Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette manufacturing, and particularly relates to a cigarette appearance detection device. Background Art

[0002] During each batch of cigarette production, a small trial run is required, followed by a comprehensive appearance inspection of the new cigarettes. This ensures that all functional components of the equipment are functioning properly and that parameter settings are correct. To avoid misjudgments, a small number of cigarettes are typically produced and individually inspected for appearance. Furthermore, during the actual production process, appearance spot checks are also conducted. A portion of cigarettes produced are randomly sampled from the production line and individually inspected to ensure the proper production process for the same batch. Current cigarette appearance inspection technology has completely replaced manual labor, significantly improving efficiency. The mainstream inspection technology uses CCD line or area array cameras to take high-speed photos of cigarettes, combined with image recognition technology, to fully detect appearance defects.

[0003] For example, the Chinese utility model patent (CN218650246U) discloses a cigarette appearance inspection device, which states: "The main body of the device is composed of a cigarette conveying drum, an inclined path, a pair of rollers, an inclined path and a camera, wherein the pair of rollers can rotate synchronously in the same direction, and an active member in the pair of rollers can open and close the gap channel between the pair of rollers to form a detection position by means of a transverse drive. When in use, the cigarette is fed to the detection position via the drum and the inclined path, and the pair of rollers drives the cigarette to rotate 360 ​​degrees, so that the camera above can obtain a complete unfolded image of the outer periphery of the cigarette. After the image is collected, the pair of rollers can be separated by a transverse drive, and the cigarette falls to the lower inclined path by its own weight and is sent to the subsequent process or equipment. The utility model can take a full circumferential picture of the cigarette to avoid blind spots, and take pictures of the cigarette. The process of detecting the appearance of cigarettes is more stable and reliable", and proposed: "For example, a method for detecting appearance defects based on the form of cigarette products, which obtains the appearance contour of the cigarette through an image acquisition device online and makes a judgment. However, this shooting method can only capture one-third or half of the circle of the cigarette, and when the cigarette is handed over on the cigarette wheel axle, there is also the problem of the cigarette itself rotating, resulting in the captured image being unable to determine whether it fully reflects the state of the cigarette. Another example is a solution for a device for detecting the appearance of cigarettes, which sets a shooting position for the cigarette, but the unfolding surface of the cigarette when it rotates is not at the same angle, which easily leads to the problem of focus change, especially when the rotation speed is too fast, there is a tendency for shooting blind spots, which increases the difficulty of image recognition". The technical deficiencies.

[0004] In summary, it can be seen that the following technical problems exist in the prior art: some existing cigarette appearance detection devices obtain the appearance outline of the cigarette through image acquisition and make a judgment, but this shooting method can only capture one-third or half of the cigarette circle, and when the cigarette is handed over on the cigarette wheel axle, there is also the problem of the cigarette itself rotating, resulting in the captured image being unable to determine whether it fully reflects the state of the cigarette. At the same time, the unfolding surface of the cigarette when it rotates is not at the same angle, which easily leads to the problem of focus change, especially when the rotation speed is too fast, there is a high probability of shooting blind spots, which makes image recognition more difficult. For this reason, the present application proposes a cigarette appearance detection device. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0024] As described in the background technology, some existing cigarette appearance detection devices obtain the appearance contour of the cigarette through image acquisition and make a judgment. However, this shooting method can only capture one-third or half of the cigarette's circle. When the cigarette is handed over on the cigarette wheel axle, there is also the problem of the cigarette's own rotation, resulting in the captured image being unable to determine whether it fully reflects the state of the cigarette. At the same time, the unfolding surface of the cigarette when it rotates is not at the same angle, which easily leads to the problem of focus change. Especially when the rotation speed is too fast, there is a high probability of shooting blind spots, which makes image recognition more difficult.

[0025] In order to solve this technical problem, the utility model provides a cigarette appearance detection device, which is applied to cigarette manufacturing;

[0026] It includes a stand 1, a first conveyor belt 2 is provided at the upper end of one end of the stand 1, a second conveyor belt 3 is provided at the lower end of the other end of the stand 1, a first motor 5 is also fixed inside the stand 1, a first gear disc 6 is fixed at the output end of the first motor 5, an intermittent conveying mechanism is provided on the outside of the stand 1 and between the first conveyor belt 2 and the first gear disc 6, a top frame 12 is fixed at the upper end of the stand 1 and at the upper end of the conveying mechanism, a first detection camera 13 is fixed at the bottom end of the top frame 12, and a full-scale shooting mechanism is also provided at one end of the stand 1 close to the second conveyor belt 3 and at the upper end of the second conveyor belt 3.

[0027] The cigarette appearance detection device provided by the present invention is designed with an overall structural coordination, so that the first motor 5 drives the first gear wheel 6 to rotate intermittently, so that after the cigarette falls into the intermittent conveying mechanism, it can briefly stay at the lower end of the first detection camera 13, and at the same time drive the cigarette to rotate, thereby facilitating the collection of a complete image of the outer periphery of the cigarette, and through the comprehensive shooting mechanism, conveniently collecting other appearance data such as the diameter of the cigarette to avoid blind spots.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] Example 1:

[0031] Please refer to Figure 1-4 A cigarette appearance inspection device includes a stand 1. To facilitate the transportation of cigarettes for inspection, a first conveyor belt 2 is provided at the upper end of one end of the stand 1. To transport inspected cigarettes to other processes or equipment, a second conveyor belt 3 is provided at the lower end of the other end of the stand 1. When cigarettes are transported by the first conveyor belt 2 or the second conveyor belt 3, multiple first partitions 4 are fixed to the outer sides of the first conveyor belt 2 and the second conveyor belt 3 to separate and transport the cigarettes in an orderly manner and avoid inspection confusion.

[0032] A first motor 5 is also fixed inside the stand 1, and a first gear disc 6 is fixed to the output end of the first motor 5. An intermittent conveying mechanism is provided on the outside of the stand 1 and between the first conveyor belt 2 and the first gear disc 6. The intermittent conveying mechanism facilitates intermittent conveying of cigarettes while driving the cigarettes to rotate to facilitate the capture of a complete image of the periphery and avoid blind spots. In order to facilitate image capture of the cigarettes in the intermittent conveying mechanism, a top frame 12 is fixed to the upper end of the stand 1 and located at the upper end of the conveying mechanism, and a first detection camera 13 is fixed to the bottom end of the top frame 12;

[0033] Specifically, the intermittent conveying mechanism includes a second toothed disc 7. The second toothed disc 7 is rotatably connected to the lower end of the outer side of the stand 1 and located between the first conveyor belt 2 and the first toothed disc 6. The second toothed disc 7 is meshed with the first toothed disc 6. A connecting seat 9 is provided on the side of the second toothed disc 7 away from the stand 1. A plurality of second partitions 8 are fixed between the second toothed disc 7 and the connecting seat 9. A second motor 10 is also fixed at the center of the interior of the second toothed disc 7. A supporting roller 11 is fixed to the output end of the second motor 10. The supporting roller 11 is located inside the plurality of second partitions 8. The cigarettes are supported by the supporting roller 11 and the cigarettes are separated by the plurality of second partitions 8.

[0034] The first gear wheel 6 is driven by the first motor 5 to rotate intermittently, and the meshing between the first gear wheel 6 and the second gear wheel 7 facilitates the intermittent rotation of the second gear wheel 7, thereby achieving the purpose of intermittent cigarette conveying, facilitating the cigarette to briefly stop at the lower end of the first detection camera 13, so that the first detection camera 13 can capture a complete image of the cigarette periphery;

[0035] After the cigarette periphery inspection is completed, a full-scale photographing mechanism is provided at one end of the stand 1 close to the second conveyor belt 3 and located above the second conveyor belt 3. This full-scale photographing mechanism facilitates comprehensive collection of cigarette diameter and other appearance data to avoid blind spots.

[0036] Specifically, the comprehensive photographing mechanism includes an arc frame 14. The arc frame 14 is fixed to one end of the stand 1 close to the second conveyor belt 3 and located at the upper end of the second conveyor belt 3. An annular rack 15 is fixed to the inner side of the arc frame 14. A slide 16 is also slidably connected to the outer side of the arc frame 14. A second detection camera 19 is fixed to the bottom end of the slide 16. In order to facilitate the movement of the slide 16 outside the arc frame 14, thereby driving the second detection camera 19 to move and facilitate comprehensive photographing of cigarettes, a third motor 17 is fixed to the inner side of the slide 16. A gear 18 is fixed to the output end of the third motor 17. The gear 18 is located inside the arc frame 14 and is meshed with the annular rack 15.

[0037] The first detection camera 13 and the second detection camera 19 are both CCD area array cameras or CCD line array cameras;

[0038] Example 2:

[0039] The intermittent conveying mechanism provided in Example 1 is further optimized, specifically, as Figure 3 As shown, when a cigarette falls to the outside of the supporting roller 11 and is separated by a plurality of second partitions 8, in order to facilitate the self-rotation of the cigarette when the supporting roller 11 rotates, an anti-slip layer is provided on the outside of the supporting roller 11. The anti-slip layer is made of rubber. The anti-slip layer effectively increases the friction between the supporting roller 11 and the cigarette, thereby facilitating the self-rotation of the cigarette.

[0040] The use process of the cigarette appearance inspection device provided by the present invention is as follows: after the cigarette is transported by the first conveyor belt 2 and falls to the outside of the support roller 11, the cigarettes are separated by multiple second partitions 8, and the first motor 5 is started to drive the first toothed disc 6 and the second toothed disc 7 to rotate intermittently, so that each cigarette briefly stays at the lower end of the first detection camera 13 for easy detection, and its short stay time and rotation angle are preset for easy control. During the short stay, the second motor 10 is started to drive the support roller 11 to rotate, thereby causing the cigarette to rotate on its own to facilitate the first detection camera 13 to capture a complete image of the cigarette periphery. After the capture is completed, the short stay ends, and the cigarette is conveniently transported to the outside of the second conveyor belt 3 by the rotation of the second toothed disc 7 and is separated and transported in an orderly manner through multiple first partitions 4;

[0041] Before being transported outward to other processes or equipment through the second conveyor belt 3, the third motor 17 is started to drive the gear 18 to rotate. The engagement of the gear 18 with the annular rack 15 facilitates the sliding seat 16 to slide on the outside of the arc frame 14, making it convenient for the second detection camera 19 to move flexibly, so that the diameter of the cigarette and other appearance data can be fully captured without blind spots.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
