西门子S7-200可编程序控制器(CPU226)为核心,以昆仑通态TPC7062TX触摸屏为上位机,辅以ABB_ACS350变频器、超声物位传感器、测力传感器、光电传感器、接近开关等控制此小型袋装食品包装

摘  要自德国提出工业4.0以来,世界各地的制造业工厂都以智能制造为发展目标。产品包装作为产品制造的重要一环,也越来越受到重视。但目前我国食品生产企业的包装生产自动化仍处于起始阶段,很多企业还没有达到工业2.0的要求。因为国内人力丰富且设备种类单一,企业都选择雇佣人力或使用进口设备完成产品包装,这无疑会提高整个企业的生产成本,而过高的成本是制造型企业的致命杀手。因此自动化食品包装生产线的研究应用对提高食品生产企业的生命力和竞争力有着深远影响。69242

本文的主要介绍了基于PLC与触摸屏的袋装食品包装生产线控制系统的设计。在初步了解袋装食品包装生产工艺要求后,构建出一个以自动成袋包装机为基础,集上料,称重,包装,喷码,检验功能为一体的小型食品包装生产线。该产线主要由上料机构,称重机构,给料机构,包装机构,检验分选机构,喷码与计数机构组成,本文设计了以PLC为核心,以触摸屏构建人机界面的生产线控制系统对此生产线各部分完成自动控制与实时监控。

该控制系统以西门子S7-200可编程序控制器(CPU226)为核心,以昆仑通态TPC7062TX触摸屏为上位机,辅以ABB_ACS350变频器、超声物位传感器、测力传感器、光电传感器、接近开关等控制此小型袋装食品包装生产线。系统具有自动和手动两种运行模式,自动运行模式下对系统各部分实现联锁控制保障其自动完成各种包装任务。手动模式下可对产线各设备进行点动控制以完成设备调试与故障检查。另外系统可检测产线各部分的故障信号并输出报警。触摸屏作为上位机可对整个系统各部分参数与运行情况进行实时监控,并可对系统参数进行设定,对各机构进行手动调试,并且可以查看报警信息与记录。

最后通过将程序下载到PLC与触摸屏中进行运行调试,运行结果与设计一致,从而证实了系统的可行性,完成了对该生产线控制系统的设计。

The Control System design of Food Packaging Production Line Based on PLC and Touch screen

Abstract

Since German proposed the industry 4.0, manufacturing plants around the world are moving in the direction of intelligent manufacturing development. Product packaging as an important part of product manufacturing, but also more and more attention. However, China's food packaging industry fully automated production is still in the initial stage, many companies do not meet the requirements of industry 2.0. Most food manufacturers are dependent on a lot of manual or the introduction of foreign automatic packaging production line to complete the product packaging, whether it is the purchase of foreign equipment or hire workers need to spend a lot of money, but high labor costs are the leading killer of manufacturing enterprises. So Automation Application food packaging production line to increase food production enterprises vitality and competitiveness has far-reaching implications.

The article introduces the control system of the automatic production line based on PLC and HMI. In a preliminary understanding of bags of food packaging production process requirements, to build mall food packaging production lines, include hoisting material, weighing, packaging, marking, testing functions. The product line is mainly composed of hoisting mechanism, weighing mechanism, feeding mechanism, packaging agencies, inspection agencies sorting, marking and counting bodies, we design PLC as the core, to build man-machine interface touch-screen production line control system each part of this production line to achieve automatic control and real-time monitoring.
