Y. Yamakawa, T. Yamazaki

Abstract

In this research we discuss behaviors of a high speed mass measurement system with conveyor belt (a checkweigher). The objective of this paper is a proposal of a simple dynamic model of the system. The dynamics of the checkweigher with Electro-Magnetic Force Compensation (simply called EMFC) can be approximated by a mass-springdamper system as a physical model, and an equation of motion is derived. Model parameters can be estimated from the experimental data. Then, comparisons of the simulation results with the realistic responses are carried out. Finally, effects of floor vibration on the mass measurement system will be explored. The dynamic model obtained offers practical and useful information to implement control scheme.
