  Each of the two yarn winding units includes a plurality of yarn guides and guide rails extending in a direction inclined with respect to the arrangement direction of these yarn guides (the axial direction of the bobbin holder). In the present invention, “inclined with respect to the arrangement direction” means that it intersects the arrangement direction at an angle of less than 90 degrees, and the guide rail is parallel to the arrangement direction or the arrangement direction. Orthogonal features are excluded. On the other hand, each of the two yarn holding portions of the yarn hooking member holds a plurality of yarns wound by the corresponding yarn winding portion in a state where the yarns are separated. The two thread holding portions are supported so as to be able to approach / separate.

  In a state where a plurality of yarns are held in each yarn holding portion, the two yarn holding portions are slidably engaged with the guide rails of the corresponding yarn winding portions. Further, the two guide rails extend so as to be inclined opposite to each other with respect to the arrangement direction. In this state, the yarn hooking member is moved in the direction in which the yarn guides are arranged. Here, since the two yarn holding portions are supported by the support portion so as to be able to approach / separate, the two yarn holding portions are inclined with respect to the arrangement direction of the yarn guides along the guide rail while being separated from each other. Move to. As a result, the plurality of yarns held in the respective yarn holding portions are hung on the plurality of yarn guides of the corresponding yarn winding portions. According to the present invention, the yarn hooking operation is simplified because the yarn hooking member can be simultaneously hooked on the yarn guides of the two yarn winding portions on both sides only by moving the yarn hooking member once in the arrangement direction.

  A yarn winding machine according to a second invention is characterized in that, in the first invention, the yarn hooking member has a handle connected to the support portion and extending in the arrangement direction.

  When the number of yarn guides arranged (that is, the number of bobbins) is large, the yarn hooking member needs to be moved a long distance in the arrangement direction when threading the yarn guide. In this regard, in the present invention, since the yarn hooking member has a handle extending forward from the support portion, it is easy to grip the handle and move the yarn hooking member far.

  In the yarn winding machine according to a third aspect of the present invention, in the first or second aspect of the invention, the yarn holding portion is an engagement portion that engages with the guide rail at an outer end in a direction orthogonal to the arrangement direction. It is characterized by having.

  When there is an engaging portion at the outer end of each yarn holding portion, when the yarn hooking member moves in the arrangement direction, the yarn holding portion easily moves in a direction orthogonal to the arrangement direction.

  In a state where a plurality of yarns are held, each of the two yarn holding portions is slidably engaged with a guide rail of a corresponding yarn winding portion. In this state, the yarn hooking member is moved in the arrangement direction of the yarn guides. Here, since the two yarn holding portions are supported by the support portion so as to be able to approach / separate, the two yarn holding portions move along the guide rail while being separated from each other. As a result, the plurality of yarns held in the respective yarn holding portions are hung on the plurality of yarn guides of the corresponding yarn winding portions.

A yarn winding method for a yarn winding machine according to a sixth aspect of the present invention is the yarn winding method according to any one of the first to fourth yarn winding machines, wherein the yarn guide is used to thread the yarn guides of the two yarn winding sections.

  Next, an embodiment of the present invention will be described. 1 and 2 are defined as front / rear / left / right / up / down directions of the spinning take-up apparatus, and these direction words will be used below as appropriate.

(Schematic configuration of the spinning take-up device)
As shown in FIGS. 1 and 2, the spinning take-up device 1 includes two godet rollers 3 and 4, a yarn winding machine 5, a control device 6, and the like.

  A spinning machine 2 is disposed above the spinning take-up device 1. The spinning machine 2 spins synthetic yarn Y from a plurality of spinnerets (not shown).

  The two godet rollers 3 and 4 are arranged below the spinning machine 2 in a posture in which the axial direction is parallel to the left-right direction. The yarn Y spun from the spinning machine 2 is wound around the godet roller 3 and the godet roller 4 in this order. The two godet rollers 3 and 4 are supported by a long support member 7 that extends rearward and obliquely upward from a position above the front end of the yarn winding machine 5.

  The godet roller 3 on the upstream side in the yarn traveling direction is attached to the front end portion of the support member 7. The other godet roller 4 is attached to the support member 7 so as to be movable along its length. Further, the position of the godet roller 4 is switched between a front position indicated by a two-dot chain line and a rear position indicated by a solid line in FIG. As will be described later, the front side position of the godet roller 4 is a position at the time of yarn hooking, and the rear side position is a position at the time of yarn winding by the yarn winding machine 5.

  The two godet rollers 3 and 4 are each driven to rotate by a drive motor (not shown). A plurality of yarns Y spun from the spinning machine 2 are sent to the yarn winding machine 5 by the two godet rollers 3 and 4. As shown in FIG. 2, a yarn regulating guide 8 is provided on the upstream side of the godet roller 3 in the yarn traveling direction, and a yarn regulating guide 9 is also provided on the upstream side of the godet roller 4 in the yarn traveling direction.

  The yarn winding machine 5 includes two winding units 10 (corresponding to the yarn winding unit of the present invention). The two winding units 10 are arranged in the left-right direction and sandwich the yarn paths of the plurality of yarns Y fed from the upper godet rollers 3 and 4. The two winding units 10 are arranged symmetrically. A plurality of yarns Y spun from the spinning machine 2 are sent to two winding units 10 separately. For example, when 24 yarns Y are sent from the spinning machine 2, half of the 12 yarns are taken up by the left winding unit 10, and the remaining 12 yarns are taken up by the right winding unit 10. It is done.

  Each winding unit 10 includes a support frame 11, a turret 12, and two bobbin holders 13. The support frame 11 is cantilevered on the machine base 14 in a horizontal posture. The turret 12 is a disk-shaped member and is attached to the machine base 14 so as to be rotatable. Two bobbin holders 13 extending in the front-rear direction are supported on the turret 12 in a cantilever state. A plurality (for example, twelve) of bobbins B are attached to each bobbin holder 13 along the axial direction. Each bobbin holder 13 is rotationally driven by a motor (not shown). When the turret 12 rotates, the positions of the two bobbin holders 13 supported by the turret 12 are switched up and down.

  Further, each winding unit 10 includes a plurality of guide units 15, a plurality of traverse guides 16, and contact rollers 17.

  As shown in FIGS. 1 to 3, a guide support 19 that is long in the front-rear direction is provided on the upper portion of the support frame 11. A guide rail 20 extending in the front-rear direction is fixed to the guide support body 19. A plurality of guide units 15 are attached to the guide rail 20 so as to be movable in the front-rear direction.

  The plurality of guide units 15 have a plurality of fulcrum guides 21 (thread guides of the present invention) respectively corresponding to the plurality of bobbins B. The configuration of the guide unit 15 will be described in detail later.

  The plurality of traverse guides 16 are attached to the support frame 11 and are disposed below the plurality of guide units 15. The yarn Y hung on the fulcrum guide 21 of each guide unit 15 is traversed back and forth by the traverse guide 16 with the fulcrum guide 21 as a fulcrum. The traversed yarn Y is wound on a bobbin B mounted on a rotating bobbin holder 13, thereby forming a package P.

  The contact roller 17 is rotatably supported at the lower part of the support frame 11. The contact roller 17 rotates while applying a predetermined contact pressure to the package P when winding the yarn around the bobbin B, thereby adjusting the shape of the package P.

  When the fully wound package P is formed on the bobbin holder 13 in the upper position, the turret 12 rotates and the two bobbin holders 13 are switched. That is, the bobbin holder 13 located at the lower position moves to the upper position, and the yarn Y is wound around the bobbin B attached to the bobbin holder 13. Further, the bobbin holder 13 around which the full package P is wound moves to the lower position, and the full package P is removed at the lower position.

  The control device 6 shown in FIG. 2 is responsible for overall control of the spinning take-up device 1. Specifically, the control device 6 sends a control signal to each part of the spinning take-up device 1 such as a motor that drives the godet rollers 3 and 4, a lifting and lowering motor for the godet roller 4, and a control unit 18 of the yarn winding machine 5.

(Details of the guide unit)
As shown in FIGS. 3 and 4, each guide unit 15 includes a guide holding member 22, a fulcrum guide 21 attached to the guide holding member 22, an upper guide 23, and a lower guide 24.

  The guide holding member 22 is attached to the guide rail 20 so as to be movable in the front-rear direction. The guide holding member 22 is attached with an air cylinder (not shown) that drives the plurality of guide units 15 in the front-rear direction. Accordingly, the plurality of guide units 15 are gathered on the front end side so that the winding positions (see FIGS. 2 and 12) distributed in the front-rear direction are smaller than the winding positions in the front-rear direction. It is possible to move between the designated yarn hooking positions (see FIGS. 7 and 10).

  The fulcrum guide 21 has a cylindrical shape, and is attached to the guide holding member 22 so that its axial direction is parallel to the left-right direction. The fulcrum guide 21 is a guide that becomes a fulcrum when the yarn Y is traversed by the traverse guide 16. As shown in FIG. 2, the yarn Y is hung on the outer side surface of the fulcrum guide 21 for each of the plurality of fulcrum guides 21. That is, as shown in FIG. 4A, in the guide unit 15 (15a) located on the rear side, the thread Y is hung on the rear side surface of the fulcrum guide 21. Further, as shown in FIG. 4B, in the guide unit 15 (15 b) located on the front side, the yarn Y is hung on the front side surface of the fulcrum guide 21. As will be described in detail later, threading to the plurality of guide units 15 (fulcrum guides 21) is performed by moving all the threads Y from the rear to the front using the thread hooking member 26 (see FIG. 8). ).

  The upper guide 23 is a U-shaped guide disposed above the fulcrum guide 21 and is disposed such that the U-shaped opening faces rearward. The yarn Y threaded on the fulcrum guide 21 from behind enters the upper guide 23 from the opening. The upper guide 23 restricts the movement of the yarn Y in the left-right direction.

  Further, while moving all the yarns Y from the rear to the front, the rear side fulcrum guide 21 is hung on the rear side, and the front side fulcrum guide 21 is hung on the front side. The following points need to be noted. First, the guide unit 15a located on the rear side needs to be devised so that the yarn Y does not move forward relative to the fulcrum guide 21. On the other hand, in the guide unit 15b located on the front side, a device for turning the yarn Y that has moved from the rear in front of the fulcrum guide 21 is required.

  For this purpose, a lower guide 24 is disposed below each fulcrum guide 21. As shown in FIG. 4, the lower guide 24 is a hook-shaped guide having a hook-shaped tip. However, the direction of the lower guide 24 is different between the rear guide unit 15a and the front guide unit 15b.

  As shown in FIG. 4A, the lower guide 24 of the rear guide unit 15a has a hook-shaped tip portion facing the rear side. As a result, the yarn Y that has moved from the rear side is restricted from moving outside by the hook-shaped tip after entering the lower guide 24. On the other hand, as shown in FIG. 4B, the lower guide 24 of the front guide unit 15b has a hook-shaped tip portion facing the front side. The yarn Y that has moved from the rear side moves forward around the fulcrum guide 21 along the outer edge of the lower guide 24 and then enters the lower guide 24.

  As shown in FIGS. 1 and 3, the plurality of guide units 15 of the two winding units 10 arranged in two rows are arranged so that the tips of the fulcrum guides 21 face inward. Then, by moving a yarn hooking member 26, which will be described later, between the two winding units 10, the yarn hooking can be performed simultaneously on all of the guide units 15 arranged in two rows. Yes.

(Configuration for thread hanging)
Next, a configuration for applying a plurality of yarns Y to a plurality of guide units 15 will be described. In FIG. 5, in order to clearly show the guide rail 25, the plurality of guide units 15 arranged on the guide rail 25 and the yarn hooking member 26 are indicated by phantom lines.

  As shown in FIGS. 3 and 5, each winding unit 10 includes a guide rail 25 that extends with an inclination with respect to the front-rear direction, which is the arrangement direction of the guide units 15. The guide rail 25 is fixed to a portion of the guide support body 19 that is lower than the plurality of guide units 15 (the other side in FIG. 5). The rear end portion of the guide rail is located behind the plurality of guide units 15 and is exposed from the plurality of guide units 15. The guide rails 25 of the two winding units 10 are symmetrically arranged and are inclined opposite to each other with respect to the front-rear direction. In other words, the two guide rails 25 are inclined to the outside in the front-rear direction so as to spread away from each other toward the front side. Each guide rail 25 is formed with a guide groove 25a extending along the extending direction.

  As shown in FIG. 6, the yarn hooking member 26 has two yarn holding portions 30 (30a, 30b), a support portion 31, and a handle 32. The two yarn holding portions 30 correspond to the two right and left winding units 10, respectively. Each of the two yarn holding portions 30 is formed with a plurality of splitting grooves 33 that hold a plurality of yarns Y wound around the corresponding winding unit 10 in a split state. As shown in FIG. 6A, the plurality of splitting grooves 33 formed in the two yarn holding portions 30 are arranged so as to have a fan shape that spreads from the tip side toward the back side as a whole. . Moreover, the thread | yarn holding | maintenance part 30 has the two engaging parts 34 which protrude in the back side (the paper surface other side of FIG. 6) of the thread | yarn holding | maintenance part 30 in the outer edge part in the left-right direction. The engaging portion 34 is slidably engaged with the guide groove 25a of the guide rail 25. Thereby, the two yarn holding portions 30 of the yarn hooking member 26 can be attached and detached at least from the rear end portion of the guide rail 25.

  The support part 31 has a guide part 35 fixed to the base end part of the left thread holding part 30a and a slide part 36 fixed to the base end part of the right thread holding part 30b. A sliding portion 36 is engaged with the guide portion 35 so as to be slidable left and right. Thereby, the right thread holding part 30b is movable relative to the left thread holding part 30a. That is, between the state in which the two left and right thread holding portions 30 in FIG. 6A are in contact with each other and the state in which the two thread holding portions 30 in FIG. Is configured to be movable relative to the left and right.

  The handle 32 is a rod-shaped member extending in the front-rear direction. The distal end portion of the handle 32 is connected to the guide portion 35.

  As will be described later, when threading the guide unit 15, the thread Y wound by the two winding units 10 is held in the two thread holding portions 30 of the thread hooking member 26, respectively. As shown in FIG. 2, the yarn hooking member 26 is moved forward between the two winding units 10.

(Threading work)
Next, the yarn hooking operation for hanging the plurality of yarns Y spun from the spinning machine 2 on the spinning take-up device 1 and the operation of the spinning take-up device 1 at that time will be described with reference to FIGS. To do.

  At the time of the yarn hooking operation, the operator stands on the front side of the yarn winding machine 5 and performs the operation. First, an operator inputs a command for preparing for threading from an operation unit (not shown) of the spinning take-up device 1.

  When the yarn threading preparation command is input, the control device 6 causes the spinning take-up device 1 to perform the following yarn threading preparation operation. First, from the state where the godet roller 4 is in the rear position, the godet roller 4 is lowered by the elevating motor and moved to the front position near the godet roller 3. Further, all the guide units 15 are moved to the yarn hooking position by the air cylinder and are concentrated on the front side.

  When the yarn winding preparation operation of the spinning take-up device 1 is completed, the operator sucks and holds the plurality of yarns Y descending from the upper spinning machine 2 with the suction gun 40. At this time, all the yarns Y wound by the two winding units 10 (for example, 12 yarns per unit, a total of 24 yarns) are sucked by the suction gun 40. Further, the operator operates the suction gun 40 to sequentially apply the plurality of yarns Y to the two godet rollers 3 and 4 disposed close to each other above the front end portion of the yarn winding machine 5.

  When the yarn hooking on the two godet rollers 3 and 4 is finished, the plurality of yarns Y are hung on each of the plurality of guide units 15. Threading the guide unit 15 is performed using the threading member 26. First, the yarn hooking member 26 is removed from the guide rail 25 before the yarn is hooked onto the guide unit 15. In this state, the operator holds two yarns of the yarn hooking member 26 with respect to a plurality of yarns Y positioned between the godet roller 4 and the suction gun 40 in FIG. 7 while holding the handle 32 of the yarn hooking member 26. Insert the part 30 from the front. As a result, the plurality of yarns Y are inserted one by one into the plurality of splitting grooves 33 of the two yarn holding units 30, and are held in the yarn holding unit 30 in a state of being split (yarn holding step). ). At this time, since the plurality of yarns Y are sucked by the front suction gun 40, tension is applied to the yarn Y held by the yarn holding unit 30, and the yarn Y is freely transmitted from the splitting groove 33. There is no escape.

  Next, as shown in FIG. 8, the operator attaches the yarn hooking member 26 to the rear ends of the two guide rails 25. More specifically, the engaging portions 34 of the two yarn holding portions 30 of the yarn hooking member 26 are respectively engaged with the end portions on the rear side of the plurality of guide units 15 of the guide grooves 25 a of the two guide rails 25. (Engagement step). As shown in FIG. 9, after engaging the guide rail 25, the operator holds the handle 32 and draws the yarn hooking member 26 toward the front side (front side). Here, the two thread holding portions 30 are supported by the support portion 31 so as to be relatively movable in the left-right direction. Therefore, on the lower side of the plurality of guide units 15, the two thread holding portions 30 respectively move along the two guide rails 25 that are inclined so as to spread forward while being separated from each other in the left-right direction.

  Each of the yarn holding portions 30 moves along the corresponding guide rail 25 in a direction inclined with respect to the arrangement direction of the guide units 15, so that a plurality of yarn holding portions 30 are held in a divided state. As shown in FIG. 10, the yarn Y is led to a plurality of guide units 15 arranged in a row and is hung (threading step). Further, the two yarn holding portions 30 of the yarn hooking member 26 move along the two guide rails 25, so that the yarn Y is hooked simultaneously on the left and right two rows of guide units 15.

  When the threading to the guide unit 15 is completed, the operator then inputs a winding preparation command from the operation unit of the spinning take-up device 1. When a winding preparation command is input, the control device 6 causes the spinning take-up device 1 to perform the following winding preparation operation. First, as shown in FIG. 11, the godet roller 4 is moved back and up from the front position to the rear position by the lifting motor. In addition, as shown in FIG. 12, the plurality of guide units 15 are moved from the yarn hooking position toward the winding position by the air cylinder and are separated from each other.

  In the present embodiment, the guide rails 25 of the two winding units 10 extend so as to be inclined opposite to each other with respect to the arrangement direction of the yarn Y guides (the axial direction of the bobbin holder 13). On the other hand, each of the two yarn holding portions 30 of the yarn hooking member 26 holds the plurality of yarns Y taken up by the corresponding yarn winding portion in a state of being divided. Further, the two thread holding portions 30 are supported so as to be relatively movable in a direction orthogonal to the arrangement direction. In other words, the two yarn holding portions 30 are supported by the support portion 31 so as to be able to approach / separate.

  In a state where a plurality of yarns Y are held in each yarn holding portion 30, the two yarn holding portions 30 are slidably engaged with the guide rails 25 of the corresponding winding units 10. In this state, when the yarn hooking member 26 is moved forward in the direction in which the two guide rails 25 expand, the two thread holding portions 30 move along the two guide rails 25 while moving in the left-right direction. Move each. As a result, the plurality of yarns Y held by the respective yarn holding portions 30 are hung on the plurality of guide units 15 of the corresponding winding unit 10. In this embodiment, since the yarn Y can be simultaneously hung on the guide units 15 of the two winding units 10 on both sides only by moving the yarn hooking member 26 once forward, the yarn hooking operation is simplified. .

  When the arrangement number of the guide units 15 (that is, the number of bobbins B) is large, it is necessary to move the yarn hooking member 26 by a long distance in the front-rear direction when threading. That is, it is necessary for the operator in front to move the yarn hooking member 26 to the far side.
