7 Claims. 1

The present invention relates to a machine for filling liquids into containers or cans and has particular reference to improvements in the filling devices.

In the filling of some liquids, such as milk, fruit juices, brines, syrups, canning liquids, carbonated beverages or thelike into'containers, the agitation of the. liquid results in the formation of considerable foam which afi'ects the accuracy of: the ultimate weight or volume of the contents of the container. To offset this tendency of foaming numerous attempts have been made to introduce the liquid into the container in a manner which causes the liquid to engage the interior walls of the container and thereby flow gently along the walls and gradually build up from the container bottom. This manner of filling containers has been satisfactory in a great many cases.

However in order to fill containers in this manner a nozzle isprovided which usually must be inserted into the container so that the liquid can be readily projectedagainst the interior wall of the container. In manytypes of filling machines this insertable nozzle is impractical.

The instant invention contemplates overcoming this difficulty by the provision of an improved liquid filling nozzle which is noninsertable or need not be inserted into a. container and which. is disposed in an angular position for introducing liquid into the container without creating appreciable foam. The. invention further contemplatesa novel nondrip type of filling nozzle and an improved no-container-no.fill device which is particularly adapted to an inclined type nozzle.

An object, therefore of the present invention is the provision in a liquid filling. machine of improved filling devices wherein the filling nozzle is disposed in an inclined position relative to a container to be filled so that a stream of liquid may be directed from the nozzle through a filling opening in the container and projected against an interior wall thereof without inserting the nozzle into the container, for gently filling the container with the liquid. while minimizing the formation of foam.

Another object is the provision ofsuch improved filling devices wherein all liquid, at the termination of a container filling operation, is forced out of the nozzle outlet to avoid dripping of the liquid on the top of the container adjacent its fillingpopening while the container remains. under the nozzle or is being removed from filling position.

Another object is the provision in such a filling machine of improved nozzle actuating devices which are particularly adapted for use with an inclined nozzle and wherein continued operation of the nozzle or a plurality of such nozzles may be had as long. as the containers are properly placed in filling position under the nozzle or nozzles, the actuating. devices being rendered inoperable when no container is in place, so that the particular nozzle will remain closed with the result that. waste of the liquid and contamination of the machine will be prevented.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

As a preferred and exemplary embodiment of the instant invention the drawings illustrate a liquid filling machine for fillin milk or other -foam. producing liquids into square fibre empty containers A having a circular filling and dispensing opening B in their top end, such as the container disclosed in United States Patent 2,085,979 issued. July 6, 1937 to John M. Hothersall on Container, although the invention is equally well adapted to filling other containers also.

The empty containers A to be filled are fed into the machine in an upright position and in a substantially continuous procession, preferably by an intermittently rotated feed turret 2i comprising a pair of vertically spaced and parallel turret wheels (Figs. 1 and 2) having spaced D ripheral pockets 22 which engage and advance the containers in spaced and timed order. The containers are supported on a curved table 23 and they are retained in the turret pockets by inner and outer guide rails 24, 25 disposed adjacent the periphery of the turret. The turret is mounted on the upper end of a vertical shaft 26 journaled in a bearing 21 (Fig. 2) formed in a frame 23 which constitutes the main frame of the machine. The shaft may be rotated intermittently in any suitable manner.

A container A advanced by the feed turret 2i is transferred, for the filling operation, to a filling turret 32 having a plurality of pockets 33 spaced around its outer periphery for the reception of the containers. The filling turret 32 is mounted on a vertical drive shaft 34 journaled in a bearing (Fig. 2) formed in the machine frame 2%. The shaft 3 is rotated preferably intermittently, in any suitable manner in time with the feed turret shaft 2% so that the feed turret pockets 22 move into register consecutively with the filling turret pockets 33 as the two turrets rotate.

Transfer of the containers A from the feed turret pockets 7.22 to the filling turret pockets 33 is effected preferably by the inner guide rail 2 which at the point of transfer curves outwardlt toward the outer periphery of the feed turret and thus pushes the containers out of the pockets 22 into the pockets 33 as the pockets move into register. A guide rail 36 forming a continuation of the guide rail 2d curves around the outer periphery of the fillin turret 32 and holds the containers in their pockets.

As a container A moves into a pocket 33 of the filling turret 32 it is received on a lifter pad 38 (Figs. 2 and '7). The pad 38 is formed on one end of a lifter lever 39 mounted on a pivot pin secured in the fillin turret 32. There is one of these lifter levers 39 for each turret pocket 33 and they are disposed below the pockets. Each lifter lever 39 carries an actuating roller ll which operates against a stationary cam rail 42 disposed adjacent and extending around the outer periphery of the filling turret 32. A tension spring 43 keeps the roller in engagement with the cam rail. One end of the spring is connected to a lug it formed on the filling turret while the op posite end of the spring is secured to an arm 45 formed on the lifter lever 35.

The cam rail 42 is shaped so as to hold the lifter lever 39 and its lifter pad 38 in a depressed position while the container is being transferred into the filling turret pocket 33 and then as soon as the container is in position, to permit the spring 33 to raise the lifter pad and the container. This lifting of the container raises it and clamps or looks it in place against a clamping or locking lug iil (Figs. 1 and 2) which projects out from the filling turret 32 above its pocket 4 and which engages the container at its upper edge as best shown in Fig. 2. There is one of these locking lugs $8 for each turret pocket 33.

A container A received and clamped in a filling turret pocket 32 is located with its filling opening B in proper position for filling of the container. This filling is effected with a measured charge of the liquid taken from a reservoir Ell (Figs. 1 and 2) which is mounted on top of and rotates with the filling turret 32. For this purpose each pocket 33 of the filling turret 32 is equipped with an adjacently located filling device 52 and a connecting measuring device 53.

Each filling device 52 includes a tubular housing as (Figs. 2, 4i, 5, 8 and 9) which is located between the reservoir 5i and the filling turret 32 and which is disposed in a radial position and at an angle sloping downwardly and outwardly from the reservoir toward its associated filling turret pocket. The housing 5 1 is formed with an interior longitudinal tubular passageway 55. Near its upper end the housing is formed with a tubular upright conduit 5&5 which is secured to the bottom of the reservoir 5! and which provides communication between the reservoir and the passageway 55 in the housing.

The lower end of the housing M (Fig, 5) terminates in a nozzle 5? having an angular outer face which is substantially flush with the lower face of the container locking lug t8 so that the face of the nozzle will be closely adjacent but not quite touching the horizontal top of a container A clamped in position for filling as best shown in Fig. 2. This nozzle end of the housin is formed with a long reduced diameter outlet 58 which at its inner end communicates with and is concentric with and in axial alignment with the passagewayfiii and which at its outer end is disposed so that it will substantially align with the filling opening B in the positioned container for filling the liquid into the container.

A cylindrical slide valve 66 is slideably disposed within the passageway 55 of the housing 5% and is slightly smaller in diameter than the passageway to facilitate easy sliding movement. The lower end of the valve is formed with a plunger 62 which is slightly smaller in diameter than the nozzle outlet 58 and which terminates in an angular face 63 which is similar to the angular face of the nozzle 5'! for cutting off the flow of liquid from the nozzle without dripping as will be hereinafter explained.

lhe slide valve Bl at its upper end is formed with a long small diameter stem 55 which terminates in a guide block 56 slightly smaller in diameter than the passageway 55 to seal the upper open end of the passageway, to facilitate sliding movement therein and also to serve as a guide for the valve 61. This guide block 65 is secured to an actuating sleeve 58 (see also Figs. 8 and 9) which surrounds the outside walls of the upper portion of the housing 5 The sleeve is formed on a flat slide as (see also Fig. 10) which is disposed exteriorly of the housing and hi h operates in a slideway It formed on the housing in parallel relation to the housing passageway 55. The slide is actuated by a roller ll which is carried on the slide and which is operated as will be hereinafter explained to control the flow of liquid from the reservoir 5!. The slide valve 6i also controls the fiow of liquid into the measuring device 53.

The measuring device 53 for each filling turret pocket 33 includes a vertically disposed round measuring sleeve l2 (Fig. 2) which defines a measuring chamber 13 open at its upper and lower ends. This sleeve is secured in an opening 14 in the filling turret 32 adjacent the pocket 33. The upper end of the sleeve extends up into a cap 15 formed as an integral part of the filling housing 54. This cap defines the upper end of the measuring chamber 13 and is formed with a channel I6 which provides communication between the measuring chamber 73 and the filling housing passageway 55, the channel entering the passageway between the conduit 56 and the nozzle outlet 58 as best shown in Fig. 2.

The measuring chamber 13 houses a vertically movable piston I8 the top of which defines the lower end of the measuring chamber l3. This piston is pivotally connected by a piston rod I9 to a slide block 89 which operates in a vertical slideway 8| formed in a lower skirt portion of the filling turret 32 (see also Fig. 12). The slide block carries a cam roller 82 which operates in a stationary cam track 83 secured to the machine frame 28 and encircling the skirt portion of the filling turret 32. The track is shaped to lift and lower the piston 13 as the cam roller traverses the track with the rotation of the filling turret 32. This measuring device is in a conventional device similar to that disclosed in United States patent 1,506,851 issued September 2, 1924, to T. Martin et al. on Filling Machine.

In the operation of the machine through a filling cycle, a filling turret pocket 33 moves into container receiving position upon a partial rotation of the turret 32, with the measuring device piston 18 in a lowered position in the lower end of the measuring sleeve 12 and with the valve plunger 62 disposed in and closing the nozzle outlet 58 as shown in Fig. 2. In this position of the piston and the plunger, the slide valve is! is disposed in but does not close the channel It the measuring chamber I3 and thus there is no obstruction between the reservoir and the measuring chamber I3. Therefore the liquid flows freely from the reservoir til, through the conduit 56, connecting passageway 55 and channel 16 into and fills the measuring chamber 73, the liquid within the measuring chamber 13 and the channel It constituting ameasured charge to be filled into a container A.

The measured charge of liquid can be filled into a container only by the opening or lifting of the valve plunger 62 and this is effected only upon condition that a container A is in position in its filling turret pocket 23 to receive the charge of liquid. For this purpose there is provided an improved container detecting and valve opening device IBI (Figs. 1, 2, 3 and 5) which includes a cam lever I02 mounted on a pivot pin I 63 carried in a stationary bracket IE4 secured to a column I65 of the machine frame 28. The cam lever Hi2 carries a cam roller I035 which operates in a cam groove I61 of a continuously rotating barrel cam I08 mounted on a vertical shaft I139 journals-d in a bearing Ho formed integrally with the column I 65. The shaft may be rotated in any suitable manner in time with the other parts of the machine so that the cam makes one revolution for each partial rotation of the intermittently rotated filling turret 32.

The cam I68, through the cam lever I02, actuates a rocker lever H4 which intermediate its ends is mounted on the pivot pin I03. One end of the rocker lever I I4 extends alongside the cam lever I02 and is yieldably connected thereto by a flexible connection. This flexible connection includes an eye bolt 6' which is pivotally connected to the adjacent end of the rocker lever I I4 and which extends up through an opening in a laterally projecting lug I I! of the cam lever I02. Between the lug II! and the end of the bolt I I6, a compression spring H8 surrounds the bolt and is held in place by a washer and a lock nut H9.

The outer end of the rocker lever I I 4 is pivotally connected to a depending link [2L The lower end of the link I2! is pivotally connected to a rockable, valve actuating member I22 which is disposed adjacent the place where the containers A enter the filling turret pockets 33 and which is secured to a short rocker shaft I23 (Figs. 3 and 5) rotatably carried in a pair of spaced bearings I24 formed on a stationary bracket I25 bolted to the machine frame 28. Between the spacedbearings I24, the rocker shaft I23 carries a valve opening shoe I28 which moves with the rocker shaft and the actuating member !22.

The valve opening shoe I28 normally extends adjacent and slightly below the circular path of travel of the valve actuating rollers II of the filling devices 52 as the latter are carried around with the rotation of the filling turret 32. The shoe I28, however, is movable through an upwardly extending are a it moves with the rocker shaft I23, to engage under and lift the actuating rollers H to open the slide valves of the filling devices. The shoe is so located that its forward end is adjacent the actuating roller II of its associated filling device when the filling turret 32 is at rest between its intermittent rotations and a filling turret pocket 33 and its associated filling device is in position to receive a container A to be filled, as best shown in Figs. 1 and 2.

As a container A is being transferred from the feed turret 2| to the properly located filling turret pocket 33', the barrel cam I08 through its cam lever I02 and rocker lever I I4, is just starting a rocking movement of the valve actuating member I22 and the shoe I23 begins its upward arouate travel. During this upward travel of the shoe I28 it engages under and lifts the actuating roller ll and this raises the valve slide of the filling device. By the time the container is fully seated in its filling turret pocket, the slide valve has moved up into the position shown in Fig. 4 where the plunger 62 is still in the nozzle outlet 58 and holding it closed, and where the valve 6i has moved up far enough in the passageway 55 of the filling housing 54 to block off communication between the reservoir 5I and the measuring chamber 13. This action segregates the measured charge of liquid in the measuring chamber from the liquid in the reservoir.

As the shoe I28 continues to lift the roller II, it withdraws the plunger 62 from the nozzle outlet 58 and thereby opens the outlet for the delivery of the liquid into the container. This position of the slide valve is shown in Fig. 5, the shoe I26 being at the top of its stroke. As soon as the shoe has reached this position, the filling turret 32 advances one step through a partial rotation of the turret and during this advancement and while the shoe is holding the slide valve open, the roller II travels along the shoe and rides off its farthest end onto a stationary holding rail I3I (Figs. 1, 2 and 5). This holding rail I3I extends partially around the outer periphery of the filling turret and is supported on brackets I32 which are secured to the machine frame. The rail holds the slide valve open While the filling turret moves through it partial rotations.

During these partial rotations of the filling turret 32, the measuring chamber. piston 78, op-

crating under the action of the stationary cam 83, moves up in the measuring chamber 13 and forces the measured charge of liquid from the chamber, through the channel It and open nozzle outlet 58, into the container. The nozzle being at an angle to the container, directs the stream of liquid through the opening B in the container and projects it against the interior side wall of the container as hereinbefore explained.

Near the end of the cycle of operation of the filling turret 32, when all of the liquid has been forced out of the measuring chamber by the piston I8 reaching the top of its stroke, as shown in dot and dash lines in Fig. 2, the slide valve is closed and the piston returns to its lowered original position. Closing of the slide valve is effected by a stationary closing cam I35 (Figs. 1 and 11) which is disposed adjacent the terminal end of the holding rail I3! and which forms a continuation of this rail. The cam is supported on a bracket I36 secured to the machine frame 23.

Hence when a roller II of the filling devices 52 reaches the terminal end of the holding rail l3! it rides off the rail and into the cam I35 as shown best in Fig. 11. This cam is formed with a downwardly curved cam groove I31 which forces the roller II downwardly into it original position. This lowering of the roller shifts the slide valve downwardly, moving the plunger 62 down into and closing the nozzle outlet 58 and also moves the valve 65 down into position adjacent the channel 76 of the measuring chamber. This action permits the measuring chamber E3 to be refilled with liquid from the reservoir 5! for a subsequent container A.

The plunger $2 in moving down through the nozzle outlet 53 continues to move until its outer angularly disposed face 63 is at least flush with the outer angular face of the nozzle 51 and preferably projects slightly beyond the nozzle face. During this travel of the plunger 62 it forces any residual liquid completely out of the outlet to a point beyond the outer angular face of the nozzle and thereby leaves nothing to subsequently drip from the nozzle. The plunger remains in this position until opened for a subsequent container so as to insure against uncovering any internal surface of the nozzle and thereby prevents any dripping of liquid.

After closing of the slide valve of the filling device, the filled container A is engaged in a pocket I (Fig. l) of a discharge turret I42 disposed adjacent the filling turret 32. This turret I42 is mounted on a vertical shaft I43 journaled in a suitable bearing formed in the machine frame 28. The shaft is rotated intermittently in any suitable manner in time with the filling turret 32 so as to effect proper register of the pockets of the two turrets for the transfer of the filled containers from one to the other.

A guide rail M5 d sposed adjacent the outer periphery of the discharge turret I42 engages the containers while still in the filling turret pockets 33 and effects the transfer of the containers and holds them in place in the discharge turret pockets MI. The containers rest on a curved table it? disposed adjacent the discharge turret and are propelled along this table by the turret to any suitable place of deposit. This completes a filling cycle of the machine.

As hereinbefore mentioned, provision is made for preventing the opening of the slide valve in case no container is advanced into place in a filling turret pocket 33 to receive the charge of liquid which is measured out in the measuring chamber I3. For this purpose the valve opening device III] is provided with a container detector finger l5! (Figs. 1, 2 and 3) which is disposed in a substantially horizontal position and which is mounted on a pivot shaft i52 carried in a depending lug I53 of the bracket I225. The outer end of the finger is formed with a detector plate E55 having tapered edges which project into the path of travel of the containers A as the latter are being delivered from the feed turret 2i to the filling turret 32.

The inner end of the detector finger I5l, adjacent the pivot shaft I52, is formed with a substantially upright locking finger I56 which terminates adjacent a stop lug I5? formed on the valve actuating member I22. The stop lug I51 moves vertically with the valve actuating member I22. During this movement of the actuating member the locking finger I56 is normally held out of the path of travel of the stop lug I57 by a roller I58 which is carried on a depending arm I59 of the actuating member I22. The roller normally engages against a sloping cam face I6! on the locking finger I56 as best shown in Fig. 2. A spring I62 keeps the locking finger against the roller. One end of the spring is secured to the finger while the opposite end is pinned to the lug I53. A stationary stop screw I6 1 adjustably secured in a boss E55 of the lug I53 is provided to limit the travel of the locking finger I56 under the tension of the spring I62.

Under normal operation of the machine as when containers follow each other in properly spaced and timed order, the containers pass under the detector plate I55 and lift it, with the result that the locking linger I55 is rocked outwardly away from the path of travel of the stop lug I5! as the latter moves down with the actuating member I22. It is this action that permits lifting and opening of the slide valve as explained above.

When no container is advanced by the feed turret 22 for transfer into the filling turret 32, the detector plate I55 remains unsupported. Hence, when the actuating member i222 moves down, the roller We on the arm 59 rides along the cam face Isl of the locking finger I56 and permits the tension spring IE2 to draw the looking finger I56 inwardly under the stop lug I5! until the locking finger engages the stop screw 6%. "With the locking finger thus disposed in the path of travel of the stop lug ii, the actuating member 522 can move down until the stop lug engages the upper end of the locking finger as best shown in Fig. 6. The locking finger then arrests further downward movement of the actuating member 122 and the excess movement supplied by the cam I08 is taken up by compression of the spring I58 of the flexible connection between the levers Iil2, I I4 (see Fig. 3). The movement of the actuating member I22 required to effect this locking operation is insufficient to raise the roller ii on the filling devices 52. Hence the slide valve remains unopened.

During subsequent partial rotations of the filling turret 32, the filling device roller II passes under the holding rail Hit, the rail serving as a stop to prevent inadvertent opening of the slide valve during rotation of the filling turret. The locking of the slide valve in closed position, maintains the communication between the reservoir El and the measuring chamber 73. Hence the measured charge of liquid in the chamber is returned to the reservoir as the measuring piston 18 moves up through its regular cycle of operation, the liquid returning to the measuring chamher for a subsequent contain-er, as the piston moves down to its original position.

Since the actuating member E22 moves through a down or valve actuating stroke and thence up through a return stroke for each partial rotation of the filling turret 32 and the feeding turret 2!, the return stroke of the member moves the arm 159 and its cam roller I53 outwardly against the locking finger E56 and thus forces the finger outwardly to raise the detecting plate i535 to a posi' tion Where it maybe properly engaged by the next advancing container. If a is in place in the line to be transferred to the filling turret, it engages and lifts the detector plate as explained above to permit filling of the eontainer, otherwise the actuating member 522 is again locked against opening the slide valve explained above.

It is thought that the invention and many of its attendant advantages will be unders toot-i from the foregoing description, and it will be apparent that various changes may be made in he form, construction and arrangement of the without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

In a machin for filling liquids into containers, the combination of a rotatable filling turret having pockets for receiving containers to be filled, means for feeding containers in spaced and timed order into said pockets, a reservoir rotatable with said filling turret for holding a supply of liquid, a valve housing connecting with and providing communication with said reservoir, said housing having a nozzle with an outlet disposed adjacent said turret pocket and located at an angle thereto for projecting a stream of liquid into said container against a side wall thereof at an angle thereto to minimize foaming of said liquid, a slide valve disposed within said housing and having a plunger movable into and out of said nozzle outlet for controlling th-e flow of liquid into said container, a movable lifter shoe disposed adjacent said turret and engageable with said slide valve for with drawing said plunger from said outlet, actuating means for said shoe, a holding rail disposed adjacent the periphery of said turret and extending partially therearound for receiving said shifted slide valve from said shoe and for retaining said valve in its open position as th turret rotates to continue the filling of said container, and cam means disposed adjacent the terminal end of said holding rail for shifting said slide valve to close said nozzle outlet with said plunger.

'7. In a machine for filling liquids into containers, the combination of means for supporting an upright container to be filled, a reservoir for holding a supply of filling liquid, a liquid measuring device below said reservoir, a tubular housing located between said reservoir and measuring device with the lower end of the housing directed toward the top of the container and the axis of the housing disposed at an acute angle thereto, said housing having a nozzle outlet formed at its lower end for directing fluid angularly into the container and a passageway formed in the upper portion of the housing and extending longitudinally from said outlet through the upper end of the housing, said passageway at an upper portion communicating through a lateral supply opening with said reservoir and at a lower portion communicating through a channel with said measuring device, a valve within said passageway and movable therein to control the flow of liquid through said passageway between said supply opening and said channel, a plunger on the lower end of said valve and movable into said nozzle outlet for controlling the flow or liquid therethrough, a block slideable and closely fitted in the upper end of said passageway and connected by a stem to said valve, said lock thus serving as a guide for said valve and as a liquid seal for the upper end of said passageway, and means for moving said integrated plunger, valve and block in one direction to close said outlet and to permit liquid to flow from the reservoir to the measuring device, and to move them in the opposite direction to stop the fiow from the reservoir and to permit the liquid to flow from the measuring device through said outlet and angularly into said container.
