[0002] Cargo storage adopts a stereoscopic shelf. The stereoscopic shelf is a multi-layer structure, and the cargo is placed on the layer shelf. The cargo is of different sizes and weights, and sufficient space is required between the layer shelves. Although the layer shelf can bear the cargo and prevent the upper cargo from pressing the lower cargo, the existence of the layer shelf leads to space waste. In practice, large cargo and heavy cargo adopt solid outer packaging, and small cargo and light cargo adopt thin outer packaging. Therefore, the cargo is classified by weight, the heavy cargo is placed at the bottom, the light cargo is placed at the top, the heavy cargo bears the light cargo, and the layer shelf is not required, so that the storage space can be fully utilized.

[0003] In express warehousing, the cargo generally needs to be sorted. In order to improve the sorting efficiency, full-automatic sorting has been realized in the prior art, but the sorting in the prior art only sorts the cargo according to the region, and all the sorted cargo is transported in sequence after sorting, which will cause the small and light cargo to be placed at the bottom of the truck box and the heavy and bulky cargo to be placed at the top of the truck box during loading, which will squeeze and deform the cargo and is not conducive to the stability of the cargo. Therefore, in order to improve the stability of the cargo loading, the loading personnel generally selectively place the heavy cargo in the lower space in the truck box in the prior art, but this operation requires the worker to roughly estimate the weight of the cargo, which greatly increases the working intensity of the worker during loading and reduces the working efficiency (authorized announcement No. CN219003795U, a sorting device applied in intelligent warehousing, the background technology part of the specification).
