Abstract(s)
Com a crescente necessidade das empresas se tornarem cada vez mais competitivas, a otimização dos seus processos internos é um dos principais focos das organizações que almejam com as melhorias implementadas uma redução nos custos e aumento na qualidade dos seus produtos. A filosofia Lean tendo como foco aspetos que contribuem diretamente para a otimização de processo, tem sido uma aposta forte das organizações para a adoção de algumas das suas ferramentas no âmbito de satisfazerem estas exigências. O presente projeto centra-se, fundamentalmente, no estudo e intervenção prática com vista à redução do tempo de setup de uma máquina de laminagem na empresa Amcor e no impacto que a utilização das metodologias aplicadas têm na segurança e saúde dos operadores. O projeto nasceu da necessidade da empresa em reduzir o tempo de setup do referido equipamento que causava um impacto negativo na disponibilidade e produtividade da máquina em questão. O trabalho foi desenvolvido com base na metodologia Single Minute Exchange of Die (SMED). No final conseguiu-se uma redução do tempo geral de setup de cerca de 39% através da conversão e eliminação de tarefas internas e externas. Para isto contribuiu a colocação das tarefas externas no início e no final do setup, a formação nos procedimentos de setup de um terceiro operador e a reorganização das tarefas do setup de modo a distribuir a carga pelos operadores e a otimizar o tempo de setup. Com as melhorias implementadas no sentido de melhorar o tempo de setup, através de avaliações de risco no final de cada estágio de aplicação da ferramenta verificou-se também uma melhoria nos resultados obtidos ao nível da saúde e segurança em 15%.
With the growing need for companies to become more and more competitive, the optimisation of their internal processes is one of their main focus that aims, through the implemented improvements, the cost reduction and increase the quality of their products. The Lean philosophy, with the scope on aspects that directly contribute to process optimisation, has been a strong bet for organisations to adopt some of its tools in order to satisfy these demands. The focal point of this project is the study and practical intervention with the purpose of reducing the setup time of a rolling mill machine in the company Amcor and in the impact that the use of the applied methodologies have in the safety and health of their operators. The project was born from the need of the company to reduce the setup time of this equipment that was causing a negative impact in the availability and productivity of the machine in question. The work was developed based on the Single Minute Exchange of Die (SMED) methodology. In the end a reduction of the overall setup time of about 39% was achieved through the conversion and elimination of internal and external tasks. This was achieved by placing the external tasks at the beginning and end of the setup, training a third operator in the setup procedures and reorganising the setup tasks so as to distribute the load among the operators and optimise the setup time. With the implementation of improvements to improve the setup time, through risk assessments at the end of each stage of the tool application, there was also an improvement in the results obtained in terms of health and safety by 15%.
