邮件分拣系统的PLC组态设计+梯形图

摘要邮件分拣控制系统在社会各个行业得到广泛应用，比如物流配送中心、邮局、码头、仓库等行业。分拣系统能有效提高事业单位各个环节的工作效率。
本文在对自动分拣系统原理足够了解的基础上，根据特定的分拣要求，以西门子PLC为控制核心对材料进行分拣。该分拣系统结合传感器技术、组态监控等技术，可以进行现场控制产品的自动分拣。该系统具有很多特点如自动化程度高、运行稳定、分拣精度高、容易控制。稍加修改本系统即可实现对不同分拣对象的分拣。46266
在完成对本系统的设计之后，进行整体调试。在硬件部分，调试其各部分安装的位置和角度，使其材料物块的运行与传感器安装的角度适合。将硬件各部分的动作幅度进行调试之后，进行软件综合测试，实现分拣系统的全过程。

Abstract Mail sorting control system has been widely used in various sectors of the community, such as logistics and distribution center, post office, terminal, warehouse and other industries.Sorting system can effectively improve the work efficiency of all aspects of the business unit.
In this paper, on the basis of sufficient understanding of the principle of automatic sorting system, according to the specific sorting requirements, MITSUBISHI PLC to control the core of the material sorting.
The sorting system combined with sensor technology, configuration monitoring technology, on-site control of products can be automatically sorted.The system has many features such as high degree of automation, stable operation, high sorting accuracy, easy to control.A little modification of the system can be achieved on different sorting objects sorting.
After the completion of the design of the system, the overall debugging. In the hardware part, the position and angle of each part are debugged, so that the operation of the material block and the angle of the sensor installation are suitable.After debugging the action range of each part of the hardware, the software integrated testing is carried out, and the whole process of the sorting system is realized.
