and/or each group of belt lines consists of a plurality of small belt lines which are connected end to end; each small belt line is provided with a speed reducing motor, and the speed reducing motor is also provided with a frequency converter.

10. Method of operating a loop order sorter system according to any of the claims 1-9, comprising:

before sorting the loop lines, manually placing a charging basket to the head of the belt line at the initial end, conveying the belt line in a counterclockwise and forward direction under the driving of a motor, and stopping rotation of the conveying line after the charging baskets of the belt line corresponding to the blanking port are filled;

when the loop is sorted, the annular transmission chain travels anticlockwise along the loop, when the turnover-type trolley needs to be triggered to overturn, the rejector is instantly lifted, when the turnover-type trolley passes through, the rear part of the turnover-type trolley gradually rises along the slope of the rejector, so that the tray is overturned, and the material is discharged from the discharging port; when the tray is tipped, the tray moves to the position of the reset guide strip, moves from the low position of the slope to the high position, and is gradually lifted by the reset guide strip from the tipping state, so that the reset of the tray is realized;

when the loop sorting is finished, the basket supplementing and returning conveying line is driven by the motor to transport clockwise and reversely, the basket returning action is completed, and the charging basket after returning is used for rechecking and weighing.
