Abstract: A set of material automatic sorting experiment system was designed in order to improve the problems of the traditional experimental equipment comprehensive. The sorting system combines many modules such as programmable control, touch screen, sensor, transducer,motor, hydraulics and pneumatics, and it can sort different colors and materials automatically, an use the touch screen to monitor and multi-operate the sorting system. The experimental results show that the automatic sorting system can sort different color and different textural material correctly. The system can be used in many experiments, such as the control experiment of PLC and touch screen, sensor technology experiment, electric motor drive control experiment as well as hydraulic and pneumatic control experimental training, which has met the comprehensive teaching needs of interdisciplinary teaching, for example, electrical mechanical automation.

Key words: material sorting, PLC, touch screen, pneumatic technology
