Detailed description of the invention
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.
Fig. 1 is the flow chart of aluminium-foil paper provided in an embodiment of the present invention and inner box paper detection method.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
As shown in Figure 1, the embodiment of the invention provides a kind of aluminium-foil papers and inner box paper detection method comprising following step
It is rapid:
Step S1, the image for adjusting image acquisition unit obtains direction, so that image obtains on direction and cigarette package line
Target position be overlapped.
Wherein, which is the position of the aluminium-foil paper and inner box paper that can observe that cigarette is wrapped simultaneously, it is possible thereby to
The status information of aluminium-foil paper and inner box paper is read in the cigarette packet image of acquisition.
Step S2, real image of the cigarette packet for being enclosed with aluminium-foil paper and inner box paper on cigarette package line is obtained.
Step S3, real image is compared with preset standard picture, and exports comparison result.
Wherein, it is image under eligible state which, which is the quality of aluminium-foil paper and inner box paper that cigarette is wrapped, with this
Reference as above-mentioned real image.In addition, image recognition, image can be passed through between the real image and standard picture that obtain
Algorithm and gray proces are compared.
Step S4, the cigarette packet of aluminium-foil paper and inner box paper is enclosed with the presence or absence of mass defect according to comparison result judgement；Such as
Fruit is to enter step S5.
Step S5, it is rejected from cigarette package line by the cigarette packet that quality problems will be present in PLC control device for eliminating.Its
In, device for eliminating can be cylinder, and defective cigarette packet can will be present by the movement of cylinder and reject cigarette package line.
Specifically, step S3 is specifically included:
Step S31, according to standard picture established standards gray value.
Step S32, actual grey value is obtained according to real image and standard picture.
Step S33, judge whether actual grey value is above standard gray value；If so, entering step S34.
Step S34, there are mass defects for the cigarette packet for determining in real image, and export defect cigarette packet signal.
Wherein, if aluminium-foil paper or inner box paper existing defects, can obviously occur in the gray value of image of fault location biggish
Variation, so as to pass through the quality state of the variation accurate judgement aluminium-foil paper of gray value or inner box paper.
Further, step S5 is specifically included:
Step S51, the transmission speed of cigarette package line is obtained.
Step S52, the displacement step Numerical of PLC is set according to transmission speed.
Step S53, judge whether the actual shift value in PLC reaches displacement step Numerical；If so, entering step S54.
Step S54, PLC controls device for eliminating operation.
PLC can accurately control the operation opportunity of device for eliminating according to shift value as a result, so as in cigarette package line
In the state of normal operation, cigarette is assured really rejecting by device for eliminating.
Further, step S2 is specifically included:
Step S21, PLC issues image to photoelectrical coupler and obtains enable signal.
Step S22, photoelectrical coupler obtains enable signal starting image acquisition unit work according to image.
In addition, in the prior art, in order to realize the detection of the presentation quality to inner box paper and aluminium-foil paper, Some Enterprises are adopted
With laser sensor come in diaphragm capsule inner box paper and aluminium-foil paper detect, still, due to the detection mode of laser sensor
It being only capable of detecting by luminous point, detection range is smaller, if there is breakage in the region of inner box paper and aluminium-foil paper other than test point,
Then laser sensor is difficult to, and the cigarette packet stream of inner box paper, aluminium-foil paper breakage is caused to go out.In addition, due to inner box paper and aluminium foil
The color of paper is close, simultaneously because laser sensor only can be carried out the detection that luminous point detects and cannot achieve face, causes to color
Similar aluminium-foil paper and inner box paper accuracy of identification are lower, and detection qualification rate is lower.
And use linear color mark sensor to replace above-mentioned laser sensor there are also Some Enterprises, but since linear colour code passes
Sensor is poor to small failure evaluation ability, can not detect completely to the tiny flaw on inner box paper and aluminium-foil paper,
The cigarette packet stream with tiny flaw is easily led to go out.
It is above-mentioned existing in order to solve the problems, such as, in the present embodiment, before step S2, this method further include: setting figure
As obtaining the period.
Specifically, image acquisition period may include the first duration and more than two second durations, and first when grows up
In the second duration.
Wherein, in the present embodiment, there are three the first duration is set, when continuously set between two the second durations there are three first
Long, image acquisition unit is every as a result, obtains a cigarette packet image by first duration, at the same it is every by one second when
It is long to obtain a cigarette packet image, so that cigarette packet image three times can be obtained in one cycle；And since cigarette package line begins
In operating status eventually, when obtaining cigarette packet image each time, cigarette packet is in different positions, and image acquisition unit is to cigarette packet
Continuous Image Acquisition three times be the image of different angle, it is possible thereby to realize the full side for wrapping aluminium-foil paper and inner box paper to cigarette
Position detection, ensure that cigarette Bao Zhiliang.Meanwhile the defect of aluminium-foil paper and inner box paper is detected by way of obtaining image, it realizes
It is still interior can accurately to determine that defect is located at aluminium-foil paper in combination with the calculating of gray value for the detection that tiny flaw is wrapped to cigarette
Frame paper which thereby enhances the accuracy to the detection of cigarette packet mass defect.
Aluminium-foil paper and inner box paper detection method provided in an embodiment of the present invention, realizes and wraps aluminium-foil paper and inner box paper to cigarette
The detection of defect, while also achieving to there are the rejectings of the cigarette packet of quality problems, improve the quality monitoring effect of cigarette packet.
Further, by the way that the image acquisition period including different durations is arranged, guaranteeing what cigarette package line operated normally
Meanwhile the image for realizing acquisition cigarette packet different angle is realized in combination with the calculating of gray value in cigarette packet all directions
Detection, while can accurately determine that defect is located at aluminium-foil paper or inner box paper, it improves to the accurate of cigarette packet mass defect detection
Degree.
Structure, feature and effect of the invention, the above institute are described in detail based on the embodiments shown in the drawings
Only presently preferred embodiments of the present invention is stated, but the present invention does not limit the scope of implementation as shown in the drawings, it is all according to structure of the invention
Think made change or equivalent example modified to equivalent change, when not going beyond the spirit of the description and the drawings,
It should all be within the scope of the present invention.
