    摘要: A computer control system for optimizing process parameters in an automated production line for producing contact lenses. The system comprises a plurality of process controllers for controlling one or more process stations of the production line, each of the controllers regulating a plurality of process control devices that each control specific production parameters used in the automated manufacture of contact lenses at the process station(s). An automated lens inspection device automatically evaluates each contact lens produced and generates inspection data for each contact lens, and a polling device polls each of the process controllers on a frequent basis to acquire process control data for each period. Further included is a correlating device for correlating the inspection data to the process control data and the contact lens data to optimize process parameters used in the production of contact lenses. A relational database is also provided for storing the process control data, the contact lens data and the inspection data received from the correlating device.

    摘要: A production line tracking and quality control system and method thereof comprises a series of pallets for carrying one or more first contact lens mold halves or one or more complementary second contact lens mold halves throughout a contact lens fabrication facility. Each pallet of the series is transported on a conveyor device throughout the fabrication facility, and each pallet includes a unique identifying code. The fabrication facility includes one or more process stations and a control device provides real time monitoring of contact lens fabrication processes at the one or more process stations. The control device further includes a tracking device for identifying the unique code of each of the pallets at one or more process stations while continually receiving monitored process condition values at each station. For each identified pallet, the control device generates process status information for memory storage in the form of a reject flag, when the process conditions are out of predetermined limits, or, an acceptance flag indicating that process conditions are within predetermined limits. The process status information is updated when the pallets are identified and the status of each pallet is checked when entering or exiting a process station.
