  • Patent number: 9299210
    Abstract: A pharmaceutical dispensing system includes: a frame having first and second opposed sides; a plurality of bins configured to house pharmaceutical tablets, each of the bins being accessible from the first side of the frame for replenishment of pharmaceutical tablets; and a plurality of chutes, each of the chutes connected to and associated with a respective one of the plurality of bins, each of the chutes being accessible from the second side of the frame for dispensing of pharmaceutical tablets. A system of this configuration can facilitate operation by physically separating replenishment tasks from dispensing tasks, thereby enabling these tasks to be performed simultaneously.

  • Patent number: 8714405
    Abstract: A chute assembly for an object dispensing apparatus includes: a chute configured at a first end to attach to and convey objects from an object dispenser; a funnel having an inlet that merges with a second end of the chute and an outlet; a door attached to the funnel, the door being movable between a closed position, in which the door covers the funnel outlet and prevents access to objects within the funnel, and an open position, in which the door does not cover the funnel outlet and allows access to objects within the funnel; an object agitation unit configured to agitate objects in the funnel to prevent such objects from jamming in the funnel; and a locking unit associated with the door that prevents the door from moving to the open position without authorization.

  • Publication number: 20110031262
    Abstract: An apparatus for dispensing pharmaceutical articles includes a housing and a gas source to provide a positive pressure supply gas flow. The housing defines a hopper chamber to hold the articles, a dispensing channel fluidly connected to the hopper chamber, a drive jet outlet, and an agitation outlet. The dispensing channel has an inlet and an outlet and defines a flow path therebetween. The gas source is fluidly connected to each of the drive jet outlet and the agitation outlet to provide: a pressurized drive jet gas flow through the drive jet outlet to convey articles through the dispensing channel along the flow path; and a pressurized agitation gas flow through the agitation outlet to agitate articles in the hopper chamber.

  • Patent number: 7866506
    Abstract: An automated method for dispensing pharmaceuticals, particularly tablets and capsules, and other small discrete objects, includes: receiving prescription information, selecting a container, labeling the container, dispensing the tablets or capsules into the labeled container, applying a closure to the filled, labeled container, and offloading the container to a designated location. Preferably, the tablets are dispensed with high speed dispensing bins that employ forced air to agitate and singulate the tablets. The other functions within the system are typically carried out at stations designed to offer speed, flexibility and precision to the dispensing operation.

  • Publication number: 20100185458
    Abstract: A method of tracking the exit of a filled prescription from a storage area configured to house multiple filled prescriptions includes the steps of: providing a pharmaceutical vial filled with a prescription of a pharmaceutical for a particular patient, wherein the vial includes an RFID tag that is specific for the prescription; storing the pharmaceutical vial in the storage area; detecting the RFID tag with an RFID detector as the vial is stored in the storage area, the RFID detector being associated with a controller; removing the vial from the storage area; detecting the removal of the RIFD tag to indicate removal of the vial from the storage area; and recording the removal of the vial with the controller.
