Abstract

PROBLEM TO BE SOLVED: To eliminate static electricity of wire. SOLUTION: The eliminating method for static electricity of wire is constituted so that wire 1 charged with static electricity with positive or negative polarity is run through a closed space 2 extending relatively long in the longitudinal direction, and positively and negatively ionized air is sent around the wire 1 to come into contact with the wire, thus the static electricity with which the wire 1 is charged and has positive or negative polarity is electrically neutralized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for removing static electricity from a wire.

[0002]

2. Description of the Related Art A wire made of a metal material such as copper or aluminum, or a wire made of a glass material such as an optical fiber, is brought into contact with a guide pulley or the like in the working process or with other atmosphere materials. It is common to charge positive or negative static electricity.

Whether the material is charged positively or negatively depends mainly on the material of the wire. In any case, the charging makes it easy for the surrounding fine dust to adhere to the surface of the wire. This is a serious obstacle in the process of forming a film or coating.

[0004]

Various measures have conventionally been taken to remove this static electricity. For example, grounding the guide pulley to release the static electricity, or reducing the chance of electrification by setting the traveling place of the wire as a clean dust-free room, all of which were indirect methods. I can not get the effect,
There has been a demand for measures that have a decisive effect.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. According to the first aspect of the present invention, there is provided a wire having a positive or negative polarity and charged with static electricity. While traveling in a closed space that extends relatively long in the longitudinal direction thereof, sends positively and negatively ionized air around the wire and makes it contact therewith, whereby the positive or negative This is a method for removing static electricity from a wire, characterized by electrically neutralizing static electricity having negative polarity.

A solution according to the second aspect of the present invention is to provide a static electricity removing cylinder having a hollow cylindrical shape having open ends at both ends for running a wire rod, and a discharge box in which two electrodes having different polarities are arranged to face each other. The wire static electricity removing device includes a compressor that supplies compressed air to the discharge box and an ion inflow pipe that connects the static electricity removing cylinder and the discharge box.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 2 denotes an elongated hollow columnar static electricity removing cylinder, which is open at both ends, and through which a wire 1 from which static electricity is to be removed runs.

Reference numeral 3 designates a substantially closed hollow discharge box, in which two electrodes 4A and 4B having opposite polarities are opposed to each other, and when both are supplied with power from a high-voltage high-voltage power supply 5, both of them are disposed. And the air inside is ionized.

[0009] The discharge box 3 is piped so as to be supplied with compressed air from the compressor 6, and is always supplied with fresh compressed air during operation. This discharge box 3
And the inside of the static electricity removing cylinder 2 are connected by an ion inflow pipe 31.

Next, the operation of the device of the present invention will be described. This working step is the method of the present invention. The power supply from the high voltage power supply 5 causes a high voltage discharge between the electrodes 4A and 4B, and as a result, the air in the discharge box 3 is ionized. This situation is shown diagrammatically in FIG. 2, i.e., the internal air molecules are separated into positive ions of positive polarity and negative ions thereof.

Further, since the compressed air is constantly supplied from the compressor 6, the amount of air in the discharge box 3, that is, the number of ions is extremely increased.

The ions of the positive or negative polarity ionized as described above enter the static electricity removing cylinder 2 through the ion inflow pipe 31 and come into contact with the wire 1 traveling here. As a result,-ions act on the positively charged portion of the wire to neutralize it electrically, and + ions act on the negatively charged portion to electrically neutralize it. Neutralize. In this way, all the positive and negative static electricity carried by the wire 1 is eliminated.

[0013]

As is apparent from the above description, according to the present invention, the positive or negative static electricity of the wire can be efficiently removed by the positively and negatively separated ions of the air. effective. Moreover, according to the method of the present invention, since only air contacts the wire, there is an advantage that the wire is not adversely affected at all.
