Description

Technical Field

[0001] This invention relates to the field of logistics technology, specifically to an unmanned automated sorting and transportation system for automated warehouses. Background Technology

[0002] Logistics is the physical flow of goods from the supply location to the receiving location. Through basic functions such as transportation, storage, loading and unloading, handling, packaging, distribution processing, delivery, and information processing, it realizes the spatial and temporal transfer of goods and occupies a key position in economic activities. The automated sorting and transportation system for automated warehouses refers to an integrated system that uses intelligent forklifts, AGVs, shuttles, stacker cranes, and other automated transportation equipment as handling carriers and intelligent control systems to automatically sort, handle, and transport goods in an automated warehouse environment. This system does not require direct human intervention and can automatically complete the identification, classification, handling, and transportation of goods according to order information or instructions from the warehouse management system. It is an important component of intelligent logistics systems.

[0003] However, when using intelligent forklifts in existing automated sorting and transportation systems for logistics warehouses, the forklifts may malfunction during operation, causing them to become stuck on the transport track. This could block the movement of subsequent intelligent forklifts, AGVs, or shuttles, forcing them to take detours and affecting sorting efficiency. Furthermore, when an intelligent forklift stops, the goods transported by it may remain on the equipment for an extended period. If the goods are temperature-sensitive and perishable, such as fresh produce or pharmaceuticals, exceeding a certain timeframe can lead to damage. If the goods are large, manually unloading them poses a high risk. Therefore, these systems do not meet current requirements. To address this, we propose an automated sorting and transportation system for logistics warehouses. Summary of the Invention

[0004] The purpose of this invention is to provide an unmanned automated sorting and transportation system for automated warehouses, addressing the problems mentioned in the background art. These problems include: when using existing automated forklifts in automated warehouses for cargo handling, the forklifts may malfunction and become stuck on the transport track, potentially blocking the movement of subsequent forklifts, AGVs, or shuttles, forcing them to take detours and affecting sorting efficiency; and when the forklift stops, the goods transported by it may remain on the equipment for an extended period, which can lead to damage if the goods are temperature-sensitive or perishable, such as fresh produce or pharmaceuticals, after a certain time. Furthermore, if the goods are large, manual unloading poses a significant risk.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an unmanned automatic sorting and transportation device for a logistics warehousing automated warehouse, comprising a self-replacing fault sorting and transportation mechanism, wherein the self-replacing fault sorting and transportation mechanism comprises a towing vehicle and two synchronous pushing mechanisms, wherein an intelligent forklift is provided in front of the towing vehicle and an intelligent replacement forklift is provided behind the towing vehicle, wherein an insert plate is fixed on the side of the intelligent forklift and the intelligent replacement forklift facing the towing vehicle, wherein both sides of the outer surface of the insert plate are first positioning inclined surfaces, and a slot is provided on one side of the outer surface of the first positioning inclined surface; The front and rear ends of the towing vehicle are each provided with a slot. Both sides of the inner wall of the slot are second positioning inclined surfaces. The inner wall of the second positioning inclined surface is provided with a strip groove. A fixing rod is slidably installed inside the strip groove. The position of the fixing rod corresponds to the position of the slot. The fixing rod located inside the two strip grooves on the same inner wall of the slot can be pushed towards the slot by a synchronous pushing mechanism.

[0006] Preferably, the synchronous pushing mechanism includes a stepper motor, the output shaft of which is connected to a threaded rod via a coupling, and a concave rod is mounted on the outer surface of the threaded rod via a threaded structure. Both sides of the outer surface of the concave rod are inclined surfaces, and the positions of the four inclined surfaces correspond to the positions of the four fixed rods respectively.

[0007] Preferably, a metal block is fixed to one side of the outer surface of the fixing rod, a metal rod is fixed to the side of the metal block facing the insert plate, and a spring connected to the metal block is sleeved on the outer surface of the metal rod.

[0008] Preferably, the upper surface of the towed transport vehicle is fixed with a cargo transfer mechanism, which includes two brackets. A lifting rod is fixed inside each of the two brackets. An intelligent lifting sleeve is movably installed on the outer surface of the lifting rod. A first lifting plate is fixed between the two intelligent lifting sleeves. A pressure sensor is fixed at each of the four corners of the upper surface of the first lifting plate. A second lifting plate is fixed on the upper surface of the four pressure sensors. A strip plate is fixed on both sides of the upper surface of the second lifting plate. A roller mounting bracket is provided on both sides inside the strip plate. Multiple electric rollers are fixed on the upper surface of the roller mounting bracket.

[0009] Preferably, each of the four corners of the lower end face of the roller mounting bracket is connected to an adaptive spring; On both sides below the roller mounting bracket, there is an angle fixing cylinder that is fixedly installed inside the second lifting plate. The face of the angle fixing cylinder facing the roller mounting bracket located on its upper end is connected to a fixing strip through a piston rod. A rubber strip is fixed to the upper end of the fixing strip.

[0010] Preferably, a lifting frame is provided on both sides above the second lifting plate, and the two lifting frames are respectively installed on the outer surface of the intelligent forklift and the intelligent replacement forklift; Multiple forklift levers are fixed to the lower side of the two opposing surfaces of the lifting frame. A cargo base is provided on the outer side of the multiple forklift levers near the intelligent forklift, and cargo is fixed to the upper surface of the cargo base. Both sides of the lower end face of the cargo base are provided with a T-shaped groove. The upper end face of the electric roller near the front end face of the second lifting plate is in contact with the upper inner wall of the T-shaped groove, and multiple forklift rods located at the front end of the second lifting plate are respectively located inside the two T-shaped grooves.

[0011] Preferably, one side of the slot is provided with a strip groove located on the outer surface of the towing vehicle, and multiple sensor cameras are fixedly installed inside the strip groove.

[0012] Preferably, a system for an unmanned automated sorting and transport device for a logistics warehousing automated warehouse as described in the claims comprises: a control system, a self-replacing faulty sorting and transport mechanism, a storage terminal, a transport cargo transfer mechanism, and a maintenance mechanism; The control system consists of a control computer. The overall system receives orders, inventory, and route instructions from the control computer, schedules tasks and assigns them in real time to the intelligent forklifts in the self-replacing fault sorting and transportation mechanism, which are the execution units. At the same time, the control system reads the signals of the intelligent forklifts in real time. Once an intelligent forklift malfunctions, it immediately locks the faulty intelligent forklift and dispatches a tow truck to drag it to the repair platform. The intelligent replacement forklift, which was originally located behind the intelligent forklift, continues to perform the unfinished sorting and transportation tasks along the original path of the intelligent forklift, ensuring that the flow of goods is not interrupted. At the same time, the control system updates the equipment status table and marks the faulty intelligent forklift as pending repair. After the faulty intelligent forklift is repaired and replaced with a working one, the system registers it as an intelligent replacement forklift for use.

[0013] Preferably, when the towing vehicle comes into contact with a malfunctioning intelligent forklift, the cargo transfer mechanism can transfer the cargo from the original intelligent forklift to the forklift lever on the intelligent replacement forklift. Then, the towing vehicle carries the empty intelligent forklift away from the main line. After receiving the cargo, the intelligent replacement forklift calibrates the cargo height and continues to perform sorting and transportation tasks along the original path. At the same time, the control system updates the inventory and task chain to ensure the flow of goods and warehouse location information.

[0014] Preferably, the storage terminal is composed of intelligent logistics warehouse racking, which is used to store goods at high density and provide three-dimensional coordinate storage locations for the control system; The maintenance facility consists of a maintenance platform, which includes a non-slip surface, diagnostic instruments, lifting equipment, and maintenance equipment. This maintenance facility helps technicians quickly locate and repair problems with the intelligent forklift.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When a smart forklift in use malfunctions and stops, the control computer monitoring the smart forklift will automatically dispatch a towing vehicle from the self-replacement sorting and transportation mechanism to pull the malfunctioning smart forklift to the repair platform for repair. The smart replacement forklift will then continue to perform the unfinished sorting and transportation tasks along the original path of the smart forklift, ensuring that the flow of goods is not interrupted. Through the above technical solution, a closed-loop management of "quickly taking off the line - repairing - reusing" faulty equipment can be realized, ensuring the 24 / 7 unmanned and efficient operation of the automated warehouse. 2. This invention, when a towing vehicle comes into contact with a malfunctioning intelligent forklift, uses a cargo transfer mechanism to transfer the goods from the original intelligent forklift to the forklift lever on the intelligent replacement forklift. The towing vehicle then carries the empty intelligent forklift away from the main line. After receiving the goods, the intelligent replacement forklift calibrates the cargo height and continues its sorting and transportation tasks along the original path. Simultaneously, the control system updates the inventory and task chain, confirming the flow of goods, timestamps, and storage location information. This technical solution quickly restores the flow of goods from malfunctioning intelligent forklifts, preventing fresh or pharmaceutical goods from being left on malfunctioning forklifts for extended periods, thus avoiding additional losses and injuries to workers when handling large items.

[0018] 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.

[0019] Please see Figures 1 to 8 An embodiment of the present invention provides an unmanned automated sorting and transportation device for a logistics warehouse, comprising a self-replacing fault sorting and transportation mechanism 27, which includes a towing vehicle 5 and two synchronous pushing mechanisms. An intelligent forklift 6 is provided in front of the towing vehicle 5, and an intelligent replacement forklift 7 is provided behind the towing vehicle 5. An insert plate 15 is fixed on the side of the intelligent forklift 6 and the intelligent replacement forklift 7 facing the towing vehicle 5. Both sides of the outer surface of the insert plate 15 are first positioning inclined surfaces 17, and a slot 16 is provided on one side of the outer surface of the first positioning inclined surface 17. The front and rear ends of the towing vehicle 5 are each provided with a slot 14. The inner walls of the slot 14 have two second positioning inclined surfaces 18 on both sides. The inner walls of the second positioning inclined surfaces 18 are provided with strip-shaped grooves 26. A fixing rod 13 is slidably installed inside the strip-shaped grooves 26. The position of the fixing rod 13 corresponds to the position of the slot 16. Through a synchronous pushing mechanism, the fixing rods 13 located inside the two strip-shaped grooves 26 on the same inner wall of the slot 14 can be pushed towards the slot 16. The unmanned automated sorting and transportation system for the automated warehouse consists of a control system, a self-replacing faulty sorting and transportation mechanism, and a storage system. The system consists of a terminal, a cargo transfer mechanism, and a maintenance mechanism; the storage terminal is composed of an intelligent logistics warehouse rack 1, which is used to store goods 25 in high density and provides a three-dimensional coordinate storage location for the control system; the control system is composed of a control computer 3, which receives orders, inventory and route instructions from the control computer 3, and schedules and dispatches tasks to the intelligent forklifts 6 in the self-replacing fault sorting and transportation mechanism as the execution unit. When the intelligent forklifts 6 receive instructions, they will pick up the goods 25 at the corresponding position and place them on the corresponding intelligent logistics warehouse rack 1.

[0020] A slot 14 has a strip-shaped groove on one side of the outer surface of the towed transport vehicle 5. Multiple sensor cameras 8 are fixedly installed inside the strip-shaped groove. During operation, the control computer 3 reads various signals from the intelligent forklift 6 in real time. If the intelligent forklift 6 malfunctions and stops or experiences other faults, the computer immediately locks onto the faulty forklift 6 and dispatches the towed transport vehicle 5. The dispatched towed transport vehicle 5 observes its surroundings through the sensor cameras 8, moves to the vicinity of the faulty intelligent forklift 6, and aligns its slot 14 with the insert plate 15 fixed to the outer surface of the faulty intelligent forklift 6. Once the slot 14 is aligned with the insert plate 15... The towing vehicle 5 will move towards the direction of the faulty intelligent forklift 6. As the towing vehicle 5 moves, the insert plate 15 will gradually enter the interior of the slot 14. During the process of the insert plate 15 entering the interior of the slot 14, the first positioning inclined surface 17 on the outer surface of the insert plate 15 will contact the two second positioning inclined surfaces 18 on both sides of the inner wall of the slot 14. Under the guidance of the first positioning inclined surface 17 and the second positioning inclined surface 18, when the insert plate 15 is fully inserted into the interior of the slot 14, the slot 16 on the first positioning inclined surface 17 on the outer surface of the insert plate 15 will be aligned with the fixing rod 13 inside the towing vehicle 5. With the first positioning inclined surface 17 and the second positioning inclined surface 18 in the above technical solution, even if there is some error between the position of the slot 14 and the insert plate 15, the insert plate 15 can still enter the interior of the slot 14, and as the insert plate 15 goes deeper, the position of the slot 14 and the insert plate 15 will be corrected.

[0021] The synchronous pushing mechanism includes a stepper motor 9. The output shaft of the stepper motor 9 is connected to a threaded rod 10 via a coupling. A concave rod 11 is mounted on the outer surface of the threaded rod 10 via a threaded structure. Both sides of the outer surface of the concave rod 11 are inclined surfaces 12, and the positions of the four inclined surfaces 12 correspond to the positions of the four fixed rods 13. A metal block 19 is fixed to one side of the outer surface of the fixed rod 13. A metal rod 21 is fixed to the side of the metal block 19 facing the insert plate 15. A spring 20 connected to the metal block 19 is sleeved on the outer surface of the metal rod 21. When the fixed rod 13 is aligned with the slot... After step 16, the stepper motor 9 is started to drive the threaded rod 10 connected to it to rotate. When the threaded rod 10 rotates, the concave rod 11 installed on the outer surface of the threaded rod 10 through the threaded structure will move inward or outward. When the concave rod 11 moves outward, the inclined surface 12 on the outer surface of the concave rod 11 will contact the fixing rod 13 and push the fixing rod 13 towards the slot 16. When the fixing rod 13 is inserted into the slot 16, the insert plate 15 and the intelligent forklift 6 fixed to the front end of the insert plate 15 can be fixed.

[0022] The maintenance mechanism consists of a maintenance platform 4, which includes a non-slip floor, diagnostic instruments, lifting equipment, and maintenance equipment. This maintenance mechanism helps technicians quickly locate and repair problems with the intelligent forklift 6. When the faulty intelligent forklift 6 is secured, it is towed to the maintenance platform 4 by a towing transport vehicle 5 for repair. Before being dispatched, the intelligent replacement forklift 7, located behind the towing vehicle 5, is fixed in place using the aforementioned fixing method. Before the towing vehicle 5 tows the faulty intelligent forklift 6 to the repair platform 4, the intelligent replacement forklift 7 continues to perform the unfinished sorting and transportation tasks along the original path of the intelligent forklift 6, ensuring that the cargo flow line is not interrupted. At the same time, the control system updates the equipment status table and marks the faulty intelligent forklift 6 as pending repair. After the faulty intelligent forklift 6 is repaired and personnel replace it with a normal one, the system assigns it to the intelligent replacement forklift 7 for use. The above technical solutions enable closed-loop management of faulty equipment, from "rapid removal from the line to repair and reuse," ensuring the efficient, unmanned operation of the automated warehouse 24 / 7. When the fixed rod 13 is pushed by the concave rod 11, the metal block 19 fixed to it will move along with it and compress the spring 20. When the malfunctioning intelligent forklift 6 is dragged onto the maintenance platform 4, the concave rod 11 is moved back to its original position by the stepper motor 9. As the concave rod 11 moves towards its original position, the reaction force of the compressed spring 20 can gradually push the fixed rod 13 outward, thereby releasing the fixation of the intelligent forklift 6. After the fixation of the intelligent forklift 6 by the towing vehicle 5 is released, the towing vehicle 5 moves to the standby area to wait for the next towing operation.

[0023] The upper surface of the towing vehicle 5 is fixed with a cargo transfer mechanism 2. The cargo transfer mechanism 2 includes two brackets 201. A lifting rod 202 is fixed inside each of the two brackets 201. An intelligent lifting sleeve 203 is movably installed on the outer surface of the lifting rod 202. A first lifting plate 204 is fixed between the two intelligent lifting sleeves 203. A pressure sensor 205 is fixed at each of the four corners of the upper surface of the first lifting plate 204. A second lifting plate 206 is fixed on the upper surface of the four pressure sensors 205. A strip plate 207 is fixed on both sides of the upper surface of the second lifting plate 206. A roller mounting bracket 208 is provided on both sides inside the strip plate 207. Multiple electric rollers 209 are fixed on the upper surface of the roller mounting bracket 208. A lifting frame 22 is provided on both sides above the second lifting plate 206. The two lifting frames 22 are respectively installed on the outer surfaces of the intelligent forklift 6 and the intelligent replacement forklift 7. Multiple forklift levers 23 are fixed to the lower side of the opposing surfaces of the two lifting frames 22. A cargo base 24 is provided on the outer side of the multiple forklift levers 23 near the intelligent forklift 6. A cargo 25 is fixed to the upper surface of the cargo base 24. After the intelligent forklift 6 is fixed to the towing vehicle 5, the first lifting plate 204 is moved upward by the intelligent lifting sleeve 203. When the first lifting plate 204 moves upward, the second lifting plate 206 connected to it by four pressure sensors 205 will also move upward. As the second lifting plate 206 rises as a whole, the rear end of the second lifting plate 206 will come into contact with the lower surface of the forklift lever 23 indirectly connected to the intelligent replacement forklift 7. When the two come into contact with each other, the pressure value detected by the two pressure sensors 205 near the rear end of the second lifting plate 206 suddenly increases. The intelligent replacement forklift 7 moves the connected forklift lever 23 upward together with the rise of the second lifting plate 206. As the second lifting plate 206 continues to rise, the front end of the second lifting plate 206 will contact the lower end surface of the cargo base 24 located outside the forklift arm 23 on the intelligent forklift 6. When the two are in contact, the pressure value detected by the two pressure sensors 205 near the front end of the second lifting plate 206 suddenly increases, and the second lifting plate 206 stops at the current position.

[0024] Both sides of the lower end face of the cargo base 24 are provided with a T-shaped groove. The upper end face of the electric roller 209 near the front end face of the second lifting plate 206 is in contact with the upper inner wall of the T-shaped groove. The multiple forklift rods 23 located at the front end of the second lifting plate 206 are respectively located inside the two T-shaped grooves. When the upper end face of the front end of the second lifting plate 206 is in contact with the lower end face of the cargo base 24, the distance between the second lifting plate 206 and the forklift rods 23 located inside the cargo base 24 is set as a quantitative data. When assembling the entire sorting and transportation system, the length of this quantitative data is measured and this positioning data is input into the control computer 3. When the second lifting plate 206 stops moving upward, the intelligent replacement forklift 7 moves this positioning data upward. After that, the forklift rods 23 on the intelligent replacement forklift 7 will be aligned with the forklift rods 23 on the intelligent forklift 6. When the second lifting plate 206 moves upward, the electric roller 209 inside the strip plate 207 on the upper surface of the second lifting plate 206 will move upward along with it. When the front end of the second lifting plate 206 contacts the cargo base 24, the upper surface of the electric roller 209 near the front end of the second lifting plate 206 will enter the interior of the T-shaped groove on the lower surface of the cargo base 24 and fit against the upper inner wall of the T-shaped groove. When the two fit against each other, the electric roller 209 is rotated to push the first lifting plate 204 as a whole and the pressure sensor 205 fixed on the upper surface of the first lifting plate 204 toward the intelligent replacement forklift 7 until the cargo base 24 is completely moved to the outside of the multiple forklift levers 23 connected to the intelligent replacement forklift 7. At the same time, the cargo 25 on the upper surface of the cargo base 24 will be transferred to the intelligent replacement forklift 7. After the goods 25 are transferred, the tow truck 5 carries the empty intelligent forklift 6 away from the main line. The intelligent replacement forklift 7 calibrates the height of the pallet after receiving the goods and continues to perform the sorting and transportation tasks along the original path. At the same time, the control system updates the inventory and task chain to ensure the flow and storage location information of the goods 25. The above technical solution enables the goods on the faulty intelligent forklift 6 to be quickly moved back to their original state, thereby preventing fresh or pharmaceutical goods 25 from being left on the faulty intelligent forklift 6 for a long time, which would result in additional losses and prevent workers from being injured when unloading large goods 25.

[0025] Each of the four corners of the lower end face of the roller mounting bracket 208 is connected to an adaptive spring 210; On both sides below the roller mounting bracket 208, there is an angle fixing cylinder 211 fixedly installed inside the second lifting plate 206. The face of the angle fixing cylinder 211 facing the roller mounting bracket 208 located on its upper end is connected to the fixing strip 212 through the piston rod. The upper end face of the fixing strip 212 is fixed with a rubber strip. In order to prevent the goods 25 being transported from falling, some existing intelligent forklifts 6 will tilt the forklift lever 23 after lifting the goods 25 by the forklift lever 23. When the forklift lever 23 tilts, the goods 25 above it will tilt along with it, so that the goods 25 will fall. When the cargo 25 is transferred while tilted, the multiple electric rollers 209 near the front end of the second lifting plate 206 contact the cargo base 24, causing the second lifting plate 206 to continue rising. As the second lifting plate 206 rises, the roller mounting brackets 208 fixed to the lower end of the multiple electric rollers 209 near the front end of the second lifting plate 206 will tilt as a whole, compressing the adaptive spring 210 located on its lower end. When the pressure value detected by the pressure sensor 205 near the front end of the second lifting plate 206 suddenly increases, the upward movement of the second lifting plate 206 stops. Then, the angle fixing cylinder 211 is activated to push the fixing bar 212 upward. As the fixing bar 212 rises, the rubber strip fixed to the upper end face of the fixing bar 212 will come into contact with the lower end face of the tilted roller mounting bracket 208, thereby supporting the roller mounting bracket 208 and the electric roller 209 fixed to the upper end face of the roller mounting bracket 208. When the angle fixing cylinder 211 can no longer push the fixing bar 212 upward, the first lifting plate 204 and the pressure sensor 205 are transferred to the forklift rod 23 on the outer surface of the intelligent replacement forklift 7 by the supported and fixed electric roller 209. The above technical solution can increase the number of electric rollers 209 that are in contact with the first lifting plate 204 in the tilted state, thereby preventing the situation where the number of electric rollers 209 connected to the first lifting plate 204 is too small and the pressure sensor 205 located on the upper surface of the first lifting plate 204 is too heavy, so that the cargo base 24 and cargo 25 cannot be moved by a small number of electric rollers 209 alone.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
