[0037] Embodiment 1

[0038] See also Figure 1-5The present invention is a shelf system for logistics picking operations. In a modern logistics warehousing environment, the system can greatly improve the picking efficiency and management convenience of goods. It mainly includes a shelf body 1. The shelf body 1 serves as the core supporting structure of the entire system and can carry various components and goods placed inside and on both sides thereof. A protective shell 2 is fixedly connected to one side of the shelf body 1. The protective shell 2 can fully protect its inner cavity structure from being damaged by external factors such as collision and dust, thereby ensuring the stable operation of the internal mechanism.

[0039] A height adjustment mechanism is provided in the inner cavity of the protective shell 2. This height adjustment mechanism can flexibly adjust the height of related equipment according to actual operation requirements, so as to adapt to workers of different heights and cargo storage requirements of different heights. An angle adjustment mechanism is provided on the front of the height adjustment mechanism. The angle adjustment mechanism can allow the related equipment to change the angle in the horizontal direction so as to more accurately scan cargo information or perform other operations. A storage and retrieval drive mechanism is fixedly connected to the other side of the shelf body 1. The storage and retrieval drive mechanism can provide power support for the storage and removal of goods, realize automated storage and retrieval operations, and improve work efficiency.

[0040] The height adjustment mechanism includes a first motor 3, and the surface of the first motor 3 is tightly fixedly connected to the protective shell 2 by bolts. Such a connection method can ensure the stability of the first motor 3 during operation, and is also convenient for disassembly when maintenance or replacement is required. The first motor 3 serves as the power source of the entire height adjustment mechanism and can provide power for the rotation of the gear 4. The output end of the first motor 3 is fixedly connected to the gear 4. When the first motor 3 starts to run, it can drive the gear 4 to rotate at high speed. The surface of the gear 4 is meshingly connected with a toothed plate 5, and the rotation of the gear 4 can drive the toothed plate 5 to move up and down. A fixed block 6 is fixedly connected to one side of the toothed plate 5, and the up and down movement of the toothed plate 5 can then drive the fixed block 6 to move up and down synchronously. Through such a series of transmission processes, the height of the scanner 14 can be accurately adjusted.

[0041] The angle adjustment mechanism includes a circular plate 7, the back of which is fixedly connected to a fixed block 6. When the fixed block 6 moves up and down under the action of the height adjustment mechanism, the circular plate 7 will move accordingly. The surface of the circular plate 7 is respectively fixedly connected with an arc-shaped worm gear 8 and a limiting guide rail 9. The inner cavity of the limiting guide rail 9 is slidably connected with a moving block 10. The moving block 10 can only move along a specific trajectory in the inner cavity of the limiting guide rail 9. Such a design can ensure the stability of the movement of the moving block 10. A connecting plate 11 is fixedly connected to one side of the moving block 10. The movement of the moving block 10 can drive the connecting plate 11 to move together. A second motor 12 is fixedly connected to the top of the connecting plate 11. The second motor 12 can provide power for the rotation of the worm 13. The output end of the second motor 12 passes through the inner cavity of the connecting plate 11 and is fixedly connected with a worm 13. When the second motor 12 starts working, it drives the worm 13 to rotate, and the worm 13 is meshed with the arc worm wheel 8, so the rotation of the worm 13 can drive the second motor 12 to make an arc motion on the arc worm wheel 8, the second motor 12 drives the connecting plate 11 to make an arc motion, and the connecting plate 11 drives the scanner 14 to make an arc motion, so as to realize the flexible adjustment of the angle of the scanner 14. In this process, the limit guide rail 9 cooperates with the moving block 10 to improve the stability of the connecting plate 11 and the scanner 14 when making an arc motion, and avoid shaking or offset. The scanner 14 fixedly connected to the surface of the connecting plate 11 has the main function of scanning cargo information. By quickly and accurately reading the barcode or other identification information on the cargo, it is convenient for the staff to identify, classify and manage the cargo.

[0042] The storage and retrieval drive mechanism includes a support block 15, and the support block 15 is fixedly connected to the electric telescopic rod 16 by bolts.

The electric telescopic rod 16 cooperates with the connecting block 17 to push the placement plate 18 and the partition 27 out of the shelf body 1, which is convenient for the staff to place or take out the goods, greatly improving the convenience of goods storage and retrieval.

[0043] Specifically: The shelf body 1 is used to support the inner wall and all structures on both sides. Its solid material and reasonable structural design can withstand greater weight and pressure to ensure the stability of the entire shelf system. The protective shell 2 can protect its inner cavity structure from being damaged. Whether in daily use or in a complex storage environment, the protective shell 2 can effectively protect the internal height adjustment mechanism and other components. The first motor 3 is fixedly connected to the protective shell 2 by bolts. This connection method is simple and reliable, which can not only ensure the stable installation of the first motor 3, but also facilitate disassembly and maintenance when the equipment fails. The first motor 3 provides power for the rotation of the gear 4. Its strong power output can ensure that the gear 4 rotates smoothly and quickly, thereby achieving efficient height adjustment. The gear 4 cooperates with the tooth plate 5, the fixing block 6, etc. to adjust the height of the scanner 14. The precise meshing and connection relationship between them can ensure the accuracy and stability of the scanner 14 during the height adjustment process. The second motor 12 provides power for the worm 13. The stable operation of the second motor 12 can ensure that the worm 13 rotates at a predetermined speed and direction. The worm 13 cooperates with the arc worm wheel 8 and other structures to adjust the angle of the scanner 14. Through this ingenious worm gear transmission structure, the precise control of the angle of the scanner 14 can be achieved. The moving block 10 can only move in the inner cavity of the limiting guide rail 9. The special design of the limiting guide rail 9 can limit the motion range of the moving block 10 so that it can only move along a specific track. The limiting guide rail 9 cooperates with the moving block 10 to improve the stability of the connecting plate 11 and the scanner 14 when they make arc motion. When the scanner 14 adjusts the angle to make an arc motion, the limiting guide rail 9 and the moving block 10 can effectively prevent it from shaking or shifting, ensuring the smooth progress of the scanning work. The scanner 14 is used to scan cargo information. It can quickly and accurately read various information on the cargo and provide important data support for logistics management. The support block 15 is fixedly connected to the electric telescopic rod 16 by bolts. The support block 15 can provide a stable support foundation for the electric telescopic rod 16 to ensure that it will not shake or shift during operation. The support block 15 can support and connect the electric telescopic rod 16. Its existence enables the electric telescopic rod 16 to be firmly installed on the shelf body 1. The connecting block 17 is used to connect the electric telescopic rod 16 with the placement plate 18. The connecting block 17 is reasonably designed and firmly connected, and can effectively transmit the telescopic power of the electric telescopic rod 16. The electric telescopic rod 16 cooperates with the connecting block 17 to push out the placement plate 18 and the partition 27, which is convenient for placing goods. In the process of storing and taking out goods, the coordinated work of the electric telescopic rod 16 and the connecting block 17 can greatly improve work efficiency.

The control box 32 protects the internal structure from being damaged. It can provide a safe working environment for the internal electronic components to prevent interference and damage from the outside.The fixing sleeve 33 is used to fix the electric telescopic rod 16 to maintain its stability during operation. When the electric telescopic rod 16 is working, the fixing sleeve 33 can effectively prevent it from shaking or displacement, thereby ensuring its normal operation.

[0051] The working principle of the present invention is as follows: the staff adjusts the position of the scanner 14 through the control panel 31. Various operation buttons and display screens are provided on the control panel 31. The staff can perform corresponding operations on the control panel 31 according to their needs and actual conditions. The first motor 3 is started, and the first motor 3 drives the gear 4 to rotate. The powerful power output of the first motor 3 can ensure that the gear 4 rotates quickly and smoothly. The gear 4 drives the tooth plate 5 to move up and down. The precise meshing relationship between the gear 4 and the tooth plate 5 can ensure that the tooth plate 5 moves up and down in a predetermined direction and speed. The tooth plate 5 drives the fixed block 6 to move up and down. The firm connection between the tooth plate 5 and the fixed block 6 can ensure that the fixed block 6 moves up and down synchronously with the tooth plate 5. The fixed block 6 drives the circular plate 7 and the scanner 14 to move up and down. Through this series of transmission processes, the scanner 14 can be adjusted to a suitable height to meet different scanning requirements. The second motor 12 is started, and the second motor 12 drives the worm 13 to rotate. The stable operation of the second motor 12 can ensure that the worm 13 rotates in a predetermined speed and direction. The worm 13 drives the second motor 12 to make an arc motion on the arc worm wheel 8. The ingenious transmission structure between the worm 13 and the arc worm wheel 8 can enable the second motor 12 to make a precise arc motion on the arc worm wheel 8. The second motor 12 drives the connecting plate 11 to make an arc motion. The fixed connection between the second motor 12 and the connecting plate 11 can ensure that the connecting plate 11 follows the second motor 12 to make an arc motion. The connecting plate 11 drives the scanner 14 to make an arc motion, so as to adjust the scanner 14 to a suitable angle. Through precise angle adjustment, it can be ensured that the scanner 14 can accurately scan the cargo information.

[0052] After the pickup voucher is scanned by the scanner 14, the scanner 14 will quickly and accurately read the information on the pickup voucher and transmit the information to the control system. The control system controls the extension of the electric telescopic rod 16 of the corresponding layer according to the received information. The electric telescopic rod 16 extends according to the predetermined length under the precise control of the control system. The electric telescopic rod 16 drives the connecting block 17 to move outward. The firm connection between the electric telescopic rod 16 and the connecting block 17 can ensure that the connecting block 17 moves outward with the electric telescopic rod 16. The connecting block 17 drives the placement plate 18 and the partition 27 to move outward. The connection between the connecting block 17 and the placement plate 18 can ensure that the placement plate 18 and the partition 27 are smoothly pushed out. The indicator light 28 on the corresponding placement plate 18 starts to flash. The indicator light 28 lights up under the control of the control system to indicate the specific location of the goods. The staff can quickly and accurately find the location of the goods according to the indication of the indicator light 28, and take out the goods on the placement plate 18, so as to achieve efficient and fast retrieval. After taking the goods, the electric telescopic rod 16 retracts to retract the placement plate 18 and the partition 27 into the shelf body 1. The electric telescopic rod 16 retracts under the control of the control system to safely retract the placement plate 18 and the partition 27 into the shelf body 1, ensuring the cleanliness of the shelf and the safe storage of goods.

[0053] When storing goods, the staff will take the goods to the scanner 14, scan the goods information and enter the storage location. The scanner 14 will read the information on the goods and transmit this information together with the storage location information entered by the staff to the control system. The control system will manage and store the goods according to this information. When the shelf needs to be moved, the electric push rod 21 is started, and the electric push rod 21 starts to work under the control of the control system. The electric push rod 21 contracts and drives the angle plate 22 to become a vertical state. The contraction movement of the electric push rod 21 is transmitted to the angle plate 22 through the rotating rod, so that the state of the angle plate 22 changes. The angle plate 22 drives the vertical plate 23 to be vertical, and the rotating rod connection between the angle plate 22 and the vertical plate 23 can ensure that the vertical plate 23 moves with the angle plate 22. The vertical plate 23 drives the inclined plate 24 to move to a vertical state, and the rotating rod connection between the vertical plate 23 and the inclined plate 24 can realize the state change of the inclined plate 24. The vertical plate 23 drives the universal wheel 20 to extend downward to contact the ground. At this time, the universal wheel 20 can bear the weight of the entire shelf system. Through its flexible steering and moving functions, it is convenient to move the shelf, whether it is shuttling through narrow passages in the warehouse or transferring between different work areas, it can be easily achieved. When the shelf does not need to be moved, the electric push rod 21 is started to extend. The extension movement of the electric push rod 21 is also transmitted to the corner plate 22 through the rotating rod, driving the retraction mechanism to a horizontal state. The retraction mechanism drives the universal wheel 20 to retract inward away from the ground. At this time, the shelf body 1 directly contacts the ground. With its stable structure and large contact area, the stability of the shelf is maintained to ensure that the goods will not be damaged due to the shaking of the shelf during storage.

[0054] In daily logistics picking operations, the entire shelf system greatly improves work efficiency and accuracy through the coordination of various mechanisms. The height adjustment mechanism and the angle adjustment mechanism can quickly and accurately adjust the position and angle of the scanner 14 according to different goods and the operating habits of the staff to ensure that the cargo information can be accurately read. The storage and retrieval drive mechanism realizes the automation of cargo storage and retrieval, reducing the tediousness and errors of manual operation. The design of the retracting mechanism and the universal wheel 20 allows the shelf system to flexibly switch between fixed use and mobile handling to adapt to different work scene requirements. The setting of the control panel 31 and the control box 32 allows the staff to easily operate and manage the entire system, while protecting the internal electronic components from external interference and damage.
