Abstract

The present study was held in a powdered milk industry located in a city in the country side of Minas Gerais and aims to reduce stops due to dirt source in the can filling line evidenced by cardboard pieces. Through the search-action method, quality tools were used and structured with in DMAIC steps. To guide the study, it was used as Sequential Graph, Brainstorming, 4W1H, Cause and Effect Diagram and "5 reasons". It was possible to identify the roots causes of the dirt source which led to increase the index of unplanned stops and impacting on the continuity of the Factory TPM implementation, specific in the Autonomous Maintenance Pillar. Finally, with the analyzes obtained, improvement and standardization actions were proposed both in the factory and in the provider of cardboard boxes, resulting in a reduction of around 90% of the presence of cardboard pieces in the production line and almost 100% reduction of the unplanned stops caused by the cardboard pieces.
