Design of tear-tape detection device based on displacement sensor technology to C600 cellophane paper packager

【目的】为解决成像式小盒拉线检测装置识别拉线缺陷准确率低的缺点。【方法】设计了一种基于位移式传感器技术的C600包装机位移式拉线检测装置,该装置采用位移式传感器检测拉线厚度,将拉线厚度以数字化形式显示,以此判断拉线断残、偏移、折叠等缺陷并对其进行处理,并将不合格烟包剔除。【结果】以武汉卷烟厂模拟拉线缺陷进行测试,结果表明:C600包装机位移式拉线检测装置对卷烟小包拉线缺陷检测准确率达到100%,而C600包装机成像式拉线检测装置仅对小包拉线缺陷进行局部辨识,其中拉线偏移(2 mm)检测准确率为37.5%,拉线折叠缺陷检测准确率为0%。【结论】位移式拉线检测装置检测精度明显高于成像式拉线检测。

[Objective]Aiming at the low accuracy in identifying small box tear-tape by imaging-type tear-tape detection device,a tear-tape detection device based on displacement sensor technology is designed in this study.[Methods]The device uses a displacement sensor to detect the thickness of the tear-tape,and displays the thickness of the tear-tape in a digital form to judge and deal with defects such as broken tear-tape,offset,folding,etc.,so as to reject unqualified cigarette packets.[Results]The test was carried out with simulated tear-tape defects in Wuhan cigarette factory.The results showed that the displacement-type tear-tape detection device of C600 packaging machine can realize 100%accuracy in detecting tear-tape defects of cigarette packet.In contrast,the imaging-type tear-tape detection device recognizes only partial packet tear-tape defects,of which the detection accuracy for tear-tape deviation(2 mm)is 37.5%,and the detection accuracy rate for the teartape folding is 0%.[Conclusion]The detection accuracy of the displacement-type detection accuracy detection device is significantly higher than that of the imaging-type detection accuracy detection device.
