Description

Technical Field

[0001] This utility model relates to the technical field of parcel security inspection, and in particular to a sorting system with security inspection function. Background Technology

[0002] In freight transport and logistics operations such as railways, highways, waterways, and air transport, as well as postal and express delivery services, a security inspection system must be implemented. In accordance with regulations, transported and delivered items must be inspected or opened for inspection in order to screen out prohibited items and eliminate potential safety hazards.

[0003] In existing technologies, parcel security checks are independent processes, and the security inspection devices are also independent devices including conveyor belts. Parcels need to be transported onto the conveyor belt, and then pass through the security inspection device to complete the security check before sorting. However, in pursuit of efficiency, courier companies have not fully implemented their security inspection responsibilities. There are instances where parcels are not inspected at all, and multiple parcels are bundled together for inspection, rendering the security checks merely a formality. If parcels contain firearms, ammunition, controlled knives, flammable and explosive hazardous materials, corrosive and radioactive materials, drugs, biological samples, etc., and are transmitted via courier, it will pose a significant security risk. In particular, malicious individuals sending biological samples or exotic species via cross-border courier services could pose a national security threat to some extent. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a sorting system with security inspection function to solve the technical problems of low security inspection efficiency and perfunctory security inspection of packages in the prior art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] In a first aspect, this utility model provides a sorting system with security inspection function, including a security inspection device and a sorting transport line. The sorting transport line is sequentially formed with a loading section, a security inspection section, and a sorting section. The security inspection device is positioned corresponding to the security inspection section. The sorting transport line includes a compartment corresponding to the sorting section and used to receive packages. The security inspection device is adapted to scan packages. When the security inspection device detects prohibited items, the sorting transport line can sort the corresponding package to the prohibited items compartment. The sorting transport line includes several sorting units connected end to end. Each sorting unit includes a sorting platform for sorting packages.

[0009] (III) Beneficial Effects

[0010] The beneficial effects of this utility model are as follows: This utility model's sorting system with security inspection function integrates express sorting and security inspection functions. The sorting and transportation line is divided into three functional sections: the loading section, the security inspection section, and the sorting section. The security inspection device is precisely matched with the security inspection section, and can perform real-time penetrating scanning and identification of prohibited items on passing packages. Therefore, the installation of the security inspection device has almost no impact on the express sorting efficiency.

[0011] Furthermore, by integrating security inspection devices with sorting and transportation lines, each package is handled independently when passing through the security inspection device, thus ensuring that each package is inspected, improving the accuracy of security inspections, optimizing the business processes of express delivery companies, making express delivery security inspections and sorting more efficient and convenient, and saving express delivery companies labor costs.

[0012] Because the sorting platform of the sorting unit is made of non-metallic material, the sorting unit will not affect the security inspection process, ensuring the smooth progress of the security inspection. Attached Figure Description

[0045] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-12This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is for reference. The sorting unit shown in the figure is a cross-belt sorting unit; other sorting unit forms are not shown.

[0046] Example 1:

[0047] Reference Figures 1-12 This utility model provides a sorting system with security inspection function, including a security inspection device 100 and a sorting transport line. The sorting transport line sequentially forms a loading section 200, a security inspection section 300, and a sorting section 400, with the security inspection device 100 corresponding to the security inspection section 300. The sorting transport line includes a parcel receiving compartment corresponding to the sorting section 400. The security inspection device 100 is adapted to scan parcels. When the security inspection device 100 detects contraband, the sorting transport line can switch to the contraband path to sort the corresponding parcel into the contraband compartment. The sorting transport line includes several sorting units I connected end-to-end, and each sorting unit I includes a sorting platform 3 for sorting parcels.

[0048] In this embodiment, the sorting and transport line is divided into three functional sections: the loading section 200, the security inspection section 300, and the sorting section 400. The security inspection device 100 corresponds precisely to the security inspection section 300 and can perform real-time penetrating scanning and identification of prohibited items on passing packages. Therefore, the installation of the security inspection device 100 has almost no impact on the efficiency of express delivery sorting.

[0049] When the security inspection device 100 detects prohibited items, the system performs feature comparison on the detection image. When prohibited items such as firearms and flammable and explosive materials are identified, a sorting instruction is triggered. The sorting platform 3 sorts the packages with potential security risks to the prohibited items compartment and notifies the relevant parties. Packages without security risks are still sorted to the designated qualified items compartment, ensuring the reliability of the sorting system.

[0050] Furthermore, the security inspection device 100 can apply multi-faceted scanning technology, specifically three-faced scanning technology, which scans the package comprehensively in three directions: top, bottom, left, right, and front and back, to improve the accuracy of identification.

[0051] This utility model achieves efficient sorting and security inspection of packages by setting the security inspection device 100 on the security inspection section 300 reserved on the sorting and transportation line, which greatly reduces the impact of the security inspection device 100 on the sorting efficiency and ensures the sorting efficiency of packages.

[0052] Specifically, the prohibited item route is the path that a package takes during the process of being sorted to the prohibited item compartment. Correspondingly, there are also qualified item compartments and qualified item routes. Qualified item compartments and prohibited item compartments are independent of each other, and qualified item routes and prohibited item routes may have some overlap.

[0053] More specifically, the contraband compartments can be set up in various categories, such as compartments for firearms and ammunition, controlled knives, flammable and explosive contraband, corrosive and radioactive materials, drugs, and biological samples.

[0054] Example 2:

[0055] Reference Figure 3 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0056] The sorting system also includes a path adjustment system 500, which is connected to the security inspection device 100 and the sorting transport line. The path adjustment system 500 enables the sorting transport line to sort packages to the prohibited items compartment or the qualified items compartment, and can also record the security inspection records of the security inspection device 100.

[0057] In this embodiment, the route adjustment system 500 not only connects the security inspection device 100 and the sorting and transport line, but also serves as the core hub for information interaction, ensuring the efficiency and accuracy of the entire security inspection process. The route adjustment system 500 is designed as an intelligent control center, closely connected to the security inspection device 100 via a high-speed data link, receiving and processing the detection data generated by the security inspection device 100 in real time. Once a contraband item is detected, the route adjustment system 500 immediately activates the corresponding emergency plan, controlling the sorting platform 3 of the sorting and transport line to sort the corresponding package to the contraband compartment. The route adjustment system 500 also undertakes the task of recording and storing security inspection records, ensuring that every security inspection process is traceable. It can record the security inspection time and results for each package in detail, and supports long-term storage and rapid retrieval. This feature is crucial for post-event auditing, legal compliance checks, and security incident tracking investigations. When the security inspection device detects different types of prohibited items, the route adjustment system 500 can not only sort the corresponding package to the corresponding prohibited item compartment after the sorting platform 3 of the sorting and transportation line sorts it, but also generate a security inspection report to notify relevant departments via email, SMS, WeChat and other means.

[0058] To enhance user experience and management convenience, the route adjustment system 500 can also be seamlessly integrated with other information systems, such as Logistics Management System (WMS) and Enterprise Resource Planning (ERP), allowing managers to monitor the status and flow of packages at any time and improve overall operational efficiency.

[0059] Example 3:

[0060] Reference Figures 1-3 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0061] The packages are labeled with a unique tag; the sorting system also includes a scanning device 600, which is adapted to scan the tags.

[0062] In this embodiment, the label can be set as a QR code label or a barcode, and can also be scanned from multiple angles to ensure that each package can be recorded by the scanning device 600.

[0063] Example 4:

[0064] Reference Figure 3 and Figure 4 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0065] The security inspection device 100 includes a first scanning terminal 1001, and the scanning device 600 includes a second scanning terminal 6001.

[0066] The first scanning terminal 1001 is a single-view or multi-view X-ray scanning terminal, and the second scanning terminal 6001 is a QR code or barcode scanning terminal, to complete the scanning of the package and the identification of the package number.

[0067] Example 5:

[0068] Reference Figure 3 and Figure 4 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0069] The first scanning terminal 1001 and the second scanning terminal 6001 can be an integrated structure. By integrating the first scanning terminal 1001 and the second scanning terminal 6001 into one unit, the structural compactness of the layout of the first scanning terminal 1001 and the second scanning terminal 6001 can be improved, as can the assembly convenience of the first scanning terminal 1001 and the second scanning terminal 6001.

[0070] Example 6:

[0071] In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0072] The security inspection device 100 also includes a third scanning terminal, which is configured as one or more of a microwave detector, liquid detector, metal detector, and micro-explosive detector. The third scanning terminal can be located upstream or downstream of the first scanning terminal 1001 to cooperate with the first scanning terminal 1001 to more comprehensively complete the scanning of packages, thereby more comprehensively checking the security and type of packages and improving the security inspection accuracy of the sorting system.

[0073] Example 7:

[0074] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0075] Sorting unit I is configured as one of the following: narrow-belt sorting unit, linear sorting unit, flip-board sorting unit, cross-belt sorting unit, and swing-wheel sorting unit. The sorting transport line also includes track II, along which sorting units I are sequentially connected and capable of running. A support area C is formed on the sorting platform 3, suitable for supporting packages and corresponding to the scanning position of the security inspection device 100. Support area C is made of non-metallic material.

[0076] In this embodiment, a support area C for supporting packages is divided on the sorting unit I, and the scanning position of the security inspection device 100 corresponds to the position of the support area C. In this way, the sorting system can be adapted to more efficient multi-layer sorting machines. Even if the sorting unit I is configured as a vertical multi-layer structure, the security inspection device 100 can reliably complete the scanning of each package, greatly improving security inspection efficiency. By using a non-metallic material for the support area C, interference with the scanning accuracy during X-ray scanning of packages can be avoided.

[0077] Sorting units I are connected sequentially and can run along track II, which can ensure the stability and continuity of the operation of sorting units I, and improve the efficiency and accuracy of package sorting.

[0078] The security inspection section 300 is either the arc section or the upper packaging section 200 of track II, so as to make full use of the space of track II, avoid the security inspection device 100 from encroaching on the straight section position, and improve sorting efficiency.

[0079] Example 8:

[0080] Reference Figure 11 and Figure 12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0081] Sorting unit I can be a single-layer structure or a vertical multi-layer structure, with security inspection devices 100 corresponding one-to-one with sorting unit I. By arranging the security inspection devices 100 in layers and corresponding one-to-one with sorting unit I, the sorting system can be adapted to sorting and transport lines with single-layer or even multi-layer structures, thereby improving the efficiency of package sorting and security inspection.

[0082] Example 9:

[0083] Reference Figure 11 and Figure 12In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0084] When the vertical thickness of the package is less than the first threshold, a clearance channel D is provided on the sorting unit I near track II, and the clearance channel D is located below the corresponding sorting platform 3, so that the corresponding security inspection device 100 can be supported on track II and scan the package on the support area C from bottom to top.

[0085] When the vertical thickness of the package is less than the first threshold, the clearance channel D allows the base portion of sorting unit I to clear the scanning channel of the security inspection device 100. Combined with the non-metallic support area C, this allows the security inspection device 100 to scan the package from bottom to top through the support area C. If sorting unit I is a single-layer structure, there is no need for an additional frame to support the security inspection device 100; it only needs to be supported at a suitable position on track II, greatly improving the structural compactness of the sorting system. Even if sorting unit I is a vertically multi-layer structure, at least the bottommost sorting unit I can be inspected by the security inspection device 100 on track II, further improving structural compactness.

[0086] When the sorting unit has a vertical multi-layer structure and the vertical thickness of the package is less than the first threshold, the upper security inspection device 100 can scan the corresponding package from top to bottom.

[0087] For the upper-level sorting unit I, security inspection can be completed by the security inspection device 100 supported on the gantry. When the vertical thickness of the package is less than the first threshold, the scanning rays can often penetrate the package vertically. At this time, the scanning direction of the upper-level security inspection device 100 can be vertical.

[0088] Specifically, the first threshold is less than 10cm, preferably less than 3cm, to ensure the scanning reliability of the security inspection device 100. By limiting the scanning direction of the security inspection device 100 to vertical, the scanning length can be minimized, saving energy. According to actual measurements, compared with the inclined scanning security inspection device 100, the vertical scanning security inspection device 100 can complete the scan with fewer ends. Combined with its shorter scanning path, the energy consumption of the vertical scanning security inspection device 100 can be reduced to 30% of that of the inclined scanning security inspection device 100. This has significant energy-saving implications for sorting systems that operate for extended periods.

[0089] Example 10:

[0090] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0091] Compared with embodiment 7, the security inspection device 100 may not be supported on track II. Instead, all the security inspection devices 100 may be supported on the gantry and the scanning direction of each group of security inspection devices 100 may be tilted to correspond to the support area C on sorting unit I, so as to improve the consistency of the security inspection devices 100. However, the structural compactness is reduced compared with the previous form.

[0092] In this method, the spacing between the scanning end of the security inspection device 100 and the package can be arranged more flexibly, so it is basically not limited by the vertical height of the package.

[0093] The security inspection device 100 with a tilted scanning direction can be applied to sorting units I with single or multi-layer structures, see reference. Figure 11 The scanning direction.

[0094] Example 11:

[0095] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0096] When sorting unit I is a linear sorting unit, a cross-belt sorting unit, or a narrow belt sorting unit, sorting platform 3 is a belt roller assembly. The belt roller assembly includes two rollers 31 and an annular belt 32 that links the two rollers 31 and has a flat top surface. The annular belt 32 is made of non-metallic material.

[0097] In this embodiment, a support area C is formed on the top surface of the annular belt 32. By making the annular belt 32 a non-metallic material, it is possible to avoid affecting the X-ray scanning results, thereby ensuring the accuracy of security checks and also helping to reduce the overall weight of the annular belt 32. The top surface of the annular belt 32 forms the support area C.

[0098] When sorting unit I is a flip-plate sorting unit, sorting platform 3 is a flip-plate. The flip-plate is made of non-metallic material, such as plastic. The top surface of the flip-plate is the support area C, which can prevent the flip-plate from affecting the X-ray scanning results, thereby ensuring the accuracy of security inspection, and also helps to reduce the preparation weight of the flip-plate.

[0099] When the sorting unit is a balance wheel type sorting unit, the sorting platform 3 is the top cross-section of the balance wheel assembly, and the platform supporting the balance wheel, as well as the balance wheel itself, should be made of non-metallic material to avoid affecting the X-ray scanning results.

[0100] Example 12:

[0101] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0102] When sorting unit I is a linear sorting unit, a narrow belt sorting unit, or a cross belt sorting unit, the vertical projections of the two rollers 31 are both located within the support area C, and the two rollers 31 are made of non-metallic material.

[0103] Sorting unit I also includes a power unit. The input end of the power unit is in contact with track II to convert the relative motion between the input end and track II into input power for the power unit. The output end of the power unit is driven to at least one rotating roller 31 to drive the rotating roller 31 to rotate axially.

[0104] In this embodiment, when selecting a linear sorting unit, a cross-belt sorting unit, or a narrow-belt sorting unit, the sorting platform 3 employs a belt roller assembly. The belt roller assembly includes two rollers 31 and an annular belt 32 surrounding these two rollers 31. The top surface of this belt is flat and forms a support area C, ensuring stable support for anything wrapped around it. Both rollers 31 and the annular belt 32 are made of non-metallic materials to prevent the annular belt 32 from blocking X-rays and to reduce the overall weight of the belt roller assembly.

[0105] In addition, the sorting and transport line also includes track II. Each sorting unit I can run on track II, allowing for flexible adjustment of the number and layout of sorting units I according to actual needs. The output end of the power unit is connected to at least one roller 31, thereby driving the roller 31 to rotate axially, ensuring that packages can move smoothly on the belt roller assembly and complete the sorting process.

[0106] By utilizing the relative motion on track II to drive sorting unit I, the dependence on external power supply is reduced, the independence and reliability of the system are improved, and it can also replace the traditional electric roller drive belt technology, ensuring that the electric roller can be made of non-metallic materials.

[0107] More specifically, when sorting unit I is configured as a cross-belt sorting unit I, sorting unit I can move along its own length direction. Sorting unit I includes a frame 1, a clutch 2, and a sorting platform 3. The sorting platform 3 is rotatably mounted on the frame 1. A first assembly cavity A with an open lower side is formed between the frame 1 and the sorting platform 3. The clutch 2 is located in the first assembly cavity A so that the clutch 2 is embedded in the outline of the frame 1. Sorting unit I also includes a first rotating shaft 4. The first rotating shaft 4 is rotatably connected to the frame 1 and extends along the width direction of sorting unit I and extends to the first assembly cavity A. The first assembly cavity A is arranged along the axial direction of the first rotating shaft 4, and the axial direction of the first rotating shaft 4 extends along the width direction of sorting unit I.

[0108] Length direction Figure 8 The X direction and the width direction are... Figure 8 The Y-direction and the height direction are... Figure 8The Z direction in the equation.

[0109] In this embodiment, a first assembly cavity A is formed between the frame 1 and the sorting platform 3. The first assembly cavity A can effectively protect the clutch 2 and will not affect the normal operation of the clutch 2.

[0110] It is precisely because of the setting of this first assembly cavity A that the clutch 2 can be embedded within the outline of the frame 1, so the clutch 2 will not affect the height layout of the frame 1.

[0111] Meanwhile, the opening on one side of the first assembly cavity A is covered by the sorting platform 3. The sorting platform 3 itself has a requirement for its extension length along the width direction of the sorting unit I. Therefore, even if the setting of the first assembly cavity A and the clutch 2 causes the size of the frame 1 along the width direction of the sorting unit I to increase, it will not protrude from the vertical projection outline of the sorting platform 3. Therefore, the clutch 2 will not affect the overall layout of the sorting unit I.

[0112] Since the first assembly cavity A is embedded within the outline of the frame 1, and the sorting unit I is cleverly used as a component of the first assembly cavity A, the clutch 2, after assembly, will not encroach on the space in the width direction, the height direction, or the length direction of the sorting unit I. Therefore, the sorting unit I will not appear bulky, which is conducive to improving the structural compactness and aesthetics of the sorting unit I. Furthermore, it will not affect the upper packaging platform and lower packaging compartment of the sorting unit I, and thus will not reduce the utilization rate of the space where the sorting unit I is located.

[0113] In this embodiment, the frame 1 includes a main frame 101, a first connector 102, a second connector 103, and a third connector 104. The first connector 102 and the third connector 104 both extend along the width direction of the sorting unit I and are both connected to the main frame 101. The second connector 103 extends along the length direction of the main frame 101 and connects the first connector 102 and the third connector 104. The first connector 102, the second connector 103, the third connector 104, and the main frame 101 form a frame. The sorting platform 3 covers the top opening of the frame to form a first assembly cavity A. The first rotating shaft 4 is rotatably connected to the main frame 101.

[0114] In this embodiment, the first connector 102, the second connector 103, the third connector 104 and the main frame 101 together form a frame-like structure. The top of the frame is covered by the sorting platform 3 to form the first assembly cavity A. This arrangement can ensure that the frame 1 does not have any extra unnecessary components while forming the first assembly cavity A, which is beneficial to reducing the overall weight of the frame 1 and thus to achieving the lightweighting of the sorting unit I.

[0115] Specifically, the main frame 101 can be configured as a rectangular shell to facilitate the installation of the first rotating shaft 4. The first connecting member 102 and the second connecting member 103 can be configured as plates. The third connecting member 104 can be configured as a rod connected to the main frame 101. Multiple rods form one side wall of the first assembly cavity A.

[0116] In this embodiment, the sorting unit I further includes a first drive wheel 5 connected to both ends of the first rotating shaft 4, and a second rotating shaft 6 rotatably connected to the frame 1 and coaxial with the first rotating shaft 4. The first drive wheel 5 can support the frame 1 by supporting the first rotating shaft 4. The clutch 2 includes a torque input part 21, a support part 22, and a torque output part. The torque input part 21 is connected to the first rotating shaft 4 or the first drive wheel 5, the support part 22 is connected to the frame 1, and the torque output part is connected to the second rotating shaft 6. The clutch 2 can disconnect or engage the drive connection between the first rotating shaft 4 and the second rotating shaft 6. The second rotating shaft 6 maintains a drive connection with the sorting platform 3.

[0117] The power unit includes the first drive wheel 5, the first rotating shaft 4, the clutch 2, and the second rotating shaft 6. The input end of the power unit is the first drive wheel 5, which inputs power to the power unit through friction with the track II. The output end of the power unit is the second rotating shaft 6, which establishes a driving connection with the rotating roller 31 through the gear assembly and the chain assembly.

[0118] In this embodiment, the first rotating shaft 4 can serve as the support shaft of the frame 1. The first drive wheel 5 can be rotated by friction when the sorting unit I is running. Since the torque input part 21 of the clutch 2 is connected to the first rotating shaft 4 or the first drive wheel 5, and the first rotating shaft 4 serves as the load-bearing shaft, the first rotating shaft 4 is allowed to bear a larger torque. When the load of the sorting platform 3 is large, the first rotating shaft 4 will not deform, and the clutch 2 can still maintain reliable and stable operation.

[0119] The support part 22 is supported on the frame 1. If it is supported on the second connector 103, a groove can be opened on the plate-shaped second connector 103 so that the support part 22 is connected to the groove.

[0120] This technical solution integrates the load-bearing shaft of sorting unit I and the torque input shaft of clutch 2 into the first rotating shaft 4, thus further improving the structural compactness of sorting unit I and reducing the overall cost of sorting unit I.

[0121] The second rotating shaft 6 can be rotatably connected to the second connecting member 103. The clutch 2 is used to disconnect or engage the drive connection between the first rotating shaft 4 and the second rotating shaft 6. When the clutch 2 is switched to the closed state, the second rotating shaft 6 can operate in conjunction with the first rotating shaft 4, thereby driving the sorting platform 3 to operate. When the clutch 2 is switched to the open state, the torque transmission between the second rotating shaft 6 and the first rotating shaft 4 is disconnected, and the sorting platform 3 will stop operating.

[0122] The second rotating shaft 6 is rotatably connected to the frame 1, and the second rotating shaft 6 maintains a drive connection with the sorting platform 3; the clutch 2 can switch between an engaged state that establishes a drive connection between the first rotating shaft 4 and the second rotating shaft 6, and a disengaged state that disconnects the drive connection between the first rotating shaft 4 and the second rotating shaft 6, thereby enabling the sorting platform 3 to operate or stop operating.

[0123] By controlling the timing and duration of clutch 2, the operating status of sorting platform 3 can be controlled.

[0124] Sorting unit I also includes casters 8, which are vertically hinged to the frame 1 and can support the frame 1.

[0125] In this embodiment, the sorting unit I can be supported not only by the first drive wheel 5, but also by the caster 8. The two can be configured to provide support at the same time, or the sorting unit I can be supported by the first drive wheel 5 in the sorting area and by the caster 8 in the non-sorting area of ​​the sorting unit I.

[0126] In this embodiment, the caster 8 is configured to rotate vertically to accommodate the turning conditions of the sorting unit I. In most cases, when the sorting unit I has a sorting requirement, it operates in a straight line. Therefore, by using the form where the first drive wheel 5 contacts the track II to support the sorting unit I when it has an operational requirement, and the caster 8 contacts the track II to support the sorting unit I when it does not have an operational requirement, the wear of the first drive wheel 5 can be reduced and its service life can be increased.

[0127] Specifically, both the first drive wheel 5 and the caster 8 are rubber-coated wheels.

[0128] More specifically, the first drive wheel 5 can be configured as a polylactide-coated wheel, and the caster 8 can be configured as a polyurethane-coated wheel.

[0129] Furthermore, when the sorting and transport line is a linear sorting unit or a cross-belt sorting unit, the sorting unit I also includes a tray 7, which is used to support the top surface of the annular belt 32 below; the tray 7 is made of non-metallic material; or, the tray 7 has a clearance opening B, which corresponds to the vertical projection position of the support area C.

[0130] The pallet 7 can improve the stability of the belt when supporting goods. By setting the pallet 7 to a non-metallic material, such as an acrylic plate, it is possible to avoid affecting the X-ray scanned goods while ensuring its supporting function.

[0131] Alternatively, the vertical projection position of the port B can be aligned with that of the support area C, allowing it to make way for the X-ray scanning position. This would also prevent it from affecting the X-ray scanning of the goods. However, this solution would reduce the support capacity of the pallet 7 for the belt.

[0132] For cross-belt sorting units, the security inspection device 100 can be installed in the middle of the upper layer of track II. Figure 10 and Figure 11 A schematic diagram of the cross-belt sorting unit is shown. Although the cross-belt sorting unit shown in the figure has a double-layer structure, the present invention does not limit the specific structure of the cross-belt sorting unit. In other words, cross-belt sorting units with single-layer or even multi-layer structures using this sorting system are all within the protection scope of this invention.

[0133] Example 13:

[0134] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0135] Compared with Embodiment 12, the difference in this embodiment is that the power component includes a motor and a transmission mechanism. The motor is supported on the sorting unit, and the output end of the motor is driven to at least one rotating roller 31 through the transmission mechanism.

[0136] In this embodiment, the rotating roller 31 is still driven by electric drive. In this solution, the structure of the sorting unit is simpler, while providing sufficient or even greater power, reducing drive delay and improving sorting accuracy.

[0137] Example 14:

[0138] Reference Figures 1-12 In addition to possessing all the technical solutions of the above embodiments, the sorting system of this utility model further possesses the following technical solutions:

[0139] At least one roller 31 is an electric roller, and the vertical projections of both rollers 31 are located outside the support area C.

[0140] In this embodiment, the sorting unit I of the sorting and transport line does not use a power component to drive the non-metallic roller 31, but adopts a traditional electric roller drive. This also avoids the negative impact on the X-ray scanning accuracy by eliminating the influence of the electric roller. Specifically, the vertical projection of the electric roller is excluded from the vertical projection outline of the support area C.

[0141] It can be understood that, except for conflicting parts, the above embodiments 1-14 can be freely combined to form other embodiments of this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0144] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "beneath" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0145] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, articles, or apparatus / devices.

[0146] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
