ABSTRACT:
An overhead flight conveyor assembly for use with a continuous motion packaging machine to erect four-sided tapered paperboard cartons is disclosed. The packaging machine has an elongate carton transport conveyor supported on a framework of the packaging machine, and moving along a path of travel. The overhead flight conveyor assembly has a housing supported on the framework of the packaging machine spaced above, and in alignment with the carton transport conveyor. A trailing lug assembly is supported on the housing and extends at least partially along the length thereof, the trailing lug assembly having at least one elongate conveyor chain with a series of spaced trailing lugs affixed thereto and being moved in the direction of the path of travel in timed relationship with the carton transport conveyor. A leading lug assembly is also supported on the housing and extends at least partially along the length of the trailing lug assembly, the leading lug assembly having at least one elongate conveyor chain with a series of spaced leading lugs affixed thereto and being moved in the direction of the path of travel in timed relationship with the movement of the trailing lugs. At least one trailing lug is moved into engagement with a rear side panel of the carton as it moves along the path of travel, while a leading lug is spaced above a top panel of the carton and moved along the path of travel, and is then moved toward and into engagement with a front side panel of the carton and a false score line defined therein to complete erection of the carton into a tapered configuration as the carton continuously moves along the path of travel.
