Abstract
Mounted upon a servo-motor-driven longitudinally-reciprocable X-axis carriage is a servo-motor-driven laterally-reciprocable Y-axis carriage carrying an air cylinder with a vertically-reciprocable and rotatable piston rod. Mounted atop the piston rod is a fixed horizontal arm carrying a rotary actuator and a reciprocating motor respectively rotating and reciprocating a movable horizontal arm mounted on the fixed arm. Also mounted on said fixed arm and rotatable by a stepping motor is a horizontal narrow-angle video camera with high resolving power. An inclined reflector mounted on the outer end of said movable arm reflects into the horizontal camera light rays from articles underneath on a work carrier. A stationary vertical overhead wide angle video camera of lower resolving power is fixedly mounted above said work carrier and focussed thereupon. Mounted on said movable arm behind said reflector is an article-gripper stepping motor arranged to rotate, upon a vertical axis, a depending article gripper having gripping fingers operated by an air cylinder mounted on said movable arm. A modification replaces both cameras by a single vertical overhead video camera mounted on and rotated by a stepping motor upon a servo-motor-driven laterally-reciprocable Y-axis carriage which in turn is mounted upon a servo-motor-driven longitudinally-reciprocable X-axis carriage above the work carrier. The computerized electronic operating system for this device involves conventional components and is described below.
