Description

Technical Field

[0001] This utility model relates to the field of security inspection equipment, and in particular to a security inspection tray system. Background Technology

[0002] In the current airport security process, trays need to be manually collected and redeployed after use by passengers, forming a one-way, intermittent flow pattern. Traditional manual collection relies on frequent back-and-forth handling by staff, resulting in inefficiency, heavy manpower load, and operational delays. While some existing automated collection systems employ multi-layer transmission mechanisms or robotic arm collaborative grasping solutions, attempting to replace manual operation, they have revealed significant shortcomings: First, the mechanical architecture is complex, integrating multiple transmission modules and independent sorting units, leading to bulky equipment, numerous failure points, and high maintenance costs; second, dynamic sensing capabilities are weak, tray posture recognition is easily affected by environmental interference, foreign object jamming occurs frequently, and system stability is difficult to guarantee; third, the functional closed loop is missing, existing solutions only achieve tray collection and temporary stacking, lacking intelligent scheduling and precise placement modules, and cannot build a complete "use-collection-replacement" automated cycle. In addition, collisions and wear during tray circulation exacerbate equipment wear and tear, further restricting the long-term operational reliability of the system. Overcoming existing technological bottlenecks and designing a streamlined, stable, and fully autonomous closed-loop intelligent recycling system has become a core challenge in improving airport security efficiency and resource management.

[0003] Therefore, how to provide a more reliable and cost-effective security inspection tray system has become a pressing technical problem that the industry needs to solve. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0029] See Figures 1 to 4 The present invention discloses an embodiment of a security inspection tray system, comprising: a frame, a first transmission channel 1 and a second transmission channel 2 disposed on the frame and arranged vertically. In this embodiment, both the first transmission channel 1 and the second transmission channel 2 are drive roller type conveyor channels; in other embodiments, they may also be belt type conveyor channels or other forms of transmission channels.

[0030] The first transmission channel 1 extends along a first direction and includes a starting end and an ending end. A sorting table 4 is provided on the horizontal side of the starting end for baggage sorting by the person being inspected. A lowering device 5 is provided at the ending end. The first transmission channel 1 and the second transmission channel 2 are used to transport baggage frames containing baggage. The first transmission channel 1 is equipped with a security inspection device 3 for inspecting the baggage within the baggage frames. The security inspection device 3 can be any existing security inspection machine, such as an X-ray security inspection machine or a CT security inspection machine, etc., as long as it includes a transmission channel; this invention does not impose any limitations on this.

[0031] The second transmission channel 2 is used to transport luggage frames in the opposite direction to the first transmission channel 1 and extend to the return area 21 below the sorting table 4. The return area 21 has a frame retrieval window 41 facing outward for retrieving the luggage frames. When the person being inspected is conducting a luggage security check, they manually take the luggage frame out of the frame retrieval window 41 and place it on the sorting table 4, then place the luggage in the luggage frame, and then push the luggage frame into the first transmission channel 1.

[0032] The lowering device 5 is located at the end of the first transmission channel 1 and is used to connect to the second transmission channel 2, so as to transfer the luggage frame transported by the first transmission channel 1 to the second transmission channel 2.

[0033] By setting up a first transmission channel 1, a lowering device 5, and a second transmission channel 2, the luggage frames are automatically transported and returned. By setting up a sorting table 4, a return area 21, and a frame retrieval window 41, users can manually retrieve the frames and place them on the sorting table 4 for sorting. This not only better suits users' habits but also provides space for sorting, while reducing equipment complexity and improving reliability.

[0034] Specifically, the lowering device 5 includes: a lowering channel 51, a support plate 52, an insert plate 53, and a push rod 54. The lowering channel 51 accommodates the descent of the luggage frame. The support plate 52 is located within the lowering channel 51 and is configured to be height-adjustable to support the descent of the luggage frame. The insert plates 53 are located on both sides of the lowering channel 51 and are used to insert into the edge of the luggage frame to prevent it from descending further. The push rod 54 is located below the support plate 52 and is configured to reciprocate towards the second transmission channel 2 to insert into the edge of the luggage frame and push it into the second transmission channel 2. When the luggage frame enters the lowering device 5, it is supported by the first transmission channel 1 and enters the lowering channel 51 to be supported by the support plate 52. Subsequent luggage frames are then stacked sequentially. When a luggage frame needs to be returned, the tray 52 descends to a predetermined height. At this time, the insert plate 53 inserts into the edge of the second luggage frame below, causing the luggage frame to continue descending. The first luggage frame below is also driven by the tray 52 to descend until it is parallel to the second transmission channel 2, causing the push rod 54 to insert into the edge of the luggage frame and move towards the second transmission channel 2. After pushing the luggage frame onto the second transmission channel 2, the luggage frame is carried away by the second transmission channel 2. The push rod 54 returns to its initial position, and the tray 52 rises below the second luggage frame, ready to receive the next luggage frame. It can be understood that the tray 52, insert plate 53, and push rod 54 are each driven by a power mechanism that drives them to perform linear reciprocating motion. The aforementioned power mechanism can be any existing power mechanism, which will not be described in detail here.

[0035] In some preferred embodiments, to re-inspect luggage in the luggage racks passing through the security inspection device 3, a third transmission channel 8 is provided parallel to the first transmission channel 1 located after the security inspection device 3. A re-inspection platform 7 is located at the end of the third transmission channel 8. The third transmission channel 8 is used to transport luggage racks loaded with luggage to the re-inspection platform 7 for re-inspection. The re-inspection platform 7 is connected to the lowering device 5 and is used to return the emptied luggage racks after re-inspection to the second transmission channel 2. Furthermore, a roller is provided on the re-inspection platform 7 near the lowering channel 51 to guide the luggage racks into the lowering device 5.

[0036] The system also includes a pushing device 15 for pushing the luggage frame from the first transmission channel 1 into the third transmission channel 8. The pushing device 15 may include a push plate perpendicular to the first transmission channel 1, configured to move towards the third transmission channel 8 to push the luggage frame into the third transmission channel 8. In some preferred embodiments, the pushing device 15 may also employ a conveyor belt on the first transmission channel 1 that moves towards the third transmission channel 8 to push the luggage frame into the third transmission channel 8; such a structure still falls within the protection scope of this utility model. A liftable first baffle 12 is also provided on one side of the pushing device 15 on the first transmission channel 1. When re-inspection of the luggage loaded in the luggage frame is required, the first baffle 12 rises to prevent the luggage frame from moving with the first transmission channel 1, thereby facilitating the pushing device 15 to push the luggage frame into the third transmission channel 8.

[0037] The first transmission channel 1 on the front side of the lowering device 5 is equipped with a liftable second baffle 11. An AI camera 6 is installed above the second baffle 11 to identify whether there is luggage in the passing luggage frame. If there is luggage, the second baffle 11 is raised to prevent the luggage frame from entering the lowering device 5. The second baffle 11 also helps the luggage owner to organize their luggage.

[0038] In some preferred embodiments, first trapezoidal plates 13 are symmetrically provided on both sides of the end of the first transmission channel 1, and the inclined sides of the first trapezoidal plates 13 are arranged facing the inside of the first transmission channel 1 to guide the luggage frame to enter the lowering device 5 in an orderly manner.

[0039] In some preferred embodiments, a second trapezoidal plate 14 is further provided on the front side of the pushing device 15 on the first transmission channel 1. The inclined side of the second trapezoidal plate 14 is arranged facing the inside of the first transmission channel 1 to guide the luggage frame to enter the pushing device 15 in an orderly manner.

[0040] In this embodiment, the sorting tables 4 are arranged in sequence, and correspondingly, the return zones 21 are also arranged in sequence. In other embodiments, those skilled in the art can increase or decrease the number of sorting tables 4 as needed.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
