Definitions

  • the invention relates to a gripper for weft insertion in a rapier weaving machine, with a clamping hook for the weft thread and an associated clamping tongue which can be displaced in the longitudinal direction of the gripper under spring action in a gripper frame, a clamping tongue head and the one flank of the clamping hook being inclined to the longitudinal direction of the gripper.
  • the invention is based, one in particular to create improved grabs in this regard.
  • the invention consists in that the other clamping hook flank - in comparison to the inclined position of the one clamping hook flank - is inclined in the opposite direction to the longitudinal direction of the gripper and forms a guide for the clamping tongue head when the clamping tongue opens.
  • the rapier weaving machine according to FIG. 1, 2 contains a machine frame 1, a breast beam 11 and a central support 12.
  • the weft insertion mechanism contains two drive wheels 4 arranged on both sides of the machine, each for a flexible entry belt 5.
  • FIG. 1 only the catch side mechanism is shown .
  • a rapier 7 is attached to bring the weft thread 10 into the shed
  • a taker gripper Q is attached, through which the weft thread 10 in the middle of the shed is taken over by the taker gripper 6 and through the second half of the Shed is pulled.
  • the slave gripper 6 has a frame designated as a whole by 13, e.g. made of aluminum, which consists of a base plate 14 and two side walls 15, 16.
  • a clamping tongue 17 is slidably mounted (arrow 21).
  • the clamping tongue 17 engages with a fork-shaped part 22 a pin 18 fastened on the base plate 14 and continues to the left in FIG. 3 into a pull arm 24.
  • the clamping tongue 17 is thus pivotable about the pin 18 according to arrow 23.
  • the clamping tongue 17 has a clamping head 25, shown larger in FIG. 4.5 and attached to a connecting plate 50, for example made of hard metal, which - in the clamping position - below the effect of a compression spring 27 together with the entire clamping tongue 17 is pressed into a hook 28 attached to the frame 13.
  • the hook has a free end 29, the flank 31 of which is inclined relative to the longitudinal direction (longitudinal axis 32) of the gripper 6. With the hook flank 31, a correspondingly sloping flank 35 formed on the clamping head 25 cooperates.
  • flank 37 which is reversely oblique with respect to the axis 32 of the gripper 6 with respect to the axis 32 of the gripper 6 and with which a corresponding obliquely flank 38 of the clamping head 25 cooperates.
  • Lamella 47 is attached to the pull arm 24 of the clamping tongue 17 eccentrically at 48 with respect to the pin 18 (lever arm 40).
  • the clamping tongue 17 is shifted to the left and at the same time - due to the eccentric force effect by lamella 47 - is pivoted counterclockwise by a small amount.
  • the clamping head 25 arrives in the opening position 25a indicated by dashed lines in FIG. 3, where the flanks 37, 38 slide on one another.
  • Wedge 51 On the side wall 15 there is also a wedge 51 with an oblique flank 52 which cooperates with a corresponding oblique flank 53 formed on the clamping tongue 17. During the left shift of the clamping tongue 17, the pivoting movement about the pin 18 is supported by the wedge 51. Wedge 51 also forms a counter bearing with respect to the flank 37 of the hook 29, which prevents vibrations of the clamping tongue 17 during its left movement and the superposed pivoting by 18.
  • a pin 61 is fastened on the base plate 14 and cooperates with a curved slot 62 of the clamping tongue 17.
  • the wedge 51 is omitted.
  • the clamping head 25 is also under slide on each of the two flanks 37,38 and g shortest We and moved in a very short time in the opening position 25a.
  • the tongue 17 can then optionally also be made of an elastic material, e.g. Plastic.
  • the head 25 can then be held under a bias of the tongue 17 in the clamping position shown in FIG. 4.
  • the flanks 37, 38 slide on one another under the pretension so that at least the clamping head 25 of the tongue 17 experiences a pivoting movement with respect to the bearing point 18 (transverse movement to the longitudinal axis 32) in addition to the longitudinal movement.
  • the bringer gripper 24 can also be equipped with clamping parts which have inclined flanks to produce a swiveling movement superposed on the translatory pulling movement.
