Description

[Technical Field]

[0001] The present invention relates to a yarn winding machine for winding a yarn. [Background technology]

[0002] Patent Document 1 discloses a yarn winding machine (the take-up unit of Patent Document 1) that forms a package by winding multiple yarns spun from a spinning device onto multiple bobbins while traversing the yarns. The yarn winding machine has a bobbin holder to which multiple bobbins are attached along a predetermined arrangement direction, and multiple distribution guides (fulcrum guides of Patent Document 1) that are arranged corresponding to the bobbins and serve as fulcrums when each yarn is traversed.

[0003] Furthermore, the yarn winding machine of Patent Document 1 is provided with a first separator and a second separator as components for threading the yarn onto the multiple bobbins. The multiple yarns threaded onto each distribution guide are temporarily captured by the first separator and then transferred from the first separator to the second separator. The second separator then moves to the vicinity of the multiple bobbins, thereby threading the yarn onto the multiple bobbins.

[0004] Here, when the first separator captures the multiple yarns, the operator generally maintains the multiple yarns sucked and held by a suction gun. The first separator has multiple holding members arranged in the arrangement direction, and the multiple yarns sucked and held by the suction gun are captured by the multiple holding members. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-143435 Summary of the Invention [Problem to be solved by the invention]

[0006] The multiple yarns threaded on the multiple distribution guides converge toward the suction gun, with the pitch of the multiple yarns narrowing as they approach the suction gun (see FIG. 10(b) of Patent Document 1). The first separator captures the multiple yarns held by the suction gun at a position away from the multiple distribution guides, so the pitch of the multiple yarns when captured is narrow. As a result, even if multiple yarns are to be captured by each holding member of the first separator, problems may arise, such as the yarns not being successfully captured by the holding member or multiple yarns being captured by a single holding member. This makes it difficult to smoothly transfer the yarns from the first separator to the second separator. As a result, the efficiency of the bobbin threading operation is reduced.

[0007] An object of the present invention is to accurately and easily wind a plurality of threads wound around a distribution guide onto a plurality of bobbins. [Means for solving the problem]

[0008] The yarn winding machine of the present invention comprises a bobbin holder on which a plurality of bobbins are mounted in a predetermined arrangement direction; a plurality of distribution guides arranged above the bobbin holder in the arrangement direction and corresponding to the plurality of bobbins; a contact roller arranged vertically above the bobbin holder and below the plurality of distribution guides and contacting the outer surfaces of a plurality of packages formed by winding the plurality of yarns onto the plurality of bobbins to apply contact pressure; a yarn capturing member having a plurality of yarn capturing portions arranged in the arrangement direction and capturing the plurality of yarns hooked on the plurality of distribution guides with the plurality of yarn capturing portions; and a thread hooking means having a plurality of yarn holding portions arranged in the arrangement direction and receiving the plurality of yarns captured by the thread capturing member with the plurality of yarn holding portions and hooking them onto the plurality of bobbins, wherein the plurality of yarn capturing portions are configured to capture the plurality of yarns at a position between the distribution guide and the contact roller in the vertical direction, closer to the distribution guide than the contact roller, and are configured to be movable to a transfer position for transferring the captured plurality of yarns to the plurality of yarn holding portions.

[0009] According to the present invention, the multiple yarn catchers can catch multiple yarns arranged at a wide pitch in the arrangement direction at positions close to the distribution guide in the vertical direction. This allows the yarns to be caught accurately and easily by the yarn catcher. In addition, according to the present invention, by moving the multiple yarn catchers to the transfer position, the multiple yarns can be smoothly transferred to the multiple yarn holding units. Therefore, the multiple yarns hooked on the multiple distribution guides can be hooked onto the multiple bobbins accurately and easily.

[0010] In the yarn winding machine of the present invention, it is preferable that the intervals between the plurality of yarn catching units in the arrangement direction are the same as the intervals between the plurality of yarn holding units in the arrangement direction, and the yarn catching member transfers the plurality of yarns to the plurality of yarn holding units while maintaining the intervals between the plurality of yarn catching units that have caught the plurality of yarns constant in the arrangement direction. Note that "the intervals between the plurality of yarn catching units in the arrangement direction and the intervals between the plurality of yarn holding units in the arrangement direction are the same" includes not only the case where the intervals between the two are exactly the same, but also the case where the intervals between the two are approximately the same.

[0011] According to the present invention, there is no need to provide a member for moving the plurality of thread catching units along the arrangement direction, and the device configuration can be simplified.

[0012] In the yarn winding machine of the present invention, it is preferable that the plurality of yarn catching sections are configured to be movable to a retracted position where they are not in contact with the plurality of yarns that are hung on the plurality of distribution guides and wound onto the plurality of bobbins.

[0013] According to the present invention, when the yarn winding machine winds the yarn onto the bobbin, the yarn can be prevented from coming into contact with the yarn catching units by moving the plurality of yarn catching units to the retracted positions.

[0014] In the yarn winding machine of the present invention, it is preferable that the plurality of yarn catching sections are configured to catch the plurality of yarns hooked on the plurality of distribution guides while moving from the retracted position to the transfer position.

[0015] According to the present invention, by moving the plurality of yarn catching sections from the retracted position to the delivery position, the plurality of yarns hooked on the plurality of distribution guides can be smoothly caught.

[0016] In the yarn winding machine of the present invention, it is preferable that the yarn catching member has one or more first swinging members that support the plurality of yarn catching sections and are swingable around an axis along the arrangement direction, and the plurality of yarn catching sections move between the retracted position and the transfer position by swinging the first swinging member.

[0017] According to the present invention, a plurality of thread catching units can be moved with a relatively simple configuration.

[0018] The yarn winding machine of the present invention preferably includes a first movement drive unit that moves the plurality of yarn catching units between the retracted position and the delivery position.

[0019] According to the present invention, the first movement drive unit can move the plurality of yarn catching units, and the plurality of yarns can be caught by each yarn catching unit without the need for an operator, which makes the threading operation even easier.

[0020] In the yarn winding machine of the present invention, it is preferable that the yarn hooking means has a yarn hooking member on which the multiple yarn holding portions are formed, and that, by operating the yarn hooking member, the multiple yarn holding portions, which have received the multiple yarns from the multiple yarn catching portions, are moved to a yarn hooking position, where the multiple yarns are hooked onto the multiple bobbins.

[0021] According to the present invention, the two members, the thread catcher and the thread hooking member, allow multiple threads hooked on the distribution guide to be hooked onto multiple bobbins, thereby preventing an increase in the number of members.

[0022] In the yarn winding machine of the present invention, it is preferable that the first swinging member is configured to be swingable while avoiding contact between the yarn catcher member and the contact roller.

[0023] According to the present invention, there is no need to provide a structure for retracting the contact roller to avoid contact between the thread catcher and the contact roller when moving the multiple thread catchers, and therefore, with a relatively simple structure, damage to the components due to contact between the thread catcher and the contact roller can be prevented.

[0024] In the yarn winding machine of the present invention, it is preferable that each of the plurality of yarn holding sections has a slit that opens to one side in the arrangement direction, the yarn capturing member is configured to be movable in the arrangement direction, and when the plurality of yarn capturing sections are positioned at the transfer position, the yarn capturing member moves from one side to the other side in the arrangement direction, thereby inserting the plurality of yarns captured by the plurality of yarn capturing sections into the slits formed in each of the plurality of yarn holding sections, and when the plurality of yarns are inserted into the plurality of slits, the plurality of yarn capturing sections move from the transfer position to the retracted position, thereby releasing the plurality of yarns from the plurality of yarn capturing sections.

[0025] According to the present invention, the transfer of a plurality of threads from the thread catcher to a plurality of thread holding portions can be performed by moving the thread catcher, and operation control is easy.

[0026] In the yarn winding machine of the present invention, it is preferable that the yarn hooking member has one or more second oscillating members that support the multiple yarn holding units and are oscillating around the arrangement direction as a swing center, and the multiple yarn holding units move between the receiving position and the yarn hooking position by the swing of the second oscillating member.

[0027] According to the present invention, a plurality of suture holding units can be moved with a relatively simple configuration.

[0028] In the yarn winding machine of the present invention, the yarn threading means preferably includes a second movement drive unit that moves the plurality of yarn holding units between the receiving position and the yarn threading position.

[0029] According to the present invention, the second movement drive unit can move each thread holding unit, and multiple threads received by the multiple thread holding units can be hooked onto multiple bobbins without the need for an operator, making the threading operation even easier.

[0031] Next, an embodiment of the present invention will be described. For convenience of explanation, the directions shown in Fig. 1 and Fig. 2 are referred to as the up-down direction, the left-right direction, and the front-rear direction. The up-down direction is the vertical direction in which gravity acts. The left-right direction is a direction perpendicular to the up-down direction. The front-rear direction (arrangement direction of the present invention) is a direction perpendicular to both the up-down direction and the left-right direction, and is the direction in which multiple bobbins B (described later) are arranged side by side. Furthermore, the direction in which a yarn Y (described later) runs is referred to as the yarn running direction.

[0032] (Yarn take-up machine) An outline of the yarn take-off machine 1 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a side view of the yarn take-off machine 1. The front side of the paper in Fig. 1 is the right side.

[0033] The yarn take-off machine 1 is configured to take up multiple (e.g., 16 in this embodiment) yarns Y spun from a spinning device 2, wind them onto multiple bobbins B, and simultaneously form multiple packages P. The spinning device 2 extrudes, for example, a molten polymer that is the material for the yarn Y. The material for the yarn Y is, for example, a polyester-based material such as PET, but is not limited to this. The yarn Y is, for example, a monofilament yarn consisting of a single filament, but is not limited to this.

[0034] As shown in Fig. 1, the yarn take-up machine 1 includes a first godet roller 3, a second godet roller 4, and a yarn winding machine 5. The first godet roller 3 is a roller that sends multiple yarns Y spun from the spinning device 2 downstream in the yarn running direction. The second godet roller 4 is a roller that sends the multiple yarns Y sent downstream in the yarn running direction by the first godet roller 3 to the yarn winding machine 5. The yarn winding machine 5 is a device that winds the multiple yarns Y sent by the second godet roller 4 onto bobbins B to form multiple packages P.

[0035] The first godet roller 3 is a roller whose axial direction is approximately parallel to the left-right direction. The first godet roller 3 is disposed, for example, below the spinning device 2. Multiple yarns Y are wound around the first godet roller 3 in a line in the left-right direction. The first godet roller 3 is driven to rotate by a motor (not shown). As a result, the first godet roller 3 sends the multiple yarns Y downstream in the yarn running direction.

[0036] The second godet roller 4 is a roller whose axial direction is substantially parallel to the left-right direction. The second godet roller 4 is disposed downstream of the first godet roller 3 in the yarn running direction. The second godet roller 4 is disposed above and behind the first godet roller 3. The second godet roller 4 is driven to rotate by a motor (not shown). As a result, the second godet roller 4 sends the yarn Y downstream in the yarn running direction.

[0037] The yarn winding machine 5 is configured to perform a winding operation in which a plurality of yarns Y are wound onto a plurality of bobbins B to form a plurality of packages P. The yarn winding machine 5 is disposed downstream of the second godet roller 4 in the yarn running direction. The yarn winding machine 5 is disposed below the second godet roller 4.

[0038] (yarn winding machine) The configuration of the yarn winding machine 5 will be described with reference to Figs. 1 to 4. Fig. 2 is a front view of the yarn winding machine 5. Fig. 3 is a block diagram showing the electrical configuration of the yarn winding machine 5. Fig. 4(a) is a perspective view showing a yarn catcher 40 (described later). Fig. 4(b) is a side view showing a yarn hooking member 50 (described later).

[0039] As shown in Figures 1 and 2, the yarn winding machine 5 includes a support frame 11, a turret 12, two bobbin holders 13, a machine base 14, a plurality of fulcrum guides 15 (distribution guides of the present invention), a plurality of traverse guides 16, a contact roller 17, a guide support 18, and a control unit 26 (see Figure 3).

[0040] The support frame 11 is a member extending in the front-rear direction. The support frame 11 is cantilevered on an upright machine base 14 and protrudes forward (see FIG. 1). The machine base 14 is a member on which each component of the yarn winding machine 5 is attached or housed. The machine base 14 is disposed, for example, at the rear end of the yarn winding machine 5.

[0041] The turret 12 is a disk-shaped member whose rotation axis direction is approximately parallel to the front-rear direction. The turret 12 is rotatably supported on a machine base 14. The turret 12 is rotationally driven by a turret motor 91 (see FIG. 3).

[0042] Each of the two bobbin holders 13 is rotatably supported by the turret 12 and extends forward from the front surface of the turret 12. The rotation axis direction of each bobbin holder 13 is approximately parallel to the front-rear direction. When viewed from the front-rear direction, the two bobbin holders 13 are arranged symmetrically with respect to the center point of the turret 12 (see FIG. 2). Each bobbin holder 13 has a plurality of bobbins B corresponding to the plurality of yarns Y attached thereto and arranged in the front-rear direction. In this embodiment, each bobbin holder 13 supports, for example, 16 bobbins B. Note that the number of bobbins B that the bobbin holder 13 can support is not limited to this. The plurality of bobbins B are rotatably supported by the bobbin holder 13. Each of the two bobbin holders 13 is individually driven to rotate by a winding motor 92 (see FIG. 3). Each bobbin holder 13 is driven to rotate, for example, counterclockwise when viewed from the front (see the solid arrow in FIG. 2).

[0043] The two bobbin holders 13 are movable between an upper position (the position of the bobbin holder 13 located at the upper side in FIGS. 1 and 2) where the yarn is wound onto each bobbin B, and a lower position (the position of the bobbin holder 13 located at the lower side in FIGS. 1 and 2) below the upper position. As the turret 12 rotates, the bobbin holders 13 move between the upper and lower positions. Multiple yarns Y are simultaneously wound onto multiple bobbins B attached to the bobbin holders 13 located at the upper position.

[0044] The multiple fulcrum guides 15 are guides that serve as fulcrums when the yarn Y is traversed by each traverse guide 16. Each fulcrum guide 15 guides the yarn Y downstream in the yarn running direction. As shown in FIG. 1 , the multiple fulcrum guides 15 are individually provided corresponding to the multiple yarns Y. The multiple fulcrum guides 15 are arranged in the front-rear direction above the bobbin holder 13 that is located at the upper position. The spacing between the multiple fulcrum guides 15 in the front-rear direction is, for example, approximately the same as the spacing between the multiple bobbins B attached to the bobbin holder 13 in the front-rear direction. The spacing between the multiple fulcrum guides 15 in the front-rear direction means the spacing between the centers of the multiple fulcrum guides 15 in the front-rear direction. The spacing between the multiple bobbins B in the front-rear direction means the spacing between the centers of the multiple bobbins B in the front-rear direction.

[0045] The multiple traverse guides 16 are provided individually for the multiple yarns Y. The multiple traverse guides 16 are arranged side by side in the front-to-rear direction. Each traverse guide 16 is driven by, for example, a traverse motor 93 (see FIG. 3 ) and moves back and forth at least in the front-to-rear direction. As a result, the yarn Y hung on the traverse guide 16 is traversed around the fulcrum guide 15.

[0046] As shown in FIGS. 1 and 2, the contact roller 17 is a roller disposed immediately above the bobbin holder 13 positioned at the upper position. Also, as shown in FIGS. 1 and 2, the contact roller 17 is disposed below the plurality of fulcrum guides 15. The axial direction of the contact roller 17 is substantially parallel to the front-to-rear direction. The contact roller 17 contacts the surfaces (outer peripheral surfaces) of the plurality of packages P supported by the bobbin holder 13 positioned at the upper position, thereby applying contact pressure to the surfaces of the plurality of packages P and shaping each package P. The contact roller 17 is configured to be movable between a contact position where it can contact the plurality of bobbins B attached to the bobbin holder 13 positioned at the upper position and a non-contact position above the contact position and not contacting the plurality of bobbins B attached to the bobbin holder 13 positioned at the upper position. When the contact roller 17 is positioned at the non-contact position, yarn is threaded onto each bobbin B.

[0047] The guide support 18 is a member that supports the plurality of fulcrum guides 15. As shown in FIG.

[0048] The control unit 26 has a CPU, a ROM, a RAM, etc. (not shown). As shown in Fig. 3, the control unit 26 is electrically connected to each part of the yarn winding machine 5 (see, for example, the above-mentioned turret motor 91, winding motor 92, traverse motor 93, etc.). The control unit 26 is configured to be able to control the operation of each part of the yarn winding machine 5.

[0049] Furthermore, the yarn winding machine 5 has a yarn catcher 40 and a yarn hooking means 45 as members for threading the plurality of bobbins B (see FIG. 2). The yarn catcher 40 is a member for capturing the plurality of yarns Y hooked on the plurality of fulcrum guides 15. The yarn hooking means 45 is a member for receiving the plurality of yarns Y caught by the yarn catcher 40 and hooking them onto each bobbin B.

[0050] As shown in FIG. 4(a), the thread catching member 40 has a plurality of thread catching portions 41, a plurality of first swinging members 42, and a first swinging shaft 43. The plurality of thread catching portions 41 are arranged in a line in the front-rear direction. The spacing between the plurality of thread catching portions 41 in the front-rear direction is approximately the same as the spacing between the plurality of bobbins B in the front-rear direction. The spacing between the plurality of thread catching portions 41 in the front-rear direction means the spacing between the centers of the plurality of thread catching portions 41 in the front-rear direction. The thread catching portion 41 is, for example, a cylindrical member, and is configured to be able to catch the thread Y by having the thread Y hooked around the cylindrical circumferential surface. However, the thread catching portion 41 is not limited to this shape.

[0051] Each of the multiple first swinging members 42 is a member that supports a corresponding thread catching portion 41. The thread catching portion 41 is connected to the tip end of the first swinging member 42. The first swinging member 42 is, for example, a rod-shaped member that extends in a direction that is approximately perpendicular to the front-rear direction (see FIG. 4(a)). Furthermore, the first swinging member 42 is, for example, bent when viewed from the front-rear direction (see FIG. 2). However, the shape of the first swinging member 42 is not limited to this.

[0052] 2 and 4(a), the first swing shaft 43 extends in the front-rear direction. The first swing shaft 43 swingably supports the plurality of first swing members 42. The first swing shaft 43 is connected to the base ends of the plurality of first swing members 42.

[0053] The first swinging members 42 can be swung together about the first swing shaft 43 by a first movement drive unit 94 (see FIG. 3). The first swinging members 42 can swing together to move the yarn catching units 41 between a retracted position (the position shown in FIGS. 2, 5, 9, and 10), a catching position (the position shown in FIG. 6), and a delivery position (the position shown in FIGS. 7 and 8). The retracted position is a position where each yarn catching unit 41 is not in contact with the yarns Y that are hooked on each fulcrum guide 15 and wound around the bobbins B. The catching position is a position between the retracted position and the delivery position. The catching position is a position between the fulcrum guide 15 and the contact roller 17 in the vertical direction and closer to the fulcrum guide 15 than the contact roller 17. The delivery position is a position where the yarn catching units 41 deliver the yarns Y to the yarn holding units 51 (described later) of the yarn hooking member 50. In this embodiment, the multiple thread catching units 41 located at the retracted position overlap each other when viewed from the front-rear direction. Similarly, the multiple thread catching units 41 located at the catching position overlap each other when viewed from the front-rear direction, and the multiple thread catching units 41 located at the transfer position overlap each other when viewed from the front-rear direction. The first movement drive unit 94 may have, for example, a motor (not shown) as a drive source. Alternatively, the first movement drive unit 94 may have, for example, an air cylinder (not shown) as a drive source. The first movement drive unit 94 is electrically connected to the control unit 26 (see FIG. 3).

[0054] The multiple yarn catching portions 41 are configured to catch the multiple yarns Y hooked on the multiple fulcrum guides 15 while moving from the retracted position to the transfer position (see FIG. 6). In other words, the multiple yarn catching portions 41 are configured to catch the multiple yarns Y hooked on the multiple fulcrum guides 15 at a catch position between the retracted position and the transfer position. In yet another way, the multiple yarn catching portions 41 are configured to catch the multiple yarns Y at a position between the fulcrum guide 15 and the contact roller 17 in the up-down direction and closer to the fulcrum guide 15 than the contact roller 17. Then, the yarn catching member 40 that has caught the multiple yarns Y is configured to transfer the multiple yarns Y to the multiple yarn holding portions 51 of the thread hooking member 50 while maintaining a constant distance between the yarn catching portions 41 in the front-rear direction.

[0055] The multiple first swinging members 42 are configured to be swingable while avoiding contact between the thread catching member 40 and the contact roller 17. In other words, when the thread catching member 40 swings between the retracted position and the transfer position, the multiple thread catching sections 41 and the multiple first swinging members 42 do not come into contact with the contact roller 17.

[0056] Furthermore, the thread catching member 40 is configured to be movable in the front-rear direction by a slide drive unit 95 (see FIG. 3). The thread catching member 40 may be configured to be movable in the front-rear direction when located at the delivery position, and to have its movement in the front-rear direction restricted when located at a position other than the delivery position. The slide drive unit 95 may be configured to be movable in the front-rear direction using, for example, a linear actuator (not shown) as a drive source. The slide drive unit 95 is electrically connected to the control unit 26 (see FIG. 3).

[0057] The threading means 45 receives the multiple threads Y captured by the thread catcher 40 and guides them to a position where they are to be hooked onto the multiple bobbins B. As shown in FIG. 2, the threading means 45 includes a threading member 50 and a second movement drive unit 96 (see FIG. 3). As shown in FIG. 2, the threading member 50 includes multiple thread holding units 51 (see also FIG. 4(b)), a second swinging member 52, and a second swinging shaft 53. As shown in FIG. 4(b), the multiple thread holding units 51 are arranged in a line in the front-rear direction. The spacing between the multiple thread holding units 51 in the front-rear direction is approximately the same as the spacing between the multiple bobbins B in the front-rear direction. The spacing between the multiple thread holding units 51 in the front-rear direction refers to the spacing between the centers of the multiple thread holding units 51 in the front-rear direction. Furthermore, the spacing between the multiple thread holding units 51 in the front-rear direction is approximately the same as the spacing between the multiple thread catchers 41 in the front-rear direction. The thread holding units 51 are generally plate-shaped members. Each of the multiple thread holding portions 51 has a slit 54 that opens to the rear side in the front-to-rear direction (one side in the arrangement direction). The thread holding portion 51 is configured to be able to capture the thread Y by inserting the thread Y into the slit 54. However, the thread holding portion 51 is not limited to this configuration.

[0058] The second swinging member 52 is a member that collectively supports the multiple thread holding parts 51. Each thread holding part 51 is connected to the tip of the second swinging member 52. The second swinging member 52 is, for example, a substantially plate-shaped member that extends in the front-rear direction. The second swinging member 52 is also generally L-shaped when viewed from the front-rear direction (see FIG. 2). However, the shape of the second swinging member 52 is not limited to this.

[0059] The second swing shaft 53 extends in the front-rear direction. The second swing shaft 53 swingably supports the second swing member 52. The second swing shaft 53 is connected to the base end of the second swing member 52.

[0060] The second swinging member 52 can be swung about the second swing shaft 53 by the second movement drive unit 96 (see FIG. 3). The multiple thread holding units 51 are configured to be movable between a standby position (position shown in FIGS. 2 and 9), a receiving position (position shown in FIGS. 6 and 7), and a threading position (position shown in FIG. 10) by the swinging of the second swinging member 52. The standby position is a position where the multiple thread holding units 51 do not overlap with the turret 12 when viewed from the front-rear direction, for example, a position on the left side of the turret 12 when viewed from the front-rear direction (see FIG. 2). When the multiple thread holding units 51 are located at the standby position, the thread Y is wound onto the bobbin B. The receiving position is a position where the multiple thread holding units 51 receive the multiple threads Y from the multiple thread capturing units 41 of the thread capturing member 40. The threading position is a position where the multiple threads Y received from the multiple thread capturing units 41 are threaded onto each bobbin B. In this embodiment, the multiple thread holding units 51 located at the receiving position overlap each other when viewed from the front-to-rear direction. Similarly, the multiple thread holding units 51 located at the threading position overlap each other when viewed from the front-to-rear direction. The second movement drive unit 96 may have, for example, a motor (not shown) as a drive source. Alternatively, the second movement drive unit 96 may have, for example, an air cylinder (not shown) as a drive source. The second movement drive unit 96 is electrically connected to the control unit 26 (see FIG. 3).

[0061] In the yarn winding machine 5 configured as described above, the multiple yarns Y held by the yarn hooking member 50 are hooked onto each bobbin B attached to the bobbin holder 13 located in the upper position from the left side of each bobbin B (see FIG. 10). As described above, each bobbin holder 13 is driven to rotate counterclockwise when viewed from the front (see the solid arrows in FIGS. 2 and 10). Therefore, in the yarn winding machine 5 according to this embodiment, the multiple yarns Y hooked onto each bobbin B from the yarn hooking member 50 are pulled by the bobbin B when they first come into contact with each bobbin B (see FIG. 10).

[0062] (Outline of the procedure for threading the bobbin) Next, an outline of the procedure for hooking the multiple yarns Y hooked on the multiple fulcrum guides 15 onto the bobbin B attached to one of the bobbin holders 13 (assumed to be bobbin holder 13A) will be described below with reference to Figures 5 to 10. Note that a description of the procedure for hooking the yarns onto the multiple fulcrum guides 15 will be omitted.

[0063] In this embodiment, threading onto the bobbin B is performed by an operator operating a suction gun 80 (see FIG. 5, etc.). The suction gun 80 is a component that collectively sucks and holds multiple yarns Y. Threading onto the bobbin B is performed from the space in front of the yarn winding machine 5 (see FIG. 5). During threading onto the bobbin B, the multiple yarns Y that are hooked onto the multiple fulcrum guides 15 converge toward the suction gun 80. In other words, the pitch of the multiple yarns Y in the front-to-rear direction narrows as they approach the suction gun 80.

[0064] First, in the initial state, the bobbin B attached to the bobbin holder 13A and the bobbin B attached to the other bobbin holder 13 (referred to as bobbin holder 13B) have no thread Y wound thereon. Also, in the initial state, the plurality of thread catching units 41 are located in the retracted positions (see FIGS. 2 and 5), and the plurality of thread holding units 51 are located in the standby positions (see FIG. 2). Also, in the initial state, the bobbin holder 13A is located in the lower position, and the bobbin holder 13B is located in the upper position (not shown).

[0065] First, the control unit 26 controls the first movement drive unit 94 to collectively swing the first swinging members 42, thereby moving the plurality of yarn catching units 41 from the retracted position to the catching position (see the solid arrows in FIG. 6). The plurality of yarn catching units 41 catch the plurality of yarns Y hooked on the plurality of fulcrum guides 15 at the catching positions during movement from the retracted position to the delivery position (see FIG. 6). Specifically, the plurality of yarn catching units 41 catch the plurality of yarns Y at the catching positions (positions shown in FIG. 6) that are between the fulcrum guide 15 and the contact roller 17 in the vertical direction and that are closer to the fulcrum guide 15 than the contact roller 17.

[0066] When the multiple yarn catching units 41 reach the catching positions, the control unit 26 controls the turret motor 91 to rotate the turret 12 counterclockwise, thereby moving each bobbin holder 13 to a position where the bobbin holder 13 and the yarn hooking member 50 do not interfere with each other even if the yarn hooking member 50 swings (see the solid arrows in FIG. 6).

[0067] Thereafter, the control unit 26 controls the second movement drive unit 96 to swing the second swinging member 52, thereby moving the plurality of yarn holding units 51 from the standby position to the receiving position (see the solid arrows in FIG. 6). Next, the control unit 26 controls the first movement drive unit 94 to swing the first swinging members 42 together further, thereby moving the plurality of yarn catching units 41 from the catching position to the delivery position (see the solid arrows in FIG. 7). As a result, the plurality of yarns Y caught by the plurality of yarn catching units 41 come into contact with the plurality of yarn holding units 51 of the yarn hooking member 50.

[0068] Next, the control unit 26 controls the slide drive unit 95 to move the thread catcher member 40 from the rear side (one side in the arrangement direction) to the front side (the other side in the arrangement direction) in the front-rear direction (see the solid arrow in FIG. 8). As a result, the threads Y caught by the thread catchers 41 are inserted into the slits 54 (see FIG. 4(b)) formed in the thread holders 51.

[0069] Next, the control unit 26 controls the first movement drive unit 94 to collectively swing all of the first swinging members 42, thereby moving the plurality of yarn catching units 41 from the delivery position to the retracted position (see the solid arrows in FIG. 9). With the plurality of yarns Y inserted into the respective slits 54, the plurality of yarns Y are released from the plurality of yarn catching units 41 by moving from the delivery position to the retracted position. This completes the transfer of the plurality of yarns Y from the yarn catching member 40 to the thread hooking member 50.

[0070] Thereafter, the control unit 26 controls the second movement drive unit 96 to swing the second swinging member 52, and temporarily moves the plurality of thread holding units 51 from the receiving position to the standby position (see the solid arrows in FIG. 9). As a result, the thread hooking member 50 moves to a position where the bobbin holders 13 and the thread hooking member 50 do not interfere with each other even if the bobbin holders 13 move.

[0071] Then, the control unit 26 controls the turret motor 91 to rotate the turret 12 counterclockwise (see the solid arrow in FIG. 10), thereby moving the bobbin holder 13A to the upper position (see the solid arrow in FIG. 10).

[0072] Next, the control unit 26 controls the second movement drive unit 96 to swing the second swinging member 52, thereby moving the plurality of thread holding units 51 from the standby position to the threading position (see the solid arrows in FIG. 10). As a result, the plurality of threads Y held by the plurality of thread holding units 51 approach the bobbins B attached to the bobbin holder 13A positioned in the upper position. Then, the plurality of threads Y adjacent to each bobbin B are hooked onto slits (not shown) formed on the front or rear end of each bobbin B in the front-to-rear direction. This completes threading onto the bobbin B attached to the bobbin holder 13A. Although not shown, after the threading onto the bobbin B attached to the bobbin holder 13A interferes, the contact roller 17 moves down and left to abut against the bobbin B attached to the bobbin holder 13A.

[0073] (effect) The yarn winding machine 5 of this embodiment includes a bobbin holder 13 on which multiple bobbins B are attached along the front-rear direction, multiple fulcrum guides 15 arranged in a line in the front-rear direction above the bobbin holder 13 and corresponding to the multiple bobbins B, a contact roller 17 arranged above the bobbin holder 13 and below the multiple fulcrum guides 15, a yarn catcher 40, and a yarn hooking means 45. The yarn catcher 40 has multiple yarn catch portions 41 arranged in the front-rear direction, and catches the multiple yarns Y hooked on the fulcrum guide 15 with the multiple yarn catch portions 41. The yarn hooking means 45 has multiple yarn holding portions 51 arranged in the front-rear direction, and receives the multiple yarns Y caught by the thread catcher 40 with the multiple yarn holding portions 51 and hooks them onto the respective bobbins B. The multiple yarn catch portions 41 are configured to catch the multiple yarns Y between the fulcrum guide 15 and the contact roller 17 in the up-down direction, and at positions closer to the fulcrum guide 15 than the contact roller 17. Furthermore, the multiple yarn catching units 41 are configured to be movable to a transfer position (see FIGS. 7 and 8) for transferring the captured multiple yarns Y to the multiple yarn holding units 51. Note that the position closer to the fulcrum guide 15 than the contact roller 17 in the vertical direction refers to a position within an area closer to the fulcrum guide 15 than the midpoint between the contact roller 17 and the fulcrum guide 15 in the vertical direction.

[0074] According to this embodiment, the multiple yarn catching parts 41 can catch multiple yarns Y at positions close to the fulcrum guide 15 in the up-down direction and at a wide pitch in the front-to-rear direction. This allows the yarn catching member 40 to catch the yarn Y accurately and easily. In addition, according to this embodiment, by moving the multiple yarn catching parts 41 to the delivery position, the multiple yarns Y can be smoothly delivered to the multiple yarn holding parts 51. Therefore, the multiple yarns Y hooked on the multiple fulcrum guides 15 can be hooked onto the multiple bobbins B accurately and easily.

[0075] Furthermore, in the yarn winding machine 5 of this embodiment, the spacing between the multiple yarn catching sections 41 in the front-to-rear direction is the same as the spacing between the multiple yarn holding sections 51 in the front-to-rear direction, and the yarn catching member 40 transfers the multiple yarns Y to the multiple yarn holding sections 51 while maintaining constant spacing between the multiple yarn catching sections 41 in the front-to-rear direction that have caught the multiple yarns Y. This eliminates the need to provide a member for moving the multiple yarn catching sections 41 along the arrangement direction, and the device configuration can be simplified.

[0076] Furthermore, in the yarn winding machine 5 of this embodiment, the multiple yarn catching units 41 are configured to be movable to retracted positions, which are positions where they do not come into contact with the multiple yarns Y that are hung on the multiple fulcrum guides 15 and wound onto the multiple bobbins B. Accordingly, when the yarn winding machine 5 winds the yarn Y onto the bobbins B, the multiple yarn catching units 41 are moved to the retracted positions, thereby preventing the yarn Y from coming into contact with each of the yarn catching units 41.

[0077] Furthermore, in the yarn winding machine 5 of this embodiment, the plurality of yarn catching sections 41 are configured to catch the plurality of yarns Y hooked on the plurality of fulcrum guides 15 while moving from the retracted position to the delivery position. Thus, by moving the plurality of yarn catching sections 41 from the retracted position to the delivery position, the plurality of yarns Y hooked on the plurality of fulcrum guides 15 can be smoothly caught.

[0078] Furthermore, in the yarn winding machine 5 of this embodiment, the thread catching member 40 has a plurality of first swinging members 42 that support the plurality of thread catching sections 41 and are swingable about an axis (first swinging shaft 43) along the front-rear direction. The plurality of thread catching sections 41 move between the retracted position and the delivery position as a result of the swinging of the first swinging members 42. This allows the plurality of thread catching sections 41 to be moved with a relatively simple configuration.

[0079] Furthermore, the yarn winding machine 5 of this embodiment includes a first movement drive unit 94 that moves the plurality of yarn catching units 41 between the retracted position and the delivery position. This allows the plurality of yarn catching units 41 to be moved by the first movement drive unit 94, and allows the plurality of yarns Y to be caught by each yarn catching unit 41 without the need for an operator. This makes it even easier to perform the threading operation.

[0080] Furthermore, in the yarn winding machine 5 of this embodiment, the threading means 45 has a threading member 50 formed with a plurality of thread holding portions 51. The threading member 50 operates to move the plurality of thread holding portions 51, which have received the plurality of threads Y from the plurality of thread catching portions 41, to threading positions where the plurality of threads Y are hooked onto the plurality of bobbins B. This allows the plurality of threads Y hooked on the fulcrum guide 15 to be hooked onto the plurality of bobbins B by the two members, the thread catching member 40 and the threading member 50, thereby preventing an increase in the number of members.

[0081] Furthermore, in the yarn winding machine 5 of the present embodiment, the first swinging member 42 is configured to be swingable while avoiding contact between the yarn catcher member 40 and the contact roller 17. This eliminates the need to provide a configuration for retracting the contact roller 17 to avoid contact between the yarn catcher member 40 and the contact roller 17 when moving the multiple yarn catchers 41. Therefore, damage to the members due to contact between the yarn catcher member 40 and the contact roller 17 can be prevented with a relatively simple configuration.

[0082] Furthermore, in the yarn winding machine 5 of this embodiment, each of the plurality of yarn holding sections 51 is formed with a slit 54 that opens to the rear side in the front-to-rear direction. The yarn catcher member 40 is configured to be movable in the front-to-rear direction. When the plurality of yarn holding sections 41 are located at the transfer position, the yarn catcher member 40 moves from the rear side to the front side in the front-to-rear direction, causing the plurality of yarns Y captured by the plurality of yarn holding sections 41 to be inserted into the slits 54 formed in each of the plurality of yarn holding sections 51. Then, with the plurality of yarns Y inserted into the plurality of slits 54, the plurality of yarn catchers 41 move from the transfer position to the retracted position, causing the plurality of yarns Y to be released from the plurality of yarn catchers 41. This allows the plurality of yarns Y to be transferred from the yarn catcher member 40 to the plurality of yarn holding sections 51 by moving the yarn catcher member 40, making operation control easy.

[0083] Furthermore, in the yarn winding machine 5 of this embodiment, the thread hooking member 50 has a second swinging member 52 that supports the multiple thread holding units 51 and is swingable around the front-to-rear direction. The multiple thread holding units 51 move between the receiving position and the threading position as a result of the swinging of the second swinging member 52. This allows the multiple thread holding units 51 to be moved with a relatively simple configuration.

[0084] Furthermore, in the yarn winding machine 5 of this embodiment, the threading means 45 has a second movement drive unit 96 that moves the multiple yarn holding units 51 between the receiving position and the threading position. This allows the second movement drive unit 96 to move each of the yarn holding units 51, and allows the multiple yarns Y received by the multiple yarn holding units 51 to be threaded onto the multiple bobbins B without the need for an operator. This makes the threading operation even easier.

[0085] Furthermore, the yarn winding machine 5 of this embodiment includes two bobbin holders 13 that are parallel to each other and are movable between an upper position, where the yarn Y is wound onto each bobbin B, and a lower position that is lower than the upper position. In a configuration in which the two bobbin holders 13 are in an upper position and a lower position, if a component such as a yarn converging guide is provided as in a conventional configuration (e.g., Patent Document 1), the yarn winding machine 5 would have a more complicated device configuration. The yarn winding machine 5 of this embodiment, which does not require a component such as a yarn converging guide, is configured in such a way that the two bobbin holders 13 are movable between the upper position and the lower position, and can more effectively simplify the device configuration while facilitating yarn threading.

[0086] (Variation) The following describes modifications of the above embodiment, but the same reference numerals are used to designate components having the same configuration as the above embodiment, and the description thereof will be omitted as appropriate.

[0087] In the above embodiment, the spacing between the multiple thread holding portions 51 in the front-rear direction is approximately the same as the spacing between the multiple thread catching portions 41 in the front-rear direction. However, the spacing between the multiple thread holding portions 51 in the front-rear direction may be different from the spacing between the multiple thread catching portions 41 in the front-rear direction. In this case, after the thread catching member 40 has the multiple thread catching portions 41 catch the multiple threads Y, it changes the spacing between the multiple thread catching portions 41 in the front-rear direction to be approximately the same as the spacing between the multiple thread holding portions 51 in the front-rear direction. Thereafter, the thread catching member 40 transfers the multiple threads Y from the multiple thread catching portions 41 to the multiple thread holding portions 51.

[0088] In the above embodiment, the spacing between the multiple thread holding units 51 in the front-rear direction is approximately the same as the spacing between the bobbins B in the front-rear direction. However, the spacing between the multiple thread holding units 51 in the front-rear direction may be different from the spacing between the bobbins B in the front-rear direction. In this case, the spacing between the thread holding units 51 in the front-rear direction is configured to be changeable. After receiving the multiple threads Y from the thread catcher 40, the thread hooking member 50 adjusts the spacing between the thread holding units 51 in the front-rear direction to the same spacing between the bobbins B in the front-rear direction, and then threads the threads onto each bobbin B.

[0089] In the above embodiment, the thread catcher 40 has a plurality of first swinging members 42 that respectively support a plurality of thread catchers 41. However, the thread catcher 40 may have a single first swinging member 42 that collectively supports a plurality of thread catchers 41. Also, in the above embodiment, the thread hooking member 50 has a single second swinging member 52 that collectively supports a plurality of thread holding portions 51. However, the thread hooking member 50 may have a plurality of second swinging members 52 that respectively support a plurality of thread holding portions 51.

[0090] In the above embodiment, the thread catching member 40 is configured to move between the retracted position and the delivery position by the swinging of the first swinging member 42. However, the configuration for moving the thread catching member 40 is not limited to this. For example, the thread catching member 40 may be configured to move between the retracted position and the delivery position by moving linearly along a rail extending in a predetermined direction.

[0091] In the above embodiment, the threading member 50 is configured to move between the standby position, the receiving position, and the threading position by swinging the second swinging member 52. However, the configuration for moving the threading member 50 is not limited to this. For example, the threading member 50 may be configured to move between the standby position, the receiving position, and the threading position by moving linearly along a rail extending in a predetermined direction.

[0092] In the above embodiment, a first movement drive unit 94 is provided to move the thread catcher member 40 between the retracted position and the delivery position. However, the thread catcher member 40 may be configured to be manually movable between the retracted position and the delivery position. Also, in the above embodiment, a second movement drive unit 96 is provided to move the thread hooking member 50 between the receiving position and the threading position. However, the thread hooking member 50 may be configured to be manually movable between the receiving position and the threading position.

[0093] In the above embodiment, the thread hooking member 50 is configured to be movable between a standby position, a receiving position, and a threading position. However, the thread hooking member 50 may be configured not to be able to take the standby position. Alternatively, the thread hooking member 50 may be configured to be fixedly disposed at the threading position. In this case, the transfer position of the thread catcher member 40 is a position where multiple threads Y can be transferred to the thread hooking member 50 located at the threading position.

[0094] The yarn winding machine 5 in the above embodiment has two bobbin holders 13. However, the yarn winding machine 5 may have a configuration including one bobbin holder 13.

[0095] In the above embodiment, each thread holding portion 51 is formed with a slit 54 that opens to the rear side in the front-to-rear direction. However, the slit 54 may also open to the front side in the front-to-rear direction. In this case, the thread catcher member 40 located at the delivery position moves from the front side to the rear side in the front-to-rear direction, and thereby the multiple threads Y caught by the multiple thread catchers 41 are inserted into the slits 54 formed in each of the multiple thread holding portions 51. Also, the slits 54 do not have to be formed in each thread holding portion 51. In this case, each thread holding portion 51 has a portion capable of holding the thread Y.

[0096] In the above embodiment, the thread catcher 40, which has been moved from the retracted position to the catcher position in order to catch the multiple threads Y hooked on the fulcrum guide 15, may or may not stop at the catcher position. If the thread catcher 40 does not stop at the catcher position, the control unit 26 moves the thread hooking member 50 to the receiving position before the thread catcher member 40 reaches the delivery position. Also, the thread hooking member 50 may move to the receiving position before the thread catcher member 40 starts moving from the retracted position toward the delivery position.

[0097] In the above embodiment, the threading means 45 has a threading member 50 that hooks multiple threads Y onto each bobbin B attached to the bobbin holder 13 (bobbin holder 13A) located in the upper position from the left side of each bobbin B (see FIG. 10). However, the threading means is not limited to this. For example, as shown in FIG. 11, the threading means 145 may have a threading member 60 that hooks multiple threads Y onto each bobbin B attached to the bobbin holder 13 (bobbin holder 13A) located in the upper position from the right side of each bobbin B. The threading member 60 has multiple thread holding portions (not shown) arranged in the front-to-rear direction. The threading member 60 is configured to receive the multiple threads Y captured by the thread catcher member 40 with the thread holding portions. The threading member 60 is movable to a threading position where the multiple threads Y received by the multiple thread holding portions are hooked onto the multiple bobbins B. The threading position of the threading member 60 is, for example, a position to the right and below the bobbin B.

[0098] The threading means may also include a threading member (for example, the threading member 60 described above; hereinafter referred to as the right threading member) located on the right side of the bobbin holder 13 located in the upper position, and a threading member (for example, the threading member 50 of the above embodiment; hereinafter referred to as the left threading member) located on the left side of the bobbin holder 13 located in the upper position. In this case, the right threading member and the left threading member are configured to allow multiple threads Y to be handed over from the right threading member to the left threading member. The multiple threads Y caught by the thread catcher member 40 are first handed over to the right threading member. Next, the multiple threads Y handed over to the right threading member are further handed over to the left threading member. The multiple threads Y handed over to the left threading member are then hooked onto each bobbin B from the left side of each bobbin B.

[0099] The multiple distribution guides of the present invention are not limited to the multiple fulcrum guides 15. For example, the multiple distribution guides may be guides arranged upstream of the multiple fulcrum guides 15 in the yarn running direction. The spacing between the multiple distribution guides in the front-to-rear direction is, for example, approximately the same as the spacing between the multiple fulcrum guides 15 in the front-to-rear direction.

[0100] In the above embodiment, an operator operates the suction gun 80 to thread the bobbin B. However, the robot arm may operate the suction gun 80 attached to the tip of the arm to thread the bobbin B.

[0101] The present invention is not limited to the yarn take-up machine 1, but can be applied to various yarn winding machines configured to wind a plurality of yarns Y. [Explanation of symbols]
