Description

TECHNICAL FIELD

[0001] The application relates to a paper box quality inspection technology field, in particular to a paper box processing damage detection sorting device. BACKGROUND

[0002] Paper boxes, as the most widely used packaging products, bear the core role of protecting internal products and facilitating handling and storage in the fields of logistics transportation, industrial production and commodity retail, and are indispensable basic packaging carriers in the modern supply chain system. According to the material difference, the paper boxes can be divided into corrugated boxes, single-layer paperboard boxes, laminated paper boxes and various types, and various specifications and models can be designed according to the size, weight and protection requirements of the packaged products, and the quality of the paper boxes directly determines the transportation safety and storage stability of the internal products in the downstream packaging link.

[0003] In the large-scale processing and production of paper boxes, quality detection is a key link to ensure product qualification. If paper boxes with problems such as damage, cracking and deformation flow into the downstream application scene, they are prone to damage in handling, stacking or transportation due to insufficient structural strength, thereby causing damage to the internal packaging products and causing economic losses to enterprises and consumers. At present, the detection of paper box damage in the industry mainly adopts traditional visual detection technology. This technology acquires paper box surface images in real time through a CCD camera, and then analyzes the pixel changes, contour integrity and color uniformity of the images relying on image recognition algorithms to determine whether the paper box has obvious damage.

[0004] However, the existing visual detection technology still has many technical defects in actual industrial application, and it is difficult to achieve comprehensive and accurate quality control, and there are three outstanding problems: During the detection and conveying of the paper box, the lower surface of the paper box is closely attached to the surface of the conveying belt, so that the bottom corner, which is a key part prone to extrusion damage during processing and handling, is completely blocked by the conveying belt, and the CCD camera cannot acquire the image of the bottom corner, forming a detection blind area, and the damage of the bottom corner will directly damage the overall support structure of the paper box and greatly weaken its protective performance; The CCD camera in the traditional visual detection device is usually installed at a fixed angle, and the shooting angle is single. For the hidden defects such as small concave, fine cracks, slight deformation of the corners and edges of the paper box, the image acquisition clarity and feature recognition degree are insufficient, and the missed detection may occur, which may cause some paper boxes with potential quality problems to flow into the market; For laminated paper boxes with special protection requirements, the existing technology can only detect the damage of the paperboard substrate itself, and cannot determine whether the surface film is damaged, such as scratching, peeling and bubbling. The integrity of the film directly affects the waterproof, stain-resistant and wear-resistant performance of the paper box, and the absence of this function leads to incomplete protection effect detection of the laminated paper box.

[0022] Further, the scanning assembly 34 comprises a shaft sleeve 341 installed at the bottom of the shell 31, a rotating shaft 342 installed at the middle of the shaft sleeve 341, a drive gear 343 and a swing rod 346 installed at the upper and lower ends of the rotating shaft 342 respectively, the drive gear 343 drives the rotating shaft 342 to rotate under the driving of the driver 33, a mounting bracket 344 installed at the bottom of the outer wall of the shaft sleeve 341, the mounting bracket 344 is U-shaped, a video recorder 345 installed at the top of the left side wall of the mounting bracket 344 and electrically connected with the controller 5, the controller 5 analyzes the image signals fed back by the video recorder 345, the video recording angle of the video recorder 345 is downwardly inclined, the video recorder 345 is different from the emission direction of the infrared laser 3412, so that the laser image extracted by the video recorder 345 is more intuitive, and a lifting rod 347 inserted at the end of the swing rod 346 away from the rotating shaft 342, the lifting rod 347 is lifted to adapt to the height change of the reinforcing rib 3410 when swinging.

[0023] Further, the scanning assembly 34 further comprises a rotating rod 348 installed at the inside bottom of the mounting bracket 344 through a bearing, first support rods 349 installed at the both ends of the outer wall of the rotating rod 348, the other ends of the first support rods 349 are installed with reinforcing ribs 3410, the reinforcing ribs 3410 are sleeved with sliding sleeves 3411, and the sliding sleeves 3411 are installed with the lifting rod 347, the lifting rod 347 is driven to do circular motion by the swing rod 346, and the reinforcing rib 3410 is swung, the rotating rod 348 is installed with an infrared laser 3412 at the middle of the outer wall, the infrared laser 3412 emits infrared laser outward, the laser hits the surface of the carton, the quality of the carton is judged according to the state of the laser, the rotating rod 348 is horizontally arranged to ensure that the infrared laser hits the surface of the carton as a horizontal straight line, which is beneficial to the capture of the video recorder 345.

[0024] The controller 5 sends a start signal to the driver 33, the motor inside the driver 33 drives the output gear to rotate, the output gear drives the drive gear 343 to rotate through meshing transmission, the drive gear 343 synchronously drives the rotating shaft 342 to rotate around the axis of the shaft sleeve 341, and further makes the swing rod 346 at the bottom end of the rotating shaft 342 do circular motion with the rotating shaft 342 as the center.

[0025] When the swing rod 346 makes a circular motion, the end thereof away from the rotating shaft 342 drives the lifting rod 347 to make a synchronous motion. Since the bottom end of the lifting rod 347 is connected with the reinforcing rib 3410 through the sliding sleeve 3411, and the reinforcing rib 3410 is fixed with the rotating rod 348 through the first supporting rod 349, the lifting rod 347 will slide up and down along the axis direction thereof to adapt to the height change of the reinforcing rib 3410 in the process of making a circular motion with the swing rod 346, and at the same time, the sliding sleeve 3411 applies a traction force to the reinforcing rib 3410 to drive the reinforcing rib 3410 to drive the first supporting rod 349 to swing around the axis of the rotating rod 348.

[0026] When the first supporting rod 349 swings, it synchronously drives the rotating rod 348 to make a reciprocating rotary motion around the axis thereof. The infrared laser 3412 in the middle of the rotating rod 348 moves synchronously with the rotating rod 348 to form a fan-shaped scanning track with the axis of the rotating rod 348 as the center. The infrared laser emitted by the infrared laser 3412 continuously irradiates the surface of the carton to form a continuous laser light belt.

[0027] During the scanning process of the infrared laser 3412, the video recorder 345 continuously captures the laser irradiation area on the surface of the carton, and transmits the image signal containing the laser pattern to the controller 5 in real time. The controller 5 performs gray scale processing, edge detection and other algorithm analysis on the image signal. If the laser light belt in the image is in a continuous straight line, it is judged that the surface of the carton is not damaged and the protective film is intact. If the laser light belt is bent or deformed, it is judged that there are concave or convex defects on the surface of the carton. If the laser light belt is broken or missing, it is judged that the protective film of the coated carton has scratches, peeling or bubbles, etc. The controller 5 generates a carton quality judgment signal according to the analysis result to provide a basis for subsequent sorting.

[0028] During the entire detection process, the scanning assembly 34 realizes the fan-shaped scanning of the infrared laser 3412 through mechanical linkage, and cooperates with the accurate image acquisition of the video recorder 345 to effectively solve the problem of missing detection of subtle defects existing in the traditional fixed-angle detection, and simultaneously realize the synchronous detection of the surface damage of the carton and the damage of the protective film, thereby significantly improving the detection comprehensiveness and accuracy.

[0029] Further, the positioning mechanism 4 includes a mounting plate 41 mounted on the middle of the lower surface of the roller conveyor 2. The front surface of the mounting plate 41 is provided with an alarm lamp 42, and the center position of the lower surface of the mounting plate 41 is provided with a pneumatic cylinder 43. The output end of the pneumatic cylinder 43 is provided with a positioning assembly 44. The pneumatic cylinder 43 drives the positioning assembly 44 to lift, so that the carton is lifted from the roller conveyor 2 to reach the detection point of the detection mechanism 3.

[0030] Further, the positioning assembly 44 comprises a lifting frame 441 installed at the output end of the cylinder 43, four vertical rods 442 are installed at the four corners of the lifting frame 441, a triangular seat 443 is installed at the top of each vertical rod 442, the triangular seat 443 can pass through the roller gap of the roller conveyor 2, the triangular seat 443 supports the four corners of the carton, a trigger rod 444 is inserted into the middle of the triangular seat 443, the trigger rod 444 is triggered by the bottom corner of the carton, and a reset unit 445 is installed at the center of the upper surface of the lifting frame 441.

[0031] Further, the reset unit 445 comprises a disc 4451 installed at the center of the upper surface of the lifting frame 441, a vertical column 4452 is installed at the center of the upper surface of the disc 4451, metal strips 4453 are equidistantly installed along the circumference of the outer wall of the vertical column 4452, and the metal strips 4453 are circumscribed by a power supply and are electrically connected with the alarm lamp 42, a plurality of second supporting rods 4454 are equidistantly installed along the circumference of the outer edge of the upper surface of the disc 4451, a circular ring seat 4455 is installed at the top of each second supporting rod 4454, counterweights 4456 are equidistantly sleeved along the circumference of the outer wall of the circular ring seat 4455, the second supporting rods 4454 support the circular ring seat 4455, the space around the counterweights 4456 is expanded, the counterweights 4456 are prevented from being limited, one end of a connecting rod 4457 is installed at the outer side of each counterweight 4456 through a pin shaft, the other end of the connecting rod 4457 is connected with the bottom of the trigger rod 444 through a pin shaft, the connecting rod 4457 is pushed up by the gravity of the counterweight 4456, the connecting rod 4457 pulls the trigger rod 444 to rise, the trigger rod 444 is reset, the counterweight 4456 is located between two adjacent metal strips 4453, when the counterweight 4456 rotates, the counterweight 4456 can be inserted into the gap of the metal strip 4453, and the metal strip 4453 supplies power for the alarm lamp 42.

[0032] When the cylinder 43 of the positioning mechanism 4 drives the lifting frame 441 to rise, the four triangular seats 443 come into contact with the lower surface of the carton and lift the carton: if the bottom corner of the carton is intact, the bottom corner applies downward pressure to the trigger rod 444 on the triangular seat 443, so that the trigger rod 444 slides downward along the guide hole of the triangular seat 443; when the trigger rod 444 slides downward, the connecting rod 4457 applies tension to the counterweight 4456, so that the counterweight 4456 rotates upward around the outer wall of the circular ring seat 4455; as the counterweight 4456 rotates, the side close to the vertical column 4452 gradually comes into contact with the two adjacent metal strips 4453, since the counterweight 4456 is made of conductive material, the two metal strips 4453 are conductive at this time, so that the circuit of “power supply, metal strip 4453, counterweight 4456, metal strip 4453, alarm lamp 42 and negative electrode of the power supply” is closed, the alarm lamp 42 is electrified and emits light, and a signal that the bottom corner of the carton is intact is fed back to the controller 5.

[0033] When the carton detection is completed, the cylinder 43 drives the lifting frame 441 to descend, and the triangular seat 443 is separated from the bottom of the carton. After that, the downward pressure on the trigger rod 444 disappears, and at this time, the counterweight 4456 rotates downward around the outer wall of the ring seat 4455 under the action of its own gravity. When the counterweight 4456 rotates downward, it exerts an upward thrust on the trigger rod 444 through the connecting rod 4457, prompting the trigger rod 444 to slide upward along the guide hole of the triangular seat 443 and restore to the initial height, ready for the next carton detection. At the same time, the counterweight 4456 is separated from the metal strip 4453, the circuit is disconnected, the alarm lamp 42 is extinguished, and the next detection trigger is waiting.

[0034] If the bottom corner of the carton is damaged (such as missing corner or cracking), the damaged bottom corner cannot exert effective pressure on the corresponding trigger rod 444, and the trigger rod 444 remains stationary. The corresponding counterweight 4456 does not rotate and cannot contact the metal strip 4453 to conduct the circuit. The corresponding alarm lamp 42 remains extinguished. The controller 5 determines that the bottom corner of the carton is damaged according to the extinguished state of the alarm lamp 42 and generates a corresponding sorting signal.

[0035] The reset unit 445 not only realizes the automatic mechanical reset of the trigger rod 444 without the need for an additional power source, but also combines mechanical action with circuit triggering to accurately complete the determination of the damage of the bottom corner of the carton, effectively filling the blind spot of the traditional detection device for the detection of the bottom corner of the carton and ensuring the detection accuracy of the overall structural integrity of the carton.

[0036] Working principle: Step one, the roller conveyor 2 conveys the carton from left to right, making the carton reach the inspection station and the sorting station. At the detection station, the cylinder 43 drives the lifting frame 441 to rise, and the triangular seat 443 lifts the corner of the carton, allowing the carton to gradually rise and reach the detection position. Under the action of its own gravity, the bottom corner of the carton presses the trigger rod 444, prompting the connecting rod 4457 to drive the counterweight 4456 to rotate inward. The counterweight 4456 is inserted between the metal strips 4453, and the counterweight 4456 and the metal strips 4453 form a closed loop. The alarm lamp 42 is powered on and emits light, indicating that the bottom corner of the carton is intact. If the alarm lamp 42 is on, it indicates that the carton has a damaged bottom corner and has not triggered the trigger rod 444. The alarm lamp 42 is on, indicating that the carton has a damaged bottom corner. The bottom corner detection of the carton is realized. Step two, after the carton reaches the detection station, the driver 33 drives the driving gear 343 to rotate the rotating shaft 342, and the swing rod 346 drives the lifting rod 347 to make a circular motion. As the lifting rod 347 slides up and down, the sliding sleeve 3411 slides back and forth on the reinforcing rib 3410, and the first support rod 349 swings back and forth, so that the rotating rod 348 drives the infrared laser 3412 to make a fan-shaped swing. The infrared laser 3412 irradiates the surface of the carton, and the video recorder 345 feeds back the video signal to the controller 5 as an electrical signal. If the laser is in a straight line, it means that the surface of the carton is not damaged. If the laser is curved, it means that the carton has a depression. If the laser is broken, the protective film on the surface of the carton is damaged. The surface of the carton is detected. Step three, the mechanical arm 8 drives the clamp 9 to move between the roller conveyor 2 and the support platform 6, and places the cartons on the two support platforms 6 according to different qualities, and sorts the cartons.

[0037] The above is only the preferred embodiment of the present application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application. These will not affect the effect and practicality of the present application.
