DE19847912A1 - Cup for milking machine has thin wall sections of elastic inner section to improve grip onto teat, held concentrically inside outer housing - Google Patents

Abstract

A cup for a milking machine has an elastic tube (6) fitted inside the rigid cup (1) and with an upper collar (3) to fit over the teat (14). The upper part of the elastic tube has one or two thin wall sections (5) to assist with the fitting of the cup and for improving the grip onto the teat. When the cup is fitted to the teat a suction pressure between the tube and the cup causes the thin wall section to extend and ease the fitting. While fitted the cup is held in place by suction in the milking line. The thin sections ensure a good grip during the milking cycles.

Description

In a further form of training, the thin wall area of a teat rubber or Milk cup used to close the teat receiving space from the vacuum. In the mo Their milking technology has milking processes that switch on the vacuum during the massage cycle lifting the teat or at least reducing it significantly, great advantages with regard to udder Proven health and milk yield.

Constructions are known which are by means of a clamping piece or with an set in the hose part of the teat rubber a closure of the teat receiving space from Apply vacuum. However, these known measures have the disadvantage that they with regard to the passage of milk or with regard to the closure of the Vacuum have an unsafe function. Furthermore, they are disadvantageous in cleaning.

The object of the invention is to eliminate these disadvantages.

The vacuum closure of the teat receiving space from the permanent vacuum in the massage cycle can be particularly through the termination according to the invention with thin wall area effective and simple in the teat cup or milking cup, preferably directly below realize the teat, with free flow in milk removal and in Cleaning is guaranteed. Another advantage is that the conclusion is integrated in the teat hose and no further parts are required. Especially The termination according to the invention can advantageously be designed such that part of the Thin-wall area, which is needed at the end, at the same time for massage of the teat serves. This thin wall area can also be taken from the end towards the teat have wall thickness. There is also the possibility of the teat receiving space to ventilate with atmosphere by means of a duct that leads past the end.

Another object of the invention is to relieve the stress during the massage cycle To provide teat by closing the vacuum and on the other hand a trouble-free To ensure milk drainage in the relief phase of the teat from the vacuum. this will guaranteed by the conclusion according to the invention that a total Conclusion takes place when there is no milk flowing, but the closure organ when milk flows initially only closes the liquid-free cross section of the passage and the milk can drain from the vacuum even when the teat is relieved.

It is particularly advantageous to have such a conclusion with those in the main register combination 198 40 732.7 described thin wall areas.  

Fig. 1 shows an embodiment of the closure according to the invention within a teat rubber in the suction cycle. The teat rubber has a smaller inner diameter below the teat receiving space, through the difference in diameter, a closing opening is formed, on the bearing surface 24 of which the end of the permanent vacuum is carried out. The smaller inner diameter can be arranged asymmetrically to the larger diameter of the hose part. The angle 36 of the support surface 24 is preferably less than 90 ° to the longitudinal axis. The support surface 24 is particularly advantageously designed as a bead-shaped elevation.

The wall thickness of this exemplary embodiment is so thick-walled below the contact surface end 30 that it does not react or only insignificantly to the pressure differences occurring during milking. The tube part 26 above the end is flexible and has a thin-wall region 55 on the opposite side, which runs as indicated in the dashed line 37 and ends at the end 33 of the contact surface. In the suction cycle, vacuum prevails in the interior 4 on the teat 14 as well as in the exterior 2 .

With the support surface 24 , which is formed by a preferably integrally formed ring, the tube part can also be flexible below the closure, a closure of the interior 4 from the permanent vacuum is also possible in a conventional teat rubber of a two-room cup when the teat rubber collapses in the massage cycle, as in Fig. 3 shown.

In the massage cycle, FIG. 2, the outer space 2 is supplied with atmosphere or excess pressure via the spout 13 , which causes the thin-wall region 55 to be pressed inwards in the direction of the support surface 24 and the tube part 26 , and preferably largely over the edge of the boundary line 37 trough-like collapse.

The support of the thin-wall area 55 on the support surface 24 brings about the completion of the interior 4 from the permanent vacuum of connection 11 , the teat 14 preferably being massaged at the same time. The hose part merges into a thin-wall region 55 along the boundary line 37 of the flexible remaining hose part. This preferably mul-shaped design of the flexible remaining hose part 26 along the boundary line 37 preferably causes the thin-wall region 55 to collapse into this trough shape, which at the same time causes the trough cheeks of the flexible hose part 26 to contract , so that advantageously additionally a massage onto the trough cheeks Teat 14 is exercised. This massage sequence also allows a closely encompassing teat cup sleeve 1 and results in a particularly effective massage and blood return on the teat.

By the angle 36 of the support surface 24 to the longitudinal axis and or also by the height of the support surface at 30 , the time of completion can be determined in connection with the subsequent volume reduction in the interior 4 . This can also serve a thick-walled end body 31 on the thin wall area 55 corresponding to the bearing surface 24 .

The support surface 24 is advantageously produced as a thickened wall part of a teat rubber or milking cup, but the stability of the closure can be achieved by an inflexible insert part.

The closure according to the invention can also be attached separately, without a massage effect, in a tube part below the teat 14 .
