Abstract

In a drink-dispensing installation, an authorized individual is required to identify himself by entering a code into a code-registering station. The drinks-dispensing installation includes an automatic valve and a manually-actuable hand-dispensing valve connected in series with the automatic valve. The automatic valve is maintained in an open position and is closed at a time subsequent to the start of opening the hand valve when a drink is first drawn off from the dispensing installation without first entering the code.

Claims

1. A method of monitoring a drinks dispenser in a drink-dispensing installation having an automatic valve and a manually actuable hand-dispensing valve connected in series with the automatic valve and requiring an authorized individual to identify himself by entering a code to dispense the drinks, comprising the steps of:

maintaining the automatic valve open, opening the hand valve and closing the automatic valve at a time subsequent to a start of the opening of the hand valve when a drink is drawn from the dispenser without first entering the code.

2. A method according to claim 1, including the step of commencing the closing of the automatic valve in response to opening the hand valve without a code having been entered and thereafter slowly closing the automatic valve.

3. A method according to claim 2, including continuously closing the automatic valve after its closure has been commenced.

4. A method according to claim 1, including closing the automatic valve in a stepped manner in response to opening the hand valve without a code having been entered.

5. A method according to claim 1, including maintaining the automatic valve completely or partially open for a bridging time and closing the automatic valve within a subsequent brief closure time of approximately 0.1 second to approximately 1 second.

6. A method according to claim 1, including emitting an acoustical or visual signal in response to opening the hand valve without a code being entered beforehand, and beginning closing the automatic valve once the visual signal has appeared or the acoustic signal has been sounded.

7. A method according to claim 1, including stopping the closing of the automatic valve and returning the automatic valve to its completely open position in response to closing the hand valve after the start of drawing off a drink without a code entry and before the final closed position of the automatic valve has been reached.

8. A method according to claim 1, including terminating the closure of the automatic valve after the hand valve has been opened without a code entry in a period of preferably 0.3 second to 3 seconds.

9. A method according to claim 1, including, in the event of an incorrect operation when the automatic valve has been finally closed and a code is subsequently entered, interrogating whether a prior removal attempt has been conducted without an entered code before the automatic valve is closed, and opening the automatic valve in response to the interrogation.

10. A method according to claim 1, including, subsequent to an attempt at drinks removal without a code being entered and closure of the hand valve within a pre-settable time, closing the automatic valve irrespective of the position of the hand valve in response to a subsequent second attempt at drinks dispensing without a code being entered.

11. A method according to claim 1, including closing said automatic valve in response to (a) exceeding a pre-settable number of incorrect operations within a unit of time, (b) exceeding a pre-settable limit value for a permissible number of incorrect operations during a billing period, or (c) upon exceeding a quantity limit value for a non-accountable quantity of drinks.

12. Apparatus for monitoring a drinks dispenser in a drink-dispensing installation, comprising:

a drinks-dispensing station;

a code-entering and registering station;

a drinks supply line having a normally open automatic valve, a throughflow sensor connected in series with said automatic valve and a hand-operated valve assigned to said drinks-dispensing station;

an electronic control unit;

said automatic valve and said throughflow sensor being connected to said control unit for closing said automatic valve in response to dispensing a drink at said dispensing station without a code being entered at said code-entering and registering station and at a time subsequent to opening the hand valve.

13. Apparatus according to claim 12, including means for closing the automatic valve over a period of time.

14. Apparatus according to claim 12, including means for continuously closing the automatic valve for a period of time.

15. Apparatus according to claim 12, including means for closing the automatic valve in a stepped manner.
