Abstract

A fitment inserter machine, such as a machine for inserting a spout into the top opening of a blow molded container is disclosed. A conveyor continually moves containers through the machine. A transfer arm and rotary placer removes the lowermost spout from a vertical dispenser and places the spout on a moving container. Jaws grasp the container finish while it is still moving and hold the finish while a pressing head mounted on a flying table moves downwardly to press the spout into correct alignment with the container.

9. A fitment inserter machine for inserting a fitment into a container having an opening for receiving such fitment, the machine comprising, conveyor means for serially moving a plurality of containers;

placer means for placing a fitment at a container opening while such container is moving; and

,

pressing means for pressing such fitment into such container while such container is moving, said pressing means including a flying platform mounted for movement adjacent the moving containers, a vertically movable head on said platform for pressing the fitment into the container opening, jaw means carried by said platform for grasping and holding the container portion adjacent said opening and means for closing said jaw means around said container portion and holding the jaw means closed while the moveable head is lowered to press said fitment into said container opening.

10. A fitment inserter machine for inserting a fitment into a container having an opening for receiving such fitment, the machine comprising, conveyor means for serially moving a plurality of containers,

placer means for placing a fitment at a container opening while such container is moving, said placer means including a dispenser for holding a vertical stack of such fitments, alignment means for rotating about the vertical axis defined by said stack the lowermost fitment in said stack to a correct alignment, roller means for moving the fitments downwardly, a transfer arm assembly for removing the lowermost one of the fitments from the vertical stack, and a rotatable placer means for receiving the lowermost fitment and placing such fitment in a correct alignment into the opening of a moving container,

and pressing means for pressing such fitment into such container opening while such container is moving,

said pressing means including mating jaws for grasping and holding such container adjacent such container opening during pressing of such fitment.

11.
