【摘要】：随着国内现代化技术的迅猛发展,自动控制技术在制造、物流等行业应用非常广泛,同时市场的竞争越来越激烈,很多企业在生产过程中都应用了各种各样的自动生产线或者进行了生产设备的自动化升级改造。通过应用自动控制技术,从而大大提高了企业的生产效率,减少了人工劳动强度,同时在质量控制方面也得到了明显的改善,企业生产过程控制在很多方面都有了很大的提高,所以研制投入自动化生产线也就成为了现代化生产技术发展的必然趋势之一。物料自动分拣在企业自动化生产线、产品流水装配线上以及自动化立体仓库中被广泛运用。自动分拣与传统手工分拣相比具有效率高差错率低、分拣点多、无人工化作业等优势,自动分拣装置的控制系统是分拣装置的核心。本课题提出一种基于可编程控制器PLC和气动控制的物料自动分拣系统,完成了PLC控制系统、气动控制系统等设计。该自动分拣系统是以三菱FX2N系列的PLC作为控制器件,该系统主要由送料模块、进料搬运模块、物料输送及分拣模块组成。每一个模块都是基于气动装置作为执行单元的小型机电系统,另外在整个系统上还安装了各种传感器,用于提供工件的位置、状态、颜色等信号,通过PLC完成对整个系统模块的控制,并采用触摸屏来作为输入控制工具,实现了对不同材质、不同颜色物料的自动分拣。通过实验运行结果表明,该系统分拣正确率高、运行稳定,且可通过设计更换不同种类的传感器实现对不同物料的自动分拣。
[Abstract]:With the rapid development of modern technology in China, automatic control technology is widely used in manufacturing, logistics and other industries. At the same time, the competition of the market is becoming more and more fierce. Many enterprises have applied various automatic production lines in the process of production or the automatic upgrading and upgrading of production equipment. By applying automatic control technology, Therefore, the production efficiency of the enterprise is greatly improved and the labor intensity is reduced. At the same time, the quality control has also been improved obviously. The production process control of the enterprise has been greatly improved in many aspects. So the development of the automatic production line has become one of the inevitable trends of the development of modern production technology. Dynamic sorting is widely used in enterprise automation production line, product line assembly line and automated warehouse. Compared with traditional manual sorting, automatic sorting has the advantages of high efficiency, low error rate, more sorting point and unmanned operation. The control system of automatic sorting device is the core of the sorting device. The automatic sorting system of programmable controller PLC and pneumatic control material has completed the design of PLC control system and pneumatic control system. The automatic sorting system is based on the PLC of MITSUBISHI FX2N series, which is mainly composed of feed module, feed handling module, material transportation and sorting module. The pneumatic device is a small electromechanical system for the execution unit. In addition, various sensors are installed on the whole system to provide the position, state, color and other signals of the workpiece. The whole system module is controlled by PLC, and the touch screen is used as the input control tool, and the automation of different materials and different color materials is realized. Sorting. The experiment results show that the system has high sorting accuracy and stable operation, and the automatic sorting of different materials can be realized by changing different kinds of sensors.
