Of course, on the basis of the two detection units of the embodiment, the detection from different directions is better than the acquisition of the body crease mark information by continuously adding a plurality of detection units, but the corresponding required space is larger, and the specific number and the specific arrangement mode can be determined according to the site construction environment.
The sensing detection unit in the device can be a photoelectric sensor, is connected with each camera, is arranged along the conveying direction of the bottle body, can detect the passing of the bottle body, and then sends a trigger signal to the cameras to take a picture. The image processing unit is connected with each camera, can process the bottle label image shot by the camera, and judges whether the current bottle label has a crease label according to image information.
The following is a detailed description of specific unit deployments:
the conveying unit 1 adopts a common bottle conveying assembly line, which can be multiple groups, so that at least half bottle intervals exist among bottles conveyed to the detection equipment.
The guiding unit 2 is located above the conveying unit 1, guiding ports are formed in the front and the back, and when high-speed conveying can be guaranteed, bottle opening and bottle cap areas can be guided by the guiding unit 2, and the bottle can accurately enter the bottle rotating unit 3.
The bottle rotating unit 3, see fig. 1, comprises two bottle clamping belts which are horizontally arranged, rotate respectively through motor control and are located above the conveying unit 1, and the two bottle clamping belts can clamp the upper portion of the bottle body to rotate through different rotating speeds, so that the bottle body label is completely exposed outside. The bottle body can be guaranteed to rotate at a constant speed while walking when being linearly conveyed, and the rotation of the bottle body is larger than 360 degrees from the inlet to the outlet.
The first detecting unit 4 and the second detecting unit 5 are sequentially disposed on both upstream and downstream sides of the lower portion of the bottle turning unit 3.
Wherein the first detection units 4, including two, are symmetrically arranged at both sides of the conveying unit 1, and each first detection unit 4 includes a first light source 41, a first mirror 42, and a first camera 43.
As shown in fig. 2, each first detection unit 4 includes two first light sources 41 arranged opposite to each other therein. One of which is located upstream of the conveyor line and the other of which is located downstream of the conveyor line and is located below the bottle clamping belt. The two first light sources 41 are vertically arranged, perpendicular to the bottle conveying direction, and abut against the conveying unit 1. Thus, the vertical label contents of the front half 90 degrees and the rear half 90 degrees of the bottle body can be illuminated successively. And the bottle body can be illuminated by 360 degrees through the two first detection units 4 which are oppositely arranged, so that dead angle detection is avoided. And then the bottle body is continuously rotated by matching with the bottle rotating unit 3, the plurality of first cameras 43 can obtain label images of a plurality of angles, and then the fold information of the whole label outside the bottle body can be obtained.
Because the bottle body is polished from the side face, the camera shoots an image in the interval and the image is processed by the image processing unit, so that whether the vertical wrinkles exist in the vertical area can be easily judged.
In order to avoid mutual interference when the two first light sources 41 are lighted, the wave bands of the two first light sources 41 are set to be different, and the camera lens is matched with the filter lenses with the same wave band, so that the mutual interference among the light sources symmetrically arranged on the same side can be reduced, and the quality of the image is improved.
Further, the first reflecting mirror 42 is disposed outside the two first light sources 41 with a tilt of 45 degrees, over which a plurality of cameras are disposed.

Because of the attenuation of light, the body is illuminated only from the upper or lower portion, and the distant image is blurred, two second light sources 51 are included in each second detection unit 5, which are arranged opposite to each other from above and below. The lower second light source 51 is lower than the body label, and the upper second light source 51 is fixed at the lower part of the bottle clamping belt. The upper light source is used for polishing downwards the folds of the label of the upper half part of the bottle body, and the lower light source is used for polishing upwards the folds of the label of the lower half part of the bottle body. Therefore, the bottle body is illuminated through vertical lighting, and the camera shoots an image in the interval and can easily judge whether transverse wrinkles exist in the area after the image is processed by the image processing unit.
In order to avoid mutual interference when the two second light sources 51 are lighted, the two second light sources 51 are set to be lighted at intervals, the light source wave bands are different, and the camera lens is matched with the filter lenses with the same wave band, so that the mutual interference among the light sources symmetrically arranged at the same side can be reduced, and the quality of images is improved.
Referring to fig. 2, the arrangement of the second mirror 52 and the second camera 53 outside the second light source 51 is the same as the first mirror 42 and the first camera 43, and will not be described again here.
By arranging the first light source 41 of the first detection unit 4 and the second light source 51 of the second detection unit 5 to be perpendicular to each other, vertical wrinkles or lateral wrinkles of the body label can be effectively detected. Through setting up two respectively with first detecting element 4 and second detecting element 5 above, symmetrical arrangement is in conveying element 1 both sides, can compress this detection device's occupation of land space greatly to improve detection speed, the convenient arrangement in the workshop.
