ABSTRACT:
A parts separator for separating molded plastic parts from sprue-runner elements. The separator comprises a supporting frame, a hollow drum mounted for rotation about a first horizontal axis and constituting an outer separator element, and an inner separator element mounted within the drum for rotation about a second horizontal axis which is spaced from and parallel with the first axis. The drum has a plurality of apertures in its outer surface and the inner separator element includes a plurality of pins which extend through the apertures, so that rotation of the inner and outer separator elements about their respective axes causes the outer end of each pin to reciprocate within the aperture between an inner position wherein the end of the pin is flush with the outer surface of the drum to an outer position wherein the end of the pin extends substantially beyond the outer surface of the drum. The inner and outer separator elements are drivingly interconnected for simultaneous and synchronous rotation and a conveyor delivers the parts and sprue-runner elements to the outer surface of the drum.
