Robert Bürkle & Co., machine factory, 729 Freuden Stadt / Württ. ~ \ Watering head on liquid pouring machine.

The utility model relates to a pouring head on a liquid pouring machine for a free-falling flow curtain.

Watering heads for free-falling flow curtain with one-sided open free Drainage areas are known per se. They work according to the so-called overflow principle and require very precise adjustment in the Horizontal special facilities to achieve an absolutely even application of liquid to the workpieces. Will with it Equipped machines at the installation site are impaired in the accuracy of their "i horizontal position by environmental influences, so

the uniformity of the order is adversely affected.

According to the invention, this disadvantage is avoided in a pouring head of the type mentioned at the outset in that it has a liquid drainage bar has, which is formed with a drainage edge for the detachment of the free-falling flow curtain, and one of the drainage bar or has the dosing strip assigned to the pouring head part that receives it.

This combination of features makes the drainage area independent of external influences and also regardless of the behavior of the liquid level in the inside of the pouring head in the entire area of its extent exactly the same amount of liquid is supplied.

Thus there is also a certain deviation of the casting head from the horizontal position without affecting the quality of the liquid application.

The invention is illustrated below with reference to the drawing of some exemplary embodiments explained.

Show it :

Fig. 1 the watering head with the bottom, forming the flow curtain Long slot,

and 3 a variant of the pouring head and

4 shows a further variant in which the longitudinal slot is arranged laterally is .

In all the exemplary embodiments, hinged casting heads are shown which are equipped with drainage strips 1 or 2 or 3 and with metering strips 4 or 5.

Äbiaufträger and dosing strips can together create a long slot ben. However, it is also conceivable that the metering strip on the wall of the

Giefikopfteiies 8 is pending and already with this together the long slot forms (see Figs. 1-3).

The casting heads are fed through the feed lines 7, with their Exit point in the interior of the casting head a deflector 8 or 9 is assigned. The drainage bar 1 is in the exemplary embodiments 1-3 attached to the movable pouring head part 6 and, in the exemplary embodiment of FIG. 4, arranged on the fixed pouring head part 6 *. Accordingly the metering strip 4 is attached to the stationary pouring head part 10 in the exemplary embodiments 1-3. In the embodiment of Figure 4 is used to take on of the dosing strip 5, the pivoting cast head part 11.

The two casting head halves are hinged to the axis 12 and 13, respectively.

In the embodiment according to FIG. 1, the drain bar is a fixed one angular component. The horizontal leg is attached to the pouring head part 6, while the vertical leg is attached directly adjoins one of the inner surfaces of the watering head. In FIGS. 2 and 3, too, the drainage strip is angular, but it is an elastic one Machine part. Its vertical leg that forms the drainage surface can be elastically deflected from its tension-free vertical position by readjusting a bridge 14 by means of screws and nuts 15.

The function of the long slot nozzle can also be influenced by the angular position (of the run-off surface 2. By the run-off speed

to be able to slow down the liquid on the progress bar 2 slightly and thereby better remove or dissolve in the liquid air bubbles possibly contained, it will be the run-off surface 2 by a certain angular amount from the vertical herau-s-swivel _s In order of a hinge to To be able to dispense with the connection point of the drainage surface to the watering head, the drainage surface 2 with its fastening surface 16 is designed to be resilient. In this way, for the first time, even when the position of the drainage surface 2 is changed, a completely continuous transition between the inner surface 17 and the side of the drainage surface 2 exposed to the liquid is achieved.

In the exemplary embodiment in FIG. 4, the interior of the pouring head is emptied After the end of work, a return line 18 is attached.

Fig. 1 shows the movable pouring head part in the swiveled up position 6 "
