Schneider Zelio Logic series logic controller is applied to cotton spinning frame...

Since the reform and opening up, my country's cotton spinning frame has made great progress, the unit output has ranked first in the world, the product variety and technical level have been continuously improved, and the gap with the international advanced level has been narrowed. In order to continuously improve product quality and performance, solve the quality problems of FA503 spinning frame, and further improve the credibility and popularity of the enterprise, we have made bold improvements to the original FA503 spinning frame relay logic control circuit, so that the product is in function, quality and performance. , In terms of reliability, compared with the original FA503 spinning frame, it has been greatly improved, which greatly promotes the sales of this product by our factory.

The FA503 spinning frame series produced by our factory has a history of nearly 20 years since its production. Due to the high rigidity and low price of this series of machines, there are still many buyers. The original design adopts the relay logic control circuit, which has not been greatly changed so far, and the machine has a high failure rate, which brings a lot of inconvenience to the normal production of users. Spinning machine user factories often find that when the yarn is full, sometimes the "three automatic" rocker arm stroke switch seat and solenoid valve fail to act, causing normal doffing; or the ring plate runs out of the starting spinning position when starting up ( Mainly because it is relatively difficult to adjust the installation position of the travel switch, and most maintenance electricians tend to ignore the importance of overtravel to the travel switch), resulting in yarn breakage and burning of the ring plate motor, which has a certain impact on production. Although the machine has adopted a new three-automatic actuator (overrunning clutch), because the mechanism is an outsourcing part and there is no effective detection method to detect whether it meets the technical requirements of the product after installation, the machine is still due to the "three-automatic" mechanism from time to time. Failure of related components and other factors. In response to these potential hazards, we used the Zelio Logic logic controller produced by Schneider Electric for the first time in the design, and replaced the original three frequently-moving travel switches with proximity switches, which completely eliminated the failures that were easy to occur in the original machine in the past. . Four intermediate relays and two time relays are also omitted on the newly designed circuit. The adjustment parameters of the low-speed to high-speed delay time and the oil pump working time are set in the Zelio Logic LCD display, which is convenient for users to adjust and simplifies the design circuit. . Users can also use the Zelio Logic LCD screen to monitor the input and output conditions in real time. In addition, we have also used Zelio Logic LCD screens to make four alarm pages. Once the equipment fails, the fault alarm page will automatically pop up, which greatly shortens the shutdown time for maintenance and improves machine production efficiency.

1) Select the Zelio Logic series SR2B201JD host, 20-point I/O with display panel, of which 12 inputs (including 4 points 0-10V analog input), 8 relay outputs, the maximum output current is 8A, which can directly drive the AC DC inductive load. Zelio Logic also has a communication function, using its communication interface to complete remote real-time monitoring applications, greatly reducing maintenance costs. Zelio Logic series products have also passed UL, CE, CSA, GL and other product certifications, creating favorable conditions for users to export products to relevant countries. The internal control module of Zelio Logic has complete functions. There are 16 text functions, 16 timers, 16 analog comparators, 28 auxiliary relays and other functions. It can fully meet the requirements of general control systems and has a very high cost performance. . According to the electrical control requirements of the original FA503 spinning frame, the system schematic diagram is given.

2) Zelio Logic uses LADDER and FBD function block diagram programming software, which is very suitable for engineering and technical personnel to master. The LADDER programming software can also detect the program online in real time, and accurately locate the error in the program. Zelio Logic can accept a total of 120 lines of ladder diagrams, and the actual programming of the machine only uses 90 lines. In view of space limitations, only part of the ladder diagram is drawn.

After the improved design of FA503 spinning frame, the grade of the machine has been upgraded and the failure rate of the machine has been reduced. Very good results have been achieved in practical applications, and no failure has occurred. Our factory is planning to extend this technology to other products such as twisting machines. This advanced and economical smart relay is worthy of popularization and application in the field of industrial control
