Tiivistelmä
Worker safety is an integral part in mechanical engineering and the development process. In order to continuously ensure the worker safety in their paper machines, Valmet voiced the wish for a new and updated version of protective covers. The current version provides full protection, but is inconvenient for maintenance purposes. This leads to the subject of this thesis:
What could a new safety construction for the guides in the paper machines look like, and what functions would it feature?
To start the development process, different development methods were researched to ensure a structured and correct development process. Because the topic of safety regulations is complicated, various international standards had to be analysed to ensure a solution that would meet all requirements. It was essential to understand the subject and the specific machine part, therefore the hazards of the system were analysed. The main findings are where hazards are generated and how to deal with them. Many different ideas were generated during the development process. They were combined into concepts, of which three were developed. These ideas were then modelled, drawn and analysed on the basis of their strength. The question of what a new generation of safeguards might look like was answered, and proposals for further development and implementation have been stated.
