目的 为了方便对硬币进行分类、整理和包装，设计一种自动硬币清分打包机。方法 在PLC程序控制下，通过上料机构将硬币筛选分离，然后对分类后的硬币进行计数、换向、打包，打包后的硬币会移动到箱中。结果 设计的自动硬币清分打包机分类准、精度高、速度快，能够区分4个币种，速度可以达到14卷/min。结论 该硬币清分打包机适于在硬币流通量大的机构进行推广应用，有较好的市场前景。

The work aims to design an automatic coin differentiating and wrapping machine in order to classify, sort out and package the coins. Under the control of PLC program, the coins were orderly separated through the feeding mechanism; then, the sorted coins were counted, reversed and wrapped; finally, the wrapped coins would be moved into the packaging boxes. Featured by accurate classification, high precision and high speed, the designed automatic coin differentiating and wrapping ma-chine could distinguish 4 currencies and its speed could reach 14 volumes/min. The proposed machine is suitable for the wide-spread use in the agencies with large coin circulation and has better market prospect.
