When the motor 5 receives the unstacking signal and starts, the motor 5 drives the first rotating shaft 6 to rotate through the transmission component 7, the first rotating shaft 6 drives the two second rotating shafts 9 to rotate in the reverse direction through the speed reducers 8, the second rotating shafts 9 drive the ratchets 10 to rotate by a certain angle, the first external teeth of the ratchets 10 are separated from the lowermost luggage tray 15, so that the lowermost luggage tray 15 falls onto the tray output mechanism 3. At the same time, the second external teeth of the ratchets 10 just catch the next luggage tray 15, and the luggage tray 15 that falls onto the tray output mechanism 3 is output by the tray output mechanism 3, completing the return flow of the luggage tray 15.

[0027] Through the cooperation of the inner shell, the tray output mechanism, the input roller, the motor, the first rotating shaft, the transmission component, the speed reducer, the second rotating shaft and the ratchet, the above technical solution can realize the automatic unstacking and stacking operation of the luggage tray, thereby not only effectively improving the work efficiency, greatly shortening the time for unstacking and stacking the luggage tray, but also reducing the manual participation, lowering the labor intensity of the staff, and at the same time improving the accuracy and stability of the unstacking and stacking operation of the luggage tray. The whole unstacking and stacking machine has a simple structure and is convenient to operate.

[0030] In this embodiment, two first bearing supports 16 are provided on the front side of the frame 1; the first rotating shaft 6 is rotatably connected to the two first bearing supports 16 through bearings; two second bearing supports 17 are provided on both the left and right sides of the frame 1; the second rotating shaft 9 is rotatably connected to the corresponding second bearing supports 17 through bearings.

[0031] In this embodiment, the number of ratchets 10 on each second rotating shaft 9 is two; the ratchets 10 on the two second rotating shafts 9 are arranged in one-to-one correspondence.

[0032] In this embodiment, a first position sensor 11 corresponding to the ratchet 10 is provided on the frame 1, for detecting whether the external teeth of the ratchet 10 rotate in place.

[0033] In this embodiment, the number of the first position sensors 11 is two; the two first position sensors 11 are symmetrically arranged on the left and right sides of the frame 1.

[0034] In this embodiment, a plurality of second position sensors 12 are provided on the outer surface of the inner shell 2 in the vertical direction, for detecting the number of the luggage trays 15 entering the inner shell 2; during use, when the uppermost second position sensor 12 receives a signal, no more luggage trays 15 are input.

[0035] In this embodiment, the tray output mechanism 3 includes an output roller 301, two driven rollers 302, two roller brackets 303, a multi-wedge belt 304 and a plurality of O-shaped belts 305; the two roller brackets 303 are symmetrically arranged on the bottom of the frame 1 from left to right; the output roller 301 and the two driven rollers 302 are arranged side by side in sequence from front to back between the two roller brackets 303; the output roller 301 is connected to one driven roller 302 through the multi-wedge belt 304; the two driven rollers 302 are connected through a plurality of O-shaped belts 305; during use, the output roller 301 drives one driven roller 302 to rotate through the multi-wedge belt 304, and this driven roller 302 drives the other driven roller 302 to rotate through the O-shaped belt 305, so as to convey the luggage tray 15 falling on the O-shaped belt 305.

[0036] In this embodiment, a third position sensor 13 is provided on the roller bracket 303, for detecting whether the luggage tray 15 falls on the O-shaped belt 305; when the third position sensor 13 detects that the luggage tray 15 is in place, it sends a signal, and the output roller 301 starts to act, driving the driven roller 302 and the O-shaped belt 305 to convey the luggage tray 15 in the output direction, completing the return of the luggage tray.

[0037] In this embodiment, both the input roller 4 and the output roller 301 are electric rollers.

[0038] In this embodiment, the reducer 8 is a worm and worm gear reducer.

[0039] In this embodiment, a casing 14 is provided outside the rack 1, which can play a protective role.

[0040] In this embodiment, the ratchet pallet unstacker is further provided with a control system. During use, the control system controls the motor 5, the input roller 4, and the output roller 301 to act according to the preset program and the information fed back by the sensors, so as to complete the pallet unstacking and stacking operations.

[0041] Working principle: The empty luggage pallet 15 is driven by the input roller 4 into the inner shell 2 to achieve empty pallet stacking. During this process, the number of luggage pallets 15 inside the inner shell 2 can be known through the second position sensor 12 on the inner shell 2. When the uppermost second position sensor 12 receives a signal, no more luggage pallets 15 are input. At this time, the lowermost luggage pallet 15 is supported by the first outer teeth of the four ratchets 10. When the motor 5 receives the unstacking signal, it can act. The motor 5 drives the two second rotating shafts 9 to rotate a certain angle through the transmission assembly 7, the first rotating shaft 6, and the reducer 8. During this process, the rotation directions of the two second rotating shafts 9 are opposite. When the first position sensor 11 detects that the second outer teeth of the ratchet 10 reach the position, the stacking height of the adjacent luggage pallets is the same as the arc distance between the adjacent two outer teeth of the ratchet 10, so that the second outer teeth of the four ratchets 10 just connect to the luggage pallet 15. At the same time, after the ratchet 10 rotates, the first outer teeth of the ratchet 10 disengage from the lowermost luggage pallet 15, so that the lowermost luggage pallet 15 falls onto the O-shaped belt 305 of the lower pallet output mechanism 3. The third position sensor 13 detects that the pallet is in place, drives the driven roller 302 to rotate through the output roller 301, and the driven roller 302 drives the O-shaped belt 305 to move, driving the luggage pallet 15 to be conveyed in the output direction to complete the return of the luggage pallet.

[0042] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
