Definitions

  • the invention relates to a method for coupling and uncoupling heald frames to or from a shaft drive with a plurality of drive trains in a weaving machine, each with a coupling part on the side of the shaft and the shaft drive in each drive train and with a coupling element that connects both coupling parts, a pivotable actuating tool for the coupling element being additionally provided.
  • the invention further relates to a weaving machine for performing the method.
  • German Offenlegungsschrift 30 06 363 (Egelhaaf) describes such a method, wherein two coupling elements on a coupling part of the shaft drive can be pushed apart by an eccentric if the heald shaft with its coupling part is to be inserted between both coupling elements. After the shaft-side coupling part has been inserted into the coupling part of the shaft drive, the eccentric is disengaged from the coupling elements so that they can engage with projections in corresponding recesses of the coupling part on the heald frame.
  • Embodiments with only a single coupling element are also described in the DOS mentioned.
  • the device has the disadvantage that shaft drive coupling part is very voluminous, since the coupling elements or the coupling element, the actuating tool and the coupling part of the heald frame must have space in its interior.
  • the coupling element is brought into engagement by means of the actuating tool when engaging in a pivoting movement from the outside against the coupling parts at the same time with support surfaces provided on the shaft-side and shaft drive-side coupling parts and when disengaging these engagement surfaces.
  • the weaving machine required to carry out the method is characterized in that the bearing point of the coupling element on the coupling part in question is arranged separately from the contact surfaces on the same coupling part, and that the coupling element has engagement surfaces in each case for the contact surfaces of the shaft-side coupling part and for the contact surfaces of the shaft-side coupling part , wherein these engagement surfaces are arranged separately from the bearing surfaces at the bearing point of the coupling element.
  • a pair of tabs 11, 11 ' is attached to the heald frame 1 above a support 15, which carry a bolt 12 on which the shaft-side coupling part 10 is located. It has a recess 10 'at the bottom and a pocket 14 with contact surfaces 14' and 14 ⁇ .
  • the coupling part 10 can be inserted vertically into the coupling element 3 with the heald frame 1 according to the direction of arrow A.
  • the coupling element consists of two Coupling wedges 31 and 31 ', which are held together by two cover plates 30 and 30'. In Figure 1, only the rear cover plate 30 can be seen, since the coupling element 3 is shown in section without a front cover plate 30 '.
  • the coupling wedges 30, 31 are fixedly connected to the cover plates 30, 30 ', for example by hump swelling at the connection points 32.
  • the plates 30 and 30' are circular, with segments outside the coupling wedges 31, 31 'being cut off, and have a central one Bore, which forms a bearing surface 27 on a bolt 23.
  • the bolt 23 sits in a bore of a projection 20 'on the shaft-side coupling part 20.
  • the bearing point 26 of the coupling element 3 on the lower coupling part 20 is thus the fulcrum of the coupling element 3. It can be brought into different positions by an actuating tool 5.
  • the actuating tool 5 has been pivoted counterclockwise in the direction of arrow C, the lower coupling part 20 being in the open position.
  • a bumper 21 which transmits the stroke movements of the shaft drive according to FIG. 5 to the shaft.
  • the coupling wedges 31 and 31 ' have engagement surfaces 35, 36 and 35', 36 'with which they are in engagement with contact surfaces 14', 14 ⁇ after retracting the upper coupling part 20. This is brought into the closed position by moving the actuating tool 5 according to arrow B.
  • FIG. 1 For a clearer illustration, the situation according to FIG. 1 is shown again in perspective in FIG. 2, only the rear plate 30 of the coupling element 3, which is congruent with the front plate 30 not shown, being visible. Likewise, only the rear tab 11, which is congruent with a front tab 11 'is drawn, which on the one hand on the carrier 15, the with the shaft 1 is connected, is attached, on the other hand carries the bolt 12.
  • FIG. 3 shows a side view of the arrangement, in particular the tabs 11 and 11 'can be seen, which carry the shaft-side coupling element 10, and the plates 30 and 30', which hold the coupling wedges 31 and 31 'together.
  • the whole arrangement is very slim, since up to about 20 heald frames have to be arranged next to each other in a weaving machine.
  • the actuating tool 5 is shown schematically in FIG. It consists essentially of a drive shaft 53, which is connected to a pneumatic actuator 55, a crank arm 54, which is rotatably connected to the drive shaft 53, and axes 52 and 52 ', which carry rollers 51, 51'.
  • the actuating tool 5 can be pivoted in the direction of the arrows B, C by means of the actuator 55.
  • the lines 56, 56 ' are used to supply compressed air.
  • the weaver After the shafts 1 according to FIG. 5 have been inserted into the weaving machine by a lifting device when changing the article in the weaving machine, the weaver only has to enter a command into the control device 6 of the weaving machine, not shown, so that the Actuator 55 pivots the actuating tool 5 in the closed position. All inserted shafts 1 are thus coupled to the bumpers 21 of the shaft drive 2. The bumpers 21 are connected via angle levers 22 to push rods 25 of the shaft drive, which in turn are actuated by the weaving machine's shaft machine, not shown.
