First Claim
1. An article handling system for holding articles and moving selected articles individually from and/or to the article handling system, comprising:
- a plurality of vertically spaced article holding trays mounted for independent rotation about a common vertical axis, each tray having a plurality of discrete article holding locations;
a tray rotating mechanism arranged to rotate a single selected tray;
a pick-and-place mechanism having an article gripper mounted for vertical and horizontal movement such that the gripper can reach any article holding location on any selected tray; and
a controller coordinating rotation of the selected tray and movement of the gripper such that the gripper can move to and from the selected article holding location.

Abstract
An article handling system and method for holding articles and moving selected articles individually from and/or to the article handling system. A plurality of vertically spaced article holding trays are mounted for independent rotation, each tray having a plurality of discrete article holding locations. A tray rotating mechanism is arranged to rotate a single selected tray, while a pick-and-place mechanism has an article gripper mounted for vertical and horizontal movement such that the gripper can reach any article holding location on any selected tray. A controller coordinates rotation of the selected tray and movement of the gripper such that the gripper can move to and from the selected article holding location. The handling system is especially useful as part of an automated system for processing multiple specimens of biological fluid in separate vials.

50. A method of individually placing an article on, or removing an article from, one of a plurality of vertically spaced trays mounted for independent rotation about a common vertical axis, each tray having a plurality of discrete article holding locations and a peripheral notch sized to accommodate a gripper mounted for vertical and horizontal movement to reach any article holding location on any selected tray, the method comprising:
-
selecting an article holding location on a selected tray;
moving the gripper downwardly through the notches of the trays above the selected tray;
rotating the selected tray and horizontally moving the gripper sufficiently to enable the gripper to access the selected article holding location; and
releasing an article to the selected article holding location if vacant, or grasping an article from the selected article holding location if occupied. - View Dependent Claims (51)
