PURPOSE:To reduce the waiting time and improve the productivity of a machining line by enabling change in starting time of a press or a workpiece transporting device in accordance with the size of a metal mold. CONSTITUTION:In a transporting device which feeds a workpiece from a press A to a press B or from a metal mold to another matal mold, the dimensions of the metal molds and the positions of a workpiece transporting member 3 and the metal molds, corresponding to the dimensions of the metal molds are previously stored in a memory 6, while devices 7, 9 for detecting the positions of the member 3 and the metal molds are provided. Then, as metal-mold selecting switch 5 is selected in accordance with the dimension of a metal mold, a CPU8 starts operation of slides of the member 3 and the presses, in the position corresponding to the dimension of the metal mold as mentioned above. Thus. by changing the starting time of the presses and the member 3 in accordance with the dimension of the metal mold, the waiting time can be reduced and, accordingly, the productivity of a machining line can be improved. |
