Abstract
An interactive control system for controlling the automatic packaging of contact lenses in a contact lens fabrication facility, the interactive control system consisting of a first robot device for periodically transferring individual arrays of a first predetermined amount of discrete contact lens packages each containing a contact lens therein from a first station to an intermediate conveyor where the individual arrays are conveyed to a second station, and a controller for initiating a time stamp for each individual array transferred from the first station and determining elapsed time data for each individual array and for generating position status data indicating a good array or a bad array of defective lenses for each individual array as it is conveyed to the second station, the controller shifting the elapsed time data and position status data for each individual array as it is conveyed on the intermediate conveyor for transfer to the second station.
