Abstract

PURPOSE:To place a wrinkleless thin film sheet such as interlayer on the top of flat glass by receiving the thin film sheet sent to the top of flat glass on the top of the flat glass and moving a wrinkle smoothing lever from the center of the flat glass to the outside. CONSTITUTION:Flat glass G1, G2 transported with laying an uneven face on the top is placed below a wrinkle smoothing lever 110 and located. Then a thin film sheet 3 such as interlayer sent by a conveyor to the top of one flat glass is dropped in such a way that the sheet is partially hung on the lever 110. Then the lever 110 is transferred from the center along the flat glass G1 or G2 so that the sheet 3 is laid on the top of the flat glass G1 or G2 without producing wrinkles. In the above-mentioned method, since an adsorbing mold is not used in placing the thin film sheet on the top of the flat glass, this method is used as it is even if the shape of the thin film sheet is changed by alternation of kinds of machines and has extremely excellent general purpose. The thin film sheet can be surely placed on the top of the flat glass without rolling air on the glass.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and an apparatus for transferring an interlayer film (thin film sheet) onto the upper surface of one glass plate constituting a laminated glass, for example.

(Prior art) Laminated glass used as front windshield glass for automobiles, etc., is made by layering an interlayer film such as polyvinyl butyral on the top surface of one of the glass sheets making up the laminated glass, and bonding the two sheets of glass through this interlayer film. It is manufactured by doing.

A known device for placing an interlayer film on the upper surface of a glass plate is disclosed in Japanese Unexamined Patent Publication No. 58-26053.

This device transports two sheets of glass, which have been formed and are still hot, stacked on a conveyor with the concave side facing upward. After positioning the two sheets of glass that have been conveyed, the upper sheet of glass is lifted, and then the middle The mold that holds the film by adsorption is inserted between two glass plates, and the interlayer film is placed on the upper surface of the lower glass plate, and the heat of the glass plate causes the placed interlayer film to stick to the upper surface of the glass plate. It is something.

(Problem to be solved by the invention) The conventional transfer device described above requires a mold to adsorb and hold the interlayer film, and a new mold must be manufactured each time the model is changed. It won't happen. In addition, in order to prevent the placed interlayer film from shifting on the top surface of the glass plate, it is necessary to transfer the interlayer film when the temperature of the glass plate is high, making timing difficult. Wrinkles tend to form on the interlayer film due to the mounting.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a transport device that transports a thin film sheet such as an interlayer film to the top surface of a plate glass, and a transport device that transports a thin film sheet, such as an interlayer film, to the top surface of a plate glass. A wrinkle smoothing bar for placing the thin film sheet on the upper surface without wrinkles was incorporated as part of the transfer device.

(Function) The plate glass that has been conveyed with the convex surface as the upper surface is positioned below the wrinkle removing bar, and the thin film sheet that has been carried by the conveying device falls onto the top surface of this plate glass, and a part of the thin film sheet is placed under the wrinkle removing bar. It takes. Thereafter, the wrinkle-smoothing bar moves outward along the glass sheet, so that the thin film sheet is stacked on the top surface of the glass sheet without wrinkles.
