Definitions

  • the invention relates to a filling element according to the preamble of claim 1.
  • Filling elements are known in a wide variety of designs, in particular also in a design according to the preamble of claim 1 (DE-OS 38 09 852), which can be used, inter alia, in a method or in a filling machine for aseptic or sterile filling of a liquid filling material Containers, especially in bottles.
  • the known filling element is designed as such with a filling tube which protrudes over the underside of the filling element.
  • the actual filling phase which is initiated when the liquid valve is opened, is preceded, inter alia, by the treatment or sterilization of the respective container with a hot sterilization medium, preferably with steam.
  • the filling tube is connected via a controllable sterilization medium connection formed in the filling element to a source for the hot sterilization medium, so that this emerges at the lower end of the filling tube protruding into the container.
  • the end of the filling tube ie the exit point for the sterilization medium determined by this end during the sterilization, is arranged so deep in the container with a small distance from the container base that the container base is adequately loaded with the sterilization medium and For example, along the bottom of the container radially to the axis of the container or to the axis of the filling element or the filling tube to the outside and then from the bottom of the container, in particular along the inner surface of the circumference of the container, there is an intensive flow of the sterilization medium and thus an optimal sterilization of the interior of the container also in the lower area , ie in particular on the inner surface of the bottom, the container circumference and at the angle formed between them.
  • a disadvantage of this known filling element is, among other things, that a relatively large stroke for the container arranged on a container carrier is required for the insertion of the filling tube, which is longest for optimal sterilization, into the container - until the container lies tight against the filling element (sealing position) is. A relatively long cycle time is thus also required until the container has reached the sealing position and the pressure of the hot sterilization medium can be applied to the interior of the container, as is necessary in many cases in order to achieve an optimal result for the sterilization.
  • the object of the invention is to show a filling element with which optimal sterilization can be achieved despite shortened strokes and despite the possibility of shortening the cycle times.
  • the filler element according to the invention is one without a filler tube or one with a short filler tube, so that a short stroke and thus a short cycle time are sufficient for attaching and removing the respective container to or from the filler element.
  • the tube designed as a sterilization tube is moved from its upper stroke position into its lower stroke position, in which the lower end of this tube provided with at least one outlet opening is deep in protrudes into the container, with the smallest possible distance from the bottom of the container, so that an optimal sterilization of the entire container interior is possible with a small amount of sterilization medium and in a short treatment time.
  • the sterilization tube and the parts connected to it in particular also for the movement of the Tube provided actuator can be formed with low mass. There is therefore no need for large mass accelerations, which is particularly important in the case of a filling machine running at high power.
  • the control elements controlling the respective filling element also control the sterilization tube and the associated actuating device in such a way that at least during the filling phase, but preferably also during a pre-stressing phase possibly preceding this filling phase, in which the interior of the container in the sealing position with the filling element is pretensioned to a predetermined pressure, the sterilization tube is in the upper stroke position in such a way that this tube is not damaged in the event of a burst or breakage, possibly defective containers, and above all is protected so that liquid contents cannot accumulate on the tube , which also contributes to increasing the quality of the sterilization.
  • the actuating device is designed such that the sterilization tube is moved into the lower stroke position by the pressure of the sterilization medium and is held there. This not only simplifies the actuating device and the associated control, but also ensures that the sterilization tube is in the lower stroke position when hot sterilization medium emerges from this tube.
  • the sterilization medium emerges at the lower end of the sterilization tube.
  • the sterilization medium supplied into the container for example via a gas channel
  • the sterilization medium discharged from the container via the lower end of the sterilization tube it also being possible here, for example, for any condensate or condensate residues to be contained in the sterilization medium drain the sterilization tube.
  • the sterilization tube it is also possible to connect the sterilization tube to a source for a vacuum in order to evacuate the container via the sterilization tube, preferably also to remove liquid or condensate.
  • control is also possible in such a way that hot sterilization medium emerges from the sterilization tube already in the upper stroke position, which makes it possible to treat those parts with the sterilization medium that are in the area with the container even before a container is attached come into contact with the container mouth.
  • the sterilization tube is inserted into the respective container to such an extent that the sterilization medium is sufficiently applied to the container base.
  • 1 is a ring bowl which is provided on an otherwise not shown rotor of the filling machine which rotates around a vertical machine axis and which serves to fill the bottles 2 with a carbonated beverage, for example beer, under counterpressure.
  • a carbonated beverage for example beer
  • a multiplicity of filling points are formed on the circumference of the rotor or ring bowl 1, each of which has a filling element 3 and beneath it a bottle holder which can be moved up and down in the vertical direction.
  • the filling elements 3 are attached to the circumference of the ring bowl 1.
  • This forms an inner space 4 which surrounds the vertical machine axis and which is filled up to a predetermined level N with the beverage or with the liquid filling material, so that below the level N a liquid space 4 'occupied by the liquid filling material and above the level Gas space 4 '' is formed for a gas under pressure, for example inert gas (for example CO2 gas).
  • inert gas for example CO2 gas
  • Each filling element has a housing 5, in the lower part of which a liquid channel 6 is formed, which is connected at one end to the filling space 4 'and on the underside of the filling element 3 or the housing 5 a ring-shaped ring concentrically enclosing the vertical filling element axis FA Dispensing opening 7 forms.
  • the liquid valve 8 is provided, which is shown in its open position in FIG. 1.
  • This liquid valve consists of a valve body 9, which can be moved by a predetermined movement stroke in the direction of the axis FA by actuating means (not shown in more detail) and, in the closed state of the liquid valve 8, rests with a valve body surface against a valve seat formed in the liquid channel 6.
  • 10 denotes a centering bell and 11 denotes an annular seal enclosing the discharge opening 7, against which the bottle 2 located in the sealing position with the filling element 3 bears with its mouth 2 '.
  • annular residual gas channel 12 which is common to all filling elements 3, is provided in the ring bowl 1. Furthermore, a supply channel 13 for the sterilization medium, namely for water vapor, which is also common to all filling elements 3, is provided on the ring bowl 1 or on the rotor having this ring bowl.
  • Each filling element 3 has a sterilization tube 14 which is arranged coaxially with the axis FA, which is open at its lower tube end 14 'and is guided through the valve body 9 through a bore of the valve body 9 which is coaxially with the axis FA.
  • the outer diameter of the sterilization tube 14 and the inner diameter of the bore mentioned are adjusted to one another in such a way that a gas or annular channel 15 results within the valve body 9 or within a plunger-like extension 9 'which is produced in one piece with this valve body and extends upwards the underside of the filling element 3 is open and is surrounded concentrically by the annular discharge channel 7.
  • the sterilization tube 14 can be displaced in the axis FA by a predetermined stroke such that the tube end 14 'in the upper stroke position is at the same level or approximately as the same level with the lower end of the valve body 9, that is is inserted into the filling element 3 or into the valve body 9 and in the lower stroke position shown in FIG. 1 is inserted so far into the bottle 2 lying in the filling element 3 that the pipe end 14 'is in the immediate vicinity of the inner surface of the bottom 2 '' of the bottle 2 is located, or at least only so far from the floor that the floor is also sufficiently exposed to the water vapor.
  • the actuating device 16 is formed by a cylinder 17, in which a piston 18 is provided so as to be displaceable in the axis FA.
  • the upper, open end of the sterilization tube 14 is attached to the piston 18.
  • a channel 19 which is coaxial with the axis FA and via which the upper, open end of the sterilization tube 14 is connected to the side of the piston 18 facing away from this tube.
  • the space of the cylinder 17 facing away from the sterilization tube 14 above the piston 18 opens into a channel 21 which is connected to the supply channel 13 via an individually controllable and individually controllable electrical control valve 22 for each filling element 3.
  • the part or space of the cylinder 17 provided below the piston 18 can be acted upon by a pneumatic pressure of a control pressure line 45 or vented to the atmosphere via an electrically actuated control valve 23, which is again provided separately for each filling element 3.
  • each filling element 3 has three individually controllable control valves 24-26, which form a control block and control various channels, some of which are formed in the housing 5 of the filling element and some of which are in the ring bowl 1.
  • the control valves 24 - 26 are connected to the following channels:
  • a connecting channel 27 which opens into a channel 28 leading to the residual gas channel 12, and on the output side to a channel 29 which opens onto the inner surface of the cylinder 17 and which is connected to the channel 19 when the piston 18 is in the lower stroke position or when the sterilization tube 14 is in the lower stroke position.
  • the peculiarity of the filling element 3 is that when the sterilization tube 14 is in the upper stroke position, in which the control pressure is applied to the piston 18 on its underside with the control pressure, by opening the control valve 22 a steam outlet at the tube end 14 'and thus on the underside of the filling element 3 is possible in order to sterilize the parts or surfaces there and also the bottle 2 when it is placed in the region of its mouth 2 '.
  • the sterilization tube 14 is completely inserted into the bottle 2, so that the tube end 14 'is arranged in the immediate vicinity of the inner surface of the base 2' '.
  • the pressure of the sterilization medium or steam acting on the upper surface of the piston 18 when the control valve 22 is open is used, with the control valve 23 providing targeted or controlled relief of the space formed below the piston 18 of the cylinder 17 takes place.
  • the cross section of the piston 18 in comparison to the cross section of the sterilization tube 14 ensures that the sterilization medium exerts a sufficiently large pressure on the top of the piston 18, although this sterilization medium constantly emerges at the lower tube end 14 '.
  • a basic advantage is also that the retractable sterilization tube 14 only requires a small stroke despite the optimal sterilization for the bottle carrier 20, and that the retracted sterilization tube 14 is particularly useful when the bottle is in and out, but also in critical phases of the filling process , for example during the preloading of the bottle 2 to the filling pressure, in the retracted state.
  • the filling element 3 enables the following mode of operation:
  • control valve 26 is closed, so that steam is introduced into the bottle 2 via the still open control valve 22 and the sterilization tube 14 until pressure equalization with the pressure in the supply channel 13 is reached.
  • the control valve 22 is closed.
  • the vapor overpressure is discharged into the residual gas channel 12 via the control valve 26 which is opened again.
  • the control valves 24 and 25 are opened, so that inert gas passes from the gas space 4 '' into the bottle 2 via the channels 30 and 31 as well as via the ring channel 15, and in this case the residual steam via the sterilization tube 14, the channel 29, the connecting channel 27 and the channel 28 to the residual gas channel 12 is displaced.

  • the sterilization tube 14 is moved into its upper stroke position by corresponding actuation of the control valve 23, so that this tube is completely retracted into the filling element 3 and is therefore also protected against broken glass bottles.

If the sterilization tube 14 stands with the tube end 14 'in the lower stroke position on the bottom 2''of the bottle 2, then essentially the same conditions can be achieved in the treatment of these bottles regardless of the tolerances of the bottles 2.
