Description

Technical Field

[0001] This application relates to the field of queuing machines, and more specifically, to a queuing machine and a liveness detection system. Background Technology

[0002] At security checkpoints such as high-speed rail stations or subway stations, packages need to be inspected for live persons using a detection unit. This unit typically uses X-ray imaging to scan the internal structure of the package. In practice, queuing machines are usually paired with these detection units. Packages are placed on the queuing machine for inspection, and once the package on the detection unit has been inspected, it is then transported to the detection unit for further inspection.

[0003] Queuing machines serve a transportation function, but in existing technologies, when someone places a package on the queuing machine to be inspected, the queuing machine continues to transport the package to the inspection host. This may cause packages being inspected to be stacked together with packages awaiting inspection, thus affecting the inspection results.

[0004] A queuing machine and a liveness detection system are now provided. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section above, some embodiments of this application provide a queuing machine, comprising: a base; two first rotating shafts rotatably mounted between two side plates of the base; a second rotating shaft rotatably mounted between the two side plates of the base; a conveyor belt driven between the first and second rotating shafts; a drive motor fixedly connected to the base, with its output shaft fixedly connected to the second rotating shaft; and two photoelectric probes electrically connected to the drive motor.

[0007] When the detection host is working, the drive motor is not started. When the detection host is working, the drive motor starts under the action of the photoelectric probe, causing the output shaft of the drive motor to drive the second rotating shaft to rotate. Under the action of the conveyor belt and the first rotating shaft, the conveyor belt rotates and transports the items. Then the items are transported from the upper conveying platform to the conveyor belt and then enter the detection host for detection, avoiding pushing and shoving that may affect the detection effect.

[0008] In some embodiments, the base includes a base and two mounting seats, the two mounting seats being fixed to the base, and a first rotating shaft being rotatably mounted between the two mounting seats.

[0009] In some implementations, a support plate is fixed between the two bases, and the support plate passes through the conveyor belt and contacts the conveyor plate.

[0010] In some implementations, the support plate is U-shaped.

[0011] In some implementations, the support plate is fixed with reinforcing ribs.

[0012] In some implementations, a stabilizing rod is fixed to the base.

[0013] In some implementations, the stabilizer bars are configured as multiple bars.

[0014] In some implementations, the base is fixed to four casters at its bottom.

[0015] In some implementations, the base has four support rods threaded to its bottom.

[0016] A liveness detection system includes a queuing machine, a vibration wake-up machine, and a detection host. The queuing machine is disposed between the vibration wake-up machine and the detection host, and a photoelectric probe is electrically connected to the vibration wake-up machine and the detection host.

[0017] The beneficial effects of this application are as follows: by setting up a drive motor, conveyor belt, first rotating shaft, second rotating shaft, and photoelectric probe, the drive motor is not started when the detection host is working. When the detection host is working, the drive motor is started under the action of the photoelectric probe, so that the output shaft of the drive motor drives the second rotating shaft to rotate. Under the action of the conveyor belt and the first rotating shaft, the conveyor belt rotates and transports the items. Then, the items are transported from the upper conveying platform to the conveyor belt and then enter the detection host for detection, avoiding pushing and shoving that affects the detection effect.

[0032] Reference Figure 1-4A queuing machine includes: a base 7, a first rotating shaft 14, a second rotating shaft 16, a conveyor belt 4, a drive motor 11, and photoelectric sensors 15. Two first rotating shafts 14 are rotatably mounted between two side plates of the base 7. The second rotating shaft 16 is rotatably mounted between the two side plates of the base 7. The conveyor belt 4 is driven between the first rotating shaft 14 and the second rotating shaft 16. The drive motor 11 is fixedly connected to the base 7, and the output shaft of the drive motor 11 is fixedly connected to the second rotating shaft 16. Two photoelectric sensors 15 are provided and electrically connected to the drive motor 11.

[0033] The base 7 includes a base 6 and two mounting seats 5, which are fixedly connected to the base 6. A first rotating shaft 14 is rotatably mounted between the two mounting seats 5. A support plate 12 is fixedly connected between the two bases 6, passing through the conveyor belt 4 and contacting the conveyor belt. The support plate 12 is U-shaped. Reinforcing ribs 13 are fixedly connected to the support plate 12. A stabilizing rod 9 is fixedly connected to the base 6. Multiple stabilizing rods 9 are provided. Four casters 10 are fixedly connected to the bottom of the base 6. Four support rods 8 are threadedly connected to the bottom of the base 6.

[0034] The support plate 12 serves to support the conveyor belt 4 and prevent it from being wrapped and damaged. The reinforcing rib 13 increases the strength of the support plate 12.

[0035] When the detection host 3 is working, the drive motor 11 is not started. When the detection host 3 is working, the drive motor 11 is started under the action of the photoelectric probe 15. The output shaft of the drive motor 11 drives the second rotating shaft 16 to rotate. Under the action of the conveyor belt 4 and the first rotating shaft 14, the conveyor belt 4 rotates and transports the items. Then the items are transported from the upper conveying platform to the conveyor belt 4 and then enter the detection host 3 for detection, avoiding pushing and squeezing that may affect the detection effect.

[0036] A liveness detection system includes a queuing machine 2, a vibration wake-up device 1, and a detection host 3. The queuing machine 2 is positioned between the vibration wake-up device 1 and the detection host 3, and a photoelectric probe 15 is electrically connected to both the vibration wake-up device 1 and the detection host 3. The vibration wake-up device 1 vibrates and wakes up the package inside, then it is conveyed onto the queuing machine 2 and finally onto the detection host 3 for detection. While the detection host 3 is performing its detection, another package to be detected remains on the vibration wake-up device 1 and continues to vibrate to prevent pushing or shoving. Only after the detection is complete is the package to be detected conveyed onto the queuing machine 2.
