Error-proof design for cigarette steel seal coding mode

The invention discloses an error-proof design for a cigarette steel seal coding mode. The design is characterized in that the product quality can be conveniently traced in the cigarette production process; and the quality tracing basis is mainly the product quality information of marks on the cigarette product package, and the mark content of the quality information generally comprises six types including the manufacturers, the year, the month, the date, the class, the machine and the like. The Poka-YoKE error-proof design in the Lean production is applied, the identification on six types of contents including manufacturers, the year, the month, the date, the class, the machine and the like can be realized by adopting four bits of codes, the field content of different bits of codes is unified, the code field is defined to be combinations of English letters and numbers, each bit of code comprises at most 36 fields, and the steel seal information mark content is added. The error-proof design provided by the inv
