Description

Technical Field

[0001] The invention relates to the technical field of mechanical automation, and in particular to an automatic sorting and rejecting device for finished defective cigarettes. Background Art

[0002] In cigarette production, the appearance quality of cigarettes is crucial to product quality. However, current national standards such as GB / T22838.12-2009 stipulate the measurement indicators of cigarette appearance, including B-type quality defects such as punctures, oil spots, and yellow spots on the surface of cigarettes. However, at present, the determination of cigarette appearance defects mainly relies on manual monitoring. The personal conditions of the monitoring personnel, such as fatigue level, vision differences, and different understandings of the standards, will lead to differences in the judgment of the monitoring results, which may cause some cigarettes with appearance defects to enter the market, affecting the company's reputation and consumer experience.

[0003] In the past, tobacco companies mainly relied on manual operations to monitor and sort the quality of finished cigarettes. Manual sorting has many disadvantages: manual sorting is slow and difficult to meet the needs of large-scale production. With the continuous increase in tobacco production, manual sorting requires a lot of time and manpower, resulting in low production efficiency and increased production costs for enterprises. Manual monitoring is easily affected by subjective factors, such as workers' fatigue and concentration, and is prone to misjudgment and missed judgments.

[0004] Moreover, some minor defects may be difficult to detect through manual monitoring, which may lead to defective cigarettes entering the market. Long-term manual sorting puts a heavy burden on workers' bodies and easily causes occupational diseases. It also affects workers' work enthusiasm and work quality. Labor costs continue to rise, making companies invest more and more in manual sorting. This patent is about realizing automatic monitoring of the appearance of cigarettes, improving monitoring efficiency and the accuracy of monitoring results. Summary of the invention

[0031] In one embodiment, for the shaking mechanism, the shaking mechanism includes a vertical block 5 arranged above the blowing plate 30, the side of the vertical block 5 is fixedly connected with a cross-connecting plate 9, the cross-connecting plate 9 is slidably connected with a sliding rod 7, a compression spring 8 is arranged above the sliding rod 7, one end of the compression spring 8 is fixed below the cross-connecting plate 9, a fixed block 4 is fixedly connected above the blowing plate 30, the fixed block 4 is rotatably connected to the cam 6, the sorting mechanism includes a control box 10 arranged on one side of the supporting base 1, a second telescopic rod 21 is arranged on one side of the control box 10, one end of the second telescopic rod 21 is fixedly connected to the second push plate 22, a second conveyor belt 25 is arranged below the second push plate 22, and the second conveyor belt 25 is transmission-connected to the third rotating column 23 and the fourth rotating column 24.

[0032] In this embodiment, a defective product drop collection box is provided for the sorting mechanism so that the defective product drops remaining on the surface of the first conveyor belt 14 can be collected. Then, during sorting, the defective cigarette pieces previously scanned back and forth by the scanning plate 16 can be accurately pushed into the defective cigarette piece sorting box 26 through the first telescopic rod 19 to facilitate centralized processing by the working personnel. When screening cigarettes, the defective cigarettes can be accurately monitored through the scanning plate 16 to determine which are defective cigarettes. Then, the monitor 2 on the side of the supporting base 1 can be used to observe and remove them when they reach the surface of the second conveyor belt 25, thereby saving the time of the staff in screening cigarettes.

[0033] In one embodiment, for the support base 1, a monitor 2 is fixedly connected to one side of the support base 1, and a sorting box 26 is provided at one end of the side of the support base 1 away from the monitor 2, and the sorting box 26 is used to collect defective cigarettes.

[0034] In one embodiment, the third rotating column 23 is rotationally connected to the support base 1 , and a fourth rotating column 24 is provided on a side of the support base 1 away from the third rotating column 23 , and the fourth rotating column 24 is transmission-connected to the support base 1 .

[0035] In this embodiment, the support base 1 and the rotating column are provided to ensure stability during cigarette sorting.

[0036] In one embodiment, for the air pump 17 , a pipeline for providing power to the first telescopic rod 19 and the second telescopic rod 21 is provided on the side of the air pump 17 , the motor 11 is transmission-connected to the transmission belt 12 , and the transmission belt 12 is transmission-connected to the first rotating column 13 .

[0037] In this embodiment, when using an air pump for cleaning, a certain amount of air flow can be controlled on its surface, and the defective products can be blown away before the cigarette pieces arrive and enter the tobacco sorting box 26, or blown to the surface of the second conveyor belt 25 and fall into the defective product sorting box 26 as it rotates.

[0038] In one embodiment, for the support base 1 , a collection box for collecting garbage produced after smoke shaking is provided below the support base 1 , the second rotating column 15 is rotatably connected to the support base 1 , and the first rotating column 13 is also rotatably connected to the support base 1 .

[0039] In this embodiment, by setting up a collection box under the support base 1, defective cigarettes can be well collected and monitored in a centralized manner, reducing the working time of the staff.

[0040] In one embodiment, for the fixed edge guard 18 , a first telescopic rod 19 is fixedly connected inside the fixed edge guard 18 .

[0041] In this embodiment, two sets of side guards are provided to effectively prevent cigarettes from falling to one side when they are moved. Such a setting can achieve the expected cigarette travel route.

[0042] The working principle of the automatic sorting and rejection device for finished defective cigarettes in the present invention is that first, the staff puts the cigarette box into the front conveyor belt of the sorting device for transmission, with the surface with the label facing upward, and then drops the cigarette box onto the shaking plate 3 as the conveyor belt rotates.

[0043] As the cigarette box falls, the cam 6 of the shaking mechanism starts to rotate frequently and then squeezes the sliding rod 7 to rise, further compressing the compression spring 8, causing the sliding rod 7 to hit the shaking plate 3 above, and then the shaking plate 3 shakes back and forth with the cam 6, and the defective cigarettes are directly sent to the top of the first conveyor belt 14 after shaking.

[0044] If there are defective products, such as loose tape or broken internal packaging, they will be detected by the monitor 2, and the model of the cigarette pieces will be recorded. Then, as the motor 11 rotates, the first rotating column 13 will be driven to rotate, and then the first conveyor belt 14 will rotate, and then the cigarette pieces will be conveyed. The cigarette pieces will slide in sequence and will be pushed to one side by the first push plate 20 on the side of the fixed edge guard 18 for arrangement.

[0045] Then, during the transmission process, the output gear 27 will rotate and then drive the sliding rack 29 to slide, so that the scanning plate 16 moves above the cigarette pieces. During the movement, the labels are scanned by the front scanning plate 16. Defective products will be recorded in order by the scanning plate 16, and those that are not recorded will be pushed away by the second telescopic rod 21 to the inside of the sorting box 26. The sorting box 26 is provided with a slope inside, and can be placed in the front shaking mechanism again after inspection and packaging. When conveying above the first conveyor belt 14, the air pump 17 will control the blowing plate 30 to blow out airflow, and regularly blow away the residues remaining on the surface of the first conveyor belt 14, that is, to prevent the appearance of a large number of defective packages during transportation from affecting the movement of the cigarette pieces.

[0046] Subsequently, after the transportation on the surface of the first conveyor belt 14 is completed, it will reach the surface of the second conveyor belt 25. During the rotation of the second conveyor belt 25, normal packaged cigarettes will directly enter the detection completion stage, and damaged ones will be pushed away by the second push plate 22. There is a gap between the second conveyor belt 25 and the first conveyor belt 14, so that the damaged packages can fall into the collection box under the support base 1.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
