  • Patent number: 10798911
    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.

  • Patent number: 9072272
    Abstract: A milking installation includes first and second fluid systems (S1; S2) and a coupling arrangement for connecting and disconnecting the first fluid system (S1) to and from the second fluid system (S2). In a connected state, the first and second fluid systems (S1, S2) are in fluid communication with one another, and in a disconnected state the first and second fluid systems (S1, S2) are not in fluid communication with one another. The coupling arrangement includes a common cavity (CC) configured to be alternately included in the first fluid system (S1) or in the second fluid system (S2) for through passage of fluid while the first and second fluid systems (S1, S2) are disconnected from one another. The first fluid system (S1) also has a by-pass arrangement configured to allow fluid in the first fluid system (S1) to circulate independently from the passage of fluid through the common cavity (CC) when the common cavity (CC) is included in the second fluid system (S2).

  • Patent number: 8127714
    Abstract: A method for animal management is provided in a milking system including a a milking box, a milking apparatus for milking animals, an enclosed waiting area from which the animals are capable of entering the milking box, and a gate arrangement, in which each of the animals is allowed to enter and pass the waiting area if the animal, after having been identified, fulfills a criterion. The method includes measuring a time an animal waits in the waiting area before being milked; determining a ranking for the animal based on the time, the ranking being a measure of a hierarchic order of the animal among the animals milked in the milking system; and performing an action with regard to the milking system depending on the determined ranking.

  • Patent number: 6830008
    Abstract: A more effective method of automatically milking animals in an automatic milking facility is disclosed. The method includes (i) assigning a respective threshold value (t.v.) to each of the udder quarters (1st u.q.; 2nd u.q.; 3rd u.q.; 4th u.q.) of an animal to be milked indicating when the milking of the corresponding udder quarter is to be ended; (ii) measuring the milk flow from each udder quarter of animal during milking; and (iv) ending the milking of an udder quarter of the animal (end1; end2; end3; end4) in dependence on the measured milk flow from that udder quarter reaches the corresponding threshold value. The threshold value of the udder quarter (4th u.q.) of the animal, for which the ending of milking very last remains is raised (t.v.115%; t..V.inf; t.v.(t); t.v.

  • Patent number: 6684809
    Abstract: The invention regards an apparatus for performing an animal related operation like milking or grooming, where the animal (9) is confined in a stall (8). In order to protect animals and equipment, it is so arranged that any breaking of the functions activates an activable state, which retracts devices (21; 10) from the region of confinement before the apparatus is allowed to finally stop.

  • Publication number: 20030154924
    Abstract: For sensing presence of foremilk, in the separation of foremilk or for detecting incorrect premilking, the transparency of the milk to transmission of light therethrough is sensed by a sensor (4), and a control unit (12) which receives signals from the sensor operates a valve (7) so that foremilk is diverted to a waste container (10) whereas good quality milk passes to a storage container (3). The inverted peak in the transparency curve which is indicative of foremilk is detected and the control unit actuates the valve (7) to minimise loss of good quality milk with the foremilk.

  • Patent number: 6550425
    Abstract: A gate for use in cattle handling systems, where animals pass between different areas separated by fences and passage from one area to another takes place through the gate. The gate is spring biased to occupy a closed position, in which it is lockable by at least one catch member being releasable in response to the approach of an animal identified as allowable for passage. The catch member is arranged to provide free passage at all times through the gate in one opening direction and to be actuatable for releasing the gate for opening in the opposite opening direction.
