Description of the Related Art In recent years, automobiles such as general passenger cars and trucks have been increasing along with the development of industry and economy, and by supporting a high consumption economic structure, it is now known as a car society. The demand for the automobile tends to increase.

For automobile bodies such as doors and bonnets of the automobile, iron plates and the like (molded members) having high strength, excellent workability and plasticity are used. Are sequentially pressed by a plurality of pressing devices to be molded into automobile doors and the like.

Conventionally, a press line for press-molding the member to be molded has a shuttle feeder 1 and a belt conveyor 2 between respective press devices P1, P2, ... For punching, molding, drawing, etc. as shown in FIG. , And the molded articles w conveyed by the belt conveyor 2 and the shuttle feeder 1 are automatically or manually sequentially loaded into the press devices P2, P3, ... It has become.

For example, the member to be molded w by the carry-out device 61
Can be automatically carried out from the press device P1, and the carry-in device 6
If it is possible to automatically carry in the press device P2 by means of 3, the shuttle feeder 1 which can convey the molded member w at a fixed position by the carriage driven by the servomotor is arranged between the press devices P1 and P2, and the press line Was being automated.

On the other hand, the belt conveyor 2 is arranged between the press devices which cannot be automatically carried out by the carry-out device 61 or automatically carried in by the carry-in device 63 (for example, between the press devices P2 and P3), and the carry-out device 61, the kicker, or the like. The molded member w artificially taken out is placed on the belt conveyor 2 and conveyed to the vicinity of the press device P3, and then artificially carried into the press device P3 to be press-molded. There is.

Therefore, every time the molding of the molded member w is changed (the model number of the line sink is changed) every 1 to 2 hours, the shuttle feeder 1 and the belt conveyor 2 are replaced, and the molded member w is molded. The press line was configured (setup) to accommodate the molding change.

The above object is achieved by providing a molded-member transporting device for a press line, which is characterized in that either one of them can be transported.

[0014]

In the present invention, the apparatus for conveying the molding member of the press line has the function of the shuttle feeder used in the automation of the press line and the function of the belt conveyor used when the molding member is manually carried into the pressing apparatus. Combined with.

Therefore, if the molded member to be molded can be automatically carried out of the pressing device by the carrying-out device and the carrying-in device, and can be carried into the pressing device of the next step automatically.
The shuttle feeder conveys the molded material between the press devices, and if the molded material cannot be automatically carried out from the press device by the carry-out device or the carry-in device, or if it cannot be automatically carried into the press device, it is carried out by the belt conveyor. The member to be molded can be conveyed between the press devices.

That is, as long as the member to be molded by press molding by the pressing device can be adsorbed from the pressing device by the carrying-out device and carried out, and can be automatically carried into the pressing device of the next step by the carrying-in device, the molded product can be molded. It is necessary to accurately convey the members to a predetermined location near the carry-in device of the press machine of the next process by the shuttle feeder, but by attaching the attachments to the carriages of both shuttle feeders installed on both sides of the belt conveyor, the attachment is molded. It works to convey the member at a high speed and to a fixed position.

If the molding member press-molded by the pressing device cannot be unloaded from the pressing device by the unloading device, the kicking member or the molding member must be artificially carried out of the pressing device. If the automatic loading by the loading device is not possible in the pressing machine in the next step, it is necessary to artificially load the molding target into the press machine, so for safety and the kicker should not place the molding target on the carriage. Due to the structure that makes it impossible, the conveyor must be conveyed by a belt conveyor, but by removing the attachment, the molded member works so that it can be conveyed by the belt conveyor.
