Description

Technical Field

[0001] This invention belongs to the field of automated storage and retrieval system technology, specifically an automated automated storage and retrieval equipment for sheet metal storage. Background Technology

[0002] Currently, after the produced sheets are packaged, they are generally stacked using forklifts. However, due to limitations in the structure of the forklifts themselves, as well as the structure and strength of the sheets, it is difficult to stack the sheets to a high height, resulting in low storage capacity and low space utilization. At the same time, due to the large number of product specifications, manual operation of forklifts makes it difficult to distinguish product types, leading to slow delivery progress or even incorrect shipments.

[0003] Due to the limited space in the warehouse and the amount of boards stacked inside, the forklifts operated by the staff move relatively slowly. When stacking and retrieving boards, it is relatively difficult for the staff to find and retrieve them, resulting in high labor costs and low efficiency.

[0004] Meanwhile, when boards are stored in an automated warehouse, the stacking height is relatively high. During storage and retrieval, the boards are easily affected by external factors, which can cause the stacked boards to become unstable and shake. In severe cases, this can lead to safety accidents such as boards tipping over, affecting the safe and stable operation of the storage equipment. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes an automated three-dimensional storage system for sheet materials. By coordinating storage racks, gantry frames, and mobile racks, the system enables automated storage of sheet materials, reducing the area occupied by the storage and facilitating storage and retrieval. Furthermore, the system utilizes telescopic columns, damping blocks, stop blocks, and baffles to ensure stable and balanced storage of the sheet materials, preventing tilting, shaking, or tipping during storage or retrieval. This ensures the safe and stable operation of the storage equipment.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an automated three-dimensional storage equipment for sheet metal storage, including a storage rack, a fixed frame installed on the storage rack, a fixed guide rail installed on the fixed frame, and a movable frame placed on the fixed frame, the movable frame being mounted on the fixed guide rail by rollers;

[0007] A gantry frame is symmetrically installed on one side of the storage rack. A lifting rod is installed on the gantry frame. A first guide column is installed at the end of the gantry frame away from the storage rack. One end of the lifting rod is slidably installed on the first guide column. A chain is installed on the other end of the lifting rod. The chain is driven by a lifting motor.

[0008] The lifting rod is equipped with a lifting guide rail, and a lifting frame is installed between the lifting rods. A fixed plate, an electric push rod, and a drive motor are installed below the lifting frame. A mounting frame is slidably installed on the fixed plate. A drive wheel is installed at one end of the mounting frame, and the other end of the mounting frame is connected to the electric push rod. The drive motor drives the drive wheel to rotate through a flexible shaft, and the drive wheel drives the moving frame to move.

[0009] The drive wheel and the surface of the movable frame that contacts the drive wheel are provided with mutually cooperating teeth and grooves. The fixed guide rail away from the gantry frame and the lifting guide rail away from the storage rack are both equipped with stop blocks.

[0010] The movable frame includes an outer frame and a contact frame. There is a height difference between the upper surface of the contact frame and the outer frame. A telescopic column is installed on the upper surface of the contact frame, and the telescopic column is flush with the upper surface of the outer frame.

[0011] Stacked plates are placed on the contact frame.

[0012] Preferably, a connecting plate is installed on the contact frame, and the telescopic column is installed on the connecting plate; the connecting plate has a groove or cavity inside, and the telescopic columns are interconnected through the connecting plate; the telescopic column is a hydraulic telescopic rod.

[0013] The telescopic column was not fully extended in its initial state.

[0014] Preferably, the contact frame is equipped with an adhesive layer, the telescopic column is installed inside the adhesive layer, the adhesive layer is made of a highly elastic rubber material, and the surface of the adhesive layer is roughened.

[0015] Preferably, a second guide column is installed inside the gantry frame, and the two ends of the lifting rod are slidably installed on the first guide column and the second guide column, respectively. The chain and the second guide column are located at the same end of the lifting rod, and the chain and the second guide column are located in the internal space of the column on the gantry frame.

[0016] Preferably, an installation block is installed inside the fixed frame, the installation block is located at the end of the fixed frame facing the gantry frame, a movable block is slidably installed inside the installation block, a spring is installed between the end of the movable block away from the gantry frame and the inner wall of the installation block, a guide slope is provided at the end of the movable block away from the gantry frame, a limit post is installed on the installation block, the lower end of the limit post contacts the guide slope, and the upper end of the limit post rises from the fixed guide rail;

[0017] A magnetic block is installed inside the end of the lifting frame near the storage rack. There is a magnetic repulsion between the magnetic block and the movable block. The magnitude of the magnetic repulsion is greater than the magnitude of the elastic force of the spring.

[0018] Preferably, a baffle plate is installed on the outer frame, and the upper surface of the baffle plate is located above the upper surface of the outer frame;

[0019] The baffle plate is located at the end of the outer frame away from the gantry.

[0020] Preferably, a damping block is installed at the end of the lifting guide rail away from the storage rack and the end of the fixed guide rail away from the gantry frame. The upper surface of the damping block is inclined, and the end of the damping block near the stop block is higher than the other end of the damping block.

[0021] The damping block is made of a rubber material with good elasticity.

[0022] Preferably, the damping block has an internal cavity filled with hydraulic oil, so that the cavity will not be completely squeezed and sealed when the damping block is compressed.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The automated three-dimensional storage equipment for sheet metal storage described in this invention enables three-dimensional storage of sheet metal by setting up storage racks, fixed racks, mobile racks, gantry racks, lifting racks, drive motors, and drive wheels, thereby reducing the area occupied by sheet metal storage. At the same time, the sheet metal can be automatically placed into or taken out of the storage racks during storage and retrieval, which facilitates the storage and retrieval of sheet metal, reduces the difficulty of finding and retrieving sheet metal, reduces labor costs, and improves the efficiency of sheet metal storage and retrieval.

[0025] 2. The automated three-dimensional storage equipment for sheet metal storage described in this invention, by setting fixed guide rails, lifting guide rails, damping blocks and blocking columns, enables the moving frame to gradually reduce its speed when moving on the fixed guide rails and lifting guide rails, avoiding sudden stops when the moving frame reaches the end of the guide rails, and avoiding or reducing the possibility of the stacked sheet metal shaking or tipping over due to sudden stops, thus ensuring the safety of storage and retrieval during the three-dimensional storage of sheet metal.

[0026] 3. The automated three-dimensional storage equipment for sheet metal storage described in this invention, by setting up an outer frame, contact frame, bonding layer, telescopic columns, and connecting plates, allows the sheet metal placed on the moving frame to be partially compressed by the telescopic columns, while the uncompressed telescopic columns position and limit the sheet metal, preventing the sheet metal from moving on the moving frame and affecting the stability of the stacked sheet metal. At the same time, since the telescopic columns are interconnected through the connecting plates, the sheet metal exerts a balanced force on all parts of the moving frame, ensuring that the stacked sheet metal is placed evenly and horizontally on the moving frame, further reducing the possibility of the sheet metal tilting, shaking, or tipping over, and ensuring the safe and stable operation of the storage equipment.

Detailed Implementation

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] like Figures 1 to 12 As shown, the automated three-dimensional storage equipment for sheet metal storage of the present invention includes a storage rack 1, a fixed frame 11 installed on the storage rack 1, a fixed guide rail 12 installed on the fixed frame 11, and a movable frame 2 placed on the fixed frame 11. The movable frame 2 is mounted on the fixed guide rail 12 by rollers 23.

[0043] A gantry frame 3 is symmetrically installed on one side of the storage rack 1. A lifting rod 32 is installed on the gantry frame 3. A first guide column 31 is installed at the end of the gantry frame 3 away from the storage rack 1. One end of the lifting rod 32 is slidably installed on the first guide column 31. A chain 321 is installed on the other end of the lifting rod 32. The chain 321 is driven by the lifting motor 33.

[0044] A lifting guide rail 351 is installed on the lifting rod 32, and a lifting frame 35 is installed between the lifting rods 32. A fixing plate 381, an electric push rod 36 and a drive motor 37 are installed below the lifting frame 35. A mounting bracket 38 is slidably installed on the fixing plate 381. A drive wheel 382 is installed at one end of the mounting bracket 38, and the other end of the mounting bracket 38 is connected to the electric push rod 36. The drive motor 37 drives the drive wheel 382 to rotate through a flexible shaft 371, and the drive wheel 382 drives the movable frame 2 to move.

[0045] The drive wheel 382 and the surface of the movable frame 2 that contacts the drive wheel 382 are provided with mutually cooperating teeth and grooves. The fixed guide rail 12 away from the gantry frame 3 and the lifting guide rail 351 away from the storage rack 1 are both equipped with stop blocks 353.

[0046] The movable frame 2 includes an outer frame 21 and a contact frame 22. There is a height difference between the contact frame 22 and the upper surface of the outer frame 21. A telescopic column 25 is installed on the upper surface of the contact frame 22, and the telescopic column 25 is flush with the upper surface of the outer frame 21.

[0047] Stacked plates are placed on the contact frame 22;

[0048] When storing the boards, the controller controls the lifting motor 33 to rotate, causing the chain 321 to rotate vertically inside the column of the gantry frame 3. This causes the lifting rod 32 and the lifting frame 35 to move up and down, aligning the lifting frame 35 with the fixed frame 11 on the storage rack 1 and the lifting guide rail 351 with the fixed guide rail 12. At the same time, sprockets are installed at the upper and lower ends inside the column of the gantry frame 3, and the chain 321 is installed on the upper and lower sprockets to ensure that the chain 321 is stably driven to rotate by the lifting motor 33.

[0049] After the lifting frame 35 and the fixed frame 11, and the lifting guide rail 351 and the fixed guide rail 12 are aligned with each other, the controller controls the electric push rod 36 to extend, so that the mounting frame 38 extends towards the storage rack 1, thereby making the drive wheel 382 on the mounting frame 38 contact with the movable frame 2 placed on the fixed frame 11. Then, the controller controls the drive motor 37 to operate, and the drive motor 37 drives the drive wheel 382 to rotate through the flexible shaft 371, thereby driving the movable frame 2 to move along the direction of the fixed guide rail 12 and the lifting guide rail 351, so that the movable frame 2 moves from the storage rack 1 to the lifting frame 35.

[0050] After the movable frame 2 reaches the lifting frame 35, the control drive motor 37 stops moving and the electric push rod 36 retracts. Then, the controller controls the lifting motor 33 to drive the lifting frame 35 and the movable frame 2 to move downwards to facilitate the placement and storage of the board material. The electric push rod 36 also drives the mounting frame 38 to retract, so as to avoid interference between the mounting frame 38 and the fixed frame 11 or other movable frames 2 on the storage rack 1 when the lifting frame 35 moves downwards.

[0051] Meanwhile, after the mobile frame 2 reaches the position below where the boards are stored or retrieved, the controller controls the lifting motor 33 to stop. Then, the operator uses a forklift to place the stacked boards onto the mobile frame 2. After that, the controller controls the lifting motor 33 to move, so that the lifting frame 35 is aligned with the fixed frame 11 that just removed the mobile frame 2. Then, the controller controls the electric push rod 36 to extend the mounting frame 38 and make contact between the drive wheel 382 and the mobile frame 2. Then, the controller controls the drive motor 37 to move, so that the mobile frame 2 is transferred from the lifting frame 35 to the fixed frame 11. After that, the controller controls the lifting frame 35 and the mounting frame 38 to return to their initial positions, thus completing the placement and storage of the boards. Similarly, when retrieving the boards, the controller controls the storage equipment to move in the reverse direction.

[0052] Meanwhile, since the boards on storage rack 1 are stacked, the height of the boards is relatively high. Since the height of the contact frame 22 on the moving rack 2 is less than the height of the outer frame 21, the stacked boards are located on the contact frame 22. After the boards are placed on the contact frame 22, the boards will compress the telescopic column 25 located below the boards on the contact frame 22. The telescopic column 25 located outside the area below the boards will not have an effect. The telescopic column 25 that is not compressed will have a limiting and positioning effect on the boards, thereby ensuring that the boards are stably placed on the moving rack 2 and stably stored in the storage equipment. This avoids the boards stored in the storage equipment from shifting or shaking due to external vibration or accidental contact, which would affect the safe and stable operation of the storage equipment. In addition, in actual application, a pallet can be set under the boards, and the stacked boards and the pallet can be packaged and fixed with cable ties.

[0053] Meanwhile, stop blocks 353 are installed at the ends of the lifting guide rail 351 and the fixed guide rail 12 that are far apart from each other, to limit and block the extreme positions of the movement of the mobile frame 2 on the lifting guide rail 351 and the fixed guide rail 12, so as to prevent the rollers 23 on the mobile frame 2 from falling off the guide rail and causing a safety accident.

[0054] In one embodiment of the present invention, a connecting plate 251 is installed on the contact frame 22, and the telescopic column 25 is installed on the connecting plate 251; the connecting plate 251 has a groove or cavity inside, and the telescopic columns 25 are interconnected through the connecting plate 251; the telescopic column 25 is a hydraulic telescopic rod.

[0055] The telescopic column 25 was not fully extended in its initial state;

[0056] Because the boards are placed onto the mobile rack 2 by forklifts operated by staff, the position of the boards on the mobile rack 2 is not fixed and changes within the allowable range. At the same time, because the boards are stacked and the quality of different boards varies, the center of gravity of the stacked boards placed on the mobile rack 2 will change. Furthermore, when the boards are stored in the storage equipment, the force exerted by the boards on the mobile rack 2 varies, affecting the stable storage of the boards and the safe and stable operation of the storage equipment.

[0057] Meanwhile, since the hydraulic telescopic rods of the telescopic columns 25 are interconnected through the connecting plate 251, when the plate exerts pressure on the telescopic columns 25 on the contact frame 22, the hydraulic pressure in each of the compressed telescopic columns 25 will be the same, so that the force exerted by the plate on the contact frame 22 is balanced. This avoids slight tilting or displacement of the plate on the contact frame 22 due to deviations in the plate's placement or uneven mass distribution, thus ensuring the stable placement of the plate on the moving frame 2, making the plate even and stable, and preventing the plate from shaking or tipping over, which could lead to safety accidents.

[0058] In one embodiment of the present invention, the contact frame 22 is provided with an adhesive layer 24, the telescopic column 25 is installed inside the adhesive layer 24, the adhesive layer 24 is made of a rubber material with good elasticity, and the surface of the adhesive layer 24 is roughened.

[0059] The adhesive layer 24 surrounds and protects the telescopic column 25, preventing it from being directly exposed to the external environment and reducing the interference and damage caused by dust and impurities in the external environment. This ensures the normal operation of the telescopic column 25. At the same time, since the telescopic column 25 is installed in the adhesive layer 24, if the telescopic column 25 is damaged or the internal hydraulic oil leaks, the hydraulic oil is sealed in the internal space of the adhesive layer 24 as much as possible, preventing the leaked hydraulic oil from dripping onto the plate and causing contamination, thus rendering the plate unusable.

[0060] In one embodiment of the present invention, a second guide column 34 is installed inside the gantry frame 3, and the two ends of the lifting rod 32 are slidably installed on the first guide column 31 and the second guide column 34 respectively. The chain 321 and the second guide column 34 are located at the same end of the lifting rod 32, and the chain 321 and the second guide column 34 are located in the internal space of the column on the gantry frame 3.

[0061] By installing the first guide column 31 and the second guide column 34 on the gantry frame 3, the lifting rod 32 is slidably mounted on the first guide column 31 and the second guide column 34, ensuring that the lifting rod 32 can move up and down smoothly and horizontally. At the same time, during the process of the moving frame 2 and the plates above it being transferred from the fixed guide rail 12 to the lifting guide rail 351, when the moving frame 2 just contacts the lifting guide rail 351, the end of the lifting rod 32 near the storage rack 1 is subjected to a large force. At this time, the first guide column 31 and the second guide column 34 stabilize and support the lifting rod 32, preventing the lifting rod 32 from tilting after being subjected to a large force, which would cause the moving frame 2 and the stacked plates to become unstable and the plates to tip over, thus ensuring the safe and stable operation of the storage equipment.

[0062] In one embodiment of the present invention, a mounting block 111 is installed inside the fixed frame 11. The mounting block 111 is located at the end of the fixed frame 11 facing the gantry frame 3. A movable block 112 is slidably installed inside the mounting block 111. A spring 114 is installed between the end of the movable block 112 away from the gantry frame 3 and the inner wall of the mounting block 111. A guide slope 113 is provided at the end of the movable block 112 away from the gantry frame 3. A limiting post 115 is installed on the mounting block 111. The lower end of the limiting post 115 contacts the guide slope 113, and the upper end of the limiting post 115 rises from the fixed guide rail 12.

[0063] A magnetic block 39 is installed in the end of the lifting frame 35 near the storage rack 1. There is a magnetic repulsion between the magnetic block 39 and the movable block 112. The magnitude of the magnetic repulsion is greater than the magnitude of the elastic force of the spring 114.

[0064] When the lifting frame 35 and the fixed frame 11 are aligned and the moving frame 2 begins to move, due to the magnetic repulsion, the movable block 112 inside the mounting block 111 will be pushed towards the storage rack 1 by the magnetic force, and the spring 114 will be compressed, causing the lower end of the limiting post 115 to move towards the lower end of the guide slope 113. That is, the part of the limiting post 115 that extends on the fixed guide rail 12 will retract downwards, so that when the moving frame 2 is transferred from the fixed guide rail 12 to the lifting guide rail 351, the limiting post 115 will not obstruct or interfere with the movement of the moving frame 2.

[0065] Meanwhile, after the boards are placed or retrieved, the lifting frame 35 returns to its initial position under the control of the controller. At this time, the lifting frame 35 is not aligned with the fixed frame 11 on the storage rack 1, so that the movable block 112 is no longer subject to magnetic repulsion. The movable block 112 moves towards the gantry 3 under the action of the spring 114 until it returns to its initial position. At the same time, after the movable block 112 returns to its initial position, the lower end of the limiting post 115 is squeezed and lifted by the guide slope 113, so that the upper end of the limiting post 115 rises from the fixed guide rail 12. The rising limiting post 115 limits and blocks the movable frame 2 placed on the fixed guide rail 12, preventing the movable frame 2 from sliding when subjected to external vibration or contact, which would cause the movable frame 2 with boards or the idle movable frame 2 to fall or slip from the end of the fixed guide rail 12 near the gantry 3, resulting in a safety accident in the storage equipment and damage to the boards.

[0066] In one embodiment of the present invention, a baffle plate 211 is installed on the outer frame 21, and the upper surface of the baffle plate 211 is located above the upper surface of the outer frame 21.

[0067] The baffle plate 211 is located at the end of the outer frame 21 away from the gantry 3;

[0068] Because the stacked boards are placed by forklifts operated by workers, the boards are prone to positional errors during placement. For example, if the workers' line of sight is blocked or their field of vision is not wide, the boards may be placed closer to or beyond the side of the mobile frame 2 away from the gantry frame 3. This can cause the boards to be unstable, wobbly, or tip over, resulting in safety accidents.

[0069] Meanwhile, a baffle plate 211 is installed on the outer frame 21 of the mobile frame 2, and the baffle plate 211 is located on the side of the mobile frame 2 away from the gantry 3. Thus, when the board is placed, the baffle plate 211 can be used to position and block the board, ensuring that the position deviation of the board on the mobile frame 2 is within the allowable range, so as to ensure the stability of the board after placement, avoid the board from tipping over or shaking during storage, and minimize the risk of safety accidents.

[0070] At the same time, when the mobile frame 2 is transferred to the lifting guide rail 351, the electric push rod 36 will retract synchronously, so that the drive wheel 382 always maintains contact with the mobile frame 2, thereby fixing the mobile frame 2 relatively on the lifting guide rail 351. This reduces or avoids the possibility of the mobile frame 2 moving due to being touched by the forklift when the forklift places the plate onto the mobile frame 2 or takes the plate from the mobile frame 2.

[0071] In one embodiment of the present invention, a damping block 352 is installed at one end of the lifting guide rail 351 away from the storage rack 1 and the fixed guide rail 12 away from the gantry frame 3. The upper surface of the damping block 352 is inclined, and the end of the damping block 352 near the stop block 353 is higher than the other end of the damping block 352.

[0072] The damping block 352 is made of a rubber material with good elasticity;

[0073] Because the stacked boards have a relatively large mass, when the moving frame 2, which holds the boards, moves along the fixed guide rail 12 or the lifting guide rail 351, the inertia of the moving frame 2 and the boards is relatively large. Therefore, when the moving frame 2 encounters the stop block 353 and stops abruptly, it can easily cause the stacked boards to shake or the storage rack 1 in the storage equipment to vibrate, affecting the safe and stable operation of the storage equipment and posing a safety hazard. Therefore, damping blocks 352 are installed on the lifting guide rail 351 and the fixed guide rail 12. When the moving frame 2 moves along the lifting guide rail 351 or the fixed guide rail 12, damping blocks 352 are installed. 2. When the movement occurs, the rollers 23 on the moving frame 2 will roll on the guide rail. As the moving frame 2 gradually approaches the end of the lifting guide rail 351 away from the storage rack 1 or the end of the fixed guide rail 12 away from the gantry frame 3, the height of the damping block 352 contacted by the rollers 23 gradually increases, so that the damping of the rollers 23 gradually increases, thereby reducing the speed of the moving frame 2 and gradually reducing the moving speed of the moving frame 2. This avoids the moving frame 2 from stopping suddenly during movement, as well as the impact and damage caused by the sudden stop, ensuring the stability and safety of the plate and avoiding safety accidents.

[0074] In one embodiment of the present invention, the damping block 352 has a cavity inside, which is filled with hydraulic oil, so that the cavity will not be completely squeezed and closed when the damping block 352 is compressed.

[0075] When the damping block 352 is squeezed by the roller 23, and the roller 23 moves from one end of the damping block 352 to the other end, the hydraulic oil inside the damping block 352 flows. During this process, the hydraulic oil in the unsqueezed end of the damping block 352 flows to the squeezed end. Since the flow speed of the hydraulic oil is limited, that is, the size of the cavity at the squeezing point of the roller 23 is reduced, the damping block 352 is supported by the internal hydraulic oil and its hardness is increased. This avoids the damping block 352 being too hard, which would make the roller 23 easily squeeze and deform the damping block 352, resulting in poor blocking and deceleration effect of the damping block 352 against the roller 23.

[0076] The specific workflow is as follows:

[0077] When storing the boards, the controller controls the lifting motor 33 to rotate the chain 321 in the vertical direction inside the column of the gantry frame 3, so that the lifting rod 32 and the lifting frame 35 move up and down, so that the lifting frame 35 is aligned with the fixed frame 11 on the storage rack 1 and the lifting guide rail 351 is aligned with the fixed guide rail 12.

[0078] The controller controls the electric push rod 36 to extend, so that the drive wheel 382 on the mounting bracket 38 comes into contact with the movable frame 2 placed on the fixed bracket 11. Then, the controller controls the drive motor 37 to operate. The drive motor 37 drives the drive wheel 382 to rotate through the flexible shaft 371, thereby driving the movable frame 2 to move along the direction of the fixed guide rail 12 and the lifting guide rail 351, so that the movable frame 2 moves from the storage rack 1 to the lifting frame 35.

[0079] After the movable frame 2 reaches the lifting frame 35, the control drive motor 37 stops moving and the electric push rod 36 retracts. Then, the controller controls the lifting motor 33 to drive the lifting frame 35 and the movable frame 2 to move downwards, and the electric push rod 36 drives the mounting frame 38 to retract.

[0080] Meanwhile, after the mobile frame 2 reaches the position below where the boards are stored or retrieved, the controller controls the lifting motor 33 to stop. Then, the staff operates a forklift to place the stacked boards onto the mobile frame 2. After that, the controller controls the lifting motor 33 to move, so that the lifting frame 35 is aligned with the fixed frame 11 that just removed the mobile frame 2. Then, the controller controls the electric push rod 36 to drive the mounting frame 38 to extend and the drive wheel 382 to contact the mobile frame 2. Then, the controller controls the drive motor 37 to move, so that the mobile frame 2 is transferred from the lifting frame 35 to the fixed frame 11. After that, the controller controls the lifting frame 35 and the mounting frame 38 to return to the initial position, thus completing the placement and storage of the boards.

[0081] Meanwhile, after the plate is placed on the contact frame 22, the plate will squeeze the telescopic column 25 located below the plate on the contact frame 22, and will not have any effect on the telescopic column 25 located outside the area below the plate. This allows the unsqueezed telescopic column 25 to limit and position the plate. In addition, in actual application, a tray can be set under the plate, and the stacked plates and the tray can be packaged and fixed with cable ties.

[0082] Meanwhile, stop blocks 353 are installed at the ends of the lifting guide rail 351 and the fixed guide rail 12 that are far apart from each other, so as to limit and block the extreme positions of the movement of the mobile frame 2 on the lifting guide rail 351 and the fixed guide rail 12.

[0083] Meanwhile, since the hydraulic telescopic rods of the telescopic columns 25 and the telescopic columns 25 are interconnected through the connecting plate 251, when the plate exerts pressure on the telescopic columns 25 on the contact frame 22, the hydraulic pressure in each of the compressed telescopic columns 25 will be the same, so that the force exerted by the plate on the contact frame 22 is balanced, and the plate will not be slightly tilted or offset on the contact frame 22 due to deviation in the placement position or uneven mass distribution.

[0084] The telescopic column 25 is surrounded and protected by the bonding layer 24 to prevent the telescopic column 25 from being directly exposed to the external environment. At the same time, since the telescopic column 25 is installed in the bonding layer 24, when the telescopic column 25 is damaged or the internal hydraulic oil leaks, the hydraulic oil is sealed in the internal space of the bonding layer 24 as much as possible to prevent the leaked hydraulic oil from dripping onto the plate.

[0085] During the process of transferring the movable frame 2 and the plate above it from the fixed guide rail 12 to the lifting guide rail 351, when the movable frame 2 just contacts the lifting guide rail 351, the end of the lifting rod 32 near the storage rack 1 is subjected to a large force. At this time, the lifting rod 32 is stabilized and supported by the first guide column 31 and the second guide column 34 to prevent the lifting rod 32 from tilting after being subjected to a large force.

[0086] When the lifting frame 35 and the fixed frame 11 are aligned and the moving frame 2 begins to move, due to the magnetic repulsion, the movable block 112 inside the mounting block 111 will be pushed towards the storage rack 1 by the magnetic force, and the spring 114 will be compressed, causing the lower end of the limiting post 115 to move towards the lower end of the guide slope 113. That is, the part of the limiting post 115 that extends on the fixed guide rail 12 will retract downwards, and the limiting post 115 will not obstruct or interfere with the movement of the moving frame 2.

[0087] Meanwhile, after the plates are placed or taken out, the lifting frame 35 returns to its initial position under the control of the controller. At this time, the lifting frame 35 is not aligned with the fixed frame 11 on the storage rack 1, so that the movable block 112 is no longer subject to magnetic repulsion. The movable block 112 moves towards the gantry frame 3 under the action of the spring 114 until the movable block 112 returns to its initial position. At the same time, after the movable block 112 returns to its initial position, the lower end of the limiting post 115 will be squeezed and lifted by the guide slope 113, so that the upper end of the limiting post 115 rises from the fixed guide rail 12 to limit and block the movable frame 2 placed on the fixed guide rail 12.

[0088] Meanwhile, a baffle plate 211 is provided on the outer frame 21 of the mobile frame 2, and the baffle plate 211 is located on the side of the mobile frame 2 away from the gantry 3. When the plate is placed, the baffle plate 211 can be used to position and block the plate.

[0089] At the same time, when the mobile frame 2 is transferred to the lifting guide rail 351, the electric push rod 36 will retract synchronously, so that the drive wheel 382 always maintains contact with the mobile frame 2, thereby fixing the mobile frame 2 relatively on the lifting guide rail 351. This reduces or avoids the possibility of the mobile frame 2 moving due to being touched by the forklift when the forklift places the plate onto the mobile frame 2 or takes the plate from the mobile frame 2.

[0090] Damping blocks 352 are installed on the lifting guide rail 351 and the fixed guide rail 12. When the moving frame 2 moves along the lifting guide rail 351 or the fixed guide rail 12, the rollers 23 on the moving frame 2 will roll on the guide rail. As the moving frame 2 gradually approaches the end of the lifting guide rail 351 away from the storage rack 1 or the end of the fixed guide rail 12 away from the gantry 3, the height of the damping block 352 contacted by the rollers 23 gradually increases, so that the damping of the rollers 23 gradually increases, thereby reducing the speed of the moving frame 2 and making the moving speed of the moving frame 2 gradually decrease, so as to avoid the moving frame 2 from stopping suddenly during movement.

[0091] When the damping block 352 is squeezed by the roller 23, and the roller 23 moves from one end of the damping block 352 to the other end, the hydraulic oil inside the damping block 352 flows. During this process, the hydraulic oil in the unsqueezed end of the damping block 352 flows to the squeezed end. Since the flow speed of the hydraulic oil is limited, that is, the size of the cavity at the squeezing point of the roller 23 is reduced, the damping block 352 is supported by the internal hydraulic oil and its hardness is increased. This prevents the damping block 352 from being too hard and easily squeezed and deformed by the roller 23, resulting in poor blocking and deceleration effect of the damping block 352 against the roller 23.
