Foldable case setup apparatus
Abstract
Abstract A CASE ERECTING APPARATUS INCLUDES A FED MAGAZINE WHICH DELIVERS A STACK OF KNOCKED-DOWN CASES, AN OPENING MECHANISM FOR SEQUENTIALLY OPENING THE CASES AS THEY ARE REMOVED FROM THE STACK, PIVOTAL ARMS FOR CLOSING THE BOTTOM END FLAPS AT A STATION ADJACENT TO MAGAZINE, AND A TRANSFER DEVICE WHICH FEEDS A CASE WITH ITS BOTTOM END FLAPS CLOSED INTO A PLOW FOR CLOSING THE BOTTOM SIDE FLAPS. THE OPENING MECHANISM INCLUDES A RECIPROCATING SUCTION DEVICE WHICH GRIPS THE FOREMOST PANEL OF THE FRONT CASE IN THE STACK AND PULLS IT FROM THE STACK, FINGERS WHICH MOMENTARILY RESTRAIN THE REARMOST PANEL OF THE FRONT CASE TO OPEN THE CASE, AND STATIONARY BREAK PLATE IN THE PATH OF THE FOREMOST END PANEL TO SHAPE THE CASE TO RECTANGULAR CONFIGURATION. AFTER THE PIVOTAL ARMS HAVE CLOSED THE BOTTOM END FLAPS, THEY SERVE AS TRACKS TO SUPPORT THOSE FLAPS WHILE THE TRANSFER DEVICE MOVES THE CASE INTO THE PLOWS. AS ADDITIONAL FEATURES, A RAM OVERFOLDS THE BOTTOM FLAPS, AND AN ADHESIVE APPLICATOR MAY BE USED TO SEAL THE BOTTOM FLAPS.
