[0001] The present invention relates to the technical field of three-dimensional warehouse equipment, and particularly relates to an automated three-dimensional warehouse system for fiberboards. Background Art

[0002] Automated three-dimensional warehouses can greatly improve the utilization efficiency of warehouse space. However, the external shape and structural dimensions of some existing warehouse shelves for placing fiberboards are fixed. Therefore, only fiberboards with relatively fixed dimensions can be placed. When the dimensions of the fiberboards are too long, they cannot be placed into the warehouse shelves, thus reducing the applicability and space utilization rate of the warehouse. Summary of the Invention

[0003] Aiming at the above-mentioned technical deficiencies, the purpose of the present invention is to provide an automated three-dimensional warehouse system for fiberboards, which has the advantages of facilitating the placement of fiberboards of various dimensions and improving the utilization rate of the warehouse.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an automated three-dimensional warehouse system for fiberboards, including: U-shaped outer frames, a plurality of U-shaped outer frames are stacked on top of each other from top to bottom; Placement grooves, two placement grooves are provided, and the two placement grooves are respectively arranged at both ends of the U-shaped opening of the U-shaped outer frame; Adjustable support seats, two adjustable support seats are provided, and each placement groove is movably provided with an adjustable support seat; Object placement plate assemblies, a plurality of object placement plate assemblies are provided, and two object placement plate assemblies are arranged in parallel in each U-shaped outer frame, and the opposite ends of the object placement plate assemblies are respectively movably arranged on the two adjustable support seats; Lift, the lift is arranged outside the U-shaped outer frame; Among them, the adjustable support seat includes a support seat horizontally slidably arranged on the bottom surface of the placement groove, and a support groove is arranged on the top surface of the support seat; The object placement plate assembly includes an intermediate plate, the opposite ends of the intermediate plate are respectively slidably arranged on the two support grooves, and a plurality of extension plates are rotatably connected to the outer peripheral wall of the intermediate plate along the circumferential direction through rotating shafts.

The position of the slot is adapted to that of the bracket. The thickness of the middle plate is the same as that of the extension plate, and the height of the slot is adapted to the thickness of the middle plate. When the storage plate assembly is moved into the U-shaped opening of the U-shaped outer frame, the support rod can rotate with the shaft of the torsion spring as the axis, so as to facilitate the movement of the storage plate assembly into the U-shaped opening of the U-shaped outer frame. At the same time, the first stop block and the second stop block can protect the support rod.

[0006] Preferably, a buffer rubber pad is arranged at one end of the support rod away from the shaft of the torsion spring. The buffer rubber pad abuts against the top surface in the placement groove, so that the support rod can maintain a state perpendicular to the inner bottom surface of the slot under the action of the torsion spring.

[0007] Preferably, two pressing plates are arranged side by side and at intervals on the inner wall of the bracket near the support rod end. Two sliding blocks are arranged on the opposite side walls of the middle plate. The distance between the two sliding blocks on the same side wall of the middle plate is the same as the distance between the two pressing plates, and the thickness of the sliding block is less than the distance from the bottom surface of the pressing plate to the inner bottom surface of the bracket.

[0008] Preferably, both the middle plate and the extension plate are matrix plate structures. The width of the middle plate is twice the width of the extension plate, and the length of the middle plate is more than twice the length of the extension plate. According to different sizes of the fiberboard, by adjusting the position of the extension plate on the middle plate, it is convenient to place fiberboards of different sizes on the limiting plate.

[0009] Preferably, the top surface of the middle plate and the top surface of the extension plate are on the same horizontal plane, and the bottom surface of the extension plate is adapted to the position of the top surface of the bracket, so that after the position of the extension plate is adjusted on the middle plate, it can be supported by the top surface of the bracket.

The support base can be slidably adjusted in the placement groove to facilitate the placement of the fiberboard.

[0011] Preferably, a plurality of limiting rod grooves are arranged at intervals along the length direction on the bottom surface in the bracket. A limiting rod is vertically connected in the limiting rod groove through a return spring, which is convenient for positioning the extension plate and is beneficial to improving the stability after the limiting plate is placed.

[0012] Preferably, a plurality of bolts are used to connect between two adjacent U-shaped outer frames up and down, which is convenient for stacking corresponding numbers of U-shaped outer frames according to the use needs and is also convenient for disassembly.

[0014] The beneficial effects of the present invention are as follows: 1. Through the arranged storage plate assembly, according to fiberboards of different length dimensions, the extension plate can be rotated and adjusted to different positions on the intermediate plate, and at the same time, the extension plate can movably penetrate through the placement groove, so that the outer dimension of the U-shaped outer frame does not limit the size of the placed fiberboard, thus facilitating the placement of fiberboards of various sizes and improving the applicability and space utilization rate of the warehouse.

[0015] 2. Two storage plate assemblies are arranged in parallel in each U-shaped outer frame, and fiberboards of different sizes can be placed on the two storage plate assemblies respectively, improving the applicability. Description of the Drawings

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1 As Figures 1 to 3, Figures 5 to 7 , Figures 9 to 10 As shown in Figures 5 to 7 and Figures 9 to 10 , the present invention provides an automated three-dimensional warehouse system for fiberboards, which includes a U-shaped outer frame 1. There are multiple U-shaped outer frames 1, and the multiple U-shaped outer frames 1 are stacked on top of each other in sequence from top to bottom. There are two placement grooves 2, and the two placement grooves 2 are respectively arranged at both ends of the U-shaped opening of the U-shaped outer frame 1. There are two adjustment brackets 3, and one adjustment bracket 3 is movably arranged in each placement groove 2. There are multiple object placement board assemblies 4, and two object placement board assemblies 4 are arranged in parallel in each U-shaped outer frame 1. The two opposite ends of the object placement board assembly 4 are respectively movably arranged on the two adjustment brackets 3. A lifting machine 5 is arranged outside the U-shaped outer frame 1. The adjustment bracket 3 includes a bracket 31 slidably arranged horizontally on the bottom surface of the placement groove 2, and a support groove 32 is arranged on the top surface of the bracket 31. The object placement board assembly 4 includes an intermediate board 41, and the two opposite ends of the intermediate board 41 are respectively slidably arranged on the two support grooves 32. A plurality of extension boards 42 are rotatably connected to the outer peripheral wall of the intermediate board 41 along the circumferential direction through a rotating shaft 43.

[0031] The U-shaped outer frames 1 can be stacked in sequence from top to bottom according to needs, and the fiberboards are placed on the intermediate board 41 (the position of the extension board 42 can be adjusted by rotating around the rotating shaft 43 on the intermediate board 41 according to the different lengths or widths of the fiberboards to facilitate the placement of the fiberboards). Then, the intermediate board 41 with the fiberboards placed on it is lifted by the lifting machine 5 to the corresponding position of the U-shaped outer frame 1, so that the intermediate board 41 enters the U-shaped opening of the U-shaped outer frame 1. At this time, the two opposite ends of the intermediate board 41 are respectively located on the two support grooves 32. Also, according to the placement needs, the position of the adjustment bracket 3 can be slidably adjusted in the placement groove 2 to facilitate the placement of the fiberboards.

[0032] Since two object placement board assemblies 4 are arranged in parallel in each U-shaped outer frame 1, the two object placement board assemblies 4 can be sequentially placed into the same U-shaped outer frame 1 one by one through the lifting machine 5, so that the two object placement board assemblies 4 are in a horizontal parallel state.

[0033] Embodiment 2 On the basis of Embodiment 1, as Figures 2 to 7 shown, a strut assembly 6 is movably arranged in the placement groove 2. The strut assembly 6 includes a strut 61, and the strut 61 is rotatably connected to the bottom surface inside the opening of the placement groove 2 through a rotating shaft 62 with a torsion spring. A first stop block 63 and a second stop block 64 are respectively arranged on both sides of the strut 61, and the distance from the first stop block 63 to the rotating shaft 62 with the torsion spring is greater than the length of the strut 61. A slot 65 is arranged on the side wall of the strut 61, and the position of the slot 65 is adapted to that of the support groove 32. The thickness of the intermediate board 41 is the same as that of the extension board 42, and the height of the slot 65 is adapted to the thickness of the intermediate board 41. On the inner wall of the bracket 32 near the end of the support rod 61, two pressing plates 311 are arranged in parallel at intervals. On the opposite side walls of the middle plate 41, two sliding blocks 312 are provided on each. The distance between the two sliding blocks 312 on the same side wall of the middle plate 41 is the same as the distance between the two pressing plates 311. The thickness of the sliding block 312 is less than the distance from the bottom surface of the pressing plate 311 to the inner bottom surface of the bracket 32.

[0034] When the size of the fiber board is small, when the side wall in the length direction of the middle plate 41 is in contact with the side wall in the length direction of the extension plate 42, under the action of the lift 5, the middle plate 41 with the fiber board placed thereon can be conveyed into the U-shaped opening of the U-shaped outer frame 1. Since the position of the slot 65 is adapted to that of the bracket 32, the sliding blocks 312 on the opposite side walls of the middle plate 41 can pass through the slots 65 on the side walls of the corresponding support rods 61 to reach inside the bracket 32 respectively. At this time, the two sliding blocks 312 are respectively located below the two pressing plates 311, which is conducive to maintaining the stable position of the middle plate 41.

[0035] When the size of the fiber is large, the extension plate 42 is rotated with the rotation shaft 43 as the axis toward the side wall of the length direction of the middle plate 41 (at this time, the side wall of the width direction of the middle plate 41 is in contact with the side wall of the width direction of the extension plate 42). When the middle plate 41 moves to the U-shaped opening position of the U-shaped outer frame 1 under the action of the lift 5, the side wall of the extension plate 42 can contact the support rod 61. As the middle plate 41 continues to move into the U-shaped opening of the U-shaped outer frame 1, the extension plate 42 can contact the support rod 61, so that the support rod 61 1 The U-shaped outer frame 1 is rotated in the direction of the U-shaped opening with the rotating shaft 62 with the torsion spring as the axial direction (the support rod 61 is rotated 90 degrees from the vertical state to the horizontal state, that is, the support rod 61 can be rotated to fit the bottom surface of the opening of the placement groove 2 (and when the slider 312 moves to a position close to the pressing plate 311, the lifting machine 5 can raise the middle plate 41 by a certain height in the vertical height, and this height is greater than the thickness of the pressing plate 311, so that when the middle plate 41 continues to move horizontally, the extension plate 42 will not interfere with the pressing plate 311; when After the slider 312 moves to a position offset from the pressure plate 311, the lifter 5 lowers the middle plate 41, so that the bottom surface of the extension plate 42 is located on the top surface in the bracket 32); the stopper 1 63 and the stopper 2 64 provided at the same time can protect the support rod 61; when the middle plate 41 moves into the U-shaped opening of the U-shaped outer frame 1, the support rod 61 returns to its original position under the action of the rotating shaft 62 with the torsion spring, and a buffer rubber pad 611 is provided at one end of the support rod 61 away from the rotating shaft 62 with the torsion spring, and the buffer rubber pad 611 The support rod 61 contacts the top surface of the placement groove 2, so that the support rod 61 can remain perpendicular to the bottom surface of the slot 65 after returning to its original position, and can also prevent the opening height of the placement groove 2 at the position of the support rod 61 from being deformed), thereby facilitating the middle plate 41 to move into the U-shaped opening of the U-shaped outer frame 1. At this time, the bottom surface of the extension plate 42 can be located on the top surface of the bracket 32 ​​(because the bottom surface of the extension plate 42 is adapted to the position of the top surface of the bracket 32, that is, the bottom surface of the extension plate 42 is in contact with the top surface of the bracket 31), thereby making the middle plate 41 stably placed.

[0036] The height of block 1 63 and block 2 64 are both smaller than the distance from the bottom surface in the slot 65 to the bottom surface in the placement groove 2, so that the extension plate 42 can conflict with the support rod 61, so that the support rod 61 can rotate in the direction of the U-shaped opening of the U-shaped outer frame 1 with the rotating shaft 62 with the torsion spring as the axial direction, preventing the interference between block 1 63 and block 2 64 and the extension plate 42.

[0037] Embodiment 3 Based on the first embodiment, Figures 5 to 6 , Figures 9 to 11 As shown, the middle plate 41 and the extension plate 42 are both matrix plate structures, the width of the middle plate 41 is equal to twice the width of the extension plate 42 , and the length of the middle plate 41 is greater than twice the length of the extension plate 42 .

[0038] The middle plate 41 is a rectangular plate structure, and there are four rotating shafts 43. The four rotating shafts 43 are respectively arranged at the four corners of the middle plate 41. According to the different sizes of the fiberboard, by adjusting the position of the extension plate 42 on the middle plate 41, it is convenient to place fiberboards of different sizes on the limiting plate. That is, when the length of the fiberboard is longer, the extension plate 42 can be flipped so that the extension plate 42 rotates around the rotating shaft 43 towards the side wall in the width direction of the middle plate 41 (at this time, the side wall in the width direction of the middle plate 41 is in contact with the side wall in the width direction of the extension plate 42), and then a fiberboard with a longer length can be placed; or the extension plate 42 rotates around the rotating shaft 43 towards the side wall in the length direction of the middle plate 41 (at this time, the side wall in the length direction of the middle plate 41 is in contact with the side wall in the length direction of the extension plate 42), and then a fiberboard with a wider width can be placed.

[0039] The top surface of the middle plate 41 and the top surface of the extension plate 42 are on the same horizontal plane, and the bottom surface of the extension plate 42 is adapted to the position of the top surface of the support groove 32. On the one hand, it is convenient for the fiberboard to be stable after being placed on the top surfaces of the middle plate 41 and the extension plate 42; at the same time, it is also convenient to support the extension plate 42 (when the side wall in the width direction of the middle plate 41 is in contact with the side wall in the width direction of the extension plate 42 at this time) through the top surface of the support groove 32.

[0040] Embodiment Four On the basis of Embodiment One, as Figures 2 to 8 shown, the length direction of the placement groove 2 is the same as the length direction of the support groove 32, and the length of the placement groove 2 is greater than the length of the support base 31; a plurality of limiting rod grooves 33 are arranged at intervals along the length direction on the bottom surface in the support groove 32, and a limiting rod 35 is vertically connected in the limiting rod groove 33 through a return spring 34; according to the needs of fiberboard placement, the support base 31 can be slid and adjusted in the placement groove 2 (a fastening bolt can be penetrated through the support base 31, which is convenient for fixing the position of the support base 31 by connecting the support base 31 and the placement groove 2 through the fastening bolt after the position of the support base 31 is adjusted), which is convenient for placing the fiberboard in the U-shaped outer frame 1.

[0041] After the extension plate 42 slides and adjusts its position on the top surface of the support groove 32, the limiting rod 35 can vertically bounce under the action of the return spring 34 (so that the extension plate 42 is located between two adjacent limiting rods 35), which is convenient for stabilizing the position of the extension plate 42 and preventing the extension plate 42 from sliding randomly on the top surface of the support groove 32, thereby improving the stability after the limiting plate is placed.

[0042] Embodiment Five On the basis of Embodiment One, as Figure 1As shown, two adjacent U-shaped outer frames 1 up and down are connected by a plurality of bolts; two adjacent U-shaped outer frames 1 up and down can be connected by bolts, which is beneficial to maintaining the stability after stacking multiple U-shaped outer frames 1 up and down; at the same time, it is also convenient to stack the corresponding number of U-shaped outer frames 1 according to the usage needs, and it is also convenient to disassemble.

[0043] Embodiment Six On the basis of Embodiment One, as Figures 1 to 3 shown, the lift 5 includes a lifting frame 51, and the lifting frame 51 is movably arranged outside the U-shaped outer frame 1; the lifting plate 52 is movably arranged on the lifting frame 51 through a screw-nut assembly, and the position of the lifting plate 52 is adapted to the U-shaped opening position of the U-shaped outer frame 1; the pushing cylinder 53 is horizontally arranged on the lifting plate 52; the clamping jaw 54 is arranged on the piston rod of the pushing cylinder 53; before placing the fiberboard, the storage plate assembly 4 can be placed on the lifting plate 52 first (the fiberboard is placed on the storage plate assembly 4), so that the clamping jaw 54 clamps the middle plate 41 in the storage plate assembly 4, and the screw-nut assembly is started to drive the lifting plate 52 to adjust its position in the vertical height (the screw-nut assembly is a prior art, so it will not be elaborated here), and then the lifting plate 52 can be lifted to the U-shaped opening position of the U-shaped outer frame 1 at different height positions (the U-shaped outer frames 1 can be stacked in different numbers according to needs), and then the pushing cylinder 53 is started to push the middle plate 41 to move into the U-shaped opening of the U-shaped outer frame 1, and the storage of the fiberboard can be completed.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
