Definitions

  • the invention relates to a measuring device for a filiform test specimen, with a Measuring gap with measuring zones, for measuring properties on a moving test specimen, have the elements of a measuring device and are assigned to a measuring device.
  • Such a measuring device for yarn is known for example from US-A-3,377,852.
  • two electrodes are like this in a gap in a plastic block let in that these together form a measuring capacitor, the measuring field of which Gap crossed.
  • the surface of this gap is made of a thin layer of one Material coated, whose electrical conductivity is lower than that of the electrodes is. This is to ensure that locally occurring static charges caused by touch arise with the moving yarn, spread over this layer and break down.
  • a disadvantage of such a known measuring device is the fact that the dimensioning the conductivity of the thin layer is very difficult because it should be avoided that the layer causes the surface of the electrodes to expand.
  • Measuring gaps in optically operating yarn measuring devices can be Yarn become dirty, which affects the optical measurement. This pollution can counteract a certain self-cleaning by the moving yarn. To pollution To be able to fight effectively through self-cleaning must favorable coordination of the dimensions of the measuring gap are taken into account. That stands contrary to that with narrow measuring gaps with an impermissible wear of the side surfaces or the elements built into it, but this limits the freedom of design generally in the area of such measuring gaps and in yarn measuring devices.
  • the problem to be solved by the invention is now to find the possibilities in devices for measuring filiform test specimens, in particular in the Increase the formation of the measuring gap.
  • This coating preferably covers electrodes, Lenses or windows of optical devices embedded in the side walls of the measuring gap are or parts thereof, as well as gaps or joints between the above Devices or electrodes and the remaining parts of the measuring gap.
  • the coating is done by printing, immersing, steaming, sputtering or spraying the Measuring gap with a material, preferably with the surface of the parts mentioned a chemical bond is formed in the gap and a layer thickness of e.g. 20-30 nm remains applied.
  • the advantages that can be achieved in this way can be seen in particular in the fact that the service life of the measuring gap can be increased.
  • the measuring field ie the space in which the beam path of an optical system or the electrical field of a capacitive system extends, can be reduced. This can be achieved on the one hand by a reduced gap width and on the other hand by a smaller surface area of the electrodes or of the optical elements which adjoin the measuring gap.
  • Another advantage is that the effect of self-cleaning the measuring gap can be better exploited. This can be done by reducing the gap width. Soiling or deposits are removed more safely by the test specimen itself. This effect is stronger the narrower the measuring gap and the more likely the test specimen or protruding parts thereof to touch the side walls.
  • a narrower gap also has the advantage that the influence of the shape, ie the fact that the cross section of the test specimen is not circular but possibly oval, on the measurement of the mass of the test specimen is significantly reduced. This is because in a narrow gap, the yarn no longer appears as a flat body as in a very wide gap for the electrodes or the optical elements.
  • the design of a measuring gap according to the invention also creates better conditions for installing an optical and a capacitive measuring system together in one measuring gap.
  • part 1 of a measuring device with a measuring gap or gap 2 for a test specimen 3, here for example a yarn, is shown schematically and in simplified form.
  • Elements 6 and 7 of measuring devices are fastened to side walls 4 and 5 of the gap 2 or embedded in the side walls 4, 5.
  • These elements 6, 7 can be electrodes of a capacitively operating measuring system or windows, surfaces of prisms, lenses or other components of an optically operating measuring system.
  • Corresponding elements 6 'and 7' can be found in the opposite side wall.
  • the elements 6, 6 'and 7, 7' define on the side walls 4, 5 measuring zones of a measuring device known per se and therefore not shown here for measuring yarn properties such as mass, diameter, hairiness, color, foreign fiber content, etc.
  • a coating 8 here partially covers the side wall 4 with the elements 6 and 7.
  • This coating can only the elements 6, 6 ', 7, 7' or only the base 9 or the entire side wall 4 and 5 and possibly also the base 9 of the gap 2 cover and consists of an abrasion-resistant material that is preferably transparent for optical measuring systems or conductive for capacitive measuring systems.
  • the coating preferably has glass-like properties, ie it is transparent, hard and smooth, so that it presents little resistance to the test piece when touched.
  • the coating can be obtained, for example, by an inorganic material synthesis and form a so-called nanocomposite, with which, for example, a glass-like, scratch-resistant but not brittle or brittle surface can be created.
  • the coating can be applied by immersing part 1 in the material of the coating or by spraying it on.
  • the coating can consist of a so-called sol, which forms a chemical connection with the material on the surface of the measuring gap.
  • sol Such brines are known from sol-gel technology.
  • the coating makes it possible, for example, to reduce the width B of the gap 2 to one Limit value that corresponds to 4 to 10 times the diameter of the test specimen 3 or to provide novel slit forms, such as the figures described below demonstrate.
  • FIG. 2 shows part of a measuring device with a coated measuring gap 10, the can be divided into an inlet part 11 and a measuring part 12. Located for measuring there is a test specimen 13 in the measuring part 12. Another arrangement of an inlet part can also be seen 11 ', which is not arranged as usual in one axis with the measuring part 12, but opens out laterally. Both inlet parts 11 and 11 'shield due to their narrow cross section the measuring part 12 against extraneous light, which is advantageous in optical measuring systems is. This is more the case with the inlet part 11 '.
  • the coating according to the invention also makes it possible to measure the measuring part 12 with three dimensions form curved side surfaces 17, which also act as thread guides, such as this can be seen from FIG. 3.
  • FIG. 3 shows a view of the measuring part 12 starting from a cut surface as shown in FIG 2 is indicated by the arrows A-A.
  • the bottom is in the middle of the gap deeper than at the ends. So it is possible, for example, only the end areas 14, 15 to be provided with a layer 17, 18 according to the invention, so that this function can take a tour of the test material. With that are many other forms conceivable for the measuring part 12.
  • the area 16 may be better Protection with a layer. If the gap 2 is continuous at its base, i.e. without discontinuities such as paragraphs, deposits become continuous removed or taken along by the test material. This is particularly the case with test specimens important, which consist of fibers like yarns.
