Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing an optical fiber strand, and in particular, an optical fiber element that can easily separate a curable adhesive resin that bonds adjacent optical fiber strands together with an optical fiber strand. The present invention relates to a method for manufacturing a wire tape core and an apparatus for manufacturing an optical fiber core tape.

  2. Description of the Related Art Conventionally, an optical fiber ribbon fiber is formed by applying a plurality of UV resins in parallel to the entire circumference of a single optical fiber. In order to separate the optical fiber strand tape core formed in this way, it is necessary to remove the UV resin adhering to the entire circumference of the single optical fiber strand. However, when removing the UV resin, excessive force such as twisting, bending, and lateral pressure is applied to the optical fiber, which may deteriorate the optical fiber and take time for the separation work itself. There was a problem that it was.

  As shown in FIG. 7A, an optical fiber strand 101 that solves this problem is manufactured by thinning a tape forming material 105 that connects optical fiber strands 103 to each other. Has been. As shown in FIG. 7 (B) and FIG. 7 (C), this optical fiber strand tape core wire 101 can be separated into a single core by easily stripping the thin tape material 105 with a tool (not shown). It can be done easily.

  In addition, referring to FIG. 8, as another optical fiber ribbon core wire 107, the connecting portion 109 and the separating portion are connected by intermittently connecting adjacent optical fiber strands 103 with a connecting resin. An intermittently fixed tape core wire 111 is manufactured. Since this optical fiber strand tape core wire 107 has a cut (separation part 111) between the optical fiber strands 103, the separation tool 113 is inserted into the separation part 111 using the cut. By sliding, the separation part 111 can be expanded and single core separation can be easily performed.

  Moreover, in patent document 1, it is taped without applying UV resin to the perimeter of an optical fiber strand by using the method of a dispenser form, and the optical fiber strand tape core wire which is thin and easy to separate is made. A manufacturing method is described. That is, the energy beam curable resin is discharged from a cylindrical nozzle having a thin tip onto at least one arrangement plane side of the plurality of optical fiber strands arranged in a row in close contact while running the plurality of optical fiber strands. Thereafter, the energy ray curable resin is cured, and the plurality of optical fiber strands are bonded and integrated.

  By the way, in the conventional optical fiber strand tape core wire, for example, the optical fiber strand tape core wire 101 in which the tape material 105 is thin has the following problems when the tape material 105 is peeled off. That is, (1) it takes a single core separation work time until the taped material 105 is peeled off. (2) In order to peel off the taped material 105, a complicated tool such as a flexible fiber or a file is required. (3) Since a force such as bending is easily applied to the optical fiber 103 at the time of single-core separation, the loss fluctuation at the time of division is large.

  Further, the intermittently fixed tape core wire 107 has a problem in that a notch (separation part 111) that has entered in advance may be caught during wiring work and cause problems such as disconnection. Therefore, care must be taken in handling, which has been a factor in reducing the efficiency of wiring work.

  Further, in Patent Document 1, in order to fabricate a tape core wire that can be split into a single core, a UV curable resin is applied between the optical fiber strands to connect the optical fiber strands. Since the curable resin is a liquid, it spreads on the optical fiber after a while, so that the bonding area between the UV curable resin and the optical fiber becomes wide. In other words, the UV curable resin spreads until the contact angle between the optical fiber and the UV curable resin becomes a constant value.

  Immediately after application of the resin, if cured immediately, a tape core having a small bonding area between the taped material and the optical fiber can be formed, so that the strength as the tape core is insufficient and handling becomes difficult. On the other hand, if the UV curable resin is cured with the adhesive area widened, the adhesive area between the taped material and the optical fiber strand becomes wider, and the resin for bonding the optical fiber strands comes into contact with each other and splits. An inferior tape core wire is produced. However, there is a problem in that the cross-sectional shape of the UV curable resin after ejection cannot be set to a target shape.

  According to the present invention, an optical fiber strand tape core having a structure that can be easily separated without losing time by preventing the resins for bonding the optical fiber strands from contacting each other. An object of the present invention is to provide a method for manufacturing a wire and an apparatus for manufacturing an optical fiber ribbon tape.

In order to solve the above-described problems, a method of manufacturing an optical fiber strand tape according to the present invention includes a curing type in which two or more optical fiber strands are used as a taped material in at least one array plane side row. A method of manufacturing a long optical fiber ribbon core integrated into a tape shape with an adhesive resin, the step of concentrating a plurality of optical fiber strands, and the optical fiber strands adjacent to each other A step of dropping a curable adhesive resin that connects adjacent optical fiber strands on at least one of the arrangement plane sides, a step of measuring an adhesive width and an adhesive thickness of the curable adhesive resin, and a measured curable mold Based on the bonding width and bonding thickness of the adhesive resin , the curable adhesive resin that bonds adjacent optical fiber strands and the curable adhesive resin that bonds other adjacent optical fiber strands do not adhere, And adjacent optical fiber When a state having a protrusion height than the tangent to the circumference popping outside, curing adhesive resin moved the resin curing irradiation apparatus to properly cure allowed to position, irradiating the resin cured from resin curing irradiator it is characterized in that comprises a step of curing the irradiated curing adhesive resin lines.

  Further, in the method for manufacturing an optical fiber strand tape according to the present invention, the curable adhesive resin may be continuously formed in the length direction of the optical fiber in the optical fiber strand tape manufacturing method. preferable.

An apparatus for manufacturing an optical fiber strand of the present invention has a plurality of optical fiber strands in close contact with each other and arranged in a row, and is applied in a tape form by applying a curable adhesive resin as a tape forming material. An apparatus for manufacturing a long optical fiber strand to be converted into an optical fiber, and a concentrator for concentrating a plurality of optical fiber strands, and an array of at least one of adjacent optical fiber strands concentrated in the concentrator Adhesive resin coating device having a discharge nozzle for dropping a curable adhesive resin for connecting optical fiber strands adjacent to each other on a flat surface side, a resin curing irradiation device for curing the dropped curable adhesive resin, and a resin curing device Based on the adhesive width and thickness of the curable adhesive resin measured by the adhesive resin contour measuring device and the adhesive resin contour measuring device that measures the adhesive width and thickness of the curable adhesive resin cured by the irradiation device And curing adhesive resin for bonding the adjacent optical fiber to each other, without curing adhesive resin for bonding the optical fiber adjacent the other adhesive, and tangent to the outer periphery of the optical fiber adjacent more when the state that have a protrusion height popping outside, that a control device for controlling a command unit which gives an instruction for moving the curing adhesive resin illumination properly cured resin to cure allowed to position device It is characterized by.

  As can be understood from the means for solving the above problems, according to the method for manufacturing an optical fiber ribbon of the present invention, a curable adhesive resin is applied (dropped) between optical fibers. After that, the curable adhesive resin is not adjacent to the taped resin for adhering adjacent optical fiber strands, and the taped resin for adhering the adjacent optical fiber strands is adjacent. By irradiating a resin curing irradiation line and curing the surface of the curable adhesive resin when the protrusion has a protruding height that protrudes outward from the tangent line that touches the outer periphery of the two optical fiber strands, It is possible to arbitrarily adjust the bonding area and shape of the curable adhesive resin that becomes the fiber strand and the taped material. Therefore, the optical fiber strand manufactured can easily separate the optical fiber from the curable adhesive resin without taking any time without deformation of the optical fiber. Moreover, since the bonding area between the optical fiber and the taped material is appropriate, the optical fiber can be divided without applying excessive force, so that the division loss is low and the time required for the division work is short. It will be a thing.

  Moreover, according to the optical fiber ribbon optical fiber manufacturing apparatus of the present invention, the adhesive width and adhesive thickness of the curable adhesive resin applied and cured between the optical fiber elements are measured by the adhesive resin outline measuring device. Based on this measurement data, the taped resin for adhering adjacent optical fiber strands and the taped resin for adhering adjacent optical fiber strands to each other are not bonded, and 2 adjacent When the protrusion has a protruding height that protrudes outward from the tangent line that touches the outer periphery of the two optical fiber strands, the surface of the curable adhesive resin can be cured by irradiating the resin curing irradiation beam. Therefore, the optical fiber strand manufactured can easily separate the optical fiber from the curable adhesive resin without taking any time without deformation of the optical fiber. Moreover, since the bonding area between the optical fiber and the taped material is appropriate, the optical fiber can be divided without applying excessive force, so that the division loss is low and the time required for the division work is short. It will be a thing.

  Embodiments of the present invention will be described below with reference to the drawings.

  Referring to FIG. 1, an optical fiber strand tape manufacturing apparatus 1 according to this embodiment is arranged (in parallel) in a row in close contact with, for example, four optical fiber strands 3 while running. An apparatus that manufactures an optical fiber strand 7 (hereinafter simply referred to as “tape core”) by applying, for example, a UV curable resin 5 as a curable adhesive resin to be a taped material, and integrating it into a tape shape. is there.

  In this embodiment, the tape core wire 7 has a configuration in which, for example, four optical fiber strands 3 having a diameter of 250 μm are integrated in parallel.

  More specifically, the manufacturing apparatus 1 for an optical fiber strand tape core wire moves, for example, to the concentration guide roller 11 while running, for example, four optical fiber strands 3 fed from four optical fiber strand delivery bobbins 9. And a concentrator 13 for concentrating the plurality of optical fiber strands 3 so as to be closely arranged in a line. The concentrator 13 is composed of a flat plate concentrator 15 having a plurality of guide grooves (not shown) that guide the four optical fiber strands 3. However, it is not limited to the concentrating guide 15 but may be a concentrating guide roller having a plurality of guide grooves.

  Further, above the concentrator 13, an adhesive resin application for applying, for example, a UV curable resin 5 as a curable adhesive resin for connecting the adjacent optical fiber strands 3 collected by the concentrator guide 15. A device 17 is provided. The adhesive resin coating device 17 has a discharge nozzle 19 for dropping and applying the UV curable resin 5 between the adjacent optical fiber strands 3. In FIG. 1, one discharge nozzle 19 is disposed above the two optical fiber strands 3. The discharge nozzle 19 communicates with a resin supply control device 21 that controls the discharge of the UV curable resin 5 via a resin supply pipe 23. Further, the resin supply control device 21 is connected to a control device 25 that controls the entire manufacturing apparatus 1.

  As another embodiment, in the case of a four-core tape core wire 7 in which four optical fiber strands 3 are arranged in parallel, the three discharge nozzles 19 are located above the adjacent optical fiber strands 3. For example, FIG. 1 shows a configuration of a production line as viewed from the side, and the line advances from left to right with four optical fibers 3 arranged in parallel. The discharge nozzles 19 are arranged in a row in accordance with the parallel optical fibers 3. Further, in the case of an 8-fiber ribbon, seven discharge nozzles 19 are shown, for example, in FIG. 1 when the production line is viewed from the side, and the line has eight optical fibers 3 arranged in parallel. Proceeding from left to right. The discharge nozzles 19 are arranged in a row in accordance with the parallel optical fibers 3.

  In addition, if the plurality of fibers 3 to be coated with resin are in a state of being perpendicular to the ground, it is easy to apply the resin to the front and back surfaces of the tape core wire 7 as shown in FIG. Such an optical fiber strand tape core wire 7 is obtained. However, in the state where the four optical fibers 3 are traveling in parallel to the ground, it is necessary to apply resin from the lower surface of the tape core wire 7, but resin application is possible. Therefore, for example, in the case of the 4-fiber ribbon 7, the three discharge nozzles 19 can be alternately arranged above and below between the adjacent optical fiber wires 3. The discharge nozzle 19 below the optical fiber 3 is disposed at a position away from the concentrator 13, that is, on the front side in the traveling direction of the optical fiber 3.

The resin supply control device 21 controls various conditions such as the discharge amount, discharge speed, discharge position, discharge start and stop, and the time of the UV curable resin 5 discharged from each discharge nozzle 19. It is.

  Further, a curable adhesive resin applied between the adjacent optical fiber strands 3 by the adhesive resin coating device 17 on the front side in the running direction of the optical fiber strands 3 with respect to the concentrator 13. For example, a UV lamp 27 is provided as a resin curing irradiation device for curing the UV curable resin 5. The UV lamp 27 is configured to be movable and adjustable along the traveling direction of the optical fiber 3, and is connected to the control device 25, and various kinds of UV irradiation amount, UV irradiation start and stop, UV irradiation time, and the like. This is a configuration in which conditions are controlled.

  The curable adhesive resin is not limited to the UV curable resin 5 that is cured by UV irradiation of, for example, ultraviolet rays as the resin curing irradiation beam. For example, by irradiating a resin curing irradiation beam such as radiation or an electron beam. A curable resin or a thermosetting adhesive resin other than the UV curable resin 5 can be used.

  Further, an adhesive resin outer shape for measuring the adhesive width and adhesive thickness of the UV curable resin 5 cured by the UV irradiation by the UV lamp 27 on the front side in the running direction of the optical fiber 3 with respect to the UV lamp 27. A measuring device 29 is provided. In this embodiment, the adhesive resin profile measuring device 29 includes a first CCD camera 31 that measures the adhesive width in a plane from above the optical fiber 3 and a side view from the side of the optical fiber 3. And a second CCD camera 33 for measuring the adhesive thickness. The first and second CCD cameras 31 and 33 are connected to an image processing device 35 for processing the images captured by the first and second CCD cameras 31 and 33 so that the dimensions can be measured. The image processing device 35 is connected to the control device 25. Instead of the second CCD camera 33, a thickness meter that measures the thickness of the tape core wire may be used.

  Further, a capstan roller 39 is provided on the front side in the running direction of the optical fiber 3 with respect to the adhesive resin outline measuring device 29, and the optical fiber 3 is pulled through a guide roller 37, which is not shown. The tension is adjusted by the dancer roller and then wound around the winding drum 41. The capstan roller 39 is connected to the control device 25, and the traveling speed of the optical fiber 3 described above is adjusted by the rotation speed being controlled by the control device 25.

  Referring to FIG. 2, the control device 25 includes a CPU 43 as a central processing unit. The CPU 43 includes an input device 45 such as a keyboard and a touch panel for inputting various data and programs, a CRT, A display device 47 such as a liquid crystal and a memory 49 for storing a program input from the input device 45 and various detection data are provided.

  Further, the CPU 43 is adjacent to the CPU 43 based on the measurement data of the adhesive width and adhesive thickness of the UV curable resin 5 measured by the first and second CCD cameras 31 and 33 which are the adhesive resin outer shape measuring device 29 described above. What percentage of the circumferential length of the optical fiber strand 3 is bonded to the UV curable resin 5 in which the optical fiber strands 3 are bonded to each other in a plane perpendicular to the length direction of the optical fiber strand 3. The first arithmetic unit 51 for calculating the position and the position at which the vertex of the UV curable resin 5 is located with respect to the tangent line TL (see FIG. 3) in contact with the outer periphery of two adjacent optical fiber strands 3 are calculated. Two arithmetic units 53 are provided.

  Further, the CPU 43 has a protrusion height H (FIG. 3) where the UV curable resin 5 adheres with an adhesion length BL and protrudes outside the tangent line TL contacting the outer periphery of two adjacent optical fiber strands 3. And a comparison / determination device 55 that determines whether or not the UV curable resin 5 is in an appropriate state. The comparison / determination device 55 determines whether the UV curable resin 5 is in an appropriate state. A command unit 57 is provided to give a command to move the UV lamp 27 to a position to be cured.

  Based on the above configuration, the manufacturing method of the optical fiber strand tape according to the present embodiment will be described. Four optical fiber strands 3 are sent out from two optical fiber strand delivery bobbins 9, and are concentrated guides. The four optical fiber strands 3 are arranged in close contact with each other by being concentrated in the guide groove of the concentrating guide 15 of the concentrator 13 while traveling so as to gradually approach the roller 11. The traveling speed of the optical fiber 3 at this time is held at a constant linear speed by a capstan roller 39 controlled by the control device 25.

  In this way, two or more optical fiber strands 3 are collected by the concentrating guide 15, and UV curing discharged from the discharge nozzle 19 of the adhesive resin coating device 17 in a state where the optical fiber strands 3 are sufficiently close to each other. Resin 5 is dropped and applied between adjacent optical fiber strands 3. As a coating method, in addition to the dispenser capable of ejecting a small amount of the UV curable resin 5 as described above, a coating die or the like capable of ejecting the UV curable resin 5 aiming only between the optical fiber strands 3 is fisted. I can make it.

  Thereafter, the dropped UV curable resin 5 is cured by being irradiated with UV by the UV lamp 27. However, the shape of the UV curable resin 5 changes depending on the timing of UV irradiation.

  More specifically, immediately after the UV curable resin 5 is dropped and applied between the optical fiber strands 3, it remains in the form of droplets as shown in FIG. However, since the UV curable resin 5 is a liquid, a certain contact angle with the optical fiber 3 as shown in (b) to (c) of FIG. Until it reaches the surface of the optical fiber 3. As it spreads in this way, the bonding area between the UV curable resin 5 and the optical fiber 3 becomes wider. That is, the ratio (%) of the bonding length BL to the circumferential length of the optical fiber strand 3 on the surface perpendicular to the length direction of the optical fiber strand 3 increases, and the adjacent optical fiber strands 3 are bonded. Contact with resin.

  Therefore, as shown in FIG. 4A, when the resin is cured immediately after application of the resin, the ratio (%) of the bonding length BL to the circumferential length of the optical fiber 3 is reduced.

  On the other hand, as shown in FIG. 4C, when the UV curable resin 5 is cured in a state where the adhesion area is widened, the ratio (%) of the adhesion length BL to the circumferential length of the optical fiber 3 ) Increases and the resin comes into contact.

  The adhesion per unit area of the optical fiber 3 and the taped material 5 varies depending on the type and combination of the optical fiber 3 and the taped material 5. It is necessary to change the bonding length BL depending on the strength of the adhesion per unit area. This is because in the type and combination of the optical fiber 3 and the taped material 5 having weak adhesion, the strength as the tape core 7 is insufficient unless the adhesion length BL is increased.

  The appropriate bonding length BL differs depending on the types of the optical fiber 3 and the taped material 5, and therefore it is necessary to adjust the bonding length BL to be appropriate. Further, when the bonding length BL becomes long, it comes into contact with a taped resin for bonding the adjacent optical fiber strands 3 together.

  The reason why the taped resins are not in contact with each other is that when the taped resin is removed from the optical fiber 3 and separated into single fibers, the taped resin is bonded to a wide area across two or more optical fiber strands 3. This is because removal takes time and effort.

  The reason why the protrusion height H is necessary is that there is no taped resin immediately above the optical fiber 3, so when the optical fiber 3 is laminated or the optical fiber 3 is mounted on the cable with high density. In such a case, there is a possibility that a lateral pressure is directly applied to the optical fiber 3 or that direct damage to the optical fiber 3 occurs. Therefore, it is necessary to provide a protrusion made of taped resin.

  In this embodiment, as shown in FIG. 4 (b), two adjacent lights are bonded with BL having a bonding length between (a) and (c). A state having a protruding height that protrudes outward from the tangent line TL in contact with the outer periphery of the fiber strand 3 is regarded as an appropriate state. In this proper state, the tape core wire 7 having good splitting property (separability) and appropriate strength is produced.

  Therefore, it is necessary to adjust the movement of the UV lamp 27 to a position where the UV curable resin 5 is cured in an appropriate state as shown in FIG. In this embodiment, the UV curable resin 5 cured by UV irradiation is imaged by the first and second CCD cameras 31 and 33 of the adhesive resin contour measuring device 29 for the adhesive width and adhesive thickness, and the image processing device 35 takes the image. It is processed. Further, based on the image processing data, the first calculation device 51 of the control device 25 calculates the percentage of the circumference of the optical fiber 3 by which the adhesion length BL of the UV curable resin 5 is calculated, and the second calculation. The position of the UV curable resin 5 is calculated by the device 53 with respect to the tangent line TL in contact with the outer circumferences of the two adjacent optical fiber strands 3.

  Next, the comparison / determination device 55 of the control device 25 determines whether or not the UV curable resin 5 cured by the UV lamp 27 is in the proper state. Based on this determination, the command unit 57 of the control device 25 gives a command to move the UV lamp 27 to a position where the UV curable resin 5 is properly cured. In addition, in the instruction | indication part 57, adhesive resin coating device is controlled so that various conditions, such as the position of the discharge nozzle 19, the discharge amount of UV curable resin 5, discharge speed, discharge position, the start and stop of discharge, and the time, may be controlled. A command is given to the resin supply control device 21 and the discharge nozzle 19.

  As described above, the cured state of the UV curable resin 5 dropped between the adjacent optical fiber strands 3 can be controlled. That is, after the UV curable resin 5 is dropped (applied) between the optical fiber strands 3, UV irradiation is performed when the UV curable resin 5 spreads to the target area on the surface of the optical fiber strand 3. By using the method of curing the surface of 5, it is possible to arbitrarily adjust the bonding area between the optical fiber 3 and the UV curable resin 5 as a tape forming material.

  The time required for the UV curable resin 5 to spread to the target adhesion area is determined by the viscosity of the UV curable resin 5 and the like. However, in this embodiment, by adjusting the irradiation position of the UV lamp 27 to reflect the result of measuring the cured state as described above, the temporal element for spreading the UV curable resin 5 to the target adhesion area is as follows. Will be included.

  Further, the UV irradiation amount necessary for fixing the shape of the UV curable resin 5 is determined by the ease of curing of the used UV curable resin 5. In order to fix the shape of the UV curable resin, it is sufficient that at least the surface of the applied UV curable resin 5 is hardened. Further, in order to cure the entire applied UV curable resin 5, the main UV irradiation for the entire curing may be performed after curing only the surface.

  Next, the reason for the appropriate state of the shape of the UV curable resin 5 described above will be described.

Using the above-described optical fiber strand tape core manufacturing apparatus 1, various multi-core tape core wires 7 were manufactured under different conditions. That is, the UV curable resin 5 was dropped between the optical fiber strands 3 while moving the optical fiber strands 3 of a plurality of cores at an arbitrary speed to obtain a multi-fiber ribbon core wire 7. As the conditions, the viscosity of the UV curable resin 5 is 5.8 to 8.0 Pa · s, the UV illuminance is 180 mW / cm ² , and the coating amount of the UV curable resin 5 is about 7.5 mm ³ / sec. . The diameter of the optical fiber 3 is, for example, 250 μm. It was expressed by the relationship between the time until UV irradiation when manufacturing each of the multi-core ribbons 7, the bonding area of the optical fiber 3 and the taped material 5. Moreover, the division | segmentation experiment of each multi-core tape core wire 7 was conducted. The results are as shown in Table 1.

  As can be seen from Table 1, a UV curable resin 5 (tape material) is applied to an adhesion length BL (area) of 20 to 30% with respect to the circumferential length (surface area) of one optical fiber 3. When cured, it was possible to obtain a tape core wire 7 having a strength suitable for handling as a tape core wire and good splitting property of the optical fiber 3. However, if it is about 30%, deformation of the fiber after splitting is seen, and when the bonding length BL is 40% or more, the taped resin is in contact with each other, so the degree of adhesion between the optical fiber strand 3 and the taped material is Since it is too large, it is difficult to divide the optical fiber 3. That is, when the tape core wire 7 is divided into single cores by applying a twisting, bending, lateral pressure or the like to the tape core wire 7, the smaller the bonding area between the taped material 5 and the optical fiber 3 is UV curing. Removal of the optical fiber 3 from the resin 5 is facilitated.

  As another example of the optical fiber strand tape 7 obtained by the manufacturing method of the optical fiber strand tape of this embodiment, an optical fiber strand tape as shown in FIG. 5 is obtained. It is also possible.

  The basic configuration of the tape core 7 of this embodiment is the same as that of the above-described two-core ribbon 7 even if the number of the tape cores is two, four, eight or more. is there. Although FIG. 6 shows the 8-core tape core wire 7, the UV curable resin 5 as the tape forming material can be a continuously formed tape core wire 7 as shown in FIG. This point applies to all the tape core wires 7 regardless of the number of the optical fiber strands 3.
