Abstract: A magazine loader for automatically loading stacks of cartons onto a magazine of a mass feeder for supplying cartons to a packaging machine, includes a loader in which stacks of cartons are received and held, and a carriage on which the loader is pivotally mounted. The cartons are received loaded in the loader, after which the loader is pivoted from a loading position to a stacking position. The loader is then moved along a feeder conveyor for the packaging machine toward a magazine or supply of previously stacked cartons, until the stack of cartons is received and stacked against the previously loaded cartons to maintain a supply of cartons for feeding into the packaging machine.

Abstract: A system for automatically forming stacks of cartons for feeding a magazine for supplying cartons to a packaging machine includes a primary support on which the stacks of cartons are formed, and a secondary support for temporarily receiving a series of the cartons thereon as a previously formed stack of cartons is removed from the primary support. The stack of cartons collected on the primary support is moved onto a transport conveyor for transport to a loader for the magazine for feeding into the packaging machine.

Abstract: An improved segment wheel assembly for an article packaging machine is provided for picking individual carton blanks from a magazine and delivering the carton blanks to a conveyor to be carried to a packaging station of the machine. The segment wheel assembly has a pair of generally cylindrical segment wheels spaced apart from each other in end-to-end relationship. An unobstructed space is defined between the spaced segment wheels and each segment wheel has a generally rectangular cutout with the cutouts being aligned. A pick arm assembly including suction cups is disposed within the unobstructed space. A drive train rotates the segment wheels in unison and, simultaneously, oscillates the suction cup back and forth within the unobstructed space. The suction cup repeatedly grabs single carton blanks from the magazine and pulls them toward the rotating segment wheels, whose cutouts engage each carton blank and urges it toward and into the conveyor.

Abstract: A magazine pressure control is provided with pressure control wheels that are designed to regulate pressure on carton blanks being fed to a folder/gluer in a carton forming operation. These wheels are disposed around the periphery of the carton blank to urge the edges of the cartons forward and to straighten misaligned cartons. A separately controlled motor operates each half of the magazine pressure control. Each motor is controlled by a pressure sensor assembly and regulates the progression of the carton blanks through the magazine pressure control to equalize the pressure around the periphery of the carton blanks as they are presented to the pick face of the folder/gluer.

Abstract: An automated adjustable apparatus for dispensing glue includes a glue head assembly and an automated adjustment mechanism connected to the glue head assembly for adjusting the height of the glue head assembly to one of a plurality of predetermined heights corresponding to various heights of carton configurations within a article grouping and packaging machine. The adjustment mechanism may include a first servomechanism such as a pneumatic cylinder for moving the glue dispensing head into a plurality of predetermined height positions. The apparatus may include at least two glue dispensing heads on the service side of the machine into glue dispensing heads on the operations side of the machine and each independently controlled by actuation devices. Advantages include the elimination of manual adjustment on both the service and operations side of the machine to decrease changeover times.
