Description

本発明は、被覆電線の被覆剥ぎ取り装置に関する。   The present invention relates to a device for stripping a covered electric wire.

従来、被覆電線の被覆を剥ぎ取る被覆剥ぎ取り装置が知られている（例えば、特許文献１参照）。特許文献１の被覆電線の被覆剥ぎ取り装置は、被覆電線の被覆の剥ぎ取り部分を剥ぎ取る際に、剥ぎ取り部分の両端に輪郭形状の刃により環状スリットを形成すると共に、剥ぎ取り部分に直線刃により直線スリットを形成して、剥ぎ取り部分を両端側から中央側に寄せることで、剥ぎ取り部分を被覆電線から除去するように構成されている。   2. Description of the Related Art Conventionally, a coating stripping device that strips a coating of a coated electric wire is known (for example, see Patent Document 1). The device for stripping a covered electric wire disclosed in Patent Document 1 forms an annular slit at both ends of the stripped portion with a contoured blade at the time of peeling off the stripped portion of the coating of the covered electric wire, and forms a straight line in the stripped portion. A straight slit is formed by a blade, and the stripped portion is removed from the covered electric wire by moving the stripped portion from both ends to the center.

特開２００７−１６６８７１号公報JP 2007-166871 A

特許文献１に記載の被覆電線の被覆剥ぎ取り装置においては、環状スリットや直線状スリットの切り込みを刃を用いて形成するため、芯線に傷を付ける可能性があった。また、被覆部分を両端から中央に寄せて被覆を芯線から除去しても、環状スリット及び直線スリットの形成時に被覆が芯線に食い込んでしまい、被覆が芯線に残存することがあった。一方で、芯線に食い込んだ被覆を強い力で除去すると、芯線への負荷が増加し、解れ（ほつれ）や損傷が生じやすくなる。そのため、芯線への負荷を低減しつつ、被覆を容易に剥ぎ取ることが望まれる。   In the stripping apparatus for a covered electric wire described in Patent Literature 1, since the slit of the annular slit or the linear slit is formed using the blade, there is a possibility that the core wire may be damaged. Further, even when the covering portion is moved to the center from both ends and the covering is removed from the core wire, the coating bites into the core wire when the annular slit and the linear slit are formed, and the coating sometimes remains on the core wire. On the other hand, if the coating that has penetrated the core wire is removed with a strong force, the load on the core wire increases, and loosening (fraying) and damage are likely to occur. Therefore, it is desired that the coating be easily peeled off while reducing the load on the core wire.

本発明は、芯線の解れや損傷を抑制できると共に、被覆が芯線に残存することを抑制でき、被覆電線から被覆を容易に剥ぎ取ることができる被覆電線の被覆剥ぎ取り装置を提供することを目的とする。   An object of the present invention is to provide a stripping apparatus for a covered electric wire, which can suppress the loosening and damage of the core wire, can suppress the coating from remaining on the core wire, and can easily peel off the coating from the coated electric wire. And

以下、本発明の一実施形態における被覆電線１０の被覆剥ぎ取り装置１について、図面を参照しながら説明する。図１は、本発明の一実施形態における被覆電線１０の被覆剥ぎ取り装置１の構成を示す斜視図である。図２は、被覆電線１０の被覆剥ぎ取り装置１を側方から視た図である。図３は、被覆電線１０の被覆剥ぎ取り装置１を上方から視た図である。   Hereinafter, an apparatus 1 for stripping a coated electric wire 10 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a device 1 for stripping a coated electric wire 10 according to an embodiment of the present invention. FIG. 2 is a diagram of the stripping device 1 for the coated electric wire 10 as viewed from the side. FIG. 3 is a diagram of the coating stripping device 1 for the coated electric wire 10 as viewed from above.

図１〜図３に示すように、本実施形態の被覆電線１０の被覆剥ぎ取り装置１は、被覆電線１０から被覆１１を剥ぎ取る装置である。
なお、本実施形態においては、第１アーム部４及び第２アーム部６が離間する方向をＸ方向といい、Ｘ方向における第１アーム部４が配置される側をＸ１側といい、Ｘ方向における第２アーム部６が配置される側をＸ２側という。Ｘ方向は、被覆剥ぎ取り装置１にセットされた被覆電線１０の径方向に一致する。被覆剥ぎ取り装置１にセットされた場合の被覆電線１０の軸方向をＹ方向という。Ｙ方向は、Ｘ方向に直交する。また、Ｘ方向及びＹ方向に直交する鉛直方向をＺ方向という。 As shown in FIGS. 1 to 3, a sheath stripping device 1 for a sheathed wire 10 of the present embodiment is a device for stripping a sheath 11 from a sheathed wire 10.
In the present embodiment, a direction in which the first arm unit 4 and the second arm unit 6 are separated from each other is referred to as an X direction, and a side in which the first arm unit 4 is disposed in the X direction is referred to as an X1 side. The side on which the second arm portion 6 is arranged is referred to as the X2 side. The X direction coincides with the radial direction of the insulated wire 10 set in the stripping device 1. The axial direction of the covered electric wire 10 when set on the covering stripping device 1 is referred to as a Y direction. The Y direction is orthogonal to the X direction. A vertical direction orthogonal to the X direction and the Y direction is called a Z direction.

被覆電線１０は、図１に示すように、被覆剥ぎ取り装置１にセットされる。被覆電線１０は、被覆剥ぎ取り装置１にセットされた場合に、Ｙ方向に延びて配置される。被覆電線１０は、図２に示すように、それぞれ、径方向の内部側に配置される芯線１２と、径方向の外部側において芯線１２を周方向に覆って配置される被覆１１と、を有する。本実施形態においては、例えば、芯線１２は、銅の材料で形成された複数の線材を撚ることで構成された撚り線である。被覆１１は、芯線１２の外面を被覆する。なお、芯線１２は、撚り線に限定されず、例えば、単線でもよい。   The covered electric wire 10 is set in the covering stripping device 1 as shown in FIG. When the insulated wire 10 is set in the stripping device 1, the insulated wire 10 extends in the Y direction. As shown in FIG. 2, each of the covered electric wires 10 has a core wire 12 arranged on the radially inner side, and a covering 11 arranged on the radially outer side so as to cover the core wire 12 in the circumferential direction. . In the present embodiment, for example, the core wire 12 is a stranded wire formed by twisting a plurality of wires formed of a copper material. The coating 11 covers the outer surface of the core wire 12. The core wire 12 is not limited to a stranded wire, and may be, for example, a single wire.

被覆電線１０には、図１に示すように、２つの環状スリット１１１と、１つの直線状スリット１１２と、が予め形成されている。
２つの環状スリット１１１は、被覆電線１０の軸方向に離間して形成され、被覆１１における剥ぎ取り部分１１０の両端に配置された環状の切り込みである。環状スリット１１１は、被覆電線１０の外周面において周方向の全域に亘って形成される。
１つの直線状スリット１１２は、被覆１１における剥ぎ取り部分１１０に形成された直線状の切り込みである。１つの直線状スリット１１２は、２つの環状スリット１１１の間において、被覆電線１０の軸方向に延びる直線状に形成される。本実施形態においては、１つの直線状スリット１１２は、２つの環状スリット１１１の間に亘って形成される。また、１つの直線状スリット１１２は、被覆電線１０の被覆剥ぎ取り装置１にセットされた状態において、被覆電線１０のＸ１側を向くように配置される。 As shown in FIG. 1, two annular slits 111 and one linear slit 112 are formed in the insulated wire 10 in advance.
The two annular slits 111 are annular cuts which are formed at a distance in the axial direction of the insulated wire 10 and are arranged at both ends of the stripped portion 110 of the insulated wire 11. The annular slit 111 is formed on the entire outer circumferential surface of the insulated wire 10 in the circumferential direction.
One linear slit 112 is a linear cut formed in the stripped portion 110 of the coating 11. One linear slit 112 is formed in a linear shape extending in the axial direction of the covered electric wire 10 between the two annular slits 111. In the present embodiment, one linear slit 112 is formed between two annular slits 111. In addition, one linear slit 112 is arranged so as to face the X1 side of the insulated wire 10 when set in the stripping device 1 for the insulated wire 10.

２つの環状スリット１１１及び１つの直線状スリット１１２は、本実施形態の被覆電線１０の被覆剥ぎ取り装置１にセットされる前に、例えば、レーザ加工により予め形成される。例えば、レーザ加工により環状スリット１１１及び直線状スリット１１２を形成する場合には、レーザ光によりスリットを形成するため、芯線１２に傷を付けることなく、被覆１１のみに切り込みを入れることができる。なお、２つの環状スリット１１１及び１つの直線状スリット１１２の形成方法は、レーザ加工に限定されない。また、被覆電線１０に予め形成する切り込みの形状は、前記環状スリット１１１や前記直線状スリット１１２のスリットの切り込みに代えて、ミシン目の切り込みでもよい。   The two annular slits 111 and one linear slit 112 are formed in advance by, for example, laser processing before being set in the stripping apparatus 1 for the coated electric wire 10 of the present embodiment. For example, when the annular slit 111 and the linear slit 112 are formed by laser processing, since the slit is formed by laser light, a cut can be made only in the coating 11 without damaging the core wire 12. Note that the method of forming the two annular slits 111 and one linear slit 112 is not limited to laser processing. Further, the shape of the cut formed in advance on the covered electric wire 10 may be a perforated cut instead of the cut of the slit of the annular slit 111 or the linear slit 112.

The pair of first claws 41, 41 protrude toward the insulated wire 10 at the tip of the first arm 4, and extend inward in the axial direction of the insulated wire 10 so as to approach each other.

第１爪部４１は、図２に示すように、被覆電線１０の軸方向に幅を有する対向円弧面４１１（円弧面）を有し、第１爪部４１の対向円弧面４１１の曲率半径（アール）は、被覆電線１０の外周面の曲率半径（アール）よりも曲がりが緩やかな曲率である。これにより、一対の第１アーム部４，４と一対の第２アーム部６，６（後述）との間に被覆電線１０を挟み込む際に、一対の第１アーム部４，４の対向円弧面４１１は、被覆電線１０を締め付けることが抑制された状態で挟み込むことができる。よって、第１爪部４１は、被覆電線１０を変形させることが抑制された状態で、即ち芯線１２への負荷を低減した状態で、Ｘ１側から被覆電線１０を挟み込むことができる。   As shown in FIG. 2, the first claw portion 41 has an opposing arc surface 411 (arc surface) having a width in the axial direction of the covered electric wire 10, and a radius of curvature of the opposing arc surface 411 of the first claw portion 41 ( (R) is a curvature whose bend is gentler than the radius of curvature (R) of the outer peripheral surface of the covered electric wire 10. Accordingly, when the insulated wire 10 is sandwiched between the pair of first arm portions 4 and 4 and the pair of second arm portions 6 and 6 (described later), the opposing arc surfaces of the pair of first arm portions 4 and 4 are used. 411 can be sandwiched in a state where tightening of the insulated wire 10 is suppressed. Therefore, the first claw portion 41 can sandwich the covered electric wire 10 from the X1 side in a state where the deformation of the covered electric wire 10 is suppressed, that is, in a state where the load on the core wire 12 is reduced.

Each of the plurality of grooves 411 a is formed to extend in an arc-shaped groove along the outer peripheral surface of the covered electric wire 10 on the facing circular arc surface 411, and extends in a direction intersecting the axial direction of the covered electric wire 10. The plurality of grooves 411a of the first claw 41 are caught on the surface of the covering 11 when the first claw 41 is moved in the axial direction of the covered electric wire 10, so that the stripped portion 110 of the covering 11 is moved to the core wire 12. Can be easily brought to the center or the end in a state where the load is reduced. In the present embodiment, the groove 411a is formed, for example, in a concave shape extending in an arc direction. The groove may be formed in, for example, a convex shape extending in an arc direction.

In the Y direction (the axial direction of the insulated wire 10), the pair of first arms 4 and 4 are moved to a side closer to each other (closed side) so as to move the taking part 110 from both ends to the center. In addition, control is performed such that the pair of second arm portions 6 and 6 are moved to a side closer to each other (closer side) (first control).

これにより、図４Ｃに示すように、一対の第１アーム部４，４及び一対の第２アーム部６，６は、それぞれ、Ｙ方向（被覆電線１０の軸方向）において、互いが近づく側（閉じる側）に移動される。よって、被覆１１の剥ぎ取り部分１１０は、環状スリット１１１において被覆１１から切断されて被覆電線１０が軸方向の中央側に寄せられる。この状態においては、被覆１１の剥ぎ取り部分１１０は、被覆電線１０の軸方向において、一対の第１アーム部４，４の第１爪部４１同士の間に挟み込まれ、かつ、一対の第２アーム部６，６の第２爪部６１同士の間に挟み込まれている。   Thereby, as shown in FIG. 4C, the pair of first arm portions 4 and 4 and the pair of second arm portions 6 and 6 are closer to each other in the Y direction (the axial direction of the covered electric wire 10) ( (Close side). Therefore, the stripped portion 110 of the coating 11 is cut from the coating 11 at the annular slit 111, and the coated electric wire 10 is moved toward the center in the axial direction. In this state, the stripped portion 110 of the covering 11 is sandwiched between the first claws 41 of the pair of first arms 4 and 4 in the axial direction of the covered electric wire 10, and The arm portions 6 and 6 are sandwiched between the second claw portions 61.

次に、制御部９は、一対の第２アーム部６，６を移動させない状態（被覆電線１０の軸方向において一対の第２アーム部６，６を互いが近づく側に位置させた状態）で、図４Ｃに示す状態から、剥ぎ取り部分１１０における直線状スリット１１２が形成された部分を中央部側から両端部側に寄せるように、Ｙ方向（被覆電線１０の軸方向）において、一対の第１アーム部４，４を互いが近づく側（閉じる側）に位置した状態から互いが離れる側（開く側）に移動させるように制御する（第２制御）。これにより、図４Ｄに示すように、被覆１１は、直線状スリット１１２が設けられた剥ぎ取り部分１１０において、中央部側に引き寄せられた状態から両端部側に引き延ばされる。その結果、直線状スリット１１２の切り込みの隙間が広がって、剥ぎ取り部分１１０を直線状スリット１１２の反対側から引っ張って引き剥がす際に、直線状スリット１１２の切り込みが開きやすくなる。   Next, the control unit 9 does not move the pair of second arms 6, 6 (a state in which the pair of second arms 6, 6 are positioned on the side closer to each other in the axial direction of the insulated wire 10). From the state shown in FIG. 4C, in the Y direction (the axial direction of the insulated wire 10), a pair of the first and second stripped portions in the stripped portion 110 are shifted from the center to the both ends. Control is performed so that the first arm units 4 and 4 are moved from a state where they are closer to each other (closed side) to a side where they are separated from each other (opening side) (second control). Thereby, as shown in FIG. 4D, the coating 11 is extended to both ends from the state of being pulled toward the center in the stripped portion 110 in which the linear slit 112 is provided. As a result, the cut gap of the linear slit 112 is widened, and the cut of the linear slit 112 is easily opened when the peeling portion 110 is pulled from the opposite side of the linear slit 112 and peeled off.

その後、図４Ｅに示すように、一対の第１アーム部４，４を被覆電線１０から離れる側（Ｘ１側）に移動させた後に、制御部９は、被覆電線１０の軸方向において一対の第２アーム部６，６が剥ぎ取り部分１１０を挟み込んだ状態（被覆電線１０の軸方向において一対の第２アーム部６，６を互いが近づく側に位置させた状態）で、Ｘ方向（被覆電線１０の軸方向に交差する径方向）において、一対の第２アーム部６，６を被覆電線１０から離れる側（Ｘ２側）に移動するように制御する（第３制御）。   Thereafter, as shown in FIG. 4E, after moving the pair of first arm portions 4 and 4 to the side (X1 side) away from the insulated wire 10, the controller 9 controls the pair of first arms 4 and 4 in the axial direction of the insulated wire 10. In a state where the two arms 6 and 6 sandwich the stripped portion 110 (a state where the pair of second arms 6 and 6 are located on the side closer to each other in the axial direction of the covered electric wire 10), in the X direction (the covered electric wire). In the radial direction intersecting with the axial direction of No. 10), the pair of second arm portions 6 and 6 are controlled to move to the side (X2 side) away from the insulated wire 10 (third control).

これにより、図４Ｆに示すように、一対の第２アーム部６，６をＸ２側に移動させることで、一対の第２アーム部６，６により挟まれた剥ぎ取り部分１１０をＸ２側に引っ張ることで、切り込みの隙間が広がった直線状スリット１１２を介して、被覆電線１０から被覆１１の剥ぎ取り部分１１０を剥ぎ取ることができる。このように、被覆電線１０から被覆１１の剥ぎ取り部分１１０を、容易に剥ぎ取ることができる。   Thereby, as shown in FIG. 4F, by moving the pair of second arms 6, 6 toward the X2 side, the stripped portion 110 sandwiched between the pair of second arms 6, 6 is pulled toward the X2 side. Thus, the stripped portion 110 of the coating 11 can be stripped from the coated electric wire 10 through the linear slit 112 in which the cut gap is widened. Thus, the stripped portion 110 of the coating 11 can be easily stripped from the coated electric wire 10.

その後、図４Ｇに示すように、制御部９は、Ｙ方向（被覆電線１０の軸方向）において、一対の第２アーム部６，６を互いが離れる側（開く側）に移動させる。これにより、被覆１１の剥ぎ取り部分１１０を落下させることができるため、剥ぎ取り部分１１０を回収することができる。   Thereafter, as illustrated in FIG. 4G, the control unit 9 moves the pair of second arm units 6, 6 to a side away from each other (open side) in the Y direction (the axial direction of the covered electric wire 10). Thereby, since the stripped portion 110 of the coating 11 can be dropped, the stripped portion 110 can be collected.

本発明における本実施形態の被覆電線１０の被覆剥ぎ取り装置１によれば、次のような効果が奏される。
（１）被覆電線１０の剥ぎ取り装置１は、被覆電線１０から被覆１１を剥ぎ取る被覆電線１０の被覆剥ぎ取り装置１であって、被覆電線１０には、２つの環状スリット１１１と１つの直線状スリット１１２と、が予め形成され、剥ぎ取り部分１１０を一対の第１アーム部４，４と一対の第２アーム部６，６とで被覆電線１０の径方向に挟んだ状態で、被覆電線１０の軸方向において、一対の第１アーム部４，４を互いが近づく側に移動させ、かつ、一対の第２アーム部６，６を互いが近づく側に移動させるように制御する第１制御を実行し、第１制御の実行後に、被覆電線１０の軸方向において一対の第２アーム部６，６を互いが近づく側に位置させた状態で、一対の第１アーム部４，４を互いが近づく側（閉じる側）に位置した状態から互いが離れる側（開く側）に移動させるように制御する第２制御を実行する制御部９と、を備える。そのため、剥ぎ取り部分１１０が直線状スリット１１２において中央部側に寄せられた後に、両端部側に引き延ばされることで、直線状スリット１１２の切り込みの隙間が広がって、剥ぎ取り部分１１０を直線状スリット１１２の反対側から引っ張って引き剥がす際に、直線状スリット１１２の切り込みが開きやすくなる。これにより、切り込みの隙間が広がった直線状スリット１１２を介して、被覆１１の剥ぎ取り部分１１０を、容易に剥ぎ取ることができる。よって、芯線１２の解れや損傷を抑制できると共に、被覆１１が芯線１２に残存することを抑制でき、被覆電線１０から被覆１１を容易に剥ぎ取ることができる。 According to the device 1 for stripping the coated electric wire 10 of the present embodiment of the present invention, the following effects can be obtained.
(1) The stripping device 1 for the insulated wire 10 is the stripping device 1 for the insulated wire 10 that strips the coating 11 from the insulated wire 10. The insulated wire 10 has two annular slits 111 and one straight line. Is formed in advance, and the stripped portion 110 is sandwiched between the pair of first arms 4 and 4 and the pair of second arms 6 and 6 in the radial direction of the covered electric wire 10. A first control for moving the pair of first arms 4 and 4 toward each other and moving the pair of second arms 6 and 6 toward each other in the axial direction of 10; Is performed, and after the first control is performed, the pair of first arms 4 and 4 are mutually moved in a state where the pair of second arms 6 and 6 are positioned on the side approaching each other in the axial direction of the insulated wire 10. Are closer to each other (closed side). And a control unit 9 for performing a second control to control to move to the side (open side) of leaves, a. Therefore, after the stripped portion 110 is moved to the center portion side in the linear slit 112 and then extended to both end portions, the gap of the cut of the linear slit 112 is widened, and the stripped portion 110 is formed in a straight line. When pulling from the opposite side of the slit 112 and peeling it off, the cut of the linear slit 112 is easily opened. Accordingly, the stripped portion 110 of the coating 11 can be easily peeled off through the linear slit 112 having a wide cut gap. Accordingly, the core wire 12 can be prevented from being loosened or damaged, and the coating 11 can be prevented from remaining on the core wire 12, and the coating 11 can be easily peeled off from the coated electric wire 10.

（２）制御部９は、第２制御の実行後に、被覆電線１０の軸方向において一対の第２アーム部６，６を互いが近づく側に位置させた状態で、一対の第２アーム部６，６を被覆電線１０から離れるように制御する第３制御を実行する。そのため、被覆電線１０から被覆１１の剥ぎ取り部分１１０を、容易に剥ぎ取ることができる。 (2) After executing the second control, the control unit 9 sets the pair of second arm units 6 and 6 in a state where the pair of second arm units 6 and 6 are located on the side closer to each other in the axial direction of the insulated wire 10. , 6 are controlled to move away from the insulated wire 10. Therefore, the stripped portion 110 of the coating 11 can be easily stripped from the coated electric wire 10.

（３）第１アーム部４，４の対向円弧面４１１の曲率は、被覆電線の外周面の曲率よりも曲がりが緩やかな曲率である。また、第２アーム部６，６の対向円弧面６１１の曲率は、被覆電線の外周面の曲率よりも曲がりが緩やかな曲率である。これにより、一対の第１アーム部４，４と一対の第２アーム部６，６との間に被覆電線１０を挟み込む際に、一対の第１アーム部４，４の対向円弧面４１１が、被覆電線１０を締め付けることが抑制されると共に、一対の第２アーム部６，６の対向円弧面６１１が、被覆電線１０を締め付けることが抑制される。よって、被覆電線１０を変形させることが抑制された状態で、即ち芯線１２への負荷を低減させた状態で、被覆電線１０を挟み込むことができる。 (3) The curvature of the opposing arc surfaces 411 of the first arm portions 4 and 4 is a curvature that is gentler than the curvature of the outer peripheral surface of the covered electric wire. Further, the curvature of the facing arc surface 611 of the second arm portions 6, 6 is a curvature that is gentler than the curvature of the outer peripheral surface of the covered electric wire. Accordingly, when the covered electric wire 10 is sandwiched between the pair of first arm portions 4 and 4 and the pair of second arm portions 6 and 6, the opposed arc surfaces 411 of the pair of first arm portions 4 and 4 Tightening of the insulated wire 10 is suppressed, and tightening of the insulated wire 10 by the opposing arc surfaces 611 of the pair of second arms 6, 6 is suppressed. Therefore, the covered electric wire 10 can be sandwiched in a state where the deformation of the covered electric wire 10 is suppressed, that is, in a state where the load on the core wire 12 is reduced.

（４）第１アーム部４，４の対向円弧面４１１には、被覆電線１０の軸方向に交差する方向に延びる複数の溝４１１ａが形成される。また、第２アーム部６，６の対向円弧面６１１には、被覆電線１０の軸方向に交差する方向に延びる複数の溝６１１ａが形成される。そのため、第１爪部４１の複数の溝４１１ａは、第１爪部４１を被覆電線１０の軸方向に移動させた場合に、被覆１１の表面に引っ掛かるため、被覆１１の剥ぎ取り部分１１０を中央部側又は端部側に容易に寄せることができる。 (4) A plurality of grooves 411a extending in a direction intersecting the axial direction of the covered electric wire 10 are formed in the opposed arcuate surfaces 411 of the first arm portions 4, 4. Further, a plurality of grooves 611a extending in a direction intersecting the axial direction of the covered electric wire 10 are formed in the opposed circular arc surfaces 611 of the second arm portions 6, 6. Therefore, the plurality of grooves 411a of the first claw portion 41 are caught on the surface of the coating 11 when the first claw portion 41 is moved in the axial direction of the coated electric wire 10, so that the stripped portion 110 of the coating 11 is centered. It can be easily moved to the part side or the end side.

以上、好適な実施形態について説明したが、本発明は前述した実施形態に限定されることなく種々の形態で実施することができる。   The preferred embodiment has been described above, but the present invention can be implemented in various forms without being limited to the above-described embodiment.

（アーム形状）
一対の第１アーム部４，４及び一対の第２アーム部６，６は、被覆電線１０の被覆剥ぎ取り装置１を上方（Ｚ軸方向）から視た場合の形状が、Ｌ字形状に限定されず、かつ、一対の第１アーム部４，４と第２アーム部６，６は、それぞれ非対称の形状でもよい。例えば、第２アーム部の形状を直線形状で構成してもよい。これにより、アーム形状を簡略化することができ、製造コストを低減することができる。なお、第１アーム部４，４と第２アーム部６，６の形状を逆に構成してもよい。 (Arm shape)
The pair of first arm portions 4 and 4 and the pair of second arm portions 6 and 6 are limited to L-shaped when viewed from above (in the Z-axis direction) of the stripping device 1 for the coated electric wire 10. However, the pair of the first arm portions 4 and 4 and the second arm portions 6 and 6 may have asymmetric shapes. For example, the shape of the second arm portion may be a linear shape. Thus, the shape of the arm can be simplified, and the manufacturing cost can be reduced. The shapes of the first arm portions 4 and 4 and the second arm portions 6 and 6 may be reversed.

（爪部の長さ）
第１爪部４１と第２爪部６１は、被覆電線１０を径方向に挟み込んだ場合に、互いに接触しない長さ、かつ、対向円弧面４１１，６１１の半径が被覆電線１０の半径よりも短く構成されていてもよい。これにより、爪部同士の接触による衝突破損を防止し、かつ、被覆電線１０を径方向に挟み込んだ場合に、第１爪部４１と第２爪部６１とが互いに接触しない程度の大きさの半径を有する被覆電線１０に対する剥ぎ取り動作を行うことが可能である。よって、第１アーム部４，４と第２アーム部６，６とを、それぞれの被覆電線１０の半径に応じて個別に製造する必要がなくなるため、第１アーム部４，４と第２アーム部６，６の製造コストや交換作業工数を削減することができる。 (Claw length)
The first claw portion 41 and the second claw portion 61 have a length that does not contact each other when the insulated wire 10 is sandwiched in the radial direction, and the radius of the opposing arc surfaces 411 and 611 is shorter than the radius of the insulated wire 10. It may be configured. Thereby, collision damage due to contact between the claws is prevented, and the first claw 41 and the second claw 61 are of such a size that they do not contact each other when the covered electric wire 10 is sandwiched in the radial direction. It is possible to perform a stripping operation on the insulated wire 10 having a radius. Therefore, it is not necessary to manufacture the first arm portions 4 and 4 and the second arm portions 6 and 6 individually according to the radius of each of the covered electric wires 10, so that the first arm portions 4 and 4 and the second arm portion 4 are not required. The manufacturing costs and replacement man-hours of the units 6 and 6 can be reduced.

（爪部形状）
また、第１爪部４１と第２爪部６１は、対向円弧面４１１，６１１を有して構成されているが、被覆電線１０の外周面に接する部分を有するように多角形状に構成してもよい。例えば、爪部同士が接した時に、Ｙ方向（被覆電線１０の軸方向）に視た場合の断面（Ｘ方向に切断した場合の断面）の形状が六角形となるように構成してもよい。これにより、爪部に円弧面を形成する場合と比較して、六角形の辺同士が鈍角で当接する角部に被覆電線を挟み込む際に、被覆電線１０の被覆１１が押し出される隙間が生じるため、第１爪部４１は、被覆電線１０を変形させることが抑制された状態で、即ち、芯線１２への負荷を低減した状態で、Ｘ１側から被覆電線１０を挟み込むことができる。 (Claw shape)
Further, the first claw portion 41 and the second claw portion 61 are configured to have the opposing circular arc surfaces 411 and 611, but are configured in a polygonal shape so as to have a portion in contact with the outer peripheral surface of the covered electric wire 10. Is also good. For example, when the claw portions come into contact with each other, the cross section when viewed in the Y direction (the axial direction of the covered electric wire 10) (the cross section when cut in the X direction) may be configured to be a hexagon. . Thereby, compared with the case where the arc surface is formed in the claw portion, when the covered wire is sandwiched in the corner where the sides of the hexagon abut at an obtuse angle, a gap is generated in which the covering 11 of the covered wire 10 is pushed out. The first claw portion 41 can sandwich the covered electric wire 10 from the X1 side in a state where the deformation of the covered electric wire 10 is suppressed, that is, in a state where the load on the core wire 12 is reduced.

（爪部の対向円弧面の溝）
また、第１爪部４１、第２爪部６１の対向円弧面４１１，６１１に設けられる溝４１１ａ，６１１ａは、被覆電線１０の外周面に沿った円弧状の溝状に延びて形成されるが、円弧方向に対して角度を有して、例えば、ローレット形状のように斜め状に形成されてもよい。更に、一対の第１アーム部４，４と第２アーム部６，６は、それぞれ移動方向または撚り線のねじれ方向に応じて非対称に形成されてもよい。これにより、第１アーム部４，４と第２アーム部６，６とをそれぞれＹ方向の中央部側に寄せる制御を行なう場合に、被覆１１を容易に剥ぎ取ることができる。 (Groove on the opposite arc surface of the claw)
Also, the grooves 411a and 611a provided on the opposing arc surfaces 411 and 611 of the first claw portion 41 and the second claw portion 61 are formed to extend in an arc-shaped groove shape along the outer peripheral surface of the covered electric wire 10. May be formed obliquely, for example, in a knurled shape, with an angle to the arc direction. Further, the pair of first arm portions 4, 4 and second arm portions 6, 6 may be formed asymmetrically in accordance with the moving direction or the twist direction of the stranded wire, respectively. Thereby, when controlling to bring the first arm portions 4 and 4 and the second arm portions 6 and 6 toward the center in the Y direction, the coating 11 can be easily peeled off.

（被覆電線から被覆を剥ぎ取る動作について）
制御部９における第１制御において、剥ぎ取り部分１１０を一対の第１アーム部４，４と一対の第２アーム部６，６とで径方向に挟んだ状態で、図４Ｂに示すように、剥ぎ取り部分１１０を両端部側から中央部側に寄せるように、Ｙ方向（被覆電線１０の軸方向）において、一対の第１アーム部４，４を互いが近づく側（閉じる側）に移動させ、かつ、一対の第２アーム部６，６を互いが近づく側（閉じる側）に移動させるように制御しているが、これに限定されず、一対の第１アーム部４，４と一対の第２アーム部６，６をそれぞれが閉じる側に移動させる際に、所定の時間差を設けて駆動させる制御を行なってもよい。これにより、被覆電線１０に設けられた環状スリット１１１のうち、一対の第１アーム部４，４側の被覆１１を先に剥ぎ取ることができ、被覆電線１０が引き延ばされるために、環状スリット１１１の切り込みと、直線状スリット１１２の切り込みが開きやすくなる。よって、被覆１１に食い込んだ芯線１２を取り除きやすくなり、被覆１１を容易に剥ぎ取ることができる。 (About the operation of stripping the sheath from the insulated wire)
In the first control by the control unit 9, in a state where the stripping portion 110 is radially sandwiched between the pair of first arm portions 4, 4 and the pair of second arm portions 6, 6, as shown in FIG. In the Y direction (axial direction of the insulated wire 10), the pair of first arms 4 and 4 are moved to a side closer to each other (closed side) so that the stripped portion 110 is moved from both ends to the center. Further, the pair of second arms 6 and 6 are controlled to be moved to a side closer to each other (closed side), but the present invention is not limited to this, and the pair of first arms 4 and 4 and the pair of second arms 6 and 6 are controlled. When each of the second arms 6 and 6 is moved to the closing side, a control for driving the second arms 6 and 6 with a predetermined time difference may be performed. Thereby, among the annular slits 111 provided in the insulated wire 10, the sheaths 11 on the pair of first arm portions 4 and 4 can be peeled off first, and the insulated wire 10 is extended, so that the annular slit 111 is extended. The cut of 111 and the cut of the linear slit 112 are easily opened. Therefore, the core wire 12 that has penetrated the coating 11 can be easily removed, and the coating 11 can be easily peeled off.

なお、所定の時間差とは、剥ぎ取り部分１１０を径方向に挟んだ状態において、一対の第１アーム部４，４のみが先に移動を開始した時間を０（ゼロ）として、第１爪部４１の有する幅と第２爪部６１の有する幅とが非重複状態になるまでの時間をｔとした場合に、０（ゼロ）からｔまでの間の任意の時間を時間差として設定したものである。   Note that the predetermined time difference is defined as a time at which only the pair of first arm portions 4 and 4 starts moving first in a state where the stripped portion 110 is sandwiched in the radial direction, and the first claw portion is defined as 0 (zero). An arbitrary time from 0 (zero) to t is set as a time difference, where t is the time until the width of the 41 and the width of the second claw 61 are in the non-overlapping state. is there.
