The present application claims priority from Japanese Patent Application NO. 2019-090694 filed on May 13, 2019, contents of which are incorporated by reference in its entirety.
In the related art, a winding device that includes a wire body taking up portion, a wire body catching portion, and a wire body cleaving portion is known as a winding machine that winds an optical fiber around a bobbin. (for example, see Patent Literature 1).
Patent Literature 1: JP-A-2005-219855
According to one aspect of the present disclosure, 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.
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.
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.
According to the present disclosure, it is possible to automatically and easily wind a wire body around a bobbin.
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.
Hereinafter, a specific structure of a wire body winding device 100 and a wire body winding method using the winding device 100 according to a first embodiment of the present disclosure will be described with reference to
In the following description, configurations denoted by the same reference numerals in different drawings are the same, and description thereof may be omitted.
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
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 B1 and B2 as shown in
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 121b which will be described later is formed in one flange.
As shown in
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 B1 and B2 are disposed between the first frame 111 and the second frame 112.
A first guide rail 111b and a second guide rail 111c that extend in a left-right direction are provided on a front surface 111a of the first frame 111.
A cross-sectional shape of the first guide rail 111b and the second guide rail 111c is, for example, a circular shape as shown in
The first guide rail 111b is provided above the second guide rail 111c. Further, a length of the first guide rail 111b in the left-right direction is shorter than a length of the second guide rail 111c in the left-right direction.
[Bobbin Pivoting Mechanism]
The bobbin pivoting mechanism 120 includes a first bobbin pivoting mechanism 120A that pivots the bobbin B1 and a second bobbin pivoting mechanism 120B that pivots the bobbin B2.
A pivoting direction of the bobbin B1 by the first bobbin pivoting mechanism 120A is clockwise in a front view, and a pivoting direction of the bobbin B2 by the second bobbin pivoting mechanism 120B is counterclockwise in a front view.
The first bobbin pivoting mechanism 120A and the second bobbin pivoting mechanism 120B have the same structure, and thus only the first bobbin pivoting mechanism 120A will be described below.
The first bobbin pivoting mechanism 120A includes, in the first frame 111, a rotation shaft 121 of which one end is inserted into one end side of the bobbin B1 to drive the bobbin B1, a bearing 122 that supports a load of the bobbin B1 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 120A includes, in the second frame 112, a support shaft 125 that is inserted into the other end side of the bobbin B1 and supports the bobbin B1, a sleeve 126 that covers the support shaft 125, and a bearing 127 that supports a load of the bobbin B1 on the sleeve 126 (the support shaft 125).
The rotation shaft 121 is inserted into the bobbin B1 at a front end side, and a pulley 121a is press-fitted to a rear end side of the rotation shaft 121.
The transmission belt 124 is hung on the pulley 121a.
A kere pin 121b 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 B1, the kere pin 121b is inserted into the engagement hole H of the bobbin B1.
Accordingly, the bobbin B1 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 B1 and B2 can be attached to the winding device 100 or the bobbins B1 and B2 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
The horizontal slide portion 131 includes a slide member 131a through which the first guide rail 111b is inserted and that is movable on the first guide rail 111b, an arm 131b of which a rear end is connected to a front side of the slide member 131a and that extends forward, and a coupling member 131c to which a front end of the arm 131b is connected and that is coupled to the vertical slide portion 132.
The vertical slide portion 132 includes a guide shaft 132a that extends in the vertical direction and is inserted through the coupling member 131c, and a guide shaft holding member 132b that has a rectangular parallelepiped shape and is provided at a lower end of the guide shaft 132a.
The wire body holding mechanism 140 is held on a rear surface of the guide shaft holding member 132b.
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 P1 where the optical fiber can be held at the time of starting to be pulled out and a wire body winding position P2 where the optical fiber can be wound around the bobbins B1 and B2, as shown in
Here, the take-up position P1 refers to a position at a left end side of the first frame 111, and the wire body winding position P2 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 P2 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 111c, 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
As shown in
When the pull-out portion FL of the optical fiber F is held by the wire body holding mechanism 140, as shown in
Thereafter, as shown in
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 P1 to the wire body winding position P2.
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 B1, as shown in
A cross-sectional plan view of the winding device 100 at this time is
Next, as shown in
At this time, the optical fiber F comes into contact with a flange of the bobbin B1.
In this state, the bobbin B1 is rotated.
Accordingly, as shown in
When the bobbin B1 is further rotated, the optical fiber F is pressed against the cutter 160, and the optical fiber F is cleft as shown in
Thereafter, winding of the optical fiber F around the bobbin B1 is started.
A procedure of winding the pull-out portion FL of the optical fiber F around the bobbin B1 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 B2 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 P2 and then aligned to the bobbin B2 side.
[Switching of Winding Bobbins]
Next, switching of bobbins for winding the optical fiber will be described with reference to
When the winding of the optical fiber F around the bobbin B1 is started from the state shown in
Then, the bobbin B2 is rotated, so that the optical fiber F is caught by a claw N, and the optical fiber F is locked to the bobbin B2.
When the bobbin B2 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 B2 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 P1 where the optical fiber F that is a wire body can be held and the wire body winding position P2 where the optical fiber F can be wound around the bobbins B1 and B2.
When the wire body holding mechanism 140 holds the optical fiber F and moves from the take-up position P1 to the wire body winding position P2, an operator can wind the optical fiber F around the bobbins B1 and B2 only by holding the optical fiber F in the wire body holding mechanism 140, and a winding operation around the bobbins B1 and B2 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 B1 and B2 and drives each of the bobbins B1 and B2, 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 B1 and B2 and supports each of the bobbins B1 and B2, so that the bobbins B1 and B2 can be supported from both sides, and support strength of the bobbins B1 and B2 is increased. Therefore, even when the bobbins B1 and B2 have a large size, both of the bobbins B1 and B2 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 P2, so that the winding operation can be performed automatically and easily even when the bobbins B1 and B2 have a double-sided structure.
The bobbins B1 and B2 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 B1 and B2 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 B1 and B2.
The claw N may not be directly attached to the bobbins B1 and B2, 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 B1 and B2 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 B1 and B2.
