“…In addition, it takes 40 ms to identify on-line in this method, and high-speed mass measurement is difficult. Hence, the shortening of identification time was considered by the compensation of the difference in dynamic characteristics using a polynomial approximation model [4]. We have proposed EMFC (Electro-Magnetic Force Compensation) system for measuring the mass at high speed.…”

Checkweighers, that can measure the mass of a target object continuously while conveying the object on a belt conveyor, are affected by environmental vibration. As a result, accuracy of the mass measurement gets worse. To solve this problem, we have proposed a method that can eliminate the effect of the environmental vibration. This paper enhances the proposed method and improves the performance of the proposed method.

The checkweigher is a device that measures mass continuously and it carries out mass measurement while conveying an object on a belt conveyor. It is a device that operated an active role in various fields such as food, medicine, and industrial products. Although the load cell scale is often used to measure measurement in the checkweigher, due to the structure of load cell, the accuracy is susceptible to environmental vibration. It is difficult to generate low frequency input such as floor vibration with the general vibration exciter. We first manufactured a device that can reproduce environmental vibration. In this study, we present the response of the load cell to excited by the device, moreover consider the vibration compensation using an acceleration sensor.
