Description

Technical Field

[0001] The invention belongs to the field of detection technology, and in particular is a cigarette label printed matter detection device. Background Art

[0002] In the process of making cigarette boxes, the prepared hard paper needs to be printed with the corresponding pattern through a printing press, and then the printed paper is cut to form the basic shape of the cigarette box, and then the inspection machine is used to detect whether there are unqualified products in the group printed on the paper;

[0003] The inspection machine is a machine that automatically inspects the printing quality of cardboard. It uses a camera and auxiliary light source, as well as a computer image recognition software system, to scan the printed image. Qualified cardboard is transported out from the paper receiving section, and unqualified cardboard is automatically transported out from the middle and lower part of the machine. This allows printing plants to completely get rid of the previous situation of relying on manual inspection, greatly improving labor productivity and product quality reliability. At the same time, it can greatly shorten the printing delivery cycle and reduce the labor cost of printing plants.

[0004] The inspection machine can effectively detect printing defects on various color images, such as stains, ink splashes, missing prints, color differences, misregistration, cut lines, wrinkles, etc. The design of the machine focuses on human relations, optimal object positions and rationality of components for comfortable operation and convenient maintenance.

[0005] When inspecting 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, and thus mistakenly regard the part of the paper as an unqualified product, and thus reject it, thereby reducing the accuracy of paper inspection.

[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0054] Embodiment 1: Figures 1 to 10 As shown, a cigarette label printed product inspection device described in 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 material discharge part; the detection part scans the printed paper through a computer image recognition system;

[0055] The detection unit includes a detection chamber 1; at least one light source is installed in the detection chamber 1; a high-speed camera 11 is installed in the middle of the light source;

[0056] A conveyor belt 12 is provided below the detection chamber 1; baffles 13 are provided 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 provided below the baffle 13;

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

[0058] The two first cleaning mechanisms 22 are arranged above the conveyor belt 12 and are arranged in a mirror image with the center line of the conveyor belt 12 as a dividing line; the two first cleaning mechanisms 22 include a first pressing block 24;

[0059] The bottom of the two first pressing blocks 24 are both provided with evenly arranged rollers 25, and a driving belt 26 is connected to the rollers 25 for common rotation, and the driving belt 26 is in contact with the conveyor belt 12; the conveyor belt 12 is provided with evenly arranged leakage grooves 121, and adjacent leakage grooves 121 are staggered;

[0060] The two first pressing blocks 24 are provided with mounting plates 27 on opposite sides thereof, and the mounting plates 27 are arranged on the side walls of the cleaning chamber 2; cleaning components are arranged between the two driving blocks 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 the two first pressing blocks 24 partially extend between the two second pressing blocks 28;

[0062] The bottom of the second pressing block 28 also has rollers 25 arranged evenly for rotation, and a driving belt 26 is connected to the rollers 25 for common rotation; a cleaning component is also provided between the two second pressing blocks 28, and the cleaning component is used to clean the passing paper;

[0063] The first pressing block 24 and the second pressing block 28 are both fixedly connected to two connecting plates 3 at the top; four supporting plates 31 are installed under the door 21; the connecting plates 3 are installed on 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] The first pressing block 24 and the second pressing block 28 are both internally installed with a second motor 41, and the second motor 41 is used to drive the rotating rod 4 to rotate;

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

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

[0069] Specifically, when inspecting the printed paper, the inspection machine is first started, and then the paper to be inspected is placed in the paper feeding unit, and then the paper feeding unit transfers the paper to the conveyor belt 12 in sequence, and at the same time the first motor 14 drives the conveyor belt 12 to rotate clockwise, thereby driving the paper to move, and since the conveyor belt 12 is in contact with the driving belt 26 under the first pressing block 24 and the second pressing block 28, the driving belt 26 and the roller 25 are driven to rotate, and when the paper moves to the first cleaning mechanism 22, the paper will move between the driving belt 26 under the two first pressing blocks 24 and the conveyor belt 12, and then the paper will continue to move with the conveyor belt 12 under the pressure of the two driving belts 26 under the two first pressing blocks 24. The second motor 41 is controlled to rotate when the conveyor belt 12 rotates, and the second motor 41 drives the rotating rod 4 to rotate. At the same time, the rotating rod 4 drives the belt 43 to rotate clockwise through the pulley 42. When the belt 43 rotates, the cleaning plates 5 in the two first cleaning mechanisms 22 are driven to rotate, and the cleaning plates 5 drive the brush 51 to rotate. The clockwise rotating brush 51 just passes over the paper passing through the first cleaning mechanism 22, so that the upper surface of the paper can be cleaned. At the same time, because the middle position of the paper is limited on the driving belt 26 under the two first pressing blocks 24, the two sides of the paper can be cleaned when the middle of the paper is pressed, so that the dust or paper scraps on both sides of the paper are swept off;

[0070] More specifically, since the first pressing block 24 partially extends between the two second pressing blocks 28, when the paper follows the conveyor belt 12 to move to the end position of the first pressing block 24, the two side ends of the paper will move to the bottom of the driving belt 26 under the two second pressing blocks 28. At this time, the driving belt 26 under the second pressing block 28 will press the two side edges of the paper, and then the paper will continue to follow the conveyor belt 12 to move, and at the same time, the belt 43 between the two second pressing blocks 28 will also rotate clockwise, and at the same time, it will drive the cleaning plate 5 and the brush 51 on the cleaning plate 5 to rotate. Since the two sides of the paper are limited on the driving belt 26 under the second pressing block 28, the middle position of the paper can be cleaned while pressing the two sides of the paper, so that the paper scraps or dust in the middle position of the paper can be swept away. After the paper passes through the second cleaning mechanism 23, it will follow the conveyor belt 12 to move into the detection chamber 1;

[0071] Furthermore, when the paper enters the inspection chamber 1, the light source in the cleaning chamber 2 will illuminate the paper, and then 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 of the paper, when the paper moves to the discharge part, it will be discharged by the discharge part, and the qualified paper will be collected;

[0072] Furthermore, by using the first cleaning mechanism 22 to press the middle of the paper, the two sides of the paper are cleaned, and then using the second cleaning mechanism 23 to press the two sides of the paper to clean the middle of the paper, the two sides and the middle of the paper can be completely cleaned in turn, so that the paper scraps or dust on the paper can be swept off the paper, avoiding the situation where the high-speed camera 11 will mistake the paper scraps or dust for stains when there are paper scraps or dust on the paper, and thus mistakenly identify this part of the paper as an unqualified product, which will be removed, reducing the accuracy of paper detection.

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

[0074] Slide blocks 54 are fixedly connected to both sides of the long board 53, and the long board 53 slides in the slideway in the U-shaped board 52 through the slide blocks 54; brushes 51 are fixedly connected to the bottom of the U-shaped board 52 and the long board 53; the U-shaped board 52 and the long board 53 are respectively fixedly connected to two opposite belts 43;

[0075] The mounting plate 27 is located on one side of the cleaning chamber 2 and is provided with a first slide groove 32 on the inner wall of the cleaning chamber 2, and the mounting plate 27 slides in the first slide groove 32;

[0076] A circular plate 33 is fixedly connected to the top of each connecting plate 3, and the circular plates 33 slide on the upper support plate 31 and are 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 opened in the fixed cylinder 401; the two fixed cylinders 401 in the first cleaning mechanism 22 rotate on the first pressing block 24 and the mounting plate 27 respectively, and the rectangular rod 402 slides 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 rotated on the two second pressing blocks 28, and the rectangular rod 402 slides in the rectangular grooves of the two opposite fixed cylinders 401;

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

[0080] The bottom of each of the second slide grooves 35 is rotatably connected to two threaded rods 36, and each of the threaded rods 36 passes through the upper support plate 31 and is threadedly engaged with the support plate 31;

[0081] Specifically, when it is necessary to detect papers of different lengths, the bin door 21 is first opened, and then the distance between the first pressing block 24 and the second pressing block 28 is adjusted according to the length of the paper. When adjusting the distance between the two first pressing blocks 24, the locking bolt 34 on the circular plate 33 above the connecting plate 3 of the first pressing block 24 is first loosened, and then the two first pressing blocks 24 are pulled away from or closer to each other according to the length of the paper. At the same time, the two first pressing blocks 24 will drive the circular plate 33 to move away from or closer to each other along the supporting plate 31 through the connecting plate 3. When the two first pressing blocks 24 reach the appropriate position, the moving circular plate 33 is locked by the locking bolt 34.

[0082] More specifically, when adjusting the distance between the two second pressing blocks 28, the locking bolt 34 on the circular plate 33 above the second pressing blocks 28 is loosened, and then the two second pressing blocks 28 are pushed away from or towards each other. When the paper is under the two second pressing blocks 28, the circular plate 33 can be locked again using the locking bolt 34. Regardless of 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 are approached or moved away from each other, the U-shaped plate 52 and the long plate 53 are driven to move away from or towards each other through the belt 43. When the U-shaped plate 52 and the long plate 53 are in relative In the process of moving away from or approaching each other, the long board 53 will slide in the slide groove in the U-shaped board 52 through the slider 54 to adapt to the distance between the two belts 43; at the same time, in the process of the two first pressing blocks 24 or the second pressing blocks 28 moving away from or approaching each other, the two relative fixed cylinders 401 will be driven to move away from or approach each other. Since the rectangular rod 402 slides in the rectangular grooves in the two fixed cylinders 401, when the two relative fixed cylinders 401 move away from each other, the rectangular rod 402 gradually extends out from the two fixed cylinders 401, and when the two relative fixed cylinders 401 move closer, the rectangular rod 402 gradually slides into the two fixed cylinders 401;

[0083] Furthermore, when it is necessary to detect paper of different thicknesses, the bin door 21 is first opened, and then the threaded rod 36 is rotated in sequence. When the threaded rod 36 rotates, the support plate 31 is driven to move upward or downward, thereby adjusting 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 moves upward or downward in the first slide groove 32, and the support plate 31 moves upward or downward in the second slide groove 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 on both sides of the middle position of the paper, avoiding the two first pressing blocks 24 only pressing the middle position of the paper, which causes the two sides of the paper to warp up. 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 practicality of the inspection machine.

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

[0086] The collecting assembly includes a first collecting bin 6; the first collecting bin 6 is arranged on the inner circle of the conveyor belt 12 and is fixedly connected to two baffles 13; the first collecting bin 6 is provided with uniformly arranged first suction pipes 61, and the first suction pipes 61 pass through the baffles 13 and extend to the outside, and the first suction pipes 61 extending to the outside are connected to an external vacuum cleaner;

[0087] Specifically, when the rotating brush 51 cleans the paper, the first suction pipe 61 is used to extract the gas in the first collecting chamber 6, and at the same time, the first cleaning chamber 2 will extract the gas under the first cleaning mechanism 22 and the second cleaning mechanism 23 through the evenly 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, the paper scraps and dust will fall into the leakage groove 121, and the gas drawn in will also drive the paper scraps and dust to move. The paper scraps and dust enter the first collecting bin 6, and then the paper scraps and dust entering the first collecting bin 6 will enter the vacuum cleaner through the first suction pipe 61. In this process, it can be prevented that the paper scraps and dust swept by the brush 51 continue to remain on the conveyor belt 12, causing the paper scraps and dust remaining on the conveyor belt 12 to adhere to the paper behind again. At the same time, when the first collecting bin 6 draws the gas above the conveyor belt 12, it can adsorb the paper, 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 collecting bin 6, and the driven belt 7 rotates on two baffles 13 via a rotating shaft;

[0089] The driven belt 7 is fitted with the inner ring surface of the conveyor belt 12; the outer ring surface of the conveyor belt 12 is fixedly connected with uniformly arranged rubber strips 71, and adjacent rubber strips 71 are staggered. When the conveyor belt 12 passes under the driven belt 7, the rubber strips 71 will be inserted into the drain groove 121;

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

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

[0092] In this embodiment, a curved plate 74 is fixedly connected to the left side of each of the second suction tubes 73, and the curved plates 74 are in contact with the conveyor belt 12;

[0093] Specifically, when the conveyor belt 12 rotates, it will drive the driven belt 7 to rotate, and the rotating driven belt 7 will drive the uniformly arranged rubber strips 71 to rotate. When the leakage groove 121 on the conveyor belt 12 passes through the rubber strips 71, the rubber strips 71 will be inserted into the leakage groove 121. During the insertion into the leakage groove 121, the paper scraps and dust adhering to the leakage groove 121 can be pushed out, and the pushed out paper scraps and dust will fall into the second collecting bin 72, thereby preventing the paper scraps and dust from remaining in the leakage groove 121, causing 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 collecting bin 72. When paper scraps and dust fall into the second collecting bin 72, the second suction pipe 73 can extract the paper scraps and dust, thereby preventing the paper scraps and dust from accumulating in the second collecting bin 72. At the same time, since the arc plate 74 is in contact with the conveyor belt 12, when the conveyor belt 12 rotates, the arc 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 collecting bin 72. In this process, the amount of paper scraps and dust on the conveyor belt 12 can be further reduced, thereby preventing these paper scraps and dust from adhering to the paper again.
