Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to an automated sheet metal storage rack. Background Technology

[0002] In the current wave of intelligent manufacturing and Industry 4.0 sweeping the globe, modern manufacturing industries, such as machining, building decoration, and furniture manufacturing, are undergoing profound transformations from traditional production models to intelligent and digital transformation. As core raw materials in these industries, the level of intelligence in the storage management and the efficiency of space utilization of sheet metal components have become key indicators for measuring a company's competitiveness.

[0003] A search revealed Chinese patent publication number CN218618444U, which discloses a sheet material storage rack. The rack includes uprights, support beams, and crossbeams. The uprights are fixedly connected by the support beams, and several crossbeams for placing sheet materials are erected between the support beams. Each crossbeam has several roller assemblies along its length, with the upper surface of the roller assembly higher than the upper surface of the crossbeam. Each roller assembly includes a roller, a rotating bolt, and a limiting nut. The roller is rotatably connected to the crossbeam via the rotating bolt, and the roller is fixed to the rotating bolt by the limiting nut. Adjustment seats are provided at both ends of the support beams, and these seats are movably connected to the uprights via a plug-in connection. Mounting seats are provided at both ends of the crossbeams, and locking bolts are installed on the mounting seats. This sheet material storage rack, by adding roller assemblies to the traditional support beams, not only facilitates material loading (simply push the sheet material), but also reduces friction between the sheet material and the support frame, preventing damage to the sheet material surface and effectively improving loading efficiency.

[0004] The above-mentioned methods can reduce friction between the boards and the supports, but manual handling is labor-intensive. Although the improved storage device reduces friction between the boards and the supports by setting rollers, which improves the board storage and retrieval experience to some extent, the overall weight of the boards is large. The storage and retrieval of multi-layer shelves still relies on manual handling, which has the disadvantages of low efficiency and high labor costs. Moreover, when it is necessary to store and retrieve boards at high levels, it is necessary to use auxiliary tools such as forklifts and climbing equipment, which makes the operation cumbersome and poses safety hazards. Therefore, an automated board storage rack is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automated sheet material storage rack, which aims to improve the problems of low efficiency of manual handling and inconvenience of multi-layer storage and retrieval of sheet materials in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated sheet material storage rack includes a column and a picking frame. The column is connected to the picking frame via a lifting mechanism. The column has an internal shelf mechanism, and the picking frame has an internal conveying mechanism. The lifting mechanism includes a top frame, which is fixedly connected to the top inner side of the column. A rotating motor is fixedly connected to the top of the top frame, and a drive rod is fixedly connected to the output end of the rotating motor. Double-layer sprockets are fixedly connected to both ends of the drive rod. A lifting chain is sleeved on the outside of the double-layer sprockets, and connecting components are fixedly connected to both ends of the lifting chain. A support frame is fixedly connected to the bottom of the connecting components, and a stop frame is fixedly connected to the outside of the support frame via a connecting plate. An angle sprocket is rotatably connected to the bottom of the column, and a moving component is rotatably connected inside the support frame. Protective components are fixedly connected to both ends of the top of the top frame.

[0008] The above technical solution involves the following: after the rotating motor starts, it drives the drive rod to rotate, which in turn drives the double-layer sprockets at both ends to rotate. The double-layer sprockets drive the lifting chain to move, and the lifting chain drives the support frame to move up and down along the column through the connecting assembly. The support frame drives the abutment frame to move synchronously through the connecting plate. The abutment frame can push the frame retrieval to achieve lifting and lowering, so that the frame retrieval can cooperate with the conveying mechanism and the shelf mechanism for storing and retrieving the boards. The protective assembly protects the top of the column, the corner sprocket assists the lifting chain in turning, and the moving assembly makes the lifting and lowering process of the support frame more stable and smooth.

[0009] As a further description of the above technical solution:

[0010] The conveying mechanism includes a support frame, with both ends of the support frame fixedly connected to the inner side of the outer side of the picking frame. A positioning motor is fixedly connected to the top of the support frame, and a transmission rod is fixedly connected to the output end of the positioning motor. Control sprockets are fixedly connected to both ends of the transmission rod. A traction chain is sleeved on the outside of the control sprockets. A movable seat is fixedly connected to the outside of the traction chain, and a pull rod is rotatably connected to the inner side of the movable seat.

[0011] Through the above technical solution: after the positioning motor starts, it drives the transmission rod to rotate, the transmission rod drives the control sprockets at both ends to rotate, the control sprockets drive the traction chain to move, the traction chain drives the external movable seat to move along the support frame, and the movable seat can push and pull the board through the pull rod to realize the conveying of the board between the shelf mechanism and the frame picking.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the frame near the column is rotatably connected to receiving pulleys, the inner wall of the frame away from the column is rotatably connected to taking pulleys, and the inner wall of the frame near the support frame is rotatably connected to tightening pulleys. The outer part of the traction chain is sleeved on the outside of the tightening pulley, the inner part of the traction chain is sleeved on the outside of the receiving pulley, and the inner part of the traction chain is sleeved on the outside of the taking pulley.

[0014] Through the above technical solution: the receiving pulley, the taking-off pulley, and the tightening pulley work together to support and guide the traction chain. The tightening pulley is located near the support frame and can apply appropriate tension to the traction chain to ensure that it remains taut during transmission, avoids slippage, and improves transmission efficiency. The receiving pulley and the taking-off pulley are located on the inner wall of the frame near and far from the column, respectively, so that the traction chain forms a reasonable transmission path, ensuring that the movable seat can move smoothly along the predetermined trajectory and realize the accurate conveying of the sheet metal.

[0015] As a further description of the above technical solution:

[0016] The shelf mechanism includes multiple guide rails, the exterior of which are fixedly connected to the inner side walls of the column. Each guide rail, i.e., the side away from the retrieval frame, is threadedly connected to a stop plate. The top of each of the two parallel guide rails is slidably connected to a small roller. A plate frame is rotatably connected to the adjacent side of the small roller. Multiple support rods are fixedly connected to the inner wall of the plate frame. Positioning sensors are fixedly connected to both sides of the plate frame, i.e., the end near the retrieval frame. Pull buckles are fixedly connected to the bottom of the plate frame, i.e., the end near the positioning sensors. The pull buckles are internally engaged with the outside of the pull rods.

[0017] Through the above technical solution: the guide rail provides guidance for the sliding of the plate frame, the abutment plate can limit the sliding range of the plate frame, when the pull rod of the conveying mechanism is engaged in the pull buckle and moves, it can drive the plate frame to slide along the guide rail through the small rollers, thereby realizing the adjustment of the plate storage position, the positioning sensor can detect the position of the plate frame to ensure its accurate docking and frame retrieval, and the support rod is used to support the plate and improve the storage stability.

[0018] As a further description of the above technical solution:

[0019] The connecting assembly includes a main connecting buckle and a secondary connecting buckle. The top of the main connecting buckle is fixedly connected to one end of the lifting chain, and the bottom of the main connecting buckle is fixedly connected to the top inner side of the support frame. The bottom of the secondary connecting buckle is fixedly connected to the other end of the lifting chain, and the top of the secondary connecting buckle is fixedly connected to the bottom inner side of the abutment frame. The outside of the lifting chain is sleeved on the outside of the corner sprocket, and the outside of the support frame is fixedly connected to the outside of the take-up frame.

[0020] Through the above technical solution: the main connecting buckle and the auxiliary connecting buckle respectively securely connect the two ends of the lifting chain to the support frame and the abutment frame, so that the movement of the lifting chain can be effectively transmitted to the frame retrieval. When the rotating motor drives the double-layer sprocket to drive the lifting chain to move, the chain bypasses the corner sprocket to form a reasonable transmission path, and drives the support frame and the abutment frame to rise and fall synchronously through the connecting components, thereby driving the frame retrieval to move smoothly.

[0021] As a further description of the above technical solution:

[0022] The movable component includes a bottom roller and an upper roller. The bottom roller is rotatably connected to the top inner side of the support frame and slidably connected to the outside of the column. The upper roller is rotatably connected to the bottom inner side of the support frame and slidably connected to the outside of the column.

[0023] Through the above technical solution: the bottom roller and the top roller slide up and down on the outside of the column respectively, providing rolling support for the lifting of the support frame and the bottom frame. When the lifting chain drives the support frame and the bottom frame to move, the bottom roller and the top roller roll along the surface of the column, effectively reducing frictional resistance and making the lifting process of the frame removal smoother and more stable.

[0024] As a further description of the above technical solution:

[0025] The protective assembly includes a dustproof shell and a limiting shaft. The bottom of the dustproof shell is fixedly connected to the top of the top frame, and the bottom of the limiting shaft is fixedly connected to the inside of the dustproof shell. The outside of the drive rod is rotatably connected to the inside of the limiting shaft, and the outside of the double-layer sprocket is rotatably connected to the outside of the limiting shaft.

[0026] Through the above technical solution: the dustproof shell encloses the rotating motor, drive rod and other components at the top of the top frame, which can effectively prevent dust and debris from entering and avoid affecting the normal operation of the components, ensuring the cleanliness and operational stability of the equipment. The limiting shaft is fixed inside the dustproof shell, providing rotational support and positioning for the drive rod and double-layer sprocket, so that the drive rod can maintain stable rotation under the drive of the rotating motor, and the double-layer sprocket can also cooperate with the lifting chain for transmission along a predetermined trajectory.

[0027] As a further description of the above technical solution:

[0028] One end of the lifting chain is connected to the main connecting buckle at the top of the support frame, and the other end is connected to the auxiliary connecting buckle at the bottom of the abutment frame via the corner sprocket to change the moving angle. This causes the rotating motor to generate power to drive the drive rod to rotate the double-layer sprocket, slide one end of the lifting chain upward and the other end downward, so that the support frame and the abutment frame slide up and down on the outside of the column by means of the moving component, thereby driving the frame to rise and fall.

[0029] The above technical solution uses a rotating motor as a power source to drive a drive rod that rotates a double-layer sprocket. The lifting chain meshes with the double-layer sprocket, and a corner sprocket changes the chain's movement angle, enabling reverse movement at both ends of the chain. The main and auxiliary connecting buckles securely connect both ends of the chain to the support frame and the abutment frame respectively, ensuring precise transmission of chain movement to the support and abutment frames. The bottom and upper rollers in the moving assembly roll on the outer surface of the column, effectively reducing frictional resistance during lifting and ensuring smooth and precise frame retrieval along the column, thus achieving automated storage and retrieval of panels at different heights.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the automatic drive rod of the rotating motor drives the double-layer sprocket to rotate, thereby causing the lifting chain sleeved on the outside of the double-layer sprocket to pull the overall structure formed by the support frame and the abutment frame through the main connecting buckle and the auxiliary connecting buckle. With the help of the upper roller and the bottom roller, it slides up and down on the outside of the column, thereby realizing the automated vertical lifting and lowering movement of the frame along the column. It can intelligently store and retrieve boards at different height levels, significantly improving the automation and efficiency of board storage and retrieval.

[0032] 2. In this utility model, the positioning motor generates power to control the transmission rod, which drives the control sprocket and the traction chain. The chain is tensioned by the tension pulley, and the connecting pulley and the retracting pulley guide the direction, so that the movable seat drives the pull rod to accurately pull or push the shelf frame of the shelf mechanism to slide along the guide rail. This solves the problems of inconvenient manual handling and low efficiency of inter-layer storage and retrieval when storing boards. It realizes the coordinated operation of the frame retrieval and shelf mechanism, and works with the lifting mechanism to complete the automated storage and retrieval of each layer of boards, achieving the effect of convenient storage and retrieval of each layer of boards.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model provides an automated board storage rack, including a column 1 and a picking frame 2. The column 1 serves as the main support structure of the entire automated board storage rack. The column 1 is connected to the picking frame 2 through a lifting mechanism 4. The picking frame 2 is used to carry and transport boards and is connected to the lifting mechanism 4 to achieve vertical movement. The conveying mechanism 5 on the outer inner side cooperates with the shelf mechanism 3 to realize the storage and retrieval of boards. The shelf mechanism 3 is provided inside the column 1, and the conveying mechanism 5 is provided on the outer inner side of the picking frame 2.

[0044] The lifting mechanism 4 includes a top frame 41, which serves as the top support structure for the lifting mechanism 4 and provides an installation base for the rotary motor 42. The top frame 41 is fixedly connected to the top inner side of the column 1. The rotary motor 42 is fixedly connected to the top of the top frame 41. The rotary motor 42 serves as the power source for the lifting mechanism 4, driving the double-layer sprocket 44 to rotate via the drive rod 43 at its output end, thus providing power for the movement of the lifting chain 45. The output end of the rotary motor 42 is fixedly connected to the drive rod 43, which connects the output end of the rotary motor 42 to the double-layer sprocket 44, transmitting the power of the rotary motor 42. Both ends of the drive rod 43 are fixedly connected to the double-layer sprocket 44, which are sleeved on both ends of the drive rod 43 and cooperate with the lifting chain 45. The rotation of the sprockets drives the lifting chain 45 to move. The double-layer sprocket 44 is sleeved on the outside of the double-layer sprocket 44. 45. The lifting chain 45 transmits the power of the double-layer sprocket 44 through the connecting components 8 at both ends, realizing the up-and-down sliding of the support frame 46 and the abutment frame 48, thereby driving the lifting frame 2 to rise and fall. The two ends of the lifting chain 45 are fixedly connected to the connecting components 8, and the bottom of the connecting components 8 is fixedly connected to the support frame 46. The support frame 46 is used to support the lifting frame 2 and transmit the power of the lifting chain 45. The outside of the support frame 46 is fixedly connected to the abutment frame 48 through the connecting plate 49. The abutment frame 48 and the support frame 46 together support the lifting frame 2 and transmit the power of the lifting chain 45. The bottom of the column 1 is rotatably connected to the corner sprocket 47. The corner sprocket 47 is used to change the moving angle of the lifting chain 45, so that the lifting chain 45 can extend from the top of the column 1 to the bottom and connect to the abutment frame 48. The inside of the support frame 46 is rotatably connected to the moving component 7. The top two ends of the top frame 41 are fixedly connected to the protective component 6.

[0045] Specifically, the automated board storage rack consists of a column 1 and a retrieval frame 2. The column 1 serves as the main support, and the retrieval frame 2 moves up and down via a lifting mechanism 4 to carry and transport boards. The conveying mechanism 5 on its outer inner side works in conjunction with the shelf mechanism 3 inside the column 1 to complete the storage and retrieval of boards. In the lifting mechanism 4, the top frame 41 is fixed to the inner top of the column 1, providing an installation base for the rotating motor 42. The drive rod 43 at the output end of the rotating motor 42 drives the double-layer sprockets 44 at both ends to rotate. The double-layer sprockets 44 cooperate with the sleeved lifting chain 45 to transmit power to the connecting components 8 at both ends. The support frame 46 below the connecting component 8 and the abutment frame 48 connected by the connecting plate 49 jointly support the retrieval frame 2 and move with the lifting chain 45. The corner sprocket 47 at the bottom of the column 1 changes the direction of movement of the lifting chain 45, allowing the chain to extend from the top to the bottom to connect with the abutment frame 48. In addition, the support frame 46 is equipped with a moving component 7, and the protective components 6 at both ends of the top of the top frame 41 provide protection.

[0046] The connecting component 8 includes a main connecting buckle 81 and a secondary connecting buckle 82. The top of the main connecting buckle 81 is fixedly connected to one end of the lifting chain 45, and the bottom of the main connecting buckle 81 is fixedly connected to the inner side of the top of the support frame 46, thereby connecting the lifting chain 45 and the support frame 46 and transmitting the tension of the lifting chain 45. The bottom of the main connecting buckle 81 is fixedly connected to the inner side of the top of the support frame 46. The bottom of the secondary connecting buckle 82 is fixedly connected to the other end of the lifting chain 45, and the top of the secondary connecting buckle 82 is fixedly connected to the inner side of the bottom of the abutment frame 48, thereby connecting the lifting chain 45 and the abutment frame 48 and transmitting the tension and pressure of the lifting chain 45. The top of the secondary connecting buckle 82 is fixedly connected to the inner side of the bottom of the abutment frame 48. The outside of the lifting chain 45 is sleeved on the outside of the corner sprocket 47, and the outside of the support frame 46 is fixedly connected to the outside of the frame 2.

[0047] The movable component 7 includes a bottom roller 71 and an upper roller 72. The bottom roller 71 is rotatably connected to the top inner side of the abutment frame 48 and slidably connected to the outside of the column 1, providing support and guidance for the up and down movement of the abutment frame 48 and reducing the friction between the abutment frame 48 and the column 1. The bottom roller 71 is slidably connected to the outside of the column 1. The upper roller 72 is rotatably connected to the bottom inner side of the support frame 46 and slidably connected to the outside of the column 1, providing support and guidance for the up and down movement of the support frame 46 and reducing the friction between the support frame 46 and the column 1. The upper roller 72 is slidably connected to the outside of the column 1.

[0048] The protective assembly 6 includes a dustproof shell 61 and a limiting shaft 62. The bottom of the dustproof shell 61 is fixedly connected to the top of the top frame 41. The dustproof shell 61 forms a closed protective space to protect the internal transmission components such as the drive rod 43 and the double-layer sprocket 44 from dust and debris. The bottom of the limiting shaft 62 is fixedly connected to the inside of the dustproof shell 61. The limiting shaft 62 limits the rotation position of the drive rod 43 and the double-layer sprocket 44 to ensure their normal rotation. The external rotatable connection of the drive rod 43 is connected to the inside of the limiting shaft 62, and the external rotatable connection of the double-layer sprocket 44 is connected to the outside of the limiting shaft 62.

[0049] One end of the lifting chain 45 is connected to the main connecting buckle 81 at the top of the support frame 46, and the other end is connected to the auxiliary connecting buckle 82 at the bottom of the abutment frame 48 by changing the moving angle through the corner sprocket 47. This causes the rotating motor 42 to generate power to drive the drive rod 43 to rotate the double-layer sprocket 44, which slides one end of the lifting chain 45 upward and the other end downward. This allows the support frame 46 and the abutment frame 48 to slide up and down outside the column 1 via the moving component 7, thereby driving the frame 2 to rise and fall.

[0050] Specifically, in the connecting component 8, the top of the main connecting buckle 81 is fixed to one end of the lifting chain 45, and the bottom end is connected to the inner side of the top of the support frame 46, bearing the transmission of tension. The bottom of the auxiliary connecting buckle 82 is connected to the other end of the lifting chain 45, and the top is fixed to the inner side of the bottom of the abutment frame 48, taking into account both tension and pressure transmission. The lifting chain 45 is wrapped around the corner sprocket 47 to realize the direction change. The bottom roller 71 of the moving component 7 is installed on the inner side of the top of the abutment frame 48 and can roll along the outer wall of the column 1. The upper roller 72 is set on the inner side of the bottom of the support frame 46 and also slides in contact with the outer wall of the column 1. The two together form the support frame. The lifting of the support frame 46 and the abutment frame 48 provides support and guidance, reducing friction. In the protective component 6, the dustproof shell 61 is fixed to the top of the top frame 41, forming a closed space to isolate dust and debris. The internal limiting shaft 62 is fixed inside the dustproof shell 61 and is rotatably connected to the drive rod 43 and the double-layer sprocket 44, constraining its rotation trajectory. During operation, the rotating motor 42 drives the drive rod 43 to drive the double-layer sprocket 44 to rotate, causing one end of the lifting chain 45 to rise and the other end to fall. In conjunction with the moving component 7, the support frame 46 and the abutment frame 48 are lifted and lowered along the column 1, thereby driving the frame 2 to complete the lifting action.

[0051] Reference Figures 1 to 3The conveying mechanism 5 includes a support frame 51, which provides a mounting base for the positioning motor 52 and supports the entire conveying mechanism 5. Both ends of the support frame 51 are fixedly connected to the outer inner side of the frame 2. The positioning motor 52 is fixedly connected to the top of the support frame 51. The positioning motor 52 serves as the power source for the conveying mechanism 5, driving the control sprocket 54 to rotate via the transmission rod 53 at its output end, providing power for the movement of the traction chain 55, and thus driving the movable seat 56 and the pull rod 57. The output end of the positioning motor 52 is fixedly connected to the transmission rod 53, which connects the output end of the positioning motor 52 and the control sprocket 54, transmitting positioning... The power of motor 52 drives the control sprocket 54 to rotate. Both ends of the transmission rod 53 are fixedly connected to the control sprocket 54. The control sprocket 54 cooperates with the traction chain 55. The rotation of the sprocket drives the traction chain 55 to move, thereby moving the movable seat 56. The traction chain 55 is sleeved on the outside of the control sprocket 54. The traction chain 55 is sleeved on the outside of the control sprocket 54, the tension pulley 58, the receiving pulley 59, and the take-off pulley 510, connecting to the movable seat 56 and transmitting the power of the control sprocket 54 to move the movable seat 56. This, in turn, drives the pull rod 57 and the plate frame 33 of the shelf mechanism 3 to move. The traction chain 55 is fixedly connected to the outside of the movable seat 56. The movable seat 56 moves with the traction chain 55, transmitting power from the traction chain 55 to the pull rod 57. The pull rod 57 is rotatably connected to the inner side of the movable seat 56, and its other end engages with the latch 36 of the shelf mechanism 3, transmitting power to the movable seat 56 to pull or push the shelf frame 33. The inner wall of the frame 2, which is close to the column 1, is rotatably connected to pulleys 59. These pulleys 59 change the direction of the traction chain 55, allowing the chain to extend from one side of the support frame 51 to the other side of the column 1, thus pulling the shelf frame 33. Each inner wall of the column 1 is rotatably connected to a pulley 510. The pulley 510 is used to change the direction of the traction chain 55 so that the chain can form a closed loop, realizing the bidirectional movement of the movable seat 56. Each inner wall of the frame 2, which is close to the support frame 51, is rotatably connected to a tension pulley 58. The tension pulley 58 is used to tension the traction chain 55 to ensure that the traction chain 55 maintains appropriate tension during movement and to prevent the chain from slack or slipping. The outer part of the traction chain 55 is sleeved on the outside of the tension pulley 58, the inner part of the traction chain 55 is sleeved on the outside of the receiving pulley 59, and the inner part of the traction chain 55 is sleeved on the outside of the pulley 510.

[0052] Specifically, the conveying mechanism 5 is based on the support frame 51, with both ends fixed to the inner side of the outer side of the frame 2, providing support for the entire mechanism. The positioning motor 52 is installed on the top of the support frame 51 as a power source, driving the control sprockets 54 at both ends to rotate through the transmission rod 53 at the output end. The control sprockets 54 cooperate with the traction chain 55 sleeved on the outside, driving the chain to move. The traction chain 55 surrounds the tension pulley 58, the receiving pulley 59 and the take-off pulley 510, and is fixedly connected to the movable seat 56 on the outside. The movable seat 56 is rotatably connected to the pull rod 57 on the outside. It is engaged with the pull buckle 36 of the shelf mechanism 3 to pull or push the frame 33. The tension pulley 58 is installed on the inner wall of the frame 2 near the support frame 51 to tension the chain. The connecting pulley 59 is located on the inner wall of the frame 2 near the column 1 to change the direction of the chain so that it extends to the side of the column 1. The retracting pulley 510 is set on the inner wall of the frame 2 away from the column 1 to ensure that the chain forms a closed loop and realizes the bidirectional movement of the movable seat 56.

[0053] Reference Figure 3 , Figure 6 and Figure 7 The shelf mechanism 3 includes multiple guide rails 31, which provide guide tracks for the sliding of the shelf frame 33, ensuring stable horizontal movement of the shelf frame 33. The external sides of the multiple guide rails 31 are fixedly connected to the internal side walls of the column 1. Each guide rail 31, i.e., the side away from the frame 2, is threadedly connected to a stop plate 32. The stop plate 32 is used to adjust and limit the sliding range of the shelf frame 33 on the guide rail 31, preventing the shelf frame 33 from sliding off the guide rail 31. Small rollers 35 are slidably connected to the top of each of the two parallel guide rails 31. The small rollers 35 are mounted on the top of the two parallel guide rails 31 and rotatably connected to the shelf frame 33, allowing the shelf frame 33 to slide flexibly on the guide rails 31. A shelf frame 33 is rotatably connected to the adjacent side of the small rollers 35. The shelf frame 33 is used to support the shelf material. The small roller 35 is connected to the guide rail 31 to achieve horizontal sliding, and cooperates with the pull rod 57 of the conveying mechanism 5 to realize the storage and retrieval of the board. Multiple support rods 34 are fixedly connected to the inner wall of the board frame 33. The support rods 34 are used to support and place the board, improving the load-bearing capacity and stability of the board frame 33. Positioning sensors 37 are fixedly connected to both sides of the end of the board frame 33 that is close to the picking frame 2. The positioning sensors 37 are used to detect the position of the board frame 33 to ensure that the board frame 33 can accurately reach the designated position during movement. Pull buckles 36 are fixedly connected to the bottom of the end of the board frame 33 that is close to the positioning sensor 37. The pull buckles 36 are engaged with the pull rod 57 of the conveying mechanism 5 to realize the power transmission between the conveying mechanism 5 and the shelf mechanism 3. The inside of the pull buckle 36 is engaged with the outside of the pull rod 57.

[0054] Specifically, in the shelf mechanism 3, multiple guide rails 31 are fixed to the inner side walls of the column 1 to provide horizontal guidance for the shelf frame 33 and ensure its stable movement. A stop plate 32 is provided on the side of the guide rail 31 away from the frame 2. The sliding range is adjusted and limited by threaded connection to prevent the shelf frame 33 from sliding out. The small rollers 35 at the top of the two parallel guide rails 31 are rotatably connected to the shelf frame 33, allowing the shelf frame 33 to slide flexibly. Multiple support rods 34 inside the shelf frame 33 play the role of supporting the shelf and enhancing the load-bearing stability. Positioning sensors 37 on both sides of the shelf frame 33 near the frame 2 monitor the position of the shelf frame 33 in real time to ensure the accuracy of movement. The pull buckle 36 at the bottom is engaged with the pull rod 57 of the conveying mechanism 5 to realize the power transmission between the two and complete the storage and retrieval operation of the shelf.

[0055] Working principle: The rotating motor 42 is fixed to the top of the top frame 41. Its output end is connected to the double-layer sprockets 44 at both ends through the drive rod 43. When the rotating motor 42 starts, the drive rod 43 drives the double-layer sprockets 44 to rotate synchronously. A lifting chain 45 is sleeved on the outside of the double-layer sprockets 44. One end of the lifting chain 45 is fixed to the inner side of the top of the support frame 46 through the main connecting buckle 81, and the other end is fixed to the inner side of the bottom of the abutment frame 48 through the auxiliary connecting buckle 82 after the angle of movement is changed by the corner sprocket 47 at the bottom of the column 1. When the double-layer sprockets 44 rotate, one end of the lifting chain 45 slides upward and the other end slides downward. The overall structure formed by the connecting plate 49 and the supporting frame 46 and the abutment frame 48 slides up and down outside the column 1 with the help of the moving component 7. The upper roller 72 on the inner side of the bottom of the supporting frame 46 and the bottom roller 71 on the inner side of the top of the abutment frame 48 are slidably connected to the outside of the column 1. The rolling friction reduces the movement resistance. The dustproof shell 61 on the top of the top frame 41 cooperates with the internal limiting shaft 62. The limiting shaft 62 provides rotational support for the drive rod 43 and the double-layer sprocket 44 and limits their radial displacement. The dustproof shell 61 protects the internal transmission components from dust. Finally, the frame 2 moves up and down with the supporting frame 46.

[0056] The positioning motor 52 is fixed to the top of the support frame 51. Both ends of the support frame 51 are fixed to the inner side of the frame 2. The output end of the positioning motor 52 is connected to the control sprockets 54 at both ends through the transmission rod 53. When the positioning motor 52 works, the transmission rod 53 drives the control sprockets 54 to rotate, driving the externally sleeved traction chain 55 to move. The traction chain 55 is sequentially sleeved with a tightening pulley 58 and a receiving pulley 59 to form a closed loop with the take-off pulley 510. The tightening pulley 58 tensions the chain and adjusts the tension. The receiving pulley 59 changes the direction of the chain so that it faces the column 1. The take-off pulley 510 assists the chain to complete the loop turning. The movable seat 56 fixed to the outside of the traction chain 55 moves with the chain, and the pull rod 57 rotatably connected to its inner side moves synchronously.

[0057] In the shelf mechanism 3, multiple guide rails 31 are fixed to the inner side walls of the column 1. The side of the guide rail 31 away from the frame 2 is connected to the abutment plate 32 by a thread to limit the sliding range of the shelf frame 33. The small rollers 35 at the top of the two parallel guide rails 31 are rotatably connected to the sides of the shelf frame 33, so that the shelf frame 33 can slide horizontally along the guide rails 31. The support rod 34 inside the shelf frame 33 is used to support the shelf. When the frame 2 is raised and lowered to the target shelf, the pull rod 57 moves to the vicinity of the shelf frame 33 and engages with the pull buckle 36 at the bottom. The traction chain 55 drives the pull rod 57 to pull or push the shelf frame 33 through the movable seat 56. When pulled outward, the shelf frame 33 slides along the guide rail 31 towards the frame 2 through the small rollers 35 to remove the shelf. When pushed inward, the shelf frame 33 slides to the limit position of the abutment plate 32 to complete the storage of the shelf. The positioning sensors 37 on both sides of the shelf frame 33 near the frame 2 detect the position in real time to ensure that the shelf frame 33 stops accurately.
