ABSTRACT:
A linear pick-and-place drive mechanism for relocating articles with finite adjustable maximum translation stroke range and finite adjustable lift stroke range, using selective placement of a translation cam follower into one of several spaced adjustment holes along the length of a translation arm, and selective placement of a lift cam follower into one of several spaced adjustment holes along the length of a lift arm. Pivoting motion of both the translation arm and the lift arm is driven by a single plate-type drive cam having a translation cam track on one side thereof and a lift cam track on the opposite side thereof, resulting in minimal housing size and reduced power requirements.
