Lager & hantering av skivmaterial : Utvecklingsarbete hos Reklamcentra produktion
Sammanfattning: This report describes a bachelor program thesis in Technical design with orientation to production design carried out via Luleå University of Technology. The project has been performed at Reklamcentra Produktion Sverige AB and comprises 15 higher education credits. Reklamcentra produce and install exposure solutions, from simple stickers to more complex signage solutions, and are especially known for their LED-illuminated engraving- and paperflex signs. As a background to the project assignment, there is a potential order for 300 - 600 paperflex signs to be delivered within a four month time interval. An order of this magnitude entails new needs and conditions. The project is oriented towards production development and aims to map the production activities in order to determine needs and ultimately result in an action proposal. The five phases of the project have been defined as; Mapping & analysis, Requirement specification, Idea & concept development, Evaluation & selection and Detail processing. The implementation has followed a cyclical process where the phases have been worked through in turns with postponed focus for each turn. The survey started with a broad perspective to create a good information base on existing flows, working methods, and perceived problems within the production. The information collection is mainly obtained from interviews and observations of staff. Furthermore, the production process for the paperflex sign was examined more thoroughly. The sign consists of three different sheet materials which all undergo more or less extensive CNC machining and are then assembled with LED strip and detail components. Identified problems from mapping & analysis were strongly associated with the sheet materials storage units and handling. A requirement specification was drawn up containing the requirements that the conceptual solutions sought to solve and thereby established a foundation for idea development. In order to seek inspiration and experience regarding sheet materials in similar applications, a benchmarking was carried out at a glass wholesaler. Two potentially applicable and, in principle, different storage systems were examined in consultation with the supplier for the respective storage systems. A layout model that represented the existing production environment was established in SketchUp in order to be able to quickly implement and discuss different solution proposals. Idea and concept development resulted in three concepts that went further and were evaluated against an evaluation matrix inherited by the requirement specification. Winning concept from the evaluation were processed in detail where the sheet storage unit was dimensioned, and a mezzanine floor was introduced as a measure to provide a better order in the production environment. Final concept proposal is presented in different investment levels that can be implemented step by step. As a first measure, a new storage system is presented for arranging sheet materials and making them easily accessible and the introduction of the lean tool 5S. In order to meet the requirements specification to the greatest extent, it is recommended to install a Telfer - system with a vacuum yoke that can pick and place sheets from storage unit and on to CNC mill for machining.As a recommendation for continued work it is suggested to further investigate the telfer solution with constructor in order to ensure the realization of this principle.
