It should be noted that the structures of the storage device 10 and the shelf 30 may be the same or similar. The first stock detector 11 and the second stock detector 31 may have the same configuration and the same principle.

According to the replenishment device 100 provided by the embodiment of the invention, the working principle of the replenishment device 100 is as follows:

when the second stock detector 31 detects a shortage or lack of stock on the shelf 30, it feeds back a signal to the control device, which controls the transport vehicle 20 to transport the goods 101 in the storage device 10 onto the shelf 30. When the second stock detector 31 detects a lack or lack of stock in the storage apparatus 10, it alarms to alert the merchant to timely restock.

Specifically, when loaded from within the storage device 10.

When a certain cargo 101 needs to be transported, the control device analyzes the detection signal of the first stock detector 11 (when the cargo 101 is placed on a certain storage object 12, information of the cargo 101 is input into a database in the control device), the cargo 101 is located in one of the storage objects 12, the control device controls the transport vehicle 20 to reach the storage object 12 under the guidance of the track element 40 and enter the accommodating cavity 120 through the bottom 121, when the magnetic resistance sensor 16 detects that the preset magnetic field intensity is met, the control device controls the transport vehicle 20 to pause and controls the driving element 14 to enable the support object 13 to slide downwards, and in the process of sliding the support object 13, the cargo 101 enters the clamping space 220 from the bearing space 130, and the fixing device 22 firmly clamps the cargo 101. The control device controls the transport carriage 20 to transport it to the shelf 30.

The storage device 10 is identical in construction to the shelves 30 and requires unloading. The structure of the storage device 10 is described as how the discharge is accomplished.

When the carrier 20 enters the accommodating cavity 120 through the bottom 121 and the magnetic resistance sensor 16 detects the preset magnetic field intensity, the carrier 20 pauses, at this time, the supporting object 13 is relatively close to the bottom 121, the control device controls the driving part 14 to drive the supporting object 13 to slide upwards, in the upward sliding process, the bearing part 131 of the supporting object 13 abuts against the goods 101 and makes the goods 101 separate from the fixing device 22, when the supporting object 13 is far away from the fixing device 22, the suspending of the goods 101 is realized, and the goods 101 enter the bearing space 130 to realize temporary storage.

The first stock detector 11 and the second stock detector 31 detect the presence or absence of the goods 101 in the goods storage device 10 and the goods 101 on the shelf 30, and the information of the goods 101 may be preset in a database in the control device, so as to judge which goods 101 are out of stock or are out of stock in time. And the real-time supplement is realized through the transport vehicle 20, the whole equipment is stable in operation, the design is ingenious, and the use effect is better.
