(Kg) is charged into the receiving container 10, and the remaining amount Z (kg) of the material 2a in the charging container 2 to be supplied to the receiving container 10 is calculated as follows. That is,
Z = A- (Q + B), where Q is the total weight (kg) of the material 10b in the container put into the receiving container 10. This state is shown in step 12. Then, the central controller (PLC) 12 determines the remaining weight Z as shown in step 13.
(kg), the powder cutting device 7 is started, and the material 2a in the input container 2 corresponding to the remaining weight Z (kg) is discharged from the discharge port 7d. This state is shown in step 14. The second measuring device 6 transmits the weighing signal to the central control unit (PLC) 1 via the second weighing unit control unit 13.
2 and the central control unit (PLC) 12
(Kg) is determined and executed as shown in step 15.
4 is stopped. Then, when a predetermined supply amount (kg) of the material 10a in the container to be charged into the receiving container 10 is determined, the present apparatus 14 restarts. Further, the material 2a in the container may be any object to be weighed, such as a liquid, regardless of powder or granules. Is obtained.
