Description

Technical Field

[0001] This utility model relates to the field of transportation, and more specifically, to an automated loading and unloading terminal equipment. Background Technology

[0002] In modern logistics warehousing and manufacturing, material frames (such as metal racks and logistics boxes) serve as standard units for carrying goods. Their efficient and safe loading, unloading, and transfer are crucial for improving overall logistics efficiency, especially in scenarios such as internal factory logistics and the handover points (docks) between warehouses and transport vehicles. Currently, the loading and unloading operations involving material frames, particularly the transfer between trucks and fixed conveyor lines, and the directional adjustment of material frames during transport, mainly suffer from the following problems and shortcomings:

[0003] High dependence on manual labor and low efficiency: In many situations, loading and unloading of material crates still relies on manual labor or traditional forklifts. Manual handling is labor-intensive, inefficient, and slow, becoming a bottleneck in logistics. Although forklift operations can improve efficiency to some extent, they require operators and are subject to problems such as waiting, scheduling, and limited operating space. Efficiency is difficult to further improve during peak hours or in space-constrained dock areas.

[0004] Low automation and fragmented processes: While some automated conveying equipment exists (such as roller conveyors and chain conveyors), it often only enables horizontal conveying in a single direction. When it's necessary to remove material frames from truck beds and transfer them to fixed conveyor lines, or to change the orientation of the frames during transport (e.g., rotating them 90 degrees to connect with production lines or warehouse aisles in different directions), there is a lack of effective, integrated automation solutions. Typically, multiple independent devices (such as forklifts, transfer machines, and turntables) are required for segmented operation. The connections between these devices are not smooth, requiring manual intervention or complex scheduling, leading to process interruptions, long waiting times, and overall low efficiency.

[0005] Handling heavy-duty crates presents challenges and safety hazards: Moving large or fully loaded heavy-duty crates manually is difficult and dangerous, easily causing muscle injuries or crushing accidents. Even when using forklifts, there is a risk of collision in confined spaces or during frequent loading and unloading. Existing simple handling devices often lack stable and reliable lifting and lateral movement capabilities, making it difficult to handle heavy-duty crates safely and efficiently.

[0006] Insufficient space utilization and adaptability: Traditional loading and unloading methods (such as forklifts) require a large operating space. Dock areas typically have limited space, and existing equipment may not adequately accommodate the loading and unloading needs of truck beds of varying heights, material crates of different sizes, and the docking requirements with conveyor lines in different directions. There is a lack of compact, flexible equipment capable of automatically adjusting the position and orientation of material crates.

[0007] Unable to achieve continuous flow operations: Due to the aforementioned issues of process fragmentation and low automation, it is difficult to achieve seamless and continuous flow of material boxes from trucks to internal conveyor lines and then to designated locations (such as production lines and storage areas), which hinders the realization of lean logistics and automated logistics systems.

[0008] Therefore, there is an urgent need for a highly automated and integrated terminal loading and unloading equipment that can automatically complete the entire process of taking the material frame out of the truck bed, smoothly transferring it to a fixed conveyor line, adjusting its direction as needed during the transportation process, and finally delivering it to the target location. This would significantly improve loading and unloading efficiency, reduce labor intensity, ensure operational safety, optimize space utilization, and achieve continuous logistics. Utility Model Content

[0009] Based on this, in order to solve the problems of low automation, difficulty in handling heavy material crates, high labor intensity, prominent safety hazards, and insufficient space utilization and adaptability of traditional transportation equipment, this utility model provides an automatic loading and unloading dock equipment, the specific technical solution of which is as follows:

[0011] The aforementioned automated loading and unloading terminal equipment can automatically complete the entire process of removing the material frame from the truck bed, horizontally transferring it, adjusting its direction (rotating it), and finally delivering it to the target location (such as an internal conveyor line, warehouse, or production line).

Both the lifting and shifting device and the lifting chain conveyor have lifting functions, enabling them to reliably insert the moving end of the device into the bottom of the material frame and safely lift it, completely avoiding the risks associated with manual handling or traditional forklift operation of heavy material frames. The rotary conveyor can precisely adjust the direction of the material frame (e.g., rotating it 90 degrees) to accurately align it with the next process (e.g., roller conveyor lines or warehouse aisles in different directions), solving the problems of single-direction and difficult docking in traditional conveyor lines, and improving the adaptability of the equipment and the flexibility of site layout. The compact equipment design reduces the operating space required for large equipment such as forklifts, making it particularly suitable for space-constrained terminal areas.

[0032] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0033] like Figures 1-3As shown, an automatic loading and unloading dock equipment according to one embodiment of the present invention includes a lifting and shifting device 1, a chain conveyor 2, a lifting chain conveyor 32, a rotary conveyor 4, and a roller conveyor 5 connected in sequence. The moving end of the lifting and shifting device 1 is used to move to the bottom of the material frame and lift the material frame, and drive the material frame to the truck 10 or the chain conveyor 2. The chain conveyor 2 is used to drive the material frame to the moving end of the lifting and shifting device or the lifting chain conveyor 32. The moving end of the lifting chain conveyor is used to move to the bottom of the material frame and lift the material frame, and drive the material frame to the chain conveyor 2 or the rotary conveyor 4. The rotary conveyor 4 is used to drive the material frame to rotate and align it with the roller conveyor 5 or the lifting chain conveyor 32.

[0034] The aforementioned automated loading and unloading terminal equipment can automatically complete the entire process of removing the material frame from the truck bed 10, horizontally transferring it, adjusting its direction (rotating it), and finally delivering it to the target location (such as an internal conveyor line, warehouse, or production line). The various devices are closely connected (such as lifting and shifting → chain conveyor → lifting chain conveyor → rotary conveyor → roller conveyor), eliminating manual intervention and waiting time between devices, forming a continuous flow operation mode, significantly reducing loading and unloading time, and improving the overall throughput capacity of the terminal, especially suitable for high-frequency, large-volume loading and unloading scenarios. Both the lifting and shifting device 1 and the lifting chain conveyor device 3 have lifting functions, which can stably and reliably insert the moving end of the device into the bottom of the material frame and safely lift it up, completely avoiding the risks of manual handling or traditional forklift operation of heavy material frames. The rotary conveyor device 4 can accurately adjust the direction of the material frame (such as rotating it 90 degrees) to accurately align it with the next process (such as roller conveyor lines or warehouse passages in different directions), solving the problem of single direction and difficult docking of traditional conveyor lines, and improving the adaptability of the equipment and the flexibility of site layout. The compact equipment design reduces the operating space required for large equipment such as forklifts, making it particularly suitable for terminal areas with limited space.

[0035] like Figures 1-3As shown, in one embodiment, the lifting and translating device 1 includes a base 11, a first guide assembly 12, a lifting drive assembly 13, and a lifting and moving assembly 14; one end of the first guide assembly 12 is connected to the base 11, and the other end of the first guide assembly 12 is connected to the lifting and moving assembly 14; the lifting drive assembly 13 is disposed on the base 11, and the output end of the lifting drive assembly 13 is connected to the lifting and moving assembly 14; the lifting drive assembly 13 is used to drive the lifting and moving assembly 14 to move up and down; the lifting and moving assembly 14 is used to move to the bottom of the material frame and lift the material frame, and drive the material frame to move onto the truck 10 or the chain conveyor 2; the first guide assembly 12 includes a first guide block and a first guide cylinder, the first guide cylinder is sleeved on the first guide block and slidably connected to the first guide block; the first guide block is vertically disposed on the base 11, and the first guide cylinder is connected to the lifting and moving assembly 14; the lifting drive assembly 13 includes a first moving block 131, a first moving block 132, a first moving block 13 ... The system includes a roller 132, a second roller 133, and a first cylinder 134. The first roller 132 is mounted on the base 11, and the second roller 133 is mounted on the bottom of the lifting and moving assembly 14. The first cylinder 134 is mounted on the base 11 and connected to the first moving block 131. The first moving block 131 has a first inclined surface 6. The first roller 132 and the second roller 133 cooperate to clamp the first moving block 131. The second roller 133 moves along the first inclined surface 6. The first cylinder 134 is used to drive the first moving block 131 to reciprocate; the lifting and moving assembly 14 includes a lifting base 141, a first driving block 142, a third roller 143, a translation plate 145 and a fourth roller 146; the first guide cylinder is connected to the lifting base 141; the first driving block 142 is disposed on the lifting base 141, the output end of the first driving block 142 is connected to the third roller 143, and the first driving block 142 is used to drive the third roller 143 to rotate. Thus, by adopting a sliding structure of the first guide block and the first guide cylinder (the first guide cylinder is sleeved on the first guide block), a vertical guide system with high rigidity and high guiding accuracy is formed; the lifting drive assembly 13 innovatively adopts a first cylinder 134 to drive the first moving block 131 with the first inclined surface 6, and utilizes the structure of the first roller 132 and the second roller 133 to clamp the first moving block 131. The horizontal reciprocating motion of the cylinder, through the contact between the first inclined surface 6 and the second roller 133, efficiently and reliably converts the horizontal thrust into the vertical lifting motion of the lifting moving assembly 14 (the second roller 133 moves along the first inclined surface 6);

[0036] like Figures 1-5As shown, in one embodiment, the translation plate 145 is mounted on and slidably connected to the third roller 143; the fourth roller 146 is mounted on the lifting base 141, and the fourth roller 146 cooperates with the third roller 143 to clamp the translation plate 145. Thus, the translation plate 145 is directly mounted on the third roller 143 and slidably connected to achieve movement; the fourth roller 146 is mounted on the lifting base 141 and cooperates with the third roller 143 that carries the translation plate 145 to jointly "clamp" the translation plate 145. This design of the two rollers (third and fourth rollers 146) working together provides precise lateral constraint and guidance for the movement of the translation plate 145, effectively preventing lateral displacement, swaying, or tilting of the translation plate 145 during movement. Especially when carrying heavy or irregular material frames, it ensures the stability of the translation process and the straightness of the trajectory, guaranteeing the positioning accuracy of the material frame and the safety of equipment operation.

[0037] like Figures 1-5 As shown, in one embodiment, the lifting chain conveyor 3 includes a first chain conveyor 31, a second moving block 32, a fifth roller 33, a sixth roller 34, a second cylinder 35, and a second guide assembly 36; the second guide assembly 36 is arranged vertically and connected to the first chain conveyor 31; the fifth roller 33 is located at the bottom of the first chain conveyor 31; the second moving block 32 is provided with a second inclined surface 7; the fifth roller 33 and the sixth roller 34 cooperate to clamp the second moving block 32; the second cylinder 35 moves with the second moving block 32; and the second cylinder 35 is used to drive the second moving block 32 to reciprocate.

[0038] like Figures 1-5As shown, in one embodiment, the rotary conveying device 4 includes a second chain conveying device 41, a fixed sleeve 42, a rotating shaft 43, a bearing 44, and a slide rail 45; the outer contour of the slide rail 45 is arc-shaped, the fixed sleeve 42 is vertically oriented, the bearing 44 is disposed inside the fixed sleeve 42, one end of the rotating shaft 43 is connected to the second chain conveying device 41, and the other end of the rotating shaft 43 is inserted into the inner ring of the bearing 44; a seventh roller 8 is provided at the bottom of the second chain conveying device 41, and a drive motor 9 is provided on the seventh roller 8, the drive motor 9 being used to drive the seventh roller 8 to rotate; the seventh roller 8 is slidably connected to the slide rail 45. Thus, by adopting a structure in which a bearing 44 is installed inside a fixed sleeve 42, one end of the rotating shaft 43 is inserted into the inner ring of the bearing 44 and connected to the second chain conveying mechanism, providing a rigid, low-friction central rotation support, effectively bearing axial loads and ensuring the stability of the rotation axis; through the arc-shaped slide rail 45 and the sliding connection of the seventh roller 8 on the slide rail 45, it is easy to align the material frame with the roller conveying device 5.

[0039] Working principle:

[0040] Loading process: The material frame of the workshop production line is conveyed to the rotary conveyor 4 by the roller conveyor 5. The rotary conveyor 4 rotates to make the direction of the material frame consistent with the direction of the truck 10. The material frame is then conveyed to the lifting and translating device 1 by the chain conveyor 2. The translating plate 145 on the lifting and translating device 1 lifts the material frame and translates it onto the truck 10. The translating plate 145 on the lifting and translating device 1 then descends and retracts, realizing the loading action.

[0041] Unloading process: The truck 10 stops at the unloading position, the lifting and shifting device 1 extends the shifting plate 145, the shifting plate 145 lifts the material frame and shifts the material frame onto the chain conveyor device 2, the chain conveyor device 2 transfers the material frame to the rotary conveyor device 4, the rotary conveyor device 4 rotates to make the direction of the material frame consistent with the direction of the roller conveyor device 5, the roller conveyor device 5 delivers the material frame to the workshop production line, realizing the unloading action.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
