ABSTRACT:
A dual pocket loader wheel assembly for use on a continuous motion packaging machine is disclosed. The dual pocket loader wheel assembly has an elongate tubular member supported for rotation on a framework positioned on the packaging machine with respect to a carton transport conveyor on the packaging machine. A drive frame is positioned at one end of the tubular member and rotatably supports a spaced pair of pocket loader wheels thereon. A drive motor assembly is positioned on the framework at the other end of the tubular member and is operably connected to a drive shaft extending through the tubular member and into the drive frame for rotating the dual pocket loader wheels about their axes. The loader wheel assembly includes a rotary actuator mounted on the framework and operably engaged with the tubular member for rotating the tubular member to reverse the position of the dual pocket loader wheels with respect to the carton transport conveyor. The loader wheel assembly also includes a double action cylinder for moving the framework toward and away from the carton transport conveyor for positioning each pocket loader wheel, respectively, adjacent the carton transport conveyor to seat articles placed within preformed cartons being moved on the carton transport conveyor adjacent, and past, the dual pocket loader wheel assembly. Each pocket loader wheel is sized and shaped to engage the flaps at the open end of the carton and to fold the flaps into a closed position on the open end of the carton as it passes thereby.
