Electro-optical yarn sensor equipment 3 comprises lighting unit and image-generating unit.Lighting unit comprises at least one light source 31 and illumination optics 32.For example light emitting diode (LED) can use as light source 31.Light source 31 be transmitted in visible light, infrared and or ultraviolet spectral range in the photoelectricity ray, it will be summarised as term " light " in this manual in order to simplify.Illumination optics 32 calibration is transmitted in light on the yarn 9 by light source 31.Image-generating unit comprises image optics device 33 and electro-optical imaging sensors 34.Imageing sensor 34 is preferably the two-dimensional image sensor 34 with a plurality of image components (pixel) of arranging with matrix-style.This imageing sensor 34 is commercially obtainable with the integrated electro component form in various technology, and it for example is known that digital camera and is widely used.Alternatively, also be known and comprise that the one-dimensional array sensor that is arranged in perpendicular to a plurality of pixels on the straight line of the longitudinal axis setting of yarn can use as imageing sensor 34.Image optics device 33 is imaged on yarn line segment on the imageing sensor 34, and it will be discussed in more detail with reference to figure 3 time.According to the present invention, imageing sensor 34 is integrated in the opertaing device 2.Like this expression, imageing sensor 34 attaches to an identical same printed circuit board (PCB) 22 with processor 21.As a result, when recording the image of yarn 9, the evaluation of the signal of imageing sensor 34 occurs at same printed circuit board (PCB) 22 (" onboard ").
Fig. 3 represents electro-optical yarn sensor equipment 3 in more detail and still in simplifying view.Light source 31 is via one section of illumination optics 32 illumination yarns 9.Preferably, used kohler's illumination, it is known from the micro field of copying, and will it not explained in more detail at this.Suitable image optics device 33 is imaged on the section of yarn 9 on the imageing sensor 34.In order to simplify illumination, illumination optics 32 and image optics device 33 are shown in Figure 3 for unzoned lens.Be appreciated that and use more complicated optical system that it also comprises other optical elements except lens, for example aperture or filter disc.Preferably, in propagating, light produces preferably imaging, that is, when not inserting yarn 9, light source 31 illuminated picture image-position sensors 34, and when yarn 9 has inserted, at least a portion that it shuts out the light.In this illustrated, yarn 9 illustrated the yarn main body 91 that is shown as circular section, extended radially out radially the outside from each single fiber of this circular section (" filoplume ") 92.
When the longitudinal axis 90 of yarn 9 do not intersect with the optical axis 30 of electro-optical yarn sensor equipment 3, but for example with the distance of a=2 to 6mm and when preferably separating with about a=4mm and described between centers, the linear measure longimetry of application filoplume is favourable.Described axialy offset a is based on such hypothesis, and yarn 9 is rotational symmetric, and the filoplume length value of therefore preparing to measure equates along the yarn circumference (at least when when concrete specific length of yarn execution averages).If should symmetry hypothesis applicable, so only need to consider half space 93 that limited by length of yarn axle 90, and can ignore with half space 94 of its complementation.In half space 93 of considering, can in better mode, namely check described filoplume with higher resolution.
Fig. 4 exemplarily represents each image when by two-dimensional image sensor 34 record.As the result of aforementioned axial biasing a, yarn main body 91 is not arranged in the middle part and is arranged on the edge of image.As a result, reach filoplume 92 in being seen half space 93 by in more complete mode and with higher resolution projection.Because the symmetry of mentioning hypothesis, other filoplumes that reach in other half spaces 94 of loseing interest in recede into the background.Can obtain more accurate and reliable measurement result by estimating a plurality of images by the statistical method estimation.The measurement result that obtains from single image can be superposeed mutually in any other mode, average or combination.
In one dimension imageing sensor 34 situations, as shown in Figure 4, a plurality of image lines of following continuously can be at first with the synthetic two dimensional image of the first set of variables.To estimate two dimensional image after this.In the second variable, process each one dimension image in the mode identical with the above-mentioned mode of having described for two dimensional image.Obtain net result by combination from the measurement result that single image obtains.
A problem in the filoplume linear measure longimetry is the limited depth of focus of image optics device 33.It causes becoming mildewed plumage 92 along the direction of optical axis 30 from end out of focus ground projection that yarn main body 91 is stretched out and will be so that the result of measured value distortion.In order to alleviate this problem, recommendation double focusing optical device is as image optics device 33.A possible embodiment is illustrated among Fig. 5.Plane-parallel plate 35 inserts in the band imaging beam path by this way, and it only affects the part 37 that light arrives the light of imageing sensor 34, and another part 36 is crossed this parallel-plate 35 by imageing sensor 34.The result of the parallel displacement that is caused by plane-parallel plate 35 as light beam 37, the objective plane 39 of light 37 that is used for being subject to the plane-parallel plate impact is more farther from imageing sensor 34 than the objective plane 38 that is used for unaffected light 36.Therefore will in two planes 38,39, see imageing sensor 34 with sharp-pointed sharpening limiting mode.Plane-parallel plate 35 can be circular, annular or any other shape.Alternatively, it can be replaced by and optical element that can realize double focusing or multi-focus imaging parallel as on-plane surface.
In further embodiment (not shown), can be designed to picture optical device 33 with nonlinear way.On the one hand can realize the higher depth of focus by " cutting is made " " customized " device for non-linear optical, it is so that subplan, and for example the plane-parallel plate 35 of Fig. 5 is unnecessary.On the other hand, device for non-linear optical can design by this way, and it has the local non-constant imaging size that outwards drops to the outside.As a result, can detect very long filoplume 92 (for example having the length that height reaches 16mm) and detect short filoplume 92 with constant high resolution with low resolution simultaneously.The distortion of this device for non-linear optical is known and can compensates with account form in the evaluation to filoplume length.
As shown in Figure 1, electro-optical yarn sensor equipment 3 avoids being subject to mechanical effect, pollution and light from the outside by sender unit cap 16 protection that is fixed to housing 11.Fig. 6 exemplary table is shown in the opticpath in the zone of measurement clearance 81, and yarn 9 passes through measurement clearance in a longitudinal direction.Each comprises transparent wall element 82,83 parts as sender unit cap 16 to measurement clearance 81 at the wall on the emitter side and the wall on receiver- side.Wall elements 82,83 allows to measure light and passes, but light source 31 and imageing sensor 34 are blocked out with measurement clearance 81.According to the present invention, wall elements 82,83 is designed to flat cover, its not relative to each other positioned parallel in order to stop the Multi reflection do not expect and produce phantom and interference effect.Wall elements 82,83 preferably relative to each other tilts by this way, observes such as the longitudinal direction along yarn, and measurement clearance 81 has from housing 11 outside tapered sections.
Be appreciated that and the invention is not restricted to embodiment as discussed above.Those skilled in the art can derive other distortion by knowledge of the present invention, and it also belongs to the theme of the present invention as limiting in independent claims.
