Research on vibration acquisition and analysis system of rapier Loom spindle
Journal of Intelligent and Fuzzy Systems, 2021The abnormal vibration of the loom spindle will seriously affect the quality of the textile. Based on the inherent embedded control system of the rapier loom, this paper develops an embedded system that monitors and analyzes the vibration signal of the spindle to determine the cause of the spindle failure.

Dynamics of the picking mechanism of a rapier loom
Mechanism and Machine Theory, 1992Abstract This paper deals with the mathematical modelling of the picking mechanism of a rapier loom. The dynamic model approximately respects mass, flexibility and kinematic excitation of the mechanism. It consists of two subsystems. The first subsystems is a discrete one, the second subsystem is a continuous one.

A numerical model of the weft yarn filling insertion process in rapier looms
2006 American Control Conference, 2006This paper presents a mathematical model of the weft yarn filling insertion process in rapier looms. A finite length segment of yarn is spatially discretized. Each element can interact only with the nearest neighbors by a viscoelastic interaction. The elastic and damping constants have been estimated by using experimental data obtained with different ...

Optimal analysis and application of the warp tension control system for a rapier loom
Textile Research Journal, 2021Traditional proportional–integral–derivative (PID) control performance optimization is an essential method to improve a loom’s warp tension control performance. This work proposes an improved genetic algorithm optimized PID control scheme to overcome the decline in control performance of the traditional PID control algorithm in a loom’s warp tension ...

Electronic drive control in a rapier loom
SPIE Proceedings, 2005Electronic and computer techniques, together with individual servomechanisms, were used successfully in this study to develop the electronic weft selection, electronic let-off and electronic take-up motion systems of the rapier loom. The control system configuration, operating principle, and mathematical models of electronic drives system were analyzed.
