1、- 1 - 基于基于 PLCPLC 的传送带机械手控制系统设计的传送带机械手控制系统设计 摘摘 要要 工业机械手传送带系统是流水线自动化生产的重要组成部分，它完成了物件的运 送、抓取、转移等功能是大规模集成控制系统的基础工作单元。在以前的控制系统中， 大多数是用继电器做为开关量控制，自动化程度低，效率损耗较大，已经不能适应目前 的生产需要。 该控制系统采用可编程控制器为核心，通过对信号的采集、处理、输出一系列的集 中控制，使生产更安全稳定高效。设计中完成了硬件和软件的设计。实现了传感器、变 频器、机械手等硬件的调配控制，实现传送带自动减速，机械手抓放等功能。 PLC 作为控制核心的使用比原有的
2、系统控制性更强，应变更灵活，操作更简单，使 系统拥有可靠性高，稳定性好、抗干扰能力强，维护方便等众多优点，为安全高效的工 业生产提供了更好的硬件环境。 关键词关键词：机械手传送带；PLC；继电器；自动控制； - 2 - THE DESIGN OF PLC-based CONTROL CONVEYOR MANIPULATOR SYSTEM Abstract Industrial manipulator conveyor belt assembly line automation system is an important production component, which complete
3、d the delivery of the items, crawls, transfer function is a large-scale integrated control system based on the work unit. In previous control system, the majority is used as a relay switch control, a lower degree of automation, greater efficiency loss, can not meet current production needs. The cont
4、rol system uses a programmable controller as the core, the signal acquisition, processing, the output of a series of centralized control, make the production more efficient security and stability. Completed the design of the hardware and software design. Implementation of sensors, converters, and other hardware manipulator control of the deployment and achieve conveyor brake automatically. Mechanical up grasping functions. PLC as the control over the use of the core of the original contro
