This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

SCA har idag cirka 280 000 hektar beskogad med contortatall (Pinus contorta Dougl. ex Loud. var. latifolia Engelm). Stora delar av den arealen har kommit in i, eller är på väg in i, gallringsbar ålder.

The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.

Sammanfattning Projektet som genomförts på uppdrag av och i samarbete med företaget ABB-I-R har innefattat att finna och dimensionera en befintlig avfuktningsenhet tillgänglig på marknaden, eventuellt med viss erforderlig anpassning och modifikation. Vidare har uppgiften innefattat att konstruera en applikation till basenhet Cutting-box Original IV. Slutligen ingick även testkörning och intrimning av framtaget lösningskoncept som en del i uppgiften. Principkonstruktion: Första konstruktionsetappen s.k. principkonstruktion inleds med en, enligt Fredy Olssons modell för produktutveckling, framtagen strukturerad uppgiftsutredning och problemställningsanalys. Denna beaktar såväl produktens förhållning till process, omgivning, människa och ekonomi, som sin egen tekniska livscykel uppdelad i etapperna alstring, framställning, avyttring och eliminering.
