A rotary parlour for milking of animals includes a rotary platform unit and storing devices connected to the platform unit and adapted to hold a number of teat cups in predetermined parking positions. The storing devices are supported by a supporting mechanism comprising an elevating part adapted to move the storing device between an operating position in which the storing device holds at least a part of the parked teat cups at a higher level than the lowest level of the upper surface of the platform unit and a non-operative position in which both the storing device and the parked teat cups are located at a lower level than the lowest level of the upper surface of the platform unit.

Rotary parlour for milking of animals

A milking system includes a milking robot with a robot arm for applying teat cups to the teats of an animal, an optical detector () for detecting radiation emitted and/or reflected from the animal and a controller. The detector has a housing () with a window () and a detecting element () enclosed in the housing that is sensitive to the emitted or reflected radiation passing through the window. In order to prevent contamination from impacting on the detector window, an airflow arrangement is provided that can be connected to a source of pressurized air and has at least one aperture () disposed adjacent the detector window () for generating a curtain of air that flows parallel with the surface of the window. The controller controls the generation of the air curtain to coincide with the start of at least one further operation controlled by the controller.

Method and apparatus for protecting an optical detection device from contamination

A milking arrangement includes a milking robot () having a first link (L), a second link (L), a third link (L), an end effector (E), sensor () and a control unit (). The first link is rotatable to a first angle within a first angle range (&#x3b1;) via a first joint (). The second link is rotatable to a second angle within a second angle range (&#x3b1;) via a second joint (). The third link (L) is rotatable to a third angle within a third angle range (&#x3b1;) via third joint (). The links (L, L, L) are rotatable so that the end effector is movable within a three-dimensional workspace (W). Each position of the end effector within the workspace corresponds to a single combination of the first, second and third angles.

Milking robot, and a milking arrangement

A griper device mountable on a robot arm of a milking robot provided for automatically attach teat cups to the teats of a milking animal, the gripper device comprises an electromagnet from gripping teat cups made of a magnetic material, the electromagnet including a coil feedable with a current a core of a magnetic material arranged at least partly within the coil; and a support structure for holding the electromagnet. The core comprises two end and portions in a single face of the electromagnet wherein the two end portions constitute different poles of the electromagnet and are shaped to be engagable with each of the teat cups in a close fit.
