Description

Technical Field

[0001] This application belongs to the field of cigarette processing technology, and specifically relates to a method and system for controlling the breaking of cigarette packs based on a cigarette rolling machine. Background Technology

[0002] As a key piece of equipment in the tobacco manufacturing industry, cigarette rolling machines are mainly used to automatically roll tobacco into tobacco strips and further process them into finished cigarettes. This process involves multiple steps, such as tobacco feeding, tobacco forming, tobacco strip rolling, cigarette cutting, filter tip installation, cigarette inspection, and tobacco packaging.

[0003] In the cigarette rolling process mentioned above, the cigarette rolling machine can wrap the tobacco strips with cigarette paper to form a preliminary cigarette strip. However, the current ZJ17 cigarette rolling machine generates a large number of waste long cigarette strips when the equipment starts and stops. These long cigarette strips cannot be directly recycled and need to be manually broken and recycled by operators using knives or conventional splitting equipment to separate the tobacco and rolling paper. This method is not only inefficient but also difficult to operate, which affects the overall tobacco recycling experience. Summary of the Invention

[0004] This application addresses the issue of long, waste cigarette sticks generated during the start-up and shutdown of cigarette rolling machines. These long cigarette sticks cannot be directly recycled and require manual cutting and recycling by operators using knives to separate the tobacco and rolling paper. This method is not only inefficient but also difficult, thus affecting the overall tobacco recycling experience. The application proposes a cigarette stick cutting and breaking control method and system based on cigarette rolling machines, the technical solution of which is as follows:

[0005] In a first aspect, embodiments of this application provide a method for controlling the breaking of cigarette sticks based on a cigarette rolling machine. The method is applied to a cigarette stick breaking device, which includes a cigarette breaking device, a first rotating roller, a second rotating roller, a first motor for controlling the first rotating roller, a second motor for controlling the second rotating roller, a cigarette stick guide seat, a protective cover, and a relay. The first motor, the second motor, and the cigarette stick guide seat are all mounted on the cigarette breaking device. The first rotating roller is positioned above the first motor, and the second rotating roller is positioned above the second motor. The smoke outlet of the cigarette stick guide seat is located between the first and second rotating rollers. The protective cover is positioned above the first and second rotating rollers. The normally open contact of the first motor and the relay forms a circuit, and the normally open contact of the second motor and the relay also forms a circuit. The method includes:

[0006] When at least two cigarette sticks to be processed are identified in the cigarette stick guide seat, the arrangement of all cigarette sticks to be processed is determined;

[0007] The motor control parameters are obtained based on the arrangement of all the cigarette sticks to be processed, and when the protective cover is detected to be in the closed state, a high-level signal is output to the relay to make the normally open contact of the relay switch to the conducting state.

[0008] Based on the motor control parameters, the first motor and the second motor are controlled respectively so that the first rotating roller and the second rotating roller convey all the tobacco strips to be processed to the tobacco breaking device, and the tobacco breaking device breaks all the tobacco strips to be processed.

[0009] The paper separating all the tobacco sticks to be processed by the tobacco breaking device is identified and processed, and when tobacco shreds are detected on the paper, the tobacco shreds on the paper are removed.

[0010] In one alternative to the first aspect, the arrangement of all the cigarette sticks to be processed is determined, including:

[0011] Obtain an image of all cigarette sticks to be processed, and identify the center point coordinates of each cigarette stick to be processed in the image;

[0012] Divide the coordinates of all center points into at least two sets of coordinate intervals, and use the number of sets of all coordinate intervals as the number of rows of cigarette packs.

[0013] The number of cigarette sticks in each row is counted based on the x-coordinates of all center points. Based on the number of rows of cigarette sticks and the number of cigarette sticks in each row, the arrangement of all cigarette sticks to be processed is obtained.

[0014] In another alternative to the first aspect, the motor control parameters are obtained based on the arrangement of all the cigarette strips to be processed, including:

[0015] When the number of cigarette sticks corresponding to any two rows is the same, the number of cigarette sticks is taken as the number of cigarette stick columns, and the motor speed corresponding to the number of cigarette stick rows and the number of cigarette stick columns is retrieved from the preset database. The preset database includes at least two sets of permutations and combinations and the motor speed corresponding to each set of permutations and combinations. Each set of permutations and combinations includes the number of cigarette stick rows and the number of cigarette stick columns.

[0016] The preset first direction and motor speed are used as the motor control parameters corresponding to the first motor, and the preset second direction and motor speed are used as the motor control parameters corresponding to the second motor; wherein the preset first direction and the preset second direction are opposite directions.

[0017] In another alternative to the first aspect, the motor control parameters are obtained based on the arrangement of all the cigarette strips to be processed, and further include:

[0018] When the number of cigarette sticks corresponding to any two rows is inconsistent, the difference between the number of cigarette sticks corresponding to any two adjacent rows is calculated.

[0019] When any difference is detected to be within the preset difference range, the row number corresponding to the minimum number of cigarette sticks is counted.

[0020] When the row number corresponding to the minimum number of cigarette sticks is detected to be within the preset number range, the minimum number of cigarette sticks is taken as the column number of cigarette sticks, and the motor speed corresponding to the number of cigarette stick rows and columns is retrieved from the preset database;

[0021] The preset first direction and motor speed are used as the motor control parameters corresponding to the first motor, and the preset second direction and motor speed are used as the motor control parameters corresponding to the second motor.

[0022] In another alternative to the first aspect, the motor control parameters are obtained based on the arrangement of all the cigarette strips to be processed, and further include:

[0023] When the number of cigarette sticks corresponding to any two rows is inconsistent, the difference between the number of cigarette sticks corresponding to any two adjacent rows is calculated.

[0024] When any difference is detected that is not within the preset difference range, the maximum difference between the number of cigarette sticks corresponding to any two adjacent rows is determined.

[0025] The maximum difference and the preset ratio coefficient are calculated as a ratio, and the ratio result is summed with the minimum number of cigarette sticks to obtain the sum result;

[0026] The summation result is used as the number of columns of the cigarette pack, and the motor speed corresponding to the number of rows and columns of the cigarette pack is retrieved from the preset database.

[0027] The preset first direction and motor speed are used as the motor control parameters corresponding to the first motor, and the preset second direction and motor speed are used as the motor control parameters corresponding to the second motor.

[0028] In another alternative to the first aspect, the paper strips separated from all the tobacco sticks to be processed by the tobacco breaking device are identified and processed, including:

[0029] The paper roll image containing the paper separated from all the tobacco sticks to be processed by the tobacco breaking device is obtained, and the paper roll image and the tobacco shred images corresponding to all the tobacco sticks to be processed are input into a preset deep learning model to obtain the tobacco shred presence probability; wherein, the preset deep learning model is trained by at least two paper roll sample images, the standard tobacco shred image corresponding to each paper roll sample image, and the standard presence probability.

[0030] When the probability of tobacco shreds being present exceeds a preset probability threshold, it is determined that tobacco shreds are present on the rolling paper.

[0031] If the probability of tobacco shreds being present does not exceed a preset probability threshold, it is determined that there are no tobacco shreds on the roll.

[0032] In another alternative of the first aspect, the cigarette bar breaking device further includes a limit switch, which is set on the circuit formed by the normally open contacts of the first motor and the relay, and the limit switch is also set on the circuit formed by the normally open contacts of the second motor and the relay.

[0033] Secondly, embodiments of this application provide a cigarette bar breaking control system based on a cigarette rolling machine. The system is applied to a cigarette bar breaking device, which includes a cigarette breaking device, a first rotating roller, a second rotating roller, a first motor for controlling the first rotating roller, a second motor for controlling the second rotating roller, a cigarette bar guide seat, a protective cover, and a relay. The first motor, the second motor, and the cigarette bar guide seat are all mounted on the cigarette breaking device. The first rotating roller is positioned above the first motor, and the second rotating roller is positioned above the second motor. The smoke outlet of the cigarette bar guide seat is located between the first rotating roller and the second rotating roller. The protective cover is positioned above the first rotating roller and the second rotating roller. The normally open contact of the first motor and the relay forms a circuit, and the normally open contact of the second motor and the relay also forms a circuit. The system includes:

[0053] Please see Figure 1 , Figure 1 The diagram shows an overall flowchart of a cigarette bar breaking control method based on a cigarette rolling machine, as provided in an embodiment of this application.

[0054] like Figure 1 As shown, the cigarette bar breaking control method based on a cigarette rolling machine may include at least the following steps:

[0055] Step 102: When at least two cigarette sticks to be processed are identified in the cigarette stick guide seat, determine the arrangement of all cigarette sticks to be processed.

[0056] In this embodiment, the tobacco strip breaking control method based on a cigarette rolling machine can be applied to, but is not limited to, a control terminal. This control terminal establishes a connection with a tobacco strip breaking device to control the device to break up the waste long tobacco strips generated during the start-up and shutdown of the cigarette rolling machine. This effectively and quickly separates the tobacco from the rolling paper, avoiding the inefficiencies and operational difficulties caused by manual labor. The tobacco strip breaking device can include at least a tobacco breaking device, a first rotating roller, a second rotating roller, a first motor for controlling the first rotating roller, a second motor for controlling the second rotating roller, a tobacco strip guide seat, a protective cover, and a relay. The tobacco breaking device receives the waste long tobacco strips generated by the cigarette rolling machine through the feed inlet and uses a built-in control program to control the cutting mechanism to automatically break up the waste long tobacco strips (i.e., cut the rolling paper surface of the waste long tobacco strips). It also uses a built-in control program to control the separation mechanism to automatically separate the tobacco from the rolling paper, and outputs the separated tobacco and rolling paper through the discharge outlet. It should be noted that the tobacco breaking device (including the cutting mechanism and the separation mechanism mentioned above) mentioned in the embodiments of this application can be a conventional device used by those skilled in the art to break up waste long tobacco sticks. For example, but not limited to, the tobacco breaking machine, tobacco crusher or tobacco grinder and other equipment and their working principles can be referred to in the art. It is mainly used to break up waste long tobacco sticks and separate tobacco and cigarette paper. It will not be described in detail here.

[0057] The first and second motors (both can be understood as DC brushless geared motors) can be mounted on the surface of the smoke-breaking device, for example, but not limited to, symmetrically arranged on both sides of the feed inlet of the smoke-breaking device. Based on the motor control parameters output by the control terminal, they respectively control the rotation of the first rotating roller above the first motor and the second rotating roller above the second motor, thereby allowing the waste smoke sticks to be conveyed through the gap between the first and second rotating rollers to the feed inlet of the smoke-breaking device. Here, the first and second motors can also be equipped with their own respective motor controllers, which receive the motor control parameters output by the control terminal and control the first and second motors accordingly, but are not limited to this.

[0058] The cigarette bar guide seat can also be installed on the surface of the cigarette breaking device. The outlet of the cigarette bar guide seat is located between the first rotating roller and the second rotating roller. The inlet of the cigarette bar guide seat can be used by a worker to place the waste long cigarette bars produced by the cigarette rolling machine, or by other automatic control equipment to place the waste long cigarette bars produced by the cigarette rolling machine. The waste long cigarette bars can be automatically conveyed from the inlet to the outlet through a built-in conveying mechanism, but is not limited to this. Of course, the cigarette bar guide seat can also convey the waste long cigarette bars from the inlet to the outlet according to the control commands output by the control terminal, and is not limited to this.

[0059] See also: Figure 2 The diagram shown illustrates the effect of a cigarette bar breaking device provided in an embodiment of this application. Figure 2 As shown, the cigarette bar breaking device may include a cigarette bar breaking device, two motors symmetrically arranged on both sides of the feed inlet of the cigarette bar breaking device, two rotating rollers arranged on the motors, and a cigarette bar guide seat arranged on the cigarette bar breaking device with the cigarette outlet located between the two rotating rollers. The waste long cigarette bars generated when the cigarette machine starts and stops can pass through the cigarette bar guide seat and the gap between the two rotating rollers in sequence to reach the feed inlet of the cigarette bar breaking device, and the cigarette bar breaking device automatically realizes the breaking and separation of the waste long cigarette bars.

[0060] The protective cover can also be installed on the surface of the smoke-breaking device, and its inner cavity can be used to enclose the first and second rotating rollers. This means it is positioned above the first and second rotating rollers to protect them and effectively prevent safety hazards to workers. The protective cover can have an open and a closed state (the state can be manually controlled or controlled by a control terminal). When the protective cover is open, the inner cavity formed by the cover cannot enclose the first and second rotating rollers, indicating that workers need to inspect and maintain them, and the smoke-breaking process cannot be performed. When the protective cover is closed, the inner cavity formed by the cover can enclose the first and second rotating rollers, indicating that there is no immediate plan to inspect and maintain them, and the smoke-breaking process can proceed normally.

[0061] One end of the relay can be connected to the positive output terminal of the control terminal to receive the level signal output by the control terminal. The other end can be connected, but is not limited to, to the ground terminal or the negative input terminal of the control terminal. When the control terminal outputs a high-level signal to the relay, the relay can be energized, thereby causing the normally open contact of the relay to change from the open state to the closed state. Here, the normally open contact of the relay can form a circuit with the first motor and the power supply, and also with the second motor and the power supply. When the normally open contact of the relay is in the open state, the first motor and the second motor cannot be in the working state, that is, the waste long cigarette bar cannot be conveyed to the feed inlet of the smoke breaking device through the first rotating roller and the second rotating roller. When the normally open contact of the relay changes from the open state to the closed state, the first motor and the second motor can be in the working state, that is, the waste long cigarette bar can be conveyed to the feed inlet of the smoke breaking device through the first rotating roller and the second rotating roller.

[0062] Of course, the cigarette bar breaking device in this embodiment may also include a limit switch. This limit switch can be configured on the circuit formed by the normally open contact of the relay, the first motor, and the power supply, and may also be configured on the circuit formed by the normally open contact of the relay, the second motor, and the power supply. Here, the limit switch may, but is not limited to, be controlled by a worker. For example, when a worker needs to use the cigarette bar breaking device to break up waste cigarette bars, they can press a button corresponding to the limit switch at a point on the touchscreen or the surface of the breaking device to change the limit switch from an open state to a closed state. This, combined with the normally open contact of the relay, allows the first and second motors to operate.

[0063] See also: Figure 3 The diagram shown illustrates the effect of another tobacco strip breaking device provided in this application embodiment. Figure 3 As shown, the first motor (M1 in the figure) of the cigarette bar breaking device can be connected to the corresponding motor controller (A1 in the figure), and the second motor (M2 in the figure) can be connected to the corresponding motor controller (A2 in the figure). The negative terminal of the power supply of the motor controller (A1 in the figure) can be connected to the negative terminal of the 24-volt power supply, and the positive terminal of the power supply of the motor controller (A1 in the figure) can be connected to the positive terminal of the 24-volt power supply through the limit switch (S1 in the figure) and the normally open contact of the relay (S2 in the figure). The negative terminal of the power supply of the motor controller (A2 in the figure) can be connected to the negative terminal of the 24-volt power supply, and the positive terminal of the power supply of the motor controller (A2 in the figure) can be connected to the positive terminal of the 24-volt power supply through the limit switch (S1 in the figure) and the normally open contact of the relay (S2 in the figure).

[0064] It is also understandable that the control terminal determines the motor control parameters based on the arrangement of all the tobacco sticks to be processed in the tobacco stick guide seat, so that the corresponding rotating rollers can stably and efficiently transport all the tobacco sticks to be processed to the tobacco breaking device, and the tobacco breaking device can break all the tobacco sticks to be processed, thereby realizing the automation of tobacco stick breaking; and can also identify the separated paper to further improve the separation accuracy between tobacco and paper, thereby effectively improving the overall breaking efficiency.

[0065] Specifically, when breaking up the waste long cigarette sticks generated when the cigarette machine starts and stops, the control terminal can, but is not limited to, acquire images of the cigarette sticks in the cigarette stick guide seat through an industrial camera, and determine whether there are at least two cigarette sticks to be processed in the current cigarette stick guide seat by performing cigarette stick recognition processing on the cigarette stick image, that is, whether it is necessary to break up the waste long cigarette sticks.

[0066] It is understandable that when the presence of at least two unprocessed cigarette sticks within the cigarette stick guide seat is identified through the cigarette stick image, it indicates that the waste long cigarette sticks need to be broken open. Furthermore, the arrangement of all unprocessed cigarette sticks within the cigarette stick guide seat can be determined based on, but is not limited to, the cigarette stick image. Here, the arrangement of all unprocessed cigarette sticks can be understood as the number of rows of cigarette sticks divided into which all unprocessed cigarette sticks are divided, and the number of cigarette sticks corresponding to each row. In this embodiment, the arrangement of all unprocessed cigarette sticks is not limited to a regular arrangement (e.g., m*n) or an irregular arrangement (e.g., two rows, with m and n cigarette sticks corresponding to each row).

[0067] As an optional embodiment of this application, determining the arrangement of all cigarette sticks to be processed includes:

[0068] Obtain an image of all cigarette sticks to be processed, and identify the center point coordinates of each cigarette stick to be processed in the image;

[0069] Divide the coordinates of all center points into at least two sets of coordinate intervals, and use the number of sets of all coordinate intervals as the number of rows of cigarette packs.

[0070] The number of cigarette sticks in each row is counted based on the x-coordinates of all center points. Based on the number of rows of cigarette sticks and the number of cigarette sticks in each row, the arrangement of all cigarette sticks to be processed is obtained.

[0071] Specifically, when determining the arrangement of all the cigarette sticks to be processed, the control terminal can, but is not limited to, acquiring an image of all the cigarette sticks to be processed using the aforementioned industrial camera, and identifying the contour features corresponding to each cigarette stick from the image. It is understood that the industrial camera used to acquire the cigarette stick image can, but is not limited to, be positioned in the direction of the cigarette stick conveying pipeline of the cigarette stick guide seat, and the industrial camera can be oriented towards the inside of the cigarette stick guide seat to more accurately capture an image containing all the cigarette sticks to be processed.

[0072] Next, after identifying the contour features corresponding to each cigarette stick to be processed, the control terminal can also, but is not limited to, establish a Cartesian coordinate system on the plane where the cigarette stick image is located, and determine the corresponding center point coordinates in the Cartesian coordinate system according to the contour features corresponding to each cigarette stick to be processed. The center point coordinates of each cigarette stick to be processed are the center point coordinates corresponding to the corresponding contour features.

[0073] Next, after determining the center point coordinates of each cigarette stick to be processed, the control terminal can further divide the data into intervals based on the ordinates of all center point coordinates. This allows for the grouping of similar or identical ordinates into the same coordinate interval. Specifically, within any given coordinate interval, the difference between any two ordinates must be less than a preset threshold. The number of intervals corresponding to all coordinate intervals can then be used as the number of rows for all cigarette sticks to be processed. It is understandable that after determining all coordinate intervals, the control terminal can also sort these intervals in ascending order. For example, but not limited to, rows with coordinate interval [1-2] as the first row, rows with coordinate interval [2-3] as the second row, and rows with coordinate interval [3-4] as the third row.

[0074] Next, the control terminal can count the number of corresponding horizontal coordinates based on all vertical coordinates in each coordinate interval, and use the number of horizontal coordinates as the number of cigarette sticks in that coordinate interval. The number of cigarette stick rows mentioned above, as well as the number of cigarette sticks counted in each row, are used as the arrangement of all cigarette sticks to be processed.

[0075] Step 104: Obtain motor control parameters based on the arrangement of all the cigarette sticks to be processed, and when the protective cover is detected to be in the closed state, output a high-level signal to the relay so that the normally open contact of the relay is switched to the conducting state.

[0076] Specifically, after obtaining the arrangement of all the cigarette sticks to be processed, the control terminal can obtain the motor control parameters of the first and second motors based on the arrangement. For example, but not limited to, when the number of cigarette sticks corresponding to any two rows in the arrangement is the same, it indicates that the arrangement of all the cigarette sticks to be processed conforms to an m*n array. Therefore, any number of cigarette sticks can be directly used as the column number, and the motor speed corresponding to the column number and row number can be retrieved from a preset database. Here, the preset data may include at least two manually set arrangement combinations, and the standard motor speed corresponding to each arrangement combination after manual testing. Each arrangement combination may specifically include the number of cigarette stick columns and the number of cigarette stick rows.

[0077] Furthermore, after retrieving the motor speed from the preset database, to ensure that the first and second rotating rollers can properly transport the tobacco strips to be processed to the feed inlet of the tobacco breaking device, a preset first direction and the motor speed can be used as the motor control parameters corresponding to the first motor, and a preset second direction and the motor speed can be used as the motor control parameters corresponding to the second motor. The preset first and second directions are opposite, meaning that the combined rotation of the first and second rotating rollers is used to transport the tobacco strips to be processed to the feed inlet of the tobacco breaking device. Here, the motor control parameters may also include parameters such as control time and control frequency, and the control time and control frequency corresponding to the first motor and the control time and control frequency corresponding to the second motor can be consistent, and are not limited to these.

[0078] Furthermore, after obtaining the motor control parameters corresponding to each motor, the control terminal can also detect and process the status of the protective cover to avoid safety hazards caused by the first and second rotating rollers. Here, when the status of the protective cover is manually operated, the control terminal can, but is not limited to, using the aforementioned industrial camera to quickly identify whether the protective cover is in an open or closed state; when the status of the protective cover is controlled by an automatic program, the control terminal can, but is not limited to, detect whether it has received user input operations or commands, so as to identify whether the protective cover is in an open or closed state through such operations or commands.

[0079] Furthermore, when the protective cover is confirmed to be closed, it indicates that the cigarette bar breaking process can proceed normally. The control terminal then outputs a high-level signal to the relay circuit, causing the normally open contact of the relay to switch from an open to a closed state after the relay is energized. This connects the first motor to the power supply circuit, ensuring the first motor is in normal working condition, and also connects the second motor to the power supply circuit, ensuring the second motor is also in normal working condition. Conversely, when the protective cover is confirmed to be open, it indicates that the cigarette bar breaking process cannot proceed. The control terminal can then promptly send a check signal to personnel to determine if there are any abnormalities in the protective cover, thus preventing further losses.

[0080] Understandably, when the control terminal is not certain that the protective cover is closed, it can continuously output a low-level signal to the circuit containing the relay, that is, the normally open contact of the relay remains open, in order to avoid additional power cost losses.

[0081] As another optional embodiment of this application, obtaining the motor control parameters based on the arrangement of all the cigarette strips to be processed further includes:

[0082] When the number of cigarette sticks corresponding to any two rows is inconsistent, the difference between the number of cigarette sticks corresponding to any two adjacent rows is calculated.

[0083] When any difference is detected to be within the preset difference range, the row number corresponding to the minimum number of cigarette sticks is counted.

[0084] When the row number corresponding to the minimum number of cigarette sticks is detected to be within the preset number range, the minimum number of cigarette sticks is taken as the column number of cigarette sticks, and the motor speed corresponding to the number of cigarette stick rows and columns is retrieved from the preset database;

[0085] The preset first direction and motor speed are used as the motor control parameters corresponding to the first motor, and the preset second direction and motor speed are used as the motor control parameters corresponding to the second motor.

[0086] Specifically, when determining the motor control parameters corresponding to each motor based on the arrangement, if the control terminal detects that the number of cigarette sticks corresponding to any two rows in the arrangement is inconsistent, it indicates that the arrangement of all cigarette sticks to be processed does not conform to the m*n array. Then, the difference between the number of cigarette sticks corresponding to any two adjacent rows can be calculated. This difference can be used to determine whether there is a large difference in the number of cigarette sticks between any two adjacent rows. When any difference is detected to be within the preset difference range, it indicates that the difference in the number of cigarette sticks between any two adjacent rows is small. Then, the number of rows corresponding to the smallest number of cigarette sticks can be counted.

[0087] Understandably, when the row number corresponding to the smallest number of cigarette sticks is detected to be within a preset range, it indicates that the difference in the number of cigarette sticks in each row among all the cigarette sticks to be processed is not significant. Therefore, the smallest number of cigarette sticks can be used as the column number, and the motor speed corresponding to the column number and row number can be retrieved from a preset database. Here, when the row number corresponding to the smallest number of cigarette sticks is detected to be outside the preset range, the row number corresponding to the second smallest number of cigarette sticks can be counted to determine whether the second smallest number of cigarette sticks is within the preset range. When the second smallest number of cigarette sticks is detected to be within the preset range, the second smallest number of cigarette sticks can be used as the column number, but this is not a limitation.

[0088] Next, after querying the motor speed in the preset database, in order to ensure that the first rotating roller and the second rotating roller can transport the tobacco strips to be processed to the feed inlet of the tobacco breaking device normally, the preset first direction and the motor speed can be used as the motor control parameters corresponding to the first motor, and the preset second direction and the motor speed can be used as the motor control parameters corresponding to the second motor. The preset first direction and the preset second direction are opposite directions, that is, the combined rotation of the first rotating roller and the second rotating roller is used to transport the tobacco strips to be processed to the feed inlet of the tobacco breaking device.

[0089] As another optional embodiment of this application, obtaining the motor control parameters based on the arrangement of all the cigarette strips to be processed further includes:

[0090] When the number of cigarette sticks corresponding to any two rows is inconsistent, the difference between the number of cigarette sticks corresponding to any two adjacent rows is calculated.

[0091] When any difference is detected that is not within the preset difference range, the maximum difference between the number of cigarette sticks corresponding to any two adjacent rows is determined.

[0092] The maximum difference and the preset ratio coefficient are calculated as a ratio, and the ratio result is summed with the minimum number of cigarette sticks to obtain the sum result;

[0093] The summation result is used as the number of columns of the cigarette pack, and the motor speed corresponding to the number of rows and columns of the cigarette pack is retrieved from the preset database.

[0094] The preset first direction and motor speed are used as the motor control parameters corresponding to the first motor, and the preset second direction and motor speed are used as the motor control parameters corresponding to the second motor.

[0095] Specifically, when determining the motor control parameters corresponding to each motor based on the arrangement, if the control terminal detects that the number of cigarette sticks corresponding to any two rows in the arrangement is inconsistent, it indicates that the arrangement of all cigarette sticks to be processed does not conform to the m*n array. Then, the difference between the number of cigarette sticks corresponding to any two adjacent rows can be calculated. This difference can be used to determine whether there is a large difference in the number of cigarette sticks between any two adjacent rows. When any difference is detected to be outside the preset difference range, it indicates that the difference in the number of cigarette sticks between any two adjacent rows may be large. Then, the maximum difference between the number of cigarette sticks corresponding to any two adjacent rows can be determined.

[0096] Next, after obtaining the maximum difference, to ensure the stability of each row of cigarette sticks during transportation (i.e., to prevent a row of cigarette sticks from slipping due to the rotation speed of the rotating rollers), the control terminal can calculate the ratio of the maximum difference to a preset proportional coefficient. This preset proportional coefficient can be, but is not limited to, 2. The ratio result is then summed with the minimum number of cigarette sticks to obtain the sum. It is understood that the result calculated in the above manner can comprehensively consider both the maximum and minimum number of cigarette sticks in each row, and can also ensure that any row of cigarette sticks does not fall off during transportation through the gap between the first and second rotating rollers, but is not limited to this.

[0097] It should also be noted that, in this embodiment of the application, the distance between the first rotating roller and the second rotating roller can be further determined based on the arrangement of all the cigarette sticks to be processed, so as to further ensure the stability of each row of cigarette sticks during transportation.

[0098] Step 106: Control the first motor and the second motor respectively based on the motor control parameters so that the first rotating roller and the second rotating roller convey all the tobacco strips to be processed to the tobacco breaking device, and the tobacco breaking device breaks all the tobacco strips to be processed.

[0099] Specifically, after determining the motor control parameters corresponding to the first motor and the second motor, the control terminal can send the motor control parameters to the corresponding motors, so that the first motor controls the first rotating roller to rotate according to the corresponding motor control parameters, and the second motor controls the second rotating roller to rotate according to the corresponding motor control parameters. The combined rotation of the first and second rotating rollers can transport all the tobacco strips to be processed to the tobacco breaking device, and the tobacco breaking device can then perform the breaking and separation of all the tobacco strips to be processed.

[0100] Step 108: Identify and process the paper separated from all the tobacco sticks to be processed by the tobacco breaking device, and remove the tobacco shreds when tobacco shreds are detected on the paper.

[0101] Specifically, after the tobacco breaking device completes the breaking and separation of all the tobacco sticks to be processed, in order to ensure the separation effect between the tobacco and the cigarette paper, the control terminal can, but is not limited to, acquire an image of the cigarette paper containing all the tobacco sticks to be processed separated by the tobacco breaking device through an industrial camera, so as to determine whether there are residual tobacco in the separated cigarette paper by recognizing the image of the cigarette paper.

[0102] Furthermore, after obtaining the image of the rolled paper containing the paper, the control terminal can input the rolled paper image and the tobacco shred images corresponding to all the tobacco sticks to be processed into a preset deep learning model, so as to more accurately determine whether there are residual tobacco shreds in the separated rolled paper through neural network prediction. It is understood that the tobacco shred images corresponding to all the tobacco sticks to be processed can be, but are not limited to, being obtained by taking pictures of the tobacco shreds separated by the tobacco breaking device by an industrial camera. The preset deep learning model can be trained by at least two manually set sample images of rolled paper, the standard tobacco shred image corresponding to each sample image of rolled paper, and manually set standard existence probabilities. Moreover, the preset deep learning model can predict the probability value used to characterize whether there are residual tobacco shreds, that is, any value in the range of 0-1.

[0103] Furthermore, when the probability of tobacco shreds output by the preset deep learning model exceeds the preset probability threshold, it indicates that there are still residual tobacco shreds in the separated rolling paper, thus confirming the presence of tobacco shreds on the rolling paper. It can also issue a removal signal to the staff, but is not limited to, to promptly remind the staff to remove the tobacco shreds from the rolling paper. When the probability of tobacco shreds output by the preset deep learning model does not exceed the preset probability threshold, it indicates that there are no residual tobacco shreds in the separated rolling paper, thus confirming the absence of tobacco shreds on the rolling paper.
