ABSTRACT:
An apparatus for milking animals which includes one or more milking compartments where the animal is milked, and a milking robot for automatically connecting and disconnecting teat cups to animals being milked in said milking compartments. The milking robot includes a carrier for each teat cup and has a piston and cylinder member that is interconnected to the teat cup by a cord, the cord being played out from the carrier when a teat cup to which it is connected is connected to the animal's teat. The teat cup is pulled back onto a site therefor on the carrier by the piston and cylinder member when the teat cup is disconnected from the animal's teat. A sensor is provided for sensing when a teat cup is not properly pulled back and properly seated at its site therefor. The sensor can be a micro-switch at the site or a micro-switch which is actuated by the piston of the piston and cylinder member when it is fully extended, or it can be mounted on the teat cup and actuated when the teat cup is not at the proper angular disposition which it would have if properly received at its site on the carrier. When a teat cup is not so properly sited after being disconnected or dislodged from an animal's teat, this circumstance indicates a malfunction of which the sensor, via a computer, causes an operator to be notified.
