[Specific implementation method]

[0029] Example 1:

[0030] Please refer to Figure 1-Figure 7The present embodiment is an automatic double-sided labeling device 100 for large and small combination bottles, which includes a feeding conveyor line 1, a labeling conveyor line 2 arranged parallel to the feeding conveyor line 1, a loading and transporting mechanism 3 for transporting large and small bottles from the feeding conveyor line 1 to the labeling conveyor line 2, a labeling unit 4 arranged along the labeling conveyor line 2, an auxiliary labeling module 5, a visual inspection unit 6 and a unloading and transporting mechanism 7, and a plurality of material receiving boxes 8 arranged at the end of the labeling conveyor line 2; the labeling unit 4 includes a first labeling module 41 and a second labeling module 42 arranged on the left and right sides of the labeling conveyor line 2, which automatically label the left and right surfaces of the bottle body 200 respectively.

[0031] Bottle holders 21 are arranged at equal intervals on the labeling conveyor line 2 , and a bearing groove (not marked in the figure) that is shaped like the bottle body 200 is provided in the bottle holder 21 .

[0032] The loading and handling mechanism 3 includes a first drive module 31, a first support plate 32 driven by the first drive module 31 for left-right movement, a first cylinder 33 fixed to the first support plate 32, a second support plate 34 driven by the first cylinder 33 for up-and-down movement, and a plurality of first gripper assemblies 35 equally spaced along the front-to-back direction on the second support plate 34. The spacing between adjacent first gripper assemblies 35 on the second support plate 34 corresponds to the spacing between adjacent bottle holders 21 on the labeling conveyor line 2. The first gripper assemblies 35 include a gripper cylinder 351 fixed to the second support plate 34 and gripper jaws 352 driven by the gripper cylinder 351 to open or clamp.

[0033] The tail section of the feeding conveyor line 1 is provided with a plurality of stop assemblies 11. The two bottles stopped by two adjacent stop assemblies 11 correspond to the distance between two adjacent bottle holders 21 on the labeling conveyor line 2. The plurality of stop assemblies 11 together stop a group of bottles for the feeding and conveying mechanism 3 to take away.

[0034] The first labeling module 41 and the second labeling module 42 can adopt existing labeling structures on the market, and have the functions of automatic label feeding, automatic label pasting, and automatic backing paper recycling.

[0035] Because the labeling unit 4 applies labels to the left or right side of the bottle 200, and the majority of the bottle 200 protrudes upward from the loading slot, with no perimeter barrier around this exposed portion, the bottle 200 can be easily pushed sideways during side labeling, resulting in incomplete labeling. Therefore, to address this issue, this embodiment provides side guard assemblies 43 on the labeling conveyor line 2 at locations corresponding to the first labeling module 41 and the second labeling module 42. The side guard assemblies 43 include side guards 431 positioned opposite the first or second labeling module 41, 42, and an upper guard 432 that limits the height above the bottle. The side baffle 431 includes a support portion 4311 that supports the opposite surface of the bottle while the first or second labeling module 41, 42 is labeling the bottle. Guide portions 4312 are located on the side baffle 431, located on both sides of the support portion 4311. When a bottle 200 is placed in the bottle holder 21, the guide portions 4312 guide and limit the bottle's side surface as the labeling conveyor line 2 moves to the labeling position. When the bottle 200 stops moving, the bottle's side surface is precisely against the support portion 4311. When the first or second labeling module 41, 42 is labeling the other side of the bottle 200, the support portion 4311 prevents the bottle from being pushed sideways or tilted, thereby ensuring that the label is fully and securely attached to the bottle surface. The upper baffle 432 is primarily used to prevent the bottle from being lifted off the bottle holder 21 during labeling.

[0036] In this embodiment, a label 300 is attached to each of the left and right surfaces of the bottle body 200. In addition to the main areas 301 attached to the left and right surfaces of the bottle body 200, the label 300 on one side also includes a small adhesive area 302 attached to the upper surface of the bottle body 200, and the label 300 on the other side also includes a small adhesive area 303 attached to the upper surface of the bottle body 200.

[0037] The auxiliary labeling module 5 includes a first auxiliary labeling assembly 51 and a second auxiliary labeling assembly 52, which are arranged on the left and right sides of the labeling conveyor line 2. The first auxiliary labeling assembly 51 and the second auxiliary labeling assembly 52 are used to respectively adhere the small patch adhesive area 302 and the small strip adhesive area 303 to the upper surface of the bottle body 200.

[0038] The first auxiliary labeling assembly 51 includes a second cylinder 511, a third support plate 512 that is driven by the second cylinder 511 to move left and right, and a plurality of rolling wheels 513 rotatably mounted on the third support plate 512 and evenly spaced along the conveying direction of the labeling conveyor line 2. The plurality of rolling wheels 513 simultaneously roll and label the small adhesive areas 302 on multiple bottles.

[0039] The second auxiliary labeling assembly 52 includes a third cylinder 521, a fourth cylinder 522 driven by the third cylinder 521 to move up and down, a fourth support plate 523 driven by the fourth cylinder 522 to move left and right, and several pressing assemblies 524 arranged at equal intervals along the front-to-back direction on the fourth support plate 523 to affix the small labeling area 303 to the upper surface of the bottle. The pressing assembly 524 includes a fixed pressing block 5241 fixed to the fourth support plate 523, a fifth cylinder 5242, and a movable pressing block 5243 driven by the fifth cylinder 5242 to move up and down. Part of the small strip pasting area 303 is pasted on the upper surface of the large bottle, and the other part is pasted on the upper surface of the small bottle. After the large and small bottles are combined, there may be production height errors or combination assembly errors, which will result in the upper surfaces of the large and small bottles not necessarily being flush after the combination. Therefore, by combining a fixed pressing block 5241 and a movable pressing block 5243, the fixed pressing block 5241 is used to push and press the part pasted on the upper surface of the large bottle through a horizontal pushing motion, and the movable pressing block 5243 is used to press and paste the part pasted on the upper surface of the small bottle through an up and down movement, thereby pasting the entire small strip pasting area 303 as a whole to the upper surfaces of the large and small bottles.

[0040] To ensure smooth and accurate application of the small block and strip adhesive areas 302 and 303, a positioning module 53 is installed on the labeling conveyor line 2 at the location corresponding to the auxiliary labeling module 5 to fix the position of the large and small bottles. The positioning module 53 is located below the first auxiliary labeling assembly 51 and includes a sixth air cylinder 531, a fifth support plate 532 driven by the sixth air cylinder 531 for left-right movement, and several clamping assemblies 533 arranged at equal intervals along the front-to-back direction on the fifth support plate 532. The clamping assemblies 533 include a seventh air cylinder 5331 fixed to the fifth support plate 532 and clamping plates 5332 driven by the seventh air cylinder 5331 to open and clamp forward and backward.

[0041] Each of the large and small bottles 200 is correspondingly equipped with a clamping assembly 533 , a rolling wheel 513 and a pressing assembly 524 , and the small block pasting area 302 and the small strip pasting area 303 are precisely pasted through the cooperation of the above three.

[0042] The visual inspection unit 6 includes a first camera 61 for inspecting whether the labels on the large and small bottles 200 are correctly affixed, and a pair of second cameras 62 for inspecting whether the labels on the left and right sides of the large and small bottles 200 are correctly affixed.

[0043] The material unloading and handling mechanism 7 includes a second driving module 71, a sixth support plate 72 driven by the second driving module 71 to move left and right, an eighth cylinder 73 fixed on the sixth support plate 72, and a second clamping jaw assembly 74 driven by the eighth cylinder 73 to move up and down.

[0044] The material receiving box 8 includes a pair of first material receiving boxes 81 located on the left and right sides of the labeling conveyor line 2 and below the transfer range of the second clamping jaw assembly 74 , and a second material receiving box 82 located at the end of the labeling conveyor line 2 .

[0045] In this embodiment, the eighth cylinder 73 and the second clamping jaw assembly 74 constitute a group of blanking clamping modules, and two of the blanking clamping modules are provided on the sixth support plate 72, corresponding to the above-mentioned pair of first receiving boxes 81 respectively. According to the defective results detected by the visual inspection unit 6, if the labeling on the left or right sides is poor, it is placed in the first receiving box 81 on the left; if the labeling on the top is poor, it is placed in the first receiving box 81 on the right; if it is qualified, it is transported to the end along the labeling conveyor line 2 and automatically falls into the second receiving box 82.

[0046] The working principle of the large and small combination bottle double-sided automatic labeling equipment 100 of this embodiment is as follows: large and small bottles 200 are fed through the feeding conveyor line 1, and the stopping component 11 stops a group of large and small bottles 200 with a set spacing at the end of the feeding conveyor line 1, and then the feeding conveying mechanism 3 transports them to the labeling conveyor line 2 and accurately places them in the bottle holder 21; the labeling conveyor line 2 transports the large and small bottles 200 forward, and when passing through the labeling unit 4, the first labeling module 41 and the second labeling module 42 are used to label the large and small bottles 200. 0 are pasted with labels 300 on both sides; then they move to the auxiliary labeling module 5, and the small block pasting area 302 and the small strip pasting area 303 are pasted by the first auxiliary labeling component 51 and the second auxiliary labeling component 52; in this embodiment, the auxiliary labeling module 5 is provided with two groups to improve the labeling efficiency; after the labeling is completed, the large and small bottles 200 move through the visual inspection unit 6 to complete the automatic inspection of the labeling area, and finally the unloading and handling mechanism 7 is used to classify and unload them according to the labeling inspection results.

[0047] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
