Embodiment Construction

[0016] like figure 1 As shown, the method for judging the reliability of the cigarette machine cigarette empty end detection instrument according to the present invention comprises the following steps

[0017] A: Every N minutes, record the number of inner empty ends and outer empty ends removed displayed on the industrial control display of the cigarette machine, and at the same time manually count the number of inner empty end cigarettes and outer empty end cigarettes in the empty end waste box;

[0018] B: At intervals of N minutes, not less than 7,000 cigarettes that have been detected by the short-end detection instrument are selected for manual inspection, and the extracted cigarettes that have been detected by the short-end detection instrument but have not been detected are recorded. Quantity and number of empty cigarettes discharged outside;

[0019] C: Repeat step A and step B M times, M not less than 6;

[0020] D: The number of empty ends removed from the inner e...

Abstract

The invention discloses a method for determining the reliability of a cigarette loose end detector that comes with a cigarette maker by hypothesis test and six sigma method, characterized by collecting an internally-discharged cigarette loose end rejecting amount and an externally-discharged cigarette loose end rejecting amount which are displayed by a cigarette maker industrial control display within the required time, simultaneously manually counting the amount of the internally-discharged cigarette loose ends and the amount of the externally-discharged cigarette loose ends in a cigarette loose waste tank, carrying out paired samples T test on the data; simultaneously according to the amounts of internally-discharged cigarette loose ends and externally-discharged cigarette loose ends which are not detected by the cigarette loose end detector, converting the internally-discharged cigarette loose end rate and externally-discharged cigarette loose end rate which are calculated by being detected by the cigarette loose end detector into a Sigma level. According to the invention, by means of hypothesis test and six sigma determination method, based on data analysis, the determination of the reliability and accuracy of the cigarette loose end detector that comes with the cigarette maker is realized accurately, objectively and effectively, thus the economic loss caused by shutdown detection is avoided.

Description

technical field [0001] The invention relates to an analysis method of a cigarette quality measuring instrument, in particular to a method for judging the reliability of a cigarette machine empty end detection instrument. Background technique [0002] According to the "National Standards of the People's Republic of China on Cigarettes" GB5606.3-2005 Part 3 on "Packaging, Rolling Technical Requirements and Storage and Transportation Regulations": the empty ends of cigarettes are class A quality defects, that is, there should be no hollows at the ends of cigarettes Voids with a depth greater than 1mm and a hollow section greater than 2 / 3. In the actual production process, due to the influence of various factors such as the quality of shredded tobacco and cigarette equipment, short ends are one of the quality defects that occur frequently in the production process of cigarettes. In the cigarette production process, the production speed of cigarettes reaches 8,000 cigarettes per...
