Description

Technical Field

[0001] This invention relates to the field of cigarette equipment operation control technology, and in particular to a control method for an adhesive application mechanism. Background Technology

[0002] In the production process of new heated tobacco cigarettes, the high moisture content of the atomized tobacco causes it to shrink upon heating, resulting in irregular gaps between the tobacco bundle and the aluminum foil, thus reducing the relative friction between them. Simultaneously, the high barrier properties of the aluminum foil weaken the adhesion between the tobacco bundle and the foil, further reducing the friction. When the cigarette cartridge is rotated and drawn, if the friction between the tobacco bundle and the aluminum foil is too low, it may cause the tobacco bundle to slip and detach from the foil, resulting in a quality defect in the cigarette.

[0003] At present, the cigarette rolling equipment for the new tobacco smoking section is generally the ZJ118 cigarette rolling machine, but the original equipment does not have a glue application mechanism and corresponding control method. Summary of the Invention

If there are defective segments, mark the defective segments in the glue application image and simultaneously issue rejection information. Based on the running information of the cigarette paper, the running position of the defective segment is determined. When the defective segment reaches the rejection position, the defective segment is rejected. The running information includes the running speed of the cigarette paper and the segment length when the cigarette paper is cut after being glued.

[0006] Preferably, before entering the gluing mode, the process further includes: Predefined standard rubber storage area; Obtain the glue storage quantity; Determine whether the amount of adhesive stored is within the standard adhesive storage range: If the amount of glue stored is within the standard glue storage range, then the glue application mode is entered; If the amount of glue stored is not less than the standard glue storage range, a glue discharge signal is issued; If the amount of glue stored is not greater than the standard glue storage range, a glue replenishment signal is issued.

[0007] Preferably, entering the gluing mode specifically includes: Step S11: Predefine a standard pressure range, which includes a maximum pressure value and a minimum pressure value; Step S12: Drive the cigarette paper to run and open the adhesive application part; Step S13: Obtain the pressure value, wherein the pressure value is the pressure inside the connecting pipe between the adhesive application component and the adhesive supply component; Step S14: Determine whether the pressure value is within the standard pressure range. If the pressure value is within the standard pressure range, return to step S13.

Obtain the current type of cigarette paper, and retrieve the corresponding operating information and the corresponding adhesive parameters.

[0009] Preferably, step S14 specifically includes: Determine whether the pressure value is less than the maximum pressure value: If the pressure value is not less than the maximum pressure value, then enter high-pressure mode; If the pressure value is less than the maximum pressure value, then determine whether the pressure value is greater than the minimum pressure value: If the pressure value is not greater than the minimum pressure value, then enter low-pressure mode; If the pressure value is greater than the minimum pressure value, then maintain the status quo and return to step S13; The high-pressure mode includes shutting down all devices and outputting a high-pressure alarm; the low-pressure mode includes shutting down all devices and outputting a low-pressure alarm.

[0010] Preferably, before step S12, a predefined glue filling value is also included.

[0011] Preferably, after step S12, the method further includes: Step S15: Obtain the current amount of glue stored; Step S16: Determine whether the current glue storage amount is greater than the glue replenishment value: If the current glue storage amount is greater than the glue replenishment value, then maintain the status quo and return to step S15; If the current glue storage level is not greater than the glue replenishment value, then enter maintenance mode; The maintenance mode includes shutting down all devices and outputting a low margin signal.

[0012] Preferably, determining whether there are defective segments in the adhesive application image specifically includes: Based on the standard adhesive application image, determine whether the defective segment exists in the adhesive application image: If the defective segment exists, mark the defective segment in the glue application image and simultaneously issue a rejection message; If no non-compliant segment exists, then enter the splitting mode.

[0013] Preferably, determining the running position of the defective segment based on the cigarette paper's running information, and removing the defective segment when it reaches the rejection position, specifically includes: The segment length is predefined, and the starting point of the initial gluing is marked as the cutting start point. The cutting start point is used as the initial cutting position, and every segment length is marked as a cutting point. Determine the starting position and the ending position, wherein the starting position is the running position of the beginning end of the non-conforming segment, and the ending position is the running position of the ending end of the non-conforming segment; Obtain the cutting point closest to the starting position; When the cutting point reaches the rejection position, the cigarette paper corresponding to the cutting point and the end position is rejected.

[0014] Preferably, after removing the cigarette paper corresponding to the cutting point and the end position, the method further includes marking the end position as the cutting start point, and cutting the cigarette paper based on the running speed and the segment length.

[0015] The beneficial effects of this invention are as follows: This invention can detect cigarette segments with substandard adhesive application, and after marking the substandard segments, it feeds back the corresponding information to the rejection device, which then rejects the substandard segments. This invention not only improves the overall efficiency of the adhesive application process but also improves the quality of the finished product.

[0016] This invention can also adapt to different types of cigarette machines by pre-setting different operating information and different gluing parameters, thereby making the gluing mechanism more compatible with different types of cigarette machines and different specifications of cigarette paper.

[0017] This invention can also monitor the pressure of the gluing component, the glue supply component, and the glue path between them during the gluing process, and has an adjustment function that automatically adjusts the pressure before it returns to normal, thereby improving the safety of the gluing mechanism during operation.

[0023] Please see Figure 1 and Figure 2 , Figure 1This is an execution flowchart of a control method for an adhesive application mechanism provided in an embodiment of this application. Figure 2 This is a flowchart illustrating a control method for an adhesive application mechanism provided in an embodiment of this application. In this embodiment, the method includes: S101. When a gluing signal is received, enter the gluing mode.

[0024] The entity implementing this application may be the control system of the gluing mechanism.

[0025] In one embodiment of this application, before the gluing process begins, the cigarette paper is introduced into the paper guiding mechanism within the cigarette rolling machine, with the gluing component positioned facing the cigarette paper. When the cigarette paper begins rolling, the control system can control the gluing component to spray glue onto the cigarette paper. The control system receives the gluing signal specifically in the following ways: As a feasible implementation method, an automatic start-up mode is adopted. When the control system detects that the cigarette paper has started running, it controls the gluing component to start applying glue synchronously according to the predetermined gluing parameters.

[0026] As another feasible implementation method, a manual start mode is used. After the cigarette paper starts running, the operator inputs the gluing command or presses the gluing start button. After receiving the gluing command, the control system controls the gluing component to start gluing according to the predetermined gluing parameters.

[0027] As a preferred implementation, an automatic start mode and a manual start mode are used in combination. Operators can freely switch between the manual and automatic start modes. When the cigarette paper is first run, the automatic start mode can be used. If a situation arises during the gluing process that requires stopping the operation or a malfunction occurs, the automatic start mode can be switched to the manual start mode. This prevents automatic gluing from occurring while checking or troubleshooting, improving safety and the flexibility of the gluing mechanism during use.

[0028] In one possible implementation, before entering the gluing mode, the method further includes: Predefined standard rubber storage area; Obtain the glue storage quantity; Determine whether the amount of adhesive stored is within the standard adhesive storage range: If the amount of glue stored is within the standard glue storage range, then the glue application mode is entered; If the amount of glue stored is not less than the standard glue storage range, a glue discharge signal is issued; If the amount of glue stored is not greater than the standard glue storage range, a glue replenishment signal is issued.

[0029] In one embodiment of this application, before applying glue to the component, it is necessary to check whether the glue storage level in the glue supply component is sufficient to meet the glue application requirements. Specifically, the operator predefines a standard glue storage range in the control system based on the capacity of the glue supply component and the amount of glue to be applied. The standard glue storage range includes a maximum glue storage value and a minimum glue storage value. The maximum glue storage value can be adaptively adjusted according to the capacity of the glue supply component. To avoid glue overflow, the maximum glue storage value must be less than the capacity of the glue supply component. The minimum glue storage value can be adaptively adjusted according to the amount of glue to be applied. The glue in the glue supply component must at least meet the glue application requirements for one application.

[0030] After the gluing mechanism is activated but before entering the gluing mode, the control system obtains the current glue storage level in the supply component and then determines whether the glue storage level is within the preset standard glue storage range. If the glue storage level is within the standard glue storage range, the gluing mode is entered, because the glue storage level within the standard glue storage range means that the current glue storage level is sufficient for at least one gluing operation, allowing for at least one normal operation. Otherwise, two abnormal situations will occur: First, if the glue storage level is not less than the standard glue storage range (i.e., the glue storage level is not less than the maximum glue storage value), a glue discharge signal is issued, indicating to the operator that there is too much glue in the supply component and there is a risk of overflow. Second, if the glue storage level is not greater than the standard glue storage range (i.e., the glue storage level is not greater than the minimum glue storage value), a glue replenishment signal is issued, indicating to the operator that there is too little glue in the supply component and it cannot meet the gluing requirements, requiring glue replenishment.

[0031] For example, the total capacity of the glue supply unit can be 25 liters, and the standard glue storage range can be 5-23 liters, that is, the maximum glue storage value can be 23 liters, and the minimum glue storage value can be 5 liters. If the current glue storage in the glue supply unit is 20 liters, the glue application mode is entered, and the voice announcement "Entering glue application mode" is broadcast once and the green indicator light is constantly lit. If the current glue storage in the glue supply unit is 24 liters, a glue discharge signal is issued, and the voice announcement "Glue excess" is broadcast and the red indicator light is constantly lit. This continues until the glue storage is re-detected after discharge and is less than 23 liters, at which point the announcement stops and the yellow indicator light goes out. If the current glue storage in the glue supply unit is 2 liters, a glue replenishment signal is issued, and the voice announcement "Glue insufficient" is broadcast and the yellow indicator light is constantly lit. This continues until the glue storage is re-detected after replenishment and is greater than 5 liters, at which point the announcement stops and the yellow indicator light goes out.

[0032] In one possible implementation, before opening the adhesive application component, the method further includes: The operation information corresponding to various types of cigarette paper is predefined, and each type of cigarette paper is associated with the corresponding operation information. Based on the aforementioned operational information, corresponding gluing parameters are predefined, and each piece of operational information is associated with the corresponding gluing parameters. The gluing parameters include the amount of glue applied to the part being glued and the gluing speed of the part being glued. Obtain the current type of cigarette paper, and retrieve the corresponding operating information and the corresponding adhesive parameters.

[0033] In one embodiment of this application, different brands and specifications of cigarette machines and different types of cigarette paper require corresponding and compatible parameters for the gluing components, including the amount and speed of gluing. When changing to a different type of cigarette paper, or when installing this gluing mechanism on a cigarette machine of another brand, the gluing parameters need to be readjusted, increasing the workload and reducing production efficiency. Therefore, the operating information corresponding to common different types of cigarette machines and the gluing parameters corresponding to the specifications of various types of cigarette paper can be preset in the control system. Before each operation, the relevant information of the cigarette machine and the cigarette paper is obtained, and then the corresponding preset gluing parameters are directly called.

[0034] For example, the information about the cigarette machine could be the current rotational speed of the roller driving the cigarette paper, thereby calculating the running speed of the cigarette paper; the information about the cigarette paper could be the width and thickness of the cigarette paper, thereby determining the acceptable gluing range and amount for the current specification of cigarette paper, otherwise excessive gluing may cause glue to overflow onto the outside of the cigarette paper; the gluing parameters could be the amount of glue, the gluing range, and the spraying force. The spraying force can be changed by adjusting the relevant parameters of the compressed air in the gluing component. Multiple related gluing parameters can be preset according to common needs. When presetting the data, the information about the cigarette machine, the cigarette paper, and the gluing parameters that need to be used are associated. Before starting the gluing component, the current information about the cigarette machine and the cigarette paper is obtained first, then the relevant gluing parameters are directly called, and finally the gluing component is started.

[0035] As a feasible implementation method, different gluing requirements may exist for the same cigarette machine and the same type of cigarette paper. Therefore, different gluing parameters can be set according to different gluing requirements. After obtaining the relevant cigarette machine information and cigarette paper information, the gluing parameters corresponding to different gluing requirements are displayed in the human-machine interface. The operator can select the corresponding gluing parameters according to actual needs.

[0036] In one possible implementation, entering the gluing mode specifically includes: Step S11: Predefine a standard pressure range, which includes a maximum pressure value and a minimum pressure value; Step S12: Drive the cigarette paper to run and open the adhesive application part; Step S13: Obtain the real-time pressure value, wherein the real-time pressure value is the pressure value inside the connecting pipe between the adhesive application component and the adhesive supply component; Step S14: Determine whether the real-time pressure value is within the standard pressure range. If the real-time pressure value is within the standard pressure range, return to step S13.

[0037] In one embodiment of this application, since the adhesive is delivered via a glue supply tube, excessive pressure within the tube may cause it to rupture, while insufficient pressure indicates insufficient glue flow, meaning the adhesive may not be properly delivered to the gluing component. Therefore, to improve the safety and stability of adhesive delivery, the control system also needs to monitor the pressure inside the glue supply tube in real time; that is, a pressure sensor is installed on the glue supply tube between the gluing component and the glue supply component.

[0038] Specifically, the first step is to determine the tolerable pressure value inside the glue supply tube based on its material, size, and other parameters, as well as through multiple tests. A standard pressure range is then preset based on this tolerable pressure value as a reference for subsequent pressure testing. To ensure the safety of the glue supply tube during use, the maximum value of the preset standard pressure range can be slightly lower than the tolerable pressure value, serving as an early warning. The standard pressure range includes a maximum pressure value and a minimum pressure value. The maximum pressure value can be set with reference to the tolerable pressure value, while the minimum pressure value can be set based on the actual flow rate of glue in the glue supply tube and the amount of glue required for actual application. A real-time pressure value not exceeding the minimum pressure value indicates that the glue flow rate in the glue supply tube is insufficient for subsequent application. After the standard pressure range is preset, the control system drives the cigarette paper to run and simultaneously opens the compressed air valve and drive unit on the glue application component. The control system will acquire the real-time pressure value detected by the pressure sensor and then determine whether the real-time pressure value is within the standard pressure range.

[0039] In one possible implementation, step S14 specifically includes: Determine whether the real-time pressure value is within the standard pressure range: If the real-time pressure value is within the standard pressure range, then return to step S13; If the real-time pressure value is not less than the standard pressure range, then enter high-pressure mode; If the real-time pressure value is not greater than the standard pressure range, then enter low-pressure mode; The high-pressure mode includes shutting down all devices and outputting a high-pressure alarm; the low-pressure mode includes shutting down all devices and outputting a low-pressure alarm.

[0040] In one embodiment of this application, determining whether the real-time pressure value is within the standard pressure range will result in three scenarios: In the first case, when the current pressure value is detected to be within the standard pressure range, the adhesive is applied normally to the part, and the process returns to step S13, which is to obtain the next pressure value for judgment.

[0041] In the second scenario, when the detected current pressure value is outside the standard pressure range but not less than the maximum pressure value, it indicates excessive internal pressure in the glue supply hose. This may be due to blockages in the glue inlet of the glue applicator or within the glue supply hose itself, preventing the glue from being transported properly and thus causing excessive internal pressure. In this case, the control system puts the glue applicator into high-pressure mode and alerts the operator to troubleshoot and perform maintenance on the glue applicator and cigarette machine. High-pressure mode includes stopping the cigarette paper operation, closing the compressed air valve of the glue applicator, and stopping the drive unit. A high-pressure alarm is also output to remind the operator to troubleshoot and perform maintenance on the glue applicator and cigarette machine. The high-pressure alarm may include a voice announcement of "excessive internal pressure in the pipeline" and a flashing red light. The high-pressure alarm will stop when the control system re-acquires the current pressure value and it returns to within the standard pressure range.

[0042] As a feasible implementation method, a first self-calibration value is preset, and this first self-calibration value is positive. When the difference between the current pressure value and the maximum pressure value is not greater than the first self-calibration value, the system enters the high-pressure self-calibration mode; when the difference between the current pressure value and the maximum pressure value is greater than the first self-calibration value, the system enters the high-pressure mode. Before entering the high-pressure self-calibration mode, it is also necessary to check whether the adhesive is being dispensed from the adhesive application component. If the adhesive application component is dispensing adhesive normally, the system enters the high-pressure self-calibration mode provided that the difference between the current pressure value and the maximum pressure value is not greater than the first self-calibration value. If the adhesive application component is not dispensing adhesive, the preset first self-calibration value is ignored, and the system directly enters the high-pressure mode. In high-pressure self-calibration mode, if the glue application status of the glued component is detected to be normal, i.e., the glue dispensing amount is within the error range of the set standard value, the supply of glue from the glue supply device is reduced, i.e., the rotation speed of the drive unit is reduced, until the pressure inside the glue supply tube returns to the standard pressure range. If the glue application status of the glued component is detected to be abnormal, and the glue dispensing amount is lower than the error range of the set standard value, the glue dispensing amount is increased to the set standard value while keeping the glue supply constant, or the glue dispensing amount is increased to the set standard value while reducing the supply amount, until the pressure inside the glue supply tube returns to the standard pressure range. Generally speaking, when the glue dispensing amount of the glued component is greater than the preset standard value, the current glue supply amount also needs to be greater than the preset glue supply amount for excessive pressure inside the glue supply tube to occur. Therefore, when the pressure inside the glue supply tube is excessive, the glue dispensing amount will almost never exceed the preset standard value.

[0043] In the third scenario, when the detected current pressure value is outside the standard pressure range but not greater than the minimum pressure value, it indicates that the internal pressure of the glue supply hose is too low. This may be due to excessive glue output from the gluing component or insufficient glue in the glue supply component, resulting in insufficient glue flow within the hose. In this case, the control system will put the gluing mechanism into low-pressure mode and alert the operator to troubleshoot and perform maintenance on the gluing mechanism and cigarette machine. Low-pressure mode includes stopping the cigarette paper operation, closing the compressed air valve of the gluing component, and stopping the drive unit. A low-pressure alarm will be output to remind the operator to troubleshoot and perform maintenance on the gluing mechanism and cigarette machine. The low-pressure alarm may include a voice announcement of "Pipe internal pressure too low" and a flashing yellow light. The low-pressure alarm will stop when the control system re-acquires the current pressure value and it returns to the standard pressure range.

[0044] As a feasible implementation, a second self-calibration value is preset, and this second self-calibration value is positive. When the absolute value of the difference between the current pressure value and the minimum pressure value is detected to be not less than the second self-calibration value, the system enters a low-pressure self-calibration mode; when the absolute value of the difference between the current pressure value and the minimum pressure value is detected to be greater than the second self-calibration value, the system enters a low-pressure mode. Before entering the low-pressure self-calibration mode, it is also necessary to check whether the adhesive supply component is supplying adhesive. If the adhesive supply component is supplying adhesive normally, the system enters the low-pressure self-calibration mode if the absolute value of the difference between the current pressure value and the minimum pressure value is not less than the second self-calibration value; if the adhesive supply component is detected not supplying adhesive, the preset second self-calibration value is ignored, and the system directly enters the low-pressure mode. In low-pressure self-calibration mode, if the glue supply status of the glue applicator is detected to be normal, that is, the glue output is within the error range of the set standard value, the supply of the glue applicator is increased, that is, the speed of the drive unit is increased, until the pressure inside the glue supply tube returns to the standard pressure range; if the glue output of the glue applicator is detected to be higher than the error range of the set standard value, the glue output of the glue applicator is reduced, until the pressure inside the glue supply tube returns to the standard pressure range.

[0045] In one possible implementation, prior to step S12, a predefined glue filling value is also included.

[0046] In one embodiment of this application, since the amount of glue in the glue supply component decreases during operation, failure to replenish glue in time after the glue supply is empty will affect the gluing of the gluing component and may even damage the gluing component. Based on the actual amount of glue and the capacity of the glue supply component, a warning value, i.e., a glue replenishment value, is preset. When it is detected that the remaining amount in the glue supply component is not greater than the glue replenishment value, glue is replenished.

[0047] In one possible implementation, after step S12, the method further includes: Step S15: Obtain the current amount of glue stored; Step S16: Determine whether the current glue storage amount is greater than the glue replenishment value: If the current glue storage amount is greater than the glue replenishment value, then maintain the status quo and return to step S15; If the current glue storage level is not greater than the glue replenishment value, then enter maintenance mode; The maintenance mode includes shutting down all devices and outputting a low margin signal.

[0048] In one embodiment of this application, after the gluing process begins, the remaining glue level in the glue supply component needs to be monitored in real time to prevent dry spraying. Specifically, determining whether the current glue level exceeds the replenishment value includes two methods: As a feasible implementation method, manual observation is employed. An observation window is installed on the glue supply unit, and a corresponding scale line is set on the observation window according to the glue replenishment value. When the operator observes through the observation window that the glue level in the glue supply unit drops to the scale line, the operation of each device is paused, and then the glue in the glue supply unit is replenished to the required amount before the device is restarted.

[0049] As a preferred implementation, sensor detection is used. A sensor is installed inside the glue supply unit to detect the real-time liquid level, which is then converted into the current glue level. A preset glue replenishment value is used as a warning value. When the current glue level is detected to be less than the glue level, the operation of each device is paused, and a low glue level signal is output. The low glue level signal may include a flashing blue indicator light and a voice announcement saying "Insufficient glue level".

[0050] S102. Obtain the adhesive application image, wherein the adhesive application image is real-time image information of the cigarette paper after adhesive application.

[0051] In one embodiment of this application, since the gluing component is an automatic gluing system, the gluing effect may be affected by parameters such as the amount of glue applied and the spraying range during the gluing process. Therefore, it is also necessary to check whether the glued cigarette paper meets the process requirements. Therefore, a camera is installed downstream of the gluing component to capture gluing images. These images are real-time images taken after the cigarette paper is glued, and the gluing images and image acquisition time are stored for later retrieval.

[0052] As a feasible implementation method, a high-speed color camera can be used, with an integrated protective lens. This not only prevents damage to the lens of the high-speed color camera but also saves installation space for the lens protector. Simultaneously, a supplementary light can be placed near the high-speed color camera, pointing towards its shooting area to ensure clear image capture and facilitate the assessment of the adhesive application effect.

[0053] S103. Determine whether there is a defective segment in the glue application image. If the defective segment exists, mark the defective segment in the glue application image and simultaneously issue rejection information.

[0054] In one embodiment of this application, after the control system acquires the glued image captured by the camera, the image recognition module needs to identify whether there are any unqualified glued sections in the acquired image. If unqualified glued sections exist, they need to be marked first and then sent to the rejection device for removal. Specifically, a standard image is pre-stored in the control system for subsequent retrieval and comparison. The image recognition module processes the acquired image information through deep learning and compares it with the standard image to identify and mark the unqualified glued parts. The control system simultaneously sends the marked information to the rejection device, i.e., rejection information, and controls the rejection device to remove the corresponding unqualified cigarette paper sections with unqualified glued effects.

[0055] In one possible implementation, determining whether there are defective segments in the adhesive application image specifically includes: Based on the standard adhesive application image, determine whether the defective segment exists in the adhesive application image: If the defective segment exists in the glue application image, mark the defective segment in the glue application image and simultaneously issue a rejection message; If the defective segment is not present in the adhesive application image, then the cutting mode is entered.

[0056] In one embodiment of this application, a standard gluing image is preset in the control system. This standard image can be adjusted according to actual application conditions. It can be manually acquired and stored after gluing, or a suitable image can be selected and stored during the gluing process. The standard image can also be manually updated during the gluing process. Then, based on the preset standard image, the system identifies whether there are any defective segments in the acquired gluing image. If the image recognition module identifies a defective segment, it marks and stores the defective segment in the image, and the control system simultaneously sends rejection information to the rejection device. If the image recognition module does not identify a defective segment, the glued cigarette paper enters a slitting mode. Specifically, in the slitting mode, the starting point of the gluing process is used as the slitting starting point, and a preset segment length is used as the slitting interval. The starting point of the gluing process is the starting point of the first gluing process.

[0057] As a feasible implementation method, the acquired adhesive application images can be displayed on a human-machine interface (HMI). This allows for the identification of defective sections not only through an image recognition module but also through manual inspection. Operators can manually check for defective sections by viewing the adhesive application images on the HMI. If defective sections are found, they can be manually selected and marked on the HMI. After marking, the control system sends rejection information to the rejection device.

[0058] S104. Based on the running information of the cigarette paper, determine the running position of the unqualified segment. When the unqualified segment reaches the rejection position, reject the unqualified segment. The running information includes the running speed of the cigarette paper and the segment length when the cigarette paper is cut after being glued.

[0059] In one embodiment of this application, the running position of the defective segment can be calculated by using the running information of the cigarette paper, namely the running speed of the cigarette paper, and the known running distance between the adhesive area and the rejection area, so that the rejection device can reject the defective segment.

[0060] In one possible implementation, determining the running position of the defective segment based on the cigarette paper's running information, and removing the defective segment when it reaches the rejection position, specifically includes: The segment length is predefined, and the starting point of the initial gluing is marked as the cutting start point. The cutting start point is used as the initial cutting position, and every segment length is marked as a cutting point. Determine the starting position and the ending position, wherein the starting position is the running position of the beginning end of the non-conforming segment, and the ending position is the running position of the ending end of the non-conforming segment; Obtain the cutting point closest to the starting position; When the cutting point reaches the rejection position, the cigarette paper corresponding to the cutting point and the end position is rejected.

[0061] In one embodiment of this application, the glued cigarette paper generally needs to be cut into multiple segments before subsequent processes. Therefore, the segment length can be preset before cutting according to actual application conditions, and the starting point of the initial glue application is the starting point of the first cutting. In the cutting mode, cigarette paper without defective segments will be cut once at preset segment length intervals, starting from the cutting starting point. If defective segments exist, before the defective segments enter the cutting mode, the rejection device will reject the cigarette paper by using the cutting point closest to the beginning of the defective segment as the rejection starting point and the end of the defective segment as the rejection ending point.

[0062] In one possible implementation, after removing the cigarette paper corresponding to the cutting point and the end position, the method further includes marking the end position as the cutting start point and cutting the cigarette paper based on the running speed and the segment length.
