Description

  The present invention relates to a yarn winding machine that forms a package by winding a yarn around a bobbin while traversing the yarn.

  Conventionally, a yarn winding machine is known that forms a package by winding it around a bobbin while traversing the yarn with a traverse device, and such a yarn winding machine includes a fully wound package. In order to transfer the yarn to the empty bobbin, a shifter device is provided that removes the traversed yarn from the traverse device and moves it outside the traverse range.

  For example, in Patent Document 1, two bobbin holders each having a plurality of bobbins mounted in series along the axial direction are rotatably supported by a turret, and the bobbin holder is moved to a winding position and a retracted position by the rotation of the turret. The yarn winding machine to be switched at is disclosed. In the yarn winding machine described in Patent Document 1, when switching between the bobbin holder in the winding position and the bobbin holder in the retracted position, the fully wound package mounted on the bobbin holder in the winding position is used. A shifter device is provided to transfer the yarn to an empty bobbin mounted on the bobbin holder in the retracted position.

  The shifter device described in Patent Document 1 is common to all the yarns for extruding a plurality of yarns traversed by the blade guides of the blade-type traverse device and removing them from the corresponding blade guides. And a plurality of movable shifters that push the plurality of yarns removed from the corresponding blade guides outwardly from the traverse range. The plurality of movable shifters are held by a slide member that is common to all the yarns. After the yarn shifted to the outside of the traverse range by the movable shifter is trapped in a slit formed at the end of the bobbin and wound with a rod, it is returned to the traverse range by returning the movable shifter. The bobbin is tail-wound for yarn splicing, and then the traverse to the bobbin is resumed.

Japanese Patent No. 2991004 (FIG. 2)

  By the way, when the number of bobbins attached to one bobbin holder is increased and more yarns are taken up once, the bobbin holder becomes longer in the axial direction, and the plate-like thread is adjusted accordingly. The splash guide will also be lengthened. Then, since the weight of the yarn jumping guide increases, the inertia accompanying the movement increases and the movement becomes slow. Furthermore, the number of movable shifters also increases, and the slide member that holds and moves a large number of movable shifters is also elongated in the same manner as the yarn jump guide. Then, the movement of the movable shifter becomes slow. As described above, when the movement of the yarn jump guide and the slide member becomes slow, it takes a long time to transfer the yarn, and many yarns are wasted. In addition, for example, when the number of bobbins attached to one bobbin holder (the number of yarns to be wound) increases or decreases due to model change or the like, it is difficult to divert the yarn jumping guide or the slide member. It is necessary to make it again.

  Accordingly, an object of the present invention is to provide a yarn winding having a shifter unit that can be quickly detached and thread-shifted by a configuration that can be divided for each unit, and can flexibly cope with an increase or decrease in the number of bobbins. It is to provide a take-up machine.

In the yarn winding machine of the present invention, a plurality of bobbins are mounted in series along the axial direction, and a winding shaft that winds the yarn around each of the plurality of bobbins, and a winding shaft that winds around each of the plurality of bobbins. A plurality of traverse devices traversing the plurality of yarns respectively in the axial direction of the corresponding bobbins, and removing the plurality of yarns from the plurality of traverse devices, respectively, outside the traverse range of the corresponding traverse device A plurality of shifter units for shifting, and the plurality of shifter units are individually attached to the plurality of traverse devices, and are divided for each unit together with the plurality of traverse devices.

  According to the yarn winding machine of the present invention, the plurality of shifter units can be divided into units. As a result, the shifter unit alone can be suppressed to the minimum size that can realize yarn removal and yarn shifting, and can be made compact, and yarn removal and yarn shifting can be performed quickly. In addition, the shifter unit can be easily increased or decreased, and it is possible to flexibly cope with an increase or decrease in the number of bobbins attached to the winding shaft (the number of yarns to be wound).

Further, since the shifter unit has a compact size as described above, it can be provided in the traverse device. And the maintainability can be further improved by removing the shifter unit together with the traverse device.

  At this time, each shifter unit is preferably removable from the corresponding traverse device.

  According to this, the maintainability of the shifter unit can be further improved.

  Each shifter unit includes: a slide member that is slidable along the axial direction of the take-up shaft; and a yarn removal member for removing the yarn from the traverse device in conjunction with the movement of the slide member. The slide member is provided on the slide member, contacts the yarn removed from the traverse device by the yarn removal member, and moves the yarn to the outside of the traverse range in accordance with the movement of the slide member. It is preferable to have a yarn gathering member.

  According to this, the yarn is removed from the traverse device by the yarn removing member by sliding the slide member. Then, the yarn removed from the traverse device by the yarn shifting member can be moved outside the traverse range.

  At this time, it further includes drive means for driving the plurality of shifter units, and the plurality of slide members are connected and arranged side by side along the axial direction of the winding shaft corresponding to the plurality of bobbins. Preferably, the driving means is connected to one slide member among the plurality of slide members and slides the slide member along the axial direction of the winding shaft.

  According to this, since the yarn removing member and the yarn holding member are driven in conjunction with the driving of the slide member by one driving means, the yarn removed from the yarn traversed by the traverse device and the yarn removed from the yarn are driven. It is possible to perform agility by linking the two operations of the yarn shifting out of the traverse range of the strip. At this time, if one slide member is slid by one driving means, the other slide members connected thereto are also slid in the same manner, and the same operation is performed for all shifter units. Can do. Thereby, the number of drive means can be reduced and cost can be reduced.

  Further, the yarn shifting member includes a yarn shifting portion that moves the yarn outward from the traverse range, a yarn returning portion that opposes the yarn shifting portion with a space therebetween, and returns the yarn to the traverse range. It is preferable to have.

  According to this, the yarn can be pushed to the outside of the traverse range by pushing the yarn at the yarn gathering portion, and when the yarn gathered yarn is returned to the traverse range, the yarn returning portion always follows the movement of the yarn returning portion. Thus, the yarn can be returned and the yarn does not sag and the amount of tail winding can be stabilized.

  In addition, the yarn moving member moves from one end of the traverse range to the outside of the one end as the slide member moves, and when removing the yarn from the traverse device, Located at one end, the yarn removing member can swing with respect to the slide member so as to intersect the trajectory of the yarn during traversing in conjunction with the movement of the slide member. And at least one end of the traverse range swings between a retracted position that does not contact the yarn and a yarn removal position that contacts the yarn, When the slide member moves and the yarn removing member is in the yarn removing position, the yarn traversed from the other traverse range to the one side is out of the moving locus and the yarn removing It is preferably held between moves along the timber and the thread pulling part of the yarn handling member and the yarn return unit.

  This makes it possible to reduce the stroke of the yarn holding member when the yarn holding member moves the yarn. Further, the yarn traversed from the other side of the traverse range by the traverse device is moved along the arm-shaped yarn removing member, held by the yarn holding member, and the yarn is removed from the traverse device. . In this way, by removing the yarn using the traverse device, the stroke of the yarn removing member swinging can be reduced when removing the yarn.

  It becomes possible to suppress the shifter unit alone to the minimum size that can realize yarn removal and yarn shifting, and to make the size compact, and it becomes possible to quickly remove yarn and yarn shifting. In addition, the shifter unit can be easily increased or decreased, and it is possible to flexibly cope with an increase or decrease in the number of bobbins attached to the winding shaft (the number of yarns to be wound).

  Next, an embodiment of the present invention will be described. FIG. 1 is a side view of a yarn winding machine according to the present embodiment. FIG. 2 is a front view of the yarn winder. As shown in FIG. 1, the yarn winding machine 1 is continuously supplied with a plurality of yarns Y from a spinning machine (not shown) located above. The yarn winder 1 is configured to wind a plurality of yarns Y supplied from the spinning machine around a plurality of bobbins B to form a plurality of packages 10.

  As shown in FIGS. 1 and 2, the yarn winding machine 1 includes a main body frame 2, an elevating frame 3 provided on the main body frame 2 so as to be movable in the vertical direction, and a rotatable structure on the main body frame 2. The disc-shaped turret 4, the two bobbin holders 5 (winding shafts) to which one end is supported by the turret 4 and a plurality of bobbins B are mounted, and the plurality of bobbins B wound around the plurality of bobbins B A plurality of traverse devices 6 traversing the yarn Y, a contact roller 7 capable of contacting a plurality of bobbins B mounted on the bobbin holder 5, and a yarn Y traversed by the traverse devices 6 are traversed. A plurality of shifter units 8 and the like are provided for bringing them outside the range.

  The turret 4 has a disk shape and is provided on the main body frame 2 so as to be rotatable. One end of the two bobbin holders 5 is supported at two positions symmetrical to each other with respect to the axis 4 a that is the rotation center of the turret 4, and the two bobbin holders 5 project from the turret 4 so as to be rotatable. ing. These two bobbin holders 5 are moved integrally with the rotation of the turret 4. A plurality of bobbins B are mounted on the two bobbin holders 5 in series in the axial direction of the bobbin holder 5.

  The turret 4 is driven to rotate about a shaft 4 a by a rotary motor 31. When the turret 4 is rotated, the two bobbin holders 5 are in contact with the contact roller 7 and are wound below the winding position P1 where the yarn Y is wound around the bobbin B, and the winding position P1. It can move over a winding position P1 and a standby position P2 that is point-symmetric with respect to the shaft 4a of the turret 4. When the yarn Y is wound around the bobbin B attached to the bobbin holder 5 at the winding position P1, and the fully wound package 10 is formed, the bobbin holder 5 positioned at the winding position P1 and the standby position P2 The bobbin holder 5 located at the position can be switched with respect to each other.

  The two bobbin holders 5 supported by the turret 4 are each driven to rotate by a rotation motor 32. When the bobbin holder 5 at the winding position P1 rotates, the plurality of yarns Y are wound around the plurality of bobbins B attached to the bobbin holder 5, respectively.

  The elevating frame 3 is a long frame extending in the axial direction of the bobbin holder 5, and is supported by the main body frame 2 at the base end portion in the longitudinal direction. The elevating frame 3 is connected to a rod of a cylinder (not shown) fixed to the main body frame 2 and drives the cylinder to move up and down with respect to the main body frame 2 (direction in contact with and away from the bobbin holder 5). It is configured to be movable.

  FIG. 3 is a perspective view of the traverse device and the shifter unit. As shown in FIGS. 1 to 3, the traverse device 6 is a so-called blade-type traverse device 6 provided in the lifting frame 3, and includes a fulcrum guide 19, two blade guides 21, a traverse guide 22, and the like. A traverse motor 33 for rotating the two blade guides 21 is provided. The fulcrum guide 19 is provided in the vicinity of the upper end portion of the elevating frame 3 and is used to hang the yarn Y supplied from the spinning machine, and serves as a traverse fulcrum of the yarn Y.

  The two blade guides 21 are accommodated in a traverse cassette 20 (see FIG. 3), are provided downstream of the fulcrum guide 19 in the traveling direction of the yarn Y, and are coaxially opposed to each other by a traverse motor 33. It is a blade-shaped guide that rotates in the direction. Then, after the yarn Y is moved in one axial direction of the bobbin B by one blade guide 21, the yarn Y is delivered to the other blade guide 21 at the end point position (end position of the winding width of the bobbin B). The yarn Y is moved to the other axial direction of the bobbin B by the blade guide 21. By repeating this operation, the yarn Y traveling through the fulcrum guide 19 is guided to the contact roller 7 while traversing in the axial direction (traverse direction) of the bobbin B with the fulcrum guide 19 as a fulcrum.

  The traverse guide 22 is disposed immediately below the traverse cassette 20 and is connected to the traverse cassette 20 by screws 59, and has an arc-shaped side surface. When viewed from the front, the arc-shaped side surface is the traverse cassette. It protrudes forward from 20. The yarn Y that is traversed by the blade guide 21 is slid and traversed while in contact with the side surface of the traverse guide 22.

  The plurality of traverse devices 6 includes a traverse cassette 20 that accommodates two blade guides 21 and a unit comprising a traverse guide 22 connected to the traverse cassette 20 at the end (for winding one yarn Y). Each traverse device 6 can be detached from the elevating frame 3.

  The elevating frame 3 holds the contact roller 7 rotatably via the two support portions 11 and is configured to be movable in the vertical direction with respect to the main body frame 2.

  The contact roller 7 is supported on the two support portions 11 of the elevating frame 3 in a state parallel to the bobbin holder 5. The contact roller 7 can contact a plurality of bobbins B mounted on the bobbin holder 5 at the winding position P1 or an outer peripheral surface of the package 10 formed by winding the yarn Y around the bobbin B. . The contact roller 7 rotates in accordance with the rotation of the bobbin holder 5 while applying a predetermined contact pressure to the package 10 when winding the yarn around the bobbin B, thereby adjusting the shape of the package 10. Further, the elevating frame 3 and the contact roller 7 are moved by a cylinder (not shown) in a direction close to the bobbin B at the winding position P1 (downward) and a direction away from the bobbin B (upward). The relative position to 2 can be changed.

  Next, the shifter unit 8 will be described. FIG. 4 is a plan view of the shifter unit. FIG. 5 is a plan view of the bobbin on which the yarn is wound. In FIG. 4, the traverse cassette 20, the screw 59, and the support member 58 that is a part of the shifter unit 8 are indicated by a two-dot chain line. The shifter unit 8 removes the yarn Y traversed along the traverse guide 22 from the blade guide 21 and moves it to the outside of the traverse range when a bobbin change to be described later.

  As shown in FIGS. 3 and 4, the shifter unit 8 is supported by the support member 58 sandwiched between the traverse cassette 20 and the traverse guide 22 and slidably supported by the support member 58. The slide member 51 is configured to be slidable in the axial direction, a thread removal arm 52 that swings in conjunction with the movement of the slide member 51, and a thread holding member 53 provided on the slide member 51.

  The bobbin change refers to two bobbin holders that are rotated by the turret 4 when the yarn Y is wound around a plurality of bobbins B mounted on the bobbin holder 5 at the winding position P1 to form a fully wound package 10. 5 is switched, and a plurality of empty bobbins B mounted on the bobbin holder 5 newly moved to the winding position P1 are wound on a plurality of packages 10 mounted on the bobbin holder 5 moved to the standby position P2. It is to transfer the yarn Y that is being used. More specifically, the yarn Y wound while being traversed by the package 10 is removed from the blade guide 21 and moved outside the traverse range, and the slit at the end of the bobbin B as shown in FIG. After the yarn Y is drawn into the trap 18 and trapped to form the rod winding 60, the yarn Y is returned to the traverse range, and the spiral tail winding between the slit 18 and the end of the traverse width of the bobbin B is performed. This is the process from winding the yarn Y for piecing, referred to as 61, to restarting the traverse.

  The support member 58 is sandwiched between the traverse cassette 20 and the traverse guide 22 and is fixed between the traverse cassette 20 and the traverse guide 22 by screws 59 that connect the traverse guide 22 to the traverse cassette 20.

  The slide member 51 has an L-shape, and when viewed from the front, the slide member 51 is disposed on the back side of the running yarn Y, and extends in the axial direction of the bobbin holder 5. The support part 55 extended toward the front from the one end part. The main body 54 is slidably supported by the support member 58 and is slidable in the axial direction of the bobbin holder 5 with respect to the support member 58. Further, the main body portion 54 has a notch 54a formed at one end side, and a fitting portion 54b having a shape that can be fitted into the notch 54a at the other end. Further, the main body portion 54 is formed with a triangular recess 54c at the approximate center in the axial direction of the bobbin holder 5 as viewed from the running direction of the yarn Y recessed from the front side surface.

  Similarly to the support member 58, the thread removing arm 52 is detachably fixed between the traverse cassette 20 and the traverse guide 22 by screws (not shown). The yarn removing arm 52 is swingable so that the distal end crosses the traveling path of the yarn Y with the vicinity of the proximal end portion 52a as an axis, that is, protrudes forward from the traverse guide 22, and as it goes toward the distal end portion. Curved to the near side. When the base end portion 52a is urged to the back side by the torsion spring 56 supported by the support member 58, and the slide member 51 is located at the retracted position shown in FIG. The side surface of the corner 52b of the portion 52a is in contact with the side surface of the concave portion 54c of the main body portion 54 of the slide member 51, and is not in contact with the yarn Y traversed by the traverse device 6, that is, more than the traverse guide 22. Located on the far side.

  The thread holding member 53 is connected to the support portion 55 of the slide member 51 so as to be finely adjustable in the axial direction of the bobbin holder 5 and in a direction orthogonal to the axial direction. It has a holding portion 57 that is composed of a yarn gathering portion 57a and a yarn returning portion 57b that are opposed to each other with a gap, and can hold the yarn Y from both sides of the bobbin holder 5 in the axial direction. When the slide member 51 is located at the retracted position shown in FIG. 4, the yarn gathering portion 57 a and the yarn returning portion 57 b are not traversed with the traverse guide 22 when viewed from the traveling direction of the yarn Y, that is, traversed. It is arranged so that it cannot contact the thread Y that is. The opposite corners of the yarn gathering portion 57a and the yarn returning portion 57b that are not facing each other are chamfered so that the yarn Y can easily slide.

  When the slide member 51 is positioned at the retracted position, the yarn Y that is traversed by the blade guide 21 of the traverse device 6 is traversed without contacting the shifter unit 8.

  The slide members 51 of the plurality of shifter units 8 are arranged side by side along the axial direction of the bobbin holder 5, and the notches 54a and the fitting portions 54b adjacent to each other are fitted and connected. A slide member 51 on one end side in the axial direction of the bobbin holder 5 (left side in FIG. 3) is connected to a rod of the cylinder 40 (see FIG. 3) via a bracket (not shown). The slide member 51 is slid in conjunction with the same stroke in the axial direction of the bobbin holder 5. Then, when the plurality of slide members 51 all perform the same operation, the other plurality of thread removal arms 52 and the plurality of thread holding members 53 all perform the same operation. That is, all the shifter units 8 perform the same operation.

  As described above, the plurality of shifter units 8 are configured to be divided for each end, and can be detached from the traverse cassette 20 for each shifter unit 8 by removing the screws 59.

  Here, the traverse device 6 when the yarn Y is wound around the plurality of bobbins B mounted on the bobbin holder 5 at the winding position P1 to form the fully wound package 10 and the above-described bobbin change is performed. The operation of the shifter unit 8 will be described. Here, bobbin change for one bobbin B will be described, and for all other bobbins B, as described above, all the shifter units 8 operate at the same timing. Only explained.

  First, the operation of the traverse device 6 and the shifter unit 8 at the time of yarn removal and yarn shifting of the traversed yarn Y will be described, and then the shifter unit 8 at the time of returning the yarn shifted yarn to the traverse range. Will be described. FIG. 6 is a diagram for explaining yarn removal and yarn shifting of the yarn being traversed. FIG. 7 is a diagram for explaining the return of the yarn that has been gathered to the traverse range. In FIGS. 6 and 7, a diagram of the shifter unit viewed from above is shown above each figure, and a diagram of the shifter unit viewed from the front is shown below.

  As shown in FIG. 6A, while the yarn Y is traversed with the traverse width L and wound around the bobbin B, the slide member 51 is located at the retracted position. Accordingly, the yarn removing arm 52 and the yarn holding member 53 are located at a position where they cannot contact the traversed yarn Y. When the yarn Y is transferred to the empty bobbin B, the yarn Y moves toward one end side in the axial direction of the bobbin holder 5 (one end side in the traverse range) toward the yarn holding member 53 by the blade guide 21. 6 (b), when the cylinder 40 is driven, the slide member 51 is moved from the retracted position to the thread removing position on one end side where the thread holding member 53 in the axial direction of the bobbin holder 5 is provided. Move in the direction of arrow A. Then, the thread removing arm 52 swings and the corner 52b is pushed out from the recess 54c of the main body 54, and stops at a position where it comes into contact with the side surface 54d of the main body 54. The yarn holding member 53 moves to one end of the traverse range. Then, as viewed from the running direction of the yarn Y, the tip side of the yarn removal arm 52 protrudes from the traverse guide 22 and overlaps the yarn holding member 53.

  In this state, the driving of the cylinder 40 is stopped to stop the movement of the slide member 51, the thread removal arm 52, and the thread holding member 53, and then the thread guide 21 causes the thread to move as shown in FIG. When the yarn Y is continuously moved to one end side of the traverse range, the yarn Y moves while contacting the arc-shaped side surface of the yarn removing arm 52 at the tip side from the approximate center of the yarn removing arm 52. After moving along the chamfered side surface of the yarn holding portion 57a of the yarn holding member 53, as shown in FIG. 6D, the yarn holding portion 57a and the yarn returning portion 57b are located at one end of the traverse range. Get in and hold.

  Thereafter, the cylinder 40 is driven to move the slide member 51 from the yarn removing position to the yarn shifting position on one end side. As a result, the yarn Y held by the yarn holding member 53 is fed to the outside of the traverse range while being pushed by the yarn gathering portion 57a. The yarn Y held by the yarn holding member 53 attempts to return to the traverse range from between the yarn shifting portion 57a and the yarn return portion 57b by tension, but contact with the yarn removal arm 52 restricts the return by the tension. Has been. In this way, the yarn Y that is traversed is removed from the blade guide 21 and moved to the outside of the traverse range.

  The yarn Y that has been gathered is wound around the slit 18 of the bobbin B to form a rod winding, and is transferred from the fully wound package 10. Thereafter, when the slide member 51 is returned from the yarn shifting position shown in FIG. 7A to the retracted position, the yarn Y moves together with the yarn holding member 53 in a direction approaching the traverse range. Further, when viewed from the traveling direction of the yarn Y, the yarn removing arm 52 returns to a position on the far side of the traverse guide 22 that does not overlap the yarn holding member 53. Then, as shown in FIG. 7B, the yarn Y held by the yarn holding member 53 and restricted from returning to the traverse range by the yarn removing arm 52 is pushed back by the yarn return portion 57b. The tension is released from between the yarn gathering portion 57a and the yarn returning portion 57b to return to the traverse range. At this time, tail winding is formed between the slit 18 of the bobbin B and one end side of the traverse width. The amount of tail winding is determined by the moving speed of the slide member 51. The yarn Y that has returned to the traverse range is then traversed again by the blade guide 21 of the traverse device 6.

  According to the yarn winding machine 1 of the present embodiment, the plurality of shifter units 8 are configured to be divided into units. As a result, the shifter unit 8 alone can be kept to a minimum size that allows thread removal and yarn shifting, and the size can be reduced to a compact size, enabling yarn removal and yarn shifting with quick and stable operation. . Moreover, it becomes possible to remove or replace each unit, and maintainability can be improved. Further, the shifter unit 8 can be easily increased or decreased. For example, when the number of bobbins B (number of yarns Y to be wound) to be mounted on the bobbin holder 5 is increased or decreased from the conventional machine due to model change or the like. It is possible to flexibly cope with an increase or decrease in the number of B.

  Further, since the shifter unit 8 is configured in a compact size, it can be provided in the traverse device 6 and can be removed together with the traverse device 6. Also, the shifter unit 8 itself can be removed from the traverse device 6. Therefore, the maintainability of the shifter unit 8 is further improved.

  Further, when the slide member 51 is driven by one cylinder 40, the yarn removing arm 52 and the yarn holding member 53 are also driven in conjunction with each other, so that the yarn Y traversed by the blade guide 21 is removed and removed. The two operations of the yarn Y that is out of the traverse range of the yarn Y thus performed can be performed mechanically in an agile manner. At this time, one slide member 51 is slid by one cylinder 40, and the other slide members 51 connected thereto are slid in the same manner, and the same applies to all shifter units 8. The action can be performed. Thereby, the number of cylinders 40 can be reduced and cost can be reduced.

  Further, since the holding portion 57 of the yarn holding member 53 holds the yarn Y from both sides in the traversing direction, the yarn Y is pushed by the yarn shifting portion 57a of the yarn holding member 53 to the outside of the traverse range. Also, when returning the yarn Y that has been gathered to the traverse range, the yarn Y is pushed by the yarn returning portion 57b of the yarn holding member 53, and the movement of the yarn returning portion 57b is followed to always be the same. The yarn Y can be returned at a speed. Therefore, the amount of tail winding can be stabilized without the yarn Y sagging.

  Further, as the slide member 51 moves, the yarn holding member 53 holds the yarn Y at one end portion of the traverse range, and moves to the outside of the one end portion to draw the yarn. Thereby, when the yarn holding member 53 moves the yarn, the stroke of the yarn holding member 53 can be reduced. Furthermore, by using the traverse device 6 to remove the yarn, it is possible to reduce the swinging stroke of the yarn removal arm 52 when removing the yarn. Thus, by reducing the strokes of the yarn holding member 53 and the yarn removal arm 52, the time required for yarn removal and yarn shifting can be shortened, and the bending angle of the yarn Y is also reduced. The slackness of Y can be reduced.

  Also, by removing the torsion spring 56, the thread removal arm 52 that has been urged to the back side can be swung forward greatly, and foreign matter accumulated inside can be removed and the wear state of various members can be confirmed. can do.

  Next, modified embodiments in which various modifications are made to the embodiment will be described. However, the same reference numerals are given to those having the same configuration as in the above embodiment, and the description thereof is omitted as appropriate.

  In the present embodiment, the slide members 51 of the plurality of shifter units 8 are connected and slid in conjunction with one cylinder 40. However, each of the plurality of slide members 51 is provided with a cylinder, You may slide independently.

  Further, in the present embodiment, the shifter unit 8 is detachably provided in the traverse cassette 20, but may be provided in any position such as the lifting frame 3 as long as the position can be removed from the yarn and the yarn can be shifted. .

  Furthermore, in the present embodiment, the thread removal arm 52 and the thread holding member 53 are moved in conjunction with the movement of the slide member 51 by one cylinder 40, but each is provided with driving means such as a cylinder, Each may be moved independently.

  In the present embodiment, the yarn Y is sandwiched between the yarn shifting portion 57a and the yarn return portion 57b. However, when the yarn Y is returned to the traverse range, the yarn return portion 57b that presses the yarn Y is It may not be provided. Even in this case, when the yarn gathering portion 57a moves closer to the traverse range and moves away from the yarn gathering portion 57a, the yarn Y moves so as to approach the traverse range by tension.

  Further, in this embodiment, the yarn removal is performed by using traversing by the traverse device 6, but the yarn removal arm 52 is pushed forward from the moving region of the blade guide 21, and the pushed yarn is removed. The yarn Y may be held by the yarn holding member 53 and moved to the outside of the traverse range.

  In the present embodiment, the present invention is applied to the shifter unit that removes the yarn from the blade-type traverse device and moves the yarn, but any other traverse device configured to reciprocate the guide in the traverse direction may be used. The present invention can also be applied to other traverse devices such as cam drum type, belt type, arm type and the like. The cam drum type traverse device is a device that reciprocates the traverse guide in the traverse direction by rotating the cam shaft by a drive motor along a cam groove formed in a spiral shape on the peripheral surface of the cam shaft. A belt-type traverse device is a device that reciprocates an endless belt, to which a guide is attached, in a traverse direction by a drive motor. The arm-type traverse device is a device that reciprocates an arm member having a guide formed at the tip in a traverse direction by a drive motor.
