  • Publication number: 20120210939
    Abstract: A method for controlling the milking by a milking machine includes, during an initial phase of the milking, increasing a milking vacuum and/or a maximum pulsation vacuum for the milking gradually from a first selected vacuum level (1L) towards a second selected vacuum level (2L) to thereby improve teat stimulation and decreasing the risk of a second milk letdown. When a second milk letdown (2ML) is detected, the maximum pulsation vacuum is preferably immediately lowered to a third selected vacuum level (3L), and is kept at that third selected vacuum level until a certain milk flow has been established, whereupon the pulsation vacuum level is then again increased gradually until the second selected vacuum level is reached.

  • Publication number: 20100282173
    Abstract: A method for controlling the milking by a milking machine, which milking machine includes a plurality of teat cups (19), each teat cup having a flexible teat receiving liner (33) arranged inside a rigid teat cup shell (35), wherein, during milking, a working vacuum is applied to the interior of the teat receiving liner of each teat cup to draw milk from a respective teat (37) of a milking animal while the teat receiving liner of the respective teat cup is periodically opened and collapsed by application of a pulsating vacuum between the teat receiving liner and the teat cup shell, and according to the method, a flow level of milk drawn from the milking animal is measured and, if the measured flow level is above a threshold, the pulsation ratio of the periodic opening and collapsing of the teat receiving liner of one or more of the teat cups is decreased for a following part of the milking or for a following milking of the milking animal.

  • Publication number: 20100236484
    Abstract: A milking system includes a vacuum pump (11); milking equipment (15); a conduit (14) connecting the milking equipment to the vacuum pump; and a first vacuum regulator (25) provided to maintain a preset vacuum level in the milking equipment. A second vacuum regulator (27, 29, 30a) is arranged between the first vacuum regulator and the vacuum pump and is provided for regulating the preset vacuum to a desired level. Preferably, the second vacuum regulator includes a pressure sensor (30a) provided for measuring a pressure level in the milking system; adjustable air admitting elements (31), e.g. a solenoid valve, provided for admitting air to enter the conduit; and a control device (29) provided for controlling the second vacuum regulator depending on the measured pressure level.

  • Patent number: 7690328
    Abstract: The invention relates to a milk conveyer device (100) for an animal. The milk conveyer device is to be implemented in a milking arrangement which comprises a milk storage reservoir (101) coupled to a milking attachment for attaching to an animal to be milked through a main milk conduit (103, 105). A sample element (109, 111) extracts milk, which is collected in a sample reservoir (115, 117). The sample reservoir (115,117) is connected to an analysis element (129) through an analysis conduit (123, 125). During the flow of the milk from the sample reservoir to the analysis element (129), the milk itself provides a cleaning effect. The flow is initially at a high flow rate and later at a reduced flow rate. A plurality of analysis conduits (123, 125) are connected to the analysis element (129), which comprises a selector unit (127), which couples milk from one of the analysis conduits (123, 125) to the analysis element (129).

  • Patent number: 6150986
    Abstract: A transponder for, for example, domestic animals can receive high frequency energy and transmit information of an antenna (L.sub.x, L.sub.y, L.sub.z) and has a storage capacitor (C.sub.5) for storing received energy, which is used for transmitting on the antenna. In order to make the antenna less sensitive to the geometric direction of the received high frequency energy, it has a plurality of antenna coils (L.sub.x, L.sub.y, L.sub.z), that are arranged in an angle to each other, e.g. perpendicularly to each other. Monitoring circuits (LD.sub.x, LD.sub.y, LD.sub.z, 1) can detect the energy received on each coil and compare the detected values to each other and can, for issuing information, use that coil on which the largest energy has been received. Thereby, the transmission can be made in a direction which is considerably more optimal than a direction which otherwise would be obtained in a more random fashion.
