Description

DEVICE AND METHOD FOR MEASUREMENT-FREE FILLING OF ONE

The invention relates to a filling apparatus which operates without measuring means and to a method for filling a container without fluid into the medium without using measuring means.

Filling devices and methods for filling containers are known in various embodiments. In the case of liquids such as wine or even chemicals, it is often impossible to prevent the liquid from being exposed to the ambient air and resulting in undesirable gas binding, gas exchange or gas introduction, which may result in a change in the quality of the liquid. Known in the prior art are methods such as that disclosed in DE 10 2011 1005 60 B3, in which a device for the effective gas-contactless filling of a container with a liquid intended for consumption is described for carrying out the method. The implementation of the method there provides that at least one balloon-like, expandable body is first introduced into the container, which is arranged on a pipe and this tube wrapped. By this balloon-like body is allowed to expand after insertion into the container, it fills the interior of the container completely and displaces ambient air from the container. Then liquid is allowed to flow into the container and at the same time displaces the expansion medium through the tube from the balloon-like body. After the container has been completely filled, the balloon-like body is removed again from the container and made available for the next filling operation.

In order to always be able to fill the same filling quantity into the containers, in processes such as the one described above, the liquid is filled by means of a control instrument, usually a magnetic-inductive flowmeter (MID), for filling the container with a desired filling volume or nominal volume. Sensor), sensor-controlled pre-dosed or filled by means of a piston system in the respective container.

For reasons of production, containers, such as bottles, can be provided for receiving the same volume, but may have floors or walls of different thicknesses, so that the actual volume of the container varies slightly in the case of glass bottles

CONFIRMATION COPY usual capacity for wine, etc. in the range of up to 10 ml, which causes the MID always correctly metered volume leads to different filling heights, which is visually very clearly in the area of the bottle neck - and so affects the behavior of the buyer.

Based on this prior art, it is an object of this invention to provide a method for filling containers, in which a constant filling level can be achieved even with different container shapes. This object is achieved by a method having the features of claim 1.

The further object of providing a simple and reliable filling device for carrying out this method is achieved by the filling device having the features of independent claim 7.

Preferred embodiments of the method and the filling device are set forth in the subclaims.

The inventive method for measuring medium-free filling of a container with a fluid is carried out according to a first embodiment with a filling device comprising an attachment with a predetermined volume VA. The article has a valve cap which has a gas valve and a liquid valve with valve seat in a housing. The valve seat surrounds, forming an annular gap, a displacement element which can be displaced longitudinally relative to the housing.

The method according to the invention comprises the following steps:

a) sealingly placing the attachment with its underside on a container, while introducing the displacement element in the container. b) opening the liquid valve and allowing filling fluid to flow into a nominal volume VNn of the container formed by the volume VA of the cap and a volume VB of the container until the nominal volume V enn is flooded with filling fluid, then closing the fluid valve. In general, even the volume VFv of the liquid valve is flooded, but this volume is expelled when closing the liquid valve. is therefore not to be considered in the well-known valve handling, as it does not lag. If this volume remains in the attachment due to the appropriate valve design and handling and is not pushed back in the direction of the fluid source when closing, it can also flow in and must be taken into account.

Then, in step c), the extraction of the displacement element from the container, and running allow the volume VVA (and only in special cases, the volume VFV) in the container, the volume VVA or in special cases, the volumes VVA and VFV is just as large are like the volume of a portion of the displacing element in the flooded section, so that the same containers are filled with equally high levels.

After this, the container can be disconnected from the attachment and closed. The procedure can be repeated from the beginning.

The method is therefore "measurement-free", which means in the sense of the invention that a desired amount of fluid is provided only by formation of defined volumes of individual components which together form the nominal volume VNenn, as will be explained further below V _Nen n to be filled in the respective container volume of a predetermined nominal height to be achieved.

"Equal containers" here means vessels that are identical except for production-related deviations of the wall and floor thickness.

A development of the invention may comprise the step a '), after which, after insertion of the displacement element, a balloon-like body, which is slipped over a pipe, by supplying an expansion medium, can be expanded until the container to be filled and in particular the nominal volume VNenn is lined.

"Until the container to be filled is lined" here means that the balloon-like body lines said volumes such that a gap between the inner wall and the surface of the balloon-like body remains, which the fluid flow, respectively, the air displacement along the balloon-like body during expansion before filling, even if it builds up on the wall during expansion, thus avoiding gas pockets in the container, but it is not always necessary that a gap between the balloon and container wall remains.

"Fluids" may be liquids such as beverages or chemicals, and "expansion media" may be gases such as air or inert gases or liquids capable of filling the respective balloon-like body.

Further, in a further step b '), after opening the liquid valve, the balloon-like body may be collapsed, by releasing a vacuum applied to the container, which has sucked the balloon against the inner wall, or by allowing the expansion medium to escape from the balloon-like body again becomes, happens; while continuing to let the fluid flow into the container.

The two additional steps allow the process to allow sensitive fluids to be filled, as the air in the reservoir can be squeezed out by inflating the balloon-like body or balloon, leaving little room for air to come into contact with the fluid. Furthermore, other fluids, such as residual water from a rinsing process or the like, can be removed from the container by the balloon before the actual filling fluid is introduced. In particular, the patent applications DE 10 2014 008 234 and DE 10 2012 021 775 A1 are expressly incorporated and refer to their content, wherein filling devices are disclosed, which are filled or emptied with the balloon-rod principle.

In step b), the liquid valve closes after the fluid that is filled, the container and also the valve has completely filled (passive control). Alternatively, the fluid may trigger a valve mechanism when active control is provided. For this purpose, the liquid valve may be a pressure valve. In order to prevent too much fluid from being filled in or too high a pressure within the filling device, it can further be provided that in a step b ") the liquid valve is closed when a predetermined pressure is reached in the filling fluid circuit Also, for this purpose, a passive component such as a pressure relief valve may be connected to a liquid supply line container-specific varies or is adjusted. A nominal height to be achieved in each container corresponds to a nominal volume V _Nen n, which is specific to each container shape.

The nominal volume is essentially determined by the nominal height hNenn, to where the container is to be filled. Important for compliance with the nominal height hNew at each filling is now that the displacement element protrudes a certain length hßaiion in the container and just displaced thereby formed volume accordingly. In order to achieve the nominal volume, it is necessary to replenish the volume displaced by the displacement element in the container. This can be achieved according to the invention by reflecting this volume in the components of the article. In short: The displacement volume of the displacement element in the container corresponds to the residual volumes in the attachment minus the displacement element.

The void volumes are composed of different volumes of the components of the filling device:

Thus enters into the nominal volume to be reached VNenn a volume V _{B of} the container. Furthermore, a volume VA of the attachment can be formed in the attachment through a through-hole and various recesses. Also within the liquid valve, a volume VFV can be formed. The displacement element together with the balloon-like body in its unexpanded form occupies a volume of fluid in the container and the remaining components of the filling system, this volume not being included in the aforementioned volumes, but being drawn off as the displacement volume. If the balloon-like body is thick-walled, a correspondingly larger displacement volume results than with a thin-walled material. The result is the formula:

VNenn = VB + VA - Vßallon, Bzw. in the special case described above, when the liquid is not forced back into the fluid source when the valve is closed by a corresponding design of the valve attachment:

VNenn = V _B + VA + VFV - Vβallon

The total volume of the various add-on components excluding the container volume In this case, lumen corresponds to the volume within the filling device displaced by the tube including the balloon-like body as a whole. In other words, the volume displaced by the displacer including the balloon-like body within the receptacle is the same size as the residual volumes formed by the attachment components without the displacer. When pulling out the displacement element, and thus possibly also the balloon-like body, just this residual volume can slip and fill the container.

The stated volumes within the attachment can also be adapted to the specific container by providing compensation volumes in the valve attachment or in other suitable regions of the filling device. Thus, several or even only a volume compensation element in the filling or liquid valve can be mounted below or above this. The nominal volume can thus be matched to any container shape, which makes it possible to fill different container shapes same capacity with the required nominal volume so that always the same filling level is achieved in the different containers.

To use a further volume compensation element container-specific and easy in the process, it can be provided that the article further comprises a volume compensator which is fluidically coupled to the valve cap, wherein the volume compensator in step a) with its underside placed tightly on the empty or full container can be. In general, the volume compensator can also be arranged above the valve cap. The volume compensator above the filling valve is basically the same design as below the filling valve. It would then be positioned as an "intermediate" between the balloon retainer and the fill valve, in which case the balloon retainer will still be the topmost point, concentrically holding the balloon within the volume compensator and fill valve, thus still displacing all of the air from the volume compensator and the filling principle is obtained as in the variant in which the volume compensator sits directly on the vessel.

The interior of the volume compensator forms a predetermined volume WK, which may be fixed in one embodiment. As a result, the volume of the attachment VA can be composed of a volume WA formed by the valve attachment and the volume WK of the volume compensator: In a further embodiment, the volume of the volume compensator can be adjusted by suitable volume change devices for different container sizes and thus variable. "Variable" here means that not only a fixed, invariable volume is formed by the different cavities in the filling device, and thus For example, the volume can be matched to the containers to be filled or to the depth of immersion of the displacement element, for which the volume compensator can also be multi-part, in particular two-part, and different depending on the choice of the assembled elements Form volume sizes.

The active volume of the respective compensating element can also be variable if the device is to be retrofitted for the filling of different containers. A variable displacement can be achieved, for example, by means of sliders, a guide roller or variable / different wall thickness, the contour of a stopper and a matched shape of the balloon-like body. This means that CC> 2-containing liquids can also be filled in without the so-called "gushing" (foaming due to sudden pressure relief) A constant fill level, ie a specific fill volume per container, can thus be achieved for different containers by providing certain The volume to be filled in can be adjusted by the volume compensator depending on the container to be filled in. Also, additional equalizing volumes can be provided within the valve cap, which are formed, for example, by recesses or grooves in a through bore of the valve cap can.

In a further embodiment, the invention provides that in step a ') the expanding balloon-like body has a longitudinal web along its circumference. This extends in the longitudinal direction of the balloon-like body, so that in the expanded state of the balloon-like body between the surface of the balloon-like body and an inner surface of the attachment, a gap is formed along the balloon length. Also, the balloon-like body with respect to its number of webs could have significantly more webs than the at least necessary to fulfill a web to let see less liquid in the Fla- see or to increase the displacement of air in the container or a liquid. Also, grooves or other devices may be used for this purpose. be seen. For the possible embodiments of this body, reference is made to DE 10 2014 008 234.

The contribution of the balloon-like body to the volume Vsaiion is essentially given by its wall thickness. Depending on which type of container is to be filled or how large the volume to be filled, the balloon-like body may have a wall thickness of several microns to several millimeters.

An embodiment of a measuring device-less filling device according to the invention for carrying out the aforementioned method for achieving a same level in the same containers has the following components:

The filling device has an attachment with a predetermined volume VA, which sits tightly on the container and comprises a valve cap. The valve cap itself has in a housing on a gas valve and a liquid valve, each having a valve seat. The valve seats surround a displacement element to form an annular gap, wherein the displacement element can be moved longitudinally relative to the housing axially. With the liquid valve, a fluid supply line is further connected, which may be filled with a fluid to be filled. According to the invention, the filling device in the fluid supply line has no volume measuring device and has no level height measuring device.

The abovementioned filling device is thus "without measuring means", which means in the sense of the invention that fluid can be metered only by providing defined volumes of individual components which, taken together, form the nominal volume VNenn, as already explained above, whereby this nominal volume corresponds to VNom to be filled in the respective container volume of a predetermined nominal height to be reached.

According to the invention, it can further be provided that the attachment has a volume compensator with a predetermined volume VVK, which is fluidically coupled to the valve attachment and can be placed on the container in a fluid-tight manner. The volume compensator can serve as a volume compensation element whose internal volume can be fixed or variable. The displacement element may have different suitable embodiments. In an embodiment according to the invention the device for filling a With a liquid is provided that the displacement element may be a tube with a balloon-like body, wherein the balloon-like body can envelop the tube partially or completely. However, the principle according to the invention basically also works without a balloon, so that, for example, it can also be provided that the displacement element is a simple tube. Thus, the liquid does not have to be withdrawn directly from the container or filled into it by means of a valve, but can be handled in an improved manner via the following inventive design: For this purpose, the tube can be arranged on a holding section of the valve attachment and positioned concentrically through a passage opening of the holding section and continue through the passages of the valve seats. The tube may protrude in a use arrangement close to a bottom of a given container, so that neither the bottom nor the balloon-like body are damaged. The balloon-like body is pulled with its closed end over the free end of the tube and extends through the valve cap into the holding portion in which it is fixed.

In one embodiment, the balloon-like body in the passage opening of the holding portion by means of a clamping body, which is preferably supported via a spring against the upper portion of the Haiteabschnitts, fluid-tight manner. By this arrangement, the balloon-like body sits securely on the tube even when pressure acts on the balloon and allows it to expand or unfold. The tube may extend upwardly through a bore and be inextricably received in a mounting stud, which in turn may be releasably coupled to a fluid source, such as a gas source. A further embodiment of the invention may provide that the gas valve and the liquid valve comprise, in addition to the valve seat, an annular closure part, the valve seat and closure part being movable relative to each other and being arranged coaxially with one another. So that the valve attachment or the volume compensator can be placed in a fluid-tight manner on the container, a seal can be provided on the container-side opening of the respective component which is to denser.

Other embodiments as well as some of the advantages associated with these and other embodiments will become apparent and better understood by the following detailed description with reference to the accompanying drawings. The figures are merely a schematic representation of embodiments of the invention. Showing:

Fig. 1 is a longitudinal sectional view of a filling device according to the invention, and

2 is a longitudinal sectional view of an alternative filling device with a volume compensator.

The filling device 10 according to the invention, which is shown in Fig. 1, is used here for filling a bottle 1, but in principle can be used for any other container.

In this case, the filling device 10 has an attachment which comprises a valve attachment 2. Through the valve cap 2, a tube 3 is passed here as a displacement element, over which a balloon 4 is slipped. The balloon 4 is designed such that it remains in an expanded state between its surface and an inner wall of the valve tower 2 a gap. In Fig. 1, the balloon 4 is not shown expanded.

In this case, the tube 3 protrudes from the bottom of the valve cap 2. The valve cap 2 is designed so that it sits with its underside close to the bottle 1 (see Fig. 1). In Fig. 2 it is shown that between the bottle 1 and the valve cap 2 a volumenkom- pensator 2 'is placed tightly on the bottle 1. This is mainly used to compensate for different volumes of different types of containers. FIGS. 1 and 2 each show a method step in which the container 1 has just been connected in a fluid-tight manner to the valve attachment 2, and the balloon 4 is about to expand.

The balloon 4 is fluid-tightly connected to it in an upper end region of the tube 3. There, a ball 16 is pushed onto the tube 3, wherein the balloon 4 is pulled over this ball 16. The ball 6 is seated in a passage opening 18 of a holding portion 17, wherein the balloon 4 is clamped between the ball 16 and the upper edge of this passage opening 18. Through the ball 16, a through hole 19 through which the expansion medium flows through the tube 3 in the balloon 4 extends.

The balloon-like body 4 can be a hose formed from a thermoplastic, elastomeric material, which at its lower end, that is to say the end, has the position for positioning in the container 1 to be filled or emptied. is seen, is closed. It thus forms a kind of expanding body, which can be inflated by means of an expansion medium, for example air. The tube has in its unexpanded form an inner diameter which corresponds to the outer diameter of the tube 3 in order to displace the smallest possible volume. The material composition is chosen in terms of wall thickness and elasticity so that the inflated by inflation hose occupies a balloon shape, which fills the inner volume of the container to be filled 1, respectively, the interior of the previously connected components, in particular the volume compensator 2 'and the valve cap 2.

When the balloon 4 is expanded, it not only dresses the container 1, but also the interior of the valve cap 2, d. H. he puts himself from the inside to a through hole 11 and and the valve seats 7, 8 at. In this way, the valve cap 2 before filling completely by ambient air or other, already filled fluid in the case of refilling, be released, so that here also the filling fluid does not come into contact with ambient air.

The valve cap 2 has a liquid valve 5 and a gas valve 6, each with an annular valve seat 7, 8 and corresponding thereto annular closure parts. The valve seat 7 is stationary with respect to a container 1 to be filled, wherein the valve seat 8 is designed to be displaceable with respect to a valve longitudinal axis. The two closure parts are aligned with one another and surround the tube 3, forming a respective annular gap 7 ', 8'. The closure parts of the two valves 5, 6 are arranged in a common carrier 12, which has long been slidable along the valve longitudinal axis. The valve cap 2 can be multi-part and to be divided into different units. The units are surrounded by housing parts 21, 22, 23, 24. In this case, the different units in the housing parts 21, 22, 23, 24 are moved relative to each other along the valve longitudinal axis to open individual valves 5, 6 or both. Furthermore, a liquid feed line 5 (shown only schematically) is connected to the valve attachment 2.

At the free end of the tube 3, but still surrounded by the balloon-like body 4 is a stopper 13, which serves to protect the sensitive bottom 14 of the container 1, and to prevent the free end of the tube 3 from bouncing against this base 14 , The stopper 13 is made of a flexible material, such as rubber. The volume condenser 2 'of FIG. 2 is a body of essentially cylindrical construction, which has a predefined volume VVK in its interior. This volume serves to receive a portion of a defined filling quantity, which is displaced by the tube 3 required for filling, together with the balloon-like body 4, out of the container 1 which is actually to be filled. Accordingly, this volume of liquid absorbed in the volume condenser 2 'can follow after pulling out the tube 3.

The different components now form volumes of different sizes:

The container 1 encloses a volume V _B. The inner bore 1 1 of the valve cap 2 forms a volume VVA. Further, by the liquid valve 5, a volume VVF and, if, as in Fig. 2, a volume condenser 2 'is used, formed by this a volume VVK. All these volumes should be totaled to obtain a total volume.

The volume Vßaiion formed by the tube 3 including the balloon-like body 4 is deducted from the sum of all other volumes, since this volume yes displaces fluid within all components including containers. This results in a nominal volume VNenn = VB + VVA + VVK + VFV - Vaiaiion whose volume size corresponds to that of the actual fluid to be filled. The sum of the volumes of the various attachment components corresponds to the volume Vβaiion within the filling device displaced by the tube 3 as a whole. The nominal volume V enn is achieved by the nominal height to be achieved iNenn, as shown by way of example in FIG. The displaced by the balloon-like body 4 volume in the container 1 is determined by the length h _Ba ion, as far as the tube 3 projects with the balloon-like body 4 in the container 1. The displacement volume of the components projecting in the container 1 corresponds to the residual volumes in the attachment minus the displacement element. It thus results per container 1 always the same level height at (minimum) varying filling.

The above-mentioned method thus proceeds as follows, for example, wherein the sequence with each embodiment, be it with or without a volume condenser 2 ', is the same:

An underside of the attachment is placed in a fluid-tight manner on the respective container 1. After that, the displacement element, ie the tube 3 with the balloon-like body 4 introduced, this being introduced so far that the stopper 13 does not touch a bottom of the container 1 or touches it. Further, the gas valve 6 is opened, so that the expansion medium can penetrate into the balloon-like body 4 and expand it, whereby it removes a large part of the ambient air from the container 1. The balloon-like body 4 rests on the inner wall of the container 1 in such a way that along its length, where there are webs, a gap remains, which provides a fluid or air path.

As soon as the balloon-like body 4 fills the internal volume formed by the individual cavities of the components, the liquid valve 5 is opened. Due to the gap present, fluid can enter it. Meanwhile, the expansion medium is discharged from the balloon-like body 4 again, so that it contracts and rests against the tube 3. The remaining volumes, which arise in the attachment, in particular in the valve attachment 2 and a possibly used volume compensator 2 ', are filled with fluid, so that the container 1 except for the section of the tube 3 together with the balloon-like body 4, which in the liquid protrudes, is filled. The volume which occupies the tube 3 together with the balloon-like body 4 in its unexpanded state within the container 1 corresponds exactly to the volume which is formed by the abovementioned residual volumes in the adsorber, the liquid valve 5, etc.

Once these volumes are flooded, the liquid valve 5 is closed and the tube 3 pulled out. In this case, the aforementioned fluid-filled volumes "slip" and flow into the container 1. This ensures that exactly the aforementioned section now also filled with fluid and per filling a constant nominal volume VNenn and thus a correlating constant nominal height h hen can be achieved However, the abovementioned statement relates only to one and the same container, namely in the sense that easily reproducible filling accuracies can be achieved with the apparatus according to the invention. <br/><br/> [0006] In the case of different containers, however, according to the invention an automatic and measuring medium-free adaptation takes place so that they are filled with different volumes to always get the same level.
