Stacking apparatus

Abstract

Abstract STACKING APPARATUS INCLUDING A PAIR OF PARALLEL, LATERALLY SPACED, ELONGATED CONVEYOR BELTS FOR SUPPORTING THE UNDERSIDES OF ARTICLES AND CONVEYING THEM FORWARDLY ALONG A HORIZONTAL PATH. A PAIR OF ENDLESS, ELONGATED CHAINS ARE MOUNTED IN TANDEM BETWEEN THE CONVEYOR BELTS WITH THEIR UPPER REACHES PARALLELING AND BENEATH THE PATH OF THE CONVEYOR BELTS. AND ELONGATED STACKER ARM PARALLELING THE CONVEYOR BELTS IS CONNECTED TO THE CHAINS. THE ARM IS CONNECTED TO THE CHAINS IN SUCH A MANNER THAT POWERED MOVEMENT OF THE CHAINS WITH THEIR UPPER REACHES MOVING FORWARDLY CAUSES THE ARM TO MOVE SUCCESSIVELY FIRST UPWARDLY, TO A RAISED POSITION ABOVE THE PATH OF THE CONVEYOR BELTS TO LIFT AN ARTICLE FROM THE CONVEYOR BELTS, THEN FORWARDLY TO A RAISED EXTENDED POSITION, THENCE DOWNWARDLY AND BELOW SUCH PATH, AND THENCE REARWARDLY, TO A LOWERED RETRACTED POSITION. ANOTHER STACKER ARM CONNECTED TO A MATCHING PAIR OF CHAINS IS MOVED OUT-OF-PHASE WITH THE FIRST-MENTIONED ARM. A STOP MEMBER MOUNTED FORWARDLY OF THE CONVEYOR BELTS ENGAGES AND ARTICLE CARRIED BY EITHER ARM AS TE ARM IS RETRACTED, AND OPERATES TO MOVE THE ARTICLE OFF THE ARM. MOTOR-POWERED MEANS MOVES BOTH STACKER ARMS AT VARIABLE SPEEDS. AN ELEVATOR WITH PLATFORM RECEIVES ARTICLES MOVED OFF THE ARMS.
