Description

Technical Field

[0001] The present invention relates to the technical field of carton sorting, and in particular to a carton damage detection and sorting device based on visual sensing. Background Art

[0002] Carton damage detection and sorting are of great significance in the fields of logistics and warehousing. They can reduce dependence on manual labor, lower labor costs, and reduce workers' labor intensity. Timely detection and sorting of damaged cartons can prevent damaged goods from continuing to circulate, reduce cargo losses and safety accidents, and ensure that customers receive goods intact, thereby improving customer satisfaction.

[0003] After traditional cartons are loaded with goods, they usually need to be inspected for damage to prevent damage during the packaging process that would affect packaging quality. Currently, the most commonly used efficient inspection method usually uses visual sensing technology, but the cartons usually need to be turned over manually during the inspection process, and cannot be turned over automatically during the inspection process. This is highly dependent on manual labor and is not convenient for automatic sorting based on the inspection results. Summary of the Invention

[0055] Bearing plates 31 are rotatably provided at both ends of the discharging roller 3, and the bearing plates 31 are slidably provided on both sides of the detection channel 2. The bearing plates 31 are driven to rise and fall and slide by external force, and are used to adjust the distance between the discharging roller 3 and the feeding roller 22; specifically, sliding holes 23 are opened on both sides of the detection channel 2 corresponding to the discharging roller 3, and the axial ends of the discharging roller 3 are slidably provided on the inner side of the sliding holes 23, and a connecting frame 33 is fixedly provided on the top of the bearing plate 31, and a second push rod 32 is fixedly provided on the top of the connecting frame 33.

[0057] The transfer assembly 4 includes a bottom plate 41, a side plate 42, a baffle 43 and a movable roller 44. The bottom plate 41 is rotatably set at the bottom of the detection channel 2 and is driven to rotate by the detection channel 2; the side plates 42 are fixedly set on both sides of the bottom plate 41; the baffle 43 is fixedly set on the side of the side plate 42 away from the feed roller 22; the movable roller 44 is arranged between the side plates 42 on both sides, and the movable roller 44 is rotatably connected to the side plates 42.

[0058] The transfer component 4 also includes a limit plate 410, which is slidably arranged on the inner side of the baffle 43 and is located on the top of the movable roller 44. Two limit plates 410 are symmetrically arranged, and the two limit plates 410 are driven by external force to adjust the spacing; specifically, a bidirectional screw rod 47 is rotatably arranged on the outer side of the baffle 43, and a third drive motor 48 for driving the bidirectional screw rod 47 to rotate is fixedly arranged on the outer side of the baffle 43. A screw rod sleeve 49 is arranged on the outer side of the bidirectional screw rod 47, and the screw rod sleeve 49 is fixedly arranged at the end of the limit plate 410, and a sensor 411 is also provided on the side of the baffle 43 close to the carton package 100. The sensor 411 is used to sense and detect the loading status of the carton package 100, so as to realize automatic control of the third drive motor 48 to drive the limit plate 410 to limit the carton package 100.

[0059] A vertical shaft 45 is fixedly provided at the bottom of the base plate 41, and the vertical shaft 45 is rotatably provided at the bottom of the detection channel 2. A driving wheel 46 is coaxially fixedly provided at the bottom of the vertical shaft 45, and an arc-shaped driving plate 5 is meshed on the outer side of the driving wheel 46 to drive the driving wheel 46 to rotate; wherein, a second support plate 14 is fixedly provided on the top of the supporting plate 11, and an arc-shaped driving plate 5 is slidingly provided on the outer side of the second support plate 14, and an auxiliary block 51 is fixedly provided on the outer side of the arc-shaped driving plate 5.

[0060] In the above technical solution, the driving wheel 46 can be a bevel gear, and the corresponding arc-shaped driving plate 5 is an arc-shaped toothed plate. The bevel gear is driven by the arc-shaped toothed plate to drive the bottom plate 41 to rotate through the vertical axis. The auxiliary block 51 mainly serves as a counterweight.

[0061] A gear transmission box 36 is fixedly installed on the outside of the bearing plate 31, and several discharging rollers 3 are linked in the same direction through the gear transmission box 36. A second drive motor 37 is fixedly installed on the outside of the gear transmission box 36, which is used to drive the discharging rollers 3 to rotate synchronously; the second drive motor 37 responds to the first visual inspection instrument 24, the second visual inspection instrument 25 and the third visual inspection instrument 26.

[0062] In another technical solution, a damping surface is provided at the top of the second support plate 14. When the detection channel 2 rotates to turn over the carton package 100, the arc-shaped driving plate 5 moves to the outside of the damping surface.

[0063] The principle and advantages of carton damage detection and sorting device based on visual sensing:

[0064] First, the carton package 100 is placed at the feed port of the detection channel 2 with the help of external force. At this time, the carton package 100 generates pressure on the feed roller 22 at the bottom of the detection channel 2. According to the detection results of the pressure sensor at the axial end of the feed roller 22, the inclination angle required for the carton package 100 to move at the top of the feed roller 22 can be estimated. The smaller the pressure generated by the carton package 100, the larger the required inclination angle is, so as to ensure that the carton package 100 can smoothly enter the interior of the detection channel 2, and prevent the carton package 100 from moving too fast due to a large inclination angle, so that when the carton package 100 approaches the transfer component 4, the first visual inspection instrument 24 at the top of the detection channel 2 can be used to detect damage on the top of the carton package 100.

[0065] When the carton package 100 reaches the transfer position of the transfer component 4, the carton package 100 continues to approach the movable roller 44 at the top of the bottom plate 41 along the inclined direction, and finally leans against the side of the baffle 43 under the guidance of the movable roller 44. At this time, the sensor 411 can detect that the carton package 100 is on the top of the movable roller 44, and then the terminal control system starts to control the third drive motor 48 to drive the bidirectional screw rod 47 to rotate, so that the bidirectional screw rod 47 drives the two outer screw rod sleeves 49 to approach each other to the two sides of the bottom of the carton package 100. At this time, the third visual inspection device 26 located on both sides of the detection channel 2 can perform damage detection on both sides of the carton package 100, and then control the third visual inspection device 26 to detect damage on both sides of the carton package 100. The second push rod 32 drives the bearing plate 31 to move downward, so that the bearing plate 31 drives the slide plate 34 to approach the top of the carton package 100, and finally controls the first drive motor 210 to drive the drive gear 29 to rotate, so that the drive gear 29 drives the first drive motor 210 on the outside of the end plate 21, thereby driving the detection channel 2 to rotate 180° on the inner side of the first support plate 13. During the rotation of the detection channel 2, the bottom plate 41 is driven by the arc-shaped driving plate 5 to rotate, thereby driving the carton package 100 to rotate, so that the other two sides of the carton package 100 rotate toward the third visual inspection device 26 on both sides, thereby realizing the effect of automatic comprehensive inspection of the surrounding side during the flipping process.

[0066] When the bottom plate 41 is driven by the arc-shaped driving plate 5, the driving wheel 46 first engages with the outer side of the arc-shaped driving plate 5, and then when the driving wheel 46 rotates to the end of the arc-shaped driving plate 5, the driving wheel 46 and the arc-shaped driving plate 5 engage with each other. As the detection channel 2 continues to rotate, the driving wheel 46 drives the arc-shaped driving plate 5 to slide relative to the second support plate 14 until the arc-shaped driving plate 5 rotates with the driving wheel 46 to the top of the detection channel 2 (as shown in FIG. Figure 4 As shown), the turning over of the carton package 100 is now completed.

[0067] During the above-mentioned working process, the bottom plate 41 can rotate during the rotation of the detection channel 2. In the actual working process, the rotation of the bottom plate 41 can occur at the initial stage of the rotation of the detection channel 2, or it can occur when the detection channel 2 is about to complete its rotation. As long as the bottom plate 41 can rotate 180° when the detection channel 2 rotates 180°, it will be sufficient. The auxiliary block 51 on one side of the arc-shaped driving plate 5 is provided to enable the driving wheel 46 to first engage with the outer side of the arc-shaped driving plate 5, that is, during the rotation of the detection channel 2, the arc-shaped driving plate first does not slide relative to the second support plate 14, so that the bottom plate 41 can rotate at the initial stage of the rotation of the detection channel 2. This can ensure that the damage detection of the 100-week side of the carton package is completed before the detection channel 2 rotates 180°, and can ensure the effectiveness of the detection of the 100-week side of the carton package.

[0068] Based on the above explanation, the setting of the auxiliary block 51 facilitates the self-rotation of the bottom plate 41 at the initial stage of the rotation of the detection channel 2. Before the detection channel 2 rotates 180°, the bottom plate 41 completes the rotation first. This also helps when the detection channel 2 rotates, the carton package 100 can move directly toward the discharge roller 3 along the side of the bottom plate 41 away from the baffle 43, thereby ensuring the effectiveness of the unloading of the carton package 100.

[0069] When the carton package 100 is turned over and is located on the top of the slide plate 34 and is supported by the ball bearing 35, the second push rod 32 is controlled to drive the bearing plate 31 to reset, so that the bearing plate 31 drives the slide plate 34 and the discharge roller 3 to move downward, thereby making the carton package 100 away from the movable roller 44, and under the action of the tilt angle, the carton package 100 can be automatically moved to the top of the discharge roller 3. At this time, the second visual inspection device 25 located on the opposite side of the discharge roller 3 on one side of the detection channel 2 is used to detect damage on the last side of the carton package 100, thereby achieving a comprehensive inspection of the carton package 100. Finally, the carton package 100 is sorted according to the inspection results of the first visual inspection device 24, the second visual inspection device 25 and the third visual inspection device 26; wherein, the detection principles of the first visual inspection device 24, the second visual inspection device 25 and the third visual inspection device 26 are all existing technologies and will not be repeated here.

[0070] In the above technical solution, if any of the first, second, or third visual inspection devices 24, 25, and 26 detects damage to a packaging box, the second drive motor 37 drives the multiple discharge rollers 3 to rotate in the opposite direction, causing the carton to rest on top of the discharge rollers 3. An external warning device then alerts a worker or robot to remove the damaged carton. Cartons that are not damaged pass directly through the multiple discharge rollers 3 to the next process.

[0071] In another technical solution, the first push rod 12 responds to the first visual inspection device 24, the second visual inspection device 25 and the third visual inspection device 26; when any one of the first visual inspection device 24, the second visual inspection device 25 and the third visual inspection device 26 detects that the packaging box is damaged, the first push rod 12 can drive the supporting plate 11 to rotate relative to the base 1, so that the feed roller 22 and the discharge roller 3 at the top of the supporting plate 11 remain horizontal. At this time, the carton package 100 moved to the top of the discharge roller 3 stays at the top of the discharge roller 3, and an external warning device can also be used to remind the staff or robot to take out the damaged carton.

[0072] In the above technical solution, the warning device responds to the corresponding second drive motor 37 or the first push rod 12 .

[0073] It is worth mentioning that the above detection and sorting method has the following advantages:

[0074] Advantage 1: By driving the detection channel 2 to rotate 180°, the detection channel 2 drives the carton package 100 to turn over, so as to facilitate damage detection on the upper and lower sides of the carton package 100, and during the turning process of the detection channel 2, the transfer component 4 located inside the detection channel 2 rotates, so that the transfer component 4 drives the surrounding sides of the carton package 100 to rotate toward the third visual inspection device 26, thereby achieving the effect of automatically detecting damage on the surrounding sides during the turning process, and adapting to the surrounding side detection of carton packages 100 of different shapes under the support of the transfer component 4; and while turning over, the surrounding sides of the carton package 100 are inspected by the third visual inspection device 26, which reduces the time occupied by the overall process and is conducive to improving the detection efficiency;

[0075] Advantage 2: By providing a rotatable and tiltable carrying plate 11, the inspection channel 2 is tilted. When the carton package 100 is loaded, it relies on its own gravity to move along the top of the feed roller 22 toward the transfer assembly 4. By adjusting the tilt angle of the inspection channel 2, carton packages 100 of different qualities can be loaded at an appropriate speed, thereby ensuring the accuracy of the damage detection of the first visual inspection device 24.

[0076] Advantage three: through the inclined detection channel 2, when the detection channel 2 drives the carton package 100 to turn over, the tilt of the detection channel 2 can automatically move the carton package 100 to the top of the discharge roller 3 for discharge, and move at an appropriate speed, also ensuring the detection accuracy of the second visual inspection device 25;

[0077] Advantage 4: By setting the supporting plate 11 to drive the detection channel 2 to adjust the inclination angle, after the detection, the supporting plate 11 can drive the detection channel 2 to adjust to an elevation angle or a depression angle according to the detection result, so as to facilitate sorting the carton packages 100 on the top of the discharge roller 3 to different positions; wherein, when sorting upward, the discharge roller 3 can be driven to rotate synchronously by the second drive motor 37, and the second drive motor 37 does not need to be started when sorting downward, thereby reducing equipment loss;

[0078] Advantage five: by arranging the ball bearing 35 at the bottom of the slide 34, before turning over, the ball bearing 35 at the bottom of the slide 34 contacts the top of the carton package 100, so that the carton package 100 can be rotated by the transfer component 4 for circumferential side inspection. After turning over, the ball bearing 35 is located at the bottom of the carton package 100. At this time, the ball bearing 35 can ensure that the carton package 100 can be moved to the top of the discharge roller 3 by automatic gravity, thereby ensuring smoothness during the inspection process;

[0079] Advantage six: by setting the arc-shaped driving plate 5 to cooperate with the transfer component 4, when one side of the detection channel 2 rotates, the side away from the baffle 43 also rotates upward, preventing the carton package 100 on the top of the movable roller 44 from sliding downward and losing stability when the baffle 43 rotates upward.

[0080] In actual application, the transfer component 4 drives the carton package 100 to rotate in the following manner:

[0081] First, driven by the detection channel 2, the detection channel 2 drives the bottom driving wheel 46 to roll outside the arc-shaped driving plate 5. At this time, the arc-shaped driving plate 5 relies on the resistance brought by the auxiliary block 51 to maintain stability. When the driving wheel 46 rolls from one end of the arc-shaped driving plate 5 to the other end, it rotates 180°. At this time, the transfer component 4 has driven the carton package 100 to complete the transfer, and the detection channel 2 needs to continue to rotate for flipping. At this time, the detection channel 2 drives the arc-shaped driving plate 5 through the driving wheel 46 to break through the resistance brought by the auxiliary block 51 and slide along the second support plate 14 in an arc. Until the detection channel 2 flips 180°, the driving wheel 46 changes from the bottom of the detection channel 2 to the top. At this time, the arc-shaped driving plate 5 is cooperated with the damping surface. Under the action of the auxiliary block 51's own gravity and the damping surface, the arc-shaped driving plate 5 can be maintained at the top of the second support plate 14.

[0082] When the carton package 100 is sorted, the detection channel 2 starts to rotate in the opposite direction and reset. At this time, under the action of the damping surface, the arc-shaped driving plate 5 still remains at the top of the second support plate 14, so the driving wheel 46 will roll on the outside of the arc-shaped driving plate 5 at this time, realizing the reset of the transfer component 4; when the driving wheel 46 rolls to the end of the tooth segment of the arc-shaped driving plate 5, the driving wheel 46 engages with the arc-shaped driving plate 5, and when the detection channel 2 continues to rotate, the driving wheel 46 drives the arc-shaped driving plate 5 to slide along the second support plate 14 until the detection channel 2 is reset, so as to continue to detect the next carton package 100.

[0083] In the above technical solution, the damping surface is set to increase the friction between the arc-shaped driving plate 5 and the second support plate 14. In the actual working process, the damping surface can be a sponge sheet, a silicone sheet or a rubber sheet. In a specific example of the present application, the damping surface is a rubber sheet arranged at the top of the second support plate 14.

[0084] Its advantage is that the sliding arc-shaped driving plate 5 offsets the unnecessary rotation caused by the excessive rotation radius of the driving wheel 46, preventing the driving wheel 46 from rotating more than 180°, causing the opening side of the transfer component 4 to tilt downward and causing the carton package 100 to lose stability.

[0085] The second advantage is that, under the action of the auxiliary block 51 and the damping surface, no matter the detection channel 2 is rotated to turn over the carton package 100 or the detection channel 2 is reset, the driving wheel 46 first rolls relative to the arc-shaped driving plate 5 to rotate the transfer assembly, and then the driving wheel 46 drives the arc-shaped driving plate 5 to move along the second support plate 14, ensuring that the transfer assembly can rotate in time so that the side away from the baffle 43 can be set toward the feed roller 22 / discharge roller 3, ensuring the effectiveness of feeding and discharging the carton package 100.

[0086] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
