Definitions

  • the present invention mainly relates to a yarn winding machine that manufactures a package by winding a plurality of yarns fed from a yarn feed roller, onto a plurality of respective bobbins.
  • Patent Literature 1 is Japanese Patent Application Publication No. 2003-226469 .
  • the yarn winding machine disclosed in Patent Literature 1 includes a traverse device and first and second bobbin holders.
  • the traverse device traverses each of a plurality of yarns supplied from a godet roller (yarn feed roller).
  • a plurality of bobbins are attached to each of the first and second bobbin holders.
  • the yarn winding machine manufactures a package by winding yarns on each of a plurality of bobbins of the first bobbin holder. When the manufacture of the package is complete (a full winding package is ready), the yarn winding machine switches a yarn winding target to the plurality of bobbins of the second bobbin holder.
  • An axial length of the godet roller disclosed in Patent Literature 1 is shorter than an axial length of the bobbin holder. Therefore, a distance between the plurality of yarns fed from the godet roller to the bobbin holder becomes wider toward the downstream. As a result, when the plurality of yarns are disengaged from the traverse device during switching of the bobbin, the distance between the yarns becomes narrower, and the yarns come closer to the center.
  • the yarn winding machine of Patent Literature 1 includes a yarn path changing member. The yarn path changing member restricts the movement of each yarn so that the distance between the yarns does not narrow down when the plurality of yarns are disengaged from the traverse device.
  • the yarn winding machine of Patent Literature 1 suppresses narrowing of the distance between a plurality of yarns when the yarns are disengaged from the traverse device.
  • a situation may occur where the distance between a plurality of yarns increases when the yarns are disengaged from the traverse device.
  • this situation can occur when a plurality of yarns are first threaded onto a plurality of bobbins on the bobbin holder.
  • the plurality of yarns spread over a wider range than a range in which the plurality of bobbins attached to the bobbin holder.
  • the present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a yarn winding machine that can facilitate the operation of threading yarns onto a bobbin holder and that can suppress breakage of yarns due to yarn-falling by suppressing a plurality of yarns from spreading over a range wider than a range in an axial direction of a plurality of bobbins held by the bobbin holder when the yarns are disengaged from a traverse device.
  • a yarn winding machine with the following configuration.
  • the yarn winding machine manufactures a package by winding a plurality of yarns fed from a yarn feed roller, onto a plurality of respective bobbins.
  • the yarn winding machine includes a bobbin holder, a plurality of traverse guides, a yarn disengagement guide, restriction guides, and a movement mechanism.
  • the bobbin holder holds the plurality of bobbins.
  • Each of the plurality of traverse guides contacts a corresponding one of the plurality of yarns and traverses the yarn in an axial direction of a bobbin holder.
  • the yarn disengagement guide holds the yarns in a state where the plurality of yarns are disengaged from the plurality of traverse guides.
  • the restriction guides are respectively arranged so as to correspond to both sides of a range in an axial direction of the plurality of bobbins, and restrict the plurality of yarns when being held by the yarn disengagement guide so that positions of the yarns in the axial direction of the bobbin holder are within the range in the axial direction of the plurality of bobbins held by the bobbin holder.
  • the movement mechanism allows for movement of the restriction guide between a restriction position where the restriction guide acts on the yarns to restrict the yarns and a retracted position where the restriction guide is retracted from the restriction position.
  • the yarn disengagement guide is movable between a holding position where the yarn disengagement guide holds the plurality of yarns and a retracted position where the yarn disengagement guide is retracted from the holding position.
  • Each of the restriction guides includes an attachment part attached to the movement mechanism and an action part that acts on the yarns.
  • the restriction guides restrict the yarns so that yarns are within a range in the axial direction of the plurality of bobbins, and thus, the yarns can be suppressed from spreading when the yarns are disengaged from the traverse device. Therefore, the yarn threading operation of threading the yarns on the bobbin holder can be facilitated.
  • the restriction guide can be moved to the retracted position when restriction of the yarns is not required. Therefore, the handling is easy as compared to a configuration in which attachment and removal is required.
  • the restriction guide can be moved between the restriction position and the retracted position without significantly changing the posture of the restriction guide. As a result, a small movement trajectory of the restriction guide can be achieved, and thus a space for arranging other members can be increased.
  • it is possible to suppress occurrence of yarn-falling because the yarns can be suppressed from spreading when the yarns are disengaged from the traverse device. Thus, it is possible to suppress occurrence of yarn breakage due to yarn-falling.
  • the movement mechanism includes a mechanism for sliding the restriction guide in the axial direction of the bobbin holder, at least within the range in the axial direction of the plurality of bobbins.
  • the restriction guide at the restriction position can be slid to disperse winding positions of the yarns restricted by the restriction guide.

  • the restriction guide can be more easily slid as compared to a case where the restriction guide is operated directly by hand.
  • the restriction guide is suppressed from interfering with the operation of other devices.
  • the yarn winding machine preferably has the following configuration. That is, the movement mechanism includes a support rail that is provided along the axial direction of the bobbin holder and supports the restriction guide so that the restriction guide is retained at the restriction position.
  • the restriction guide is slidable in the axial direction of the bobbin holder along the support rail. Sliding of the restriction guide beyond the position where the support rail is arranged causes switching from the restriction position to the retracted position of the restriction guide.
  • a member for assisting with sliding and a member for retaining the restriction guide at the restriction position can be made common.
  • switching from the restriction position to the retracted position can be easily performed.
  • the yarn winding machine preferably has the following configuration. That is, the movement mechanism includes a support shaft member and a connecting member connecting the support shaft member and the restriction guide.
  • the restriction guide When the restriction guide is at the restriction position, the connecting member extends from the support shaft member toward the yarn path in the direction perpendicular to the axis.
  • the restriction guide When the restriction guide is at the retracted position, the connecting member extends from the support shaft member toward the side opposite the yarn path in the direction perpendicular to the axis.
  • the movement trajectory of the restriction guide can be made smaller as compared to a configuration in which the restriction guide itself is reversed.
  • the yarn winding machine preferably has the following configuration. That is, the yarn winding machine includes a first housing and a second housing.
  • the traverse guide is arranged in the first housing.
  • the second housing is arranged to face the first housing across the yarn path.
  • the yarn disengagement guide is arranged on the first housing.
  • the restriction guides are arranged on the second housing.

  • the yarn separating guide is movable between a yarn separating position where the yarn separating guide separates and holds the plurality of yarns, and a retracted position where the yarn separating guide is retracted from the yarn separating position.
  • each of the plurality of yarns can be guided into the traverse range of the corresponding traverse guide and brought into contact (engagement) with the traverse guide.
  • the yarn threading operation is facilitated.
  • the pitch between the plurality of yarns on the bobbin holder is smaller than the pitch between the plurality of yarns on the yarn feed roller.

  • each of the winding units 10 includes a frame 11, a first housing 20, a second housing 30, and a turret plate 40.
  • the frame 11 is a member that holds each component provided in the winding unit 10.
  • the first housing 20 is attached with a traverse device 21.
  • the traverse device 21 reciprocating in a winding width direction (axial direction of the package 92) with a traverse guide 23 described later being engaged with the yarn 91, each of the yarns 91 fed downstream is traversed.
  • the traverse device 21 includes a traverse cam 22, a traverse guide 23, and a traverse motor 24.
  • FIG. 2 illustrates a block diagram of one of the winding units 10.

  • the bobbin holder motor 43 is controlled by the control device 50.
  • the yarn 91 is wound on the upper one of the two bobbin holders 42. Specifically, the yarn is threaded onto the bobbins 90 of one of the bobbin holders 42, and then the other of the bobbin holders 42 contacts the contact roller 31, and the other bobbin holder 42 is rotated in such a state, resulting in winding of the yarns 91 on the bobbins 90 of the other bobbin holder 42 to manufacture the package 92.
  • a distal end support member 45 ( FIG. 1 ) is provided for supporting an end at a free end side of one of the bobbin holders 42 positioned to contact the contact roller 31.
  • the turret plate 40 rotates to switch the positions of the two bobbin holders 42. Thereafter, while the package 92 in which the full winding is achieved is collected, the yarn 91 is wound on the bobbins 90 attached to one of the bobbin holders 42.

  • the yarn threading operation and dead turns will be explained.
  • the winding width direction, the axial direction of the package 92, and the axial direction of the bobbin holders 42 (the bobbin holder axial direction) are all parallel. In the description below, these directions are collectively referred to simply as the "axial direction”.
  • the direction in which the yarn feed roller 100 is positioned with respect to the yarn winding machine 1 is referred to as the "height direction".
  • the side closer to the yarn feed roller 100 in the height direction is called the upper side, and the opposite side is called the lower side.
  • a direction perpendicular to both the axial direction and the height direction is referred to as a "direction perpendicular to the axis".
  • the yarn 91 is wound in a state in which the yarn 91 is not engaged with the traverse guide 23. Also, the traverse guide 23 is driven at a lower speed than usual. Therefore, even after the yarn 91 is engaged with the traverse guide 23 after the yarn threading, the quality of the yarn 91 cannot be ensured until the traverse guide 23 returns to the normal speed. Therefore, it is necessary to wind the yarn 91 of low quality and discard the wound yarn 91 by performing dead turns.
  • the length of the bobbin holder 42 in the axial direction (the length indicated by symbol L2 in FIG. 3 ) is shorter than the length of the yarn feed roller 100 in the axial direction (the length indicated by L1 in FIG. 3 ). Therefore, the pitch between the yarns on the bobbin holder 42 is smaller than the pitch between the yarns on the yarn feed roller 100. When dead turns are performed under such conditions, the following situation may occur.
  • the yarn winding machine 1 includes restriction guides 60a and movement mechanisms 70a.
  • a range in which the restriction guides 60a restrict the position of the yarn 91 is called a restriction range (a length indicated by L3 in FIG. 3 ).

  • the restriction guides 60a are provided so as to correspond to both sides of the range in the axial direction of the plurality of bobbins 90, respectively (in other words, to correspond to both sides of the bobbin holder 42 in the axial direction, respectively). Both sides mean one side and the other side with respect to the center in the axial direction. More specifically, the restriction guides 60a are provided so as to correspond to both ends of the range in the axial direction of the plurality of bobbins 90, respectively.
  • the "end” as used herein is a term indicating not only an end point of such an end but also an area in the vicinity of such an end.
  • restriction guides 60a restricts one or a plurality of yarns 91 on one side in the axial direction
  • the other of the restriction guides 60a restricts one or a plurality of yarns 91 on the other side in the axial direction.

  • the movement mechanisms 70a are provided on both sides in the axial direction, respectively.
  • the two movement mechanisms 70a have a symmetric shape with respect to a plane which is perpendicular to the axial direction and between the two movement mechanisms 70a. Therefore, the two movement mechanisms 70a will be collectively described below.
  • the movement mechanism 70a includes a slide rail (support shaft member) 71 and a support rail 72.
  • the slide rail 71 is a cylindrical member provided along the axial direction.
  • the slide rail 71 is inserted through the through hole of the attachment part 61.
  • the restriction guide 60a can slide along the slide rail 71.

  • the support rail 72 supports the intermediate part 62 to restricts downward rotation of the restriction guide 60a (in other words, downward movement of the action part 63), as illustrated in an upper diagram in FIG. 5 .
  • the restriction guide 60a can be retained at the restriction position.
  • the restriction position is a position where the restriction guide 60a restricts the yarns 91.
  • the support rail 72 is not formed at or near the ends in the axial direction.
  • the movement mechanism 70a there is a range in which the slide rail 71 is formed and the support rail 72 is not formed.
  • the restriction guide 60a slides beyond the position where the support rail 72 is arranged and reaches a range where the support rail 72 is not formed, the intermediate part 62 is no longer supported by the support rail 72, and thus the restriction guide 60a rotates downward (the action part 63 moves downward).
  • the restriction guide 60a moves to the retracted position.
  • the retracted position is a position where the restriction guide 60a is retracted from the restriction position, and does not restrict the yarn 91 (not interfere with the yarn path).

Specifically, if the restriction guide 60a is retracted by being rotated upward by 180 degrees or more (that is, if the attachment part 61 is positioned closer to the yarn path than the action part 63), the movement trajectory of the restriction guide 60a becomes larger. As a result, it is necessary to provide a large space above the restriction guides 60a.

  • the mechanism for retracting the restriction guide 60a by rotating the restriction guide 60a downward is not essential and can be omitted because the restriction guide 60a can be retracted from the yarn path only by being slid in the axial direction.
  • the restriction guide 60a according to the present embodiment is a member for use during dead turns, the restriction guide 60a can also be used in other situations where yarn-falling can occur (for example, during the operation of threading the yarn 91 onto the bobbin 90).
