ABSTRACT:
A mechanical handling apparatus for point to point movement has utilization grippers driven from point to point by an arm assembly comprising a piston and cylinder arrangement in which the piston is in force balance until activated by a microprocessor. The microprocessor controls the energization of an electrical solenoid of each of a plurality of valves. The grippers are carried by a load beam, supported by bearings and a selectively energizable brake for resisting motion of the load beam is mounted on a lead screw. The lead screw is driven by a stepper motor but is connected with a microprocessor, and the position of the load beam and of the brake is determined by a transducer. In operation, the microprocessor permits energization of the piston to rapidly drive the load beam and hence the grippers toward a desired point within the capture range of the lead screw. The brake is applied to stop the load beam and final, accurate positioning of the grippers is performed by energizing the stepper motor.
