Tow stain information collecting device
Technical field
The present invention relates to a kind of tow stain information collecting device, be specifically related to a kind of device that utilizes camera to carry out the information acquisition of tow stain.
Background technology
Improving constantly of Along with people's living standard; People are high more to the quality requirements of daily necessities, and people can't permit flaw in the eyes, because those flaws not only can reduce the quality of production; Also can have influence on commercial production efficient; Especially dust on the tow or lurid machine oil stain, these stains not only influence the quality of tow, simultaneously health are also exerted an influence.Those stains are under the situation of high-speed motion, and iff goes to distinguish by human eye, can't accurately judge the position and the size of stain, also are unfavorable for that the stain of tow in enormous quantities detects simultaneously.
Summary of the invention
To the objective of the invention is the shortcoming that accurately to distinguish stain on the tow in order solving in the prior art, a kind of device that can carry out exact acquisition to tow stain information to be provided.
In order to achieve the above object, the invention provides a kind of tow stain information collecting device, place, comprise support, metal fixed head, camera, light source, backing plate and camera bellows by roller, from tow travelling belt one side that pinch roller and main pinch roller are formed; Said support vertically is provided with; Said metal fixed head is fixed on the support; Said camera and light source are fixed on the metal fixed head, and are positioned at the tow top; Said shim is on support, and the parallel tow below of being located at; The tow of said support, metal fixed head, camera, light source, backing plate and backing plate top all is located in the camera bellows.
Further improvement of the present invention is: camera perspective is vertical with tow; Above-mentioned light source is two, is located at the camera both sides respectively, and the incident ray intersection point of two light sources and the vertical photograph of camera are taken the photograph and overlapped.
Tow stain information collecting device also comprises fan and power-supply controller of electric, and fan is located in the camera bellows, and power-supply controller of electric connects camera, light source and the fan in the camera bellows respectively.
Wherein, the transfer rate of tow travelling belt is 10 meter per seconds, and is 15-30 ° of angle with horizontal direction.
Tow stain information collecting device links to each other with data processor through data line, and data line one end links to each other with camera in the camera bellows, and the other end links to each other with camera bellows data processor outward.
The present invention has the following advantages: through camera the tow stain of high-speed motion is taken, the identification of naked eyes is more accurate relatively; The light source incident ray of camera both sides and camera are vertical to be overlapped according to taking the photograph, and increases brightness on the tow, and the stain image that camera is photographed is more obvious; Simultaneously backing plate is installed in the tow below, can effectively avoid light source irradiation inhomogeneous or overlapping and shade that cause reduces the interference to images acquired; The tow of camera, backing plate and shooting all is arranged in the camera bellows, can effectively reduce external influence, improves the accuracy of stain information acquisition; Fan is set in the camera bellows, has good heat dispersion.

Embodiment
Below in conjunction with accompanying drawing tow stain information collecting device of the present invention is elaborated.
Tow stain information collecting device of the present invention carries out the stain information acquisition to the tow in the high-speed motion.This device places by roller 2, from tow travelling belt one side that pinch roller 3 and main pinch roller 4 are formed, and comprises support 6, metal fixed head 7, camera 8, light source 9, backing plate 10, camera bellows 11, fan 12 and power-supply controller of electric 13.Tow travelling belt and workbench 16 (being horizontal direction) are 15 ° of angles, and the transfer rate of tow 1 is controlled to be 10 meter per seconds.Support 6 connects a transverse slat by two montants and forms, and transverse slat places on the workbench 16, and the distance between two montants is 30cm.Metal fixed head 7 long 50cm, wide 40cm, Corner Strapped is on two montants of support 6.Camera 8 is fixed on the metal fixed head 7 with light source 9, and is positioned at tow 1 top, and vertical range is 20cm.The visual angle of camera 8 is vertical with tow 1, and light source 9 is two strong brightness light sources, lays respectively at the camera both sides, and the intersection point of the incident ray of two light sources just in time overlaps according to taking the photograph with camera 8 is vertical.Backing plate 10 is fixed on two montants of support 6, and parallel tow 1 below of being located at.The tow of support 6, metal fixed head 7, camera 8, light source 9, backing plate 10 and shooting, collecting section all is located in the camera bellows 11.Simultaneously fan 12 is located in the camera bellows 11, is fixed on two montants upper ends of support 6, effectively dispels the heat, and drops to the consumption of element minimum.Power-supply controller of electric 13 is located at outside the camera bellows 11, links to each other with fan 12, light source 9, camera 8, supplies power.
Roller 2, engaged wheel 3 and driving wheel 4 are by the transmission of gear train (not shown), and tow 1 gets into through roller 2, through getting into the tow case 5 from pinch roller 3 and main pinch roller 4, clockwise rotate from pinch roller 3, and main pinch roller 4 rotates counterclockwise; Tow 1 fixes a point to take through the camera on it 8 in transmission course, gathers tow stain image.Because whole shooting process is arranged in camera bellows 11; Can effectively completely cut off extraneous interference; The backing plate 10 of two light sources 9 below focusing on the shooting section tow and shooting section tow can better be avoided the inhomogeneous and overlapping shade that causes of light source irradiation, reduces the interference to the collection picture.The image that camera 8 is gathered sends data processor 15 to through data line 14, and data processor 15 deal with data filter out the image with stain, and the staff judges the position of stain on the tow according to the time of image taking, handles to make waste silk.
