Single pack reject mechanism for cigarette packaging machine and method

摘要

A cigarette packaging machine is provided with a mechanism for rejecting defective cigarette packs of a two pack stack of cigarette packs. A defective top pack of the stack is rejected at a first rejection station by a blast of pressurized air or a pusher bar and a defective bottom pack of the stack is rejected at a second rejection station downstream of the first rejection station by a movable arm which pivots away from a position supporting the stack and then pivots toward the stack to strike the bottom pack and eject it from the stack. A magazine filled with acceptable packs is located downstream of the second rejection station for replacing defective packs ejected from the stack.
