Vision Inspection Enables Zero Defects From L'Oreal Paris

By Mettler-Toledo

L'Oréal Paris had unsuccessfully tried a variety of gray-scale inspection systems to check the correctness, position and quality of labels on its Vive Pro line of high-quality shampoos and conditioners. The installation of a full-color camera-based machine vision system from CI-Vision enabled significant progression toward the L'Oréal goal of zero packaging defects entering the marketplace.

The CI-Vision two-camera system checks front and back labels, which are "no label look" transparent labels as well as the date/lot code printed on each bottle near the label. A separate barcode reader checks barcodes, eliminating the need for a third camera. Operators prepare the system for inspection simply by holding a perfect package in front of the camera and activating the training function. Changeovers on the multi-product high-speed line require no downtime for camera movement or system adjustment.
