The specific matching method of the loading and unloading device 110 and the buffer device 120 will be described in detail below.

In some embodiments, the handling device 110 may include a plurality of handling layers, the plurality of handling layers are spaced along the height direction of the handling device 110, and the buffer device 120 may include a plurality of buffer layers, the plurality of buffer layers are spaced along the height direction of the buffer device 120, the handling layers and the buffer layers may correspond to each other, the goods 200 to be sorted of the corresponding handling layers may enter the buffer of the buffer layers, and the sorted goods 200 in the buffer layers may enter the corresponding handling layers for loading.

It is understood that a plurality of loading and unloading levels can independently perform the picking operation from the transfer robot 140, and when the transfer robot 140 carries a plurality of goods 200 to be sorted, different loading and unloading levels can unload different goods 200, and similarly, when the sorted goods 200 are loaded into the transfer robot 140, a plurality of loading and unloading levels can respectively load and unload different goods 200 at the same time, so that the loading and unloading efficiency of the goods 200 can be improved.

The goods 200 can be quickly transferred by the mutually connected loading and unloading layers and the buffer layers, and different loading and unloading layers and different buffer layers do not interfere with each other, so that the multi-layer goods 200 on the buffer device 120 can be buffered and transmitted at the same time, and the logistics efficiency is improved.

Optionally, a goods taking manipulator may be disposed on the loading and unloading layer, the goods taking manipulator may extend from the loading and unloading layer and take down the goods 200 to be sorted on the transfer robot 140, or place the sorted goods 200 on the transfer robot 140, the goods taking manipulator may be a clamping type manipulator, a lifting type manipulator, or a push-pull type manipulator, the goods taking structure of the specific manipulator is the prior art, and details are not repeated here.

In this example, the specific work tasks of the plurality of loading and unloading levels are not particularly limited, and the loading and unloading operations of the plurality of loading and unloading levels may be performed simultaneously, or the plurality of loading and unloading levels may be grouped, and a part of the loading and unloading levels may be subjected to the loading operation at the same time as the part of the loading and unloading levels is subjected to the loading operation.

In some embodiments, each buffer level may include a transition area 121, a discharge buffer area 122 and an upper cargo buffer area 123, and the loading and unloading levels may be interfaced with the transition area 121, that is, each loading and unloading level is interfaced with the transition area 121 of its corresponding buffer level, so that each buffer level can independently perform the transportation and storage of the cargo 200, and the transition area 121 serves as an intermediary area to avoid confusion or interference between the loaded cargo 200 and the unloaded cargo 200.

It can be understood that the buffer layer has a certain storage space for storing the goods 200, the unloading buffer area 122 is used for buffering the goods 200 to be sorted output from the loading and unloading device 110, the loading buffer area 123 is used for buffering the sorted goods 200 to be fed into the loading and unloading device 110, the unloading buffer area 122 and the loading buffer area are relatively independent, and the circulation paths of the goods 200 to be sorted and the sorted goods 200 in the two areas do not generate cross interference.

The transition area 121 serves as an intermediate area, the goods 200 to be sorted output from the loading and unloading device 110 need to enter the unloading buffer area 122 through the transition area 121, and the sorted goods 200 in the loading buffer area 123 need to enter the loading and unloading device 110 through the transition area 121, so that the unloading operation of the loading buffer area 123 and the loading operation of the unloading buffer area 122 on the same layer can be staggered to avoid interference between the routes of the unloading and loading.

Optionally, the unloading buffer area 122, the transition area 121, and the loading buffer area 123 may be sequentially arranged along the length direction of the buffer layer, that is, the unloading buffer area 122, the transition area 121, and the loading buffer area 123 are respectively arranged from one end to the other end of the buffer layer, so that the buffer layer is reasonably arranged along the straight line direction, and the space utilization rate is improved. The handling device 110 may be located on the side of the buffer layer in the extending direction and opposite to the transition region 121.

For example, each of the unloading buffer area 122 and the loading buffer area 123 may include a plurality of buffer locations, each of which may store a certain number of the goods 200, and may be one or more, the buffer locations are arranged along an extending direction of the buffer layer, and when the goods 200 to be sorted are conveyed to the sorting conveying line and the sorted goods 200 are conveyed to the loading and unloading device 110, the goods 200 may be sequentially output according to an arrangement order of the buffer locations.

It should be noted that, during the operation of the logistics sorting system 100, there may be a case where the quantity of the goods 200 to be sorted is large or the quantity of the goods 200 after being sorted is large, it may be desirable to have either the unload buffer 122 or the load buffer 123 store a certain amount of cargo 200 to increase system redundancy, for example, when the sorting conveyor 130 is performing the sorting operation, the partial sorting locations are maintained, at which time the sorting rate is reduced, the discharge buffer 122 is required to store a certain amount of the goods 200 to be sorted, so that the efficiency of feeding the goods 200 to be sorted into the sorting conveyor 130 is reduced, in order to avoid the jam during the sorting and transporting process of the goods 200, for example, the robot for delivering the goods 200 has a higher priority temporary task, and at this time, the handling device 110 cannot immediately deliver the sorted goods 200, and the loading buffer 123 is required to store a certain amount of sorted goods 200. The specific number of the buffer positions of the unloading buffer 122 and the loading buffer 123 and the size of the storage space may be set according to the type of the sorted goods 200 and the sorting efficiency of the sorting conveyor 130, and the number of the buffer positions may be one, two or more, which is not specifically limited in this embodiment.

It can be understood by those skilled in the art that the above-mentioned multi-layer structure of the plurality of loading and unloading layers of the loading and unloading device 110 and the multi-layer structure of the plurality of buffer layers of the buffer device 120 are for the purpose of multi-way picking, placing and transporting of the goods 200 to improve the logistics efficiency, and for example, the number of the loading, unloading and buffer layers may be two, three, four, five, six, seven, eight or more, and the number of the layers may be set according to the shipment volume of the handling robot 140, so that the space of each layer of the loading and unloading device 110 can be fully utilized while the picking, placing and transporting operations can be completed at one time, and the number of the layers of the loading, unloading device 110 and buffer device 120 can be set according to the sorting efficiency of the goods 200 by the sorting and transporting device 130, and the sorting efficiency is higher, and the number of the layers of the loading, unloading device 110 and buffer device 120 can be set more. The specific number of the loading and unloading layers and the buffer layers is not limited in the embodiment of the application.
