Description

Technical Field

[0001] This invention relates to the field of automated warehousing and logistics equipment, and in particular to a stacker crane for warehousing flame-retardant corrugated cardboard. Background Technology

[0002] Stacker cranes are automated material handling equipment used in automated warehouses or high-density storage environments. Their main function is to automatically stack and transport goods within narrow aisles. They can efficiently and accurately manage the storage location of goods according to preset operation sequences and paths, significantly improving warehouse space utilization and operational efficiency, while reducing the labor intensity and safety risks of manual handling. They are widely used in logistics, manufacturing, and the automated inbound and outbound operations of lightweight, bulky materials such as cardboard boxes and corrugated cardboard.

[0003] In modern warehousing and logistics, corrugated cardboard is widely used for packaging and transportation due to its lightweight, flammable, and easy-to-stack properties. However, it poses significant safety hazards during warehousing and storage in automated warehouses. Traditional aisle stacker cranes lack fire-resistant isolation designs for flammable materials when handling and stacking corrugated cardboard. Once the cardboard accidentally catches fire, existing equipment cannot isolate or control the fire source in time, and cannot prevent the flames and high temperatures from spreading to other areas of the warehouse, increasing the risk of fire. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that traditional aisle stacker cranes in the prior art lack fireproof isolation design for flammable materials when handling and stacking corrugated cardboard. Once the cardboard accidentally catches fire, the existing equipment is unable to isolate or control the fire source in time, and cannot prevent the flames and high temperatures from spreading to other areas of the warehouse, thus increasing the risk of fire. Therefore, a flame-retardant aisle stacker crane for corrugated cardboard warehousing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A flame-retardant corrugated cardboard warehousing stacker includes a butt plate and a horizontal U-frame. A support rod is fixedly connected to the top of the butt plate, and one end of the horizontal U-frame is rotatably connected to the support rod. A loading assembly is mounted on the top of the horizontal U-frame, carrying the corrugated cardboard. A composite lifting and traversing mechanism is provided on one side of the butt plate, driving the loading assembly to lift and move laterally along a vertical plane. An edge box is fixedly connected to one end of the butt plate, and an isolation box is fixedly connected to the end of the edge box away from the butt plate to buffer temporarily ignited corrugated cardboard. A closing plate is rotatably connected to the top of the isolation box, and a sequential linkage sealing mechanism is provided inside the edge box. First, the loading assembly is driven to flip from a horizontal to an inclined state, causing the corrugated cardboard to slide into the isolation box. After the corrugated cardboard has completely fallen into the isolation box, the flipping linkage sealing mechanism continues to drive the closing plate to fall and close the opening of the isolation box.

[0006] Optionally, the flip-link sealing mechanism includes a hot-melt trigger safety lock, a trigger plate, a support rod, a push rod, a middle block, an elastic column, and an anti-accidental contact component. The anti-accidental contact component prevents non-corrugated cardboard from falling into the isolation box and causing the sealing plate to close accidentally.

[0007] Optionally, the thermo-melt trigger safety lock is fixedly connected to the top of the support rod, the output end of the thermo-melt trigger safety lock extends into the bottom of the horizontal U-frame, a connecting rod is fixedly connected to the side of the trigger plate, a middle groove is opened in the inner cavity of the isolation box, an elastic column is fixedly connected to the bottom of the connecting rod, the bottom end of the elastic column is fixedly connected to the bottom of the middle groove, and a middle block is fixedly connected after the connecting rod extends out from the middle groove.

[0008] Optionally, the middle block is symmetrically rotatably connected to a slanted push rod on its side, and a vertical rod is rotatably connected to the end of the slanted push rod away from the middle block. A supporting slanted rod is rotatably connected to the top of the vertical rod, and a rectangular groove is opened at the bottom of the closed plate, into which the supporting slanted rod extends.

[0009] Optionally, the anti-accidental touch component includes a central rod, a driven magnet, a horizontal spring, a mounting plate, and an active magnet. The central rod is fixedly connected to the top of the central block, and a cylindrical cavity is formed at the top of the central rod.

[0010] Optionally, a mounting plate is screwed into one end of the intermediate rod in the cylindrical cavity, the mounting plate is fixedly connected to one end of the horizontal spring, the other end of the horizontal spring is fixedly connected to a driven magnet, and a guide slope is fixedly connected to the top of the edge box.

[0011] Optionally, the edge box has an insertion hole on its side, the driven magnet extends into the insertion hole, a receiving block is fixedly connected to the edge box below the insertion hole, and an active magnet is fixedly connected to the middle position of the side of the horizontal U-frame, the active magnet and the driven magnet have the same magnetism on their opposite sides.

[0012] Optionally, the loading assembly includes a feeding roller, a feeding motor, and a feeding belt. Feeding rollers are rotatably connected to both ends of the horizontal U-frame. The outer walls of the two feeding rollers are fitted with the same feeding belt. The shaft of one of the feeding rollers is fixedly connected to the output end of the feeding motor. The housing of the feeding motor is fixedly connected to the horizontal U-frame.

[0013] Optionally, the composite lifting and traversing mechanism includes a vertical lifting mechanism, a horizontal traveling mechanism, a bottom seat, an edge frame, and a traveling frame. The bottom seat is vertically fixed to both ends with edge frames, and I-beams are fixedly connected to the top of the two edge frames. A U-shaped block is fixedly connected to the top of the traveling frame, and traveling wheels are symmetrically rotatably connected to the sides of the U-blocks. The traveling wheels extend into the slots of the I-beams.

[0014] Optionally, the vertical lifting mechanism includes a synchronous pulley, a synchronous belt, and a lifting motor. The upper and lower ends of the side of the traveling frame are rotatably connected to synchronous pulleys. The two synchronous pulleys share the same synchronous belt. The shaft of the synchronous pulley at the bottom of the traveling frame is fixedly connected to the output end of the lifting motor. The lifting motor is fixedly connected to the traveling frame. A synchronous rod is fixedly connected to the outer wall of the synchronous belt. The synchronous rod is fixedly connected to the docking plate. The docking plate is slidably connected to a vertical guide rail in the vertical direction. The vertical guide rail is fixedly connected to the side of the traveling frame.

[0015] Optionally, the lateral walking mechanism includes a walking rack, a transfer motor, and a walking gear. The transfer motor is fixedly connected to the bottom end of the walking frame, and the walking gear is fixedly connected to the output end of the transfer motor. The walking gear is stably meshed with the walking rack. The walking rack is fixedly connected to the top of the bottom seat. The bottom seat is fixedly connected to a bottom horizontal rail on one side of the walking rack, and the bottom end of the walking frame is slidably connected to the outer wall of the bottom horizontal rail.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This invention, by installing an isolation box and sealing plate structure on one side of the stacker crane in the aisle, allows the corrugated cardboard to automatically seal itself after sliding into the isolation box when it catches fire due to friction or heat during handling or stacking. This effectively isolates the fire source physically, preventing the flames from spreading to the stacker crane and warehouse interior, significantly reducing the risk of fire spread. Simultaneously, the isolation box creates a partially enclosed environment, limiting oxygen supply and suppressing the combustion process, providing safe conditions for subsequent fire extinguishing or cooling, and significantly improving storage safety.

[0017] 2. This invention is equipped with a flip-linked sealing mechanism, which can automatically drive the sealing plate to fall after the corrugated cardboard slides into the isolation box, realizing continuous linkage between the box entry and sealing actions. It adopts a mechanical structure linkage method, which does not require an independent electrical control system. It can still operate reliably even under high temperature or abnormal conditions, and has high safety and stability. In the event of a fire, the system can automatically complete the entire process of "material dropping-isolation-sealing", reducing manual intervention and reaction time, thereby effectively ensuring the safety of operators and the storage environment.

[0018] 3. The anti-accidental touch component of this invention, through the magnetic repulsion between the active and driven magnets combined with the elastic reset structure, can effectively prevent the sealing action caused by accidental touch of non-corrugated cardboard. It remains stable under normal warehousing conditions. When high temperature or abnormal combustion occurs, the safety lock will be triggered by heat melting before the linkage closure will be initiated, thus ensuring selective triggering of the sealing mechanism. This achieves the combination of anti-accidental touch and automatic safety response, improves the intelligent protection level of the equipment, and ensures that the stacker crane can operate safely and reliably under various working conditions.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Reference Figures 1-13 A flame-retardant corrugated cardboard warehousing stacker includes a butt plate 9 and a transverse U-frame 13. A support rod 8 is fixedly welded to the top of the butt plate 9. One end of the transverse U-frame 13 is rotatably connected to the support rod 8 by a pin. A loading component is provided on the top of the transverse U-frame 13. The loading component carries the corrugated cardboard. The transverse U-frame 13 can rotate relative to the support rod 8 around the pin. When the loading component transfers the corrugated cardboard, it is supported by the output end of the heat-activated safety lock 81 and is in a horizontal state. When the heat-activated safety lock 81 is heated and its output end retracts, the end of the transverse U-frame 13 near the heat-activated safety lock 81 is not supported. The transverse U-frame 13 will then rotate and fall around the pin of the support rod 8, releasing the stacked corrugated cardboard on the top of the transverse U-frame 13.

[0036] The loading assembly includes two feeding rollers 110, a feeding motor 11, and a feeding belt 12, as shown in the reference. Figure 5The left and right ends of the horizontal U-frame 13 are rotatably connected to feeding rollers 110 by pins. The outer walls of the two feeding rollers 110 are fitted with the same feeding belt 12. To achieve the driving function, the shaft of one of the feeding rollers 110 is fixedly connected to the output end of the feeding motor 11 by a coupling. The housing of the feeding motor 11 is fixedly connected to the horizontal U-frame 13 by bolts. The power output by the feeding motor 11 directly acts on the feeding rollers 110, so that the feeding belt 12 forms a continuous cyclic conveying path between the two feeding rollers 110. Through the cyclic movement of the feeding belt 12, the stacked corrugated cardboard is fed into the stacking position of the aisle.

[0037] A composite lifting and traversing mechanism is provided on one side of the docking plate 9. The composite lifting and traversing mechanism drives the load assembly to lift and move laterally in the vertical plane. The composite lifting and traversing mechanism includes a vertical lifting mechanism, a traversing mechanism, a bottom seat 3, an edge frame 2, and a traveling frame 5. The bottom seat 3 is vertically fixed to the edge frame 2 at both ends with bolts. The bottom seat 3 is the basic support component of the composite lifting and traversing mechanism. Its overall shape is long and narrow to adapt to the walking direction of the stacker crane.

[0038] Two edge frames 2 are fixedly welded to the top of I-beams 1. The I-beams 1 have an I-shaped cross section and have slotted structures extending along the length direction at both the top and bottom. The I-beams 1 serve as the track components of the transverse traveling mechanism, providing reliable guidance and rolling channels for the traveling wheels, thereby enabling the traveling frame 5 to move smoothly along the length direction of the I-beams 1. A U-shaped block 4 is fixedly welded to the top of the traveling frame 5. Traveling wheels 41 are symmetrically rotatably connected to the sides of the U-shaped block 4. There are four traveling wheels 41 in total. The traveling wheels 41 extend into the slots of the I-beams 1. By embedding the traveling wheels 41 into the slots of the I-beams 1, a stable guiding constraint relationship is formed, allowing the traveling frame 5 to move in a straight and smooth transverse direction along the length direction of the I-beams 1, while preventing derailment or swaying caused by lateral forces.

[0039] The vertical lifting mechanism includes synchronous pulleys 71, a synchronous belt 710, and a lifting motor 7. Synchronous pulleys 71 are rotatably connected to both the upper and lower ends of the side of the traveling frame 5. The two synchronous pulleys 71 share the same synchronous belt 710, forming a closed loop transmission path along the side of the traveling frame 5. The shaft of the synchronous pulley 71 at the bottom of the traveling frame 5 is fixedly connected to the output end of the lifting motor 7 using a coupling. The housing of the lifting motor 7 is bolted to the traveling frame 5. A synchronous rod 10 is bolted to the outer wall of the synchronous belt 710. The timing rod 10 is fixedly welded to the docking plate 9. When the lifting motor 7 drives the synchronous belt 710 to circulate around the synchronous pulley 71, the timing rod 10 will drive the docking plate 9 to rise and fall in the vertical direction, realizing the vertical displacement of the entire load assembly. Finally, in order to ensure the stability of the lifting motion and prevent the docking plate 9 from shaking or swaying during the lifting process, the docking plate 9 is slidably connected to the vertical guide rail 72. The vertical guide rail 72 is fixedly connected to the side of the traveling frame 5 with bolts. During the lifting process, the docking plate 9 is controlled by the guiding constraint of the vertical guide rail 72, thereby maintaining the stability of the lifting posture.

[0040] The lateral travel mechanism includes a travel rack 31, a transfer motor 6, and a travel gear 61. The transfer motor 6 is bolted to the bottom of the travel frame 5. The output end of the transfer motor 6 is fixedly connected to the central shaft of the travel gear 61 via a key or coupling. To provide immediate protection at the meshing point between the travel gear 61 and the travel rack 31, a protective cover 51 is bolted to the top of the transfer motor 6 on the travel frame 5, allowing the power of the transfer motor 6 to directly act on the travel gear 61. The transfer motor 6 drives the travel gear 61 to rotate, thereby achieving meshing drive of the travel rack 31. The travel rack 31 is arranged linearly along the tunnel direction and fixedly connected to the top of the bottom seat 3. The travel rack 31 is a straight rack with teeth, and its tooth surface matches the tooth profile of the travel gear 61, forming a reliable and stable meshing relationship between the two.

[0041] Through the transmission method of gear-rack structure, the transfer motor 6 can convert the rotation speed into the linear displacement of the walking frame 5, realizing precise lateral movement control. In order to further limit the movement trajectory of the walking frame 5 and improve its stability during lateral movement, the bottom seat 3 is bolted to the side of the walking rack 31 with a bottom horizontal rail 32. The bottom end of the walking frame 5 is slidably connected to the outer wall of the bottom horizontal rail 32. Through the guiding effect of the bottom horizontal rail 32, the walking frame 5 can be effectively prevented from shaking or deviating due to lateral force, so that the operation of the lateral walking mechanism is smoother.

[0042] An edge box 14 is fixedly welded to one end of the connecting plate 9, and an isolation box 15 is fixedly welded to the end of the edge box 14 away from the connecting plate 9 to buffer the temporarily burning corrugated cardboard. The top of the edge box 14 has an isolation box 15 with a hinged rotating connection to a closing plate 16. When the closing plate 16 covers the top opening of the isolation box 15, the closing plate 16 and the isolation box 15 form a sealed temporary corrugated cardboard buffer container to prevent the fire from spreading.

[0043] The edge box 14 is equipped with a sequential linkage sealing mechanism. First, it drives the load assembly to flip from a horizontal state to an inclined state, so that the corrugated cardboard slides into the isolation box 15. After the corrugated cardboard has completely fallen into the isolation box 15, the flip linkage sealing mechanism continues to drive the closing plate 16 to fall and close the opening of the isolation box 15. All components of the flip linkage sealing mechanism are located inside the edge box 14. The flip linkage sealing mechanism includes a hot melt trigger safety lock 81, a trigger plate 17, a support diagonal bar 20, a diagonal push rod 22, a middle block 23, and an elastic column 19.

[0044] The thermo-touch trigger safety lock 81 is bolted to the top of the support rod 8. The output end of the thermo-touch trigger safety lock 81 extends into the bottom of the horizontal U-frame 13. The thermo-touch trigger safety lock 81 is an existing standard part. It has a thermo-touch trigger inside. When the external temperature reaches the set melting temperature of the safety lock, the thermo-touch trigger softens or melts due to heat, causing the locking mechanism inside the safety lock to release automatically. After the thermo-touch trigger melts, the output end of the thermo-touch trigger safety lock 81 will automatically retract under the action of the internal elastic reset structure. At this time, the horizontal U-frame 13 will automatically tilt, quickly releasing the corrugated cardboard into the isolation box 15.

[0045] The trigger plate 17 extends into the inner cavity of the isolation box 15 and matches the cross-sectional dimensions of the inner cavity of the isolation box 15. A connecting rod 18 is fixedly welded to the side of the trigger plate 17. A central groove 153 is opened in the inner cavity of the isolation box 15. An elastic column 19 is fixedly connected to the bottom of the connecting rod 18. The bottom end of the elastic column 19 is fixedly connected to the bottom of the central groove 153. When the elastic column 19 is in a circular shape, it will support the trigger plate 17 at a certain height in the inner cavity of the isolation box 15. After the connecting rod 18 extends out from the central groove 153, a central block 23 is bolted to it. A symmetrically rotating inclined push rod 22 is connected to the side of the central block 23 by a pin. A vertical rod 21 is rotatably connected to the end of the inclined push rod 22 away from the central block 23. A supporting inclined rod 20 is rotatably connected to the top of the vertical rod 21. A rectangular groove 161 is opened at the bottom of the sealing plate 16. The supporting inclined rod 20 extends into the rectangular groove 161. Figure 5 At this time, the sealing plate 16 is obliquely supported above the isolation box 15. When the trigger plate 17 is forced to move down, it will force the two supporting oblique rods 20 to move away from each other through the middle block 23, the oblique push rod 22, and the vertical rod 21. The supporting oblique rods 20 will disengage from the rectangular groove 161. At this time, the sealing plate 16 will automatically fall down due to its own weight to close the top opening of the isolation box 15.

[0046] Obviously, as long as the trigger plate 17 is subjected to downward pressure, the corresponding mechanism will cause the closing plate 16 to close the opening of the isolation box 15. However, it is impossible to determine whether the object falling into the isolation box 15 is burning corrugated cardboard. Therefore, it is necessary to set up an anti-accidental contact component. The anti-accidental contact component prevents non-corrugated cardboard from falling into the isolation box 15 and causing the closing plate 16 to close accidentally. The anti-accidental contact component includes a middle rod 24, a driven magnet 25, a horizontal spring 26, a mounting plate 27, and an active magnet 131. The middle rod 24 is fixedly welded to the top of the middle block 23, and the top of the middle rod 24 has an opening. A cylindrical cavity has a central rod 24 screwed into one end of a mounting plate 27. The mounting plate 27 is fixedly welded to one end of a horizontal spring 26, and a driven magnet 25 is fixedly welded to the other end of the horizontal spring 26. A guide slope 141 is fixedly welded to the top of the edge box 14. An insertion hole 142 is opened on the side of the edge box 14, and the driven magnet 25 extends into the insertion hole 142. A receiving block 143 is fixedly connected to the edge box 14 below the insertion hole 142. An active magnet 131 is fixedly connected to the middle position of the side of the horizontal U-frame 13. The active magnet 131 and the driven magnet 25 have the same magnetism on opposite sides.

[0047] The specific implementation steps and principles of this invention are as follows: refer to Figure 5 When the entire assembly is working normally, the elastic column 19 is at its original length, the trigger plate 17 is at a high position, the two support diagonal rods 20 are inside the rectangular groove 161, the sealing plate 16 is diagonally supported on the top of the isolation box 15, the thermo-trigger safety lock 81 is in normal working condition, the output end of the thermo-trigger safety lock 81 remains extended, the horizontal U-frame 13 is supported in a horizontal state, the driven magnet 25 is inside the insertion hole 142, at this time the middle block 23 cannot move in the vertical direction, even if debris falls into the isolation box 15, the trigger plate 17 will not move down.

[0048] At a low position, the worker places multiple corrugated cardboard pieces onto the top of the feeding belt 12, and then starts the transfer motor 6 and the lifting motor 7 in sequence. The rotating motor 6 drives the traveling frame 5 to move laterally along the bottom seat 3 through the traveling gear 61 and the traveling rack 31. On the other hand, the lifting motor 7 drives the synchronous pulley 71 to rotate, and uses the synchronous belt 710 to move all the structures on the docking plate 9 to the required position. Finally, the feeding motor 11 is started, and the feeding belt 12 is driven by the feeding roller 110 to send the corrugated cardboard into the aisle stacking position.

[0049] When the corrugated cardboard on top of the feeding belt 12 accidentally burns during transfer, the heat-triggered safety lock 81 is unlocked by heat, the output end of the heat-triggered safety lock 81 retracts, one end of the horizontal U-frame 13 is not supported, the horizontal U-frame 13 tilts to one side of the edge box 14, and finally the bottom overlaps the top of the receiving block 143. Here, the active magnet 131 repels the driven magnet 25, and the driven magnet 25 retracts from the insertion hole 142 back into the edge box 14, and the middle block 23 can move freely in the vertical direction.

[0050] During this process, the corrugated cardboard on the horizontal U-frame 13 slides rapidly into the isolation box 15 due to the tilt of the horizontal U-frame 13, which will press the trigger plate 17 to move down. The trigger plate 17 drives the middle block 23 to move down through the connecting rod 18, and forces the two vertical rods 21 to move away from each other through the inclined push rod 22. The tops of the two supporting inclined rods 20 are separated from the rectangular groove 161, and the two supporting inclined rods 20 hang down naturally and are in a horizontal state. At this time, the sealing plate 16 is not supported, and naturally closes the top opening of the isolation box 15. The burning corrugated cardboard inside the isolation box 15 gradually extinguishes itself due to lack of oxygen.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
