An inline checkweigher is an automatic machine to measure the weight of products during crossing a conveyor belts. It is widely used a various industrial fields such as measurement of mass and classification of products.
The performance of the checkweigher is dependent on the operation speed and the accuracy of the measurement of mass of object. Much higher speed of operation and highly accurate measurement of mass of object is required.
In this study, in order to meet these demand has developed an inline checkweigher equipped with an eddy current damper. For this purpose, the mechanism of the weigh belt was improved so that the load cell mounted on the weigh belt can be in direct contact with the object. Eddy current damper(ECD) was also designed. Damping coefficient of ECD can changed by the input current applied to the coil and is proportional to the input current.
The experiments were performed for evaluating the performance of a checkweigher equipped with an eddy current damper. The experimental results shows that the checkweigher equipped with an ECD has better damping performance than the conventional checkweigher and therefore the former has a higher operation speed and higher measurement accuracy than the latter.
