Method and system for precise marking of cigarettes

Abstract

The invention belongs to the technical field of cigarette sorting, and discloses a method and system for precise coding of cigarettes. The method includes: buffering the cigarettes sorted to households; carrying out high-speed to low-speed differential conveying of the cigarettes; accurately positioning the cigarettes; and marking the cigarettes. The system includes a buffer mechanism, a differential conveying mechanism, a coding conveying mechanism and a coding mechanism. The four mechanisms are arranged in sequence. The conveying line and the low-speed conveying line adjacent to the coding conveying mechanism; the coding conveying mechanism includes a coding conveying line and a positioning device arranged on the coding conveying line. In the present invention, through the buffering, differential speed conveying and precise positioning of the cigarettes, the distance between the cigarettes is uniform and the posture of the cigarettes is adjusted, thereby ensuring the accuracy of the coding position.

Description

technical field [0001] The invention relates to the technical field of cigarette sorting, in particular to a method and system for precise coding of cigarettes. Background technique [0002] Tobacco products belong to the state monopoly, and it is necessary to carry out logistics tracking on all aspects of its production, sales, inventory, etc., so as to achieve effective control. As the core component of tobacco logistics, the cigarette sorting system undertakes the important task of coding and marking the cigarettes on the sorting line. The accuracy of the coding and marking of the cigarettes must be guaranteed in order to better realize logistics tracking. [0003] The cigarette sorting system first sorts the cigarettes to households according to the needs of different customers for the types of cigarettes, and then performs coding, inspection and packaging operations. The sorting equipment is arranged on the side of the sorting line, and the cigarettes pop out from the ...

AI Technical Summary

Problems solved by technology

The sorting equipment is arranged on the side of the sorting line, and the cigarettes pop out from the sorting equipment and fall on the sorting line. Since the sticks pop out at a certain speed, and the sorting line also runs at a certain speed, they fall on the Cigarettes on the sorting line will have problems such as incorrect smoke posture and uneven spacing, which will lead to problems such as subsequent coding errors, missing codes, and poor coding effects

[0004] At the same time, the sorting system itself does not have the function of checking the quantity and type of cigarettes sorted into households, and any mistakes will cause irreparable losses

[0005] In addition, when the existing cigarette sorting system is coding the cigarettes, the information representing a certain kind of cigarette in the code segment assigned to each household can only identify the order of the cigarette on the sorting line, but cannot accurately Specific information such as the variety of cigarettes is not convenient for follow-up logistics tracking
