Device for automatically milking an animal

A method of controlling the automatic milking of an animal using an automatic milking device, the method comprising:

• attaching at least two teat cups to at least two teats of the animal using a milking robot, each teat cup being connected via a teat cup line to a common milk line;
• applying a vacuum to the teat cups to cause milk to be withdrawn from the teats and to be supplied to the respective teat cup lines and to the common milk line;
• determining, using a milk-determining element, the teat cup from which milk present in the common milk line has come and emitting a determination signal;
• performing measurements on the milk present in a sensing region of the common milk line and emitting a measurement signal;
• and
• controlling the operation of the device on the basis of the measurement signal and the determination signal;
• wherein a valve is disposed in each teat cup line and is directly controlled by the milk-determining element to selectively supply milk from the individual teat cup lines to the sensing region of the common milk line.

A device for automatically milking an animal, comprising:

• a milking robot;
• at least two teat cups;
• a common milk line for discharging milk coming from the teat cups, each teat cup being connected via a teat cup line to the common milk line;
• a milk-determining element for determining the teat cup from which milk present in the common milk line has come and for emitting a determination signal;
• a measuring device comprising a common sensor for performing measurements on milk obtained from the animal and for emitting a measurement signal, the common sensor being disposed in the common milk line;
• and
• a computer for receiving the measurement signal and the determination signal to determine from which teat cup comes the milk that is measured by the common sensor and controlling the operation of the device,
• wherein a valve controlled by the milk-determining element is disposed in each teat cup line between the milk-determining element and the common milk line and wherein each teat cup line is provided with a bypass line, the bypass line having a first end connected to the teat cup line in a position between the teat cup and the milk-determining element and a second end connected to the common milk line in a position downstream relative to the common sensor.
