Description

[0030] In view of the aforementioned advantages of the dispensing device, this is preferably to be used for filling artificial turf surfaces with sand and/or granulate.

[0031] In the accompanying drawings, the invention is shown in schematically in two particular exemplary embodiments.

[0032] FIG. 1 shows a longitudinal side view of an exemplary embodiment of a dispensing device according to the invention, and

[0033] FIG. 2 shows a side view of a second exemplary embodiment of a dispensing device according to the invention.

[0034] In the figures, identical or corresponding elements are each identified by the same reference characters and therefore will not be described again unless necessary. FIG. 1 shows a longitudinal sectional side view of a first exemplary embodiment of an inventive dispensing device 10 for filler material onto a surface to be filled, in particular of sand for artificial turf surfaces, which is outfitted with a main frame 11 and a conveying belt 20 guided thereon for delivering the filler material to two output portions 21, 21′. Said output portions 21, 21′ are formed on a left and right deflection roller 22, 22′, at which the filler material falls freely downward either to the left or right depending on the direction of travel of the dispensing device 10 onto the surface to be filled. Metering means 32, 32′ mounted respectively in the vicinity of the deflection rollers 22, 22′, which metering means 32, 32′ are formed in this embodiment as adjustable slides, form a corresponding gap with the conveying belt 20, said gap enabling a volume regulation of the outputted filler material. The filler material, such as sand and/or granulate, is delivered here through a grate 42 to a funnel-shaped hopper 40 and stored therein, whereby the first clumps of the filler material, which is possibly still wet from a washing process, are dispersed. The filler material is delivered to the conveying belt 20 via V-shaped mutually adjoining guide plates 41, 41′ in the respectively selected direction of transport.

[0035] If, for example, the dispensing device shown here is moved to the left by means of a traction device 51 via its chassis 50, 50′, the left output portion 21 is active, meaning that the filler material slides along the guide plate 41 onto the conveying belt 20, where it is flatly aligned. It then falls freely downward over the deflection roller 22, where in the direction of travel it comes to lie in front of two successively arranged distribution brushes 30, 30′, which in turn distribute it again across the surface to be filled. The distribution brushes 30, 30′ hereby perform a rotational, in particular oscillating, rotary movement about a vertical axis, which ensures a particularly efficient distribution of the filler material. In sum, a highly uniform distribution of the filler material on the surface to be filled, the fill height of which filler material can additionally be regulated by means of the metering means 32, is thereby ensured via the grate 42, the conveying belt 20, the output portion 21 and the distribution brushes 30, 30′. This applies in the same way for a direction of travel of the dispensing device 10 to the right, in which the output portion 21′ is active, meaning that the filler material is delivered via the guide plate 41′ and the conveying belt 20 to a gap between the metering means 32′ and the conveying belt 20, behind which it falls downward over the deflection roller 22′. Here, with a direction of travel of the dispensing device 10 to the left, the conveying belt 20 moves in a counterclockwise direction, and with a direction of travel of the dispensing device 10 to the right, the conveying belt 20 moves in a clockwise direction.

[0036] For processing different surfaces to be filled, in particular artificial turf surfaces with different pile heights, filler materials and/or fill volumes, the height of the distribution brushes 30, 30′ can be designed to be adjustable via a corresponding adjustment mechanism on the main frame 11. In this embodiment, the power supply for the deflection rollers 22, 22′ and the distribution brushes 30, 30′ should originate from a towing vehicle, in order to save correspondingly heavy energy carriers on the dispensing device 10 itself. This allows a significant increase in the volume of carried filler material, wherein the chassis 50, 50′ is designed such that the highest possible maneuverability of this volume of filler material is particularly easy in both directions of travel.

[0037] FIG. 2 shows a side view of a second embodiment of the inventive dispensing device 10′ for filler material onto a surface to be filled, which, in contrast to the previously described embodiment, comprises the raising brushes 31, 31′ arranged upstream in the direction of travel from the respective distribution brushes 30, 30′. These are driven about a horizontal axis to the respective direction of travel of the dispensing device 10′ in a rotating, in particular oscillating, manner. For example, a pile of artificial turf is thereby reliably raised before the filler material, for example in a direction of travel of the dispensing device 10 to the left, falls via the output portion 21 onto the surface to be filled between the raising brush 31 and the distribution brush 30. As already described in the first exemplary embodiment of the invention, in a direction of travel of the dispensing device 10 to the right, the output portion 21′ is active, whereby the filler material comes to lie between the raising brush 31′ and the distribution brush 30′. The raising brush 31′ also performs a correspondingly rotationally driven, in particular oscillatory movement about a transverse axis to the direction of travel of the dispensing device 10.

[0038] In further contrast to the first embodiment of an inventive dispensing device 10, the embodiment of a dispensing device 10′ represented here further shows a height adjusting device 33, via which the distribution brushes 30, 30′ and the raising brushes 31, 31′ are vertically adjustable on the main frame 11′, in order to work or process different surfaces to be filled, filler materials and/or fill volumes. For transporting and delivering the filler material to the conveying belt 20, the dispensing device 10′ has in turn a funnel-shaped hopper 40, in which this filler material is received. In this dispensing device 10′, too, metering means 32, 32′ mounted to the left and right of the funnel-shaped hopper 40 form a corresponding gap together with the conveying belt 20, via which gap a desired output volume of the filler material can be set depending on the metering means 32, 32′, which are designed as slides. Otherwise, the dispensing device 10′ shown here is likewise outfitted with a chassis 50, 50′ and a traction device 51, via which it is easily maneuverable in both directions of travel.

[0039] In principle, however, both of the above-described embodiments may also be self-propelled and/or outfitted with a main frame 11, 11′ which enables the mounting thereof or the carriage thereof on a vehicle. However, under appropriate maneuverability requirements on the dispensing devices 10, 10′, it may also be sensible to design these in a hand-operable manner. Here, an appropriate power supply for the operation of the deflection rollers 22, 22′, the distribution brushes 30, 30′ and/or the raising brushes 31, 31′ may be provided, or these may—for example in the case of smaller dispensing devices—also be mechanically coupled to a chassis of the dispensing device.

[0040] Claims filed now and in the future are without prejudice in the obtaining of broader protection.

[0041] If upon closer examination, in particular of the relevant prior art, it arises that one or the other feature is expedient for the object of the invention but is not decisively important, a formulation is, of course, envisioned even now which no longer comprises such a feature, in particular in the main claim. Even such a subcombination is covered by the disclosure of this application. It is further to be noted that the embodiments and variants of the invention described in the different exemplary embodiments and shown in the figures can be combined with one another as desired. Here, a single feature or a plurality of features can be interchanged with one another as desired. These combinations of features are likewise disclosed.

[0042] References given in the dependent claims indicate the further development of the subject of the main claim through the features of the respective sub-claim. However, these should not be construed as a waiver of the right to obtain independent, objective protection for the features of the related sub-claims.

[0043] Features which have been disclosed only in the description or even single characteristics from claims which comprise a plurality of features may be adopted at any time as of inventive relevance for distinguishing from the prior art in the independent claim or claims, even if such features have been mentioned in connection with other features or achieve particularly favorable results in connection with other features.
