Description

TECHNICAL FIELD

[0001] The present application relates to a waxing device and a yarn winding device. BACKGROUND

[0002] Conventionally, a waxing device that waxes a traveling yarn is known.

[0003] For example, in the specification of German Patent Application Publication No. 102006018838, a waxing device that brings a wax molding body into contact with at least a portion of a traversing region of a yarn is described in the case where the yarn forms a traversing region and is traversed.

[0004] In the above-described waxing device, for example, the position of the yarn with respect to the wax molding body tends to become unstable as the wax molding body comes into contact with the traversing region of the yarn. In this case, the amount of wax consumed in the wax molding body can become unstable. SUMMARY

[0005] Therefore, an object of the present application is to provide a waxing device and a yarn winding device that can stabilize the amount of wax consumed.

[0006] The waxing device of the present application is a waxing device that waxes a traveling yarn, and includes a wax support portion that supports a wax molding body in such a manner that the wax molding body comes into contact with at least a portion of a traversing region of the yarn; a first guide portion that is provided on a downstream side with respect to a traveling direction of the yarn with respect to the wax molding body and guides the yarn; a second guide portion that is provided on an upstream side with respect to the traveling direction of the yarn with respect to the wax molding body and guides the yarn; and a third guide portion that is provided on the downstream side with respect to the traveling direction of the yarn with respect to the wax molding body and guides the yarn on a downstream side of the first guide portion, the second guide portion is provided on the wax molding body side with respect to a yarn passage of the yarn, and restricts movement of the yarn to the wax molding body side, the third guide portion is provided on the wax molding body side with respect to the yarn passage, and restricts movement of the yarn to the wax molding body side, and the first guide portion is provided on an upstream side of the third guide portion and on an opposite side to the wax molding body side with respect to the yarn passage, and restricts movement of the yarn to the opposite side.

[0007] In the waxing device, movement of the yarn to the side opposite to the wax molding body side is restricted by the first guide portion, and movement of the yarn to the wax molding body side is restricted by the second guide portion and the third guide portion, so that the position of the yarn with respect to the wax molding body can be stabilized. Thus, the yarn can be brought into appropriate contact with the wax molding body. Therefore, the amount of wax consumed can be stabilized.

[0008] In the waxing device of the present application, the first guide portion can be a first rectangular plate portion that has a planar side surface along the traversing region, and the traveling direction of the yarn is set as a thickness direction. According to this structure, the position of the yarn with respect to the wax molding body can be stabilized by a simple structure.

[0009] In the waxing device of the present application, the second guide portion can also be a second rectangular plate portion having planar sides along the lateral region, with the yarn travel direction being set as the thickness direction. According to this structure, the position of the yarn relative to the wax molded body can be stabilized by a simple structure.

[0010] In the waxing device of the present application, the third guide portion can also be a third rectangular plate portion having planar sides along the lateral region, with the yarn travel direction being set as the thickness direction. According to this structure, the position of the yarn relative to the wax molded body can be stabilized by a simple structure.

[0011] The waxing device of the present application can also have a guide support member that is fixed to the frame and supports the first guide portion and the second guide portion. According to this structure, the first guide portion and the second guide portion can be fixed to the frame together via the guide support member, and the first guide portion and the second guide portion can be stably configured integrally.

[0012] The waxing device of the present application can also have a positioning portion having three or more abutting portions that abut against the wax molded body and perform positioning of the wax molded body, the positioning portion being supported by the guide support member. According to this structure, the positioning accuracy of the positioning portion with respect to the wax molded body can be ensured by the three or more abutting portions abutting against the wax molded body. In addition, the first guide portion, the second guide portion, and the positioning portion can be fixed to the frame together via the guide support member, and the first guide portion, the second guide portion, and the positioning portion can be stably configured integrally.

[0013] In the waxing device of the present application, the positioning portion can position the wax molded body so that, as viewed from the yarn travel direction, the end portion of the wax molded body disposed in the lateral region is positioned between the first guide portion and the second guide portion. According to this structure, the functions of the first guide portion and the second guide portion can be effectively exerted.

[0014] In the waxing device of the present application, the positioning portion can position the wax molded body so that, as viewed from the yarn travel direction, the end portion of the wax molded body disposed in the lateral region is positioned between the first guide portion and the third guide portion. According to this structure, the functions of the first guide portion and the third guide portion can be effectively exerted.

[0015] In the waxing device of the present application, the distance between the first guide portion and the second guide portion can be greater than the distance between the first guide portion and the third guide portion in a direction perpendicular to the lateral region. According to this structure, the respective functions of the first to third guide portions can be effectively exerted.

[0016] In the waxing device of the present application, the first guide portion can also guide the yarn on the immediately upstream side of the third guide portion. According to this structure, the respective functions of the first guide portion and the third guide portion can be effectively exerted.

[0017] In the waxing device of the present application, the wax support portion can also support the wax molding body in such a manner that one end surface of the wax molding body faces the front side of the waxing device and the one end surface of the wax molding body contacts at least a portion of the traversing region of the yarn. According to this structure, even in the case where the one end surface of the wax molding body that contacts a portion of the traversing region of the yarn faces the front side, the yarn can be brought into appropriate contact with the wax molding body.

[0018] The yarn winding device of the present application is provided with the above-described waxing device. In this yarn winding device, the same effects as the above-described effects are also achieved, that is, the effect that the amount of consumed wax can be stabilized.

[0019] According to the present application, a waxing device and a yarn winding device that can stabilize the amount of consumed wax can be provided. BRIEF DESCRIPTION OF DRAWINGS

[0027] Hereinafter, a preferred embodiment of the present application will be explained in detail with reference to the drawings. In addition, in the explanation of the drawings, the same or equivalent components are denoted by the same symbols, and repeated explanation will be omitted. "Upstream" and "downstream" respectively mean the upstream and downstream of the traveling direction of the yarn at the time of spinning (one example of the traveling direction of the yarn).

[0028] As Figure 1As shown, the automatic winder 1 is provided with a plurality of winder units (yarn winding devices) 2 arranged in a row, a machine control device 3, a spool supply device 4, a doffer device 5, and an air blower box which is not shown.

[0029] The machine control device 3 is configured to be able to communicate with each of the winder units 2. An operator of the automatic winder 1 appropriately operates the machine control device 3, whereby it is possible to centrally manage the plurality of winder units 2. The machine control device 3 controls the actions of the spool supply device 4 and the doffer device 5.

[0030] The spool supply device 4 places the spools 21 one by one on the transport tray 26. The spool supply device 4 supplies the spools 21 placed on the transport tray 26 to each of the plurality of winder units 2.

[0031] The doffer device 5 travels to the position of the winder unit 2 in which the package 30 has become a full package (a state in which a prescribed amount of yarn 20 has been wound) and removes the full package 30. The doffer device 5 places an empty take-up spool 22 at the winder unit 2 from which the package 30 has been removed.

[0032] Next, the structure of the winder unit 2 will be described. As shown in Figure 2 The winder unit 2 is provided with a feed section 6, a yarn accumulation device 18, a package forming section 8, and a waxing device 70. In the winder unit 2, the yarn 20 of the spool 21 of the feed section 6 is unwound, and after the unwound yarn 20 is temporarily accumulated by the yarn accumulation device 18, it is wound on the take-up spool 22 to form the package 30.

[0033] The feed section 6 is configured to support the spool 21 placed on the transport tray 26 at a prescribed position and is able to unwind the yarn 20 from the spool 21. If the feed section 6 unwinds all of the yarn 20 from the spool 21, it discharges the empty spool 21 and receives the supply of a new spool 21 from the spool supply device 4.

[0034] The yarn accumulation device 18 is disposed between the feed section 6 and the package forming section 8. The yarn accumulation device 18 is disposed at a position on the upstream side of the yarn 20 in the direction of travel with respect to the waxing device 70. The yarn accumulation device 18 winds and temporarily accumulates the yarn 20 unwound by the feed section 6. The yarn accumulation device 18 supplies the accumulated yarn 20 to the package forming section 8. The yarn accumulation device 18 is provided with a yarn accumulation roller 32 that is able to wind the yarn 20, and a roller drive motor 33 that rotates and drives the yarn accumulation roller 32. The roller drive motor 33 rotates the yarn accumulation roller 32 in a direction in which the yarn 20 from the feed section 6 is wound. In addition, the roller drive motor 33 is also able to rotate the yarn accumulation roller 32 in a direction opposite to the winding direction.

[0035] The package forming section 8 has a creel 23 configured to be able to mount the take-up bobbin 22, and a traverse roller 24 that drives the take-up bobbin 22 while traversing the yarn 20. The package forming section 8 constitutes a take-up section. The creel 23 rotatably supports the take-up bobbin 22 (or the package 30). The creel 23 is configured to be able to bring the outer peripheral surface of the supported package 30 into contact with the outer peripheral surface of the traverse roller 24.

[0036] The traverse roller 24 is rotationally driven by a drive source (electric motor or the like) not shown in the figure, and rotates in a state of being in contact with the outer peripheral surface of the take-up bobbin 22 or the package 30, thereby rotationally driving the take-up bobbin 22. Thus, the yarn 20 accumulated in the yarn accumulation device 18 can be unreeled and drawn out to be wound on the take-up bobbin 22. A traverse groove not shown in the figure is formed in the outer peripheral surface of the traverse roller 24, and the yarn 20 can be caused to traverse (traverse) by a predetermined width through the traverse groove. In the above structure, the yarn 20 can be wound on the take-up bobbin 22 while being caused to traverse, thereby forming a package 30 of a predetermined shape.

[0037] The waxing device 70 is disposed between the yarn accumulation device 18 and the package forming section 8. The waxing device 70 waxes the yarn 20 that travels from the yarn accumulation device 18 toward the package forming section 8. The detailed structure of the waxing device 70 will be described later.

[0038] The winding machine unit 2 has various devices in the yarn travel path from the feed section 6 via the yarn accumulation device 18 to the package forming section 8. Specifically, on the yarn passage (yarn travel path) of the yarn 20, from the upstream feed section 6 side toward the downstream yarn accumulation device 18 side, there are disposed, in this order, the unreeving assisting device 10, the lower yarn finger 11, the tension applying section 12, the catching device 13, the joint device 14, the yarn monitoring device 16, and the downstream yarn blowing section 48.

[0039] The unreeving assisting device 10 swings the movable member 27 in contact with the loop formed on the upper portion of the feed bobbin 21 from the yarn 20 unreeled from the feed bobbin 21, and appropriately controls the size of the loop, thereby assisting the unreeving of the yarn 20.

[0040] The lower yarn finger 11 is disposed at a position close to the unreeving assisting device 10 on the downstream side of the unreeving assisting device 10. The lower yarn finger 11 defines the position of the yarn 20 supplied from the unreeving assisting device 10.

[0041] The tension applying section 12 applies a prescribed tension to the traveling yarn 20. The tension applying section 12 applies a prescribed tension to the yarn 20 based on the tension of the yarn 20 detected by a tension sensor, which is omitted from the illustration. The tension applying section 12 is configured as a gate in which movable comb teeth are arranged with respect to fixed comb teeth, and applies a prescribed resistance by causing the yarn 20 to travel between the comb teeth. The comb teeth on the movable side are configured to be movable, for example, by a solenoid, so as to bring the comb teeth into an engaged state or a disengaged state with respect to each other. Thus, the tension applying section 12 is able to adjust the tension applied to the yarn 20. Furthermore, the configuration of the tension applying section 12 is not particularly limited, and can be, for example, a disc-type tension applying section.

[0042] The capturing device 13 is arranged on the downstream side of the tension applying section 12. The capturing device 13 has a first capturing section 13A and a second capturing section 13B. In the present embodiment, the first capturing section 13A and the second capturing section 13B are configured as one member. Each of the first capturing section 13A and the second capturing section 13B is connected to a negative pressure source, which is omitted from the illustration. Furthermore, each of the first capturing section 13A and the second capturing section 13B can be configured as a different member.

[0043] The first capturing section 13A is configured as a cylindrical member in which an opening is formed in the front end portion. The first capturing section 13A generates a suction air flow at the joint time, and sucks and captures the yarn 20 on the side of the yarn storage device 18.

[0044] The second capturing section 13B is configured as a cylindrical member in which an opening is formed in the front end portion. The second capturing section 13B is arranged so as to be able to swing. The second capturing section 13B swings between a capturing position (a position indicated by a solid line in FIG. 8) at which the yarn 20 pulled out from the yarn feeding tube 21 is captured, and a guide position (a position indicated by a broken line in FIG. 8) at which the yarn 20 is guided toward the joint device 14. Figure 2 Figure 2 The capturing position can also be a standby position of the second capturing section 13B.

[0045] The second capturing section 13B generates a suction air flow at the front end side thereof in a state in which the yarn passage is approached on the downstream side of the lower yarn finger 11 at the capturing position, and thereby sucks and captures the yarn end pulled out from the yarn feeding tube 21. The second capturing section 13B sucks and captures the yarn end on the side of the yarn feeding tube 21 of the yarn 20 after the yarn 20 is cut by the cutter 15. In addition, the second capturing section 13B can be configured to suck and remove fluff and the like attached to the traveling yarn 20 by generating a suction air flow at the front end side thereof.

[0046] ​An auxiliary blowing section 28 is provided, which blows the thread end to a position on the downstream side of the lower thread finger 11 (the tip of the second catching section 13B) in the case where the thread 20 is caught by the second catching section 13B immediately after a new feed spool 21 is supplied to the feed section 6.

[0047] The auxiliary blowing section 28 ejects compressed air to the inside of the feed spool 21 and the delivery tray 26 formed in a hollow shape, thereby forming an air current that blows the thread 20 of the feed spool 21 to the side of the lower thread finger 11 at the tip of the feed spool 21. In the case where the newly supplied feed spool 21 is supported by the feed section 6, the thread end on the side of the feed spool 21 can be reliably delivered toward the side of the lower thread finger 11 by the operation of the auxiliary blowing section 28.

[0048] A joint device 14 performs the joint of the broken thread 20. The joint device 14 performs the joint of the thread 20 on the side of the feed spool 21 and the thread 20 on the side of the thread storage device 18 in the state where the thread 20 between the feed spool 21 and the thread storage device 18 is broken, such as when the thread 20 is cut by the thread monitor device 16 detecting a defect and the thread cutter 15, when the thread 20 being unwound from the feed spool 21 is cut, or when the feed spool 21 is replaced. The joint device 14 is disposed at a position slightly withdrawn from the thread passage. The joint device 14 can set the thread 20 to a continuous state by linking the thread ends introduced to each other. As the joint device 14, a device using a fluid such as compressed air, a mechanical device can be used.

[0049] The thread monitor device 16 monitors the thickness and the like of the thread 20 with an appropriate sensor, thereby detecting defects such as thick spots and foreign matter mixing. The thread cutter 15 is disposed at a position close to the thread monitor device 16 on the upstream side of the thread monitor device 16. The thread cutter 15 immediately cuts the thread 20 in the case where the thread monitor device 16 detects a defect. The thread cutter 15 and the thread monitor device 16 are housed in a common housing 19. The housing 19 housing the thread monitor device 16 is disposed on the downstream side of the joint device 14.

[0050] The downstream thread blowing section 48 is a suction device disposed at a position close to the thread storage device 18 on the upstream side of the thread storage device 18. The downstream thread blowing section 48 forms an air current that blows the thread end on the side of the thread storage device 18 and delivers it to the first catching section 13A by ejecting compressed air. Specifically, the downstream thread blowing section 48 has a guide member (omitted from the drawing) in a thin tubular shape through which the thread 20 can pass inside, and a thread guide member 60 which is a curved tubular member. An exit for the thread 20 is formed at one end of the guide member. The thread guide member 60 is disposed so as to be close to the exit of the downstream thread blowing section 48. Openings are respectively formed at both ends in the longitudinal direction of the thread guide member 60.

[0051] The yarn guide member 60 is disposed so that the opening on one end side thereof opposes the discharge port of the downstream yarn blowing portion 48 and so that the opening on the other end side thereof opposes the first catching portion 13A. A guide path is formed inside the yarn guide member 60. The guide path links the openings on the two ends of the yarn guide member 60 to each other in a manner so as to bypass the yarn monitoring device 16, the joint device 14, and the like. The downstream yarn blowing portion 48, the yarn guide member 60, and the first catching portion 13A constitute the accumulation-side end-of-yarn catching device 50.

[0052] The downstream yarn blowing portion 48, in a case where the yarn 20 becomes in a disconnected state between the yarn feeding tube 21 and the yarn accumulation device 18, catches the yarn 20 on the yarn accumulation device 18 side and blows it toward the guide path of the yarn guide member 60, pulls out the yarn 20 along the guide path, and is caught by the first catching portion 13A. Further, the yarn guide member 60 is formed with a through-like slit, not shown, over the entire length, so that in a state where the yarn 20 is caught by the first catching portion 13A, it is possible to pull out the yarn 20 from inside the yarn guide member 60. According to the above, it is possible to blow the yarn 20 on the yarn accumulation device 18 side by the downstream yarn blowing portion 48 and guide it toward the joint device 14 side.

[0053] Each winding machine unit 2 is provided with a control portion 25. The control portion 25 is provided with a CPU, a ROM, a RAM, and the like, not shown, of hardware. A control program and the like of software are stored in the RAM. The control portion 25 controls each structure of the winding machine unit 2 by cooperation of the hardware and the software. The control portion 25 is configured to be able to communicate with the machine base control device 3. Thereby, it is possible to centrally manage the actions of the plurality of winding machine units 2 provided in the automatic winding machine 1 in the machine base control device 3.

[0054] Next, the waxing device 70 of one embodiment will be described in detail. In the following description, the "front side" and the "back side" refer to the front side (front side) and the back side (rear side) of the winding machine unit 2, respectively. The "X direction" corresponds to the cross direction of the yarn 20.

[0055] In the waxing device 70, the wax forming body W is disposed so as to be in contact with the yarn 20. The waxing device 70 is provided with a waxing portion 71 and a waxing portion 72. The waxing portion 71 is disposed on the front side of the winding machine unit 2. The waxing portion 72 is disposed on the back side of the winding machine unit 2. Figures 3-6 In the waxing device 70, the wax forming body W is disposed so as to be in contact with the yarn 20. The waxing device 70 is provided with a waxing portion 71 and a waxing portion 72. The waxing portion 71 is disposed on the front side of the winding machine unit 2. The waxing portion 72 is disposed on the back side of the winding machine unit 2.

[0056] As shown in FIG. 1, the waxing device 70 is provided with a waxing portion 71 and a waxing portion 72. The waxing portion 71 is disposed on the front side of the winding machine unit 2. The waxing portion 72 is disposed on the back side of the winding machine unit 2. Figures 3-6As shown, the waxing device 70 is a waxing device mounted to the winding machine unit 2. The waxing device 70 rotates a wax molding body W in a cylindrical shape about its axis, and contacts an end surface of the wax molding body W with the traveling yarn 20 while traversing it. Thus, the waxing device 70 waxes the yarn 20.

[0057] The wax molding body W is wax formed in a cylindrical shape. As the wax, various kinds of wax corresponding to the use or the gauge of the yarn 20, or the like can be used. For example, as the wax, natural wax such as beeswax, synthetic wax such as paraffin wax, or wax composed of a combination thereof can be used. Further, in the drawings, the wax molding body W is sometimes indicated by a dotted line for convenience of explanation.

[0058] The waxing device 70 includes a frame 71, a guide support member 73, a traverse guide 74, a wax support 75, a positioning portion 80, a first guide 81, a second guide 82, a third guide 83, and a cushion member 84.

[0059] The frame 71 is mounted to a frame (not shown) of the winding machine unit 2. The frame 71 is composed of a main body portion 71a, a downstream side plate 71b, and a side plate 71c.

[0060] The main body portion 71a is formed in a block shape, and is disposed so that its side wall is along the traveling direction of the yarn 20. A flange portion is provided on the X-direction one end side of the main body portion 71a so as to project toward the front side. The downstream side plate 71b is formed in a flat plate shape, and is disposed so that its thickness direction is along the traveling direction of the yarn 20. Further, in the drawings, the downstream side plate 71b is often indicated by a dotted line for convenience of explanation. The downstream side plate 71b is fixed to the face on the downstream side of the main body portion 71a by a screw or the like. A threaded hole 72c is provided in the downstream side plate 71b so as to penetrate along the traveling direction of the yarn 20.

[0061] The side plate 71c is formed in a flat plate shape, and is disposed so that its thickness direction is along the X-direction. The side plate 71c extends on the X-direction one end side of the downstream side plate 71b so as to be orthogonal to the downstream side plate 71b. The side plate 71c is fixed to the flange portion of the main body portion 71a by a screw or the like. The main body portion 71a and the side plate 71c are fixed to the frame (not shown) of the winding machine unit 2 by a screw or the like. Thus, the frame 71 is mounted to the winding machine unit 2.

[0062] The guide support member 73 supports the first guide 81, the second guide 82, and the positioning portion 80.

[0063] The guide support member 73 is fixed to the X-direction other end side of the main body portion 71a. The guide support member 73 is a bent plate-like member bent in a U shape opening in the X-direction as viewed from the front side. The guide support member 73 is composed of an upstream portion 73a, a downstream portion 73b, and a side portion 73c.

[0064] The upstream portion 73a and the downstream portion 73b are formed in a flat plate shape, and are arranged so that the thickness direction thereof is along the traveling direction of the yarn 20. A threaded hole 72a that penetrates along the traveling direction of the yarn 20 is provided in the upstream portion 73a. The upstream portion 73a is larger than the downstream portion 73b. The downstream portion 73b is arranged so as to oppose the upstream portion 73a at a position that is separated by a prescribed distance from the upstream portion 73a toward the downstream side. A threaded hole 72b that penetrates along the traveling direction of the yarn 20 is provided in the downstream portion 73b. The downstream portion 73b is arranged on the front surface side relative to the wax molded body W.

[0065] The side portion 73c is formed in a flat plate shape, and is arranged so that the thickness direction thereof is along the X direction. The side portion 73c links one end of the upstream portion 73a and one end of the downstream portion 73b in the X direction. The side portion 73c extends in a manner orthogonal to the upstream portion 73a and the downstream portion 73b. The side portion 73c is fixed to the side wall of the main body portion 71a by a screw N.

[0066] The traverse guide portion 74 guides the yarn 20 wound around the package 30 (refer to Figure 2 ) so as to form a prescribed traverse region P and traverse. The prescribed traverse region P is a movement plane of the yarn 20 formed by the traversing yarn 20. The prescribed traverse region P is an imaginary plane (refer to Figure 6 ) of triangular shape that takes the upstream side as the vertex (traverse center), takes the traveling direction of the yarn 20 as the height direction, and takes the X direction that is the traverse direction as the width direction. The traverse region is also called a traverse region or a traverse plane. The traverse guide portion 74 is composed of a hole portion 74a formed in the upstream portion 73a of the guide support member 73, and a slit portion 74b formed in the downstream side plate 71b. That is, the traverse guide portion 74 is fixedly provided relative to the frame 71.

[0067] The hole portion 74a passes through the traversing yarn 20 at the prescribed traverse region P. The hole portion 74a passes through the yarn 20 that traverses at the prescribed traverse region P at a position of a first traverse width on the traverse center side. The hole portion 74a is formed in the upstream portion 73a so as to communicate with an opening portion 74c that is open on the front surface side. The opening portion 74c forms a yarn passage that allows the yarn 20 to enter the hole portion 74a, and the like. In the present embodiment, the start point of the traverse region P is formed in the hole portion 74a.

[0068] The slit portion 74b extends along the X direction, and opposes the hole portion 74a in the traveling direction of the yarn 20. The slit portion 74b passes through the yarn 20 that traverses at the prescribed traverse region P. The slit portion 74b passes through the yarn 20 that traverses at the prescribed traverse region P at a position of a second traverse width that is larger than the first traverse width. The slit portion 74b is formed in the downstream portion 73b so as to communicate with an opening portion 74d that is open on the front surface side. The opening portion 74d forms a yarn passage that allows the yarn 20 to enter the slit portion 74b, and the like.

[0069] The wax supporting portion 75 supports the wax molded body W in such a manner that the wax molded body W reaches at least a part of the prescribed traverse region P of the yarn 20 (refer to Figure 6 ). The wax supporting portion 75 supports one end surface (end surface on the front side) of the wax molded body W so as to move toward the prescribed traverse region P at the time of normal take-up. The wax supporting portion 75 is constituted by a mounting shaft 76 and a pressing lever 77.

[0070] As shown in Figures 3-6 , the mounting shaft 76 is inserted into the cylindrical hole of the wax molded body W and is mounted so as to be able to rotate in synchronization with the wax molded body W. The mounting shaft 76 is disposed between the upstream portion 73a and the downstream portion 73b of the guide supporting member 73. The rear end portion of the mounting shaft 76 is mounted to a motor 78 that rotates and drives the mounting shaft 76. The motor 78 is fixed to a swing arm 79 described later. Thus, the mounting shaft 76 rotatably shaft supports the wax molded body W on the swing arm 79 described later.

[0071] The pressing lever 77 presses the wax molded body W mounted to the mounting shaft 76 toward the front side. The pressing lever 77 is disposed on the upstream side from the downstream side plate 71b. The pressing lever 77 has a swing shaft 77a provided on the base end side thereof and a pressing portion 77b provided on the front end side thereof.

[0072] The pressing lever 77 is configured so as to be able to swing about the swing shaft 77a. The swing shaft 77a is erected on the swing arm 79 described later and extends along the advancing direction of the yarn 20. A torsion coil spring, not shown, is mounted to the swing shaft 77a, and the pressing lever 77 is urged by the elastic force of the torsion coil spring, whereby the pressing portion 77b is urged toward the front side. Thus, the pressing lever 77 presses the flange-like portion Wa mounted to the rear end surface of the wax molded body W with the pressing portion 77b and presses the wax molded body W toward the front side with respect to the prescribed traverse region P.

[0073] The wax molded body W supported by the wax supporting portion 75 described above is located on the side opposite to the front side (back side) with respect to the prescribed traverse region P. That is, the prescribed traverse region P is located on the front side with respect to the wax molded body W. In the waxing device 70, the wax supporting portion 75 supports the wax molded body W in such a manner that one end surface of the wax molded body W faces the front side of the waxing device 70 and in such a manner that the one end surface of the wax molded body W contacts at least a part of the traverse region P of the yarn 20. The wax supporting portion 75 can also be rotatably moved with respect to the frame 71 about a rotation axis (not shown) that extends along the advancing direction of the yarn 20. That is, the waxing device 70 can also be provided with a rotationally openable and closable mechanism that makes the wax supporting portion 75 movable at the time of normal take-up and at the time of switching at the time of the replacement work.

[0074] A mounting shaft 76 and a motor 78 are attached to one end portion of the swing arm 79. Specifically, a standing plate portion 79a is provided at the one end portion of the swing arm 79 so as to stand up in a manner of being bent at the front side thereof. The standing plate portion 79a extends in a manner of protruding toward the downstream side beyond the downstream side plate 71b. The mounting shaft 76 is inserted through the standing plate portion 79a. The motor 78 connected to the mounting shaft 76 is fixed to the one end portion of the swing arm 79 in a state of abutting against the standing plate portion 79a. A presser bar 77 is attached to the other end portion of the swing arm 79. Specifically, a swing shaft 77a of the presser bar 77 is fixed to the other end portion of the swing arm 79. Thus, at the other end portion of the swing arm 79, the presser bar 77 is supported so as to be swingable about the swing shaft 77a.

[0075] The positioning portion 80 contacts the wax molded body W supported by the wax supporting portion 75 via a prescribed traverse region P, and performs positioning of the wax molded body W with respect to the yarn 20. The positioning portion 80 is disposed between the upstream portion 73a and the downstream portion 73b of the guide supporting member 73. The positioning portion 80 is fixed to the side portion 73c of the guide supporting member 73. The positioning portion 80 has an abutting supporting portion 80a, a connecting portion 80b, and three or more (here, three) abutting portions 80c.

[0076] The abutting supporting portion 80a is disposed at a position opposed to the end portion of the front side of the wax molded body W at the time of normal winding. One end portion of the connecting portion 80b is fixed to the side portion 73c of the guide supporting member 73, and the other end portion is fixed to the abutting supporting portion 80a. The connecting portion 80b supports the abutting supporting portion 80a. The positioning portion 80 is fixed to the main body portion 71a together with the side portion 73c of the guide supporting member 73 by means of a screw N.

[0077] The abutting portion 80c is provided to the abutting support portion 80a and abuts against the wax molded body W. The abutting portion 80c is provided to the back surface side of the abutting support portion 80a. The abutting portion 80c abuts against the end surface of the front surface side of the wax molded body W supported by the wax support portion 75 at the time of normal take-up. The abutting portion 80c is provided in three in a manner of sandwiching the traverse region P in the X direction and in a manner of sandwiching the mounting shaft 76 in the advancing direction of the yarn 20. The three abutting portions 80c are, for example, the same shape and abut against the end surface of the front surface side of the wax molded body W with the front end rounded. One abutting portion 80c is provided to the opening side of the guide support member 73 further than the traverse region P and is provided to the downstream side of the fixed position of the abutting support portion 80a and the connecting portion 80b. The other one abutting portion 80c is provided to the main body portion 71a side further than the traverse region P and is provided to the downstream side of the fixed position of the abutting support portion 80a and the connecting portion 80b. The other other abutting portion 80c is provided to the main body portion 71a side further than the traverse region P and is provided to the upstream side of the fixed position of the abutting support portion 80a and the connecting portion 80b. Thus, the wax molded body W is supported so that the end surface of the front surface side of the wax molded body W is along the plane formed by the end portions of the back surface sides of the respective abutting portions 80c. That is, the wax molded body W can be restrained from swinging to the front surface side and the back surface side by the pressure bar 77 and the abutting portion 80c.

[0078] The first guide portion 81, the second guide portion 82, and the third guide portion 83 are members that guide the yarn 20 and restrict the movement of the yarn 20. The first guide portion 81, the second guide portion 82, and the third guide portion 83 each have a first rectangular plate portion 81a, a second rectangular plate portion 82a, and a third rectangular plate portion 83a that set the advancing direction of the yarn 20 as the thickness direction and that include planar side surfaces along the traverse region P. In other words, the first guide portion 81, the second guide portion 82, and the third guide portion 83 are in the shape of rectangular plates having the above-described side surfaces. The respective side surfaces of the first guide portion 81, the second guide portion 82, and the third guide portion 83 here are along the plane passing through the end portions of the back surface sides of the three abutting portions 80c. The first guide portion 81, the second guide portion 82, and the third guide portion 83 here are in straight line shapes along the X direction in a case where viewed from the advancing direction of the yarn 20 without the X direction of a part thereof protruding or being recessed to the front surface side or the back surface side.

[0079] The first guide portion 81 is provided to either of the upstream side and the downstream side of the advancing direction of the yarn 20 with respect to the wax molded body W. The first guide portion 81 is provided between the second guide portion 82 and the third guide portion 83 in the advancing direction of the yarn 20. In the present embodiment, one first guide portion 81 is provided to the downstream side of the advancing direction of the yarn 20 with respect to the wax molded body W and the upstream side of the third guide portion 83 from the second guide portion 82. The first guide portion 81 is provided to the upper surface of the downstream portion 73b of the guide support member 73.

[0080] The first guide portion 81 is provided on the front surface side (the side opposite to the wax molded body W side) with respect to the yarn passage of the yarn 20, and restricts movement of the yarn 20 to the front surface side. That is, the first guide portion 81 is provided on the front surface side with respect to the predetermined traverse region P. The first guide portion 81 (the first rectangular plate portion 81a) can contact the yarn 20 on the side surface of the back surface side, and guide the yarn 20. The first guide portion 81 is in slight contact (to the extent that the yarn surface is slightly contacted) with the yarn 20 when the yarn 20 travels. The side surface of the back surface side of the first guide portion 81 can also have a rounded corner at the boundary with the upstream side face and the downstream side face. The side surface of the back surface side of the first guide portion 81 is located within the narrow slit portion 74b of the traverse guide portion 74, as viewed from the downstream side. The side surface of the back surface side of the first guide portion 81 protrudes more toward the back surface side than the side surface of the back surface side of the downstream portion 73b. The first guide portion 81 is configured so that the traverse region P is located in the central portion of the first guide portion 81 in the X direction. A threaded hole 81b is provided in the first guide portion 81 so as to pass through in the traveling direction of the yarn 20. The first guide portion 81 is configured so as to communicate the threaded hole 81b with the threaded hole 72b of the downstream portion 73b. A screw N inserted into the first guide portion 81 from the downstream side is screwed into the threaded hole 81b of the first guide portion 81 and the threaded hole 72b of the downstream portion 73b. Thus, the first guide portion 81 is fixedly provided to the guide support member 73.

[0081] The second guide portion 82 is provided on the upstream side with respect to the traveling direction of the yarn 20 with respect to the wax molded body W. The second guide portion 82 is provided at the start of the predetermined traverse region P. The second guide portion is provided on the back surface side (the wax molded body W side) with respect to the yarn passage of the yarn 20, and restricts movement of the yarn 20 to the back surface side. The second guide portion 82 (the second rectangular plate portion 82a) can contact the yarn 20 on the side surface of the front surface side, and guide the yarn 20. The side surface of the front surface side of the second guide portion 82 can also have a rounded corner at the boundary with the upstream side face and the downstream side face. The side surface of the front surface side of the second guide portion 82 is located within the hole portion 74a of the traverse guide portion 74, as viewed from the upstream side. The second guide portion 82 is provided at a position that does not oppose the downstream portion 73b in the traveling direction of the yarn 20. The second guide portion 82 is configured so that the hole portion 74a is located in the central portion of the second guide portion 82 in the X direction.

[0082] The second guide portion 82 is provided on the upper surface of the upstream portion 73a of the guide support member 73. A threaded hole 82b is provided in the second guide portion 82 so as to pass through in the traveling direction of the yarn 20. The second guide portion 82 is configured so as to communicate the threaded hole 82b with the threaded hole 72a of the upstream portion 73a. A screw N inserted into the second guide portion 82 from the upstream side is screwed into the threaded hole 82b of the second guide portion 82 and the threaded hole 72a of the upstream portion 73a. Thus, the second guide portion 82 is fixedly provided to the guide support member 73.

[0083] The third guide portion 83 is provided on the downstream side of the traveling direction of the yarn 20 with respect to the wax molded body W. The third guide portion 83 is provided on the back surface side with respect to the yarn passage of the yarn 20, and restricts the movement of the yarn 20 to the back surface side. The third guide portion 83 (the third rectangular plate portion 83a) can contact the side surface of the front surface side thereof with the yarn 20, and guide the yarn 20. The side surface of the front surface side of the third guide portion 83 and the boundary portion of the upstream side face and the downstream side face can also be rounded. The side surface of the front surface side of the third guide portion 83 is located within the narrow slit portion 74b of the traverse guide portion 74, as viewed from the downstream side. In the present embodiment, the end portion of the front surface side of the third guide portion 83 is disposed on the front surface side with respect to the end portion of the front surface side of the wax molded body W, as viewed from the traveling direction of the yarn 20. The third guide portion 83 is provided at a position opposed to the upstream portion 73a and the second guide portion 82 in the traveling direction of the yarn 20. The third guide portion 83 is disposed so that the traverse region P is located at the central portion of the third guide portion 83 in the X direction.

[0084] The third guide portion 83 is provided on the lower surface of the downstream side plate 71b of the frame body 71. The third guide portion 83 is provided with a threaded hole 83b that penetrates along the traveling direction of the yarn 20. The third guide portion 83 is disposed so as to communicate the threaded hole 83b with the threaded hole 72c of the downstream side plate 71b. A screw N inserted from the upstream side with respect to the third guide portion 83 is screwed with the threaded hole 83b of the third guide portion 83 and the threaded hole 72c of the downstream side plate 71b. Thus, the third guide portion 83 is fixedly provided to the frame body 71.

[0085] The widths of the respective guide portions 81, 82, 83 in the X direction are made longer toward the downstream side from the upstream side. That is, in the present embodiment, the widths of the second guide portion 82, the first guide portion 81, and the third guide portion 83 in the X direction are sequentially made longer. Thus, the yarn 20 can be appropriately guided even on the downstream side where the width of the traverse region P is widened.

[0086] The positioning portion 80 positions the wax molded body W in such a manner that the end portion (for example, the end face) of the front surface side of the wax molded body W disposed (contacted) to the traverse region P is located between the first guide portion 81 and the second guide portion 82, as viewed from the traveling direction of the yarn 20. At this time, the first guide portion 81 and the second guide portion 82 are disposed in such a manner that the yarn passage of the yarn 20 between the first guide portion 81 and the second guide portion 82 does not contact the mounting shaft 76. The yarn 20 is restricted by the first guide portion 81 and the second guide portion 82, so by the above-described disposition, the yarn 20 can appropriately contact the wax molded body W halfway from the second guide portion 82 to the first guide portion 81.

[0087] In the front-rear direction of the winder unit 2 (direction perpendicular to the traversing region P), the distance between the first guide portion 81 and the second guide portion 82 is greater than the distance between the first guide portion 81 and the third guide portion 83. On the downstream side of the second guide portion 82, in addition to being able to restrict the movement of the yarn 20 to the front side by the first guide portion 81, the third guide portion 83 is able to appropriately restrict the movement of the yarn 20 to the back side in such a manner that the yarn 20 does not excessively move to the back side. Further, in the direction perpendicular to the traversing region P, the first guide portion 81 is disposed in close proximity to the third guide portion 83.

[0088] The cushioning member 84 absorbs (cushions) the impact resulting from the contact of the upright portion 79a of the swing arm 79 with the downstream side plate 71b at the time of normal take-up or the time of the changing operation of the motor 78. As the cushioning member 84, for example, a resin member can be used. The cushioning member 84 is disposed to the downstream side plate 71b in such a manner that it is sandwiched between the downstream side plate 71b and the upright portion 79a at the time of normal take-up. According to the cushioning member 84, the sound and damage resulting from the contact of the upright portion 79a with the downstream side plate 71b can be suppressed.

[0089] Next, the waxing of the waxing device 70 will be described.

[0090] For example, in the present embodiment, as shown in Figs. 9 and 10, the end surface of the wax molding W disposed on the front side of the mounting shaft 76 presses and comes into contact with the traversing region P of the yarn 20, and the wax is attached to the yarn 20. At this time, the three abutting portions 80c of the positioning portion 80 abut against the end surface of the front side of the wax molding W. As shown in Fig. 10, the yarn 20 traversing in the traversing region P in the hole portion 74a is restricted from moving to the back side by the second guide portion 82. The yarn 20 traversing in the traversing region P in the narrow slit portion 74b is restricted from moving to the back side by the third guide portion 83. Further, as shown in Fig. 9, the waxing device 70 of the present embodiment is configured such that the first guide portion 81 is disposed on the front side of the traversing region P of the yarn 20. Figure 5 and Figure 6 As shown in Figs. 9 and 10, the end surface of the wax molding W disposed on the front side of the mounting shaft 76 presses and comes into contact with the traversing region P of the yarn 20, and the wax is attached to the yarn 20. At this time, the three abutting portions 80c of the positioning portion 80 abut against the end surface of the front side of the wax molding W. As shown in Fig. 10, the yarn 20 traversing in the traversing region P in the hole portion 74a is restricted from moving to the back side by the second guide portion 82. The yarn 20 traversing in the traversing region P in the narrow slit portion 74b is restricted from moving to the back side by the third guide portion 83. Further, as shown in Fig. 9, the waxing device 70 of the present embodiment is configured such that the first guide portion 81 is disposed on the front side of the traversing region P of the yarn 20. Figure 7 As shown in Fig. 10, the yarn 20 traversing in the traversing region P in the hole portion 74a is restricted from moving to the back side by the second guide portion 82. The yarn 20 traversing in the traversing region P in the narrow slit portion 74b is restricted from moving to the back side by the third guide portion 83. Further, as shown in Fig. 9, the waxing device 70 of the present embodiment is configured such that the first guide portion 81 is disposed on the front side of the traversing region P of the yarn 20. Figure 7 As shown in Fig. 9, the waxing device 70 of the present embodiment is configured such that the first guide portion 81 is disposed on the front side of the traversing region P of the yarn 20.

[0091] Here, in the present embodiment, by disposing the first guide portion 81 to the guide support member 73, the movement of the yarn 20 to the front side is restricted. Therefore, compared to the case where the first guide portion 81 is not disposed, the yarn passage of the yarn 20 can be positioned on the back side. That is, by disposing the first guide portion 81 on the front side of the traversing region P, the yarn 20 can be prevented from escaping to the front side. Thus, the yarn 20 is appropriately brought into contact with the wax molding W during the travel of the yarn 20 from the second guide portion 82 to the first guide portion 81 positioned on the downstream side, and thereby an appropriate amount of wax is attached to the yarn 20. Further, the yarn 20 can not come into contact with the third guide portion 83 positioned on the downstream side of the first guide portion 81.

[0092] In the above, the back surface side corresponds to the side of the wax molded body W, and the front surface side corresponds to the opposite side of the wax molded body W. The side of the wax molded body W is the side on which the wax molded body W exists in the case where the wax molded body W is attached to the attachment shaft 76, and does not depend on whether the wax molded body W is actually attached.

[0093] In the above, in the present embodiment of the waxing device 70, and the winding machine unit 2 and the automatic winding machine 1 provided with the same, the movement of the yarn 20 to the back surface side (the side opposite to the side of the wax molded body W) is restricted by the first guide portion 81, and the movement of the yarn 20 to the front surface side (the side of the wax molded body) is restricted by the second guide portion 82 and the third guide portion 83, so that the position of the yarn 20 with respect to the wax molded body W can be stabilized. Thus, the yarn 20 can be brought into appropriate contact with the wax molded body W. Therefore, the waxing device 70, and the winding machine unit 2 and the automatic winding machine 1 provided with the same can stabilize the amount of wax consumed. The case where the yarn 20 is pressed against the wax molded body W and floats to the front surface side can be suppressed, the front and back positions of the yarn 20 can be stabilized, and the influence of the tension variation and the vibration of the yarn 20 can be suppressed. In addition, for example, the damage of the yarn 20 to the wax molded body W and the like can be suppressed by the second guide portion 82 and the third guide portion 83. Also, for example, when the yarn 20 is not in contact with the wax molded body W, the case where the yarn 20 moves greatly to the back surface side (the side of the wax molded body W) can be suppressed by the third guide portion 83.

[0094] In the waxing device 70, the first guide portion 81 has the first rectangular plate portion 81a that sets the traveling direction of the yarn 20 to the thickness direction and includes a planar side surface along the traverse region P. Here, in the case where a part of the first guide portion 81 protrudes to the front surface side as viewed from the traveling direction of the yarn 20, although the position of the yarn 20 with respect to the wax molded body W can be adjusted, the position of the yarn 20 with respect to the wax molded body W is not stabilized in the traveling of the yarn 20, and the amount of wax applied to the yarn 20 is not stabilized. According to the structure of the present embodiment, the first guide portion 81 has the planar side surface along the traverse region P, so that the movement of the yarn 20 to the front surface side can be restricted. Therefore, the second guide portion 82 can stabilize the position of the yarn 20 with respect to the wax molded body W by a simple structure, and the precision of the position of the yarn 20 can be improved.

[0095] In the waxing device 70, the second guide portion 82 has a second rectangular plate portion 82a that sets the traveling direction of the yarn 20 to the thickness direction and includes a planar side surface along the traverse region P. Here, in a case where a part of the second guide portion 82 protrudes to the front surface side as viewed from the traveling direction of the yarn 20, although it is possible to adjust the position of the yarn 20 and the wax molded body W, the position of the yarn 20 and the wax molded body W is unstable in the traveling of the yarn 20, and the amount of wax applied to the yarn 20 is unstable. According to the structure of the present embodiment, the second guide portion 82 has a planar side surface along the traverse region P, so it is possible to restrict the movement of the yarn 20 to the back surface side. Thus, the second guide portion 82 can stabilize the position of the yarn 20 with respect to the wax molded body W by a simple structure, and can improve the accuracy of the position of the yarn 20.

[0096] In the waxing device 70, the third guide portion 83 has a third rectangular plate portion 83a that sets the traveling direction of the yarn 20 to the thickness direction and includes a planar side surface along the traverse region P. According to this structure, it is possible to stabilize the position of the yarn with respect to the wax molded body by a simple structure, and can improve the accuracy of the position of the yarn. Here, in a case where a part of the third guide portion 83 protrudes to the front surface side as viewed from the traveling direction of the yarn 20, although it is possible to adjust the position of the yarn 20 and the wax molded body W, the position of the yarn 20 and the wax molded body W is unstable in the traveling of the yarn 20, and the amount of wax applied to the yarn 20 is unstable. According to the structure of the present embodiment, the third guide portion 83 has a planar side surface along the traverse region P, so it is possible to restrict the movement of the yarn 20 to the back surface side. Thus, the third guide portion 83 can easily stabilize the position of the yarn 20 with respect to the wax molded body W by a simple structure, and can improve the accuracy of the position of the yarn 20.

[0097] The waxing device 70 has a guide support member 73 that is fixed to the frame 71 and supports the first guide portion 81 and the second guide portion 82. According to this structure, it is possible to fix the first guide portion 81 and the second guide portion 82 together to the frame 71 via the guide support member 73, and to stably integrally arrange the first guide portion 81 and the second guide portion 82. In addition, the frame 71 is mounted to the frame of the winding machine unit 2, so it is possible to fix the first guide portion 81 and the second guide portion 82 to the frame of the winding machine unit 2 via the frame 71 and the guide support member 73.

[0098] The waxing device 70 has a positioning portion 80 having three or more abutting portions 80c that abut against the wax molded body W and performs positioning of the wax molded body W, and the positioning portion 80 is supported by the guide support member 73. Here, in the case of the existing waxing device having two abutting portions that abut against the wax molded body W, the wax molded body W can possibly swing with a line joining the two abutting portions as a boundary. In the case of the existing waxing device having one abutting portion that abuts against the wax molded body W, the wax molded body W can possibly swing with the one abutting portion as a starting point. According to the structure of the present embodiment, by the three or more abutting portions 80c abutting against the wax molded body W, the wax molded body W can be surface-supported, and the positioning accuracy of the positioning portion 80 against the wax molded body W can be ensured. The case where the wax molded body W loosens and the wax consumption amount becomes unstable can be suppressed. In addition, the first guide portion 81, the second guide portion 82, and the positioning portion 80 can be fixed to the frame 71 together via the guide support member 73, and the first guide portion 81, the second guide portion 82, and the positioning portion 80 can be stably configured integrally.

[0099] In the waxing device 70, the positioning portion 80 positions the wax molded body W so that the end portion of the (contacting) wax molded body W in the traverse region P is located between the first guide portion 81 and the second guide portion 82, as viewed from the traveling direction of the yarn 20. For example, the wax molded body W is located in the yarn passage of the yarn 20 that travels from the first guide portion 81 toward the downstream side from the second guide portion 82. According to this structure, the functions of the first guide portion 81 and the second guide portion 82 can be more effectively exerted, and the yarn 20 and the wax molded body W can be brought into appropriate contact.

[0100] For the waxing device 70, in the direction perpendicular to the traverse region P, the distance between the first guide portion 81 and the second guide portion 82 is greater than the distance between the first guide portion 81 and the third guide portion 83. According to this structure, in the case where the waxing device 70 has the first guide portion 81, the second guide portion 82, and the third guide portion 83, the respective functions of these first guide portion 81, the second guide portion 82, and the third guide portion 83 can be effectively exerted. Specifically, according to this structure, in the traveling direction of the yarn 20, the movement of the yarn 20 can be appropriately restricted on the upstream side and the downstream side of the wax molded body W. In the present embodiment, a position where the yarn 20 and the wax molded body W are brought into appropriate contact can be ensured between the first guide portion 81 and the second guide portion 82, and the third guide portion 83 can appropriately restrict the movement of the yarn 20 toward the back surface side on the downstream side of the first guide portion 81.

[0101] In the waxing device 70, the first guide portion 81 is disposed in proximity to the upstream side of the third guide portion 83. According to this structure, by bringing the first guide portion 81 in proximity to the third guide portion 83, it is possible to suppress the swing of the yarn 20 on the downstream side of the waxed body W, and it is possible to appropriately restrict the movement of the yarn 20 in the direction perpendicular to the traverse region P.

[0102] In the waxing device 70, the wax support portion 75 supports the waxed body W in such a manner that the end surface of the waxed body W faces the front surface side of the waxing device 70, and the end surface of the waxed body W contacts at least a portion of the traverse region P of the yarn 20. According to this structure, even in the case where the end surface of the waxed body W that contacts a portion of the traverse region P of the yarn 20 faces the front surface side, it is possible to appropriately contact the yarn 20 with the waxed body W.

[0103] In the above, the embodiments of the present application have been described, but the present application is not limited to the above-described embodiments.

[0104] In the above-described embodiments, the first guide portion 81 is disposed on the downstream side of the waxed body W, but is not limited thereto. The first guide portion 81 can be disposed on either of the upstream side and the downstream side with respect to the yarn travel direction of the waxed body W. In the above-described embodiments, the positional relationship of the first guide portion 81, the second guide portion 82, and the third guide portion 83 in the front-rear direction (the direction perpendicular to the traverse region P) of the winding machine unit 2 is not particularly limited. If the first guide portion 81 is disposed on the front surface side than the yarn passage of the yarn 20, and the second guide portion 82 and the third guide portion 83 are disposed on the back surface side than the yarn passage of the yarn 20, the positional relationship can also be various relationships.

[0105] In the above-described embodiments, the guide support member 73 can not support both the first guide portion 81 and the second guide portion 82.
