    Method and device for measuring the internal pressure of bottles, in particular champagne bottles
    The invention relates to a method and a device for measuring the internal pressure of sealed with a capsule closure bottles, the content of which has a fermentation-related pressure, in particular the internal pressure of champagne bottles, which are closed in particular with crown caps.
    Under capsule closure is here understood a closure of the bottle opening which is like a cover of the bottle opening is placed and held there along an outer circumference of the bottle neck, e.g. at a Außenwulst the opening, wTas causes a liquid and pressure-tight closure of the bottle opening, fall primarily the known bottle caps under the capsule closures of the type considered here, however, the invention can also be applied to other capsule closures, such as plastic caps or screw caps.
    For bottles that are closed with capsule closures such as bottle caps or screw caps, it is necessary in some cases to determine the internal pressure in the bottles.
    For example, in traditional sparkling wine production, the fermentation of the beverage does not take place in tanks but in the original bottle. During this fermentation, the bottles are provisionally closed with bottle caps (similar to the cork of a beer bottle). Finally, the bottle neck is frozen, the temporary cork is ejected and replaced with the final closure with which the bottle is sold.
    The success or failure of this fermentation process, which lasts many months, not least depends on the internal pressure of the bottles, or can be problems with the fermentation (for example, lack of quality of the yeast) by measuring the internal pressure determine. During the fermentation process, the internal pressure of the bottles increases continuously, from initially 0 bar (overpressure to atmosphere) to about 6 bar.
    The pressure test is currently carried out usually by piercing the crown cap and pressure measurement by pressure gauge. The contents of the Hatch are thus in any case for the
    Production is lost because the fermentation process is interrupted or severely disturbed.
    To solve this problem, L PRO SRL (http://iwow.lpro.it, last accessed on July 30, 2010) offers a device which, using laser spectroscopy, provides the Bcdin- «9« 9 Π1831 4k · 4 * * * ft β 8 ft 0 "ft * 0" ft "4 4k ft * ft > Measures the upper part of a closed bottle of wine. In particular, the CO2 or OrGehalt or the pressure in the bottle are measured, the disadvantage is in particular that the associated device is very expensive and sensitive in operation.
    It is therefore an object of the invention to provide a way to measure non-destructively and at low cost the internal pressure of bottles sealed with capsule closures.
    This object is achieved by a method of the type mentioned above for a bottle having a closed with a capsule closure over which the capsule closure forms a closure surface, according to the invention by the following steps: a) projecting a pattern on the closure surface by at least one on the B) detecting the thus generated on the shutter surface image by means of at least one Aufnahrrievorrich turig, and c) determining the internal pressure of the bottle by evaluating the image.
    Thanks to the invention, it is possible to measure the internal pressure in the bottle without contact and without damaging the bottle or the capsule closure. When used in sparkling wine production, it can be determined whether the production is running properly.
    For example, a pattern is used as a pattern, but of course other patterns are also possible. The light beam originates for example from a halogen lamp or a laser diode; the capture of the images takes place, for example, with a digital camera whose results can be evaluated with a PC.
    As the internal pressure of the bottle rises, the capsule closure deforms, in particular by bulging in a direction normal to the closure surface. This results in a pressure-related distortion when using a bar pattern; Conveniently, a value of the distortion of the pattern in the image is therefore determined in step c) and the value of the internal pressure in the bottle is calculated from this distortion value. By evaluating this distortion, the pressure in the bottle can thus be determined (after a previous calibration).
    It is advantageous if the light beam in step a) at an angle of 80 ° to 60 ° to the perpendicular incident on the closure surface. The perpendicular extends orthogonally to the closure surface. ft ft) ft. "" Often ft 8 ft "8" * * * "ft" ft ft * ft ft ft ft * it 9 X > «Ft ft ft« ft 9 ft * * 8 8 pj 1831 j ::: **: »# * *« «-3-
    The detection of the image in step b) takes place from a direction which is different from the direction of incidence of the incident light beam. In other words, the image is acquired by using light emanating from the shutter surface c in a direction different from the incident direction of the incident light beam.
    In a variant of the invention, the acquisition of the image in step b) takes place from a direction which is oriented substantially perpendicular to the closure surface. In a further variant of the invention, the light beam projecting the pattern is incident on the closure surface from a direction which is oriented substantially perpendicular to the closure surface.
    Furthermore, in the method according to the invention in step a) the pattern can be projected onto the closure surface by means of at least one first light beam and at least one second light beam, the direction of incidence of the first light beam on the closure surface being different from the direction of incidence of the second light beam on the closure surface. As a result, a pattern distorted in two directions can be produced on the displacement surface, which also allows good conclusions about the bottle pressure or the deformation of the closure surface.
    The object of the invention is further achieved with an initially mentioned apparatus for measuring the internal pressure of bottles sealed with a capsule closure, wherein a bottle has an opening closed with the capsule closure and the capsule closure forms a closure surface located above the opening. According to the invention, this device comprises at least one illumination device, by means of which at least one light beam can be projected onto the closure surface, at least one receiving device for detecting an image generated on the closure surface, and an evaluation device for evaluating the image,
    This makes it possible to solve the above-mentioned problem, namely non-destructive, quickly and at low cost to determine the internal pressure of a bottle, As evaluation, for example, a PC can be used. With this evaluation device, the determination of the value of the distortion of the light pattern in the acquired image and the calculation of the internal pressure from this, distortion value.

    The optical axis of the receiving device is viewed from the closure surface in a direction perpendicular to the closure surface direction. In a further variant of the invention, the direction of incidence of the light beam generated by the at least one illumination device extends in a direction perpendicular to the closure surface.
    Furthermore, in a variant of the invention, two illumination devices can be provided, which are arranged such that the direction of incidence of the at least one first light beam of the first illumination device is different from the direction of incidence of the at least one second light beam of the second illumination device. This can generate a distorted pattern in two directions, which also allows the determination of the internal pressure of the bottle or the deformation of the closure surface of the capsule closure.
    The invention together with further advantages will be explained in more detail below with reference to an exemplary, non-limiting embodiment, which is illustrated in the accompanying drawings. In these shows schematically:
    1 shows an inventive device for determining the internal pressure of bottles,
    2a and 2b different arrangements of the components of the device according to the invention,
    Fig. 3 is a plan view of a variant of the device according to the invention, and
    4a to 4c show three variants of the resulting pattern when carrying out the method according to the invention at Flascheninnendrücken of 0 bar {Fig. 4a), 3 bar (Fig. 4b) and 5 bar (Fig. 4c).
    1 shows a device 1 according to the invention for measuring the internal pressure of bottles 2 sealed with a capsule closure. The capsule closure sketched in FIG. 1 is a crown cap 3 - as already mentioned above, the method according to the invention is applicable to any type of Capsule closures, for example made of metal or plastic or generally materials that bend sufficiently under the influence of pressure applicable. The crown cap 3 forms a closure surface 3A arranged above the opening of the bottle. -5- PI 1831 «* i 1
    The content of the bottle 2 has a fermentation-related overpressure, which is to be measured without opening the bottle 2. Due to the overpressure in the bottle 2, the closure surface 3A deformed, which is delektiert. For this purpose, in the embodiment described below, a lighting device 4 and a receiving device 5 are used. For evaluation, an evaluation device 10 is provided. This evaluation device 10 may be, for example, a PC or a similar device which has devices necessary for the evaluation of the measurement data.
    In principle, variants with more than one lighting device 4 and with more than one pick-up device 5 and combinations of a plurality of lighting devices 4 and a plurality of pick-up devices 5 are also possible. The recording device 5 is, for example, a digital camera or a similar device that is suitable for taking pictures.
    The illumination device 4 comprises a light source 6, for example a laser diode or a halogen lamp, wherein preferably light sources are used which emit a coherent light which can be well bundled; the light source 6 can accordingly be equipped with an optical element (not shown). For reasons of clarity, it will be assumed below that the light source 6 emits only one light beam 8; but the solution shown is of course also on a light beam or a plurality of emitted from a light source 6 light beam «! applicable. In the radiation direction, a pattern unit 7, for example a grating, is arranged downstream of the light source 6, by means of which a pattern can be imaged by means of the light beam 8
    A grating is a large number of line-like structures (in the simplest case, parallel, even and equidistant) on a flat surface, either as a column in opaque Matena! or intransparent webs are carried out on a transparent plate. Also possible is the design as a reflection grating, where webs and grooves are executed on a reflective surface.
    The Aufnahrnevorrichtung 5 is arranged so that its optical axis 9 extends normal to the closure surface 3A of the crown cap 3. In other words, therefore, the optical axis 9 runs parallel to the perpendicular 13 of the closure surface 3A. The optical axis 9 denotes the axis of symmetry of the optical elements of the recording device 5 (for example a lens system in which the optical axis 9 is then formed by the optical axis of the individual elements). Since axis and perpendicular coincide in Fig. 1, only the reference numeral of the optical axis 9 is used. The illumination device 4 is arranged such that the light beam 8 at a certain angle of incidence 11 on the - 6 -
    Closure surface 3A impinges. This angle of incidence 11 is measured to the perpendicular 13, wherein under "perpendicular". here perpendicular to the closure surface 3A is understood.
    The angle of incidence 11 is obvious between 0 ° and 90 °; however, the value is preferably between 80 ° and 60 °, since particularly good measurements can be achieved in this area.
    Two further embodiments are shown in FIGS. 2a and 2b. For example, the illumination device 4 can be arranged such that the light is incident perpendicular to the closure surface 3A of the bottle 2, while the receiving device 5 is arranged inclined, ie its optical axis 9 becomes perpendicular 13 (the perpendicular 13 coincides here with the light beam 8 of the lighting device 4 and is therefore not again dargesteilt with its own reference numeral) is inclined - see Fig. 2a. In Fig. 2b both lighting device 4 and receiving device 5 are arranged outside the verticals 13. In this case, the optical axis 9 of the receiving device 5 and the light beam 8 of the lighting device 4 can be located in a plane that extends normally onto the sealing surface 3A and is defined by the light beam 8, the optical axis 9 and the perpendiculars 13. This variant is shown in Fig. 2b, the plane is in the plane of the drawing. Of course, other variants are possible in which light beam 8 and perpendicular 13 as well as optical axis 9 and perpendicular 13 lie in their own planes, which occupy an angle to each other. Via the illumination device 4, or its pattern unit 7, a pattern 12 (see, for example, FIG. 4a) is projected onto the closure surface 3A. For example, a grating is used as the pattern unit 7. But other, known in the art samples are possible. In the case described here, the image of the pattern unit 7 on the closure surface 3A is a sequence of adjacent light and dark stripes. If the closure surface 3A is flat, then these stripes are straight, parallel and equidistant. With increasing curvature of the sealing surface 3A (ie when the pressure in the bottle 2 increases), the curvature of the strips occurs and the distance changes, in particular in the central region of the sealing surface.
    FIGS. 4a to 4c show these states, which are also clearly visible to the naked eye: FIG. 4a shows the situation with a bottle internal pressure (overpressure relative to the atmosphere) of 0 bar; the pattern 12 is undistorted. At 3 bar (Fig. 4b) a slight deformation is already visible, which is then clearly visible at 5 bar (Fig. 4c).

    The pattern 12, or, its optical image, are taken up by the recording device 5 and transmitted to an evaluation device 10; in the evaluation device 10, the internal pressure of the bottle is determined from the recorded image. For the BÜdauswer tungs the curvature of the stripe pattern and / or the distance of the strips can be used as a parameter.
    In order to obtain information about the bottle pressure, a calibration of the arrangement with the type of capsule closure used (here, the crown cork 3) is necessary.
    In Fig. 3, a further variant of the invention is shown: Here, two lighting devices 4, 4 'are used, which radiate from different directions on the closure surface 3A. A first light beam 8 thus projects the first part of a pattern 12A onto the closure surface 3A, while a second light beam 8 'from a second illumination device 4' irradiates the second part of the pattern 12A, the direction of incidence of the first light beam 8 being different from the one Incidence direction of the second light beam 8 '.
    The bi-directionally distorted pattern 12A formed on the closure surface 3A, as well as the pattern 12 produced by only one illumination device 4, now allows good conclusions about the cylinder pressure.
