Abstract

A medicament tablet dispensing system and method dispenses any selected number of tablets, up to a maximum number, with minimal dispensing delays. During fill operations, a preset number of tablets are counted and stored in dedicated storage compartments. Dispensing operations are performed in response to dispense request commands. The fill operations are performed in a manner independent from the quantity of tablets identified by the dispense request commands. During the dispensing operations for a particular dispense request command, the preset number of tablets are emptied from one or more of the dedicated storage compartments, thereby avoiding delays associated with counting all of the dispensed tablets. Moreover, the fill operations and the dispensing operations may be performed in parallel for high-throughput dispensing applications.

Claims

1. A method of dispensing tablets, comprising:

a) feeding tablets from a hopper to a counter for counting tablets supplied thereto;

b) directing counted tablets from the counter to a plurality of storage locations such that each storage location has a discrete number of tablets;

c) selecting a number of tablets to be dispensed; and

d) dispensing the number of tablets from tablets stored in at least one storage location without counting the tablets;

wherein the operations of a) and b) occur prior to the selecting of c) and the dispensing of d).

2. A method according to claim 1, wherein:

the dispensing of d) includes releasing the tablets from at least one of the storage locations such that the combined total of the tablets from the at least one storage location is equal to the selected number of tablets to be dispensed.
