Definitions

  • the present invention relates to a thread-end cutting method and a thread-end cutting apparatus during doffing in a spinning machine such as a ring spinner and a ring yarn twister.
  • a thread-end cutting portion is provided at a spindle base portion, and a thread-end winding portion is provided in a lower portion of the thread-end cutting portion.
  • a ring rail is rapidly lowered to conduct oblique winding. Thereafter, yarn is wound around the thread-end winding portion. Then, at a time of pulling out full bobbin yarn, yarn (thread-end) connected from the thread-end winding portion to full bobbin yarn is cut at the thread-end cutting portion.
  • Japanese Patent Application Laid-open No. 48-93735 discloses a cutting apparatus in which a bobbin seat for fitting a lower part of a bobbin therein is provided in a yarn holding device having a cutting blade. This cutting apparatus is designed so as to raise the yarn holding device together with full bobbin yarn (package) during doffing.
  • Japanese Patent Application Laid-open No. 62-141135 discloses an apparatus in which a feather portion having directivity of being inclined in a circumferential direction is provided at a thread-end winding portion (thread-end engaging portion), and feathers having an inclined direction different from that of the feather portion are alternately provided.
  • Japanese Patent Application Laid-open No. 6-158442 discloses an apparatus including an underwinding crown fixed to a spindle, and a slide sleeve provided so as to be slidable vertically with respect to a warp through which a spindle is inserted to be fixed.
  • thread-end is designed to be grasped between the underwinding crown and the slide sleeve.
  • FIGS. 9A and 9B an underwinding crown 53 is fixed immediately below a bobbin fitting portion 52 of a spindle 51.
  • a slide sleeve 55 disposed so as to be slidable vertically with respect to a warp 54 is provided with an inner flange 57a for forming a receiving concave portion 56 at an upper portion.
  • a coil spring 58 is inserted between the inner flange 57a and the upper surface of the warp 54. Due to the coil spring 58, the slide sleeve 55 is biased by pressure toward the underwinding crown 53.
  • An outer flange 57b is formed below the inner flange 57a.
  • An abrasion ring 59 is disposed on the outer flange 57b. Furthermore, on a lower surface of a ring rail 60, a protrusion 60a is formed so as to come into contact with the abrasion ring 59.
  • FIG. 9A shows a state in which the ring rail 60 is disposed at a thread-end winding position. In this state, the ring rail 60 resists the biasing force of the coil spring 58, and holds, via the abrasion ring 59, the slide sleeve 55 at a position where a predetermined thread-end winding range is kept between the upper end of the slide sleeve 55 and the lower surface of the under winding crown 53.
  • bobbin yarn 61 is doffed. During doffing, yarn connected to the bobbin yarn 61 is cut.
  • the ring rail 60 is raised up to a winding start position.
  • the slide sleeve 55 is raised up to a position where the underwinding crown 53 is accommodated in the receiving concave portion 56, as shown in FIG. 9B, by the biasing force of the coil spring 58.
  • the thread-end wound around within the thread-end winding range is held in the receiving concave portion 56.
  • thread-end is wound around a spindle several times during doffing, so that the amount of yarn remaining in the thread-end winding portion after doffing becomes large. In this case, every time doffing is repeated, the amount of remaining yarn is increased. This necessitates that disposal of remaining yarn is conducted often. Furthermore, since the winding length of thread-end is large, it is difficult to remove remaining yarn. In the apparatus disclosed in Japanese Patent Application Laid-open No. 6-158442, the slide sleeve must be raised up by the ring rail 60, which makes the structure of this apparatus very complicated. Furthermore, the remaining yarn is pushed into the receiving concave portion 56 after doffing, which makes it cumbersome to remove the remaining yarn.
  • UK Patent Specification GB 1209810 discloses a method and apparatus for breaking off threads in a textile machine, with a device for breaking off threads which lead from the winding body of a tube placed on the textile spindle to an underwinding point provided below the base of the tube, the breaking off of the thread taking place automatically as a result of the doffing of the tube from the textile spindle.
  • the present invention has been made with the foregoing in mind, and it is a primary object of the present invention to provide a thread-end cutting method in a spinning machine in which the amount of yarn (thread-end) remaining in a spindle base portion can be reduced with a simple structure.
  • a thread-end cutting method for a spinning machine comprising the steps of: providing a thread-end cutting member having a bobbin inserting portion, onto which a bobbin of the spinning machine is attached, and a cutter portion provided on the side lower than the bobbin inserting portion so that the thread-end cutting member is raised and lowered along a blade extending upward from a spindle base portion and yarn connected from a traveler to bobbin yarn is grasped between the thread-end cutting member and the spindle base portion; stopping a ring rail at a portion in the vicinity of an abutting portion between the thread-end cutting member and the spindle base portion during doffing; stopping a spindle under the condition that the yarn is wound around the spindle base portion; pulling up the bobbin yarn by a doffing device in this state; raising the thread-end cutting member together with the bobbin yarn up to the middle of pulling; guiding the
  • the bobbin is attached to the spindle under the condition that its lower portion is fitted in the bobbin inserting portion of the thread-end cutting member.
  • the ring rail is lowered by the same operation as that in the prior art during doffing, and the ring rail stops at a portion in the vicinity of the abutting portion between the thread-end cutting member and the spindle base portion. Then, the spindle stops under the condition that the yarn is wound at a position not higher than the abutting portion between the thread-end cutting member and the spindle base portion.
  • the bobbin yarn is pulled up by the doffing device, and the thread-end cutting member is raised together with the bobbin yarn up to the middle of pulling, whereby yarn connected from the bobbin yarn to the traveler is guided between the thread-end cutting member and the spindle base portion.
  • the yarn is grasped between the thread-end cutting member having come off from the bobbin yarn and the spindle base portion, and the yarn is cut by the cutter portion.
  • the end portion of the yarn connected to the traveler is grasped between the thread-end cutting member and the spindle base portion until the subsequent doffing.
  • the length of yarn required for fixing the yarn connected to the traveler to the spindle for the purpose of conducting the subsequent yarn winding can be shortened without providing a complicated yarn gripping portion.

  • the spindle stops under the condition that about one roll or less of yarn is wound.
  • the length of the yarn grasped between the thread-end cutting member and the spindle base portion during doffing can be further shortened.
  • the yarn is exactly connected to the bobbin yarn and comes off from the spindle.
  • suppressing means for suppressing the thread-end cutting member from being raised to more than a predetermined height together with the bobbin yarn, between the blade and the thread-end cutting member, and that the thread-end cutting member comes off from the bobbin yarn when the bobbin yarn is pulled up exceeding the predetermined height.
  • the suppressing means suppresses the thread-end cutting member from being raised, and the thread-end cutting member exactly comes off from the bobbin yarn and grasps the yarn connected from the bobbin yarn to the traveler.
