The disordered merging component 50 is connected to the two conveyor lines 3 70. The disordered merging component 50 is used to disorderly scramble the multiple medium packaging boxes transported by the conveyor line 3 70. The disordered merging component 50 is connected to the packaging assembly line 80. The blind box packaging method includes the following steps:

[0043] S1, one cartoning machine assembly line 10 puts the hidden toys into a single packaging box to form a hidden blind box, and the other cartoning machine assembly lines 10 put the regular toys into a single packaging box to form a regular blind box, and the multiple cartoning machine assembly lines 10 convey the regular blind boxes and the hidden blind boxes to multiple conveyor lines 11 respectively;

[0044] S2, multiple conveyor lines 11 convey regular blind boxes and hidden blind boxes to the classification transmission device 20, and transfer a specific number of regular blind boxes and one hidden blind box to a classification transmission line 26 through the receiving suction component;

[0045] S3, the conveyor line 2 60 receives the blind boxes from the classification transmission line 26, and conveys the blind boxes to the disordered material pushing structure 30 via the conveyor line 2 60, and the order of the blind boxes is disrupted by the disordered material pushing structure 30;

[0049] The disordered material pushing structure 30 includes a disordered material pushing and conveying structure and a conveying and turning material structure. The tail end of the disordered material pushing structure is connected to the conveying and turning material structure. The disordered material pushing and conveying structure is used to intersperse the blind boxes and disrupt the order of the blind boxes. The conveying and turning material structure is used to adjust the state of the blind box and allow the blind box to smoothly enter the interior of the middle box machine 40.

[0050] The disordered material pushing and conveying structure includes a frame 31, a second conveyor belt 32, a third conveyor belt 33 and an electric push rod 34. The second conveyor belt 32 and the third conveyor belt 33 are both connected to the frame 31. The second conveyor belt 32 and the third conveyor belt 33 are arranged in parallel. The conveying directions of the second conveyor belt 32 and the third conveyor belt 33 are parallel. The conveying surfaces of the second conveyor belt 32 and the third conveyor belt 33 are on the same horizontal plane. There are multiple electric push rods 34, and the multiple electric push rods 34 are arranged along the conveying direction of the second conveyor belt 32. The moving direction of the output end of each electric push rod 34 is perpendicular to the conveying direction of the second conveyor belt 32. The multiple electric push rods 34 perform telescopic movements without a fixed order.

[0051] In actual use, the blind boxes are first placed on the conveyor belt 2 32 to ensure that each blind box corresponds to an electric push rod 34, and the electric push rods 34 are randomly started by controlling an appropriate number of them. The corresponding blind boxes are pushed from the conveyor belt 2 32 to the conveyor belt 33 by moving the output ends of the started electric push rods 34, so that the blind boxes are pushed in an disorderly manner, and the remaining blind boxes on the conveyor belt 2 32 fill the vacant spaces after being pushed out under the action of the conveyor belt 2 32, and new blind boxes are added to fill the remaining spaces, so that the feeding operation can be continuously performed on the conveyor belt 33, so that the order of the blind boxes can be disrupted and the blind boxes can be transported.

[0052] It should be noted that the random start-up of multiple electric push rods 34 is controlled by an external computer program, and the output end of the electric push rod 34 is connected to a push plate made of rubber material, which can prevent the surface of the blind box from being scratched when pushing the blind box, and a structure for blocking the blind box is provided at the end position of the conveyor belt 2 32 to prevent the blind box from falling from the conveyor belt 2 32.

[0053] The conveying and turning structure includes a conveyor belt 4 35, a flipping belt 36, a baffle 37 and a guide rod 38. The conveyor belt 4 35 is connected to the conveyor belt 3 33 end to end, and the conveying directions of the conveyor belt 4 35 and the conveyor belt 3 33 are parallel to each other. The end of the conveyor belt 4 35 corresponds to the position of the feed port of the cartoning machine 81. The flipping belt 36 is arranged on one side of the conveyor belt 4 35. The flipping belt 36 is inclined. The transmission reverse direction of the flipping belt 36 is parallel to the conveying direction of the conveyor belt 4 35. The flipping belt 36 is used to change the blind box from a horizontal state to a longitudinal state. The baffle 37 is arranged on the conveyor belt 4 35. The baffle 37 corresponds to the position of the flipping belt 36. An L-shaped fixed frame is arranged on the frame 31. The guide rod 38 is connected to the fixed frame. The end of the guide rod 38 close to the flipping belt 36 is set to an inclined state, and the rest of the guide rod 38 away from the flipping belt 36 is set to a horizontal state. The guide rod 38 is used to guide the blind box during the flipping process so that the blind box can be more smoothly transformed from horizontal placement to longitudinal placement.

[0054] The blind box on conveyor belt three 33 will be conveyed to conveyor belt four 35. As conveyor belt four 35 drives the blind box to move, the blind box first contacts the bottom end of the flip belt 36, and as conveyor belt four 35 and flip belt 36 are conveyed, the blind box is gradually lifted on the flip belt 36. When the blind box moves to the end position of the flip belt 36, the blind box is stood up under the action of the guide rod 38, so that it changes from horizontal placement to vertical placement on conveyor belt four 35, thereby facilitating the subsequent box loading operation of the middle box machine 40.

The moving directions of the output ends of the two cylinders 54 are opposite, and the moving directions of the output ends of the two cylinders 54 are perpendicular to the conveying direction of the conveyor belt 51, and the two cylinders 54 have no fixed order of telescopic movement.

[0057] By disorderly controlling the start of the two cylinders 54, the two blind box pushing plates 56 can be moved disorderly, and the medium packaging boxes inside the two medium packaging box conveying channels can be pushed to the middle position of the conveyor belt 51 through the disorderly movement of the blind box pushing plates 56.

[0058] It should be noted that the disorderly start-up of the two cylinders 54 is controlled by an external computer program, so that the medium-sized packaging boxes can be pushed randomly, thereby randomly disrupting the order of the medium-sized packaging boxes, and the two cylinders 54 will not work at the same time. Only after one cylinder 54 completes its work and resets will it continue to the next pushing operation.

[0059] The lifting and conveying structure includes a lifting conveyor belt 57 and a baffle plate. There are two baffle plates, which are symmetrically arranged on the lifting conveyor belt 57.

The blind box conveying channels 22 correspond one-to-one with the conveying lines 11, thereby facilitating the blind boxes on the conveying lines 11 to smoothly enter the interior of the blind box conveying channels 22.

[0061] The transfer assembly includes an installation frame 23, to which a displacement structure 24 is connected, and to which a vacuum suction cup assembly 25 is connected.
