Description

Technical Field

[0001] This invention belongs to the technical field of packaging system, and more specifically, it relates to an automatic centralized packaging system for express logistics sorting. Background Technology

[0002] In the sorting operations of the express delivery and logistics industry, automated sorting equipment such as cross-belt sorters and tilting sorters have been widely used, achieving high-efficiency automation in the mail sorting process. However, the current post-sorting collection process still relies on traditional manual operation: the sorting equipment's compartments are arranged in a linear array, and the collection containers are woven bags. The woven bags need to be manually placed under the compartments, and after the mail is full, the bags are manually unpacked, transported away, and repacked with new woven bags.

[0003] Traditional manual sorting requires a large workforce, with a ratio of sorting staff to sorting slots of approximately 1:15. Typically, 300 sorting slots require around 20 people, making it the most labor-intensive part of the sorting process. At the same time, it suffers from low efficiency, with significant differences in mail volume along different routes, resulting in uneven workloads for sorting staff and failing to fully utilize their human resources. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an automated collection and centralized packaging system for express logistics sorting, thereby solving the technical problem of high manual labor input in the traditional manual collection mode in the prior art.

[0005] The purpose and effectiveness of the automatic collection and centralized packaging system for express logistics sorting of the present invention are achieved by the following specific technical means: An automated collection and centralized package-building system for express logistics sorting includes: The main ring of the sorting machine is used to carry and transport mail, sorting the mail to the corresponding output position according to the preset route. Multiple receiving compartments are located on both sides of the main ring of the sorting machine and are evenly distributed along the circumference of the main ring of the sorting machine to receive mail falling from the main ring of the sorting machine. Multiple buffer positions are located on the side of the receiving grid near the main ring of the sorting machine, used to pre-store spare empty turnover boxes, providing instant box replenishment support for the receiving grid; An empty box line, one end of which is located below the main ring of the sorting machine, is used to provide empty turnover boxes for the buffer position; The full box line is located on the side of the empty box line away from the main ring of the sorting machine; The manual station is located on the side of the full box line away from the main ring of the sorting machine. It has a flipping mechanism for emptying the mail from the box so that manual staff can complete the packaging and sealing operations.

[0006] In a preferred embodiment, it further includes: Empty container mobile transfer is distributed in the area between the empty container line and the buffer position, and is used to transfer the empty turnover box of the empty container line to the empty buffer position when the buffer position detects a vacancy; Full-box mobile transfer, distributed in the area between the receiving compartment and the full-box line, is used to move full turnover boxes to the full-box line; The fixed transfer mechanism is used to transfer full-loaded turnover boxes conveyed by the full-load line to the flipping mechanism, and after the mail is dumped, to transfer empty turnover boxes from the manual station to the empty box line. The control module is electrically connected to the sorting machine main ring, the receiving grid, the buffer grid, the empty box line, the full box line, the empty box mobile transfer, the full box mobile transfer, the manual station, and the fixed transfer.

[0007] In a preferred embodiment, the receiving compartment is equipped with a photoelectric detection device for detecting the full state of the turnover box, and is electrically connected to the control module.

[0008] The control module is electrically connected to the photoelectric detection device and the proximity switch, respectively.

[0009] In a preferred embodiment, the buffer position is provided with a proximity switch for detecting the presence of an empty turnover box; It is also electrically connected to the control module.

[0010] In a preferred embodiment, the empty container mobile transfer and the full container mobile transfer are both jacking transfer machines.

[0011] In a preferred embodiment, the fixed transfer is a belt conveyor or roller conveyor line, which is set on the empty box line and the full box line.

[0012] In a preferred embodiment, multiple sets of receiving slots and multiple sets of buffer slots are arranged in a straight line along the side of the main ring of the sorting machine, and the number of buffer slots is equal to the number of receiving slots.

[0013] In a preferred embodiment, both the empty box line and the full box line are C-shaped, and the empty box line and the full box line are adjacent to each other at the section near the work position.

[0014] In a preferred embodiment, the flipping mechanism is a lifting flipping machine.

[0015] In a preferred embodiment, the control method of the control module includes the following steps: S1. Buffer replenishment: The control module receives the buffer slot vacancy signal and schedules the empty box mobile transfer to move the empty turnover box of the empty box line to the vacant buffer slot; S2, Mail Collection Grid: The main ring of the sorting machine sorts the mail into the collection grid turnover box. The photoelectric detector sends a signal after detecting that the box is full. S3. Synchronous container transfer: The full container is moved to the target receiving compartment, and the full container is transferred to the full container line and the empty container is put into the receiving compartment simultaneously. S4. Centralized Packaging: The full box line transports the full box to the manual station, and the fixed transfer mechanism transfers it to the flipping mechanism. The unloaded mail is then available for manual packaging. S5. Empty Box Return: The fixed transfer system moves empty turnover boxes to the empty box line and transports them to the buffer area to wait for replenishment, thus realizing a cycle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the coordinated setup of receiving compartments, buffer compartments, and mobile transfer mechanisms, combined with the layout of C-shaped empty and full container lines, achieves a revolutionary "goods-find-person" operation mode, significantly reducing manual labor input. The manual operation mode shifts from decentralized and mobile to centralized and fixed, eliminating the need for back-and-forth travel. Simultaneously, the control module, through "peak shaving and valley filling" scheduling, balances the mail flow at each manual position, resolving the problem of uneven workload caused by differences in mail volume along different routes, and fully improving personnel operational efficiency.

[0017] 2. When using this device, the continuous operation of the lifting and transfer machine enables the simultaneous transfer of full boxes and replenishment of empty boxes, ensuring uninterrupted mail reception at the receiving stations and meeting the operational requirements of high-speed sorting machines. The centralized arrangement of manual workstations facilitates the standardized placement of fire exits, safety railings, and comfort facilities, improving operational safety and convenience. The automatic tilting mechanism by the lifting and tipping machine reduces manual handling intensity, and combined with the fixed transfer system, achieves closed-loop return of empty boxes, forming a fully automated "receiving-transfer-packing-return" process. This significantly improves the overall efficiency and stability of sorting and receiving, while also being compatible with various types of small-item sorting machines, making it suitable for a wide range of applications.

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0021] Example

[0022] like Figures 1 to 3 As shown, this invention provides an automated sorting and centralized packaging system for express logistics, comprising: a sorting machine main ring 101 for carrying and transporting mail, sorting the mail to corresponding output positions according to a preset route; multiple sets of receiving slots 102 located on both sides of the sorting machine main ring 101, evenly distributed around the circumference of the sorting machine main ring 101, for receiving mail falling from the sorting machine main ring 101; and multiple sets of buffer slots 103 located on the side of the receiving slots 102 closest to the sorting machine main ring 101. The empty box line 105 is used to pre-store spare empty turnover boxes to provide immediate box replenishment support for receiving position 102; one end of the empty box line 105 is located below the main ring 101 of the sorting machine and is used to provide empty turnover boxes for buffer position 103; the full box line 106 is set on the side of the empty box line 105 away from the main ring 101 of the sorting machine; the manual position 107 is set on the side of the full box line 106 away from the main ring 101 of the sorting machine, and it has a flipping mechanism 108 for emptying the mail in the box for manual packaging and sealing operations.

[0023] Empty box moving transfer 109 is distributed in the area between the empty box line 105 and the buffer position 103, and is used to transfer the empty turnover box of the empty box line 105 to the empty buffer position 103 when the buffer position 103 detects an empty space; Full box moving transfer 111 is distributed in the area between the receiving position 102 and the full box line 106, and is used to move the full turnover box to the full box line 106; Fixed transfer 112 is used to transfer the full turnover box conveyed by the full box line 106 to the flipping mechanism 108, and after the mail is dumped, to transfer the empty turnover box from the manual position 107 to the empty box line 105.

[0024] Empty container mobile transfer 109 and full container mobile transfer 111 are lifting transfer machines.

[0025] The fixed transfer device 112 is a belt conveyor or roller conveyor line, which is installed on the empty box line 105 and the full box line 106.

[0026] Multiple sets of receiving slots 102 and multiple sets of buffer slots 103 are arranged in a straight line along the side of the main ring 101 of the sorting machine, and the number of buffer slots 103 is equal to the number of receiving slots 102.

[0027] Both the empty box line 105 and the full box line 106 are C-shaped, and the empty box line 105 and the full box line 106 are adjacent to each other near the work position 107.

[0028] The flipping mechanism 108 is a lifting flipping machine.

[0029] It is understandable that the sorting machine's main ring 101 is arranged in a horizontal straight line for dual-zone sorting. A cross-belt sorting machine (model: CBT-1200) can be used, with its operating direction from the input end to the output end. It is used to carry and transport mail, sorting the mail to the corresponding output positions on both sides according to the preset route.

[0030] Multiple collection slots 102 are evenly arranged along the length of both sides of the main ring 101 of the sorting machine. The spacing between two adjacent collection slots 102 is consistent. Each collection slot 102 is equipped with a turnover box. The turnover box is made of high-strength ABS plastic and is injection molded in one piece. The inside of the box is equipped with rubber anti-slip pads. The sides of the box are equipped with guide bosses that are compatible with the transfer mechanism of the transfer equipment, which are used to receive mail falling from the main ring 101 of the sorting machine.

[0031] It should be noted that an RFID positioning tag (not shown in the figure) can be installed inside the turnover box. The tag is embedded in a pre-set groove at the bottom of the box and sealed with sealant. It can work with the receiving compartment 102, the buffer compartment 103 and the readers (not shown in the figure) on each transfer device to realize the real-time location tracking and identification of the turnover box in the system. This ensures that the control module 104 schedules the transfer device to perform box replenishment and box replacement actions, and avoids the turnover box being misplaced or confused.

[0032] Multiple sets of receiving compartments 102 and buffer compartments 103 are arranged in a straight line with equal spacing along both sides of the main ring 101 of the sorting machine. The number of buffer compartments 103 is exactly equal to that of receiving compartments 102 and they are arranged one after another in close proximity. The buffer compartments 103 are set close to the side of the receiving compartments 102 that is near the main ring 101 of the sorting machine. Through structural adaptation, the spare empty turnover boxes are stably pre-stored, providing instant box replenishment support for the receiving compartments 102 and ensuring uninterrupted receiving operations.

[0033] Both the empty box line 105 and the full box line 106 adopt a C-shaped layout. One end of the empty box line 105 extends to the area below the main ring 101 of the sorting machine, forming an empty turnover box supply channel. The full box line 106 is arranged parallel to the side of the empty box line 105 away from the main ring 101 of the sorting machine, forming an independent full box transfer path. The sections of both near the manual station 107 are arranged adjacent to each other and in parallel, forming an intensive transfer operation unit. By optimizing the path, the turnover box transfer journey is shortened, and the system's logistics efficiency is improved.

[0034] Both the empty container mobile transfer 109 and the full container mobile transfer 111 adopt lifting transfer machines, which cover the working areas between the empty container line 105 and the buffer position 103, and the receiving position 102 and the full container line 106 in a distributed layout. Through the integrated and continuous action of "lifting-transferring-lowering", the empty turnover boxes are replenished to the buffer position 103 and the full turnover boxes are smoothly transferred to the full container line 106, ensuring that the receiving position 102 is always in an effective working state.

[0035] The manual handling station 107 is centrally located on the side of the full box line 106 away from the main ring 101 of the sorting machine. Its integrated flipping mechanism 108 is a lifting and flipping machine. Through the mechanical transmission system, it realizes the automated and continuous action of "lifting-flipping-tipping-resetting" of the turnover box, providing a standardized and centralized operation interface for manual bagging and sealing. The fixed transfer 112 uses a belt conveyor or roller conveyor line and is deployed on the empty box line 105 and the full box line 106. As a key connecting unit of the closed-loop transfer of the system, it realizes the directional transfer of full turnover boxes to the flipping mechanism 108 and completes the return transport of empty turnover boxes to the empty box line 105 after the mail is dumped, thus constructing a fully automated operation link of "collection-transfer-bagging-return".

[0036] It also includes a control module 104, which is electrically connected to the sorting machine main ring 101, receiving station 102, buffer station 103, empty box line 105, full box line 106, empty box mobile transfer 109, full box mobile transfer 111, manual station 107 and fixed transfer 112 respectively.

[0037] The receiving compartment 102 is equipped with a photoelectric detection device for detecting the full status of the turnover box, and is electrically connected to the control module 104.

[0038] The control module 104 is electrically connected to the photoelectric detection device and the proximity switch, respectively.

[0039] The buffer position 103 is equipped with a proximity switch for detecting the presence of an empty turnover box; and is electrically connected to the control module 104.

[0040] It should be noted that the top inner side of the receiving compartment 102 has a pre-set standardized installation station for an embedded diffuse reflection photoelectric detection device (selection: E3Z-D61). Its detection direction is perpendicular to the inside of the turnover box. By analyzing the intensity changes of the emitted and received reflected light signals, it accurately quantifies and identifies the height of the mail stack inside the box. When the mail stack height reaches the preset full box threshold, the photoelectric detection device instantly generates a high-level full box signal, which is transmitted via a twisted-pair shielded cable (selection: RVVP2×0.75) to the digital signal input terminal of the microcontroller (selection: STM32F103), establishing a real-time feedback link for the full box status and ensuring the anti-interference and timeliness of signal transmission.

[0041] The bottom of buffer position 103 corresponds to the center reference position of the empty turnover box placement area. An inductive proximity switch (selection: TL-N10ME1) is fixedly installed there. Its detection surface is coaxially aligned with the metal sensing plate preset on the bottom of the turnover box, and the detection distance is adapted to the standard placement height of the empty turnover box. When an empty turnover box is placed in buffer position 103, the proximity switch is triggered by the metal sensing plate to generate a low-level presence signal. When an empty turnover box is placed in the storage compartment 102, the proximity switch loses its induction trigger and switches to generate a high-level absence signal. This signal is transmitted to the microcontroller via an industrial signal cable (selection: RVV2×0.5) to realize the determination of the empty turnover box's presence status.

[0042] It also includes a control module 104 (selected: STM32F103 microcontroller), which establishes stable electrical connections with the sorting machine main ring 101, receiving station 102, buffer station 103, empty box line 105, full box line 106, empty box mobile transfer 109, full box mobile transfer 111, manual station 107 and fixed transfer 112 through a dedicated I / O interface and serial communication bus, respectively, to build a collaborative control network for the entire system.

[0043] It should be noted that neither the photoelectric detection device nor the proximity switch is shown in the diagram, but they are conventional detection components in this technical field. Their installation layout, signal transmission method and adaptation logic all conform to the general technical specifications of logistics automation equipment. They are technical means that can be directly implemented by those skilled in the art based on conventional design ideas, and can achieve adaptation and stable operation with the control module 104 without additional creative labor.

[0044] like Figures 1 to 4 As shown, the control method of control module 104 includes the following steps: S1, buffer replenishment: control module 104 receives a vacancy signal from buffer position 103 and schedules empty box mobile transfer 109 to transfer empty turnover boxes from empty box line 105 to vacant buffer position 103; S2, mail collection: sorting machine main ring 101 sorts mail to collection position 102 turnover boxes, and the photoelectric detector sends a signal after detecting a full box; S3, synchronous box changing: full box mobile transfer 1... 11. Move to the target receiving compartment 102, simultaneously completing the transfer of full boxes to the full box line 106 and the replenishment of empty boxes into the receiving compartment 102; S4. Centralized packing: the full box line 106 transports the full boxes to the manual station 107, and the fixed transfer 112 transfers them to the flipping mechanism 108, after which the mail is dumped for manual packing; S5. Empty box return: the fixed transfer 112 transfers the empty turnover box to the empty box line 105, and transports it to the buffer area 103 to wait for replenishment, thus realizing the cycle.

[0045] Understandably, after being sorted by the main ring 101 of the sorting machine, the mail falls into the turnover box in the receiving compartment 102. The turnover box completes the transition from an empty state to a full state, and the full state is determined by the photoelectric detection device. The buffer position 103 is arranged adjacent to the upstream of the receiving compartment 102, pre-stores empty turnover boxes, and has a one-to-one configuration with the receiving compartment 102. When the photoelectric detection device triggers the full box signal, the control module 104 dispatches the nearest idle full box mobile transfer 111 to move it below the target receiving compartment 102. The full box mobile transfer 111 completes two core operations simultaneously through an integrated "lifting-transferring-lowering" action: first, transferring the full turnover box from the receiving compartment 102 to the full box line 106; second, replenishing the empty turnover box in the buffer position 103 into the receiving compartment 102, realizing seamless connection and continuous cycle of the receiving operation.

[0046] After fully loaded tote boxes enter the full-box line 106, they are transported in a queue along a preset conveyor path to the manual station 107 area. When a fully loaded tote box reaches the corresponding workstation in the manual station 107, the fixed transfer device 112 located below the full-box line 106 is activated, smoothly moving the tote box out of the full-box line 106 and transferring it to the flipping mechanism 108 in the manual station 107. The flipping mechanism 108 sequentially performs four automated actions: "lifting - flipping - tipping - resetting," converting the fully loaded tote box to an empty state. The tipped-out mail is then transported to a preset mailbag via a dedicated conveyor mechanism, and subsequent bagging and sealing processes are completed manually using standardized operations.

[0047] After being transferred to the empty box line 105 via the fixed transfer unit 112, the empty boxes are transported in a queue along the closed-loop conveyor path to the designated area between the two rows of buffer positions 103 in the receiving area. When an empty box in the buffer position 103 is replenished in the receiving position 102, a proximity switch detects the vacancy in the buffer position 103 and sends a signal. The control module 104 then dispatches the nearest available empty box mobile transfer unit 109 to move below the buffer position 103. A single empty box mobile transfer unit 109 can simultaneously cover two buffer positions 103 in the same column and the corresponding boxes on the empty box line 105. Through a continuous "lifting-transferring-lowering" action, the empty boxes on the empty box line 105 are transferred to the vacant buffer position 103, completing the empty box replenishment cycle.

[0048] The aforementioned three cycles of receiving and exchanging boxes, manual packaging, and buffer box replenishment work together to form a fully automated closed-loop operation mechanism for the entire system, encompassing "receiving boxes - transferring goods - packaging - returning goods".

[0049] For example, in the traditional sorting process of the express logistics industry, after mail is sorted and placed into slots by sorting machines, it is all handled manually. Typically, a sorting machine is equipped with more than 200 slots, with mailbags hanging under each slot for collecting mail. Each operator manages about 10-20 slots. Operators need to travel back and forth to the slot area they manage. When a slot is full, they then collect the mail and create new packages. The overall process is "person finds goods".

[0050] Using this application, in the same sorting scenario, each compartment is fitted with a turnover box instead of mailbags. After the mail falls into the turnover box and the compartment is full, the system moves the full box out of the compartment using "full box moving transfer 111" and simultaneously inserts an empty box into the compartment using "empty box moving transfer 109," achieving a fully automated sorting process. This automated process takes approximately 10 seconds from the triggering of the previous full box signal to the placement of the next replaced empty box, while the traditional sorting mode takes approximately 30 seconds for manual sealing and replacement of mailbags, thus improving the sorting efficiency of the sorting machine. After the full box is moved out of the compartment, it continues to be automatically transferred to the manual station 107. The transfer equipment can be conventional equipment such as roller conveyors or belt conveyors. After the full box enters the manual station 107, the mail inside is emptied and sent into mailbags through modules such as transfer, lifting and turning equipment, belt conveyors, and chutes. Subsequently, manual handling of subsequent steps such as mailbag sealing is performed. Under the new model, operators no longer need to move back and forth to their work locations, achieving "goods finding people".

[0051] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
