Abstract

The paper presents results of research of a sorting process applied to a stream of unit loads (cubiform objects, parcels) transported on conveyors. The sorting process is performed by means of an active fence (flexible arm) making above the conveyor surface the working rotary motion of one degree of freedom. The manipulated loads are treated as bodies of nonlinear elastic-damping properties described by modified nonlinear Kelvin model. The equations of motion of the flexible fence, and those of the interacting object, are derived using the finite element method. The assessment of influence of constructional and exploational parameters of the fence on the course of the sorting process and dynamic forces exerted on handled loads is the main aim of carried out investigations.
