Description

[Technical Field]

[0001] The present invention relates to a yarn take-off device that takes up a plurality of yarns spun from a spinning device. [Background technology]

[0002] For example, Patent Document 1 discloses a spinning yarn take-up device that includes multiple yarn feed rollers that feed multiple yarns and multiple yarn dividing guides that are arranged immediately upstream of the multiple yarn feed rollers. Each yarn dividing guide is formed with multiple regulating portions that regulate the movement of the multiple yarns. In this spinning yarn take-up device, the yarn is threaded onto the multiple yarn feed rollers as follows.

[0003] First, the operator sucks and holds multiple yarns with a suction gun, and then, with the multiple yarns bundled together, threads them onto each yarn separation guide and each yarn feed roller in order from the upstream side in the yarn running direction. At this time, in each yarn separation guide, the multiple yarns bundled together are threaded together on one regulating section. After threading the yarns onto each yarn separation guide and each yarn feed roller is completed, the suction gun is temporarily placed on the floor.

[0004] Next, the operator uses the threading aid to thread the bundled yarns onto the restricting sections of each yarn separation guide. This allows the yarns to be properly separated and fed at the desired pitch by each yarn feed roller. The threading aid allows the operator to work without holding a suction gun, which is said to make threading easier. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-187324 Summary of the Invention [Problem to be solved by the invention]

[0006] The dimensions of the regulating portion of each yarn separation guide are quite small. Therefore, it is practically impossible to gather multiple yarns that are bundled together into a single regulating portion, which could damage the yarns or, in the worst case, cause them to break. Therefore, it is possible to separate the multiple yarns and thread them on several regulating portions before using the threading aid. However, this creates a problem in that the pitch of the multiple yarns becomes uneven upstream of the yarn separation guide in the yarn running direction, making it difficult for the threading aid to capture the multiple yarns.

[0007] The present invention has been made in view of the above problems, and has an object to provide a spun yarn take-up device that can easily perform a threading operation while minimizing damage to the yarn. [Means for solving the problem]

[0008] The present invention is a yarn take-up device comprising a yarn feed roller that feeds multiple yarns spun from a spinning device, and a yarn separating guide that is arranged upstream of the yarn feed roller in the yarn running direction and is formed with multiple regulating portions that regulate movement of the multiple yarns in the axial direction of the yarn feed roller, characterized in that the yarn separating guide is provided with a focusing guide that is formed with a focusing portion that can bundle the multiple yarns into one without getting caught in the multiple regulating portions.

[0009] In the present invention, by hooking multiple yarns on the converging portion of the converging guide before hooking them on the yarn separating guide, the pitch of the multiple yarns can be made approximately uniform upstream of the converging guide in the yarn running direction, making it easier to work with a threading aid. Furthermore, since there is no need to forcibly hook multiple yarns on one regulating portion of the yarn separating guide while still bundled together, damage to the yarns can be reduced. Therefore, according to the present invention, threading can be easily performed while reducing damage to the yarns.

[0010] In the present invention, another yarn feeding roller that feeds the plurality of yarns is disposed upstream of the yarn separation guide in the yarn running direction, and the direction in which the plurality of yarns are arranged may change between the other yarn feeding roller and the yarn separation guide.

[0011] In this case, the direction of the multiple yarns changes on the way from the other yarn feed roller to the yarn separation guide, making it more difficult to use the yarn threading aid. However, the multiple yarns can be bundled together by the bundling guide until just before they are threaded onto the yarn separation guide, making it easier to use the yarn threading aid.

[0012] In the present invention, a yarn regulation guide that regulates the movement of the multiple yarns is arranged upstream of the yarn separation guide in the yarn running direction, and the direction in which the multiple yarns are arranged changes between the yarn regulation guide and the yarn separation guide.

[0013] In this case, the direction of the multiple threads changes on the way from the thread control guide to the thread separation guide, making it more difficult to work with the threading aid. However, the multiple threads can be bundled together in the bundling guide until just before they are threaded onto the thread separation guide, making it easier to work with the threading aid.

[0014] In the present invention, the converging guide may be disposed upstream of the yarn separating guide in the yarn running direction.

[0015] The focusing guide may be disposed between the yarn dividing guide and the yarn feed roller in the yarn running direction. However, since the yarn dividing guide is disposed near the yarn feed roller, it may be difficult to dispose the focusing guide between the yarn dividing guide and the yarn feed roller. In this regard, if the focusing guide is disposed upstream of the yarn dividing guide in the yarn running direction, there is more space, making it easier to dispose the focusing guide.

[0016] In the present invention, the focusing guide may be movable between a thread hooking position where the multiple threads can be bundled together in the focusing section, and a retracted position where it does not interfere with the multiple threads.

[0017] By configuring the focusing guide to be movable in this manner, it is no longer necessary to attach and detach the focusing guide each time, making the threading operation even easier.

[0018] In the present invention, the gathering portion may be located within a region where the plurality of regulating portions are aligned in the axial direction of the yarn feeding roller.

[0019] With this configuration, after the multiple yarns upstream of the converging guide in the yarn running direction are captured by the yarn threading aid, less movement is required until they are threaded onto the yarn separating guide, making the threading operation even easier.

[0020] In the present invention, the converging portion may be a V-shaped recess.

[0021] If the converging part is a V-shaped recess, the opening of the converging part becomes wider, making it easier to wrap multiple threads around the converging part. Also, since the converging part becomes narrower towards the back, if multiple threads are wrapped around the converging part, they will naturally be bundled together.

[0022] In the present invention, the V-shaped convergence portion preferably has an opening angle of 10 degrees or more and 100 degrees or less.

[0023] If the opening angle of the V-shape of the bundling portion is too narrow, the yarn is likely to get caught on the edge of the bundling portion and be damaged. Furthermore, if the yarn gets caught on the edge of the bundling portion, it becomes necessary to remove the yarn from the edge, which reduces the efficiency of the threading operation. On the other hand, if the opening angle of the V-shape of the bundling portion is too wide, the yarn is likely to come off the bundling portion. By specifying the opening angle of the V-shape of the bundling portion as described above, the yarn is less likely to get caught on the edge of the bundling portion and is less likely to come off the bundling portion.

[0024] In the present invention, the focusing guide may be formed of a rod-shaped member.

[0025] According to this configuration, the focusing guide can be manufactured using a small amount of material, which is advantageous in terms of cost.

[0026] In the present invention, the rod-shaped member preferably has a circular cross-sectional shape with a diameter of 3 mm or more.

[0027] Such a rod-shaped member has a gently curved surface, so that the thread is less likely to be damaged even if it comes into contact with the thread.

[0028] In the present invention, the multiple regulating portions are open from the base end toward the tip end, and the converging portion is open on the same side as the multiple regulating portions with respect to a reference plane passing through the base ends of the multiple regulating portions.

[0029] When the gathering portion opens on the side opposite the openings of the plurality of regulating portions with respect to a reference plane passing through the base ends of the plurality of regulating portions, the following problem occurs. For example, tension is applied to the yarn hooked on the gathering portion in a direction opposite the openings of the gathering portion. In this state, when the yarn is re-hooked on the regulating portion by the threading aid, it is pulled toward the side opposite the openings of the gathering portion, i.e., toward the openings of the regulating portion. As a result, the yarn comes off the regulating portion. Conversely, if a yarn separating guide is positioned so that the yarn does not come off the regulating portion, the yarn hooked on the gathering portion is pulled toward the side opposite the openings of the regulating portion, i.e., toward the openings of the gathering portion. As a result, the yarn comes off the regulating portion. To prevent the above problems, it is necessary to separately provide a fall-off prevention member on the plurality of regulating portions or the gathering portion to prevent the yarn from falling off. In this regard, in the present invention, the gathering portion opens on the same side as the openings of the plurality of regulating portions with respect to a reference plane passing through the base ends of the plurality of regulating portions. Therefore, in the process of hooking the yarn to the gathering section and then hooking the yarn back to the restricting section, the yarn will not come off the gathering section and the restricting section, and there is no need to provide a separate anti-fall-off member.

[0030] In the present invention, it is preferable that a working space where an operator threads a yarn onto the yarn feed roller is located on one side of the yarn feed roller in the axial direction, and that the focusing guide is arranged so that the focusing portion is located on the one side of a midpoint in the axial direction of the yarn feed roller.

[0031] According to this configuration, since the gathering section is disposed near the work space, an operator in the work space can easily hook the yarn around the gathering section.

[0032] In the present invention, it is preferable that a work space where an operator threads a yarn onto the yarn feed roller is located on one side of the yarn feed roller in a direction intersecting an axial direction thereof, and that a part of the focusing guide extends to an end of the yarn separating guide in the axial direction of the yarn feed roller.

[0033] With this configuration, when operating the focusing guide to hook multiple threads onto the thread separation guide, the operator can easily avoid interference with the multiple threads by operating the part of the focusing guide that extends to the end of the thread separation guide.

[0035] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0036] Fig. 1 is a side view of a spinning take-up device 1 according to this embodiment. As shown in Fig. 1, a plurality of synthetic resin yarns Y spun from a spinning device 2 are oiled by traveling downward while coming into contact with an oil application guide 3 disposed below the yarns. The spinning take-up device 1 has a take-up section 4 that takes up the plurality of oil-applied yarns Y and performs a drawing process on them, and a winding section 5 that winds up the plurality of yarns Y sent from the take-up section 4.

[0037] In the following description, the left side of Fig. 1 is defined as "front," the right side of Fig. 1 as "rear," the front side of the paper in Fig. 1 as "right," and the back side of the paper in Fig. 1 as "left." Note that the yarn take-up device 1 of this embodiment takes up 32 yarns Y spun from the spinning device 2, but in Figs. 1, 2, and 5 to 11, only eight yarns Y are shown to avoid cluttering the drawings. However, in the present invention, the number of yarns Y may be any number. In addition, hereinafter, the upstream side and downstream side in the yarn running direction will simply be referred to as the upstream side and downstream side.

[0038] 2 is a perspective view of the take-up unit 4 after completion of the threading operation. The take-up unit 4 includes, in order from the upstream side, a yarn control guide 11, a yarn feed roller 12, multiple heating rollers 21-25 (five in this embodiment) arranged in an insulating box 20, yarn feed rollers 13 and 14, an intertwining device 16, and a yarn feed roller 15.

[0039] The yarn restriction guide 11 is a comb-like guide formed with a plurality of restriction portions 11a aligned in the left-right direction. When the plurality of yarns Y are inserted into the restriction portions 11a, the movement of the plurality of yarns Y in the left-right direction is restricted.

[0040] The yarn feed roller 12 is a roller around which the multiple yarns Y are wound immediately before being introduced into the thermal insulation box 20, and its rotation axis extends in the front-rear direction. The yarn feed roller 13 is a roller around which the multiple yarns Y are wound immediately after being led out of the thermal insulation box 20, and its rotation axis extends in the front-rear direction. The yarn feed roller 14 is a roller around which the multiple yarns Y are wound immediately before being led into the intertwining device 16, and its rotation axis extends in the left-right direction. The yarn feed roller 15 is a roller around which the multiple yarns Y are wound immediately after being led out of the intertwining device 16, and its rotation axis extends in the left-right direction. As shown by the dashed line in FIG. 1 , the yarn feed roller 15 can move to a yarn threading position near the yarn feed roller 14. The yarn feed rollers 12 to 15 are each drive rollers rotated by a motor (not shown). However, the yarn feed rollers 12 to 15 are not limited to drive rollers and may be driven rollers.

[0041] The entangling device 16 entangles the multiple yarns Y. The entangling device 16 has multiple yarn traveling spaces (not shown), and the multiple yarns Y travel through the respective yarn traveling spaces. Compressed air is injected into the yarn traveling spaces, thereby entangling the yarns Y traveling through the yarn traveling spaces. The entangling device 16 can be disposed at an appropriate position downstream of the heating roller 25 and upstream of the yarn feed roller 15 in the yarn traveling direction.

[0042] Yarn separation guides 32 to 35 (not shown in FIG. 1 ) are fixed immediately upstream of the yarn feed rollers 12 to 15 in the yarn running direction. The yarn separation guides 32 to 35 are comb-like guides formed with a plurality of regulating portions 32a to 35a arranged side by side. The plurality of regulating portions 32a of the yarn separation guide 32 are arranged in the front-to-rear direction in accordance with the axial direction of the yarn feed roller 12. When the plurality of yarns Y are inserted into the regulating portions 32a, the movement of the plurality of yarns Y in the front-to-rear direction is regulated. The plurality of regulating portions 33a of the yarn separation guide 33 are arranged in the front-to-rear direction in accordance with the axial direction of the yarn feed roller 13. When the plurality of yarns Y are inserted into the regulating portions 33a, the movement of the plurality of yarns Y in the front-to-rear direction is regulated. The plurality of regulating portions 34a of the yarn separation guide 34 are arranged in the left-to-right direction in accordance with the axial direction of the yarn feed roller 14. When the plurality of yarns Y are inserted into the regulating portions 34a, the movement of the plurality of yarns Y in the left-to-right direction is regulated. The multiple restricting portions 35a of the yarn separation guide 35 are aligned in the left-right direction in accordance with the axial direction of the yarn feed roller 15. When multiple yarns Y are inserted into the restricting portions 35a, the left-right movement of the multiple yarns Y is restricted. The restricting portions 32a-35a of the yarn separation guides 32-35 are spaced at approximately the same pitch. Hereinafter, for example, the yarn separation guide 32 corresponding to the yarn feed roller 12 may be referred to as the "yarn separation guide 32 of the yarn feed roller 12." Note that it is not essential to place the yarn separation guides 32-35 immediately upstream of each of the yarn feed rollers 12-15. If the axial direction of each of the yarn feed rollers 12-15 is parallel to the axial direction of the immediately preceding roller, the yarn separation guides may be omitted.

[0043] 3, the plurality of restricting portions 32a are open from a base end portion 32a1 toward a tip end portion 32a2. Similarly, the plurality of restricting portions 33a to 35a are open from the base end portion toward the tip end portion. The plurality of restricting portions 33a to 35a are not shown in the figure.

[0044] The heating rollers 21 to 25 are housed in a heat-insulating box 20 made of a heat-insulating material. As shown in FIG. 1, the heat-insulating box 20 is disposed below the oil application guide 3 and above the front end of a bobbin holder 52 of the winding section 5, which will be described later. A door 20a that covers the front end surfaces of the heating rollers 21 to 25 is attached to the heat-insulating box 20 and can be opened and closed freely. As shown in FIG. 2, when the door 20a is open, threading of yarn onto the heating rollers 21 to 25 from the front can be performed. Note that the door 20a is not shown in FIG. 2 and FIGS. 5 to 11.

[0045] The heating rollers 21 to 25 are arranged so that their rotation axes extend in the front-to-rear direction. A slit 20b is formed at the lower end of the right side of the thermal insulation box 20 for introducing the plurality of yarns Y into the thermal insulation box 20. A slit 20c is formed at the upper end of the right side of the thermal insulation box 20 for leading the plurality of yarns Y out of the thermal insulation box 20. The plurality of yarns Y introduced from the slit 20b are wound around the heating rollers 21 to 25 in order from the upstream side and are led out from the slit 20c.

[0046] Each of the heating rollers 21-25 is rotated by a motor (not shown). Each of the heating rollers 21-25 also incorporates a heater (not shown). Of the five heating rollers 21-25, the three upstream heating rollers 21-23 heat the yarns Y before drawing to a temperature equal to or higher than the glass transition temperature of the synthetic resin that is the material of the yarns Y. The rotation speed of the two downstream heating rollers 24, 25 is set faster than the rotation speed of the three upstream heating rollers 21-23. Due to this difference in rotation speed, the yarns Y heated to a temperature equal to or higher than the glass transition temperature are drawn. The two downstream heating rollers 24, 25 are set to a higher temperature than the three upstream heating rollers 21-23, and heat-set the drawn yarns Y.

[0047] As shown in FIG. 1, the winding section 5 is configured to include a machine base 51, two bobbin holders 52, a plurality of traverse guides 53, a contact roller 54, etc. The two bobbin holders 52 extend in the front-to-rear direction, and a plurality of bobbins B are attached to them. The rear ends of the two bobbin holders 52 are supported by a disk-shaped turret 55 rotatably mounted on the machine base 51. The two bobbin holders 52 are each rotated by a motor (not shown). When the bobbin holders 52 rotate, the plurality of bobbins B attached to the bobbin holders 52 also rotate integrally with the bobbin holders 52. Furthermore, the rotation of the turret 55 supporting the two bobbin holders 52 switches the positions of the two bobbin holders 52 between a winding position (upper position in FIG. 1) and a retracted position (lower position in FIG. 1).

[0048] Above the bobbin holder 52, a plurality of traverse guides 53 and a plurality of fulcrum guides 56 are provided corresponding to a plurality of bobbins B. The plurality of yarns Y fed from the yarn feed roller 15 are respectively hooked onto the plurality of fulcrum guides 56. Furthermore, the plurality of yarns Y are traversed in the front-to-back direction around the corresponding fulcrum guides 56 by the plurality of traverse guides 53, and are wound onto the plurality of bobbins B attached to the bobbin holder 52 at the winding position, respectively. In this way, a plurality of packages P are formed on the plurality of bobbins B. The contact roller 54 rotates while contacting the outer peripheral surfaces of the plurality of packages P and applying a predetermined contact pressure. This adjusts the shape of the package P.

[0049] (Focusing Guide) In the yarn separation guide 32, the multiple yarns Y are aligned in the front-to-back direction, whereas in the yarn control guide 11, where the multiple yarns Y are hooked immediately before the yarn separation guide 32, the multiple yarns Y are aligned in the left-to-right direction. In other words, the yarn paths of the multiple yarns Y are twisted approximately 90 degrees immediately before the yarn separation guide 32. Similarly, in the yarn separation guide 34, the multiple yarns Y are aligned in the left-to-right direction, whereas in the yarn feed roller 13, where the multiple yarns Y are hooked immediately before the yarn separation guide 34, the multiple yarns Y are aligned in the front-to-back direction. In other words, the yarn paths of the multiple yarns Y are twisted approximately 90 degrees immediately before the yarn separation guide 34. In the yarn separation guides 32 and 34 where the yarn paths of the multiple yarns Y are twisted immediately before the yarn separation guide 34, threading must be performed using a dedicated threading aid, as described below, making the threading operation difficult. Therefore, in the yarn take-up device 1 of this embodiment, converging guides 42 and 44 are provided on the yarn separation guides 32 and 34 to facilitate the threading operation on the yarn separation guides 32 and 34.

[0050] Fig. 3 is a top view showing the yarn separating guide 32 and the bundling guide 42 of the yarn feed roller 12. Fig. 4 is a top view showing the yarn separating guide 34 and the bundling guide 44 of the yarn feed roller 14. In this embodiment, the bundling guides 42 and 44 have the same configuration, so a description of the bundling guide 44 common to the bundling guide 42 will be omitted. However, the bundling guides 42 and 44 may have different configurations.

[0051] 3, the yarn separating guide 32 of the yarn feeding roller 12 is fixed to a support member 46. The support member 46 is disposed above the yarn feeding roller 12 and is fixed to a frame (not shown) or the like of the yarn take-off device 1. In the yarn separating guide 32, a plurality of regulating portions 32a that are open to the right are arranged in the axial direction (front-rear direction) of the yarn feeding roller 12 at intervals of 4 mm or less. The yarn separating guide 32 is disposed approximately parallel to the axial direction of the yarn feeding roller 12.

[0052] The focusing guide 42 is made by bending a rod-shaped member having a circular cross section with a diameter of 3 mm or more. The focusing guide 42 has a focusing portion 42a, which is a V-shaped recess. The opening angle of the V-shape of the focusing portion 42a is preferably 10 degrees or more and 100 degrees or less, and is set to 60 degrees in this embodiment. However, the opening angle of the V-shape of the focusing portion 42a may be less than 10 degrees or more than 100 degrees.

[0053] The bundling guide 42 is disposed upstream (above in this embodiment) of the yarn separating guide 32. The bundling guide 42 is disposed such that the bundling portion 42a is located within a region where the restricting portions 32a are aligned in the axial direction of the yarn feeding roller 12. The bundling guide 42 is disposed such that the bundling portion 42a is located forward of the midpoint of the yarn feeding roller 12 in the axial direction.

[0054] The bundle guide 42 is pivotably fixed to the upper surface of the support member 46 by a fixing member 47. The bundle guide 42 pivots about the portion fixed to the support member 46, thereby moving between the threading position shown in FIG. 3A and the retracted position shown in FIG. 3B. As shown in FIG. 3A, when the bundle guide 42 is located at the threading position, the bundle portion 42a is located to the right of the yarn separation guide 32. Therefore, if multiple yarns Y are bundled together and threaded on the bundle portion 42a, the multiple yarns Y will not come into contact with the yarn separation guide 32. On the other hand, as shown in FIG. 3B, when the bundle guide 42 is located at the retracted position, the bundle guide 42 is supported by the upper surface of the support member 46 and does not protrude to the right of the yarn separation guide 32. Therefore, the multiple yarns Y do not interfere with the yarn separation guide 32, and the multiple yarns Y can be inserted into the multiple restriction portions 32a formed on the yarn separation guide 32, thereby performing yarn separation.

[0055] As shown in FIG. 3A, the converging portion 42a of the converging guide 42 at the threading position opens on the same side as the openings of the plurality of restricting portions 32a with respect to a reference plane passing through the base ends 32a1 of the plurality of restricting portions 32a. In this embodiment, the reference plane passing through the base ends 32a1 of the plurality of restricting portions 32a is a plane passing through the base ends 32a1 of the plurality of restricting portions 32a and extending from the back side to the front side of the paper in FIG. 3. In other words, the converging portion 42a of the converging guide 42 at the threading position and the plurality of restricting portions 32a both open to the right side with respect to the reference plane.

[0056] As shown in FIG. 4 , the yarn separation guide 34 of the yarn feed roller 14 is fixed to a support member 48. The support member 48 is disposed above the yarn feed roller 14 and is fixed to a frame (not shown) or the like of the yarn take-off device 1. In the yarn separation guide 34, a plurality of forward-open regulating portions 34a are arranged in the axial direction (left-right direction) of the yarn feed roller 14 at intervals of 4 mm or less. The yarn separation guide 34 is disposed slightly tilted with respect to the axial direction of the yarn feed roller 14. The yarn separation guide 34 is tilted with respect to the axial direction of the yarn feed roller 14 in order to minimize bending of the yarn Y between the yarn feed roller 13 and the yarn feed roller 14. However, if bending of the yarn Y does not pose a significant problem, the yarn separation guide 34 may be disposed approximately parallel to the axial direction of the yarn feed roller 12.

[0057] The focusing guide 44 is disposed upstream (above) of the yarn separating guide 34. The focusing guide 44 is disposed such that the focusing portion 44a is located within an area where the plurality of restricting portions 34a are aligned in the axial direction of the yarn feeding roller 14. A portion of the focusing guide 44 extends to the right end of the yarn separating guide 34 in the axial direction of the yarn feeding roller 14.

[0058] The bundle guide 44 is pivotably fixed to the upper surface of the support member 48 by a fixing member 49. The bundle guide 44 pivots about the portion fixed to the support member 48, thereby moving between the threading position shown in FIG. 4A and the retracted position shown in FIG. 4B. As shown in FIG. 4A, when the bundle guide 44 is located at the threading position, the bundle portion 44a is located forward of the yarn separation guide 34. Therefore, if multiple yarns Y are bundled together and threaded on the bundle portion 44a, the multiple yarns Y will not come into contact with the yarn separation guide 34. On the other hand, as shown in FIG. 4B, when the bundle guide 44 is located at the retracted position, the bundle guide 44 is supported by the upper surface of the support member 48 and does not protrude forward of the yarn separation guide 34. Therefore, the multiple yarns Y do not interfere with the yarn separation guide 34, and the multiple yarns Y can be inserted into the multiple restriction portions 34a formed on the yarn separation guide 34, thereby performing yarn separation.

[0059] In this embodiment, bar guides 31, 43, and 45 (see FIG. 5 ) are provided for the yarn restriction guide 11 and the yarn separation guides 33 and 35 instead of focusing guides. Unlike the yarn separation guides 32 and 34, the yarn restriction guide 11 and the yarn separation guides 33 and 35 do not twist the yarn paths of the multiple yarns Y immediately before the guides. Therefore, if multiple yarns Y are threaded on the bar guides 31, 43, and 45, the multiple yarns Y will naturally be aligned at a substantially uniform pitch following the yarn paths on the upstream side, making it easy to thread the yarns on the yarn restriction guide 11 and the yarn separation guides 33 and 35. The bar guides 31, 43, and 45 are configured to be movable between a threading position where the multiple yarns Y are threaded during threading and a retracted position where they do not interfere with the multiple yarns Y.

[0060] 5 to 11, which illustrate the threading operation, focusing guides 42, 44 and bar guides 31, 43, 45 are shown only when they are positioned at the threading positions, and are not shown when they are positioned at the retracted positions. It is preferable that focusing guides 42, 44 and bar guides 31, 43, 45 are configured so that they can be locked at the threading positions and the retracted positions by a locking mechanism (not shown).

[0061] (Threading work) The procedure for threading the yarn feed rollers 12 to 15 and the heating rollers 21 to 25 will be described with reference to Figures 5 to 11. When performing the threading operation, the operator stands in front of the yarn take-off device 1. That is, as shown in Figure 1, a work space 100 in which the operator performs the threading operation is located in front of the yarn take-off device 1, and the operator performs the threading operation from in front of the yarn feed rollers 12 to 15 and the heating rollers 21 to 25.

[0062] At the start of the threading operation, the converging guides 42 and 44 and the bar guides 31, 43, and 45 are moved to the threading positions as shown in Fig. 5. The yarn feed roller 15 is also moved to the threading position near the yarn feed roller 14. First, the operator sucks and holds multiple yarns Y with the suction gun S, and then hooks the multiple yarns Y onto the bar guide 31, which is located at the threading position forward of the yarn regulating guide 11.

[0063] Next, the operator moves the suction gun S to a position where the pitch of the multiple yarns Y on the bar guide 31 is equal to the pitch of the multiple restricting portions 11a of the yarn restricting guide 11. A positioning portion may be provided in advance at such a position. Then, when the bar guide 31 is moved to a retracted position behind the yarn restricting guide 11, the multiple yarns Y are hooked around the multiple restricting portions 11a as shown in FIG. 6.

[0064] Next, the operator handles the suction gun S and threads the yarn in one go around the bundling guide 42, the yarn feed roller 12, the heating rollers 21-25, the bar guide 43, the yarn feed roller 13, the bundling guide 44, the yarn feed roller 14, the bar guide 45, and the yarn feed roller 15 in this order, as shown in Fig. 7, and then places the suction gun S on the floor. At this point, the yarns are not threaded around the yarn separation guides 32-35. Because the multiple yarns Y are bundled together at the bundling portions 42a, 44a of the bundling guides 42, 44, the yarns are also threaded around the yarn feed rollers 12-15 and the heating rollers 21-25 with the multiple yarns Y bundled together.

[0065] Next, threading is performed on the yarn separation guides 32 to 35 in order from the most upstream. As shown in FIG. 8, threading on the yarn separation guide 32 is performed using a threading aid T. The threading aid T is a comb-shaped member with multiple grooves Ta that hold multiple yarns Y. The pitch of the multiple grooves Ta of the threading aid T is approximately the same as the pitch of the restriction portions 32a to 35a of the yarn separation guides 32 to 35.

[0066] As shown in Fig. 8, the operator captures the multiple yarns Y aligned in the left-right direction between the yarn restriction guide 11 and the yarn separation guide 32 with the multiple grooves Ta of the yarn threading auxiliary tool T. Then, as shown in Fig. 9, the operator moves the yarn threading auxiliary tool T so that the multiple grooves Ta of the yarn threading auxiliary tool T are aligned in the front-to-rear direction, thereby twisting the multiple yarns Y by approximately 90 degrees and aligning them in the front-to-rear direction. Then, the operator moves the focusing guide 42 to the retracted position, and then moves the yarn threading auxiliary tool T to hook the multiple yarns Y on the multiple restriction portions 32a of the yarn separation guide 32. In this way, the multiple yarns Y are separated in the yarn separation guide 32.

[0067] As shown in FIG. 7 , the multiple yarns Y that have passed through the yarn regulation guide 11 are bundled into one by the bundling portion of the bundling guide 42. Therefore, the multiple yarns Y before being caught by the yarn threading aid T can maintain a substantially uniform pitch while gradually narrowing as they move from the multiple regulation portions 11a of the yarn regulation guide 11 to the bundling portion 42a of the bundling guide 42. This makes it easier for the yarn threading aid T to catch the multiple yarns Y, thereby reducing the time required for the threading operation. Furthermore, the bundling portion 42a of the bundling guide 42 does not need to have minute dimensions like the multiple regulation portions 32a of the yarn separation guide 32, so the multiple yarns Y can be bundled into one by the bundling portion 42a while minimizing damage to the multiple yarns Y.

[0068] As shown in Fig. 9, when the yarns Y are separated by the yarn separating guide 32, the pitch of the yarns Y at the yarn feed roller 12, heating rollers 21-25, bar guide 43, and yarn feed roller 13, which are downstream of the yarn separating guide 32, follows the pitch of the yarns Y at the yarn separating guide 32. However, at the bundling guide 44, the yarns Y remain bundled together. When the bar guide 43 is moved to the retracted position, the yarns Y that were hooked on the bar guide 43 are hooked on the restricting portions 33a of the yarn separating guide 33, as shown in Fig. 10.

[0069] Next, the operator uses the threading aid T to thread the yarns onto the yarn separation guide 34. As shown in FIG. 10 , the operator captures the multiple yarns Y aligned in the front-to-back direction between the yarn feed roller 13 and the yarn separation guide 34 with the multiple grooves Ta of the threading aid T. Then, as shown in FIG. 11 , the operator moves the threading aid T so that the multiple grooves Ta of the threading aid T are aligned in the left-to-right direction, thereby twisting the multiple yarns Y by approximately 90 degrees and aligning them in the left-to-right direction. Then, the converging guide 44 is moved to the retracted position, and the threading aid T is moved to hook the multiple yarns Y onto the multiple restricting portions 34a of the yarn separation guide 34. In this way, the multiple yarns Y are separated in the yarn separation guide 34. As with threading the yarn separation guide 32, using the converging guide 44 to thread the yarn separation guide 34 also makes it possible to reduce the time required for threading while minimizing damage to the multiple yarns Y.

[0070] As shown in Fig. 11, when the yarns Y are separated by the yarn separating guide 34, the pitches of the yarns Y at the yarn feed roller 14, bar guide 45, and yarn feed roller 15 downstream of the yarn separating guide 34 match the pitches of the yarns Y at the yarn separating guide 34. When the bar guide 45 is moved to the retracted position, the yarns Y that were hooked on the bar guide 45 are hooked on the restricting portions 35a of the yarn separating guide 35, as shown in Fig. 2. The yarn threading operation on the interlacing device 16 is performed using a bar guide (not shown), but a detailed description thereof will be omitted here.

[0071] After completing the yarn threading operation on the yarn feeding rollers 12 to 15 and the heating rollers 21 to 25 in this manner, the operator then performs the yarn threading operation on the winding unit 5. Here, a description of the yarn threading operation on the winding unit 5 will be omitted.

[0072] (effect) In this embodiment, the yarn separation guides 32, 34 are provided with bundling guides 42, 44 formed with bundling portions 42a, 44a that can bundle multiple yarns Y together without the multiple yarns being caught on the multiple restricting portions 32a, 34a. By hooking the multiple yarns Y around the bundling portions 42a, 44a of the bundling guides 42, 44 before hooking them on the yarn separation guides 32, 34, the pitch of the multiple yarns Y can be made approximately uniform upstream of the bundling guides 42, 44, making it easier to work with the threading aid T. Furthermore, since it is not necessary to forcibly hook the multiple yarns Y bundled together around one restricting portion 32a, 34a of the yarn separation guides 32, 34, damage to the yarns Y can be reduced. Therefore, threading can be easily performed while reducing damage to the yarns Y.

[0073] FIG. 12 is a table showing the results of measurements of the time required to thread the yarn separation guides 32 and 34. Diagram (a) of FIG. 12 shows the results for the yarn separation guide 32, and diagram (b) of FIG. 12 shows the results for the yarn separation guide 34. We investigated the extent to which the time required for threading differs for beginners, experienced workers, and skilled workers depending on whether or not the converging guides 42 and 44 are used. When the converging guides 42 and 44 are not used, the multiple yarns Y are first appropriately divided and threaded on the restricting portions 32a and 34a of the yarn separation guides 32 and 34. The measurement results showed that the use of the converging guides 42 and 44 shortened the threading time. A significant improvement was observed, especially for beginners who are unfamiliar with threading. This suggests that the use of the converging guides 42 and 44 makes the threading process easier.

[0074] In this embodiment, the yarn feed roller 13 that feeds the multiple yarns Y is disposed upstream of the yarn separation guide 34, and the direction in which the multiple yarns Y are arranged changes between the yarn feed roller 13 and the yarn separation guide 34. In this case, the direction in which the multiple yarns Y are arranged changes midway from the yarn feed roller 13 to the yarn separation guide 34, which increases the difficulty of working with the threading aid T. However, because the multiple yarns Y can be bundled together by the bundling guide 44 until just before they are threaded on the yarn separation guide 34, working with the threading aid T becomes easier.

[0075] In this embodiment, a yarn restriction guide 11 that restricts the movement of the multiple yarns Y is disposed upstream of the yarn separation guide 32, and the direction in which the multiple yarns Y are arranged changes between the yarn restriction guide 11 and the yarn separation guide 32. In this case, the direction in which the multiple yarns Y are arranged changes midway from the yarn restriction guide 11 to the yarn separation guide 32, which increases the difficulty of work using the threading aid T. However, because the multiple yarns Y can be bundled together by the bundling guide 42 until just before they are threaded on the yarn separation guide 32, work using the threading aid T becomes easier.

[0076] In this embodiment, the focusing guides 42, 44 are arranged upstream of the yarn separating guides 32, 34. The focusing guides 42, 44 may be arranged between the yarn separating guides 32, 34 and the yarn feed rollers 12, 14. However, since the yarn separating guides 32, 34 are arranged near the yarn feed rollers 12, 14, it may be difficult to arrange the focusing guides 42, 44 between the yarn separating guides 32, 34 and the yarn feed rollers 12, 14. In this regard, if the focusing guides 42, 44 are arranged upstream of the yarn separating guides 32, 34, there is more space, making it easier to arrange the focusing guides 42, 44.

[0077] In this embodiment, the focusing guides 42, 44 are movable between a threading position where the bundling sections 42a, 44a can bundle multiple yarns Y into one, and a retracted position where they do not interfere with the multiple yarns Y. By configuring the focusing guides 42, 44 to be movable in this manner, it is no longer necessary to attach and detach the focusing guides 42, 44 each time, making the threading operation even easier.

[0078] In this embodiment, the gathering portions 42a, 44a are located within an area where the plurality of restricting portions 32a, 34a are aligned in the axial direction of the yarn feed rollers 12, 14. With this configuration, after the plurality of yarns Y on the upstream side of the gathering guides 42, 44 are captured by the yarn threading aid T, less movement is required until the yarns Y are threaded on the yarn separating guides 32, 34, making the threading operation even easier.

[0079] In this embodiment, the bundling portions 42a, 44a are V-shaped recesses. If the bundling portions 42a, 44a are V-shaped recesses, the openings of the bundling portions 42a, 44a are wider, making it easier to hook multiple yarns Y around the bundling portions 42a, 44a. In addition, since the openings of the bundling portions 42a, 44a become narrower toward the back, when multiple yarns Y are hooked around the bundling portions 42a, 44a, they are naturally bundled together.

[0080] In this embodiment, the opening angle of the V-shape of the bundling portions 42a, 44a is 10 degrees or more and 100 degrees or less. If the opening angle of the V-shape of the bundling portions 42a, 44a is too narrow, the yarn Y is likely to get caught on the edges of the bundling portions 42a, 44a and be damaged. Furthermore, if the yarn Y gets caught on the edges of the bundling portions 42a, 44a, work must be done to remove the yarn Y from the edges, reducing the efficiency of the threading work. On the other hand, if the opening angle of the V-shape of the bundling portions 42a, 44a is too wide, the yarn Y is likely to come off the bundling portions 42a, 44a. By specifying the opening angle of the V-shape of the bundling portions 42a, 44a as described above, the yarn Y is less likely to get caught on the edges of the bundling portions 42a, 44a and is less likely to come off the bundling portions 42a, 44a.

[0081] In this embodiment, the focus guides 42 and 44 are made of rod-shaped members. With such a configuration, the focus guides 42 and 44 can be manufactured using a small amount of material, which is advantageous in terms of cost.

[0082] In this embodiment, the rod-shaped member has a circular cross section with a diameter of 3 mm or more. Such a rod-shaped member has a gently curved surface, so that it is less likely to be damaged even when the thread Y comes into contact with it.

[0083] In this embodiment, the plurality of restricting portions 32a open from the base end 32a1 toward the tip end 32a2. The gathering portion 42a opens on the same side as the plurality of restricting portions 32a with respect to a reference plane passing through the base ends 32a1 of the plurality of restricting portions 32a. If the gathering portion 42a opens on the opposite side of the reference plane passing through the base ends 32a1 of the plurality of restricting portions 32a from the side on which the plurality of restricting portions 32a open, the following problem occurs. For example, tension is applied to the yarn Y that is threaded on the gathering portion 42a in a direction opposite to the opening of the gathering portion 42a. In this state, the yarn Y that is rethreaded on the restricting portion 32a by the threading aid T is pulled in the direction opposite to the opening of the gathering portion 42a, i.e., toward the opening of the restricting portion 32a. As a result, the yarn Y comes off the restricting portion 32a. Conversely, if the yarn separating guide 32 is positioned so that the yarn Y does not come off the restricting portion 32a, the yarn Y hooked on the collecting portion 42a is pulled toward the side opposite the opening of the restricting portion 32a, i.e., toward the opening of the collecting portion 42a. As a result, the yarn Y comes off the collecting portion 42a. To prevent the above problem, it is necessary to separately provide a drop-off prevention member on each of the restricting portions 32a or the collecting portion 42a to prevent the yarn Y from coming off. In this regard, in the present embodiment, the collecting portion 42a opens on the same side as the opening of the restricting portions 32a with respect to a reference plane passing through the base ends 32a1 of the restricting portions 32a. Therefore, during the process of hooking the yarn Y on the collecting portion 42a and then re-hooking the yarn Y on the restricting portion 32a, the yarn Y does not come off the collecting portion 42a and the restricting portion 32a, and a separate drop-off prevention member is not required.

[0084] In this embodiment, the work space 100 where the operator threads the yarn onto the yarn feed roller 12 is located on one axial side (front side) of the yarn feed roller 12, and the focusing guide 42 is arranged so that the gathering part 42a is located on one side of the midpoint in the axial direction of the yarn feed roller 12. With this configuration, the gathering part 42a is located near the work space 100, making it easy for the operator in the work space 100 to thread the yarn Y onto the gathering part 42a.

[0085] In this embodiment, the work space 100 where the operator threads the yarn onto the yarn feed roller 14 is located on one side (front side) in a direction intersecting the axial direction of the yarn feed roller 14, and a portion of the focusing guide 44 extends to an end of the yarn separation guide 34 in the axial direction of the yarn feed roller 14. With this configuration, when operating the focusing guide 44 to thread multiple yarns Y onto the yarn separation guide 34, the operator can easily avoid interference with the multiple yarns Y by operating the portion of the focusing guide 44 that extends to the end of the yarn separation guide 34.

[0086] (Other embodiments) Modifications of the present invention will now be described.

[0087] In the above embodiment, converging guides 42, 44 are provided for the yarn separating guides 32, 34 immediately before which the multiple yarns Y are twisted, and bar guides 43, 45 are provided for the yarn separating guides 33, 35 immediately before which the multiple yarns Y are not twisted. However, converging guides may be provided instead of the bar guides 43, 45 for the yarn separating guides 33, 35 immediately before which the multiple yarns Y are not twisted.

[0088] In the above embodiment, the converging guides 42, 44 are arranged upstream of the yarn separating guides 32, 34. However, the converging guides 42, 44 may be arranged between the yarn separating guides 32, 34 and the yarn feed rollers 12, 14.

[0089] In the above embodiment, the focusing guides 42, 44 are movable between the threading position and the retracted position by swinging. However, the focusing guides 42, 44 may be moved in a manner other than swinging, for example, by sliding in an appropriate direction. Furthermore, the focusing guides 42, 44 are not limited to being moved manually, but may be moved by a motor, an air cylinder, or the like. Furthermore, instead of configuring the focusing guides 42, 44 to be movable, the focusing guides 42, 44 may be configured to be detachable and can be removed when not needed.

[0090] The specific shapes and arrangements of the focusing guides 42, 44 are not limited to those described in the above embodiment. For example, the focusing guides 42, 44 may be rod-shaped members having an elliptical or polygonal cross-section instead of a circular cross-section. In the case of rod-shaped members having a polygonal cross-section, the edges of the rod-shaped members are preferably chamfered or rounded to prevent damage to the yarn Y. The focusing guides 42, 44 may also be plate-shaped members instead of rod-shaped members. In this case, a notch may be formed in a portion of the plate-shaped member, and the notch may serve as the focusing portion. When a plate-shaped member is used, the edges of the plate-shaped member are preferably chamfered or rounded to prevent damage to the yarn Y. The shapes of the focusing portions 42a, 44a of the focusing guides 42, 44 are not limited to V-shaped recesses. Any shape may be used as long as they can bundle multiple yarns Y together. Specifically, the recesses may be U-shaped, C-shaped, or rectangular.

[0091] In the above embodiment, the converging portion 42a of the converging guide 42 at the threading position opens on the same side as the multiple restricting portions 32a with respect to a reference plane passing through the base ends 32a1 of the multiple restricting portions 32a. However, the converging portion 42a may open on the opposite side of the reference plane passing through the base ends 32a1 of the multiple restricting portions 32a from the side on which the multiple restricting portions 32a open. That is, for example, the converging portion 42a of the converging guide 42 at the threading position may open on the left side of the reference plane, and the multiple restricting portions 32a may open on the right side of the reference plane.

[0092] In the above embodiment, the arrangement direction of the plurality of restricting portions 11a of the yarn restriction guide 11 is perpendicular to the axial direction of the yarn feed roller 12. That is, the angle between the arrangement direction of the plurality of restricting portions 11a and the axial direction of the yarn feed roller 12 is 90 degrees. However, the angle between the arrangement direction of the plurality of restricting portions 11a and the axial direction of the yarn feed roller 12 does not have to be 90 degrees, and may be, for example, 45 degrees, 30 degrees, or 15 degrees. Furthermore, in the above embodiment, the axial direction of the yarn feed roller 13 is perpendicular to the axial direction of the yarn feed roller 14. That is, the angle between the axial direction of the yarn feed roller 13 and the axial direction of the yarn feed roller 14 is 90 degrees. However, the angle between the axial direction of the yarn feed roller 13 and the axial direction of the yarn feed roller 14 does not have to be 90 degrees, and may be, for example, 45 degrees, 30 degrees, or 15 degrees.
