Silk thread coiling machine

Technical Field

The present invention relates to a yarn winding machine.

Background

Patent document 1 discloses a yarn winding machine (a yarn winding machine of patent document 1) including a winding section (a winding unit of patent document 1) for winding a plurality of yarns spun from a yarn spinning device. Specifically, the winding unit includes: a bobbin holder to which a plurality of bobbins for winding a plurality of wires are attached along a predetermined arrangement direction; and a plurality of fulcrum guides arranged in an arrangement direction to serve as fulcrums when the plurality of wires are traversed, respectively. Further, the yarn winding device of patent document 1 includes a yarn hooking member for hooking a plurality of yarns to a plurality of fulcrum guides (yarn hooking guides of patent document 1). The wire hanging member is formed with a plurality of grooves arranged at equal intervals in correspondence to the number of the plurality of fulcrum guides.

When the operator hooks the advancing plurality of wires to the fulcrum guides, the operator holds the plurality of wires in the plurality of grooves of the wire-holding member. Thereafter, the wire hanging member is moved in a direction diagonally across the plurality of fulcrum guides aligned in the alignment direction. Thus, the plurality of wires are sequentially hooked to the plurality of fulcrum guides from the wire hooking member.

In the yarn winding machine as described in patent document 1, when a plurality of yarns spun from a spinning device are hooked to a plurality of fulcrum guides, a suction gun (suction holding member) for sucking the plurality of yarns intensively is used. Specifically, the plurality of wires are hooked to the plurality of grooves of the wire hanging member in a state where the plurality of wires are sucked together by the suction gun. Further, the yarn is suspended from the yarn suspending member to the yarn guides with the plurality of fulcrums by moving the yarn suspending member while the plurality of yarns are sucked by the suction gun.

However, when the yarn swing caused by the air flow generated at the suction port of the suction gun for sucking the yarn propagates to the plurality of yarns traveling on the upstream side of the yarn hanging member in the yarn traveling direction, there arises a problem that the adjacent yarns are wound around each other or the positions of the yarns held by the yarn hanging member are not determined. Accordingly, the wire may not be properly delivered from the wire-hanging member to the fulcrum guides.

Disclosure of Invention

The invention aims to properly carry out wire hanging from a wire hanging component to a plurality of supporting point wire guides.

The yarn winding machine of the present invention is characterized by comprising: a bobbin holder to which a plurality of bobbins are attached along a predetermined alignment direction; a plurality of fulcrum guides, which are arranged in the arrangement direction and are provided in correspondence with the plurality of threads wound around the plurality of bobbins, and serve as fulcrums at which the plurality of threads are traversed; and a yarn hanging member movable in a state where the plurality of yarns are held separately from each other, wherein the yarn hanging member is moved relative to the plurality of fulcrum guides in a state where the plurality of yarns sucked and held by the suction holding member are held by the yarn hanging member, thereby hanging the yarns to the plurality of fulcrum guides, and wherein the yarn winding machine further includes a yarn contacting portion arranged at a position where the plurality of yarns traveling between the yarn hanging member and the suction holding member can contact.

According to the present invention, by bringing the plurality of wires attracted by the attraction holding member into contact with the wire contact portion between the attraction holding member and the wire hanging member, it is possible to suppress the wire from swinging and propagating to the wire hanging member due to the air flow generated in the attraction holding member. Therefore, the plurality of wires held by the wire hanging member can be delivered to the respective fulcrum guides with the wire swinging suppressed. Accordingly, the yarn can be appropriately fed from the yarn feeding member to the yarn guide having a plurality of fulcrums.

In the yarn winding machine according to the present invention, it is preferable that the yarn hanging on the plurality of fulcrum guides is performed in order from one side to the other side in the arrangement direction, and the yarn contacting portion is located at the other side than the fulcrum guide located at the other side in the arrangement direction.

If the yarn hanging member passes over the yarn contacting portion in the direction of arrangement while being suspended in the yarn guide toward the plurality of fulcrums, the plurality of yarns may be separated from the yarn contacting portion depending on the positional relationship between the yarn contacting portion and the suction holding member. In order to prevent this, the position of the suction holding member needs to be adjusted, but depending on the configuration of the apparatus, there are cases where the position where the suction holding member can be placed is limited due to the presence of other members or the like. According to the present invention, the thread hanging member does not cross the thread contacting portion in the arrangement direction while hanging the thread to the plurality of fulcrum guides, regardless of the positional relationship between the thread contacting portion and the suction holding member. Therefore, the plurality of wires can be prevented from being separated from the wire contact portion in the middle of the wire being fed to the plurality of fulcrum guides.

In the yarn winding machine according to the present invention, the yarn contacting portion preferably has a shape extending in a predetermined extending direction.

According to the present invention, a plurality of wires are easily brought into contact with the wire contact portion extending in the extending direction.

In the yarn winding machine according to the present invention, the yarn contacting portion is preferably inclined or bent such that one end portion in the extending direction of the yarn contacting portion is lower than the other end portion.

After the completion of the delivery of the plurality of wires from the wire-hanging member to the fulcrum guides, the plurality of wires are separated from the wire contact portion in order to transfer to a step of winding the wires around a bobbin mounted on the bobbin holder. According to the present invention, the plurality of wires can be moved in a direction from the other end portion toward the one end portion of the wire contact portion in the extending direction by the action of gravity so as to slide on the wire contact portion. This reduces the force required to move the plurality of wires, and enables the plurality of wires to be smoothly separated from the wire contact portion.

In the yarn winding machine according to the present invention, the bobbin holder is preferably disposed on the one side of the yarn contacting portion in the extending direction.

According to the present invention, the bobbin holder is disposed on one side of the wire contact portion in the extending direction. Therefore, when the plurality of wires are separated from the wire contact portion at a position closer to the wire contact portion in the extending direction than the wire contact portion while being moved downward along the wire contact portion, the plurality of wires are positioned closer to the bobbin holder than the wire contact portion. Thus, the plurality of wires separated from the wire contact portion can be moved directly to the position where the bobbin holder is located without crossing the wire contact portion in the extending direction. Thus, after the completion of the delivery of the plurality of wires from the wire-hanging member to the respective fulcrum guides, the process can smoothly transition to the process of winding the respective wires around the bobbin mounted on the bobbin holder.

In the yarn winding machine according to the present invention, it is preferable that the plurality of yarns move toward one end of the yarn contacting portion in the extending direction while contacting the yarn contacting portion, and the yarn winding machine further includes a drop preventing portion that prevents the plurality of yarns from dropping from the other end of the yarn contacting portion in the extending direction.

According to the present invention, a plurality of wires contacting the wire contacting portion can be prevented from accidentally coming off from the other end portion of the wire contacting portion.

In the yarn winding machine according to the present invention, it is preferable that the yarn hooking member has a plurality of holding grooves for holding 1 yarn each, and the plurality of holding grooves are arranged in parallel with the extending direction.

According to the present invention, the running surface of the yarn passing through the yarn passage of each yarn is maintained in a state parallel to the extending direction until the plurality of yarns hooked to the plurality of holding grooves of the yarn hooking member reach the yarn contacting portion. In other words, the running surfaces of the plurality of wires running between the plurality of holding grooves and the wire contacting portion are not twisted. Accordingly, the bending angle of the plurality of wires contacting the wire contacting portion becomes uniform among the wires, and the quality of the wires affected by the bending angle can be made uniform among the wires.

In the yarn winding machine according to the present invention, the yarn contacting portion preferably has a shape that allows the plurality of yarns to contact each other while the yarn is being wound from the yarn winding member to the plurality of fulcrum guides.

According to the present invention, a plurality of wires can be brought into continuous contact with the wire contact portion while the wires are being hung from the wire hanging member to the respective fulcrum guides. That is, it is possible to prevent a part or all of the plurality of wires from being separated from the wire contact portion during the wire hanging from the wire hanging member to each fulcrum guide. Accordingly, the plurality of wires held by the wire hanging member are delivered to the fulcrum guide while the wire swinging is reliably suppressed. This makes it possible to more appropriately carry out the yarn threading from the yarn threading member to the yarn threading guides with the plurality of fulcrums.

In the yarn winding machine according to the present invention, the yarn contacting portion is preferably a contact surface with which the plurality of yarns can be in surface contact.

The larger the contact area of the plurality of wires with the wire contact portion, the smaller the load each wire receives from the wire contact portion. According to the present invention, by bringing a plurality of wires into surface contact with the wire contact portion, the contact area between each wire and the wire contact portion increases. Therefore, the load received by the plurality of wires can be reduced as compared with the case where the plurality of wires are brought into contact with the edge-shaped wire contact portion, even if the plurality of wires are brought into point contact with the wire contact portion. This can suppress breakage and deflection of the plurality of wires due to contact between the plurality of wires and the wire contact portion.

In the yarn winding machine according to the present invention, it is preferable that the yarn winding machine further includes a winding guide for guiding the plurality of yarns suspended from the plurality of fulcrum guides to a winding position for winding the plurality of yarns around the plurality of bobbins mounted on the bobbin holder, and the yarn contacting portion is integrally formed with the winding guide.

According to the present invention, after the completion of the delivery of the plurality of wires from the wire hanging member to the respective fulcrum guides, the plurality of wires separated from the wire contacting portion can be directly hooked to the winding guide integrally formed with the wire contacting portion. Therefore, the process can smoothly transition to the process of winding each yarn around the bobbin mounted on the bobbin holder.

In the yarn winding machine according to the present invention, it is preferable that the winding guide is disposed below the yarn contacting portion, and the yarn winding machine further includes a guide portion extending in the vertical direction for guiding the plurality of yarns from the yarn contacting portion to the winding guide.

The guide portion can smoothly guide the plurality of wires separated from the wire contact portion to the winding guide. Therefore, after the completion of the delivery of the plurality of wires from the wire-hanging member to the respective fulcrum guides, the process of winding the respective wires around the bobbin mounted on the bobbin holder can be more smoothly shifted.

In the yarn winding machine according to the present invention, it is preferable that the yarn winding machine further includes a driving mechanism for moving the yarn hooking member between a yarn hooking start position at which yarn hooking to the plurality of fulcrum guides is started and a yarn hooking end position at which yarn hooking to the plurality of fulcrum guides is ended.

In the structure in which the yarn hanging member is moved by the driving mechanism, when yarn swinging of the plurality of yarns held by the yarn hanging member occurs, the position of the yarn hanging member cannot be finely adjusted to correct the position of the yarn delivered to the fulcrum guide. In this configuration, it is more effective to provide the wire contact part of the present invention.

In the yarn winding machine according to the present invention, it is preferable that the operation space for the operator to operate the suction holding member to hang the yarn on the plurality of fulcrum yarn guides is located closer to one side of the yarn contacting portion than the yarn winding portion in the arrangement direction, out of one side or the other side of the bobbin holder in the arrangement direction.

According to the present invention, an operator can perform work in a wide space around which the bobbin holder and the fulcrum guide are not disposed.

In the yarn winding machine according to the present invention, the yarn hooking member is preferably disposed downstream of the plurality of fulcrum guides in a yarn traveling direction in which the plurality of yarns travel.

The plurality of wires attracted by the attraction holding member are gathered to the attraction holding member. That is, the pitch of the plurality of wires held by the wire hanging member becomes narrower toward the suction holding member on the downstream side of the wire hanging member. In this regard, in the present invention, the yarn hanging member is arranged on the downstream side of the fulcrum guide in the yarn traveling direction. Therefore, the plurality of wires having the narrowed pitch on the downstream side of the wire-hanging member can be hooked on the fulcrum guide without being hooked on the fulcrum guide, but the plurality of wires having the uniform pitch can be hooked on the fulcrum guide. In this way, in the configuration of the present invention, the yarn is easily suspended from the fulcrum guide as compared with the case where the yarn suspending member is disposed upstream of the fulcrum guide.

Detailed Description

Next, an embodiment of the present invention will be described. For convenience of explanation, the directions shown in fig. 1 and 2 are referred to as the up-down direction, the left-right direction, and the front-back direction. The vertical direction is the vertical direction in which gravity acts. The left-right direction is a direction orthogonal to the up-down direction. The front-rear direction (alignment direction of the present invention) is a direction orthogonal to both the up-down direction and the left-right direction, and is a direction in which a plurality of bobbins B (described later) are aligned. The yarn Y (described later) is set to travel in the yarn travel direction.

(Spinning tractor 1)

An outline of a spinning machine 1 (yarn winding machine of the present invention) according to the present embodiment will be described with reference to fig. 1. Fig. 1 is a side view of a spinning tractor 1. The front side of the paper surface in fig. 1 is the right side.

The spinning drawing machine 1 is configured to draw a plurality of (for example, 32 in the present embodiment) filaments Y spun from the spinning device 2, wind them on a plurality of bobbins B, and form a plurality of packages P at the same time. The spinning machine 1 of the present embodiment is configured such that, for example, for 32 filaments spun from the spinning device 2, 16 filaments are wound by a pair of winding units 5 (described later). Each yarn Y is a multifilament yarn having a plurality of filaments (not shown). The filaments are, for example, synthetic fibers formed from polyester.

The spinning machine 1 includes, for example, a 1 st godet 3, a2 nd godet 4, a pair of winding units 5, a control device 6, a yarn hooking member 30 (see fig. 4), and a sheet metal member 50 (see fig. 2). The 1 st godet 3 and the 2 nd godet 4 are configured to draw the plurality of filaments Y and convey the filaments to the downstream side in the filament traveling direction. The 1 st godet 3 and the 2 nd godet 4 are supported by a long support body 7 extending obliquely rearward and upward from upper positions of the tip ends of the pair of winding portions 5. Fig. 1 illustrates one of the pair of winding portions 5. In fig. 1, the wire hanging member 30 is not shown.

The 1 st godet 3 is a roller whose rotation axis direction is substantially parallel to the left-right direction. The 1 st godet 3 is attached to the front end portion of the support 7. The 1 st godet 3 is rotationally driven by a motor not shown. The plurality of filaments Y spun from the spinning device 2 are transported to the 2 nd godet 4 while being aligned in the left-right direction and wound around the 1 st godet 3.

The 2 nd godet roller 4 is a roller whose rotation axis direction is substantially parallel to the left-right direction. The 2 nd godet 4 is disposed above and at the rear side of the 1 st godet 3. The 2 nd godet 4 is rotationally driven by a motor not shown. The 2 nd godet 4 is disposed obliquely above and rearward of the 1 st godet 3, and is attached to the support 7. The 2 nd godet 4 is configured to be movable along the extending direction of the support body 7. The 2 nd godet 4 is movable between a front position shown by a two-dot chain line in fig. 1 and a rear position shown by a solid line by a roller moving mechanism 9 having a motor, a plurality of pulleys, and an endless belt, which are not shown, for example. The front position is a position that is located forward and downward from the rear position, and is closer to the 1 st godet 3 than the rear position. The front position is a position at which yarn is hung on the 2 nd godet 4. The rear position is a position at which the winding operation of winding the yarn Y on the bobbin B mounted on the bobbin holder 13 is performed. The rear position is also a position at which the yarn is suspended to the plurality of fulcrum guides 20 described later.

The plurality of yarns Y are fed from the 1 st godet 3 to the 2 nd godet 4, and further fed to any one of the pair of winding units 5. One half of the plurality of wires Y is fed to one winding unit 5, and the other half is fed to the other winding unit 5. The yarn path through which the yarn Y traveling from the 1 st godet 3 to the 2 nd godet 4 passes extends obliquely upward.

In the direction of thread travel, a limiting thread guide 8 is provided between the 1 st godet 3 and the 2 nd godet 4. The limiting thread guide 8 is a thread guide that holds a plurality of threads Y in a left-right direction and defines a space between the plurality of threads Y in the left-right direction as a predetermined space.

The pair of winding units 5 are configured to simultaneously form a plurality of packages P by winding a plurality of wires Y around a plurality of bobbins B. The pair of winding portions 5 are disposed below the 1 st godet 3 and the 2 nd godet 4. The pair of winding portions 5 are arranged symmetrically (plane symmetry) with respect to each other. More specifically, the winding portion 5 disposed on the left side and the winding portion 5 disposed on the right side are disposed on both sides of the 2 nd godet 4 in the left-right direction, and are disposed so as to face each other across the yarn paths of the plurality of yarns Y fed from the 2 nd godet 4. The pair of winding units 5 are each configured to wind up half (for example, 16 wires in the present embodiment) of each of the plurality of wires fed from the 2 nd godet 4.

The control device 6 is, for example, a general computer device, and is configured to control the entire spinning tractor 1. The control device 6 is electrically connected to each part of the spinning machine 1, and controls each part according to a predetermined program. The control device 6 has an input unit, not shown, through which an operator can perform an input operation.

(Constitution of winding portion 5)

The detailed configuration of the winding unit 5 will be described below with reference to fig. 1 to 3. Fig. 2 is a front view of the winding portion 5. The front side of the paper surface in fig. 2 is the front side. Fig. 3 is an explanatory view showing movement of the multiple-fulcrum guide 20 described later. In the following, the detailed configuration of the winding unit 5 disposed on the left side of the pair of winding units 5 will be described. As described above, the winding portions 5 are configured symmetrically. That is, the winding portion 5 disposed on the right side has the same structure as the winding portion 5 disposed on the left side, and therefore, the description thereof is omitted. As shown in fig. 2, the winding unit 5 includes a support frame 11, a turntable 12, and two bobbin holders 13.

The support frame 11 is a member extending in the front-rear direction. The support frame 11 is cantilevered from the body 14 provided in a standing state and projects forward (see fig. 1). The turntable 12 is a disk-shaped member having a rotation axis direction substantially parallel to the front-rear direction. The turntable 12 is rotatably supported by the body 14. The turntable 12 is rotationally driven by a not-shown turntable motor. The two bobbin holders 13 are rotatably supported by the turntable 12, and extend forward from the front surface of the turntable 12. The rotation axis direction of each bobbin holder 13 is substantially parallel to the front-rear direction. The two bobbin holders 13 are arranged in a point-symmetrical manner with respect to the center point of the turntable 12 as a symmetry point when viewed in the front-rear direction (see fig. 1). A plurality of bobbins B corresponding to the plurality of threads Y are mounted in a line in the front-rear direction on each bobbin holder 13. The plurality of bobbins B are rotatably supported by the bobbin holder 13. The two bobbin holders 13 are individually driven to rotate by winding motors, not shown.

The winding unit 5 further includes a plurality of yarn guide units 15, a plurality of traverse yarn guides 16, and a contact roller 17. More specifically, a guide support 18 (see fig. 1) extending in the front-rear direction is provided on the upper side of the support frame 11. The plurality of guide units 15 are mounted on the guide support 18 and are configured to be movable in the front-rear direction. The plurality of yarn guide units 15 are provided in correspondence with the plurality of bobbins B, respectively, and are arranged in the front-rear direction. The plurality of wire guide units 15 each have a main body 19 and a fulcrum wire guide 20. The main body 19 is movably attached to the guide support 18. The fulcrum guide 20 is fixed to the main body 19, and serves as a fulcrum for the yarn Y when traversing by each traversing guide 16.

The plurality of yarn guide units 15 (i.e., the plurality of fulcrum yarn guides 20) are configured to be movable between a separation position (see fig. 1) at which the yarn Y is wound around the bobbin B and an approaching position (see fig. 3) at which the yarn Y approaches each other in the front-rear direction compared to the separation position. More specifically, for example, the guide units 15 adjacent to each other in the front-rear direction are connected to each other by a belt not shown. The rearmost wire guide unit 15 can be moved in the front-rear direction by a linear slider, which is not shown, for example. By operating the linear slider, the plurality of yarn guide units 15 can move between a separated position separated from each other and an approaching position closer to the front side than the separated position. As will be described later, when the plurality of fulcrum guides 20 are positioned at the approaching position, threading to the plurality of fulcrum guides 20 is performed.

The plurality of traverse guides 16 are arranged in the front-rear direction. Each of the plurality of traverse guides 16 is driven by, for example, a traverse motor, not shown, and traverses the corresponding yarn Y in the front-rear direction. The contact roller 17 is a roller whose rotation axis direction is substantially parallel to the front-rear direction, and is disposed immediately above the upper bobbin holder 13. The contact roller 17 contacts the surfaces of the plurality of packages P supported by the upper bobbin holder 13, and thereby applies a contact pressure to the surfaces of the packages P to adjust the shape of the packages P.

In the winding portion 5 having the above-described configuration, when the upper bobbin holder 13 is rotationally driven, the yarn Y traversed by the traverse guide 16 is wound around the bobbin B to form the package P. When the package P is full, the upper and lower positions of the two bobbin holders 13 are exchanged by rotating the turntable 12. Thereby, the bobbin holder 13 positioned at the lower side moves to the upper side, and the yarn Y can be wound on the bobbin B attached to the bobbin holder 13 to form the package P again. The bobbin holder 13 to which the package P is mounted is moved to the lower side. The package P that becomes a full package is collected by a package collection device, not shown, for example.

(Filament hanging part 30)

Next, the thread hanging member 30 will be described with reference to fig. 2, 4, and 5. The yarn hooking member 30 is for hooking the plurality of yarns Y to the plurality of fulcrum guides 20. As shown in fig. 2, the yarn hanging member 30 is disposed downstream of the plurality of fulcrum guides 20 in the yarn traveling direction. The yarn hooking members 30 are provided in correspondence with the winding sections 5. That is, in the present embodiment, a pair of wire members 30 are provided. The pair of filament hanging members 30 are formed substantially bilaterally symmetrically with each other, and the same constitution. The yarn hanging members 30 provided in correspondence with the winding sections 5 arranged on the left side of the pair of winding sections 5 will be described below, and the description of the yarn hanging members 30 provided in correspondence with the winding sections 5 arranged on the right side will be omitted.

The wire hanging member 30 is a substantially comb-shaped flat plate member. As shown in fig. 4, the yarn hanging member 30 is formed with a plurality of holding grooves 31 for holding 1 yarn Y. The plurality of holding grooves 31 are arranged in at least the left-right direction. The plurality of holding grooves 31 are arranged in parallel to the extending direction of the wire contact portion 51 described later. The entrance of each holding groove 31 is formed at the rear portion of the hanger 30. The pitch of the plurality of holding grooves 31 is substantially equal to the pitch of the plurality of wires Y in the left-right direction defined by the restriction guide 8. The pitch of the plurality of holding grooves 31 is the distance between the centers of the adjacent holding grooves 31. The yarn hooking member 30 hooks the plurality of yarns Y in the plurality of holding grooves 31 to hold the plurality of yarns Y apart from each other. In the filament hanging member 30 of the present embodiment, as shown in fig. 4, the pitch of the inlets of the plurality of holding grooves 31 is substantially the same as the pitch of the bottom portions of the grooves. However, as shown in fig. 14, for example, the wire hanging member 30 may be configured such that the bottom portion of the groove is wider than the inlet of the plurality of holding grooves 31. Specifically, by making the depth directions of the grooves from the inlets of the holding grooves 31 toward the bottom portion different from each other among the holding grooves 31, the pitch of the bottom portion can be made wider than the pitch of the inlets of the plurality of holding grooves 31. Accordingly, the distance between the wires hooked on the wire hooking member 30 becomes wider, and the wire hooking from the wire hooking member 30 to the plurality of fulcrum guides 20 becomes easier. In this case, the pitch of the inlets of the plurality of holding grooves 31 is substantially equal to the pitch of the plurality of wires Y in the left-right direction defined by the restriction guide 8.

The yarn hooking member 30 is attached to the winding section 5 via a driving mechanism 40. More specifically, a support member 35 (see fig. 3 and 5) whose position is fixed is provided between the support frame 11 of the winding unit 5 and the guide support 18 in the up-down direction. The support member 35 is, for example, a member extending in the front-rear direction. The driving mechanism 40 is attached to the support member 35 of the winding portion 5. Further, the wire hanging member 30 is attached to the driving mechanism 40 via a substantially L-shaped sandwiching member (see fig. 5). That is, the yarn hanging member 30 is attached to the supporting member 35 of the winding section 5 via the driving mechanism 40.

(Drive mechanism 40)

The spinning tractor 1 of the present embodiment further includes a driving mechanism 40, and the driving mechanism 40 is configured to move and drive the yarn hooking member 30. The driving mechanism 40 is provided corresponding to each winding portion 5. That is, in the present embodiment, a pair of driving mechanisms 40 is provided. The pair of driving mechanisms 40 are formed substantially bilaterally symmetrically with each other, and the same configuration is adopted. Hereinafter, the driving mechanism 40 provided in correspondence with the winding unit 5 disposed on the left side of the pair of winding units 5 will be described, and the description of the driving mechanism 40 provided in correspondence with the winding unit 5 disposed on the right side will be omitted.

The driving mechanism 40 moves the yarn hanging member 30 between a yarn hanging start position at which yarn hanging to the plurality of fulcrum guides 20 is started and a yarn hanging end position at which yarn hanging to the plurality of fulcrum guides 20 is ended. The yarn hanging start position is a position near the rearmost fulcrum yarn guide 20 out of the plurality of fulcrum yarn guides 20 at the approaching position (see the two-dot chain line of fig. 5). The yarn hanging end position is a position on the front side of the foremost fulcrum guide 20 among the plurality of fulcrum guides 20 (see the solid line of fig. 5). In the right-and-left direction, the yarn-hanging start position is located on the right side of the yarn-hanging end position. The wire hanging member 30 at the wire hanging start position is moved to the wire hanging end position by moving toward the left obliquely front.

The driving mechanism 40 is attached to the support member 35 of the winding portion 5. As shown in fig. 5, the driving mechanism 40 includes a support arm 61, a guide rail 62, a swing arm 63, a linear slider 64, and a cylinder (not shown). In summary, the support arm 61 to which the wire hanging member 30 is attached via the sandwiching member 42 is moved at least in the front-rear direction along the guide rail 62 by the operation of the linear slider 64. The guide rail 62 swings integrally with the swing arm 63 by the operation of a cylinder (not shown), whereby the direction in which the support arm 61 and the wire member 30 move can be switched.

The support arm 61 is an elongated member extending at least in the front-rear direction. The wire hanging member 30 is fixed to the distal end portion of the support arm 61 via the sandwiching member 42. The guide rail 62 is a substantially linear rail extending at least in the front-rear direction. The guide rail 62 is configured to guide the support arm 61 at least in the front-rear direction.

The swing arm 63 is, for example, a plate-like arm extending at least in the front-rear direction. For example, as shown in fig. 5, the swing arm 63 is disposed at a front side portion of the driving mechanism 40. The rear end portion of the swing arm 63 is connected to the support member 35 via a swing shaft 75 that is in the vertical direction. Thereby, the swing arm 63 can swing integrally with the guide rail 62. The swing arm 63 swings about the swing shaft 75, thereby changing the direction in which the guide rail 62 extends. Thereby, the direction in which the support arm 61 and the wire member 30 move is switched.

The linear slider 64 is a means for moving the support arm 61 in the front-rear direction. The linear slider 64 is a known rodless cylinder operated by compressed air, for example. The linear slider 64 has a cylinder body 81 and a slider 82. The cylinder body 81 extends in the front-rear direction. The cylinder body 81 is fixed to a rear portion of the support member 35 by a fixing member, not shown, for example. That is, the cylinder body 81 is provided integrally with the support member 35. Alternatively, the cylinder body 81 may be welded to the support member 35, for example. The slider 82 is configured to be slidable in the front-rear direction along the cylinder body 81. The support arm 61 is swingably attached to the slider 82. By supplying compressed air to the cylinder body 81 and discharging compressed air from the cylinder body 81, the slider 82 can move between the vicinity of the front end portion and the vicinity of the rear end portion of the cylinder body 81.

The cylinder, not shown, is a device for swinging the swing arm 63 and the guide rail 62. Instead of the air cylinder, another cylinder mechanism driven by a fluid or an electric driving mechanism (for example, a ball screw mechanism, a rack and pinion mechanism, or the like) may be provided.

The driving mechanism 40 described above causes the yarn hanging member 30 in a state where the plurality of yarns Y are held apart from each other to move, thereby hanging the yarns from the yarn hanging member 30 to the plurality of fulcrum guides 20. In the present embodiment, the yarn hanging members 30 are arranged in the order of the rear side to the front side in the front-rear direction on the yarn hanging members 20. The rear side in the front-rear direction corresponds to one side in the arrangement direction of the present invention. The front side in the front-rear direction corresponds to the other side in the arrangement direction of the present invention.

In general, when a plurality of filaments Y spun from the spinning device 2 are hooked to the plurality of fulcrum guides 20, a suction gun 80 (suction holding member of the present invention, see fig. 7) for sucking the plurality of filaments Y intensively is used. Specifically, the plurality of wires Y are hooked to the plurality of holding grooves 31 of the wire hanging member 30 in a state where the plurality of wires Y are sucked together by the suction gun 80. Further, while the plurality of wires Y are sucked by the suction gun 80, the wire hanging member 30 is moved by the driving mechanism 40, whereby the wires are hung from the wire hanging member 30 to the plurality of fulcrum guides. However, when the yarn swing caused by the air flow generated at the suction port 80a of the suction gun 80 for sucking the yarn Y propagates to the plurality of yarns Y traveling on the upstream side of the yarn hanging member 30 in the yarn traveling direction, there occurs a problem that the approaching yarns Y are entangled with each other or the positions of the yarns Y held by the yarn hanging member 30 are not determined. Accordingly, the wire Y may not be properly delivered from the wire-hanging member 30 to each fulcrum guide 20. Accordingly, in order to properly carry out yarn threading from the yarn threading member 30 to the plurality of fulcrum guides 20, the spinning tractor 1 of the present embodiment is configured to include the yarn contacting portion 51.

(Sheet Metal part 50)

Hereinafter, a sheet metal member 50 including a wire contact portion 51 will be described with reference to fig. 2, 6 and 7. The sheet metal member 50 is provided in correspondence with each winding portion 5. That is, in the present embodiment, a pair of sheet metal members 50 are provided. The pair of metal plate members 50 are formed substantially bilaterally symmetrically with each other, and the same structure is obtained. Hereinafter, the explanation of the sheet metal member 50 provided in correspondence with the winding portion 5 disposed on the left side of the pair of winding portions 5 will be omitted, and the explanation of the sheet metal member 50 provided in correspondence with the winding portion 5 disposed on the right side will be omitted.

As shown in fig. 2, the sheet metal member 50 is disposed at the right side portion of the winding portion 5. The sheet metal member 50 is provided on the ground via the leg members 60. The leg member 60 extends to the vicinity of the upper end of the sheet metal member 50 on the rear side of the sheet metal member 50 (see fig. 6). The metal plate member 50 is a metal plate member extending in the left-right direction and the up-down direction. The metal plate member 50 has a substantially trapezoidal shape when viewed from the front-rear direction. The upper left corner and the lower left corner of the sheet metal member 50 are rounded when viewed from the front-rear direction.

As shown in fig. 2, the upper surface of the sheet metal member 50 is located below the fulcrum guide 20 in the up-down direction. The upper surface of the sheet metal member 50 may be positioned above the fulcrum guide 20.

As shown in fig. 6, a wire contact portion 51 that can contact the plurality of wires Y is formed on the upper surface of the metal plate member 50. The upper surface of the metal plate member 50 is inclined such that the left end is lower than the right end. In other words, the extending direction in which the wire contact portion 51 extends is a direction extending obliquely from the lower left toward the upper right. In other words, the wire contact portion 51 is inclined such that the left (one side) end portion in the extending direction is lower than the right (other side) end portion. In the present embodiment, the left-right direction is parallel to the extending direction when viewed from the up-down direction. The extending direction is inclined with respect to the left-right direction when viewed from the front-rear direction. The slope of the extending direction with respect to the left-right direction when viewed from the front-rear direction is, for example, 10 degrees, but is not limited thereto.

As shown in fig. 7, the metal plate member 50 is disposed at a position where the wire contact portion 51 can contact the plurality of wires Y traveling between the wire hanging member 30 and the suction gun 80. More specifically, the sheet metal member 50 is disposed further toward the front side than the forefront fulcrum guide 20 in the front-rear direction. That is, the wire contact portion 51 is located further toward the front side than the forefront fulcrum guide 20 located at the front-rear direction.

The thread contacting portion 51 has a shape that allows the plurality of threads Y to contact each other while the threads are being suspended from the thread suspending member 30 to the plurality of fulcrum guides 20. When specifically described, the following applies. As the yarn is fed from the yarn feeding member 30 to the plurality of fulcrum guides 20, the plurality of yarns Y in contact with the yarn contacting portion 51 move obliquely leftward and downward toward the left end of the yarn contacting portion 51. The length of the wire contact portion 51 in the extending direction is a length sufficient to prevent the plurality of wires Y moving along with the wire hanging from falling off from the left end portion of the wire contact portion 51 during the wire hanging from the wire hanging member 30 to the plurality of fulcrum guides 20.

As shown in fig. 2, the metal plate member 50 is located on the right side of the bobbin holder 13 in the left-right direction. In other words, the bobbin holder 13 is located on the left side (one side) of the wire contact portion 51 in the left-right direction (or extending direction). More specifically, the bobbin holder 13 at the winding position for winding the yarn Y on the bobbin B to form the package P is located on the left side (one side) of the yarn contacting portion 51 in the left-right direction (or extending direction).

The yarn contacting portion 51 is preferably a contact surface with which the plurality of yarns Y can be in surface contact. For example, the wire contact portion 51 has a contact surface rounded when viewed from the left-right direction.

As shown in fig. 6, a drop-off prevention portion 52 is formed on the upper surface of the metal plate member 50, and the drop-off prevention portion 52 prevents the plurality of wires Y from dropping off from the right (other side) end portion of the wire contact portion 51 in the left-right direction (or extending direction). The drop-off prevention portion 52 is a protruding portion formed at the right end portion of the upper surface of the sheet metal member 50. The upper end of the drop-off preventing portion 52 is located above the right end of the wire contacting portion 51.

As shown in fig. 6, a lambda guide 53 (a winding guide of the present invention) having a shape similar to greek letter Λ (lambda) is attached to the leg member 60 (see fig. 6). The lambda wire guide 53 is a wire guide for guiding the plurality of wires Y hooked to the plurality of fulcrum wire guides 20 by the wire hooking member 30 to a winding position for winding the plurality of wires Y onto the plurality of bobbins B mounted on the bobbin holder 13 at the winding position. The lambda guide 53 is disposed below the wire contact portion 51. The lambda wire guide 53 is movable between a standby position (see fig. 6) and a swing position (see fig. 11). More specifically, the lambda guide 53 is movable from the standby position to the swing position by being driven by a cylinder (not shown) and swinging to the left about a rotation shaft 53a extending in the front-rear direction (see solid arrows in fig. 6), for example. The plurality of wires Y are caught by a1 st yarn separator 91 described later as they are caught by the lambda yarn guide 53. The plurality of wires Y hooked to the 1 st wire separator 91 are further caught by a2 nd wire separator 92 (described later), and then guided to respective winding positions determined for the respective plurality of bobbins B. The operation sequence of guiding the lambd guide 53 to each winding position via the 1 st wire divider 91 and the 2 nd wire divider 92 will be described in detail later.

In the present embodiment, the wire contact portion 51 and the drop-off preventing portion 52 are formed on the metal plate member 50. Further, the lambda wire guide 53 is mounted to the leg member 60. The sheet metal member 50 is connected to the leg member 60. That is, the wire contact portion 51, the fall-off prevention portion 52, and the lambda guide 53 are integrally formed.

As shown in fig. 6, a guide 54 is formed on the left side surface of the sheet metal member 50. The guide portion 54 guides the plurality of wires Y from the wire contact portion 51 to the lambda wire guide 53. The guide 54 extends in the up-down direction. In the present embodiment, the guide portion 54 is a side surface of the sheet metal member 50 from the left end portion of the wire contact portion 51 to the lambda wire guide 53.

As shown in fig. 9, the spinning tractor 1 of the present embodiment includes a1 st yarn separator 91 and a 2 nd yarn separator 92. The 1 st wire separator 91 and the 2 nd wire separator 92 provided corresponding to the winding unit 5 disposed on the left side of the pair of winding units 5 will be described below, and the description of the 1 st wire separator 91 and the 2 nd wire separator 92 disposed on the right side will be omitted. Note that, in fig. 1 and 2, description of the 1 st wire separator 91 and the 2 nd wire separator 92 is omitted. In fig. 9, description of each part such as the turntable 12 is omitted as appropriate for the sake of explanation.

The 1 st thread splitter 91 is for temporarily holding the plurality of threads Y hooked to the lambda thread guide 53, and thereafter, the plurality of threads Y are handed over to the 2 nd thread splitter 92. The 1 st thread splitter 91 is attached to the leg 60, for example. The 1 st wire separator 91 may be attached to a member other than the leg member 60. As shown in fig. 9, the 1 st thread-cutting device 91 includes a plurality of 1 st thread-cutting device thread guides 91a and a rotation shaft 91b.

The 1 st thread-dividing thread guides 91a are arranged in the front-rear direction (see fig. 10). The plurality of 1 st thread-dividing guide thread guides 91a are configured to be movable between a separation position at the time of winding the thread Y around the bobbin B and an approaching position (see fig. 10) at which they approach each other in the front-rear direction compared to the separation position. The plurality of 1 st thread-dividing thread guides 91a are movable between the separation position and the approach position by, for example, a linear slider not shown. The pitch of the adjacent 1 st wire separator guides 91a in the front-rear direction when the 1 st wire separator guides 91a are in the separated position is substantially the same as the pitch of the adjacent fulcrum guides 20 of the plurality of fulcrum guides 20 in the separated position in the front-rear direction. Further, the pitch of the adjacent 1 st thread-cutting guides 91a in the front-rear direction means the distance between the contact points of the adjacent 1 st thread-cutting guides 91a in the front-rear direction when the contact point is the contact point of the 1 st thread-cutting guide 91a with the thread Y. Further, the distance between adjacent fulcrum guides 20 in the front-rear direction means the distance between the contact points of adjacent fulcrum guides 20 in the front-rear direction when the contact point is the contact point of the fulcrum guide 20 with the wire Y.

Each 1 st thread-dividing guide 91a is a thread guide to which a plurality of threads Y of the lambda thread guide 53 in the swing position are hooked on an upstream side of the lambda thread guide 53 in the thread traveling direction and a downstream side of the fulcrum thread guides 20 in the thread traveling direction. Each 1 st thread-dividing guide 91a is a plate-like member having a surface substantially parallel to the horizontal plane, for example. Each 1 st thread-divider thread guide 91a has a concave shape opening toward the rear side.

The rotation shaft 91b extends in the front-rear direction. The 1 st yarn separator 91 is rotatable about a rotation shaft 91b, and is thereby swingable between a standby position (see fig. 9) and a delivery position (see fig. 11). The 1 st yarn separator 91 swings by being driven by a cylinder or the like, not shown, for example.

The 2 nd yarn separator 92 is configured to move the plurality of yarns Y delivered from the 1 st yarn separator 91 to a winding position for winding on the bobbin B. The 2 nd wire separator 92 is attached to the machine body 14, for example. The 2 nd wire separator 92 may be attached to a member other than the machine body 14. As shown in fig. 9, the 2 nd wire separator 92 includes a plurality of 2 nd wire separator guides 92a, a rotation shaft 91b, and a driving mechanism 92c.

The plurality of 2 nd wire separator guides 92a are arranged in the front-rear direction (not shown). The pitch of the adjacent 2 nd wire separator guides 92a in the front-rear direction is substantially the same as the pitch of the adjacent 1 st wire separator guides 91a in the front-rear direction. Further, the distance between the adjacent 2 nd wire separator guides 92a in the front-rear direction means the distance between the contact points of the adjacent 2 nd wire separator guides 92a in the front-rear direction when the contact point is the contact point of the 2 nd wire separator guide 92a with the wire Y.

Each of the 2 nd wire separator guides 92a is, for example, a plate-like member having a surface intersecting with a horizontal plane. Each of the 2 nd wire separator guides 92a has a concave shape opening toward the rear side.

The rotation shaft 92b extends in the front-rear direction. The 2 nd wire separator 92 is rotatable about the rotation shaft 91b, and is thereby swingable between a standby position (see fig. 9), a delivery position (see fig. 11), and a wire winding position (see fig. 13). The 2 nd wire separator guide 92a swings by being driven by a driving mechanism 92 c. The driving mechanism 92c includes, for example, a cylinder and a piston.

(Order of hanging)

Next, a procedure for hooking the yarn Y to the plurality of fulcrum guides 20 using the yarn hooking member 30 will be described below. In the following description, the procedure in which the operator operates the suction gun 80 to hook the plurality of filaments Y spun from the spinning device 2 to the 1 st godet 3 and the 2 nd godet 4 is omitted. In the present embodiment, the operator operates the suction gun 80 to hang the yarn in the working space W of the plurality of fulcrum guides 20, and is located on the front side in the front-rear direction of the bobbin holder 13 (see fig. 1). In other words, the working space W is located closer to the wire contacting portion 51 in the front-rear direction than the front-rear direction of the bobbin holder 13.

First, before threading the yarn onto the fulcrum guides 20, the control device 6 moves the fulcrum guides 20 to the approaching position (see fig. 3). The driving mechanism 40 moves the yarn hanging member 30 to a yarn hanging position (not shown) which is a position on the front side of the forefront fulcrum guide 20 and on the right side of the fulcrum guides 20. Next, the operator operates the suction gun 80 to hook the plurality of wires Y in the state of being hooked on the 2 nd godet 4 at the rear side position to the plurality of holding grooves 31 of the yarn hooking member 30 at the yarn hooking position.

Next, the driving mechanism 40 moves the yarn hooking member 30 to the yarn hooking start position (see the two-dot chain line in fig. 5). Next, as shown in fig. 8, the operator moves the suction gun 80 to a position on the front side of the sheet metal member 50 below the wire contact portion 51, and brings the plurality of wires Y sucked and held by the suction gun 80 into contact with the wire contact portion 51. At this time, the plurality of wires Y are preferably brought into contact with the wire contact portion 51 at a position on the right side of the substantially central portion.

In a state where the plurality of wires Y sucked and held by the suction gun 80 are brought into contact with the wire contact portion 51, the driving mechanism 40 moves the wire member 30 from the wire-hanging start position to the wire-hanging end position (see the solid line of fig. 5). This completes the delivery of the plurality of wires Y from the wire member 30 to the plurality of fulcrum guides 20. That is, the threading to the plurality of fulcrum guides 20 ends.

After the completion of the delivery of the plurality of wires Y from the wire hanging member 30 to the plurality of fulcrum guides 20, the operator operates the suction gun 80 to separate the plurality of wires Y from the wire contacting portion 51. Specifically, the operator moves the suction gun 80 positioned below the wire contact portion 51 in front of the sheet metal member 50 further to the left, and separates the plurality of wires Y from the left end portion of the wire contact portion 51.

When the plurality of wires Y are separated from the left end portion of the wire contacting portion 51 by moving the suction gun 80, the operator stops the movement of the suction gun 80 leftward in the left-right direction. The operator moves down the suction gun 80 at substantially the same time as stopping the movement of the suction gun 80 in the lateral direction, and moves down the plurality of wires Y along the guide 54 formed on the left side surface of the sheet metal member 50.

In addition, according to the configuration of the present embodiment, the operator can move the plurality of wires Y downward by separating them from the wire contact portion 51 by moving only the suction gun 80 downward in the up-down direction. Specifically, by moving the suction gun 80 downward, the yarn Y naturally slides down along the inclination of the yarn contacting portion 51, and is guided directly under the lambda guide 53 along the guide portion 54 on the left side surface of the sheet metal member 50. In the present embodiment, the wire contact portions 51 formed on the upper surface are arranged symmetrically with respect to the metal plate member 50. Therefore, for example, the operator can simultaneously separate the plurality of wires Y from the wire contact portions 51 of the pair of sheet metal members 50 by moving the suction gun 80 that intensively sucks and holds the plurality of wires Y wound by the pair of winding portions 5, respectively, downward. Specifically, first, the operator brings each wire Y into contact with the wire contact portion 51 of each of the pair of sheet metal members 50 arranged in bilateral symmetry, and then arranges the suction gun 80 at a position substantially in the center in the lateral direction of the pair of winding portions 5 arranged in bilateral symmetry. In this state, the suction gun 80 is lowered directly downward, whereby the yarn Y can be simultaneously separated from the left and right yarn contacting portions 51.

Next, the operator hooks the plurality of wires Y that move downward along the guide 54 on the left side surface of the sheet metal member 50 onto the lambda wire guide 53 attached to the lower portion of the sheet metal member 50. The plurality of wires Y are hooked to the 1 st yarn separator 91 as they are hooked to the lambda yarn guide 53. Thereafter, the control device 6 controls driving of a swing mechanism, not shown, to swing the lambda guide 53, and appropriately swings the 1 st yarn splitter 91 and the 2 nd yarn splitter 92 to guide the plurality of yarns Y to the winding positions. Then, the plurality of yarns Y are wound around the bobbins B mounted on the bobbin holder 13, and a subsequent winding operation is performed.

The following describes an operation sequence from hooking the plurality of wires Y to the lambda guide 53 to winding the wires Y around the bobbin B after being guided to the winding positions. The plurality of 1 st thread-dividing thread guides 91a are moved to the approaching position in advance before thread is hung on each fulcrum thread guide 20, for example.

The plurality of wires Y are hooked to the 1 st wire separator guides 91a of the 1 st wire separator 91 as they are hooked to the lambda wire guide 53. Specifically, the plurality of wires Y caught by the lambda wire guide 53 are caught by the plurality of fulcrum wire guides 20 on the upstream side of the lambda wire guide 53 in the wire advancing direction. The wires Y traveling between the lambda wire guides 53 and the fulcrum wire guides 20 are caught by the 1 st wire divider wire guides 91a (see fig. 10) at the approaching positions between the lambda wire guides 53 and the fulcrum wire guides 20. When the plurality of wires Y are caught by the 1 st thread-dividing guides 91a, the plurality of 1 st thread-dividing guides 91a are moved to the separating position by a linear slider, not shown.

Next, the control device 6 controls driving of a swing mechanism (not shown), and thereby swings the lambda wire guide 53 to a swing position about the rotation shaft 53a (see fig. 11). Further, the control device 6 controls driving of a cylinder (not shown) to swing the 1 st wire separator 91 from the standby position to the bonding position (see fig. 11). The control device 6 controls driving of the driving mechanism 92c to swing the 2 nd wire separator 92 from the standby position to the joint position (see fig. 11). The 1 st yarn separator 91 is driven by a cylinder (not shown) configured to be capable of switching the stroke to two stages, and swings to acquire either one of the standby position and the delivery position. That is, the 1 st yarn separator 91 is restricted from swinging beyond the delivery position. The 2 nd wire separator 92 is restricted from swinging beyond the delivery position by a stopper not shown.

When the 1 st thread splitter 91 swings to the delivery position and the 2 nd thread splitter 92 swings to the delivery position, the respective threads Y are delivered from the 1 st thread splitter guides 91a to the 2 nd thread splitter guides 92 a. Specifically, when the 1 st yarn splitter 91 swings to the delivery position and the 2 nd yarn splitter 92 swings to the delivery position, each yarn Y is temporarily caught by both the 1 st yarn splitter guide 91a and the 2 nd yarn splitter guide 92 a. In this state, by returning the 1 st thread separator 91 to the standby position, each thread Y is separated from each 1 st thread separator guide 91a, and is caught only by each 2 nd thread separator guide 92 a. As described above, the transfer of the plurality of yarns Y from the 1 st yarn separator 91 to the 2 nd yarn separator 92 is completed. The lambda guide 53 continuously takes the swing position during the winding operation of winding the yarn Y onto the bobbin B mounted on the bobbin holder 13.

Next, the control device 6 controls the driving of the driving mechanism 92c to move the 2 nd wire separator 92 to a predetermined position between the standby position and the delivery position (see fig. 12). More specifically, the control device 6 moves the 2 nd wire separator 92 to a position between the standby position and the wire winding position and near the rotation center of the turntable 12 (see fig. 12). Next, the control device 6 rotates the turntable 12 to move the bobbin holder 13 on which the plurality of bobbins B of the unreeled yarn Y are mounted to the winding position (see solid arrows in fig. 12). At this time, the 2 nd wire divider 92 is at the predetermined position, and the lambda wire guide 53 is at the swing position. Therefore, the plurality of wires Y traveling between the 2 nd wire separator 92 and the lambda wire guide 53 are located near the rotation center of the turntable 12, that is, near the center of the rotation orbit of the two bobbin holders 13. This can prevent the bobbin holder 13 from coming into contact with the plurality of threads Y.

When the bobbin holder 13 reaches the winding position, the control device 6 controls the driving of the driving mechanism 92c to move the 2 nd yarn separator 92 to the yarn winding position (see fig. 13). When the bobbin holder 13 reaches the winding position, the bobbin holder 13 is restricted from swinging beyond the thread winding position by a stopper not shown. Thereby, the plurality of wires Y hooked to the 2 nd wire separator guides 92a are guided to the winding positions determined for the respective bobbins B. Each yarn Y guided to each winding position is wound around each bobbin B. Specifically, a groove and a hook are formed along the circumferential surface at the end of each bobbin B, and the yarn Y guided to the winding position is caught by the hook as it contacts the rotating bobbin B. Thereby, each yarn Y is wound around each bobbin B.

(Effect)

The spinning machine 1 of the present embodiment is configured to hang a yarn on a plurality of fulcrum guides 20 by moving a yarn hanging member 30 relative to the fulcrum guides 20 in a state in which a plurality of yarns Y held by suction by a suction gun 80 are held by the yarn hanging member 30, and the spinning machine 1 includes a yarn contacting portion 51 arranged at a position where the plurality of yarns Y traveling between the yarn hanging member 30 and the suction gun 80 can contact. According to the present embodiment, by bringing the plurality of wires Y sucked by the suction gun 80 into contact with the wire contact portion 51 between the suction gun 80 and the wire hanging member 30, it is possible to suppress the wire from swinging and propagating to the wire hanging member 30 due to the air flow generated in the suction gun 80. Accordingly, the plurality of wires Y held by the wire hanging member 30 can be delivered to the fulcrum guides 20 while the wire swing is suppressed. Accordingly, the yarn can be appropriately fed from the yarn feeding member 30 to the yarn guide 20 having a plurality of fulcrums.

In the present embodiment, the yarn hanging to the plurality of fulcrum guides 20 is performed in the order of the rear side (one side) to the front side (the other side) in the front-rear direction (the arrangement direction), and the yarn contacting portion 51 is located at a position closer to the other side than the fulcrum guide 20 located at the forefront side (the other side) in the front-rear direction (the arrangement direction). If the yarn hooking member 30 passes over the yarn contacting portion 51 in the front-rear direction (arrangement direction) while being hooked on the yarn guides 20 at the plurality of fulcra, the plurality of yarns Y may be separated from the yarn contacting portion 51 depending on the positional relationship between the yarn contacting portion 51 and the suction gun 80. In order to prevent this, the position of the suction gun 80 needs to be adjusted, but depending on the configuration of the device, there are cases where the position where the suction gun 80 can be placed is limited due to the presence of other components or the like. According to the present embodiment, regardless of the positional relationship between the wire contact portion 51 and the suction gun 80, the wire hanging member 30 does not pass over the wire contact portion 51 in the front-rear direction (arrangement direction) while hanging wires to the plurality of fulcrum guides 20. Therefore, the plurality of wires Y can be prevented from coming off the wire contact portion 51 in the middle of the wire hanging to the plurality of fulcrum guides 20.

In the present embodiment, the wire contact portion 51 has a shape extending in the extending direction. Therefore, the plurality of wires Y are easily brought into contact with the wire contact portion 51 extending in the extending direction. In the present embodiment, the wire contact portion 51 is inclined such that the left (one side) end portion in the extending direction of the wire contact portion 51 is lower than the right (other side) end portion. After the completion of the delivery of the plurality of wires Y from the yarn hanging member 30 to the fulcrum guides 20, the plurality of wires Y are separated from the wire contact portion 51 in order to transfer to the step of winding the wires Y around the bobbin B mounted on the bobbin holder 13. According to the present embodiment, the plurality of wires Y can be moved in a direction from the right (other side) end portion to the left (one side) end portion of the wire contact portion 51 in the extending direction so as to slide on the wire contact portion 51 by the action of gravity. This reduces the force required to move the plurality of wires Y, and enables the plurality of wires Y to be smoothly separated from the wire contact portion 51.

Further, in the present embodiment, the bobbin holder 13 is disposed on the left side (one side) of the wire contact portion 51 in the left-right direction (extending direction of the wire contact portion 51). According to the present embodiment, when the plurality of wires Y are moved downward along the wire contact portion 51 and separated from the wire contact portion 51 in the left-right direction at a position on the left side of the wire contact portion 51, the plurality of wires Y are positioned closer to the bobbin holder 13 than the wire contact portion 51. Accordingly, the plurality of wires Y separated from the wire contact portion 51 can be moved directly to the position of the bobbin holder 13 without passing over the wire contact portion 51 in the left-right direction. Accordingly, after the completion of the delivery of the plurality of wires Y from the yarn hooking member 30 to the fulcrum guides 20, the process can smoothly transition to the process of winding each wire Y around the bobbin B mounted on the bobbin holder 13.

In the present embodiment, the plurality of wires Y move toward the left (one side) end of the wire contact portion 51 in the extending direction while being in contact with the wire contact portion 51. The spinning machine 1 of the present embodiment further includes a drop prevention portion 52, and the drop prevention portion 52 prevents the plurality of threads Y from dropping off from the right end portion of the thread contacting portion 51 in the extending direction. According to the present embodiment, the plurality of wires Y in contact with the wire contact portion 51 can be prevented from accidentally coming off from the right end portion of the wire contact portion 51.

In the present embodiment, the thread contacting portion 51 has a shape in which the plurality of threads Y can be contacted while the threads are being hung from the thread hanging member 30 to the plurality of fulcrum guides 20. According to the present embodiment, the plurality of wires Y can be brought into continuous contact with the wire contact portion 51 while the wires are being hung from the wire hanging member 30 to the respective fulcrum guides 20. That is, it is possible to avoid that a part or all of the plurality of wires Y are separated from the wire contact portion 51 while the wires are being fed from the wire feeding member 30 to the fulcrum guides 20. Accordingly, the plurality of wires Y held by the wire hanging member 30 are delivered to the fulcrum guide 20 while the wire swing is reliably suppressed. This makes it possible to more appropriately perform threading from the threading member 30 to the plurality of fulcrum guides 20.

In the present embodiment, the yarn contacting portion 51 is a contact surface with which the plurality of yarns Y can be in surface contact. The larger the contact area between the plurality of wires Y and the wire contact portion 51 is, the smaller the load each wire Y receives from the wire contact portion 51. According to the present embodiment, by bringing the plurality of wires Y into surface contact with the wire contact portion 51, the contact area between each wire Y and the wire contact portion 51 increases. Therefore, the load received by the plurality of wires Y can be reduced as compared with the case where the plurality of wires Y are brought into contact with the edge-shaped wire contact portion 51, even if the plurality of wires Y are in point contact with the wire contact portion 51. This can suppress breakage and deflection of the plurality of wires Y due to contact between the plurality of wires Y and the wire contact portion 51.

Further, the present embodiment includes a lambda guide 53 (winding guide) for guiding the plurality of wires Y hooked to the plurality of fulcrum guides 20 to winding positions for winding the plurality of wires Y around the plurality of bobbins B mounted on the bobbin holder 13. The wire contact 51 is integrally formed with a lambda wire guide 53. According to the present embodiment, after the completion of the delivery of the plurality of wires Y from the yarn hooking member 30 to the respective fulcrum guides 20, the plurality of wires Y separated from the wire contacting portion 51 can be directly hooked on the lambda guide 53 integrally formed with the wire contacting portion 51. Therefore, the process can smoothly transition to the process of winding each yarn Y around the bobbin B mounted on the bobbin holder 13.

In the present embodiment, a lambda guide 53 is disposed below the wire contact portion 51. The spinning tractor 1 of the present embodiment further includes a guide 54, and the guide 54 extends in the up-down direction to guide the plurality of yarns Y from the yarn contacting portion 51 to the lambda yarn guide 53. The guide portion 54 can smoothly guide the plurality of wires Y separated from the wire contact portion 51 to the lambda guide 53. Therefore, after the completion of the delivery of the plurality of wires Y from the yarn hooking member 30 to the fulcrum guides 20, the process can be smoothly shifted to the process of winding the wires Y around the bobbin B mounted on the bobbin holder 13.

In the present embodiment, a driving mechanism 40 is provided, and the driving mechanism 40 moves the yarn hooking member 30 between a yarn hooking start position at which yarn hooking to the plurality of fulcrum guides 20 is started and a yarn hooking end position at which yarn hooking to the plurality of fulcrum guides 20 is ended. In the structure in which the yarn hanging member 30 is moved by the driving mechanism 40, when yarn swinging of the plurality of yarns Y held by the yarn hanging member 30 occurs, the position of the yarn hanging member 30 cannot be finely adjusted to correct the position of the yarn Y delivered to the fulcrum guide 20. In this configuration, it is more effective to provide the wire contact portion 51.

In the present embodiment, the operating space W for the operator to hang the yarn on the plurality of fulcrum guides 20 by operating the suction gun 80 is located at a position closer to the yarn contacting portion 51 in the front-rear direction (alignment direction) than the front side (other side) and the rear side (one side) of the bobbin holder 13. According to the present embodiment, the operator can perform work in a wide space around which the bobbin holder 13 and the fulcrum guide 20 are not disposed.

Further, in the present embodiment, the yarn hanging member 30 has a plurality of holding grooves 31 for holding 1 yarn Y, and the plurality of holding grooves 31 are arranged in parallel with the extending direction. According to the present embodiment, the running surface of the yarn Y passing through the yarn path of each yarn Y is maintained in a state parallel to the extending direction until the plurality of yarns Y hooked to the plurality of holding grooves 31 of the yarn hooking member 30 reach the yarn contacting portion 51. In other words, the running surface of the plurality of wires Y running between the plurality of holding grooves 31 and the wire contacting portion 51 is not twisted. Accordingly, the bending angle of the plurality of wires Y in contact with the wire contact portion 51 becomes uniform among the wires Y, and the quality of the wires affected by the bending angle can be made uniform among the wires Y.

In the present embodiment, the yarn hooking member 30 is disposed downstream of the plurality of fulcrum guides 20 in the yarn traveling direction. The plurality of wires Y sucked by the suction gun 80 are gathered to the suction gun 80. That is, the pitch of the plurality of wires Y held by the wire member 30 becomes narrower toward the suction gun 80 on the downstream side of the wire member 30. In this regard, in the present embodiment, the yarn hanging member 30 is disposed downstream of the fulcrum guide 20 in the yarn traveling direction. Therefore, the plurality of wires Y having the narrowed pitch on the downstream side of the yarn hanging member 30 can be hooked on the fulcrum guide 20 without being hooked on the fulcrum guide 20, but the plurality of wires Y having the uniform pitch can be hooked on the fulcrum guide 20. Thus, in the configuration of the present invention, the yarn is easily suspended from the fulcrum guide 20, as compared with the case where the yarn suspending member 30 is disposed on the upstream side of the fulcrum guide 20.

(Modification)

A modified example in which the above-described embodiment is modified will be described below. However, the same reference numerals are given to the same components as those of the above embodiments, and the description thereof will be omitted appropriately.

In the above embodiment, the extending direction of the wire contact portion 51 is parallel to the left-right direction when viewed from the up-down direction. However, the extending direction of the wire contact portion 51 may be a direction intersecting the left-right direction when viewed from the up-down direction.

In the above embodiment, the wire contact portion 51 is inclined such that the left (one side) end portion in the extending direction is lower than the right (other side) end portion. However, the wire contact portion 51 may be bent such that the left (one side) end portion is lower than the right (other side) end portion in the extending direction. However, the structure in which the wire contact portion 51 is bent does not include a structure in which a portion between the left end portion and the right end portion of the wire contact portion 51 is recessed below both end portions. The wire contact portion 51 may extend in the horizontal direction.

In the above embodiment, the drop-off preventing portion 52 prevents the plurality of wires Y from dropping off from the right (other) side end portion of the wire contacting portion 51 inclined so that the left (one) side end portion in the extending direction is lower than the right (other) side end portion. However, the drop-off preventing portion 52 may prevent the plurality of wires Y from dropping off from the right (other) side end portion of the wire contacting portion 51 extending in the horizontal direction. In this case, the plurality of wires Y move toward the left (one side) end of the wire contact portion 51 in the extending direction while contacting the wire contact portion 51. The drop-off preventing portion 52 may not be formed.

In the above embodiment, the bobbin holder 13 is located on the left side (one side) of the wire contact portion 51 in the left-right direction (or extending direction). However, the bobbin holder 13 may be positioned on the left (one side) of the wire contact portion 51 inclined so that the left (one side) end portion in the extending direction is lower than the right (other side) end portion in the left-right direction (or extending direction).

In the above embodiment, the wire contact portion 51 and the drop-off preventing portion 52 are formed in the sheet metal member 50. However, the wire contact portion 51 and the drop preventing portion 52 may be members different from the sheet metal member 50. Further, in the above embodiment, the wire contact portion 51 is integrally formed with the lambda wire guide 53. The wire contact portion 51 and the lambda wire guide 53 may not be integrally formed. That is, the wire contact portion 51 and the lambda wire guide 53 may be separately disposed.

In the above embodiment, the wire contact portion 51 is formed on the upper surface of the metal plate member 50. The wire contact portion 51 has a contact surface rounded when viewed from the left-right direction. However, the wire contact portion may be formed on the upper peripheral surface of the rod-like member extending in a predetermined extending direction, for example. In this case, the upper peripheral surface of the rod-like member as the wire contact portion is a contact surface with which the plurality of wires Y can be in surface contact.

In the above embodiment, the wire contacting portion 51 has the following shape as a shape that can be contacted by the plurality of wires Y during the wire hanging from the wire hanging member 30 to the plurality of fulcrum guides 20. That is, the length of the wire contact portion 51 in the extending direction is a length sufficient to prevent the plurality of wires Y moving along with the yarn hanging from falling off from the left end portion of the wire contact portion 51 during yarn hanging from the yarn hanging member 30 to the plurality of fulcrum guides 20. However, the wire contacting portion 51 may have a shape different from the above-described embodiment as a shape that enables the plurality of wires Y to contact each other while the wires are being suspended from the yarn suspending member 30 to the plurality of fulcrum guides 20. For example, a2 nd drop preventing portion may be formed on the upper surface of the metal plate member 50, and the 2 nd drop preventing portion may prevent the plurality of wires Y from dropping from the left end portion of the wire contact portion 51 in the left-right direction. Thus, the thread contacting portion 51 has a shape that allows the plurality of threads Y to contact while the threads are being hung from the thread hanging member 30 to the plurality of fulcrum guides 20. The 2 nd fall-off preventing portion has the same structure as the fall-off preventing portion 51 of the above embodiment, for example. In this case, the 2 nd drop preventing portion is preferably formed detachably on the upper surface of the metal plate member 50. Thus, by detaching the 2 nd drop prevention portion, the 2 nd drop prevention portion does not become an obstacle when the plurality of wires Y are separated from the wire contact portion 51 and guided to the position where the lambda wire guide 53 is located.

In the above embodiment, when the plurality of wires Y are hooked to the yarn hooking member 30 at the yarn hooking position, the plurality of wires Y are not brought into contact with the wire contacting portion 51. However, when the plurality of wires Y are hooked to the yarn hooking member 30 at the yarn hooking position, the plurality of wires Y may be brought into contact with the wire contact portion 51. This can suppress the yarn swing when the yarn Y is hooked to the yarn hooking member 30.

In the above embodiment, the driving mechanism 40 is configured to move the wire hanging member 30 when the wire is hung from the wire hanging member 30 to the plurality of fulcrum guides 20. However, the operator may manually move the wire hanging member 30 when hanging the wire from the wire hanging member 30 to the plurality of fulcrum guides 20.

In the above embodiment, the yarn hanging member 30 is moved from the yarn hanging start position to the yarn hanging end position, whereby the plurality of yarns Y are delivered from the yarn hanging member 30 to the plurality of fulcrum guides 20. However, for example, the plurality of fulcrum guides 20 may be moved from the front to the rear in the front-rear direction (arrangement direction), and the plurality of wires Y may be transferred from the wire hanging member 30 to the plurality of fulcrum guides 20. In this case, as in the above-described embodiment, the threading to the plurality of fulcrum guides 20 is performed in the order from the rear side (one side) to the front side (the other side) in the front-rear direction (the arrangement direction). In this case, the wire contact portion 51 may not be disposed further toward the front side (the other side) than the fulcrum guide 20 disposed at the forefront side (the other side) in the front-rear direction (the arrangement direction). In addition, the "moving the wire member 30 relative to the plurality of fulcrum guides 20" of the present invention includes a configuration in which the wire member 30 is moved relative to the plurality of fulcrum guides 20 by moving the plurality of fulcrum guides 20, as well as a configuration in which the wire member 30 itself is moved.

In the above embodiment, the guide portion 54 extends in the vertical direction. However, the guide 54 may extend in a direction inclined with respect to the vertical direction. The spinning tractor 1 may not have the guide 54.

In the above embodiment, the plurality of holding grooves 31 are arranged in parallel to the extending direction of the wire contacting portion 51. However, the plurality of holding grooves 31 may not be arranged in parallel with the extending direction of the wire contacting portion 51.

In the above embodiment, the spinning machine 1 is provided with the pair of winding sections 5, but is not limited to this. The spinning machine 1 may include, for example, only one winding portion 5 of the pair of winding portions 5.

The present invention is not limited to the spinning machine 1, and can be applied to various yarn winding machines configured to wind a plurality of yarns Y.

In the above embodiment, the yarn hanging member 30 is arranged downstream of the plurality of fulcrum guides 20 in the yarn traveling direction. However, the yarn hanging member 30 may be disposed upstream of the plurality of fulcrum guides 20 in the yarn advancing direction.
