为研究烟支交接系统中蜘蛛手机构抓烟与掉丝之间的关系，基于PROTOS2-2超高速卷接机组烟支交接原理，建立了蜘蛛手机构的解析模型和数值模型，分别计算了蜘蛛手抓烟时吸爪速度、烟支速度及二者的速度差。结果表明：①解析模型和数值模型的计算结果具有较好的一致性。②随生产速度增大，抓烟时吸爪与烟支的速度差逐渐增大，两者呈线性关系。根据计算公式提出了增加行星轮系的基圆半径进而减小速度差的设计方法。③通过抓烟试验，验证了解析模型和数值模型计算分析的正确性，生产速度越高，掉丝现象越严重。

To find out the relationship between spider’s movement and tobacco fallout from cigarette ends in a cigarette transfer system, the analytical model and numerical model of spider mechanism were developed based on the principle of cigarette transfer in PROTOS2-2 cigarette maker, and the movement trajectory, cigarette catching speed and speed difference of suction carriers in spider were calculated separately. The results showed that: 1) The calculation results of analytical model well agreed with those of numerical model. 2) The speed difference between suction carrier and cigarette increased linearly with the increase of production speed. According to the calculation formula, it was proposed to reduce speed difference via enlarging the radius of pitch circle in planetary gear system. 3) The analytical model and numerical model was validated by the test of tobacco fallout, the amount of tobacco fallout positively correlated to production speed.
