摘要：形状判别实训装置是对两种形状不同的工件进行区分并将工件分别放入指定的工件储存区。用户可以通过控制箱操作设备。当在端工件传送带传输端，该传感器通过检测该工件，那么，传感器的端部来区分之间的工件是圆形或方形，随后取单元螺杆驱动夹持器到位抓取工件，并送到适当滑道。通过这次学习PLC控制用户设备的基本方法，可以控制使用设备控制面板上的模式转盘选择自动/手动操作模式，并且可以设置多种用于实验的附加条件。适应不同层次的学习和人员PLC编程。 PLC控制是最常用的工业自动化控制的方法，因为其易于控制，能承受恶劣的环境，所以比微控制器的控制更好。传统的继电器控制技术、计算机技术和通信技术，专业从事工业控制和设计，功能高、可靠性高、环境适应性强、编程简单、使用方便、体积小、重量轻、低功耗等优点，所以在市场上的应用将得到更广泛的应用。42858

Shape recognition device PLC Control System Design

Abstract: Shape discrimination training device is to distinguish between two different types of workpiece and the workpiece into the specified storage area. The user can operate the device by controlling the box. When at the end of the end of the workpiece conveyor belt transmission, the sensor by detecting the workpiece, then the sensor end to distinguish between the workpiece is round or square, then remove the unit screw driven gripper grasps workpieces in place, and sent to the appropriate slide. The basic method of this study PLC control user equipment can control the mode dial on the device control panel to select automatic / manual operation mode, and can set a variety of additional conditions for the experiment. Adapt to different levels of learning and personnel PLC programming. PLC control is the most commonly used industrial automation control method, because it is easy to control, can withstand the harsh environment, so the industry is better than the control of micro controller. Traditional PLC relay control technology, computer technology and communication technology, combining, designed for industrial control and design, with a strong functional, flexibility, high reliability, environmental adaptability design, simple programming, convenient use, small volume, light weight, low power and a series of advantages, so broader industry applications.
