| dc.description.abstract | The purpose of this project is to design a mobile visual inspection unit for identifying defects in Winpak’s bacon wrap product. The bacon wrap is a clear plastic film and consist of 4 layers; nylon, polyethylene, sealant, and a modified surface. Winpak is currently experiencing two types of defect in the bacon wrap product: one is impression and the second is gels defect. Impressions occur as a result of irregular resin deposit left on the nip-roller. Gels occur when the plastic pellets used to make the film does not fully melt when being extruded. Customer complaints due to defective product have made Winpak seek an alternative and better way of spotting defects in the bacon wrap. The goal of the mobile inspection unit is to aid the lab technicians inaccurately identifying defects in the bacon wrap, thereby minimizing customer complaints. The final design of the mobile inspection unit comprises of an overhead projector and a sliding mechanism. The overhead projector allows for more accurate detection of defects by enlarging the defects. All defects are enlarged by 6.5 times magnification with a distance of 1.5m from the projector screen. This magnification of defects allows technicians to better spot the minimum defect length of 1mm. The sliding mechanism of the design ensures the technician checks the entire area of the film sample. This is accomplished by allowing the technician to only check 11.25” by 11.25” at a time. The total time estimated to check the entire film is 2 minutes. The total cost of the inspection unit is $1871.61before tax; this includes labor, manufacturing, and material cost. The overhead projector chosen for the design is the Apollo 3400. This projector is the ideal choice for the final design because it is inexpensive, lightweight, has a large staging glass and the optimal brightness required for testing the film sample. The sliding mechanism is custom made as it was not possible to find any slider that has the required length or function needed for the design in the current market. The sliding mechanism consists of three main components: a roller, a projector bracket […] | en_US |
