Description

Technical Field

[0001] This utility model relates to the field of express delivery sorting technology, and in particular to a sorting device for small parcels. Background Technology

[0002] The sorting wall is used for small parcel sorting in the express delivery and e-commerce industries. It replaces manual operation with an automated sorting process, enabling rapid parcel classification, significantly improving sorting efficiency and reducing labor costs.

[0003] In the prior art, Chinese utility model patent application number CN202323661146.4 discloses an intelligent seeding wall sorting device, including a frame, a sorting cart, a translation component and a lifting component. By using the lifting component and the translation component, the device can automatically move the goods to the designated turnover box and transport the goods into the turnover box through the sorting cart, replacing manual sorting. It has certain advantages in terms of sorting accuracy and labor saving.

[0004] However, this technology still has obvious shortcomings in practical applications. The volume of each turnover box is limited. When the corresponding type of express is full, the machine must be stopped and a new turnover box must be replaced before sorting can continue, which reduces the overall sorting efficiency and affects the continuity of operations.

[0005] In summary, we propose a sorting device for small parcels to address the aforementioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a sorting device for small packages. By using this device, the problem of poor operational continuity in the aforementioned background technology can be solved.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] like Figures 1-3 As shown, a small package sorting device includes a frame 1. A control cabinet 11 is installed on one side of the frame 1. The control cabinet 11 has a control screen and multiple control buttons on its panel. The control cabinet 11 integrates an electrical control and network module, a network module, and a human-machine interface module, serving as the control core of the device. The control screen can display equipment operating parameters, currently processed package information, and fault alarm prompts in real time. The control buttons support device start / stop, emergency stop, sorting rule adjustment, and temporary storage channel switching. The device is equipped with a UPS uninterruptible power supply system to protect important data such as operating parameters. It also has short-circuit, overvoltage, and overcurrent protection systems to ensure the safety of equipment and personnel. A sorting cart 2 is installed inside the frame. The frame 1 also has a lifting assembly 3 for lifting the sorting cart 2, which drives the lifting assembly 3 and the sorting cart. The sorting vehicle 2 is composed of a translation component 4, a lifting component 3, and a multi-axis motion module. The power module is driven by a servo drive and automatically plans the running trajectory through position feedback and algorithms to achieve precise positioning and silent transmission of the sorting vehicle 2 in three-dimensional space. It automatically allocates sorting tasks. The front middle of the frame 1 has a sorting outlet 5, which is the output channel for sorting packages to external turnover boxes. A sorting inlet 6 is opened on one side of the sorting outlet 5, which is the package entry channel. An input component 7 is installed at the sorting inlet 6 to transport packages to the sorting vehicle 2. A temporary storage component 8 is set above the input component 7. When the turnover box is full, the corresponding package can be temporarily stored in the temporary storage component 8. The sorting vehicle 2 is equipped with a photoelectric detection device 9 for detecting the loading status of the turnover box.

[0021] Furthermore, the input component 7 includes a bracket 71, which is fixedly installed at the inlet 6. A conveyor belt 72 for transporting packages is installed on the top of the bracket 71. The output end of the conveyor belt 72 corresponds to the receiving area of ​​the sorting vehicle 2. The output end of the conveyor belt 72 is connected to the receiving area of ​​the sorting vehicle 2 to ensure that the package falls smoothly into the sorting vehicle 2.

[0022] Furthermore, the temporary storage component 8 includes a second support 81, which is fixedly connected to the outer side 72 of the first conveyor belt at the top of the first support 71. Multiple second conveyor belts 82 are installed at intervals along the height direction of the second support 81, utilizing the height space to achieve a multi-layer layout and forming multiple independent buffer units, which can buffer packages of different batches or different destinations respectively. Moreover, the output end of each second conveyor belt 82 corresponds to the receiving area of ​​the sorting vehicle 2, ensuring the mutual transfer of packages between the sorting vehicle 2 and the second conveyor belt 82.

[0023] Furthermore, each conveyor belt 82 is equipped with a baffle 83 above the end away from the frame 1. The baffle 83 is fixedly connected to the corresponding support 81 via a connecting rod. The baffle 83 can effectively prevent the package from falling from the end due to inertia or vibration.

[0024] Furthermore, the length of conveyor belt 2 82 is shorter than that of conveyor belt 1 72, making it easier for staff to place small packages on conveyor belt 1 72 for transport. A vision camera 10 is installed above conveyor belt 1 72, and the vision camera 10 is fixedly connected to the bracket 2 81 below conveyor belt 2 82 by a connecting rod. The vision camera 10 automatically scans the barcode or QR code on the surface of the package, collects key information such as destination and tracking number, and transmits it to the control cabinet 11 in real time. The control cabinet 11 matches the corresponding target turnover box according to the information.

[0025] Furthermore, the photoelectric detection device 9 is installed on the front of the top of the sorting cart 2 on the side away from the sorting entrance 6. The photoelectric detection device preferably uses a TOF laser diffuse reflection sensor to ensure that the sorting cart 2 can preferentially scan the passing turnover boxes in the round-trip path.

[0026] Working principle: Staff push the parcel storage rack (the storage rack has a multi-layer structure, with multiple turnover boxes arranged on each layer, and multiple casters installed on the bottom of the storage rack) to the sorting exit 5 of the rack body 1, ensuring that the multiple turnover boxes on each layer of the storage rack correspond to the sorting path of the sorting exit 5. Staff place the small packages to be sorted on the top of the bracket 71 of the input component 7. The packages are transported to the sorting entrance 6 by the conveyor belt 72. During the transport process, the vision camera 10 above the conveyor belt 72 automatically scans the barcode or QR code on the surface of the package, collects key information such as destination and tracking number, and transmits it to the control cabinet 11 in real time. The control cabinet 11 matches the corresponding target turnover box according to the information and completes the sorting path planning.

[0027] If the target tote is in normal condition, the package is directly transported to the receiving area of ​​the sorting vehicle 2 via conveyor belt 72 and received. If the target tote is full, the control cabinet 11 instructs the lifting component 3 to drive the sorting vehicle 2 to rise and connect with the idle conveyor belt 82 in the temporary storage component 8. The conveyor belt 82 rotates a set distance under the drive of the motor to temporarily store the package on the surface of the conveyor belt. The baffle 83 can prevent the package from falling. If the staff observes that the current conveyor belt 82 is full, they can switch to another idle conveyor belt 82 to temporarily store the package through the control button of the control cabinet 11 to ensure continuous operation at the input end.

[0028] After the sorting cart 2 receives the package, the control cabinet 11 instructs the translation component 4 and the lifting component 3 to work together to accurately move the sorting cart 2 to the target turnover box outside the sorting outlet 5. The sorting cart 2 delivers the package into the target turnover box, completing a single sorting operation, and then returns to the initial position to wait for receiving new packages, thus realizing continuous sorting operations. On the way back to the initial receiving position, the photoelectric detection device 9 scans the turnover boxes it passes in real time, detects and records the loading status of each turnover box, and the information is synchronously fed back to the control cabinet.

[0029] If the second conveyor belt 82 of the temporary storage component 8 is fully loaded, or after the full-box turnover box has been replaced, the control cabinet 11 instructs the sorting car 2 to move to the second conveyor belt 82 of the temporary storage, to receive the temporarily stored packages, and to re-sort them according to the target turnover box information.
