Innovative use of electronics in winding machines

Electronic technology in the winding machine application examples are widely varied, the emergence of these technologies not only improve the production efficiency of the winding machine, but also improve the quality of the yarn, promote the sustainable development of enterprises, and further promote the development of the textile machinery industry.

The following are the specific application examples of electronic technology in the winding machine:

1. Electronic anti-folding technology

Principle: During the winding process, when the barrel rotational speed is in specific proportion to the slot barrel rotational speed (that is, when the barrel happens to turn through a whole number of revolutions), the yarn may overlap on the barrel, which leads to some deterioration in the quality of the yarn. Therefore, in order to solve this problem, electronic anti-overlap technology has emerged and is commonly adopted by modern winders. This technology prevents yarn overlapping and improves yarn quality and stability by monitoring and adjusting the rotational speed of the slot cylinder and the barrel in real time and controlling the servo motor to adjust the rotational speed of the slot cylinder.

Application example: In the Autoconer 5 automatic winder, it utilises an electronic computer to control the speed ratio of the slot cylinder and the adjustment, and detects the cylinder speed by means of a photoelectric encoder, and detects the rotational speed of the slot cylinder in conjunction with the Eco-pack FX yarn precision length-setting device, thus achieving precise speed ratio control as well as winding length. When the critical overlapping winding diameter is reached, the computer controls the acceleration and deceleration of the servo motor driving the grooved cylinder, which effectively prevents yarn overlapping and improves the yarn quality.

2. Electronic yarn clearing technology

Principle: Another important application of electronic technology in the winding machine is the electronic yarn clearer, which can indirectly reflect the changes in the cross-sectional area of the yarn by measuring the quality of the yarn per unit length and detecting the yarn defects. When a defect is detected, the electronic yarn clearer sends a signal and cuts or marks the defective and flawed yarn breaks. The application of this technology helps to reduce yarn defects and improve yarn quality.

Application example: Autoconer 5 automatic winder is equipped with a capacitive electronic yarn clearer, which consists of a capacitive sensor, a detection circuit, an amplification circuit, an integration circuit, a signal processing circuit and a cutter drive circuit. This electronic yarn clearer can efficiently and accurately detect and remove all kinds of defects on the yarn and improve the overall quality of the yarn.

3. Tension control technology

Principle: Tension control is an important part of the winding process, so the electronic tension control technology is particularly important, it can monitor the yarn tension changes through the sensor, and automatically adjust the relevant parameters to ensure that the yarn in the winding process to maintain a stable state of tension, effectively avoiding the yarn in the winding process due to uneven tension resulting in breakage or damage.

Application example: LT2000 frequency converter for winding machine provides constant line speed control, decreasing speed control and other tension adjustment methods. In the winding machine, the tension control technology is usually combined with the electronic control system, through the sensor real-time monitoring of yarn tension, and according to the preset tension parameters automatically adjust the tension control device, such as the tension disc or pneumatic device, in order to maintain the stability of the yarn tension.

4. Automation control system

Overview: The automation control system is the core of the electronic technology in the winding machine, which integrates the electronic anti-folding, electronic yarn clearing, tension control and other technologies, and realises the comprehensive monitoring and precise control of the winding process through the computer and sensors.

Application example: In the Autoconer 5 automatic winder, the automated control system is able to set parameters centrally and record them in a closed-loop control system. The control software optimises the acceleration process by continuously comparing the speeds of the slotted cylinder and the cylinder winding, reducing the turbulent yarn layers and hairiness generated by variable speeds. At the same time, the system can also realise smooth start-up without impact and control the sliding of anti-stacking acceleration, so that the anti-stacking effect is remarkable.

5. Air ring control technology

Principle: The air ring controller is a device used to control the shape of air ring and the length of friction yarn breakage. It can be controlled by electronic technology, adjusting its high and low position to keep the stability and uniformity of the air ring, so as to even out the winding tension. The application of air ring control technology not only helps to reduce the wear and tear of yarn and improve the quality of yarn, but also further promotes the development of enterprises.

6. Other electronic technology applications

Pre-cleaner: Pre-cleaning of defects on the yarn, reducing the burden and stopping times of the electronic yarn clearer.

Yarn detection grid: Used to check the cause of stopping and ensure the smooth running of the winding process.
