ABSTRACT:
An accumulator system for cartons moving to a case packer including a conveyor section interposed in the conveyor line. When a jam is detected on the delivery conveyor a stop member is activated to prevent movement of cartons. When a full slug of cartons is accumulated, an array of fingers lifts the slug an increment to clear the accumulator for more cartons from the receiving conveyor. When the delivery conveyor is again operative the stop member is retracted for normal flow from the receiving conveyor through the accumulator conveyor section. When adequate clearance is detected a second stop is activated to interrupt flow to the conveyor section so that, when it is clear of cartons, a slug of cartons in the accumulator may be reinserted into the production line.
