Definitions

  • the invention relates to a method for milk withdrawal from a teat of a lactating animal by means of a teat cup connected to a milk-draining system under negative pressure, the interior of which accommodates a teat rubber impacted by pressure changes between a suction phase on the one hand and a relief phase on the other hand, inside the teat a teat tip formed at its end protrudes.
  • the invention relates to a device for removing milk from a teat of a lactating animal by means of a teat cup connected to a milk-draining system which is under vacuum, the interior of which receives a teat rubber applied by pressure changes between a suction phase on the one hand and a relief phase on the other, in the interior thereof the teat protrudes with a teat tip formed at its end.
  • the milking machines common today operate in a periodic change between the suction phase and the relief phase. Milk is withdrawn from the teat during the suction phase.
  • the negative pressure in the teat cup acts on the teat and removes the milk.
  • the teat rubber firmly encloses the teat so that the negative pressure prevailing in the teat cup cannot exert its effect on the teat.
  • preference is given to a mode of operation with a pressure change between atmospheric pressure and negative pressure. This is done in view of the obvious idea of using the negative pressure required for transport at the same time to exert pressure on the teat.
  • the object of the present invention is therefore to improve the method of the type mentioned in the introduction in such a way that the lactating animal is stimulated to improve emptying of the udder.
  • This object is achieved in that in the relief phase is acted on the teat rubber with overpressure, by which a connection existing between the inside of the teat rubber and the milk-draining system is separated immediately below the teat tip.
  • Teat from the milk-draining system is also beyond achieved in the relief phase that the simultaneous suction of air from the interior of the teatcup liner does not occur while the teat is pressurized. In this way it is prevented that air components which move under the influence of the excess pressure in the direction of the teat tip are sucked off there and thus the teat tip also comes under the influence of the negative pressure prevailing in the milk-draining system.
  • Such a negative pressure is harmful in the area of the teat tip during the discharge cycle, since it places a strong mechanical and pneumatic load on the teat tissue. Such a load has a negative effect both on the teat tissue and on the milk flow.
  • the separation of the line from the milk-draining system in the area of the teat tip favors the breakdown of the vacuum.
  • This reduction can be increased until a slight overpressure builds up in the area of the teat tip.
  • the tissue of the teat is relieved both pneumatically and mechanically.
  • the level of the pressure building up on the teat tip depends on the one hand on the external pressure acting on the teat cup liner and the sealing of the interior enclosed by the teat cup liner on the other hand s.
  • a further object of the present invention is therefore to improve the device of the type mentioned in the introduction in such a way that harmful effects of negative pressure in the area of the teat tip are excluded when the surface of the teat is acted on over a large area.
  • This object is achieved in that an annular space provided between the teat rubber on the one hand and the teat cup on the other is acted upon by pressure changes between overpressure on the one hand and underpressure on the other hand and a separation of the underpressure from the teat is provided between the teat tip and the milk-draining system.

  • a further possibility of separating the interior 22 of the teat rubber 18 from the negative pressure of the milk-draining system 1 in the collapsed state of the teat rubber 18 is the teat seal rather to train 9 with walls 37 of different wall thickness. It is thus possible to promote the collapse of the teatcup liner 18 in that the walls 37 have a thin area 38 below the teat tip 34. In addition, it is possible to apply reinforcements 39 to the walls 37. apply each other in the collapsed state of the teat rubber 18. In addition, a large number of further possibilities have become known in the prior art which aim to seal the interior 22 as tightly as possible against the negative pressure of the milk-draining system. For example, it is conceivable to provide the walls 37 with folds 40, which have a specific folding order of the teat rubber 18 as the goal. This fold-in order leads to a safe separation of the interior 22 from the negative pressure of the milk-draining system 1.

In addition, it is also possible to control the excess pressure in the interior 10 in a variable manner. The variability can affect both the level of the overpressure and the duration of its action on the teat rubber 18.

However, it is also possible to carry out the control depending on the time or according to other criteria.
  • the teat tip 34 can be separated from the suppression of the milk-draining system 1 in a similar manner. Complete separation will be carried out regularly. However, it is also possible to maintain a desired suppression at the teat tip 34 with the aid of defined passages.

However, it is also possible to control the intensity of the overpressure in such a way that the teat 17 is acted upon more strongly by the overpressure at individual points and less strongly at other points. In particular, a swelling overpressure in the direction of the teat tip can be acted on in the longitudinal direction of the teat. To prevent blind milking, it is possible to permanently switch off the teat tip from the negative pressure after the milk flow has ended.

Abstract

Dans le procédé pour extraire le lait du trayon d'un animal le lait est aspiré dans un dispositif d'évacuation du lait maintenu sous dépression. Dans ce but, le trayon fait saillie à l'intérieur d'une ventouse qui passe d'une phase d'aspiration d'une part à une phase de détente d'autre part par changements depression. Pour produire ces changements de pression on agit sur la ventouse successivement par surpression d'une part et par dépression d'autre part. En outre, dans la phase de détente, le trayon est séparé de la dépression du dispositif d'évacuation du lait d'une manière déterminée. On soumet la ventouse à une surpression dans la phase de détente, durant toute l'opération de traite ou seulement pendant des intervalles de temps déterminés, et le reste du temps à la pression atmosphérique. Dans le dispositif pour la mise en oeuvre de ce procédé l'espace (10) prévu entre la ventouse (18) d'une part et le gobelet (9) d'autre par est soumis à des changements de pression entre une surpression et une dépression. En outre, entre la pointe du trayon (34) et le dispositif d'évacuation du lait (1) est prévu un organe pour séparer le trayon de la dépression.
