APLICAÇÃO DE MALHA FECHADA EM UM SISTEMA DE FRENAGEM INDUSTRIAL TÊXTIL

Abstract

With the textile sector following an increasingly competitive trend, increasing the search of organizations for optimized and reliable systems, so that they standardize processes, following compliance standards, making the use of automated control systems indispensable. The main objective of this work was to develop a closed-loop braking system through the control system techniques, so that it operated as required by the process according to the pressure of the brakes as the spools of thread decrease while maintaining its tensioning and its implantation in a machine called Índigo DENIM in order to improve the braking control and the dyeing process. To achieve this goal, initially an introduction was presented with the main concepts of the process of the DENIM Indigo machine , on control systems with emphasis on the types of existing control systems, industrial drivers, as well as tools and software used to prove the system developed through its mathematical modelling. After its implementation, the system presented satisfactory results in the braking control, which met the requirements of the process, increased productivity by 19.11% and a reduction of 2.31% in the difference in hue.
