Patent
CA 2066837
There is disclosed a cam assembly for incorporation in an article feeder mechanism, and a feeder mechanism incorporating the cam assembly. The cam assembly has a cam plate having formed therein a first continuous cam track and a second relatively shallower cam track, a cam track follower including a first follower for relative movement within the first continuous track and a second follower for relative movement within the first and second cam tracks, and a drive for moving the cam track followers with respect to the cam tracks. The cam track follower is mounted to an article pick-up and each of the first and second cam tracks includes arcuate portions engaged sequentially by respective ones of the first and second followers so that the article pick-up is caused to move to an outwardly extended position and to an inwardly retracted position, respectively, relative to a central axis of said cam plate. The article pick- up is also caused to move through both a like-rotational and a counter-rotational path with regard to the direction of rotation of the drive, whereas in the known cam assemblies and feeder mechanisms movement of the pick-up is in a uniform clockwise or anti-clockwise rotational direction about the central axis.
