基于PLC的定长切割控制系统的误差研究

Research on Errors of Fixed-length Cutting Control System based on PLC

在金属板材、塑料、玻璃等的生产过程中,需要对生产出的纵向运动的板材进行在线横向切割,并且切割是精确定长的,这就要求在对运动板材测量的同时对其进行快速准确的切割。本文描述了定长切割原理,分析了对软管定长切割时产生误差的主要原因,针对产生的误差提出了合理的改进方案,使系统切割精度得到了进一步提高。

In the production of sheet metal, plastics, glass and so on, transverse cutting sheet metal must measure the moving belt meantime cutting, and also meet the fixed-length cutting principle, which require rapid and accurate cutting while measuring moving sheets. The paper analyzed the main reason of causing errors in cutting length of hoses, and put forward reasonable improvement scheme for the errors, which further enhanced the cutting precision of the cutting system.
