[0001] The present invention relates to the technical field of sorting equipment, and in particular to an automatic sorting device for packaging boxes. Background Art

[0002] In logistics centers, warehouses, manufacturing plants and other places, sorting equipment based on industrial cameras usually automatically identifies and sorts packaging boxes of different types, sizes and destinations. Specifically, industrial cameras are used to capture the barcode, QR code or label information on the packaging boxes, and the information is identified through image processing technology. Then, the control system directs the actuator to complete the sorting action.

[0003] Traditional packaging boxes are mixed with other packaging bags and placed on a conveyor table. The boxes and packaging bags are then manually picked up and placed on several sorting devices. When placing the boxes, in order to facilitate the industrial camera above the sorting equipment to recognize the label information, the side with the information label needs to be placed upwards. Especially for packaging boxes with large mass or volume, the sorting staff needs to pick up the box, quickly observe and flip it to adjust the information label to face upwards, and then place it on the conveyor table of the sorting equipment.

After the packaging box body 100 is identified, the packaging box body 100 slides from the receiving mechanism 6 to the top of the conveying roller D71. The multiple conveying rollers D71 are driven to rotate by external force, driving the packaging box body 100 to move. According to the information of the packaging box body 100, after moving to the position where unloading is required, the pushing plate 742 is driven to move by the electric push rod B741, pushing the packaging box body 100, so that the packaging box body 100 falls from the corresponding unloading plate 73.

A support base 18 is provided at the bottom of the protective shell 16 for supporting the equipment.

[0034] Principles and advantages of automatic sorting device for packaging boxes: When the equipment is in use, the packaging box body 100 is transported to the conveying platform A1, and the driving motor A11 drives the gear box A12 to operate, thereby driving the multiple conveying rollers A13 to rotate, and transporting the packaging box body 100 to the bottom of the recognition camera A21. The recognition camera A21 of the top recognition mechanism 2 recognizes the packaging box body 100. If the recognition camera A21 recognizes the information, the packaging box body 100 continues to be transported, so that the packaging box body 100 falls from between the two rows of conveying rollers B41 to the receiving mechanism 6, and the multiple conveying rollers C61 rotate to drive the packaging box body 100 to move, so that the packaging box body 100 falls on the top of the multiple conveying rollers D71. The multiple conveying rollers D71 are driven to rotate by external force, driving the packaging box body 100 to move. After moving to the position where the material needs to be unloaded according to the information of the packaging box body 100, the electric push rod B741 drives the pushing plate 742 to move, pushing the packaging box body 100, so that the packaging box body 100 falls from the corresponding unloading plate 73; Its advantage is that the identification camera A21 replaces manual identification of the information on the top of the packaging box body 100, and the packaging box body 100 can be classified and placed according to the identified information. The staff only needs to place the packaging box body 100 on top of multiple conveying rollers A13, which reduces the labor intensity of the staff.

[0035] If the recognition camera A21 does not recognize the information, the two threaded rods A153 are driven to rotate by the two driving motors B152, and the two moving frames 151 are driven to move, so that the two correction belts 157 are close to the two sides of the packaging box body 100, and the two sprockets A154 are driven to rotate by the two threaded rods A153, thereby driving the two chains 155 to rotate, and driving the two correction belts 157 to rotate. The two correction belts 157 are tilted so that the bottom running directions of the two correction belts 157 are opposite. The two correction belts 157 contact the two sides of the packaging box body 100, and apply a force in opposite directions to the two sides of the packaging box body 100, so that the tilted packaging box body 100 is close to the two sides of the packaging box body 100. The box body 100 rotates and is corrected; at the same time, the drive motor D421 drives a drive rod 422 and a threaded rod B425 to rotate, the drive rod 422 drives a pulley 423 to rotate, the pulley 423 drives another pulley 423 to rotate through a belt 424, the two pulleys 423 drive the corresponding two threaded rods B425 to rotate, the corresponding drive rods 422 drive the corresponding threaded rods B425 to rotate, so that the four threaded rods B425 rotate together, driving the two threaded movable plates 426 to move relative to each other, thereby driving the two rows of conveyor rollers B41 to move relative to each other, so that the two rows of conveyor rollers B41 can support the transport packaging box body 100; The packaging box body 100 is transported by multiple conveyor rollers A13 and moves to the top of the two rows of conveyor rollers B41. Then, the support frame B32 is driven downward by two electric push rods A34, which can drive the four recognition cameras B31 to move downward, thereby performing information recognition on the side of the packaging box body 100. If the information of the packaging box body 100 is recognized, the driving motor D421 is used to reversely drive the two rows of conveyor rollers B41 to reset, so that the packaging box body 100 falls from the middle of the two rows of conveyor rollers B41 to the top of the receiving mechanism 6. The packaging box body 100 is driven to move by the rotation of multiple conveyor rollers C61, so that the packaging box body 100 falls on the top of multiple conveyor rollers D71. The multiple conveyor rollers D71 are driven to rotate by external force, driving the packaging box body 100 to move. According to the information of the packaging box body 100, after moving to the position where unloading is required, the electric push rod B741 drives the pushing plate 742 to move, pushing the packaging box body 100, so that the packaging box body 100 falls from the corresponding unloading plate 73.

[0036] Its advantage is that the two correction belts 157 are set at an angle, so that the packaging box body 100 can be rotated and corrected, which is convenient for the subsequent side identification mechanism 3 to identify the side information of the packaging box body 100, and the correction belt 157 is set at an angle, which saves more space on the inner side of the conveyor platform A1 than the horizontal setting of the correction belt 157. The supporting mechanism 4 can support the packaging box body 100 when detecting the side information of the packaging box body 100, and can release the support for the packaging box body 100 after detecting the information of the packaging box body 100, which is convenient for subsequent transportation. Through the setting of the side identification mechanism 3, the information on the side of the packaging box body 100 can be identified without manual identification.

[0037] If the four recognition cameras B31 do not recognize the information, the two electric push rods A34 continue to drive the support frame B32 to move downward, thereby driving the connecting rod 53 to move downward, so that the driving tooth 531 contacts the gear 52 and drives the gear 52 to rotate. The rotation of the gear 52 drives the recognition camera C51 to rotate, thereby driving the sliding pin 511 to slide inside the sliding groove 631 through the sliding pin 511, driving the receiving mechanism 6 to slide to one side, making room for the detection position for the recognition camera C51, and the recognition camera C51 rotates to be parallel to the packaging box body 100, and recognizes the bottom of the packaging box body 100. After recognizing the information, the electric push rod A34 drives the support frame B32 to move upward to drive the teeth 531 and the sliding pin 511. Pin 511 drives the identification camera C51 and the receiving mechanism 6 to reset, and then drives the motor D421 to run in the opposite direction, driving the two rows of conveying rollers B41 to reset, so that the packaging box body 100 falls from the middle of the two rows of conveying rollers B41 to the top of the receiving mechanism 6, and the multiple conveying rollers C61 rotate to drive the packaging box body 100 to move, so that the packaging box body 100 falls on the top of the multiple conveying rollers D71. The multiple conveying rollers D71 are driven to rotate by external force, driving the packaging box body 100 to move. According to the information of the packaging box body 100, after moving to the position where unloading is required, the electric push rod B741 drives the pushing plate 742 to move, pushing the packaging box body 100, so that the packaging box body 100 falls from the corresponding unloading plate 73.

[0038] Its advantage is that when the recognition camera A21 and the four recognition cameras B31 fail to recognize the information of the packaging box body 100, the recognition camera C51 is used to recognize the bottom of the packaging box body 100, and then subsequent classification and unloading are carried out without manual sorting, which reduces the workload of the staff. In addition, the recognition camera C51 is placed vertically on the conveyor platform A1 before recognition to prevent dust on the packaging box body 100 from falling onto the recognition camera C51 when not in use, thereby affecting subsequent recognition work.

[0039] It is worth mentioning that the above sorting method has the following advantages: Advantage 1: Through the recognition of recognition camera A21, four recognition cameras B31 and recognition camera C51, the information of the packaging box body 100 can be entered without manual flipping and adjustment of the packaging box, and the packaging box body 100 can be automatically classified and placed through the classification mechanism 7, reducing the workload of the staff.

[0040] The second advantage is that when the recognition camera A21 fails to recognize the information of the packaging box body 100, the two correction belts 157 can drive the two sides of the packaging box body 100 to rotate, so that the packaging box body 100 can be rotated and corrected, which facilitates the four recognition cameras B31 to recognize the side information of the packaging box body 100, and prevents the packaging box body 100 from not being able to recognize the side information label due to the placement angle problem.

[0041] Advantage three: when the recognition camera A21 fails to recognize the information of the packaging box body 100, the two electric push rods A34 drive the four recognition cameras B31 to identify and detect the side of the packaging box body 100. When the recognition camera A21 and the four recognition cameras B31 fail to recognize the information of the packaging box body 100, the gear 52 drives the recognition camera C51 to rotate, so that the recognition camera C51 recognizes the bottom of the packaging box body 100, reducing the number of times the four recognition cameras B31 and the recognition camera C51 are used, thereby increasing the service life of the four recognition cameras B31 and the recognition camera C51.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
