Description
Technical Field
The application belongs to the technical field of cigarette manufacturing control, and particularly relates to a control method for cigarette weight balance.
Background
The balance of the weight of the cigarettes refers to that the density of the whole axial direction of tobacco shred parts of the cigarettes after the filter tip is removed is basically the same, and the problems that the hardness of the cigarettes is high due to overlarge weight of parts and the hardness of the cigarettes is low due to overlarge weight of parts and the quality of the cigarettes is affected are avoided.
At present, related tobacco enterprises at home and abroad need to detect the weight of cigarettes in the production process of the cigarettes so as to ensure that each cigarette can be in a set standard range, but some cigarettes sold are still unavoidable and some parts of the cigarettes are over-empty and some are over-hard, the reason is that the axial tobacco shred distribution of the cigarettes is uneven, in order to overcome the problem, the detection is carried out on the tobacco shreds at the ends of the cigarettes in the prior art, the detection has the advantages of convenient detection, and the problem that the tobacco shreds drop at the ends of the cigarettes can be solved while the uniformity of the tobacco shreds of the cigarettes is improved within a set density range, but the problem that the axial tobacco shreds of the cigarettes are unevenly distributed still cannot be solved.
Disclosure of Invention
The application aims to provide a control method for weight balance of cigarettes, which aims to solve the problems in the existing cigarette detection.
In order to achieve the above object, the present application is achieved by the following technical scheme;
a control method for cigarette weight balance comprises the following steps:
s1, determining the standard weight and standard density range of cigarettes to be detected;
s2, detecting the weight of the cigarette to be detected by using a weight detection system, comparing the weight with the standard weight, and if the weight of the cigarette to be detected is not in the standard weight range, entering a step S6;
s3, dividing the cigarette to be detected into N parts in the axial direction, wherein N is a natural number, and N is N1 to Nn respectively; wherein the part connected with the filter tip is N1, and the end far away from the filter tip is Nn;
s4, respectively detecting the densities of the N1 to the Nn parts by utilizing a microwave sensor, respectively obtaining the cigarette densities of the corresponding parts to be rho 1 to rho N, judging whether the difference value between rho 1 or rho N and the standard density is in a set range, if so, entering a step S5, otherwise, executing a step S6;

Further, the standard weight and standard density in the step S1 are determined according to different brands and different types of cigarettes.
Further, in step S2, if the weight of the cigarette to be detected is not within the standard range and continuously reaches the set time, a feedback signal is sent to the yarn feeder to adjust the yarn feeding amount of the yarn feeder.
Further, in step S4, each portion corresponds to one microwave sensor, or the same microwave sensor corresponds to a different portion of the cigarette and obtains different density signals.
Further, in step S4, when the preset range is exceeded and the preset time is reached, a feedback signal is fed to the wire feeder to adjust the wire feeding amount of the wire feeder.
Further, in step S5, the densities of the two adjacent parts are both less than the standard density and continuously reach the set time, and a feedback signal is fed to the wire feeder to adjust the wire feeding amount of the wire feeder.

Detailed Description
The following examples are given by way of illustration only and are not to be construed as limiting the scope of the application.
The technical scheme is a technical scheme provided on the basis of improvement of a weight control System (SRM) and a cigarette detection system (CIS) of the PT70 type cigarette making machine which are used at present, and is an improvement technology provided for the actual conditions of the cigarette in the actual production process at present.
In practical production or sales, each brand of cigarettes has a certain problem, namely the whole of the cigarettes meets the set standard, so that subsequent packaging and sales can be performed by the existing detection means, but one or more cigarettes usually exist, when the conventional hand pressure is used, different parts of the cigarettes are found to be different, namely the tobacco shreds are unevenly distributed, and although the tobacco shreds before rolling pass through the leveling disc to ensure the leveling of the tobacco shreds as much as possible, in practice, the tobacco shreds provided by the tobacco feeding machine still have conditions such as agglomeration, or uneven filament outlet of the planar part of the tobacco feeding machine or other reasons, and the total weight can meet the requirements, so that the cigarettes enter the next process through detection.
There are also techniques proposed at present as to how to ensure a uniform density of the cut tobacco in the axial direction of the cigarette, but the effect cannot be confirmed, and there is no specific detection technique for detecting the cigarette in this aspect.
As shown in fig. 1, the application provides a control method for weight balance of cigarettes, which comprises the following steps:
s1, determining standard weight and standard density range of cigarettes to be detected, wherein the data is usually determined before cigarettes of a certain brand and a certain model are produced, and the relevant parts of a cigarette machine, such as the cut tobacco feeding amount of a cut tobacco feeder, need to be adjusted according to the data in production.
Therefore, in actual detection, a balance may be used to measure the tobacco shred weight, or a microwave sensor may be used to measure the tobacco shred density of the tobacco shred, and then a shaft encoder is combined to determine the weight of a specific tobacco shred.
S2, detecting the weight of the cigarettes to be detected by using a weight detection system, such as the microwave sensor combined with an axial encoder or an electronic balance, wherein the specific weight detection is not in the specific protection of the application, and more specifically, the application does not require any conventional weight detection mode, such as the quantity of each sampling amount, so long as the weight of the cigarettes can be detected, the detected weight of the cigarettes can be compared with the standard weight, if the weight of the cigarettes to be detected is in the standard weight range, the cigarettes conforming to the standard are conveyed downwards on a conveying line, if the weight of the cigarettes to be detected is not in the standard weight range, the cigarettes to be detected are judged to be unqualified, and a rejection signal is sent to a rejection system through a control system to reject the cigarettes.
The technical scheme is different from the conventional cigarette weight detection in that if the weight of the cigarette to be detected is not in the standard range and continuously reaches the set time (the time can be set according to the needs, such as 10 seconds, 30 seconds, 60 seconds and the like, but generally cannot exceed 60 seconds, so that even a PT70 cigarette machine, the cigarette amount per minute is 10000 cigarettes/minute, if the time is too short, accidental phenomena caused by the agglomeration of the cut tobacco can be caused, but if the time is slightly long, the accidental phenomena are not caused by the agglomeration of the cut tobacco, but other factors are caused, and the unqualified cigarette rate can be increased, a feedback signal is fed to the cut tobacco feeder, and information prompt is carried out simultaneously so as to adjust the cut tobacco feeding amount of the cut tobacco feeder.
The key of the technical scheme is that the qualified cigarettes are further detected after detection, and the method can also comprise the further detection of cigarettes meeting the requirements after various detection means such as open mouth detection, empty head detection, air leakage detection, ventilation degree detection, suction resistance detection, OTIS detection and the like before the specific detection of the technology.
S3, dividing the cigarette to be detected into N parts in the axial direction, wherein N is a natural number, and N is N1 to Nn respectively; in the technical scheme of the application, the conventional cigarette is divided into more than three parts, otherwise, the density of cut tobacco cannot be accurately detected, and in the embodiment, the cigarette is axially divided into four parts, namely four parts are illustrated as examples, namely N1, N2, N3 and N4 respectively, wherein N4 is the end part of the cigarette. In other embodiments of the present application, the axial division of the smoke axis into several parts is determined according to the need, and the technical scheme of the present application is not limited to the support of only four parts, for example, three parts, five parts, etc., and the technical scheme of the present application can be realized.
S4, detecting the densities of the N1 to N4 portions by utilizing a microwave sensor, respectively obtaining the cigarette densities of the corresponding portions to be rho 1 to rho 4, judging whether the difference value between rho 1 or rho 4 and the standard density is in a set range, if so, entering a step S5, and if not, executing a step S6. In this embodiment, specifically, to the fact that several microwave sensors are used to detect different portions of the same cigarette according to actual needs and functions of the microwave sensors, if one microwave sensor can have the function of measuring densities of different portions of the same cigarette at the same time, one microwave sensor may be used, and as far as such microwave sensors are commercially available, one microwave sensor may be configured for each portion to measure densities of corresponding portions of the cigarette, in theory, the two properties are the same, and no obvious difference exists, as long as the separate portions of the cigarette can be detected separately.
And determining the N1 part and the N4 part by the detection of the microwave sensor and the judgment of the controller, wherein one part of the N1 part and the N4 part is detected in the set range with the standard density difference, and judging that the cigarette is unqualified only when the two parts are not in the set range with the standard density difference, and then entering the step S6.
S5, judging whether the densities of the two adjacent parts are smaller than or exceed the set range of the standard density through the cigarettes detected at the N1 end and the N4 end of the cigarettes, wherein the N1 part and the N2 part are adjacent parts, the N2 part and the N3 part are adjacent parts, and the N3 part and the N4 part are adjacent parts.
The step is because the judgment in the previous step is that only the N1 part or the N4 part accords with the standard density range, at this time, if N1 accords with the standard, N4 does not accord with the standard, but because the detection of the end part of the cigarette is included, the N4 part generally accords with the standard, at this time, basically the N1 part has the possibility of not accord with the standard, if the N2 part does not accord with the standard any more, tobacco shreds at the joint of the cigarette and the filter tip are less easy to pinch, the quality of the cigarette is influenced, and the same N2 part and the same N3 part are the same.
S6, judging that the cigarettes to be detected are unqualified, and sending a rejection signal to a rejection system for rejection. This step belongs to the now conventional step for which the applicant does not need to make excessive description, the technique of which will be clear to the person skilled in the art.
The technical scheme of the application further comprises the steps of obtaining a tobacco shred distribution map in a set time period (the set time period can be 10S, 20S, 30S, 60S, 90S, 120S and other time periods) by utilizing the density of the N1 part in the step S4, the density of the N4 part and the standard deviation of the set time between the density of the adjacent part in the step S5 and the standard density, comparing the tobacco shred distribution map with the tobacco shred distribution map of a standard cigarette, and adjusting the regulation parameters of the tobacco feeder.
The present application is not limited to the above embodiments, but is not limited to the above embodiments, and any person skilled in the art will have obvious modifications and modifications equivalent to those of the equivalent embodiments, and can make various changes and modifications without departing from the scope of the present application.
