Abstract
An apparatus for controlling the loading and feeding of tablets onto carrier plates for transfer to various processing stations of a coating system includes a novel plate indexing apparatus having a box cam follower device mounted to an engagement bar for incrementally advancing the plates in a precisely controlled manner. A second complementary shaped engagement bar provides a locking mechanism to ensure the plates are always under positive control. In one embodiment the plate indexing apparatus also controls the feeding of the tablets. An alternative embodiment includes a vacuum pick-up system for feeding tablets onto the carrier plates as the plates are incrementally advanced.
