接装纸涂胶在线检测及剔除系统的设计应用

为实时监测并剔除因接装纸涂胶不均、位置偏移等产生的缺陷烟支,根据接装纸涂胶量对微波电磁场能量参数造成的不同变化,设计了接装纸涂胶在线检测及剔除系统。该系统利用微波介质谐振器振荡器产生的微波信号,通过微波PIN单刀多掷开关将微波信号分时发送到微波谐振腔作为检测信号,根据谐振腔输出信号幅度值的变化可判断出接装纸涂胶质量是否有缺陷。应用效果表明,该系统实现了在线检测并剔除烟支接嘴端、搭口端未涂胶,接装纸涂胶量太少,位置发生偏移的缺陷烟支,检测最小缺胶面积2 mm×2 mm,有效剔除率达到96%,从而保证了接装纸涂胶质量及控制精度,提高了烟支外观质量。

Design and Application of Online Detecting and Rejecting System for Tipping Paper Gluing

In order to real-timely detect and reject the defective cigarettes caused by tipping paper with uneven gluing or misalignment,an online detecting and rejecting system was designed basing on the variations of electromagnetic energy parameter of microwave versus glue amount.The microwave signal generated by a microwave media resonator was time-sharingly sent to a microwave resonant cavity by a single-pole multiple-throw microwave PIN switch.The variation of output signal from the resonant cavity would indicate that whether the tipping paper was properly glued.The application results showed that the system could online detect and reject the cigarettes with tipping paper gluing defects,the smallest detectable area of glue missing was 2 mm × 2 mm,and the effective rejecting rate was up to 96%.The quality of tipping paper gluing was well controlled and appearance quality of cigarette was improved.
