ABSTRACT:
An improved combination carrier and stop assembly is provided for use in automated conveyor assembly systems. The carrier includes a reject pin having two positions that flags defective workpieces and further confirms that non-defective workpieces have passed the previous quality checks. The carrier also includes an improved mechanism for being grasped and lifted by the stop assembly unit of the present invention thereby enabling the stop assembly unit to grasp and lift the carrier and workpiece above the forwardly moving conveyor. The stop assembly detects the presence of a carrier, automatically checks the defective
on-defective status of the workpiece and thereafter grasps and lifts the carrier and workpiece above the conveyor if a task is to be performed. The stop assembly also includes an air-assisted release mechanism to facilitate the release of the carrier from the stop assembly after the task is performed. A programmable controller controls the moving parts of the stop assembly.
