Definitions

  • the invention relates to a shedding device for textile machines, in particular weaving machines, with counter-rotating lifting knives and hook elements which can be taken from them in a hooking position and which are connected in pairs by means of loops, and with rollers running in the loops acting on the shaft pull or harness pull of the textile machine and with stationary electromagnets acting on the hooking elements and controllable via program carriers.
  • the object of the invention is to remedy the disadvantages of the devices described, to create a shedding device of the type mentioned at the beginning, in which the magnetic force for the locking position does not have to act via an air gap, and which nevertheless requires few parts.
  • the hooking elements can each be supported with a support foot in a support bar which is stationary at the level of the sub-position of the hooking elements, and an electromagnet is arranged between hooking elements which are connected via a loop and are associated with one another at the level of their sub-position, and in that the hooking elements are arranged pivotably in their sub-compartment position between a contact position against the electromagnet and a stop forming the hooking position.
  • the hooking element makes the lifting movement and on the other hand can be pivoted into the hooking position without the magnetic force having to act via an air gap.
  • the support foot is arranged outside the traction line between the holding device and the connecting member in such a way that the hooking element is pivoted into the hooking position by the shaft or harness pull.
  • the pivoting movement of the hooking element into the hooking position is thus applied without additional devices, such as springs or the like, by the force of the harness pull.
  • the arrangement can also be designed in such a way that the hooking element is pivoted by the shaft or harness in the opposite direction, that is to say in the direction of the electromagnet.
  • the hooking element has a main body with a hook device molded on one end and a support leg molded on the other end, and a connecting element formed between them, with a tongue-like design. It is advantageous that not only a pivoting movement of the hooking element can take place through the spring tongue-like connecting element, but the spring action of the spring tongue-like connecting element also has the positive effect that the movement of the hooking element into the hooking position is thereby increased.
  • the hooking element is made in one piece from plastic and has a magnet armature on the side facing the electromagnet in the sub-compartment position. It is advantageous that both when hooking in with the lifting knife, which is generally made of metal, and when bracing against the support bar, which is preferably made of metal, there is a contact between plastic and metal, which enables lubrication-free operation. On the other hand, this configuration enables the hooking element to be easily manufactured in an injection molding process without the need for post-processing.
  • the required magnetic armature can, for example, be injected during the manufacture of the hooking element or can also be clipped on, glued or fastened in some other way.
  • the hooking elements have projections protruding into the movement path of the lifting knives in their hooking position, and the lifting knives have sliding surfaces on their counter hooks, so that when the sliding surfaces come into contact with the projections the hooking elements are pivoted into one of the pivot positions, preferably into the contact position against the electromagnet.
  • the hooking elements can be brought close to the electromagnet, so that the magnet does not have to overcome an air gap for the holding process, so that the electromagnets can be designed with low attraction forces.
  • the shedding device has lifting knives 1, 2 and 3 which can be moved up and down by means of devices which are not shown in detail.
  • the lifting knives 1 and 2 are shown in the position of their bottom dead center of the lifting movement, while the lifting knife 3 is drawn in the position of the top dead center of the lifting movement.
  • the device also has hooking elements 4, which are drawn in various possible positions.
  • the hooking elements 4 shown on the far right and left of the drawing are pivoted and each attracted to an electromagnet 5. The pivoting takes place inevitably by the action of the lifting knife 1 and 2.
  • a 4 'designated hooking element has been moved by the lifting knife 3 to the top dead center. As can be seen, the hooking element 4 'is hooked into a hook of the knife 3.
  • the further shown hooking element 4 ⁇ is drawn in a position not pivoted against the electromagnet 5.
  • the hooking elements 4 are each made in one piece from plastic and have a main body 6 with a hook device 7 formed on one end and a support foot 8 molded on the other end. Between the hooking element 7 and the support foot 8, a spring tongue-like connecting element 9 is formed, which ends at its lower end, for example in a snap hook 10.
  • the connecting elements 9 can be connected, for example, by means of the snap hooks with loops 11, in which rollers 12 run, on which harness cables 13 are attached, for example.
  • the hooking element 4 has a magnet armature 14 on the side facing the respective electromagnet 5 in the sub-compartment position.
  • the electromagnets 5 are each arranged in a stationary manner in the device. They are supplied and controlled with electrical energy via schematically illustrated lines and schematically illustrated electronic components 16.
  • the groove-like recesses 18 are designed so that the hooking elements 4 with their support feet 8 in the position not pivoted against the magnets rest against the flank of the recess forming a stop 22, and that the opposite flank of the groove-like recess in the lower region of the curve of the support foot is adapted and opens in the upper area like a gap or like a game, so that a pivoting movement into the contact position against the magnet is possible.
  • Such a pivoting movement takes place - as already mentioned - by the downwardly moving lifting knife 1, 2 or 3.
  • the hooking elements 4 point to this projections 19 projecting into the movement path of the lifting knives.
  • the lifting knives 1, 2, 3 are also provided with sliding surfaces 21 on their counter hooks. When the lifting knife comes into contact with a hooking element, the projections 19 and the sliding surfaces 21 touch, and the hooking elements are thereby pivoted into the contact position against the respective electromagnet 5, in which the hooking elements 4 with their magnet armatures 14 rest against the electromagnet 5 without an air gap , so that there is no air gap to be overcome for locking the hooking elements by the electromagnet for the magnetic forces.
  • the spring tongue-like connecting element 9 of the hooking elements 4 is in each case in the direction of the traction line, as for example a consideration of the lifting knife 3 and the hooking element 4 'shows.
  • the support foot 8 of the hooking elements is arranged outside this traction line. This has the effect that the hooking element assumes the hooking position due to the shaft or harness pull.
