BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a press working apparatus having a plurality of large press machines sequentially provided in series.

[0002]

2. Description of the Related Art In a press working apparatus in which a plurality of large press machines are sequentially arranged in series and a plurality of press workings are sequentially performed, a material transfer mechanism for transferring material between the press machines is provided. Such a press working device arranges a press machine of a preceding process side (hereinafter referred to as a preceding press machine) and a press machine of a succeeding process side (hereinafter referred to as a subsequent press machine) sequentially through a space in the order of processes, and each press machine has A transfer arm mechanism is provided so as to face each other, and an intermediate table is provided between the pair of transfer arm mechanisms facing each other. (Hereinafter referred to as semi-processed material) is taken out from the press machine and transferred to and mounted on the intermediate table, and the semi-processed material mounted on the intermediate table is processed by the subsequent press machine. Is supplied to a subsequent press machine by the transfer arm mechanism described above. For this purpose, the transfer arm mechanism has one end pivotally supported by the side frame of the press machine, and connects the pivot arm between the mold position of the press machine and the intermediate table. There is a driving means for rotating and moving the tip of the rotating arm up and down between the mold position and the intermediate platform position.

[0003]

In such a conventional apparatus, the transfer distance of the semi-processed material of the transfer arm mechanism is determined by the length of the rotating arm, and the length of the rotating arm is increased. Therefore, it is difficult to increase the transfer distance of the semi-processed material. For this reason, when the space between the press machines is large, the above-mentioned intermediate table is made to be a movable type, and when receiving the semi-processed material from the preceding press machine, it approaches the preceding press machine side, and also semi-processes on the subsequent press machine side. When the material is supplied, it is configured to approach the subsequent press machine side. However, if the transport mechanism is configured in this way, there is a problem that the structure of the entire press working apparatus becomes complicated and the price rises. In addition, there is a problem that maintenance is troublesome. Also, in such a press working device, since the press machine used is large,
Generally, operations such as mold replacement and maintenance and inspection are performed from the side of the press machine. Therefore, at the time of work, an operator needs to be located in a space between adjacent press machines.
Therefore, when the space between press machines is limited by the length of the rotating arm and is narrow, the work becomes difficult and the working efficiency deteriorates, and the rotating arm interferes with the work during the operation. There is also.

[Embodiment] FIG. 1 is a schematic view of a press working device of the present invention.
A large number of press machines 10 are sequentially arranged in series in the order of the multi-stage working process, that is, such that the preceding process press machine is adjacent to the subsequent process press machine. A space 20 is formed between the press machines 10, and a transport mechanism 30 is provided in each of the spaces. The semi-processed material 40 is sent by the transport mechanism 30 in a processing order. FIGS. 2 and 3 show two adjacent press machines taken out of the press working apparatus, and the preceding press machine 10 is located on the subsequent process side with respect to the preceding press machine (not shown). The subsequent press machine 10 'is positioned as a press machine in a preceding process side with respect to a press machine in a subsequent process side (not shown).

, For example, a link mechanism 36, and an intermediate table 37 provided between the pair of press machines 10, 10 '.

The transition means 31 may be any means capable of moving the bridge frame 32 horizontally or vertically. When the bridge frame 32 is moved in the horizontal direction, a guide frame that supports both ends of the bridge frame 32 and a driving device for horizontal movement are used. A female screw cylinder 301 is fixed to a base frame 30 'attached to 10, 10', and
An elevating device having a configuration in which threaded rods 311 and 311 ′ are threadedly inserted into the female screw cylinder 301 and the threaded rods 311 and 311 ′ are further rotated by a reversible rotation drive motor 312 with a brake is used. Rotating gears 313 and 313 'are fixed to the lower ends of the screw rods 311 and 311' for rotating the screw rods 311 and 311 '. It is configured to be rotatable in transmissions 314, 314 'connected to 312. The transmissions 314 and 314 'are connected by one rotating shaft 315 so as to rotate synchronously.
This causes the pair of threaded rods 311 and 311 'to rotate synchronously. In this embodiment, when the driving motor 312 rotates the rotating gears 313 and 313 'on both sides of the bridge frame 32 in the forward direction, the threaded rods 311 and 311' are turned into the female screw cylinder 3
01, the bridge frame 32 is raised by this. Conversely, when the drive motor 312 is reversely rotated, the threaded rods 311 and 311 'descend in the female screw cylinder 301. Is lowered.

Although the endless strip 33 may be provided directly on the bridge frame 32, in the embodiment, it is provided on an elevating frame 321 using the bridge frame 32 as a support. This lifting frame 321
Is a pair of left and right link mechanisms 3 provided on the bridge frame 32.

It is also possible to use a transfer device disclosed in Japanese Patent Publication No.

FIG. 4 illustrates the operation of the suction units 35 and 35 '. The first suction unit 35 on the side of the preceding press machine 10 is provided with a die 11 of the preceding press machine 10.
At the same time as it descends to adsorb the semi-processed material 40,
The second suction part 35 'on the side of the subsequent press machine 10' descends to the intermediate table 37 to suction the semi-processed material 40 on the table,
Next, the two suction portions 35 and 35 'ascend and move in the direction of arrow a in FIG. 4 to convey the semi-processed material 40 for a predetermined distance.
The first suction unit 35 is located at the position of the intermediate table 37 and the second suction unit 3
5 'is simultaneously lowered at the position of the mold 11' of the subsequent press machine 10 ', and the semi-processed material 40 to which each is adsorbed.
Is released, and then moves in the direction of arrow b to return to a predetermined original position, for example, between the intermediate 37th and each of the press machines 10, 10 ', and waits. Therefore, at this stage, both press machines 10 and 10 'can resume the press working operation, and the intermediate table 37 is equipped with the semi-processed material 40.

[0011]

According to the present invention, the suction portions 35, 35 'are shifted by the reciprocating operation of the endless strip 33, and the semi-processed material 40 is transported by the suction portions 35, 35'. Therefore, the transfer distance can be lengthened, and therefore, even if the space 20 between the press machines 10, 10 'is widened, the semi-processed material 40 can be easily transferred. Further, in the apparatus of the present invention, the transfer mechanism 30 is optionally changed to the semi-processed material 4.
Since it can be moved in the direction orthogonal to the zero transport direction and can be scattered from the space 20, there is an effect that the die replacement of the press machine and maintenance inspection can be performed without any trouble.
