Abstract
In the automatic weighing of packages in motion, the sequence of products is generally completely random. Long, short, heavy and light products are passed over the conveyor belt scale in any kind of random sequence. Through the multi-stage conveyor belt scale, a weighing scale can be created which will adjust the conveyor belt length to the product length. Our interest is directed to solve many technical problems when we put the multi-stage conveyor into practical use. Consequently, our weighing algorithm proposed here will give us an accurate and desirable performance with the possible improvements.
