摘要
针对目前半自动移栽机作业效率低及控制系统性能不稳定等问题,提出一种整排穴盘苗输送方案,并设计开发了控制系统。采用苗盘位置固定,每次夹取一排钵苗的方式,通过控制取苗机械手的横向和纵向位移,实现钵苗的整排输送。系统采用三菱触摸屏作为上位机,三菱FX3U系列PLC作为核心控制器,通过控制各步进电机和气缸协同工作来完成整排穴盘苗的输送。使用SolidWorks三维软件建立整排穴盘苗输送机构模型,对结构和工作原理进行分析,确定控制需求及电气控制系统。利用GX Works2软件应用SFC语言完成PLC梯形图程序编写,使用GT Designer3软件完成三菱触摸屏界面的绘制和PLC控制程序与界面的连接,完成控制系统的搭建与调试。试验结果表明:实时操作触摸屏可以控制系统的运行,监测机械手运动情况,实现整排穴盘苗的输送。
In view of the low efficiency of the semi-automatic transplanting machine and the unstable performance of the control system. A whole row of tray seedlings transportation scheme was proposed, and the design and development control system was designed.The position of the seedling tray is fixed, and each time a row of seedlings is taken. By controlling the lateral and longitudinal displacement of the seedling manipulator, the whole row of seedlings can be transported.The system uses Mitsubishi touch screen as the host computer, and Mitsubishi FX3 U series PLC as the core controller.Through the control of each stepping motor and the cylinder work together to complete the delivery of the whole row of seedlings.Use SolidWorks 3 D software to build a model of the entire row of seedlings. Analyze the structure and working principle, determine the control requirements, and construct an electrical control system.Use the GX Works2 software to apply the SFC language to complete the PLC ladder program writing.Use GT Designer3 software to complete the drawing of the Mitsubishi touch screen interface and the connection between the PLC control program and the interface.Complete the construction and commissioning of the control system.The test verification shows that the real-time operation of the touch screen can control the operation of the system, monitor the movement of the manipulator, and realize the transportation of the whole row of seedlings.
