Definitions

  • the invention relates to a feed device for weft threads, catch threads or the like.
  • a feed device for weft threads, catch threads or the like.
  • textile machines consisting of a spreading disc arranged on a drivable shaft with a first disc fixedly arranged on the shaft and a second disc which can be displaced in the axial direction and which is conical in Radial direction to the shaft and towards the first disc has widening ribs which engage in corresponding recesses in the first disc
  • the spacing of the discs can be determined by an adjusting and locking device arranged on the textile machine in such a way that the effective range for the conical ribs guided thread to be fed to the textile machine is fixed.
  • the associated adjusting and locking device has a sleeve which is rotatably arranged on the shaft and which, in cooperation with other actuators, can be coupled either with a slower or a faster drive than the shaft, to change the distance between the disks. Because of the numerous different actuators, this device is very complicated and therefore very susceptible to failure. A further disadvantage is that when the speed of the shaft carrying the spreading disc changes, the speed of the drive elements for the sleeve must also be changed so that the distance between the discs can be changed.
  • a spreading disc is provided with two discs, each of which has conically widening ribs in the radial direction towards the shaft and towards the adjacent disc, each of which engages in corresponding recesses in the adjacent disc.
  • a roller is arranged on the shaft carrying the spreading disc, over which the thread to be fed to the textile machine is guided.
  • the spreading disc is driven by a drive belt. By changing the distance between the discs of the spreading disc, the speed of the shaft and thus the Henge of the thread fed changes.
  • the thread to be fed is not guided over the spreading disc, but the spreading disc only serves as a gear for driving the shaft.
  • the object of the invention is therefore to develop a device of the type mentioned in such a way that the desired amount of thread can be adjusted in a simple and inexpensive construction without stopping the textile machine.
  • the first disc also has conically widening ribs in the radial direction towards the shaft and towards the second disc, which engage in corresponding recesses in the second disc, which is non-rotatably arranged on the shaft
  • the adjusting and locking device has a two-armed arrangement
  • on the textile machine has pivotally arranged levers, one lever arm of which cooperates with an adjusting screw arranged on the textile machine and the other lever arm of which is rotatably connected to the displaceable disc of the spreading disc.
  • the lever is preferably pivotable about an axis perpendicular to a plane running through the shaft in the axial direction.
  • a prestressed spring which is supported on the disks is advantageously arranged on the shaft between the disks of the expanding disk.
  • the disks preferably have recesses for the compression spring.
  • a bearing is arranged on the shaft between the displaceable disc and the lever arm assigned to the displaceable disc.
  • the bearing is preferably designed as an axial thrust bearing, shoulder bearing or the like.
  • the displaceable disk advantageously has a hub-like attachment with a recess for the bearing.
  • the bearing is connected via a U-shaped bracket to the lever arm assigned to the displaceable disk of the expansion disk.
  • a spreading disc 2 composed of two discs 3 and 4 is arranged on a shaft 1 of a textile machine (not shown).
  • the disks 3 and 4 have ribs 5 widening conically in the radial direction towards the shaft 1 and towards the adjacent disk, the ribs of the one disk engaging in the spaces 6 between the ribs 5 of the other disk.
  • the disc 3 is fixed on the shaft 1, while the disc 4 is arranged on the shaft 1 in the axial direction, but non-rotatably.
  • the disc 4 has on its outer side facing away from the disc 3 a hub-like extension 7 with a recess in which a shoulder bearing 8 is seated.
  • a U-shaped bracket 9 is connected to the shoulder bearing 8 and is connected to a lever arm 10 of a two-armed lever 11.
  • the lever 11 is pivotable about an axis 12 perpendicular to a plane running through the shaft 1 in the axial direction.
  • the other lever arm 13 of the two-armed lever 11 is connected to an adjusting and locking device 14 of the textile machine.
  • the adjusting and locking device 14 has an adjusting screw 16 which can be actuated via a knurled wheel 15.
  • the thread 19 to be fed is placed almost completely around the spreading disc, as can be seen in FIG. 1.
  • the compression spring 18 presses the disks 3 and 4 of the expansion disk 2 apart, so that the lever arm 13 bears firmly against the adjusting screw 16 via the U-shaped bracket 9 and the lever 11.
