Its objective was to implement and evaluate an automation system that is easy to handle for the assembly process of the motorcycle rear marker product, since it was in high levels of absenteeism and rejection, and thus ensure safety standards, quality and ergonomics. For this purpose, a field study was used as a research tool in a PIM motorcycle company, through the collection of data related to the operation on the line and technical report records containing performance indicators. When analyzing the data, it was verified that the assembly of the lock of the flag contained the process with the highest index of ergonomic problems, it was verified that it could be improved by the implantation of a pneumatic device, improving production rates without incurring risks the involved employee. With the aid of design software, the device was designed, produced, tested and deployed in the line. The results obtained were the reduction of ergonomic risks, since the operator realized a considerable force for the operation, being a mechanical device without human influence. The other result would be the elimination of problems related to the quality of the lock of the flag, and to make this device a process of continuous improvement and of great relevance for both the company and the employees involved.Item Redução de perdas com manutenção corretiva utilizando um sistemas de monitoramento em uma linha de usinagem(2021-08-20) Silva Júnior, Emerson Nascimento da; Plácido, Marisol Elias Barros; http://lattes.cnpq.br/1902514007423220; Plácido, Marisol Elias Barros; http://lattes.cnpq.br/1902514007423220; Costa, José Francisco de Caldas; http://lattes.cnpq.br/5703032306296974; Queiroga, Alberto Luiz Fernandes; http://lattes.cnpq.br/9632649964503729Currently, with the progress of automation, it is possible to capture valuable data and information from an automated process in real time, making the interpretation and use of this data the differential to take decision. With this, automation facilitates the capture of information to be passed on to maintenance managers correctly and at the correct time, maintaining the reliability of the information and being able to anticipate problems. With this in mind, this work aims to analyze the maintenance problem in a two-wheeled pole industry and propose a solution through automation. For this, the methodology was divided in four parts: analysis of the current situation, analysis of causes, analysis of proposed solutions and implementation. In the analysis of the current situation, the maintenance performance indicators were quantified. In the analysis of the causes, the root causes of the problems found were investigated. And then, the specific goals and objectives were quantified. Finally, the study of solutions and implementation of improvements in the machining process was carried out. Through this work, it was possible to visualize the losses of a maintenance process, and thereby obtain several gains. Among them, the reduction of unscheduled equipment downtime, automation of the process monitoring and a 48% reduction in MTTR at the machining plant.
