Abstract
The problem presented by our client is to come up with a design in order to remove waste packaging film from a steel core, which is created during extrusion of multibarrier packaging at Winpak LTD. The film is currently removed by hand using a utility knife. This process is not very time efficient, but more importantly is causing employee injury and fatigue. The objective of the project is to bring an engineering solution to the problem described above. The client has outlined needs associated with cost, safety, required time, quality and mobility. In the first phase of the project we defined the project scope and established a schedule and Gantt chart (see appendix A). From there we used a brainstorming method to come up with a concept design that we filtered and refined to end up with the top 2 concepts –a handheld machine and a fully automated machine for film removal. We then merged some features from both ideas in order to establish our final design. The final design is a spring-loaded blade that is driven along the length of the roll by an electric motor. The assembly is mounted onto a frame that sits on wheels to allow mobility. The total weight of the design is 740 pounds, and it has a final cost of $10,011.75. This new method of film removal will reduce the time required to remove the film from 30 min to 11 for a full roll. It incorporates a safety screen, which protects the operator from the moving parts. The entire design process spanned from September 2014 to December 2014, and our group is confident that our final design will accurately meet the needs and specifications of our client.
