Summary
A method for setting a fill line on a vessel (6) with the aid of a reference container (1) and a device therefor are described. In order to enable the setting of a fill line on a vessel (6) with a complex shape in a simple manner, without the vessel (6) having to be cleaned afterwards and without having to accept the low accuracy of the fill line position, it is proposed that initially in the vessel (6) or in the reference container (1) a first gas pressure deviating from the ambient pressure is set, which is determined after temperature compensation between gas and solids with the aid of a pressure sensor (2), after which the vessel (6) and the reference container (1) are connected to one another in a flow connection and after pressure equalization and repeated temperature equalization between gas and solids, the second gas pressure that is established is determined with the aid of a pressure sensor (2), after which a comparison value corresponding to the volume of the vessel (6) as the difference between the first and the second based on a reference pressure Gas pressure determined and a mark at that position of the Vessel (6) is attached, which corresponds to a predetermined and the comparison value associated fill level of a predetermined reference volume.
(Fig-1) / 13 (41223) IV
The invention relates to a method for setting a fill line on a vessel with the aid of a reference container, and to an apparatus for carrying out this method.
To gauge vessels, in particular vessels with a complex shape, such as wine glasses, a known volume of liquid is usually introduced into the vessel to be gauged, in order to then mark the level of the liquid with a calibration mark for this known volume of liquid. The disadvantage of this procedure is that the vessel to be gauged is wetted with the liquid and must therefore be cleaned and dried in a complex subsequent work step.
The invention is therefore based on the object of designing the method of the type described in the introduction in such a way that the placement of a fill line on a vessel with a complex shape can be carried out in a simple manner, without the vessel having to be cleaned afterwards and without the accuracy of the fill line position being low must be taken.
The invention solves this problem in that a first gas pressure deviating from the ambient pressure is first produced in the vessel or in the reference container, which is determined with the aid of a pressure sensor after temperature compensation between gas and solids, after which the vessel and the reference container are flow-connected to one another and after that Pressure equalization and repeated temperature equalization between gas and solids, the second gas pressure which arises is determined with the aid of a pressure sensor, after which a comparison value corresponding to the volume of the vessel determines the difference between the first and the second gas pressure based on a reference pressure and a marking that position of the vessel is attached which corresponds to a predetermined filling level and assigned to the comparison value.
The invention is based on the assumption that with a complete seal between the vessel and the reference container and neglecting any air moisture that condenses out, the total number of particles in the enclosed volume is constant at all times. Using the thermal equation of state for ideal gases, the following relationship results between the volume of the vessel V G and that of the reference container V R , the first gas pressure p R1 in the reference container and p G1 in the vessel and the second gas pressure p 2 , the temperatures T of the reference container R and vessel G and the Boltzmann constant k B are considered to be known:
Pr Ar PgAg _ PAr_ P2 ^ g PbTri k B T G1 k B T R2 k B T G2
After the sufficient temperature compensation between gas and solids proposed according to the invention, any heat difference between gas and solids can be neglected, so that the volume of the vessel can be determined particularly simply with sufficient accuracy, by simplifying the above equation as follows:
Vg = V R
P2 - Pri Pgi - P2
If the volume of the reference container is constant, it is sufficient to determine only a comparison value that is independent of the actual reference volume. The position of the fill line can then be determined on the basis of an association between this comparison value and the fill level of a predetermined reference volume in the vessel and a corresponding marking can be made on the vessel. In this context, there are particularly advantageous conditions if a first gas 3/13 pressure that is lower than the ambient pressure is set in the vessel because any pressure losses due to the delayed sealing of the vessel do not affect the measurement result. This is particularly advantageous if an inventive vascular occlusion, described in more detail below, is used.
In order to be able to determine an assignment between the determined comparison values and the assigned fill levels of a predetermined reference volume in a simple manner, it is proposed that a comparison value for several vessels of a similar shape and the fill level of a predetermined reference volume be determined in these vessels and an assignment from them by regression between comparison values and filling levels is determined.
The method can be further simplified if the first and second gas pressures are measured as a relative gas pressure in relation to an ambient pressure and the difference between the two gas pressures is normalized to the second gas pressure. By determining a relative gas pressure, for example with a relative pressure sensor, the following relationship results for the comparison value V, which is independent of whether the first relative gas pressure p retl is determined in the reference container or in the vessel itself:

Tests have shown that due to the simplifications made, temperature differences between the vessel and the reference container of 4 ° C lead to volume distortions of more than 1%. For this reason, it is proposed according to the invention that an air stream with constant temperature flows around the vessel and the reference container, so that the vessel and reference container assume the same solid temperature as quickly and consistently as possible. The temperature of the air flow or of the vessel and reference container need not be known, provided that it can be ensured that the vessel and reference container have the same solid temperature.

The invention also relates to a device for determining the comparison value for the described method, comprising a reference container, a pressure sensor and a pump, characterized in that the reference container is connected via a control valve to a vessel closure provided with a sealing surface. These measures result in a particularly advantageous seal between the vessel to be measured and the vessel closure, because on the one hand the sealing surface enables a seal to be made regardless of the actual position of the vessel in relation to the vessel closure, and on the other hand a seal is also possible if the vessel edge is uneven. For this purpose, the deformability of the sealing surface must be designed in such a way that, on the one hand, unevenness in the edge of the vessel is compensated and, on the other hand, excessive sinking of the vessel into the sealing surface is avoided in order not to falsify the comparison value excessively. In this context, particularly advantageous conditions result when the vessels are placed upside down on the sealing surface of the vessel closure. In this case, the vessel's own weight provides a seal when it is put on. It is self-evident for the person skilled in the art that the term pump can also be understood to mean a compressor for compressible fluids, which can be designed, for example, as a vacuum pump. Particularly advantageous conditions result in combination with the features mentioned above when using a vacuum pump.
If the pressure sensor is designed as an absolute pressure sensor, advantageous measurement conditions result if the ratio of the volumes between the reference container and the vessel between | and 2 lies.
If, on the other hand, the pressure sensor is designed as a relative pressure sensor, it is proposed according to the invention that the ratio of the volumes between the reference container and the vessel lies between -S = and -j = in order to achieve a high measuring accuracy.
The actual volume of the reference container is therefore advantageously to be selected such that it is in each case for the different vessels to be measured
5/13 relationship to the vessel volumes described above, in order to be able to reliably measure different types of vessels.
In order to enable simple control of the device according to the invention, the control valve can be designed as a 2x3 / 2-way valve which optionally connects the vessel, reference container and ambient pressure connection, vessel and pump as well as the reference container and ambient pressure connection, vessel and pump with the reference container closed and optionally the vessel and reference container ,
Tests have shown that particularly precise measurement results are obtained when the reference container is sealed with a surface sealing compound. By means of this measure according to the invention, it can namely be avoided that gas enclosed in sealing grooves slowly flows through the subsequent narrow fits and the gas pressure does not converge or converges relatively late. The same considerations should also be used for threads or other components where there is a risk of gas molecules being trapped and only slowly entering the rest of the vessel or Inflow of reference container volume can be avoided in the device according to the invention.
In order to be able to provide several vessels with a fill line industrially quickly, a system is proposed according to the invention in which the devices described are arranged so that they can be rotated concentrically and with a loading and removal station for the vessels to be measured and a device for marking the vessels at the position of the the fill level corresponding to the reference volume is provided. A blower ensures uniform and rapid temperature control of the vessels and reference containers during the method according to the invention, wherein several vessels are measured simultaneously and filling lines are applied to the vessels on one or more devices for marking the vessels. In a particularly advantageous form, a radial fan can be used here, around which the devices described are arranged so as to be concentrically rotatable.

The subject matter of the invention is shown in the drawing, for example. Show it
Fig. 1 is a greatly simplified block diagram of an apparatus for performing the method according to the invention and
Fig. 2 shows a simplified section through a system according to the invention on a smaller scale.
An apparatus for carrying out the method according to the invention comprises a reference container 1, a pressure sensor 2 and a pump 3, the reference container 1 being connected to a vessel closure 5 for a vessel 6 via a control valve 4. In order to seal the vessel closure 5 with respect to the vessel 6, a sealing surface 7, for example made of a flange sealing mat, is provided.
The control valve 4 and the pump 3 are operated via a control unit 8, which evaluates the measurement results of the pressure sensor 2. In order to enable a simple sequence control, the control valve 4 can be designed as a 2x3 / 2-way valve, the optional vessel 6, reference container 1 and ambient pressure connection 9, vessel 6 and pump 3 as well as reference container 1 and ambient pressure connection 9, vessel 6 and pump 3 when the reference container is closed 1 and optionally connects vessel 6 and reference container 1 to one another, as will be explained in more detail below:
According to the method according to the invention, a vessel 6, for example a wine glass, is first placed on the sealing surface 7 of the vessel closure 5. The control valve 4 connects both the vessel 6 and the reference container 1 to an ambient pressure connection 9. The control valve 4 is then actuated to connect the vessel 6 to the pump 3 and to close the reference container 1. During this valve state, the vessel 6 is evacuated, for example, as a result of which the vessel 6 presses against the sealing surface 7 and the sealing effect increases as the gas pressure in the vessel 6 decreases. During this process, both the vessel 6 and the reference container 1 are surrounded by an air stream at a constant temperature, around the same temperature
Ensure 7/13 of vessel 6 and reference container 1. After temperature compensation between vessel 6 and reference container 1 on one side and between gas and solids on the other side, the first gas pressure in vessel 6 is determined using pressure sensor 2 and passed on to control unit 8. The control unit 8 then switches the control valve 4 in such a way that the vessel 6 and the container 1 are fluidly connected to one another. After pressure equalization and temperature equalization between vessel 6 and reference container 1 and after temperature equalization between gases and solids, the second gas pressure is determined with the aid of pressure sensor 2 and also passed on to control unit 8. The control unit 8 then calculates a comparison value as the difference between the first and the second gas pressure related to a reference pressure and calls up a fill level of a reference volume associated with this comparison value from a reference memory. If necessary, it is also possible to interpolate between stored base values. Based on the determined fill level of a reference volume, the control unit 8 controls a device 10 for marking the vessel 6, which then applies a fill line to the vessel 6 at the position of the fill level corresponding to the reference volume. The vessel 6 and the reference container 1 are then reconnected to the ambient pressure connection 9 and the vessel 6 can be removed from the vessel closure 5 after the pressure has been equalized.
The embodiment of a system according to the invention shown in FIG. 2 comprises several devices 11 according to the invention, which are arranged concentrically rotatable about a radial fan 12 on a turntable 13. The vessels 6 are placed on a sealing and removal station, not shown, on the sealing surfaces 7 of the vessel closures 5 and, when rotating around the radial fan 12, go through the method described above, at the end of which a device 10 for marking the vessels at the position of the a fill stroke is applied to the vessels 6 according to the fill level corresponding to the reference volume.
