Description

Technical Field

[0001] This utility model relates to a wire winding device for winding up filaments. Background Technology

[0002] Patent Document 1 discloses a yarn winding device for winding multiple yarns spun from a spinning device onto multiple bobbins mounted on a bobbin holder to form multiple packages. The multiple yarns spun from the spinning device are held in a state by being attracted by a suction gun operated by an operator and hung on a slit formed at the end of each bobbin, thereby being wound onto each bobbin.

[0003] Here, when the tension of the thread is too high, the thread is pulled into the slit under strong tension. This can cause thread breakage when a load is applied to the thread through contact with components related to the thread-hanging action (including the slit). On the other hand, if the tension of the thread in the slit is too low, the thread may become loose and entangled in other components, resulting in breakage. Therefore, tension gauges have traditionally been used to measure the tension of the thread held by the suction gun. The operator adjusts the suction pressure of the suction gun while referring to the tension gauge readings, thereby appropriately adjusting the tension of the thread in the slit. Known tension gauges include handheld types operated by the operator and fixed types positioned at a designated location.

[0007] However, when using a handheld tension meter, the operator needs to temporarily place the suction gun on a fixed platform before operating the tension meter. This is because the suction gun is a relatively heavy component, and it is difficult for the operator to support it with only one hand while operating the tension meter. Furthermore, when using a fixed tension meter, the measured value is usually displayed on a control monitor located in a separate area from the operator's workspace. Therefore, after placing the suction gun on the fixed platform, the operator needs to go to the control monitor to confirm the tension value. As mentioned above, the operator needs to temporarily place the suction gun on a fixed platform to confirm the tension value of the thread held by the suction gun, resulting in time consumption. In addition, while the operator is confirming the thread tension value, the thread continues to be attracted by the suction gun placed on the fixed platform. Since these threads are discarded, thread loss occurs. This problem is particularly pronounced the lower the tension of the thread held by the suction gun. That is, the lower the tension of the thread, the more accurately the tension of the thread needs to be controlled, and correspondingly, the time required for the operation also increases.

[0008] The purpose of this invention is to enable the operator to easily control the tension of the thread held by the suction gun when hanging the thread onto the bobbin.

[0009] The present invention provides a yarn winding device comprising: a bobbin support, wherein a plurality of bobbins are arranged and mounted on the bobbin support along a predetermined axial direction; a traversing device for traversing a plurality of yarns wound onto the plurality of bobbins; a contact roller extending along the axial direction and applying contact pressure to the winding, the winding being formed by the plurality of yarns being wound onto the plurality of bobbins mounted on the bobbin support; a support member extending along the axial direction and supporting the traversing device and the contact roller; a machine base cantilevered along the axial direction supporting the base end of the bobbin support and the base end of the support member; a tension meter for measuring the tension of the yarns attached to at least one of the plurality of bobbins; and a display unit displaying the tension value of the yarns measured by the tension meter, the display unit being positioned in a location visible to an operator operating a suction gun for yarn loading onto the plurality of bobbins.

[0010] According to this solution, the display unit showing the tension value of the thread attached to the bobbin is positioned within the visual range of the operator who operates the suction gun to perform thread-attaching operations on multiple bobbins. Therefore, the operator can easily control the thread tension by observing the tension value displayed on the display unit while operating the suction gun. This solution is particularly effective when the tension of the thread held by the suction gun is low and accurate tension control is crucial.

[0011] In the thread winding device of this utility model, preferably, the display part is mounted on the top end of the support member in the axial direction, and the top end is located on the opposite side of the base end of the support member supported by the machine platform.

[0012] Generally, the thread tensioning operation using a suction gun begins from the top of the axially oriented support member. According to this design, a display unit is installed at the top of the support member, easily visible to the operator of the suction gun. Therefore, the operator can more easily monitor the thread tension.

[0013] In the thread winding device of this utility model, preferably, the support member has a cover on the top end in the axial direction, and the display part is mounted on the cover.

[0014] According to this design, the display unit is mounted in a cover that is easily visible to the operator operating the suction gun. Therefore, the operator can more easily monitor the tension of the yarn.

[0015] In the thread winding device of this utility model, preferably, the display part is mounted on the top surface of the cover in the axial direction.

[0016] The operator of the suction gun faces the top surface of the cover during operation. According to this design, since the display unit is mounted on the axially aligned top surface of the cover, the operator can easily visually identify the suction gun. Therefore, the operator can more easily control the tension of the yarn. It should be noted that the top surface of the cover is the axially aligned top-side surface of the cover.

[0017] In the yarn winding device of this utility model, preferably, the tension meter is fixedly disposed on the upstream side of the bobbin support in the yarn traveling direction.

[0018] According to this solution, since the tension gauge is fixed on the upstream side of the bobbin support, the operator does not need to operate the tension gauge, making wire hanging operations easy. Furthermore, because there is ample space upstream of the bobbin support in the wire travel direction, it is easy to install the tension gauge.

[0019] Preferably, the yarn winding device of this utility model has multiple transverse fulcrum guides, which are arranged corresponding to multiple yarns wound on the multiple bobbins. The tension meter is arranged on the upstream side of one of the multiple transverse fulcrum guides in the yarn traveling direction.

[0020] In this design, a tension meter is positioned upstream of one of the multiple traverse guide points in the direction of yarn travel, and the tension of one of the multiple yarns is measured as a representative value. This eliminates the need for multiple tension meters corresponding to each yarn, simplifying the structure of the yarn winding device. Attached Figure Description

[0051] (Spinning traction machine)

[0052] Reference Figure 1 as well as Figure 2 The spinning traction machine 1 of this embodiment is described. Figure 1 This is a side view of the spinning traction machine 1. Figure 2 This is a front view of the spinning traction machine 1. It should be noted that... Figure 2 The description of the front cover 72, which will be discussed later, is omitted.

[0053] The spinning traction machine 1 is configured to draw multiple filaments Y spun from the spinning device 2 and wind them onto multiple bobbins B to form multiple packages P. The spinning device 2 discharges, for example, molten polymers that are the material of the filaments Y. The material of the filaments Y is, for example, polyester materials such as PET, but is not limited thereto. The filaments Y are, for example, monofilaments composed of a single filament, but are not limited thereto.

[0054] like Figure 1 and Figure 2 As shown, the spinning traction machine 1 includes a first guide roller 11, a second guide roller 12, and a yarn winding device 13.

[0055] The first guide roller 11 is a roller whose axial direction is approximately parallel to the left-right direction. The first guide roller 11 is, for example, positioned below the spinning apparatus 2. Multiple yarns Y are wound onto the first guide roller 11 in a left-right direction. The first guide roller 11 is driven to rotate by a motor (not shown). Thus, the first guide roller 11 conveys the multiple yarns Y downstream in the yarn travel direction.

[0056] The second guide roller 12 is a roller whose axial direction is approximately parallel to the left-right direction. The second guide roller 12 is positioned downstream of the first guide roller 11 in the yarn travel direction. The second guide roller 12 is positioned 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 the yarn Y downstream in the yarn travel direction.

[0057] The thread winding device 13 is configured to perform a winding operation that winds multiple threads Y onto multiple bobbins B to form multiple packages P. The thread winding device 13 is positioned downstream of the second guide roller 12 in the thread travel direction. The thread winding device 13 is positioned below the second guide roller 12.

[0058] (Structure of the thread winding device)

[0059] Reference Figures 1 to 7 Explain the structure of the thread winding device 13. Figure 3 This is a schematic top view showing the lateral movement device 30 and its surrounding parts, which will be described later. Figure 4 This is a schematic side view showing the traversing device 30 and its surrounding area. Figure 5 This is a block diagram showing the electrical structure of the wire winding device 13. Figure 6 This is a front view of a pair of winding units 14 viewed from the front. Figure 7 This is a 3D view of the left-side winding unit 14. It should be noted that... Figure 7 The descriptions of the transverse movement device 30 (described later), the thread temporary guide 27 (described later), the first thread guide 28 (described later), and the second thread guide 29 (described later) are omitted.

[0060] The thread winding device 13 includes a pair of winding units 14 (see reference). Figure 6 ) and control unit 26 (refer to Figure 2 A pair of take-up units 14 are arranged facing each other in the left-right direction. The yarn take-up device 13 of this embodiment is configured, for example, to take up multiple yarns Y (e.g., 12 yarns) spun from the spinning device 2 through a pair of take-up units 14, wherein each take-up unit takes up half (e.g., 6 yarns). Figure 1 as well as Figure 2 In this diagram, only the left winding unit 14A is shown, while the right winding unit 14B is omitted. The structural elements of the left winding unit 14A and the right winding unit 14B are arranged symmetrically to each other. Hereinafter, the structural elements of the left winding unit 14A will be described, representing a pair of winding units 14. Figure 1 as well as Figure 2 As shown, the winding unit 14A includes: a machine base 20, multiple fulcrum guides 21 (the transverse fulcrum guides of this utility model), multiple transverse guides 22, a turntable 23, two bobbin supports 24, a contact roller 25, a support component 40 (the support component of this utility model), a yarn temporary storage guide 27, a first yarn hanging guide 28, and a second yarn hanging guide 29.

[0061] The machine base 20 is a component erected vertically. For example, the machine base 20 is located at the rear end of the winding unit 14A. The machine base 20 cantilever supports the rear end of the bobbin support 24 (the base end of the bobbin support in the axial direction of this invention) and the rear end of the support member 40 (the base end of the support member 40 in the axial direction of this invention). Multiple pivot guides 21 are guides that serve as pivots for the yarn Y when it is traversed by each traversing guide 22. Each pivot guide 21 guides the yarn Y downstream in the yarn travel direction. Figure 1 As shown, multiple pivot wire guides 21 are individually configured for multiple wires Y. The multiple pivot wire guides 21 are arranged in the front-to-back direction.

[0062] Multiple traverse guides 22 are individually provided for multiple yarns Y. The multiple traverse guides 22 are arranged in a front-to-back direction. The multiple traverse guides 22 are used to wind the yarn onto the upper bobbin support 24 (see, for example, reference...). Figure 1 (Details to follow) A component that traverses multiple wires Y on multiple bobbins B. Each traverse guide 22 is, for example, a traverse motor 31 (see...) Figure 3 as well as Figure 5 Driven by the axial force, the wire Y moves back and forth at least in the front-to-back direction. As a result, the wire Y hanging on the lateral guide 22 is laterally moved with the fulcrum guide 21 as the center.

[0063] More specifically, the plurality of traverse guides 22 are, for example, respectively included in a plurality of traverse devices 30 (see reference). Figure 3 Multiple traverse mechanisms 30 are arranged in a front-to-back direction. The traverse mechanisms 30 adjacent to each other in the front-to-back direction are as follows: Figure 3 As shown, they can be configured to partially overlap in the front-to-back direction. Each traverse device 30 includes, for example, the aforementioned traverse motor 31, drive pulley 32, two driven pulleys 33, and an annular belt 34. It should be noted that these components are mounted, for example, on a plate-shaped base component included in the traverse device 30. To avoid complicating the drawings, the base component is omitted from the illustration.

[0064] The traverse motor 31 is, for example, a servo motor with a rotary encoder (not shown). The rotation angle of the rotating shaft of the traverse motor 31 is detected by the rotary encoder. Thus, the position of the traverse guide 22 in the front-to-back direction can be calculated, for example, based on a prescribed formula.

[0065] The drive pulley 32 is the pulley wound around the annular belt 34. The drive pulley 32 is driven to rotate in the forward and reverse directions by the traverse motor 31.

[0066] Similar to the drive pulley 32, the two driven pulleys 33 are wound around the annular belt 34. The two driven pulleys 33 rotate driven by the movement of the annular belt 34. The rotation axis of each driven pulley 33 is approximately parallel to the rotation axis of the drive pulley 32. Figure 3 As shown, the two driven pulleys 33 have a driven pulley 33a arranged on the front side and a driven pulley 33b arranged on the rear side. The line segment (not shown) connecting the rotation axis center of the driven pulley 33a and the rotation axis center of the driven pulley 33b can be inclined relative to the front-back direction. The driven pulley 33b of a certain traverse device 30 and the driven pulley 33a of the traverse device 30 arranged on the rear side of the traverse device 30 can, for example, be arranged at a position that at least partially overlaps in the front-back direction.

[0067] An annular belt 34 is wound around a drive pulley 32 and two driven pulleys 33. A traverse guide 22 is installed on the generally straight section of the annular belt 34 between the two driven pulleys 33. The annular belt 34 is driven by the rotation of the drive pulley 32 driven by a traverse motor 31, and the traverse guide 22 is reciprocated at least in the front-back direction (axial direction of the bobbin B).

[0068] The traverse guide 22 can be positioned at any location within a predetermined area (movable area) in the front-to-back direction depending on the rotation angle of the traverse motor 31's rotating shaft. That is, the range of movement of the traverse guide 22 can be arbitrarily changed within the movable area. For example, during the winding operation, the traverse guide 22 is positioned in the traverse area T (refer to the traverse region T) used to form the yarn layer YL constituting the package P. Figure 4 It is moved back and forth inside.

[0069] The length of the lateral movement region T in the front-to-back direction can be changed, for example, during the winding operation. Thus, for example, a roll P with a known tapered shape can be formed (see [reference]). Figure 1 ).

[0070] Additionally, the traverse guide 22 can also move outward from the traverse region T. For example, at one end of the bobbin B in the axial direction (in... Figure 4 (The middle part is the front end), the slit S into which the wire Y is hooked is formed over the entire circumferential area of ​​the bobbin B. The traverse guide wire 22 can move in the front-back direction to a position approximately the same as the slit S.

[0071] It should be noted that the structure of the traverse device 30 is not limited to the structure described above. For example, as a drive source, a single traverse motor (not shown) that drives multiple drive pulleys 32 together can be used instead of multiple traverse motors 31 that are provided corresponding to each drive pulley 32.

[0072] The turntable 23 is, for example, a circular plate-shaped component whose axial direction is approximately parallel to the front-rear direction. The turntable 23 is powered by a turntable motor 101 (see reference). Figure 5 It is driven to rotate.

[0073] The two tube supports 24 are each supported by a turntable 23 and are freely rotatable. For example, when viewed from the front and rear directions, the two tube supports 24 are point-symmetrically arranged about the center of rotation axis of the turntable 23 (see reference). Figure 2 The axial direction of each tube support 24 is approximately parallel to the front-to-back direction (refer to...). Figure 1 The rear end of each bobbin support 24 in the front-rear direction is cantilevered by a turntable 23. In other words, the machine base 20 cantilevered the rear end of each bobbin support 24 via a turntable 23. Each bobbin support 24 supports a plurality of bobbins B arranged in the front-rear direction. In this embodiment, each bobbin support 24 supports, for example, six bobbins B. It should be noted that the number of bobbins B that the bobbin support 24 can support is not limited to this. Each of the two bobbin supports 24 is powered by a separate winding motor 102 (see reference 102). Figure 5 The drive rotates. Multiple threads Y are wound together from multiple bobbins B mounted on a bobbin support 24 (refer to bobbin support 24A). This bobbin support 24 is positioned above another bobbin support 24. For ease of explanation, this bobbin support 24 is also referred to as the upper bobbin support 24.

[0074] The contact roller 25 is a roller disposed immediately above the upper bobbin support 24. The axial direction of the contact roller 25 is substantially parallel to the front-to-back direction. The contact roller 25 shapes each of the multiple rolls P by applying contact pressure to the respective surfaces of the multiple rolls P supported on the upper bobbin support 24. The contact roller 25 is driven to rotate by a motor (not shown).

[0075] The temporary thread guide 27 is a thread guide that temporarily holds multiple threads Y suspended on multiple support thread guides 21. It is used to assist the multiple threads Y in being captured by the first thread guide 28 and the second thread guide 29. Figure 2 As shown, the wire storage guide 27 has a rotating shaft 41, a support member 42, and a wire holding part 43. The wire storage guide 27 is positioned forward of the front end of the bobbin support 24.

[0076] like Figure 1 As shown, the support member 40 supports the traverse device 30 and the contact roller 25. The support member 40 extends in a generally longitudinal direction. The rear end of the support member 40 is cantilevered by the machine base 20. The support member 40 supports both ends of the contact roller 25 in the longitudinal direction, allowing it to rotate freely. The portion of the support member 40 that supports the contact roller 25 is configured such that the contact roller 25 can swing in a generally vertical direction between a position where it contacts the multiple rolls P supported on the upper bobbin support 24 and a position where it leaves the rolls P.

[0077] Rotation axis 41 along the front-back direction ( Figure 2 The axis of rotation 41 supports the support member 42 so that it can swing. The support member 42 is, for example, a generally plate-shaped member extending in the vertical and horizontal directions. The support member 42 is supported by the first swing drive unit 103 (see reference 103). Figure 5 In standby position ( Figure 2 as well as Figure 8 The position shown) and the swing position ( Figure 9 , Figure 10 as well as Figure 11 The position is driven to move between the positions shown. The standby position is, for example, a position that does not coincide with the turntable 23 when viewed from the front-rear direction. In the left winding unit 14A, the yarn storage guide 27 in the standby position is located on the right side of the turntable 23 when viewed from the front-rear direction. Multiple yarns Y hanging on the yarn storage guide 27 in the standby position are captured by the yarn holding part 53 (described later) of the first yarn guide 28. The swing position is the position of the support member 42 when the multiple yarns Y captured by the first yarn guide 28 are transferred to the second yarn guide 29. The first swing drive unit 103 may, for example, have a motor (not shown) as the drive source. Alternatively, the first swing drive unit 103 may, for example, have a cylinder (not shown) as the drive source. The first swing drive unit 103 is electrically connected to the control unit 26 (see reference). Figure 5 ).

[0078] The thread holding part 43 is configured to hold multiple threads Y together. For example, the thread holding part 43 has a groove capable of holding multiple threads Y together.

[0079] The first wire guide 28 is used to capture multiple wires Y suspended at multiple support points by the wire guide 21 and transfer the captured multiple wires Y to the second wire guide 29. For example... Figure 2 As shown, the first wire guide 28 has a rotating shaft 51, a support component 52, and a wire holding part 53.

[0080] Rotation axis 51 along the front-back direction ( Figure 2 The axis of rotation 51 supports the support member 52 so that it can swing. The support member 52 is, for example, a generally plate-shaped member extending in the front-to-back direction. The support member 52 is supported by a second swing drive unit 104 (see reference 104). Figure 5 In standby position ( Figure 2 , Figure 8 , Figure 10 as well as Figure 11 The location shown) and the handover location ( Figure 9 The movement is driven between the positions shown. The transfer position is a position to the left of the standby position, which is the position of the wire holding part 53 when the multiple wires Y captured by the wire holding part 53 are transferred to the second wire guide 29. The second swing drive part 104 may have a motor (not shown) as the drive source, for example. Alternatively, the second swing drive part 104 may also have a cylinder (not shown) as the drive source, for example. The second swing drive part 104 is electrically connected to the control part 26 (see reference). Figure 5 ).

[0081] The wire holding section 53 is configured to hold multiple wires Y separately in the front-back direction (axial direction of the bobbin B). The wire holding section 53, for example, has multiple first holding grooves (not shown) corresponding to each of the multiple wires Y. Each of the multiple first holding grooves can capture and hold one wire Y. The multiple first holding grooves are configured to move in the front-back direction, for example, using a cylinder (not shown) as a drive source. Alternatively, the multiple first holding grooves may also be configured to move in the front-back direction, for example, using a linear actuator (not shown) as a drive source. The multiple first holding grooves moving in the front-back direction are configured to move between a close position where they are close to each other and a departure position where they are far apart from each other compared to the close position. The front-back spacing of the multiple first holding grooves located at the departure position is related to the multiple second holding grooves 63a described later (see reference). Figure 4 The front-to-back spacing of the multiple first retaining grooves is approximately the same. It should be noted that the front-to-back spacing of the multiple first retaining grooves refers to the distance between the center positions of adjacent first retaining grooves in the front-to-back direction. Similarly, the front-to-back spacing of the multiple second retaining grooves 63a refers to the distance between the center positions of adjacent second retaining grooves 63a in the front-to-back direction.

[0082] The second wire guide 29 is used to guide multiple wires Y transferred from the first wire guide 28 onto multiple bobbins B mounted on the upper bobbin support 24. For example... Figure 2 As shown, the second wire guide 29 has a rotating shaft 61, a support component 62, and a wire holding part 63.

[0083] Rotation axis 61 along the front-back direction ( Figure 2 The axis of rotation 61 supports the support member 62 so that it can swing. The support member 62 is, for example, a generally plate-shaped member extending in the front-to-back direction. The support member 62 is supported by a third swing drive unit 105 (see reference 105). Figure 5 Driven in standby position ( Figure 2 as well as Figure 8 (as shown in the image) receiving location ( Figure 9 (as shown in the image) Wire hanging position ( Figure 10 as well as Figure 11 The position can be moved between the positions shown. The standby position is, for example, a position that does not coincide with the turntable 23 when viewed from the front-to-back direction. In the left winding unit 14A, the second wire guide 29, located in the standby position, is located to the left of the turntable 23 when viewed from the front-to-back direction. The receiving position is a position to the right of the standby position, and is a position for receiving multiple wires Y from the first wire guide 28 by the wire holding unit 63. The wire hanging position is a position between the standby position and the receiving position in the left-to-right direction, and is a position for hanging the multiple wires Y received by the wire holding unit 63 onto multiple bobbins B respectively. The third swing drive unit 105 may, for example, have a motor (not shown) as the drive source. Alternatively, the third swing drive unit 105 may, for example, have a cylinder (not shown) as the drive source. The third swing drive unit 105 is electrically connected to the control unit 26 (see reference). Figure 5 ).

[0084] The wire holding section 63 is configured to hold multiple wires Y separately in the front-to-back direction (axial direction of the bobbin B). The wire holding section 63, for example, has multiple second holding grooves 63a respectively corresponding to the multiple wires Y (see reference). Figure 4 Each of the multiple second holding slots 63a is capable of capturing and holding a single thread Y. Figure 4 Only one second retaining groove 63a is shown in the figure when the support member 62 is in the wire-hanging position. Near the inlet and outlet of the second retaining groove 63a for the wire Y, for example, a protrusion (not shown) may be provided to prevent the retained wire Y from slipping off. The longitudinal spacing of the plurality of second retaining grooves 63a is approximately the same as the longitudinal spacing of the plurality of bobbins B. It should be noted that the longitudinal spacing of the plurality of bobbins B refers to the distance between the center positions of adjacent bobbins B in the longitudinal direction.

[0085] The second wire guide 29, for example, is composed of a moving drive unit 106 (see reference). Figure 5 Driven to move in the forward and backward direction (refer to) Figure 4 (The arrow is shown). The motion drive unit 106 may, for example, have a cylinder (not shown) as the drive source. Alternatively, the motion drive unit 106 may also have a linear actuator (not shown) as the drive source. The motion drive unit 106 is electrically connected to the control unit 26 (see reference). Figure 5 The thread holding part 63 is in, for example, a rear position (see reference 106) by the moving drive part 106. Figure 4 The double-dotted line) and the previous position (refer to) Figure 4 The movement is driven between the dotted lines. The rear position is the position of the wire holding part 63 when multiple wires Y are captured by multiple second holding grooves 63a respectively. The front position is the position of the wire holding part 63 when multiple wires Y are hung on the slit S of the empty bobbin B.

[0086] The control unit 26 includes a CPU, ROM, RAM, etc. (not shown). Figure 5 As shown, the control unit 26 is electrically connected to various parts of the thread winding device 13 (such as the traverse motor 31, turntable motor 101, and winding motor 102 mentioned above). The control unit 26 is configured to control the operation of each part of the thread winding device 13.

[0087] In the yarn winding device 13 with the above structure, 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 bobbin B to form a roll P. Furthermore, when the roll P is fully wound, the upper and lower positions of the two bobbin supports 24 are reversed by rotating the turntable 23. As a result, the lower bobbin support 24 moves to the upper side. Multiple yarns Y are wound onto the multiple bobbins B mounted on the upper bobbin support 24 to form multiple rolls P. Additionally, the bobbin support 24, which is equipped with the multiple fully wound rolls P, is moved to the lower side. The multiple fully wound rolls P are then recovered, for example, by a roll recovery device (not shown).

[0088] The yarn winding device 13 also includes a tension meter 71 (see reference). Figure 1 , Figure 6 as well as Figure 7 ), front cover 72 (the cover of this utility model, see reference) Figure 1 , Figure 6 as well as Figure 7 ) and operation panel 73 (see reference) Figure 6 as well as Figure 7 ).

[0089] Tension gauge 71 is a device for measuring the tension of one of a plurality of wires Y. Tension gauge 71 is, for example, a tension gauge using a known strain gauge. Tension gauge 71 is configured to measure the tension of a traveling wire Y. In other words, tension gauge 71 is configured to measure the tension of a wire Y captured by the traversing device 30. Tension gauge 71 is, for example, fixedly disposed upstream of one of a plurality of fulcrum wire guides 21 in the direction of wire travel (see reference). Figure 1 The single pivot guide 21 can be, for example, the pivot guide 21 located at the foremost of a plurality of pivot guides 21 (see reference). Figure 1 In this embodiment, the tension meter 71 is fixed to one of the plurality of fulcrum guides 21 at an upstream position in the direction of yarn travel. The tension meter 71 is configured to continuously measure the tension of the yarn Y.

[0090] In addition, such as Figure 6 As shown, the tension gauge 71 is configured corresponding to the left winding unit 14A of a pair of winding units 14A and 14B. However, the tension gauge 71 may also be configured corresponding to the right winding unit 14B.

[0091] like Figure 1 as well as Figure 7 As shown, a front cover 72 is provided at the front end of the support member 40 (the top end of the support member of this invention). In other words, the support member 40 has a front cover 72 provided at the front end. The front cover 72 is, for example, a member for covering at least a portion of the structural elements of each winding unit 14 from the front. In this embodiment, the front cover 72 is a member that covers the front end of the upper bobbin support 24A. In addition, the front cover 72 has the function of protecting the motor (not shown) that drives the rotation of the contact roller 25, the traverse motor 31, the cylinder (not shown) that drives the swing of the support member 40, and the base plate (not shown) that is electrically connected to the operation panel 73. The front cover 72 is a generally box-shaped member with a rear opening. The front surface 72a of the front cover 72 (the top end surface of the cover of this invention) extends at least in the vertical direction and the horizontal direction. In this embodiment, the front surface 72a of the front cover 72 is positioned further forward than the front end of the bobbin support 24. Figure 6 As shown, when viewed from the front-rear direction, the lower end of the front cover 72 is located below the upper end of the upper bobbin support 24. When viewed from the front-rear direction, the front cover 72 is, for example, positioned to coincide with the traverse wire guide 22 and the second wire guide 29. However, the structure of the front cover 72 is not limited to the structure of this embodiment, and it may not be a component that covers the front end of the upper bobbin support 24A.

[0092] The control panel 73 is used to input signals for the operation of various parts of the yarn winding device 13. The control panel 73 is positioned within the visual range of the operator who operates the suction gun 80 (described later) to perform yarn winding operations on multiple bobbins B. Specifically, the control panel 73 is mounted on the front surface 72a of the front cover 72 (see reference 72a). Figure 6 as well as Figure 7 However, the control panel 73 can also be mounted via a bracket in a location easily accessible to the operator. This easily accessible location could be, for example, a position different from the front cover 72 of the support member 40, or another structural component of the thread winding device 13. Figure 7 As shown, the operator operates the suction gun 80 from a position forward of the front cover 72 to perform wire-coating operations onto multiple bobbins B. Therefore, the operation panel 73, mounted on the front surface 72a of the front cover 72, is positioned within the view of the operator operating the suction gun 80. Figure 6 as well as Figure 7 As shown, the operation panel 73 is provided with a plurality of (e.g., five) buttons 74. These buttons 74 include, for example, a button for inputting a signal to execute the action of ejecting roll P from the left take-up unit 14A; a button for inputting a signal to execute the action of ejecting roll P from the right take-up unit 14B; and a button for inputting a signal to stop the take-up action. For example, the operation panel 73 located on the left take-up unit 14A and the operation panel 73 located on the right take-up unit 14B can be configured with buttons for performing different actions.

[0093] In addition, such as Figure 6 As shown, the operation panel 73 has multiple (e.g., five) lights 75. Each light 75 is associated with a multiple button 74. For example, pressing a button 74 once will turn on the corresponding light 75, and pressing the button 74 twice will turn off the corresponding light 75.

[0094] like Figure 6 As shown, a display unit 76 is provided on the operation panel 73 of the left winding unit 14A, which is one of a pair of winding units 14. The display unit 76 displays the tension value of the yarn Y measured by the tension meter 71. The display unit 76 is, for example, an LED display.

[0095] In this embodiment, the display unit 76 is integrally formed with the operation panel 73, but it can also be set independently of the operation panel 73. The display unit 76 is positioned in a position that the operator operating the suction gun 80 can see when performing wire-coating operations on multiple bobbins B. For example, the display unit 76 is mounted on the support member 40. Alternatively, the display unit 76 can be mounted via a bracket in a position easily visible to the operator. Such a position could be, for example, the support member 40, or other structural components of the wire winding device 13. Preferably, the display unit 76 is mounted on the front end of the support member 40. Furthermore, in the case where the support member 40 has a structure with a front cover 72, as in this embodiment, ... Figure 7 As shown, more preferably, the display portion 76 is provided on the front cover 72 provided at the front end of the support member 40. Figure 7 As shown, more preferably, the display 76 is mounted on the front surface 72a of the front cover 72. In other words, more preferably, the display 76 is mounted on the front end side of the front cover 72. The display 76 can also be mounted via a bracket in a position easily visible to the operator.

[0096] (A summary of the wire-hanging process on the bobbin)

[0097] Next, refer to Figures 8 to 11 The outline of the process for attaching wire Y to a bobbin B mounted on a bobbin support 24 (let's say bobbin support 24A) is described below. In this embodiment, attaching wire to the bobbin B is performed by an operator operating a suction gun 80 (see...). Figure 7 (etc.) The suction gun 80 is a component that simultaneously attracts and holds multiple filaments Y. The filaments are loaded onto the bobbin B starting from a position forward of the front end of the bobbin support 24 (i.e., the open end of the bobbin support 24). It should be noted that the filaments Y loaded onto the bobbin B are, for example, fine-grained filaments with a total fineness of 30 dtex or less. Since the finer the fineness, the lower the breaking strength, it is necessary to reduce the tension during loading. On the other hand, if the tension during loading is too low, the filaments Y will slack due to the frictional resistance of the guide roller on the upstream side of the suction gun 80. Thus, the slack filaments Y will wind onto the second guide roller 12, etc., inducing breakage before being loaded onto the bobbin B. Therefore, the finer the fineness of the filaments Y, the more careful attention needs to be paid to the tension during loading. However, the filaments Y loaded onto the bobbin B are not limited to fine-grained varieties.

[0098] In this embodiment, wires are simultaneously wound onto each bobbin B of the left winding unit 14A and each bobbin B of the right winding unit 14B. With multiple wires Y wound onto each bobbin B of the left winding unit 14A and multiple wires Y wound onto each bobbin B of the right winding unit 14B held together by the suction gun 80, the wires Y are wound onto each bobbin B of both the left and right winding units 14 by operating the suction gun 80. Since the wire-hanging process is the same for both the left and right winding units 14, the description of the wire-hanging process for each bobbin B of the right winding unit 14B is omitted. Figures 8 to 11 In the diagram, only the left-side winding unit 14A is shown.

[0099] First, in the initial state, no yarn Y is wound on the bobbin B mounted on the bobbin support 24A and on the bobbin B mounted on another bobbin support 24 (designated as bobbin support 24B). Also, in the initial state, the support member 42 of the yarn storage guide 27 is in the standby position, the support member 52 of the first yarn guide 28 is in the standby position, and the support member 62 of the second yarn guide 29 is in the standby position. Furthermore, the plurality of first retaining grooves (not shown) of the yarn holding portion 53 of the first yarn guide 28 are in the approach position. In addition, the yarn holding portion 63 of the second yarn guide 29 is in the rear position (see reference). Figure 4 (The double-dotted line).

[0100] like Figure 8 As shown, by operating the suction gun 80, multiple threads Y hanging on the multiple fulcrum guides 21 are simultaneously hooked onto the thread storage guide 27. The multiple threads Y, after being hooked onto the thread storage guide 27, are captured by multiple first holding slots (not shown) provided in the first thread hook guide 28. At this time, the operator refers to the display unit 76 (see reference 76) while observing the threads. Figure 6 The tension value of the thread Y is displayed, and the suction pressure of the suction gun 80 is adjusted to appropriately adjust the tension of the thread Y.

[0101] Next, the control unit 26 controls the third swing drive unit 105 to swing the second wire guide 29, causing the support member 62 to move from the standby position to the receiving position (see reference). Figure 9 (Solid arrow). Next, the control unit 26 controls the turntable motor 101 to rotate the turntable 23 clockwise (see reference). Figure 9 (Solid arrow). As a result, each bobbin support 24 moves to a position where the bobbin support 24 and the first wire guide 28 will not interfere even if the first wire guide 28 swings. Then, the control unit 26 moves the plurality of first retaining grooves (not shown) provided in the wire holding unit 53 from the approach position to the departure position. This allows the front-rear spacing of the plurality of first retaining grooves to be aligned with the front-rear spacing of the plurality of second retaining grooves 63a.

[0102] Next, the control unit 26 controls the second swing drive unit 104 to swing the first wire guide 28, causing the support member 52 to move from the standby position to the handover position (see reference). Figure 9 (Solid arrow). Thus, the multiple threads Y captured by the thread holding portion 53 of the first thread guide 28 come into contact with the thread holding portion 63 of the second thread guide 29. Furthermore, the control unit 26 controls the first swing drive unit 103 to swing the thread temporary guide 27, causing the support member 42 to move from the standby position to the swing position (see reference). Figure 9 (Solid arrow). As the support member 42 moves, multiple wires Y are transferred from the first wire guide 28 located in the transfer position to the second wire guide 29 located in the receiving position.

[0103] Next, the control unit 26 controls the second swing drive unit 104 to swing the first wire guide 28, causing the support member 52 to move from the handover position to the standby position (see reference). Figure 10 (Solid arrow). As a result, multiple threads Y are disengaged from the first thread guide 28. Next, the control unit 26 controls the turntable motor 101 to rotate the turntable 23 counterclockwise (see reference). Figure 10 (Solid arrow). Thus, each bobbin support 24 moves to a position where the bobbin support 24 and the second wire guide 29 will not interfere even if the second wire guide 29 swings.

[0104] Subsequently, the control unit 26 controls the third swing drive unit 105 to swing the second wire guide 29, causing the support member 62 to move from the receiving position to the wire hanging position (see reference). Figure 10 (Solid arrow). Next, the control unit 26 controls the traverse motor 31 to cause multiple traverse wire guides 22 to capture multiple wires Y.

[0105] Next, the control unit 26 controls the turntable motor 101 to cause the turntable 23 to rotate further counterclockwise (see reference). Figure 11 (Solid arrow). As a result, the multiple bobbins B assembled on the bobbin support 24A move to a position close to the multiple wires Y held by the wire holding part 63 of the second wire guide 29 located in the wire holding position.

[0106] Next, the control unit 26 controls the movement drive unit 106 to move the thread holding unit 63 from the rear position in the front-to-back direction (see reference). Figure 4 The double-dotted line) forward position (refer to) Figure 4The dotted line moves. As a result, the multiple threads Y held by the thread holding part 63 of the second thread guide 29 approach the slits S formed in each bobbin B. Next, the control unit 26 controls the traverse motor 31 to move the multiple traverse thread guides 22 to positions corresponding to the slits S. Thus, the multiple threads Y are hooked onto the slits S formed in each bobbin B, ending the thread hooking process on each bobbin B mounted on the bobbin support 24A.

[0107] (Effect)

[0108] The yarn winding device 13 of this embodiment includes: a bobbin support 24, on which a plurality of bobbins B are arranged in a front-to-back direction; a traversing device 30; a contact roller 25; a support member 40 supporting the traversing device 30 and the contact roller 25; a machine base 20 cantileveredly supporting the rear end of the bobbin support 24 and the rear end of the support member 40; a tension meter 71 for measuring the tension of yarn Y attached to at least one of the plurality of bobbins B; and a display unit 76 for displaying the tension value of yarn Y measured by the tension meter 71. The display unit 76 is positioned in a location visible to the operator operating the suction gun 80 for winding yarn onto the plurality of bobbins B. According to this embodiment, the display unit 76, which displays the tension value of yarn Y attached to the bobbins B, is positioned in a location visible to the operator operating the suction gun 80 for winding yarn onto the plurality of bobbins B. Therefore, the operator performing the wire-hanging operation can operate the suction gun 80 while simultaneously observing the tension value of the wire Y displayed on the display unit 76, making it easy to control the tension value of the wire Y. In particular, the structure of this embodiment is even more effective when the tension of the wire Y held by the suction gun 80 is low and there is a great need to accurately control the tension of the wire Y.

[0109] Furthermore, in the thread winding apparatus 13 of this embodiment, the display unit 76 is mounted on the front end of the support member 40. It should be noted that the front end of the support member 40 refers to the area near the front end of the support member 40. Generally, the thread winding operation using the suction gun 80 begins from the front end side of the support member 40. According to this embodiment, the display unit 76 is mounted on the front end of the support member 40, which is easily visible to the operator operating the suction gun 80. Therefore, the operator can more easily monitor the tension of the thread Y.

[0110] Furthermore, in the thread winding apparatus 13 of this embodiment, the support member 40 has a front cover 72 provided at the front end, and a display 76 is mounted on the front cover 72. Thus, the display 76 is mounted on the front cover 72, which is easily visible to the operator operating the suction gun 80. Therefore, the operator can more easily control the tension of the thread Y.

[0111] Furthermore, in the thread winding apparatus 13 of this embodiment, the display unit 76 is mounted on the front surface 72a of the front cover 72. In this embodiment, the front surface 72a corresponds to the top surface of the front cover 72. The operator operating the suction gun 80 faces the front surface 72a of the front cover 72 when performing operations. According to this embodiment, since the display unit 76 is mounted on the front surface 72a of the front cover 72, which is easily visible to the operator operating the suction gun 80, the operator operating the suction gun 80 can easily make visual identification. Therefore, the operator can more easily grasp the tension of the thread Y. It should be noted that, depending on the shape of the front cover 72, the display unit 76 may also be mounted on a portion of the front cover 72 that is different from the front surface 72a, and is located at the front end of the front cover 72. In this case, the front end of the front cover 72 becomes a position that is easier for the operator to visually identify.

[0112] Furthermore, in the yarn winding apparatus 13 of this embodiment, the tension gauge 71 is fixedly disposed on the upstream side of the bobbin support 24 in the yarn travel direction Y. Therefore, the operator does not need to operate the tension gauge 71, and the yarn winding operation can be easily performed. In addition, since there is sufficient space upstream of the bobbin support 24 in the yarn travel direction, it is easy to install the tension gauge 71.

[0113] Furthermore, the thread winding apparatus 13 of this embodiment has multiple fulcrum guides 21 arranged corresponding to the multiple threads Y wound on multiple bobbins B. A tension meter 71 is disposed upstream of one of the multiple fulcrum guides 21 in the thread travel direction. In this embodiment, a tension meter 71 is disposed upstream of one of the multiple fulcrum guides 21 in the thread travel direction, and the tension of one of the multiple threads Y is used as a representative measurement. This simplifies the structure of the thread winding apparatus 13 by eliminating the need to provide multiple tension meters 71 corresponding to each of the multiple threads Y.

[0114] Furthermore, the thread winding device 13 of this embodiment includes a pair of winding units 14A and 14B arranged facing each other in the left-right direction. The display unit 76 is provided corresponding to one of the winding units 14A and 14B. According to this embodiment, when thread is wound onto each bobbin B provided in the pair of winding units 14A and 14B simultaneously, the operator only needs to check the display unit 76 provided corresponding to one winding unit 14A. Therefore, the operator will not be confused about where to look and can easily grasp the tension value of the thread Y.

[0115] (Modified Example)

[0116] Hereinafter, variations of the above embodiments will be described. However, for components having the same structure as those in the above embodiments, the same reference numerals will be used and their descriptions will be omitted as appropriate.

[0117] In the above embodiment, the display unit 76 is mounted on the front surface 72a of the front cover 72. However, the display unit 76 may also be mounted on the upper surface or right side of the front cover 72 instead of the front surface 72a. When the display unit 76 is mounted on the upper surface (or right side) of the front cover 72, the display unit 76 becomes a structure that protrudes outward from the upper side (or right side) of the front cover 72, so that the operator can see it from the front side of the front cover 72. Alternatively, the display unit 76 may be disposed on the upper side of the front cover 72, or on the left side of the left winding unit 14A (or the right side of the right winding unit 14B).

[0118] In the above embodiment, the display unit 76 is provided on the operation panel 73. However, the display unit 76 may also be provided separately from the operation panel 73. The display unit 76, provided separately from the operation panel 73, is positioned in a location that the operator operating the suction gun 80 can see when performing wire-coating operations on the multiple bobbins B. In this case, the display unit 76 is preferably mounted on the front cover 72, and more preferably on the front surface 72a of the front cover 72. In addition, the position of the operation panel 73 is not limited to the position shown in the above embodiment. The operation panel 73 can be positioned in a location that the operator can access.

[0119] In the above embodiment, the tension meter 71 is disposed upstream of the yarn travel direction of a single fulcrum guide 21. However, multiple tension meters 71 may also be disposed upstream of the respective yarn travel directions of multiple fulcrum guides 21. In this case, the display unit 76 may, for example, display the individual tension values ​​of the multiple yarns Y measured by each tension meter 71, or it may display the average value. In this case, preferably, the tension meter 71 is fixedly disposed upstream of the bobbin support 24. For example, preferably, the tension meter 71 is fixedly disposed between the bobbin support 24 and the second guide roller 12 in the yarn travel direction.

[0120] The thread winding device 13 of the above embodiment has a pair of winding units 14A and 14B arranged facing each other in the left-right direction. However, the thread winding device 13 may also be configured to have only one winding unit 14.

[0121] In the above embodiment, the display unit 76 is provided corresponding to the left winding unit 14A. However, the display unit 76 may also be provided corresponding to the right winding unit 14B. In addition, the display unit 76 may be provided corresponding to both the left winding unit 14A and the right winding unit 14B.
