Code Detection System
“Many customers implement standard procedures to manually check printed codes periodically during a production run. Automatic code detection provides an additional level of coding confidence by inspecting every code, and can therefore deliver an earlier alert than would typically be provided using manual inspection processes,” said Anthony Blencowe, business unit director for Videojet. The Code Detection System allows users to easily set a threshold for a code to be considered unacceptable, as well as set a limit for the number of bad codes that can be detected before a fault is indicated. When the specified quantity of bad codes is detected, the system can automatically send an alert signal to eject product or stop the production line, allowing operators to take corrective actions. “The system can help reduce scrap and rework since it aids in alerting users of code defects at the time of production, enabling issues to be resolved immediately,” added Blencowe. “Users can quickly identify the root cause of the printing error by reviewing the bad code images stored on the system controller and take action to prevent reoccurrence.” The system bracket holds the product detector, printhead, camera and print detector automatically in alignment with each other, providing optimum performance without the need for physical adjustments.
Integrated lighting takes the guesswork out of system configuration, removing the need for manual alterations and helping to eliminate errors associated with changes in ambient light. Sophisticated camera-based verification systems have been used on packaging lines for years, but they often deliver more technical capabilities than most packaging lines need and may require special training for set-up and use. The Videojet Code Detection System offers a simple 3-step set-up process that simplifies training and minimizes changeover time. Blencowe added, “Videojet has been successfully integrating advanced vision systems from leading machine vision companies for over two decades. We have taken that experience and developed a simple yet powerful tool that provides customers with an easy way to strengthen their existing quality control processes.”
