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 a pawl which can be coupled into the groove and is arranged on a cam rotatably mounted on the drive shaft, and with a tab of a crank rod which surrounds the cam for the drive to the shafts and at least one control lever which is movable in the path of the pawl and disengages them and which can be pivoted back and forth by a circuit board which can be coupled into a lifting knife drive.
  • the spring-loaded board is pivoted against the spring action by a drive rod, after which it is moved back under the action of the spring. During this back and forth movement, it may or may not be coupled with a lifting knife, depending on whether it is released by the armature of an associated electromagnet or not.
  • the clutch arrangement is relatively complicated and requires several springs. The drive parts come unsprung onto the circuit board to be coupled with the lifting knife or to be locked by the armature.
  • the invention has for its object to provide a particularly improved arrangement in this regard.
  • the invention consists in a reciprocating movement of a drive, on the one hand connected to the circuit board and on the other hand to a program control device, which carries two pivotable levers which are pulled by a spring against a central stop and between which a driver part of the drive projects.
  • the lifting part can be used in a sensible manner for the sprung drive of the board and on the other hand for sprung scanning of the position of the program control device. It is possible to get by with only a single spring, which means that the circuit board can be held in the non-positive coupling position with the lifting knife and the lifting part can be held in the non-positive scanning position on the program control device.
  • the frictional connection begins under low pressure, which is automatically increased by the spring moved with the lifting part.
  • the parts can thus be brought into the operative position with particular care and can be held resiliently in this operative position. You can also get by with very few parts.
  • 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 or rocker 7. This is articulated at 8 on a transmission linkage 9, via which the back and forth movement of the tab 7, which arises according to arrow 11, is transmitted to an associated shaft of a weaving machine.
  • the entire parts 1, 6, 7 form the so-called eccentric machine for driving and controlling all the heald frames of the loom.
  • 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 board 23 has a fork-shaped part 26 which forms a slot 27.
  • the pin 28 of an arm 31 of a three-armed lifting element 31, 32, 33 engages in this.
  • the lifting element can be moved up and down according to arrow 34 in FIG. 1.
  • the arm 32 carries at 35, 36 pivotally mounted, by a so-called center spring tension spring 37 held together, forming a slot 38 lever (overload lever) 41, 42.
  • the arm 32 of the lifting element carries a pin 44, which in the slot 38 between the Lever 41, 42 protrudes.
  • a pin 45 protrudes into the slot 38, which is attached to a drive lever 48 which can be pivoted back and forth according to arrow 46 by 47.
  • the lever 48 executes a full up and down stroke during operation, while the shaft 1 only rotates by 180 ° (double stroke method).
  • the program control device for engaging and disengaging the pawl 5 is controlled by a stationary electromagnet 51 is formed, which is able to attract an armature 53 which can be pivoted by 52.
  • the armature 53 works with the probe arm 33 of the lifting element 31 to 33.
  • the mode of action is as follows. If the heald frame belonging to the shown rocker 7 is to be moved alternately up and down during weaving operation, the pawl 5 must remain engaged in the drive shaft 1, as shown in FIG. 1. For this purpose, the control levers 14 to 17 must be in the ineffective position shown in FIG. 1 when the pawl 5 runs with its free end 61 under one of the hooks 18 of the control levers.
  • the armature 53 must not be attracted by the electromagnet 51, but must be in the pivoted-out blocking position shown in FIGS. 1 and 2 ( Effective position) remain.
  • the magnet 51 receives no current from the associated voltage source, it remains unexcited.
  • the spring 37 stretches so that the distance between the levers 41, 42 is increased.
  • the force generated by the drive lever 48 is directed in the position according to FIG. 2 via the spring 37 to the lower lever 42, which transmits the force via the pin 44 to the lifting part 32, so that the latter is shown in FIG. 2 under spring action Locked position and thus the arm 33 is held in a resilient, non-positive contact on the armature 53.
  • the lifting knife 25 returns to the right position shown in FIG. 2, which corresponds to the position according to FIG. 1.
  • the control levers 14 to 17 are thus in turn in the pivoted, ineffective position, pawl 5 remains engaged.
  • the lifting knife 25 runs from the right position shown in FIG. 1 to the left to its left reversing position, in which there is 23 clearance between the lifting knife and the offset 63 of the circuit board.
  • the board 23 is also moved to the left until the movement is limited by the two control levers 14, 15 and 16, 17 at the stop 54. These levers are now in the operative position 14a, 15a or 16a, 17a shown in FIG. 3.
  • the electromagnet 51 is energized so that the armature 53 is pivoted into the left, ineffective position 53a shown in FIG. 3.
  • the lifting part 31 to 33 is moved into the upper position according to FIG. 3 while keeping the smallest distance of the levers 41, 42. Arm 33 now has the position 33b, which is made possible by the ineffective position 53a of the armature 53 and in which the arm 33 stands next to the armature 53.
  • the movement generated by the lever 48 or the driving force is directed via the pin 45 onto the lever 41, from which the force becomes effect directed via the spring 37 to the dragged lever 42, which in turn moves the lifting part 31-33 upwards via the driving pin 44.
  • the board 23 temporarily comes into the effective range of the lifting knife 25, but is then immediately lifted back into the disengaging position 23a according to FIG. 3 moved back.
  • the lifting knife is thus unable to move the board 23 in FIG. 3 to the right and to move the control levers 14 to 17 into an ineffective position.
  • Jack 5 and the associated heald shaft remain in the previous rest position.
  • the spring 37 ensures that the parts 41, 42, 31 to 33 are taken along by the pin 45 during upward and downward movement, keeping the smallest distance between the levers 41, 42, as long as there is no obstacle in their path of movement. There is a constant readiness to over-tension the spring 37 as soon as the upward or downward movement of the parts is blocked or limited, for example by the armature 53 or the lifting knife 35.
  • One and the same spring 37 is used for frictional entrainment when the parts move up and down. A particularly safe mode of operation is thus achieved with a minimal outlay on parts. It is particularly important that spring 37 is not attached to a fixed part of the area, but is moved together with the lifting part 31 to 33 while being attached to the two levers 41, 42.
  • control parts 31 to 33, 37, 23 to be moved to have a relatively small mass due to the relatively small number of these control parts, so that the control movements can take place with particularly high acceleration. This is advantageous in order to achieve high machine speeds.
  • the relatively high force of the spring 60 holding the parts 1, 5 in the coupling position need not be overcome by movements and forces on the part of the control parts 31 to 33, 37, 23.
