Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically to a logistics conveying track and logistics transport equipment. Background Technology

[0002] Against the backdrop of rapid industrialization and automated logistics development, rail-mounted transport systems have become core equipment for material handling due to their high efficiency and stability, and are widely used in various scenarios such as urban underground logistics and industrial production sorting. In actual transportation, materials often need to be reversed at a 90-degree angle between straight tracks in different directions, and the smoothness of this process directly affects the transportation efficiency and operational stability of the entire logistics system.

[0003] Currently, the mainstream right-angle reversing solutions mainly include two types: track turntable steering and longitudinal / transverse track switching. While the track turntable steering solution is technically mature and has no special requirements for transport vehicles, it has significant drawbacks: it requires complex underground concrete foundations, resulting in high initial construction costs; each reversal requires a complete process of "loading-stopping-rotating-aligning-unloading," leading to efficiency bottlenecks; furthermore, the bearings, gears, and other components of the rotating mechanism require regular maintenance, resulting in high long-term maintenance costs; and it also faces the risk of a single point of failure paralyzing the entire intersection's transport. The longitudinal / transverse track switching solution relies on special vehicles with bidirectional driving capabilities, whose manufacturing costs are far higher than ordinary track flatcars. It also requires highly skilled maintenance personnel, and the switching action requires additional buffer space, limiting its applicability. Therefore, the existing technology needs improvement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a logistics transmission track and logistics conveying equipment.

[0005] To solve the above-mentioned technical problems, in a first aspect, the present invention provides a logistics transmission track, comprising:

[0006] The first straight conveying unit is arranged along a first direction and includes a fixed section, a first movable section, and a lifting drive assembly that is drivenly connected to the first movable section. The first movable section is configured to be able to lift and lower relative to the fixed section to a first position and a second position. When the first movable section is in the first position, the fixed section is connected to the first movable section. When the first movable section is in the second position, the fixed section is disconnected from the first movable section.

[0007] A second straight conveying unit is arranged along a second direction, which is perpendicular to the first direction.

[0008] A corner reversing unit is disposed between the first straight conveying unit and the second straight conveying unit, and is configured to have a first docking state and a second docking state. When the corner reversing unit is in the first docking state, it docks with the first straight conveying unit, and when the corner reversing unit is in the second docking state, it docks with the second straight conveying unit.

[0009] In one possible implementation, the first straight conveying unit further includes a second movable section, which is drive-connected to the upgrade drive assembly and is spaced vertically from the first movable section.

[0010] In one possible implementation, the corner reversing unit includes:

[0011] A corner track frame, which is movably configured and has a first state connected to the first straight conveyor unit and a second state connected to the second straight conveyor unit;

[0012] A reversing drive assembly is used to drive the corner track frame to adjust its position so that the corner track frame switches between a first state and a second state.

[0013] In one possible implementation, the commutation drive assembly includes a first support frame, a linear drive module disposed on the first support frame, and a second support frame, wherein the second support frame is slidably connected to the first support frame and is drively connected to the linear drive module.

[0014] In one possible implementation, the linear drive module includes a first drive motor, a lead screw, and a nut slider that is driven by the lead screw, the nut slider being fixedly connected to the second support frame.

[0015] In one possible implementation, the second support frame has a clearance hole in the middle, and the reversing drive assembly further includes a rotary drive module, the output end of which passes through the clearance hole and is fixedly connected to the corner track frame.

[0016] In one possible implementation, the rotary drive module includes a second drive motor, a transmission gear, and an output flange connected to the transmission gear, the output flange being fixedly connected to the corner track frame.

[0017] In one possible implementation, the lifting drive assembly includes a lifting fixed frame, a first drive module, and a second drive module. The first drive module and the second drive module are configured to move up and down along the lifting fixed frame. The first drive module is fixedly connected to the first movable section, and the second drive module is fixedly connected to the second movable section.

[0018] In one possible implementation, a rack is provided on one side of the lifting and fixing frame, and the first drive module and / or the second drive module are connected to the lifting and fixing frame via the rack.

[0019] To achieve the same inventive objective, in a second aspect, the present invention also provides a logistics conveying device, comprising a logistics conveying track as described in the first aspect and a conveying container slidably connected to the logistics conveying track.

[0020] Compared to existing technologies, the logistics transport track provided by this invention includes a first straight-line conveying unit, a second straight-line conveying unit, and a corner reversing unit. The first straight-line conveying unit is arranged along a first direction and consists of a fixed section, a first movable section, and a lifting drive assembly. The lifting drive assembly is drively connected to the first movable section to drive it to rise and fall relative to the fixed section to a first docking position or a second disconnected position. The second straight-line conveying unit is fixedly arranged along a second direction perpendicular to the first direction. The corner reversing unit is located between the two straight-line conveying units and has a first docking state with the first straight-line conveying unit and a second docking state with the second straight-line conveying unit. Thus, this application achieves efficient reversing between tracks in different directions by using a segmented first straight-line conveying unit in conjunction with a corner reversing unit that can switch docking states. The first straight-line conveying unit achieves rigid docking or precise disconnection between the movable and fixed sections through the lifting drive assembly. Combined with the corner reversing unit's state switching between the two straight-line units, this effectively reduces the docking gap problem common in traditional reversing structures, avoids the risk of material deviation and derailment during transport, reduces impact vibration and noise, and ensures transportation safety. Furthermore, the lifting drive component occupies less space than the rotating mechanism. The segmented design and compact layout of the corner unit make the overall structure more suitable for space-constrained scenarios such as industrial workshops and warehouses, eliminating the need for additional buffer space and expanding its applicability.

[0028] Example 1

[0029] Please see the appendix Figure 1-4 This embodiment provides a logistics transmission track, including a first straight conveying unit 100, a second straight conveying unit 200, and a turning and reversing unit 300.

[0030] The first linear conveying unit 100 is arranged along a first direction (exemplarily the X direction, laterally) and includes a fixed section 110, a first movable section 120, and a lifting drive assembly 130. The fixed section 110 is the basic conveying part of the conveying unit and is a fixedly installed track. The conveying structure of the first movable section 120 matches that of the fixed section 110, and it is lifted and lowered relative to the fixed section 110 by the lifting drive assembly 130. When the first movable section 120 is in the first position, its top surface is flush with the top surface of the fixed section 110, and the two are connected to form a continuous conveying line. When the first movable section 120 rises or falls to the second position under the drive of the lifting drive assembly 130, it is disconnected from the fixed section 110.

[0031] The second straight conveying unit 200 is arranged along a second direction (exemplarily the Y direction, longitudinal direction), which is perpendicular to the first direction. Its structure can be the same as the fixed section 110 of the first straight conveying unit 100. It is a fixed straight conveying structure used to receive materials transferred from the corner reversing unit 300.

[0032] A corner reversing unit 300 is located at the intersection of the first straight conveying unit 100 and the second straight conveying unit 200 to realize the material reversing and transfer between the two. The corner reversing unit 300 has a first docking state and a second docking state: in the first docking state, its input end docks with the output end of the first straight conveying unit 100 to receive materials from the first straight conveying unit 100; in the second docking state, its output end docks with the input end of the second straight conveying unit 200 to transfer materials to the second straight conveying unit 200.

[0033] Example 2

[0034] Based on Embodiment 1, this embodiment optimizes the first linear conveying unit 100 by adding a second movable section 140. The second movable section 140 is connected to the lifting drive assembly 130 and is vertically spaced from the first movable section 120. The lifting actions of both can be independently controlled by the lifting drive assembly 130.

[0035] Specifically, the lifting drive assembly 130 includes a lifting fixed frame 131, a first drive module 132, and a second drive module 133. The lifting fixed frame 131 has a frame structure with a rack 1311 on one side along the height direction. Both the first drive module 132 and the second drive module 133 include a drive motor and a gear meshing with the rack 1311. Both are slidably connected to the guide rail of the lifting fixed frame 131 via sliders. The lower end of the first drive module 132 is fixedly connected to the first movable section 120, and the lower end of the second drive module 133 is fixedly connected to the second movable section 140. Through the meshing transmission of the gear and the rack 1311, the independent lifting of the first movable section 120 and the second movable section 140 is realized.

[0036] This structure enables independent operation of two lines and multi-height coordinated conveying, significantly improving operational flexibility and efficiency. For example, when a conveying container loaded with material reaches the first movable section 120, it can be controlled to descend to the second position for unloading. Simultaneously, the lifting drive assembly 130 controls the second movable section 140 to move to the first position, connecting with the fixed section 110 to form a continuous conveying line, ensuring the normal passage of other conveying containers and achieving parallel unloading and conveying operations. Furthermore, it can be configured so that the first movable section 120 connects to the fixed section 110 for lower-level lateral conveying, and the second movable section 140 rises to connect to the upper-level conveying structure for upper-level lateral conveying. This dual-line synchronous transfer of multiple batches of materials is suitable for scenarios such as high-density sorting and parallel conveying of multiple types of materials.

[0037] Example 3

[0038] This embodiment provides a detailed description of the structure of the corner reversing unit 300, which includes a corner track frame 310 and a reversing drive assembly 320.

[0039] The corner track frame 310 is a flat frame with guide rails. Its conveying surface structure matches the conveying surfaces of the first and second straight conveying units. It has a first state connected to the first straight conveying unit 100 and a second state connected to the second straight conveying unit 200.

[0040] The reversing drive assembly 320 includes a first support frame 321, a linear drive module 322, a second support frame 323, and a rotary drive module 324. The first support frame 321 is a fixed frame structure with a linear guide rail on it; the second support frame 323 is slidably connected to the linear guide rail via a slider and can move linearly along the first support frame 321.

[0041] A linear drive module 322 is mounted on a first support frame 321 and includes a first drive motor 3221, a lead screw 3222, and a nut slider 3223. The lead screw 3222 is positioned along the linear guide rail, with one end connected to the output shaft of the first drive motor 3221 and the other end rotatably connected to the first support frame 321 via a bearing seat. The nut slider 3223 is fitted onto the lead screw 3222 and fixedly connected to the second support frame 323. When the first drive motor 3221 operates, it drives the lead screw 3222 to rotate, which in turn causes the second support frame 323 to slide along the linear guide rail via the nut slider 3223.

[0042] The first support frame 321 has a clearance hole (not shown) in the middle. The rotary drive module 324 is mounted on the first support frame 321, and its output end passes through the clearance hole and is fixedly connected to the corner track frame 310. The rotary drive module 324 includes a second drive motor 3241, a transmission gear, and an output flange 3242. The second drive motor 3241 is fixed to the bottom of the first support frame 321, and its output shaft is connected to the transmission gear (exemplarily a bevel gear set to achieve 90-degree power steering). The output flange 3242 is fixedly connected to the driven wheel of the transmission gear, and its top surface is fixedly connected to the bottom of the corner track frame 310. By driving the transmission gear to rotate through the second drive motor 3241, the output flange 3242 and the corner track frame 310 are rotated, achieving 90-degree steering.

[0043] Example 4

[0044] Taking the transfer of materials from the first linear conveyor unit 100 to the second linear conveyor unit 200 as an example, the working process of this logistics transmission track is explained in detail:

[0045] 1. Initial state: The first active section 120 of the first straight conveying unit 100 is in the first position and docks with the fixed section 110; the corner reversing unit 300 is in the first docking state, and its corner track frame 310 is in the X direction under the drive of the rotary drive module 324 and docks with the fixed section 110 under the drive of the linear drive module 322.

[0046] 2. Material conveying to the corner reversing unit: The material (such as the conveying container 400) is conveyed from the fixed section 110 of the first straight conveying unit 100 to the corner track frame 310.

[0047] 3. Corner track frame steering adjustment: After the material has fully entered the corner track frame 310, the linear drive module 322 drives the second support frame 323 to move the corner track frame 310 away from the first movable section 120, so that it is disconnected from the fixed section 110; then the rotary drive module 324 drives the corner track frame 310 to rotate 90 degrees and switch to the Y direction (consistent with the direction of the second straight conveying unit 200).

[0048] 4. The corner track frame docks with the second straight conveyor unit: After the rotation is completed, the linear drive module 322 drives the second support frame 323 to move the corner track frame 310 toward the second straight conveyor unit 200, so that its output end docks with the input end of the second straight conveyor unit 200. At this time, the corner reversing unit 300 is in the second docking state.

[0049] 5. Material transfer to the second straight conveyor unit: The corner track frame 310 starts conveying and transfers the material to the second straight conveyor unit 200, completing one turning and transfer process.

[0050] If multi-height transfer is required, the height of the first movable section 120 or the second movable section 140 can be adjusted via the lifting drive assembly 130.

[0051] Example 5

[0052] This embodiment also provides a logistics conveying device, including a logistics conveying track as described in any one of embodiments 1-4 above and a conveying container 400. The conveying container 400 is slidably connected to the logistics conveying track, and its bottom is provided with guide wheels or sliders that match the track for stable operation on the track. The conveying container 400 can be designed with different sizes and structures according to the type of material, such as a box structure for loading packages or a rack structure for loading pallets.

[0053] It should be noted that the drive motor, transmission gears, lead screws and other components in this invention are all commercially available conventional products, and their specific models can be selected according to the requirements of conveying load, speed and other factors.

[0054] Based on this, this application achieves efficient reversing between tracks in different directions by using a segmented first straight conveying unit in conjunction with a switchable docking unit. The first straight conveying unit achieves rigid docking or precise disconnection between the moving and fixed sections through a lifting drive assembly. Combined with the state switching of the corner reversing unit between the two straight units, this effectively reduces the docking gap problem common in traditional reversing structures, avoids the risk of material deviation and derailment during transport, reduces impact vibration and noise, and ensures transportation safety. Furthermore, the lifting drive assembly occupies less space than a rotating mechanism. The segmented design and compact layout of the corner unit make the overall structure more suitable for space-constrained industrial workshops, warehouses, and other similar scenarios, eliminating the need for additional buffer space and expanding its applicability.

[0055] Obviously, the above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
