Description

Milchflußübermchung when milking cows

Field of application of the invention

Die.Erfindung concerns a Milchflußüberv achung when milking cows, by the falls below a minimum amount of ca, 0.2 kg milk / min, an optical or auditory control device is turned on _o

Characteristic of the known technical solutions

Such control organs are known from DE-OS 22 00 T41 in connection with milk flow monitoring and consist, for example, of a shut-off device for the pulsator and an electric lamp which lights up as soon as a minimum quantity of oil has fallen below If necessary, the pulsator also switches off at a later time * Thereafter, an individual treatment of the cow can take place when the pulsator is switched on again by hand.

The ridiculous part of this procedure consists in the fact that - depending on the shutdown time of the pulsator - the cow is not 'milked out'. When the pulsator is restarted, which should be avoided, the milk flow must continue to be monitored manually "while" Phase of the milking process ρ which is a period of 1 to 3 lain, the milk flow in the individual cows can be very different,

The control organs used hitherto only indicate the first drop below the minimum milk quantity. Therefore, the time of leaching of the animals is not fixed. d, h _e , -the milking process' Completed / either too early or too late, either a re-milking with reconnection of the pulsator is required, or there is a blind milking. ....

Object of the invention

It is the object of the invention to provide milk flow monitoring. Milking of cows is used by means of which a continuous, complete milking out of the cow's udder is possible. .- ""

Explanation of the invention of the invention '- ...

The invention has for its object to provide a Milchflußüberwachung in milking cows - and an apparatus for performing the method - to create in which the. Pulsa 'gate will not shut down until the cow has been completely milked out, too,' Yieixn. over a certain period, the Milchflußmenge adopted as the minimum amount uiitex-steps _o

The object of the invention wird.nun achieved in that through the controlling of the first falling below the minimum, amount over a definable period of time, ^'preferably: be switched on 30 sec j preliminary signals and after completion thereof a continuous signal and at a intermediate Überschreitung- This minimum quantity is the timed. Pre-signal is interrupted ₀ . '

For apparatus for carrying out the method, an electric lamp is provided as an optical control element.

The distant signal "is ₉ that the electric lamp each blink, the milk flow .solange the minimum limit again schreitete If the Gesamtvorsignalzeit, that the milk flow lake for a total time of about 30, below the set minimum amount, a continuous signal appears This continuous signal can therein exist that the lamp, for example, indicates a steady light.

Of course, other controls are possible, e.g. a green light at the pre-signal and a red light at the continuous signal.

This milking method in conjunction with an optical or; Acoustic control device has the advantage in particular in a manual Absehalteinrichtung the pulsator or the milking system that the milker is made early by a warning signal to the fact that the final phase of the milking process has begun and the Dauersignal.der milking. is finished and the system can be switched off early.

In connection with an automatic automatic switch-off, which can be controlled ₉ that after reaching the set Vorsignalzeit the system also automatically switches off, the milker can be made aware by the advance signal that the final phase of the milking process has begun. If necessary, the milker can provide milking aids before switching off the pulsator. ^:

Berlin, d.19.2.1979 54 803 24

By, this method is once a blank milking and continue a Machmelken largely avoided. Of course, another control device can be provided, which activates a warning signal when the minimum quantity of milk is higher than that defined.

embodiment

The invention will be explained in more detail with reference to an embodiment. In the accompanying drawing show:

Fig. 1: the flow of milk flow in the milking process in a graphical representationi

2: the final phase of the milk flow in a graphical representation

Pig. 1 shows the milk flow during the milking process, which rises sharply at the beginning of the milking process * and slowly decreases after reaching a maximum value at intervals «

In lig. 2 is the final phase of milk flow, which may extend over a period of 1 to 3 minutes, shown in more detail.

In the drawing, in the example, the lower minimum limit is defined as a milk flow of 0.2 kg / min. The first time this 0.2 kg / min limit is undershot, a pre-signal, e.g. via a flashing of an electric lamp, which is present in the aforementioned example, first over a period of 5 see and then extinguished when Wiederäberschreiten the minimum limit of the milk flow and only lights up again when this minimum limit is reached again.

Berlin, d.19.2.1979 54 803 24

In the aforementioned example, the O 2 kg / min limit is exceeded 5 times over a period of 5, 3, 8, 10 and 4 seconds. During this time, the lamp flashes and goes out during the period when the 0.2 kg / min limit is exceeded. After reaching a fixed total pre-signal time of e.g. 30 see below, in which the 0.2 kg / min limit is exceeded, a continuous signal, e.g. a steady light.

It is also conceivable that after turning on the continuous signal, a timer is turned on, which indicates the milking the time elapsed after completion of the pre-signal time each time.
