The bottle filling machine 1 shown as a whole in FIG. 1 has a suitable conventional stationary one Central support 2, which carries a conventional filling table 5 in a horizontally rotatable manner. This filling table J in turn carries on the edge a larger number of bottles or other containers 4, which as a result with the table can perform about a full turn. The empty bottles 4 are in a known manner the table J5 fed and from this after filling for further treatment in accordance with generally known bottle filling processes taken. In any case, the filling table 3 is set in rotation by drive arrangements not shown, as a result of which a larger number of bottles 4 arranged on it, guided along the individual filling points 5 and after Completion of the filling process can be removed from the table. A larger number of individual filling units 5 sits in certain distances on the edge of an upper support cross or a disc 6, with the individual recording points of the bottles on the table 3 match. These Support disk 6 is mounted in some suitable manner on an upper column or sleeve 7 and moves with this, which is connected to a lower Sppportrohr 8, the latter in turn on the upper end of the Middle supports 2 of the machine frame is rotatably mounted.

Around the filling table 3 for feeding and removing the bottles to be driven in accordance with the movement of the associated arrangements not shown here are of course corresponding Drive devices provided.

The beverage to be filled into the bottles or containers respectively. the corresponding liquid, is of any one well-known feed device fed into the machine through a central pipe 9 within the central support and flows from this pipe to a manifold 10 at the upper end of the pipe 9. At this manifold 10 are a larger one Number of feed lines 11 connected, which each run to the individual filling points 5.

One of these filling stations 5 is shown in detail in Figures 2, 3, and 5 h _Λ are visible during certain connectors of FIG. 1 The actual filling head 13, which is designed as a cylinder, is removably attached to a suitable carrier 12, which in turn is attached in a suitable manner to the support star 6 at precise distances from one another in a manner known per se. Each of these supports 12 has a vertically running slot 14 (FIG. 3) and a cylindrical part 15 running vertically downwards with a central bore 16. In order to enable the filling heads 13 to move with respect to their carriers 12, a suitable member, for example an air spring bellows 17, is pushed telescopically on the outside of the cylinder 15 and can be moved downwards. A suitable pressure medium is introduced, for example, via a line 18 through a bore 19 in the carrier into the upper end of the central bore 16 in the cylinder 15. A piston 20 is preferably connected to the lower end of this cylinder 15 or is formed as part of the cylinder which is fastened to the carrier

109811/0123

and has at least one opening 21. A piston rod 22 protrudes vertically downward from this piston. The air suspension bellows 17 has a lower cover plate 23 * which can also be formed as part of the bellows and the piston rod 22 tightly encloses so that the Piston rod 22 in this lower cover 25 is pressure-tight can go up and down. The lower end of the piston rod 22 is normally on a foot portion 24 at the lower The end of each carrier 12 is attached. The air suspension bellows can therefore be moved back and forth on a vertical axis. Normally, the bellows 17 is opposite the cylinder 15 extended.

As a special feature of the invention, 1 devices are provided in the aforementioned bottle filling machine which the position of each Fülikopfes 13 to his Carrier 12 is controllable. So is a suitable guide or roller 25 on a pin on the carrier 12 next to his upper end and an identical roller 26 mounted on the bellows 17 by means of a pin 27 and protrudes from its lower end laterally in the slot 14. The position of the bellows 17 is then determined by an external organ, in the case of the one shown Exemplary embodiment a substantially flattened C-shaped Cam plate or a corresponding ring 28 controlled which in any suitable manner with the machine 1 is connected, for example, by an arm 128 and associated devices (not shown) in such a way that that it can be locked in a vertically adjustable position relative to the support star β and is carried by the star will. This curve plate respectively. the hang is 28 naturally designed as such a long bend that it can fulfill its function properly. Preferably

108611/0123

this cam plate 28 is adjusted vertically by resting on the upper rollers 25. Therefore, when the support 6 moves vertically on its shaft 7 to adjust the machine for filling containers of different heights, this cam plate 28 automatically slides up and down with the filling heads while the support 6 moves to maintain its precise operating position. As can be seen in particular from FIGS. 2 and 5, the lower leg 29 of the cam plate 28 supports the lower roller 26 and the arcuate movement of the support relative to the associated filling heads can consequently be used to remove the lower roller 2.6 from its left-hand side 1 to move the lowest position shown in the uppermost position, which is the same as the limit position shown on the right side of Figure 1 for the air spring bellows 17 and the parts connected to it. As a result, the various air suspension bellows 7 can be moved into their uppermost positions during the cyclical movement of the filling table 3 with the bottles or containers 4 on it, while they are expanded during the first part of the arcuate movement of the filling table 3. All of this will be described in detail below during the explanation of the operation of the machine according to the invention.

As a further feature of the invention, there is an open pressure control valve 30 in the upper part for each individual filling head IJ of each filling head provided. As FIG. 2 shows, a suitable bore 31 is provided in each of the supports 12, which runs horizontally into the carrier from the side. The gas required to generate the counter pressure

10981 1/0123

- Tl -

is supplied via a line 32 (Figure 1) from a suitable distributor 33 from the carrier, so that the gas through flows through the carrier via a suitable bore to the inner end of the bore 31. Within this bore 31 a valve piston 34 is inserted in a gas-tight manner so as to be axially displaceable. This valve piston 34 has a suitable blind bore 35 at one end and an outlet bore 36 as a radial connection between this blind hole and the piston skirt. A suitable organ, for example a spring 37 * is between the inner end of the valve piston 34 and the corresponding closed end of the bore 31 is arranged and pushes the piston axially outwardly to the bore 36 with an outlet bore 38 at the top of the To bring carrier 12 in accordance. Consequently this back pressure control valve 30 is normally open. The position of the valve piston 34 brings the same cycle with the movement of the individual filling heads 13 accordingly the movement of the support 6 a cam roller 39 »which in a suitable manner on an axially outward protruding end of the valve piston 34 is mounted, in engagement with a corresponding curve or control rail 40, which sits on the curve plate 28 and from this protrudes upwards so that it comes into engagement with this roller 39. The valve piston 34 is moved axially pushed inside and closes the valve to shut off the supply of back pressure gas to the filling head 13. These Valve control is particularly important when the individual filling heads as in Figure 1 on the right Side shown, have been raised, i.e. when a full container is separated from its filling head and a the empty bottle is pushed under the filling head. As will be described in detail later, the

10981 1/0123

of the individual filling heads 15 in the various filling points 5 by placing the lower end of the filling head terminated on the top of a container for filling the same.

According to the invention, there is a further control for the supply of the counterpressure gas as a function of the precise connection of the filling head with the container underneath. For this additional control is a stop plate 41 pivotably hinged at one end to a pin 42 of the carrier 12, so that they resiliently on the carrier and somehow suitable devices, which are not shown here, can be moved downwards to a limited extent relative to the carrier. This stop plate 4l has at one end a slot 43 * which runs over a shaft 44, however not exactly aligned with this, on which the cam roller 3? is stored. This shaft 44 is in turn seated in a slot 45 in the carrier 12 so that they are with the valve piston 34 during control by the rail 40 moves.

For reasons to be explained in more detail below, each individual filling head 13 has a supply line 46 for the back pressure gas, which normally goes through the head and protrudes from both ends.

As a further control, a control rod 146 is attached to the upper end of the bellows 17 and protrudes through corresponding de openings in the support 12 and the stop plate 41 · At the upper end of this rod 146 there is, for example, one 3 washer 47 »which through a spring 147 against a collar

109811/0123

the rod is pushed. Normally, this disc 47 does not move that far with the individual filling point below that it touches the stop plate 41, since the downward movement of the corresponding filling head by engagement interrupted with a properly standing container. However, if there is no container on the filling table, on which the filling head 13 in question can be placed, moved this extends further down beyond its normal low position, whereby the disc 4? strikes against the stop plate 41 and press it down. Such a movement of a filling head only occurs when the back pressure control valve 30 is closed with the slot 43 in the stop plate 41 receives the upper end of the shaft 44 and holds the valve closed. Any inaccurate downward movement a filling head 13 'which is indicated by the contact of the disc 47 on the stop plate 41 holds the control valve 30 is closed, so that an escape of Back pressure gas from the corresponding supply pipe 46 is prevented. The stop plate 41 keeps the valve closed, until the full work cycle of the associated filling head has expired, whereupon the cam disk 40 at next lifting of the filling head in question in the carrier 12 through the cam plate 28 in the uppermost position, the cam roller grabs and pushes inward. Usually, the stop plate 41 is also taken from the upper end of the shaft 47 at the same time released as soon as the cam rail 40 grips the cam roller 39 to sole the valve, and springs spring in the open position.

FIGS. 6-10 show the structure of the individual, expediently cylindrical filling heads 13 of the filling machine according to the invention. Every single filling head

109611/0123

consists of a suitable housing which is designed, for example, as a two-part cylinder 50 and whose lower and upper cylinder parts are pushed into one another and secured by a fuse or a centering pin 15 and / or through the end of a beverage feed valve be held together. This feed valve 52 is with one of the lines 11, which supply the beverage to the individual filling heads, connected and preferably in the Trained in a way that it is automatic and instantaneous closes as soon as it is no longer with the cylinder 50 in Engagement is. However, when the feed valve is in engagement with the cylinder in the operating position, it is automatic opened, so that the beverage flow into the interior or the bore of the cylinder 50 and from there into the individual Bottles can flow.

Figure 6 shows particularly clearly that the lower end of the cylinder 5 has a seat 53 with which the cylinder is placed on the container to be filled and which preferably consists of a flexible, circular ring-shaped Part consists, which is used in a corresponding recess in the lower end of the cylinder 50 is. This seat is pressed onto the top of a bottle or other container and seals the Filling head opposite the container. At the same time, the seat 53 dampens the impact that occurs when it hits directly of the metal cylinder on a container.

The cylinder 50 has a through central bore 54, which forms a connection to the seat 53 receiving the container and through which the beverage is connected to one Container flows through.

109811/0123

H,

Appropriate organs are provided within the cylinder to ensure that the drink only flows downwards, for example, a constricting sleeve 55 is firmly inserted in the cylinder between its ends, which one Has side bore 56 into which the inner end of the Feed valve 52 is used, so that the drink through this opening can flow into the interior of this sleeve 55. In this sleeve 55 is a guide sleeve 57 with some places smaller outer diameter than the inner diameter of the sleeve 55 and used with the sleeve for example firmly connected by a clamping nut 58.

To the pressure on the flowing through the cylinder 50 To reduce drink, several locking sleeves, in this case five conical sleeves 59 * on top of each other between the two sleeves 55 * 57 arranged, with them between corresponding Surfaces of this sleeve are pressed together. Each of these sleeves 59 has longitudinal ribs 60 or the like. On the outer surface, which extend the entire length of the sleeve, whereby the ribs 60 the individual sleeves Arrange them close to one another, but with a certain gap of about 0.1 mm. At the top of each sleeve 59 a short slot 6l running in the longitudinal direction is formed, opposite which a short inner rib 6la is provided, which is slightly longer than this slot 6l. The individual sleeves are offset from one another by 180 °, so that the inner rib 6la of the one sleeve engages in the slot 61 of the next sleeve, so that the sleeves to align to each other and to hold axially. As a result, the drink can through the stacked Sleeves 59 flow down from above, relieving the pressure on the beverage, for example

10 9 8 11/0123

/ f

by 1.8-2 kg / cm, while the drink through the capillary-like spaces between the individual pods 59 flows down, the pressure drop being naturally due to the pressure of the beverage at the inlet of the sleeve 55 and from the back pressure in the container to be filled, as well as on the number of locking sleeves 59 used. This pressure reduction is guaranteed minimal foaming or gas release in the beverage being treated as it is released from the individual Filling head flows out through the lower end of the cylinder 50.

As a further additional element and special feature of the filling heads, a tubular valve spindle 62 is slidingly inserted in each of the cylinders 50. This valve spindle is preferably seated in the bore of the guide bushing 57 * is guided in this and protrudes downwards out of the guide bushing and at the same time upwards over the upper end of the cylinder 50. This valve spindle 62 is near the lower end of the cylinder 50 a valve seat 63 is formed which is in communication with the cylinder bore and the receiving seat 53 of the cylinder. In the illustrated embodiment, this valve seat is designed as a cylindrical blind bore in the central bore of the cylinder and seals with the cylindrical lower end 57a of the tubular valve spindle, for example via an O-ring 64 which is arranged on this spindle near its lower end. In the closed position of the valve spindle, as shown in FIG Filling head can flow into it and in this valve position any flow of drinks through the filling head

109811/0123

-yr -

is prevented. Another feature of the tubular valve spindle 62 is that it has a blind bore 66v at the lower end and a plurality of outlet openings are formed in the wall of the valve spindle, which extend downward and inward and therefore tangential to the blind bore 66. If that is pressed through the filling head Drink has a certain residual pressure, which is, for example, between 0.21-0.28 kg / cm, or if so required higher, then this drink flows through that Openings 67 with a certain force, causing it to rotate receives and initially remains on the wall of the blind hole. When the valve spindle 62 moves into the open position is, the Saokbohrung 66 gradually goes into the bore of the cylinder 50 and the drink flows along the remaining Length of the cylinder down along the wall of the bore. This centrifugal flow of the beverage continues as the drink flows down into the attached bottle so that the drink starts out first whirling along the wall of the bottle or container flows downwards. This lateral outlet vortex of the beverage is reinforced by a conical shield 1? 2, which under the receiving seat 53 is attached to the feed pipe for the counter pressure gas.

The position of the valve spindle in the filling head is controlled by suitable members, for example a piston 68, which is fixed to an upper portion of the valve stem in the NHhe \ of the upper end of the cylinder 50 and the bore <of this cylinder is sealed against. Normally the piston is moved to its uppermost position by pressing it against the cover of the cylinder, for example by means of a spring 69 which is in the cylinder bore

109811/0123

- IS'-

is inserted and rests against the upper end of the sleeve 55. A pressure medium, two-way compressed air or the like., is fed to the cylinder 50 through a conduit 70 via a fitting 71 in the upper part of the cylinder and presses on the piston 68 from above. Therefore, if via the line 70 from above, on the piston 68 Working pressure is exerted, the valve spindle 62 is moved very quickly from its closed position to the open position, while it is very quickly pushed back into the closed position when this pressure is switched off.

As FIG. 6 shows, the feed pipe 46 for the counterpressure gas extends over the entire length of the cylinder 50 and protrudes out of the cylinder both at the top and at the bottom. Usually the metal pipe 32 is the back pressure gas feeds, covered over the entire length with an insulating sleeve, which up to a contact 73 at the lower end of the pipe runs. The back pressure gas pipe provided with the coating 72 46 is fixed at the upper end of the valve spindle 72 by a locking nut 74 and can be moved into Adjust its height to the required level of the container to be filled. In the upper part of the tube a scale or corresponding setting marks is expediently attached to this setting of the pipe to facilitate.

As a further feature of the invention, the filling cylinder 50 has a differential pressure switch 75 near its lower end. This differential pressure switch or the valve 75 is under a corresponding pressure via a line 76 or via spring pressure and is of this type built up that it is in one or the other end position

109811/0123

embarks, depending on whether on the valve from the opposite the counter gas pressure acts. For this purpose, the valve 75 is connected to an opening 77 in the cylinder 50 and the Counterpressure built up via the line 46 in the container to be filled flows upwards and via this opening 67 in the valve 75 to control its operation.

In the figure 1 a form of a control device 80 is shown schematically, which is connected to the filling machine according to the invention. Such control devices are preferably electrically operated and have corresponding circuits to fulfill the functions described in detail below, as well as a suitable power source, not shown, which is connected to this control device 80. The differential pressure filling element, usually the valve 75, is connected to the control device 80 via one or more lines 8l, whereby this is set to a certain operating state according to the exact counter pressure which is transmitted to it through the bore 77 on the part of the container attached to the filling head 13 , adjusted valve can transmit the exact information to the control devices 80 via the line %% or via the lines 8l, so that the filling head IJ> can be adjusted for the flow of the beverage. The pressure acting on the piston 68, which is supplied via the line 70 (Figure 6), is controlled by a special element, for example a magnetically or electrically operated control valve, which is designed as a switch or another filling element 82, which in turn is connected to a corresponding pressure medium source, for example a compressed air source, is connected via the line l82. If therefore

109811/0123

the valve 82 is precisely adjusted, for example by receiving electrical pulses via one or more lines Lines 83 which are connected to the valve 82 and proceed to the controller 80, then the valve 82 is actuated to open or close and thereby supplying a pressure medium to the piston 68 or withdrawing it from it. This ensures that the Operating pressure is transmitted to the piston 68 only when the differential pressure switch 82 has the exact back pressure is fed and a corresponding information is transmitted to the control device 80, which thereby welbhe the valve or energizes switch 82 and depresses plunger 68, around valve ports 87 in the tubular valve stem 62 to open so that the drink can flow through the filling head 13.

The flow of beverages through the individual filling head must of course be switched off when the container engaged with this filling head has been filled to the desired filling level. For this purpose, the switch 72 provided at the lowermost end of the counter-pressure gas line 46 is connected to the control device 80 via the metal core of this line 46 and a line 84 connected to it, while the metal frame of the machine 1 is also connected to the control device 80 via a line 85, so that there is an open circuit between lines 84 and 85. This circuit is closed as soon as the liquid level in the container 4 has reached the line 86 in FIG. 6 and thus touches the contact 73. This closes a circuit via the electrically conductive drink flowing into the bottle 4 along its walls, which in the remaining part nooh with the

109811/0123

Metal parts of the filling head Y $ is in contact, whereby a switch-off pulse is transmitted to the control device 80 and the valve 82 is actuated so that the valve spindle 62 snaps into the closed position.

If the filling level of the bottle 4 is to be adjusted, the clamping nut 74 only needs to be loosened and the back pressure gas tube 46 to be adjusted vertically in the filling head to the appropriate height. When switched off of the inflow of the drink naturally flows in the lower At the end of the bore 54 under the valve spindle 62, the amount of beverage still present in the bottle, whereby this However, the amount always remains constant, so that the final fill level, which is indicated in FIG. 6 by the line 87 is reached in the bottle 4 when it is separated from the filling head. In the lower part of the counter-pressure gas pipe 46 If desired, a plurality of outlet openings 88 are provided through which the counter-pressure gas can enter the bottle unimpeded or can enter the container. Usually the pressure of this gas is around 0.4 kg / cm, in any case lower than the final pressure of the beverage as it flows through the. Filling head 13.

For the connections between fixed air pressure, pressure medium or liquid feed lines with circumferential Parts of the machine can be provided with a wide variety of known types of revolving or sliding clutches will. Usually the individual compressed air pumping organs for the supply of the switches 75 when using compressed air connected to a corresponding distribution pipe, from which the individual filling heads can be verified. In the same way, a

109811/0123

Manifold that deals with the moving part of the machine moves, provided for the supply of the back pressure gas, which via common couplings in the machine with the corresponding gas is supplied.

In any suitable manner, a pipe distributor 89 is attached to the support 6, which is connected to a not shown Pressure medium source is connected and is connected to the individual filling heads via the lines 18, which on Carrier 12 are connected. As a result, compressed air or another pressure medium is continuously in the bores 16 fed to the carriers and flows into the central bores 16 or out of them, depending on whether on the air spring bellows 17 a pressure is exerted or not from the outside by the cam disk 28. Some of these parts are shown schematically in Figure 1, but generally provided commercially available devices for this purpose are.

The individual filling heads 13 are preferably designed as units formed, which can be easily attached to the carriers 12 or removed from them. The attachment is can be seen particularly clearly from FIG Approach 92 on the air suspension bellows I7 protrudes. A curved surface 93 of this toggle arm 90 engages a clamping plate 94, which rests with one end of the extension 92 and the filling head against a circular arc-shaped seat on the circumference of the Sleeve 17 pushes so that it can move with it, but slightly can be resolved from it.
