[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is constructed by sequentially pressing a molding member made of an iron plate or the like with each press device.
Concerning the molding material conveying device in the press line that molds doors and bonnets for automobiles, it is possible to configure the press line particularly easily and quickly, and to save space in the factory. The present invention relates to a molded member conveying device for a press line.

[0002]

2. Description of the Related Art Generally, a molded body such as an iron plate having high strength, excellent workability, and plasticity is used for automobile bodies such as doors and bonnets. It is molded into doors of automobiles, etc. by being sequentially pressed by the press machine.

Conventionally, a press line for press-molding a member to be molded has a shuttle feeder 1 and a belt conveyor 2 between press devices P1, P2, ... For punching, molding, drawing, etc. as shown in FIG. The belt conveyor 2 and the shuttle feeder 1 are configured by arranging
The member W to be molded conveyed by is automatically or manually carried into the press devices P2, P3, ...

For example, when the member W to be molded can be automatically carried out of the press device P1 by the carry-out device 61 and can be automatically carried into the press device P2 by the carry-in device 63, the press device P1, Between P2, a shuttle feeder 1 which can convey the member W to be molded to a fixed position by a carriage driven by a servomotor is arranged.

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). The molded member W artificially taken out is placed on the belt conveyor 2, conveyed to the vicinity of the press device P3, and then artificially carried into the press device P3 for press molding.

Therefore, every time the molding of the molded member W is changed every 1-2 hours (the model number of the line sink is changed), the shuttle feeder 1 and the belt conveyer 2 are replaced to change the molded member W. We are able to respond to molding changes.

[0007]

However, if the press line is set up every time in order to cope with the molding change of the member to be molded, it takes a lot of time and labor to deteriorate the work efficiency and the facility operation rate. There was a drawback that it would end up.

Further, in the conventional press line, a shuttle feeder for replacement and a belt conveyor must be always provided near the press line. For example, a belt conveyor is not provided between the press devices P1 and P2 because the carry-out device cannot automatically carry out the press device P1 shown in FIG. 12 or the press device P2 cannot carry in the carry-in device automatically. When arranged, the molding change of the member to be molded occurs and the press devices P1 and P
A shuttle feeder is arranged in the vicinity of the press line in the case where it is possible to automatically carry out and carry in the molded member to and from the molding line 2.

For this reason, a space for arranging the shuttle feeder is required, and the press line cannot be installed in a small factory, and space saving cannot be achieved even in a factory having a large space. There was a problem.

In view of the above circumstances, the present invention provides a molding member conveying device for a press line, which enables easy and quick press line construction (setup) and space saving in a factory. To do.

[0011]

In order to achieve the above object, the present invention has a belt conveyor arranged between press machines and shuttle feeders provided on both sides of the belt conveyor, and these belt conveyor and shuttle are provided. The feeder is installed on a rotatable mounting table, of which the belt conveyor is provided with a conveyor belt for mounting and conveying the molding target member, and the shuttle feeder is provided with the molding target member at a fixed position. Carriage that can be transported to and from each other is provided, and carriages that reciprocate in conjunction with each other are provided, and attachments that connect the carriages to each other are detachably provided. By detaching this attachment, the molded member is shuttled. Transport of molded parts on press line that can be transported by either feeder or belt conveyor There is provided an apparatus.

[0012]

According to the present invention, it has both the function of the shuttle feeder used in the automation of the press line and the function of the belt conveyor used when the member to be molded is manually carried into the press machine. Therefore, when the molded member can be automatically carried out of the press device by the carry-out device and can be automatically carried into the press device of the next process by the carry-in device, it is placed between the press devices by the shuttle feeder. The molded member can be conveyed. On the other hand, when it is not possible to automatically carry out and carry in the molded member to and from the press device by means of the carry-out device and the carry-in device, the molded member can be conveyed by a belt conveyor between the press devices.

That is, when the member to be molded which has been press-molded by the press device can be carried out from the press device by the carry-out device and can be automatically carried into the press device of the next step by the carry-in device, both sides of the belt conveyor can be carried out. When the attachment is attached to the carriage of the shuttle feeder attached to, the member to be molded can be conveyed at a high speed to a fixed position by the shuttle feeder with the member to be molded placed on the attachment.

On the other hand, when the unloading device or the unloading device cannot automatically carry out or carry in the molded member to or from the pressing device, the attachment is removed from the carriage, and the molded member is placed on the conveyor belt. Will be transported in.
