BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass plate draining device capable of following a flat glass plate with one kind of slit to a curved glass plate having various curvatures.

[0002]

2. Description of the Related Art A laminated glass such as a windshield of an automobile is made by bending a glass plate and sandwiching a plastic film in the middle to adhere the glass plate. At this time, the curved glass plate is thoroughly washed. It must be cleaned, and in such work processes, it is usually dry brush cleaning, water cleaning by spraying cleaning water, draining by using a sponge roll or blowing gas, and transfer to the next combining process while passing through each process. , Is what is processed.

Further, in recent years, glass products in which various functional thin films are coated on the surface of each glass plate for vehicles, buildings, etc. by a sputtering apparatus have become popular. In this case, the glass products of the glass plate in a vacuum chamber are used. In order to attach metal particles to the surface, the water-drying process is necessary as a process of thoroughly cleaning the glass plate surface for dirt and deposits in this pretreatment process and removing water droplets during cleaning by blowing gas or the like. It was

As a conventional apparatus for draining and drying a curved glass plate, for example, in Japanese Patent Publication No. 62-49117, a pair of flat portion sponge rolls that come into contact with the flat portions of the upper and lower surfaces of the glass plate to be transferred, There is described a draining device comprising a pair of sponge rolls for a bending portion, which is provided with an angle adjusting mechanism that comes into contact with a bending portion and changes an inclined posture according to the curved shape of the bending portion, and JP-A-3-12279. Is an air knife that has a member that is a pattern that traverses the moving direction of a glass sheet that is transported on a transport conveyor mechanism and that is formed of a flexible tube with respect to at least one wide surface of the sheet and that defines an elongated groove. And a mechanism for adjusting the shape of the glass sheet according to the curved shape of the glass sheet.

[0005] Further, the applicant's actual fairness 4-153
According to Japanese Patent Laid-Open No. 50, a rotatable outer cylinder and an inner cylinder that connects between the gas introductions are arranged at the upper and lower positions facing the curved glass plate surface to be conveyed, and the outer cylinder has a curvature in the axial direction. Disclosed is a washing and draining device for a curved glass plate, in which two or more nozzles having different slit-shaped openings are erected upright so that any one nozzle of the outer cylinder communicates with the inner cylinder.

[0006]

Cleaning of the glass plate surface,
If the draining process is not sufficient and dirt, water drops, etc. are attached to the surface of the glass plate, defects such as pinholes will occur on the surface of the glass plate that has been sputtered, and defects such as uneven filming will occur. In order to sufficiently remove water droplets, it was necessary to perform draining using a slit matched to the shape of the glass plate surface.

Since the one disclosed in Japanese Patent Publication No. 62-49117 uses a sponge roll, it can respond to a change in curvature to some extent by deformation caused by pressing against the curved shape of the glass plate, but the pressing pressure on the glass plate surface is constant. Therefore, there was a problem that it could not be surely drained, and that the sponge deteriorated due to use over the years and the sponge fragments or dust attached to the sponge adhered to the glass plate surface. .

Further, the one disclosed in Japanese Patent Laid-Open No. 3-12279 is made of a flexible tubing which is flexible and conforms to a flat glass sheet suitable for a windshield glass plate of an automobile. It can be adjusted along the longitudinal direction to a linear arrangement and a predetermined curvature that adapts to the curved shape of the glass sheet, and the adjustment to the curved shape and the gap with the glass plate surface only by the position and angle of the rod. However, there is a problem in that it takes a lot of labor and time to make a severe adjustment.

Further, in the one disclosed in Japanese Utility Model Publication No. 4-15350, two or more nozzles having slit-shaped openings having different curvatures in the axial direction are erected on the outer cylinder.
Since any one nozzle of the outer cylinder and the inner cylinder are communicated with each other, it is possible to cope with a curved glass plate that fits a nozzle having a slit-shaped opening attached, but the number of attachments However, there is a limit and it cannot be applied to all shapes.
