  • Patent number: 11832583
    Abstract: The milking apparatus includes a cluster (4) connected to a retraction line (10), and a cylinder (11) having a piston (13) being movable between first and second end positions. The piston acts on the retraction line to move the cluster to a retracted rest position when moved to the second end position, and to permit the cluster to be moved to an active milking position when the piston is in the first end position. A switch device (30) may alternate between a first state and a second state. The retraction line permits the switch device to change from the first state to the second state when a movement of the cluster from the retracted rest position is initiated. The switch device initiates in the second state supply of a pressurized medium to the cylinder to force the piston to the first end position.

  • Patent number: 8662012
    Abstract: A positioning system for at least one flexible tubular element (5, 6, 9) connected to a cup-shaped member (4, 8) includes a control unit (14) which is arranged to estimate an individually adapted release length of the tubular element (5, 6, 9) in response to information from a sensing unit (12, 13a, 13b) arranged to sense a parameter allowing estimation of the position of a teat of an animal. The control unit (14) is also arranged to control the positioning mechanism to adjust the release length of the tubular element (5, 6, 9) to the estimated individually adapted release length.

  • Patent number: 7891316
    Abstract: A rear milking cluster hose support arm for supporting a milking cluster hose in an existing milking system where milking is done from a rear of a cow includes a rubber bumper for supporting an existing cluster hose and a rectilinear rod. The apparatus further includes a rod holder and a selectively adjusting mechanism with a coupling nut, an air hose, a tee union adapter, and a flattened lever. A predetermined oscillating air pressure level is introduced into the cylinder from the existing air supply source to thereby raise and lower the coupling nut and articulate the lever about the rod to thereby adjust the position of the rod and the rubber bumper respectively during non-operating conditions.

  • Patent number: 7066108
    Abstract: The invention refers to a device and a method for carrying a milking member (1), which includes at least one teacup (3) and which is connected to a milking machine (5) via a flexible conduit member (6). A support element (10) is fixedly mounted in or at a milking box (13) arranged to receive an animal to be milked. An arm arrangement (9) is pivotably connected to the support element and arranged to support the milking member at least in connection with the application of the teacup to a teat of the animal. The arm arrangement is movable from a first position, in which the milking member is located beside the animal, to a second position, in which the milking member is located below the animal. The device includes a first part arranged to lock the milking member in relation to the arm arrangement in order to facilitate the application of the teacup to the teat.

  • Patent number: 6684809
    Abstract: The invention regards an apparatus for performing an animal related operation like milking or grooming, where the animal (9) is confined in a stall (8). In order to protect animals and equipment, it is so arranged that any breaking of the functions activates an activable state, which retracts devices (21; 10) from the region of confinement before the apparatus is allowed to finally stop.

  • Patent number: 6289845
    Abstract: A milking equipment comprises a milking member (1) having teatcups (3) and a milk hose (4) connected to the milking member. A balancing device (6, 10, 11), which carries the milking member and at least a portion of the milk hose, is adjustable to an application position (FIG. 1), at which the balancing device is arranged to balance essentially the weight of the milking member and the weight of said portion of the milk hose in order to permit a milker to apply the teatcups to the teats of an animal without the need for the milker to carry the whole weight of the milking member. Furthermore, the balancing device is adjustable to a milking position, at which essentially the whole weight of the milking member acts on the teats of an animal when the teatcups are attached to the teats.
