Description

[Technical Field]

[0001] The present disclosure relates to a wire winding device and a wire winding method. [Background technology]

[0002] Conventionally, when continuously feeding a wire such as an electric wire or an optical fiber onto a bobbin at high speed, the winding is switched from a full bobbin that has completed winding a predetermined amount to an empty bobbin that is ready for new winding without interrupting the running of the wire. The empty bobbin is rotated to start winding a new wire, while the full bobbin is stopped from rotating. However, the full bobbin cannot be stopped immediately due to inertia in its rotation, and continues to rotate, albeit at a slower speed to some extent.

[0003] At this time, the cut end of the wire on the fully wound bobbin side is released from tension and becomes free to swing around the bobbin. This causes a condition known as wire beating, in which the end of the wire hits the wound wire and strikes the surface of the winding. This wire beating occurs frequently during high-speed winding, and particularly when the wire is optical fiber, the wound optical fiber is damaged, weakening the optical fiber or breaking it. This results in waste, as the wound optical fiber must be discarded and extra optical fiber must be wound to accommodate the discarded portion.

[0004] As a means for preventing this wire beating, Patent Document 1 discloses a method for winding a wire onto a bobbin in which the pass line of the wire on the bobbin is covered by an annular guide (wire beating cover) having a notch for guiding the wire as it is wound onto the bobbin. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-200114 Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Document 1, an annular guide is disposed around the entire circumference of the bobbin to prevent the end of a broken wire from hitting the wire wound around the winding bobbin that becomes the product. However, because the annular guide has a notch for guiding the wire, there is a possibility that the end of the wire may enter the annular guide through the notch, causing wire beating.

[0007] Therefore, an object of the present disclosure is to provide a wire winding device and a wire winding method that can prevent wire beating and improve productivity. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0012] (Description of Embodiments of the Present Disclosure) First, embodiments of the present disclosure will be listed and described. A winding device for a wire body according to one aspect of the present disclosure includes: (1) a bobbin for winding the wire; a moving member that holds the wire before being wound onto the bobbin and is capable of moving the wire between a pass line and an outside of the pass line; Equipped with The moving member moves the wire under a predetermined condition so that at least an end of the wire is positioned outside the pass line. According to this configuration, by moving (evacuating) the wire outside the pass line under predetermined conditions, it is possible to prevent wire beating. This reduces the number of defective wires wound onto the bobbin, improving productivity. In addition, since wire beating does not occur even if the wire is cut at the same production line speed, it also leads to further cost reduction.

[0013] (2) The predetermined conditions may include at least one of the following: when the position of the dancer roller that controls the winding tension of the wire falls outside a predetermined range; when a break in the wire is detected from an image capturing the running state of the wire; when the tension of the wire falls outside a predetermined range; and when an earthquake of a predetermined seismic intensity or greater occurs. According to this configuration, when the wire body is cut (disconnected) or there is a high possibility that the wire body will be cut (disconnected), the wire body is moved outside the pass line, thereby reliably preventing wire beating.

[0014] (3) The moving member has an arm portion extending along the moving direction of the moving member and a bent portion bent at a tip end of the arm portion, The bent portion may be capable of holding the filament. According to this configuration, the end of the wire can be moved outside the pass line with a simple configuration.

[0015] (4) The bent portion may have a groove capable of receiving the filament. According to this configuration, the bent portion can hold the filament more securely.

[0016] (5) The moving member has a roller, The moving member can move to the outside of the pass line, The end portion of the wire may be wound around the roller before or simultaneously with the movement of the moving member to the outside of the pass line. According to this configuration, even if the cut wire swings around the bobbin, the wire can be reliably held and moved out of the pass line.

[0017] (6) The moving member has a suction portion, The moving member can move to the outside of the pass line, The end of the filament may be attracted to the suction portion before or simultaneously with the movement of the moving member to the outside of the pass line. According to this configuration, even if the cut wire swings around the bobbin, the wire can be reliably held and moved out of the pass line.

[0018] (7) Further comprising an end collection unit provided outside the pass line, The end collection unit may be configured to collect the wire that has been moved to the outside of the pass line by the moving member. This configuration can prevent the end of the wire that has been moved outside the pass line from returning to the pass line and causing wire beating.

[0019] (8) The end collecting unit may be integrated with the bobbin and collect the filament by rotating together with the bobbin. This configuration can more reliably prevent wire beating.

[0020] (9) The terminal collecting unit may have a suction mechanism that sucks the striatum. This configuration can more reliably prevent wire beating.

[0021] Furthermore, a method for winding a wire according to an embodiment of the present disclosure includes the steps of: (10) A method for winding a wire onto a bobbin, comprising the steps of: Under predetermined conditions, the wire is moved from the pass line so that at least the end of the wire is positioned outside the pass line of the wire when being wound onto the bobbin. According to this method, by moving the wire outside the pass line under predetermined conditions, it is possible to prevent wire beating, thereby suppressing defective products of the wire wound onto the bobbin and improving productivity.

[0022] (11) The predetermined conditions may include at least one of the following: when the position of a dancer roller that controls the winding tension of the wire falls outside a predetermined range; when a break in the wire is detected from an image capturing the running state of the wire; when the tension of the wire falls outside a predetermined range; and when an earthquake of a predetermined seismic intensity or greater occurs. According to this method, when the wire is cut (disconnected) or there is a high possibility that the wire will be cut (disconnected), the wire is moved out of the pass line, thereby reliably preventing wire beating.

[0023] (12) The filament may be cut while maintaining the manufacturing wire speed during drawing of the filament. According to this method, even if the filament is cut at the same production wire speed as when it was drawn, no wire beating occurs, which greatly improves the efficiency of the winding work for the filament, leading to cost reduction.

[0024] (Details of the embodiments of the present disclosure) Specific examples of a wire winding device and a wire winding method according to embodiments of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to these examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0025] 1 and 2 are diagrams illustrating the winding of an optical fiber G (an example of a wire) by the winding device 1 of this embodiment. FIG. 3 is a diagram illustrating a moving member and an end collecting unit of the winding device 1 of this embodiment. FIG. 4 is a diagram illustrating the collection of the optical fiber G by the end collecting unit. In this embodiment, for convenience of explanation, the "left-right direction," "up-down direction," and "front-rear direction" may be referred to as appropriate. These directions are relative directions set for the winding device 1 shown in FIG. 1 etc. Here, the "left-right direction" is a direction that includes the "left direction" and the "right direction." The "up-down direction" is a direction that includes the "upward direction" and the "downward direction." The "front-rear direction" is a direction that includes the "forward direction" and the "rearward direction." Although not shown in FIGS. 1 and 2, the left-right direction is a direction that is perpendicular to the up-down direction and the front-rear direction.

[0026] 1 to 4, the winding device 1 includes a first bobbin 2a, a second bobbin 2b, a guide roller 3, claw wheels 4 (4a, 4b), locking claws 5 (5a, 5b), fiber cutters 9 (9a, 9b), a cut detection unit 10, movable members 20 (20a, 20b), and end collection units 30 (30a, 30b). For simplicity of illustration, the cut detection unit 10 and movable members 20 (20a, 20b) of the winding device 1 are omitted from FIG.

[0027] First, with reference to Figures 1 and 2, the winding of the optical fiber G when switching the winding bobbin for the optical fiber G will be described. The winding device 1 has, for example, a first bobbin 2a in one winding unit (rear side in Figures 1 and 2) and a second bobbin 2b in the other winding unit (front side in Figures 1 and 2). Hereinafter, the first bobbin 2a and the second bobbin 2b will also be collectively referred to as bobbins 2 (2a, 2b).

[0028] Claw wheels 4 (4a, 4b) are detachably attached to one side of the bobbin flanges of each of the bobbins 2 (2a, 2b). The claw wheels 4 (4a, 4b) are provided with locking claws 5 (5a, 5b) that can grip and lock the winding start end of the optical fiber G. In addition, fiber cutters 9 (9a, 9b) for cutting the optical fiber G are provided between the first bobbin 2a and the second bobbin 2b.

[0029] 1 shows a state in which the optical fiber G on the first bobbin 2a side is fully wound or has finished winding, and the guide roller 3 is traversed from the central home position (chain line position H) to the empty second bobbin 2b side (in the direction of arrow S) in order to switch winding to the second bobbin 2b. By traversing the guide roller 3 to the second bobbin 2b side, the path line of the optical fiber G changes to a position close to or in contact with the second bobbin 2b.

[0030] When the path line of the optical fiber G changes to a position close to or in contact with the second bobbin 2b, the rotation of the first bobbin 2a is stopped. Meanwhile, the second bobbin 2b starts to rotate counterclockwise to start winding the optical fiber G onto the second bobbin 2b. At this point, the optical fiber G is not in contact with the second bobbin 2b. Next, the second bobbin 2b is moved in a direction perpendicular to the plane of the paper, and the path line is displaced so that the optical fiber G contacts the pawl wheel 4b of the second bobbin 2b. When the optical fiber G contacts the pawl wheel 4b, the winding start end of the optical fiber G is locked by the locking pawls 5b provided on the pawl wheel 4b.

[0031] When the optical fiber G is locked by the locking claws 5b of the claw wheel 4b due to the counterclockwise rotation of the second bobbin 2b, the optical fiber G moves together with the locking claws 5b and is pulled. Further, as the second bobbin 2b continues to rotate, the optical fiber G comes into contact with the fiber cutter 9b and is cut. This sets the optical fiber G free, and a new winding operation begins as the second bobbin 2b is driven to rotate. The end of the optical fiber G locked by the locking claws 5b of the claw wheel 4b is held as the winding start end until winding is completed.

[0032] 2 shows a state in which the optical fiber G is cut (disconnected) for some reason midway along the pass line PL during a winding operation. The cut detection unit 10 of the winding device 1 is a detection unit that detects that the optical fiber G wound around the bobbin 2 (2a, 2b) has been cut (disconnected). The cut detection unit 10 has, for example, a dancer roller 11 that can adjust the tension of the optical fiber G, a position detection sensor 12 that detects the amount of movement of the dancer roller 11, and a cut control unit 16 that controls each part of the cut detection unit 10. The cut detection unit 10 may also include a camera 13 that captures an image of the running state of the optical fiber G, a tension sensor 14 that detects the tension of the running optical fiber G, a seismic intensity meter 15 that measures the seismic intensity when an earthquake occurs, and the like.

[0033] The cutoff detection unit 10 detects the amount of movement of the dancer roller 11 using the position detection sensor 12 and transmits the detected amount of movement to the cutoff control unit 16. If the amount of movement of the dancer roller 11 is outside a predetermined range, the cutoff control unit 16 detects that an overload has been applied to the optical fiber G and that the optical fiber G has been cut. The cutoff detection unit 10 may also capture an image of the running state of the optical fiber G using the camera 13 and transmit the captured image to the cutoff control unit 16. In this case, the cutoff control unit 16 detects whether the optical fiber G has been cut based on the captured image. The cutoff detection unit 10 may also detect the tension of the optical fiber G using the tension sensor 14 and transmit the detected tension to the cutoff control unit 16. In this case, the cutoff control unit 16 detects that an overload has been applied to the optical fiber G and that the optical fiber G has been cut based on the fact that the tension of the optical fiber G has deviated from a predetermined range (for example, has decreased below the predetermined range). The cutoff detection unit 10 may also measure seismic motion using a seismic intensity meter 15 and transmit the measured seismic intensity to the cutoff control unit 16. In this case, the disconnection control unit 16 detects that the optical fiber G has been disconnected (or that there is a high possibility that it will be disconnected) based on the occurrence of an earthquake with a predetermined seismic intensity or greater.

[0034] The cutting control unit 16 is communicatively connected to the movable members 20 (20a, 20b), and transmits cutting information regarding the cutting of the optical fiber G received from the position detection sensor 12, etc., to the movable members 20 (20a, 20b). The cutting control unit 16 is configured to control the operation of the movable members 20 (20a, 20b) based on the cutting information.

[0035] The disconnection control unit 16 may be implemented by a general-purpose microprocessor operating in cooperation with general-purpose memory. Examples of general-purpose microprocessors include a CPU, an MPU, and a GPU. Examples of general-purpose memory include a ROM and a RAM. In this case, a computer program for executing the above-described process may be stored in the ROM. The ROM is an example of a storage medium for storing a computer program. The processor selects at least a portion of the computer program stored in the ROM, deploys it on the RAM, and executes the above-described process in cooperation with the RAM. The computer program may be pre-installed in the general-purpose memory or may be downloaded from an external server via a communication network and installed in the general-purpose memory. In this case, the external server is an example of a storage medium for storing a computer program. The disconnection control unit 16 may be implemented by a dedicated integrated circuit capable of executing the computer program, such as a microcontroller, an ASIC, or an FPGA. In this case, the computer program is pre-installed in a memory element included in the dedicated integrated circuit. The memory element is an example of a storage medium for storing a computer program. The disconnection control unit 16 may also be implemented by a combination of a general-purpose microprocessor and a dedicated integrated circuit.

[0036] Next, a method for collecting the end of the optical fiber G when the cut detection unit 10 detects a cut in the optical fiber G will be described with reference to Figures 3 and 4. Figures 3 and 4 are views of, for example, the bobbin 2a of the bobbins 2 (2a, 2b) in Figure 1 around which the optical fiber G is wound, as viewed from above. For ease of explanation, the bobbin collar on the left side of the bobbin 2 (2a, 2b) in Figure 1 has been removed.

[0037] As shown in Figures 3 and 4, the movable member 20a of the winding device 1 is provided near the bobbin 2a. The end collecting unit 30a is provided so as to protrude from one of the bobbin flanges of the bobbin 2a. In this example, the end collecting unit 30a is provided so as to protrude leftward from the left bobbin flange of the bobbin 2a. The movable member 20a is a member that holds the optical fiber G before it is wound onto the bobbin 2a and moves the position of the optical fiber G. The end collecting unit 30a is a collecting unit that collects the optical fiber G moved by the movable member 20a. The movable member 20b and the end collecting unit 30b are disposed in the same manner with respect to the bobbin 2b, and have the same configuration as the movable member 20a and the end collecting unit 30a. Therefore, in the following explanation, only the movable member 20a and the end collecting unit 30a will be explained.

[0038] The moving member 20a has an arm 21a, a bending portion 22a provided at the tip of the arm 21a, and a driving portion 23a that controls the operation of each portion of the moving member 20a.

[0039] The moving member 20a is configured to be able to reciprocate relative to the bobbin 2a in the direction of the rotation axis of the bobbin 2a (the direction of arrow A in FIG. 3). The moving member 20a is configured, for example, so that the bending portion 22a can move at least within a range that straddles the path line PL of the optical fiber G. The moving member 20a is configured, for example, so that the bending portion 22a can move outward from the bobbin collar on the side of the bobbin 2a where the end collecting portion 30a is provided, that is, outward from the path line PL. The operation of the moving member 20a is controlled by a driving unit 23a.

[0040] Arm 21a extends along the movement direction of moving member 20a (the direction of arrow A in FIG. 3). One end of arm 21a is connected to drive unit 23a, and the other end is provided with bent portion 22a. Arm 21a is configured to be rotatable around an axis extending in the longitudinal direction of arm 21a under the control of drive unit 23a.

[0041] The bending portion 22a is configured to be able to hook and hold the optical fiber G that moves within the width of the pass line PL. The bending portion 22a is provided so as to protrude in a direction perpendicular to the longitudinal direction of the arm portion 21a. The bending portion 22a is configured to hook and hold the optical fiber G by linear movement of the moving member 20a in the direction of the rotation axis of the bobbin 2a and in a direction perpendicular to the rotation axis of the bobbin 2a, and rotational movement of the arm portion 21a.

[0042] While the optical fiber G is being wound around the bobbin 2a, the moving member 20a is made to wait at a position where it does not come into contact with the optical fiber G being wound. Furthermore, the moving member 20a is made to wait at a position where the optical fiber G can be hooked onto the bending portion 22a more quickly when cutting the optical fiber G. Specifically, while the optical fiber G is being wound around the bobbin 2a, the moving member 20a is made to wait, for example, with the bending portion 22a positioned beyond the bobbin collar on the side of the bobbin 2a where the end collection unit 30a is not provided (the position of the bending portion 22a indicated by the two-dot chain line on the right side in FIG. 3). Furthermore, when cutting the optical fiber G, the moving member 20a is configured to move the optical fiber G, which is hooked and held onto the bending portion 22a, to the left of the bobbin collar on the left side (the side where the end collection unit 30a is provided), i.e., to the outside of the pass line PL.

[0043] The end collecting unit 30a is provided on the bobbin 2a so as to protrude outside the path line PL of the optical fiber G. The end collecting unit 30a is provided integrally with the bobbin 2a. The end collecting unit 30a has a tubular portion 31a around which the optical fiber G is wound, and a flange portion 32a that prevents the optical fiber G wound around the tubular portion 31a from coming off. As shown in FIG. 4, the end collecting unit 30a is configured to collect, from the moving member 20a, the optical fiber G that has been moved to the outside of the path line PL by the moving member 20a. The end collecting unit 30a is configured to rotate together with the bobbin 2a, thereby winding and collecting the optical fiber G held by the moving member 20a around the tubular portion 31a.

[0044] Next, the winding operation of the winding device 1 for the optical fiber G when the optical fiber G is cut will be described. The cut detection unit 10 detects the amount of movement of the dancer roller 11, for example, using a position detection sensor 12, and transmits the detected amount of movement to the cut control unit 16. The cut control unit 16 compares the received amount of movement with a predetermined allowable amount of movement, and determines that the optical fiber G is cut if the amount of movement of the dancer roller 11 exceeds the allowable amount of movement. The position detection sensor 12 may be, for example, an encoder.

[0045] When the cutting control unit 16 determines that the optical fiber G has been cut, it transmits cutting information about the optical fiber G to the driving unit 23a of the moving member 20a. As described above, the moving member 20a is on standby while the optical fiber G is being wound onto the bobbin 2a, with the bending portion 22a positioned at the position indicated by the two-dot chain line on the right side in FIG. 3. At this time, it is preferable that the driving unit 23a rotates the arm 21a to adjust the position of the bending portion 22a so that the bending portion 22a does not obstruct the path line PL of the optical fiber G.

[0046] When the drive unit 23a receives information about the cutting of the optical fiber G, it rotates the arm 21a to move the bending portion 22a to a position where the optical fiber G can be hooked, and moves the entire moving member 20a toward the direction (leftward) where the terminal collection portion 30a on the bobbin 2a is provided, so that the optical fiber G before being wound onto the bobbin 2a is hooked onto and held in the bending portion 22a.

[0047] Next, the driving section 23a moves the moving member 20a further to the left, and moves the optical fiber G held by the bending section 22a to the left outside of the path line PL.

[0048] When the optical fiber G is moved toward the end collecting unit 30a by the moving member 20a, the end collecting unit 30a, which rotates together with the bobbin 2a, winds the optical fiber G held at the bending portion 22a around the tubular portion 31a of the end collecting unit 30a. As a result, the end of the cut optical fiber G is collected in the end collecting unit 30a. Note that when the cutting control unit 16 determines that the optical fiber G has been cut, the bobbin 2a and the end collecting unit 30a may, for example, stop rotating. However, as described above, the bobbin 2a cannot immediately stop due to inertia in its rotation, and continues to rotate, albeit at a decelerated speed to some extent. As a result, the end collecting unit 30a rotates together with the bobbin 2a, which continues to rotate, and the optical fiber G moved toward the end collecting unit 30a by the moving member 20a is wound around the tubular portion 31a of the end collecting unit 30a.

[0049] As described above, the winding device 1 of this embodiment includes the bobbins 2 (2a, 2b) that wind the optical fiber G, and the movable members 20 (20a, 20b) that hold the optical fiber G before it is wound onto the bobbins 2 (2a, 2b) and move the optical fiber G between the pass line PL and the outside of the pass line PL. The movable members 20 (20a, 20b) detect that the optical fiber G has been severed when, for example, the movement amount of the dancer roller 11 detected by the position detection sensor 12 is outside a predetermined range, and move the optical fiber G so that at least the end of the optical fiber G is positioned outside the pass line PL. This configuration prevents the occurrence of wire tapping due to the severed optical fiber G by moving the optical fiber G outside the pass line PL under predetermined conditions, such as when the movement amount of the dancer roller 11 is outside the predetermined range. This reduces product defects in the optical fiber G wound onto the bobbins 2 (2a, 2b), thereby improving productivity. Specifically, for example, the amount of discarded optical fiber G that has become a defective product can be reduced by approximately 50% compared to the conventional method.

[0050] In addition to the movement amount of the dancer roller 11, the optical fiber G may be moved so that at least the end of the optical fiber G is located outside the pass line PL under conditions such as when a cut in the optical fiber G is detected from an image capturing an image of the running state of the optical fiber G, when the tension in the optical fiber G falls outside a predetermined range, or when an earthquake of a predetermined seismic intensity or higher occurs. In this way, when the optical fiber G is cut (disconnected) or there is a high possibility that the optical fiber G will be cut (disconnected), the optical fiber G can be moved outside the pass line PL, and the occurrence of wire tapping can be reliably prevented.

[0051] Furthermore, the moving members 20 (20a, 20b) have arm portions 21 (21a, 21b) extending along the moving direction of the moving members 20 (20a, 20b) and bent portions 22 (22a, 22b) bent at the tips of the arm portions 21 (21a, 21b). The winding device 1 according to this embodiment is configured so that the optical fiber G before being wound onto the bobbin 2 (2a, 2b) can be hooked and held by the bent portions 22 (22a, 22b) of the moving members 20 (20a, 20b). This makes it possible to move the end of the optical fiber G outside the pass line PL with a simple configuration, thereby preventing wire beating.

[0052] Furthermore, according to the winding device 1 of this embodiment, the optical fiber G moved to the outside of the pass line PL by the moving members 20 (20a, 20b) is collected by the end collecting unit 30a. This makes it possible to prevent the end of the optical fiber G moved to the outside of the pass line PL from returning to the inside of the pass line PL, thereby reliably preventing wire beating.

[0053] Furthermore, in this embodiment, as a winding method for the optical fiber G, a method is executed in which, under predetermined conditions, the optical fiber G is moved from the pass line PL so that at least an end of the optical fiber G is positioned outside the pass line PL of the optical fiber G when it is wound around the bobbin 2 (2a, 2b). According to this method, similar to the winding device 1 described above, it is possible to prevent wire beating, suppress product defects in the optical fiber G wound around the bobbin 2, and improve productivity.

[0054] (First Modification) Next, a first modified example of the moving member in the winding device 1 will be described with reference to FIG. As shown in Fig. 5, the moving members 120 (120a, 120b) of the first modified example have arms 121 (121a, 121b), bent portions 122 (122a, 122b) provided at the distal ends of the arms 121 (121a, 121b), and driving portions 123 (123a, 123b) that control the operation of each portion of the moving members 120 (120a, 120b). Fig. 5 is a front view of the moving members 120 (120a, 120b) provided near the bobbins 2 (2a, 2b).

[0055] The bending portions 122 (122a, 122b) of the moving member 120 (120a, 120b) have groove portions 124 (124a, 124b) capable of receiving the optical fiber G. The groove portions 124 (124a, 124b) are formed, for example, in a V-shape. The bending portions 122 (122a, 122b) are configured so that the optical fiber G, which moves within the width of the path line PL, can be received and held in the groove portions 124 (124a, 124b).

[0056] The movement direction, movement range, and standby position of the movable members 120 (120a, 120b) are the same as those of the movable members 20 (20a, 20b) in the above embodiment. The configuration of the arm portions 121 (121a, 121b) is the same as that of the arm portions 21 (21a, 21b) in the above embodiment. The operation control of the movable members 120 (120a, 120b) by the drive portions 123 (123a, 123b) is the same as that by the drive portions 23 (23a, 23b) in the above embodiment.

[0057] When the optical fiber G is cut, the moving member 120 (120a, 120b) receives and holds the end of the cut optical fiber G before it is wound onto the bobbin 2a in the groove portion 124 (124a, 124b) of the bending portion 122 (122a, 122b), and moves it to the outside of the path line PL (towards the end collection portion 30 (30a, 30b)).

[0058] According to the moving member 120 (120a, 120b) of the first modified example, the bending portion 122 (122a, 122b) has the groove portion 124 (124a, 124b) capable of receiving the optical fiber G, so that the optical fiber G can be held more reliably.

[0059] (Second Modification) Next, a second modified example of the moving member in the winding device 1 will be described with reference to FIG. As shown in Fig. 6, the moving members 220 (220a, 220b) of the second modified example have arms 221 (221a, 221b), rollers 222 (222a, 222b) provided at the tips of the arms 221 (221a, 221b), and drivers 223 (223a, 223b) that control the operation of each part of the moving members 220 (220a, 220b). Note that Fig. 6 is a view of the moving members 220 (220a, 220b) as seen from the front, similar to the first modified example.

[0060] The rollers 222 (222a, 222b) of the moving member 220 (220a, 220b) are grooved rollers having grooves 224 (224a, 224b) capable of receiving the optical fiber G. The grooves 224 (224a, 224b) are formed, for example, in a V-shape. The rollers 222 (222a, 222b) are configured to receive and hold the optical fiber G moving within the width of the pass line PL in the grooves 224 (224a, 224b). The rollers 222 (222a, 222b) rotate around a rotation axis along the longitudinal direction of the arm portions 221 (221a, 221b). As a result, the rollers 222 (222a, 222b) are configured to wind the optical fiber G received in the grooves 224 (224a, 224b).

[0061] The movement direction, movement range, and standby position of the movable members 220 (220a, 220b) are the same as those of the movable members 20 (20a, 20b) in the above embodiment. The configuration of the arm portions 221 (221a, 221b) is the same as that of the arm portions 21 (21a, 21b) in the above embodiment. The operation control of the movable members 220 (220a, 220b) by the drive portions 223 (223a, 223b) is the same as that by the drive portions 23 (23a, 23b) in the above embodiment.

[0062] The moving member 220 (220a, 220b) configured as described above operates, for example, as follows. When the drive unit 223 (223a, 223b) receives cut information of the optical fiber G from the cut detection unit 10, it moves the moving member 220 (220a, 220b) and receives and holds the cut optical fiber G in the groove portion 224 (224a, 224b) of the roller 222 (222a, 222b) before it is wound onto the bobbin 2a. Next, the driving units 223 (223a, 223b) move the moving members 220 (220a, 220b) to move the optical fiber G held in the grooves 224 (224a, 224b) to the outside of the path line PL (toward the end collection units 30 (30a, 30b)). At this time, the driving units 223 (223a, 223b) start the rotation of the rollers 222 (222a, 222b) together with the start of movement of the moving members 220 (220a, 220b), and wind the optical fiber G held in the grooves 224 (224a, 224b) around the rollers 222 (222a, 222b). The end of the optical fiber G moved to the terminal collection section 30a is wound around the cylindrical portion 31a of the terminal collection section 30a, which rotates together with the bobbin 2a, and is collected from the rollers 222 (222a, 222b) of the moving member 220 (220a, 220b) into the cylindrical portion 31a of the terminal collection section 30a.

[0063] According to the moving members 220 (220a, 220b) of the second modified example, the rollers 222 (222a, 222b) are rotated while the moving members 220 (220a, 220b) are moved outward from the pass line PL, thereby making it possible to wind the end of the cut optical fiber G around the rollers 222 (222a, 222b). Therefore, even if the cut optical fiber G swings around inside the winding device 1, the optical fiber G can be reliably held and moved outward from the pass line PL.

[0064] (Third Modification) Next, a third modified example of the moving member in the winding device 1 will be described with reference to FIG. As shown in FIG. 7, the moving members 320 (320a, 320b) of the third modified example include arm portions 321 (321a, 321b), rollers 322 (322a, 322b) provided at the distal ends of the arm portions 321 (321a, 321b), and driving units 323 (323a, 323b) that control the operation of each unit of the moving members 320 (320a, 320b). Similar to the first and second modified examples, FIG. 7 is a front view of the moving members 320 (320a, 320b). However, compared to the moving members 220 (220a, 220b) of the second modified example shown in FIG. 6, the moving members 320 (320a, 320b) are arranged such that the orientation of the moving members 320 (320a, 320b) with respect to the optical fiber G is rotated by 90 degrees.

[0065] The rollers 322 (322a, 322b) of the moving member 320 (320a, 320b) are rod-shaped rollers. The rollers 322 (322a, 322b) are configured to rotate so as to wind the optical fiber G, which moves at the width of the pass line PL. When the moving member 320 (320a, 320b) moves the optical fiber G wound around the rollers 322 (322a, 322b) to the outside of the pass line PL (toward the end collection unit 30 (30a, 30b)), the moving member 320 (320a, 320b) moves in the direction of arrow B (the direction of the rotation axis of the bobbin 2a) in FIG. 7. Note that in the example shown in FIG. 7, the arm portions 321 (321a, 321b) and the rollers 322 (322a, 322b) are configured independently, but, for example, both members may be integrated into one rod-shaped roller.

[0066] The movable member 320 (320a, 320b) of the third modified example can also wind the end of the cut optical fiber G around the rollers 322 (322a, 322b), just like the movable member 220 (220a, 220b) of the second modified example. Therefore, even if the cut optical fiber G swings around inside the winding device 1, the optical fiber G can be securely held and moved outside the pass line PL.

[0067] (Fourth Modification) Next, a fourth modified example of the moving member in the winding device 1 will be described with reference to FIG. As shown in Fig. 8, the movable members 420 (420a, 420b) of the fourth modified example have arms 421 (421a, 421b), suction units 422 (422a, 422b) provided at the tips of the arms 421 (421a, 421b), and drive units 423 (423a, 423b) that control the operation of each unit of the movable members 420 (420a, 420b). Note that Fig. 8 is a view of the movable members 420 (420a, 420b) as seen from the front, similar to the first modified example.

[0068] The suction portions 422 (422a, 422b) of the moving member 420 (420a, 420b) have opening grooves 424 (424a, 424b) capable of receiving the optical fiber G. The opening grooves 424 (424a, 424b) are formed, for example, in a V-shape. The suction portions 422 (422a, 422b) are configured to receive and hold the optical fiber G moving within the width of the path line PL in the opening grooves 424 (424a, 424b). Furthermore, the suction portions 422 (422a, 422b) are configured to perform a suction operation to suck the optical fiber G received in the opening grooves 424 (424a, 424b) into the suction portions 422 (422a, 422b).

[0069] The suction units 422 (422a, 422b) are configured to perform a suction operation of the optical fiber G based on the control of the drive units 423 (423a, 423b). Other configurations and operations of the moving members 420 (420a, 420b) are similar to those of the moving members 20 (20a, 20b) of the above embodiment.

[0070] The moving member 420 (420a, 420b) configured as described above operates, for example, as follows. When the drive unit 423 (423a, 423b) receives cut information of the optical fiber G from the cut detection unit 10, it moves the moving member 420 (420a, 420b) and receives and holds the end of the cut optical fiber G before it is wound onto the bobbin 2a in the opening groove portion 424 (424a, 424b) of the suction unit 422 (422a, 422b). Next, the driving units 423 (423a, 423b) move the moving members 420 (420a, 420b) to move the optical fibers G held in the opening grooves 424 (424a, 424b) to the outside of the path line PL (toward the end collection units 30 (30a, 30b)). At this time, the driving units 423 (423a, 423b) start the suction operation of the suction units 422 (422a, 422b) together with the start of movement of the moving members 420 (420a, 420b), and suck the optical fibers G held in the opening grooves 424 (424a, 424b) into the suction units 422 (422a, 422b). The end of the optical fiber G moved to the terminal collection section 30a is wound around the tubular portion 31a of the terminal collection section 30a, which rotates together with the bobbin 2a, and is collected into the tubular portion 31a of the terminal collection section 30a from the suction portion 422 (422a, 422b) of the moving member 420 (420a, 420b).

[0071] According to the fourth modified example of the movable member 420 (420a, 420b), by starting suction of the suction section 422 (422a, 422b) as the movable member 420 (420a, 420b) moves outward from the pass line PL, the end of the cut optical fiber G can be sucked into the suction section 422 (422a, 422b). Therefore, even if the cut optical fiber G swings around inside the winding device 1, the optical fiber G can be securely held and moved outward from the pass line PL.

[0072] (Modification of terminal collection unit) Next, a modified example of the end collecting section of the winding device 1 will be described with reference to FIG. 9, the terminal collection unit 130a according to this modification includes a cylindrical portion 131a around which the optical fiber G is wound, a flange portion 132a that prevents the optical fiber G wound around the cylindrical portion 131a from coming off, and a suction mechanism 133a that sucks the optical fiber G. The suction mechanism 133a includes a plurality of suction holes 134a formed on the side surface of the cylindrical portion 131a, and a suction unit 135a that controls the suction operation of the suction mechanism 133a.

[0073] The end collection unit 130a is configured to collect, from the moving member 20a, the optical fiber G that has been moved to the outside of the pass line PL by the moving member 20a. The end collection unit 130a rotates together with the bobbin 2a and sucks the optical fiber G using a suction mechanism 133a. The end collection unit 130a is configured to wind the optical fiber G held by the moving member 20a around the rotating cylindrical portion 31a and collect the wound optical fiber G by sucking it into the suction holes 134a.

[0074] According to the modified terminal collection unit 130a, the collected optical fiber G can be sucked in by the suction mechanism 133a, so that it is possible to reliably prevent the end of the optical fiber G that has been moved outside the pass line PL from returning back into the pass line PL and causing wire beating.

[0075] Although the present disclosure has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the present disclosure. Furthermore, the number, position, shape, etc. of the components described above are not limited to the above embodiments, and can be changed to the number, position, shape, etc. that are suitable for implementing the present disclosure.

[0076] The arm 21 is configured to be rotatable around an axis in the longitudinal direction of the arm 21 under the control of the drive unit 23, but is not limited to this example. For example, instead of or in addition to a configuration that rotates the arm 21, the moving member 20 may be configured to be movable in a direction perpendicular to the rotation axis direction of the bobbin 2 (up and down). In this case, while the optical fiber G is being wound onto the bobbin 2, the entire moving member 20 can be moved upward or downward to wait so that the bending portion 22 does not obstruct the path line PL of the optical fiber G. When cutting the optical fiber G, the moving member 20 is moved to a position where the bending portion 22 can hold the optical fiber G, and then further moved outside the path line PL, thereby reliably holding the optical fiber G and moving it outside the path line PL, as in the above embodiment.

[0077] In the above-described embodiment and modified example, a configuration has been mainly described in which the optical fiber G is held by the moving member 20 and collected in the end collecting unit 30 when the optical fiber G is unintentionally cut (disconnected) during winding, but the present invention is not limited to this example. For example, when switching winding from one bobbin 2 (e.g., one of the first bobbin 2a and the second bobbin 2b) to the other bobbin 2 (e.g., the other of the first bobbin 2a and the second bobbin 2b), the optical fiber G may be cut by the fiber cutters 9 (9a, 9b) while maintaining the manufacturing drawing speed during drawing, and the cut optical fiber G may be held by the moving member 20 and collected in the end collecting unit 30. With this configuration, no wire beating occurs even when the optical fiber G is cut by the fiber cutters 9 (9a, 9b) while maintaining the manufacturing drawing speed during drawing, and therefore, the efficiency of the optical fiber G winding operation can be significantly improved, enabling cost reduction. Furthermore, when completing the production of the optical fiber G, the optical fiber G may be cut by the fiber cutter 9 (9a, 9b) while maintaining the manufacturing drawing speed during drawing, and the cut optical fiber G may be held by the moving member 20 and collected in the terminal collection unit 30. With this configuration, there is no need to reduce the drawing speed to prevent the occurrence of wire beating, and production can be completed at the manufacturing drawing speed during drawing, thereby greatly improving production efficiency.
