Abstract: Slidably mounted blocks with toothed wheels supporting arms of various radial extension provide variable travel distances for the gripper bar when moving in the transfer direction.

Abstract: A barrel cam turns with a shaft mounted on bearings in a cam box. Four linear bearings mounted on the outside of the box receive hollow slider tubes which are clamped to legs of an H-shaped frame which holds roller cam followers. Bearings and followers are lubricated with pressure fittings, and the cam box is drained. Parallel transfer bars connected to the frame support a feeder plate with spring loaded fingers and divider bars with inward facing forward and downward sloped channels to remove lowermost articles from stacks and to feed the articles forward. The transfer bars have pockets which receive inserts with recesses for holding edges of articles. Some of the inserts have openings for receiving horizontally oriented spring loaded retainers with inward and upward sloping article engaging faces. This application is a continuation, of application Ser. No. 005,268, filed 1-22-79, now abandoned.

Abstract: A transfer has gripper bars capable of grasping, lifting and transferring a work piece. The grasping and lifting motions are actuated by face cams. The face cams act through rocker arm linkages connected to rotatable rods having arms connected to the gripper bars. The transferring motion is actuated by a barrel cam having an axial cam curve positioned between cam followers. A lifting frame has diagonal slots which receive guide pins connected to a base frame. A rack and pinion assembly connected to the gripper bars facilitates the gripping motion. Slidably mounted blocks with toothed wheels supporting arms of various radial extension provide variable travel distances for the gripper bar when moving in the transfer direction.

Abstract: An apparatus is disclosed for automatically dispensing cups to a continuously moving flight conveyor having openings for receiving the cups and carrying the same continuously forward through a cup-filling station, a cup capping station and a cup discharge station. A cup filling means travels forwardly while filling the cups and a heat sealer means heat seals cups to the cup rims while traveling forwardly with the cups. At the discharge station, the cups are automatically lifted and transferred from openings in the flight conveyor to a take-off means as the cups continuously travel forwardly. The apparatus is also capable of being modified to operate on an intermittent feed basis with the cups stopping at each of the respective stations.
