Material correction system is applied to the steel, paper , printing , labels , plastic film industry a winding machine for correction of the industrial control systems . In the working process of the winding machine , if the web edge is not aligned will cause the subsequent step of error , resulting in material waste or downtime adjustment . For example , in the the paper ribbon articles winding and unwinding process , may be due to external interference or web tension changes caused by membrane lateral shift can not maintain a forward pass to see them off , thereby causing the membrane to deviate from the reference position , the formation of membrane deviation . Membrane by a straight line , would soon be restored in case of interference , which requires an automatic correction system to solve the problem of deviation of the membrane edge . This material deviation problem , the design of this project a corrective detection and control device . 12864 LCD display parameters , and on this basis to develop a multi - interface operation menu to achieve the corrective parameter settings display and adjust , using high-performance control C8051F340 microcontroller as the core controller ; software rtx51-tiny mini real operating system as a basis for the design of control software ; infrared, ultrasonic , and the CCD sensor as a position sensor to detect a different material from the web edge position quantity , the amount of real - time detection position and process setting a reference position deviation comparing the amount drawn by the integrated the controller calculates the control amount and output to screw servo DC motor , so that the corrective stick toward the deviation in the opposite direction to the traveling , and thus achieve corrective purposes . The thesis material correction system overall program design , including : sensor module , data processing module, input module , motor drive module . Then, based on the membrane deviation of the real-time detection and correction function . Finally , the system debugging and verification , and the results show that : the sets of automatic correction system stable performance , high detection accuracy , easy to operate , has a certain value .
