  By the way, the bobbin holding device as described above may need to be removed from the winding unit in order to perform maintenance work, for example. As this maintenance work, for example, repainting of grease on the movable part of the bobbin holding device can be considered.

  However, in order to produce a high-quality package with a yarn winding machine, it is necessary to hold the yarn feeding bobbin in an accurate position in relation to the downstream yarn guide as described above. Therefore, once the bobbin holding device is removed from the winding unit, the position has to be strictly adjusted when it is attached again, which takes time. Therefore, further improvement has been desired from the viewpoint of improving the efficiency of maintenance work and the like.

  In this regard, Patent Document 1 does not disclose how the bobbin holding device is attached to the winding unit.

  The present invention has been made in view of the above circumstances, and the purpose thereof is to facilitate the positional relationship before removal when the bobbin holding device is reinstalled even when the bobbin holding device is removed for maintenance work or the like. It is to provide a winding unit that can be reproduced.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the 1st viewpoint of this invention, the winding unit of the following structures is provided. That is, the winding unit includes a bobbin holding device, a downstream unit, and a reference member. The bobbin holding device can hold a yarn feeding bobbin. The downstream unit guides the yarn unwound from the yarn supplying bobbin downstream in the yarn traveling direction and winds the yarn around a package. The reference member is attached to a base body that is a member that supports the downstream unit. The reference member is configured to be switchable between an adjustment state that is movable with respect to the base body and a fixed state that is immovable with respect to the base body. The bobbin holding device can be attached to and detached from the reference member. When the bobbin holding device is attached to the reference member, the bobbin holding device is attached to the reference member so that only one position is determined with respect to the reference member. Fixed.

  As a result, since the reference member is positioned and fixed to the base body and the bobbin holding device is fixed to the reference member, even if the bobbin holding device is removed, it is simply attached to the reference member again, and the positional relationship before removal. Can be easily reproduced. Therefore, the position can be adjusted only once, and it is not necessary to readjust each time the bobbin holding device is removed, so that the work can be made more efficient. In addition, since the positioning of the bobbin holding device, which is generally larger and heavier than the reference member, can be substantially realized by positioning the reference member, the positioning operation itself can be made more efficient.

  The winding unit is preferably configured as follows. That is, at least one of the base body and the reference member is provided with a hole, and the reference member is attached to the base body by inserting a bolt into the hole. A play is provided between the shaft portion of the bolt and the hole.

  Thereby, it is possible to switch between the adjustment state and the fixed state of the reference member with a simple configuration in which the bolt is loosened or tightened. Moreover, the structure which can adjust the position of a reference | standard member using the play formed around the axial part of a volt | bolt is easily realizable.

  The winding unit is preferably configured as follows. That is, the downstream unit includes an unwinding assist device that assists unwinding of the yarn from the yarn feeding bobbin. The reference member has a mark corresponding to the center position of the yarn feeding bobbin held by the bobbin holding device.

  Thus, when the reference member is attached to the base body, the positional relationship between the mark and the unwinding auxiliary device is adjusted, so that the bobbin holding device is held by the bobbin holding device when the bobbin holding device is attached to the reference member later. The center of the yarn feeding bobbin can be appropriately positioned in relation to the unwinding assisting device. In addition, since the operator performs alignment using the mark of the reference member instead of the bobbin holding device itself, the positional relationship is easily grasped visually. As a result, the efficiency of the alignment work can be realized.

  In the winding unit, the mark is preferably a recess or a through hole formed in the reference member.

  Thereby, since a mark can be obtained with a simple configuration, the cost of the winding unit can be reduced.

  The winding unit is preferably configured as follows. That is, the unwinding assisting device includes a cylindrical balloon regulating portion that adjusts the size of the balloon formed at the unwinding position where the yarn of the yarn feeding bobbin is unwound. In the adjustment state, the position of the reference member is adjusted so that the mark is positioned on an extension line of the axis of the balloon restricting portion.

  Thereby, when the bobbin holding device is attached to the reference member, the center of the yarn feeding bobbin held by the bobbin holding device can be positioned on the extension line of the axis of the balloon restricting portion. As a result, it is possible to prevent the balloon size from becoming uneven depending on the loop position when unwinding from the yarn feeding bobbin, and to apply a stable tension to the yarn to be unwound to form a high-quality package. it can.

  The winding unit can be configured as follows. That is, the downstream unit includes an unwinding assist device that assists unwinding of the yarn from the yarn feeding bobbin. The reference member can be attached with a reference jig serving as a mark at a position corresponding to the center position of the yarn feeding bobbin held by the bobbin holding device.

  As a result, when the reference member is attached to the base body, the bobbin holding device can be held when the bobbin holding device is attached to the reference member later by adjusting the positional relationship between the reference jig serving as a mark and the unwinding auxiliary device. The center of the yarn feeding bobbin held by the device can be appropriately positioned in relation to the unwinding assisting device. In addition, since the operator performs alignment using the reference jig instead of the bobbin holding device itself, the positional relationship is easily grasped visually. As a result, the efficiency of the alignment work can be realized.

  The winding unit is preferably configured as follows. That is, the unwinding assisting device includes a cylindrical balloon regulating portion that adjusts the size of the balloon formed at the unwinding position where the yarn of the yarn feeding bobbin is unwound. The reference jig is formed in a straight and long shape. In the adjustment state, the position of the reference member is adjusted so that the center of the reference jig and the axis of the balloon restricting portion coincide with each other after the reference jig is attached to the reference member.

  Thereby, when the bobbin holding device is attached to the reference member, the center of the yarn feeding bobbin held by the bobbin holding device can be positioned on the extension line of the axis of the balloon restricting portion. As a result, it is possible to prevent the balloon size from becoming uneven depending on the loop position when unwinding from the yarn feeding bobbin, and to apply a stable tension to the yarn to be unwound to form a high-quality package. it can.

  In the winding unit, the reference member is preferably formed in a plate shape.

  Thereby, the configuration for positioning the bobbin holding device can be simplified.

  In the winding unit, it is preferable that the reference member has a weight support portion that temporarily supports the weight of the bobbin holding device until the bobbin holding device is attached to the reference member.

  Accordingly, the bobbin holding device can be fixed to the reference member while the weight support portion supports the weight of the bobbin holding device, which is generally a heavy object. Therefore, compared to a configuration in which the operator performs the fixing operation while supporting the weight of the bobbin holding device by hand, the burden on the operator can be greatly reduced and the working efficiency can be increased.

  In the winding unit, it is preferable that one end of the bobbin holding device is attached to the reference member in a cantilever manner.

  Thereby, when the bobbin holding device is fixed to the reference member, the weight of the bobbin holding device is supported by the weight support portion, so that the bobbin holding device can be prevented from falling or tilting. Therefore, working efficiency can be improved.

  In the winding unit, the bobbin holding device is powered for at least one of alignment of the supplied yarn supplying bobbin, holding of the yarn supplying bobbin, and discharging of the yarn supplying bobbin. It is preferable that a drive source to be supplied is arranged.

  Accordingly, a configuration in which the bobbin holding device is not supplied with driving force from an external device (for example, a downstream unit) is realized. Accordingly, the bobbin holding device can be easily handled as a unit including the drive source, so that the efficiency of maintenance work and the like can be improved.

  According to a second aspect of the present invention, there is provided a yarn winding machine in which a plurality of the winding units described above are arranged.

  Thereby, in each winding unit, the position readjustment work becomes unnecessary when the bobbin holding device is detached / attached. Therefore, after the maintenance of the bobbin holding device or the like is completed, the winding by the winding unit can be resumed at an early stage, so that the operating efficiency of the yarn winding machine can be improved.

  The yarn winding machine is preferably configured as follows. That is, the base body is disposed so as to straddle a plurality of winding units and supports the downstream unit of each of the winding units. The reference members of a plurality of the winding units are attached to one base body.

  Thereby, simplification of the configuration of the yarn winding machine can be realized.

  According to the 3rd viewpoint of this invention, the attachment method of the bobbin holding | maintenance apparatus of the following structures is provided. That is, the winding unit to which the method for attaching the bobbin holding device is applied includes a bobbin holding device, a downstream unit, and a reference member. The bobbin holding device can hold a yarn feeding bobbin. The downstream unit guides the yarn unwound from the yarn supplying bobbin downstream in the yarn traveling direction and winds the yarn around a package. The reference member is attached to a base body that is a member that supports the downstream unit. And the attachment method of this bobbin holding device includes a first step, a second step, and a third step. In the first step, the reference member is brought into an adjustment state in which the reference member is movable with respect to the base body, and the position of the reference member is aligned with the downstream unit. In the second step, the reference member is switched to a fixed state in which the reference member cannot move with respect to the base body. In the third step, the bobbin holding device is fixed to the reference member.

  As a result, since the reference member is positioned and fixed to the base body and the bobbin holding device is fixed to the reference member, even if the bobbin holding device is removed, it is simply attached to the reference member again, and the positional relationship before removal. Can be easily reproduced. Therefore, the position adjustment (the first step and the second step) may be performed only once, and it is not necessary to readjust each time the bobbin holding device is removed, so that the work can be greatly improved in efficiency. In addition, since the positioning of the bobbin holding device, which is generally larger and heavier than the reference member, can be substantially realized by positioning the reference member, the positioning operation itself can be made more efficient.

Inside the unit frame 5, a unit controller 50 (see FIG. 3) that controls each part of the bobbin holding device 10 and the downstream unit 6 is arranged.

  The unit frame 5 includes a unit input unit 18 that can input settings of the bobbin holding device 10 and the downstream unit 6, and a unit display unit 19 that can display the status of the winding operation. The unit input unit 18 can be configured as a key or a button, for example.

  Since the machine control device 7 is configured to be communicable with the unit controller 50, the machine control device 7 can centrally manage the operations of the plurality of winder units 4. Further, the machine base control device 7 includes a machine base input unit 8 for making various settings (inputting the type of yarn feeding bobbin used for the winding operation of each winder unit 4) for each winder unit 4. And a machine base display section 9 capable of displaying the winding work status of each winder unit 4 and the like.

  Next, the winder unit 4 will be described in detail with reference to FIGS. FIG. 2 is a schematic side view of the winder unit 4. FIG. 3 is a block diagram showing a main configuration of the winder unit 4. The winder unit 4 is a device for winding the yarn 20 of the yarn supplying bobbin 21 around the winding bobbin 22 to form a package 29. Hereinafter, each part of the winder unit 4 will be described.

  As shown in FIGS. 1 and 2, the downstream unit 6 includes a bobbin supply device 60 that is disposed on the front side of the winder unit 4 and for supplying an yarn feeding bobbin 21 by an operator. The bobbin supply device 60 is installed below the magazine can 62, a magazine holder 61 that extends from the lower part of the winder unit 4 upward in the front direction, a magazine can 62 that is attached to the tip of the magazine holder 61, and the magazine can 62. The yarn feeding bobbin guide portion 64 and the opening / closing portion 68 are provided.

  The magazine can 62 is formed with a plurality of storage holes arranged in a circle, and the yarn feeding bobbin 21 can be set in an inclined posture in each storage hole. Further, the magazine can 62 is configured to be intermittently rotationally driven by a motor (not shown). The predetermined yarn feeding bobbin 21 can be dropped obliquely downward by intermittent driving of the magazine can 62 and opening / closing operation of a control valve (not shown) provided in the magazine can 62.

  The yarn feeding bobbin guide portion 64 is configured to slide the yarn feeding bobbin 21 dropped from the magazine can 62 obliquely and guide it to the bobbin holding portion 110 of the bobbin holding device 10.

  The bobbin holding device 10 includes a housing 115. As shown in FIG. 5, the housing 115 supports a bobbin holding portion 110 and a jump plate 40 for discharging the yarn feeding bobbin 21 (core tube 21a) after the unwinding of the yarn 20. Yes. The bobbin holding device 10 includes a drive unit 200 that operates the bobbin holding unit 110 and the jump plate 40. Details of the bobbin holding device 10 will be described later.

The pair of opening / closing members 68a and 68b can be switched between a closed state (the state shown in FIG. 2) and an open state. When the opening / closing part 68 is closed, the inner surface of the opening / closing part 68 constitutes a part of the yarn feeding bobbin guide part 64. That is, the inner surface of the opening / closing part 68 contacts the yarn feeding bobbin 21 falling from the magazine can 62 and guides the yarn feeding bobbin 21 to the bobbin holding device 10 obliquely below. On the other hand, in a state where the opening / closing portion 68 is open, the yarn feeding bobbin 21 that has been wound up and is not wound with the yarn 20 can be discharged to the front side. Since the conveyor 3 (see FIG. 1) is disposed on the front side of the opening / closing unit 68, the automatic winder 1 uses the conveyor 3 to transfer the yarn feeding bobbin 21 discharged from the opening / closing unit 68. Can be conveyed to a yarn feeding bobbin collection box (not shown) arranged at the end in the conveying direction.

  Further, the bobbin holding unit 110 is configured to be swingable in the front side and the back side when the stepping motor (motor) 100 shown in FIGS. 2 and 3 is driven. The stepping motor 100 is controlled by a stepping motor control unit (control unit) 102 shown in FIG. An origin sensor 101 is attached to an appropriate position of the bobbin holding device 10, and the rotation control of the stepping motor 100 is performed based on the rotation state of the stepping motor 100 detected by the origin sensor 101. The location and members for attaching the origin sensor 101 will be described later.

  Further, the bobbin holding part 110 can receive the yarn feeding bobbin 21 guided by the yarn feeding bobbin guiding part 64 by swinging from the back side to the front side. And the bobbin holding part 110 can make the received yarn feeding bobbin 21 substantially upright by swinging to the back side. The details of the mechanism for swinging the bobbin holding unit 110 by driving the stepping motor 100 and the control performed by the stepping motor control unit 102 will be described later.

  The yarn feeding bobbin 21 set in the bobbin holding unit 110 of the bobbin holding device 10 as described above is wound up by the winding unit 16 included in the downstream unit 6. As shown in FIG. 2, the winding unit 16 includes a cradle 23 configured to be capable of mounting the winding bobbin 22, a traverse drum 24 for traversing the yarn 20 and driving the winding bobbin 22. It is equipped with.

  The downstream unit 6 includes various devices supported by the unit frame 5 in the yarn traveling path between the bobbin holding device 10 and the traverse drum 24. Specifically, as the main devices arranged in the yarn traveling path, the yarn curl generation preventing device 11, the unwinding assisting device 12, and the bobbin holding device 10 side in order from the traverse drum 24 side, A tension applying device 13, a yarn joining device 14, and a clearer (yarn quality measuring device) 15 are arranged.

  As shown in FIG. 4, the unraveling assisting device 12 includes a fixed member 71, a movable member (balloon restricting portion) 72, an elevating member 73, and a chase portion detecting sensor 74. FIG. 4 is an enlarged perspective view showing the configuration of the unwinding assisting device 12.

  The fixing member 71 is fixed to the unit frame 5 via an appropriate member. A throttle part (not shown) for controlling the balloon is formed below the fixing member 71. The movable member 72 is formed in a cylindrical shape and is disposed so as to cover the outside of the fixed member 71. In the following description, the central axis of the movable member 72 configured in a cylindrical shape and a line obtained by extending the central axis are referred to as a virtual line L1.

  The elevating member 73 is formed integrally with the movable member 72. Since the elevating member 73 is configured to be movable in the vertical direction, the movable member 72 can be moved in the vertical direction. The elevating member 73 includes a chase portion detection sensor 74 for detecting the chase portion 21b (see FIG. 4) of the yarn feeding bobbin 21. The chase portion 21b is a yarn layer end portion of the yarn feeding bobbin 21 as the winding operation proceeds. Further, the chase portion detection sensor 74 is configured as a transmissive photosensor having a light projecting portion 74a and a light receiving portion 74b. As shown in FIG. 3, the detection signal detected by the chase detection sensor 74 is input to the unit controller 50.

  With this configuration, the movable member 72 can be positioned at a predetermined distance from the chase portion 21 b by operating the elevating member 73 based on the detection signal of the chase portion detection sensor 74. Then, as the yarn feeding bobbin 21 is unwound and the position of the chase portion 21b is lowered, the elevating member 73 is lowered so that the distance between the chase portion 21b and the movable member 72 can be always constant. Thereby, when the yarn feeding bobbin 21 is unwound, a balloon generated at a position where the yarn 20 is dissociated from the chase portion 21b can be appropriately regulated, and the tension of the yarn 20 unwound from the yarn feeding bobbin 21 can be regulated. The winding work can be performed while keeping the constant.

  Here, in order for the unwinding assisting device 12 to appropriately perform the unwinding assisting operation as described above, the unwinding side end of the yarn feeding bobbin 21 is well positioned at the position on the virtual line L1 (the unwinding reference position). Need to match. If the unwinding side end of the yarn feeding bobbin 21 is displaced from the unwinding reference position, the size of the balloon changes depending on the looping position of the yarn 20 when the yarn 20 is unwound from the yarn feeding bobbin 21; This is because uneven tension occurs. In this respect, in the present embodiment, the above requirements are satisfied by the control for adjusting the position of the unwinding side end of the yarn supplying bobbin 21 and the precise positioning of the bobbin holding device 10 itself, Good unwinding of the yarn 20 is realized. Details of these will be described later.

  On the back side of the unwinding assisting device 12, a yarn crimping prevention device 11 for preventing the yarn 20 from crimping is disposed. Here, the yarn curling is one of the problems that occur in the yarn, and is a state in which the yarn is curled and entangled in a spiral shape. The yarn crimping prevention device 11 includes a brush arm 11a and a brush portion 11b formed at the tip of the brush arm 11a. The brush arm 11 a is configured to be rotatable, and the brush portion 11 b can be brought into contact with the upper end portion of the yarn feeding bobbin 21 by being rotated. Thereby, an appropriate tension can be applied to the yarn 20 at the time of the yarn splicing operation or the like, and the occurrence of yarn crimping can be prevented.

  The tension applying device 13 applies a predetermined tension to the traveling yarn 20. The tension applying device 13 of this embodiment is configured as a gate type in which movable comb teeth are arranged with respect to fixed comb teeth. The movable comb teeth are configured to be rotatable by a rotary solenoid so that the comb teeth are in a meshed state or a released state.

  A lower thread detection sensor 31 is disposed between the unwinding assisting device 12 and the tension applying device 13. The lower thread detection sensor 31 is configured to be able to detect whether or not the thread 20 is traveling at the position where it is disposed.

  The clearer 15 is configured to detect a yarn defect (yarn defect) such as a slab by monitoring the thickness of the yarn 20. Further, a cutter 39 for cutting the yarn 20 immediately when the clearer 15 detects a yarn defect is disposed upstream (downward) of the yarn path from the clearer 15.

  The yarn joining device 14 detects when the clearer 15 detects a yarn defect and cuts the yarn 20 with the cutter 39, when the yarn 20 being unwound from the yarn feeding bobbin 21 is broken, or when the yarn feeding bobbin 21 At the time of replacement or the like, the lower thread on the yarn feeding bobbin 21 and the upper thread on the package 29 are spliced. As such a yarn splicing device 14, a device using a fluid such as compressed air or a mechanical device can be used.

  On the lower side and upper side of the yarn joining device 14, a lower yarn guide pipe 25 that catches and guides the lower yarn on the yarn feeding bobbin 21 side, and an upper yarn guide pipe 26 that catches and guides the upper yarn on the package 29 side. And are provided. A suction port 32 is formed at the tip of the lower thread guide pipe 25, and a suction mouth 34 is provided at the tip of the upper thread guide pipe 26. Appropriate negative pressure sources are connected to the lower thread guide pipe 25 and the upper thread guide pipe 26, respectively, and a suction force can be generated in the suction port 32 and the suction mouth 34.

  With this configuration, when the yarn feeding bobbin is replaced, the suction port 32 of the lower thread guide pipe 25 rotates downward to suck and capture the lower thread, and then rotates upward about the shaft 33. Thus, the lower thread is guided to the yarn joining device 14. At substantially the same time, the winder unit 4 rotates the upper thread guide pipe 26 upward from the position shown in FIG. 2 about the shaft 35 and reversely rotates the package 29 to be unwound from the package 29. The thread is captured by the suction mouse 34. Subsequently, the winder unit 4 guides the upper thread to the yarn joining device 14 by rotating the upper thread guide pipe 26 downward about the shaft 35. In the yarn joining device 14, the lower yarn and the upper yarn are joined.

  Further, a notification lamp 56 is arranged on the unit frame 5 as shown in FIGS. The notification lamp 56 is connected to the unit controller 50 as shown in FIG. 3, and can notify the operator of an abnormality that has occurred in each part of the downstream unit 6. The notification lamp 56 is configured to notify the operator of the occurrence of an abnormality using light, but may be configured to notify the operator with a buzzer or the like instead of this configuration.

  With the above configuration, each winder unit 4 of the automatic winder 1 can wind the yarn 20 unwound from the yarn feeding bobbin 21 onto the winding bobbin 22 to form a package 29 having a predetermined length.

  Next, the bobbin holding device 10 will be described in detail with reference to FIGS. FIG. 5 is a perspective view showing the configuration of the bobbin holding device 10.

Further, the bobbin holding part 110 includes a main core member (regulating member) 80 and an auxiliary core member (fixing member) 90. As shown in FIG. 7, the main core member 80 and the auxiliary core member 90 are closed when the yarn feeding bobbin 21 is supplied, and enter the inside of the core tube 21a. Then, the auxiliary core member 90 swings away from the main core member 80 from this state, so that the main core member 80 and the auxiliary core member 90 are opened, and the yarn feeding bobbin 21 can be held. Yes (see FIG. 8). Further, in the state where the holding of the yarn feeding bobbin 21 by the bobbin holding portion 110 is released, the spring plate 40 is swung to push out the bottom portion of the core tube 21a and remove it from the main core member 80 and the auxiliary core member 90. The yarn feeding bobbin 21 can be discharged (see FIG. 9).

  Next, the power transmission unit 120 will be described. The power transmission unit 120 is configured to oscillate the main core member 80, and includes a main core member drive cam 81, a bearing 82, a swing arm 83, a positioning arm 84 a, a contact arm 84 b, and a transmission shaft 85. And a pressing spring 86. The power transmission unit 120 includes a transmission belt 103, a pulley 104, and a cam shaft 105 as a configuration for transmitting the power of the stepping motor 100 to the main core member drive cam 81 and the like.

  The pulley 104 is fixed to the cam shaft 105, and the pulley 104 is connected to the output shaft of the stepping motor 100 via the transmission belt 103. Although the transmission belt 103 is simply illustrated in FIG. 5, the transmission belt 103 is configured as a toothed timing belt and can transmit the rotation of the output shaft of the stepping motor 100 to the cam shaft 105 without slipping.

  An origin sensor 101 (not shown in FIG. 5) is attached to the pulley 104. The origin sensor 101 sends a detection signal when the pulley 104 or the camshaft 105 is in a predetermined rotational phase. It is configured. The rotation state when the origin sensor 101 transmits a detection signal is the origin of the stepping motor 100, and the rotation control of the stepping motor 100 is performed based on this origin.

  The main core member drive cam 81 is fixed to the cam shaft 105 and rotates integrally with the cam shaft 105. A swing arm 83 is disposed on the back side of the main core member drive cam 81, and a rotatable bearing 82 is attached to a middle portion of the swing arm 83. The bearing 82 is configured to be able to rotate appropriately while contacting the outer peripheral surface of the main core member drive cam 81.

  The tip of the swing arm 83 is connected to the lower end of a positioning arm 84a supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. A rotatable rotating member 87 is supported on the upper end portion of the positioning arm 84a.

  A contact arm 84b is disposed on the front side of the positioning arm 84a. The tip of the contact arm 84b is configured to be able to contact the rotating member 87 attached to the positioning arm 84a. One end of the transmission shaft 85 is fixed to the base portion of the contact arm 84 b, and the other end of the transmission shaft 85 is fixed to the main core member 80. That is, the transmission shaft 85 and the main core member 80 are configured to be interlocked. Accordingly, the main core member 80 rotates integrally with the contact arm 84b. Further, a torsion coil spring-like pressing spring 86 is attached to the contact arm 84b, and urges the contact arm 84b in the direction of the arrow in FIG.

  With the above configuration, since the elastic force of the pressing spring 86 acts on the contact arm 84b, the protruding portion contacts the rotating member 87 and pushes the positioning arm 84a. Furthermore, since the lower end portion of the positioning arm 84a pulls the swing arm 83 through the link, the bearing 82 of the swing arm 83 is pressed against the main core member drive cam 81. Thus, the pressing spring 86 makes the main core member drive cam 81 and the bearing 82 contact, and generates a spring force for bringing the contact arm 84b into contact with the positioning arm 84a.

  In this state, when the main core member driving cam 81 rotates and the peripheral edge portion (bulging portion described later) of the main core member driving cam 81 presses the bearing 82, the swing arm 83 rotates in a direction away from the cam shaft 105. The tip of the swing arm 83 pulls the lower end of the positioning arm 84a through the link. As a result, the rotation member 87 at the upper end of the positioning arm 84a pushes the contact arm 84b, so that the main core member 80 can be swung to the front side together with the contact arm 84b (see FIG. 8).

  In addition, the power transmission unit 120 is configured to transmit the power of the stepping motor 100 to the auxiliary core member 90, as an auxiliary core member drive cam 91, a bearing 92, a swing arm 93, a transmission arm 94, and a transmission shaft. 95 and a holding spring 96.

  The auxiliary core member drive cam 91 is fixed to the cam shaft 105 in the same manner as the main core member drive cam 81. A swing arm 93 is disposed on the back side of the auxiliary core member drive cam 91, and a rotatable bearing 92 is attached to a middle portion of the swing arm 93. The bearing 92 is configured to be able to rotate as appropriate while in contact with the outer peripheral surface of the auxiliary core member drive cam 91.

  The tip of the swing arm 93 is connected to the lower end of a transmission arm 94 supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. One end of a transmission shaft 95 is attached to the base of the transmission arm 94, and the other end of the transmission shaft 95 is fixed to the auxiliary core member 90. That is, the transmission shaft 95 and the auxiliary core member 90 are configured to be interlocked. Therefore, the auxiliary core member 90 rotates integrally with the transmission arm 94. Further, a torsion coil spring-like holding spring 96 is attached to the transmission arm 94, and the transmission arm 94 is urged in the direction of the dotted line arrow in FIG.

  With the above-described configuration, the holding spring 96 applies the spring force in the direction in which the auxiliary core member 90 swings to the back side (the direction away from the main core member 80) via the transmission arm 94 and the transmission shaft 95. 90. At the same time, the distal end portion of the transmission arm 94 to which the elastic force of the holding spring 96 acts pulls the swing arm 93 through the link, so that the bearing 92 of the swing arm 93 is pressed against the auxiliary core member drive cam 91. In this manner, the holding spring 96 generates a spring force for bringing the auxiliary core member drive cam 91 and the bearing 92 into contact with each other.

  In this state, when the auxiliary core member drive cam 91 rotates and the peripheral edge portion (a bulge portion described later) of the auxiliary core member drive cam 91 presses the bearing 92, the swing arm 93 swings away from the cam shaft 105. The tip of the swing arm 93 pulls the lower end of the transmission arm 94 through the link. As a result, the auxiliary core member 90 can be swung to the front side (direction approaching the main core member 80).

  In addition, when the auxiliary core member 90 is swung to the front side beyond a predetermined angle, the auxiliary core member 90 comes into contact with an unillustrated portion of the main core member 80, and thereafter, the auxiliary core member 90 is the main core member 90. The core member 80 is configured to swing as a single unit (in this case, the distal end portion of the contact arm 84b and the rotating member 87 are appropriately separated). That is, in a state where the auxiliary core member 90 is swung to the front side beyond a predetermined angle, the main core member 80 is driven by the auxiliary core member driving cam 91 instead of the main core member driving cam 81. .

  Next, a configuration for driving the jump plate 40 will be described. The power transmission unit 120 is configured to transmit the power of the stepping motor 100 to the jumping plate 40, and includes a jumping plate driving cam 41, a bearing 42, a swing arm 43, a transmission arm 44, a transmission shaft 45, and a return shaft. And a spring 46.

  The jump plate drive cam 41 is fixed to the cam shaft 105 in the same manner as the auxiliary core member drive cam 91 and the main core member drive cam 81. A swing arm 43 is disposed on the back side of the jump plate drive cam 41, and a rotatable bearing 42 is attached to a middle portion of the swing arm 43. The bearing 42 is configured to be able to rotate as appropriate while in contact with the outer peripheral surface of the spring plate drive cam 41.

  The tip of the swing arm 43 is connected to the lower end of the transmission arm 44 supported so as to be swingable at an appropriate position of the power transmission unit 120 via a bar-shaped link. One end of the transmission shaft 45 is fixed to the base portion of the transmission arm 44, and the other end of the transmission shaft 45 is fixed to the spring plate 40. That is, the transmission shaft 45 and the jump plate 40 are configured to be interlocked. Therefore, the spring plate 40 rotates integrally with the transmission arm 44. Further, a torsion coil spring-like return spring 46 is attached to the transmission arm 44 to urge the transmission arm 44 in the direction of the arrow in FIG.

  With the above configuration, the distal end portion of the transmission arm 44 to which the elastic force of the return spring 46 acts pulls the swing arm 43 through the link, so that the bearing 42 of the swing arm 43 presses against the jump plate drive cam 41. It is done. In this way, the return spring 46 generates a spring force for bringing the spring plate drive cam 41 and the bearing 42 into contact with each other.

  In this state, when the jump plate drive cam 41 rotates and the peripheral portion (bulge portion described later) of the jump plate drive cam 41 presses the bearing 42, the swing arm 43 moves in a direction away from the cam shaft 105, and the swing plate drive cam 41 moves. The tip of the moving arm 43 pulls the lower end of the transmission arm 44 through the link. As a result, the jump plate 40 can be flipped up to the front side (see FIG. 9).

  Next, a configuration in which the winder unit 4 receives the yarn feeding bobbin 21, holds the yarn feeding bobbin 21 at a predetermined position where the yarn 20 is unwound, and discharges it will be described. As described above, in the present embodiment, the jump plate driving cam 41, the main core member driving cam 81, and the auxiliary core member driving cam 91 are configured as the cam coupling mechanism 130 fixed to the common cam shaft 105. The two cams 41, 81, 91 are integrally driven. Further, as shown in FIG. 6, the three cams 41, 81, 91 are respectively formed with bulges, and the postures of the jump plate 40, the main core member 80, and the auxiliary core member 90 are changed by the bulges. Can do. The bulge part of the auxiliary core member drive cam 91 and the bulge part of the jump plate drive cam 41 are formed gently, while the bulge part of the main core member drive cam 81 is formed slightly sharper. In addition, the bulging portion of the auxiliary core member driving cam 91 and the bulging portion of the jump plate driving cam 41 are formed in substantially the same phase, while the bulging portion of the main core member driving cam 81 is formed in a phase that is substantially 180 ° different from them. Has been.

  In the above configuration, when the yarn feeding bobbin 21 is received, the stepping motor 100 is appropriately driven to rotate the three cams 41, 81, 91, and the bearing 92 included in the swing arm 93 is used to drive the auxiliary core member. The cam 91 is brought into contact with a portion slightly passing the peak portion of the bulging portion, and the rotation of the cams 41, 81, 91 is stopped in this state. Thereby, as shown in FIG. 7, the auxiliary core member 90 is slightly tilted from the upright state to the front side.

  In this state, since the auxiliary core member 90 is swung beyond a predetermined angle, the main core member 80 is also swung to the front side in a form pushed by the auxiliary core member 90 as described above. As in the auxiliary core member 90, the posture is slightly tilted from the upright state to the front side. When the yarn feeding bobbin 21 is supplied from the magazine holding unit 61 in this state, the bobbin holding unit 110 (the main core member 80 and the auxiliary core member 90) enters the core tube 21a. In this specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is received (the posture in FIG. 7) is referred to as a receiving posture.

  When the yarn 20 is unwound from the received yarn feeding bobbin 21, the stepping motor 100 is driven again, and the cam shaft 105 is rotated in the direction indicated by the arrow in FIG. Thereby, the bearings 42 and 92 which the rocking | fluctuation arms 43 and 93 have pass the bulge part completely in the spring board drive cam 41 and the auxiliary core member drive cam 91, and come to contact a non-bulge part. Further, the bearing 82 included in the swing arm 83 comes into contact with the bulging portion of the main core member drive cam 81.

  Accordingly, as shown in FIG. 8, the jumping plate 40 swings from the state of FIG. 7 to the back side and becomes horizontal, and the auxiliary core member 90 swings so that it slightly falls to the back side. Further, as described above, the main core member 80 that has been pushed to the front side by the auxiliary core member 90 also swings to the back side in the same manner as the auxiliary core member 90 swings to the back side. Eventually, the contact arm 84 b comes into contact with the rotating member 87 of the positioning arm 84 a to stop the main core member 80 from swinging. Thereafter, only the auxiliary core member 90 swings back by the spring force of the holding spring 96. It will be. That is, since the auxiliary core member 90 is displaced so as to be relatively away from the main core member 80, the core tube 21a of the yarn supplying bobbin 21 can be held from the inside by the bobbin holding portion 110.

  At this time, the posture in which the swing of the main core member 80 is stopped is determined by the position of the rotating member 87 of the positioning arm 84a. Further, since the positioning arm 84a is connected to the swing arm 83 via a link, the posture of the main core member 80 is such that the bearing 82 of the swing arm 83 is in the bulge portion of the main core member drive cam 81. It can be changed depending on which part is in contact (whether it is in contact with the rising part of the bulging part or the peak part). In other words, the posture of the main core member 80 can be adjusted by changing the rotational phase of the main core member drive cam 81. Even when the posture of the main core member 80 is changed in this way, the auxiliary core member 90 can maintain the holding state of the yarn feeding bobbin 21 without any problem by the elastic force of the holding spring 96.

  In this specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is unwound is referred to as the unwinding posture. Further, the origin sensor 101 detects the rotational phase of the pulley 104 when the main core member 80 is in an almost upright posture as shown in FIG. 8, and this state is used in the rotation control of the stepping motor 100. It is set to be the origin. Since the unwinding posture of the main core member 80 changes depending on the type of the yarn feeding bobbin 21, the origin detected by the origin sensor 101 does not always match the unwinding posture.

  Next, when discharging the yarn feeding bobbin 21, the stepping motor 100 is appropriately driven to rotate the three cams 41, 81, 91. As a result, the bearings 42 and 92 of the swing arms 43 and 93 come into contact with the bulging portions of the jump plate driving cam 41 and the auxiliary core member driving cam 91. Therefore, as shown in FIG. 9, the spring plate 40 swings greatly to the front side. Further, in conjunction with this, the auxiliary core member 90 swings to the front side to release the holding of the yarn feeding bobbin 21, and the auxiliary core member 90 greatly increases the front side while pushing the main core member 80. Swing. Thereby, the spring board 40 pushes up the lower end of the core tube 21a of the yarn supplying bobbin 21, and the yarn supplying bobbin 21 can be discharged. In the present specification, the posture of the main core member 80 when the yarn feeding bobbin 21 is discharged is referred to as a discharging posture.

  As described above, in the present embodiment, the yarn feeding bobbin 21 is received and held in the unwinding posture (and the unwinding posture) only by driving the stepping motor 100 as a single drive source. Adjustment) and the yarn feeding bobbin 21 can be discharged.

  Next, with reference to FIGS. 10 to 12, a series of flows when the automatic winder 1 performs winding while replacing the yarn feeding bobbin 21 will be described. FIG. 10 is a flowchart showing a process performed by the winder unit 4 when a yarn break or the like occurs. FIG. 11 is a side view showing the first half of the state in which the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted. FIG. 12 is a side view showing the latter half of the state where the position of the unwinding side end of the yarn feeding bobbin 21 is adjusted.

  During the winding operation by the winder unit 4, the clearer 15 detects a yarn defect and cuts the yarn 20 with the cutter 39, the yarn 20 being unwound from the yarn feeding bobbin 21 is broken, In some cases, the yarn 20 of the yarn bobbin 21 is unwound and the yarn 20 is lost. The winder unit 4 monitors the yarn breakage (S101), and when the yarn breakage occurs, the winding operation is stopped (S102).

  Then, when the winding operation is stopped, the lower thread suction and capture by the suction port 32 of the lower thread guide pipe 25 positioned below and the upper thread suction and capture by the upper thread guide pipe 26 are performed. Yarn splicing at the splicing device 14 is started (S102). Thereafter, the unit controller 50 determines whether or not there is a lower thread after piecing based on the detection result of the lower thread detection sensor 31 (S103).

  When the yarn 20 is cut or unwound by the cutter 39, the yarn 20 remains on the yarn feeding bobbin 21, and the splicing is completed if no mechanical error occurs. To do. Accordingly, the lower thread detection sensor 31 detects the lower thread. In this case, the unit controller 50 controls the components of the bobbin holding device 10 and the downstream unit 6 to resume the winding of the yarn 20.

  On the other hand, when all of the yarns 20 of the yarn feeding bobbin 21 have been unwound and the yarns 20 are no longer present, the lower yarn detection sensor 31 does not detect the lower yarn because the yarn splicing cannot be performed. At this time, the unit control unit 50 determines that the unwinding of the yarn 20 of the yarn supplying bobbin 21 is completed, and operates the bobbin holding unit 110 and the jump plate 40 to perform the discharging process of the core tube 21a (S104). . Thereafter, the unit controller 50 causes the bobbin supply device 60 to newly supply the yarn supplying bobbin 21 (S105). At this time, the stepping motor control unit 102 drives the stepping motor 100 to move the main core member 80 to the receiving posture in advance.

  The newly supplied yarn feeding bobbin 21 is guided to the bobbin holding device 10 as shown in FIG. Then, the stepping motor control unit 102 swings the bobbin holding unit 110 toward the back side.

  Note that the winder unit 4 of the present embodiment has a layout of the bobbin holding unit 110 so that the yarn feeding bobbin 21 crosses the detection range of the chase detection sensor 74 when the bobbin holding unit 110 is swung back. Has been taken into account. Then, the unit controller 50 determines whether or not the yarn feeding bobbin 21 is newly supplied based on the detection result of the chase detection sensor 74 (S106). Specifically, when the yarn feeding bobbin 21 is detected by the chase part detection sensor 74 after the unit controller 50 instructs to newly supply the yarn feeding bobbin 21, the yarn feeding bobbin 21 is newly supplied. It is judged that it was done. On the other hand, if the yarn feeding bobbin 21 is not detected by the chase portion detection sensor 74 within a predetermined time, it is determined that the yarn feeding bobbin 21 is not newly supplied.

  When it is determined that the yarn feeding bobbin 21 is newly supplied, the unit controller 50 captures the yarn end of the newly supplied yarn supplying bobbin 21 and the yarn end on the package 29 side, and the yarn by the yarn joining device 14 The splicing is started (S110).

  When determining that the yarn feeding bobbin 21 is not newly supplied, the unit controller 50 sends an appropriate signal to the notification lamp 56 without starting the yarn splicing operation. The notification lamp 56 that has received this signal notifies the operator that the yarn feeding bobbin 21 is not newly supplied by using a preset display color or the like (S107).

  Then, the unit controller 50 of the present embodiment determines that the yarn feeding bobbin 21 is not newly supplied, sends an appropriate signal to the notification lamp 56, and continues until the trouble is resolved. The catching operation, the catching operation of the upper thread, and the yarn splicing are not performed. Further, the operator can know that the yarn feeding bobbin 21 is not supplied to the bobbin supply device 60 by the notification of the notification lamp 56. Then, the operator can stop the notification of the notification lamp 56 by supplying the yarn feeding bobbin 21 to the bobbin supplying device 60 (S108) and operating the error release button (S109). Thereafter, the bobbin supply device 60 newly supplies the yarn supplying bobbin 21 according to an instruction from the unit control unit 50 (S105).

  The unit controller 50 determines again whether or not the yarn feeding bobbin 21 has been supplied in the same manner as described above (S106). When it is determined that the yarn feeding bobbin 21 has been supplied, the unit control unit 50 captures the yarn end of the newly supplied yarn feeding bobbin 21 and the yarn end on the package 29 side, and starts piecing (S110). .

  Subsequently, the unit control unit 50 adjusts the position of the unwinding side end of the yarn feeding bobbin 21 in parallel with the yarn splicing (S111). Hereinafter, control for adjusting the position of the unwinding side end of the yarn supplying bobbin 21 will be described with reference to FIGS. 11 to 13. FIG. 13 is a flowchart showing a process for adjusting the position of the unwinding side end of the yarn supplying bobbin 21.

  In the winder unit 4 of this embodiment, the bobbin holding part 110 is actually swung so that the yarn feeding bobbin 21 crosses the chase part detection sensor 74 provided in the unwinding assisting device 12, and then the chase part detection sensor 74 is Based on the timing at which the yarn feeding bobbin 21 is detected, the position of the yarn feeding bobbin 21 is adjusted. Thereby, the winder unit 4 of this embodiment has a configuration in which the unwinding side end of the yarn feeding bobbin 21 can be accurately positioned at the unwinding reference position. Further, the winder unit 4 of the present embodiment is configured to cover the yarn feeding bobbin 21 by the movement of the movable member 72 of the unwinding assisting device 12, but as described above, the unwinding side of the yarn feeding bobbin 21 By accurately positioning the end, contact between the movable member 72 and the yarn feeding bobbin 21 can be reliably prevented.

  This will be specifically described below. That is, the stepping motor control unit 102 controls the stepping motor 100 to rotate the main core member 80 in the receiving posture to the back side so that the yarn feeding bobbin 21 is once erected. At this time, the unit controller 50 applies an appropriate tension to the yarn 20 by bringing the brush portion 11b of the yarn crimping prevention device 11 into contact with the upper end portion of the yarn feeding bobbin 21 as shown in FIG. Then, the occurrence of yarn crimping is prevented (S201). Thereafter, the stepping motor control unit 102 swings the bobbin holding unit 110 so as to slightly tilt the yarn feeding bobbin 21 to the front side again (S202). Then, when the yarn feeding bobbin 21 is detected by the chase part detection sensor 74, the unit controller 50 stops the swinging of the bobbin holding part 110 (S203, FIG. 12 (a)).

  The unit control unit 50 includes a memory serving as a storage unit. This memory supplies the yarn if the stepping motor 100 is driven by how many pulses from the position where the yarn feeding bobbin 21 starts to be detected by the chase detection sensor 74. Whether the bobbin 21 can be in an appropriate position (adjustment distance) is stored in association with the type of the yarn feeding bobbin 21 to be used. The operator inputs the type of yarn feeding bobbin 21 to be used to the unit input unit 18 before starting the winding operation. Thereby, the adjustment distance which should be used in the present winding operation | work is set to the unit control part 50. FIG. Then, the unit control unit 50 outputs a predetermined number of pulses to the stepping motor 100 based on the set adjustment distance, and swings the bobbin holding unit 110 to the back side (S204, FIG. 12B). ).

  Thereby, the unwinding side end of the yarn feeding bobbin 21 can be adjusted to the unwinding reference position. Therefore, the contact between the movable member 72 and the yarn feeding bobbin 21 can be prevented while appropriately exerting the function of the unwinding assisting device 12.

  If the type of the yarn feeding bobbin 21 to be used is changed, an appropriate adjustment distance can be set in the unit control unit 50 by performing an appropriate input to the unit input unit 18. Further, this input can be made to the machine base input unit 8 instead of being made to the unit input unit 18. In this case, the machine base control device 7 transmits the content input to the machine base input unit 8 to each winder unit 4. Thereby, an appropriate adjustment distance can be set collectively for the unit control unit 50 of each winder unit 4.

  Next, assembly of the bobbin holding device 10 to the automatic winder 1 will be described with reference to FIGS. 14 to 17. FIG. 14 is a perspective view showing how the reference plate 141 is attached to the first frame member 151 of the machine base frame. FIG. 15 is a side view showing how the reference plate 141 is aligned with the unwinding assisting device 12. FIG. 16 is a perspective view showing how the bobbin holding device 10 is fixed to the reference plate 141. FIG. 17 is a side view showing a case where the reference jig 143x is attached to the reference plate 141 for alignment.

  As described above, the winder unit 4 includes the bobbin holding device 10 and the downstream unit 6, which are supported by a common machine base frame (base body). Specifically, the automatic winder 1 includes a machine frame that is elongated in the direction in which the winder units 4 are arranged. The machine frame includes a first frame member 151 and a second frame member 152 as shown in FIG. And a third frame member 153. These frame members 151 to 153 are connected to each other by a connecting member (not shown).

  The first frame member 151 is formed in a square pipe shape and is arranged at the lower part of the machine base. The second frame member 152 is formed in a round pipe shape and is disposed at a height above the first frame member 151. The third frame member 153 has a rectangular cross section and is disposed slightly above the second frame member 152.

  With the above machine frame structure, the bobbin holding device 10 is fixed to the first frame member 151 as shown in FIG. On the other hand, the downstream unit 6 is fixed to the second frame member 152 and the third frame member 153. As described above, the bobbin holding device 10 and the downstream unit 6 are separated from each other and are separately attached to the machine frame, so that the mounting position of the bobbin holding device 10 is adjusted independently of the downstream unit 6. can do.

  The bobbin holding device 10 is not directly attached to the first frame member 151 but is attached so as to interpose a reference plate (reference member) 141 which is a plate-like member. FIG. 14 shows how the reference plate 141 is attached to the first frame member 151.

  The reference plate 141 is formed as a substantially L-shaped plate in plan view having a predetermined thickness. The reference plate 141 is formed with an adjustment hole (hole) 142, a position confirmation hole (mark, through hole) 143, a bobbin holding device fixing hole 144, and a hooking hole (weight support portion) 145. Yes.

  The adjustment holes 142 are circular holes formed in a penetrating manner, and two adjustment holes 142 are provided at an appropriate interval. A shaft portion of a fastening bolt (bolt) 161 that is a fixing tool for attaching the reference plate 141 to the first frame member 151 can be inserted into the adjustment hole 142. The reference plate 141 can be attached to the first frame member 151 by screwing the tightening bolt 161 into the nut 162 fixed to the first frame member 151 side.

  The diameter of the adjustment hole 142 is set to be somewhat larger than the diameter of the shaft portion of the tightening bolt 161. Due to the play thus formed, the reference plate 141 is displaced within a certain range when the tightening bolt 161 is loosened. Can do.

  The position confirmation hole 143 is formed as a through hole formed in the reference plate 141. The position confirmation hole 143 is formed at a position corresponding to the axis of the bobbin holding portion 110 of the bobbin holding device 10 when the bobbin holding device 10 is attached to the reference plate 141.

  The bobbin holding device fixing hole 144 is a screw hole formed in a penetrating shape, and two bobbin holding device fixing holes 144 are provided at an appropriate interval. The bobbin holding device 10 can be fixed to the reference plate 141 in the bobbin holding device fixing hole 144 by using a fixing screw 171 shown in FIG.

  As shown in FIG. 14, the hooking hole 145 is configured as a circular hole formed in a penetrating manner. The hooking hole 145 is configured so that the insertion protrusion 118 included in the bobbin holding device 10 shown in FIG. 16 can be inserted.

  As shown in FIG. 14, the first frame member 151 is formed with a through hole for allowing the shaft portion of the tightening bolt 161 to pass therethrough, as well as a bobbin holding device fixing hole 144 and a hooking hole. A through hole is also formed in a portion corresponding to 145. The through holes corresponding to the bobbin holding device fixing holes 144 and the hooking holes 145 do not block the bobbin holding device fixing holes 144 and the hooking holes 145 even when the reference plate 141 is displaced as will be described later. It is formed slightly larger.

  In this configuration, when the bobbin holding device 10 is assembled to the automatic winder 1, the operator attaches the reference plate 141 to the first frame member 151 as shown in FIG. However, at this time, the operator does not completely tighten the tightening bolt 161 but keeps it loosened to some extent. Then, the reference plate 141 can move on the first frame member 151 within a stroke range corresponding to the amount of play formed between the adjustment hole 142 and the shaft portion of the tightening bolt 161. (Adjusted state).

  In this state, the operator confirms the position confirmation hole 143 from above, and the position confirmation hole 143 is positioned on the extension line (the virtual line L1) of the movable member 72 of the unwinding assisting device 12. In this manner, the position of the reference plate 141 is moved and adjusted (see FIG. 15). In FIG. 15, the adjustment by moving the reference plate 141 to the back side or the front side is indicated by an arrow. However, since the play of the adjustment hole 142 is provided over the entire circumference, The direction is arbitrary. Accordingly, the reference plate 141 can be adjusted by moving in the direction perpendicular to the above (that is, the direction in which the winder units 4 are arranged, the direction along the longitudinal direction of the first frame member 151). After the above alignment is completed, the operator strongly tightens the fastening bolt 161 to fix the reference plate 141 so as not to move (fixed state).

  Next, the operator fixes the bobbin holding device 10 to the reference plate 141 positioned as described above as shown in FIG. The housing 115 provided in the bobbin holding device 10 is formed in an elongated shape in a direction perpendicular to the first frame member 151, and a mounting plate 116 having a predetermined thickness is disposed on the lower surface of the housing 115 at a position near the end of the portion. It is fixed to.

  The attachment plate 116 is formed with two through-hole attachment holes 117. The mounting holes 117 are disposed on both sides of the housing 115 and are disposed at positions corresponding to the bobbin holding device fixing holes 144 formed in the reference plate 141. In addition, a cylindrical insertion protrusion 118 that protrudes downward is provided on the lower surface of the mounting plate 116.

  With the above configuration, first, the operator inserts the insertion protrusion 118 on the lower surface of the bobbin holding device 10 into the hooking hole 145 formed in the reference plate 141 so that the bobbin holding device 10 is placed on the reference plate 141. Put it on. In this way, the bobbin holding device 10 is cantilevered at one end, but the dimensions are set so that only a slight gap is formed between the insertion protrusion 118 and the hooking hole 145. The insertion protrusion 118 can be hooked into the hooking hole 145 so that the bobbin holding device 10 can be supported so as not to fall. Here, the bobbin holding device 10 includes the housing 115, the stepping motor 100, the cam coupling mechanism 130, and the like, and has a considerably large weight as a whole. However, according to the configuration of the present embodiment, Since the attaching work can be performed in a state where the weight of the holding device 10 is supported, the burden on the operator can be greatly reduced.

  Next, the operator inserts the fixing screws 171 into the respective mounting holes 117 and screws them into the bobbin holding device fixing holes 144. Here, a strict tolerance is set between the fixing screw 171, the mounting hole 117, and the bobbin holding device fixing hole 144 so as not to cause backlash. Accordingly, by tightening the two fixing screws 171, the bobbin holding device 10 can be fixed to the reference plate 141 so that the position of the bobbin holding device 10 with respect to the reference plate 141 is determined to be only one.

  As described above, the installation of the bobbin holding device 10 is completed and the winding operation can be performed. As described above, the position confirmation hole 143 provided in the reference plate 141 is the axis of the bobbin holding unit 110 of the bobbin holding device 10. It is arranged at a position corresponding to. Accordingly, the position confirmation hole 143 is aligned with the axis of the movable member 72 of the unwinding assisting device 12 to fix the reference plate 141, and then the bobbin holding device 10 is fixed to the reference plate 141, whereby the bobbin holding portion 110 is fixed. Is coincident with the axis of the movable member 72 of the unwinding assisting device 12. Accordingly, in conjunction with the position control of the unwinding side end of the yarn feeding bobbin 21 described above, the unwinding assisting work by the unwinding assisting device 12 can be appropriately performed.

  By the way, it may be necessary to remove the bobbin holding device 10 from the automatic winder 1 and perform maintenance work for some reason, such as the need for repainting the grease described above. In this case, the operator only needs to remove the bobbin holding device 10 while removing the fixing screw 171 (without removing the tightening bolt 161) and leaving the reference plate 141 on the first frame member 151 side. After the maintenance of the bobbin holding device 10 is completed, the state in which the bobbin holding device 10 is properly positioned can be reproduced simply by attaching the bobbin holding device 10 to the reference plate 141. Therefore, the winding operation can be resumed immediately.

  Next, a modified example of the operation of adjusting the position of the reference plate 141 will be described with reference to FIG. In addition, in the modification of FIG. 17, the same code | symbol may be attached | subjected to drawing to the same or similar member as above-mentioned embodiment, and description may be abbreviate | omitted.

  In the example of FIG. 17, the operator prepares a reference jig 143x that can be attached to and detached from the position confirmation hole 143 of the reference plate 141, and inserts the reference jig 143x into the position confirmation hole 143 and stands upright. Perform alignment work. As a result, the alignment reference (axis) is visually clarified, so that more precise positioning can be realized. After the alignment is completed, the reference jig 143x is removed from the reference plate 141 so as not to interfere with the attachment of the bobbin holding device 10.

  As described above, the winder unit 4 of this embodiment includes the bobbin holding device 10, the downstream unit 6, and the reference plate 141. The bobbin holding device 10 can hold the yarn supplying bobbin 21. The downstream unit 6 guides the yarn 20 unwound from the yarn supplying bobbin 21 downstream in the yarn traveling direction and winds the yarn 20 around the package 29. The reference plate 141 is attached to a machine base frame (specifically, a first frame member 151 constituting the machine base frame) that is a member that supports the downstream unit 6. The reference plate 141 is in an adjustment state in which it can move with respect to the first frame member 151 and in a state in which it cannot move with respect to the first frame member 151 by loosening or tightening the tightening bolt 161. The fixed state can be switched. The bobbin holding device 10 can be attached to and detached from the reference plate 141. When the bobbin holding device 10 is attached to the reference plate 141, the bobbin holding device 10 is fixed to the reference plate 141 so that only one position is determined with respect to the reference plate 141.

  As a result, the reference plate 141 is positioned and fixed to the first frame member 151 and the bobbin holding device 10 is fixed to the reference plate 141. Therefore, even when the bobbin holding device 10 is removed, the reference plate 141 is attached again. Thus, the positional relationship before removal can be easily reproduced. Therefore, it is only necessary to adjust the position once, and it is not necessary to readjust each time the bobbin holding device 10 is removed, so that the work can be made more efficient. In addition, since the positioning of the bobbin holding device 10 that is generally larger and heavier than the reference plate 141 can be substantially realized by positioning the reference plate 141, the positioning operation itself can be made more efficient.

  Further, in the winder unit 4 of the present embodiment, the reference plate 141 is provided with an adjustment hole 142, and the reference plate 141 is attached to the first frame member 151 by inserting the tightening bolt 161 into the adjustment hole 142. Yes. A play is provided between the shaft portion of the tightening bolt 161 and the adjustment hole 142.

  Thereby, the adjustment state and the fixed state of the reference plate 141 can be switched with a simple configuration in which the tightening bolt 161 is loosened or tightened. Further, it is possible to easily realize a configuration in which the position of the reference plate 141 can be adjusted by using play formed around the shaft portion of the tightening bolt 161.

  Further, in the winder unit 4 of the present embodiment, the downstream unit 6 includes an unwinding assisting device 12 that assists unwinding of the yarn 20 from the yarn supplying bobbin 21. The reference plate 141 has a position confirmation hole 143 as a mark corresponding to the center position of the yarn feeding bobbin 21 held by the bobbin holding device 10.

  Accordingly, when the reference plate 141 is attached to the first frame member 151, by adjusting the positional relationship between the mark and the unwinding auxiliary device 12, when the bobbin holding device 10 is attached to the reference plate 141 later, The center of the yarn feeding bobbin 21 held by the bobbin holding device 10 can be appropriately positioned in relation to the unwinding auxiliary device 12. In addition, since the operator performs alignment using the mark on the reference plate 141 instead of the bobbin holding device 10 itself, the positional relationship is easily grasped visually. As a result, the efficiency of the alignment work can be realized.

  Further, in the winder unit 4 of the present embodiment, the position confirmation hole 143 as a through hole formed in the reference plate 141 is used as the mark.

  Thereby, since a mark can be obtained with a simple configuration, the cost of the winder unit 4 can be reduced.

  In the winder unit 4 of this embodiment, the unwinding assisting device 12 is a cylindrical movable member 72 that adjusts the size of the balloon formed at the unwinding position where the yarn 20 of the yarn feeding bobbin 21 is unwound. Is provided. In the state where the tightening bolt 161 is loosened (the above-described adjustment state), the position of the reference plate 141 is adjusted so that the position confirmation hole 143 is positioned on the extension line of the axis of the movable member 72.

  Thereby, when the bobbin holding device 10 is attached to the reference plate 141, the center of the yarn feeding bobbin 21 held by the bobbin holding device 10 can be positioned on the extension line of the axis of the movable member 72. As a result, it is possible to prevent the balloons from becoming non-uniform in size due to the orbiting position when unwinding from the yarn feeding bobbin 21, and to apply a stable tension to the yarn 20 unwound from the yarn feeding bobbin 21 to achieve high quality. The package 29 can be formed.

  In the configuration of the modified example of FIG. 17, the reference plate 141 can be attached with a reference jig 143 x serving as a mark at a position corresponding to the center position of the yarn feeding bobbin 21 held by the bobbin holding device 10.

  Accordingly, when the reference plate 141 is attached to the first frame member 151, the positional relationship between the reference jig 143x serving as a mark and the unwinding assisting device 12 is adjusted, whereby the bobbin holding device 10 is later attached to the reference plate 141. When attached to the bobbin, the center of the yarn feeding bobbin 21 held by the bobbin holding device 10 can be appropriately positioned in relation to the unwinding assisting device. In addition, since the operator performs alignment using the reference jig 143x instead of the bobbin holding device 10 itself, the positional relationship is easily grasped visually. As a result, the efficiency of the alignment work can be realized.

  Further, in the configuration of the modification example described above, the position of the reference plate 141 coincides with the center of the reference jig 143x and the axis of the movable member 72 in a state where the tightening bolt 161 is loosened (the adjustment state described above). To be adjusted.

  Thereby, when the bobbin holding device 10 is attached to the reference plate 141, the center of the yarn feeding bobbin 21 held by the bobbin holding device 10 can be positioned on the extension line of the axis of the movable member 72. As a result, it is possible to prevent the balloons from becoming non-uniform in size depending on the turning position when unwinding from the yarn feeding bobbin 21, and to apply a stable tension to the yarn 20 to be unwound to form a high-quality package 29. can do.

  In the winder unit 4 of the present embodiment, the reference plate 141 is a member formed in a plate shape.

  Thereby, the configuration for positioning the bobbin holding device 10 can be simplified.

  In the winder unit 4 of the present embodiment, the reference plate 141 has a hook hole 145 that temporarily supports the weight of the bobbin holding device 10 until the bobbin holding device 10 is fixed to the reference plate 141. Have.

  Accordingly, the bobbin holding device 10 can be fixed to the reference plate 141 while supporting a large weight of the bobbin holding device 10 with the hooking hole 145 part. Therefore, compared to a configuration in which the operator performs the fixing operation while supporting the weight of the bobbin holding device 10 by hand, the burden on the operator can be greatly reduced and the working efficiency can be increased.

  In the winder unit 4 of this embodiment, the bobbin holding device 10 is attached to the reference plate 141 in a cantilevered manner at one end side.

  Thereby, when the bobbin holding device 10 is fixed to the reference plate 141, the weight of the bobbin holding device 10 is supported by the hooking hole 145, so that the bobbin holding device is prevented from falling or tilting. it can. Therefore, working efficiency can be improved.

  Further, in the winder unit 4 of the present embodiment, the bobbin holding device 10 is provided with a stepping motor 100. The stepping motor 100 supplies a driving force for aligning the supplied yarn supplying bobbin 21 (adjustment of the unwinding posture), holding the yarn supplying bobbin 21, and discharging the yarn supplying bobbin 21.

  As a result, a configuration in which the bobbin holding device 10 is not supplied with driving force from an external device (for example, the downstream unit 6) is realized. Therefore, the bobbin holding device 10 can be easily handled as a unit including the drive source so that the maintenance work and the like can be efficiently performed.

  Moreover, the automatic winder 1 of this embodiment has a configuration in which a plurality of winder units 4 having the above-described configuration are arranged side by side.

  Thereby, in each winder unit 4, the position readjustment work becomes unnecessary when the bobbin holding device 10 is removed / attached. Therefore, after the maintenance of the bobbin holding device 10 is completed, the winding by the winder unit 4 can be restarted at an early stage, so that the operating efficiency of the automatic winder 1 can be increased.

  Further, in the automatic winder 1 of the present embodiment, the machine base frame to which the reference plate 141 is attached is disposed so as to straddle the plurality of winder units 4. Then, the reference plates 141 of the plurality of winder units 4 are attached to one machine base frame (first frame member 151).

  Thereby, simplification of the structure of the automatic winder 1 is realizable.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  Instead of the reference plate 141 formed in a plate shape, for example, a block-shaped member can be attached to the first frame member 151 and used.

  The adjustment hole 142 having play may be formed not on the reference plate 141 but on the first frame member 151 side.

  The mark attached to the reference plate 141 is not limited to a through-hole as in the position confirmation hole 143. For example, the reference plate 141 may be a recess opening on the upper surface of the reference plate 141, a protrusion protruding from the upper surface, It is possible to make a scale or a cross mark engraved on the mark.

  Instead of forming the hooking hole 145 in the reference plate 141, the reference plate 141 can be provided with an insertion protrusion, and can be modified such that a recess or a through hole is provided on the housing 115 side of the bobbin holding device 10.

  The configuration of the bobbin holding device 10 is not limited to that shown in the above embodiment, and can be changed as appropriate. For example, the stepping motor 100 powers only a part of the supplied yarn supplying bobbin 21 (not adjusting the unwinding posture), holding the yarn supplying bobbin 21, and discharging the yarn supplying bobbin 21. The structure which supplies may be sufficient.
