Description

Technical Field

[0001] The present invention relates to the technical field of warehouse transportation, and in particular to a warehouse transportation structure with a guide rail shuttle rack. Background Art

[0002] Warehouse transportation is a key link between warehouse management and logistics distribution. It achieves efficient material flow by planning the flow path of goods from the storage area to the destination. Its operations cover processes such as cargo sorting, loading, transportation route optimization, and unloading and warehousing. It is necessary to select appropriate transportation tools such as forklifts, pallet trucks, and vans based on the characteristics of the goods, such as weight, size, and shelf life. The location and transportation status of goods are tracked in real time with the help of the WMS warehouse management system. Modern warehouse transportation introduces intelligent scheduling algorithms, combined with GPS positioning and Internet of Things technology, to reduce empty driving rates and shorten delivery time. At the same time, standardized loading and unloading processes are used to reduce cargo loss. It is a core link in supply chain management to ensure inventory turnover and logistics timeliness.

[0003] Rail-type shuttle racking is the core equipment of high-density warehousing systems, consisting of the rack itself, shuttle vehicles, and rails. The shuttle vehicles operate along fixed rails within the racks, accessing and moving goods through automated control. They can replace traditional forklifts entering aisles, addressing the space constraints of narrow aisles. Their storage density is over 30% higher than traditional racking, making them suitable for industries with demanding storage environments, such as food and pharmaceuticals. The system supports both first-in-first-out (FIFO) and last-in-last-out (LIFO) modes, and integrates with the WMS warehouse management system for intelligent scheduling. With advantages such as high access efficiency, maximum space utilization, and low labor costs, the shuttle vehicles are a key solution for improving storage efficiency in modern intelligent warehousing.

[0004] In the prior art, there is a guide rail shuttle rack with application number 202322931945.2, and its technical solution is: it includes a bottom plate, both sides of the top of the bottom plate are fixedly connected to support blocks, the upper end of the bottom plate is provided with an adjustment component, the upper end of the bottom plate is provided with a lifting component, the adjustment component includes two fixed plates, one end of the two fixed plates is fixedly connected to one of the support blocks, one end of one of the support blocks is fixedly connected to a bracket, one end of the bracket is fixedly connected to a motor, the output end of the motor passes through one of the fixed plates and is fixedly connected to a bidirectional screw rod, and the two ends of the bidirectional screw rod are respectively rotatably connected to one end of the opposite surfaces of the two fixed plates.

[0005] In the prior art, for example, there is a rail shuttle rack with application number 202222888674.2, whose technical solution is as follows: including a support structure, rails, a shuttle, and a pallet. The rails are fixedly mounted on the support structure, a reflector is mounted on the front end of the rails, and pallet adjustment plates are mounted on both sides of the rails. The rails are provided with a shuttle support portion and a pallet support portion, the shuttle is placed on the shuttle support portion, rollers are mounted on the pallet support portion, and the pallet is placed on the pallet support portion. The pallet is provided with arc-shaped anti-collision portions on the front and rear sides, and a docking groove is provided under the pallet, which cooperates with the pushing device on the shuttle.

[0006] In the field of modern warehousing and logistics, the existing rail-type shuttle racking system has significant technical bottlenecks. Traditional racks rely on manual or fixed rules to store goods and cannot automatically classify goods according to weight. An unreasonable layout often occurs, where heavy goods are placed on the upper shelves and light goods occupy the lower shelves. This not only increases the risk of shelf load, but also requires frequent adjustments to the cargo position when picking up goods, reducing operational efficiency. In addition, the shuttle machine's docking mechanism with the conveyor line or forklift during transportation mostly adopts rigid positioning. When faced with the impact of goods of different weights, it is prone to shaking, offset and other problems. Especially in high-speed storage and retrieval scenarios, unstable docking can lead to goods tipping, equipment wear, and even safety accidents, making it difficult to meet the requirements of automated warehousing for accuracy and reliability.

[0007] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case.

[0008] In response to the above problems, an innovative design was carried out based on the original rail shuttle rack. Summary of the Invention

[0012] Preferably, a first servo motor is fixedly installed on the front side of the baffle box, and a rotating shaft is connected to the output end of the rear side of the first servo motor, and a first bevel gear is fixedly installed on the front and rear sides of the rotating shaft.

[0013] With the above technical solution, the first servo motor drives the first bevel gear to rotate through the rotating shaft, providing power for the lateral movement of the shuttle platform. The moving speed and position of the shuttle platform on the guide rail groove can be accurately controlled to ensure the accuracy of the cargo transportation path.

[0014] Preferably, the left side of the first bevel gear is meshed with a second bevel gear, and the left end of the second bevel gear is connected to a first threaded rod, the first threaded rod is rotatably connected to the left side of the guide rail groove, and the threads of the front and rear first threaded rods rotate in opposite directions.

[0015] With the above technical solution, the first bevel gear and the second bevel gear engage to drive the first threaded rod to rotate, so that the slider drives the shuttle to move smoothly left and right, avoiding shaking during transportation.

[0016] Preferably, the exterior of the first threaded rod is threadedly connected to a slider, and the slider is slidably connected to the top of the guide rail groove, and the slider is fixedly installed on the front and rear sides of the right side of the shuttle platform.

[0017] With the above technical solution, the slider is threadedly connected to the first threaded rod and slides on the guide groove, converting the rotational motion of the threaded rod into the linear motion of the shuttle, thereby ensuring the stability and positioning accuracy of the shuttle movement.

Limiting slots are provided on both sides of the limiting plates, and the connecting rod passes through the limiting slots, and the horizontal movement of the limiting block drives the lifting platform to form a lifting structure.

[0021] With the above technical solution, the connecting rod passes through the limit slot, and the horizontal movement of the limit block drives the lifting platform to move up and down.

Heavy goods are stored in a lower position as much as possible to meet the cargo handling needs of multi-layer shelves.

[0024] Preferably, a sliding rod is fixedly installed between the bottom of the support frame at the left rear side of the second shelf and the support frame at the left rear side of the first shelf, and the lifting platform passes through the sliding rod to form a lifting limit structure, and guardrails are fixedly installed on the left side and front and rear sides of the lifting platform.

[0029] By adopting the above technical solution, the second moving block moves and drives the ejection block to be ejected through the connecting rod, thereby realizing automatic unloading of goods and improving the efficiency and automation of cargo loading and unloading.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the warehouse transportation structure with rail-type shuttle racks,

[0031] 1. Intelligent weight-based storage of goods optimizes shelf load distribution: A pressure sensor on the edge of the first shelf detects the weight of the goods in real time. The controller automatically plans the storage location based on the weight data. Heavy goods are transported to the first shelf on the bottom floor by a shuttle platform, while light goods are transported to the second shelf on the upper floor. This classified storage mechanism avoids the irrational layout of traditional shelves where heavy goods are placed on the upper shelves and light goods occupy the lower shelves. It improves the overall load uniformity of the shelves and significantly reduces the risk of deformation of high-rise shelves due to overloading. At the same time, heavy goods stored on the bottom floor are convenient for direct loading and unloading by forklifts, while light goods on the upper floors are stored and retrieved through a shuttle platform and a lifting platform. This creates an efficient operation process where heavy goods are placed on the ground and light goods are placed on the shelves, thereby improving warehouse operation efficiency.

[0032] 2. The dual-track driven shuttle platform and limited lifting structure ensure transportation stability: The shuttle platform is slidably connected to the guide rail grooves through the front and rear sliders. The first servo motor drives the first threaded rod to rotate, achieving smooth movement of the shuttle platform in the front and rear directions of the shelf. The movement accuracy reaches ±5mm, preventing the goods from tipping over due to shaking during transportation. The first pneumatic telescopic rod drives the first moving block, which drives the connecting rod and the limit block to move, providing power for the lifting platform to move and support the goods until they are placed on the outer side of the shelf for storage.

[0033] 3. Improve the stability of cargo lifting and docking: When the lifting platform is lifted and lowered along the sliding rod, it is powered by the second servo motor and the second threaded rod. The limiting function of the sliding rod reduces the vertical movement error of the lifting platform, and the guardrail is used to prevent cargo from falling. When the shuttle platform is docked with the lifting platform, the second pneumatic telescopic machine pushes the second moving block to slide in the lifting platform, providing power for the ejection action of the ejection block, making it easier to transfer cargo from the lifting platform to the shuttle platform for continued transportation. Compared with the traditional rigid docking mechanism, the reduced shaking ensures transportation safety in high-speed storage and retrieval scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
