An airflow‐induced separation method for stacked paper labels is proposed with a stream of compressed air used to jet vertically onto the side of the stacked labels and force constraints applied to the two ends of the labels. Its mechanism is revealed that the viscous force caused by airflow is the main driving force for the initial separation of labels and the vertical force is the main factor for the formation of successive separation channels. Theoretical and experimental analyses are implemented to ensure the effects of airflow velocity, label characteristics, label stress, and other factors on label separation and show that a stable separation gap can be generated with separation efficiency of more than 3600 sheets per minute and reliability of 99.99%. A complete airflow‐induced label separation device is designed, which can be integrated into the existing packaging machine, and the physical feasibility of the stack label separation method is verified by experiments.

提出了一种气流诱导的用于堆叠纸标签的分离方法，该方法是使用压缩空气流垂直喷射到堆叠标签的侧面，并在标签的两端施加力约束。其机理表明，由气流引起的粘性力是标签初始分离的主要驱动力，垂直力是形成连续分离通道的主要因素。进行理论和实验分析以确保气流速度，标签特性，标签应力和其他因素对标签分离的影响，并表明可以产生稳定的分离间隙，分离效率超过每分钟3600张纸，可靠性为99.99 ％。设计了一套完整的气流感应标签分离装置，,提出了一种气流诱导的用于堆叠纸标签的分离方法，该方法是使用压缩空气流垂直喷射到堆叠标签的侧面，并在标签的两端施加力约束。其机理表明，由气流引起的粘性力是标签初始分离的主要驱动力，垂直力是形成连续分离通道的主要因素。进行理论和实验分析以确保气流速度，标签特性，标签应力和其他因素对标签分离的影响，并表明可以产生稳定的分离间隙，分离效率超过每分钟3600张纸，可靠性为99.99 ％。设计了一套完整的气流感应标签分离装置，
