Problems solved by technology
For the reliability and accuracy of the cigarette short detection instrument, it can only be judged by the experience of the staff, and cannot be judged scientifically.
Due to the inability to scientifically adjust and maintain the cigarette short detection instrument in time, there has always been a large potential quality risk in the production process, which often leads to the emergence of a large number of unqualified products, resulting in a large amount of economic losses for the enterprise

Embodiment Construction
[0016] Such as figure 1 As shown, the method for judging the reliability of a cigarette short detection instrument for a cigarette maker according to the present invention includes the following steps
[0017] A: Record the number of internal empty head rejections and the number of external empty head rejections displayed on the industrial control display of the cigarette machine every N minutes, and perform manual statistics on the number of internal empty heads and the number of external empty heads in the empty waste bin;
[0018] B: Every N minutes, the number of cigarettes that are not less than 7000 cigarettes that have been tested by a cigarette empty detection instrument are drawn for manual inspection, and the collected cigarettes that have been tested by the cigarette empty detection instrument but have not been detected are recorded. Quantity and the number of empty cigarettes discharged;
[0019] C: Repeat step A and step B M times, M is not less than 6;
[0020] D: Match ...

The invention discloses a method for judging the reliability of a cigarette empty end detection instrument provided with a cigarette machine by using "hypothesis test" and a six sigma judgment method. The quantity and the number of empty ends removed from the empty end, at the same time, the number of empty end cigarettes inside the empty end waste box and the number of empty end cigarettes discharged outside are manually counted, and the data are paired sample t-test; The detected number of internal empty cigarettes and the number of external empty cigarettes will be calculated to obtain the internal empty rate and external empty rate after detection by the cigarette empty detection instrument and converted to the sigma level, with the help of "hypothesis test" And the six sigma judgment method, based on data analysis, accurately, objectively and effectively realizes the judgment of the reliability and accuracy of the cigarette empty end detection instrument that comes with the existing cigarette machine, and avoids the economic loss caused by the downtime detection.
Description
Technical field [0001] The invention relates to a cigarette quality measuring instrument analysis method, in particular to a method for judging the reliability of a cigarette empty detection instrument of a cigarette maker. Background technique [0002] According to Part 3 of "National Cigarette Standards of the People's Republic of China" GB5606.3-2005 on "Packaging, Rolling Technical Requirements and Storage and Transportation Regulations": The short end of the cigarette belongs to the quality defect of Class A, that is, the end of the cigarette should not be hollow. Hollow loose with a depth greater than 1mm and a hollow section greater than 2 / 3. In the actual production process, due to the impact of various factors such as the quality of tobacco shreds and cigarette equipment, short ends are one of the most frequently occurring quality defects in the cigarette manufacturing process. In the process of cigarette production, the production rate of cigarettes reaches 8,000 cigar...
