The present invention relates to an integrated sorting method for cigarettes with several specifications on the basis of a multi-stage classification method. The sorting method includes: dividing the cigarettes to be sorted into the following main categories: cigarettes with standard specification, cigarettes with standard specification in small quantities and cigarettes in special shapes; Dividing the cigarettes into special shapes in standard slim cigarettes and cigarettes in ultra special shapes depending on size; Feeding the cigarettes to be sorted into different sorting lines according to corresponding categories: feeding the cigarettes with standard specification into a primary sorting line in order to obtain a first sub-category; Feeding the standard specification cigarettes in short supply to a secondary sorting line to obtain a second sub-category; Feeding the standard slim cigarettes into a slim sorting line to obtain a third sub-category; Feeding the cigarettes in ultra-special shapes into a sorting line for ultra-special shapes in order to obtain a fourth sub-category; and merging the first, second, third and fourth subcategories of the same customer order to obtain a complete customer order. The present invention employs a multi-level classification method and applies various categories of cigarettes to different sorting lines in order to balance the workload of the sorting lines, achieve the most efficient sorting, and improve the sorting quality.
