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.

An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and defined a delivery path;
- constantly sensing for pills falling along the delivery path of a rotary slat;
- and
- counting each pill sensed in said sensing step which falls along the delivery path to positively determine to the number of pills deposited into the respective container.
An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and define a delivery path, wherein said rotating step further comprises rotating each of the rotary slats independently with a separate drive motor;
- and
- counting each pill which falls along the delivery path of a rotary slat to positively determine to the number of pills deposited into the respective container.
An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and define a delivery path, wherein said rotating step comprises rotating each of the rotary slats independently with a separate drive motor;
- and
- counting each pill which falls along the delivery path of a rotary slat to positively determine to the number of pills deposited into the respective container,
- wherein said rotating step further comprises rotating the drive motors at a first speed until a first predetermined number of pills has been deposited in the containers and then rotating the drive motors at a slower second speed until a second predetermined number of pills has been deposited to prevent overfilling of the container.
An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and define a delivery path;
- counting each pill which falls along the delivery path of a rotary slat to positively determine to the number of pills deposited into the respective container;
- and
- comparing the number of pills deposited in each container with the number of pills deposited in at least one of the other containers.
An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and define a delivery path;
- counting each pill which falls along the delivery path of a rotary slat to positively determine to the number of pills deposited into the respective container;
- and
- stopping the rotation of the slats for which the respective containers have received a predetermined number of pills while continuing the rotation of any slats for which the respective container has not received the predetermined number of pills.
An automated method of depositing a predetermined number of pills into a series of containers comprising the steps of:
- capturing a plurality of pills in individual pill receptacles formed on a plurality of rotary slats;
- rotating the rotary slats to a position where the pills are released from the receptacles thereby allowing the pills to fall from the receptacles into the containers and define a delivery path;
- directing pressurized air into the individual receptacles during said rotating step to assist in the release of the pill engaged in the receptacle;
- and
- counting each pill which falls along the delivery path of a rotary slat to positively determine to the number of pills deposited into the respective container.
