Definitions

  • the invention relates to a method and a device for influencing the filling quantity when filling liquids in bottles, in particular CO2-containing liquids in the counterpressure method.
  • a mechanical adjustment is known from a container filling element with a liftable return air pipe (DE 28 08 345).
  • This container filling element for gaseous liquids has a vertically movable return air tube which is mounted in the filling element and which can be brought into an upper position by means of a lifting drive and for filling up to a lower position which is immersed in the container to the level of the maximum filling level.
  • the lifting drive has a pinion which is rotatably mounted in the filler organ housing and meshes on a rack toothing of the return air tube and which is arranged in a return air space of the filler element, in which the upper end of the return air tube also lies.
  • a disadvantage here is the entire mechanical structure, which must be operated for each individual filling element in order to carry out the function with each container change, that is to say the lifting of the return air pipe in order to be able to attach a container to the filling element and the lowering of the filling element to complete the filling process to end with the appropriate fill level.
  • a method and an arrangement for adjusting the filling height in bottles when filling on height filling machines with several filling elements
  • the components of the filling elements required for the filling height adjustment are height adjustable by a common adjustment device.
  • the setting device is indirectly controlled by signals or by data which are determined by a data processing device by processing parameters. Such parameters are, for example, the reference temperature of the bottles, the filling temperature of the liquid and the like. The like.
  • the adjustment device consists of an adjustment of the upper part of the filling machine.
  • the height is adjusted by a stepper motor, which is controlled by the data processing device.
  • the disadvantage of this fill level adjustment is the great electrical and, in addition, the mechanical complexity of the method and the arrangement.
  • the filling valves each have a liquid valve which can be closed accordingly by an electronic control pulse emanating from a filling level measuring probe, the supply voltage for the filling valve electronics being supplied via a common transmission element. Signals are generated based on existing global parameters for the product or the bottles to be filled, and then, depending on the internally measured fill level, the closing time is corrected simultaneously in the form of a time delay or time certificate.
  • An electronic filling valve is a requirement for this switching method.
  • a continuously operating rotary filling machine (EP 0 179 975) is known for this purpose, in which pneumatic bottle lifters are provided and the filling taps are equipped with two-part, telescopic filling bells.
  • the upward coaxial movement of the lower centering and sealing element is limited to a minimum force so as not to damage the containers to be filled.
  • this force is not sufficient to create the required tightness at a filling opening of the container in order to initiate the filling process.
  • the tightness with the filling bell is then optimized by introducing liquid into a chamber which is enclosed between the upper fixed element and the movable lower element, thus increasing the counterforce at the filling opening of the container.
  • the containers to be filled consist of bottles with a neck collar
  • a device U 87 09 382 for centering bottles and the like.
  • the incoming bottles are countered by a gripper device that can be placed under the neck collar Filling and wear machine to move.
  • the gripper device has a fork-shaped centering opening for the bottle neck and, in addition to this, a gripper-free holding surface which counteracts the centrifugal force of the bottles.
  • the invention has for its object to adjust a level of the filling level of a CO2-containing liquid in bottles to be filled when filling in a bottle filling machine to ensure a constant nominal amount.
  • the main advantage of the solution according to the invention is that a central change in the filling level of all bottles to be filled is achieved by the method according to the invention and the associated devices, and the filling quantities in the bottles can also be changed by the changed filling level.
  • the filling quantity in the bottles can be adjusted so that it corresponds to the nominal filling quantity. Deviations from the nominal filling quantity caused by e.g. B. temperature fluctuations of the contents and or arise from foam formation, can be compensated. All that is necessary is to change the height position of the return path of the return gas escaping from the bottle centrally. This change is achieved in the invention in that the bottles to be filled are positioned differently in relation to the return gas opening.
  • the invention will be explained in more detail below using an exemplary embodiment.
  • the exemplary embodiment relates to a filling of liquids in PET bottles.
  • a bottle is placed on each filling element.
  • the bottles in the example are plastic bottles, for example PET bottles, which have a neck collar on the bottle neck.
  • the bottle is first centered and then on a vertically movable circular sealing element with a seal from below created.
  • the bottle is moved vertically by a lifting device up to a height position set at this.
  • only the sealing element lies on the bottle mouthpiece with its own weight or loaded by a slightly prestressed spring, ie the contact pressure of the sealing element is very low.
  • the bottle is evacuated if necessary, but the sealing element must be locked, and then biased.
  • the bottle sucks on the sealing element.
  • the differential pressure created by the circular surface of the sealing element acts and seals the bottle sufficiently. If the pressure in the bottle is equal to the pressure above the liquid in the filling tank, the liquid valve opens and the bottle is filled.
  • the prestressing gas in the bottle escapes into the filling tank through a return gas opening in the return gas pipe.
  • the filling process is ended when the liquid level closes the return gas opening of a return gas pipe. No more return gas can escape from the bottle through the return gas pipe into the filling tank and the filling process is ended by closing the liquid outlet.
  • the pressure is influenced by the size of the differential pressure area between the piston and the bottle mouth.
  • the bottle is then relieved and discharged.
  • the filling level of the liquid in the bottle determines the filling quantity.
  • the filling level is determined by the height position of the return flow path of the return gas escaping from the bottle in relation to the bottle. This height position is adjusted and the filling level and the filling quantity are thereby influenced.
  • the height position is adjusted by a stroke adjustment and limitation of the bottle with respect to the height position of the return flow path.
  • the associated device for influencing the filling quantity when filling liquids in bottles, in particular CO2-containing liquids in the counter-pressure process consists of a filling machine with a filling tank, preferably an annular channel 1, on which filling elements are arranged.
  • the liquid 2 to be filled is located in the annular channel 1 and above it in a clamping gas chamber 3 is the clamping gas, which is under a pressure of, for example, 3 to 6 bar.
  • the filling elements arranged on the ring channel 1 have a filling organ housing 4 with a liquid outlet 5 and a liquid valve 6.
  • a return gas pipe 7 which has a return gas opening 8 at the bottom and which communicates with the upper end with the clamping gas chamber 3 and in its upper region is provided with a shut-off valve 9.
  • a conical liquid guide body 10 which is adapted to the shape of the liquid outlet 5.
  • the gas line 11 opens from the biasing valve 12 and relief valve 13 arranged in the filling organ housing 4.
  • the gas line 11 opens above a sealing element which consists of an annular piston 14 with a seal 15 and a sealing lip 16 sealing the bottle.
  • the piston 14 is arranged in the filling organ housing 4 so as to be vertically movable and, with its upper annular surface, generates a differential pressure depending on the pressure in the liquid outlet 5, which acts on the bottle mouth of a supplied and applied bottle and seals it against the attachment lip 16.
  • the bottles are fed to the filling machine via known devices.
  • the bottles are fed to the filling element by lifting by a lifting element, which for PET bottles consists of a fork 17.
  • the fork 17 reaches under the neck collar of the bottle and leads it to the sealing element on the filling element.
  • the fork 17 is arranged on a pneumatic cylinder 18 which is fastened on a piston rod 19 in a manner fixed against relative rotation and height (hanging pressure cylinder).
  • the piston rod 19 is fixed on a connecting ring 20 and includes a line 21 with an opening for the supply of compressed air.
  • the vertical movement of the pneumatic cylinder 18 takes place upwards through compressed air up to an adjustable stop and downwards through a roller 22 with a control cam 23 arranged on the pneumatic cylinder 18.
  • the piston rod 19 is still mounted in a holder 24 on its upper part.
  • the connecting ring 20 and the holder 24 are part of the carousel of the filling machine.
  • the adjustable stop consists of an adjusting element 25, which is designed to be rotationally symmetrical and has a toothing on its circumference into which a toothed ring 27 which adjusts all the stops engages.
  • the vertical movement of the pneumatic cylinder 18 upwards can, however, also be effected by the roller 22.
  • the roller 22 is guided on the control cam 23, which, however, is designed to be continuous and height-adjustable in this mode of operation.
  • the control curve 23 limits the pneumatic cylinder 18 moved upwards in its height position and at the same time moves the pneumatic cylinder 18 with the fork 17 downwards to remove the filled bottles.
  • the device works as follows:
  • the working cycles when filling liquids in bottles, in the example a CO2-containing liquid in PET bottles, are basically the same as known processes.
  • the evacuation, prestressing, filling and unloading is carried out as in known filling machines.
  • the feeding of the bottles to the filling elements, the sealing and the control of the filling process is changed.
  • an empty bottle is gripped by the fork 17 of the lifting member under the neck collar and moved upward.
  • the movement takes place in that the pneumatic cylinder 18 is pressurized with compressed air via the compressed air line 21 and the control cam 23 releases the roller 22.
  • the bottle moves in its height movement through a centering opening and lies against the attachment lip 16.
  • the piston 14 of the sealing element which is vertically movable in the filling organ housing 4, is in its lowermost position and is guided with the bottle upwards.
  • the sealing lip 16 is loosely loaded by the weight of the sealing element or by a slightly preloaded spring on the bottle mouth.
  • tensioning gas is passed through the gas line 11 into the liquid outlet 5 and into the bottle.
  • the differential area of the annular piston 14 and the inside diameter of the bottle mouth create a differential pressure, by means of which the piston 14 of the sealing element is pressed down. Increased by the pressure on the lip 16, the bottle is thus centered and sealed.
  • the filling takes place, which is also ended in a known manner by closing the return gas opening 8 by the rising liquid.
  • the completion of the filling process is controlled by the invention in that the height position of the bottle to the return gas opening 8 in the return gas pipe 7 can be adjusted centrally.
  • the adjustment is made by a stop on the lifting element.
  • the stroke of the fork 17 is limited by the stop, and thus the height position of the bottle to the return gas opening 8 of the return gas pipe 7, which is immobile after the closing of the liquid valve 6.
  • the stop is centrally adjustable.
  • the adjustment is carried out by changing the height of the adjusting element 25.
  • the adjusting element 25 is rotated by the ring gear 28 and its height is changed by the fine thread on the piston rod 19.
  • the adjusting element 25 Since the fine thread is self-locking, the adjusting element 25 remains in its set height. The bottle can only be inserted into the filling element through the fork 17 up to the fixed height position.
  • control cam 23 which is height-adjustable and continuous for this purpose, effects an upward stroke limitation by the roller 22. Since the roller 22 is attached to the pneumatic cylinder, it limits the stroke of the fork 17 and thus the height position of the bottle.
  • the stop that limits the height of the pneumatic cylinder 18 was adjustable in height. But it is also possible to fix the height of the stop firmly and thus limit the pneumatic cylinder 18 in its vertical movement.
  • the change in the height position of the return flow path of the return gas escaping from the bottles takes place here by the height adjustment of the filling kettle with the filling elements.
