Definitions

  • the present invention relates to a shedding device for a weaving machine, in particular a jacquard machine, with two rods connected at one end to the heald, which can be moved between an upper and lower position, with the rods associated with flexible holding elements held at one end in a holder, in order to hold the flexible rods Hold rods in an end position, wherein the associated rods and holding elements are provided at the mutually facing ends with complementary sections which can be brought into engagement with one another, and with an electromagnet which has a double T-shaped core with differently wide boundary flange parts and the holding elements are held on the holder such that an air gap is present between a flange part and the holding elements in order to deflect the holding elements against one another and to bring the rods and holding elements assigned to one another into and out of engagement.
  • a shedding device for a jacquard machine contains two rods which are moved back and forth by assigned knives, are connected at one end to a strand guided over the pulley, and at the other end have means for holding the rods in one position, a holding device which can be brought into and out of engagement with the means on the rods and a control device for bringing the rods into and out of engagement with the holding device.
  • the advantages of the present invention are essentially to be seen in the fact that by adjusting the air gap between the narrower flange part and the anchor part, the tightening force to be applied can be kept considerably lower, and therefore a relatively low supply voltage is required to excite the electromagnet and that the function of the Only one holding element is decisive, namely that which is assigned to the rod moving in the direction of the electromagnet.
  • the holding element is made of stainless spring steel, when the holding element is prestressed, in such a way that it has a restoring force with an egg in the deflected state nem setpoint that is matched to the holding force of the electromagnet, and when the holder is provided with two stop elements.
  • the movement of the holding elements away from the electromagnet can be limited and, on the other hand, the vibrations that occur when the holding elements are reset can also be damped in an advantageous manner, as a result of which perfect functioning can be ensured.
  • the shedding device contains two rods 1 which are arranged at a distance from one another and can be moved up and down by assigned knives 2.
  • the rods 1 are connected in a known manner at one end to the strand 3, which is guided via the block and tackle 4 which produces the connection to the warp threads.
  • the rods 1 are provided with a hook 5 and guided in a guide device 6a, 6b.
  • the rods 1 are guided on both sides by guide pieces in order to prevent them from being deflected when the rods 1 are displaced in the direction of the electromagnet 10.
  • a holding element 7 is assigned to each rod 1.
  • the holding elements 7 are cast at a distance which is substantially equal to the distance between the rods 1, at one end in a holder 8 made of plastic and at the other, the free end with an opening 9 into which the hook 5 of the corresponding rod 1 can intervene.
  • An electromagnet 10 is arranged between the holding elements 7 and consists of an I-shaped core 11 with rectangular flange parts 12, 13 of different widths and a winding 14. The electromagnet is attached to the holder 8 so that the narrower flange part 13 is closer to the free end of the holding elements 7.
  • the surfaces 18, 19 of the flange parts 12, 13 facing the anchor parts 15 are formed lying in one plane, so that the anchor parts 15 can be placed on the surfaces 19 of the flange parts 12.
  • a stop 23 can also be provided, which is formed on the holder 8, as can be seen from FIG. 1.
  • Two stop elements 20 are provided on the holder 8, which form two mutually opposite stop surfaces in order to limit the movement of the holding elements 7 in the direction away from the electromagnet 10.
  • the stainless steel spring element 7 is mounted under pretension, so that the holding element 7 in the deflected state has a restoring force that is matched to the holding force of the electromagnet 10 and in the reset state fits snugly against the stop surfaces of the stop elements 20.
  • FIG. 2 shows the operating state in which the knife 2 shown on the left in FIG. 2 is already slightly raised and the knife 2 shown on the right is correspondingly slightly lowered.
  • the rod 2 and the associated holding element 7 are in contact with one another in this position, as a result of which the holding element 7 has already been deflected.
  • This deflection of the holding element 7 continues until the rod 1 has reached the upper position, as shown in FIG. 3.
  • the air gap between the armature part 15 and the surface 18 of the narrower flange part 13 is set to a predetermined value and the knife 2 is now lowered.
  • the hook 5 on the rod 2 will engage in the opening 9 on the holding element 7 when the knife 2 is lowered, and the rod 2 will be held in its position, although the knife is further lowered, as shown in FIG. 4 is shown.
  • the armature part 15 is pulled by the magnetic field against the surface 18 of the narrower flange part 13.
  • the anchor part 15 bears against the surfaces 19 of the two flange parts 12, while the film 22 bears against the surface 18 of the narrower flange part 13 or the holding element 7 against the stop 23.
  • the lowering rod 15 can now engage with its hook 5 in the opening 9 of the holding element 7 and is thus lowered into the other end position.
  • the other holding element 7 is not deflected, even when the electromagnet 10 is energized. In this case, this only takes place when this holding element 7 the associated rod (not shown) has been deflected such that the air gap between the surfaces of the flange parts 13 and the anchor part 15 has the predetermined value.
  • Fig. 7 shows a modified embodiment of the holding element 7.
  • a projection 21 is formed next to the opening 9, which comes into contact with the hook 5 when the rod 1 is lifted. This allows the air gap to be set to a smaller value. The magnetic field to be generated by the electromagnet can then be further reduced.
