Why Do We Need A Web Guiding Control System in An Industrial Coil Production System?

In the web control device business, coils refer to sheet products such as paper, film, foil, fiber, rubber, and braid. According to the difference of the coil and the actual application, the web guiding application solution can eliminate the position deviation of the coil during the processing process, and ensure that the coil runs accurately and quickly at the specified position, so as to achieve the required accuracy and neatness of the coil during operation.

Components of the automatic web guiding system:
1. Controller,
2. Sensors,
3. Rectifier actuator, actuator generally has many models to choose from, which can be selected according to the actual material and application.

Features of each component of the PRE China Supplier Automatic Guiding System:
Controller: The guiding controller is the core of the guiding system.
1. Support two ways: edge rail and center rail.
2. Support photoelectric sensors, ultrasonic sensors.
3. Intelligent detection of sensor parameters, no need to calibrate the sensor in most environments.
4. Support Modbus and PLC/HMI network control.
5. Adopt FIR digital filter, hysteresis filter, stronger anti-interference ability, more stable signal.
6. Store 10 groups of different material parameters, convenient to switch materials, etc.

Sensors: ultrasonic sensors and photoelectric sensors.

• Ultrasonic sensors:

1. The ultrasonic sensor uses the principle of high-frequency ultrasonic linear propagation to detect the edge position of the coil.
2. It is not suitable for the correction of breathable materials (such as non-woven fabrics, fabrics, etc.).
3. It is not affected by the transparency of the material.
4. The detection range is 5mm, the detection accuracy is 0.1mm, and so on.

• Photoelectric sensors are affected by the transparency of the material.

Rectifier Actuator: Take PD104L-80 Web Aligner Actuator Actuator as an example: Most of the PD-104L80 parts are produced by die-casting, and the use of precision machining has been proved for many years, with easy installation, reliable transmission, stable operation, low wear, long service life, and the product is very mature.
1. Base structure, the vertical direction can be freely moved 15 degrees.
2. Precision ball screws.
3. With limit switch, midpoint switch, etc.

How the automatic trainer works:
An ultrasonic signal is sent by the guiding sensor to monitor the movement of the web and send the signal to the controller. After the controller finds that the coil has position drift, according to the instruction preset by the controller, the correction frame swings through the driver D to correct the position of the coil. The coil automatic deviation correction system uses an ultrasonic sensor to detect the position of the edge of the coil, sends the measured position error signal to the controller, and controls the drive motor to correct the coil with the deviation position to the correct position after the control unit judges and processes.

Characteristics and application fields of automatic deviation correcter:
The automatic deviation correction device has the characteristics of stable work, high precision, sensitive response, durability and simple installation and commissioning, and is widely used in: packaging machinery, printing machinery, label equipment, paper processing equipment, plastic and rubber machinery, textile equipment, metal processing equipment, sanitary products production lines and other emerging industries in the production line.

The role of the guiding control system in the industrial coil production system:

• First of all, the web guiding control system can improve the production quality of the coil. Due to the certain deviation of the coil in the production process, if the deviation cannot be corrected in time, the quality of the coil will be affected, which will affect the entire production process. The web guiding control system can respond quickly and make adjustments to ensure the stable production quality of the coil.
• Secondly, the web guiding control system can improve production efficiency. In the coil production process, if there is a deviation and it needs to be stopped to correct it, this will prolong the production cycle and reduce the production efficiency. The guiding control system can automatically detect and adjust in time without downtime, thus improving production efficiency.
• In addition, the web guiding control system reduces energy consumption and production costs. In the case of web offset, additional energy is required to drive the web back to the correct position, thus wasting a lot of energy. The web guiding control system can be quickly adjusted, avoiding wasting energy, improving production efficiency and reducing production costs.
