Both ends of the first push rod 12 are rotatably connected to the base 1 and the bearing plate 11 respectively; the detection channel 2 is rotatably arranged on the top of the bearing plate 11 and can reciprocally rotate 180° axially under the drive of an external force for turning over the carton packages 100 inside. Feeding rollers 22 are arranged in a row on the bottom side inside the detection channel 2 for guiding the feeding of the carton packages 100; the discharge rollers 3 are arranged in a row inside the detection channel 2 for guiding the automatic discharge of the carton packages 100; the transfer component 4 is rotatably arranged inside the detection channel 2 for receiving the carton packages 100 guided by the feeding rollers 22. The transfer component 4 can reciprocally rotate 180° in the radial direction of the detection channel 2 under the drive of the detection channel 2; wherein, a first vision detector 24 is fixedly arranged at the top of the detection channel 2 corresponding to the feeding rollers 22, a second vision detector 25 is fixedly arranged at the bottom of the detection channel 2 corresponding to the discharge rollers 3, and third vision detectors 26 are fixedly arranged on both sides of the detection channel 2 corresponding to the transfer component 4. The three vision detectors are used for detecting damage on six sides of the carton package 100; pressure sensors are arranged at the bottoms of the shaft ends of the feeding rollers 22 for automatically adjusting the inclination angle of the detection channel 2 by detecting the pressure generated by the carton packages 100.

[0023] First support plates 13 are fixedly arranged on both sides of the top of the bearing plate 11. The detection channel 2 is rotatably arranged inside the first support plates 13. End plates 21 are fixedly arranged at both ends of the detection channel 2, and the end plates 21 are rotatably arranged inside the first support plates 13; wherein, the detection channel 2 is inclined under the drive of the bearing plate 11 for guiding the carton packages 100 to reach the position of the transfer component 4 through the feeding rollers 22 and for discharging the carton packages 100 along the top of the discharge rollers 3; a toothed ring 28 is fixedly arranged on the outside of one of the end plates 21, a driving gear 29 is meshed on the outside of the toothed ring 28, the driving gear 29 is fixedly arranged at the driving end of a first driving motor 210, and the first driving motor 210 is fixedly connected to the bearing plate 11 for driving the detection channel 2 to reciprocally rotate.

[0024] Bearing plates 31 are rotatably arranged at both ends of the discharge rollers 3. The bearing plates 31 are slidably arranged on both sides of the detection channel 2. The bearing plates 31 are driven by an external force to lift and slide for adjusting the distance between the discharge rollers 3 and the feeding rollers 22; specifically, sliding holes 23 are opened on both sides of the detection channel 2 corresponding to the discharge rollers 3. The shaft ends of the discharge rollers 3 are slidably arranged inside the sliding holes 23. A connecting frame 33 is fixedly arranged at the top of the bearing plate 31, a second push rod 32 is fixedly arranged at the top of the connecting frame 33, and the second push rod 32 is fixedly arranged at the top of the detection channel 2 through a fixing plate 27 for driving the connecting frame 33 to lift and move.

[0025] A slide plate 34 is fixedly arranged between the bearing plates 31 on both sides. Ball beads 35 are arranged in an array at the bottom of the slide plate 34 and are used to press the top of the carton package 100. Among them, the ball beads 35 are located at the top of the transfer assembly 4. When the transfer assembly 4 rotates, it drives the carton package 100 to rotate at the bottom of the ball beads 35.

[0026] The transfer assembly 4 includes a bottom plate 41, side plates 42, a baffle 43 and movable rollers 44. The bottom plate 41 is rotatably arranged at the bottom of the detection channel 2 and rotates under the drive of the detection channel 2. The side plates 42 are fixedly arranged on both sides of the bottom plate 41. The baffle 43 is fixedly arranged on the side of the side plate 42 away from the feeding roller 22. The movable rollers 44 are arranged between the side plates 42 on both sides, and the movable rollers 44 are rotatably connected to the side plates 42.

[0027] The transfer assembly 4 further includes a limiting plate 410. The limiting plate 410 is slidably arranged inside the baffle 43 and is located at the top of the movable rollers 44. There are two limiting plates 410 arranged symmetrically, and the distance between the two limiting plates 410 is adjusted by an external force. Specifically, a bidirectional lead screw 47 is rotatably arranged outside the baffle 43, and a third drive motor 48 for driving the bidirectional lead screw 47 to rotate is fixedly arranged outside the baffle 43. A lead screw sleeve 49 is arranged outside the bidirectional lead screw 47. The lead screw sleeve 49 is fixedly arranged at the end of the limiting plate 410. Moreover, a sensor 411 is arranged on the side of the baffle 43 close to the carton package 100. The sensor 411 is used to sense the feeding condition of the carton package 100, so as to automatically control the operation of the third drive motor 48 to drive the limiting plate 410 to limit the carton package 100.

[0028] A vertical shaft 45 is fixedly arranged at the bottom of the bottom plate 41. The vertical shaft 45 is rotatably arranged at the bottom of the detection channel 2. A driving wheel 46 is coaxially fixedly arranged at the bottom of the vertical shaft 45. An arc driving plate 5 is meshed outside the driving wheel 46 and is used to drive the driving wheel 46 to rotate. Among them, a second support plate 14 is fixedly arranged on the top of the bearing plate 11. The arc driving plate 5 is slidably arranged outside the second support plate 14, and an auxiliary block 51 is fixedly arranged outside the arc driving plate 5.

[0029] In the above technical solution, the driving wheel 46 can be a bevel gear. Correspondingly, the arc 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 shaft. The main function of the auxiliary block 51 is for counterweight.

[0030] A gear transmission box 36 is fixedly arranged outside the bearing plate 31. A plurality of discharging rollers 3 are linked in the same direction through the gear transmission box 36. A second drive motor 37 is fixedly arranged outside the gear transmission box 36 and is used to drive the discharging rollers 3 to rotate synchronously. The second drive motor 37 responds to the first vision detector 24, the second vision detector 25 and the third vision detector 26.

[0031] 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 driving plate 5 moves to the outside of the damping surface.

[0032] Principle and advantages of the carton damage detection and sorting device based on visual sensing: First, the carton package 100 is placed at the feeding port of the detection channel 2 by means of external force. At this time, the carton package 100 generates pressure on the feeding roller 22 at the bottom of the detection channel 2. According to the detection result of the pressure sensor at the shaft end of the feeding roller 22, the inclination angle required for the carton package 100 to move on the top of the feeding roller 22 can be estimated. The smaller the pressure generated by the carton package 100, the larger the required inclination angle, 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. When the carton package 100 approaches the transfer component 4, the first vision detector 24 at the top of the detection channel 2 can detect the damage of the top of the carton package 100.

[0033] When the carton package 100 reaches the transfer position of the transfer component 4, the carton package 100 continues to move along the inclined direction towards the movable roller 44 on the top of the bottom plate 41, and finally leans against one side of the baffle 43 under the guidance of the movable roller 44. At this time, the inductor 411 can detect that the carton package 100 is located on the top of the movable roller 44. Then the terminal control system starts to control the third driving motor 48 to operate and drive the bidirectional lead screw 47 to rotate, so that the bidirectional lead screw 47 drives the two lead screw sleeves 49 on the outside to approach each other to both sides of the bottom of the carton package 100. At this time, the third vision detectors 26 on both sides of the detection channel 2 can detect the damage of both sides of the carton package 100. Then, control the second push rod 32 to drive 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. Finally, control the first driving motor 210 to drive the driving gear 29 to rotate, so that the driving gear 29 drives the first driving motor 210 outside the end plate 21, thereby driving the detection channel 2 to rotate 180° inside the first support plate 13. During the rotation of the detection channel 2, the bottom plate 41 rotates under the drive of the arc driving plate 5, thereby driving the carton package 100 to rotate, so that the other two sides of the carton package 100 rotate towards the third vision detectors 26 on both sides, achieving the effect of automatically and comprehensively detecting the circumference during the turnover process.

[0034] During the process of the bottom plate 41 being driven by the arc driving plate 5, the driving wheel 46 first engages on the outer side of the arc driving plate 5. Subsequently, when the driving wheel 46 rotates to the end of the arc driving plate 5, the driving wheel 46 and the arc driving plate 5 are engaged with each other. As the detection channel 2 continues to rotate, the driving wheel 46 drives the arc driving plate 5 to slide relative to the second support plate 14 until the arc driving plate 5 rotates to the top of the detection channel 2 with the driving wheel 46 (as Figure 4 shown), at this time, the turning over of the carton package 100 is completed.

[0035] During the above working process, the bottom plate 41 can rotate itself 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 at the end when the detection channel 2 is about to complete the rotation. As long as the bottom plate 41 can rotate 180° when the detection channel 2 rotates 180°; the setting of the auxiliary block 51 on one side of the arc driving plate 5 is to enable the driving wheel 46 to first engage on the outer side of the arc driving plate 5, that is, during the rotation of the detection channel 2, the arc driving plate does not slide relative to the second support plate 14 first, so that the bottom plate 41 can rotate itself at the initial stage of the rotation of the detection channel 2, which can ensure that the damage detection of the circumferential side of the carton package 100 is completed before the detection channel 2 rotates 180°, and can ensure the effectiveness of the circumferential side detection of the carton package 100.

[0036] Based on the foregoing explanation, the setting of the auxiliary block 51 facilitates the 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 first completes the rotation, which also helps the carton package 100 to move directly towards the discharge roller 3 along the side of the bottom plate 41 away from the baffle 43 when the detection channel 2 rotates, ensuring the effectiveness of the discharging of the carton package 100.

[0037] When the carton package 100 is turned over and located on the top of the slide plate 34 and supported by the balls 35, at this time, control the second push rod 32 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 moving the carton package 100 away from the movable roller 44. And under the action of the inclination angle, the carton package 100 can be automatically moved to the top of the discharge roller 3. At this time, the second vision detector 25 on the side of the detection channel 2 opposite to the discharge roller 3 detects the last side of the carton package 100 for damage, achieving the effect of comprehensive detection of the carton package 100. Finally, the carton package 100 is sorted according to the detection results of the first vision detector 24, the second vision detector 25 and the third vision detector 26; among them, the detection principles of the first vision detector 24, the second vision detector 25 and the third vision detector 26 are all prior arts and will not be elaborated here.

[0038] In the above technical solution, when any one of the first vision detector 24, the second vision detector 25, and the third vision detector 26 detects that the packing box is damaged, the second drive motor 37 drives the plurality of discharge rollers 3 to rotate in the reverse direction, so that the cardboard box stays at the top of the discharge rollers 3, and an external warning device is used to remind the staff or the manipulator to take out the damaged cardboard box. The cardboard boxes without damage directly enter the next process through the plurality of discharge rollers 3.

[0039] In another technical solution, the first push rod 12 responds to the first vision detector 24, the second vision detector 25, and the third vision detector 26; when any one of the first vision detector 24, the second vision detector 25, and the third vision detector 26 detects that the packing box is damaged, the first push rod 12 can drive the bearing plate 11 to rotate relative to the base 1, so that the feeding roller 22 and the discharge roller 3 at the top of the bearing plate 11 are kept horizontal. At this time, the cardboard box package 100 moved to the top of the discharge roller 3 stays at the top of the discharge roller 3. Similarly, an external warning device can be used to remind the staff or the manipulator to take out the damaged cardboard box.

[0040] In the above technical solution, the warning device responds to the corresponding second drive motor 37 or the first push rod 12.

[0041] It should be noted that the above detection and sorting method has the following advantages: Advantage 1: By driving the detection channel 2 to rotate 180°, the detection channel 2 drives the cardboard box package 100 to turn over, so as to facilitate the damage detection of the upper and lower sides of the cardboard box package 100. And during the turnover process of the detection channel 2, the transfer assembly 4 inside the detection channel 2 rotates automatically, so that the transfer assembly 4 drives the four sides of the cardboard box package 100 to rotate laterally towards the third vision detector 26, achieving the effect of automatically detecting the damage of the peripheral side during the turnover process, and adapting to cardboard box packages 100 of different shapes for peripheral side detection under the support of the transfer assembly 4; and while turning over, the peripheral side of the cardboard box package 100 is detected by the third vision detector 26, reducing the overall process time occupied, which is beneficial to improving the detection efficiency; Advantage 2: By setting the rotatable and inclined bearing plate 11 to drive the detection channel 2 to incline, so that when the cardboard box package 100 is loaded, relying on the gravity of the cardboard box package 100 itself, it approaches the transfer assembly 4 along the top of the feeding roller 22, and by adjusting the inclination angle of the detection channel 2, cardboard box packages 100 of different masses can be loaded at an appropriate speed to ensure the accuracy of the damage detection by the first vision detector 24; Advantage 3: Through the detection channel 2 set obliquely, after the detection channel 2 drives the carton package 100 to turn over, under the action of the inclination of the detection channel 2, the carton package 100 can be automatically moved to the top of the discharge roller 3 for discharging, and move at an appropriate speed, which also ensures the detection accuracy of the second vision detector 25; Advantage 4: By setting the bearing plate 11 to drive the detection channel 2 to adjust the inclination angle, after detection, according to the detection result, the bearing plate 11 can drive the detection channel 2 to adjust to the elevation angle or depression angle state, so as to sort the carton packages 100 at the top of the discharge roller 3 to different positions; among them, when sorting upward, the discharge roller 3 can be driven to rotate synchronously by the second drive motor 37, and when sorting downward, the second drive motor 37 does not need to be started, reducing equipment wear and tear; Advantage 5: By setting the balls 35 at the bottom of the slide plate 34, before turning over, the balls 35 at the bottom of the slide plate 34 contact the top of the carton package 100, so that the carton package 100 can rotate under the drive of the transfer assembly 4 for circumferential detection. When turning over, the balls 35 are located at the bottom of the carton package 100. At this time, the balls 35 can ensure that the carton package 100 can move to the top of the discharge roller 3 by its own gravity to ensure the smoothness of the detection process; Advantage 6: By setting the arc driving plate 5 to cooperate with the transfer assembly 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.

[0042] In practical applications, the rotation mode of the transfer assembly 4 driving the carton package 100: First, driven by the detection channel 2, the driving wheel 46 at the bottom of the detection channel 2 rolls on the outside of the arc driving plate 5. At this time, the arc driving plate 5 remains stable by relying on the resistance brought by the auxiliary block 51. When the driving wheel 46 rolls from one end of the arc driving plate 5 to the other end, it rotates 180°. At this time, the transfer assembly 4 has driven the carton package 100 to complete the transfer, and the detection channel 2 needs to continue to rotate for turning over. At this time, the detection channel 2 drives the arc driving plate 5 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 is turned over by 180°. At this time, the driving wheel 46 changes from the bottom of the detection channel 2 to the top. At this time, the arc driving plate 5 is fitted at the damping surface. Under the action of the self-gravity of the auxiliary block 51 and the damping surface, the arc driving plate 5 can be kept at the top of the second support plate 14.

[0043] After the carton package 100 is sorted, the detection channel 2 starts to rotate reversely to reset. At this time, under the action of the damping surface, the arc driving plate 5 still remains at the top of the second support plate 14. Therefore, the driving wheel 46 will roll outside the arc driving plate 5 at this time, realizing the reset of the transfer assembly 4. When the driving wheel 46 rolls to the end of the tooth section of the arc driving plate 5, the driving wheel 46 engages with the arc driving plate 5. Under the condition that the detection channel 2 continues to rotate, the driving wheel 46 drives the arc driving plate 5 to slide along the second support plate 14 until the detection channel 2 is reset, facilitating the continuous detection of the next carton package 100.

[0044] In the above technical solution, the damping surface is set to increase the friction between the arc driving plate 5 and the second support plate 14. During 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 provided at the top of the second support plate 14.

[0045] Advantage 1: The arc driving plate 5 provided by sliding offsets the excessive rotation caused by the too large rotation radius of the driving wheel 46, preventing the opening side of the transfer assembly 4 from tilting downward after the rotation angle of the driving wheel 46 exceeds 180°, resulting in the loss of stability of the carton package 100.

[0046] Advantage 2: Under the action of the auxiliary block 51 and the damping surface, whether the detection channel 2 rotates to turn over the carton package 100 or the detection channel 2 is reset, the driving wheel 46 first rolls relative to the arc driving plate 5 to make the transfer assembly rotate, and then the driving wheel 46 drives the arc 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 face the feeding roller 22 / the discharging roller 3, ensuring the effectiveness of the feeding and discharging of the carton package 100.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
