Abstract

PURPOSE: To improve the stability and accuracy of a system and to make the adjustment and correction automatic by making an analog system digital.
CONSTITUTION: A load cell 2 for detecting the weight upon a belt conveyor 1 is connected through an AD converter 4 with a subtracting circuit 5. A pulse generator 3 for detecting the moving speed of the conveyor 1 is connected directly with the circuit 5. Thus, the analog signals of the cell 2 are converted by the converter 4 into digital signals, which are fed to the circuit 5. On the basis of the reading timing signals from the generator 3, the difference between the weight Wi of the load cell and the zero corrected value Do from a compensating register 12 is obtained and is integrated by an integration memory circuit 6 so that it is compared with the reference value of a reference value presetter 8 by a comparator circuit 7. Each time the reference value is exceeded, the output is fed to an integrated weight counter 9 and to a unit time weight counter 10. The weight signals are digitally processed so that the desired objects can be attained.
