Abstract
The present invention refers to a method and apparatus (1) for detecting liner slips in a milking machine which involves, for each milking unit, a clawpiece and a cluster of teat cups connected to the clawpiece, wherein each teat cup has a rigid shell body and an internal flexible liner, the liner comprising a mouthpiece and a body part, whereby the liner extends through the bottom of the shell body as a short milk tube and is connected to the clawpiece and further, by way of a long milk tube, to a source of steady vacuum, while the annular space, between the teat cup shell body and the teat cup liner, is connected to the clawpiece by a pulse tube and further to a source of pulsating vacuum. Alternatively, each liner in the system is connected to the vacuum source by way of a respective individual long milk tube, wherein the clawpiece is omitted. The invention includes continuously or discontinuously sensing the pressure in the system downstream of said long milk tube(s), and detecting a liner slip in dependence of a predetermined change in said sensed pressure.
