  • Weight Measurement For Supplying Or Discharging Of Specified Amounts Of Material (AREA)

Abstract

PURPOSE: To enable the measurement with high accuracy, by predicting weighed amount based on the past amount, and calculating the head and performing coincidence detection in addition to the correction, in each measurement cycle from the detection of coincidence between the weighed amount and the objective to the end of weighing.
CONSTITUTION: The total weight of raw material given is detected at a load cell 1, the output enters an AD converter 4 via a preamplifier 5 and is converted into digital value for a given interval via the signal of a reference voltage detection amplifier 3 by taking the output of the load cell 1 as the reference. The output enters a height prediction operating circuit 6 via a conversion end signal C0 of a control circuit 7, the average flow of given raw material is calculated via the control circuit 7, and the head is calculated. At a comparison section 9 for coincidence detection, the value correcting the newest digital value of the AD converter 4 with the output value of the operation circuit 6 and the set value of a set section 8 are detected for the coincidence. In coincidence, the constant amount detection signal C1 to stop the application of raw material is output. Thus, the weighing with high accuracy can be made.
