The Design of Yarn Constant Tension Feeder System

Article Preview

Abstract:

A novel constant tension yarn feed control system for automatic winder is presented in this paper which is based on analyzing the principle of the generation of yarn tension and the factors which make the tension fluctuate. DSP28035 made by TI (Texas Instruments) is adopted as the main control unit of the system to acquire the real-time yarn tension which is transmitted from a yarn tension sensor. Intelligent PID (proportional-integral-derivative) algorithm is also adopted to achieve a high-dynamic performance and an ultra-low inertia servo motor speed digital control to realize constant yarn tension feed. The system not only have the function of tension setting, over current protection, error detection and alarm, but also possess the features of simple structure, low cost, real-time control and high accuracy.
