[0038] The main function of the conveying mechanism 1 32 is to realize the initial side positioning of the packaging box after it is placed arbitrarily and to automatically flip the horizontal placement to the vertical placement, so that the packaging box is placed vertically when it moves on the upper end of the conveying track 1 2;

[0039] The sorting mechanism 31 can detect whether the packaging box is placed with the front side facing up or the back side facing up, and guide it to the second conveying track 17 if it is placed with the front side facing up, and guide it to the third conveying track 18 if it is placed with the back side facing up;

[0040] The conveying track 3 18 is used to perform a 180-degree flipping process on the packaging box placed with the reverse side facing upwards, and after flipping, the packaging box is driven away from the clamping arm 20 for flipping by the output mechanism 28 .

[0042] Specifically, the main function of the baffle 6 is to utilize the effect of position interference to drive one side of the packaging box to stop, and then the other side continues to move to achieve the effect of flipping 90 degrees.

[0043] In a specific embodiment of the present invention, the sorting mechanism 31 includes a connecting frame 9 and a rotating frame 8. The connecting frame 9 is fixedly installed on the upper end of one side of the mounting frame 1, and a sensor 15 is fixed on the lower end of the connecting frame 9.

[0044] Specifically, sensor 15 is connected to the back-end control system and can sense whether the packaging box is facing up or back-end facing up. The sensor 15 is mainly connected to the back-end control system by a WeChat camera, and can perform dynamic shooting, display the shot image on the top of the display, and then judge whether it needs to be turned over based on whether printed text appears in the image display.

[0045] In a specific embodiment of the present invention, a rotating frame 8 is rotatably installed on one side of a mounting frame 1, a bracket 7 is fixed at the lower end of the mounting frame 1, a rotating plate 2 14 is rotatably installed between the brackets 7, a rotating plate 11 is rotatably installed at the lower end of the rotating frame 8, a hydraulic cylinder 13 is fixed on the surface of the rotating plate 2 14, a hydraulic rod 12 is inserted into the inside of the hydraulic cylinder 13, and the hydraulic rod 12 is fixedly connected to one side of the rotating plate 11.

[0046] Specifically, the hydraulic cylinder 13 can drive the hydraulic rod 12 to drive the rotating frame 8 to rotate a certain angle to achieve the diversion effect of the packaging box. The design of the rotating plate 11 and the rotating plate 2 14 is mainly to provide the hydraulic rod 12 with a feasible rotation and extension movement to prevent the problem of interference from the east.

[0047] When the hydraulic rod 12 is at the bottom, one end of the rotating frame 8 just fits against one side of the conveying track 1 2 at the lower end of the conveying mechanism 2 30;

[0048] When the hydraulic rod 12 is at the top, the rotating frame 8 is in a parallel state, and one end just fits against one side of the second conveying track 17 at the upper end of the second conveying mechanism 30 .

[0049] In a specific embodiment of the present invention, the conveying mechanism 2 30 includes a mounting frame 2 16, which is divided into two layers. The upper layer is a conveying track 2 17 distributed in a linear array, and the lower layer is a conveying track 3 18 with a concave design. The flipping mechanism 29 is located in the middle of the conveying track 3 18.

[0050] In a specific embodiment of the present invention, clamping arms 20 are provided on both sides of the flipping mechanism 29, the upper surface of the lower clamping arm 20 is flush with the upper end of the conveying track three 18, and a servo motor 19 is fixed to the outer wall of one side of the mounting frame two 16, and the output shaft of the servo motor 19 is fixedly connected to the rotation center of one side of the clamping arm 20.

[0051] Specifically, the servo motor 19 can drive the clamping arm 20 inside the flipping mechanism 29 to rotate 180 degrees to achieve a flipping effect of the packaging box.

[0052] In a specific embodiment of the present invention, a fixing frame 21 is fixed to the lower end of the second mounting frame 16 , and a guide mechanism 28 is provided at the upper end of the fixing frame 21 .

[0053] Specifically, the fixed frame 21 is used to install the guide mechanism 28 to prevent the position interference problem when the clamping arm 20 inside the flipping mechanism 29 rotates.

[0054] In a specific embodiment of the present invention, the export mechanism 28 includes a guide wheel 26, which is rotatably installed between the moving blocks 27. The lower end of the moving block 27 is plugged into the interior of the fixed frame 21. A spring 25 is fixed between the lower end of the moving block 27 and the upper end of the fixed frame 21. A rotating motor 24 is fixed to the outer wall of one side of the moving block 27, and the output shaft of the rotating motor 24 is fixedly connected to the rotation center of one side of the guide wheel 26.

[0055] Specifically, the upper surface of the guide wheel 26 is higher than the upper surface of the lower gripper of the clamping arm 20. The design of the spring 25 can ensure that the guide wheel 26 is in stable contact with the lower surface of the packaging box and slightly squeezes it, and then when the guide wheel 26 rotates, it can ensure that the packaging box is moved out.

[0056] In a specific embodiment of the present invention, a mounting plate 23 is fixed in the middle of one side of the mounting frame 16, and sensors 22 distributed in a linear array are fixed at the lower end of the mounting plate 23. The sensors 22 can sense whether there is a packaging box passing by the lower end, and cooperate to realize the transportation of packaging boxes on the upper and lower sides without the problem of convergence and collision.

[0057] In a specific embodiment of the present invention, the rollers inside the conveying mechanism 1 32 and the conveying mechanism 2 30 are linearly distributed and spaced one centimeter apart from each other, and the rollers are driven by built-in independent driving devices;

[0058] The rotating frame 8 is also provided with a plurality of rollers distributed in a linear array, and each roller has a built-in driving device for driving the rotation. These independently moving rollers are common device structures of conveying production lines and will not be described in detail here.

[0059] A method for using a packaging printing box conveying device comprises the following steps:

[0060] S1: Place the packaging box at one end of the conveying track 2 on one side of the conveying mechanism 32. The packaging box can be placed irregularly. After placement, the camera on the side of the limit plate 4 will detect the placement of the object, and then the linear motor 5 will drive the limit plate 4 to move toward the side of the limit block 3. The limit plate 4 pushes one side of the packaging box to fit with the side of the limit block 3. If the packaging box is placed horizontally, the side of the packaging box facing the limit plate 4 will collide with the baffle 6 during movement, and then the other side of the packaging box continues to move. The packaging box can achieve the effect of converting from horizontal to vertical transportation. If the packaging box is placed vertically at the beginning, it will not collide with the baffle 6. One of the functions of the conveying mechanism 32 is to achieve the automatic positioning and reversal of the packaging box by 90 degrees, so that it can be finally transported vertically.

[0061] S2: When the packaging box moves through the lower end of the connecting frame 9, the sensor 15 detects the passing of the packaging box, and then can detect whether the surface of the packaging box is facing up or the back. If it is facing up, the hydraulic cylinder 13 on one side will drive the hydraulic rod 12 to the maximum stroke, and the rotating frame 8 will dock with the conveying track 2 17 horizontally, and the packaging box will move along the path of the conveying track 2 17. When the back is facing up, the hydraulic rod 12 falls back to the lowest point, and one end of the rotating frame 8 docks with the conveying track 3 18. The packaging box moves along the path of the conveying track 1 2, and then moves to the middle to participate in a 180-degree flip;

[0062] S3: When the package with the reverse side facing upward moves to the flip mechanism 29, it will be directly inserted between the clamping arms 20, and then the servo motor 19 will start to rotate 180 degrees, and the package will flip 180 degrees and squeeze the guide wheel 26. The guide wheel 26 will slide out from the middle of the clamping arm 20 under the drive of the rotating motor 24 and enter the conveying track 3 18 to continue moving;

[0063] S4: In order to prevent the movement interference of the packaging boxes between the conveyor track three 18 and the conveyor track two 17 after they are gathered, when the conveyor track three 18 moves to one side to participate in mixing, the sensor two 22 will detect whether there is a packaging box passing by the lower end. If so, the conveyor track two 17 will stop at the corner to stop the packaging box that is about to collide. After the packaging box at the lower end moves out, the packaging box at the upper end moves again.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and improved concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.

After placement, the camera on one side of the limit plate will detect the placement of the object, and then use the linear motor to drive the limit plate to move toward the side of the limit block. The limit plate pushes one side of the packaging box to fit with the side of the limit block. If the packaging box is placed horizontally, the side of the packaging box facing the limit plate will collide with the baffle plate when moving, and then the other side of the packaging box continues to move.
