UNITED STATES PATENT OFFICE 6 Claims. (oi. 226-68) My invention relates to improvements in hot tlefilling machines particularly adapted for filling bottles with beer, and to a method offilling bottles with beer.
It ha been found that air has a decidedly deteriorating efiect on beer and it has been found that where beer has been bottled and the content of air in the bottles is comparatively large, that after storage for a short period the bottled beer not only deteriorates as to color but as to the taste.
As a matter of fact, in the bottling of beer, if the air content of thebottle, after it has-been crowned, is greater than two per cent, thedeteriorating effect is decidedly noticeable.
It is one of the objects of my invention to provide a machine and method for filling bottles with beer and to fill the same in such a manner that the air content of the bottle after crowning is reduced to the In the apparatus andin the method in which I am able to fill the bottles, I am enabled to deliver filled and crowned bottles with approximatcly not more than four-tenths of one per cent of air. For the purpose of describing my invention, i have illustrated certain embodiments thereof in the accompanying drawings, in which:
l is an elevation of a' machine embodying my invention, part of the same being shown in of a machine embodying my invention, showing the path of travel of the bottles during the filling operation;
Figs. 3 and l are, together, a longitudinal sectional view of the initial gassing valve;
Fig. 5 is a longitudinal sectional viewoi the filler valve;
Figs. 6 and 7, taken together, constitute alongitudinal sectional view of the final gassing valve; and,
Fig. 8 is an enlarged sectional view of the bottle sealer.
For the purpose of more fully understanding the apparatus, it may be said that in carrying outmy invention initially the bottles to be ihled with beer are filled with CO2, delivered at a very low pressure, to the bottom of the bottle, and in a chilled condition. The bottles as they are received from the washing machine, having been rinsed in cold water, are in a chilled condition, and in order to maintain the density of the CO2 the CO2 is, as above stated, chilled to approximately the temperature of the bottles or to a temperature of approximately 40 F. The admission of the CO2 being heavier than the air, drives out the air and fills the bottle to the top with the C02. The bottle'is then transferred to the beer filling machine. In order to prevent any escape of the 002 during the transfer operation and to prevent the admission of air to the bottle, the bottle is sealed during this transfer period. The filling operation, naturally, drives out the CO2 in the bottle and supplants the same with beer. To allow for expansion of the liquid in the bottle, and for other reasons, the bottle is not filled clear to the top with beer but there is a small space in the neck of thebottle which is allowed to remain unfilled. In order to insure that no air shall penetrate to this space during the capping operation, before the bottle is delivered to the capper, the bottle goes through a final gassing operation which admits CO2 to the top of the bottle above the liquid contents, so that when the bottle is delivered to the crowner the bottle is completely filled with liquid and C02, preventing all possible chance or" the entry of air to the bottle. Furthermore, as the bottle is fed through the crowning machine, the crown is applied by a relatively slowly operating crowning, so that there is little chance of air being forced into the neck of the bottle by the rapid descent of the crown on the top of the bottle.
In the machine embodying my invention, illus trated in the drawings, I provide a base i, on which is mounted the various instrumentalities for carrying out by invention. On this base is mounted an initial gasser 2, asealer 3, a filling appaiatus 4, a final gasser 5, and a crowner B. These various instrumentalities' all continuously rotate in synchronism and means are provided for passing the bottle from one instrumentality to the other continuously. In each of the devices the various filling apparatus rot-ate with the bottle, so that the bottle continuously progressively moves through the machine.
Referring first to the initial gasses, a central standard 1 extends vertically from the base i, and on this central standard is rotatively mount ed a spider B, in which are reciprocably mounted bottle saddles 9. Each of these saddles is mounted upon the upper end of a reciprocating post 59, the lower end of which is provided with a roller H adapted to move over a stationarily mounted cam l2,-whereby, as the spider 8 rotates, the saddles will be vertically moved up and down.
The spider 8 is provided with a vertically-extending hollow sleeve l3, rotating with the spider andsurrounding the post I. The upper end of this sleeve is provided with a second spider M,
' the valve will reciprocate.
A supporting spider I9 is secured to the rotating spider l4 to support above the cam member I! a C02 reservoir 20, which therefore rotates with the gassing valves, and this reservoir is connected to each of the gassing valves by a flexible conduit 2|. The reservoir 20 is supplied with CO: from a suitable source through the supply pipe 22 which passes through a reducing valve 23 connected by a suitable swivel 24 with the reservoir. This reservoir 20 is surrounded by suitable refrigerating coils 25 enclosed in a casing 26 and receiving a suitable refrigerating medium from any source of supply, so that the temperature of the CO2 contained therein is maintained comparatively low and to coincide substantially with the temperature of the bottles as they. are received by the gasser from the washing machine.
Referring to Figs. 3 and 4, wherein I have illustrated a detail of one of the gassing valves IS, the gassing valve comprises a vertically reciprocating casing 21, reciprocably mounted in the tubular socket l5 of the spider l4 and keyed against rotative movement by a key 28. This casing is provided with a hollow bore 29, expanded at its lower end toprovide a valve chamber 30. The upper end of the casing is provided with a neck 3|, of reduced diameter, on which is screw-threaded a clamping screw 32' for clamping the valve end 33 of the supply tube 2| to the upper end of the casing and in communication with the bore 29. The roller I8 is preferably mounted on a collar 34 surrounding the reduced neck 3|.
Extending downwardly from the casing 21 is a filler tube 35, screw-threaded into a plug 36, in turn threaded into the lower end of the valve chamber 30; this plug being provided on its upper face with a valve seat 31. The lower end of the tube 35 has reciprocably mounted thereon a bottle bell or throat 38 containing a bottle engaging washer 39, and above this bottle engaging washer there is provided air vent openings 40. This bottle bell is retained against dropping off the lower end of the tube 35 by a. retaining nut 4| screw-threaded on the lower end of the tube 35 and engaging a shoulder 42 on the interior of the bell.
The passage of gas through ,the tube 35 is controlled by a sealing valve 43 at the upper end of the tube, which seats on seat 31 when closed. This valve is mounted on the upper end of a tubular stem 44 which extends to the bottom of the tube and at the lower end is provided with a manipulating tip 45 secured on the lower end of the stem and provided with gas passages 46, the arrangement being such that when the tube is inserted into a bottle this tip 45 will engage the bottom of the bottle, raising the valve 43 and permitting the passage of CO2 into the bottom of the bottle.
It will be noted that this stem 44 is hollow throughout and the valve .43 is provided with a conduit or passageway 41, so that the interior of the tubular stem communicates with the gas chamber 30 in the valve. The lower end of this stem is provided with an angularly disposed vent opening 48, so that, even though the valve 43 is in a closed position, there is provided a slight leakage of gas through the stem 44.
In the operation of the gassing valve as the bottle is received from the delivery mechanism toward the bottle, eventually engaging the bottle hell with the neck of the bottle, thus sealing the bottle, and projecting the tube 35 into the bottle until the tip 45 of the stem 44 engages the bottom of the bottle and a continued approach of the bottle to the valve Hi will cause this stem to raise the valve 43, admitting CO2 to the bottom of the bottle. This CO2 is admitted to the bottle at an extremely low pressure, say two or three pounds, and as it flows into the bottle fills the bottle, forcing the air out of the bottle, until by the time the bottle has moved to its delivery position it will have been completely filled with CO2 and the air exhausted therefrom. As the bottle and the valve I6 separate from one another, due to the riding down of the roller I l on the cam l2 and the riding up of the roller I8 on the cam H, the valve 43 is lowered on its seat 31, thereby shutting off further delivery of CO2 to the bottle. It must be borne in mind, however, that this movement is comparatively rapid, and the rapid withdrawal of the tube 35 from the bottle tends to create a slight vacuum or suction in the bottle, which would tend to draw back into the bottle through the vent openings a slight proportion of air. In order to break up this slight vacuum, even though the valve 43 is closed, there is a continued discharge of gas into the bottle-to be sure, a very small discharge-through the hollow stem 44 and through the diagonally-disposed vent opening 48 in the tip 45. I
By moving the gassing valve toward the bottle, during the time the bottle is moved toward the gassing valve, I am enabled to materially reduce the height of the cam lift of the bottle saddles 9. It must be understood that it is desirable to give the greatest possible time during the rotation of the bottle for the delivery of the CO2 thereto, and with an extremely high cam lift for the bottle a greater proportion of the circle of the cam is given to the cam proper and comparatively small portion is given to the straight run. By moving the valve toward the bottle and the bottle toward the valve, the cam lift is materially reduced, whereby a longer straight portion of the cam may be provided with a corresponding greater period during the rotation of the bottle in which the gas can be admitted to the bottle with no relative movement between the bottle and the valve.
After the bottle has been filled with CO2 it is delivered to the intermediate sealer 3. This sealer is provided with a base portion 49 carrying a vertical post 50 rotatively stationary, and surrounding this post and rotating on the same is a bottle carrier 5| which extends through the table top 52 and is provided with a pair of bottle transfer stars 53 adapted during their rotation to engage the bottle while on its saddle 9, and while the saddle is in its lower position, and rotate the bottle to a position to be delivered to the filler 4. Mounted on the bottle carrier and above the bottle sealers 56.
stars 53 is a plurality of vertically disposed bear.- ings 54 adapted to receive the stems 55 of the ciprocable to be moved down into sealing engagement withrthe top of the bottle as it is received on the carrier 52, and the stems of the sealers are provided with rollers 51 operating in a cam 58 stationarily mounted on the post 58 and provided with a cam track so disposed as to lower the sealer 56 on a bottle as it is received from the bottle saddle 9 and maintain the bottle sealed until it is delivered from the sealer to the filler, at which time the cam will raise the sealer from engagement with the bottle to permit this delivery to the filler. The sealers are adapted to swing in and out during their vertical movement so that they will clear the bottles of the initial gassing machine. To this end, each sealer is mounted on a cross arm mounted to swing on a vertical axis on the top of its supporting stem 55. One end of the cross arm carries the sealer 56 and the opposite end is bent slightly downwardly and carries at its end a roller 68 which engages a cam surface 6|, being biased in an engaging direction by suitable spring means (not shown). As the stem 59 is lowered, the roller 55 moving to the smaller portion of the cam surface, will permit the sealer to swing, on a vertical axis, out from the center of the circle and in a position to engage on the top of the neck of the bottle. These sealers preferably comprise cuplike members provided with sealing washers 62.
The sealer, in effect, comprises a transfer mechanism for removing the bottle from initial gasser and delivering the same to the filler, acting, at the same time, to seal the bottle during this transfer. As the bottle rotates with the sealer it eventually comes into a position to be delivered by the stars 53 thereof to one of the saddles 63 of the filling machine. This filling machine, to a large extent, is more or less standard, and it is not believed necessary to enter into a full detailed description thereof, except so much of the same as is necessary for the understanding of the present invention. The filler is provided with a rotating support 64 provided with a plurality of reciprocating bottle saddles 63, which saddles are mounted on reciprocating supports 85, vertically moved through the instrumentality of the cam-operated arms 66. This support carries the usual water check tank and high pressure cylinder 61 into which is admitted through the pipe 68 water and through the gas swivel valve 69, CO2 under pressure. It must be borne in mind that the water which is admitted is not admitted continuously, but the pipe 68 is merely a supply pipe and when the proper supply level of water is obtained in the tank the supply is cut off.
This support 54 also carries an annular filler tank 18 to which the beer is admitted through the supply pipes H connected with a pressure con-, trol valve 12 in turn connected with the supply.
Tothe filler tank are attached a plurality of filling valves 15, each of which connectsto' the high pressure tank cylinder 13 in the water check tank 61 through the medium of a communicating pipe 14.
Each filler valve comprises a filler tube 88 communicating with the interior of its tank 18 and supported in a casting l6 forming'a portionof the bottom of its filler tank 78.- This casting is provided with'a neck 8! into which the tube 88 is screwed and also is provided with a neck 82 to which is attached by a coupling nut 83 a counter- These bottle sealers are repressure valve casing 84. A pair of pressure tubes 11, extending upwardly from the casting, have communication with the chamber 79 in which is arranged the counter pressure valve 81 adapted to seat on the seat 86. The upper ends of these two tubes communicate with a chamber having arranged therein a diaphragm 93. Arranged at the lower end of the neck 82 is a sealing washer 85. The valve 81 surrounds the filler tube 88 and is provided with a tubular neck 88 surrounding the tube and projecting below the sealing washer 85. The valve is biased in its closed position by'a coiled spring 89 and the neck 88 is provided with bleeding openings 98, for a purpose more fully hereinafter to appear.
The bottom of the filler tube 88 is closed by a pear valve'9l, downwardly opening, and secured to the end of a stem 92 the upper end of which is connected to the diaphragm 93. The normal position of the diaphragm'is such as to maintain the valve 9i in its closed position. Also mounted on the filler tube 88 is a bottle bell or throat 94 provided with a sealing washer 95 and surrounding the tube. The top of this bell, when the tube is inserted in a bottle the proper distance, is adapted to engage the bottom end of the neck 88 to thereby raise or open the counter pressure valve 81. The counter-pressure chamber or compartment 19 is connectedv through a ported stem 96. and a conduit 91 with the top of the gas and water tank 61, in which C0: is maintained under pressure, varying from eight to twenty-two pounds, depending upon the nature of the beer to be bottled, which, however, is slightly lower than the head of the beer in each of the filler tanks l8.v
In addition to the above supply of CO2 the-bottle bell 94 above the sealing Washer 95 is provided with a gas chamber 98 connected by a flexible tube 99 with a ring l88. This ring in turn is connected by a conduit l8! through a gas swivel valve I82 with a C02 inlet pipe I 83, connected with a C02 supply, and delivering CO2 at a decidedly reduced pressure as compared with the pressure delivered through the tube 91. In commercial use I have found that the pressure delivered through this tube should be only about three pounds. The end of the tube 99 is provided with what is commercially known as a Thomas v check valve 684, which in eifect constitutes a soft rubber nozzle having an opening through which the gas under the pressure of three pounds may pass; but with a back pressure introduced in a chamber I85 surrounding this Thomas valve exceeding the three-pounds opening pressure, the
' valve would be closed to prevent back flow.
In operation, when the bottle is first lifted, it engages the bottle bell 94, the neck of the bottle being sealed by a sealing ring or washer 95. Thebell raises with the bottle until the top of the bell engages the neck 88 of the counterpressure valve, raising the counter-pressure valve off its seat. This admits counter-pressure into the tubes ll-ll, which, flowing through the neck 98, and through the bell 94, flows into the bottle to establish counter-pressure therein. When the counter-pressure in the bottle has been built up it continues to build up above the diaphragm 93 to open the valve 9 I, permitting the flow of beer into' the bottle against the counter-pressure of the gas. The counter-pressure of the gas is slightly below the head of the beer in the filler tank, so that this beer will flow therein. By the time the bottle has been filled to the point desired, the
bottle will commence to move downwardly first closing the counter-pressure valve 81. This shuts off the counter-pressure supply and the bleeding of the CO2 from the compartment I9 through the bleeding openings will so reduce the pressure in the compartment and against the diaphragm 93 that the valve 9| will close, shuttingofi the flow of 'beer through the filler tube. As long as the counter-pressure valve is open and the counter-pressure gas is admitted through the bottle bell and into the chamber 98, this pressure will be greater than the pressure in the pipe 99, and thereby maintain the Thomas valve I04 closed to prevent the back flow of the counter-pressure through this valve and into the pipe 99. When the bottle bell is lowered and breaks contact with the bottom of' the neck 88 this back pressure no longer exists and the two or three pounds pressure of gas in the pipe 99 is sufficient to open the Thomas valve I04 and flood the bell with gas. If this bell top were not so flooded with gas there would be an appreciable quantity of air sucked into the bell top, due to the suction created by the removal of the tube from the bottle, and this air would pass down into the bottle proper. However, by flooding the bell top with CO2, any air which might have been trapped in there is driven out, and the entry of any air is prevented, thus insuring the freedom of the neck of the bottle from air.
The bottle thus filled in the filling machine thentransfers tothefinal gassing apparatus. This gassing structure is substantially the same as the initial gassing structure, with the exception that the bottles are carried on the table 52 instead of on reciprocating saddles 9. This table surrounds a sleeve I01 surrounding and rotatively mounted on a vertical post I08. The vertical post carries sleeve I01, and carries the spider having formed at the outer portionthereof a plurality of tubular sockets I09 for the reception of the final gassing valves H0. The post I08 carries the cam III which cooperates with the rollers H2 on the valves for raising and lowering the valves. In view of the fact that the delivery tube of the sealing valve does not have to enter the bottle very far, the relative reciprocatory movement between the valve and the bottle does not have to be as great, and therefore the vertical movement of the bottle itself is dispensed with. The sleeve has mounted or formed thereon a pair of bottle carrying stars H3 which receive the bottle from its saddle 63 of the filling machine, and moves them on the table to beneath the final gassing valves. As shown, each of these gassing valves is connected by a tube I I4 with a gas reservoir H5, supplied like the reservoir 20 with C02.
The reciprocating gassing valve casing H5 is substantially the same in construction as the gassing valve casing 21, being provided with a chamber H9 closed by a plug I I! having on its upper face a valve seat H8. The gassing valve tube H9 extends through the plug II I, being provided at its upper end with inlet ports I20 with a valve I2I adapted to seat on the valve seat H8; and it will be noted that when the valve I2I is seated, no communication exists between the chamber H6 and the filler tube. The lower end of the tube H9 is provided with a tip IE2 provided with horizontally disposed delivery openings I23 connecting with the tube, so that CO2 delivered at the lower end of the tube will be delivered horizontally against the side of the bottle, and thereby not tend to agitate the liquid in the bottle. Surrounding the gassing tube H9 is a bottle bell I24 provided with the usual sealing washer I25 and provided above the sealing washer with vent openings I26. This bell has an upwardly extending neck I2'I externally screwthreaded to receive an adjustable stop member, I28, adapted when the bell is raised to the limit of its upward movement by. engagement with the bottle, to engage the shoulder I29 on the tube H9 and raise the valve I2I off its seat. It is therefore obvious that as the final gassing valve is lowered the gassing tube H9 will be projected into the neck of the bottle, stopping. just short of the liquid level, and at the same time the bottle bell will be raised sufficiently to open the valve I2 I, admitting CO2 under very low pressure to the neck of the bottle, and thereby forcing out any air which might have collected in the neck, up through the bell and through the escape openings I26, and displacing this air with CO2.
After the final gassing, the bottles are engaged by transfer stars I30 which remove the same from the final gassing apparatus and deliver the same to the underlying stars I3I on the crowner 6. This crowner is a well known commercial structure, and it is not believed that a detailed description thereof is necessary except to say that the crowner is preferably of the eight-head type for a filling machine delivering bottles at the rate of per minute or more. The crowner head carrying member I32 is provided with reciprocating crowning heads I33 which are rotated on the standard I34 carrying the stars I3I and descend upon the bottle, crowning and sealing the bottle. I mention the fact that I preferably use an eighthead crowner fora filling machine operating at the rate of 120 bottles per minute, as I have discovered that it is advisable and desirable to have the crowning head approach the bottle at a comparatively slow speed. If the crowning head drops upon the bottle at high speed,-the rapid descent of the crown has a tendency to force a percentage of air into the bottle, but I have found that where the crowning head reciprocates at approximately only fifteen times per minute, as
.tles are delivered through the guide-way I36.
The initial gasser rotates in a clockwise direction and ultimately delivers the bottles to the sealer, the stars 53 of which are disposed between the initial gasser and the filling machine. This sealer rotates in a counter-clockwise direction, the bottles being maintained in their position by a guide I31, and ultimately delivers the bottles to the saddles 63 of the filler 4. The filler rotates in a clockwise direction, and the filling process takes place Where it is received from the stars 53, until it is delivered upon a delivery disk I38, which rotates in a clockwise direction and tends to move the bottles through the guide-ways I39 into a position to be engaged by the stars I I3 of the final gasser 5. The final gasser 5 rotates in a counterclockwise dlrection, and the bottles, after final gassing, are eventually picked off the final gasser by a transfer star I30, and delivers the same to the stars I3I of the crowner 6, suitable guideways I being provided for the bottles. After the crowning operation, it being noted that the crowner rotates in a counter-clockwise direction, the bottles are eventually picked off the crowner by the delivery stars I42 and transferred to a suitable conveyor or other apparatus.
The spider 64 of the filling machine is driven through any suitable power apparatus, as by an electricfmotor, or the like, and the remaining 1 apparatus, including the gassers, the sealer and the crowner, are intergeared so that the parts of the various devices will operate in unison. I have shown a master'gear M3 on the spider 64 which throughsuitable intergears is adapted to drive gears onthe gassers, sealers and other parts. These are not illustrated, as it is believed that it would tend toward confusion of the parts, while it is believed'that understanding of the operation can be obtained without illustrating these detailed parts.
