Definitions

  • the invention relates to a method for filling a vessel with a liquid, in which the vessel is placed on a lifting plate and is brought up to a filler neck up to a predetermined distance measured from its base, the mouth of the vessel being raised into a sealed fill position below the filler neck the vessel is filled up to a predetermined filling level by opening a valve assigned to the filler neck, whereupon the liquid supply is stopped and a volume of liquid present between the valve and the filling level runs into the vessel.
  • bottles are to be filled with a certain amount of liquid. Deviations from these target values specified on the bottles are permitted within the legally prescribed narrow limits.
  • the level can be determined by certain devices, such as a return gas pipe, level sensor or the like.
  • the fill level is set so that the setpoint of the liquid volume is filled in a bottle filled up to the fill level. If the predetermined filling level is reached, the liquid supply is interrupted by closing a valve or the return gas pipe. The liquid that is still present between the valve and the liquid level at the time, called the follow-up volume below, flows into the bottle and leads to a higher filling level. Is the trailing volume when determining the filling level, i.e. the nominal value of the filled liquid volume is taken into account, it does not have to be removed from the bottle after the filling has been completed.
  • a back pressure filler is known from DE-C-3 019 489, in which an elastic bottle is raised on a lifting plate up to a stroke-limiting mechanical stop. In this way the distance between the base of the bottle set against a filler neck. When the bottle is lifted, it is placed in a sealed system with a seal located below the filler neck. The distance between the standing surface and the filler neck is such that the bottle is compressed in the longitudinal direction. The pressure inside the bottle is then increased and the bottle expands. The increased pressure leads to an increasing sealing force and causes the bottle to be filled gently. Depending on the length of the bottles, the mechanical stop for limiting the stroke can be adjusted.
  • a centering bell assigned to a filling kettle is known, which is arranged below a filler neck and is connected to it via an intermediate body.
  • the intermediate body ensures perfect emptying of the residual liquid from the cavity between the centering bell and filler neck if the liquid supply is interrupted.
  • the contact pressure of the bottle on the sealing element is to be ensured by means of a differential pressure chamber formed by the intermediate body.
  • a rotary filler with a lifting device by means of which the bottle neck is gripped and the mouth is raised a certain distance from the filler neck.
  • the lifting device is designed so that when possible the bottle is lowered after the filling process force-free movement is made possible.
  • a centering bell is slidably mounted on the filler neck and is moved in the direction of the filler neck when the bottle is lifted. By means of spring elements formed between the filler neck and the centering bell, a seal arranged on the centering bell is pressed onto the bottle mouth in a sealing manner.
  • a disadvantage of the previously known methods and devices is that differences in the vessel height in the case of similar vessels in particular are not taken into account or are taken into account in an unfavorable manner. Even when filling bottles of the same type, they are by no means identical. While production-related deviations are relatively small with glass bottles and the aging of the bottles has no noticeable influence on the bottle height, considerable deviations, in particular the bottle height, are possible with plastic bottles. Compensation for these deviations is of considerable importance in the case of PET bottles that can be reused for ecological reasons. By shrinking the PET bottles due to signs of aging, heat treatments, rinsing processes or the like. In addition to the height, the shape of the bottle also changes, in particular in the shoulder area between the bottle neck and the bottle body, which also affects the bottle volume.
  • the constant distance between the standing surface of the bottle and the filler neck also makes it impossible to compensate for differences in height in the case of similar vessels. Due to the increased internal pressure of the plastic bottles, these are inflated, whereby the volume is changed significantly and uncontrollably.
  • the invention is therefore based on the object of improving a method for filling a vessel with a liquid of the type mentioned at the beginning and a device for carrying out the method in that in a simple and cost-effective manner, the vessels are filled with slight deviations from the nominal value, so that a compensation of vessel height variations is made possible with vessels of the same type.
  • the trailing liquid volume is controlled as a function of the vessel height, in such a way that a larger and with a larger vessel height, a smaller volume of liquid runs on. Since the bottles with a lower container height contain too little liquid volume due to the shrinkage of the bottles, particularly in the shoulder area or the overall lower shoulder area, the liquid volume is automatically compensated for by the increase in the trailing volume. In the case of larger bottles, the trailing volume is reduced accordingly, so that the setpoint of the filled liquid is also approximated in these bottles. At a certain bottle height, the nominal amount of the liquid is obtained by adding the liquid volume filled up to the filling level and the trailing volume.
  • the mouth of the vessel before reaching the filling position, the mouth of the vessel is pressed against a seal associated with a trailing chamber formed between the mouth of the vessel and the valve, the mouth of the vessel displacing the seal in the direction of the filler neck until the final distance is reached, and thus the volume of the Follow-up chamber is changed depending on the vessel height.
  • height tolerances are automatically compensated for due to the displacement of the seal and thus the variation of the trailing chamber volume.
  • the seal is moved further towards the filler neck than with smaller bottles. Accordingly, the trailing chamber volume is smaller with larger bottles than with smaller bottles.
  • the displaceability of the seal and thus the variation of the trailing chamber volume is selected in such a way that in principle all height tolerances can be taken into account with vessels of the same type.
  • the trailing chamber is at least partially formed by a sliding sleeve arranged between the mouth of the vessel and the filler neck, at the lower end of which a sealing seal is arranged with the vessel raised in the filling position.
  • the sliding sleeve is displaced more or less in the direction of the filler neck, thus changing the trailing chamber volume.
  • the sliding sleeve is at least partially formed from an elastic material.
  • the sliding sleeve is moved in the direction of the filler neck and the part of the sliding sleeve made of elastic material becomes Deformed to adapt to the stroke of the vessel. After removing the vessel, the sliding sleeve extends back to its original size.
  • the sliding sleeve is axially movably mounted on the filler neck. In this case, the sliding sleeve is moved along the filler neck when the vessel is lifted. In order to facilitate the sealing between the filler neck and the sliding sleeve, it is advantageous if the sliding sleeve is pushed onto the filler neck from the outside.
  • the sliding sleeve is molded onto a centering bell that at least accommodates the vessel mouth.
  • the integrated design of the centering tulip and sliding sleeve considerably simplifies the construction of the device. A centering of the mouth of the vessel with respect to the filler neck is achieved by means of the centering tulip.
  • an inner seal is arranged between the filler neck and the sliding sleeve when the vessel is in the filling position. This reinforces and secures the seal between the filler neck and sliding sleeve, so that no liquid or gas is lost even with a back pressure filler.
  • the outer diameter of the outlet connection is advantageously at least somewhat larger than the inner diameter of the vessel mouth.
  • the annular surface formed above the seal of the centering bell in the region of the sliding sleeve produces a sealing force which is proportional to the pressure increase in the vessel and is directed axially to the mouth of the vessel.
  • the empty and unstable bottle is initially only lightly pressed onto the seal of the centering bell for sealing and the sealing force only increases when the bottle is preloaded, whereby the load capacity of the bottle increases due to the increase in internal pressure.
  • the filler neck is surrounded by a concentric annular space for receiving the sliding sleeve. Due to the arrangement of the seal between the filler neck and the sliding sleeve, it can also enclose the filler neck at a radial distance.
  • a seal against the annular space can be achieved when the sliding sleeve is pushed onto the filler neck.
  • annular space it is also advantageous if an opening gap to the annular space is formed in the rinsing position between the sliding sleeve and the filler neck. If the annular space has a connection opening to a flushing channel or the like, flushing the vessel with steam and / or inert gas, e.g. CO2, possible before filling. Furthermore, an at least partial evacuation and then repetition of the flushing process through the opening gap is also possible.
  • a flushing channel or the like flushing the vessel with steam and / or inert gas, e.g. CO2
  • a return gas pipe protruding therefrom is arranged coaxially with the filling nozzle.
  • a fill level probe is arranged coaxially with the return gas pipe to determine the fill level.
  • springs for guiding the centering bell are arranged on the centering bell in order to apply force to the centering bell.
  • the friction between the sliding sleeve and the Filling spout can be overcome by applying force to the centering bell.
  • the sliding sleeve can be moved without the need for an additional lowering device by the springs from the filler neck together with the centering bell.
  • the filler neck widens conically at its end in the direction of the vessel and the inside of the sliding sleeve below the filler neck conically narrows towards the vessel is.
  • FIGS. 1 and 2 show two different vessels 1 which can be raised and lowered in the directions 36 by means of a lifting device 2.
  • the lifting device 2 comprises an essentially horizontal lifting plate on which the vessel 1 with its base 3 is set up.
  • a filling position of the vessel 1 is defined by means of a stroke-limiting mechanical stop 23.
  • the lower end of the return gas tube 16 inserted into the bottle determines a filling level 8 up to which liquid is filled into the bottle 1.
  • Each bottle 1 is arranged with its base 3 at a distance 34 from the filling level 8 by the stroke limiter 23.
  • FIG. 1 shows a bottle 1 with a height 12 and in FIG. 2 a bottle 1 with a height 11.
  • a large number of bottles 1 of the same type fluctuate in their height between the smallest height 11 and the greatest height 12 with a medium height 10. In the example shown in FIGS. 1 and 2, this results in a maximum difference in vessel height 35.
  • the filling level 8 is the same for all bottles 1.
  • a follow-up volume which results for a bottle 1 with an average height 10 and which is described in connection with FIG. 3, is to be added to the liquid volume filled up to the filling level 8.
  • follow-up volume and liquid volume filled up to the filling level 8 result in the target filling quantity for an average bottle.
  • the substantially cylindrical bottle body 37 are for both bottles in essentially identical, so that the liquid volumes 42 and 43 filled therein are essentially the same size.
  • a shoulder section 38 or 39 arranged between the bottle neck 40 or 41 and the bottle body 37 exhibits the greatest deviations in the case of bottles of the same type.
  • the filling level 8 is located within the conical shoulder sections 38 and 39.
  • the liquid volumes 44 and 45 are different, the liquid volume 44 being greater than the liquid volume 45, also due to the cylindrical lower region of the shoulder section 38, which is not present in the shoulder section 39 .
  • the trailing volume (dotted) is smaller than that of the bottle 1 from FIG. 2 with the bottle height 11. Due to the larger trailing volume, the bottle 1 from FIG. 2 compensates for the lower liquid volume 45 reachable in the shoulder section 39. Essentially, the liquid volumes 44 and 45 with the corresponding trailing volumes result in a liquid volume which, together with the essentially identical liquid volumes 42 and 43 of the bottle body 37, results in the desired filling quantity of the bottles 1.
