JPH09180892A - Static eliminator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a static eliminator which can prevent fall-off of static electricity-eliminating fiber by welding metallic fiber to a single metallic plate, and covering this upper surface with a protective material. SOLUTION: Metallic fiber (for example, stainless fiber) is welded to a single metallic plate (for example, a stainless plate) by solder, tin solder, a laser, an arc, sputtering or the like, and this upper surface is covered with a protective material, and a static eliminator is manufactured. Therefore, the metallic fiber does not fall off, and even when it curves, since it is a single metallic plate, dislocation such as damaging the metallic fiber is not caused, and the static eliminator having stable quality can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in the field of removing static electricity from an object having static electricity.

[0002]

2. Description of the Related Art A conventional static eliminator is a product in which static elimination fibers (fibers having a static elimination effect) and an adhesive are put between two metal plates and pressed from the outer surface of the metal plates and dried. With this method, a gap is created between the metal plate and the thickness of the static elimination fiber. Most of the adhesive enters here, and it is difficult for the static elimination fiber to permeate into the interior of the static elimination fiber. Therefore, the adhesion of the static elimination fiber becomes insufficient and the static elimination fiber falls off. Further, when attached in a curved shape, the two metal plates are displaced and the static elimination fiber is damaged, peeled off and separated from the metal plate.

When the static elimination fibers fall out in this way, they enter the high-voltage charging section of the OA machine (which indicates a copying machine, a printer, a fax machine, etc.) and cause an unexpected accident.

Japanese Patent Publication No. 1-5 for improving the above drawbacks
There is 4839. This is one in which one of the two metal plates is a thin and soft plate, and the antistatic fibers are wrapped in it, the interval between the antistatic fibers is eliminated, and the adhesive is sufficiently penetrated into the antistatic fiber.

[0005]

Even with this method, if the intervals of the static elimination fibers are close, the wrapping effect is not sufficient,
The static elimination fibers fall out. Further, the above method has low productivity and cannot keep up with the recent production amount of OA equipment.

[0006]

An electrostatic eliminator characterized in that a metal fiber is welded to one metal plate and a protective material is coated on the metal fiber.

[0007]

[Function] Since the metal fibers are welded (solder, silver brazing, laser, arc, spatter, etc.) to one metal plate, the metal fibers do not fall off and one metal plate can be used even when curved. Therefore, it does not cause a displacement that damages the metal fiber. Therefore, there is no failure due to the dropping of the metal fibers of the OA equipment, and the process is further simplified and automation becomes possible.

[0008]

EXAMPLE A stainless steel plate having a thickness of 0.3 mm, a width of 10 mm and a length of 500 mm was used, and 12 μm * 100 stainless steel fibers were used as metal fibers, and laser welding was performed at a fiber interval of 0.5 mm. An electrostatic remover of the present invention was made. This was processed so as to be attached to the Xerox Able 3200, mounted, and tested for one year.

As a result, in the examples, there was no failure of the OA equipment due to the dropping of the metal fibers, and no damage to the metal fibers was observed even in the bending deformation of 50 mm or less.

On the other hand, in the case of the commercially available product, the OA device once failed due to the removal of the static elimination fibers. Further, in the bending deformation of 50 mm or less, the static elimination fiber was damaged.

[0011]

INDUSTRIAL APPLICABILITY The static eliminator of the present invention does not drop fibers regardless of how it is used.
Equipment A does not break down. Also, since the process is simplified, automation is possible, stable product purchase and mass production are possible.
