Device and method for controlling the filling of a cup by a vending machine
First Claim
1. A device for controlling filling of a receptacle with liquid in a drink vending machine comprising:
- means for filling the receptacle with liquid;
means for visually marking a desired liquid fill level for the receptacle;
means for emitting a signal towards the receptacle to generate an incident signal;
means for receiving the incident signal coming from the receptacle, wherein the receiving means is a series of photoelectric receivers; and
means for controlling the filling means to cease filling, the controlling means configured for processing of the incident signal by measuring at least one variable which is representative of the desired fill level and is a displacement of a light incident signal measured by the receivers; and
then stopping the filling means from further delivery of liquid when the measured variable reaches or exceeds a certain predefined threshold.

Abstract
A device for controlling the filling of a receptacle with liquid by a drink vending machine. The device includes visual marking device for marking the liquid fill level in the receptacle, a device for emitting a signal towards the receptacle, a device for receiving an incident signal and which receives the incident signal returning from the receptacle and a controlling device configured for commanding the stoppage of filling on the basis of a variation of the incident signal. The receiving device includes a series of photoelectric receivers and at least one variable which is a displacement of a light incident signal measured by the receivers.

21. A device for controlling filling of a receptacle with liquid in a drink vending machine comprising:
-
means for filling the receptacle with liquid; means for visually marking a desired liquid fill level for the receptacle; means for emitting a signal towards the receptacle to generate an incident signal; and means for receiving the incident signal coming from the receptacle;
wherein the visual marking, signal emitting and signal receiving means are displaceable together through an angular arc in order to modify the marking of the desired fill level of the receptacle. - View Dependent Claims (22)

23. A method for controlling filling of a receptacle with liquid from a drink vending machine which comprises:
-
visually marking a desired liquid fill level a desired liquid fill level for the receptacle; emitting a light signal towards the receptacle to generate a light incident signal; receiving the incident signal coming from the receptacle by a series of photoelectric receivers with at least one variable measured by the receivers is a displacement of the light incident signal; monitoring of a variable relating to the light incident signal and representative of an actual liquid level in the receptacle; and stopping the filling of the receptacle when the variable reaches or exceeds a predetermined threshold. - View Dependent Claims (24)
