    The invention relates to a cleaning device for a pallet mold for the production of prefabricated concrete components, comprising at least one scraping element, with the pollution objects of the surface to be cleaned of the pallet shape are schabbar and at least one brush.
    In particular, in the production of precast concrete components in pallet circulation systems, a high degree of production efficiency and high demands on the quality of the manufactured precast concrete components is required. A trained in the form of a production line pallet circulation system includes here mostly a Abhebestation for the cured precast concrete components and a demolition for removing the formwork and a cleaning station for cleaning the pallet form on which the precast concrete component is made, and optionally the formwork and the cured precast concrete component. Subsequently, in principle, a new production cycle for a further precast concrete component can be started with the pallet form.
    In this case remain after lifting the hardened precast concrete components and removing the formwork on the pallet form pollution objects of various types. To ensure the quality of the next concrete precast component to be manufactured, the pallet form must be cleaned before a new occupancy with formwork elements and the subsequent manufacturing process of precast concrete component of the objects of pollution. This is usually done by a cleaning device, the cleaning station mentioned above
    Pallet circulation system is assigned.
    In this case, cleaning devices of the prior art comprise one or more cleaning agents, which lead to a cleaning of the same by a relative movement between the cleaning agent and the pallet shape. If the cleaning device is basically stationary, the pallet shape moves "under" the cleaning device and is cleaned in a continuous process. On the other hand, there are movably mounted cleaning devices or cleaning devices with movably mounted cleaning agents, wherein the cleaning devices or the cleaning agents move relative to the stationary pallet mold and thereby perform the cleaning. The cleaning device and / or the cleaning agent can be moved in different directions of movement over the pallet shape. 68712 35 / hn
    A scraping member serves to remove solid debris such as e.g. Concrete residues, Styrofoam pieces, remnants of wood formwork, etc. In particular, not removed from the scraper or incurred by the scraping finer pollution objects are removed by a brush, for example, rotates about a substantially parallel to the surface to be cleaned arranged axis. This brush can extend over the entire pallet shape and thus serve to clean the entire pallet shape. Usually, the pallet shape is arranged horizontally, so that the brush rotates in this case in the operating state about a horizontal axis.
    Additionally or alternatively, the cleaning device may comprise further variously formed brushes, such as e.g. at least one disc brush rotating about an axis perpendicular to the surface to be cleaned, e.g. Dries dried Betonmilchreste from the pallet form or from the shell elements. Laterally arranged mold brushes are used to clean the fixed or hinged side molds.
    To produce the precast concrete components, it is necessary to oil areas of the formwork and the pallet mold, in order subsequently to separate the hardened precast concrete component from the formwork or the pallet form and to protect it from corrosion. The oiled surfaces with form oil pose a problem for the cleaning, as the rotating brush is contaminated by the contact of the oiled surfaces with the finer dirt particles described above and therefore on the pallet shapes that should be cleaned, despite cleaning oil residues in the longitudinal direction of the rotating Brush remain. These traces of oil are becoming increasingly strong as the number of manufacturing cycles increases, since the degree of contamination of the rotating brush increases.
    Moreover, with a cleaning device as described above, it is difficult to remove the imprints left in the residual oil caused by the holding magnets which hold the formwork on the pallet form.
    Such contaminated pallet shapes or formwork are particularly a problem when a smooth fair-faced concrete prefabricated component is produced in a next manufacturing cycle, after stripping this exposed concrete prefabricated according to the contaminants more or less well-trained strokes or impressions of dirt by the magnets due to improper cleaned pallet form are recognizable.
    In order to avoid these contaminants of prefabricated concrete prefabricated components, it may be provided to manually clean the pallet forms and optionally also the formworks after the cleaning process by the cleaning device, wherein the contaminated oil film is removed and a renewed oiling of the formwork and the pallet shape is necessary. This manual activity is associated with a high workload.
    Moreover, in the case of manual cleaning, there may be no formwork oil among the formwork elements arranged in various shapes on the pallet mold, so that the pallet mold can oxidize in these areas, especially if the pallet mold is left in the drying chamber for a longer time, for example during a weekend remains. This oxidation also pollutes the pallet shape. Such contaminants are again visible on the manufactured precast concrete components.
    The object of the invention is therefore to provide a cleaning device with which the above-mentioned disadvantages can be avoided and a fast and efficient cleaning of pallet shapes and possibly also of formwork elements in pallet shapes is made possible.
    This is achieved by a cleaning device having the features of claim 1.
    With the cleaning device according to the invention, a surface of a pallet mold to be cleaned can be cleaned for the production of precast concrete components. In addition, the formwork or formwork elements can be cleaned with the cleaning device. For this purpose, it may be provided to fold the formwork elements in a plane parallel to the surface to be cleaned of the pallet form.
    At least one scraping element serves to scrape off soiling articles from the surface of the pallet mold to be cleaned. One or more, preferably parallel, scraping elements may be provided. The scraper elements can also be lowered to the surface to be cleaned by means of a pivoting movement and / or a vertical movement on the surface to be cleaned and lifted away from it. The scraping takes place by means of a relative movement of the pallet mold and the cleaning device, in particular of the scraping element of the cleaning device.
    A rotating in the operating state brush, serves to further clean the surface of dirt, the cleaning surface of the brush according to the circumstances, i. depending on the surface to be cleaned and the objects of contamination, may be selected and, for example, has bristles.
    According to the invention, a feeding device is provided between the scraping element and the brush, from which a pourable and absorbent good can be fed to the surface to be cleaned. The pourable and absorbent good are e.g. Wood shavings or special plastic granules. It may be provided in each cleaning process optionally depending on the size of the surface to be cleaned to use a certain amount of pourable and absorbent Good. The pourable and absorbent material absorbs the excess oil on the surface to be cleaned. By the rotating brush, the absorbent and pourable material is triturated on the surface to be cleaned and thus dissolves stubborn dirt.
    Further advantageous embodiments of the invention are defined in the dependent claims.
    In a first embodiment of the invention, the brush rotates in the operating state about an axis arranged substantially parallel to the surface to be cleaned. If the pallet shape is arranged horizontally, the brush is rotatable about a horizontal axis and is therefore also called a horizontal brush. The brush can occupy the entire length or width of the pallet shape, so that by a relative movement between the brush and pallet shape by the brush is moved relative to the pallet shape transverse or longitudinal, the entire pallet and optionally also folded shuttering elements can be cleaned.
    In a second embodiment of the invention, the brush is rotatable about an axis arranged substantially perpendicular to the surface to be cleaned and, for example, designed as a disc brush. Such a brush has a cleaning surface, which is provided with a suitable cleaning agent such as bristles or a felt layer and has the advantage that during rotation, a high pressure on the surface to be cleaned can be exercised, whereby a particularly good cleaning can be realized. In addition, such brushes have the advantage that a large area of the surface to be cleaned is cleaned at the same time. This is especially true for circular "* * 5
    Cleaning surfaces too. In operation, this brush generally rotates about a vertical axis, so the brush is also called a vertical brush.
    In one embodiment of the invention, the supply device has a distributor, with which the pourable and absorbent material can be distributed on the surface to be cleaned at least over a certain range, so as uniform as possible cleaning a majority of the surface to be cleaned by means of the pouring and absorbent material is possible. The distribution device can be characterized by a special geometric design of the feeder or by other mechanical aids, such. a movable storage of the feeder can be realized. But it can also be provided that the distribution of the pourable and absorbent Guts by pouring the Guts from the feeder to the surface to be cleaned automatically.
    In a particularly preferred embodiment of the invention, the cleaning device has a first brush and a second brush, wherein the first brush is rotatable about an axis arranged substantially perpendicular to the surface to be cleaned, and wherein the second brush about a substantially parallel to be cleaned Surface arranged axis is rotatable. This allows the advantages of both types of brushes above to be combined. In particular, it is possible to arrange differently coarse cleaning agents on the first and the second brush, so that a coarse and a fine cleaning are possible.
    In a particularly preferred embodiment of the invention, the first brush, which rotates in the operating state about a substantially perpendicular to the surface to be cleaned between the second brush, which is rotatable about an axis arranged substantially parallel to the surface to be cleaned and arranged the feeder. In this case, the first brush has a cleaning surface, with which the surface to be cleaned can be treated. The brush rotating in the operating state about an axis arranged substantially perpendicularly to the surface to be cleaned can have, for example, a circular rotating metal disk from which a surface to be arranged on the surface to be cleaned is specially designed as a cleaning surface. The cleaning surface may be provided with optionally fine bristles or a polishing agent.
    From the rotating cleaning surface, the pourable and absorbent material is pressed onto the surface to be cleaned and removed by the rotation of the first brush * 4

    Dirt on the surface to be cleaned. A circular cleaning surface has the particular advantage that the largest possible area of the surface to be cleaned can be cleaned at the same time, while the brush rotating about an axis arranged substantially parallel to the surface to be cleaned essentially has only one line-shaped support.
    In principle, it can also be provided that instead of the brush arranged to rotate about an axis perpendicular to the surface to be cleaned, at least one brush which can be moved back and forth along the surface to be cleaned is provided, wherein the trituration of the pourable and absorbent material on the surface to be cleaned instead of being realized by a rotational movement of the brush by a small-scale back and forth movement.
    Both the rotational movement and the reciprocating motion are made by a known drive unit with a motor. In addition, it can be provided that the brush is movable relative to the surface to be cleaned, so that with the brush or brush (s) as large a portion of the surface to be cleaned can be cleaned.
    Depending on the design of the cleaning surface serving in the operating state about a substantially perpendicular to the surface to be cleaned axis rotating brush serves as a fine cleaning and can be used as a polishing, wherein in one embodiment of the invention, the cleaning surface is formed as a felt layer with which the surface to be cleaned is treatable. The felt layer can be connected to the brush in a simple manner, so that a replacement of the felt layer is possible without problems.
    In a further embodiment of the invention, the brush in the operating state about an axis arranged substantially perpendicular to the surface to be cleaned rotating brush and additionally or alternatively the at least one scraper element by means of a pivoting movement and / or a vertical movement on the surface to be cleaned can be arranged. An opposite movement causes a lifting of the brush or the scraping element from the surface.
    If the pourable and absorbent material is in the region of the brush (s), these can be lowered onto the surface to be cleaned and rub the pourable and absorbent good by a pressing and a rotary or small-scale reciprocating movements and thus the fine cleaning enable.
    In a further embodiment of the invention, a dirt container is provided which can be arranged in the region of the brush which rotates about an axis arranged substantially parallel to the surface to be cleaned and can be picked up by the contaminants which are removed from the surface by the brush, for example due to their rotation , In addition, from this brush and on the surface to be cleaned remaining pourable and absorbent good, such as the wood chips removed and can also be transported in the dirt container. The dirt container can empty automatically after each cleaning cycle.
    In a further embodiment of the invention, the cleaning device has at least one brush, which rotates in the operating state about an axis arranged substantially perpendicular to the surface to be cleaned axis, wherein the brush may be formed as a disc brush and having the advantages mentioned above. The removal of the remaining on the surface pourable and Gutsgut together with the objects of pollution can be done instead of means of a parallel to the surface to be cleaned rotating axis brush with a suction device, which the pollution objects and the pourable and absorbent good of the now cleaned Siphoned surface and transferred to a dirt container. The brush is arranged in this case between the scraper and the suction device. However, such a suction device can also be provided in addition to the brush arranged around an axis arranged substantially parallel to the surface to be cleaned.
    The cleaning device may further comprise a pre-brush, which is used on the surface to be cleaned in front of the scraper element and coarser objects of contamination to thereby protect the scraper element.
    The invention further relates to a pallet circulation system for the production of prefabricated concrete components, in which the preparation of precast concrete components takes place on pallet forms, said pallet circulating system having a cleaning station with a cleaning device as described above. A pallet circulation system in which precast concrete components are produced as pallet forms in a production line is described, for example, in the Austrian patent application AT 506 748 A1. In addition to a cleaning station are doing u. a. a formwork station, a concreteing station, an end scarf station and a movement station and a hardening and / or drying chamber and a lifting station are part of the pallet circulating system.
    Preferably, it is provided that the cleaning station is automated, especially since several of the remaining stations are automated executable, whereby the efficiency of the production of precast concrete components is further increased.
    The invention further relates to a method for cleaning a pallet mold for the production of prefabricated concrete components with a cleaning device as described above. In this case, there is a relative movement between the cleaning device and the surface to be cleaned, so that the surface to be cleaned is first treated by the scraping element by scraping coarser dirt particles. Subsequently, by the feeding device which rotates between the scraper element and the second brush which rotates about an axis arranged substantially parallel to the surface to be cleaned, the pourable and absorbent material is supplied to the surface to be cleaned and optionally with the distributor device on the distributed to be cleaned surface. However, it can also be provided that the distribution is effected automatically by the feeding, for example by a bulk process. By moving the arranged on the surface to be cleaned arranged pourable and absorbent Guts by means of the brush, the cleaning of the surface to be cleaned. Finally, the accumulated objects of pollution and remaining on the surface remains of the pourable and absorbent Guts example, removed with a suction device, so that the surface to be cleaned is now cleaned and is available in a clean and dry state with no troublesome traces of oil for another manufacturing cycle.
    In a particularly preferred embodiment, the cleaning comprises two partial steps, namely a first cleaning with the first brush, which is arranged between the second brush and the feeding device, wherein by the rotation of the first brush a movement or, trituration of arranged on the surface to be cleaned pourable and absorbent Guts takes place. By means of the second brush rotating in the operating state about an axis arranged substantially parallel to the surface to be cleaned, a second cleaning and possibly removal of the accumulated objects of soiling and the residues of the pourable and absorbent material remaining on the surface takes place. • t ·· I «*» * * ί * * # * 9 t * i * i * »* a · * * · I tr # * * * 9 l ·« * «« 9 * * »* · # 9 «« · * · «* · 9

    Fig. 2 is a cross-sectional view of a cleaning device according to the invention and
    3a and 3b is a side view and a perspective view of a
    Feeder.
    1a shows a perspective view of a cleaning station 13 of a pallet circulation system, wherein a cleaning device 1 is arranged in the cleaning station 13 with which the surface 3 of the pallet molds 2 to be cleaned is cleaned. For this purpose, the individual pallet shapes 2, 2 ', 2 "are moved by the cleaning station 13 by means of a transport device 16 after the shuttering and lifting of hardened precast concrete components along the pipe direction A. The surface 3 is cleaned after passing through the cleaning station 13, while the surface 3 is dirty before passing with dirt objects 11, in particular an oil film due to the production of precast concrete components. In particular, the pallet mold 2 'has an already completely cleaned surface 3', while the surface 3 "to be cleaned of the pallet mold 2 " is still completely dirty.
    Fig. 1b shows the cleaning station 13 in an enlarged view. When passing the pallet form 2 in Pfeiirichtung A coarser objects 11 are first removed with a pre-brush 12. As a further consequence, a scraping element 4 serves to scrape off further objects of contamination 11. Both the brush 12 and the scraping element 4 can be lifted off the surface 3 to be cleaned by means of a lever mechanism 15 known per se. At the top of the cleaning device 1, a hopper 14 is arranged, in which the pourable and absorbent material can be filled.

A provided with rollers transport device 16 is used for further transport of the pallet 2 in the direction A, the feeder 6 has below
    10 of the hopper 14 to a reservoir 17 for the pourable and absorbent good, which opens into a rotary valve 18, which pours the good on the surface 3 to be cleaned. Subsequently, a first brush 9 is arranged, which is provided with a rotating circular cleaning surface 20. The rotation is made possible by a drive 19, wherein the drive 19 and the cleaning surface 20 connected to the drive 19 can be pivoted away from the surface 3 to be cleaned by means of a further lever mechanism 21. For cleaning, the cleaning surface 20 is pressed onto the surface to be cleaned 3 and rubbed by the rotation of the sucking and pourable Good, which on the one hand absorbed the oil film and on the other hand finer dirt objects 11 are removed. The cleaning surface 20 is formed for example by a felt layer, which is arranged on a plate consisting of a metal.
    As a consequence, a second brush 5 rotating about an axis 22 to be cleaned parallel to the axis 22 serves for further cleaning, as a result of the rotation objects 11 and the material remaining on the pallet mold 2 are conveyed into the collecting container serving as a dirt container 10. The rotation of the second brush 5 is also carried out by a known drive.
    Fig. 3a shows the feeder 6 with the reservoir 17 and the hopper 14 in a side view. A guard 23 serves to keep unfit bodies from the feeder 6 for cleaning. The rotary valve 18 has a cellular wheel 24, which serves to supply the material into the outlet channel 25 and subsequently to the surface 3 to be cleaned. The lower part 26 is fixed by means of a lock 27 on the reservoir 17, wherein a pivoting of the lower part 26 about an axis of rotation 31 in unlocked state is possible. Between reservoir 17 and lower part 26, a seal 28 is arranged. By means of a feed channel 29 and a tear-off edge 30, the material is guided to the cell wheel 24.
    The defined spoiler edge 30, in conjunction with the circumferential recesses 34 on the outside of the cellular wheel 24 ensures that in the medium and long-term operation no blockages or jamming between the reservoir 17 and the rotary valve 18 can form. 11
