Detailed implementation manner

[0034] The following describes the detailed implementation manner of the present invention in conjunction with the accompanying drawings.

[0035] As Figures 2 to 12 shown, a carton inspection and sorting device for this embodiment includes a loading station 100, an inspection station 300, an unloading station 400, and a moving mechanism 500. The moving mechanism 500 reciprocates between the loading station 100 and the inspection station 300, or between the inspection station 300 and the unloading station 400; the loading station 100 is used to carry multiple products, and detecting multiple products at one time can improve efficiency. In this embodiment, four products are detected at one time; the moving mechanism 500 simultaneously sends the four products on the loading station 100 to the inspection station 300, and the inspection station 300 detects whether the products are qualified. The qualified products are sent by the moving mechanism 500 to the unloading station 400 for unloading; in order to collect unqualified products, a recycling station 600 is also provided between the inspection station 300 and the unloading station 400. The unqualified products are sent by the moving mechanism 500 to the recycling station 600 for recycling; thus, a detection process is completed.

[0036] In order to improve the working efficiency of the moving mechanism 500, the loading station 100, the inspection station 300, the recycling station 600, and the unloading station 400 are arranged in sequence in a straight line direction. The moving mechanism 500 includes a first moving mechanism 510 and a second moving mechanism 520. The first moving mechanism 510 reciprocates between the loading station 100 and the inspection station 300, and the second moving mechanism 520 reciprocates between the inspection station 300 and the unloading station 400. The first moving mechanism 510 and the second moving mechanism 520 are distributed on both sides of the inspection station 300. The two moving mechanisms cooperate with each other and do not interfere with each other, greatly improving the working efficiency.

[0037] Specifically, the detection station 300 includes a detection fixture 310 and a CCD detection device 320. There are the same number of toolings 200 on the detection fixture 310 as that of the feeding station 100, that is, four toolings 200. The CCD detection device 320 is located above the detection fixture 310. The detection fixture 310 includes a bottom plate 311, a rotating bracket 312 and a motor 313. The tooling 200 is installed on the rotating bracket 312, and the motor 313 can drive the rotating bracket 312 to rotate on the bottom plate 311. Four CCD detection devices 320 are evenly distributed around the rotation axis of the rotating bracket 312. The CCD detection device 320 is arranged obliquely above the rotating bracket 312, and the inclination angles of the four CCD detection devices 320 are the same. The moving mechanism 500 simultaneously sends the four products on the feeding station 100 to the four toolings 200 of the detection station 300. The motor 313 is started to drive the rotating bracket 312 to rotate, and the four cartons are visually detected by the CCD detection device 320 above. Since the CCD detection device 320 is arranged obliquely above the rotating bracket 312 and four are evenly distributed around the rotation axis of the rotating bracket 312, the rotating bracket 312 only needs to rotate 90° to complete the detection, without rotating 360°, greatly improving the detection efficiency. Among them, the CCD detection device 320 has a certain viewing angle. Therefore, the distance between the four toolings 200 on the detection fixture 310 is reduced to avoid moving out of the viewing range during the rotation process, and being as compact as possible can ensure normal detection;

[0038] Specifically, the loading station 100 includes an integration fixture 110. There are four toolings 200 for supporting products on the integration fixture 110. The integration fixture 110 includes a base 111, a fixed bracket 112, three movable brackets 113 and a variable pitch cylinder 114. Toolings 200 are provided on both the fixed bracket 112 and the movable brackets 113. A guide rail 115 is provided on the base 111. The fixed bracket 112 is located at one end of the guide rail 115. The movable brackets 113 all slide on the guide rail 115. The variable pitch cylinder 114 can drive the three movable brackets 113 to move towards the fixed bracket 112 until the distances between the toolings 200 are the same and are the same as the distances between the four toolings 200 on the detection fixture 310. The purpose is to facilitate the grasping of the first moving mechanism 510. The distances between the four toolings 200 on the detection fixture 310 are fixed and relatively small. A grasping device matching the distances needs to be designed on the first moving mechanism 510. The distances between the four toolings 200 on the integration fixture 110 should be consistent to facilitate grasping. However, in order to improve the degree of automation, in this embodiment, the manipulator is used to load the toolings 200 on the integration fixture 110. If the distances between the toolings 200 are too small, it is not conducive to the loading operation of the manipulator. At this time, the variable pitch cylinder 114 can drive the three movable brackets 113 to move away from the fixed bracket 112 until the distances between the toolings 200 meet the requirements of the manipulator operation. At this time, it is used for the manipulator to load. After the loading is completed, the three movable brackets 113 move towards the fixed bracket 112 until the grasping distance, and at this time, it is used for the first moving mechanism 510 to grasp;

[0039] Specifically, refer to Figure 7 , three push rods 116 corresponding to the three movable brackets 113 are connected to the piston rod of the variable pitch cylinder 114. The distances between the three push rods 116 are constant and the same as the operation distances of the manipulator. The movable bracket 113 farthest from the fixed bracket 112 is fixedly connected to the push rod 116, and the other movable brackets 113 are movably connected to the push rod 116; when the variable pitch cylinder 114 drives the push rod 116 to move towards the fixed bracket 112, the movable bracket 113 farthest away moves synchronously, and the push rod 116 is separated from the other movable brackets 113. The movable bracket 113 farthest away pushes the other movable brackets 113 to move until the grasping distance; when the variable pitch cylinder 114 drives the push rod 116 to move away from the fixed bracket 112, the movable bracket 113 farthest away moves synchronously. The other movable brackets 113 will be pushed to move only after the push rod 116 contacts the other movable brackets 113. After the push rod 116 is in place, the distances between the three movable brackets 113 are the same as the distances between the three push rods 116, meeting the requirements of the manipulator operation;

[0040] Among them, the tooling 200 is in a plate shape, and through holes 210 for placing the paper box are provided on the tooling 200. Since the square grooves and rectangular grooves on the paper box are both protruding, the through holes 210 can accommodate both of them at the same time. The edge of the paper box is supported around the through holes 210. At this time, it is more convenient to place or grab the paper box from above the through holes 210.

[0041] In order to match the work 200, the first moving mechanism 510 includes a driving mechanism 511, a linear slide rail 512, a slider 513, a lifting cylinder 514 and a suction tooling 515. The linear slide rail 512 extends along the direction from the feeding station 100 to the inspection station 300. The driving mechanism 511 drives the slider 513 to reciprocate along the linear slide rail 512. The lifting cylinder 514 is installed on the slider 513. The lifting cylinder 514 drives the suction tooling 515 to move up and down on the slider 513. The suction tooling 515 is located above the integration jig 110 and the inspection jig 310. Suction cups 516 corresponding to the number of toolings 200 on the inspection jig 310 are provided on the suction tooling 515. In order to facilitate suction, multiple suction cups 516 correspond to the same product. The suction cups 516 corresponding to the same product are in a group. The distance between each group of suction cups 516 is the same as the distance between the four toolings 200 on the inspection jig 310.

[0042] For the sake of unity, the second moving mechanism 520 has the same structure as the first moving mechanism 510. The linear slide rail on the second moving mechanism 520 extends along the direction from the inspection station 300 to the discharging station 400. The suction tooling on the second moving mechanism 520 is located above the inspection jig 310, the recycling station 600 and the flipping jig 410. Among them, the recycling station 600 includes a recycling box 610. The top of the recycling box 610 is open. The qualified products are grabbed by the second moving mechanism 520 and sent to the flipping jig 410 along the linear slide rail. When the unqualified products are grabbed by the second moving mechanism 520 and moved along the linear slide rail to above the recycling box 610, they can be directly thrown into the recycling box 610.

[0043] The discharging station 400 includes a flipping jig 410 and a conveyor belt 420. There are no less than the number of toolings 200 on the inspection jig 310 provided on the flipping jig 410. The conveyor belt 420 is located below the flipping jig 410. The flipping jig 410 can be horizontally flipped to make the product fall into the conveyor belt 420. The qualified products are grabbed by the second moving mechanism 520 and sent to the tooling 200 on the flipping jig 410. Then, the flipping jig 410 is flipped 180°. The paper box is separated from the through hole 210 of the tooling 200 and falls onto the conveyor belt 420 under the action of gravity, and is conveyed by the conveyor belt 420 to complete the discharging.

[0044] Among them, the flipping fixture 410 includes a flipping bracket 411, a flipping motor 412, a flipping shaft 413, and a clamping mechanism 414. The flipping shaft 413 is arranged in a horizontal direction. The flipping bracket 411 is fixed on the flipping shaft 413. The tooling 200 is installed side by side along the width direction on the flipping bracket 411. The flipping motor 412 drives the flipping shaft 413 to rotate, which can drive the flipping bracket 411 and the tooling 200 thereon to flip 180°. The clamping mechanism 414 includes a cylinder 415 and a C-shaped clamping plate 416. The cylinder 415 and the C-shaped clamping plate 416 are symmetrically arranged on both sides of the tooling 200 in the length direction. A plurality of toolings 200 are all located inside the C-shaped clamping plates 416 on both sides. The cylinder 415 drives the C-shaped clamping plates 416 on both sides to move towards each other, so that the C-shaped clamping plates 416 block the paper boxes on the tooling 200. At this time, when the flipping bracket 411 flips 180°, the paper boxes are blocked by the C-shaped clamping plates 416 and will not fall off by themselves. After the flipping is completed, the cylinder 415 drives the C-shaped clamping plates 416 on both sides to move in the opposite direction at the same time, and the paper boxes are unobstructed. At this time, they can fall off the through holes 210 of the tooling 200 under their own weight and fall onto the conveyor belt 420.

[0045] The working principle of the present invention:

[0046] The variable pitch cylinder 114 operates to move the three moving brackets 113 away from the fixed bracket 112. The manipulator is used to feed the tooling 200 of the integration jig 110, and place the paper boxes from above into the through holes 210 of the four toolings 200. The variable pitch cylinder 114 operates again, and the three moving brackets 113 move towards the fixed bracket 112 until the grasping pitch. The suction tooling 515 of the first moving mechanism 510 moves along the linear slide rail 512 through the slider 513 to the upper part of the tooling 200 of the integration jig 110. The suction tooling 515 descends under the action of the lifting cylinder 514, and simultaneously grabs the paper boxes on the four toolings 200 through the suction cups 516, rises to drive the paper boxes away from the tooling 200, and moves along the linear slide rail 512 to the upper part of the inspection jig 310, and descends to place the paper boxes on the four toolings 200 of the inspection jig 310 at the same time. The motor 313 starts to drive the rotating bracket 312 to rotate 90°, and the four CCD detection devices 320 above are used to perform visual inspection on the four paper boxes. The inspection results are fed back to the controller. After the inspection is completed, the paper boxes are grabbed by the second moving mechanism 520 and move along the linear slide rail. When the unqualified products move above the recycling box 610, they are directly thrown into the recycling box 610. The qualified products are transported to the tooling 200 of the flipping jig 410. At this time, the cylinder 415 drives the C-shaped clamping plates 416 on both sides to move towards each other, and the C-shaped clamping plates 416 block the paper boxes on the tooling 200. The flipping motor 412 drives the flipping shaft 413 to rotate, driving the flipping bracket 411 and the tooling 200 thereon to flip 180°. The paper boxes are blocked by the C-shaped clamping plates 416 and will not fall off by themselves. After the flipping is completed, the cylinder 415 drives the C-shaped clamping plates 416 on both sides to move in the opposite direction at the same time. The paper boxes are unobstructed, and at this time they can fall off the through holes 210 of the tooling 200 under their own weight and fall onto the conveyor belt 420, and are conveyed by the conveyor belt 420 to complete the unloading.
