Abstract

A milking arrangement includes robot milking stations connected to a milk conduit with an outlet end. A connection conduit connected to the outlet end includes an outlet member. A cleaning device for cleaning the milk conduit includes a cleaning conduit having a first connection member. A milk tank includes a second connection member. The outlet member is movable between and connectable to the first connection member in a primary state, and to the second connection member in a secondary state. A controller communicates with the milking stations, the cleaning device and a user interface. When determined to change the state, measures for preparing the arrangement for the change are automatically performed. Thereafter, the user interface indicates to an operator that the arrangement is ready for the change.

wherein the outlet member ( 9 ) of the connection conduit ( 8 ) is movable between different states, including a primary state in which the outlet member ( 9 ) is connected to the first connection member ( 12 ), and a secondary state in which the outlet member ( 9 ) is connected to the second connection member ( 22 );
a sensor arrangement ( 30 - 32 ) configured to sense when the outlet member ( 9 ) is in the primary state or to sense when the outlet member ( 9 ) is in the secondary state;
a user interface ( 41 ); and
a controller ( 40 ) communicating with the at least one robot milking station ( 1 ), the cleaning device ( 10 ), the sensor arrangement ( 30 - 32 ) and the user interface ( 41 ), wherein,
the controller ( 40 ) is configured to receive an order determining that a state of the milking arrangement is to be changed, the change of the state of the milking arrangement including a change of state of the outlet member ( 9 ) of the connection conduit ( 8 ),
the controller ( 40 ) is configured, upon the controller ( 40 ) receiving the order, to perform automatically measures for preparing the milking arrangement for the change of the state of the outlet member ( 9 ) of the connection conduit ( 8 ), and
the controller ( 40 ) is configured to indicate via the user interface ( 41 ) to an operator that the measures have been performed and that milking arrangement is ready for the change of the state of the outlet member ( 9 ) of the connection conduit ( 8 ).

2. The milking arrangement according to claim 1 , wherein the sensor arrangement ( 30 - 32 ) is configured to sense the state of the outlet member ( 9 ) of the connection conduit ( 8 ) and to communicate sensing of one of said primary state and said secondary state to the controller ( 40 ).

3. The milking arrangement according to claim 2 , wherein the controller ( 40 ) is configured to activate the cleaning device ( 10 ) when the primary state is sensed by the sensor arrangement ( 30 - 32 ) and communicated to the controller ( 40 ) and wherein the controller ( 40 ) is configured to activate the at least one robot milking station ( 1 ) when the secondary state is sensed by the sensor arrangement ( 30 - 32 ) and communicated to the controller ( 40 ).

4. The milking arrangement according to claim 1 , wherein the controller ( 40 ) communicates with the milk pump ( 4 ) of the at least one robot milking station ( 1 ) and is configured to stop the milk pump ( 4 ) as a first measure of said measures when preparing the milking arrangement for the change of the state to a cleaning operation.

5. The milking arrangement according to claim 1 , wherein the milking arrangement comprises a closing valve ( 42 ), communicating with the controller ( 40 ) and provided on the milk conduit ( 6 ) downstream the at least one robot milking station ( 1 ) and upstream the outlet end ( 7 ), and wherein the controller ( 40 ) is configured to close the closing valve ( 42 ) as a second measure of said measures when preparing the milking arrangement for the change of the state to a milking operation.

6. The milking arrangement according to claim 1 , wherein the milking arrangement comprises an evacuating device ( 43 ), communicating with the controller ( 40 ) and provided on the milk conduit ( 6 ) downstream the closing valve ( 42 ) to evacuate the milk conduit ( 6 ), and wherein the controller ( 40 ) is configured to activate the evacuating device as a third measure of said measures when preparing the milking arrangement for the change of the state to a milking operation.

7. The milking arrangement according to claim 1 , wherein the milking arrangement comprises a blocking valve ( 45 ) provided on the milk conduit ( 6 ) downstream the robot milking stations ( 1 ) immediately upstream the outlet end ( 7 ), and wherein the controller ( 40 ) is configured to close the blocking valve ( 45 ) as a fourth measure of said measures during moving the outlet member ( 9 ) of the connection conduit ( 8 ) from one of the first connection member ( 12 ) and second the connection member ( 22 ) to the other of the first connection member ( 12 ) and second the connection member ( 22 ).

8. The milking arrangement according to claim 1 , wherein the outlet member ( 9 ) of the connection conduit ( 8 ) is manually movable between and connectable to one of the first connection member ( 12 ) and the second connection member ( 22 ).

9. The milking arrangement according to claim 1 , wherein the sensor arrangement ( 30 - 32 ) comprises an outlet sensor ( 30 ), associated with the outlet member ( 9 ) and configured to sense at least one of said primary state and said secondary state.

10. The milking arrangement according to claim 1 , wherein the sensor arrangement ( 30 - 32 ) comprises a first sensor ( 31 ), associated with the first connection member ( 12 ) and configured to sense said primary state, and at least one second sensor ( 32 ), associated with the second connection member ( 32 ) and configured to sense said secondary state.

11. A method of operating milking arrangement comprising at least one robot milking station ( 1 ) comprising a set of teatcups ( 2 ), a milk receiving unit ( 3 ), and a milk pump ( 4 ),
a milk conduit ( 6 ) to which the at least one robot milking station ( 1 ) is connected and which comprises an outlet end ( 7 ),
