Unloading system for bowl-type vibratory finishing machine

摘要

A system for unloading finished workpieces from a bowl-type vibratory finishing machine utilizes a structure defining a channel overlying a portion of the bowl, and a removable ramp member which is insertable into and removable from the bowl for selectively directing finishing media and finished workpieces from the bowl into the channel. The channel is provided with a screen through which media entering the channel will fall back into the bowl and across which finished workpieces entering the channel will pass for discharge. The ramp member is of novel, foldable construction to facilitate its insertion into and removal from the bowl. In preferred practice, the floor of the bowl is provided with a mound- shaped formation having a substantially horizontally extending top surface. The ramp member has an upper end region which is engageable with the channel-defining structure and a lower end region which is engageable with the mound-shaped formation. The ramp member cooperates with the mound- shaped formation to direct finishing media and finished workpieces from the floor of the bowl upwardly into the channel. The mound-shaped formation is hollow and provides passages for channeling fines and liquids from the bowl to drain.
