[0056] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0057] Example 1 of the intelligent security inspection system of the present invention:

[0058] like Figure 1 As shown, the intelligent security inspection system includes a cargo conveyor channel 1, a continuous basket supply device 2, and intelligent security inspection equipment (not shown). The continuous basket supply device 2 is used to continuously provide empty luggage baskets 4 for passengers to place their luggage into. After the luggage is placed in the empty luggage baskets 4, the luggage baskets 4 are pushed onto the cargo conveyor channel 1. The cargo conveyor channel 1 is used to transport the luggage baskets 4 to the intelligent security inspection equipment for inspection. Multiple continuous basket supply devices 2 can be arranged side by side along the conveying path of the luggage baskets 4, allowing multiple passengers to place their luggage into the luggage baskets 4 simultaneously, further improving security inspection efficiency.

[0059] The continuous basket feeding device 2 includes a frame 23, and a basket feeding conveyor 3 is provided at the bottom of the frame 23. Figure 2 As shown, a basket inlet space is formed above the basket inlet conveyor 3 for empty totes 4 to enter. A basket storage cavity 234 is located above the basket inlet space for storing empty totes 4. Multiple totes 4 can be stacked in sequence within the storage cavity 234. Fixed one-way blocks 235 are fixed to the walls of the storage cavity 234 to block and support the totes 4 in one direction. When the totes 4 in the basket inlet space move upward, they can pass over the fixed one-way blocks 235 and be supported on them. A basket lifting mechanism 21 is mounted on the frame 23 for lifting the totes 4 in the basket inlet space into the storage cavity 234. A basket pushing mechanism 22 is also mounted on the frame 23 for pushing the topmost tote 4 in the storage cavity 234 outward onto the cargo conveying channel 1. The continuous basket supply device 2 also includes a control assembly that identifies, receives, and processes basket lifting and pushing signals, controlling the coordinated operation of the basket lifting and pushing mechanisms 21 and 22 to achieve continuous basket supply.

[0060] As shown in Figures 2-4 , the lifting basket mechanism 21 includes movable one-way blocking members 211 for unidirectional blocking and supporting the luggage baskets 4 and a driving mechanism for driving the movable one-way blocking members 211 to move up and down, the movable one-way blocking members 211 have an initial position below the fixed one-way blocking members 235 and a pushing position not lower than the fixed one-way blocking members 235 in their moving stroke, when the movable one-way blocking members 211 are below the fixed one-way blocking members 235 and move up from the initial position to the pushing position, the movable one-way blocking members 211 push the upper luggage baskets 4 and lift the upper luggage baskets 4 up by one basket position. The lifting basket mechanism 21 has two groups and is arranged on opposite sides of the basket storage cavity 234, the fixed one-way blocking members 235 have two groups and are arranged on one side of the two groups of lifting basket mechanisms 21.

[0061] As shown in Figure 5 , the luggage basket 4 is a rectangular basket with an open upper end, the two wide edges of the top of the rectangular basket are higher than the two long edges, the two wide edges constitute the luggage basket support edges 41, the upper part of the rectangular frame is provided with an outward turning edge 43, the left and right side plates of the rectangular basket are respectively provided with slide ways 42 extending in the width direction of the rectangular basket at positions close to the bottom, when two or more luggage baskets 4 are stacked in sequence, as shown in Figure 6 , the two slide ways 42 of the upper luggage basket 4 can be correspondingly supported on the two luggage basket support edges 41 of the adjacent lower luggage basket 4, and when the upper luggage basket 4 is pushed, the two slide ways 42 can slide along the two luggage basket support edges 41 of the lower luggage basket 4.

[0062] As shown in Figure 7 , the fixed one-way blocking member 235 is a lock tongue structure, when the luggage basket 4 moves up, the lock tongue is compressed back to enable the luggage basket 4 to move up and pass the lock tongue, after the outward turning edge 43 of the luggage basket 4 passes the lock tongue, the outward turning edge 43 loses the compression of the lock tongue, the lock tongue automatically rebounds to the position below the outward turning edge 43, the planar part of the lock tongue constitutes a supporting part for supporting the luggage basket 4. The fixed one-way blocking member 235 is provided with two groups, each group includes two fixed one-way blocking members 235, the two fixed one-way blocking members 235 of the same group are arranged in a horizontal direction, the two groups of fixed one-way blocking members 235 are symmetrically arranged on opposite sides of the basket storage cavity 234, thereby providing stable and reliable support for the luggage baskets.

[0063] The movable one-way blocking member 211 and the fixed one-way blocking member 235 have the same structure, both are lock tongue structures. As shown in Figure 4As shown, when the movable one-way blocking piece 211 is moved downward, it is pressed to retract by the outer turning edge 43 of the luggage basket 4, and after the movable one-way blocking piece 211 passes the outer turning edge 43, it automatically rebounds to support below the outer turning edge 43. Thereafter, the movable one-way blocking piece 211 will be driven by the driving mechanism to move upward with the luggage basket 4, and the luggage basket 4 will push the upper luggage basket 4 to lift the upper luggage basket 4 by one basket position.

[0064] The lifting basket mechanism 21 is provided with two groups and symmetrically arranged on the opposite sides of the storage basket cavity 234 along the basket conveying direction of the basket conveying machine 3, and each group of the lifting basket mechanism 21 includes two movable one-way blocking pieces 211. The two movable one-way blocking pieces 211 of the same group of the lifting basket mechanism 21 are arranged in a horizontal direction. The four movable one-way blocking pieces 211 are in four-point contact support with the luggage basket 4, so as to drive the luggage basket 4 to move upward stably. During the basket feeding operation, the lifting basket mechanism upstream in the basket conveying direction is in a lifted state to avoid the luggage basket 4, and the lifting basket mechanism downstream in the basket conveying direction is in a lowered state to block and position the incoming luggage basket 4. When the luggage basket 4 is blocked by the lifting basket mechanism downstream in the basket conveying direction, it indicates that the basket feeding is in place. At this time, the control assembly controls the lifting basket mechanism upstream to be lowered and cooperates with the lifting basket mechanism downstream to lift the luggage basket 4. During the lifting process, the two groups of the lifting basket mechanism 21 move synchronously to drive the luggage basket to move upward and downward, which fully guarantees the stability of the luggage basket moving upward and downward.

[0065] The driving mechanism includes a driving motor 212, as shown in FIG. 6, and the driving motor 212 is connected with the movable one-way blocking piece 211 through a transmission mechanism. Figures 2-3As shown, the output end of the drive motor 212 is connected to the movable one-way blocking member 211 through a screw-nut mechanism to drive the movable one-way blocking member 211 to move up and down. The frame 23 includes a bottom frame 231, a top frame 233, and a plurality of pillars 232 connected between the bottom frame 231 and the top frame 233. The top of the bottom frame 231 is provided with a fixed crossbeam, and the drive motor 212 is fixedly mounted on the fixed crossbeam. The screw-nut mechanism extends up and down. The output end of the drive motor 212 is connected to the screw 215. The upper end of the screw 215 is rotatably assembled on the top frame 233. The screw 215 is externally threaded with a nut seat 214. The nut seat 214 is connected to the inverted U-shaped lifting frame 213. Two pillars 232 simultaneously pass through the inverted U-shaped lifting frame 213 to circumferentially limit the inverted U-shaped lifting frame 213 and guide it up and down, so that the inverted U-shaped lifting frame 213 and the nut seat 214 can only move linearly in the up and down directions. The fixed crossbeam has two through-holes, into which the two side arms of the inverted U-shaped lifting frame 213 are respectively movably mounted in the vertical direction. Two movable one-way blocks 211 of the same basket-lifting mechanism are fixedly mounted at the ends of the two side arms of the inverted U-shaped lifting frame 213. The fixed one-way block 235 is fixedly mounted on the fixed crossbeam and positioned above the movable one-way block 211. When the drive motor 212 rotates, it drives the lead screw 215 to rotate synchronously, causing the nut seat 214 to move up and down along the lead screw 215, thereby driving the inverted U-shaped lifting frame 213 and the movable one-way block 211 fixed to the inverted U-shaped lifting frame 213 to move up and down.

[0066] like Figure 8 As shown, the basket pushing mechanism 22 includes two synchronous chains 221 and push rods 222 connected to the two synchronous chains 221. The two synchronous chains 221 are synchronized via a synchronous connecting rod 225, which in turn drives the push rods 222 in a circular motion, achieving continuous basket pushing. Two push rods 222 are provided, spaced apart on the synchronous chains 221, and take turns pushing the basket. Sprockets 223 are mounted at the corners of the frame 23. The sprockets 223 cooperate with the chains to cause the chains to reverse direction at the corners of the frame 23. One of the sprockets is a driving sprocket, while the others are driven sprockets. A sprocket drive motor 224 is fixedly mounted on the frame 23. A reduction mechanism is connected between the sprocket drive motor 224 and the driving sprocket. Driven by the sprocket drive motor 224, the two synchronous chains 221 move in a circular motion, achieving continuous basket pushing.

[0067] The basket pushing direction of the basket pushing mechanism 22 is perpendicular to the basket feeding direction of the basket feeding conveyor 3, so as to avoid interference between the synchronous chain 221 and the basket feeding conveyor 3, and the structural arrangement is more convenient. In addition, multiple continuous basket feeding devices can be arranged in parallel along the basket feeding direction and the basket pushing mechanism can be placed next to the conveyor line, which is convenient for the use of multiple continuous basket feeding devices together, so that multiple passengers can put in their luggage at the same time, further improving the security inspection efficiency.

[0068] like Figure 9 As shown in the figure, the specific action process of the continuous basket supply device is as follows:

[0069] The two movable one-way blocking members 211 of the basket lifting mechanism 21 located upstream in the basket feeding direction are positioned in an upward pushing position to avoid the luggage basket 4, and the two movable one-way blocking members 211 of the basket lifting mechanism 21 located downstream in the basket feeding direction are moved downward to an initial position to block and limit the incoming luggage basket 4; the luggage basket 4 on the conveyor line flows into the basket inlet space and is blocked by the two movable one-way blocking members 211 of the basket lifting mechanism 21 located downstream in the basket feeding direction; a signal is issued when the top luggage basket in the basket storage cavity 234 has been fully loaded. The basket pushing mechanism 22 pushes the top luggage basket 4 into the cargo conveying channel 1, and then detects that the luggage basket 4 has been pushed into place. The two movable one-way blocking members 211 of the basket lifting mechanism 21 located upstream in the basket feeding direction descend synchronously. Then, the four movable one-way blocking members 211 of the two groups of basket lifting mechanisms 21 move upward simultaneously to lift the luggage basket 4 on the basket feeding conveyor 3. During the rising process, they push the upper luggage basket 4 and lift the upper luggage basket 4 upward by one basket position. When the top luggage basket 4 is lifted into place, the passenger can now place the next piece of luggage.

[0070] The intelligent security inspection system of the present invention can realize automatic and continuous supply of luggage baskets, reducing the need for passengers to bend down to pick up and push luggage baskets by themselves, reducing the labor intensity of passengers and improving the user experience. After one piece of luggage is put in, the next luggage basket is quickly lifted into place, saving the operating time of passengers who manually pick up and push the baskets by themselves, and shortening the waiting time for the supply of luggage baskets, thereby greatly improving the security inspection efficiency.

[0071] Of course, the intelligent security inspection system of the present invention is not limited to the above embodiments.

[0072] For example, in other embodiments, the basket lifting mechanism includes a support block, a first drive mechanism for driving the support block horizontally, and a second drive mechanism for driving the support block vertically. After the luggage basket enters the basket entry space, the first drive mechanism is controlled to drive the support block horizontally so that the support block rests on the lower portion of the luggage basket's outer edge. The second drive mechanism is then controlled to drive the support block upward, thereby lifting the support block. Once fully lifted, the second drive mechanism is controlled to drive the support block downward, and the first drive mechanism is controlled to drive the support block horizontally back to its original position, ready for the next lift. The drive mechanism can be a drive motor or a telescopic cylinder.

[0073] For example, in other embodiments, the basket lifting mechanism includes a supporting plate and a driving mechanism for driving the supporting plate to move up and down, the driving mechanism can be a driving motor or a telescopic cylinder, the supporting plate is used to support the luggage basket, the luggage basket flows onto the supporting plate after entering the basket entering space, the driving mechanism drives the supporting plate to move up, thereby pushing the upper luggage basket and lifting the upper luggage basket upward by one basket position.

[0074] For example, in other embodiments, the basket lifting mechanism can also be provided with only one group or three groups, four groups, etc., and the specific arrangement position can be flexibly adjusted according to the overall structure of the device.

[0075] For example, in other embodiments, the fixed one-way blocking piece has two groups, each group includes three or more fixed one-way blocking pieces, and all fixed one-way blocking pieces in the same group are arranged in sequence and spaced apart in the horizontal direction. Of course, each group can also have only one fixed one-way blocking piece, in which case the size of the fixed one-way blocking piece can be appropriately increased to have a larger blocking surface with the luggage basket.

[0076] For example, in other embodiments, each group of basket lifting mechanisms includes three or more movable one-way blocking pieces, and all movable one-way blocking pieces of the same group of basket lifting mechanisms are arranged in sequence and spaced apart in the horizontal direction. Of course, each group of basket lifting mechanisms can also have only one movable one-way blocking piece, in which case the size of the movable one-way blocking piece can be appropriately increased to have a larger blocking surface with the luggage basket.

[0077] For example, in other embodiments, the driving mechanism for driving the movable one-way blocking piece to move up and down can be a linear motor, the output end of the linear motor is directly or indirectly connected with the movable one-way blocking piece to drive the movable one-way blocking piece to move up and down. The driving mechanism can also use a telescopic cylinder, etc.

[0078] For example, in other embodiments, the output end of the driving motor is connected with the movable one-way blocking piece through a screw nut mechanism to drive the movable one-way blocking piece to move up and down, the screw nut mechanism extends up and down and its nut rotates and is arranged on the rack, the output end of the driving motor is connected with the nut, the screw is movably installed on the rack in the up-down direction, the screw is connected with a mounting plate, and the movable one-way blocking piece is fixedly installed on the mounting plate. The driving motor drives the nut to rotate, thereby driving the screw, the mounting plate and the movable one-way blocking piece to move up and down.

[0079] For example, in other embodiments, a synchronous belt is used instead of a synchronous chain.

[0080] For example, in other embodiments, the basket pushing mechanism uses a telescopic cylinder, the telescopic cylinder is fixedly installed on the top of the rack, and the luggage basket is pushed forward by the telescopic cylinder.

[0081] For example, in other embodiments, the pushing direction of the basket pushing mechanism can be parallel to the feeding direction of the basket feeding conveyor.

[0082] For example, in other embodiments, the control assembly controls the two groups of basket lifting mechanisms to move synchronously, at which time a sensor can be additionally arranged at the bottom of the rack to indicate that the luggage basket has arrived at the in-basket position. After the luggage basket arrives at the in-basket position, the control assembly controls the two groups of basket lifting mechanisms to move synchronously downward and, after the active one-way blocking member passes over the outer turning edge of the upper part of the luggage basket downward, the control assembly controls the two groups of basket lifting mechanisms to move synchronously upward to lift the luggage basket.

[0083] The application also provides an embodiment of a continuous basket supply device, which has the same specific structure as the continuous basket supply device in the intelligent security inspection system described above, and thus will not be described here.

[0084] The above description is only the preferred embodiments of the present application, and is not intended to limit the present application. The patent protection scope of the present application is subject to the claims, and any equivalent structural changes made according to the content of the specification and drawings of the present application shall also be included in the protection scope of the present application.
