Differential pressure bottle crown inspector employing fluidic control system
Abstract
Abstract THIS APPARATUS INSPECTS THE TOPS OF BOTTLES AS THEY MOVE ALONG ON A CONVEYOR PAST AN INSPECTION POSITION. RESILIENT SENSOR HEADS CARRIED BY AIR DRIVEN CYLINDERS ON A ROTATING PLATE ENGAGE THE TOP OF EACH BOTTLE IN TURN AT THE INSPECTION POSITION. THE PLATE IS CARRIED BY STAR WHEELS WHICH ENGAGE THE SIDE OF EACH BOTTLE IN TURN AT THE INSPECTION POSITION. A PRESSURIZED SOURCE OF AIR APPLIES AIR UNDER PRESSURE TO EACH SENSOR HEAD IN TURN TO TEST THE BOTTLE TOPS FOR AIR LEAKAGE. A FLUIDIC CONTROL SYSTEM IS CONNECTED BETWEEN THE PRESSURIZED SOURCE OF AIR AND A BOTTLE REJECTOR TO EJECT A BOTTLE AUTOMATICALLY AFTER THE BOTTLE LEAVES THE INSPECTION POSITION, IF THE BOTTLE IS DEFECTIVE AND CAUSES AIR LEAKAGE WHILE IN THE INSPECTION POSITION.
