Abstract
Description
Technical Field
[0001] This invention relates to the field of shuttle racking technology, specifically to a guide rail type shuttle rack and its guide rail mechanism. Background Technology
[0002] Shuttle racking technology is one of the core technologies of automated high-density warehousing. Using racks as the carrier and shuttle vehicles as the execution unit, it is combined with a warehouse management system to achieve automated storage, retrieval, inventory, and relocation of goods. It eliminates the need for manual entry into the racking aisles, replacing traditional forklift aisle operations and significantly reducing aisle space occupation, increasing space utilization by 30%-50% compared to ordinary racking. This technology is adaptable to various warehousing environments, including normal temperature, low temperature, and high humidity, and is suitable for bulk goods storage in e-commerce, cold chain, and manufacturing industries. It can accurately control the rhythm of goods entering and leaving the warehouse, reducing labor costs and goods damage, while improving warehouse turnover efficiency. It is a key technological support for efficient flow in the supply chain warehousing process.
[0003] Based on the core logic of high-density storage using shuttle racking technology, guide rail shuttle racking is a specifically optimized sub-technology. Its key difference lies in the dedicated guide rails built into the racking aisles. The shuttle trolley runs precisely along the pre-set guide rails throughout its journey, offering significantly higher stability than ordinary shuttle racking. The guide rail design adapts to multi-level high-bay racking layouts, further freeing up vertical storage space. Furthermore, the shuttle trolley experiences less wear and tear, resulting in lower maintenance costs and quieter operation. It is suitable for scenarios with stringent requirements for storage and retrieval precision, such as those involving precision components and pharmaceutical consumables. It inherits the advantages of high-density storage while addressing the shortcomings in operational precision through guide rail optimization, thus meeting higher standards of warehousing needs.
[0004] However, in existing technologies, some goods are placed directly during warehousing and circulation without effective limiting constraints. During shuttle operation, lifting, or transfer, the goods are prone to deviation, shaking, or even tipping over, resulting in a high risk of damage. The stability and safety of the operation are insufficient, and the overall operational efficiency is limited, making it difficult to meet the operational requirements of automated warehousing that are unmanned, highly precise, and highly efficient. Summary of the Invention
[0005] The purpose of this invention is to provide a guide rail type shuttle rack and its guide rail mechanism.
[0006] The objective of this invention is achieved through the following technical solution: a guide rail shuttle rack, comprising multiple support frames for use in automated warehouses, with rails fixedly connected to the left and right side columns of each support frame, and shuttle cars arranged on adjacent sides of two rails, with multiple triggering components slidably connected to the inner wall of one of the rails, a top plate fixedly connected to the top of the support frame, a mechanical energy storage and reset motor fixedly connected to one end of the triggering components on the inner wall of the top plate, a turntable fixedly connected to the drive end of the mechanical energy storage and reset motor, multiple connecting rods rotatably connected to one side of the turntable, a mounting block rotatably connected to the other end of the connecting rods, a clamping plate fixedly connected to the outer wall of the mounting block, and a locking component inserted into the inner wall of one end of the connecting rod.

The rails are integrated rigid structures adapted to the load-bearing and guiding of the shuttle. The top surface of the rails is provided with guide tracks adapted to the rolling of the shuttle's wheels. The inner side wall of the rail body is provided with a limiting flange. The bottom of the rail body is provided with an integrated connecting base. The base is provided with an array of mounting holes for detachable connection with the support frame.
[0008] Compared with the prior art, the advantages of the present invention are as follows: 1. In this invention, after the goods are placed, the mechanical energy storage and reset motor is activated by the contact trigger component with the rail body and the magnetic contact conduction, which drives the turntable and connecting rod to move together.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1 to 8 The illustration shows an embodiment of a guide rail shuttle rack provided by the present invention, including multiple support frames 1 for use in automated warehouses. The support frames 1 provide a stable support foundation for the entire rack, adapting to the load-bearing requirements of automated warehouses and ensuring the overall structural stability of the rack. Rails 2 are fixedly connected to the left and right uprights of the multiple support frames 1. The rails 2 adopt an integrated rigid structure, cast from high-strength alloy material, effectively reducing the probability of deformation after long-term load-bearing, realizing the load-bearing support and guiding movement of the shuttle 3, and simultaneously providing a triggering component. The installation carrier includes a shuttle car 3 located on one side of each of the two rail bodies 2. The shuttle car 3 can lift the goods to be transported and complete the transfer operation with the guidance of the rail body 2, realizing the efficient movement of goods between the shelves and adapting to the needs of automated warehousing and transfer. The bottom sides of the shuttle car 3 are equipped with guide wheels that roll in cooperation with the rail body 2. The guide wheels are designed with wear-resistant rubber-coated hubs and roll in cooperation with the guide rollers of the rail body 2, improving the smoothness and wear resistance of the shuttle car 3 and ensuring that the shuttle car 3 moves stably without jamming. The contact surfaces of the guide wheels and the rail body 2 fit together properly.
[0013] Multiple trigger components are slidably connected to the inner wall of one of the rail bodies 2. These trigger components activate the circuit under the pressure of the cargo, providing a start signal to the mechanical energy storage and reset motor 11, thus enabling automatic start of the clamping mechanism without manual intervention and improving the automation level of the operation. The trigger components include a button 4 slidably connected to the inner wall of one of the rail bodies 2. The button 4 receives the pressure generated when the cargo is placed, driving the elastic column 6 to move synchronously, achieving the engagement and disengagement of magnet 7 and magnet 9, thereby controlling the circuit's on / off state. It is the core trigger component for the triggering action. Limit blocks 5 are fixedly connected to both the front and rear sides of the button 4. The limit blocks 5 prevent the button 4 from jamming or shifting laterally during movement, ensuring that the button 4 slides smoothly along the inner wall of the rail body 2, ensuring accurate and reliable triggering action. An elastic column 6 is fixedly connected to the bottom of the button 4, driving magnet 7 to move synchronously, and simultaneously triggering the action when the cargo leaves the rail body. 2. After the button 4 is reset, magnet 7 and magnet 9 are automatically separated, ensuring the circuit is disconnected in time. Magnet 7 is fixedly connected to the bottom of the elastic column 6. When magnet 7 and magnet 9 are in contact, they are electrically connected, providing power to start the mechanical energy storage reset motor 11. Compared with traditional contact switches, it has better wear resistance and conduction stability. Multiple cables 8 are also fixedly connected to the inner wall of one of the rails 2. Cables 8 are used to transmit circuit conduction signals, transmitting the power after magnet 7 and magnet 9 are connected to the mechanical energy storage reset motor 11, ensuring the motor starts in time and achieving stable circuit connection. One end of cable 8 is fixedly connected to magnet 9. Magnet 9 and magnet 7 work together to achieve circuit on / off control, providing a precise start signal for the mechanical energy storage reset motor 11, ensuring the reliability of trigger control. When magnet 7 and magnet 9 are in contact, they are electrically connected.
[0014] A top plate 10 is fixedly connected to the top of the support frame 1. The top plate 10 provides a mounting carrier for components such as the mechanical energy storage and reset motor 11, mounting block 15, and limit post 16, and also provides a sliding guide foundation for the limit post 16 to ensure stable operation of the clamping mechanism. The mechanical energy storage and reset motor 11, which is connected to one end of the trigger component, is fixedly connected to the inner wall of the top plate 10. When the mechanical energy storage and reset motor 11 is powered on, it drives the turntable 13 to rotate, thereby driving the clamping mechanism to clamp the goods and store mechanical energy. When the power is cut off, the mechanical energy is released and the turntable rotates in the opposite direction, automatically releasing the clamp and resetting. No additional power is required, solving the problem of continuous power supply to the motor and improving system reliability and energy efficiency. The other end of the cable 8 is electrically connected to the mechanical energy storage and reset motor 11. After the first magnet 7 and the second magnet 9 make contact and conduction, the mechanical energy storage reset motor 11 is powered and started through the cable 8. The drive end of the mechanical energy storage reset motor 11 is fixedly connected to the turntable 13. The turntable 13 rotates under the drive of the motor, which pulls the connecting rod 14 to move, providing a power transmission basis for the movement of the clamping plate 17. At the same time, it provides an adjustable rotation connection point for the connecting rod 14 to adapt to the clamping needs of different specifications of goods. The drive end of the mechanical energy storage reset motor 11 is fixedly connected to the fixing block 12. The fixing block 12 realizes the stable connection between the drive end of the mechanical energy storage reset motor 11 and the turntable 13, ensuring that the motor power is stably transmitted to the turntable 13 and ensuring that the turntable 13 rotates synchronously. The bottom of the turntable 13 is fixedly connected to the top of the fixing block 12.
[0015] Multiple connecting rods 14 are rotatably connected to one side of the turntable 13. The connecting rods 14 receive the rotational power of the turntable 13, driving the mounting block 15 and the clamping plate 17 to move, realizing the clamping and release of goods. At the same time, the connection point with the turntable 13 can be adjusted to change the travel of the clamping plate 17 to adapt to goods of different sizes. The other end of the connecting rod 14 is rotatably connected to the mounting block 15. The mounting block 15 provides the mounting base for the clamping plate 17 and the limiting post 16, receives the power transmitted by the connecting rod 14, and drives the clamping plate 17 to move synchronously, ensuring that the clamping plate 17 moves smoothly towards or away from the target. Two limiting posts 16 are fixedly connected to the side of the mounting block 15 near the top plate 10. The limiting posts 16 and the top plate 10 form a sliding fit to precisely limit the movement trajectory of the mounting block 15, ensuring that the clamping plate 17 moves smoothly in the preset direction and ensuring uniform clamping force. The outer side of the limiting posts 16 is slidably connected to the inner wall of the top plate 10, and the outer side of the mounting block 15 is fixedly connected to the clamping plate 17. The clamping plate 17 moves towards the cargo to achieve stable clamping of the cargo, preventing the cargo from shifting or tipping over during storage and ensuring the safety of cargo storage.
[0016] A locking component is inserted into the inner wall of one end of the connecting rod 14. This locking component locks the connection point between the connecting rod 14 and the turntable 13, ensuring the stability of the adjusted connecting rod 14 and preventing displacement during clamping, thus improving clamping reliability. It also facilitates adjustment of the clamping distance. The locking component includes a post 18 inserted into the inner wall of one end of the connecting rod 14. The post 18 can be fitted and engaged with a slot in the turntable 13 to lock the position of the connecting rod 14. The locking is released when the post disengages from the slot, facilitating adjustment of the connection point of the connecting rod 14. Along with the core component for unlocking, the turntable 13 has multiple sliding grooves on one side. These grooves provide sliding channels for the insert post 18, facilitating the movement of the connecting rod 14 along the grooves to adjust the connection points. This ensures smooth adjustment operations and adapts to the clamping distance requirements of goods of different sizes. The inner wall of the grooves has multiple slots that fit and engage with the insert post 18, providing multiple lockable connection points for the connecting rod 14. This allows for multi-level adjustment of the clamping distance, improving the shelf's adaptability to goods of different sizes. The insert post 18 is externally slidably connected to the groove. The inner wall of the plate 10 has a locking mechanism. One end of the insertion post 18 can be fitted and engaged with multiple slots on the inner wall of the turntable 13. The other end of the insertion post 18 is fixedly connected to a button 19, which allows for manual pulling of the insertion post 18 to disengage and reposition it from the slots. The operation is simple and convenient, and the clamping distance can be adjusted without special tools. A washer 20 is rotatably connected to the outside of the insertion post 18. The washer 20 supports the elastic force of the spring 21 and abuts against the inner wall of the top plate 10, providing a force base for the spring 21 and ensuring that the spring 21 pushes the insertion post 18. The stud 18 is stably reset, improving the operational stability of the locking assembly. The outer side of the gasket 20 is slidably connected to the inner wall of the top plate 10. The outer side of the stud 18 is fitted with a spring 21. The spring 21 is made of corrosion-resistant steel, which can improve the elastic recovery ability after long-term use, release elastic potential energy to push the stud 18 to reset and lock, realize the stable locking of the connecting rod 14, and extend the service life of the locking assembly. One end of the spring 21 is fixedly connected to one side of the button 19, and the other end of the spring 21 is fixedly connected to one side of the gasket 20.
[0017] A guide rail mechanism for shuttle racks, applied to the aforementioned guide rail type shuttle rack, includes two symmetrically parallel rail bodies 2. Each rail body 2 is an integrated rigid structure adapted to the load-bearing and guiding function of a shuttle 3, ensuring stable movement of the shuttle 3 and providing support for goods placement. It triggers the action of a triggering component. The top surface of the rail body has a guide roller track adapted to the rolling of the shuttle 3's wheels. The guide roller track undergoes high-frequency quenching treatment and rolls in conjunction with the guide wheels of the shuttle 3, improving guiding accuracy and wear resistance, ensuring smooth and non-deviationist movement of the shuttle 3. The inner wall of the rail body is provided with… The limiting flange prevents the shuttle 3 from deviating during operation, ensuring that the shuttle 3 travels along the preset track of the rail body 2 and improving the stability of the transfer operation. The bottom of the track body is provided with an integrated connecting base, which provides a foundation for the connection between the rail body 2 and the support frame 1, ensuring the stable assembly of the rail body 2 and improving the overall structural stability of the rack. The base is provided with an array of mounting holes, which enable the detachable connection between the rail body 2 and the support frame 1. This facilitates the later maintenance and replacement of the rail body 2 and improves the economic efficiency of the rack.
[0018] Working principle: The track body 2 adopts an integrated rigid structure and is cast from high-strength alloy material, which effectively reduces the probability of deformation after long-term load. The guide raceway on its top surface is treated with high-frequency quenching. Together with the guide wheel at the bottom of the shuttle car 3, which adopts a wear-resistant rubber-coated hub design to improve rolling smoothness and wear resistance, the shuttle car 3 can move stably. The limiting flange on the inner side wall of the track body 2 can prevent the shuttle car 3 from deviating during operation. The bottom connecting base is detachably assembled with the support frame 1 through an array of mounting holes, which is convenient for later maintenance and replacement.
[0019] During operation, the shuttle car 3 first lifts the goods to be transported, and completes the transfer operation with the guidance of the rail body 2. When the goods are transported to the target position, the shuttle car 3 releases the goods and places them stably. At this time, the goods are in close contact with the rail body 2 and generate pressure. This pressure acts on the button 4 of the trigger component. Under the limiting and guiding action of the limit block 5, the button 4 drives the elastic column 6 to move synchronously, thereby pushing the magnet 7 to approach and adhere to the magnet 9. After the two come into contact, electrical conduction is achieved. The cable 8 transmits the conduction signal to the mechanical energy storage reset motor 11 inside the top plate 10, and starts the mechanical energy storage reset motor 11 to run. The fixed block 12 installed at the drive end of the mechanical energy storage reset motor 11 drives the turntable 13 to rotate synchronously. When the turntable 13 rotates, it pulls the connecting rod 14 to move. Since the limiting post 16 installed on the mounting block 15 forms a sliding fit with the top plate 10, the movement trajectory of the mounting block 15 can be precisely limited, so that the connecting rod 14 drives the mounting block 15 and the clamping plate 17 to move synchronously towards the cargo, ultimately achieving stable clamping of the cargo and preventing the cargo from shifting or tipping over during storage.
[0020] For goods of different sizes, the rack can adjust the clamping distance through the locking component to improve adaptability: Pulling button 19 moves the insert 18, the insert 18 disengages from the slot in the inner wall of turntable 13, and releases the locking restriction on connecting rod 14. At this time, connecting rod 14 can be pushed to move along the slide of turntable 13, adjusting the position of the rotation connection point between connecting rod 14 and turntable 13. The closer the rotation connection point is to the center of turntable 13, the shorter the travel of connecting rod 14 driving mounting block 15 and clamping plate 17, thus adapting to larger goods.
[0021] After adjustment, release button 19. The spring 21, fitted around the plug 18, releases its elastic potential energy, pushing the pad 20 against the inner wall of the top plate 10. Simultaneously, the plug 18 resets and engages with the corresponding slot on the turntable 13, locking the position of the connecting rod 14 and ensuring its stability during clamping, thus guaranteeing clamping reliability. The limit block 5 prevents jamming during the movement of the button 4. The contact conduction design of magnet 7 and magnet 9 provides better wear resistance and conduction stability compared to traditional contact switches. The spring 21, made of corrosion-resistant steel, enhances its elastic recovery capability after long-term use, extending the service life of the locking components.
[0022] When goods need to be removed, the lifting mechanism of shuttle 3 starts to lift the goods. During the lifting process, the goods detach from the rail 2, and the button 4 resets under the action of its own elastic column 6, causing the elastic column 6 and magnet 7 to rise. Magnet 7 separates from magnet 9, and the circuit remains open. At this time, the mechanical energy storage reset motor 11 releases the internal mechanical energy due to power failure, driving the output shaft to rotate in the opposite direction by the same number of revolutions (consistent with the number of revolutions in the forward direction), driving the turntable 13 to rotate in the opposite direction, and then pulling the mounting block 15 and the clamping plate 17 to move in the opposite direction through the connecting rod 14, automatically releasing the clamp on the goods and realizing the mechanism reset. Among them, the limit block 5 can prevent the button 4 from shifting laterally during movement. The contact and conduction design of magnet 1 7 and magnet 2 9 has better wear resistance and conduction stability compared with traditional contact switches. The spring 21 is made of corrosion-resistant steel, which can improve the elastic recovery ability after long-term use and extend the service life of the locking component. The mechanical energy storage reset motor 11 can complete the reset action without additional power, which not only solves the problem of continuous power supply of the motor, but also realizes the automatic release of the clamping mechanism, improving the reliability and energy saving of the system operation.
