    The invention relates to a discharge device for granules, comprising a housing with at least one inlet opening for the granulate, with a motor connected to a motor, a rotary axis, a multi-vane feeder and interposed chambers in which chambers the granules upon rotation of the cell wheel from the at least one inlet opening to at least one outlet is conveyable.
    By the term " granules " is a granular to pulverförmi¬ger, easily pourable solid to understand, for example, scattered or debris sand, as it is used to improve the Bremswir¬kung between the wheels of vehicles and the roadway. For example, in rail vehicles Granulatbzw. Sand from a container via a metering and conveying device via a nozzle in front of the rail wheels in the gap between the rail wheel and rail promoted to increase the frictional resistance between rail wheel and rail and to reduce the braking distance.
    For example, AT 505 783 Bl describes such a scattering device, wherein the metering of the spreading material is carried out via a rotating cell wheel.
    Another spreader, in which the metering and conveying of the feedstock takes place with compressed air, has become known, for example, from WO2008 / 064747 A1.
    Particularly when using relatively hard granules, for example quartz sand, there is the problem of a relatively rapid wear of components of the discharge device, the granulate or the sand due to the friction on the components of the discharge device to a rapid deterioration of the discharge function or even to a Malfunction leads. By using very high quality and durable materials for the components of the discharge device, no significant improvements could be achieved, as it can cause blockage when the hard granules meet moving parts of the discharge device also of hard material. Better results could therefore be achieved by using softer, but also less resistant materials, in particular for the moving parts of the discharge device. For example, cellular wheels are often made of plastic, which, however, significantly reduces service life. However, the replacement of wearing parts causes service life and assembly costs, which are usually undesirable. Especially with spreaders, such as are commonly used in rail vehicles, low downtimes and short maintenance intervals are not desirable.
    The object of the present invention is therefore to provide an above-mentioned granular discharge device, which is characterized by a low wear, an increased service life and thus extended maintenance intervals. The disadvantages of existing discharge devices with regard to the wear are to be reduced or prevented.
    The object of the invention is achieved in that the Dreh¬ axis of the cell wheel is arranged vertically. Alone by the vertical arrangement of the axis of rotation of the cell wheel, the wear properties can be improved because the granules by gravity trickles substantially into the cells of the cell wheel and is conveyed upon rotation of the cell wheel to the at least one outlet. In addition, a cellular wheel having a vertical axis of rotation can be more easily assembled and disassembled, so that maintenance time and also maintenance costs can be reduced.
    Advantageously, the cell wheel is arranged within a substantially cylindrical wear bushing. The wear bushing, which may be formed of suitable material, is easily and quickly replaceable without having to replace the entire discharge device. Due to the substantially vertical arrangement of the wear bush, removal and installation from the underside of the discharge device is possible in a simple and rapid manner.
    If the at least one outlet is arranged on the underside of the wear bush and is preferably slot-shaped, particularly advantageous paths of the granulate from the container of the granulate to the at least one result
    Outlet and thus to a relatively short residence time of the granules within the discharge or the Zellenra¬des, which in turn leads to low wear. After at least one outlet, the granules may be conveyed in different ways to the desired destination, for example by mechanical or pneumatic conveyance.
    Ideally, the bucket has at least eight wings. As a result, there are at least eight chambers between the blades of the cellular wheel within which the granulate is conveyed. The more blades or intervening chambers the cell wheel has, the lower is substantially the residence time of the granules within the cellular wheel and thus the wear of the cellular wheel or the Cell wheel surrounding Verschlei߬ bushing.
    If the blades of the cell wheel are formed like a blade, a further optimization of the transport of the granules mit¬ help of the cellular wheel can take place to the at least one outlet and the friction of the granules are re¬duziert to the wings of the cell wheel.
    The housing of the discharge devices is preferably designed for arrangement within a container for the granules, and the at least one inlet opening is arranged laterally on the housing. By such a construction, on the one hand, the construction height of the granule container and the discharge device as well as any conveyor can be kept low and the maintenance can be facilitated since the discharge device can be dismounted from below from the granulate container and mounted again. The arrangement of the discharge in Granulatbe¬ hälter optimal protection against external influences is achieved and thus unwanted Störpoten¬ziale and thus system failures are effectively avoided. In addition, gravity is optimally exploited by allowing the granules to trickle without help from the container into the at least one inlet opening. From the feed openings arranged laterally on the housing, the granules pass directly into the chambers between the blades of the cell wheel and are transported when the cell wheel rotates and then reach the at least one correspondingly arranged outlet for further transport of the granules.
    Advantageously, two opposite inlet openings are provided on the housing. As a result, the conveyed amount of granulate can be increased at a constant rotational speed of the cell wheel or the rotational speed of the cell wheel can be correspondingly reduced with the same amount of granulate conveyed. In addition, with two or more inlet openings, the paths of the granules within the discharge device between inlet opening and outlet can be reduced and thus the wear can also be reduced.
    Optimal trickle or flow conditions for the granules are then given if the inlet openings are arranged diagonally downwards, preferably at an angle of 30 to 40 ° to the horizontal. It is advantageous if the underside of the granulate container is already arranged obliquely in a similar manner and merges into the corresponding obliquely arranged inlet openings of the discharge devices.
    If the motor is arranged above the cellular wheel, the assembly and disassembly of wearing parts of the discharge device can be facilitated.
    On the underside of the housing fastening elements for fastening a device for conveying the granules are provided, which conveying device can be designed in various ways. Depending on the application, mechanical or pneumatic conveyors are mainly used.
    It is also advantageous if the wear bush is displaceable relative to the cellular wheel in the direction of the axis of rotation of the cellular wheel. As a result, a compensation of the wear or a readjustment of the discharge device can be achieved and the service life can be increased and the maintenance intervals extended.
    This readjustment can be effected, for example, by the wear bush being displaceably mounted in the direction of the Zel¬lenrad via at least one spring. By means of the spring-supported displaceable mounting of the wear bushing, abrasion on the wear bushing and / or the cellular wheel can be compensated to a certain degree and thus the service life of the discharge device can be extended.
    Alternatively, the cellular wheel can be mounted ver¬schieblich together with the motor via at least one spring in the direction of the wear bushing. The at least one spring thus presses the cellular wheel against the wear bushing and thus compensates for wear to some extent.
    According to a further feature of the invention, the vanes of the cellular wheel are arranged obliquely on the underside in the direction of the rotational axis of the Zel¬lenrades, and formed the underside of the wear bushing complementary to the wings of the cell wheel funnels. As a result, the delivery of granules within the discharge device is even further assisted and the wear due to friction of the granules on the components of the discharge device is reduced.
    Advantageously, the cellular wheel made of plastic, vorzugswei¬se polyurethane. Plastic is relatively cheap and has good corrosion resistance. Ultrahigh molecular weight polyethylene has particularly good wear properties. Theoretically, metallic materials are also conceivable for the cellular wheel and the wear bushing. However, one of the two components should be resilient to the other component and therefore preferably formed by plastic.
    The wear bushing may also be formed of plastic, preferably ultra-high molecular weight polyethylene.
    The invention will be explained in more detail with reference to the accompanying drawings. Show:
    1 shows a variant of a discharge device in horizontally cutaway view;
    FIG. 2 shows the discharge device according to FIG. 1 along the section line II-II; FIG.
    3 shows a further variant of a discharge device in a hori¬ zontal cut view.
    FIG. 4 shows the discharge device according to FIG. 3 along the section line IV-IV; FIG. and
    Fig. 5 is a schematic block diagram of a use of the discharge device in a sand dispenser.
    Fig. 1 shows a variant of a discharge device 1 in hori¬zontal cut view. The discharge device 1 is preferably arranged within a container 12 for the granules 2. By a vertical installation position of the Austragseinrich¬ 1 in the container 12 for the granules 2 an optimal protection of the discharge device 1 is achieved against external influences in a simple manner and thus unwanted interference potentials and thus system failures are effectively avoided. The discharge device 1 comprises a housing 3 with at least one inlet opening 4 for the granules 2 and a cellular wheel 6, which is connected to a motor 11. The cellular wheel 6 has a plurality of vanes 7 and chambers 9 arranged there between, in which the pellets 2 are conveyed from the at least one inflow opening 4 to at least one outlet 5 during rotation of the cellular wheel 6. The wings 7 and 9 chambers of the cellular wheel 6 are shown in the sectional drawing according to FIG. 2 better visible. According to the invention, the axis of rotation 8 of the cellular wheel 6 is arranged substantially vertically, so that the granules 2 can be fed into the chambers 9 of the cellular wheel 6 via the feed opening 4 and conveyed to the at least one outlet 5 when the cellular wheel 6 is rotated becomes. As a result of the arrangement according to the invention, the paths of the granulate 2 within the discharge device 1 are short and the residence time of the granules 2 in the discharge device 1 is short, as a result of which the wear, in particular of the cellular wheel 6, can be kept low. Ideally, the bucket 6 is disposed within a substantially cylindrical wear bushing 10. The wear bush 10 and the cellular wheel 6 are characterized in the subject construction by a long service life and long maintenance intervals. Should they still need to be replaced, they are simply exchangeable from the bottom of the container 12 for the granules 2. Advantageously, the feeder 6 has at least eight wings 7 and thus eight chambers 9. The ZulaufÖffnungen4 are preferably arranged laterally on the housing 3 of the discharge 1 and arranged as the bottom of the container 12 for the granules 2 inclined. The at least one outlet 5 of the discharge device 1 is preferably arranged on the underside of the wear bushing 10 and is preferably slot-shaped, as can be seen from FIG. As a result of the abrasion of the granules 2 on the cellular wheel 6 or its wings 7 and the wear bushing 10, abrasion occurs which, to a certain extent, leads to the fact that no optimum transport or dosing of the granulate 2 can take place. In order to prevent the wearing parts of the discharge devices 1 having to be changed frequently, the wear bushing 10 according to the invention is designed to be displaceable relative to the cellular wheel 6 in the direction of the axis of rotation 8 of the cell wheel 6. This is done in the Aus¬führungsvariante according to FIGS. 1 and 2 by at least one spring 15, which presses the wear bush 10 in the direction of feeder 6. In this way, a readjustment of the Verschlei߬ bushing 10 relative to the feeder 6 to a certain extent, for example, a few millimeters, take place and thus increases the service life of the discharge device 1 and the maintenance intervals are extended.
    The cellular wheel 6 is preferably made of plastic, preferably polyurethane, whereas the wear bushing 10 may also be made of plastic, preferably of ultra-high molecular weight polyethylene. The housing 3 of the discharge device 1 is preferably made of corrosion-resistant, lightweight metal, for example aluminum or an aluminum alloy. The motor 11 for driving the cellular wheel 6, which is preferably arranged above the cellular wheel 6 in order to facilitate the assembly and disassembly of the cellular wheel 6, may be formed by a DC geared motor.
    FIG. 3 and FIG. 4 show a further variant of a discharge device 1 in a horizontally sectioned view, with a wear tracking modified in comparison with the variant according to FIGS. 1 and 2. In this embodiment variant, the wear bush 10 is not biased in the direction of the cellular wheel 6, but the cellular wheel 6 is pressed together with the motor 11 via at least one spring 15 against the wear bushing 10. Also in this way, a readjustment or a Verschleißkompen¬sation take place. Otherwise, the components are essentially identical to those shown in FIGS. 1 and 2. Due to the displacement of the motor 11 and the Zellenra¬des 6 relative to the wear bushing 10, the fastening elements for mounting the motor inside the housing 3 must be arranged in corresponding oblong holes, which allow a shift in the direction of the axis of rotation 8 by a few millimeters.
    Finally, FIG. 5 shows a schematic block diagram of a use of the discharge device 1 in a sand-spreading device. The discharge device 1 is arranged in the container 12 for the granules 2 and connected to a corresponding control device 16. The control device 16 controls the rotational speed of the cellular wheel 6 in the discharge device 1 and thus the amount of granules, as it is forwarded to the conveyor 14, which is arranged below the discharge device. In the example shown, the conveying device 14 for conveying the granulate 2 is formed by a pneumatic conveying device. For this purpose, compressed air is introduced from a compressed air source 17 via a Druckluftlei¬ tion 18 in the conveyor 14 and the Granu¬lat, which trickles down from the discharge 1 via the at least one outlet 5, via a conveyor line 19 also desired location, for example in front of the rail wheel of a rail vehicle.
    Other variants of the control of the discharge device 1 and promotion of the granules 2 are of course also conceivable.
    The present invention is characterized by optimum wear properties without the construction of the discharge device being particularly complicated or expensive.
