Description

"Dispenser for Vermin"

The invention relates to a dispenser for Vervollmaterial on a surface to be filled, in particular of sand for artificial turf surfaces.

Artificial turf is in greater demand than ever, particularly in sports field construction, because good playing characteristics, easy care and constant playability are important criteria that an artificial turf pitch can fulfill. Such an artificial turf consists of a multi-layered system of different components. The base usually forms a substructure of gravel or asphalt, on which a damping layer (or elastic support layer) is applied. This ensures that an optimum power reduction can take place on the artificial turf. This power reduction is important for the joints of the players, as too hard artificial grass surfaces can lead to joint problems.

On this damping layer of artificial turf is rolled out. The lower part of the artificial turf is usually filled with quartz sand, the upper with rubber granulate. On the one hand, rubber granulate serves as a roll for a ball; on the other hand, it also offers players a surface that gives way and at least partially resembles natural grass. This yielding causes the (pimples) shoes the player good "grip" d. H. have a stable connection between tread area & shoe and in case of falling a part of the energy can be intercepted and discharged into the ground.

Such lawns do not require many care measures. These few are even more important because they can extend the life of the artificial turf many times over. If the rubber granulate is e.g. brushed regularly and thus distributed, a rapid wear of artificial turf fibers is prevented. Because the fuller the artificial turf is filled, the less the fibers are "attacked" d. H. damaged or restricted in its function. The artificial turf is usually filled with special machines that can disperse and brush in the sand and rubber granules. This process is especially important because it performs incorrectly - resulting in an uneven playing surface.

It is an object of the present invention to provide a dispenser for filling material on a surface to be filled, in particular of sand for artificial turf surfaces, which provides an always reliable and in particular uniform delivery of Ensures Vervollmaterials and is also very simple and easy to use.

According to the invention, this object is achieved by a dispenser for filling material on a surface to be filled with a base frame and at least one conveyor belt guided thereon for supplying the filling material to at least one dispensing section.

By filling material in the context of the present invention is meant any material suitable for incorporation into an artificial turf. Of course, this is preferably the above-mentioned rubber or plastic granules. Sand, gravel or mixtures with the rubber or plastic granules are equally included and usable.

An essential point of the dispensing device according to the invention consists in that achieved by the conveyor belt a surface promotion of the backfill material and thus a lump formation is largely excluded even before its delivery. This especially if the filling material was removed or washed while still wet and still wet. Overall, its good distribution on the surface to be filled is supported.

In the dispensing device, it is then provided that in and against a direction of travel behind the dispensing section, at least one distribution brush arranged on the base frame is provided for distributing the filling material on the surface to be filled. The areal distribution of the filling material over the area to be filled is thereby clearly supported, whereby at the same time a lump formation of the filling material is also counteracted during this process. The advantage of this configuration is that the dispensing device, irrespective of the direction of travel, can permanently dispense material, ie fill material, and can avoid turning over, for example after a web has been processed. The processing times can be significantly reduced. Also, the processing is much easier to perform, since a turning of the device can be omitted. Even with limited space, the configuration proves advantageous, since there is no need to make room for the turning process.

In a development of the dispensing device, provision is made in each case for at least one erecting brush arranged on the base frame to be arranged in and against the direction of travel in front of the dispensing section for erecting fibers of the surface to be filled. This results in a surface incorporation of the filling material into the fibers or the surface, thereby preventing the filling material from resting on the fibers, which under certain circumstances are pressed flat against the surface to be filled. This also ensures better distribution of the filling material over the area to be filled.

In a further preferred embodiment of the dispensing device, it is provided that the at least one dispensing section is formed on a deflection roller of the conveyor belt. The free fall of the already extensively aligned by the conveyor belt filling material this can be better distributed again, so that its uniform application is ensured over the surface to be filled. At the same time, such a delivery of the filling material over a deflection roller of the conveyor belt is particularly easy to implement and in particular requires no further parts for directing the material flow. Such a simple construction is not only highly reliable but also very easy to maintain. In a further preferred embodiment of the dispensing device, provision is made for a respective dispensing section to be formed on deflection rollers on both sides of the conveyor belt. Thus, it is in principle possible to apply at two points of a conveyor belt and thus - by a forward or reverse running conveyor belt - in two directions of travel of the dispenser Vervollmaterial on a surface to be filled. As a result, the dispensing device according to the invention can be handled particularly easily and moreover can be used particularly efficiently.

In a further preferred embodiment of the dispensing device, it is provided that the at least one dispensing section has a metering means for the filling material to be dispensed. Such a dosing agent allows the flexibly adjustable delivery of filling material per unit area, with which a defined installation height of the filling material can be exactly maintained. Overall, this not only its uniform distribution across the area to be filled away, but also its desired filling height can be ensured. In particular, it is also possible, a

Circulation speed of the conveyor belt to vote on a speed of movement of the dispenser that no Füllhöhenschwankungen arise.

In a further preferred embodiment of the dispensing device, it is provided that the metering means is designed as a respective slide, which forms an adjustable discharge gap with the conveyor belt. In principle, it is also possible to attach differently wide open funnels or the like, which, when replaced, allow a respective amount regulation of the filling material. By a respective slider, however, a particularly simple construction is possible because few additional parts are needed to to allow completely different volume deliveries with the sole adjustment of a single component.

In a further preferred embodiment of the dispensing device, it is provided that the conveyor belt at least partially forms a bottom surface of a funnel-shaped receiving container for the filling material. This also eliminates another component, which makes the entire construction simpler and easier. In addition, it is ensured that the conveyor belt is always reliably charged with filling material, so that no filling gaps occur at the surface to be filled.

In a further preferred embodiment of the dispensing device, it is provided that at least one guide plate is provided for feeding the filling material in the transport direction of the conveyor belt. Thus, the continuous feed of the conveyor belt with filling material is also increased, so that even with potentially low loading of the receptacle, a uniform filling of the surface to be filled is ensured.

In a further preferred embodiment of the dispensing device, it is provided that the guide plate is gable-shaped and arranged above the conveyor belt. Such a baffle is a particularly simple construction, since only a single baffle is required for supplying the filling material in the forward and backward movement of the dispenser.

In a further preferred embodiment of the dispensing device, it is also provided that the guide plate is arranged approximately centrally between two guide rollers of the conveyor belt. This ensures, in particular, an equal amount of feed material for forward and backward movement of the dispenser over the area to be filled, which results in an equal amount of filling material reliably uniform filling of the area to be filled is ensured.

In a further preferred embodiment of the dispensing device, it is provided that above the conveyor belt, a grate for filtering and / or loosening up the backfill material is arranged. In addition to the measures already described above, which counteract lump formation of the filling material, the grate - in particular with an adaptable grid width as required - already contributes to de-filling the filling material and to its cleaning when filling the receptacle and / or the conveyor belt.

In a further preferred embodiment of the dispensing device according to the invention, it is provided that the distribution brushes are rotationally drivable, in particular oscillating about a vertical axis. By this driven movement thereby a particularly uniform distribution of the filling material and its particularly good incorporation into the surface to be filled is effected. Just one around the vertical axis

Oscillating movement of the distribution brush has been found to be particularly efficient.

In a further preferred embodiment of the dispensing device, provision is made for the erecting brushes to be rotatable, in particular oscillating about a transverse axis. This ensures a particularly good surface incorporation of the filling material into the fibers and consequently an even better distribution of the filling material over the surface to be filled. Just an oscillating movement of Aufrichtbürsten ensures that, for example, in all directions flat pressed fibers are reliably placed again, and the backfill material never comes to rest on the fibers themselves, but always between them. In a further preferred embodiment of the dispensing device, it is provided that the distribution brushes and / or Aufrichtbürsten are mounted vertically adjustable on the base frame. As a result, in particular a wide variety of artificial turf surfaces and / or filling materials and / or filling quantities can be processed or processed with one and the same dispensing device. As a result, such a dispenser can be used particularly flexibly, without experiencing limitations in terms of reliability and ease of handling.

In a further preferred embodiment of the dispensing device, it is provided that the base frame has at least one chassis for its movement over a surface to be filled. In principle, the base frame can indeed be designed as a moving part, for example on a vehicle. However, if it has its own landing gear, it can be moved in a particularly simple manner.

In a further preferred embodiment of the dispensing device, it is provided that the at least one chassis has its own drive. Of course, the dispensing device according to the invention can also be moved by hand, but with a corresponding self-propulsion, it is in any case particularly easy to use and in addition, particularly independent of the entrained weight of the backfill material particularly easy to use.

In a further preferred embodiment of the dispensing device, it is also provided that the base frame has a traction device and / or a mounting device, so that it can be pulled by a vehicle or transported on this. For a weight-reduced design of the dispensing device according to the invention is possible, which does not damage the surface to be filled even at high loading with filling material. In a further preferred embodiment of the dispensing device, it is additionally provided that the conveying direction of the conveyor belt is parallel or antiparallel to the direction of movement of the dispensing device. As a result, the backfilling material can either be fed to a desired delivery section of the conveyor belt when the delivery device is moving in the forward or reverse direction, thus ensuring uniform backfilling of the surface to be filled, even at the point of inflection of a treatment path over the length of the delivery device.

In a further preferred embodiment of the dispensing device, it is finally provided that the width of the conveyor belt corresponds to a track width of the chassis, but at least 50%, 70% or 90% of the track width of the chassis. This ensures a particularly efficient delivery of the filling material, since a particularly large surface can be filled over a processing path. In particular, however, a less frequent turning of the dispensing device at the edges of the surface to be filled is necessary, which makes it particularly easy to handle.

In view of the abovementioned advantages of the dispensing device, this is preferably to be used for filling artificial turf surfaces with sand and / or granules.

In the accompanying drawings, the invention is shown schematically in particular in two embodiments.

Fig. 1 is a longitudinal side cut

View of an embodiment of a dispensing device according to the invention, and Fig. 2 is a side view of a second embodiment of a dispensing device according to the invention.

In the figures, the same or corresponding elements are denoted by the same reference numerals and therefore, if not appropriate, will not be described again. 1 shows a longitudinal sectional side view of a first embodiment of filling material delivery device 10 according to the invention on a surface to be filled, in particular of synthetic grass surface sand, comprising a base frame 11 and a conveyor belt 20 guided thereon for feeding the filling material to two delivery sections 21, 21 'is equipped. The said discharge sections 21, 21 'are formed on a left or right guide roller 22, 22', where the backfill material depending on the direction of travel of the dispenser 10 either left or right freely down to the

to be filled area falls. In each case in the vicinity of the guide rollers 22, 22 'attached metering means 32, 32', which are formed in this embodiment as adjustable slide form with the conveyor belt 20 has a corresponding gap, which allows a volume control of the discharged filling material. The filling material, such as, for example, sand and / or granules, is supplied via a grid 42 to a funnel-shaped receiving container 40 and stored therein, whereby first clumps of the filling material possibly still wet by a washing process dissolve. The conveyor belt 20, the filling material is supplied via V-shaped adjoining baffles 41, 41 'in the respective selected transport direction.

If the dispensing device shown here, for example, by means of a traction device 51 on their trolleys 50, 50 'moves to the left, is the left discharge section 21 active, that is, the filling material slides along the guide plate 41 on the conveyor belt 20, where it is aligned flat. It then falls freely over the guide roller 22 down, where it comes to lie in the direction of travel in front of two successively arranged distribution brushes 30, 30 ', which distribute it in the sequence again over the area to be filled. The distribution brushes 30, 30 'thereby exert a rotating about a vertical axis, in particular oscillating rotational movement, which ensures a particularly efficient distribution of the backfill material. In total, this ensures a highly uniform distribution of the filling material which can be regulated in terms of height via the metering means 32, via the grate 42, the conveyor belt 20, the delivery section 21 and the distribution brushes 30, 30 ', as on the surface to be filled. This applies in no other way to a direction of travel of the dispenser 10 to the right, in which the discharge section 21 'is active, that is, the filling material on the guide plate 41' and the conveyor belt 20 a gap between the dosing means 32 '

and the conveyor belt 20 is fed, behind which it falls over the guide roller 22 'down. In this case, the conveyor belt 20 moves in the direction of travel of the dispenser 10 to the left in the counterclockwise direction and in the direction of travel of the dispenser 10 to the right in a clockwise direction.

For processing different surfaces to be filled, in particular artificial turf surfaces with different pile heights, filling materials and / or Verfüllmengen, the height of the Verteilbürsten 30, 30 'via a corresponding adjustment mechanism on the base frame 11 may be designed adjustable in height. In this embodiment, the energy supply for the guide rollers 22, 22 'and the distribution brushes 30, 30' should be carried out by a towing vehicle in order to save correspondingly heavy energy carriers on the delivery device 10 itself. As a result, the amount of entrained backfill material can be significantly increased, whereby in the chassis 50, 50 'is designed so that the highest possible maneuverability of this amount of backfill material in both directions is particularly easy.

Fig. 2 shows a side view of a second embodiment of the dispensing device 10 'according to the invention for filling material on a surface to be filled, which, in contrast to the embodiment described above the respective Verteilbürsten 30, 30' upstream Aufrichtebürsten 31, 31 'in the corresponding direction. These are driven about a transverse axis to the respective direction of travel of the dispensing device 10 'rotating, in particular oscillating. As a result, for example, a pile of an artificial turf is erected reliably before the filling material falls, for example, in the direction of travel of the dispensing device 10 to the left, via the dispensing section 21 onto the surface to be filled between the erecting brush 31 and the distribution brush 30. In a direction of travel of the dispenser 10 to the right is as already

described in the first embodiment of the invention, the discharge portion 21 'in which the filling material between the Aufrichtbürste 31' and the Verteilbürste 30 'comes to rest. Also, the Aufrichtbürste 31 'performs a corresponding rotationally driven, in particular oscillatory movement about a transverse axis to the direction of travel of the dispenser 10.

In a further difference from the first embodiment of a dispensing device 10 according to the invention, the embodiment of a dispensing device 10 'shown here also has a height adjustment device 33, via which the dispensing brushes 30, 30' and the erecting brushes 31, 31 'on the base frame 11' are vertically adjustable in order to be able to process or process different areas to be filled, filling materials and / or filling quantities. For the transport and feeding of the filling material to the conveyor belt 20, the dispenser 10 'in turn has an NEN funnel-shaped receptacle 40 in which this filling material is received. Also in this dispenser 10 'form the left and right sides of the funnel-shaped receptacle 40 attached dosing means 32, 32' together with the conveyor belt 20 has a corresponding gap, on the function of the sliders designed as dosing means 32, 32 'a desired discharge amount of the backfill material is adjustable , Otherwise, the dispenser 10 'shown here is also equipped with a chassis 50, 50' and a traction device 51, via which it is easy to maneuver in both directions.

In principle, however, both of the embodiments described above may also have their own drive and / or be equipped with a base frame 11, 11 ', which allows their attachment or their entrainment on a vehicle. However, with appropriate maneuverability requirements for the dispensers 10, 10 ', it may also be useful to make them manageable. In this case, a corresponding power supply for the operation of the guide rollers 22, 22 ', the Verteilbürsten 30, 30' and / or Aufrichtbürsten 31, 31 'may be provided or these -. for smaller dispensers - be mechanically coupled to a chassis of the dispenser.
