Vision System in Plastic Tube Production

Challenge A leading producer of plastic tubes for common household items, faced challenges in the production process. The complexity of manufacturing plastic tubes, essential for products like toothpaste and mayonnaise, brought forth issues related to efficiency, quality control, and cost-effectiveness. The need for precise control over lacquer coverage, welding quality, and overall product inspection posed…

The producer achieved an annual saving of approximately $400,000 through a remarkable waste reduction to 3%.

In the welding stage, a vision system equipped with a 12MPix camera, macro lens, specialized illuminator, and deep learning software monitored the weld quality. Detection of poorly sealed tubes prevented potential ruptures during pressure filling, saving materials and guaranteeing high-quality production. The final inspection phase utilized a vision system with a 5Mpix camera, telecentric lens, custom lighting, Cartesian robot, positioning device, and advanced image analysis software. This automated process identified creases, deviations from roundness, and contaminants at the tube’s bottom, eliminating the need for manual quality control and enhancing efficiency and accuracy.
