PLC的分拣控制系统课题论文.docVIP

摘 要 PLC控制是目前工业上最常用的自动化控制方法，由于其控制方便，能够承受恶劣的环境，因此，在工业上优于单片机的控制。PLC将传统的继电器控制技术、计算机技术和通信技术融为一体,专门为工业控制而设计,具有功能强、通用灵活、可靠性高、环境适应性强、编程简单、使用方便以及体积小、重量轻、功耗低等一系列优点,因此在工业上的应用越来越广泛。 本文在对熟悉了自动及分拣系统的原理的基础上，根据一定的分拣要求,对材料分拣进行了以三菱PLC为控制核心，MCGS组态软件为监控软件，设计出材料分拣控制系统的控制系统和监控系统。该材料分拣系统以PLC为主控制器,结合气动装置、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。系统具有自动化程度高、运行稳定、分拣精度高、易控制的特点,对不同的分拣对象,稍加修改本系统即可实现要求。 对本系统完成其设计之后，进行了整体调试。在硬件部分，调试其各部分安装的位置及角度，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，进行了软硬件综合调试，实现材料分拣系统中上料、传送与分拣的全过程。 关键词： 材料分拣 传感器 气动装置 PLC MCGS组态软件 Abstract: PLC control is the most commonly used industrial automation control method, because of its convenient control to withstand an adverse environment, it is better than MCU control in the industrial. PLC traditional relay control technology, computer and communication technologies are integrated specifically for industrial control and design, have strong function, common flexible, high reliability and environmental adaptability, and programming simple, easy to use and small size, light weight, a series of low-power advantages in industrial applications become more extensive. Familiar with the goods in the automatic and sorting system principle foundation, according to certain request to sort the mitsubishi PLC as control core, Mcgs software for monitoring software, the design gives material sorting control system. The transport of goods and materials sorting system mainly by PLC controller, combined with pneumatic device, the sensor technology, configuration and monitoring technology, on-site control product automatic sorting. System has a high degree of automation, stable operation and high precision, easy control sorting based on the features of different sorting object, slightly modifying the system can be realized requirements. After completed its design of the system, executing the overall commissioning. In hardware, testing the installation location and angle of the various parts to make it run the block material and the angle of the sensor suit
