[Description of Embodiment of the Present Invention]
First, embodiments of the present invention will be listed and described.
The manufacturing method of the optical fiber ribbon according to the embodiment of the present invention,
(1) A plurality of optical fiber cores are arranged in parallel to travel a pass line, and the plurality of optical fiber cores are brought into contact with an adhesive resin transport roller provided in the middle of the pass line to intermittently bond the adhesive resin. It is a manufacturing method for manufacturing an intermittently connected optical fiber ribbon that is intermittently connected to a desired shape by coating,
The adhesive resin transport roller includes a disk-shaped fiber roller having an opening in the vicinity of the center, a diameter larger than the fiber roller, and at least one resin coating hole in the vicinity of the peripheral edge and the vicinity of the center Disk-shaped partition plates provided with openings at the ends thereof, and disk-shaped guide rollers provided alternately so as to sandwich the outer surfaces of the fiber rollers at both ends and having openings near the center. Have
The opening portion of the fiber roller, the opening portion of the partition plate, and the opening portion of the guide roller constitute a resin filling portion, and the resin filling portion and the resin coating hole communicate with each other.
A filling step of filling the adhesive resin into the resin filling portion from the opening on the side surface of the guide roller by immersing the adhesive resin transport roller while rotating it in the uncured adhesive resin,
The optical fiber core wire is brought into contact with the partition plate so that the partition plate is sandwiched between the running optical fiber core wires, and the adhesive resin filled in the resin filling portion is discharged from the resin application hole. And applying to the optical fiber core wire,
Curing the adhesive resin;
including.

According to the manufacturing method of the optical fiber ribbon of the above (1), the traveling optical fiber core is brought into contact with the partition plate and the fiber roller, and the partition plate is provided with the resin coating hole. Adhesive resin is applied to the side surface of the optical fiber adjacent to the plate. For this reason, the adhesive resin can be intermittently applied between the optical fiber cores by bringing the part provided with the resin coating hole and the part not provided with the partition plate into contact with the optical fiber cores.
When the adhesive resin transport roller is immersed in the adhesive resin tank while rotating, the adhesive resin transport roller is rotated by filling the resin filling portion communicating with the opening of the guide roller on the side of the adhesive resin transport roller. Even it can be retained. Since the resin coating hole communicates with the resin filling portion, the adhesive resin can be reliably supplied to the resin coating hole even if the adhesive resin transport roller is rotated at a high speed. Accordingly, the intermittently connected optical fiber ribbon that is intermittently connected in a desired shape can be manufactured by running the optical fiber at a high speed, thereby shortening the manufacturing time and reducing the manufacturing cost.
In addition, since the position of the optical fiber core wire is fixed by the adhesive resin transport roller, a precise mechanism for increasing the positioning accuracy is not necessary. Further, since the adhesive resin is only supplied by immersing it in an uncured adhesive resin while rotating the adhesive resin transport roller, there is no need for a mechanism for intermittently supplying the adhesive resin. Thus, there is no need to provide a mechanism for increasing the manufacturing cost.

(2) In the manufacturing method of the optical fiber ribbon of (1), the adhesive resin transport roller is driven by power and rotates.
Since the adhesive resin transport roller is driven by power, the intermittent connection pitch can be arbitrarily changed without changing the diameter of the roller.

(3) In the method for manufacturing an optical fiber ribbon of (2), a sensor that detects a traveling speed of the optical fiber core is disposed on the upstream side of the pass line from the adhesive resin transport roller,
The rotational speed of the adhesive resin transport roller is controlled using information on the traveling speed detected by the sensor.
By detecting the running speed of the tape core and controlling the rotation speed of the adhesive resin transport roller based on that information, the desired intermittent connection pitch can be stabilized even if the running speed of the optical fiber core fluctuates. Can be realized.

(4) In the method for manufacturing an optical fiber ribbon of (1), the adhesive resin transport roller is not driven by power but rotates by friction between the optical fiber core and the roller.
By rotating the adhesive resin transfer roller by friction with the optical fiber core without being driven by power, slippage between the roller and the optical fiber core is minimized, and damage to the optical fiber core surface is suppressed. It is done. In addition, even if the traveling speed of the optical fiber core wire changes, the rotational speed of the roller also changes accordingly, so that the intermittent connection pitch is stabilized.

An apparatus for manufacturing an optical fiber ribbon according to an embodiment of the present invention,
(5) a disk-shaped fiber roller having an opening near the center;
A disk-shaped partition plate having a diameter larger than that of the fiber roller and having at least one resin coating hole in the vicinity of the peripheral edge and an opening in the vicinity of the center is alternately stacked, A disc-shaped guide roller provided so as to sandwich the outer surface of the fiber roller and having an opening in the vicinity of the center thereof, an adhesive resin transport roller,
An adhesive resin tank for storing the adhesive resin;
A resin curing device for curing the adhesive resin;
With
The fiber roller opening, the partition plate opening, and the guide roller opening communicate with each other to form a resin filling portion, and the resin filling portion and the resin coating hole communicate with each other.
An intermittently connected optical fiber ribbon that is intermittently connected in a desired shape is manufactured.

According to the optical fiber ribbon manufacturing apparatus of (5) above, the running optical fiber core is brought into contact with the partition plate and the fiber roller, and the partition plate is provided with the resin coating hole. Adhesive resin is applied to the side surface of the optical fiber adjacent to the plate. For this reason, the adhesive resin can be intermittently applied between the optical fiber cores by bringing the part provided with the resin coating hole and the part not provided with the partition plate into contact with the optical fiber cores.
When the adhesive resin transport roller is immersed in the adhesive resin tank while rotating, the adhesive resin transport roller is rotated by filling the resin filling portion communicating with the opening of the guide roller on the side of the adhesive resin transport roller. Even it can be retained. Since the resin coating hole communicates with the resin filling portion, the adhesive resin can be reliably supplied to the resin coating hole even if the adhesive resin transport roller is rotated at a high speed. Therefore, it becomes possible to manufacture the optical fiber ribbon at a high linear velocity, and the manufacturing cost can be reduced.
In addition, since the position of the optical fiber core wire is fixed by the adhesive resin transport roller, a precise mechanism for increasing the positioning accuracy is not necessary. Further, since the adhesive resin is only supplied by immersing it in an uncured adhesive resin while rotating the adhesive resin transport roller, there is no need for a mechanism for intermittently supplying the adhesive resin.

(6) In the optical fiber ribbon manufacturing apparatus according to (5), a drive unit that rotates the adhesive resin transport roller is provided.
Since the adhesive resin transport roller is driven by the drive unit, the intermittent connection pitch can be arbitrarily changed without changing the diameter of the roller.

(7) In the optical fiber ribbon manufacturing apparatus according to (6), a sensor that is disposed on the upstream side of the pass line with respect to the adhesive resin transport roller and detects a traveling speed of the optical fiber;
A control unit that controls the drive unit using information on the traveling speed detected by the sensor.
The traveling speed of the optical fiber core wire can be detected by the sensor, and the rotation speed of the adhesive resin transport roller can be controlled by the control unit based on the traveling speed information. Thereby, even if the running speed of the optical fiber core wire fluctuates, a desired intermittent connection pitch can be stably realized.

(8) In the manufacturing apparatus of the optical fiber ribbon of (5), the adhesive resin transport roller is installed so as to rotate by friction with the optical fiber.
Since the adhesive resin transport roller is installed so as to rotate due to friction with the optical fiber core, slip between the roller and the optical fiber core is minimized, and damage to the surface of the tape core can be suppressed. Further, even if the traveling speed of the optical fiber core wire changes, the rotational speed of the adhesive resin transport roller also changes accordingly, so that the intermittent connection pitch is stabilized. In addition, since an apparatus for driving the adhesive resin transport roller is not required, a more inexpensive apparatus configuration is possible.

  The downstream side alignment correction roller 10 keeps the parallel alignment until the optical fiber core wires 21 to 24, to which the adhesive resin is applied between the lines, are sent to the adhesive resin curing device 11 by the adhesive resin transport roller 7. So that it can be corrected.

The adhesive resin curing device 11 is a device for curing the adhesive resin 8a (for example, when the adhesive resin 8a is an ultraviolet curable resin, it is an ultraviolet irradiation device or the like).
The winding bobbin 12 is a bobbin for winding the manufactured intermittently connected optical fiber ribbon 20.

  Next, details of the configuration of the adhesive resin transport roller 7 and how to apply the adhesive resin will be described in detail with reference to the drawings. FIG. 2 is a configuration diagram of the adhesive resin transport roller 7 and the adhesive resin tank 8.

  As shown in FIGS. 1 and 2, a part of the adhesive resin transport roller 7 is immersed in an uncured adhesive resin 8 a (for example, a liquid ultraviolet curable resin) stored in the adhesive resin tank 8. It is installed so that.

  As shown to (a) of FIG. 2 and (b) which is the GG sectional drawing, the adhesive resin conveyance roller 7 includes a disk-shaped fiber roller 72 (72a to 72d) and a disk-shaped partition plate 73 ( 73a to 73c) are alternately stacked.

  The adhesive resin transport roller 7 is driven by the drive unit 5 so as to rotate in the direction indicated by the arrow H in FIG. That is, a part of the adhesive resin transport roller 7 is immersed in the adhesive resin 8a of the adhesive resin tank 8 from the right side in FIG.

  Further, on the upper left side of the adhesive resin tank 8, when the adhesive resin transport roller 7 goes out of the adhesive resin tank 8, the adhesive resin 8a is pressed against the peripheral edge of the fiber roller 72 (72a to 72d). A resin removing member 9 (for example, a spatula-like member) to be removed is provided.

Furthermore, the structure of the partition plate 73 and the structure of each partition plate 73a-73c are demonstrated. FIG. 3 is a diagram illustrating the structure of the partition plate and the configuration of each partition plate.
For example, as shown in FIG. 3, the partition plate 73 (73 a to 73 c) is divided into a plurality of regions (for example, regions A to F) in the circumferential direction, and resin coating holes are formed in a part of the regions. 74 (74A, 74E, 74C) is provided at least one (four in the example of FIG. 3). The resin coating holes 74 (74A, 74E, 74C) are connected to the openings 76 (76A, 76E, 76C) by flow paths 75 (75A, 75E, 75C), respectively.

  For example, as an example of the size of the partition plate 73 (73a to 73c), the diameter is 32.0 mm and the thickness is 0.2 mm, and the diameter of the resin coating hole 74 (74A, 74E, 74C) is 0.5 mm. is there. In this case, the circumference of the partition plate is about 100 mm.

  In the example of FIG. 3, the resin coating holes 74A, 74E, 74C and the openings 76A, 76E, 76C are respectively provided in the region A of the partition plate 73a, the region E of the partition plate 73b, and the region C of the partition plate 73c. Yes. 4A and 4B, which will be described later, the openings 76A, 76E, and 76C are openings 77A, 77E, and 77C of the fiber rollers 72a to 72d and openings 78A, 78E, and 78C of the guide rollers 71a and 71b, respectively. To communicate with each other.

The intermittent connection pitch of the optical fiber ribbons to be manufactured (the sum of the lengths of the connected portions of the two adjacent optical fiber cores and the lengths of the unconnected portions) is: It becomes equal to the circumferential length of the partition plate.
Further, the length of the connecting portion and the length of the non-connecting portion between the two adjacent optical fiber cores (for example, between the optical fiber core wires 21 and 22, respectively, the length of the portion A in FIG. The sum of the lengths of E, F and F) is the region where the resin coating hole 74 is provided (for example, angle θ1 = 72 °) and the region where the resin coating hole 74 is not provided (360 ° −θ1). = 288 °) in the circumferential direction. For example, as described above, when the circumference of the partition plate is about 100 mm and the angle θ1 = 72 °, the connecting portion length (the length of the region A) is 20 mm, and the non-connecting portion length (the regions B, C, and D). , E, F length) is 80 mm.

  Next, a manufacturing method for manufacturing an intermittently connected optical fiber tape 20 that is intermittently connected in a desired shape using the optical fiber tape core manufacturing apparatus 1 of the present embodiment will be described. 4A and 4B are views for explaining the application of the adhesive resin 8a by the rotation of the adhesive resin transport roller 7. FIG.

  As shown in FIG. 1, the plurality of optical fiber core wires 21 to 24 are arranged in parallel by the upstream side alignment correction roller 6 and sent to the adhesive resin transport roller 7. In adhesive resin conveyance roller 7, as shown in Drawing 4A and Drawing 4B, area A of partition board 73 (73a-73c) is formed between each line of optical fiber core wires 21-24 with rotation of adhesion resin conveyance roller 7. To F are inserted in order.

  While the adhesive resin transport roller 7 is in the adhesive resin tank 8 filled with the adhesive resin 8a, the resin filling portion 79 (79A, 79A, 79C, 79E) is filled with the adhesive resin 8a. The resin application holes 74 (74A, 74C, 74E) provided in the partition plates 73 (73a to 73c) are also filled with the adhesive resin 8a.

  And the peripheral part of each fiber roller 72 (72a-72d), when the adhesive resin conveyance roller 7 goes out of the adhesive resin tank 8, the resin removal member 9 is pressed and the adhesive resin 8a is removed. However, the resin filling portion 79 (79A, 79C, 79E) and the resin coating hole 74 (74A, 74C, 74E) are in a state filled with the adhesive resin 8a.

  In the region A, the resin coating hole 74A is provided only in the partition plate 73a sandwiched between the optical fiber core wires 21 and 22. Since the resin application hole 74A is connected to the resin filling part 79A via the flow path 75A, the adhesive resin 8a is further supplied from the resin filling part 79A to the resin application hole 74A. In the region A, the adhesive resin 8 a is discharged from the resin application hole 74 A between the optical fiber cores 21 and 22 and applied between the optical fiber cores 21 and 22.

  In the region B, since the resin coating holes 74 do not exist in the partition plates 73a to 73c, the adhesive resin 8a is not applied to each optical fiber core wire.

  Since the resin application hole 74C is connected to the resin filling part 79C via the flow path 75C, the adhesive resin 8a is further supplied from the resin filling part 79C to the resin application hole 74C. In the region C, the adhesive resin 8 a is discharged between the optical fiber cores 23 and 24 through the resin application hole 74 </ b> C and applied between the optical fiber cores 23 and 24.

  In the region D, since the resin coating hole 74 does not exist in the partition plates 73a to 73c, the adhesive resin 8a is not applied to each optical fiber core wire.

  Since the resin application hole 74E is connected to the resin filling part 79E via the flow path 75E, the adhesive resin 8a is further supplied from the resin filling part 79E to the resin application hole 74E. In the region E, the adhesive resin 8 a is discharged from the resin application hole 74 E between the optical fiber cores 22 and 23 and applied between the optical fiber cores 22 and 23.

  In the region F, since the resin coating holes 74 do not exist in the partition plates 73a to 73c, the adhesive resin 8a is not applied to each optical fiber core wire.

  When the adhesive resin transport roller 7 makes one rotation, the application of the adhesive resin 8a in the areas A to F is performed again, and the process is repeated thereafter.

  The optical fiber cores 21 to 24 to which the adhesive resin 8a is applied by the adhesive resin transport roller 7 are in a state in which the adhesive resin is intermittently applied at a desired interval between the lines as shown in FIGS. , And sent to the downstream side alignment correction roller 10.

  By passing through the downstream side alignment correction roller 10, the optical fiber core wires 21 to 24 are corrected to a parallel alignment and sent to the adhesive resin curing device 11.

  The optical fiber cores 21 to 24 corrected to the parallel arrangement are cured by the adhesive resin curing device 11 with the applied adhesive resin 8a (for example, when the adhesive resin 8a is an ultraviolet curable resin, an optical fiber is used. The adhesive resin 8a is cured by irradiating the core wires 21 to 24 with ultraviolet rays from the adhesive resin curing device 11).

  The optical fiber cores 21 to 24 having the adhesive resin 8a cured by the adhesive resin curing device 11 are wound as an intermittently connected optical fiber tape core 20 intermittently connected in a desired shape as shown in FIG. It is wound around the take-up bobbin 12.

  As described above, according to the manufacturing apparatus 1 and the manufacturing method of the optical fiber ribbon according to the embodiment described in detail, the traveling optical fibers 21 to 24 are brought into contact with the partition plate 73 and the fiber roller 72. Since the adhesive resin 8 a is removed from the peripheral portion of the roller 72 by the resin removing member 9, the adhesive resin 8 a is not applied to the contact surfaces of the optical fiber core wires 21 to 24 with respect to the fiber roller 72.

  However, the adhesive resin 8 a is applied to the side surfaces of the optical fiber core wires 21 to 24 adjacent to the partition plate 73 at the portion where the resin application hole 74 of the partition plate 73 is provided. Therefore, the adhesive resin 8a is intermittently provided between the optical fiber cores by bringing the part provided with the resin coating hole 74 and the part not provided with the partition plate 73 into contact with the optical fiber cores 21 to 24. Can be applied.

  When the adhesive resin conveyance roller 7 is immersed in the adhesive resin tank 8 while being rotated, the resin application hole 74 provided in the partition plate 73 is filled with the adhesive resin 8 a and the side surface of the adhesive resin conveyance roller 7. The adhesive resin 8a is filled in the resin filling portion 79 that is open to the surface, and can be held even if the adhesive resin transport roller 7 rotates. Since the resin application hole 74 communicates with the resin filling portion 79, the adhesive resin 8a can be reliably supplied to the resin application hole 74 even when the adhesive resin transport roller 7 is rotated at a high speed. Therefore, the intermittently connected optical fiber ribbon 20 that is intermittently connected to a desired shape can be manufactured by running the optical fibers 21 to 24 at a high speed, thereby reducing the manufacturing time and reducing the manufacturing cost. Can be reduced.

  Further, since the positions of the optical fiber core wires 21 to 24 are fixed by the adhesive resin transport roller 7, a precise mechanism for increasing the positioning accuracy is not necessary. Further, since the adhesive resin 8a is only supplied by immersing it in the uncured adhesive resin 8a stored in the adhesive resin tank 8 while rotating the adhesive resin transport roller 7, a mechanism for supplying the adhesive resin 8a intermittently Is not necessary.

  As described above, according to the present embodiment, an intermittently connected optical fiber tape core in which the optical fiber cores 21 to 24 are driven at high speed and intermittently connected to a desired shape without increasing the manufacturing cost. Wire 20 can be manufactured.

  In addition, since the drive unit 5 for rotating the adhesive resin transport roller 7 is provided and the adhesive resin transport roller 7 is driven by power, the intermittent connection pitch of the optical fiber ribbon 20 can be set without changing the diameter of the roller. It can be changed arbitrarily.

  Further, a sensor 3 for detecting the traveling speed of the optical fiber cores 21 to 24 is arranged on the upstream side of the pass line P with respect to the adhesive resin transport roller 7, and the information on the traveling speed detected by the sensor 3 is used for bonding. The rotational speed of the resin transport roller 7 may be controlled. In this case, the desired intermittent connection pitch of the optical fiber ribbon 20 is stably realized even if the traveling speed of the optical fibers 21 to 24 fluctuates. it can.

The adhesive resin transport roller 7 may be installed so as to be rotated by friction with the plurality of optical fiber cores 21 to 24 without being driven by the drive unit 5.
In this case, since the adhesive resin transport roller 7 is not driven by power and is rotated by friction with the plurality of optical fiber cores 21 to 24, the slip between the roller and the optical fiber core wire is minimized, and the optical fiber core wire The surface is prevented from being damaged. Further, even if the traveling speed of the optical fiber cores 21 to 24 is changed, the rotational speed of the adhesive resin transport roller 7 is also changed, so that the intermittent connection pitch is stabilized.

  In the above-described embodiment, the plurality of optical fiber core wires has four optical fibers, but may be other than four as long as there are a plurality of optical fibers. The configuration is adapted to the number of optical fiber cores (the number of fiber rollers 72 and partition plates 73 is adjusted). Moreover, although the partition plate 73 was divided | segmented into the area | region of AF, the number of area | regions and the method of division | segmentation may be other than this.
