<p>PURPOSE:To decrease stock at the time of a process by controlling the stock amount in the process at real time, delivering using parts in time unit, in a part feeding system at the assembly line controlled on line by a computer. CONSTITUTION:When the assembly work by each stage of an assembly line 6 is completed, a pallet 8 is moved to the next stage. At this time, the information showing the work completion is transmitted to the computer 2 for control from a sensor 7. Then, the number of using parts is subtracted from the stock number of the stock data in the process stored in a magnetic disk device and it is judged as to whether the obtained result is less than a reference value or not. In the case of less than the reference value, a delivery instruction is output to an automatic warehouse control device 4 from the computer 2. A tray 9 delivered from the automatic warehouse 3 is transferred to an instructed stage by a conveyor 5 and the number of parts delivered is added to the number of stock of the stock data in the process stored in the magnetic disk device 10.</p> |
