Effektivisering av arbetsplats : Effektivisering av monteringsplats vid Wigells AB

Sammanfattning:

The work presented in this report is written at IEIs department on Linköping Institute of Technology. The report aims to increase the assembly efficiency at Wigells AB. The report shall be used as a guide for the implementation of changes at other workstations in the company. Together with Träcentrum in Nässjö, Wigells AB has identified the needs of this study and contacted IEI at Linköping Institute of Technology.

In order to implement an efficient assembly line at the company, studies on lean production have been made. This theory has been studied and together with our own views and findings at the company we have analyzed the assembly area.

Wigells is a small company that manufactures wood furniture. A major problem for the assembly of the pin seats is that the company has a wide range of different models and designs.

In order to identify problems and possible improvements we first carried out a current state analysis of the assembling area.

The current state analysis shows that there are many operations in the manufacture of pin seats which are routine. Production consists today of manual operations and no automatic equipment. The company does not wish to acquire any automatic equipment.

The assembly location is perceived by outsiders and employees of the company as disorganized. After the current state analysis was conducted and compiled, problems were identified in order to enable improvements.

Identified difficulties in assembly:

• Difficult to get an overview of the assembly area, it is perceived disorganized and cluttered assembly area
• No documentation for assembly
• Defective components from external suppliers
• Defective components from internal machines

In order to create solutions to problems discovered we had to link theory and our own views together to suggest new proposals. The major problem requiring a solution is how to pass on the existing craftsmanship and knowledge.To enhance the efficiency of the assembly area many small changes that are suggested must be implemented. The company should get the staff involved in the changes proposed in this work to get best result.
