When various processes are performed on the object to be processed in step 2, the data D of this process is taken into the data tracking means 30b and stored in the area 33a. Thereafter, when various processes in the manufacturing apparatus 2 are completed and the workpiece reaches the delivery position of the manufacturing apparatus 2, a notification to that effect is sent to the transport control means 30a. Then, the process returns to step e1 and the processed material is discharged from the J¥I unit! 2 is determined by the transport control means 30a, and in the next step e2, the transport tracking memory 3
3 is searched, and the next destination is determined from the manufacturing equipment numbers M2, M3, and M4. Here, the next destination is the manufacturing bag! ! If the value is 4, it is determined in step e3 whether or not the manufacturing apparatus 4 can accept the product. Then, if the receiving is possible, the transport control command F is sent from the transport control means 30a to the transport mechanism 9, and the workpiece is transported to the manufacturing apparatus 4. Then, when the conveyance of the object to be processed is output, in step e6 again, the area 3 of the conveyance follow-up memory 33 is outputted.
The data stored in 3a is now transferred to the conveyance tracking memory 3.
It is additionally stored in the area 35a of No. 5. In this way, the objects to be processed are transferred to each manufacturing apparatus according to the destination manufacturing apparatus numbers MO to M7 stored in the respective transport tracking memories 32 to 38! !
