O TPM - Total Productive Maintenance (ManutenĆ§Ć£o Produtiva Total) visa melhorias no desempenho das empresas, concentrando-se assim no corte de custos para aumentar os nĆveis de produtividade e qualidade. Desta forma, investimentos estratĆ©gicos na manutenĆ§Ć£o podem levar a um melhor desempenho do sistema de produĆ§Ć£o e, consequentemente, melhorar a posiĆ§Ć£o competitiva de mercado da organizaĆ§Ć£o. PorĆ©m, para ser eficaz, o TPM deve ser implementado em toda a empresa e com a garantia de suporte total aos trabalhadores, envolvendo a gestĆ£o de topo. A presente dissertaĆ§Ć£o, realizada numa unidade industrial de produĆ§Ć£o de rolhas naturais, foi desenvolvida com o objetivo de reduzir perdas e melhorar a produtividade dos equipamentos, recorrendo-se para tal Ć implementaĆ§Ć£o do TPM. Dentro desta metodologia, deu-se maior foco aos pilares da melhoria contĆnua, da manutenĆ§Ć£o preventiva e da manutenĆ§Ć£o autĆ³noma. Dada a dimensĆ£o do processo produtivo e a quantidade de equipamentos que o integram, optou-se por eleger um setor de atuaĆ§Ć£o. Com base no histĆ³rico de avarias, e depois de uma anĆ”lise ao estado da manutenĆ§Ć£o, optou-se por intervir na Ć”rea do DSL (separaĆ§Ć£o das rolhas por qualidade). Antes de qualquer tentativa de apresentar soluƧƵes, foi necessĆ”rio perceber o funcionamento dos equipamentos, tanto da perspetiva do operador como do tĆ©cnico de manutenĆ§Ć£o, bem como as principais avarias que os caracterizavam. O trabalho desenvolvido pode ser dividido em dois segmentos. No primeiro, conduziuse uma anĆ”lise sobre as causas de avarias mais comuns no equipamento de escolha eletrĆ³nica. Este estudo resultou na implementaĆ§Ć£o de aƧƵes de melhoria. No segundo, realizou-se a reestruturaĆ§Ć£o dos planos de manutenĆ§Ć£o preventiva, bem como a introduĆ§Ć£o de planos de manutenĆ§Ć£o autĆ³noma e checklist de inĆcio de turno. Durante este processo, foram realizados ficheiros de procedimento operacional standard, de forma a padronizar e facilitar as intervenƧƵes de manutenĆ§Ć£o. Complementarmente, foi feita a marcaĆ§Ć£o dos equipamentos, para que seja mais fĆ”cil identificar os locais de intervenĆ§Ć£o.
The TPM - Total Productive Maintenance aims to improve the performance of companies, focusing on cutting costs to increase levels of productivity and quality. Strategic investments in maintenance can lead to better performance of the production system and improve the organization's competitive market position. However, to be effective, the TPM must be implemented throughout the company and with the guarantee of full support to workers, involving top management. The present dissertation, carried out in an industrial unit to produce natural corks, was developed with the objective of reducing losses and improving the productivity of the equipment, using the TPM implementation for this purpose. Within this methodology, greater focus was placed on the pillars of continuous improvement, preventive maintenance and autonomous maintenance. Given the size of the production process and the amount of equipment that make it up, it was decided to choose a sector of activity. Based on the history of malfunctions, and after an analysis of the maintenance status, it was decided to intervene in DSL (separation of corks by quality). Before any attempt to present solutions, it was necessary to understand the functioning of the equipment, both from the perspective of the operator and the maintenance technician, as well as the main faults that characterized them. The work developed can be divided into two segments. In the first, an analysis was conducted on the causes of the most common malfunctions in the electronic choice equipment. This study resulted in the implementation of improvement actions. In the second, the preventive maintenance plans were restructured, as well as the introduction of autonomous maintenance plans and the start of shift checklist. During this process, standard operating procedure files were made to standardize and facilitate maintenance interventions. In addition, the equipment was also marked, so that it is easier to identify the intervention sites.
