Berry Plastics Promotional Cup Label Inspection

Vision Inspection Ensures Quality Products for Brand-conscious CustomerOne quick way to lose a major, brand-conscious customer is to deliver products with wrinkled or skewed labels. When Berry Plastics began labeling cups for the huge McDonalds “Monopoly” game promotion in 2003, it installed a CI-Vision “Label and Cap Inspection System” to ensure high quality products were delivered.
The one-camera system is programmed to check cups passing at high line speed for label presence, position, rotation and wrinkling. The system automatically ensures that defects are rejected downstream on the line. Previously, Berry had relied on sampling at the case packing line to catch defects.
Changeover is simple. Preparing the system to inspect a new label involves simply setting the system to “teach”, running the labeled cup past the camera and dragging four inspection tools into position. The system also compiles production statistics.
What seems a simple inspection can become more challenging when colors are difficult to “see.” Changeable camera filters and different light sources provided by CI-Vision help maximize contrast in subtle color combinations for the camera. A label with a white background against a white cup can be particularly difficult to inspect, but CI-Vision engineers worked with Berry production personnel to meet the challenge. Following the success of that first system, Berry Plastics now operates six CI-Vision “Label and Cap Inspection Systems”.
Berry Plastics uses a 1-camera CI-VISION Label and Cap Inspection System to deliver a high quality product to McDonalds.
