Title: Metering device
Inventor: TSUKASA FUMISUKE
IPC: G01G19/387
Filed: 1991-12-28
Abstract: PURPOSE:To enable metering to be made without waiting for until a weight signal of a metering equipment becomes stable. CONSTITUTION:Commodities which are supplied from a plurality of intermediate hoppers 111-11n to a plurality of metering hoppers 121-12n are metered by metering equipments 131-13n. A weight signal of the metering equipment 131-13n is input to damping compensation circuits 141-14n. The damping compensation circuits 141-14n compensate for the input metering signal so that the metering signal after stabilization may not be exceeded based on damping characteristics which are peculiar to the metering equipment and then output it to a combination selection circuit 20. The combination selection circuit 20 selects a combination within a target weight by combinational operation of compensation weight signal and then outputs the selection signal to a metering hopper switching circuit 21, thus enabling the combined and selected commodities to be delivered simultaneously from the metering hopper.
