Abstract

A measured/cut wire (65) is installed, in roughly the shape of a U, on a wire retention rod (62). When doing so, each terminal (66, 67) of the measured/cut wire (65) protrudes and faces one direction. As a consequence, the area to be wiped by a terminal wiping part (70) is limited to each terminal (66, 67) only. The terminal wiping part (70) is provided with a pair of wiping parts (74) which is the main body of the terminal wiping part, and a first movement mechanism (75) and a second movement mechanism (76) for moving the pair of wiping parts (74). The pair of wiping parts (74) moves so as to scrub the entire outer surface after coming into contact with the terminals (66, 67) by sandwiching same from the top and bottom. The terminal wiping unit (70) does not only have the function to wipe dirt off of the terminals (66, 67) but also the function to straighten and extend the terminals (66, 67).

Description

ワイヤハーネス生産システム及びワイヤハーネス生産方法Wire harness production system and wire harness production method
　本発明は、電線被覆部を着色材で着色をするための着色ユニットをシステム構成に含むワイヤハーネス生産システム及びワイヤハーネス生産方法に関する。 The present invention relates to a wire harness production system and a wire harness production method including a coloring unit for coloring a wire covering portion with a coloring material in the system configuration.
　電力や信号を伝えるための電線は、導電性を有する金属製の導体と、絶縁性を有し導体を被覆する樹脂製の絶縁体とを備えて構成される。このような構成の電線は、導体が芯線や電線導体部などと呼ばれることもあり、また、絶縁体が被覆や電線被覆部などと呼ばれることもある。電線は、上記のように電力や信号を伝えるために用いられることから、その用途に応じて導体の材質や太さや構成、絶縁体の材質や厚みなどが異なる。例えば、導体の場合、銅や銅合金、或いはアルミニウムやアルミニウム合金などが採用される。そして、このような材質で素線をつくり、素線を単に束ねたものや撚り合わせたものにて導体が形成される。或いは、素線ではなく単芯構造のもので導体が形成されることもある。電線の太さは、例えば導体断面積で表され、小さいものから大きなものまで様々ある。尚、電線の太さは、上記素線の本数によっても異なってくる。一方、絶縁体に関しては、耐熱性や耐候性、耐薬品性、耐摩耗性、難燃性などを考慮して樹脂材料が選定される。また、絶縁性を確保するために厚みも適宜設定される。以上から電線は様々な種別のものがあることが分かる。 An electric wire for transmitting electric power and signals includes a conductive metal conductor and an insulating resin insulator that covers the conductor. In the electric wire having such a configuration, the conductor may be referred to as a core wire or an electric wire conductor portion, and the insulator may be referred to as a covering or an electric wire covering portion. Since the electric wire is used to transmit electric power and signals as described above, the material, thickness, and configuration of the conductor and the material, thickness, etc. of the insulator differ depending on the application. For example, in the case of a conductor, copper, a copper alloy, aluminum, an aluminum alloy, or the like is employed. Then, a strand is made of such a material, and a conductor is formed by simply bundling or twisting the strands. Alternatively, the conductor may be formed of a single-core structure instead of a strand. The thickness of the electric wire is expressed by, for example, a conductor cross-sectional area, and varies from a small one to a large one. In addition, the thickness of an electric wire changes with the number of the said strands. On the other hand, for the insulator, a resin material is selected in consideration of heat resistance, weather resistance, chemical resistance, wear resistance, flame resistance, and the like. In addition, the thickness is appropriately set in order to ensure insulation. From the above, it can be seen that there are various types of electric wires.
　電線は一本のみで使用されることもあるが、自動車（移動体）の場合、電線は多数使用される。多数の電線は、ワイヤハーネスを構成するものとして使用される。ワイヤハーネスに関し説明をすると、自動車にはクルマの基本性能、すなわち走る・曲がる・止まるという性能や、安全性、そして利便性や快適性を可能にする様々な電子機器が搭載される。これら様々な電子機器は、バッテリーからの電力と制御信号によって動作することになり、この電力と信号の伝送を担うのがワイヤハーネスとなる。ワイヤハーネスは、機器の種類、流す電流の値、配索位置などにより、様々な種別（長さ、太さ、絶縁体材料）の電線が必要になる。 There are cases where only one electric wire is used, but in the case of an automobile (moving body), many electric wires are used. Many electric wires are used as what comprises a wire harness. To explain wire harnesses, automobiles are equipped with various electronic devices that enable the basic performance of a car, that is, the ability to run, bend and stop, as well as safety, convenience, and comfort. These various electronic devices are operated by electric power from the battery and a control signal, and a wire harness is responsible for transmission of the electric power and the signal. The wire harness requires various types of wires (length, thickness, insulator material) depending on the type of device, the value of the current to be passed, the position of wiring, and the like.
　様々な種別の電線を多数備えたワイヤハーネスは、例えば電線自体の外観が全て同じであれば、その製造がきわめて困難になってしまうことになる。また、機器同士を接続するにあたり、誤った接続が生じてしまうことにもなる。さらには、メンテナンスに支障を来してしまうことにもなる。そこで、様々な種別の電線を識別するために、電線被覆部に着色やマーキングを施すことが一般的である。特許文献１には、ワイヤハーネスを製造する方法の提案の中で、電線被覆部に着色やマーキングをする方法について示されている。 If a wire harness having a large number of various types of electric wires has the same external appearance, for example, it will be very difficult to manufacture. In addition, when connecting the devices, an erroneous connection may occur. In addition, maintenance may be hindered. Therefore, in order to identify various types of electric wires, it is common to color or mark the electric wire covering portion. Patent Document 1 discloses a method for coloring or marking an electric wire covering portion in a proposal of a method for manufacturing a wire harness.
　特許文献１の開示技術を簡単に説明すると、ワイヤハーネスの製造方法において、電線を製造する工程、電線を切断する工程、電線被覆部を除去する工程、端子金具を圧着接続する工程、ケース嵌めを行う工程があり、それぞれの工程の直前には、これらの工程に必要な情報を得るための着色やマーキングを施す。 Briefly explaining the disclosed technique of Patent Document 1, in the method of manufacturing a wire harness, a step of manufacturing an electric wire, a step of cutting the electric wire, a step of removing the electric wire covering portion, a step of crimping and connecting terminal fittings, and case fitting There are processes to be performed, and coloring and marking for obtaining information necessary for these processes is performed immediately before each process.

　ワイヤハーネスを構成する電線は、電線製造工場からワイヤハーネス組立工場に運ばれ、そして、ワイヤハーネス組立工場では、例えば一定期間在庫保存されるようなことがある。また、着色を行う工程の前には、電線を切断し、運搬する等、種々の工程がある。そのため、着色前の電線被覆部には、埃などの不純物が付着することが考えられる。仮にそのような不純物が付着していた場合は、着色材である染料の電線被覆部内への染み込み、或いは、着色材である顔料の電線被覆部への接着がうまくいかずに「にじみ」が生じることがある。 The wires constituting the wire harness are transported from the wire manufacturing factory to the wire harness assembly factory, and the wire harness assembly factory may be stocked for a certain period of time, for example. Moreover, before the process of coloring, there are various processes such as cutting and transporting the electric wires. For this reason, it is considered that impurities such as dust adhere to the wire covering portion before coloring. If such impurities are attached, the colorant dye penetrates into the wire coating part or the colorant pigment adheres to the wire coating part and "bleeding" occurs. Sometimes.
　本発明は、上記した事情に鑑みてなされたもので、着色材の「にじみ」を防止することが可能なワイヤハーネス生産システム及びワイヤハーネス生産方法を提供することを課題とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wire harness production system and a wire harness production method capable of preventing “bleeding” of a coloring material.
　本発明の第１の態様に係るワイヤハーネス生産システムは、電線の電線被覆部を着色材で着色をするための着色ユニットと、着色ユニットよりも前工程側のシステム構成として、電線の長さを測定するための検尺部を備える。着色ユニットは、該着色ユニットを通過する電線の電線被覆部を着色するための着色ユニット本体部と、着色ユニット本体部よりも前工程となり且つ電線被覆部の拭き取りを行うための拭き取り部とを備える。 The wire harness production system according to the first aspect of the present invention includes a coloring unit for coloring an electric wire covering portion of an electric wire with a coloring material, and a system configuration on the side of the previous process with respect to the coloring unit. A measuring part for measuring is provided. The coloring unit includes a coloring unit main body for coloring the electric wire covering portion of the electric wire passing through the coloring unit, and a wiping portion that is a pre-process before the coloring unit main body and wipes the electric wire covering portion. .
　このような構成により、電線の電線被覆部を着色材で着色する前に、電線被覆部に対して拭き取りを行うことから、着色材の「にじみ」を防止することができる。 With such a configuration, since the electric wire covering portion is wiped before the electric wire covering portion of the electric wire is colored with the coloring material, the “bleeding” of the coloring material can be prevented.
　拭き取り部は、電線被覆部における着色をしたい一定範囲に接触して拭き取りを行ってもよく、着色ユニット本体部は、一定範囲に着色部を形成してもよい。 The wiping portion may be wiped in contact with a certain range to be colored in the wire covering portion, and the coloring unit main body portion may form a colored portion in the certain range.
　このような構成により、着色をしたい一定範囲を拭き取り部にて拭き取ることから、無駄に拭き取る部分を抑えて拭き取り部の耐久性を高めることができる。また、一定範囲の拭き取りをすればよいので、システムの制御を単純化することもできる。 With such a configuration, since a certain range to be colored is wiped off by the wiping portion, it is possible to increase the durability of the wiping portion by suppressing a portion to be wiped uselessly. In addition, since it is sufficient to wipe a certain range, the control of the system can be simplified.
　ワイヤハーネス生産システムは、検尺部の測定に基づいて電線を指示した長さで切断し検尺切断電線を得るための電線切断部と、複数の電線保持部を有する電線保持竿と、検尺切断電線を電線保持竿に略Ｕ字状にセットするとともに検尺切断電線の各端末を着色ユニットの配置側に突出させて電線保持部に各々保持させるための電線Ｕ字状セット部とを更に備えてもよい。拭き取り部は、検尺切断電線の各端末の拭き取りを行う端末拭き取り部としての機能を有してもよい。 The wire harness production system includes an electric wire cutting part for obtaining an electric cut wire by cutting an electric wire based on the measurement of the measuring part, an electric wire holding rod having a plurality of electric wire holding parts, An electric wire U-shaped set portion for setting the cut electric wire to the electric wire holding rod in a substantially U shape and causing each end of the scale cut electric wire to protrude to the arrangement side of the coloring unit and hold the electric wire holding portion respectively. You may prepare. The wiping unit may have a function as a terminal wiping unit for wiping each terminal of the scale-cut electric wire.
　このような構成により、検尺切断電線を電線保持竿に略Ｕ字状にセットすることで、この検尺切断電線の各端末を突出させて一方向に向くようにすることができる。これにより、拭き取り対象を各端末のみの一定範囲にすることができる。従って、無駄に拭き取る部分を抑えて拭き取り部の耐久性を高めることができる。また、一定範囲の拭き取りをすればよいので、システムの制御を単純化することもできる。 With such a configuration, by setting the measured cut electric wire to the electric wire holding rod in a substantially U shape, each end of the measured cut electric wire can be projected and directed in one direction. Thereby, the object to wipe can be made into the fixed range only of each terminal. Therefore, it is possible to increase the durability of the wiping portion by suppressing the portion to be wiped uselessly. In addition, since it is sufficient to wipe a certain range, the control of the system can be simplified.
　拭き取り部は、各端末に接触可能な端末拭き取り部本体と、該端末拭き取り部本体を各端末の突出方向に沿って移動させるための移動機構とを備えてもよい。 The wiping unit may include a terminal wiping unit main body that can contact each terminal, and a moving mechanism for moving the terminal wiping unit main body along the protruding direction of each terminal.
　このような構成により、突出して一方向に向く検尺切断電線の各端末を、端末の突出方向に沿って拭き取るようにすることができ、この拭き取りに伴って各端末を真っ直ぐにのばすこともできる。従って、正確な位置に着色をすることができるようになるとともに、着色ユニットよりも後工程においては、例えば端子金具を正確な位置に取り付けすることもできる。 With such a configuration, it is possible to wipe each end of the scale-cut electric wire protruding and facing in one direction along the protruding direction of the terminal, and each terminal can be straightened along with this wiping. . Accordingly, it is possible to color the correct position, and it is also possible to attach, for example, the terminal fitting to the correct position in a later process than the coloring unit.
　ワイヤハーネス生産システムは、着色ユニットよりも後工程側のシステム構成として、検尺切断電線の各端末を各々皮むきして電線導体部を露出させるための端末皮むき部と、該端末皮むき部により露出した電線導体部に所望の端子金具を取り付けるための端子取付部とを備えてもよい。端末皮むき部と端子取付部の配置としては、各端末の突出方向側の配置としてもよい。 The wire harness production system has a system configuration on the side of the subsequent process with respect to the coloring unit, a terminal stripping part for stripping each terminal of the scale cut electric wire to expose the wire conductor part, and the terminal stripping part And a terminal attaching part for attaching a desired terminal fitting to the exposed wire conductor part. As arrangement | positioning of a terminal peeling part and a terminal attachment part, it is good also as arrangement | positioning by the side of the protrusion direction of each terminal.
　このような構成により、突出した端末の方向に全ての装置が設けられ、このような配置で端子金具の取り付けまでの一連の工程を一つの流れで行えるようにすることができる。よって、その一連の工程の中で一つの着色ユニットで着色をし、例えばサブハーネスを生産することができる。 With such a configuration, all devices are provided in the direction of the protruding terminal, and with this arrangement, a series of steps up to the attachment of the terminal fitting can be performed in one flow. Therefore, it can color with one coloring unit in the series of processes, for example, can produce a subharness.
　本発明の第２の態様に係るワイヤハーネス生産方法は、電線被覆部に対し着色材で着色をする着色工程と、着色工程よりも前工程として、電線の長さを測定する検尺工程を含む。着色工程は、着色ユニットを通過する電線の電線被覆部を着色する前に電線被覆部の拭き取りを行うことを含む。 The wire harness production method according to the second aspect of the present invention includes a coloring step of coloring the wire covering portion with a coloring material, and a measuring step of measuring the length of the wire as a pre-process before the coloring step. . The coloring step includes wiping the wire covering portion before coloring the wire covering portion of the electric wire passing through the coloring unit.
　このような構成により、着色材の「にじみ」を防止することができる。 Such a configuration can prevent “bleeding” of the coloring material.
　本発明の各態様によれば、着色ユニットを通過する電線に対し、この電線被覆部の拭き取りを行ってから着色をすることから、別な言い方をすれば、電線被覆部を着色材で着色する前に、電線被覆部に対して拭き取りを行うことから、着色材の「にじみ」を防止することができるという効果を奏する。 According to each aspect of the present invention, the electric wire passing through the coloring unit is colored after wiping off the electric wire covering portion. In other words, the electric wire covering portion is colored with a coloring material. Since the electric wire covering portion is wiped before, the “bleeding” of the coloring material can be prevented.

　以下、実施例に係るワイヤハーネス生産システムの基本的な構成について、図１－８を参照して説明する。 Hereinafter, the basic configuration of the wire harness production system according to the embodiment will be described with reference to FIG. 1-8.
　図１に示すように、基本的な実施例に係るワイヤハーネス生産システム１は、ワイヤハーネスを構成するサブハーネスなどの中間生産品を生産するためのシステムである。図１に示すワイヤハーネス生産システム１は、図８に示すサブハーネス２（中間生産品）を生産するまでの構成を示す。 As shown in FIG. 1, a wire harness production system 1 according to a basic embodiment is a system for producing intermediate products such as sub-harnesses constituting a wire harness. The wire harness production system 1 shown in FIG. 1 shows a configuration until the sub-harness 2 (intermediate product) shown in FIG. 8 is produced.
　ワイヤハーネス生産システム１は、第一システム構成群３と、第二システム構成群４と、第三システム構成群５と、第一ストック部６と、第二ストック部７と、第三ストック部８とを備える。 The wire harness production system 1 includes a first system configuration group 3, a second system configuration group 4, a third system configuration group 5, a first stock unit 6, a second stock unit 7, and a third stock unit 8. With.
　第一システム構成群３では、図８に示すサブハーネス２を構成するものとして、複数の端子付き後識別電線９（後識別電線群１０）が得られる。端子付き後識別電線９には、サブハーネス２の生産に有効な後識別の部分として、着色部１１が形成される。この着色部１１は、着色ユニット１２を用い、着色材で電線被覆部１３を着色することにより形成される。第一システム構成群３は、着色ユニット１２の他に、電線端末集合部１４と、選択電線引出部１５と、検尺部１６と、電線切断部１７と、端末皮むき部１８と、端子取付部１９と、電線保持竿２０と、電線Ｕ字状セット部２１と、電線保持竿移動部２２とを備える。着色ユニット１２は、電線切断部１７と端末皮むき部１８との間に配置される。 In the first system configuration group 3, a plurality of rear identification electric wires 9 with terminals (rear identification electric wire group 10) are obtained as components constituting the sub-harness 2 shown in FIG. A colored portion 11 is formed in the post-identification electric wire 9 with a terminal as a post-identification portion effective for the production of the sub-harness 2. The colored portion 11 is formed by using the coloring unit 12 and coloring the wire covering portion 13 with a coloring material. In addition to the coloring unit 12, the first system configuration group 3 includes an electric wire terminal assembly portion 14, a selected electric wire drawing portion 15, a measuring portion 16, an electric wire cutting portion 17, an end skinning portion 18, and terminal attachment. A portion 19, an electric wire holding rod 20, an electric wire U-shaped set portion 21, and an electric wire holding rod moving portion 22 are provided. The coloring unit 12 is disposed between the wire cutting part 17 and the terminal peeling part 18.
　電線端末集合部１４では、リールに巻かれた複数種の電線２３の各電線端末２４が集められ、この各電線端末２４が各々保持される。選択電線引出部１５では、一つのサブハーネス２を構成する電線種別に基づき電線２３が選択され、選択電線２５として電線端末集合部１４から引き出される。引き出された選択電線２５は、この後に電線切断部１７で指示された長さに切断されて検尺切断電線２６となる。検尺切断電線２６は、電線Ｕ字状セット部２１により電線保持竿２０に略Ｕ字状にセットされる。 In the electric wire terminal gathering part 14, the electric wire terminals 24 of the plural types of electric wires 23 wound around the reel are collected, and the electric wire terminals 24 are respectively held. In the selected electric wire lead-out portion 15, the electric wire 23 is selected based on the type of electric wire constituting one sub-harness 2, and is drawn out from the electric wire terminal assembly portion 14 as the selected electric wire 25. The drawn selected electric wire 25 is then cut to a length designated by the electric wire cutting unit 17 to become a scale cut electric wire 26. The scale cut electric wire 26 is set in a substantially U-shape on the electric wire holding rod 20 by the electric wire U-shaped set portion 21.
　検尺切断電線２６の端末は、電線被覆部１３の外表面の一定範囲が拭き取られるとともに、拭き取られた部分に対し着色ユニット１２の本体部分により着色がなされる。着色部１１は、着色ユニット１２の意匠確認部分で検査される。 The end of the scale-cutting electric wire 26 is wiped off a certain range of the outer surface of the electric wire covering portion 13 and is colored by the main body portion of the coloring unit 12 with respect to the wiped portion. The colored portion 11 is inspected at the design confirmation portion of the colored unit 12.
　端子取付部１９では、端子金具２７が取り付けられ、これにより端子付き後識別電線９が得られる。端子付き後識別電線９は、電線保持竿２０に複数保持された状態で後識別電線群１０となる。 In the terminal attachment part 19, the terminal metal fitting 27 is attached, and the rear identification electric wire 9 with a terminal is obtained by this. The rear identification electric wires 9 with terminals become the rear identification electric wire group 10 in a state where a plurality of electric wires 9 are held by the electric wire holding rod 20.
　第二システム構成群４では、電線保持竿２０において複数保持された端子付き後識別電線９（後識別電線群１０）から図７に示すサブハーネス２が部分的に生産される。第二システム構成群４では、ハウジング２８のキャビティに対し端子金具２７が自動挿入（自動収容）される。 In the second system configuration group 4, the sub-harness 2 shown in FIG. 7 is partially produced from the rear identification electric wires 9 with terminals (rear identification electric wire group 10) held in the electric wire holding rod 20. In the second system configuration group 4, the terminal fitting 27 is automatically inserted (automatically accommodated) into the cavity of the housing 28.
　第三システム構成群５では、サブハーネス２が図８に示す如く完成するように生産される。第三システム構成群５では、自動機化が困難な工程が行われる。具体的には、第三システム構成群５では、第二システム構成群４において自動挿入することができなかった端子金具２７（例えば、他と逆向きに挿入する場合など）を手動で挿入する工程が行われる。また、第三システム構成群５では、端子付き後識別電線９をツイストする工程や、電線同士をジョイントする工程等が行われる。この他、第三システム構成群５では、グロメットなどのような予め組み付けておいた方がよい外装部品を手動で組み付ける工程も行われる。 In the third system configuration group 5, the sub harness 2 is produced so as to be completed as shown in FIG. In the third system configuration group 5, a process that is difficult to be automated is performed. Specifically, in the third system configuration group 5, a step of manually inserting the terminal fitting 27 (for example, when inserted in the opposite direction) that could not be automatically inserted in the second system configuration group 4. Is done. Moreover, in the 3rd system structure group 5, the process of twisting the back identification electric wire 9 with a terminal, the process of jointing electric wires, etc. are performed. In addition, in the third system configuration group 5, a step of manually assembling exterior parts such as grommets that should be assembled in advance is also performed.
　第一システム構成群３により得られた後識別電線群１０は、第一ストック部６にストックされる。第二システム構成群４により得られたサブハーネス２は、第二ストック部７にストックされる。第三システム構成群５により得られたサブハーネス２は、第三ストック部８にストックされる。尚、図示しないが、第三ストック部８にストックされた後のサブハーネス２は、布線板にセットされてワイヤハーネスとして組み立てられる。 The post-identification electric wire group 10 obtained by the first system configuration group 3 is stocked in the first stock unit 6. The sub-harness 2 obtained by the second system configuration group 4 is stocked in the second stock unit 7. The sub harness 2 obtained by the third system configuration group 5 is stocked in the third stock unit 8. Although not shown, the sub-harness 2 after being stocked in the third stock portion 8 is set on a wiring board and assembled as a wire harness.
　ワイヤハーネス生産システム１では、検尺切断電線２６を電線保持竿２０に略Ｕ字状にセットすることで、この検尺切断電線２６の各端末を一方向に向くようにすることができる。これにより、拭き取り対象を各端末のみの一定範囲にすることができる。着色部１１は、例えば汚れが拭き取られた部分に形成されることから、「にじみ」が生じることはない。 In the wire harness production system 1, by setting the measuring wire 26 to the wire holding rod 20 in a substantially U shape, each end of the measuring wire 26 can be oriented in one direction. Thereby, the object to wipe can be made into the fixed range only of each terminal. Since the colored portion 11 is formed, for example, in a portion where dirt has been wiped off, “smudge” does not occur.
　着色ユニット１２に関し、これを「着色ユニット及び／又はマーキングユニット」と読み替えてもよい。マーキングユニットは、着色材でマーキングするためのユニットである。 The color unit 12 may be read as “coloring unit and / or marking unit”. The marking unit is a unit for marking with a coloring material.
　サブハーネス２に関し、「サブハーネス」とは、端子金具２７（圧着端子など）が全てコネクタハウジングに挿入された状態や、ジョイントされた状態にあるものを指す。別な言い方をすれば、「サブハーネス」とは、全ての端子金具２７が露出してない状態のものを指す。 Regarding the sub-harness 2, the “sub-harness” refers to a state in which all the terminal fittings 27 (crimp terminals, etc.) are inserted into the connector housing or in a jointed state. In other words, the “sub-harness” refers to a state in which all the terminal fittings 27 are not exposed.
　着色部１１に関し、着色状態は、図示のように周方向に線状（帯状）にする他、ドット（・・）やマーク（○、△、Ａ、Ｂ等）等にしてもよい。 As for the colored portion 11, the colored state may be linear (strip-shaped) in the circumferential direction as shown, or may be dots (..), marks (◯, Δ, A, B, etc.).
　尚、第三システム構成群５を備えず、端子金具２７を全て自動挿入するような構成にしてもよい。また、逆に、第二システム構成群４を備えず、端子金具２７を全て手動挿入するような構成にしてもよい。さらに、第二システム構成群４と第三システム構成群５の配置の順を、図示の逆にしてもよい。或いは、第二システム構成群４と第三システム構成群５のどちらか一方又は両方を、二つ並列に並べてもよい。 Note that the third system configuration group 5 may not be provided, and the terminal fittings 27 may all be automatically inserted. Conversely, the second system configuration group 4 may not be provided, and all the terminal fittings 27 may be manually inserted. Furthermore, the order of arrangement of the second system configuration group 4 and the third system configuration group 5 may be reversed. Alternatively, either one or both of the second system configuration group 4 and the third system configuration group 5 may be arranged in parallel.
　以下、実施例に係るワイヤハーネス生産システムの詳細な構成について、図９－１９を参照しながら説明する。 Hereinafter, the detailed configuration of the wire harness production system according to the embodiment will be described with reference to FIGS.
　図９に示すように、詳細な実施例に係るワイヤハーネス生産システム３１は、サブハーネス生産ライン３２と、ワイヤハーネス組み立てライン３３とを備える。尚、サブハーネス生産ライン３２を前工程ライン３４、ワイヤハーネス組み立てライン３３を後工程ライン３５と呼んでもよい。 As shown in FIG. 9, the wire harness production system 31 according to the detailed embodiment includes a sub-harness production line 32 and a wire harness assembly line 33. The sub-harness production line 32 may be referred to as a pre-process line 34, and the wire harness assembly line 33 may be referred to as a post-process line 35.
　サブハーネス生産ライン３２は、二つのラインで構成される。サブハーネス生産ライン３２は、第一システム構成群３６と、第二システム構成群３７と、第一ストック部３８（３８ａ、３８ｂ）と、第二ストック部３９（３９ａ、３９ｂ）とを含む自動機対応が可能なライン、及び、第三システム構成群４１と、第三ストック部４２（４２ａ、４２ｂ）とを含む手動で対応するライン（作業員による組み立てが行われるライン）を備える。第一システム構成群３６には、着色ユニット４０が設けられる。 The sub-harness production line 32 is composed of two lines. The subharness production line 32 includes an automatic machine including a first system configuration group 36, a second system configuration group 37, a first stock section 38 (38a, 38b), and a second stock section 39 (39a, 39b). A line capable of handling, and a manually corresponding line including the third system configuration group 41 and the third stock portion 42 (42a, 42b) (a line where assembly by a worker is performed) are provided. In the first system configuration group 36, a coloring unit 40 is provided.
　尚、サブハーネス生産ライン３２は、二つのラインであるものとして説明するが、特にライン数を限定するものでなく、例えば一つのラインであってもよい。 Although the sub-harness production line 32 is described as being two lines, the number of lines is not particularly limited, and may be one line, for example.
　自動機対応が可能なラインである第一システム構成群３６及び第二システム構成群３７は、コンピュータ(不図示)により制御され、制御機構(不図示)により作動する。コンピュータによる制御部は、システム構成毎に制御することができるように、或いは全体を一括して制御することができるように構成される。制御部は、ＣＰＵやＲＡＭ、ＲＯＭ等を有する。サブハーネスの種類に応じたプログラミングにより、生産手順や生産スピード等の変更が可能であり、例えば供給部品が数多くあっても、確実に選択等をすることができる。この他、制御部による制御によって、生産途中での良否判定等が可能になる。 The first system configuration group 36 and the second system configuration group 37, which are lines capable of handling automatic machines, are controlled by a computer (not shown) and operated by a control mechanism (not shown). The computer control unit is configured to be able to control every system configuration, or to be able to control the entire system collectively. The control unit includes a CPU, a RAM, a ROM, and the like. Programming according to the type of the sub-harness can change the production procedure, production speed, and the like. For example, even if there are many parts to be supplied, the selection can be made reliably. In addition, it is possible to determine pass / fail during the production by the control of the control unit.
　ワイヤハーネス組み立てライン３３は、サブハーネス生産ライン３２よりも下流側に設置される組み立て専用のラインである。ワイヤハーネス組み立てライン３３では、図８のサブハーネス２を一又は二以上を布線板上で組み立てる。この時に、テープ巻き、外装部品の取り付け等をすることによって、図１０に示すようなワイヤハーネス４３が組み立てられる。図１０のワイヤハーネス４３の構成や外観形状は一例である。ここでは、プロテクタやグロメット等の外装部品の図示を省略する。 The wire harness assembly line 33 is a dedicated assembly line installed on the downstream side of the sub-harness production line 32. In the wire harness assembly line 33, one or two or more sub-harnesses 2 in FIG. 8 are assembled on the wiring board. At this time, the wire harness 43 as shown in FIG. 10 is assembled by tape winding, attachment of exterior parts, and the like. The configuration and external shape of the wire harness 43 in FIG. 10 are examples. Here, illustration of exterior parts such as a protector and a grommet is omitted.
　図１０において、ワイヤハーネス４３は、電線４４の束であって、自動車（移動体）の所定位置に配索されて電力や信号を伝える。自動車において必要な電線本数は、所謂普及車から高級車までを含めて挙げると、数百本から場合によっては千本を超えることもある。このようなワイヤハーネス４３は、電線一本一本を加工して生産していくことから、多数の工程を要し、多大な労力と時間が掛かる。そのため、生産の自動化を図ることが重要である。 In FIG. 10, a wire harness 43 is a bundle of electric wires 44 and is routed to a predetermined position of an automobile (moving body) to transmit electric power and signals. The number of electric wires required for an automobile, including so-called popular cars and high-end cars, may be from several hundred to over 1,000 in some cases. Since such a wire harness 43 is produced by processing each electric wire one by one, it requires a large number of steps and takes a lot of labor and time. Therefore, it is important to automate production.
　ワイヤハーネス４３は、自動車に搭載される機器（車載電装品）の配置に応じて生産される。ワイヤハーネス４３の種類としては、例えば前側からあげると、エンジンルーム用ワイヤハーネス、カウルサイド用ワイヤハーネス、インストルメントパネル用ワイヤハーネス、ドア用ワイヤハーネス、リアサイド用ワイヤハーネス等がある。 The wire harness 43 is produced according to the arrangement of equipment (on-vehicle electrical components) mounted on the automobile. Examples of the wire harness 43 include, from the front side, an engine room wire harness, a cowl side wire harness, an instrument panel wire harness, a door wire harness, and a rear side wire harness.
　ワイヤハーネス４３は、電線４４の束であって、束の部分の構成としては、幹線４５と、この幹線４５の所定位置から分岐する複数の枝線４６とを有する。幹線４５や複数の枝線４６の端末には、様々な種類のコネクタ４７が設けられる。コネクタ４７は、電線４４の端末に取り付けられた端子金具と、この端子金具を収容するコネクタハウジングとを有する。 The wire harness 43 is a bundle of electric wires 44, and includes a main line 45 and a plurality of branch lines 46 branched from a predetermined position of the main line 45 as a configuration of the bundle part. Various types of connectors 47 are provided at the terminals of the main line 45 and the plurality of branch lines 46. The connector 47 includes a terminal fitting attached to the end of the electric wire 44 and a connector housing that accommodates the terminal fitting.
　ワイヤハーネス４３において、電気的な接続を確実にするためには、電線４４の端末の端子金具がコネクタハウジングの所定位置に挿入される必要がある。実施例では、電線４４の端末４８に、図１１に示すような識別のための意匠部分、すなわち着色部４９が形成される。尚、電線４４の端末に関し、ここでの説明では引用符号４８とするが、電線４４を検尺・切断した後は、後述する引用符号６６、６７で示す。 In the wire harness 43, in order to ensure electrical connection, the terminal fitting of the end of the electric wire 44 needs to be inserted into a predetermined position of the connector housing. In the embodiment, a design portion for identification as shown in FIG. 11, that is, a colored portion 49 is formed at the terminal 48 of the electric wire 44. In addition, regarding the terminal of the electric wire 44, it is set as the reference numeral 48 in the description here, but after the electric wire 44 is measured and cut, it is indicated by reference numerals 66 and 67 described later.
　図１１（ａ）において、先ず電線４４の構成について説明する。電線４４は、電線導体部５０（導体）と、電線被覆部５１（絶縁体）とを備える。電線導体部５０は、導電性を有する。電線被覆部５１は、絶縁性を有する。電線被覆部５１は、電線導体部５０の外表面に無着色の溶融樹脂材料を押し出すことにより形成される。電線被覆部５１は、樹脂材料に白色の着色剤を混入させて白色になる。又は、樹脂材料に着色剤を混入させてないでナチュラルな色になる。尚、電線被覆部５１の色は、実施例においては白色を原則とするが、ナチュラルやその他の色であってもよい。 11A, the configuration of the electric wire 44 will be described first. The electric wire 44 includes an electric wire conductor portion 50 (conductor) and an electric wire covering portion 51 (insulator). The electric wire conductor part 50 has electroconductivity. The electric wire covering part 51 has insulating properties. The wire covering portion 51 is formed by extruding an uncolored molten resin material on the outer surface of the wire conductor portion 50. The wire covering portion 51 becomes white by mixing a white colorant into the resin material. Or it becomes a natural color without mixing the coloring agent in the resin material. The color of the wire covering portion 51 is basically white in the embodiment, but may be natural or other colors.
　次に、着色部４９について説明する。着色部４９は、白色となる電線被覆部５１の外表面に形成される。着色部４９は、外表面の所定エリアに、また、全周にわたって形成される。着色部４９は、着色材で電線被覆部５１の外表面を着色することにより形成される。 Next, the coloring part 49 will be described. The colored portion 49 is formed on the outer surface of the wire covering portion 51 that becomes white. The colored portion 49 is formed in a predetermined area on the outer surface and over the entire circumference. The coloring portion 49 is formed by coloring the outer surface of the wire covering portion 51 with a coloring material.
　図１１（ｂ）、１１（ｃ）において、引用符号ａｒ１とａｒ２との間が第一エリア、引用符号ａｒ２とａｒ３との間が第二エリア、引用符号ａｒ３とａｒ４との間が第三エリア、引用符号ａｒ５とａｒ６との間が第四エリア、引用符号ａｒ６とａｒ７との間が第五エリア、引用符号ａｒ７とａｒ８との間が第六エリアとする。すると、図１１（ｂ）の着色部４９は、第三エリアと、第二エリアの半分に跨って、また、第六エリアと、第五エリアの半分に跨って形成される。一方、図１１（ｃ）の着色部４９の場合は、第一エリアと第三エリアとにそれぞれ、また、第四エリアと第六エリアとにそれぞれ形成される。尚、着色部４９の形成方法は、ここでの説明に限定されない。着色部４９を識別可能であれば、数や幅などを適宜変更してもよい。また、着色部４９は、周方向に線状（帯状）でなく、ドットやマーク等であってもよい。 11B and 11C, the first area is between the quotation marks ar1 and ar2, the second area is between the quotation marks ar2 and ar3, and the third area is between the quotation marks ar3 and ar4. The fourth area is between the quotation marks ar5 and ar6, the fifth area is between the quotation marks ar6 and ar7, and the sixth area is between the quotation marks ar7 and ar8. Then, the colored portion 49 in FIG. 11B is formed across the third area and half of the second area, and across the sixth area and half of the fifth area. On the other hand, in the case of the colored portion 49 of FIG. 11C, it is formed in the first area and the third area, respectively, and in the fourth area and the sixth area. In addition, the formation method of the coloring part 49 is not limited to description here. As long as the coloring part 49 can be identified, the number and width may be changed as appropriate. Moreover, the coloring part 49 may be a dot, a mark, etc. instead of linear (strip | belt shape) in the circumferential direction.
　着色部４９の色としては、Ｗ／Ｂ（ホワイト／ブラック）、Ｂ（ブラック）、Ｒ（レッド）、Ｌ（ブルー）、Ｌｇ（ライトグリーン）、Ｇ（グリーン）、Ｙ（イエロー）、Ｖ（バイオレット）、Ｐ（ピンク）、Ｓｂ（スカイブルー）、Ｂｒ（ブラウン）などが挙げられる。着色部４９の色に関しては、白色の電線被覆部５１に対して識別が可能であれば、また、他色と識別が可能であれば特に問題ない。 As colors of the colored portion 49, W / B (white / black), B (black), R (red), L (blue), Lg (light green), G (green), Y (yellow), V ( Violet), P (pink), Sb (sky blue), Br (brown) and the like. The color of the colored portion 49 is not particularly problematic as long as it can be identified with respect to the white wire covering portion 51 and can be distinguished from other colors.
　図９に示すように、第一システム構成群３６に着色ユニット４０が設け、第一システム構成群３６において着色部４９が形成される。先ず、第一システム構成群３６について説明をする。 As shown in FIG. 9, a coloring unit 40 is provided in the first system configuration group 36, and a coloring portion 49 is formed in the first system configuration group 36. First, the first system configuration group 36 will be described.
　図１２に示すように、第一システム構成群３６は、自動サブセット切断機５２と、第一自動サブセット圧着ライン５３と、第二自動サブセット圧着ライン５４とを備える。自動サブセット切断機５２と、第一自動サブセット圧着ライン５３と、第二自動サブセット圧着ライン５４は、図１２の紙面左から右へと連続するように配設される。第一自動サブセット圧着ライン５３と第二自動サブセット圧着ライン５４との違いは、主に着色ユニット４０の有無であり、着色ユニット４０は第一自動サブセット圧着ライン５３に組み込まれる。 As shown in FIG. 12, the first system configuration group 36 includes an automatic subset cutting machine 52, a first automatic subset crimping line 53, and a second automatic subset crimping line 54. The automatic subset cutting machine 52, the first automatic subset crimping line 53, and the second automatic subset crimping line 54 are arranged so as to be continuous from the left to the right of FIG. The difference between the first automatic subset crimping line 53 and the second automatic subset crimping line 54 is mainly the presence or absence of the coloring unit 40, and the coloring unit 40 is incorporated in the first automatic subset crimping line 53.
　図１３に示すように、自動サブセット切断機５２は、この装置裏側５５に複数種の電線リール５６（５６ａ－５６ｅ）を有する。言い換えれば、電線種別の異なる電線リール５６が複数設けられる。「電線種別の異なる」とは、例えば電線リール５６毎に太さ等が異なる電線４４が巻かれるなどを意味する。尚、図中の電線リール５６の数（実施例では五つ図示）は一例である。電線リール５６の数は、少なくともサブハーネス生産に必要な電線種別の分だけある。 As shown in FIG. 13, the automatic subset cutting machine 52 has a plurality of types of electric wire reels 56 (56a-56e) on the back side 55 of the apparatus. In other words, a plurality of wire reels 56 having different wire types are provided. “Different types of electric wires” means that, for example, electric wires 44 having different thicknesses are wound around the electric wire reels 56. The number of wire reels 56 (five shown in the embodiment) in the figure is an example. There are at least as many wire reels 56 as there are wire types necessary for sub-harness production.
　電線端末集合部５７は、各電線リール５６から引き出された電線４４（４４ａ－４４ｅ）の各電線端末４８（４８ａ－４８ｅ）を集める部分として設けられる。また、電線端末集合部５７は、各電線端末４８を各々保持するための部分としても設けられる。電線端末集合部５７は、電線４４の引き出しが可能な程度の保持力を有する。或いは、電線端末集合部５７は、電線４４の引き出しが必要な時に保持が解除されるような機構を有する。各電線端末４８の位置が揃えられた状態で電線端末集合部５７に保持される。 The wire terminal gathering portion 57 is provided as a portion for collecting the wire terminals 48 (48a-48e) of the wires 44 (44a-44e) drawn from the wire reels 56. Moreover, the electric wire terminal aggregate | assembly part 57 is provided also as a part for hold | maintaining each electric wire terminal 48, respectively. The wire terminal assembly portion 57 has a holding force that allows the wire 44 to be pulled out. Alternatively, the wire terminal assembly portion 57 has a mechanism that releases the holding when the wire 44 needs to be pulled out. The electric wire terminals 48 are held by the electric wire terminal assembly 57 in a state where the positions of the electric wire terminals 48 are aligned.
　自動サブセット切断機５２は、選択電線引出部５８と、検尺部５９と、電線切断部６０と、電線Ｕ字状セット部６１と、電線保持竿６２と、電線保持竿移動部６３とを備える。選択電線引出部５８では、一つのサブハーネスを構成する電線種別に基づき電線４４が選択され、この選択された電線４４が選択電線６４として電線端末集合部５７から自動で引き出される。選択電線引出部５８は、電線保持竿６２の移動方向（矢印Ｐ参照。生産工程の進行方法と同じ）に対して直交する方向（矢印Ｑ参照）に電線４４（選択電線６４）を自動で引き出すことができる機構を有する。 The automatic subset cutting machine 52 includes a selected electric wire drawing portion 58, a measuring portion 59, an electric wire cutting portion 60, an electric wire U-shaped set portion 61, an electric wire holding rod 62, and an electric wire holding rod moving portion 63. . In the selected electric wire lead-out portion 58, the electric wire 44 is selected based on the type of electric wire constituting one sub-harness, and the selected electric wire 44 is automatically drawn out from the electric wire terminal assembly portion 57 as the selected electric wire 64. The selected electric wire drawing portion 58 automatically draws the electric wire 44 (the selected electric wire 64) in a direction (see an arrow Q) orthogonal to the moving direction of the electric wire holding rod 62 (see the arrow P. The same as the method of progress of the production process). It has a mechanism that can.
　選択電線引出部５８により引き出された電線４４（選択電線６４）は、検尺部５９によりその引き出し長さが自動で検尺される。尚、引き出し長さは、サブハーネスの内容に応じ予めプログラミングされた数値に基づく。すなわち、配索に必要な長さを確保しなければならないことから、長く引き出すこともあれば逆に短く引き出すこともある。引き出された電線４４（選択電線６４）は、検尺部５９の検尺に基づいて所望の長さで切断される。この切断は電線切断部６０により行われ、切断によって検尺切断電線６５が得られる。 The lead length of the electric wire 44 (selected electric wire 64) drawn by the selected electric wire drawing portion 58 is automatically measured by the measuring portion 59. The drawer length is based on a value programmed in advance according to the contents of the sub-harness. In other words, since the length necessary for the wiring must be secured, the cable may be drawn out longer or may be drawn out shorter. The drawn electric wire 44 (selected electric wire 64) is cut to a desired length based on the measurement of the measurement unit 59. This cutting is performed by the electric wire cutting unit 60, and the cut and cut electric wire 65 is obtained by cutting.
　電線Ｕ字状セット部６１は、選択電線引出部５８による電線４４（選択電線６４）の引き出しに伴って作動する。電線Ｕ字状セット部６１の作動により、検尺切断電線６５の両端末６６、６７は、電線保持竿６２の所望の位置に各々セットされる。また、検尺切断電線６５は、この全体が電線保持竿６２に対し略Ｕ字状にセットされる。 The electric wire U-shaped set part 61 operates as the electric wire 44 (selected electric wire 64) is drawn by the selected electric wire drawing part 58. By the operation of the electric wire U-shaped setting portion 61, both ends 66 and 67 of the scale cut electric wire 65 are set at desired positions of the electric wire holding rod 62. Further, the entire cut-cut electric wire 65 is set in a substantially U shape with respect to the electric wire holding rod 62.
　ここで、電線Ｕ字状セット部６１について更に詳しく説明をする。電線Ｕ字状セット部６１は、矢印Ｑ方向に引き出された選択電線６４を略Ｕ字状にすることができる機構などを有する。特に図示しないが、具体的には、先ず引き出しのタイミングに合わせて選択電線６４の端末６６（引き出し先端側の端末）を保持しつつ端末６６の向きを１８０度反転させる第一の機構と、次に矢印Ｑ方向に引き出され電線切断部６０により切断された検尺切断電線６５の端末６７（引き出し後端側の端末）を保持する第二の機構と、上記の如く向きを反転させた端末６６を電線保持竿６２の所望の位置まで運んでセットする第三の機構と、端末６７を電線保持竿６２の所望の位置まで運んでセットする第四の機構とを備える。 Here, the electric wire U-shaped set part 61 will be described in more detail. The electric wire U-shaped set portion 61 includes a mechanism that can make the selected electric wire 64 drawn in the direction of the arrow Q into a substantially U shape. Although not specifically shown, specifically, a first mechanism that first reverses the orientation of the terminal 66 by 180 degrees while holding the terminal 66 (terminal on the leading end side of the drawer) of the selected electric wire 64 in accordance with the timing of drawing, To the second mechanism for holding the terminal 67 (terminal on the rear end side of the lead) of the scale-cutting electric wire 65 drawn in the direction of the arrow Q and cut by the electric wire cutting part 60, and the terminal 66 whose direction is reversed as described above. And a fourth mechanism for carrying and setting the terminal 67 to a desired position of the electric wire holding rod 62.
　電線Ｕ字状セット部６１の第一の機構は、先ず選択電線６４の端末６６の位置に合わせて配置され、端末６６を保持したと同時に向きを１８０度反転させつつ隣りに（矢印Ｐ方向に）ずれるような動作をする。第一の機構の向きが１８０度反転すると、端末６６の向きも１８０度反転の状態、すなわち矢印Ｑの逆方向の向きになることから、選択電線６４はこの端末６６の近くに略Ｕ字状の反転部分を有するようになる。反転部分は、選択電線６４の引き出しに伴って矢印Ｑ方向に移動するようになる（選択電線６４の反転部分は、第一の機構から離間するようになる）。 The first mechanism of the electric wire U-shaped set portion 61 is first arranged in accordance with the position of the terminal 66 of the selected electric wire 64, and while holding the terminal 66, at the same time the direction is reversed by 180 degrees (in the direction of arrow P). ) Behave like it is out of sync. When the direction of the first mechanism is reversed by 180 degrees, the direction of the terminal 66 is also reversed by 180 degrees, that is, the direction opposite to the arrow Q, so that the selected electric wire 64 is substantially U-shaped near the terminal 66. It has an inversion part. The reverse portion moves in the direction of arrow Q as the selected electric wire 64 is pulled out (the reverse portion of the selected electric wire 64 comes away from the first mechanism).
　電線Ｕ字状セット部６１の第二の機構は、第一の機構の移動（上記の隣へのずれ）に伴って、引き出し状態にある選択電線６４の位置に移動する動作をするとともに、電線切断部６０により切断されて得られた検尺切断電線６５の端末６７を保持する動作をする。 The second mechanism of the electric wire U-shaped set portion 61 operates to move to the position of the selected electric wire 64 in the drawn-out state along with the movement of the first mechanism (shift to the adjacent side). The operation | movement which hold | maintains the terminal 67 of the scale cutting electric wire 65 obtained by cut | disconnecting by the cutting part 60 is performed.
　尚、電線保持竿６２に対する端末６６、６７のセット位置は、例えばワイヤハーネス組み立て時における電線同士の絡み合いの防止に配慮したり、サブハーネス生産時における端子金具挿入順に配慮したりすることが好ましい。具体的には、端末６６、６７は、図１２に模式的に示したように順々にセットしていくのではなく、図３のような位置にセットされることが好ましい。 In addition, it is preferable to consider the set position of the terminals 66 and 67 with respect to the electric wire holding rod 62 in consideration of, for example, prevention of the entanglement of the electric wires when assembling the wire harness, or in the order of inserting the terminal fittings in the production of the sub harness. Specifically, the terminals 66 and 67 are preferably set at positions as shown in FIG. 3 instead of being sequentially set as shown schematically in FIG.
　電線保持竿６２に対し全体が略Ｕ字状にセットされた検尺切断電線６５は、この両端末６６、６７が電線保持竿６２から所定の長さで突出するように保持される。また、検尺切断電線６５は、この両端末６６、６７が電線保持竿６２の移動方向（矢印Ｐ参照）に対し直交するとともに、矢印Ｑの引き出し方向に対しては反対になる方向（後述するＱ′方向と同じ）に突出するように保持される。更に、検尺切断電線６５は、この両端末６６、６７が着色ユニット４０の配置側や、端末皮むき部６８及び端子取付部６９（図１２参照）の配置側に突出するように保持される。別な言い方をすれば、端末６６、６７は、着色ユニット４０や端末皮むき部６８を通過する位置に保持される。 Measured cut electric wire 65, which is generally set in a U shape with respect to electric wire holding rod 62, is held such that both ends 66 and 67 protrude from electric wire holding rod 62 with a predetermined length. The scale cutting electric wire 65 has both ends 66 and 67 orthogonal to the moving direction of the electric wire holding rod 62 (see arrow P) and opposite to the drawing direction of the arrow Q (described later). (Same as Q 'direction). Further, the scale cutting electric wire 65 is held such that both ends 66 and 67 protrude to the arrangement side of the coloring unit 40 and the arrangement side of the terminal peeling portion 68 and the terminal mounting portion 69 (see FIG. 12). . In other words, the terminals 66 and 67 are held at positions that pass through the coloring unit 40 and the terminal peeling portion 68.
　電線保持竿６２は、矢印Ｐ方向に長尺な竿状の部材であって、矢印Ｐに対し直交する方向に複数のスリットを有する。この複数のスリットは、電線保持部として形成される。電線保持竿６２は、特に図示しないが、自動サブセット切断機５２の近傍にストックされ、サブハーネス生産に合わせて電線保持竿移動部６３に供給される。 The wire holding rod 62 is a bowl-shaped member that is long in the direction of the arrow P, and has a plurality of slits in the direction orthogonal to the arrow P. The plurality of slits are formed as electric wire holding portions. Although not particularly shown, the wire holding rod 62 is stocked in the vicinity of the automatic subset cutting machine 52, and is supplied to the wire holding rod moving unit 63 in accordance with sub-harness production.
　電線保持竿６２の構造についてより詳しく説明する。電線保持竿６２は、矢印Ｐ方向に並ぶ数多くの電線クリップと、この電線クリップを長尺な竿状の状態にしておくクリップベースとを備える。電線クリップは、一対の挟持子から構成され、この一対の挟持子の間が電線保持部として形成される。一対の挟持子の先端部分には、電線案内用としてテーパが形成される。テーパは、電線保持部に向けて傾斜するように形成される。電線クリップは、全て同じ大きさ及び形状に形成される。電線クリップは、一つの電線保持竿６２に数十個存在するように設けられる。 The structure of the wire holding rod 62 will be described in more detail. The electric wire holding rod 62 includes a number of electric wire clips arranged in the direction of the arrow P and a clip base that keeps the electric wire clip in a long hook shape. An electric wire clip is comprised from a pair of clamping element, and between this pair of clamping elements is formed as an electric wire holding part. A taper is formed at the tip portion of the pair of sandwiching elements for guiding the electric wire. The taper is formed so as to incline toward the electric wire holding part. The electric wire clips are all formed in the same size and shape. The electric wire clip is provided so that several tens of electric wire clips exist in one electric wire holding rod 62.
　尚、実施例の場合、電線保持竿６２の例えば一端から何番目の電線クリップに、どのような電線種別の検尺切断電線６５が保持されるのかが予めサブハーネスの内容に応じてプログラミングされている。 In the case of the embodiment, for example, what number of electric wire clips from one end of the electric wire holding rod 62 is held in advance is programmed according to the contents of the sub-harness. Yes.
　電線保持竿移動部６３は、複数の検尺切断電線６５が保持された状態の電線保持竿６２を、着色ユニット４０や後述する端末皮むき部６８及び端子取付部６９（図１２参照）へ向けて搬送することができるような機構を有する。具体的には、電線保持竿移動部６３は、電線保持竿６２を矢印Ｐ方向に案内するレール状の部分と、電線保持竿６２を矢印Ｐ方向に所定のスピードで移動させる機構とを有する。尚、電線保持竿移動部６３は、実施例では、検尺切断電線６５のセット中に電線保持竿６２の移動が生じないように制御されている。 The electric wire holding rod moving part 63 directs the electric wire holding rod 62 in a state in which the plurality of scale-cutting electric wires 65 are held to the coloring unit 40, a terminal peeling portion 68 and a terminal mounting portion 69 (see FIG. 12) described later. It has a mechanism that can be conveyed. Specifically, the electric wire holding rod moving part 63 has a rail-shaped portion that guides the electric wire holding rod 62 in the direction of arrow P, and a mechanism that moves the electric wire holding rod 62 in the direction of arrow P at a predetermined speed. In the embodiment, the electric wire holding rod moving part 63 is controlled so that the electric wire holding rod 62 does not move during the setting of the scale cut electric wire 65.
　レール状の部分は、自動サブセット切断機５２のみならず、第一自動サブセット圧着ライン５３及び第二自動サブセット圧着ライン５４にまで跨るように配設される。 The rail-shaped portion is arranged not only to the automatic subset cutting machine 52 but also to the first automatic subset crimping line 53 and the second automatic subset crimping line 54.
　自動サブセット切断機５２により、検尺切断電線６５をサブハーネス生産に必要な電線種別分及び数分まとめて第一自動サブセット圧着ライン５３へ流すことができる（複数の検尺切断電線６５をまとめた状態としては図３も参照）。 The automatic subset cutting machine 52 can flow the cut and cut electric wires 65 into the first automatic subset crimping line 53 for the type and number of wires necessary for the production of the sub-harness (a plurality of the cut electric wires 65 are collected). See also FIG. 3 for the state).
　図１２に示すように、第一自動サブセット圧着ライン５３は、着色ユニット４０と、端末皮むき部６８と、端子取付部６９とを備える。第一自動サブセット圧着ライン５３は、着色ユニット４０が組み込まれたラインである。 As shown in FIG. 12, the first automatic subset crimping line 53 includes a coloring unit 40, a terminal peeling portion 68, and a terminal attachment portion 69. The first automatic subset crimping line 53 is a line in which the coloring unit 40 is incorporated.
　先ず、着色ユニット４０について、図１４―１７を順に参照しながら説明をする。 First, the coloring unit 40 will be described with reference to FIGS. 14-17 in order.
　図１４に示すように、着色ユニット４０は、電線保持竿６２に対し全体が略Ｕ字状にセットされた検尺切断電線６５の両端末６６、６７が突出する側に配置される。すなわち、着色ユニット４０は、両端末６６、６７の所望の位置（所望のエリア）に着色材にて着色することができるように配置及び構成される。 As shown in FIG. 14, the coloring unit 40 is arranged on the side from which both ends 66 and 67 of the scale cutting electric wire 65 set in a substantially U shape with respect to the electric wire holding rod 62 protrude. That is, the coloring unit 40 is arranged and configured so that the desired position (desired area) of both terminals 66 and 67 can be colored with the coloring material.
　ここで「着色する」について説明をする。この「着色する」とは、端末６６、６７（図１１の電線被覆部５１参照。以下同様）の外表面を着色材で着色することを示す。着色材とは、色材（工業用有機物質）が水又はその他の溶媒に熔解、分散した液状物質である。有機物質としては、染料、顔料（大部分は有機物であり、合成品）があり、時には染料が顔料として、顔料が染料として用いられることもある。より具体的な例としては、着色材とは、着色液または塗料である。 Here, “coloring” will be explained. This “coloring” indicates that the outer surfaces of the terminals 66 and 67 (see the electric wire covering portion 51 in FIG. 11; the same applies hereinafter) are colored with a coloring material. The coloring material is a liquid material in which a coloring material (industrial organic material) is dissolved and dispersed in water or other solvent. Examples of organic substances include dyes and pigments (mostly organic substances and synthetic products), and sometimes dyes are used as pigments and pigments are used as dyes. As a more specific example, the coloring material is a coloring liquid or a paint.
　着色液とは、溶媒中に染料が溶けているもの、又は分散しているものを示す。また、塗料とは、分散液中に顔料が分散しているものを示す。そのため、着色液で端末６６、６７（電線被覆部５１）の外表面を着色すると、染料が端末６６、６７（電線被覆部５１）内に染み込む。また、塗料で端末６６、６７（電線被覆部５１）の外表面を着色すると、顔料が端末６６、６７（電線被覆部５１）内に染み込むことなく外表面に接着する。すなわち、ここで言う「着色する」とは、端末６６、６７（電線被覆部５１）の外表面を染料で染めること、または、端末６６、６７（電線被覆部５１）の外表面に顔料を塗ることを示す。 Colored liquid refers to those in which a dye is dissolved or dispersed in a solvent. Moreover, a coating material shows what the pigment has disperse | distributed in the dispersion liquid. Therefore, when the outer surfaces of the terminals 66 and 67 (the electric wire covering portion 51) are colored with the coloring liquid, the dye soaks into the terminals 66 and 67 (the electric wire covering portion 51). Further, when the outer surfaces of the terminals 66 and 67 (the electric wire covering portion 51) are colored with paint, the pigment adheres to the outer surface without penetrating into the terminals 66 and 67 (the electric wire covering portion 51). That is, “coloring” as used herein means dyeing the outer surfaces of the terminals 66 and 67 (the electric wire covering portion 51) with a dye, or applying a pigment to the outer surfaces of the terminals 66 and 67 (the electric wire covering portion 51). It shows that.
　溶媒と分散液に関し、端末６６、６７（電線被覆部５１）を形成する合成樹脂材料と親和性のあるものが望ましい。この場合、染料が端末６６、６７（電線被覆部５１）内に確実に染み込んだり、顔料が端末６６、６７（電線被覆部５１）の外表面に確実に接着することになる。 As for the solvent and the dispersion liquid, those having affinity with the synthetic resin material forming the terminals 66 and 67 (the wire covering portion 51) are desirable. In this case, the dye surely soaks into the terminals 66 and 67 (the electric wire covering part 51), and the pigment adheres securely to the outer surface of the terminals 66 and 67 (the electric wire covering part 51).
　着色ユニット４０は、端末拭き取り部７０（拭き取り部）と、着色ユニット本体部７１と、乾燥部７２と、意匠確認部７３とを備えて構成される。着色ユニット４０は、本実施例において、上記構成を一纏めにしてなる装置である（一例である。上記構成を一つ一つの装置として適宜間隔で並べて着色ユニット４０としてもよい）。着色ユニット４０は、制御部(不図示)にて制御される。制御部には、検尺切断電線６５の電線種別や、電線保持竿６２における端末６６（６７）の配置など、着色ユニット４０の作動に必要な情報が予めプログラミングされている。 The coloring unit 40 includes a terminal wiping unit 70 (wiping unit), a coloring unit main body 71, a drying unit 72, and a design confirmation unit 73. In this embodiment, the coloring unit 40 is an apparatus in which the above-described configurations are grouped together (an example. The above-described configuration may be arranged as an apparatus at appropriate intervals to form the coloring unit 40). The coloring unit 40 is controlled by a control unit (not shown). Information necessary for the operation of the coloring unit 40, such as the wire type of the measuring wire 65 and the arrangement of the terminal 66 (67) in the wire holding rod 62, is programmed in the control unit in advance.
　図１５に示すように、端末拭き取り部７０は、電線保持竿６２に対し全体が略Ｕ字状にセットされた検尺切断電線６５の端末６６（６７）の汚れを自動で拭き取るために備えられる。実施例では、端末拭き取り部７０を備えることにより、端末６６（６７）への着色状態を良好にすることをねらう。 As shown in FIG. 15, the terminal wiping portion 70 is provided for automatically wiping off the dirt of the terminal 66 (67) of the scale-cutting electric wire 65 that is generally set in a U shape with respect to the electric wire holding rod 62. . In the embodiment, the terminal wiping unit 70 is provided to improve the coloring state of the terminal 66 (67).
　尚、図１５中の矢印Ｐは電線保持竿６２の移動方向を示す。矢印Ｑは自動サブセット切断機５２（図１３参照）での選択電線６４の引き出し方向を示す。矢印Ｑ′は検尺切断電線６５の端末６６（６７）の突出方向（のびる方向）を示す。矢印Ｒ及びＲ′は上下方向を示す。 Note that an arrow P in FIG. 15 indicates the moving direction of the wire holding rod 62. An arrow Q indicates a direction in which the selected electric wire 64 is pulled out by the automatic subset cutting machine 52 (see FIG. 13). The arrow Q ′ indicates the protruding direction (extending direction) of the terminal 66 (67) of the measuring wire 65. Arrows R and R ′ indicate the vertical direction.
　端末拭き取り部７０は、一対の拭き取り部７４（端末拭き取り部本体）と、この一対の拭き取り部７４を移動させる第一の移動機構７５及び第二の移動機構７６と電線チャック部(不図示)とを備える。一対の拭き取り部７４は、端末６６（６７）を上下から挟み込んで接触した後、外表面全体を擦るように移動することができる部分として形成される。一対の拭き取り部７４は、この外周面が拭き取りに使用される。本実施例において、芯材を布で覆った部分として形成される。芯材は、円柱形状、角柱形状等、適宜選定される。 The terminal wiping portion 70 includes a pair of wiping portions 74 (terminal wiping portion main body), a first moving mechanism 75 and a second moving mechanism 76 for moving the pair of wiping portions 74, and an electric wire chuck portion (not shown). Is provided. The pair of wiping portions 74 are formed as portions that can move so as to rub the entire outer surface after the terminal 66 (67) is sandwiched and contacted from above and below. As for a pair of wiping off part 74, this outer peripheral surface is used for wiping off. In this embodiment, the core material is formed as a portion covered with a cloth. The core material is appropriately selected from a cylindrical shape, a prismatic shape, and the like.
　尚、一対の拭き取り部７４は、常に同じ箇所で端末６６（６７）の外表面全体を擦って汚れを拭き取るのではなく、適宜タイミングで拭き取り箇所を変えることができるような構成を有することが好ましい（例えば、拭き取り部外周面を回転方向に移動させて拭き取り箇所を変更するなど）。 In addition, it is preferable that the pair of wiping portions 74 have a configuration in which the wiping location can be changed at an appropriate timing, instead of always wiping the entire outer surface of the terminal 66 (67) at the same location and wiping the dirt. (For example, changing the wiping location by moving the outer peripheral surface of the wiping portion in the rotation direction).
　第一の移動機構７５及び第二の移動機構７６は、拭き取りに必要な動作として、一対の拭き取り部７４を矢印Ｒ、Ｒ′方向に移動させるとともに、矢印Ｑ、Ｑ′方向に移動させることができるように構成される。 The first moving mechanism 75 and the second moving mechanism 76 can move the pair of wiping portions 74 in the directions of arrows R and R ′ and move in the directions of arrows Q and Q ′ as operations necessary for wiping. Configured to be able to.
　一対の拭き取り部７４による拭き取りの最中は、電線チャック部(不図示)が検尺切断電線６５を保持して端末位置ズレを防止する。 During the wiping by the pair of wiping parts 74, the electric wire chuck part (not shown) holds the measured cutting electric wire 65 to prevent terminal position deviation.
　端末拭き取り部７０は、端末６６（６７）の汚れを拭き取る機能だけでなく、端末６６（６７）を真っ直ぐにのばす機能も有する。端末６６（６７）を真っ直ぐにのばすことで、着色位置の安定に寄与することができる、また、端子金具８９を正確な位置に取り付けることもできる。 The terminal wiping unit 70 has not only a function of wiping dirt on the terminal 66 (67) but also a function of extending the terminal 66 (67) straight. By extending the terminal 66 (67) straight, it is possible to contribute to the stability of the coloring position, and it is also possible to attach the terminal fitting 89 to an accurate position.
　端末拭き取り部７０は、拭き取りを行うことから、着色時の「にじみ」を防止することができるという利点を有する。また、端末拭き取り部７０は、検尺切断電線６５の全体に対し拭き取りをするものでなく、着色に必要な部分のみの拭き取り（一定範囲の拭き取り）をする。このため、端末拭き取り部７０は、拭き取りに掛かる時間が短く、また、装置の耐久性（拭き取り部７４の耐久性）も良いという利点を有する。 Since the terminal wiping unit 70 performs wiping, the terminal wiping unit 70 has an advantage that “bleeding” during coloring can be prevented. In addition, the terminal wiping unit 70 does not wipe the entire scale-cutting electric wire 65 but wipes only a portion necessary for coloring (wiping within a certain range). For this reason, the terminal wiping unit 70 has an advantage that the time required for wiping is short and the durability of the device (the durability of the wiping unit 74) is also good.
　尚、拭き取りに関し、着色に必要な部分のみの拭き取りで済むのは、矢印Ｐ方向に移動する検尺切断電線６５に対し、この端末６６（６７）が矢印Ｑ′方向に突出するからである。 The reason for wiping off only the portion necessary for coloring is that the terminal 66 (67) protrudes in the direction of the arrow Q 'with respect to the measuring wire 65 that moves in the direction of the arrow P.
　図１６に示すように、着色ユニット本体部７１は、電線保持竿６２に対し全体が略Ｕ字状にセットされた検尺切断電線６５の端末６６（６７）に、識別用の意匠部分として着色部４９を自動で形成するために備えられる。着色ユニット本体部７１は、実施例では、端末６６（６７）の外表面における所定エリアに着色材７７を吹き付けて着色部４９の形成をすることができるように構成される。 As shown in FIG. 16, the coloring unit main body 71 is colored as a design portion for identification on the terminal 66 (67) of the measuring wire 65 that is set in a substantially U shape with respect to the wire holding rod 62. It is provided for automatically forming the portion 49. In the embodiment, the coloring unit main body 71 is configured such that the coloring portion 49 can be formed by spraying the coloring material 77 onto a predetermined area on the outer surface of the terminal 66 (67).
　着色ユニット本体部７１は、着色ヘッド７８と、この着色ヘッド７８を移動させる第一の移動機構７９及び第二の移動機構８０と、電線チャック部(不図示)と、ノズル洗浄部(不図示)と、着色材供給部(不図示)とを備える。着色ヘッド７８は、着色ヘッド本体８１と、この着色ヘッド本体８１から端末６６（６７）の外表面における所定エリアに着色材７７を吹き付けるための複数の着色ノズル８２とを備える。 The coloring unit main body 71 includes a coloring head 78, a first moving mechanism 79 and a second moving mechanism 80 for moving the coloring head 78, an electric wire chuck portion (not shown), and a nozzle cleaning portion (not shown). And a coloring material supply unit (not shown). The coloring head 78 includes a coloring head main body 81 and a plurality of coloring nozzles 82 for spraying the coloring material 77 from the coloring head main body 81 to a predetermined area on the outer surface of the terminal 66 (67).
　着色ノズル８２は、実施例では、１２色分の吐出が可能な数だけ設けられる。複数の着色ノズル８２は、矢印Ｑ及びＱ′方向に一列に並んで配置される。複数の着色ノズル８２は、着色部４９の色に応じて使い分けられる。使い分けは、着色ヘッド７８を第一の移動機構７９により矢印Ｑ及びＱ′方向に移動させることにより行われる。 In the embodiment, as many coloring nozzles 82 as possible are ejected for 12 colors. The plurality of coloring nozzles 82 are arranged in a line in the directions of arrows Q and Q ′. The plurality of coloring nozzles 82 are selectively used according to the color of the coloring portion 49. The proper use is performed by moving the coloring head 78 in the directions of arrows Q and Q ′ by the first moving mechanism 79.
　着色ヘッド７８は、検尺切断電線６５の端末６６（６７）に対し矢印Ｑ及びＱ′方向に移動する。また、着色ヘッド７８は、端末６６（６７）の外表面の全周にわたって着色部４９を形成するため、スイング（揺動または首振り）するような矢印Ｓ及びＳ′方向にも移動する。 The coloring head 78 moves in the directions of arrows Q and Q ′ with respect to the terminal 66 (67) of the measuring wire 65. The coloring head 78 also moves in the directions of arrows S and S ′ that swing (swing or swing) in order to form the colored portion 49 over the entire outer surface of the terminal 66 (67).
　着色ヘッド７８は、矢印Ｐ方向に移動する検尺切断電線６５に対し、また、矢印Ｑ′方向に突出する端末６６（６７）に対し、自身が移動して着色部４９を形成するように構成される。 The coloring head 78 is configured to move to the scale cutting electric wire 65 moving in the arrow P direction and to the terminal 66 (67) protruding in the arrow Q ′ direction to form the coloring portion 49. Is done.
　図１７（ａ）－１７（ｃ）を参照しながら着色材７７の付着状態を説明する。先ず、端末６６（６７）の外表面に対し着色材７７が付着しない位置では、着色材７７の噴射は行われない。次に、図１７（ａ）に示すように、矢印Ｓ方向に着色ヘッド７８を移動させて着色材７７が外表面に付着する位置になると、着色材７７の噴射が行われるようになる。尚、着色材７７は、加圧により噴射される（一例である）。着色材７７が外表面に付着し始めると、着色材７７は着色ヘッド７８から離れる側へ回り込み、図１７（ｂ）に示すような状態になる。 The adhesion state of the colorant 77 will be described with reference to FIGS. 17 (a) -17 (c). First, the colorant 77 is not jetted at a position where the colorant 77 does not adhere to the outer surface of the terminal 66 (67). Next, as shown in FIG. 17A, when the coloring head 78 is moved in the direction of arrow S to reach a position where the coloring material 77 adheres to the outer surface, the coloring material 77 is jetted. The coloring material 77 is injected by pressurization (an example). When the coloring material 77 starts to adhere to the outer surface, the coloring material 77 wraps around to the side away from the coloring head 78, resulting in a state as shown in FIG.
　端末６６（６７）に対し着色材７７が横切った後、図１７（ｃ）に示すように、着色ヘッド７８を矢印Ｓ′方向に移動させると、今度は逆側から着色材７７の回り込みが生じ、これにより全周にわたって着色材７７の付着が完了するようになる。 After the coloring material 77 crosses the terminal 66 (67), as shown in FIG. 17C, when the coloring head 78 is moved in the direction of the arrow S ′, the coloring material 77 wraps around from the opposite side. Thereby, the adhesion of the coloring material 77 is completed over the entire circumference.
　尚、より確実に全周に着色材７７を付着させようとするのであれば、例えば図１６の仮想線で示すように、着色ユニット本体部７１′を着色ユニット本体部７１の反対側に追加配置する例が挙げられる。矢印Ｐ方向に移動する検尺切断電線６５の妨げにならない配置であれば、着色ユニット本体部７１′の配置箇所は特に限定されない。 If the coloring material 77 is to be attached to the entire circumference more reliably, for example, as shown by the phantom line in FIG. 16, the coloring unit main body 71 ′ is additionally arranged on the opposite side of the coloring unit main body 71. An example is given. The arrangement location of the coloring unit main body 71 ′ is not particularly limited as long as it is an arrangement that does not hinder the measuring wire 65 that moves in the direction of the arrow P.
　この他、端末６６（６７）と着色ヘッド７８との間にマスク部材を介在させて、ドットやマーク（マーキング）を施せるような構成にしてもよい。 In addition, a mask member may be interposed between the terminal 66 (67) and the coloring head 78 so that dots or marks (marking) can be applied.
　また、着色部４９を幅広に形成したり、端末６６（６７）の全体を着色したりする場合には、着色ヘッド７８を矢印Ｓ及びＳ′方向に移動させながら矢印Ｑ′方向にも移動させ、連続的に着色材７７の吹きつけを行えばよい。 Further, when the coloring portion 49 is formed wide or the entire terminal 66 (67) is colored, the coloring head 78 is moved in the direction of the arrow Q 'while moving in the directions of the arrows S and S'. The colorant 77 may be sprayed continuously.
　図１４に示すように、乾燥部７２は、着色材７７（図１６参照）の吹き付けにより形成された着色部４９をヒータ等により乾かして定着させるために備えられる。また、意匠確認部７３は、着色部４９の形成状態や形成位置を、画像を撮影する等により検査するために備えられる。 As shown in FIG. 14, the drying section 72 is provided for drying and fixing the colored section 49 formed by spraying the coloring material 77 (see FIG. 16) with a heater or the like. Moreover, the design confirmation part 73 is provided in order to inspect the formation state and formation position of the coloring part 49 by taking an image or the like.
　次に、図１８を参照しながら端末皮むき部６８について説明をする。また、図１９を参照しながら端子取付部６９についても説明をする。 Next, the terminal peeling portion 68 will be described with reference to FIG. Further, the terminal attachment portion 69 will be described with reference to FIG.

In the terminal 66 (67) of the rear identification electric wire 88 (scale cut electric wire 65) having the coloring portion 49, the electric wire covering portion 51 is removed by a predetermined length by the terminal peeling portion 68. When the wire covering portion 51 is removed, the wire conductor portion 50 is exposed from the terminal 66 (67). Note that the terminal peeling portion 68 results in a state as shown in FIG.
　図１９に示すように、端子取付部６９は、電線導体部５０が露出する端末６６（６７）に端子金具８９を自動で取り付けるために備えられる。端子取付部６９は、実施例では、圧着により端子金具８９を取り付けることができるように構成される。また、端子取付部６９は、電線種別に対応するように複数種の端子金具８９を取り付けることができるように構成される。第一自動サブセット圧着ライン５３（図１２参照）では、六種類の端子金具８９の取り付けが可能である（これ以上の種類の端子金具８９の取り付けが必要であれば、第一自動サブセット圧着ライン５３と同様な第二自動サブセット圧着ライン５４が必要になる）。端子取付部６９には、複数種の端子金具８９が各々供給される。 As shown in FIG. 19, the terminal attachment portion 69 is provided for automatically attaching the terminal fitting 89 to the terminal 66 (67) where the electric wire conductor portion 50 is exposed. In the embodiment, the terminal attachment portion 69 is configured so that the terminal fitting 89 can be attached by pressure bonding. Moreover, the terminal attachment part 69 is comprised so that multiple types of terminal metal fittings 89 can be attached so that it may respond | correspond to electric wire classification. In the first automatic subset crimping line 53 (see FIG. 12), six types of terminal fittings 89 can be attached (if more types of terminal fittings 89 need to be attached, the first automatic subset crimping line 53 can be attached. A second automatic subset crimping line 54 is required). A plurality of types of terminal fittings 89 are supplied to the terminal mounting portion 69.
　尚、複数種の端子金具８９の取り付けに関し、端末６６（６７）の流れてくる順に各種の端子金具８９を取り付ける工程や、端子取付部６９を移動させて同じ種別の端子金具８９毎に取り付ける工程のいずれを採用してもよい。実施例では、端子金具８９は、取り付けの必要がある端末６６（６７）のみ行われる（この場合、図６に示すような状態になる）。 In addition, regarding the attachment of a plurality of types of terminal fittings 89, a step of attaching various terminal fittings 89 in the order in which the terminal 66 (67) flows, or a step of moving the terminal attachment portion 69 to attach each terminal fitting 89 of the same type. Any of these may be adopted. In the embodiment, the terminal fitting 89 is performed only on the terminal 66 (67) that needs to be attached (in this case, the state is as shown in FIG. 6).
　以上、図９―１９を参照しながら説明してきたように、第一システム構成群３６のシステム構成により、図６に示すような複数の端子付き後識別電線９（後識別電線群１０）が得られる。 As described above with reference to FIGS. 9-19, the system configuration of the first system configuration group 36 provides a plurality of post-identification wires 9 with terminals (rear-identification wire group 10) as shown in FIG.

　第一システム構成群３６では、検尺切断電線６５を電線保持竿６２に略Ｕ字状にセットすることから、この検尺切断電線６５の各端末６６、６７を突出させて一方向に向くようにすることができる。これにより、端末拭き取り部７０における一対の拭き取り部７４による拭き取り対象を各端末６６、６７のみの一定範囲にすることができる。従って、無駄に拭き取る部分を抑えて、一対の拭き取り部７４の耐久性を高めることができるという効果を奏する。また、常に一定範囲を拭き取りすればよいので、システムの制御を単純化することもできるという効果を奏する。この他、検尺切断電線６５の各端末６６、６７の拭き取りを着色直前において各々行うことから、着色状態を安定させることができ、より確実に「にじみ」を防止することができるという効果を奏する。 In the first system configuration group 36, the measuring wire 65 is set in the electric wire holding rod 62 in a substantially U shape, so that the terminals 66 and 67 of the measuring wire 65 are projected to face in one direction. Can be. Thereby, the wiping object by the pair of wiping portions 74 in the terminal wiping portion 70 can be set to a certain range of only the terminals 66 and 67. Therefore, there is an effect that it is possible to increase the durability of the pair of wiping portions 74 by suppressing the portion to be wiped uselessly. In addition, since it is sufficient to always wipe a certain range, the system control can be simplified. In addition, since each of the terminals 66 and 67 of the measuring wire 65 is wiped immediately before coloring, the colored state can be stabilized, and the “bleeding” can be prevented more reliably. .

Reference numeral 92 indicates a manual terminal insertion portion (terminal insertion portion). Reference numeral 93 indicates a joint portion between wires. Reference numeral 94 indicates a sub-harness continuity inspection unit.
　第三システム構成群４１では、自動機化が困難な工程が行われる。具体的には、第三システム構成群４１では、図８に示すような端子付き後識別電線９をツイストする工程が行われる。また、第三システム構成群４１では、第二システム構成群３７で自動挿入することができなかった端子金具（例えば、他と逆向きに挿入する場合など）を手動で挿入する工程が行われる。また、第三システム構成群４１では、電線同士をジョイントする工程が行われる。この他、第三システム構成群４１では、グロメットなどのような予め組み付けておいた方がよい外装部品を手動で組み付ける工程が行われる。そして、第三システム構成群４１では、最後にサブハーネス２（図８参照）の回路が間違いなくできているか否かを検査する工程が行われる。 In the third system configuration group 41, processes that are difficult to be automated are performed. Specifically, in the third system configuration group 41, a process of twisting the rear identification electric wire 9 with a terminal as shown in FIG. 8 is performed. Further, in the third system configuration group 41, a step of manually inserting a terminal metal fitting that could not be automatically inserted in the second system configuration group 37 (for example, when inserted in the opposite direction to the other) is performed. Moreover, in the 3rd system structure group 41, the process of jointing electric wires is performed. In addition, in the third system configuration group 41, a step of manually assembling exterior parts such as grommets that should be assembled in advance is performed. In the third system configuration group 41, finally, a step of inspecting whether or not the circuit of the sub-harness 2 (see FIG. 8) is definitely made is performed.

After tape winding and exterior parts are attached to the sub-harness 2 (see FIG. 8) set on the wiring board 95, the wire harness 43 (see FIG. A series of production and assembly up to reference) is completed.
　本発明は本発明の主旨を変えない範囲で種々変更実施可能である。 The present invention can be variously modified without departing from the spirit of the present invention.
　例えば、一種類の電線リールから引き出された一本の電線をローラで検尺しながら（長さを測定しながら）電線を引っ張り、検尺した値に応じて電線に着色を施し、その後に切断及び端子取付を行う一連の装置を有する生産システムにおいて、着色の前に電線を拭き取るようにしてもよい。この場合、拭き取り部を、検尺のローラと同じように電線に絶えず接触させてもよいが、検尺した値に応じて電線端末の着色位置を定めるのと同様に、検尺した値に応じて着色位置である電線端末のみを拭き取るようにしてもよい。また、検尺とは別に、拭き取りのためのローラ（測定）装置を設けてもよい。尚、検尺装置と着色装置と拭き取り部は一つの制御装置で制御されていることが前提である。 For example, while measuring a length of one wire drawn from one type of wire reel with a roller (while measuring the length), pull the wire, color the wire according to the measured value, and then cut And in a production system having a series of devices for attaching terminals, the wires may be wiped before coloring. In this case, the wiping part may be continuously in contact with the electric wire in the same manner as the measuring roller, but depending on the measured value, as well as determining the coloring position of the electric wire terminal according to the measured value. It is also possible to wipe only the wire terminal that is the coloring position. In addition to the measuring scale, a roller (measuring) device for wiping may be provided. It is assumed that the measuring device, the coloring device, and the wiping unit are controlled by a single control device.
　本発明によれば、着色ユニットを通過する電線に対し、この電線被覆部の拭き取りを行ってから着色をすることから、別な言い方をすれば、電線被覆部を着色材で着色する前に、電線被覆部に対して拭き取りを行うことから、着色材の「にじみ」を防止することができる。 According to the present invention, for the electric wire passing through the coloring unit, since the coloring is performed after wiping the electric wire covering portion, in other words, before coloring the electric wire covering portion with the coloring material, Since the electric wire covering portion is wiped off, “bleeding” of the coloring material can be prevented.
