ABSTRACT:
An ejection mechanism, primarily for use in association with the cigarette hopper of a cigarette packing machine having a vertical channel in which cigarettes may be stacked one above the other and descend intermittently, comprises a pair of support members at a support level higher than the bottom of said channel for supporting end portions of a cigarette in the channel and movable out of the channel to allow said cigarette to fall; sensing means at a level above the support level; an air nozzle at a level below the support level for producing an air-blast to displace a cigarette from the channel; and a valve controlled by the sensing means so that the air-blast operates when the cigarette at the nozzle level has a bad end detected by the sensing means. When the air-blast operates, the presence of support members relieves the cigarette to be displaced from carrying the weight of cigarettes stacked in the channel above the support members and hence permits the air-blast to produce a sufficient displacement.
