Definitions

  • the invention relates to a method for separating textile surfaces from a stack and it also relates to an apparatus for performing the method.
  • the ribbed edges are needled on a comb with their last knitted course, i.e. H. the loop of each stitch in the last knitted course hangs on a needle.
  • the needles of the comb are put together with the knitting needles of the knitting machine and the stitches are slipped onto them. The knitting machine then continues knitting from this transferred row of stitches.
  • the rib edges on the transfer rakes are transferred to all knitting lines of the machine at the knitting needles.
  • Transferring the ribbed edges from the rake to the transfer rake of the machine is a manual task that takes a relatively long time. Automation of the edge handover has so far failed because there was no method for separating the rib edges on the opening rake, which allowed only the front rib edge of a stack of edges to be gripped and transferred to the transfer rake.
  • the difficulty in separating the rib edges needled as a stack on a rake consists essentially in the fact that the free edges of the rib edges are largely undefined in their position, i. H. they can be wavy, fold in one direction, the rib edges overlap like scales, and the corners of the rib edges can retract.
  • These shortcomings mentioned hinder the separation from the free edge, since no cutting edge can be inserted between the rib edges.
  • the separation from the rake side cannot be carried out insofar as the edges are too close together, which makes it difficult to grasp only one edge with a separation comb.
  • the object of the invention is to provide, with regard to automation, a mechanical and functionally reliable method for separating textile surfaces from a stack and a device for carrying out the method.
  • Rib edges 1 for the production of knitwear on flat knitting machines are needled as a stack on needles 2 of a push-up rake 2a.
  • the needles 2 have a U-shaped cross section and the open side faces away from the rib edges.
  • the tips of the needles 2 of the push-up rake 2a are overlapped with the tips of the needles 3 of a transfer rake 3a of the flat-knitting machine, the tips of the respective needles dipping into the U-shaped pocket of the opposing needles, so that the stitch surrounding the needle shaft is pushed over by one Needle on the other becomes possible.
  • the boards 4 are provided with leading edges 5 and 5a and with an open space 6 which extends from them and is open at the edge. On the circuit boards 4 there is also a lancing tip 7 formed by the leading edge 5 and the boundary edge of the free space 6.
  • the small width of the free space ensures that only the foremost rib edge 1 of the stack bulges into the free space 6 and thus a single rib edge 1 is always received by the piercing tips 7 of the plates 4.
  • the pushing needles 2 are separated from the transfer needles 3 and by means of a deflecting element 9, which can be a bar, a rod or a tube provided with a row of nozzles, the transferred rib edge 1 is folded away from the needles 3 of the transfer rake 3a prevent jamming on the needles 3 of the transmission rake 3a.
  • a deflecting element 9 which can be a bar, a rod or a tube provided with a row of nozzles
  • the last rib edge of a stack would hardly have any spring travel when resting against a fixed stop.
  • This is necessary in order to be able to offer the rib edge 1 relatively evenly to the piercing tips 7 of the circuit board 4 over its entire length.
  • the rib edges 1 have slightly thickened vertical edge areas due to their manufacturing process, which, in the absence of spring travel, leads to the plates 4 pressing into the edge via this edge area, while this pressing is not ensured in the central zone.
  • the stop 8, on which the stack of rib edges 1 is supported is formed from an elastic material, into which the thickened edges of the rib edge 1 are somewhat pressed.
  • FIG. 4 shows a transfer vehicle which can be moved via rollers 11 and tracks 12 and can be positioned in front of the individual knitting points of a flat-knitting machine arranged in a row.
  • a magazine 13 for receiving the pushing rake 2a.
  • the magazine 13 can pivot between a starting position and a transfer position for bringing together the needles 2 of the opening rake 2a and the needles 3 of the transmission rake 3a.
  • the magazine is preferably equipped with two diametrically arranged brackets 14, 15 with associated clamping elements, which are used alternately by a rotary movement about an axis 16.
  • the two levers 17 and 18 for generating the movement of the plates 5 about pivot points 19 and 20 are actuated by two independent drives, not shown.
  • the invention is not limited to the separation of rib edges 1, which are needled onto raking rakes 2a.
  • the method can also be used for gripping any textile surface.
  • the boards 4 can work in opposite directions to form a gap in several gripping modules.
  • the invention is not limited to the exemplary embodiment shown and described, but rather allows numerous modifications.
  • the functions of separating and slipping on can be carried out with separate elements or the geometric position of the functional elements can be selected differently.
