Abstract

PURPOSE:To improve the accuracy of control by arithmetically processing the total discharge weight from a metering hopper and the total required time of required number of metering cycles, and calculating an average flow rate. CONSTITUTION:An actual average flow rate is calculated from the total discharge rate from a metering hopper 1 at the past prescribed numbers of metering cycles and the total required time of prescribed number of metering cycles. The state of the material to be metered is decided from the calculated actual average flow rate and the average discharge rate per metering cycle of the past prescribed number. From the latest state and preset target flow rate of the material to be metered, the required weight in the next metering cycle is calculated, whereby the weight in the next metering cycle is determined.
