[0006]

In the manufacture of laminated glass for vehicles, visual inspection after washing and drying of the base glass and insertion of an intermediate film between two glass plates are performed in a clean room. The glass plates are loaded one by one into a visual inspection position in a clean room in a horizontal posture in order of a large (outside) glass plate and a small (inside) glass plate, with the convex surface facing upward. It is transferred onto the glass supporting fixed frame from the transport frame.

The curved glass plate on the glass supporting fixed frame is taken up by the raising and lowering means by the glass supporting frame in a horizontal state and is raised, and the pressing member of the pressing means presses the edge on one side of the glass plate. Then, the curved glass plate is slid to the stopper position at the other end, and the curved glass plate is sandwiched between the pressing member and the stopper. Next, while holding the curved glass plate, the glass support frame is turned by 90 ° by turning means so that the stopper side on the glass support frame faces the inspector, and simultaneously with the turning operation, or for a short time. The glass support frame is moved up and down by the lifting means with a delay. After the completion of raising and lowering, the pressing member is retracted.

After the inspection is completed, the curved glass plate is transferred from the receiving member to the glass supporting fixed frame by the raising / lowering means, the turning means, and the elevating means, and then is carried out. Since the curved glass plate is shifted to the downstream side by the amount of movement of the glass on the glass support frame with respect to the transport direction by the pressing unit, the shift amount can be corrected by the position correction unit if necessary in a subsequent process. .

The receiving member, the stopper, and the pressing member fixed on the glass supporting frame are made of a material that is easy to slide and generates little abrasion dust, so that the glass surface can be prevented from being contaminated by dust and can be pressed. Since the turning operation is performed while the glass plate is held by the means, the glass plate does not shift or be damaged during the turning operation, and the glass plate slides during the raising / lowering operation and the glass plate is brought into contact with the stopper. The occurrence of defective products can be prevented without damaging the edges, and the tact time can be increased.
