Description

Technical Field

[0001] The present invention relates to the field of express logistics, and in particular to an unmanned cross-belt feeding system. Background Art

[0002] In the express logistics industry, although the sorting process of goods has achieved a certain degree of automation, it still relies on manual feeding operations. However, the ability of manual continuous feeding is relatively weak, and with the continuous increase in labor costs, the demand for unmanned feeding systems has become increasingly prominent. At present, although the cross-belt unmanned feeding system in the industry has improved the sorting efficiency to a certain extent, it still has many shortcomings.

[0003] Specifically, most of the existing unmanned parcel feeding systems adopt two sets of single-channel single-piece separation or one set of dual-channel single-piece separation, and use a centering machine to achieve the centering function. Centering machines are mainly divided into two types: roller type and module belt type. However, due to the wide variety and irregular shapes of express parcels, when express parcels pass through the roller-type centering machine, they may jump or stall due to the uneven surface of the centering machine, causing the express parcel to lose control and cause misclassification. When the express parcel passes the head and tail of the module belt centering machine, it may also jump or stall due to the large turning radius, and there is also a risk of misclassification. In addition, these two types of centering machines may also cause clamping, which significantly increases the probability of damage to the express parcel.

[0004] In terms of the distribution of single items, existing systems usually use a balance wheel. However, only a few rollers on the working surface of the balance wheel are powered, and the area outside the rollers is a sheet metal part without power. Since the roller surface is higher than the working surface, the express is prone to stall or jump when passing the balance wheel, causing the express to lose control and then cause misclassification.

[0005] In addition, due to the limitation of the working principle of the balance wheel, the distance between each express needs to be kept large to ensure that the balance wheel can accurately distribute. This requirement limits the improvement of system efficiency when the line speed remains unchanged. Therefore, the industry currently generally uses two balance wheel lines to realize the feeding of one feeding area, which undoubtedly increases the complexity and cost of the system.

[0006] In summary, the existing cross-belt unmanned feeding system has problems such as low efficiency, poor feeding quality and high cost. Summary of the invention

[0007] A brief summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceived aspects, and is neither intended to identify the key or critical elements of all aspects nor to define the scope of any or all aspects. Its only purpose is to give some concepts of one or more aspects in a simplified form as a prelude to a more detailed description that will be given later.

[0008] The purpose of the present invention is to solve the above problems and provide an unmanned feeding system, which greatly improves the feeding quality and efficiency and reduces the cost and energy consumption.

[0009] The technical solution of the present invention is as follows: The present invention discloses an unmanned package feeding system, which includes: a package incoming material conveying line, a stacked piece separation device, a single piece separation device, a transition introduction section, a narrow belt machine, a package feeding platform, and a cross belt, wherein:

[0010] The incoming parcel conveyor line is located at the front end of the system and is used to convey batches of unordered express parcels to the stacking separation device;

[0011] The stacking separation device is located after the package incoming conveyor line, and includes a visual inspection camera of the stacking separation device and a matching multi-stage climbing accumulation conveyor line. The visual inspection camera detects the distribution of packages, controls the start and stop and speed of the multi-stage climbing accumulation conveyor line, flattens the stacked packages, and realizes the initial separation of packages.

[0012] The single piece separation device is located after the stacked piece separation device to ensure that the packages are output to the transition introduction section at a set interval;

[0013] The transition introduction section is located after the single-piece separation device, and includes a first introduction section conveyor line, a second introduction section conveyor line, a light curtain, a grayscale meter, and a beam grating, wherein the transition introduction section is used to guide the package into the narrow-band machine through the first introduction section conveyor line and the second introduction section conveyor line, and detect the position and quality of the package through the light curtain and the grayscale meter, and the beam grating is used to accurately detect the front and rear positions of the package;

[0014] The narrowband machine is located after the transition introduction section, and includes a narrowband machine frame, a narrowband trolley, a tail side discharge conveyor line, and a tail DC discharge outlet chute. The narrowband machine is used for centering, abnormal rejection, and distribution of packages. Qualified packages are adjusted to the side of the package supply platform, and unqualified packages are rejected by the narrowband trolley through the tail side discharge conveyor line to the tail side discharge outlet or DC discharge outlet chute;

[0015] The package supply platform is located behind the narrow-belt machine and includes a triangular lead-out section, a package supply platform accumulation section, a triangular acceleration loading section, a side-facing light barrier, a position detection light curtain and a bottom surface code scanning device. The package supply platform is used to transfer packages to the cross belt, scan the bottom surface code, and detect the package position through the side-facing light barrier and the position detection light curtain.

[0016] According to an embodiment of the unmanned parts feeding system of the present invention, the stacked parts separating device further comprises a climbing, shaking and accumulating conveying line and a camera mounting profile frame of the stacked parts separating device.

[0017] According to one embodiment of the unmanned parcel supply system of the present invention, the climbing and shaking accumulation conveyor line is used to lift parcels up the slope. By controlling the speed and start and stop of the conveyor line and assisting the separation of parcels through shaking during the climbing process, the stacked parcels are controlled to de-stack and be conveyed out, so as to provide parcel supply for subsequent single piece separation.

[0018] According to an embodiment of the unmanned part feeding system of the present invention, the single-piece separation device includes a single-piece separator, a separation module, a visual inspection camera of the single-piece separation device, and a camera mounting profile frame of the single-piece separation device.

[0019] According to one embodiment of the unmanned parcel feeding system of the present invention, the single piece separator is used to ensure that the parcels are separated and conveyed individually, the separation module is used to separate the continuously flowing parcels one by one, and the visual inspection camera is used to monitor and inspect the parcels passing through the single piece separation device.

[0020] According to an embodiment of the unmanned feeding system of the present invention, the light curtain, the grayscale meter and the reflected light barrier work together to control the detection, positioning and guidance of the package in the transition introduction section.

[0021] According to an embodiment of the unmanned package feeding system of the present invention, the lateral light barriers and position detection light curtains manipulate the positioning and control of packages during the conveying process on the package feeding table, providing a basis for subsequent cross-belt sorting.

[0022] According to an embodiment of the unmanned feeding system of the present invention, the incoming package conveyor line is the starting part of the system, which continuously conveys the packages to the stacking separation device. In the stacking separation device, the packages are initially separated from stacking to single pieces through the cooperation of the visual inspection camera and the climbing shaking piece accumulation conveyor line. The separated packages then enter the single piece separation device, where the separation module and the visual inspection camera ensure that the packages are output to the transition introduction section individually with appropriate spacing and status;

[0023] In the transition induction section, the packages are inspected by the light curtain, grayscale meter and reflected light barrier to provide the narrowband machine with accurate package positioning information. Then, the packages are inducted into the narrowband machine and centered, abnormal packages are removed and distributed by the narrowband trolley. Qualified packages are guided to the package supply table.

[0024] The side-to-side light grid and position detection light curtain on the package supply platform control the position of the package. The bottom surface scanning device reads the package information and accelerates and accurately transfers the package to the cross belt through the triangular acceleration loading section. The five-sided scanning device on the cross belt scans the barcode of the package to complete the six-sided scanning of the package to ensure the integrity of the package information. The package is then finally sorted by the cross belt.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the system of the present invention adopts a narrowband machine in combination with a light curtain to center the express, and adopts a narrowband for distribution. Since the narrowband surface is flat, it will not cause skipping or stalling, so the control effect is greatly improved, thereby improving the quality of the supply and reducing misclassification. In addition, the use of a small-pitch narrowband machine can reduce the distance between express items, so the efficiency can be greatly improved at the same line speed. The present invention only requires a single-channel stacking separation device and a single-piece separation device in combination with a narrowband to exceed the current general solutions in the industry, which can greatly reduce costs, achieve halving of energy consumption, low noise, high efficiency, and greatly improve the quality of supply.

[0064] Figure 1 The overall structure of an embodiment of the unmanned feeding system of the present invention is shown. Figure 1 The system of this embodiment includes the following components: a package incoming material conveyor line 1, a stacked piece separation device 2, a single piece separation device 3, a transition introduction section 4, a narrow belt machine 5, a package supply platform 6, and a cross belt 8.

[0065] As the starting part of the system, the incoming package conveyor line 1 is responsible for continuously conveying the packages to the stacking separation device 2, where the packages are initially separated from stacking to destacking through the cooperation of the visual inspection camera 22 and the climbing shaking piece accumulation conveyor line 21. Subsequently, the separated packages enter the single piece separation device 3, where the separation module 32 and the visual inspection camera 33 further ensure that the packages are output individually to the transition introduction section 4 with appropriate spacing and status.

[0066] In the transition introduction section 4, the package is detected by the light curtain 43, the grayscale meter 44 and the reflected light barrier 45 to ensure the accurate position and quality of the package, and provide accurate package positioning information for the narrowband 5. Then, the package is introduced into the narrowband machine 5, where it is centered, abnormally rejected and distributed by the narrowband trolley 52, and the qualified package is guided to the package supply station 6.

[0067] The side-to-side grating 613 and position detection light curtain 614 on the package supply platform 6 accurately control the position of the package, the bottom surface scanning device 615 reads the package information, and accelerates and accurately transfers the package to the cross belt 8 through the triangular acceleration loading section 612. Finally, the five-sided scanning device 7 on the cross belt scans the barcode of the package, completes the six-sided scanning of the package, and ensures the integrity of the package information. After that, the package is finally sorted by the cross belt 8. In the whole process, various components are closely connected and work together to achieve efficient and accurate sorting of packages.

[0068] The incoming parcel conveyor line 1 is the input part of the system, located at the front end of the system, and is used to convey batches of unordered express parcels to the stacking separation device 2.

[0069] Figure 2 Shows Figure 1 The structure of the stacked piece separation device in the system embodiment shown. The stacked piece separation device 2 is located after the package incoming conveyor line 1, and includes a climbing shaking piece accumulation conveyor line 21, a visual inspection camera 22, and a camera mounting profile frame 23. The stacked piece separation device 2 is used to flatten the stacked packages, detect the distribution of the packages through the visual inspection camera 22, control the start and stop and speed of the climbing shaking piece accumulation conveyor line 21, and realize the preliminary separation of the packages.

[0070] The functions of the climbing shaking piece accumulation conveyor line 21 in the stacked piece separation device 2 mainly include:

[0071] Climbing function: The conveyor line is designed with a climbing section, so that the package can be lifted to a certain height during the conveying process. This design helps the package to be naturally flattened under the action of gravity, which is convenient for subsequent separation operations.

[0072] Shaking function: During the climbing process, the conveyor line may assist in the separation of packages through a specific mechanical structure (such as a vibration or shaking device). This shaking can help break up the stacked packages so that they can be arranged individually on the conveyor line.

[0073] Accumulation function: The conveyor line can accumulate a certain number of packages within a certain interval, and then control the speed and start and stop of the conveyor line so that the packages are conveyed out at a certain interval. This can control the flow of packages and provide a stable package supply for subsequent single-piece separation.

[0074] Conveying function: The basic conveying function is to move the package from one place to another. In the stacking separation device, the climbing shaking accumulation conveyor line is responsible for conveying the package from the incoming material conveyor line to the single piece separation device.

[0075] Speed ​​control: By detecting the distribution of packages through a visual inspection camera (2-2), the ramp-type shaking accumulation conveyor line can adjust its speed to achieve effective separation of packages and control the spacing between packages.

[0076] In general, the climbing and shaking accumulation conveyor line 21 in the stacked package separation device 2 can effectively eliminate the stacking of the stacked packages, achieve preliminary separation and convey them to the next processing stage through functions such as climbing, shaking, accumulation and conveying.

[0077] The camera mounting profile 23 provides a stable mounting platform for the visual inspection camera 22. It ensures that the camera remains stable during operation and prevents displacement caused by vibration or shock, which is essential to maintain the accuracy and consistency of the camera's shooting. In addition, the camera mounting profile 23 allows the camera to be precisely adjusted in the vertical and horizontal directions to obtain the best shooting angle and field of view. This helps the camera capture a complete image of the package for effective visual inspection.

[0078] Figure 3 Shows Figure 1 The structure of the single-piece separation device in the system embodiment shown. The single-piece separation device 3 is located after the stack separation device 2, and includes a single-piece separator 31, a separation module 32, a visual inspection camera 33 and a camera mounting profile frame 34. The single-piece separation device 3 further ensures that the packages are output to the transition introduction section 4 at a set interval.

[0079] In the single-piece separation device 3, the single-piece separator 31 is used to further process the packages after stacking and separation, ensuring that each package can enter the transition introduction section 4 with appropriate spacing and state, so as to prepare for subsequent narrowband machine allocation and package supply station sorting.

[0080] The main functions of the single piece separator 31 include:

[0081] Single-piece separation: The main function of the single-piece separator is to ensure that the packages are separated and conveyed one by one. It controls the spacing between packages to ensure that each package can enter the next processing stage independently, avoiding errors or confusion caused by multiple packages entering at the same time.

[0082] Speed ​​control: The single-piece separator can adjust its conveying speed to match the output speed of the upstream stack separator and the processing capacity of the downstream transition inlet section to ensure the smooth operation of the entire feeding system.

[0083] Position adjustment: The single-piece separator may have the function of adjusting the position of the package on the conveyor line to ensure that the package enters the subsequent inspection and sorting process with the correct posture and direction.

[0084] Anomaly detection: In some designs, the single-piece separator may be integrated with a visual inspection camera (3-3) to detect the distribution and status of the packages and identify and reject unqualified packages, such as those that are damaged or do not meet the standard size.

[0085] Conveying stability: The single-piece separator ensures the stability of the package during conveying through its conveying mechanism, such as rollers, belts or chains, reduces the jumping or rolling of the package during conveying, and improves the quality of the supplied parts.

[0086] In the single-piece separation device 3, the separation module 32 is a key component for achieving efficient and accurate separation of packages. It provides a stable foundation for the subsequent supply and sorting processes by controlling the flow of packages.

[0087] The functions of the separation module 32 mainly include:

[0088] Package separation: The main function of the separation module is to separate the continuously flowing packages one by one, ensuring that each package can enter the subsequent transportation and processing stage individually and in sequence.

[0089] Gap Control: By precisely controlling the gap between packages, the separation module helps maintain a stable and predictable flow of packages, which is critical for subsequent visual inspection and sorting processes.

[0090] Stable conveying: The separation module is designed to convey the packages stably, reducing shaking or tumbling during conveying, which helps to improve the accuracy of feeding and reduce the risk of package damage.

[0091] Speed ​​matching: The separation module can adjust its operating speed to match the output speed of the upstream stack separation device to ensure smooth operation of the entire feeding system.

[0092] Exception handling: In some designs, the separation module may have the function of detecting abnormal packages, such as identifying packages that do not meet the standards in size, shape or weight through sensors or visual systems, and taking appropriate handling measures.

[0093] The visual inspection camera 33 and the camera mounting profile frame 34 play a key role in the single piece separation device 3, and together they ensure the accuracy and reliability of the package separation process.

[0094] The functions implemented by the visual inspection camera 33 mainly include:

[0095] Package Inspection: Visual inspection cameras are used to monitor and inspect packages passing through the single-piece separation device. It can capture images of the package and provide visual data for subsequent analysis.

[0096] Quality control: By analyzing images of packages, visual inspection cameras can identify features such as size, shape, color, and whether a package is damaged, contaminated, or otherwise defective, thereby enabling quality control.

[0097] Position recognition: Vision inspection cameras can identify the precise position of packages on the conveyor line, which is crucial for controlling the separation and subsequent processing of packages.

[0098] Data Feedback: The data collected by the visual inspection camera can be fed back to the control system to adjust the operating parameters of the separation module 32 to optimize the separation process of the packages.

[0099] Abnormal alarm: If an abnormal package is detected, the visual inspection camera can trigger an alarm to notify the system to take appropriate treatment measures, such as rejecting or redirecting the package.

[0100] The functions of the camera mounting profile frame 34 include:

[0101] Stable mounting: Provides a stable and sturdy mounting platform for the visual inspection camera to ensure that the camera will not shift due to vibration or shock during operation.

[0102] Precise Positioning: The profile mount allows for precise positioning and angle adjustment of the camera to obtain the best shooting viewing angle and coverage.

[0103] Figure 4 Shows Figure 1 The structure of the transition introduction section in the system embodiment shown. The transition introduction section 4 is located after the single-piece separation device 3, and includes a first introduction section conveyor line 41, a second introduction section conveyor line 42, a light curtain 43, a grayscale meter 44 and a beam grating 45. The transition introduction section 4 is used to guide the package into the narrowband machine through the first introduction section conveyor line 41 and the second introduction section conveyor line 42, and detect the position and quality of the package through the light curtain 43 and the grayscale meter 44, and the beam grating 45 is used to accurately detect the front and rear positions of the package.

[0104] The light curtain 43, the grayscale meter 44 and the reflected light barrier 45 work together to ensure that the parcel can be accurately detected, located and guided in the transition introduction section, providing a stable foundation for the subsequent narrowband machine allocation and the sorting of the package supply station. Through these detection and control, the system can improve the quality of the supply, reduce misclassification, and improve the overall sorting efficiency.

[0105] The functions realized by the light curtain 43 mainly include:

[0106] Position detection: The light curtain is used to detect the lateral position of the package to ensure that the package is centered when entering the narrowband machine (5).

[0107] Guided deviation: By detecting the position of the package, the system can guide the narrow belt to correct the left and right position to ensure the correct alignment of the package.

[0108] Data provision: The package position data provided by the light curtain is used to control the decision-making of the control system, such as adjusting the position of the narrow-band trolley 52.

[0109] The functions realized by Grayscale 44 mainly include:

[0110] Quality inspection: Grayscale is used to detect the color and grayscale level of the package surface to identify whether the package is damaged, contaminated or has other surface defects.

[0111] Qualification judgment: Through the detection of the grayscale instrument, the system can determine whether the package meets the quality standards, thereby deciding whether the package will continue the process or be rejected.

[0112] Installation location: The grayscale meter can be installed above the transition lead-in section or above the narrow band. The specific location depends on the system design.

[0113] The functions realized by the beam grating 45 mainly include:

[0114] Precise positioning: The through-beam grating is used to accurately detect the front and rear positions of the package, providing data support for the positioning of the package on the narrow band.

[0115] Spacing control: Through the package position information detected by the beam grating, the system can control the spacing between packages to ensure the correct distribution of packages on the narrowband machine.

[0116] Synchronous control: Data from the through-beam encoder can be used to synchronize the speed and position of narrow belt and other conveying equipment to achieve efficient package handling.

[0117] Figure 5 Shows Figure 1 The structure of the narrowband machine in the system embodiment shown. The narrowband machine 5 is located after the transition introduction section 4, and includes a narrowband frame 51, a narrowband trolley 52, a tail side discharge conveyor line 53 and a tail DC discharge outlet chute 54. The narrowband frame 51 is used for centering, abnormal rejection and distribution of packages. Qualified packages are adjusted to one side of the package supply platform, and unqualified packages are rejected by the narrowband trolley 52 through the tail side discharge conveyor line 53 to the tail side discharge outlet or the DC discharge outlet chute 54.

[0118] Figure 6 Shows Figure 1The structure of the package supply station in the system embodiment shown. The package supply station 6 is located after the narrow belt machine 5, and includes a triangular lead-out section 61, a package supply station stacking 62 to 611 (wherein the package supply station stacking 69 and 610 can be designed to have a dynamic weighing function as required), a triangular acceleration loading section 612, a side-to-side grating 613, a position detection light curtain 614, and a bottom surface code scanning device 615. The package supply station 6 is used to accurately transfer the package to the cross belt, perform bottom surface code scanning and dynamic weighing (if necessary), and accurately detect the package position through the side-to-side grating 613 and the position detection light curtain 614.

[0119] The triangular lead-out section 61 is used to ensure a smooth transition of the parcels from the package supply platform 6 to the cross belt 8, while providing control for the precise sorting of the parcels.

[0120] Package supply stations 62 to 611 are used to ensure the orderly flow and temporary storage of packages before entering the cross belt, while providing preparation and control for the final sorting of packages. Its main functions include:

[0121] Parcel temporary storage: The parcel supply platform accumulation area is used to temporarily store the separated and prepared parcels, waiting to be allocated to the cross belt 9 for sorting.

[0122] Sorting: The accumulation area can sort packages to ensure they enter the cross belt in a specific order to meet sorting strategies and needs.

[0123] Dynamic adjustment: The package supply platform can dynamically adjust the distribution of packages in the accumulation area according to the real-time demand of the cross belt to optimize the sorting efficiency.

[0124] Buffer: The accumulation area acts as a buffer zone to absorb the impact of changes in sorting line speed or fluctuations in cross-belt processing capacity, reducing interruptions in package flow.

[0125] Exception handling: In the accumulation area, the system can identify and handle abnormal packages, such as packages that do not match the size, are damaged, or have unrecognizable barcodes.

[0126] Dynamic weighing (e.g. for package supply stations 69 and 610): If the package supply station is designed with dynamic weighing function, certain parts of the accumulation area (such as 69 and 610) can weigh the packages for more accurate sorting or billing.

[0127] Barcode scanning identification: The package supply and storage area may be equipped with a barcode scanning device to scan the barcode before the package enters the cross belt to obtain the package information.

[0128] Precise control: The design of the accumulation area allows the system to precisely control the flow of packages, ensuring that packages enter the cross belt at the scheduled time and location.

[0129] The functions of the triangular acceleration loading section 612 in the bag supply platform 6 mainly include:

[0130] Speed ​​​​up: The triangular acceleration loading section is designed to gradually increase the conveying speed of the parcels from the supply platform to the cross belt to match the running speed of the cross belt.

[0131] Smooth transition: Through the triangular acceleration design, the package can smoothly transition from the conveying speed of the package supply table to the higher speed of the cross belt, reducing the impact or damage of the package caused by sudden speed changes.

[0132] Precise control: The triangular acceleration loading section allows the system to more accurately control the delivery speed and acceleration of the package, ensuring that the package can enter the cross belt at the appropriate speed and posture.

[0133] Direction adjustment: During the process of conveying the parcel from the supply platform to the cross belt, the triangular acceleration loading section may also need to adjust the direction of the parcel to ensure that it is consistent with the conveying direction of the cross belt.

[0134] Buffering effect: Between the package supply platform and the cross belt, the triangular acceleration loading section can serve as a buffer zone to reduce the impact and vibration of the package during transportation and protect the package from damage.

[0135] Dynamic adjustment: The design of the triangular acceleration loading section enables the system to dynamically adjust the acceleration process of the package according to the real-time demand of the cross belt to optimize the sorting efficiency.

[0136] The side-to-side grating 613 and the position detection light curtain 614 ensure that the parcel can be accurately positioned and controlled during the transportation process on the package supply platform, providing a stable foundation for the subsequent cross-belt sorting. Through these detection and control, the system can improve the quality of the supply, reduce missorting, and improve the overall sorting efficiency.

[0137] The functions implemented by the side beam grating 613 include:

[0138] Position detection: Lateral light barriers are used to detect the lateral position of the package on the supply table to ensure that the package remains correctly aligned during transportation.

[0139] Tracking and sorting: By detecting the location of the package in real time, the side beam barrier can track the movement of the package and make sorting adjustments when necessary to ensure that the packages enter the cross belt in the correct order.

[0140] Anomaly detection: If a package deviates from the predetermined position, the side-beaming light barrier can detect this anomaly and trigger the corresponding processing mechanism, such as re-adjusting the package position or removing the abnormal package.

[0141] The functions realized by the position detection light curtain 614 include:

[0142] Precise positioning: The position detection light curtain is used to accurately detect the front, back, left, and right coordinates of the package on the package supply table, providing accurate position information for the delivery and sorting of the package.

[0143] Dynamic adjustment: Based on the data provided by the position detection light curtain, the control system can dynamically adjust the delivery path of the package to ensure that the package can accurately enter the designated position of the cross belt.

[0144] Efficiency optimization: Data from position detection light curtains can help the system optimize the efficiency of package delivery and increase overall sorting speed by reducing unnecessary movement and adjustments.

[0145] The functions of the bottom surface scanning device 615 in the package supply station 6 mainly include:

[0146] Barcode scanning: The bottom scanning device is used to scan the barcode or QR code on the bottom of the package, which is an important identifier of the package in the logistics process and contains key data such as the destination and recipient information of the package.

[0147] Information acquisition: By scanning the barcode, the system can obtain relevant information of the package, such as the express number, destination code, etc. This information is crucial for the automatic sorting and tracking of the package.

[0148] The cross belt 8 is connected to the package supply platform 6 for final package sorting. A five-sided scanning device 7 is installed on the cross belt 8. The five-sided scanning device 7 is used to perform barcode scanning except the bottom surface, and combined with the bottom surface scanning of the package supply platform 6, six-sided scanning is achieved.

[0149] The whole system works like this:

[0150] Batches of unordered express parcels are transported to the stacking separation device 2 via the incoming material conveyor line 1.

[0151] The multiple groups of visual inspection cameras 22 in the stacked piece separation device 2 will detect the specific distribution of the packages below, control the start and stop and speed of the climbing and shaking piece accumulation conveyor line 21 below, pull the packages apart through the speed difference between the front and back, and break up the packages by climbing and falling, so as to flatten the stacked packages and then enter the single piece separation device 3.

[0152] The multiple groups of visual inspection cameras 33 in the single-piece separation device 3 will detect the specific distribution of the packages below, control the start and stop and speed of the corresponding separation module 32, and output the packages one by one to the transition introduction section 4 according to the set spacing.

[0153] The package first passes through the light curtain 43, and the system will calculate the specific position of the package, thereby guiding the narrow band 5 to correct the left and right position. When the package passes through the grayscale meter 44 (the grayscale meter can also be installed above the narrow band), the system determines whether the package is qualified. When the package passes through the reflected light grating 45, the system will accurately detect the front and rear positions of the package for positioning the package on the narrow band, and then the package will be introduced into the narrow band machine 5.

[0154] After the parcel is introduced into the narrowband machine 5, the system will adjust the positions of all qualified parcels to the side close to the parcel supply table 6 according to the position data of the light curtain 43 and the qualified data of the grayscale meter 44. When passing the parcel supply table assigned by the system, it will be assigned to the corresponding parcel supply table, and the positions of all unqualified parcels will be adjusted to the side close to the tail side discharge port 53. When reaching the tail side discharge port 53, it will be rejected to the side discharge port. If it encounters an abnormal situation that it cannot be assigned to the parcel supply table and is not rejected from the side discharge port, the parcel will be discharged from the tail DC discharge port chute 54.

[0155] After the parcel is allocated to the parcel supply platform 6, the side-projection grating 613 will accurately detect the parcel position in real time and track and sort it. The bottom bar code will be scanned by the bottom bar code scanning device 615, and dynamic weighing will be performed as needed. The position detection light curtain 614 will accurately detect the front, back, left and right coordinates of the parcel, and accelerate and accurately transfer it to the corresponding trolley of the cross belt 8 through the triangular acceleration loading section 612.

[0156] When the parcel passes through the five-sided scanning device 7 installed on the cross belt 8, the system will scan the barcode on all sides except the bottom side. Combined with the bottom side scanning of the package supply station, the parcel can be scanned on six sides. No matter where the barcode is, the parcel can be effectively scanned (it can also be designed that each package supply station has a separate six-sided scanning). Finally, the parcel will be sorted by the cross belt 8.
