Definitions

  • the invention relates to a shaft drive device for a weaving machine, with a mechanism for the transmission of the drive movement which causes the shafts containing the longitudinal and transverse beams to move back and forth.
  • the transmission mechanism consists of a linkage which engages the lower longitudinal beam of the shaft.
  • the linkage contains e.g. two climbing boards moved up and down, at the upper ends of which a hook is attached, which engages around a matching stud attached to the lower longitudinal beam of the shaft. So there is a positive coupling of the transmission mechanism to the shaft on the lower longitudinal beam of the shaft.
  • the shaft For the transmission of the driving forces introduced into the longitudinal beams, the shaft must be provided with particularly strong longitudinal beams, as a result of which a correspondingly high mass has to be moved back and forth.
  • This type of drive of 400 min-1 and more is not suitable due to the masses of the shafts that have to be continuously accelerated and braked again.
  • the invention has for its object to provide a shaft drive device which is particularly improved in this regard.
  • the invention consists in the fact that the transmission mechanism is coupled in each case to the crossbar of the shafts and drive motion and driving force are introduced into the crossbar of the shaft.
  • the driving and braking force of the transmission mechanism are constantly parallel to the longitudinal extension of the crossbeam during operation.
  • the beam of the shaft, namely the crossbar, which absorbs the driving force is not subjected to bending and can be designed to be relatively weak.
  • the entire shaft is relatively light, which is why the device is particularly suitable for high speeds, e.g. suitable for weaving machines with air intake.
  • the drive forces on the part of the transmission mechanism e.g. using a toothing running parallel to the crossbeam of the shank can be introduced non-positively into the crossbeam. Joints between the transmission mechanism and the shaft beam can be largely avoided.
  • the longitudinal beams of the shaft can also be built relatively lightly, so that they only provide a relatively small proportion of the total mass of the shaft.
  • a shaft drive machine 3 e.g. Eccentric or card shaft machine
  • 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 cross beams, of which in Fig. 1 only one is visible and designated 23.
  • a rail-shaped extension element 24 is fastened to the crossbar 23, for example detached 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 pull cable 8 is connected with its two sections 8a, 8b at 38.39 to the link 28, e.g. 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 Fig. 1,2 is on the opposite side, not shown, of the shaft is provided 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 much longer than the cross bars 23, so that 21, 22 form the longitudinal bars and 23 the cross bars.
  • crossbeams 23 are attached to the two ends of the longitudinal beams 21, 22; if the weaving width is large, 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.
