Definitions

  • the invention relates to a filling element according to the preamble of claim 1.
  • the disadvantage here is that a gap remains in the area of the shaft between the filling tube and the housing, which gap lies outside the cleaning channel and in which germs, bacteria, etc. can settle, which are particularly significant when the filling material is particularly critical with regard to sterility and sterility Disadvantages and problems can lead to filling. This applies when filling fruit juices, but especially when filling milk or milk beverages.
  • the object of the invention is to show a filling element which enables the filling of liquid contents into bottles or similar containers which is substantially improved with regard to sterility and sterility.
  • the cleaning channel is formed at least between the two areas, on which the shaft of the tubular or rod-shaped element of the filler element is preferably supported directly on the housing via the seal and at an axial distance from this seal, the system or support for the tubular or rod-shaped element is only occasionally caused by projections or webs or by the contact surfaces formed there, that is, intensive cleaning or flushing is also possible in this area of the mounting or support of the rod-shaped or tubular element in the housing, so that there are practically no spaces or areas, such as slits, etc. that are not or only barely covered during cleaning, and on which germs or bacteria could settle.
  • a centering ring is used for centering the container, which is located on its radially outer, i.e. side facing away from this machine axis is open.
  • This makes it possible to feed or discharge the containers to be filled or the filled containers radially to the machine axis, specifically when the centering ring is positioned at a level which is below the mouth of the containers. This effectively prevents containers from coming into contact with their mouth against the centering ring and thus becoming contaminated in the area of the particularly critical mouth or contaminated with germs or bacteria.
  • 1 is the filling element of a rotating type of filling machine.
  • the filling element 1 is provided with a plurality of similar filling elements 1 on the circumference of a machine part rotating around a vertical machine axis.
  • a bottle plate 2 which can be moved up and down by a lifting device, not shown, is provided as a container carrier, on which the respective bottle 3 stands with its bottom for filling with a liquid filling material.
  • Each filling element 1 has a filling tube 4, which is arranged with its axis in a vertical filling element axis VA, which is also the vertical axis of the bottle 3 to be filled.
  • the filling tube 4 projects with a partial length 4 ', which includes the lower end of the filling tube, over the underside 5 of a housing 6 and is at a partial length 4''(shaft) enclosing the upper end of the filling tube 4 inside the housing 6 or held in an essentially cylindrical section 7 'of a bore 7 of a housing part 6', to the lower end face 5 'of which a housing part 6''connects in a sealed manner and which covers the underside 5 of the Housing forms.
  • the housing part 6 ′′ has an opening or bore 8 through which the filling tube 4 extends with a part length 4 ′′ ′′ lying between the part lengths 4 ′ and 4 ′′.
  • the filling tube 4 has a collar 9 which projects radially beyond the outer surface and on which the filling tube 4 has an enlarged outer diameter.
  • this collar 9 is arranged in a section 7 ′′ of the bore 7 and with a larger, lower axial partial length, the collar 9 is located in the bore 8.
  • the collar 9 is on a lower, conical end face to hold the filler tube 4 in the housing 6 by a spring-loaded clamping bolt 10 of a locking element 11 provided on the housing part 6 ′′.
  • the housing part 6 ′′ consists of an electrically insulating material.
  • the locking element 11 or its clamping bolt 10 which is directed radially to the filling tube 4 and abuts the filling tube 4 with its end face, is also used at the same time for establishing an electrical connection to a probe or electrode covering formed on the outer surface of the filling tube 4 below the collar 9 12.
  • the filling tube 4 is provided on its outer surface with a seal 13 concentrically enclosing the axis VA, which is partially from a seal there Annular groove of the filler tube 4 is received and the filler tube 4 at the upper end of the filler tube 4 is seated tightly in the bore 7 or in the section 7 'and thus an outwardly tight transition between the liquid channel 14 formed in the housing 6 and the channel 15 the filling tube 4 is effected.
  • the liquid channel 14 at the transition to the filling pipe 4 or to the bore 7 has a diameter which is slightly smaller than the diameter of the bore 7, so that within the housing part 6 'at the transition between the Liquid channel 14 and the bore 7 an annular shoulder 16 is formed.
  • the upper end of the filling tube 4 is at a distance from this shoulder 16, as a result of which spaces which are difficult to access when cleaning are avoided in the liquid path for the filling material, especially at the transition from the liquid channel 14 to the channel 15.
  • the bore 7 is designed in section 7 ′′ so that it has a plurality of projections or webs 17, which are distributed at equal intervals around the axis VA and are each provided at their radially inner end with an arc-shaped curved contact surface 18, and in such a way that the contact surfaces 18 of all the webs 17 lie on an annular surface concentrically surrounding the axis VA, the radius of which is approximately the same or slightly larger than half the outer diameter which the filling tube 4 has in the region of the collar 9.
  • the filling tube 4 with the collar 9 is thus supported radially on the housing part 6 ′ on each web 17 or on the contact surface 18 there.
  • each web 17 has an area above the contact surface 18, on which the radially inner one Surface of the web 17 has a distance from the axis VA corresponding to half the smaller diameter of the section 7 '.
  • a step or a further contact surface 19 is thus formed on the contact surface 18 in the axial direction upwards, on which the filling tube 4 with the upper end face of the collar 9 is supported axially on the housing part 6.
  • the contact surface 19 is slightly beveled, ie all contact surfaces 19 each formed in the area of a web 17 lie on an imaginary conical ring surface which also concentrically surrounds the axis VA.
  • section 7 ′′ each has a groove-like area 20 with a substantially larger radius or cross section. These groove-like regions 20 extend axially beyond the contact surfaces 19 from the transition region of the two housing parts 6 ′ and 6 ′′ in the housing part 6 ′.
  • the bore 7 with the cylindrical region 7 'and with the region 7''with the above-described design is made in such a way that first a number of individual bores on an imaginary circular line enclosing the axis VA from the lower end face 5' of the housing part 6 ' with a depth corresponding to the axial length of section 7 'in such a way that between these individual bores which form the later regions 20, the material which later forms the webs 17 remains. Subsequently, a central bore is made in the same axis as the axis VA, the diameter of which corresponds to section 7 '. This central bore, which intersects the individual bores, then creates the regions 20, which are approximately semicircular in section in FIG. 2, with the webs 17 lying between them. To produce the contact surfaces 18, this central bore is then produced from the front side 5 'of the housing part 6 with a slightly larger diameter drilled again.
  • the work described above is carried out on a suitable machine, for example on a boring machine or another suitable machine tool.
  • the described design ensures that the filler tube 4 is supported radially and axially in the region of the collar 9 only at certain points in the housing part 6 ', that is to say the ring channels formed in the region of the section 7' or the bore 8 not only in the region of the section 7 '' are connected to one another, but also in section 7 '' a channel is formed which surrounds the filling pipe 4 or the collar 9 there, in which the outer surface of the filling pipe 4 is accessible except for a negligible small part.
  • the design described and in particular the described mounting of the filling tube 4 or the partial length 4 ′′ in the housing part 6 ′ thus permits optimal cleaning and sterilization of the filling tube 4 and all critical areas, in particular also the area of fastening this filling tube 4 in the housing 6 , which significantly improves sterility and sterility when filling, especially with such filling material (eg fruit juices or Milk), which requires special sterility and sterility.
  • filling material eg fruit juices or Milk
  • the filling tube 4 is a short filling tube in the embodiment shown and, when filling a bottle 3, extends only through the opening at the mouth 3 'of this bottle with part of the partial length 4' into the interior of the bottle 3, which when filling with the liquid Filling material is arranged with its mouth at a distance below the underside 5 and is open to the environment in the area of this mouth 3 '.
  • the filling pipe 4 has at its lower end a distributor head 23 with a plurality of openings 24, through which the liquid filling material flows to the interior of the bottle 3 to be filled when the liquid valve 21 is open.
  • the openings 24 are each distributed at uniform intervals around the axis VA, and in each case at a radial distance from this axis.
  • the openings 24 are designed such that, when the liquid valve 21 is open, each opening 24 generates a jet of the filling material which is directed radially outward with respect to the axis VA and which strikes the inner surface of the wall of the bottle 3 surrounding the filling tube, ie in the embodiment shown the inner surface of the fuselage area 3 ''''.
  • the axes of the openings 24 are provided running radially or approximately radially to the axis VA and, in the embodiment shown, each form an angle with the axis VA of less than 90 ° , which opens downwards, ie towards the bottle plate 2.
  • the distribution or the distance between the openings 24 are chosen so that between the Jets of two adjacent openings 24 each leave an intermediate space through which the air displaced by the liquid filling material (return air) can flow off.
  • the associated bottle plate 2 is lowered in the usual way so that the distributor head 23 is located above the mouth 3 'of this bottle.
  • the bottle plate 2 with the bottle 3 is then raised so far that the filling tube 4 extends through the mouth 3 'of the bottle 3 and the distributor head 23 is located inside the bottle 3.
  • the bottle plate 2 is lowered again to pull off the filled bottle 3.
  • each filling element 1 In order to center a bottle 3 to be filled on the respective filling element 1 with respect to the axis VA when the bottle plate 2 is lifted before the filling phase is initiated, each filling element 1 has a centering ring 25 which, by means of two guide rods 26, runs parallel to the axis VA on one lower position is held displaceable.
  • the centering ring 25 is an open ring which has an inner, annular, centering surface 27 which is concentric to the axis VA and which is interrupted at an opening 28 of the centering ring 25.
  • the width of the opening 28 is somewhat larger than the outside diameter that the bottles 3 do not have in an area, for example in the area 3 ′′ below the mouth 3 ′ or below beads 3 ′′ ′′ provided in the area of this mouth, for the purpose of fixing one bottle cap shown.
  • the opening 28 points radially outwards.
  • the lowest position of the centering ring 25 is set taking into account the lower stroke position of the bottle plate 2 when feeding and taking away the bottles 3 and taking into account the size or height of the bottles 3 so that the lowest position of the centering ring 25 corresponds to a level at which the area 3 '''of a bottle 3 placed on the lowered bottle plate 2 is located.
  • the centering with the interrupted centering ring 25 takes place each time this ring comes to bear against the widening trunk area of the bottle 3.
  • the invention has been described above using an exemplary embodiment. It goes without saying that numerous changes or modifications are possible without departing from the inventive idea on which the invention is based. For example, it is possible to use an even shorter or a longer filling tube instead of the filling tube 4.
  • the type of mounting in the housing 6 of the filling element 1 described above for the filling tube 4 can also be used for other tubular, rod-like or probe-like elements of a filling element, in particular also for those filling elements in which the bottle 3 is filled is arranged with its mouth 3 'in the sealing position with a seal of the filling element.
  • the cleaning and rinsing channel formed by the bores 7 and 8 and the channel 22 can also be used to discharge the return gas during filling, ie as a return gas path serve.
