  • a concentric sprocket 50 is mounted and this is linked to a sprocket 53 mounted on the output shaft of a reduction gear 52 of a vertical swing motor 51 via a chain 54.
  • the vertical swing system 5 rotates the operating arm 4 in the vertical direction via the base pipe 44 due to the forward and reverse rotation of the vertical swing motor 51 mounted on the main frame 7.

  • a cam follower 70 that fits with a guide groove 69 of the coupling member 60 is mounted on the other end of the lever member 64.
  • the guide groove 69 is formed along the peripheral surface of that semi-circle so that the coupling of the lever member 64 and coupling member 60 is maintained regardless of whether the operating arm 4 swings upwards or downwards.
  • the rotational driving of the lateral swing motor 61 is converted and transmitted by a two step lever system, and thus lateral movement to the left and right within a predetermined width is carried out.

In short, as shown in Figure 7A, it prevents the suction nozzle 42 of the swinging operating arm 4 from contacting the edge of the feed roller 2 or the like.
  • some point along the suction nozzle 42 is split and joined by a coil spring 83 and is able to bend at his position so that there is no damage to the rotating operating arm 4 if it should strike the cover 80 as a result of a timing error or the like.
  • this coil spring 83 it is preferable for this coil spring 83 to be so arranged that the pair of coil lines are lined up with no gap in between in order for it not to influence the actions of the suction air a. Furthermore, instead of the coil spring 83, linking may be carried out by a synthetic resin having a suitable degree of elasticity and flexibility.
  • the tow T is taken up by being sucked into the suction nozzle 42 of the tip of the operating arm 4 at the supply position of the spinning device side.
  • surplus tow T is stored in the storage space 12 of the waste box 9 after passing through the outer cylinder 40 and inner cylinder 41.
  • the tow T is pulled from the supply side while maintaining a suitable tension.
  • the diameter of this operating arm 4 increases sequentially from the suction nozzle 42 of the tip to the inner cylinder 41, outer cylinder 40 and base pipe 44, the tow T is smoothly sucked in without catching on anything at any point.
  • the travelling car 3 runs as far as the arrangement position of the feed rollers 2 by the driving of the travelling motor 28 and then exchanges the speed to a uniform speed when running along the roller arrangement direction once it has reached the position of the first feed roller 2 to be wound.
  • This start position may be detected by calculation of the travelled distance or may cause the resetting of the home point by the detection of marks (Refer to number 89 in Figure 12) arranged on the floor 31 by the sensor 39.
  • the operating arm 4 is moved in the vertical and lateral directions by the operation of the vertical swing motor 51 and lateral swing motor 61 and the held tow T is sequentially threaded on each feed roller 2.
  • the desired shape is formed.
  • the path 84 may be simply altered corresponding to the arrangement and size of the feed rollers 2 being the object.
  • tow T is threaded in a arc shape when seen from the arrangement direction of the feed roller 2 as shown in Figure 7A but as it is aligned along the same plane in the production line direction while sliding along the roller peripheral surface as tension takes effect when operation resumes, there is no obstruction to the subsequent feed processing.
  • swing movements stop at that place 85.
  • tow threading at that place 85 may be performed. Then, after passing this place 85, vertical and lateral swing movements are resumed.
  • the movement exchange of the operating arm 4 is carried out based on the detection of marks 86 arranged on the floor 31 for example by the sensor 39.
  • the driving and control of the operating arm 4 is simplified and the production costs and running costs can be kept low.
  • the operating arm 4 is made pipe shaped and the tow T is held by suction air a, there is no requirement for a complicated chuck system and threading on a production line (draw off part 1) directly linked to a spinning device may be carried out without the dispersal of continuously produced tow T.
  • Surplus tow T may be stored in the waste box 9. In short, correct tow threading may be carried out without stopping the production operations of the spinning machine.
  • the suction nozzle 42 carries out threading of tow on the feed rollers 2 by following the a roughly arc shaped path but if a guide 87 that guides the tow T is arranged or if a short feed roller 88 is arranged ( Figure 7B), this path 84 may be insufficient.
  • the position and movement path of the suction nozzle 42 may be changed as shown by the double dotted line in the drawing by the suitable projection of the inner cylinder 41 by the operation of the extension-retraction motor 71, and thus tow threading may be performed on guides 87 and differently shaped rollers 88.
  • Figure 10 shows another embodiment of the lateral swing system 91 of the present invention with the operating arm 92 being freely able to slide in the running direction A with respect to the travelling car 3 and the synchronization of the running direction and vertical swing movement being performed by a cam 93 and lever 94.
  • the suction nozzle 42 is able to move along a predetermined path and tow threading on orderly arranged feed rollers 2 may be performed.
  • the automation of fiber bundle threading on processing rollers is realised and achievements such as a decrease in the operation load and increase in the operating efficiency are demonstrated.
  • the travelling car and operating arm may be driven by a simple system and thus contribute to a decrease in the costs.
