Finns det lönsamhet i att bygga hyresrätter i Karlstad?
Kan kostnaderna minska om man bygger enligt passivstandard?
This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone. Therefore, safety is a big matter in these types of devices control circuits. In this design project the solution is being prepared for the future purpose that is to be CE-marked. The work has had a wide topic range with not just elements within the design subject, but also areas such as risk analysis, reliability, and pneumatics. This has resulted in many stimulating destinations in the design process before it finally led into a prototype that has been function tested. The pneumatic control system was then installed to the mechanical design witch led to the final product. During testing some disturbance in the function occurred and this will have to be corrected before some good results can be shown. Testing the prototype generated a lot of information about the product that could be used to optimize its performance.
