Definitions

  • the invention relates to a device for storing thread-like material for weft insertion in weaving machines, with a rotating disk carrying the material and a nozzle directed thereon for supplying air and material.
  • yarn is assumed as the thread-like material.
  • the yarn to be stored is deposited on it in a loop shape by a feed nozzle which is moved back and forth transversely to the direction of rotation of the disk. After being stored, the yarn is drawn off the support disk essentially perpendicular to the surface thereof. The yarn should only be held on the supporting disc by the force of the feed nozzle.
  • the loop-shaped yarn deposit can easily become disordered, so that individual loops can overlap.
  • the withdrawal of the stored yarn can be disturbed because often multiple loops lying one above the other can be removed at the same time instead of one after the other.
  • the embodiment cannot exactly define the beginning and end of the thread length to be stored on the supporting disk; the storage length can therefore only be adapted approximately to the entry length required in the weaving machine.
  • the object of the invention is to create a storage device which is particularly improved in this regard.
  • the device according to the invention lies in at least one single thread clamp which rotates with the disk, can be moved against it and presses the material onto it.
  • a particularly precise point in time for the beginning of a length of storage on the support disk can be defined by the thread clamp. Furthermore, a precise point in time for the end of the storage length and at the same time for the beginning of the weft insertion and thus the withdrawal of the stored thread deposit can also be defined.
  • the device is therefore particularly suitable for air jet looms in which the entry length is to be determined by the length of the storage on the weft storage device.
  • the weaving machine 1 has two cheeks 2, 3, a warp beam 4, shafts 5 and a fabric beam 6.
  • the fabric 7 runs according to arrow 8 from the warp beam 4 through the shafts 5 to the fabric beam 6.
  • the weft yarn 11 is guided by means of a main nozzle 12 arranged on the weft side 71 through the shed formed by the shafts 5 to a suction nozzle 13 arranged on the catch side 72.
  • a frame 15 is attached to the machine cheek 2.
  • a shaft 16 which is vertical in FIG. 2 and is continuously driven by the main drive of the weaving machine 1 during operation, is mounted in it.
  • a support disk 17 for the weft yarn 11 to be stored is fastened on it.
  • the shaft 16 and the disk 17 are driven via a toothed belt wheel 18 and a gear 19.
  • the support disk 17 is recessed in its inner region 21, while it has an elevation 22 (FIG. 2) in an outer region.
  • the disk 17 carries an annular disk-shaped needle felt 23. Its inner area 24 lies in the depression area 21, while the outer area 25 is held in an oblique position relative to the disk 17.
  • a cover plate 26 is arranged.
  • the felt 23 is held down by it and in particular its inner part 21 is pressed down.
  • the outer region 25 is more or less held in the inclined position according to FIG. 2 by the elevation 22.
  • a hub 27 of the thrust washer 26 e.g. three arms 81-83 pivotable about pivot bearings 28, on each of which a clamp 31, 32, 33 provided with compression springs 29 is mounted.
  • Each spring 29 strives to push the associated clamp 31-33 downward in FIG. 2.
  • three tension springs 75 - 77 act on the arms 81-83.
  • the terminals 31 - 33 rotate during operation together with the parts 17, 23, 26 according to arrow 34.
  • a cam disk 37 arranged above it in FIG. 2 and equipped with a cam 36 stands still during operation.
  • Rollers 38 arranged on the arms 81-83 run during operation on the lower surface of the cam disk 37 in FIG.
  • a roller 38 runs over the cam 36, e.g. the arm 82 is pivoted downward in FIG. 2 so that the associated clamp 32 reaches the lower clamp position 32a.
  • this clamp 32 presses on the pane 17 while passing through the associated cutout 84 provided in the felt 23 at the clamps. This allows a piece of thread 51 of the weft thread 11 blown in by a stationary nozzle 41 to be held on the pane 17.
  • the weft yarn 11 is drawn off from a metering drum, not shown.
  • the nozzle 41 is protected by a wedge 42 which is arranged in front of the nozzle 41 in the direction of rotation of the support disk 17 (arrow 34).
  • the outer area 25 of the felt disk 23 is raised shortly before the inflation point 92 by the wedge 42, so that the ge drew piece of thread 51 comes to lie on the support plate 17. After placing the thread on disk 17, the felt area 23 can fold down more or less of its own accord, so that the thread piece 51 can be easily held from above.
  • the mode of action is as follows.
  • the disk 17, the felt 23 and the clamps 31 - 33 continuously rotate according to arrow 34.
  • An air stream continuously blows from nozzle 41, through which weft thread 11 is continuously deposited on disk 17 in the form of a loop-shaped thread deposit 51.
  • Terminal 33 passes through the position shown in Fig. 1. It then runs past the wedge 42 in FIG. 2 and reaches the position 33a. In this, the clamp is pivoted downward as a result of the associated roller 38 running onto the cam 36 in FIG. 2. The end of the stored piece of thread 51 is thereby clamped.
  • terminal 33 While terminal 33 is running from position 33 to position 33a, terminal 32 is running from position 32a to position 32b.
  • the associated roller 38 leaves the cam 36 under the action of the adjacent springs 75, 77.
  • the stored piece of thread 51 of certain length is released.
  • the main nozzle 12 receives pressure, the weft insertion begins.
  • the support disk 17 continues to run, the stored, precisely defined thread length 51 is drawn off.
  • a next thread supply of the same length is deposited between terminals 33 and 31.
  • the outer region 25 of the felt 23 is wedged in the sector 61 between two successive clamps 32, 33 during the storage or entry process 42 and the jet from nozzle 41 more or less held in the upper inclined position (corresponding to Fig. 2 left).
  • a slight braking effect on the weft thread 51 located under the felt area 25 can optionally take place. This allows it to be kept taut during the entry.
  • the cam disk 37 can be pivoted and fixed into a desired position by means of screws 93, 94 and an elongated hole 63.
  • the weft storage device can also be used in a weaving machine type other than an air jet machine.
  • the entire storage device 51 is initially consumed during one and the same weft insertion and, in addition, a short piece of thread is drawn directly from the nozzle 41.
