PURPOSE:To perform a proper job without any data correction even in the case where work conveying sequence in an assembly line is changed by factors such as branching and sampling or the like, by setting the job to be performed by each working machine in respective working stations on the basis of a number of each pallet reached to these stations. CONSTITUTION:A pallet taken into each working station is read of its number by each of pallet number reading means 4-1 to 4-99 installed in these working stations. Next, on the basis of this pallet number and the contents of a program number file, work contents of working machines 3-1 to 3-99 in these working stations are specified. In addition, the pallet number in an on-line file is assigned, and a machine type sign related to this pallet number is changed into an optional machine type sign, whereby the program number related to this type sign is read out of the control file, thus the program number related to the pallet number is corrected. |
