[0001] 本発明は、導電性の芯線と、この芯線を被覆する絶縁性の被覆部とを備えた電線 を着色する電線の着色装置に関する。  The present invention relates to an electric wire coloring apparatus for coloring an electric wire having a conductive core wire and an insulating covering portion covering the core wire.
背景技術  Background art
[0002] 移動体としての自動車などには、種々の電子機器が搭載される。このため、前記自 動車などは、前記電子機器に電源などからの電力やコンピュータなどからの制御信 号などを伝えるために、ワイヤハーネスを配索している。ワイヤハーネスは、複数の電 線と、該電線の端部などに取り付けられたコネクタなどを備えている。  [0002] Various electronic devices are mounted on an automobile or the like as a moving body. For this reason, the vehicle and the like are wired with a wire harness to transmit power from a power source or the like or control signals from a computer or the like to the electronic device. The wire harness includes a plurality of electric wires and a connector attached to an end of the electric wire.
[0003] 電線は、導電性の芯線と該芯線を被覆する絶縁性の合成樹脂からなる被覆部とを 備えている。電線は、所謂被覆電線である。コネクタは、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備えている。端子金具は、導電性の板金などからなり 電線の端部に取り付けられてこの電線の芯線と電気的に接続する。コネクタハウジン グは、絶縁性の合成樹脂からなり箱状に形成されている。ワイヤハーネスは、コネクタ ハウジングが前述した電子機器などと結合することにより、端子金具を介して各電線 が前述した電子機器と電気的に接続して、前述した電子機器に所要の電力や信号 を伝える。  [0003] The electric wire includes a conductive core wire and a coating made of an insulating synthetic resin that covers the core wire. The electric wire is a so-called covered electric wire. The connector includes a terminal fitting and a connector housing for accommodating the terminal fitting. The terminal fitting is made of a conductive sheet metal or the like, and is attached to an end of the electric wire to be electrically connected to a core wire of the electric wire. The connector housing is made of insulating synthetic resin and is formed in a box shape. In the wiring harness, when the connector housing is connected to the above-mentioned electronic device, etc., each wire is electrically connected to the above-mentioned electronic device via terminal fittings, and transmits required power and signals to the above-mentioned electronic device. .
[0004] 前記ワイヤハーネスを組み立てる際には、まず電線を所定の長さに切断した後、該 電線の端部などの被覆部を除去 (皮むき）して端子金具を取り付ける。必要に応じて 電線同士を接続する。その後、端子金具をコネクタハウジング内に揷入する。こうして 、前述したワイヤハーネスを組み立てる。  [0004] When assembling the wire harness, first, the wire is cut into a predetermined length, and then a covering such as an end portion of the wire is removed (peeled) and a terminal fitting is attached. Connect the wires as necessary. Thereafter, the terminal fitting is inserted into the connector housing. Thus, the above-described wire harness is assembled.
[0005] 前述したワイヤハーネスの電線は、芯線の大きさと、被覆部の材質 (耐熱性の有無 などによる材質の変更）と、使用目的などを識別する必要がある。なお、使用目的と は、例えば、エアバック、 ABS (Antilock Brake System)や車速情報などの制御信号 や、動力伝達系統などの電線が用いられる自動車の系統 (システム）である。  [0005] The electric wire of the above-described wire harness needs to identify the size of the core wire, the material of the covering portion (change of material due to heat resistance, etc.), the purpose of use, and the like. The purpose of use is, for example, a control system such as an airbag, an ABS (Antilock Brake System) and vehicle speed information, and a vehicle system (system) using electric wires such as a power transmission system.
[0006] そこで、ワイヤハーネスに用いられる電線は、前述した切断、皮むきを行う各種のハ 一ネス製造装置 (例えば、特許文献 1参照。 )で、前述した使用目的（系統)を識別す るために外表面が所望の色に着色されてきた。前述した、特許文献 1に記載された ハーネス製造装置では、長手方向に沿って電線を移動させるとともに、一対のスタン プ間に電線を挟んで、電線を着色した後、一対の切断刃間に電線を挟んで、該電線 を所望の色に着色するとともに、所望の長さに切断してきた。 [0006] Therefore, the electric wire used for the wire harness is made of various types of cutting and peeling described above. The outer surface has been colored in a desired color to identify the above-mentioned purpose of use (system) in a one-ness manufacturing apparatus (for example, see Patent Document 1). In the harness manufacturing apparatus described in Patent Document 1 described above, the electric wire is moved along the longitudinal direction, the electric wire is sandwiched between a pair of stamps, and the electric wire is colored. The wire was colored in a desired color and cut to a desired length.

発明が解決しょうとする課題  Problems the invention is trying to solve
[0007] 前述した従来のハーネス製造装置は、一対のスタンプ間に電線を挟んで着色する ため、電線を着色する際に、該電線をー且停止する必要があった。このため、電線の 加工にかかる所要時間が長時間化して、作業効率が低下する傾向であった。  [0007] In the conventional harness manufacturing apparatus described above, since the electric wire is colored between a pair of stamps, it is necessary to stop the electric wire when coloring the electric wire. For this reason, the time required for processing the electric wire has been prolonged, and the working efficiency has tended to decrease.
[0008] また、前述した従来のハーネス製造装置は、一対のスタンプ間に電線を挟んで着 色するため、電線を連続して着色することができなレ、。例えば、前述した切断刃とスタ ンプとの間隔分、スタンプで着色してから電線を移動させて、切断すると、スタンプで 着色された箇所が電線の端末に位置する。このように、従来のハーネス製造装置で は、例えば、端末などの電線の一部分のみしか着色できなレ、。また、連続的に着色 するためには、電線の移動と停止を頻繁に繰り返す必要があって、作業効率が低下 するィ頃向であった。  [0008] Furthermore, in the above-described conventional harness manufacturing apparatus, since the electric wire is sandwiched between the pair of stamps and colored, the electric wire cannot be continuously colored. For example, if the electric wire is moved and cut after coloring with a stamp for the distance between the cutting blade and the stamp, the portion colored with the stamp is located at the end of the electric wire. Thus, in the conventional harness manufacturing apparatus, for example, only a part of the electric wire such as a terminal can be colored. In addition, in order to perform continuous coloring, it was necessary to frequently move and stop the electric wire, and work efficiency was likely to decrease.

Ejects (drips) toward the wire. In this way, the wire is colored during the relative movement between the wire and the coloring means. For this reason, since it is not necessary to stop the electric wires to color the electric wires, the working efficiency is not reduced.
[0022] また、電線と着色手段との相対的な移動中に電線に向かって一定量ずつ着色材を 噴出（滴射)するため、電線の任意の位置を着色でき、勿論連続的に電線を着色で きる。 [0022] In addition, since the coloring material is ejected (sprayed) by a fixed amount toward the electric wire at a time during relative movement between the electric wire and the coloring means, an arbitrary position of the electric wire can be colored.

[0023] なお、本明細書でレ、う着色材とは、色材（工業用有機物質）が水またはその他の溶 媒に溶解、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 力 Sある。より具体的な例として、本明細書でいう着色材とは、着色液と塗料との双方を 示している。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 しており、塗料とは、分散液中に顔料が分散しているものを示している。このため、着 色液で被覆部の外表面を着色すると、染料が被覆部内にしみ込み、塗料で被覆部 の外表面を着色すると、顔料が被覆部内にしみ込むことなく外表面に接着する。即ち 、本明細書でいう電線の外表面を着色するとは、電線の外表面の一部を染料で染め ることと、電線の外表面の一部に顔料を塗ることとを示している。 In this specification, the coloring material is a liquid material in which a coloring material (organic organic material) is dissolved or dispersed in water or another solvent. Organic materials include dyes and pigments (mostly organic and synthetic), and sometimes dyes are used as pigments and pigments are used as dyes. As a more specific example, the coloring material in this specification indicates both a coloring liquid and a paint. The term “colored liquid” refers to a substance in which a dye is dissolved or dispersed in a solvent, and the term “paint” refers to a substance in which a pigment is dispersed in a dispersion. Therefore, when the outer surface of the coated portion is colored with the coloring liquid, the dye penetrates into the coated portion, and when the outer surface of the coated portion is colored with the paint, the pigment adheres to the outer surface without penetrating into the coated portion. That is The term “coloring the outer surface of the electric wire” as used in the present specification means that a part of the outer surface of the electric wire is dyed with a dye and that a part of the outer surface of the electric wire is coated with a pigment.

In this case, the dye will surely penetrate into the coating, and the pigment will surely adhere to the outer surface of the coating.
[0025] 請求項 2に記載された本発明によれば、測定手段が電線の移動量を測定して、制 御手段が着色手段を電線の移動量に応じて制御する。このため、電線の移動速度が 速くなると着色材を噴出 (滴射)する時間間隔を短くし、電線の移動速度が遅くなると 着色材を噴出 (滴射)する時間間隔を長くすることができる。この場合、電線の移動速 度が変化しても、電線の外表面に付着した着色材の間隔を一定に保つことができる  According to the second aspect of the present invention, the measuring means measures the movement amount of the electric wire, and the control means controls the coloring means according to the movement amount of the electric wire. For this reason, when the moving speed of the electric wire increases, the time interval for ejecting (dropping) the coloring material can be shortened, and when the moving speed of the electric wire decreases, the time interval for ejecting (dropping) the coloring material can be lengthened. In this case, even if the moving speed of the electric wire changes, the distance between the coloring materials attached to the outer surface of the electric wire can be kept constant.
[0026] 請求項 3に記載された本発明によれば、移動手段としての引っ張り手段と、張力付 与手段との間に着色手段を設けている。また、張力付与手段が、引っ張り手段の逆 向きの摩擦力を電線に付与するので、確実に電線を張ることができる。このため、引 つ張り手段により引っ張れて、張力付与手段により張られた電線に向かって確実に着 色材を噴出（滴射)できる。 According to the third aspect of the present invention, the coloring means is provided between the pulling means as the moving means and the tension applying means. Further, since the tension applying means applies a friction force in the opposite direction of the pulling means to the electric wire, the electric wire can be securely tensioned. For this reason, the coloring material can be reliably ejected (drip sprayed) toward the electric wire stretched by the tension applying means by being pulled by the pulling means.
[0027] 請求項 4に記載された本発明によれば、弛み吸収手段が、電線に弛みが生じたとき にこの弛みを吸収する。このため、引っ張り手段により引っ張れて張力付与手段によ り張られた電線に向かって確実に着色材を噴出（滴射）できる。  [0027] According to the present invention described in claim 4, the slack absorbing means absorbs the slack when the slack occurs in the electric wire. For this reason, the coloring material can be reliably ejected (sprayed) toward the electric wire pulled by the pulling means and stretched by the tension applying means.
[0028] 請求項 5に記載された本発明によれば、弛み吸収手段が張力付与手段と着色手段 との間に設けられている。このため、着色手段の近傍では、電線を確実に張っておく こと力 Sできる。したがって、引っ張り手段により引っ張れて張力付与手段により張られ た電線に向かって確実に着色材を噴出（滴射)できる。  According to the present invention described in claim 5, the slack absorbing means is provided between the tension applying means and the coloring means. Therefore, in the vicinity of the coloring means, it is possible to ensure that the electric wire is stretched. Therefore, the coloring material can be reliably ejected (drip sprayed) toward the electric wire pulled by the pulling means and stretched by the tension applying means.
[0029] 請求項 6に記載された本発明によれば、張力付与手段が第 1の付勢力の摩擦力を 電線に付与し、弛み吸収手段が第 2の付勢力で電線を付勢する。このため、電線に 弛みがない状態では、弛み吸収手段が電線の移動を妨げることがなレ、。また、電線 に弛みが生じると、弛み吸収手段の第 2の付勢力により、電線が、長手方向に交差す る方向に沿って押されて、張られることとなる。 [0030] 請求項 7に記載された本発明によれば、弛み吸収手段が、一対の案内ローラと案 内ローラ間に設けられた移動ローラとを備えている。また、移動ローラが電線の長手 方向に交差する方向に沿って移動自在に設けられ、付勢手段により第 2の付勢力で 付勢されている。 According to the present invention described in claim 6, the tension applying means applies the frictional force of the first urging force to the electric wire, and the slack absorbing means urges the electric wire with the second urging force. For this reason, when there is no slack in the wire, the slack absorbing means does not hinder the movement of the wire. Further, when the slack occurs in the electric wire, the electric wire is pushed and stretched along the direction intersecting the longitudinal direction by the second biasing force of the slack absorbing means.

Therefore, the coloring material can be securely attached to any position of the electric wire. That is, it is possible to reliably color an arbitrary position of the electric wire.
[0032] 請求項 8に記載された本発明によれば、一対の案内ローラ間の中央に移動ローラ が設けられている。このため、移動ローラが移動する際に、移動ローラの上流側の電 線からの反力と、移動ローラの下流側の電線からの反力とが略等しくなる。このため、 移動ローラが、電線の長手方向に交差する方向に沿って素早く移動する。したがつ て、弛み吸収手段が、電線を常に張っておくことができる。  According to the present invention described in claim 8, the moving roller is provided at the center between the pair of guide rollers. For this reason, when the moving roller moves, the reaction force from the electric wire on the upstream side of the moving roller is substantially equal to the reaction force from the electric wire on the downstream side of the moving roller. For this reason, the moving roller moves quickly along the direction intersecting the longitudinal direction of the electric wire. Therefore, the slack absorbing means can keep the electric wire stretched at all times.
[0033] 請求項 9に記載された本発明によれば、移動ローラが一対の案内ローラ間の中央 より上流側に設けられている。このため、移動ローラより下流側の電線の曲がりが上 流側の電線の曲がりより緩やかになる。このため、着色手段に送り出される電線の曲 力 Sりを抑制できるとともに、電線の付与される張力を抑制できる。したがって、電線の 不意な破損を防止できる。  According to the ninth aspect of the present invention, the moving roller is provided upstream of the center between the pair of guide rollers. For this reason, the bending of the electric wire downstream of the moving roller becomes gentler than the bending of the electric wire upstream. For this reason, the bending force S of the electric wire sent out to the coloring means can be suppressed, and the tension applied to the electric wire can be suppressed. Therefore, unexpected breakage of the electric wire can be prevented.
[0034] 請求項 10に記載された本発明によれば、複数の着色手段は電線を中心とした周 方向に沿って並べられている。このため、確実に複数の着色材で電線の外表面を着 色できる。また、着色手段の電線の長手方向に沿った張力付与手段と引っ張り手段 との間隔を短くでき、電線の着色装置の小型化を図ることができる。  [0034] According to the present invention described in claim 10, the plurality of coloring means are arranged along the circumferential direction around the electric wire. Therefore, the outer surface of the electric wire can be reliably colored with a plurality of coloring materials. Further, the distance between the tension applying means and the pulling means along the longitudinal direction of the electric wire of the coloring means can be shortened, and the size of the electric wire coloring apparatus can be reduced.

For this reason, the electric wire can be colored in a desired color in the process of processing the electric wire. For this reason, there is no need to separately provide a processing step such as an electric wire cutting step independent of the electric wire coloring step.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0048] 以下、本発明の一実施形態にかかる電線の着色装置 (以下単に着色装置と呼ぶ） を図 1ないし図 6を参照して説明する。着色装置 1は、電線 3を所定の長さに切断して 、この電線 3の外表面 3aの一部に印 6を形成する装置である。即ち、着色装置 1は、 電線 3の外表面 3aを着色する即ちマーキング（Marking)する。  Hereinafter, an electric wire coloring apparatus according to an embodiment of the present invention (hereinafter, simply referred to as a coloring apparatus) will be described with reference to FIGS. 1 to 6. The coloring device 1 is a device that cuts the electric wire 3 into a predetermined length and forms a mark 6 on a part of the outer surface 3a of the electric wire 3. That is, the coloring device 1 colors or marks the outer surface 3a of the electric wire 3.
[0049] 電線 3は、移動体としての自動車などに配索されるワイヤハーネスを構成する。電 線 3は、図 6 (a)に示すように、導電性の芯線 4と、絶縁性の被覆部 5とを備えている。 芯線 4は、複数の素線が撚られて形成されている。芯線 4を構成する素線は、導電性 の金属からなる。また、芯線 4は、一本の素線から構成されても良い。被覆部 5は、例 えば、ポリ塩化ビュル（Polyvinylchloride： PVC)などの合成樹脂力、らなる。被覆部 5は 、芯線 4を被覆している。このため、電線 3の外表面 3aとは、被覆部 5の外表面をなし ている。  [0049] The electric wire 3 constitutes a wire harness that is routed to an automobile or the like as a moving body. As shown in FIG. 6 (a), the electric wire 3 includes a conductive core wire 4 and an insulating covering portion 5. The core wire 4 is formed by twisting a plurality of strands. The wires constituting the core wire 4 are made of a conductive metal. Further, the core wire 4 may be composed of one strand. The coating portion 5 is made of, for example, a synthetic resin such as polyvinyl chloride (PVC). The covering part 5 covers the core wire 4. Therefore, the outer surface 3a of the electric wire 3 forms the outer surface of the covering portion 5.
[0050] また、被覆部 5は、例えば白色などの単色 Pである。なお、被覆部 5を構成する合成 樹脂に所望の着色剤を混入して、電線 3の外表面 3aを単色 Pにしても良ぐ被覆部 5 を構成する合成樹脂に着色剤を混入することなぐ単色 Pを合成樹脂自体の色として 良い。被覆部 5を構成する合成樹脂に着色剤を混入せずに、単色 Pが合成樹脂自体 の色の場合、被覆部 5即ち電線 3の外表面 3aは、無着色であるという。このように、無 着色とは、被覆部 5を構成する合成樹脂に着色剤を混入せずに、電線 3の外表面 3a が合成樹脂自体の色であることを示してレ、る。  [0050] The covering portion 5 is, for example, a single color P such as white. In addition, a desired coloring agent is mixed into the synthetic resin forming the covering portion 5 so that the outer surface 3a of the electric wire 3 can be changed to a single color P without mixing a coloring agent into the synthetic resin forming the covering portion 5. Single color P is good as the color of the synthetic resin itself. When the single color P is the color of the synthetic resin itself without mixing a coloring agent into the synthetic resin constituting the coating portion 5, the coating portion 5, ie, the outer surface 3a of the electric wire 3, is said to be uncolored. As described above, “uncolored” indicates that the outer surface 3a of the electric wire 3 has the color of the synthetic resin itself without mixing a coloring agent into the synthetic resin constituting the covering portion 5.
[0051] 電線 3の外表面 3aには、複数の点 7を備えた印 6が形成されている。点 7は、色 B ( 図 6中に平行斜線で示す）である。色 Bは、単色 Pと異なる。点 7の平面形状は、図 6 ( b)に示すように、丸形である。点 7は、複数設けられており、予め定められるパターン にしたがって、電線 3の長手方向に沿って並べられている。図示例では、電線 3の長 手方向に沿って、点 7が等間隔に並べられている。また、互いに隣り合う点 7の中心 間の距離は、予め定められている。 [0051] A mark 6 having a plurality of points 7 is formed on the outer surface 3a of the electric wire 3. Point 7 is color B (indicated by the oblique lines in FIG. 6). Color B is different from single color P. The planar shape of the point 7 is a round shape as shown in FIG. Point 7 is provided in a plurality and has a predetermined pattern. , Are arranged along the longitudinal direction of the electric wires 3. In the illustrated example, points 7 are arranged at equal intervals along the longitudinal direction of the electric wire 3. Further, the distance between the centers of the points 7 adjacent to each other is predetermined.
[0052] 前述した構成の電線 3は、複数束ねられるとともに端部などにコネクタなどが取り付 けられて前述したワイヤハーネスを構成する。コネクタが自動車などの各種の電子機 器のコネクタにコネクタ結合して、ワイヤハーネス即ち電線 3は、各電子機器に各種 の信号や電力を伝える。 [0052] A plurality of the electric wires 3 having the above-described configuration are bundled and a connector or the like is attached to an end or the like to configure the above-described wire harness. The connector is connected to a connector of various electronic devices such as automobiles, and the wire harness, that is, the electric wire 3 transmits various signals and electric power to each electronic device.
[0053] また、前述した印 6の各点 7の色 Bが種々の色に変更されることにより、電線 3同士を 識別可能としている。図示例では、全ての点 7の色 Bを同じくしている力 必要に応じ て点 7毎に色 Bを変更して、点 7同士の色 Bを異ならせても良い。印 6の各点 7の色 B は、ワイヤハーネスの電線 3の線種、系統（システム）の識別などを行うために用いら れる。即ち、前述した印 6の各点 7の色 Bは、ワイヤハーネスの各電線 3の使用目的を 識別するために用いられる。  Further, by changing the color B of each point 7 of the mark 6 to various colors, the wires 3 can be distinguished from each other. In the illustrated example, the color B of all the points 7 is the same. The color B of the points 7 may be different by changing the color B for each point 7 as necessary. The color B at each point 7 of the mark 6 is used to identify the wire type and the system of the wire 3 of the wire harness. That is, the color B of each point 7 of the mark 6 is used to identify the purpose of use of each wire 3 of the wire harness.

[0055] フレーム 10は、工場などのフロア上などに設置される。フレーム 10は、水平方向に 伸びている。ガイドロール 11は、フレーム 10の一端部に回転自在に取り付けられて いる。ガイドロール 11は、長尺でかつ印 6が形成されていない電線束 50力 の電線 3 を矯正ユニット 13とに導くためのガイドである。ガイドロール 11は、矯正ユニット 13と 弛み吸収ユニット 14と着色ユニット 15とダクト 16とエンコーダ 17と切断機構 18とに順 に、電線 3を送り出す。  [0055] The frame 10 is installed on a floor such as a factory. The frame 10 extends horizontally. The guide roll 11 is rotatably attached to one end of the frame 10. The guide roll 11 is a guide for guiding the electric wire 3 having a long length and not having the mark 6 formed thereon and having a wire bundle of 50 force to the straightening unit 13. The guide roll 11 sends out the electric wire 3 in order to the straightening unit 13, the slack absorbing unit 14, the coloring unit 15, the duct 16, the encoder 17, and the cutting mechanism 18.
[0056] 送り出しローノレ 12は、フレーム 10の他端部に一対設けられている。これら一対の送 り出しロール 12は、フレーム 10に回転自在に支持されかつ鉛直方向に沿って並べら れている。送り出しローノレ 12は、図示しないモータなどにより、互いに逆方向に同回 転数で回転される。一対の送り出しロール 12は、互いの間に電線 3を挟み、かっこの 電線 3の長手方向に沿ってガイドロール 11から引っ張る。 [0056] A pair of the delivery lonerets 12 are provided at the other end of the frame 10. The pair of delivery rolls 12 are rotatably supported by the frame 10 and are arranged in the vertical direction. The delivery roller 12 is rotated at the same rotational speed in opposite directions by a motor (not shown) or the like. A pair of delivery rolls 12 sandwich the electric wire 3 between each other and The wire 3 is pulled from the guide roll 11 along the longitudinal direction.
[0057] 送り出しローノレ 12は、電線 3の長手方向に沿って該電線 3を引っ張って移動させる 引っ張り手段をなしている。このように、送り出しローノレ 12は、電線 3の長手方向に沿 つて該電線 3を移動させることで、電線 3の長手方向に沿って着色ユニット 15の後述 する着色ノズル 31と、電線 3とを相対的に移動させる。このため、電線 3は、ガイド口 ール 11から送り出しロール 12に向かって図 1中の矢印 Kに沿って移動する。矢印 K は、電線 3の移動方向をなしている。  [0057] The sending Lonole 12 serves as a pulling means for pulling and moving the electric wire 3 along the longitudinal direction of the electric wire 3. In this manner, the delivery Lohren 12 moves the electric wire 3 along the longitudinal direction of the electric wire 3 so that the colored nozzle 31 of the coloring unit 15 and the electric wire 3 can be relatively moved along the longitudinal direction of the electric wire 3. Move. For this reason, the electric wire 3 moves along the arrow K in FIG. Arrow K points in the direction of travel of wire 3.
[0058] 矯正ユニット 13は、ガイドロール 11の送り出しロール 12側に設けられており、ガイド ロール 11と送り出しロール 12との間に設けられている。即ち、矯正ユニット 13は、ガ イドロール 11より電線 3の移動方向 Kの下流側に設けられ、送り出しロール 12より電 線 3の移動方向 Kの上流側に設けられている。矯正ユニット 13は、板状のユニット本 体 20と、複数の第 1ローラ 21と、複数の第 2ローラ 22とを備えている。ユニット本体 20 は、フレーム 10に固定されている。  The correction unit 13 is provided on the side of the delivery roll 12 of the guide roll 11, and is provided between the guide roll 11 and the delivery roll 12. That is, the straightening unit 13 is provided downstream of the guide roll 11 in the moving direction K of the electric wire 3, and is provided upstream of the delivery roll 12 in the moving direction K of the electric wire 3. The correction unit 13 includes a plate-shaped unit body 20, a plurality of first rollers 21, and a plurality of second rollers 22. The unit body 20 is fixed to the frame 10.
[0059] 第 1及び第 2ローラ 21 , 22は、それぞれ、ユニット本体 20に回転自在に支持されて いる。複数の第 1ローラ 21は、水平方向（前述した移動方向 K)に沿って並べられ、 電線 3の上方に配されている。複数の第 2ローラ 22は、水平方向（前述した移動方向 K)に沿って並べられ、電線 3の下方に配されている。第 1ローラ 21と第 2ローラ 22と は、図 1に示すように、千鳥状に配されている。  [0059] The first and second rollers 21 and 22 are rotatably supported by the unit body 20, respectively. The plurality of first rollers 21 are arranged in a horizontal direction (the above-described movement direction K), and are arranged above the electric wire 3. The plurality of second rollers 22 are arranged in a horizontal direction (the above-described movement direction K), and are arranged below the electric wire 3.

[0063] 一対の案内ローラ 24は、案内ローラ支持フレーム 23に回転自在に支持されている 。案内ローラ 24は、電線 3の下方に配され、外周面に電線 3と接触することにより、移 動方向 Κから電線 3が脱落しないように、電線 3を案内する。このため、案内ローラ 24 は、電線 3の移動方向 Κを案内する。  [0063] The pair of guide rollers 24 is rotatably supported by the guide roller support frame 23. The guide roller 24 is disposed below the electric wire 3, and guides the electric wire 3 so that the electric wire 3 does not fall off from the moving direction に よ り by contacting the outer peripheral surface with the electric wire 3. For this reason, the guide roller 24 guides the moving direction の of the electric wire 3.

The air cylinder 27 is provided with a pressurized gas into the cylinder body 28 so that the telescopic rod 29, Is urged downward by a second urging force H2 (shown in FIGS. 1 and 2) in a direction orthogonal (intersecting) to the moving direction K. For this reason, the air cylinder 27 urges the moving roller 26 in the direction approaching the electric wire 3 with the second urging force # 2. The second bias Η2 is weaker than the first bias HI.

The main body 43, that is, the valve main body 41, is provided so as to be movable along the longitudinal direction of the cylindrical portion 45, that is, along the longitudinal direction of the nozzle body.
[0074] 弁体 44は、本体部 43の円板部 46に取り付けられている。即ち、弁体 44は、インサ 一ト部材 35内に収容されている。弁体 44は、噴出管 37の基端部 37aと相対する。弁 体 44は、噴出管 37の基端部 37aに接離する。なお、接離とは、近づいたり離れたり することである。弁体 44は、噴出管 37の基端部 37aに接触すると、この基端部 37aと の間を水密に保ち、流路 39内の着色材が噴出管 37内に侵入することを防止する。 また、弁体 44は、噴出管 37の基端部 37aから離れると、噴出管 37内を通って、着色 材が電線 3の外表面 3aに向かって噴出（滴射）されることを許容する。このように、弁 体 44は、図示しない開位置と、図 5中に実線で示す閉位置とに亘つて基端部 37aに 接離する。開位置では、弁体 44は、基端部 37aから離れて着色材を噴出管 37内を 通して電線 3に向かって滴射させる。閉位置では、弁体 44は、基端部 37aに接触し て着色材を噴出管 37内を通して電線 3に向かって滴射することを規制する。コィノレば ね 42は、円板部 46を弁体 44が噴出管 37の基端部 37aに近づく方向に付勢してい る。  [0074] The valve body 44 is attached to the disk portion 46 of the main body 43. That is, the valve body 44 is housed in the insert member 35. The valve body 44 faces the base end 37a of the ejection pipe 37. The valve body 44 comes into contact with and separates from the base end 37 a of the ejection pipe 37. Note that contact and separation refer to approaching and moving away. When the valve element 44 comes into contact with the base end 37a of the ejection pipe 37, it keeps the space between the valve end 44a and the base end 37a watertight, and prevents the coloring material in the flow path 39 from entering the ejection pipe 37. Further, when the valve element 44 is separated from the base end 37a of the ejection pipe 37, the coloring material is allowed to be ejected (drip) toward the outer surface 3a of the electric wire 3 through the ejection pipe 37. . In this way, the valve body 44 comes into contact with and separates from the base end portion 37a over the open position (not shown) and the closed position shown by the solid line in FIG. In the open position, the valve body 44 causes the coloring material to drop from the base end 37a through the ejection pipe 37 toward the electric wire 3. In the closed position, the valve element 44 contacts the base end 37a to restrict the colorant from being sprayed through the ejection pipe 37 toward the electric wire 3. The coil spring 42 urges the disc portion 46 in a direction in which the valve body 44 approaches the base end portion 37a of the ejection pipe 37.
[0075] 前述した構成の着色ノズル 31は、着色材供給源 32からの着色材を、流入管 36を 通して、流路 39内に導く。そして、コイル 40に印加されていない状態で、コイルばね 42の付勢力により、弁体 44が噴出管 37の基端部 37aに接触して、着色材が流路 39 内に位置付けられている。そして、着色ノズノレ 31は、コイル 40に印カロされると、コイル ばね 42の付勢力に抗して、円板部 46に取り付けられた弁体 44が噴出管 37の基端 部 37aから離れて、流路 39内の着色材を噴出管 37から噴出（滴射)する。また、コィ ノレ 40は、制御装置 19からの命令に基づいて、予め定められる一定時間印加される。 このため、着色ノズル 31は、一定量ずつ着色材を噴出（滴射)する。 The coloring nozzle 31 having the above-described configuration guides the coloring material from the coloring material supply source 32 into the flow channel 39 through the inflow pipe 36. Then, with no voltage applied to the coil 40, the coil spring Due to the urging force of 42, the valve body 44 comes into contact with the base end 37a of the ejection pipe 37, and the coloring material is positioned in the flow path 39. Then, when the colored noise 31 is applied to the coil 40, the valve element 44 attached to the disk part 46 separates from the base end 37a of the ejection pipe 37 against the urging force of the coil spring 42. Then, the coloring material in the flow path 39 is ejected (dropped) from the ejection pipe 37. The coil 40 is applied for a predetermined period of time based on a command from the control device 19. For this reason, the coloring nozzle 31 ejects (drops) the coloring material by a fixed amount.
[0076] また、着色ノズノレ 31は、ユニット本体 30に取り付けられると、電線 3の移動方向 に 沿って複数並べられるとともに、電線 3を中心とした周方向に沿って複数並べられて レ、る。図示例では、ユニット本体 30は、着色ノズノレ 31を電線 3の移動方向 Kに沿って 五つ並べている。ユニット本体 30は、電線 3を中心とした周方向に沿って着色ノズノレ 31を三つ並べている。 When attached to the unit body 30, a plurality of the colored knurls 31 are arranged along the moving direction of the electric wires 3, and are arranged in a plurality along the circumferential direction around the electric wires 3. In the illustrated example, the unit body 30 has five colored knurls 31 arranged along the moving direction K of the electric wire 3. The unit main body 30 has three colored knurls 31 arranged in the circumferential direction around the electric wire 3.
[0077] また、各着色ノズノレ 31は、図 4に示すように、噴出管 37の軸芯 R (図 4中に一点鎖 線で示す）の延長上に電線 3の最上部 3bが位置する状態で、ユニット本体 30に支持 される。なお、着色ノズノレ 31は、軸芯 Rに沿って着色材を噴出（滴射）する。このため 、着色ノズノレ 31は、電線 3の最上部 3bに向かって着色材を一定量ずつ噴出（滴射） する。また、前述した構成の着色ノズル 31は、本明細書に記した着色手段をなしてい る。  [0077] Further, as shown in Fig. 4, each colored nozzle 31 is in a state in which the uppermost portion 3b of the electric wire 3 is located on the extension of the axis R of the ejection pipe 37 (shown by a dashed line in Fig. 4). And is supported by the unit body 30. In addition, the coloring nozzle 31 ejects (drops) a coloring material along the axis R. For this reason, the colored lipstick 31 jets (drops) a coloring material by a fixed amount toward the uppermost portion 3 b of the electric wire 3. Further, the coloring nozzle 31 having the above-described configuration constitutes the coloring means described in this specification.
[0078] 着色材供給源 32は、着色材を収容するとともに、着色ノズノレ 31の流入管 36内に着 色材を供給する。着色材供給源 32は、各着色ノズノレ 31に一つ対応している。着色 材供給源 32が、着色ノズル 31に供給する着色材の色 Bは、互いに異なっていても良 ぐ互いに同じであっても良い。  The coloring material supply source 32 accommodates the coloring material and supplies the coloring material into the inflow pipe 36 of the colored nozzle 31. One coloring material supply source 32 corresponds to each colored lipstick 31. The color B of the coloring material supplied from the coloring material supply source 32 to the coloring nozzle 31 may be different from each other or may be the same as each other.
[0079] 加圧気体供給源 33は、加圧された気体を着色材供給源 32内に供給する。加圧気 体供給源 33は、加圧された気体を着色材供給源 32内に供給することで、着色ノズ ル 31の弁体 44が噴出管 37の基端部 37aから離れると、流路 39内の着色材が速や 力、に噴出管 37から噴出（滴射)するようにする。  [0079] The pressurized gas supply source 33 supplies the pressurized gas into the colorant supply source 32. The pressurized gas supply source 33 supplies the pressurized gas into the colorant supply source 32 so that when the valve body 44 of the coloring nozzle 31 separates from the base end 37a of the ejection pipe 37, the flow path 39 The colorant inside is ejected (drip) from the ejection pipe 37 at high speed and force.
[0080] 前述した構成の着色ユニット 15は、制御装置 19からの命令に基づいて、任意の着 色ノズノレ 31のコイル 40に印加されて弁体 44が噴出管 37の基端部 37aから離れる。 そして、着色ユニット 15は、任意の着色ノズノレ 31の流路 39内の着色材を一定量ず つ電線 3に向かって噴出（滴射)する。 In the coloring unit 15 having the above-described configuration, the valve element 44 is applied to the coil 40 of an arbitrary coloring nozzle 31 based on a command from the control device 19, and the valve body 44 is separated from the base end 37a of the ejection pipe 37. Then, the coloring unit 15 removes a certain amount of the coloring material in the flow path 39 of the arbitrary coloring nozzle 31. And squirt (drip) toward the electric wire 3.
[0081] 前述した着色材とは、本明細書に記した着色材をなしており、色材（工業用有機物 質)が水またはその他の溶媒に溶解、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がある。より具体的な例として、着色材とは、着色液また は塗料である。 [0081] The coloring material described above is a coloring material described in this specification, and is a liquid substance in which a coloring material (an industrial organic material) is dissolved and dispersed in water or another solvent. Organic substances include dyes and pigments (mostly organic substances, 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 paint.
[0082] 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しており、 塗料とは、分散液中に顔料が分散しているものを示している。このため、着色液が電 線 3の外表面 3aに付着すると、染料が被覆部 5内にしみ込み、塗料が電線 3の外表 面 3aに付着すると、顔料が被覆部 5内にしみ込むことなく外表面 3aに接着する。即 ち、着色ユニット 15は、電線 3の外表面 3aの一部を染料で染める又は電線 3の外表 面 3aに顔料を塗る。このため、電線 3の外表面 3aを着色するとは、電線 3の外表面 3 aの一部を染料で染める（染色する）ことと、電線 3の外表面 3aの一部に顔料を塗るこ ととを示している。  [0082] The term "colored liquid" refers to a substance in which a dye is dissolved or dispersed in a solvent, and the term "paint" refers to a substance in which a pigment is dispersed in a dispersion. For this reason, when the coloring liquid adheres to the outer surface 3a of the electric wire 3, the dye penetrates into the coating portion 5, and when the paint adheres to the outer surface 3a of the electric wire 3, the pigment does not permeate into the coating portion 5 without penetrating. Glue to surface 3a. That is, the coloring unit 15 dyes a part of the outer surface 3a of the electric wire 3 with a dye or paints the outer surface 3a of the electric wire 3 with a pigment. For this reason, coloring the outer surface 3a of the electric wire 3 means that a part of the outer surface 3a of the electric wire 3 is dyed (dyed) and that a part of the outer surface 3a of the electric wire 3 is painted with a pigment. Are shown.
[0083] また、前記溶媒と分散液は、被覆部 5を構成する合成樹脂と親和性のあるものが望 ましレ、。この場合、染料が被覆部 5内に確実にしみ込んだり、顔料が外表面 3aに確 実に接着することとなる。さらに、滴射とは、着色ノズル 31から液状の着色材が、液滴 の状態即ち滴の状態で、電線 3の外表面 3aに向かって一定量ずつ則ち一滴ずつ付 勢されて打ち出されることを示している。このため、本実施形態の着色装置 1の着色ノ ズノレ 31は、着色材を、液滴の状態即ち滴の状態で、電線 3の外表面 3aに向かって 付勢して打ち出す。  [0083] Further, it is desirable that the solvent and the dispersion have an affinity for the synthetic resin constituting the coating portion 5. In this case, the dye will surely penetrate into the coating portion 5, and the pigment will surely adhere to the outer surface 3a. Further, the term “droplet spraying” means that a liquid colorant is ejected from the coloring nozzle 31 in a state of liquid droplets, that is, in a state of droplets, by being urged toward the outer surface 3a of the electric wire 3 by a predetermined amount, that is, one by one. Is shown. For this reason, the coloring nozzle 31 of the coloring device 1 of the present embodiment urges the coloring material toward the outer surface 3a of the electric wire 3 in a droplet state, that is, in a droplet state.
[0084] ダクト 16は、着色ユニット 15の送り出しロール 12側に設けられており、着色ユニット 15と送り出しロール 12との間に設けられている。即ち、ダクト 16は、着色ユニット 15よ り電線 3の移動方向 Kの下流側に設けられ、送り出しロール 12より電線 3の移動方向 Kの上流側に設けられている。ダクト 16は、筒状に形成されており、内側に電線 3を 通す。ダクト 16には、真空ポンプなどの図示しない吸引手段が連結している。吸引手 段は、ダ外 16内の気体を吸引して、着色材中の溶媒と分散液などが着色装置 1外 に充満することを防止する。 [0085] エンコーダ 17は、送り出しロール 12より電線 3の移動方向 Kの下流側に設けられて いる。エンコーダ 17は、図 1に示すように、回転子 47を一対備えている。回転子 47は 、軸芯周りに回転可能に支持されている。回転子 47の外周面は、一対の送り出し口 ール 12間に挟まれた電線 3の外表面 3aと接触している。回転子 47は、矢印 Kに沿つ て、芯線 4即ち電線 3が走行 (移動）すると、回転する。即ち、回転子 47は、矢印 Kに 沿った芯線 4即ち電線 3の走行 (移動）とともに、軸芯周りに回転する。勿論、矢印 に沿った芯線 4即ち電線 3の走行 (移動）量と、回転子 47の回転数とは比例する。 The duct 16 is provided on the delivery roll 12 side of the coloring unit 15, and is provided between the coloring unit 15 and the delivery roll 12. That is, the duct 16 is provided downstream of the coloring unit 15 in the moving direction K of the electric wire 3, and is provided upstream of the delivery roll 12 in the moving direction K of the electric wire 3. The duct 16 is formed in a tubular shape, and passes the electric wire 3 inside. A suction means (not shown) such as a vacuum pump is connected to the duct 16. The suction means sucks the gas in the outside 16 to prevent the solvent and the dispersion in the coloring material from filling the outside of the coloring apparatus 1. [0085] The encoder 17 is provided downstream of the feed roll 12 in the moving direction K of the electric wire 3. The encoder 17 includes a pair of rotors 47, as shown in FIG. The rotor 47 is supported rotatably around the axis. The outer peripheral surface of the rotor 47 is in contact with the outer surface 3a of the electric wire 3 sandwiched between the pair of delivery ports 12. The rotor 47 rotates when the core wire 4, that is, the electric wire 3 travels (moves) along the arrow K. That is, the rotor 47 rotates around the axis along with the movement (movement) of the core wire 4, that is, the electric wire 3 along the arrow K. Of course, the traveling (moving) amount of the core wire 4, that is, the electric wire 3 along the arrow is proportional to the rotation speed of the rotor 47.
[0086] エンコーダ 17は、制御装置 19に接続している。エンコーダ 17は、回転子 47が所定 角度ずつ回転すると、制御装置 19に向かってパルス状の信号を出力する。即ち、ェ ンコーダ 17は、矢印 Kに沿った電線 3の移動量に応じた情報を、制御装置 19に向か つて出力する。このように、エンコーダ 17は、電線 3の移動量に応じた情報を測定し て、電線 3の移動量に応じた情報を制御装置 19に向かって出力する。通常ェンコ一 ダ 17では電線 3と回転子 47の摩擦で電線 3の移動量に応じたパルス信号が出力さ れる。しかし、電線 3の外表面 3aの状態により移動量とパルス数が必ずしも一致しな い場合は、別の場所で速度情報を入手し、その情報をフィードバックし、比較演算し ても良い。  [0086] The encoder 17 is connected to the control device 19. The encoder 17 outputs a pulse signal to the control device 19 when the rotor 47 rotates by a predetermined angle. That is, the encoder 17 outputs information corresponding to the moving amount of the electric wire 3 along the arrow K to the control device 19. Thus, the encoder 17 measures information according to the movement amount of the electric wire 3 and outputs information corresponding to the movement amount of the electric wire 3 to the control device 19. Normally, the encoder 17 outputs a pulse signal corresponding to the amount of movement of the electric wire 3 due to friction between the electric wire 3 and the rotor 47. However, when the movement amount and the pulse number do not always match depending on the state of the outer surface 3a of the electric wire 3, the speed information may be obtained in another place, the information may be fed back, and the comparison operation may be performed.
[0087] 切断機構 18は、エンコーダ 17の一対の回転子 47より電線 3の移動方向 Kの下流 側に配されている。切断機構 18は、一対の切断刃 48, 49を備えている。一対の切 断刃 48, 49は、鉛直方向に沿って並べられている。一対の切断刃 48, 49は、鉛直 方向に沿って互いに近づいたり離れたりする。一対の切断刃 48, 49は、互いに近づ くと、一対の送り出しロール 12によって送り出された電線 3を互いの間に挟んで、切 断する。一対の切断刃 48, 49は、互いに離れると、勿論、前記電線 3から離れる。  [0087] The cutting mechanism 18 is disposed downstream of the pair of rotors 47 of the encoder 17 in the moving direction K of the electric wire 3. The cutting mechanism 18 includes a pair of cutting blades 48, 49. The pair of cutting blades 48, 49 are arranged along the vertical direction. The pair of cutting blades 48, 49 approach and move away from each other along the vertical direction. When the pair of cutting blades 48 and 49 approach each other, the pair of cutting blades 48 and 49 sandwich the electric wire 3 fed by the pair of feed rolls 12 therebetween to cut the electric wire 3. When the pair of cutting blades 48 and 49 are separated from each other, they are, of course, separated from the electric wire 3.
[0088] 制御装置 19は、周知の RAM、 ROM, CPUなどを備えたコンピュータである。制御 装置 19は、送り出しローノレ 12と、エンコーダ 17と、切断機構 18と、着色ノズル 31など と接続しており、これらの動作を制御することにより、着色装置 1全体の制御をつかさ どる。  The control device 19 is a computer including a well-known RAM, ROM, CPU, and the like. The control device 19 is connected to the delivery roller 12, the encoder 17, the cutting mechanism 18, the coloring nozzle 31, and the like, and controls the operation of the coloring device 1 as a whole by controlling these operations.
[0089] 制御装置 19は、予め印 6のパターンを記憶している。制御装置 19は、エンコーダ 1 7から所定のパルス状の信号即ち電線 3の移動量に応じた情報が入力すると、予め 定められた着色ノズル 31のコイル 40に一定時間印加して、該着色ノズル 31から電 線 3に向かって着色材を一定量ずつ噴出（滴射）させる。制御装置 19は、予め記憶し た印 6のパターンにしたがって、電線 3の移動速度が速くなると着色ノズル 31から着 色材を噴出 (滴射)する時間間隔を短くし、電線 3の移動速度が遅くなると着色ノズノレ 31から着色材を噴出 (滴射)する時間間隔を長くする。こうして、制御装置 19は、予 め記憶したパターンにしたがって、電線 3を着色する。制御装置 19は、エンコーダ 17 が測定した電線 3の移動量に基づいて、着色ノズル 31に着色材を一定量ずつ噴出（ 滴射）させる。 The control device 19 stores the pattern of the mark 6 in advance. When a predetermined pulse signal, that is, information corresponding to the amount of movement of the electric wire 3 is input from the encoder 17, the control device 19 The coloring material 31 is applied to a predetermined coil 40 of the coloring nozzle 31 for a certain period of time, and the coloring material is ejected (droplets) from the coloring nozzle 31 toward the electric wire 3 by a constant amount. When the moving speed of the electric wire 3 increases according to the pattern of the mark 6 stored in advance, the control device 19 shortens the time interval for ejecting (dropping) the coloring material from the coloring nozzle 31 so that the moving speed of the electric wire 3 is reduced. When the time is late, the time interval for jetting (dropping) the coloring material from the colored sponge 31 is increased. Thus, the control device 19 colors the electric wire 3 according to the previously stored pattern. The control device 19 causes the coloring nozzle 31 to jet (drip) the coloring material by a predetermined amount based on the movement amount of the electric wire 3 measured by the encoder 17.
[0090] また、制御装置 19は、エンコーダ 17からの情報により、電線 3が所定量移動したと 判定すると、送り出しロール 12を停止した後、一対の切断刃 48， 49を互いに近づけ て電線 3を切断する。  Further, when the control device 19 determines from the information from the encoder 17 that the electric wire 3 has moved by a predetermined amount, the control device 19 stops the delivery roll 12 and then brings the pair of cutting blades 48 and 49 closer to each other to connect the electric wire 3. Disconnect.
[0091] 前述した構成の着色装置 1で、電線 3の外表面 3aに印 6を形成する即ち電線 3の外 表面 3aを着色する際には、まず、ガイドロール 11をフレーム 10に取り付ける。一対の 切断刃 48, 49を互いに離しておき、電線束 50力 の電線 3をガイドロール 11を介し て矯正ユニット 13と弛み吸収ユニット 14と着色ユニット 15とダクト 16とに順に通して、 一対の送り出しロール 12間に挟む。そして、着色ユニット 15のユニット本体 30の所 定箇所に着色ノズル 31を取り付け、各着色ノズル 31に着色材供給源 32を連結する 。さらに、加圧気体供給源 33を着色材供給源 32に連結し、吸引手段でダクト 16内の 気体を吸引する。  [0091] When forming the mark 6 on the outer surface 3a of the electric wire 3 with the coloring device 1 having the above-described configuration, that is, when coloring the outer surface 3a of the electric wire 3, first, the guide roll 11 is attached to the frame 10. The pair of cutting blades 48 and 49 are separated from each other, and the electric wire 3 having a bundle of 50 forces is passed through the straightening unit 13, the slack absorbing unit 14, the coloring unit 15, and the duct 16 via the guide roll 11 in order, and It is sandwiched between the delivery rolls 12. Then, a coloring nozzle 31 is attached to a predetermined position of the unit main body 30 of the coloring unit 15, and a coloring material supply source 32 is connected to each coloring nozzle 31. Further, the pressurized gas supply source 33 is connected to the coloring material supply source 32, and the gas in the duct 16 is sucked by the suction means.
[0092] そして、送り出しロール 12を回転駆動して、電線 3をガイドロール 11力 引っ張って 、該電線 3の長手方向に沿って移動させるとともに、矯正ユニット 13により電線 3に第 1の付勢力 HIの摩擦力を付与して、該電線 3を張っておく。そして、エアシリンダ 27 で移動ローラ 26即ち電線 3を第 2の付勢力 H2で付勢しておく。  [0092] Then, the delivery roll 12 is rotationally driven to pull the electric wire 3 by the force of the guide roll 11 to move the electric wire 3 along the longitudinal direction of the electric wire 3, and the first urging force HI is applied to the electric wire 3 by the straightening unit 13. The electric wire 3 is stretched by applying a frictional force of Then, the moving roller 26, that is, the electric wire 3 is urged by the air cylinder 27 with the second urging force H2.
[0093] そして、エンコーダ 17から所定の順番のパルス状の信号が制御装置 19に入力する と、制御装置 19は、予め定められた着色ノズノレ 31のコイル 40に一定時間、所定間 隔毎に印加する。すると、着色ノズノレ 31は、着色材を一定量ずつ電線 3の外表面 3a に向かって噴出（滴射)する。  [0093] When a pulse signal in a predetermined order is input from the encoder 17 to the control device 19, the control device 19 applies the signal to the coil 40 of the predetermined colored noise 31 for a predetermined time at predetermined intervals. I do. Then, the colored lipstick 31 jets (drips) the coloring material by a fixed amount toward the outer surface 3 a of the electric wire 3.
[0094] そして、電線 3の外表面 3aに付着した着色材から前述した溶媒または分散液が蒸 発して、電線 3の外表面 3aを染料で染める又は外表面 3aに顔料を塗る。電線 3の外 表面 3aに付着した着色材力 蒸発した溶媒または分散液は、ダクト 16内から吸引手 段に吸引される。こうして、電線 1の外表面 3aが着色される。 [0094] Then, the above-described solvent or dispersion is vaporized from the coloring material attached to the outer surface 3a of the electric wire 3. Then, the outer surface 3a of the electric wire 3 is dyed with a dye or the outer surface 3a is coated with a pigment. Colorant Attached to Outer Surface 3a of Electric Wire 3 Evaporated solvent or dispersion is sucked from duct 16 by a suction means. Thus, the outer surface 3a of the electric wire 1 is colored.
[0095] エンコーダ 17などからの情報により、制御装置 19が所定の長さの電線 3を送り出し たと判定すると、この制御装置 19は、送り出しロール 12を停止する。すると、特に、弛 み吸収ユニット 14の一対の案内ローラ 24間で電線 3が弛んで、第 2の付勢力 H2で 付勢された移動ローラ 26が図 1及び図 2中に二点鎖線で示す位置に変位する。する と、弛み吸収ユニット 14のエアシリンダ 27の伸縮ロッド 29が伸長する。そして、弛み 吸収ユニット 14は、電線 3の弛みを吸収する。  [0095] When it is determined from the information from the encoder 17 or the like that the control device 19 has sent out the electric wire 3 having a predetermined length, the control device 19 stops the sending-out roll 12. Then, in particular, the electric wire 3 is loosened between the pair of guide rollers 24 of the slack absorbing unit 14, and the moving roller 26 urged by the second urging force H2 is shown by a two-dot chain line in FIGS. 1 and 2. Displace to position. Then, the telescopic rod 29 of the air cylinder 27 of the slack absorbing unit 14 extends. Then, the slack absorbing unit 14 absorbs the slack of the electric wire 3.
[0096] そして、一対の切断刃 48, 49が互いに近づいて、これら切断刃 48, 49間に電線 3 を挟んで切断する。こうして、図 6などに示された外表面 3aに印 6が形成された電線 3 が得られる。  [0096] Then, the pair of cutting blades 48, 49 approach each other, and cut the electric wire 3 between the cutting blades 48, 49. Thus, the electric wire 3 having the mark 6 formed on the outer surface 3a shown in FIG. 6 and the like is obtained.
[0097] 本実施形態によれば、電線 3の長手方向に沿って、電線 3と着色ノズル 31とを相対 的に移動させている間に、着色ノズノレ 31がー定量ずつ着色材を電線 3に向かって噴 出（滴射）する。このように、電線 3と着色ノズル 31との相対的な移動中に、電線 3を 着色する。このため、電線 3を着色するために、電線 3を停止する必要がないので、 作業効率を低下させることがない。また、電線 3と着色ノズル 31との相対的な移動中 に電線 3に向かって一定量ずつ着色材を噴出（滴射)するため、電線 3の任意の位置 を着色でき、勿論連続的に電線 3を着色できる。  [0097] According to the present embodiment, while the wire 3 and the coloring nozzle 31 are relatively moved along the longitudinal direction of the wire 3, the colored material 31 applies the coloring material to the wire 3 by a fixed amount. It gushes (drops) toward it. Thus, the electric wire 3 is colored during the relative movement between the electric wire 3 and the coloring nozzle 31. For this reason, since it is not necessary to stop the electric wire 3 in order to color the electric wire 3, the working efficiency is not reduced. In addition, since a certain amount of the coloring material is ejected (drip) toward the electric wire 3 while the electric wire 3 and the coloring nozzle 31 are moving relative to each other, an arbitrary position of the electric wire 3 can be colored. 3 can be colored.
[0098] エンコーダ 17が電線 3の移動量を測定して、制御装置 19が着色ノズノレ 31を電線 3 の移動量に応じて制御する。このため、電線 3の移動速度が速くなると着色材を噴出 (滴射)する間隔を短くし、電線 3の移動速度が遅くなると着色材を噴出 (滴射)する間 隔を長くすることができる。このように、電線 3の移動速度が変化しても、電線 3の外表 面 3aに付着した着色材の間隔を一定に保つことができる。  [0098] The encoder 17 measures the amount of movement of the electric wire 3, and the control device 19 controls the colored nozzle 31 according to the amount of movement of the electric wire 3. For this reason, when the moving speed of the electric wire 3 increases, the interval at which the coloring material is ejected (drip) can be shortened, and when the moving speed of the electric wire 3 decreases, the interval at which the coloring material is ejected (drip) can be increased. . Thus, even if the moving speed of the electric wire 3 changes, the interval between the coloring materials attached to the outer surface 3a of the electric wire 3 can be kept constant.
[0099] したがって、電線 3の移動速度が変化しても、予め定められるパターンにしたがって 電線 3の外表面 3aに着色材を付着させることができる。即ち、電線 3の移動速度が変 ィ匕しても、予め定められるパターンにしたがって、電線 3を着色できる。  [0099] Therefore, even if the moving speed of the electric wire 3 changes, the coloring material can be attached to the outer surface 3a of the electric wire 3 according to a predetermined pattern. That is, even if the moving speed of the electric wire 3 changes, the electric wire 3 can be colored according to a predetermined pattern.
[0100] 送り出しローノレ 12と、矯正ユニット 13との間に着色ノズル 31を設けている。また、矯 正ユニット 13が、送り出しロール 12の逆向きの摩擦力を電線 3に付与するので、確実 に電線 3を張ることができる。このため、送り出しロール 12により引っ張れて、矯正ュ ニット 13により張られた電線 3に噴出（滴射）した着色材を確実に付着させることがで きる。したがって、電線 3の任意の位置を確実に着色でき、予め定められるパターン にしたがって、電線 3を確実に着色できる。 [0100] A coloring nozzle 31 is provided between the delivery roller 12 and the correction unit 13. In addition, The forward unit 13 applies the frictional force of the delivery roll 12 in the opposite direction to the electric wire 3, so that the electric wire 3 can be securely stretched. For this reason, the coloring material ejected (drip sprayed) can be reliably attached to the electric wire 3 pulled by the delivery roll 12 and stretched by the straightening unit 13. Therefore, an arbitrary position of the electric wire 3 can be reliably colored, and the electric wire 3 can be reliably colored according to a predetermined pattern.
[0101] 弛み吸収ユニット 14が、電線 3に弛みが生じたときにこの弛みを吸収する。このため 、送り出しロール 12により引っ張れて、矯正ユニット 13により張られた電線 3が位置ず れすることを防止できる。したがって、張られた電線 3に向かって着色材を噴出（滴射 )するので、電線 3の任意の位置に確実に着色材を付着できる。したがって、電線 3の 任意の位置を確実に着色でき、予め定められるパターンにしたがって、電線 3を確実 に着色できる。 [0101] The slack absorbing unit 14 absorbs the slack when the wire 3 becomes slack. Therefore, it is possible to prevent the electric wire 3 stretched by the straightening unit 13 from being displaced by being pulled by the delivery roll 12. Therefore, the coloring material is ejected (dropped) toward the stretched electric wire 3, so that the coloring material can be securely attached to an arbitrary position of the electric wire 3. Therefore, an arbitrary position of the electric wire 3 can be reliably colored, and the electric wire 3 can be reliably colored according to a predetermined pattern.
[0102] 弛み吸収ユニット 14が、矯正ユニット 13と着色ノズノレ 31との間に設けられている。  [0102] The slack absorbing unit 14 is provided between the straightening unit 13 and the colored lipstick 31.
このため、着色ノズノレ 31の近傍では、電線 3を確実に張っておくことができる。したが つて、着色ノズノレ 31の近傍で、電線 3が位置ずれすることを防止できる。このため、矯 正ユニット 13により張られた電線 3に噴出（滴射）した着色材をより確実に付着させる こと力 Sできる。したがって、電線 3の任意の位置をより確実に着色でき、予め定められ るパターンにしたがって、電線 3をより確実に着色できる。  For this reason, the electric wire 3 can be securely stretched in the vicinity of the colored lipstick 31. Accordingly, it is possible to prevent the electric wire 3 from being displaced in the vicinity of the colored knurling 31. For this reason, it is possible to more securely attach the coloring material ejected (dropped) to the electric wire 3 stretched by the correction unit 13. Therefore, an arbitrary position of the electric wire 3 can be more reliably colored, and the electric wire 3 can be more reliably colored according to a predetermined pattern.
[0103] 矯正ユニット 13が第 1の付勢力 H2の摩擦力を電線 3に付与し、弛み吸収ユニット 1 4が第 2の付勢力 H2で電線 3を付勢する。このため、電線 3に弛みがない状態では、 弛み吸収ユニット 14が電線 3を不用意に変位させることなぐ該電線 3の移動を妨げ ない。  [0103] The straightening unit 13 applies the frictional force of the first urging force H2 to the electric wire 3, and the slack absorbing unit 14 urges the electric wire 3 with the second urging force H2. Therefore, in a state where the electric wire 3 is not slack, the movement of the electric wire 3 is not prevented without the slack absorbing unit 14 displacing the electric wire 3 carelessly.
[0104] また、電線 3に弛みが生じると、弛み吸収ユニット 14の第 2の付勢力 H2により、電 線 3が、その長手方向に交差する方向に沿って押されて、張られることとなる。このた め、電線 3を常に張っておくことができるので、電線 3の位置ずれを防止できる。この ため、矯正ユニット 13により張られた電線 3に噴出（滴射）した着色材をより確実に付 着させることができる。したがって、電線 3の任意の位置をより確実に着色でき、予め 定められるパターンにしたがって、電線 3をより確実に着色できる。  When the electric wire 3 becomes slack, the electric wire 3 is pushed and stretched by the second urging force H2 of the slack absorbing unit 14 along a direction intersecting the longitudinal direction thereof. . For this reason, since the electric wire 3 can always be stretched, displacement of the electric wire 3 can be prevented. For this reason, the coloring material ejected (drip) onto the electric wire 3 stretched by the straightening unit 13 can be more reliably adhered. Therefore, an arbitrary position of the electric wire 3 can be more reliably colored, and the electric wire 3 can be more reliably colored according to a predetermined pattern.
[0105] 弛み吸収ユニット 14が、一対の案内ローラ 24と案内ローラ 24間に設けられた移動 ローラ 26とを備えている。また、移動ローラ 26が電線 3の長手方向に交差する方向に 沿って移動自在に設けられ、エアシリンダ 27により第 2の付勢力 H2で付勢されてい る。 [0105] The slack absorbing unit 14 is provided between the pair of guide rollers 24 and the guide rollers 24. And a roller 26. Further, a moving roller 26 is provided movably along a direction intersecting the longitudinal direction of the electric wire 3 and is urged by an air cylinder 27 with a second urging force H2.
[0106] このため、弛み吸収ユニット 14が、電線 3を第 2の付勢力 H2で付勢して、該電線 3 を常に張っておくことができ、電線 3の位置ずれを防止できる。このため、矯正ュニッ ト 13により張られた電線 3に噴出（滴射）した着色材をより確実に付着させることがで きる。したがって、電線 3の任意の位置をより確実に着色でき、予め定められるパター ンにしたがって、電線 3をより確実に着色できる。  [0106] For this reason, the slack absorbing unit 14 urges the electric wire 3 with the second urging force H2, so that the electric wire 3 can always be stretched, and the displacement of the electric wire 3 can be prevented. For this reason, the coloring material that has been jetted (dropped) onto the electric wire 3 stretched by the straightening unit 13 can be more reliably adhered. Therefore, an arbitrary position of the electric wire 3 can be more reliably colored, and the electric wire 3 can be more reliably colored according to a predetermined pattern.
[0107] 一対の案内ローラ 24間の中央に移動ローラ 26が設けられている。このため、移動 ローラ 26が移動する際に、移動方向 Kの上流側の電線 3からの移動ローラ 26に対す る反力と、移動方向 Kの下流側の電線 3からの移動ローラ 26に対する反力とが略等 しくなる。このため、移動ローラ 26が、電線 3の長手方向に交差する方向に沿って素 早く移動する。したがって、弛み吸収ユニット 14が、電線 3を常に張っておくことがで きる。したがって、電線 3の任意の位置をより確実に着色でき、予め定められるパター ンにしたがって、電線 3をより確実に着色できる。  [0107] A moving roller 26 is provided at the center between the pair of guide rollers 24. Therefore, when the moving roller 26 moves, the reaction force against the moving roller 26 from the electric wire 3 on the upstream side in the moving direction K and the reaction force on the moving roller 26 from the electric wire 3 on the downstream side in the moving direction K. Are almost equal. Therefore, the moving roller 26 moves quickly along the direction intersecting the longitudinal direction of the electric wire 3. Therefore, the slack absorbing unit 14 can always stretch the electric wire 3. Therefore, an arbitrary position of the electric wire 3 can be more reliably colored, and the electric wire 3 can be more reliably colored according to a predetermined pattern.
[0108] 電線 3を中心とした周方向に沿って複数の着色ノズノレ 31を並べられている。このた め、確実に複数の着色材で電線 3の外表面 3aを着色できる。また、電線 3の移動方 向 Kに沿った矯正ユニット 13と送り出しロール 12との間隔を短くでき、着色装置 1の 小型化を図ることができる。  [0108] A plurality of colored knurls 31 are arranged along the circumferential direction around the electric wire 3. Therefore, the outer surface 3a of the electric wire 3 can be reliably colored with a plurality of coloring materials. Further, the distance between the straightening unit 13 and the delivery roll 12 along the moving direction K of the electric wire 3 can be shortened, and the size of the coloring apparatus 1 can be reduced.
[0109] 電線 3を加工する加工手段としての切断機構 18を備えている。このため、電線 3を 切断 (加工）する工程で、該電線 3を所望の色に着色できる。このため、電線着色ェ 程と独立した電線切断工程などの加工工程を別途設ける必要がなレ、。したがって、 電線 3の加工工程即ちワイヤハーネスなどの電線 3を用いた製品の組立に力、かるェ 程が増加することを防止できる。  [0109] A cutting mechanism 18 as a processing means for processing the electric wire 3 is provided. Therefore, the wire 3 can be colored in a desired color in the step of cutting (working) the wire 3. Therefore, it is not necessary to provide a separate processing step such as a wire cutting step independent of the wire coloring step. Therefore, it is possible to prevent an increase in the strength of the wire 3 in the process of processing the wire 3, that is, in assembling a product using the wire 3 such as a wire harness.
[0110] 前述した実施形態では、電線 3を移動させて、着色ユニット 15の各着色ノズノレ 31と 電線 3とを相対的に移動させている。し力 ながら、本発明では、着色ユニット 15の各 着色ノズノレ 31を移動させても良ぐ電線 3と着色ユニット 15の各着色ノズノレ 31との双 方を移動させても良い。 [0111] また、前述した実施形態では、移動ローラ 26を一対の案内ローラ 24間の中央に設 けている。し力 ながら、本発明では、図 7に示すように、移動ローラ 26を一対の案内 ローラ 24間の中央より電線 3の移動方向 Kの上流側に設けても良い。この場合、移 動ローラ 26より移動方向 Kの下流側の電線 3の曲がりが移動方向 Kの上流側の電線 3の曲がりより緩やかになる。このため、着色ユニット 15に送り出される電線 3の曲がり を抑制できるとともに、電線 3の付与される張力を抑制できる。したがって、電線 3の不 意な破損を防止できる。 [0110] In the above-described embodiment, the electric wire 3 is moved, so that each colored chip 31 of the coloring unit 15 and the electric wire 3 are relatively moved. However, in the present invention, both the electric wire 3 and the colored horns 31 of the coloring unit 15 may be moved even if the colored horns 31 of the coloring unit 15 are moved. [0111] In the above-described embodiment, the moving roller 26 is provided at the center between the pair of guide rollers 24. However, in the present invention, the moving roller 26 may be provided on the upstream side in the moving direction K of the electric wire 3 from the center between the pair of guide rollers 24 as shown in FIG. In this case, the bending of the electric wire 3 on the downstream side in the moving direction K from the moving roller 26 becomes gentler than the bending of the electric wire 3 on the upstream side in the moving direction K. For this reason, the bending of the electric wire 3 sent to the coloring unit 15 can be suppressed, and the tension applied to the electric wire 3 can be suppressed. Therefore, unexpected breakage of the electric wire 3 can be prevented.
[0112] また、前述した実施形態では、加工手段として電線 3を所定の長さに切断する切断 機構 18を設けている。し力、しながら、本発明では、切断機構 18に限ることなぐ電線 3 の端末の被覆部 5を除去する皮むき機構や、電線 3に圧着端子を加締める加締め機 構などの電線 3に種々の加工を施す種々の加工ユニットを設けても良い。  In the embodiment described above, the cutting mechanism 18 that cuts the electric wire 3 to a predetermined length is provided as a processing means. In the present invention, however, the present invention is applied to the electric wire 3 such as a peeling mechanism that removes the coating 5 at the end of the electric wire 3 that is not limited to the cutting mechanism 18 and a crimping mechanism that crimps a crimp terminal to the electric wire 3. Various processing units for performing various processing may be provided.
[0113] また、前述した実施形態では、送り出しローノレ 12は、鉛直方向に沿って並べられて いる。し力しながら、本発明では、送り出しロール 12を水平方向などの鉛直方向以外 の方向に並べても良い。要するに、本発明は、前述した実施形態に限定されることな ぐ送り出しロール 12や各ユニット 13, 14, 15などの配置を適宜変更しても良いこと は勿論である。  [0113] Further, in the above-described embodiment, the delivery lonerets 12 are arranged along the vertical direction. In the present invention, the feeding rolls 12 may be arranged in a direction other than the vertical direction such as the horizontal direction while applying a force. In short, it goes without saying that the arrangement of the delivery roll 12, the units 13, 14, 15 and the like may be appropriately changed without being limited to the above-described embodiment.
[0114] さらに、前述した実施形態では、 自動車に配索されるワイヤハーネスを構成する電 線 3に関して記載している。し力 ながら本発明では、電線 3を自動車に限らず、ポー タブルコンピュータなどの各種の電子機器や各種の電気機械に用いても良いことは 勿論である。  [0114] Further, in the above-described embodiment, the electric wires 3 constituting the wire harness routed to the automobile are described. However, in the present invention, the electric wire 3 may be used not only for an automobile but also for various electronic devices such as a portable computer and various electric machines.
[0115] さらに、本発明では、着色液及び塗料として、アクリル系塗料、インク (染料系、顔料 系）、 UVインクなどの種々のものを用いても良い。なお、前述した実施形態は本発明 の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない 。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。 図面の簡単な説明  [0115] Further, in the present invention, as the coloring liquid and the paint, various paints such as acrylic paints, inks (dye-based, pigment-based), and UV inks may be used. Note that the above-described embodiment merely shows a typical mode of the present invention, and the present invention is not limited to the embodiment. That is, various modifications can be made without departing from the gist of the present invention. BRIEF DESCRIPTION OF THE FIGURES
