Coil materials refer to long-sized continuous materials such as paper, film, sheet, non-woven fabric, metal foil, silk, thread, etc. In the process of uncoiling, technological processing, winding, etc, deviation of the coil materials may occur, due to the deviation of the coil itself or the processing machine. The web guiding control system provides a solution to reduce the occurrence of such situations. The system always tracks the position of the coil material during the production and makes corrections in real-time. It can ensure and improve the quality and efficiency of production.
Working principle of web guiding

The web guiding is to guide the sensor to emit infrared or ultrasonic to monitor the operation of the coil material and send a signal to the controller. After that the controller finds that the web has a positional deviation, according to the preset command by the controller, the controller controls the drive system to swing to correct the web position.

The web guide system uses brushless DC servo motor drive, precision ball screw driv with, compact structure, good mechanical rigidity, low inertia, suitable for high-speed and high-precision web guiding.

The system is composed of a controller, a sensor, an electric driver, and a correction guide mechanism. The sensor detects the edge position of the coil material and reads the deviation between the actual position and the set position, converting the deviation into a voltage signal proportional to it. Then sends this signal to the controller. After the signal is amplified and calibrated by the controller, the signal is output to the electric driver, and the electric driver drives the guide mechanism to perform correction actions according to the magnitude of the input signal to guide the coil material to the preset position.
