Definitions

  • the invention relates to a device for storing filamentary material, e.g. Weft yarn, wire, ribbon etc., in weaving machines, with an essentially cylindrical winding body and a material feed channel, one of the parts of the winding body / material feed channel being designed to rotate relative to the other part.
  • filamentary material e.g. Weft yarn, wire, ribbon etc.
  • a rotationally secured winding body, a material feed channel rotating relative to this, and thread are assumed as weft material.
  • the object of the invention is to create a storage device which is particularly improved in this regard.
  • the invention resides in at least one hook-shaped recess arranged on the end of the winding body facing the material feed channel for returning a material strand wound incorrectly behind this end of the winding body to the winding body.
  • the back-wound weft strand can be pulled forward again. Storage and web operations can continue undisturbed. The weft yarn does not break off due to such minimal back winding. As a result, the loom is not stopped.
  • the inherent avoidance of back-winding does not have to be paid for by attaching additional parts, such as a protective ring, to the known storage device.
  • the hook-shaped recess can be made on the winding body itself. The mass and the mass inertia of the thread feed channel and the parts rotating with it remain unchanged.
  • the axes 2 and 4 do not coincide with each other, so part 3 is arranged eccentrically on the disc 1.
  • Brackets 5 are arranged in the lower half of the conical part 3 in FIG. 1. Together with the upper section of the conical part 3, they form the actual winding body, designated as a whole by 6.
  • weft thread 9 is wound onto the winding body 6 during operation by a thread feed tube 8 rotating continuously according to arrow 7.
  • the end 30 of the bobbin 6 facing the feed tube 8 is formed by the base plate 1. This is enclosed by a cover-like, conical part, which is only indicated in FIG. 3.
  • the feed pipe 8 runs between the parts 1, 50.
  • tube 8 first reaches position 8a according to FIG. 2, later into position 8b according to FIG. 3, in which a winding body 6 also extends over pins 12 against rotation, stationary bracket 16 is shown.
  • the position 8b according to FIG. 3 is the reversed position of the tube 8, from which the tube 8 is again moved in the forward direction according to arrow 7 after the weft break has been eliminated.
  • the weft thread 9 forms a downward hanging loop 9b (FIG. 3) and when the tube 8 continues to run forward (position 8c, FIG. 4), a thread loop 9c that hangs down particularly far is created.
  • the weft thread strand 10 shown in broken lines in FIG. 5 can reach behind the base plate 1.
  • the weft thread 9 is placed in section 9f in a recess 21 made on the circumference of the base plate 1 and thereby returned to the front of the base plate 1.
  • the recess 21 has a gradually inwardly running inlet flank 22, over which the thread center 10 is gradually lowered as the feed tube 8 rotates according to arrow 7. Following the depression or the deepest point 23 of the recess 21, a steeply outwardly directed flank 24 for catching the thread center 10 is formed.
  • the recess 21 thus has the shape of a hook with a tip 40, the thread first passing through the inlet flank 22 in the direction of rotation 7 and thereupon it is returned from the catching flank 24 to the front of the base plate 1 arranged on the right in FIG. 6.
  • the strand 10 is also pulled. It is therefore possible for the back-wound part of the weft thread, that is to say the weft thread section 10 located behind the base plate 1 in FIGS. 1 to 6, to be pulled out of the storage device automatically. The faulty back winding can thus be eliminated automatically and the operation continues in the normal way.
  • the wound thread strand 10 will only extend over a relatively short arc section of, for example, 120 °. The repair or the automatic return of the thread strand 10 is then further facilitated.
  • a concentric, rotationally secured winding drum 28 is arranged on the axis 2. It has a bulge 29 at its run-up end 30.
  • the recess 21 is made according to FIGS. 1-6.
  • the weft thread 9 is pulled off the drum 28 overhead.
  • the thread feed tube 8 stands still and the drum 28 rotates relative to the tube 8.
  • the catching flank 24a and the slot of the recess 21 are extended in the circumferential direction.
  • the tip 40 is bent somewhat to the left in FIG. 9. This can improve the catch effect.
