ABSTRACT:
An apparatus for automatically stacking steel shapes, preferably, steel angles, comprises an endless conveyor running obliquely towards the traveling direction, a member provided above the conveyor at a proper distance to form a passage, this member serving to prevent steel shapes from overlapping, a stand-by stop lever for keeping steel shapes stopped at an intermediate part of the conveyor, assorting stop levers disposed so as to project from a part of the passage upstream from the stand-by stop lever, a take-out stop member for stopping the steel shapes being conveyed upon retraction of the stand-by stop lever, a stacking lifter located downstream of the conveyor with a certain distance therebetween, a stacking lever for transferring the steel shapes stopped on the conveyor by the take-out stop member to the stacking lifter, a magnet lever for stacking up-side-down the steel shapes on the lifter as the occasion demands, and a guide plate for stacking positively and in order the steel shapes from the lever on the stacking lifter.
