を提供する。
【００１４】
【実施例】
この発明の実施例をあらわす図１〜図８にしたがって説明する。
【００１５】
１１は、離型シートである。離型シート１１は、可撓性を有し、少なくとも一方の面に離型性を有するものであればればよく、一般的に離型シートとして用いられる例えばシリコーンコーティング紙、ポリオレフィン樹脂コーティング紙等の離型紙、非粘着性樹脂シート、離型処理された合成樹脂シート等が用いられる。この実施例においては、離型シート１１として離型紙を用いた。
【００１６】
１２は、支持材であり帯状からなる。支持材１２は、アルミニウム箔、銅箔等の金属箔、アルミニウム、鉄、ステンレス、銅、リン青銅等の金属板、ポリ塩化ビニル、ポリエステル等の合成樹脂シート、金属箔と合成樹脂のラミネートシート、金属蒸着合成樹脂シート、布帛、紙等からなり、必ずしも導電性を有さなくともよい。支持材１２は、静電気除去装置の基部となるものであり、導電性繊維束２２が固定されればよく、幅としては３ｍｍ〜１０ｍｍ程度が適当である。機器に貼着して使用する静電気除去装置は、支持材１２として片面粘着テープ、両面粘着テープが好ましく用いられる。図５に図示される静電気除去装置の支持材１２は、アルミニウム箔を基材とし、その片面全面に接着剤１３が付けられた片面粘着テープである。接着剤１３は、片面粘着テープの如く支持材１２に付けられたものに限らず、支持材１２を離型シート１１に取り付け可能なものであればよく、離型シート１１あるいは支持材１２の全面もしくは一部に使用するものでもよい。その接着剤１３としては例えばアクリル系、ゴム系、シリコン系、ウレタン系等の感圧型接着剤等が用いられる。また、接着剤１３として、一般的な両面粘着テープも用いられる。図６に図示された静電気除去装置は、支持材１２としてアルミニウム板を用い、接着剤１３として両面粘着テープを用いたものである。
【００１７】
２１はドラムである。ドラム２１は、回転可能でその周面に離型シート１１が取り付け可能であれば形状は問わず、円筒形、多角柱筒でよい。ドラム２１は、木製、金属製あるいはプラスチックス等材質は問わない。ドラム２１は単なるロール状でも、対向させて離して設置させた２個の円盤の周に沿って周相互間を複数の板状体で連結させてほぼ円筒状としてもよい。
【００１８】
まず、ドラム２１周面に、離型シート１１を取り付けるとともに、離型シート表面に複数本の支持材１２を間隔を開けて取り付ける工程は、離型面に複数本の支持材１２が平行に間隔（Ｗ）を開けて接着剤１３によって取り付けられた離型シート１１を、ドラム２１周面に、接着剤、両面粘着テープ等により取り外し可能に取り付けられる。その際、支持材１２を表側とし、支持材１２をドラム２１の長手方向にして取り付けて行われる。
【００１９】
また、離型シート１１をドラム２１周面に取り付けて後、離型シート１１の表面に複数本の支持材１２を取り付けてもよい。
【００２０】
次いで、支持材１２の表面に、支持材１２の設置方向（ドラム２１の長手方向）と交差する方向に導電性繊維束２２を巻き付ける。
導電性繊維束２は、一本の直径が５〜５０μｍ程度の導電性繊維を５〜１００００本程度収束させて一本の束にされ、ボビン２３に巻き付けられている。導電性繊維としては、ステンレス繊維、炭素繊維、硫化銅被覆繊維、ポリピロール等にて処理された導電性繊維等の導電性を有する繊維が用いられる。
【００２１】
導電性繊維束２２は、この実施例では支持材１２とほぼ直角方向に巻き付けられる。図１は、その巻き付け状態を示す説明図である。巻き付けは、ドラム２１をその長手方向中心軸１を中心として回転させ、導電性繊維束２２の一端を例えばドラム２１の一端、支持材１２のうちの１個の一端に接着剤等で固定し、ボビン２３から供給される導電性繊維束２２を他端側へ、所定間隔（Ｐ）となるように少しずつずらしていくことで複数の支持材１２の表面に巻き取らせて行う。ボビン２３の位置を少しずつずらしながら巻き取ってもよい。
【００２２】
ボビン２３は、複数個並べて設け一度に複数本の導電性繊維束２２を供給してもよい。その場合は、より細かい間隔で導電性繊維束２２をドラム２１周囲に供給することが可能となる。
【００２３】
ボビン２３から供給される導電性繊維束２２は、繊維束内部に樹脂が浸透固化されたものであっても、また図３に図示されるように、ボビン２３から支持材１２表面に巻き取られる間で、樹脂液３１中を通過させたうえで、導電性繊維束２２を巻き付けてもよい。その場合は、樹脂液３１が導電性繊維束２２の内部に浸透し、固化されることによって、巻取作業中あるいは以降の工程での導電性繊維束２２のほどけ、ばらけを防止すると共に、静電気除去装置の使用時における繊維束内部からの繊維の抜けをより良好に防止することが可能である。樹脂としては、ポリウレタン、ポリビニルアルコール、ポリ酢酸ビニル等の合成樹脂が用いられる。樹脂液３１中を通過した導電性繊維束２２は、ドラム２１に巻き取る前にロール、スクレーバ等の絞液手段によって余分な樹脂液３１を除くことが好ましい。
【００２４】
次いで、支持材１２上に導電性繊維束２２上から、接着剤１４を塗布して導電性繊維束２２を支持材１２に固定する。図２は、接着剤１４が塗布された状態を示す説明図である。接着剤１４の塗布は、支持材１２の幅全面でも、一部に塗布してもよい。接着剤１４は、導電性繊維束２２内部に浸透し、乾燥固化されて支持材１２に固定される。樹脂で固められた導電性繊維束２２あるいは樹脂液３１を通過させた導電性繊維束２２を用いた場合には、束を被覆する如く塗布され、導電性繊維束２２が支持材１２の表面に固定される。この接着剤１４としては、例えばウレタン系、ゴム系、アクリル系、エポキシ系、ポリオレフィン系等の溶剤系や熱可塑系あるいは熱硬化系等の接着剤が使用できる。導電性接着剤も用いられる。
【００２５】
また、予め表面に接着剤１４が設けられた支持材１２を用いた場合は、導電性繊維束２２上より溶剤塗布、加熱等により接着剤１４の粘接着性を回復させて導電性繊維束２２が固定される。
【００２６】
次いで、図４に図示されるように、接着剤１４が乾燥固化されて後に支持材１２上に位置する導電性繊維束２２、接着剤１４の上から他方の支持材１５を固定する。支持材１５は、片面に接着剤１６が付与されたテープ材が好ましく用いられ、支持材１２と同様の素材を使用することが可能である。接着剤１６は、接着剤１３と同様な接着剤が用いられ、一般的な両面粘着テープも用いることができる。また、接着剤１６を支持材１５あるいは固化した接着剤１４上に塗布して支持材１５を固定しても、表面側に離型紙が付いた両面粘着テープを支持材１５としてもよい。
【００２７】
支持材１５の固定は、ドラム２１に離型シート１１、導電性繊維束２２が巻かれた状態で行っても、ドラム２１から取り外してから行ってもよい。
【００２８】
次いで、導電性繊維束２２を離型シート１１と共に、それぞれの支持材１２（支持材１５）の一方の側縁付近（Ａ又はＢ）長手方向に切断する。すると、図５、図６に示されるように、支持材１２および支持材１５で挟持された導電性繊維束２２を突設させる静電気除去装置が得られる。静電気除去が必要な機器に取り付ける場合は、支持材１２の裏面に取り付けられた離型シート１１を剥がす。すると、離型シート１１に接着していた接着剤１３が剥き出しになり、機器に接着することが可能となる。金属板等に粘着して後に、機器にビス止め等にて取り付けてもよく、接着剤１３も剥がしてビス止め等にて取り付けても良い。
【００２９】
次に、図８に図示されるような、金属板間に導電性繊維束が挟持された構造の静電気除去装置の製造方法を説明する。
【００３０】
図２で図示される支持材１５を固定しない状態から、導電性繊維束２２と離型シート１１を共に、それぞれの支持材１２の一方の側縁付近で長手方向に切断する。ついで、離型シート１１を支持材１２より剥離すると、支持材１２に付けられた接着剤１３が剥ぎ出しになる。そして、断面ほぼＬ字型乃至Ｖ字型に開口してなる開口部内に、切断された導電性繊維束２２を固定させた支持材１２を、支持材１２を奥側に、切断された導電性繊維束２２先端を金属板４１の側縁から露出させて固定させる。固定は、支持材１２の裏面に取り付けられた離型シート１１を剥がし、離型シート１１に接着していた接着剤１３が剥き出しにして、接着剤１３の接着力を利用しておこなう。図７は、固定した状態を示す説明図である。
【００３１】
次いで、金属板４１をプレスする。すると、金属板４１はその内面が近接乃至密接されるように断面Ｕ字型に変形されて、支持材１２、導電性繊維束２２、接着剤１４が挟持され、図８に図示される静電気除去装置が製造される。プレスの際に、アース線を挟持させてもよい。
【００３２】
このようにして製造された静電気除去装置は、その後、取り付け用の穿孔、あるいは切欠加工が施され、また接着剤や両面粘着テープが付与されて、機器に取り付けられて使用される。
【００３３】
また、図２で図示される支持材１５を固定しない状態から、導電性繊維束２２と離型紙１１を支持材１２の一方の側縁付近で長手方向に切断し、離型シート１１を支持材１２より剥離したものを、機器に取り付けて静電気除去装置とすることもできる。
【００３４】
また、図５で図示される静電気除去装置を断面Ｕ字状の金属板に挟持させても良い。
【００３５】
【発明の効果】
したがってこの発明では、静電気除去装置を効率良く生産することが可能である。

[Industrial application fields]
The present invention relates to a method for manufacturing a static eliminator.
[0002]
[Prior art]
Generally, the static eliminator is formed by arranging a large number of conductive fiber bundles as known in JP-A-60-129004 “Brush and manufacturing method thereof” (conventional example).
[0003]
The static eliminator says, “Double-sided adhesive tape is pulled out from the roll along with the release tape and run while the long carbon fiber bundle is pulled out of the roll and cut to a certain length with a cutter. Adhering to the adhesive surface of the sheet, the aluminum foil tape is moved between the pair of pinch rollers while being pulled out of the roll, and bonded to the double-sided adhesive tape that also travels between the pinch rollers. Further, after bending the one side long edge of the bonded aluminum foil tape into a U shape with a molding member, the aluminum foil tape, the double-sided adhesive tape and the release tape which are polymerized and bonded as described above are wound, and the product is wound. Is obtained in a wound state (conventional example).
[0004]
[Problems to be solved by the invention]
However, in the conventional example, the static eliminating device was manufactured by “drawing a long carbon fiber bundle from the roll and cutting it to a certain length with a cutter and simultaneously adhering it to the adhesive surface of the double-sided adhesive tape”. Thus, adhering to the double-sided adhesive tape while cutting the carbon fiber bundle has a problem of poor work efficiency.

[0013]
I will provide a.
[0014]
【Example】
An embodiment of the present invention will be described with reference to FIGS.
[0015]
Reference numeral 11 denotes a release sheet. The release sheet 11 only needs to have flexibility and release properties on at least one surface, and is generally used as a release sheet, such as silicone coated paper, polyolefin resin coated paper, etc. Release paper, non-adhesive resin sheet, release synthetic resin sheet, and the like are used. In this example, release paper was used as the release sheet 11.
[0016]
Reference numeral 12 denotes a support material having a strip shape. The support material 12 is a metal foil such as aluminum foil or copper foil, a metal plate such as aluminum, iron, stainless steel, copper or phosphor bronze, a synthetic resin sheet such as polyvinyl chloride or polyester, a laminate sheet of metal foil and synthetic resin, It consists of a metal vapor deposition synthetic resin sheet, a cloth, paper, etc., and does not necessarily have conductivity. The support material 12 serves as a base of the static eliminator, and it is sufficient that the conductive fiber bundle 22 is fixed. A width of about 3 mm to 10 mm is appropriate. In the static eliminator used by being attached to an apparatus, a single-sided adhesive tape or a double-sided adhesive tape is preferably used as the support material 12. The support member 12 of the static eliminator shown in FIG. 5 is a single-sided adhesive tape having an aluminum foil as a base material and an adhesive 13 attached to the entire surface of one side. The adhesive 13 is not limited to the one attached to the support material 12 such as a single-sided adhesive tape, and any adhesive can be used as long as the support material 12 can be attached to the release sheet 11, and the entire surface of the release sheet 11 or the support material 12. Or you may use for a part. As the adhesive 13, for example, a pressure-sensitive adhesive such as acrylic, rubber, silicon, or urethane is used. Moreover, a general double-sided pressure-sensitive adhesive tape is also used as the adhesive 13. The static eliminator shown in FIG. 6 uses an aluminum plate as the support material 12 and a double-sided adhesive tape as the adhesive 13.
[0017]
21 is a drum. As long as the drum 21 is rotatable and the release sheet 11 can be attached to the peripheral surface thereof, the drum 21 may be cylindrical or polygonal cylinder. The drum 21 may be made of any material such as wood, metal or plastics. The drum 21 may be a simple roll, or may be substantially cylindrical by connecting a plurality of plates along the circumference of two disks disposed opposite to each other.
[0018]
First, the process of attaching the release sheet 11 to the circumferential surface of the drum 21 and attaching the plurality of support members 12 to the release sheet surface with a space therebetween is the step of attaching the plurality of support materials 12 to the release surface in parallel. The release sheet 11 opened with (W) and attached by the adhesive 13 is detachably attached to the peripheral surface of the drum 21 by an adhesive, a double-sided adhesive tape, or the like. At this time, the support member 12 is attached to the front side, and the support member 12 is attached in the longitudinal direction of the drum 21.
[0019]
Further, after the release sheet 11 is attached to the circumferential surface of the drum 21, a plurality of support members 12 may be attached to the surface of the release sheet 11.
[0020]
Next, the conductive fiber bundle 22 is wound around the surface of the support material 12 in a direction crossing the installation direction of the support material 12 (longitudinal direction of the drum 21).
The conductive fiber bundle 2 is made into one bundle by converging about 5 to 10,000 conductive fibers having a diameter of about 5 to 50 μm and wound around the bobbin 23. As the conductive fibers, conductive fibers such as stainless steel fibers, carbon fibers, copper sulfide-coated fibers, conductive fibers treated with polypyrrole, or the like are used.
[0021]
