Description

本発明は、複数の光ファイバをテープ樹脂によってテープ形状に保持した光ファイバテープ及びその単心分離方法に関するものである。   The present invention relates to an optical fiber tape in which a plurality of optical fibers are held in a tape shape with a tape resin, and a single-fiber separation method thereof.

図３は従来の光ファイバテープの一例を示す断面図である。図３に示すように、４本の光ファイバ１１を接触させて並行に配置した周囲にテープ樹脂１２を被覆するように設けてテープ形状に保持して構成される。   FIG. 3 is a cross-sectional view showing an example of a conventional optical fiber tape. As shown in FIG. 3, four optical fibers 11 are arranged in contact with each other and are provided so as to cover the tape resin 12 and are held in a tape shape.

図９は図３の光ファイバテープの単心分離方法を示す構成説明図である。図９において、１３は分離位置である。   FIG. 9 is an explanatory diagram showing the structure of the single-fiber separation method for the optical fiber tape of FIG. In FIG. 9, 13 is a separation position.

図９に示すように、光ファイバテープの単心分離は、光ファイバテープを長手方向に直線状に保持し、保持した光ファイバテープ内の光ファイバ１１と光ファイバ１１の中間の分離位置１３に鋭利な刃を挿入し、鋭利な刃を光ファイバ１１の長手方向と平行になるようスライド移動させることにより、必要な長さ分を単心に分離する。   As shown in FIG. 9, the single-fiber separation of the optical fiber tape is performed by holding the optical fiber tape in a straight line in the longitudinal direction and at the separation position 13 between the optical fiber 11 and the optical fiber 11 in the held optical fiber tape. By inserting a sharp blade and sliding the sharp blade so as to be parallel to the longitudinal direction of the optical fiber 11, a necessary length is separated into a single core.

図４は従来考えられている光ファイバテープを示す断面図である。図４において、１４は光ファイバ、１５はテープ樹脂である。図４に示すように、４本の光ファイバ１４を接触させて並行に配置した周囲にテープ樹脂１５を極力薄く被覆するように設けてテープ形状に保持して構成される。図４の光ファイバテープを単心分離する場合には、光ファイバテープを長手方向に直線状に保持し、テープ樹脂１５を硬いブラシで擦って剥離して光ファイバ１４を分離している。   FIG. 4 is a cross-sectional view showing a conventionally considered optical fiber tape. In FIG. 4, 14 is an optical fiber, and 15 is a tape resin. As shown in FIG. 4, a tape resin 15 is provided as thinly as possible around the four optical fibers 14 in contact with each other and arranged in parallel, and is held in a tape shape. When the optical fiber tape shown in FIG. 4 is separated into single fibers, the optical fiber 14 is separated by holding the optical fiber tape linearly in the longitudinal direction and peeling the tape resin 15 with a hard brush.

図３及び図４の光ファイバテープの単心分離は、光ファイバテープを長手方向に保持するため、分離する距離に合わせた長さの保持具が必要になり、保持具が分離距離に合わせた大きな構造となるため、作業スペースの確保も必要であった。   In the single-fiber separation of the optical fiber tape shown in FIGS. 3 and 4, in order to hold the optical fiber tape in the longitudinal direction, a holder having a length corresponding to the distance to be separated is required, and the holder is adjusted to the separation distance. Because of the large structure, it was necessary to secure a work space.

また、分離用の鋭利な刃により繰り返し分離を実施するため、鋭利な刃の劣化や作業不慣れ等による分離の失敗により、分離する光ファイバテープ内の光ファイバに通信障害を発生することが課題となっている。   Further, since separation is repeatedly performed with a sharp blade for separation, it is a problem that a communication failure occurs in the optical fiber in the optical fiber tape to be separated due to failure of separation due to deterioration of the sharp blade or unfamiliar work. It has become.

特許文献１には、光ファイバテープを単心の光ファイバに分離する工具が開示されている。この工具を用いた場合、［１］複数の分割刃への対応、及び［２］分離する長手方向の作業スペースが必要となる。   Patent Document 1 discloses a tool for separating an optical fiber tape into a single optical fiber. When this tool is used, [1] correspondence to a plurality of divided blades and [2] a work space in the longitudinal direction for separation are required.

本発明は上記の事情に鑑みてなされたもので、光ファイバテープのテープ形状の保持と分離の容易さとを両立でき、且つ分離する距離に合わせた長さの保持具を不要として作業スペースを少なくし、鋭利な刃を使用しないことにより通信障害を回避する光ファイバテープ及びその単心分離方法を提供することを目的とする。   The present invention has been made in view of the above circumstances, and can maintain both the tape shape of the optical fiber tape and the ease of separation, and does not require a holder having a length corresponding to the distance to be separated, thereby reducing the work space. In addition, an object of the present invention is to provide an optical fiber tape that avoids communication failure by not using a sharp blade and a single-fiber separation method thereof.

上記目的を達成するために本発明は、複数の光ファイバをテープ樹脂によってテープ形状に保持した光ファイバテープにおいて、テープ樹脂を光ファイバと光ファイバの隣接部近傍に、隣接部が最も高く突出するように配設することを特徴とする光ファイバテープ。   In order to achieve the above object, according to the present invention, in an optical fiber tape in which a plurality of optical fibers are held in a tape shape with a tape resin, the adjacent portion protrudes highest in the vicinity of the adjacent portion between the optical fiber and the optical fiber. An optical fiber tape characterized by being arranged as described above.

また本発明は、前記光ファイバテープにおいて、テープ樹脂が光ファイバと光ファイバの隣接部毎に光ファイバテープの一方の片面もしくは他方の片面に配設されることを特徴とするものである。   According to the present invention, in the optical fiber tape, the tape resin is disposed on one side or the other side of the optical fiber tape for each adjacent portion of the optical fiber.

また本発明は、前記光ファイバテープにおいて、テープ樹脂が光ファイバテープの両面に配設されることを特徴とするものである。   The present invention is also characterized in that in the optical fiber tape, a tape resin is disposed on both surfaces of the optical fiber tape.

また本発明の光ファイバテープの単心分離方法は、前記光ファイバテープに、前記光ファイバテープの光ファイバの直径とほぼ等しい厚さの介在部材を介在して分離工具で上下方向から応力を加えることにより、テープ樹脂を破壊すると共に光ファイバを分離することを特徴とする。   In the optical fiber tape single fiber separation method according to the present invention, stress is applied to the optical fiber tape from above and below with an isolation member having a thickness substantially equal to the diameter of the optical fiber of the optical fiber tape. Thus, the tape resin is broken and the optical fiber is separated.

また本発明の光ファイバテープの単心分離方法は、前記光ファイバテープを、分離工具に設けられたブラシで挟み込み、前記ブラシを光ファイバテープの長手方向にスライドさせることにより、光ファイバがテープ樹脂から剥離して分離することを特徴とする。   The optical fiber tape single-fiber separation method according to the present invention includes sandwiching the optical fiber tape with a brush provided in a separation tool, and sliding the brush in the longitudinal direction of the optical fiber tape so that the optical fiber is a tape resin. It is characterized by peeling from and separating.

本発明の光ファイバテープは、テープ樹脂を光ファイバと光ファイバの隣接部近傍に、隣接部が最も高く突出するように配設することにより、テープ樹脂の厚い部分とテープ樹脂の無い（薄い）部分の２種類を配置することで、テープ形状の保持及び分離の容易さを両立できる。   In the optical fiber tape of the present invention, the tape resin is disposed in the vicinity of the adjacent portion between the optical fiber and the optical fiber so that the adjacent portion protrudes highest, so that there is no thick portion of the tape resin and no tape resin (thin). By arranging the two types of portions, it is possible to achieve both tape shape retention and ease of separation.

また、本発明の光ファイバテープの単心分離方法は、光ファイバと光ファイバの隣接部に位置するテープ樹脂の最も高く突出した部分に応力を加える方法及び軟らかいブラシでテープ樹脂を剥がしとる方法としたことで、分離工具を安価とし、更に作業の簡素化・安全化を図ることができる。   The optical fiber tape single-fiber separation method of the present invention includes a method of applying stress to the highest protruding portion of the tape resin located in the adjacent portion of the optical fiber and the optical fiber, and a method of peeling the tape resin with a soft brush. As a result, the separation tool can be made inexpensive, and the work can be simplified and made safer.

また、本発明の光ファイバテープの単心分離方法は、テープ樹脂を押し潰す方法であるため、長手方向にスライドさせることがなく、長手方向への保持が不要となり、作業スペースも小さくなる。   In addition, since the optical fiber tape single fiber separation method of the present invention is a method of crushing the tape resin, it is not slid in the longitudinal direction, it is not necessary to hold it in the longitudinal direction, and the working space is reduced.

更に、本発明の光ファイバテープの単心分離方法は、テープ樹脂を押し潰す方法であるため、鋭利な刃も不要であり、刃の劣化による光ファイバの通信障害が発生しない。分離作業も、テープ樹脂を押し潰す単純な方法であるため、作業不慣れによる分離の失敗も削減される。   Furthermore, since the optical fiber tape single-fiber separation method of the present invention is a method of crushing the tape resin, a sharp blade is not necessary, and communication failure of the optical fiber due to the deterioration of the blade does not occur. Since the separation work is also a simple method of crushing the tape resin, the failure of separation due to unfamiliar work is reduced.

以下図面を参照して本発明の実施の形態を詳細に説明する。
図１は本発明の第１の実施形態に係る光ファイバテープを示す断面図である。図１において、２１は光ファイバ、２２はテープ樹脂である。図１に示すように、複数の光ファイバ２１はテープ樹脂２２によってテープ形状に保持される。前記テープ樹脂２２は光ファイバ２１と光ファイバ２１の隣接部近傍に、隣接部が最も高く突出するように中高に配設される。この場合、テープ樹脂２２は光ファイバと光ファイバの隣接部毎に光ファイバテープの一方の片面もしくは他方の片面を選択して片面のみに配設される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the plurality of optical fibers 21 are held in a tape shape by a tape resin 22. The tape resin 22 is disposed at a middle height in the vicinity of the optical fiber 21 and the adjacent portion of the optical fiber 21 so that the adjacent portion protrudes highest. In this case, the tape resin 22 is disposed only on one side of the optical fiber, with one side of the optical fiber tape or the other side selected for each adjacent portion of the optical fiber.

図２は本発明の第２の実施形態に係る光ファイバテープを示す断面図である。図２において、３１は光ファイバ、３２はテープ樹脂である。図２に示すように、複数の光ファイバ３１はテープ樹脂３２によってテープ形状に保持される。前記テープ樹脂３２は光ファイバ３１と光ファイバ３１の隣接部近傍に、隣接部が最も高く突出するように中高に配設される。前記テープ樹脂３２は光ファイバテープの両面にそれぞれ配設される。   FIG. 2 is a cross-sectional view showing an optical fiber tape according to a second embodiment of the present invention. In FIG. 2, 31 is an optical fiber, and 32 is a tape resin. As shown in FIG. 2, the plurality of optical fibers 31 are held in a tape shape by a tape resin 32. The tape resin 32 is disposed at a middle height in the vicinity of the optical fiber 31 and the adjacent portion of the optical fiber 31 so that the adjacent portion protrudes highest. The tape resin 32 is disposed on both sides of the optical fiber tape.

尚、テープ樹脂２２，３２の材質としては、通常の光ファイバテープに用いられているテープ樹脂を用いることができる。例えば、紫外線硬化型のテープ樹脂を用いればよい。このテープ樹脂は、適当な応力をかけることによって、光ファイバから剥離し、破断させることができる。   In addition, as a material of the tape resins 22 and 32, a tape resin used in a normal optical fiber tape can be used. For example, an ultraviolet curable tape resin may be used. The tape resin can be peeled off from the optical fiber and broken by applying an appropriate stress.

It is rubbish.

図５（ａ）に示すように、上面が平坦な下部分離工具２４上には図１に示す光ファイバテープが載置されると共に前記光ファイバテープの両側には光ファイバ２１の直径とほぼ等しい高さ（厚さ）の介在部材２５が設置される。   As shown in FIG. 5A, the optical fiber tape shown in FIG. 1 is placed on the lower separation tool 24 having a flat upper surface, and the diameter of the optical fiber 21 is substantially equal on both sides of the optical fiber tape. An interposition member 25 having a height (thickness) is installed.

その後、図５（ｂ）に示すように、下面が平坦な上部分離工具２３を前記光ファイバテープの上面より押圧することにより、前記光ファイバテープは介在部材２５を介在して上部分離工具２３と下部分離工具２４で挟み込むようにして上下方向から応力が加えられる。前記光ファイバテープは上下方向から応力が加えられると、矢印２６方向に応力が働く。   Thereafter, as shown in FIG. 5 (b), the upper separation tool 23 having a flat lower surface is pressed from the upper surface of the optical fiber tape, whereby the optical fiber tape is interposed between the upper separation tool 23 and the intermediate member 25. Stress is applied from above and below so as to be sandwiched by the lower separation tool 24. When stress is applied from above and below to the optical fiber tape, the stress acts in the direction of arrow 26.

その後、図５（ｃ）に示すように、矢印２６方向の応力により、光ファイバ２１と光ファイバ２１の隣接部で、光ファイバ２１と光ファイバ２１の間隔を押し開くようにして光ファイバが分離されると共にテープ樹脂２２は押し潰され破壊されて屑２７となる。   After that, as shown in FIG. 5C, the optical fiber is separated by pushing the gap between the optical fiber 21 and the optical fiber 21 at the adjacent portion of the optical fiber 21 due to the stress in the direction of the arrow 26. At the same time, the tape resin 22 is crushed and broken into scraps 27.

尚、上部分離工具２３と下部分離工具２４の間に光ファイバ２１の直径とほぼ等しい高さの介在部材２５が設置されることにより、上部分離工具２３と下部分離工具２４で光ファイバテープを挟み込むようにして上下方向から応力が加えられても、光ファイバ２１に損傷を与えることはない。   Note that an optical fiber tape is sandwiched between the upper separation tool 23 and the lower separation tool 24 by installing an interposed member 25 having a height substantially equal to the diameter of the optical fiber 21 between the upper separation tool 23 and the lower separation tool 24. Thus, even if stress is applied from above and below, the optical fiber 21 is not damaged.

A height (thickness) interposition member 35 is installed.

その後、図６（ｂ）に示すように、下面が平坦な上部分離工具３３を前記光ファイバテープの上面より押圧することにより、前記光ファイバテープは介在部材３５を介在して上部分離工具３３と下部分離工具３４で挟み込むようにして上下方向から応力が加えられる。前記光ファイバテープは上下方向から応力が加えられると、矢印３６方向に応力が働く。   Thereafter, as shown in FIG. 6B, the upper separation tool 33 having a flat lower surface is pressed from the upper surface of the optical fiber tape, whereby the optical fiber tape is interposed between the upper separation tool 33 and the intermediate member 35. Stress is applied from above and below so as to be sandwiched by the lower separation tool 34. When stress is applied from above and below to the optical fiber tape, the stress acts in the direction of arrow 36.

その後、図６（ｃ）に示すように、矢印３６方向の応力により、光ファイバ３１と光ファイバ３１の隣接部で、光ファイバ３１と光ファイバ３１の間隔を押し開くようにして光ファイバが分離されると共にテープ樹脂３２は押し潰され破壊されて屑３７となる。   After that, as shown in FIG. 6C, the optical fiber is separated by pushing the gap between the optical fiber 31 and the optical fiber 31 at the adjacent portion of the optical fiber 31 by the stress in the direction of the arrow 36. At the same time, the tape resin 32 is crushed and broken into scraps 37.

尚、上部分離工具３３と下部分離工具３４の間に光ファイバ３１の直径とほぼ等しい厚さの介在部材３５が設置されることにより、上部分離工具３３と下部分離工具３４で光ファイバテープを挟み込むようにして上下方向から応力が加えられても、光ファイバ３１に損傷を与えることはない。   Note that an optical fiber tape is sandwiched between the upper separation tool 33 and the lower separation tool 34 by installing an interposed member 35 having a thickness substantially equal to the diameter of the optical fiber 31 between the upper separation tool 33 and the lower separation tool 34. Thus, even if stress is applied from above and below, the optical fiber 31 is not damaged.

図８は本発明の実施形態に係る分離工具を示す一部切欠斜視図である。図８に示すように、上部分離工具２３（３３）は断面コ字状に形成されると共に底面が平坦に形成される。下部分離工具２４（３４）は両側近傍に介在部材（足）２５（３５）が底面より光ファイバ３１の直径とほぼ等しい高さ突出して設けられると共に底面は平坦に形成される。前記下部分離工具２４（３４）の介在部材２５（３５）の外側段部には上部分離工具２３（３３）の開口端が載置される。前記上部分離工具２３（３３）の一方の開口端縁と、前記下部分離工具２４（３４）の一方の開口端縁とは例えば蝶番等の回動部材２８で回動自在に取り付けられる。   FIG. 8 is a partially cutaway perspective view showing the separation tool according to the embodiment of the present invention.

The open end of the upper separation tool 23 (33) is placed on the outer step portion of the interposition member 25 (35) of the lower separation tool 24 (34). One opening edge of the upper separation tool 23 (33) and one opening edge of the lower separation tool 24 (34) are rotatably attached by a rotation member 28 such as a hinge.

図７（ａ），（ｂ）は本発明の第２の実施形態に係る光ファイバテープ単心分離方法を示す構成説明図である。図７（ａ），（ｂ）において、４１は上部分離工具、４２は下部分離工具、４３は介在部材（足）、４４，４５は軟らかいブラシである。   FIGS. 7 (a) and 7 (b) are structural explanatory views showing an optical fiber tape single-core separation method according to the second embodiment of the present invention. 7 (a) and 7 (b), 41 is an upper separating tool, 42 is a lower separating tool, 43 is an interposed member (foot), and 44 and 45 are soft brushes.

図７（ａ）に示すように、下部分離工具４２の上面には複数の軟らかいブラシ４５が植毛されると共に両側に介在部材（足）４３が上方に突出して設けられる。前記ブラシ４５上には図１の光ファイバテープが載置され、前記光ファイバテープの上方には下面に複数の軟らかいブラシ４４が植毛された上部分離工具４１が降下可能にして設けられる。   As shown in FIG. 7A, a plurality of soft brushes 45 are planted on the upper surface of the lower separation tool 42, and intervening members (foot) 43 are provided so as to protrude upward on both sides. The optical fiber tape of FIG. 1 is placed on the brush 45, and an upper separation tool 41 having a plurality of soft brushes 44 implanted on the lower surface is provided above the optical fiber tape so as to be lowered.

It is pushed in this way. The brushes 44 and 45 are pressed so as to be sandwiched between the upper surface and the lower surface of the optical fiber tape, whereby the tip portions of the brushes 44 and 45 enter the gap between the optical fiber 21 and the optical fiber 21 of the optical fiber tape ( Black broken line part). In this state, the optical fiber 21 is separated from the tape resin 22 by repeatedly sliding the separation tool composed of the upper separation tool 41, the lower separation tool 42, and the interposition member (foot) 43 in the longitudinal direction of the optical fiber tape. To do. By using soft brushes (for example, soft toothbrushes) as the brushes 44 and 45, communication troubles can be avoided even if excessive stress is applied to the optical fiber tape during the separation work.
