Abstract:
Large quantities of commodities in different sizes transported on belt conveyors should often be measured automatically by two or three conveyor belt scales. Continuous measurement can be dynamically performed by multi-stage conveyor belt scales, so that the masses of discrete objects on belt conveyors can be determined in sequence according to the different lengths. Belt conveyor scales usually have maximum capacities of less than 80kg and 130cm, and achieve measuring rates of 150 packages per minutes and more. The output signals from the multistage conveyor belt scales are always contaminated with noises due to vibrations of the conveyor and the object to be measured in motion. This measuring system consists of the three-stage conveyor belt scales with load-cells, and the photo-electro switches which detect the measuring lengths of the objects and distance between each object in sequence. The experimental results on the multi-stage conveyor belt scales suggest that the algorithms proposed in this paper are effective enough to practical applications.
