Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, and in particular to a method, apparatus, equipment, medium, and product for correcting the deviation of tipping paper in a cigarette machine. Background Technology

[0002] Tipping paper, also known as tipping paper, is a special type of paper used to wrap cigarette filters, serving to connect the cigarette and the filter. During transport, tipping paper can shift due to various reasons, and this shift directly affects the quality of cigarette production. Specifically, shifting tipping paper leads to deviations in the length of the tipping paper in the finished cigarette, resulting in substandard cigarettes with tipping paper that is too long or too short. It can also cause glue overflow or insufficient glue application, affecting the quality of the finished cigarettes and even causing abnormal shutdowns of the cigarette rolling machine.

[0003] Currently, the main methods for correcting the deviation of tipping paper are manual correction and stepper motor correction. Manual correction requires operators to monitor the conveying status of the tipping paper in real time and then adjust the position of the tipping paper tray or the tipping paper position on the conveyor line to change the degree of deviation. Stepper motor correction detects the deviation of the tipping paper before it enters the paper cutting wheel, and then uses a stepper motor to adjust the position of the paper guide block according to the deviation detection result to achieve automatic correction of the tipping paper.

[0004] However, manual correction requires operators to continuously monitor and repeatedly adjust the degree of deviation of the tipping paper. The correction work is intensive and lacks real-time capability. The tipping paper needs to pass through multiple parts, and the comprehensiveness of manual monitoring is limited, resulting in limited correction effect and cigarette production quality. Stepper motor correction will change the position of the guide block. The change in the center line of the guide block will cause the guide block and the cutter to be no longer on the same baseline, affecting the length of the tipping paper inside and outside when the cigarette is cut, resulting in the production of substandard cigarettes with tipping paper that is too long or too short. Summary of the Invention

[0005] This invention provides a method, apparatus, equipment, medium, and product for correcting the offset of tipping paper in a cigarette machine. It can determine the offset of the tipping paper based on the measured contour data of the tipping paper in the cigarette machine, and then adjust the position of the tipping paper tray according to the offset. By adjusting the position of the tipping paper tray, the paper output range of the tipping paper tray is changed, thereby reducing the degree of offset of the tipping paper. This achieves the purpose of automatic, low-cost, high-efficiency, and high-precision correction of tipping paper, ensuring the quality of cigarette production while reducing the cost of cigarette production.

[0006] According to one aspect of the present invention, a method for correcting the deviation of tipping paper in a cigarette machine is provided, the method comprising: Based on the equipment operation data of the cigarette machine, a first offset information detector for the tipping paper of the cigarette machine is determined, wherein the first offset information detector is a first tipping paper profile detector deployed at the inlet of the paper pressing roller of the cigarette machine and / or a second tipping paper profile detector deployed at the outlet of the paper pressing roller of the cigarette machine. Based on the baseline of the tipping paper of the cigarette machine and the size information of the tipping paper, the reference contour data of the tipping paper of the cigarette machine is determined. Based on the tipping paper offset threshold, the reference contour data and the measured contour data of the tipping paper of the cigarette machine, the tipping paper tray to be adjusted and the displacement data of the tipping paper tray to be adjusted are determined. Among them, the measured contour data are the first tipping paper contour data detected by the first tipping paper contour detector and / or the second tipping paper contour data detected by the second tipping paper contour detector. The position of the tipping paper tray to be adjusted is adjusted based on the displacement data of the tipping paper tray to reduce the offset of the tipping paper in the cigarette machine.

[0007] According to another aspect of the present invention, a device for correcting the deviation of cigarette machine tipping paper is provided. This device is used to implement the method for correcting the deviation of cigarette machine tipping paper in any embodiment of the present invention. The device includes: The detector determination module is used to determine the first offset information detector of the cigarette machine tipping paper based on the equipment operation data of the cigarette machine, wherein the first offset information detector is a first tipping paper profile detector deployed at the inlet of the cigarette machine pressure roller and / or a second tipping paper profile detector deployed at the outlet of the cigarette machine pressure roller. The displacement parameter determination module is used to determine the reference contour data of the cigarette machine's tipping paper based on the tipping paper baseline and the size information of the tipping paper in the cigarette machine, and to determine the displacement data of the tipping paper tray to be adjusted and the tipping paper tray to be adjusted based on the tipping paper offset threshold, the reference contour data, and the measured contour data of the tipping paper in the cigarette machine; wherein, the measured contour data are the first tipping paper contour data detected by the first tipping paper contour detector and / or the second tipping paper contour data detected by the second tipping paper contour detector; The tipping paper correction module is used to adjust the position of the tipping paper tray based on the displacement data of the tray to be adjusted, so as to reduce the offset of the tipping paper in the cigarette machine.

[0008] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising: At least one processor; and a memory communicatively connected to the at least one processor; The memory stores a computer program that can be executed by at least one processor, which enables the at least one processor to perform the method for correcting the tipping paper of a cigarette machine according to any embodiment of the present invention.

[0009] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the method for correcting the tipping paper of a cigarette machine according to any embodiment of the present invention.

[0010] According to another aspect of the present invention, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the method for correcting the deviation of the tipping paper in a cigarette machine according to any embodiment of the present invention.

[0011] The method for correcting the tipping paper of a cigarette machine according to the present invention includes: determining a first offset information detector for the tipping paper of the cigarette machine based on the equipment operation data of the cigarette machine; the first offset information detector is a first tipping paper profile detector deployed at the inlet of the cigarette machine's paper pressing roller and / or a second tipping paper profile detector deployed at the outlet of the cigarette machine's paper pressing roller; determining reference profile data of the tipping paper of the cigarette machine based on the tipping paper baseline and the size information of the tipping paper of the cigarette machine; and determining the tipping paper tray to be adjusted and the displacement data of the tipping paper tray to be adjusted based on the tipping paper offset threshold, the reference profile data, and the measured profile data of the tipping paper of the cigarette machine; the measured profile data is the first tipping paper profile data detected by the first tipping paper profile detector and / or the second tipping paper profile data detected by the second tipping paper profile detector; and adjusting the position of the tipping paper tray to be adjusted based on the displacement data of the tipping paper tray to be adjusted, so as to reduce the offset of the tipping paper of the cigarette machine. The technical solution of this invention can determine the offset of the tipping paper based on the tipping paper baseline, the size information of the tipping paper in the cigarette machine, and the tipping paper contour data detected by at least one tipping paper contour detector. Then, the position of the tipping paper tray is adjusted according to the offset, thereby changing the paper output range of the tipping paper tray. This achieves automated, low-cost, high-efficiency, and high-precision correction of the tipping paper, reducing the degree of tipping paper offset and ensuring cigarette production quality while reducing production costs. It solves the problems of manual correction requiring continuous monitoring and repeated adjustment of the tipping paper offset, which is intensive and lacks real-time capability. Furthermore, manual monitoring is limited due to the tipping paper passing through multiple components, resulting in limited correction effectiveness and cigarette production quality. It also solves the problem that stepper motor correction can change the position of the guide block, causing the guide block and cutter to be out of alignment, affecting the length of the tipping paper during cigarette cutting and leading to substandard cigarettes with excessively long or short tipping paper.

[0019] For medium-speed cigarette machines without a correction system, the correction methods for tipping paper include manual correction, stepper motor correction, and the installation of an automatic correction system. However, automatic correction systems are generally designed for high-speed cigarette machines. The feeding principle of tipping paper differs significantly between medium-speed and high-speed cigarette machines. For example, high-speed cigarette machines do not have guide blocks, and the tipping paper is coated by spraying. If an automatic correction system is installed on the tipping paper transport path of a medium-speed cigarette machine, the correction effect of the automatic correction system is limited under the influence of the pressure roller and guide block, resulting in low practicality and high cost.

[0020] Figure 1 This is a structural schematic diagram of a cigarette rolling machine provided by the present invention. Figure 1 The cigarette machine shown can be used to implement the cigarette machine tipping paper correction method of the present invention, see reference. Figure 1The cigarette rolling machine includes a tipping paper tray 1, a tipping paper confluence point 2, a cigarette rolling machine pressing roller 3, a gluing assembly 4, a cigarette rolling machine guide block 5, a cigarette rolling machine cutting roller 6, and a cigarette rolling machine cutter 7. The tipping paper tray 1 comprises two trays, which serve as a backup for each other, continuously supplying tipping paper to ensure the continuity of cigarette rolling operations. The cigarette paper output from both trays is conveyed through the tipping paper confluence point 2 to the cigarette rolling machine pressing roller 3, then through the gluing assembly 4 and the cigarette rolling machine guide block 5 to the cigarette rolling machine cutting roller 6. After the cigarette rolling machine cutting roller 6 performs the tipping paper cutting task, it continues to perform the corresponding cigarette splicing task. Finally, the cigarette rolling machine cutter 7 performs the cutting task, separating the "cigarette-tip filter-cigarette" structure into two cigarettes. The straightness and correction effect of the tipping paper are particularly important to the production quality of the cigarettes. It is worth noting that the purpose of having the cigarette paper output from both paper trays pass through the tipping paper confluence point 2 is to set the same forward path for the two paper trays so that the tipping paper can be spliced ​​when changing paper trays, and to continuously feed the tipping paper to the paper pressing roller 3 and subsequent components of the cigarette machine, thereby reducing the impact of adjusting the paper trays on the cigarette making process.

[0021] Figure 2 This is a flowchart illustrating a method for correcting the offset of tipping paper in a cigarette machine according to the present invention. This embodiment can adjust the offset of the tipping paper in a low-cost, high-efficiency, and high-precision manner without changing the pre-calibrated positions of the cigarette-rolling and cutting components in the cigarette machine, thereby improving the production quality of cigarettes. This method can be executed by the tipping paper correction device provided by the present invention. This device can be implemented in hardware and / or software. In a specific embodiment, the device can be integrated into an electronic device. The following embodiments will illustrate this using the integration of the device into an electronic device as an example. (Refer to...) Figure 2 The method specifically includes the following steps: S101. Based on the equipment operation data of the cigarette machine, determine the first offset information detector of the cigarette machine tipping paper.

[0022] Combination Figure 1It is understood that the cigarette machine of the present invention includes two tipping paper trays. The equipment operation data of the cigarette machine can be understood as data related to the tipping paper conveying condition in the cigarette machine, including but not limited to the tipping paper tray currently in operation in the cigarette machine, the tipping paper attribute information and usage status of the currently operating tipping paper tray. The tipping paper attribute information includes the width information, material information, length information, etc. of the tipping paper. The usage status of the tipping paper can be understood as the length data of the tipping paper that has been used. Combining the length information of the tipping paper, the remaining amount of tipping paper can be determined so as to calculate the replacement time of the tipping paper tray, the splicing time of the tipping paper and the splicing method, aiming to continuously provide a continuous supply of tipping paper to the cigarette machine pressing roller and subsequent components. The tipping paper in a cigarette rolling machine can be understood as the tipping paper being transported within the machine, specifically the tipping paper output from the currently running tipping paper tray. The first offset information detector can be understood as a monitoring device that detects the transmission data of the tipping paper, such as an ultrasonic edge sensor, an infrared laser sensor, or an image acquisition device. Based on the tipping paper transmission data detected by the first offset information detector, the position of the tipping paper on the tipping paper transport line can be determined, thereby determining whether the tipping paper has shifted and by how much. This allows for real-time dynamic adjustment of the paper output position of the tipping paper tray, reducing the degree of tipping paper shift and ensuring the quality of cigarette slitting.

[0023] The first offset information detector is a first tipping paper profile detector deployed at the inlet of the cigarette machine's paper pressing roller and / or a second tipping paper profile detector deployed at the outlet of the cigarette machine's paper pressing roller. That is, at least one of the first tipping paper profile detector deployed at the inlet of the cigarette machine's paper pressing roller and the second tipping paper profile detector deployed at the outlet of the cigarette machine's paper pressing roller can be adaptively selected as an information detector to monitor the offset of the tipping paper.

[0024] Specifically, the usage rules for the first and second tipping paper profile detectors can be as follows: A specific tipping paper profile detector can monitor a specific tipping paper tray, for example, the first tipping paper profile detector detects tipping paper tray 1, and the second tipping paper profile detector detects tipping paper tray 2; a specific tipping paper profile detector can be used at a specific time, for example, the first tipping paper profile detector can be used from 8:00 to 14:00, and the second tipping paper profile detector can be used from 14:00 to 20:00; a specific location can be used to monitor tipping paper under specific working conditions, for example, the first tipping paper profile detector deployed at the inlet of the cigarette machine's pressure roller can detect relatively flat tipping paper, and the second tipping paper profile detector deployed at the outlet of the cigarette machine's pressure roller can detect pressure. For uneven and flat tipping paper, accurate offset data can be obtained; furthermore, the tipping paper profile detector can be determined based on the remaining amount of tipping paper. For example, when the remaining amount of tipping paper is less than X meters (X is related to the tipping paper monitoring logic), the first tipping paper profile detector and the second tipping paper profile detector are used to monitor the offset of the tipping paper tray. When the remaining amount of tipping paper is not less than X meters, the first tipping paper profile detector or the second tipping paper profile detector can be used adaptively to monitor the offset of the tipping paper tray (it is possible to control the detector with the shorter working time among the first and second tipping paper profile detectors to monitor the offset of the tipping paper tray, or to control the detector with the longer rest time among the first and second tipping paper profile detectors to monitor the offset of the tipping paper tray).

[0025] Furthermore, based on the equipment operation data of the cigarette machine, the first offset information detector for the cigarette machine's tipping paper is determined, including: based on the equipment operation data, determining the current tipping paper tray and the remaining amount of tipping paper on the current tipping paper tray; determining whether the remaining amount of tipping paper is less than the tipping paper remaining amount threshold; if the remaining amount of tipping paper is less than the tipping paper remaining amount threshold, then the first offset information detector is determined to be the first tipping paper contour detector and the second tipping paper contour detector; if the remaining amount of tipping paper is not less than the tipping paper remaining amount threshold, then the first offset information detector is determined by searching in the correspondence between the tipping paper tray and the offset information detector using the identification information of the current tipping paper tray.

[0026] The equipment operation data includes the currently operating tipping paper tray in the cigarette machine (i.e., the current tipping paper tray), the tipping paper attribute information of the currently operating tipping paper tray (e.g., the type, size, and specifications of the tipping paper on the tray), and the usage status (e.g., the cumulative running time and cumulative paper output length of the current tipping paper tray after paper replacement). The tipping paper balance threshold is a pre-set condition for initiating a tipping paper tray switching task. When the remaining tipping paper in the current tipping paper tray is less than the tipping paper balance threshold, the remaining tipping paper information of the current tipping paper tray is monitored in real time, and the standby tipping paper tray is controlled to prepare for splicing tipping paper. After splicing, the standby tipping paper tray becomes the current tipping paper tray, and a paper shortage warning is issued so that the staff can add tipping paper to the tipping paper tray, ensuring the continuity of the tipping paper conveying operation. It is worth noting that switching the tipping paper tray involves calibrating the positions of two tipping paper trays. Therefore, the first offset information detector is determined to be both the first and second tipping paper contour detectors. That is, the two tipping paper contour detectors work together to perform the tipping paper correction, ensuring the quality of the correction. If the remaining amount of tipping paper is not less than the tipping paper remaining amount threshold, the first offset information detector is determined by searching the correspondence between the tipping paper tray and the offset information detector using the current tipping paper tray's identification information.

[0027] Specifically, the correspondence between the tipping paper tray and the offset information detector can be understood as a pre-defined component correspondence. For example, the first tipping paper contour detector detects tipping paper tray 1, and the second tipping paper contour detector detects tipping paper tray 2. The purpose of this setup is to quickly obtain the detector to perform the correction task by looking up a table, thereby improving correction efficiency and quality. Furthermore, when the remaining amount of tipping paper is not less than the tipping paper remaining threshold, a specific tipping paper contour detector can be used at a specific time, or a tipping paper contour detector at a specific location can be used to monitor tipping paper under specific working conditions. This invention does not limit this aspect.

[0028] S102. Based on the baseline of the tipping paper of the cigarette machine and the size information of the tipping paper of the cigarette machine, determine the reference contour data of the tipping paper of the cigarette machine, and based on the tipping paper offset threshold, the reference contour data and the measured contour data of the tipping paper of the cigarette machine, determine the tipping paper tray to be adjusted and the displacement data of the tipping paper tray to be adjusted of the cigarette machine.

[0029] The tipping paper baseline can be understood as the center line on the tipping paper transport track. Ideally, the tipping paper should be symmetrically distributed along the baseline, ensuring that the tipping paper on two cigarettes after cutting is identical. However, in actual production, due to environmental factors and equipment mechanical errors, the tipping paper will not be symmetrically distributed along the baseline, resulting in a certain deviation. If the deviation is large, it will affect the production quality of the cigarettes. Therefore, real-time monitoring and correction are necessary to ensure the production quality of the cigarettes. The dimensional information of the tipping paper in the cigarette machine can be understood as the length and width information of the tipping paper on the current tipping paper tray in the cigarette machine. The width refers to the side of the tipping paper output from the tipping paper tray that is perpendicular to the tipping paper baseline, and the length information refers to the number of meters of tipping paper on the tipping paper tray. The reference contour data of the tipping paper in the cigarette machine can be understood as the ideal position of the tipping paper on the tipping paper transport track, that is, the contour lines on both sides of the tipping paper baseline, using the tipping paper baseline as a reference and half of the tipping paper width information as a measurement standard. The tipping paper offset threshold can be understood as the maximum tipping paper offset value preset according to the cigarette manufacturing logic. When the tipping paper offset exceeds the threshold, it is considered that the offset will affect the cigarette production quality, and correction is required. When the offset does not exceed the threshold, it is considered that the offset is within the allowable range and will not affect the cigarette production quality, so correction is not required. The measured contour data of the cigarette machine tipping paper can be understood as the contour information of the cigarette machine tipping paper on the tipping paper transport track detected by the first offset information detector. The tipping paper tray to be adjusted in the cigarette machine generally refers to the tipping paper tray currently in operation in the cigarette machine, i.e., the current tipping paper tray. The purpose of this setting is to achieve personalized position control. In special cases, in order to ensure that the main and backup tipping paper trays are always in the same axis, the tipping paper tray to be adjusted in the cigarette machine can be all the tipping paper trays in the cigarette machine. This setting can ensure the splicing quality of the tipping paper. The displacement data of the tipping paper disc to be adjusted can be understood as the adjustment parameters of the tipping paper disc to be adjusted, including but not limited to the adjustment direction and adjustment distance.

[0030] The measured contour data refers to the first water-filled paper contour data detected by the first water-filled paper contour detector and / or the second water-filled paper contour data detected by the second water-filled paper contour detector. It is worth noting that if the measured contour data consists of the first water-filled paper contour data detected by the first water-filled paper contour detector and the second water-filled paper contour data detected by the second water-filled paper contour detector, the first and second water-filled paper contour data can be processed separately. If both are normal, no correction is needed; otherwise, a correction strategy is formulated by combining the two water-filled paper contour data to ensure that the adjusted first and second water-filled paper contour data are both within the normal range. Alternatively, the offset trend of the water-filled paper can be analyzed based on the first and second water-filled paper contour data, and then a correction strategy can be formulated based on the offset trend. This invention does not limit this approach.

[0031] Specifically, based on the tipping paper baseline and the tipping paper size information of the cigarette machine, the reference contour data of the tipping paper of the cigarette machine is determined, including: based on the tipping paper size information of the cigarette machine, determining the short side data (i.e., width information) of the tipping paper of the cigarette machine; and based on the tipping paper baseline and the short side data, determining the first reference contour line and the second reference contour line of the tipping paper of the cigarette machine.

[0032] The first reference contour line and the second reference contour line are located on both sides of the tipping paper baseline, and the first distance between the first reference contour line and the tipping paper baseline is the same as the second distance between the second reference contour line and the tipping paper baseline.

[0033] The measured profile data includes a first measured profile line and a second measured profile line. The first measured profile line corresponds to the first reference profile line, which means that the first measured profile line and the first reference profile line are located on the same side of the tipping paper baseline. The second measured profile line corresponds to the second reference profile line, which means that the second measured profile line and the second reference profile line are located on the same side of the tipping paper baseline. Figure 3 This is a schematic diagram of the offset state of cork paper provided by the present invention. Figure 3 The arrows in the diagram indicate the direction of tipping paper transport; 8 represents the tipping paper transport track; 9 represents the tipping paper itself; 10 represents the first measured profile line; 11 represents the second measured profile line; 12 represents the tipping paper baseline; 13 represents the first reference profile line; and 14 represents the second reference profile line. Figure 3 The relative positional relationship between each outline and the water-tip paper baseline can be seen.

[0034] Furthermore, based on the tipping paper offset threshold, reference contour data, and measured contour data of the tipping paper in the cigarette machine, the tipping paper tray to be adjusted and its displacement data are determined, including: identifying the tipping paper tray currently in operation in the cigarette machine as the tipping paper tray to be adjusted; determining the first offset of the tipping paper in the cigarette machine based on the first measured contour line and the first reference contour line, and determining the second offset of the tipping paper in the cigarette machine based on the second measured contour line and the second reference contour line; when the first offset and the second offset are less than the tipping paper offset threshold, it is determined that the tipping paper tray to be adjusted does not need to be adjusted; when the first offset and the second offset are not less than the tipping paper offset threshold, the adjustment direction and adjustment scale of the tipping paper tray to be adjusted are determined based on the first offset and the second offset.

[0035] The first offset of the cigarette machine tipping paper can be understood as the offset between the first measured contour line and the first reference contour line. Ideally, the offset between the first measured contour line and the first reference contour line is 0. The second offset of the cigarette machine tipping paper can be understood as the offset between the second measured contour line and the second reference contour line. Ideally, the offset between the second measured contour line and the second reference contour line is 0. Generally, the first and second offsets are numerically the same. When the first and second offsets are less than the tipping paper offset threshold, it indicates that the offset of the tipping paper is within the specified range and will not affect the production quality of cigarettes, so no correction is needed. When the first and second offsets are not less than the tipping paper offset threshold, it is considered that the offset of the tipping paper is too large and needs to be adjusted; otherwise, unqualified cigarettes will be produced. At that time, the adjustment direction and adjustment scale of the tipping paper tray to be adjusted will be determined based on the first and second offsets. For example, the adjustment scale of the tipping paper tray to be adjusted can be determined by the first offset, the second offset, or the average of the first and second offsets. The opposite direction of the offset of the first or second offset can be determined as the adjustment direction of the tipping paper tray to be adjusted. That is, when the tipping paper is offset to the left, the axis of the tipping paper tray needs to be shifted to the right, and when the tipping paper is offset to the right, the axis of the tipping paper tray needs to be shifted to the left.

[0036] It is worth noting that when the first offset includes at least three first sub-offsets and the second offset includes at least three second sub-offsets, the adjustment direction and adjustment scale of the tipping paper disc to be adjusted are determined based on the first offset and the second offset, including: determining the offset trend of the tipping paper of the cigarette machine based on at least three first sub-offsets and at least three second sub-offsets; and determining the adjustment direction and adjustment scale of the tipping paper disc to be adjusted based on the offset trend.

[0037] The first sub-offset and the second sub-offset are in one-to-one correspondence. The first and second offsets in the above case include multiple contour information measured continuously. The purpose of this setting is to analyze the offset trend of the tipping paper in the cigarette machine, so as to determine the adjustment direction and adjustment scale of the tipping paper tray to be adjusted according to the offset trend of the tipping paper in the cigarette machine, adjust the tipping paper tray in advance, improve the correction effect of the tipping paper, and reduce the impact of the offset phenomenon on the cigarette production task. When calculating the offset trend, it is not required that every sub-offset is greater than the tipping paper offset threshold. For example, the current position data of the tipping paper is read every 10ms and stored in a queue of length 50 to form an offset data sequence. Each time a new acquisition is performed, a linear regression analysis is performed on the sequence to calculate the slope K. If the K value is consistently positive and greater than the positive trend threshold (a right skew threshold), it is determined that the tipping paper has a continuous rightward offset trend. Similarly, if the K value is consistently positive and greater than the negative trend threshold (a left skew threshold), it is determined that the tipping paper has a continuous leftward offset trend. Even if the current offset is less than the tipping paper offset threshold, an early warning will be issued and a fine-tuning task will be initiated. The advantage of this setting is that by analyzing the changing trend of the tipping paper, a leap from "passive correction" to "active prevention" can be achieved. Actions can be taken in advance when the tipping paper outline has not yet shifted significantly, greatly improving the stability of the system.

[0038] It is worth noting that all data detected by this invention can be smoothed using a Kalman filter to improve the signal-to-noise ratio and thus enhance the accuracy of the correction work.

[0039] Optionally, after determining the tipping paper tray to be adjusted and its displacement data in the cigarette machine, the correction method of the present invention further includes: using a third tipping paper contour detector deployed at the inlet of the cigarette machine's paper cutting wheel to detect the verification contour data of the cigarette machine's tipping paper; determining whether the cigarette machine's tipping paper meets the tipping paper output conditions based on the verification contour data and the tipping paper offset threshold; if the cigarette machine's tipping paper does not meet the tipping paper output conditions, determining whether the cigarette machine's tipping paper meets the tipping paper position adjustment conditions based on the verification contour data and the tipping paper offset threshold; when the cigarette machine's tipping paper meets the tipping paper position adjustment conditions, updating the displacement data of the tipping paper tray to be adjusted based on the tipping paper offset threshold, reference contour data, measured contour data, and verification contour data; when the cigarette machine's tipping paper does not meet the tipping paper position adjustment conditions, generating abnormal transmission information of the cigarette machine's tipping paper, and controlling the information interaction interface to display the abnormal transmission information.

[0040] The third tipping paper contour detector can be an ultrasonic edge sensor or an infrared laser sensor (determining the edge of the tipping paper by the position of the reflected or transmitted light spot). The verification contour data can be understood as the tipping paper contour data detected by the third tipping paper contour detector. The tipping paper output condition is the basis for judging whether the tipping paper can ensure the quality of cigarette slitting. When the tipping paper offset indicated in the verification contour data is less than the tipping paper offset threshold, it is considered that the offset of the tipping paper is very small and will not affect the cigarette slitting effect. In this case, it is determined that the cigarette machine's tipping paper meets the tipping paper output condition. Conversely, when the tipping paper offset indicated in the verification contour data is not less than the tipping paper offset threshold, it is considered that the offset of the tipping paper will affect the cigarette slitting effect, and it is determined that the cigarette machine's tipping paper does not meet the tipping paper output condition. The tipping paper position adjustment condition can be understood as the basis for measuring whether the tipping paper needs to be adjusted. Generally, this invention will carry out secondary adjustments for short-term, minor deviations to ensure the continuity of cigarette production and reduce the impact of downtime on cigarette production. In cases where no adjustment is necessary, such as prolonged offset (which can be determined based on a pre-set time threshold), excessive offset (which can be determined based on a pre-set fault offset threshold), or abnormal measured contour data but faulty verification contour data (which can be considered as a possible axial asymmetry in the equipment itself), abnormal transmission information of the cigarette machine's tipping paper will be generated. The abnormal transmission information will be displayed on the control information interaction interface to inform the staff that the cigarette machine is faulty so that the staff can repair the cigarette machine. At the same time, the current cigarette production task will be stopped to avoid continuously producing unqualified cigarettes and wasting resources.

[0041] In a specific example, the conditions for generating abnormal transmission information of the tipping paper in a cigarette machine can be that the tipping paper deviates within three consecutive detection cycles. The warning methods for abnormal transmission information include, but are not limited to, audible and visual alarms. At the same time as the audible and visual alarm, a rejection signal can also be sent to the main control system of the cigarette machine so that the main control system of the cigarette machine can reject the unqualified cigarettes produced during that time period.

[0042] When the tipping paper of the cigarette machine meets the tipping paper position adjustment conditions, the displacement data of the tipping paper tray to be adjusted is updated based on the tipping paper offset threshold, reference contour data, measured contour data, and verification contour data. The update method for the displacement data of the tipping paper tray to be adjusted is to formulate a correction strategy by comprehensively considering the two tipping paper contour data and the reference contour data, ensuring that the first tipping paper contour data, the second tipping paper contour data, and the reference contour data of the adjusted tipping paper are all within the normal range. That is, the position adjustment data that simultaneously makes the first tipping paper contour data, the second tipping paper contour data, and the reference contour data within the normal range is determined as the displacement data of the tipping paper tray to be adjusted. Alternatively, the offset trend of the tipping paper can be analyzed based on the first tipping paper contour data, the second tipping paper contour data, and the reference contour data, and then a correction strategy can be formulated based on the offset trend. This invention does not limit this approach. The advantage of this setting is that the position of the tipping paper can be re-checked, thereby improving the cutting quality of cigarettes.

[0043] Furthermore, the tipping paper contour data detected by the third tipping paper contour detector of this invention can be used not only for secondary verification but also for formulating correction strategies. That is, after the cigarette machine is running, the adjustment method of the tipping paper tray is determined based on the tipping paper contour data detected by the third tipping paper contour detector and the measured contour data of the tipping paper detected by the first offset information detector. This is equivalent to determining the correction method of the tipping paper based on the tipping paper contour data at the pressure roller and the tipping paper contour data at the cutting roller. This can take into account the mechanical errors of the equipment as much as possible, ensure the transmission quality of the tipping paper, and thus improve the cigarette slitting effect.

[0044] S103. Adjust the position of the tipping paper tray to be adjusted based on the displacement data of the tipping paper tray to be adjusted, so as to reduce the offset of the tipping paper in the cigarette machine.

[0045] Specifically, adjusting the position of the tipping paper tray based on its displacement data can be understood as translating the tipping paper tray according to the adjustment direction and adjustment scale in the displacement data, so as to change the current position and paper output position of the tipping paper tray, thereby reducing the offset of the tipping paper in the cigarette machine.

[0046] For example, the tipping paper tray to be adjusted is tipping paper tray 1. The adjustment direction in the displacement data of the tipping paper tray to be adjusted is the right side of the tipping paper conveying direction, and the adjustment scale is 0.5 cm. Then, the axial position of tipping paper tray 1 is shifted 0.5 cm to the right side of the tipping paper conveying direction, so that the tipping paper output by tipping paper tray 1 can be shifted 0.5 cm to the right side of the tipping paper conveying direction.

[0047] The correction action of the present invention can be performed by an axial servo adjustment device. This device can respond to the displacement data of the tipping paper tray to be adjusted and adjust the position of the tipping paper tray in a closed-loop control manner. For example, the servo motor in the axial servo adjustment device is controlled to rotate a specific angle (related to the displacement data of the tipping paper tray to be adjusted), and the tipping paper tray shaft is driven to move a corresponding displacement through the lead screw and nut mechanism to complete a dynamic calibration.

[0048] The technical solution described in the above embodiments can determine the offset of the tipping paper based on the tipping paper baseline, the size information of the tipping paper in the cigarette machine, and the tipping paper contour data detected by at least one tipping paper contour detector. Then, the position of the tipping paper tray is adjusted according to the offset, thereby changing the paper output range of the tipping paper tray. This achieves automated, low-cost, high-efficiency, and high-precision correction of the tipping paper, reducing the degree of tipping paper offset and ensuring cigarette production quality while reducing production costs. Secondly, the correction position of this invention is near the pressure roller. By moving the correction position forward, it effectively avoids changes in the mechanical reference and does not affect the reference of the guide block. Combined with early detection and trend prediction, preventative correction is achieved, ensuring cigarette slitting quality. Furthermore, the correction method of this invention is a closed-loop servo correction method, which can achieve high-precision and high-stability correction, reducing the scrap rate of cigarettes and improving the utilization rate of cigarette resources. This solution addresses the problems of manual correction requiring continuous monitoring and repeated adjustments to the tipping paper's offset, which is intensive, lacks real-time capability, and limits the comprehensiveness of manual monitoring due to the tipping paper's passage through multiple components, resulting in limited correction effectiveness and cigarette production quality. It also solves the problem of stepper motor correction altering the position of the guide block, causing the guide block and cutter to be out of alignment, affecting the length of the tipping paper during cigarette slitting and leading to substandard cigarettes with excessively long or short tipping paper. Secondly, at least one tipping paper profile detector in this invention can be any of the following: 1. A first tipping paper profile detector deployed at the inlet of the cigarette machine's paper pressing roller; 2. A second tipping paper profile detector deployed at the outlet of the cigarette machine's paper pressing roller; 3. A first tipping paper profile detector deployed at the inlet of the cigarette machine's paper pressing roller and a second tipping paper profile detector deployed at the outlet of the cigarette machine's paper pressing roller; 4.
