As shown in the attached Figure 1 figures, it includes a cross-belt sorter 100, and the cross-belt sorter 100 includes tracks, a circle of sorting trolleys 110 connected in sequence arranged on the tracks, and a driving device for driving the sorting trolleys 110 to move along the tracks. The specific structure of the cross-belt sorter 100 is known technology and is not an innovation of the present utility model, so it will not be elaborated here.

[0026] As shown in the attached Figure 1 figures, a grid area 200 and a bag supply area 300 are provided on the side of the cross-belt sorter 100. The grid area 200 and the bag supply area 300 are distributed on both sides of the linear extension section of the cross-belt sorter 100. Each side of the grid area 200 includes a row of sorting grids 210, and each bag supply area 300 includes multiple bag supply platforms 310. The specific structures of the sorting grids 210 and the bag supply platforms 310 are known technology and are not an innovation of the present utility model, so they will not be elaborated here.
