  • Device for automatic removal of milking apparatus from an animal's teats
    Patent number: 5431128
    Abstract: A device for automatic removal of a milking apparatus (6) comprises an operating unit (2) having a cord drum with a cord (13), and a driving motor for turning the cord drum for winding the cord on the latter. The free end of the cord is connected to the milking apparatus, whereby the cord pulls the milking apparatus off the teats of the animal as the cord drum is turned by the driving motor. According to the invention, the driving motor comprises a pneumatically operated motor. The advantage is that the operating unit can be made compact and with a low weight, and that the milker can unwind the cord without any substantial resistance from the motor when the motor is inactivated.
