Description of Limit Peripheral Speed of Tangentially Located Gripping Members of Disk Hopper Feeders for Asymmetric Blanks of the Shape of Solids of Revolution

The article describes an approach for determining the probability of absence of interference from the peripheral speed of gripping members in the form of pockets uniformly arranged along the periphery of a rotating disk of mechanical hopper feeders when gripping asymmetric workpieces of the shape of bodies of revolution. Various options for gripping asymmetric workpieces in tangentially arranged gripping members are demonstrated. Processes of workpieces sinking by means of free fall, rolling or sliding at fixed position of workpiece and at its movement with some value of initial speed are considered. There are presented expressions for determination of limit circumferential speeds of tangentially located pockets for each considered method of lowering the workpiece into the pocket and graphs of dependence of limit value of circumferential speed depending on design parameters of gripping members and geometrical dimensions of asymmetric workpieces.
