Description

本発明は、電線止水処理方法、その方法を実施するために使用される電線止水処理装置、および、当該電線止水処理装置により止水処理されたワイヤハーネスに関する。   The present invention relates to an electric wire water stop treatment method, an electric wire water stop treatment device used for carrying out the method, and a wire harness subjected to a water stop treatment by the electric wire water stop treatment device.

例えば、自動車のエンジンルームと車室内を仕切るパネルにワイヤハーネスを貫通して配索するような場合、パネルに対するワイヤハーネスの貫通部分にはグロメットが装着される。このグロメットは、パネルの取付孔に嵌め込むことにより、パネルとワイヤハーネスの隙間を封じるものであり、グロメットのワイヤハーネス貫通部には、通常、止水処理が施されている。   For example, when a wiring harness is routed through a panel that partitions an engine room and a vehicle interior of an automobile, a grommet is attached to a portion where the wire harness penetrates the panel. This grommet seals the gap between the panel and the wire harness by fitting into the mounting hole of the panel, and a water-stop treatment is usually applied to the wire harness penetration part of the grommet.

特許文献１には、この止水処理方法の一例が記載されている。図４（ａ）〜（ｅ）は、従来のワイヤハーネスの止水処理方法を示す工程説明図である。図５は、ワイヤハーネスをグロメットに装着した状態を示す断面図である。特許文献１の止水処理方法では、まず図４（ａ）に示すように、ワイヤハーネスとなる電線Ｗを束ねた電線束ＷＨを、車両上での配索状態に癖付け成形するための止水部形成治具５００に支持させる。止水部形成治具５００は、電線束ＷＨを支持するために、該止水部形成治具５００上に立設された複数の支持部５０１を備えている。次に、特許文献１の止水処理方法では、支持部５０１に電線束ＷＨが支持されている状態で、該電線束ＷＨの表面に、図４（ｂ）に示すように、止水材塗布ノズル５０５によって、未固化状態の止水材Ｓを塗布する。その後、特許文献１の止水処理方法では、図４（ｃ）に示すように、電線束ＷＨの止水材Ｓを塗布した部分を止水シート５１０でくるむ。   Patent Document 1 describes an example of this water stop treatment method. 4 (a) to 4 (e) are process explanatory views showing a conventional water stopping method for a wire harness. FIG. 5 is a cross-sectional view showing a state where the wire harness is attached to the grommet. In the water stop treatment method of Patent Document 1, first, as shown in FIG. 4 (a), a wire bundle WH in which wires W to be a wire harness are bundled is brazed into a wiring state on a vehicle. The water part forming jig 500 is supported. The water stop part forming jig 500 includes a plurality of support parts 501 erected on the water stop part forming jig 500 in order to support the wire bundle WH. Next, in the water stop processing method of Patent Document 1, the water bundle WH is applied to the surface of the wire bundle WH in a state where the wire bundle WH is supported by the support portion 501 as shown in FIG. The non-solidified water-stopping material S is applied by the nozzle 505. Then, in the water stop processing method of patent document 1, as shown in FIG.4 (c), the part which apply | coated the water stop material S of the wire bundle WH is wrapped with the water stop sheet | seat 510. FIG.

次いで、特許文献１の止水処理方法では、電線束ＷＨを支持部５０１から外した状態にし、止水シート５１０を巻き締めて、電線束ＷＨを円形断面の電線束の形に結束する。さらに、特許文献１の止水処理方法では、図４（ｄ）、（ｅ）に示すように、止水シート５１０の両端にテープ５１２を巻き付けて、電線束ＷＨの断面形状を、図５に示すグロメット６００のワイヤハーネス貫通部６０２に挿通可能な断面形状に整形し、グロメット６００に挿通させる。これにて、止水構造が完成する。なお、６０１はグロメットのパネル嵌合部である。   Next, in the water stop processing method of Patent Document 1, the wire bundle WH is removed from the support portion 501, the water stop sheet 510 is wound up, and the wire bundle WH is bound into a circular cross-section wire bundle. Furthermore, in the water stop processing method of Patent Document 1, as shown in FIGS. 4D and 4E, tape 512 is wound around both ends of the water stop sheet 510, and the cross-sectional shape of the wire bundle WH is shown in FIG. The grommet 600 is shaped into a cross-sectional shape that can be inserted into the wire harness penetration portion 602 of the grommet 600 shown in FIG. This completes the water stop structure. Reference numeral 601 denotes a grommet panel fitting portion.

また、他の止水処理方法として、グロメットに電線束を通した状態で止水材を注入する方法もある。即ち、その方法では、電線束をグロメットのワイヤハーネス貫通部に予め挿通させ、その状態で、ワイヤハーネス貫通部の内部に止水材を充填することにより、グロメットとワイヤハーネスの隙間やワイヤハーネスを構成する電線間の隙間を止水する。
特開２００５−７１７９０号公報（図４、図５） Moreover, there exists the method of inject | pouring a water stop material in the state which passed the wire bundle through the grommet as another water stop processing method. That is, in that method, the wire bundle is inserted in advance through the wire harness penetration part of the grommet, and the gap between the grommet and the wire harness or the wire harness is filled by filling the inside of the wire harness penetration part in that state. Stops the gap between the wires that make up.
Japanese Patent Laying-Open No. 2005-71790 (FIGS. 4 and 5)

ところで、図４（ａ）〜（ｅ）に示した従来の方法では、外部から止水材Ｓを塗布したあと、その部分を止水シート５１０で巻き締めるだけであるから、止水材Ｓが電線Ｗ間に存在する微細な隙間に十分に行き渡らず、そのために止水処理が不十分になる可能性がある。また、グロメットに電線束を挿通させた後に止水材を充填する方法の場合も、同様な可能性がある。そのため、従来のワイヤハーネス製造方法では、止水処理が十分でない可能性のあるワイヤハーネスが製造され得ることから、ワイヤハーネスの止水状態を確認するテストをしなければならず、ワイヤハーネスの製造効率が下がってしまう問題があった。   By the way, in the conventional method shown to Fig.4 (a)-(e), after apply | coating the water stop material S from the outside, since the part is only wound up with the water stop sheet 510, the water stop material S is The fine gaps existing between the electric wires W are not sufficiently spread, so that the water stop treatment may be insufficient. Moreover, the same possibility exists also in the case of the method of filling a water stop material after inserting an electric wire bundle in a grommet. Therefore, in the conventional wire harness manufacturing method, a wire harness that may not be sufficiently water-stopped can be manufactured. Therefore, a test for confirming the water-stop state of the wire harness must be performed, and the wire harness is manufactured. There was a problem that efficiency decreased.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、電線間の隙間を確実に封じ、高い止水性能を発揮することができて、ワイヤハーネス等の電線束に効率良く止水処理を施すことができる電線止水処理方法、その方法を実施するために使用される電線止水処理装置、および、該電線止水処理装置により止水処理された電線束を備えたワイヤハーネスを提供することにある。   This invention is made | formed in view of the situation mentioned above, The objective can seal the space | interval between electric wires reliably and can exhibit high water stop performance, and it is efficient for electric wire bundles, such as a wire harness. Wire water stop treatment method capable of performing water stop treatment, wire water stop treatment device used for carrying out the method, and wire provided with a bundle of wires subjected to water stop treatment by the wire water stop treatment device To provide a harness.

By heating the movable clamp mechanism 21 that pulls the wire bundle WH linearly along the longitudinal direction to form one wire bundle WH and the portion where the granular water blocking material S adheres, And a heating device 20 that heats the granular water-stopping material S attached to the outer periphery.

次に、上記構成の電線止水処理装置を用いて行なうワイヤハーネスの電線束に止水処理を行なう手順について説明する。
一般に、ワイヤハーネスを組み立てる場合、例えば、作業員が所定の組立作業台上に、設計図等を参照しながら、複数本の電線を取り付けていき、これらを所定形状に配索していく。更に作業員は、例えば、電線の所定箇所にプロテクタや樹脂チューブあるいはクリップ等の部品を組み付けたり、テープを巻き付けたりして、所定形状のワイヤハーネスを形成していく。 Next, a procedure for performing the water stop treatment on the wire bundle of the wire harness performed using the wire water stop treatment apparatus having the above configuration will be described.
Generally, when assembling a wire harness, for example, an operator attaches a plurality of electric wires on a predetermined assembly work table while referring to a design drawing or the like, and routes them in a predetermined shape. Further, for example, the worker assembles parts such as a protector, a resin tube, or a clip at a predetermined portion of the electric wire, or wraps a tape to form a wire harness having a predetermined shape.

このワイヤハーネスの電線束に対してさらに止水処理を施す止水処理方法の手順を以下に説明する。
まず、電線束ＷＨを構成する複数の電線Ｗを適度にばらけた状態にし、図１（ａ）に示すように、電線束ＷＨの止水処理予定部Ｔを、投入口１１から箱体１０内に挿入する。そして挿入した状態で、粉粒体舞わせ装置１５として設けられたファンを作動させることにより、箱体１０の内部に粉粒状の止水材Ｓが霧状に浮遊滞在する環境を作り出し、それにより、その環境に晒された各電線Ｗの外周に止水材Ｓを付着させる（止水材付着工程）。この際、先に箱体１０内部に粉粒状の止水材Ｓが舞った環境を作り出しておき、その状態で、箱体１０内に電線束ＷＨの止水処理予定部Ｔを挿入しても、同様に、各電線Ｗの外周に止水材Ｓを付着させることができる。 The procedure of the water stop processing method which performs further a water stop process with respect to the wire bundle of this wire harness is demonstrated below.
First, the plurality of electric wires W constituting the electric wire bundle WH are appropriately dispersed, and the water stop treatment scheduled portion T of the electric wire bundle WH is inserted into the box 10 from the insertion port 11 as shown in FIG. Insert into. And in the inserted state, by operating the fan provided as the granular material fluttering device 15, an environment in which the granular water-stopping material S stays in a mist state in the box 10 is created, thereby The water-stopping material S is attached to the outer periphery of each electric wire W exposed to the environment (water-stopping material attaching step). At this time, even if the environment in which the granular water-stopping material S flew in the box 10 is created first, and the water-stopping scheduled portion T of the wire bundle WH is inserted into the box 10 in this state, Similarly, the water stop material S can be adhered to the outer periphery of each electric wire W.

このように、適度にばらけた状態の複数の電線Ｗを、粉粒状の止水材Ｓが舞う環境に晒すことで、各電線Ｗの外周面にムラ無く粉粒状の止水材Ｓを付着させることができるため効率が良い。   In this way, by exposing the plurality of electric wires W in a moderately dispersed state to an environment where the granular water-stopping material S dances, the granular water-stopping material S adheres to the outer peripheral surface of each electric wire W without unevenness. Can be efficient.

なお、この止水材付着工程を実行する際に、粉粒状の止水材Ｓ及び複数の電線それぞれの外周面の少なくとも一方に静電気を帯電させておくことにより、静電気によって粉粒状の止水材が静電気によって各電線の外周面に誘導させる作用が生じて、止水材を各電線により一層付着させやすくなり、ムラ無く止水材Ｓを電線Ｗの外周に付着させることができるため止水処理の効率がより向上する。   In addition, when performing this water-stop material adhesion process, by charging static electricity to at least one of the powder water-stop material S and the outer peripheral surfaces of each of the plurality of electric wires, the powder water-stop material is caused by static electricity. Causes static electricity to be guided to the outer peripheral surface of each electric wire, making it easier to adhere the water-stopping material to each electric wire and allowing the water-stopping material S to adhere to the outer periphery of the electric wire W without any unevenness. The efficiency is improved.

また、粉粒状の止水材Ｓを複数の電線Ｗそれぞれの外周に付着させる前に、各電線Ｗの外周に、粉粒状の止水材Ｓの付着を促すための液体、例えば糊状の液体などを、スプレー等で付着させておくことにより、止水材Ｓが各電線Ｗの外周面に付着しやすく、かつ、一旦電線Ｗに付着した止水材Ｓが取れにくくなるため、止水材Ｓを電線Ｗの外周により確実にムラ無く付着させることができる。   Further, before adhering the powdery water-stopping material S to the outer circumferences of the plurality of electric wires W, a liquid for promoting the adhering of the powdery water-stopping material S to the outer circumferences of the electric wires W, for example, paste-like liquid Is adhered to the outer peripheral surface of each electric wire W, and it becomes difficult to remove the water-stopping material S once attached to the electric wires W. S can be reliably adhered to the outer periphery of the electric wire W without unevenness.

次に、上述の止水材付着工程が終わったら、電線束ＷＨを箱体１０から取り出し、図１（ｂ）に示すように、取り出された電線束ＷＨにおける、止水材Ｓが付着している部分の両側の把持部分を収束加熱装置２の可動クランプ装置２１で把持し、その状態で、可動クランプ装置２１を矢印Ｆ１のように互いに離間する方向に動かす。こうすることで、弛んだ複数の電線Ｗに引っ張り力を加えて、一つの電線束ＷＨにする。   Next, when the above-mentioned water-stopping material adhering step is finished, the electric wire bundle WH is taken out from the box 10, and the water-stopping material S in the taken-out electric wire bundle WH is attached as shown in FIG. The gripping portions on both sides of the portion being held are gripped by the movable clamp device 21 of the convergence heating device 2, and in this state, the movable clamp device 21 is moved away from each other as indicated by an arrow F1. In this way, a tensile force is applied to the plurality of loosened electric wires W to form one electric wire bundle WH.

その際、ばらけた状態の複数の電線Ｗが１本に収束する段階で、ドライヤー等の加熱装置２０から温風を、止水材Ｓが付着した箇所に当てる。すると、複数の電線Ｗが収束しつつ、各電線Ｗの外周に付着した止水材Ｓが加熱によって溶融し、粉粒状の止水材Ｓが付着した部分それぞれが、複数の電線Ｗの間に溶融した止水材Ｓを介在させた状態のまま、一体化する（収束加熱工程）。なお、温風にて止水材Ｓが付着した箇所を過熱する場合には、電線Ｗに付着した止水材Ｓが温風によって吹き飛ばされないよう、上述した静電気の効果や液体などによって止水材Ｓの電線Ｗへの付着を促すことが好ましい。こうして、止水処理部ＳＨを有するワイヤハーネスが出来上がる。この電線束ＷＨは、図５に示したものと同様に、グロメットに挿入され、該グロメットによって電線束ＷＨの止水処理部ＳＨが加締められることで、グロメットと電線束間の止水構造を実現することができる。   At that time, at the stage where a plurality of separated electric wires W converge to one, hot air is applied from the heating device 20 such as a dryer to the place where the water stop material S is attached. Then, while the plurality of electric wires W converge, the water-stopping material S attached to the outer periphery of each electric wire W is melted by heating, and each portion where the powdery water-stopping material S is attached is between the electric wires W. It integrates with the molten water stop material S interposed (convergence heating process). In addition, when the location where the water-stopping material S adheres with hot air, the water-stopping material S due to the above-described static electricity effect or liquid is used so that the water-stopping material S attached to the electric wire W is not blown away by the hot air. It is preferable to promote the adhesion of S to the electric wire W. Thus, a wire harness having the water stop treatment portion SH is completed. This wire bundle WH is inserted into the grommet in the same manner as shown in FIG. 5, and the water stop treatment portion SH of the wire bundle WH is crimped by the grommet, so that a water stop structure between the grommet and the wire bundle is obtained. Can be realized.

なお、温風を吹き当てるタイミングは、電線束ＷＨが完全に収束した後でも、完全に収束する前でもよい。完全に収束する前に温風を吹き当てる場合は、ばらけた電線Ｗがまだ密に接触していない状態で温風が当たることになるので、くまなく温風を電線Ｗの隙間に行き渡らせることができ、止水材Ｓが溶融しやすくなる。従って、ある程度の隙間が残っている完全収束の前段階から温風を吹き当てつつ、完全収束させることが、止水材Ｓを加熱により溶融させて一体化させる上では最も好ましい。   The timing of blowing the hot air may be after the wire bundle WH has completely converged or before it has completely converged. If hot air is blown before it completely converges, the hot air will be applied in a state where the loose wires W are not yet in close contact with each other. The water-stopping material S is easily melted. Accordingly, it is most preferable that the water stop material S is melted by heating to be integrated while blowing warm air from the previous stage of complete convergence where some gap remains.

以上のように、本実施形態では、粉粒状の止水材Ｓを、ばらけた状態の各電線Ｗの外周に付着させた後に、複数の電線Ｗを収束させつつ、粉粒状の止水材Ｓが付着した部分を加熱して粉粒状を溶融させることで一体化させるのため、電線Ｗ間の隙間に確実に止水材Ｓを行き渡らせることができる。従って、電線Ｗ間の隙間を確実に封じることができ、高い止水性能を発揮することができる。そのため、事後の止水テストを省略することも可能となり、ワイヤハーネスに効率良く止水処理を行なうことができる。なお、本実施形態では、ワイヤハーネスに備えられる電線束を例に説明したが、止水処理が施されるその他の電線束に適用することができる。   As mentioned above, in this embodiment, after attaching granular water-proof material S to the outer periphery of each electric wire W in the state of being scattered, while making a plurality of electric wires W converge, granular water-proof material S Therefore, the water-stopping material S can be reliably distributed in the gaps between the electric wires W. Therefore, the clearance gap between the electric wires W can be sealed reliably, and high water stop performance can be exhibited. Therefore, it becomes possible to omit the subsequent water stop test, and the water stop can be efficiently performed on the wire harness. In addition, in this embodiment, although the electric wire bundle with which a wire harness is provided was demonstrated to the example, it is applicable to the other electric wire bundle to which a water stop process is performed.

特に、本実施形態では、粉粒状の止水材Ｓを空中に霧状に舞わせた環境に、電線Ｗをばらけた状態で晒すことによって、各電線Ｗの外周に止水材Ｓを付着させるので、ムラ無く止水材Ｓを電線Ｗの外周に付着させることができ、収束加熱工程によって、溶融された止水材Ｓが複数の電線Ｗ間の隙間に、より確実に止水材を行き渡らせることができる。このため、止水処理を効率良く行なうことができる。   In particular, in this embodiment, the water-stopping material S is attached to the outer periphery of each electric wire W by exposing the electric wire W to an environment in which the granular water-stopping material S is mist-like in the air. Therefore, the water-stopping material S can be adhered to the outer periphery of the electric wire W without unevenness, and the melted water-stopping material S is more reliably distributed in the gaps between the plurality of electric wires W by the convergence heating process. Can be made. For this reason, a water stop process can be performed efficiently.

＜第２実施形態＞
図２は本発明にかかる電線止水処理方法および電線止水処理装置の第２実施形態を説明する図である。図２に示すように、本実施形態では、第１実施形態とは、温風吹き出し式の加熱装置２０の代わりに、以下に説明する加熱装置３０を備えている点で相違する。加熱装置３０は、上壁３２と下壁３３とを連結壁３４で繋いだＵ字状を有する。上壁３２と下壁３３との間には、電線束ＷＨを挿入可能な挿入溝３１が形成される。また、上壁３２と下壁３３とのそれぞれの内部には電熱線ヒータ３５が設けられている。挿入溝３１に、ばらけた状態で、各電線の外周面に粉粒状の止水材Ｓが付着した部分を挿入させた状態で、電熱線ヒータ３５に電気を流して発熱させると、挿入された複数の電線の止水材Ｓが付着した部分が加熱される。ここで、複数の電線Ｗに粉粒状の止水材Ｓを付着させる止水材付着工程として、加熱装置３０による加熱前に、上記第１実施形態の止水材付着装置１を用いて予め複数の電線Ｗに止水材Ｓを付着させておくことができる。 Second Embodiment
FIG. 2 is a view for explaining a second embodiment of the wire water stop treatment method and the wire water stop treatment apparatus according to the present invention. As shown in FIG. 2, this embodiment is different from the first embodiment in that a heating device 30 described below is provided instead of the hot air blowing type heating device 20. The heating device 30 has a U shape in which an upper wall 32 and a lower wall 33 are connected by a connecting wall 34. An insertion groove 31 into which the wire bundle WH can be inserted is formed between the upper wall 32 and the lower wall 33. A heating wire heater 35 is provided in each of the upper wall 32 and the lower wall 33. In the state where the insertion groove 31 is separated and the portion where the granular water blocking material S is attached to the outer peripheral surface of each electric wire is inserted into the insertion groove 31 when electricity is passed through the heating wire heater 35 to generate heat. The part to which the waterproof material S of the some electric wire adhered is heated. Here, as the water-stopping material attaching step for attaching the powdery water-stopping material S to the plurality of electric wires W, a plurality of water-stopping material attaching devices 1 according to the first embodiment are used in advance before heating by the heating device 30. The water stop material S can be adhered to the electric wire W.

本実施形態においても、数の電線をその長手方向に沿って直線状に引っ張って一つの電線束にする可動クランプ機構を備えた構成とすることができる。
すなわち、止水材付着工程が済んだ複数の電線Ｗを箱体１０から取り出して、止水材Ｓが付着している部分の両側の把持部分を可動クランプ装置２１により把持させ、複数の電線をその長手方向に直線状に引っ張ることで、複数の電線Ｗを１つの電線束に収束させる。このとき、ばらけた状態の複数の電線Ｗが１つの電線束ＷＨにまとまる段階で、加熱装置３０の電熱線ヒータ３５を作動させて、止水材Ｓが付着した箇所を加熱し、止水材Ｓを加熱により溶融させて一体化する（収束加熱工程）。 Also in this embodiment, it can be set as the structure provided with the movable clamp mechanism which pulls a several electric wire linearly along the longitudinal direction, and makes it one electric wire bundle.
That is, the plurality of electric wires W that have been subjected to the water-stopping material adhering step are taken out of the box 10, the gripping portions on both sides of the portion to which the water-stopping material S is attached are gripped by the movable clamp device 21, By pulling linearly in the longitudinal direction, the plurality of electric wires W are converged into one electric wire bundle. At this time, at the stage where a plurality of separated wires W are gathered into one wire bundle WH, the heating wire heater 35 of the heating device 30 is operated to heat the portion where the water blocking material S adheres, S is melted and integrated by heating (convergence heating step).

＜第３実施形態＞
図３（ａ）〜（ｃ）は、本発明にかかる電線止水処理方法および電線止水処理装置の第３実施形態の説明図である。 <Third Embodiment>
Drawing 3 (a)-(c) is an explanatory view of a 3rd embodiment of an electric wire water stop processing method and an electric wire water stop processing device concerning the present invention.

本実施形態の電線止水処理装置は、図３（ｂ）に示す止水材付着装置１０１と、図３（ｃ）に示す収束加熱装置１０２とを備えている。   The wire water stop treatment apparatus of this embodiment includes a water stop material adhering apparatus 101 shown in FIG. 3B and a convergence heating apparatus 102 shown in FIG.

図３（ｂ）に示す止水材付着装置１０１は、粉粒状の止水材Ｓを空中に霧状に舞わせる部屋（密閉空間であっても、一部が開口した空間であってもよい。）１０５と、粉粒状の止水材Ｓを空中に舞わせる粉粒体舞わせ装置（図示略）を有している。粉粒体舞わせ装置としては、第１実施形態のようにファンを用いる以外に、止水材Ｓを粉粒状に吹き付ける粉体スプレー等も用いることができる。部屋１０５は、止水処理時に、複数の電線Ｗの止水処理予定部Ｔを処理経路Ｋに沿って自在に通過するように制御可能である。この処理経路Ｋに沿って、止水処理に必要な一連の流れ作業が行われる。   The water-stopping material adhering device 101 shown in FIG. 3B may be a room (a sealed space or a partly open space) in which the granular water-stopping material S is made to mist in the air. .) 105, and a powdered body dancing device (not shown) for causing the powdery water-stopping material S to float in the air. As the granular material fluttering device, a powder spray or the like for spraying the water-stopping material S onto the granular material can be used in addition to using a fan as in the first embodiment. The room 105 can be controlled so as to freely pass through the water stop treatment scheduled portion T of the plurality of electric wires W along the treatment path K during the water stop treatment. A series of flow operations necessary for the water stop treatment are performed along the treatment path K.

図３（ｃ）に示す収束装置１０２は、可動クランプ機構２１と、加熱装置１１０とから構成されている。なお、この加熱装置１１０は、ドライヤーのように温風を吹き当てる形式でも、電熱線ヒータ等の輻射熱で加熱する形式でもよい。止水材付着装置１０１の部屋１０５と加熱装置１１０とは、図３中の矢印で示すように、複数の電線Ｗの止水処理予定部Ｔに対して相対的に処理経路Ｋに沿って移動可能であり、同処理経路Ｋに沿って並べて配置されている。   A converging device 102 shown in FIG. 3C includes a movable clamp mechanism 21 and a heating device 110. The heating device 110 may be a type that blows warm air like a dryer or a type that heats by radiant heat such as a heating wire heater. The room 105 and the heating device 110 of the water stop material adhering apparatus 101 move along the processing path K relative to the water stop processing scheduled portion T of the plurality of electric wires W as indicated by arrows in FIG. They are possible and are arranged side by side along the processing path K.

また、一対の可動クランプ機構２１は、図３（ａ）に示す電線ばらし位置から、図３（ｃ）に示す加熱装置１１０を通過する位置まで、処理経路Ｋに沿って搬送移動可能になっていると共に、電線束ＷＨの長手方向に沿って移動させることができる。そして、一対の可動クランプ機構２１は、図３（ａ）に示すように止水処理予定部Ｔの両側で電線束ＷＨを把持した状態で、互いに接近する方向（矢印Ｆ２方向）に移動させられることにより、止水処理予定部Ｔの電線Ｗを適度に弛ませ、複数の電線Ｗをばらけた状態とすることができる。   In addition, the pair of movable clamp mechanisms 21 can be moved along the processing path K from the wire separation position shown in FIG. 3A to the position passing through the heating device 110 shown in FIG. And can be moved along the longitudinal direction of the wire bundle WH. And a pair of movable clamp mechanism 21 is moved in the direction (arrow F2 direction) which mutually approaches in the state which gripped the wire bundle WH on both sides of the water stop process scheduled part T, as shown to Fig.3 (a). Thereby, the electric wire W of the water stop process scheduled part T can be loosened moderately, and it can be set as the state which several electric wires W were scattered.

次に、上記構成の止水処理装置を用いて行なうワイヤハーネスの電線束の止水処理方法について説明する。   Next, the water stop processing method of the wire bundle of the wire harness performed using the water stop processing apparatus of the said structure is demonstrated.

このワイヤハーネスの電線束に対してさらに止水処理を施す電線止水処理方法の手順を以下に説明する。
まず、図３（ａ）に示すように、一対に可動クランプ機構２１により、止水処理予定部Ｔの両側で複数の電線Ｗの把持部分を把持し、その状態で、互いに接近する方向（矢印Ｆ２方向）に可動クランプ機構２１を移動させることにより、止水処理予定部Ｔの複数の電線Ｗを弛ませ、各電線Ｗを適度にばらけさせる。 The procedure of the electric wire water stop processing method which performs further water stop processing with respect to the wire bundle of this wire harness is demonstrated below.
First, as shown in FIG. 3 (a), a pair of movable clamp mechanisms 21 grips the grip portions of the plurality of electric wires W on both sides of the water stop treatment scheduled portion T, and in such a state, the directions approach each other (arrows). By moving the movable clamp mechanism 21 in the F2 direction), the plurality of electric wires W of the water stop treatment scheduled portion T are loosened, and each electric wire W is appropriately dispersed.

次に複数の電線Ｗをばらけさせた状態で、図３（ｂ）に示すように、電線束ＷＨの止水処理予定部Ｔを止水材付着装置１０１の部屋１０５に搬送する。そして、この部屋１０５で、粉粒状の止水材Ｓが霧状に浮遊滞在する環境を作り出し、その環境に複数の電線Ｗを晒すことで、各電線Ｗの外周に止水材Ｓを付着させる（止水材付着工程）。   Next, in a state where the plurality of electric wires W are separated, the water stop treatment scheduled portion T of the wire bundle WH is transferred to the room 105 of the water stop material adhering apparatus 101 as shown in FIG. And in this room 105, the environment where the granular water-stopping material S stays in a mist state is created, and the water-stopping material S is attached to the outer periphery of each electric wire W by exposing the plurality of wires W to the environment. (Waterproof material adhesion process).

このように、複数の電線Ｗを適度にばらけた状態にして、粉粒状の止水材Ｓが舞う環境に置くことで、各電線Ｗの外周にムラ無く粉粒状の止水材Ｓを付着させることができるため、止水処理の効率が良い。   In this way, by placing the plurality of electric wires W in a moderately dispersed state and placing them in an environment where the powdery water-stopping material S dances, the powdery water-stopping material S adheres uniformly to the outer periphery of each electric wire W. Therefore, the efficiency of the water stop treatment is good.

なお、この止水材付着工程を実行する際に、粉粒状の止水材Ｓ及び前記複数の電線それぞれの外周面の少なくとも一方に静電気を帯電させることにより、静電気によって粉粒状の止水材を各電線により一層付着させやすくなり、ムラ無く止水材Ｓを電線Ｗの外周に付着させることができる。   In addition, when performing this water-stop material adhesion process, by charging static electricity to at least one of the granular water-stop material S and the outer peripheral surfaces of each of the plurality of electric wires, the powder water-stop material is caused by static electricity. It becomes easier to adhere to each electric wire, and the water stop material S can be adhered to the outer periphery of the electric wire W without any unevenness.

また、粉粒状の止水材Ｓを各電線Ｗの外周に付着させる前に、各電線Ｗの外周に、粉粒状の止水材Ｓの付着を促すための液体、例えば糊状の液体などを、スプレー等で付着させてもよい。こうすれば、止水材Ｓが各電線Ｗの外周面に付着しやすく、かつ、一旦電線Ｗに付着した止水材Ｓが取れにくくなるため、止水材Ｓを電線Ｗの外周により確実にムラ無く付着させることができる。   Further, before adhering the granular water-stopping material S to the outer periphery of each electric wire W, a liquid for promoting the adhering of the granular water-stopping material S to the outer periphery of each electric wire W, such as a paste-like liquid, is provided. Alternatively, it may be adhered by spraying or the like. If it carries out like this, since the water stop material S tends to adhere to the outer peripheral surface of each electric wire W and it becomes difficult to remove the water stop material S once attached to the electric wire W, the water stop material S is more reliably attached to the outer periphery of the electric wire W. Can be attached without unevenness.

次に、上述の部屋１０５から電線束ＷＨの止水材処理予定部Ｔを次の加熱装置１１０に移動する。それと共に、図３（ｃ）に示すように、収束装置１０２の可動クランプ装置２１を矢印Ｆ１のように互いに離間する方向に動かして、弛んだ複数の電線Ｗに引っ張り力を加え、１つの電線束ＷＨにまとめる。   Next, the water blocking material processing scheduled portion T of the wire bundle WH is moved from the room 105 to the next heating device 110. At the same time, as shown in FIG. 3 (c), the movable clamping device 21 of the converging device 102 is moved in a direction away from each other as indicated by an arrow F1, and a tensile force is applied to the plurality of loosened wires W. Put it in a bundle WH.

ばらけた状態の複数の電線Ｗを１本の電線束ＷＨにまとまる段階で、加熱装置２０により熱を加えることにより、各電線Ｗの外周に付着した止水材Ｓを、加熱により溶融させて一体化する（収束加熱工程）。これにより、止水処理部ＳＨを有するワイヤハーネスが出来上がる。この電線束ＷＨは、図５に示したものと同様に、グロメットに挿入され、該グロメットによって電線束ＷＨの止水処理部ＳＨが加締められることで、グロメットと電線束間の止水構造を実現することができる。   At the stage where a plurality of separated wires W are gathered into one wire bundle WH, heat is applied by the heating device 20 so that the water stop material S attached to the outer periphery of each wire W is melted by heating and integrated. (Convergence heating process). Thereby, the wire harness which has the water stop process part SH is completed. This wire bundle WH is inserted into the grommet in the same manner as shown in FIG. 5, and the water stop treatment portion SH of the wire bundle WH is crimped by the grommet, so that a water stop structure between the grommet and the wire bundle is obtained. Can be realized.

以上のように、本実施形態では、粉粒状の止水材Ｓを、ばらけた状態の各電線Ｗの外周に付着させた後に、複数の電線Ｗを収束させつつ、各電線Ｗの外周に付着した粉粒状の止水材Ｓを加熱により溶融させ一体化させるので、電線Ｗ間の隙間に確実に止水材Ｓを行き渡らせることができる。従って、電線Ｗ間の隙間を確実に封じることができ、高い止水性能を発揮することができる。そのため、事後の止水テストを省略することも可能となり、ワイヤハーネスの製造効率の向上を図ることができる。   As described above, in this embodiment, after the granular water-stopping material S is attached to the outer periphery of each separated electric wire W, the plurality of electric wires W are converged and attached to the outer periphery of each electric wire W. Since the powdered water-stopping material S is melted and integrated by heating, the water-stopping material S can be reliably distributed in the gaps between the electric wires W. Therefore, the clearance gap between the electric wires W can be sealed reliably, and high water stop performance can be exhibited. Therefore, it becomes possible to omit the subsequent water stop test, and the production efficiency of the wire harness can be improved.

特に、本実施形態では、粉粒状の止水材Ｓを空中に霧状に舞わせた環境に、電線Ｗをばらけた状態で晒すことによって、各電線Ｗの外周に止水材Ｓを付着させるので、ムラ無く止水材Ｓを電線Ｗの外周に付着させることができ、次の収束加熱工程で付着させた止水材Ｓを一体化させることで、複数の電線Ｗ間の隙間により確実に止水材Ｓを行き渡らせることができる。   In particular, in this embodiment, the water-stopping material S is attached to the outer periphery of each electric wire W by exposing the electric wire W to an environment in which the granular water-stopping material S is mist-like in the air. Therefore, the water-stopping material S can be adhered to the outer periphery of the electric wire W without unevenness, and the water-stopping material S attached in the next convergent heating process is integrated, so that the gap between the plurality of electric wires W can be reliably secured. The water blocking material S can be distributed.

また、処理経路Ｋに沿って電線束ＷＨを移動させながら、順番に処理を加えることができるので、流れ作業で処理を実施することができ、効率よく作業を進めることができる。また、可動クランプ機構２１で、複数の電線Ｗをばらけた状態とすることができるので、チャッキングした状態を維持しながら一連の処理を効率良く行なうことができる。   In addition, since the processing can be sequentially performed while moving the wire bundle WH along the processing path K, the processing can be performed by a flow operation, and the operation can be efficiently performed. In addition, since the plurality of electric wires W can be separated by the movable clamp mechanism 21, a series of processes can be performed efficiently while maintaining the chucked state.
