When the pressure reaches the set value, it proves that the material carton 12 has completed the centering process, that is, the servo motor 118 is stopped. The types and sizes of the material cartons 12 are different, so the centering movement stroke of the clamping centering plate 1110 is also different. The spring pressure sensor 1111 can automatically control the centering of material cartons 12 of different types, and the versatility is greatly improved. This overall design structure drives the bidirectional transmission screw 117 to rotate through the servo motor 58, so that the two screw sliding blocks 119 are simultaneously moved toward the center, and the material is centered and clamped through the clamping centering plate 1110.

[0029] In this embodiment, a lifting and rotating device 14 is provided at the lower end of the rotating base plate 111, and the lifting and rotating device 14 includes a lifting base plate 141, a lifting plate 142, a lifting cylinder 143, a lifting rod 144 and a rotating platform 145. The lifting cylinder 143 is installed at the lower end of the lifting base plate 141, and the lifting plate 142 is located above the lifting base plate 141. A lifting guide column 146 is provided between the lifting plate 142 and the lifting base plate 141. One end of the lifting rod 144 passes through the base plate and the lifting plate 142. The rotating platform 145 is connected to each other, and is installed on the upper end of the lifting plate 142, and the rotating base plate 111 is installed on the upper end of the rotating platform 145; this design is used to drive the rotating platform 145 and the centering and positioning mechanism 11 to rise at the same time through the lifting cylinder 143.

[0030] In this embodiment, there are two vertical stands 3 provided on the first frame 1, and the label printer 4 is mounted upside down on each of the vertical stands 3. There are also two labeling robots 6 and first CCD cameras 7 provided on the first frame 1, and there are also two centering positioning mechanisms 11 provided on the conveying frame 2.

[0031] In this embodiment, a sub-label collecting cylinder 15 is further provided on the first frame 1. The sub-label collecting cylinder 15 is located within the moving range of the labeling robot 6. The sub-label collecting cylinder 15 is used to collect the sub-labels printed by the label printer 4. By setting two independently controlled vacuum suction areas on the vacuum suction cup 8, the label 41 and the sub-label are sucked respectively. When the sub-label collecting cylinder 15 is moved by the labeling robot 6, the suction of the sub-label suction area is closed, and the sub-label falls into the sub-label collecting cylinder 15.

[0034] In this embodiment, the working process of the present invention is as follows: after the material carton is fed and scanned by the material scanner, the two label printers 4 print out different labels 41 at the same time. After the incoming material sensor 21 senses the incoming material, the material stopper lifter 22 rises to block the material carton 12, and then the centering and positioning mechanism 11 centers and positions the material carton 12. At the same time, the two labeling robots 6 respectively take away the labels 41 printed by the two label printers 4, and then move to the first CCD camera 7 to take pictures to locate the position of the label 41 on the vacuum suction cup 8, and then move to the side of the material carton 12, and use the second CCD camera 9 to take pictures to determine the position of the label attachment area 13. Then, the coordinate information captured by the first CCD camera 7 and the second CCD camera 9 is used to control the labeling robot 6 to accurately stick the label on the label attachment area 13, and then the roller brush 62 is used to roll and press the stuck label. Then the material carton 12 moves forward to the second centering positioning mechanism 11. If the material carton 12 only needs different labels on the same side, the label 41 can be directly attached to the material carton 12 by the second labeling robot 6. If the material carton 12 needs to have labels 41 attached on different sides, the material carton 12 is rotated and turned over by the jacking and rotating device 14, and then labeled by the second labeling robot 6.
