Pop-up mail tray stop for conveyor

摘要

A conveying system having a plurality of rotating rollers forming a horizontal drive path for moving articles and at least one pop-up stop for stopping movement of articles in such path. A pair of levers are mounted for rotation about a pivot to move one lever arm of each of the pair of levers above and below the horizontal path and thus move one of the rollers above the path in a position to stop articles on the conveyor. There is a pair of rollers mounted for rotation in the horizontal path on one lever arm of each of pair of levers. A pneumatic actuator is connected to at least one of the levers for moving the pair of levers about the pivot thereby to move one of the rollers to a position above the horizontal path.
