DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing a coating layer formed on one surface of a glass plate used for laminated glass of a window of an automobile, double glazing of a window of a general building, and the like. The present invention relates to the apparatus and a glass sheet processing apparatus provided with the apparatus.

[0002]

A laminated glass having a function of blocking heat rays, ultraviolet rays, and the like is a heat ray formed by subjecting one surface of each of two glass plates to sputtering (metal deposition). The coating layers that block ultraviolet rays etc. are directed inward to each other, and between them, pressure, heat, etc. are applied to the two glass plates while sandwiching a polyvinyl butyral sheet,
By bonding the film layer and the polyvinyl butyral sheet,
Is formed. However, since the film layer and the polyvinyl butyral sheet are hard to adhere to each other, their adhesion state is likely to be incomplete, and moisture, air, etc. infiltrate from the incomplete adhesion state around them, and the polyvinyl butyral sheet becomes incomplete. Oxidizes, develops color and changes. Therefore, the glass layer and the polyvinyl butyral sheet, which easily adhere to each other, are adhered to each other by removing the film layer around the periphery. Further, a double-glazed glass having a function of blocking heat rays, ultraviolet rays, and the like, the coating layers formed on one surface of each of the two glass plates are inwardly directed to each other, so that the space therebetween is sealed. Adhesive elastic body consisting of butyl and thiochol (hereinafter referred to as butyl rubber)
Are formed by bonding the spacers. However, since the coating layer and the butyl rubber are difficult to adhere to each other, their adhesion state is likely to be incomplete, and moisture or the like can penetrate from a part where the adhesion state is incomplete and the sealed state cannot be maintained. The heat insulating effect of the glass is significantly reduced, and water droplets and the like are generated on the coating layer. Therefore, the glass layer and the butyl rubber, which are easily adhered to each other, are adhered to each other by removing the film layer in the periphery.

[0003] Conventionally, the outer surface of an annular grindstone is brought into contact with a film layer around a glass plate, and this grindstone is rotated and the grindstone itself is moved to remove the film layer.

However, in the conventional method of removing the film layer, the direction in which the outer surface moves at the contact portion where the outer surface is in contact with the film layer and the grindstone itself are moved by rotating the grindstone. By doing so, the direction in which the outer surface moves in the abutting portion is set to be on the same line, so if a scratch or the like occurs on the outer surface,
When the coating layer becomes streaks and tends to remain on the glass plate, and the coating layer is left, adhesion between the glass plate and the polyvinyl butyral sheet or between the glass plate and butyl rubber cannot be completed.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a method in which a film layer becomes a streak when a surface to be removed from which a film layer is removed is damaged.
