Description

The The invention relates to a milking device handling device for a milking stall of a milking parlor.

A generic milking device-removal device and a generic method are known from WO 2004/23866 as well as parallel to this document, based on the same priority patent applications known.

The invention has the object, starting from the generic device of WO 2004/23866 whose solution has proven itself to further improve the handling of the milking device removal device and simplify.

The Invention solves this problem by the subject matter of the claim 1.

advantageous Embodiments of the invention are in the subclaims where.

claim 1 provides a handling device for handling milking parlor, with a holding device for the milking machine, on the one pivotable service arm is arranged, whose to the holding device pointing end via a hinge with the holding device is connected, which has a rotation axis and on which a traction means is movably guided, on which hung the milking is, wherein the effective length of the traction means by means of a reducible means acting on the traction means is.

These Design has several advantages. By means of the invention possibility created, the effective length of the To reduce traction means can constructively such a length the traction device can be selected, with which it can be ensured that on the milking machine attached to the udder of a dairy animal no vertical forces and no horizontal forces by the handling device during the milking process Act. Furthermore, by a sufficient length of the By means of the milker not in his work when applying the milking parlor with special needs. On the other hand, the length of the traction device in be reduced to a lowered position, so that the milking machine not can touch the ground. This will be in the course of the further Explanations explained in detail.

following the invention will become more apparent with reference to the drawing described. It shows:

1a a view of a handling device for milking in a milking position;

1b a side view of the handling device 1 with hidden side cover in the milking position;

2a , b to 4a , b the handling devices 1 in further handling positions;

5a , b the handling devices 3 with a reduction device according to the invention in an activated state.

1 shows a handling device for milking to milking a dairy animal, which is a holding device 1 for milking equipment, which is designed to be arranged at a milking stall, not shown here, of a milking parlor, which has at least one or more milking parlors, each with a holding device 1 are provided. The holding device 1 serves primarily to hold a service arm 2 , But it can also take on additional functions. In particular, it may be designed like a cabinet and an electronic control system 20 record (see 1 ) and it can also be designed as part of a barrier between the milking stations.

The milking parlor is designed according to a particular preferred embodiment as a milking carousel - in particular as an outdoor milking carousel - with a plurality of milking stations. An external milking carousel, on which the handling devices in the manner of 1 to 5 can be arranged, is exemplary in its own generic WO 2004/23866 shown. In such a Außenmelkkarussell the cows are directed with their heads radially inward. 1a shows a view from an area outside the outer periphery of the milking carousel to the handling device for the milking machine.

The The invention is not for use on such a rotary milking parlor limited, but also on other types of milking parlors z. B. with a series of juxtaposed milking stalls used.

Regarding the basic handling of the milking parlor in milking is also on the already mentioned WO 2004/23866 directed.

On the holding device 1 the handling device is the service arm 2 arranged, whose to the holding device 1 pointing service arm end 21 movable, preferably via a swivel joint 3 swiveling, with the holding device 1 connected or arranged at this.

The swivel joint 3 here has a central pivot (not visible here), which is immovable with the holding device 1 connected is and a rotatable sleeve rotatably mounted on the pivot 4 which the actual service arm 2 wearing.

A preferably rotatable milking parlor floor on which the holding device 1 is arranged, bears the reference numeral 5 ,

The swivel joint 3 also has an axis of rotation R, which is oriented at an angle to the vertical Z, wherein the angle α between the vertical Z and the axis of rotation R are preferably between 10 ° and 60 ° (see 1a and 1b ).

A means of several guide means, for example by means of the service arm 2 attached eyelet 6 , guided traction means, for example a traction cable 7 or a chain, carries the milking machine 8th with a milk collection piece 9 and several milking cups 10 as well as the respective milking cups 10 with the milk collecting piece 9 connecting short milk tubes.

This is the pull rope 7 with its one end on or near the milk collector 9 attached, runs from there through the eyelet 6 outside on the service arm 2 up to an opening 12 in particular a single or multi-part pipe 13 through which the pull rope 7 inside the holding device 1 is guided.

The inside of the holding device 1 arranged cylinders 14 - in the following as acceptance cylinder 14 indicates - has a guiding function performing lid part 15 on, over which the pull rope 7 into the interior of the acceptance cylinder 14 is guided. Inside the removal cylinder 14 is the pull rope 7 with its other end (not shown) fixed to a movably mounted in the take-off cylinder sleeve working piston (not shown). At the lead of the pull rope 7 is still one within the fixture 1 arranged leadership role 16 involved.

The arrangement shown and described by way of example essentially makes it possible to handle the milking cluster 8th , where the milking machine 8th , is spent in different handling positions depending on a respective milking operation.

So corresponds to the in 1 shown handling position of a so-called milking position, the in 2 shown further handling position of a so-called removal position, 3 shows the milking in a lowered hand handling position (lowered position) in the service arm 2 protrudes radially outward beyond the edge of the milking carousel and the milking cluster 8th in the direction of the milking carousel floor 5 is lowered and 4 shows a presentation for the milker. The orientation of the milking cluster 8th can also be different than shown in the figures. So is in 3 and 5 in each case a so-called backflush orientation shown, in which the milking machine can be flushed with this function. The traction means could each - without backflush - but also at the attachment point 22 attack. However, this is not essential to this invention.

Because the milking machine 8th firmly with the pull rope 7 connected, must be the length of the pull rope 7 be sized so that when the milking machine 8th in the in 1 shown milking position, preferably no tensile forces on the milking parlor located on the udder 8th Act. Furthermore, the length of the pull rope must 7 be sized so that the milker picking up the milking parlor 8th from the presentation position (cf. 4 is not hampered in his work and the milking parlor 8th also unhindered to attach to the animals to be milked.

In contrast, the length of the pull rope may 7 but also not be too long, otherwise the milking machine 8th when in the in 3 shown handling position is lowered, touched due to the large length of the ground outside the carousel. This is to be avoided, since in this case the milking machine 8th can be contaminated and / or damaged.

In practice has so far led to the choice of a so-called "compromise length", which is not satisfactory.

The invention therefore proposes the effective length of the pull rope 7 by means of a pull rope 7 to reduce acting reducing means, for example by means of an additional reduction cylinder, and preferably in each case during the milking operations, during which the milking 8th is lowered into a handling position in which there is a risk that the milking machine 8th comes into contact with the ground outside the carousel.

Under the effective length of the pull rope 7 is the length of the pull rope 7 to understand what the range of motion of the milking parlor 8th sets.

In 5 is the reduction device according to the invention 17 , here with a reduction cylinder 17a , shown in an active ie a "length reducing" state. The reduction cylinder is for example by means of a piston rod 18 or rope and a connecting means 19 , For example, a towing eye, detachable with the pull rope 7 connected so that the pull rope 7 free through the drawbar eye 19 can slip through. The action on the pull rope preferably takes place 7 , as in 5 shown, between rule the lid part 15 of the take-off cylinder 14 and the leadership 16 , In the context of the invention, however, other action points are conceivable.

Detects a control unit, not shown, for controlling the milking a Melkarbeitsschritt in which the milking 8th is to be lowered into a handling position in which there is a risk that the milking machine 8th comes into contact with the ground outside the carousel, so the control means acts on the reduction cylinder 17a with vacuum, such that this "length-reducing" on the pull rope 7 acts. Subsequently or simultaneously, the acceptance cylinder 14 ventilated and the milking parlor 8th can be lowered into the lowered handling position. The reduction cylinder 17a is preferably in the interior of the holding device 1 arranged.

Alternatively (not shown)), the reduction device 17 also by means of a roller with the traction means 7 be connected, wherein the traction means 7 is placed around the role.

In this way, a method for handling a handling device is realized in each case in a simple manner, in which the effective length of the traction means 7 by means of a reduction device 17 is reduced.
