Description

本発明は、光通信に用いられる光ファイバーの外周を傷や汚れから守り、曲げによる破損を防止するために、保護チューブ内に光ファイバーを挿入することを目的とする装置に関する。   The present invention relates to an apparatus intended to insert an optical fiber into a protective tube in order to protect the outer periphery of the optical fiber used for optical communication from scratches and dirt, and to prevent breakage due to bending.

通信用の光ファイバーは屈曲性に乏しく、また外周の傷や汚れが光ファイバーの性能を落とすことから、外周を長さ1m程度のプラスチックのチューブによって保護している。通常、この保護チューブ内に光ファイバーを挿入する作業は、手作業で行うか、固定された保護チューブに対し光ファイバーを2つの回転する搬送ローラー間に挟んで送り込む方法が採られていた。また、流体の引きずり力を用いてケーブルをチューブ内に挿入する方法もあるが、双方のクリアランスの点から、その方法の転用は不可能である(例えば、特許文献1参照)。
特許第3138771号明細書
The optical fiber for communication has poor flexibility, and scratches and dirt on the outer periphery deteriorate the performance of the optical fiber. Therefore, the outer periphery is protected by a plastic tube having a length of about 1 m. Usually, the operation of inserting the optical fiber into the protective tube is performed manually, or the optical fiber is sandwiched between two rotating transport rollers and sent to the fixed protective tube. In addition, there is a method of inserting a cable into a tube by using a drag force of fluid, but the method cannot be diverted from the viewpoint of both clearances (see, for example, Patent Document 1).
Japanese Patent No. 3138771

しかしながら、上記従来の方法では、光ファイバーの外径と保護チューブの内径との寸法のバラツキ、湿度による抵抗、保護チューブの曲がり等が原因で、光ファイバーが保護チューブの途中で止まってしまい、チューブを交換したり、無理に押し込もうとして、保護チューブの入り口部分で光ファイバーが座屈して破損し、多量の損失を発生させるという問題があった。   However, in the above conventional method, the optical fiber stops in the middle of the protective tube due to variations in the outer diameter of the optical fiber and the inner diameter of the protective tube, resistance due to humidity, bending of the protective tube, etc. However, there was a problem that the optical fiber was buckled and damaged at the entrance of the protective tube, and a large amount of loss was generated.

したがって、本発明は、従来装置の有する上記の問題点に鑑みてなされたものであり、その目的は、光ファイバーを保護チューブ内にスムーズに挿入することができて、光ファイバーの破損による損失をなくすことのできる、この種挿入装置を提供することにある。   Therefore, the present invention has been made in view of the above-mentioned problems of the conventional apparatus, and the object thereof is to smoothly insert the optical fiber into the protective tube and to eliminate the loss due to the damage of the optical fiber. An object of the present invention is to provide this kind of insertion device.

上記目的を達成するため、本発明による光ファイバーを保護チューブに挿入する装置は、同心的に保護チューブを保持し得る円柱状の保護チューブホルダと、該保護チューブホルダを回転させる駆動手段と、光ファイバーを挟持して回転することにより該光ファイバーを回転中の前記保護チューブ内に送り込む一対の送りローラーとを備えている。   In order to achieve the above object, an apparatus for inserting an optical fiber according to the present invention includes a cylindrical protective tube holder that can concentrically hold a protective tube, a driving means that rotates the protective tube holder, and an optical fiber. A pair of feed rollers for feeding the optical fiber into the rotating protective tube by sandwiching and rotating.

また、本発明による光ファイバーを保護チューブに挿入する装置は、前記送りローラーの一方の端面に接触して駆動軸に取り付けられた摩擦板と、該摩擦板に対して前記送りローラーを所定の力で弾圧するスプリングとを更に備え、前記保護チューブ内に挿入中の光ファイバーに座屈力がかかったとき、前記送りローラーの回転が停止して前記摩擦板と前記駆動軸が空転するようになっている。   The apparatus for inserting an optical fiber according to the present invention into a protective tube comprises a friction plate attached to a drive shaft in contact with one end surface of the feed roller, and the feed roller with a predetermined force against the friction plate. A spring for pressing, and when a buckling force is applied to the optical fiber being inserted into the protective tube, the rotation of the feed roller is stopped and the friction plate and the drive shaft are idled. .

本発明によれば、前記駆動手段は、前記保護チューブホルダを上に載せて回転可能の一対のローラーを含んでいる。   According to the present invention, the driving means includes a pair of rollers that can rotate with the protective tube holder on top.

本発明にかかる光ファイバーの保護チューブへの挿入装置によれば、迅速に作業を行うことができるとともに、光ファイバーの破損による損失を確実に防止しすることができる。   According to the apparatus for inserting an optical fiber into a protective tube according to the present invention, it is possible to work quickly and to reliably prevent loss due to the damage of the optical fiber.

以下、本発明の実施の形態を図示した実施例に基き説明する。
図1は本発明装置の一実施例の平面図、図2は図1の正面図、図3は光ファイバー挿入部の正面図、図4は保護チューブ回転部の正面図、図5は保護チューブ内への光ファイバーの挿入状態を示す斜視図である。
Hereinafter, embodiments of the present invention will be described based on the illustrated examples.

It is a perspective view which shows the insertion state of the optical fiber to.

図中、1は内部に設けられたクランプ2によって保護チューブ3を同心的に保持し得る円柱状の保護チューブホルダ、4,4は保護チューブホルダ1を上に載せて回転させるため図示されていないモーターによって同一方向に回転される一対の回転ローラー、5は保護チューブ3に挿入される光ファイバー、6は図示されていないモーターによって回転される駆動軸、8はベアリング7を介して駆動軸6上に取り付けられた搬送ローラー、9は搬送ローラー8に対向配置されて搬送ローラー8との間に光ファイバー5を挟み得るピンチローラー、10は駆動軸6に取り付けられていて搬送ローラー8の端面に接触する摩擦板、11は搬送ローラー6の端面を摩擦板10に押圧する押さえスプリング、12は回転ローラー4,4にそれぞれ取り付けられたタイミングプーリー13,13に共通に掛けられたタイミングベルトである。このタイミングベルト12は、図示されていない駆動モーターの主軸に取り付けられた駆動プーリーにも掛けられている。14はピンチローラー9を搬送ローラー8に向けて弾圧するスプリングである。   In the figure, 1 is a cylindrical protective tube holder that can hold the protective tube 3 concentrically by a clamp 2 provided inside, and 4 and 4 are not shown in order to put the protective tube holder 1 on top and rotate it. A pair of rotating rollers rotated in the same direction by a motor, 5 an optical fiber inserted into the protective tube 3, 6 a drive shaft rotated by a motor (not shown), and 8 on the drive shaft 6 via a bearing 7. An attached conveyance roller, 9 is a pinch roller that is disposed opposite to the conveyance roller 8 and can sandwich the optical fiber 5 between the conveyance roller 8, and 10 is a friction that is attached to the drive shaft 6 and contacts the end surface of the conveyance roller 8 A plate, 11 is a pressing spring that presses the end surface of the transport roller 6 against the friction plate 10, and 12 is attached to each of the rotating rollers 4, 4. A timing belt that is wound in common to the timing pulley 13, 13 kicked. The timing belt 12 is also hung on a drive pulley attached to a main shaft of a drive motor (not shown). A spring 14 presses the pinch roller 9 toward the transport roller 8.

保護チューブホルダ1即ち回転ローラー4,4と搬送ローラー8とは、所定のタイミングで起動及び停止するように構成されている。また、押さえスプリング11は、保護チューブ3内に挿入中の光ファイバー5に座屈力がかかったとき、即ち、保護チューブ3と光ファイバー5の摩擦によって送りに抵抗が発生した場合は、搬送ローラー8が停止して駆動軸6と摩擦板10が空転するように、ばね定数が選定されている。   The protective tube holder 1, that is, the rotation rollers 4 and 4 and the transport roller 8 are configured to start and stop at a predetermined timing. Further, when the buckling force is applied to the optical fiber 5 being inserted into the protective tube 3, that is, when resistance is generated in the feed due to friction between the protective tube 3 and the optical fiber 5, the holding spring 11 is configured so that the transport roller 8 The spring constant is selected so that the drive shaft 6 and the friction plate 10 idle and stop.

以上のように構成されている本発明装置は、次のように作動する。
保護チューブ3を保護チューブホルダ1内のクランプ2によって固定し、回転ローラー4上にセットする。次に、光ファイバー5の先端を保護チューブ3に差し込み、搬送ローラー8とピンチローラー9の間に挟みこむ。続いて図示しないスイッチによって装置をスタートさせると、2本の回転ローラー4が同方向に廻り、保護チューブホルダ1を介して保護チューブ3が回転させられる。同時に駆動軸6が回転をはじめ、摩擦板10を介して搬送ローラー8をまわし、ピンチローラー9とともに光ファイバー5を保護チューブ3内に送り込む。この方法によって、光ファイバー5は推力と回転力の合成によってスムーズに保護チューブ3内を通過するようになる。また保護チューブ3の不良品があった場合は光ファイバー5に抵抗がかかり、搬送ローラー8と摩擦板10との間で滑りが発生し、光ファイバー5の破損を防止する。
The device of the present invention configured as described above operates as follows.
The protective tube 3 is fixed by the clamp 2 in the protective tube holder 1 and set on the rotating roller 4. Next, the tip of the optical fiber 5 is inserted into the protective tube 3 and sandwiched between the transport roller 8 and the pinch roller 9. Subsequently, when the apparatus is started by a switch (not shown), the two rotating rollers 4 rotate in the same direction, and the protective tube 3 is rotated through the protective tube holder 1. At the same time, the drive shaft 6 starts rotating, the conveying roller 8 is rotated via the friction plate 10, and the optical fiber 5 is fed into the protective tube 3 together with the pinch roller 9. By this method, the optical fiber 5 smoothly passes through the protective tube 3 by the combination of thrust and rotational force. Further, when there is a defective product of the protective tube 3, resistance is applied to the optical fiber 5, slippage occurs between the transport roller 8 and the friction plate 10, and the optical fiber 5 is prevented from being damaged.
