Description

Technical Field

[0001] This utility model relates to the technical field of express delivery sorting, and in particular to a double-layer staggered flip-type sorting machine and sorting and transport line. Background Technology

[0002] With the rapid development of e-commerce and modern logistics, logistics sorting systems are facing higher demands for processing efficiency, space utilization, and human-machine collaborative operation capabilities. Flip-type sorting machines, as a common type of automated sorting equipment, are widely used in express delivery, e-commerce warehousing, and other scenarios due to their simple structure, high sorting accuracy, and suitability for small and medium-sized parcels.

[0003] Traditional flip-type sorting machines typically employ a single-layer horizontal layout, where all flip-type units are linearly arranged on the same horizontal plane along the conveying direction. While this layout offers a clear structure and simple control logic, it suffers from a significant space utilization bottleneck: to meet high throughput demands, the equipment length often needs to be greatly increased, resulting in a large footprint and making it unsuitable for small spaces. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a double-layer staggered flip-type sorting machine and sorting and transport line, which solves the technical problems of low space utilization of traditional flip-type sorting machines in the prior art, which often require a significant increase in equipment length to meet high throughput requirements, resulting in a large footprint and difficulty in adapting to small sites.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] In the first aspect, this utility model provides a double-layer staggered flip-plate sorting machine, including a sorting unit and a connecting device;

[0009] The sorting unit consists of two vertically spaced units, each including a frame and a flip-up device connected to the frame.

[0010] The connecting device is suitable for connecting vertically adjacent frames and establishing a sliding connection relationship between vertically adjacent frames along the width direction of the sorting unit;

[0011] The double-layer staggered flip-board sorting machine can slide and switch between aligned and staggered packing states;

[0012] In the aligned state, the upper sorting unit can slide along its own width direction to a position where its vertical projection is in the same vertical plane as the lower sorting unit.

[0013] In the staggered loading state, the upper sorting unit can slide along its own width direction to a position that is staggered from the vertical projection position of the lower sorting unit in the vertical plane, so that a loading clearance area is formed above the lower flip device in the staggered loading state.

[0014] Secondly, this utility model provides a sorting and transport line, including a line body and multiple double-layer staggered flip-plate sorting machines as described in the above technical solution, with the lower sorting units connected end to end along the extension direction of the line body.

[0015] It also includes a misaligned guide rail, which corresponds to the height position of the upper sorting unit and is suitable for use with a guiding device to switch the corresponding double-layer misaligned flip-top sorter to a misaligned packing state or an aligned state.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this invention are as follows: Because the sorting machine adopts a vertical double-layer layout, it can save horizontal space and make better use of vertical space. Furthermore, since the sorting machine can switch between aligned and staggered packing states, the sorting units remain vertically stacked in the aligned state, and are vertically staggered in the staggered packing state to reserve a packing clearance area. Therefore, multi-layer arrangement will not affect the packing operation.

[0018] This double-layer staggered flip-top sorting machine achieves a dual improvement in space utilization efficiency and operational flexibility through its ingenious structural design.

[0019] The machine comprises two vertically spaced sorting units, each containing a frame and a flip-up device mounted thereon. Adjacent sorting units are slidably connected along the width direction via a connecting device. This connection method not only ensures the stability of each layer of the structure during operation but also gives the overall system the ability to flexibly switch between two working states: aligned state and misaligned packing state.

[0020] In the aligned state, except for the bottom sorting unit which remains fixed, the remaining sorting units slide along the width direction, causing their projections in a vertical plane to overlap, forming a compact stack. This layout minimizes the horizontal space occupied by the equipment, allowing the entire sorting system to extend vertically and effectively utilize the often underutilized vertical space in factory or warehouse environments. In the staggered loading state, where package loading or manual intervention is required, the upper sorting units slide offset along the width direction, preventing the vertical projections of the two vertical flip-board devices from overlapping, thus creating independent, unobstructed loading clearance areas above the lower flip-board devices. This staggered layout significantly improves the convenience of operators or automated loading equipment for each flip-board layer, ensuring loading efficiency.

[0021] This technical solution offers several advantages. First, the vertically stacked sorting units significantly reduce the floor space required for the equipment while multiplying the sorting capacity, making it particularly suitable for logistics sorting centers with limited space but sufficient ceiling height. Second, the switchable operation and loading modes ensure both a compact structure and coordinated movements during high-speed sorting, while providing ample operating space when manual intervention or replenishment is needed, balancing automation efficiency with the convenience of human-machine collaboration. Third, the flip-plate device boasts a simple structure and low cost, mitigating the increased costs associated with multi-layered sorting units.

[0022] The flip-plate device achieves a better balance between packing efficiency and energy consumption, thereby balancing costs.

[0023] Overall, this solution has improved spatial layout and enhanced operational adaptability while increasing sorting capacity. It also lays a solid structural foundation for the modular expansion of future high-density intelligent sorting systems, and is particularly suitable for small and medium-sized express delivery sub-stations with moderate parcel volume and limited space.

[0050] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-9 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is used as a reference.

[0051] Example 1:

[0052] Reference Figures 1-9This utility model provides a double-layer staggered flip-board sorting machine, characterized in that it includes sorting units 10 and connecting devices 20; the sorting units 10 are two vertically spaced units, each including a frame 102 and a flip-board device 104 connected to the frame 102; the connecting devices 20 are adapted to connect vertically adjacent frames 102 and establish a sliding connection relationship between vertically adjacent frames 102 along the width direction of the sorting units 10; the double-layer staggered flip-board sorting machine can slide between an aligned state and a staggered loading state; in the aligned state, the upper sorting unit 10 can slide along its own width direction to a position where its vertical projection is in the same vertical plane as the lower sorting unit 10; in the staggered loading state, the upper sorting unit 10 can slide along its own width direction to a position where its vertical projection is staggered from the lower sorting unit 10 in the vertical plane, so that a loading clearance area is formed above the lower flip-board device 104 in the staggered loading state.

[0053] Because the sorting machine adopts a vertical double-layer layout, it can save horizontal space and make better use of vertical space. Furthermore, since the sorting machine can switch between aligned and staggered packing states, the sorting units 10 remain vertically stacked in the aligned state, and are vertically staggered in the staggered packing state to reserve a packing clearance area. Therefore, the multi-layer layout will not affect the packing operation.

[0054] This double-layer staggered flip-top sorting machine achieves a dual improvement in space utilization efficiency and operational flexibility through its ingenious structural design.

[0055] The machine comprises two vertically spaced sorting units 10. Each sorting unit 10 includes a frame 102 and a flip-up device 104 mounted thereon. Adjacent sorting units 10 are slidably connected along the width direction via a connecting device 20. This connection method not only ensures the stability of each layer of the structure during operation, but also gives the overall system the ability to flexibly switch between two working states: aligned state and misaligned packing state.

[0056] In the aligned state, except for the bottom sorting unit 10 which remains fixed, the remaining sorting units 10 slide along the width direction, causing their projections in a vertical plane to overlap, forming a compact stack. This layout minimizes the horizontal space occupied by the equipment, allowing the entire sorting system to extend vertically and effectively utilize the often underutilized vertical space in factory or warehouse environments. In the staggered packing state, where package loading or manual intervention is required, the upper sorting units 10 slide offset along the width direction, so that the vertical projections of the two vertical flip-board devices 104 no longer overlap, thus creating independent, unobstructed packing clearance areas above the lower flip-board device 104. This staggered layout significantly improves the convenience of operators or automated packing equipment for each flip-board layer, ensuring packing efficiency.

[0057] Using this technical solution, firstly, the vertically stacked sorting unit 10 significantly reduces the floor space of the equipment and multiplies the sorting capacity, making it particularly suitable for logistics sorting centers with limited space but sufficient floor height; secondly, the switchable mechanism between operation and loading modes ensures a compact structure and coordinated movements during high-speed sorting, while providing ample operating space when manual intervention or replenishment is required, thus balancing automation efficiency with the convenience of human-machine collaboration; thirdly, the flip-plate device 104 has the advantages of simple structure and low cost, balancing the increased cost caused by the multi-layered sorting unit 10.

[0058] Overall, this solution has improved spatial layout and enhanced operational adaptability while increasing sorting capacity. It also lays a solid structural foundation for the modular expansion of future high-density intelligent sorting systems, and is particularly suitable for small and medium-sized express delivery sub-stations with moderate parcel volume and limited space.

[0059] It also includes the ability to handle packet loading in the current state.

[0060] A buffer for impact force between the pallet 1042 and the frame 102, the buffer being connected to the pallet 1042 and / or the frame 102. The buffer may include a spring and / or a damper; if it is a spring, it may be fitted onto a slide bar 1046 and located between the frame 102 and the pallet 1042.

[0061] In this embodiment, to further improve the stability of equipment operation and structural durability, the gravity-type flip-board sorting machine is also equipped with a buffer, which is specifically used to absorb and dissipate the impact energy generated by the rapid tilting between the pallet 1042 and the frame 102 when the package is being unloaded. By deforming and absorbing most of the impact kinetic energy, it effectively reduces the instantaneous impact force of the pallet 1042 hitting the frame 102 or the limiting structure, avoids the pallet 1042 hitting the frame 102, and also avoids the pallet 1042 vibrating frequently after descending, thus improving the stability of the gravity-type flip-board sorting machine when unloading packages.

[0062] Example 2:

[0063] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0064] The double-layer staggered flip-top sorting machine also includes a guide device 30, which is fixedly connected to the upper sorting unit 10. The guide device 30 drives the upper sorting unit 10 to slide, allowing the double-layer staggered flip-top sorting machine to enter either an aligned state or a staggered loading state. Furthermore, the guide device 30 may also have a locking function, locking the relative positions of the two sorting units 10 in both the aligned and staggered loading states.

[0065] In this embodiment, the guide device 30 is fixed to the upper sorting unit 10, which not only guides its sliding trajectory, but also has locking and unlocking functions. It can lock the position of the upper sorting unit 10 relative to the lower sorting unit 10 in the aligned state and the misaligned packing state, thereby ensuring the stability of the double-layer misaligned sorting machine when it is not in the misaligned sliding process, and improving the reliability of the double-layer misaligned sorting machine.

[0066] The guide device 30 includes a swing rod 302, a lever 304, and a locking pin 306. The lower frame 102 has a limiting hole 300, the position of which corresponds to the position of the locking pin 306 in the aligned state.

[0067] The middle part of the swing rod 302 is hinged to the upper frame 102 along the front and rear axis;

[0068] The lever 304 is fixedly connected to one end of the swing lever 302;

[0069] The locking pin 306 is slidably connected to the upper frame 102, and the other end of the swing rod 302 cooperates with the locking pin 306;

[0070] The guide device 30 can switch between a limited state and a disengaged state;

[0071] In the limited position state, the locking pin 306 is inserted into the corresponding limiting hole 300 of the lower frame 102;

[0072] In the disengaged state, the lever 304 drives the swing lever 302 to rotate by a first angle, so that the other end of the lever 304 drives the locking pin 306 to slide until the locking pin 306 disengages from the corresponding limiting hole 300.

[0073] In this embodiment, the guide device 30 achieves precise control and reliable locking of the relative position between the upper and lower frames 102 through the linkage of the swing rod 302, the lever 304, and the locking pin 306. Specifically, the middle part of the swing rod 302 is mounted on the upper frame 102 via a hinge shaft in the front-rear direction, forming a lever structure that can swing around the axis; one end is rigidly connected to the lever 304 to receive external driving or manual operation force; the other end is kinematically coupled to the locking pin 306 slidably disposed on the upper frame 102. The lower frame 102 is provided with a limiting hole 300 at a corresponding position, the position of which corresponds to the axial projection position of the locking pin 306 when the whole machine is in the aligned state.

[0074] When the machine needs to operate stably in an aligned state, the guide device 30 is in a limited position: at this time, the locking pin 306 falls under the action of gravity or elasticity and accurately inserts into the corresponding limiting hole 300 of the lower frame 102, rigidly locking the relative position of the upper and lower frames 102 in the width direction, effectively preventing accidental slippage caused by vibration, inertia or external force interference, thereby ensuring the accuracy and safety of the sorting process.

[0075] When a switch between working states is required, the operating lever 304 causes the swing lever 302 to rotate around the hinge axis by a first angle. The other end of the swing lever 302 then pushes the locking pin 306, overcoming its own weight or elastic resistance, causing it to slide axially until it is completely disengaged from the current limiting hole 300. At this point, the guide device 30 enters the disengaged state. In this state, the upper sorting unit 10 can slide freely along the slide defined by the connecting device 20 under the action of external force, achieving a smooth transition from the aligned state to the misaligned packing state, or the reverse switching.

[0076] This mechanical linkage locking structure offers advantages such as rapid response, reliable operation, and the ability to maintain the locked state without additional energy. The guide device 30 integrates the unlocking action with the sliding preparation; simply applying an external force in the corresponding direction to the lever 304 completes unlocking and release, simplifying the operation process and improving switching efficiency. In logistics scenarios with frequent changes in operating modes, this design significantly enhances the adaptability of the equipment and the user-friendliness of the human-machine interface, while avoiding the complexity, increased costs, and failure risks that electronic or hydraulic locks may bring.

[0077] Overall, the guiding device 30 not only ensures the precise positioning and stable connection of the double-layer sorting unit 10 in key positions, but also provides a solid and reliable mechanical foundation for the whole machine to achieve efficient, safe and flexible state switching.

[0078] Specifically, the locking pin 306 can be set vertically.

[0079] Example 3:

[0080] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0081] The guiding device 30 also includes a guide member 312 formed at the free end of the lever 304;

[0082] The guide component 312 is a guide wheel.

[0083] In this embodiment, based on the aforementioned guiding device 30, a guide member 312 is further provided at the free end of the lever 304. Specifically, this guide member 312 adopts a guide wheel structure, significantly optimizing operational performance and system reliability. The guide wheel, as the guide member 312, has a smooth outer edge and rotates flexibly, enabling it to achieve rolling contact with external driving mechanisms such as misaligned tracks, thereby transforming the potential sliding friction into low-resistance rolling friction. This improvement effectively reduces the driving force required during state switching, making the rotation of the swing lever 302 smoother and more convenient, especially suitable for high-paced sorting scenarios requiring frequent switching between alignment and misaligned packing states.

[0084] Furthermore, the introduction of the guide wheel enhances the stability and durability of the operation. During long-term operation, if a rigid actuating end directly impacts or slides against the drive component, structural deformation, jamming, or even failure can easily occur due to impact or wear. The guide wheel, however, buffers the impact load through its own rotation and evenly distributes contact stress, significantly reducing mechanical wear on components and extending the service life of the guide device 30. Simultaneously, the guide wheel's profile can precisely match a preset trajectory, such as rolling along a specific curved surface or track, thereby achieving precise synchronization between the unlocking timing of the locking pin 306 and the sliding action, avoiding accidental triggering or action delay.

[0085] Example 4:

[0086] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0087] The guide device 30 also includes a tension spring 308, the two ends of which are respectively connected to the upper frame 102 and the lever 304; at the first angle, the swing lever 302 rotates to such that the angle α formed by the line connecting the two ends of the tension spring 308 and the hinge point of the swing lever 302 is ≤180°.

[0088] The guide device 30 can also be switched to an overload state;

[0089] Under the overload condition, the lever 304 drives the swing lever 302 to continue rotating at a second angle based on the first angle, until α > 180°, and the locking pin 306 remains disengaged from the corresponding limiting hole 300.

[0090] In this embodiment, based on the aforementioned structure, the guide device 30 is further equipped with a tension spring 308, one end of which is connected to the upper frame 102 and the other end is connected to the lever 304, forming an elastic linkage mechanism with self-resetting capability and overload protection characteristics. The tension spring 308 works in conjunction with the swing arm 302, the lever 304, and the locking pin 306, which not only optimizes the locking stability under normal working conditions, but also provides mechanical redundancy under abnormal stress conditions, significantly improving the reliability of the system.

[0091] In the initial limiting state, the swing arm 302 is in a natural equilibrium position, and the tension spring 308 is kept moderately preloaded. Its two ends and the hinge point in the middle of the swing arm 302 together form a triangular geometric relationship. At this time, the angle α formed by the lines connecting the three is less than or equal to 180°. In this configuration, the tension force generated by the tension spring 308 applies a restoring torque to the swing arm 302 in the limiting direction, which helps to stably maintain the locking pin 306 in the state of being inserted into the limiting hole 300 of the lower frame 102, effectively resisting vibration or slight disturbance during operation and preventing mis-locking.

[0092] When switching to the disengaged state is required, an external driving force acts on the lever 304, causing it to rotate the swing lever 302 around the hinge axis by a first angle. During this process, the lever 304 does work against the tension of the tension spring 308, which is further stretched. However, the overall geometric relationship remains α ≤ 180°. That is, the tension spring 308 always applies a torque to the swing lever 302 that prevents it from rotating further until the swing lever 302 rotates to the state of α = 180°, at which point the torque is 0. This ensures that the state switch can only be completed when a sufficient and continuous external force is applied, improving the safety and accuracy of the operation.

[0093] The device has overload switching capability. When the upper sorting unit 10 encounters unexpected resistance during sliding, such as foreign objects jamming the track, package obstruction, or drive mechanism failure, while the external driving force continues to act on the lever 304, the lever 304 can drive the swing lever 302 to continue rotating at a second angle based on the first angle, so that the angle α formed by the two ends of the tension spring 308 and the hinge point exceeds 180°. Once this critical point is exceeded, the mechanical behavior of the tension spring 308 changes, and the direction of the tension force that originally hindered the swing is reversed, instead assisting the swing lever 302 to continue rotating, forming a "yielding" mechanism. Under this overload condition, the locking pin 306 remains disengaged from the limiting hole 300 to prevent structural damage caused by forced locking. At the same time, the swing rod 302 can freely deflect with external force to absorb excess energy and protect key components such as the hinge shaft, the guide groove of the locking pin 306, and the connecting device 20 from destructive stress. Furthermore, under the tension of the tension spring 308, the lever 304 can also rotate with the swing rod 302 to an angle that disengages from the external driving element, thus preventing damage to the guide device 30.

[0094] In summary, this three-state working mechanism, which integrates normal locking, controllable unlocking, and overload release, not only enhances the equipment's adaptability in complex logistics environments but also significantly reduces maintenance costs and downtime risks, providing a solid mechanical guarantee for the highly reliable and efficient operation of the double-layer staggered sorting machine.

[0095] Example 5:

[0096] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0097] It also includes a first spring 310, which is adapted to provide a spring force to the locking pin 306 to maintain engagement with the corresponding limiting hole 300. The first spring 310 may be a compression spring sleeved on the locking pin 306. If the locking pin 306 is vertically arranged above the lower frame 102, the lower part of the locking pin 306 has a pin that restricts the downward movement of the compression spring, and the upper part of the locking pin 306 is slidably connected to a connecting seat on the upper frame 102. The position of the compression spring is limited between the pin and the connecting seat, so that when the pin moves upward and disengages from the limiting hole 300, the compression spring deforms and stores force.

[0098] In this embodiment, based on the aforementioned structure, the guide device 30 is further equipped with a first spring 310, which provides a continuous downward elastic force to the locking pin 306, ensuring that it is always reliably inserted into the corresponding limiting hole 300 of the lower frame 102 when there is no external force intervention, thereby maintaining the structural stability of the whole machine in the aligned state. The first spring 310 is preferably a compression spring sleeved on the outer periphery of the locking pin 306, and its arrangement works in coordination with the locking pin 306, the upper frame 102 and the auxiliary limiting structure to form a compact and efficient elastic reset unit.

[0099] Specifically, the locking pin 306 is vertically mounted below the upper frame 102 and directly above the limiting hole 300 of the lower frame 102. The upper end of the locking pin 306 is slidably connected to the connecting seat fixed on the upper frame 102, allowing it to reciprocate only in the vertical direction; the pin forms the bearing surface of the lower end of the spring. The compression spring is sleeved on the outside of the locking pin 306, with its upper end abutting against the bottom surface of the connecting seat and its lower end blocked by the pin, thereby stably confining the spring within the axial space between the connecting seat and the pin.

[0100] In the normal limiting state, the locking pin 306 naturally descends under the preload of the compression spring, its bottom end inserting into the limiting hole 300 of the lower frame 102, achieving rigid positioning of the upper and lower frames 102. When a state switch is required, the lever 304 is driven by an external force, which drives the locking pin 306 to slide upward against the elastic force of the compression spring via the swing lever 302, causing the bottom of the locking pin 306 to disengage from the limiting hole 300. At this time, the compression spring is further compressed, storing elastic potential energy. Once the external driving force is removed or the swing lever 302 returns to its original position, the compression spring releases the stored energy, pushing the locking pin 306 to quickly reset and re-insert into the limiting hole 300, completing the automatic locking.

[0101] This design not only improves the response speed and reset reliability of the locking pin 306, but also effectively avoids the problem of the locking pin 306 becoming dislodged due to insufficient gravity or vibration. Simultaneously, because the compression spring is constrained between the connecting seat and the pin throughout its entire stroke, its working stroke is clearly defined and the force is evenly distributed, making it less prone to skewing, jamming, or fatigue failure, significantly enhancing its long-term durability. Furthermore, this elastic reset mechanism and the swing arm 302 system driven by the tension spring 308 form a dual protection system. The tension spring 308 controls the attitude and overload behavior of the swing arm 302, while the compression spring focuses on ensuring the engagement reliability of the locking pin 306. Their complementary and synergistic functions together construct a highly reliable guide locking system that combines precise positioning, rapid response, self-reset capability, and overload protection. This structure is particularly suitable for sorting scenarios with high dynamic loads, providing crucial support for the stable and efficient operation of double-layer staggered sorting machines.

[0102] Example 6:

[0103] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0104] The swing rod 302 has a connecting groove at one end near the locking pin 306, and the upper end of the locking pin 306 has a head cap. The connecting groove is inserted into the locking pin 306.

[0105] During the process of the guide device 30 switching from the limited state to the disengaged state, the swing rod 302 presses against the head cap, thereby causing the locking pin 306 to disengage from the corresponding limited hole 300. That is, the end of the swing rod 302 forms a fork structure, allowing the locking pin 306 to slide along the opening direction of the fork to match the changing lateral positions of the swing rod 302 and the locking pin 306.

[0106] In this embodiment, when the guide device 30 switches from the limited state to the disengaged state, an external force drives the lever 304, causing the swing lever 302 to rotate around its hinge axis. During this process, the connecting groove of the swing lever 302 pushes the head cap upward, thereby converting the rotational motion into a vertical force on the locking pin 306. The rotation of the swing lever 302 directly presses against the head cap, forcing the locking pin 306 to overcome the elastic force of the first spring 310 and slide upward in the vertical direction until its bottom completely disengages from the limiting hole 300 on the lower frame 102, completing the unlocking action.

[0110] The sliding guide rail 202 extends along the width direction of the sorting unit 10;

[0111] The bracket 204 extends vertically to form an upper packing clearance area above the lower flip plate device 104 in the staggered upper packing state;

[0112] The bracket 204 is slidably connected to the sliding guide rail 202, and the two are respectively fixedly connected to two vertically adjacent frames 102.

[0113] In this embodiment, the connecting device 20 specifically includes a sliding guide rail 202 and a bracket 204, which work together to achieve controllable sliding of the upper and lower sorting units 10 in the width direction. The sliding guide rail 202 extends horizontally along the width direction of the sorting unit 10, providing a stable guiding path for the upper sorting unit 10; the bracket 204 extends vertically and is fixedly connected to the lower frame 102. While structurally supporting the upper frame 102, its height and layout ensure that when the upper sorting unit 10 slides to a misaligned position, an unobstructed packing clearance area is formed directly above the lower flip-plate device 104. The sliding guide rail 202 and the bracket 204 form a sliding pair, allowing relative sliding between them, and are firmly connected to the adjacent upper and lower frames 102, thereby providing the system with the ability to smoothly switch between aligned and misaligned packing states while ensuring overall structural rigidity and operational stability.

[0114] The sliding guide rail 202 and the bracket 204 adopt a modular installation method, with clear force distribution and movement trajectory for each component, effectively avoiding interference or jamming problems common in multi-layer structures. Meanwhile, the vertical extension design of the bracket 204 naturally creates the space window required for packing operations without occupying additional lateral space, making manual pack replenishment, handling of abnormal items, or intervention of the automatic packing mechanism smoother and more efficient. Overall, this connecting device 20 achieves functional switching while also considering structural compactness, operational stability, and human-machine interface friendliness, further strengthening the core advantage of the double-layer staggered flip-top sorting machine in achieving high-density, high-efficiency sorting operations within limited space and cost constraints.

[0115] Example 8:

[0116] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0117] The lower frame 102 includes a first crossbeam 1022 and a second crossbeam 1024 that are fixedly connected to each other and spaced apart front and rear. A corresponding sliding guide rail 202 is fixedly connected to the first crossbeam 1022, and a corresponding flip-up device 104 is connected to the second crossbeam 1024.

[0118] In this embodiment, the lower frame 102 adopts a frame structure including a first crossbeam 1022 and a second crossbeam 1024. The two are arranged at intervals in the front-rear direction and are fixedly connected to each other, together forming the main support skeleton of the lower sorting unit 10.

[0119] The sliding guide rail 202 is firmly installed on the first crossbeam 1022 located on the front side and extends along the width direction of the sorting unit 10, providing a stable and smooth sliding track for the upper frame 102.

[0120] The flip-plate device 104 is installed on the second crossbeam 1024 at the rear. As the core component for performing the sorting action, it undertakes the functions of package guidance and placement. This front-to-back separation layout design, on the one hand, makes the sliding guide rail 202 and the flip-plate device 104 spatially independent of each other, avoiding motion interference, and on the other hand, it also optimizes the load distribution.

[0121] Furthermore, the upper frame 102 adopts a single crossbeam structure, and its position corresponds to the first crossbeam 1022. In this way, the upper flip device 104 and the lower flip device 104 can also be staggered in the front and rear directions, avoiding interference between related components. This also provides a basis for reducing the extension length of the support 204, which is conducive to further reducing the vertical space occupied by the double-layer flip sorting machine.

[0122] When the upper sorting unit 10 slides laterally along the sliding guide rail 202 to the misaligned position, its lower area corresponds precisely to the area above the second crossbeam 1024 and where the flip-board device 104 is located. Since the first crossbeam 1022 is located in front and only supports the guide rail, it does not obstruct the upper operating space. Therefore, a wide and unobstructed working window is naturally formed directly above the lower flip-board device 104. This structural arrangement not only improves the convenience and safety of manual or automatic packing operations but also facilitates equipment maintenance and handling of abnormal parts. Overall, by distributing functional components to the front and rear crossbeams as needed, a reasonable decoupling of mechanical functions is achieved, while maximizing sorting efficiency, structural strength, and human-machine interaction convenience within a limited space. This further enhances the applicability and engineering practicality of the double-layer misaligned flip-board sorting machine in compact logistics scenarios.

[0123] Example 9:

[0124] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0125] The sorting unit 10 also includes a locking device 106, and the flipping device 104 includes a pallet 1042, a support member 1044, and a slide bar 1046.

[0126] The upper ends of the support member 1044 and the slide rod 1046 are hinged at intervals to the bottom of the support plate 1042 along the front-back axis;

[0127] The lower end of the support member 1044 is hinged to the frame 102 along the front-rear axis, and the lower end of the slide rod 1046 is vertically slidably connected to the frame 102.

[0128] The flip-board device 104 can switch between the running state and the unloading state; in the running state, the support member 1044 and the slide bar 1046 are parallel, the tray 1042 extends laterally to support the package, and the vertical position of the slide bar 1046 relative to the frame 102 is locked in a high position by the locking device 106.

[0129] In the unloading state, the locking device 106 releases the locking relationship between the slide bar 1046 and the vertical position of the frame 102. The slide bar 1046 slides down to the low position relative to the frame 102, and the upper end of the support member 1044 tilts towards the slide bar 1046, so that the side of the tray 1042 close to the slide bar 1046 tilts downward to realize unloading.

[0130] In this embodiment, the sorting unit 10 is further equipped with a locking device 106, which works in conjunction with the flip-board device 104 to achieve reliable switching between the running state and the unloading state.

[0131] The flip-up device 104 includes a support plate 1042, a support member 1044, and a sliding rod 1046. Its structural layout fully considers the kinematic relationship and the simplicity of functional realization. Specifically, the upper ends of the support member 1044 and the sliding rod 1046 are hinged to the bottom of the support plate 1042 at intervals along the front-rear axis, forming a variable-angle linkage mechanism; the lower end of the support member 1044 is also hinged to the frame 102 along the front-rear axis, forming a fixed fulcrum, while the lower end of the sliding rod 1046 forms a vertical sliding connection with the frame 102, allowing it to move relative to the frame in the vertical direction.

[0132] In operation, the locking device 106 locks the slide bar 1046 in a high position relative to the frame 102. At this time, the support member 1044 remains parallel to the slide bar 1046, and the pallet 1042 extends horizontally to stably support the packages to be sorted, ensuring a smooth and reliable conveying process. Once the unloading action needs to be performed, the locking device 106 actively releases the constraint on the slide bar 1046. Under the action of gravity, the slide bar 1046 slides vertically along the frame 102 to a low position, causing the pallet 1042 to descend synchronously on the side close to the slide bar 1046. At the same time, since the lower end of the support member 1044 is a fixed hinge point, its upper end tilts towards the slide bar 1046 as the pallet 1042 moves. The tilted surface, with one side higher than the other, guides the package to slide smoothly into the corresponding compartment, completing the precise unloading.

[0133] This flip-plate mechanism cleverly utilizes the linkage 1062 and the slider principle. Without a complex drive system, the vertical displacement of the slide bar 1046 alone allows for controllable changes in the pallet 1042's posture. It features a simple structure, rapid response, and low failure rate. Combined with the precise control of the locking device 106, it not only ensures the rigid support capacity of the pallet 1042 during operation but also guarantees the timeliness and reliability of the unloading action. Furthermore, since all hinge points are arranged along the front-to-back direction, spatial interference with adjacent sorting units 10 or the unloading operation area is effectively avoided. Overall, this flip-plate device 104 ensures high sorting efficiency while also considering operational stability, structural compactness, and ease of maintenance, providing crucial support for the long-term reliable operation of the double-layer staggered flip-plate sorting machine in high-density working environments.

[0134] It also includes a slider 32, which is fixedly connected to the frame 102, and the slide rod 1046 is vertically slidably connected to the corresponding slider 32. The slider 32 can be a linear bearing.

[0135] To further improve the guiding accuracy and operational stability of the slide bar 1046, the sorting unit 10 also includes a sliding member 32, which is fixedly mounted on the frame 102. The slide bar 1046 and the corresponding sliding member 32 form a vertical sliding connection, ensuring that the slide bar 1046 is always precisely constrained during its up-and-down movement, effectively suppressing undesirable phenomena such as swaying, jamming, or wear. Preferably, the sliding member 32 can be a linear bearing, which has advantages such as low friction, high rigidity, long life, and maintenance-free or low-maintenance, ensuring that the slide bar 1046 maintains smooth and stable sliding performance during frequent reciprocating motion.

[0136] By introducing a sliding element 32, such as a linear bearing, the stress state of the slide bar 1046 is significantly improved—transforming the concentrated load that might have acted on the wall of the frame 102 hole into a uniform load borne by a dedicated guiding element, thus extending the service life of the entire structure. Simultaneously, the response speed and positioning accuracy of the flip-board device 104 when switching between the running state and the unloading state are also improved. Especially under high-speed sorting conditions, the rapid and accurate resetting of the pallet 1042's posture is crucial for the sorting cycle and the accuracy of package placement, and the high-precision sliding guide system is the key guarantee for achieving this goal.

[0137] Furthermore, the modular design of the sliding component 32 facilitates installation, replacement, and adjustment. Even after long-term use and wear, only a single linear bearing needs to be replaced, without disassembling the entire frame 102 structure, significantly reducing maintenance costs and downtime. Combined with the aforementioned scheme of indirectly driving the upper slide bar 1046 via the drive rod 108, the sliding component 32 further ensures that the upper and lower slide bars 1046 maintain good coaxiality and motion consistency when moving independently, providing solid support for the high reliability, high efficiency, and easy maintenance of the double-layer staggered flip-top sorting machine.

[0138] Example 10:

[0139] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0140] The slide bar 1046 of the upper sorting unit 10 extends downward so that the lower end height of the slide bar 1046 of the upper sorting unit 10 is consistent with that of the slide bar 1046 of the lower sorting unit 10 when in operation or unpacking state. In this way, when used with the reset device, the slide bars 1046 corresponding to the two sorting units 10 have a high degree of consistency, which makes it easy to reset both slide bars 1046 to the high position through a set of reset devices, thereby making it easy for the two flip-plate devices 104 to be reset to the operating state.

[0141] In this embodiment, the slide bar 1046 of the upper sorting unit 10 extends downwards in its structural design, so that its lower end is at approximately the same height as the lower end of the slide bar 1046 of the lower sorting unit 10 when in operation or unloading state. This height consistency is not accidental, but rather the result of precise structural optimization, aimed at providing uniform hardware conditions for subsequent reset operations. After the lower ends of the two slide bars 1046 are aligned, a reset device, such as a cylinder, lifting platform, or ramp, is configured. The same reset device can be used to simultaneously act on the upper and lower slide bars 1046, synchronously lifting or pulling them back to the high-position locking position, thereby efficiently and reliably driving the two-layer flip-plate device 104 to synchronously return to the horizontal support operating state.

[0142] This design significantly simplifies the complexity of the reset system. On the one hand, it avoids the problems of increased space occupation, complex control logic, and increased costs associated with setting up independent reset mechanisms for the upper and lower layers. On the other hand, it improves the consistency and synchronization of system actions, reducing the risk of pallet 1042 posture deviation or jamming due to untimely reset. Especially in high-frequency sorting operations, fast and stable reset capability is directly related to the overall machine cycle time and reliability. This structure, through the reasonable extension of the length of the slide bar 1046, cleverly achieves the motion coordination of multiple layers of actuators, demonstrating good modularity and scalability. In addition, the highly consistent ends of the slide bar 1046 also provide convenience for maintenance and debugging. Technicians can inspect or intervene in the two-layer mechanism through a unified operating window, further enhancing the serviceability of the equipment. Overall, this design not only strengthens the functional integration of the double-layer staggered flip-board sorter but also lays a solid mechanical foundation for achieving high-efficiency, low-failure-rate continuous sorting operations.

[0143] Example 11:

[0144] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0145] The lower sorting unit 10 also includes a drive rod 108 that is vertically slidably connected to the frame 102, such as being slidably connected to the first crossbeam 1022, to avoid interference with the lower flip device 104; in the unpacking state, the lower end of the drive rod 108 and the lower end of the slide bar 1046 of the lower sorting unit 10 are at the same height.

[0146] The lower end of the slide bar 1046 of the upper sorting unit 10 can abut against the upper end of the drive rod 108, so that the drive rod 108 can slide upward, driving the slide bar 1046 of the upper sorting unit 10 to slide upward, thereby enabling the upper flip-plate device 104 to reset from the lower package state to the operating state. This solution can replace the above-mentioned solution of extending the upper slide bar 1046, which is beneficial to improving the dimensional consistency and interchangeability of the upper slide bar 1046 and the lower slide bar 1046. At the same time, the shorter slide bar 1046 will be more stable when sliding, improving the overall stability of the device.

[0147] In this embodiment, a drive rod 108 is vertically slidably connected to the frame 102 of the lower sorting unit 10, for example, at the first crossbeam 1022. Its placement is carefully considered to avoid the area where the lower flip-board device 104 is located, thus effectively preventing structural interference during movement. The lower end of the slide bar 1046 of the upper sorting unit 10 is designed to abut against the upper end of the drive rod 108. When it is necessary to reset the upper flip-board device 104 from the unpacked state to the operating state, the actuator acts on the drive rod 108, causing it to slide upwards vertically. The upper end of the drive rod 108 then pushes the upper slide bar 1046 upwards synchronously, causing the pallet 1042 to rotate around the hinge point of the support member 1044, ultimately restoring the pallet 1042 to a horizontal position, completing the reset action.

[0148] Specifically, this structure replaces the previous solution of achieving height alignment by extending the upper slide bar 1046, offering multiple advantages. First, the upper and lower slide bars 1046 can use the same length and structural form, significantly improving the dimensional consistency and interchangeability of components, which is beneficial for mass production, inventory management, and subsequent maintenance. Second, the shorter slide bar 1046 experiences more concentrated force and more stable guidance during vertical sliding, making it less prone to bending or wobbling, thereby improving the repeatability of the flip-board action and the overall operational reliability of the mechanism. Furthermore, the driving function is undertaken by an independently set drive rod 108, allowing the slide bar 1046 itself to focus on transmitting the displacement required for attitude changes, resulting in a clearer division of functions and reducing the structural complexity of individual components.

[0149] In addition, the lower ends of the drive rod 108 and the lower slide rod 1046 can also be reset by a set of actuators, so as to efficiently and reliably drive the two-layer flip plate device 104 to synchronously return to the horizontal support operating state.

[0150] Example 12:

[0151] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0152] The locking device 106 is supported on the frame 102;

[0153] The locking device 106 includes a connecting rod 1062 and a second spring 1064;

[0154] The connecting rod 1062 is laterally slidably connected to the frame 102. One end of the connecting rod 1062 is the locking end close to the slide rod 1046, and the other end is the operating end away from the slide rod 1046.

[0155] The slide bar 1046 is provided with a locking part, such as a through hole or a blind hole;

[0156] The link 1062 can slide toward the slide bar 1046 so that when the slide bar 1046 is in the high position, the locking end is inserted into the locking part;

[0157] The connecting rod 1062 can also slide away from the slide rod 1046 so that when the slide rod 1046 is in the high position, the locking end disengages from the locking part, thereby causing the slide rod 1046 to drop to the low position by gravity.

[0158] The second spring 1064 deforms and stores force when the connecting rod 1062 slides away from the slide rod 1046, so as to provide the connecting rod 1062 with a sliding force towards the slide rod 1046.

[0159] The locking device 106 also includes a rotating plate 1066, the middle of which is hinged to the frame 102, and one end of the rotating plate 1066 is engaged with the operating end of the connecting rod 1062.

[0160] When the other end of the rotating plate 1066 is pressed, the rotating plate 1066 drives the connecting rod 1062 to slide away from the end of the slide rod 1046, causing the locking end to disengage from the locking part, and then causing the slide rod 1046 to drop to a low position due to gravity.

[0161] In this embodiment, the connecting rod 1062 is laterally slidably connected to the frame 102. One end of the connecting rod is a locking end near the slide rod 1046, and the other end extends to a position that facilitates external driving or manual intervention. A locking part is correspondingly provided on the body of the slide rod 1046, and the position of the locking part is precisely matched with the spatial position of the locking end of the connecting rod 1062 when the slide rod 1046 is in the high position.

[0162] When the slide bar 1046 is pushed to the high position by the reset mechanism, under the preload of the second spring 1064, the connecting rod 1062 automatically slides towards the slide bar 1046, so that its locking end is inserted into the locking part on the slide bar 1046, thereby firmly locking the slide bar 1046 in the high position, ensuring that the pallet 1042 of the flip plate device 104 maintains a horizontal supporting posture when in operation, effectively preventing accidental falling due to vibration or load disturbance.

[0163] When the unloading action is required, an external force, such as a cylinder push rod, an electromagnet, or manual operation, is applied to the operating end of the connecting rod 1062 to overcome the elastic force of the second spring 1064, causing the connecting rod 1062 to slide away from the slide bar 1046, and the locking end disengages from the locking part; at this time, the slide bar 1046 is unrestrained and slides vertically down to the low position along the sliding member 32 under its own weight and the weight of the support plate 1042, causing the support plate 1042 to tilt and complete the unloading.

[0164] The second spring 1064 serves a reset and self-locking function during this process. When the external force is removed, the second spring 1064 releases its stored elastic potential energy, pushing the connecting rod 1062 to automatically return to its original position, preparing for the next high-position locking. This passive locking mechanism based on the energy stored in the mechanical second spring 1064 can maintain the locked state without continuous power supply, and has the advantages of high reliability, low energy consumption, and strong anti-interference ability. It is particularly suitable for logistics sorting scenarios with frequent starts and stops and complex environments.

[0165] Furthermore, the locking device 106 features a compact layout, with all moving parts located on the side of the frame 102, without occupying the flapping area. The unlocking device 90, used for unlocking, also avoids encroaching on the area of ​​the slide bar 1046, preventing interference with the package conveying path, the loading operation space, or the slide bar 1046. Simultaneously, the lateral sliding direction of the connecting rod 1062 is orthogonal to the vertical movement direction of the slide bar 1046, resulting in clear motion decoupling and further enhancing the determinism and durability of the mechanism's actions. Overall, this locking scheme achieves a closed-loop function of "self-locking upon arrival, trigger release, and automatic reset" with a minimalist mechanical structure. This not only ensures the accuracy and reliability of the flapping device 104 switching between two working states but also provides strong support for the modular design, mass production, and long-term stable operation of the entire machine.

[0166] Specifically, a ball bearing can be additionally provided on the locking end to reduce friction between it and the slide bar 1046 and improve the smoothness of its contact with the slide bar 1046.

[0167] Example 13:

[0168] Figures 1-9 In addition to providing a sorting and transport line, the embodiments of this utility model include a line body 40 and a double-layer staggered flip-type sorting machine as described in the above embodiments. Along the extension direction of the line body 40, multiple lower sorting units 10 are connected end to end.

[0169] It also includes a misaligned guide rail 50, which corresponds to the height position of the upper sorting unit 10 and is suitable for cooperating with the guide device 30 to switch the corresponding double-layer misaligned flip-board sorting machine to the misaligned packing state.

[0170] In this embodiment, the line 40 is arranged in a ring as the main conveying channel, and the double-layer staggered flip-plate sorting machine is supported on the line 40 by the bottom walking wheels, power wheels and limit wheels.

[0171] The misalignment guide rail 50 can be partially installed along the extension direction of the line 40, and its position corresponds to the position of the upper sorting unit and cooperates with the guide device 30 on the upper frame 102. When the upper sorting unit 10 moves with the line 40 to the section with the misalignment guide rail 50, the guide device 30 contacts the misalignment guide rail 50 and is guided by it, forcing the upper frame 102 to slide laterally in the width direction, thereby causing the entire upper sorting unit 10 to be misaligned relative to the lower unit by a predetermined amount, entering the misaligned packing state, forming a clear and unobstructed operating space above the lower flip device 104, which is convenient for manual packing, abnormal handling or automatic packing equipment intervention.

[0172] This design, combining a fixed line body 40 with a switchable sorting unit 10, enables the entire sorting and transport line to maintain high-density, high-cycle automated sorting capabilities while flexibly providing the physical space required for human-machine collaboration at specific workstations. The offset guide rail 50, acting as an external triggering mechanism, achieves state switching without additional electrical control or complex sensors. It is structurally reliable, responds promptly, and its placement and length are easily adjusted according to on-site process requirements. Furthermore, since only the upper-level unit participates in lateral movement, while the lower-level unit remains fixedly connected, the continuity and rigidity of the main conveyor path are ensured, preventing sorting accuracy from being affected by overall structural swaying.

[0173] Example 14:

[0174] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0175] The misaligned guide rail 50 includes a lead-out section 502, the upstream end of which is inclined outward in the width direction of the line body 40.

[0176] The corresponding guide device 30 can guide the double-layer staggered flip-board sorting machine into the staggered loading state along the lead-out section 502.

[0177] The lead-out section 502 can be a baffle located inside the guide device 30, used to cooperate with the guide 312 to move the upper unit 10 to the misaligned position, thereby realizing the switching of the double-layer misaligned flip-board sorting machine from the aligned state to the misaligned packing state.

[0178] Since the misaligned guide rail 50 is located on the baffle inside the guide member 312, it will affect the inward swinging action of the guide member 312, and therefore will not affect the guide device 30 from switching to the overload state.

[0179] Example 15:

[0180] Reference Figures 1-9In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0181] The misaligned guide rail 50 also includes a retaining section 504, with the downstream end of the lead-out section 502 connected to the upstream end of the retaining section 504;

[0182] The corresponding guide device 30 can enter the holding section 504 along the lead-out section 502 so that the double-layer staggered flip-board sorting machine can enter and maintain the staggered loading state.

[0183] The retaining section 504 can be a baffle located inside the guide device 30, and it can be connected to the lead-out section 502 to maintain the stability of the upper sorting unit 10 in the misaligned position and improve its vibration resistance.

[0184] Example 16:

[0185] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0186] The misaligned guide rail 50 also includes a reset section 506, the downstream end of which is inclined outward in the width direction of the line body 40.

[0187] When the double-layer staggered flip-board sorting machine is in the staggered unpacking state and running along the line 40, the corresponding guide device 30 can enter the reset section 506 to reset the double-layer staggered flip-board sorting machine to the aligned state.

[0188] The reset section 506 is a baffle located outside the guide device 30, used to guide the guide 312 back to its original alignment position, thereby realizing the switching of the double-layer misaligned flip-plate sorting machine from the misaligned packing state to the aligned state.

[0189] Example 17:

[0190] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0191] Line 40 is a loop and includes a straight segment 402 and an arc segment 404;

[0192] The misaligned guide rail 50 corresponds to the position of the straight segment 402;

[0193] The double-layer staggered flip-plate sorting machine reaches a threshold speed on the line body 40 so that when the double-layer staggered flip-plate sorting machine is in a staggered packing state, it can use centrifugal force to reset to the aligned state when it runs to the arc segment 404.

[0194] In this embodiment, a centrifugal force reset technique is adopted. Based on this, the double-layer flip-plate sorting machine can be reset from a misaligned packaging state to an aligned state without setting a reset section 506, simplifying the overall structure of the sorting and transport line and reducing costs. The specific speed threshold can be determined experimentally and will not be detailed here.

[0195] Example 18:

[0196] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0197] It also includes a reset member 60, which is adapted to reset the flipping device 104, which is in the lower package state, to the conveying state when the double-layer flipping conveyor is running along the line 40.

[0198] The reset member 60 includes a slope plate extending along the length direction of the line body 40, with the downstream end of the slope plate inclined upward.

[0199] When the tipper conveyor runs along the line 40 to the slope, the lower end of the slide bar 1046, which is in a low position, can climb up the slope, thereby resetting the tipper device 104 to the conveying state.

[0200] In this embodiment, to ensure that the flip-board device 104 can reliably and automatically return to the horizontal conveying state after completing the unloading action, the sorting and transport line is also equipped with a reset component 60. Its function is to perform passive reset on the flip-board device 104, which is still in the unloading state, i.e., the slide bar 1046 is in the low position, during the operation of the double-layer staggered flip-board sorting machine with the line body 40. The reset component 60 specifically includes a ramp extending along the length direction of the sorting line body 40. Its structure is simple, requires no external power, and cleverly utilizes the movement of the equipment itself to achieve a functional closed loop.

[0201] The ramp is located in a specific section of line 40, with its downstream end sloping upwards to form a gently rising incline. When the double-layer staggered flip-top sorter moves along the conveying direction to the ramp position, if its flip-top device 104 is still in the unloading state, the bottom end of the slide rod 1046 will contact the incline of the ramp and climb upwards along the slope as the sorter continues to move forward. This climbing process forces the slide rod 1046 to slide vertically upwards relative to the frame 102, which in turn drives the pallet 1042 to rotate around the hinge point of the support member 1044 through the linkage 1062 mechanism, ultimately restoring the pallet 1042 to a horizontal position, completing the automatic reset from the unloading state to the conveying state.

[0202] This reset mechanism has multiple advantages. First, it relies entirely on mechanical contact, requiring no additional electrical, pneumatic, or sensor systems, resulting in a simple structure, low cost, and high reliability. Second, the inclination angle of the ramp is optimized to ensure the effectiveness of the reset while avoiding impacts or jamming caused by excessively steep slopes, thus ensuring smooth and gentle operation. Third, since the reset action occurs during the operation of the sorting machine, there is no need to stop the machine or wait for instructions, significantly improving the cycle time and continuity of the entire production line.

[0203] In addition, the ramp, as a universal reset element, can be applied to the upper and lower sorting units 10, provided that the lower ends of the slide bar 1046 are at the same height or act indirectly through the drive rod 108, which further enhances the consistency and maintainability of the system.

[0204] Example 19:

[0205] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0206] It also includes a control device 70, an identification device 80, and an unlocking device 90 that are interconnected.

[0207] The identification device 80 is installed to identify each package;

[0208] The unlocking device 90 is adapted to selectively unlock the locking device 106 to lock the slide bar 1046;

[0209] The control device 70 can receive the identification information from the identification device 80 and control the unlocking device 90 to release the lock on the slide bar 1046, thereby enabling the flip device 104 to switch from the conveying state to the unloading state to complete the unloading.

[0210] In this embodiment, the sorting and transport line further integrates a collaborative control system consisting of a control device 70, an identification device 80, and an unlocking device 90 to achieve precise and on-demand triggering of the unloading action of the flip-board device 104. The identification device 80 is arranged upstream of each sorting slot along the sorting line 40 to collect the identity information of passing packages in real time and transmit the identification results to the control device 70. The control device 70, acting as the system's central hub, determines whether the current package needs to be unloaded at this workstation based on preset sorting logic and sends a control signal to the unlocking device 90 at the corresponding location accordingly.

[0211] The unlocking device 90 is mechanically linked to the aforementioned locking device 106, and its function is to selectively release the constraint of the locking device 106 on the slide bar 1046. Specifically, when the control device 70 determines that a double-layer staggered flip-top sorting machine needs to perform a package unloading action, it drives the unlocking device 90 to act, for example, by using a cylinder push rod, to act on the operating end of the connecting rod 1062 in the locking device 106, causing it to overcome the force of the second spring 1064 and slide away from the slide bar 1046, thereby pulling the locking end out of the locking part of the slide bar 1046. Once the lock is released, the slide bar 1046 slides vertically down to the lower position along the sliding member 32 under the action of the tray 1042 and its own gravity, causing the tray 1042 to tilt, so that the package slides smoothly into the designated compartment, completing the precise unloading.

[0212] This control logic ensures that the unloading action is triggered only at the workstations where sorting is required. The flip-board device 104 at other workstations remains locked in the conveying state, maintaining the pallet 1042 horizontally and ensuring the continuity and stability of the main line conveyor. At the same time, since the unlocking action is precisely controlled by electronic signals, the response is rapid and the timing is accurate, which can seamlessly match the 40-cycle operation of the high-speed line, avoiding false triggering or missed triggering.

[0213] This electronically controlled unlocking mechanism complements the aforementioned mechanical reset mechanism. The lower-level mechanism is triggered by intelligent identification and active control, while the reset relies on a passive mechanical structure for automatic completion. This ensures both the flexibility and intelligence of sorting decisions while maintaining the high reliability and low maintenance of the reset process. Furthermore, the unlocking device 90 can be designed as a modular unit, corresponding one-to-one with each sorting machine, facilitating independent debugging, fault isolation, and future expansion.

[0214] Example 20:

[0215] Reference Figures 1-9 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions:

[0216] It also includes abnormal and normal bottom wrapping grids located on the 40-width side of the line body;

[0217] The identification device 80 includes a first scanning device 802 and a second scanning device 804;

[0218] The first scanning device 802 is adapted to scan the package during loading so that the package corresponds one-to-one with each sorting unit 10;

[0219] The second scanning device 804 is adapted to scan packages when the double-layer staggered flip-top sorter is in an aligned state.

[0220] When the scanning results of the first scanning device 802 and the second scanning device 804 are consistent, or when the second scanning device 804 has no scanning result, the scanning result of the first scanning device 802 is determined to be correct, thereby enabling the corresponding sorting unit 10 to unpack in the normal unpacking slot.

[0221] When the scanning results of the first scanning device 802 and the second scanning device 804 are inconsistent, it is determined that the scanning of the first scanning device 802 and the second scanning device 804 is abnormal, and the corresponding sorting unit 10 is controlled to unpack the abnormal packing compartment.

[0222] In this embodiment, the normal package receiving compartment is used to receive regular packages with clear information and routes; the abnormal package receiving compartment is specifically used to temporarily store packages with barcode recognition conflicts, missing information, or suspected misdelivery, so as to facilitate subsequent manual review or repackaging, thereby effectively preventing last-mile delivery errors caused by missorting or omission.

[0223] The first scanning device 802 is arranged at the packing station, usually near the entrance or operating table of the staggered packing area. It is used to scan the package label information as soon as the package is placed on the upper or lower flip device 104 by manual or automatic equipment. The scanning result serves as the initial sorting instruction and is bound to the currently placed sorting unit 10, that is, "this package should be sorted by this sorting unit 10".

[0224] Subsequently, when the double-layer staggered flip-top sorting machine moves with line 40 to the conveyor section and is in an aligned state, the second scanning device 804, typically mounted above or on the side fixed bracket 204 of line 40, scans the same package again. This secondary scan aims to verify whether the package has been displaced, flipped, obstructed, or misread during the conveying process, and to confirm whether its current physical position is consistent with the initial allocation logic.

[0225] The system compares and judges the results of the two scans through the control device 70:

[0226] If the identification results of the first scanning device 802 and the second scanning device 804 are consistent, it indicates that the package information is stable and the position is correct. The system determines that the initial sorting instruction is valid and controls the corresponding sorting unit 10 to perform the unloading action when it reaches the target slot, and sends the package into the normal unloading slot.

[0227] If the second scanning device 804 fails to read any information, but the first scan has a valid record, the system will default to the first identification and still regard it as a valid package, guiding it to the normal packing slot to avoid unnecessary abnormal diversion caused by accidental reading failure.

[0228] If the two scan results are inconsistent, the system determines that there is an information conflict or that the package has been misdelivered, which poses a sorting risk. The system immediately triggers the abnormal handling process, controls the corresponding sorting unit 10 to guide the package to the abnormal lower compartment, and hands it over to manual intervention for verification.

[0229] This dual verification mechanism significantly improves the fault tolerance and data reliability of the sorting system. On the one hand, it effectively filters out potential errors caused by loading operation mistakes, temporary barcode obstruction, or momentary scanning interference; on the other hand, by centralizing abnormal packages, it prevents them from mixing into the normal flow and causing a chain of errors, greatly reducing the cost of subsequent error correction. At the same time, this logical design balances efficiency and safety, ensuring high accuracy without being overly sensitive to single scan failures, thus maintaining the smoothness of the main line sorting.

[0230] Furthermore, since the first scan occurs during the stationary or low-speed phase of the misaligned package loading state, the recognition success rate is high; the second scan is completed in the stable transport section during the aligned state, with minimal environmental interference. The two scans complement each other in time and space, jointly constructing a practical package identification verification system. Combined with the aforementioned electronic unlocking, mechanical reset, and state switching structures, the entire sorting and transportation line not only achieves efficient space utilization and high-density layout, but also reaches an advanced level in terms of intelligence, accuracy, and anomaly handling capabilities for small and medium-sized logistics scenarios.
