本発明は、絶縁電線、ケーブル（光ケーブルを含む）等の被覆長尺体において、絶縁体、編組シールド、外装（シース）、防食層等の被覆の断面形状が円形状ではなく、矩形、長円形等のような非円形状のものでも、その被覆を剥ぎ取るのに好適な被覆長尺体の被覆剥ぎ取り装置に関するものである。   In the present invention, in a covering long body such as an insulated wire or cable (including an optical cable), the cross section of the covering such as an insulator, a braided shield, an exterior (sheath), and an anticorrosion layer is not a circular shape, but a rectangle or an oval shape. The present invention also relates to a coating stripping device for a long coated body suitable for stripping the coating of a non-circular shape such as.

従来の被覆長尺体の被覆剥ぎ取り装置として、図１６に示す装置が提案されている。この装置は、基台（図示省略）に配設された、被覆長尺体Ａの被覆Ｂに環状切込みＣを形成するための環状切込形成ユニット１で構成される。その環状切込形成ユニット１は、被覆長尺体Ａと同軸状に配設される固定軸２と、固定軸２に回転自在に装着され、固定軸２を回転中心に回転駆動される回転支持体３と、切削刃５及び切削刃５を被覆長尺体Ａの軸線に垂直な方向に移動させる切削刃移動部６を有し、回転支持体３に装着されて固定軸２を回転中心に被覆長尺体Ａの外周を回転駆動され、被覆Ｂに切削刃５を切り込ませる切削刃切込手段４と、被覆長尺体Ａを把持する被覆長尺体クランプ７とを備える。   An apparatus shown in FIG. 16 has been proposed as a conventional covering stripping apparatus for strips. This apparatus is composed of an annular notch forming unit 1 for forming an annular notch C in a covering B of a covering long body A disposed on a base (not shown). The annular incision forming unit 1 includes a fixed shaft 2 coaxially arranged with the covering elongated body A, a rotation support that is rotatably mounted on the fixed shaft 2 and is driven to rotate about the fixed shaft 2. It has a cutting blade moving part 6 for moving the body 3, the cutting blade 5 and the cutting blade 5 in a direction perpendicular to the axis of the coated long body A, and is mounted on the rotary support 3 so that the fixed shaft 2 is the center of rotation. The outer periphery of the covering long body A is rotationally driven, and the cutting blade cutting means 4 for cutting the cutting blade 5 into the covering B and the covering long body clamp 7 for holding the covering long body A are provided.

前記切削刃切込手段４は２個有し、前記回転支持体３に１８０度対向するようにして配設されている。各切削刃切込手段４の切削刃移動部６は、回転支持体３の中心に向かって設置された支持レール８と、支持レール８に平行して設けられた移送ねじ９と、切削刃５を保持する切削刃ホルダ１０とを備え、切削刃ホルダ１０はこれに着設されたナット１１が移送ねじ９に螺合され、支持レール８に移動自在に嵌挿される。移送ねじ９は回転支持体３に装着されたサーボモータ等の駆動体１２の回転動力を、その回転軸１３に嵌着されたプーリ１４、プーリ１４に装架されたベルト１５を介してプーリ１６に伝動し、プーリ１６に結合された移送ねじ９を正逆回転させる。これにより、切削刃ホルダ１０を昇降させ、各切削刃切込手段４の切削刃５を接近又は離隔させ、被覆長尺体Ａの被覆Ｂに環状に切り込ませる深さが被覆Ｂの厚さ以下になるように調整する。なお、図１６において、１７は回転支持体３に同軸状に設けられた大歯車、１８はこれにかみ合う小歯車、１９は小歯車１８を回転させるロータリーアクチュエータであり、ロータリーアクチュエータ１９の駆動によって回転支持体３を正逆いずれかの方向に回転駆動させる（特許文献１参照）。   The cutting blade cutting means 4 has two pieces and is arranged so as to face the rotary support 3 180 degrees.

特開平８−２５１７４６号公報（発明の詳細な説明の項の段落番号００１１乃至００１６及び図１）JP-A-8-251746 (paragraph numbers 0011 to 0016 in FIG. 1 and FIG. 1)

従来の被覆剥ぎ取り装置は、その構造上、運転開始前に、切削刃切込手段４における切削刃移動部６の移送ねじ９を正逆回転させることにより、切削刃ホルダ１０を昇降させ、切削刃５を接近又は離隔させて、被覆長尺体Ａの被覆Ｂに所定深さの環状切込みが形成されるように、切削刃５の取り付け位置を調整するように構成されるものであり、運転中は切削刃の取付位置が予め調整された位置に固定される。   The conventional coating stripping device has a structure in which the cutting blade holder 10 is moved up and down by rotating the transfer screw 9 of the cutting blade moving part 6 in the cutting blade cutting means 4 in the forward and reverse directions before the operation is started. The blade 5 is moved close to or away from the cover B of the covering long body A so that an annular cut having a predetermined depth is formed in the cover B, and the mounting position of the cutting blade 5 is adjusted. Inside, the mounting position of the cutting blade is fixed at a position adjusted in advance.

そこで、被覆長尺体Ａの被覆Ｂの断面形状が円形状の場合には、切削刃５の刃先と被覆長尺体Ａの中心との距離が周方向の位置によって変位せず、被覆Ｂに切削刃５を全周にわたり所定深さに切り込ませてほぼ均等深さの環状切込みＣを形成することが可能になる。従って、被覆Ｂを軸方向に引き抜いて剥ぎ取ることが容易で、切込み不足による被覆Ｂの引きちぎりや切込み過剰による被覆内部の損傷を防止することができる。   Therefore, when the cross-sectional shape of the covering B of the covering long body A is circular, the distance between the cutting edge of the cutting blade 5 and the center of the covering long body A is not displaced depending on the position in the circumferential direction. The cutting blade 5 can be cut to a predetermined depth over the entire circumference to form an annular cut C having a substantially uniform depth. Therefore, it is easy to pull out and peel off the coating B in the axial direction, and it is possible to prevent the coating B from being torn off due to insufficient cutting or damage inside the coating due to excessive cutting.

しかしながら、被覆長尺体Ａが、例えば、図１７に示すように、２本の絶縁線心Ａ１を並列に配置して、これらの外周に一括してシースとなる被覆Ｂを設けた平型ケーブルのような場合には、被覆Ｂの断面形状が円形状ではなく、長円形状（非円形状）になっているので、環状切込みＣを形成するのが容易でない。即ち、このような被覆長尺体Ａの被覆Ｂに切削刃５を切り込ませて環状切込みＣを形成しようとすると、切削刃５の刃先と被覆長尺体Ａの中心との距離が周方向の位置によって変位する。従って、被覆Ｂに切削刃５を全周にわたり所定深さに切り込ませてほぼ均等深さの環状切込みＣを形成することが難しい。このため、被覆Ｂを軸方向に引き抜いて剥ぎ取ることが容易でなく、切込み不足による被覆Ｂの引きちぎりや切込み過剰による被覆内部の損傷を確実に防止することができないという問題がある。   However, as shown in FIG. 17, for example, the covering long body A is a flat cable in which two insulating wire cores A1 are arranged in parallel and a sheath B is collectively provided as a sheath on the outer periphery thereof. In such a case, since the cross-sectional shape of the coating B is not a circular shape but an oval shape (non-circular shape), it is not easy to form the annular cut C. That is, when the cutting blade 5 is cut into the coating B of such a covering long body A to form the annular cutting C, the distance between the cutting edge of the cutting blade 5 and the center of the covering long body A is the circumferential direction. It is displaced by the position of. Therefore, it is difficult to form the annular cut C having a substantially uniform depth by cutting the cutting blade 5 into the coating B at a predetermined depth over the entire circumference. For this reason, it is not easy to pull out and peel off the coating B in the axial direction, and there is a problem that it is impossible to reliably prevent the coating B from being torn off due to insufficient cutting or damage inside the coating due to excessive cutting.

本発明の目的は、被覆長尺体の被覆の断面形状が非円形状のものでも、被覆にほぼ均等深さの環状切込みを形成して被覆を容易に剥ぎ取ることができる被覆長尺体の被覆剥ぎ取り装置を提供することにある。   It is an object of the present invention to provide a long covering that can be easily peeled off by forming an annular cut having a substantially uniform depth in the covering even if the covering has a non-circular cross-sectional shape. It is to provide a coating stripping device.

The stopper member is provided so as to be movable in the longitudinal direction of the holding cylinder.

本発明の請求項３に記載された発明は、請求項１又は２記載の被覆長尺体の被覆剥ぎ取り装置において、前記基台に複数の環状切込形成ユニットが並列して配設され、両ユニットが共通のユニット駆動手段に連結されて相互に連動して駆動されることを特徴とするものである。 The invention described in claim 3 of the present invention is the covering stripping device for covering long body according to claim 1 or 2 , wherein a plurality of annular incision forming units are arranged in parallel on the base, Both units are connected to a common unit driving means and are driven in conjunction with each other.

本発明の請求項４に記載された発明は、請求項１、２又は３記載の被覆長尺体の被覆剥ぎ取り装置において、前記基台に切削刃切込手段における切削刃の刃先突出高さ調整具が配設され、その刃先突出高さ調整具が、ブロック状の刃先突出高さ調整具本体の上面に、切削刃ホルダにおける切削刃保持部分の外形状に合致する形状を有する切削刃ホルダ受面と、切削刃の刃先の外形状に合致する形状を有する切削刃受面とが隣接して配置され、切削刃受面が切削刃ホルダ受面よりも被覆長尺体の被覆に形成される環状切込みの深さ分低くなるように形成されることを特徴とするものである。 The invention described in claim 4 of the present invention is the coating stripping device for the coated elongated body according to claim 1, 2, or 3, wherein the cutting edge cutting height of the cutting blade in the cutting blade cutting means is provided on the base. An adjustment tool is provided, and the cutting edge height adjustment tool has a shape that matches the outer shape of the cutting blade holding portion of the cutting blade holder on the upper surface of the block-shaped cutting edge height adjustment tool body. The receiving surface and a cutting blade receiving surface having a shape that matches the outer shape of the cutting edge of the cutting blade are disposed adjacent to each other, and the cutting blade receiving surface is formed on the covering of the covering long body rather than the cutting blade holder receiving surface. It is characterized by being formed so as to be lower by the depth of the annular cut.

本発明の請求項１に記載された被覆剥ぎ取り装置によると、前記切削刃切込手段における切削刃移動部のホルダスペース内に、弾性部材を介して切削刃を保持する切削刃ホルダが被覆長尺体に対して進退移動し得るように支持されている。そこで、被覆の断面形状が非円形状である被覆長尺体の外周に切削刃を回転させながら、その被覆に切削刃を切り込ませて環状切込みを形成する際、切削刃の刃先と被覆長尺体の中心との距離が短くなる場合には、切削刃に作用する被覆からの切削抵抗が減少するので、弾性部材が伸長して切削刃ホルダが前進移動し、被覆に切込み不足が生じないように、切削刃を所定深さに切り込ませる。一方、切削刃の刃先と被覆長尺体の中心との距離が長くなる場合には、切削刃に作用する被覆からの切削抵抗が増大するので、弾性部材が縮んで切削刃ホルダが弾性部材の付勢に抗して後退移動し、被覆に切込み過剰が生じないように、同じ深さに切り込ませる。   According to the coating stripping apparatus described in claim 1 of the present invention, the cutting blade holder that holds the cutting blade via the elastic member is provided in the holder space of the cutting blade moving portion in the cutting blade cutting means. It is supported so that it can move forward and backward with respect to the scale. Therefore, when the cutting blade is rotated on the outer periphery of the long coating body having a non-circular cross-sectional shape and the annular cutting is formed by cutting the cutting blade into the coating, the cutting edge and the coating length When the distance from the center of the scale is shortened, the cutting resistance from the coating acting on the cutting blade is reduced, so that the elastic member is extended and the cutting blade holder is moved forward, so that the coating is not insufficiently cut. In this way, the cutting blade is cut to a predetermined depth. On the other hand, when the distance between the cutting edge of the cutting blade and the center of the long covering body increases, the cutting resistance from the covering acting on the cutting blade increases, so that the elastic member contracts and the cutting blade holder becomes elastic. Move backwards against the bias and cut to the same depth to avoid overcutting the coating.

従って、被覆に切削刃を全周にわたり所定深さに切り込ませてほぼ均等深さの環状切込みを形成することが可能になる。これにより、被覆を環状切込み部位から引き抜いて剥ぎ取ることが容易になり、切込み不足による被覆の引きちぎりや切込み過剰による被覆内部の損傷を確実に防止することができる。   Accordingly, it is possible to form an annular cut having a substantially uniform depth by cutting the cutting blade into the coating to a predetermined depth over the entire circumference. As a result, the coating can be easily pulled out and peeled off from the annular cut portion, and damage to the coating due to insufficient cutting or damage inside the coating due to excessive cutting can be reliably prevented.

更に、被覆長尺体の非円形状の被覆に切削刃を切り込む際、被覆の切削抵抗が増大して切削刃が後退し、弾性部材が縮むことにより切削刃の押付力が大きくなり、その刃先が被覆内に深く切り込もうとしても、切削刃保持部分が被覆の外面に当接し、刃先が設定された環状切込みの深さよりも深く切り込むのを規制される。Furthermore, when the cutting blade is cut into the non-circular coating of the long coated body, the cutting resistance of the coating is increased, the cutting blade is retracted, and the elastic member is contracted to increase the pressing force of the cutting blade. Even if it is going to cut deeply into the coating, the cutting blade holding portion comes into contact with the outer surface of the coating, and the cutting of the blade is restricted from being deeper than the annular cutting depth set.
よって、被覆長尺体の被覆に切込み過剰が生じるのをより確実に防止することができる。  Therefore, it is possible to more surely prevent excessive cutting from occurring in the covering of the covering long body.

本発明の請求項２記載の被覆剥ぎ取り装置によると、前記固定軸の切削刃切込手段側に、固定軸と同軸状に長尺体挿入穴を有する保持筒体が連結固定されているので、被覆長尺体の外周に切削刃を回転させながら、被覆に切削刃を切り込ませて環状切込みを形成する際、被覆長尺体の自由端側が保持筒体でしっかりと保持される。
従って、被覆長尺体の被覆に環状切込みを精度よく容易に形成することができる。また、保持筒体の長尺体挿入穴に、その穴に挿入された被覆長尺体の挿入長さを規制するストッパ部材が保持筒体の長手方向に移動可能に設けられるので、被覆に環状切込みを形成する位置のずれが減少し、所望長さの被覆を精度よく容易に剥ぎ取ることができる。 According to the coating stripping apparatus according to claim 2 of the present invention, the holding cylinder having the elongated body insertion hole coaxially with the fixed shaft is connected and fixed to the cutting blade cutting means side of the fixed shaft. When forming the annular cut by cutting the cutting blade into the coating while rotating the cutting blade around the outer periphery of the covering long body, the free end side of the covering long body is firmly held by the holding cylinder.
Therefore, an annular cut can be easily and accurately formed in the covering of the covering long body. In addition, a stopper member for restricting the insertion length of the covering long body inserted in the hole is provided in the long body insertion hole of the holding cylinder so as to be movable in the longitudinal direction of the holding cylinder. The shift of the position where the cut is formed is reduced, and the coating having a desired length can be easily and accurately peeled off.

本発明の請求項３記載の被覆剥ぎ取り装置によると、前記基台に複数の環状切込形成ユニットが並列して配設され、両ユニットが共通のユニット駆動手段に連結されて相互に連動して駆動されるので、複数本の被覆長尺体の被覆に同時に環状切込みを形成することができ、複数本の被覆長尺体の被覆を短時間に能率よく剥ぎ取ることができる。 According to the coating stripping device according to claim 3 of the present invention , a plurality of annular incision forming units are arranged in parallel on the base, and both units are connected to a common unit driving means and interlocked with each other. Therefore, an annular cut can be formed simultaneously in the covering of the plurality of covering long bodies, and the covering of the plurality of covering long bodies can be efficiently peeled off in a short time.

本発明の請求項４記載の被覆剥ぎ取り装置によると、前記基台に配設される切削刃の刃先突出高さ調整具が、切削刃ホルダにおける切削刃保持部分の外形状に合致する形状を有する切削刃ホルダ受面と、切削刃の刃先の外形状に合致する形状を有する切削刃受面とを有し、切削刃受面が切削刃ホルダ受面よりも被覆長尺体の被覆に形成される環状切込みの深さ分低くなるように構成される。
従って、切削刃の刃先の突出高さが被覆長尺体の被覆に形成される環状切込みの所定深さに合致するかどうかを簡単、且つ、迅速に確認することができ、環状切込みの切込み不足や切込み過剰による切込み不良を減少させることができる。 According to the coating stripping apparatus according to claim 4 of the present invention, the cutting edge protrusion height adjusting tool of the cutting blade disposed on the base has a shape that matches the outer shape of the cutting blade holding portion of the cutting blade holder. A cutting blade holder receiving surface, and a cutting blade receiving surface having a shape that matches the outer shape of the cutting edge of the cutting blade, and the cutting blade receiving surface is formed on the covering of the long covering body than the cutting blade holder receiving surface It is comprised so that it may become low by the depth of the cyclic | annular cut.
Therefore, it is possible to easily and quickly confirm whether or not the protruding height of the cutting edge of the cutting blade matches the predetermined depth of the annular cut formed in the covering of the long covering, and the annular cutting is insufficient. In addition, cutting defects due to excessive cutting can be reduced.

In the cutting blade holding portion 44b extending from the upper half to the upper half, a portion of the rectangular plate-shaped main body 44a that is slightly rearward from the center in the thickness direction is perpendicular to the lower part of the covering elongated body A and the axis of the covering elongated body A. A cutting blade holding groove 44c that is open on both sides is formed.

切削刃３８は円板状であり、その半径は切削刃３８が切削刃保持溝４４ｃに挿着されたとき、刃先が切削刃ホルダ４４の切削刃保持部分４４ｂの外面から被覆長尺体Ａの被覆Ｂに形成される環状切込みＣの深さに相当する高さ分、切削刃ホルダ４４の下半部の半円弧状径よりも大きな半径を有する。The cutting blade 38 is disk-shaped, and the radius of the cutting blade 38 is that the cutting edge of the covering long body A is formed from the outer surface of the cutting blade holding portion 44b of the cutting blade holder 44 when the cutting blade 38 is inserted into the cutting blade holding groove 44c. A radius corresponding to the depth corresponding to the depth of the annular cut C formed in the coating B is larger than the semicircular arc diameter of the lower half of the cutting blade holder 44.
切削刃３８は、切削刃保持溝４４ｃに、切削刃ホルダ４４の切削刃保持部分４４ｂの外面から刃先が環状切込みＣの深さに相当する高さ分だけ下方及び両側方に突出するようにして挿入され、止めねじ５２で締め付け固定される。なお、５４は止めねじ５２を螺着するねじ穴である。  The cutting blade 38 is configured so that the cutting edge protrudes downward and on both sides of the cutting blade holding groove 44c from the outer surface of the cutting blade holding portion 44b of the cutting blade holder 44 by a height corresponding to the depth of the annular cut C. Inserted and fixed with a set screw 52. Reference numeral 54 denotes a screw hole into which the set screw 52 is screwed.

前記切削刃３８の刃先が切削刃ホルダ４４の切削刃保持部分４４ｂの外面から被覆長尺体Ａの被覆Ｂに形成される環状切込みＣの深さに相当する高さ分、少なくとも被覆長尺体Ａが在る側に突出するように構成されると、被覆長尺体Ａの非円形状の被覆Ｂに切削刃３８を切り込む際、被覆Ｂの切削抵抗が増大して切削刃３８が後退し、弾性部材４８が縮むことにより切削刃３８の押付力が大きくなり、その刃先が被覆Ｂ内に深く切り込もうとしても、切削刃保持部分４４ｂが被覆Ｂの外面に当接し、刃先が設定された環状切込みＣの深さよりも深く切り込むのを規制される。
よって、被覆長尺体Ａの被覆Ｂに切込み過剰が生じるのをより確 実に防止することができる。 The blade edge of the cutting blade 38 is at least as long as the length corresponding to the depth of the annular cut C formed in the coating B of the coated long body A from the outer surface of the cutting blade holding portion 44b of the cutting blade holder 44. If the cutting blade 38 is cut into the non-circular coating B of the long covering A, the cutting resistance of the coating B increases and the cutting blade 38 moves backward when configured to protrude to the side where A is present. When the elastic member 48 is contracted, the pressing force of the cutting blade 38 is increased, and even if the cutting edge tries to cut deeply into the coating B, the cutting blade holding portion 44b comes into contact with the outer surface of the coating B, and the cutting edge is set. It is restricted to cut deeper than the depth of the annular cut C.
Therefore, it is possible to more surely prevent excessive cutting from occurring in the coating B of the long coated body A.

Tighten at 52 and check the height of the blade again.

切削刃３８の刃先突出高さ調整具２８が前記したような切削刃ホルダ受面１１２ａと切削刃受面１１２ｂとを有し、切削刃受面１１２ｂが切削刃ホルダ受面１１２ａよりも被覆長尺体Ａの被覆Ｂに形成される環状切込みＣの深さ分低くなるように構成されていると、切削刃３８の刃先の突出高さが被覆長尺体Ａの被覆Ｂに形成される環状切込みＣの所定深さに合致するかどうかを簡単、且つ、迅速に確認することができ、環状切込みＣの切込み不足や切込み過剰による切込み不良を減少させることができるので好ましい。なお、図１、２において、１１４は基台２０の長手方向の両端部近傍に取り付けられたコ字型の把手である。本実施形態の被覆剥ぎ取り装置は以上のような構成になっている。   The blade tip protrusion height adjusting tool 28 of the cutting blade 38 has the cutting blade holder receiving surface 112a and the cutting blade receiving surface 112b as described above, and the cutting blade receiving surface 112b is longer than the cutting blade holder receiving surface 112a. If the depth of the annular cut C formed in the coating B of the body A is lowered, the protruding height of the cutting edge of the cutting blade 38 is formed in the coating B of the coated long body A. It is preferable because it is possible to easily and quickly confirm whether or not it matches the predetermined depth of C, and it is possible to reduce cutting defects due to insufficient cutting or excessive cutting of the annular cutting C. In FIGS. 1 and 2, reference numeral 114 denotes a U-shaped handle attached in the vicinity of both ends in the longitudinal direction of the base 20. The coating stripping apparatus according to the present embodiment is configured as described above.

次に、本実施形態の装置を使用して、同一形状、構造、サイズの２本の被覆長尺体Ａ、例えば、平型ケーブル（図１７参照）の被覆Ｂに環状切込みＣを形成する方法を説明する。先ず、図１３、１４に示すように、保持筒体６２に設けられたストッパ部材６４を保持筒体６２の長尺体挿入穴６２ａ内を移動させ、切削刃３８から被覆長尺体Ａの被覆Ｂの所定剥ぎ取り長さだけ被覆長尺体Ａの進行方向に離隔した位置で蝶ねじ６６により締め付け固定し、ストッパ部材６４の位置を設定する。   Next, using the apparatus of the present embodiment, a method of forming an annular cut C in two covering elongated bodies A having the same shape, structure and size, for example, covering B of a flat cable (see FIG. 17) Will be explained. First, as shown in FIGS. 13 and 14, the stopper member 64 provided on the holding cylinder 62 is moved in the long body insertion hole 62 a of the holding cylinder 62, and the covering long body A is covered from the cutting blade 38. The position of the stopper member 64 is set by tightening and fixing with the thumbscrew 66 at a position separated in the traveling direction of the covering long body A by a predetermined stripping length of B.

次に、環状切込形成ユニット２２における被覆長尺体クランプ４２のレバー８８を手で引き上げて、クランプ片８０を弾性部材８２の付勢に抗して上昇させると共に、切削刃切込手段３６のレバー６０を引き上げて切削刃ホルダ４４を弾性部材４８の付勢に抗して上昇させる。   Next, the lever 88 of the covering long body clamp 42 in the annular incision forming unit 22 is pulled up by hand to raise the clamp piece 80 against the bias of the elastic member 82, and the cutting blade cutting means 36. The lever 60 is pulled up to raise the cutting blade holder 44 against the bias of the elastic member 48.

次に、このような状態、即ち、クランプ片８０及び切削刃ホルダ４４を上昇させた状態で、被覆長尺体Ａを図１３の左側から被覆長尺体クランプ４２の挿通穴７４ｂ及び保持筒体６２の長尺体挿入穴６２ａに挿入し、被覆長尺体Ａの先端部が保持筒体６２に設けられたストッパ部材６４に当接した時点で被覆長尺体Ａの挿入を停止する。   Next, in such a state, that is, in a state where the clamp piece 80 and the cutting blade holder 44 are raised, the covering long body A is inserted from the left side of FIG. 13 into the insertion hole 74b of the covering long body clamp 42 and the holding cylinder. 62 is inserted into the elongated body insertion hole 62 a, and insertion of the coated elongated body A is stopped when the tip of the coated elongated body A comes into contact with the stopper member 64 provided on the holding cylinder 62.

次に、被覆長尺体クランプ４２のレバー８８を引き上げる力を緩め、弾性部材８２の付勢により、クランプ片８０を下降させ、被覆長尺体Ａに押し付けてこれを把持する。次いで、切削刃切込手段３６のレバー６０を引き上げる力を緩め、弾性部材４８の付勢により、切削刃ホルダ４４を下降させ、切削刃３８の刃先を被覆長尺体Ａの被覆Ｂの外面に押し付ける。   Next, the force of pulling up the lever 88 of the covering long body clamp 42 is loosened, and the clamp piece 80 is lowered by the urging of the elastic member 82 and is pressed against the covering long body A to grip it. Next, the force for pulling up the lever 60 of the cutting blade cutting means 36 is loosened, and the cutting blade holder 44 is lowered by the urging of the elastic member 48, so that the cutting edge of the cutting blade 38 is placed on the outer surface of the coating B of the coated long body A. Press.

次に、環状切込形成ユニット２４についても前記ユニット２２と同様な操作を行って、被覆長尺体クランプ４２により他の被覆長尺体Ａを把持すると共に、切削刃切込手段３６により切削刃３８の刃先を被覆長尺体Ａの被覆Ｂの外面に押し付ける。   Next, the same operation as that of the unit 22 is performed for the annular incision forming unit 24 so that the other covering long body A is gripped by the covering long body clamp 42 and the cutting blade cutting means 36 cuts the cutting blade. 38 blade edges are pressed against the outer surface of the covering B of the covering long body A.

次に、ユニット駆動手段２６のベルトプーリ９８のハンドル１１０（図１参照）を持って、ベルトプーリ９８を、例えば、図１の時計方向に１乃至複数回回転させる。この回転に伴い、タイミングベルト１０２を介して環状切込形成ユニット２２、２４の切削刃切込手段３６、３６を固定軸３０、３０を回転中心に図１３、１４の矢印Ｄ方向へ同期して１乃至複数回回転させ、２本の被覆長尺体Ａの被覆Ｂに切削刃３８、３８を切り込ませ、所定深さの環状切込みＣを形成する。なお、環状切込みＣの切込み深さは切削刃３８、３８が回転する度に徐々に増す。切削刃１回転当たりの切込み深さは、切削刃３８、３８の材質、刃先形状、押付力、被覆Ｂの材質、硬さ等によって変わるが、これを実験等により求めることができる。そこで、所定の環状切込みＣの切込み深さ（被覆Ｂの厚さ以下）に対する切削刃３８、３８の所要回転数を容易に知ることができる。   Next, holding the handle 110 (see FIG. 1) of the belt pulley 98 of the unit driving means 26, the belt pulley 98 is rotated, for example, one or more times clockwise in FIG. Along with this rotation, the cutting blade cutting means 36, 36 of the annular cutting forming units 22, 24 are synchronized via the timing belt 102 in the direction of the arrow D in FIGS. The cutting blades 38 and 38 are cut into the covering B of the two covering long bodies A by rotating one or more times to form an annular notch C having a predetermined depth. The cutting depth of the annular cutting C gradually increases every time the cutting blades 38 and 38 rotate. The cutting depth per rotation of the cutting blade varies depending on the material of the cutting blades 38, 38, the shape of the cutting edge, the pressing force, the material of the coating B, the hardness, etc., and this can be obtained by experiments or the like. Therefore, the required number of rotations of the cutting blades 38 and 38 with respect to the predetermined cutting depth of the annular cutting C (below the thickness of the coating B) can be easily known.

次に、２本の被覆長尺体Ａの被覆Ｂに所要の環状切込みＣを形成した後、ユニット駆動手段２６の駆動を停止する。次いで、環状切込形成ユニット２２における被覆長尺体クランプ４２のレバー８８を引き上げ、クランプ片８０を上昇させて、被覆長尺体Ａの把持を解放すると共に、切削刃切込手段３６のレバー６０を引き上げて切削刃ホルダ４４を上方の非作業位置に退避させ、環状切込みＣが形成された被覆長尺体Ａを環状切込形成ユニット２２から引き抜く。これと同様な操作を環状切込形成ユニット２４についても行う。   Next, after the required annular cut C is formed in the covering B of the two covering long bodies A, the driving of the unit driving means 26 is stopped. Next, the lever 88 of the covering long body clamp 42 in the annular incision forming unit 22 is pulled up, the clamp piece 80 is lifted to release the covering long body A, and the lever 60 of the cutting blade cutting means 36 is used. Then, the cutting blade holder 44 is retracted to the upper non-working position, and the covering long body A in which the annular cut C is formed is pulled out from the annular cut forming unit 22. A similar operation is performed on the annular cut forming unit 24.

次に、一方の環状切込みＣが形成された被覆長尺体Ａについて、環状切込みＣから剥ぎ取られる側（自由端側）の被覆Ｂを手動、ペンチ等の治具で軸線方向に引き抜いて剥ぎ取る。他方の環状切込みＣが形成された被覆長尺体Ａについても同様にして被覆Ｂを剥ぎ取る。被覆Ｂに環状切込みＣを形成する際、切削刃切込手段３６（切削刃３８）を図１３、１４の矢印Ｄ方向に回転させたが、これと逆方向に回転させたり、矢印Ｄ方向とその逆方向に交互に回転させたりしてもよい。   Next, with respect to the covering long body A in which one annular cut C is formed, the covering B on the side to be peeled off from the annular cut C (free end side) is pulled out in the axial direction with a jig such as a manual or pliers and peeled off. take. The covering B is peeled off in the same manner with respect to the covering long body A in which the other annular cut C is formed. When the annular cut C is formed in the coating B, the cutting blade cutting means 36 (cutting blade 38) is rotated in the direction of arrow D in FIGS. It may be rotated alternately in the opposite direction.

なお、本実施形態では、環状切込形成ユニット２２、２４の被覆長尺体クランプ４２と切削刃切込手段３６に被覆長尺体Ａを挿入する際、被覆長尺体クランプ４２のクランプ片８０を上方の把持解放位置に、また、切削刃切込手段３６の切削刃ホルダ４４を上方の作業位置に上昇させるようにしたが、常時は、クランプ片８０及び切削刃ホルダ４４を上方の把持解放位置と非作業位置に保持させておき、被覆長尺体Ａの被覆Ｂに環状切込みＣを形成するために、環状切込形成ユニット２２、２４に被覆長尺体Ａを挿入した後、被覆長尺体クランプ４２のクランプ片８０及び切削刃切込手段３６の切削刃ホルダ４４を下方の把持位置と作業位置まで下降させるようにしてもよい。このようにすると、被覆長尺体Ａの挿入作業に手間がかからず楽になり、環状切込みＣを形成する作業能率が向上するので好ましい。   In the present embodiment, when the covering long body A is inserted into the covering long body clamp 42 and the cutting blade cutting means 36 of the annular incision forming units 22 and 24, the clamp piece 80 of the covering long body clamp 42 is used. Is raised to the upper grip release position, and the cutting blade holder 44 of the cutting blade cutting means 36 is raised to the upper working position. However, the clamp piece 80 and the cutting blade holder 44 are always held upward and released. In order to form the annular cut C in the covering B of the covering long body A by holding it in the position and the non-working position, after inserting the covering long body A into the annular cutting forming units 22 and 24, the covering length The clamp piece 80 of the scale clamp 42 and the cutting blade holder 44 of the cutting blade cutting means 36 may be lowered to the lower gripping position and working position. This is preferable because it takes less time and effort to insert the coated elongated body A and the work efficiency of forming the annular cut C is improved.

クランプ片８０と切削刃ホルダ４４を上方の前記位置に保持する手段としては、例えば、図１５（ａ）、（ｂ）に示すような構成になっている。即ち、被覆長尺体クランプ４２のクランプ片位置切替ロッド８４と切削刃切込手段３６のホルダ位置切替ロッド５０にこれらロッド８４、５０を貫通して係止ピン１１６を両側から突設させ、被覆長尺体クランプ４２のクランプフレーム７８の底部７８ｂ（頭部）上、及び、切削刃切込手段３６のホルダフレーム４６の底部４６ｃ（頭部）上に、周方向に１８０度対向配置して形成される一対の縦長の係止溝１１８ａ（図１５（ａ）（ｂ）では裏側に形成される係止溝１１８ａが省略されている）を有する環状のピン係止体１１８を設けて構成される。   As means for holding the clamp piece 80 and the cutting blade holder 44 in the above position, for example, a configuration as shown in FIGS. In other words, the clamp pin position switching rod 84 of the covering long body clamp 42 and the holder position switching rod 50 of the cutting blade cutting means 36 pass through these rods 84 and 50 so that the locking pins 116 protrude from both sides, Formed on the bottom portion 78b (head portion) of the clamp frame 78 of the long body clamp 42 and on the bottom portion 46c (head portion) of the holder frame 46 of the cutting blade cutting means 36 so as to face each other by 180 degrees in the circumferential direction. Provided with an annular pin locking body 118 having a pair of vertically long locking grooves 118a (the locking grooves 118a formed on the back side are omitted in FIGS. 15A and 15B). .

そして、常時は、クランプ片位置切替ロッド８４（クランプ片８０）及びホルダ位置切替ロッド５０（切削刃ホルダ４４）を上方の把持解放位置と非作業位置まで上昇させて、図１５（ａ）に示すように、これらロッド８４、５０を係止ピン１１６がピン係止体１１８の係止溝１１８ａから外れる位置、例えば、９０度外れるようにいずれか一方向に回動させ、ピン係止体１１８の上面に係止ピン１１６を係止させることにより保持する。   Then, normally, the clamp piece position switching rod 84 (clamp piece 80) and the holder position switching rod 50 (cutting blade holder 44) are raised to the upper grip release position and the non-working position, as shown in FIG. Thus, the rods 84 and 50 are rotated in any one direction so that the locking pin 116 is disengaged from the locking groove 118a of the pin locking body 118, for example, 90 degrees, so that the pin locking body 118 The locking pin 116 is held on the upper surface by being locked.

クランプ片位置切替ロッド８４とホルダ位置切替ロッド５０を下降させる場合には、これらロッド８４、５０を、図１５（ｂ）に示すように、係止ピン１１６が係止溝１１８ａの上部開口に合致するように、一方向又は他方向に更に回動させて、係止ピン１１６による係止を解除すればよい。
これにより、これらロッド８４、５０が弾性部材８２、４８により下方に引っ張られて下降する。一方、係止ピン１１６も係止溝１１８ａに沿って下降する。そして、係止ピン１１６が係止溝１１８ａの底部に到達して係止されたとき、これらロッド８４（クランプ片８０）、５０（切削刃ホルダ４４）が下方の把持位置、作業位置まで下降して停止する。なお、クランプ片位置切替ロッド８４とホルダ位置切替ロッド５０を回動させたとき、クランプ片８０、切削刃ホルダ４４が一緒に回動しないように、これらロッド８４、５０をクランプ片８０、切削刃ホルダ４４に回転自在に支持することが望ましい。 When lowering the clamp piece position switching rod 84 and the holder position switching rod 50, as shown in FIG. 15 (b), the locking pin 116 matches the upper opening of the locking groove 118a. In this manner, the locking by the locking pin 116 may be released by further rotating in one direction or the other direction.
As a result, the rods 84 and 50 are pulled downward by the elastic members 82 and 48 and lowered. On the other hand, the locking pin 116 also descends along the locking groove 118a. When the locking pin 116 reaches the bottom of the locking groove 118a and is locked, the rods 84 (clamp pieces 80) and 50 (the cutting blade holder 44) are lowered to the lower gripping position and working position. And stop. In addition, when the clamp piece position switching rod 84 and the holder position switching rod 50 are rotated, the clamp piece 80 and the cutting blade are arranged so that the clamp piece 80 and the cutting blade holder 44 do not rotate together. It is desirable to support the holder 44 rotatably.

本発明の被覆剥ぎ取り装置は、上記実施形態の装置から明らかなように、前記切削刃切込手段３６における切削刃移動部４０のホルダスペース４６ａ内に、弾性部材４８を介して切削刃３８を保持する切削刃ホルダ４４が被覆長尺体Ａに対して進退移動し得るように支持されている。
そこで、被覆Ｂの断面形状が非円形状である被覆長尺体Ａの外周に切削刃３８を回転させながら、その被覆Ｂに切削刃３８を切り込ませて環状切込みＣを形成する際、切削刃３８の刃先と被覆長尺体Ａの中心との距離が短くなる場合には、切削刃３８に作用する被覆Ｂからの切削抵抗が減少するので、弾性部材４８が伸長して切削刃ホルダ４４が前進移動し、被覆Ｂに切込み不足が生じないように、切削刃３８を所定深さに切り込ませる。一方、切削刃３８の刃先と被覆長尺体Ａの中心との距離が長くなる場合には、切削刃３８に作用する被覆Ｂからの切削抵抗が増大するので、弾性部材４８が縮んで切削刃ホルダ４４が弾性部材４８の付勢に抗して後退移動し、被覆Ｂに切込み過剰が生じないように、同じ深さに切り込ませる。 As is clear from the apparatus of the above embodiment, the coating stripping device of the present invention places the cutting blade 38 in the holder space 46a of the cutting blade moving portion 40 in the cutting blade cutting means 36 via the elastic member 48. The cutting blade holder 44 to be held is supported so as to be able to move forward and backward with respect to the covering long body A.
Accordingly, when the cutting blade 38 is rotated around the outer periphery of the covering long body A having a non-circular cross-sectional shape, the cutting blade 38 is cut into the covering B to form an annular cut C. When the distance between the blade tip of the blade 38 and the center of the covering long body A is shortened, the cutting resistance from the covering B acting on the cutting blade 38 is reduced, so that the elastic member 48 is extended and the cutting blade holder 44 is extended. Is moved forward, and the cutting blade 38 is cut to a predetermined depth so that the coating B is not cut short. On the other hand, when the distance between the cutting edge of the cutting blade 38 and the center of the covering long body A is increased, the cutting resistance from the covering B acting on the cutting blade 38 increases, so that the elastic member 48 is contracted and the cutting blade is contracted. The holder 44 moves backward against the urging force of the elastic member 48 so that the cover B is cut to the same depth so as not to cut excessively.

従って、被覆Ｂに切削刃３８を全周にわたり所定深さに切り込ませてほぼ均等深さの環状切込みＣを形成することが可能になる。これにより、被覆Ｂを環状切込みＣ部位から引き抜いて剥ぎ取ることが容易になり、切込み不足による被覆Ｂの引きちぎりや切込み過剰による被覆Ｂ内部の損傷を確実に防止することができる。   Therefore, the cutting blade 38 can be cut into the coating B at a predetermined depth over the entire circumference to form an annular cut C having a substantially uniform depth. Thereby, it becomes easy to pull out and peel off the coating B from the annular cut C region, and it is possible to reliably prevent the coating B from being torn off due to insufficient cutting or damage inside the coating B due to excessive cutting.
