The key factors affecting the quality of roller is error roller diameter. In the strength in production for measuring amount is larger, there is error in reading the manual measurement. A PLC control roller diameter sorting system in this paper, through mechanical transmission, sensing and measuring method of roller automatic detection and sorting, sorting efficiency is increased in improving measurement accuracy at the same time. This design through the push rod roller is pushed to the limit block, tungsten probe diameter measurement error, the resulting signals are converted to electrical signals by the analog processing module amplification circuit into PLC,then open the corresponding electromagnetic turning plate, the push rod roller into the separating box different In the material box with oil substances,The buffer used in roller falling process, to ensure the precision roller. Through simulation software to learn, the design scheme is feasible, Can be used to measure the diameter and the sorting roller, through this system can not only save the cost but also can impr
