ABSTRACT:
A transfer machine is provided with a plurality of machining units disposed in positions to correspond respectively to machining stations which constitute parts of a transfer line. Each of programmable sequence controllers respectively associated with the machining units has a program memory storing a plurality of workpiece-dependent control programs and controls the operation of an associated one of the machining units in accordance with one of the workpiece-dependent control programs designated by a data processor. The data processor is provided with a memory which stores part numbers of the workpieces respectively held on the machining stations and the kinds of machining cycles in which each of the workpieces is scheduled to be machined respectively at the machining stations. Each time the transfer line performs one-pitch transfer of the workpieces therealong, the data processor rewrites the part numbers being stored in the memory so as to renew part numbers of the workpieces being respectively held on the machining stations. The data processor then outputs program designation data based upon the part numbers and the kinds of machining cycles scheduled in the memory, so that each of the sequence controllers controls the associated machining unit in accordance with one of the workpiece-dependent control programs selected by the program designation data.
