Definitions

  • the invention relates to a device for filling an adjustable amount (M) of a medium according to the preamble of claim 1.
  • the medium is, for example, liquids.
  • Bottling plants are usually operated according to the time-pressure method.
  • the opening duration of a filling valve is calculated as a function of the amount to be filled and in dependence on a measured liquid pressure.
  • the properties of the medium are also dependent on e.g. from the temperature. Such parameters require a correction of the filling time.
  • From the DE 41 17 287 A1 is a generic device for filling an adjustable amount of a medium known.
  • the time for filling at a master filling station is measured by means of a flow meter.
  • the filling of trailing slave filling stations is controlled, whereby additionally a correction value can be used which takes into account changes of the influencing variables on the flow velocity.
  • An adjustable restrictor ensures identical filling conditions at all filling points.
  • the idea is that at a known pressure (p k ) depending on the flow (D), the filling of a set (M k ) is performed, and that from this and from the time required for it (t k ), a correction factor (K) is calculated , In this correction factor (K), the dependencies of the filling time (t) then depend on the filling properties of the medium. As long as the medium does not change, for example by keeping the temperature of the medium constant remains, with this correction factor (K), the filling time (t) depending on the amount to be filled (M) and the pressure (p) can be calculated.
  • the filling station is operated in the normal operation with the time-pressure method, wherein for the necessary correction factor (K), which responds to the filling properties of the medium, in connection with a flow meter, a special filling is made.
  • K necessary correction factor
  • the bottling plant has at least two filling points. At the first filling point is the flowmeter, which allows the calculation of the correction factor (K). This correction factor (K) then uses the times (t) for the further fillings at this first filling point. At the same time, this factor (K) also serves to calculate the time at the at least second filling point. Thus, only one flow meter is required, but it can be operated multiple bottling.
  • control unit is designed such that the flow (D) of the medium is measured only in the case that the filling time (t) is greater than the minimum filling time (t min ) of the flowmeter. For filling times (t), which is shorter than the minimum filling time (t min ), the measuring uncertainty of the flowmeter is too high, so in these cases, the flow should not be measured.
  • Fig. 1 shows the course of the procedure.
  • the correction factor K is calculated, which results in a filling of an amount M k via the measurement of the flow rate D k and the time t k , until the amount M k is filled, at the measured pressure p k .
  • the following fillings are performed using the correction factor K, which must be determined again only when the filling characteristics of the medium have changed.
  • the correction factor K can also be determined at each filling at the first filling point 1. This is useful if the medium can not or should not be monitored directly, and if, for example, several filling points 1, 2 work with this correction factor K, so that always a reliable value must be given.
  • Fig. 2 is the block diagram of a bottling plant with two filling points 1, 2.
  • the flow meter 5 At the first filling point 1 is the flow meter 5.
  • the control unit 6 is further connected to the pressure gauges 3 of the first 1 and the second filling point 2.
  • the correction factor K is determined by the control unit 6 at a first filling and used for the subsequent bottling, in dependence on the pressure p and the amount to be filled M the medium to calculate the time t, the valves 8 must be opened to fill the amount M.
