基于PLC和触摸屏的果蔬自动包装机控制系统设计

Design of Control System for Automatic Fruit and Vegetable Packaging Machine Based on PLC and Touch Screen

目的克服水果、蔬菜手工包装速度慢、包装外观不美观等问题,提升包装机械的自动化水平,降低包装机成本。方法首先介绍果蔬包装机的基本结构和工艺流程,并在此基础上提出一种以可编程控制器(PLC)和触摸屏为核心的果蔬全自动包装机控制系统,并详细论述基于PLC和触摸屏的硬件结构。在硬件结构基础上,针对该包装机工艺流程开发与之配套的软件系统。结果该控制系统结构简单、操作简单、可编程性强,能够完全满足自动包装机的运动控制要求。结论该控制系统具有较高的可靠性和可维护性,显著提高了果蔬包装效率,提升了包装机的智能化和自动化水平。

The work aims to overcome the slow manual packaging speed and inaesthetic packaging appearance of fruits and vegetables, so as to improve the automation level of the packaging machinery and reduce the packaging machine cost. Firstly, the basic structure and technological process of the fruit and vegetable packaging machine were introduced. Based on that, an automatic fruit and vegetable packaging machine control system focusing on programmable controller（PLC） and touch screen was put forward, and the hardware structure based on PLC and touch screen was discussed in detail. Meanwhile, based on the hardware structure, the software system supporting the packaging machine with respect to its technological process was developed. The control system was simple, easy-to-operate and programmable, and could fully meet the movement control requirements of the automatic packaging machine. With higher reliability and maintainability, the control system significantly improves the packaging efficiency of fruits and vegetables, and the intelligence and automation level of packaging machine.
