[0047] The core of this invention is to provide a cigarette weight control method. By comparing the average weight of multiple cigarettes with a preset target value, it determines when the particle filling amount of the cigarette deviates significantly from the ideal value. Furthermore, by adjusting the height of the feeding tray, precise control of cigarette weight is achieved, thus controlling costs while improving the user experience. Another core aspect of this invention is to provide a cigarette weight control device, equipment, and computer-readable storage medium. This device also determines when the particle filling amount of the cigarette deviates significantly from the ideal value by comparing the average weight of multiple cigarettes with a preset target value. Furthermore, by adjusting the height of the feeding tray, precise control of cigarette weight is achieved, thus controlling costs while improving the user experience.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a cigarette weight control method provided by the present invention. The cigarette weight control method includes:

[0050] S101: In response to a weighing trigger command, obtain the average weight of the first preset quantity of cigarettes produced recently;

[0051] Specifically, considering the technical problems mentioned above, and considering that the average weight of multiple cigarettes can reflect the accuracy of the granule filling amount of the cigarette, this embodiment of the invention aims to evaluate the granule filling amount of the cigarette by using the average weight of the newly generated several cigarettes, so as to trigger the subsequent granule filling amount adjustment step. Therefore, in this step, the average weight of the first preset number of newly produced cigarettes can be obtained first in response to the weighing trigger command.

[0052] Among them, cigarettes can refer to granular heated cigarettes.

[0053] Specifically, the weighing trigger command can be generated in various ways, such as by a human through a human-computer interaction device, and this embodiment of the invention does not limit the method.

[0054] The first preset quantity can be set independently, for example, it can be 20, etc., and this embodiment of the invention does not limit it.

[0055] S102: Determine whether the absolute value of the difference between the average weight and the preset target weight is greater than the first preset threshold.

[0056] Specifically, considering that the average weight of cigarettes should ideally be equal to the preset target weight, in this embodiment of the invention, the absolute value of the difference between the average weight and the preset target weight can be calculated, and the absolute value of the difference can be analyzed to determine whether it is large, that is, whether the absolute value of the difference is greater than the first preset threshold. This is used to determine whether the current cigarette weight is qualified, which is also equivalent to determining whether the amount of cigarette particles filled is qualified.

[0057] The first preset threshold can be set independently, such as 5% of the preset target weight, etc., and this embodiment of the invention does not limit it.

[0058] S103: If it is greater than the target weight, the height of the feeding tray is adjusted according to the difference between the average weight and the preset target weight, the current height of the feeding tray, and the correspondence between the height of the feeding tray and the amount of granules fed, so that the average weight of the cigarettes is equal to the preset target weight.

[0059] Specifically, if the value is greater than the target weight, it indicates that the cigarette weight deviates significantly from the preset target weight, meaning the current particle filling amount (i.e., particle injection amount) is unqualified. Therefore, the average cigarette weight can be adjusted to equal the preset target weight, thus ensuring the cigarette weight is qualified. Considering the proportional relationship between the particle injection amount and the height of the feeding tray of the granular heated cigarette forming equipment, in this embodiment of the invention, the height of the feeding tray can be adjusted based on the difference between the average weight and the preset target weight, the current height of the feeding tray, and the correspondence between the height of the feeding tray and the particle injection amount, so that the average weight of the cigarette equals the preset target weight.

[0060] For a better explanation of the embodiments of the present invention, please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a cigarette weight control device provided by the present invention. The cigarette weight control method in the embodiment of the present invention can be applied to the control unit, and the weight adjustment execution unit of S103 can be a particle quantity adjustment device, which can be installed at the feeding tray for filling the paper tube with particles. The height of the feeding tray is controlled by the rotation position of the motor, thereby controlling the particle filling capacity.

[0061] The aforementioned average weight measurement can be performed using an average weight measuring device, which may include a weight detection sensor and a cigarette removal component. The cigarette removal component can move the cigarettes on the production line one by one onto the weight detection sensor by means of "blowing" or "pushing," so that the weight detection sensor can weigh a first preset number of cigarettes and calculate the average weight. The cigarette removal component can quickly complete the collection of individual cigarettes and measure the weight of each group of collected cigarettes. The first preset number can be set by a touch screen. The installation position of the average weight measuring device can be selected according to the actual situation, such as at the transmission drum or the discharge conveyor belt, etc. This embodiment of the invention is not limited here.

[0062] This invention provides a method for controlling cigarette weight. Considering that the average weight of multiple cigarettes can reflect the accuracy of the particle filling amount, this application can respond to a weighing trigger command to obtain the average weight of the first preset number of cigarettes produced recently. Then, it can determine whether the absolute value of the difference between the average weight and the preset target weight is greater than a first preset threshold. If it is greater, it indicates that the current particle filling amount of the cigarette deviates significantly from the ideal value. The height of the feeding tray can then be adjusted to control the average weight of the cigarettes within the preset target weight, achieving precise control of cigarette weight. This not only controls costs but also improves the user experience.

[0063] Based on the above embodiments:

[0064] As a preferred embodiment, the cigarette weight control method further includes:

[0065] Determine whether the weight of the newly produced single cigarette is up to standard;

[0066] If the cigarettes do not meet the standards, they will be rejected.

[0067] Determine whether cigarette production has ended;

[0068] If the process is not completed, proceed to the step of determining whether the weight of the latest produced single cigarette is up to standard.

[0069] Specifically, considering that the above-mentioned batch weighing process cannot remove individual unqualified cigarettes, and that batch weighing is usually cumbersome, the present invention can evaluate the weight of each cigarette produced, that is, determine whether the weight of the newly produced individual cigarette is qualified. If it is not qualified, it can be removed.

[0070] Specifically, Figure 2 The control unit may include a processor, a touch screen, and a rejection valve. The processor executes a control program to implement a cigarette weight control method, the touch screen is used for setting and displaying weight-related parameters, and the rejection valve is used to remove unqualified cigarettes specified by the processor from the production line.

[0071] As a preferred embodiment, after determining whether the weight of the newly produced single cigarette is qualified, the cigarette weight control method further includes:

[0072] If it fails, increment the number of consecutive failures by one and determine whether the number of consecutive failures reaches the second preset threshold.

[0073] If the condition is met, a weighing trigger command will be generated;

[0074] If the result is satisfactory, the number of consecutive unsatisfactory items will be reset to zero.

[0075] Specifically, considering that judging the average weight of batch weighing is cumbersome and usually requires removing the first preset number of cigarettes from the production line before weighing, in order to reasonably determine the frequency of batch weighing and perform batch weighing when necessary, this embodiment of the invention considers assessing whether batch weighing is necessary based on the judgment of the weight of a single cigarette being unqualified. This embodiment of the invention provides one of the triggering conditions, namely, "the number of consecutive unqualified cigarettes reaches a second preset threshold". Considering that in this case, the amount of cigarette particles injected is likely to be problematic, the weight can be adjusted in a timely manner through condition judgment.

[0076] The second preset threshold can be set independently, and this embodiment of the invention does not limit it.

[0077] As a preferred embodiment, after determining whether the weight of the newly produced single cigarette is qualified, the cigarette weight control method further includes:

[0078] Determine whether the proportion of substandard cigarettes in the second preset quantity of cigarettes produced, based on the current time, is greater than the third preset threshold.

[0079] If the value is greater than the given value, a weighing trigger command will be generated.

[0080] Specifically, this embodiment of the invention provides another triggering condition for assessing whether batch weighing is necessary based on the judgment of the weight of a single cigarette failing to meet the standard, namely, "the proportion of substandard cigarettes in the second preset number of cigarettes produced in the last batch is greater than a third preset threshold". Considering that in some cases, even if there are not multiple cigarettes with consecutive weight failures, cigarettes with weight failures still occur relatively frequently, the amount of particles injected into the cigarettes is likely also problematic. Therefore, this embodiment of the invention can determine whether the proportion of substandard cigarettes in the second preset number of cigarettes produced in the last batch, based on the current time, is greater than the third preset threshold. If it is greater, a weighing trigger command can be generated.

[0081] The second preset quantity and the third preset threshold can both be set independently. For example, the second preset quantity can be set to 100, etc. This embodiment of the invention does not limit the specific number of preset quantities.

[0082] As a preferred embodiment, determining whether the weight of the newly produced single cigarette is qualified includes:

[0083] The weight of a single cigarette is determined based on the filling height of the tobacco particles in the newly produced cigarette, the inner diameter of the cigarette paper tube, and the density of the cigarette particles.

[0084] Determine whether the difference between the weight of a single item and the preset target weight is greater than a first preset threshold.

[0085] If the weight is greater than the specified value, the weight of the newly produced single cigarette is deemed unqualified.

[0086] If the weight is not greater than the specified value, the weight of the newly produced single cigarette is deemed acceptable.

[0087] Specifically, in order to weigh a single cigarette without moving the cigarettes on the production line, this embodiment of the invention can determine the weight of the newly produced single cigarette by the filling height of the tobacco particles, the inner diameter of the cigarette paper tube, and the density of the cigarette particles. The core filling height can be measured without moving the cigarette. For example, the filling height of the tobacco particles of a single cigarette can be obtained by an image acquisition device. The image acquisition device can include a parallel light source, a detection camera, and a signal processing module. The filled cigarette particles are illuminated by the parallel light source, the detection camera captures the projected image of the cigarette, and the signal processing module performs image preprocessing.

[0088] The detection camera can be of various types, such as a CCD (Charge Coupled Device) detection camera, etc., and this embodiment of the invention does not limit it.

[0089] As a preferred embodiment, after adjusting the height of the feeding tray based on the difference between the average weight and the preset target weight, the current height of the feeding tray, and the correspondence between the height of the feeding tray and the amount of granules fed, the cigarette weight control method further includes:

[0090] Generate weighing trigger command.

[0091] Specifically, considering that after a single adjustment, the absolute value of the difference between the actual average cigarette weight and the preset target weight is still not less than the first preset threshold, in this embodiment of the invention, after each adjustment of the height of the feeding tray, a weighing trigger command can be generated, that is, the average weight can be evaluated again until the average weight is qualified, thereby ensuring the effectiveness of the weight adjustment.

[0092] As a preferred embodiment, adjusting the height of the feed tray based on the difference between the average weight and the preset target weight, the current height of the feed tray, and the correspondence between the feed tray height and the particle filling amount includes:

[0093] The current particle filling amount is determined based on the current height of the feed tray and the corresponding relationship between the feed tray height and the particle filling amount.

[0094] The target particle injection amount is determined based on the current particle injection amount and the difference between the average weight and the preset target weight.

[0095] The target height of the feed tray is determined based on the target particle filling volume and its corresponding relationship.

[0096] The height of the feed tray is controlled to the target height so that the target amount of granules can be injected into each cigarette.

[0097] Specifically, considering that the difference between the average weight and the preset target weight can reflect the deviation between the current amount of cigarette particles fed into the cigarette and the ideal amount, the ideal amount can be obtained by combining the "difference between the average weight and the preset target weight" with the "current amount of cigarette particles fed into the cigarette". Therefore, in this embodiment of the invention, the current amount of particles fed into the cigarette can be determined first based on the current height of the feeding tray and the correspondence between the height of the feeding tray and the amount of particles fed into the cigarette. Then, the target amount of particles fed into the cigarette can be determined based on the current amount of particles fed into the cigarette and the difference between the average weight and the preset target weight. Based on the target amount of particles fed into the cigarette and the corresponding relationship, the target height of the feeding tray can be determined. Finally, the height of the feeding tray can be controlled to be the target height.

[0098] The relationship between the height of the feed tray and the amount of granules poured in can be set independently, and this embodiment of the invention does not impose any limitations on it.

[0099] Specifically, when controlling the height of the feed tray, the height of the feed tray can be controlled by controlling the rotation position of the motor, thereby improving the control accuracy.

[0101] The acquisition module 31 is used to acquire the average weight of the first preset number of cigarettes produced in response to the weighing trigger command.

[0102] The judgment module 32 is used to determine whether the absolute value of the difference between the average weight and the preset target weight is greater than the first preset threshold. If it is greater, the action module is triggered.

[0103] Action module 33 is used to adjust the height of the feeding tray based on the difference between the average weight and the preset target weight, the current height of the feeding tray, and the correspondence between the height of the feeding tray and the amount of granules fed in, so that the average weight of the cigarettes is equal to the preset target weight.
