Definitions

  • the invention relates to a drive device for the heald frames of a weaving machine, in which the transmission mechanism for the movement to the heald frames is articulated on the crossbeams of the heald frames running parallel to the healds.
  • the transmission mechanism consists of a linkage and tension elements which act on the crossbar of the shaft parallel to the longitudinal extension of the healds.
  • the parts of the boom are hooked onto the sides of the heald frame at the bottom and at the top of the crossbeams.
  • To remove the shafts from the weaving machine at least two hooks must be released.
  • the mechanism for reciprocating the shafts is interrupted.
  • the parts of the linkage must be individually held when coupling the heald and attached to the corresponding parts of the heald frame.
  • the spring retraction, which tensions the transmission mechanism must be relaxed while the shafts are removed from the weaving machine.
  • the process of changing the heald frames in a weaving machine with the described shaft drive device takes a relatively long time, depending on the number of handles to be carried out, as a result of which the operating efficiency of the weaving machine is reduced.
  • the object is achieved according to the invention in that the shafts on the crossbeams have shoulder elements, into which a toothing running in the direction of the back and forth movement of the shaft is incorporated, to which a portion of a tab in the transmission mechanism, which is likewise provided with counter-toothing, is pressed by means of a clamping element becomes.
  • the height of the shaft can be adjusted easily.
  • the interlocking grooves on the attachment element of the shaft and on the tab of the transmission linkage create a high surface pressure between the pressed parts and thus ensure good security against slipping of the shaft against the transmission mechanism even with a comparatively modest screwing force.
  • Connections a can by the tab of the transmission mechanism h lagmuffe be clamped, which ensures that the original stem position is found, after removal and re-insertion of a shaft in the weaving machine without any fuss.
  • the dobby 3 contains for each shaft a drive lever 6 pivotably mounted at 5, a pull clamp 7 articulated thereon, to which a pull rope 8 consisting of two sections 8a, 8b is clamped. This is guided via a fixed roller 9 to a point 11 at which it is coupled to the shaft 4.
  • the pull cable 8 is guided over a swing arm 13 pivotally mounted at 12, to which it is also attached.
  • a spring balancer 14 engages the bow rocker 13 at 15 and strives to pivot it clockwise in FIG. 1.
  • the shaft 4 in FIG. 1 is moved downward under the pulling force of the rapid section 8a; the shaft is moved upwards under the upward force of the cable section 8b generated by the spring balancer 14.
  • the shaft 4 contains two longitudinal beams 21, 22 which are connected to one another by transverse beams, of which only one is visible in FIG. 1 and is designated by 23.
  • a rail-shaped extension element 24 is attached, for. B. solved at 25.
  • the attachment element 24 has on the in Fig. 2 on the right-hand side a toothing 26 running parallel to the direction of movement 20, in which a counter toothing 27 running in the same direction engages a link 28 of the cable pull 8 which is also of rail-shaped design.
  • the link 28 has, on the side opposite the toothing 27, a toothing 31, again running parallel to the arrow 20, into which a counter toothing 32 of a clamping sleeve 33 engages.
  • the parts 31, 32 form an additional toothing.
  • the clamping sleeve 33 encloses the parts 24, 28 which are clamped together by means of a screw 35 with the interposition of a U-shaped pressure piece 36.
  • the traction cable 8 is connected with its two sections 8a, 8b at 38, 39 to the link 28. e.g. B. jammed.
  • a stop sleeve 41 is slidable and height-adjustable by means of a screw 42.
  • the shaft 4 can be coupled continuously along the toothing 27 to the rail-shaped member 28 of the cable 8, which forms the drive part for the shaft 4 which is moved back and forth by the transmission mechanism 6, 8, 13.
  • the coupling section 11 shown in FIGS. 1, 2 is provided on the opposite side, not shown, of the shaft in a corresponding manner, so that the shaft 4 is driven on the two crossbeams 23.
  • the invisible, left coupling part 11 is also driven by the dobby 3 via a cable 8c.
  • the extension element 24 with the crossbar 23 consists of one piece.
  • the direction of movement of the shaft 4 runs up and down in most weaving machines.
  • the bars 22 are generally made much longer than the crossbars 23, so that 21, 22 form the longitudinal bars and 23 the crossbars.
  • crossbeams 23 are attached to the two ends of the longitudinal beams 21, 22; with a large weaving width, crossbeams 23 (intermediate struts) can also be provided between them.
  • the transmission mechanism 6, 8, 28 engages those beams of the shafts 4 which run parallel to the direction of movement 20.
