- such a distribution device usually has a provision element in which the fluid to be distributed is stored or made available, and additionally a special distribution head through which the actual distribution of the fluid is carried out.
- a distributor head of the distributor device When distributing the fluid, it is introduced from the supply element into a distributor head of the distributor device and is distributed over the surface by the distributor head, the fluid being able to be distributed over a greater width in particular through the distributor head.
- the fluid can be distributed over a large area in a time-saving manner.
- the fluid introduced into the distributor head is often divided into a large number of mostly juxtaposed distributor openings and this enables an at least rudimentary flat distribution of the fluid on the surface.
- the fluid is introduced into the distributor head and fanned out in this to a greater width for distribution on the surface.
- this mostly has a fluid volume, ie a flea space for receiving fluid, with which both a filling opening for filling the fluid into the fluid volume and the Ver distributor openings are connected in a fluid-communicating manner.

- a distributor head as part of a distributor device, fluids can be distributed evenly on a surface.
- the distributor head has, in particular, an elongated base element in which a fluid volume is arranged, in which the fluid can be received in the interior of the distributor head.
- the fluid can be introduced into the fluid volume of the distributor head through the remaining components of a distributor device, for example a provision element for providing the fluid to be distributed.
- the distributor head has a filling opening which is connected in fluid communication with the fluid volume. In addition to a single filling opening, two or more such filling openings can also be provided.
- At least one distributor opening is in turn connected to the fluid volume in a fluid-communicating manner, whereby the fluid can be discharged from the fluid volume onto the surface.
- a liquid adhesive and / or adhesive can be used, in particular a special liquid adhesive and / or adhesive with high viscosity.
- Each of the at least one distributor opening represents an opening in a wall of the fluid volume and has a length and a width.
- the length of the respective distributor opening is understood to be a length through which the fluid flows along a flow direction of the fluid in the distributor opening.
- the length of the respective distributor opening can correspond to a wall thickness of the wall of the fluid volume at the location of the distributor opening.
- a width of the respective distributor opening in the sense of the invention is a clear width of the distributor opening transversely to the length through which the flow passes.
- slot-like distributor openings which, according to the invention, are designed to be slit-like or gap-like along a longitudinal direction of the second longitudinal side
- the width of this distributor opening in the sense of the invention is also oriented transversely to the slot-like extension of this distributor opening in addition to the alignment transverse to the direction of flow or the length through which the flow passes .
- these slot-like distributor openings can preferably be viewed as a continuous series of possible exit locations, each of these exit locations being able to have an individual length and / or width.
- the at least one distributor opening is arranged in a second longitudinal side of the distributor head. In this way, the fluid can be discharged or distributed over the at least one distributor opening onto the surface in a particularly simple manner.
- the filling opening for introducing the fluid into the fluid volume can preferably be arranged in a first longitudinal side which is arranged opposite the second longitudinal side.
- the fluid is in through the filling opening on a first longitudinal side of the base element or the fluid volume the fluid volume is introduced, is distributed therein and is then distributed on the surface via the at least one distributor opening arranged in the second longitudinal side.
- Internal distribution of the fluid in the fluid volume can thus be achieved particularly easily and effectively by this arrangement of the filling opening in the first longitudinal side and the large number of distributor openings in the second longitudinal side.
- the at least one distributor opening is formed continuously in a wall of the base element. Continuous within the meaning of the invention means in particular that a first open end of the at least one distributor opening is fluidly connected to the fluid volume and a second open end of the at least one distributor opening is connected to the surroundings of the distributor head in fluid communication. A discharge or distribution of the fluid through the at least one distributor opening can be ensured particularly easily in this way.
- the at least one distributor opening is formed by a plurality of distributor openings, the plurality of distributor openings being arranged adjacent to one another, particularly preferably linearly next to one another.
- the individual distributor openings in the wall of the base element each have a defined length along a direction of flow of the fluid and a defined width transversely to the corresponding direction of flow of the fluid.
- Such a defined width can be, for example, a diameter of a cylindrical or tubular distributor opening. According to the invention, it is provided that these lengths and / or widths of the distributor openings are not the same for all distributor openings, but rather are designed to vary over the plurality of distributor openings.
- This pressure distribution in particular the pressure in the fluid at the connection point of the respective distributor opening with the fluid volume, is decisive in particular for an amount of fluid that exits through the respective distributor opening.
- a higher pressure is present than at distributor openings that are further from the at least one filler opening removed to are arranged, whereby the flow direction of the fluid in the respective distribution opening is increasingly oriented transversely to the flow direction of the fluid in the fluid volume.
- This pressure behavior of the fluid in the fluid volume is also referred to below as “effective pressure”. At a high effective pressure, however, more fluid emerges from the respective distributor opening in the same unit of time than would emerge at a low effective pressure.
- effective pressure At a high effective pressure, however, more fluid emerges from the respective distributor opening in the same unit of time than would emerge at a low effective pressure.
- the lengths and / or widths of the distributor opening are varied in such a way that precisely these different pressure distributions in the fluid volume are compensated for. Overall, in this way, a uniform application of the fluid to the surface can be provided.
- such a uniform application of the fluid to the surface can also be provided in that at least one of the at least one distributor openings is shaped as a slot-like distributor opening, the slot-like distributor opening extending along a longitudinal direction of the second longitudinal side and a length of the slot-like one Distributor opening along a flow direction of the fluid and / or a width of the slot-like distribution opening are designed to vary transversely to the flow direction of the fluid and transversely to the longitudinal direction of the second longitudinal side for a uniform or at least substantially uniform fluid distribution on the surface when distributing the fluid.
- this at least one distributor opening extends as a slot-like opening along the longitudinal direction of the second longitudinal side and thus provides the fluid with a continuous row of outlet locations along the longitudinal direction.
- a slot-like distributor opening can thus also be viewed as a fusion of a plurality of directly merging distributor openings, as described above, with all the features and advantages listed there.
- a single slot-like distributor opening of this type is particularly preferably provided, which extends over the entire or at least substantially the entire length of the second longitudinal side of the distributor head.
- a length of the slot-like distributor opening changes along a flow direction of the fluid in the distributor opening and / or a width of the slot-like distributor opening transversely to the flow direction of the fluid and transversely to the longitudinal direction of the distributor opening changes, in particular changes such that the above-described changes Differences in the flow of the fluid in the fluid volume, for example in relation to a
- the distance to be covered between the filling opening and the respective exit point of the fluid can be compensated for by the slot-like distributor opening or in relation to pressure conditions and / or flow velocities in the fluid.
- distribution elements for uniform or at least essentially uniform distribution of the fluid in the fluid volume can be arranged in the interior of the fluid volume for uniform or at least essentially uniform fluid distribution on the surface when the fluid is distributed through the at least one distribution opening.
- distribution elements can be designed, for example, as guide surfaces, channels and / or also as blocking elements for the targeted guiding of a flow of fluid in the fluid volume.
- a distributor head according to the invention can preferably be designed in such a way that the length and / or the width of the at least one distributor opening are designed so that they are adapted to the position of the at least one filling opening.
- the pressure distribution described above in the fluid will develop as a function of the position of the at least one filling opening in the fluid volume.
- An adaptation of the length and / or the width of the at least one distributor opening Regardless of whether it is a distribution opening of a large number of distribution openings or a configuration of a slot-like distribution opening at one or more outlet locations, the required variation of the length and / or width of the at least one can be made particularly easily at this position of the at least one filling opening Effect distribution openings to compensate for the different effective pressures within the fluid present in the fluid volume. Even an at least partially incomplete filling of the fluid volume with fluid at the beginning of the use of a distributor head according to the invention can be compensated or at least partially compensated in this way by a correspondingly provided variation in the length and / or width of the at least one distributor opening.
- a distributor head according to the invention can be designed in such a way that the length and / or the width of the at least one distributor opening are designed to be adapted to a distance between the at least one filling opening and the respective distributor opening.
- a distance between the respective at least one filling opening and the position of the corresponding distributor opening or an outlet location of a distributor opening at which a length and / or width of the distributor opening is to be varied can be used to determine the above-described pressure distribution in the fluid in the fluid volume or to estimate this at least in part.
- the length of the at least one distributor opening increases with the distance between the at least one filler opening and the respective distributor Opening are designed to decrease.
- the pressure distribution in the interior of the fluid volume is usually designed such that the pressure is highest at the locations of the at least one distributor opening in the fluid close to the filling opening. In other words, this pressure in the fluid decreases with increasing distance from the filling opening. As already described above, this can be attributed, for example, to an angle to be taken between a flow direction of the fluid in the fluid volume and in the at least one distributor opening arranged at the corresponding distance.
- the respective length of the at least one distributor opening becomes shorter with increasing distance from the at least one filling opening.
- the lengths of the distributor openings that are arranged further away from the at least one filler opening are shorter than the lengths of the distributor openings that are closer to the at least one filler opening.
- at least one distributor opening which is preferably slit-like in the direction of a longitudinal extension of the second longitudinal side, a length through which the fluid flows through the slot-like distributor opening can change accordingly in such a way that the length through which the flow passes as the distance between the respective outlet point and at least one filling opening increases decreases.
- Fluid that enters the corresponding distribution opening at high pressure near the filling opening thus has to cover a further path in the respective distribution opening or at the respective exit point within the slot-like distribution opening, whereby the fluid can be discharged through this special distribution opening or at this special exit point is delayed.
- the pressure in the fluid Far away from the filling opening, the pressure in the fluid is lower, but the length of the corresponding distributor opening or a length at the corresponding exit location within the slot-like distributor opening is shortened accordingly. In this way, in particular, the even distribution of fluid on the surface when the fluid is distributed can be ensured.
- a low effective pressure prevailing there in the fluid can be compensated for by a large width of the distributor openings further away from the filling opening.
- a width of the distributor opening transversely to the fluid direction and transversely to the longitudinal extension along the longitudinal extension of the slot-like distributor opening can change accordingly in such a way that the width as the distance between the respective outlet point of the fluid through the slot-like distributor opening to at least one filling opening increases increases. This also leads to a uniform or at least essentially uniform fluid distribution on the surface when the fluid is distributed.
- a distributor head according to the invention can be designed such that the distributor head has two, three or more filling openings, the two, three or more filling openings preferably being arranged in the first longitudinal side of the distributor head.
- fluid can be introduced into the fluid volume at two, three or more points at the same time.
- this results in a more uniform pressure distribution in the fluid volume than when the fluid is introduced into the fluid volume only through a single filling opening.
- a stand of the individual distributor openings of a plurality of distributor openings to the filling opening closest to it can be reduced, whereby differences in the effective pressure at the locations of the respective distributor opening can also be reduced.
- a distributor head according to the invention can be designed in such a way that the distributor head has two mutually opposite end sections as the end of the first longitudinal side and the second longitudinal side, a disk-like spacer element being arranged on each of the end sections, and the disk-like spacer elements at least the second longitudinal side Protrude from the distributor head.
- these spacer elements can be used at the opposite end sections of the first longitudinal side and the second longitudinal side in order to place the distributor head on the surface to be wetted with the fluid, while at the same time preventing the at least one distributor opening from contacting the surface occurs.
- There is thus a defined distance between the at least one distributor opening voltage and the surface are maintained, so that the fluid can exit unhindered from the at least one distributor opening.
- contamination of the at least one distributor opening by elements of the surface can be reliably avoided in this way.
- a distributor head according to the invention can furthermore be designed in such a way that the disk-like spacer element is rotatably mounted on the respective end section.
- the disk-like spacer elements can function as wheels when the distributor head or the corresponding distributor device is shifted, in particular linearly, when the fluid is applied to the surface. In this way, a particularly safe and controlled application or distribution of the fluid to the corresponding surface can be achieved.
- the disk-like spacer elements can be circular or cylindrical for this purpose.

- the conveying element 16 also has a drive rod (see Fig. 7), which is coupled to two drive rods that protrude into the fluid container 18 or the hollow receiving tubes and are connected to the pistons, in order to move a drive of the conveying element 16, for example one Electric motor, ultimately transferred to the piston.
- the distributor head 20 comprises a base element 30 which has an at least essentially triangular cross section 36 (see FIG. 7).
- a first longitudinal side 22 of the distributor head 20 which is formed by the rear of the base element 30, two filling openings 50 are arranged, which can be connected to the fluid-communicating containers 18 (not shown) shown in Fig. 1 Fluidbe.
- the fluid 70 (see FIGS. 6 and 7) from the fluid containers 18 is inside the green elements 30 distributed and distributed over a plurality of distributor openings 60, which are arranged in a second longitudinal side 24 of the distributor head 20, on a surface 80 (see FIGS. 6 and 7).
- the second longitudinal side 24 is arranged in a connecting area 44 of a first wall element 38 and a second wall element 40 (not shown) (see FIGS. 4, 5 and 7).
- At opposite end sections 26 of the distributor head 20 are preferably rotatably mounted spacer elements 28 which protrude at least the second longitudinal side 24.
- spacer element 28 when the distributor head 20 is placed on the upper surface 80, a distance between the surface 80 and the distributor openings 60 can be ensured.
- the distributor head 20 according to the invention can have a preferably movable closure element 66, by means of which individual distributor openings 60 can be selectively closed.
- Fig. 3 shows the distributor head 20 shown in Fig. 2 in an exploded view. It is clearly visible that the first longitudinal side 22 in this embodiment of the distributor head 20 according to the invention is formed by a third wall element 42, the two filling openings 50 being spaced apart from one another essentially centrally in this third wall element 42.
- the third wall element 42 can be arranged on the first wall element 38 and on the non-visible second wall element 40, preferably in a sealed manner, in order to enclose the fluid volume 32.
- the first wall element 38 and the second wall element 40 are formed in one piece, preferably monolithically, with the distributor openings 60 necessary for discharging the fluid 70 being arranged in their connecting area 44.
- the connecting area 44 forms a second longitudinal side 24 of the distributor head 20 according to the invention.
- the first wall element 38 and the second wall element 40 can be made of plastic Consist of material and preferably be manufactured as an injection molded part.
- the third wall element 42 can also consist in particular of plastic and preferably be manufactured as an injection molded part.
- FIG. 4 and 5 show two possible embodiments of a distributor head 20 according to the invention, in which the inventive principle of a variation of a length 62 and / or width 64 of the respective distributor openings 60 is implemented differently.
- the fluid volume 32 has an at least essentially triangular cross-section 36 (see FIG. 7), with only the first wall element 38 and the second wall element 40 connected in one piece and / or monolithically being shown are.
- the fluid volume 32 extends in particular within the base element 30 of the distributor head 20 between the two end sections 26 of the distributor head 20.
- the distributor openings 60 are each arranged in a wall 34 of the base element 30, this wall 34 being in the connection area 44 between the first wall element 38 and the second wall element 40 as the second longitudinal side 24 of the distributor head 20 extends. Furthermore, the filling openings 50 are indicated in each of the two figures.
- FIG. 4 an embodiment of a distributor head 20 according to the invention is shown, in which in particular the lengths 62 of the distributor opening 60 are designed so as to be adapted to the respective position 52 of the filler openings 50. It is clearly visible that in particular the lengths 62 of the distributor openings 60 decrease with increasing distance 54 from the respective filling openings 50. In other words, the distributor openings 60, which are closer to the filling openings 50, have a greater length 62 than the distributor openings 60, which are further away from the filling openings 50.
- distributor openings 60 of greater length 62 are provided than in regions further away from the filling openings 50, where distributor openings are arranged with a shorter length 62 in the wall 34. In this way, the various pressure conditions in the fluid 70 in the fluid volume 32 can be balanced. It is also particularly clearly visible that if two filling openings 50 are provided, as in the embodiment shown, this is also reflected in the lengths 62 of the distributor openings 60 or their variation.
- the differences described above in the effective pressure of the fluid 70 in the fluid volume 32 can also be compensated for by varying the width 64 of the distributor openings 60. This is shown in FIG. 5, where it is particularly visible at that the widths 64 of the distributor openings 60 also increase with increasing distance 54 from the filling openings 50. Here, too, it can be seen that the presence of two filling openings 50 is also reflected in the variation of the width 64 of the distributor openings 60.
- FIG. 6 shows a distributor device 10 according to the invention distributing a fluid 70 onto a surface 80.
- the distributor openings 60 are arranged in a connec tion area 44 which is opposite the first longitudinal side 22 of the distributor head 20, which is formed by the third wall element 42.
- At end sections 26 of the distributor head 20 rotatably mounted spacer elements 28 are again arranged, whereby a uniform application or movement of the entire th distributor device 10 when applying the fluid 70 to the surface 80 can be achieved particularly easily.
- the fluid 70 is transferred from the two fluid packs 19, which are arranged in the fluid containers 18 and designed as flexible bags, into the fluid volume 32 of the ground. delements 30 pressed.
- the base element 30 is connected in fluid communication with the two fluid containers 18 via the filling openings 50.
- the fluid 70 is distributed in this fluid volume 32 along a flow direction 72.
- the flow direction 72 of the fluid 70 in the fluid volume 32 close to the filling openings 50 is at least essentially in the direction of the distribution openings 60 shows, further away from the filling openings 50, however, is aligned transversely to these. This makes it clear that a higher effective pressure will be established in the fluid 70 near the position 52 of the filling openings 50 than away from this position 52.
- the lengths 62 are therefore those in FIG second longitudinal side 24 of the distributor head 20 provided distribution openings 60 depending on the distance 54 of the respective distributor opening 60 from the position 52 of the filling opening 50 formed varying.
- FIG. 7 shows a further sectional illustration of a distributor device 10 according to the invention when a fluid 70 is applied in a flow direction 72 to a surface 80.
- the entire distributor device 10 moves in a distributing direction 82, this being made possible particularly easily by the rotatably mounted spacer elements 28.
- the fluid 70 is introduced from the fluid containers 18 via the filling opening 50 into the fluid volume 32 of the distributor head 20 and leaves this along the flow direction 72 through the multiplicity of distributor openings 60, which are provided in the second longitudinal side 24 of the distributor head 20, which is designed as a connecting area 44 .
- the base element 30 and thus also the fluid volume 32 has a triangular or at least substantially triangular cross section 36.
- This cross section 36 is formed in particular by the first wall element 38 and the second wall element 40, which is formed in one piece and / or monolithically therewith.
- the first and second wall elements 38, 40 enclose the connecting area 44, which forms the second longitudinal side 24 of the distributor head 20 and, in particular, in particular, the plurality of distribution openings 60 carries.
- the third wall element 42 which is used as the first longitudinal side 22 of the distributor head 20 for arranging the filling opening 50, is arranged opposite the connecting region 44.
- a distributor head 20 can of course also be connected to only a single fluid container 18 or to more than two fluid containers 18.
- Such a distributor head and such a distributor device also fall under the present inven tion and have the advantages mentioned with reference to the exemplary embodiment described. All of the structural and functional features described are also applicable to such modifications.
- a further embodiment of a distributor head 20 is shown.
- the distributor head 20 is equipped with a single distributor opening 60, this distributor opening 60 being designed like a slot and extending over the entire or at least substantially the entire second longitudinal side 24 in the longitudinal direction 74 thereof. It is clearly visible that this distributor opening 60 has a width 64 that is variable along the longitudinal direction 74. Overall, the width 64 of the slot-like distributor opening 60 increases with increasing distance 54 from the two filling openings 50 or their positions 52.
- the inner differences already described above in the fluid 70 to be distributed in the fluid volume 32 of the distributor head 20 can also be at least partially, preferably completely, compensated in this way.
- a uniform application of the fluid 70 onto a surface 80 can thus also be provided with a correspondingly configured slot-like distributor opening 60.
- 9 shows an alternative or additional embodiment of an internal structure of a distributor head 20 according to the invention in a sectional illustration.
- the water distributor head 20 also has two filling openings 50 and a large number of distributor openings 60.
- guide elements 46 are arranged in this embodiment of the distributor head according to the invention. As shown, these guide elements 46 can be designed, for example, as guide surfaces, which preferably radiate out from the respective filling openings 50. In this way, a uniform distribution of the fluid 70 can already be achieved or at least supported in the interior of the fluid volume 32.
- the fluid 70 can then be discharged through the multiplicity of distributor openings 60 in a particularly simple manner and evenly over the entire width of the distributor head 20.
