Description

Technical Field

[0001] The utility model relates to the field of tobacco equipment, in particular to a cigarette pack splitting and reselecting device. Background Art

[0002] During the inspection of finished boxed cigarettes before leaving the factory, it may be found that the plastic film of the finished boxed cigarettes is wrinkled, dirty, contains tobacco, has irregular edges, and other finished boxed cigarettes (abbreviated as cigarette packs) that do not meet the factory requirements. However, the cigarette packs contain cigarettes that have passed the previous process inspection. If the cigarette packs that are rejected simply because of poor outer packaging are discarded, the scrap rate will be high and a large amount of various cigarette raw and auxiliary materials will be wasted. Therefore, such cigarette packs need to be unpacked and the cigarettes with intact quality after unpacking need to be collected. Manual work alone cannot meet production needs. Utility Model Content

[0041] like Figures 1 to 11 As shown, a cigarette pack splitting and reselecting system of the present invention includes a frame 1, in which a main plate 11 is fixed. Above the main plate 11 is a cigarette pack conveying and splitting space, and below the main plate 11 is a cigarette reselecting space.

[0042] The cigarette pack conveying and splitting space is provided with a cigarette pack transfer mechanism, a cigarette pack splitting mechanism 4, and a cigarette dumping mechanism 5. The cigarette pack is split into half cigarette packs 16 after the cigarette pack transfer mechanism and the cigarette pack splitting mechanism 4 cooperate. The cigarette dumping mechanism 5 dumps the cigarettes in the half cigarette packs 16 so that the cigarettes can enter the cigarette selection space below for classification and screening.

[0043] A belt box 6 and a sorting and detecting mechanism 7 are provided in the cigarette reselection space. The cigarettes are accurately transported to the sorting and detecting mechanism 7 through the belt box 6. The sorting and detecting mechanism 7 distinguishes good cigarettes from bad cigarettes by inspecting their appearance.

[0044] As one of the embodiments of the present invention, a loading mechanism 17 is provided on one side of the frame 1. The conveyor belt of the loading mechanism 17 transports the cigarette packs to the cigarette pack transfer mechanism. The loading mechanism 17 has various structural forms and can directly use existing technology to automatically load the cigarette packs, further reducing labor.

[0045] As one embodiment of the present invention, the cigarette pack transfer mechanism includes a cigarette pack grabbing mechanism 2 and a cigarette pack pushing mechanism 3, such as Figure 3 As shown, the cigarette pack grabbing mechanism 2 includes a grabbing support frame 21 and a grabbing member 22 that can move in the X direction and the Z direction. Here, the X direction refers to the left and right horizontal direction, and the Z direction refers to the up and down direction. In this embodiment, the grabbing member 22 adopts a vacuum suction cup. In other embodiments, the grabbing member 22 can also adopt other components that can grab and place cigarette packs. The grabbing support frame 21 is fixed to the main table 11. The grabbing support frame 21 is equipped with an X-direction grabbing transmission mechanism and a Z-direction grabbing transmission mechanism. The grabbing member 22 moves up and down relative to the grabbing support frame 21 through the Z-direction transmission mechanism 23, and the Z-direction transmission mechanism 23 moves left and right relative to the grabbing support frame 21 through the X-direction transmission mechanism 24. The X-direction grabbing transmission mechanism and the Z-direction grabbing transmission mechanism can adopt transmission forms such as rodless cylinders, slide cylinders or screw transmission mechanisms.

[0046] Furthermore, a steering drive member 25 for driving the grabbing member 22 to rotate is also installed on the Z-direction transmission mechanism 23. The steering drive member 25 can be a motor. The steering drive member 25 can be coordinated with a camera for detecting the direction of the cigarette pack to adjust the cigarette pack into a uniform direction before splitting, so as to facilitate the unification of detection standards in the subsequent cigarette classification and screening process.

[0047] As one of the embodiments of the present invention, Figure 4 As shown, a cigarette pack pushing hole 12 is provided on the main plate 11, and a conveying support plate 15 is provided across the cigarette pack pushing hole 12. After the cigarette pack is placed on the conveying support plate 15 by the cigarette pack grabbing mechanism 2, it is pushed to the cigarette pack dividing mechanism 4 by the cigarette pack pushing mechanism 3, as shown in FIG. Figure 5As shown, the cigarette pack pushing mechanism 3 includes a Y-direction movable plate 31 that can move in the front-back horizontal direction. The Y-direction movable plate 31 is located below the main table 11. A Y-direction pushing transmission mechanism 34 is provided at the bottom of the Y-direction movable plate 31. The transmission form can be a rodless cylinder, a slide cylinder or a screw transmission mechanism. A group of symmetrically arranged cigarette pushing rods 33 that can move toward or away from each other are installed on the Y-direction movable plate 31. The cigarette pushing rods 33 extend in the front-back horizontal direction. A cigarette pushing bent plate 32 extending out of the cigarette pack pushing hole 12 is vertically fixed on the cigarette pushing rod 33. In a specific embodiment, a gasket 321 is provided on the part of the bent plate that contacts the cigarette pack. To reduce damage and wear, when the two cigarette pushing rods 33 approach each other, the distance between the two opposite cigarette pushing bent plates 32 is less than the width of the cigarette pack; when the two cigarette pushing rods 33 move away from each other, the distance between the two opposite cigarette pushing bent plates 32 is greater than the width of the cigarette pack; in this embodiment, a cigarette clamping micro-motion track 35 extending in the left and right horizontal directions is fixed on the Y-direction movable plate 31, and the cigarette pushing rod 33 is slidably connected to the cigarette clamping micro-motion track 35. Vertical plates are fixed on both sides of the Y-direction movable plate 31, and a cigarette clamping cylinder 36 is installed between the vertical plates and the cigarette pushing rod 33. The telescopic action of the cigarette clamping cylinder 36 can drive the two cigarette pushing rods 33 to approach or move away from each other.

[0048] Furthermore, if Figure 4 As shown, heating plates 37 for hot stamping are fixed on the upper and lower sides of the conveying support plate 15. The plastic film on the outside of the cigarette pack is first heated by the heating plates 37 to facilitate subsequent cutting and splitting.

[0049] Furthermore, the cigarette pushing curved plates 32 on the cigarette pushing rod 33 are provided with three groups, which can push three cigarette packs at the same time.

[0050] As one of the embodiments of the present invention, the cigarette pack segmentation mechanism 4 includes a segmentation support frame 41, a segmentation knife 42 and two groups of symmetrically arranged residual smoke adsorption components 43. The segmentation support frame 41 is fixed to the main table 11. In this embodiment, the segmentation support frame 41 is a gantry frame. The segmentation knife 42 is detachably fixed to the segmentation support frame 41 and can be adjusted to the left and right position or the up and down position on the segmentation support frame 41. The blade head of the segmentation knife 42 faces the conveying support plate 15. The residual smoke adsorption component 43 includes a negative pressure adsorption tube and a half-cigarette pack turning member 44. The negative pressure adsorption tube is supported on the segmentation support frame 41. Figure 6 and Figure 7As shown, the half-cigarette pack turning part 44 includes a residual smoke stripping and turning support 441 fixed to the main table 11 and a residual smoke stripping and turning platform 442 that can rotate around the residual smoke stripping and turning support 441. The residual smoke stripping and turning platform 442 receives the split half cigarette pack 16 and rotates 90° to make the split surface of the cigarette pack face upward, and the residual smoke damaged by the split is sucked away by the negative pressure adsorption tube; in this embodiment, the half-cigarette pack turning part 44 uses a swing cylinder to realize the turning action, and the residual smoke stripping and turning support 441 is the support of the swing cylinder, and the rotating rod of the residual smoke stripping and turning platform 442 is the swing rod of the swing cylinder.

[0051] Furthermore, if Figure 8 As shown, the splitting knife 42 includes a knife holder 421, a pneumatic knife head 422, and a cutter 423. The knife holder 421 is detachably fixed to the splitting support frame 41, the pneumatic knife head 422 is mounted in the knife holder 421, and the cutter 423 is mounted at the lower end of the pneumatic knife head 422. The splitting knife 42 can be a pneumatic vibration knife or an electric vibration knife, both of which are existing technologies. They use pneumatic or electric drive to vibrate the blade up and down at high frequency, which facilitates and quickly cuts the material.

[0052] Furthermore, if Figure 4 As shown, a pressure plate 45 is also provided below the cutting support frame 41. This plate is located between the conveying support plate 15 and the pneumatic cutter head 422. This plate prevents the cigarette pack from tilting during cutting, which would affect the cutting effect. A cutting slit is provided in the middle of the pressure plate 45 to facilitate the extension of the cutter 42 to cut the cigarette pack and also to position the pack during cutting. One end of the pressure plate 45 is an inclined plate to facilitate the entry of the cigarette pack beneath the pressure plate 45.

[0053] Furthermore, the residual smoke stripping and turning table 442 is an L-shaped structure, and a cigarette pack baffle 443 is adjustably fixed to the residual smoke stripping and turning table 442, which facilitates the adjustment of the clamping position according to different cigarette pack sizes and prevents the half-cigarette pack 16 from turning smoothly. The residual smoke stripping and turning table 442 can also absorb the half-cigarette pack 16 by negative pressure, by providing a negative pressure hole connected to an air source in the residual smoke stripping and turning table 442.

[0054] As one of the embodiments of the present invention, Figure 4 As shown, two cigarette dropping holes 13 are symmetrically provided on the main table 11, and a tobacco receiving pipe 14 is fixed below the cigarette dropping hole 13. The cigarette dumping mechanism 5 is provided with two and corresponds to two half cigarette packs 16 respectively. The cigarette dumping mechanism 5 includes a horizontal pusher 51, a transfer flipping member 52 and a cigarette dumping guide member 53. The horizontal pusher 51 is installed on the main table 11 and can drive the transfer flipping member 52 to move horizontally in the left and right directions as a whole. The horizontal pusher 51 can adopt a rodless cylinder, a slide cylinder or a screw drive mechanism and other transmission forms. The transfer flipping member 52 includes a dumping and flipping support 521 and a rotating arm 522 that can rotate around the dumping and flipping support 521. A dumping and flipping platform 523 is fixed to one end of the rotating arm 522; as shown Figure 6 As shown, when the cigarette pack split surface is facing upward, the tilting and turning platform 523 and the residual smoke stripping and turning platform 442 jointly support the half cigarette pack 16. After the residual smoke is sucked away by the negative pressure adsorption tube, the residual smoke stripping and turning platform 442 is reset, and the tilting and turning platform 523 is rotated 180 degrees so that the cigarette pack split surface faces downward (as shown in FIG. Figure 7 As shown), the cigarette automatically rolls into the pipe 14; Figure 2 As shown, the cigarette guide 53 is a vertical guide plate that can prevent cigarettes from falling off during the turning process of the tilting and turning platform 523. The cigarette guide 53 is also connected to a lifting mechanism 54. In this embodiment, the lifting mechanism 54 adopts a cylinder. When the cigarettes have finished rolling, the lifting mechanism 54 lifts the cigarette guide 53, and the horizontal push member 51 pushes the transfer turning member 52 to move horizontally and release the half-empty cigarette pack 16 carton;

[0055] Furthermore, the tipping and turning platform 523 is an L-shaped structure, and a negative pressure hole connected to an air source is provided in the tipping and turning platform 523. The tipping and turning platform 523 maintains a negative pressure adsorption state during the turning process. After the push member 51 pushes the transfer turning member 52 to move horizontally, the tipping and turning platform 523 releases the negative pressure adsorption state, and the emptied half-cigarette pack 16 paper box falls into the waste cigarette box collection area.

[0056] Furthermore, guide rods 55 are provided on both sides of the lifting mechanism 54 to guide the lifting process of the inverted cigarette guide 53.

[0057] In this embodiment, the transfer flipping member 52 uses a swing cylinder to realize the flipping action, the tilting and flipping support 521 is the support of the swing cylinder, and the rotating rod of the rotating arm 522 is the swing rod of the swing cylinder.

[0058] As one of the embodiments of the present invention, Figure 9 As shown, the belt box 6 is provided with two and respectively corresponds to two receiving pipes 14, the belt box 6 includes a pulley 61, a belt 62 and two symmetrical clamping plates 63, the pulley 61 is rotatably connected between the two clamping plates 63, the belt 62 is driven by the pulley 61, and the surface of the belt 62 is evenly spaced and fixed with partitions 621, the distance between adjacent partitions 621 and the outlet width of the receiving pipe 14 are slightly larger than the diameter of a single cigarette; the belt 62 is a synchronous belt, and the side thereof in contact with the pulley 61 is a toothed structure, which can make the transmission process more stable; a counting sensor 64 is installed at the outlet of the belt box 6, which can be used to count the number of cigarettes conveyed by the belt box 6; arranging strips 65 are provided on both sides of the belt 62 for preventing the cigarettes from being transported in a disorderly manner. When the cigarettes fall into the adjacent partitions 621, the arranging strips 65 can prevent the disordered arrangement caused by the escape of a single cigarette;

[0059] Furthermore, a window 66 is provided on the clamping plate 63, and a magnetic cover is provided at the window 66, which is convenient for removing and cleaning the debris inside the belt box 6. The magnetic cover is made of a transparent material, such as organic glass, which is convenient for maintenance.

[0060] Furthermore, an air hole is opened on one side of the clamping plate 63, and the air hole is connected to a blower through a pipeline. When cleaning the belt box 6, air can be blown into the belt box 6 through the blower.

[0061] Furthermore, the belt box 6 is a triangular structure, the short side of the triangular structure is located at the upper level, and a guide bucket 67 is fixed between the bottoms of the two belt boxes 6, as shown in FIG. Figure 10 As shown, the guide bucket 67 is larger at the top and smaller at the bottom, and the guide bucket 67 is supported below the lowest point of the belt 62.

[0062] As one of the embodiments of the present invention, Figure 10 As shown, the sorting and detecting mechanism 7 includes a sorting bracket 74, on which two vacuum synchronous wheels 71 are rotatably installed, one above and one below. The vacuum synchronous wheel 71 is driven by a reducer. Cigarette storage grooves 72 are evenly arranged circumferentially on the circumferential surface of the vacuum synchronous wheel 71. The size of the cigarette storage grooves 72 matches the size of a single cigarette. The extension direction of the cigarette storage grooves 72 is parallel to the radial direction of the vacuum synchronous wheel 71. An adsorption hole is provided at the bottom of each cigarette storage groove 72, which is connected to an air source. The air source can be an air pump, a vacuum pump, a gas pipeline in a factory, etc. The adsorption strength of the adsorption holes on the same vacuum synchronous wheel 71 is consistent, and the adsorption strength of the adsorption holes on the lower vacuum synchronous wheel 71 is slightly greater than that of the adsorption holes on the upper vacuum synchronous wheel 71. When the cigarette adsorbed on the upper vacuum synchronous wheel 71 rotates to the lower vacuum synchronous wheel When the cigarette is above the empty synchronous wheel 71, it is attracted by the lower vacuum synchronous wheel 71 with greater attraction force, and the cigarette is turned over. The upper and lower vacuum synchronous wheels 71 cooperate to make the circumference of the cigarette completely visible. The left and right sides of the vacuum synchronous wheel 71 are respectively provided with CCD cameras 73 for capturing the appearance of the cigarette. In this embodiment, the central axis of the CCD camera 73 is located on the horizontal symmetry plane of the vacuum synchronous wheel 71, and the lens of the CCD camera 73 faces the side of the vacuum synchronous wheel 71, which is conducive to capturing the appearance of the circumference of the cigarette. The appearance image of the cigarette captured by the CCD camera 73 is compared with the image of the qualified cigarette to distinguish between good and defective cigarettes. Defective cigarettes include those with damaged cigarette bodies, damaged cigarette holders, protruding tobacco, and incomplete tobacco. This comparison process is a conventional technique and will not be described in detail.

[0063] Furthermore, an end face detection camera is also provided on the front side of each vacuum synchronous wheel 71. Since the direction of the cigarette packs in the previous process is unified, the direction of the cigarette holders can be uniformly facing the front during the sorting and detection process. The end face detection camera can capture the end face of the cigarette holder, further improving the good product detection standard and detection accuracy.

[0064] Furthermore, the upper vacuum synchronous wheel 71 rotates counterclockwise, conveying the cigarettes to the left side of the upper vacuum synchronous wheel 71, where the CCD camera 73 on the left side captures images of the cigarettes' appearance. The lower vacuum synchronous wheel 71 rotates clockwise, conveying the cigarettes to the right side of the lower vacuum synchronous wheel 71, where the CCD camera 73 on the right side captures images of the cigarettes' appearance. In this embodiment, after the cigarettes on the lower vacuum synchronous wheel 71 are inspected, their entire circumference is captured, and after separation of defective and good cigarettes, the defective and good cigarettes fall from the lower vacuum synchronous wheel 71 into corresponding collection boxes.

[0065] Furthermore, the adsorption state of the adsorption holes of each cigarette storage slot 72 on the lower vacuum synchronous wheel 71 is independently controlled. After the lower vacuum synchronous wheel 71 detects defective cigarettes by comparison, the negative pressure at the defective cigarettes disappears and the cigarettes fall into the defective product collection box 81 below. The good cigarettes fall into the good product collection box 82 when the lower vacuum synchronous wheel 71 continues to rotate clockwise to the top of the good product collection box 82.

[0066] In other embodiments, the way in which cigarettes fall off the vacuum synchronization wheel 71 is not limited to this. An air path may be provided at an external fixed position to blow good or bad cigarettes into the corresponding collection box.

[0067] Furthermore, the cross-sectional curvature of the cigarette storage slot 72 is a minor arc (an arc smaller than a semicircle) so as to present the appearance of the cigarette as much as possible, facilitating detection and comparison after being photographed by the CCD camera 73 .

[0068] Furthermore, light sources 75 are provided on the left and right sides of the vacuum synchronization wheel 71 , so that the appearance of the cigarette can be clearly presented in the image captured by the CCD camera 73 .

[0069] Furthermore, the CCD camera 73 is supported on a CCD camera mounting bracket 76 , and the light source bracket 77 is adjustably fixed on the CCD camera mounting bracket 76 .

[0070] As one embodiment of the present invention, a defective product collection box 81 and a good product collection box 82 are respectively provided on both sides of the lower vacuum synchronous wheel 71. A first guide groove 83 is also obliquely provided between the defective product collection box 81 and the lower vacuum synchronous wheel 71. The higher end of the first guide groove 83 is located at the lower middle part of the right side of the lower vacuum synchronous wheel 71, and is used to receive defective cigarettes that have escaped from the right side of the lower vacuum synchronous wheel 71. The lower end of the first guide groove 83 is located above the defective product collection box 81, and the top of the defective product collection box 81 is open.

[0071] like Figure 11As shown, a second guide groove 84 is obliquely arranged between the good product collection box 82 and the lower vacuum synchronization wheel 71. The higher end of the second guide groove 84 is located directly below the lower vacuum synchronization wheel 71, and is used to receive the good cigarettes detached from the lower part of the lower vacuum synchronization wheel 71. The lower end of the second guide groove 84 is located above the good product collection box 82. The top of the good product collection box 82 is open, and the bottom of the good product collection box 82 includes an inclined surface 821 and a horizontal surface 822. The inclined surface 821 can make the good cigarettes slowly slide into the bottom of the good product collection box 82 to avoid further damage to the good cigarettes. At the same time, it can make the good cigarettes that fell in the early stage be preferentially stacked on the left side of the good product collection box 82.

[0072] The first guide groove 83 and the second guide groove 84 are smoothly connected to the corresponding collection box to ensure that the cigarettes fall smoothly into the collection box. The first guide groove 83 and the second guide groove 84 are staggered, which is conducive to the diversion of defective cigarettes and good cigarettes.

[0073] Furthermore, the good product collection box 82 is arranged on the left and right, and the lower end of the second guide groove 84 is located on the right side of the lower vacuum synchronization wheel 71, so that the opening of the good product collection box 82 can be extended to the right side of the lower vacuum synchronization wheel 71, which is conducive to expanding the storage volume of the good product collection box 82.

[0074] Furthermore, the bottom of the defective product collection box 81 and the side of the good product collection box 82 are respectively slidably connected to the rack 1 through the slide rails 85, so as to facilitate the removal and replacement of the collection box.

[0075] Furthermore, a handle 86 is provided at one end of the defective product collection box 81 and the good product collection box 82 for easy pulling.

[0076] Furthermore, an empty cigarette box recovery box 87 is provided under the main table 11 for recovering emptied half-cigarette packs 16 paper boxes. A guide tube 871 is fixed under the main table 11. The empty cigarette box recovery box 87 is located under the guide tube 871. The empty cigarette box recovery box 87 is slidably connected to the frame 1 through a slide rail 85.

[0077] Furthermore, a receiving pipe 14 for guiding the dumped cigarettes to the belt box 6 is fixed below the main table 11. A vibration bucket assembly is provided below the receiving pipe 14. The vibration bucket assembly includes a vibration support frame 881, a vibration connecting plate 882, a vibration rod 883, and a vibration cylinder 884. The vibration support frame 881 is fixed to the main table 11. The two ends of the vibration cylinder 884 are respectively connected to the vibration support frame 881 and the vibration connecting plate 882. The vibration rod 883 is fixedly connected to the vibration connecting plate 882 and is located below the receiving pipe 14. Every time a cigarette is dumped, the vibration cylinder 884 is activated, driving the vibration rod 883 to strike the receiving pipe 14 at least once, which can prevent cigarettes from remaining in the receiving pipe 14.

[0078] When the cigarette pack splitting and reselecting device is in use, it works according to the following steps:

[0079] Step S1, cigarette pack transfer: the cigarette pack to be split and selected is loaded onto the grabbing track of the cigarette pack grabbing mechanism 2. The grabbing member 22 of the cigarette pack grabbing mechanism 2 moves in the X and Z directions. After grabbing the cigarette pack, the cigarette pack is placed on the conveying support plate 15, and then the cigarette pack is pushed forward by the cigarette pack pushing mechanism 3.

[0080] During the forward movement of the cigarette pack, the cigarette pack can pass through the heating plate 37 via the cigarette pack pushing mechanism 3 , and the plastic film on the outside of the cigarette pack becomes brittle due to the heat, making it easy to cut.

[0081] During the forward movement of the cigarette pack, the initial position of the cigarette pushing bent plate 32 is that the Y-axis movable plate 31 is located at the rear side and the two opposite cigarette pushing bent plates 32 are open. After the grabbing member 22 of the cigarette pack grabbing mechanism 2 places the cigarette pack on the conveying support plate 15, the two opposite cigarette pushing bent plates 32 approach each other, and then the Y-axis movable plate 31 drives the cigarette pushing bent plates 32 to push the cigarette pack forward a certain distance (when three groups of cigarette pushing bent plates 32 are provided, the distance is the distance between two adjacent groups of cigarette pushing bent plates 32). At this time, the two opposite cigarette pushing bent plates 32 open and retreat to the initial position of the cigarette pushing bent plates 32, waiting to push the next cigarette pack.

[0082] Step S2 , cigarette pack splitting: the cigarette pack is pushed by the cigarette pack pushing mechanism 3 to the cigarette pack splitting mechanism 4 , and is cut by the splitting knife 42 into two split cigarette pack halves 16 .

[0083] After the cigarette pack is split, the half cigarette pack 16 is turned over by the half cigarette pack flipping member 44 so that the split surface of the cigarette pack faces upward. At this time, the negative pressure adsorption tube is used to absorb the remaining cigarettes damaged by the split (according to the arrangement of cigarettes, when the cigarette pack is arranged in a 776 arrangement, three cigarettes at the split surface of the cigarette pack are significantly damaged).

[0084] Step S3, dumping of cigarettes: After the damaged cigarette residues are peeled off, the half cigarette pack 16 is flipped over by the dumping and turning platform 523 so that the split surface of the cigarette pack faces downward, and the cigarettes automatically roll down under the action of their own weight.

[0085] The cigarette tipping guide 53 can be used to help the cigarette tipping, so as to prevent the cigarettes from falling off during the tipping and turning process of the tipping and turning platform 523.

[0086] After the cigarette rolls down, if a cigarette guide 53 is provided, the cigarette guide 53 is first lifted up by the lifting mechanism 54 to free up translation space for the transfer flipping member 52. If no cigarette guide 53 is provided, the transfer flipping member 52 is directly pushed to translate by the push member 51 and then the half-empty cigarette pack 16 paper box is released.

[0087] Step S4, cigarette reselection: the cigarettes enter the belt box 6 through the receiving pipe 14, and the belt box 6 separates adjacent single cigarettes and transmits them to the sorting and detection mechanism 7. The cigarettes are transferred from the upper vacuum synchronous wheel 71 to the lower vacuum synchronous wheel 71 in the sorting and detection mechanism 7 and then turned over. The CCD cameras 73 set on both sides jointly detect the circumferential appearance of the single cigarettes. The appearance image of the cigarette taken by the CCD camera 73 is compared with the image of qualified cigarettes to distinguish between good and defective cigarettes.

[0088] Step S5, cigarette collection: After the cigarettes on the lower vacuum synchronous wheel 71 are inspected, the entire circumference of the cigarettes is photographed, and after the defective cigarettes and the good cigarettes are distinguished, the defective cigarettes and the good cigarettes fall from the lower vacuum synchronous wheel 71 into the corresponding collection box respectively.
