Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1 to 6 This utility model will be described in detail.

[0023] This utility model relates to an automatic labeling device for packaging cartons, comprising a machine base 1, on which a conveying mechanism 2, a label feeding mechanism 3, a labeling mechanism 4, a vision recognition system 5, and a control system 6 are provided; the conveying mechanism 2 is used to convey cartons; the label feeding mechanism 3 is disposed on one side of the labeling mechanism 4 and is used to provide label paper to the labeling mechanism 4; the vision recognition system 5 is installed on the labeling mechanism 4; the labeling mechanism 4 is used to affix labels; the conveying mechanism 2, the label feeding mechanism 3, the labeling mechanism 4, and the vision recognition system 5 are all electrically connected to the control system 6.

[0024] The working principle of this utility model is as follows: the carton is transported to the labeling station by the conveying mechanism 2, and at the same time, the labeling mechanism 4 starts and picks up the label from the label feeding mechanism 3. Then, the vision recognition system 5 identifies the label pasting position of the carton in real time and transmits the position information to the control center. After the labeling position is accurately located, the labeling mechanism 4 affixes the label to the top surface of the carton. The main advantages of this utility model are: it realizes fully automated label pasting, with a high degree of automation, replacing traditional manual processing and doubling the labeling efficiency; in addition, the labeling head 41, the vision recognition system 5, and the control system 6 work together to ensure that this utility model can always accurately identify the label pasting position, resulting in high label pasting accuracy and a high yield rate.

[0025] In one embodiment, the conveying mechanism 2 includes a conveyor belt 21, and a pressure sensor 22 is disposed below the conveyor belt 21. The carton enters the working area via the conveying mechanism 2, the pressure sensor 22 detects its position, and transmits data such as length, width, and height to the control system 6.

[0026] Preferably, the conveying mechanism 2 further includes an alignment mechanism 7, which includes a first alignment component 71 and a second alignment component 72 disposed opposite to each other. The first alignment component 71 and the second alignment component 72 cooperate with each other to further position the carton after the conveyor belt 21 stops conveying, so that the labeling mechanism 4 can better apply the label.

[0027] As one embodiment, the first alignment component 71 and the second alignment component 72 both include a mounting base 73 and an alignment cylinder 74 and an alignment plate 75 disposed on the mounting base 73; the alignment cylinder 74 drives the alignment plate 75 to move, and the alignment plate 75 positions the side of the carton.

[0028] In another embodiment, the label feeding mechanism 3 includes an unwinding mechanism 31, a winding mechanism 32, and a conveyor roller group 33 and a peeling plate 34 disposed between the unwinding mechanism 31 and the winding mechanism 32; the unwinding mechanism 31 is used to unwind the label; the winding mechanism 32 is used to wind the label backing paper; the conveyor roller group 33 assists in conveying the label and the label backing paper; the peeling plate 34 is used to peel the label from the backing paper. The peeling plate 34 has two embodiments, one of which is as follows... Figure 4 As shown, the peeling plate 34 is disposed on the inner side of the label paper and has a pointed tip. Utilizing the fact that the label paper is harder than the backing paper, it pushes the label out of the backing paper. In this embodiment, because the peeling plate 34 is disposed on the inner side of the label paper, it is less likely to scratch the surface of the label paper. Secondly, as... Figure 6 As shown, the peeling plate 34 can be set on the outside of the label paper. The peeling plate 34 is an elastic structure that peels the edge of the label out of the backing paper through its tip, thereby achieving the purpose of peeling and removing the label.

[0029] Preferably, a photoelectric sensor 35 is installed above the peeling plate 34. The photoelectric sensor 35 is used to detect whether the label is peeled off in time, preventing situations such as material shortage in the labeling mechanism 4 and failure to label the carton.

[0030] like Figure 2 As shown, the labeling mechanism 4 includes a labeling head 41 and a triaxial linear module 42 that drives the labeling mechanism 4 to move; the visual recognition system 5 is disposed on both sides of the labeling head 41; at least two vacuum suction cups 43 are installed at the bottom of the labeling head 41. The triaxial linear module 42 drives the labeling head 41 to move. After the vacuum suction cups 43 move to the conveying mechanism 2 to pick up the label, the labeling head 41 moves to the top of the carton. The visual recognition system 5 on both sides of the labeling head 41 locates the labeling position in real time. After positioning, the label is directly affixed to the top surface of the carton.

[0031] This invention also includes a rolling mechanism 8, which is located on the other side of the labeling mechanism 4. After the carton is labeled, it passes through the rolling mechanism 8, which rolls and flattens the labeled carton again to improve the label adhesion quality.

[0032] Preferably, the rolling mechanism 8 includes a drive cylinder 81, a telescopic arm 82, and a swing frame 83 connected in sequence; a rolling wheel 84 is movably mounted at the front end of the swing frame 83. When the rolling mechanism 8 is activated, the drive cylinder 81 drives the telescopic arm 82 to extend forward, causing the rolling wheel 84 to roll over the carton label, flattening the label and adhering it to the top surface of the carton. Adjustments to the roller angle and height can be made by swinging the swing frame 83.

[0033] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
