摘要
    随着科学技术的飞速发展，各行各业都已不同程度的步入了机械化时代。而传统的人操纵机械已逐步被淘汰，取而代之的是科技含量高的自动化，机电一体化。水果自动分拣系统是一中集机械传动，图像处理，PLC电路控制的机电结合的现代化设备。目前，对于一些体积小重量轻的水果一般采用气动分拣。它主要可分为水果图象采集段和水果分级段，水果在摄像室内进行图象采集后，图象采集段输出信号给水果分级段，水果分级段的控制件根据信号做出相应的动作控制气泵喷气将符合分级标准的水果，吹离输送装置并完成分级。由于气动机构的气体压力可调节，分级操作简单准确成本低，便于推广和使用，且有效减小了机械力对水果的损伤。因此，它必将取代传统的水果分拣系统。

Abstract
  With the rapid development of science and technology, have varying degrees of all walks of life entered the era of mechanization. Whereas the traditional manipulation of machinery has gradually been eliminated, replaced by high-tech automation, electrical and mechanical integration. Automatic fruit sorting system is a set of mechanical transmission, image processing, PLC's mechanical and electrical circuit control combined with the modern equipment. At present, some small and light weight of the fruit generally use pneumatic sorting. It can be divided into image collecting fruits and fruit classification paragraph, fruit indoors in camera after the image acquisition, image acquisition above the output signal to the above classification of fruit, fruit pieces graded in accordance with paragraph control signal to the corresponding action to control air jet would be consistent with the classification standards of fruit, blown off and complete the grading conveyor. Institutions as a result of gas pressure pneumatic adjustable, accurate classification is simple and low cost, ease of dissemination and use of, and effectively reduces mechanical damage to fruit. Therefore, it will replace the traditional fruit sorting system.
