Definitions

  • the invention relates to a method for controlling a filling system according to the preamble of claim 1.
  • a control device determines a control value which corresponds to the filling time on the basis of the measured value supplied by the flow meter of the master filling station.
  • the control device causes by appropriate control signals opening a liquid valve of the filling element of the associated slave filling station.
  • remote prior art still includes a device for filling containers, as shown in the DE 690 00 764 T2 is described.
  • a weighing member is provided to send opening or closing signals to an outflow control member in response to a weight measured by the weighing member.
  • the possibility is addressed, with a faulty weighing organ to make a time control function of an average value of effective filling times at other filler.
  • For aseptic filling plants are generally known that form within a housing closed to the outside, with filtered sterile air clean room or clean room area through which a transport route for the containers or bottles reaches, then in which within the clean room area a rinser, a Filling machine and a capper are provided in succession in the conveying direction.
  • this clean-room area is surrounded by a security area in which, inter alia, locks or passages for supplying the empty containers to be filled or for discharging the filled and closed containers are provided.
  • filling elements for filling bottles or the like containers with a liquid filling material in particular for filling bottles with drinks in different designs are known, even in embodiments as filling elements for a volume-controlled filling (volumetric filling).
  • a flow measuring device is provided in a liquid line between a source of the liquid filling material (eg storage container or boiler) and the respective filling element, which indicates a completion of the filling process, ie. H. the closing of the liquid valve, inducing measuring or control signal to a central control device (computer) of the filling machine supplies.
  • the invention achieves this by a method for controlling a filling system having the features of patent claim 1.
  • a plant according to the invention can continue to operate on a filling element despite a defect in a flow meter, without having to repair the defective flow meter immediately.
  • a relatively reliable filling of the containers can also take place with the defective first filling element.
  • the current conditions are taken into account, especially in the vicinity of the defective filling element, so that deviations in the desired filling only are low, and thus the appropriate requirements regarding the allowable deviations of the quantities can be met even in case of failure.
  • the filling elements are attached to a large rotating rotor, which can also carry a tank with the material to be filled. Since the level in the interior of this tank fluctuates very strongly over time and even large spatial deviations occur in the interior of the tank during operation, the applied filling pressure is subject to the filling elements depending on their position and the respective temporal conditions very strong fluctuations. Similar problems occur when each filling element carries its own container for the contents.
  • the filling element with the defective flow meter in the direction of rotation preceding filling element for determining the necessary opening time, since this due to the spatial proximity of the feeds to the filling tank is subject to very similar conditions as the defective element. In this way, the required opening time is relatively accurate to use for the defective filling element.
  • valve opening signal of the second filling element delayed by the necessary, dependent on the rotor speed rotation time to a filling position, is applied to the first filling element.
  • the method is particularly advantageous in the case of a defect of the flow measuring device of the first filling element to apply.
  • the correction factor is determined by evaluating the stored opening times of the first and the second filling element.
  • At least one central computer or control unit is provided. Since the use of such control units is also known on container treatment machines, further explanations to these units are not necessary. On a representation in the figures was also omitted.
  • the invention also relates to a control unit for carrying out the method according to the invention and to a filling system with a corresponding control unit.
  • FIG. 1 An aseptic filling line, generally designated 1, for use with the controller of the invention is disclosed in U.S.P. FIG. 1 shown in more detail.
  • Bottles 6 or the like Containers are transported by means of a conveyor on the one hand through a lock 7 in the interior of the housing 5 and initially from the rinser 2 before a rinser 2, a filling system 3 and a capper 4 in a closed housing the filling rinsed once again and disinfected. Following this, the bottles 6 pass through the filling system 3 and are provided after completion of filling in the capper 4 with a closure. Following this, the bottles 6 pass through another lock 8, through which they leave the germ-free environment inside the aseptic housing 5 again.
  • the filling machine 3 has a rotating rotor 10, which rotates about the machine vertical axis 11 by a drive system not shown in detail.
  • the bottles 6 are taken after leaving the rinser 2 from the rotor 10 and run with this on a partial circular path through the filling machine.
  • filling elements 11, in particular a first filling element 12 or a second filling element 13, are arranged.
  • the bottles run under the filling opening of the filling elements 12, 13 at the same rotational speed as the rotor 10 through the filling machine 3.
  • the filling elements 12, 13 are opened and the material to be filled enters the bottles 6.
  • the filling elements 12, 13 are closed again and the bottles 6 are fed from the filling machine 3 to the capper 4.
  • Analog runs also the filling of other containers, such as cans, multi-chamber bottles, etc.
  • FIG. 2 The structure of a filling element 12, 13 is in FIG. 2 shown in more detail.
  • Such a filling element 12, 13 has at its lower end to a filling valve 14 which can be opened and closed, for example via a rod of an electromechanical switching element 15.
  • a liquid container 16 is the material to be filled, for example, a drink or a liquid medicine.
  • the level 17 of the reservoir 16 depends on a number of factors, for example, the time since the last filling or the flow rate of the feed system, not shown, which supplies the liquid to be filled to the filling machine 3. Due to the constantly changing liquid level 17, the filling pressure at the filling valve 14 is subject to strong fluctuations, so that the flow rate and thus the time required to reach a certain amount in the underlying bottle, also varies. In order to fill in spite of this fluctuation always a constant capacity in the bottles 6, a magnetically inductive flow measuring device 18 is provided which can determine the amount of liquid passing through the valve 14 exactly.
  • the opening time of the front in the direction of rotation filling element 13 is measured. This is the time that elapses from the opening of the filling valve of the filling element 13 until it closes, this time being based on which is determined by means of the there still intact flow measuring device.
  • the filling valve of the filling element 12 is opened for the same period of time, wherein the start pulse is given by the time delay, which requires the filling element 12 to be rotated by the rotor 10 to the same starting position at which previously the filling valve 13 on Start of filling has found.
  • both filling valves are open for an overlapping period, since the start pulse and the stop pulse of the intact valve 13 by the corresponding required, dependent on the rotational speed of the rotor 10 rotation time, delayed passed to the defective first filling element 12 becomes.
  • the defective first filling element 12 and the intact second filling element 13 are in spatial proximity in the machine, the conditions prevailing there are relatively similar, so that the method described above leads to a satisfactory filling even with the defective filling element 12.
  • the replacement of the defective flow measuring device can then take place at the next regular standstill of the system 1, since a complete cleaning and disinfection of the interior of the housing 5 must be made anyway anyway.
  • the opening times of further expediently anticipatory filling elements can be included in the calculation of the opening time for the defective filling element 12.
  • Static parameters for correcting the opening time are also possible, for example due to generally different flow rates of the individual filling elements due to structural conditions or a general Lengthening or shortening of the opening time by a certain amount in order to tend to overfill or underfill the container, whichever is more appropriate in terms of plant operation.
  • the invention is of course not limited to the above embodiment, but can be modified in many ways, without departing from the spirit.
  • the arrangement of the mentioned machines and the addition of other types can be varied.
  • the invention can also be used in principle in conventional non-aseptic filling systems to minimize downtime.
