Description
Technical field
This utility model relates to the aberration Real-time and On-line of a kind of polyphaser pad dyeing cloth.
Background technology
Current cloth acetes chinensis method is generally adopted the cloth color lump directly holding standard, carries out artificial judgement, or one camera gathers image, carries out afterwards being divided into left, center, right to carry out acetes chinensis.Although first method can reach the purpose of detection, but human eye has fatigue, it is impossible in process of production always than the aberration facing to cloth.Second method solves the fatigue problem of human eye, but owing to cloth has width, under same light source irradiation, camera hangs over centre, and the color lump of the image that two ends, left and right gather also can change, and difference occurs.
At Authorization Notice No. CN2778851, name has been called disclosed in the Chinese utility model patent of " chromatic aberration auto-detecting regulating system for colouring machine " a kind of chromatic aberration auto-detecting regulating system for colouring machine, it includes image collector and controls processor and output control valve, wherein image collector is the photographic head with vision sensor, its outfan is connected with the control processor input installing dedicated processes software, and the outfan controlling processor is connected to the output control valve of adjustable nip pressure.In this scenario, when adopting single camera, photographic head can move back and forth both sides and the centre that observation is dyed cloth, adopt this structure, photographic head moves back and forth can affect quality of taking pictures, it is difficult to control the aberration of cloth accurately, and in the process that video camera moves, cloth is also moving, and causes the inaccurate of sampled point.When adopting three photographic head, three photographic head are individually fixed in the both sides and centre that diverse location is individually observed to dye cloth, in this adjustment system, by shooting cloth both sides and middle color image, and compare with colour atla, calculating the value of chromatism of cloth, then pass through electric Proportion valve and directly adjust dyeing padding machine both sides and middle pressure, the value of chromatism controlling cloth changes in tolerance interval.Adopting this structure, when cloth width is bigger, the camera collection image mediated is difficult to the color fully represented in the middle part of cloth, is finally difficult to accurately control the aberration of cloth.
In consideration of it, the problems referred to above are furtherd investigate by inventor, this case is then had to produce.
