Using the coasting halt position control mannered null

摘要

PROBLEM TO BE SOLVED: To improve accuracy of coil car stopping position at low cost. ;SOLUTION: In a stop position control method of a transfer machine such as a coil car to transfer the coil with a device to be driven by a linear motor 5 or a hydraulic equipment 10, which is controlled by an electrode valve 9, a transfer control to stop the machine at several given positions is made by a sequencer 1 having a CPU 22, a RAM 23. A coasted distance at the time of previous stopping is memorized in the RAM 23 and at the time of next stop, the coast distance information of the previous stopping is obtained from the RAM 23 to correct the stop coasting distance by the CPU 22 so as to improve the stop position accuracy of the transfer machine.;COPYRIGHT: (C)1999,JPO
