Ação de melhoria aplicada a esteira transportadora de toras na linha de produção de MDF

Abstract

The MDF (medium density fiberboard) is a very used material nowadays for making furniture. The MDF involves a very interesting process, from obtaining the raw material, eucalyptus and pine, to the manufacturing process of the wood fiber mattress, which precedes the pressing. The entire MDF manufacturing process is controlled via SAP system which is also responsible for maintenance management. By helping SAP, maintenance management uses Maintenance Indicators that comprise several Indicators that give us values to control the execution and efficiency of maintenance in all sectors of the MDF manufacturing, these indicators are called KPIs. Through these indicators we could measure the need for maintenance in some equipment as well as to measure the consequences of the improvements executed there. To help, the Operational Excellence sector helps through quality tools, organize, identify and measure the consequences of the improvement action that may appear through the ideas of its collaborators, so that the improvement action is well grounded mainly in the Financial aspect, which is still the most important for the manager, but also safety and environmental issues. Through this aid, we could identify, together with the responsible leaders of the area and maintenance engineering, improvement to be performed in the woodyard, specifically in the roller table, responsible for the removal of bark from the wood that was not removed in the bark. With this improvement we achieved safety, economic and environmental aspects with the reduction of scrap generation. The focus was the economic aspect that gave us a return on investment in three months, in three months of investment in the improvement we paid the project and generated savings in the exchanges of conveyors that were of six per year for two annual changes.
