Automatic self-contained stacking machine

摘要: The present invention comprises devices for receiving a plurality of elongated workpieces, automatically raising the forming single layer predetermined number controlling height and width stack, assembling layers workpieces into stack width, supporting positioning during formation. self-contained machine this is designed producing elongate, stackable workpieces. conveying in generally vertical upward direction to an elevated point above surface on which stacking supported. Vertical conveyance work pieces requires use minimum lateral space conducting that operation as opposed armtype hoisting stackers arm extended takes up significant amount space. are at infeeding formation device also provided. area all operations conducted extends from and, known prior art stackers, outer longitudinal edge workpiece stack. Thus, subject includes infed depositing formed layer, both located substantially within above-described area.
