Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cigarette production equipment, and in particular to a visual monitoring device for preventing cigarettes from smoldering. Background Art
[0002] When producing cigarettes, cigarette factories usually process multiple small holes on the periphery of the cigarette filter to further reduce tar and reduce harm. When smoking cigarettes, external air enters through the small holes on the filter and mixes with the smoke, diluting the smoke and achieving tar reduction and harm reduction. The processing and forming of the multiple small holes on the cigarette filter is completed through a laser drilling process. A perforated drum wheel and a laser focusing head and a cigarette pulling roller adjacent to the perforated drum wheel are set in the assembly unit. When the cigarette is transported from the periphery of the perforated drum wheel and passes through the cigarette pulling roller, the cigarette rotates around its own axis under the contact action of the cigarette pulling roller. During the rotation process, the laser focusing head completes the laser drilling of the periphery of the cigarette filter.
[0003] Since the cigarette roller contacts the cigarettes, this area is prone to the accumulation of cigarettes, smoke foam and other debris. Usually, a waste cigarette collection box is set at the bottom to collect the accumulated cigarettes and other debris in the collection box. However, when cigarettes and other debris are accumulated in the above-mentioned local space, the debris is exposed to laser for a long time, and cigarettes and other debris are prone to generate smoldering sparks. In order to avoid fire, it is usually chosen to set a smoke alarm or infrared temperature detector in the waste cigarette collection box for early warning. The actual application effects of these two methods are not ideal. For smoke alarms, on the one hand, Due to the high noise and dust concentration in the workshop, the alarm is easily ignored and falsely triggered. On the other hand, the smoke generated by the smoldering of cigarettes, cigarette foam and other debris is limited and cannot be immediately detected by the smoke alarm. After the cigarettes and other debris that continue to smolder in the waste smoke collection box are transferred to the warehouse, the safety hazard is even greater. For infrared temperature detectors, due to the influence of the temperature field of each component in the connecting unit, for example, the temperature of the cigarette filter and cigarette needs to reach 120-180 degrees Celsius when rubbing and connecting, the infrared temperature detector is also prone to false triggering.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0039] like Figure 1As shown, the embodiment of the present application provides a visual monitoring method for preventing cigarette smoldering, which is applied to the process of laser punching of cigarette filters by a rolling machine, especially for preventing cigarette smoldering during the laser punching of cigarette filters. In the past, when cigarette factories performed laser punching on cigarette filters, cigarettes, cork paper, filter rods and cigarette foam were easily accumulated at the punching drum 91, and a waste cigarette collection box was usually set up below to collect these accumulated debris. Due to the accumulation and retention of these debris, the laser irradiated the debris for a long time. These debris are all flammable materials, and cigarettes, cigarette foam and other debris are prone to produce smoldering sparks. In order to avoid fire safety accidents, it is usually chosen to set a smoke alarm or an infrared temperature detector in the waste cigarette collection box for early warning. However, in actual applications, both methods have certain disadvantages. For the method of setting an infrared temperature detector, when there is a smoldering cigarette in the waste cigarette collection box, the smoldering temperature detector will be set. The temperature is high, that is, it can be detected by the infrared temperature detector. However, there are high-temperature components and areas in the cigarette rolling and splicing unit. For example, the temperature of the cigarette filter and cigarette splicing process needs to be at 120-180 degrees Celsius. This makes it easy for the infrared temperature detector to be triggered by mistake. As for the method of setting up the smoke alarm, due to the high noise and dust concentration in the production workshop, the high concentration of dust can easily cause the smoke alarm to be triggered by mistake. The high noise can easily make the relevant staff unable to hear the alarm and ignore the alarm of the smoke alarm. In addition, the smoke generated by the smoldering phenomenon of cigarettes and other debris is limited and cannot be immediately detected by the smoke alarm. If the continuously smoldering and undetected cigarettes and other debris are transferred to the warehouse and burn with open flames, it will cause more serious safety accidents. The visual monitoring method and device for preventing cigarette smoldering of the present application are intended to eliminate the smoldering phenomenon of cigarettes generated in the laser punching process of cigarette filters and improve operational safety.
[0040] The present invention provides a method for visually monitoring cigarettes to prevent smoldering, the method comprising the following steps:
[0041] S1. Determine a designated area, where the designated area is a local area outside the perforated drum 91 and corresponding to the cigarette removing roller 94;
[0042] S2. Determine standard image information, where the standard image is the state image information of the area specified in step S1 under normal continuous working conditions;
[0043] S3, obtaining real-time image information of the area specified in step S1;
[0044] S4, comparing the real-time image information in step S3 with the standard image information in step S2. If the comparison results are consistent, it is determined that there is no debris in the designated area. If the comparison results are inconsistent, it is determined that there is debris in the designated area.
[0045] S5. When the determination result is that there is no debris in the designated area, the current working state is maintained. When the determination result is that there is debris in the designated area, the debris in the designated area is immediately cleared.
[0046] In this method, the designated area refers to the local area of the cigarette where the laser punching is performed, such as Figure 3 As shown, a punching drum 91 is provided in the cigarette-making unit, and a splicing drum 92 is located upstream of the punching drum 91, and a secondary cutting drum 93 is located downstream of the punching drum 91. The cigarettes are spliced at the splicing drum 92, and the spliced cigarettes are transported to the punching drum 91 for laser punching of the filter. The punched cigarettes are then transported to the secondary cutting drum 93. A cigarette-pulling roller 94 and a laser focusing head 95 are provided above the punching drum 91. The laser focusing head 95 can emit a laser to punch holes on the periphery of the filter. The axis of the cigarette-pulling roller 94 is parallel to the axis of the punching drum 91. The wheel 91 rotates to transport cigarettes. When the cigarettes on the periphery of the punching drum 91 move to the cigarette roller 94, the cigarette roller 94 and the outer periphery of the cigarette produce a certain amount of contact, which will cause the cigarette to rotate around its own axis. In this way, the laser focusing head 95 can complete the punching of the entire circumference of the filter. Due to the contact friction of the cigarette roller 94 on the cigarette, and the fact that debris such as cork paper, filter rods and tobacco foam are often generated in the cigarette-making unit, the debris is likely to accumulate at the cigarette roller 94. The accumulation of debris will be exposed to the laser for a long time, so the designated area is prone to smoldering.
[0047] In this method, the laser punching area of the cigarette is directly monitored. The smoldering of the cigarette is caused by the long-term exposure of the debris accumulated in the designated area to the laser. Compared with the previous method of setting up relevant early warning devices in the residual cigarette collection box for early warning, this method directly stops the smoldering at the source. When debris appears in the designated area, the debris is immediately cleared away. In this way, the debris can be effectively prevented from being exposed to the laser for a long time, and the smoldering phenomenon of cigarettes can be completely avoided.
[0048] In this method, the local area outside the perforated drum 91 and corresponding to the cigarette roller 94 is determined as the designated area, that is, the local area along the outer periphery of the perforated drum 91 and close to the cigarette roller 94. In other words, the designated area includes the area between the cigarette roller 94 and the perforated drum 91 and the areas on both sides of the cigarette roller 94 along the rotational circumference of the perforated drum 91. Laser drilling of the cigarette filter is performed in the designated area. The normal continuous working state means that the equipment continuously performs laser drilling of the cigarette filter and no debris is accumulated in the designated area. The image of the designated area in this state The information is the standard image information, which is used as a reference standard. The real-time image information is the image information status of the designated area during the operation of the equipment. The acquired real-time image information and the standard image information are compared. If the comparison results are consistent, it indicates that there is no accumulation of debris in the designated area, and the current operating status of the position is sufficient. If the comparison results are inconsistent, it indicates that there is accumulation of debris in the designated area, and the debris in the designated area must be immediately cleared to avoid the accumulated debris from being exposed to laser for a long time, completely eliminating the occurrence of cigarette smoldering.
[0049] Preferably, in step S4, when comparing the standard image information and the real-time image information, the standard image information is first segmented and calculated using a boundary algorithm, and the real-time image information is segmented and calculated using a boundary algorithm, and then the results are compared to improve the accuracy and precision of monitoring.
[0050] More preferably, step A is further included, which is: storing the standard image information in step S2 and the real-time image information in step S3 respectively. When acquiring data, the standard image information and the real-time image information are stored respectively. Step A is preferably before step S4, first storing the data and then comparing them, so as to subsequently verify the relevant data, debug the equipment, and improve the accuracy of monitoring.
[0051] More preferably, the method further comprises steps B and C:
[0052] B. After completing the debris removal in step S5, obtain the real-time image information of the designated area in step S1 and compare the real-time image information obtained in this step with the standard image information in step S2. If the comparison results are consistent, it is determined that there is no debris in the designated area. If the comparison results are inconsistent, it is determined that there is debris in the designated area.
[0053] C. When the result of the judgment is that there is no debris in the designated area, the normal continuous working state is restored. When the result of the judgment is that there is debris in the designated area, an alarm is issued and the working state is stopped, and the debris in the designated area is immediately cleared.
[0054] Under the action of step B and step C, after the debris in the designated area is cleared through step S5, the real-time image information and the standard image information are compared again to verify whether the debris in the designated area has been cleared. If it is cleared, the equipment operates normally. If the debris in the designated area is not cleared, an alarm is issued and the equipment is controlled to stop running, and then the debris in the designated area is cleared, thereby further ensuring that the debris in the designated area is completely cleared to prevent cigarette smoldering. In this embodiment, the debris removal method of step C is manual removal. Since the debris removal in step C is due to the fact that step S5 is not cleared, it is not avoided that the debris is not cleared again due to unexpected factors. A more reliable manual removal is adopted, and the debris removal is more thorough. The preferred cleaning method for step S5 is airflow blowing cleaning, which is automatically cleared with the help of the equipment to improve convenience.
[0055] In this way, two debris removal processes are performed, the first one is the equipment's 76-spray cleaning, and the second one is manual cleaning, which improves the convenience and reliability of the entire debris removal process.
[0056] In addition, the embodiment of the present application also provides a visual monitoring device for preventing cigarette smoldering, such as Figure 2-4 As shown, the device can implement the above-mentioned visual monitoring method for preventing cigarette smoldering.
[0057] The visual monitoring device for preventing cigarette smoldering includes an image acquisition module 201, an image processing module 203, a cleaning module 204 and a controller 200. The image acquisition module 201 is used to obtain standard image information of a specified area and real-time image information in the specified area. The image processing module 203 is connected to the image acquisition module 201. The image acquisition module 201 transmits the obtained standard image information and real-time image information to the image processing module 203. The image processing module 203 can compare the standard image information in the specified area with the real-time image information in the specified area. The cleaning module 204 is used to clear debris in the specified area. The cleaning module 204 is connected to the controller 200, the image processing module 203 is connected to the controller 200, and the image acquisition module 201 is connected to the controller 200.
[0058] In this embodiment, the image acquisition module 201 obtains standard image information and real-time image information in the specified area, and then transmits the obtained standard image information and real-time image information to the image processing module 203. The graphics processing module compares the standard image information and the real-time image information. If the comparison results are consistent, it indicates that there is no accumulation of debris in the specified area and the current working state can be maintained. If the comparison results are inconsistent, it indicates that there is accumulation of debris in the specified area and the controller 200 starts the cleaning module 204. The cleaning module 204 clears the debris in the specified area.
[0059] Preferably, there are two image acquisition modules 201, and the two image acquisition modules 201 are respectively located on both sides of the cigarette roller 94. In this embodiment, along the peripheral rotation direction of the perforated drum 91, the two image acquisition modules 201 are respectively located on the upstream side and the downstream side of the cigarette roller 94, and the image acquisition module 201 is farther away from the perforated drum 91 than the cigarette roller 94. In this way, both sides of the cigarette roller 94 can be monitored separately, and the monitoring is more comprehensive to ensure the thoroughness of the removal of debris in the designated area. The image acquisition module 201 includes a camera, which is set close to the designated area to capture data of the designated area. More preferably, the visual monitoring device for preventing cigarette smoldering also includes a light source 3 00, the light source 300 is set close to the designated area, and the light source 300 is used to illuminate the designated area, improve the brightness of the designated area, make the camera's shooting clearer, and monitor more accurately. In this embodiment, the number of light sources 300 corresponds to the number of image acquisition modules 201, and the number of light sources 300 is the same as the number of image acquisition modules 201. Each light source 300 is respectively set close to the corresponding image acquisition module 201, that is, the two image acquisition modules 201 are respectively located upstream and downstream of the cigarette removing roller 94, and the two light sources 300 are also respectively located upstream and downstream of the cigarette removing roller 94, so that each image acquisition module 201 has an independent light source 300 for auxiliary illumination, which is conducive to improving the accuracy of data acquisition.
[0060] More preferably, it also includes a storage module 202, which is connected to the image acquisition module 201, and the storage module 202 is also connected to the image processing module 203. The storage module 202 is used to store the standard image information of the specified area obtained by the image acquisition module 201 and the real-time image information of the specified area. After the data is stored, it is transmitted to the image processing module 203 for comparison processing.
[0061] In one example, the cleaning module 204 includes a nozzle 400 and a compressed air source. The nozzle 400 is connected to the compressed air source, and the nozzle 400 is close to the designated area. The compressed air source provides compressed gas to the nozzle 400. The nozzle 400 can spray the designated area, thereby achieving the blowing and removal of debris in the designated area.
[0062] Preferably, in a plane perpendicular to the axial direction of the perforated drum 91, the trajectory of the nozzle 400's blowing surface is arranged in an arc shape and corresponds to the outer peripheral shape of the perforated drum 91, so that the debris in the designated area can be blown away along the outer peripheral direction of the perforated drum 91. In this embodiment, the blowing direction of the nozzle 400 is parallel to the axial direction of the perforated drum 91. The nozzle 400 is located at one end of the perforated drum 91, and the blowing direction of the nozzle 400 is toward the other end of the perforated drum 91. The nozzle 400 is provided with an arc groove 401. The arc groove 402 is provided on the nozzle 400. 01 is connected to the compressed air source through the nozzle 400, so that the air flow is sprayed to the designated area through the arc groove 401. The arc groove 401 is arc-shaped and, when viewed along the axial direction of the punching drum 91, the arc groove 401 is located outside the outer periphery of the punching drum 91, and the axial projection of the arc groove 401 and the cigarette removing roller 94 partially overlap. The arc groove 401 is symmetrically arranged relative to the line connecting the axis of the cigarette removing roller 94 and the axis of the punching drum 91. In this way, the axial spraying can be performed on the designated area more evenly and effectively, which is more conducive to the separation of debris from the designated area.
[0063] More preferably, a gas pipeline is provided between the nozzle 400 and the compressed gas source, one end of the gas pipeline is connected to the nozzle 400, and the other end of the gas pipeline is connected to the compressed gas source. The compressed gas source provides compressed gas to the nozzle 400 through the gas pipeline. A solenoid valve is provided on the gas pipeline, and the solenoid valve is connected to the controller 200. The solenoid valve is controlled by the controller 200 to realize the on and off of the gas pipeline, thereby realizing whether the nozzle 400 sprays the designated area.
[0064] More preferably, the visual monitoring device for preventing cigarette smoldering also includes an alarm module 205, which is connected to the controller 200. The alarm module 205 is used to issue an alarm that there are debris in the designated area.

At this time, the controller 200 controls the entire equipment to shut down and manually remove the debris in the designated area. The alarm module 205 may include a warning light and a buzzer to remind relevant staff through visual and auditory perception to prevent the alarm from being ignored by the staff.
