Description

Technical Field

[0001] This invention belongs to the technical field of security inspection conveying equipment, specifically relating to a passenger basket retrieval system for a side basket return line at an airport. Background Technology

[0002] Currently, passengers often need to travel by plane, train, bus, subway, and other means of transportation. To ensure passenger safety, passengers' carry-on items need to be screened by security scanners. During the security check, passengers usually need to place their carry-on items in a security basket and pass it through the scanner. In a side-return basket system, the basket returns to the passenger's retrieval position via a return line, currently located on the staff side of the security checkpoint. This method requires passengers to reach across the security checkpoint platform to retrieve the basket, which can cause difficulties for some passengers in retrieving their baskets.

[0003] Therefore, how to provide a passenger basket retrieval system that can connect the side return basket line and the security checkpoint platform is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a passenger basket retrieval system for the side return line of an airport. During passenger security checks, passengers only need to bend over slightly to retrieve the security basket and place it on the passenger storage platform, making it convenient for passengers to place their personal belongings. This solves the problems caused by passengers having to reach across the security checkpoint and storage platform to retrieve the basket, resulting in some passengers being unable to retrieve their baskets or experiencing difficulties in doing so.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a passenger basket retrieval system for a side basket return line at an airport, comprising:

[0006] The transition cabinet has a security check platform on top and a conveyor channel running through both ends inside. One end of the transition cabinet corresponding to the conveyor channel has a basket retrieval opening, and the other end of the transition cabinet corresponding to the conveyor channel has a side return basket conveyor line arranged on the outside. The arrangement direction of the side return basket conveyor line is perpendicular to the conveyor channel.

[0007] A phototube assembly, comprising a first phototube, a second phototube, and a third phototube, wherein the first and second phototubes are arranged at intervals in the conveying channel and detect the position of the security basket in the conveying channel; the first phototube is arranged close to the basket retrieval opening; the distance between the second phototube and the first phototube is greater than the length of the security basket; and the third phototube is arranged below the side return basket conveying line and detects the security basket on the conveying line.

[0008] A basket pushing mechanism is installed on the side of the side return basket conveyor line away from the security inspection platform. The basket pushing mechanism pushes the security inspection basket into the conveyor channel.

[0009] A logic controller is connected to the first phototube, the second phototube, the third phototube, and the basket-pushing mechanism via electrical signals.

[0010] The beneficial effects of this invention are: It utilizes a logic controller in conjunction with a first phototube, a second phototube, a third phototube, and a basket-pushing mechanism to control the cyclical operation of the entire system. The basket retrieval opening is located on the lower level of the security checkpoint platform, allowing passengers to easily retrieve the basket by simply bending slightly and placing it on the passenger storage platform. This facilitates the placement of personal belongings, and the baskets are replenished as needed. This solves the problems caused by passengers having to reach across the security checkpoint platform to retrieve the baskets, resulting in some passengers being unable to retrieve them or experiencing difficulties in doing so.

[0011] Preferably, a limit switch for controlling the operation of the conveyor line is arranged on the side return basket conveyor line and near the basket pushing mechanism.

[0012] The resulting technical effect is that the limit switch is used to control the operation of the side return basket conveyor line, and the limit switch is a normally open contact.

[0013] Preferably, the side return basket conveyor line is mounted on a support frame, and the top of the support frame on the side away from the transition cabinet is provided with a guide device for guiding the security basket. The third phototube is mounted on the support frame and located below between two adjacent conveyor rollers.

[0014] The resulting technical effect is that the guide device on the support frame guides the movement of the security basket, making it easy for the side-mounted security basket to be smoothly converted into a flat position.

[0015] Preferably, the basket pushing mechanism includes an electric cylinder and a push block. The electric cylinder is horizontally mounted on the support frame and located above the conveyor line. The push block is fixedly connected to the actuating end of the electric cylinder and has an inclined surface that matches the bottom surface of the security inspection basket.

[0016] The resulting technical effect is that the pusher blocks are used to push the security basket to move, allowing it to smoothly enter the conveyor channel during the movement.

[0017] Preferably, the end of the push block corresponding to the retraction stroke of the execution end abuts against the limit switch and controls the operation of the side return basket conveyor line.

[0018] The resulting technical effect is that the limit switch closes when the push block is pressed, which in turn controls the operation of the side return basket conveyor line, transporting the security basket from the previous position forward to the waiting position, which corresponds to the execution position of the push basket mechanism.

[0019] Preferably, during the basket retrieval state, if the first phototube detects no security basket, the second phototube detects no security basket, and the third phototube detects the presence of a security basket on the conveyor line, then the electric cylinder pushes the security basket on the conveyor line into the conveying channel; when the first phototube does not detect a basket but the second phototube can detect a basket, the electric cylinder continues to push forward; when the first phototube detects a basket but the second phototube does not detect a basket, the actuator end of the electric cylinder retracts to the initial state and the push block presses down the limit switch, causing the security basket on the side return basket conveyor line to be sent forward and enter the waiting state.

[0020] The resulting technical effect is that the present invention achieves the reciprocating cycle of picking up and sending baskets based on the joint control of three phototube components. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See the appendix of this invention. Figures 1 to 3 According to an embodiment of the present invention, a passenger basket retrieval system for a side basket return line at an airport includes:

[0027] The transition cabinet 1 has a security check platform on top and a conveyor channel 3 running through both ends inside. One end of the transition cabinet 1 corresponding to the conveyor channel 3 has a basket retrieval opening 2. The other end of the transition cabinet 1 corresponding to the conveyor channel 3 has a side return basket conveyor line 4 arranged on the outside. The arrangement direction of the side return basket conveyor line 4 is perpendicular to the conveyor channel 3.

[0028] The photoelectric tube assembly 5 includes a first photoelectric tube 51, a second photoelectric tube 52 and a third photoelectric tube 53. The first photoelectric tube 51 and the second photoelectric tube 52 are arranged at intervals in the conveying channel 3. The first photoelectric tube 51 is arranged on the side closer to the basket opening 2. The distance between the second photoelectric tube 52 and the first photoelectric tube 51 is greater than the length of the security basket 10. The third photoelectric tube 53 is arranged below the side return basket conveying line 4 and detects the security basket 10 on the conveying line.

[0029] The basket pushing mechanism 8 is installed on the side of the side return basket conveyor line 4 away from the security inspection platform. The basket pushing mechanism 8 pushes the security inspection basket 10 into the conveyor channel 3.

[0030] The logic controller is electrically connected to the first phototube 51, the second phototube 52, the third phototube 53, and the basket pushing mechanism 8.

[0031] In other embodiments, a limit switch 9 for controlling the operation of the conveyor line is arranged on the side return basket conveyor line 4 and near the basket pushing mechanism 8. The limit switch is a normally open contact.

[0032] In other specific embodiments, a support frame 6 is mounted on the side return basket conveyor line 4. A guide device 7 for guiding the security basket is located on the top of the support frame 6 on the side away from the transition cabinet 1. A third photoelectric tube 53 is mounted on the support frame and positioned below and between two adjacent conveyor rollers. The guide device can be a guide wheel assembly.

[0033] In some other embodiments, the basket pushing mechanism 8 includes an electric cylinder 81 and a push block 82. The electric cylinder 81 is horizontally mounted on the support frame 6 and located above the side return basket conveyor line. The push block 82 is fixedly connected to the execution end of the electric cylinder 81 and has an inclined surface that matches the bottom surface of the security inspection basket.

[0034] In some other specific embodiments, the end of the push block 82 corresponding to the retraction stroke of the execution end abuts against the limit switch 9 and controls the operation of the side return basket conveyor line 4.

[0035] In other specific embodiments, when the basket is being retrieved, the first phototube 51 detects that there is no security basket, the second phototube 52 detects that there is no security basket, and the third phototube 53 detects that there is a security basket on the conveyor line. Then, the electric cylinder 81 pushes the security basket on the conveyor line into the conveying channel. When the first phototube 51 does not detect the basket, but the second phototube 52 can detect the basket, the electric cylinder 81 continues to push forward. When the first phototube 51 detects the basket, but the second phototube 52 does not detect the basket, the actuator of the electric cylinder 81 retracts to the initial state and the push block presses down the limit switch 9, so that the security basket on the side return basket conveyor line is sent forward and enters the waiting state.

[0036] The third phototube 53 and the limit switch 9 are not for the control of the entire side return basket conveyor line. The third phototube 53 and the limit switch 9 are only for the control of the station before the push basket mechanism 8. When the third phototube 53 detects that there is no basket at the push basket station and the limit switch 9 is pressed down by the push basket mechanism, the basket at the station before the push basket mechanism 8 is controlled to be conveyed to the position of the push basket mechanism, thus completing the conveying and delivery process of the security inspection basket.

[0037] That is: when the third phototube at station one senses a basket, the baskets behind at station two stop moving forward; when the third phototube senses no basket and simultaneously the basket-pushing mechanism at station one pushes the empty basket to the basket-retrieving platform in front, retracts into place, and triggers the limit switch, only then will the empty basket at station two begin to move to station two. Figure 3 This is a plan view of the side return basket conveyor line of the entire security inspection system.

[0038] The specific control process is as follows:

[0039] Initially, there is a basket inside the basket retrieval opening, and the second phototube cannot detect the presence of a basket in its original state. When a passenger retrieves a basket from the retrieval opening, the first and second phototubes detect no basket, while the third phototube detects a basket on the conveyor line. The electric cylinder then drives a pusher block to move the security basket towards the conveyor channel. The guide device and the inclined surface on the pusher block help to place the security basket horizontally. During the pushing process, if the second phototube detects a basket but the first and third phototubes detect no basket, the pushing process is not yet complete, and the electric cylinder continues to push the pusher block. When the security basket is in position—that is, when the first phototube detects a basket and the second and third phototubes all detect no basket—the actuator of the electric cylinder retracts and eventually touches the limit switch. With the third phototube sensing no basket and the limit switch triggered, the side-return basket conveyor line moves the security basket forward. When the security basket reaches the waiting position, the third phototube detects the basket, and the side-return basket conveyor line stops, waiting for the next passenger to retrieve a basket, and the above process repeats.
