Finisher with on-board loading and unloading mechanism

摘要

A finisher arrangement for surface finishing of parts, including a bowl-type centrifugal finishing device for agitating a mixture of parts and treating media within the bowl, and a handler for loading and unloading the parts/media to and from the bowl, respectively. The finishing device and handler are positioned sidewardly adjacent but on opposite sides of a rotary drive unit which defines a transfer horizontal drive axis. Arm linkages couple each of the finishing device and handler to the drive unit so that each is independently vertically swingable about the drive axis into respective loading and unloading positions.

主权项

1. A finisher arrangement for surface finishing parts, comprising:
a frame; a drive unit comprising a rotary actuator mounted on the frame and including a rotary drive shaft supported for rotation about a substantially horizontal axis; a handling device supported in a first position disposed closely horizontally adjacent a first side of the rotary drive shaft, the handling device including an upward opening hopper for accommodating therein a mixture containing a quantity of finishing media and a plurality of loose parts; a centrifugal finishing device supported in an operational position disposed closely horizontally adjacent a second side of the rotary drive shaft, the centrifugal finishing device comprising an open bowl-shaped container defining therein an upwardly opening finishing chamber for deposit of the mixture therein; a first drive linkage drivingly connectable between the handling device and the rotary drive shaft for vertical upward swinging movement of the handling device about the substantially horizontal axis from the first position into a second position wherein the upward opening hopper is disposed over a mouth of the upwardly opening finishing chamber for enabling discharge of the mixture from the upward opening hopper into the centrifugal finishing chamber; and a second drive linkage drivingly connectable between the centrifugal finishing device and the rotary drive shaft for vertical upward swinging movement of the centrifugal finishing device about the substantially horizontal axis from the operational position into an unloading position wherein the open bowl-shaped container is disposed in a partially inverted position generally above the handling device for discharge of the mixture from the open bowl-shaped container into the handling device.
