Description

本発明は、回転電機のコイルなどに用いられる集合導線片の製造方法に関する。 The present invention relates to a method for manufacturing a collective lead wire piece used for a coil of a rotary electric machine or the like.

近年、電動車両などに搭載される回転電機に対しては、出力向上の要求が高まっており、回転電機のコイルには、占積率の向上が求められている。 In recent years, there has been an increasing demand for improved output of rotary electric machines mounted on electric vehicles and the like, and the coils of rotary electric machines are required to have an improved space factor.

一方で、回転電機のコイルの占積率が増大すると、放熱性が悪化する。また、コイルの占積率増大に伴い、コイルの断面積が大きくなると、コイルの表皮効果が悪化し、自コイルによる渦電流損が増大し、ロータのマグネットから受ける渦電流ブレーキ作用が生じる、等により、回転電機の効率が低下してしまう、という課題があった。 On the other hand, when the space factor of the coil of the rotary electric machine increases, the heat dissipation property deteriorates. In addition, when the cross-sectional area of the coil increases as the space factor of the coil increases, the skin effect of the coil deteriorates, the eddy current loss due to the own coil increases, and the eddy current braking action received from the rotor magnet occurs, etc. As a result, there is a problem that the efficiency of the rotary electric machine is lowered.

これらの課題を解決するために、例えば、特許文献１には、回転電機のコイル用の導線として、複数の素線を撚り合わせて構成された集合導体片を用いることが開示されている。 In order to solve these problems, for example, Patent Document 1 discloses that a collective conductor piece formed by twisting a plurality of strands is used as a conducting wire for a coil of a rotary electric machine.

特開２０１５－５０１４６号公報Japanese Unexamined Patent Publication No. 2015-50146

しかしながら、回転電機のコイル用の導線に、複数の素線を撚り合わせて構成された一般的な集合導体片を用いた場合、複数の集合導線片を曲げ成型等により同形状に成型する際に、折り曲げ部位における複数の素線の撚り合わせの配置及び形状は、集合導線片によってそれぞれ異なる。したがって、集合導体片の成型時において、折り曲げ部位に生じる応力分布が、集合導線片によってそれぞれ異なることとなる。 However, when a general collective conductor piece composed by twisting a plurality of strands is used as a lead wire for a coil of a rotary electric machine, when the plurality of collective lead wire pieces are molded into the same shape by bending or the like. , The arrangement and shape of the twisting of the plurality of strands at the bent portion differ depending on the collective conductor piece. Therefore, the stress distribution generated at the bent portion at the time of molding the collective conductor piece differs depending on the collective conductor piece.

このため、図１１Ａ及び図１１Ｂに示すように、複数の集合導線片１０Ａを同一プログラムで略Ｕ字状に成型しても、成型後の形状にばらつきが生じてしまう、という課題があった。 Therefore, as shown in FIGS. 11A and 11B, even if a plurality of collective conductor pieces 10A are molded into a substantially U shape by the same program, there is a problem that the shape after molding varies.

本発明は、成型後の形状のばらつきを低減することができる集合導線片の製造方法を提供する。 The present invention provides a method for manufacturing an aggregated conductor piece that can reduce variations in shape after molding.

以下、本発明の集合導線片の製造方法の各実施形態を、添付図面に基づいて説明する。 Hereinafter, embodiments of the method for manufacturing the collective conductor piece of the present invention will be described with reference to the accompanying drawings.

［第１実施形態］
先ず、本発明の第１実施形態の集合導線片１０の製造方法について図１～図８を参照しながら説明する。 [First Embodiment]
First, a method for manufacturing the collective conductor piece 10 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 8.

集合導線片１０は、長尺の集合導線１を切断することによって製造される。 The collective lead piece 10 is manufactured by cutting the long collective lead wire 1.

＜集合導線＞
図１に示すように、集合導線１は、断面略長方形状の平角線であり、複数の素線１００が一定の所定リード角θ及び一定の所定ピッチＰで撚り合わされて構成されている。集合導線１は、外周面が絶縁体１０１によって絶縁被覆されている。このとき、集合導線１は、絶縁被覆された状態で複数の素線１００が視認可能であることが好ましい。本明細書において、リード角とは、撚り合わされた素線１００と集合導線１の長さ方向との成す角度をいい、ピッチとは、複数の素線１００が撚り合わされた集合導線１の断面形状が同一となるまでの長さをいう。また、本明細書では、複数の素線１００が撚り合わされた集合導線１の断面形状が所定の断面形状を有する位置をピッチ開始位置ＰＳという。 <Aggregate conductor>
As shown in FIG. 1, the collective conductor 1 is a flat wire having a substantially rectangular cross section, and is configured by twisting a plurality of strands 100 at a constant predetermined lead angle θ and a constant predetermined pitch P. The outer peripheral surface of the collective conductor 1 is insulated and coated with an insulator 101. At this time, it is preferable that a plurality of strands 100 can be visually recognized as the collective conductor 1 in a state of being insulated and coated. In the present specification, the lead angle is the angle formed by the twisted strands 100 and the length direction of the collective conductor 1, and the pitch is the cross-sectional shape of the collective conductor 1 in which a plurality of strands 100 are twisted. Refers to the length until they are the same. Further, in the present specification, the position where the cross-sectional shape of the collective conductor 1 in which a plurality of strands 100 are twisted has a predetermined cross-sectional shape is referred to as a pitch start position PS.

図２に示すように、集合導線１の１つのピッチ内において異なる位置の断面形状は、それぞれ異なる。また、本実施形態では、集合導線１は、複数の素線１００が一定の所定リード角θ及び一定の所定ピッチＰで撚り合わされているので、集合導線１における複数の素線１００の配置及び形状は周期的に変化する。したがって、集合導線１の断面形状が同一形状の場合、集合導線１のピッチ開始位置ＰＳからの長さは同一となる。本明細書では、集合導線１のある位置における複数の素線１００の撚り合わせの配置及び形状を位相という。 As shown in FIG. 2, the cross-sectional shapes of different positions within one pitch of the collective conductor 1 are different. Further, in the present embodiment, since the plurality of strands 100 are twisted at a constant predetermined lead angle θ and a constant predetermined pitch P in the collective conductor 1, the arrangement and shape of the plurality of strands 100 in the collective conductor 1 Changes periodically. Therefore, when the cross-sectional shapes of the collective conductors 1 are the same, the lengths of the collective conductors 1 from the pitch start position PS are the same. In the present specification, the arrangement and shape of the twists of the plurality of strands 100 at a certain position of the collective conductor 1 is referred to as a phase.

図３に示すように、集合導線１は、平角線の１つの外周面（例えば上面）から見て、所定リード角θで略直線状に延びる複数の素線１００の隣接部ＰＬが形成されている。集合導線１の１つのピッチ内において異なる位置の隣接部ＰＬの配置は、それぞれ異なる。一方で、本実施形態では、集合導線１は、複数の素線１００が一定の所定リード角θ及び一定の所定ピッチＰで撚り合わされているので、隣接部ＰＬの配置が同一の場合、集合導線１のピッチ開始位置ＰＳからの長さは同一となる。 As shown in FIG. 3, the collective conductor 1 is formed with adjacent portions PL of a plurality of strands 100 extending substantially linearly at a predetermined lead angle θ when viewed from one outer peripheral surface (for example, the upper surface) of the flat wire. There is. The arrangement of adjacent portions PL at different positions within one pitch of the collective conductor 1 is different. On the other hand, in the present embodiment, since the plurality of strands 100 are twisted at a constant predetermined lead angle θ and a constant predetermined pitch P in the collective conductor 1, when the arrangement of the adjacent portions PL is the same, the collective conductor wire 1 The length from the pitch start position PS of 1 is the same.

＜加工装置＞
図４に示すように、加工装置２０は、集合導線１を曲げ成型及び切断し、曲げ成型された所定長さＬの集合導線片１０を製造するための装置である。 <Processing equipment>
As shown in FIG. 4, the processing apparatus 20 is an apparatus for bending and cutting the collective lead wire 1 to manufacture a bent and molded collective lead wire piece 10 having a predetermined length L.

加工装置２０は、ボビン３０等に巻かれた集合導線１を長さ方向に送り出す送出部２１と、集合導線１が貫通可能であり、集合導線１を保持する導線ガイド部２２と、導線ガイド部２２が固定され、集合導線１の長さ方向と略垂直な面に延びる取付パネル２３と、取付パネル２３に取り付けられ、集合導線１を曲げ成型するベンディング部２４と、取付パネル２３に取り付けられ、集合導線１を切断する切断部２５と、集合導線１の先端部１Ｆの断面形状を読み取る読取部２６と、不図示の位相差算出装置及び端部切断長さ算出装置と、を備える。 The processing device 20 includes a delivery unit 21 that sends out the collective lead wire 1 wound around the bobbin 30 or the like in the length direction, a lead wire guide section 22 that allows the collective lead wire 1 to pass through and holds the collective lead wire 1, and a lead wire guide section. 22 is fixed and is attached to a mounting panel 23 extending in a plane substantially perpendicular to the length direction of the collective lead wire 1, a bending portion 24 attached to the mounting panel 23 and bending and molding the collective lead wire 1, and a mounting panel 23. It includes a cutting unit 25 for cutting the collective lead wire 1, a reading unit 26 for reading the cross-sectional shape of the tip portion 1F of the collective lead wire 1, and a phase difference calculation device and an end cut length calculation device (not shown).

＜集合導線片の製造工程＞
集合導線１から集合導線片１０を製造する製造工程を、図５～図８を参照して説明する。 <Manufacturing process of collective conductor pieces>
The manufacturing process for manufacturing the collective lead wire piece 10 from the collective lead wire 1 will be described with reference to FIGS. 5 to 8.

図５に示すように、まず、読取工程Ｓ１１０を行う。読取工程Ｓ１１０では、集合導線１の先端部１Ｆの断面形状を読み取る。 As shown in FIG. 5, first, the reading step S110 is performed. In the reading step S110, the cross-sectional shape of the tip portion 1F of the collective conductor 1 is read.

具体的には、図６の（ａ）に示すように、読取工程Ｓ１１０では、加工装置２０の読取部２６によって、集合導線１の先端部１Ｆの断面形状を読み取る。読取部２６によって読み取る集合導線１の先端部１Ｆの断面形状は、集合導線１の先端部１Ｆの断面の一部であってもよく、集合導線１の先端部１Ｆにおける特定の素線１００の一部の断面形状であってもよい。本実施形態では、平角線の集合導線１の先端部１Ｆにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ１を、読取部２６によって読み取る。 Specifically, as shown in FIG. 6A, in the reading step S110, the cross-sectional shape of the tip portion 1F of the collective conductor 1 is read by the reading unit 26 of the processing apparatus 20. The cross-sectional shape of the tip portion 1F of the collective lead wire 1 read by the reading unit 26 may be a part of the cross section of the tip portion 1F of the collective lead wire 1, and is one of the specific strands 100 in the tip portion 1F of the collective lead wire 1. The cross-sectional shape of the portion may be used. In the present embodiment, the width W1 on the upper surface of the collective lead wire 1 of the strands 100 constituting the upper right corner portion of the tip portion 1F of the collective lead wire 1 of the flat wire is read by the reading unit 26.

読取工程Ｓ１１０の後、次に、図５に示すように、位相差算出工程Ｓ１２０に進む。位相差算出工程Ｓ１２０では、位相差算出手段によって、集合導線１の先端部１Ｆの位相と、集合導線１のピッチ開始位置ＰＳの位相との位相差を算出する。 After the reading step S110, the process proceeds to the phase difference calculation step S120 as shown in FIG. In the phase difference calculation step S120, the phase difference calculation means calculates the phase difference between the phase of the tip portion 1F of the collective lead wire 1 and the phase of the pitch start position PS of the collective lead wire 1.

具体的には、位相差算出手段は、集合導線１のピッチ開始位置ＰＳの断面形状を予め記憶している。予め記憶している集合導線１のピッチ開始位置ＰＳの断面形状は、集合導線１のピッチ開始位置ＰＳの断面の一部であってもよく、集合導線１のピッチ開始位置ＰＳにおける特定の素線１００の一部の断面形状であってもよい。本実施形態では、位相差算出手段は、平角線の集合導線１のピッチ開始位置ＰＳにおいて、右上角部を構成する素線１００の集合導線１の上面での幅Ｗを予め記憶している。 Specifically, the phase difference calculating means stores in advance the cross-sectional shape of the pitch start position PS of the collective conductor 1. The cross-sectional shape of the pitch start position PS of the collective conductor 1 stored in advance may be a part of the cross section of the pitch start position PS of the collective conductor 1, and is a specific strand in the pitch start position PS of the collective conductor 1. It may be a partial cross-sectional shape of 100. In the present embodiment, the phase difference calculating means stores in advance the width W on the upper surface of the collective conductor 1 of the strands 100 constituting the upper right corner portion at the pitch start position PS of the collective conductor 1 of the flat wire.

そして、位相差算出手段は、読取工程Ｓ１１０で読み取った幅Ｗ１と、予め記憶している幅Ｗとに基づいて、位相差Ｗ－Ｗ１を算出する。 Then, the phase difference calculating means calculates the phase difference WW1 based on the width W1 read in the reading step S110 and the width W stored in advance.

図５に示すように、位相差算出手段で算出した位相差Ｗ－Ｗ１が所定値±ΔＷの範囲内であった場合は、集合導線１の先端部１Ｆは、ピッチ開始位置ＰＳと略一致していると判断して、成型工程Ｓ２００に進む。位相差算出手段で算出した位相差Ｗ－Ｗ１が所定値±ΔＷの範囲外であった場合は、端部切断長さ算出工程Ｓ１３０に進む。 As shown in FIG. 5, when the phase difference WW1 calculated by the phase difference calculating means is within the range of the predetermined value ± ΔW, the tip portion 1F of the collective conductor 1 substantially coincides with the pitch start position PS. It is determined that this is the case, and the process proceeds to the molding step S200. If the phase difference WW1 calculated by the phase difference calculating means is out of the range of the predetermined value ± ΔW, the process proceeds to the end cutting length calculation step S130.

端部切断長さ算出工程Ｓ１３０では、端部切断長さ算出手段によって、位相差算出工程で算出した位相差Ｗ－Ｗ１に基づいて、集合導線１の先端部１Ｆから集合導線１のピッチ開始位置ＰＳまでの端部切断長さＬ１を算出する。 In the end cutting length calculation step S130, the pitch start position of the collective conductor 1 from the tip 1F of the collective conductor 1 based on the phase difference WW1 calculated in the phase difference calculation step by the end cut length calculation means. The end cutting length L1 up to PS is calculated.

具体的には、端部切断長さ算出手段は、集合導線１の所定ピッチＰ及び所定リード角θから得られる集合導線１の送り出し係数Ｋを予め記憶している。そして、端部切断長さ算出手段は、位相差算出工程で算出した位相差Ｗ－Ｗ１と、予め記憶している送り出し係数Ｋとから、端部切断長さＬ１を、Ｌ１＝（Ｗ－Ｗ１）×Ｋとして算出する。 Specifically, the end cutting length calculating means stores in advance the delivery coefficient K of the collective lead wire 1 obtained from the predetermined pitch P of the collective lead wire 1 and the predetermined lead angle θ. Then, the end cutting length calculating means sets the end cutting length L1 to L1 = (W-W1) from the phase difference W-W1 calculated in the phase difference calculating step and the feed coefficient K stored in advance. ) × K.

端部切断長さ算出工程Ｓ１３０の後、図５に示すように、端部切断工程Ｓ１４０に進む。端部切断工程Ｓ１４０は、集合導線１を端部切断長さＬ１だけ送り出す端部送出工程Ｓ１４１と、集合導線１を端部切断長さＬ１で切断する切断工程Ｓ１４２と、を含む。 After the end cutting length calculation step S130, the process proceeds to the end cutting step S140 as shown in FIG. The end cutting step S140 includes an end sending step S141 for sending the collective lead wire 1 by the end cutting length L1 and a cutting step S142 for cutting the collective lead wire 1 with the end cutting length L1.

具体的には、図６の（ｂ）に示すように、端部送出工程Ｓ１４１において、加工装置２０の送出部２１によって、集合導線１が端部切断長さＬ１だけ送り出される。そして、切断工程Ｓ１４２において、端部切断長さＬ１だけ送り出された集合導線１が加工装置２０の切断部２５によって、集合導線１は、先端部１Ｆから端部切断長さＬ１の位置で切断される。 Specifically, as shown in FIG. 6B, in the end sending step S141, the collecting conductor 1 is sent out by the sending portion 21 of the processing apparatus 20 by the end cutting length L1. Then, in the cutting step S142, the collective lead wire 1 sent out by the end cutting length L1 is cut by the cutting portion 25 of the processing apparatus 20 at the position of the end cutting length L1 from the tip portion 1F. To.

したがって、端部切断工程Ｓ１４０を実行後の集合導線１の先端部１Ｆは、ピッチ開始位置ＰＳと略一致することとなる。 Therefore, the tip 1F of the collective conductor 1 after executing the end cutting step S140 substantially coincides with the pitch start position PS.

そして、図５に示すように、端部切断工程Ｓ１４０の後、再び読取工程Ｓ１１０及び位相差算出工程Ｓ１２０に戻る。 Then, as shown in FIG. 5, after the end cutting step S140, the process returns to the reading step S110 and the phase difference calculation step S120 again.

このとき、集合導線１の先端部１Ｆは、ピッチ開始位置ＰＳと略一致しているので、位相差算出工程Ｓ１２０において、位相差算出手段で算出した位相差Ｗ－Ｗ１は所定値±ΔＷの範囲内となり、集合導線１の先端部１Ｆは、ピッチ開始位置ＰＳと略一致していると判断され、成型工程Ｓ２００に進む。 At this time, since the tip portion 1F of the collective conductor 1 substantially coincides with the pitch start position PS, the phase difference WW1 calculated by the phase difference calculation means in the phase difference calculation step S120 is in the range of a predetermined value ± ΔW. It is determined that the tip portion 1F of the collective conductor 1 substantially coincides with the pitch start position PS, and the process proceeds to the molding step S200.

成型工程Ｓ２００では、集合導線１を成型及び切断し、所定長さＬを有する集合導線片１０を得る。 In the molding step S200, the collective lead wire 1 is molded and cut to obtain a collective lead wire piece 10 having a predetermined length L.

図７に示すように、集合導線片１０は、頂部１１を備える山型部１２と、山型部１２の一対の端部１２ａ、１２ｂから略平行に延びる一対の脚部１３ａ、１３ｂと、を有する略Ｕ字状である。さらに、集合導線片１０の頂部１１は、一対の脚部１３ａ、１３ｂの延伸方向から見て、略Ｓ字状に湾曲している。 As shown in FIG. 7, the collective conductor piece 10 includes a mountain-shaped portion 12 having a top portion 11 and a pair of leg portions 13a and 13b extending substantially parallel to the pair of end portions 12a and 12b of the mountain-shaped portion 12. It has a substantially U-shape. Further, the top portion 11 of the collective conductor piece 10 is curved in a substantially S shape when viewed from the extending direction of the pair of leg portions 13a and 13b.

集合導線片１０は、頂部１１から山型部１２の一対の端部１２ａ、１２ｂまでの長さがそれぞれＬ１２となっており、一対の脚部１３ａ、１３ｂの長さがそれぞれＬ１３となっている。したがって、集合導線片１０の所定長さＬは、Ｌ＝２×Ｌ１２＋２×Ｌ１３となっている。 The length of the collective conductor piece 10 from the top portion 11 to the pair of end portions 12a and 12b of the chevron portion 12 is L12, respectively, and the lengths of the pair of leg portions 13a and 13b are L13, respectively. .. Therefore, the predetermined length L of the collective conductor piece 10 is L = 2 × L12 + 2 × L13.

成型工程Ｓ２００では、まず、加工装置２０の送出部２１によって、集合導線１の先端部１Ｆから長さＬ１３の位置が、加工装置２０のベンディング部２４の折り曲げ位置となるように、集合導線１が送り出される。そして、ベンディング部２４の第１ベンディング部２４１及び第２ベンディング部２４２によって、集合導線１は、先端部１Ｆから長さＬ１３の位置で折り曲げられ、脚部１３ａ及び山型部１２の端部１２ａが成型される。 In the molding step S200, first, the collective lead wire 1 is set by the delivery portion 21 of the processing apparatus 20 so that the position of the length L13 from the tip portion 1F of the collective lead wire 1 becomes the bending position of the bending portion 24 of the processing apparatus 20. Be sent out. Then, by the first bending portion 241 and the second bending portion 242 of the bending portion 24, the collective conductor 1 is bent at the position of the length L13 from the tip portion 1F, and the end portions 12a of the leg portion 13a and the chevron portion 12 are formed. It is molded.

次に、加工装置２０の送出部２１によって、山型部１２の端部１２ａから長さＬ１２の位置が、加工装置２０のベンディング部２４の折り曲げ位置となるように、集合導線１が送り出される。そして、図８の（ａ）に示すように、ベンディング部２４の第１ベンディング部２４１及び第２ベンディング部２４２によって、集合導線１は、山型部１２の端部１２ａから長さＬ１２の位置で折り曲げられ、脚部１３ａの延伸方向から見て略Ｓ字状に湾曲した頂部１１が成型される。 Next, the transmitting portion 21 of the processing apparatus 20 sends out the collective conductor 1 so that the position of the length L12 from the end portion 12a of the chevron portion 12 becomes the bending position of the bending portion 24 of the processing apparatus 20. Then, as shown in FIG. 8A, the first bending portion 241 and the second bending portion 242 of the bending portion 24 allow the collective conductor 1 to be positioned at a length L12 from the end portion 12a of the mountain-shaped portion 12. The top portion 11 which is bent and curved in a substantially S shape when viewed from the extending direction of the leg portion 13a is molded.

次に、加工装置２０の送出部２１によって、頂部１１から長さＬ１２の位置が、加工装置２０のベンディング部２４の折り曲げ位置となるように、集合導線１が送り出される。そして、ベンディング部２４の第１ベンディング部２４１及び第２ベンディング部２４２によって、集合導線１は、頂部１１から長さＬ１２の位置で折り曲げられ、山型部１２及び山型部の端部１２ｂが成型される。 Next, the transmitting portion 21 of the processing apparatus 20 sends out the collective conductor 1 so that the position of the length L12 from the top portion 11 becomes the bending position of the bending portion 24 of the processing apparatus 20. Then, by the first bending portion 241 and the second bending portion 242 of the bending portion 24, the collective conductor 1 is bent at the position of the length L12 from the top portion 11, and the chevron portion 12 and the end portion 12b of the chevron portion are molded. Will be done.

次に、図８の（ｂ）に示すように、加工装置２０の送出部２１によって、山型部１２の端部１２ｂから長さＬ１３の位置が、加工装置２０の切断部２５の切断位置となるように、集合導線１が送り出される。 Next, as shown in FIG. 8B, the position of the length L13 from the end portion 12b of the chevron portion 12 is set to the cutting position of the cutting portion 25 of the processing apparatus 20 by the sending portion 21 of the processing apparatus 20. As a result, the collective conductor 1 is sent out.

そして、切断部２５によって、集合導線１は、山型部１２の端部１２ｂから長さＬ１３の位置で切断され、脚部１３ｂが成型される。これにより、所定長さＬの集合導線片１０が製造され、成型工程Ｓ２００が完了する。 Then, the collective conductor 1 is cut from the end portion 12b of the chevron portion 12 at the position of the length L13 by the cutting portion 25, and the leg portion 13b is molded. As a result, the collective conductor piece 10 having a predetermined length L is manufactured, and the molding step S200 is completed.

成型工程Ｓ２００の後、図５に示すように、製造終了判定工程Ｓ３００に進む。製造終了判定工程Ｓ３００では、集合導線片１０の製造を終了すると判定した場合は、製造を終了し、集合導線片１０の製造を終了しないと判定した場合は、読取工程Ｓ１１０に戻り、再び所定長さＬの集合導線片１０が製造される。 After the molding step S200, the process proceeds to the production end determination step S300 as shown in FIG. In the production end determination step S300, if it is determined that the production of the collective lead piece 10 is terminated, the production is terminated, and if it is determined that the production of the collective lead piece 10 is not completed, the process returns to the reading step S110 and the predetermined length is again. The collective lead piece 10 of the L is manufactured.

製造終了判定工程Ｓ３００において、集合導線片１０の製造を終了するか否かの判定は、任意の判定方法を採用することができる。例えば、成型工程Ｓ２００によって成型された集合導線片１０の一対の脚部１３ａ、１３ｂの相対位置を、視覚または接触式計測等によって確認し、一対の脚部１３ａ、１３ｂの相対位置の誤差が許容範囲内であれば、集合導線片１０の製造を終了し、ＯＫ品搬送ラインへと搬送され、一対の脚部１３ａ、１３ｂの相対位置の誤差が許容範囲外であれば、加修品搬送ラインへと搬送されて、加修されるものとしてもよい。 In the production end determination step S300, any determination method can be adopted for determining whether or not to end the production of the collective conductor piece 10. For example, the relative positions of the pair of legs 13a and 13b of the collective lead piece 10 molded by the molding step S200 are confirmed by visual or contact measurement or the like, and an error in the relative positions of the pair of legs 13a and 13b is allowed. If it is within the range, the production of the collective lead wire piece 10 is completed and it is transported to the OK product transport line. If the error in the relative positions of the pair of legs 13a and 13b is out of the allowable range, the repaired product transport line It may be transported to and repaired.

成型工程Ｓ２００に進んだ集合導線１の先端部１Ｆは、ピッチ開始位置ＰＳと略同一であるので、成型工程Ｓ２００によって得られた複数の集合導線片１０は、いずれもピッチ開始位置ＰＳと略同位置から所定長さＬの集合導線片１０となる。よって、所定長さＬの複数の集合導線片１０は、特定位置における複数の素線１００の撚り合わせの配置及び形状、すなわち位相が略同一となる。したがって、複数の集合導線片１０について、頂部１１における断面形状は、全て略同一形状となっている。同様に、複数の集合導線片１０について、山型部１２の一対の端部１２ａ、１２ｂにおける断面形状は、全て略同一形状となっている。これにより、加工装置２０のベンディング部２４によって折り曲げられて頂部１１及び山型部１２の一対の端部１２ａ、１２ｂが成型される際に、集合導線片１０の折り曲げ部位に生じる応力分布が、いずれの集合導線片１０も略同一となるので、成型後の形状のばらつきを低減することができる。 Since the tip portion 1F of the collective lead wire 1 that has advanced to the molding step S200 is substantially the same as the pitch start position PS, the plurality of collective lead wire pieces 10 obtained by the molding step S200 are all substantially the same as the pitch start position PS. From the position, it becomes the collective lead wire piece 10 having a predetermined length L. Therefore, the plurality of collective conductor pieces 10 having a predetermined length L have substantially the same arrangement and shape, that is, the phases of the twists of the plurality of strands 100 at a specific position. Therefore, the cross-sectional shapes of the plurality of collective conductor pieces 10 at the top 11 are all substantially the same. Similarly, for the plurality of collective conductor pieces 10, the cross-sectional shapes of the pair of end portions 12a and 12b of the chevron portion 12 are all substantially the same shape. As a result, when the pair of ends 12a and 12b of the top portion 11 and the chevron portion 12 are bent by the bending portion 24 of the processing apparatus 20, the stress distribution generated at the bent portion of the collective conductor piece 10 will eventually be determined. Since the collective conductor pieces 10 of the above are also substantially the same, it is possible to reduce variations in the shape after molding.

また、位相差算出工程Ｓ１２０で算出した位相差Ｗ－Ｗ１が所定値±ΔＷの範囲内である場合は、端部切断長さ算出工程Ｓ１３０及び端部切断工程Ｓ１４０を行わずに成型工程Ｓ２００を行うので、所定長さＬの複数の集合導線片１０は、ピッチ開始位置ＰＳと略同位置から所定長さＬであることを保ちつつ、集合導線片１０の製造効率を向上できる。 When the phase difference W-W1 calculated in the phase difference calculation step S120 is within the range of the predetermined value ± ΔW, the molding step S200 is performed without performing the end cutting length calculation step S130 and the end cutting step S140. Therefore, it is possible to improve the manufacturing efficiency of the collective lead piece 10 while keeping the plurality of collective lead pieces 10 having the predetermined length L from substantially the same position as the pitch start position PS to the predetermined length L.

また、本実施形態では、集合導線１の少なくとも一部の断面形状、具体的には、少なくとも１つの素線１００の少なくとも一部の断面形状を読み取ることで、位相差を算出することができるので、読取工程Ｓ１１０及び位相差算出工程Ｓ１２０を簡素化することができる。 Further, in the present embodiment, the phase difference can be calculated by reading at least a part of the cross-sectional shape of the collective conductor 1, specifically, at least a part of the cross-sectional shape of at least one strand 100. , The reading step S110 and the phase difference calculation step S120 can be simplified.

さらに、本実施形態では、集合導線１は、断面略長方形状の平角線であり、読取工程Ｓ１１０で読み取った、先端部１Ｆにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ１と、予め記憶している、ピッチ開始位置ＰＳにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗとに基づいて、位相差Ｗ－Ｗ１を算出することができる。加えて、端部切断長さ算出工程Ｓ１３０において、集合導線１の所定ピッチＰ及び所定リード角θから得られる集合導線１の送り出し係数Ｋと、位相差Ｗ－Ｗ１とから、端部切断長さＬ１をＬ１＝（Ｗ－Ｗ１）×Ｋとして、端部切断長さＬ１を容易に算出することができるので、読取工程Ｓ１１０、位相差算出工程Ｓ１２０及び端部切断長さ算出工程Ｓ１３０をより簡素化することができる。 Further, in the present embodiment, the collective conductor 1 is a flat wire having a substantially rectangular cross section, and is the upper surface of the collective conductor 1 of the strands 100 constituting the upper right corner portion in the tip portion 1F read in the reading step S110. The phase difference W-W1 is calculated based on the width W1 of the above and the width W on the upper surface of the collective conductor 1 of the strands 100 constituting the upper right corner portion, which is stored in advance at the pitch start position PS. Can be done. In addition, in the end cutting length calculation step S130, the end cutting length is obtained from the delivery coefficient K of the collective lead wire 1 obtained from the predetermined pitch P and the predetermined lead angle θ of the collective lead wire 1 and the phase difference WW1. Since the end cutting length L1 can be easily calculated by setting L1 as L1 = (W-W1) × K, the reading step S110, the phase difference calculation step S120, and the end cutting length calculation step S130 are further simplified. Can be transformed into.

［第２実施形態］
続いて、本発明の第２実施形態の集合導線片１０の製造方法について、図９を参照して説明する。なお、以下の説明において、第１実施形態の集合導線片１０の製造方法と同一の構成要素については同一の符号を付して説明を省略又は簡略化する。 [Second Embodiment]
Subsequently, a method for manufacturing the collective conductor piece 10 according to the second embodiment of the present invention will be described with reference to FIG. In the following description, the same components as those of the method for manufacturing the collective conductor piece 10 of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.

第１実施形態の集合導線片１０の製造方法では、加工装置２０の読取部２６は、集合導線１の先端部１Ｆの断面形状を読み取るものとしたが、第２実施形態の集合導線片１０の製造方法では、加工装置２０の読取部２６は、集合導線１の先端部１Ｆの断面形状と、平角線である集合導線１の１つの外周面（本実施形態では、上面）に形成されている、複数の素線１００の隣接部ＰＬとを同時に読み取る。以下、第１実施形態の集合導線片１０の製造方法と、第２実施形態の集合導線片１０の製造方法との相違点について、詳細に説明する。 In the method for manufacturing the collective lead piece 10 of the first embodiment, the reading unit 26 of the processing apparatus 20 reads the cross-sectional shape of the tip portion 1F of the collective lead wire 1, but the collective lead wire piece 10 of the second embodiment. In the manufacturing method, the reading unit 26 of the processing apparatus 20 is formed on the cross-sectional shape of the tip portion 1F of the collective conductor 1 and one outer peripheral surface (upper surface in the present embodiment) of the collective conductor 1 which is a flat wire. , The adjacent portions PL of the plurality of strands 100 are read at the same time. Hereinafter, the difference between the method for manufacturing the collective conductor piece 10 of the first embodiment and the method for manufacturing the collective conductor piece 10 of the second embodiment will be described in detail.

図９の（ａ）及び（ｂ）に示すように、加工装置２０の読取部２６は、集合導線１の先端部１Ｆの断面と対向する位置の上方に配置され、集合導線１の先端部１Ｆの断面形状と、平角線である集合導線１の上面に形成されている、複数の素線１００の隣接部ＰＬの集合導線１の先端部１Ｆにおける形状と、を同時に読み取り可能になっている。 As shown in FIGS. 9A and 9B, the reading unit 26 of the processing apparatus 20 is arranged above the position facing the cross section of the tip portion 1F of the collective conductor 1 and is located above the tip portion 1F of the collective conductor 1. The cross-sectional shape of the above and the shape at the tip 1F of the collective conductor 1 of the adjacent portions PL of the plurality of strands 100 formed on the upper surface of the collective conductor 1 which is a flat wire can be read at the same time.

本実施形態では、加工装置２０の読取部２６によって、集合導線１の先端部１Ｆの断面形状と、平角線である集合導線１の上面に形成されている、複数の素線１００の隣接部ＰＬの集合導線１の先端部１Ｆにおける形状と、を同時に読み取る。 In the present embodiment, the reading unit 26 of the processing apparatus 20 forms the cross-sectional shape of the tip portion 1F of the collective lead wire 1 and the adjacent portion PL of the plurality of strands 100 formed on the upper surface of the collective lead wire 1 which is a flat wire. The shape of the collective lead wire 1 at the tip portion 1F of the above is read at the same time.

そして、読取部２６で読み取った、集合導線１の先端部１Ｆの断面形状と、平角線である集合導線１の上面に形成されている、複数の素線１００の隣接部ＰＬの集合導線１の先端部１Ｆにおける形状とから、平角線の集合導線１の先端部１Ｆにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ１を読み取る。 Then, the cross-sectional shape of the tip portion 1F of the collective conductor 1 read by the reading unit 26 and the collective conductor 1 of the adjacent portions PL of the plurality of strands 100 formed on the upper surface of the collective conductor 1 which is a flat wire. From the shape at the tip portion 1F, the width W1 on the upper surface of the collective lead wire 1 of the strands 100 constituting the upper right corner portion in the tip portion 1F of the collective lead wire 1 of the flat wire is read.

これにより、平角線の集合導線１の先端部１Ｆにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ１を、読取部２６で読み取った２つの面の形状から読み取るので、幅Ｗ１をより正確に読み取ることができる。 As a result, the width W1 on the upper surface of the collective conductor 1 of the strands 100 constituting the upper right corner portion of the tip portion 1F of the collective conductor 1 of the flat wire is read from the shapes of the two surfaces read by the reading unit 26. , The width W1 can be read more accurately.

［第３実施形態］
続いて、本発明の第２実施形態の集合導線片１０の製造方法について、図１０を参照して説明する。なお、以下の説明において、第１実施形態の集合導線片１０の製造方法と同一の構成要素については同一の符号を付して説明を省略又は簡略化する。 [Third Embodiment]
Subsequently, a method for manufacturing the collective conductor piece 10 according to the second embodiment of the present invention will be described with reference to FIG. In the following description, the same components as those of the method for manufacturing the collective conductor piece 10 of the first embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified.

第１実施形態の集合導線片１０の製造方法では、加工装置２０の読取部２６は、集合導線１の先端部１Ｆの断面と対向する位置に配置され、集合導線１の先端部１Ｆの断面形状を読み取るものとしたが、第２実施形態の集合導線片１０の製造方法では、加工装置２０の読取部２６は、平角線である集合導線１の１つの外周面（本実施形態では、上面）に形成されている、複数の素線１００の隣接部ＰＬを読み取る。以下、第１実施形態の集合導線片１０の製造方法と、第２実施形態の集合導線片１０の製造方法との相違点について、詳細に説明する。 In the method for manufacturing the collective lead piece 10 of the first embodiment, the reading unit 26 of the processing apparatus 20 is arranged at a position facing the cross section of the tip portion 1F of the collective lead wire 1, and the cross-sectional shape of the tip portion 1F of the collective lead wire 1 However, in the method of manufacturing the collective conductor piece 10 of the second embodiment, the reading unit 26 of the processing apparatus 20 is one outer peripheral surface of the collective conductor wire 1 which is a flat wire (upper surface in this embodiment). The adjacent portions PL of the plurality of strands 100 formed in the above are read. Hereinafter, the difference between the method for manufacturing the collective conductor piece 10 of the first embodiment and the method for manufacturing the collective conductor piece 10 of the second embodiment will be described in detail.

図１０の（ｂ）に示すように、加工装置２０の読取部２６は、送出部２１によって送り出される集合導線１の上方に配置されており、送出部２１によって送り出された集合導線１の上面の形状を読み取る。 As shown in FIG. 10B, the reading unit 26 of the processing apparatus 20 is arranged above the collective lead wire 1 sent out by the delivery unit 21, and is on the upper surface of the collective lead wire 1 sent out by the delivery unit 21. Read the shape.

図１０の（ａ）及び（ｂ）に示すように、まず、加工装置２０の送出部２１によって、集合導線１を長さＬ３だけ送出する。 As shown in FIGS. 10A and 10B, first, the transmitting unit 21 of the processing apparatus 20 transmits the collective conductor 1 by the length L3.

次に、加工装置２０の読取部２６によって、送出部２１によって送り出された集合導線１の上面の形状を読み取る。本実施形態では、平角線の集合導線１の先端部１Ｆから長さＬ３の位置、すなわち、加工装置２０の導線ガイド部２２によって保持されている位置において、集合導線１の上面に形成された複数の素線１００の隣接部ＰＬのうち、右上角部に隣接する隣接部ＰＬと、右上角部との長さとから、例えば、集合導線１の外周面を絶縁被覆する絶縁体１０１の厚さ等を考慮して、平角線の集合導線１の先端部１Ｆから長さＬ３の位置における、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ２を読み取る。 Next, the reading unit 26 of the processing apparatus 20 reads the shape of the upper surface of the collective conductor 1 sent out by the sending unit 21. In the present embodiment, a plurality of conductors formed on the upper surface of the collective conductor 1 at a position having a length L3 from the tip 1F of the collective conductor 1 of the flat wire, that is, a position held by the conductor guide portion 22 of the processing apparatus 20. From the lengths of the adjacent portion PL adjacent to the upper right corner portion and the upper right corner portion among the adjacent portions PL of the strand 100, for example, the thickness of the insulator 101 that insulates and covers the outer peripheral surface of the collective conductor 1. In consideration of the above, the width W2 on the upper surface of the collective conductor 1 of the strand 100 constituting the upper right corner portion at the position of the length L3 from the tip portion 1F of the collective conductor 1 of the flat wire is read.

読取工程Ｓ１１０の後、位相差算出工程Ｓ１２０に進む。位相差算出工程Ｓ１２０では、位相差算出手段によって、集合導線１の先端部１Ｆの位相と、集合導線１のピッチ開始位置ＰＳの位相との位相差を算出する。 After the reading step S110, the process proceeds to the phase difference calculation step S120. In the phase difference calculation step S120, the phase difference calculation means calculates the phase difference between the phase of the tip portion 1F of the collective lead wire 1 and the phase of the pitch start position PS of the collective lead wire 1.

具体的には、位相差算出手段は、読取工程Ｓ１１０で読み取った集合導線１の先端部１Ｆから長さＬ３の位置における、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ２と、送出部２１によって送り出された長さＬ３とから、集合導線１の先端部１Ｆにおける、右上角部を構成する素線１００の集合導線１の上面での幅Ｗ１を算出する。 Specifically, the phase difference calculating means is the width on the upper surface of the collective conductor 1 of the strands 100 constituting the upper right corner portion at the position of the length L3 from the tip portion 1F of the collective conductor 1 read in the reading step S110. From W2 and the length L3 sent out by the sending unit 21, the width W1 on the upper surface of the collective lead wire 1 of the strands 100 constituting the upper right corner portion in the tip portion 1F of the collective lead wire 1 is calculated.

そして、位相差算出手段は、算出した幅Ｗ１と、予め記憶している幅Ｗとに基づいて、位相差Ｗ－Ｗ１を算出する。 Then, the phase difference calculating means calculates the phase difference WW1 based on the calculated width W1 and the width W stored in advance.

これにより、複数の素線１００の隣接部ＰＬは、加工装置２０の読取部２６によって広範囲に認識することができるので、読取工程Ｓ１１０において、隣接部ＰＬを誤認識することが少なく、位相差算出工程Ｓ１２０において、より正確に位相差を算出することができる。 As a result, the adjacent portion PL of the plurality of strands 100 can be recognized in a wide range by the reading unit 26 of the processing apparatus 20, so that the adjacent portion PL is less likely to be erroneously recognized in the reading step S110, and the phase difference is calculated. In step S120, the phase difference can be calculated more accurately.

以上、本発明の実施形態を説明したが、本発明は上記実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。 Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be appropriately modified, improved, and the like.

例えば、第１実施形態及び第２実施形態では、集合導線１の右上角部を構成する素線１００の形状を読み取るものとしたが、右下角部、左上角部、左下角部を構成する素線１００の形状を読み取るものとしてもよいし、上面、下面、左面、右面の中央部を構成する素線１００の位置及び形状を読み取るものとしてもよい。 For example, in the first embodiment and the second embodiment, the shape of the wire 100 constituting the upper right corner portion of the collective conductor 1 is read, but the element constituting the lower right corner portion, the upper left corner portion, and the lower left corner portion. The shape of the wire 100 may be read, or the position and shape of the wire 100 constituting the central portion of the upper surface, the lower surface, the left surface, and the right surface may be read.

また、例えば、第１～第３実施形態では、成型工程Ｓ２００において、集合導線１は、加工装置２０のベンディング部２４によって折り曲げられて成型された後に切断されるものとしたが、集合導線１を所定長さＬで切断し、略直線状の集合導線片１０を得た後に成型されるものとしてもよい。 Further, for example, in the first to third embodiments, in the molding step S200, the collective lead wire 1 is bent and molded by the bending portion 24 of the processing apparatus 20, and then cut. It may be formed by cutting to a predetermined length L to obtain a substantially linear collective conductor piece 10.

また、例えば、第１～第３実施形態では、成型工程Ｓ２００において、集合導線１は、加工装置２０のベンディング部２４によって折り曲げられて成型されるものとしたが、成型手段は任意の手段を採用することができ、プレス機やマルチフォーミングマシンによってプレス成型されるものとしてもよい。その際、集合導線１を所定長さＬで切断し、略直線状の集合導線片１０を得た後に成型されるものとしてもよい。 Further, for example, in the first to third embodiments, in the molding step S200, the collective conductor 1 is bent and molded by the bending portion 24 of the processing apparatus 20, but any means is adopted as the molding means. It may be press-molded by a press machine or a multi-forming machine. At that time, the collective lead wire 1 may be cut to a predetermined length L to obtain a substantially linear collective lead wire piece 10 and then molded.

また、例えば、第２実施形態及び第３実施形態では、集合導線１の上面の隣接部ＰＬを読み取るものとしたが、左面、右面または下面の隣接部ＰＬを読み取るものとしてもよい。 Further, for example, in the second embodiment and the third embodiment, the adjacent portion PL on the upper surface of the collective conductor 1 is read, but the adjacent portion PL on the left surface, the right surface, or the lower surface may be read.

また、例えば、第１～第３実施形態では、一端部がピッチ開始位置ＰＳである所定長さＬの集合導線片１０のみが製造されるものとしたが、異なる長さ及び／または位相を有する複数種類の集合導線片１０ａ、１０ｂ、１０ｃが製造されるものとしてもよい。例えば、異なるピッチ開始位置ＰＳａ、ＰＳｂ、ＰＳｃを有する複数種類の集合導線片１０ａ、１０ｂ、１０ｃが製造されるものであって、ピッチ開始位置ＰＳａ、ＰＳｂ、ＰＳｃのうち、読取工程Ｓ１１０で読み取った幅Ｗ１からの位相差が最も小さいピッチ開始位置がピッチ開始位置ＰＳｂの場合、ピッチ開始位置ＰＳｂまでの端部切断長さで切断して、当該ピッチ開始位置を一端部とする集合導線片１０ｂを成型するものとしてもよい。このようにすると、端部切断工程Ｓ１４０で切断する集合導線１の長さを短くすることができ、無駄になる集合導線１を少なくすることができるので、集合導線１の歩留まりを向上することができる。 Further, for example, in the first to third embodiments, only the collective conductor piece 10 having a predetermined length L whose one end is the pitch start position PS is manufactured, but it has a different length and / or phase.
