Theoretical Study of the Infl uence of the Method of Orientation of Asymmetric Workpieces on the Feed Rate of Mechanical Disk Gear Hopper Feeaders

The article describes meth ods of gripping various types of rotation bodies asymmetric at the end faces of workpieces in mechanical disk hopper feeders. Schemes for gripping workpieces in standing position in different types of toothed hopper feeding devices with passive orientation of workpieces are presented: traditional for workpieces in the form of a cap with a heavy bottom, improved with conical and spherical annular orientators for workpieces with an asymmetric end in the form of a cone and a hemisphere, as well as an adjustable orientator that provides design versatility for different types of workpieces in the form of a cap. Mathematical models of considered types of toothed hopper loading devices are obtained when active orientation of workpieces is realized in them, and results of comparison of probability of gripping and productivity of devices at different methods of orientation for two types of workpieces are presented, including in the form of diagrams of specified parameters.
