Dynamic behavior of mass measurement system using load-cell (2nd report) -Effect of partial load distribution-

Abstract

Check-weigher using a load cell type scale is a device that measures while conveying the mass of an object to be measured. In general, load cell type scales are used stationary state, but in check-weigher, it is necessary to estimate the mass value before the scale is balance still in order to high performance. Moreover, a conveying motor is necessary in the configuration of apparatus, and this mass affects the measured value of the scale and the measuring time. In this study, a dummy conveyor was manufactured giving the mass of the motor as unbalanced load. As a result of static and dynamic analysis for the dummy conveyor, it was found that the unbalanced load is major factor to deteriorate the measurement accuracy of mass.
