Description
Technical field
The present invention relates to a kind of vision detection system, be particularly related to a kind of weaving loom fabric defects vision detection system, it mainly is suitable for the quality defects defects detection that Weaving device has the fabric faces such as tricot machine, air-jet loom, loom, large circle machine, arrow shaft loom, belongs to the real-time online checkout equipment.
Background technology
In Modern Textile Industry, the automatic detection that replaces human eye to carry out fabric defects with advanced person's detection technique can improve detection efficiency, reduce the labour, reduce labour intensity and further improve the quality of fabric.But in China, fabric detects most of or is finished by the artificial vision, and in testing process, there is deviation in human eye vision, and fidelity factor is lower and testing result is unstable, and these are all inharmonious with large-scale industrial production.In weaving is produced, if there are lines to break, if not in time discovery of workman will be produced some substandard products cloth, cause the waste of material and the energy.If after finding flaw, stop immediately behind the installing fabric flaw vision detection system producing, can reduce the waste of material.
The detection means of this field application mainly detects with Manual Visual Inspection and the campaign-styled equipment of mechanical reciprocating at present.The machine movement formula detects the main motor that uses, and a slide rail is fixed a sensor made from photoresistance at slide rail, in the fabric face detection that moves reciprocatingly.The groundwork principle is the quality that the difference of utilizing photoresistance to pick up the cloth cover intensity of light reflection is judged cloth cover, and the fabric face intensity of light reflection is more or less the same when fabric is normal, but when producing flaw photosensitive resistance detection to reflection strength have slight variation.If cloth cover has irregular pattern or netted cloth cover, the cloth cover that transmittance is very high, the existing technology of very thick cloth cover just can't be picked up, this equipment is only applicable to that those are very thin and the fabric of certain density arranged, because the signal pickup assembly that it adopts is not Real-time Collection, so the cloth cover texture of complexity is not had whole judgement, it can only be judged certain point, the signal sensitivity dynamic range is also very little, so it can't pick up the subtle change of fabric face.This cover system is owing to the existence of motor in addition, and power consumption is higher also to be inevitable.Because the volume of weaving loom is very large, weaves the cloth breadth very wide, general breadth width is that 3-7 rice is wide, and braiding speed is also than comparatively fast.So there are the following problems for such scheme:
(1) so flaw can not be in time found in non real-time detection, this is because the surface area of fabric is very large, causes flaw long excessive;
(2) known detection mode belongs to the detection of mechanical motion formula, so poor reliability;
(3) the suitable fabrics kind is few;
(4) power consumption is large;
(5) failure rate is high;
(6) be that collection signal is carried out in photoresistance owing to what adopt, so insufficient sensitivity is high;
(7) owing to there is the mechanical part of large amount of complex to exist, so cause the higher accuracy requirement to machine parts of production cost also very high, be difficult for batch production;
(8) labour cost can be very high, and every weaving loom is wanted a worker management;
(9) the flaw recall rate is low, because Manual Visual Inspection works long hours, visual fatigue can occur, finally causes deterioration in quality.
So the textile exports amount of China descends year by year at present, its main cause is exactly that also there is a big difference because our textile is on quality with abroad, and labour cost is too high in addition also is the Main Bottleneck that export volume descends.Obviously above-mentioned traditional detection means is worthless, will be left behind by time, and what replace must be those high-tech detecting instrument equipment.
Summary of the invention
The present invention proposes a kind of weaving loom fabric defects vision detection system, solved that Defect Detection is untimely in the prior art, recall rate is low, the high in cost of production defective, the present invention is easy to use, the flaw recall rate is high, and can in real time the Defect Detection on the fabric out and in time be processed, reduce workman's labour intensity and labour cost, improved the product quality of fabric.
