  • Patent number: 10123505
    Abstract: A milk pump device, comprising a passage duct, a first one-way valve, a second one-way valve and a membrane pump. The first and second one-way valves are included in the passage duct and oriented in the same direction relative to each other. The membrane pump is positioned between the first one-way valve and the second one-way valve. The membrane pump forms a first milk meter for generating a first milk measurement with respect to a number of complete pumping strokes of the membrane pump. The milk pump device further comprises a second milk meter for carrying out a second milk measurement with respect to a residual pumping stroke.

  • Patent number: 9422931
    Abstract: A milking installation with a milking robot for automatically connecting teat cups to the teats of a dairy animal has milk lines extending between the teat cups and a milk de-aeration unit or milk glass. A de-aeration port is present at the top of the de-aeration unit and a de-aeration line connects the milk glass to a vacuum system. At the bottom of the milk glass a milk inlet line is provided which connects the milk glass to the milk pump. The milk pump includes a milk inlet, a pump housing, a milk outlet. The milk pump is a membrane pump which type of pump is known to be gentle to the milk and thus reduce occurrence of lypolysis of the milk when pumped through the milking installation.

  • Patent number: 9179639
    Abstract: A milking system for milking a herd of dairy animals includes a first milking device and a second milking device, an identification device for identifying dairy animals to be milked of a herd of dairy animals, and a control device for determining an estimated treatment time of each dairy animal to be milked. The control device also classifies each dairy animal to be milked with the aid of a criterion on the basis of the estimated treatment time in at least a first or second group of dairy animals. The milking system admits the first group of dairy animals to preferably only the first milking device and admits the second group to preferably only the second milking device.

  • Patent number: 8276349
    Abstract: A method of applying stretch film wrapping to an agricultural bale (10) which is of rectangular cross section and using a bale wrapper apparatus which comprises: a table which supports the bale (10) and which operates to rotate the bale generally about its longitudinal axis (11) during a wrapping cycle; a dispenser reel arrangement (12, 13, 16, 17, 20, 21, 24, 25) from which stretch film wrapping is withdrawn so as to form successive overlapping windings of film which cover the bale; and means which applies relative rotation between the table and the dispenser reel arrangement about a second axis (14) which extends substantially perpendicular to said first axis during the wrapping cycle; in which: each winding of film includes a longitudinal edge strip portion and an adjoining longitudinal strip portion; and the longitudinal edge portion has different deformation properties from the deformation properties of said adjoining portion so as to be more readily extensible under a given load than said adjoining port
