Description

Technical Field

[0001] This invention relates to the field of automated warehouse technology, and in particular to an intelligent automated warehouse conveyor anti-fall pallet device. Background Technology

[0002] Automated storage and retrieval systems (AS / RS), also known as high-bay warehouses, utilize multi-layered or even dozens of layers of racking to store goods, significantly improving space utilization. Their space utilization rate is typically 2 to 5 times that of ordinary flat warehouses. They employ automated equipment such as stacker cranes, shuttle cars, and pallet conveyors, in conjunction with warehouse management and control systems, to achieve automated storage and retrieval and intelligent management of goods.

[0003] Currently, the retrieval and placement of goods in automated warehouses mainly rely on the lifting and lowering of conveyor pallets. In actual use, the existing pallets need to be transferred back and forth between different shelves, which requires the pallets to undergo a large number of start-stop processes. Due to the inertia of motion, the pallets are prone to shaking during the start-stop process, which poses a risk of them falling off. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent automated warehouse conveyor anti-fall pallet device, which aims to solve the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An intelligent automated warehouse conveyor anti-fall pallet device includes a movable base that can move linearly along a warehouse track. Uprights are fixed at both ends of the top of the movable base. Lifting supports are slidably mounted on the side walls of the uprights. A lifting assembly for driving the lifting supports to rise and fall at a uniform speed is provided on one side of the uprights. A conveyor pallet is mounted on the upper end of the lifting supports. The conveyor pallet includes a pallet body that is horizontally slidably mounted within a pallet seat. A set of metal positioning posts is fixed at both ends of the bottom of the pallet seat. A connecting block is fixed between each set of metal positioning posts. A bottom shell is fixed at the bottom of the lifting supports. Bar magnets are fixed at both ends inside the bottom shell, and a ring magnet is fixed in the center of the bottom shell. In the energized state, the bar magnets electromagnetically lock the metal positioning posts; in the de-energized state, the ring magnet mechanically locks the connecting blocks.

[0007] As a further aspect of the present invention: the lifting bracket is provided with mounting holes through which the metal positioning column and the connecting block pass.

[0008] As a further embodiment of the present invention: the top of the bottom shell is fixedly installed on the bottom of the lifting bracket by a fixing plate, the two ends of the fixing plate are fixedly provided with support frames, the bottom center of the fixing plate is fixedly provided with a fixing rod, the bottom of the bottom shell is provided with a positioning groove corresponding to the metal positioning column, and the bar magnet is fixedly installed on the bottom of the positioning groove.

[0009] As a further embodiment of the present invention: a metal collar is slidably mounted on the fixing rod, the metal collar is located directly above the annular magnet, a connecting bracket is provided extending downward from the bottom end of the metal collar, the connecting bracket passes through the annular magnet and extends out from the bottom of the bottom shell, and a pull ring is fixedly provided at the bottom of the connecting bracket.

[0010] As a further embodiment of the present invention: a sliding rod is slidably installed inside the support frame, and connecting rods are symmetrically and rotatably installed at both ends of the metal collar. The end of the connecting rod is rotatably connected to one end of the corresponding sliding rod, and a limiting block is fixedly provided at the other end of the sliding rod. A limiting hole corresponding to the limiting block is provided on the connecting block, and a return spring is provided between the limiting block and the support frame.

[0011] As a further aspect of the present invention: a power supply module is provided inside the bottom shell, and the power supply module is electrically connected to the bar magnet and the ring magnet respectively.

[0012] As a further embodiment of the present invention: the lifting assembly includes a cylinder, a fixed pulley, and a movable pulley. The cylinder is fixedly mounted on the movable base, the fixed pulley is rotatably mounted on the top of the upright, and the movable pulley is rotatably mounted inside the rotating seat. The output end of the cylinder is fixedly connected to the bottom end of the rotating seat. A chain is provided between the fixed pulley and the movable pulley. One end of the chain is fixedly connected to the top of the upright, and the other end of the chain passes through the movable pulley and the fixed pulley in sequence before being fixedly connected to the lifting bracket.

[0013] As a further aspect of the present invention: a lifting rail is vertically provided on the side wall of the support frame, and the lifting bracket is slidably installed on the lifting rail via a sliding seat. A set of buffers and a set of limiters are fixedly installed at both the upper and lower ends of the lifting rail.

[0014] As a further embodiment of the present invention: the mobile base is rotatably mounted with wheels at both ends, the wheels are adapted to be rolled on the upper end of the warehouse track, and a drive motor is fixedly mounted on one side of the mobile base, the output end of the drive motor being connected to the wheels.

[0015] The beneficial effects of this invention are:

[0016] (1) By setting metal positioning posts, connecting blocks, bar magnets and ring magnets, when the conveying pallet is installed on the lifting bracket, the metal positioning posts and connecting blocks will pass through the lifting bracket and extend into the bottom shell. At this time, the power supply module controls the bar magnets and ring magnets to be energized. When energized, the bar magnets generate electromagnetic attraction and firmly attract the metal positioning posts, thereby limiting and fixing the position of the conveying pallet. When there is a sudden power failure, the ring magnets lose their magnetic attraction and mechanically lock the connecting blocks through mechanical transmission. In the event of a power failure, the connecting blocks are limited and fixed by pure mechanical transmission, thereby effectively ensuring the stability of the conveying pallet during the lifting and conveying process and avoiding the risk of the conveying pallet falling off in the event of a sudden power failure.

[0017] (2) When the power is off, the ring magnet loses its magnetic attraction. At this time, the limit blocks at both ends will be quickly inserted into the corresponding limit holes under the pushing force of the return spring, thereby limiting and fixing the connecting block, ensuring that the tray seat will not fall off even when the power is off. When the tray seat needs to be disassembled, the metal collar is pulled down by the pull ring when the power is off. The metal collar will drive the limit block to disengage from the limit hole to unlock, making it convenient for the tray seat to be quickly disassembled and assembled. The operation is quick and simple, and it is highly practical. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 As shown, this invention is an intelligent automated warehouse conveying anti-fall pallet device, including a movable base 1, which can move linearly along the warehouse track 2. Both ends of the top of the movable base 1 are fixedly provided with uprights 3. A lifting bracket 5 is slidably installed on the side wall of the uprights 3. A lifting assembly 4 for driving the lifting bracket 5 to rise and fall at a uniform speed is provided on one side of the uprights 3. A conveying pallet 6 is installed on the upper end of the lifting bracket 5. The conveying pallet 6 includes a pallet body 601, which is horizontally slidably installed in a pallet seat 602. Both ends of the bottom of the pallet seat 602 are fixedly provided with a set of metal positioning posts 603. A connecting block 604 is fixed between each set of metal positioning posts 603. A bottom shell 7 is fixedly provided at the bottom of the lifting bracket 5. Both ends of the bottom shell 7 are fixedly provided with bar magnets 703, and a ring magnet 704 is fixedly provided in the center of the bottom shell 7. In the energized state, the bar magnets 703 electromagnetically lock the metal positioning posts 603, and in the de-energized state, the ring magnet 704 mechanically locks the connecting block 604.

[0029] Specifically, by setting up a metal positioning post 603, a connecting block 604, a bar magnet 703, and a ring magnet 704, when the conveyor pallet 6 is installed on the lifting bracket 5, the metal positioning post 603 and the connecting block 604 will pass through the lifting bracket 5 and extend into the bottom shell 7. At this time, the control power supply module energizes the bar magnet 703 and the ring magnet 704. In the energized state, the bar magnet 703 generates electromagnetic attraction and firmly attracts the metal positioning post 603, thereby limiting and fixing the position of the conveyor pallet 6. When a sudden power failure occurs, the ring magnet 704 loses its magnetic attraction and mechanically locks the connecting block 604 through mechanical transmission. This allows the connecting block 604 to be limited and fixed by pure mechanical transmission in the event of a power failure, thereby effectively ensuring the stability of the conveyor pallet 6 during the lifting and conveying process and avoiding the risk of the conveyor pallet 6 falling off in the event of a sudden power failure.

[0030] like Figure 3 and Figure 4 As shown, the lifting bracket 5 has a through mounting hole 501 for the metal positioning column 603 and the connecting block 604 to pass through.

[0031] like Figure 5 and Figure 6 As shown, the top of the bottom shell 7 is fixedly installed on the bottom of the lifting bracket 5 by a fixing plate 701. Support frames 7011 are fixed at both ends of the fixing plate 701, and a fixing rod 7012 is fixed in the center of the bottom of the fixing plate 701. The bottom of the bottom shell 7 is provided with a positioning groove 702 corresponding to the metal positioning column 603, and a bar magnet 703 is fixedly installed at the bottom of the positioning groove 702.

[0032] Specifically, when installing the pallet seat 602, the metal positioning post 603 passes through the mounting hole 501 on the lifting bracket 5 and extends into the corresponding positioning groove 702. By utilizing the limiting constraint effect of the mounting hole 501 and the positioning groove 702, a horizontal movement constraint can be applied to the pallet seat 602. When the bar magnet 703 is energized, the metal positioning post 603 is firmly attracted, thereby applying a vertical movement constraint to the pallet seat 602, thus ensuring that the pallet seat 602 can be stably fixed on the lifting bracket 5 without moving.

[0033] like Figure 6 and Figure 7 As shown, a metal collar 705 is slidably mounted on the fixed rod 7012. The metal collar 705 is located directly above the annular magnet 704. A connecting bracket 7051 extends downward from the bottom end of the metal collar 705. The connecting bracket 7051 passes through the annular magnet 704 and protrudes from the bottom of the bottom shell 7. A pull ring 707 is fixed at the bottom of the connecting bracket 7051.

[0034] Furthermore, a slide rod 706 is slidably installed inside the support frame 7011, and a connecting rod 7052 is symmetrically and rotatably installed at both ends of the metal collar 705. The end of the connecting rod 7052 is rotatably connected to one end of the corresponding slide rod 706, and a limiting block 7061 is fixedly provided at the other end of the slide rod 706. A limiting hole 6041 corresponding to the limiting block 7061 is provided on the connecting block 604, and a return spring 7062 is provided between the limiting block 7061 and the support frame 7011.

[0035] Specifically, when energized, the bar magnet 703 electromagnetically locks the metal positioning post 603. At this time, the ring magnet 704 also magnetically attracts the metal collar 705, causing the metal collar 705 to slide downwards along the fixing rod 7012. The metal collar 705 then drives the sliding rods 706 at both ends to retract inwards via the connecting rod 7052. The limiting block 7061 disengages from the corresponding limiting hole 6041 and presses the return spring 7062. When de-energized, the ring magnet 704 loses its magnetic attraction. In this process, the limiting blocks 7061 at both ends will quickly insert into the corresponding limiting holes 6041 under the pushing force of the return spring 7062, thereby limiting and fixing the connecting block 604. This ensures that the tray seat 602 will not detach and fall even when the power is off. During this process, the support frame 7011 can limit and guide the slide rod 706, allowing the limiting block 7061 to move linearly in the correct direction, ensuring that the limiting block 7061 and the limiting hole 6041 can be smoothly engaged. When it is necessary to disassemble the tray seat 602, the metal collar 705 can be pulled down by the pull ring 707 in the power-off state. The metal collar 705 will drive the limiting block 7061 to disengage from the limiting hole 6041 to unlock it, facilitating quick disassembly and assembly of the tray seat 602. The operation is quick, simple, and highly practical.

[0036] In this embodiment, a power supply module (not shown in the figure) is provided inside the bottom shell 7. The power supply module is electrically connected to the bar magnet 703 and the ring magnet 704 respectively. The power supply module includes a power source and an on / off switch. The power source provides power to the bar magnet 703 and the ring magnet 704, while the on / off switch is used to control the on / off state of the connected circuit. The above control principle and circuit arrangement are known in the prior art and will not be described in detail here.

[0037] like Figure 1 and Figure 2As shown, the lifting assembly 4 includes a cylinder 401, a fixed pulley 403, and a movable pulley 402. The cylinder 401 is fixedly mounted on the movable base 1. The fixed pulley 403 is rotatably mounted on the top of the upright 3. The movable pulley 402 is rotatably mounted inside the rotating seat. The output end of the cylinder 401 is fixedly connected to the bottom end of the rotating seat. A chain 404 is provided between the fixed pulley 403 and the movable pulley 402. One end of the chain 404 is fixedly connected to the top of the upright 3. The other end of the chain 404 passes through the movable pulley 402 and the fixed pulley 403 in sequence and is fixedly connected to the lifting bracket 5.

[0038] Specifically, by setting up the lifting component 4, the cylinder 401 drives the pulley 402 to lift at a constant speed, which in turn drives the lifting bracket 5 to move at a constant speed through the chain belt 404. At the same time, the pulley lifting structure can effectively save effort, so that the cylinder 401 can lift the heavy objects on the lifting bracket 5 with less power.

[0039] like Figure 2 As shown, a lifting rail 301 is vertically installed on the side wall of the support frame 3. The lifting bracket 5 is slidably installed on the lifting rail 301 through a sliding seat. A set of buffers 302 and a set of limiters 303 are fixedly installed at both the upper and lower ends of the lifting rail 301.

[0040] The buffer 302 is used to absorb energy and slow down the lifting support 5 when it moves to the extreme positions at both ends, effectively reducing the impact of the movement. The limiter 303 is used to block and interfere with the lifting support 5, thereby effectively limiting the movement stroke of the lifting support 5 on the lifting track 301.

[0041] like Figure 1 As shown, the mobile base 1 has rotatably mounted wheels 102 at both ends. The wheels 102 are adapted to roll on the upper end of the warehouse track 2. A drive motor 101 is fixed on one side of the mobile base 1, and the output end of the drive motor 101 is connected to the wheels 102.

[0042] The working principle of this invention is as follows: Figures 1-7As shown, during use, the movable base 1 moves along the warehouse track 2 to adjust the position of the conveyor pallet 6. At the same time, the lifting component 4 drives the conveyor pallet 6 to move up and down along the lifting track 301 to adjust its height, so that the conveyor pallet 6 can be loaded and unloaded in different shelves of the automated warehouse. During the lifting and conveying process, when the power is on, the bar magnet 703 generates electromagnetic attraction and firmly attracts the metal positioning post 603, thereby limiting and fixing the position of the conveyor pallet 6. When a power failure occurs, the ring magnet 704 loses its magnetic attraction. At this time, the limiting blocks 7061 at both ends will be quickly inserted into the corresponding limiting holes 6041 under the pushing force of the return spring 7062, thereby limiting and fixing the connecting block 604, so that the pallet seat 602 will not fall off even when the power is off. When the tray seat 602 needs to be disassembled, the metal collar 705 is pulled down by the pull ring 707 while the power is off. The metal collar 705 will drive the limit block 7061 to disengage from the limit hole 6041 to unlock, which facilitates the quick disassembly and assembly of the tray seat 602. The operation is quick and simple.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
