  • the yarn end is sucked into the suction tube.
  • the yarn end is guided back to the drafting arrangement and the yarn is cut in the suction pipe by yarn cutting device.
  • the suction tube is brought back to a resting position.
  • the principle of a ring spinning machine comprising a row of spinning stations, each of which has a drafting arrangement, and the service robot is arranged reversibly displaceably along the row of spinning stations, consists in that the service robot is provided with the yarn end handling device according to the invention.
  • the device moves in simple motions so that it is easily controllable in the space and it is possible to carry out all positioning and motion operations replacing the human hand when guiding the yarn into the working path at the spinning station for the resumption of spinning, whereby these operations include threading the yarn end into a traveler on the ring flange, threading the yarn end into all the elements at the spinning station, while avoiding contact with the other mechanisms of the spinning station, as well as of the service robot and, finally, guiding the yarn end to the drafting arrangement and the resulting resumption of the spinning process.
  • the simple layout ensures a sufficient speed of motion, durability of individual system components, and good operating times.

  • the invention will be described with reference to an exemplary embodiment of a yarn end handling device at a spinning station (also understood as a spinning unit) of a ring spinning machine.
  • the ring spinning machine comprises a row of identical spinning stations arranged next to each other.
  • the spinning station is well-known and therefore the entire spinning station will only be described hereinafter in a simplified manner. Those parts, elements and nodes of the spinning station that are of significance to the present invention will be described in greater detail.
  • the spinning station comprises an unillustrated roving drafting arrangement, below which a yarn twisting and winding device is arranged.
  • the roving is fed from an unillustrated supply package to the drafting arrangement, behind which the yarn being formed passes through a guide eyelet, a balloon limiter and then through a traveler which circulates around the circumference of a flange of a ring 3 which is mounted in a holder on a ring bench 2.
  • the produced yarn is wound on a package 4 on a tube 1, thus forming a bobbin or cop, which is placed on a vertical spindle, which rotates about its vertical longitudinal axis.
  • the yarn package on the tube 1 forms a bobbin, whereby the package 4 on the tube 1 is formed by a continuous reversible vertical linear motion of the ring bench 2 in the interaction with the yarn winding device after the passage of the yarn through the traveler (not shown), which circulates around the bobbin 1 on the flange of the ring 3, whereby due to the traveler being delayed behind the revolutions of the spindle, a twist is created on the yarn, thereby changing the processed roving into the yarn of the desired properties wound on the bobbin.
  • the spindle is usually driven in its lower portion by means of a flat belt driven by a drive shaft.
  • a service robot is displaceably arranged along the row of spinning stations.
  • the service robot comprises mechanisms and means for performing individual service operations at the spinning station or for performing at least some of the service operations at the spinning station, where the service operations serve to put the spinning station into operation to produce yarn.

  • the yarn end 40 handling device then handles the yarn end 40 in the space relative to the individual means of the spinning station, as well as relative to the individual means of the service robot depending on the sequence of the service operations, such as threading the yarn end 40 into the traveler, threading the yarn end 40 into the balloon limiter, threading the yarn end 40 into the guide eyelet of yarn above the bobbin and bringing the yarn end 40 between the end rollers of the roving drafting arrangement such that during the resumption of the spinning process the yarn end 40 is joined to the end of the roving, by which means the yarn production is resumed.
  • the device for the above-described handling the yarn end 40 relative to the spinning station, as well as relative to the means of the service robot is provided with a supporting part 5, which is mounted reversibly vertically linearly displaceably in the direction A+ and A- on the vertical linear guide 6 on the service robot of a ring spinning machine.
