Device for selectively presenting objects
View Patent ↗An assembly for selectively presenting objects includes: a frame; a carousel rotatably mounted to the frame for rotation about a generally vertical axis of rotation, the carousel including a plurality of object compartments arranged about the axis of rotation; a servomotor operably connected with the carousel, the servomotor being configured to rotate the carousel about the axis of rotation; and a controller. The controller is configured to actuate the servomotor to rotate the carousel when torque applied to the servomotor exceeds a predetermined magnitude. Such an assembly can serve as a presentation device that enables an operator to remove objects therefrom at his/her convenience.
1. A method of controlling the presentation of objects with a rotary member, comprising the steps of:
(a) detecting, with a controller, a level of angular displacement experienced by the rotary member, the rotary member housing at least one object;
(b) if the magnitude of the detected angular displacement is below a predetermined level, maintaining an angular position of the rotary member; and
(c) if the magnitude of the detected angular displacement exceeds the predetermined level, rotating the rotary member over a predetermined angular distance to present the object at a new angular position.
2. The method defined in claim 1 , wherein the objects are pharmaceutical vials.
3. The method defined in claim 2 , wherein the rotary member is associated with an automated pharmaceutical dispensing machine, and wherein the objects are exception pharmaceutical vials.
4. The method defined in claim 3 , wherein the rotating step rotates a compartment from a non-access position facing an interior portion of the automated dispensing machine to an access position facing away from the interior portion of the automated dispensing machine.
5. The method defined in claim 1 , wherein the predetermined angular distance is between about 40 and 240 degrees.
6. The method defined in claim 1 , wherein the predetermined level of angular displacement is between about 2 and 10 degrees.
7. The method defined in claim 1 , wherein the rotary member is a carousel with a plurality of compartments.
8. The method defined in claim 7 , wherein the carousel includes features for receiving an operator's finger as it imparts angular displacement to the carousel.
9. The method defined in claim 1 , wherein the controller is configured to move the rotary member over the predetermined angular distance upon a command from an operator.
10. The method defined in claim 1 , wherein the controller is configured to cease rotation of the carousel when the detector detects an attempt to displace the rotating carousel in the opposite rotative direction.
