Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging, and in particular to a cigarette pack coding device. Background Technology

[0002] Currently, inkjet coding is a crucial step in the tobacco industry's production process. Traditional inkjet coding methods for cigarette cartons are often rigid, using fixed-position coding. This method is prone to deviations in coding position and content, affecting the overall aesthetics and legibility of the product. For example, the ultraviolet laser marking machine for cigarette cartons disclosed in Chinese Patent Publication No. CN214984262U includes a base, with support frames fixedly connected to the left and right sides of the top of the base. A fixing bolt is fixedly connected to the top of each support frame, and a conveyor belt is fixedly connected to the rear of the fixing bolt. A half-gear turntable is rotatably connected inside the conveyor belt. A base is fixedly connected to the top of the base, and a bracket is fixedly connected to the top of the base. A movable groove is opened at the center of the top of the bracket, and a detector is rotatably connected inside the movable groove. A spray nozzle is fixedly connected to the bottom of the detector. The half-gear turntable, through a half-gear structure and chain meshing transmission, achieves intermittent transmission. Each group of cigarette cartons is transported to the same position, and then a limiting plate limits the movement of the cigarette cartons, ensuring that each group of cigarette cartons arrives at the marking area in the same posture, thereby improving the marking accuracy.

[0003] Existing automated cigarette bar coding devices still have shortcomings in recognizing the position, posture, and angle of cigarette bars. Since cigarette bars may shift or tilt during transport due to various reasons, if the coding device cannot accurately identify these changes, it will lead to problems such as inaccurate coding position and unclear content. Utility Model Content

[0004] Therefore, in response to the above problems, this utility model proposes a cigarette coding device, which solves the technical problem that existing coding devices cannot accurately identify changes in the position, posture, and angle of cigarette packs, and cannot achieve accurate and clear coding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cigarette bar coding device, comprising a frame and a conveyor belt for conveying cigarette bars mounted on the frame, and a coding mechanism for coding.

[0006] The frame is provided with a transverse shift seat that moves laterally along the conveying direction of the conveying device, and the frame is provided with a transverse shift drive mechanism for driving the transverse shift seat to move laterally.

[0007] The transverse sliding seat is provided with a lifting seat that can be raised and lowered, and the transverse sliding seat is provided with a lifting drive mechanism for driving the lifting seat.

[0008] A rotating seat is rotatably provided on the lifting seat, and a rotation drive mechanism for driving the rotating seat to rotate is provided on the lifting seat.

[0009] The rotating base is equipped with a camera for identifying cigarette packs.

[0010] Furthermore, the transverse drive mechanism includes a transverse lead screw connected to the output shaft of the transverse drive mechanism and a transverse nut sleeved on the transverse lead screw and fixedly connected to the transverse seat. The transverse lead screw is arranged along the conveying direction of the conveying device. The transverse drive mechanism drives the transverse lead screw to rotate, thereby causing the transverse nut and the transverse seat to move laterally.

[0011] Furthermore, the lifting drive mechanism includes a lifting screw connected to the output shaft of the lifting drive mechanism and a lifting nut sleeved on the lifting screw and fixedly connected to the lifting seat. The lifting screw is arranged in a vertical direction and is driven to rotate by the lifting drive mechanism, thereby driving the lifting nut and the lifting seat to move up and down.

[0012] Furthermore, the rotation drive mechanism is a rotary motor, which drives the rotating base to rotate.

[0013] Furthermore, the rotating base is provided with a mounting slot, the camera is installed in the mounting slot, and a transparent protective cover is provided at the opening of the mounting slot to protect the camera from interference from external dust and debris.

[0014] Furthermore, it also includes a control system, which is electrically connected to the transverse drive mechanism, the lifting drive mechanism, the rotation drive mechanism and the coding mechanism, and is used to adjust the coding position and content according to the recognition result of the camera.

[0015] Furthermore, the control system includes an image processing module for analyzing the images captured by the camera, identifying the color, type, specifications, and orientation of the cigarette packs, and generating corresponding inkjet printing parameters.

[0016] Furthermore, the transverse sliding seat, lifting seat, and rotating seat are all made of high-strength aluminum alloy and the surface is anodized to improve corrosion resistance and structural stability.

[0017] Furthermore, the conveyor belt surface is provided with anti-slip texture and side guards are provided on both sides to prevent the cigarette packs from shifting or slipping during the conveying process.

[0018] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0019] 1. The cigarette coding device, through the arrangement of a horizontal sliding seat, a lifting seat, and a rotating seat, enables flexible adjustment of the coding mechanism in three-dimensional space. This design ensures that the coding mechanism is accurately aligned with the cigarette packs, achieving precise coding regardless of the position, posture, or angle of the cigarettes on the conveyor belt. Simultaneously, the camera can identify cigarette information in real time, including but not limited to the cigarette's position, posture, angle, color, type, and specifications, providing accurate data support for subsequent coding operations.

[0020] 2. The transverse drive mechanism employs a combination of a transverse drive mechanism, a transverse lead screw, and a transverse nut, achieving precise and smooth movement of the transverse seat. This design is not only simple in structure and easy to maintain, but also ensures the stability and accuracy of the transverse seat during movement. By adjusting the rotation speed and direction of the transverse drive mechanism, the moving speed and direction of the transverse seat can be flexibly controlled, thus adapting to the needs of different specifications and positions of cigarette coding.

[0021] 3. The lifting drive mechanism employs a combination of a lifting drive mechanism, a lifting screw, and a lifting nut, achieving precise lifting of the lifting seat. This design allows the coding mechanism to flexibly adjust its height in the vertical direction to accommodate cigarette packs of different sizes and positions. Simultaneously, the stability and accuracy of the lifting drive mechanism ensure the smoothness and reliability of the lifting seat during the lifting process.

[0022] 4. The rotary drive mechanism employs a combination of a rotary drive mechanism, a driving gear, and a driven gear to achieve precise rotation of the rotating base. This design allows the coding mechanism to flexibly adjust its angle in the horizontal plane to adapt to different postures and angles of the cigarette packs. By adjusting the rotation speed and direction of the rotary drive mechanism, the rotation speed and direction of the rotating base can be precisely controlled, thereby ensuring that the coding mechanism can accurately align with the cigarette packs for coding.

[0023] 5. By incorporating a mounting slot and a transparent protective cover on the rotating base, the camera can be protected from external dust and debris. This design not only improves the camera's stability and lifespan but also ensures that the camera can clearly capture image information of the cigarette pack. Furthermore, the transparent protective cover does not affect the camera's normal operation or recognition accuracy.

[0024] 6. The control system enables comprehensive control and management of the coding device. Through electrical connections with each drive mechanism and coding mechanism, the control system can receive the recognition results from the camera in real time and automatically adjust the coding position and content based on the recognition results. This design not only improves the automation and intelligence level of the coding device but also ensures the accuracy of the coding position and content.

[0025] 7. The image processing module enables in-depth analysis and processing of images captured by the camera. By identifying information such as the color, type, size, and orientation of the cigarette packs, the image processing module can generate corresponding coding parameters, providing accurate data support for subsequent coding operations. This design not only improves the recognition accuracy and coding quality of the coding device but also adapts to the coding needs of different types and sizes of cigarette packs.

[0026] 8. The use of high-strength aluminum alloy with anodizing treatment significantly improves the corrosion resistance and structural stability of the transverse, lifting, and rotating seats. This design not only extends the service life of the coding device but also ensures the normal operation of each component in harsh environments. Furthermore, the high-strength aluminum alloy material is lightweight and possesses excellent mechanical properties, making the overall coding device more portable and durable.

[0027] 9. The conveyor belt surface features anti-slip textures and edge guards, effectively preventing cigarette packs from shifting or slipping during transport. This design not only improves the stability and reliability of cigarette pack transport but also ensures accurate identification and coding by the inkjet printer. Furthermore, the anti-slip textures and edge guards accommodate cigarette packs of different sizes and weights, enhancing the applicability and flexibility of the inkjet printer.
