Description

  The present invention relates to a press processing system. Specifically, the present invention relates to a press processing system including a press machine and a transfer robot.

2. Description of the Related Art Conventionally, a press processing system for automobile parts is configured, for example, by arranging a press machine for drawing, a press machine for trimming, a press machine for bending, and a press machine for punching in a row. The
As a result, the automobile part is processed and manufactured in the order of drawing, trimming, bending, and punching.

However, there are a wide variety of parts to be manufactured on the press line, and it is not always necessary to use four press machines, and there are parts that can be manufactured by three or two press machines. In this case, if the presses are arranged in a row, there are presses that do not operate, and productivity is reduced.
Therefore, it is conceivable to change the arrangement of the press machine, but once the press machine is installed, it is difficult to change the position easily.

In order to solve these problems, a layout is proposed in which a press line having a plurality of press machines is divided into a front stage and a rear stage, and a row is shifted from the front stage press line to provide a rear stage press line. (See Patent Document 1).
According to this proposal, since the first press line and the second press line can be operated independently, two work lines can be constructed with one press line, and productivity can be improved.
JP 2005-349436 A

  However, in the proposals as described above, since the work lines are constructed in the preceding stage and the succeeding stage by shifting the preceding press line from the succeeding press line, the configuration of the preceding and succeeding press lines cannot be changed. As a result, it cannot respond flexibly to changes in the molding procedure.

  An object of this invention is to provide the press work system which can respond flexibly to the change of a shaping | molding procedure.

  A press working system according to the present invention is a press working system comprising a plurality of press machines, and a plurality of transfer robots arranged between the plurality of press machines to transport workpieces, wherein the plurality of press machines Adjacent ones are arranged in an orientation of approximately 90 degrees with each other.

According to the present invention, since the adjacent ones of the plurality of press machines are arranged in the direction of approximately 90 degrees, the loading direction and the unloading direction of the press machines adjacent to each other are also approximately 90 degrees. Therefore, one work line can be constructed with these adjacent press machines by using the transfer robot to transfer the workpiece from one of the adjacent press machines to the other. Further, by using a transfer robot to transfer different types of workpieces to these adjacent press machines, it is possible to construct different work lines with these adjacent press machines.
In other words, a work line can be started from any of a plurality of press machines, and a work line can be constructed using an arbitrary press machine among a plurality of press machines constituting one press line. Can respond flexibly to changes.

  In this case, it is preferable that the plurality of press machines are arranged at equal intervals on the circumference of one virtual circle, and the loading direction and the unloading direction of the plurality of pressing machines are tangential directions of the virtual circle.

  According to the present invention, since a plurality of press machines are arranged on one circumference, a large space is not required for constructing a press line.

  In this case, it is preferable that the transport robot is disposed between the nearest edges of the press machines adjacent to each other.

  According to this invention, since the transfer robot is disposed between the nearest edges of the press machines adjacent to each other, the workpiece can be smoothly transferred to the adjacent press machine.

  In this case, it is preferable that the plurality of press machines are arranged on one virtual straight line, and the carry-in direction and the carry-out direction of the plurality of press machines are inclined by approximately 45 degrees with respect to the virtual straight line.

  According to the present invention, since the press machines are arranged on one virtual straight line, a large space is not required for constructing the press line.

  According to the present invention, a work line can be transported from one of the adjacent presses to the other using a transport robot, so that one work line can be constructed with these adjacent presses. Further, by using a transfer robot to transfer different types of workpieces to these adjacent press machines, it is possible to construct different work lines with these adjacent press machines. In other words, a work line can be started from any of a plurality of press machines, and a work line can be constructed using an arbitrary press machine among a plurality of press machines constituting one press line. Can respond flexibly to changes.
