Moreover, the first feature being "above", "over" and "on the top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.
[0040] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0041] As Figures 1 to 4 shown, the present utility model provides a detection device for packing cigarette cartons, which includes a workbench 10, a pushing assembly 20 and a monitoring assembly. The workbench 10 includes a loading position and an unloading position along the first direction X; the pushing assembly 20 includes a push plate 21, and the push plate 21 can move relative to the workbench 10 to push the cigarette cartons 100 from the loading position to the unloading position; the monitoring assembly includes an image acquirer 31, a Hall sensor 32 and a magnet 33. One of the Hall sensor 32 and the magnet 33 is fixed to the workbench 10 and located between the loading position and the unloading position, and the other is installed on the pushing assembly 20 and is relatively fixed to the push plate 21. The Hall sensor 32 is communicatively connected to the image acquirer 31, and the image acquirer 31 is fixed to the push plate 21 for acquiring an image of the side of the push plate 21 facing the cigarette cartons 100.
[0042] Generally, first, the cigarette cartons 100 are stacked at the loading position, the cartons 200 are placed at the unloading position, and the opening of the carton 200 faces the side of the cigarette cartons 100. The push plate 21 moves along the first direction X to push the cigarette cartons 100 into the carton 200. However, due to misplacement, omission and other reasons during the previous stacking of the cigarette cartons 100, there may be situations such as the shortage of the number of cigarette cartons 100 in the carton 200 or the wrong brand name.
[0043] To this end, the cigarette carton packing detection device in this application further includes a monitoring component. The image acquirer 31 of the monitoring component can acquire the image of the cigarette 100. In this embodiment, the magnet 33 is installed on the workbench 10 and is located between the loading position and the unloading position. The Hall sensor 32 moves along the first direction X with the push plate 21. When the push plate 21 pushes the cigarette 100 from the loading position into the carton 200 at the unloading position, the Hall sensor 32 passes by the magnet 33 and is initially triggered; when the push plate 21 resets, that is, when it moves from the loading position to the unloading position, the Hall sensor 32 is triggered by the magnet 33 again. This time, the Hall sensor 32 commands the image acquirer 31 to capture the cigarette 100 and acquire the image of the cigarette 100 in the carton 200. By acquiring the image, it is analyzed whether there are situations such as a shortage in the number of cigarettes 100 or a wrong brand name in the carton 200.
[0044] In this way, by adjusting the installation position of the magnet 33 on the workbench 10, specifically, the distance of the magnet 33 from the loading position in the first direction X, the opening timing of the capture by the image acquirer 31 is controlled, which can avoid being unable to capture the full view due to being too close to the carton 200 or the image being blurred due to being too far from the carton 200.
[0045] Specifically, the image acquirer 31 is used to collect the stack images of the cigarettes 100 corresponding to various types of standard cigarette products and the appearance images of the cigarette boxes, and the obtained image data is used to establish a standard reference image database to generate a standard image template for online detection and comparison.
[0046] The image similarity comparison algorithm is used for analysis. According to the differences in the appearance morphological characteristics of the packages of various types of cigarettes 100, the performance of image matching algorithms such as comparing the color grayscale histogram, Hash value comparison, and pyramid template matching is compared to determine whether there is a defect in the wrong brand name. By selecting an appropriate color channel and performing threshold segmentation and mathematical morphology operations on the obtained grayscale image to obtain a binary image, edge detection is performed on this basis and compared with the standard stack reference image of the cigarettes 100 to determine whether there is a defect in missing cigarettes;
[0047] The detection result obtained by the image acquirer 31 is sent to the data management system of the unit through the interface. When a defect in missing cigarettes or wrong brand name is detected, an appropriate control signal is sent to the rejection mechanism of the unit, and information such as the defect type and occurrence time is recorded.
[0048] Optionally, the workbench 10 includes a load-carrying tabletop 11 and baffles 12. The load-carrying tabletop 11 is used to place the cigarettes 100. There are two baffles 12, which are respectively fixed on both sides of the load-carrying tabletop 11 in the second direction Y; the first direction X is perpendicular to the second direction Y. By setting the baffles 12, the movement of the cigarettes 100 in the second direction Y is restricted, preventing them from falling off the load-carrying tabletop 11 during the process of being sent by the push plate 21.
[0049] Optionally, the pushing component 20 further includes a linear guide rail 22 and a slider 23. The linear guide rail 22 is fixed to the workbench 10. The linear guide rail 22 is provided with a chute along the first direction X. The slider 23 is fixedly connected to the push plate 21. The slider 23 is slidably disposed in the chute. In this way, by providing the linear guide rail 22, the slider 23 carries the push plate 21 to move in the chute, and the movement track of the push plate 21 along the first direction X can be standardized.
[0050] Specifically, in the chute, a lead screw extending along the first direction X is provided. The slider 23 is threadedly connected to the lead screw, and the slider 23 cannot rotate with the lead screw in the chute. In this way, when the lead screw rotates, the slider 23 moves along the axis of the lead screw, that is, the first direction X.
[0051] In addition, a cylinder, an electric push rod or other mechanisms capable of realizing linear movement can also be used.
[0052] Optionally, the pushing component 20 further includes a gantry 24. At least two linear guide rails 22 are arranged in parallel. They are respectively fixed to the workbench 10 in the second direction Y. The sliders 23 are arranged in one-to-one correspondence with the linear guide rails 22. The gantry 24 is connected to at least two linear guide rails 22 through the sliders 23. The push plate 21 is fixed to the gantry 24; the first direction X is perpendicular to the second direction Y. In this way, the push plate 21 is connected to at least two mutually parallel linear guide rails 22 through the gantry 24, which can prevent the push plate 21 from flipping and swinging when pushing the cigarette cartons 100.
[0053] Optionally, the pushing component 20 further includes a support plate 25. The support plate 25 is L-shaped. One end of the support plate 25 is fixed to the push plate 21, and the other end is fixed to the gantry 24.
[0054] Specifically, the gantry 24 includes a first support member, a second support member and a first mounting member. The first support member and the second support member are respectively connected to the slider 23. The first mounting member connects the first support member and the second support member. One end of the support plate 25 is fixed to the first mounting member, and the other end is fixed to the push plate 21.
[0055] Optionally, a reinforcing rib 26 is provided at the connection end of the support plate 25 and the push plate 21. In this way, the structural strength between the support plate 25 and the push plate 21 can be strengthened.
[0056] Optionally, a mounting hole 211 is provided in the middle of the push plate 21. Part of the image acquirer 31 is installed in the mounting hole 211. Specifically, the image acquirer 31 includes a main body and a camera. The main body is installed on the side of the push plate 21 facing away from the cigarette cartons 100. The camera is inserted into the mounting hole 211 from this side, and the camera does not protrude from the mounting hole 211 on the other side. To avoid the camera contacting the cigarette cartons 100 when the push plate 21 pushes the cigarette cartons 100, resulting in the camera being blurred or worn.
[0057] Optionally, a mounting base 27 is fixed to the push plate 21, and the image acquirer 31 is mounted on the mounting base 27. For the stability of the image acquirer 31, a mounting base 27 is fixed to the side of the push plate 21 facing away from the cigarette strip 100, and the main body of the image acquirer 31 is mounted on the mounting base 27.
[0058] Optionally, the monitoring component further includes a supplementary light 34. The supplementary light 34 is annular and sleeved on the outer peripheral side of the lens of the image acquirer 31.
[0059] In this way, the supplementary light 34 adopts a stroboscopic mode, so that the image acquirer 31 can obtain a high-definition detection image within a short exposure time, ensuring that the image acquirer 31 can accurately identify the type of the cigarette strip 100 and determine whether there is a problem of missing strips.
[0060] Optionally, the cigarette strip packing detection device further includes a cardboard box conveying rack 13. The cardboard box conveying rack 13 is connected to the discharging position of the workbench 10. A stop block is arranged at the discharging position. The stop block includes a first position and a second position relative to the workbench 10. When in the first position, the stop block is abutted against the cardboard box 200 on the side of the cardboard box 200 facing away from the push plate 21; when in the second position, the cardboard box 200 can enter the cardboard box conveying rack 13. Since when the push plate 21 pushes the cigarette strip 100 into the cardboard box 200, the cigarette strip 100 gives the cardboard box 200 a movement in the same direction away from the loading position. When the moving direction of the two exceeds the moving range of the push plate 21, there will be a situation where the cigarette strip 100 is not completely loaded into the cardboard box 200, which is not convenient for subsequent transportation and sealing. For this reason, a stop block is provided to limit the movement of the cardboard box 200 along the first direction X. When the cigarette strip 100 moves towards the cardboard box 200, the stop block is in the first position. After the cigarette strip 100 is completely loaded, the baffle 12 switches to the second position, so that the cardboard box 200 enters the cardboard box conveying rack 13 and enters the next processing flow.
[0061] Specifically, the baffle 12 can be arranged on the load-carrying table surface 11 by means of lifting or folding. This is the prior art and will not be elaborated here.
[0062] In addition, the above is only the preferred embodiment of the present invention and the applied technical principle. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
