[0002] With the increasing passenger throughput in airports, airport service work is also facing tremendous work pressure. Especially in the security inspection process, a large number of trays (or security inspection trays) are used to ensure that the large number of passengers' luggage pieces can be placed in a timely, safe and efficient manner.

[0003] However, further research found that the large-scale use of security pallets cannot guarantee fast and efficient recycling. The traditional recycling method is manual auxiliary recycling processing, and the manual collection of a large number of security pallets is inefficient. Utility Model Content

[0006] Wherein, the spiral mechanism includes a servo motor, a first sprocket, a second sprocket, a chain, a transmission shaft, a gear transmission group and a spiral column corresponding to the gear transmission group; the servo motor is fixed at the bottom position of the frame;

[0007] The output end of the servo motor is provided with a first sprocket; the two ends of the chain are respectively sleeved with the first sprocket and the second sprocket; the second sprocket is arranged on the transmission shaft; the transmission shaft is provided with the gear transmission group, and the gear transmission group is used to drive the spiral column to rotate;

[0008] The spiral columns are at least four groups, two of which are distributed on one side of the frame, and the other two are distributed on the other side of the frame;

[0009] The spiral column comprises a column body and a supporting blade portion extending upward in a spiral along the surface of the column body; the supporting blade portions on the two groups of spiral columns on the same side are used to contact one side edge of the supporting tray, and the supporting blade portions on the two groups of spiral columns on the other side are used to contact the other side edge of the supporting tray;

[0010] The bottom conveying roller machine is arranged below the screw mechanism.

[0011] Furthermore, the frame includes a top rectangular frame formed by a plurality of profiles, a bottom rectangular frame formed by a plurality of profiles, and vertical poles; there are four vertical poles, all of which are arranged between the top rectangular frame and the bottom rectangular frame;

[0012] The entrance enclosed by the inner wall of the top rectangular frame serves as a loading window for placing the tray;

[0013] The supporting blades of the spiral column are all arranged inwardly, and the outer edges of the supporting blades of the spiral column protrude inwardly from the insertion window to form a rectangular edge for supporting the tray dropped from the insertion window.

[0014] Furthermore, it also includes an outer sealing plate; the outer sealing plate is fixedly connected to the two side surfaces of the frame.

[0015] Furthermore, the bottom conveying roller machine includes roller mounting frames and multiple transmission rollers installed on both sides of the bottom of the frame; the two roller mounting frames are transversely installed on both sides of the bottom of the frame, and multiple mounting holes are arranged along the transverse extension direction of the roller mounting frames; the multiple transmission rollers are installed in a transverse arrangement along the roller mounting frames; and both ends of each transmission roller are inserted into the mounting holes of the roller mounting frames.

[0019] Furthermore, along the direction from bottom to top of the column part, the ascending slope of the supporting blade part is smaller (that is, the spiral radius of the supporting blade part is getting smaller and smaller), so that when the top window just contacts, it moves downward slowly, in order to facilitate the slow reception of the placed pallet and ensure the stability of the placement. Then, when the pallet is fully in place, the bottom slope of the supporting blade part is larger, and there is no need to consider stability, which facilitates the subsequent rapid fall and the subsequent rapid transfer of the bottom conveying roller machine.

The frame 20 is mainly composed of aluminum profiles and is used to support the entire device. Similarly, a bottom conveying roller machine 30 is provided at the bottom of the frame 20.

[0046] In specific applications, the servo motor 101 is fixed at the bottom position of the frame 20; the servo motor 101 starts to rotate, and then a first sprocket 102 is installed on the output end of the servo motor 101, and then the first sprocket 102 rotates to drive the chain 104, and then the chain 104 drives the second sprocket 103 installed on the transmission shaft 105; in this way, the transmission shaft rotates and finally drives two groups of spiral columns 107 at the same time. The driving part of the servo motor adopts chain transmission. The spiral mechanism 10 has the function of automatically collecting trays. At the same time, the good synchronization characteristics of the servo motor are used to ensure that the spiral column 107 can easily and quickly drive the tray to move downward from the top window and finally transport it out; under the action of the spiral mechanism 10, the tray slowly falls down, so that when the tray falls down, the bottom conveying roller machine 30 receives the tray, and then transports the tray out of the bagging mechanism;

[0047] Furthermore, the frame 20 includes a top rectangular frame 201 formed by a plurality of profiles, a bottom rectangular frame 202 formed by a plurality of profiles, and vertical poles 203; there are four vertical poles, all of which are arranged between the top rectangular frame and the bottom rectangular frame;

[0053] Furthermore, the outer edge surface of the supporting blade portion 1072 is a smooth surface.

[0054] In the above technical solution, the outer edge surface of the supporting blade portion 1072 is a smooth surface, that is, the smooth surface can be used to smoothly transfer the trays one by one to the bottom of the rack.

[0055] Furthermore, the outer sealing plate 40 is an aluminum alloy plate; and the frame 20 is formed by splicing aluminum alloy profiles.

[0056] Furthermore, the second sprocket 103 is connected to the transmission shaft 105 via a key.

[0057] Furthermore, along the direction from bottom to top of the column part, the ascending slope of the supporting blade part is smaller (that is, the spiral radius of the supporting blade part is getting smaller and smaller), so that when the top window just contacts, it moves downward slowly, in order to facilitate the slow reception of the placed pallet and ensure the stability of the placement. Then, when the pallet is fully in place, the bottom slope of the supporting blade part is larger, and there is no need to consider stability, which facilitates the subsequent rapid fall and the subsequent rapid transfer of the bottom conveying roller machine 30.

[0058] In addition, the top of the spiral column 107 is also designed with a proximity switch to control the start and stop of the mechanism; two pairs of photoelectric beams are used to detect whether the tray enters the bagging mechanism.

[0059] In summary, the tray bagging mechanism provided by the present invention solves the problem of collecting and recycling airport security trays; it also has many technical advantages such as simple structure and low cost, no need for human assistance during the entire process, good safety, high degree of structural integration, and easy maintenance.
