In this embodiment, the turntable 2 is substantially circular and can cover the whole storage groove, of course, the turntable 2 can also be in other shapes, and when the goods need to be delivered, the turntable 2 can be driven to move the goods in the direction close to the goods outlet 3 until the plate-shaped goods delivery sensing side of the infrared sensor is pressed down, the blocking piece blocks the opposite infrared wave of the goods delivery sensor to generate a closing signal, which indicates that the goods delivery sensor 31 detects that the turntable 2 delivers the goods to the position to be delivered; the main controller receives the signal, controls the turntable motor 4 to stop rotating, stops the turntable motor 4 and simultaneously opens the cargo outlet door motor 5, detects that the cargo outlet door 51 is completely opened by the cargo outlet door sensor 52 arranged at the completely opened side of the cargo outlet door 51 and then sends the signal to the main controller, the main controller sends a command of stopping the cargo outlet door motor 5, simultaneously opens the push rod motor 6 to control the push rod 61 to push out the required cargo to the outside of the cargo outlet door 51, and when the push rod sensor 62 arranged at the completely pushed-out position of the push rod 61 detects that the push rod 61 is completely pushed out, stops the push rod motor 6 and feeds back cargo outlet success information to the main controller. Slightly delaying, after the main controller receives the success signal and receives a feedback signal of successful delivery, the main controller uploads information to an upper computer, the remaining quantity of the goods of the upper computer is reduced by one, and the main controller starts the push rod motor 6 again to execute the operation of withdrawing the push rod 61; when the push rod sensor 62 arranged at the fully retracted position detects that the push rod 61 is fully retracted, the push rod sensor 62 feeds back a signal to the main controller; after receiving the feedback signal of the push rod sensor 62, the main controller starts the cargo compartment door motor 5 to execute the operation of closing the cargo compartment door 51; when the hatch door sensor 52 disposed at the fully closed position of the hatch door 51 detects that the hatch door 51 is closed, the hatch door sensor 52 feeds back a signal to the main controller. The host controller then waits for the next instruction operation. Thus, a complete shipment process is completed.
