Vertical self-separating centrifugal finishing apparatus with automatic

Abstract

A finishing machine comprising a rotatable housing, which is preferably but not necessarily resiliently mounted, comprising: a finishing chamber for receiving and finishing parts with finishing media when the housing is in finishing position, a storage chamber adapted to receive media from the finishing chamber when the housing is rotated to a parts-separation position, a foraminous member for separating media from parts, apparatus for rotating the housing about a substantially horizontal axis from a finishing position to a parts-separation position and return, and apparatus for transfer of media from the storage chamber to the finishing chamber upon return of the housing from parts-separation position to finishing position, wherein the finishing chamber comprises an annular spinner member and complementary tub member, the spinner member being adapted to rotate about a generally vertical axis when the housing is in finishing position, and a rotational motion-producing assembly and associated drive operatively associated with the spinner member for rotation thereof, whereby the spinner member may be rotated with respect to the tub member for carrying out a finishing operation; a vibratory device for vibration of the foraminous member when the housing is in parts-separation position for separation of media from parts; and a parts exit associated with the foraminous member for exit of finished parts when the housing is in parts-separation position and under the influence of the vibratory means, is provided.
