Edge Guide System

A system consisting of EPC (Edge Positoin Control) and CPC (Center Position Control) enables high-precision control. The system works as shown below. The steel strip position sensor detects the edge of the steel strip, and the detection result is sent to the microcontroller. The microcontroller calculates the deviation signal and gives the corresponding control signal. The control signal is amplified by the servo driver and sent to the servo motor. The motor drives the intelligent commutation. The valve, the reversing valve drives the cylinder to act to drive the rectification or centering actuator movement to achieve rectification or centering.

The main difference between CPC and EPC is that the CPC centering control system is to ensure that the steel strip is always in the center of the production line, so there are two position sensors. For example, in the centering system on the uncoiler, the position sensors are respectively located in the running steel belt. The two edge positions are equipped with a set of sensor moving devices in order to meet the requirements of edge detection of different width steel strips. The purpose of the EPC guide control system is to ensure that the winding edge is neat during winding, so that there is one position sensor. If the coiler is equipped with a position sensor, it is located at one edge of the running steel strip. In addition, depending on the actual production situation, the EPC guide and the system configuration of the CPC centering device will not be exactly the same.
