Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used, for example, as a paper feed roll of electronic copying machines and facsimile machines, a cleaning roll of drums, a paper feed roll of cash registers, a cleaning brush of various OA equipment, etc. The present invention relates to a method of manufacturing a charge removing tool used.

[Conventional technology]

Conventionally, this type of charge removing tool has been developed by wrapping a double-sided tape tape having a conductive adhesive layer around the outer periphery of a conductive core material α0 shown in FIG. 1) was manufactured by winding it around as shown in FIG.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional manufacturing method is extremely time-consuming, has shape limitations, and requires a raised blanket (1
) is expensive, the pile density of the raised blanket (1) is uneven, and gaps are likely to occur between the wrapped raised blankets (1).

[Means for solving problems]

The present invention, as a means to solve the above-mentioned conventional problems, comprises applying a conductive adhesive to the surface of a conductive base material (1), and further comprising an insulator and a conductor (108).
The present invention provides a method for manufacturing a charge removing tool, which is characterized by flocking conductive composite fibers having a leakage resistance of Ω or less in an electrostatic field.

[For production]

The effects of the present invention are as follows.

Is the surface of the substrate conductive? Guide 1! When a pile of conductive composite fibers is spread over the adhesive by applying an electrostatic field, the axial direction of the pile is perpendicular to the flocked surface due to the electrostatic field. The conductive adhesive is then applied to form a flocked layer. like this? When the thus formed flocked layer is touched by a charged object, the charge in the charged object escapes from the flocked layer to the base material side via the adhesive layer.

〔Effect of the invention〕

Therefore, in the present invention, the charge removing tool can be manufactured in any shape very easily and at low cost, and can be manufactured on the surface of the base material. This uniform flocked layer is formed, and since the flocked layer is made of conductive composite fibers having a leakage resistance of 10Ω or less, the effect of removing static electricity from charged objects is extremely high.

〔Example〕

The present invention will now be described as an embodiment shown in FIGS. 1 to 4. The base material (1) shown in FIG. 1 is a round bar made of a conductive material such as carbon or metal; Surface t of the base material [1)
This is a synthetic resin adhesive such as acrylic resin, epoxy resin, urethane resin, or polyester resin.A conductive adhesive mixed with a conductive filler such as carbon powder or metal powder is applied, as shown in Figure 2. A coating layer (2) is formed. When the base material α) on which the coating layer (2) has been formed is subjected to an electrostatic field i and the conductive composite fiber pile (3) is spread, the pie/
L/(8) is oriented perpendicularly to the flocked surface, that is, the surface of the coating layer (2), and pierces the surface of the coating layer (2). After transplanting Pi/L/(8), heat drying, curing, etc. are performed if desired. Pi/L/(8) of the conductive composite fiber
These are conventional synthetic fiber materials such as polyester, polyamide, polyacrylonitrile, and polyvinylidene chloride, polymer materials, insulators that give gold to inorganic materials such as glass, and ceramics, and carbon.

A fiber made of a composite of a conductor such as a metal, for example, a pile of composite fibers in which a conductive component made of the above-mentioned conductor is distributed inside the insulating fiber made of the above-mentioned insulator, etc. 1) Composite fiber obtained by dispersing and spinning the conductor powder, or a composite fiber coated with a paint mixed with conductor powder on the R fiber surface of the insulator;
Further examples include composite fibers in which the fiber surface of the insulator is coated with metal by plating, vapor deposition, sputtering, etc. The above examples are not intended to limit the invention.

The composite fiber should have a leakage resistance of 10 Ω or less in order to obtain the desired static electricity removal effect. Further? Preferably, the leakage resistance is 10 6 to 10 8 Ω. If the leakage resistance is less than 10Ω, flocking is unstable or a short circuit is likely to occur.

Also, if you have 108 views or more, what should you do as mentioned above? In addition to this, the static electricity removal effect is reduced, and the flying ability during hair transplantation is poor.

As shown in FIG. 4, conductive fibers (8)B are exposed at the upper and lower ends of the charge removing tool (4) manufactured according to the present invention. , the conductive fiber (8)B directly contacts the conductive adhesive layer [2] at the lower end t of the pie 1v (8). Therefore, as shown in Fig. 5, a pair of charge removing tools (4)A, (4)Bt
It can be used as a paper feed roll for electronic copying machines or cash registers, etc., or it can be used as a cleaning roll by contacting the surface of the drum (6) of an electronic copying machine as shown in Figure 6. .

In the case shown in FIG.
) and equipment, etc.? The charged paper (5) is held between a pair of charge removing tools (4)A, r4)Br, and the rolls are rotated in the direction of arrow A.
As a result, when the paper (5) is fed one direction in the direction of the arrow, the charge on the paper (5) is removed by the charge remover (4)A, (4>Bt), and the paper (5) wraps around the charge remover (4)A/). Problems like this will be resolved. In the case shown in FIG. 6, toner is attached to the drum (6) having an electric latent image on its surface, and the toner is transferred to the paper. The charge removal tool (4) is brought into contact with the surface of the drum (6) to erase the electrical latent image and to clean the remaining toner, again preparing for the next copy.

In cases other than the above embodiments, for example, the charge removing tool (4) is only used at the tip of the handle-shaped base material rx> as shown in FIG. The conductive composite fiber pie/
L/(8) may be brush-shaped with flocked hair, and the base material (1) may have an appropriate shape of a flat plate. The flocked layer does not necessarily have to be formed completely.
It may be formed into a predetermined shape such as a striped shape or a pattern.
