Abstract(s)
A presente dissertação foi realizada em regime de estágio, numa organização ligada ao setor da cortiça. O projeto surgiu da necessidade de corrigir falhas e criar standards numa nova linha desenvolvida para produtos, nomeadamente cilindros, de Economia Circular. O trabalho consistiu na análise de output da linha, comparação entre o projetado e o obtido, correção de falhas e organização do espaço. De forma a estruturar e organizar o processo, foram criadas checklists com o intuito de criar um método de trabalho eficaz e formar os operadores. Os tempos de processo críticos foram cronometrados e analisados, o bottleneck foi encontrado e foram feitas alterações para atingir a cadência projetada. Em paralelo, foi realizada uma análise das várias falhas mecânicas encontradas, procedendo-se de seguida à sua correção. Abordou-se também alguns problemas na própria conceção da linha, tornando o processo mais fluído e limpo. Eliminou-se em grande parte o fator humano, reduzindo as intervenções do operador na máquina. Por fim, todo o espaço foi sujeito a uma organização geral, criando-se locais específicos e rotinas de limpeza e manutenção. Com a implementação das medidas propostas, obteve-se um aumento da vida útil dos equipamentos através do plano de manutenção autónoma, garantiu-se uma coerência no método de trabalho entre operadores e possibilitou-se a análise evolutiva da linha. As alterações realizadas resultaram numa redução de 98% no tempo de carregamento de cola e no aumento de 1,2 cilindros/hora na cadência da linha. Todas as falhas e interrupções de produção foram analisadas e corrigidas, agilizando-se também o processo de manutenção. Os encravamentos de material foram reduzidos em 100% na tubagem, a quantidade de desperdício foi reduzida e todo o espaço foi organizado, resultando numa redução máxima de 8 minutos para 30 segundos no transporte de big bags de cortiça.
The present dissertation was accomplished during an internship, in a cork industry connected organization. This project emerged of the necessity of correcting flaws and creating standards on a new line, developed for products, particularly cylinders, of Circular Economy. The work consisted on the analysis of line output, comparisons between the projected and the obtained, flaws correction and space corrections. In order to structure and organize the process, checklists were implemented, an efficient work method was created and the operators were trained. The critical process times were timed and analyzed, the bottleneck was found and alterations were made to reach the projected cadence. At the same time, an analysis of the various mechanical flaws found was conducted, proceeding to its correction. Some of the flaws on the conception of the line were also approached, making the process flowing and clean. The human factor was in majority eliminated, reducing the operator’s interventions in the machine. Ultimately, there was a general space organization, creating specific spaces, management and cleaning routines. With the implementation of the proposed measures, an equipment lifespan increase was obtained, through the autonomous maintenance plan, a consistency on the work method between operators was also guaranteed and the line’s evolutional analysis was enabled. The alterations resulted on a decrease of 98% on the glue charging time and the increase of 1,2 cylinders/hour on the line cadence. All the flaws and production interruptions were analyzed and corrected, speeding up the maintenance process. The material interlocks were reduced in 100% on the tubing, the waste was also reduced and all of the space was organized, leading to a maximum reduction of 8 minutes to 30 seconds on the transportation of cork big bags.
