| Rotor Spinning Machine is a relatively new type of spinning machine. Since the world's first rotor spinning machine from the Czech Republic was invented by Elitex, This new type of spinning machine compared with the traditional ring, because of the cancellation of Roving Machine and Winder, and its strong spinning fitness. While it can produces various kinds of natural fiber, pure and blended spinning of fiber, has lower processing fees than the ring, so popular.This topic under market background of rotor spinning machine and development requirements, proposes specific design requirements facing two problems of rotor spinning machine, Focused on solving design and implementation problems of the semi-automatic connectors and electronic yarn clearer electrical control system.1. Choose the eight bit STC chip microcontroller as control chip, use all isolation RS485 way communication with Siemens PLC224XP free com port. This plan is designed to not only support both on-line system programmable but also cheap and high reliability, realizes the semiautomatic joint approach of rotor spinning machine. This way not only increased the efficiency of its work, and also allows the joints more consistent, asymmetrical.2. Using CCD electronic yarn clearer, choosing STC89 microcontroller, design and develop the detection and control board, and uses the RS485 way in semiautomatic joint approach panel, the data is transmitted into the PLC and handled. So that it has the high detection accuracy of the electronic yarn clearer in this project, the system has good stability, the ability of anti-jamming, has a perfect yarn clearer function and flawed statistics function, all-digital set and show, modular design, user-friendly operation and maintenance.Finally, this topic makes the elaboration and improvement to the problems in process of product applications, so as the products application process more suitable for the market, has more market competitiveness in the future. |
