Description

Technical Field

[0001] This application relates to the field of tobacco product manufacturing technology, and in particular to an information verification method, apparatus, computer equipment, storage medium, and computer program product for a cigarette pack packaging box. Background Technology

[0002] With changes in production models and the development of the tobacco industry, the previous single production has transformed into personalized production with multiple specifications and brands, which has led to increasingly higher technical requirements for cigarette pack packaging.

[0003] In existing technologies, cigarette packing box equipment is used to package cigarettes into boxes. One packing box machine can handle multiple brands, efficiently automating the entire process of collecting, stacking, packing, and sealing cigarette packs. However, while one packing box machine handling multiple brands significantly improves cigarette packing efficiency, it also introduces the risk of mixing brands and missing packs. Specifically, mechanical defects or human error can lead to brand A cigarette packs being mixed into brand B boxes, or boxes being sealed before they are full. Common methods for detecting missing packs, such as weighing, have too much error and make it difficult to accurately verify the internal information of the cigarette packing box equipment.

[0004] Therefore, a solution is needed to verify the information of cigarette packing boxes with multiple specifications and brands, thereby improving the accuracy of the packing boxes. Summary of the Invention

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] The information verification method for cigarette pack packaging equipment provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 monitors cigarette packing box equipment 104 via the network. Terminal 102 acquires the brand information of the brands to be packaged in the stack and the brand information of the silo in the cigarette packing box equipment 104, and pushes the stack and silo brand information to different workstations of the cigarette packing box equipment. Terminal 102 uses image recognition to verify the brand information of the stack, the box blank, and the cigarette packing station. Terminal 102 acquires the verification images of the cigarette packing box equipment. If no mismatched brands are found in the verification images, a visual inspection of missing cigarette packs is performed on the cigarette packing box equipment, acquiring a missing cigarette pack inspection image. If no missing cigarette pack information is found in the missing cigarette pack inspection image acquired by terminal 102, the information verification of the cigarette packing box equipment 104 is deemed successful.

[0063] In one embodiment, such as Figure 2 As shown, an information verification method for cigarette packing box equipment is provided, which is applied to... Figure 1 Taking terminal 102 as an example, the explanation includes the following steps:

[0064] S100: Obtain the stacking brand information and silo brand information of the brand to be packaged.

[0065] The "brand to be packaged" refers to the brand that the cigarette pack packaging equipment needs to package at a certain time. "Stacking" refers to the accumulation of items, or the regular arrangement of items to form a stack. In this application, stacking refers to the regular stacking of cigarette packs; when the stack reaches a predetermined number of layers, the stack is formed. A silo is a storage device; in this application, the silo is used to store unformed box blanks. The "stacking brand information" and "silo brand information" refer to the brand information of the cigarette packs constituting the stack and the brand information of the box blanks in the silo, respectively.

[0066] Specifically, after the cigarette packs are stacked to a predetermined number of layers and the stack is formed, the terminal 102 obtains the stacking brand information of the brand to be packaged and the silo brand information, which is beneficial for selecting a specific brand information for information verification when there are cigarette pack packaging box equipment with multiple specifications and brands.

[0067] The S200 pushes stacking brand information and silo brand information to different workstations of the cigarette packing box equipment.

[0068] In this context, "push" refers to the act of a message sender transmitting information to a recipient. In this application, the message sender refers to terminal 102, and the message recipients refer to different workstations on the cigarette packing box equipment. The transmitted messages include stacking brand information and silo brand information.

[0069] Specifically, after obtaining the stacking brand information and silo brand information of the brand to be packaged, the terminal 102 pushes the obtained stacking brand information and silo brand information of the brand to be packaged to different workstations of the cigarette pack packaging equipment, so as to facilitate the subsequent verification of the brand information pushed to different workstations.

[0070] Furthermore, the workstations of the cigarette packing box equipment include, but are not limited to: mold box workstation, cigarette packing and pushing workstation, robotic arm gripping workstation, box blank forming workstation, tape workstation, and export workstation.

[0071] The S300 uses image recognition to verify the brand information of stacking, box blanks, and cigarette packing stations, and obtains the verification images of the cigarette pack packaging boxes.

[0072] The image recognition method involves taking a picture using an image recognition device and then visually recognizing the image. In this application, the verification images include verification images of stacking brands, verification images of box blank brands, and verification images of brand information at the cigarette-pushing station.

[0073] Specifically, terminal 102 acquires the stacking brand verification image, the box blank brand verification image, and the brand information verification image of the cigarette pushing station, which are generated by triggering the camera to take pictures respectively. It uses image recognition to verify the verification images acquired by the terminal and determines whether the stacking brand, box blank brand, and cigarette pushing station brand information match.

[0074] Optional devices for image recognition include, but are not limited to, cameras, video cameras, and other devices with photographic capabilities.

[0075] S400, if no mismatched brand information is found in the calibration image, a visual inspection of missing cigarette packs is performed on the cigarette pack packaging box to obtain a missing cigarette pack inspection image of the cigarette pack packaging box.

[0076] Among them, mismixed brand information refers to cigarette packs of brand A being packed into cigarette boxes of brand B; missing packs refer to cigarette boxes being missing corresponding packs due to machine detection defects or human factors during stacking, commonly including missing 1 pack, 5 packs, 25 packs, or even an empty box.

[0077] Specifically, if no mismatched brand information is found after verifying the stacking brand verification image, the box blank brand verification image, and the cigarette packing station brand verification image, the cigarette pack packaging box can be re-inspected for missing cigarette packs. The terminal 102 will obtain the missing cigarette pack re-inspection image of the cigarette pack packaging box and use visual detection based on the missing cigarette pack re-inspection image to determine whether there is a missing cigarette pack in the cigarette pack packaging box.

[0078] S500: If no missing strip information is found in the missing strip review image, the information verification of the cigarette packing box equipment is deemed to have passed.

[0079] Specifically, if terminal 102 verifies the stacked brand verification image, the box blank brand verification image, and the cigarette packing station brand verification image and finds no mixed or incorrect brand information, and verifies the missing strip re-check image and finds no missing strip information, then the information verification of the cigarette packing box equipment can be considered to have passed, and the brand information contained in the cigarette packing box is correct.

[0080] The aforementioned information verification method for cigarette packing box equipment obtains the brand information of the stacking and silo of the brand to be packaged. For packaging boxes with multiple specifications and brands, it selects a specific brand for verification, achieving a one-to-many detection effect. The stacking and silo brand information are then pushed to each workstation of the cigarette packing box equipment to confirm which brand information needs to be selected for the next operation. After the push, image recognition is used to perform secondary verification of the brand information at the stacking, box blank, and cigarette feeding stations, obtaining verification images of the cigarette packing boxes. If no mismatched brands are found in the verification images, a visual inspection for missing cigarette packs is performed, obtaining a missing cigarette pack inspection image. If no missing cigarette packs are found in the inspection image, the information verification of the cigarette packing box is considered successful, resulting in a cigarette packing box with correct brand information. The method of transmitting brand information between workstations during the cigarette pack packaging process and using acquired images to verify brand information reduces the risk of mixed brands and missing packs in the cigarette pack packaging equipment, thereby improving the accuracy of cigarette pack packaging.

[0081] In one embodiment, such as Figure 3 As shown, obtaining the stacking brand information and silo brand information of the brand to be packaged includes:

[0082] S120, obtain the stacking brand information of the brand to be packaged.

[0083] S140: Match the stacking brand information of the brand to be packaged with the silo brand information to obtain the silo brand information of the brand to be packaged.

[0084] Specifically, the workstations within the cigarette pack packaging equipment include information on multiple brands. After the brand to be packaged is manually set, the stacking brand information of the brand to be packaged is obtained. The terminal 102 further obtains the designated stacking brand information of the brand to be packaged from the cigarette pack packaging equipment. The stacking brand information of the brand to be packaged is matched with multiple silo brand information, and the silo brand information that matches the stacking brand information of the brand to be packaged is selected as the silo brand information of the brand to be packaged.

[0085] In this embodiment, by specifying the stacking brand information for the cigarette packing box equipment, and then selecting the matching silo brand information from the silo brands, it is possible to achieve the technical effect of packaging multiple specifications and brands of cigarette packs with a single cigarette packing box equipment.

[0086] In one embodiment, such as Figure 4 As shown, S200 includes:

[0087] S220 pushes the stacking brand information of the brand to be packaged to the mold station;

[0088] Specifically, when the transfer robot receives the signal that the stack is full of smoke and moves to the stacking position to push the stack into the mold box, the terminal 102 pushes the stacking brand information of the brand to be packaged to the mold box station.

[0089] S240: When the stacked mold box is transported to the box-pushing station and the robotic arm grabs the box blank, the material hopper brand information of the brand to be packaged is pushed to the robotic arm grab station.

[0090] In this application, the stacking mold box refers to the object formed after the transfer robot pushes the stack into the mold box. Its interior is a stack of cigarette sticks, and its outer packaging is the mold box.

[0091] Specifically, when the stacked mold box is transported to the box-pushing station, and the robotic gripper confirms the gripping path and grips the box blank by obtaining the hopper brand information that matches the stacked brand information, the terminal 102 pushes the hopper brand information of the brand to be packaged to the robotic gripper at the robotic gripper station.

[0092] S260: When the box blank is formed, the brand information of the robotic arm gripper of the brand to be packaged is pushed to the box blank forming station.

[0093] Specifically, when the robotic arm finishes placing the box and the box blank is formed, the terminal 102 pushes the brand information of the robotic arm gripper station of the brand to be packaged to the box blank forming station.

[0094] In this embodiment, by pushing the brand information of the stacking and the brand information of the silo to different workstations of the cigarette packing box equipment, the effect of information transmission can be achieved, it can be confirmed which brand information needs to be selected for a step operation, and preparations can be made for the subsequent information verification.

[0095] In one embodiment, such as Figure 5 As shown, the information verification method for cigarette pack packaging equipment also includes:

[0096] S280, before the smoke is pushed into the box, the brand information received by the stacking mold at the smoke pushing station is checked against the brand information received by the box blank forming station.

[0097] Specifically, before the cigarette packing and pushing station, terminal 102 checks the brand information received from the stacking mold at the cigarette packing and pushing station against the brand information received from the box blank forming station. If the brand information matches during the check, the cigarette pack packaging box is controlled to perform the cigarette packing and pushing action; if the brand information does not match during the check, the cigarette pack packaging box is controlled to stop and alarm, and manual intervention is notified to handle the box blank, and the robotic arm is driven to restart the box blank grabbing process.

[0098] In this embodiment, the brand information received by the stacking mold at the cigarette packing station and the brand information received by the box blank forming station are checked before the cigarette packing is pushed into the box. This ensures that the brand information of the box blank and the stacking mold are consistent when the cigarette pack is pushed into the box, thereby improving the accuracy of the cigarette pack packaging box.

[0099] In one embodiment, such as Figure 6 As shown, S300 includes:

[0100] S320, if the brand information received by the stacking mold box at the cigarette box pushing station and the box blank forming station passes the verification, then the stacking image inside the stacking mold box and the outer packaging image of the stacking mold box are obtained. The stacking brand is verified based on the stacking image inside the stacking mold box and the outer packaging image of the stacking mold box. The terminal 102 obtains the stacking brand verification image of the cigarette pack packaging box.

[0101] Specifically, after the brand information received at the cigarette packing station and the box blank forming station is verified, and the cigarette pack in the mold arrives at the cigarette packing station, terminal 102 obtains the stacking image inside the stacking mold and the outer packaging image of the stacking mold through image recognition. It then verifies the stacking image inside the stacking mold and the outer packaging image to determine if the brand information contained in the stacking image inside the stacking mold and the brand information contained in the outer packaging image are consistent. If the information matches, it waits for the box blank to be formed; if the information does not match, it controls the cigarette pack packaging box to alarm and stop, causing the cigarette pack to be automatically removed or manually processed.

[0102] S340, if the brand verification image of the stacking is normal, then obtain the brand image of the silo and the image of the box blank forming station, perform box blank brand verification based on the brand image of the silo and the image of the box blank forming station, and obtain the brand verification image of the cigarette pack box blank.

[0103] Specifically, after the brand information verification of the stacking image inside the stacking mold and the image of the outer packaging of the stacking mold is passed, and the robotic arm reaches above the box blank grasping position, the terminal 102 obtains the brand image of the hopper and the box blank forming station image through image recognition. It then verifies the brand information contained in the hopper brand image and the box blank forming station image to determine if they are consistent. If the information matches, the terminal 102 controls the robotic arm to grasp the box blank; if the information does not match, it notifies a human to handle the incorrect box blank and controls the robotic arm to re-grab the box blank.

[0104] S360, if the brand calibration image of the box blank is normal, then obtain the stacking mold image of the cigarette packing station and the box blank forming station image. Based on the stacking mold image of the cigarette packing station and the box blank forming station image, perform a second calibration of the cigarette packing station and obtain the second calibration image of the cigarette packing station of the cigarette packing box.

[0105] Specifically, after the brand image of the silo and the image of the box blank forming station have passed the verification and the box blank has been formed, the terminal 102 obtains the stacking mold image of the box-pushing station and the box blank forming station image through image recognition. It then verifies these images to determine if the brand information contained in the stacking mold image and the box blank forming station image are consistent. If the information is consistent, and the verification of the brand information received from the stacking mold image and the box blank forming station before box-pushing is passed, the terminal 102 controls the box-pushing action. If the information is inconsistent, it notifies the operator to handle the incorrect box blank and controls the robotic arm to re-grab the box blank.

[0106] In this embodiment, the verification images of the cigarette packing box are obtained by verifying the brand information of the stacking, the box blank, and the cigarette packing station. This is done through image recognition, which improves the efficiency and accuracy of information verification by the cigarette packing box equipment.

[0107] In one embodiment, if no mismatched brand information is found in the calibration image, a visual inspection of missing cigarette packs is performed on the cigarette pack packaging box, and the missing cigarette pack inspection image of the cigarette pack packaging box is obtained by:

[0108] If the image being checked does not contain any mismatched label information, then obtain the rear image and the front image of the cigarette packing box; perform a visual inspection of missing cigarette packs based on the rear and front images of the cigarette packing box, and obtain the missing cigarette packing box inspection image.

[0109] Specifically, when the packing machine pusher pushes the stacking molded box into the formed box blank and the pusher retracts to a certain phase, the image acquisition device receiving terminal 102 receives a trigger signal and enters the shooting state. When the corresponding infrared light source is also lit, terminal 102 acquires the infrared image of the cigarette packing machine's cigarette packing station. Terminal 102 uses image recognition to determine whether there are missing bars in the infrared image. If there are missing bars, it activates the alarm and forcibly stops the packing machine, waiting for the operator to handle it. If a rejection device is installed, it can also be notified to reject the missing bars. Finally, server 104 saves the image of the missing bar inspection of the cigarette packing machine and names the image with the shooting time.

[0110] Optionally, the devices for acquiring images include, but are not limited to, cameras, video cameras, and other devices with photographic capabilities.

[0111] In practical applications, this application utilizes a visual cigarette box missing strip inspection system to acquire images of missing strips on cigarette packing boxes. This system includes: a first infrared CCD (charge-coupled device) industrial camera, a second infrared CCD industrial camera, a third CCD industrial camera, and an infrared illumination source. The right and left infrared CCD industrial cameras have gigabit Ethernet high-speed interfaces, providing excellent infrared sensitivity and capable of acquiring 120 frames per second of high-quality infrared images with a resolution of 640*480. The rear CCD industrial camera is a high-resolution gigabit Ethernet camera, capable of acquiring 30 frames per second of high-quality color images with a resolution of 1296×966. It is installed in the carton tray and box forming area, without a light source, and operates in continuous software trigger mode and automatic gain control mode, allowing simultaneous viewing of the stacked carton shapes and the formed cartons. The infrared illumination source system consists of multiple infrared LED (light-emitting diode) light sources, which serve the left and right CCD cameras and illuminate from both sides of the smoke box.

[0112] Specifically, under infrared illumination, first and second infrared CCD industrial cameras capture images of the front and rear of the cigarette box, while a third CCD industrial camera captures a snapshot of each cigarette blank formed at the blank forming station. During operation, the infrared illumination source is in strobe mode to effectively eliminate shadows on the cigarette packing box, ensuring uniform imaging.

[0113] Furthermore, with the infrared illumination source in strobe mode, the terminal 102 receives the front and rear images of the cigarette packing box, as well as the image of each box blank formed at the box blank forming station, and analyzes them separately based on the received front and rear images of the cigarette packing box and the image of each box blank formed at the box blank forming station.

[0114] In this embodiment, the terminal 102 receives and analyzes images and performs visual inspection of missing cigarette packs, which can achieve high efficiency in missing cigarette pack detection and reduce the missing cigarette pack rate in the cigarette packing box after final packaging.

[0115] In another embodiment, the method for detecting missing strips in the visual smoke box further includes:

[0116] After the terminal 102 detects the missing strip review image information, it converts the bad smoke message output when the image is found to be abnormal and mismatched into an audible alarm signal, and at the same time sends a signal to stop the packaging machine from working, waiting for the operator to handle it.

[0117] The step of converting the output bad smoke message into an audible alarm signal is performed by the IO control board, which has RS232 communication capabilities.

[0118] In another embodiment, the IO control board is also used to receive the push rod positioning signal, convert it into a trigger signal for CCD imaging, and simultaneously drive the light source to flash.

[0119] In another embodiment, the IO control board can also interconnect with the PLC (Programmable Logic Controller) of the packaging box device to obtain the working status of the packaging box device and control the error alarm behavior of the packaging box device.

[0120] In another embodiment, the visual smoke box defect re-inspection system also includes an industrial control computer.

[0121] Specifically, the industrial control computer, acting as terminal 102, integrates the human-machine interface and visual inspection program of the cigarette pack packaging equipment, running them on the machine. On one hand, it provides a user-friendly interface; on the other hand, based on user configuration, it performs image inspection on the acquired verification images and missing cigarette pack re-inspection images, determining which images are unqualified. Based on the judgment results, it instructs the IO control board to trigger alarms and shutdowns, notifying the PLC control system to reject the cigarette packs. The industrial control computer is equipped with a large-capacity hard drive, capable of storing one year's worth of cigarette pack packaging image information for easy historical retrieval by the user.

[0122] In another embodiment, the shape of the carton can also be inspected during the visual inspection of cigarette strips.

[0123] Specifically, when the carton is picked up from the carton tray and is formed, the terminal 102 receives the forming information from the RS232 serial port of the IO control board, extracts a frame from the continuous video stream of the rear CCD industrial camera as a visual inspection image, determines whether the formed carton blank is in good shape, and at the same time determines whether the carton on the carton tray is placed upside down.

[0124] Furthermore, the molding information transmitted from the RS232 serial port of the IO control board is notified to the IO control board by the PLC through signal lines.

[0125] In another embodiment, after the cigarette pack packaging box is sealed, the terminal 102 associates the cigarette pack packaging box with a barcode and uses a barcode reader to provide traceable historical information.
