Stacking method of automatic stacker crane

The invention provides a stacking method of an automatic stacker crane. The stacking method comprises the steps that a controller controls a conveying mechanism to convey plates to a shifting fork mechanism; the controller controls the shifting fork mechanism to rotate by a preset angle in a preset direction to stack the plates on a plate supporting mechanism, and then controls the shifting fork mechanism to return to the original position; the controller records the stacking time plus 1 and controls the plate supporting mechanism to descend by a preset height; and after the controller judgesthat the stacking time reaches a first preset time, the plate supporting mechanism is controlled to move the stacked plates out and replace a supporting plate, meanwhile, the controller resets the stacking time, and then the steps are repeated. According to the stacking method, under the control of the controller, the shifting fork mechanism is used for bearing the to-be-stacked plates and then placing the plates on the p
