  • the wind ratio is generally set to a value that is slightly different from an integer so that ribbon winding does not occur (no repeated winding of the yarn on the same path on the package surface).
  • Patent Document 2 discloses a traverse device capable of performing creeping for suppressing the height of the ear of the package.
  • Ear height is because it is generally difficult to rapidly reverse (direction change) the traverse guide, and the amount of yarn wound around the axial end of the package surface is greater than the amount of yarn wound around other parts. It will be many.
  • the ear height may cause deterioration of the package shape and / or non-uniformity of the package density. Creeping refers to temporarily narrowing the width of the reciprocating region of the traverse guide (traverse width) during package formation.

  • the width of the inversion region in the second inversion control is Wt, for example (see FIG. 7A).
  • the controller 13 makes the second inversion time longer than the first inversion time (Trb> Tra), as shown in FIG. 7 (a). From another viewpoint, the control device 13 gently accelerates / decelerates the traverse guide 33 during the second inversion control as compared to during the first inversion control. More specifically, as compared with the maximum value of acceleration within the first inversion time during the first inversion control (Aa), the maximum value of acceleration within the second inversion time during the second inversion control (Ab) Yes) is made smaller (see FIG. 8A). In other words, the time average value of acceleration during the second reversal time during the second reversal control is made smaller than the time average value of acceleration during the first reversal control during the first reversal control.
  • the control device 13 makes the traverse speed at the time other than the reversal control equal in the normal time and the creeping time (see FIG. 7B). Further, in the second reversal control, the control device 13 moves the traverse guide 33 to the second reversal position when half the second reversal time (Trb / 2) has elapsed since the deceleration of the traverse guide 33 was started.

  • the yarn Y is wound into the winding package Pw as shown in FIG. 9 (a). That is, the portion of the yarn Y that is wound around the winding package Pw during creeping (the yarn Y3) is reversed at the point 107 in the traverse direction. The point 107 is at the same position as the point 104 described above in the rotation angle direction. Further, during the second inversion control (that is, when the traverse guide 33 is moving in the inversion region described above), the yarn Y3 is wound around the winding package Pw in an arc (see FIG. 9A). See hatched area 201).

  • the traverse guide 33 is located at the second reversal position when half the second reversal time (Trb / 2) has elapsed since the deceleration of the traverse guide 33 was started. Therefore, the inverted portion of the yarn Y3 has a symmetrical shape with the center axis of the winding package Pw as the center line. That is, the inverted portion of the yarn Y3 is formed cleanly.
  • the controller 13 increases the width of the reversal region in the traverse direction as the creeping amount increases (see FIG. 8B). For example, when the creeping amount is ⁇ W1 larger than ⁇ W, the control device 13 sets the width of the inversion region to Wt1 wider than Wt (see FIGS. 9A and 9B). That is, when the second reversal time becomes long due to the narrowing of the traverse width during creeping, the region in which the traverse guide 33 can move in the traverse direction becomes wide during the second reversal control. Therefore, it is possible to prevent the traverse guide 33 from being continuously located in a narrow area in the traverse direction for a long time. Further, in this case, the arc drawn when the yarn Y3 is wound around the winding package Pw becomes large (see the area 202 in FIG. 9B).
  • the second inversion time is longer than the first inversion time.
  • the traveling speed of the traverse guide 33 can be made equal between the normal time and the creeping at timings other than the reversal. it can. Therefore, the angles of the yarn Y wound on the surface of the winding package Pw can be made uniform. Therefore, it is possible to prevent the surface shape of the winding package Pw from being disturbed.
  • the larger the creeping amount the wider the reversal area. That is, when the second reversal time becomes long due to the narrowing of the traverse width during creeping, the movable area of the traverse guide 33 becomes large during the second reversal control. Therefore, it is possible to prevent the traverse guide 33 from being continuously located in a narrow area in the traverse direction for a long time. Therefore, it is possible to prevent the yarn Y from being intensively wound in a narrow area on the surface of the winding package Pw.
  • the time from the start of deceleration of the traverse guide 33 until the traverse guide 33 reaches the second reversal position and the time from the departure of the traverse guide 33 from the second reversal position to the completion of the re-acceleration. can be equal.
  • the shape of the inverted portion of the yarn Y can be made symmetrical with respect to the center axis of the winding package Pw (that is, the inverted portion can be formed neatly). Therefore, it is possible to prevent the shape of the inverted portion of the surface of the winding package Pw from being disturbed.
  • control device 13 performs control based on information regarding the relationship between the rotation angle of the winding bobbin Bw and the position of the traverse guide 33.
  • a complicated operation of performing creeping while maintaining a constant wind ratio can be facilitated.
  • by rewriting the information it is possible to easily adjust the position and speed of the traverse guide 33 during the second reversal control.
  • the traverse motor 31 is configured to be able to drive forward and reverse. This allows the traverse guide 33 to reciprocate by the forward and reverse driving of the traverse motor 31. Therefore, the reversing position and timing of the traverse guide 33 can be finely controlled by the control unit. Therefore, fine control of creeping can be easily performed.
  • the traverse guide 33 can be easily linearly reciprocated by stretching the portion of the endless belt 32 to which the traverse guide 33 is attached and driving the same reciprocally.
