Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and an apparatus for laminating one sheet glass of laminated glass with another sheet glass via an interlayer film.

(Prior art) Laminated glass used as automobile front windshields, etc., is produced by overlaying an interlayer film such as polyvinyl butyral on the top surface of one of the glass sheets constituting the laminated glass, and bonding two sheets of glass through this interlayer film. It is manufactured by doing.

As a device for overlapping two sheets of glass with an interlayer film interposed between them, Japanese Patent Laid-Open No. 58-26053 and Japanese Patent Laid-Open No.
The one disclosed in No. 62-202843 is known.

The device disclosed in Japanese Patent Application Laid-open No. 58-26053 transports two sheets of glass that have been molded and are still at a high temperature by stacking them on a conveyor with their concave surfaces facing upward, After positioning,
Lift up the upper glass plate, then insert the mold holding the interlayer film by suction between the two glass plates, and place the interlayer film on the upper surface of the lower glass plate.
The interlayer film placed on the plate glass is made to adhere to the upper surface of the plate glass by the heat of the plate glass.

On the other hand, the device disclosed in Japanese Patent Application Laid-Open No. 62-202843 separates two glass plates without overlapping them and transports them on a conveyor, and after positioning the two glass plates at different locations, one of the glass plates is separated and transported on a conveyor. An interlayer film is placed on the top surface of the glass plate, and then the two glass plates are stacked on top of each other.

(Problems to be Solved by the Invention) In the conventional methods and devices described above, after positioning the glass plates, an interlayer film is placed on the upper surface of one of the glass plates, and then the two glass plates are combined. As a result, other operations (processes) are involved after positioning, and two sheets of glass may be overlapped with a misalignment.
Furthermore, since the positioning of the glass plate and the placement of the interlayer film are performed at the same station, the cycle time becomes longer.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a transport device that transports two sheets of glass as laminated glass as a pair, and an elevator that transfers the glass sheets between this transport device. A device, a movable frame supported by the elevating device that allows one glass plate to face above the other glass plate, and an interlayer film that simultaneously positions the two glass plates and protrudes from the periphery of the upper surface of one of the glass plates. The overlapping device was constructed by a positioning device equipped with an air nozzle that blows up the peripheral edge of the sheet.

(Function) An interlayer film is placed on the upper surface of one of the glass plates while the pair of glass plates are being conveyed along the glass conveyance line, and then the pair of glass plates are conveyed downstream, and an interlayer film is placed above one of the glass plates on the other side. The glass plates are faced, and then the two glass plates are simultaneously positioned and overlapped.

Thereafter, the suction of the side edge of the interlayer film 3 by the suction pad 107 is released, and the interlayer film 3 is allowed to fall onto the glass plate G1. Here, without releasing the suction state for the center of the interlayer film, the suction pad 107 is lowered as shown in FIG. 11 to press the center of the interlayer film 3 against the center of the glass plate G1. At this time, a portion slightly outside the center of the interlayer film 3 is covered with wrinkle smoothing bars 110 and 1.
It hangs on 10.

Then, while pressing the center of the interlayer film 3 against the glass plate G1, the timing belt 108 is run to move the pair of wrinkle smoothing bars 110, 110 in a direction away from each other as shown in FIG. 12, that is, from the center of the glass plate to the outside. Make it move. Then, the interlayer film is gradually placed on the upper surface of the glass plate G1 from the center without entrapping air or causing wrinkles.

Thereafter, as shown in FIG. 13, the pad 107 adsorbing the center part of the interlayer film 3 is released and raised, and then the cylinder unit 11

(Effects of the Invention) As explained above, according to the present invention, since the positioning of the glass plate is performed after placing the interlayer film on one of the glass plates constituting the laminated glass, the two glass plates may be misaligned. There is no overlap, and the placement of the interlayer film and the positioning of the plate glass are performed at different stations, so the cycle time can be shortened. Furthermore, when positioning the glass plate, the peripheral edge of the interlayer film protruding from the periphery of the glass plate is blown up to prevent the interlayer film from being caught between the glass plate and the positioning pushers or rollers. Even if the plate glass is positioned after being placed on the plate glass, no problem occurs.
