The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products. Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt. The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production. The project will also be documented for further development of the machine, to use it on other conveyors. During the working time used Fredy Olsson Principle Design, Primary Design and Manufacturing process to construct the machine. Catia V5 for the compilation of the machine in 3D, drawings, and Pay-off approach to economic calculation. The goal of the project is to run the machine, and maintenance will be low and that improving any product quality. / Projektet utfördes tillsammans med SwedSafe AB, som sysslar med hörselskydd och tillverkning av öronproppar. Eftersom att företaget är världsledande inom försäljning av dessa produkter är det viktigt att de håller en högre grad av kvalitet på dessa produkter. Tillverkning av öronproppar sker i dagsläget av en automatisk tillverkningsprocess som är delad till fyra transportband och ett av transportbanden är det som kommer beröras i projektet. Bandet som påverkas under den här processen utsätts till olika moment så som påfyllning, stängning, jäsning och uppsugning av produkter. Det bidrar till att bandet blir smutsigt, produkterna försämras och arbetsmiljön påverkas. För att öka kvalitén på produkter och förbättra arbetsmiljön krävs en automatisk rengöringsprocess som samlar upp smuts från bandet. Syftet med projektet vara att konstruera en maskin som hindrar transportbandet ifrån att bli smutsigt, bevara gjutformer rena och förbättra arbetsmiljön utan att störa produktionen. Projektet skall även dokumenteras för vidare utveckling av maskinen för att kunna använda den på andra transportband. Under arbetsgång användes Fredy Olssons Principkonstruktion, Primärkonstruktion och Tillverkningsmetod, för att konsturera maskinen. Även Catia V5 för sammanställning av maskinen i 3D samt ritningar och Pay-off metod för ekonomi beräkning. Målet med projektet vara att drivningen av maskinen och underhållning ska vara låga samt att förbättre produkternas kvalitet.

During springterm 2010 Erik Persson and Magnus Hansson performed their Thesis Work with DIAB Laholm, in Hallands County for University of Halmstad. The project has been a product development project without exterior customers. Thus it had a great emphasis on functionality and less emphasis on marketing and such. This reflects the ambition to develop machinery to be used within the production facilities of DIAB Laholm, not to be sold to exterior customers. Main objective has been to create machinery which enables the production of rotational symmetric work pieces within a NC-milling machine with 5 axles. The work pieces milled will be made of DIAB’s material Divyncell with varying densities. The project has followed Fredy Olssons method involving Principal – Primary – Manufacturing constructions. However a complete manufacturing construction has not been made since DIAB just wanted a good Primary construction which will serve as a base for finishing touches at DIAB. By the end of the project material including calculations has been sent to DIAB and they will finish the work and manufacture the machine if they find economic viability in this. The work method has been suited for this by several reasons, it was created with these projects in mind and it’s also the method most familiar to us.
