Description

Technical Field

[0001] The invention belongs to the technical field of automated equipment and relates to a new paper tube external inspection machine. Background Art

[0002] During the paper tube production process, surface defects such as dents, pits, and scratches are common, seriously affecting the quality and performance of the paper tubes. Existing inspection methods mainly rely on manual visual inspection, which is not only inefficient and labor-intensive, but also has detection accuracy significantly affected by human factors, making it difficult to detect minor defects. Some automated inspection equipment has problems such as a single detection angle, inaccurate positioning, and a low degree of automation. It is unable to achieve comprehensive and accurate detection of paper tube surface defects, making it difficult to meet the product quality control needs of modern paper tube manufacturers. Therefore, there is an urgent need to develop a paper tube external inspection machine that can overcome the above defects.

[0003] To overcome the shortcomings of the existing technology, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a paper tube anomaly detection mechanism for a tube reel [Application Number: 201920861206.1]. The mechanism includes a base, a machine table on the base, and a cutter that can reciprocate along the paper tube conveying direction above the machine table. The machine table is slidably arranged with the base. The mechanism also includes a tension sensor, a first pull rod, and a second pull rod. One end of the first pull rod is fixedly connected to the machine table, and the end of the first pull rod away from the machine table is fixedly connected to the tension sensor. One end of the second pull rod is connected to a cutting die, and the other end of the second pull rod is connected to the tension sensor. The cutting die is placed on the machine table and moves under the traction of the second pull rod. However, during the detection process, this solution still cannot achieve comprehensive and accurate detection of paper tube surface defects and has the disadvantage of low efficiency.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown, a new paper tube external inspection machine includes a chassis frame 1, and the chassis frame 1 has an electric control installation space 2 and a detection space 3. The detection space 3 is located below the electric control installation space 2, and the electric control installation space 2 is provided with an electric control component 4. The left and right ends of the detection space 3 are provided with a feed port 5 and a discharge port 6. The detection space 3 is equipped with an automatic mesh belt conveyor mechanism 7 for paper tubes, one end of which extends to the outside of the feed port 5 and the other end extends to the outside of the discharge port 6. The detection space 3 is also provided with a surface light type multi-angle defect detection device 8 for detecting surface defects of the paper tube 100. The surface light type multi-angle defect detection device 8 corresponds to the position of the paper tube automatic mesh belt conveyor mechanism 7, and a paper tube positioning component 9 is provided between the surface light type multi-angle defect detection device 8 and the paper tube automatic mesh belt conveyor mechanism 7.

[0030] In this embodiment, the new paper tube external inspection machine uses a chassis frame 1 as the main supporting structure, and its internal space is divided into two layers, the upper layer is the electric control placement space 2, and the lower layer is the detection space 3. This layered design makes the control unit and the detection unit independent of each other, reduces electromagnetic interference, and improves the stability of equipment operation. The left and right ends of the detection space 3 are respectively provided with a feed port 5 and a discharge port 6 as the entry and exit channels of the paper tube 100. The automatic mesh belt conveying mechanism 7 for paper tubes runs through the entire detection space 3, one end of which extends to the outside of the feed port 5, and the other end extends to the outside of the discharge port 6. When the equipment is started, the motor 27 drives the mesh belt chain 26 to operate, and the paper tubes 100 placed on the feed port 5 are transported to the inspection port 100 in turn. The detection is carried out in the detection space 3, and the paper is output from the discharge port 6 after the detection is completed. The surface light type multi-angle defect detection device 8 is installed in the detection space 3, corresponding to the position of the paper tube automatic mesh belt conveyor mechanism 7, to ensure that the paper tube can pass through the detection area during the transportation process. The paper tube positioning component 9 is arranged between the surface light type multi-angle defect detection device 8 and the paper tube automatic mesh belt conveyor mechanism 7 to position the paper tube during the transportation process to ensure that the paper tube is in the best detection position. The electronic control system and the detection system are arranged in layers, combined with the automatic transportation and positioning design, to realize the full process automation control of paper tube detection, which greatly improves the detection efficiency and degree of automation compared with traditional manual detection and simple mechanical detection equipment.

[0031] Combine Figure 1-5 As shown, the surface light type multi-angle defect detection device 8 includes a plurality of vertical guide shafts 10 and transverse guide shafts 11 arranged in the detection space 3, the vertical guide shaft 10 is equipped with a camera detection component 12, and the transverse guide shaft 11 is equipped with a surface light source auxiliary component 13, the surface light source auxiliary component 13 is located above the paper tube automatic mesh belt conveyor mechanism 7, and the camera detection component 12 and the paper tube automatic mesh belt conveyor mechanism 7 are staggered.

[0032] Specifically, the surface light type multi-angle defect detection device 8 is composed of a vertical guide shaft 10, a horizontal guide shaft 11, a camera detection component 12 and a surface light source auxiliary component 13, forming a three-dimensional installation frame. The camera detection component 12 is installed on the vertical guide shaft 10 and is used to capture the surface image of the paper tube. The surface light source auxiliary component 13 is installed on the horizontal guide shaft 11 and is located above the paper tube automatic mesh belt conveyor mechanism 7. It can project uniform light onto the surface of the paper tube. The camera detection component 12 and the paper tube automatic mesh belt conveyor mechanism 7 are staggered so that multiple detection cameras 15 can capture images from different angles. The surface of the paper tube avoids detection blind spots. When the paper tube 100 is transported on the paper tube automatic mesh belt conveyor 7, the surface light source lamp group 21 first illuminates the surface of the paper tube, and then the detection camera 15 takes the paper tube image from multiple angles, and transmits the image to the electronic control board 31 for analysis, thereby realizing multi-angle detection of paper tube surface defects. Vertical and horizontal guide axes are used to construct a three-dimensional detection framework, combined with staggered camera detection components and surface light source auxiliary components, to achieve multi-angle and all-round detection of the paper tube surface, breaking through the limitations of traditional single-angle detection and significantly improving the accuracy and comprehensiveness of detection.

[0033] Combine Figure 4 、 Figure 5 As shown, the camera detection assembly 12 includes a camera mounting plate 14 and a detection camera 15 arranged on the transverse guide shaft 11 , and the camera mounting plate 14 is fixed to the vertical guide shaft 10 via a clamp connector 16 .

[0034] In this embodiment, the camera detection assembly 12 includes a camera mounting plate 14 and a detection camera 15. The camera mounting plate 14 is used to fix the detection camera 15, and it is fixed to the vertical guide shaft 10 by a clamping connector 16. The detection camera 15 is installed on the camera mounting plate 14 and can capture the surface image of the paper tube. Through the clamping connector 16, the camera mounting plate 14 can be adjusted up and down and rotated at an angle on the vertical guide shaft 10, thereby driving the detection camera 15 to adjust the shooting position and angle. This design enables the detection camera 15 to adapt to the detection requirements of paper tubes of different diameters and lengths, thereby improving the versatility of the equipment. The camera mounting plate is connected to the vertical guide shaft by a clamping connector, which realizes the flexible adjustment of the position and angle of the detection camera. Compared with fixedly installed detection cameras, it can better adapt to the detection of paper tubes of different specifications.

[0035] The clamp connector 16 includes a first fixing clamp 17, a connecting rod 18, and a first transition mounting plate 19, which are arranged between the camera mounting plate 14 and the vertical guide shaft 10. The first fixing clamp 17 is sleeved on the vertical guide shaft 10 and the two are fixed by fastening bolts. One end of the connecting rod 18 is inserted into the first fixing clamp 17, and the other end is inserted into the first transition mounting plate 19. The two ends of the connecting rod 18 are respectively fixed to the connection points of the first fixing clamp 17 and the first transition mounting plate 19 by fastening bolts. The first transition mounting plate 19 is fixed to the camera mounting plate 14.

[0036] In this embodiment, when the position and angle of the detection camera 15 need to be adjusted, the operator only needs to loosen the fastening bolts, move the camera mounting plate 14 to the appropriate position and angle, and then tighten the fastening bolts to complete the adjustment. This structural design is simple and easy to operate, and can quickly adjust the position and angle of the detection camera. The unique chuck connector structure design realizes flexible adjustment of the camera mounting plate through the combination of multiple components, providing a reliable installation foundation for multi-angle detection of the detection camera.

[0037] Combine Figure 5 As shown, the axis center line of the vertical guide shaft 10 and the axis center line of the connecting rod 18 are perpendicular to each other.

[0038] In this embodiment, the axis line of the vertical guide shaft 10 is perpendicular to the axis line of the connecting rod 18. This vertical design enables the camera mounting plate 14 to be independently adjusted in the horizontal and vertical directions. By adjusting the insertion depth and angle of the connecting rod 18 in the first fixing clamp 17 and the first transition mounting plate 19, the shooting height and tilt angle of the detection camera 15 can be precisely adjusted, thereby realizing shooting at different positions and angles on the paper tube surface. For example, when detecting paper tubes of different diameters, the shooting angle of the detection camera 15 can be adjusted to adapt to the changes in the curved surface of the paper tube by adjusting the angle of the connecting rod 18, ensuring that the image of the paper tube surface can be fully captured.

[0039] The surface light source auxiliary component 13 includes a light source mounting plate 20 arranged below the transverse guide shaft 11, a surface light source lamp group 21 is provided at the bottom of the light source mounting plate 20, and the light source mounting plate 20 is fixed to the transverse guide shaft 11 via a second transition mounting plate 22.

[0040] In this embodiment, the surface light source lamp group 21 is composed of multiple LED lamps, which can emit uniform and stable light to illuminate the surface of the paper tube. During the paper tube inspection process, the surface light source lamp group 21 is turned on under the control of the electronic control board 31, and projects light onto the surface of the paper tube, providing sufficient lighting for the detection camera 15 to shoot. Uniform lighting can avoid shadows on the surface of the paper tube, so that the detection camera 15 can clearly capture the details of the paper tube surface, thereby improving the accuracy of defect detection. The surface light source lamp group is used to provide uniform lighting, and is fixed on the horizontal guide shaft through a reasonable installation structure. In conjunction with the detection camera set at multiple angles, the problems of uneven lighting and poor detection image quality in traditional detection equipment are solved.

[0041] Combine Figure 5 As shown, the vertical guide shaft 10 and the transverse guide shaft 11 are fixed by a second fixing clamp 23 , the axis of the vertical guide shaft 10 and the axis of the transverse guide shaft 11 are perpendicular to each other, and a guide shaft fixing seat 24 is installed at the bottom of the vertical guide shaft 10 .

[0042] In this embodiment, the vertical guide shaft 10 and the transverse guide shaft 11 are fixed to each other by a second fixing clamp 23, and the axis center line of the vertical guide shaft 10 and the axis center line of the transverse guide shaft 11 are perpendicular to each other, forming a stable three-dimensional frame structure. A guide shaft fixing seat 24 is installed at the bottom of the vertical guide shaft 10, which is used to fix the entire surface light type multi-angle defect detection device 8 on the chassis frame 1.

[0043] Combine Figure 1-4 As shown, the automatic mesh belt conveying mechanism 7 for paper tubes includes a chain conveyor 25, a mesh belt chain 26 and a motor 27. A track leg 28 is provided at the bottom of the chain conveyor 25. The chain conveyor 25 passes through the detection space 3 and one end extends to the outside of the feed port 5 and the other end extends to the outside of the discharge port 6.

[0044] In this embodiment, the motor 27 is connected to the mesh belt chain 26 through a transmission device. When the motor 27 is powered on, it drives the mesh belt chain 26 to move. The surface of the mesh belt chain 26 has an anti-slip texture, which can reliably drive the paper tube 100 to move on the chain conveyor 25. After the paper tube 100 is placed on the mesh belt chain 26 from the feed port 5, as the mesh belt chain 26 runs, it passes through the paper tube positioning component 9 and the surface light multi-angle defect detection device 8 in turn, and is finally output from the discharge port 6.

[0045] Combine Figure 1-4 As shown, the paper tube positioning assembly 9 includes paper tube positioning side plates 29 arranged above both sides of the chain conveyor 25, and the paper tube positioning side plates 29 are connected to the chain conveyor 25 through a guardrail bracket 30.

[0046] In this embodiment, the paper tube positioning assembly 9 includes a paper tube positioning side plate 29 and a guardrail bracket 30. The paper tube positioning side plate 29 is arranged above both sides of the chain conveyor 25 and is connected to the chain conveyor 25 through the guardrail bracket 30. The guardrail bracket 30 adopts an adjustable structure. The distance between the paper tube positioning side plate 29 and the chain conveyor 25 can be changed by adjusting the bolts to adapt to the positioning requirements of paper tubes of different diameters. When the paper tube 100 is conveyed on the mesh belt chain 26, the paper tube positioning side plate 29 limits the paper tube from both sides to prevent the paper tube from being laterally offset or tipping over during the conveying process. In this way, the paper tube can always maintain the best shooting position of the detection camera 15 when passing through the surface light type multi-angle defect detection device 8, ensuring the accuracy and consistency of the detection results.

[0047] Combine Figure 1 As shown, the electric control assembly 4 includes an electric control board 31 arranged in the electric control placement space 2, and a display 32, an operation panel 33 and an alarm light 34 are provided on the front of the chassis frame 1.

[0048] In this embodiment, the electronic control component 4 includes an electronic control board 31, which is installed in the electronic control placement space 2. The electronic control board 31 is connected to various components of the equipment through wires to realize the control of the motor 27, the detection camera 15, the surface light source lamp group 21, etc. The display 32, the operation panel 33 and the alarm light 34 arranged on the front of the chassis frame 1 are connected to the electronic control board 31. The operator sets the detection parameters through the operation panel 33, such as the conveying speed, the shooting frequency of the detection camera, the brightness of the surface light source, etc. The display 32 displays the detection image, detection results and equipment operation status of the paper tube in real time. When the electronic control board 31 detects defects on the surface of the paper tube through the image analysis algorithm, it immediately controls the alarm light 34 to emit an audible and visual alarm to remind the operator to take action. The integrated electronic control component design realizes intelligent control and real-time monitoring of the equipment.

[0049] The working principle of the present invention is:

[0050] Paper tube loading and conveying stage: The operator places the paper tube to be tested at the feed port 5, at which point the paper tube automatic mesh belt conveyor mechanism 7 begins to operate. The motor 27 serves as a power source, driving the mesh belt chain 26 through a transmission device. Since the surface of the mesh belt chain 26 is provided with an anti-slip texture, it can be in close contact with the surface of the paper tube, generating sufficient friction, thereby driving the paper tube to move along the chain conveyor 25 toward the discharge port 6. The track legs 28 at the bottom of the chain conveyor 25 can be adjusted in height according to the actual ground conditions to ensure that the chain conveyor 25 is in a horizontal state, so that the paper tube remains stable during the conveying process. During the paper tube conveying process, the paper tube positioning assembly 9 plays a role. The paper tube positioning side plates 29 are installed above both sides of the chain conveyor 25 through the guardrail bracket 30, and the adjustment bolts of the guardrail bracket 30 can change the spacing between the paper tube positioning side plates 29. When the paper tube enters the conveying channel, the paper tube positioning side plates 29 on both sides limit the paper tube to prevent the paper tube from lateral deviation or tipping during the conveying process, ensuring that the paper tube always moves along the predetermined conveying path, preparing for subsequent accurate detection;

[0051] Defect detection stage: When the paper tube is transported to the area of ​​the surface light type multi-angle defect detection device 8 in the detection space 3, the detection process starts. First, the electronic control board 31 controls the surface light source lamp group 21 of the surface light source auxiliary component 13 to turn on. The surface light source lamp group 21 is composed of multiple LED lamps, which can project a large area of ​​uniform light onto the surface of the paper tube to ensure that all parts of the paper tube surface can be fully illuminated to avoid the shadow area affecting the detection effect. At this time, the detection camera 15 installed on the vertical guide shaft 10 starts to work. Since the camera mounting plate 14 is connected to the vertical guide shaft 10 through the clamp connector 16, and the axis of the vertical guide shaft 10 is perpendicular to the axis of the connecting rod 18, the detection camera 15 can be flexibly adjusted in the horizontal and vertical directions according to the specifications of the paper tube and the detection requirements by adjusting the fastening bolts of the clamp connector 16, and the paper tube surface can be photographed at multiple different angles. Multiple detection cameras 15 capture images of the paper tube surface from different directions to form a three-dimensional image structure. These image data are transmitted in real time to the electric control board 31 in the electric control placement space 2 via a data line;

[0052] Data Processing and Feedback Stage: The electronic control board 31, equipped with advanced image analysis algorithms, receives image data transmitted by the inspection camera 15 and first pre-processes the image, including image enhancement and noise reduction, to improve image clarity and quality. Then, using algorithms such as edge detection and feature extraction, it compares and analyzes the paper tube image with a preset standard image to determine whether there are surface defects such as dents, pits, and scratches on the paper tube, and also determines the type, location, and severity of the defect. If the inspection results indicate that the paper tube is qualified, the electronic control board 31 controls the automatic mesh belt conveyor 7 to continue operating and discharge the paper tube from the discharge port 6. If a defect is detected in the paper tube, the electronic control board 31 immediately controls the alarm light 34 on the front of the chassis frame 1 to sound an audible and visual alarm. The display 32 also highlights the defect image and related information, such as the defect location and type, to remind the operator to promptly address the problem paper tube. The operator can also adjust inspection parameters in real time through the operation panel 33, such as adjusting the inspection speed, adjusting the brightness of the surface light source, and calibrating the inspection camera angle, to optimize inspection results and ensure continued efficient and accurate operation of the equipment.
