[0045] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0046] The features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0047] The following description, in conjunction with the accompanying drawings, illustrates the luggage basket 300 conveying device provided in the embodiments of this application.

[0048] like Figure 1 As shown, this embodiment provides a luggage basket 300 conveying device, including a lifting device 100 and a conveying device 200. For ease of explanation, the height direction of the lifting device is defined as the first direction D1, the arrangement direction of the lifting device 100 and the conveying device 200 is defined as the second direction D2, and the direction that is perpendicular to both the first direction D1 and the second direction D2 is defined as the third direction D3.

[0049] Specifically, such as Figure 2 As shown, the lifting device 100 includes a drive mechanism 110, a transmission mechanism 120, and a support mechanism 130. The drive mechanism 110 is used to drive the transmission mechanism 120 to move, and the transmission mechanism 120 can drive the support mechanism 130 to move up and down along the first direction D1.

[0050] like Figure 2 As shown, the conveying device 200 includes a first conveying mechanism 210, a second conveying mechanism 220, and a pushing mechanism 230. The first conveying mechanism 210 and the second conveying mechanism 220 are arranged at intervals along a first direction D1. The first conveying mechanism 210 is used to convey empty luggage baskets 300, and the second conveying mechanism 220 is used to receive luggage baskets 300.

[0051] like Figure 3As shown, the lifting device 100 has a carrying mechanism 130 including multiple carrying parts. The lifting device 100 has a first station. When the lifting device 100 is in the first station, two of the multiple carrying parts are opposite each other along the first direction D1. The pushing mechanism 230 is used to push the empty luggage basket 300 located in the first conveying mechanism 210 to one of the carrying parts. The second conveying mechanism 220 is used to receive the luggage basket 300 of the other carrying part.

[0052] In this embodiment, the luggage basket 300 conveying device 10 is in use. The lifting device 100 is initially in the first position, where the two support sections can be arranged opposite each other along the first direction D1. The higher support section can be used to place an empty luggage basket 300, allowing passengers to place their belongings into it. The lower support section is positioned at a height corresponding to the first conveying mechanism 210, and the pushing mechanism 230 can push the empty luggage basket 300 to the lower support section. Therefore, the luggage basket 300 conveying device 10 can synchronously perform the loading action by utilizing the time it takes for passengers to remove their belongings. After the user removes their belongings, the transmission mechanism 120 can raise the higher support section to a position corresponding to the second conveying mechanism 220, which can then convey the luggage basket 300 to the next position. Then, the transmission mechanism 120 continues to move, driving the carrying structure back to the first work position. At this time, the carrying part that has risen from the low position to the high position carries the empty luggage basket 300. The carrying part that has returned from the high position to the low position can be reloaded with the empty luggage basket 300 conveyed by the first conveying mechanism 210. This process is repeated to achieve the purpose of continuously supplying luggage baskets 300, shortening the waiting time for passengers and improving security check efficiency.

[0053] It should be noted that the application scenarios of the conveying device 10 provided in this embodiment are not limited to airport security inspection systems, but can also be applied to other scenarios that require workpiece transportation. The conveying device 10 provided in this embodiment can be used not only to transport the luggage basket 300, but also to transport other workpieces to be transported.

[0054] In some embodiments, the first conveying mechanism 210 has a first conveying surface, and when the lifting device 100 is in the first position, the bearing surface of one of the two bearing portions opposite each other along the first direction D1 is flush with or lower than the first conveying surface. That is, the lower bearing portion of the two bearing portions is used to carry the empty luggage basket 300 pushed from the first conveying mechanism 210 by the pushing device. Therefore, making the bearing surface of the lower bearing portion flush with or lower than the first conveying surface helps the empty luggage basket 300 to be smoothly pushed from the first conveying mechanism 210 to the bearing surface.

[0055] Of course, in other embodiments, when the lifting device 100 is in the first position, the bearing surface of the lower bearing part can be slightly higher than the first conveying surface, so as not to affect the smoothness of pushing the luggage basket 300.

[0056] It should be noted that the first conveying mechanism includes multiple drive rollers, and the tangential surfaces at the top of the multiple drive rollers form the first conveying surface of the first conveying mechanism 210.

[0057] Furthermore, in some implementations, such as Figure 2 As shown, the lifting device 100 includes a first frame 140, a drive mechanism 110, and a transmission mechanism 120 disposed on the first frame 140. The first frame 140 includes a sorting table 141, which is equipped with an identity information reading device. When the lifting device 100 is in the first working position, the position of the other of the two supporting parts opposite each other along the first direction D1 is configured such that the top edge of the luggage basket 300 is flush with the sorting table 141. That is, the higher of the two supporting parts is used to lift the empty luggage basket 300 to the position corresponding to the sorting table 141, making it convenient for passengers to put their items into the empty luggage basket 300. When passengers put their items in, they can place backpacks, etc., on the sorting table 141, take out the items from the backpacks, and put them into the empty luggage basket 300. The height of the sorting table 141 makes it easy for passengers to pick up their items.

[0058] Of course, in other embodiments, when the lifting device 100 is in the first position, the top edge of the luggage basket 300 can be slightly higher than the sorting table 141, so as not to affect the passenger from putting items into the empty luggage basket 300.

[0059] Furthermore, in some implementations, such as Figure 2 As shown, to facilitate the smooth delivery of the luggage basket 300 to the second conveying mechanism 220, the lifting device 100 also includes a second station. The drive mechanism 110 drives the transmission mechanism 120 to raise the lifting device 100 from the first station to the second station. The second conveying mechanism 220 includes a second conveying surface. When the lifting device 100 is in the second station, the bearing plane of the bearing portion is higher than or flush with the second conveying surface to deliver the luggage basket 300 to the second conveying surface.

[0060] The following example, using a support mechanism comprising four support sections, illustrates the operation of the lifting device.

[0061] like Figure 3 and Figure 4 As shown, the bearing mechanism 130 includes a first bearing part 131, a second bearing part 132, a third bearing part 133 and a fourth bearing part 134 arranged sequentially between the inner chain 122 and the outer chain 121. The fourth bearing part 134 is adjacent to the first bearing part 131 to achieve a cycle.

[0062] When the lifting mechanism is in the first position, the two supporting parts arranged opposite each other along the first direction D1 are the first supporting part 131 and the second supporting part 132. At this time, the first supporting part 131 is in a high position, and the top edge of the luggage basket it supports is flush with the sorting table 141. The second supporting part 132 is in a low position, and its supporting surface is flush with the first conveying surface of the first conveying mechanism 210. Passengers can take out their items and place them in the luggage basket of the first supporting part 131, and the second supporting part 132 receives the luggage basket conveyed by the first conveying mechanism 210.

[0063] After the passenger retrieves their belongings, the drive unit drives the transmission mechanism 120 to move, lifting the lifting device 100 from the first station to the second station. At this time, the bearing surface of the first bearing part 131 is flush with the second bearing surface of the second conveying mechanism 220. As the transmission mechanism 120 drives the first bearing part 131 to move, the speed direction of the first bearing part 131 at the highest position is towards the second conveying mechanism 220. Therefore, the luggage basket can be sent to the second conveying mechanism 220, and then the second conveying mechanism 220 will send the luggage basket carrying the items to the next position.

[0064] After the first carrying unit 131 leaves the second workstation, the second carrying unit 132, which was originally in a lower position, rises, and the top edge of the luggage basket it carries becomes flush with the sorting table 141. Passengers can then place their items into the luggage basket carried by the second carrying unit 132. Meanwhile, the third carrying unit 133 moves to the original position of the second carrying unit 132, that is, to a position flush with the first conveying plane of the first conveying mechanism 210, and loads the empty luggage basket delivered by the first conveying mechanism 210. At this time, the two carrying units in the first workstation are the second carrying unit 132 and the third carrying unit 133.

[0065] Therefore, among the four carrying units, two adjacent carrying units alternately occupy the first workstation. That is to say, the carrying units in the first workstation are, in sequence: first carrying unit 131 and second carrying unit 132, second carrying unit 132 and third carrying unit 133, third carrying unit 133 and fourth carrying unit 134, and fourth carrying unit 134 and first carrying unit 131, thus achieving a cycle. This arrangement reduces the time spent switching workstations, further shortens the time for supplying empty luggage baskets, reduces passenger waiting time, and improves security check efficiency.

[0066] like Figure 3 and Figure 4 As shown in the embodiment of this application, the transmission mechanism 120 includes an inner sprocket assembly 123, an outer sprocket assembly 124, an inner chain 122, and an outer chain 121. The inner chain 122 is tensioned and installed on the inner sprocket assembly 123, and the outer chain 121 is tensioned and installed on the outer sprocket assembly 124.

[0067] It should be noted that the transmission structure 120 is mounted on the frame 140. Transmission structures 120 are provided on both opposite sides of the frame 140 along the third direction D3. Specifically, the inner sprocket set 123, outer sprocket set 124, inner chain 122, and outer chain 121 on both sides are symmetrically arranged. The front end of the bearing part in the direction of movement is connected to the inner chain 122, and the rear end of the bearing part in the direction of movement is connected to the outer chain 121. The inner chains 122 and outer chains 121 on both sides can synchronously cooperate in transmission to ensure that the bearing part can move smoothly following the inner chains 122 and outer chains 121 on both sides.

[0068] It should be understood that when the bearing part moves to the set position along the moving direction, the end that reaches the set position first is the front end of the bearing part in the moving direction, and the end that reaches the set position last is the rear end of the bearing part in the moving direction.

[0069] It should be noted that the inner chain 122 and the outer chain 121 can be replaced by a timing belt 233 or a rubber chain.

[0070] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the inner sprocket assembly 123 includes an inner positioning sprocket assembly 123a and an inner winding sprocket assembly 123b. The inner positioning sprocket assembly 123a is used to position the boundary of the inner chain 122, and the inner winding sprocket assembly 123b is disposed between the inner positioning sprocket assemblies 123a to tension the inner chain 122. The outer sprocket assembly 124 includes an outer positioning sprocket assembly 124a and an outer winding sprocket assembly 124b. The outer positioning sprocket assembly 124a is used to position the boundary of the outer chain 121, and the outer winding sprocket assembly 124b is disposed between the outer positioning sprocket assemblies 124a to tension the outer chain 121.

[0071] Understandably, the inner positioning wheel set 123a and the outer positioning wheel set 124a can determine the boundaries of the inner chain 122 and the outer chain 121, thereby determining the highest and lowest positions reached by the support plate. The placement of the inner positioning wheel set 123a and the outer positioning wheel set 124a is related to the size requirements of the lifting device 100. In security inspection scenarios, the height of the lifting device 100 should not be too high, otherwise it would be difficult for passengers to organize their items on the placement surface. However, in order to improve security inspection efficiency, multiple support parts are provided on the inner chain 122 and the outer chain 121, so that the surrounding range of the inner chain 122 and the outer chain 121 is larger than the contours of the inner positioning wheel set 123a and the outer positioning wheel set 124a. Therefore, the inner sprocket assembly 123b and the outer sprocket assembly 124b can be used to tension the inner chain 122 and the outer chain 121. When the diameters of the inner chain 122 and the outer chain 121 are large, the inner chain 122 and the outer chain 121 are stably installed on the inner sprocket assembly 123 and the outer sprocket assembly 124 by winding, so as to ensure that the load-bearing part can operate stably.

[0072] In some implementations, such as Figure 3 and Figure 4 As shown, the inner positioning wheel assembly 123a includes a driving inner sprocket 1231, a first driven inner sprocket 1232, a second driven inner sprocket 1233, and a third driven inner sprocket 1234.

[0073] The driving inner sprocket 1231 and the first driven inner sprocket 1232 are spaced apart along the second direction D2, the second driven inner sprocket 1233 is spaced apart from the first driven inner sprocket 1232 along the first direction D1, and the third driven inner sprocket 1234 is disposed between the driving inner sprocket 1231 and the second driven inner sprocket 1233.

[0074] The driving inner sprocket 1231, the first driven inner sprocket 1232, and the second driven inner sprocket 1233 are located on one side of the inner chain 122, and the third driven inner sprocket 1234 is located on the other side of the inner chain 122, such that the portion of the inner chain 122 between the driving inner sprocket 1231 and the third driven inner sprocket 1234 extends along the second direction D2, and the portion of the inner chain 122 between the third driven inner sprocket 1234 and the second driven inner sprocket 1233 extends along the first direction D1.

[0075] The inner sprocket assembly 123b includes a first inner sprocket 1235 and a second inner sprocket 1236. The first inner sprocket is located between the second driven inner sprocket 1233 and the second driven inner sprocket 1234. The first inner sprocket 1235 is offset from the third driven inner sprocket 1234 in the first direction D1 to increase the complexity of the inner chain extension path. The second inner sprocket 1236 is spaced apart from the third driven inner sprocket 1234 in the first direction D1 so that the inner chain extends along the first direction D1 to the second driven inner sprocket 1233.

[0076] like Figure 3 and Figure 4 As shown, the outer positioning wheel assembly 124a includes a driving outer sprocket 1241, a first driven outer sprocket 1242, a second driven outer sprocket 1243, a third driven outer sprocket 1244, and a fourth driven outer sprocket 1245. The driving outer sprocket 1241 is coaxially arranged with the driving inner sprocket 1231, the first driven outer sprocket 1242 is coaxially arranged with the first driven inner sprocket 1232, the second driven outer sprocket 1243 is coaxially arranged with the second driven inner sprocket 1233, and the third driven outer sprocket 1244 and the second driven outer sprocket 1243 are spaced apart along the second direction D2.

[0077] The outer chain 121 is located on one side of the driving outer chain 1241, the first driven outer chain 1242, the second driven outer chain 1243, and the third driven outer chain 1244, and the fourth driven outer chain 1245 is located on the other side of the outer chain 121, such that the portion of the outer chain 121 between the driving outer chain 1241 and the fourth driven inner chain 1243 extends along the second direction D2, and the portion of the outer chain 121 between the fourth driven inner chain 1243 and the third driven inner chain 1244 extends along the first direction D1.

[0078] The outer sprocket assembly 124b includes a first outer sprocket 1246 and a second outer sprocket 1247. The first outer sprocket is located between the fourth driven outer sprocket 1245 and the third driven outer sprocket 1244. The first outer sprocket 1246 is offset from the fourth driven outer sprocket 1245 in the first direction D1 to increase the complexity of the outer chain extension path. The second outer sprocket 1247 is spaced apart from the fourth driven outer sprocket 1245 in the first direction D1 so that the outer chain extends along the first direction D1 to the third driven inner sprocket 1234.

[0079] It should be noted that the two drive inner sprockets 1231 are connected by a first synchronous shaft, which is mounted on the mounting frame. The drive mechanism 110 is connected to the synchronous shaft 125 to drive the drive inner sprockets 1231 to rotate in the direction of arrow A. For example, the drive mechanism 110 is a motor.

[0080] It should be noted that the transmission mechanism 120 is not limited to the one mentioned above. For example, the transmission mechanism 120 may also include an inner pulley set, an outer pulley set, an inner conveyor belt, and an outer conveyor belt. The inner conveyor belt is tensioned and installed on the inner pulley set, and the outer conveyor belt is tensioned and installed on the outer pulley set. The front end of the bearing part in the direction of movement is connected to the inner conveyor belt, and the rear end of the bearing part in the direction of movement is connected to the outer conveyor belt.

[0081] Furthermore, the supporting part can be a chain plate structure, which is composed of multiple spaced chain plates connected together, and the multiple chain plates are connected by a flexible structure so that the supporting part can follow at least part of the winding of the transmission mechanism 120. The chain plate structure and the connection relationship between the chain plate structure and the inner chain 122 and the outer chain 121 are existing technologies, and will not be described in detail here.

[0082] like Figure 5 As shown, the pushing mechanism 230 includes a driving member, a pushing part 234, and a guide member. The driving member can drive the pushing part 234 to move along the second direction D2 to push the empty luggage basket 300 located in the first conveying mechanism 210 onto the bearing part located in the first work station. The guide member extends along the second direction D2, and the pushing part 234 is slidably connected to the guide member.

[0083] The driving component includes an electric roller 231 and a synchronous belt 233 transmission assembly. The synchronous belt 233 transmission assembly includes multiple synchronous belt pulleys 232 and a synchronous belt 233 tensioned and mounted on the multiple synchronous belt pulleys 232. A pushing unit 234 is connected to the synchronous belt 233. The electric roller 231 drives the synchronous belt 233 to move, thereby driving the pushing unit 234 to move in a set direction. For example, the electric roller 231 rotates clockwise to drive the pushing unit 234 to push the luggage basket 300 onto the support part located at the first workstation; the electric roller 231 rotates counterclockwise so that the pushing unit 234 retracts away from the continuous lifting mechanism, so that the first conveying mechanism 210 can convey the next empty luggage basket 300 to the waiting position.

[0084] It should be noted that the synchronous belt 233 transmission assembly is existing technology. The number and arrangement of the synchronous belt 233 pulleys 232 are not limited to the form shown in the figure. Other arrangements can be selected according to actual needs, as long as the function of the driving part 234 reciprocating in a set direction can be achieved.

[0085] The pushing part 234 includes a pushing plate and a mounting plate. The mounting plate is fixedly connected to the timing belt 233 and is also slidably connected to the guide member to ensure that the pushing part 234 moves along the second direction D2. The pushing plate is fixedly connected to the mounting plate to ensure that the mounting plate and the pushing plate can move together with the timing belt 233.

[0086] In other embodiments, the driving element may also be a telescopic device, which is connected to the pushing part 234, and the telescopic direction of the telescopic device is consistent with the set direction.

[0087] For example, one end of the telescopic device is mounted on the frame 235, and the other end of the telescopic device is connected to the pusher 234. When the luggage basket 300 is in the waiting position, the telescopic device extends, driving the pusher 234 to move in a set direction, so as to push the luggage basket 300 in the waiting position onto the support part in the first position.

[0088] It should be noted that the telescopic device can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0089] In some embodiments, such as Figure 5 As shown, the guide includes guide rods 236. For example, there are two guide rods 236, which are arranged in parallel and spaced apart. The mounting plate is provided with through holes and is sleeved on the guide rods 236. The mounting plate can slide along the extension direction of the guide rods 236. By providing the guide, the stability of the movement of the pushing part 234 can be improved.

[0090] It should be noted that the form of the guide is not limited to the one mentioned above, and other guides can be selected according to the actual situation.

[0091] This application also provides a security inspection system. Figure 6 A schematic diagram of the security inspection system is shown. Figure 1 Multiple sets of conveyor equipment 10 are shown.

[0092] In some implementations, the security inspection system may include a first conveying device 11, a second conveying device 12, and a third conveying device 13.

[0093] The first conveying device 11 shows a structural schematic diagram of the lifting device 100 in the first position. At this time, the height of the lower of the two supporting parts in the first position corresponds to the height of the first conveying mechanism 210, and it can be used to carry the empty luggage basket 300 delivered by the pushing mechanism 230. The higher of the two supporting parts in the first position can be positioned so that the top edge of the luggage basket 300 is flush with the sorting table 141, which is convenient for passengers to place their items.

[0094] The second conveying device 12 shows a structural schematic diagram of the lifting device 100 in the second position. At this time, the two bearing parts that were originally in the first position rise synchronously until the bearing surface of the bearing part in the higher position is flush with the second conveying plane of the second conveying mechanism 220.

[0095] The third conveying device 13 shows a schematic diagram of the lifting device 100 transitioning from the second station to the first station. As the transmission mechanism 120 drives the high-positioned support unit to move, the speed direction of the support unit at its highest position is towards the second conveying mechanism 220. Therefore, the luggage basket 300 can be delivered to the second conveying mechanism 220, and then the second conveying mechanism 220 delivers the luggage basket 300 carrying the items to the next position. Finally, it should be noted that the various embodiments / implementations provided in this application can be combined with each other without contradiction, and will not be described in detail here.
