First channel-dividing device sorts quick despatch, so that each alignment area of second order station only has in vertical direction One quick despatch；

Preceding backflow station receives the quick despatch of the first channel-dividing device sorting；

Transport device transfers the quick despatch after the sorting of the first channel-dividing device to scanning means；

Barcode scanning device is scanned and preserves to the quick despatch of alignment area；

Control device judges whether to meet sorting condition according to the barcode scanning result of scanning means；

If so, control device, which controls the second channel-dividing device, elapses quick despatch to going out part station；

If it is not, then the transport device quick despatch that does not sort of transfer is to rear backflow station.

7. express delivery method for sorting according to claim 6, which is characterized in that the transport device divides quick despatch Choosing, so that only there are one quick despatch steps in the horizontal direction for each alignment area of first order station, including：

The first sensor detection quick despatch of first order station concurrently send testing result to control device；

Control device controls the motor of first order station drive component according to the testing result of first order station, so that often Only there are one quick despatch in the horizontal direction for a alignment area.

8. express delivery method for sorting according to claim 6, which is characterized in that first channel-dividing device carries out quick despatch Sorting, so that each alignment area of second order station is in vertical direction, only there are one quick despatch steps, including：

The first sensor detection quick despatch of second order station concurrently send testing result to control device；

Control device judges that each alignment area is in the quick despatch quantity of vertical direction according to the testing result of second order station It is no to be more than 1；

If so, control device controls the quick despatch on the first channel-dividing device passage second order station to preceding backflow station, with So that each alignment area of second order station is in vertical direction, only there are one quick despatch, into next step；

If it is not, being then directly entered in next step.

9. express delivery method for sorting according to claim 6, which is characterized in that it is described if it is not, then transport device transfer do not divide The quick despatch picked further includes after step to rear backflow station：

After described after the transfer of reflux conveyer belt the quick despatch of backflow station to third buffer area；

Alternatively, the preceding backflow station receives the quick despatch of the first channel-dividing device sorting, further include after step：

Before described before the transfer of reflux conveyer belt the quick despatch of backflow station to separator.

10. express delivery method for sorting according to claim 6, which is characterized in that described if so, control device control second Channel-dividing device elapses quick despatch to going out part station step, including：

If so, the second push piece mechanism information that control device prestores according to the barcode scanning result queries and confirmation of scanning means；

The counting component counts the quick despatch for reaching feeding station and sends counting and instructed to control device,

The counting instruction includes sign on and the instruction of real-time step number；
