ABSTRACT:
A box opening apparatus for automatically opening the closed (unsealed) flaps of cartons delivered on a conveyor. The initial lifting of the longitudinal flaps is by a stream of air or by vacuum. Thereafter the undersides of the slightly lifted flaps engage a blade which urges the flaps upward, with helical rails completing the opening of the longitudinal flaps. A drag link engages the rear lateral flap, pivoting the flap open as the carton moves along the conveyor. A hook member is coupled to an endless chain moving substantially faster than the conveyor and synchronized with the movement of cartons on the conveyor. The hook member is disposed and synchronized to engage the underside of the front lateral flap when in the closed position, and to move in an upwardly and then downwardly sloping direction followed by a horizontal trajectory segment to rotate the flap to the open position. Provisions for retaining the flaps in an open condition, as well as other features and improvements for such equipment, are disclosed.
