目的 解决BV包装机在生产过程中，容易出现条烟外包透明纸丢失、泡皱、粘贴不牢、反条包装、拉线丢失、拉线错位等外观包装缺陷不能被有效检测及剔除等问题。方法 设计一种新型的BV包装机条烟外观视觉检测系统，通过动态图像采集、图像识别与处理、安装支架设计、工业相机安装、触发脉冲采集、剔除装置设计等，实现对外观存在缺陷条烟的自动准确检测剔除。结果 该外观视觉检测系统实施后，外观缺陷条烟检测和剔除率≥99.8%，误剔率≤0.01%。结论 该外观视觉检测系统能提高产品外观质量，降低物耗，为精益生产、精益加工起到了一定的保障作用，该系统和技术可推广应用于行业内的单机包装设备上。

The work aims to solve the problem that such appearance packaging defects as missing cigarette's exterior transparent paper, bubbles and wrinkles, poor pasting, antifenite packaging, missing tear band, and tear band dislocation can not be effectively detected and eliminated in the production process of BV packaging machine. A new visual detection system for cigarette appearance of BV packaging machine was designed to realize the automatic and accurate detection and elimination of the cigarettes with appearance defects by means of dynamic image collection, image recognition and processing, mounting bracket design, installation of industrial cameras, collection of trigger pulses and design of culling devices. After the implementation of visual detection system, the detection and elimination rate of the appearance defect cigarette was≥99.8%, and the error rate was≤0.01%. The visual detection system can improve the appearance quality of products, reduce the material consumption, and play a certain role in ensuring lean production and lean processing. The system and technology can be applied to all single-machine packaging equipment in the industry.
