The invention relates to an automatic
stacker crane which is high in
automation degree and stacking efficiency. The
stacker crane comprises a first
conveyor belt, a pocket steering mechanism, a middle
conveyor belt, a transition
conveyor belt, a pair of sliding blanking plates, a pushing plate, a lifting platform, a driving roller
assembly and a downhill roller table, wherein the pocket steering mechanism is arranged at the
tail end of the first conveyor belt and is used for rotating pockets horizontally at an angle of 90 degrees and continuing to convey pockets, the middle conveyor belt is arranged at the rear end of the pocket steering mechanism, the transition conveyor belt is arranged at the rear end of the middle conveyor belt, one of the pair of sliding blanking plates is arranged on a middle platform which is arranged on the right side of the transition conveyor belt, the other one of the pair of sliding blanking plates is arranged on the right side of the middle platform, the pushing plate is arranged on the left side of the transition conveyor belt and is used for pushing pockets on the transition conveyor belt to the middle platform and the pair of sliding blanking plates in succession, the lifting platform is arranged on the lower portion of the pair of sliding blanking plates and is used for arranging a tray, the driving roller
assembly is arranged on the lower portion of the lifting platform and the downhill roller table is arranged on one side of the driving roller
assembly. By the aid of the
stacker crane, packages are grouped in accordance with a preset mode, and the pockets are stacked on the tray in
