The invention discloses a full-automatic high-position stacking device, and belongs to the technical field of automatic stacking equipment of soft packaging bags. The device is used for automatically settling and stacking the soft packaging bags and structurally comprises a rack, a feeding conveying mechanism, a lifting belt conveying mechanism, a bag pressing conveying mechanism, a reversing conveying mechanism, a grouping and bag pushing mechanism and a tray type stacking mechanism are arranged on the rack in the conveying direction of the soft packaging bags, and the mechanisms are all controlled by a control circuit. The full-automatic high-position stacking device is characterized in that the tray type stacking mechanism comprises a layering and shaping mechanism, a tray lifting mechanism and a tray storage and supply mechanism which are matched with the grouping and bag pushing mechanism, and a bag falling guide mechanism for the soft packaging bags is arranged on the feeding conveying mechanism. Due to the fact that the tray type stacking mechanism and the feeding conveying mechanism are improved, the device has the advantages of being modular in structure, high in automation degree, high in stacking efficiency and low in manufacturing cost, and the soft packaging bag full-automatic stacking needs during production of small and medium-sized enterprises are met.
