoupling heald frames to or from shaft rods, with which the heald frames automatically move to or from the shaft rods when manual or automatic harness change - Can be uncoupled, whereby a safe coupling process is guaranteed.
  • a loom for carrying out the method is characterized according to the invention by claims 2 to 4.
  • FIG. 1 shows part of an arrangement provided in a weaving machine with a heald frame 1, a heald frame 2, a heald lock 3 and an actuating device 4 for the heald lock in order to couple the heald frame to or from the heald frame.
  • the actuating device 4 contains a drive device with two identically designed drive units 5, only one of which is shown, and two U-shaped brackets 6, 7, which are drive-connected to the drive unit 5 via two toothed segments 8, 9 in order to pivot the brackets in opposite directions , as shown by the double arrows A and B.
  • This pivoting movement brings the shackles into or out of engagement with the shaft lock 3. It is pointed out that the number of drive devices can be designed depending on the width of the weaving machine
  • the shaft lock 3 contains a first coupling part 11, 31, which is attached to the heald frame 1 and is referred to below as the shaft-side coupling part, a second coupling part 12, 32, which is connected to the shaft rod 13 and is referred to below as the shaft-side coupling part, and a locking element (not shown), which locks the shaft-side and shaft-side coupling part.
  • the shaft-side coupling part 11 is formed in one piece and has a section 15 with a rectangular cross section and a flange 16 which is connected to the heald frame.
  • the shaft drive coupling part 12 has a body 17 with a recess for receiving the section of the shaft coupling part and two cover plates 18, 19, which are seen in the plane of the drawing at the front and rear of the body 17 e.g. are attached by welding to form a rectangular cavity for the positive reception of section 15.
  • the body 17 has a blind hole for receiving the rod 13 and is connected to it in a particularly advantageous manner by means of a screw connection (not shown).
  • a guide channel for the locking element 14 is provided in body 17.
  • a cutout 20 is formed with a bearing surface 21 for the locking element 14.
  • the locking element 14 has a rectangular basic shape and has on one narrow side a section 22 with an engagement surface 23 which can be brought into and out of engagement with the support surface 21 in the coupling part 11 on the shaft side and a through hole 24 (shown in dashed lines) in the region of the opposite narrow side.
  • the locking element 14 is connected to an arm of an arrangement consisting of two two-armed levers 25, specifically via an axis 26 which extends through the through hole 24 and is fastened to both levers 25. Between the sections of the lever 25 forming the other arm, one end of a compression spring 26 is held, which is held at the other end between the two cover plates 18, 19.
  • the shaft-side coupling part 11 When coupling the heald frame, the shaft-side coupling part 11 is first inserted into the shaft-side coupling part 12. Due to the opposite, opposite movement, the shaft-side coupling part 12 and the lever 25 are released, so that the lever 25 is pivoted due to the action of the compression spring 26 and moves the locking element 14 in the direction of the shaft-side coupling part. As a result of this displacement of the locking element 14, the engagement surface 23 is brought into contact with the support surface 21 in the coupling part 11 on the shaft side and a positive connection between the coupling part 11, 12 on the shaft side and on the shaft drive side is produced.
  • the shaft lock 4 shown in FIGS. 3A and 3B contains, analogously to the shaft lock according to FIGS. 2A and 2B, a shaft-side coupling part 31, which is fastened to the heald frame 1, a shaft-side coupling part 32, which is fastened to a rod 13, and a locking element 33, that locks the shaft-side and the shaft-drive side coupling part.
  • the shaft-side coupling part 31 has a coupling section 34 and a flange 35 for fastening the coupling part 31 to the heald frame 1.
  • an attachment 36 with two engagement surfaces 37, 38 which can be brought into operative connection with the shaft-side coupling part 31 and on the other hand a support surface 39 is formed which can be brought into active connection with the locking element 33.
  • the shaft drive coupling part 32 contains a body 40 which has a cutout 41 with two engagement surfaces 42, 43, which can be brought into operative connection with the shaft coupling part 31, and two cover plates 44, only one of which is shown.
  • the cover plates 44 are connected to the body 40 e.g. welded and form a lateral guide for the coupling section 34 of the shaft-side coupling part 31.
  • the shaft-side coupling part 32 is fastened to the rod 13, which is part of a flexible shaft rod.
  • the locking element 33 is a two-armed lever which is mounted on an axis 45 fastened in the cover plates 44.
  • One lever arm has a section 46 with an engagement surface 47 which can be brought into operative connection with the body 36 of the shaft-side coupling part 31, as will be described later.
  • On the other lever arm one end of a compression spring 48 is held, which is supported at the other end on the body 40 of the shaft drive coupling part 31 or is also held.
  • a stop part 49 is provided which is fastened in the cover plates.
