Description

Technical Field

[0001] This utility model relates to a device for photographing the appearance of cigarette packs, belonging to the field of cigarette pack quality inspection technology. Background Technology

[0002] In cigarette production, cigarette cartons are typically placed on a conveyor belt to complete the cigarette packaging process. To improve the quality of cigarettes, it is necessary to inspect the cigarette cartons on the conveyor belt. Among these inspections, the detection of appearance defects is accomplished by taking pictures of each side of the cigarette cartons and performing image processing.

[0003] Because the bottom of the cigarette pack is located on the conveyor belt and blocked by it on the cigarette packaging production line, most existing cigarette packaging appearance inspection systems only detect defects on five surfaces of the cigarette packaging (including the front, back, left, right and top surfaces of the cigarette), resulting in the inability to remove unqualified products with defects on the bottom of the cigarette packaging.

[0004] According to the applicant, existing cigarette pack bottom-viewing devices typically require disconnecting the cigarette feed conveyor belt, dividing it into two sections, and then using a cigarette clamping conveyor mechanism to transfer the cigarette packs between the two sections. A camera is then positioned below the clamping conveyor mechanism to photograph the bottom of the packs. However, the complex production environment may prevent bottom-viewing of the cigarette packs by disconnecting the conveyor belt for various reasons. Furthermore, the cigarette clamping conveyor mechanism needs to be synchronized with the front and rear cigarette feed conveyors, increasing production costs. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a convenient device for photographing the bottom surface of cigarette packs that takes up little space.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a cigarette appearance shooting device, including a frame, and a first conveying mechanism and a second conveying mechanism disposed on the frame; the first conveying mechanism and the second conveying mechanism are arranged front and back along the cigarette conveying direction;

[0007] The first conveying mechanism includes a left first conveyor belt and a right first conveyor belt; the second conveying mechanism includes at least one second conveyor belt, which is disposed between the left first conveyor belt and the right first conveyor belt;

[0008] The frame is equipped with a first shooting component, a second shooting component, and a third shooting component; wherein, the first shooting component is used to shoot the bottom surface of the cigarette pack through the hollow area formed between the left first conveyor belt and the right first conveyor belt; the second shooting component is used to shoot the left end face of the cigarette pack and the bottom surface of the area between the second conveyor belt and the left end face of the cigarette pack; the third shooting component is used to shoot the right end face of the cigarette pack and the bottom surface of the area between the second conveyor belt and the right end face of the cigarette pack.

[0009] Existing cigarette pack appearance imaging devices use a large number of cameras, occupying a lot of space, resulting in slow subsequent algorithm processing speed and requiring improvement in detection efficiency. This invention uses three sets of imaging components to capture images of the small end faces on the left and right sides and the complete bottom surface of the cigarette pack, effectively reducing the number of imaging components and thus the number of cigarette pack images captured. This lowers production costs and improves detection efficiency. Attached Figure Description

[0015] This embodiment illustrates a device for photographing the appearance of cigarette packs, such as... Figures 1-3 As shown, the device includes a frame 1, and a first conveying mechanism and a second conveying mechanism disposed on the frame 1; the first conveying mechanism and the second conveying mechanism are arranged front to back along the cigarette conveying direction. Preferably, the first conveying mechanism and the second conveying mechanism are arranged adjacent to each other along the cigarette conveying direction, and they share a common drive roller at their adjacent connection point (i.e., Figure 1(See the first roller 11 shown). In this embodiment, by sharing a single drive roller, the first roller 11 and the second roller 12 drive the first conveying mechanism, and the first roller 11 and the third roller 13 drive the second conveying mechanism. Therefore, the first conveying mechanism and the second conveying mechanism can automatically synchronize, and the smoke-clamping conveying mechanism in the prior art (see the background art section) is eliminated. This also avoids the problem of increased production costs caused by the need for the smoke-clamping conveying mechanism to be synchronized with the front and rear smoke inlet conveyor belts.

[0016] like Figure 1 As shown, the first conveying mechanism includes a left first conveyor belt 21 and a right first conveyor belt 22; the second conveying mechanism includes at least one second conveyor belt 23, which is disposed between the left first conveyor belt 21 and the right first conveyor belt 22. Preferably, there are two second conveyor belts 23, both located between the left first conveyor belt 21 and the right first conveyor belt 22.

[0017] like Figure 2 and Figure 3 As shown, the frame 1 is equipped with a first shooting component 41, a second shooting component 42, and a third shooting component 43. The first shooting component 41 is used to photograph the bottom surface of the cigarette pack 2 through the hollow area formed between the left first conveyor belt 21 and the right first conveyor belt 22. The second shooting component 42 is used to photograph the left end face of the cigarette pack 2 and the bottom surface of the area between the second conveyor belt 23 and the left end face of the cigarette pack 2. The third shooting component 43 is used to photograph the right end face of the cigarette pack 2 and the bottom surface of the area between the second conveyor belt 23 and the right end face of the cigarette pack 2. Obviously, the width dimension of the second conveyor belt 23 is smaller than the length of the cigarette pack 2. When there are more than two second conveyor belts 23, the left side of the leftmost conveyor belt is called the left side of the second conveyor belt, and the right side of the rightmost conveyor belt is called the right side of the second conveyor belt. The width dimension of the second conveyor belt 23 is the distance between the left side and the right side of the second conveyor belt.

[0018] The first shooting component 41, the second shooting component 42, and the third shooting component 43 can all be conventional cameras or webcams. It should be noted that this embodiment only involves shooting the bottom surface and two small end faces of the cigarette pack. The other three sides of the cigarette pack are not obstructed by objects and can be shot using conventional methods, which will not be described in detail here.

[0019] This embodiment achieves the capture of the small end faces and complete bottom face of the left and right sides of the cigarette pack 2 without disconnecting the conveyor belt. It effectively integrates and reduces the number of capturing components, thereby reducing the number of images of the cigarette pack 2 captured, thus reducing production costs and improving detection efficiency.

[0020] Preferably, the distance between the left side of the left first conveyor belt 21 and the right side of the right first conveyor belt 22 is greater than or equal to the length of the cigarette pack 2; further, the right side of the left first conveyor belt 21 is adjacent to the left side of the second conveyor belt 23, and the left side of the right first conveyor belt 22 is adjacent to the right side of the second conveyor belt 23. In this way, the bottom surface of the cigarette pack 2 captured by the first shooting component 41 and the second shooting component 42 is approximately equal to the entire bottom surface of the cigarette pack 2.

[0021] Preferably, the first imaging component 41 images the bottom surface of the cigarette pack 2 through a first reflector, the second imaging component 42 images the left end face and bottom surface of the cigarette pack 2 through a second reflector, and the third imaging component 43 images the right end face and bottom surface of the cigarette pack 2 through a third reflector. Because the space in a cigarette packaging production line is relatively compact, the placement of the imaging components can be easily achieved through the arrangement of these reflectors. For example… Figure 3 As shown, when the first shooting component 41 shoots the bottom surface of the cigarette pack 2 through the first reflector, the first shooting component 41 can be set horizontally along the conveying direction of the first conveying mechanism, thereby reducing the installation height of the first shooting component 41; Furthermore, Figure 2 As shown, the second shooting component 42 and the third shooting component 43 are installed at a 25° angle to the horizontal plane, thereby positioning them above the first conveying mechanism. This improvement facilitates the installation and positioning of the first shooting component 41, the second shooting component 42, and the third shooting component 43, reducing space requirements.

[0022] Preferably, the first shooting component 41, the second shooting component 42 and the third shooting component 43 are respectively provided with a first supplementary light source 31, a second supplementary light source 32 and a third supplementary light source 33, collectively referred to as supplementary light sources, which provide supplementary light to the cigarette pack during shooting.
