Application of Single-cigarette Rejection Technology in Cigarette Hopper of Cigarette Packer

The loose end cigarette is detected and rejected at the position of packet mandrel in existing cigarette packers,a whole group of cigarettes have to be rejected once a loose end cigarette is detected,which results in material waste and low efficiency.Therefore,a single-cigarette rejecting system was designed,which was composed of major electric control cabinet,man-machine interface screen,working table guard,detector and rejecting mechanism.The detector system was installed in the discharge channels of the cigarette hopper,it detected cigarettes,the defective cigarette was rejected at a rejecting point.The practical application results indicated that the system was stable in running,simple in structure and convenient in operation,with a rejecting rate up to 83.7%.Comparing with traditional packet rejecting system,the new system saved 11205 packets against 5613 thousand packets,the total production in a period of 4 months.
