Description

本発明は、線材の表面に形成された被覆層を剥離する剥離装置に関する。   The present invention relates to a peeling apparatus for peeling a coating layer formed on the surface of a wire.

上記のような剥離装置の従来技術として、例えば特開2011−182597号公報(特許文献1)に記載された技術がある。なお、この背景技術の欄の説明では、〔〕内に特許文献1における部材名や符号を引用して説明する。特許文献1には、線材〔皮膜線1〕の被覆層を剥離する切削部材として、第一切削部材〔縦剥離カッタ10〕と第二切削部材〔横剥離カッタ60〕とを備える構成が記載されている。特許文献1の図3に示されているように、これらの第一切削部材と第二切削部材とは、線材の互いに異なる側面部の被覆層を剥離するように構成されている。また、第一切削部材により被覆層を剥離した後に、第二切削部材により被覆層を剥離する構成となっている。   As a conventional technique of the peeling apparatus as described above, for example, there is a technique described in Japanese Patent Application Laid-Open No. 2011-182597 (Patent Document 1). In the description of the background art section, the member names and symbols in Patent Document 1 are quoted in []. Patent Document 1 describes a configuration including a first cutting member [vertical peeling cutter 10] and a second cutting member [lateral peeling cutter 60] as a cutting member for peeling the coating layer of the wire [coated wire 1]. ing. As shown in FIG. 3 of Patent Document 1, the first cutting member and the second cutting member are configured to peel coating layers on different side portions of the wire. Moreover, after the coating layer is peeled off by the first cutting member, the coating layer is peeled off by the second cutting member.

ところで、第二切削部材は、第一切削部材により被覆層の剥離が行われた線材に対して被覆層の剥離を行うため、当該線材の外周面には、第一切削部材による切削厚さに相当する段差部が形成されている。そのため、第二切削部材による被覆層の剥離時に線材の被支持面が平坦でなく、線材を適切に支持することが難しい場合があると考えられる。しかしながら、特許文献1には、第二切削部材による被覆層の剥離に関する具体的構成が記載されておらず、上記の点について特段の認識がなされていなかった。被覆層の剥離装置を開示する別の文献である特開2002−209319号公報(特許文献2)についても同様である。   By the way, since the 2nd cutting member peels a coating layer with respect to the wire in which peeling of the coating layer was performed by the 1st cutting member, the cutting thickness by the 1st cutting member is formed in the outer peripheral surface of the said wire. A corresponding step portion is formed. Therefore, it is considered that the supported surface of the wire is not flat when the coating layer is peeled off by the second cutting member, and it may be difficult to support the wire appropriately. However, Patent Document 1 does not describe a specific configuration related to peeling of the coating layer by the second cutting member, and no particular recognition has been made regarding the above points. The same applies to Japanese Patent Application Laid-Open No. 2002-209319 (Patent Document 2), which is another document disclosing a coating layer peeling apparatus.

特開2011−182597号公報(段落0030、図3等)JP 2011-182597 A (paragraph 0030, FIG. 3, etc.) 特開2002−209319号公報JP 2002-209319 A

そこで、線材を異なる2つの方向から切削して被覆層を剥離する場合において、線材を適切に支持することが可能な剥離装置の実現が望まれる。   Therefore, in the case where the coating material is peeled by cutting the wire from two different directions, it is desired to realize a peeling device that can appropriately support the wire.

本発明に係る、線材の表面に形成された被覆層を剥離する剥離装置の特徴構成は、一対の刃部を有し、前記一対の刃部の間に形成される切削隙間の幅が、前記線材の延在方向に直交する方向である線材幅方向における、前記被覆層の剥離前の前記線材の幅以下に設定されている切削部材と、前記線材の剥離対象領域が前記切削隙間に収まるまで前記切削部材を切削方向に向けて移動させる切削動作と、前記切削部材を前記切削方向とは反対方向である戻り方向に向けて移動させる戻し動作と、を行なう切削駆動機構と、前記剥離対象領域に対して前記切削方向側から当接する切削方向側当接部を有し、前記剥離対象領域の前記切削方向側への移動を規制する線材移動規制機構と、を備え、前記切削部材として、前記延在方向を基準軸とする周方向の互いに異なる位置に配置された第一切削部材と第二切削部材とを備え、前記切削方向側当接部として、前記第一切削部材に対応する第一切削方向側当接部と前記第二切削部材に対応する第二切削方向側当接部とを備え、前記切削駆動機構は、前記第一切削部材を往復動作させた後に前記第二切削部材を往復動作させるとともに、前記切削駆動機構による前記第一切削部材及び前記第二切削部材のそれぞれの往復動作の軌跡が、前記線材の前記剥離対象領域において交差するように構成され、前記第二切削方向側当接部は、前記延在方向に隣接する隣接部に対して前記戻り方向側に突出するように形成された第二切削方向側当接面を有し、前記第二切削部材の前記切削動作の際に、前記第二切削方向側当接面が前記剥離対象領域に当接する点にある。   The characteristic configuration of the peeling apparatus according to the present invention for peeling the coating layer formed on the surface of the wire has a pair of blade parts, and the width of the cutting gap formed between the pair of blade parts is In the wire width direction, which is a direction orthogonal to the extending direction of the wire, until the cutting member set to be equal to or smaller than the width of the wire before peeling of the coating layer, and the separation target area of the wire fit in the cutting gap A cutting drive mechanism for performing a cutting operation for moving the cutting member in a cutting direction and a returning operation for moving the cutting member in a return direction opposite to the cutting direction; and the separation target region A cutting direction side abutting portion that abuts from the cutting direction side, and a wire rod movement regulating mechanism that regulates movement of the separation target region to the cutting direction side, and as the cutting member, Circumference with reference to the extending direction A first cutting member and a second cutting member disposed at different positions in the direction, and the first cutting direction side contact portion corresponding to the first cutting member and the first cutting direction side contact portion as the cutting direction side contact portion. A second cutting direction side contact portion corresponding to two cutting members, and the cutting drive mechanism reciprocates the second cutting member after reciprocating the first cutting member, and the cutting drive mechanism The trajectories of the reciprocating motions of the first cutting member and the second cutting member are intersected in the separation target region of the wire, and the second cutting direction side contact portion extends the extension A second cutting direction side contact surface formed so as to protrude toward the return direction side with respect to an adjacent portion adjacent to the direction, and the second cutting member performs the second cutting in the cutting operation of the second cutting member The direction-side contact surface contacts the separation target area There is a point.

上記の特徴構成によれば、第二切削部材の切削動作の際に線材の剥離対象領域に当接する第二切削方向側当接面が備えられるため、線材の切削方向側への移動を、刃部が接触する剥離対象領域に直接当接して規制することができる。よって、第二切削部材に切削動作を行わせる際における線材の変形量、特に、剥離対象領域の周辺部分の変形量を抑制することができる。
更に、上記の特徴構成によれば、切削駆動機構による第一切削部材及び第二切削部材のそれぞれの往復動作の軌跡が、線材の剥離対象領域において交差するように構成されるため、線材を延在方向に沿って移動させることなく、同一の剥離対象領域に対して、2つの切削部材により外周面の異なる位置の被覆層を剥離することができる。よって、当該2つの切削部材のそれぞれの往復動作が、線材の延在方向における異なる位置で実行される場合に比べ、剥離装置の当該延在方向における小型化を図ることができる。
According to said characteristic structure, since the 2nd cutting direction side contact surface contact | abutted to the peeling object area | region of a wire is provided in the case of the cutting operation of a 2nd cutting member, the movement to the cutting direction side of a wire is carried out, It is possible to regulate by directly abutting on the peeling target area where the part contacts. Therefore, the deformation amount of the wire when the second cutting member performs the cutting operation, particularly, the deformation amount of the peripheral portion of the separation target region can be suppressed.
Furthermore, according to the above-described characteristic configuration, the reciprocal trajectories of the first cutting member and the second cutting member by the cutting drive mechanism are configured to intersect in the separation target region of the wire, so that the wire is extended. Without moving along the existing direction, the coating layers at different positions on the outer peripheral surface can be peeled off by the two cutting members with respect to the same peeling target region. Therefore, compared with the case where each reciprocating operation of the two cutting members is performed at different positions in the extending direction of the wire, it is possible to reduce the size of the peeling device in the extending direction.

ここで、前記第二切削方向側当接面は、前記延在方向の長さが前記剥離対象領域の当該延在方向の長さ以下に設定されているとともに、前記延在方向に隣接する隣接部に対する前記戻り方向側への突出量が、前記第一切削部材による切削厚さ以上に設定されている構成とすると好適である。   Here, the second cutting direction-side contact surface is set so that the length in the extending direction is set to be equal to or less than the length in the extending direction of the separation target region, and is adjacent to the extending direction. It is preferable that the amount of protrusion toward the return direction with respect to the part is set to be equal to or greater than the cutting thickness of the first cutting member.

この構成によれば、第二切削部材の切削動作の際に、第二切削方向側当接面を剥離対象領域に対して良好に接触させることが容易となる。よって、第二切削部材に切削動作を行わせる際における線材の変形量、特に、剥離対象領域の周辺部分の変形量を効果的に抑制することができる。   According to this configuration, it is easy to satisfactorily contact the second cutting direction side contact surface with the separation target region during the cutting operation of the second cutting member. Therefore, the deformation amount of the wire when the second cutting member performs the cutting operation, in particular, the deformation amount of the peripheral portion of the separation target region can be effectively suppressed.

また、前記線材移動規制機構は、前記剥離対象領域に対して前記戻り方向側から当接する戻り方向側当接部を備え、前記剥離対象領域の前記戻り方向側への移動を規制するように構成され、前記戻り方向側当接部として、前記第一切削部材に対応する第一戻り方向側当接部と前記第二切削部材に対応する第二戻り方向側当接部とを備え、前記第二戻り方向側当接部は、前記延在方向に隣接する隣接部に対して前記切削方向側に突出するように形成された第二戻り方向側当接面を有し、前記第二切削部材の前記戻し動作の際に、前記第二戻り方向側当接面が前記剥離対象領域に当接する構成とすると好適である。   Further, the wire movement restriction mechanism includes a return direction side contact portion that contacts the separation target region from the return direction side, and is configured to restrict movement of the separation target region to the return direction side. The return direction side contact part includes a first return direction side contact part corresponding to the first cutting member and a second return direction side contact part corresponding to the second cutting member, The second return direction side contact portion has a second return direction side contact surface formed so as to protrude toward the cutting direction side with respect to an adjacent portion adjacent to the extending direction, and the second cutting member In the return operation, it is preferable that the second return direction contact surface is in contact with the separation target region.

この構成によれば、第二切削部材の戻し動作の際に線材の剥離対象領域に当接する第二戻り方向側当接面が備えられるため、線材の戻り方向側への移動を、刃部が接触する剥離対象領域に直接当接して規制することができる。よって、第二切削部材に戻し動作を行わせる際における線材の変形量、特に、剥離対象領域の周辺部分の変形量を抑制することができる。   According to this configuration, since the second return direction side contact surface that comes into contact with the separation target region of the wire is provided during the return operation of the second cutting member, the blade portion moves the wire in the return direction. It is possible to regulate by directly abutting against the peeling target area that comes into contact. Therefore, the deformation amount of the wire when the second cutting member performs the returning operation, particularly, the deformation amount of the peripheral portion of the separation target region can be suppressed.

上記のように前記第二戻り方向側当接部が前記第二戻り方向側当接面を有する構成において、前記第二戻り方向側当接面は、前記延在方向の長さが前記剥離対象領域の当該延在方向の長さ以下に設定されているとともに、前記延在方向に隣接する隣接部に対する前記切削方向側への突出量が、前記第一切削部材による切削厚さ以上に設定されている構成とすると好適である。   As described above, in the configuration in which the second return direction side contact portion has the second return direction side contact surface, the length of the second return direction side contact surface in the extending direction is the separation target. The length of the region is set to be equal to or less than the length in the extending direction, and the amount of protrusion of the adjacent portion adjacent to the extending direction toward the cutting direction is set to be equal to or greater than the cutting thickness of the first cutting member. It is preferable to adopt the configuration.

この構成によれば、第二切削部材の戻し動作の際に、第二戻り方向側当接面を剥離対象領域に対して良好に接触させることが容易となる。よって、第二切削部材に戻し動作を行わせる際における線材の変形量、特に、剥離対象領域の周辺部分の変形量を効果的に抑制することができる。   According to this configuration, it is easy to satisfactorily bring the second return direction side contact surface into contact with the separation target region during the returning operation of the second cutting member. Therefore, it is possible to effectively suppress the deformation amount of the wire rod when the second cutting member performs the returning operation, particularly the deformation amount of the peripheral portion of the separation target region.

上記の各構成の剥離装置において、前記第一切削方向側当接部及び前記第二切削方向側当接部の少なくとも一方は、前記剥離対象領域との当接面を有するとともに前記延在方向に延びる第一部分と、前記第一部分より前記切削方向側に位置する第二部分と、を備え、前記第一部分は、前記線材幅方向の幅が前記切削隙間より小さく設定されており、前記第二部分は、前記線材幅方向における前記線材の中央部に対して少なくとも一方側に、前記切削方向に向かうに従って前記線材の中央部側とは反対側に向かう傾斜面を有し、前記傾斜面は、前記第一部分の前記線材幅方向の側面に接続されている構成とすると好適である。   In the peeling device having each configuration described above, at least one of the first cutting direction side contact portion and the second cutting direction side contact portion has a contact surface with the separation target region and extends in the extending direction. A first portion that extends, and a second portion that is positioned closer to the cutting direction than the first portion, wherein the first portion has a width in the wire width direction set smaller than the cutting gap, and the second portion Is at least one side with respect to the central portion of the wire in the wire width direction, and has an inclined surface that goes to the opposite side to the central portion side of the wire as it goes to the cutting direction. It is preferable that the first portion is connected to the side surface in the wire width direction.

この構成によれば、第一切削部材及び第二切削部材の少なくとも一方について、被覆層を削り取る際に生じる削りくず(切りくず)を、傾斜面を利用して排出することができる。よって、削りくずが溜まることによって生じる問題、例えばメンテナンス頻度の増大や剥離性能の低下を回避することが容易となる。   According to this structure, about at least one of the first cutting member and the second cutting member, the shavings (chips) generated when the coating layer is scraped off can be discharged using the inclined surface. Therefore, it becomes easy to avoid problems caused by accumulation of shavings, such as an increase in maintenance frequency and a decrease in peeling performance.

flowchart which shows the procedure of the peeling method of the coating layer which concerns on embodiment of this invention.

本発明の実施形態について、図面を参照して説明する。本実施形態に係る剥離装置1は、図1及び図10等に示すように、延在方向Lに直交する断面形状が長方形状の線材2(平角線材)に対して、当該線材2の表面に形成された被覆層3の剥離を行う装置である。本明細書では、線材2における延在方向Lに沿った領域であって、被覆層3の剥離対象となる領域を「剥離対象領域2a」とする。被覆層3は、樹脂やセラミックス等の電気的絶縁材料により形成され、図10に示すように、銅やアルミニウム等の導電性材料により形成された導体部分4の外周全域(当該導体部分4の延在方向Lに直交する断面の外周全域)に形成されている。このような線材2は、例えば、電動機や発電機等の回転電機用のコイルに用いられる。なお、本実施形態では、図10に示すように、被覆層3の剥離前の線材2の延在方向Lに直交する断面形状と、上記導体部分4の延在方向Lに直交する断面形状との双方が、長方形状とされている。   Embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 10 and the like, the peeling device 1 according to the present embodiment has a cross-sectional shape orthogonal to the extending direction L on the surface of the wire 2 with respect to the wire 2 having a rectangular shape (flat wire). This is an apparatus for peeling the formed coating layer 3. In the present specification, a region along the extending direction L of the wire 2 that is a separation target of the coating layer 3 is referred to as a “peeling target region 2a”. The covering layer 3 is formed of an electrically insulating material such as resin or ceramics, and as shown in FIG. 10, the entire outer periphery of the conductor portion 4 formed of a conductive material such as copper or aluminum (the extension of the conductor portion 4). It is formed in the entire outer periphery of the cross section orthogonal to the existing direction L. Such a wire 2 is used for a coil for rotating electrical machines such as an electric motor and a generator. In the present embodiment, as shown in FIG. 10, a cross-sectional shape orthogonal to the extending direction L of the wire 2 before peeling of the coating layer 3 and a cross-sectional shape orthogonal to the extending direction L of the conductor portion 4 Both of them are rectangular.

以下の説明では、特に区別して明記している場合を除き、「周方向」及び「径方向」は、線材2の延在方向Lを基準軸とする方向である。すなわち、剥離装置1の各部についての各方向は、図1に示すように剥離装置1に配置された(セットされた)状態での線材2の延在方向Lを基準軸として定義している。また、以下の説明における各部材についての方向や位置等に関する用語は、製造上許容され得る誤差による差異を有する状態を含む概念として用いている。   In the following description, unless otherwise specified, “circumferential direction” and “radial direction” are directions with the extending direction L of the wire 2 as the reference axis. That is, each direction about each part of the peeling apparatus 1 defines the extending direction L of the wire 2 in a state where it is arranged (set) in the peeling apparatus 1 as shown in FIG. Moreover, the term regarding the direction, position, etc. about each member in the following description is used as a concept including the state which has the difference by the error which can be accept | permitted on manufacture.

剥離装置1は、図1及び図2に示すように、切削駆動機構10aと線材移動規制機構10bとを備えている。なお、図2は、図1と同じ状態においての剥離装置1の部分断面図を示している。詳細は後述するが、本実施形態では、切削駆動機構10aと線材移動規制機構10bとは、共通の部品を用いて一体的に形成されている。剥離装置1は、これらの切削駆動機構10a及び線材移動規制機構10bを作動させて、線材2の表面に形成された被覆層3を剥離する。
1. Overall Configuration of Peeling Device As shown in FIGS. 1 and 2, the peeling device 1 includes a cutting drive mechanism 10a and a wire movement restriction mechanism 10b. 2 shows a partial cross-sectional view of the peeling apparatus 1 in the same state as FIG.

And a straight line passing through the central portion in the radial direction. In order to surely peel the covering layer 3 on the side surface of the separation target region 2a, as shown in FIGS. 11 and 17, in this embodiment, the cutting direction side position is the cutting direction X1 of the separation target region 2a. The end on the X2 side is set on the cutting direction X1 and X2 side with respect to the position where it fits in the cutting gaps 32 and 42. In the present embodiment, the cutting direction side position is set radially inside from the return direction side position, so the cutting direction side position is the wire side position, and the return direction side position is the non-wire side position. is there.

(Inside), it is configured to reciprocate. That is, the trajectories of the reciprocating motions of the first cutting member 30 and the second cutting member 40 are configured to intersect the central portion in the radial direction at the same extending direction L position. Therefore, the reciprocating motion of the first cutting member 30 and the reciprocating motion trajectory of the second cutting member 40 are obtained by reciprocating each of the first cutting member 30 and the second cutting member 40 while the wire 2 is fixed. Can be crossed in the same separation target region 2a.

According to the shape of the wire 2, the first cutting member 30 and the second cutting member 40 are arranged at positions different from each other by 90 degrees in the circumferential direction as shown in FIG. The trajectories of the reciprocating motions of the cutting member 30 and the second cutting member 40 are configured to be orthogonal in the separation target region 2a. Thereby, the coating layer 3 formed in the side part of the both sides of the 1st wire width direction W1 is made to reciprocate each of the 1st cutting member 30 and the 2nd cutting member 40, and the 1st cutting member 30 and the 2nd It peels at one of the cutting members 40 (the first cutting member 30 in this example) (see FIGS. 10 and 11), and is formed on the side portions on both sides of the second wire width direction W2 orthogonal to the first wire width direction W1.

よって、第一被案内部材15aが案内される第一カム溝91における部位が第一大径部91a、第一小径部91b、及び第一大径部91aの順に変化するように、第一回転体11を回転させることで、第一切削部材30を往復動作させることができる。具体的には、第一切削部材30が戻り方向側位置から切削方向側位置を経て戻り方向側位置に戻るように、往復動作を一度行わせることができる。この際、第一被案内部材15aが案内される第一カム溝91における部位が、第一大径部91aから第一接続部91cを経て第一小径部91bへと変化する際に、第一切削部材30の切削動作が行われ、第一被案内部材15aが案内される第一カム溝91における部位が、第一小径部91bから第一接続部91cを経て第一大径部91aへと変化する際に、第一切削部材30の戻し動作が行われる。すなわち、切削動作及び戻し動作が記載の順に実行される。   Therefore, the first rotation is performed so that the portion of the first cam groove 91 in which the first guided member 15a is guided changes in the order of the first large diameter portion 91a, the first small diameter portion 91b, and the first large diameter portion 91a. The first cutting member 30 can be reciprocated by rotating the body 11. Specifically, the reciprocating operation can be performed once so that the first cutting member 30 returns from the return direction side position to the return direction side position through the cutting direction side position. At this time, when the portion of the first cam groove 91 in which the first guided member 15a is guided changes from the first large-diameter portion 91a to the first small-diameter portion 91b via the first connecting portion 91c. A portion of the first cam groove 91 where the cutting operation of the cutting member 30 is performed and the first guided member 15a is guided passes from the first small diameter portion 91b to the first large diameter portion 91a via the first connection portion 91c. When changing, the return operation of the first cutting member 30 is performed. That is, the cutting operation and the returning operation are executed in the order described.

図10は、第一切削部材30の切削動作の途中段階(後述する第一保持工程P11の終了時、図19参照)での第一切削部材30と剥離対象領域2aとの位置関係を示し、図11は、第一切削部材30の切削動作の終了段階(後述する第一切削工程P12の終了時、図19参照)での第一切削部材30と剥離対象領域2aとの位置関係を示している。図10に示すように、第一切削部材30の切削隙間32の幅(第一線材幅方向W1の幅)である第一隙間幅ΔS1は、被覆層3の剥離前の線材2の第一線材幅方向W1における幅である第一線材幅ΔR1以下に設定されている。また、第一線材幅方向W1の位置関係において、切削隙間32の中央部と線材2の中央部との位置が合うように、第一切削部材30が線材2に対して配置される。よって、図11に示すように、一度の切削動作により、剥離対象領域2aにおける第一線材幅方向W1の両側の側面部の被覆層3が削り取られる。   FIG. 10 shows the positional relationship between the first cutting member 30 and the separation target region 2a in the middle stage of the cutting operation of the first cutting member 30 (at the end of the first holding step P11 described later, see FIG. 19). FIG. 11 shows the positional relationship between the first cutting member 30 and the separation target region 2a at the end stage of the cutting operation of the first cutting member 30 (at the end of the first cutting step P12 described later, see FIG. 19). Yes. As shown in FIG. 10, the first gap width ΔS <b> 1, which is the width of the cutting gap 32 of the first cutting member 30 (the width in the first wire width direction W <b> 1), is the first wire rod of the wire 2 before the coating layer 3 is peeled off. It is set to be equal to or less than the first wire width ΔR1 which is the width in the width direction W1. Further, the first cutting member 30 is arranged with respect to the wire 2 so that the center of the cutting gap 32 and the center of the wire 2 are aligned in the positional relationship in the first wire width direction W1. Therefore, as shown in FIG. 11, the coating layer 3 on the side surfaces on both sides in the first wire width direction W1 in the separation target region 2a is scraped off by a single cutting operation.

なお、本実施形態では、第一隙間幅ΔS1は、第一線材幅ΔR1以下であるという制約の下で、第一線材幅方向W1における導体部分4の幅に基づき設定されている。例えば、第一隙間幅ΔS1を、第一線材幅方向W1における導体部分4の幅と同じ値に設定し、或いは、第一線材幅方向W1における導体部分4の幅より誤差分だけ小さく設定することができる。なお、誤差分は、例えば、各部材の寸法や配置位置の第一線材幅方向W1における公差に基づく量とすることができる。このような誤差分を考慮することで、剥離対象領域2aにおける第一線材幅方向W1の両側の側面部の被覆層3の全てを、第一切削部材30により確実に削り取ることが容易となる。なお、第一切削部材30の少なくとも第一刃部31は、導体部分4より硬度の高い材料で形成されており、本実施形態では、第一隙間幅ΔS1は第一線材幅方向W1における導体部分4の幅より誤差分だけ狭く設定されている。よって、第一線材幅方向W1における少なくとも一方側の側面部(実際上、両側の側面部)において、被覆層3とともに導体部分4の一部(実用上問題のない程度の割合)も削り取られる。すなわち、本実施形態では、第一切削部材30による線材の切削厚さ(後述する)は、設計上、被覆層3の厚さより大きくなっている。   In the present embodiment, the first gap width ΔS1 is set based on the width of the conductor portion 4 in the first wire width direction W1 under the constraint that it is equal to or less than the first wire width ΔR1. For example, the first gap width ΔS1 is set to the same value as the width of the conductor portion 4 in the first wire width direction W1, or is set smaller than the width of the conductor portion 4 in the first wire width direction W1 by an error. Can do. Note that the error can be, for example, an amount based on tolerances in the first wire width direction W1 of the dimensions and arrangement positions of the members. By taking such an error into account, it becomes easy to surely scrape off all of the coating layer 3 on the side surfaces on both sides in the first wire width direction W1 in the separation target region 2a with the first cutting member 30. Note that at least the first blade portion 31 of the first cutting member 30 is formed of a material having a hardness higher than that of the conductor portion 4, and in the present embodiment, the first gap width ΔS1 is a conductor portion in the first wire width direction W1. It is set narrower by an error than the width of 4. Therefore, at least one side surface portion (actually, the side surface portions on both sides) in the first wire width direction W <b> 1, a portion of the conductor portion 4 is also scraped off together with the covering layer 3. That is, in this embodiment, the cutting thickness (described later) of the wire rod by the first cutting member 30 is larger than the thickness of the coating layer 3 by design.

第二可動部材14bは、図1及び図2に示すように、周方向の配設位置が異なる点を除いて第一可動部材14aと同様に構成されており、第一被案内部材15aに対応する第二被案内部材15bを備えている。第二可動部材14bの径方向内側の端部には、第二切削部材40が固定されている。そして、第二被案内部材15bが案内される第一カム溝91における部位が、第一大径部91a、第一小径部91b、及び第一大径部91aの順に変化するように第一回転体11を回転させることで、第二切削部材40についての切削動作及び戻し動作を順に実行することができる。また、第二切削部材40の第二切削隙間42の幅(第二線材幅方向W2の幅)である第二隙間幅ΔS2(図16参照)は、被覆層3の剥離前の線材2の第二線材幅方向W2における幅である第二線材幅ΔR2に第一線材幅ΔR1が置き換わる点を除いて、第一隙間幅ΔS1と同様に設定されている。すなわち、第二隙間幅ΔS2は、第二線材幅ΔR2以下に設定され、本実施形態では、第二隙間幅ΔS2は、第二線材幅ΔR2以下であるという制約の下で、第二線材幅方向W2における導体部分4の幅に基づき設定されている。   As shown in FIGS. 1 and 2, the second movable member 14b is configured in the same manner as the first movable member 14a except that the arrangement position in the circumferential direction is different, and corresponds to the first guided member 15a. The second guided member 15b is provided. A second cutting member 40 is fixed to the radially inner end of the second movable member 14b. Then, the first rotation is performed so that the portion of the first cam groove 91 in which the second guided member 15b is guided changes in the order of the first large diameter portion 91a, the first small diameter portion 91b, and the first large diameter portion 91a. By rotating the body 11, the cutting operation and the returning operation for the second cutting member 40 can be executed in order. Further, the second gap width ΔS2 (see FIG. 16), which is the width of the second cutting gap 42 of the second cutting member 40 (width in the second wire width direction W2), is the first width of the wire 2 before peeling of the coating layer 3. It is set in the same manner as the first gap width ΔS1 except that the first wire width ΔR1 is replaced with the second wire width ΔR2, which is the width in the two-wire width direction W2. That is, the second gap width ΔS2 is set to be equal to or smaller than the second wire width ΔR2, and in the present embodiment, the second gap width ΔS2 is limited to the second wire width ΔR2 or less in the second wire width direction. It is set based on the width of the conductor portion 4 at W2.

本実施形態では、以下のような構成を備えることで、第一回転体11を周方向における一方側に向けて180度(すなわち半周)回転させる間に、第一切削部材30の往復動作と第二切削部材40の往復動作とが互いに異なるタイミングで実行されるように構成されている。すなわち、図2に示すように、第一カム溝91は、延在方向Lを対称軸とする180度の回転対称性を有する形状に形成されており、第一小径部91bは、互いに180度異なる周方向の位置のそれぞれに設けられている。また、第一小径部91b及び当該第一小径部91bの周方向の両側の2つの第一接続部91cが占める周方向の範囲は、90度未満の周方向範囲とされている。そして、本実施形態では、同一の剥離対象領域2aに対して、第一切削部材30が往復動作した後に第二切削部材40が往復動作するように、すなわち、複数の切削部材30,40が順に往復動作するように、第一回転体11の回転方向や初期位置が設定されている。   In the present embodiment, by providing the following configuration, the first cutting member 30 is reciprocated and rotated while the first rotating body 11 is rotated 180 degrees (that is, a half circumference) toward one side in the circumferential direction. The reciprocating operation of the two cutting members 40 is performed at different timings. That is, as shown in FIG. 2, the first cam grooves 91 are formed in a shape having a rotational symmetry of 180 degrees with the extending direction L as the symmetry axis, and the first small diameter portions 91 b are 180 degrees relative to each other. It is provided at each of different circumferential positions. Further, the circumferential range occupied by the first small diameter portion 91b and the two first connection portions 91c on both sides in the circumferential direction of the first small diameter portion 91b is a circumferential range of less than 90 degrees. And in this embodiment, after the 1st cutting member 30 reciprocates with respect to the same peeling object area | region 2a, the 2nd cutting member 40 reciprocates, ie, the some cutting members 30 and 40 are in order. The rotational direction and initial position of the first rotating body 11 are set so as to reciprocate.

例えば、図1に示すように第一回転体11の回転方向(白抜き矢印の指す向き、すなわち、図2における反時計回り方向側)及び初期位置を設定することができる。この場合、第一切削部材30及び第二切削部材40の双方が戻り方向側位置に位置する図1に示す状態から、第一回転体11を回転方向側に45度回転させることで、第二切削部材40の位置は戻り方向側位置から変化せずに第一切削部材30が切削方向側位置に位置する図7に示す状態となる。図7に示す状態から更に第一回転体11を回転方向側に90度(すなわち、初期位置から135度)回転させることで、第一切削部材30が戻り方向側位置に戻るとともに第二切削部材40が切削方向側位置に位置する図13に示す状態となる。   For example, as shown in FIG. 1, the rotation direction (the direction indicated by the white arrow, that is, the counterclockwise direction in FIG. 2) and the initial position of the first rotating body 11 can be set. In this case, the first rotary member 11 is rotated 45 degrees in the rotation direction side from the state shown in FIG. 1 in which both the first cutting member 30 and the second cutting member 40 are located at the return direction side position, thereby the second The position of the cutting member 40 does not change from the return direction side position, and the first cutting member 30 is in the state shown in FIG. When the first rotating body 11 is further rotated 90 degrees in the rotation direction side (that is, 135 degrees from the initial position) from the state shown in FIG. 7, the first cutting member 30 returns to the return direction side position and the second cutting member. 40 is in the state shown in FIG.

そして、図13に示す状態から更に第一回転体11を回転方向側に45度(すなわち、初期位置から180度)回転させることで、第一切削部材30及び第二切削部材40の双方が戻り方向側位置に位置する図1に示す状態(但し、第一回転体11の回転位置は初期位置とは180度異なる)に戻る。よって、次の剥離対象領域2aに対する第一切削部材30及び第二切削部材40のそれぞれの往復動作は、第一回転体11を初期位置に戻すことなく、第一回転体11の回転位置が初期位置とは180度ずれた状態から第一回転体11を回転方向側に180度回転させることで実現される。すなわち、本実施形態では、第一回転体11の回転方向を一方向にすることができ、第一回転体11を回転駆動する駆動機構(図示せず)の簡素化を図ることが可能となっている。   Then, both the first cutting member 30 and the second cutting member 40 are returned by further rotating the first rotating body 11 45 degrees in the rotation direction side (ie, 180 degrees from the initial position) from the state shown in FIG. Returning to the state shown in FIG. 1 located at the direction side position (however, the rotational position of the first rotating body 11 is 180 degrees different from the initial position). Therefore, the reciprocating operation of the first cutting member 30 and the second cutting member 40 with respect to the next separation target region 2a does not return the first rotating body 11 to the initial position, and the rotational position of the first rotating body 11 is the initial. The position is realized by rotating the first rotating body 11 180 degrees in the rotation direction side from a state shifted by 180 degrees. That is, in the present embodiment, the rotation direction of the first rotating body 11 can be set to one direction, and it is possible to simplify the driving mechanism (not shown) that rotationally drives the first rotating body 11. ing.

3-1. Configuration of Cutting Direction Side Contact Member The first cutting direction side contact member 50 includes a first main body portion 51 and a first attachment portion 54 as shown in FIGS. 3 and 4. 3 and 4 and FIGS. 5 and 6 to be referred to later, the members are shown separated from each other along the reciprocal movement directions A1 and A2 in order to facilitate understanding of the configuration of each member. . As shown in FIG. 2, the first cutting direction side contact member 50 is disposed at a position 180 degrees different from the first cutting member 30 in the circumferential direction. And the 1st attaching part 54 is a part for attaching the 1st cutting direction side contact member 50 to the member which supports the said member, and in this embodiment, as shown in FIG. The first cutting direction side contact member 50 is fixed to the third movable member 14 c via 54.

第一本体部51は、図3及び図4に示すように、第一戻り方向Y1側に突出した状態で延在方向Lに沿って線状に延びる第一突出部52と、第一突出部52より第一切削方向X1側に位置して当該第一突出部52を支持する第一支持部53とを備えている。そして、第一突出部52の第一戻り方向Y1側の面が、剥離対象領域2aとの当接面である第一切削方向側当接面52aとされる。第一突出部52の延在方向Lの長さは、図8に示すように第一刃幅ΔT1より大きく設定される。すなわち、第一突出部52は、延在方向Lの長さが剥離対象領域2aより大きく設定され、本実施形態では、第一突出部52の延在方向Lの長さは、後述する第一貫通幅ΔU1と等しくなっている。本実施形態では、第一突出部52が、本発明における第一切削方向側当接部についての「第一部分」に相当し、第一支持部53が、本発明における第一切削方向側当接部についての「第二部分」に相当する。   As shown in FIGS. 3 and 4, the first main body 51 includes a first protrusion 52 extending linearly along the extending direction L in a state of protruding toward the first return direction Y <b> 1, and a first protrusion 52 and a first support portion 53 that is located on the first cutting direction X1 side and supports the first projecting portion 52. And the surface by the side of the 1st return direction Y1 of the 1st protrusion part 52 is made into the 1st cutting direction side contact surface 52a which is a contact surface with the peeling object area | region 2a. The length in the extending direction L of the first protrusion 52 is set to be larger than the first blade width ΔT1 as shown in FIG. That is, the length of the first protruding portion 52 in the extending direction L is set to be larger than that of the separation target region 2a. In the present embodiment, the length of the first protruding portion 52 in the extending direction L is the first described later. It is equal to the penetration width ΔU1. In this embodiment, the 1st protrusion part 52 is corresponded to the "1st part" about the 1st cutting direction side contact part in this invention, and the 1st support part 53 is the 1st cutting direction side contact in this invention. This corresponds to the “second part” of the part.

また、第一突出部52は、図10に示すように、第一線材幅方向W1の幅が第一切削隙間32より小さく設定される。本実施形態では、第一突出部52は、第一線材幅方向W1の幅が導体部分4よりも小さく設定されている。これにより、図9及び図11に示すように、第一突出部52が第一切削隙間32に収まるように第一切削部材30を第一切削方向側当接部材50に対して配置することが可能となっている。なお、本実施形態では、第一突出部52は、第一線材幅方向W1の幅が後述する第一戻り方向側当接部材70の第一当接部71と等しくなっている。   Further, as shown in FIG. 10, the first protrusion 52 is set to have a width in the first wire width direction W <b> 1 smaller than the first cutting gap 32. In the present embodiment, the first protrusion 52 is set to have a width in the first wire rod width direction W <b> 1 smaller than that of the conductor portion 4. Accordingly, as shown in FIGS. 9 and 11, the first cutting member 30 can be arranged with respect to the first cutting direction side contact member 50 so that the first projecting portion 52 is accommodated in the first cutting gap 32. It is possible. In the present embodiment, the first projecting portion 52 has the same width in the first wire width direction W1 as the first contact portion 71 of the first return direction side contact member 70 described later.

図3及び図4に示すように、第一突出部52の延在方向Lの両側には、第一移動規制溝56が形成されている。第一移動規制溝56は、第一線材幅方向W1の両側に第一往復動作方向A1に沿って延びる側壁部を有し、第一移動規制溝56の第一線材幅方向W1の幅は、第一線材幅ΔR1(図10参照)より僅かに大きく形成されている。すなわち、第一移動規制溝56は、第一線材幅方向W1の幅が第一突出部52よりも大きく形成されている。また、上記側壁部は、第一切削方向側当接面52aより第一戻り方向Y1側まで延びるように形成されている。これにより、図8及び図10に示すように、剥離対象領域2aが第一切削方向側当接面52aに当接した状態で、第一移動規制溝56により、線材2の第一線材幅方向W1における移動を剥離対象領域2aに対して延在方向Lの両側で規制することが可能となっている。なお、線材2の第一切削方向X1側の部分が第一移動規制溝56内に確実に挿入されるように、上記側壁部の第一戻り方向Y1側の端部には、図3及び図10に示すように、第一戻り方向Y1に向かうに従って第一線材幅方向W1における線材2の中央部(すなわち第一移動規制溝56の中央部)とは反対側に向かう第一面取り部56aが接続されている。   As shown in FIGS. 3 and 4, first movement restriction grooves 56 are formed on both sides in the extending direction L of the first protrusion 52. The first movement restriction groove 56 has side wall portions extending along the first reciprocating movement direction A1 on both sides of the first wire width direction W1, and the width of the first movement restriction groove 56 in the first wire width direction W1 is: It is formed slightly larger than the first wire rod width ΔR1 (see FIG. 10). That is, the first movement restriction groove 56 is formed so that the width in the first wire rod width direction W <b> 1 is larger than that of the first protrusion 52. Moreover, the said side wall part is formed so that it may extend to the 1st return direction Y1 side from the 1st cutting direction side contact surface 52a. Accordingly, as shown in FIGS. 8 and 10, the first movement restriction groove 56 allows the separation target region 2 a to be in contact with the first cutting direction side contact surface 52 a, so that the first wire rod width direction of the wire 2. The movement in W1 can be restricted on both sides in the extending direction L with respect to the separation target region 2a. 3 and FIG. 3 at the end of the side wall portion on the first return direction Y1 side so that the portion on the first cutting direction X1 side of the wire 2 is surely inserted into the first movement restricting groove 56. As shown in FIG. 10, the first chamfered portion 56 a heading toward the opposite side to the central portion of the wire 2 in the first wire width direction W1 (that is, the central portion of the first movement restriction groove 56) as it goes in the first return direction Y1. It is connected.

本実施形態では、図3に示すように、第一支持部53は、第一線材幅方向W1における線材2の中央部(すなわち、第一突出部52の中央部)に対して少なくとも一方側に、第一切削方向X1に向かうに従って線材2の中央部側とは反対側に向かう第一傾斜面53aを有している。本実施形態では、第一傾斜面53aは、第一線材幅方向W1における線材2の中央部に対して両側に形成されており、第一傾斜面53aのそれぞれは、第一突出部52の第一線材幅方向W1の側面であって、線材2の中央部に対して第一線材幅方向W1の同じ側に位置する側面に接続されている。これにより、図11に示すように第一切削部材30により被覆層3を削り取る際に生じる削りくず(切りくず)を、第一線材幅方向W1の両側において、第一切削方向X1側に適切に排出することが可能となっている。   In the present embodiment, as shown in FIG. 3, the first support portion 53 is at least on one side with respect to the central portion of the wire 2 (that is, the central portion of the first protruding portion 52) in the first wire width direction W <b> 1. The first inclined surface 53a is directed toward the opposite side of the central portion side of the wire 2 toward the first cutting direction X1. In the present embodiment, the first inclined surfaces 53 a are formed on both sides with respect to the central portion of the wire 2 in the first wire width direction W <b> 1, and each of the first inclined surfaces 53 a is the first protrusion 52. It is a side surface in one wire rod width direction W1 and is connected to a side surface located on the same side in the first wire rod width direction W1 with respect to the central portion of the wire rod 2. As a result, as shown in FIG. 11, the shavings (chips) generated when the coating layer 3 is scraped off by the first cutting member 30 are appropriately applied to the first cutting direction X1 side on both sides of the first wire width direction W1. It is possible to discharge.

更に、本実施形態では、第一移動規制溝56は、図3及び図8に示すように、底面(第一戻り方向Y1側を向く面)の第一往復動作方向A1における位置が第一切削方向側当接面52aと同じ位置となるように形成されている。よって、図8に示すように、剥離対象領域2aが第一切削方向側当接面52aに当接した状態で、第一移動規制溝56は、線材2における剥離対象領域2aに対して延在方向Lの両側に位置する部分に対して、第一切削方向X1側から当接する。すなわち、本実施形態では、線材2は、第一切削方向側当接部材50により、当該第一切削方向側当接部材50の延在方向Lの全域で第一切削方向X1側から支持される。   Furthermore, in the present embodiment, as shown in FIGS. 3 and 8, the first movement restricting groove 56 has a position in the first reciprocating motion direction A1 of the bottom surface (the surface facing the first return direction Y1). It forms so that it may become the same position as the direction side contact surface 52a. Therefore, as illustrated in FIG. 8, the first movement restriction groove 56 extends with respect to the separation target region 2 a in the wire 2 in a state where the separation target region 2 a is in contact with the first cutting direction side contact surface 52 a. The part located on both sides in the direction L is in contact with the first cutting direction X1. That is, in this embodiment, the wire 2 is supported by the first cutting direction side contact member 50 from the first cutting direction X1 side in the entire extending direction L of the first cutting direction side contact member 50. .

The configuration of the contact surface 62a is the same as that of the first cutting direction side contact member 50 except that the configuration of the contact surface 62a is different from that of the first cutting direction side contact surface 52a. That is, the second cutting direction side contact member 60 corresponds to the second main body portion 61 corresponding to the first main body portion 51, the second protrusion portion 62 corresponding to the first protrusion portion 52, and the first support portion 53 corresponding to the first support portion 53. Two support portions 63, a second inclined surface 63a corresponding to the first inclined surface 53a, a second attachment portion 64 corresponding to the first attachment portion 54, a second movement restriction groove 66 corresponding to the first movement restriction groove 56, a second A second chamfered portion 66a corresponding to the one chamfered portion 56a is provided. Each part of the second cutting direction side contact member 60 has a first reciprocating motion direction A1, a first cutting direction X1, a first return direction Y1, and a first wire width direction W1, respectively. Except for the point that it is replaced with A2, the second cutting direction X2, the second return direction Y2, and the second wire width direction W2, it is configured in the same manner as the corresponding part in the first cutting direction side contact member 50. And in this embodiment, as shown in FIG. 14, the 2nd cutting direction side contact member 60 is being fixed to the 4th movable member 14d via the 2nd attachment part 64. As shown in FIG. In this embodiment, the 2nd protrusion part 62 is corresponded to the "1st part" about the 2nd cutting direction side contact part in this invention, and the 2nd support part 63 is the 2nd cutting direction side contact in this invention. This corresponds to the “second part” of the part.

図14に示すように、第二突出部62の延在方向Lの長さは、第二刃幅ΔT2より大きく設定され、本実施形態では、後述する第二貫通幅ΔU2と等しくなっている。また、図16に示すように、第二突出部62は、第二線材幅方向W2の幅が第二切削隙間42より小さく設定され、本実施形態では、第二突出部62の第二線材幅方向W2の幅は、導体部分4よりも小さく設定されている。なお、本実施形態では、第二突出部62は、第二線材幅方向W2の幅が後述する第二戻り方向側当接部材80の第二当接部81と等しくなっている。   As shown in FIG. 14, the length of the second protrusion 62 in the extending direction L is set to be larger than the second blade width ΔT2, and in the present embodiment, is equal to a second penetration width ΔU2 described later. Moreover, as shown in FIG. 16, the 2nd protrusion part 62 sets the width | variety of the 2nd wire rod width direction W2 smaller than the 2nd cutting gap 42, and in this embodiment, the 2nd wire rod width | variety of the 2nd protrusion part 62 is shown. The width in the direction W <b> 2 is set smaller than the conductor portion 4. In the present embodiment, the second protrusion 62 has the same width in the second wire width direction W2 as the second contact portion 81 of the second return direction contact member 80 described later.

第二移動規制溝66は、図16に示すように、第二線材幅方向W2の幅が第二線材幅ΔR2より僅かに大きく形成されている。そして、第二移動規制溝66が有する、第二線材幅方向W2の両側において第二往復動作方向A2に沿って延びる側壁部は、第二突出部62の第二戻り方向Y2側の面である第二切削方向側当接面62aより第二戻り方向Y2側まで延びるように形成されている。本実施形態では、第二支持部63は、第二線材幅方向W2における線材2の中央部(すなわち、第二突出部62の中央部)に対して両側に、第二傾斜面63aを有している。すなわち、本実施形態では、第一切削方向側当接部材50及び第二切削方向側当接部材60の双方が、線材幅方向W1,W2における線材2の中央部に対して両側に、傾斜面53a,63aを備えている。   As shown in FIG. 16, the second movement restricting groove 66 is formed such that the width in the second wire width direction W2 is slightly larger than the second wire width ΔR2. And the side wall part which extends along the 2nd reciprocation direction A2 in the both sides of the 2nd wire rod width direction W2 which the 2nd movement control groove 66 has is a surface by the side of the 2nd return direction Y2 of the 2nd protrusion part 62. It is formed so as to extend from the second cutting direction side contact surface 62a to the second return direction Y2 side. In this embodiment, the 2nd support part 63 has the 2nd inclined surface 63a on both sides with respect to the center part (namely, center part of the 2nd protrusion part 62) of the wire 2 in the 2nd wire width direction W2. ing. That is, in this embodiment, both the first cutting direction side contact member 50 and the second cutting direction side contact member 60 are inclined surfaces on both sides with respect to the central portion of the wire 2 in the wire width direction W1, W2. 53a, 63a.

ところで、第二切削方向側当接部材60は、第一切削部材30及び第二切削部材40の内の往復動作の順が後である第二切削部材40に対応する切削方向側当接部材である。すなわち、図14及び図16に示すように、第二切削部材40の往復動作を行う際の剥離対象領域2aにおける第二切削方向側当接部材60側(第二切削方向X2側)の側面部は、第一切削部材30により被覆層3が削り取られた側面部である。このような剥離対象領域2aの側面部に対して第二切削方向側当接面62aを確実に当接させるべく、第二切削方向側当接面62aは、図5、図6、及び図14に示すように、延在方向Lに隣接する隣接部65に対して第二戻り方向Y2側に突出するように形成されている。   By the way, the second cutting direction side contact member 60 is a cutting direction side contact member corresponding to the second cutting member 40 in which the order of the reciprocating operation of the first cutting member 30 and the second cutting member 40 is later. is there. That is, as shown in FIGS. 14 and 16, the side surface portion on the second cutting direction side contact member 60 side (second cutting direction X2 side) in the separation target region 2 a when the second cutting member 40 performs the reciprocating operation. These are side portions from which the coating layer 3 has been scraped off by the first cutting member 30. In order to ensure that the second cutting direction side contact surface 62a comes into contact with the side surface portion of the separation target region 2a, the second cutting direction side contact surface 62a is formed as shown in FIGS. As shown in FIG. 6, the second protrusions are formed so as to protrude toward the second return direction Y2 with respect to the adjacent portion 65 adjacent in the extending direction L.

図14に示すように、第二切削方向側当接面62aは、延在方向Lの長さが剥離対象領域2aの延在方向Lの長さ以下に設定される。上述したように、本実施形態では、剥離対象領域2aの延在方向Lの長さは、刃幅ΔT1,ΔT2と同一の値とされる。本実施形態では、延在方向Lにおいて誤差が生じた場合にも第二切削方向側当接面62aを延在方向Lの全域で剥離対象領域2aに対して当接させることを可能とすべく、第二切削方向側当接面62aの延在方向Lの長さが、剥離対象領域2aの延在方向Lの長さより予め定められた量だけ短い値に設定されている。この予め定められた量は、例えば、各部材の寸法や配置位置の延在方向Lにおける公差に基づく量とすることができる。   As shown in FIG. 14, the length in the extending direction L of the second cutting direction side contact surface 62a is set to be equal to or less than the length in the extending direction L of the separation target region 2a. As described above, in the present embodiment, the length in the extending direction L of the separation target region 2a is the same value as the blade widths ΔT1 and ΔT2. In the present embodiment, even when an error occurs in the extending direction L, the second cutting direction side contact surface 62a can be brought into contact with the separation target region 2a in the entire extending direction L. The length in the extending direction L of the second cutting direction side contact surface 62a is set to a value shorter than the length in the extending direction L of the separation target region 2a by a predetermined amount. The predetermined amount can be, for example, an amount based on tolerances in the extending direction L of the dimensions and arrangement positions of the members.

また、第二切削方向側当接面62aは、延在方向Lに隣接する隣接部65に対する第二戻り方向Y2側への突出量ΔP(図16参照)が、第一切削部材30による線材2の切削厚さ以上に設定される。なお、ここでいう「切削厚さ」は、設計上の厚さであり、第一切削部材30による線材2の設計上の切削厚さは、図10から明らかなように、{(ΔR1−ΔS1)/2}により導出される。本実施形態では、第一切削部材30による線材2の実際の切削厚さが第一線材幅方向W1の両側で不均一になった場合にも、第二切削方向側当接面62aを剥離対象領域2aに対して当接させることを可能とすべく、突出量ΔPが、{(ΔR1−ΔS1)/2}に予め定められた量を加算した値に設定されている。この予め定められた量は、例えば、各部材の寸法や配置位置の第一線材幅方向W1における公差に基づく量とすることができる。このような構成を備えるため、本実施形態では、設計上、図14及び図16に示すように、第二切削方向側当接部材60における第二切削方向側当接面62aのみが、線材2(剥離対象領域2a)に対して第二切削方向X2側から当接する。すなわち、設計上、第二移動規制溝66の底面(第二戻り方向Y2側を向く面)は、線材2に当接しない構成となっている。   Further, the second cutting direction side contact surface 62a has a protrusion amount ΔP (see FIG. 16) in the second return direction Y2 side with respect to the adjacent portion 65 adjacent to the extending direction L, so that the wire 2 by the first cutting member 30 is used. It is set to more than the cutting thickness. The “cutting thickness” here is a designed thickness, and the designed cutting thickness of the wire 2 by the first cutting member 30 is {(ΔR1−ΔS1) as is apparent from FIG. ) / 2}. In the present embodiment, even when the actual cutting thickness of the wire 2 by the first cutting member 30 becomes uneven on both sides in the first wire width direction W1, the second cutting direction side contact surface 62a is peeled off. The protrusion amount ΔP is set to a value obtained by adding a predetermined amount to {(ΔR1−ΔS1) / 2} so that it can be brought into contact with the region 2a. The predetermined amount can be, for example, an amount based on tolerances in the first wire rod width direction W1 of the dimensions and arrangement positions of the members. In order to provide such a configuration, in the present embodiment, as shown in FIGS. 14 and 16, only the second cutting direction side contact surface 62 a in the second cutting direction side contact member 60 is designed to be the wire 2. It abuts on the (peeling target region 2a) from the second cutting direction X2 side. That is, by design, the bottom surface of the second movement restriction groove 66 (the surface facing the second return direction Y2 side) is configured not to contact the wire 2.

The first connecting member 16 a is connected to each of the portions 72. And in this embodiment, as shown in FIG. 8, the 1st return direction side contact member 70 is attached to the 1st movable member 14a via the 1st connection member 16a. That is, in the present embodiment, the first return direction side contact member 70 is attached to the first movable member 14 a in the same manner as the first cutting member 30. Although the details will be described later, unlike the first cutting member 30, the first return direction contact member 70 is configured to be movable in the radial direction with respect to the first movable member 14a.

なお、本実施形態では、図4に示すように、第一支持部72の第一切削方向X1側の面は、第一往復動作方向A1の位置が第一戻り方向側当接面71aと同じ位置に形成されている。そのため、図8に示すように、剥離対象領域2aが第一戻り方向側当接面71aに当接した状態で、第一支持部72の第一切削方向X1側の面が、線材2における剥離対象領域2aに対して延在方向Lの両側に位置する部分に対して、第一戻り方向Y1側から当接する。   In the present embodiment, as shown in FIG. 4, the surface on the first cutting direction X1 side of the first support portion 72 has the same position in the first reciprocating operation direction A1 as the first return direction side contact surface 71a.

As described above, in the present embodiment, the length in the extending direction L of the separation target region 2a is the same value as the blade widths ΔT1 and ΔT2. And the 1st return direction side contact member 70 is the both sides which pinched | interposed the center part (namely, center part of the 1st contact part 71) of the wire 2 in the 1st wire width direction W1, as shown in FIG. Each has a first through portion 73 penetrating in the reciprocating direction of the first cutting member 30 by the cutting drive mechanism 10a (that is, the first reciprocating direction A1). Specifically, the side surface of the first contact portion 71 in the first wire width direction W1 and the side surface of each of the pair of first support portions 72 facing the central portion side in the extending direction L (that is, the extending direction L).

In the present embodiment, as shown in FIGS. 3 and 4, the width in the extending direction L of the first through portion 73 is uniform along the first wire width direction W1. Further, the pair of first through portions 73 are formed to have the same width in the extending direction L, and in the present embodiment, the widths in the first wire width direction W1 are also formed to be equal to each other.

That is, if the width in the extending direction L of the first penetration portion 73 is the first penetration width ΔU1, as shown in FIG. 8, the first penetration width ΔU1 is set larger than the first blade width ΔT1. As shown in FIG. 10, the first contact portion 71 is set such that the width in the first wire width direction W1 is smaller than the first cutting gap 32 (first gap width ΔS1).

The portion in the two cutting directions X2 side) is formed such that the length in the extending direction L is equal to or less than the second blade width ΔT2 (see FIG. 14) (same as the second blade width ΔT2 in this example). Further, as shown in FIG. 17, the second cutting member 40 includes a gap in the second wire width direction W <b> 2 (hereinafter referred to as “second”) formed so as to be continuous from the second cutting gap 42 to the second return direction Y <b> 2 side. A continuous gap ”). The second continuous gap has an end portion on the second return direction Y2 side that is more than the second contact portion 81 in the state where the second cutting member 40 is disposed at the cutting direction side position (state in FIG. 17). It is formed so as to be positioned on the second return direction Y2 side, and is formed so that the width in the second wire width direction W2 is equal to or larger than the second gap width ΔS2 over the entire area in the second reciprocating operation direction A2.

図14及び図16に示すように、第二切削部材40の往復動作を行う際の剥離対象領域2aにおける第二戻り方向側当接部材80側(第二戻り方向Y2側)の側面部は、第一切削部材30により被覆層3が削り取られた側面部である。このような剥離対象領域2aの側面部に対して第二戻り方向側当接面81aを確実に当接させるべく、第二戻り方向側当接面81aは、図5、図6、及び図14に示すように、延在方向Lに隣接する隣接部85に対して第二切削方向X2側に突出するように形成されている。   As shown in FIGS. 14 and 16, the side portion on the second return direction side contact member 80 side (second return direction Y2 side) in the separation target region 2a when the reciprocating operation of the second cutting member 40 is performed, It is a side surface part in which the coating layer 3 is scraped off by the first cutting member 30. In order to ensure that the second return direction side contact surface 81a comes into contact with the side surface portion of the separation target region 2a, the second return direction side contact surface 81a is shown in FIGS. As shown in FIG. 5, the second portion is formed so as to protrude toward the second cutting direction X2 with respect to the adjacent portion 85 adjacent to the extending direction L.

図14に示すように、第二戻り方向側当接面81aは、延在方向Lの長さが剥離対象領域2aの延在方向Lの長さ以下に設定され、本実施形態では、第二切削方向側当接面62aの延在方向Lの長さは、上述した第二切削方向側当接面62aと同様、剥離対象領域2aの延在方向Lの長さより予め定められた量だけ短い値に設定されている。また、第二戻り方向側当接面81aは、延在方向Lに隣接する隣接部85に対する第二切削方向X2側への突出量ΔQ(図16参照)が、第一切削部材30による線材2の切削厚さ以上に設定され、本実施形態では、上述した第二切削方向側当接面62aの突出量ΔPと同様、突出量ΔQは、第一切削部材30による線材2の設計上の切削厚さに予め定められた量を加算した値に設定されている。よって、本実施形態では、設計上、図14及び図16に示すように、第二戻り方向側当接部材80における第二戻り方向側当接面81aのみが、線材2(剥離対象領域2a)に対して第二戻り方向Y2側から当接する。   As shown in FIG. 14, the second return direction contact surface 81a is set such that the length in the extending direction L is equal to or shorter than the length in the extending direction L of the separation target region 2a. The length in the extending direction L of the cutting direction side contact surface 62a is shorter than the length in the extending direction L of the separation target region 2a by a predetermined amount, like the second cutting direction side contact surface 62a. Is set to a value. Further, the second return direction side contact surface 81a has a protrusion amount ΔQ (see FIG. 16) in the second cutting direction X2 side with respect to the adjacent portion 85 adjacent to the extending direction L so that the wire 2 by the first cutting member 30 In the present embodiment, the projection amount ΔQ is the design cutting of the wire 2 by the first cutting member 30 in the same manner as the projection amount ΔP of the second cutting direction side contact surface 62a described above. It is set to a value obtained by adding a predetermined amount to the thickness. Therefore, in the present embodiment, as shown in FIGS. 14 and 16, only the second return direction side contact surface 81 a of the second return direction side contact member 80 is the wire 2 (peeling target region 2 a). Against the second return direction Y2 side.

3−3.往復動作機構の構成
次に、線材移動規制機構が備える、切削方向側当接部材50,60及び戻り方向側当接部材70,80のそれぞれを往復動作させるための往復動作機構について説明する。切削方向側当接部材50,60及び戻り方向側当接部材70,80のそれぞれは、剥離対象領域2aの移動を規制する規制位置と、剥離対象領域2aの移動を規制しない(すなわち許容する)非規制位置と、の間を径方向に沿って往復動作するように構成されている。なお、規制位置及び非規制位置のそれぞれは、第一切削方向側当接部材50、第二切削方向側当接部材60、第一戻り方向側当接部材70、及び第二戻り方向側当接部材80のそれぞれについて個別に設定される。
3-3. Structure of reciprocating mechanism
Next, a reciprocating operation mechanism for reciprocating each of the cutting direction side contact members 50 and 60 and the return direction side contact members 70 and 80 provided in the wire rod movement restriction mechanism will be described. Each of the cutting direction side contact members 50 and 60 and the return direction side contact members 70 and 80 does not restrict (i.e., allows) the restriction position for restricting the movement of the separation target region 2a and the movement of the separation target region 2a. It is configured to reciprocate along the radial direction between the non-regulating position. Each of the restriction position and the non-regulation position includes a first cutting direction side contact member 50, a second cutting direction side contact member 60, a first return direction side contact member 70, and a second return direction side contact. Each of the members 80 is set individually.

図7、図9、及び図11は、第一切削方向側当接部材50がその規制位置に位置するとともに、第一戻り方向側当接部材70がその規制位置に位置する状態を示している。また、図13、図15、及び図17は、第二切削方向側当接部材60がその規制位置に位置するとともに、第二戻り方向側当接部材80がその規制位置に位置する状態を示している。これらの図から明らかなように、切削方向側当接部材50,60についての規制位置は、当該切削方向側当接部材50,60(具体的には、切削方向側当接面52a,62a)が剥離対象領域2aに対して切削方向X1,X2側から当接する位置である。また、戻り方向側当接部材70,80についての規制位置は、当該戻り方向側当接部材70,80(具体的には、戻り方向側当接面71a,81a)が剥離対象領域2aに対して戻り方向Y1,Y2側から当接する位置である。   7, 9, and 11 illustrate a state in which the first cutting direction side contact member 50 is located at the restriction position and the first return direction side contact member 70 is located at the restriction position. . 13, FIG. 15, and FIG. 17 show a state in which the second cutting direction side contact member 60 is located at the restriction position and the second return direction side contact member 80 is located at the restriction position. ing. As is clear from these drawings, the restricting positions for the cutting direction side contact members 50 and 60 are the cutting direction side contact members 50 and 60 (specifically, the cutting direction side contact surfaces 52a and 62a). Is a position in contact with the separation target region 2a from the cutting direction X1, X2 side. Further, the restriction positions for the return direction contact members 70 and 80 are such that the return direction contact members 70 and 80 (specifically, the return direction contact surfaces 71a and 81a) are separated from the separation target region 2a. In this way, the position is abutted from the return direction Y1, Y2 side.

また、図1及び図2は、第一切削方向側当接部材50、第二切削方向側当接部材60、第一戻り方向側当接部材70、及び第二戻り方向側当接部材80の全てが非規制位置に位置する状態を示している。なお、第一切削方向側当接部材50及び第一戻り方向側当接部材70のそれぞれの非規制位置は、図13に示すように、第二切削部材40、第二切削方向側当接部材60、及び第二戻り方向側当接部材80のそれぞれの往復動作のために必要な空間から第一往復動作方向A1(図2参照)に離間した位置に設定されている。また、第二切削方向側当接部材60及び第二戻り方向側当接部材80のそれぞれの非規制位置は、図7に示すように、第一切削部材30、第一切削方向側当接部材50、及び第一戻り方向側当接部材70のそれぞれの往復動作のために必要な空間から第二往復動作方向A2(図2参照)に離間した位置に設定されている。   1 and 2 show the first cutting direction side contact member 50, the second cutting direction side contact member 60, the first return direction side contact member 70, and the second return direction side contact member 80. The state where all are located in the non-restricted position is shown. Note that the non-regulating positions of the first cutting direction side contact member 50 and the first return direction side contact member 70 are the second cutting member 40 and the second cutting direction side contact member, as shown in FIG. 60 and the second return direction side contact member 80 are set at positions separated from the spaces necessary for the reciprocating motion in the first reciprocating motion direction A1 (see FIG. 2). Further, the non-regulating positions of the second cutting direction side contact member 60 and the second return direction side contact member 80 are the first cutting member 30 and the first cutting direction side contact member, as shown in FIG. 50 and the space required for the reciprocating motion of the first return direction side contact member 70 are set at positions separated from each other in the second reciprocating motion direction A2 (see FIG. 2).

本実施形態では、線材移動規制機構10bは、上述した切削駆動機構10aと一体的に形成されており、切削駆動機構10aと同様、カム機構として構成されている。具体的には、図1に示すように、線材移動規制機構10bは、切削駆動機構10aを構成する第一回転体11に加えて、第二カム溝92を有するとともに延在方向Lを回転軸として回転可能な第二回転体12を備えた機構とされている。そして、本実施形態では、以下に説明するように、第一回転体11の回転位置に応じて、第一戻り方向側当接部材70の径方向の位置と第二戻り方向側当接部材80の径方向の位置とが定まり、第二回転体12の回転位置に応じて、第一切削方向側当接部材50の径方向の位置と第二切削方向側当接部材60の径方向の位置とが定まるように構成されている。   In the present embodiment, the wire movement restriction mechanism 10b is formed integrally with the above-described cutting drive mechanism 10a, and is configured as a cam mechanism similarly to the cutting drive mechanism 10a. Specifically, as shown in FIG. 1, the wire rod movement restricting mechanism 10 b includes a second cam groove 92 in addition to the first rotating body 11 that constitutes the cutting drive mechanism 10 a, and the extending direction L is the rotation axis. It is set as the mechanism provided with the 2nd rotary body 12 which can rotate. In the present embodiment, as described below, the radial position of the first return direction side contact member 70 and the second return direction side contact member 80 according to the rotational position of the first rotating body 11. The radial position of the first cutting direction side contact member 50 and the radial position of the second cutting direction side contact member 60 are determined according to the rotational position of the second rotating body 12. It is configured to be determined.

第一戻り方向側当接部材70は、図1及び図2に示すように、第一可動部材14aの径方向の内側の端部に取り付けられている。具体的には、図8及び図9に示すように、第一戻り方向側当接部材70は、第一連結部材16aを介して第一可動部材14aに取り付けられており、第一連結部材16aは、第一可動部材14aに対して径方向に相対移動可能に構成されている。また、第一連結部材16aは、付勢部材(図示せず)により第一切削方向X1側に付勢されている。   As shown in FIGS. 1 and 2, the first return direction contact member 70 is attached to the radially inner end of the first movable member 14a. Specifically, as shown in FIGS. 8 and 9, the first return direction side contact member 70 is attached to the first movable member 14a via the first connecting member 16a, and the first connecting member 16a. Is configured to be movable relative to the first movable member 14a in the radial direction. The first connecting member 16a is urged toward the first cutting direction X1 by an urging member (not shown).

第一戻り方向側当接部材70は、第一切削部材30が切削動作を行う際に、第一戻り方向側当接面71aが剥離対象領域2aに当接する(図8、図10参照)までは、当該第一切削部材30とともに第一切削方向X1側に移動する。なお、本実施形態では、図2に示すように、第一切削部材30が戻り方向側に位置するとともに第一戻り方向側当接部材70が非規制位置に位置する状態においても、第一切削部材30の先端部(第一切削方向X1側の部分)が第一戻り方向側当接部材70と延在方向Lに見て重なる位置に配置されるように構成されている。   When the first cutting member 30 performs the cutting operation, the first return direction side contact member 70 is in contact with the first return direction side contact surface 71a in contact with the separation target region 2a (see FIGS. 8 and 10). Moves along with the first cutting member 30 to the first cutting direction X1 side. In the present embodiment, as shown in FIG. 2, the first cutting member 30 is located on the return direction side and the first return direction side contact member 70 is located on the non-restricted position. The distal end portion (the portion on the first cutting direction X1 side) of the member 30 is configured to be disposed at a position overlapping the first return direction side contact member 70 in the extending direction L.

図8及び図10に示すように、第一切削部材30の切削動作に伴い第一戻り方向側当接面71aが剥離対象領域2aに当接した時点では、第一切削隙間32は剥離対象領域2aより第一戻り方向Y1側に位置する。また、詳細は後述するが、第一戻り方向側当接面71aが剥離対象領域2aに当接する時点と同時又はそれより前の時点で、第一切削方向側当接面52aが剥離対象領域2aに当接するように構成されている。よって、第一戻り方向側当接面71aが剥離対象領域2aに当接した後に引き続き行われる第一切削部材30の切削動作では、図9に示すように、第一切削部材30及び第一可動部材14aのみが第一切削方向X1側に移動し、第一戻り方向側当接部材70は、剥離対象領域2aを介して第一切削方向側当接部材50から受ける抗力と、上記付勢部材による付勢力とにより、径方向の位置が図8に示す位置(すなわち、規制位置)に維持される。この際、剥離対象領域2aは、上記付勢力に応じた力により第一往復動作方向A1の両側から保持されるため、第一往復動作方向A1に加えて第一往復動作方向A1に直交する方向(例えば延在方向L)における剥離対象領域2aの移動が規制される。   As shown in FIGS. 8 and 10, when the first return direction contact surface 71 a comes into contact with the separation target region 2 a in accordance with the cutting operation of the first cutting member 30, the first cutting gap 32 is separated from the separation target region. It is located on the first return direction Y1 side from 2a. Moreover, although mentioned later for details, the 1st cutting direction side contact surface 52a is the peeling object area | region 2a simultaneously with the time of the 1st return direction side contact surface 71a contact | abutting to the peeling object area | region 2a, or the time before it. It is comprised so that it may contact | abut. Therefore, in the cutting operation of the first cutting member 30 performed after the first return direction side contact surface 71a contacts the separation target region 2a, as shown in FIG. 9, the first cutting member 30 and the first movable member are moved. Only the member 14a moves to the first cutting direction X1 side, and the first return direction side contact member 70 receives the drag force received from the first cutting direction side contact member 50 via the separation target region 2a and the biasing member. Due to the urging force, the radial position is maintained at the position shown in FIG. At this time, since the separation target area 2a is held from both sides of the first reciprocating motion direction A1 by a force according to the urging force, a direction orthogonal to the first reciprocating motion direction A1 in addition to the first reciprocating motion direction A1. The movement of the separation target region 2a in the (e.g., extending direction L) is restricted.

また、第一切削部材30が戻し動作を行う際には、第一切削隙間32が剥離対象領域2aより第一戻り方向Y1側の位置に戻るまでの間は、図12に示すように、第一戻り方向側当接部材70の径方向位置は、上記付勢部材による付勢力により規制位置に維持される。そして、図12に示す状態から引き続き行われる第一切削部材30の戻し動作では、第一戻り方向側当接部材70が第一切削部材30とともに第一戻り方向Y1側に移動することで第一戻り方向側当接面71aが剥離対象領域2aから離間し、第一戻り方向側当接部材70は、図2に示す非規制位置に戻される。なお、詳細は後述するが、第一戻り方向側当接面71aが剥離対象領域2aから離間する時点と同時又はそれより後の時点で、第一切削方向側当接面52aが剥離対象領域2aから離間するように構成されている。よって、本実施形態では、剥離対象領域2aが第一切削隙間32に収まっている間、第一戻り方向側当接部材70と第一切削方向側当接部材50とにより剥離対象領域2aが保持される構成となっている。   In addition, when the first cutting member 30 performs the returning operation, the first cutting gap 32 is returned to the position on the first return direction Y1 side from the separation target region 2a as shown in FIG. The radial direction position of the one-return-direction-side contact member 70 is maintained at the restricted position by the urging force of the urging member. Then, in the return operation of the first cutting member 30 continued from the state shown in FIG. 12, the first return direction side contact member 70 moves to the first return direction Y1 side together with the first cutting member 30. The return direction contact surface 71a is separated from the separation target region 2a, and the first return direction contact member 70 is returned to the non-restricted position shown in FIG. In addition, although mentioned later for details, the 1st cutting direction side contact surface 52a is the peeling object area | region 2a at the time of the 1st return direction side contact surface 71a separating from the peeling object area | region 2a, or the time after it. It is comprised so that it may space apart from. Therefore, in this embodiment, while the separation target region 2a is within the first cutting gap 32, the separation target region 2a is held by the first return direction contact member 70 and the first cutting direction contact member 50. It becomes the composition which is done.

第二戻り方向側当接部材80は、図1及び図2に示すように、第二可動部材14bの径方向の内側の端部に取り付けられている。具体的には、図13及び図14に示すように、第二戻り方向側当接部材80は、第二連結部材16bを介して第二可動部材14bに取り付けられており、第二連結部材16bは、第二可動部材14bに対して径方向に相対移動可能に構成されている。また、第二連結部材16bは、付勢部材(図示せず)により第二切削方向X2側に付勢されている。   As shown in FIGS. 1 and 2, the second return direction contact member 80 is attached to the radially inner end of the second movable member 14 b. Specifically, as shown in FIGS. 13 and 14, the second return direction contact member 80 is attached to the second movable member 14b via the second connecting member 16b, and the second connecting member 16b. Is configured to be relatively movable in the radial direction with respect to the second movable member 14b. The second connecting member 16b is urged toward the second cutting direction X2 by an urging member (not shown).

第二戻り方向側当接部材80は、第一切削部材30、第一切削隙間32、第一戻り方向側当接面71a、第一切削方向側当接面52a、第一往復動作方向A1、第一切削方向X1、及び第一戻り方向Y1が、それぞれ、第二切削部材40、第二切削隙間42、第二戻り方向側当接面81a、第二切削方向側当接面62a、第二往復動作方向A2、第二切削方向X2、及び第二戻り方向Y2に置き換わる点を除いて、第一戻り方向側当接部材70と同様に動作する。すなわち、第二戻り方向側当接部材80は、第二切削部材40の切削動作時には、第二戻り方向側当接面81aが剥離対象領域2aに当接するまでは、第二切削部材40とともに第二切削方向X2側に移動する(図14及び図16参照)。また、第二戻り方向側当接部材80は、第二切削部材40の戻し動作時には、第二切削隙間42が剥離対象領域2aより第二戻り方向Y2側の位置に戻った後に(図18参照)、第二切削部材40とともに第二戻り方向Y2側に移動する。そして、本実施形態では、剥離対象領域2aが第二切削隙間42に収まっている間、第二戻り方向側当接部材80と第二切削方向側当接部材60とにより剥離対象領域2aが保持される構成となっている。   The second return direction side contact member 80 includes a first cutting member 30, a first cutting gap 32, a first return direction side contact surface 71a, a first cutting direction side contact surface 52a, a first reciprocating operation direction A1, The first cutting direction X1 and the first return direction Y1 are respectively the second cutting member 40, the second cutting gap 42, the second return direction contact surface 81a, the second cutting direction contact surface 62a, and the second. The operation is the same as that of the first return direction contact member 70 except that the reciprocation direction A2, the second cutting direction X2, and the second return direction Y2 are replaced. That is, the second return direction side contact member 80 is moved together with the second cutting member 40 until the second return direction side contact surface 81a contacts the separation target region 2a during the cutting operation of the second cutting member 40. It moves to the two cutting directions X2 side (refer to Drawing 14 and Drawing 16). Further, the second return direction contact member 80 returns the second cutting gap 42 to the second return direction Y2 side from the separation target region 2a during the return operation of the second cutting member 40 (see FIG. 18). ), And moves to the second return direction Y2 side together with the second cutting member 40. In this embodiment, while the separation target region 2a is within the second cutting gap 42, the separation target region 2a is held by the second return direction side contact member 80 and the second cutting direction side contact member 60. It becomes the composition which is done.

第一切削方向側当接部材50と第二切削方向側当接部材60とは、第二回転体12の回転に伴い往復動作する。第二回転体12は、図1に示すように、第一回転体11と同様、厚さ方向が延在方向Lに平行な円環板状に形成されているとともに、板状部材17に対して回転可能に支持されている。本実施形態では、第二回転体12は、連結部材13により周方向の複数箇所で第一回転体11に固定されており、第一回転体11と一体回転するように構成されている。すなわち、第二回転体12は、第一回転体11を介して板状部材17に対して支持されており、第一回転体11を回転駆動する駆動機構(図示せず)により、第二回転体12の回転位置も制御される。   The first cutting direction side contact member 50 and the second cutting direction side contact member 60 reciprocate as the second rotating body 12 rotates. As shown in FIG. 1, the second rotating body 12 is formed in an annular plate shape whose thickness direction is parallel to the extending direction L, as in the case of the first rotating body 11. And is rotatably supported. In the present embodiment, the second rotating body 12 is fixed to the first rotating body 11 at a plurality of locations in the circumferential direction by the connecting member 13, and is configured to rotate integrally with the first rotating body 11. That is, the second rotator 12 is supported by the plate-like member 17 via the first rotator 11, and is rotated second by a drive mechanism (not shown) that rotationally drives the first rotator 11. The rotational position of the body 12 is also controlled.

第二カム溝92は、第二回転体12の延在方向Lにおける剥離対象領域2a側の板面(板状部材17側の面)に形成されている。第二カム溝92は、図2に示すように、第一カム溝91と同様、径方向の位置が周方向に沿って不均一に形成されており、具体的には、第一大径部91aに対応する第二大径部92aと、第一小径部91bに対応する第二小径部92bと、第一接続部91cに対応する第二接続部92cと、を有するように形成されている。なお、第二カム溝92の第二小径部92bは、第一カム溝91の第一小径部91bとは異なり円弧状に延びるように形成されており、当該第一小径部91bより周方向の広い範囲に亘って形成されている。そして、第二カム溝92により、第三可動部材14cと一体的に径方向に移動する第三被案内部材15cと、第四可動部材14dと一体的に径方向に移動する第四被案内部材15dとが案内される。   The second cam groove 92 is formed in the plate surface (surface on the plate-like member 17 side) on the separation target region 2 a side in the extending direction L of the second rotating body 12. As shown in FIG. 2, the second cam groove 92 is formed with a non-uniform radial position along the circumferential direction, specifically the first cam groove 91. The second large diameter portion 92a corresponding to 91a, the second small diameter portion 92b corresponding to the first small diameter portion 91b, and the second connection portion 92c corresponding to the first connection portion 91c are formed. . Unlike the first small-diameter portion 91b of the first cam groove 91, the second small-diameter portion 92b of the second cam groove 92 is formed to extend in an arc shape, and is more circumferential than the first small-diameter portion 91b. It is formed over a wide range. The second guided groove 15c moves in the radial direction integrally with the third movable member 14c and the fourth guided member moves in the radial direction integrally with the fourth movable member 14d by the second cam groove 92. 15d is guided.

第三可動部材14cの径方向内側の端部には、図1及び図2に示すように、第一切削方向側当接部材50が固定されている。そして、第二カム溝92の第二大径部92aの径方向位置は、図1及び図2に示すように、第三被案内部材15cが当該第二大径部92aにより案内される状態で第一切削方向側当接部材50が非規制位置に位置するように設定されている。また、第二カム溝92の第二小径部92bの径方向位置は、図7に示すように、第三被案内部材15cが当該第二小径部92bにより案内される状態で第一切削方向側当接部材50が規制位置に位置するように設定されている。よって、第一切削方向側当接部材50は、第二回転体12の回転に伴い、当該第一切削方向側当接部材50の規制位置と非規制位置との間を、径方向(具体的には第一往復動作方向A1)に沿って往復動作する。   As shown in FIGS. 1 and 2, a first cutting direction side contact member 50 is fixed to the radially inner end of the third movable member 14c. The radial position of the second large diameter portion 92a of the second cam groove 92 is such that the third guided member 15c is guided by the second large diameter portion 92a as shown in FIGS. The first cutting direction side contact member 50 is set so as to be positioned at the non-restricted position. Further, as shown in FIG. 7, the radial position of the second small diameter portion 92b of the second cam groove 92 is the first cutting direction side in a state where the third guided member 15c is guided by the second small diameter portion 92b. The contact member 50 is set so as to be positioned at the restriction position. Therefore, the first cutting direction side abutting member 50 has a radial direction (specifically, between the restricted position and the non-regulated position of the first cutting direction side abutting member 50 as the second rotating body 12 rotates. Is reciprocated along the first reciprocating direction A1).

上記のように、第一切削方向側当接部材50は、第三被案内部材15cが第二小径部92bにより案内される状態で、規制位置に位置する。すなわち、第一戻り方向側当接部材70が規制位置に位置する期間に対する、第一切削方向側当接部材50が規制位置に位置する期間の時間的関係は、第二カム溝92の形状により設定することができる。そして、第一戻り方向側当接面71aが剥離対象領域2aに当接する時点と同時又はそれより前の時点(本例では後者)で、第一切削方向側当接面52aが剥離対象領域2aに当接し、第一戻り方向側当接面71aが剥離対象領域2aから離間する時点と同時又はそれより後の時点(本例では後者)で、第一切削方向側当接面52aが剥離対象領域2aから離間するように、第二カム溝92の形状(具体的には、第二小径部92bの周方向位置及び周方向長さ)が設定されている。   As described above, the first cutting direction side contact member 50 is located at the restriction position in a state where the third guided member 15c is guided by the second small diameter portion 92b. That is, the time relationship of the period in which the first cutting direction side contact member 50 is located at the restriction position with respect to the period in which the first return direction contact member 70 is located at the restriction position depends on the shape of the second cam groove 92. Can be set. The first cutting direction side contact surface 52a is separated from the separation target region 2a at the same time as the time when the first return direction contact surface 71a contacts the separation target region 2a or at a time before that (the latter in this example). The first cutting direction side contact surface 52a is to be peeled off at the same time as or after the time when the first return direction side contact surface 71a is separated from the separation target region 2a (the latter in this example). The shape of the second cam groove 92 (specifically, the circumferential position and the circumferential length of the second small diameter portion 92b) is set so as to be separated from the region 2a.

第四可動部材14dは、周方向の配設位置が異なる点を除いて第三可動部材14cと同様に構成されている。第四可動部材14dの径方向内側の端部には、図1及び図2に示すように、第二切削方向側当接部材60が固定されている。第二切削方向側当接部材60は、第二回転体12の回転に伴い、当該第二切削方向側当接部材60の規制位置と非規制位置との間を、径方向(具体的には第二往復動作方向A2)に沿って往復動作する。そして、第二戻り方向側当接面81aが剥離対象領域2aに当接する時点と同時又はそれより前の時点(本例では後者)で、第二切削方向側当接面62aが剥離対象領域2aに当接し、第二戻り方向側当接面81aが剥離対象領域2aから離間する時点と同時又はそれより後の時点(本例では後者)で、第二切削方向側当接面62aが剥離対象領域2aから離間するように構成されている。   The fourth movable member 14d is configured in the same manner as the third movable member 14c except that the arrangement position in the circumferential direction is different. As shown in FIGS. 1 and 2, a second cutting direction side contact member 60 is fixed to the radially inner end of the fourth movable member 14d. As the second rotating body 12 rotates, the second cutting direction side abutting member 60 has a radial direction (specifically, between the regulated position and the non-regulated position of the second cutting direction side abutting member 60). It reciprocates along the second reciprocating direction A2). The second cutting direction side contact surface 62a is separated from the separation target region 2a at the same time as or before the second return direction contact surface 81a contacts the separation target region 2a (the latter in this example). The second cutting direction side contact surface 62a is peeled off at the same time as or later than the time point when the second return direction contact surface 81a is separated from the separation target region 2a (the latter in this example). It is comprised so that it may space apart from the area | region 2a.

第二剥離工程P20は、図19に示すように、第二保持工程P21、第二切削工程P22、第二戻し工程P23、及び第二保持解除工程P24を順に実行する工程である。第二保持工程P21は、第二切削部材40を切削動作させることにより当該部材を第二切削方向X2側に移動させて、図1及び図2と同様の状態から図14及び図16に示す状態に移行させる工程である。なお、図16に示すように、第二切削方向側当接部材60は、第二戻り方向Y2側の端面60aが、第二切削方向側当接面62aに当接する状態の線材2の第二戻り方向Y2側の端面より第二切削方向X2側に位置するように形成されている。第二切削工程P22は、第二保持工程P21の実行完了後も引き続き第二切削部材40を切削動作させ、図14及び図16に示す状態から図13、図15、及び図17に示す状態に移行させる工程である。これにより、剥離対象領域2aにおける第二線材幅方向W2の両側の側面部の被覆層3が削り取られる。このように、第二切削部材40を切削動作させることで、第二保持工程P21及び第二切削工程P22が順に実行される。
4-3. Second Peeling Step The second peeling step P20 is a step of sequentially executing a second holding step P21, a second cutting step P22, a second returning step P23, and a second holding releasing step P24, as shown in FIG. . In the second holding step P21, the second cutting member 40 is moved by moving the second cutting member 40 to the second cutting direction X2, and the state shown in FIGS. 14 and 16 is changed from the state similar to FIGS. It is the process of making it transfer.

It is the process of making it transfer. In the second holding release process P24, the second cutting member 40 is continuously returned even after the execution of the second return process P23 is completed, and the state shown in FIG. 1 and FIG. 2 from the state shown in FIG. The shape of is different from that in FIGS. 1 and 2). That is, by returning the second cutting member 40, the second return step P23 and the second holding release step P24 are sequentially executed. Note that, during the period from the completion of execution of the second holding step P21 to the start of execution of the second holding release step P24, the separation target region 2a is in contact with the second return direction side contact member 80 and the second cutting direction side.

同一の線材2に未だ被覆層3を剥離していない剥離対象領域2aがある場合には、再度、線材搬送工程P01からの各処理が実行される。また、詳細は省略するが、線材2の外周における角部(線材2の長方形状の断面における頂点に対応する部分)に円弧状部や面取り部が形成されていること等により、当該各部に被覆層3が残る場合には、残っている被覆層3を更に別の工程により剥離する構成とすることができる。   When there is a separation target region 2a in which the coating layer 3 is not yet peeled on the same wire 2, each process from the wire transport step P01 is performed again. In addition, although details are omitted, the respective parts are covered by forming an arcuate part or a chamfered part at the corner part (the part corresponding to the apex in the rectangular cross section of the wire 2) on the outer periphery of the wire 2 etc. When the layer 3 remains, it can be set as the structure which peels the remaining coating layer 3 by another process.

最後に、本発明に係る剥離装置の、その他の実施形態について説明する。なお、以下のそれぞれの実施形態で開示される構成は、矛盾が生じない限り、他の実施形態で開示される構成と組み合わせて適用することが可能である。
5. Other Embodiments Lastly, other embodiments of the peeling apparatus according to the present invention will be described. Note that the configurations disclosed in the following embodiments can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction arises.

(1)上記の実施形態では、切削駆動機構10a及び線材移動規制機構10bの双方が、カム機構として構成されている場合を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、切削駆動機構10a及び線材移動規制機構10bの少なくとも一方が、カム機構とは異なる機構(例えばシリンダ機構等)により切削部材30,40又は当接部材50,60,70,80を往復動作させる構成とすることもできる。また、上記の実施形態では、切削部材30,40と戻り方向側当接部材70,80とが同一の可動部材14a,14bに取り付けられた構成を例として説明したが、切削部材30,40と戻り方向側当接部材70,80とが互いに別の可動部材に取り付けられる構成とすることもできる。この場合、例えば、戻り方向側当接部材70,80のための専用のカム溝を備える構成とすることができる。このような専用のカム溝は、例えば、第一回転体11における第一カム溝91とは異なる径方向位置や、第二回転体12における第二カム溝92とは異なる径方向位置に設けることができる。また、戻り方向側当接部材70,80が可動部材に対して径方向に移動不能に固定される構成とすることができ、この場合には、線材2の損傷を抑制すべく、切削方向側当接部材50,60が可動部材に対して径方向に移動可能に取り付けられる構成とすると好適である。 (1) In the above-described embodiment, the case where both the cutting drive mechanism 10a and the wire movement restriction mechanism 10b are configured as cam mechanisms has been described as an example. However, the embodiment of the present invention is not limited to this, and at least one of the cutting drive mechanism 10a and the wire movement restriction mechanism 10b is cut by the cutting members 30 and 40 by a mechanism (for example, a cylinder mechanism or the like) different from the cam mechanism. Alternatively, the contact members 50, 60, 70, and 80 can be configured to reciprocate. In the above embodiment, the configuration in which the cutting members 30 and 40 and the return direction contact members 70 and 80 are attached to the same movable members 14a and 14b has been described as an example. The return direction side contact members 70 and 80 may be attached to different movable members. In this case, for example, it can be set as the structure provided with the cam groove for exclusive use for the return direction side contact members 70 and 80. FIG. For example, such a dedicated cam groove is provided at a radial position different from the first cam groove 91 in the first rotating body 11 or at a radial position different from the second cam groove 92 in the second rotating body 12. Can do. Further, the return direction side contact members 70 and 80 can be fixed so as to be immovable in the radial direction with respect to the movable member. In this case, in order to suppress damage to the wire 2, It is preferable that the contact members 50 and 60 are attached to the movable member so as to be movable in the radial direction.

(2)上記の実施形態では、第一切削方向側当接部材50及び第二切削方向側当接部材60の双方が、線材幅方向W1,W2における線材2の中央部に対して両側に傾斜面53a,63aを備えた構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、第一切削方向側当接部材50及び第二切削方向側当接部材60の少なくとも一方が、線材幅方向W1,W2における線材2の中央部に対して片側のみに傾斜面53a,63aを備える構成とすることができる。また、第一切削方向側当接部材50及び第二切削方向側当接部材60の少なくとも一方が、傾斜面53a,63aを備えない構成とすることもできる。このような場合において、鉛直方向の上側を向く傾斜面のみが備えられる構成とすることができる。例えば、図2における上下方向が鉛直方向と一致する場合には、第一切削方向側当接部材50が、第一線材幅方向W1における線材2の中央部に対して両側に第一傾斜面53aを備え、第二切削方向側当接部材60が、第二線材幅方向W2における線材2の中央部に対して鉛直方向上方側(図2における上側)のみに第二傾斜面63aを備える構成とすることができる。 (2) In the above embodiment, both the first cutting direction side contact member 50 and the second cutting direction side contact member 60 are inclined on both sides with respect to the central portion of the wire 2 in the wire width direction W1, W2. The configuration provided with the surfaces 53a and 63a has been described as an example. However, the embodiment of the present invention is not limited to this, and at least one of the first cutting direction side contact member 50 and the second cutting direction side contact member 60 is the wire 2 in the wire width direction W1, W2. It can be set as the structure provided with the inclined surfaces 53a and 63a only on one side with respect to the center part. Further, at least one of the first cutting direction side contact member 50 and the second cutting direction side contact member 60 may be configured not to include the inclined surfaces 53a and 63a. In such a case, it can be set as the structure provided only with the inclined surface which faces the upper side of a perpendicular direction. For example, when the vertical direction in FIG. 2 coincides with the vertical direction, the first cutting direction side contact member 50 has the first inclined surfaces 53a on both sides with respect to the central portion of the wire 2 in the first wire width direction W1. And the second cutting direction side contact member 60 includes the second inclined surface 63a only on the upper side in the vertical direction (upper side in FIG. 2) with respect to the central portion of the wire 2 in the second wire width direction W2. can do.

(3)上記の実施形態では、第一刃幅ΔT1と第二刃幅ΔT2とが同じ値とされた構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、線材2の用途等によっては、第一刃幅ΔT1と第二刃幅ΔT2とが互いに異なる値に設定される構成とすることも可能である。 (3) In the above embodiment, the configuration in which the first blade width ΔT1 and the second blade width ΔT2 have the same value has been described as an example. However, the embodiment of the present invention is not limited to this, and the first blade width ΔT1 and the second blade width ΔT2 may be set to different values depending on the application of the wire 2 or the like. Is possible.

(4)上記の実施形態では、第一切削方向側当接面52a及び第二切削方向側当接面62aの内の第二切削方向側当接面62aのみが、延在方向Lに隣接する隣接部に対して戻り方向Y1,Y2側に突出するように形成されるとともに、第一戻り方向側当接面71a及び第二戻り方向側当接面81aの内の第二戻り方向側当接面81aのみが、延在方向Lに隣接する隣接部に対して切削方向X1,X2側に突出するように形成されている構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、第一切削方向側当接面52aが延在方向Lに隣接する隣接部に対して第一戻り方向Y1側に突出するように形成された構成とすることができる。この場合、第一切削方向側当接面52aの延在方向Lの長さは、当然ながら、剥離対象領域2aの延在方向Lの長さとは無関係に設定することができ、第二切削方向側当接面62aとは異なり、延在方向Lの長さを剥離対象領域2aより大きくすることも可能である。また、第一切削方向側当接面52aの延在方向Lに隣接する隣接部に対する第一戻り方向Y1側への突出量は、当然ながら、線材2の切削厚さとは無関係に設定することができる。また、第一戻り方向側当接面71aが延在方向Lに隣接する隣接部に対して第一切削方向X1側に突出するように形成された構成とすることもできる。この場合、第一戻り方向側当接面71aの延在方向Lの長さは、当然ながら、剥離対象領域2aの延在方向Lの長さとは無関係に設定することができ、第二戻り方向側当接面81aとは異なり、延在方向Lの長さを剥離対象領域2aより大きくすることも可能である。また、第一戻り方向側当接面71aの延在方向Lに隣接する隣接部に対する第一切削方向X1側への突出量は、当然ながら、線材2の切削厚さとは無関係に設定することができる。 (4) In the above embodiment, only the second cutting direction side contact surface 62a of the first cutting direction side contact surface 52a and the second cutting direction side contact surface 62a is adjacent to the extending direction L. It is formed so as to protrude toward the return direction Y1, Y2 with respect to the adjacent portion, and the second return direction side contact of the first return direction side contact surface 71a and the second return direction side contact surface 81a. The configuration in which only the surface 81a is formed so as to protrude toward the cutting directions X1 and X2 with respect to the adjacent portion adjacent to the extending direction L has been described as an example. However, the embodiment of the present invention is not limited to this, and the first cutting direction side contact surface 52a protrudes toward the first return direction Y1 side with respect to the adjacent portion adjacent to the extending direction L. It can be set as the formed structure. In this case, the length in the extending direction L of the first cutting direction side contact surface 52a can be set independently of the length in the extending direction L of the separation target region 2a, and the second cutting direction Unlike the side contact surface 62a, it is possible to make the length in the extending direction L larger than the separation target region 2a. Moreover, naturally the protrusion amount to the 1st return direction Y1 side with respect to the adjacent part adjacent to the extension direction L of the 1st cutting direction side contact surface 52a can be set irrespective of the cutting thickness of the wire 2. FIG. it can. Moreover, it can also be set as the structure formed so that the 1st return direction side contact surface 71a might protrude in the 1st cutting direction X1 side with respect to the adjacent part adjacent to the extending direction L. FIG. In this case, the length in the extending direction L of the first return direction side contact surface 71a can of course be set regardless of the length in the extending direction L of the separation target region 2a. Unlike the side contact surface 81a, the length in the extending direction L can be made larger than the separation target region 2a. Moreover, naturally the protrusion amount to the 1st cutting direction X1 side with respect to the adjacent part adjacent to the extension direction L of the 1st return direction side contact surface 71a can be set irrespective of the cutting thickness of the wire 2. FIG. it can.

(5)上記の実施形態では、第二切削方向側当接面62aの延在方向Lに隣接する隣接部65に対する第二戻り方向Y2側への突出量ΔPが、第一切削部材30による線材2の切削厚さ以上に設定される構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、突出量ΔPが第一切削部材30による線材2の切削厚さより小さい値に設定される構成とすることもできる。この場合、上記の実施形態とは異なり、設計上、隣接部65を含む第二移動規制溝66の底面が、線材2に対して第二切削方向X2側から当接する構成となり、第二切削部材40の切削動作に伴い剥離対象領域2aが第二切削方向X2側に弾性変形した際に、第二切削方向側当接面62aが当該剥離対象領域2aに対して当接する構成となる。この場合、線材2に許容される変形量に応じて突出量ΔPを設定することができる。 (5) In the above embodiment, the protrusion amount ΔP toward the second return direction Y2 side with respect to the adjacent portion 65 adjacent to the extending direction L of the second cutting direction side contact surface 62a is the wire rod by the first cutting member 30. The configuration set to be equal to or greater than the cutting thickness of 2 has been described as an example. However, the embodiment of the present invention is not limited to this, and the protrusion amount ΔP may be set to a value smaller than the cutting thickness of the wire 2 by the first cutting member 30. In this case, unlike the above-described embodiment, the bottom surface of the second movement restriction groove 66 including the adjacent portion 65 is configured to come into contact with the wire 2 from the second cutting direction X2 side. When the separation target region 2a is elastically deformed in the second cutting direction X2 side with the cutting operation of 40, the second cutting direction side contact surface 62a comes into contact with the separation target region 2a. In this case, the protrusion amount ΔP can be set according to the deformation amount allowed for the wire 2.

(6)上記の実施形態では、第二戻り方向側当接面81aの延在方向Lに隣接する隣接部85に対する第二切削方向X2側への突出量ΔQが、第一切削部材30による線材2の切削厚さ以上に設定される構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、突出量ΔQが第一切削部材30による線材2の切削厚さより小さい値に設定される構成とすることもできる。この場合、上記の実施形態とは異なり、設計上、隣接部85を含む第二当接部81の第二切削方向X2側の面が、線材2に対して第二戻り方向Y2側から当接する構成となり、第二切削部材40の戻し動作に伴い剥離対象領域2aが第二戻り方向Y2側に弾性変形した際に、第二戻り方向側当接面81aが当該剥離対象領域2aに対して当接する構成となる。この場合、線材2に許容される変形量に応じて突出量ΔQを設定することができる。 (6) In the above embodiment, the protrusion amount ΔQ to the second cutting direction X2 side with respect to the adjacent portion 85 adjacent to the extending direction L of the second return direction side contact surface 81a is the wire rod by the first cutting member 30. The configuration set to be equal to or greater than the cutting thickness of 2 has been described as an example. However, the embodiment of the present invention is not limited to this, and the protrusion amount ΔQ may be set to a value smaller than the cutting thickness of the wire 2 by the first cutting member 30. In this case, unlike the above-described embodiment, the surface on the second cutting direction X2 side of the second contact portion 81 including the adjacent portion 85 contacts the wire 2 from the second return direction Y2 side by design. When the separation target region 2a is elastically deformed in the second return direction Y2 side with the return operation of the second cutting member 40, the second return direction side contact surface 81a contacts the separation target region 2a. It becomes the composition which touches. In this case, the protrusion amount ΔQ can be set according to the deformation amount allowed for the wire 2.

However, the embodiment of the present invention is not limited to this, and the separation target region 2a abuts in the return direction side only during a part of the period while the separation target region 2a is within the cutting gaps 32 and 42. It can be set as the structure hold | maintained by member 70,80 and the cutting direction side contact member 50,60. Further, the separation target region 2a is not held by the return direction side contact members 70, 80 and the cutting direction side contact members 50, 60, that is, the return direction side contact members 70, 80 and the cutting direction side contact member. Each of 50 and 60 may be configured to abut on the separation target region 2a only in different periods. In these cases, when the cutting members 30 and 40 are moved to the cutting directions X1 and X2 in a state where the separation target region 2a is within the cutting gaps 32 and 42, at least the cutting direction side contact member 50, When the cutting members 30 and 40 are moved to the return direction Y1 and Y2 side in a state where 60 is in contact with the separation target region 2a and the separation target region 2a is within the cutting gaps 32 and 42, at least the return direction side It is preferable that the contact members 70 and 80 are configured to contact the separation target region 2a.

(8)上記の実施形態では、線材移動規制機構10bが、切削方向側当接部材50,60に加えて戻り方向側当接部材70,80を備えた構成を例として説明した。しかし、本発明の実施形態はこれに限定されるものではなく、線材移動規制機構10bが、切削方向側当接部材50,60のみを備え、剥離対象領域2aの切削方向X1,X2側への移動のみを規制する構成とすることもできる。 (8) In the above embodiment, the configuration in which the wire movement restriction mechanism 10b includes the return direction side contact members 70 and 80 in addition to the cutting direction side contact members 50 and 60 has been described as an example. However, the embodiment of the present invention is not limited to this, and the wire rod movement restriction mechanism 10b includes only the cutting direction side contact members 50 and 60, and the separation target region 2a toward the cutting direction X1 and X2 side. It can also be set as the structure which controls only a movement.

(9)その他の構成に関しても、本明細書において開示された実施形態は全ての点で例示であって、本発明の実施形態はこれに限定されない。すなわち、本願の特許請求の範囲に記載されていない構成に関しては、本発明の目的を逸脱しない範囲内で適宜改変することが可能である。 (9) Regarding other configurations as well, the embodiments disclosed herein are illustrative in all respects, and embodiments of the present invention are not limited thereto.
