Definitions
- the present invention relates to a method for monitoring a mixture of at least two components and a rotor blade of a wind turbine, a nacelle cover of a wind turbine and a wind turbine itself. Furthermore, the present invention relates to a device for mixing at least two components.
- rotor blades and nacelle coverings of wind turbines are often made of glass fiber reinforced plastics or carbon fiber reinforced plastics.
- plastics are resins to which curing agents or curing agents must be added in a predetermined mixing ratio, so that these resins cure in the desired time during the production process and have the desired material properties.
- the object of the present invention is therefore to provide a method in which the composition of the mixture can be monitored in a simple manner without damaging the workpiece.
- This object is achieved by a method for monitoring a mixture of two components according to claim 1, by a rotor blade according to claim 9, a nacelle cover according to claim 10, by a device for mixing according to claim 13 and by a method for adjusting a mixing ratio of two or more Components according to claim 18 solved.
- a method for monitoring a mixture of at least two components having different effects is provided. At least one of the components is added a dye. The dye of each component differs from the dye of another component in its color. The mixture of the two components (with the added dyes) is monitored colorimetrically.
- a dye is added to at least two components. Each component has a different effect. Each component is added with a separate dye other than that of the other components, and the mixture of these components is monitored colorimetrically.
- the present invention is based on the finding that the addition of dye with the correct mixing ratio requires the formation of a very specific color in the mixture, which can be monitored very precisely by colorimetric investigations. By colorimetric investigations, even slight differences in the mixing ratio of the color or the dye can be determined. Thus, already prepared mixture can be monitored prior to processing and optionally or optionally even by adding a component later the required mixing result can be produced after another mixing process, so that in the mixture always the correct mixing ratio is present when it is processed further.
- predetermined colors are added to the components. This can achieve a standardization that is very advantageous for an industrial application. This also applies to quantities of paint.
- complementary colors are preferably added to the components.
- the components can also be assigned colors according to a desired mixing result so that the mixture has a predetermined color. This is advantageous if the resulting surfaces should have a certain color.
- Reliable quality control is essential, especially for parts of capital goods, because in such a context, it can quickly go to high sums of money when unexpected and even more unwanted damage occurs.
- safety aspects also play a role that should not be underestimated.
- Effective use of colorimetric monitoring can be realized by a device for mixing at least two components.
- the apparatus comprises storage containers for each component, conveyors with which a predetermined amount of the respective components is taken from each storage container and fed to a mixer, wherein a colorimetric arrangement is provided for the colorimetric monitoring of the mixture produced by the mixer from the components.
- the device comprises a first signal path for influencing the conveyor by the colorimetric arrangement.
- the device according to the invention particularly preferably comprises a switching arrangement for influencing the conveying path of the mixture.
- the switching arrangement can again set the conveying path so that the mixture of the processing processing is supplied.
- the switching arrangement can again set the conveying path so that the mixture of the processing processing is supplied.
- the switching arrangement can be influenced via a second signal path and thus receive signals from the colorimetric arrangement in order to separate out the mixture in accordance with the signals or to feed it to the processing.
- the switching arrangement can also be integrated into the colorimetric arrangement.
- Fig. 1 is a simplified representation of a mixing plant
- Fig. 2 is a simplified representation of the mixing plant with a farbmetri- see arrangement
- Fig. 4 is a simplified representation of an alternative embodiment of
- 5 is a simplified representation of a characteristic curve from which the deviation can be derived from a predetermined desired value.
- the mixing plant shown greatly simplified in FIG. 1 is known in the prior art.
- the reference numerals 10 and 11 show containers with the stock of the respective component. From this component supply in the containers 10, 1 1, the predetermined amounts are fed to a mixer 20 which mixes the components. From the mixer 20, the mixture can then be fed to processing.
- Fig. 2 shows the already described in Fig. 1 mixing plant, supplemented by a colorimetric arrangement 30.
- This colorimetric device 30 monitors continuously or at intervals the color of the mixture of components from the containers 10, 11 and thus (indirectly) the mixing ratio of the storage containers 10, 11 supplied components.
- a mixture of the components eg plastic, resin, filler compound and hardener or curing agent
- dyes may be added to at least one component and colorimetric detection may occur.
- Fig. 3 shows a further embodiment of the present invention z. B. Based on the system of Fig. 2.
- the reservoir 10 is associated with a conveyor 12 and the reservoir 11, a conveyor 13 is associated.
- a first signal path 32 is shown between Conveyors 12, 13 and the colorimetric arrangement 30, a first signal path 32 is shown.
- the colorimetric device 30 recognizes deviations from the predetermined target value of the color of the mixture, it can influence the respective conveyors 12, 13 via this first signal path 32 and thus adjust the desired color of the mixture and thus an optimum mixing ratio again by adjusting the delivery quantity.
- a switching arrangement 34 is provided, which is connected via a second signal path 36 with the colorimetric device 30 in connection. If the colorimetric arrangement 30 recognizes that the color of the mixture is outside the tolerance range, then it can influence the switching arrangement 34 via the second signal path 36 in such a way that this mixture is not supplied to the production 40 but via another conveying path 50, for example. B. collected and disposed of properly and environmentally. As soon as the colorimetric arrangement 30 again recognizes the correct color and thus the correct mixing ratio, it can again influence the switching arrangement 34 via the second signal path 36 in order to feed the mixture back into production 40.
- the second signal path 36 may, as well as the already described above signal path 32 z. B. be a wired, but also a wireless connection, via which signals can be exchanged.
- FIG. 4 shows an arrangement in which the switching arrangement is integrated into the colorimetric arrangement 30.
- the hardener mass fraction is indicated in this figure. That ranges from 0.20 to 0.50.
- hardener is represented with a proportion of 20-50% of the mixing ratio in this figure.
- the ordinate indicates a brightness deviation of the color in%.
- the default setpoint is marked with 0.00, because if there is no brightness deviation, the color is exactly the desired color.
- the mixing ratio therefore corresponds exactly to the specifications.
- This color sets at a hardener mass fraction of about 0.375. Now varies the amount of hardener, then the color brightness changes and from the change in color brightness can be concluded on the hardener mass fraction.
- the characteristic shown here applies to a white-colored resin to a black-colored hardener. If the proportion of hardener increases, the brightness of the mixture decreases and the brightness deviation receives a negative sign. For a hardener mask sen proportion of about 0.42 results in a brightness deviation of - 2%. Correspondingly, with a lower hardener mass fraction of about 0.325, a brightness deviation of + 2% in the color results.
- the mixing ratio can thus be monitored in a simple manner and optionally corrected accordingly.
- the color or dyes added to the components in the containers 10, 11 may also contain luminescent or phosphorescent dyes.
- the finished product such.
- This can also be done in the current production process in order, for. For example, to monitor sample quality at random.
- mobile colorimetric arrangements can be used.
- Complementary colors give a mixed gray tone, in extreme cases black or white.
- On a color circle are complementary colors at the corners of a regular n-corner, where n is the number of components of the colors.
- each of the components used may have a specific hue, so that a colorimetric monitoring of a mixture of the components can be carried out even without the addition of further dyes.
- the components may be plastic, in particular resin, as well as hardeners or hardeners, putty and hardeners or hardeners and components of an adhesive.
- a colorimetric examination by the colorimetric arrangement 30 can be carried out, for example, on the Lambert-Beer's law, the measurement then being limited to a monocromatic measurement.
- the measurement of the colors or the color valences can be carried out by an equality method, a brightness method and / or by a spectral method. In the equality method, the color of the mixture can be compared to a variety of known standard patterns until the two colors are identical.
- an optical detection of the color can be carried out with downstream color filters. Alternatively or additionally, color sensors may be used.
- spectral method a spectral analysis of the colors takes place. This can be done for example by a spectrometer.
- a quality test can be carried out in the manufacture of rotor blades. This quality check is performed biometrically and can thus be implemented without material removal as a nondestructive testing. This quality test can also be carried out after the manufacture of the rotor blades.
- a rotor blade of a wind energy plant can be produced at least partially from a material strain Bergolin 6D970-7038 SPR, shade white and a material hardener Bergolin 7D202-SW-R, shade black.
- the target mass ratio is 100: 60.
- the target color of the mixture can be approx. RAL 7038 agate gray.
- the colorimeter can be a BYK-Gardener "Spectro-guide sphere gloss".
- a permitted fluctuation range of 1.9% hardener mass fraction is present in the mixture.
- the dL described above refers to a hue change, and in particular to the CIELAB brightness difference.
