Description

Technical Field

[0001] The present invention belongs to the technical field of detection, and specifically relates to a detection device for cigarette label printed matter. Background Art

[0002] During the production process of cigarette cases, the prepared hard paper is printed with corresponding patterns by a printing press. Subsequently, the printed paper is cut to form the basic shape of the cigarette case. Then, an inspection machine is used to detect whether there are unqualified products in the patterns printed on the paper;

[0003] An inspection machine is a machine for automatically detecting the printing quality of cardboard. It uses a camera, an auxiliary light source, and a set of computer graphic recognition software systems to scan the printed image. Qualified cardboard is conveyed out from the paper receiving part, and unqualified ones are automatically conveyed backward from the middle lower part of the machine; this enables the printing factory to completely get rid of the previous situation of relying on manual inspection, greatly improving labor productivity and the reliability of product quality. At the same time, it can also greatly shorten the printing delivery cycle and reduce the labor cost of the printing factory;

[0004] The inspection machine can effectively detect printing defects on various color images, such as stains, flying ink, missing printing, color difference, misregistration, knife wire, wrinkles, etc. The design of this machine pays attention to considering the human relationship, the optimal object position, and the rationality of components, so as to ensure comfortable operation and convenient maintenance.

[0005] When detecting the cut paper, if there are paper scraps or dust on the paper, when the paper with paper scraps or dust passes through the camera, the camera will mistake the paper scraps or dust for stains, thus misidentifying this part of the paper as an unqualified product and rejecting it, thereby reducing the accuracy of paper detection.

Detailed Description of the Invention

[0053] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0054] Embodiment 1: As Figures 1 to 10 shown, a detection device for cigarette label printed matter according to the present invention includes an inspection machine, and the inspection machine is controlled by a control system; the inspection machine includes a paper feeding part, a detection part and a discharging part; the detection part scans the printed paper passing through by means of a computer graphic recognition system;

[0055] The detection part includes a detection bin 1; one or more light sources are installed in the detection bin 1; a high-speed camera 11 is installed in the middle of the light source;

[0056] A conveyor belt 12 is arranged below the detection bin 1; baffles 13 are arranged on both sides of the conveyor belt 12, and the conveyor belt 12 rotates on the two baffles 13 and is driven by a first motor 14; a base 15 is arranged below the baffle 13;

[0057] A cleaning bin 2 is arranged on the left side of the detection bin 1; a bin door 21 is installed on the top of the cleaning bin 2; two first cleaning mechanisms 22 and one second cleaning mechanism 23 are arranged in the cleaning bin 2;

[0058] The two first cleaning mechanisms 22 are arranged above the conveyor belt 12 and are mirror-symmetrically arranged with the midline of the conveyor belt 12 as the dividing line; the two first cleaning mechanisms 22 include first pressing blocks 24;

[0059] Uniformly arranged rollers 25 are rotatably connected to the bottoms of the two first pressing blocks 24, and a driving belt 26 is rotatably connected to the plurality of rollers 25 together, and the driving belt 26 is attached to the conveyor belt 12; uniformly arranged leakage grooves 121 are formed in the conveyor belt 12, and adjacent leakage grooves 121 are arranged in a staggered manner;

[0060] Mounting plates 27 are arranged on the opposite sides of the two first pressing blocks 24, and the mounting plates 27 are arranged on the side walls of the cleaning bin 2; cleaning components are arranged between the two first pressing blocks 24 and the mounting plates 27;

[0061] The second cleaning mechanism 23 includes two second pressing blocks 28, and the two second pressing blocks 28 are located on the opposite sides of the two first pressing blocks 24, and part of the two first pressing blocks 24 extends into the space between the two second pressing blocks 28;

[0062] Uniformly arranged rollers 25 are also rotatably connected to the bottoms of the second pressing blocks 28, and a driving belt 26 is rotatably connected to the plurality of rollers 25 together; a cleaning component is also arranged between the two second pressing blocks 28, and the cleaning component is used for cleaning the passing paper;

[0063] Both the top of the first pressing block 24 and the second pressing block 28 are fixedly connected with two connecting plates 3; four supporting plates 31 are installed below the door 21; the connecting plates 3 are all installed on the opposite supporting plates 31;

[0064] In this embodiment, the cleaning assembly includes two rotating rods 4;

[0065] The two rotating rods 4 in the first cleaning mechanism 22 rotate between the first pressing block 24 and the mounting plate 27; the two rotating rods 4 in the second cleaning mechanism 23 rotate between the two second pressing blocks 28;

[0066] Second motors 41 are installed inside both the first pressing block 24 and the second pressing block 28, and the second motors 41 are used to drive the rotating rods 4 to rotate;

[0067] Both sides of each rotating rod 4 are fixedly connected with belt pulleys 42; the two belt pulleys 42 on the same side are jointly rotatably connected with a belt 43, and the two belts 43 in each cleaning assembly correspond to each other;

[0068] Cleaning plates 5 are arranged evenly between two opposite belts 43, and the cleaning plates 5 are all fixedly connected to the two opposite belts 43; a brush 51 is fixedly connected to the side of the cleaning plate 5 away from the rotating rod 4;

[0069] Specifically, when detecting the printed paper, first start the inspection machine, then place the paper to be detected in the paper feeding part, and then the paper feeding part transfers the paper to the conveyor belt 12 in sequence. At the same time, the first motor 14 drives the conveyor belt 12 to rotate clockwise, which will drive the paper to move. Since the conveyor belt 12 is in contact with the driving belt 26 below the first pressing block 24 and the second pressing block 28, it will drive the driving belt 26 and the roller 25 to rotate. When the paper moves to the first cleaning mechanism 22, at this time the paper will move between the driving belt 26 below the two first pressing blocks 24 and the conveyor belt 12. Then the paper will continue to move along with the conveyor belt 12 under the pressing of the two driving belts 26 below the two first pressing blocks 24. At the same time, when the conveyor belt 12 rotates, control the second motor 41 to rotate. The second motor 41 will drive the rotating rod 4 to rotate, and at the same time the rotating rod 4 will drive the belt 43 to rotate clockwise through the belt pulley 42. When the belt 43 rotates, it will drive the cleaning plates 5 in the two first cleaning mechanisms 22 to rotate, and the cleaning plates 5 will drive the brushes 51 to rotate. The clockwise rotating brushes 51 just pass above the paper passing through the first cleaning mechanism 22, so as to clean the upper surface of the paper. At the same time, since the middle position of the paper is limited on the driving belt 26 below the two first pressing blocks 24, it is possible to clean both sides of the paper while the middle of the paper is being pressed, so as to sweep off the dust or paper scraps on both sides of the paper;

[0070] More specifically, since the first pressing block 24 partially extends between the two second pressing blocks 28, when the paper moves to the end position of the first pressing block 24 following the conveyor belt 12, the end portions on both sides of the paper will move under the driving belt 26 below the two second pressing blocks 28. At this time, the driving belt 26 below the second pressing blocks 28 will press the positions on both sides of the paper. Subsequently, the paper will continue to move following the conveyor belt 12. At the same time, the belt 43 between the two second pressing blocks 28 also rotates clockwise, and will drive the cleaning plate 5 and the brush 51 on the cleaning plate 5 to rotate. Since both sides of the paper are limited on the driving belt 26 below the second pressing blocks 28, the middle position of the paper can be cleaned while the two sides of the paper are pressed, so that the paper scraps or dust at the middle position of the paper can be swept away. When the paper passes through the second cleaning mechanism 23, it will move to the detection bin 1 following the conveyor belt 12;

[0071] Furthermore, when the paper enters the detection bin 1, the light source in the cleaning bin 2 will irradiate the paper at this time. Subsequently, the high-speed camera 11 will scan the pattern on the passing paper and identify it through the computer graphic system. If there are defects in the pattern on some papers, when the paper moves to the discharging part, it will be discharged by the discharging part, and at the same time, the qualified papers will be collected;

[0072] Even further, by using the first cleaning mechanism 22 to clean both sides of the paper while pressing the middle part of the paper, and then using the second cleaning mechanism 23 to clean the middle position of the paper while pressing both sides of the paper, the two sides and the middle of the paper can be comprehensively cleaned in sequence, so that the paper scraps or dust on the paper can be swept off the paper. When there are paper scraps or dust on the paper, the high-speed camera 11 will mistake the paper scraps or dust for stains, and thus will mistake this part of the paper for an unqualified product and reject it, which will reduce the accuracy of paper detection.

[0073] Embodiment 2: The cleaning plate 5 includes a U-shaped plate 52 and a long plate 53; a slideway is provided on the inner circumferential surface of the U-shaped plate 52;

[0074] Sliders 54 are fixedly connected to both sides of the long plate 53, and the long plate 53 slides in the slideway inside the U-shaped plate 52 through the sliders 54; Brushes 51 are fixedly connected to the bottoms of both the U-shaped plate 52 and the long plate 53; The U-shaped plate 52 and the long plate 53 are respectively fixedly connected to two opposite belts 43;

[0075] On one side of the mounting plate 27 close to the cleaning bin 2, a first chute 32 is provided on the inner wall of the cleaning bin 2, and the mounting plate 27 slides in the first chute 32;

[0076] A loop-shaped plate 33 is fixedly connected to the top of each of the connecting plates 3, and the loop-shaped plates 33 are all slidably mounted on the upper support plates 31 and fixed by locking bolts 34;

[0077] The rotating rod 4 includes two fixed cylinders 401 and a rectangular rod 402, and a rectangular groove is formed in the fixed cylinder 401; the two fixed cylinders 401 in the first cleaning mechanism 22 are respectively rotatably mounted on the first pressing block 24 and the mounting plate 27, and the rectangular rod 402 is slidably mounted in the rectangular grooves of the two opposite fixed cylinders 401;

[0078] The two fixed cylinders 401 in the second cleaning mechanism 23 are respectively rotatably mounted on the two second pressing blocks 28, and the rectangular rod 402 is slidably mounted in the rectangular grooves of the two opposite fixed cylinders 401;

[0079] In this embodiment, on the side of the two support plates 31 of the first cleaning mechanism 22 and the second cleaning mechanism 23 close to the cleaning bin 2, a second sliding groove 35 is formed in the inner wall of the cleaning bin 2, and the two support plates 31 of the first cleaning mechanism 22 and the second cleaning mechanism 23 are respectively slidably mounted in the opposite second sliding grooves 35;

[0080] Two threaded rods 36 are rotatably connected to the bottom of the second sliding groove 35, and the threaded rods 36 pass through the upper support plates 31 and are threadedly engaged with the support plates 31;

[0081] Specifically, when it is necessary to detect papers of different lengths, first open the bin door 21, and then adjust the distance between the first pressing block 24 and the second pressing block 28 according to the length of the paper. When adjusting the distance between the two first pressing blocks 24, first loosen the locking bolt 34 on the loop-shaped plate 33 above the connecting plate 3 of the first pressing block 24, and then pull the two first pressing blocks 24 away from or close to each other according to the length of the paper. At the same time, the two first pressing blocks 24 will drive the loop-shaped plate 33 to move away from or close to each other along the support plate 31 through the connecting plate 3. When the two first pressing blocks 24 reach the appropriate positions, then use the locking bolt 34 to lock the moved loop-shaped plate 33;

[0082] More specifically, when adjusting the distance between the two second pressing blocks 28 before, loosen the locking bolt 34 on the return plate 33 above the second pressing block 28, and then push the two second pressing blocks 28 away from or close to each other. When the paper is under the two second pressing blocks 28, then use the locking bolt 34 to lock the return plate 33 again. Whether adjusting the distance between the two first pressing blocks 24 or the second pressing blocks 28, when the two first pressing blocks 24 or the second pressing blocks 28 approach or move away from each other, they will drive the U-shaped plate 52 and the long plate 53 to move away from or close to each other through the belt 43. During the process of the U-shaped plate 52 and the long plate 53 moving away from or close to each other, the long plate 53 will slide in the chute inside the U-shaped plate 52 through the slider 54 to adapt to the distance between the two belts 43; at the same time, during the process of the two first pressing blocks 24 or the second pressing blocks 28 moving away from or close to each other, the two opposite fixed cylinders 401 will be driven to move away from or close to each other. Since the rectangular rod 402 slides in the rectangular grooves inside the two fixed cylinders 401, when the two opposite fixed cylinders 401 move away, at this time the rectangular rod 402 gradually extends out of the two fixed cylinders 401, and when the two opposite fixed cylinders 401 approach, the rectangular rod 402 will gradually slide into the two fixed cylinders 401;

[0083] Further, when it is necessary to detect papers of different thicknesses, first open the bin door 21, and then rotate the threaded rod 36 in sequence. When the threaded rod 36 rotates, it will drive the support plate 31 to move upward or downward, so as to adjust the distance between the first cleaning mechanism 22 and the second cleaning mechanism 23 and the conveyor belt 12. At the same time, the mounting plate 27 will move upward or downward in the first chute 32, and the support plate 31 will move upward or downward in the second chute 35;

[0084] Furthermore, by adjusting the distance between the two first pressing blocks 24 according to the length of the paper, the two first pressing blocks 24 can press both sides of the middle position of the paper, avoiding the situation that the two first pressing blocks 24 only press the middle position of the paper, which may cause the two sides of the paper to warp. By adjusting the distance between the two second pressing blocks 28, the sides of papers of different lengths can be pressed, so that the first cleaning mechanism 22 and the second cleaning mechanism 23 can clean papers of different lengths. At the same time, the distance between the first cleaning mechanism 22 and the second cleaning mechanism 23 and the conveyor belt 12 can be adjusted according to the thickness of the paper, so that papers of different thicknesses can be cleaned, thereby improving the practicability of the inspection machine.

[0085] Embodiment 3: Below the first cleaning mechanism 22 and the second cleaning mechanism 23, a collection assembly is provided inside the inner circle of the conveyor belt 12;

[0086] The collection component includes a first collection bin 6; the first collection bin 6 is arranged inside the inner circle of the conveyor belt 12 and fixedly connected to two baffles 13; a uniformly arranged first suction pipe 61 is provided inside the first collection bin 6, and the first suction pipe 61 passes through the baffle 13 and extends to the outside, and the first suction pipe 61 extending to the outside is communicated with an external vacuum cleaner;

[0087] Specifically, when the rotating brush 51 cleans the paper, at this time, the gas inside the first collection bin 6 is extracted by the first suction pipe 61. At the same time, the first cleaning bin 2 will extract the gas below the first cleaning mechanism 22 and the second cleaning mechanism 23 through the uniformly arranged leakage grooves 121. After the brush 51 sweeps the paper scraps or dust from the paper, the brush 51 will continue to push the paper scraps and dust to move. When the paper scraps and dust move to the position of the leakage groove 121, at this time, the paper scraps and dust will fall into the leakage groove 121, and the sucked gas will also drive the paper scraps and dust into the first collection bin 6. Subsequently, the paper scraps and dust entering the first collection bin 6 will enter the vacuum cleaner through the first suction pipe 61. In this process, it can be avoided that the paper scraps and dust swept by the brush 51 continue to remain on the conveyor belt 12, resulting in the paper scraps and dust remaining on the conveyor belt 12 adhering to the subsequent paper again. At the same time, when the first collection bin 6 extracts the gas above the conveyor belt 12, the paper can be adsorbed, so that the paper can be adsorbed on the conveyor belt 12, thereby further fixing the paper.

[0088] Embodiment 4: A driven belt 7 is provided at the bottom of the first collection bin 6, and the driven belt 7 rotates on two baffles 13 through a rotating shaft;

[0089] The driven belt 7 is in contact with the inner circumferential surface of the conveyor belt 12; uniformly arranged rubber strips 71 are fixedly connected to the outer circumferential surface of the conveyor belt 12, and adjacent rubber strips 71 are arranged in a staggered manner. When the conveyor belt 12 passes below the driven belt 7, the rubber strips 71 will be inserted into the leakage grooves 121;

[0090] In this embodiment, a second collection bin 72 is provided below the driven belt 7, and the second collection bin 72 is fixedly connected to two baffles 13;

[0091] Uniformly arranged second suction pipes 73 are fixedly connected to the bottom of the second collection bin 72, and the second suction pipes 73 are communicated with an external vacuum cleaner; the conveyor belt 12 passes between the second collection bin 72 and the driven belt 7;

[0092] In this embodiment, an arc-shaped plate 74 is fixedly connected to the left side of each second suction pipe 73, and the arc-shaped plates 74 are all in contact with the conveyor belt 12;

[0093] Specifically, when the conveyor belt 12 rotates, it drives the driven belt 7 to rotate. The rotating driven belt 7 drives the uniformly arranged rubber strips 71 to rotate. When the leakage slots 121 on the conveyor belt 12 pass by the rubber strips 71, the rubber strips 71 will insert into the leakage slots 121. During the insertion into the leakage slots 121, the paper scraps and dust adhering to the inside of the leakage slots 121 can be pushed out. The pushed-out paper scraps and dust will fall into the second collection bin 72, thereby avoiding the residual paper scraps and dust in the leakage slots 121, which may cause this part of the paper scraps and dust to adhere to the paper again;

[0094] More specifically, the second suction pipe 73 can extract the gas in the second collection bin 72. After the paper scraps and dust fall into the inside of the second collection bin 72, the second suction pipe 73 can extract the paper scraps and dust, thereby avoiding the accumulation of paper scraps and dust in the second collection bin 72. At the same time, since the arc-shaped plate 74 is in contact with the conveyor belt 12, when the conveyor belt 12 rotates, the arc-shaped plate 74 can scrape the surface of the conveyor belt 12, thereby scraping the paper scraps and dust on the surface of the conveyor belt 12 into the second collection bin 72. During this process, the amount of paper scraps and dust on the conveyor belt 12 can be further reduced, avoiding this part of the paper scraps and dust from adhering to the paper again.
