宽幅纸张定量、水分和厚度等参数的横向差成为造纸企业越来越关心的问题,本文介绍了一种基于西门子PLC的扫描架高精度定位方案,成功解决了扫描架的精确定位和横向检测点与横向控制点之间精确对应的问题,为QCS系统准确检测纸张横幅数据及纸张横向控制奠定了可靠的技术基础。
This paper introduces a high precision positioning scheme of gantry based on Siemens PLC, which successfully solved the problem of precise positioning and lateral detection of gantry The precise correspondence between points and horizontal control points has laid a solid technical foundation for the QCS system to accurately detect the paper banner data and the horizontal control of the paper.
