Description

Technical Field

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

[0002] In the express logistics industry, while the cargo sorting process has achieved a degree of automation, it still relies on manual labor for the delivery of parcels. However, the ability to continuously deliver parcels is relatively limited, and with rising labor costs, the need for unmanned delivery systems is becoming increasingly prominent. While the current cross-belt unmanned delivery systems in the industry have improved sorting efficiency to a certain extent, they still have many shortcomings.

[0003] Specifically, most existing unmanned parcel feeding systems use 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 modular belt type. However, due to the wide variety and irregular shapes of express parcels, when the express parcel passes through the roller-type centering machine, it may jump or stall due to the uneven surface of the centering machine, causing the express parcel to lose control and then cause missorting. When the express parcel passes the front and rear of the modular belt centering machine, it may also jump or stall due to the large turning radius, which also poses the risk of missorting. In addition, these two types of centering machines may also cause the parcel to be clamped, which significantly increases the probability of the parcel being damaged.

[0004] Existing systems typically use a balance wheel to distribute individual items. However, only a few rollers on the working surface of the balance wheel are powered, while the area outside the rollers is unpowered sheet metal. Because the roller surface is raised relative to the working surface, packages can easily stall or bounce as they pass the balance wheel, leading to uncontrolled shipments and missorting.

[0005] Furthermore, due to the limitations of the balance wheel's operating principle, the spacing between each package must be kept large to ensure accurate distribution. This requirement limits system efficiency while maintaining a constant line speed. Consequently, the industry currently generally uses two balance wheel lines to feed a single infeed area, which undoubtedly increases system complexity and cost.

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

[0064] Figure 1 The figure shows the overall structure of an embodiment of the unmanned feeding system of the present invention. Figure 1 The system of this embodiment includes the following components: a package 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] The incoming package conveyor line 1, the system's initial component, continuously conveys packages to the stacking separation unit 2. Here, the packages undergo initial separation, from stacking to de-stacking, via the collaboration of a visual inspection camera 22 and an incline-shaking accumulation conveyor 21. The separated packages then enter the single-piece separation unit 3, where a separation module 32 and a visual inspection camera 33 further ensure that the packages are properly spaced and individually delivered to the transition inlet 4.

[0066] In the transition induction section 4, packages are inspected by a light curtain 43, a grayscale meter 44, and a beam barrier 45 to ensure accurate package positioning and quality. This ensures accurate package positioning information is provided to the narrowband machine 5. Next, the packages are inducted into the narrowband machine 5, where they are centered, rejected, and distributed by a narrowband trolley 52. ​​Qualified packages are then directed to the package supply station 6.

[0067] The side-viewing light barrier 613 and position detection light curtain 614 on the package supply platform 6 precisely control the package's position. The bottom barcode scanner 615 reads the package information, and the triangular acceleration loading section 612 accelerates and precisely transfers the package to the cross belt 8. Finally, the five-sided scanner 7 on the cross belt scans the barcode on the package, completing a six-sided scan to ensure the integrity of the package information. The package then proceeds to the cross belt 8 for final sorting. Throughout the entire process, each component is closely connected and works in tandem to achieve efficient and accurate package sorting.

[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 disordered express parcels to the stack separation device 2.

[0069] Figure 2 Shown Figure 1 The stack separation device in the illustrated system embodiment is structured as follows. The stack separation device 2, located after the incoming package conveyor line 1, comprises an incline-shaking accumulation conveyor line 21, a visual inspection camera 22, and a camera-mounted profile frame 23. The stack separation device 2 is used to flatten stacked packages. The visual inspection camera 22 monitors package distribution and controls the start, stop, and speed of the incline-shaking accumulation conveyor line 21, achieving initial package separation.

[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, which allows the packages to be lifted to a certain height during the conveying process. This design helps the packages to naturally flatten under the action of gravity, facilitating subsequent separation operations.

[0072] Shaking function: During the climbing process, the conveyor line may use a specific mechanical structure (such as a vibration or shaking device) to assist in the separation of packages. 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 to ensure that the packages are delivered at a certain interval. This can control the package flow and provide a stable package supply for subsequent single-piece separation.

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

[0075] Speed Control: The distribution of packages is detected by the vision camera (2-2), and the climbing and shaking accumulation conveying line can adjust its speed to achieve effective separation of packages and control the spacing between them.

[0076] In summary, the climbing and shaking accumulation conveying line 21 in the stack separation device 2 effectively eliminates the stacking of stacked packages through climbing, shaking, accumulation, and conveying functions, achieving preliminary separation and conveying to the next processing stage.

[0077] The camera mounting profile frame 23 provides a stable mounting platform for the vision camera 22. It ensures that the camera remains stable during operation, preventing displacement due to vibration or impact, which is crucial for maintaining the accuracy and consistency of the camera's shots. In addition, the camera mounting profile frame 23 allows precise adjustment of the camera in vertical and horizontal directions to achieve the best shooting angle and field of view. This helps the camera capture complete images of the packages for effective visual detection.

[0097] Position recognition: Vision inspection cameras can identify the precise location 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 package separation process.

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

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

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

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

[0103] Figure 4 Shown Figure 1 The structure of the transition inlet section in the illustrated system embodiment. The transition inlet section 4 is located after the single-piece separation device 3 and includes a first inlet conveyor line 41, a second inlet conveyor line 42, a light curtain 43, a grayscale meter 44, and a beam barrier 45. The transition inlet section 4 guides packages into the narrowband conveyor via the first and second inlet conveyor lines 41, 42. The light curtain 43 and grayscale meter 44 detect package position and quality. The beam barrier 45 accurately detects the front and rear position of the package.

[0104] The light curtain 43, grayscale meter 44, and beam barrier 45 work together to ensure that packages are accurately detected, located, and guided in the transition induction section, providing a stable foundation for subsequent narrowband machine distribution and sorting at the infeed station. Through these detection and control measures, the system can improve infeed quality, reduce missorts, and enhance overall sorting efficiency.

The narrowband machine 5 is located after the transition inlet section 4 and comprises a narrowband frame 51, a narrowband trolley 52, a tail side conveyor line 53, and a tail DC outlet chute 54. The narrowband frame 51 is used for centering, rejecting abnormal packages, and distributing packages. Acceptable packages are moved to the side of the package supply table, while unacceptable packages are rejected by the narrowband trolley 52 via the tail side conveyor line 53 and sent to the tail side outlet or DC outlet chute 54.

[0118] Figure 6 Shown Figure 1Structure of the feed table in the illustrated system embodiment. The feed table 6, located after the narrowband machine 5, includes a triangular exit section 61, feed table accumulators 62 to 611 (where feed table accumulators 69 and 610 can be designed with dynamic weighing functionality as needed), a triangular acceleration on-car section 612, a lateral barrier gate 613, a position detection light curtain 614, and a bottom surface code scanning device 615. The feed table 6 is used to precisely transfer packages to the cross-belt, perform bottom surface barcode scanning and dynamic weighing (if needed), and accurately detect package position through the lateral barrier gate 613 and the position detection light curtain 614.

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

[0136] The lateral light barrier 613 and the position detection light curtain 614 ensure that the parcels can be accurately positioned and controlled during the conveying process on the parcel supply table, providing a stable foundation for subsequent cross belt sorting. Through these detection and control, the system can improve the quality of the supply, reduce mis-sorting, and improve the overall sorting efficiency.

[0137] The functions implemented by the lateral light barrier 613 include:

[0138] Position detection: The lateral light barrier is used to detect the lateral position of the parcels on the parcel supply table, ensuring that the parcels remain correctly aligned during the conveying process.

[0139] Tracking and sequencing: By detecting the position of the parcels in real time, the lateral light barrier can track the movement of the parcels and adjust the sequencing as needed to ensure that the parcels enter the cross belt in the correct order.

[0140] Abnormality detection: If the parcels deviate from the predetermined position, the lateral light barrier can detect this abnormality and trigger the corresponding processing mechanism, such as re-adjusting the position of the parcels or rejecting abnormal parcels.

[0141] The functions implemented 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 coordinate positions of the packages on the feeding table, providing accurate position information for the transportation and sorting of packages.

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

[0144] Efficiency optimization: The data of the position detection light curtain can help the system optimize the transportation efficiency of the packages, reduce unnecessary movement and adjustment, and improve the overall sorting speed.

[0145] The function of the bottom code scanning device 615 in the feeding table 6 mainly includes:

[0146] Barcode scanning: The bottom code scanning device is used to scan the barcode or two-dimensional code on the bottom of the package, which is an important identification in the logistics process of the package, containing the destination, recipient information and other key data of the package.

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

[0148] The cross belt 8 is connected with the feeding table 6, which is used for the final sorting of the package. The cross belt 8 is installed with a five-scan device 7, which is used for scanning the barcode except the bottom, combined with the bottom scanning of the feeding table 6, to realize six-scan.

[0149] The operation mode of the whole system is as follows:

[0150] Batch unordered express packages are transported to the stack separation device 2 through the incoming conveying line 1.

[0151] The multiple sets of vision detection cameras 22 in the stack separation device 2 will detect the specific situation of the distribution of the packages below, control the start and stop and speed of the front and rear climbing and shaking piece accumulation conveying line 21, pull the packages apart through the speed difference between the front and rear, and scatter the packages through the climbing and falling, so as to flatten the stacked packages, and then enter the single piece separation device 3.

[0152] The multiple sets of vision detection cameras 33 in the single piece separation device 3 will detect the specific situation of the distribution of the packages below, control the start and stop and speed of the corresponding separation module 32, and output the packages to the transition guide section 4 one by one at the set interval.

[0153] The package first passes through the light curtain 43, the system will calculate the specific position of the package, thereby guiding the left and right position correction of the narrow belt 5. When the package passes through the gray scale instrument 44 (the gray scale instrument can also be installed above the narrow belt), the system judges whether the package is qualified. When the package passes through the opposite light barrier 45, the system will accurately detect the front and back positions of the package for positioning the package on the narrow belt. Subsequently, the package will be guided into the narrow belt machine 5.

[0154] After the package is guided into the narrow belt machine 5, the system will adjust the positions of all qualified packages to the side close to the feeding table 6 according to the position data of the light curtain 43 and the data of whether the gray scale instrument 44 is qualified. When passing through the feeding table allocated by the system, the qualified package will be allocated to the corresponding feeding table. The positions of all unqualified packages will be adjusted to the side close to the tail side discharge port 53. When reaching the tail side discharge port 53, the unqualified package will be rejected to the side discharge port. If the package cannot be allocated to the feeding table and cannot be rejected from the side discharge port due to an abnormality, the package will be discharged from the tail straight discharge port chute 54.

[0155] After the package is allocated to the feeding table 6, the lateral opposite light barrier 613 will accurately detect the position of the package in real time and track the sorting. The bottom surface code scanning device 615 will scan the bottom surface bar code, and dynamically weigh as needed. The position detection light curtain 614 will accurately detect the front, back, left and right coordinate positions of the package. The triangular acceleration loading section 612 will accelerate the accurate transfer of the package to the corresponding trolley of the cross belt 8.

[0156] When the package passes through the five-surface scanning device 7 installed on the cross belt 8, the system will perform bar code scanning except for the bottom surface. Combined with the bottom surface scanning of the feeding table, six-surface scanning of the package can be realized. The package can be effectively scanned regardless of the position of the bar code (the six-surface scanning of each feeding table can also be designed). Finally, the package will be sorted by the cross belt 8.

[0157] The foregoing description of the present disclosure has been provided for the purpose of enabling any person skilled in the art to make or use the present disclosure. Various modifications to the present disclosure will be apparent to those skilled in the art, and the generic principles defined herein can be applied to other variations without departing from the spirit or scope of the present disclosure. Thus, the present disclosure is not intended to be limited to the examples and designs described herein, but is to be granted the broadest scope consistent with the principles and novel features disclosed herein.
