Definitions

  • the invention relates to a coupling arrangement for controlling the shafts of a weaving machine, with an intermittently rotating drive shaft having at least one groove and an engaging pawl which can be coupled into the groove and is arranged on a cam rotatably mounted on the drive shaft and with at least one pawl which can be moved in the path of the pawl. they disengage the control lever, which can be pivoted from a lifting knife drive and is pulled by a spring against a stationary stop.
  • the invention has for its object to provide a particularly improved arrangement in this regard.
  • the arrangement according to the invention makes it possible for the control lever to be under particularly strong spring force when it hits the stationary stop.
  • the force of the return spring which is relatively weak in this position, can be supplemented by the force of the additional spring. This prevents or dampens vibrations when the control lever is knocked open. Also, the control lever cannot be moved from the operative position due to machine vibrations during operation. The disengagement of the pawl of the clutch arrangement corresponding to this position can therefore be carried out particularly reliably.
  • a drive shaft 1 which is set in rotation by 180 ° from the main shaft of the weaving machine in each case, contains two grooves 2, into which the nose 3 of a coupling pawl 5 pivotably mounted at 4 and acting under the action of a tension spring 60 can engage.
  • the pawl 5 is mounted on an eccentric 6 rotatably mounted on shaft 1, which is enclosed by a tab 7.
  • This is articulated at 8 to a transmission linkage 9, via which the back and forth movement of the tab 7, which arises in accordance with arrow 11, is transmitted to an associated shaft of a weaving machine.
  • On wave 1 there are a whole number, e.g. B. six to twelve of the drive parts 6, 7 shown in Fig. 1, namely an eccentric 6 and a tab 7 for each shaft of the loom.
  • the entire parts 1, 6, 7 form the so-called eccentric machine for driving and controlling all heald frames Weaving machine.
  • the shafts are moved in a high or low position according to a binding program for the warp threads.
  • a plate 23 is pivotally mounted at 22, which can be coupled with a reciprocating knife 25 moved back and forth according to arrow 24.
  • the lifting knife 25 is fastened on a two-armed drive lever 27, 28 which can be pivoted back and forth by 26.
  • the arm 28 contains a slot 31 in which a roller 30, which acts under the action of a tension spring 32 and extends over the entire length of the drive shaft 1 and thus detects all control levers 16, 17 arranged next to one another, is displaceably arranged.
  • the spring 32 is attached to the arm 28 at 33 at the other end.
  • the mode of action is as follows.
  • the rotary movement of the shaft 1 according to arrow 66 is transmitted via the pawl 5 to the eccentric 6, so that the rocker 7 and the linkage 9 are moved back and forth according to arrow 11 and the associated heald frame is alternately moved from the high position to the low position and back.
  • the circuit board 23 is in engagement with the lifting knife 25, by means of which the movement of the lifting knife in FIG. 1 also moves to the right against the action of the spring 55 to the right.
  • the two control levers 14 to 17 move into the ineffective position shown in FIG. 1, in which the end 61 of the pawl 5 can pass under the two hooks 18 of the control levers 14 to 17 without being gripped by them.
  • a program control device For the purpose of stopping the heald frame in the high shed or in the shed position, a program control device, not shown, pawl 23 at the end of a left stroke of the lifting knife 25 lifts it from the coupling position in FIG. 1 into the ineffective, upper position 23a (FIG. 2), in which it is out of engagement with the lifting knife 25. Shortly before the arm 17 runs onto the stop 54, the roller 30 lies against the arm 16. When the lever 27, 28 moves further according to arrow 40, the arm 28 also continues to run in the counterclockwise direction, so that the roller 30 moves away from the Sole 41 of the slot 31 lifts up while simultaneously tensioning the tension spring 32. The position according to FIG. 2 is created.
