Estudo dos tempos de parada de uma linha de embalagem de macarrão instantâneo

Abstract

This study aims to identify the main causes of productivity loss in two instant noodle packaging machines at a pasta factory. The research was motivated by a decrease in productivity compared to previous production periods. The adopted methodology was based on timing machine downtimes for 30 minutes per shift over a period of 17 days, with manual data collection regarding the reasons and duration of these stoppages. The analysis was grounded in the concepts of time and motion study, industrial maintenance, OEE (Overall Equipment Effectiveness), and Pareto analysis. The results revealed that maintenance was the main cause of stoppages in both machines. Shift B showed more operational difficulties compared to Shift A. A descriptive statistical analysis of the collected data was conducted, identifying the average and standard deviation of machine downtime durations; however, the high relative errors indicate the need for further data collection to ensure better statistical accuracy, with a relative error below 10%. It is concluded that machine productivity can be improved through actions focused on preventive maintenance, faster corrective maintenance, and operational training, as well as process standardization between shifts and machines. The study highlights the importance of analyzing machine downtime to support corrective actions and, consequently, increase productivity.
