UNITED STATES ATENT OFFICE FLUID OPERATED FILLING VALVE MECH- ANISM UTILIZING VARYING FLUID PRES- SURES 24 Claims.

My invention has for its object a machine for filling bottles and the like containers, the filling nozzles of the machines being provided at least with:

(a) a member carried by said filling nozzle and closing the neck of the container to be filled during the filling stage thereof,

(b) a pipe or channel feeding the liquid into the container during the filling stage.

a tube for setting the inside of the container to be filled in communication either with the inside of the vacuum chamber of the machine considered or with the inside of the chamber of any compressed gas of said machine;

The invention relates to those filling machines that include moreover either means for moving the container or containers to be filled towards or away from the filling nozzle or else a similar movement of the filling nozzle or nozzles with reference to the container or containers.

The invention relies on the principle of applying a plurality of difierent pressures in succession for urging the neck of the container to be filled against the closing member carried by the filling nozzle, generally made of rubber or the like plastic material; these different and successive pressures are associated with the relative movement through which the container is moved towards or away from the filling nozzle in a manner such that each of the successive different pressures may correspond to one of the stages required for the complete execution of the filling operation desired.

The invention is of considerable interest in a large number of cases inasmuch as it provides for the possibility of giving each of the separate stages defined by the succession of difierent pressures associated with the relative movement between the container and the filling nozzle, a duration as long as maybe required.

This feature is of great advantage in the case of machines filling containers through application of vacuum with a liquid that shows a tendency to frothing as the invention allows in this case leaving the neck of the filled container in fiuidtight contact with the member closing the filling nozzle, the liquid feeding channel being closed as long as may be required. This leaves enough time for the Suction in the nozzle to absorb the froth or excess liquid to be found in the container. Such an application is of particular interest in the case of machines filling milk bottles chiefly when the liquid is bottled at a low temperature and has consequently a tendency to froth.

The above mentioned feature is also importan in the case of machines adapted to fill bottles with beer, lemonade or the like sparkling drinks Which are generally of the so-called counter pressure or isobarometric type, the nozzles of said machines being adapted to open and close in a plurality of successive steps:

The first step appears as a consequence of the pressure exerted by the neck of the container to be filled against the closing member for said container carried by the filling nozzle so as to open the tube communicating with the inside of the nozzle with reference to the inside of the chamber of the filling machine that contains a gas under pressure such as CO2.

The second step is then provided again through the pressure of the neck of the receiver to be filled against the closing member of the container carried by the filling nozzle, which has for its result an uncovering of another opening in the nozzle that allows then the fiow of the liquid into said container to be filled.

Such an improvement may for instance be incorporated to machines provided with filling nozzles 0f the type disclosed in my prior French patent, filed on December 21, 1944 and entitled Filling Nozzles for Machines Adapted to Fill Bottles, Flasks and the Like Containers, the lower pressure in the arrangement considered having for its result to overcome first the resistance of the spring closing the valve control-- ling the pipe connection between the inside of the container to be filled with the inside of the machine considered that contains CO2 or the like gas under pressure, the higher pressure having for its object to overcome the resistance of the spring closing the valve controlling the actual admission of liquid into the container to be filled.

According to my invention, the bottle filling machine of the type disclosed in the opening paragraph of the present specification is provided with means for associating a plurality of difierent successive pressures with a view to urging the neck of the container to be filled against the member closing said neck and carried by the filling nozzle, said pressures being applied in succession in'predetermined relationship with the relative movement between the container and the filling nozzle against the antagonistic pressure of one or more springs opposing the opening of ports provided in the nozzle under the action or said pressures.

Further it is possible to use two different presmentioned hereinabove and being substituted afterwards for the higher pressure, such reduction in the pressure allowing the closing of the filling pipe under the pressure of the antagonistic spring, the neck of the filled container remaining then and for a predetermined duration, in fluidtight contact with the closing member carried by the filling nozzle; the relative movement of the container away from the closing member considered corresponding to the termination of any pressure urging the neck against its closing member.

My, invention isalsoapplicable to a vacuum opstated. filling machine wherein the higher; pressure urgingtheneck-againstthe closing member is exerted first so. as. to open the, filling channel while. the lower pressulfeis then substituted therefor after the filling stage, the neck of the filled container remainingin fluidtight contact for a predeterminedv duration with. the. closing member carried; by; th fil ng. nozzle, said duration. corresponding to the, time, required for suckingin the, excesshguid or thegfroth. that may befound mi s-c n a n r.

According to. a further. object. of my invention, there are provided oneormoreports orvents; the cross=sectionof which is. substantially. less than. that of the; tube connecting. the inside of 51. .8 container to befilledtwithithe .vacuumchambe! o f -theIfilllng. machinensaid vents. are provided; in the filling channel .in .a :manner such that saidvents allow a-slightentrance of.- air into the unfilled space of theacontainer'during the closingstageofthefilling and while the filled container remains. in contact with. the closing member carried; by, thefilling nozzle under the actionxof, thejower. of thetwo operating. presmies; theslighteentrancepf air thus allowed-has chieflyforiitsypurpose toiurther the suction t themierfiowontrothzto be foundinthe filled'container- Myginventionis also applicable to afilling! mainline. operating. through counter-pressure- Whe ehkthe-lower.pressureis-first exerted so astogovercome theresistance of a first-antagonistic pring. thatexertsea thrust on the member controlling. the connection between the inside of thescontamer .to .be filledwith the inside oi. :the

Lastly, thedifferent successive pressures: appliedare obtained at the .desiredmoment for each container to beg-filled. a distributor for, fluid under pressure feeding a double acting .fiylinder, the. piston of which is securedei-ther to-the carrier of saidcontainerintha case of a movement of the latter with reference. tov the. nozzle or to the nozzle in the case of the latter being mov able with reference to the container. The distributor considered is provided with channels for receiving and transmitting the fluid under different pressures and it distributes the fluid in succession and in a predetermined sequence under different pressures, each of saidsuccessive distributions of the fluid under a different pressure having an equally predetermined duration.

It is very important to note that the application of different successive pressures for urging the container neck against the closing member carried by the filling nozzle is associated with relative movementsof the container with reference to the nozzle and these movements can only be obtained' in practice through standard mechanical members. It will be remarked on the other hand that for sake of brevity, I will use hereinafter the expression relative movement between the container and the filling nozzle so as to show that the invention is applicable both to machines wherein the container is movable and to those. wherein the filling: nozzle is movable.

in. adifierent operative position-of the machine.

In Figs. 1, 2; andS-the members.- illustr'ated are the stator: of the. distributor of fluid under pressure, tharotor 2 thereof and 3 the double acting cylinder, the piston 20 of which gives the container 4 its movement with reference to the filling nozzle.

The stationary stator i that is freely mounted on the shaft 5 is urged against the rotor 2 keyed to the shaft 5, through a spring 6 or equivalent part.

i designates the pipe feeding the stator I with fluid under high pressure while 8 designates a similar pipe feeding the same fluid under a reduced pressure to the stator I. In this example, the expression high means a pressure above that of the antagonistic spring described hereinafter while low pressure means a pressure less than that of said antagonistic spring. 9 designates a pipe for the outlet of the fluid passing out of the stator I.

In the above mentioned distributor stator, the concentric annular channels It and Il communicate with the channel l2 and are constantly fed by the pipe l with filuid under high pressure.

The channel it is not connected with the other channels (Fig. 2) and it is fed separately by the pipe e with fluid under low pressure.

The concentric channels It and l5 communicate with one another through the channel It. They receive no fluid under pressure and serve only as a passage for the liquid delivered the output pipe 9 With which they are in constant connection.

t should be noticed that the stator I may be held fast against rotation by means of a projection i'l carried by it and adapted to engage a stop l3 rigid with a stationary part of the machine that is not illustrated.

In Fig. l, the pipe 89 operates in alternation to send fluid under high and low pressure underneath the-piston 29 of the cylinder and to receive from underneath said piston the fluid urged towards the distributor.

The pipe 2! sends similarly in alternation high pressure fluid to the other side of the piston 2e and receives from said piston side the fluid to be delivered towards the distributor.

In said Fig. l, the piston rod 22 carries the container to be filled 4 through the agency of a carrier 23. On the other hand, the filling nozzle includes a tube 2% connecting the inside of the container with the inside of a vacuum chamber 46 while a pipe 25 serves for the admission of liquid and is closed by a closing valve 26 rigid with the tube 24 and the neck of the container to be filled is closed by the member 23 rigid with said pipe 25. The latter slides to a slight extent longitudinally of the pipe 24 against the action of the spring 2'].

Small vents or ports 29 are provided optionally in the wall of the pipe 25 feeding the liquid. The cross-section of these vents is much smaller than the cross-section of the tube 24 so as to exert no substantial action on the suction exerted by the tube 28.

They serve as disclosed for furthering the return into said tube 2d of the froth or excess of liquid that may be found at the end of the filling stage in the filled container. Moreover it is possible in certain cases for these vents to prevent adherence through suction of the container neck against its closing member 28.

The operation of the arrangement illustrated in Figs. 1, 2 and 3 is as follows. In the first place, it should be noticed that Fig. 1 and Fig. 2 correspond to the stage of application of low pressure on the neck of the container to urge it against the closing member carried by the filling nozzle.

This stage is defined by the angular location of the rotor 2 with reference to the stator I. As a matter of fact, by reason of the rotary movement of the rotor, the end l9 of the pipe l9 connected with the port 30 of the rotor (Fig. 3) registers at this moment with the channel I3 fed through the pipe 8, fed in its turn by the low pressure supply that is not illustrated and may be constituted by a pump, accumulator or the like means.

Consequently the fluid under low pressure passes through 830-l9 and I3 and acts on the underside of the piston 20 but this pressure is less than that required for overcoming the pressure of the spring 21 and the neck of the container 4 is urged fiuidtightly against the closing member 28 without it being possible for the latter to be raised.

The fluid that is delivered through the other side of the piston 20 passes through the pipe 2| and then back through the port 3| of the rotor registering with it and then through the channel l5 and the exhaust pipe 9 connected with said channel.

The stage correspondingtoapplication of high pressure for filling the container is prior to the application of low pressure and is executed as follows: the port 30 of the rotor 2 was lying first in front of the beginning of the channel II: that is fed in its turn through the channel I feeding high pressure fluid. From this moment onwards and throughout the movement of 'the port 30 over the channel It, the fluid under pressure is sent into the cylinder 3 through the pipe I9 and exerts said pressure on the underside of the piston 26 that transmits it to the container, the neck of which is urged against the closing member carried by the filling nozzle. But at this moment, the pressure against said member being higher than that of the antagonistic spring 2?, the latter yields and the pipe 25 is no longer closed by the valve 26, whereby the filling operation may be executed.

The stage corresponding to the movement of the filled container with reference to the filling nozzle follows the two preceding stages. It is defined by the passage of the port 3| of the rotor 2 in front of the channel II that is fed through the pipe i communicating with it through the channels l2 and I0.

At this moment, the fluid under pressure passes through ll0l2 and H andthrough 3| and the channel 2| so as toreach the upper side of the piston 2| to constrain the latter to sink. At the same time, the fluid delivered by said piston 20 passes downwardly through I9, 30, I l (registering with 36) I6 and I5 and lastly through 9 that is connected with the channel l5.

The example illustrated in Figs. 4 and 5 is similar to that illustrated in the preceding figures except for the fact that the nozzle 24-25 moves with reference to the container 4 to be filled that assumes a stationary level, the stage illustrated being that corresponding to the filling of the container.

In Figs. 4 and 5, the same members have retained the same reference numbers as precedingly and the operation is as follows:

By reason of the rotary movement of the rotor 2 with reference to the stator I, the end of the pipe 2| connected with the opening 3i of said rotor has come into register with the channel l0 fed through the pipe 1, fed in its turn by the high pressure source that is not illustrated. Consequently the high pressure fluid passes through r -l n 3 li'l into Er e 'iiiifnk ii' eab ve the pis ton 20. T e latter; the i'fid 22 oftvhiehis new with the filling nozzle 'censjtrains saie ndz'zleto move into the egntaineij to be filled-and the closing member 28 carried by senescent: engages the neck of sai container.

But as the distributor fiir fluid unqefpressure is at this moment in the stage at Which it distributes high pressure fiuid the actieiri exerted by the upper part of 'the filling nozzle on the spring 21 overcomes the resistance of the latter so that'said spring 21 yields,- the feeding p pe 25 he longer (Emmet with the valve 26 and m aning eperatien may seem.

I p vided with a liquid I02 therein, such as beer, for example, and the space I03 above the liquid in the tank is filled with a gas under pressure, such as, for example, carbon dioxide. As is clear from Figs. 6 and '1, an elongated tube H5 has a top open end located in the space I03. This tube H5 is fixed at its bottom end to a member H6 covering an opening H1 in the bottom of tank I85 and formed with a bore IIB which is a continuation of and communicates with the tube H5. Member He has a bottom extension IE9 formed with radial bores 52%? communicating with the bore IE8. To. the bottom end of extension I I9 is fixed an elongated guide member lZI formed with one or more grooves I22 and carrying at its bottom end an enlargement W3. A tubular member Ii! has a lower portion slidably mounted on member I2I and an upper portion III" slidably engaging the extension H9, this member III being enlarged just below the upper portion III thereof to form a space it? located about the bores i20 and the top end of grooves 522, as is clearly evident from Fig. 5. The lower end of member III is formed with an enlargement It! adapted to engage enlargement I03 for closing the passage of gas from space N33 to the interior of bottle I0 3- through the tube H5, bore H8, bores I26, space I23, and grooves 522. When enlargement I87 of member Iii is spaced from member I08, as illustrated in Figs. 6 and 7, the interior of bottle I0 3 is in communication with space I63 through the above-described path. The upper end II! of member III is threadedly connected to member I2 5 which is mounted for sliding movement along member H63, and spring Iili engages at one end thereof member H8 and at the opposite end thereof a flange I2 3 of member I24 to urge the latter and n'ir-unber- I ll therewith toward enlargement IE3 so as to tend to maintain enlargement Iii? of member HI against enlargement I633 to prevent flow of gas from space W3.

A tubular member H0 is fixedly connected to a circular member 525 which is mounted for sliding movement along the lower end portion I25 of member I24, this member IEO forming between itself and member III an annular space communicating with the space I21 defined by members I2d, I25 and the portion of member I I i beneath the top end IIi thereof. This space I27 communicates through a bore I23, formed in member 42-1, and a bore iZii, formed in member I10, with the bottom of tank It! so that liquid I62 is free to fall through bores #29 and 523 and fill the space I27 and the annular space between members III! and Hi. A spring IE9, stronger than spring I06, bears at one end against member I25 and at an opposite end against flange I24 to urge the bottom end of member II?! against enlargement It! of member III, as shown in Fig. 6, to prevent liquid I32 from flowing from tank itl. Located about member I It is a sealing ring I05 adapted to engage the mouth of a bottle ISA which is to be filled.

The piston means 26 and the valve means and hydraulic circuit connected thereto are identical with the structure shown in Fig. 1.

When rotatably mounted valve member 2 is in the position where low pressure line I communicates with the piston 2d, the support 23 moves the bottle me against the sealing means I05 with a force great enough to overcome the force of spring I06 but not great enough to overcome the force of spring I09 so that enlargement I8! is thereby moved upwardly away from the enlargement I08 to the position shown in Fig. 6 so as to permit gas in space I03 to flow into bottle I 04, as described above, and wash any air out of the bottle. In this way the trapping of any air bubbles between the liquid which flows into the bottle and the sides of the bottle is avoided.

Upon continued rotation of valve member 2, the high pressure line 8 is placed in communication with piston 20 so as to move, with a force greater than that of spring I09, support 23 and bottle ii -4 thereon against the action of spring I09, thereby axially moving member IIII upwardly away from enlargement I01 to the posi tion shown in Fig. 7, so that liquid I02 may flow by gravity through bores I29 and I28, through space I2! and the annular space between members I IE3 and II I and into the bottle I04.

Upon further rotation of valve member I02, high pressure line 8 is cut off from piston 20 so that spring I09 then moves tubular member H0 back to the position shown in Fig. 6 where the flow of liquid I02 is cut ofi. The hydraulic fluid is then permitted to flow through discharge line 9 to permit support 23 to be lowered for the removal of bottle I04.

In the present description, the term fluid has been used for designating the medium used for transmitting difierent pressures and movements through the above mentioned distributor, said fluid may be constituted by compressed air or the like gas under pressure. It may also be constituted by a liquid such as oil for hydraulic movements, said latter arrangement being preferred.

Of course, the distributor considered may be of any type whatever such as a disc, cone, cylinder, valve or the like type, provided it allows the successive application of the diflerent pressures required for urging the neck of the container to be filled against the closing member carried by the filling nozzle, said different pressures being associated as disclosed hereinabove.

It is even possible to apply the different operative pressures otherwise than through a fluid under difierent pressures. However this latter solution is the most convenient chiefly in the case where the invention is applied to vacuum operated filling machines.

In this case, as a matter of fact, the distribution of fluid under difierent pressures, preferably under hydraulic control as disclosed, allows filling in any haphazard sequence containers even of varying heights without the duration and amplitude of the operative stage under low pressure being modified through said difierences. This is due on one hand to the fact that the closing of the filling channel is produced between application of high and of low pressure and is always provided by a relative movement of same amplitude whatever may be the height of the filled containers; on the other hand, the duration of the suction stage for the excess liquid or froth is also of constant amplitude whatever the height of the containers.
