Modular product dispensing and verification system and method
A modular, scalable prescription dispensing and verification system includes a four-tiered central conveyor, dispensing control system with stored patient orders for creating dispensing and routing itineraries, carriers transporting itineraries and dispensed medications, induction station, pairs of processing stations divided by the conveyor, including automated and manual dispensing, verification, cold chain, and ambient packaging. Crossover conveyors transport carriers between dispensing station pair members for dispensing multiple products per station pair. One conveyor tier returns empty carriers to induction, another transports carriers from each dispensing station to verification, then to packaging, another transports carriers from induction to dispensing, then to additional dispensing, another conveys carriers from induction to dispensing stations. Carrier stops halt carriers at stations for removal for processing, replacement, and transport to the next station, or deposit on another tier and transport to a different station. The system may include two conveyor modules, one for refrigerated or ambient unit-of-use items, another for ambient countables.
1. A system comprising:
at least one processor;
an ambient countable module comprising:

a rearward traveling transfer branch extending generally transversely from the central conveyor;
a product dispensing station comprising a single container packaging station and a multiple container packaging station; and
a computer-readable storage device storing instructions which, when executed by the at least one processor, cause the at least one processor to:
receive a patient order for a medication;
activate the second transport conveyor to transport the patient order from the product dispensing station to a verification station;
if the patient order does not require further processing by a special module of the system,
activate the second transport conveyor to transport the patient order having two or more containers from the verification station to the multiple container packaging station or
activate the third transport conveyor to transport the patient order having a single container from the verification station to the single container packaging station; and
if the patient order requires further processing by the special module,
activate the rearward traveling transfer branch to transport the patient order to a transfer stop where the special module is located nearby.
2. The system of claim 1 , wherein each of the first transport conveyor, second transport conveyor, and third transport conveyor extends between a proximal end of the rearward traveling transfer branch and the single container packaging station.
3. The system of claim 1 , wherein each of the first transport conveyor and second transport conveyor extends between a dispensing end near the product dispensing station and an area where the rearward traveling transfer branch overlies a portion of the central conveyor.
4. The system of claim 3 , wherein the first transport conveyor, after contents in totes are transferred to a package takeaway conveyor at the single container packaging station or the multiple container packaging station, transports empty totes to the dispensing end.
5. The system of claim 4 , wherein the package takeaway conveyor connects between the central conveyor and a shipping station positioned near a packaging end.
6. The system of claim 1 , wherein the rearward traveling transfer branch is discontinuous from the third transport conveyor of the central conveyor and is configured to operate independently from the central conveyor in a reverse direction from the verification station.
7. The system of claim 1 , wherein the rearward traveling transfer branch terminates at a conveyor end and transfers the patient order from the ambient countable module to the special module for refrigerated products.
8. A method for increasing throughput in dispensing, verifying, and packaging, the method comprising:
