Description

Technical Field

[0001] This invention relates to the field of airport automated security inspection equipment, specifically to a baggage basket stacking and collection device. Background Technology

[0002] With the development of new-generation information technologies such as the Internet of Things, artificial intelligence, and big data, passenger security checkpoints, which previously required a large number of security personnel, are gradually undergoing machine-based upgrades. Before the upgrades, most security systems used roller or belt conveyors connected to X-ray machines for inspection. During this process, security personnel needed to continuously collect used luggage baskets from each passenger and move them to the front for subsequent passengers to use. Passengers manually picking up and putting away baskets was inefficient and difficult to manage.

[0003] The advent of brand-new automated security screening equipment has completely changed this situation, achieving fully automated processing and ensuring real-time interconnection of passenger information and baggage. After passengers place their luggage into empty baskets on the automatic basket feeding station, the upper detection line automatically detects, sorts, and re-inspects them. After passengers take their luggage, the collection device stacks and collects the empty baskets, then transports them to the lower line, unstacks them, and returns them to the upper level for subsequent passengers to use.

[0004] Currently, there are three main types of luggage basket collection devices. The first type, as described in CN112811196A / CN111257963A, uses a variable-pitch screw lifting mechanism. Through the engagement of the variable-pitch screw, empty baskets are simultaneously disassembled during transport to the lower level. This stacking and disassembly collection method is noisy, has a limited number of baskets, and its conveying efficiency is low due to the screw speed limitation. It is also prone to basket jamming and requires cumbersome maintenance. The second type, such as CN110155731A / CN108572398A, uses a combination of a basket clamping mechanism and a lifting bracket mechanism. The basket clamping mechanism is responsible for limiting the empty baskets, and the lifting bracket is responsible for removing the bottom baskets. Both use independent power units, which leads to complicated debugging processes and high costs due to the use of multiple electric cylinders and motors, resulting in poor stability. The third type, such as invention patent CN115303813A, uses a push-pull rod and lifting arm structure. The lifting arm is used to lift or release the luggage baskets, and two sets of push-pull rods are used to separate the bottom luggage baskets. The linkage of these three mechanisms increases the debugging cycle and reduces the stability and conveying efficiency of the equipment. Summary of the Invention

[0005] To address the technical problems existing in the aforementioned security inspection equipment, this application provides a luggage basket stacking and dismantling collection device, which integrates stacking collection and dismantling return functions. A cam and crank-connecting rod structure is used as the actuator to complete the stacking and dismantling of baskets. This solution increases the number of baskets that can be collected, simplifies the structure, facilitates installation and maintenance, and significantly improves reliability, economy, and conveying efficiency.

[0006] This invention first provides a luggage basket stacking and collection device, including a frame and a basket separating module, a return module and a cover component disposed on the frame;

[0007] The frame includes a rectangular profile frame and a motor mounting plate disposed at the bottom of the profile frame;

[0008] The basket sorting module includes a power unit, a rotating component, and a cam mechanism; the power unit is fixed on a motor mounting plate and is used to provide the power required by the basket sorting module; the rotating component includes a rotating shaft; the power unit delivers power to the basket sorting component through the rotating shaft; two sets of the cam mechanisms are mirror images arranged on both sides of the frame, and the cam mechanisms are used to stack and unstack the luggage baskets;

[0009] The return module is located at the lower end of the frame and is used to receive and output the luggage basket at the lower end of the frame.

[0010] The enclosure component is disposed outside the frame and covers the frame; the enclosure component includes a guide plate for guiding the luggage baskets when collecting them.

[0011] As a preferred embodiment of the present invention, the power unit includes a drive motor, a reducer, a motor mount, a drive pulley, a synchronous belt, and a driven pulley; the drive motor and the reducer are fixed to the motor mounting plate via the motor mount; the drive pulley is fixedly mounted on the shaft of the reducer, and the driven pulley is fixedly mounted on the rotating shaft; the drive pulley transmits power to the driven pulley via the synchronous belt, thereby causing the driven pulley to drive the rotating shaft to rotate.

[0012] As a preferred embodiment of the present invention, the rotating assembly further includes a crank and a synchronous connecting rod; the cam mechanism includes a basket bottom plate, a leveling block, a basket top plate, a linear guide rail, a lifting crank, a cam, a lifting arm, a telescopic arm, a telescopic guide post, and a return spring; the basket top plate is fixed to the basket bottom plate by the leveling block, and the basket top plate and the basket bottom plate together form the skeleton of the cam mechanism; the cam's rotating shaft is fixed to the basket bottom plate; one end of the synchronous connecting rod is connected to the rotating shaft by the crank, and the other end is connected to the cam's rotating shaft by the crank; the linear guide rail is vertically arranged at the lower end of the side of the basket top plate; the lifting arm is arranged on the linear guide rail and is connected to the cam by the lifting crank; the telescopic guide post is fixed to the upper end of the side of the basket bottom plate, and a return spring is sleeved on the telescopic guide post; the telescopic arm is slidably arranged on the telescopic guide post.

[0013] As a preferred embodiment of the present invention, the cover component is provided with a full stack sensor, a bottom layer touch sensor and a return sensor; the full stack sensor is used to detect whether the luggage baskets in the luggage basket stacking and dismantling collection device have reached the maximum storage quantity; the bottom layer touch sensor is used to detect whether there are still baskets in the luggage basket stacking and dismantling collection device; and the return sensor is used to detect whether the luggage baskets have been completely sent out during the return process.

[0014] The present invention also provides a method for stacking and collecting luggage baskets using the above-mentioned luggage basket stacking and collecting device, comprising the following steps:

[0015] 1) Start the power unit in the luggage basket stacking and collection device. The power unit rotates, which in turn drives the rotating shaft to rotate.

[0016] 2) The rotating shaft drives the synchronous connecting rod to move through a crank set at one end of the synchronous connecting rod, and the synchronous connecting rod converts the displacement into the rotation of the cam through a crank set at the other end;

[0017] 3) As the roller abuts against the side of the cam with the track block under the action of the return spring, the roller is squeezed when the track block abuts against the roller. The telescopic guide block fixedly connected to the roller transmits the squeezing force to the return spring, the return spring is compressed, and the telescopic arm retracts to release the bottom luggage basket.

[0018] At the same time, the rotation of the cam causes the lifting crank to move, and the lifting crank drives the telescopic arm to rise along the linear guide rail to support the bottom luggage basket.

[0019] 4) The cam continues to rotate, the track block passes the roller, the return spring returns to its original position, the telescopic arm extends and supports the stack of luggage baskets; while the telescopic arm descends along the linear guide rail, finally placing the bottom luggage basket onto the return module to send the bottom luggage basket out.

[0020] 5) The luggage baskets returned by the external conveyor belt are guided by the guide plate and fall into the luggage basket stacking and collection device, and the luggage baskets are stacked in sequence.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1) Because the present invention adopts a cam crank structure, it overcomes the problem of frame jamming in the variable pitch screw mechanism in the prior art, thereby achieving the effect of improved reliability and durability.

[0023] 2) Because the present invention adopts a single motor linkage drive method, it overcomes the problems of high cost, difficult maintenance and large space occupation caused by multiple motor drives in the existing technology, thus achieving the effects of high economy, compact structure and easy maintenance.

[0024] 3) Because the present invention uses a lifting arm and a telescopic arm to lift and raise the basket, it overcomes the problem of noise generated by squeezing and friction during the conveying of baskets in the prior art, thus achieving a quiet environment that is more in line with the requirements of airport use.

[0025] 4) Because the present invention uses a cam crank structure to perform stacking and destacking, it overcomes the problems of the prior art that it cannot stack or has a small number of baskets and low basket delivery efficiency, thus achieving high capacity and high efficiency.

[0026] 5) Because this invention uses a horizontal positioning guide plate and a vertical positioning telescopic arm, it overcomes the vibration problem caused by friction-limited conveying in the prior art. This results in smooth operation and a low failure rate. Attached Figure Description

[0041] The present invention will be further described and illustrated below with reference to specific embodiments. The embodiments described are merely examples of the content of this disclosure and do not limit the scope of the invention. The technical features of each embodiment in the present invention can be combined accordingly, provided that there is no mutual conflict.

[0042] like Figure 1 As shown, a luggage basket stacking and collection device comprises a basket sorting module 2, a return module 3, and a cover component 4 mounted on a frame 1. This constitutes the luggage basket stacking and collection device.

[0043] like Figure 2 As shown, guided by the cover component 4, the luggage baskets are stacked in the collection device. The stacked luggage baskets 6 are lifted by the telescopic arm 219, and the lifting arm 218 transports the separated bottom luggage baskets 5 to the return module 3.

[0044] like Figure 3 As shown, the frame 1 is constructed from a profile frame 101 and its mounting plate. The motor mounting plate 103 is located on the lower section beam of the frame, and a return fixing block 2 is arranged on it for mounting the return module 3 and the drive mechanism of the basket separating module 2. The bottom of the frame 1 is equipped with feet 104 for supporting the whole machine and adjusting its level. The cover fixing plate 105 is installed at the front end of the frame 1, and it is combined with the profile frame 101 to position the cover component 4.

[0045] exist Figure 4 In this module, sorting module 2 mainly consists of a power source and cam mechanisms on both sides. The drive motor 201 is connected to the drive wheel 204 via a reducer 202. The drive wheel 204 drives the synchronous belt 205, driven wheel 206, and rotating shaft 207 to move. The rotating shaft 207 transmits power to the cam mechanisms on both sides. The left and right cam mechanisms are mirror images of each other. The rotating shaft 207 is fixed by bearing seats 208 on both sides. When the rotating shaft 207 drives the crank 209 to rotate, and each cam 217 is connected to the upper crank 209 and synchronous connecting rod 210, the function of one motor driving four cams to rotate synchronously can be achieved. Figure 5 As shown, cam 217 is mounted on cam bearing seat 222, and two cam bearing seats 222 are mounted on each basket bottom plate 211. When cam 217 rotates, it will drive telescopic arm 219 and lifting arm 218 to act simultaneously. Basket top plate 213 is mounted on basket bottom plate 211 via equalizing block 212. Telescopic guide post 220 and reset spring frame 221 are installed between basket top plate 213 and basket bottom plate 211, which can realize the reset action of telescopic arm. Figure 7 , Figure 8 As shown, the cam 217 is equipped with a cam disk 2171, a track block 2172, and a lifting shaft 2173. The lifting arm 218 reciprocates up and down as the cam 217 rotates, as... Figure 13 As shown, the distance from the center of cam 217 to the center of the lifting shaft is a, and the length of crank 216 is b. According to the law of cosines, the relationship between the position H of lifting arm 218 and the rotation angle B of cam 217 can be determined:

[0046] c 2 =b 2 -a 2 +2accosB

[0047] H = a + bc

[0048] like Figure 9 As shown, the telescopic arm 219 is equipped with a telescopic guide block 2191 and a roller 2192. Figure 6As shown, roller 2192 travels on cam 217, and the guide hole on telescopic guide block 2191 cooperates with telescopic guide post 220, compressing return spring 221. Lifting shaft 2173 on the cam is connected to lifting crank 216, which drives slider 215 to move up and down on linear guide rail 214. Lifting arm 218 is mounted on slider 215, guided by the guide rail slider and driven by cam 217, completing the up-and-down reciprocating motion. The roller 2192 on the telescopic arm 219 is abutted by the track block 2172 mounted on the cam 217. Due to the compression force of the return spring 221, the telescopic arm 219 always reciprocates in the axial direction of its rotation axis as the cam 217 rotates. When the track surface of the track block 2172 rises, the roller 2192 moves on the rising track surface 2172-1, and the telescopic arm 219 also moves outward along the axial direction of the cam 217. At this time, the return spring 221 is further compressed. The track flat surface 2172-2 is perpendicular to the axial direction of the cam 217. After the roller 2192 enters the track flat surface 2172-2, the roller 2192 continues to roll, but no relative movement occurs in the axial direction of the rotation axis, and the telescopic arm 219 also remains in a fixed position. When the track surface descends, and the roller 2192 moves on the descending track surface 2172-3, the return spring 221 is released, and the telescopic arm 219 moves inward, completing the extension action. At this point, the rotation of cam 217 simultaneously drives the lifting arm 218 to move linearly in a direction perpendicular to the telescopic arm 219. The positional relationship between the lifting shaft 2173 and the track block 2172 ensures that when the lifting arm rises and almost contacts the bottom basket, the roller 2192 is located on the rising surface of the track and can retract synchronously. When the lifting arm reaches its top and contacts the bottom basket, the roller 2192 will also begin to enter the flat surface of the track and run on the flat surface, remaining in the retracted state. When the lifting arm 218 lowers the bottom basket a certain distance, and the upper edge of the bottom basket is just away from the height range of the telescopic arm 219, the telescopic arm 219 begins to enter the descending surface of the track, begins to extend, and is fully extended when the second-to-last basket falls to the same height, supporting the second-to-last basket. Afterward, the roller 2192 will roll on the surface of the cam disk 2171, which is also perpendicular to the rotation axis of cam 217. Since there is no lifting surface, the telescopic arm will remain extended in this section, supporting the remaining basket stack until the second stacking begins. The lifting boom 218 and the telescopic boom 219 work together to achieve the stacking and dismantling function.

[0049] like Figure 4 As shown, in a specific embodiment of the present invention, two sets of cam mechanisms are provided on both the left and right sides of the frame. The two sets of cam mechanisms on the same side are synchronously driven by a synchronous connecting rod 210. The synchronous connecting rod 210 is a triangular frame. One corner of the synchronous connecting rod 210 is connected to the rotating shaft 207 through a crank 209. The other two corners of the synchronous connecting rod 201 are respectively connected to the rotating shaft of the cam 217 in the two sets of cam mechanisms through the crank 209.

[0050] like Figure 10 As shown, the return module 3 includes a left side plate 304, a right side plate 305, a bottom plate 306, and a roller assembly. The left side plate 304, the right side plate 305, and the bottom plate 306 form a U-shaped frame, and the roller assembly is mounted between the left side plate 304 and the right side plate 305. The roller assembly includes an electric roller 301 and a driven roller 302. The electric roller 301 is installed in the middle position and drives the driven roller 302 through a multi-wedge belt 303. When the basket sorting module 2 transports the bottom luggage basket 5 onto the roller, the electric roller starts to return the luggage basket.

[0051] like Figure 11 As shown, the housing component comprises an upper housing 401, a quick-release sealing plate 402, a guide plate 406, and sensors mounted thereon. The guide plate 406 guides the luggage baskets during collection; when the maximum storage capacity of luggage baskets in the collection device is reached, a full-stack sensor 403 is triggered, at which point the conveyor line stops supplying baskets to the collection device. A bottom-level touch sensor 404 determines whether there are still baskets in the collection device. When only one luggage basket remains, the collection device stops working and sends the basket out. A return sensor 405 detects whether the luggage basket has been completely sent out during the return process. Only when one luggage basket has been completely sent out will the basket-separating module continue to move and disassemble the baskets, while simultaneously allowing new luggage baskets to fall into the luggage basket stacking and collection device of this invention, stacked as shown in the diagram. Figure 2 As shown.

[0052] The working process of the device is as follows Figure 12 As shown. The present invention also provides a method for stacking and collecting luggage baskets using the above-described luggage basket stacking and collecting device, comprising the following steps:

[0053] 1) Start the power unit in the luggage basket stacking and collection device. The power unit rotates, which in turn drives the rotating shaft to rotate.

[0054] 2) The rotating shaft drives the synchronous connecting rod to move through a crank located at one end of the synchronous connecting rod, and the synchronous connecting rod converts the displacement into the rotation of all the cams through a crank located at the other end;

[0055] 3) The cam drives the lifting arm up and down, and the telescopic arm moves left and right in tandem. Because the roller of the telescopic arm abuts against the side of the cam with the track block under the action of the return spring, when the cam rotates and the rising surface of the roller and the track block comes into contact, the roller is squeezed. The telescopic guide block fixedly connected to the roller transmits the squeezing force to the return spring, the return spring is compressed, and the telescopic arm retracts to release the bottom luggage basket;

[0056] At the same time, the rotation of the cam causes the lifting crank to move, and the lifting crank drives the lifting arm to rise to the highest point along the linear guide rail, supporting the bottom luggage basket. At this time, the rollers travel on the flat area of ​​the track block, and the telescopic arm will always remain in the retracted state.

[0057] 4) The cam continues to rotate, and the lifting arm lowers the entire stack of luggage baskets. As the rollers pass over the lowering surface of the track block, the return spring resets, and the telescopic arm extends as the position of the rollers and the lowering surface changes. After the stack of baskets has descended to the height of one luggage basket, the telescopic arm extends to its maximum distance and begins to lift the second-to-last luggage basket.

[0058] 5) The cam continues to rotate, and the lifting arm continues to move downward, causing the bottom luggage basket to descend. At this time, the roller passes over the flat surface, and the telescopic arm remains in the same position, lifting the remaining baskets except for the bottom basket, thus completing the stacking and destacking action.

[0059] 6) Finally, the lifting arm places the bottom luggage basket onto the return module and sends the bottom luggage basket out.

[0060] 7) The luggage baskets returned by the external conveyor belt are guided by the guide plate 406 and fall into the luggage basket stacking and collection device, and the luggage baskets are stacked in sequence.

[0061] 8) The cam continues to rotate, repeating steps 3), 4), 5), 6) and 7), thereby automating the process from collecting baskets, stacking, splitting, conveying downwards, and returning.

[0062] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. Those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
