UPRIGHT PACKAGING MACHINE

摘要

A packaging apparatus for feeding, erecting, loading and closing cartons. The packaging apparatus comprises a generally vertically extending carton transfer mechanism for advancing cartons upwardly in step fashion from a carton infeed station adjacent the lower end of the carton transfer mechanism past a carton loading station and to a carton discharge station at the upper end of the carton transfer mechanism. A carton transfer mechanism that includes laterally spaced carton guides that are open at the front and rear sides and transfer slides that are reciprocable along the carton guides. A carton magazine supports a stack of cartons adjacent the open front side of the carton guides and a carton infeed mechanism is mounted for movement in a plane parallel to and between the guides to withdraw cartons from the end of the stack and feed the cartons with open end leading into a position between the guides. A flap folding mechanism infolds the end flaps on the cartons and holds the cartons against upward movement during upward folding of the side flaps on the ends of the carton. Adhesive is applied in a horizontal band crosswise of the path of movement of the cartons and the side flap on the upper panel of the carton is then folded downwardly to close and seal the carton.
