Definitions

  • the invention relates to a method for controlling beverage filling systems and beverage filling systems, in particular with filling machines, which have a throughput of more than 10,000 containers per hour, in particular a throughput of more than 50,000 containers per hour.
  • beverage filling systems are e.g. Round filling machines with the assigned product feed.
  • the regulation of the supply of drinks to the product container e.g. a ring bowl or a distributor ring of a filling machine is not without its problems. Difficulties can arise when the operating state of such a filling machine changes, in particular when starting up, when stopping and when changing the respective output (container / h).
  • the beverage supply is regulated by means of level sensors and in the case of a black one, i.e. Distribution channel completely filled with product via a pressure sensor as a guide signal.
  • the disadvantage here is that the regulation of the beverage supply only reacts when the level in the ring kettle or the pressure in the product feed / product line to the filling valves changes due to the change in the operating state of the filling machine, for example by the start of the delivery of drink from the ring kettle changes to the containers to be filled. There is a first loss of time here, which has an adverse effect on the readjustment.
  • This second loss of time is particularly great in the case of high-performance systems (throughput up to 70 m 3 / h) with often very long product feed lines and is particularly disruptive due to the particularly high unit output (container / h) in these systems.
  • a method and a beverage filling system according to the alternative of the preamble of claims 1 and 8, wherein the signals of the flow meters of all filling elements are added to a current volume flow signal are from the US 6,378,575 B1 known.
  • a method and a beverage filling system according to the alternative of the preamble of claims 1 and 8, wherein the speed of the filling machine is currently measured and a current volume flow signal is calculated from the measured speed value taking into account the number of filling elements and the volume of a container to be filled JP S62 168896 A known.
  • this object is achieved by a method having the features of claim 1.
  • the object is further achieved by a beverage filling system with the features of claim 8.
  • Advantageous developments of the invention are the subject of the associated dependent claims.
  • Advantageous embodiments of the invention are also disclosed in the description and in the drawing.
  • the product quantities supplied to the containers via the filling valves of a filling machine are recorded in each filling element.
  • These signals from the flow meters of all filling elements of the filling machine are added up to a current volume flow signal.
  • the speed of the filling machine in particular the rotational speed, can currently be measured and a current volume flow signal can be calculated from the measured speed value, taking into account the number of filling elements of the filling machine and the volume (filling volume) of a container, in particular according to the formula : Number of filling elements of the filling machine x liquid volume of a container x speed of the filling machine.
  • the individual filling elements of the filling machine preferably fill a certain volume of liquid into each individual container, regardless of the filling height resulting therefrom.
  • one filling element after the other starts the filling process. Since the acceleration and / or deceleration ramps of the speed of the filling machine (speed curve over time) are stored, the requirement for filling material can be determined over time essentially before or even when the filling begins. In this simple embodiment of the present invention, provision is therefore made to control and / or regulate the product supply already at the start of filling. Preferably in such a way that the expected changes in the filling material requirement are also taken into account during the changes in the operating state of the filling machine.
  • the current volume flow signal measured or calculated in the alternatives mentioned above is used to derive a control signal for the product supply.
  • This volume flow signal can be transmitted directly to the control loop for the central product supply.
  • the product supply is then regulated accordingly depending on the current volume flow signal.
  • control valve in the product line can thus, in conjunction with a flow meter also installed there, begin to feed the filling material in good time, which is why the valve seat is opened early, for example.
  • the subsequent delivery takes place before this process would be triggered by a falling level or a falling pressure.
  • the level and pressure in the start-up phase or when changing performance can be kept constant to an extent not previously possible.
  • an offset value for a basic delivery quantity of filling material can be subtracted or added from the sum of the flow values supplied by the filling point MID, e.g. as part of a level correction.
  • a software combination with any additional pressure or level control may be used.
  • the product supply is additionally regulated as a function of the signals of at least one level sensor arranged in the product container. This means that not only the current volume flow signal is taken into account for the volume flow to be supplied by the product supply, but also the fill level in the product container, which can advantageously be used in such a way that a fill level in the product container that deviates from the nominal fill level is immediately compensated for by a corresponding readjustment of the product supply can.
  • “Regulation of the product supply” generally means the regulation or control of at least one product control valve arranged in a product supply line and / or at least one product feed pump assigned to the product supply. These two components can be controlled or regulated either alternatively or together by a control of the beverage filling system.
  • the beverage filling system contains a round filling machine.
  • the current speed of the rotary filling machine is measured, the speed curve of the filling machine being saved when starting or braking.
  • a ramp of the speed curve over the time range of starting or braking is thus stored.
  • the amount of the continuously decreasing filled volume flow is thus calculated in advance from the actual speed, the current volume flow signal and the stored speed curve.
  • the product supply can thus be regulated immediately in accordance with the decreasing volume flow when the filling machine is braked, without the filling level in the product container rising above the desired filling level. In this way, this gradual shutdown of the product quantity supplied to the product container can take place simultaneously with the braking of the filling machine at the end of the product.
  • the volume flow to be expected when starting up the filling machine can be determined in advance, and from the stored temporal speed curve of the filling machine when starting up, possibly from the target speed of the filling machine, from the number of filling elements and from the target filling quantity per container filling.
  • the product supply can be adjusted to the expected volume flow as soon as the filling machine is started up.
  • the control of the beverage system can thus predict how the volume flow requirement of the filling machine increases with the machine starting up. It can thus regulate the product supply accordingly at least at the same time, so that there is no time delay between the increasing volume flow requirement of the filling machine and the quantity of product supplied.
  • the actual speed of the filling machine is compared with the target speed in accordance with the stored finished speed curves when starting and braking, and a correction signal for regulating the product supply is derived from the comparison signal.
  • the product supply is then controlled or regulated depending on the correction signal.
  • a deviation of the current speed of the filling machine from a stored speed curve can be detected and taken into account in the control or regulation of the product supply.
  • the amount of product supplied then corresponds exactly to the filled product volume flow when filling the containers, even if the filling machine does not start or slow down exactly according to the stored time profile.
  • the stored temporal speed profiles or speed ramps are constantly updated by current values of the speed profiles when starting and starting the machine, as a result of which the stored speed profiles are always up-to-date.
  • a product feed flow meter for generating an actual feed volume flow signal is preferably arranged in the product feed and the actual feed volume flow signal is compared with the current volume flow signal or an expected volume flow when starting / braking the filling machine. Depending on the comparison result, a correction signal for regulating the product supply is then derived.
  • target speed curves are always used as a reference during ongoing operation or when the speed changes and compared with the current speed curves, the product supply being adjusted accordingly if there are deviations from the reference values.
  • the containers are preferably filled volumetrically, ie exactly the same amount of product is always filled in each container regardless of the fill level. This allows a simpler calculation of the actual volume flow in the case of an arithmetical determination of the volume flow signal in an alternative of the invention.
  • the invention also relates to a beverage filling system according to claim 8.
  • This beverage system is able to match the product flow supplied to the product container, in particular ring bowl, via the product supply in the volume flow precisely dispensed into the container.
  • an offset value can be reserved here to take into account the operational conditions of the filling machine, for example to slowly adjust a fill level in the product container to a setpoint.
  • At least one fill level sensor is preferably arranged in the product container and the product control module is designed to regulate the product feed also as a function of a fill level signal from the fill level sensor.
  • the product supply is not controlled solely on the basis of the current volume flow signal, but also as a function of the fill level, which means that the fill level in the product container can always be kept within a narrowly defined, predetermined target fill level range, which increases the operational reliability of the filling machine is beneficial.
  • the flow meters of the filling elements are preferably formed by magnetic inductive flow meters (MID), which are able to deliver a very exact volumetric value of the filling quantity when filling each container.
  • MID magnetic inductive flow meters
  • a product feed flow meter for generating an actual feed volume flow signal is arranged in the product feed, the signal being fed into the product control module in order to derive a correction signal for regulating the product feed.
  • the product flow supplied can be continuously compared with the current volume flow signal, and the product supply can be readjusted accordingly without delay in order to maintain a constant fill level in the product container.
  • the advantage of the present invention is that an almost instantaneous control of the product supply is possible, which leads to a very constant fill level in the product container, in particular also during changes in the operating state of the filling machine, e.g. with changing operating speeds or when starting up and braking (end of operation) of the filling machine.
  • the beverage filling system 10 is described below with reference to all of them Figures 1 to 3 describe.
  • the beverage filling system 10 contains a round filling machine 12 which has an annular bowl 14 on its circumference as a product container.
  • the round filling machine 12 also has a multiplicity of filling elements 16, each of which has a filling valve 32 for filling a container 18, for example a bottle.
  • the ring bowl is arranged radially on the inside of the filling elements 16.
  • the ring bowl feeds all filling elements 16 of the filling machine 12 for filling containers 18.
  • the ring bowl 14 is connected via a product feed line 21 to a product feed 20 which contains a product control valve 22 and a product feed pump 24.
  • the product supply line 21 is also preferably connected to an extremely large buffer tank of a mixer, which is not shown in the drawing and which does not belong to the beverage filling system 10.
  • the beverage filling system 10 is controlled by a central control 26, which has a memory 28, for storing time-related speed curves of the filling machine as well as for storing other parameters, such as the number of filling elements on the filling machine 12, the volume of the container 18 to be filled and target values or setpoint ranges.
  • the controller 26 also has a product control module 30, which is responsible for regulating the product feed 20, through which the product is fed to the ring bowl 14.
  • each filling element 16 also contains a flow meter 34, both of which are connected to the controller 26.
  • the beverage system 10 also contains a fill level sensor 36, which is connected to the controller 26, so that the controller 26 constantly receives a signal about the current fill level in the ring bowl 14.
  • a product flow meter 38 is also arranged in the product feed line 21 in order to be able to volumetrically record the amount of product fed to the ring bowl 14 in real time.
  • the containers 18 are fed to the filling machine 12 via a container feed 40 and discharged via a container discharge 42, usually by means of transfer gyros known per se.
  • the beverage system 10 shown works as follows: In a first possible procedure, the controller 26 can record the rotational speed of the round filling machine 12, whereby it can generate a current volume flow signal by the current rotational speed of the filling machine, the filling volume of the containers 18 to be filled and the number of filling elements 16, which signal can then be used to control the product supply 20, that is, the product control valve 22 or the product feed pump 24 can be used, in particular in order to be able to set the product quantity to be fed to the ring bowl 14 at the same level as the product quantity just filled (corresponding to the current volume flow signal), so that the fill level in the ring bowl 14 remains constant ,
  • the signals from the flow meters 14 of all the filling elements 16 of the filling machine 12 are added to a current volume flow signal in the product control module 30 of the controller 26 and the product supply 20, i.e. the product control valve 22 and / or the product feed pump 24 are controlled in such a way that the product quantity supplied corresponds to the added values of the flow meters 34 of all filling elements 16, i.e. the current volume flow signal.
  • the product feed 20 can be adjusted in real time almost without delay to the volume flow requirement when filling the filling machine 12.
  • the regulation of the product supply can then take place in such a way that not only the same amount of product that is currently being dispensed into the containers 18 is supplied, but this value can also be increased or decreased by an offset, e.g. in order to adapt an actual fill level in the ring bowl 14 to a desired fill level, i.e. to lower or raise the level.
  • This offset value can e.g. be used to regulate the product supply until the actual fill level determined by means of the fill level probe 36 has been adjusted to a desired fill level stored in the memory 28.
  • the round filling machine 12 is shown only very schematically in the figures.
  • a round filling machine 12 has many more filling elements, e.g. 100 filling elements distributed around their circumference.
  • the ring bowl 14 preferably runs inwards to the filling elements, so that the volume flow that flows from the ring bowl 14 to the filling element 16 is increased by the centrifugal force.
  • the ring bowl 14 can also run over the filling elements 16.
