[0027] refer to Figure 5In the existing packaging machine, the prints are placed on the auxiliary material tray in the form of a print stack B, each print stack B includes a plurality of stacked prints B and a wrapping paper wrapping the plurality of prints B. When the packaging machine is in production, the operator removes the wrapping paper from the print stack B on the auxiliary material tray and puts the plurality of prints B into the print conveying feed slot in the wrapping and packaging process of the packaging machine. The inventor of the present application has found that in the process of pasting the prints to the cigarette packs, the following problems are likely to occur: Figure 1 The cigarette pack shown has multiple prints pasted on it. This type of cigarette pack does not meet the process requirements after packaging. At the same time, such problems can easily cause blockages, resulting in reduced machine efficiency. It also does not meet the modern production requirements of cigarette factories, greatly affecting production quality and efficiency.

[0028] The embodiment of the present application provides a cigarette packaging machine, including a cigarette pack printing and pasting device and a packaging machine controller. The printing and pasting device is used to paste printing b on cigarette pack A and detect the pasting status, and send a signal to the packaging machine controller when the printing and pasting are unqualified, and the packaging machine controller is activated to remove the unqualified cigarette packs, thereby improving the production quality.

[0029] In some embodiments, the cigarette packaging machine further includes a rejection component. The rejection component is arranged at the exit of the cigarette packaging machine, and is connected to the packaging machine controller by signal. When unqualified printing and pasting are detected, the packaging machine controller controls the rejection component to operate, and rejects cigarette packs with unqualified printing and pasting, so that the cigarette pack production process is more automated, thereby improving production efficiency and production quality.

[0030] Specifically, the rejecting component can blow the cigarette packs with unqualified printing and pasting off from the outlet of the packaging machine by blowing air to achieve rejection.

[0031] refer to Figure 2 The printing pasting device comprises a pasting part 1, a feeding part 2 and a detection part 3. The pasting part 1 is used to paste the printing b on the cigarette pack A. The feeding part 2 is used to provide the printing stack B to the pasting part 1. The detection part 3 comprises a stand 31 and a camera device 32. The stand 31 is arranged beside the pasting part 1. The camera device 32 is arranged on the stand 31 and is used to take pictures during the pasting process of the cigarette pack A and the printing b.

[0032] By taking photos and detecting during the process of pasting the print b and the cigarette pack A, it is convenient to detect in time when the print b is not pasted properly, and accurately remove the cigarette packs with unqualified print pasting, thereby ensuring the yield rate of cigarette packs and improving production quality.

[0033] Specifically, the photos taken by the photographing device 32 can be combined with image processing technology to identify the pasting condition of the print b, determine whether the pasting result of the print b is qualified, and improve the accuracy of the determination result.

[0034] In some embodiments, the camera device 32 is used to take a photo to obtain the state of the print b pasted on the cigarette pack A. Specifically, the detection component 3 also includes a print detection controller, which is electrically connected to the packaging machine controller of the cigarette packaging machine. The camera device 32 is connected to the print detection controller by signal. The print detection controller obtains the photos taken by the camera device 32 and performs image processing on the photos, and compares and analyzes with the template correctly adhered to a single print to determine whether the pasting result of the print b is qualified. If the pasting result is unqualified, a signal is sent to the packaging machine controller to remove unqualified cigarette packs.

[0035] In some embodiments, the photographing device 32 is used to take photos to obtain the number of prints b pasted on the cigarette package A; and / or, the photographing device 32 is used to take photos to obtain the position of the prints b pasted on the cigarette package A.

[0036] Specifically, the print detection controller detects the number and position of the pasted prints based on the taken photos, ensuring that only a single print b is pasted on each cigarette package A and that the pasting position of the single print is accurate, thereby reducing the occurrence of multiple prints being pasted and crooked prints being pasted, further improving the yield rate of cigarette packages, ensuring production quality, and better meeting product quality requirements.

[0037] refer to Figure 2 and 3 In some embodiments, the stand 31 is constructed as a bent piece. That is, the stand 31 includes a first portion extending in the height direction Z and a second portion extending in the transverse direction X. The second portion is connected to a higher end of the first portion in the height direction. The camera device 32 is disposed on the second portion of the stand 31, thereby taking a photo of the pasting of the print from above.

[0038] In some embodiments, the photographing device 32 includes a camera. The camera is detachably mounted on the second portion of the stand 31, which facilitates disassembly and debugging of the camera and improves convenience.

[0039] refer to Figure 3 In some embodiments, the camera device 32 is located above the pasting component 1 in the height direction Z. This arrangement enables the camera device 32 to more clearly photograph the printing pasting situation, thereby improving the accuracy of judging cigarette packs with unqualified printing pasting.

[0040] In some embodiments, the detection component 3 further includes an illumination device (not shown in the figure). The illumination device is located above the pasting component 1 in the height direction Z, and is used to provide illumination when the photographing device 32 takes photos.

[0041] Specifically, the lighting device includes a lighting lamp, which is installed just above the pasting component 1 to illuminate the print, so that the camera device 32 can clearly and brightly capture the photo of the print b and the cigarette pack A being adhered to each other.

[0042] In some embodiments, the pasting component 1 includes a negative pressure adsorption member. The negative pressure adsorption member is used to generate negative pressure to adsorb the print b and paste the print b onto the cigarette pack A.

[0043] Specifically, the negative pressure adsorption component is connected to the negative pressure source, which provides negative pressure for the negative pressure adsorption component. The negative pressure adsorption component adsorbs the print b through negative pressure, so that the print can be kept on the negative pressure adsorption component more stably, reducing the risk of the print falling off and improving the stability of the print pasting process.

[0044] In some embodiments, reference Figure 4 The negative pressure adsorption member includes a main body 11 and two adsorption parts 12 arranged on the main body 11 at intervals. A negative pressure air suction port is provided on the adsorption part 12. The negative pressure air suction port is used to generate negative pressure so that the two end regions of the print b along the length direction are adsorbed by the negative pressure air suction port, and the print b spans the interval between the two adsorption parts.

[0045] Cigarette Pack A Edge Figure 4 The horizontal direction X indicated by the middle arrow moves toward the negative pressure adsorption member, and the side of the cigarette pack A facing the negative pressure adsorption member (called the front end face) contacts the adsorbed print b and completes the pasting. During the pasting process, the two ends of the print b are squeezed and bent by the cigarette pack A and attached to the two side surfaces adjacent to the front end face of the cigarette pack A. The interval between the two adsorption parts 12 is greater than the size of the cigarette pack A along the longitudinal direction Y, so that the cigarette pack A can pass through the interval between the two adsorption parts 12.

[0046] refer to Figure 3 In some embodiments, the print pasting device further comprises a driving device 4. The driving device 4 is used to move the cigarette pack A through the interval between the two adsorption parts 12, so as to contact and adhere to the print b adsorbed by the two adsorption parts 12 during the movement.

[0047] In some embodiments, the driving device 4 includes a cylinder, the output end of which acts on a side (rear end face) of the cigarette pack A parallel to the front end face, so as to push the cigarette pack A to move toward the negative pressure adsorption member and pass through the gap between the two adsorption parts 12 .

[0048] refer to Figure 2 In some embodiments, the feeding component 2 includes a feeding trough. The inlet of the feeding trough is used to put the print stack B. The outlet of the feeding trough faces the pasting component 1 to feed the print B to the pasting component 1. Specifically, the feeding trough extends in the height direction Z to form a trough body extending a certain length along the height direction Z, so that the print stack B is placed in the feeding trough.

[0049] In some embodiments, the print pasting device further includes a glue pasting component 5. The glue pasting component 5 is arranged between the outlet of the feed trough and the pasting component 1, and is used to receive the print stack B from the outlet of the feed trough, separate a single print b from it, and then glue the print b, and then send the glued print b to the pasting component 1.

[0050] refer to Figure 2 In some embodiments, the print pasting device further includes a conveying channel 6. After the cigarette pack A is pasted with the print b by the pasting component 1, it reaches the conveying channel 6. The conveying channel 6 conveys the cigarette pack A pasted with the print b to the next process along the longitudinal direction Y, thereby improving production efficiency.

[0051] In some embodiments, the print pasting device further comprises a glue cylinder 7. The glue cylinder 7 is used to store glue and supply glue to the glue pasting component 5, so as to ensure that the glue pasting component 5 can continuously paste glue on multiple prints b, thereby improving work efficiency.

[0052] In some embodiments, the packaging machine controller is configured to send out an alarm signal after receiving a signal from the print detection controller indicating that the print pasting is unqualified three times in a row, to alert the operator to conduct inspection and processing.

[0053] In some embodiments, the cigarette packaging machine further includes a display which is connected to the packaging machine controller signal, and is used to obtain and display the photos taken by the camera 32, and to display a warning interface after the packaging machine controller sends out an alarm signal, so as to further remind the operator to check and handle the situation.
