<p>The invention is a method and device for detecting and rejecting defective cigarettes before entrance thereof into quantitative output channels. The output ports of cigarette splitting grooves are connected with cigarette detecting channels respectively, the cigarette detecting channels cause cigarettes to be arranged in vertical cigarette flows, which are mutually parallel, the number of the vertical cigarette flows is equal to the number of cigarette discharging channels of the corresponding quantitative cigarette output channels, the flow channel of each vertical cigarette flow is provided with a cigarette quality detection device and a pneumatic rejecting mechanism, the cigarettes to be detected are detected and rejected at appropriate pause time, and the cigarettes which pass the detection directly enter the corresponding cigarette discharging channels of the corresponding quantitative cigarette output channels through transversal one-by-one cigarette pushing mechanisms. The invention can reject unqualified cigarettes before these cigarettes enter into the quantitative cigarette output channels, thereby thoroughly avoiding huge waste caused by rejecting the cigarettes in batches.</p> |
