Konstruktion och utformning av skydd till spolverk
This thesis has been carried out in cooperation with Burseryds Bruk AB.Burseryds Bruk is a company that manufactures steel strapping. The thesis isabout developing a concept of protection that should be used to protect theoperators from the rotating parts of the machinery lines. The aim of the projectwas to improve work safety for operators working at the machines by producing aconcept for a protective device. The project's first part was based on ergonomic data collection methods tounderstand the operations performed on the machine and the hazard occurringduring the process. The methods used to collect data were, interviews,observations and questionnaires with the operators of the company. This was thenused to make the ergonomic analyzes hierarchical task analysis and link analysis. The data collected from the company's operators was used create 10 conceptswhich were then evaluated. The standard "General requirements for the designand construction of fixed and movable guards" were examined at the conceptdevelopment process. The selected protection tested and simulated in a modeled machine line whereComputer manikins used together with protection. The project ended with riskanalyzes on the developed protection with the help of simulations in the CADprogram Catia workbenches and a standard for risk analysis.
