This relates to an abrasive cleaning machine wherein there is mounted within a suitable frame or housing a work supporting conveyor which is mounted for both reciprocatory and rotational movement. When the conveyor is in the form of a rocker barrel, the rocker barrel is only oscillated. On the other hand, when the conveyor is in the form of a cage-like conveyor, the conveyor is continuously rotated. The principal feature is the mounting of the conveyor for such rotary and reciprocating movement. This includs a support structure in the form of a support sleeve mounted for rotation and a support shaft mounted within the support sleeve for relative reciprocatory movement. The support shaft carries a pair of longitudinal ribs which are engaged by rollers carried by the support sleeve to transmit rotational movement from the support sleeve to the support shaft. Thus the supporting of the conveyor is simplified. When the conveyor is of the cage-like type, it may be provided with a suitable gate and pusher arrangement for discharging workpieces at the terminal end thereof.
An abrasive cleaning machine comprising a frame, a work supporting conveyor, and support means supporting said conveyor in said frame for axial reciprocating movement and for rotational movement, said frame having at opposite ends a support portion carrying first bearing means, a support sleeve mounted in each of said first bearing means for rotational movement within said frame, said conveyor having a support shaft at each end, second bearing means mounting each support shaft in a respective support sleeve for axial movement, first drive means connected to one of said support sleeves for effecting rotational movement of said one support sleeve, movement transferring means between said one support sleeve and a respective one of said support shafts, and second drive means connected to one of said support shafts for effecting reciprocating axial movement of said support shafts within said support sleeves whereby said conveyor is simultaneously axially reciprocated and rotated.
A cage-like conveyor for an abrasive cleaning machine, said conveyor having a discharge end, said conveyor including a housing portion at said discharge end, said housing portion including a side discharge opening, stop means normally closing said side discharge opening, said stop means being pivotally mounted relative to said housing portion for movement to an out-of-the-way position, and an actuator for engaging said stop means and moving said stop means to said out-of-the-way position, and a separate pusher for pushing a workpiece from said housing.
