Technical Field

[0001] The invention belongs to the technical field of robots, and in particular relates to an electric-driven automatic sorting device for a stereoscopic warehouse. Background Art

[0002] With the rapid development of modern logistics and e-commerce industries, the requirements for warehousing and distribution efficiency are constantly increasing. Traditional manual sorting methods can no longer meet the needs of high efficiency and high precision, especially in large warehouses. Manual sorting is not only time-consuming but also prone to errors. Therefore, the application of automated sorting systems has become the key to solving this problem. At present, there are many automatic sorting devices on the market, such as conveyor belts, automated stackers, etc., but most of these devices are limited to two-dimensional plane operations and cannot fully utilize the three-dimensional space of the warehouse, resulting in low space utilization.

[0003] In order to further improve the utilization efficiency of storage space and enhance the automation and intelligence level of sorting system, the automatic sorting technology of stereoscopic warehouse came into being. The stereoscopic warehouse is a storage method that integrates vertical space storage, which can achieve higher storage density on limited ground area. Compared with the traditional flat storage system, the stereoscopic warehouse can effectively save space, reduce manual intervention and improve work efficiency.

[0004] Since the height of the three-dimensional warehouse is relatively high, sorting personnel need to use tools such as ladders or forklifts to take and place items on the shelves, which is more troublesome to operate. Therefore, an electric-driven automatic sorting device can be designed, which is suitable for moving and storing goods between the shelves in the three-dimensional warehouse.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figure 1 - Figure 6 As shown, an electric-driven stereoscopic warehouse automatic sorting device comprises:

[0031] An electric drive chassis 1, wherein a stand 2 is fixedly connected to the upper surface of the electric drive chassis 1, and a mounting frame 7 that can move up and down is slidably connected to the stand 2. The electric drive chassis can use the chassis of a mature smart car currently on the market, and can automatically control the movement and obstacle avoidance of the dispensing device;

[0032] A guide rail 10, wherein the guide rail 10 is slidably connected to the mounting frame 7, and a clamping plate 14 for pushing items on the stereoscopic warehouse is slidably connected to the end of the guide rail 10 along the length direction;

[0033] A conveying assembly, the conveying assembly is fixedly mounted on the mounting frame 7 and is used to convey the articles transferred by the clamping plate 14;

[0034] A shelf is arranged on the electric drive chassis 1 for stacking items delivered by the conveying assembly.

[0035] As can be seen from the above, by arranging the stand 2 and the mounting frame 7 on the electric drive chassis 1, and arranging the guide rail 10, the clamp 14 and the conveying assembly on the mounting frame 7, when taking items on the shelves of the stereoscopic warehouse, the electric drive chassis 1 can be used to drive the sorting device to move to the front of the corresponding shelf, slide the clamp 14 and the guide rail 10 so that the clamp 14 fits the side of the goods, slide the clamp 14 again to push the goods onto the guide rail 10, and the conveying assembly contacts the goods on the guide rail 10 to convey the goods to the shelf, and repeat this operation until the shelf is full. The device can automatically pick up and place items at different heights on the shelves of the stereoscopic warehouse without manual intervention, and can effectively speed up the picking and placing of goods, reduce manual intervention, and improve work efficiency.

[0036] A first motor 3 is fixedly connected to the electric drive chassis 1, and a lead screw 5 is rotatably connected to the inner wall of the stand 2. The end of the first output shaft 4 of the first motor 3 and the lead screw 5 are fixedly connected with first transmission gears 6 that mesh with each other. The lead screw 5 is threadedly connected to the mounting frame 7. When the first output shaft 4 of the first motor 3 rotates, the lead screw 5 can be driven to rotate through the first transmission gear 6, and the rotating lead screw 5 can then drive the mounting frame 7 to move up and down inside the stand 2.

[0037] A first electric telescopic rod 8 is fixedly connected to the mounting frame 7, and a mounting block 9 is fixedly connected to the end of the first electric telescopic rod 8. The mounting block 9 is slidably connected to the mounting frame 7, and the mounting block 9 is fixedly connected to the guide rail 10. When the first electric telescopic rod 8 is extended or retracted, it can drive the mounting block 9 to slide, and the mounting block 9 further drives the guide rail 10 to slide on the mounting frame 7, and the sliding guide rail 10 can drive the splint 14 to fit the surface of the cargo.

[0038] The side wall of the guide rail 10 is fixedly connected with a block 13, and is slidably connected to the clamping plate 14 through the block 13. The side wall of the guide rail 10 is fixedly connected with a second electric telescopic rod 15, and the telescopic end of the second electric telescopic rod 15 is fixedly connected to the clamping plate 14. When the clamping plate 14 is attached to the surface of the cargo, the second electric telescopic rod 15 contracts to drive the clamping plate 14 to slide on the block 13, and the clamping plate 14 can pull the clamped cargo onto the guide rail 10.

[0039] The conveying assembly includes a mounting frame 16 fixedly mounted on the mounting frame 7, a rotating shaft 17 rotatably connected to the inside of the mounting frame 16, and a worm wheel 18 fixedly mounted on the rotating shaft 17; the inner wall of the mounting frame 16 is rotatably connected to a worm 21 meshing with the worm wheel 18; a driving roller 19 is fixedly connected to the rotating shaft 17; a conveyor belt 20 is movably connected to the outside of the driving roller 19; a second motor 24 is fixedly connected to the end of the mounting frame 16; and a second transmission gear 25 meshing with each other is fixedly connected between the end of the output shaft of the second motor 24 and the end of the worm 21.

[0040] The output shaft of the second motor 24 drives the worm 21 to rotate through the second transmission gear 25. The rotating worm 21 drives the worm wheel 18 to rotate. The worm wheel 18 drives the driving roller 19 to rotate through the rotating shaft 17. The driving roller 19 drives the conveyor belt 20 to rotate. The conveyor belt 20 then drives the objects on the guide rail 10 to move, thereby realizing the transfer of objects. The upper surface of the conveyor belt 20 should be slightly higher than the upper surface of the guide rail 10 to facilitate the contact between the objects and the conveyor belt 20.

[0041] A telescopic rod 11 is fixedly connected to the end of the mounting frame 16, and both ends of the telescopic rod 11 are respectively fixedly connected to the guide rail 10. A positioning sensor 12 is fixedly connected to the telescopic rod 11. The positioning sensor 12 can collect the position information of the three-dimensional warehouse and power the intelligent system inside the chassis to determine the position of the items. The telescopic rod 11 can provide an end support for the guide rail 10 to prevent the end of the guide rail 10 from being deformed by force.

[0042] The vertical section of the guide rail 10 is L-shaped, which is convenient for objects to slide on the guide rail 10. The horizontal section of the clamping plate 14 is L-shaped, which is convenient for the end of the clamping plate 14 to be clamped on the surface of the object to drive the object to move.
