Patented in the German Empire on January 13, 1906.

The invention relates to a bottle filling device, in which the bottles for the purpose of simultaneous filling of a number move the same constantly around a common axis and return to the starting point filled, where they are · removed.

In the subject matter of the invention, only the insertion of the empty and removal takes place of the filled bottles by hand while

ίο pressing the same against the discharge nozzle, as well as the control of the filling tap is effected automatically by means of compressed air. For this purpose there is a special filling device and pressure cylinder for each bottle provided, which is also designed as a control cylinder. This contact pressure and control cylinder is provided with two pistons, one of which for pressing the bottle to the outlet nozzle, the other is used to reverse the tap; here the access of the compressed air to the control piston is regulated so that the open and Always close the tap in good time and only when someone is present Bottle takes place, whereby a loss of filling liquid is completely excluded. To the Pressing the bottles against the filling tap is now also otherwise without compressed air The aid of pressure springs has been used; however, with these devices always only one bottle filled, which is why the filling device does not rotate; there is also the. Pressing the Bottles to the filling tap the air escaping when filling the bottles is used, which should be sufficient for this purpose, but not sufficient to control the filling valve and which must therefore be done there by hand. Compared to these devices, the object the invention mainly the advantage of a greater efficiency and then protects the same by always timely automatic opening and closing of the tap in the safest way before anything Loss of filling liquid.

The object of the invention is shown in the drawing in an exemplary embodiment shown on a device for filling beer.

The revolving device for filling the bottles is carried by a hollow stand α through which the likewise revolving beer riser pipe b leads, which serves as a drive for the filling device

is used and is set in slow rotation, for example by means of worm and worm wheel c. The beer riser pipe b carries a container d at the top, from which the beer flows continuously to a number of filling taps e known per se. The bottles y are pressed firmly against the mouthpieces of these taps e with the help of special pistons q moved by compressed air ίο these devices are all the same; it be therefore only one of these is described below. The piston q moves in a cylinder p 'and carries a tube ο which has a head η serving as a bottle carrier at the top, by means of which the bottles are pressed against the mouthpiece of the tap e. Furthermore, a second piston r is arranged in the cylinder ρ , which is used to control the cock plug χ ; For this purpose, it is firmly connected to a rod s guided in the piston q , which is connected to the plug χ by means of the double-armed lever u rotatable about the bolt ν and the push rod w , so that depending on the position of the piston r the tap e is open or closed. To move the pistons q and r , compressed air is used, which is first fed through a pipe g (Fig. 5) to a distribution cone f on which the entire rotating device rests with the aid of a correspondingly conical twisted sleeve i attached to the riser pipe b. Arms / are attached to the sleeve, each of which carries a cylinder ρ. The compressed air used to control the pistons q and r is passed through two lines m and m ^l located in each arm / from the cone f into the cylinder ρ , the lower line m below the piston r and the upper line m ¹ between it and the piston q opens. The air enters the cone f through the supply line g and is formed by two-part grooves h and h ^l , which run horizontally at the point in time when the bottles are pressed and the tap e are reversed and provided with ducts leading to the outside, as well as through the Passages k and A: ¹ provided in the sleeve i are fed to the lines m and m ^l , which are connected to the cylinders ρ . The operation of the device is as follows (Fig. 6): The removal and insertion of the bottles y always takes place at the same place, so that the worker does not have to leave his place. After an empty bottle y is placed on the head η of a tube 0, the passage k ^{l of} the sleeve i first meets the associated groove h ¹ in the cone / (1-1), ie compressed air ^{enters through the line m 1} Cylinder j> a, above the piston r (Fig. 1), while there is still compressed air pressure under the same, as a result of which it cannot move downwards, ie the cock e remains closed. The piston r thereby forms an abutment for the compressed air flowing in through line m ^l , which consequently pushes the piston q upwards, ie presses the bottle j- 'against the cock c . Immediately thereafter, the passage k of the sleeve i also reaches its groove h, namely at a point (2-2) which allows the compressed air located under the piston r to escape into the open, causing the piston r to pass through the one located above it Pressure is pressed down and the cock e reversed, ie opened (Fig. 3). If the bottle is now full, the passage A: ^{1 has} reached a point (3-3) which allows the air above the piston r to escape gradually while the compressed air pressure prevails under it again. As a result, the piston r, following the air escaping above it, is pushed upwards and closes the cock e without the piston q being able to lower itself, because the space that is to a certain extent freed by the escaping air is filled by the piston r, which move up a corresponding piece; the bottle ^ thus still remains pressed down. When the cock e is completely closed, the piston q is gradually lowered by its own weight as the compressed air under it escapes and allows the bottle (4-4) to be removed, which has returned to its original position. * There is also a device which prevents opening of the tap e when the worker has not inserted a bottle (Fig. 2). For this purpose, the rod s of the piston r extends through the piston q and is provided with a head t at its upper end. If no bottle has now been inserted, the piston q can move higher than usual and, as a result of the arrangement of the head t, takes the piston r upwards or upwards. prevents the same from moving downwards, so that in this case the valve β remains closed (FIG. 2). Instead of the compressed air, any other pressure medium could of course also be used in the case of only insignificant changes to the system. Godfather ν τ-An Proverbs: i. Bottle filling device with bottle holders that can be lifted by compressed air and Rotatable bottle rack, characterized in that a second piston (r) is arranged in the cylinder (p) known per se for the piston (q) for pressing the bottles, which is used to reverse the filling tap (e) , the two pistons by means of a fixed, with appropriately designed grooves provided compressed air distribution member (f) are controlled so that their movements are dependent on each other and the opening and closing of the tap can only take place when a bottle is present. 2. Bottle filling device according to claim i, characterized in that the piston (r) used for reversing the filling valve is prevented from moving downwards when the bottle is not inserted by the piston (q) , which in this case goes higher and serves to press the bottles, whereby a opening the tap in the absence of a bottle is impossible. 1 sheet of drawings.
