[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass transfer / positioning device in an automobile glass assembly process.

[0002]

2. Description of the Related Art In a conventional automobile assembly line, when assembling glass into a body, one robot (for one type of glass) first transfers the glass from a drop lifter 2 for supplying glass to a positioning device. Then, the glass positioned here is handled again, an adhesive is applied to the peripheral edge of the glass, and after the application, the glass is handled as it is and attached to the body.

[0003]

However, in the above-described automatic assembly system, since the transfer operation by the robot is large, the cycle time is increased and the line length is increased by securing the transfer space. Therefore, in the light vehicle automated assembly line where the line side space is limited,
There was a problem that it could not be adopted at all.

Therefore, an object of the present invention is to provide a glass transfer / positioning device capable of shortening the cycle time and saving the space of the assembly line.

[0005]

A glass transfer / positioning device according to the present invention comprises a pallet on which glass is placed and conveyed by a conveyor, and a pallet for receiving the pallet from above the conveyor onto an elevator and below the conveyor. A drop lifter that can be lowered to a transfer position, and a plurality of receivers that can vertically pass through the lift and the pallet at a transfer position directly below the elevator and receive glass from the pallet on the elevator and by positioning means. And a positioning device capable of positioning.

It is preferable that the positioning means has a fixed roller that regulates at least one side of the glass and a movable roller that regulates at least the other side of the glass in terms of simplification of the structure.

When a plurality of movable rollers are linked by a link mechanism, the centering of the glass is surely performed and the number of actuators can be reduced, which is preferable.

[0008]

According to the above construction, the glass can be received and positioned from the pallet at the same location, so that the space can be saved. Further, since the transfer operation by the robot from the glass receiving to the positioning can be omitted, the cycle time is shortened.
