Abstract
Description
Technical Field
[0001] This invention relates to the field of automated warehouse technology, specifically to an automated warehouse for storing and retrieving sheet metal. Background Technology
[0002] Automated storage and retrieval systems for wood-based panels are core equipment for the transformation of furniture manufacturing, machinery processing and other industries into smart factories; they achieve automatic storage, retrieval and management of wood-based panels through computer control systems, stacker cranes and conveying systems.
[0003] Chinese patent CN121020074A discloses an automated three-dimensional warehouse for raw materials in furniture production. By setting buffer bladders inside the storage panels, when the boards are placed, their own weight compresses the buffer bladders, causing them to deflate and fall slowly into the storage tank, avoiding hard collisions between the boards and the storage tank. At the same time, the buffer bladders filling the space between the boards and the storage tank can prevent rigid friction between the two, effectively protecting the paint layer on the bottom wall of the boards. In addition, forklifts transfer and pick up boards through the storage panels, and the forklift arms do not directly contact the boards, effectively avoiding frictional damage between the forklift arms and the bottom wall of the boards.
[0004] However, the aforementioned existing technology has the following drawbacks: it requires a forklift to place the storage pallets on different heights in the storage warehouse. When retrieving storage pallets on higher shelves, the forklift needs to use its forklift arm to lift the pallet to a higher position. At this time, the forklift's overall center of gravity shifts upward. The higher the forklift arm rises, the longer the lever arm for the goods to tip forward. Any small forward tilting force (such as braking inertia) will be amplified, which can easily cause the center of gravity to shift forward and trigger a forward tilting accident, thus posing a certain safety hazard. In addition, when it is necessary to transfer the entire set of pallets in the storage warehouse, the forklift needs to remove them one by one for transfer, resulting in low pallet transfer efficiency. Summary of the Invention
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automated three-dimensional warehouse for storing and retrieving sheet metal.
[0006] The technical solution of this invention: An automated three-dimensional warehouse for storing and retrieving sheet metal, comprising: The support mechanism includes a slide rail, a moving part a, a support arm, a connecting plate, and a base; the slide rails are arranged in pairs and multiple sets are provided; the bases are arranged in pairs and multiple sets are provided, and each set of bases is slidably connected to the corresponding slide rail via a slider; multiple sets of moving parts a are provided and connected to the bottom end of the base; the support arms are arranged in pairs and connected to the base; the support arms are provided with guide grooves; the top of the support arm is connected to a top seat; the connecting plate is connected to the top seats on both sides. The shelving mechanism includes a lifting unit, deformable rods, a top support plate, a middle support plate, a bottom support plate, a moving part b, a moving part c, and a connecting block; the lifting unit is connected to a guide groove; the connecting block is detachably connected to the lifting unit; the deformable rods are arranged in pairs, and multiple sets are provided, with one end of the deformable rod rotatably connected to the connecting block and simultaneously rotatably connected to the top support plate; the moving part c is connected to the top support plate; the bottom support plate is rotatably connected to the other ends of the two sets of deformable rods; the moving part b is connected to the bottom end of the bottom support plate; multiple middle support plates are provided and rotatably connected to the two sets of deformable rods.
[0007] Preferably, the lifting part includes a motor a, a screw a, a nut block and a slot plate; the screw a is rotatably disposed inside the guide groove; the motor a is disposed on the top seat and its output end is connected to the screw a; the nut block is slidably connected to the guide groove and threadedly connected to the screw a; the slot plate is connected to the nut block.
[0008] Preferably, the adapter block is inserted into the slot; the adapter block and the slot plate are connected by bolts and nuts.
[0009] Preferably, the moving part a includes a U-shaped plate a, a moving wheel a, and a motor b; the U-shaped plate a is connected to the bottom of the base; the moving wheel a is rotatably located inside the U-shaped plate a; the motor b is located on the U-shaped plate a and its output end is connected to the moving wheel a.

[0012] Preferably, both the middle support plate and the bottom support plate are equipped with gauge lines to facilitate workers in placing the panels within the designated area.
[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: By incorporating a support mechanism and a racking mechanism, and by staggering the top, middle, and bottom support plates of the racking mechanism to form a stepped structure, the height of the equipment can be significantly reduced. This eliminates the need for the forklift arm to lift heavy equipment to a high position, preventing excessive upward shift of the forklift's center of gravity, shortening the lever arm for tilting the equipment forward, ensuring stability during forklift operation, and eliminating safety hazards. For lightweight equipment, workers can choose to manually place the equipment while simultaneously coordinating with the forklift to complete the storage operation, significantly improving equipment placement efficiency and reducing reliance on forklifts for equipment storage and retrieval, thus increasing the flexibility of equipment storage and retrieval.

Then, the shelving mechanism is connected to the lifting part at the storage location, and the shelving mechanism carries the boards back to their original position to realize the overall transfer function of the boards. There is no need to transfer the boards one by one, which significantly improves the transfer efficiency of the boards. Attached Figure Description

[0017] Example 1, as Figures 1-7 As shown, the present invention proposes an automated three-dimensional warehouse for storing and retrieving sheet metal, which includes a support mechanism and a racking mechanism; The support mechanism includes a slide rail 1, a moving part a, a support arm 3, a connecting plate 9, and a base 2. The slide rails 1 are arranged in pairs, with multiple sets. The bases 2 are also arranged in pairs, with multiple sets. Each set of bases 2 is slidably connected to the corresponding slide rail 1 via a slider 18 (when a base 2 disengages from the slide rail 1, the slider 18 on one side of the base 2 does not separate from the slide rail 1, thus guiding the subsequent sliding of the base 2 back to the inside of the slide rail 1). Multiple sets of the moving part a are connected to the bottom of the base 2. The moving part a includes a U-shaped plate a, a moving wheel a4, and a motor b5. The U-shaped plate a is connected to the bottom of the base 2. The moving wheel a4 is rotatably located inside the U-shaped plate a. The motor b5 is located on the U-shaped plate a, and its output end is connected to the moving wheel a4. The support arms 3 are arranged in pairs and connected to the base 2. A guide groove is provided on the support arm 3. A top seat 19 is connected to the top of the support arm 3. The connecting plate 9 is connected to the top seats 19 on both sides. The shelving mechanism includes a lifting unit, deformable rods 6, a top support plate 11, a middle support plate 7, a bottom support plate 8, a moving part b, a moving part c, and a connecting block 20; the lifting unit is connected to the guide groove; the connecting block 20 is detachably connected to the lifting unit; the deformable rods 6 are arranged in pairs, with multiple sets provided, one end of each deformable rod 6 being rotatably connected to the connecting block 20 and simultaneously rotatably connected to the top support plate 11; the moving part c is connected to the top support plate 11; the bottom support plate 8 is rotatably connected to the other ends of the two sets of deformable rods 6; the moving part b is connected to... Attached to the bottom end of the bottom support plate 8, the moving part b includes a U-shaped plate b24, a moving wheel b23, and a motor c21; the U-shaped plate b24 is connected to the bottom support plate 8; the moving wheel b23 is rotatably connected to the inside of the U-shaped plate b24; the motor c21 is mounted on the U-shaped plate b24 and its output end is connected to the moving wheel b23; the middle support plate 7 has multiple sections and is rotatably connected to two sets of deformable rods 6; both the middle support plate 7 and the bottom support plate 8 are provided with gauge lines 22 to facilitate workers placing the sheet material within the designated area (see reference). Figure 1 The area to the right of gauge length line 22 is the designated area, and the area to the left of gauge length line 22 is the reserved area. As the top support plate 11, the middle support plate 7, and the bottom support plate 8 shift synchronously and the spacing gradually changes, the reserved area is to ensure that the plates on them do not touch the upper support plates.
[0018] In this embodiment, both the shelving mechanism and the support mechanism are provided in multiple rows; one side of each row of shelving mechanism needs to be reserved for loading the boards; no operating space needs to be reserved between adjacent shelving mechanisms in the same row. When loading boards, the moving part a at the corresponding shelf mechanism is activated. Motor b5 is then started, driving the moving wheel a4 to rotate, which in turn drives the base 2 to move along the slide rail 1. The base 2 then moves the support arm 3 and the shelf mechanism, causing the shelf mechanism to move laterally and completely separate from the adjacent shelf mechanisms. Before this process, the lifting part moves the shelf mechanism upwards, which in turn moves the moving part b upwards, away from the ground, to prevent the moving wheel b23 from rubbing against the ground during the lateral movement. After the shelf mechanism has completely moved laterally (at this time, the slider 18 on one side of the base 2 is still...), (Sliding connection with slide rail 1), the lifting unit is used again to drive the rack mechanism to move down, so that the moving wheel b23 contacts the ground to share the weight of the rack mechanism; then the motor c21 is turned on, and the motor c21 drives the moving wheel b23 to rotate slowly, so that the moving wheel b23 drives the bottom support plate 8 to move slowly longitudinally (in a direction perpendicular to the lateral movement direction of the rack mechanism), and at the same time, the lifting unit drives the top support plate 11 to move down slowly. At this time, the deformable rods 6 on both sides will rotate relative to the top support plate 11, the middle support plate 7, and the bottom support plate 8 and be in an inclined state. During this process, the top support plate 11, the middle support plate 7, and the bottom support plate 8 are tilted. The support plates 8 will gradually stagger from their vertical arrangement, and the top support plate 11 and the middle support plate 7 will gradually decrease in position and remain horizontal, eventually forming a stepped shape. For heavy sheet metal, a forklift can be used to place the sheet metal on the top support plate 11, the middle support plate 7, or the bottom support plate 8. Because the height of the top support plate 11 and the middle support plate 7 is significantly reduced, the forklift arm does not need to lift the heavy sheet metal to a high position, avoiding excessive upward shift of the forklift's overall center of gravity, shortening the lever arm for the sheet metal to tilt forward, ensuring stability during forklift operation, and eliminating safety hazards. For lightweight sheet metal, workers... The storage operation can be completed manually with the help of a forklift, which can significantly improve the efficiency of the storage and retrieval of the boards. This reduces the reliance on forklifts and increases the flexibility of the storage and retrieval. After the boards are placed, motor C21 is turned on again to reset the bottom support plate 8. At the same time, motor A10 is turned on to move the top support plate 11 upward. At this time, the top support plate 11, the middle support plate 7, and the bottom support plate 8 gradually restore the boards to their vertical alignment. Finally, the moving part A drives the base 2 to move to the inside of the slide rail 1, realizing the function of the rack mechanism resetting the boards.
[0019] It should be noted that the boards used in this embodiment are those required for furniture production, and multiple boards are stacked and bundled before storage (3-4 boards are bundled into a stack).
[0020] It is worth noting that the core design of automated warehouses is to ensure a smooth and safe storage and retrieval process. For stacks of boards that have been stacked and bundled into a stable whole, the main function of the racks is to provide stable support and passive restraint, so there is no need to actively clamp them during static storage. Therefore, no clamping structures are provided on the top support plate 11, the middle support plate 7 and the bottom support plate 8.
[0021] It should be noted that, referring to Figure 1 The bottom support plate 8 can be moved to the right or left to achieve the function of the top support plate 11, the middle support plate 7 and the bottom support plate 8 being staggered to form a stepped shape.
[0022] Example 2, as Figure 3-7 As shown, this invention proposes an automated three-dimensional warehouse for storing and retrieving sheet metal. Compared to Embodiment 1, this embodiment further details the structure of the lifting unit and the moving unit c. The lifting unit includes a motor a10, a screw a12, a nut block, and a slot plate 17. The screw a12 is rotatably disposed inside the guide groove. The motor a10 is disposed on the top seat 19, and its output end is connected to the screw a12. The nut block is slidably connected to the guide groove and threadedly connected to the screw a12. The slot plate 17 is connected to the nut block. The adapter block 20 is inserted into the slot. The adapter block 20 and the slot plate 17 are connected by bolts and nuts. A guide hole is provided on the top support plate 11. The moving unit c includes a caster 13, a screw b14, a plate c15, and a guide rod 16. The screw b14 is rotatably disposed on the top support plate 11. The plate c15 is threadedly connected to the screw b14. The guide rod 16 is slidably connected to the guide hole and connected to the plate c15. The caster 13 is connected to the bottom end of the guide rod 16.
[0023] In this embodiment, the motor a10 drives the screw a12 to rotate clockwise or counterclockwise, which can control the nut block to rise or fall, thereby driving the slot plate 17 to rise or fall. The slot plate 17 drives the adapter block 20 to rise or fall, and the adapter block 20 drives the top support plate 11 to rise or fall.
[0024] When it is necessary to transfer the entire sheet material on the racking mechanism, the top support plate 11, middle support plate 7, and bottom support plate 8 can be staggered, with the top support plate 11 and middle support plate 7 gradually lowering and maintaining a horizontal position, ultimately forming a stepped shape. Then, rotate screw b14 to move plate c15 down, and plate c15 drives caster 13 down through guide rod 16 to contact the ground. Then, remove the bolts and nuts between the adapter block 20 and the slot plate 17, and pull the adapter block 20 out of the slot plate 17. At this point, the racking mechanism is equivalent to a stepped transfer vehicle. The moving part b can drive the shelf mechanism to move, realizing the overall transfer function of the board; at the same time, the shelf mechanism at the storage position is dismantled, and then the shelf mechanism carrying the board to be transferred is connected to the lifting part at the storage position (that is, the connecting block 20 is connected to the slot plate 17), so that the top support plate 11, the middle support plate 7, and the bottom support plate 8 are restored to the vertical arrangement. Finally, the support mechanism carries the shelf mechanism to the slide rail 1, realizing the overall transfer function of the board, without the need to transfer the board one by one, which significantly improves the transfer efficiency of the board.
[0025] It should be noted that in automated warehouses, goods often need to be relocated. For example, best-selling items (frequent inbound and outbound) can be moved to the location closest to the entrance and exit, while slow-moving items (infrequent inbound and outbound) can be moved to the back of the warehouse. This can shorten the average travel distance of the equipment and improve the overall throughput efficiency. The location of goods can also be adjusted according to the season or promotional activities. For example, during the rainy season, goods with high moisture requirements can be moved to a drier specific area, or during promotional periods, popular products can be moved to the most easily accessible area.
[0026] The electronic devices in this patent are all controlled by a controller to operate in an orderly manner.
[0027] In summary, when loading boards, the moving part a at the corresponding shelf mechanism is activated. Motor b5 is then started, driving the moving wheel a4 to rotate, which in turn drives the base 2 to move slowly along the slide rail 1. The base 2 then moves the support arm 3 and the shelf mechanism, causing the shelf mechanism to move laterally and completely separate from the adjacent shelf mechanisms. Before this process, the lifting part moves the shelf mechanism upwards, which in turn moves the moving part b upwards, away from the ground, to prevent the moving wheel b23 from rubbing against the ground during the lateral movement. After the shelf mechanism has completely moved laterally (at this time, the slider 18 on one side of the base 2 is still slidably connected to the slide rail 1), then... The lifting mechanism lowers the shelving unit, causing the moving wheels b23 to contact the ground and share the weight of the shelving. Then, motor c21 is activated, causing the moving wheels b23 to rotate slowly. This causes the bottom support plate 8 to move slowly longitudinally (perpendicular to the lateral movement of the shelving). Simultaneously, motor a10 drives the screw a12 to rotate slowly, controlling the nut block to descend slowly. This, in turn, causes the slot plate 17 to descend, which in turn causes the adapter block 20 to descend slowly. The adapter block 20 then causes the top support plate 11 to descend slowly. At this point, the deformable rods 6 on both sides will move relative to the top support plate 11 and the middle support plate 7. The bottom support plate 8 rotates to a tilted position. During this process, the top support plate 11, middle support plate 7, and bottom support plate 8 gradually shift away from their vertical arrangement, and the top support plate 11 and middle support plate 7 gradually lower and remain horizontal, ultimately forming a stepped shape. For heavy plates, a forklift can be used to place the plates on the top support plate 11, middle support plate 7, or bottom support plate 8. Because the height of the top support plate 11 and middle support plate 7 is significantly reduced, the forklift arm does not need to lift the heavy plates to a high position, avoiding excessive upward shift of the forklift's overall center of gravity, shortening the lever arm for the plates to tilt forward, ensuring stability during forklift operation, and eliminating safety hazards. Potential risks: For lightweight sheet materials, workers can choose to manually place the sheet materials while simultaneously using a forklift to complete the storage operation. This can significantly improve the efficiency of sheet material placement, reducing reliance on forklifts for storage and retrieval, and increasing the flexibility of sheet material storage and retrieval. After the sheet materials are placed, motor C21 is turned on again to reset the bottom support plate 8. At the same time, motor A10 is turned on to move the top support plate 11 upward. At this time, the top support plate 11, the middle support plate 7, and the bottom support plate 8 gradually restore the vertical arrangement of the sheet materials. Finally, the moving part A drives the base 2 to move to the inside of the slide rail 1, realizing the function of the rack mechanism resetting the sheet materials.
[0028] When it is necessary to transfer the entire sheet material on the rack mechanism, the rack can be moved horizontally first, so that the top support plate 11, middle support plate 7, and bottom support plate 8 are staggered. Then, the top support plate 11 and middle support plate 7 are gradually lowered and kept horizontal, eventually forming a stepped shape. Then, the screw b14 is rotated to make plate c15 move down. Plate c15 drives the caster 13 to move down and contact the ground through the guide rod 16. Then, the bolts and nuts between the adapter block 20 and the slot plate 17 are removed, and the adapter block 20 is pulled out from the slot plate 17. At this time, the rack mechanism is separated from the support mechanism. It also acts as a stepped transfer vehicle. The moving part b can drive the shelf mechanism to move slowly, realizing the overall transfer function of the board. At the same time, the shelf mechanism at the storage location is dismantled, and then the shelf mechanism carrying the board to be transferred is connected to the lifting part at the storage location (that is, the connecting block 20 is connected to the slot plate 17). The top support plate 11, the middle support plate 7, and the bottom support plate 8 are restored to their vertical arrangement. Finally, the support mechanism carries the shelf mechanism to the slide rail 1, realizing the overall transfer function of the board. There is no need to transfer the board one by one, which significantly improves the transfer efficiency of the board.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
