  • Patent number: 8944004
    Abstract: A detecting arrangement is provided for a teat cleaning device including a teat cleaning cup in which teats of milking animals are contained during cleaning thereof. The detecting arrangement comprises a measuring device provided for automatically measuring a teat related parameter in or adjacent to the teat cleaning cup at completion of a teat cleaning process, and a processing device operatively connected to the measuring device and provided for automatically comparing the measured teat related parameter with a reference value and for automatically determining whether the teat of the milking animal has been contained in the teat cleaning cup unfolded during the teat cleaning process based on the comparison.

  • Patent number: 8624744
    Abstract: An arrangement is provided for attaching teat cups to teats of a milking animal in a rotary milking system having a milking stall for housing the milking animal during milking. The arrangement comprises a three-dimensional camera configured to be directed towards the udder of the milking animal in the milking stall and to repeatedly record three-dimensional images of the udder of the milking animal in real time. The three-dimensional camera is further configured to be directed towards the teat cups located in a magazine and to repeatedly record three-dimensional images of the teat cups in real time. The arrangement also includes an image processing device configured to repeatedly detect the teats of the milking animal and determine the positions of the teats in three spatial dimensions based on said repeatedly recorded three-dimensional images of the teats.

  • Publication number: 20120132142
    Abstract: Methods and systems are disclosed for controlling a milking installation having a movable element that performs a procedure related to extracting milk from milking animals. An exemplary method includes capturing a three-dimensional image of a detected entity present in an operating zone of the movable element, and comparing the captured three-dimensional image to stored image reference data. Based on the comparison, the detected entity is categorized entity as one of a first predefined entity and a second predefined entity. The first predefined entity corresponds to a milking animal and the second predefined entity corresponds to an entity other than a milking animal. Based on the categorization, a control determination is made of whether to allow the movable element to continue the procedure related to milk extraction or to initiate a safety measure. Then, the control determination is implemented.

  • Patent number: 7377232
    Abstract: In an automatic milking installation including a robot arm (2) with a gripper (3) for attaching teat cups (4) to the teats of an animal, e.g. a cow, to be milked, for applying a teat dip to the teats after milking different members, such as spray nozzles (5a, 5b), dipping cups (5c, 5d) and sponge or cloth rollers (5e), are provided for applying different teat dip compositions. Under the control of a computer, the robot arm collects the member (5) appropriate for supplying the selected composition and takes it to a position appropriate for application of that composition. The selection can e effected in dependence upon the teat skin condition, e.g. detected by a camera (15) and/or environmental conditions.
