摘　　要：针对真丝倍捻生产中捻度不匀率控制及设备管理问题,文章提出了一种基于控制图技术的倍捻动态监测及质量控制方法。根据实际倍捻生产设计了锭速均值与锭速变异系数两个监控指标,并对指标进行了变异源、独立性及正态性分析,确定采用I-MR-R三向控制图对指标进行监控。结果表明:控制图可直观、有效地反映设备锭子转速和锭子间锭速不匀率的情况;可从短期和长期两个时间维度,监控预报机台锭速不匀率的小范围变化,监控捻度不匀变异情况;根据指标波动反映出的漂移量和漂移趋势,可为设备维修保养策略制定提供依据。I-MR-R三向控制图可以监控倍捻生产。To address the problem of uneven control of twist and equipment management problems in double twist production of silk,a method for dynamic monitoring of double twist and quality control was proposed based on control chart technology.According to the actual production of double twist,two monitoring indexes of spindle speed mean value and spindle speed variation coefficient were designed.The analysis of the variation source,independence and normality data of the indexes was performed.It was determined to monitor indexes using I-MR-R three-direction control chart.The results showed that the control chart can directly and effectively reflect the rotating speed of spindle and the unevenness of spindle speed between spindles.From two time dimensions,short-term and long-term monitoring of the small-range change of the spindle speed unevenness and twist unevenness variation could be implemented.The drift distance and drift trend reflected by the fluctuation of index data can provide a basis for formulating equipment maintenance strategy.I-MR-R three-way control chart is feasible for monitoring the production of double twist of silk.
