摘要伴随现代物流事业快速发展，包件分拣机作为物流自动化的核心产品，在中国邮政乃至整个国内物流行业中占据重要地位。工程技术人员在不断提高与完善包件分拣机技术，以促进邮政自动化事业的发展，对节省劳动力、提高效率、减少错误率和降低成本等方面都有举足轻重的意义。
    本文着重讨论了对包分机控制信息环节的改造，包括驱动控制系统、小车控制系统、供包机控制系统、主控系统以及信息网络的组成。
    本文主要是研究交叉带式分拣机在高速运行状态下，要实现平稳、迅速的将邮件准确处理，而对智能小车以及供件系统进行了各方面的理论研究，目的解决自动分拣系统中的瓶颈问题，优化供包小车系统运行参数，并相应调整了主控系统的原有设计。
    设计每八个小车为一组是改造交叉带式小车的一部分工作，一个控制箱控制每组车的信息传递；驱动器和步进电机的控制每个小车，实现小车的正反转，以令小车可以准确的上、下包。
原来闲置的动态称配合龙门架的光电管测量包件的重量、体积，改写供包机 PLC 程序，实现格口的自动齐格功能，避免了二次扫描，提高了生产效率。这样的设计丰富了供包机的功能。
除此之外，设计还增加了一些软性设施，增加了中间服务器，使用了标准的 128码，使扫描开拆，上包分拣，齐格封发时时刻刻都在网络中，实时查询所有邮件的信息数据。一切环节都尽量避免了人工录入，节省了人力，减少了错误。
本文在对控制信息系统改造的论述中，简单的对工程中涉及的 PLC 控制器、频器、电机以及部分传输协议等基本概念进行了讲解，最后介绍了软件环境的配置，使整个系统运转正常。

ABSTRACT
    In the days of rapid development of modem logistic，as a hardcore production of Logistic Automation，the automatic sorter occupies an important place of China postal automation. And it can also make sense to saving labor force，increasing efficiency，reducing making mistake and reducing costs.
    Linking with the re-design of automatic sorting system in Shenzhen Postal District Central Bureau，this article emphatically discussed the design of 1inks of automatic sorting machines information，including drive control system， trolley control system，parcel conveyor system，host control system as well as composition of information network.
    In the design of drive control system，the mode of tray – type sorting will mainly replace by the mode of high-speed halved belt sorting which meets the need of new trend of the times to improve the working efficiency. Additionally it has set up the linear motor and the vice-driving equipment to make the overall system more stable.
    In the design of trolley control system，the tray-type trolley will mainly replace by the halved belt trolley. Every eight trolleys will be a group and in each group of vehicles，the information transmission is controlled by a control box. Each trolley can turn and reverse by frequency converter and the 3-phase squirrel cage asynchronous induction motor so that it can be accurately go up and down.
    In the design of the parcel convey or system，it makes full use of the original in active dynamic scales and coordinates with the photo tube on the gantry frame to measure the weight and size of the parcels. It also can automatically achieve the aligning function by rewriting the PLC program for parcel conveyor and improve production efficiency without the second scanning.
In the design of the soft facility, it has increased the intermediate server. It has used the standard 128 code to scan，sort，seal and send the postal materials in the network all the time so that all mails can be found. All link shave avoided the artificial input and this has saved the manpower and reduced the mistake. 扁平件分拣机自动识别和控制系统设计+CAD图纸:http://www.youerw.com/jixie/lunwen_12104.html
