A plurality of metallic wires with spiral winding parts 2 formed at ends are bundled in parallel, and thermoplastic resin powder 10 is made to electrostatically adhere to the outer surfaces of the plurality of bundled wires by an electrostatic coating device 9. After that, the adhering thermoplastic resin powder 10 is heated and melted, and the plurality of wires bundled in parallel are integrated with each other by melted thermoplastic resin.

Description

この発明は、電柱関係の支線、メッセンジャーワイヤーの引き留め又は接続、落石防護網のワイヤーロープの引き留め等に使用される巻付けグリップの製造方法に関するものである。   The present invention relates to a method of manufacturing a winding grip used for a utility pole-related branch line, messenger wire retention or connection, falling rock protection net wire rope retention, and the like.

巻付けグリップ１は、図１に示すように、亜鉛・アルミ合金めっき鋼線等の金属製の線材を複数本並列に束ねたものであり、その端部に螺旋状の巻付け部２を有する。   As shown in FIG. 1, the winding grip 1 is formed by bundling a plurality of metal wires such as zinc / aluminum alloy-plated steel wires in parallel, and has a spiral winding portion 2 at an end thereof. .

この巻付けグリップ１は、図２（ａ）〜（ｄ）に示すように、ワイヤーロープ３に、螺旋状の巻付け部２を巻き付けることによって、ワイヤーロープ３を確実かつ容易に引き留めることができる。   As shown in FIGS. 2A to 2D, the winding grip 1 can reliably and easily hold the wire rope 3 by winding the spiral winding portion 2 around the wire rope 3. .

巻付けグリップ１は、上記のように、線材を複数本並列に束ねたものであり、束ねた線材がばらけないように、外面が接着剤によって一体に固められている。   As described above, the winding grip 1 is formed by bundling a plurality of wire rods in parallel, and the outer surface is solidified by an adhesive so that the bundled wire rods are not scattered.

そして、巻付けグリップ１の巻付け部２の内面には、ワイヤーロープ３との滑りを防止するために、アルミナ質研磨材等の摩擦増加剤が塗布されている。   A friction increasing agent such as an alumina abrasive is applied to the inner surface of the winding portion 2 of the winding grip 1 in order to prevent slipping with the wire rope 3.

この種の巻付けグリップ１は、特許文献１、特許文献２にも開示されている。   This type of winding grip 1 is also disclosed in Patent Document 1 and Patent Document 2.

特開平８−２６５９４１号公報JP-A-8-265941 特開平８−１５５５７１号公報JP-A-8-155571

ところで、従来、巻付けグリップ１の外面に塗布される接着剤としては、溶剤系のビニル系接着剤が使用されている。   By the way, conventionally, as the adhesive applied to the outer surface of the winding grip 1, a solvent-based vinyl adhesive has been used.

従来、この溶剤系の接着剤４の塗布には、図３に示すような、溶剤系の接着剤４が流れるカーテンフローコーター５を使用し、巻付けグリップ１を、カーテンフローコーター５内を通過させることによって、巻付けグリップ１の束ねた線材間に接着剤４を浸透させ、その後に、乾燥炉６を経由させることによって接着剤４を固化させている。   Conventionally, the solvent-based adhesive 4 is applied by using a curtain flow coater 5 through which the solvent-based adhesive 4 flows as shown in FIG. 3, and the winding grip 1 passes through the curtain flow coater 5. Thus, the adhesive 4 is infiltrated between the bundled wires of the winding grip 1, and then the adhesive 4 is solidified by passing through the drying furnace 6.

この後、巻付けグリップ１の巻付け部２の内側に、アルミナ質研磨剤等の摩擦増加剤７を付着させて、巻付け部２の摩擦効果を向上させている。   Thereafter, a friction increasing agent 7 such as an alumina abrasive is attached to the inside of the winding portion 2 of the winding grip 1 to improve the friction effect of the winding portion 2.

この巻付け部２への摩擦増加剤７の付着は、乾燥炉６から引き出した巻付けグリップ１を回転させながら、巻付け部２に接着剤８を塗布して行っている。   The adhesion of the friction increasing agent 7 to the winding part 2 is performed by applying the adhesive 8 to the winding part 2 while rotating the winding grip 1 drawn from the drying furnace 6.

ところが、巻付けグリップ１の線材の固定に溶剤系のビニル系接着剤を使用する上記従来の方法は、ＶＯＣやＣＯ２の面で環境に優しくないという問題がある。 However, the conventional method using a solvent-based vinyl adhesive for fixing the wire rod of the winding grip 1 has a problem that it is not environmentally friendly in terms of VOC and CO 2 .

そこで、この発明は、溶剤系の接着剤を使用することなく、巻付けグリップの線材を一体に固定することができる環境に優しい巻付けグリップの製造方法を提供することを課題とする。   Therefore, an object of the present invention is to provide an environment-friendly manufacturing method for a winding grip that can fix the winding grip wire together without using a solvent-based adhesive.

この発明の巻付けグリップの製造方法は、端部に螺旋状の巻付け部を形成した金属製の複数本の線材を並列に束ね、この束ねた複数本の線材の外表面に、熱可塑性樹脂の粉体を静電塗装装置によって静電気的に付着させ、その後、付着させた熱可塑性樹脂の粉体を加熱熔融させ、熔融した熱可塑性樹脂によって並列に束ねた複数本の線材を一体化することを特徴とする。   In the manufacturing method of the winding grip of the present invention, a plurality of metal wires each having a spiral winding portion formed at an end thereof are bundled in parallel, and a thermoplastic resin is formed on the outer surface of the bundled wires. The powder is adhered electrostatically with an electrostatic coating device, then the adhered thermoplastic resin powder is heated and melted, and a plurality of wires bundled in parallel by the melted thermoplastic resin are integrated. It is characterized by.

この後、螺旋状の巻付け部の内側には、引き留め作業を行う際に、ワイヤーロープとの滑りを防止する、アルミナ質研磨材等の摩擦増加剤が接着することにより、巻付けグリップを完成させる。   After this, a friction increasing agent such as an alumina abrasive that prevents slipping with the wire rope is adhered to the inside of the spiral winding part to complete the winding grip. Let

この摩擦増加剤の接着方法として、次のような方法を採用することができる。   The following method can be employed as a method for adhering the friction increasing agent.

その一つは、巻付け部の内側に接着剤を塗布し、この接着剤の上に、摩擦増加剤を散布して接着するという方法である。   One of them is a method in which an adhesive is applied to the inside of the winding portion, and a friction increasing agent is sprayed and bonded onto the adhesive.

また、並列に束ねた複数本の線材の外表面に付着する熱可塑性樹脂の粉体を加熱溶融する際に、螺旋状の巻付け部の内側に摩擦増加剤を散布し、複数本の線材の固定と共に、摩擦増加剤を接着するという方法を採用してもよい。   In addition, when the thermoplastic resin powder adhering to the outer surface of a plurality of wires bundled in parallel is heated and melted, a friction increasing agent is sprayed on the inner side of the spirally wound portion, You may employ | adopt the method of adhere | attaching a friction increasing agent with fixation.

また、並列に束ねた複数本の線材を固定する熱可塑性樹脂の粉体に、予め摩擦増加剤を混合しておき、熱可塑性樹脂の粉体と共に、摩擦増加剤を静電塗装装置により吹き付け、並列に束ねた複数本の線材の一体化と同時に、摩擦増加剤を固定してもよい。   In addition, a friction increasing agent is mixed in advance with a thermoplastic resin powder that fixes a plurality of wires bundled in parallel, and the friction increasing agent is sprayed with an electrostatic coating apparatus together with the thermoplastic resin powder, The friction increasing agent may be fixed simultaneously with the integration of the plurality of wires bundled in parallel.

上記静電塗装装置としては、コロナ帯電式、摩擦帯電式のいずれの方式のものも使用することができる。   As the electrostatic coating apparatus, any one of a corona charging type and a friction charging type can be used.

上記熱可塑性樹脂の粉体としては、ポリエチレン、ポリプロピレン、塩化ビニルのいずれか、またはこれらの成分を含むものを使用することができる。   As the thermoplastic resin powder, any of polyethylene, polypropylene, vinyl chloride, or those containing these components can be used.

この発明は、以上のように、端部に螺旋状の巻付け部を形成した並列に束ねた複数本の金属製の線材の外表面に、静電塗装装置を使用して熱可塑性樹脂の粉体を静電気的に付着させ、その後、付着した熱可塑性樹脂の粉体を加熱熔融することにより、巻付けグリップを製造するという方法である。   As described above, the present invention uses an electrostatic coating apparatus on the outer surface of a plurality of metal wires that are bundled in parallel and formed with a spirally wound portion at the end portion. In this method, the body is electrostatically attached, and then the attached thermoplastic resin powder is heated and melted to produce a winding grip.

この方法によると、並列に束ねた線材間に熔融した熱可塑性樹脂が浸透し、均一な膜厚で並列に束ねた線材を互いに接合することができる。   According to this method, the molten thermoplastic resin permeates between the wires bundled in parallel, and the wires bundled in parallel with a uniform film thickness can be joined to each other.

そして、この発明の巻付けグリップの製造方法は、溶剤系の接着剤を使用しないので、環境に優しい。また、静電塗装装置を使用するので、熱可塑性樹脂の粉体を巻付けグリップに吹き付けて付着させる際に、付着しなかったオーバースプレー粉を回収して再利用することができるので、材料の無駄が少なく、環境にやさしい。   And since the manufacturing method of the winding grip of this invention does not use a solvent-type adhesive agent, it is environmentally friendly. In addition, since the electrostatic coating device is used, when spraying the thermoplastic resin powder onto the winding grip, the overspray powder that has not adhered can be collected and reused. Less waste and environmentally friendly.

以下、この発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

巻付けグリップ１は、図１に示すように、端部に螺旋状の巻付け部２を形成した複数本の金属製の線材を並列に束ねたものである。   As shown in FIG. 1, the winding grip 1 is formed by bundling a plurality of metal wires in which a spiral winding portion 2 is formed at an end portion in parallel.

巻付けグリップ１を形成する線材は、例えば、線径が１．６φ〜４．２φで、長さが４ｍある。   For example, the wire rod forming the winding grip 1 has a wire diameter of 1.6φ to 4.2φ and a length of 4 m.

この発明の巻付けグリップ１は、並列に束ねた線材の外表面に、静電塗装装置９を使用して熱可塑性樹脂の粉体１０を静電付着させ、その後、熱可塑性樹脂の粉体１０を加熱熔融することにより、並列に束ねた線材を接着一体化したものである。   In the winding grip 1 of the present invention, the thermoplastic resin powder 10 is electrostatically attached to the outer surface of the wires bundled in parallel by using the electrostatic coating apparatus 9, and then the thermoplastic resin powder 10 is used. By heating and melting, the wires bundled in parallel are bonded and integrated.

巻付けグリップ１を形成する線材は、熱可塑性樹脂の粉体１０を付着させる前に、脱脂を行った後に、酸洗槽、亜鉛めっき炉を通過させる。   The wire forming the winding grip 1 is passed through a pickling tank and a galvanizing furnace after being degreased before adhering the powder 10 of the thermoplastic resin.

図４に示す静電塗装装置９は、塗装ブース１１内に、熱可塑性樹脂の粉体１０を散布する静電塗装ガン１２が設置され、塗装ブース１１内を通過する巻付けグリップ１に対して、静電塗装ガン１２から熱可塑性樹脂の粉体１０を散布すると、巻付けグリップ１の外表面に静電気的に熱可塑性樹脂の粉体１０が均一に付着する。   The electrostatic coating apparatus 9 shown in FIG. 4 is provided with an electrostatic coating gun 12 for spraying thermoplastic resin powder 10 in a coating booth 11, and the winding grip 1 that passes through the coating booth 11. When the thermoplastic resin powder 10 is sprayed from the electrostatic coating gun 12, the thermoplastic resin powder 10 is electrostatically uniformly attached to the outer surface of the winding grip 1.

静電塗装ガン１２には、粉体タンク１３から定量供給装置１４を介してインジェクター１５によって粉体１０が供給される。静電塗装ガン１２から噴射された粉体１０の内、巻付けグリップ１に付着しなかったオーバースプレー粉は、塗装ブース１１の底面の回収ダクト１６から集塵機１７に回収される。   The powder 10 is supplied to the electrostatic coating gun 12 by the injector 15 from the powder tank 13 via the quantitative supply device 14. Of the powder 10 sprayed from the electrostatic coating gun 12, the overspray powder that has not adhered to the winding grip 1 is collected by the dust collector 17 from the collection duct 16 on the bottom surface of the painting booth 11.

回収されたオーバースプレー粉は、粉体タンク１３に供給され、新粉１８と混合されて再利用される。   The collected overspray powder is supplied to the powder tank 13, mixed with the new powder 18 and reused.

図４の実施形態では、巻付けグリップ１は、塗装ブース１１の一端から塗装ブース１１内に供給され、塗装ブース１１の他端から引き出されて加熱炉１９に送られる。   In the embodiment of FIG. 4, the winding grip 1 is supplied into the painting booth 11 from one end of the painting booth 11, pulled out from the other end of the painting booth 11, and sent to the heating furnace 19.

加熱炉１９を通過中に、巻付けグリップ１の外表面に付着した熱可塑性樹脂の粉体１０が加熱溶融し、熱可塑性樹脂が並列に束ねた線材間に浸透する。   While passing through the heating furnace 19, the thermoplastic resin powder 10 adhering to the outer surface of the winding grip 1 is heated and melted and penetrates between the wires bundled in parallel.

巻付けグリップ１は、例えば、２００℃の加熱炉１９を２２分で通過するようにすると、並列に束ねた線材間に熱可塑性樹脂がゆっくりと浸透し、加熱炉１９から巻付けグリップ１を取出すと、熱可塑性樹脂が固まって、並列に束ねた線材が互いに接合一体化される。   For example, when the winding grip 1 passes through a heating furnace 19 at 200 ° C. in 22 minutes, the thermoplastic resin slowly permeates between the wires bundled in parallel, and the winding grip 1 is taken out from the heating furnace 19. When the thermoplastic resin hardens, the wires bundled in parallel are joined and integrated.

この後、巻付けグリップ１を回転させながら搬送し、搬送路中に、巻付けグリップ１の螺旋状の巻付け部２の内側に、接着剤８と摩擦増加剤７を順次散布している。   Thereafter, the winding grip 1 is conveyed while being rotated, and the adhesive 8 and the friction increasing agent 7 are sequentially sprayed inside the spiral winding portion 2 of the winding grip 1 in the conveyance path.

巻付けグリップ１の巻付け部２に摩擦増加剤７を付着する方法としては、上記のように、接着剤８を使用する方法以外に、熱可塑性樹脂の粉体１０を加熱溶融する際に、螺旋状の巻付け部２の内側に摩擦増加剤７を散布し、巻付けグリップ１の線材の固定と共に、摩擦増加剤７を接着するという方法、あるいは熱可塑性樹脂の粉体１０に、予め摩擦増加剤７を混合しておき、静電塗装ガン１２によって、熱可塑性樹脂の粉体１０と共に、摩擦増加剤７を巻付けグリップ１に吹き付け、並列に束ねた複数本の線材の一体化と同時に、摩擦増加剤７を固定するようにしてもよい。   As a method of attaching the friction increasing agent 7 to the winding portion 2 of the winding grip 1, as described above, in addition to the method of using the adhesive 8, when the thermoplastic resin powder 10 is heated and melted, The friction increasing agent 7 is sprayed on the inner side of the spiral winding part 2 and the friction increasing agent 7 is adhered together with fixing the wire rod of the winding grip 1 or the powder 10 of the thermoplastic resin is previously rubbed. The increasing agent 7 is mixed, and the friction increasing agent 7 is sprayed onto the winding grip 1 together with the thermoplastic resin powder 10 by the electrostatic coating gun 12, and simultaneously with the integration of a plurality of wires bundled in parallel. The friction increasing agent 7 may be fixed.

熱可塑性樹脂の粉体１０としては、例えば、平均粒度分布が１００μｍのポリエチレン樹脂を使用することができる。一般的に、熱可塑性樹脂は、エポキシやポリエステル等の熱硬化性樹脂に比べて、弾性があるので、曲げ加工が容易で、落下衝撃性に強い。   As the thermoplastic resin powder 10, for example, a polyethylene resin having an average particle size distribution of 100 μm can be used. In general, a thermoplastic resin is more elastic than a thermosetting resin such as epoxy or polyester, so that it can be easily bent and has a strong drop impact.

また、摩擦増加剤７としては、例えば、ＪＩＳ Ｒ ６１１１の「人造研磨材」に規定するアルミナ＃８０や、カーボランダムが使用される。   Further, as the friction increasing agent 7, for example, alumina # 80 or carborundum defined in “Artificial abrasive” of JIS R 6111 is used.

図４に示す実施形態では、塗装ブース１１内を通過する巻付けグリップ１の上下に、各２本の静電塗装ガン１２を設置している。   In the embodiment shown in FIG. 4, two electrostatic coating guns 12 are installed above and below the winding grip 1 passing through the coating booth 11.

静電塗装ガン１２としては、コロナ帯電式または摩擦帯電式のものを使用することができる。   As the electrostatic coating gun 12, a corona charging type or a friction charging type can be used.

コロナ帯電式の静電塗装ガンは、ガン先に配置されたコロナ電極からのコロナ放電により、塗装対象の被塗装物との間で電場を形成し、この電場によって熱可塑性樹脂の粉体１０に電荷を帯びさせて、熱可塑性樹脂の粉体１０を被塗装物に対して静電気力で付着させるものである。   The corona charging type electrostatic coating gun forms an electric field with the object to be coated by corona discharge from a corona electrode arranged at the tip of the gun, and the electric field forms a thermoplastic resin powder 10. The thermoplastic resin powder 10 is made to adhere to the object to be coated with electrostatic force by being charged.

一方、摩擦帯電式の静電塗装ガンは、例えば、４フッ化エチレン等の非導電性樹脂チューブを備え、この非導電性樹脂チューブ内を、熱可塑性樹脂の粉体１０を通過させることにより、熱可塑性樹脂の粉体１０に、摩擦帯電によって電荷を与えるものであり、帯電量は、一般的にはコロナ帯電式のものよりも２〜４倍多い。   On the other hand, the triboelectric electrostatic gun is equipped with a non-conductive resin tube such as tetrafluoroethylene, and by passing the thermoplastic resin powder 10 through the non-conductive resin tube, A charge is imparted to the thermoplastic resin powder 10 by frictional charging, and the amount of charge is generally 2 to 4 times that of the corona charging type.

このため、摩擦帯電式の静電塗装ガンは、コロナ帯電式のように電場によって被塗装物に粉体１０を付着させるものではなく、粉体１０自体が持っている電荷によって被塗装物に付着するため、凹部への入り込みが良好であるので、巻線グリップ１の螺旋状の巻付け部２の内側や、並列する線材間の隙間に熱可塑性樹脂の粉体１０が良好に付着する。   For this reason, the friction charging type electrostatic coating gun does not attach the powder 10 to the object to be coated by an electric field like the corona charging type, but adheres to the object to be coated by the electric charge of the powder 10 itself. Therefore, since the penetration into the concave portion is good, the thermoplastic resin powder 10 adheres well to the inside of the spirally wound portion 2 of the winding grip 1 and the gap between the parallel wire members.

上記図４に示す実施形態は、塗装ブース１１内を巻線グリップ１を通過させ、通過中に静電塗装ガン１２によって熱可塑性樹脂の粉体１０を付着させるものであるが、図５に示す実施形態は、塗装ブース１１内に巻線グリップ１を収容し、巻線グリップ１に対して静電塗装ガン１２を移動させるようにしたものである。   In the embodiment shown in FIG. 4, the winding grip 1 is passed through the coating booth 11, and the thermoplastic resin powder 10 is adhered by the electrostatic coating gun 12 during the passage, as shown in FIG. 5. In the embodiment, the winding grip 1 is accommodated in the coating booth 11 and the electrostatic coating gun 12 is moved with respect to the winding grip 1.

また、図６に示す実施形態は、小型の塗装ブース１１を使用し、塗装ブース１１自体を巻線グリップ１に対して移動させるようにしたものである。   In the embodiment shown in FIG. 6, a small painting booth 11 is used and the painting booth 11 itself is moved with respect to the winding grip 1.
