Abstract
Description
Technical Field

[0002] The cigarettes transported in the elevator conveying channel are detected as unqualified by the photon detector and need to be removed from the conveying channel as soon as possible to prevent them from entering the subsequent cigarette packing station. The current rejection mechanism mostly adopts the form of cylinder rejection. After the rejection is completed, the cylinder needs to return to the starting position quickly, but there is a risk of collision with the cigarette support block on the elevator conveying channel during this process.
