In other words, the movable table 33 is guided by the two guide shafts 37 and can reciprocate. The movable table 33 is supported between a pair of gripping members 32 on the two guide shafts 37.

ここで、光ファイバテープ心線41は、図2(a)に示すように、隣り合うもの同士が密着するように一列状に並べられた複数の光ファイバ素線47をテープ化材48で被覆して形成されている。本実施形態の光ファイバテープ心線41は、光ファイバ素線47を四本有する四心の光ファイバテープ心線41である。光ファイバテープ心線41では、光ファイバ素線47の延在方向(図2の紙面直交方向)が長さ方向となり、複数の光ファイバ素線47の配列方向(図2の左右方向)が幅方向となり、複数の光ファイバ素線47の配列方向に対して直交する方向(図2の上下方向)が厚さ方向となる。各光ファイバ素線47は、断面円形状に形成され、中央の裸光ファイバ51の周囲を被覆材52で被覆したものである。   Here, as shown in FIG. 2A, the optical fiber ribbon 41 is covered with a taped material 48 so that a plurality of optical fibers 47 arranged in a line so that adjacent ones are in close contact with each other. Is formed. The optical fiber ribbon 41 of this embodiment is a four-fiber ribbon 41 having four optical fiber strands 47. In the optical fiber ribbon 41, the extending direction of the optical fiber 47 (in the direction orthogonal to the drawing in FIG. 2) is the length direction, and the arrangement direction of the optical fiber 47 (the horizontal direction in FIG. 2) is the width. The direction (vertical direction in FIG. 2) perpendicular to the arrangement direction of the plurality of optical fiber wires 47 is the thickness direction. Each of the optical fiber strands 47 is formed in a circular cross section, and the periphery of the central bare optical fiber 51 is covered with a covering material 52.

図1に示す一対の把持部材32は、光ファイバテープ心線41を幅方向に位置決めしつつ厚さ方向両側から挟持する。図1に示す可動台33には装着部53が設けられており、この装着部53に切断工具54が取り付けられている。切断工具54は可動台33の装着部53に対して着脱可能となっている。切断工具54は、光ファイバテープ心線41の一対の被把持部42の間の中間部43を、図2(b)に示すように光ファイバ素線47を一本ずつ含む複数の分離部55に分離する。すなわち、切断工具54は、光ファイバテープ心線41の単心分離を行う工具であり、作業補助装置10は、この切断工具54が取り付けられた状態において、光ファイバテープ心線41の単心分離作業を補助する単心分離補助装置になる。   The pair of gripping members 32 shown in FIG. 1 hold the optical fiber ribbon 41 from both sides in the thickness direction while positioning in the width direction. The movable base 33 shown in FIG. 1 is provided with a mounting portion 53, and a cutting tool 54 is attached to the mounting portion 53. The cutting tool 54 can be attached to and detached from the mounting portion 53 of the movable base 33. The cutting tool 54 includes a plurality of separating portions 55 each including an intermediate portion 43 between the pair of gripped portions 42 of the optical fiber ribbon 41 and one optical fiber 47 as shown in FIG. To separate. That is, the cutting tool 54 is a tool for performing single-core separation of the optical fiber tape core 41, and the work auxiliary device 10 separates the single-fiber separation of the optical fiber tape core 41 in a state where the cutting tool 54 is attached. It becomes a single-fiber separation assist device that assists work.

切断工具54は、光ファイバテープ心線41を幅方向に位置決めした状態で厚さ方向の両側から挟むことで、隣り合う光ファイバ素線47の間に切れ込む刃を有する。切断工具54の刃は、複数の光ファイバ素線47の各間に位置するように設けられている。
可動台33の装着部53に取り付けられた切断工具54によって光ファイバテープ心線41を厚さ方向両側から挟み、この状態で、手動により切断工具54を可動台33と共に二本のガイド軸37の案内で移動させる。これにより、光ファイバテープ心線41は、図2(a)及び図2(b)に示すように、テープ化材48の複数箇所が切断されて光ファイバ素線47を一本ずつ含む複数(本実施形態では四つ)の分離部55に分離される。その際に形成される切断面は、光ファイバテープ心線41の幅方向に対して直交する。
The cutting tool 54 has a blade that cuts between adjacent optical fiber strands 47 by sandwiching the optical fiber ribbon 41 from both sides in the thickness direction with the optical fiber tape core wire 41 positioned in the width direction. The blade of the cutting tool 54 is provided so as to be positioned between each of the plurality of optical fiber strands 47.
The optical fiber ribbon 41 is sandwiched from both sides in the thickness direction by the cutting tool 54 attached to the mounting portion 53 of the movable table 33. In this state, the cutting tool 54 is manually moved along with the movable table 33 to the two guide shafts 37. Move by guidance. Thereby, as shown in FIG. 2A and FIG. 2B, the optical fiber ribbon 41 has a plurality of optical fiber strands 47 one by one by cutting a plurality of portions of the taped material 48 (see FIG. 2A and FIG. 2B). In the present embodiment, it is separated into four separation portions 55. The cut surface formed at that time is orthogonal to the width direction of the optical fiber ribbon 41.

光ファイバテープ心線41のうち、その延在方向における複数の分離部55の両側部分は、分離前と同様に、複数の光ファイバ素線47をテープ化材48で被覆して纏めた非分離部56(図1参照)となっている。光ファイバケーブル11から引き出された光ファイバテープ心線41のうちの少なくとも一対の把持部材32で把持される被把持部42から外側が、この非分離部56となっている。   In the optical fiber ribbon 41, both side portions of the plurality of separating portions 55 in the extending direction are unseparated by covering a plurality of optical fiber strands 47 with a taped material 48 in the same manner as before separation. This is part 56 (see FIG. 1). The non-separating portion 56 is located outside the gripped portion 42 gripped by at least one pair of gripping members 32 of the optical fiber tape core wire 41 drawn out from the optical fiber cable 11.

作業補助装置10は、上述したように、光ファイバテープ心線41を、光ファイバ素線47を一本ずつ含む複数(本実施形態では四つ)の分離部55に分離する際に用いられることに加え、光ファイバ素線47を一本ずつ含んで分離された複数の分離部55のテープ化材48を光ファイバ素線47から剥離させる際にも用いられる。   As described above, the work auxiliary device 10 is used when separating the optical fiber ribbon 41 into a plurality of (four in the present embodiment) separation portions 55 each including one optical fiber 47. In addition, it is also used when the taped material 48 of the plurality of separating portions 55 separated by including one optical fiber 47 is separated from the optical fiber 47.

図1に示すように、作業補助装置10は、ガイド部材31の二本のガイド軸37に取り付けられる含浸部材61を有している。本実施形態の作業補助装置10は、含浸部材61を複数(図示例では二つ)有している。含浸部材61は、二本のガイド軸37に対して着脱可能である。含浸部材61は、二本のガイド軸37に取り付けられてこれらから光ファイバケーブル11に向けて延出する一対の延出部62と、これら延出部62にそれぞれの延出先端部同士を結ぶように架設された直線状の保持部63とを有している。含浸部材61は、図3に示すように、二本のガイド軸37間に一対の延出部62の基端部分を嵌合させることで二本のガイド軸37に取り付けられ、二本のガイド軸37間から延出部62の基端部分を引き抜くことで二本のガイド軸37から取り外される。   As shown in FIG. 1, the work assisting device 10 includes an impregnation member 61 attached to the two guide shafts 37 of the guide member 31. The work auxiliary device 10 of the present embodiment has a plurality of impregnation members 61 (two in the illustrated example). The impregnating member 61 can be attached to and detached from the two guide shafts 37. The impregnating member 61 is attached to the two guide shafts 37 and extends from the pair toward the optical fiber cable 11, and the extending tip ends are connected to the extending portions 62. And a linear holding portion 63 erected in this manner. As shown in FIG. 3, the impregnating member 61 is attached to the two guide shafts 37 by fitting the base end portions of the pair of extending portions 62 between the two guide shafts 37, and the two guide shafts 37 are attached. By pulling out the base end portion of the extending portion 62 from between the shafts 37, the two guide shafts 37 are removed.

保持部63は、液体である膨潤剤が染み込ませられると、この膨潤剤を保持することが可能な多孔質体からなる。膨潤剤は、テープ化材48を膨潤させる一方、光ファイバ素線47(被覆材52)をほぼ膨潤させることがないものである。また、膨潤剤は、例えば膨潤剤をテープ化材48に含浸させたときのテープ化材48の膨張率が、膨潤剤を光ファイバ素線47に含浸させたときの光ファイバ素線47(被覆材52)の膨張率よりも大きい特性を有してもよい。また、膨潤剤は、例えば、テープ化材48と光ファイバ素線47との接着面に浸透してテープ化材48の光ファイバ素線47からの剥離を促進する。   The holding part 63 is made of a porous body capable of holding the swelling agent when the swelling agent which is a liquid is infiltrated. The swelling agent swells the tape forming material 48, but does not substantially swell the optical fiber 47 (coating material 52). Further, the swelling agent is, for example, an optical fiber strand 47 (coating when the expansion factor of the tape forming material 48 when the swelling material 48 is impregnated with the swelling agent is impregnated with the optical fiber strand 47 when the swelling agent is impregnated with the swelling agent. It may have characteristics that are greater than the expansion coefficient of the material 52). Further, the swelling agent, for example, penetrates the bonding surface between the tape forming material 48 and the optical fiber strand 47 and promotes the peeling of the tape forming material 48 from the optical fiber strand 47.

図1に示すように、複数の含浸部材61を、ガイド部材31の二本のガイド軸37にそれぞれ装着すると、これら含浸部材61は、一対の把持部材32の間に位置決めされて張設された光ファイバテープ心線41の複数の分離部55に保持部63を下から接触させるようになっている。その結果、複数の含浸部材61は、保持部63に保持している膨潤剤を複数の分離部55に含浸させることになる。   As shown in FIG. 1, when a plurality of impregnation members 61 are respectively attached to the two guide shafts 37 of the guide member 31, the impregnation members 61 are positioned and stretched between the pair of gripping members 32. A holding portion 63 is brought into contact with the plurality of separating portions 55 of the optical fiber ribbon 41 from below. As a result, the plurality of impregnation members 61 impregnate the plurality of separation portions 55 with the swelling agent held in the holding portion 63.

可動台33の装着部53には、図4に示す剥離部材71が取り付け可能となっている。剥離部材71は、可動台33の装着部53に対して着脱可能であり、上述した切断工具54と交換可能である。剥離部材71は、可動台33に取り付けられて可動台33と共に二本のガイド軸37の案内で往復移動可能となる。剥離部材71は、可動台33の装着部53に装着された状態で、一対の把持部材32の間に位置決めされて張設された光ファイバテープ心線41の複数の分離部55を、光ファイバテープ心線41の厚さ方向両側から図5に示すように挟む。剥離部材71は、この状態で、手動により可動台33と共に二本のガイド軸37の案内で往復移動可能である。剥離部材71は、複数の分離部55を挟持した状態で上記のように移動することにより、複数の分離部55を擦って(しごいて)テープ化材48を複数の光ファイバ素線47から剥離させる。   A peeling member 71 shown in FIG. 4 can be attached to the mounting portion 53 of the movable base 33. The peeling member 71 can be attached to and detached from the mounting portion 53 of the movable table 33 and can be replaced with the cutting tool 54 described above. The peeling member 71 is attached to the movable base 33 and can be reciprocated by the guide of the two guide shafts 37 together with the movable base 33. In the state where the peeling member 71 is mounted on the mounting portion 53 of the movable base 33, the plurality of separating portions 55 of the optical fiber ribbon 41 that are positioned and stretched between the pair of gripping members 32 are connected to the optical fiber. The tape core 41 is sandwiched from both sides in the thickness direction as shown in FIG. In this state, the peeling member 71 can be reciprocated by the guide of the two guide shafts 37 together with the movable base 33 manually. The peeling member 71 moves as described above while sandwiching the plurality of separation portions 55, thereby rubbing (squeezing) the plurality of separation portions 55 to remove the taped material 48 from the plurality of optical fiber strands 47. Remove.

剥離部材71は、剥離部材本体72と、クリップ73と、一対の面ファスナ74と、一対のヤスリ部材75とを有している。剥離部材本体72は、図6に示すようにV字状の部材であり、一対の腕部81と、一対の腕部81を連結する基端連結部82と、一対の腕部81の基端連結部82とは反対側に設けられた一対の挟持部83とを有している。剥離部材本体72は、主に可撓性を有する基端連結部82が弾性変形することで一対の腕部81同士を近接離間させる。一対の腕部81は、これに外力が作用していない自然状態において、図6に示すように互いに最も離間した開状態となり、この開状態で鋭角をなす。また、一対の腕部81は、外力により弾性変形させられて最も近接した閉状態になると、図5に示すように互いに対向する当接面81aにおいて互いに当接する。   The peeling member 71 includes a peeling member main body 72, a clip 73, a pair of surface fasteners 74, and a pair of file members 75. The peeling member main body 72 is a V-shaped member as shown in FIG. 6, and includes a pair of arm portions 81, a base end connecting portion 82 that connects the pair of arm portions 81, and a base end of the pair of arm portions 81. It has a pair of clamping parts 83 provided on the opposite side to the connecting part 82. The peeling member main body 72 brings the pair of arm portions 81 close to and away from each other mainly by elastically deforming the base end connecting portion 82 having flexibility. In a natural state where no external force is applied to the pair of arm portions 81, the pair of arm portions 81 are in an open state that is most separated from each other as shown in FIG. 6, and form an acute angle in this open state. Further, when the pair of arms 81 are elastically deformed by an external force and are in the closest closed state, they come into contact with each other on the contact surfaces 81a facing each other as shown in FIG.

一方の挟持部83のうち他方の挟持部83に対向する対向面83aは、一方の挟持部83に繋がる一方の腕部81の当接面81aよりも、他方の挟持部83とは反対側にオフセットしている。同様にして、他方の挟持部83のうち一方の挟持部83に対向する対向面83aは、この他方の挟持部83に繋がる他方の腕部81の当接面81aよりも、一方の挟持部83とは反対側にオフセットしている。このため、互いに対向する一対の挟持部83の対向面83a同士は、一対の腕部81が閉状態のときに互いに最も近接した状態になるが、所定の間隔をあけて互いに平行する。すなわち、一対の挟持部83が互いに当接することはない。   The opposing surface 83a of the one clamping part 83 that faces the other clamping part 83 is on the opposite side of the other clamping part 83 from the abutment surface 81a of one arm part 81 connected to the one clamping part 83. It is offset. Similarly, the opposing surface 83a of the other clamping part 83 that faces the one clamping part 83 is one clamping part 83 than the contact surface 81a of the other arm part 81 that is connected to the other clamping part 83. Offset to the opposite side. For this reason, the opposing surfaces 83a of the pair of sandwiching portions 83 facing each other are in a state of being closest to each other when the pair of arm portions 81 are in the closed state, but are parallel to each other with a predetermined interval. That is, the pair of clamping parts 83 do not contact each other.

ヤスリ部材75は、面ファスナ74によって挟持部83の対向面83aに対して着脱可能に取り付けられる。具体的には、面ファスナ74の一方のシートを挟持部83の対向面83aに貼着し、面ファスナ74の他方のシートをヤスリ部材75の裏面に貼着した上で、これら面ファスナ74の二枚のシート同士を着けたり剥がしたりすることで、ヤスリ部材75が挟持部83に対して着脱可能となる。   The file member 75 is detachably attached to the facing surface 83a of the clamping portion 83 by a surface fastener 74. Specifically, after attaching one sheet of the hook-and-loop fastener 74 to the opposing surface 83a of the clamping portion 83 and sticking the other sheet of the hook-and-loop fastener 74 to the back surface of the file member 75, The file member 75 can be attached to and detached from the clamping portion 83 by attaching or removing the two sheets.

ヤスリ部材75は、例えば光ファイバ素線47よりも軟らかい素材からなる。ヤスリ部材75の表面は、粗さの粗い粗面75aとなっている。一対のヤスリ部材75が各挟持部83に取り付けられた状態では、ヤスリ部材75の粗面75aが互いに対向する。また、一対の腕部81の当接面81a同士が当接すると、一対のヤスリ部材75の粗面75a同士も同様に互いに平行した状態で接触する。
剥離部材71を可動台33の装着部53に取り付けた状態で、一対の粗面75a同士が接触する位置は、一対の把持部材32間に位置決めされて張設された光ファイバテープ心線41の複数の分離部55の位置と一致する。これにより、一対のヤスリ部材75の粗面75aの間に複数の分離部55を挟持することができる。また、互いに接触する一対の粗面75aは、例えば一対の把持部材32間に張設された光ファイバテープ心線41の厚さ方向(図5の上下方向)に直交する。これにより、複数の分離部55をヤスリ部材75の粗面75aに対して均等に接触させることができる。
The file member 75 is made of a material softer than the optical fiber 47, for example. The surface of the file member 75 is a rough surface 75a having a rough roughness. In a state where the pair of file members 75 are attached to the respective clamping portions 83, the rough surfaces 75a of the file members 75 face each other. Further, when the contact surfaces 81a of the pair of arm portions 81 are in contact with each other, the rough surfaces 75a of the pair of file members 75 are also in contact with each other in a parallel state.
In a state in which the peeling member 71 is attached to the mounting portion 53 of the movable base 33, the position where the pair of rough surfaces 75a come into contact with each other is the position of the optical fiber tape core wire 41 that is positioned and stretched between the pair of gripping members 32. It coincides with the position of the plurality of separation portions 55. Thereby, the some separation | separation part 55 can be clamped between the rough surfaces 75a of a pair of file member 75. FIG. Further, the pair of rough surfaces 75a that are in contact with each other are orthogonal to the thickness direction (vertical direction in FIG. 5) of the optical fiber ribbon 41 stretched between the pair of gripping members 32, for example. Thereby, the some isolation | separation part 55 can be made to contact with the rough surface 75a of the file member 75 equally.

クリップ73は、コ字状の部材であり、互いに平行な一対の押さえ部86と、これら押さえ部86の長さ方向の一端同士を連結するベース部87とを有している。クリップ73は、剥離部材本体72よりも剛性が高く、閉状態にある一対の腕部81の両外側に一対の押さえ部86が配置されることで、一対の腕部81(剥離部材本体72)を閉状態に維持する。クリップ73によって一対の腕部81が閉状態に維持された剥離部材本体72では、一対のヤスリ部材75が、一対の把持部材32間に位置決めされて張設された光ファイバテープ心線41の複数の分離部55を、光ファイバテープ心線41の厚さ方向の両側から所定の押圧力で押圧する。   The clip 73 is a U-shaped member, and includes a pair of pressing portions 86 that are parallel to each other and a base portion 87 that connects one ends of the pressing portions 86 in the length direction. The clip 73 has higher rigidity than the peeling member main body 72, and a pair of pressing portions 86 are disposed on both outer sides of the pair of arm portions 81 in a closed state, so that the pair of arm portions 81 (the peeling member main body 72). Is kept closed. In the peeling member main body 72 in which the pair of arm portions 81 is maintained in the closed state by the clip 73, a plurality of the optical fiber tape core wires 41 in which the pair of file members 75 are positioned and stretched between the pair of gripping members 32 are provided. The separation portion 55 is pressed with a predetermined pressing force from both sides in the thickness direction of the optical fiber ribbon 41.

次に、光ファイバテープ心線41の複数の光ファイバ素線47からテープ化材48を剥離させるテープ化材剥離方法について説明する。   Next, a taped material peeling method for peeling the taped material 48 from the plurality of optical fiber strands 47 of the optical fiber ribbon 41 will be described.

まず、図1に示すように、作業補助装置10をその一対の連結部36によってクロージャ12の架設部23に取り付ける。この状態で、多条の光ファイバケーブル11の内部配置部21から引き出された光ファイバテープ心線41の長さ方向に離間する二箇所の被把持部42を一対の把持部材32に把持させる。その際に、一対の把持部材32が、これらの把持部材32の間となる光ファイバテープ心線41の中間部43をテンションをかけつつ直線状に支持する状態とする。また、これと前後して、切断工具54を可動台33に取り付ける。   First, as shown in FIG. 1, the work assisting device 10 is attached to the installation portion 23 of the closure 12 by the pair of connecting portions 36. In this state, two gripped portions 42 that are separated from each other in the length direction of the optical fiber ribbon 41 drawn from the internal arrangement portion 21 of the multiple optical fiber cable 11 are gripped by the pair of gripping members 32. At this time, the pair of gripping members 32 are in a state of supporting the intermediate portion 43 of the optical fiber tape core wire 41 between the gripping members 32 in a straight line while applying tension. Further, the cutting tool 54 is attached to the movable base 33 before and after this.

そして、光ファイバテープ心線41の二箇所の被把持部42の間の中間部43を切断工具54で厚さ方向両側から挟み、この状態で、手動により切断工具54を可動台33と共に二本のガイド軸37の案内で移動させる。これにより、光ファイバテープ心線41が、図2(a)及び図2(b)に示すように、光ファイバ素線47を一本ずつ含む複数(本実施形態では四つ)の分離部55に分離される。以上が、光ファイバテープ心線41を、光ファイバ素線47を一本ずつ含む複数の分離部55に分離する分離工程である。分離工程後には、切断工具54を可動台33から取り外す。   Then, an intermediate portion 43 between the two gripped portions 42 of the optical fiber ribbon 41 is sandwiched by the cutting tool 54 from both sides in the thickness direction, and in this state, two cutting tools 54 are moved together with the movable base 33 manually. The guide shaft 37 is moved. Accordingly, as shown in FIGS. 2A and 2B, the optical fiber ribbon 41 has a plurality of (four in the present embodiment) separating portions 55 each including one optical fiber 47. Separated. The above is the separation process of separating the optical fiber ribbon 41 into a plurality of separation parts 55 each including one optical fiber 47. After the separation step, the cutting tool 54 is removed from the movable base 33.

次に、複数の含浸部材61を、ガイド部材31の二本のガイド軸37のうち一対の把持部材32の間の部分に装着する。これにより、一対の把持部材32間に張設された光ファイバテープ心線41の複数の分離部55が、複数の含浸部材61の保持部63に接触する。また、含浸部材61の装着の前後に、含浸部材61の保持部63に、テープ化材48を膨潤させる膨潤剤を注入し保持させる。これにより、含浸部材61は、保持部63に保持している膨潤剤を、光ファイバテープ心線41の二箇所の被把持部42の間の中間部43にある複数の分離部55に含浸させる。   Next, the plurality of impregnating members 61 are attached to the portion between the pair of gripping members 32 of the two guide shafts 37 of the guide member 31. As a result, the plurality of separation portions 55 of the optical fiber ribbon 41 stretched between the pair of gripping members 32 come into contact with the holding portions 63 of the plurality of impregnation members 61. Further, before and after the impregnation member 61 is mounted, a swelling agent that swells the taped material 48 is injected and held in the holding portion 63 of the impregnation member 61. Thus, the impregnation member 61 impregnates the plurality of separation portions 55 in the intermediate portion 43 between the two gripped portions 42 of the optical fiber tape core wire 41 with the swelling agent held in the holding portion 63. .

このように複数の分離部55に膨潤剤を含浸させる状態で、所定時間(例えば5分〜10分、より好ましくは7分程度)の経過を待つ。これにより、膨潤剤がテープ化材48に染み込んでこれを膨潤させる。加えて、膨潤剤は、例えば、テープ化材48と光ファイバ素線47との接着面に浸透してテープ化材48の光ファイバ素線47からの剥離を促進する。一方、光ファイバ素線47の被覆材52は、膨潤剤が染み込みにくく膨潤することはない。以上が、複数の分離部55に、テープ化材48を膨潤させる膨潤剤を含浸させる含浸工程である。なお、複数の分離部55のうち複数の含浸部材61の間にある部分については、含浸部材61から膨潤剤が毛細管現象により浸透し、含浸部材61の保持部63に接触する部分とほぼ同様に、膨潤し、テープ化材48の光ファイバ素線47からの剥離が促進される。   In this manner, a predetermined time (for example, about 5 minutes to 10 minutes, more preferably about 7 minutes) is awaited in a state where the plurality of separation portions 55 are impregnated with the swelling agent. Thereby, the swelling agent soaks into the tape forming material 48 and swells it. In addition, the swelling agent permeates, for example, the bonding surface between the tape forming material 48 and the optical fiber strand 47 and promotes the peeling of the tape forming material 48 from the optical fiber strand 47. On the other hand, the covering material 52 of the optical fiber 47 does not soak into the swelling agent and does not swell. The above is the impregnation step of impregnating the plurality of separation portions 55 with the swelling agent that swells the taped material 48. It should be noted that the portion between the plurality of impregnation members 61 among the plurality of separation portions 55 is substantially the same as the portion where the swelling agent permeates from the impregnation member 61 by capillary action and contacts the holding portion 63 of the impregnation member 61. Swell, and the peeling of the taped material 48 from the optical fiber 47 is promoted.

ここで、具体的な材質の例をあげると、光ファイバテープ心線41のテープ化材48は、例えばアクリル樹脂からなり、膨潤剤は、アルコール等の溶剤である例えばエタノールである。また、光ファイバ素線47の被覆材52は、エタノールの影響を受けにくい例えば紫外線硬化樹脂からなる。裸光ファイバ51はガラスからなる。   Here, as an example of a specific material, the taped material 48 of the optical fiber ribbon 41 is made of, for example, an acrylic resin, and the swelling agent is, for example, ethanol which is a solvent such as alcohol. The covering material 52 of the optical fiber 47 is made of, for example, an ultraviolet curable resin that is not easily affected by ethanol. The bare optical fiber 51 is made of glass.

上記の含浸工程では、膨潤剤によりテープ化材48が膨潤することによって、このテープ化材48と膨潤しない光ファイバ素線47との間に剥離を生じる。また、仮に光ファイバ素線47(被覆材52)が膨潤剤により若干膨潤したとしても、膨潤剤によるテープ化材48の膨張率が光ファイバ素線47(被覆材52)の膨張率よりも大きいことで、この膨張率の違いによって光ファイバ素線47とテープ化材48との間に剥離を生じる。また、図2(a)に示すように、分離工程前の光ファイバテープ心線41は、複数の光ファイバ素線47が隣り合うもの同士が接触する状態で一列状に並んでいることから、分離工程で分離された複数の分離部55では、図2(b)に示すように、それぞれの光ファイバ素線47の一部が外部に露出する。言い換えれば、すべての分離部55では、光ファイバ素線47とテープ化材48との境界である接着面の一部が外部に露出する。このため、接着面には膨潤剤が浸透しやすく、接着面の膨潤剤による剥離が促進される。   In the above impregnation step, the taped material 48 is swollen by the swelling agent, so that peeling occurs between the taped material 48 and the non-swelled optical fiber strand 47. Even if the optical fiber 47 (coating material 52) is slightly swollen by the swelling agent, the expansion coefficient of the tape forming material 48 by the swelling agent is larger than the expansion coefficient of the optical fiber 47 (coating material 52). Thus, peeling occurs between the optical fiber 47 and the taped material 48 due to the difference in expansion coefficient. Further, as shown in FIG. 2 (a), the optical fiber tape cores 41 before the separation step are arranged in a line in a state in which the adjacent optical fiber strands 47 are in contact with each other. In the plurality of separation portions 55 separated in the separation step, as shown in FIG. 2B, a part of each optical fiber strand 47 is exposed to the outside. In other words, in all the separating portions 55, a part of the bonding surface that is a boundary between the optical fiber 47 and the taped material 48 is exposed to the outside. For this reason, the swelling agent easily penetrates into the adhesive surface, and the peeling of the adhesive surface with the swelling agent is promoted.

次に、複数の含浸部材61をガイド部材31から取り外し、図4及び図6に示すように可動台33に剥離部材本体72を取り付ける。そして、図5に示すように剥離部材本体72を閉状態とすると、光ファイバテープ心線41のうち一対の把持部材32の間に張設された中間部43にある複数の分離部55を光ファイバテープ心線41の厚さ方向両側から一対のヤスリ部材75が粗面75aで挟むことになる。この状態で、剥離部材本体72にクリップ73を装着して剥離部材本体72の閉状態を維持する。すると、剥離部材71は、一対のヤスリ部材75の粗面75aで複数の分離部55を光ファイバテープ心線41の厚さ方向両側から所定の押圧力で挟むことになる。この押圧力は、一対のヤスリ部材75の粗面75aが平行をなすことにより、複数の分離部55のそれぞれに対してほぼ均等になる。   Next, the plurality of impregnation members 61 are removed from the guide member 31, and the peeling member main body 72 is attached to the movable base 33 as shown in FIGS. Then, when the peeling member main body 72 is closed as shown in FIG. 5, the plurality of separation portions 55 in the intermediate portion 43 stretched between the pair of gripping members 32 of the optical fiber tape core wire 41 are light-transmitted. A pair of file members 75 are sandwiched between the rough surfaces 75a from both sides of the fiber tape core wire 41 in the thickness direction. In this state, the clip 73 is attached to the peeling member main body 72 and the closed state of the peeling member main body 72 is maintained. Then, the peeling member 71 sandwiches the plurality of separating portions 55 with a predetermined pressing force from both sides in the thickness direction of the optical fiber ribbon 41 between the rough surfaces 75a of the pair of file members 75. This pressing force is substantially equal to each of the plurality of separation portions 55 by making the rough surfaces 75a of the pair of file members 75 parallel.

剥離部材71が、複数の分離部55を所定の押圧力で挟んだ状態で、手動により可動台33と共に二本のガイド軸37の案内で往復移動させられる。すると、剥離部材71は、複数の分離部55を粗面75aで引っかけるように擦ってテープ化材48を複数の光ファイバ素線47から剥離させる。以上が、複数の分離部55を擦ってテープ化材48を複数の光ファイバ素線47から剥離させる剥離工程である。具体的には、剥離部材71を数回(例えば5回)往復移動させることで、テープ化材48が複数の光ファイバ素線47から剥離する。   The peeling member 71 is manually reciprocated by the guides of the two guide shafts 37 together with the movable base 33 in a state where the plurality of separating portions 55 are sandwiched with a predetermined pressing force. Then, the peeling member 71 rubs the plurality of separating portions 55 so as to be hooked by the rough surface 75 a to peel the taped material 48 from the plurality of optical fiber strands 47. The above is the peeling process in which the taped material 48 is peeled from the plurality of optical fiber wires 47 by rubbing the plurality of separation portions 55. Specifically, the taped material 48 is peeled from the plurality of optical fiber strands 47 by reciprocating the peeling member 71 several times (for example, 5 times).

以上の分離工程、含浸工程および剥離工程は、光ファイバテープ心線41のうち一対の把持部材32で把持された二箇所の被把持部42の間の中間部43に対して施工される。   The above separation process, impregnation process and peeling process are applied to the intermediate portion 43 between the two gripped portions 42 gripped by the pair of gripping members 32 in the optical fiber ribbon 41.

ここで、図2(b)に示すように、配列方向の中間にある光ファイバ素線47を含む分離部55では、テープ化材48からなる部分が光ファイバテープ心線41の幅方向両側に互いに離間して配置されていることから、例えば含浸工程を含まなくても、剥離工程の実施によりテープ化材48を比較的容易かつ良好に光ファイバ素線47から剥離し得る。   Here, as shown in FIG. 2 (b), in the separation part 55 including the optical fiber 47 in the middle of the arrangement direction, the portions made of the taped material 48 are on both sides in the width direction of the optical fiber ribbon 41. Since they are spaced apart from each other, for example, the taped material 48 can be peeled off from the optical fiber 47 relatively easily and satisfactorily by carrying out the peeling step without including the impregnation step.

一方、配列方向の両端にある光ファイバ素線47を含む分離部55では、テープ化材48からなる部分が光ファイバ素線47を包み込むように配置されている。このため、含浸工程を含まずに、単に剥離工程を実施するだけでは、テープ化材48が光ファイバ素線47から剥がれにくい。これに対して、本実施形態は上記の含浸工程を含んでいることで、膨潤剤によりテープ化材48が膨潤して光ファイバ素線47との間に剥離を生じる。加えて、図2(c)に示すように、テープ化材48は膨潤によって切断面側の離間した部分同士がさらに距離を大きくして光ファイバ素線47を包み込む量を減少させて光ファイバ素線47の露出量を拡大する。これにより、配列方向の両端にある光ファイバ素線47を含む分離部55についても、剥離工程の実施により、テープ化材48を容易かつ良好に光ファイバ素線47から剥離できる。   On the other hand, in the separation part 55 including the optical fiber strands 47 at both ends in the arrangement direction, the portion made of the taped material 48 is disposed so as to wrap the optical fiber strands 47. For this reason, the taped material 48 is not easily peeled off from the optical fiber 47 by simply performing the peeling step without including the impregnation step. On the other hand, this embodiment includes the above-described impregnation step, so that the taped material 48 is swollen by the swelling agent, and the optical fiber 47 is peeled off. In addition, as shown in FIG. 2 (c), the taped material 48 is further swelled to increase the distance between the separated portions on the cut surface side so as to reduce the amount of wrapping the optical fiber 47, thereby reducing the optical fiber element. The exposure amount of the line 47 is enlarged. As a result, the taped material 48 can be easily and satisfactorily peeled off from the optical fiber strand 47 by performing the peeling step for the separating portions 55 including the optical fiber strands 47 at both ends in the arrangement direction.

上記の剥離工程において、剥離部材71を往復移動させると、複数の分離部55において光ファイバ素線47から剥離されたテープ化材48は、剥離部材71で引っ張られて一側が切断される。その後、テープ化材48の他側が例えば手作業等で切断されることで、テープ化材48が光ファイバテープ心線41から除去される。その後、露出した光ファイバ素線47に対しては、例えば、心線対照器が取り付けられて対照関係を把握する作業等が行われる。   When the peeling member 71 is reciprocated in the peeling step, the taped material 48 peeled from the optical fiber 47 in the plurality of separating portions 55 is pulled by the peeling member 71 and one side is cut. Thereafter, the other side of the tape forming material 48 is cut by, for example, manual work, so that the tape forming material 48 is removed from the optical fiber ribbon 41. Thereafter, the exposed optical fiber 47 is attached with, for example, a core wire contrast device, and the work of grasping the contrast is performed.

以上説明したように、本実施形態のテープ化材剥離方法によれば、分離工程にて、光ファイバテープ心線41を、光ファイバ素線47を一本ずつ含む複数の分離部55に分離した後に、含浸工程にて、複数の分離部55に、テープ化材48を膨潤させる膨潤剤を含浸させる。これにより、膨潤剤により膨潤するテープ化材48と光ファイバ素線47との間に剥離を生じる。その後、剥離工程にて、複数の分離部55を擦ってテープ化材48を複数の光ファイバ素線47から剥離させる。これにより、容易かつ良好に光ファイバ素線47からテープ化材48を剥離させることができる。したがって、熟練度を要することなくテープ化材48の剥離作業を行うことができる。その結果として、多くの作業者が作業を担当できることになり、短時間で作業することができる。このテープ化材剥離方法においては、例えば、膨潤剤を染みこませた布等を複数の分離部55に巻き付けて、複数の分離部55に膨潤剤を含浸させても良い。   As described above, according to the taped material peeling method of this embodiment, in the separation step, the optical fiber ribbon 41 is separated into a plurality of separation portions 55 each including one optical fiber 47. Later, in the impregnation step, the plurality of separation portions 55 are impregnated with a swelling agent that swells the taped material 48. Thereby, peeling occurs between the taped material 48 swollen by the swelling agent and the optical fiber 47. Thereafter, in the peeling step, the taped material 48 is peeled from the plurality of optical fiber strands 47 by rubbing the plurality of separating portions 55. Thereby, the taped material 48 can be peeled off from the optical fiber 47 easily and satisfactorily. Therefore, the tape material 48 can be peeled without requiring skill. As a result, many workers can take charge of work, and work can be performed in a short time. In this tape forming material peeling method, for example, a cloth soaked with a swelling agent may be wound around the plurality of separation portions 55 and the plurality of separation portions 55 may be impregnated with the swelling agent.

また、含浸部材61と剥離部材71とを有するテープ化材剥離用部材キットによれば、含浸部材61にテープ化材48を膨潤させる膨潤剤を保持して含浸部材61を複数の分離部55に接触させることにより、複数の分離部55に膨潤剤を含浸させることができる。その後、剥離部材71を、複数の分離部55を挟持した状態で移動させると、剥離部材71が複数の分離部55を擦ってテープ化材48を複数の光ファイバ素線47から剥離させる。よって、容易かつ良好に光ファイバ素線47からテープ化材48を剥離させることが可能となる。   Further, according to the taped material peeling member kit having the impregnating member 61 and the peeling member 71, the impregnating member 61 holds the swelling agent that swells the taped material 48, and the impregnating member 61 is separated into the plurality of separating portions 55. By bringing them into contact, the plurality of separating portions 55 can be impregnated with the swelling agent. Thereafter, when the peeling member 71 is moved in a state where the plurality of separating portions 55 are sandwiched, the peeling member 71 rubs the plurality of separating portions 55 to peel the taped material 48 from the plurality of optical fiber strands 47. Therefore, the taped material 48 can be peeled off from the optical fiber 47 easily and satisfactorily.

例えば、光ファイバ素線47に大きな曲げやひねり等を生じることなくテープ化材48を剥離させることができるため、活線状態にあっても、使用に及ぼす影響(伝送損失の増加や断線の発生)を抑制しつつ光ファイバ素線47からテープ化材48を剥離させることができる。つまり、従来は、使用中でない光ファイバテープ心線41について行っていたテープ化材48の光ファイバ素線47からの剥離作業を、使用中の光ファイバテープ心線41についても行うことができる。   For example, since the taped material 48 can be peeled off without causing a large bend or twist in the optical fiber 47, the influence on use even in a live state (increased transmission loss or occurrence of disconnection). ), The taped material 48 can be peeled off from the optical fiber 47. That is, conventionally, the stripping work of the taped material 48 from the optical fiber 47 that has been performed on the optical fiber ribbon 41 that is not in use can be performed on the optical fiber ribbon 41 in use.

以上、本発明の詳細について説明したが、本発明は上述した実施形態に限定されるものではなく、本発明の主旨を逸脱しない範囲において種々の変更を加えることができる。   Although the details of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

例えば、上記したテープ化材剥離方法では、分離工程後、かつ、含浸工程前に、複数の分離部55を擦ってテープ化材48に傷をつける引っ掻き工程を行ってもよい。引っ掻き工程では、例えば前述した剥離工程と同様に剥離部材71を用いて複数の分離部55を擦ることで、テープ化材48に傷をつけることができる。この場合には、引っ掻き工程後の含浸工程において、膨潤剤がテープ化材48の傷に入り込むため、膨潤剤を効果的にテープ化材48に染み込ませることができる。すなわち、テープ化材48の膨潤を促進できる。したがって、剥離工程においてさらに容易にテープ化材48を光ファイバ素線47から剥離できる。   For example, in the tape material peeling method described above, a scratching step of scratching the tape material 48 by rubbing the plurality of separation portions 55 after the separation step and before the impregnation step may be performed. In the scratching process, for example, the taped material 48 can be damaged by rubbing the plurality of separation portions 55 using the peeling member 71 in the same manner as the above-described peeling process. In this case, in the impregnation step after the scratching step, the swelling agent enters the wound of the tape forming material 48, so that the swelling agent can be effectively infiltrated into the tape forming material 48. That is, the swelling of the tape forming material 48 can be promoted. Therefore, the taped material 48 can be peeled off from the optical fiber 47 more easily in the peeling step.

以上においては、長さ方向に連続する状態の複数の分離部55の光ファイバ素線47からテープ化材48を剥離させる場合を例として説明したが、本発明は、例えば長さ方向に切断された複数の分離部55の切断側の端部について光ファイバ素線47からテープ化材48を剥離させる場合にも適用可能である。   In the above, the case where the taped material 48 is peeled off from the optical fiber strands 47 of the plurality of separating portions 55 in a state continuous in the length direction has been described as an example. Further, the present invention can also be applied to the case where the taped material 48 is peeled off from the optical fiber strand 47 at the cut end portions of the plurality of separating portions 55.
