PURPOSE:To increase durability of a related member and improve productivity by lengthening the stroke and prolonging the required time to suppress the acceleration to a small value. CONSTITUTION:The length of stroke of clamping, unclamping or lift down operation of a transfer feed is made greater than a value directly required in transfer working, and the operation is made in a specified time required directly for transfer working. The remaining operation is timed to be executed in parallel with advance and return operation. By this way, acceleration related to clamping, unclamping or lift down operation is made small. |
