Definitions

  • the invention relates to a method for safe filling valve-controlled filling systems according to the preamble of claim 1 and as from DE 101 49 473 A1 known.
  • Valve-controlled filling systems are used in various industrial sectors to fill liquid products into special containers, usually bottles.
  • the problem here is often the foaming during the filling process. If the filling product is a soapy liquid, for example hair shampoo, the foaming caused by air bubbles during filling can easily cause the shampoo bottle to overflow during the filling process. Such spillover at a single filling station can result in the stoppage of the entire bottling plant. Depending on the amount of product overflow, extensive cleaning measures are necessary.
  • the amount of product to be filled in each filling process is often measured with flowmeters (eg Dosimass, Dosimag from Endress + Hauser) and adjusted via a dosing control.
  • flowmeters eg Dosimass, Dosimag from Endress + Hauser
  • the object of the invention is to provide a method for safe filling in valve-controlled filling systems, which does not have the disadvantages mentioned above, in particular reliably prevents the overflow during the filling process due to bubble formation and which is easy and inexpensive to implement.
  • the essential idea of the invention is that the formation of air bubbles in the filling product, which cause the overflow during the filling process, quickly and easily by the evaluation of multiple flow values D (ti), at times when there should be a constant flow at the filling station concerned detect.
  • the flow meters may, for. B. Coriolis or magnetic inductive flow meters.
  • the invention is particularly suitable for fast filling operations in which the time between opening and closing of the filling valve is less than 1-5 seconds.
  • the pulses which are output at the pulse output of the flowmeters are used to determine the current flow value.
  • Fig. 1 typical bottling plant in a schematic representation
  • Fig. 2 Filling curve at a filling station of the filling plants
  • FIG. 3 simplified filling curve after Fig. 2
  • Fig. 1 is a typical bottling plant as used in various industries.
  • the liquid filling product P (hair shampoo) is provided in a storage container 40.
  • the reservoir 40 is connected via a central supply line 50 with the individual filling stations ap which are designated as line 1 to line 16. For clarity, only two filling station a and p are provided with reference numerals.
  • Each filling station has a flow meter 52 and a filling valve 54. Via valve tips 56, the filling product AP is filled into the filling container 60, here shampoo bottles.
  • the filling containers 60a to 60p together are guided via a conveyor belt 70 to the individual filling stations.
  • the flow measuring devices 52 and the filling valves 54 are connected to a dosing control unit 10 via signal lines, 16 control signal lines SSL1-SSL16 and 16 measuring signal lines MSL1-MSL16.
  • the metering control unit 10 is constructed in a modular manner. It consists of a power supply unit, a central processing unit, Profibus DP slave unit, a digital pulse input unit (16-fold), a digital pulse output unit (16-fold 24V, 0.5 A) and a 4-20 mA - Unit (4-way AI, 2-fold AO)
  • the metering control unit 10 is connected to a central controller 20.
  • the communication between the Dosier horrungsaku 10 and the central controller 20 is carried out according to the Profibus DP standard, the Dosier horrungsaku 10 acts as a Profibus DP slave and the controller 20 as a Profibus DP master.
  • the controller 20 controls the entire supply and discharge of the filling container 60 to the individual filling stations a-p. The entire filling cycle for every 16 filling containers takes about 5 seconds.
  • the metering control unit 10 is further connected to a local display unit 30, which is designed as a touchscreen, via which the configuration of the bottling plant takes place.
  • Constant filling conditions are only obtained if the top pressure KP in the feed tank 40 is kept constant.
  • a pressure gauge 46 is provided on the reservoir 40, which measures the head pressure KP in the container 40. Via a compressed air supply line 42, in which a valve 44 is provided, the head pressure KP can be adjusted. The corresponding control of the head pressure also takes place via the metering control unit 10.
  • the current head pressure is transmitted as a 4-20 mA signal via the measurement signal line MSL 17 to the metering control unit 10.
  • the valve 44 is actuated by the metering control unit 10 in order to thereby keep the head pressure KP in the container 40 constant.
  • Fig. 2 is a filling curve as it typically occurs at each of the filling stations ap.
  • the flow rate at one of the filling tips is plotted as a function of time.
  • the desired filling quantity F is predetermined during the start-up of the filling installation and stored in the metering control unit 10. According to the Filling capacity F, the filling valve is activated at each filling station.
  • T2 filling valve 54a is fully open.
  • T3 command from the dosing control unit 10 to the filling valve 54a Close valve, since the filling amount is achieved in consideration of the follow-up amount.
  • T4 filling valve 54a is closed.
  • the filling quantity F of the filling product AP filled into the filling container 60 corresponds in principle to the area under the curve between the times T 1 and T 4 (about 0.5 sec).
  • Fig. 3 is the filling curve according to Fig. 2 once more simplified.
  • the flow remains approximately constant between times T2 and T3.
  • This time range is divided into several time intervals t1 to tn.
  • the entire filling process takes less than 1 second.
  • the length of the time intervals t1 to tn can be selected between approximately 10-100 msec.
  • the current flow value D (t i ) can be specified.
  • the values D (t i ) are checked for significant deviations. If a significant change is detected, the valve 44 is closed at the respective filling station before the time T3. Significant deviations usually indicate foaming. By closing the respective filling valve overflow of the filling container is avoided.
  • the invention assumes that between the times T2 and T3, the flow rate is approximately constant.
  • the mean value of the flow in this time range can be obtained, for example, with a moving averaging from the values D (t i ).
  • the tolerance limit is approx. +/- 5%. It is application-specific adjustable.
  • the inventive method is characterized mainly by its simplicity and by its speed. With the method according to the invention a safe filling is possible even with foaming filling products and fast filling operations.
  • Table 1 filling stations A-P filling line Line 1 Line16 bottling plant 1 Dosier horrungsaku 10 control 20 bus line 22 display unit 30 storage container 40 Compressed air supply 42 Valve 44 pressure gauge 46 Compressed air supply 50 Flowmeter 52a - 52p filling valve 54a - 54p filling tips 56a - 56p Filling container (shampoo bottle) 60a - 60p conveyor belt 70
