Ć medida que os avanƧos tecnolĆ³gicos acontecem, o consumidor final encontra-se mais informado e torna-se cada vez mais exigente com o que pretende, este procura produtos com mais qualidade, a preƧos mais acessĆveis e com prazos de entrega rapidĆssimos. Como tal, atualmente as empresas encontram-se sobre uma tremenda pressĆ£o para se adaptarem e satisfazerem as necessidades de qualidade da procura enquanto reduzem o seu tempo de resposta e consumem menos recursos, garantindo assim a sua sobrevivĆŖncia. O presente trabalho, realizado numa corticeira que se dedica Ć produĆ§Ć£o de pisos flutuantes, Amorim Revestimentos, e teve como objetivo a reduĆ§Ć£o em 15 % do tempo nas mudanƧas de sĆ©rie em duas linhas de corte. Tal reduĆ§Ć£o irĆ” promover um aumento da flexibilidade nessas linhas permitindo assim sĆ©ries de fabrico mais pequenas, um aumento de produtividade e uma reduĆ§Ć£o de custos. Foi feita uma recolha de dados relativos Ć s mudanƧas de sĆ©rie em estudo e ao histĆ³rico de paragens nessas linhas bem como foram realizadas entrevistas informais aos trabalhadores das linhas em questĆ£o. AtravĆ©s dos dados e informaƧƵes recolhidas obteve-se o tempo mĆ©dio por setup, quais as paragens que mais impactavam as linhas e a frequĆŖncia das mesmas, assim como as maiores dificuldades que os trabalhadores encontravam quando ocorriam as mudanƧas de produĆ§Ć£o. Aplicou-se a ferramenta SMED (Single Minute Exchange of Die) Ć s duas linhas em estudo obtendo-se resultados mistos. Em Acabamentos Finais 2 houve um aumento de 2 min em relaĆ§Ć£o ao tempo observado, com a circunstĆ¢ncia atenuante de a mudanƧa de sĆ©rie passar agora a ser realizada por apenas 2 colaboradores e nĆ£o os 3 iniciais. Em Acabamentos Finais 3 obteve-se uma reduĆ§Ć£o no tempo de setup de 24 %, de 29 para 22 min. Os resultados foram alcanƧados atravĆ©s da transformaĆ§Ć£o de tarefas internas em externas, alteraĆ§Ć£o do modo operatĆ³rio dos trabalhadores, alteraĆ§Ć£o da localizaĆ§Ć£o de algumas ferramentas e modificaĆ§Ć£o de uma outra. O novo modo operatĆ³rio foi transposto para cartƵes plastificados que foram colocados nas linhas garantindo assim que os funcionĆ”rios seguem as novas indicaƧƵes.
As technological advancements occur, the end consumer becomes more informed and increasingly demanding about what he wants, estimating higher quality products, cheaper prices and faster delivery times. As such, companies today are under tremendous pressure to adapt and meet demand quality needs while reducing their response time and consuming fewer resources, thus ensuring their survival. The present work was carried out on a cork company that is dedicated to the production of floating floors, Amorim Revestimentos, and its aim was to reduce by 15% the time it takes to perform series changes in two cutting lines. Such a reduction will promote increased flexibility on these lines thus allowing for smaller manufacturing series, increased productivity and reduced costs. Data on the series changes under study and the history of stops on those lines was collected, as well as informal interviews were conducted with workers on the lines in question. Through the data and information collected, the average time per setup was obtained, which stops impacted the lines and their frequency, as well as the greatest difficulties that workers encountered when production changes occurred. The SMED tool was applied to the two lines under study and mixed results were obtained. In Final Finishes 2 there was a 2 min increase compared to the observed time, with the attenuating circumstance that the series change is now performed by only 2 collaborators and not the initial 3. In Final Finishes 3, it was obtained a reduction in setup time of 24%, from 29 to 22 min. The results were achieved by transforming internal activities into external activities, changing workers operative mode, changing the location of some tools and modifying another. The new operating mode was transposed to plastic cards that were placed on the lines thus ensuring that employees follow the new directions.
