Description
Technical Field
[0001] This invention relates to an automated outbound storage unit and a three-dimensional storage warehouse, belonging to the field of storage equipment technology. Background Technology
[0002] In existing production workshops, various materials and tools, such as angle irons and trolleys, are often numerous and of varying specifications, resulting in scattered storage that is difficult to organize and manage systematically. Currently, the most common warehousing method is simple shelving storage, where materials are directly stacked on the various layers of fixed shelves.
[0003] While this method is simple in structure and low in cost, it also has several problems: First, for large, heavy items, such as pallet trolleys, forklifts are often required. However, due to the fixed structure of the shelving and limited operating space, forklifts can only access the shelving from the front, making operations difficult. Furthermore, retrieving items further inside often requires moving items on the outside, which is both time-consuming and labor-intensive. Second, mixing materials of different sizes can easily lead to disarray, making inventory and classification difficult and potentially causing inaccurate inventory information. In addition, exposed materials and tools are susceptible to contamination from workshop dust and oil, and prolonged storage can lead to rust and damage, affecting their lifespan. Summary of the Invention The purpose of this invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.
[0004] The technical solution provided by this invention is as follows: An automated outbound storage unit includes a column, supporting rails, and a mobile storage system. Two supporting rails are arranged parallel to each other on the left and right sides of the column, and the cross-section of the supporting rails is frame-shaped. The mobile storage system includes a drawer box, a moving beam, and a pull-out drive assembly. The moving beam is located below the drawer box and inserted into the supporting rails, and the moving beam is connected to the drawer box. The drawer box spans above the two supporting rails. The pull-out drive assembly includes a drive mechanism, a rack, and a fixed gear. The rack is fixed to the bottom of the moving beam, and the fixed gear is rotatably mounted on the supporting rails. The rack meshes with the fixed gear, and the drive mechanism is connected to the fixed gear in a transmission manner.
[0005] Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention, through the combined design of columns, supporting rails and a mobile warehouse system, utilizes a drive mechanism to drive the fixed gear and the rack at the bottom of the moving beam to achieve automatic pull-out of the drawer box; compared with traditional fixed shelves, there is no need for manual searching or limited front operation, and materials (especially large items such as carts) can be directly moved out of the shelf body, facilitating docking with forklifts and other equipment, and greatly improving the efficiency of picking and placing; at the same time, the drawer box is straddling two supporting rails, and the combination of the moving beam and the frame-type supporting rails makes the structure stable and the load-bearing capacity strong.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Furthermore, the length of the rack is less than or equal to half the length of the moving beam.
[0008] The beneficial effect of adopting the above-mentioned further solution is that it ensures that when the drawer box is fully extended, at least half of the length of the moving beam is still retained inside the support rail beam. This part of the moving beam that remains inside plays a supporting role and can effectively prevent the front end of the drawer box from sinking or tipping over when it is suspended in the air or carrying heavy objects, thereby ensuring the stability and safety of the entire pull-out process and the fully extended state.
[0009] Furthermore, the drawer box includes a base plate, a front stop, a rear stop, and multiple sliding rollers. The front stop and the rear stop are respectively disposed at the front and rear ends of the base plate. The sliding rollers are rotatably disposed below the base plate and can roll along the upper surface of the support rail beam. The movable beam is located below the base plate and one end of it is fixedly connected to the front stop.
[0010] The beneficial effects of adopting the above-mentioned further solution are that the front and rear stops form a reliable enclosure for the materials, preventing them from slipping during the pulling process; multiple sliding rollers transform the sliding friction between the drawer box and the support rail beam into rolling friction, making the pulling action effortless and smooth; the moving beam is fixedly connected to the front stop, ensuring that the drawer box and the moving beam move synchronously.
[0011] Furthermore, it also includes at least one guide roller, which is mounted on the end of the moving beam away from the front stop.
[0012] The beneficial effect of adopting the above-mentioned further solution is that when the moving beam extends from the support rail beam, the guide roller installed at the end of the moving beam can contact the inner wall of the support rail beam, providing additional rolling support and guidance during the pulling process. This prevents the far end of the moving beam from drooping or swinging due to suspension or force, reducing the frictional resistance between the moving beam and the support rail beam, and ensuring that the entire pulling process is more stable and straight, thus playing a role in balance and stability.
[0013] Furthermore, the support rail beam is made of hollow square tube, and the moving beam is inserted inside the hollow square tube. The cross-sectional shape of the moving beam is adapted to the inner cavity shape of the hollow square tube, and an insertion gap is left between the moving beam and the base plate.
[0014] The advantages of adopting the above-mentioned further solution are that the hollow square tube provides a full-length support and guide channel for the moving beam, ensuring the straightness and stability of the moving beam's telescopic movement, and effectively preventing dust and debris from falling in and affecting the moving parts; the shape of the moving beam is adapted to the inner cavity of the square tube, enhancing its torsional resistance. The insertion gap between the moving beam and the base plate avoids interference between the moving beam inserted into the hollow square tube and the base plate.
[0015] Furthermore, the storage unit includes two mobile warehouse systems, which are located on the front and rear sides of the column, respectively, and the moving beams of the two mobile warehouse systems are respectively inserted into the two support rail beams on both sides of the column.
[0016] The beneficial effects of adopting the above-mentioned further scheme are that a single column and a pair of supporting rails can simultaneously support two independent mobile warehouse systems, which greatly increases the storage density, doubles the space utilization rate, and allows the two mobile warehouse systems to operate independently, storing and retrieving different materials, thus greatly optimizing the warehouse layout and storage capacity.
[0017] Furthermore, the column is located in the middle of the two supporting rail beams.
[0018] The beneficial effect of adopting the above-mentioned further solutions is that it improves the load-bearing capacity and long-term reliability of the storage unit.
[0019] Furthermore, at least one reinforcing rib connects the two supporting rail beams.
[0020] The beneficial effect of adopting the above-mentioned further solution is that the reinforcing rib connects the left and right support rail beams into an integral frame, which significantly enhances the lateral rigidity and stability of the support rail beam assembly when bearing the load of the drawer box, and prevents the rail beam from undergoing outward deformation or relative displacement due to stress.
[0021] Furthermore, multiple layers of support rails are provided along the height direction of the column, and each layer of support rails is equipped with a mobile cargo storage system.
[0022] The beneficial effect of adopting the above-mentioned further solution is that it expands in multiple layers in the vertical direction, making full use of the height space of the factory. Users can set different floor heights as needed to classify and store various materials, thereby increasing storage capacity.
[0023] The present invention also provides a three-dimensional storage warehouse, including the aforementioned automatic dispensing storage unit, wherein multiple automatic dispensing storage units are arranged in an array.
[0024] Compared with existing technologies, the technical solution provided by this invention has the following advantages: The three-dimensional storage warehouse constructed by this invention, through the matrix arrangement of multiple automated storage units, can be built into a large-scale, high-density intelligent storage system. Each unit can independently and automatically perform outbound and return operations, with a compact layout that effectively improves space utilization and the level of warehouse automation.

Furthermore, the concepts of "connection" and "linkage" mentioned in this application, unless otherwise specified, are considered to include both direct connection (linkage) and indirect connection (linkage).

They are intended to facilitate explanation and simplify the description process, and are not absolute limitations on the actual location, construction method, or operating mode of the described device or element. Therefore, these terms should not be construed as restrictive interpretations of the content of this application.
[0030] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.
[0031] Example 1: like Figure 1 and Figure 2 As shown, an automated outbound storage unit includes a column 100, support rails 200, and a mobile storage system 300. Two support rails 200 are arranged parallel to each other on the left and right sides of the column 100, and the cross-section of each support rail 200 is frame-shaped. The mobile storage system 300 includes a drawer box 310, a moving beam 321, and a pull-out drive assembly 320. The moving beam 321 is located below the drawer box 310 and inserted into the support rails 200. The moving beam 321 and the drawer box 310 are connected to the support rails 200. The drawer box 310 is connected; the drawer box 310 spans above the two support rail beams 200; the pull-out drive assembly 320 includes a drive mechanism, a rack 322 and a fixed gear 323; the rack 322 is fixed to the bottom of the moving beam 321, the fixed gear 323 is rotatably mounted on the support rail beam 200, the rack 322 meshes with the fixed gear 323, the fixed gear 323 is mounted on the gear shaft 324 by a key, and the drive mechanism is connected to the gear shaft 324.
[0032] This invention utilizes a combined design of columns 100, support rails 200, and a mobile warehouse system 300. A drive mechanism engages a fixed gear 323 with a rack 322 at the bottom of the moving beam 321, enabling automatic pull-out of the drawer box 310. Compared to traditional fixed shelves, this eliminates the need for manual searching or front-facing operation, allowing materials (especially large items 500 such as trolleys) to be directly removed from the shelf body, facilitating connection with forklifts and other equipment. Furthermore, the drawer box 310 straddles two support rails 200, and the insertion of the moving beam 321 with the frame-type support rails 200 results in a stable structure with strong load-bearing capacity.
[0033] More specifically, the length of the rack 322 is less than or equal to half the length of the moving beam 321. When the drawer box 310 is fully extended, at least half of the length of the moving beam 321 remains inside the support rail beam 200. This portion of the moving beam 321 remaining inside provides support, effectively preventing the front end of the drawer box 310 from sinking or tipping over when suspended or carrying heavy objects, thus ensuring the stability and safety of the entire pull-out process and the fully extended state. Alternatively, a counterweight can be placed at one end of the moving beam 321 from the drawer box 310. The weight of the counterweight balances the weight of the material at the front end of the drawer box 310, further enhancing the stability of the drawer box 310 in the extended state and preventing the risk of tipping over due to a shift in the center of gravity. This is particularly suitable for storing heavier materials or when the drawer box 310 has a large extended length.
[0034] The drawer box 310 includes a base plate 311, a front stop 312, a rear stop 313, and multiple sliding rollers 314. The front stop 312 and the rear stop 313 are respectively disposed at the front and rear ends of the base plate 311. The sliding rollers 314 are rotatably disposed below the base plate 311 and can roll along the upper surface of the support rail beam 200. The movable beam 321 is located below the base plate 311, and one end of it is fixedly connected to the front stop 312. The front and rear stops 313 form a reliable enclosure for materials, preventing them from slipping during the drawer's operation. The multiple sliding rollers 314 convert the sliding friction between the drawer box 310 and the support rail beam 200 into rolling friction, making the drawer operation effortless and smooth. The movable beam 321 is fixedly connected to the front stop 312, ensuring that the drawer box 310 and the movable beam 321 move synchronously.
[0035] The storage unit also includes at least one guide roller 325, which is installed at the end of the moving beam 321 away from the front stop 312. When the moving beam 321 extends from the support rail beam 200, the guide roller 325 installed at the end of the moving beam 321 can contact the inner wall of the support rail beam 200, providing additional rolling support and guidance during the pulling process. This prevents the distal end of the moving beam 321 from drooping or swinging due to suspension or force, reducing the frictional resistance between the moving beam 321 and the support rail beam 200, and ensuring a smoother and straighter pulling process, thus playing a balancing and stabilizing role.
[0036] In this embodiment, the support rail beam 200 is a hollow square tube, and the moving beam 321 is inserted inside the hollow square tube. The cross-sectional shape of the moving beam 321 is adapted to the inner cavity shape of the hollow square tube, and an insertion gap is left between the moving beam 321 and the base plate 311. The hollow square tube provides a full-length support and guide channel for the moving beam 321, ensuring the straightness and stability of the moving beam 321's telescopic movement, and effectively preventing dust and debris from falling in and affecting the moving parts. The adaptation of the moving beam 321 to the inner cavity shape of the square tube enhances its torsional resistance. The insertion gap between the moving beam 321 and the base plate 311 avoids interference between the moving beam 321 inserted into the hollow square tube and the base plate 311.
[0037] The working principle of the automated outbound storage unit of the present invention is as follows: When materials need to be stored or retrieved, the control system activates the drive mechanism (such as a motor), which drives the fixed gear 323 to rotate. Since the fixed gear 323 meshes with the rack 322 fixed at the bottom of the moving beam 321, the rotational motion of the gear is converted into the linear motion of the rack 322, thereby driving the moving beam 321 to extend outward or retract inward along the support rail beam 200.
[0038] One end of the moving beam 321 is fixedly connected to the front stop 312 of the drawer box 310, so the linear movement of the moving beam 321 directly drives the synchronous movement of the entire drawer box 310. During the pulling process, the sliding roller 314 at the bottom of the drawer box 310 rolls on the upper surface of the support rail beam 200, converting sliding friction into rolling friction, making the pulling action easy and smooth. At the same time, the guide rail roller 325 installed at the other end of the moving beam 321 contacts the inside of the support rail beam 200 when the moving beam 321 extends or retracts, providing additional rolling support and guidance, preventing the far end of the moving beam 321 from sagging, and ensuring a straight movement trajectory.
[0039] When drawer box 310 needs to be fully extended, the front half of moving beam 321 extends out of support rail beam 200 under the action of the drive assembly, driving drawer box 310 out. Since the length of rack 322 is less than or equal to half the length of moving beam 321, when drawer box 310 is fully extended, moving beam 321 still retains at least half its length inside support rail beam 200, ensuring stability and balance in the extended state. After the storage and retrieval operation is completed, the drive mechanism reverses its rotation, smoothly retracting drawer box 310 to its original storage position through the same transmission chain.
[0040] Example 2: Unlike Example 1, such as Figure 3 and Figure 4As shown, in this embodiment, the storage unit includes two mobile storage systems 300, which are located on the front and rear sides of the column 100, respectively. The moving beams 321 of the two mobile storage systems 300 are respectively inserted into two different support rail beams 200. One column 100 and a pair of support rail beams 200 can simultaneously support two independent mobile storage systems 300, which greatly increases storage density and doubles space utilization. The two mobile storage systems 300 can operate independently, storing and retrieving different materials, thus greatly optimizing the storage layout and storage capacity.
[0041] The column 100 is located in the middle of the two supporting rail beams 200, which can improve the load-bearing capacity and long-term reliability of the storage unit. Specifically, when the column 100 is in the middle position, the force is more even, which can better distribute the pressure from the front and rear sides of the mobile warehouse system 300, avoid structural damage or deformation caused by uneven force, and thus improve the load-bearing capacity of the entire storage unit.
[0042] At least one reinforcing rib 400 connects the two support rail beams 200. The reinforcing rib 400 connects the left and right support rail beams 200 into an integral frame, which significantly enhances the lateral rigidity and stability of the support rail beam 200 assembly when bearing the load of the drawer box 310, and prevents the rail beams from undergoing outward deformation or relative displacement due to stress.
[0043] Example 3: Unlike Example 2, such as Figure 5 As shown, in this embodiment, multiple layers of support rails 200 are arranged along the height direction of the column 100, and each layer of support rails 200 is equipped with a mobile warehouse system 300. This multi-layered vertical expansion fully utilizes the height space of the factory building, allowing users to set different floor heights as needed to classify and store various materials, thereby increasing storage capacity.
[0044] Example 4: like Figure 6 As shown, this embodiment provides an automated storage and retrieval system (AS / RS) including the aforementioned automated retrieval units, with multiple automated retrieval units arranged in an array. By combining multiple automated retrieval units in a matrix arrangement, the AS / RS can be constructed into a large-scale, high-density intelligent storage system. Each unit can independently and automatically perform retrieval and return operations, resulting in a compact layout that effectively improves space utilization and the level of storage automation.
[0045] The pull-out storage unit of this invention allows for the direct extraction of drawers 310 carrying large items 500 from the inside, fully exposing the items 500 to the operating area. Forklifts can easily retrieve these items without needing to penetrate deep into the shelving, significantly improving convenience and efficiency. For storage units with multi-layered and / or front and rear dual-sided mobile storage systems 300, each system can be independently controlled, enabling automatic and orderly storage and retrieval of materials in different locations. Multiple such storage units arranged in a matrix can form a high-density, automated, three-dimensional storage facility, achieving centralized management and efficient logistics operations for large quantities of materials.
[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
