....大、小球分拣传送系统的 PLC 控制设计专业：电气工程及其自动化： 指导老师：摘 要本课程设计主要对 PLC 程序的结构、特点、各器件的性能以及对被公职对象的控制过程进行具体研究，并通过 PLC 来实现对大小球分拣系统的控制，随着工业自动化、机械化进程的加速，自动控制正在逐步取代传统的人工控制，在改善工作人员的工作环境的同时也使生产效率大大提升，为了最大限度的满足被控制对象和生产过程的控制 u。在本课程设计中对于一些原来用继电接触器线路不易实现的要求，试用PLC 后，将很容易实现。在满足控制要求前提下，采用多种控制模式来对被控制对象进行安全可靠的控制操作，使功能更加全面，其中包括手动控制，自动控制模式，使其操作更强，便于企业各类人员操作，另外，该系统的手动控制模式，也使生产设备的检测和维护更加方便。关键字PLC，大小球分拣，机械臂ABSTRACTThecourseisdesignedforPLCprogramstructure,thedeviceperformance as well as on public object control process carries on theconcrete study, and through PLC to realize to the big ball sorting systemcontrol, along with the industrial automation, mechanization process isaccelerated, the automatic control is gradually replacing the traditionalmanual control, in the improvement of work staff working environmentand make the production efficiency is greatly improved, in order tomaximize the meet was the control object and control of the productionprocess U. On the curriculum design for some of the original relay contactorcircuit not easy, try PLC, can be achieved easily. To meet the controlrequirements under the premise, uses many kinds of control mode tocontrol object is safe and reliable control operation, make the functionmore comprehensive, including manual control, automatic control mode,the operation more convenient, different kinds of staff in the enterpriseoperation, in addition, the system of the manual control mode, also make.资料.....the equipment testing and maintenance more convenient.Key Word...
