Abstract [sv]

Nefab Plypak AB i Habo bedriver produktion och försäljning av lådor och väskor för långvarigt produktskydd. De har identifierat behovet av att rationalisera montering av beslag på sina produkter. Idag monteras beslagen genom nitning vilket är en väl beprövad metod som använts under lång tid. Behovet av mer rationell montering skapade underlag för detta examensarbete innefattande vidareutveckling av monteringsmetoder.

Kravet på möjligheter till automatiserad montering har påverkat utvecklingsprocessen mot att utveckla fästen som inte kräver ytterligare komponenter eller arbetsmoment i monteringen. De nya koncepten måste uppfylla samma krav avseende belastning och robusthet som dagens komponenter.

Resultatet av utvecklingsarbetet är ett koncept där befintlig handtagsdel används tillsammans med en nyutvecklad fästdel. Den nya fästdelen är utformad för att ersätta de tre komponenterna på den befintliga lösningen. Genom att fästet försetts med så kallade nabbar* som pressas fast i plywooden behövs inte längre någon nit eller annat fästelement. Nabbarna är försedda med flikar** vilket ger en stark och tillförlitlig lösning. Konceptet bygger på rationell montering med ett pressverktyg och kan med fördel ingå i automatiserad monteringsprocess.

Abstract [en]

Nefab Plypak AB is a producer of plywood boxes and cages used for long-term product protection. They are also a supplier of all types of long term packaging boxes. Nefab have identified the need of cut costs through rationalization of their mounting process of the fittings. The current method Nefab uses for mounting their fittings is rivet, which is a method that has been used for a long period of time. Rivet is a well known method for its reliability, though not easy to rationalize to a further level. This fact has made a good background to investigate possibilities to find new mounting methods.

Nefab have a strategy to implement an automatized production, which have influenced the development process to develop something that would not need any additional components or extra steps in the mounting process. The new concepts need to fulfill the present requirements considering the force of load as well as the strength.

The result of the development process is a concept that uses current handle part with a brand new solution for the fitting part. The new part is developed to replace the current three parts, rivet, plastic cover and fitting. The new fitting is designed with a sort of hooks that will be pressed through the plywood and lock the construction, which allow a design without a rivet. The hooks are designed with a barb that will lock the fitting, which provides a secure and strong solution. The concept is based on a rational mounting process and can be a part of an automatized mounting process.
