What Are The Basic Principles Of EPC And CPC Correction Systems

The steel chain phase sensor inspects the edge of the steel chain, and the test results are sent to the microprocessor. The microprocessor measures the error data signal and obtains the relative manipulation data signal. The manipulation data signal is increased by the servo controller and sent to the AC servo The motor drives the intelligent hydraulic reversing valve, the hydraulic reversing valve drives the posture of the hydraulic cylinder, and then drives the deviation correction device or the centering electric actuator to move to maintain the correction device or centering.

The key difference between CPC and EPC depends on the CPC centering automatic control system is to ensure that the steel chain continues to remain in the management center of the production line, so it has two phase sensors, such as the phase sensor in the centering system software on the uncoiler Each is located at the two edge positions of the operating steel chain. In order to achieve the requirements for the edge detection of the steel chain with different total widths, it is equipped with a controller lifting system. The purpose of the automatic control system of the EPC correction device is to ensure that the edges of the tape are neat during unwinding, so it has a phase sensor. For example, the coiler is equipped with a phase sensor located on an edge of the operating steel chain. In addition, depending on the specific manufacturing situation, the system settings of the EPC correction device and the CPC alignment equipment are not easy to be completely consistent.
