Description

Technical Field

[0001] This invention relates to the field of warehouse racking technology, specifically to a shuttle-type multifunctional intelligent warehouse racking system. Background Technology

[0002] Storage racks are three-dimensional storage devices used in warehousing systems to carry and store unitized goods. The core of them is to significantly increase storage density by utilizing the vertical space of the warehouse, so as to achieve the classification, orderly management and rapid access of goods. From traditional shelving, beam racks and cantilever racks to shuttle racks, gravity racks and three-dimensional racks with integrated intelligent picking mechanisms that are adapted to automated operations, they are widely used in the warehousing links of manufacturing, logistics, e-commerce, retail and other industries, and are an indispensable infrastructure in the modern warehousing and logistics system.

[0003] Refer to the relevant patent CN113501244B, which features a fixed-point airflow jet device controlled by an air pump and a partitioned solenoid valve on the side of the guide rail vertical plate. This, combined with the guide rail cleaning holes that can be lifted and opened by an electric cylinder and the partitioned independently driven mechanical pushing and sweeping mechanism, forms a three-stage progressive cleaning process of "airflow blowing - gravity dropping - mechanical pushing and removing". This can remotely and automatically remove debris from the guide rail horizontal plate that causes the shuttle transport plate to jam, eliminating the need for manual climbing and significantly improving the intelligence level and maintenance convenience of the rack operation.

[0004] In existing technologies, intelligent warehouse shuttle racking typically uses a cubic frame structure with equal height and width, and the shuttle can only move back and forth on the horizontal guide rails of a single height level. This approach has the following significant inconveniences: First, the center of gravity of the racking is relatively high. To ensure stability, goods must be stacked according to a strict principle of centering the heaviest items, resulting in low utilization of upper-level space and poor overall anti-tipping ability. Second, each guide rail level requires an independent shuttle or a complex lifting mechanism, which results in high equipment costs and fixed paths. It is impossible for a single device to flexibly cover multiple layers and multiple rows of storage locations. During outbound operations, multiple layer changes or reloading are required, leading to low storage and retrieval efficiency.

[0005] Therefore, a right-angled trapezoidal structure that is wider at the bottom and narrower at the top should be adopted, following the principle of being heavier at the bottom and lighter at the top, to lower the center of gravity and enhance overall stability. In addition, inclined and horizontal tracks connecting multiple layers should be set up, along with directional baffles, so that a single device can cover the entire storage and retrieval area. To this end, we provide a shuttle-type multi-functional intelligent warehouse rack to solve the above problems. Summary of the Invention

[0034] The present invention will be further described in detail below with reference to embodiments:

[0035] Example 1: As Figure 1-10 As shown, the present invention provides a shuttle-type multi-functional intelligent storage rack, including a base 1. The top surface of the base 1 is provided with rack units 2 distributed in a right-angled trapezoidal shape with a wider bottom and a narrower top and equipped with an inclined track design. The sides of the rack units 2 are provided with retrieval units 3 that can shuttle through different storage areas inside the rack units 2 and retrieve target goods. The rack unit 2 includes a rack support 21 fixedly installed on the top surface of the base 1, a bracket 22 set inside the rack support 21 for placing goods, a partition 23 set on the bottom surface of the bracket 22 for easy retrieval, and a retrieval track 24 set on the side of the rack support 21 for retrieving goods.

[0036] The overall frame of the shelving support 21 is a right-angled trapezoid, with its storage capacity decreasing layer by layer from bottom to top. It also follows the principle of distributing goods with heavier loads at the bottom and lighter loads at the top, lowering the center of gravity and enhancing overall anti-tipping stability. One side of the frame is open, and with the support of the raised frame 210, the bottom surface forms a cavity that allows the movable picking seat 39 and the top plate 310 to enter and exit, reserving space for bottom-loading operations.

[0037] The rack support 21 has a bracket plate 211 inside, which is adapted to the bottom structure of the bracket 22. The bottom surface of the bracket 22 has a locking rod 214, which can be locked into the locking groove 212 opened on the bracket plate 211. By locking, the longitudinal and lateral degrees of freedom of the bracket 22 are constrained, ensuring its static stability in the storage position. The bottom surface of the bracket 22 also has a material picking positioning groove 216 and a limiting groove 215, which are used to form a reliable positioning cooperation with the material picking device during handling and loading, preventing the bracket from moving or tilting during transfer, thereby ensuring the stability of the conveying process.

[0038] Multiple movable pads 25 are fixedly connected to the top surface of the partition 23. A baffle 27 is fixedly connected to the side of the material picking track 24. A guide bracket 26 is provided on the top surface of the material picking track 24. The guide bracket 26 is fixedly connected to the side of the partition 23. A directional baffle 29 is movably connected to the side of the guide bracket 26. A drive motor is fixedly connected to the side of the guide bracket 26. The directional baffle 29 is located at the output end of the drive motor. A rack 28 is fixedly connected inside the material picking track 24.

[0039] The partition 23 contains movable pads 25 corresponding to the number of layers in the shelf support 21. The top surface of the movable pads 25 is covered with an auxiliary pad layer adapted to the traveling wheels 319 to reduce rolling resistance and provide a guiding foundation for the traveling wheels. The sides of the movable pads 25 are fixedly connected to the picking track 24 and the guide bracket 26, which together form an auxiliary frame that provides multi-directional control over the movement trajectory of the displacement carriage 37. This auxiliary frame contains multiple sets of parallel horizontal tracks, connected to different height layers via an inclined track, forming a continuously reversible travel path. Both the picking track 24 and the guide bracket 26 have baffles 27 fixed to their sides to define the track boundaries. At the turning points of the guide bracket 26, a directional baffle 29 driven by a power structure is installed. This baffle is limited by the baffle 27 and can only switch positions between the inclined track entrance and the corresponding horizontal track opening, changing the travel direction of the displacement carriage 37 like a mechanical switch, thereby completing the path conversion between inter-layer lifting and intra-layer lateral movement.

[0040] The bottom surface of the shelf support 21 is fixedly connected to a raised frame 210. The inside of the shelf support 21 is fixedly connected to two opposing bracket plates 211. The inside of the bracket plate 211 is provided with a slot 212. The top surface of the bracket 22 is fixedly connected to a railing 213. The bottom surface of the bracket 22 is provided with a material picking and positioning slot 216. The middle part of the bracket 22 is provided with a limit slot 215. The bottom surface of the bracket 22 is fixedly connected to a locking rod 214, which is engaged inside the slot 212. The inside of the side of the material picking plate 32 is provided with a sliding groove. The sliding groove inside the material picking plate 32 is slidably connected to a steering plate 36. The bottom surface of the material picking plate 32 is fixedly connected to a hydraulic telescopic rod 35. The steering plate 36 is fixedly connected to the output end of the hydraulic telescopic rod 35.

[0041] In this embodiment, the storage rack, composed of multiple modular rack supports 21, forms a right-angled trapezoidal outline. The storage space decreases progressively from bottom to top, and the goods are arranged strictly according to the principle of heavier loads at the bottom and lighter loads at the top, in order to optimize structural stress and reduce the risk of tipping over. The picking rail 24 and guide bracket 26, fixedly connected to the side of the rack, provide a motion auxiliary frame for the picking base 34, integrating lifting and lateral movement, allowing one picking device to cover multiple layers and multiple rows of storage positions. During loading, the goods are placed on the top surface of the bracket 22 and placed on the picking base 34 along with the bracket 22. Through the engagement of the limiting groove 215, the picking positioning groove 216, and the limiting block 311 and positioning block 312, the bracket 22 achieves an accurate and stable loading state on the picking base 34.

[0042] Under the meshing action of the drive gear 314 and the rack 28, the picking base 34 climbs along the inclined track of the picking track 24. When it reaches the target layer height, the drive structure controls the adjustment baffle 29 to switch the movement path from the inclined track to the corresponding horizontal track entrance, so that the displacement carriage 37 is guided into the horizontal track of that layer. Then, the picking base 34 uses the internal drive mechanism of the picking unit 3 to move laterally along the horizontal track to the designated storage column, and then sends the loaded goods tray 22 into the shelf support 21. Through the engagement of the locking rod 214 and the locking slot 212, the tray 22 is stably locked in the storage position, completing one warehousing operation.

[0043] Example 2: As Figure 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the picking unit 3 includes a side support plate 31 disposed on the side of the picking track 24, a picking pallet 32 ​​fixedly installed on the side of the side support plate 31, an inclined bracket 33 disposed on the top surface of the picking pallet 32, and a picking base 34 slidably connected to the surface of the picking pallet 32 ​​and movable to a designated position for picking up goods. The side of the picking pallet 32 ​​is provided with a sliding groove, and a steering plate 36 is slidably connected inside the sliding groove. The bottom surface of the picking pallet 32 ​​is fixedly connected with a hydraulic telescopic rod 35, and the steering plate 36 is fixedly connected to the output end of the hydraulic telescopic rod 35.

[0044] The material-receiving tray 32 and the inclined bracket 33, which are fixedly connected inside the side support plate 31, form a receiving track that matches the material-receiving track 24, used to connect the movement of the material-receiving base 34. A directional plate 36 is provided inside the material-receiving tray 32. This plate can linearly extend and retract under the drive of the hydraulic telescopic rod 35. Its extended or retracted state changes the contact and guiding conditions of the bottom surface of the material-receiving base 34, thereby cooperating with the internal components of the base to switch the direction of movement. The cross-sectional dimensions of the displacement slide 37 are adapted to the gap between the material-receiving track 24 and the guide bracket 26, and its side is machined with a groove that cooperates with the directional baffle 29.

[0045] When the adjusting baffle 29 is driven to change position, the engagement relationship between the slide and the baffle changes, forcing the displacement slide 37 to move along a preset inclined or horizontal path, thus achieving direction switching. An adjusting rod 38 is fixed inside the displacement slide 37. This rod is driven by a built-in motor and can move the positioning slider 313, thereby slightly adjusting the position of the drive gear 314 relative to the rack 28. This compensates for manufacturing gaps, wear, and other errors, ensuring that the drive gear 314 and the rack 28 are always in an accurate and tight meshing state, guaranteeing transmission rigidity.

[0046] A displacement slide 37 is fixedly connected to the side of the material picking base 34. The displacement slide 37 is slidably connected between the material picking track 24 and the guide bracket 26. An adjustment rod 38 is rotatably connected inside the displacement slide 37. A positioning slider 313 is slidably connected inside the displacement slide 37. The positioning slider 313 is threadedly connected to the surface of the adjustment rod 38. A drive gear 314 is rotatably connected inside the positioning slider 313. The drive gear 314 meshes with the rack 28.

[0047] The material picking base 34 is rotatably connected to a lead screw 318. The side of the material picking base 34 is movably connected to a movable plate 315. The movable plate 315 is equipped with a drive wheel 317. The drive wheel 317 is movably connected to the top surface of the material picking tray 32. The top surface of the movable plate 315 is movably connected to a telescopic rod 316. The telescopic rod 316 is movably connected to the inside of the material picking base 34. The outer surface of the lead screw 318 is threadedly connected to a threaded sleeve 321. The outer surface of the threaded sleeve 321 is fixedly connected to a movable material picking seat 39. The movable material picking seat 39 is equipped with a traveling wheel 319. The traveling wheel 319 is movably connected to the top surface of the movable pad 25.

[0048] The material-retrieving base 34 houses a motor that drives the lead screw 318 to rotate, and a movable plate 315 is located at its opposite end. The movable plate 315 is hinged to the material-retrieving base 34, and its unfolding angle is controlled by a telescopic rod 316. A drive wheel 317 is installed inside the movable plate 315, which can roll on the surface of the adjusting plate 36. The movable material-retrieving seat 39 has a threaded sleeve 321, which forms a helical pair connection with the lead screw 318, converting the rotational motion of the lead screw into precise linear motion of the movable material-retrieving seat 39 along the transverse direction of the base. In addition, the movable material-retrieving seat 39 also has a hydraulic rod 320 installed inside, used to drive the top plate 310 for lifting operations.

[0049] The movable material handling seat 39 is internally fixedly connected to a hydraulic rod 320. The output end of the hydraulic rod 320 is fixedly connected to a top plate 310. One end of the top surface of the top plate 310 is fixedly connected to a positioning block 312. The middle of the top surface of the top plate 310 is fixedly connected to a limiting block 311. The positioning block 312 is engaged inside the material handling positioning groove 216, and the limiting block 311 is engaged inside the limiting groove 215.

[0050] In this embodiment, during material handling, the adjusting rod 38 first drives the positioning slider 313 to displace, causing the drive gear 314 to mesh tightly with the rack 28, thereby establishing a reliable lifting driving force. Simultaneously, the motor-driven adjusting baffle 29 within the guide bracket 26 actuates, opening the transverse track entrance corresponding to the target layer, while blocking the inclined track from other layer tracks. The displacement carriage 37 then climbs along the inclined track under the gear and rack engagement, accurately stopping at the entrance end of the transverse track under the limiting effect of the adjusting baffle 29 upon reaching the target layer. During the climbing phase, the telescopic rod 316 pushes the movable plate 315 to unfold 45°, keeping it parallel to the lateral working surface of the adjusting plate 36. The drive wheel 317 on the movable plate 315 rolls on the surface of the adjusting plate 36, forming an auxiliary support torque to counteract the overturning tendency generated during inclined lifting, ensuring the stability of the material handling base 34 throughout the entire process.

[0051] When the material-retrieving base 34 stops at the transverse track inlet, the telescopic rod 316 drives the movable plate 315 to reset, and at the same time, the hydraulic telescopic rod 35 extends the adjusting plate 36, so that the drive wheel 317 on the bottom surface of the movable plate 315 lands on the adjusting plate 36. At this time, the drive wheel 317 rolls along the adjusting plate 36, driving the entire material-retrieving base 34 to move along the transverse track to the designated position. After it reaches the position, the rotating lead screw 318 drives the movable material-retrieving seat 39 to move laterally through the threaded sleeve 321, accurately reaching below the bottom surface of the target bracket 22;

[0052] Next, the hydraulic rod 320 lifts the top plate 310, and the positioning block 312 and the limiting block 311 on the top surface of the top plate 310 respectively engage in the material picking positioning groove 216 and the limiting groove 215, achieving accurate picking of the bracket 22. The hydraulic rod 320 continues to rise until the locking rod 214 completely disengages from the locking groove 212, releasing the bracket 22 from the shelf. Subsequently, the lead screw 318 drives the movable picking seat 39 to carry the bracket 22 back into the picking base 34. The displacement slide 37 and the related mechanisms of the movable plate 315 then work together to return the picking base 34 along the original path to the bottom entrance, allowing the goods stored in the bracket 22 to be quickly retrieved.

[0053] The working principle of this shuttle-type multi-functional intelligent warehouse racking will be explained in detail below.

[0054] like Figure 1-10 As shown, by combining multiple modular rack supports 21, the overall warehouse rack has a right-angled trapezoidal outline, with storage space decreasing layer by layer from bottom to top. The arrangement of goods strictly follows the principle of bottom-heavy and top-light to optimize structural stress and reduce the risk of tipping over. The side of the rack is fixedly connected to the picking rail 24 and the guide bracket 26, which together form a motion auxiliary frame that integrates lifting and lateral movement, so that one picking base 34 can cover multiple layers and multiple rows of storage positions.

[0055] Upon receiving the goods, the goods are first placed on the top surface of the tray 22, and then the tray 22 is placed on the picking base 34. Accurate loading of the tray 22 is achieved through the engagement of the limiting groove 215, the picking positioning groove 216, the limiting block 311, and the positioning block 312. The picking base 34, driven by the meshing of the drive gear 314 and the rack 28, ascends along the inclined track of the picking track 24. Upon reaching the target layer height, the drive structure controls the adjustment baffle 29 to switch the path from the inclined track to the corresponding horizontal track entrance, allowing the displacement slide 37 to be guided into the horizontal track of that layer. Subsequently, driven by the inside of the picking unit 3, the picking base 34 moves laterally along the horizontal track to the designated column, sending the loading tray 22 into the shelf support 21. The storage position is locked by the engagement of the locking rod 214 and the locking slot 212, completing the receiving process.

[0056] During material handling, the adjusting rod 38 first drives the positioning slider 313 to move, causing the drive gear 314 to mesh tightly with the rack 28, establishing a reliable lifting driving force. The motor inside the guide bracket 26 drives the adjusting baffle 29 to open the transverse track entrance of the target layer, while simultaneously blocking the inclined track from other layers. As the displacement carriage 37 climbs along the inclined track, the telescopic rod 316 pushes the movable plate 315 to unfold 45°, keeping it parallel to the working surface of the adjusting plate 36. The drive wheel 317 on the movable plate 315 rolls on the surface of the adjusting plate 36, forming an auxiliary support torque to counteract the overturning tendency during inclined lifting, ensuring the stability of the material handling base 34. Upon reaching the target layer, the displacement carriage 37 accurately stops at the transverse track entrance end under the limitation of the adjusting baffle 29. The telescopic rod 316 then drives the movable plate 315 to reset, and the hydraulic telescopic rod 35 extends the adjusting plate 36, so that the drive wheel 317 falls onto the adjusting plate 36 and rolls along it, driving the material picking base 34 to move along the transverse track to the designated position.

[0057] Once in position, the lead screw 318 rotates, driving the movable material-picking seat 39 laterally to below the bottom surface of the target bracket 22 via the threaded sleeve 321. The hydraulic rod 320 lifts the top plate 310, causing the positioning block 312 and the limiting block 311 to engage with the picking positioning groove 216 and the limiting groove 215 respectively, completing the pickup. The hydraulic rod 320 continues to rise until the locking rod 214 completely disengages from the groove 212, releasing the bracket 22 from the shelf. Subsequently, the lead screw 318 drives the movable material-picking seat 39 to carry the bracket 22 back into the picking base 34. The displacement slide 37 and the movable plate 315 work together to return the picking base 34 along the original path to the bottom entrance, allowing for quick retrieval of the goods inside the bracket 22.

[0058] In summary, this paper mainly optimizes the structural stress by using right-angled trapezoidal racks and a bottom-heavy, top-light cargo distribution to reduce the risk of tipping over. It also utilizes integrated lifting and lateral movement tracks to enable a single unit to cover all storage locations. The picking base is positioned through multiple interlocking mechanisms to ensure stable tray transfer. The directional baffle and auxiliary support effectively ensure smooth climbing and reversing postures. Combined with hydraulic jacking and unlocking and screw lateral movement, automated storage and retrieval are achieved, thereby significantly improving warehouse space utilization, operational efficiency, and operational reliability.

[0059] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
