Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for storing and carrying a molded plate material.

[0002]

2. Description of the Related Art In a conventional pan press, a plate material is horizontally sandwiched between a punch and a die and punched from above and below like a horizontal punch press. Then, the formed plate materials were horizontally stacked in a work storage device adjacent to the punch press, and then transferred to a machine in the next step by a work transfer device. Alternatively, the formed plate material is directly transferred horizontally to the work transfer device and transferred to the machine for the next step.

[0003]

However, in the conventional work storage device and work transfer device as described above,
Since the formed plate materials are horizontally stacked and stored, there is a problem that the formed portion is crushed. This problem is remarkable for a plate material molded on both sides. In addition, the work storage device that stores the plate material while keeping it horizontal requires a large area.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a work storage / conveyance device which can solve the above problems.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention is an apparatus for storing and carrying a molded plate material in a vertical state. A first conveyor for supporting the sheet material is extended in the transport direction, and a second conveyor for supporting the plate material and a third conveyor for supporting the plate material are erected on both sides of the first conveyor, and the first and second conveyors are provided. , While providing a large number of protrusions made of an elastic body on the supporting surface of the third conveyor for supporting the plate member,
It is characterized in that a synchronous traveling device for synchronously traveling the first, second and third conveyors is provided, and the interval between the second and third conveyors is adjustable.

[0006]

In the above structure, the plate material which has been subjected to the forming process is placed on the first conveyor. Then, since the plate material is supported by the first conveyor and also by the second and third conveyors of the plate material, the plate material is kept vertical.
The distance between the second and third conveyors is adjusted in advance in accordance with the plate dimension. After the plate material is placed on the first conveyor as described above, the plate material is conveyed by a predetermined amount in the conveying direction by appropriately operating the synchronous traveling device. Then, the next plate material can be placed on the first conveyor.
