JP5506419B2 - Static elimination brush - Google Patents

Description

The present invention is a static eliminator used for removing static electricity from the body of electrical / electronic equipment such as OA equipment (printers, copiers, facsimiles, etc.), ATMs, ticket issuing machines, CD / DVD drives, plastic film manufacturing machines, etc. Regarding brushes.

For electrical and electronic equipment such as office automation equipment, ATMs, ticketing machines, CD / DVD drives, and various plastic processing equipment, a self-discharge type static elimination brush is provided to remove the charging of paper or synthetic resin film as an output medium. It is done.
And as a static elimination brush, the thing of the form formed by pinching and hold | maintaining many arranged fibrous electrodes with an electroconductive adhesive tape is known.

  However, these static elimination brushes have a holding power that is softened and deteriorated when the adhesive or adhesive of the conductive adhesive tape holding the fibrous electrode is used under high temperature environment or in an environment where organic solvent vapor is generated. There was a problem that the fibrous electrode dropped off.

  Therefore, for example, a large number of fibrous electrodes protrude from both side ends parallel to the longitudinal direction of the support plate, and the fibrous electrodes are sandwiched between the support plate and the conductive adhesive tape, and the conductive adhesive tape is placed inside. A neutralizing brush (Patent Document 1) folded in half along the longitudinal direction and a large number of fibrous electrodes protruding from the conductive adhesive tape, and the fibrous electrodes being arranged with the conductive adhesive tape and the linear core There has been proposed a static elimination brush (Patent Document 2) that is sandwiched between two materials and folded in half so that the linear core material is on the inside.

However, even with the conventional static eliminating brushes having these forms, the adhesive or adhesive of the conductive adhesive tape holding the fibrous electrode is softened when used in a high temperature environment or an environment where organic solvent vapor is generated. In addition, it has been insufficient to prevent the problem that the fibrous electrode is lost due to deterioration and loss of holding power.
Therefore, an object of the present invention is to provide a neutralizing brush that can sufficiently exhibit the neutralizing performance with less dropping of the fibrous electrode.

The object of the present invention is achieved by providing a static elimination brush having the following configuration. That is,
(1) The neutralizing brush of the present invention fixes the fibrous electrode folded in half between the holding member and the support member, and the tip end portion of the fibrous electrode protrudes from the holding member and the support member.

  Further, as the electrode substrate 2 (12) of the holding member 5 (15), for example, a metal foil such as an aluminum foil, a synthetic resin film or sheet such as a polyester film, polyethylene or polyurethane, paper, or a laminate thereof. Also good. When the holding member 5 (15) is configured by combining the electrode substrate 2 (12) and the core material 4 (14), a tape-like electrode substrate provided with an adhesive layer on a metal foil is employed. Is preferable from the viewpoint of fixing the fibrous electrode 6 (16).

The core member 4 (14) of the holding member is preferably made of a material such as an aluminum plate, a stainless plate, or a polyester resin plate, which has higher rigidity than the electrode substrate 2 (12).

  The fibrous electrode 6 (16) of the present invention supports the fibrous electrode 6 (16) folded in half as shown in FIGS. 2B, 3 and 4 and the holding member 5 (15). The tip of the fibrous electrode 6 (16) protrudes from the holding member 5 (15) and the support member 7 (17) while being fixed between the members 7 (17). For example, as shown in FIGS. 3D and 4D, the tip end portion of the fibrous electrode 6 (16) protrudes from the tip end portion C of the support member 7 (17).

Examples of the fibrous electrode 6 (16) include metal fibers such as stainless steel fibers, copper, and amorphous alloys, carbon fibers, conductive fibers in which a synthetic polymer is coated with a conductive polymer or copper sulfide, metal dyed fibers, and the like.
