摘要
FIELD: transport.;SUBSTANCE: readings of weight roller supports mounted on both sides of standard roller support are used, one of said weight roller supports being equipped with reference weight. Prior to operating one of weight roller supports in one idle cycle of the conveyor, empty belt weight is measured and memorised. Then two weight roller supports are used to simultaneously weigh loaded belt. Now after each complete closed path of the belt, unloaded weight is determined as a difference between total readings of weight roller support without reference weight and the weight of empty belt. At the same time, difference between readings of both weight roller supports is calculated and compared with reference weight, and in case there is a divergence, correction is introduced into unloaded weight. Weight roller support incorporates cantilever strain gages fitted between the base and the bracket and spaced apart along the rollers, reference weight being arranged on the side opposite said strain gages.;EFFECT: higher reliability and accuracy of weighing, increased efficiency.;3 cl, 4 dwg
