Description

TECHNICAL FIELD

[0001] The present application relates to the field of warehouse management, in particular to an intelligent shelf system based on Internet of Things technology. BACKGROUND

[0002] Traditional warehouse management systems rely on manual operation, which has many drawbacks, such as low space utilization, frequent manual intervention, and non-transparent data management. These problems lead to low operational efficiency and frequent errors. Specifically, traditional shelves do not make full use of vertical space, and the storage density is low. The storage and retrieval of goods mainly relies on manual operation, which not only has low efficiency, but also is prone to loss due to human error. In addition, the lack of real-time data collection and analysis means makes the inventory status update lag, and managers are difficult to obtain accurate inventory information, thereby affecting the effectiveness of inventory management strategies.

[0003] Although there are some automated shelf systems on the market that attempt to solve these problems, these systems have limited automation, insufficient data analysis capabilities, and lack real-time monitoring functions, and still cannot fully meet the needs of modern warehouse management.

[0004] A three-dimensional intelligent shelf device is disclosed in Chinese Patent No. 202211470293.0, which includes a plurality of parallel roller conveyors, and the roller conveyors include an inner frame and an outer frame. The cooperation of the roller conveyors, the connecting seats one, two and three, and the fixing seat can replace the traditional fixed shelves with a three-dimensional flow type shelf, which can move the goods on the same shelf during loading or unloading, clearly see the storage and condition of each good, and facilitate the management of staff, while increasing the flexibility of loading or unloading.

[0005] A logistics warehouse intelligent shelf is disclosed in Chinese Patent No. 202410534820.2, which includes a shelf body, a goods pusher, a pusher layer changing mechanism, a goods lifting platform and a control module. The pusher layer changing mechanism moves the track docking seat to the specified storage plate layer according to the instructions of the control module, and is flush with the track. The goods pusher includes a body, a folding arm and a walking wheel, and an optical alignment module is arranged between the two goods pushers. The goods lifting platform is located at the end of the shelf body. A plurality of addressing points are arranged at equal intervals on the track, and an addressing device is arranged on the goods pusher. The present application has relatively low cost and flexible use, and can realize intelligent picking and placing of scattered order goods.

[0006] However, there are still the following problems in practical application:

[0007] 1. Limited automation: Although both patents achieve some degree of automation, there is still a lot of manual intervention in the access of goods, and full automatic precise control is not achieved.

[0008] 2. Insufficient data analysis capability: Most existing automated shelf systems fail to fully utilize big data analysis technology to generate detailed inventory reports and prediction models to optimize inventory management strategies.

[0009] 3. Lack of real-time monitoring function: Both patents do not provide comprehensive real-time monitoring function, which cannot dynamically track the position and state of the tray, increasing the risk of misoperation.

[0010] 4. Weak remote monitoring and management capability: Although the existing system has certain Internet of Things connection function, the support for remote monitoring and management is limited, which is difficult to meet the complex warehousing needs.

Then the first bidirectional motor 414 is controlled to reverse, and the pushing frame 412 is returned. In the process of moving the tray 3 on the pushing groove 411, the limiting groove 425 moves above the conveying plate 424. When the corresponding first magnet 417 and second magnet 418 abut against each other, the conveying plate 424 is controlled to move until the second position sensor 429 detects that the tray 3 abuts against the first stop bar 416.

[0077] After the tray 3 abuts against the first stop bar 416, at this time, the second magnet 418 and the third magnet 435 abut against each other. The third bidirectional motor 433 is controlled by the control panel 7 to work, and the third screw rod 432 is driven to rotate, so that the moving plate 434 pushes the tray 3 to move along the moving groove 431. When moving to the end, the second electric push rod 437 is controlled by the control panel 7 to work, and the tray 3 is continuously pushed to move through the displacement plate 436. In this process, the guide rail 438 and the guide groove 439 are used for guiding. Then the second electric push rod 437 is controlled to retract. The displacement plate 436 pushes the tray 3 to move onto the conveying belt 441 and abut against the pulley 444. Then the fourth bidirectional motor 442 is controlled by the control panel 7 to work, so as to drive the conveying belt 441 to work, and move the tray 3 to the outside of the tray plate 2. The sixth bidirectional motor 64 is controlled by the control panel 7 to work, and the fifth screw rod 63 is driven to work, so as to drive the placing plate 61 to ascend and descend. The second position receiver 66 and the third position sensor 65 are used for cooperation to move the placing plate 61 to the corresponding position, so as to receive the tray 3 pushed out from the conveying belt 441. Then the placing plate 61 is controlled to ascend to a suitable height, so as to facilitate taking and placing goods on the placing plate 61.

[0078] When the tray 3 needs to be returned, the control panel 61 is controlled to return to the corresponding height, and then the third electric push rod 67 is controlled to work through the control panel 7, so that the tray 3 is pushed back to the conveying belt 441 through the returning plate 68. The fourth bidirectional motor 442 is controlled to reverse through the control panel 7, and the tray 3 is moved backward through the conveying belt 441 until it is moved to the farthest position. At this time, the fifth bidirectional motor 446 is controlled to work, driving the fourth lead screw 445 to rotate, so that the tray 3 is moved to the third bidirectional motor 433 through the conveying plate 424. In this process, the guide rail 438 and the guide groove 439 are guided, until the second magnet 418 abuts against the third magnet 435, and the third motor is controlled to reverse, so that the tray 3 is driven to abut against the first blocking strip 416 through the magnetic force. In this process, the limiting groove 425 moves to the upper side of the conveying plate 424. And the second bidirectional motor 423 is controlled to reverse, so that the tray 3 is returned through the conveying plate 424 and the limiting groove 425. The pushing frame 412 is controlled to move to the position of the tray 3 on the pushing groove 411, and then the first electric push rod 415 is controlled to work, limiting the tray 3, and then the tray 3 is returned through the pushing frame 412, realizing the taking and placing of goods.

[0079] When the tray 3 moves on the tray 2, the probe head 52 detects the presence of the sensing area 51, so as to feed back a signal to the control panel 7, facilitating operation through the control panel 7. At the same time, in cooperation with each motor and electric push rod, the position and state of the tray 3 are monitored in real time, preventing misoperation or loss.

[0080] In this process, the goods are placed on the isolation pad 9, and the weight of the goods in the tray 3 can be monitored in real time through the pressure sensor 8 and the isolation pad 9, ensuring accurate tracking of the state of the goods. The electrical elements in the cabinet 1 are controlled through the control panel 7, and the control process and time are transmitted to the data cloud, so as to generate detailed inventory reports and prediction models by using big data analysis technology, optimize inventory management strategies, and monitor the position and state of the tray 3 in real time.
