Description

Technical Field

[0001] This invention relates to a thread processing apparatus for performing a prescribed treatment on thread. Background Technology

[0002] Previously, spinning production equipment was known to be configured to take multiple filaments spun from a spinning device by a take-up device. For example, Patent Document 1 discloses a spinning production equipment (spinning take-up device of Patent Document 1), which includes a spinning device that spins multiple filaments downward and a filament conveying roller disposed below the spinning device for conveying the multiple filaments.

[0003] In such spinning production equipment, a yarn processing device, including a migration nozzle and other yarn processing parts, is sometimes provided in the yarn channel between the spinning unit and the yarn conveying roller. The migration nozzle is a device that applies a bundled effect to the yarn using the jetting action of compressed air. For example, the migration nozzle has the same configuration as the winding section of the winding device described in Patent Document 2, and applies a bundled effect to multiple yarns that travel in approximately parallel and at approximately equal intervals. Upstream and downstream of the migration nozzle in the yarn travel direction, limiting guides are provided to restrict the multiple yarns so that they become approximately parallel and at approximately equal intervals within the migration nozzle. Multiple slots are formed on each limiting guide at intervals equal to the spacing between the multiple yarns in the migration nozzle. By hooking the multiple yarns into the multiple slots formed on each limiting guide, the multiple yarns can travel in approximately parallel and at approximately equal intervals within the migration nozzle.

[0007] Patent Document 2: Japanese Patent Application Publication No. 2019-105007

[0008] Here, when hooking multiple yarns spun from the spinning device onto two limiting guides located upstream and downstream of the migration nozzle, a suction gun is used to concentrate and attract the multiple yarns. The multiple yarns spun from the spinning device converge at the suction port of the suction gun, and the spacing between the multiple yarns narrows as they move from the upstream side to the downstream side in the yarn travel direction. Therefore, the yarns are hooked onto the two limiting guides by an operator while adjusting the position of the suction gun to match the spacing of the slots in each limiting guide. However, when hooking the yarns onto the two limiting guides of the yarn handling device using the suction gun, the following problem arises.

[0009] As described above, the spacing of the multiple threads attracted by the suction gun differs on the upstream and downstream sides of the thread travel direction. Furthermore, two separate guide wire restrictors in the thread travel direction have multiple slots formed at equal intervals. Therefore, even if the suction gun is positioned to match the slot spacing of one guide wire restrictor with the spacing of the multiple threads, the slot spacing of the other guide wire restrictor will still not match the spacing of the multiple threads, resulting in accidental hooking of threads into slots of the other guide wire restrictor that should not be hooked. Consequently, when using the suction gun to hook threads onto the two guide wire restrictors, the operator needs to hook each thread one by one into the multiple slots of each guide wire restrictor, resulting in a significant time commitment.

[0010] Furthermore, the aforementioned problems arise not only in thread processing devices that have migration nozzles as thread processing sections, but also in thread processing devices where the same limiting guide is installed. Specifically, in order to perform prescribed processing on multiple threads that are approximately parallel and travel at approximately equal intervals through the thread processing section, the same problem arises in other devices (e.g., oil nozzles for applying oil to multiple threads, tension sensors for detecting the tension of multiple threads, etc.) that provide limiting guides upstream and downstream of the thread processing section. Summary of the Invention

[0011] The purpose of this invention is to facilitate the wire-hanging operation of two limiting guides arranged on the upstream and downstream sides of the wire processing section of the wire processing device in the wire travel direction.

[0012] The thread processing apparatus of the present invention is characterized by comprising: a thread processing unit for performing prescribed processing on a plurality of threads, wherein the plurality of threads are arranged in an arrangement direction intersecting the thread travel direction of the plurality of threads; a first thread guide having a plurality of first grooves arranged in the arrangement direction and disposed upstream of the thread processing unit in the thread travel direction; a second thread guide having a plurality of second grooves with a spacing in the arrangement direction equal to that of the plurality of first grooves and disposed downstream of the thread processing unit in the thread travel direction; a first thread holding member having a plurality of first holding grooves with a spacing in the arrangement direction equal to that of the plurality of first grooves, capable of holding the plurality of threads hooked to the first thread guide; and a second thread holding member having a plurality of second holding grooves with a spacing in the arrangement direction equal to that of the plurality of second grooves, capable of holding the threads hooked to the first thread guide. The first wire holding member of the second wire guide described above is movable between the wire hanging position where the multiple wires are hooked into the multiple first holding grooves and the handover completion position where the multiple wires have completed their handover to the first wire guide. The second wire holding member is also movable between the wire hanging position where the multiple wires are hooked into the multiple second holding grooves and the handover completion position where the multiple wires have completed their handover to the second wire guide. The first wire holding member in the wire hanging position and the second wire holding member in the wire hanging position are adjacent to each other in the wire travel direction. When viewed from the arrangement direction, the angle formed by the depth direction of the first holding groove of the first wire holding member in the wire hanging position (i.e., the first depth direction) and the depth direction of the second holding groove of the second wire holding member in the wire hanging position (i.e., the second depth direction) is an acute angle.

[0013] In this invention, when attaching threads to the first and second thread-holding guides, multiple threads are temporarily held by the first and second thread-holding members, which are in the thread-attaching position. Since the first and second thread-holding members are adjacent to each other in the thread-traveling direction, it is easy to hook multiple threads together. Then, by moving the first and second thread-holding members holding the multiple threads to the handover completion position, multiple threads can be hooked to the first and second thread-holding guides. Therefore, even when the thread processing device is positioned in a region where the spacing between the multiple threads narrows from the upstream side to the downstream side in the thread-traveling direction, the thread-attaching operation to the first thread-holding guide located upstream of the thread processing unit and the second thread-holding guide located downstream in the thread-traveling direction can be easily performed.

[0014] However, when hooking multiple threads onto a thread holding component as described above, it is ideal for the operator to observe the thread holding component while peering into the bottom of its holding grooves—that is, to observe the thread holding component from the depth direction of each holding groove—while performing the thread hooking operation. This is based on the following reasoning: the spacing between the multiple threads narrows as they approach the suction port of the suction gun; in other words, the spacing varies depending on the position of the thread's travel direction. Therefore, at the same position in the thread's travel direction, if the spacing of the multiple threads is not matched with the spacing of the holding grooves of each thread holding component, the spacing may deviate, and thread hooking may fail. Therefore, when it is necessary to accurately match the spacing of the threads with the spacing of the holding grooves at the same position in the thread's travel direction, it is preferable for the operator to observe the thread holding component while peering into the bottom of the holding grooves while hooking the threads. However, when the operator observes each thread holding component by peering into the bottom of the holding grooves, the visual visibility of the multiple holding grooves formed on the thread holding component becomes poor. Specifically, when operators observe the wire holding components, the portion holding the bottom of the groove and the portion not forming a groove are arranged in roughly the same straight line, making it difficult to distinguish between the grooved and non-grooved portions. As a result, there are problems with the wire holding time of each wire holding component, and consequently, the wire holding time of the two limiting wire guides.

[0015] According to the present invention, when viewed from the arrangement direction, the angle formed by the depth direction (i.e., the first depth direction) of the first retaining groove of the first thread holding member in the thread hanging position and the depth direction (i.e., the second depth direction) of the second retaining groove of the second thread holding member in the thread hanging position is an acute angle. Therefore, even if the operator observes by peering into the bottom of the retaining groove of either thread holding member in the thread hanging position in order to match the spacing of the multiple threads concentratedly attracted by the suction gun with the spacing of the retaining grooves, the thread holding member in the other thread hanging position is observed from a direction intersecting the depth direction of the retaining groove. That is, when the operator observes the two thread holding members in the thread hanging position, the portion of the other thread holding member that becomes the bottom of the retaining groove and the portion that does not become the groove are not arranged in a substantially straight line, and the portion that becomes the groove and the portion that does not become the groove are easily distinguishable. In this invention, the two thread holding members in the thread hanging position are adjacent to each other in the thread travel direction. Therefore, the operator uses the spacing between the holding grooves of the other thread holding member, which is easily identifiable as a groove portion, as a reference to hook multiple threads into each holding groove of the two thread holding members, thereby facilitating the thread hanging operation to the two thread holding members. This also facilitates the thread hanging operation to the two limiting guides located upstream and downstream of the thread processing section of the thread processing device in the thread travel direction.

[0016] In the thread processing apparatus of the present invention, preferably, in the first depth direction, the front end of the second thread holding member in the thread hanging position is closer to the opening side of the first holding groove than the front end of the first thread holding member in the thread hanging position; or, in the second depth direction, the front end of the first thread holding member in the thread hanging position is closer to the opening side of the second holding groove than the front end of the second thread holding member in the thread hanging position.

[0017] When performing wire-hanging operations, the operator's line of sight becomes difficult to determine when both wire-hanging components are in view. That is, even if the operator focuses on one wire-hanging component, the other will inevitably come into view, causing the line of sight to easily drift away. This makes wire-hanging operations difficult. According to the present invention, the operator can partially or completely conceal the other wire-hanging component behind the first one, thus allowing observation of both wire-hanging components in the wire-hanging position. Therefore, even when focusing on one wire-hanging component, the operator can partially or completely remove the other from view, suppressing line-of-sight deviation. This makes wire-hanging operations easier.

[0018] In the thread processing apparatus of the present invention, it is preferable that, when viewed from the above-mentioned arrangement direction, the angle between the first depth direction and the second depth direction is 15 degrees or more.

[0019] When the angle between the first depth direction and the second depth direction when viewed from the arrangement direction is too small, there is a limit to the improvement of the visual recognizability of the spacing between the holding grooves of each thread holding member in the thread-hanging position. According to the present invention, the angle between the first depth direction and the second depth direction when viewed from the arrangement direction is 15 degrees or more. Therefore, when observing by peeking at the bottom of the holding groove of the thread holding member in the thread-hanging position, it is possible to clearly distinguish the bottom part of the holding groove of the thread holding member in the other thread-hanging position from the part that is not a groove. As a result, the thread-hanging operation to the two thread holding members becomes easier.

[0020] In the thread processing apparatus of the present invention, it is preferable that the first thread holding member and the second thread holding member are plate-shaped members.

[0021] According to the present invention, by reducing the thickness of the first and second thread holding members, which are composed of plate-like components, the first and second thread holding members, when in the thread-hanging position, can be brought closer together in the thread-tracing direction. Therefore, it is easier to perform the operation of concentrating multiple threads in the multiple holding slots of each thread holding member.

[0022] Preferably, the thread processing apparatus of the present invention includes a linkage mechanism that links the movement of the first thread holding member between the thread hanging position and the handover completion position with the movement of the second thread holding member between the thread hanging position and the handover completion position.

[0023] When only the wire transfer from one wire holding member to the wire guide is performed initially, and this is followed by a subsequent wire transfer from the other wire holding member to the wire guide, the wire may float up and detach from the wire guide on the side where the wire transfer has already been completed. According to the present invention, the wire transfer from the first wire holding member to the first wire guide and the wire transfer from the second wire holding member to the second wire guide can be performed at the same timing. Therefore, the wire loading operation to both wire guides can be performed more reliably.

[0024] Preferably, in the thread processing apparatus of the present invention, the linkage mechanism includes: a first swing arm, which is rotatable about a first swing axis along the arrangement direction, and supports the first thread holding member to swing; and a second swing arm, which is rotatable about a second swing axis along the arrangement direction, and supports the second thread holding member to swing. The first swing arm includes a first gear, and the second swing arm includes a second gear. The linkage mechanism causes the first swing arm and the second swing arm to rotate in conjunction through the meshing of the first gear and the second gear, thereby linking the movement of the first thread holding member with the movement of the second thread holding member.

[0025] According to the present invention, the first swing arm and the second swing arm rotate in conjunction with each other through the meshing of the first gear and the second gear, thereby enabling the first wire holding member and the second wire holding member to swing in conjunction. Therefore, complex configuration and control are not required to enable the first wire holding member and the second wire holding member to move in conjunction.

[0026] In the thread processing apparatus of the present invention, preferably, the thread holding position of the first thread holding member is such that, when viewed from the arrangement direction, the first thread holding member deviates from the thread channel where multiple threads are hooked on the first and second thread limiting guides, toward the opening direction of the first groove; and the thread holding position of the second thread holding member is such that, when viewed from the arrangement direction, the second thread holding member deviates from the thread channel where multiple threads are hooked on the first and second thread limiting guides, toward the opening direction of the second groove.

[0027] According to the present invention, when multiple threads are hooked onto the first thread holding member and the second thread holding member in the thread-hanging position, accidental hooking of threads into the slots of the first limiting thread guide and the second limiting thread guide that should not normally be hooked onto threads can be prevented. Then, by moving the first thread holding member to the handover completion position while the first thread holding member holds threads and the first limiting thread guide is not hooked onto threads, threads can be hooked onto the first slots of the multiple first slots more reliably. Similarly, by moving the second thread holding member to the handover completion position while the second limiting thread guide is not hooked onto threads, threads can be hooked onto the second slots of the multiple second slots more reliably.

[0028] In the thread processing apparatus of the present invention, the first limiting guide is preferably positioned such that, when viewed from the arrangement direction, it deviates from the thread channel of the plurality of threads hooked on the first thread holding member at the thread hanging position.

[0029] According to the present invention, when hooking the wire into the first wire holding member in the wire holding position, it is possible to further suppress the accidental hooking of the wire into the first slot of the plurality of first slots of the first limiting wire guide, which should not normally hook the wire.

[0063] (Overall composition of spinning production equipment 1)

[0064] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a diagram showing the general structure of spinning production equipment 1. The following will... Figure 1 Set the top-to-bottom direction of the paper as the top-to-bottom direction, and the left-to-right direction of the paper as the left-to-right direction. Additionally, set... Figure 1 The direction perpendicular to the paper is defined as the front-back direction, and the side of the paper closest to the front is defined as the front. The above directional terms will be used appropriately in the following explanations.

[0065] The spinning production equipment 1 is configured such that a winding device 4 winds up multiple filaments Y spun from a spinning device 2. The spinning device 2 is a device that spins molten polymer downwards as filaments Y. Figure 1 As shown, the spinning production equipment 1 includes multiple oiling guides 5 each equipped with an oiling nozzle, multiple guiding guides 6, a yarn handling device 7, two guide rollers 11 and 12, a spinning stretching device 3, and a winding device 4. The spinning device 2 and the multiple oiling guides 5 and multiple guiding guides 6 disposed below it are arranged in the upper layer (layer 2). The yarn handling device 7, the two guide rollers 11 and 12, the spinning stretching device 3, and the winding device 4 are arranged in the lower layer (layer 1).

[0066] Multiple oiling guides 5 are arranged below the spinning device 2 to apply oil to the multiple filaments Y spun downwards from the spinning device 2. Multiple guiding guides 6 are arranged at equal intervals in the left-right direction below each of the multiple oiling guides 5, and individually guide the multiple filaments Y that have been applied with oil.

[0067] The thread processing device 7 is disposed below a plurality of thread guides 6 and is a device for applying bundled properties to multiple threads Y individually guided by the plurality of thread guides 6 using the jet action of compressed air. The thread processing device 7 has a first limiting thread guide 22 and a second limiting thread guide 23 (see reference). Figure 2 Multiple threads Y, hooked to the first limiting guide 22 and the second limiting guide 23, are generally parallel to each other and travel at approximately equal intervals in the left-right direction. Details of the thread handling device 7 will be described later.

[0068] like Figure 1As shown, guide rollers 11 and 12 are positioned downstream of the yarn travel direction in the yarn handling device 7 and are driven to rotate by a motor (not shown). Multiple yarns Y spun from the spinning device 2 are wound onto guide roller 11 via oil guide 5, guide guide 6, and yarn handling device 7, and then conveyed to the spinning stretching device 3 by guide roller 11. Multiple yarns Y, heated and stretched by the spinning stretching device 3, are wound onto guide roller 12 and conveyed to the take-up device 4 by guide roller 12. In reality, a winding device and other guide rollers are positioned downstream of guide roller 12 and upstream of take-up device 4 in the yarn travel direction, but... Figure 1 The text is omitted.

[0069] The spinning and stretching apparatus 3 is a device for heating and stretching multiple filaments Y, and is located below the spinning apparatus 2. The spinning and stretching apparatus 3 includes a heat preservation box 60 and five guide rollers 91-95 housed inside the heat preservation box 60. A filament inlet 60a is formed on the lower part of the right side of the heat preservation box 60 for guiding the multiple filaments Y into the heat preservation box 60, and a filament outlet 60b is formed on the upper part of the right side of the heat preservation box 60 for guiding the multiple filaments Y out of the heat preservation box 60.

[0070] The three lower guide rollers 91-93 are preheating rollers used to preheat the multiple yarns Y before stretching, while the two upper guide rollers 94 and 95 are heat-setting rollers used to heat-set the stretched yarns Y. The surface temperature of the two upper guide rollers 94 and 95 is set to a higher temperature than that of the three lower guide rollers 91-93. Furthermore, the yarn feeding speed of the two upper guide rollers 94 and 95 is faster than that of the three lower guide rollers 91-93.

[0071] Multiple threads Y, introduced into the insulation box 60 via thread inlet 60a, are first preheated to a stretchable temperature during conveying by guide rollers 91-93. The preheated threads Y are then stretched by the difference in thread conveying speed between guide rollers 93 and 94. Furthermore, the threads Y are further heated to a high temperature during conveying by guide rollers 94 and 95, and their stretched state is heat-set. The stretched threads Y are then discharged from the insulation box 60 via thread outlet 60b.

[0072] The winding device 4 is a device for winding multiple filaments Y and is located below the spinning and stretching device 3. The winding device 4 includes a bobbin support 13, a contact roller 14, etc. The bobbin support 13 has a cylindrical shape extending in the front-to-back direction and is driven to rotate by a motor (not shown). Multiple bobbins B are mounted on the bobbin support 13 in an axially aligned manner. The winding device 4 rotates the bobbin support 13, thereby simultaneously winding multiple filaments Y onto the multiple bobbins B to produce multiple packages P. The contact roller 14 contacts the surfaces of the multiple packages P and applies a predetermined contact pressure to adjust the shape of the packages P.

[0073] (Thread processing device 7)

[0074] Next, refer to Figures 2-8 The thread processing device 7 will be described in detail. Furthermore, in Figure 2 as well as Figure 3 For illustrative purposes, the description of a portion of the multiple threads Y is omitted. Additionally, in... Figure 7 as well as Figure 8 For illustrative purposes, the description of thread Y is omitted. The thread processing apparatus 7 includes a substrate 20, a thread processing section 21, a first thread guide 22, a second thread guide 23, a first thread holding member 24, a second thread holding member 25, and a linkage mechanism 30 (see reference). Figure 7 The thread handling device 7 is positioned, for example, in the vertical direction, slightly above the eye level of the worker who is hooking the thread Y onto the thread handling device 7. For example, a position slightly above the worker's eye level means approximately 2 meters above the ground level below.

[0075] The substrate 20 is a component with a generally rectangular parallelepiped shape. The thread processing section 21 is used to process the threads along the arrangement direction ( Figure 2 Multiple threads Y arranged in a left-right direction are subjected to prescribed processing. Specifically, the thread processing unit 21 is a device that uses the jetting action of compressed air to apply a bundled effect to the multiple threads Y. Figure 3 as well as Figure 4 As shown, the wire processing section 21 is formed by arranging a plurality of interlacing sheets 26 in the left-right direction on the front surface of the substrate 20 in the front-back direction. Furthermore, in Figure 2 The description of intercourse piece 26 is omitted. Additionally, as... Figure 1 As shown, the yarn processing unit 21 is positioned below the plurality of yarn guides 6 and above the yarn guide roller 11.

[0076] like Figure 4As shown, the thread processing unit 21 has multiple thread travel spaces 31, multiple thread guide paths 32, and multiple jet flow paths 33. The multiple thread travel spaces 31 extend along the thread travel direction and are arranged in a direction intersecting the thread travel direction (…). Figure 4 The threads are arranged at approximately equal intervals in the left-right direction. Furthermore, the spacing of the thread travel spaces 31 refers to the distance between the centers of adjacent thread travel spaces 31. Additionally, one of each of the interlacing plates 26 is formed. The thread travel spaces 31 are formed into approximately elliptical shapes with the left-right direction as the longer side when viewed from the thread travel direction. The thread travel spaces 31 extend along the entire length of the interlacing plate 26 in the thread travel direction and are open at both ends.

[0077] Multiple thread guide paths 32 are individually provided for multiple thread travel spaces 31 and are used to guide the thread Y into the thread travel space 31. The thread guide path 32 extends the entire length of the interlacing piece 26 in the thread travel direction and is open at both ends. In addition, the thread guide path 32 has a first thread path 36, a second thread path 37, and a third thread path 38.

[0078] The first thread path 36 is a gap formed between two adjacent interlocking plates 26, extending in the front-back direction in approximately the front half of the interlocking plate 26, with the front end in the front-back direction becoming the insertion port 36a of the thread Y.

[0079] The second thread path 37 connects to the rear end of the first thread path 36 in the front-rear direction and extends to the right from the portion connected to the first thread path 36. The third thread path 38 connects to the right end of the second thread path 37 and extends to the front in the front-rear direction from the portion connected to the second thread path 37. Then, the front end of the third thread path 38 in the front-rear direction connects to the thread travel space 31.

[0080] In addition, such as Figure 4 As shown, approximately half of the front surface of the interlocking sheet 26 in the front-rear direction, to the left of the approximately central portion, becomes an inclined surface 26a that is inclined relative to the left-right direction with its left end further back than the approximately central portion. Furthermore, in this embodiment, the approximately central portion of the front surface of the interlocking sheet 26 is a portion to the right of the actual central portion. Additionally, approximately half of the front surface of the interlocking sheet 26 in the front-rear direction, to the right of the approximately central portion, becomes an inclined surface 26b that is inclined relative to the left-right direction with its right end further back than the approximately central portion. Thus, inclined surfaces 26a and 26b are located on both sides of the first thread path 36 in the left-right direction. Therefore, each thread Y, traveling approximately parallel to each other by being hooked by the first limiting thread guide 22 and the second limiting thread guide 23 (described later), is guided by inclined surfaces 26a and 26b and inserted into the first thread path 36.

[0081] Multiple jet flow paths 33 are individually provided relative to multiple thread travel spaces 31. Each jet flow path 33 is formed on each interlocking piece 26, extending in the front-rear direction, and its front end (front end) becomes a jet port 33a opening on the rear side wall of the connection portion of the second thread path 37 and the third thread path 38 in the front-rear direction. Thus, the jet port 33a is opposite to the thread travel space 31 in the front-rear direction via the third thread path 38. In addition, the rear end of the jet flow path 33 is connected to the fluid supply source 40 via the fluid supply flow path 43. A valve 39 is provided on the fluid supply flow path 43. Then, when the valve 39 is open, fluid such as air supplied from the fluid supply source 40 is supplied to the jet flow path 33 via the fluid supply flow path 43 and jetted from the jet port 33a of the jet flow path 33 into the thread travel space 31. As a result, a twisting flow is generated within the yarn travel space 31, which applies a bundled property to the filaments that form yarn Y and travel within the yarn travel space 31.

[0082] like Figure 2 , Figure 5 As shown, the first restrictive guide 22 is disposed on the front side surface of the substrate 20 in the front-rear direction, on the upstream side of the thread processing section 21 in the thread travel direction. Figure 2 As shown, the first guide wire restrictor 22 has a plurality of first grooves 22a arranged at equal intervals in the left-right direction of the arrangement of the plurality of wires Y. The spacing of the first grooves 22a refers to the distance between the centers of adjacent first grooves 22a. The spacing of the plurality of first grooves 22a is the same as the spacing of the plurality of wire travel spaces 31. The first grooves 22a open towards the front side in the front-back direction. In addition, the direction towards the front side in the front-back direction corresponds to the opening direction of the first grooves 22a of the present invention. In addition, as Figure 5 As shown, when viewed from the left-right direction, the first limiting guide 22 is positioned offset from the thread channel of the multiple threads Y hooked to the first thread holding member 24 (described later) in the thread holding position. In other words, the first limiting guide 22 is positioned in the front-back direction further back than the thread channel of the multiple threads Y hooked to the first thread holding member 24 in the thread holding position.

[0083] like Figure 2 , Figure 5 As shown, the second restrictive guide 23 is disposed on the front surface of the substrate 20 in the front-rear direction, at a portion downstream of the thread processing section 21 in the thread travel direction. Figure 2As shown, the second guide wire restrictor 23 has a plurality of second grooves 23a arranged in the left-right direction at the same spacing as the plurality of first grooves 22a. The spacing of the second grooves 23a refers to the distance between the centers of adjacent second grooves 23a. The second grooves 23a open towards the front side in the front-back direction. In addition, the direction towards the front side in the front-back direction corresponds to the opening direction of the second grooves 23a of the present invention.

[0084] The left-right positions of the plurality of first grooves 22a and the plurality of second grooves 23a are approximately the same. Then, the thread Y traveling in the thread travel direction passes between adjacent first grooves 22a and adjacent second grooves 23a, thereby restricting the left-right movement of the thread Y and defining the thread channel. Furthermore, the first limiting guide 22 and the second limiting guide 23 function to support the thread Y when applying a bundled structure to it in the thread processing unit 21. Additionally, "the left-right positions of the plurality of first grooves 22a and the plurality of second grooves 23a are approximately the same" includes cases where the left-right positions of the plurality of first grooves 22a and the plurality of second grooves 23a are exactly the same, and cases where they are slightly offset.

[0085] The first thread holding member 24 is capable of holding multiple threads Y hooked onto the first limiting thread guide 22. The first thread holding member 24 is a plate-shaped member extending in the left-right direction. The first thread holding member 24 has multiple first holding grooves 24a with a left-right spacing equal to the left-right spacing of multiple first grooves 22a. The spacing of the first holding grooves 24a refers to the distance between the centers of adjacent first holding grooves 24a. The left-right movement of the multiple threads Y hooked onto the first holding grooves 24a is restricted. The left-right positions of the multiple first grooves 22a and the multiple first holding grooves 24a are approximately the same. The first thread holding member 24 is capable of hooking multiple threads Y onto the multiple first holding grooves 24a at the following positions (refer to...). Figure 2 as well as Figure 5 The handover completion position of the multiple wires and the first Y-direction limiting guide 22 (refer to the handover completion position). Figure 3 as well as Figure 6 The movement between () and (). Additionally, the wire channel when multiple wires Y are hooked on the first wire guide 22 and the second wire guide 23 refers to (). Figure 6 The thread channel of thread Y is shown. In addition, "the positions of the plurality of first grooves 22a and the plurality of first holding grooves 24a in the left and right directions are approximately the same" includes the case where the positions of the plurality of first grooves 22a and the plurality of first holding grooves 24a in the left and right directions are exactly the same, and the case where they are slightly offset.

[0086] like Figure 2 as well as Figure 5As shown, when the first thread holding member 24 is in the thread-hanging position, it is located downstream of the first thread guide 22 in the thread travel direction and in front of the thread processing section 21 in the front-back direction. Furthermore, as... Figure 5 As shown, when the first thread holding member 24 is in the thread-hanging position, when viewed from the left and right direction, it deviates forward in the forward direction from the thread channel where multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23. That is, the thread-hanging position of the first thread holding member 24 is such that, when viewed from the left and right direction, the first thread holding member 24 deviates from the opening direction of the first groove 22a from the thread channel where multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23. Furthermore, as... Figure 3 as well as Figure 6 As shown, when the first thread holding member 24 is in the handover completion position, it is located upstream of the first limiting thread guide 22 in the thread travel direction and behind the first limiting thread guide 22 in the front-back direction. To elaborate further, the handover completion position of the first thread holding member 24 is the position where the first thread holding member 24 retracts from the thread channel after hooking multiple threads Y onto the first limiting thread guide 22 and the second limiting thread guide 23. During its movement from the thread-hooking position to the handover completion position, the first thread holding member 24 hands over the multiple threads Y to the corresponding multiple first slots 22a.

[0087] The second thread holding member 25 is capable of holding multiple threads Y hooked onto the second thread guide 23. The second thread holding member 25 is disposed downstream of the first thread holding member 24 in the thread travel direction. The second thread holding member 25 is a plate-shaped member extending in the left-right direction. The second thread holding member 25 has multiple second holding grooves 25a with a left-right spacing equal to the left-right spacing of the multiple second grooves 23a. The spacing of the second holding grooves 25a refers to the distance between the centers of adjacent second holding grooves 25a. The left-right movement of the multiple threads Y hooked onto the second holding grooves 25a is restricted. The left-right positions of the multiple second grooves 23a and the multiple second holding grooves 25a are approximately the same. The second thread holding member 25 is capable of hooking multiple threads Y onto the multiple second holding grooves 25a at the following positions (refer to...). Figure 2 as well as Figure 5 The handover completion position of the multiple wires and the Y-direction second limiting guide 23 (refer to the handover completion position). Figure 3 as well as Figure 6 The two slots move between each other. In addition, "the left and right positions of the multiple second slots 23a and the multiple second holding slots 25a are approximately the same" includes the case where the left and right positions of the multiple second slots 23a and the multiple second holding slots 25a are exactly the same, as well as the case where they are slightly offset.

[0088] like Figure 2 as well as Figure 5 As shown, when the second thread holding member 25 is in the thread-hanging position, it is located upstream of the second thread guide 23 in the thread travel direction, downstream of the first thread holding member 24, and in front of the thread processing section 21 in the front-back direction. Furthermore, as... Figure 5 As shown, when the second thread holding member 25 is in the thread-hanging position, when viewed from the left and right direction, it deviates forward in the forward-backward direction from the thread channel when multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23. That is, the thread-hanging position of the second thread holding member 25 is such that, when viewed from the left and right direction, the second thread holding member 25 deviates from the opening direction of the second groove 23a from the thread channel when multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23. Furthermore, as... Figure 3 as well as Figure 6 As shown, when the second thread holding member 25 is in the handover completion position, it is located downstream of the second limiting thread guide 23 in the thread travel direction and behind the second limiting thread guide 23 in the front-back direction. To elaborate further, the handover completion position of the second thread holding member 25 is the position where the second thread holding member 25 retracts from the thread channel after hooking multiple threads Y onto the first limiting thread guide 22 and the second limiting thread guide 23. During its movement from the thread-hooking position to the handover completion position, the second thread holding member 25 hands over the multiple threads Y to the corresponding multiple second slots 23a.

[0089] like Figure 2 as well as Figure 5 As shown, the first thread holding member 24 in the thread-hanging position and the second thread holding member 25 in the thread-hanging position are adjacent to each other in the thread travel direction. Here, "adjacent to each other" means that the distance between the front end of the first thread holding member 24 in the thread-hanging position and the front end of the second thread holding member 25 in the thread-hanging position is 0 to 10 mm.

[0090] In addition, such as Figure 5As shown, when viewed from the left and right, the angle x formed by the depth direction of the first holding groove 24a of the first thread holding member 24 in the thread-hanging position (i.e., the first depth direction D1) and the depth direction of the second holding groove 25a of the second thread holding member 25 in the thread-hanging position (i.e., the second depth direction D2) is an acute angle. Specifically, when viewed from the left and right, the angle x formed by the first depth direction D1 and the second depth direction D2 is preferably 15 degrees or more, for example, 20 degrees. In addition, in this embodiment, the first depth direction D1 is a direction parallel to the front-back direction, and the second depth direction D2 is a direction inclined relative to the front-back direction with the front side above and the rear side below (see reference). Figure 5 ).

[0091] Moreover, such as Figure 5 As shown, in the first depth direction D1, the front end of the second thread holding member 25 in the thread-hanging position is located further forward of the opening side of the first holding groove 24a than the front end of the first thread holding member 24 in the thread-hanging position. That is, in this embodiment, in the front-rear direction, the front end of the second thread holding member 25 in the thread-hanging position is located further forward than the front end of the first thread holding member 24 in the thread-hanging position.

[0092] The linkage mechanism 30 is linked to the movement between the wire-hanging position and the handover completion position of the first wire holding member 24, and the movement between the wire-hanging position and the handover completion position of the second wire holding member 25. For example... Figure 7 As shown, the linkage mechanism 30 has a first swing arm 41 that can rotate about a first swing axis 51 in the left-right direction, and a second swing arm 42 that can rotate about a second swing axis 52 in the left-right direction.

[0093] like Figure 2 As shown, the first swing arm 41 cantileverly supports the left end of the first thread holding member 24 via its front end portion. By rotating the first swing arm 41 around the first swing axis 51, the first thread holding member 24 can swing between the thread-hanging position and the completed transfer position (see reference). Figure 7 (Solid arrow). When the first thread holding member 24 is in the thread-hanging position, the first swing arm 41 is in a state of extending in the front-back direction (see reference). Figure 7 When the first thread holding member 24 is in the handover completion position, the first swing arm 41 extends diagonally forward and upward (see reference). Figure 8 ).

[0094] In addition, such as Figure 2As shown, the second swing arm 42 cantileverly supports the left end of the second wire holding member 25 via its front end portion. By rotating the second swing arm 42 around the second swing axis 52, the second wire holding member 25 can swing between the wire-hanging position and the handover completion position (see reference). Figure 7 (Solid arrow). When the second wire holding member 25 is in the wire-hanging position, the second swing arm 42 is in a state of extending in the front-back direction (see reference). Figure 7 When the second thread holding member 25 is in the handover completion position, the second swing arm 42 extends diagonally forward and downward (see reference). Figure 8 ).

[0095] Moreover, such as Figure 7 As shown, the first swing arm 41 includes a first gear 53 with four teeth, and the second swing arm 42 includes a second gear 54 with five teeth. The first gear 53 and the second gear 54 mesh with each other. However, the number of teeth constituting the first gear 53 may not be four. Similarly, the number of teeth constituting the second gear 54 may not be five.

[0096] The linkage mechanism 30 causes the first swing arm 41 and the second swing arm 42 to rotate in a linked manner through the meshing of the first gear 53 and the second gear 54. The linkage mechanism 30 may include, for example, a motor (not shown) that drives the rotation of either the first swing shaft 51 or the second swing shaft 52. However, the linkage mechanism 30 is not limited to having a motor; for example, it may also have a handle (not shown) mounted on either the first swing arm 41 or the second swing arm 42. In this case, the operator starts the rotation of either the first swing arm 41 or the second swing arm 42 by pulling the handle. Then, the first gear 53 meshes with the second gear 54, and thus the other swing arm 41 or the second swing arm 42 also rotates in a linked manner.

[0097] (Hanging the wire to the wire processing device 7)

[0098] Next, the specific sequence of hooking multiple yarns Y onto the first limiting guide 22 and the second limiting guide 23 of the yarn handling device 7 will be explained. In the spinning production equipment 1, after the yarn is hooked onto the guiding guide 6, it is hooked onto the two limiting guides of the yarn handling device 7. The hooking of the yarns onto the first limiting guide 22 and the second limiting guide 23 of the yarn handling device 7 is performed, for example, using a suction gun 80. The suction gun 80 attracts and gathers the multiple yarns Y.

[0099] Before the yarn is attached to the yarn handling device 7, the linkage mechanism 30 pre-moves the first yarn holding member 24 and the second yarn holding member 25 to the yarn-attaching position (see reference). Figure 2 Then, as Figure 5As shown, the operator hooks the multiple threads Y, which are concentrated and attracted by the suction gun 80, onto the first holding slots 24a of the first thread holding member 24 and the second holding slots 25a of the second thread holding member 25. At this time, the operator observes the first thread holding member 24 and the second thread holding member 25, which are set at a height slightly above their own line of sight, while hooking the threads onto the first thread holding member 24 and the second thread holding member 25.

[0100] The following describes in detail the actions of the operator when using the suction gun 80 to attach multiple threads Y to the first thread holding member 24 and the second thread holding member 25. The operator observes the first thread holding member 24 and the second thread holding member 25 by peering at the bottom of the first holding groove 24a from slightly below the thread processing device 7. In other words, the operator observes the first thread holding member 24 and the second thread holding member 25 from a slightly lower position than the thread processing device 7, with their line of sight as parallel as possible to the first depth direction D1 of the first thread holding member 24. Here, as described above, in the front-back direction, the front end of the second thread holding member 25 in the thread-attached position is located further forward than the front end of the first thread holding member 24 in the thread-attached position (see reference). Figure 5 Therefore, when an operator observes the first thread holding member 24 and the second thread holding member 25 in the thread-hanging position from a slightly lower angle than the thread handling device 7, part or all of the first thread holding member 24 is hidden inside the second thread holding member 25. Furthermore, as described above, the angle x formed by the first depth direction D1 of the first holding groove 24a of the first thread holding member 24 in the thread-hanging position and the second depth direction D2 of the second holding groove 25a of the second thread holding member 25 in the thread-hanging position is 20 degrees (see reference). Figure 5Therefore, when the operator observes the first thread holding member 24 and the second thread holding member 25 by peering into the bottom of the first holding groove 24a, the operator sees the second thread holding member 25. Then, for the second thread holding member 25, the bottom portion of the second holding groove 25a and the portion that is not a groove are not aligned in a straight line. Therefore, the operator can easily distinguish the grooved portion and the non-grooved portion of the second holding groove 25a. Thus, the operator adjusts the position of the suction gun 80 to match the spacing of the easily identifiable second holding grooves 25a with the spacing of the multiple threads Y attracted by the suction port 81 of the suction gun 80, while attaching threads to the first thread holding member 24 and the second thread holding member 25. Furthermore, as mentioned above, the first thread holding member 24 in the thread-attached position and the second thread holding member 25 in the thread-attached position are adjacent to each other in the thread travel direction. Therefore, the hanging of multiple threads Y towards the first thread holding member 24 and the hanging of threads towards the second thread holding member 25 are carried out approximately simultaneously.

[0101] Next, the first thread holding member 24, which is in the thread-hanging position, is moved toward the handover completion position via the linkage mechanism 30, and the second thread holding member 25, which is in the thread-hanging position, is moved toward the handover completion position in conjunction with this. Specifically, when viewed from the right side in the left-right direction, the first swing arm 41 rotates counterclockwise around the first swing axis 51. Figure 7 The solid arrow in the image rotates, causing the first thread holding member 24 to swing from the thread-hanging position toward the handover completion position. Additionally, when viewed from the right side in a left-right direction, the second swing arm 42 rotates clockwise about the second swing axis 52. Figure 7 The solid arrow in the middle rotates, thereby causing the second thread holding member 25 to swing from the thread hanging position toward the handover completion position.

[0102] The multiple threads Y held by the first thread holding member 24 are transferred to the first slots 22a of the first thread guide 22 as the first thread holding member 24 moves from the thread holding position to the transfer completion position. Specifically, after the thread Y hooked in the first holding slot 24a contacts the bottom of the first slot 22a of the first thread guide 22, the first thread holding member 24 moves further toward the transfer completion position, thereby transferring the thread Y hooked in the first holding slot 24a to the first slot 22a. Thus, the thread hanging operation to the first thread guide 22 is completed.

[0103] The multiple threads Y held by the second thread holding member 25 are transferred to the second slots 23a of the second limiting thread guide 23 midway as the second thread holding member 25 moves from the thread-hanging position to the transfer completion position. Specifically, after the thread Y hooked in the second holding slot 25a contacts the bottom of the second slot 23a of the second limiting thread guide 23, the second thread holding member 25 moves further toward the transfer completion position, thereby transferring the thread Y hooked in the second holding slot 25a to the second slot 23a. Thus, the thread-hanging operation to the second limiting thread guide 23 is completed.

[0104] Multiple threads Y hooked on the first limiting thread guide 22 and the second limiting thread guide 23 are guided by the inclined surfaces 26a and 26b of the thread processing section 21 and inserted into the first thread path 36.

[0105] (Effect)

[0106] The thread processing apparatus 7 of this embodiment includes: a first thread guide 22 disposed upstream of the thread processing unit 21 in the thread travel direction, and a second thread guide 23 disposed downstream; a first thread holding member 24 capable of holding multiple threads Y hooked onto the first thread guide 22; and a second thread holding member 25 capable of holding multiple threads Y hooked onto the second thread guide 23. The first thread holding member 24 has a plurality of first holding grooves 24a and is movable between a thread hanging position and a transfer completion position. The second thread holding member 25 has a plurality of second holding grooves 25a and is movable between a thread hanging position and a transfer completion position. The first thread holding member 24 in the thread hanging position and the second thread holding member 25 in the thread hanging position are adjacent to each other in the thread travel direction. Furthermore, when viewed from the left and right, the angle x formed by the depth direction of the first holding groove 24a of the first wire holding member 24 in the wire hanging position, i.e., the first depth direction D1, and the depth direction of the second holding groove 25a of the second wire holding member 25 in the wire hanging position, i.e., the second depth direction D2, is an acute angle.

[0107] According to this embodiment, when viewed from the left and right, the angle x formed by the first depth direction D1 of the first holding groove 24a of the first thread holding member 24 in the thread-hanging position and the second depth direction D2 of the second holding groove 25a of the second thread holding member 25 in the thread-hanging position is an acute angle. Therefore, even if the operator observes by peering at the bottom of the first holding groove 24a of the first thread holding member 24 in the thread-hanging position in order to match the spacing of the multiple threads Y concentratedly attracted by the suction gun 80 with the spacing of the first holding groove 24a, the operator will also observe the second thread holding member 25 in the thread-hanging position from the direction intersecting the second depth direction D2 of the second holding groove 25a. That is, when the operator observes the two thread holding members in the thread-hanging position, regarding the second thread holding member 25, the bottom part of the second holding groove 25a and the part that is not a groove are not arranged in a roughly straight line, making it easy to distinguish the part that is a groove of the second holding groove 25a and the part that is not a groove. In this embodiment, the two thread holding members at the thread hanging position are adjacent to each other in the thread travel direction. Therefore, the operator can hook multiple threads Y into each holding groove of the two thread holding members based on the distance between the second holding grooves 25a of the second thread holding member 25, which are easily identifiable as grooves. This makes the thread hanging operation to the two thread holding members easier. As a result, the thread hanging operation to the two limiting guides on the upstream and downstream sides of the thread processing unit 21 of the thread processing device 7, which are arranged in the thread travel direction, becomes easier.

[0108] Furthermore, in this embodiment, in the first depth direction D1, the front end of the second thread holding member 25 in the thread-hanging position is located closer to the opening side of the first holding groove 24a than the front end of the first thread holding member 24 in the thread-hanging position. During thread-hanging operations, when the operator observes the two thread holding members in the thread-hanging position, it is difficult to determine the line of sight when both thread holding members enter the field of vision. That is, even if one thread holding member is focused on, the other thread holding member will also enter the field of vision, and the line of sight is easily deflected. Therefore, thread-hanging operations towards the thread holding members become difficult. According to this embodiment, the operator can hide part or all of the first thread holding member 24 inside the second thread holding member 25, thus being able to observe both thread holding members in the thread-hanging position. Therefore, even when focusing on the second thread holding member 25, part or all of the first thread holding member 24 can be removed from the field of vision, suppressing the operator's line of sight deflection. This makes thread-hanging operations towards the two thread holding members easier.

[0109] Furthermore, in this embodiment, the angle x formed by the first depth direction D1 and the second depth direction D2 when viewed from the left and right is 20 degrees. When the angle x formed by the first depth direction D1 and the second depth direction D2 when viewed from the left and right is too small, there is a limit to the improvement of the visual recognizability of the spacing between the holding grooves of each wire holding member in the wire-hanging position. According to this embodiment, the angle x formed by the first depth direction D1 and the second depth direction D2 when viewed from the left and right is 15 degrees or more. Therefore, when observing by peeking at the bottom of the first holding groove 24a of the first wire holding member 24 in the wire-hanging position, it is possible to clearly distinguish the bottom part of the second holding groove 25a of the second wire holding member 25 in the wire-hanging position from the part that is not a groove. As a result, the wire-hanging operation to the two wire holding members becomes easier.

[0110] Furthermore, in this embodiment, the first thread holding member 24 and the second thread holding member 25 are plate-shaped members. According to this embodiment, by reducing the thickness of the first thread holding member 24 and the second thread holding member 25, which are composed of plate-shaped members, the first thread holding member 24 and the second thread holding member 25, which are in the thread hanging position, can be brought closer together in the thread travel direction. Therefore, it is easier to perform the operation of hooking multiple threads Y together in the multiple holding slots of each thread holding member.

[0111] Furthermore, in this embodiment, the thread handling apparatus 7 includes a linkage mechanism 30 that links the movement of the first thread holding member 24 between the thread hanging position and the handover completion position, and the movement of the second thread holding member 25 between the thread hanging position and the handover completion position. If only the thread Y is handed over from one thread holding member to the limiting guide first, during the subsequent handover of the thread Y from the other thread holding member to the limiting guide, the thread Y may float up and detach from the limiting guide where the handover of the thread Y has already been completed. According to this embodiment, the handover of the thread Y from the first thread holding member 24 to the first limiting guide 22 and the handover of the thread Y from the second thread holding member 25 to the second limiting guide 23 can be performed at the same timing. Therefore, the thread hanging operation to both limiting guides can be performed more reliably.

[0112] In this embodiment, the linkage mechanism 30 includes: a first swing arm 41, rotatable about a first swing axis 51 in the left-right direction, supporting the first thread holding member 24 for swinging; and a second swing arm 42, rotatable about a second swing axis 52 in the left-right direction, supporting the second thread holding member 25 for swinging. The first swing arm 41 includes a first gear 53, and the second swing arm 42 includes a second gear 54. The linkage mechanism 30 then rotates the first swing arm 41 and the second swing arm 42 in a linked manner through the meshing of the first gear 53 and the second gear 54, thereby linking the movement of the first thread holding member 24 with the movement of the second thread holding member 25. According to this embodiment, the first swing arm 41 and the second swing arm 42 rotate in a linked manner through the meshing of the first gear 53 and the second gear 54, thereby enabling the first thread holding member 24 and the second thread holding member 25 to swing in a linked manner. Therefore, complex configurations and controls are not required to enable the first wire holding component 24 and the second wire holding component 25 to move in tandem.

[0113] Furthermore, in this embodiment, the thread holding member 24 is positioned such that, when viewed from the left and right, it deviates from the opening direction of the thread channel when multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23, towards the opening direction of the first groove 22a. Similarly, the thread holding member 25 is positioned such that, when viewed from the left and right, it deviates from the opening direction of the thread channel when multiple threads Y are hooked on the first thread guide 22 and the second thread guide 23, towards the opening direction of the second groove 23a. According to this embodiment, when multiple threads Y are hooked onto the first thread holding member 24 and the second thread holding member 25 in their thread holding positions, it is possible to prevent accidental hooking of threads Y into grooves in the multiple first grooves 22a of the first thread guide 22 and the multiple second grooves 23a of the second thread guide 23 that should not normally be hooked. Then, by moving the first thread holding member 24 to the handover completion position while the first thread holding member 24 holds the thread Y and the first thread guide 22 is not hooked with the thread Y, the thread Y can be hooked more reliably in the first slots 22a of the plurality of first slots 22a that should be hooked with the thread Y. Similarly, by moving the second thread holding member 25 to the handover completion position while the second thread guide 23 holds the thread Y and the second thread guide 23 is not hooked with the thread Y, the thread Y can be hooked more reliably in the second slots 23a of the plurality of second slots 23a that should be hooked with the thread Y.

[0114] Furthermore, in this embodiment, the first limiting guide 22 is positioned such that, when viewed from the left or right, it deviates from the thread channels of the plurality of threads Y hooked on the first thread holding member 24 in the thread-hanging position. According to this embodiment, when thread Y is hooked onto the first thread holding member 24 in the thread-hanging position, it is possible to further suppress the accidental hooking of thread Y into the first slot 22a of the plurality of first slots 22a of the first limiting guide 22, where thread Y should not normally be hooked.

[0115] (Modified Example)

[0116] Hereinafter, variations of the above-described embodiments will be described. However, descriptions of parts having the same structure as the above-described embodiments will be appropriately omitted, using the same reference numerals.

[0117] In the above embodiment, in the first depth direction D1, the front end of the second thread holding member 25 in the thread-hanging position is located further towards the opening side of the first holding groove 24a than the front end of the first thread holding member 24 in the thread-hanging position. However, in the second depth direction D2, the front end of the first thread holding member 24 in the thread-hanging position may also be located further towards the opening side of the second holding groove 25a than the front end of the second thread holding member 25 in the thread-hanging position. In other words, in the front-rear direction, the front end of the first thread holding member 24 in the thread-hanging position may also be located further forward than the front end of the second thread holding member 25 in the thread-hanging position.

[0118] In the above embodiment, when viewed from the left and right, the angle x formed by the first depth direction D1 and the second depth direction D2 is 15 degrees or more. However, when viewed from the left and right, the angle x formed by the first depth direction D1 and the second depth direction D2 can also be an acute angle less than 15 degrees.

[0119] In the above embodiment, the thread processing device 7 is a device for applying a bundled effect to multiple threads Y using the jetting action of compressed air. However, the thread processing device is not limited to this. The thread processing device may also include other devices that provide thread guides (a first thread guide and a second thread guide) on the upstream and downstream sides of the thread processing section in order to perform a prescribed treatment on multiple threads Y that are substantially parallel to each other and traveling at approximately equal intervals. For example, the thread processing device includes a device that serves as the thread processing section and has an oil nozzle for applying oil to the multiple threads Y, a tension sensor for detecting the tension of the multiple threads Y, etc.

[0120] In the above embodiment, the first thread holding member 24 swings via the first swing arm 41, and the second thread holding member 25 swings via the second swing arm 42. However, the first thread holding member 24 and the second thread holding member 25 are not limited to swinging motion. For example, the first thread holding member 24 can also move between the thread hanging position and the handover completion position by moving in the vertical direction and in the horizontal direction. Similarly, the second thread holding member 25 can also move between the thread hanging position and the handover completion position by moving in the vertical direction and in the horizontal direction. Specifically, the first thread holding member 24, which is in the thread hanging position, moves upward and then backward, thereby moving to the handover completion position. In addition, the second thread holding member 25, which is in the thread hanging position, moves downward and then backward, thereby moving to the handover completion position. Furthermore, the first thread holding member 24 can also move between the thread hanging position and the handover completion position by moving in the tilting direction. Similarly, the second thread holding member 25 can also move between the thread hanging position and the handover completion position by moving in the tilting direction.

[0121] In the above embodiment, the thread processing apparatus 7 has a linkage mechanism 30 that links the movement of the first thread holding member 24 and the second thread holding member 25. However, the thread processing apparatus 7 may also lack the linkage mechanism 30. In this case, the movement between the thread-holding position and the handover completion position of the first thread holding member 24 and the movement between the thread-holding position and the handover completion position of the second thread holding member 25 are performed independently.

[0122] In the above embodiment, a suction gun 80 is used to hang the threads onto the thread processing device 7. However, a guide hook that gathers multiple threads Y together can also be used for thread hanging.

[0123] In the above embodiment, the first thread holding member 24 in the thread-hanging position and the second thread holding member 25 in the thread-hanging position are positioned downstream of the first thread guide 22 and upstream of the second thread guide 23 in the thread-tracing direction. However, the first thread holding member 24 and the second thread holding member 25 in the thread-hanging position may also be positioned upstream of the first thread guide 22 in the thread-tracing direction, or downstream of the second thread guide 23 in the thread-tracing direction.

[0124] In the above embodiment, the yarn handling device 7 is positioned below the plurality of yarn guides 6 and above the yarn guide roller 11 in the spinning production equipment 1. However, the position of the yarn handling device 7 is not limited to this. When the spacing of multiple yarns on the upstream and downstream sides of the yarn travel direction becomes different due to the use of a suction gun 80 or the like for yarn hanging operations, the configuration of the present invention can be effective when the yarn Y is hooked onto two limiting yarn guides (first limiting yarn guide and second limiting yarn guide) of multiple grooves (first groove and second groove) that are separately arranged in the yarn travel direction and have the same spacing in the arrangement direction.

[0125] In the above embodiment, multiple threads Y converging toward the suction gun 80 are arranged in multiple thread travel spaces 31 formed in the thread processing unit 21. That is, the spacing of the multiple threads Y in the arrangement direction is such that the spacing on the upstream side in the thread travel direction is greater than the spacing on the downstream side. However, the spacing of the multiple threads Y arranged in the multiple thread travel spaces 31 in the arrangement direction may also be such that the spacing on the upstream side in the thread travel direction is smaller than the spacing on the downstream side.
