Method for inspecting cigarette rolling quality stability in cigarette processing

Abstract

The invention provides a method for inspecting the cigarette rolling quality stability in cigarette processing. The method is characterized in that a multivariate control chart tool in a statistical process control method is used for inspecting the integral rolling quality stability of a plurality of physical index expressions of the cigarettes. According to the method, the multivariate statistical process control theory is used, firstly, the controlled historical data estimation is carried out to obtain mu0 and Sigma0, then, x<2> and the absolute value of S statistical quantity for control are calculated according to the field collection data, and the deviation condition of the multi-index average value vector from the standard value and the sample in-group dispersing degree in the cigarette processing process can be controlled, so that the combined monitoring of a plurality of quality feature variables is realized, and the integral quality stability of the cigarette rolling integral process can be reasonably evaluated. The method has the important significance on improving the cigarette physical quality and improving the stability of the cigarette rolling process.

Description

technical field [0001] The invention relates to a method for inspecting the stability of rolling quality of processed cigarettes, specifically referring to a method for inspecting the stability of comprehensive rolling quality characterized by multiple physical indicators of cigarettes by using the multivariate control chart tool in the statistical process control method . Background technique [0002] With the increasing requirements of consumers on the quality of cigarettes, more stringent requirements are put forward for the stability of cigarette rolling quality. Cigarettes are a typical quality multi-characteristic product. The physical indicators controlled in the rolling process include weight, hardness, draw resistance, circumference and many other quality characteristic parameters, and the quality characteristics are interrelated and jointly affect product quality. At present, in the packaging process, the control problem of multiple quality characteristic paramete...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing methods cannot jointly monitor the physical indicators of cigarettes during the rolling process, resulting in the inability to effectively test the stability of the comprehensive physical quality of cigarettes, and provide a method that can simultaneously reflect multiple qualities during the rolling process. A test method for the fluctuation of characteristic variables, in order to provide scientific and effective guidance for improving the stability of the cigarette rolling process and improving the comprehensive quality of cigarettes
