Description

Technical Field

[0001] This invention relates to the field of automated warehouse technology, and in particular to an automated warehouse that facilitates the storage of warning signs of various shapes. Background Technology

[0002] The production process of warning signs requires the use of automated warehouses for stacking and storage to save space.

[0003] In automated warehouses, it is often necessary to lift low-level stacks of warning signs to high-level storage compartments. This cross-level transfer process must be completed by a lifting mechanism, which typically consists of a motor, sprockets, chains, a frame, and a rack. The rack is slidably connected to the frame and is driven by a motor to move the rack up and down.

[0004] However, most of the lifting mechanisms in existing automated warehouses lack protective structures. After prolonged use, chain breakage or detachment of the chain from the lifting frame can easily occur, causing the racks to fall. Falling racks not only damage the goods on the racks but also pose safety hazards to warehouse staff. Furthermore, breakage and other issues are difficult to detect in advance, affecting the efficiency of the automated warehouse.

[0005] Therefore, it is necessary to propose an automated warehouse that can easily store warning signs of various shapes to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated warehouse that facilitates the storage of warning signs of various shapes, in order to solve the problem that most of the lifting mechanisms in existing automated warehouses lack protective structures. After long-term use, chain breakage or detachment of the chain from the lifting frame can easily occur, leading to the rack falling. The falling rack not only damages the goods on the rack but also poses a safety hazard to warehouse staff. Furthermore, breakage and other such situations are difficult to detect in advance, affecting the efficiency of the automated warehouse.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a three-dimensional warehouse that facilitates the storage of warning signs of various shapes, comprising a warehouse floor, a lifting device, and a shelf assembly, wherein the lifting device and the shelf assembly are both located on the warehouse floor;

[0008] The lifting device includes a guide frame, on which a load rack that reciprocates along its height direction is slidably mounted. A fixed plate is installed at the bottom of the load rack, and a fixed shaft is fixed on the fixed plate. A rotating plate rotates on the fixed shaft, and a sliding channel is opened on the rotating plate. A U-shaped frame is slidably mounted inside the sliding channel. One end of the U-shaped frame inside the sliding channel is inclined, and the top end is inclined away from the fixed plate. A torsion spring is fitted on the fixed shaft.

[0009] The side of the fixed plate is provided with multiple support plates evenly distributed along the height direction of the guide frame. The horizontal height of the support plates is fixed. The support plates can be in the same longitudinal plane as the fixed plate or staggered. The top of the support plate is provided with a top rod that abuts against the inclined surface of the U-shaped frame.

[0010] Preferably, the end of the rotating plate near the fixed plate includes an arc portion and a right-angle portion, wherein the arc portion is located below the right-angle portion.

[0011] Preferably, the top of the tray has a top groove, the bottom end of the top rod is fixedly connected to the bottom of the top groove, and a first spring is fitted on the outside of the top rod, the bottom end of the first spring being fixedly connected to the bottom of the top groove.

[0012] Preferably, a pressure plate is fixedly connected to the bottom end of the sliding channel, the pressure plate abuts against the first spring, and a through groove is provided on the pressure plate for inserting a top rod.

[0013] Preferably, the upper and lower ends of the U-shaped frame are fixedly connected with limit rods, and the limit rods are attached to the rotating plate.

[0014] Preferably, a crossbar is fixedly connected to the inner wall of the U-shaped frame, a first hole is provided on the fixed shaft, a second hole is provided on the rotating plate, and a third hole is provided on the fixed plate, and the first hole, the second hole, and the third hole are connected in sequence to allow the crossbar to be inserted.

[0015] Preferably, the guide frame has a circular groove, a slide rod is slidably arranged inside the circular groove, a vertical bar is fixedly connected to the slide rod, the support plate is fixedly connected to the vertical bar, an electric push rod is fixedly installed on the guide frame, and the vertical bar is fixedly connected to the telescopic end of the electric push rod.

[0016] Preferably, a second spring is provided inside the sliding channel, with one end of the second spring fixedly connected to the inner wall of the sliding channel and the other end of the second spring fixedly connected to the U-shaped frame.

[0017] Preferably, a top column is fixedly connected to the top of the guide frame, a guide wheel is installed on the top column, a winch is installed on the guide frame, a pull rope is wound on the guide wheel, one end of the pull rope is connected to the load rack, and the other end of the pull rope is connected to the winch.

[0018] Preferably, the shelving assembly includes small-cell shelving and large-cell shelving.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. This invention achieves emergency braking by setting up structures such as fixed plates, rotating plates, top rods and U-shaped frames, protecting goods, avoiding safety hazards, and not affecting the vertical movement of the racks. At the same time, the rotating plates and fixed plates can be connected into a whole to improve the utilization efficiency of the automated warehouse.

[0021] 2. By setting up structures such as U-shaped frames and top rods, and utilizing the movement of the rotating plate, the rotating plate and the fixed plate are connected into a whole to ensure support strength and improve fall prevention efficiency, thereby ensuring the safety performance of the automated warehouse.

[0022] 3. By setting up structures such as the first spring, pressure plate, and through groove, the top rod, pressure plate, and through groove cooperate to connect the rotating plate and support plate into a whole, ensuring the stability of the support;

[0023] 4. The pressure plate squeezes the first spring to retract, and the first spring retracts into the top groove. The first spring relieves the force and buffers the impact of the fall.

[0024] 5. The push rod, pressure plate, and through groove cooperate to guide the first spring, ensuring stable contraction of the first spring;

[0025] 6. The pressure plate limits the U-shaped frame, so that when the fixed plate and rotating plate move from top to bottom, the top of the top rod can stably contact the inclined surface of the U-shaped frame, instead of directly abutting the bottom of the U-shaped frame.

[0026] 7. By setting up structures such as crossbars, first hole section, second hole section and third hole section, and utilizing the movement of the U-shaped frame, the crossbars are inserted into the first hole section, second hole section and third hole section in sequence, and the internal and external limiting are combined to further ensure the support strength;

[0027] 8. By setting up structures such as right-angle sections, U-shaped frames, crossbars, and top bars, four-fold limiting is achieved to ensure the limiting effect and support stability. Attached Figure Description

[0041] This invention provides, for example Figures 1-12 The illustrated automated warehouse is a type of warehouse that facilitates the storage of warning signs of various shapes. It includes a warehouse floor 1, a lifting device 2, and a rack assembly. The lifting device 2 and the rack assembly are both located on the warehouse floor 1, which is a monolithic concrete floor.

[0042] The shelving components include small grid shelving 3 and large grid shelving 4, which are arranged side by side along the longitudinal direction of the warehouse, with a lifting channel reserved in the middle for the lifting device 2. By combining the "high density, small unit" of small grid shelving 3 with the "large capacity, wide unit" of large grid shelving 4, it can adapt to the diverse sizes and stacking methods of triangular, round, rectangular and combined irregular-shaped warning signs, thereby improving the warehouse's adaptability to multiple specifications and batches of warning signs and its space utilization.

[0043] In a specific configuration, the lifting device 2 includes a guide frame 6, a movable frame 5 at the bottom of the guide frame 6, and casters at the four corners of the bottom of the movable frame 5. The casters are equipped with brakes to facilitate the movement and positioning of the lifting device 2. A carrying rack 8 is slidably mounted on the guide frame 6. The carrying rack 8 can move back and forth along the height direction of the guide frame 6, and rollers are mounted on the carrying rack 8. The rollers fit against the guide frame 6 to ensure the smooth up and down sliding of the carrying rack 8.

[0044] A top column 7 is fixedly connected to the top of the guide frame 6. A guide wheel 29 is installed on the top column 7. A winch 31 is installed on the guide frame 6. A pull rope 30 is wound around the guide wheel 29. One end of the pull rope 30 is connected to the load rack 8, and the other end of the pull rope 30 is connected to the winch 31. The winch 31 is connected to the factory's power supply.

[0045] When the winch 31 rotates forward, it winds up the pull rope 30, causing the rack 8 to move upward along the height direction of the guide frame 6, and the warning signs and goods on the rack 8 move upward; when the winch 31 rotates in reverse, the pull rope 30 is released, and the rack 8 moves downward along the height direction of the guide frame 6 by its own weight, and the warning signs and goods on the rack 8 move downward.

[0046] Considering the lack of protective structure on the lifting device 2, after prolonged and high-frequency use, situations such as the pull rope 30 breaking or the pull rope 30 detaching from the connection point with the rack 8 may occur, posing safety hazards and affecting the efficiency of the automated warehouse. To improve the efficiency of the automated warehouse, a fixing plate 9 is installed at the bottom of the rack 8, and two fixing plates 9 can be provided. The two fixing plates 9 are distributed on both sides of the bottom of the rack 8, and a fixing shaft 10 is fixed at the far end of each fixing plate 9. A rotating plate 11 rotates on the fixing shaft 10, and a torsion spring 28 is fitted on the fixing shaft 10. One end of the torsion spring 28 is fixedly connected to the rotating plate 11, and the other end of the torsion spring 28 is fixedly connected to the fixing shaft 10. When the rotating plate 11 is not subjected to other external forces, it remains horizontal due to the elastic support force of the torsion spring 28 (refer to...). Figure 11 ).

[0047] To control the flipping direction of the rotating plate 11, the end of the rotating plate 11 near the fixed plate 9 includes an arc portion 12 and a right-angle portion 13, wherein the arc portion 12 is located below the right-angle portion 13.

[0048] Reference Figure 11 As shown, when the rotating plate 11 is in a horizontal state, if the end of the rotating plate 11 away from the fixed plate 9 is subjected to a downward squeezing force, the rotating plate 11 can flip downwards, and after the squeezing force is lost, the restoring force of the torsion spring 28 causes the rotating plate 11 to return to a horizontal state; if the end of the rotating plate 11 away from the fixed plate 9 is subjected to an upward squeezing force, the right angle part 13 directly abuts against the rotating plate 11, and the rotating plate 11 will not flip upwards.

[0049] The curved section 12 and the right-angle section 13 are provided to control the flipping direction of the rotating plate 11.

[0050] To limit the movement of the rack 8 by means of the fixing plate 9, multiple support plates 21 are provided on the side of the fixing plate 9. The multiple support plates 21 are evenly distributed along the height direction of the guide frame 6. A circular groove 35 is provided on the guide frame 6. A slide rod 34 is slidably arranged inside the circular groove 35. A vertical bar 32 is fixedly connected to the slide rod 34. The vertical bar 32 is distributed along the height direction of the guide frame 6. The support plates 21 are fixedly connected to the vertical bar 32.

[0051] The vertical bar 32 moves along the axial direction of the fixed shaft 10, and the slide bar 34 slides adaptively inside the circular groove 35, so that the pallet 21 can be moved at a fixed horizontal height, and multiple pallets 21 are controlled synchronously.

[0052] An electric push rod 33 is fixedly installed on the guide frame 6. A vertical bar 32 is fixedly connected to the telescopic end of the electric push rod 33. The electric push rod 33 is connected to the power supply of the warehouse.

[0053] In actual use, the extension end of the control electric push rod 33 is retracted, which drives the slide rod 34 to retract into the circular groove 35, so that the support plate 21 and the fixed plate 9 are in the same longitudinal plane (see reference). Figure 8 That is, when the rotating plate 11 moves up and down, it can contact the support plate 21; the extension end of the control electric push rod 33 extends, driving the slide rod 34 to slide outward from the circular groove 35, so that the support plate 21 is misaligned with the fixed plate 9, that is, the rotating plate 11 will not contact the support plate 21 when it moves up and down.

[0054] Furthermore, rollers or other structures can be installed at the bottom corners of the pallet 21, and wear-resistant pads or other structures can be installed at the contact points between the rotating plate 11 and the pallet 21 to reduce wear. Adjustments can be made according to specific usage conditions.

[0055] In addition, the vertical bar 32, the sliding bar 34 and other structures are made of high-strength materials, such as stainless steel, to ensure the support strength. Multiple sets of sliding bars 34 and circular grooves 35 can be set, and multiple sliding bars 34 are connected to the vertical bar 32 to ensure the strength of use.

[0056] Specifically, before the goods are lifted, the telescopic end of the control electric push rod 33 is retracted, which drives the slide rod 34 to retract into the circular groove 35, so that the pallet 21 can be in the same longitudinal plane as the fixed plate 9, that is, the rotating plate 11 can contact the pallet 21 when it moves up and down, and prepare for protection.

[0057] Using a winch 31, the rack 8 is moved upward along the height of the guide frame 6, and the goods move upward. The fixed plate 9 and the rotating plate 11 move upward synchronously. The rotating plate 11 starts to move upward from a horizontal position. When the top of the rotating plate 11 away from the fixed plate 9 contacts the bottom corner of the pallet 21, the rotating plate 11 can adaptively flip downward around the fixed shaft 10 as the rack 8 continues to move upward. When the rotating plate 11 loses contact with the pallet 21, it returns to a horizontal position under the restoring force of the torsion spring 28, without affecting the upward movement of the rack 8. The rotating plate 11 then cooperates with the other pallets 21 in sequence, making contact, flipping, losing contact, and then returning to its horizontal position.

[0058] During the ascent, there are goods on the rack 8, which have a large load and a high risk of falling. Therefore, the rotating plate 11 needs to contact multiple pallets 21 one by one to be ready for emergency and to achieve a rapid response in case of emergencies.

[0059] If the pull rope 30 breaks during the upward movement of the rack 8, the rack 8 and the goods will fall downward. Since the rotating plate 11 is in a horizontal state and cannot swing upward, when the rotating plate 11 contacts the nearest support plate 21 below it, the rotating plate 11 and the fixed plate 9 will be unable to continue to move downward, achieving a braking effect. The rack 8 and the goods will stop falling downward, protecting the goods and avoiding safety hazards.

[0060] After the goods are placed on the small grid shelf 3 or large grid shelf 4 by the operator, before the load rack 8 moves downward, the telescopic end of the electric push rod 33 is extended, which drives the slide rod 34 to slide outward from the circular groove 35, so that the pallet 21 is misaligned with the fixed plate 9. That is, the rotating plate 11 will not contact the pallet 21 when it moves downward, and there are no goods on the load rack 8 during the downward movement, so the risk of falling is small.

[0061] In actual use, a speed sensor can be installed on the rack 8, and a controller can be set to connect between the electric push rod 33 and the speed sensor.

[0062] If the pull rope 30 breaks or something similar happens when the rack 8 moves downwards, the rack 8 will fall. After the speed sensor detects that the speed exceeds the set threshold, it will transmit this information to the controller. The controller will control the telescopic end of the electric push rod 33 to retract quickly, so that the pallet 21 and the fixed plate 9 are in the same longitudinal plane. That is, when the rotating plate 11 moves downwards, it can contact one of the pallets 21 below it, thus achieving the same braking effect. The controller and its control principle are common technologies, which will not be described in detail here.

[0063] When the rack 8 moves downward, the pallet 21 is misaligned with the fixed plate 9, which does not affect the downward movement of the fixed plate 9, and an emergency braking is performed using a speed sensor in conjunction with an electric push rod 33.

[0064] In this automated warehouse, lifting devices 2 are mainly used to lift goods and place them on small or large shelves 3 or 4. When retrieving goods, operators use ladders or similar equipment to retrieve them piecemeal. This means that lifting devices 2 are used frequently for replenishment, carrying heavy loads and posing a significant risk of falls. In contrast, the shelves 8 are mostly unloaded and move downwards, relying solely on their own weight, thus posing a lower risk of falls. Therefore, during the replenishment process, it is crucial to be prepared for emergencies and respond quickly. During downward movement, without affecting the downward movement of the shelves 8, emergency measures can be taken using electric push rods 33 and speed sensors.

[0065] To ensure the connection strength between the rotating plate 11 and the fixed plate 9 during braking, a sliding channel 14 is provided on the rotating plate 11. A U-shaped frame 15 is slidably arranged inside the sliding channel 14. The open end of the U-shaped frame 15 is close to the fixed plate 9. One end of the U-shaped frame 15 inside the sliding channel 14 is inclined, and the top end is inclined away from the fixed plate 9.

[0066] Limiting rods 16 are fixedly connected to both the upper and lower ends of the U-shaped frame 15, and the limiting rods 16 are attached to the rotating plate 11. The limiting rods 16 are provided to ensure the stability of the sliding of the U-shaped frame 15, and the limiting rods 16 are made of high-strength materials, such as stainless steel, to ensure strength. At the same time, ball bearings or similar components can be provided at the contact position between the limiting rods 16 and the rotating plate 11 to ensure smooth sliding.

[0067] The top of the support plate 21 is provided with a top groove 22, and a top rod 23 is fixedly connected to the bottom of the top groove 22. The top of the top rod 23 extends out of the top groove 22, and the top of the top rod 23 abuts against the inclined surface of the U-shaped frame 15. The top of the top rod 23 can be provided with balls or the like to reduce the friction with the inclined surface of the U-shaped frame 15 and ensure the stable sliding of the U-shaped frame 15.

[0068] A second spring 27 is provided inside the sliding channel 14. One end of the second spring 27 is fixedly connected to the inner wall of the sliding channel 14, and the other end of the second spring 27 is fixedly connected to the U-shaped frame 15. The second spring 27 is provided for the reset of the U-shaped frame 15.

[0069] In its natural state (without being compressed, etc.), the U-shaped frame 15 is offset from the fixed plate 9 and will not come into contact with the fixed plate 9 (see reference). Figure 11 As shown in the image).

[0070] If the pull rope 30 breaks during the upward movement of the rack 8, the rack 8 and the goods will fall downward. The fixed plate 9 and the rotating plate 11 will move downward. The top of the top rod 23 will contact the inclined surface of the U-shaped frame 15. Since the U-shaped frame 15 is located at one end inside the sliding channel 14 and the top is tilted away from the fixed plate 9, the U-shaped frame 15 will move towards the fixed plate 9. Both the upper and lower ends of the U-shaped frame 15 will be engaged with the fixed plate 9. At this time, the U-shaped frame 15 will connect the rotating plate 11 and the fixed plate 9 into a whole, ensuring the support strength of the rotating plate 11 and the fixed plate 9.

[0071] If the top rod 23 loses contact with the U-shaped frame 15, the restoring force of the second spring 27 causes the U-shaped frame 15 to move away from the fixed plate 9 and return to its original position, without affecting the flipping of the rotating plate 11.

[0072] By setting up structures such as U-shaped frame 15 and top rod 23, and utilizing the movement of rotating plate 11, the rotating plate 11 and fixed plate 9 are connected into a whole, ensuring support strength and improving fall prevention efficiency, thereby ensuring the safety performance of the automated warehouse.

[0073] This invention achieves emergency braking by setting up structures such as a fixed plate 9, a rotating plate 11, a top rod 23, and a U-shaped frame 15, protecting goods, avoiding safety hazards, and not affecting the vertical movement of the rack 8. At the same time, the rotating plate 11 and the fixed plate 9 can be connected into a whole to improve the utilization efficiency of the automated warehouse.

[0074] The top rod 23 is fitted with a first spring 24. The bottom end of the first spring 24 is fixedly connected to the bottom of the top groove 22. The bottom end of the sliding channel 14 is fixedly connected to a pressure plate 25. The pressure plate 25 abuts against the first spring 24. The pressure plate 25 has a through groove 26 for the top rod 23 to be inserted. The first spring 24 is made of a strong material. When the first spring 24 is fully retracted, it can be retracted into the interior of the top groove 22.

[0075] Meanwhile, considering that during the flipping process, the end of the rotating plate 11 away from the fixed plate 9 will come into contact with the first spring 24, in actual use, a roller or other structure can be set at the end of the rotating plate 11 away from the fixed plate 9 to reduce wear between it and the first spring 24, ensure stable movement, and allow operators to perform regular maintenance and other operations, and adjust according to the specific usage.

[0076] By setting up structures such as the first spring 24, pressure plate 25, and through groove 26, in actual use, the fixed plate 9 and the rotating plate 11 move from top to bottom, and the top of the top rod 23 first passes through the through groove 26 and then contacts the inclined surface of the U-shaped frame 15. The top rod 23, pressure plate 25 and through groove 26 cooperate to connect the rotating plate 11 and the support plate 21 into a whole, ensuring the stability of the support.

[0077] At the same time, the pressure plate 25 compresses the first spring 24 to retract, and the first spring 24 retracts into the top groove 22. The first spring 24 relieves the force and buffers the impact of the fall.

[0078] Furthermore, the push rod 23 cooperates with the pressure plate 25 and the through groove 26 to guide the first spring 24, so that the first spring 24 can contract stably.

[0079] In addition, the pressure plate 25 limits the U-shaped frame 15 so that when the fixed plate 9 and the rotating plate 11 move from top to bottom, the top of the top rod 23 can stably contact the inclined surface of the U-shaped frame 15, instead of directly abutting the bottom of the U-shaped frame 15.

[0080] Considering that the U-shaped frame 15 mainly connects the rotating plate 11 and the fixed plate 9 into a whole from the outside, in order to further ensure the stability of the connection between the rotating plate 11 and the fixed plate 9, a crossbar 17 is fixedly connected to the inner wall of the U-shaped frame 15. A first hole section 18 is opened on the fixed shaft 10, a second hole section 19 is opened on the rotating plate 11, and a third hole section 20 is opened on the fixed plate 9. The first hole section 18, the second hole section 19, and the third hole section 20 are connected in sequence and allow the crossbar 17 to be inserted.

[0081] In its natural state (without being compressed, etc.), the U-shaped frame 15 is offset from the fixed plate 9 and will not come into contact with the fixed plate 9 (see reference). Figure 11 As shown in the diagram, the crossbar 17 will not extend into the interior of the first hole section 18, and will not affect the flipping of the rotating plate 11.

[0082] When the U-shaped frame 15 moves toward the fixed plate 9, and both ends of the U-shaped frame 15 are engaged with the fixed plate 9, the crossbar 17 is inserted into the first hole section 18, the second hole section 19, and the third hole section 20 in sequence, so that the rotating plate 11, the fixed shaft 10, and the fixed plate 9 are connected as a whole and are located within the rotating plate 11, the fixed shaft 10, and the fixed plate 9, cooperating with the U-shaped frame 15 and engaging in internal and external limiting.

[0083] By setting up structures such as crossbar 17, first hole section 18, second hole section 19 and third hole section 20, and by utilizing the movement of U-shaped frame 15, crossbar 17 is inserted into the first hole section 18, second hole section 19 and third hole section 20 in sequence, with internal and external limiting combined to further ensure support strength.

[0084] Furthermore, the crossbar 17, fixed shaft 10, etc. are all made of high-strength materials, such as stainless steel.

[0085] By setting up structures such as right-angle section 13, U-shaped frame 15, crossbar 17 and top bar 23, four-fold limiting is achieved to ensure the limiting effect and support stability.
