Abstract
A checkweigher is an automatic machine to measure the weight of in-motion
products. It is usually located around the end of the production process
and ensures the weight of a product within specified limits. Any products
are taken out of line if their weights are out of the specified limits. It
is usually equipped with an optical device. It is used to make a trigger
to set the time duration to allow a product to move completely on the
weigh belt for sampling the weight. In this paper, a new method of mass
measurement for checkweighers is proposed which uses just signal
processing without the optical device. The effectiveness of the method is
shown through experiments. Also a possibility of faster estimation of
weight is shown.
