Description

Technical Field

[0001] The utility model relates to a cigarette box end face photographing device for bulk package detection, belonging to the technical field of transparent paper bulk package detection. Background Art

[0002] Wrapping cigarette boxes with transparent paper is a very important packaging process in cigarette box production. The loose packaging defects of transparent paper on cigarette boxes have always been a quality problem that has plagued cigarette manufacturers, greatly affecting the packaging qualification rate of cigarette boxes. In particular, the two smallest end surfaces of the cigarette box are the folding and hot-sealing areas of the transparent paper. The loose packaging defects of cigarette boxes are mainly concentrated on these two end surfaces.

[0003] How to detect the loose packing defects of the two small end faces of cigarette boxes mentioned above? In the existing technology, mechanical probe detection is mostly used to detect the end faces of cigarette boxes through physical contact of the control needle, but the probe is prone to mechanical fatigue, which affects the precision and accuracy of the detection, and the detection efficiency is also low. In addition, the probe detection cannot intuitively display the transparent paper packaging status of the cigarette box and the actual defects, which is not conducive to the operator's further understanding of the production quality situation on site.

[0004] The applicant searched and found that Chinese patent with publication number CN10432617A discloses a small-pack bulk visual inspection device, in which the cigarette box is located in a card slot, and the upper and lower surfaces of the cigarette box (not the small end surface) are scanned by upper and lower laser sources, and then the image is captured by a camera head to analyze the defects of the transparent paper. However, in this patent, the cigarette box is located in a specific card slot, and an additional process is required to make the cigarette box enter the card slot, and the card slot cannot hold multiple cigarette boxes at a time, which reduces the inspection efficiency; Chinese patent with publication number CN208488389U discloses a FOCKE350 bulk visual inspection device, which still accommodates the cigarette box through the card slot, and an additional process is required to make the cigarette box enter the card slot, so the inspection efficiency is still insufficient.

[0005] The applicant further searched and found that a Chinese patent with publication number CN214824684U discloses a device for detecting defects of loose transparent paper packs of small cigarette boxes, in which a cigarette box fixing device cooperates with a rotating hollow tube to drive the cigarette box to rotate, thereby cooperating with a scanning camera to perform scanning and detection. However, since the cigarette box is clamped and fixed by the fixing device and rotates with the hollow tube, part of the surface of the cigarette box is covered by the fixing device, resulting in an incomplete detection of the loose pack condition on the surface of the cigarette box.

[0006] It should be noted that, for the convenience of description, the present invention refers to the two surfaces with the smallest areas in the cigarette box as "small end surfaces", and as mentioned above, the loose packing defects of the cigarette box are also mainly concentrated on these two small end surfaces. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a cigarette box end surface photographing device which can improve the photographing quality and efficiency of the cigarette box surface, thereby improving the detection efficiency and accuracy of subsequent bulk package detection.

[0008] In order to solve the above technical problems, the utility model proposes a cigarette box end face shooting device for bulk package detection, comprising a frame, two transparent baffles and two groups of shooting components, wherein the transparent baffles and the shooting components are both arranged on the frame; the two transparent baffles are respectively located on both sides of the cigarette box conveying channel, the distance between the two transparent baffles is greater than the distance between the two small end faces of the cigarette box, and the two groups of shooting components are respectively used to shoot the two small end faces of the cigarette box through the transparent baffles.

[0009] The utility model arranges transparent baffles on both sides of a cigarette box conveying channel. When a cigarette box on the cigarette box conveying channel passes through the transparent baffles, two small end faces of the cigarette box are just facing the transparent baffles, so that the two small end faces of the cigarette box can be photographed through the transparent baffles by a photographing component. After the photographing is completed, the picture is transmitted to a background device for bulk package defect identification.

[0010] The beneficial effects brought by the utility model are as follows: the utility model has a simple structure, and the shooting work can be completed by only setting transparent baffles and shooting components on both sides of the cigarette box conveying channel, and no specific card slot is required, thereby improving the shooting efficiency, and the utility model does not require an additional fixing device to clamp the cigarette box during shooting, so there is no defect of blocking the small end face of the cigarette box when the fixing device is clamped during shooting, thereby improving the shooting quality. In addition, the utility model can shoot multiple cigarette boxes at one time as needed, and only needs to transfer the stacked cigarette boxes through the cigarette box conveying channel to between the two transparent baffles to complete the shooting work, thereby further improving the shooting efficiency, which is conducive to improving the detection efficiency and accuracy of subsequent loose package detection.

[0015] As described in the background art, a cigarette box has six surfaces, of which the two surfaces with the smallest areas are called "small end surfaces". This embodiment is used to photograph these two small end surfaces to facilitate subsequent detection of transparent paper loose package defects.

[0016] This embodiment relates to a cigarette box end face photographing device for bulk pack detection, such as Figure 1 As shown, it includes a frame 1, two transparent baffles 2 and two groups of shooting components, and the transparent baffles 2 and the shooting components are both arranged on the frame 1; the two transparent baffles 2 are respectively located on both sides of the cigarette box conveying channel 4, and the distance between the two transparent baffles 2 is greater than the distance between the two small end faces of the cigarette box 5. The two groups of shooting components are respectively used to shoot the two small end faces of the cigarette box 5 through the transparent baffles 2, and the transparent baffles can be directly installed on both sides of the cigarette box conveying channel.

[0017] When in use, the cigarette box conveying channel 4 conveys the cigarette box 5 to be photographed between the two transparent baffles. At this time, the two small end faces of the cigarette box 5 face different transparent baffles 2 respectively, and the two sets of shooting components respectively shoot different small end faces of the cigarette box. Obviously, this embodiment can shoot multiple cigarette boxes at the same time. At this time, the multiple cigarette boxes conveyed by the cigarette box conveying channel need to be stacked up and down ( Figure 1 In the figure, two cigarette boxes are stacked), thus, the two sets of photos taken by the two shooting components can identify the small end surface loose packages of multiple cigarette boxes, thereby improving the detection efficiency. In this embodiment, when shooting, it is not necessary to additionally fix the cigarette boxes, so whether the cigarette box conveying channel has a device for fixing and clamping the cigarette boxes does not affect the use of this embodiment.

[0018] Preferably, Figure 1 and Figure 2 As shown, the shooting component includes a shooting element 3 and a fill light source 6, the lens of the shooting element 3 faces the transparent baffle 2, and the fill light source 6 is used to fill light for the shooting element 3, wherein the shooting element 3 can be a commonly used camera or shooting head, etc.; in addition, in order to facilitate the setting of the position of the shooting element 3, preferably, the shooting element 3 shoots the two small end faces of the cigarette box 5 through the reflector 10. Through the above improvement, the shooting element 3 and the reflector 10 can be set in the closed box 7, so as to protect the shooting element and the reflector, and prevent dust from falling on the lens of the shooting element 3 or the mirror surface of the reflector 10, which affects the shooting effect.

[0019] Preferably, Figure 1 and Figure 2As shown, the outer periphery of the transparent baffle 2 is provided with a mounting frame 8. At this time, the transparent baffle 2 and the mounting frame 8 are both arranged on the closed box body 7. A support portion bent in a direction away from the cigarette box conveying channel is provided above the mounting frame 8, and the fill light source 6 is arranged at the support portion; further, the support portion is provided with a light-transmitting groove 9 corresponding to the position of the fill light source 6. In this way, the fill light source can be easily replaced.
