Definitions

  • the invention relates to a device of the type mentioned in the preamble of claim 1.
  • beverage filling devices usually have a larger number of circumferentially arranged filling elements. These have an edge seal at the beverage outlet, which comes into sealing engagement with the container edge in order to avoid the lateral leakage of liquid during filling and to prevent pressure losses at this point in the case of vacuum filling or counter-pressure filling.
  • edge seal at the beverage outlet, which comes into sealing engagement with the container edge in order to avoid the lateral leakage of liquid during filling and to prevent pressure losses at this point in the case of vacuum filling or counter-pressure filling.
  • the edge of the container must be pressed against the container edge seal. The force required depends on the container pressure and also the weight of the filled container.
  • a lifting device usually with a hydraulically or mostly pneumatically actuated lifting cylinder, which lifts the container and presses it against the container edge seal of the filling element with the required contact pressure during the filling process.
  • the first-mentioned, not generic known construction is characterized by a mechanically very complicated structure, in particular of the control mechanisms.
  • the last-mentioned known design of the generic type requires an expensive cylinder, which must either be depressurized after lowering the filling, with expensive pressure medium being lost or having to be pressed down against the pressure of the pressure medium, which in turn requires considerable mechanical effort.
  • the object of the present invention is therefore to provide a device of the type mentioned at the outset, which is structurally simple and works without major pressure medium losses.
  • the container is held in the pressure position by applying vacuum to the intermediate space between two opposing surfaces. These only come into non-positive vacuum engagement at the height of the pressure position, that is to say when the container engages with the container edge seal of the filling element, and holds the container in sealing engagement.
  • the lifting movement for lifting the container into the sealing position and for the subsequent lowering can take place with a separate, very easily constructed device, for example via a lifting curve or the like.
  • This completely new construction is structurally simpler to design than the known constructions, in particular by eliminating the long cylinder.
  • the features of claim 7 are also advantageously provided.
  • the surfaces to be brought into vacuum engagement can be provided on one side outside the container.
  • the surfaces are ring-shaped around the filling element, for example in the form of an annular piston or the like, the advantage results symmetrical application of force without risk of canting.
  • the construction can also be made more compact.
  • FIG. 1 shows schematically a filling element 1, on the bottom of which a container edge seal 2 is indicated schematically in the form of a rubber ring, against which the edge 3 of a container 4, in the case shown a bottle, is to be pressed in sealing engagement for filling.
  • a container edge seal 2 is indicated schematically in the form of a rubber ring, against which the edge 3 of a container 4, in the case shown a bottle, is to be pressed in sealing engagement for filling.
  • the container shown stands on a lifting plate 5, which runs over a rod 6 and an axis 7 with a roller 8 on a lifting curve 9, which is supported at 10 in a stationary manner.
  • a lifting plate 5 which runs over a rod 6 and an axis 7 with a roller 8 on a lifting curve 9, which is supported at 10 in a stationary manner.
  • a rod 11, 12 engages the rod 6, the vertical rod 12 being displaceably displaceable in the rod direction in a fixed guide 13 and being secured against rotation of the rod.
  • a plate-shaped surface 14 is fastened horizontally in the exemplary embodiment.
  • a counter surface 15 is fixedly attached to the filling element 1 via a linkage 16, 17.
  • the counter surface 15 has a horizontal flat edge region 18, is bulged somewhat in the middle, as shown, and has a vacuum connection 19 there.
  • the heights of the surface 14 and the counter surface 15 are selected such that the edge 18 of the counter surface 15 comes into sealing gap engagement with the surface 14 when the edge 3 of the container 4 sealingly engages against the container edge seal 2. Once this height position has been reached, the area between surface 14 and counter surface 15 is evacuated via vacuum connection 19. The lifting plate 5 is now held up due to the vacuum force between surface 14 and 15 and presses the container with the required sealing force against the filling element. The sealing force results from the vacuum pressure multiplied by the vacuum-applied surface between the surface 14 and the counter surface 15, here essentially within the marginal gap 18.
  • the vacuum can also be supplied to the lower surface 14 instead of to the upper counter surface 15, for example via a flexible vacuum line 19.
  • the vacuum at the vacuum connection 19 is switched off by suitable control devices and the area between the surface 14 and the counter surface 15 is ventilated.
  • the lifting plate 5 with the container 4 can be lowered again on the lifting curve 9 raised in this circulation region of the filling device.
  • the lifting and pressing attack on the container 4 does not take place from below by means of a lifting plate 5, but, as shown in dashed lines in FIG. 1, in the neck area with a pair of pliers 20 which are connected by a rod 21 is attached to the rod 11.
  • the lifting plate 5 is omitted in this case.
  • FIGS. 2 to 5 show variants of the vacuum pressing device 14, 15 according to FIG. 1, the other construction details of the device shown in FIG. 1 being able to remain unchanged.
  • both surface 24 and counter surface 25 are designed as flat, preferably round plates, with a circumferential edge on surface 24 Rubber ring 26 is arranged as a seal. This replaces the gap seal 18 of the embodiment in FIG. 1 and, because of its elasticity, ensures a good and slightly height-tolerant vacuum seal
  • the counter surface 35 is designed in accordance with that of the embodiment of Figure 2 as well as the surface 34, but on which instead of the rubber ring 26 a bellows 36 is arranged, which carries at its upper end a sealing ring 37, which is used for sealing engagement with the counter surface 35 is provided.
  • the bellows 36 is held in diameter stable against the acting vacuum force by inserted rings or the like. After sealing engagement and vacuum application, this construction results in a frictional engagement over a considerable height range of several centimeters. With this construction, containers 4 of different heights can thus be processed without structural changes to the system.
  • the counter surface 45 is designed as the lower end surface of a piston 47, while the surface 44 is designed as the bottom surface of a cylinder 46.
  • the vacuum seal is provided by the mating cylinder surfaces of the piston 47 and the cylinder 46.
  • FIG. 5 shows a construction which largely corresponds to that of FIG. 4, in which only the arrangement of piston 57 and cylinder 56 is interchanged.
  • the vacuum connection 19 can take place on the upper fixed part, that is to say the counter surface 15, 25, 35, 45, 55 or on the lower part, that is to say the surface 14, 24, 34, 44, 54.
  • FIG. 6 shows a construction which differs fundamentally from the previously illustrated embodiments in that the vacuum engagement device is designed concentrically to the container 4.
  • the lifting device for the container 4 with its edge 3 to be sealed is designed accordingly as in FIG. 1.
  • the rod 12 guided perpendicularly at 13 is provided, which is guided over a roller 8 on the lifting curve 9 and alternatively moves the container 4 in height via the pliers 20 or the plate 5 (shown in dashed lines).
  • annular piston 63 is provided at the upper end of the rod 12, and the surface 64 is formed in an annular manner at the upper end thereof.
  • the annular piston 63 fits into an annular cylinder 66 of the filling element 61, the upper annular surface of which forms the counter surface 65, in which the vacuum connection 19 opens.
  • the ring piston 63 simultaneously plunges into the ring cylinder 66 so that surface 64 and counter surface 65 (both formed as ring surfaces) are then applied by vacuum ) apply the necessary contact pressure against each other.
  • the construction can also be designed in the case of FIG upper end of the rod 12, a cylinder is seated, which comes into engagement with a piston formed on the filling member 61.
  • FIGS. 7 to 10 show embodiment variants of a fundamentally different type of training, in which the contact pressure is exerted directly on a bottle by a vacuum attack.
  • FIG 7 shows again the filling element 1 with the container edge seal 2, essentially in accordance with the construction of the embodiment of Figure 1.
  • two concentric rigid walls 71 and 72 are provided on the lower surface of the filling element 1, each of which carries a sealing ring on its lower edge .
  • the shape of the concentric walls 71 and 72 with their lower ring seals sealingly engage the widening shoulder area of the bottle 4 in order to seal a surface area 74 of the bottle between them .
  • the vacuum generated by the vacuum connection 19 between the walls 71 and 72 acts on this surface area 74 in the direction against the ring-shaped counter surface area 75 on the underside of the filling element 1.
  • This construction therefore does not use one as the surface acted upon by the vacuum, as in the embodiment in FIG separately provided surface 14, but an annular surface area 74 on the bottle itself. This results in an extremely space-saving construction, which, as additional components compared to existing known constructions, only that two concentric ring walls 71 and 72 and a corresponding vacuum connection required.
  • Figure 8 shows a variant of Figure 7, which works essentially the same way. Instead of two concentric walls 71 and 72, however, only one outer wall 82 is provided. In this construction, the mating surface area 85 extends between the ring wall 82 and the container edge seal 2, as does the surface area 84 on the shoulder area of the bottle 4, which extends between the lower edge seal on the ring wall 82 and the container edge seal 2. In this embodiment, the container edge seal 2 must directly seal the vacuum applied for suction against the overpressure that may be present in the container, which is not the case in the embodiment in FIG.
  • Figure 9 shows a variant which largely corresponds to the construction of Figure 8.
  • a bellows 92 which is flexible in the longitudinal direction is provided, the diameter of which is advantageously stiffened against the acting vacuum force.
  • the advantage of the bellows in this construction is that the ring seal 93 provided on the lower edge of the bellows can better fit on the bottle 4 if, for example, it is asymmetrically skewed due to shape inaccuracies.
  • FIG. 10 finally shows an embodiment variant, which in turn largely corresponds to the embodiment of FIG. 8.
  • the ring wall 102 attached to the underside of the filling element 1, which largely corresponds to the wall 82 according to FIG. 8, is selected here in diameter so that it does not grip the shoulder area of the bottle from above, but rather the bottle in comprises its largest diameter and seals there radially against the circumference of the bottle with an annular seal 103.
  • Such a construction is advantageous under the embodiment of FIG. 8 if the bottle is more precisely worked on its outer circumference than in the shoulder area and is also characterized by a height tolerance.
