Elaboração de um plano de manutenção preventiva para as unidades de paletização robotizada em uma indústria alimentícia

Abstract

Robotics plays a fundamental role in the industrial sector, including the food industry, where process automation is essential to increase efficiency, ensure quality, and reduce costs. Maintenance is crucial for achieving these objectives due to the growing demand for machinery in the current industry and the benefits of cost reduction and increased reliability it offers to assets. Companies that do not adopt maintenance planning and control for their machines and equipment may face setbacks that can negatively affect their productivity. The aim was to develop a preventive maintenance plan for the robotics sector in a food industry. For this, a checklist model was created for the operators of palletizing robots, data analysis was conducted, and the critical components of the sector and their service priority were identified. The action research method was used, where the researcher intervenes in the observed reality. A bibliographic survey of specific studies on maintenance planning and control was also conducted, seeking to systematically apply the considerations made by the authors. To acquire data on the availability of the robotic cell, internal control information based on control spreadsheets used by the company to manage the maintenance of its assets was used, with a sample period of four months during the year 2024. An inventory of the equipment that makes up the sector was conducted, and through the ABC curve, critical equipment was identified. The data to identify the most severe items, that is, to identify priorities, were stratified from these spreadsheets and worked through the Priority Matrix (GUT) to identify the items with the most urgent need for maintenance. The objective of the work was achieved; a maintenance plan and schedule were developed and proposed to contribute to the systematization of processes, the reduction of robot downtime and maintenance costs, and the increase in production directly related to the functioning of robotic cells.
