Rotary parlour for automatic milking of animals

A rotary parlor for automatic milking of animals, comprising:

• an annular rotary platform (2) forming a support surface for the animals (1);
• driving means (9) arranged to supply a rotary motion to the platform (2);
• positioning parts (4, 6) defining predetermined animal milking positions (3) on the platform (2), said positioning means comprising a feeding trough (6) located at an inner periphery (2a) of the annular platform (2) for each milking position (3);
• a radially displaceable robot arm (13) adapted to attach teat cups (7a) to the teats of an animal (1) which has entered a milking position (3) on the platform (2) wherein the robot arm (13) has an extension from an inner end portion (13′) to an outer end portion (13″);
• and
• a transport device (14) comprising a rail member (14a) arranged at a higher level than the robot arm (13), the rail member (14a) positioned extending in a substantially radial direction in relation to the annular platform (2) with a first distal end located inside the outer periphery (2b) of the platform (2) and a second distal end located outside the outer periphery (2b) of the platform (2), the robot arm (13) arranged in a hanging position on the rail member (14a), wherein,
• the transport device (14) is adapted for radially displacing the robot arm (13) between a working position (13a) where the robot arm (13) attaches the teat cups (7a) to the teats of the animals (1) and a resting position (13b),
• wherein in the working position, the entire robot arm (13) is located at a first radial position entirely inside the outer periphery (2b) of the platform, and
• in the resting position (13b) the robot arm (13) is located in a second radial position outside the outer periphery (2b) of the platform (2).

A rotary parlor for automatic milking of animals, comprising:

• an annular rotary platform (2) adapted to form a support surface for the animals (1), the annular rotary platform (2) having an inner periphery (2a) and an outside periphery (2b);
• driving means (9) for supplying a rotary motion to the platform (2);
• positioning means (4, 6) for arranging the animals (1) in predetermined milking positions (3) on the platform (2),
• a radially-displaceable robot arm (13) adapted to attach teat cups (7a) to the teats of an animal (1) which has entered a milking position (3) on the platform (2), wherein the robot arm (13) is located in a working position (13a) vertically above or on the platform (2) when the robot arm (13) attaches the teat cups (7a) to the teats of the animals (1);
• and
• a transport device (14) positioned outside the outer periphery (2b) of the platform (2) and comprising a rail member (14a) extending radially over the rotary platform (2), the robot arm (13) hanging from the rail member via a rail engaging element (13d) radially movably connected to the rail member in a hanging position for radially displacing the robot arm (13) between i) a radially outer position of the platform corresponding to a resting position of the robot arm (13) and ii) a radially inner position of the platform corresponding to the working position,
• wherein, by radial movement of the rail engaging element (13d) along the rail member, the robot arm (13) is radially displaced between i) the working position (13a) at the radially inner position, and ii) the resting position (13b) at the radially outer position, and
• wherein, in the working position (13a), the entire robot arm is located entirely inside the outer periphery of the platform (2).
