Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and in particular to a device for detecting disorderly cigarettes. Background Technology

[0002] In the tobacco product manufacturing process, many cigarette packaging machines connect unloading machines, cigarette conveying channels, and high-speed packaging machines to complete the cigarette packaging process. As a key hub connecting the unloading machine and the high-speed packaging machine, the cigarette conveying channel undertakes the important task of orderly and stable transportation of cigarettes to the tobacco warehouse, and its operating status directly affects the stability of cigarette supply from the high-speed packaging machine.

[0003] However, due to the limitations of the existing unloading machine's mechanical structure, the turning action of the tray is prone to generating random smoke under high-speed production conditions. This random smoke then follows the orderly arranged cigarettes through the cigarette conveying channel into the cigarette storage of the high-speed packaging machine, causing the cigarettes to block the lower cigarette channel. This results in the high-speed packaging machine experiencing unstable cigarette supply, frequent shutdowns, or even serious malfunctions, affecting production efficiency. At the same time, the blockage also generates a large amount of waste smoke. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a disordered smoke detection device for detecting disordered smoke in the cigarette conveying channel 1. Disordered smoke includes horizontal smoke 101 located at the cigarette mouthpiece end (e.g., ...). Figure 5 (as shown) and the horizontal cigarette 102 (as shown) mixed in with the cigarette 10. Figure 6 As shown, the detection device includes: a detection imager 2, a smoke outlet 3, a protective door 4, an electric push rod 5, and a control unit 6.

[0036] Specifically, the imaging device 2 is located outside the cigarette conveying channel 1; a transparent area (i.e., ...) is provided on the vertical side wall of the cigarette conveying channel 1. Figure 3 and Figure 4 The area enclosed by the dashed frame S, the mouthpiece end of the cigarette 10 in the cigarette conveying channel 1 and the detection end of the detection image instrument 2 both face the transparent area. The detection image instrument 2 is used to detect the arrangement of the cigarettes 10 in the transparent area.

[0037] The smoke outlet 3 is along the conveying direction of the cigarette stick 10 (e.g., Figure 1 and Figure 2 The X direction shown is located downstream of the transparent area.

[0038] The protective door 4 covers the smoke outlet 3 and is hinged to the cigarette conveying channel 1.

[0039] The electric push rod 5 is connected to the guard plate door 4 and is used to drive the guard plate door 4 to rotate, so that the smoke outlet 3 opens or closes. For example, the electric push rod 5 is a magnetic electric push rod, which is magnetically connected to the guard plate door 4 through a magnetic component.

[0040] The control unit 6 is electrically connected to the detection image device 2, and is used to receive the image data detected by the detection image device 2, and to determine whether there is horizontal smoke located at the end of the cigarette mouthpiece and horizontal smoke mixed in with the cigarette 10 based on the image data; when the detected image is like Figure 3 When the smoke is located at the mouthpiece end, the control unit 6 issues a first alarm and, after a preset time extension, controls the electric push rod 5 to open the guard plate door 4, allowing the smoke 101 at the mouthpiece end to fall through the smoke outlet 3 to the outside of the cigarette conveying channel 1. When smoke is detected mixed in with the cigarette 10, the control unit 6 issues a second alarm, reminding the operator to clean the smoke 102 mixed in with the cigarette 10.

[0041] It should be noted that the purpose of extending the preset time is to open the guard plate door 4 only after the horizontal cigarette 101 at the mouthpiece end has moved to the smoke outlet 3. This ensures that the horizontal cigarette 101 at the mouthpiece end can fall smoothly outside the cigarette conveying channel 1 without affecting the normal conveying of other orderly arranged cigarettes 10. The preset time can be set according to the actual production situation, for example, based on the distance between the area that the detection image instrument 2 can detect and the guard plate door 4, as well as the conveying speed of the cigarette conveying channel.

[0042] This application uses an image detection device 2 to detect the arrangement of cigarettes 10 within the cigarette conveying channel 2. The control unit 6 receives the image data from the image detection device 2 and accurately determines the presence of disordered cigarettes based on the data. Different alarms are then issued for different types of disordered cigarettes, and the electric push rod 5 is controlled to open the guard plate door 4 to expel the horizontal smoke 101 located at the cigarette mouthpiece end. Using this disordered cigarette detection device, disordered cigarettes can be prevented from entering the packaging process, avoiding machine stoppages due to unstable cigarette supply, thereby improving production efficiency, ensuring a stable and orderly production process, and reducing the generation of a large amount of waste smoke.

[0043] In some implementations, reference Figure 7 The control unit 6 includes a detection image processing module 61 electrically connected to the detection imager 2. The detection image processing module 61 is used to receive and process the image data detected by the detection imager 1. By setting the detection image processing module 61, this application can receive the raw image data detected by the detection imager 2 and perform preliminary preprocessing on this raw data, such as noise reduction and contrast enhancement, to improve the accuracy of subsequent judgments.

[0044] In some implementations, reference Figure 7 The control unit 6 also includes a judgment module 62 electrically connected to the detection image processing module 61. The judgment module 62 receives the image data processed by the detection image processing module 61 and determines whether there are horizontal smoke 101 at the mouthpiece end and horizontal smoke 102 mixed in with the cigarette 10 based on the processed image data. By setting the judgment module 62, this application can analyze the image data through its internal preset algorithm and judgment criteria to determine whether there are horizontal smoke 101 at the mouthpiece end and horizontal smoke 102 mixed in with the cigarette 10. For example, the YOLO (You Only Look Once, a real-time object detection algorithm based on deep learning) deep learning visual detection model is used to train the disordered smoke dataset to obtain a disordered smoke visual detection algorithm. The disordered smoke visual detection algorithm analyzes the arrangement direction and posture of the cigarettes 10. When a horizontally arranged cigarette 10 is detected at the mouthpiece end, it is determined to be a horizontal smoke 101 at the mouthpiece end; when an abnormally horizontally arranged cigarette 10 is detected among the cigarettes 10, it is determined to be a horizontal smoke 102 mixed in with the cigarette 10.

[0045] It should be noted that in order to obtain the visual detection algorithm for disordered smoke, it is necessary to collect image data covering various disordered smoke situations, and to label and classify the image data to form a disordered smoke dataset. The disordered smoke dataset is then substituted into the YOLO deep learning visual detection model for training, thereby obtaining the visual detection algorithm for disordered smoke used in this application.

[0046] In some implementations, reference Figure 7 The control unit 6 also includes an alarm device 63, which includes a first alarm 631 and a second alarm 632. The first alarm 631 is used to issue a first alarm, and the second alarm 632 is used to issue a second alarm. Exemplarily, the alarm device 63 is a Bluetooth alarm speaker. In this embodiment, the alarm device 63 is preferably a Bluetooth alarm speaker, which facilitates wireless connection and remote alarm functions with other devices. This type of alarm speaker has advantages such as long transmission distance and clear sound, effectively ensuring that operators receive alarm information in a timely manner.

[0047] Optionally, such as Figure 5 As shown, a disordered smoke detection device also includes a display 7, electrically connected to the control unit 6. The display receives and displays image data processed by the detection image processing module 61, and displays the position of the disordered smoke analyzed by the judgment module 62 within the image data. By setting up the display 7, this application allows operators to intuitively observe the arrangement of cigarettes 10 in the cigarette conveying channel 1. When disordered smoke occurs, it can also quickly locate the position of the disordered smoke, thereby timely removing the disordered smoke and avoiding downtime of equipment such as packaging machines.

[0048] Optionally, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device for detecting disorderly smoke also includes a waste smoke collection box 8, which is located below the smoke outlet 3 and is used to collect cigarettes 10 that fall from the smoke outlet 3. By setting up the waste smoke collection box 8, this application facilitates the unified treatment of waste smoke in the future, and avoids waste smoke from scattering in the production environment, polluting the production environment and affecting product quality.

[0049] Specifically, after the cigarette production equipment is started, the detection image device 2 begins to capture images of the cigarettes 10 within the transparent area of ​​the cigarette conveying channel 1, obtaining image data of the arrangement of the cigarettes 10, and transmits this image data to the detection image processing module 61 of the control unit 6. The detection image processing module 61 preprocesses the received image data and then transmits the preprocessed image data to the judgment module 62. The judgment module 62 then uses the aforementioned disordered smoke visual detection algorithm to analyze the preprocessed image data, determining whether there are horizontal smoke 101 located at the cigarette mouthpiece end or horizontal smoke 102 mixed within the cigarettes 10, and marking the location of the disordered smoke by selecting different colored checkboxes on the display 7 according to the different types of disordered smoke. If a cross smoke 101 is detected at the cigarette holder end, the judgment module 62 transmits the judgment result to the control unit 6. After a preset time, the control unit 6 controls the electric push rod 5 to open the guard plate door 4, allowing the cross smoke 101 at the cigarette holder end to be discharged from the smoke outlet 3 and fall into the waste smoke collection box 8 under its own gravity. At the same time, the control unit 6 controls the first alarm 631 to sound the first alarm, reminding the operator of the presence of cross smoke 101 at the cigarette holder end. If a cross smoke 102 is detected mixed in with the cigarette stick 10, the judgment module 62 transmits the judgment result to the control unit 6. The control unit 6 controls the second alarm 632 to sound the second alarm, notifying the operator of the presence of cross smoke 102 mixed in with the cigarette stick 10. The operator must arrive at the scene in time and manually remove the cross smoke according to the location of the cross smoke displayed on the display 7. If both the horizontal smoke 101 located at the mouthpiece end and the horizontal smoke 102 mixed inside the cigarette stick 10 are detected simultaneously, the judgment module 62 transmits the judgment result to the control unit 6. The control unit 6 controls the electric push rod 5 to move and open the guard plate door 4 (e.g. Figure 4 The position of the guard plate door 4 shown in the diagram allows the horizontal smoke 101 located at the cigarette holder end to be discharged from the smoke outlet 3 and fall into the waste smoke collection box 8 under its own weight. At the same time, the second alarm 632 is controlled to sound a second alarm, notifying the operator that there is horizontal smoke 102 mixed in with the cigarette stick 10. The operator needs to rush to the scene in time and manually remove it according to the location of the disordered smoke displayed on the monitor 7. After the horizontal smoke 101 at the cigarette holder end is dealt with, the control unit 6 controls the electric push rod 5 to move in the opposite direction, pulling the guard plate door 4 back to its original position (as shown in the diagram). Figure 3 (As shown in the diagram, the position of the protective door 4) closes the smoke outlet 3, allowing the cigarette conveying channel 1 to return to normal conveying status.

[0050] Optionally, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the cigarette conveying channel 1 includes a horizontal conveying channel 11 and a vertical conveying channel 12. The vertical conveying channel 12 is located downstream of the horizontal conveying channel 11 and is used to convey the cigarettes 10 output from the horizontal conveying channel 11 from bottom to top. A transparent area is provided on the horizontal conveying channel 11. The transparent area on the horizontal conveying channel 11 facilitates the detection of the cigarette arrangement by the detection image device 2. Through the transparent area, the detection image device 2 can clearly capture the state of the cigarettes 10, providing accurate data support for subsequent judgment of disordered cigarettes.

[0051] In some implementations, reference Figure 1 and Figure 2 A disorderly cigarette detection device also includes a universal bracket 9, which is located on one side of the transparent area of ​​the cigarette conveying channel 1. A detection imager 2 is mounted on the universal bracket 9, and the lens direction of the detection imager 2 can be adjusted. By setting up the universal bracket 9, the operator can flexibly adjust the universal bracket 9 according to actual detection needs, thereby changing the lens direction of the detection imager 2. This ensures that the arrangement of cigarettes 10 within the transparent area can be detected comprehensively and accurately. Therefore, the disorderly cigarette detection device can adapt to cigarette conveying channels 1 of different specifications and layouts, improving the versatility and installation flexibility of the device, and reducing installation difficulty and cost.
