     DESCRIPTION OF EMBODIMENTS 
     Problems to be Solved by Present Disclosure 
     When switching to a winding bobbin to start winding, winding can be started using the winding device disclosed in Patent Literature 1. 
     However, when winding is started at the beginning (when pulling out is started), an operator needs to hold the optical fiber up to the bobbin and wind the optical fiber around the bobbin. 
     Since a wire body is continuously supplied from the optical fiber base material side even during the operation, the operator needs to quickly wind an optical fiber around the bobbin. 
     When the bobbin is increased in size and the bobbin is supported from both sides, there is no work space for the operator, and thus it is difficult for the operator to perform a bobbin winding operation. 
     The present disclosure has been made in view of such circumstances, and an object of the present disclosure is to provide a wire body winding device and a wire body winding method that automatically and easily wind the wire body around a bobbin. 
     Effects of Present Disclosure 
     According to the present disclosure, it is possible to automatically and easily wind a wire body around a bobbin. 
     Embodiments of Present Disclosure 
     First, contents of embodiments of the present disclosure will be listed and described. 
     According to an aspect of the present disclosure, (1) there is provided a wire body winding device that winds a wire body around a bobbin. The wire body winding device includes a bobbin pivoting mechanism that pivotally supports and pivots the bobbin, a wire body holding mechanism that holds the wire body, and a wire body moving mechanism configured to move the wire body holding mechanism, in which at the time of pulling out, the wire body moving mechanism moves the wire body holding mechanism between a take-up position where the wire body holding mechanism is configured to hold the wire body and a wire body winding position where the wire body is configured to be wound around the bobbin. 
     Accordingly, an operator can wind the wire body around the bobbin only by holding the wire body in the wire body holding mechanism, and the operator does not directly wind the wire body around the bobbin, so that a winding operation around the bobbin can be automated and simplified. 
     (2) In the wire body winding device described above, a plurality of the bobbin pivoting mechanisms are provided, and each of the bobbin pivoting mechanisms includes a rotation shaft that is inserted into one end side of the bobbin to drive the bobbin, a motor that rotates the rotation shaft, and a support shaft that is inserted into the other end side of the bobbin to support the bobbin. 
     Accordingly, all bobbins are supported from both sides, and support strength of the bobbins is increased. Therefore, even when all of the bobbins have a large size, the bobbins can be supported. 
     In a case where the bobbins are supported from both sides (double-sided), when the operator directly winds the wire body around a bobbin, it may be difficult for the operator to put his hand to the bobbin. In the wire body winding device described above, when the wire body holding mechanism holds the wire body, the wire body holding mechanism is automatically moved up to a wire body winding position, so that the winding operation can be performed automatically and easily even when the bobbin has a double-sided structure. 
     (3) In the wire body winding device described above, the bobbin has a wire body catching portion that locks the wire body, and the wire body winding device further includes a bobbin selection mechanism configured to set the bobbin around which the wire body is to be wound, and a wire body cleaving mechanism configured to cleave the wire body locked to the bobbin. 
     Accordingly, since the wire body is wound around another bobbin without reducing a wire body speed, the wire body is continuously wound without loss. 
     (4) In the wire body winding device described above, the wire body holding mechanism is at least one of a suction nozzle configured to suction the wire body or a pinch roller configured to pinch the wire body. 
     Accordingly, the optical fiber is reliably held at the time of being pulled out. 
     (5) In the wire body winding device described above, a moving speed of the wire body holding mechanism is slower than a wire body pulling out speed of the wire body. Accordingly, a shortage of the optical fiber supplied from an optical fiber base material side is avoidable. Therefore, the optical fiber is not strongly pulled by the wire body holding mechanism during a movement of the wire body holding mechanism and the optical fiber is not broken, and the optical fiber can be efficiently wound around the bobbin. 
     (6) According to another aspect of the present disclosure, there is provided a wire body winding method using a wire body winding device. The wire body winding device includes a plurality of bobbin pivoting mechanisms that pivotally support and pivot a bobbin around which a wire body is to be wound, a wire body holding mechanism that holds the wire body, a wire body moving mechanism configured to move the wire body holding mechanism, a bobbin selection mechanism configured to set the bobbin around which the wire body is to be wound, and a wire body cleaving mechanism configured to cleave the wire body. The wire body winding method includes a holding step of the wire body holding mechanism holding the wire body at the time of being pulled out, a moving step of moving the wire body holding mechanism to a wire body winding position where the wire body is configured to be wound around the bobbin after the holding step, a setting step of the bobbin selection mechanism setting the bobbin around which the wire body is to be wound after the moving step, a locking step of a wire body catching portion of the bobbin locking the wire body after the setting step, and a cleaving step of the wire body cleaving mechanism cleaving the wire body locked to the bobbin after the locking step. 
     Accordingly, an operator can wind the wire body around the bobbin only by holding the wire body in the wire body holding mechanism, and the operator does not directly wind the wire body around the bobbin, so that a winding operation around the bobbin can be automated and simplified.

     Further, the present disclosure is not limited to these examples, is indicated by the claims, and is intended to include modifications within a scope and meaning equivalent to the claims. 
     [Wire Body Winding Device] 
     First, a specific structure of the winding device  100  will be described with reference to  FIGS. 1A to 1C . 
     The winding device  100  according to an embodiment of the present disclosure is a device used to wind an optical fiber that is a wire body around two bobbins B 1  and B 2  as shown in  FIGS. 1A to 1C . 
     In the bobbin used in the present embodiment, flanges are provided at two ends of a cylindrical body portion, and an engagement hole H to be engaged with a kere pin  121   b  which will be described later is formed in one flange. 
     As shown in  FIGS. 1A to 1C , the winding device  100  includes a frame  110  that faces both flange surfaces of the bobbins B 1  and B 2 , a bobbin pivoting mechanism  120  that pivotally supports and pivots the bobbins B 1  and B 2 , a wire body moving mechanism  130  that is attached to the frame  110  and moves the optical fiber into the winding device  100 , and a wire body holding mechanism  140  that holds the optical fiber. 
     The winding device  100  further includes a bobbin selection mechanism  150  that sets a bobbin around which the optical fiber is to be wound, a cutter (wire body cleaving mechanism)  160  that cuts off the optical fiber, and wire body aligning guides  170  that are movable in a front-rear direction and push the optical fiber. 
     [Frame] 
     The frame  110  includes a first frame  111  that accommodates a motor  123  and the like to be described later, and a second frame  112  that faces the first frame  111  at a given distance from the first frame  111 . 
     The bobbins B 1  and B 2  are disposed between the first frame  111  and the second frame  112 . 
     A first guide rail  111   b  and a second guide rail  111   c  that extend in a left-right direction are provided on a front surface  111   a  of the first frame  111 . 
     A cross-sectional shape of the first guide rail  111   b  and the second guide rail  111   c  is, for example, a circular shape as shown in  FIG. 1C . 
     The first guide rail  111   b  is provided above the second guide rail  111   c . Further, a length of the first guide rail  111   b  in the left-right direction is shorter than a length of the second guide rail  111   c  in the left-right direction. 
     [Bobbin Pivoting Mechanism] 
     The bobbin pivoting mechanism  120  includes a first bobbin pivoting mechanism  120 A that pivots the bobbin B 1  and a second bobbin pivoting mechanism  120 B that pivots the bobbin B 2 . 
     A pivoting direction of the bobbin B 1  by the first bobbin pivoting mechanism  120 A is clockwise in a front view, and a pivoting direction of the bobbin B 2  by the second bobbin pivoting mechanism  120 B is counterclockwise in a front view. 
     The first bobbin pivoting mechanism  120 A and the second bobbin pivoting mechanism  120 B have the same structure, and thus only the first bobbin pivoting mechanism  120 A will be described below. 
     The first bobbin pivoting mechanism  120 A includes, in the first frame  111 , a rotation shaft  121  of which one end is inserted into one end side of the bobbin B 1  to drive the bobbin B 1 , a bearing  122  that supports a load of the bobbin B 1  on the rotation shaft  121 , the motor  123  that rotates the rotation shaft  121 , and a transmission belt  124  that couples the rotation shaft  121  and the motor  123  to transmit the rotation of the motor  123  to the rotation shaft  121 . 
     Further, the first bobbin pivoting mechanism  120 A includes, in the second frame  112 , a support shaft  125  that is inserted into the other end side of the bobbin B 1  and supports the bobbin B 1 , a sleeve  126  that covers the support shaft  125 , and a bearing  127  that supports a load of the bobbin B 1  on the sleeve  126  (the support shaft  125 ). 
     The rotation shaft  121  is inserted into the bobbin B 1  at a front end side, and a pulley  121   a  is press-fitted to a rear end side of the rotation shaft  121 . 
     The transmission belt  124  is hung on the pulley  121   a.    
     A kere pin  121   b  that extends in the same direction as the rotation shaft  121  is provided at a side of the front end side of the rotation shaft  121 . 
     When the rotation shaft  121  is inserted into the bobbin B 1 , the kere pin  121   b  is inserted into the engagement hole H of the bobbin B 1 . 
     Accordingly, the bobbin B 1  does not idle relative to the rotation shaft  121 , and can be pivoted integrally with the rotation shaft  121 . 
     The support shaft  125  is slidable in the front-rear direction relative to the sleeve  126 . 
     Accordingly, the bobbins B 1  and B 2  can be attached to the winding device  100  or the bobbins B 1  and B 2  can be detached from the winding device  100  only by sliding the support shaft  125 . 
     [Wire Body Moving Mechanism] 
     The wire body moving mechanism  130  is a mechanism for moving the wire body holding mechanism  140  in upper, lower, left, and right directions. As shown in  FIG. 1C , the wire body moving mechanism  130  includes a horizontal slide portion  131  that is movable in the left-right direction on the first guide rail  111   b  of the first frame  111 , and a vertical slide portion  132  that is movable in a vertical direction. 
     The horizontal slide portion  131  includes a slide member  131   a  through which the first guide rail  111   b  is inserted and that is movable on the first guide rail  111   b , an arm  131   b  of which a rear end is connected to a front side of the slide member  131   a  and that extends forward, and a coupling member  131   c  to which a front end of the arm  131   b  is connected and that is coupled to the vertical slide portion  132 . 
     The vertical slide portion  132  includes a guide shaft  132   a  that extends in the vertical direction and is inserted through the coupling member  131   c , and a guide shaft holding member  132   b  that has a rectangular parallelepiped shape and is provided at a lower end of the guide shaft  132   a.    
     The wire body holding mechanism  140  is held on a rear surface of the guide shaft holding member  132   b.    
     Since the horizontal slide portion  131  and the vertical slide portion  132  are provided, the wire body moving mechanism  130  and the wire body holding mechanism  140  are movable between a take-up position P 1  where the optical fiber can be held at the time of starting to be pulled out and a wire body winding position P 2  where the optical fiber can be wound around the bobbins B 1  and B 2 , as shown in  FIG. 1B . 
     Here, the take-up position P 1  refers to a position at a left end side of the first frame  111 , and the wire body winding position P 2  refers to a position at substantially the center of the first frame  111  (that is, substantially the middle of two wire body aligning guides  170  in a front view). The wire body winding position P 2  is located below a cutter  160  when the wire body holding mechanism  140  is moved. 
     [Wire Body Holding Mechanism] 
     The wire body holding mechanism  140  is a mechanism that holds the optical fiber drawn from the optical fiber base material when the optical fiber is pulled out, and may be a pinch roller that holds the optical fiber by sandwiching the optical fiber with two rollers, may be a suction nozzle that holds the optical fiber by a negative pressure, or may be a combination of the pinch roller and the suction nozzle. 
     [Bobbin Selection Mechanism] 
     The bobbin selection mechanism  150  includes a slider  151  that is movable in the left-right direction on the second guide rail  111   c , a shaft  152  that extends forward from the slider  151 , and a guide roller  153  that has a V groove and is connected to a front end of the shaft  152 . 
     When the bobbin selection mechanism  150  is moved in the left-right direction, a bobbin on which the optical fiber is to be wound can be selected. 
     [Cutter] 
     The cutter  160  is attached to the first frame  111 , and includes an arm  161  coupled to the first frame  111 , and a cutter blade  162  attached to a tip end of the arm  161 . 
     [Wire Body Winding Method] 
     Next, a method of winding the optical fiber by the winding device  100  described above will be described with reference to  FIGS. 2A to 2H . 
     As shown in  FIG. 2A , a pull-out portion FL at a tip end of the optical fiber F that was pulled out from the optical fiber base material (not shown) is conveyed by a hand or the like, and is held by the wire body holding mechanism  140  at the take-up position P 1  in a state in which tension is adjusted by a dancer roller D. 
     When the pull-out portion FL of the optical fiber F is held by the wire body holding mechanism  140 , as shown in  FIG. 2B , the wire body moving mechanism  130  moves along the first guide rail  111   b  until the wire body moving mechanism  130  is positioned in the middle of the two wire body aligning guides  170  in a front view. 
     Thereafter, as shown in  FIG. 2C , the guide shaft  132   a  is lowered downward, so that the guide shaft holding member  132   b  is lowered vertically downward to the wire body winding position P 2 . 
     That is, the wire body holding mechanism  140  holds the pull-out portion FL of the optical fiber F and is moved from the take-up position P 1  to the wire body winding position P 2 . 
     Accordingly, the optical fiber F is wound around the guide roller  153  of the bobbin selection mechanism  150 . 
     A moving speed of the horizontal slide portion  131  and the vertical slide portion  132  at this time is slower than a pulling out speed from the optical fiber base material (that is, a wire body pulling out speed of the optical fiber). 
     However, since the optical fiber F remained in the wire body holding mechanism  140  are suctioned, the optical fiber F does not remain on the dancer roller D or the optical fiber F on a pass line is not loosened. 
     Next, the bobbin selection mechanism  150  is moved to a bobbin side around which the optical fiber F is to be wound. 
     In order to wind the optical fiber F around the bobbin B 1 , as shown in  FIG. 2D , the bobbin selection mechanism  150  is moved to the left side along the second guide rail  111   c  in the present embodiment. 
     A cross-sectional plan view of the winding device  100  at this time is  FIG. 2E . 
     Next, as shown in  FIG. 2F , the wire body aligning guides  170  are moved rearward (toward the first frame  111 ) to align the optical fiber F to a flange side of the bobbin B 1 . 
     At this time, the optical fiber F comes into contact with a flange of the bobbin B 1 . 
     In this state, the bobbin B 1  is rotated. 
     Accordingly, as shown in  FIG. 2G , the optical fiber F is caught by a claw N that is a wire body catching portion for locking the optical fiber F to the bobbin B 1 , and the optical fiber F is locked to the bobbin B 1 . 
     When the bobbin B 1  is further rotated, the optical fiber F is pressed against the cutter  160 , and the optical fiber F is cleft as shown in  FIG. 2H . 
     Thereafter, winding of the optical fiber F around the bobbin B 1  is started. 
     A procedure of winding the pull-out portion FL of the optical fiber F around the bobbin B 1  for the first time has been described above. 
     When the pull-out portion FL of the optical fiber F is to be wound around the bobbin B 2  for the first time, the pull-out portion FL of the optical fiber F may be held by the wire body holding mechanism  140 , and the bobbin selection mechanism  150  may be moved up to the wire body winding position P 2  and then aligned to the bobbin B 2  side. 
     [Switching of Winding Bobbins] 
     Next, switching of bobbins for winding the optical fiber will be described with reference to  FIG. 2H  and  FIG. 2I . 
     When the winding of the optical fiber F around the bobbin B 1  is started from the state shown in  FIG. 2H  and the winding of the optical fiber F around the bobbin B 1  is completed, the bobbin selection mechanism  150  is moved to a right side along the second guide rail  111   c  as shown in  FIG. 2I  in order to wind the optical fiber F around the bobbin B 2 . Next, the wire body aligning guides  170  are moved rearward (toward the first frame  111 ) to align the optical fiber F to a flange side of the bobbin B 2 . 
     Then, the bobbin B 2  is rotated, so that the optical fiber F is caught by a claw N, and the optical fiber F is locked to the bobbin B 2 . 
     When the bobbin B 2  is further rotated, the optical fiber F is pressed against the cutter  160 , and the optical fiber F is cleft. 
     Thereafter, winding of the optical fiber F around the bobbin B 2  is started. 
     In the winding device  100  according to the first embodiment of the present disclosure configured as described above, when pulling out is started, the wire body holding mechanism  140  is movable between the take-up position P 1  where the optical fiber F that is a wire body can be held and the wire body winding position P 2  where the optical fiber F can be wound around the bobbins B 1  and B 2 . 
     When the wire body holding mechanism  140  holds the optical fiber F and moves from the take-up position P 1  to the wire body winding position P 2 , an operator can wind the optical fiber F around the bobbins B 1  and B 2  only by holding the optical fiber F in the wire body holding mechanism  140 , and a winding operation around the bobbins B 1  and B 2  can be automated and simplified. 
     A plurality of bobbin pivoting mechanisms  120  are provided, and each of the bobbin pivoting mechanisms  120  includes the rotation shaft  121  that is inserted into one end side of each of the bobbins B 1  and B 2  and drives each of the bobbins B 1  and B 2 , the motor  123  that rotates the rotation shaft  121 , and a support shaft  125  that is inserted into the other end side of each of the bobbins B 1  and B 2  and supports each of the bobbins B 1  and B 2 , so that the bobbins B 1  and B 2  can be supported from both sides, and support strength of the bobbins B 1  and B 2  is increased. Therefore, even when the bobbins B 1  and B 2  have a large size, both of the bobbins B 1  and B 2  can be supported. 
     Further, the wire body holding mechanism  140  holds the optical fiber F, and then the wire body holding mechanism  140  is automatically moved up to the wire body winding position P 2 , so that the winding operation can be performed automatically and easily even when the bobbins B 1  and B 2  have a double-sided structure. 
     The bobbins B 1  and B 2  each have the claw N that is a wire body catching portion for locking the optical fiber F, and the bobbin pivoting mechanism  120  further includes the bobbin selection mechanism  150  for setting the bobbins B 1  and B 2  around which the optical fiber F is to be wound, and the cutter  160  that is a wire body cleaving mechanism for cleaving the optical fiber F locked to the bobbins B 1  and B 2 . 
     The claw N may not be directly attached to the bobbins B 1  and B 2 , and may be attached to, for example, a cover that covers a flange of a bobbin. 
     Accordingly, an end portion of the optical fiber F can be locked and wound around the bobbins B 1  and B 2  that were set by the bobbin selection mechanism  150 . 
     A bobbin around which the optical fiber F is to be wound is set by the bobbin selection mechanism  150 , so that the optical fiber F can be wound around another bobbin without reducing a wire body speed. Therefore, the optical fiber F can be continuously wound without loss. 
     The wire body holding mechanism  140  is at least one of a suction nozzle for suctioning the optical fiber F or a pinch roller for pinching the wire body, so that the optical fiber can be reliably held at the time of being pulled out. 
     A moving speed of the wire body holding mechanism  140  is slower than a wire body pulling out speed of the optical fiber F, so that the optical fiber supplied from the optical fiber base material side is not insufficient. Therefore, the optical fiber F is not strongly pulled by the wire body holding mechanism  140  during a movement of the wire body holding mechanism  140  and the optical fiber F is not broken, and the optical fiber F can be efficiently wound around the bobbins B 1  and B 2 . 
     [Details of Second Embodiment of Present Disclosure] 
     Next, a specific structure of a wire body winding device  200  according to a second embodiment of the present disclosure will be described with reference to  FIGS. 3A to 3B . 
       FIG. 3A  is a plan cross-sectional view showing the wire body winding device according to the second embodiment of the present disclosure.  FIG. 3B  is an IIIB-IIIB cross-sectional view showing main parts in  FIG. 3A . 
     In the winding device  200  according to the second embodiment, a configuration of the first guide rail  111   b  and a structure of the wire body moving mechanism  130  in the winding device  100  according to the first embodiment are changed, and most components are the same as those in the winding device  100  according to the first embodiment. Therefore, detailed description for the same matters are omitted, and 200-series reference numbers with the same last two digits are attached. 
     In addition, since a wire body winding method using the winding device  200  is the same as that according to the first embodiment, description thereof will be omitted. 
     A first frame  211  of the winding device  200  is provided with the first guide rail  211   b  having a C-shaped cross section. 
     The first guide rail  211   b  is provided below a second guide rail  211   c  that extends in the left-right direction. 
     The first guide rail  211   b  includes a horizontal portion  211   ba  that extends in a horizontal direction, a vertical portion  211   bb  that extends in the vertical direction, and a bent portion  211   bc  that smoothly connects the horizontal portion  211   ba  and the vertical portion  211   bb.    
     A wire body moving mechanism  230  in the winding device  200  includes a roller  231  that travels on the first guide rail  211   b , an arm  232  that is coupled to the roller  231  and extends in the front-rear direction, and a holding member  233  that is coupled to a front end of the arm  232 . 
     The holding member  233  is a member that extends in the vertical direction, a lower end side of the holding member  233  is coupled to the arm  232 , and an upper end side of the holding member  233  holds a wire body holding mechanism  240 .
