Device for feeding and folding the trailing top flap of a container for closing the container

Abstract

Abstract APPARATUS FOR FOLDING THE TRAILING OR REAR END FLAP INCLUDES A PLURALITY OF ROD MEMBERS WHICH ARE CARRIED ON BLOCKS ON A COMMON SUPPORT ROD. EACH BLOCK IS CONNECTED TO A FLUID PRESSURE PISTON-AND-CYLINDER COMBINATION WHICH IS ACTUATED IN ACCORDANCE WITH THE POSITION OF THE CONTAINER TO MOVE THE FOLDING ROD MEMBER DOWNWARDLY TO ENGAGE THE TRAILING TOP END FLAP. AS THE CONTAINER IS MOVED OVER THE CONVEYOR, ELECTRIC EYE CONTROL MEANS ARE CONNECTED TO THE RESPECTIVE FLUID PRESSURE CYLINDERS FOR EACH ROD MEMBER TO CAUSE THE ROD MEMBERS TO MOVE DOWNWARDLY IN SUCCESSION TO ENGAGE AND SUCCESSIVELY DEPRESS THE REAR FLAP UNTIL IT IS FULLY CLOSED AND TO HOLD IT DOWNWARDLY UNTIL OTHER MEANS ARE OPERABLE TO CLOSE THE SIDE FLAPS AND OTHER END FLAP. A DEVICE FOR FEEDING AND CLOSING A TOP TRAILING END FLAP OF A CONTAINER COMPRISES A ROLLER CONVEYOR OVER WHICH THE CONTAINER IS ADAPTED TO BE PASSED. THE ROLLER CONVEYOR INCLUDES AN INCLINED SECTION LEADING TO A TOP FLAP CLOSURE STATION WHICH EXTENDS SUBSTANTIALLY HORIZONTALLY. AT THE BEGINNING OF THE HORIZONTAL SECTION, THERE IS A ROTATABLE DRIVEN ROLLER WHICH ENGAGES AND FEEDS THE CONTAINER ONLY AFTER A STOP MEMBER IS MOVED OUT OF THE WAY TO PERMIT PASSAGE OF THE CONTAINER THROUGH THE CLOSING SECTION. THE STOP MEMBER IS MOVED DOWNWARDLY OUT OF THE WAY ONLY AFTER A CONTAINER, WHICH HAS BEEN PREVIOUSLY CLOSED, IS MOVED TO THE END OF THE FOLDING SECTION. THE STOP RETURNS UPWARDLY TO BLOCK THE NEXT CONTAINER UNTIL THE ONE BEING FOLDED IS COMPLETED. THE DEVICE INCLUDES MEANS FOR STRAIGHTENING THE CONTAINER AND FEEDING IT BY ENGAGING BOTH SIDES THEREOF WHILE THE TOP FLAPS ARE FOLDED. AN
