Description

Technical Field

[0001] The present invention belongs to the technical field of printed matter quality detection, and in particular relates to a cigarette label printed matter quality detection device with a double-sided detection function. Background Art

[0002] Background technology for quality inspection of printed cigarette labels involves the high standards for printing quality of cigarette labels in the tobacco industry. As a key packaging element of tobacco products, cigarette labels not only need to meet the requirements of beautiful and clear visual effects, but also need to ensure the accurate restoration of patterns, texts and colors. With the continuous development of printing technology, traditional manual inspection methods have been unable to meet the requirements of high precision and high efficiency in large-scale production. Therefore, automated detection devices based on image processing and computer vision technology have emerged. These devices can quickly detect various defects in the printing process, such as color difference, alignment error and blur, by capturing cigarette label images in real time and performing intelligent analysis, to ensure that the printing quality of each cigarette label meets industry standards.

[0003] With the changes in market demand and new designs, the quality of cigarette label printing directly affects consumers' brand awareness and product image. The existing cigarette label printing quality inspection device usually adopts a single-sided inspection method when working, resulting in the need for a separate device to inspect the other side of the cigarette label. At the same time, unqualified cigarette label printing products cannot be quickly distinguished, and the cost is significantly increased, but the quality cannot be improved. In addition, the positions of cigarette labels of different brands are different, resulting in the need for different equipment for quality inspection, which increases production costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a cigarette label printed material quality detection device with a double-sided detection function.

[0005] The technical solution adopted to solve the above technical problems is: a cigarette label printed material quality inspection device with double-sided inspection function, including an inspection platform, a conveying mechanism installed on the top of the inspection platform, a plurality of cigarette boxes are transported on the top of the conveying mechanism, and a marking mechanism is installed on the sides of the plurality of cigarette boxes for controlling the placement of the cigarette boxes on the conveying mechanism; The alignment mechanism includes two alignment rods, each of which has a through slot in its inner wall, and a vertical conveyor belt rotatably connected to the inside of each through slot. The two alignment rods drive the corresponding vertical conveyor belt to move close to the side of the cigarette box for alignment transmission; A flipping mechanism is installed at the middle end of the conveying mechanism away from the marking mechanism, for flipping the cigarette box for double-sided inspection; The flip mechanism includes a flip body, the outer wall of which is provided with a plurality of placement grooves, and the inside of the flip body is provided with a fitting groove at the middle end of the corresponding placement groove, the placement groove supports the surface of the cigarette box and the side surface is located inside the fitting groove.

[0006] A main body is installed at the bottom of the detection platform, and a display console is installed on the side of the main body surface away from the flip mechanism.

[0007] Furthermore, the conveying mechanism includes two first fixed plates, a plurality of rotating shafts are rotatably connected between the two first fixed plates, a plurality of horizontal transmission wheels are fixedly connected to the outer walls of the plurality of rotating shafts, a plurality of horizontal transmission wheels are rotatably connected to the outer walls of the plurality of horizontal transmission wheels, two rectangular grooves are provided inside the two first fixed plates, and the two first fixed plates are provided with an arc-shaped opening for providing rotation of the flip body, one of the first fixed plates is installed with a first motor on both sides away from the arc-shaped opening, a horizontal conveyor belt is installed inside each of the rectangular grooves to drive the two horizontal transmission wheels to rotate, and the corresponding rotating shaft is driven by the first motor to drive the corresponding horizontal transmission wheel to rotate and transport the cigarette box.

[0008] Through the above technical solution, when in use, when preparing to inspect the cigarette labels on the cigarette boxes, the conveying mechanism can be used to first transport the uninspected cigarette boxes. After the cigarette box inspection is completed and the unqualified ones are removed, the conveying mechanism can be used again to transport the qualified ones, thereby realizing assembly line inspection and improving the inspection speed. Specifically, the cigarette boxes are placed on top of multiple horizontal conveyor belts, and then the first motor is started to drive the corresponding rotating shaft to rotate, and then drive the multiple horizontal conveyor wheels to rotate, so that the multiple horizontal conveyor belts can transport the cigarette boxes and wait for inspection.

[0009] Furthermore, the bottom of the two benchmark rods is threadedly connected to a threaded shaft on one side away from the corresponding first fixed plate, and the bottom of the two benchmark rods is slidably connected to guide rods on both sides of the threaded shaft. The two guide rods are fixedly connected to a second fixed plate at one end away from the corresponding first fixed plate, and a second motor is fixed on the surface of the second fixed plate to drive the threaded shaft to rotate. The inner walls of the two vertical conveyor belts are rotatably connected to two vertical conveying wheels, and the inner walls of the four vertical conveying wheels are fixedly connected to the first driving shaft. A third motor is installed on the top of the two benchmark rods away from the flip body. The two third motors drive the first driving shaft to drive the vertical conveying wheel to rotate, and the second motor drives the threaded shaft to drive the two benchmark rods to move synchronously on the guide rods.

[0010] Through the above technical solution, before the cigarette boxes are processed, they can be selected according to the positions of cigarette labels of different brands to ensure that the cigarette labels can be fully detected. While ensuring the detection quality, the working performance of the cigarette label detection device is improved. Specifically, when the cigarette boxes are placed on multiple horizontal conveyor belts, the second motor can be started to drive the threaded shaft to rotate. Under the stability of the two guide rods, the two alignment rods move synchronously, so that the cigarette labels on the cigarette boxes can be accurately aligned with the detection position to ensure the detection effect. Subsequently, the two third motors are started to drive the vertical conveyor wheels on the first drive shaft to rotate, so that the vertical conveyor belt can fit the shorter side of the cigarette box to avoid the cigarette box from turning sideways during transportation and changing the position of the cigarette labels, thereby improving the detection quality of the cigarette boxes.

[0011] Furthermore, a detection mechanism is installed on the top of the detection platform away from the flipping mechanism. The detection mechanism includes an imaging system. An optical marker for detecting color is installed on the top of the imaging system, and the outer wall of the optical marker is fixedly connected to a mirror reflection device surrounding the imaging system. The optical marker connecting frame is located on the top of the flipping body and a probe is installed. Two data cables are installed on the top of the optical marker, and hydraulic cylinders are installed on the output ends of the two data cables. After the imaging system detects the cigarette labels on the cigarette box, the data is transmitted to the hydraulic cylinder by the cables for quality identification. The outer wall connecting frame of the optical marker is fixedly connected to a fixed platform. The top of the detection platform is fixedly connected to a base frame away from the flipping mechanism. The top of the base frame is fixedly connected to a movable groove. A threaded rod for moving the fixed platform is rotatably connected inside the movable groove. The movable groove is fixedly connected to a fourth motor on the side away from the fixed platform for driving the threaded rod to rotate.

[0012] Through the above technical solution, when the cigarette box is transported to the position to be inspected, the inspection mechanism is used to inspect the cigarette label, and other mechanisms are used to eliminate the cigarette box, so that the unqualified front and back of the cigarette box can be classified, and the problem can be quickly located. Specifically, when the cigarette box is transported to the position to be inspected, under the guidance of the automatic positioner, the imaging system in the existing technology is used to use multiple cameras to shoot samples from different angles to obtain data in more dimensions and conduct more comprehensive defect detection. At the same time, the optical mark separator is used to accurately detect whether the color of the cigarette label meets the standard. The data is then transmitted to the display console for judgment through a hidden transmission line. When a defective cigarette label is detected, the information will be transmitted to the corresponding hydraulic cylinder through one of the data lines to push the cigarette box and separate it. On the contrary, if it is qualified, the cigarette box will be flipped over. As the cigarette box moves, the fourth motor is started to drive the threaded rod to rotate and drive the fixed platform to move, and then the detection equipment moves to the next place to inspect the other side of the cigarette box. It should be understood that if necessary, three-sided inspection can be performed when the cigarette box reaches the top.

[0013] Furthermore, a second drive shaft is fixedly connected to the inside of the flipping body, and the second drive shaft is fixedly connected to a fifth motor at one end away from the fitting groove, and drives the second drive shaft to drive the flipping body to rotate. The two ends of the second drive shaft are rotatably connected to support plates, and the detection platform is away from one end of the flipping body and is fixedly connected to material chutes on both sides of the support plate, and the two material chutes are aligned with the corresponding placement grooves respectively.

[0014] Through the above technical solution, when the cigarette box is transported to the inspection position, the flipping mechanism can be used to flip the cigarette box. When the cigarette box reaches the top, the third side can be inspected. At the same time, the cigarette box can be quickly inspected in conjunction with the inspection mechanism, and the defective items on the front and back of the cigarette box can be classified. While being better organized, it can effectively locate the weak parts in the production process and avoid repeated rework. Specifically, after the cigarette box is transported to the placement slot by multiple horizontal conveyor belts, the side of the cigarette box will contact the fitting slot. It should be understood that different cigarette boxes will move when determining the cigarette labels, and then the fitting slot ensures the stability of different cigarette boxes when flipping. After the cigarette box inspection is completed, the fifth motor is started to drive the flipping body on the second drive shaft to rotate. When the cigarette box is flipped to the other side, the other side is inspected at this time. Unqualified ones will be eliminated and qualified ones will be transported to the next step.

[0015] The beneficial effects of the present invention are as follows: (1) By designing a conveying mechanism, a calibration mechanism, a detection mechanism and a flipping mechanism, the present invention can select and perform calibration detection according to cigarette labels in cigarette boxes of different brands when the quality inspection of cigarette label printing is carried out, thereby improving the applicability of the quality inspection device, and at the same time, can inspect cigarette labels on both sides of the cigarette box, and classify unqualified products according to different sides, so as to more accurately locate the problem; (2) By designing a conveying mechanism and a calibration mechanism, the present invention first determines the position of cigarette labels in cigarette boxes of different brands when inspecting cigarette labels, so that the cigarette labels can be accurately aligned with the inspection position, thereby improving the applicability of the inspection device, and at the same time adopts a front and rear conveying mechanism, which can form an assembly line after the cigarette boxes are quality inspected, thereby improving production efficiency; (3) By designing a detection mechanism and a flipping mechanism, the present invention can realize double-sided inspection during the cigarette box inspection process, and classify unqualified products on both sides, thereby being able to take different treatment measures according to the unqualified categories, and at the same time locate the weak parts in the production link to avoid repeated rework.

After the inspection of the cigarette boxes 13 is completed and the unqualified ones are removed, the conveying mechanism 2 is used again to transport the qualified ones, thereby realizing assembly line inspection and improving the inspection speed. Specifically, the cigarette boxes 13 are placed on the top of multiple horizontal conveyor belts 26, and then the first motor 22 is started to drive the corresponding rotating shaft 23 to rotate, and then drive the multiple horizontal conveyor wheels 24 to rotate, and then the multiple horizontal conveyor belts 26 can transport the cigarette boxes 13 and wait for inspection.

Two third motors 37 drive the first drive shaft 38 to drive the vertical transmission wheel 39 to rotate, and the second motor 32 drives the threaded shaft 33 to drive the two alignment rods 35 to move synchronously on the guide rod 34. Before processing the cigarette box 13, it can be selected according to the position of the cigarette label of different brands to ensure that the cigarette label can be fully detected. While ensuring the detection quality, the working performance of the cigarette label detection device is improved. Specifically, when the cigarette box 13 is placed on multiple horizontal conveyor belts 26, the second motor 32 can be started to drive the threaded shaft 33 to rotate. Under the stability of the two guide rods 34, the two alignment rods 35 move synchronously, so that the cigarette label on the cigarette box 13 can be accurately aligned with the detection position to ensure the detection effect. Then, the two third motors 37 are started to drive the vertical transmission wheel 39 on the first drive shaft 38 to rotate, so that the vertical conveyor belt 310 can fit the shorter side of the cigarette box 13 to avoid the cigarette box 13 from tilting sideways during transportation and changing the position of the cigarette label, thereby improving the detection quality of the cigarette box 13.

The top of the detection platform 12 is fixedly connected to the end away from the flip mechanism 5. The top of the bottom frame 41 is fixedly connected to the moving groove 42. The threaded rod 44 for moving the fixed platform 45 is rotatably connected inside the moving groove 42. The side of the moving groove 42 away from the fixed platform 45 is fixedly connected to the fourth motor 43 for driving the threaded rod 44 to rotate. When the cigarette box 13 is transported to the position to be detected, the detection machine is used to detect the cigarette box 13. The structure 4 detects the cigarette labels and cooperates with other mechanisms to remove the cigarette boxes 13, so that the unqualified front and back of the cigarette boxes 13 can be classified, and the problem can be quickly located. Specifically, when the cigarette box 13 is transported to the position to be inspected, under the guidance of the automatic positioner 47, the imaging system 49 in the prior art uses multiple cameras to shoot samples from different angles to obtain data of more dimensions and perform more comprehensive defect detection. At the same time, it cooperates with the optical mark divider 46 to accurately detect whether the color of the cigarette label meets the standard. Then the data is hidden. The information is transmitted to the display console 14 through a hidden transmission line for judgment.

It should be understood that if necessary, three-sided detection can be carried out when the cigarette box 13 reaches the top.

[0022] like Figure 6-Figure 8As shown, a flipping mechanism 5 is installed at the middle end of the conveying mechanism 2 away from the marking mechanism 3, which is used to flip the cigarette box 13 for double-sided inspection. The flipping mechanism 5 includes a flipping body 54, and a plurality of placement grooves 56 are opened on the outer wall of the flipping body 54. A fitting groove 55 is opened at the middle end of the corresponding placement groove 56 inside the flipping body 54.

When the cigarette box 13 reaches the top, the third side can be inspected. At the same time, the detection mechanism 4 can be used to quickly inspect the cigarette box 13 and classify the defective items on the front and back of the cigarette box 13. While better organizing, it can effectively locate the weak parts in the production process and avoid repeated rework. Specifically, after the cigarette box 13 is conveyed to the placement groove 56 by multiple horizontal conveyor belts 26, the side of the cigarette box 13 will contact the fitting groove 55. It should be understood that different cigarette boxes 13 will move when determining the cigarette labels, and then the fitting groove 55 ensures the stability of different cigarette boxes 13 when flipping. After the inspection of the cigarette box 13 is completed, the fifth motor 52 is started to drive the flip body 54 on the second drive shaft 53 to rotate. When the cigarette box 13 is flipped to the other side, the other side is inspected at this time. Unqualified ones will be rejected and qualified ones will be transported to the next step.

Under the stability of the two guide rods 34, the two alignment rods 35 move synchronously, so that the cigarette label on the cigarette box 13 can be accurately aligned with the detection position to ensure the detection effect. Then, the two third motors 37 are started to drive the vertical transmission wheel 39 on the first drive shaft 38 to rotate, and the first motor 22 is started to drive the corresponding rotating shaft 23 to rotate, and then the multiple horizontal transmission wheels 24 are driven to rotate, so that the multiple horizontal conveyor belts 26 can transport the cigarette box 13. When the cigarette box 13 is transported to the position to be detected, under the guidance of the automatic positioner 47, the imaging system 49 in the prior art is used to use multiple cameras from different angles. Photograph the samples to obtain data in more dimensions and conduct more comprehensive defect detection. At the same time, cooperate with the optical marker 46 to accurately detect whether the color of the cigarette label meets the standard. The data is then transmitted to the display console 14 through a hidden transmission line for judgment. When a defective cigarette label is detected, the information will be transmitted to the corresponding hydraulic cylinder 411 through one of the data lines 410 to push the cigarette box 13 so that it slides from one of the material chutes 57. The side of the qualified cigarette box 13 will contact the fitting groove 55, and the fifth motor 52 will be started to drive the flip body 54 on the second drive shaft 53 to rotate. When the cigarette box 13 is flipped to the other side, the other side will be detected. If it is unqualified, repeat the above steps. If both sides are qualified, they will be transmitted to the next step from multiple horizontal transmission wheels 24 on the other side. At this point, the cigarette label quality inspection process is completed.
