PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung bezweckt, bei Maschinen zum Füllen von Flaschen mit kohlensauren oder anderen gärenden Flüssigkeiten die Schaumbildung dadurch zu verhindern, daß die Durchflußgeschwindigkeit der Flüssigkeit fortwährend verringert wird, während das Volumen der fließenden Flüssigkeit gleich bleibt.The present invention aims at machines for filling bottles with carbonate or other fermenting liquids to prevent foam formation by that the flow rate of the liquid is continuously reduced, while the volume of the flowing liquid remains the same.

Die Schaumbildung erfolgt beim Bier oderThe foam formation takes place with beer or

ίο ähnlichen Flüssigkeiten durch das Entweichen der Kohlensäure. Die im Bier befindliche Kohlensäure ist auf zweierlei Weise entstanden, nämlich einmal durch Gärung und zweitens durch künstliches Hineinpressen in das Bier.ίο similar liquids by escaping of carbonic acid. The carbon dioxide in beer was created in two ways: namely, firstly through fermentation and secondly through artificial pressing into the beer.

Letztere hat das Bestreben, bei atmosphärischem Drucke unter Blasenbildung zu entweichen und kann ausschließlich durch Gegendruck daran gehindert werden. Die durch Gärung entstandene, inniger gebundene Kohlensäure dagegen hat das Bestreben, in die Atmosphäre zu entweichen, in viel kleinerem Maße. Infolgedessen ist eine geringe und vorübergehende Berührung der Flüssigkeit mit der Atmosphäre lange nicht von der nachteiligen Wirkung wie z. B. bei künstlich eingepreßter Kohlensäure. Daher kommt es, daß z. B. das kleine Röhrchen /?⁴ im Flaschenstöpsel (Fig. 4) bei Selterwasser genügen würde, um die alsbald frei werdende Kohlensäure herausspritzen zu lassen, während beim Bier die Kohlensäure unter Hervorbringung einer geringen Spannung gebunden bleibt und der im ersten Augenblick sich entwickelnde und in das Röhrchen fr⁴ aufsteigende Schaum genügt,.um dasselbe zu verstopfen und eine weitere Schaumbildung zu verhüten.The latter tends to escape with the formation of bubbles at atmospheric pressure and can only be prevented from doing so by counter pressure. The more intimately bound carbonic acid produced by fermentation, on the other hand, tends to escape into the atmosphere to a much lesser extent. As a result, a slight and temporary contact of the liquid with the atmosphere is not long from the adverse effect such. B. with artificially injected carbon dioxide. Hence it happens that z. B. the little tube /? ⁴ in the bottle stopper (Fig. 4) with Selterwasser would be sufficient to let the carbonic acid that is soon released squirt out, while with beer the carbonic acid remains bound by producing a slight tension and the foam ^{that develops at the first moment and rises into the tube for 4} sufficient to clog it and prevent further foaming.

Somit wird zwar nicht ein theoretisch absoluter, wohl aber ein praktisch vollkommen ausreichender Luftabschluß erzielt. Infolgedessen wird zwar eine zur Schließung des Luftröhrchens /z⁴ notwendige Schaumbildung stattfinden', doch ist dieselbe so gering, daß man praktisch doch noch von einer fast vollständigen Verhinderung der Schaumbildung sprechen kann.In this way, although not a theoretically absolute, but practically completely sufficient air seal is achieved. As a result, although held a necessary to close the air tube / z ⁴ foaming ', but is the same so low that one can speak of an almost complete prevention of foaming practically yet.

Während nun die durch Gärung entstandene Kohlensäure im Ruhezustand der Flüssigkeit bei Druckentlastung und Berührung mit der atmosphärischen Luft nicht ohne weiteres Schaumbildung bewirkt, kann solche auf rein mechanischem Wege durch Erregung der Flüssigkeit hervorgebracht werden, denn es ist bekannt, daß die Reibung von Bier an ungeglätteten Stellen, an Verengungen und Widerständen ohne Zutritt der Atmosphäre Verschalung des Biers herbeiführen kann. Dies nun bei einer Flaschenfüllvorrichtung möglichst zu verhindern, ist der Zweck der vorliegenden Erfindung. .While the carbonic acid created by fermentation is in the idle state of the liquid not without further ado when the pressure is released and in contact with the atmospheric air Causes foam formation, such can be done in a purely mechanical way by exciting the Liquid can be produced, because it is known that the friction of beer at unsmoothed areas, constrictions and resistances without access to the atmosphere Can bring about casing of the beer. This is now the case with a bottle filling device To prevent it as much as possible is the purpose of the present invention. .

Fig. 2 is a side view and
Fig. 3 is a vertical section of the same, Fig. 4 is a cross section through the filling head,

FIG. 5 shows a longitudinal section through the receiving cylinder B along line 5-5 of FIG.

7 and 8 show a view along with a section through the connecting piece between the siphon pipe and dispensing cylinder C,

Figure 9 is a reduced perspective view of part of the movable frame for the bearing cushions on the lower part of the siphon tubes and

FIG. 10 shows two vertical cross-sections through the feed tube of the dispensing cylinder C along lines 10-10 in FIG. 6.

A frame A consisting of two vertical side parts A ¹ carries a receiving cylinder B and in front of this a delivery cylinder C.

The head part of the receiving cylinder B is provided with two feed tubes bb to be closed by taps b ^l , so that any connection with one or two barrels can be made.

Each feed tube has b b ^'2, a transparent glass end, which shows the flow of the liquid and its nature during the inflow into the receiving cylinder B. The same has the same diameter as the supply pipe b, while the supply tap b ^{l is} slightly enlarged towards the receiving cylinder.

That the. The pipe e discharging liquid from the receiving cylinder has a slightly larger diameter than the supply pipe bb and is connected by a further flexible pipe E to the outer end of the pipe E ¹ opening into the dispensing cylinder. The latter is provided with a stopcock e ¹ , the bore of which widens towards the drain pipe E ¹ and is slightly larger in diameter than pipe e and the flexible pipe .Eist. The drain pipe E ^1, in turn, is somewhat larger than the hole in the stopcock e ¹ . It ends near the opposite head part of the dispensing cylinder C (Fig. 6) and has on the lowest side an incision e ' ² (Fig. 6 and 10) running over the entire length of the tube, through which the liquid is at an oblique angle against the curved inside of the Cylinder C runs out evenly, so that foam-generating movements are almost completely prevented. The siphon pipes carry filling heads h in a known manner (Fig. 4), which are provided with a short, finely perforated exhaust pipe / 2 *, to which a small rubber pipe h ^{5 is} connected so that the air can escape from the bottle to the outside during filling . "

The bottles to be filled are supported in the known manner on the floor by a crossbar H and held under the neck by a support H ¹ provided with incisions. ■

The liquid in the receiving and dispensing cylinders B and C is under the pressure of carbonate gases, which can either be fed directly into the upper part of the barrel or vessel or by means of a gas-distributing cylinder L, which is connected to the receiving cylinder B by a suitable device or attached to the frame A (Fig. 3).

In order to keep the friction of the liquid as small as possible as it passes through the device, each subsequent pipe through which the liquid flows is of greater internal width than the previous one, while the taps are provided with conical passages that widen in the direction of flow . The sum of the diameters of all siphon pipes is greater than the outflow mouth of the pipe E ¹ in the dispensing cylinder, so that the liquid on its way -through the filling device always gradually passes through increasing cross-sections and nowhere encounters foam-inducing resistance. The natural tendency of carbonic acid to escape from the liquid is finally counteracted by subjecting the liquid to sufficient gaseous or pneumatic pressure and exposing it to it for as long as the liquid continues to flow while the bottles are being drawn off and filled takes place.

Even if the word "bottle" is used for brevity, it is not the application of the invention is limited to bottles, but it can just as well also for filling from any larger container to a smaller one, e.g. B. can be applied from a tank to a barrel. Any other carbonated or fermenting liquid can also be used instead of beer be used.
