Description

Technical Field

[0001] This utility model relates to the field of automated sorting technology in logistics, specifically an unmanned express sorting line. Background Technology

[0002] With the popularization of online shopping and the development of the logistics industry, the volume of express delivery business is constantly increasing. The traditional manual sorting model can no longer meet the efficiency requirements. The automation and intelligent transformation of the sorting process has become an inevitable trend in the development of the logistics industry. As a result, automated sorting equipment has become the core infrastructure of warehousing centers and express transfer stations. The diversity of express packaging forms and the randomness of packaging operations have brought significant challenges to automated sorting. Existing express packaging is divided into bagged and boxed packaging. Because boxes have six sides and the labeling process is relatively random, the label is often arbitrarily affixed to any side. Due to the large number of express packages, they are placed randomly on the conveyor belt for sorting, making it impossible to ensure that all the label numbers are facing upwards, thus making it impossible to scan the labels. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an unmanned express sorting line to solve the problems mentioned in the background. This utility model has a novel structure. Through a three-layer scanning layout of a first scanner, a second scanner, and a third scanner, it achieves full-dimensional coverage of all six surfaces of boxed express packages. Regardless of which side the tracking number is affixed to or the package enters the sorting line in any posture, it can accurately identify the package, reducing sorting delays caused by tracking number orientation. From package import and scanning adjustment to sorting and collection, the entire process requires no manual intervention, improving sorting efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an unmanned express sorting line, comprising a sorting conveyor belt, the sorting conveyor belt being arranged in two sections, a barcode scanner fixedly installed between the two sections of the sorting conveyor belt, a flipping component being provided on the barcode scanner, a displacement groove extending downwards from the upper side of the barcode scanner, the flipping component comprising an L-shaped displacement plate slidably fitted between the inner walls of both sides of the displacement groove, a plurality of electric rotating plates and a plurality of guide slides fixedly connected to the rear section of the sorting conveyor belt, the electric rotating plates corresponding to the guide slides, adjacent electric rotating plates being staggered, and adjacent guide slides also being staggered, with a collection box placed at the outlet below each guide slide.

[0005] Furthermore, a plurality of conveying rollers are rotatably fitted on one side of the inner wall of the displacement groove, and a driving component that drives the plurality of conveying rollers is fixedly installed on the outer side of the barcode scanner. An L-shaped frame is fixedly connected to the upper side of the barcode scanner, and a first barcode scanner located above the conveying rollers is fixedly installed below the horizontal plate of the L-shaped frame.

[0006] Furthermore, a mounting plate is fixedly connected to one side of the barcode scanner, and a second barcode scanner is fixedly connected to the mounting plate facing the inside of the barcode scanner. The second barcode scanner is located on one side above the bottom plate of the L-shaped displacement plate. A first servo motor is fixedly installed at the bottom of the bottom plate of the L-shaped displacement plate, and a limit strip is fixedly connected to one end of the output shaft of the first servo motor that extends through to the top of the bottom plate of the L-shaped displacement plate.

[0007] Furthermore, a limiting plate is fixedly connected to the top of the limiting strip, and a third barcode scanner is fixedly installed on the upper side of the limiting plate. The third barcode scanner is located above the bottom plate of the L-shaped displacement plate.

[0008] Furthermore, a support plate is provided above the bottom plate of the L-shaped displacement plate, and multiple support columns are fixedly connected to the upper side of the support plate. The support columns are located in the gap between two adjacent conveying rollers. A through groove is provided in the middle of the support plate to slide with the limiting strip, and a spring is fixedly connected to the bottom of the support plate.

[0009] Furthermore, a slider is fixedly connected to one side of the longitudinal plate of the L-shaped displacement plate, and a sliding groove is opened outward on one side of the inner wall of the displacement groove to slide with the slider.

[0010] Furthermore, a beveled block with its beveled edge facing downwards is fixedly connected to the inner wall side of the displacement groove near the conveying roller, and the upper side of one side of the pallet abuts against the beveled edge of the beveled block.

[0011] Furthermore, a lifting groove is provided on one side of the inner wall of the displacement groove, a third servo motor is fixedly installed on the upper side of the barcode scanner, the output shaft of the third servo motor is fixedly connected to a second screw that is rotatably engaged with the inner wall of the lifting groove, a lifting block that is threadedly engaged with the second screw is slidably engaged with the inner wall of the lifting groove, a lifting frame is fixedly connected to one side of the lifting block, and a through groove that is slidably engaged with the lifting frame is provided on one side of the L-shaped displacement plate upright.

[0012] The beneficial effects of this utility model are: 1. This unmanned express sorting line achieves full-dimensional coverage of all six surfaces of boxed express packages through a three-layer barcode scanner layout consisting of a first barcode scanner, a second barcode scanner, and a third barcode scanner. It can accurately identify packages regardless of which side the tracking number is affixed to or the package enters the sorting line in any posture, reducing sorting delays caused by tracking number orientation issues. From package import and barcode adjustment to sorting and collection, the entire process requires no manual intervention, improving sorting efficiency.

[0013] 2. The unmanned express sorting line adopts a stepped scanning logic of "top surface first, then side surface, and finally bottom surface". It prioritizes scanning the top surface with a higher probability and only initiates subsequent adjustments when it is not recognized. The staggered distribution of adjacent electric turntables and guide slides allows each sorting channel to operate independently. Even if multiple express packages enter different sorting areas at the same time, there will be no channel blockage. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 6This utility model provides a technical solution: an unmanned express sorting line, including a sorting conveyor belt 1, which is arranged in two sections. A barcode scanner 2 is fixedly installed between the two sections of the sorting conveyor belt 1. A flipping component 3 is provided on the barcode scanner 2. A displacement groove 6 is opened downward through the upper side of the barcode scanner 2. The flipping component 3 includes an L-shaped displacement plate 301 that slides between the inner walls on both sides of the displacement groove 6. The rear section of the sorting conveyor belt 1 is rotatably equipped with several electric rotating plates 4 and several guide slides 5 that are fixedly connected. The electric rotating plates 4 correspond to the guide slides 5. Adjacent electric rotating plates 4 are staggered, and adjacent guide slides 5 are also staggered. A collection box is placed at the outlet below each guide slide 5.

[0018] In this embodiment, a plurality of conveying rollers 7 are rotatably fitted on one side of the inner wall of the displacement groove 6. A driving component 8 that drives the plurality of conveying rollers 7 is fixedly installed on the outer side of the barcode scanner 2. An L-shaped frame 9 is fixedly connected to the upper side of the barcode scanner 2. A first barcode scanner 10 located above the conveying rollers 7 is fixedly installed below the horizontal plate of the L-shaped frame 9. A mounting plate 11 is fixedly connected to one side of the barcode scanner 2. A second barcode scanner 12 is fixedly connected to the mounting plate 11 facing the inner side of the barcode scanner 2. The second barcode scanner 12 is located on one side above the bottom plate of the L-shaped displacement plate 301. A first servo motor 13 is fixedly installed at the bottom of the bottom plate of the L-shaped displacement plate 301. A limit strip 14 is fixedly connected to one end of the output shaft of the first servo motor 13 that extends through to the top of the bottom plate of the L-shaped displacement plate 301. A limit plate 15 is fixedly connected to the top of the limit strip 14. A third barcode scanner 16 is fixedly installed on the upper side of the limit plate 15. The third barcode scanner 16 is located above the bottom plate of the L-shaped displacement plate 301.

[0019] Specifically, the express delivery first enters the front sorting conveyor belt 1. The conveyor belt power system provides driving force to directionally transport the express delivery to the barcode scanner area 2, and finally enters the dedicated barcode scanning channel formed by the inner walls on both sides of the displacement groove 6. Inside the barcode scanning channel, several conveyor rollers 7 on one side of the inner wall of the barcode scanner 2 rotate synchronously under the drive of the drive component 8 to assist the express delivery to move smoothly in the channel and avoid jamming. At the same time, the first barcode scanner 10 installed below the horizontal plate of the L-shaped frame 9 scans the top surface of the express delivery vertically downward. If no valid tracking number is identified (it is determined that the tracking number is not attached to the top surface), the system immediately triggers the flipping component 3 to start, and enters the secondary barcode scanning adjustment stage.

[0020] In this embodiment, a support plate 302 is provided above the bottom plate of the L-shaped displacement plate 301. Multiple support columns 303 are fixedly connected to the upper side of the support plate 302. The support columns 303 are located in the gap between two adjacent conveying rollers 7. A through groove 304 is provided through the middle of the support plate 302, which slides and engages with the limiting strip 14. A spring 305 is fixedly connected to the bottom of the support plate 302. A slider 306 is fixedly connected to one side of the longitudinal plate of the L-shaped displacement plate 301. A sliding groove 307 is provided outwardly on one side of the inner wall of the displacement groove 6, which slides and engages with the slider 306. A second servo motor 308 is fixedly installed on the outer side of the barcode scanner 2. A first screw 309, which rotatably engages with the inner wall of the sliding groove 307, is fixedly connected to the output shaft of the second servo motor 308. 309 is threadedly engaged with slider 306. A beveled block 310 with its beveled edge facing downwards is fixedly connected to the inner wall of the displacement groove 6 near the conveyor roller 7. The upper side of one side of the support plate 302 abuts against the beveled edge of the beveled block 310. A lifting groove 311 is provided on one side of the inner wall of the displacement groove 6. A third servo motor 312 is fixedly installed on the upper side of the barcode scanner 2. A second screw 313 rotatably engages with the inner wall of the lifting groove 311 is fixedly connected to the output shaft of the third servo motor 312. A lifting block 314 threadedly engages with the second screw 313 is slidably engaged with the inner wall of the lifting groove 311. A lifting frame 315 is fixedly connected to one side of the lifting block 314. A through groove 316 slidably engages with the lifting frame 315 is provided on one side of the upright plate of the L-shaped displacement plate 301.

[0021] Specifically, after receiving the start command, the second servo motor 308 drives the first screw 309 connected to the output shaft to rotate in the slide groove 307. Through threaded engagement, it drives the slider 306 and the L-shaped displacement plate 301 fixed thereto to move laterally along the displacement groove 6 until the L-shaped displacement plate 301 moves to the position corresponding to the second barcode scanner 12. During this process, the L-shaped displacement plate 301 moves outward, causing the support plate 302 to break free from the inclined side constraint of the inclined block 310. The spring 305 at the bottom of the support plate 302 releases its elastic force, causing the support plate 302 and the multiple support columns 303 above it to move upward. The support columns 303 insert into the gap of the adjacent conveyor roller 7, lifting the express delivery upward until it is detached from the surface of the conveyor roller 7 and is exactly within the scanning range of the second barcode scanner 12. The first servo motor 13 starts, and its output shaft passes through the bottom plate of the L-shaped displacement plate 301 and drives the limit strip 14 to rotate. The limit strip 14 synchronously drives the support plate 302 and the express delivery above it to rotate slowly, so that the sides of the express delivery are aligned with each other in sequence. The second barcode scanner 12 facilitates a comprehensive scan of the tracking number on the side of the package. If the second barcode scanner 12 still fails to identify a valid tracking number (determining the tracking number is affixed to the bottom), the system enters a three-stage scanning adjustment phase. The second servo motor 308 continues to drive the first screw 309 to rotate, causing the L-shaped displacement plate 301 to move laterally along the displacement groove 6 until the lifting frame 315 on the inner side of the longitudinal plate of the L-shaped displacement plate 301 passes through the through groove 316 and moves to the area directly below the package on the support column 303. Subsequently, the third servo motor 312 starts, driving the second screw 313 connected to the output shaft to rotate in the lifting groove 311. Through the threaded engagement, the lifting block 314 and the lifting frame 315 rise vertically. The lifting frame 315 lifts the package from the bottom to a high position, completely exposing the bottom surface of the package. After the package is lifted to a high position, the third barcode scanner 16 (facing the bottom surface of the package) installed above the support plate 302 performs a precise scan of the bottom of the package until a valid tracking number is identified.

[0022] When the device is in use, during the operation of the unmanned express sorting line, the express package first enters the front sorting conveyor belt 1 and is driven by the conveyor belt power system to move towards the barcode scanner 2. After arriving, it enters the barcode scanning channel defined by the inner walls on both sides of the displacement groove 6. At this time, several conveyor rollers 7 on one side of the inner wall of the barcode scanner 2 rotate under the drive component 8 to assist the express package to move smoothly. At the same time, the first barcode scanner 10 installed below the horizontal plate of the L-shaped frame 9 scans from above the express package. If no valid tracking number is identified, the system triggers the flipping component 3 to start. Then, the second servo motor 308 drives the first screw 309 to rotate. The screw thread engages to move the slider 306 and L-shaped displacement plate 301 laterally along the displacement groove 6 to the corresponding position of the second barcode scanner 12. Simultaneously, as the L-shaped displacement plate 301 moves outward, the support plate 302 moves away from the inclined side of the inclined block 310. The spring 305 resets, causing the support plate 302 and the multiple support columns 303 above it to move upward, lifting the express delivery away from the conveyor roller 7 and positioning it on one side of the second barcode scanner 12. At this time, the first servo motor 13 is activated, driving the support plate 302 and the express delivery above it to rotate via the limit bar 14, making it easier for the barcode scanner 2 to scan the tracking number on the side of the express delivery. If neither of these methods detects a valid tracking number, the second servo motor 308 continues to drive the first screw 309 to rotate, causing the L-shaped displacement plate 301 to move laterally along the displacement groove 6. The lifting frame 315 on the inner side of the longitudinal plate of the L-shaped displacement plate 301 passes through the through groove 316 and is positioned below the express delivery on the support column 303. At this time, the third servo motor 312 is activated. The second screw 313 is driven to rotate, which in turn drives the lifting block 314 and the lifting frame 315 to rise, thereby lifting the express delivery to a higher position. At this time, the third barcode scanner 16 above the pallet 302 can identify and scan the valid tracking number at the bottom of the express delivery. After successful scanning, the express delivery information is transmitted to the sorting control system in real time. The system matches the corresponding guide slide 5 and electric turntable 4. When the express delivery is transported to the target sorting area, the corresponding electric turntable 4 rotates under the instruction. Through surface friction, the express delivery is driven to deviate from the guide slide 5. Because the adjacent electric turntable 4 and guide slide 5 are staggered, interference can be avoided. Finally, the express delivery slides down the guide slide 5 and falls into the corresponding collection box from the lower exit, completing the sorting process.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
