Condition monitoring of multistage printing presses
Abstract
The main concern in printing quality in multistage presses is doubling. Doubling is caused by
imperfections either within stages (units) or in links connecting different stages,mainly resulting from
machine vibration,gear damage,and excessive run-out. In this paper, we propose new means for printing
quality control via geared system health condition monitoring.
The diagnosis is based on the signals
acquired from inexpensive magnetic pickups. A new technique is developed to monitor the gear rotation
synchronization among different stages in order to isolate possible sources of the doubling problem. A new
approach is proposed to determine the gear run-out. Moreover,gear tooth damage detection is conducted
using the beta kurtosis and the continuous wavelet transform based on the overall residual signal. The beta
kurtosis of original signal average is also shown her

监控系统多级印刷机
摘要
在印刷质量的主要关注的是在多级按加倍。造成加倍
在阶段的缺陷(单位)或链接连接不同阶段,主要是造成的
机械振动、齿轮损伤,过度的实力。在本文中,我们提出的新手段印刷
质量控制系统通过面向健康状况监测。
诊断是基于信号
获得廉价的磁车站。新技术开发监控齿轮转动
同步在不同阶段的可能来源以孤立的二倍的问题。一个新的
算法来确定齿轮。另外,齿损伤检测工作的顺利进行
采用β峭度和连续小波变换为基础的综合残余的信号。这个测试
原始信号的平均峭度也列在这里是有用的检测中过多的齿轮。测试
结果显示来自印刷机方法的可行性。
1。介绍
印刷术的多级是一个复杂而又非常昂贵的设备。它的印刷
率(网络)可以高达700米,每分钟。一个典型的新闻包括5 - 12印刷
阶段(单位)相同,在机械设计。每个单元包括许多辊和缸,哪个
是由一个暴露的齿轮系统坐落在外面的单位。图1 schematically
显示了一个齿轮系统的主要部分的单位。每一个圆圈代表一个刺激或螺旋齿轮。这个
印刷缸,缸是连接到档板,八国集团分别G7。G1是
输入齿轮。在每个单元的所有输入齿轮驱动或者通过一个长轴连接到开车
电机或单独电机在每个阶段。
