Design av flödesorienterad montagecell
Utvärdering av layout och materialförsörjning vid Emhart Glass AB
Emhart Glass is the world?s leading manufacturer of equipment, controls and components to the glass container industry. The goal of this project has been to identify improvements and propose cost saving solutions when moving one of Emhart Glass work cells in Sundsvall. The changes shall result in improved work environment and increased product quality. The method contains value stream mapping, concept selection and P-FMEA and complies with Emhart Glass goal to become a more Lean focused business. The way of working with Lean Production is to systematically decrease waste and focus on value added activities. The improvements in the work environment areas consider physical, ergonomic and psychosocial aspects. Concepts for supply of material and assembly process were created from the results of the observation study and the value steam mapping. After evaluation of the concepts, kitting and assembly with one piece flow appears to be the most qualified concepts. Kitting and one piece flow leads to increased quality, improved work environment and reduced cycle time. Results from tests made with prototypes of assembly pallets gave valuable insights that helped refining the concepts. A risk analysis was made in form of aP-FMEA and it showed a critical failure mode that required action. Kitting was identified as a possible action to the critical failure mode, which strengthens the concept of kitting as a preferred method. The project also resulted in a layout which improves the work environment and renders the possibility of one piece flow assembly. In order to meet future requirements with decreased cycle times, Emhart Glass isrecommended to standardize kitting in pallets for all their work cells and develop their internal transport system with a time based truck transport process.
