[0011] In one embodiment, the lifting mechanism includes a first lifting component and a second lifting component. Both the first lifting component and the second lifting component are connected to the frame. The first lifting component is located near the discharge end of the second conveying component, and the second lifting component is located on the side of the first lifting component away from the second conveying component.

[0019] In one embodiment, the first transfer platform further includes a second lifting member, and the second support plate includes a third end and a fourth end disposed opposite to each other along the extension direction of the second conveyor.

[0027] And / or,

[0031] And / or,

[0032] The second actuation mechanism includes a second rodless cylinder.

[0033] In this embodiment of the utility model, the material is a cargo box. A cargo box containing a water tank is a full box; a cargo box without a water tank is an empty box. The frame includes a first support and a second support, which are connected to each other in the left-right direction to form a stable frame, providing an installation foundation for the remaining components and ensuring a reasonable spatial layout and stable operation among the components. The conveying mechanism consists of four inclined conveying components in upper and lower layers. All four conveying components extend in the front-back direction. The first conveying component is located below the fourth conveying component, and the second conveying component is located below the third conveying component. The first pushing mechanism is connected to the first support, and the second pushing mechanism... The structure is connected to the second support, and the discharge and infeed ends of the first, second, third, and fourth conveying components form a continuous path, creating a continuous gravity sliding path. Without additional power, the cargo box can slide from a high position to a low position using its own gravity. Combined with the first pushing mechanism, lifting mechanism, and second pushing mechanism, precise transfer of the cargo box between different conveying components is achieved. This water tank empty-full exchange rack device replaces the original task of AGVs frequently shuttling between areas, reducing AGV scheduling pressure and path conflicts, and avoiding the problem of production line closure due to AGV operation, thereby ensuring... This avoids disrupting the continuity and safety of workshop production. However, through an efficient cargo box turnover mechanism, the overall cycle from inspection to production of water tanks is shortened, reducing inventory backlog, improving warehouse space utilization, and contributing to the construction of a lean logistics system. In this embodiment, the unloading port of the logistics vehicle and the feeding end of the first conveying component form a continuous path, allowing the full boxes on the logistics vehicle to enter the empty-full exchange rack device from the feeding end of the first conveying component. The full boxes slide along the first conveying component under their own weight to the discharging end of the first conveying component, and then the first pushing mechanism pushes the full boxes to the feeding end of the second conveying component. The conveyor component slides under its own weight from the discharge end of the second conveyor component to the lifting mechanism. At this point, the worker can take the water tank from the cargo box for subsequent assembly, and the cargo box becomes an empty box. The lifting mechanism drives the empty box to move vertically to the feed end of the third conveyor component. The empty box slides under its own weight on the third conveyor component to the discharge end of the third conveyor component. Then, the second pushing mechanism pushes the empty box to the feed end of the fourth conveyor component. The empty box slides under its own weight on the fourth conveyor component to the discharge end of the fourth conveyor component. Finally, the empty box is collected by the recycling port of the logistics vehicle, thus forming an automatic exchange of full and empty cargo boxes.This utility model embodiment employs four inclined conveying components to form a continuous cargo box flow path. Without additional power, the cargo boxes slide from high to low using their own gravity, reducing energy consumption and equipment wear, improving the stability and reliability of the conveying process, and avoiding the waiting and congestion problems caused by frequent transfers of traditional AGVs. This effectively simplifies the conveying process and improves work efficiency. Furthermore, the four conveying components have a compact and hierarchical layout, facilitating flexible adjustment or expansion according to actual production line needs. The use of a first and second pushing mechanism enables precise transfer of cargo boxes between different levels, reducing manual intervention and improving automation. The use of a lifting mechanism achieves automated exchange of full and empty boxes. The lifting mechanism not only receives and processes full boxes but also delivers processed empty boxes to downstream processes, ensuring that empty boxes can be promptly returned to the logistics system for continued use. This automated empty box return mechanism effectively solves the empty box management problem, ensuring the stability and continuity of the production rhythm. Attached Figure Description

[0041] 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 scope of protection of the present utility model.

[0042] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, and back), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0043] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] As modern manufacturing moves towards automation and intelligence, the efficiency and flexibility of logistics systems have become crucial for improving overall production efficiency. In particular, in the assembly process involving large, heavy-duty containers such as water tanks, the traditional manual handling method combined with AGVs has revealed problems of complex processes and low operational efficiency, which seriously restricts the overall operating efficiency and capacity improvement of the workshop.

[0045] After careful research, the applicant found that the current common empty-to-full water tank exchange production line is usually divided into three main areas: distribution area, repackaging area and assembly line area. The transportation between each area is completed by two AGVs. The first AGV is responsible for transporting the inspected and qualified water tanks from the distribution area to the repackaging area, and the second AGV transports the repackaged water tanks to the assembly line area near the assembly line for workers to pick up. Numerous problems arose during the entire operation. The water tanks required four equipment or manual handovers during their transfer (including receiving, transferring, sorting, and putting them online), making the operation complex and the entire cycle lasting 204 minutes. The connections between each link were not tight, resulting in low efficiency. Furthermore, the entire production line relied on only two AGVs to handle all transportation tasks, leading to high AGV scheduling pressure, frequent path intersections, and potential traffic bottlenecks. The two AGVs also experienced waiting and yielding issues when operating in tandem, further extending the transportation time. Moreover, to ensure safety, the relevant production line areas had to be closed off when the AGVs moved, affecting the overall production continuity. Due to the lack of an effective intermediate buffer mechanism, the water tanks had to remain in the transition area for extended periods, resulting in a large storage space occupation. The number of tanks in stock reached as high as 90, leading to severe inventory backlog, low space utilization, and increased management difficulty.

[0046] The main purpose of this utility model is to propose a water tank empty-full exchange rack device to solve the problem of how to simplify the handling process and improve work efficiency.

[0047] Please see Figure 1 and Figure 2In one embodiment of this utility model, the water tank empty-full exchange rack device 100 includes a frame 1, a conveying mechanism 2, a first pushing mechanism 3, a second pushing mechanism 4, and a lifting mechanism 5. The conveying mechanism 2 includes a first conveying component 21 and a second conveying component 22 arranged vertically on the frame 1. The first conveying component 21 includes a first conveying part 211, a second conveying part 212, and a first transfer platform 213. The discharge end of the first conveying part 211 and the inlet end of the second conveying part 212 are both connected to the first transfer platform 213. The inlet end of the first conveying part 211 is higher than the first transfer platform 213, and the discharge end of the second conveying part 212 is lower than the first transfer platform 213. The second conveying component 22 includes a third conveying part 221, a fourth conveying part 222, and a second transfer platform 223. The discharge end of the third conveying part 221 and the fourth conveying part 212 are connected to the first transfer platform 213. The feeding ends of all 22 are connected to the second transfer platform 223. The feeding end of the third conveying component 221 is higher than the second transfer platform 223, and the discharging end of the fourth conveying component 222 is lower than the second transfer platform 223. The discharging end of the second conveying component 212 is lower than the feeding end of the third conveying component 221. The first pushing mechanism 3 is connected to the frame 1 and is used to move the material 200 from the first conveying component 211 to the first transfer platform 213 to the feeding end of the second conveying component 212. The second pushing mechanism 4 is connected to the frame 1 and is used to move the material 200 from the third conveying component 221 to the second transfer platform 223 to the feeding end of the fourth conveying component 222. The lifting mechanism 5 is connected to the frame 1 and is used to move the material 200 from the discharging end of the second conveying component 212 to the feeding end of the third conveying component 221.

[0048] In this embodiment of the utility model, material 200 is a cargo box. A cargo box containing a water tank is a full box; a cargo box without a water tank is an empty box. The frame 1 includes a first support 11 and a second support 12, which are connected to each other in the left-right direction to form a stable frame, providing an installation foundation for the remaining components and ensuring a reasonable spatial layout and stable operation between the components. The conveying mechanism 2 consists of four inclined conveying components in the upper and lower layers. All four conveying components extend in the front-back direction. The first conveying component 211 is located below the fourth conveying component 222, and the second conveying component 212 is located below the third conveying component 221. The first pushing mechanism 3 is connected to the first support 11, and the second pushing mechanism 3 is connected to the first support 11. The actuator 4 is connected to the second support 12, and the discharge and infeed ends of the first conveying component 211, the second conveying component 212, the third conveying component 221, and the fourth conveying component 222 form a continuous path, creating a continuous gravity sliding path. Without additional power, the cargo box can slide from a high position to a low position using its own gravity. Combined with the first pushing mechanism 3, the lifting mechanism 5, and the second pushing mechanism 4, precise transfer of the cargo box between different conveying components is achieved. This water tank empty-full exchange rack device 100 replaces the original task of AGVs frequently shuttling between areas, reducing AGV scheduling pressure and path conflicts, and avoiding the problem of production line closure due to AGV operation, thereby ensuring... This avoids disrupting the continuity and safety of workshop production. However, through an efficient cargo box turnover mechanism, the overall cycle from inspection to production of water tanks is shortened, reducing inventory backlog, improving warehouse space utilization, and contributing to the construction of a lean logistics system. In this embodiment, the discharge port of the logistics vehicle and the infeed end of the first conveying component 211 form a continuous path, allowing the full boxes on the logistics vehicle to enter the empty-full exchange rack device 100 from the infeed end of the first conveying component 211. The full boxes slide along the first conveying component 211 under their own weight to the discharge end of the first conveying component 211. Then, the first pushing mechanism 3 pushes the full boxes to the infeed end of the second conveying component 22. The full boxes then slide along the second conveying component... The container 212 slides to the lifting mechanism 5 via the discharge end of the second conveying component 212 under its own weight. At this time, the worker can take the water tank in the container for subsequent assembly, and the container becomes empty. The lifting mechanism 5 drives the empty container to move vertically to the feed end of the third conveying component 221. The empty container slides to the discharge end of the third conveying component 221 under its own weight. Then, the second pushing mechanism 4 pushes the empty container to the feed end of the fourth conveying component 222. The empty container slides to the discharge end of the fourth conveying component 222 under its own weight. Finally, the empty container is collected by the recycling port of the logistics vehicle, thus forming an automatic exchange of the full and empty containers.

[0049] This invention employs four inclined conveying components to form a continuous cargo box flow path. Without additional power, the cargo boxes slide from high to low using their own gravity, reducing energy consumption and equipment wear, improving the stability and reliability of the conveying process, and avoiding the waiting and congestion problems caused by frequent transfers in traditional AGVs. This effectively simplifies the conveying process and improves work efficiency. Furthermore, the four conveying components have a compact and hierarchical layout, facilitating flexible adjustment or expansion according to actual production line needs. The use of a first pushing mechanism 3 and a second pushing mechanism 4 enables precise transfer of cargo boxes between different levels, reducing manual intervention and improving automation. The use of a lifting mechanism 5 achieves automated exchange of full and empty boxes. The lifting mechanism 5 not only receives and processes full boxes but also delivers processed empty boxes to downstream processes, ensuring that empty boxes can be promptly returned to the logistics system for continued use. This automated empty box return mechanism effectively solves the empty box management problem, ensuring the stability and continuity of the production rhythm.

[0050] Please see Figure 1 In one embodiment, the lifting mechanism 5 includes a first lifting component 51 and a second lifting component 52. Both the first lifting component 51 and the second lifting component 52 are connected to the frame 1. The first lifting component 51 is located near the discharge end of the second conveying component 212, and the second lifting component 52 is located on the side of the first lifting component 51 away from the second conveying component 212. The first lifting component 51 is used to restrict or allow the material 200 to move from the discharge end of the second conveying component 212 to the second lifting component 52. The second lifting component 52 is used to move the material 200 to the feed end of the third conveying component 221. Specifically, the first lifting component 51 is responsible for initially receiving the cargo box and deciding whether to release it, which can effectively prevent multiple cargo boxes from piling up on the second lifting component 52 at the same time, avoiding logistics blockage or equipment jamming. In the event of a pause, the second lifting component 52 selectively moves the cargo box to the next stage or keeps it in a buffer state based on the overall production line rhythm or task requirements. Together, they form a multi-level buffer and path switching module, which improves the system's flexibility and responsiveness. When the rhythms of the preceding and following processes are inconsistent, the lifting mechanism 5 can be used as a temporary buffer area to avoid affecting the operation of the entire production line due to the stagnation of a certain process, thereby improving system stability. The up-and-down movement of the two lifting components and the cargo box transfer process can be automatically completed by the control system without manual intervention, reducing labor intensity, simplifying the handling process, and improving work efficiency. In this embodiment, the lifting mechanism 5 not only supports forward cargo box flow but also reverse return operation, reserving interfaces and possibilities for building more complex intelligent logistics networks in the future.

[0051] Please see Figure 1In one embodiment, the first lifting assembly 51 includes a first driving member 511 and a first tray 512. The first tray 512 is used to carry material 200. The end of the first tray 512 near the second conveying member 212 is higher than the end of the first tray 512 near the second lifting assembly 52, so that the material 200 can move from the first tray 512 to the second lifting assembly 52 under the action of gravity. The first driving member 511 is connected to the frame 1 and is drively connected to the first tray 512. The first driving member 511 can drive the first tray 512 to lift. A pallet 512 has an ascending position 5121 and a descending position (not shown). A first drive member 511 can drive the first pallet 512 to reciprocate between the ascending position 5121 and the descending position. When the first pallet 512 is in the descending position, material 200 can move from the discharge end of the second conveying member 212 to the first pallet 512. When the first pallet 512 is in the ascending position 5121, material 200 on the first pallet 512 can move to the second lifting assembly 52, and the first pallet 512 can communicate with material 200 located at the discharge end of the second conveying member 212. The first pallet 512 serves to prevent material 200 from sliding out of the discharge end of the second conveying component 212. Specifically, the first pallet 512 has the function of receiving and transferring. When the first pallet 512 is in the descending position, it forms a continuous path with the discharge end of the second conveying component 212, receiving the cargo box sliding out from there. At this time, the first pallet 512 acts as the first buffer node in the cargo box flow process, preventing the cargo box from directly entering the next stage and causing congestion. When the first pallet 512 rises to the rising position 5121, it forms a continuous path with the second lifting component 52, transferring the carried cargo box to the second lifting component 212. The descending component 52, with its mechanism of receiving first and then transferring, enables orderly control of the cargo box flow. When the first pallet 512 is in the rising position 5121, it can also contact the cargo box located at the discharge end of the second conveying component 212, forming a physical barrier to prevent new cargo boxes from sliding out at this time. This allows the system to actively prevent the cargo boxes from continuing to move forward when it is necessary to pause the flow of cargo boxes (such as when downstream is full or malfunctions), avoiding the problem of logistics accumulation or blockage caused by multiple cargo boxes sliding in at the same time. It can also effectively prevent logistics disorder caused by downstream processes not being ready, thus improving the stability and fault tolerance of the system.

[0052] Please see Figure 1In one embodiment, the second lifting assembly 52 includes a second driving member 521 and a second pallet 522. The second pallet 522 is used to carry material 200. The second driving member 521 is connected to the frame 1 and is drively connected to the second pallet 522. The second driving member 521 can drive the second pallet 522 to lift, so that the second pallet 522 can receive material 200 leaving the first pallet 512 and can move the material 200 to the feeding end of the third conveying component 221. Specifically, the second lifting assembly 52, as a key node connecting the first lifting assembly 51 and the third conveying component 221, can realize the accurate receiving and orderly release of the cargo box, improving the cargo box turnover efficiency of the entire racking device. The second pallet 522 can selectively form a continuous connection with the first pallet 512 or the third conveying component 221 by moving up and down. The path allows for more flexible and controllable cargo flow, suitable for various production rhythms and process requirements. The second pallet 522 can move downward relative to the second support 12 to form a continuous path with the first pallet 512, receiving cargo boxes sliding out from the first pallet 512. It can also move upward relative to the second support 12 to form a continuous path with the feeding end of the third conveying component 221, sending the cargo boxes into the next level of conveying path. This receiving, buffering, and releasing mechanism enables efficient flow of cargo boxes between different levels. Moreover, when the rhythms of upstream and downstream processes are inconsistent, the second pallet 522 can be used as an intermediate buffer node to alleviate the logistics pressure caused by the speed difference between upstream and downstream processes and improve the stability of the entire line. The second lifting component 52 not only supports forward cargo box flow but can also cooperate with other modules to achieve reverse return operation, reserving interfaces and possibilities for building more complex intelligent logistics networks in the future.

[0053] In this embodiment, both the first driving component 511 and the second driving component 521 can be rodless cylinders, electric push rods, linear motors or hydraulic cylinders, so that the up and down movement of the first lifting mechanism 5 and the second lifting mechanism 5 and the cargo box transfer process can be automatically completed by the control system without manual intervention, reducing labor intensity, simplifying the handling process and improving work efficiency.

[0054] Please see Figure 1In one embodiment, the second tray 522 includes a mounting frame 5221, a tray body 5222, and a first lifting member 5223. The second driving member 521 is pulsatorically connected to the mounting frame 5221, and the tray body 5222 is rotatably connected to the mounting frame 5221. The tray body 5222 includes a first end 52221 and a second end 52222 disposed opposite to each other along the extending direction of the third conveying member 221. The first lifting member 5223 can drive the second end 52222 to rise, so that the second end 52222 is higher than the first end 52221, and the material 200 can move from the first end 52221 to the feeding end of the third conveying member 221. The first lifting member 5223 can also drive the second end 52222 to fall, so that the second end 52222 and the first end 52221 are at the same height. Specifically, by providing the first lifting member 5223, the tray body 5222 can freely switch between a horizontal state and an inclined state. This design allows the cargo box flow path to be flexibly adjusted according to system instructions, enhancing the system's automation and responsiveness. When the first lifting component 5223 lowers the second end 52222, the pallet body 5222 is in a horizontal state, and the first end 52221 forms a continuous path with the first pallet 512, receiving the cargo box that slides out from the first pallet 512. When the first lifting component 5223 raises the second end 52222, the pallet body 5222 tilts, causing the cargo box to slide towards the first end 52221, thereby realizing the transfer of the cargo box from the second pallet 522 to the third conveying component 221. By changing the angle of the pallet body 5222, gravity is used to achieve automatic sliding and release of the cargo box, eliminating the need for an additional pushing mechanism, saving energy and reducing consumption, while simplifying the mechanical structure. Furthermore, the automated tilting and release mechanism can improve the efficiency of cargo box handover, reduce manual intervention and waiting time, help shorten the overall logistics cycle, and improve work efficiency.

The lifting mechanism 5 is used to move the material 200 from the discharge end of the second conveyor 2121 to the feed end of the third conveyor 2211. Specifically, all four conveyors are used to carry and guide the sliding of the cargo box. The four support plates, the feed plate 2112, and the discharge plate 2222 are used to assist the cargo box in smoothly entering or leaving the corresponding conveyor. By precisely controlling the height difference of the four conveyors, the cargo box can slide by its own gravity without the need for an additional drive device, which is energy-saving, environmentally friendly, and reduces mechanical wear. The first support plate 2131 and the second support plate 2132 can abut against each other to form the lower cargo box flow path. The first pushing mechanism 3 can push the cargo box from the first support plate 2131 to the second support plate 2132. The third support plate 2231 and the fourth support plate 2232 can abut against each other to form an upper cargo box flow path. The second pushing mechanism 4 can push the cargo box from the third support plate 2231 to the fourth support plate 2232, replacing manual handling and improving work efficiency and safety. The lifting mechanism 5 is used to move the material 200 from the discharge end of the second conveying component 212 to the feed end of the third conveying component 221, realizing bidirectional buffer scheduling and improving the stability and continuity of system operation. Through the efficient cargo box flow mechanism, the overall cycle from inspection to online operation of the water tank is shortened, inventory backlog is reduced, and the utilization rate of storage space is improved.

[0056] Please see Figure 1In one embodiment, the first transfer platform 213 further includes a second lifting member 2133, and the second support plate 2132 includes a third end 21321 and a fourth end 21322 disposed opposite to each other along the extension direction of the second conveyor 2121. The second lifting member 2133 can drive the fourth end 21322 to rise, so that the fourth end 21322 is higher than the third end 21321, and the material 200 can move from the third end 21321 to the feeding end of the second conveyor 2121. The second lifting member 2133 can also drive the fourth end 21322 to fall, so that the fourth end 21322 is at the same height as the third end 21321. And / or, the second transfer platform 223 further includes a third lifting member (not shown in the figure), and the fourth support plate 2232 includes a fifth end 22321 and a sixth end 22322 disposed opposite to each other along the extension direction of the fourth conveyor 2221. The third lifting member can drive the sixth end 22322 to rise, so that the sixth end 22322 is higher than the third end 21321. Above the fifth end 22321, material 200 can move from the fifth end 22321 to the feeding end of the fourth conveyor 2221; the third lifting member can drive the sixth end 22322 to descend so that the sixth end 22322 and the fifth end 22321 are at the same height; specifically, by setting the second lifting member 2133 and the third lifting member, the second support plate 2132 and the fourth support plate 2232 can freely switch between horizontal and inclined states. This design allows the cargo box flow path to be flexibly adjusted according to system instructions, enhancing the automation level and responsiveness of the system. By changing the angle of the second support plate 2132 and the fourth support plate 2232, gravity is used to achieve automatic sliding release of the cargo box without the need for an additional pushing mechanism, saving energy and reducing consumption. At the same time, it simplifies the mechanical structure, and the automated tilting release mechanism can also improve the efficiency of cargo box handover, reduce manual intervention and waiting time, help shorten the overall logistics cycle, and improve work efficiency.

[0057] Please see Figure 1In one embodiment, a plurality of first universal balls 21311 are spaced apart on the first support plate 2131; and / or, a plurality of second universal balls 21323 are spaced apart on the second support plate 2132; and / or, a plurality of third universal balls 22311 are spaced apart on the third support plate 2231; and / or, a plurality of fourth universal balls 22323 are spaced apart on the fourth support plate 2232. Specifically, when the cargo box moves on the support plate, traditional planar contact will generate a large frictional force. By setting universal balls on the support plate, the universal balls can transform the sliding friction into a more efficient and efficient frictional force. Replacing it with rolling friction greatly reduces sliding resistance and decreases the sticking phenomenon between the cargo box and the support plate, making the cargo box easier to move smoothly under the action of gravity or the pushing mechanism. This ensures that the cargo box can be accurately pushed onto the next conveyor. The omnidirectional ball bears the main friction load, which can reduce wear on the support plate, extend the equipment life, and reduce daily maintenance costs. The omnidirectional ball is usually made of metal or engineering plastic and is embedded in the corresponding support plate surface. It can roll freely. The distribution density of the omnidirectional ball is reasonably arranged according to the weight, size and sliding direction of the cargo box. This embodiment does not limit this.

[0058] In this embodiment, both the feed plate 2112 and the discharge plate 2222 are equipped with omnidirectional balls to reduce the sliding resistance of the cargo box and make the cargo box move more smoothly.

[0059] Please see Figure 1 In one embodiment, the water tank empty-full exchange rack device 100 further includes a control box 6 connected to the frame 1. The control box 6 includes a box body 61 and a start button 62, a stop button 63, and an empty box recycling button 64 disposed on the box body 61. The first pushing mechanism 3, the second pushing mechanism 4, and the lifting mechanism 5 are all electrically connected to the box body 61. Specifically, the box body 61 is the core control unit of the water tank empty-full exchange rack device 100, which centrally controls the first pushing mechanism 3, the second pushing mechanism 4, and the lifting mechanism 5, enabling fully automated control and reducing manual intervention. The start button 62 is used to start the entire operation process of the water tank empty-full exchange rack device 100. The stop button 63 is used to stop the system operation in an emergency or normal state. The empty box recycling button 64 is used to trigger the empty box recycling process, sending the used empty boxes back to the recycling port of the logistics vehicle. These buttons provide an intuitive human-machine interface, making it convenient for on-site operators to start and stop control or intervene in the process according to the actual situation, thereby improving on-site operation efficiency.

[0060] In this embodiment, the first lifting member 5223, the second lifting member 2133 and the third lifting member can all be electrically connected to the electrical box body 61, thereby realizing automated control.

[0061] Please see Figure 1In one embodiment, the first pushing mechanism 3 includes a first rodless cylinder; and / or, the second pushing mechanism 4 includes a second rodless cylinder. Specifically, the rodless cylinder can provide stable thrust and stroke control, ensuring that the cargo box is accurately pushed to the designated position, reducing manual intervention, improving the level of automation, and is quick to operate and flexible to reset. It can match the needs of high-paced production, shorten the cargo box turnover cycle, and the rodless cylinder does not need to extend the piston rod, making the layout more compact and easy to embed in the first bracket 11 or the second bracket 12. It is suitable for space-constrained application scenarios. The rodless cylinder has a simple structure, good sealing performance, requires less daily maintenance, and has strong durability, which helps to reduce operation and maintenance costs. Different specifications of rodless cylinders can also be selected according to different load requirements to enhance system scalability.

[0062] In this embodiment, the first pushing mechanism 3 and the second pushing mechanism 4 may also be electric push rods, linear motors or hydraulic cylinders, so that the first pushing mechanism 3 and the second pushing mechanism 4 can push the cargo box to transfer without manual intervention, reducing labor intensity, simplifying the handling process and improving work efficiency.

[0063] Please see Figure 2 In one embodiment, the first conveyor 2111, the second conveyor 2121, the third conveyor 2211, and the fourth conveyor 2221 can all be fluid flow strips. The fluid flow strips replace sliding friction with rolling friction, allowing the cargo box to slide down the inclined surface more easily, reducing power requirements and improving the overall system efficiency. The design of the fluid flow strips ensures that the cargo box will not get stuck or blocked during the sliding process, guaranteeing the continuous and stable flow of the cargo box. This is especially suitable for automated production lines. By adjusting the inclination angle of the fluid flow strips, the sliding speed of the cargo box can be flexibly controlled to adapt to different production rhythms and process requirements, enhancing the flexibility of the system. Moreover, the fluid flow strips have a simple structure, are easy to disassemble and clean, and are convenient for daily maintenance. If damage occurs, only individual balls or rollers need to be replaced, resulting in low maintenance costs and extending the service life of the equipment. The number and spacing of the fluid flow strips in each conveyor can be reasonably arranged according to the size and weight of the cargo box to ensure that each cargo box is fully supported. This embodiment does not limit this.
