[0042] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0045] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0046] like Figures 1 to 9 As shown, an embodiment of the present invention provides a cigarette appearance defect detection system, comprising: a feeding device 1, a conveying device 2, a detection device 3 and a discharging device 4.

[0047] The conveying device 2 includes a first fixing component 21 and a conveying component 22. The first fixing component 21 includes a first fixing plate 211, two support plates 212 and a connecting plate 213. The support plates 212 are located on both sides of the first fixing plate 211, and grooves 214 are formed between the two support plates 212. The connecting plates 213 are respectively arranged on the top of the support plates 212; the conveying component 22 includes a conveyor belt 221, a first mounting plate 222 and two limit plates 223. The conveyor belt 221 is arranged in the groove 214, and the first mounting plate 222 is evenly spaced on the conveyor belt 221. The limit plates 223 are located at both ends of the first mounting plate 222. The cigarettes 5 are placed on the first mounting plate 222, and the two ends of the cigarettes 5 are abutted against the connecting plates 213.

[0048] Specifically, during use, the operator places the cigarette 5 on the limiting plate 223 and activates the drive assembly 23, causing the drive assembly 23 to rotate the conveyor belt 221. At this point, the limiting plate 223 supports and limits the cigarette 5, preventing it from slipping off the first mounting plate 222. Furthermore, because the cigarette 5 abuts the connecting plate 213, the friction between the cigarette 5 and the connecting plate 213 drives the cigarette 5 to rotate as it moves, enabling the inspection device 3 of the cigarette appearance inspection system to perform a comprehensive inspection of the cigarette 5.

[0049] The feeding device 1 is located at the head end of the conveyor belt 221 and is used to load cigarettes 5 into the conveyor belt 221 .

[0050] The detection device 3 includes a first detection component 31, a second detection component 32, a third detection component 33 and a fourth detection component 34 which are arranged in sequence from the head end of the conveyor belt 221 to the tail end of the conveyor belt 221. The first detection component 31 is used to detect the tobacco filler condition at the head end and the state of the tail end of the cigarette 5. The second detection component 32 is used to detect the state of the wrapping paper at the head and tail ends of the cigarette 5. The third detection component 33 is used to detect the state of the wrapping paper at the center position of the cigarette 5. The fourth detection component 34 is used to detect the tobacco filler condition at the center position of the cigarette 5.

[0051] The discharging device 4 is provided at the rear end of the conveyor belt 221 and is used for screening qualified cigarettes 5 from unqualified cigarettes 5 .

[0052] Specifically, when the cigarette 5 is transported to the first detection component 31 by the conveyor belt 221, the first detection component 31 detects the tobacco filler condition at the front end and the state of the tail end of the cigarette 5. If it meets the requirements, the cigarette 5 is marked as a qualified cigarette 5. If it fails to meet the requirements, the cigarette 5 is marked as an unqualified cigarette 5 in terms of the tobacco filler condition at the front end of the cigarette 5 and / or the state of the tail end.

[0053] Next, when the cigarette 5 is transported to the second detection component 32 by the conveyor belt 221, the second detection component 32 detects the status of the wrapping paper at the head and tail ends of the cigarette 5. If it meets the requirements, the cigarette 5 is marked as a qualified cigarette 5. If it fails to meet the requirements, the cigarette 5 is marked as an unqualified cigarette 5 in terms of the status of the wrapping paper at the head end and / or the tail end of the cigarette 5.

[0054] Next, when the cigarette 5 is transported to the third detection component 33 by the conveyor belt 221, the third detection component 33 detects the status of the wrapping paper at the center of the cigarette 5. If it meets the requirements, the cigarette 5 is marked as a qualified cigarette 5. If it fails to meet the requirements, the cigarette 5 is marked as a cigarette 5 with unqualified status of the wrapping paper at the center of the cigarette 5.

[0055] Next, when the cigarette 5 is transported to the fourth detection component 34 by the conveyor belt 221, the fourth detection component 34 detects the tobacco filler condition at the center position of the cigarette 5. If it meets the requirements, the cigarette 5 is marked as a qualified cigarette 5. If it fails to meet the requirements, the cigarette 5 is marked as a cigarette 5 with unqualified tobacco filler condition at the center position of the cigarette 5.

[0056] Moreover, since the cigarette 5 is in contact with the connecting plate 213, the cigarette 5 is in a rotating state. After each rotation of the cigarette 5 by 120°, the second detection component 32, the third detection component 33, and the fourth detection component 34 photograph the cigarette 5 three times in a row, thereby photographing the entire cigarette 5.

[0057] The present invention drives the conveyor belt 221 to rotate through the driving component 23. Since the cigarette 5 is in contact with the connecting plate 213, the friction between the cigarette 5 and the connecting plate 213 will drive the cigarette 5 to rotate while moving, so that the first detection component 31 detects the tobacco filler condition at the head end and the state of the tail end of the cigarette 5, the second detection component 32 detects the state of the wrapping paper at the head end and the tail end of the cigarette 5, the third detection component 33 detects the state of the wrapping paper at the center of the cigarette 5, and the fourth detection component 34 detects the tobacco filler condition at the center of the cigarette 5, and screens out qualified cigarettes 5 and unqualified cigarettes 5 through the detection results, thereby effectively preventing defective cigarettes 5 with defects in appearance from flowing into the next process and avoiding unqualified cigarettes 5 from entering the market, reducing the labor intensity of operators, and improving detection efficiency, effectively ensuring the quality and pass rate of cigarette 5 production, and improving the production efficiency of the enterprise.

[0058] In one embodiment of the cigarette appearance defect detection system of the present invention, Figure 1 and Figure 2 As shown, the first detection component 31 includes two first brackets 311, a first detection camera 312 and a first light source 313.

The first detection camera 312 and the cigarette 5 are in a horizontal state, and the first detection camera 312 and the first light source 313 are both arranged on the first bracket 311. The first detection camera 312 shoots the head end or tail end of the cigarette 5 through the first light source 313.

[0059] The present invention arranges two first brackets 311 on the support plates 212 on both sides of the conveyor belt 221, respectively, with the first detection camera 312 and the cigarette 5 in a horizontal state, and both the first detection camera 312 and the first light source 313 are arranged on the first bracket 311, so that the first detection camera 312 can photograph the front end or the rear end of the cigarette 5 through the first light source 313, thereby being able to detect the tobacco filler condition at the front end of the cigarette 5 and the condition of the rear end.

[0060] In one embodiment of the cigarette appearance defect detection system of the present invention, Figure 1 and Figure 2 As shown, the second detection component 32 includes two second brackets 321, a second detection camera 322, a first connecting frame 323 and a second light source 324. The two second brackets 321 are respectively arranged on the support plates 212 on both sides of the conveyor belt 221. There is an angle between the second brackets 321 and the conveyor belt 221. The second detection camera 322 is arranged on the second bracket 321. The first end of the first connecting frame 323 is connected to the second bracket 321. The second light source 324 is arranged at the second end of the first connecting frame 323. The second detection camera 322 shoots the cigarette paper at the head end or tail end of the cigarette 5 through the second light source 324.

[0061] The present invention arranges the second detection camera 322 on the second bracket 321, connects the first end of the first connecting frame 323 to the second bracket 321, and arranges the second light source 324 at the second end of the first connecting frame 323, and enables the second detection camera 322 to photograph the cigarette paper at the beginning or end of the cigarette 5 through the second light source 324, thereby being able to detect the status of the wrapping paper at the beginning and end of the cigarette 5.

[0062] In one embodiment of the cigarette appearance defect detection system of the present invention, Figure 1 and Figure 2As shown, the third detection component 33 includes a third bracket 331, a third detection camera 332, a second connecting frame 333 and a fixed block 334. The bottom of the fixed block 334 is connected to the connecting plate 213 and is located above the conveyor belt 221.

The infrared light source 343 emits infrared rays, so that the fourth detection camera 341 can detect the tobacco filling condition at the center position of the cigarette 5.

[0066] In one embodiment of the cigarette appearance defect detection system of the present invention, Figure 4 、 Figure 5 and Figure 6 As shown, the conveyor belt 221 is tilted, with the angle between the plane of the conveyor belt 221 and the horizontal plane being 5-20 degrees. Specifically, the angle between the plane of the conveyor belt 221 and the horizontal plane is degrees. This arrangement allows the cigarettes 5 to be affected by gravity during transportation and to adhere to the limiting plate 223, further preventing the cigarettes 5 from falling off the first mounting plate 222. Furthermore, it allows the cigarettes 5 to rotate stably.

[0067] Furthermore, the first fixing assembly 21 also includes a first support frame 215 and a second support frame 216. The first support frame 215 and the second support frame 216 are respectively located at the two ends of the first fixing plate 211. The length of the first support frame 215 is greater than the length of the second support frame 216. This arrangement enables the conveyor belt 221 to be set to an inclined state.

[0068] The first fixing assembly 21 further includes a flat plate 217, which is disposed above the connecting plate 213. The flat plate 217 is provided with two openings 218. The width of the openings 218 is greater than the width of the limiting plates 223. The limiting plates 223 extend through the openings 218 and are located above the flat plate 217. Specifically, the openings 218 extend along the length of the flat plate 217, and the length of the openings 218 is less than the length of the flat plate 217.

[0069] The present invention enables the limiting plate 223 to move within the opening 218 , thereby effectively ensuring stability during the process of conveying the cigarettes 5 .

[0070] Furthermore, the conveying component 22 also includes a limiting rod 224, and two mounting holes are provided on the limiting plate 223.
