  • Publication number: 20100148402
    Abstract: During the production of teat rubbers, in particular of teat rubbers containing a high percentage of silicone, pressure is applied when the teat rubber preforms are removed, the radial expansion of teat rubber areas being appropriately limited to a maximum value. Hence, the removal can be executed automatically and at a comparatively high temperature without irreversible damage being caused to the material. The removal process can be supported by an appropriate contact surface whose contour corresponds, at least partially, to the outer contour of the preform. Furthermore, an appropriate removal device is provided.

  • Patent number: 7637228
    Abstract: A milk hose for connecting a milk collecting piece to a teat cup in an automatic milking plant comprises a first end area which is adapted to be fixed to the connection element of the teat cup and a second end area which is adapted to be fixed to the connection element of the milk collecting piece. Furthermore, said second end area has provided thereon an impact-absorbing area comprising elongate impact-absorbing elements, which, when subjected to a radial impact load, are deformed and/or bent at least sectionwise in a predefined preferred direction, and/or nipple-shaped impact-absorbing elements which are deformed and/or bent when subjected to said radial impact load. In addition, an impact-absorbing device for mounting on a milk hose is described.

  • Patent number: 7395780
    Abstract: A milk collecting piece comprises a kink element having a bending edge which ensures reliable kinking and thus maintenance of the operating vacuum in milk tubes which are guided outwards in a direction oblique to the longitudinal axis. In one embodiment, the milk collecting piece comprises a connection surface provided with an opening into which an end portion of the milk tube is introduced, so that a reliable function is obtained due to the provision of the kink element, whereby due to the manner in which the milk tube is mounted on the collecting piece, a smaller amount of milk coating collects and deposits on transition areas. In a further embodiment, the bending edge of the kink element is positioned in such a manner that said edge efficiently prevents the milk tube from getting detached from connection elements which are guided outwards in an oblique manner, and ensures vacuum-tight kinking of the milk tube at the same time.

  • Publication number: 20070277737
    Abstract: According to the invention, an actuator is provided for a milking installation, wherein the actuator is fixed at a distance to a teat cup cluster and is mechanically coupled to the teat cup cluster via a flexible component so as to incite a stimulating movement of the teat cup cluster on the udder by means of an actuator element. The inventive actuator can also be used to adjust the angle of tilt of the teat cup cluster during milking. The invention also provides a retaining device for teat cups, comprising a fastening device for fixing the retaining device on a predetermined milking position, wherein the retaining device is furthermore formed to maintain, during a first operational phase, every teat cup of a plurality of teat cups in a fixed position relative to each other and to allow manual access to every retained teat cup in such a manner that during a second operational phase every teat cup can be manually moved in several directions relative to the retaining device and at least one additional teat cup.

  • Publication number: 20070245967
    Abstract: A teat rubber for use on a milking cup of a milking apparatus, comprising a head part having provided thereon a sealing lip that forms an insertion opening for a teat, a holding edge for grasping a milking cup sleeve, a suction connecting piece connected to the head part as well as a planar teat bearing section which is formed on the sealing lip provided on the head part and which defines the insertion opening, characterized in that the teat rubber comprises an adhesion element that improves the adhesion between the teat and the teat rubber without affecting the milking process.

  • Patent number: 6895891
    Abstract: An automatic milking plant includes a teat cup connected via a flexible connection hose to a collecting piece for collecting extracted milk and for transmitting a vacuum required for milking. The collecting piece is provided with a connecting piece for the flexible connection hose. The connecting piece and/or the flexible connection hose are implemented such that the flexible connection hose is stiffened in the connection zone of the connecting piece and that the stiffened region of the flexible connection hose extends beyond a milk-carrying area of the connecting piece in the axial direction. An end of a hose sleeve which faces away from the connecting piece is designed asymmetrically in the longitudinal direction, and the hose sleeve encloses the flexible connection hose at least partially in the area of the connecting piece.

  • Patent number: 6860228
    Abstract: The present invention relates to a milking cup comprising a cup sleeve, a teat rubber inserted in the cup sleeve with a head piece and an intake socket connectable with a milk discharge conduit, and comprising an air inlet valve provided on the milking cup and connected with the interior space of the intake socket via a first conduit, which lets atmospheric air penetrate into the intake socket in response to a relief phase, during which a higher pressure causing a folding-in of the intake socket relative to the milking vacuum pending in the milk discharge conduit is generated in a clearance between the cup sleeve and the intake socket. The invention is characterized in that an opening toward the interior space of the teat rubber is provided in the head piece of the teat rubber, wherein the opening can controllably be supplied with atmospheric air in response to the relief phase.
