APPARATUS FOR VACUUM FILLING OF CONTAINERS Stanley John Busby, London, England 7 Application July 7, 1949, Serial No. 103,394 In Great Britain July 9, 1948 This invention relates to vacuum bottle or like receptacle filling machines and has for its object to provide an improved vacuum filling head arrangement for such machines.
In. machines of this type in the operation of filling a receptacle, such as, for example, a bottle, the bottle is placed or supported on a platform and its mouth is applied to a filling head against which it is sealed by a resilient washer. A vacuum pipe and a liquid feed pipe project downwardly from the filling head into the bottle. In order to facilitate attachment or removal of a bottle on the filling head and to allow for the flexing of vacuum and liquid supply tubes above the filling head it is necessary to mount the filling head so as to be movable relative to the bracket on which it is supported.
According to one feature of the present invention a vacuum filling machine of the type described comprises at least one filling head pivotally supported about a transverse axis in such manner that it can rotate freely without restraint when engaged by the mouth of a bottle or other receptacle to be filled. The invention also comprises an improved form of the filling head itself which comprises a casing, a spigot member, an outer tube secured at its upper end in the spigot member, and an inner tube disposed concentrically within the outer tube and having at its upper end an outwardly projecting flange received between the casing and the spigot memher, and means for drawing together the casing and spigot member to clamp between them the flange of the inner tube, the co-operating surfaces of the spigot and flange being flat and perpendicular to the axis of the tubes.
The accompanying drawings illustrate an improved vacuum filling machine embodying the features of the present invention.
In the drawings:
Figure 1 is a general side elevation of a doubleheaded vacuum filling machine,
Figure 2 is a plan view of the machine shown in Figure 1,
Figure 3 is a front part section of the filling head mounting arrangement on the line A-A of Figure 2, I
Figure 4 is a section through a filling head on the line B-B of Figure 2.
Referring firstly to Figures 1 and 2 of the drawings there is shown a vacuum bottle filling machine comprising a pair of filling heads connected to a common liquid supply tube 2v by a flexible pipe 2a and a pair of overflow chambers 3, which in turn communicate with a reserve overflow chamber 4 connected to an evaporating 4 Claims. (01. 226-116) pump by a pipe I 6. Figure 1 shows a bottle 5 supported beneath one of the filling heads on a bracket I4 so that its neck encloses an inner liquid feed pipe 8 and an outer concentric vacuum pipe 7. Sealing contact is maintained by the lowermost of a stack of rubber washers 8. The filling heads are supported in a bracket 9 in a manner which will be later described.
In the operation of filling a bottle a partial vacuum is applied through the pipe it to the reserve overflow chamber 4, as by means of an electrically driven pump. This partial vacuum is transferred first to the overflow chambers 3 and then to the vacuum pipe 7 in the filler head through tubes It and i2 and a flexible coupling 12a. The reduced pressure thus created in the bottle 5 causes liquid to enter it by way of the supply pipe 201. and the feed pipe 5. Filling of the bottle continues until the liquid level reaches that of the end of vacuum pipe '5 whereupon excess liquid enters the first overflow chamber 3 through tube l2 and, subsequently, should the bottle not be removed, will fill this chamber and overflow in turn into the reserve overflow chamher 4 by way of tube I l This arrangement efiectively prevents entry or splashing of liquid into the main vacuum supply pipe I ii. All three overflow chambers are provided with liquid return tubes l3 leading to the bulk liquid container (not shown). These tubes are arranged so that as soon as a bottle is removed from the filling head the consequent loss of vacuum in the overflow chamber permits any liquid which may have accumulated therein to flow back by gravity to the bulk container through automatic relief valves 24 and 25. A valve 28 is fitted on the liquid supply tube 2 to prevent re-entry of liquid to the bulk container after filling of a bottle has been effected. A pipe 35 extending from the top of the reserve overflow chamber :3 is connected to a vacuum pressure gauge 29. The level to which a particular bottle is filled is adjusted by varying the number of spacing washers i3 surrounding the pipe i. Bottles of different sizes may be accommodated on the filling "heads by adjusting the position of base supporting brackets i i.
Referring now also to Figure 3, each end of the bracket 9 upon which the two filling heads are supported is provided with a pair of downwardly extending supports !5, each having a vertical guide slot I6. These slots accommodate the shanks of trunnions I! which are screwed inwardly into the casing it of each filling head. The filling heads are thereby permitted to rock freely about their pivotal axes and to be vertically movable to an extent determined by the depth of the guide slots [6. As here shown the top of each support I is bored to receive a coil spring 19 for biasing the filler head downwardly. The lower end of the spring engages over a bearing block 20 shaped to the surface of the associated trunnion l! the upper end of the spring being retained bya shouldered screw 2! recessed into the upper face of the bracket 9. The heads of the trunnions I? are knurled to facilitate removal and assembly. It will be observed that the springs I9 do not oppose rotation-of the filling head, but are for the purpose'of allowing the filling head to yield resiliently in a vertical direction, so that it can accommodate itself .to the mouths of bottles of slightly different heights.
The construction of an individual fillinghead is shown in Figures 3 and 4, and comprises a hollow casing l8 bored with a liquid feed passage 22 leading to its centre anda vacuum feed passage 23, disposed at an angle thereto.
The lower part of the casing l8 receives a spigot member 26 having a central bore 26a and an oblique bore 26b, the casing and the, spigot mem her being held together by a cap 21 adapted to be screwed onto the casing l8 and having an annular flange 21a. engaging an annular recess in the lower face of the spigot member, thereby drawing it towards the casing IS.
The upper surface of the spigot member registers with the casing I8 so that the central bore 26a is in alignment with the inner end of the feed passage 22 and the oblique bore 26b is similarly in alignment with the inner end of the vacuum passage 23. feed and vacuum passages 22 and 23 are con-. nected respectively with the pair of concentric pipes 6 and l supportedby the spigot member 26. The smaller diameter orfeed pipe 6 is inserted in the large diameter or vacuum pipe within which it is supported by an upper flange 6a. The vacuum pipe '5 is sweated, or otherwise attached at its upper end to the spigot member 26. The wall of the vacuum pipe is drilled opposite the adjacent end of the oblique bore 26b. The-arrows in Figure 4 indicate the paths by which liquid enters a container being filled and by which air is extracted to cause such entry to take place.
When the casing l8 and the spigotmember 25 are drawn together on rotation of the cap 21, their flat opposed surfaces abut the upper and lower surfaces respectively of the flange 6a on the inner or feed pipe 6 which is thereby tightly clamped between these parts so as to provide a precision leak proof coupling between the casing l8 and the spigot member 26. 7
It is important that the casing 18 and the spigot member 28 are correctly aligned so as to ensure that the passages in the casing register with the bores in the spigot member. For this purpose a dowel may be formed on the upper surface of the spigot member 26- so as to register in a correspondin recess in the casing i8. Alternatively registration may be effected by means of a rib or key cut in one of the opposed faces adapted to engage a groove or keyway cut in the other opposed face.
The fact that all the abutting surfaces are flat has the advantage that these can be easily and accurately machined to the precision limits required and also offer greater resistance to wear, disfigurement or breakage through casual handling.
It will be understood that this invention is not limited to the partiular machine described and By this arrangement the illustrated, many modifications being possible. For example, the connections of the two concentric tubes in the filling head may be reversed, liquid being supplied through the outer tube and the partial vacuum being applied to the inner tube.
