在物流行业高速发展的今天，高度自动化的邮件分拣装置扮演着重要的角色其分拣效率直接影响邮件的配送效率。因此，邮件分拣机技术的提高与完善,有利于邮政自动化事业的发展,对于节省劳动力、提高效率、减少错误率和降低成本等方面都有十分积极的意义。19703
本毕业论文是针对环形分布式邮件分拣机的识别和移送部分进行研究和设计。对于整个邮件分拣装置来说，邮件的识别分类是分拣的前提，之后的移送更是邮件分拣的重要组成部分，其移送速度直接影响到分拣的效率。整个环形分布式邮件分拣机将受到这两部分的重大影响，所以可以说识别和移送是分拣的核心。

Abstract
Ring distributed mail sorting machine is a kind of highly automated sorting device, with the rapid development of logistics industry, the demand for this kind of highly automated sorting device more and more. The support for research in the sorting device is also more and more.
Today, in the rapid development of logistics industry, highly automated sorting device plays an important role in the sorting efficiency directly affect the distribution efficiency of mail. Therefore, mail sorting machine technology to improve and perfect, promoting the development of the postal automation, to save labor, improve efficiency, reduce error rate and reduce the cost and so on has a very positive meaning.
This thesis is aimed at ring distributed mail sorting machine recognition and transfer part of the study and design. For the whole mail sorting device, identify classification is the premise of sorting mail, after the transfer is an important part of sorting, its transfer speed directly affects the efficiency of sorting. The entire ring distributed mail sorting machine will be affected by the two major parts, identification and transfer is the core of sorting, so to speak.
Key words: mail sorting machine; Ring distributed; Automation, identification, transfe
