MIL, assignors to Crown Qork & Seal Company, Inc., Baltimore, Md., a corporation of New York Application September 29, 1937, Serial No. 166,403 I i 4 Claims. (01. 226-75) I The'present invention relates to filling ma chines oi the type for filling bottles or other containers with liquids such as carbonated beverages.

The invention particularly relates to filling machines or high production capacity, such as usually comprise a stationary table and a rotary filling table adjacent the same, the stationary table being provided with a syruping mechanism and a crowning mechanism. In such machines, suitable means must also be provided on the stationary table to move containers from the syruping mechanism to the rotary filling table, and also to remove filled containers from the latter to positio them'beneath the crowning mechanism.

It is highly desirable that all of the mechanisms for handling the containers be 50 arranged and designed that the container will be smoothly moved through the machine, that is, with no Jarring or vibration of the containers such as would result in-breakage oi the containers, or disturbance of their contents.

The principal object of the present invention fact that filled and uncapped containers have their direction of travel sharply changed at the time that they are removed from the filling table is also a serious defect of single transfer dial fillis to provide a filling machine wherein all of the container handling elements. including the elements for periormingan operation upon the container, are so'arranged that jarring oi the containers will be eliminated,'and the path oi! travel of the container will at no time be sharply changed.

Filling machines-of previous designs including rotatably movable syruping and crowning mechanisms have been provided with asingle dial for moving containers such as bottles from the syruping mechanlsmto the filling table and for subsequently removing containers from the filling table to the crowning mechanism. The use of a single dial for accomplishing these movements of the container is unsatisfactory because oi the fact that it results in a sharp change oi direction of travel of the container at the moment that the container is positioned upon the filling table, and also at the moment that the container is removed from the filling table. This sharp change of direction of movement caused by contact of the container with an element moving in a direction opp site to the direction of movement oi! the container is very apt to chip or otherwise mar, or even upset the containers. In iact, in filling machines ofthe type wherein a single dial is relied upon to position and remove containers with respectto the filling table, it is necessary to provide upstanding container engaging elements on the container supports of the filling table to insure that the containers will not be overturned during transfer with respect to the filling table. The

ing machines because the contents oi the containers are very apt to be vagitated, with resultant foaming and loss of a portion 0! the contents of the bottle or other container.

The filling machine or the present invention includes rotary syruping and crowning mechanisms and a rotary dial to remove containers from the syruping mechanism and position them upon the filling table, and a second dial to remove containers from the filling table and position them adjacent the crowning mechanism. By this arrangement, the movement of the containers through the machine is smooth and there are no sharp changes in the direction of movement of the container. In particular, the arrangement of the mechanisms is such that there is no sharp change of direction of the movement of the containers when either moving upon or leaving the filling table.

Another important 'obj ect of the invention is to provide a filling machine wherein the drive for the various mechanisms is centralized, result-'- ing in econo'myof space and agreater smoothness of performance of the machine.

Other objects and advantages of the invention will be apparent ,from the following specification and drawings wherein:

Figure 1 is a plan view of the stationarygwork" table of the machine with the upper portions Figure 41s a vertical sectional view on the line 4-4 of Figure 1;

Figure 5 is a vertical sectional view on the line 5-5 of Figure 1; and

Figure 6 is a vertical sectional view on a line generally corresponding to the line 6-6 of Fig- The numeral l0 designates the stationary work table-of the machine, including a top surface ll over which the bottles or other containers are moved during their passage, to and from the rotary filling table l2. Only a smallpcrtion of the rotary filling table I2 is indicated in the drawings, this table being of the same general construction as that described and claimed in the patent of Huntley and Stewart for rims: machine, No. 2,145,765, issued January :1, 1939, and

being provided with vertically movable bottle supports or platforms l3, each bottle support having a filling head, not shown, vertically aligned therewith.

A rotary syrupin mechanism It is journaled in the stationary table II, the syruping mechanism including a plurality of vertically reciprocable syruping heads I! of the type disclosed in the Huntley and Stewart application. The syruping mechanism also includes a rotary table il fiush with the upper surface II of the work table I II, and -a rotary dial l3 having container pockets therein aligned with the syruping heads II. The syruping mechanism includes a hollow shaft l3 suitably journaled for rotation in the base pertion of the work table l||.- Suitable mechanism such as described in the above mentioned Huntley and Stewart application is provided to enable the syruping heads of the syruping mechanism .to be positioned at various heights with respect to the surface ofthe work table so that bottles of different heights may be handled in the machine.

The crowning mechanism 22 includes a plurality of crowning heads 23. A hollow shaft 24 rotatable in the work table III supports the crowning mechanism and carries.a rotary table fiush with the upper surface ll of the stationary work table and on which the bottles are supported during crowning. A dial 23 is also carried by the hollow shaft 24 above the rotary table 25 to align the bottles with the crowning heads 23. The crowning mechanism 22, like the syrup-' ing mechanism I5, is vertically adjustable to enable it to operate upon bottles of various heights.

As best shown in Figure 1, a straight line conveyor extends across the front portion of the work table "I. In the operation of the machine, bottles to be filled are positioned upon the straight line conveyor and move into the filling machine from the left (Figure l). A rotary infeed dial 3| provided with pockets 32 removes the bottles from the straight line conveyor 30 and conducts them through an arcuate course as indicated by the arrows in Figure 1 to position them upon the rotary table I! of the syruping mechanism H3. The infeed dial 3| preferably includes bottle engaging flanges formed of fibre to prevent any marring of the incoming empty bottles. A suitable gate mechanism 33 of the type described .in the patent of Wiltie I. Gladfelter for Bottle handling machine and control therefor, No. 2,013,144, issued September 3, 1935, is provided adjacent the infeed dial 3| to insure that bottles will be properly delivered to this dial and so that the machine will be automatically stopped in the event that any jamming of the bottles should occur.

The bottles are retained in the pockets 32 of the infeed dial 3| by a guide plate secured tained in the syruping mechanism IS, a guide plate 33 is provided on the upper surface of the work table II, this plate including an arcuate edge 33 conforming to the path of movement of bottles with the syruping mechanism.

A transfer dial 40 including pockets 4!. is positioned between the syruping mechanism "and the rotary filling table l2, this dial, in cooperation with a stationary guide arm 43a secured to the work table ll, serving to remove bottles from the pockets Ila of the syruping mechanism and properly position them upon the bottle supports H of the filling table. As will be observed from the arrows in Figure l, a bottle moving with the transfer dial 40 toward and upon a bottle support I 3 of the filling table will be moving in the same direction as the filling table. There will thus be no sharp change of direction of movement of the bottle at this moment and all possibility of the bottle being overturned will be obviated. In view of this. the bottle supports l3 need include no upstanding shoulder or bottle engaging arms .to prevent upsetting of the bottle, as is necessary in the usual types of filling machines. The bottles are retained in the transfer dial 43 by a guide plate 44 secured to the work table In and including an arcuate portion 45 which surrounds the portion of the path of travel of the dial 40 over which bottles move. Guide plate 44 extends out over the path of movement of the bottle supporting platforms l3 of the rotary filler I! so that the bottles will be properly guided into position on the platforms by the cooperation of the to the upper surface ll of the work table l0,

dial 40 and the guide plate.

The bottle positioned upon a support II of the filling table I! will move about with the filling table to be filled in the manner described in said application of George J. Huntley and Robert J. Stewart, and, when the fillling is completed, will again come adjacent the stationary table Ill and in contact with a right hand arcuate portion 45 of the guide plate 44. A second transfer dial 48 provided with bottle engaging pockets 49 is provided to remove the bottles from the bottle supporting platforms l3, dial 48 cooperating with an arcuate edge 46 of the guide plate 44 to remove the bottles and to transfer them to the rotary table 25 of the crowning mechanisms 22. It will be noted that the bottles are removed from the filling table l2 by a movement which is substantially a continuation of their movement with the filling table. In other words, the direction of movement of the bottles will not be sharply reversed as is the case with types of filling machines now used.

The bottles will be crowned during their movement with the crowning mechanism 22, and will then be removed from the table 25 and dial 25 of the latter mechanism by an outfeed dial 52 provided with pockets 53 and which is substantially surrounded byan arcuate edge 54 of the guide plate 35. By the cooperation of the guide plate 35 and outfeed dial 52, each bottle will be positioned upon the outfeed end of the straight line conveyor 30 to be removed from the machine. A guide element 5| secured to the upper surface ll of the work table I0 extends beneath the crowner dial 26 to guide bottles from that dial to the outfeed dial 52.

The arrangement whereby the above described elements of the present machine are rotated is as follows:

As best shown in Figure 6, a driving motor 50 is mounted in the stationary table Ill, preferably adjacent the front and central portion thereof.

of the frictional change-speed type. and which serves to drive a belt 82 also moving about a pulley "on the shaft 84 of a speed reduction unit 88 mounted in the central and rear portion of the work table base. As shown in Figure 2, the-speed reduction unit 88 has'a vertical drive shaft 88 extending upwardly therefrom and having a drive pinion 81 secured thereto. Pinion, 81 meshes with an idler pinion 88 fixed tova stub shaft 88 suitably iouma'led in the framework of the stationary table l8, and which meshes with pinions .12 and" fixed to the shafts I4 and I5, respectively. Shaft 14 carries the transfer dial 40 and shaft" carries the transfer dial 48, and, as will be observed from Figure 2, the idler gear 68 is between these two shafts. -Shaft 14 carries a pinion 18 adjacent its upper end and which the pathvof movementof a platform l8, a bottle being transferred from the dial 48 will beposimeshes with a large ring gear I8 carried adjacent the edge of the filling table 12.

The hollow shaft i8 '01 the syruping mechanism has a pinion 82 secured adjacent its lower end,

which pinion meshes with the pinion 12 on the dial shaft 14 and pinion 82 also meshes with a pinion 88 on the vertical shaft 84 which carries the infeed dial 8|. The crowning mechanism 22 is driven from the pinion 13 associated with transfer dial 48, a pinion 85 on the hollow shaft 24 of the crowning mechanism meshing with pinion 18. Pinion 85 of the crowning mechanism in turn drives the pinion 88 secured to the shaft 81 which carries the outfeed dial 82.

It will be observed from Figure 2 that the shafts or axes of rotation of the syruping and crowning mechanisms, the two transfer dials and the rotary filler l2 are arranged along a substantially V-shaped figure, with the filling table shaft or axis at the apex of this figure and with the driving gear 81 of the speed reduction unit 65 positioned substantially centrally within the V-shaped figure. It will also be observed that the shafts 84 and 81 of the infeed and outfeed dials 3i and 52, respectively, form a substantially symmetrical polygonal figure, with the drive shaft 86 of the speed reduction unit positioned substantially centrally of this figure.

All of the various dials of the present machine are removable from their shafts so that dials of different diameters and with different size pockets may be substituted therefor to handle containers of various sizes. The dials I8 and 26 of the syruping and crowning mechanisms, respectively, are diametrically split as best shown in Figure 1 in order that they will be removable. The guide plates 38, 44 and 58 are also replaceable by plates adapted to cooperate with dials of different diameters. At B, in Figure 1, there is indicated a bottle of the size intended to be handled by the guide plates and dials illustrated in the assembly of Figure 1. This bottle is represented as moving along an arcuate line L which is equi-distant from the innermost point of the pockets of the dials and the guiding edges of the guide plates. If the dials and guide plates are replaced by other dials and guide plates adapted to handle a large bottle, for example, as represented by the dotted lilies B in Figure 1, it is only necessary that the pockets of the substituted dials and the guiding edges of the substituted guide plates also be equi-distant from the center line L of the path of travel of the bottles.

It will be noted that the relation of the various thereof will. in eifect, intermesh when a bottle isbetween them. The tear or pushing corner 4la ofeach pocket 4| onjthetransfer dial 40 is of such curvature that with the transfer dial 48 and the filling table II rotating at their proper speeds, and with the path of movement of the pushing edge 4la diverging along a line D from tioned ,with its vertical axis substantially in ali ment with the vertical axis of the fillin! nozzle positioned above that bottle supporting platform. Since the dial 48 and the platform will be moving in the same direction at this moment, there will be no possibility of the container being over-turned, and flush top bottle platforms may thus be used in the machine, an arrangement which has been impossible with previous high speed filling machines. The elimination of the guide shoulder ordinarily used on the bottle platforms of course removes another element against which containers have previously had to contact when moving through a filling machine.

The above-mentioned smooth handling of con tainers, coincidental with the provision of paths of proper length about the syruping and crowning bottle handling elements is such that the pockets mechanisms, is brought about by the fact the I axes of the syruping mechanism I5 and the crowning mechanism 22 are on a line whichwould extend parallel to a line tangential to the filling table l2, while the transfer dials 40 and 48, as well as the infeed dial 8| and outfeed dial 52, are arranged in pairs on other lines extending parallel to the above-mentioned lines. It is further contributed to by the fact that all of the dials, including the syruping and crowning mechanism dials or spiders, move the containers through arcuate pathswhi-ch preferably have equal radii. 1

It will be understood that the invention is not limited to the details of construction shown in the drawings, and that the example of the use of the machine which has been given does not include all of the uses of which it is capable; also that the phraseology employed in the specification is for the purpose of description and not of limitation.
