Definitions

  • the present invention relates to an elastic yarn take-up winder comprised of a traverse device provided with two bobbin holders, a contact roller, and a traverse guide, and a position transfer means for switching the positions of a bobbin holder in a winding position and a bobbin holder in a stand-by position, whereby a bobbin holder with an empty bobbin and a bobbin holder with a fully wound package are exchanged, and a yarn is transferred onto the empty bobbin when a package becomes full, and further relates to the elastic yarn package formed by the elastic yarn take-up winder.
  • a conventional turret-type elastic yarn take-up winder which switches the positions of bobbin holders by rotating a turret to which two bobbin holders are attached such that when a package becomes full, the package is exchanged with the empty bobbin holder, enabling continuous yarn winding, is common in the art.
  • the turret is operated to rotate in the counter-clockwise direction, moving the full bobbin from the winding position to an intermediary position, and the empty bobbin from the stand-by position to the intermediary position, and then stopped.
  • a yarn winding guide which comprises the winding means winds the elastic yarn once around the empty bobbin, a high-speed brake is applied to the full bobbin, the elastic yarn is loosened, and a section of the yarn is adhered onto the surface of the empty bobbin.
  • the yarn tension generated when the yarn section between the empty bobbin and the full bobbin is wound around the empty bobbin causes the yarn to break between the empty and full bobbins.
  • the yarn which follows the yarn that is adhered onto the empty bobbin is wound on top of the new lead-end yarn tip, fixing it in place.
  • the empty bobbin is returned to the winding position, and actual winding is carried out by the traverse device.
  • the tail-end yarn tip is placed on the top yarn layer of the layered package wound by the take-up winder upon completion of winding.
  • placing the tail-end yarn tip on top of the layered yarn is not a problem, but when the package is a wound package of elastic yarn, the adhesiveness of the elastic yarn may make finding and drawing out the tail-end yarn tip problematic at the next stage of processing.
  • the present invention is an elastic yarn take-up winder provided with a yarn transfer means for transferring the yarn from a full bobbin to a empty bobbin, comprising a tail-end yarn guide for placing yarn introduced to the full bobbin at the end section of a bobbin, away from the layered yarn section of the bobbin, and a lead-end yarn guide for placing the yarn introduced to the empty bobbin at a position outside the yarn path along which the yarn is lead to the full bobbin.
  • the present invention is an elastic yarn take-up winder in which the tail-end yarn guide is an independently moveable moving guide which moves along the bobbin in the bobbin's axial direction.
  • the lead-end yarn guide is independently moveable along the bobbin in the bobbin's axial direction.
  • a second invention of the present invention is an elastic yarn package in which the tails-end yarn tip is wound around the end section of a bobbin, away from the layered yarn section of the bobbin.
  • the present invention is an elastic yarn package in which the lead-end yarn tip is wound at the layered yarn section of the bobbin.
  • the present invention is an elastic yarn package in which the lead-end yarn tip is wound at the end section of a bobbin, away from the layered section of the bobbin, and on the opposite end of the bobbin as the end at which the tail-and yarn tip is wound.
  • M is the elastic yarn take-up winder, comprised of a machine frame 7.
  • the machine frame 7 is provided with an elevating box 1 which is enabled to independently rise and fall, a rotatable turret 2 and a fixed frame 8 on the front of which a control panel 9 is arranged.
  • a contact roller 3 and a traverse device 4 are each held in the elevating box 1.
  • the contact roller 3 applies pressure against the yarn layer surface of a bobbin B at a winding position P 1 .
  • the contact roller 3 is rotationally driven by a driving source (not shown in the drawing) such that the bobbin B being wound is rotated in a counter-clockwise direction.
  • a traverse guide 5 is arranged in the traverse device 4, and engages with an elastic yarn Y, traversing the elastic yarn Y by running within a traverse range.
  • a yarn separating guide (not shown in the drawing) for separating the yarn from the traverse guide 5 is arranged in the upstream side of the traverse device 4.
  • the turret 2 is rotatable via a rotational driving device (not shown in the drawing) centered around a rotary shaft 6.
  • Two bobbin holders 11,12 are each held so as to jut out, and are independently rotatable in the turret 2.
  • a plurality of bobbins B are inserted in each of the bobbin holders 11, 12, with one of the bobbin holders 11 arranged at the winding position P 1 and the other 12 at the stand-by position P 2 .
  • Figure 4 in order to simplify the drawing, only one bobbin B is shown.
  • the elastic yarn Y on the bobbin B of the bobbin holder 11 positioned at the winding position P 1 is wound, and when it becomes a full bobbin FB, the turret 2 is rotated.
  • the full bobbin FB is moved from the winding position P 1 to the stand-by position P 2
  • the pre-arranged empty bobbin EB at the stand-by position P 2 is moved from the stand-by position P 2 to the winding position P 1 .
  • the elastic yarn Y is transferred from the full bobbin FB to the empty bobbin EB via a yarn exchange guide means 13, allowing yarn winding to continue uninterruptedly.
  • the yarn exchange guide means 13 is comprised of tail-and yarn guide 14 and the lead-end yarn guide 15.
  • the tails-end yarn guide 14 positions the yarn Y introduced to the full bobbin FB at an end section Ba of the bobbin B, away from the layered yarn section Pa. It may be comprised of a rod-shaped moving guide 16 with comb-like structures, and arranged so as to be independently moveable along the central axis of the bobbin B.
  • the tail-end yarn guide 14 is attached to the turret 2 such that the rod-shaped moving guide 16 extends along the rotational axis of the turret 2, dividing the winding position bobbin holder and the stand-by position bobbin holder.
  • the rod-shaped living guide 16 may move between the stand-by position at the far end Bb of the bobbin B shown by the double dotted chain line in Figure 4, and the near end Ba of the bobbin B indicated by the continuous line.
  • the lead-end yarn guide 15 is comprised of a swinging arm 17 axially supported in the lower portion of the frame 7 and a guide bar 18 attached to the tip of the swinging arm 17.
  • the swinging arm 17 is arranged on the side of the front ends of the bobbin holders 11, 12, and guide bar 18 is cantilevered from the front ends of the bobbin holders 11, 12 towards the base end of the bobbin holders 11, 12.
  • the rotary shaft 19 of the swinging am 17 is arranged such that the elastic yarn Y can be wound around the empty bobbin EB by the guide bar 18 when the empty bobbin EB is at the yarn exchange position, or in other words, when it is at the intermediary position P 4 indicated by the double dotted chain line in Figure 1.
  • the swinging arm 17 is normally set such that the guide bar 18 and other elements do not come into contact with the full bobbin FB when the turret 2 is rotated.
  • the swinging arm 17 of the lead-end yarn guide 15 is arranged such that it can swing roughly 180 degrees around the center of the rotary axis 19 via a driving means such as a rotary actuator or the like (not shown in the drawing).
  • the guide bar 18 of the lead-end yarn guide 15 is attached to the end of swinging am 17, and is provided with a guiding groove 20 shown in Figure 4, into which slides the elastic yarn Y.
  • the guiding groove 20 is provided with two curved portions 21, 21 that taper in towards each other 21, 21. These curved portions 21, 21 help guide the elastic yarn Y along a curved path. By guiding the elastic yarn Y along the curved portions 21, 21, the yarn Y can be reliably guided to the bottom of the guiding groove 20.
  • the lead-end yarn guide 15 may also be arranged so as to be independently moveable along the axial direction of the bobbin B, as indicated by the double dotted chain line in Figure 4.
  • the lead-end yarn guide 15 moves in the axial direction of the bobbin B, the lead-end yarn tip is wound at the end section Bb of the bobbin B, away from the layered yarn section Pa of the bobbin B, and on the opposite end of the bobbin B from the end at which the tail-end yarn section is wound.
  • the lead-end yarn guide 15 is operated.
  • the lead-end yarn guide 15 catches the yarn section Ya of elastic yarn Y between the empty bobbin EB in the intermediary position P 4 and the full bobbin FB in the intermediary position P 3 , and moves it from the path indicated by the double dotted chain line in Figure 2C to the path indicated by the continuous line (changing the yarn path to that indicated by 1 ⁇ in Figure 3), in order to form the bunch winding in the middle section of the empty bobbin EB.
  • the tail-end yarn guide 14 is operated from back to front in a direction perpendicular to the plane of the page, catching the yarn section Ya of the elastic yarn Y, and moving it from the path indicated by the double dotted chain line to the path indicated by the continuous line (changing the yarn path to that indicated by 2 ⁇ in Figure 3).
  • the yarn section Ya is moved from the layered section Pa to the end section Ba of the full bobbin Fb.
  • the tail end yarn tip is wound at the end section B of the full bobbin Fb.
  • the tension of the yarn section Ya is reduced.
  • the yarn section Ya is wound onto the surface of the empty bobbin EB.
  • the yarn tension created when the yarn section Ya between the empty bobbin Eb and the full bobbin Fb causes the yarn to break between the empty bobbin EB and the full bobbin FB, and the yarn which follows the elastic yarn Y from the tail-end tip wound onto the empty bobbin EB is wound on top of the new lead-end yarn tip.
  • the empty bobbin EB is returned to the winding position P 1 , as shown in Figure 2E and Figure 2F, and the actual winding is carried out with the traverse device 4.
  • the lead-end yarn tip Yc is formed as a bunch winding in the middle section in the axial direction of the bobbin B (the middle section in the axial direction of the layered yarn section Pa), and the tail-end yarn tip Yd is moved from the layered yarn section Pa and wound around one end Ba of the bobbin B.
  • the lead-end yarn tip Yc is moved from the layered yarn section Pa and wound at one end Bb of the bobbin B.
  • the tail-end yarn tip Yd is moved from the layered yarn section Pa to the other end Ba of the bobbin B.
  • the tail-end yarn tip Yd is wound onto one end of the bobbin Ba away from the layered yarn section Pa, and therefore the tail-end yarn tip Yd is very easy to find and draw out.
  • the lead-end yarn tip Yc is wound onto a different end Bb of the bobbin B as the tail-end yarn tip Yd, and thus not only is the lead-end yarn tip Yc easy to find and draw out, but the lead-end yarn tip Yc and the tail-end yarn tip Yd do not overlap.
  • the elastic yarn take-up winder which, by winding the tail-end yarn tip with the tail-end yarn guide which moves the yarn being led onto the full bobbin towards an end of the bobbin away from the layered yarn section of the bobbin, produces an elastic yarn package in which the tail-end yarn section can be easily found and drawn out, is provided. Further, the elastic yarn take-up winder for producing the elastic yarn package operates extremely effectively.
