摘要
为提升三元复合滤棒批量生产中的产品质量,设计了一种红外线光电检测系统。该系统主要由红外线光源、光电接收器、数字信号处理器、显示器和控制器组成,通过检测红外线光源穿透滤棒后光辐射的变化,区分复合滤棒不同单元材料及单元之间间隙,对滤棒成型过程中出现的拼接间隙、相位偏移、单元缺失、单元错位等缺陷进行在线检测。该系统应用于ITM SOLARIS复合滤棒成型机组,在线检测4.6万支"常规醋纤+纸质+活性炭"三元复合滤棒,试验结果表明:(1)复合滤棒中常规醋纤单元、纸质单元、活性炭单元及间隙位置,经红外线系统检测后得到的电信号强度分别为254、87、16、580,4个检测器的电信号开关分别为≥363、≤40、40~143、143~363,实现了不同材质的区分和间隙检测;(2)可对拼接间隙≥0.3 mm、相位偏移≥0.3 mm、单元缺失或单元错位的不合格滤棒进行剔除,剔除准确率达到99.8%。该系统实现了复合滤棒高速生产中滤棒质量的在线检测和不合格产品剔除,有效提高了滤棒质量和生产的稳定性。
Abstract： In order to improve the quality of triple filter rods in batch production, an infrared photoelectric detection system was designed, which was composed of infrared light source, photoelectric receptor, digital signal processor, displayer and controller. Via detecting the variations of infrared light passing through the filter rod, the material in different sections of the triple filter rods was distinguished, and the defectives, such as gaps, phase deviation, section missing or out of alignment were detectable. The system was tested on an ITM SOLARIS filter combiner to on-line detect 46 000 triple filter rods of ＂cellulose acetate ＋ paper ＋ active carbon＂. The results showed that： 1） The electric signal intensities detected by the infrared system were 254, 87, 16 and 580, for cellulose acetate, paper, active carbon sections and gap respectively; and the electric signal switches of the respective detectors were defined as 〉~ 363, ~〈 40, 40-143, 143-363 separately. 2） The defective filter rods with gap ~〉 0.3 mm, phase deviation ~〉 0.3 mm, section missing or out of alignment were accurately rejected with the accuracy of 99.8%. The system realizes the on-line detection and rejection of defective triple filter rods, and promotes the stability of filter rod production effectively.
