Framtagning av konceptsmodell för mekanisk avskiljning av feltryckta wellpappark

Sammanfattning: This thesis was made for EMBA Machinery AB and includes a product development process with the result of a concept model. EMBA is a company that develops and manufactures machines for the global corrugated board industry and wants to extend their solutions with a system that automatically removes the misprinted corrugated boards. The idea is to incorporate the system with the already existing processing flow and should be combined with the existing video system that validate the print quality. The concept model is a concept of the mechanical parts needed for the solution and can be used as a foundation for further work towards a product for the market. To produce this concept model methods for divergent problem solving were used. Several concept solutions were created and evaluated with the purpose of finding the best one. This concept was then developed further into a 3D-model of all the interlocking machine- and construction elements, whom in detail demonstrates the removal of misprinted boards. Calculations, which included determining moment of inertia and an acceleration curve, were also done based on data from this model with the intent of testing the plausibility of the solution and to offer a theoretical foundation on which to base further work with this concept.
