Automação de conjunto de elevação em linha de montagem

Abstract

Today's society is immersed in a scenario of constant technological innovations, and the effects of these changes affect all areas of knowledge. Within the scope of industrial automation, there is a constant attempt to improve the efficiency, productivity and safety of processes, gradually improving the machines involved. In the context of Brazilian industry, this transformation is still in its early stages and there is a lot to evolve compared to more developed countries. However, this evolution is crucial to guarantee the competitiveness and efficiency of the sector. Based on this principle, this project consisted of the retrofit of a lifting assembly, aiming at perfect synchronization of its hoists to guarantee the safety of operators and increase the efficiency of the production process. A new electrical panel was installed, consisting of a Programmable Logic Controller (PLC), in addition to frequency inverters to control the electric motors. In the lifting hoists, incremental encoders were added, allowing the implementation of a closed speed control loop. A tilt sensor has been installed on the cross beam to ensure the suspended load remains level. Furthermore, mechanical adjustments were made to the set, with the aim of facilitating the installation of inductive sensors that are used to monitor the force applied to the wire rope hoist.
