From Industry to Academic Laboratory: Lab-Scaled Industrial Web Handling System for Vision Evaluation and Detection of WrinklesIn a fast changing industrial environment, educational laboratory activities need to keep pacewith new and emerging technologies that are implemented, in order to provide students with therequired skills consistent with the newest technologies available. Current industrial settings areoften too expensive and complex to implement at an educational laboratory level. On the otherhand, the advancement of increasing efficiency and reducing the cost of manufacturing iscontingent upon innovation. In manufacturing industry oftentimes defects in products areidentified by operators examining the product. In the manufacturing of sheet products thematerial is typically a very long or continuous sheet, which is referred to as a web. Continuousweb applications often encounter wrinkles and creases as defects in the product; these first showthemselves as waves in the sheet. Using vision technology combined with the known physicalproperties of the product we can recognize and react to waves in the web that lead to thesewrinkle formations.The paper presents a capstone project developed by a team of students in our EngineeringTechnology (ET) program. This project is based on an innovative system that will reduce thecost of manufacturing of continuous-web products by eliminating the operator based wrinkledetection currently used in industry. Using vision technology combined with the physicalproperties of the product the scaled system can recognize and react to waves in the web that leadto these wrinkle formations, using a laser line generator to highlight the waves in the web, andthen using the angle relationship between the laser, the camera and the web to measure thewavelength and amplitude of the wave. To develop and test this theory, students built a fullyautomated prototype system that mimics a real continuous web machine allowing for automatictensioning and intentionally wrinkling the product and removing wrinkle defects based on visionsystem feedback. The developed model of a real web system allows for measurements in acontrolled environment, being a combination of educational laboratory set-up and an innovativeapproach to solve an existing industrial problem. This prototype is developed as laboratoryteaching equipment, allowing students to visualize, monitor, control, and improve a realindustrial manufacturing process, giving them the opportunity to grasp the complexity and theinterdisciplinary nature of those processes. This project is an innovative approach towardssolving an existing industrial problem, as well as a novel instructional and research tool. Severalcourses in our ET curricula, ranging from manufacturing to measurements and instrumentationsas well as quality control are scheduled to be impacted by this type of trans-disciplinary capstoneprojects. The paper aims mainly to emphasize the impact of this type of inter andmultidisciplinary student-led project in our curricula as well as in student learning outcomes as awhole.
