BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material suction transfer device for transferring plate materials such as synthetic resin plates in a stacked state one by one from the top.

[0002]

2. Description of the Related Art Conventionally, as a plate material suction transfer device for transferring plate materials such as synthetic resin plates stacked on a pallet one by one from the top, the plate materials are sucked and lifted by a suction cup. It is already known that, in this state, the plate material is transferred to a predetermined work table such as a mold of a molding apparatus, and then the suction force by the suction cup is released to release the plate material.

In the conventional suction transfer device for plate materials,
The sucker is pressed against the upper surface of the plate material by utilizing the elastic force of one coil spring, and the ball joint is used to allow the sucker to swing, so that the angle of the sucker can be changed. Things were already known.

[0004]

However, for example, when a plate material such as a synthetic resin plate stacked on a pallet is deformed and waviness (undulation) is generated, the highest plate material is formed. On the other hand, it is necessary to change the angle of the suction cup and press it from above, but in the conventional device,
Since the suction force is only pressed against the plate material by using the elastic force of one coil spring, the pressing force is weak, and when the angle of the suction cup is changed by using a ball joint, Since the pressing force is weak, the plate material cannot be firmly adsorbed and lifted by the suction cup, and there is a problem that the transfer work becomes difficult.

The object of the present invention is to solve the above-mentioned problems of the prior art and to allow the suction cup to move up and down, as well as to move back and forth, and to swing at any angle. Since two coil springs are used, the pressing force of the springs strongly acts on the upper surface of the plate material even when the suction cup is tilted, so that the plate materials can be reliably attracted, and therefore, for example, they are stacked on a pallet. Even if the plate material such as the synthetic resin plate in the fixed state is deformed due to undulations (undulations), the plate material can be firmly adsorbed and lifted by the suction cup, and the plate materials are placed one by one from the top. It is an object of the present invention to provide a suction transfer device for plate materials that can be transferred smoothly and reliably one by one.
