An operator of the automatic winder 1 can manage a plurality of winder units 2 in a centralized manner by appropriately operating the machine control device 3. The machine control device 3 controls the operations of the yarn feeding bobbin supply device 4 and the doffing device 5.

  The yarn supplying bobbin supplying device 4 sets the yarn supplying bobbins 21 one by one on the transport tray 26. The yarn supplying bobbin supply device 4 supplies the yarn supplying bobbin 21 set on the transport tray 26 to each of the plurality of winder units 2.

  The doffing device 5 travels to the position of the winder unit 2 when the package 30 becomes full in the winder unit 2 (a state in which a predetermined amount of yarn 20 is wound), Remove. The doffing device 5 sets an empty winding bobbin 22 to the winder unit 2 from which the package 30 has been removed.

  Next, the configuration of the winder unit 2 will be described. As shown in FIG. 2, the winder unit 2 includes a yarn supplying unit 6, a yarn accumulating device 18, a package forming unit 8, and a wax applying device 70. In the winder unit 2, the yarn 20 of the yarn feeding bobbin 21 of the yarn feeding unit 6 is unwound, the unwound yarn 20 is temporarily stored by the yarn storage device 18, and then wound around the winding bobbin 22 to form a package 30. To do.

  The yarn feeding section 6 is configured to support the yarn feeding bobbin 21 set on the transport tray 26 at a predetermined position and to unwind the yarn 20 from the yarn feeding bobbin 21. When all the yarns 20 are unwound from the yarn supplying bobbin 21, the yarn supplying unit 6 discharges the empty yarn supplying bobbin 21, and supplies a new yarn supplying bobbin 21 from the yarn supplying bobbin supplying device 4. receive.

  The yarn accumulating device 18 is disposed between the yarn supplying unit 6 and the package forming unit 8. The yarn storage device 18 is provided at a position upstream of the wax applying device 70 in the traveling direction of the yarn 20. The yarn storage device 18 winds and temporarily stores the yarn 20 unwound by the yarn supplying unit 6. The yarn storage device 18 supplies the stored yarn 20 to the package forming unit 8. The yarn accumulating device 18 includes a yarn accumulating roller 32 that can wind the yarn 20 and a roller driving motor 33 that rotationally drives the yarn accumulating roller 32. The roller drive motor 33 rotates the yarn accumulating roller 32 in the direction of winding the yarn 20 from the yarn supplying unit 6. The roller drive motor 33 can also rotate the yarn accumulating roller 32 in a direction opposite to the winding direction.

  The package forming unit 8 includes a cradle 23 configured to be capable of mounting the winding bobbin 22 and a traverse drum 24 that drives the winding bobbin 22 while traversing the yarn 20. The package forming unit 8 constitutes a winding unit. The cradle 23 rotatably supports the take-up bobbin 22 (or the package 30). The cradle 23 is configured such that the outer peripheral surface of the supporting package 30 can contact the outer peripheral surface of the traverse drum 24.

  The traverse drum 24 is rotationally driven by an unillustrated drive source (such as an electric motor) and rotates while being in contact with the winding bobbin 22 or the outer peripheral surface of the package 30, thereby rotating the winding bobbin 22 in a driven manner. As a result, the yarn 20 stored in the yarn storage device 18 can be unwound and pulled out and taken up on the take-up bobbin 22. A traverse groove (not shown) is formed on the outer peripheral surface of the traverse drum 24, and the traverse of the yarn 20 with a predetermined width can be performed by the traverse groove. With the above configuration, the package 20 having a predetermined shape can be formed by winding the yarn 20 around the winding bobbin 22 while traversing.

  The wax applying device 70 is disposed between the yarn accumulating device 18 and the package forming unit 8. The wax applying device 70 applies wax to the yarn 20 that travels from the yarn storage device 18 toward the package forming unit 8. A specific configuration of the wax applying device 70 will be described later.

  The winder unit 2 includes various devices in a yarn traveling path from the yarn supplying unit 6 to the package forming unit 8 via the yarn accumulating device 18. Specifically, on the yarn path (yarn traveling path) of the yarn 20, the unwinding assisting device 10 and the upstream yarn blowing unit are sequentially arranged from the upstream yarn supplying unit 6 side toward the downstream yarn storage device 18 side. 11, the second catching unit 12, the yarn joining device 13, the first catching unit 14, the tension applying unit 15, the cutter 16, the yarn monitoring device 17, and the downstream yarn blowing unit 48. ing.

  The unwinding assisting device 10 brings the movable member 27 into contact with the balloon formed on the upper portion of the yarn supplying bobbin 21 by swinging the yarn 20 to be unwound from the yarn supplying bobbin 21 so that the size of the balloon is appropriately set. By controlling this, the unwinding of the yarn 20 is assisted.

  The upstream yarn blowing section 11 is an air soccer device disposed at a position close to the unwinding assisting device 10 on the downstream side of the unwinding assisting device 10. The upstream yarn blowing section 11 forms an air flow that blows the yarn 20 to the first catching section 14 by ejecting compressed air. Therefore, for example, when yarn breakage occurs, the upstream yarn blowing section 11 operates to blow the yarn end on the yarn feeding bobbin 21 side toward the yarn joining device 13 side.

  When the new yarn supplying bobbin 21 is supplied to the yarn supplying unit 6, the yarn end is blown to a position where the yarn end can be blown to the yarn joining device 13 by the upstream yarn blowing unit 11. An auxiliary blowing part 28 is provided.

  The auxiliary blow-feed unit 28 blows the compressed air into the hollow conveyance tray 26 and the yarn feeding bobbin 21, so that the yarn 20 of the yarn feeding bobbin 21 is put on the tip of the yarn feeding bobbin 21. An air flow to be blown to the upstream yarn blowing section 11 side is formed. When the newly supplied yarn supplying bobbin 21 is supported by the yarn supplying unit 6, the auxiliary blow feeding unit 28 and the upstream yarn blowing unit 11 operate in conjunction with each other, so that the yarn end on the yarn feeding bobbin 21 side is moved. The yarn can be reliably sent toward the yarn joining device 13 side.

  The second catching portion 12 is disposed on the upstream side of the yarn joining device 13. The second catching unit 12 is connected to a suction flow generation source (not shown), and generates a suction air flow at the time of yarn joining to suck and catch the yarn 20 on the yarn storage device 18 side.

  The yarn joining device 13 performs yarn joining of the divided yarn 20. The yarn joining device 13 is used when the yarn monitoring device 17 detects a yarn defect and cuts the yarn 20 with the cutter 16, when the yarn 20 being unwound from the yarn feeding bobbin 21 is cut, or when the yarn is fed. When the yarn 20 between the yarn supplying bobbin 21 and the yarn accumulating device 18 is divided, such as when the bobbin 21 is replaced, the yarn 20 on the yarn supplying bobbin 21 side and the yarn accumulating device 18 are separated. The side yarn 20 is spliced. The yarn joining device 13 is arranged at a position slightly retracted from the yarn path. The yarn joining device 13 can connect the introduced yarn ends to bring the yarn 20 into a continuous state. As the yarn joining device 13, a device using a fluid such as compressed air or a mechanical device can be used.

  The first catching portion 14 is disposed at a position close to the yarn joining device 13 on the downstream side of the yarn joining device 13. The first capturing portion 14 is configured as a cylindrical member that is connected to a negative pressure source (not shown) and has an opening at the tip. The first capturing unit 14 includes an advance / retreat driving unit 47. The advance / retreat drive unit 47 advances and retracts the first capturing unit 14 with respect to the yarn path.

  When the first catching portion 14 is approaching the yarn path, the first catching portion 14 generates a suction air flow on the tip side thereof, and thereby the yarn end from the yarn feeding bobbin 21 blown by the upstream yarn blowing portion 11. Aspirate and capture. When the yarn 20 is cut by the cutter 16, the first catching unit 14 sucks and catches the yarn end of the cut yarn 20 on the yarn feeding bobbin 21 side. Further, the first catching portion 14 may be configured to suck and remove the fluff adhering to the traveling yarn 20 by generating a suction air flow on the tip side thereof. The first catching portion 14 can introduce the yarn end into the yarn joining device 13 by retreating from the yarn path in a state where the yarn end of the yarn feeding bobbin 21 is caught.

  The tension applying unit 15 applies a predetermined tension to the traveling yarn 20. The tension applying unit 15 is configured as a gate type in which movable comb teeth are arranged with respect to fixed comb teeth, and applies a predetermined resistance by running the thread 20 between the comb teeth. The movable comb teeth are configured to be movable by, for example, a solenoid so that the comb teeth are engaged or released. Thereby, the tension applying unit 15 can adjust the tension applied to the yarn 20. The configuration of the tension applying unit 15 is not particularly limited, and may be, for example, a disk type tension applying unit.

  The yarn monitoring device 17 detects a yarn defect such as a slab or foreign matter by monitoring the thickness of the yarn 20 with an appropriate sensor. A cutter 16 is disposed at a position close to the yarn monitoring device 17 on the upstream side of the yarn monitoring device 17. The cutter 16 cuts the yarn 20 immediately when the yarn monitoring device 17 detects a yarn defect.

  The cutter 16 and the yarn monitoring device 17 are accommodated in a common housing 19. The housing 19 that houses the yarn monitoring device 17 is disposed at a position close to the tension applying unit 15 on the downstream side of the tension applying unit 15. With this configuration, since the yarn monitoring device 17 monitors the vicinity of the portion where the traveling yarn 20 is held (guided) by the tension applying unit 15, the yarn 20 in the monitoring portion is less likely to be shaken, and the yarn monitoring device. The accuracy with which 17 detects the defect of the yarn 20 can be further increased.

  The downstream yarn blowing section 48 is an air soccer device arranged at a position close to the yarn storage device 18 on the upstream side of the yarn storage device 18. The downstream yarn blowing section 48 blows off the yarn end on the yarn storage device 18 side by blowing out compressed air, thereby forming an air flow that is sent to the second catching section 12. Specifically, the downstream yarn blowing section 48 includes a thin cylindrical guide member that can pass the yarn 20 therein, and a yarn guide member 60 that is a curved cylindrical member. . An outlet for the yarn 20 is formed at one end of the guide member. The yarn guide member 60 is provided so as to be close to the outlet of the downstream yarn blowing section 48. Openings are formed at both ends of the yarn guide member 60 in the longitudinal direction.

  The yarn guide member 60 is arranged in a state where the opening on one end side thereof is opposed to the outlet of the downstream yarn blowing section 48 and the opening on the other end side is opposed to the second catching portion 12. A guide path is formed inside the yarn guide member 60. The guide path connects openings at both ends of the yarn guide member 60 so as to bypass the yarn monitoring device 17, the tension applying unit 15, the yarn joining device 13, and the like. The downstream yarn blowing section 48, the yarn guide member 60, and the second catching portion 12 constitute a storage-side yarn end catching device 50.

  The downstream yarn blowing section 48 captures the yarn 20 on the yarn storage device 18 side and guides the yarn guide member 60 when the yarn 20 is divided between the yarn supply bobbin 21 and the yarn storage device 18. And the yarn 20 is pulled out along the guide path and is captured by the second capturing unit 12. Since the thread guide member 60 is formed with a not-shown penetrating slit over the entire length, the thread 20 is pulled from the inside of the thread guide member 60 in a state where the thread 20 is captured by the second capturing portion 12. Can be pulled out. As described above, the yarn 20 on the yarn storage device 18 side can be blown by the downstream yarn blowing section 48 and guided toward the yarn joining device 13 side.

  Each winder unit 2 includes a control unit 25. The control unit 25 includes hardware such as an unillustrated CPU, ROM, and RAM. The RAM stores software such as a control program. The control unit 25 controls each configuration of the winder unit 2 in cooperation with hardware and software. The control unit 25 is configured to be able to communicate with the machine base control device 3. Thereby, operation | movement of the several winder unit 2 with which the automatic winder 1 was equipped can be managed centrally in the stand control apparatus 3. FIG.

In the following description, “front side” and “back side” mean the front side (front side) and the back side (rear side) of the winder unit 2, respectively. The “X direction” corresponds to the traverse direction of the yarn 20.

  3 to 6 show the state of the wax applying device 70 during normal winding. The normal winding time is a state in which the yarn 20 is continuous between the yarn supplying bobbin 21 and the package 30, and is a time of wax application in which wax is applied to the traveling yarn 20. 7 and 8 show the state of the wax applying device 70 during the replacement work. The replacement operation is a state in which the yarn 20 is continuous between the yarn supplying bobbin 21 and the package 30 and is a time of replacement (attachment and / or removal) of the wax molded body W. During the replacement operation, the wax molded body W is exposed to the outside of the casing 72 so that the wax molded body W can be replaced.

  As shown in FIGS. 3 to 6, the wax applying device 70 is a wax applying device attached to the winder unit 2. The wax applicator 70 rotates the cylindrical wax molded body W around its axis and presses one end surface of the wax molded body W against the yarn 20 that travels while being traversed. Thereby, the wax applying device 70 applies wax to the yarn 20.

  The wax molded body W is a wax molded into a cylindrical shape. As the wax, various waxes corresponding to the use or specification of the yarn 20 are used. For example, natural wax such as wax, synthetic wax such as paraffin wax, or a combination of these can be used as the wax.

  The holding lever 78 is configured to be swingable about a swing shaft 78a. The swing shaft 78a is erected on a swing arm 84, which will be described later, and extends along the traveling direction of the yarn 20. A torsion coil spring (not shown) is attached to the swing shaft 78a, and the pressing lever 78 is biased by the elastic force of the torsion coil spring, so that the pressing portion 78b is biased toward the front side. The Accordingly, the pressing lever 78 presses the hook-shaped member Wa attached to the rear end surface of the wax molded body W with the pressing portion 78b, and directs the wax molded body W toward the front side with respect to the predetermined traversing region P. Press.

  A swing regulating pin 78c is erected on the end of the pressing lever 78 opposite to the pressing portion 78b. The swing restricting pin 78c is biased rearward by the pressing lever 78 being biased by the elastic force of the torsion coil spring attached to the swing shaft 78a. The swing restricting pin 78c restricts swinging of the pressing lever 78 by engaging with an engaging piece 80 provided on the inner surface of the downstream plate 72b (the surface on the upstream plate 72a side) during replacement work ( Details will be described later).

  The wax molded body W supported by the wax support portion 76 as described above is located on the opposite side (rear side) with respect to the predetermined traverse region P. That is, the predetermined traverse region P is located on the front side with respect to the wax molded body W. The wax support portion 76 is attached to the housing 72 via a moving mechanism 82 configured to be movable in a direction away from a predetermined traversing region P in order to attach and detach the wax molded body W.

  The moving mechanism 82 has a rotation shaft 83 extending along the traveling direction of the yarn 20, and rotates the wax support portion 76 relative to the housing 72 around the rotation shaft 83 to open and close the wax support portion 76. That is, the moving mechanism 82 is between the state of the wax applying device 70 during normal winding (see FIGS. 3 to 6) and the state of the wax applying device 70 during replacement work (see FIGS. 7 and 8). This is a rotary opening / closing mechanism that moves the wax support 76. The moving mechanism 82 here realizes a rearward opening type wax applying device 70 that swings and opens the wax support portion 76 to the back side.

  The moving mechanism 82 has a swing arm 84 configured to be rotatable (swingable) about a rotation shaft 83. The moving mechanism 82 rotates (swings) the swing arm 84 about the rotation shaft 83, thereby rotating the wax support 76 attached to the swing arm 84 relative to the casing 72 (swing). Move).

  The rotating shaft 83 is disposed between the upstream plate 72a and the downstream plate 72b, and is fixed to the downstream plate 72b with screws or the like. The swing arm 84 is disposed on the back side of the wax applying device 70. The swing arm 84 has a substantially L-shaped flat plate shape in which the thickness direction is the traveling direction of the yarn 20. The swing arm 84 has a rotating shaft 83 attached to a portion (an L-shaped bent portion) between one end portion and the other end portion thereof.

  An attachment shaft 77 and a motor 79 are attached to one end of the swing arm 84. Specifically, an upright plate portion 84a is provided at one end of the swing arm 84 so that the front side of the swing arm 84 is bent. The standing plate portion 84a extends beyond the downstream plate 72b so as to protrude downstream. A mounting shaft 77 is inserted through the upright plate portion 84a. The motor 79 connected to the mounting shaft 77 is fixed to one end portion of the swing arm 84 in contact with the upright plate portion 84a. A pressing lever 78 is attached to the other end of the swing arm 84. Specifically, the swing shaft 78 a of the pressing lever 78 is fixed to the other end of the swing arm 84. As a result, the holding lever 78 is supported at the other end of the swing arm 84 so as to be swingable about the swing shaft 78a.

  The lock mechanism 86 restricts the moving mechanism 82 so that the wax support portion 76 does not move with a force equal to or less than a predetermined force set during normal winding and replacement. Here, the lock mechanism 86 locks the operation of the swing arm 84 so that the swing arm 84 does not swing even if a force equal to or less than a predetermined force is applied to the swing arm 84. The lock mechanism 86 includes a lock pin 87, a cam 88, a lock shaft 89, a lock arm 90, and a torsion coil spring 91.

  The lock pin 87 is formed in a cylindrical shape whose axial direction is the traveling direction of the yarn 20. The lock pin 87 is erected on the other end of the swing arm 84. The cam 88 is formed in a cylindrical shape whose axial direction is the traveling direction of the yarn 20. The outer peripheral surface of the cam 88 is slidably in contact with the outer peripheral surface of the lock pin 87. The locking shaft 89 is disposed between the upstream plate 72a and the downstream plate 72b. The locking shaft 89 extends in the traveling direction of the yarn 20, and is fixed to the upstream plate 72a with a screw or the like.

  The locking arm 90 is provided with a locking shaft 89 on the base end side thereof, and is configured to be swingable about the locking shaft 89. A cam 88 is attached to the distal end side of the locking arm 90 so as to be rotatable around the axis of the cam 88. The torsion coil spring 91 is attached to the lock shaft 89. The torsion coil spring 91 urges the locking arm 90 so that the locking arm 90 does not swing with a force equal to or less than a predetermined force.

  In such a lock mechanism 86, as shown in FIG. 4, during normal winding, the cam 88 is engaged with the mounting shaft 77 side of the lock pin 87, whereby the swing arm 84 is closed in the closing direction. A predetermined force (predetermined force in the rotation direction around the rotation shaft 83) is applied. As a result, the wax molded body W supported on the swing arm 84 is strongly pressed to the front side, and the backlash of the wax molded body W is suppressed. On the other hand, as shown in FIG. 8, at the time of replacement work, the cam 88 is engaged with the side opposite to the mounting shaft 77 side of the lock pin 87, whereby the swing arm 84 has a predetermined force in the opening direction ( A predetermined force in the rotation direction around the rotation shaft 83 is applied.

  As shown in FIGS. 3 to 6, the positioning portion 92 contacts the wax molded body W supported by the wax support portion 76 via a predetermined traversing region P, and the wax molded body W with respect to the yarn 20. Perform positioning. The positioning portion 92 is disposed between the upstream plate 72a and the downstream plate 72b and faces the front side of the wax molded body W during normal winding. The positioning part 92 has a plurality of wax pins 93. The wax pin 93 is abutted against one end face of the wax molded body W supported by the wax support portion 76 during normal winding. The positioning portion 92 is fixed to the upstream plate 72a and the downstream plate 72b with screws or the like. That is, the positioning portion 92 is fixedly provided with respect to the housing 72.

  The upstream side regulation guide 94 and the downstream side regulation guide 96 are members that regulate the yarn path of the yarn 20. The upstream side regulation guide 94 and the downstream side regulation guide 96 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.

  The upstream side regulation guide 94 is provided at a position close to the upstream side in the traveling direction of the yarn 20 with respect to the wax molded body W during normal winding. The upstream side regulation guide 94 is provided at the starting point of a predetermined traverse region P. When viewed from the upstream side, the front end face of the upstream regulation guide 94 is located in the hole 74 a of the traverse guide part 74. The upstream regulation guide 94 is fixed to the inner surface of the upstream plate 72a (the surface on the downstream plate 72b side) with a screw or the like.

  The downstream side regulation guide 96 is provided at a position close to the downstream side in the traveling direction of the yarn 20 with respect to the wax molded body W during normal winding. The downstream side regulation guide 96 is provided on the back side with respect to the predetermined traverse region P. When viewed from the downstream side, the front end face of the downstream regulation guide 96 is located in the slit portion 74 b of the traverse guide portion 74. The downstream regulation guide 96 is fixed to the inner surface of the downstream plate 72b with a screw or the like.

  When the swinging arm 84 swings from the replacement operation to the normal winding (when the wax support portion 76 is closed), the buffer member 98 contacts the upright plate portion 84a of the swinging arm 84 and the downstream side plate 72b. Absorbs (buffers) the impact generated by As the buffer member 98, for example, a resin component can be used. The buffer member 98 is provided on the downstream plate 72b so as to be sandwiched between the downstream plate 72b and the upright plate portion 84a during normal winding. According to the buffer member 98, it is possible to suppress sound and damage caused by the contact between the upright plate portion 84a and the downstream plate 72b.

  In the wax applying device 70, as shown in FIG. 6, the reference angle for the yarn 20 to be derived is a bending angle θ1 that is bent from the reference surface S for the yarn 20 to be introduced toward the starting point of the predetermined traversing region P. The bending angle θ2 is larger than the bending angle θ2 from the surface S toward the package 30 side. The reference surface S is a surface along a contact portion between the wax molded body W and the predetermined traversing region P. The reference surface S is along the front end surfaces of the upstream side regulation guide 94 and the downstream side regulation guide 96. The bending angles θ1 and θ2 are angles between the reference surface S and the yarn 20, and are inclination angles from the reference surface S. The configuration for realizing the bending angles θ1 and θ2 is not particularly limited. For example, the bending angle θ1> the bending angle θ2 may be realized by changing the mounting angle of the wax applying device 70 with respect to the winder unit 2.

  Next, an example of an operation related to replacement of the wax molded body W in the wax applying device 70 will be described.

  When the wax molded body W is replaced in the normal winding state shown in FIGS. 3 and 4, for example, the operator pushes the front end of the pressing lever 78 toward the back side, and puts the upright plate portion 84 a toward the back side. Pushing in and applying a force to swing the swing arm 84 in the opening direction O.

  In the lock mechanism 86, a cam 88 is engaged with the lock pin 87, and a predetermined restricting force is applied to the swing arm 84 in the direction opposite to the opening direction O. Therefore, when the applied force is equal to or less than the predetermined force, the swing arm 84 does not swing. On the other hand, when a force greater than the predetermined force is applied, the lock pin 87 slides over the cam 88 and the swing arm 84 swings in the opening direction O. As a result, the wax support portion 76 swings and moves so that the front end portion of the wax molded body W is exposed outside the housing 72, and reaches the state at the time of the replacement operation shown in FIGS.

  When the swing arm 84 swings in the opening direction O, the swing restriction pin 78 c of the pressing lever 78 passes through the front side of the engagement piece 80. 7 and 8, the swing restricting pin 78c is urged rearward by the elastic force of the torsion coil spring, and the back side of the swing restricting pin 78c and the engaging piece The front side of 80 is engaged, and the swing restricting pin 78c cannot move to the back side any more. Therefore, in the state at the time of the replacement work, the swinging of the pressing lever 78 is restricted, and the pressing of the wax molded body W by the pressing lever 78 is stopped. As a result, it is possible to prevent the wax molded body W from being unintentionally pressed by the pressing lever 78 and coming out.

  Further, in the state of the replacement work, the cam 88 is engaged with the lock pin 87, and a predetermined restricting force is applied to the swing arm 84 in the direction opposite to the closing direction C. Therefore, even if the worker releases his / her hand, the swing arm 84 is prevented from returning (closed in the closing direction C), and the worker can easily perform the replacement work.

  In such a state at the time of replacement work, the operator, for example, a force for swinging the swing arm 84 in the closing direction C in order to return to the normal winding state after replacement with a new wax molded body W. Is granted. The swing arm 84 does not swing when the applied force is less than or equal to the predetermined force due to the restriction force of the lock mechanism 86 described above. On the other hand, when a force greater than the predetermined force is applied, the lock pin 87 slides over the cam 88, and the swing arm 84 swings in the closing direction C, as shown in FIGS. The normal winding state is reached.

  In the series of replacement operations described above, the casing 72 remains attached to the winder unit 2, and the traveling yarn 20 is moved in a predetermined traversing area by the traverse guide portion 74 fixedly provided on the casing 72. It continues to be guided to be traversed by forming P. Further, the wax support portion 76 is swung by the moving mechanism 82 without the wax support portion 76 and the wax molded body W passing (crossing) the predetermined traverse region P.

  As shown in FIGS. 4 and 9, in the state of normal winding, for example, when the wax molded body W is consumed and the pressing lever 78 swings in the direction of pressing the wax molded body W, The swing restricting pin 78c moves so as to pass the back side of the engaging piece 80. Therefore, in this case, the swing restricting pin 78c biased rearward does not engage with the engagement piece 80. As a result, the pressing lever 78 can press the wax molded body W toward the front side without being restricted in swinging.

  As described above, in the present embodiment related to the wax applying device 70 and the winder unit 2 and the automatic winder 1 including the wax applying device 70, the wax support 76 is used to form the wax molded body so as to be positioned at least in a part of the predetermined traversing region P. W is supported. The wax support portion 76 is attached to the housing 72 via a moving mechanism 82 configured to be movable in a direction away from a predetermined traversing region P in order to attach and detach the wax molded body W. Therefore, the wax support 76 can be moved by the moving mechanism 82 and the wax molded body W can be replaced. At this time, since the traverse guide portion 74 is fixedly provided on the housing 72, the yarn 20 wound by the package forming portion 8 is traversed regardless of the movement of the wax support portion 76 by the moving mechanism 82. Can be guided. Although the traverse guide portion 74 is fixedly provided on the housing 72, the traverse guide portion 74 may be configured to be slightly adjustable.

  Therefore, in the present embodiment in which the wax molded body W is positioned in at least a part of the traversing region P, the influence of the exchange of the wax molded body W on the yarn path (preventing the state where the yarn 20 is connected) is suppressed. It becomes possible to do. As a result, the wax molded body W can be easily replaced while the yarn 20 from the package 30 is connected. The wax molded body W can be replaced without loosening the traversed yarn 20. During the replacement operation of the wax molded body W, the traversed yarn 20 can be made difficult to catch. In addition, in the present embodiment, since the wax molded body W is positioned in at least a part of the traversing region P, the winder unit 2 can be reduced in height and thus reduced in size. The positioning accuracy between the wax molded body W and the traverse region P can be improved.

  In the wax applying device 70, the moving mechanism 82 moves the wax support 76 without passing the wax support 76 and the wax molded body W supported by the wax support 76 through the predetermined traversing region P. Thus, the wax molded body W can be attached and detached and replaced without passing the wax support 76 and the wax molded body W through the predetermined traversing region P.

  The wax applying device 70 includes a screw N and a screw hole 73 for attaching the casing 72 to the winder unit 2. Since the screw N and the screw hole 73 are fixedly provided in the casing 72, the casing 72 can be attached to the winder unit 2 regardless of the movement of the wax support portion 76 by the moving mechanism 82. Therefore, it is possible to suppress the influence of the replacement of the wax molded body W from being attached to the housing 72.

  The wax applying device 70 includes a positioning portion 92 that positions the wax molded body W with respect to the yarn 20. Since the positioning portion 92 is fixedly provided on the casing 72, the positioning accuracy of the wax molded body W by the positioning portion 92 can be ensured regardless of the movement of the wax support portion 76 by the moving mechanism 82. Therefore, it is possible to suppress the influence of the replacement of the wax molded body W on the positioning of the wax molded body W.

  In the wax applying device 70, the moving mechanism 82 rotates and moves the wax support portion 76 with respect to the housing 72 so as to rotate around the rotation shaft 83. According to this configuration, the wax molded body W can be easily replaced. The operator can easily replace the wax molded body W even in a narrow work space. A mechanism with little backlash can be realized with a small number of parts. The operator can easily replace the wax molded body W with one hand. It is possible to prevent the cable of the motor 79 from being largely dragged when the wax molded body W is replaced.

  The wax applying device 70 includes a lock mechanism 86 that restricts the moving mechanism 82 so that the wax support portion 76 does not move with a force equal to or less than a predetermined force set in advance. Thereby, for example, even when the worker moves his / her wax support portion 76 by the moving mechanism 82, the state of the wax support portion 76 (the state at the time of replacement work) can be maintained even when the worker releases his / her hand. The replacement of the wax molded body W with one hand can be easily realized, and the replacement work can be facilitated.

  In the wax applying device 70, the wax molded body W is located on the opposite side of the predetermined traversing region P. According to this configuration, it is possible to avoid the yarn path from being hidden by the wax molded body W when viewed from the front side. As a result, the wear surface of the wax molded body W can be visually recognized from the front side, and the ease of access to the wax molded body W can be improved.

  The wax applying device 70 includes an upstream side regulation guide 94, and the upstream side regulation guide 94 is upstream in the traveling direction of the yarn 20 with respect to the wax molded body W and on the back side with respect to the predetermined traversing region P. Is provided. The bending angle θ1 of the yarn 20 introduced into the wax applying device 70 is configured to be larger than the bending angle θ2 of the yarn 20 led out from the wax applying device 70. Thereby, the thread | yarn 20 introduce | transduced into the wax provision apparatus 70 can be effectively applied to the upstream regulation guide 94, and the tension | tensile_strength of the said thread | yarn 20 can be stabilized. As a result, the wax can be stably attached to the yarn 20. Furthermore, it becomes possible to suppress the damage (so-called ring breakage) of the wax caused by positioning the wax molded body W in the predetermined traversing region P.

  The winder unit 2 includes a yarn storage device 18 at a position upstream of the wax applying device 70 in the traveling direction of the yarn 20. According to this configuration, it is possible to suppress the influence of the exchange of the wax molded body W on the yarn path between the yarn storage device 18 and the package 30. Further, since the yarn joining device such as the yarn joining device 13 is not arranged on the yarn path between the yarn storage device 18 and the package 30, the wax molded body W can be easily replaced while the yarn from the package 30 is connected. The above effect is particularly effective.

[Second Embodiment]
Next, a wax applying apparatus according to the second embodiment will be described. In the description of the present embodiment, the description overlapping with the first embodiment will be omitted, and different points will be described.

  As shown in FIGS. 10 and 11, the wax application device 170 according to the second embodiment includes the movement mechanism 182 instead of the movement mechanism 82 (see FIG. 3), and the wax application of the first embodiment. Different from the device 70. 11 and 12, the positioning portion 92 is omitted for convenience of explanation.

  The moving mechanism 182 slides the wax support portion 76 relative to the housing 72 to open and close the wax support portion 76. That is, the moving mechanism 182 moves the wax support 76 between the state of the wax applying device 170 during normal winding (see FIG. 10) and the state of the wax applying device 170 during replacement (see FIG. 11). This is a slide open / close mechanism. The moving mechanism 182 allows the wax support 76 to move along an arc-shaped locus close to a straight line extending in the X direction so that the wax molded body W moves away from and approaches the predetermined traversing region P. . The arc shape here is an arc shape that is convex on the opposite side to the wax molded body W side. By moving the wax support portion 76 along an arcuate locus close to a straight line, the wax molded body W can be reliably separated from the predetermined traversing region P when the wax support portion 76 is moved. The formed body W is prevented from coming into contact with the yarn 20 in an unstable state.

  The moving mechanism 182 includes a slide plate 184 that slides in the X direction, and cam grooves 185 and 186 formed in the downstream plate 72b. An attachment shaft 77, a motor 79 and a pressing lever 78 are attached to the slide plate 184. The slide plate 184 is provided with an engagement pin 184a that protrudes downstream. The cam grooves 185 and 186 extend in an arc shape along the X direction which is the traverse direction. An engagement pin 184 a of the slide plate 184 is disposed in the cam groove 185. In the cam groove 186, a swing restricting pin 78c of the pressing lever 78 is disposed.

  According to such a moving mechanism 182, the cam pins 184 a and the swing restricting pin 78 c are guided by the cam grooves 185 and 186 along the X direction, respectively, and the engage pin 184 a and the swing restricting pin 78 c are guided by the cam grooves. 185 and 186, respectively. Thereby, the slide plate 184 slides along the X direction.

  Here, one end of the cam groove 186 communicates with a front / rear groove 187 extending to the back side. In the normal winding shown in FIG. 10, when the pressing portion 78b of the pressing lever 78 is located on the most back side, the swing restriction pin 78c is located on the most front side of the cam groove 186 (front / rear groove 187). In this state, the swing restricting pin 78c can move in the X direction along the cam groove 186, and as a result, the slide plate 184 can also slide along the X direction. On the other hand, during the normal winding, when the pressing portion 78b of the pressing lever 78 moves to the front side, the swing restriction pin 78c moves to the back side of the front and rear groove 187 accordingly. In this state, the swing restricting pin 78c cannot move in the X direction, and as a result, the slide plate 184 cannot slide along the X direction, and the slide movement of the moving mechanism 182 is locked.

  In the exchange operation shown in FIG. 11, the swing restricting pin 78 c is located at the other end of the cam groove 186. In this state, the swing restricting pin 78c cannot move to the back side, so the swinging of the pressing lever 78 is restricted, and the pressing of the wax molded body W by the pressing lever 78 is stopped. As a result, it is possible to prevent the wax molded body W from being unintentionally pressed by the pressing lever 78 and coming out.

  As described above, according to the present embodiment, in the wax applying device 170 that positions the wax molded body W in at least a part of the predetermined traversing region P, the influence of the exchange of the wax molded body W is prevented from reaching the yarn path. It becomes possible. Further, the moving mechanism 182 of the wax applying device 170 slides the wax support portion 76 with respect to the housing 72. According to this configuration, the wax molded body W can be easily replaced.

[Third Embodiment]
Next, a wax applying apparatus according to a third embodiment will be described. In the description of the present embodiment, the description overlapping with the first embodiment will be omitted, and different points will be described.

  As shown in FIG. 12, the wax applying device 270 according to the third embodiment is the first embodiment in that the predetermined traversing region P is a back-side device positioned on the back side with respect to the wax molded body W. It differs from the form of the wax applicator 70. The wax molded body W supported by the wax support portion 76 is located on the front side with respect to the predetermined traverse region P.

  The wax applying device 270 is different from the wax applying device 70 of the first embodiment in that a moving mechanism 282 is provided instead of the moving mechanism 82 (see FIG. 3). The moving mechanism 282 has a rotating plate 284 configured to be rotatable around a hinge 283. The rotating plate 284 is disposed on the front side in the wax applying device 270. The moving mechanism 282 rotates the rotating plate 284 around the hinge 283, thereby rotating the wax support 76 attached to the rotating plate 284 with respect to the housing 72. The moving mechanism 282 implements a front-opening type wax applying device 270 that opens the wax support 76 to the front side.

  As described above, according to the present embodiment, in the wax applying device 170 that positions the wax molded body W in at least a part of the predetermined traversing region P, the influence of the exchange of the wax molded body W is prevented from reaching the yarn path. It becomes possible.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment.

  FIG. 13 is a side view showing a wax applying apparatus according to a modification. As shown in FIG. 13, the upstream side regulation guide 94 and the downstream side regulation guide 96 according to the modification are such that the downstream side (upper side in the drawing) of the yarn path is higher than the upstream side (lower side in the figure) of the yarn path. The yarn path is regulated so as to be away from W. In the illustrated example, the front end portion of the downstream side regulation guide 96 is positioned on the front side of the front side distal end portion of the upstream side regulation guide 94. In other words, the downstream side regulation guide 96 protrudes to the front side (side away from the wax molded body W) from the upstream side regulation guide 94. When viewed from the side, a straight line connecting the tip of the downstream regulation guide 96 and the tip of the upstream regulation guide 94 is configured so as not to be orthogonal (90 ° crossing) with the axis of the wax molded body W.

  According to such a configuration, the upstream side of the wax molded body W can be effectively applied to the yarn 20, and the wax can be stably attached to the yarn 20. Further, it is possible to suppress the damage to the wax caused by positioning the wax molded body W in the predetermined traversing region P.

  FIG. 14A is a perspective view showing an upstream regulation guide according to a modification. FIG. 14B is a plan view showing an upstream regulation guide according to a modification. FIG. 14B shows a state viewed from the direction along the yarn path of the yarn 20. As shown in FIG. 14, when viewed from the direction along the yarn path of the yarn 20, the upstream side regulation guide 94 is on one side (the left side in the drawing) centering on the position of the yarn path in the X direction that is the traversing direction. The part may have a shape protruding in a direction away from the wax molded body W than the part on the other side (the right side in the figure).

  Specifically, in the upstream side regulation guide 94, the portion on the other side from the yarn path (traverse center) has a front surface 94x extending in a planar shape along the X direction. In the upstream side regulation guide 94, a portion on one side in the X direction from the yarn path protrudes to the front side with respect to the front surface 94x, and has a front surface 94y. The front surface 94y of the upstream side regulation guide 94 inclines in a curved shape so as to incline toward the front side as it goes from the yarn path position to one side in the X direction, and then traverses at a position on the front side of the front surface 94x. It extends in a planar shape along the direction.

  Here, the rotation direction CW of the wax molded body W is clockwise when viewed from the front. In this case, one side in the X direction protruding from the upstream side regulation guide 94 is the left side when viewed from the front. When the rotational direction CW of the wax molded body W is counterclockwise when viewed from the front, one side in the X direction protruding from the upstream side regulation guide 94 is the right side when viewed from the front.

  According to such a configuration, the wax molded body W can be effectively applied to the yarn 20, and the wax can be more stably adhered to the yarn 20. Furthermore, damage to the wax caused by positioning the wax molded body W in the predetermined traversing region P can be further suppressed.

  In the above-described embodiment, the yarn storage device 18 is omitted, and the yarn 20 of the yarn feeding unit 6 is configured to be directly wound by the package forming unit 8, and when the yarn 20 is divided, the yarn is fed from the package forming unit 8 to the yarn. 20 may be captured and introduced into the yarn joining device 13. In the above description, “fixedly provided” includes not only the case of being provided so as to be completely (integrated) fixed, but also the case of being provided so that the position can be adjusted via a position adjusting mechanism or the like.

  In the said embodiment, you may comprise so that supply of the new yarn supply bobbin 21 may be received not only from the structure which makes the yarn supply part 6 a tray conveyance type but from a magazine type bobbin supply apparatus. In this configuration, when the bobbin supplying device supplies a new yarn supplying bobbin 21 to the yarn supplying unit 6, the bobbin supplying device draws the yarn end from the yarn supplying bobbin 21 and delivers it to the upstream yarn blowing unit 11. It can also be. In this case, the auxiliary blowing part 28 can be omitted.
