- 1. An apparatus for automatically stacking steel shapes: which comprises, in combination, an endless conveyor running upwardly-obliquely in the travelling direction at a specific gradient angle with respect to the horizontal plane and driven by driving means for conveying steel shapes transversely placed on said conveyor; an overlap-protecting member disposed above and along said conveyor to form a passage therebetween for permitting steel shapes to pass without being overlapped; a stand-by stop member adapted to project into said passage for stopping said conveyed steel shapes at an intermediate part of said passage and then to retract from said passage for advancing said stopped steel shapes; assorting stop means adapted to project into said passage at a position upstream of said stand-by stop member and then to retract from said passage, said assorting stop means having at least one projecting front head adapted to be firmly engaged with the internal surface of a steel shape, said projecting head being attached as an attachment in a positionally adjustable manner so as to be adjusted when steel shapes of a different size and number are handled, timing of the projection and retraction of said assorting stop means being correlated to timing of the projection and retraction of said stand-by stop member so that upon aligned-stop of a group of steel shapes of a predetermined number by projection of said stand-by stop member said assorting stop means is projected to stop the steel shape just succeeding to said group of steel shapes and said stand-by stop member is retracted to advanced said group of steel shapes, and upon completion of advancement of said group of steel shapes said assorting stop means is retracted and said stand-by stop member is projected; a takeout stop member for stopping temporarily said advanced group of the steel shapes at a take-out position; stacking lifter means disposed at a position downstream from said conveyor; stacking lever means adapted to lift said group of steel shapes stopped by said take-out stop member from said conveyor to a level above said stacking lifter, said lever means being adapted to carry out quick retraction and lowering to its original position after lifting of said group of the steel shapes on the stacking lifter means; and driving means for correlating and synchronously driving said stand-by stop member, assorting stop means take-out stop member, and said stacking lever means so as to repeat their correlated foregoing operations.
