Here, the third inductor 1103 may also be a proximity switch. Thereafter, the passenger may place the baggage in the baggage tray 200 and then push the baggage tray 200 from the second predetermined area onto the second rolling carrier 1081.

Further, a fourth sensor 1104 may be further disposed on the rack 105, the fourth sensor 1104 is configured to sense whether the baggage tray 200 moves to the motorized pulley of the second rolling carrier 1081 through the second predetermined area, and if so, a fourth sensing signal is output to the controller, and after receiving the fourth sensing signal, the controller may control the motorized pulley of the second rolling carrier 1081 to rotate, so as to output the baggage tray 200 to the delivery outlet 103. In addition, a fifth sensor 1105 may be further provided, where the fifth sensor 1105 is used to sense whether the baggage tray 200 is completely moved out of the second rolling carrier 1081, and if the baggage tray is sensed to be completely moved out, a fifth sensing signal is output to the controller, and the controller may control the motorized roller of the second rolling carrier 1081 to stop rotating after receiving the fifth sensing signal. Here, the fourth sensor 1104 and the fifth sensor 1105 can both be a mirror reflection type photoelectric switch.

With reference to fig. 1 to 11, the continuous baggage tray lifting device 100 according to the present invention includes an input assembly 106, a lifting assembly 107, and an output assembly 108, and the baggage tray 200 is lifted by the cooperation of the input assembly 106, the lifting assembly 107, and the output assembly 108, so that the baggage tray 200 can be continuously and efficiently lifted to a high position for passengers to directly place, and the passengers can directly put the baggage into the baggage tray 200 without a security check personnel recovering and transporting the baggage tray 200, and without the passengers bending over to take the baggage.

Meanwhile, the luggage tray 200 is lifted by the synchronous conveyor belt, the transmission structure is compact in design, the lifting operation can be realized by driving the synchronous conveyor belt through the driving motor 10721, the occupied space is small, the lifting positions are accurate and stable, the noise is low, a plurality of the synchronous conveyor belts can be used side by side, and the security inspection efficiency is improved. In addition, the baggage tray 200 is innovatively conveyed by the meshing conveying method, and the efficient and stable transfer of the baggage tray 200 can be realized in a compact space by matching the tooth-shaped portion 203 provided on the outer bottom wall 202 of the baggage tray 200.

In the present invention, the baggage lifting device 100 may implement lifting control of the baggage lifting device 100 by the following method:

s101: and if the baggage tray is detected to enter the input assembly through the conveying inlet, controlling the first rolling carrying piece to operate so as to convey the baggage tray to a first preset area from the conveying inlet along a first conveying path. Specifically, whether a luggage tray enters the input assembly through the conveying inlet is detected by the first sensor, and if the luggage tray exists, the controller controls the first roller carrier to operate according to the first sensing signal so as to convey the luggage tray to the first preset area.

S102: and if the baggage tray exists on the first preset area, controlling the lifting driving piece to drive the carrying supporting plate on the conveyor belt piece to support the baggage tray to lift the baggage tray on the first preset area to a second preset area at a preset height position along a lifting path. Specifically, whether a luggage tray exists on the first preset area or not is detected by the second sensor, and if the luggage tray exists on the first preset area, the controller controls the lifting driving piece to drive the conveyor belt piece to operate according to the second sensing signal, so that the carrying supporting plate on the lifting driving piece supports the luggage tray and lifts the luggage tray to the second preset area.

S103: and controlling the second rolling carrier to operate to output the luggage tray located on the second preset area position to the conveying outlet along a second conveying path when the luggage tray is detected to move onto the second rolling carrier through the second preset area. Specifically, when the fourth sensor detects that the luggage tray moves to the second rolling carrier through the second preset area, the controller controls the second rolling carrier to operate according to the fourth sensing signal so as to output the luggage tray to the conveying outlet.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
