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, rotationally secured winding body and a material feed channel rotating about the axis of the winding body.
  • filamentary material e.g. Weft yarn, wire, ribbon, etc.
  • the material feed channel consists of a hollow shaft carrying the winding body, which has a bent part, over which the material (hereinafter For example, weft thread of a weaving machine is assumed) is wound onto the winding body. Dirt, in particular fiber fly, can accumulate in the bent parts of the feed channel during operation, which cannot be determined easily. The elimination due to the bends is also not easy. Finally, the hollow shaft with the bent-off channel section also forms a relatively complicated component of the device.
  • the invention has for its object a particular to create improved facility in this regard.
  • the invention consists in that the material feed channel consists of a straight, tubular part which is at an angle to the axis of the winding body and which itself has a material inlet end and a material outlet end.
  • a straight material feed channel makes it easier for the operator to see through and to detect any contamination. For the rest, a straight, non-cranked feed channel is less likely to become dirty than a cranked channel. Threading through a straight feed channel becomes easier. Furthermore, the entire inlet section of the storage device is simplified.
  • the tubular part is mounted such that it can rotate about its own axis in a drive body which is arranged so as to be rotatable about the axis of the winding body. It can thereby be achieved that the feed channel is constantly e.g. due to vibrations more or less rotates around its own axis. As a result, the wear at the inlet end as well as at the outlet end of the channel is distributed over the entire circumference, so that it is no longer noticeable.
  • a drive body 4 is rotatably mounted, which e.g. can be set in rotation on its shoulder 51 by means of a belt drive.
  • the drive body 4 contains, with the interposition of needle bearings 5, a straight tube 6 for feeding the weft thread 7 coming from a supply spool, indicated by dash-dotted lines, onto a winding body designated as a whole by 8.
  • the tube 6 is at an angle A of e.g. 40 ° to the bobbin axis 25.
  • the drive body 4 continues in FIG. 1 on the right in a shaft end 11 on which, with the interposition of ball bearings 13, a winding body designated as a whole as 8 is rotatably mounted, but is secured against rotation by a 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
  • Inside the winding body 8 is a screw 15 and a worm wheel 16 driven star wheel 17.
  • the teeth 18 of the star wheel 17 reach out through an opening 19 of the winding body 8 and protrude there into a fork-shaped guide bracket 22 attached to the housing pot 2 at 21.
  • 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.
  • the thread inlet end 26 of the tube 6 is always at the intersection 30 of the axes 25, 35 of the body 4 and the tube 6, the thread outlet end 27 is above the winding circumference of the winding former 8, 8.
  • 8 thread turns 31 are placed on the winding former 8, which are pushed to the right by the teeth 18 of the star wheel 17 in FIG. 1 and are withdrawn batchwise during the weft insertion at the end 32 of the bobbin 8.
  • the inlet end 26 of the thread feed tube 6 is arranged in a funnel-shaped opening 34 of the drive body 4, whereby it can be achieved that dirt caused by fiber fly is thrown outwards as a result of the centrifugal force.
  • a compensation rod 44 is arranged in the drive body 4 for mass compensation with respect to the inlet pipe 6.
  • the tube Due to the storage of the tube 6 in the bearings 5, the tube can e.g. due to vibration constantly rotate about its own axis 35, which can prevent wear at the ends 26,27.
  • a magnet 37 for example, can be fastened on the circumference of the thread feed tube 6, which magnet is connected to a magnet in the pot 2 attached permanent magnet 38 cooperates. If, as assumed in the drawing, poles of the same name approach each other during the rotation of the tube 6 about the axis 7, the tube 6 is caused to rotate by the magnetic effect. A further rotation occurs when the magnet 37 comes close to a further magnet 39 arranged in a fixed manner in the pot 2. In this way, a constant rotating movement of the tube 6 about the axis 35 is achieved.
  • a rag 43 made of soft material, e.g. Leather attached, which protrudes into the path of the inlet pipe 6.
  • the tube 6 hits against the tab 43 and is thereby set into a slight self-rotation about its axis 35.
  • the tube 6 is only supported with a certain play in the drive body 4, and needle or ball bearings are dispensed with. Also, this can cause a slight egg g enrotation of the tube about the axis 35 during the operation due to vibration can be obtained.
