Title:
WEIGHING DEVICE
Document Type and Number:
Japanese Patent JP2020003386
Kind Code:
A
Abstract:
To provide a weighing device capable of improving responsiveness.SOLUTION: A combination weighing device 1 comprises: a weighing hopper 6; a load cell 20; and a signal processing unit 28 for processing a noise component that overlaps with a weighed value obtained by the load cell 20 with the use of an IIR filter F having a feedback path. The signal processing unit 28 performs first filter processing and second filter processing. The first filter processing is performed by inputting a first signal relating to a predetermined mass value of an article A, instead of an output signal relating to the weighed value obtained by the load cell 20, into the feedback path after the Nth (N is a positive integer) weighed value of the article A is obtained by the load cell 20, and before the (N+1)th weighed value of the article A is obtained by the load cell 20. The second filter processing is performed on an output signal of the weighed value after the first filter processing.SELECTED DRAWING: Figure 2
