<P>PROBLEM TO BE SOLVED: To provide a control method of a tandem press line capable of preventing interference of a press machine with a robot, improving the sheet conveying efficiency, and enhancing the productivity of the press working. <P>SOLUTION: A first monitoring area P1 includes a first holding unit 23 and a pre-pressing sheet W1, a second monitoring area P2 includes a slide 11 and an upper die 13, and a third monitoring area P3 includes a second holding unit 33 and a post-pressing sheet W2. In the control method of the tandem press line 100, the first shortest distance T1 between the first monitoring area P1 and the second monitoring area P2, the second shortest distance T2 between the first monitoring area P1 and the third monitoring area P3, and the third shortest distance T3 between the second monitoring area P2 and the third monitoring area P3 are monitored, and the operations of the press machine 10, an upstream side robot 20 and a downstream side robot 30 are controlled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
