Definitions

  • the invention relates to a method for operating a weft store of a weaving machine, with a winding body for winding up a number of thread turns to be stored and with a rotating separating disc engaging between the turns with its teeth for moving the stored turns in the direction of the axis of the winding body. Furthermore, the invention relates to a weft thread store for performing the method.
  • a weft thread store with a relatively large diameter of the winding body and a comparatively large number of turns must be used for one and the same weft insertion, so that a sufficient weft length between two successive teeth of the separating disk can be made available.
  • This is particularly the case with weaving machines with a large weaving width of e.g. 5 m and more the case. Since the turns are relatively close to each other, the previous method also easily leads to the case that the separating teeth do not pierce in the right place and thus too many or too few turns are made available in the following tooth gap. There is then a too large or too small shot length in the following tooth gap, which causes disorders in the tissue.
  • the invention has for its object to provide a particularly improved method in this regard and an associated weft store.
  • the inventive method is that a the weft length (weaving width) corresponding number of weft thread windings stored on the winding former is divided by the teeth of the separating disk and divided into at least two tooth gaps between two teeth, such that thread is removed from at least two tooth gaps during one and the same weft insertion.
  • the associated weft thread store is characterized in that the drive for winding the windings on the winding body and the drive of the separating disk are in such a relationship to one another that the drive for winding the turns on the winding body and the drive of the separating disk are in such a ratio to each other that the separating disc is rotated forward by at least one tooth during one and the same weft insertion, such that the thread length for one and the same weft insertion is taken from at least two tooth gaps in the separating disc.
  • the teeth of the separating disc can work more precisely, so that the correct weft thread length is always entered. Since the turns no longer need to be so close together, it can also be avoided that the teeth of the separating disc split open and wound the wound yarn.
  • a weaving machine designated as a whole by 61, has two side cheeks 92, 93, a goods tree 94 arranged between them, a weft feed eyelet 95 and a main entry nozzle 81 for the weft insertion, which is to be fed with compressed air.
  • a pot-shaped housing part 2 is attached to a support arm 1 arranged on the weaving machine 61.
  • a drive body 4 is rotatably mounted, which e.g. can be set in rotation on its shoulder 51 by means of a toothed belt 10.
  • the drive is derived from the main shaft of the weaving machine 61, not shown.
  • the drive body 4 contains, with the interposition of needle bearings 5, a straight tube 6 for guiding the winding body designated by 8 from a supply spool onto a whole.
  • the drive body 4 continues in FIG. 1 to the right into a stub shaft 11 on which the winding body 8 is rotatably supported with the interposition of a ball bearing 13 is, but is secured against rotation by a guide part 22 described in more detail below.
  • the winding body contains a pot-shaped part 53 fastened on a disk 54.
  • rods 14 arranged distributed around the circumference, inserted at part 53 at 55 and adjustably attached for receiving the lower part of the winding on the winding body 8 .
  • a separating disc 17 which is driven via a worm 15 and a worm wheel 16 and can be rotated about the axis 62.
  • the teeth 18 of the separating disc reach out through an opening 19 of the winding body 8 and protrude into the stationary at 21 Housing pot 2 fastened guide part 22. As a result, the winding body 8 is secured against rotation.
  • drive body 4 and stub shaft 11 rotate according to arrow 23, so that thread feed tube 6 rotates around body 4 and stub shaft 11 about the axis 25 indicated by dashed lines.
  • 8 turns of thread 31 are placed on the winding body 8, which can be pushed through the teeth 18 of the separating disk 17 in FIG. 1 to the right and can be drawn off overhead at the end 32 of the winding body 8 during the weft insertion.
  • a compensation rod 44 is arranged in the drive body 4 for mass compensation with respect to the inlet pipe 6.
  • the position of the separating disk 17 according to FIG. 2 corresponds to the angular position of 90 ° of the main shaft of the weaving machine 61.
  • the winding group 72 consisting of the five turns 76 in FIG. 2 has moved to the right against the withdrawal end 32 of the winding body 8.
  • the following turn group 73 formed from the five turns 77 is located to the left of group 72.
  • Group 72 comes from tooth gap 80 between teeth 18f, 18a, group 73 from tooth gap 78 formed between two teeth 18a, 18b.
  • To the left of tooth 18b is a third one the five turns 79 of the turn group 74. It lies in the tooth gap 81 formed by the teeth 18b, 18c.
  • a weft insertion (Pfei] e98) begins.
  • the main entry nozzle 81 receives compressed air, so that the weft thread 7 is inserted into the shed 83 formed by the warp threads 82.
  • Disk 17 runs in the position shown in FIG. 3 (125 ° angular position of the main shaft).
  • the turns 76 of group 72 have already been withdrawn, the turns group 73 is in the position where group 72 was previously due to the forward movement of tooth 16b.
  • Group 74 is still in the same place as before.
  • the first turn of group 73 is being drawn off.
  • the separating disk 17 reaches the position shown in FIG. 5 (235 ° main shaft angle).
  • the winding group 74 from gap 81 is completely used up, a weft brake 85 (FIG. 5) is released so that the upward movement (arrow 90) under the action of a spring can reach the braking position 85a indicated in FIG. 6.
  • the weft thread 7 is pressed against the guide part 22 and brought to a standstill. The shot entry is over.
  • the separating disk 17 has meanwhile been rotated into the position according to FIG. 6 (280 ° main shaft angle).
  • the tooth 18d has emerged from the winding body 8 and lies: behind the winding group 82. It is located in the tooth gap 99.
  • the group 82 is separated from a subsequent group 96 belonging to gap 101 by the tooth 18d.
  • Group 96 is still incomplete at the position according to FIG. 6 and only contains the four turns 97. Another turn is still missing and is then placed on.
  • a turn group of five turns is inserted into each tooth gap, which is then separated from the next turn group, which also comprises five turns, by the following tooth.
  • FIG. 2 it can be seen that after the tooth 18a has dipped into the interior of the winding body 8, the two groups 72, 73 move towards one another and are ready for the entry.
  • the third group 74 intended for the same entry is only shifted to the right by the tooth 18c in FIG. 2 until it is finally available for unwinding in the position according to FIG. 4.
  • the teeth 18c, 18f each have a hook 86 directed backwards in the direction of rotation, by means of which, in the positions according to FIGS the next Weft insertion begins and, for example, the tooth 18c provided with the hook 86 dips into the winding body 8.
  • the number of revolutions of the winding tube 6 can be, for example, 6000 min, corresponding to a weaving machine speed of, for example, 400 min with a weaving width of 3.60 m and a diameter D of the winding body 8 of approximately 8 cm.
  • the associated speed of the separating disk 17 would then be, for example, 2 00 min -1 .
  • the separating disc has 17 teeth which are driven by a planetary gear and are constantly held in a vertical position in FIGS. 2-6 (DE-OS 27 51 380).
  • the separating disc has 17 teeth which are driven by a planetary gear and are constantly held in a vertical position in FIGS. 2-6 (DE-OS 27 51 380).
  • only two successive turn groups from the two associated successive tooth gaps are used for one and the same weft insertion. This is followed by two further groups of turns which are used for a further weft insertion, etc.
  • the method can also be used ) if multi-color operation is to be carried out with the weaving machine and two or more weft thread stores are presented in parallel to the weaving machine, from which weft threads are alternately drawn and drawn in accordance with the weaving program will be carried.
