Description

Technical Field

[0001] The invention belongs to the technical field of cigarette fly ash detection, and relates to a method for detecting cigarette fly ash, and in particular to a detection device and a detection method for quantitative analysis of cigarette fly ash amount. Background Art

[0002] With the development of cigarette technology and the continuous improvement of consumers' requirements for cigarette smoking quality, the quality of cigarette burning and ash performance during the smoking process has attracted more and more attention from consumers. At the same time, since the ash falling during the smoking process also pollutes the environment and consumers' clothes, how to improve the burning and ash performance of cigarettes has always been one of the important research directions of the tobacco industry.

[0003] At present, the research method of cigarette burning ash performance is mainly to compare and evaluate the ash setting effect of the ash column formed after the cigarette is left to burn. It should be noted that the current method evaluates the ash performance of cigarettes statically through static combustion or under smoking conditions, while consumers are concerned about the quality of cigarette ash during the smoking process. It can be seen that the current method can only compare and evaluate the overall ash column of cigarettes after combustion, and then guide the improvement of cigarette ash performance quality, but it cannot objectively reflect the fly ash situation of cigarettes during the smoking process, and the amount of fly ash caused by consumers' ash flicking operations during the smoking process.

[0004] Fly ash may pollute the environment and consumers' clothes, and cause disgust among surrounding non-smokers. It can be seen that it is of great significance to study the reduction of fly ash in the cigarette smoking process based on consumer demand and safety.

[0005] Based on the inadequacy of existing detection technology, and due to the characteristics of fly ash index during cigarette combustion, such as high measurement accuracy, large number of measurement samples, and short duration of fly ash state, it is difficult to detect manually. Therefore, it is necessary to develop detection equipment suitable for cigarette manufacturing and cigarette fly ash characteristics.

[0006] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art. The present invention first proposes a cigarette fly ash index. The cigarette combustion fly ash during the smoking process includes two parts. The first part is the ash that separates from the cigarette ash column during the smoking movement (non-ash flicking process); the second part is the ash that does not fall into the ash collection box (ashtray in the actual process) during the ash flicking process and is separated from the ash column.

[0008] Furthermore, the present invention proposes a detection device and a detection method for quantitative analysis of the amount of cigarette fly ash. The method is a quantitative detection method for cigarette fly ash during the cigarette smoking process, the cigarette smoking movement process and the ash flicking process, that is, the characterization of the situation where the cigarette ash separates from the ash column and falls and scatters. Machine vision is used to track the cigarette burning state in real time, and image processing is used to track and judge the situation of cigarette fly ash. By objectively and accurately characterizing the cigarette fly ash indicators, it is used to guide cigarette formula research and quality optimization and upgrading.

[0028] Step (3), repeating the cigarette movement smoking and cigarette ash flicking operations according to the smoking mode until the cigarette reaches a set length, and then stopping the cigarette movement smoking and cigarette ash flicking operations;

[0029] Step (4), using the image acquisition unit 4 to acquire in real time the image of the cigarette fly ash on the fly ash collection plate 21 before each ash flicking, and the corresponding image of the cigarette fly ash on the fly ash collection plate 21 after the ash flicking, and transmit the acquired images to the image processing unit;

[0032] Wherein step (4) and step (5) are carried out during step (1) to step (3).

[0033] The calculation method of step (5) is:

[0034] (51) Amount of cigarette fly ash A1n during the Nth cigarette movement and smoking process: Subtract the N-1th cigarette fly ash image after the ash flicking from the Nth cigarette fly ash image before the ash flicking to obtain the increment of the cigarette fly ash falling on the fly ash collecting plate 21 during the Nth cigarette movement and smoking process. After grayscale processing and binarization processing are performed on the subtracted image, the fly ash area in the image is calculated, which is the amount of cigarette fly ash A1n during the Nth cigarette movement and smoking process;

[0035] (52) Amount of cigarette fly ash A2n during the Nth cigarette ash flicking process: The Nth cigarette fly ash image after ash flicking is subtracted from the Nth cigarette fly ash image before ash flicking to obtain the increment of cigarette fly ash falling on the fly ash collecting plate 21 during the Nth cigarette ash flicking process.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. The present invention first proposes a cigarette fly ash index. The cigarette combustion fly ash during the smoking process includes two parts.

The present invention combines the fly ash area of ​​the cigarette during the smoking movement and the ash-flicking process as an indicator of the cigarette fly ash amount. Further, the present invention proposes a detection method for quantitative analysis of the cigarette fly ash amount. The method is a quantitative detection method for cigarette fly ash during the smoking process, the smoking movement process and the ash-flicking process of the cigarette, that is, the characterization of the situation of cigarette ash separating from the ash column and falling and scattering.

In the present invention, the image acquisition unit 4 firstly acquires the image of cigarette fly ash on the fly ash collection plate 21 before each ash flicking, and the corresponding image of cigarette fly ash on the fly ash collection plate 21 after ash flicking in real time, and transmits the acquired image to the image processing unit; the image processing unit compares and analyzes the received cigarette fly ash image, calculates the amount of cigarette fly ash A1 in the process of cigarette movement smoking, and the amount of cigarette fly ash A2 in the process of cigarette ash flicking; and the sum of A1 and A2 is the amount of cigarette fly ash A in the process of simulated human body smoking of the cigarette. After the sample batch detection is carried out according to the required number of tests, the cigarette combustion fly ash index of the batch of samples can be obtained by calculation, the cigarette fly ash quality is evaluated, and product research and improvement are guided.

[0042] 3. The present invention provides a cigarette fly ash detection device based on machine vision, and establishes a set of cigarette fly ash detection devices based on the simulation of human cigarette smoking process.

A detection method for quantitative analysis of cigarette fly ash, using the detection device according to any one of claims 1 to 5 for measurement, characterized in that: The steps include: Step (1), clamping a cigarette on a cigarette holder (12), lighting the cigarette on the cigarette holder (12), and starting a manipulator (11) simulating human smoking to simulate smoking the cigarette according to a set smoking mode, wherein fly ash generated during the simulated smoking process falls on the fly ash collecting plate (21); Step (2), according to the smoking mode, the simulated smoking process also includes an ash flicking process, wherein the cigarette is knocked / tapped by the ash flicking unit (3) so that the ash of the cigarette combustion ash column falls off and is collected in the ash collection box (33); the fly ash generated in the ash flicking process falls on the fly ash collection plate (21); Step (3), repeating the cigarette movement smoking and cigarette ash flicking operations according to the smoking mode until the cigarette reaches a set length, and then stopping the cigarette movement smoking and cigarette ash flicking operations; Step (4), collecting, in real time, through the image acquisition unit (4), an image of cigarette fly ash on the fly ash collection plate (21) before each ash flicking, and a corresponding image of cigarette fly ash on the fly ash collection plate (21) after the ash flicking, and transmitting the collected images to the image processing unit; Step (5), the image processing unit compares and analyzes the received cigarette fly ash images, and calculates the cigarette fly ash amount A1 during the cigarette smoking process and the cigarette fly ash amount A2 during the cigarette ash flicking process; The sum of A1 and A2 is the amount of cigarette fly ash A during the simulated human smoking process of the cigarette; Wherein step (4) and step (5) are carried out during step (1) to step (3).

7. The detection method for quantitative analysis of cigarette fly ash according to claim 6, characterized in that: The calculation method of step (5) is: (51) Amount of cigarette fly ash A1n during the Nth cigarette movement smoking process: Subtract the N-1th cigarette fly ash image after the ash flicking from the Nth cigarette fly ash image before the ash flicking to obtain the increment of the cigarette fly ash falling on the fly ash collecting plate (21) during the Nth cigarette movement smoking process. After grayscale processing and binarization processing are performed on the subtracted image, the fly ash area in the image is calculated, which is the amount of cigarette fly ash A1n during the Nth cigarette movement smoking process; (52) Amount of cigarette fly ash A2n during the Nth cigarette ash flicking process: Subtract the Nth cigarette fly ash image before the ash flicking from the Nth cigarette fly ash image to obtain the increment of cigarette fly ash falling on the fly ash collecting plate (21) during the Nth cigarette ash flicking process. After grayscale processing and binarization processing are performed on the subtracted image, the fly ash area in the image is calculated, which is the amount of cigarette fly ash A2n during the Nth cigarette ash flicking process; According to the above process, the amount of cigarette fly ash during each cigarette motion smoking process and the amount of cigarette fly ash during each cigarette ash flicking process are calculated, and the accumulation is the cigarette fly ash amount A during the cigarette simulated human body smoking process.
