<p>When a plate material reaches a support part, a press machine outputs a start signal to move a press part downward. An input receiving unit receives input of the start signal (S11). A detection unit detects that the press machine is in an operating state (S12). When the press machine moves the press part upward, and shaping of the plate material ends, the press machine outputs a standby signal. The input receiving unit receives input of the standby signal (NO in S11, YES in S13). The detection unit detects that the press machine is in a standby state (S14). When the plate material is again conveyed onto a roller conveyer from the support part, the press machine outputs a stop signal. The input receiving unit receives input of the stop signal (NO in S11, NO in S13). The detection unit detects that the press machine is in a stop state (S15).</p> |
