Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
As shown in fig. 1, the method for accurately controlling the circumference of a cigarette provided by this embodiment specifically includes the following steps in an actual execution process:
and step S1, setting a dial on the knob of the large pressure plate.
Specifically, according to the clock scales, a dial which is surrounded by 60 scales to form a circle is pasted on the knob of the large pressure plate. After the dial is pasted, the large pressing plate can be adjusted more accurately.
And step S2, estimating the circumferential deviation degree in the cigarette rolling process according to the online detection result of the circumference by adopting an exponential weighting estimation method to obtain the estimated value of the process deviation.
In some embodiments of the present invention, the process deviation estimate at time t is calculated by the following equation,
wherein, X t Is a measuring circumference value for online detection at the current moment T, wherein T is a target circumference value, lambda is more than 0 and less than or equal to 1 is a weighting coefficient,
is the estimated value of the process deviation at the last detection time t-1, and the initial value thereof
The circumferential measurement value is a measurement of the circumference of a cross section of a cigarette. For the step-type abnormal fluctuation appearing on the circumference, the value of lambda can be larger, so that the weight of the latest detection result is larger, and the sensitivity of deviation estimation to new change appearing in the process is improved; and for the trend change appearing on the circumference, the value of lambda can be smaller, so that the slow change trend in the process can be expressed through weighted accumulation, and the accuracy of estimating the trend deviation is improved. Since step deviations are easier to identify and trend deviations are often difficult to find, the present invention may select a smaller weighting factor in a specific implementation, and may take λ ═ 0.2 as an example.
And step S3, constructing a judgment value of process fluctuation according to the estimated value of the process deviation.
Specifically, a discrimination value of process fluctuation is constructed using an accumulation sum function according to the estimated value of the process deviation.
In a specific implementation, the discrimination value of the process fluctuation is constructed by the following formula:
wherein Q is t + A discrimination value of positive fluctuation of the process, i.e. increase of the circumference, the initial value Q of which 0 + Is 0, Q t - A discrimination value of a negative process fluctuation, i.e. a decrease in circumference, the initial value Q of which 0 - Is 0.
And step S4, dynamically controlling the large pressure plate according to the judgment value of the process fluctuation.
In particular, according to Q t + And Q t - The size of the large pressure plate is dynamically controlled. Therefore, accurate control of the circumference can be realized, and a segmented control strategy can be adopted. In an embodiment of the method for accurately controlling the circumference of a cigarette, the step S4 may specifically include:
step S41, if 0 is taken as the center, within the range of +/-0.5, namely Q t + < 0.5 and Q t - When > -0.5, the abnormal deviation does not exist in the process, the circumference control is stable, and the large pressure plate is kept unchanged;
step S42, if Q is more than or equal to 0.5 t + If the value is less than 1, determining that a small degree of forward deviation exists in the process, tightening the large pressing plate, and adjusting the knob of the large pressing plate to the right by 5 scale values;
step S43, if-1 is less than or equal to Q t - If the value is less than-0.5, determining that a small degree of negative deviation exists in the process, loosening the large pressing plate, and adjusting the knob of the large pressing plate to the left by 5 scale values;
step S44, if Q is more than or equal to 1 t + If the value is less than 1.5, determining that a certain degree of forward deviation exists in the process, tightening the large pressing plate, and adjusting the knob of the large pressing plate by 10 scale values rightwards;
step S45, if-1.5 is less than or equal to Q t - If the value is less than-1, determining that a certain degree of negative deviation exists in the process, loosening the large pressing plate, and adjusting the knob of the large pressing plate to the left by 10 scale values;
step S46, if Q is more than or equal to 1.5 t + If the value is less than 2, determining that a larger degree of forward deviation exists in the process, tightening the large pressing plate, and adjusting the knob of the large pressing plate to the right by 15 scale values;
step S47, if-2 is less than or equal to Q t - If less than-1.5, determining that a large-degree negative deviation exists in the process, loosening the large pressure plate, and adjusting the knob of the large pressure plate to the left by 15 scale values;
step S48, if Q t + If the deviation is more than 2, the obvious positive deviation exists in the process, the states of the equipment and the wearing parts are checked, and the cloth belt is replaced or the position of the cigarette tongue is adjusted in time;
step S49, if Q t - If < -2 >, the existence of a significant negative deviation is determined, and equipment is checked to adjust the small pressing plate, the cigarette tongue and the like.
Further, the cigarette circumference accurate control method further comprises the following steps:
and step S5, optimizing the adjustment amount through the statistical analysis of the adjusted circumferential variation data.
Specifically, for each adjustment strategy, circle detection data of 5-20min after the adjustment strategy is implemented for multiple times (for example, 5 times or more) is collected respectively for statistical analysis, the mean value of the circle data after multiple adjustments is set to μ, and a method for optimizing the adjustment amount is introduced in two cases below.
