The invention discloses a full-automatic bagged article loading device which comprises a roller conveying line and an automatic racking machine. The left end of the roller conveying line is located below a discharging opening, and power baffles are arranged at an outlet of the discharging opening. The discharging opening is located in the upper end of the left side of a warehouse. A rack is arranged in front of the warehouse. Guide rails are arranged at the top of the rack. Trundles are mounted at the bottom of the automatic racking machine and connected to the guide rails in a clamped manner. The automatic racking machine is in sliding connection with the rack. The full-automatic bagged article loading device is reasonable in structural design; whole equipment automatically works in the whole process during work; manual guard is not needed; work efficiency is greatly improved; and use is safer and more reliable. A computer displayer is adopted in a whole system for operation, PLC programming is adopted, an infrared sensor is adopted in each control region and each joint for collecting signals, and therefore control precision is high, and the time is short; false operation is avoided, and carrying quality and carrying efficiency are improved; and faults can be found and removed in time.
