Yarn winder

Abstract

Provided is a yarn winder that reduces the likelihood of a yarn end on the side of a formed package being wound into an empty bobbin. A spinning draw frame (1) includes a bobbin support (24A, 24B), a switching section, a partition plate (65), and a control section (26). A first imaginary line segment (VLS1) is defined in a completed state in which switching operation is completed, a package (P) is held by the bobbin support (24A), and the partition plate (65) is positioned at a partition position. Two imaginary tangent lines (a first imaginary tangent line (VLT1) and a second imaginary tangent line (VLT2)) that are parallel to the first imaginary line segment (VLS1) and that are tangent to the outer periphery of the bobbin support (24B) are defined. The partition plate (65) extends so as to cross both of the two imaginary tangent lines and is separated from a yarn holding guide (44). The control section (26) causes the partition plate (65) to be positioned at the partition position after completion of the switching operation and causes the yarn holding guide (44) to start moving from a holding position toward a retreat position before the partition plate (65) reaches the partition position.

Description

Technical Field

[0001] This invention relates to a yarn winding machine. Background Technology

[0002] Patent Document 1 discloses a spinning take-up machine (thread take-up machine) comprising two bobbin supports extending axially. Each bobbin support rotats. A package is formed by winding a traveling thread onto a bobbin supported by one of the two bobbin supports. At the end of package formation, a switching operation (transferring the thread from the package to an empty bobbin held by the other bobbin support) is performed in the thread take-up machine. More specifically, while the traveling thread is being wound onto the package, it is hooked onto an empty bobbin via a thread transfer device (switching unit). Tension is applied to the thread hooked onto the empty bobbin, causing the thread to break from the package. This switching operation is performed.

[0003] Here, the switching unit has a first rotating plate that separates the space between one bobbin support and the other bobbin support. In addition to the first rotating plate, a second rotating plate is also provided to separate the aforementioned space. At the moment the switching operation is completed, the front ends of the first rotating plate and the front ends of the second rotating plate are positioned facing each other. At this time, when viewed axially, the space is substantially entirely separated by the first and second rotating plates. This prevents the problem of the coiled end (thread tip) of a broken thread getting caught in the empty bobbin side.

[0006] Patent Document 1: Japanese Patent Application Publication No. 7-138808 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] Between the first and second rotating plates mentioned above, a small gap is created to prevent interference between them. This gap is located on or near the line segment connecting the center of one bobbin support to the center of the other bobbin support. Therefore, the thread end on the coiled side may be wound into the empty bobbin side through this gap.

[0009] The purpose of this invention is to reduce the possibility that the filaments on the coil side will be wound into the empty tube side after the coil is formed.

[0010] Methods for solving problems

[0011] The first invention's thread winding machine is characterized by comprising: a first bobbin support that holds a first bobbin carrying a traveling thread so as to be rotatable and extends along a predetermined axial direction; a second bobbin support arranged with the first bobbin support in a predetermined arrangement direction intersecting the axial direction, holding a second bobbin carrying the thread so as to be rotatable and extending along the axial direction; a switching unit having a thread holding portion capable of being positioned in a holding position for temporarily holding the traveling thread, and capable of performing a switching operation that switches the state of the first bobbin support and the second bobbin support from a state in which the thread is wound onto a rotating first bobbin to form a package to a state in which the thread is hooked onto a rotating empty second bobbin and the thread is disconnected from the package; and a separating portion capable of moving between a non-overlapping position when viewed from the axial direction and a separating position, wherein in the non-overlapping position the separating portion does not overlap with the travel track of the thread held by the thread holding portion in the holding position during the switching operation, and in the separating position the separating portion is in the state after the switching operation is completed. The system comprises: a separation drive that at least partially separates the space between the second bobbin and the package; a separation drive that drives the separation portion to move; a holding drive that, relative to the holding position, moves the yarn holding portion between a retracted position (separated from the separation position) and the holding position; and a control unit. In the completed state where the switching operation is completed, the package is held on the first bobbin support, and the separation portion is located in the separation position, the separation portion, when viewed from the axial direction, extends transversely through both the first imaginary tangent line parallel to and tangent to the outer periphery of the second bobbin support and the second imaginary tangent line, and is separated from the yarn holding portion. The control unit controls the separation drive to position the separation portion in the separation position after the switching operation is completed, and controls the holding drive to start moving the yarn holding portion from the holding position toward the retracted position before the separation portion reaches the separation position.

[0012] According to the present invention, it is possible to achieve a state where the separating portion does not interfere with the yarn holding portion, while the separating portion can extensively block the area where the second bobbin is particularly close to the winding. Therefore, the possibility of the yarn end on the winding side at the end of formation being wound into the empty bobbin side (second bobbin side) can be reduced. In addition, by moving the yarn holding portion to the retracted position after the switching operation is completed, interference between the separating portion and the yarn holding portion can be more reliably avoided. Furthermore, after the switching operation is completed, the separating portion is placed in the separating position, and before the separating portion reaches the separating position, the yarn holding portion begins to move from the holding position toward the retracted position. Thus, interference between the separating portion and the yarn holding portion after the switching operation is completed can be reliably avoided.

[0013] The second invention's thread winding machine is characterized in that, in the first invention, in the completed state, the dividing portion is arranged such that it surrounds the second bobbin support within an angle range of 90 degrees or more in the circumferential direction of the second bobbin support.

[0014] In this invention, the second bobbin can be surrounded over a large area in the circumferential direction of the second bobbin support. Therefore, the possibility of the yarn end on the winding side being wound into the second bobbin side can be further effectively reduced.

[0015] The third invention's thread winding machine is characterized in that, in the first or second invention, when viewed from the axial direction, the two imaginary tangents include a first imaginary tangent and a second imaginary tangent. In the completed state, a portion of the first imaginary line segment in the winding rotates in a manner that moves from the first imaginary tangent side to the second imaginary tangent side. The first angle formed between the second imaginary line segment (the end of the dividing portion closer to the first imaginary tangent side than the first imaginary line segment) and the center of the rotation axis of the second bobbin support, and the first imaginary line segment, is greater than the second angle formed between the third imaginary line segment (the end of the dividing portion closer to the second imaginary tangent side than the first imaginary line segment and the center of the rotation axis of the second bobbin support) and the first imaginary line segment.

[0016] The filament on the winding side extends downstream in the direction of winding rotation, with its tail pulled towards the end. In this invention, the filament near the first imaginary segment extends longer towards the first imaginary tangent side. Regarding this, according to the invention, since the first angle is larger than the second angle, the separator is configured to extend longer towards the first imaginary tangent side. Therefore, the separator can effectively prevent the longer filament from being wound into the second bobbin side.

[0017] The fourth invention's thread winding machine is characterized in that, in any of the first to third inventions, the separating portion when in the separating position is arranged radially on the second bobbin support at a position farther away from the second bobbin support than the thread holding portion when holding the thread during the switching operation.

[0018] After the switching operation is completed, a new roll is formed by winding the yarn onto the second bobbin, and the diameter of this roll increases over time. Therefore, to avoid interference between this roll and the separator, the separator located at the separator position needs to be moved away from the roll at an appropriate timing. On the other hand, since there is a possibility of unexpected delays in the timing of the roll being retrieved after formation, it is preferable to keep the separator in the separator position for as long as possible after the switching operation is completed. In this respect, in this invention, the separator located at the separator position is positioned radially away from the second bobbin support. Therefore, the separator can remain in the separator position for an extended period.

[0019] The fifth invention's thread winding machine is characterized in that, in any of the first to fourth inventions, the switching unit is configured such that, during the switching operation, the thread is disconnected by applying tension to the thread traveling toward the package via the second bobbin; the thread holding unit is disposed between the second bobbin and the package in the thread's travel direction during the switching operation, and is configured to bend the thread channel through which the thread travels; and, in the radial direction of the second bobbin support, it is located closer to the second bobbin support than the track moved by the separating part.

[0020] During the switching operation, the thread between the coil and the second bobbin is broken by tension, thus separating into a thread end on the coil side and a thread end on the bobbin side. The thread end on the second bobbin side is not wound into the second bobbin, and therefore is preferably as short as possible. Here, the aforementioned tension is forcefully applied to the portion of the thread that is held and bent by the thread holding part. Therefore, the location where the thread breaks is approximately the same as the location where the thread holding part is located. In this invention, during the switching operation, the thread holding part is located close to the second bobbin support. Therefore, the thread end on the second bobbin side of the broken thread can be shortened.

[0021] The sixth invention is characterized in that, in any of the first to fifth inventions, it includes a wire-hanging execution unit, which is configured to perform a wire-hanging action of hooking the wire onto the first bobbin in an empty state before the switching action is performed. The wire-hanging execution unit has a wire-holding part, which is configured to temporarily hold the wire during the wire-hanging action.

[0022] In this invention, the thread holding part can be used not only for switching operations but also for thread hanging operations. Therefore, both switching and thread hanging operations can be performed with a relatively small number of parts.

[0023] The seventh invention is characterized in that, in the sixth invention, the wire-hanging execution unit has: a transfer portion configured to temporarily hold the wire during the wire-hanging action for transferring the wire to the wire-holding portion; and a support portion supporting the transfer portion, the support portion supporting the separation portion in addition to supporting the transfer portion.

[0024] In this invention, the support portion supports both the junction portion and the partition portion. Therefore, compared to a configuration where the junction portion and the partition portion are supported by different components, it is possible to suppress an increase in the number of components.

[0025] The thread winding machine of the eighth invention is characterized in that, in the seventh invention, a junction drive source for driving the junction portion to move and a separation drive source for driving the separation portion to move are respectively provided.

[0026] The present invention is effective when the movement of the junction part is very different from the movement of the separation part.

[0027] The thread winding machine of the ninth invention is characterized in that, in the eighth invention, the junction portion is configured to be able to move in parallel, and the separator portion is configured to be able to swing.

[0028] If a single drive source were to be used to achieve both the parallel movement of the junction and the swinging motion of the partition, a complex mechanism would likely be required. In this invention, the junction and partition are moved by different drive sources. Therefore, the complexity of the mechanism can be reduced.

[0029] The thread winding machine of the tenth invention is characterized in that, in any of the first to ninth inventions, it includes a turntable, which is configured to support the first bobbin support and the second bobbin support so that they can revolve around the axial direction as the revolution axis, thereby allowing the positions of the first bobbin support and the second bobbin support to be interchanged.

[0030] In this invention, the positions of the first tube support and the second tube support can be easily changed using a known turntable.

[0031] The eleventh invention is characterized in that, in any of the first to tenth inventions, in the completed state, when viewed from the axial direction, the dividing portion extends transversely through both the third and fourth imaginary tangents that are parallel to the first imaginary line segment and tangent to the outer periphery of the second tube.

[0032] In this invention, the dividing portion can further and more extensively shield the area where the second bobbin is particularly close to the winding. Therefore, the possibility of the yarn end on the winding side at the end of the winding process being wound into the empty bobbin side (second bobbin side) can be further reduced.

Detailed Implementation

[0053] Next, embodiments of the present invention will be described. For ease of explanation, [the following will be described]. Figure 1 The directions shown are defined as front-back, left-right, up-down. Up-down direction ( Figure 1 The vertical direction (up and down on the paper) is the direction of gravity.

[0054] (Spinning traction machine)

[0055] Reference Figures 1-3 The composition of the spinning traction machine is explained. Figure 1 This is a side view of the spinning traction machine 1 (the yarn winding machine of the present invention) of this embodiment. Figure 2 This is the front view of the spinning traction machine 1. Figure 3 This is a block diagram showing the electrical configuration of the spinning traction machine 1. The spinning traction machine 1 draws multiple filaments Y spun from the spinning device 2, and winds the multiple filaments Y onto multiple bobbins B to form multiple packages P. The above-described operation of the spinning traction machine 1 will be referred to as the winding operation below. The spinning device 2 is, for example, a known melt spinning device. The spinning device 2 spins multiple filaments Y, for example, made of synthetic fibers such as polyester. The multiple filaments Y are, for example, multifilament yarns composed of multiple filaments (not shown). Alternatively, each filament Y may also be a monofilament yarn composed of a single filament.

[0056] like Figure 1 as well as Figure 2 As shown, the spinning traction machine 1 includes, for example, a first guide roller 11, a second guide roller 12, and a take-up device 13. The first guide roller 11 is a roller whose axial direction is generally parallel to, for example, the left-right direction. The first guide roller 11 is driven to rotate by a motor (not shown). Thus, the first guide roller 11 feeds multiple yarns Y to the second guide roller 12. The second guide roller 12 is a roller whose axial direction is generally parallel to, for example, the left-right direction. The second guide roller 12 is positioned, for example, above and behind the first guide roller 11. The second guide roller 12 is driven to rotate by a motor (not shown). Thus, the second guide roller 12 feeds multiple yarns Y to the take-up device 13.

[0057] In the direction of travel, a suction device 14 is disposed immediately upstream of the first guide roller 11. The suction device 14 is configured to attract and hold the yarn Y spun from the spinning device 2. The suction device 14 is used, for example, to temporarily attract and hold the yarn Y before the yarn hanging process described later.

[0058] The second guide roller 12 is movably supported on the guide rail 15. The guide rail 15 extends obliquely upward and backward from the vicinity of the first guide roller 11. The second guide roller 12 is configured, for example, to be movable along the guide rail 15 by a moving mechanism (not shown). The moving mechanism is, for example, a roller moving motor 101 (see reference). Figure 3 ) drive. Thus, the second guide roller 12 can be driven at the winding position (refer to Figure 1 (solid line) and the position of the hanging wire (refer to) Figure 1 Move between the single-dot dashed lines. Roll position (refer to...) Figure 1 The solid line indicates the position of the second guide roller 12 during the winding operation. The wire-hanging position is closer to the first guide roller 11 than the winding position. The wire-hanging position is the position of the second guide roller 12 during the wire-hanging operation described later. The roller movement motor 101 is electrically connected to the control unit 26 (see reference). Figure 3 ).

[0059] The winding device 13 is configured to wind multiple yarns Y onto multiple bobbins B to form multiple packages P. The winding device 13 is, for example, positioned below the second guide roller 12. Figure 2As shown, the winding device 13 includes a frame 20, multiple fulcrum guides 21, multiple traverse guides 22, a turntable 23, two bobbin supports 24, and a contact roller 25.

[0060] The frame 20 is, for example, a component installed on the factory floor, for mounting or housing the various constituent parts of the winding device 13. Multiple pivot guides 21 are respectively provided corresponding to multiple yarns Y. Each pivot guide 21 is a guide that serves as a pivot point when the corresponding yarn Y traverses. The multiple pivot guides 21 are arranged in the front-to-back direction. Multiple traverse guides 22 are respectively provided corresponding to multiple yarns Y. Each traverse guide 22 is a guide for traversing the corresponding yarn Y. The multiple traverse guides 22 are arranged in the front-to-back direction. The multiple traverse guides 22 are, for example, provided by a traverse motor 102 (see reference). Figure 3 Driven by multiple traverse wire guides 22, for example, each having two blade wire guides 22a driven in opposite directions (see reference). Figure 8 The configuration of each traverse wire guide 22 is not limited to this.

[0061] The turntable 23 is a circular plate-shaped component whose axial direction is approximately parallel to the front-to-back direction. The turntable 23 is powered by a turntable motor 103 (see reference). Figure 3 Rotation drive. The turntable 23 supports the two tube supports 24 so that they can rotate.

[0062] The two tube supports 24 are configured to arrange and support multiple tubes B in the front-to-back direction, allowing them to rotate. Hereinafter, one of the two tube supports 24 will also be referred to as tube support 24A (see reference). Figure 2 The other side of the two tube supports 24 is also referred to as tube support 24B (see reference). Figure 2 The tube supports 24A and 24B are rotatably supported on the turntable 23. The tube supports 24A and 24B are symmetrically arranged about the rotation axis of the turntable 23 (see reference). Figure 2 For ease of explanation, the tube support 24A is assumed to correspond to the first tube support of the present invention, and the tube support 24B is assumed to correspond to the second tube support of the present invention. Tube supports 24A and 24B extend along the front-to-back direction (see reference). Figure 1 The extension direction of the tube support 24A corresponds to the axial direction of the invention. The extension direction of the tube support 24B is approximately parallel to the extension direction of the tube support 24A. Each tube support 24 supports a plurality of tubes B arranged in a front-to-back direction. The tube supports 24A and 24B are arranged in a direction orthogonal (intersecting) to the axial direction.

[0063] For ease of explanation, the plurality of bobbins B held in the bobbin support 24A are referred to as the plurality of bobbins B1 (the first bobbins of the present invention). The plurality of bobbins B held in the bobbin support 24B are referred to as the plurality of bobbins B2 (the second bobbins of the present invention). Furthermore, each of the two bobbin supports 24 is driven by a separate winding motor 104 (see reference 104). Figure 3 Rotation drive. More specifically, the bobbin support 24A is wound by the winding motor 104A (see reference). Figure 3 Rotary drive. The bobbin support 24B is driven by the winding motor 104B (see reference). Figure 3 Rotation drive.

[0064] Imagine a situation where multiple threads Y are wound onto multiple bobbins B held on one side of two bobbin supports 24 (see reference). Figure 1 as well as Figure 2 For ease of explanation, one of the tube supports 24 will be referred to as the upper tube support 24. Figure 1 and Figure 2 In the middle, the tube support 24A is the upper tube support 24.

[0065] The contact roller 25 is a roller positioned directly above the upper bobbin support 24. The axial direction of the contact roller 25 is approximately parallel to the front-to-back direction. The contact roller 25 contacts the surfaces of multiple rolls P supported on the upper bobbin support 24. Thus, the contact roller 25 applies contact pressure to the surfaces of the multiple rolls P during winding, adjusting the shape of each roll P.

[0066] The control unit 26 is a computer device that controls the operation of the spinning traction machine 1. The control unit 26 includes, for example, a CPU, ROM, and RAM (not shown). The control unit 26 is electrically connected to drive units such as the roller movement motor 101, the traverse motor 102, the turntable motor 103, and the two take-up motors 104. The control unit 26 is also electrically connected to other drive units described later.

[0067] In the winding device 13 with the above configuration, when the upper bobbin support 24 is driven to rotate, the yarn Y, which is traversed by the traversing guide 22, is wound onto the corresponding bobbin B to form a roll P. Furthermore, when multiple rolls P are fully wound, the turntable 23 rotates counterclockwise when viewed from the front. This swaps the vertical positions of the two bobbin supports 24. Hereinafter, for ease of explanation, the series of operations of the winding device 13, including the operation of swapping the vertical positions of the two bobbin supports 24 (described in detail later), will be referred to as the switching operation. Through the switching operation, the lower bobbin support 24 moves upward. Multiple yarns Y are wound onto the multiple empty bobbins B mounted on the upper bobbin support 24 to form multiple rolls P. Additionally, the bobbin support 24, which is mounted with multiple fully wound rolls P, moves downward. The multiple fully wound rolls P are recovered, for example, by a roll recovery device (not shown).

[0068] For ease of explanation, the rotation of the bobbin support 24 based on the take-up motor 104 will be referred to as the rotation of the bobbin support 24. The rotation of the bobbin B or the roll P based on the rotation of the bobbin support 24 will also be referred to as rotation. Furthermore, the rotation of the turntable 23 based on the turntable motor 103 (i.e., the movement of the bobbin support 24) will be referred to as the revolution of the bobbin support 24. The movement of multiple bobbins B or multiple rolls P based on the revolution of the bobbin support 24 will also be referred to as revolution. The axis of revolution of the bobbin support 24 (the direction of the revolution axis) is approximately parallel to the front-back direction. The bobbin supports 24A and 24B can be interchanged by rotating 180 degrees around the revolution axis.

[0069] However, during the switching operation, the yarn Y breaks between the fully wound package P and the empty bobbin B (details to be described later). The end of the yarn Y on the side of the finished package P (hereinafter referred to as the yarn end) may be wound into the side of the empty bobbin B. Therefore, in order to reduce the possibility that the yarn end on the side of the finished package P will be wound into the side of the empty bobbin B, the spinning traction machine 1 is configured as follows. Hereinafter, for ease of explanation, reducing the possibility that the yarn end on the side of the package P will be wound into the side of the empty bobbin will be referred to as winding-in suppression.

[0070] (Components used for hanging wires)

[0071] Although the direct correlation with winding suppression is low, multiple yarns Y need to be hooked onto the spinning traction machine 1 in order to initiate the winding operation. In this embodiment, the configuration for hooking the yarns is partially the same as the configuration for the switching operation. Therefore, before describing the configuration related to the switching operation, refer to... Figure 2 , Figures 4-8 The components used for hanging wires are explained. Figure 4 This is a diagram showing the operation of the multi-pivot wire guide 21. Figure 5 This is a front view of the transfer mechanism 27 and the thread holding mechanism 28, which will be described later. Figure 5 The circle shown by the double-dotted line is the orbit of the two tube supports 24 revolving around their axis (hereinafter referred to as orbit 100). Figure 6 This is a 3D diagram of the handover mechanism 27. Figure 7 (a) and Figure 7 (b) is a top view showing a portion of the transfer mechanism 27, and (c) is a view showing a portion of the wire holding mechanism 28. Figure 5 View VII(c) Figure 8 This is a diagram representing the wire-drawing mechanism 29, which will be described later.

[0072] The spinning traction machine 1 has the following components as components related to yarn hanging. Specifically, the spinning traction machine 1 includes a first guide roller 11, a second guide roller 12, multiple pivot yarn guides 21, a turntable 23, a transfer mechanism 27, a yarn holding mechanism 28, and a yarn pulling mechanism 29 (see reference). Figure 2 , Figures 4-8 In general, multiple yarns Y spun from the spinning device 2 are sequentially hooked by an operator onto the first guide roller 11, the second guide roller 12, and multiple fulcrum guides 21. Hereinafter, the operator's work during yarn hanging will be referred to as yarn hanging operation. Afterwards, the multiple yarns Y are transferred to the yarn holding mechanism 28 via the transfer mechanism 27, and then hooked onto multiple bobbins B via the yarn pulling mechanism 29. The turntable 23 rotates the bobbin support 24 to ensure that the multiple yarns Y are properly hooked onto the multiple bobbins B. Hereinafter, the actions of the turntable 23, the transfer mechanism 27, the yarn holding mechanism 28, and the yarn pulling mechanism 29 during yarn hanging will be referred to as yarn hanging operation. Details regarding the yarn hanging operation and yarn hanging operation will be described later. The turntable 23, the transfer mechanism 27, the yarn holding mechanism 28, and the yarn pulling mechanism 29 correspond to the yarn hanging execution unit of the present invention.

[0073] The position of the first guide roller 11 is fixed. As described above, the second guide roller 12 is movable between the winding position and the wire-hanging position (see reference). Figure 1 Multiple pivot wire guides 21 are configured to be able to operate at discrete positions (see reference). Figure 1 ) and set location (refer to) Figure 4 The multiple fulcrum guides 21 move between the discrete and convergent positions. The discrete position is the position of the multiple fulcrum guides 21 during the take-up operation. The convergent position is the position of the multiple fulcrum guides 21 when they are concentrated towards the front compared to the discrete position. The spacing between the multiple fulcrum guides 21 in the front-back direction is narrower in the convergent position than in the discrete position. The multiple fulcrum guides 21 are driven by the guide drive unit 105 (see reference 105). Figure 3 The guide wire drive unit 105 can move between discrete and aggregated positions. For example, it may also have a known cylinder (not shown). Alternatively, the guide wire drive unit 105 may also have a known pneumatic shifter (not shown). The configuration of the turntable 23 is as described above. Details of the operation will be described later.

[0074] The transfer mechanism 27 is used to transfer the portion of the multiple yarns Y that is downstream of the multiple fulcrum guides 21 in the traveling direction to the yarn holding mechanism 28. For example... Figure 2 As shown, the transfer mechanism 27 is, for example, located near the right end of the take-up device 13. Figure 5 and Figure 6As shown, the transfer mechanism 27 includes, for example, a support portion 31, two pneumatic shifters 32 (the transfer drive source of the present invention), an extension member 33, and a plurality of movable wire guides 34 (the transfer portion of the present invention). The two pneumatic shifters 32 supported on the support portion 31 drive the extension member 33, which supports the plurality of movable wire guides 34, to move.

[0075] like Figure 6 As shown, the support portion 31 has a support portion 31F disposed at the front end of the transfer mechanism 27 and a support portion 31R disposed at the rear end. The support portion 31F and the support portion 31R are generally columnar components extending in the vertical direction. The support portion 31F and the support portion 31R each support a pneumatic shifter 32.

[0076] Two pneumatic shifters 32 are drive sources for driving the extension member 33 and the plurality of movable wire guides 34 to move in a generally linear manner. The two pneumatic shifters 32 operate using compressed air. The two pneumatic shifters 32 are included in a movement drive unit 106 (see reference) that drives the extension member 33. Figure 3 The motion drive unit 106 is electrically connected to the control unit 26 (see reference). Figure 3 Two pneumatic shifters 32 are mounted on the support portion 31. For ease of explanation, the pneumatic shifter 32 mounted on the front side of the support portion 31F is referred to as pneumatic shifter 32F. The pneumatic shifter 32 mounted on the rear side of the support portion 31R is referred to as pneumatic shifter 32R. The pneumatic shifter 32F has a main body 32aF and a slider 32bF. The main body 32aF extends approximately vertically. The main body 32aF is slightly inclined to the left or right relative to the vertical direction. The slider 32bF is movably disposed on the main body 32aF and configured to move parallel to the length direction of the main body 32aF. The pneumatic shifter 32R has the same main body 32aR and slider 32bR as the pneumatic shifter 32F (detailed description omitted). The sliders 32bF and 32bR support the extension member 33 (see reference) approximately horizontally. Figure 6 ).

[0077] The extension member 33 is, for example, a long strip extending approximately horizontally in the front-to-back direction. The extension member 33 is moved by the movement drive unit 106. That is, the extension member 33 is fixed to the sliders 32bF and 32bR. By moving integrally with the sliders 32bF and 32bR, the extension member 33 can be positioned in a standby position (see reference). Figure 5 (solid line in the middle) and the intersection position (refer to) Figure 5 The extension member 33 supports multiple movable wire guides 34 so that they can move back and forth (described in detail later).

[0078] Multiple movable wire guides 34 are respectively provided corresponding to multiple wires Y. Each movable wire guide 34 is configured to temporarily hold the corresponding wire Y during the wire-hanging action. The multiple movable wire guides 34 are supported by an extension member 33. More specifically, the multiple movable wire guides 34 are supported on a support portion 31 via the extension member 33 and two pneumatic shifters 32. Each movable wire guide 34 has a main body 34a and a protrusion 34b. The main body 34a is the part supported by the extension member 33. The protrusion 34b extends from the main body 34a, for example, rearward. Each movable wire guide 34 hooks and holds the corresponding wire Y in the protrusion 34b.

[0079] Multiple movable wire guides 34 are supported on the extension member 33, thereby enabling them to move parallel to the extension member 33 as a unit. Furthermore, the multiple movable wire guides 34 are connected via a wire guide drive unit 107 (see reference 107). Figure 3 The wire guide drive 107 is supported on the extension member 33 and can move back and forth. The wire guide drive 107 includes, for example, a cylinder (not shown). The wire guide drive 107 is configured to position the plurality of movable wire guides 34 at discrete, mutually discrete positions (see reference 107). Figure 7 (a) and the set position in the preceding set (refer to) Figure 7 The multiple movable wire guides 34 can move between (b) and (c). In this way, the multiple movable wire guides 34 can not only move integrally with the extension member 33, but also move relative to the extension member 33 in the front-back direction.

[0080] The wire holding mechanism 28 is a mechanism that receives multiple wires Y from the transfer mechanism 27 and enables them to contact multiple bobbins B respectively. For example... Figure 2 As shown, the thread holding mechanism 28 is, for example, located near the left end of the winding device 13. Figure 5 and Figure 7 As shown in (c), the thread holding mechanism 28 has, for example, a swing shaft 41, two arms 42, an extension member 43, and a plurality of thread holding guides 44 (the thread holding part of the present invention). The two arms 42, the extension member 43, and the plurality of thread holding guides 44 swing together about the swing shaft 41.

[0081] The swing shaft 41 is the axis that serves as the center of the two arms 42, the extension member 43, and the plurality of wire-holding guides 44. The axial direction of the swing shaft 41 extends, for example, in the front-to-back direction. The swing shaft 41 supports the two arms 42 so that they can swing. Each of the two arms 42 is, for example, a generally rod-shaped member. The two arms 42 are arranged in the front-to-back direction. Furthermore, in... Figure 5 Only one of the two arms 42 is shown in the diagram. Each arm 42 is supported, for example, by a swing axis 41. An extension member 43 is mounted at the end (i.e., the front end) of each arm 42 on the side opposite to the swing axis. The extension member 43 is a member that extends in the front-rear direction (see reference). Figure 7(c)). The front end of the extension member 43 is fixed to the front end of the arm portion 42 disposed on the front side. The rear end of the extension member 43 is fixed to the front end of the arm portion 42 disposed on the rear side. A plurality of wire holding guides 44 are fixed to the extension member 43. The plurality of wire holding guides 44 are components fixed to the extension member 43. The plurality of wire holding guides 44 are respectively provided corresponding to the plurality of wires Y. The plurality of wire holding guides 44 are arranged, for example, in a front-back direction (see reference). Figure 7 (c) The multiple thread holding guides 44 are, for example, hook-shaped components. Each thread holding guide 44 has a guide groove 44a. The guide groove 44a is provided to temporarily hold the corresponding thread Y during switching operations. The multiple thread holding guides 44 are capable of swinging (moving) integrally with the arm 42 and the extension member 43.

[0082] The arm 42, the extension member 43, and the wire holding guide 44 are configured to swing integrally about the swing axis 41. These components include, for example, the swing drive 108 (see reference). Figure 3 The present invention uses a oscillating drive unit (the holding drive unit 108) for oscillation. The oscillation drive unit 108 has, for example, a cylinder (not shown) as a drive source. The oscillation drive unit 108 is electrically connected to the control unit 26. When the piston rod (not shown) provided in the cylinder is, for example, fully retracted, multiple wire holding guides 44 are configured to be located... Figure 5 The solid line in the figure indicates the retraction position. In the piston rod, for example, in its fully extended state, the multiple wire retaining guides 44 are configured to be located in... Figure 5 The receiving position is indicated by the double-dotted line.

[0083] The wire-drawing mechanism 29 is configured to temporarily vary the path (wire channel) of multiple wires Y. The wire-drawing mechanism 29 is capable of hooking the wires Y onto the slit SL formed on the outer circumferential surface of the empty tube B (see reference). Figure 8 The action of the wire drawing mechanism 29 is described. The wire drawing mechanism 29 is located near the multiple traversing wire guides 22. Here, only the portion of the wire drawing mechanism 29 corresponding to one wire Y will be described. For example... Figure 8 As shown, the wire drawing mechanism 29 has a track section 51 and a guide member 52. The track section 51 is a member that extends in the front-to-back direction. The track section 51 guides the guide member 52 in the front-to-back direction. The guide member 52 has a capturing section 52a configured to hook and capture the corresponding wire Y. Here, for ease of explanation, the area where the traversing wire guide 22 causes the wire Y to traverse is referred to as the traversing area T (see reference). Figure 8 The guide component 52 is configured to be positioned outside the lateral movement region T, i.e., at the outer position (see reference). Figure 8 The position of the solid line and the inner side of the lateral movement region T is the inner position (refer to the solid line). Figure 8 The guide member 52 is configured to move between the double-dotted lines. Furthermore, the guide member 52 is configured to assume a yarn-feeding posture (see reference). Figure 8 (A single-dot dashed line). The yarn release posture is the posture used to release the yarn Y captured by the capture unit 52a at a position between the outer and inner positions in the front-back direction. The guide member 52 that takes the yarn release posture is slightly tilted rearward compared to the guide member 52 located in the outer position. The yarn pulling mechanism 29 is provided with a number of guide members 52 corresponding to the number of yarns Y. The multiple guide members 52 are driven by the yarn pulling drive unit 109 (see reference). Figure 3 The wire-drawing drive unit 109 includes, for example, a cylinder (not shown) and a cam mechanism (not shown). The cylinder is, for example, a known two-stage cylinder. The cam mechanism is configured to change the position and / or orientation of the guide member 52 according to the extension and retraction of the piston rod (not shown) of the cylinder. One cylinder may simultaneously drive multiple guide members 52. Alternatively, multiple cylinders may be provided corresponding to multiple guide members 52 respectively. The wire-drawing drive unit 109 is electrically connected to the control unit 26.

[0084] The above-described structure is used for hanging wires. Details will be described later.

[0085] (Components related to switching actions)

[0086] Reference Figure 5 , Figures 9-13 The constituent elements related to the switching action are explained. Figure 9 This is a three-dimensional view of the dividing mechanism 60, which will be described later. Figure 10 yes Figure 9 A magnified view of a portion of it. Figure 11 (a) to Figure 13 (b) is a diagram showing the operation of the separating mechanism 60. Figure 11 of (a), Figure 12 (a) and Figure 13 (a) is a front view of the rear end of the dividing mechanism 60. Figure 11 (b) Figure 12 (b) and Figure 13 (b) is a rear view of the rear end of the partition mechanism 60. Figure 11 (a) and Figure 11 (b) indicates the state of the partition mechanism 60 when the partition plate 65 (the partition portion of the present invention) is located in the non-overlapping position described later. Figure 12 (a) and Figure 12 (b) indicates the state of the partition mechanism 60 when the partition plate 65 is located between the non-overlapping position and the partition position described later. Figure 13 (a) and Figure 13 (b) indicates the state of the partition mechanism 60 when the partition plate 65 is in the partition position.

[0087] The spinning traction machine 1, as a component for performing switching operations, includes, for example, a turntable 23 (see reference). Figure 2 ), Thread holding mechanism 28 (refer to) Figure 5 ) and wire drawing mechanism 29 (refer to Figure 8 The turntable 23, the wire holding mechanism 28, and the wire pulling mechanism 29 together constitute the switching unit of the present invention. In this embodiment, the switching unit is a common component used in either the wire hanging or switching operation.

[0088] Additional description is provided for the wire holding mechanism 28 in the turntable 23, the wire holding mechanism 28, and the wire drawing mechanism 29. The multiple wire holding guides 44 of the wire holding mechanism 28 can... Figure 5 The holding position, indicated by the single-dotted line, is temporarily stopped (more precisely, stationary). The holding position is between the retracted position and the receiving position in the circumferential direction of the swing of the plurality of wire holding guides 44. The mechanism that keeps the plurality of wire holding guides 44 stationary in the holding position can be any mechanism. For example, a stop (not shown) capable of rotating integrally with the bobbin support 24 may be provided at a predetermined position on the radially outer side of the bobbin support 24. Furthermore, a contact portion (not shown) capable of contacting the stop may be provided on the extension 43 of the wire holding mechanism 28, for example. In such a configuration, the plurality of wire holding guides 44 can be stopped in the holding position by the contact portion of the swinging mechanism contacting the stop. Alternatively, the stop and contact portion may not be provided. For example, the cylinder (not shown) described above may also have a known two-stage stroke mechanism. As described above, the plurality of wire holding guides 44 are configured to move between the holding position and the retracted position, in addition to being able to move between the retracted position and the receiving position.

[0089] Furthermore, the spinning traction machine 1 is equipped with a separating mechanism 60 (see reference). Figures 9-13 (b)). The separating mechanism 60 is a mechanism for preventing entanglement after the switching operation is completed. The separating mechanism 60 shares a component with the handover mechanism 27. More specifically, the separating mechanism 60 and the handover mechanism 27 share the aforementioned support portion 31 (see [reference]). Figure 9 ).like Figure 10 As shown, the separating mechanism 60 includes, for example, a support portion 31, a cylinder 61 (the separating drive source of the present invention), a rod 62, a first arm portion 63, a second arm portion 64, a separating plate 65, and a cam 66. The rod 62 is oscillated by the cylinder 61, thereby actuating the linkage mechanism having the first arm portion 63, the second arm portion 64, the separating plate 65, and the cam 66. Thus, the separating plate 65 can temporarily separate the space formed between the tube support 24A and the tube support 24B.

[0090] Cylinder 61 is a separation drive unit 110 used to drive the various parts of the separation mechanism 60 (see reference). Figure 3The cylinder 61 is the drive source included in the separation plate 65. In other words, the cylinder 61 is the drive source for moving the separation plate 65. That is, a drive source for moving the multiple movable wire guides 34 and a drive source for moving the separation plate 65 are respectively provided. The separation drive unit 110 is electrically connected to the control unit 26. The cylinder 61 is configured to drive the rod 62 to swing. The cylinder 61 is mounted on the upper end of the support unit 31R. The cylinder 61 has, for example, a cylinder body 61a, a piston rod 61b, and a rod end 61c. The cylinder body 61a is mounted on the support unit 31R in a swingable manner. The cylinder body 61a extends, for example, in a direction slightly inclined relative to the vertical direction. The piston rod 61b is configured to extend and retract relative to the cylinder body 61a. The rod end 61c is provided at the front end of the piston rod 61b. The rod end 61c is connected to the front end of the rod 62.

[0091] The rod 62 is a component that is oscillatingly supported on the support portion 31R. The oscillation axis of the rod 62 is approximately parallel to the front-rear direction. The base end of the rod 62 is fixed to the rear end of the shaft 63a (described later) of the first arm portion 63. The front end of the rod 62 is mounted on the rod end 61c. Furthermore, the rod 62 is oscillating relative to the rod end 61c.

[0092] The first arm 63 is a component that swings integrally with the rod 62. Additionally, the first arm 63 supports the second arm 64, enabling it to swing. The first arm 63 has a shaft 63a (see reference). Figure 10 ) and a pair of arms 63b. In Figure 10 Only arm 63bR, described later, is shown in the diagram. Shaft 63a is a component of the first arm 63 that extends elongatedly in the longitudinal direction. The front end of shaft 63a is rotatably supported in the middle portion of support 31F in the vertical direction. The near portion of the rear end of shaft 63a is rotatably supported in the middle portion of support 31R in the vertical direction. The rear end of shaft 63a is fixed to the base end of rod 62. The pair of arms 63b are, for example, generally plate-shaped long strips. The pair of arms 63b extends in a direction substantially orthogonal to the longitudinal direction. The pair of arms 63b are integrally formed with shaft 63a, for example, by welding. The pair of arms 63b can also be fixed to shaft 63a by fasteners not shown. The pair of arms 63b swings integrally with shaft 63a. The pair of arms 63b are arranged in the longitudinal direction between support 31F and support 31R. One of the pairs of arms 63b is fixed to the rearmost portion of the part supported by the support portion 31F in the shaft 63a (not shown). The other of the pairs of arms 63b ( Figure 10The arm 63bR shown is fixed to the front side of the portion supported by the support portion 31R in the shaft 63a. A pair of arms 63b respectively support the second arm 64 and the partition plate 65, enabling them to swing. A limiting portion 63c is provided on the arm 63bR. The limiting portion 63c limits the swinging of the second arm 64 by contacting the contact portion 64b (described later) of the second arm 64.

[0093] Second arm 64 (refer to) Figure 10 The second arm 64 is a long, roughly plate-shaped component. It swings integrally with the partition plate 65 relative to the first arm 63. The second arm 64 is positioned by a cam 66. The base of the second arm 64 is fixed to the rear end of the partition plate 65. A cam follower 64a is mounted at the front end of the second arm 64. The cam follower 64a is guided along a cam hole 66a formed in the cam 66. A contact portion 64b is provided at the middle of the second arm 64 along its length, configured to contact the limiting portion 63c. The contact portion 64b is positioned opposite the limiting portion 63c in the swing direction of the second arm 64. When the contact portion 64b is not in contact with the limiting portion 63c, the second arm 64 and the partition plate 65 can swing. When the contact portion 64b contacts the limiting portion 63c, the swing of the second arm 64 toward the arm 63bR side is restricted.

[0094] The separator 65 is a generally plate-shaped component used to separate the space formed between the bobbin support 24A and the bobbin support 24B. The separator 65 is formed, for example, from a known sheet metal component. The separator 65 extends relatively long in the front-rear direction. The separator 65 has, for example, a curved portion 65a that is generally arc-shaped when viewed from the front-rear direction and a straight portion 65b that is generally straight when viewed from the front-rear direction. The shape of the separator 65 is not limited to this; it may be curved as a whole or extend in a straight line. Alternatively, a portion of the separator 65 may also be curved. The separator 65 is mounted to a pair of arms 63b in a swingable manner via a swing shaft 65c. A second arm 64 is fixed to the separator 65. The separator 65 is supported on a support portion 31 via a cylinder 61, a rod 62, a first arm 63, and a second arm 64. In other words, the support portion 31 supports the separator 65 in addition to supporting a plurality of movable wire guides 34.

[0095] The cam 66 is a component used to adjust the posture of the swinging second arm 64 and the partition plate 65 to a desired posture. The cam 66 is, for example, a generally flat component. The cam 66 is, for example, fixed to the upper end of the support portion 31R. A cam hole 66a is formed in the cam 66, for example, extending in the front-rear direction. The cam hole 66a extends, for example, in the vertical direction. The cam hole 66a may also be curved in the left-right direction. The cam hole 66a is provided to guide the cam follower 64a. A cam groove (not shown) may also be formed instead of the cam hole 66a.

[0096] A brief explanation of the operation of the separation mechanism 60 with the above configuration will be given. In the fully retracted state of the piston rod 61b of the cylinder 61 (refer to...) Figure 11 (b) The separating mechanism 60 is entirely retracted to the outside of the orbital track of the coil P and the bobbin B (see reference). Figure 11 (a)). The position of the partition plate 65 at this time corresponds to the non-overlapping position of the present invention. When the piston rod 61b begins to extend (refer to...). Figure 12 (b) The first arm 63 swings, and the second arm 64 follows the first arm 63 while its posture is adjusted by the cam 66. Thus, the separator 65 enters the orbital path of the coil P and the bobbin B (see reference). Figure 12 (a)). In the fully extended state of piston rod 61b (refer to...) Figure 13 (b)) When viewed from the front and rear directions, the partition plate 65 is configured to partially surround the multiple upper tubes B (see reference). Figure 13 (a)

[0097] (The order in which the threads are hung)

[0098] Next, the main references are... Figure 14 (a)~ Figure 16 (b) describes the order of thread hanging in the spinning traction machine 1. Figure 14 (a)~ Figure 15 It is a diagram showing the sequence of wire hanging (especially the sequence of wire hanging operations performed by the operator). Figure 16 (a) and Figure 16 (b) is a diagram showing the sequence in which multiple wires Y are transferred from multiple movable wire guides 34 to multiple wire holding guides 44 respectively.

[0099] In the state of the spinning traction machine 1 before the spinning process, multiple filaments Y spun from the spinning device 2 are attracted and held by the suction device 14 (see reference). Figure 4 Furthermore, the second guide roller 12 and the multiple pivot guides 21 are positioned during the wire hanging operation (see reference). Figure 4 The traverse wire guide 22 and the bobbin support 24 stop. The extension part 33 of the transfer mechanism 27 is in the standby position (see reference). Figure 5 (Solid line in the text). The multiple movable wire guides 34 of the transfer mechanism 27 are located in discrete positions (see reference). Figure 7 (a)). The plurality of wire holding guides 44 of the wire holding mechanism 28 are in the retracted position (see reference). Figure 5 (Solid line in the middle). The guide component 52 of the wire drawing mechanism 29 is located on the outer side (see reference). Figure 8 (The solid line in the middle).

[0100] First, such as Figure 14 (a)~ Figure 14 As shown in (c), the operator hangs the yarn onto the first guide roller 11, the second guide roller 12, and the multiple fulcrum guides 21. Specifically, the operator operates a known suction gun 70 capable of attracting and holding the yarn Y to pull the multiple yarns Y attracted and held by the suction device 14. Then, the operator hooks the multiple yarns Y attracted and held by the suction gun 70 onto the first guide roller 11 and the second guide roller 12 in that order (see Figure 1). Figure 14 (a) and Figure 14 (b)). Furthermore, the operator uses a wire-hanging clamp (not shown) to hook multiple wires Y onto multiple fulcrum wire guides 21 (see reference). Figure 14 (c) Afterwards, the operator performs an operation to cause the winding device 13 to engage the wire. More specifically, the operator, for example, presses a first operation button (not shown) that is electrically connected to the control unit 26.

[0101] When the first operation button is pressed, the control unit 26 initiates the yarn-coating action of each part of the take-up device 13. First, the control unit 26 controls the roller movement motor 101 (see reference...) Figure 3 ) and the wire guide drive unit 105 (see reference) Figure 3 This causes the second guide roller 12 and the fulcrum guide 21 to move to the position during the winding operation (see reference). Figure 15 Additionally, the control unit 26 controls the guide wire drive unit 107 (see reference). Figure 3 This moves multiple movable wire guides 34 to the assembly position (see reference). Figure 7 (b)). Next, the operator operates the suction gun 70 to hook the yarn Y hook onto the yarn convergence guide 71 located at the front end of the right end of the winding device 13 (see reference). Figure 15 Therefore, multiple wires Y are respectively positioned immediately behind the corresponding movable wire guide 34 (see reference). Figure 7 (b)). Then, the operator presses a second operation button (not shown) that is electrically connected to the control unit 26.

[0102] When the second operation button is pressed, the control unit 26 controls the swing drive unit 108 (see reference). Figure 3 This causes the multiple wire holding guides 44 of the wire holding mechanism 28 to move from the retracted position (see reference). Figure 5 The solid line) swings to the receiving position (refer to...) Figure 5 (The double-dotted line). Thus, multiple wire holding guides 44 move to the vicinity of the transfer mechanism 27. Furthermore, the control unit 26 appropriately controls the turntable motor 103 during the wire hanging operation, positioning the bobbin support 24 in a position that does not interfere with the wire holding mechanism 28. In parallel with the timing of the oscillation of the wire holding guides 44, the control unit 26 controls the wire guide drive unit 107 (see reference). Figure 3 This causes the multiple movable wire guides 34 of the transfer mechanism 27 to move from the assembly position (see reference). Figure 7 (b)) To discrete positions (refer to) Figure 7 (a)) movement. Thus, the yarn Y is temporarily hooked onto each movable yarn guide 34. The protrusion 34b prevents the yarn Y from falling off each movable yarn guide 34. Together with the control of the yarn guide drive unit 107, the control unit 26 controls, for example, the take-up motor 104A (see reference). Figure 3 This causes the bobbin support 24A to begin rotating. Simultaneously with the start of rotation of the bobbin support 24A, the control unit 26 controls the traverse motor 102, causing the traverse wire guide 22 to begin operating.

[0103] Next, the control unit 26 performs the transfer of the yarn Y from the transfer mechanism 27 to the yarn holding mechanism 28. Specifically, the control unit 26 controls the movement drive unit 106 to move the plurality of movable yarn guides 34 of the transfer mechanism 27 from the standby position (see reference). Figure 5 Move the solid line in the middle to the intersection position (refer to the solid line in the middle). Figure 5 (The double-dotted line in the text). As a result, multiple threads Y move to the vicinity of their respective thread-holding guides 44 (see reference). Figure 16 (a)). Next, the control unit 26 controls the guide wire drive unit 107 (see reference 107). Figure 3 This causes the multiple movable wire guides 34 of the transfer mechanism 27 to move from discrete positions (see reference). Figure 7 (a) is moved again to the set position (refer to) Figure 7 (b)). Thus, each wire Y is transferred from the corresponding movable wire guide 34 to the corresponding wire holding guide 44 (see reference). Figure 16 (b) Specifically, each thread Y falls into the inclined portion of the corresponding thread holding guide 44 and enters the guide groove 44a. In this way, each thread holding guide 44 is configured to temporarily hold the thread Y during the thread hanging operation.

[0104] Next, the control unit 26 controls the swing drive unit 108 to swing the wire holding guide 44 of the wire holding mechanism 28 from the receiving position to the left. As a result, the wire Y is captured and traversed by the traversing wire guide 22.

[0105] Next, the control unit 26 causes the wire-drawing mechanism 29 to thread the wire onto the bobbin B1. Specifically, the control unit 26 controls the turntable motor 103 to move the rotating bobbin support 24A upward. Furthermore, the control unit 26 controls the wire-drawing drive unit 109 to move the plurality of guide members 52 from their outer positions (see reference 1). Figure 8 (The solid line) towards the inside (refer to) Figure 8 The double-dotted line moves. The multiple transversely moving threads Y are captured by the capturing part 52a of the corresponding guide member 52. At this time, each thread Y is located near the slit SL of the corresponding tube B2 in the axial direction.

[0106] Furthermore, the control unit 26 controls the wire drawing drive unit 109 to move the plurality of guide members 52 from the inner position to the outer position (see reference). Figure 8 (The solid lines). Thus, each thread Y temporarily detaches from the transverse guide 22 and hooks onto the corresponding slit SL of the bobbin B1 (refer to...). Figure 8 (Double-dotted line). A claw (not shown) is formed in the slit SL. Thread Y is hooked onto the claw and wound around the slit SL. This applies a strong tension to thread Y, causing the portion of thread Y located between the bobbin B1 and the suction gun 70 in the direction of travel to break. The portions of the broken threads Y on the suction gun 70 side are then attracted and removed by the suction gun 70. As described above, the thread-hanging action is completed, and the winding action begins.

[0107] (Switch action)

[0108] Next, refer to Figure 17 (a)~ Figure 17 (d) explains the switching action of the spinning traction machine 1. Figure 17 (a)~ Figure 17 (c) is a diagram representing the switching action. Figure 17 (d) is a diagram showing the state of the separation mechanism 60 after the switching action is completed.

[0109] In the state of the spinning traction machine 1 before the switching operation, multiple filaments Y are wound onto multiple bobbins B1 to form multiple packages P (refer to...). Figure 17 (a)). When viewed from the front, the roll P rotates counterclockwise, for example (see reference). Figure 17 (arrow (a)). Multiple thread holding guides 44 are in the retracted position. Separator 65 is in the non-overlapping position. When viewed from the front and rear directions, the separator 65 in the non-overlapping position does not overlap with the travel track (thread channel) of the thread Y held by the thread holding guides 44 in the holding position during the switching operation.

[0110] When the control unit 26 determines that multiple rolls P are full, it causes each unit to begin the following switching operation. First, the control unit 26 controls the turntable motor 103 to rotate the turntable 23 (see reference). Figure 17 (See arrow in (b)). At this time, the yarn Y is connected to the package P and also in contact with the bobbin B2. The control unit 26 controls the take-up motor 104B at an appropriate timing, causing the bobbin support 24B to start rotating. When viewed from the front, the bobbin B2 rotates counterclockwise, for example (illustration omitted). In addition, the yarn Y is maintained in a state of being traversed by the traversing guide 22.

[0111] Next, the control unit 26 controls the swing drive unit 108 to move the plurality of wire holding guides 44 from the retracted position to the holding position (see reference). Figure 17(c) Thus, each wire holding guide 44 is pressed against the corresponding wire Y. The traversing wire Y falls into the inclined portion of the corresponding wire holding guide 44 and enters the guide groove 44a. Thus, each wire Y is held by the respective wire holding guide 44.

[0112] Next, the control unit 26 controls the wire drawing drive unit 109 (see reference). Figure 3 This causes the multiple guide components 52 of the wire drawing mechanism 29 to move from their outer positions (see reference). Figure 8 (The solid line) towards the inside (refer to) Figure 8 The double-dotted line moves. The traversing wire Y is captured by the capturing part 52a of the corresponding guide member 52. Furthermore, the control unit 26 controls the wire drawing drive unit 109 to move the plurality of guide members 52 from the inner position to the outer position (see reference). Figure 8 (Solid lines). Thus, each thread Y temporarily detaches from its corresponding transverse guide 22 and hooks onto the slit SL of its corresponding bobbin B2 (see reference). Figure 8 (The double-dotted line). The thread Y is hooked onto the aforementioned claw (not shown), and is wound into the slit SL. At this time, a strong tension is applied to the thread Y located between the roll P and the bobbin B2, causing the thread Y to break between the roll P and the bobbin B2. That is, the switching unit is configured such that, during the switching operation, the thread Y is broken by applying tension to the thread Y traveling towards the roll P via the bobbin B2.

[0113] As described above, multiple yarns Y can be transferred from multiple rolls P to multiple bobbins B2 respectively, and the multiple yarns Y can be wound onto multiple bobbins B2 respectively. The operation of the spinning traction machine 1 as described above (further limited to the operation of the winding device 13) is the switching operation in this embodiment.

[0114] When the switching action is completed, the control unit 26 controls the partition drive unit 110 to move the partition plate 65 to the partition position (see reference). Figure 17 (d)). The timing for the completion of the switching action could be, for example, when a predetermined time has elapsed since the control unit 26 moved the guide member 52 from the inner position to the outer position. Additionally, at the timing for the completion of the switching action, the control unit 26 moves the plurality of wire holding guides 44 from the holding position to the retracted position (see [reference]). Figure 17 (d)). The retreat position is the position of the partition plate 65 that is farther away from the separation position compared to the holding position. More precisely, the control unit 26 preferably controls the separation drive unit 110 to position the partition plate 65 in the separation position after the switching action is completed, and controls the swing drive unit 108 to move the plurality of wire holding guides 44 from the holding position toward the retreat position before the partition plate 65 reaches the separation position.

[0115] After the switching action, the control unit 26 controls the wire-drawing drive unit 109 to cause the multiple guide components 52 to respectively adopt the wire-disengagement posture (see reference). Figure 8 (The single-dot dashed line). Thus, each yarn Y is captured by the corresponding traverse guide 22, and traverse movement begins again (i.e., the winding of yarn Y towards the bobbin B2 begins). In addition, the control unit 26 controls the winding motor 104A to stop the rotation of the bobbin support 24A. After that, multiple rolls P are retrieved.

[0116] Imagine the state of the winding device 13 when the switching operation is completed, multiple rolls P are held by the bobbin support 24A, and the separator plate 65 is in the separating position. Hereinafter, for ease of explanation, this state will be referred to as the completed state. When a predetermined time has elapsed since the separator plate 65 was moved to the separating position (i.e., after the completed state has been maintained for a predetermined time), the control unit 26 moves the separator plate 65 from the separating position to a non-overlapping position (not shown). This avoids interference between the separator plate 65 and the multiple rolls P formed by winding the yarn Y onto the multiple bobbins B2.

[0117] (Detailed information regarding the configuration of each component)

[0118] Next, details related to the configuration of the components in the winding device 13 will be explained. More specifically, the positional relationship between the multiple wire holding guides 44 and the separator 65, as well as the positional relationship between the completed winding P and the bobbin B2 and the separator 65, will be explained.

[0119] Divider 65 when in the dividing position (refer to) Figure 18 The solid line) is arranged in the radial direction of the bobbin B2 (i.e., the radial direction of the bobbin support 24B), in a configuration that holds multiple wire holding guides 44 (refer to) when holding multiple wires Y respectively during the switching operation. Figure 18 The double-dotted line) is located away from the position of the tube support 24B (and multiple tubes B2).

[0120] During the switching operation, multiple wire holding guides 44 are positioned between the bobbin B2 and the coil P in the direction of wire Y travel (see reference). Figure 17 (c)). Furthermore, during the switching operation, the multiple wire holding guides 44 are configured to bend the wire channel through which the wire Y travels. Also, during the switching operation, the multiple wire holding guides 44 are located radially on the bobbin support 24B at a position close to the bobbin support 24B (and the bobbin B2) by a track that is closer to the bobbin support 24B (and the bobbin B2) than the track on which the partition plate 65 moves (see reference). Figure 18 ).

[0121] Imagine the completed state. For example... Figure 18As shown, a first imaginary line segment VLS1 is defined that connects the rotation axis center (point P1) of the bobbin support 24A to the rotation axis center (point P2) of the bobbin support 24B when viewed from the front-rear direction. The direction in which the first imaginary line segment VLS1 extends is defined as the extension direction. Furthermore, two imaginary tangent lines (first imaginary tangent line VLT1 and second imaginary tangent line VLT2) are defined that are parallel to the first imaginary line segment VLS1 and tangent to the outer periphery of the bobbin support 24B. When viewed from the front-rear direction, the partition plate 65 extends transversely through both the first imaginary tangent line VLT1 and the second imaginary tangent line VLT2, and remains separate from the guide members 44 of the multiple threads. Additionally, two imaginary tangent lines (third imaginary tangent line VLT3 and fourth imaginary tangent line VLT4) are defined that are parallel to the first imaginary line segment VLS1 and tangent to the outer periphery of the bobbin B2. When viewed from the front and rear directions, the partition 65 extends in a manner that crosses both the third imaginary tangent VLT3 and the fourth imaginary tangent VLT4.

[0122] In the completed state, the partition plate 65 is configured to surround the tube support 24B (and the plurality of tubes B2) at an angle of 90 degrees or more throughout the circumference of the tube support 24B. More specifically, a second imaginary line segment VLS2 is defined, connecting point P2 to the end of the partition plate 65 that is closer to the first imaginary tangent VLT1 than the first imaginary line segment VLS1 (see reference). Figure 18 Furthermore, the term "end" here refers to the end of the portion of the partition plate 65 that surrounds the plurality of tubes B2 circumferentially, and does not necessarily mean the base end (or front end) of the swinging part of the partition plate 65. Additionally, a third imaginary line segment VLS3 is defined, connecting point P2 to the end of the partition plate 65 that is closer to the second imaginary tangent VLT2 than the first imaginary line segment VLS1 (see [reference]). Figure 18 The angle range defined by the second imaginary line segment VLS2 and the third imaginary line segment VLS3 is the aforementioned angle range. More specifically, the angle formed by the first imaginary line segment VLS1 and the second imaginary line segment VLS2 is defined as the first angle θ1. The angle formed by the first imaginary line segment VLS1 and the third imaginary line segment VLS3 is defined as the second angle θ2. The sum of the first angle θ1 and the second angle θ2 is 90 degrees or more. Furthermore, the partition plate 65 is configured to cover the entire area in the front-back direction of the plurality of cylinders B2 within the aforementioned angle range.

[0123] Furthermore, the direction of rotation of multiple rolls P is defined as the roll rotation direction. In the completed state, the roll rotation direction is the direction in which the portion of roll P located on the first imaginary line segment VLS1 moves from the side of the first imaginary tangent VLT1 to the side of the second imaginary tangent VLT2 (refer to...). Figure 18 (The arrow). In this case, in this embodiment, the first angle θ1 is greater than the second angle θ2.

[0124] By configuring the aforementioned separator 65, it is possible to prevent the end (thread head Ye) of the filament Y of the rotating coil P from getting caught in the rotating bobbin B2. More specifically, Figure 18 The thread end Ye, shown by the solid line, is prevented from moving towards the bobbin B2 by the separator plate 65. Figure 18 The thread end Ye, indicated by a double-dotted line, generates accompanying flow through the rotation of the bobbin B2 (see reference). Figure 18 (As shown by the arrow) to prevent movement toward the B2 side of the tube.

[0125] As described above, when viewed from the front and rear directions, the separator 65 extends across both sides of the two imaginary tangents (the first imaginary tangent VLT1 and the second imaginary tangent VLT2) and is separated from the multiple thread guides 44. This allows the separator 65 to avoid interference with the thread guides 44 and to significantly block the area where the bobbin B2 is particularly close to the package P. Therefore, the possibility of the thread end Ye on the package P side at the end of its formation being wound into the empty bobbin B side (bobbin B2 side) can be reduced.

[0126] Furthermore, the wire holding guide 44 is movable between a holding position and a retracted position. Therefore, by moving the wire holding guide 44 to the retracted position after the switching action is completed, interference between the partition plate 65 and the wire holding guide 44 can be more reliably avoided.

[0127] Furthermore, the control unit 26 controls the separation drive unit 110 to position the separator plate 65 in the separation position after the switching operation is completed, and controls the swing drive unit 108 to move the plurality of wire holding guides 44 from the holding position toward the retracted position before the separator plate 65 reaches the separation position. This reliably prevents interference between the separator plate 65 and the wire holding guides 44 after the switching operation is completed.

[0128] Furthermore, the separator 65 is configured to surround the bobbin holder 24B at an angle of 90 degrees or more throughout its circumference when in the separated position. This allows the bobbin holder 24B to surround multiple bobbins B2 over a large area throughout its circumference. Therefore, the possibility of the yarn end Ye on the P-side of the coil being wound into the bobbin B2 side can be further effectively reduced.

[0129] Furthermore, the first angle θ1 is larger than the second angle θ2. Thus, the separator 65 is configured to extend longer toward the first imaginary tangent VLT1 side. Therefore, the separator 65 can effectively prevent the longer extended thread end Ye from being wound into the bobbin B2 side.

[0130] Furthermore, when in the separated position, the partition plate 65 is positioned radially away from the bobbin support 24B than the multiple wire holding guides 44 when holding multiple wires Y during the switching operation. Thus, the partition plate 65 in the separated position is positioned radially away from the bobbin support 24B. Therefore, the partition plate 65 can remain in the separated position for an extended period.

[0131] Furthermore, during the switching operation, the wire holding guide 44 is positioned between the bobbin B2 and the coil P in the direction of wire Y's travel, and is configured to bend the wire channel through which wire Y travels. Also, during the switching operation, the wire holding guide 44 is located radially closer to the bobbin support 24B than the track on which the separator plate 65 moves. Thus, during the switching operation, the wire holding guide 44 is positioned close to the bobbin support 24B. Therefore, the wire end on the bobbin B2 side of the disconnected wire Y can be shortened.

[0132] Furthermore, the wire holding guide 44 temporarily holds the wire Y during the wire hanging operation. That is, the wire holding guide 44 can be used not only for the switching operation but also for the wire hanging operation. Therefore, both the switching operation and the wire hanging operation can be performed with a relatively small number of components.

[0133] In addition, the support portion 31 supports not only the multiple movable wire guides 34, but also the partition plate 65. Therefore, compared with the configuration where the multiple movable wire guides 34 and the partition plate 65 are supported by different components, the increase in the number of components can be suppressed.

[0134] In addition, drive sources are provided for moving and driving the plurality of movable wire guides 34 and for moving and driving the partition plate 65. The plurality of movable wire guides 34 are configured to move in parallel, and the partition plate 65 is configured to swing. If a single drive source were used to achieve the parallel movement of the plurality of movable wire guides 34 and the swinging movement of the partition plate 65, a complex mechanism would be required. In this embodiment, the plurality of movable wire guides 34 and the partition plate 65 are moved and driven by different drive sources, thus suppressing the complexity of the mechanism.

[0135] Furthermore, the spinning traction machine 1 is equipped with a turntable 23. Therefore, the positions of the bobbin support 24A and the bobbin support 24B can be easily changed using the known turntable 23.

[0136] Furthermore, when viewed from the front and rear directions, the separator 65 extends across both the third imaginary tangent VLT3 and the fourth imaginary tangent VLT4. This ensures that the separator 65 does not interfere with the thread guide 44, and that the separator 65 can cover a wider area where the bobbin B2 is particularly close to the coil P. Therefore, the possibility of the thread end Ye on the coil P side at the end of its formation being wound into the empty bobbin B side (bobbin B2 side) can be further reduced.

[0137] Next, variations of the described embodiment will be described. Components having the same configuration as those in the described embodiment will be labeled with the same reference numerals, and their descriptions will be omitted as appropriate.

[0138] (1) In the embodiment described above, the partition plate 65, when in the partitioned position, is arranged to surround a plurality of tubes B2 at an angle range of 90 degrees or more throughout the circumference of the tube support 24B. However, this is not a limitation. The aforementioned angle range may also be less than 90 degrees.

[0139] (2) In the embodiments described above, the first angle θ1 is larger than the second angle θ2. However, this is not a limitation. The first angle θ1 may also be less than or equal to the second angle θ2.

[0140] (3) In the embodiments described above, a pneumatic shifter 32 for moving and driving the plurality of movable wire guides 34 and a cylinder 61 for moving and driving the partition plate 65 are respectively provided. However, this is not a limitation. The drive source for moving and driving the plurality of movable wire guides 34 and the drive source for moving and driving the partition plate 65 may also be the same. However, in this case, a complex mechanism may be required to make the plurality of movable wire guides 34 move in parallel and the partition plate 65 swing.

[0141] (4) In the embodiments described above, the plurality of movable wire guides 34 are configured to move in parallel, and the partition plate 65 is configured to swing. However, this is not a limitation. The plurality of movable wire guides 34 may also be configured to swing. The partition plate 65 may also be configured to move in parallel.

[0142] (5) In the embodiments described above, the support portion 31 supports both the plurality of movable wire guides 34 and the partition plate 65. However, it is not limited to this. The support portion 31 may also support only one of the plurality of movable wire guides 34 and the partition plate 65. The other of the plurality of movable wire guides 34 and the partition plate 65 may also be supported by a different component (not shown) than the support portion 31.

[0143] (6) In the embodiments described above, the plurality of wire holding guides 44 can be used not only for switching operations but also for wire hanging operations. However, this is not a limitation. The plurality of wire holding guides 44 may also be used only during switching operations. In this case, a plurality of wire guides (not shown) for wire hanging operations may be provided instead of the plurality of wire holding guides 44.

[0144] (7) In the embodiments described above, during the switching operation, the plurality of wire holding guides 44 are located radially closer to the bobbin support 24B than the track on which the separator plate 65 moves. In other words, when in the separated position, the separator plate 65 is positioned radially away from the bobbin support 24B than the plurality of wire holding guides 44 are during the switching operation. However, this is not a limitation. The positional relationship between the plurality of wire holding guides 44 and the separator plate 65 can also be reversed. Alternatively, the tracks of the plurality of wire holding guides 44 and the track of the separator plate 65 can partially overlap. However, in the case of these partial track overlaps, the control unit 26 needs to control the swing drive unit 108 after the switching operation is completed so that the wire holding guides 44 move away from the holding position.

[0145] (8) In the embodiments described above, after the switching operation is completed, the control unit 26 controls the separating drive unit 110 to move the separating plate 65 to the separating position, and controls the swing drive unit 108 to move the wire holding guide 44 to the retracting position. However, this is not a limitation. If the tracks of the multiple wire holding guides 44 do not overlap with the tracks of the separating plate 65, the control unit 26 may also move the wire holding guide 44 to the retracting position after the separating plate 65 reaches the separating position.

[0146] (9) In the embodiments described above, the plurality of wire holding guides 44 are movable between a holding position and a retracted position. However, this is not a limitation. The plurality of wire holding guides 44 may, for example, be fixed relative to the turntable 23. However, in this case, a mechanism is required for transferring each wire Y to each wire holding guide 44 during the switching operation. In addition, in order to avoid interference between the roll P and the wire holding guide 44, the size of the roll P that can be formed may be significantly limited.

[0147] (10) In the embodiments described above, the thread holding guide 44 is provided on the thread holding mechanism 28. However, it is not limited thereto. The drive mechanism (not shown) that drives the thread holding guide 44 to move may also be provided on the transfer mechanism 27 or the separation mechanism 60, for example.

[0148] (11) In the embodiments described above, the separator 65 is disposed on the separator mechanism 60. However, it is not limited thereto. The drive mechanism (not shown) that drives the separator 65 to move may also be disposed on the wire holding mechanism 28, for example.

[0149] (12) In the embodiments described above, when viewed from the front-rear direction, the partition plate 65 extends in a manner that crosses both the third imaginary tangent VLT3 and the fourth imaginary tangent VLT4. However, it is not limited to this. The partition plate 65 may extend in a manner that crosses both the first imaginary tangent VLT1 and the second imaginary tangent VLT2, or it may not cross both the third imaginary tangent VLT3 and the fourth imaginary tangent VLT4.

[0150] (13) In the embodiments described above, the winding device 13 has a turntable 23. However, it is not limited to this. Other mechanisms for changing the position of the bobbin support 24A and the bobbin support 24B may be provided instead of the turntable 23.

[0151] (14) In the embodiments described above, the spinning traction machine 1 is configured to wind up multiple filaments Y. However, it is not limited to this. The spinning traction machine 1 may also be configured to wind up only one filament Y.
