Design Of Multi-spindle Synchronization Transmission Rising Machine Control System

Fluff out from the fabric surface finishing is called rising, The purpose of rising textile is to improve the style and exterior appearance of textile, which make the textile wool feel, warmth, thick, soft and increase the value of cloth.Currently, the market's requirement of raising machine shows a trend of variety, rapid, low cost, high reliability and high-tech. The conventional raising machine modulate velocity mechanically, though the control method is simple, the mechanical structure is complex, so in recent years the conventional rising machine has been eliminated. Some of the major domestic raising machine manufacturers have gradually change the design style from traditional model to a new design pattern. The research of this paper is about the PLC-based new high-performance control system of raising machine.This paper describes the raising mechanism, the hardware circuit design, the software development about the new control system of rising machine. First, analysis the whole structure of the system, including the cloth guide system structure, the rising system structure, the cylinder, the key components of needle roller, and analysis the control requirements of the overall control system, including the requirements of machine speed, system synchronization, touch screen control, tension control synchronization and stability. Then, according to the control system requirements, introduce the hardware circuit design, including the main controller and the implementation devices, and elaborate the cloth guide system, raising systems, communication systems, power system. Then based the hardware system, introduce the software design of the control system, including touch screen software design and PLC software design. The software design of the control system is divided into several modules, using multi-task-level design method. Finally, a new tension control technology, using close loop policy and PID algorithm, which could improve tension control accuracy and raise anti-interference capability was investigated. On the basis of this technology, compensation mechanism for multi axial velocity adjustment which could solve the problem of synchronization when the machine was running had been introduced. The purpose of synchronously regulating multiple spindle tension dynamically and smoothly was accomplished.
