The Design Of Web Guide Control

Correction system is used in steel materials, paper, printing, labels, plastic film industry as a corrective to the winding machine of the industrial system. In the winding system of automated production assembly line, often due to all causes lateral deviation reel material, can not keep a straight line running once the coil is not aligned will cause the edge of the work of the follow-up step error, resulting in material waste, or stop work adjustment. For example, in strip, tape, plastic film strip take-up items, unwinding process, pre-roll may be irregular or irregular pieces of stretching, strip tension changes and vibration, and other transmission interference the role of the strip can not keep running straight lines caused by the characteristic sign of deviation from the reference position to form a strip deviation. Therefore, an automatic deviation detection and control system to solve the problem of deviation of the edge strip.Deviation problem for the material, the subject of a corrective design detection and control devices. LCD screen display with 12864 parameters and on this basis, developed a multi-interface operation to achieve correction parameter setting menu with the display and adjust the control on the use of high-performance C8051F340 MCU core as the controller, infrared, ultrasound and CCD sensor as the location sensors to detect the edge of different materials position strip the amount of volume and location of the real-time detection technology to set the reference position compared to the amount of deviation obtained to calculate the switch to control a certain amount of output to the screw DC servo motor, so that corrective stick deviation in the opposite direction toward the road, so as to achieve the purpose of correction.Firstly, the material of the correction system for the overall program design, including: sensor module, data processing module, display input module, motor and other modules. Then, on the basis of the membrane to complete real-time detection and correction deviation function. Finally, the system has been debugged and verified, the results show that the detection and control system is stable, high precision, easy operation, has a certain value.
