新型商标纸胶水液位异常报警系统的设计

Design of Abnormal Alarm System for Blank Paper Glue Level

目前烟草行业小包硬盒GDX2包装机中使用的商标纸注胶系统有一个显著的缺陷:当商标纸胶水液位检测器出现故障时,系统不能检测到液位异常,使设备生产出大量的不良产品,造成了极大的浪费。为了解决这个问题,设计了一种新型GDX2商标纸胶水液位异常报警系统。该系统采用小型PLC作为控制器,搭配工业人机界面,便于操作,利用GDX2的商标纸胶水液位信号及烟包计数信号,通过逻辑运算判断GDX2商标纸胶水液位是否异常。模拟测试结果表明该系统对GDX2商标纸胶水液位异常的报警准确率为100%。

A new abnormity alarm system of GDX2trademark paper glue level is designed in this paper.The PLC controller,which is equipped HMI for the convenience of operation.Using glue level signal and packet counting signal of GDX2,the system can determine whether the glue level is abnormal through the logic operation.The simulation results show that the accuracy rate of this system is100%for the GDX2trademark paper glue level abnormal alarm.
