Description
Summary:The paper concerns modelling of the angular positioning process of cuboidal objects with the system of two adjacent belts of conveyors moving in the opposite sense which create the system of two backward friction force fields. During the theoretical analyses, the Coulomb friction model and only the kinetic friction state occurrence were taken into account. The positioning process consists of two symmetrical stages of the of belts movement: uniformly accelerated and uniformly retarded – to minimize the inertia forces influence on the object motion. Properly selection of the acceleration and time of the belts motion, enables precisely rotation of the object from the initial position to the target position. The results of numerical tests show that the coefficient of friction of an object does not have a significant effect on the course of angular positioning process. In case of positioning objects with different external dimensions, it is necessary to individually select the parameters of the conveyor belt motion for each possible configuration of the object dimensions.
