Description
Technical Field
[0001] The present invention relates to the field of tobacco industry automation, and particularly to an on-line automatic cigarette recycling system and method for defective cartons of cigarettes. Background Art
[0002] In the field of recycling defective cartons of cigarettes in the traditional tobacco industry, there have long been technical bottlenecks and efficiency pain points. The current mainstream manual operation mode not only requires a large amount of labor input, but also has significant technical limitations. Specifically, it is manifested as follows: 1. Inefficiency and high loss of manual operation The traditional manual recycling process relies on manual disassembly of cigarettes one by one. The daily processing volume is only 2,000 - 3,000 cigarettes. Moreover, due to uneven manual operation force during the sorting process, the cigarette damage rate is as high as 15% - 20%. At the same time, the accuracy of manual sorting is subject to individual experience differences, and it is difficult to achieve precise classification of cigarette lengths and filter tip types. The sorting error rate generally exceeds 10%. This traditional mode not only causes waste of resources, but also makes the recycled tobacco shreds unable to meet the same-level blending standard due to severe damage and can only be used at a lower grade, resulting in direct economic losses. 2. Technical bottlenecks of automated equipment Although some automated disassembly equipment has partially replaced manual labor, its technical architecture has significant defects: Positioning deviation problem: For equipment using traditional vision positioning systems, due to insufficient sensor accuracy (such as resolution lower than 0.1 mm) and poor algorithm robustness, when the cigarette posture changes, a positioning error of 5 - 10 mm is likely to occur, resulting in the cutting device accidentally touching the cigarette body and causing mechanical damage. For example, the air-blowing equipment used by a certain cigarette factory has a tobacco shred recovery rate of only 70% due to positioning deviation, and the proportion of damaged cigarettes reaches 12%.
[0003] Lack of intelligent control: Most equipment lacks the ability to dynamically adjust the posture of the carton of cigarettes. When the cigarettes are tilted or flipped during the conveying process, they cannot be automatically corrected, resulting in the failure of subsequent sorting processes.
[0004] Single cutting path: Existing cutting schemes generally adopt fixed-path algorithms, such as straight cutting or fixed-curve cutting, and cannot adapt to the gap characteristics of different cigarette arrangements. For example, the conventional cigarette arrangement gap is 0.5 - 1 mm, while the gap of slim cigarettes can reach 1.5 - 2 mm. The single cutting path leads to a 30% - 40% reduction in disassembly efficiency.
[0005] 3. Industry technology upgrade requirements As the tobacco industry accelerates its intelligent transformation, the limitations of existing technologies are becoming increasingly prominent. For example, the popularity of new composite filter rod cigarettes (such as those containing explosive beads and activated carbon filter rods) has put forward higher requirements on the adaptability of recycling equipment. Traditional steam-bombing equipment can no longer meet the recycling needs of high-end cigarettes because it cannot avoid the contamination of tobacco by the crushing of explosive beads. In addition, the industry standard "Specifications for the Determination and Treatment of Defective Cigarettes" (2024) clearly requires that the tobacco recovery rate must reach more than 90%, and the damage rate must be controlled within 5%. Existing equipment generally finds it difficult to meet the standards. Therefore, developing a defective cigarette recycling system that combines high precision, high adaptability and economy has become a technical problem that the industry urgently needs to solve. Summary of the invention
[0006] In view of this, the present invention provides an online automatic cigarette recycling system and method for defective cigarette cartons. The present invention is expected to solve the following technical problems: 1. How to achieve fully automatic and accurate disassembly of the outer packaging of cigarette cartons to avoid cigarette damage; 2. How to ensure the consistency of the cutting posture of boxed cigarettes and avoid compaction of cigarettes; 3. How to efficiently sort cigarettes and adapt to the needs of different cigarette rolling and packaging machines.
[0007] The technical solution adopted by the present invention to solve the above technical problems is: Defective carton online automatic cigarette recovery system, including The cigarette carton disassembly system is used for positioning, clamping, ring cutting and stripping of cigarette carton; it comprises a first conveyor belt with a limiting guide groove, the first conveyor belt is provided with a longitudinal cutting station, the longitudinal cutting station is provided with a longitudinal cutting ring knife on the upper part, and a side clamp trigger assembly and a longitudinal cutting side clamping plate are provided on the side part; when the cigarette carton is clamped at the longitudinal cutting station, the speed of the first conveyor belt is set to zero, and a tiny protrusion is generated on the surface of the outer packaging of the cigarette carton due to the extrusion; a transfer platform is provided at the end of the first conveyor belt, the transfer platform comprises a transfer trigger assembly and a cigarette carton tearing device with a suction cup, the cigarette carton tearing device has a waiting station and a stripping station, and when located at the stripping station, the cigarette carton tearing device will turn upside down so that the longitudinal cutting opening of the cigarette carton is downward, and drive the suction cup to open to both sides to make the cigarette carton fall; The posture adjustment system is used for posture adjustment of cigarette packs and compaction of cigarettes; it includes a rotating pressing wheel and a first guide trough and a second guide trough. The first guide trough is used to change the random posture of cigarette packs into a longitudinal arrangement. A first visual detection mechanism and a first flipping mechanism are arranged behind the first guide trough to detect the posture of cigarette packs and adjust the front and rear directions of cigarette packs. A high-position drop track is arranged between the first guide trough and the second guide trough, which uses gravity and inertia to compact cigarettes so that cigarettes tend to one side of the cigarette pack to avoid the cutting end. The cigarette carton disassembling system is used for three-sided cutting of cigarette cartons and decomposition of cigarette carton packaging. It includes a transverse moving mechanism. Inside the operating area of the transverse moving mechanism, there are a transverse cutting station, a side cutting station, and a decomposition station. A disassembling suction cup and a second flipping mechanism are installed on it. When a cigarette carton is sucked by the disassembling suction cup and moves to the transverse cutting station, the front end face of the cigarette carton is cut by a transverse cutting circular knife. When the cigarette carton moves to the side cutting station, the side of the cigarette carton is cut by two symmetrically arranged side cutting circular knives by positioning the opposite spacing and the cigarette rod gap. When the cut cigarette carton moves to the decomposition station, the second flipping mechanism drives the lower surface of the cigarette carton to rotate downward, and the cigarette carton packaging is torn, causing the cigarette rods to fall due to gravity. The cigarette rod sorting system is used for visual sorting, rejection, and storage of cigarette rods. It includes a plate pushing stepped feeding device, which transports the messy cigarette rods to the fourth conveyor belt in the same direction or in a forward or reverse posture. Above the fourth conveyor belt, there is a second visual inspection mechanism for identifying defective cigarette rods and the information of the filter tip orientation. When it is a defective cigarette rod, it is rejected by a waste cigarette separation cylinder. When the orientation of the filter tip of the cigarette rod is reverse, it is pushed to the other side of the fourth conveyor belt by a cigarette rod forward and reverse separation cylinder. When the orientation of the filter tip of the cigarette rod is forward, it is not processed, so that the cigarette rods are transported and stored on both sides of the fourth conveyor belt according to the filter tip orientation.
[0008] Optionally, the longitudinal cutting side clamping plate is driven by a side clamping plate cylinder to apply a thrust of 0 - 10N to the strip of cigarettes to fix it.
[0009] Optionally, the longitudinal cutting circular knife cuts along the upper surface of the strip of cigarettes with a cutting depth of 1.2mm. When the cutting action is completed, the speed of the first conveyor belt resumes.
[0010] Optionally, the transfer table includes a transfer table base and a transfer table lifting arm rotatably installed thereon.
[0011] Optionally, the strip of cigarettes box tearing device is the actuating mechanism of the transfer table. When it is in a non-transfer state, it is located at the waiting station at the end of the first conveyor belt.
[0012] Optionally, when the strip of cigarettes box tearing device is at the peeling station, its suction cup opens to both sides under the drive of the suction cup base, causing the cigarette carton to fall into the cigarette carton bin. During the falling process of the cigarette carton, the transfer table drives the strip of cigarettes box tearing device to vibrate slightly.
[0013] Optionally, the strip of cigarettes box tearing device also has a waste material station. After the cigarette carton has fallen completely, the transfer table drives the outer packaging of the strip of cigarettes to the waste material station. The suction cup of the strip of cigarettes box tearing device stops sucking air, causing the outer packaging of the strip of cigarettes to fall into the strip of cigarettes packaging waste bin, and then the transfer table resets.
[0014] Optionally, the surface of the rotating pressing wheel is coated with silica gel and rotates at a speed of 10 r / min to prevent cigarette cartons from stacking or standing.
[0015] Optionally, a V-shaped material guiding groove is provided at the front ends of the first material guiding groove and the second material guiding groove.
[0016] Optionally, the first vision detection mechanism includes a first camera support and a first industrial camera mounted thereon, which is used to capture an image of the end face of the cigarette case for determining whether the cigarette case is upside down.
[0017] Optionally, the first flipping mechanism includes a first clamping cylinder.
[0018] Optionally, second conveyor belts and third conveyor belts are provided at both ends of the high-position falling track. The cigarette case slides from the second conveyor belt to the third conveyor belt through the high-position falling track with a vertical travel of 200 mm, so that the cigarette sticks are closely arranged on one side in the case and the distance from the front end face of the cigarette case is ≥5 mm to avoid damage during subsequent cutting.
[0019] Optionally, the width of the channel inlet of the second material guiding groove is 105 mm, and the width of the outlet is 58 mm to finely adjust the posture of the high-position falling cigarette case to a longitudinal arrangement.
[0020] Optionally, the transverse movement mechanism is arranged at the end of the third conveyor belt.
[0021] Optionally, the transverse movement mechanism includes a transverse movement mechanism main body. A disassembling suction cup cylinder, a disassembling suction cup base and a disassembling suction cup are installed at the front end of the transverse movement mechanism main body. A flipping base is installed at the rear end thereof through a flipping shaft. A second clamping cylinder body, a second clamping cylinder and a cigarette case clamping arm are installed at the front end of the flipping base.
[0022] After the cigarette case reaches below the disassembling suction cup, the disassembling suction cup cylinder moves downward, and the disassembling suction cup sucks air to suck the cigarette case. Then the disassembling suction cup cylinder moves upward to make the cigarette case leave the third conveyor belt, and the second clamping cylinder acts to make the cigarette case clamping arm clamp the lower end of the side of the cigarette case.
[0023] Optionally, the transverse movement mechanism main body is installed on a transverse movement screw and moves horizontally along it.
[0024] Optionally, the transverse cutting circular knife is installed on a transverse cutting screw through a transverse cutting circular knife base, and a transverse cutting guide rod is further provided on one side thereof.
[0025] Optionally, the side cutting circular knife includes a first side cutting circular knife and a second side cutting circular knife, and the distance therebetween is adjustable to adapt to different cigarette stick specifications. During cutting, the transverse movement mechanism drives the cigarette case to pass through the side cutting circular knife at a speed of 0.1 m / s, so that the tool cuts in along the gap between the cigarette sticks, and the cutting depth is 1.2 mm.
[0026] Optionally, at the end of the running area of the transverse movement mechanism, there are a cigarette placement area and a cigarette carton packaging placement area, and correspondingly, there are a cigarette bin and a waste bin for cigarette carton packaging below them respectively.
[0027] Optionally, when the transverse movement mechanism drives the cut cigarette cartons to move above the cigarette placement area, the disassembling suction cup maintains suction, and the turning shaft drives the second clamping cylinder to turn downward by 90°. At this time, the cigarette carton clamping arm and the disassembling suction cup move in opposite directions, tearing the cigarette carton packaging. At the same time, the transverse movement mechanism vibrates slightly back and forth to help the cigarettes fall quickly.
[0028] Optionally, after all the cigarettes have fallen, the second clamping cylinder stops operating. At this time, the cigarette carton packaging is completely sucked by the disassembling suction cup. When the transverse movement mechanism runs to the cigarette carton packaging placement area, the disassembling suction cup stops sucking, and the cigarette carton packaging falls into the waste bin for cigarette carton packaging.
[0029] Optionally, the plate pushing step feeding device includes a stepped conveyor belt and a pushing plate cooperating with it. The step height of the stepped conveyor belt is 5 mm, the spacing is 100 mm, and the reciprocating frequency of the pushing plate is 0.5 Hz.
[0030] Optionally, the second vision inspection mechanism includes a second industrial camera and a second camera support. By taking images of the cigarette surface, it identifies cigarette defects such as indentations and tears through a deep learning model. When it is a defective cigarette, the waste cigarette separation cylinder drives the push rod to remove the defective cigarette, which falls into the waste cigarette bin through the waste cigarette guide groove.
[0031] Optionally, at the end of the fourth conveyor belt, there is a first guide groove. When the cigarettes are conveyed to this position on both sides of the fourth conveyor belt according to the filter tip orientation, the forward cigarettes are located in the groove, and the reverse cigarettes are located outside the groove, and they respectively fall into the forward cigarette track and the reverse cigarette track, and are transported and automatically stored in the forward cigarette storage rack and the reverse cigarette storage rack.
[0032] Optionally, at the front end of the fourth conveyor belt, there is a second guide groove for making the feeding cigarettes located on one side of the fourth conveyor belt.
[0033] The present invention also adopts the following technical solutions to solve its technical problems: An online automatic cigarette recovery method for defective cartons of cigarettes, including S1.1 Cigarette Carton Positioning The cigarette cartons are sent into the longitudinal cutting station through the first conveyor belt with a limit guide groove. After being triggered, the longitudinal cutting side clamping plates are started, and the conveyor belt speed is set to zero; The cigarette cartons are fixed by the longitudinal cutting side clamping plates on both sides, and the positioning is completed, and a slight bulge is generated on the upper surface of the cigarette carton packaging, realizing the slight separation of the outer packaging of the cigarette carton and the cigarette carton; S1.2 Circumferential Cutting and Peeling The longitudinal cutting circular knife above the first conveyor belt cuts along the upper surface of the cigarette carton. After the cutting action is completed, the speed of the first conveyor belt resumes. The cigarette carton stripper waits at the end of the first conveyor belt in the non-transfer state. When the transfer action is triggered, the suction cups on the cigarette carton stripper start to act, fix the cigarette carton, and move to the peeling station through the transfer table. The cigarette carton stripper flips up and down so that the longitudinal cut of the cigarette carton faces downward, and drives the suction cups to open to both sides to make the boxed cigarettes fall. During the process of the boxed cigarettes falling, the transfer table drives the cigarette carton stripper to vibrate slightly to help the boxed cigarettes fall quickly. After the boxed cigarettes have fallen completely, the transfer table drives the outer packaging of the cigarette carton to the waste station. The suction of the suction cups on the cigarette carton stripper stops, and the outer packaging of the cigarette carton falls into the cigarette carton packaging waste bin. The transfer table resets. S2.1 Attitude guidance and detection The rotating pressure wheel rotates at a speed of 10 r / min to prevent the boxed cigarettes from stacking or standing. The first guide chute forces the boxed cigarettes to change from a random attitude to a longitudinal arrangement through a tapered structure. The first vision detection mechanism takes a picture of the end face of the boxed cigarettes to judge whether the boxed cigarettes are upside down. If an abnormality is detected, the first flipping mechanism is triggered to adjust the front and back orientation of the boxed cigarettes. S2.2 Cigarette rod compaction The boxed cigarettes slide from the second conveyor belt to the third conveyor belt through the high-position falling track. Using gravity and inertia, the cigarette rods are compacted so that the cigarette rods are arranged closely on one side of the cigarette box, with a distance of ≥5 mm from the front end face of the boxed cigarettes to avoid damage during subsequent cutting. The second guide chute fine-tunes the attitude of the high-position falling cigarette boxes to a longitudinal arrangement. S3.1 Boxed cigarette cutting The transverse movement mechanism waits at the end of the third conveyor belt. When the boxed cigarettes reach below the disassembly suction cup, the disassembly suction cup cylinder moves downward and the boxed cigarettes are sucked. The disassembly suction cup cylinder moves upward, making the boxed cigarettes leave the third conveyor belt. The second clamping cylinder acts, and the cigarette box clamping arm clamps the lower end of the side of the boxed cigarettes. When the boxed cigarettes run to the transverse cutting station, the transverse cutting circular knife cuts the front end face of the boxed cigarettes. When the boxed cigarettes run to the side cutting station, the side cutting circular knives symmetrically arranged on both sides cut the side of the boxed cigarettes by positioning the opposite spacing and the cigarette rod gap. S3.2 Packaging decomposition The transverse movement mechanism drives the cut boxed cigarettes to run above the decomposition station. The second clamping cylinder is driven to flip downward through the rotating shaft. The cigarette box clamping arm and the disassembly suction cup move in the opposite direction, and the cigarette box packaging is torn. At the same time, the transverse movement mechanism vibrates slightly back and forth to help the cigarette rods quickly fall into the cigarette rod placement area. After the cigarette sticks have all fallen, the second clamping cylinder stops operating. At this time, the cigarette carton packaging is completely held by the disassembly suction cup. The transverse movement mechanism moves to the cigarette carton packaging placement area, the disassembly suction cup stops sucking air, and the cigarette carton packaging falls into the cigarette carton packaging waste bin; S4.1 Board feeding Through the stepped conveyor belt and the push board, the messy cigarette sticks are uniformly transported to the fourth conveyor belt in the same or reverse orientation; S4.2 Visual sorting The surface image of the cigarette stick is captured by the second industrial camera. The cigarette stick defects such as indentations and tears are identified through a deep learning model, triggering the waste cigarette separation cylinder to drive the push rod to remove the defective cigarette sticks, which fall into the waste cigarette bin through the waste cigarette guide groove; The second industrial camera simultaneously outputs the orientation information of the cigarette stick filter tip. When the orientation of the cigarette stick filter tip is reverse, the cigarette stick positive and negative separation cylinder operates, driving the push rod to push the cigarette stick to one side of the fourth conveyor belt. If it is positive, it is not processed, so that the cigarette sticks are transported on both sides of the fourth conveyor belt according to the filter tip orientation; S4.3 Classified storage When the cigarette sticks pass through the first guide groove, the positive cigarette sticks are inside the groove, and the reverse cigarette sticks are outside the groove. Finally, they respectively fall into the positive cigarette stick track and the reverse cigarette stick track, and are transported and automatically stored in the positive cigarette stick storage rack and the reverse cigarette stick storage rack.
[0034] The beneficial effects brought by the present invention: I. Full-process automation Through modular design, the system realizes the full-process connection from strip cigarette disassembly, attitude adjustment, cigarette carton disassembly to cigarette stick sorting. Each system can be uniformly scheduled by the PLC controller, and precisely coordinated under the drive of multiple groups of cylinder and trigger sensor signals, with the beat error controlled within 0.2 seconds. The positioning and clamping, circumferential cutting and peeling in the strip cigarette disassembly link, the attitude correction of the V-shaped guide groove in the cigarette carton attitude adjustment, and the visual guidance and removal in the sorting link do not require manual intervention. Compared with traditional manual disassembly, the production efficiency is greatly improved. A single production line can replace 8-10 operators and support 24-hour continuous operation, which not only greatly reduces the labor cost, but also eliminates the random error of manual operation through the standardized process, and constructs a stable and efficient intelligent recycling system.
[0035] II. High-precision cutting System innovation adopts the high-precision cutting technology of "gap positioning - flexible cutting - dynamic peeling": During the disassembly of cartons of cigarettes, the longitudinal cutting circular knife precisely controls the cutting depth and accuracy to ensure that only the outer packaging is cut; during the disassembly of packets of cigarettes, by positioning the distance between packets of cigarettes and the gaps between cigarette sticks, the tool is guided to cut along the gaps between cigarette sticks to avoid contacting the main body of the cigarette sticks. Combined with the flexible adsorption of the disassembly suction cup and the shock-free falling design of the bottom edge flipping mechanism, the measured mechanical damage rate of cigarette sticks is reduced from 8.7% to 1.2%, and the breakage rate at the filter tip is reduced by 65%, maximizing the integrity of cigarette sticks, providing high-quality raw materials for subsequent sorting, and significantly enhancing the reuse value of recycled cigarette sticks.
[0036] III. Intelligent Sorting The vision sorting system integrates high-frame-rate industrial cameras and deep learning algorithms to achieve high-precision detection with an accuracy of over 99% for identifying defective cigarette sticks and filter tip orientations and a missed detection rate of defective cigarette sticks of <0.3%. The built-in product database of multiple models supports rapid self-calibration of parameters and can adapt to the cigarette stick specifications produced by different cigarette making and packing machines without stopping the machine. During sorting execution, the waste cigarette area cylinder can accurately remove defective cigarette sticks conveyed at high speed; with the help of the positive and negative discrimination cylinder and the first guide groove, the cigarette sticks are neatly stacked according to the filter tip orientation on different storage racks, and the automatic sorting efficiency is high. This technology breaks through the limitations of traditional contact detection and realizes the intelligent sorting of multiple models of cigarette sticks in a non-contact manner, significantly enhancing the flexible processing ability of the production line.
[0037] IV. Modular Design The system adopts a parametrically adjustable flexible architecture, and the control parameters can be quickly configured through the human-machine interface. The core system is an independent modular unit, and the equipment has strong scalability, perfectly adapting to the production needs of the cigarette industry with multiple varieties and small batches, and suitable for the disassembly requirements of different specifications of cigarette boxes.

Detailed implementation mode
[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0042] Moreover, the following description is for illustration rather than limitation. Specific details such as specific system structures and technologies are proposed to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.
[0043] Refer to Figure 1 , the first embodiment of the present invention relates to an on-line automatic cigarette recovery system for defective strip cigarettes, including a strip cigarette disassembly system 1, an attitude adjustment system 2, a box cigarette disassembly system 3, and a cigarette sorting system 4.
[0044] Refer to Figure 2, the strip cigarette disassembly system 1 is used for positioning, clamping, circumferential cutting, and peeling of strip cigarettes; it includes a first conveyor belt 102 with a limit guide groove 101. The first conveyor belt 102 is provided with a longitudinal cutting station. An annular longitudinal cutting knife 108 is installed above the longitudinal cutting station, and a side clamping touch photoelectric 115 and a longitudinal cutting side clamping plate 107 are installed on the side. When the strip cigarette 103 at the longitudinal cutting station is clamped, the speed of the first conveyor belt 102 is set to zero, and small protrusions are generated on the surface of the strip cigarette outer packaging due to extrusion. A transfer table is provided at the end of the first conveyor belt 102. The transfer table includes a transfer touch photoelectric 116 and a strip cigarette box tearing device 111 with a suction cup 1113. The strip cigarette box tearing device 111 has a waiting station and a peeling station. When located at the peeling station, the strip cigarette box tearing device 111 will turn over up and down so that the longitudinal cutting opening of the strip cigarette 103 faces downward, and drive the suction cup 1113 to open to both sides to make the box cigarettes fall.
[0045] Referring to FIG. 3, the cigarette carton tearing device 111 is an actuator of the transfer table, which realizes the disassembly and transfer of cigarette cartons 1111. When it is in the non-transfer state, it is located at the waiting station at the end of the first conveyor belt 102. The cigarette carton 1111 is sucked by the suction cup 1113 of the cigarette carton tearing device 111. The suction cup 1113 is installed on the suction cup base 1112, and the suction cup base 1112 is installed on the cigarette carton tearing device base 1114 through a rotating shaft 1115.
[0046] Optionally, when the cigarette carton tearing device 111 is located at the peeling station, its suction cup 1113 opens to both sides under the drive of the suction cup base 1112, causing the cigarette carton to fall into the cigarette carton bin 201. During the falling process of the cigarette carton, the transfer table drives the cigarette carton tearing device 111 to vibrate slightly.
[0047] Referring to FIG. 4, the attitude adjustment system 2 is used for adjusting the sorting attitude of cigarette cartons and compacting cigarette sticks; it includes a rotating pressure wheel 202, a first guide chute 203, and a second guide chute 210. The first guide chute 203 is used to change the random attitude of the cigarette carton into a longitudinal arrangement. A first vision detection mechanism and a first flipping mechanism 206 are arranged behind it, which are used to detect the position and attitude of the cigarette carton and adjust the front and back orientations of the cigarette carton. A high-drop track 209 is arranged between the first guide chute 203 and the second guide chute 210, which uses gravity and inertia to compact the cigarette sticks, making the cigarette sticks tend to one side of the cigarette box to avoid the cutting end.
[0048] Optionally, the first vision detection mechanism includes a first camera bracket 204 and a first industrial camera 205 installed thereon, which is used to capture the end face image of the cigarette carton and judge whether the cigarette carton is upside down based on a deep learning model.
[0049] Optionally, the first flipping mechanism 206 includes a first clamping cylinder 207.
[0050] Optionally, second conveyor belts 208 and third conveyor belts 211 are respectively arranged at both ends of the high-drop track 209. The cigarette carton slides from the second conveyor belt 208 through the high-drop track 209 with a vertical stroke of 200 mm to the third conveyor belt 211, so that the cigarette sticks are closely arranged on one side in the cigarette box and the distance from the front end face of the cigarette carton is ≥5 mm to avoid subsequent cutting damage.
[0051] Referring to FIG. 5, the cigarette box disassembling system 3 is used for three-sided cutting of the cigarette box and decomposition of the cigarette box packaging; it includes a transverse moving mechanism 306. Inside the operating area of the transverse moving mechanism 306, there are a transverse cutting station, a lateral cutting station, and a disassembling station. A disassembling suction cup 3068 and a second flipping mechanism are installed thereon. When the cigarette box is sucked by the disassembling suction cup 3068 and runs to the transverse cutting station, the front end face of the cigarette box with a larger gap is cut by the transverse cutting circular knife 305. When the cigarette box runs to the lateral cutting station, the side faces of the cigarette box are cut by the symmetrically arranged lateral cutting circular knives on both sides. When the cut cigarette box runs to the disassembling station, the second flipping mechanism drives the lower surface of the cigarette box to rotate downward, and the cigarette box packaging is torn, causing the cigarettes to fall due to gravity.
[0052] Referring to Figure 8 , optionally, the transverse cutting circular knife 305 is installed on the transverse cutting screw 302 through the transverse cutting circular knife base 304, and a transverse cutting guide rod 303 is also provided on one side thereof. During cutting, the transverse cutting circular knife base 304 moves horizontally on the transverse cutting screw 302 to drive the horizontal movement of the transverse cutting circular knife 305, ultimately achieving the cutting of the front end face of the cigarette box.
[0053] Referring to Figure 9 , optionally, the lateral cutting circular knives include a first lateral cutting circular knife 307 and a second lateral cutting circular knife 308. The opposing spacing between the first lateral cutting circular knife 307 and the second lateral cutting circular knife 308 is adjustable to adapt to the cutting requirements of different cigarette specifications, and the cutting surfaces of the first lateral cutting circular knife 307 and the second lateral cutting circular knife 308 coincide with the cutting surface of the transverse cutting circular knife 305. During cutting, the transverse moving mechanism 306 drives the cigarette box to pass through the lateral cutting circular knives at a speed of 0.1 m / s, thereby completing the cutting of the left and right end faces of the cigarette box, and thus completing the three-sided circumferential cutting of the cigarette box under the combined action of the transverse cutting circular knife 305, the first lateral cutting circular knife 307, and the second lateral cutting circular knife 308.
[0054] Optionally, the transverse moving mechanism 306 is arranged at the end of the third conveyor belt 211.
[0055] Referring to FIG. 6, the transverse moving mechanism 306 includes a transverse moving mechanism main body 3061. At the front end of the transverse moving mechanism main body 3061, a disassembling suction cup cylinder 3067, a disassembling suction cup base 3069, and a disassembling suction cup 3068 are installed. At the rear end, a flipping base 3065 is installed through a flipping shaft 3066. At the front end of the flipping base 3065, a second clamping cylinder body 3064, a second clamping cylinder 3063, and a cigarette box clamping arm 3062 are installed.
[0056] After the cigarette carton 3060 reaches below the disassembling suction cup 3068, the disassembling suction cup cylinder 3067 moves downward, and the disassembling suction cup 3068 sucks air to hold the cigarette carton 3060. Then the disassembling suction cup cylinder 3067 moves upward to make the cigarette carton 3060 leave the third conveyor belt 211. The second clamping cylinder 3063 acts to make the cigarette carton clamping arm 3062 clamp the lower end of the side of the cigarette carton 3060.
[0057] Optionally, the main body 3061 of the transverse movement mechanism is installed on the transverse movement screw 309 and moves horizontally along it.
[0058] Optionally, at the end of the operating area of the transverse movement mechanism 306, there are a cigarette rod placement area 311 and a cigarette carton packaging placement area 310, and below them there are respectively a cigarette rod bin 312 and a cigarette carton packaging waste bin 313.
[0059] Optionally, when the transverse movement mechanism 306 drives the cut cigarette carton 3060 to run above the cigarette rod placement area 311, the disassembling suction cup 3068 maintains suction, and the turning shaft 3066 drives the second clamping cylinder 3063 to turn downward by 90°. At this time, the cigarette carton clamping arm 3062 and the disassembling suction cup 3068 move in the opposite direction, causing the cigarette carton packaging to be torn. At the same time, the transverse movement mechanism 306 vibrates slightly back and forth to help the cigarette rods fall quickly. This process ensures that the poses of the cigarette rods in the cigarette carton remain consistent when the cigarette carton packaging is disassembled. Therefore, when the cigarette rods naturally fall into the cigarette rod bin 312, most of the cigarette rods have the same orientation, and a small number of cigarette rods change their orientation due to collisions, etc.
[0060] Optionally, after the cigarette rods have fallen completely, the second clamping cylinder 3063 stops acting. At this time, the cigarette carton packaging is completely held by the disassembling suction cup 3068. When the transverse movement mechanism 306 runs to the cigarette carton packaging placement area 310, the disassembling suction cup 3068 stops sucking air, and the cigarette carton packaging falls into the cigarette carton packaging waste bin 313.
[0061] Referring to FIG. 7, the cigarette rod sorting system 4 is used for visual sorting, rejection, and classified storage of cigarette rods; it includes a plate pushing stepped feeding device 414, referring to Figure 10, the plate pushing stepped feeding device 414 is used to lift the cigarettes falling into the cigarette bin 312 to the second guide groove 413 on the fourth conveyor belt 406. A second vision detection mechanism is arranged above the fourth conveyor belt 406 for identifying defective cigarettes and the filter tip orientation information. When it is a defective cigarette, it is removed by the waste cigarette separation cylinder 412. When the filter tip of the cigarette (defining that the orientation of the filter tip is opposite to the conveying direction of the fourth conveyor belt 406, that is, the orientation of the cigarette filter tip is reverse) is reverse, it is pushed to the other side of the fourth conveyor belt 406 by the cigarette positive and negative separation cylinder 411. When the filter tip of the cigarette (defining that the orientation of the filter tip is consistent with the conveying direction of the fourth conveyor belt 406, that is, the orientation of the cigarette filter tip is positive) is positive, it is not processed and this part of the cigarettes is the majority. The cigarettes are conveyed and stored on both sides of the fourth conveyor belt 406 according to the filter tip orientation.
[0062] Optionally, a first guide groove 405 is provided at the end of the fourth conveyor belt 406. When the cigarettes are conveyed to this position on both sides of the fourth conveyor belt 406 according to the filter tip orientation, the positive cigarettes are located in the groove and the reverse cigarettes are located outside the groove, and they respectively fall into the positive cigarette track 402 and the reverse cigarette track 403, and are transported and automatically stored in the positive cigarette storage rack 401 and the reverse cigarette storage rack 404.
[0063] Optionally, the longitudinal cutting side splint 107 is driven by the side splint cylinder 114 to apply a 5N thrust to the strip cigarette 103 to fix it, and the slight convex feature generated by the extrusion of the outer package of the strip cigarette is used to achieve the slight separation of the outer package of the strip cigarette and the boxed cigarette, and then the outer package of the strip cigarette is cut by the circumferential cutting tool.
[0064] Optionally, the longitudinal cutting circular knife 108 is installed on the longitudinal cutting station through the longitudinal cutting bracket 104, the longitudinal cutting guide rod 105 and the longitudinal cutting screw 106. The longitudinal cutting circular knife 108 cuts along the upper surface of the strip cigarette 103, and the cutting depth is 1.2mm. When the cutting action is completed, the speed of the first conveyor belt 102 resumes.
[0065] Optionally, the transfer table includes a transfer table base 112 and a transfer table lifting arm 113 rotatably installed thereon.
[0066] Optionally, the strip cigarette box tearing device 111 also has a waste material station. After the boxed cigarettes have fallen completely, the transfer table drives the outer package of the strip cigarette to the waste material station, and the suction cup 1113 of the strip cigarette box tearing device 111 stops sucking air, so that the outer package of the strip cigarette falls into the strip cigarette packaging waste bin 110, and then the transfer table resets.
[0067] Optionally, the surface of the rotating pressure wheel 202 is coated with silica gel and rotates at a speed of 10 r / min to prevent the boxed cigarettes from stacking or standing upright.
[0068] Optionally, a V-shaped material guiding groove is provided at the front ends of the first material guiding groove 203 and the second material guiding groove 210.
[0069] Optionally, the width of the channel inlet of the first material guiding groove 203 is 200 mm, and the width of the outlet is 58 mm.
[0070] Optionally, the width of the channel inlet of the second material guiding groove 210 is 105 mm, and the width of the outlet is 58 mm, so as to finely adjust the posture of the high-position falling cigarette boxes to be longitudinally arranged.
[0071] Optionally, the second vision detection mechanism includes a second industrial camera 410 and a second camera bracket 409. By taking images of the surface of the cigarette, it identifies cigarette defects such as indentations and tears through an existing deep learning model. When it is a defective cigarette, the waste cigarette separation cylinder 412 drives the push rod to remove the defective cigarette, which falls into the waste cigarette bin 407 through the waste cigarette guiding groove 408.
[0072] Optionally, a second guiding groove 413 is provided at the front end of the fourth conveyor belt 406 for positioning the feeding cigarettes on one side of the fourth conveyor belt 406.
[0073] The second embodiment of the present invention provides an online automatic cigarette recovery method for defective strip cigarettes, including S1.1 Strip cigarette positioning The strip cigarette 103 is sent into the longitudinal cutting station through the first conveyor belt 102 with a limiting guiding groove 101. The speed of the conveyor belt is as low as 0.2 m / s to avoid damage during side clamping; after triggering, the longitudinal cutting side clamping plate 107 is started, and the speed of the first conveyor belt 102 is set to zero; The strip cigarette 103 is fixed by the two longitudinal cutting side clamping plates 107 (the pressure adjustable range is 0-10 N), the positioning is completed, and a slight bulge is generated on the upper surface of the strip cigarette packaging, realizing the slight separation of the outer packaging of the strip cigarette and the boxed cigarette; S1.2 Circumferential cutting and peeling The longitudinal cutting circular knife 108 above the first conveyor belt 102 cuts along the upper surface of the strip cigarette 103, and the cutting depth is 1.2 mm (only penetrating the outer packaging without damaging the boxed cigarette). After the cutting action is completed, the speed of the first conveyor belt 102 is restored; The cigarette carton stripper 111 waits at the end of the first conveyor belt 102 in the non-transfer state. When there is a falling edge signal from the transfer trigger photoelectric sensor 116 at the front end, it indicates that the cigarette carton 103 has reached the position, triggering the transfer action. The suction cup 1113 on the cigarette carton stripper 111 starts to act, fixing the cigarette carton 103 and moving it to the stripping station through the transfer table; The cigarette carton stripper 111 flips up and down so that the longitudinal cut of the cigarette carton 103 faces downward, and drives the suction cup 1113 to open to both sides to make the cigarette cartons fall; During the process of the cigarette cartons falling, the transfer table drives the cigarette carton stripper 111 to vibrate slightly up and down and left and right to help the cigarette cartons fall quickly; After the cigarette cartons have fallen, the transfer table drives the outer packaging of the cigarette carton 103 to the waste station. The suction cup 1113 of the cigarette carton stripper 111 stops sucking air, and the outer packaging of the cigarette carton 103 falls into the cigarette carton packaging waste bin 110; Subsequently, the transfer table resets; S2.1 Attitude guidance and detection The rotary pressure wheel 202 rotates at a speed of 10 r / min to prevent the cigarette cartons from stacking or standing upright; The first guiding groove 203 forces the cigarette cartons to change from a random attitude to a longitudinal arrangement through a tapered structure; The first vision detection mechanism takes pictures of the end faces of the cigarette cartons to judge whether the cigarette cartons are upside down. If an abnormality is detected, the first flipping mechanism 206 is triggered to rotate 180° to adjust the front-back orientation of the cigarette cartons; S2.2 Cigarette rod compaction The cigarette cartons slide from the second conveyor belt 208 through the high-position falling track 209 (vertical travel 200 mm) to the third conveyor belt 211. The gravity and inertia are used to compact the cigarette rods so that the cigarette rods tend to be closely arranged on one side of the cigarette carton, with a distance of ≥5 mm from the front end face of the cigarette carton to avoid damage during subsequent cutting; The second guiding groove 210 finely adjusts the attitude of the high-position falling cigarette cartons to a longitudinal arrangement; S3.1 Cigarette carton cutting The transverse movement mechanism 306 waits at the end of the third conveyor belt 211. When the cigarette carton reaches below the disassembling suction cup 3068, the disassembling suction cup cylinder 3067 moves downward and the cigarette carton is sucked. The disassembling suction cup cylinder 3067 moves upward to make the cigarette carton leave the third conveyor belt 211. The second clamping cylinder 3063 acts, and the cigarette carton clamping arm 3062 clamps the lower end of the side of the cigarette carton; When the cigarette carton runs to the transverse cutting station, the transverse cutting circular knife 305 cuts the front end face of the cigarette carton; When the cigarette carton runs to the lateral cutting station, the lateral cutting annular knives symmetrically arranged on both sides position the opposite spacing and the cigarette gaps. The transverse movement mechanism 306 drives the cigarette carton to pass by the lateral cutting annular knives at a speed of 0.1 m / s. The cutting surfaces of the first lateral cutting annular knife 307 and the second lateral cutting annular knife 308 coincide with the cutting surface of the transverse cutting annular knife 305, so that the cutting tool cuts into the cigarette gaps, with a cutting depth of 1.2 mm, completing the cutting of the left and right end faces of the cigarette carton; S3.2 Packaging decomposition The transverse movement mechanism 306 drives the cut cigarette carton to run above the decomposition station. The second clamping cylinder 3063 is driven by the turning shaft 3066 to turn downward by 90°. The cigarette carton clamping arms 3062 and the disassembly suction cups 3068 move in the opposite direction, and the cigarette carton packaging is torn. At the same time, the transverse movement mechanism 306 vibrates slightly back and forth to help the cigarettes quickly fall into the cigarette placement area 311; After the cigarettes have fallen completely, the second clamping cylinder 3063 cancels its action. At this time, the cigarette carton packaging is completely sucked by the disassembly suction cups 3068. The transverse movement mechanism 306 moves to the cigarette carton packaging placement area 310, and the disassembly suction cups 3068 stop sucking air, and the cigarette carton packaging falls into the cigarette carton packaging waste bin 313; S4.1 Plate pushing and feeding Through the stepped conveyor belt cooperating with the push plate (reciprocating frequency 0.5 Hz), the messy cigarettes are uniformly transported to the fourth conveyor belt 406 in the same direction, either upright or upside down; S4.2 Visual sorting The second industrial camera 410 takes pictures of the surface of the cigarettes. Through the deep learning model, cigarette defects such as indentations and tears are identified, triggering the defective cigarette separation cylinder 412 to drive the push rod to remove the defective cigarettes, which fall into the defective cigarette bin 407 through the defective cigarette guide groove 408; The second industrial camera 410 simultaneously outputs the orientation information of the cigarette filter tips. When the orientation of the cigarette filter tips is reversed, the cigarette positive and negative separation cylinder 411 acts, driving the push rod to push the cigarettes to one side of the fourth conveyor belt 406. If it is upright, it is not processed, so that the cigarettes are transported on both sides of the fourth conveyor belt 406 according to the orientation of the filter tips; S4.3 Automatic storage When the cigarettes pass through the first guide groove 405, the upright cigarettes are inside the groove, and the reversed cigarettes are outside the groove. Finally, they respectively fall into the upright cigarette track 402 and the reversed cigarette track 403, and are transported and automatically stored in the upright cigarette storage rack 401 and the reversed cigarette storage rack 404.
