Definitions

  • the present invention relates to a take-up winder such as a winder that winds a filament yarn produced by a spinning machine.
  • a body 11 comprises a turret plate 13 from which two bobbin holders 12 protrude and which rotates through 180 degrees to switch the bobbin holders 12 between a winding position and a standby position, and a slide box 15 including a contact roller 14 and provided in the body 11 so as to elevate and lower.
  • the traverse device 16 is composed of a traverse cam 18 with a cam groove 17 formed therein, a traverse shoe 19 engaging with the cam groove 17, and a cover 20 provided in the outer circumference of the traverse cam 18 to regulate the movement of the traverse shoe 19 only in the axial direction. While the filament yarn continuously supplied and wound around the package P is captured by the traverse shoe 19, the traverse cam 18 rotates to traverse the yarn Y over a predetermined width in order to wind it around the package P.
  • Figure 4B shows control of the traverse speed from winding start to winding end.
  • a solid line (a) shows the traverse speed
  • a dotted line (b) shows a ribboning area curve in which ribboning occurs when the number of winding N is 1.
  • a yarn is wound in such a way that during a winding start, the traverse speed is increased, that a specified speed is maintained during winding, and that the traverse speed is gradually reduced so as not to exceed the ribboning area curve (b) until a winding end.
  • a profile of the package P wound by controlling the traverse speed in this manner is as shown in Figure 4A.
  • an outermost layer yarn Ya of the wound-up elastic yarn is likely to drop (end drop) due to handling during a post process or during transportation. If the yarn supply from the package is started in the post process, a defect such as a yarn break any occur due to the end drop.
  • An object of the present invention is to solve this problem in order to provide a take-up winder capable of preventing a yarn from dropping from the end face of a package after wound the yarn around the package.
  • the present invention is a take-up winder for winding a continuously supplied filament yarn around a bobbin inserted into a bobbin holder in order to form a package, while using a traverse device to traverse yarn, characterized in that at the end of package winding, the yarn traverse speed is increased to reduce the traverse width.
  • the aspect of the present invention is a take-up winder, characterized in that at the end of package winding, the yarn traverse speed jumps a ribboning occurrence area.
  • the take-up winder according to the preferred embodiment of the present invention described herein is a take-up winder for elastic yarns that winds elastic yarns.
  • the traverse speed can be varied by using an inverter 31 or the like to drive a drive device 30 for rotationally driving the traverse cam 18 of traverse device 16 in Figure 5A.
  • the drive device 30 is controlled by a traverse speed controller 32 via the inverter 31.
  • the traverse speed controller 32 is input a detecting value of a rotating sensor 35 for detecting the rotation speed (traverse speed) of the traverse cam 18, and comprises a timer 34 for counting the time from the winding start of the package P to its winding end, and a winding end traverse speed increase means 33 for instructing the inverter 31 to increase the traverse speed at the winding end of the package P.
  • the rotation drive means 36 is a rotation drive means for rotating the bobbin holder 12.
  • the rotation drive means 36 is connected to the contact roller 14, and the contact roller 14 is rotated to come into contact with the package P and make it rotate.
  • Figure 2 shows an example in which the traverse speed controller 32 controls the traverse speed.
  • the dotted line is a curve denoting a ribboning occurrence area (ribboning speed) R when the number of winding N is 1, while the solid line is a curve denoting a variation in traverse speed (winding angle pattern) TS.
  • the winding angle pattern TS is located under the curve of the ribboning occurrence area R, and at a winding start To, a traverse speed is gradually increased from an initial traverse speed tso to a specified value tsc. Subsequently, the traverse speed is gradually reduced so as not to intersect the curve of the ribboning occurrence area R, and during a time Tn (several seconds to several minutes) immediately before a winding end Te, the traverse speed is increased from the traverse speed tsn to a value tsm that jumps the ribboning area R. Then, the traverse speed tsm is maintained until the winding end Te.
  • Figure 3 shows a profile of the package P in which the yarn Y has been wound around the bobbin B with the winding angle pattern TS shown in Figure 2.
  • the winding angle is increased to become the winding width Wm smaller than the width W of a normal package.
  • An outermost layer section 110 having a traverse width smaller than the width between the end faces of the package P is formed in an outer circumference 100 of the package P, and a yarn Ye at the winding end is located in the outermost layer section 110. Consequently, even if the yarn Ye drops as shown by the arrow, it remains on the outer circumference 100 of the end face side of the package P and can be prevented from dropping from the end face during a post process.
  • the above embodiment uses the inverter to control the rotation speed of the traverse cam to reduce the traverse width during the winding end, but in the case of a blade traverse device, this device may adjust the traverse width.
