Code Detection System that Automates Inkjet Code Inspection
Videojet Technologies Inc., Wood Dale, Ill., introduced the new Videojet Code Detection System, a combination of hardware and software that provides an enhanced level of code assurance by automatically checking for the presence of a printed code on every product.
Ideal for flat packaging with a white or light marking window, the new code detection system allows manufacturers to easily inspect inkjet-printed codes on their packaging. Using presence/absence detection, the system verifies that the amount of contrast in the marking area is sufficient, helping to catch common printing issues such as missing, mis-positioned and clipped codes.
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 automatically sends an alert signal to eject product or stop the production line, allowing operators to take corrective actions.
The system bracket holds the product detector, print head, 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.
The code detection system offers a 3-step set-up process that simplifies training and minimizes changeover time.
