Description

Technical Field

[0001] This application relates to the field of security monitoring, and particularly to an intelligent luggage security monitoring system. Background Art

[0002] When inspecting luggage, security personnel usually operate with security equipment. During the security inspection process, first, passengers are required to place their luggage in different storage boxes respectively, and then the storage boxes are sent into the security inspection device for inspection. After the security inspection is completed, the passengers can take out the luggage from the storage boxes.

[0003] However, since the storage boxes are continuously sent from the starting end to the ending end of the security inspection device, the number of storage boxes at the starting end of the security inspection device will gradually decrease to zero. At this time, security personnel need to observe the number of storage boxes at the starting end of the security inspection device in real time and frequently move the storage boxes at the ending end of the security inspection device back to the starting end. The operation is cumbersome and troublesome. Summary of the Invention

[0004] In order to improve work efficiency and reduce the burden on security personnel, this application provides an intelligent luggage security monitoring system.

[0005] An intelligent luggage security monitoring system provided by this application adopts the following technical solutions:

[0006] An intelligent luggage security monitoring system includes: a first conveying device for conveying luggage to a first area; a security inspection device arranged on the conveying path of the first conveying device for detecting whether there is any suspicion about the security of the luggage; a carrying device placed at the feeding end of the first conveying device and capable of carrying storage boxes; a weight detection component connected to the carrying device for detecting the weight of the storage boxes on the upper side of the carrying device; a control component, when the weight detection component detects that the weight on the upper side of the carrying device is lower than the weight of one storage box, controlling the first conveying device to convey in the reverse direction; when the weight detection component detects that the weight on the upper side of the carrying device is not less than the weight of one storage box, controlling the first conveying device to convey in the forward direction.

[0007] By adopting the above technical solutions, in the initial state, multiple storage boxes can be placed on the carrying device. Users can take the storage boxes to store luggage and place them on the first conveying device for conveying, and then conduct security inspection through the security inspection device. After the security inspection, the storage boxes are stacked at the ending end of the first conveying device. When the weight detection component detects that the weight of the storage boxes on the upper side of the carrying device is lower than the weight of one storage box, the control component will control the first conveying device to convey in the reverse direction, so that the storage boxes stacked at the ending end of the first conveying device can be placed on the first conveying device and conveyed in the reverse direction to the starting end of the first conveying device. When another storage box is placed on the upper side of the carrying device, the control component controls the first conveying device to convey in the forward direction. The operation is simple, saving the burden on security personnel and improving work efficiency.

[0008] Optionally, the first conveying device includes: a chassis; a plurality of first conveying rollers rotatably arranged on the chassis; a first synchronous transmission member for driving the plurality of first conveying rollers to rotate synchronously; a driving unit for driving the first conveying rollers to rotate, including a movable frame arranged at the feeding end of the chassis and movably connected to the movable frame along the axial direction of the first conveying rollers; two rotary driving members respectively arranged at both ends of the movable frame, the two rotary driving members are coaxially and reversely rotatably arranged, and with the movement of the movable frame, any one of the rotary driving members can be connected to one end of the first conveying roller to drive the first conveying roller to rotate synchronously with the rotary driving member; the control component can drive the movement of the movable frame.

[0009] By adopting the above technical solution, during operation, the two rotary driving members move synchronously and reversely. The rotary driving member that rotates forward is driven by the movable frame to make it connect to one end of the first conveying roller, enabling the first conveying roller to rotate forward. Then, through the first synchronous transmission member, the forward movement of the first conveying device can be realized to transport the items on the upper side of the first conveying device forward; when the movable frame moves and drives the other rotary driving member that rotates reversely to connect to the other end of a first conveying roller, under the action of the first synchronous transmission member, the plurality of first conveying rollers first rotate from forward to stop and then rotate reversely to realize the reverse transportation of the items on the upper side of the first conveying device.

[0010] Optionally, the weight detection component includes: a bearing plate horizontally arranged on the upper side of the bearing device; a first elastic member fixed between the bearing device and the bearing plate.

[0011] By adopting the above technical solution, the storage box can be placed on the bearing plate for receiving. With the first elastic member, buffering during the placement of the storage box can be achieved, reducing the collision of the storage box. When the storage box is removed from the upper side of the bearing plate, the first elastic member can push the bearing plate to rise quickly. When the storage box is placed on the bearing plate, the bearing plate will be affected by the gravity of the storage box and descend.

[0012] Optionally, the control component includes: a lead screw arranged along the movement direction of the movable frame, the lead screw is rotatably connected to the movable frame and threadedly connected to the chassis; a reversing gear coaxially fixed to the lead screw; a first rack vertically fixed to the bearing plate; after the storage box is removed from the upper side of the bearing plate, the first elastic member pushes the bearing plate to rise, driving the first rack to engage with the reversing gear, causing the lead screw to rotate so that the rotary driving member that rotates reversely on the movable frame is connected to one end of the first conveying roller.

[0013] By adopting the above technical solution, after there is no storage box on the upper side of the bearing plate, the first elastic member will push the bearing plate upward, so that the first rack fixed to the bearing plate moves upward synchronously, and then the first rack moves upward to engage with the reversing gear, driving the lead screw to rotate, thus driving the movable frame to move, and further disconnecting the forward-rotating rotary driving member from one end of the first conveying roller and connecting the reverse-rotating rotary driving member to the other end of the first conveying roller. In this way, the reverse operation of the first conveying roller can be realized, and the storage box stacked at the end of the first conveying device can be conveyed back to the bearing plate at the feeding end of the first conveying device in the reverse direction. And when the storage box falls on the bearing plate again, the bearing plate presses the first elastic member and moves downward, so that the bearing plate moves vertically downward, and then drives the first rack to move vertically, so that the first rack can engage with the reversing gear, driving the reversing gear to rotate in the reverse direction, and then driving the lead screw to rotate in the reverse direction. In this way, the movable frame moves in the reverse direction, and the reverse-rotating rotary driving member is disconnected from the first driving shaft again, and the forward-rotating rotary driving member is connected to the other end of the first conveying roller, realizing the forward conveying of the first conveying device.

[0014] Optionally, the first area is provided with: a storage table, vertically movably connected to the chassis, for receiving the storage box; a second elastic member, fixed between the chassis and the storage table, for pushing the storage table upward.

[0015] By adopting the above technical solution, when the storage box loaded with luggage is conveyed to the first area, the storage box will fall onto the storage table, and the passenger can take the luggage out of the storage box. The storage box is stored on the upper side of the storage table. At the same time, the storage table will also move downward under the influence of the gravity of the upper storage box. The subsequent storage boxes conveyed to the first area will be stacked on top of the previous storage boxes continuously, so that the storage of the storage boxes can be completed.

[0016] Optionally, a reverse pushing member is provided between the end of the chassis and the storage table. The reverse pushing member includes: a bevel gear ring, coaxially and rotatably arranged at the end of the first conveying roller of the chassis, and the inner circumferential surface of the bevel gear ring is provided with ratchet teeth; a ratchet pawl, arranged on the circumferential surface of the first conveying roller, inside the bevel gear ring, and disengaging from the bevel gear ring when the first conveying roller rotates forward, and pushing the bevel gear ring to rotate synchronously when the first conveying roller rotates backward; a second rack, vertically fixed to the storage table, and the lower end of the second rack is formed with a toothless section; a linkage shaft, rotatably arranged between the storage table and the chassis, one end of the linkage shaft is fixed with a bevel gear meshing with the bevel gear ring, and the other end is fixed with a reciprocating gear meshing with the second rack. When the second gear rotates, it can push the second rack upward until the reciprocating gear is located at the toothless section of the second rack, and make the storage table not lower than the upper side of the first conveying device.

[0017] By adopting the above technical solution, when the first conveying roller of the first conveying device rotates forward to convey the storage box, the pawl rotates with the first conveying roller and disengages from the engagement with the bevel gear ring, so the ratchet wheel is not controlled by the first conveying roller. When the first conveying roller rotates reversely, the pawl on the circumferential surface of the first conveying roller engages with the internal ratchet wheel of the bevel gear ring, pushing the bevel gear ring to rotate synchronously. The bevel gear ring meshes with the bevel gear, driving the linkage shaft to rotate synchronously. Then, through the reciprocating gear rotating synchronously with the linkage shaft, the reciprocating gear can push the second rack to rise until the reciprocating gear is located at the toothless section at the lower end of the second rack, and the second rack stops rising. At this time, the storage table is pushed by the second rack, so that the height of the storage table is not lower than the upper side of the first conveying device, and further the storage box on the upper side of the storage table is not lower than the upper side of the first conveying device. In this way, the storage box can be conveniently pushed to the first conveying device, and then the storage box can be reversely conveyed to the loading device through the reversely rotating first conveying device.

[0018] Optionally, a pushing device is arranged at the end of the chassis corresponding to the end of the storage table away from the loading device. The pushing device includes: a pushing plate movably arranged on the chassis along the conveying direction of the first conveying device; an upper inclined push rod, one end of which is fixed to the storage table, and the other end of which abuts against the lower side of the pushing plate. When the storage table rises to a position where its upper side is not lower than the first conveying device, the upper inclined push rod can push the pushing plate to move towards the storage table until the storage box on the upper side of the storage table falls onto the first conveying device.

[0019] By adopting the above technical solution, when the storage table moves upward, the upper inclined push rod moves upward synchronously with the storage table, so that the push plate can be pushed to drive the storage table to move, and then the storage box on the storage table falls onto the first conveying device, so that the storage box can be reversely conveyed to the loading device through the first conveying device.

[0020] Optionally, it further includes: a second conveying device arranged under the security inspection device. When the security inspection device detects that the luggage is suspected of being unsafe, the second conveying device outputs the luggage to the second area;

[0021] An identity collector is arranged in the storage box for collecting identity card information;

[0022] An identity recognizer is arranged in the second area for recognizing the identity information collected by the identity collector in the second area;

[0023] An identity display is used for displaying the identity information recognized by the identity recognizer.

[0024] By adopting the above technical solution, with the second conveying mechanism provided and in cooperation with the security inspection device, when a dangerous item is detected in the luggage, the second conveying device can directly convey the dangerous luggage to the second area for easy inspection, avoiding affecting subsequent security inspection passengers. The provided identity collector cooperates with the identity display. After the passenger takes the storage box, the identity collector can directly collect the passenger's ID card information. When the storage box carrying the luggage is sent to the second area, the identity recognizer recognizes the information collected by the identity collector, and the display reads the identity information recognized by the identity recognizer.

[0025] Optionally, the second conveying device includes a lifting frame; a plurality of second conveying rollers rotatably arranged on the lifting frame, the axial direction of the second conveying rollers being perpendicular to the axial direction of the first conveying rollers, and the lifting frame moving vertically to be able to push the second conveying rollers to protrude above the upper side of the first conveying rollers.

[0026] By adopting the above technical solution: when it is necessary to convey the storage box through the second conveying device, the lifting frame rises, driving the second conveying rollers to rise, lifting the storage box located above the first conveying rollers, and then through the rotation of the second conveying rollers, the storage box can be output to the second area through the second conveying device.

[0027] Optionally, it further includes: a height detection module connected to the carrying device for detecting the height of the stacked storage boxes on the carrying device; a lifting module connected to the carrying device for pushing the storage box carrying device to lift or lower. When the height detection module detects that the height of the stacked storage boxes is lower than or higher than a predetermined height, the lifting module pushes the carrying device to rise or fall until the height of the storage box on the upper side of the carrying device conforms to the predetermined height.

[0028] By adopting the above technical solution, when the height of the storage box on the upper side of the carrying device does not conform to the predetermined height, the lifting module can push the carrying device to rise or fall, so that the height of the storage box conforms to the predetermined height for easy access by the user.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. In the initial state, multiple storage boxes can be placed on the carrying device. The user can take a storage box to store luggage, place it on the first conveying device for conveyance, and conduct security inspection through the security inspection device. After the security inspection, the storage boxes are stacked at the end of the first conveying device. When the weight detection component detects that the weight of the storage box on the upper side of the carrying device is lower than the weight of one storage box, the control component will control the first conveying device to convey in the reverse direction, so that the storage boxes stacked at the end of the first conveying device can be placed on the first conveying device and conveyed in the reverse direction to the starting end of the first conveying device. When a storage box is placed on the upper side of the carrying device again, the control component controls the first conveying device to convey forward. The operation is simple, which saves the burden of security inspection personnel and improves work efficiency.

[0031] 2. During operation, the two rotary drive components move synchronously in the opposite direction. The movable frame drives the rotary drive component that rotates forward, making it connected to one end of the first conveying roller, enabling the first conveying roller to rotate forward. Then, through the first synchronous transmission component, the forward movement of the first conveying device can be realized to achieve the forward transportation of the items on the upper side of the first conveying device; when the movable frame moves and drives the other rotary drive component that rotates in the reverse direction to be connected to the other end of the first conveying roller, through the action of the first synchronous transmission component, multiple first conveying rollers first rotate from the forward direction to stop rotating, and then rotate in the reverse direction to achieve the reverse transportation of the items on the upper side of the first conveying device.

Detailed implementation manners

[0045] The following will Figures 1-12 further describe the present application in detail.

[0046] The embodiment of the present application discloses a security monitoring system.

[0047] Referring to Figure 1 , a luggage security monitoring system includes a first conveying device 1 and a security inspection device 2;

[0048] Referring to Figure 1, the first conveying device 1 includes a horizontally arranged chassis 11. The chassis 11 is generally rectangular in shape. A plurality of horizontally arranged first conveying rollers 12 are rotatably connected to the chassis 11. The plurality of first conveying rollers 12 are all arranged along the length of the chassis 11. On one side of the chassis 11, there is a first synchronous transmission component 13 capable of driving the plurality of first conveying rollers 12 to rotate synchronously. The first synchronous transmission component 13 can adopt a chain drive mechanism or a belt drive mechanism.

[0049] Refer to Figure 1 and Figure 2 , at the feeding end of the chassis 11, there is also a driving component capable of driving the first conveying rollers 12 to rotate forward or backward. The driving component includes a movable frame 14. The length direction of the movable frame 14 is arranged along the width direction of the chassis 11. The movable frame 14 is generally U-shaped. The horizontal part of the movable frame 14 is slidably connected to the chassis 11 along its length direction.

[0050] Refer to Figure 2 , rotary driving parts are arranged at both ends of the chassis 11. The rotary driving part includes a spline sleeve 141 rotatably connected to the chassis 11. The axis of the spline sleeve 141 is the same as the axis direction of the first conveying roller 12 at the starting end of the chassis 11. At both ends of the first conveying roller 12 corresponding to the positions of the two spline sleeves 141, spline heads 121 are formed. With the sliding of the movable frame 14, any spline sleeve 141 can be sleeved on the spline head 121 at the corresponding end of the first conveying roller 12, so as to realize the synchronous rotation of the first conveying roller 12 with the spline sleeve 141 inserted therein.

[0051] Refer to Figure 2 , a driving motor 142 is fixed at one end of the chassis 11 away from the other spline sleeve 141 corresponding to one spline sleeve 141. The output shaft of the driving motor 142 is coaxially fixed to the corresponding spline sleeve 141. When the output shaft of the driving motor 142 rotates forward, it can drive the corresponding spline sleeve 141 to rotate forward synchronously. A driving gear 143 is also coaxially fixed on the output shaft of the driving motor 142. A connecting shaft 144 with the same length direction as the chassis 11 is also rotatably connected to the chassis 11. A driven gear 145 meshing with the driving gear 143 is fixed at one end of the connecting shaft 144. A second synchronous transmission component 146, such as a belt drive, a chain drive, etc., is arranged between the other end of the connecting shaft 144 and the other spline sleeve 141. In this way, by the forward rotation of the driving motor 142, the corresponding spline sleeve 141 can be driven to rotate forward, and then through the cooperation of the connecting shaft 144, the driving gear 143, the driven gear 145 and the synchronous transmission component, the other spline sleeve 141 can be driven to rotate backward. In this way, the reverse coaxial rotation of the two spline sleeves 141 is realized. In addition, by adjusting the transmission ratio of the second synchronous transmission component 146, the rotation speed of the reversely rotating spline sleeve 141 can be controlled to be higher than the rotation speed of the forwardly rotating spline sleeve 141.

[0052] Refer to Figure 2, when working, the two spline sleeves 141 move synchronously in opposite directions. Through the movable frame 14, a rotating drive member rotating in the forward direction is driven to move, and it is connected to one end of the first conveying roller 12, enabling the first conveying roller 12 to rotate forward. Then, through the second synchronous transmission member 146, the forward movement of the first conveying device 1 can be achieved to realize the forward transportation of the items on the upper side of the first conveying device 1; when the movable frame 14 moves, driving another rotating drive member rotating in the reverse direction to move and connecting it to the other end of the first conveying roller 12, through the action of the first synchronous transmission member 13, multiple first conveying rollers 12 first rotate from the forward direction to a stop, and then rotate in the reverse direction to realize the reverse transportation of the items on the upper side of the first conveying device 1.

[0053] Referring to Figure 1 and Figure 3 , at the starting end of the first conveying device 1, a loading device 3 is provided. The loading device 3 includes a horizontally arranged loading frame 31. A gravity detection component is arranged on the upper side of the loading frame 31. A control component is also arranged between the gravity detection component and the movable frame 14. The control component is used to control the first conveying device 1 to transport in the reverse direction after the gravity detection component detects that there is no storage box 4 on the upper side of the loading frame 31.

[0054] Referring to Figure 3 , the gravity detection component includes a horizontally arranged bearing plate 32 and a first elastic member 33 vertically fixed to the lower side of the bearing plate 32. The first elastic member 33 can adopt multiple vertically arranged springs. A storage box 4 is placed on the upper side of the bearing plate 32. When the storage box 4 is placed on the bearing plate 32, the first elastic member 33 will be compressed, causing the bearing plate 32 to drop.

[0055] Referring to Figure 2 and Figure 3 , the control component includes a lead screw 147 and a reversing gear 148 arranged on the movable frame 14 and a first rack 34 arranged on the bearing plate 32. The lead screw 147 is arranged along the length direction of the movable frame 14, and the lead screw 147 is rotatably connected to the movable frame 14 and threadedly connected to the base frame 11. The reversing gear 148 is coaxially fixed to the lead screw 147, and the first rack 34 is vertically fixed to the side of the bearing plate 32 close to the base frame 11.

[0056] Referring to Figure 2 Just Figure 3, in the normal state, the spline sleeve 141 rotating in the forward direction is connected to a spline head 121 at the end of the first conveying roller 12 to realize the forward conveying of the first conveying device 1. When the storage box 4 is lost from the upper side of the bearing plate 32, the first elastic member 33 pushes the bearing plate 32 to rise, so that the first rack 34 fixed to the bearing plate 32 moves upward synchronously, and then the first rack 34 moves upward to engage with the reversing gear 148, driving the lead screw 147 to rotate. In this way, the movable frame 14 is driven to move, and then the rotary driving member rotating in the forward direction is disengaged from one end of the first conveying roller 12, and the rotary driving member rotating in the reverse direction is connected to the other end of the first conveying roller 12. In this way, the reverse operation of the first conveying roller 12 is realized, and the storage box 4 stacked at the end of the first conveying device 1 can be reversely conveyed back to the bearing plate 32 at the feeding end of the first conveying device 1.

[0057] Refer to Figure 2 and Figure 4 , and when the storage box 4 falls on the bearing plate 32 again, the bearing plate 32 presses the first elastic member 33 and moves downward, so that the bearing plate 32 moves vertically downward, and then drives the first rack 34 to move vertically, so that the first rack 34 can engage with the reversing gear 148, driving the reversing gear 148 to rotate in the reverse direction, and then driving the lead screw 147 to rotate in the reverse direction. In this way, the movable frame 14 moves in the reverse direction, and the rotary driving member rotating in the reverse direction is disengaged from the first driving shaft again, and the rotary driving member rotating in the forward direction is connected to the other end of the first conveying roller 12, realizing the forward conveying of the first conveying device 1.

[0058] Refer to Figure 1 and Figure 4 , a first area for storing the storage box 4 is provided at the end of the first conveying device 1. An accommodating device 5 is provided in the first area. The accommodating device 5 has a horizontally arranged accommodating table 51. The accommodating table 51 is vertically slidably connected to the bottom frame 11. A second elastic member 52 is provided below the accommodating table 51. The second elastic member 52 can also be a vertically arranged spring fixed between the accommodating table 51 and the bottom frame 11. The second elastic member 52 can push the accommodating table 51 to move upward.

[0059] Refer to Figure 1 and Figure 4 , when the storage box 4 loaded with luggage is conveyed to the first area, the storage box 4 will fall onto the accommodating table 51, and the passenger can take the luggage out of the storage box 4. The storage box 4 is stored above the accommodating table 51. At the same time, the accommodating table 51 will also move downward under the influence of the gravity of the upper storage box 4. The subsequent storage boxes 4 conveyed to the first area will be stacked on top of the previous storage boxes 4 continuously. In this way, the storage of the storage boxes 4 can be completed.

[0060] Refer to Figure 4 and Figure 5A reverse pushing component is provided between the end of the base frame 11 and the storage platform 51. The reverse pushing component includes a bevel gear ring 15 rotatably provided at the end of the base frame 11. The bevel gear ring 15 is coaxially provided with the first conveying roller 12 at the end of the base frame 11. Ratchets 151 are evenly fixed on the inner circumference of the bevel gear ring 15. A pawl 122 is also provided at one end of the first conveying roller 12 corresponding to the bevel gear ring 15. The pawl 122 is located in the bevel gear ring 15. A push spring capable of pushing the pawl 122 to abut against the ratchet 151 of the bevel gear ring 15 is provided at one end of the first conveying roller 12. As the first conveying roller 12 rotates forward, the pawl 122 disengages from the bevel gear ring 15, that is, the first conveying roller 12 rotates alone, and the bevel gear ring 15 does not rotate with the first conveying roller 12. As the first conveying roller 12 rotates in the reverse direction, the pawl 122 pushes the bevel gear ring 15 to rotate synchronously.

[0061] Reference Figure 4 and Figure 5 A second rack 53 is vertically fixed to the lower side of the storage platform 51. The second rack 53 is a helical rack, and a toothless section 531 is formed at the lower end of the second rack 53. A linkage shaft 16 is also provided between the storage platform 51 and the base frame 11. The linkage shaft 16 is rotatably connected to the base frame 11. A bevel gear 161 is coaxially fixed to one end of the linkage shaft 16. The bevel gear 161 is meshed with the bevel gear ring 15. A reciprocating gear 162 is coaxially fixed to the other end of the linkage shaft 16. The reciprocating gear 162 is meshed with the second rack 53. When the bevel gear ring 15 drives the reciprocating gear 162 to rotate through the linkage shaft 16, the reciprocating gear 162 can push the second rack 53 to rise to the point where the reciprocating gear 162 is located at the toothless section 531 of the second rack 53, and at this time, the storage platform 51 is not lower than the upper side of the first conveying roller 12 of the first conveying device 1.

[0062] Reference Figure 4 and Figure 5, when the first conveying roller 12 of the first conveying device 1 rotates forward to convey the storage box 4, the pawl 122 rotates with the first conveying roller 12 and disengages from the engagement with the bevel gear ring 15. Then, the bevel gear ring 15 is not controlled by the first conveying roller 12. When the first conveying roller 12 rotates reversely, the pawl 122 on the circumferential surface of the first conveying roller 12 engages with the internal ratchet of the bevel gear ring 15, pushing the bevel gear ring 15 to rotate synchronously. The bevel gear ring 15 meshes with the bevel gear 161, driving the linkage shaft 16 to rotate synchronously. Then, through the reciprocating gear 162 rotating synchronously with the linkage shaft 16, the reciprocating gear 162 can push the second rack 53 to rise until the reciprocating gear 162 is located at the toothless section 531 at the lower end of the second rack 53, and the second rack 53 stops rising. At this time, the storage table 51 is pushed by the second rack 53, so that the height of the storage table 51 is not lower than the upper side of the first conveying device 1, and further the storage box 4 on the upper side of the storage table 51 is not lower than the upper side of the first conveying device 1. In this way, the storage box 4 can be conveniently pushed onto the first conveying device 1, and then the storage box 4 is reversely conveyed to the loading device 3 by the first conveying device 1 rotating reversely.

[0063] Referring to Figure 4 , at the end of the chassis 11 corresponding to the end of the storage table 51 far from the loading device 3, a pushing device 6 is provided. The pushing device 6 includes a pushing plate 61 and an upper inclined push rod 62. The pushing plate 61 is slidably connected to the chassis 11 along the conveying direction of the first conveying device 1. A tension spring 63 is also fixed between the chassis 11 and the pushing plate 61, and the tension spring 63 can pull the pushing plate 61 to move in a direction away from the storage table 51. One end of the lower end of the upper inclined push rod 62 is fixed to the side of the storage table 51 close to the pushing plate 61, and the upper end of the upper inclined push rod 62 is inclined in a direction away from the storage table 51 and abuts against the lower side of the pushing plate 61. When the storage table 51 rises to a position where the upper side of the storage table 51 is not lower than the upper side of the conveying roller of the first conveying device 1, the upper inclined push rod 62 can push the pushing plate 61 to move in the direction of the storage table 51 until the storage box 4 on the upper side of the storage table 51 falls onto the first conveying device 1.

[0064] Referring to Figure 4 , when the storage table 51 moves upward, the upper inclined push rod 62 moves upward synchronously with the storage table 51, so that the push plate can be pushed to move in the direction of driving the storage table 51, and then the storage box 4 on the storage table 51 falls onto the first conveying device 1, so that the storage box 4 can be reversely conveyed to the loading device 3 through the first conveying device 1.

[0065] Referring to Figure 1 , the security inspection device 2 is arranged in the middle of the chassis 11 in the length direction. A security inspection area for passing luggage is formed between the security inspection device 2 and the upper side of the chassis 11. The scanning unit of the security inspection device 2 can use CT scanning or X-ray scanning to identify the security status of the luggage.

[0066] The overall implementation principle of the embodiments of this application is as follows: In the initial state, the storage boxes 4 are stacked on the bearing plate 32 of the storage device 5. When a passenger's luggage is being security checked, a storage box 4 is taken, the luggage is placed inside the storage box 4, and then it is placed on the first conveying roller 12 of the first conveying device 1. At this time, the spline sleeve 141 at the end of the movable frame 14 close to the motor is connected to the spline head 121 at one end of the first conveying roller 12 at the starting end of the chassis 11. The driving motor 142 rotates, drives the first conveying roller 12 to rotate through the spline sleeve 141, and then drives a plurality of first conveying rollers 12 to rotate through the synchronous transmission member, realizing the forward transmission of the storage box 4 with luggage on the first conveying device 1, so that the luggage passes through the security inspection device 2 for security inspection. The luggage that passes the security inspection is then sent to the first area at the end of the chassis 11, and the storage box 4 falls onto the storage table 51, and the passenger can take the luggage inside the storage box 4.

[0067] The storage box 4 is stored on the storage table 51. With such continuous operation, the storage boxes 4 on the upper side of the bearing plate 32 will gradually be taken away, the weight of the storage boxes 4 on the upper side of the bearing plate 32 will gradually decrease, and the first elastic member 33 will also push the bearing plate 32 to gradually rise. Correspondingly, the stacked storage boxes 4 on the upper side of the storage table 51 will gradually increase, the second elastic member 52 will also be compressed, and the storage table 51 will also gradually descend to facilitate the subsequent storage of the storage boxes 4.

[0068] After there is no longer a storage box 4 on the bearing plate 32, the first elastic member 33 pushes the bearing plate 32 to rise rapidly, so that the first rack 34 on one side of the bearing plate 32 rises rapidly, and then drives the first gear to rotate rapidly through the first rack 34. In this way, the lead screw 147 on the movable frame 14 is driven to rotate, driving the movable frame 14 to slide, and further making the spline sleeve 141 rotating forward on the movable frame 14 disengage from the spline head 121 at one end of the first conveying roller 12, and at the same time, making the spline sleeve 141 rotating in the reverse direction move towards the spline head 121 at the other end of the first conveying roller 12, so that the two are docked. In this way, the first conveying roller 12 on the upper side of the chassis 11 is changed from rotating forward to rotating in the reverse direction.

[0069] When the first conveying roller 12 rotates in the reverse direction, the pawl 122 on the circumferential surface of the first conveying roller 12 at the end of the chassis 11 cooperates with the internal ratchet of the bevel gear ring 15, pushing the bevel gear ring 15 to rotate synchronously. The bevel gear ring 15 meshes with the bevel gear 161, driving the linkage shaft 16 to rotate synchronously. Then, through the reciprocating gear 162 rotating synchronously with the linkage shaft 16, the reciprocating gear 162 can be made to push the second rack 53 to rise until the reciprocating gear 162 is located at the toothless section 531 at the lower end of the second rack 53, and the second rack 53 stops rising. At this time, the storage table 51 is pushed by the second rack 53, so that the height of the storage table 51 is not lower than the upper side of the first conveying roller 12 of the first conveying device 1, that is, the bottom surface of the storage box 4 on the upper side of the storage table 51 is higher than the upper side of the first conveying roller 12 of the first conveying.

[0070] Meanwhile, when the storage table 51 moves upward, the upper inclined push rod 62 moves upward synchronously with the storage table 51, so as to push the push plate to drive the storage table 51 to move in one direction, and further make the storage box 4 on the storage table 51 fall onto the first conveying device 1, so that the storage box 4 can be reversely conveyed to the bearing device 3 through the first conveying device 1.

[0071] After the storage box 4 is reversely conveyed to the bearing plate 32 of the bearing device 3 again, the bearing plate 32 is subjected to the weight of the storage box 4, and the first elastic member 33 is compressed, driving the first rack 34 downward again, and then driving the reversing gear 148 to move reversely, so that the movable frame 14 can be reset again, and the spline sleeve 141 rotating forward is connected to the spline head 121 at one end of the first conveying roller 12, realizing the forward rotation of the first conveying roller 12, so as to facilitate the forward conveying of luggage for inspection.

[0072] Due to the one-way rotation cooperation relationship between the ratchet teeth 151 of the bevel gear ring 15 and the ratchet pawl 122, when the first conveying roller 12 rotates forward, the ratchet pawl 122 is disengaged from the ratchet teeth 151. When the storage box 4 is received on the storage table 51 and the storage table 51 is pressed to move downward, the rotation of the bevel gear ring 15 driven by the rotation of the second rack 53 will not affect the rotation of the first conveying roller 12, ensuring the storage of the storage box 4.

[0073] This kind of structural setting eliminates the need for security inspectors to observe the storage situation of the storage box 4 in real time, and there is no need for security inspectors to manually move the storage box 4, reducing the burden on security inspectors.

[0074] In another embodiment of the present application, in order to facilitate passengers to take the storage box 4, the following solution can be further adopted.

[0075] Refer to Figure 1 and Figure 6 , a lifting unit is arranged on the lower side of the bearing frame 31. The lifting unit adopts a lifting cylinder 35. The lifting cylinder 35 is vertically arranged, and the telescopic rod of the lifting cylinder 35 is fixed upward to the bearing frame 31. A height detector is also fixed on one side of the bottom frame 11 for detecting the height of the storage box 4 on the bearing frame 31.

[0076] Refer to Figure 6 and Figure 7, a controller is connected between the height detector and the lifting cylinder 35. When the height detector detects that the height of the storage boxes 4 stacked on the carrier 31 is higher than the predetermined height, the controller controls the telescopic rod of the lifting cylinder 35 to contract until the height of the storage boxes 4 stacked on the carrier 31 decreases to the predetermined height. When the height detector detects that the height of the storage boxes 4 stacked on the upper side of the carrier 31 is lower than the predetermined height, the controller controls the telescopic rod of the lifting cylinder 35 to extend until the height of the storage boxes 4 stacked on the upper side of the carrier 31 rises to the predetermined height. In addition, when there are no stacked storage boxes 4 on the upper side of the carrier 31, the controller controls the telescopic rod of the lifting cylinder 35 to extend until the carrier 31 rises to the limit height, and this limit height is not higher than the height of the upper side of the conveying rollers of the first conveying device 1.

[0077] Through this set of solutions, when passengers pick up the storage boxes 4, the storage boxes 4 at the position of the carrying device 3 can always be at the same height, which is convenient for passengers to pick up.

[0078] In addition, during the safety inspection process of luggage, when there are doubts about the safety of the luggage, it is often directly required that the luggage owner open the luggage for manual screening at the end of the security inspection equipment. However, when the passenger flow is large, on the one hand, there is a possibility that the luggage holder cannot be found in time. On the other hand, the inspectors and the inspected are blocked at the end of the security inspection equipment, which will also affect the normal inspection of subsequent luggage, resulting in low efficiency of luggage handling and poor passenger experience. Therefore, in another embodiment of the application, the second conveying device 7 can be further adopted to convey the luggage with potential danger to the second area, so as to distinguish it from the first area and realize the rapid security inspection of normal luggage. The following is a further detailed description.

[0079] Refer to Figure 8 , the second conveying device 7 includes a reversing conveying component 71 and an output component 72.

[0080] Refer to Figure 8 and Figure 9 , the reversing conveying component 71 is arranged under the security inspection device 2. The reversing conveying part includes a lifting frame 711 that is horizontally arranged and vertically slidably connected to the chassis 11. A regulating cylinder 712 is vertically fixed to the lower side of the chassis 11 corresponding to the lifting frame 711 (refer to Figure 10), the telescopic rod of the adjusting cylinder 712 is fixed to the lifting frame 711. A plurality of second conveying rollers 713 are rotatably connected to the lifting frame 711. The axial direction of the plurality of second conveying rollers 713 is perpendicular to the axial direction of the first conveying roller 12. The second conveying rollers 713 are arranged in the gaps between adjacent first conveying rollers 12, and the second conveying rollers 713 can all be electric rollers. On one side of the security inspection device 2 corresponding to the conveying direction of the second conveying rollers 713, there is an outlet 21 for receiving the boxes 4 and outputting the luggage. When the security inspection device 2 detects that the luggage is suspected of being unsafe, the lifting frame 711 rises, so that the upper side of the second conveying rollers 713 protrudes above the upper side of the first conveying rollers 12, thereby lifting the boxes 4 on the upper side of the first conveying rollers 12, and then conveying the boxes 4 suspected of being dangerous out of one side of the security inspection device 2 through the second conveying rollers 713.

[0081] Refer to Figure 8 and Figure 9 , the output component 72 includes a bracket 721. One end of the bracket 721 is docked to the outlet 21 of the installation device. A third conveying roller 722 is rotatably arranged on the bracket 721. The axial direction of the third conveying roller 722 is perpendicular to the length direction of the bracket 721, and the third conveying roller 722 can also be a driving roller. The end of the bracket 721 is set as the second area.

[0082] Refer to Figure 8 and Figure 9 , when the luggage is output through the outlet 21 of the security inspection device 2, it can be conveyed to the second area through the third conveying roller 722, so as to facilitate the passengers to open the luggage for inspection.

[0083] In order to quickly notify the passengers whose luggage is suspected to go to the second area for inspection, in another embodiment of the present application, an identity collector 41, an identity identifier 8 and an identity display 81 can also be set.

[0084] Refer to Figure 11 and Figure 12 , the identity collector 41 is fixed to each box 4. The identity collector 41 is used to collect the identity card information of the passengers, such as name information and gender information, etc. The identity identifier 8 is arranged in the second area to identify the latest name information and gender information collected by the identity collector 41, etc. The identity display 81 is also arranged in the second area and connected to the identity identifier 8. The identity display 81 is used to read and display the name information and gender information identified by the identity identifier 8, etc., so as to inform the owner of the luggage to go to the second area to accept the opening inspection of the luggage.

[0085] With the above - adopted solution, when a passenger takes the storage box 4, the identity is collected by the identity collector 41 when taking the ID card. Then, the luggage is placed in the storage box 4 and conveyed through the first conveying device 1, and then enters the security inspection device 2 for security inspection. After detecting luggage with potential danger, the second conveying device 7 sends the storage box 4 containing the dangerous luggage to the second area. The identity recognizer 8 in the second area first recognizes the identity information collected by the identity collector 41. Then, the identity display 81 reads and displays the identity information collected by the identity collector 41. The owner of the luggage can quickly go to the second area to accept the opening inspection of the luggage through the information on the identity display 81.

[0086] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
