Positive count rotary slat packaging apparatus and related methods
First Claim
1. An automated packaging apparatus for depositing a predetermined number of pills into a series of containers, comprising:
- a reservoir configured to hold a plurality of pills and defining at least one opening adjacent a lower portion thereof;
a plurality of rotary slats each having a peripheral edge portion rotatable into the opening in said reservoir, said peripheral edge portions of said rotary slats each defining a plurality of pill receptacles configured to capture a individual pill at a first position in said reservoir and release the pill at a second position outside of said reservoir;
a conveyor configured to move a plurality of open containers along a predetermined path of travel and position each container adjacent a respective rotary slat to define a delivery path extending between the second position of said rotary slat and the container such that the pills are released from the slat and fall along said delivery path into the corresponding container; and
a counting device disposed along each of said delivery paths for continuously counting pills delivered along the path such that the number of pills passing into each container can be positively determined, said counting device being positioned between the second position of the respective rotary slat and the respective container and constantly sensing for pills falling past the counting device so as to positively count all pills that fall along the delivery path and into the container regardless of the duration between each successive pill.

Abstract
An automated positive count rotary slat packaging apparatus and related methods include independently rotatable rotary slats. In one embodiment, the apparatus also includes a positive count mechanism disposed in the pill delivery path adjacent the containers and a controller which is capable of generating an alarm or determining when a bottle is filled incorrectly. Accordingly, underfilled containers can be independently filled by further rotating only the respective rotary slat. A drive device for each rotary slat is also provided having frustoconical drive wheels connected to the ends of counterrotating drive shafts. The drive wheels, which are driven by a motor, engage corresponding frustoconical drive surfaces of the rotary slats to thereby rotate the slats.
