Engenharia reversa de um descarregador de blanks de madeira desdobrada numa empresa de beneficiamento de madeira

Abstract

Reverse Engineering (RE) can be described as a technique characterized by the reproduction of an existing physical model, so that it can be transformed into a digital model and can verify points for improvement. Thus, with a machine or equipment already used on the market, any concern about adapting or improving becomes less difficult, as, in general, any machine to be commercialized needs to undergo productivity and safety investigations. With the update of safety standards in force in Brazil, such as Regulatory Standards 12 (Safety at Work in Machines and Equipment) and 17 (Ergonomics), it is possible to apply this method in a clearer and more modern way. Therefore, this work aims to apply ER concepts and the requirements of current standards to improve a wood blank unloader implemented in a wood processing industry in the region of Guarapuava/PR. For the application of ER in this work, the use of measuring equipment such as a caliper, conventional tape measure and laser tape measure are of fundamental importance, considering that the machine to be studied remains in operation at all times. For modeling and detailing the improvements, the SolidWorks 2021 software was used. The results obtained through this work were overwhelming to the point that the project was approved for manufacturing and installation in the study company, with its cost being completely lower than the same product purchased via import ( China), in addition to being a more updated and safe model for this company's manufacturing process. It is concluded that the development f this work was very important to put into practice all the knowledge acquired throughout the course, whether professional or personal, as experiences such as collecting measurements, 3D modeling, materials science, mechanisms, among others, in addition to conversation, presentation and arguments were also essential for the final delivery of the project, which had as one of its main objectives a saving of R$62,726.24 for the company.
