The report presents the final thesis of a bachelor’s degree for Mechanical engineering within product development and design at Jönköping University. As a concluding part of the program, this work was done by Shivani Kara and Shanemae Sareno in collaboration with ABB. ABB in Hovslätt manufactures a variety of machines with different accessories. One of the accessories is a roller conveyor for pallets. At the moment, this is a product that is purchased, but now the company wants to investigate whether it would be profitable or not to manufacture their own roller conveyor. This would, among other things, mean that the design would fit in better with their products, the dimensions can be adapted to their machines and the costs would probably be reduced. The runway shall be divided into three modules case 1, case 2 and case 3. With the help of various theories and a feasibility study, a greater understanding of the problem was created. Based on this, the requirements could be set and the requirements specification was prepared. Then the design process was started and based on the set requirements, various possible variants and concepts were conceived that could be used. Many of the concepts were disqualified because the requirements were not fully met or because there were better ways to construct it. The result is a roller conveyor with standard steel plates created for a path with 2 pallets although it is possible to build on even longer paths to fit case 1 if that is desired. For this, an exchange-station was also designed which is adapted to the system. On the finished and final roller conveyor, a FEM analysis and strength calculations were made in SolidWorks to see how well it could handle the desired weight without plastic deformation happening. During the market research, it became very clear of the problems with the conveyor on the market today and why ABB needs to design its own. As this is a real problem, this work has produced a proposal on how this can be solved and a concept that can be implemented into ABB:s machines. With a few small adjustments to the final concept, the result can hopefully lead to something ABB themselves can manufacture and use in their machines internationally.
