    Roller assembly comprising a scraper
    The invention relates to a roller assembly for forming a flat rolled, continuously conveyed dough sheet, comprising at least one rotatably mounted roller, a counter body, wherein between the roller and the counter body, a nip for supplying and Auswalzung of the dough strip is provided, a scraper, a plate-shaped strip body comprises, which is clamped on one side and is biased on the opposite side with its scraper edge biased to the roller. In particular, the invention also relates to a scraper of the type mentioned above for use in a roller assembly. Furthermore, the invention relates to a scraper for a roller assembly.
    Roller assemblies with scrapers have long been known and published in different embodiments.
    For example, pairs of rolls are known in which an endless dough sheet is diluted and thus rolled. For example, dough residues 2/15 «· · ··· · · · · · · · · · · · · · · · · · · · ····································································· To wipe off the dough strip adhering to the roll, scrapers corresponding to the prior art are used. These are usually designed as sheet metal plates, which are biased pressed against the roller.
    For example, roll arrangements are known in which sheet metal plates with a thickness of about 0.5 mm are pressed against the roll. Due to the elastic bias of the plate-shaped Abstreifplättchens the scraper over the entire width of the roller with constant pressure. Due to the elastic bias against the roller small tolerance differences can be compensated. Disadvantage of this design is that thin platelets are removed relatively quickly due to wear due to the constant friction between the roller and scraper. As a result, the plate loses the system to the roller and the functionality is greatly impaired. To change the scraper, the entire system for making the dough sheet and subsequently the entire baking system must be stopped.
    To prevent the rapid wear of the scraper scrapers are used with greater thickness according to the prior art. For example, metal scrapers are used with thicknesses of about 5mm. These are chamfered on the contact surface with the roller, so that a flat support and a sharp wiper edge are formed. A disadvantage of this design is that due to the relatively large thickness and the area moment of inertia and thus the flexural rigidity of the stripper are greatly increased. A resilient bias against the roller is thereby enabled only when high pressure and high forces. The high pressure between the roller and the scraper in turn results in increased wear and thereby unwanted removal of material of the scraper.
    Thus, with roller assemblies with scrapers, there is a trade-off between, on the one hand, the elastic tension of the scraper against the roller and, on the other hand, the thickness for increasing the contact surface and for reducing wear / tear.
    The object of the invention is to solve this conflict of goals. 3.15
    52059 GP / GA
    The object of the invention is achieved in particular by the features of the independent claim.
    In particular, in that the stripping body has a bending area and that the cross-sectional area of the stripping body is smaller in the bending area than in the area of the stripping edge, that the area moment of inertia of the stripping body is smaller in the bending area than in the area of the stripping edge that the cross-sectional area of the stripping body is smaller in the bending area is than outside the bending region and / or that the area moment of inertia of the stripper body in the bending region is smaller than outside the bending region.
    Further advantageous features of the invention are that the stripping body rests without interruption in a planar or linear manner over the entire width arranged for processing the dough strip on the roller, that in the bending region at least one recess is provided, that the stripping body is designed as a plate with a substantially constant thickness, in that the stripping body has at least one recess in the bending area, by which the cross-sectional area and the area moment of inertia in the bending area are reduced, and / or that the bending area runs essentially parallel to the stripping edge and is preferably oblong.
    Furthermore, it can be provided that in the bending area a plurality of recesses are provided that the recesses are designed as the plate-shaped stripper piercing through holes, that the stripper body is clamped along a line parallel to the stripping edge in a jig that the bending area between the jig and the wiper edge is provided and is preferably provided in the central region between the clamping device and the wiper edge and / or that the counter-body is designed as counter-rotating counter-roller, wherein on the counter-roller a scraper is provided according to the foregoing description.
    In order to solve the conflict of objectives mentioned above, the scraper according to the invention has a bending region in which the cross-sectional area and / or the 4/15 t ". * · ≫ · * · · ·

    Area of inertia is reduced / are. Thus, the scraper may be formed of a relatively thick plate, which is affected only slightly by abrasion wear. By reducing the area moment of inertia or the cross-sectional area, an advantageous elastic deformability or bending elasticity similar to a very thin stripping body is given.
    The shape as a substantially plate-shaped stripper body with recesses to reduce the cross-sectional area and / or the area moment of inertia is also a very efficient and therefore inexpensive construction.
    The device according to the invention comprises a rotatably mounted roller, which is positioned at a certain distance from a counter body. Between these two elements, a nip is provided for the passage of the dough strip. Optionally, in all embodiments, individual, separated from each other essentially pliable moldings can be performed. Examples are punched cookie dough shaped bodies for the formation of biscuits.
    The roller is driven in particular rotationally about an axis of rotation. Substantially parallel to this axis of rotation of the stripper body of the scraper on a scraping edge, which bears against the roller. However, according to a further embodiment of the invention, the stripping body can also rest obliquely on the roller, so that the stripping edge and the axis of rotation of the roller essentially run askew to each other.
    For holding the stripper body of the scraper, a clamping device is provided. This is for example designed as a jaw device, is clamped in between two plates of the scraper. In a preferred manner, the clamping is carried out along a line contact or surface contact running parallel to the wiping edge.
    The stripper body is preferably made of a plate-shaped body having a thickness of 0.5 mm to 1 mm. The stripping body is preferably made of a metal, in particular steel, in particular also stainless steel or spring steel. Through the 5/15 • · · · · · · · · · · #

    52059 GP / GA according to the invention reduction of the bending stiffness is given an optimal system of the stripper even at low contact pressure. As a result, the wear is reduced.
    The device according to the invention is suitable and / or adapted to be used "in-line" in an industrial production plant for food products.
    In a further consequence, the invention will be further described with reference to the figures.
    Fig. 1 shows a schematic side view of an embodiment of a construction according to the invention, wherein one of the side shields is hidden. Fig. 2 shows a detail of the scraper of the device according to the invention.
    Fig. 3 shows a schematic perspective view of the scraper of the device according to the invention.
    Fig. 1 shows an embodiment of a device according to the invention. This comprises a roller 2, a counterbody 3 and a roller gap 4 provided between the roller 2 and the counterbody 3.
    Through the nip 4, a dough sheet 1 is guided. In the schematic representation of the nip is shown wider than it is necessary for Auswalzung of the dough strip shown schematically. As a rule, the width of the gap, that is to say the distance between the two rolls, essentially corresponds to the thickness of the leaking dough bath.
    In the present embodiment, the counter body 3 is designed as a counter-roller 13. However, if necessary, this counter-body can also be designed as a conveyor belt, conveying surface or similar construction.
    The roller 2 and the counter body 3 are preferably driven so that the dough sheet is conveyed through the nip. For example, in the present illustration of FIG. 1, a movement of the dough sheet 1 from the left to the right is made possible by the drives of the two rollers. 6/15 ·· ··· · «· · · ·················································

    When commissioning of roller assemblies, it happens that the inserted front end of the dough sheet 1 adheres to a roll and is wound by this. To prevent this, a scraper 5 is provided. Also adhering dough residues are released by the scraper 5 of the roller. The scraper 5 comprises a substantially plate-shaped scraper body 6, which rests with its scraper edge 7 on the roller 2. Furthermore, the scraper 5 comprises a clamping device 12, which on the one hand serves to hold the stripping body 6 and on the other hand to bias the stripping body 6 biased to the roller 2. For this purpose, the clamping device 12 may comprise a rotatable or pivotable component which can be locked in a rotational position to press the stripping body in this position to the roller.
    The roller 2 and optionally the counter-roller 13 each have an axis of rotation 14. This axis of rotation 14 extends in the present representation substantially projecting.
    2 shows a detailed view of the scraper 5 and the roller 2. The scraper 5 comprises a clamping device 12, a stripping body 6 and a scraper edge 7, which is applied to the roller 2. The stripper body 6 is supported by the chuck 12 in the present embodiment. For this purpose, the clamping device 12 is connected to the machine frame of the roller assembly. Furthermore, the stripping body 6 is pressed via the clamping device 12 to the roller 2. The opposing forces or moments are supported on the machine frame via the clamping device 12. The clamping on the Einspannvorrichtgung takes place in the present embodiment substantially parallel to the scraper edge. As a result, a constant contact force of the stripping body 6 is provided over the entire width of the roller. The direction of the "width" of the roller in the present illustration is essentially projecting.
    Fig. 3 shows the same arrangement as Fig. 2, but in an oblique view. Again, a scraper 5 is provided, which is pressed against the roller 2 of the roller assembly. The scraper 5 comprises a stripping body 6. The stripping body 6 is designed plate-shaped. It has a substantially rectilinear wiping edge 7. This is pressed against the roller 2. In addition, the scraper 7/15 indicates ································································································· • ♦ · · t · · · ♦
    ···· 7 ......... 52059 GP / GA 5 has a bending range 8. In the bending region 8 a plurality of recesses 11 are provided. The recesses 11 are formed in the present embodiment as passing through the plate through holes. As a result, the cross-sectional area in the bending region 8 is reduced. The cross-sectional areas are those surfaces which are substantially normal to the flat sides of the stripper body and extend substantially parallel to the scraping edge. The bending region 8 also preferably runs essentially parallel to the scraping edge 7.
    The recesses 11 are executed according to an embodiment slot-shaped, wherein the longitudinal extension direction preferably extends substantially parallel to the stripping edge 7. However, rectangular, round, oval or other shaped recesses are possible.
    Preferably, the recesses are regularly distributed in the bending area. This means, for example, that the pressure between the scraper body and the roller is constant along the course of the scraper edge. Depending on the configuration of the stripper body, however, a constant bearing force of the stripper body on the roller may also be provided by unevenly distributed recesses.
    As a direct consequence of the reduction of the cross-sectional areas, the area moment of inertia and thus the bending stiffness of the entire scraper or the entire scraper body 6 is also reduced in the bending area. As a result, the advantageous effect occurs that, despite the sufficient thickness of the wiper body 6, optimum bending elasticity is achieved.
    According to a further, not shown embodiment, the recesses 11 are formed as a continuous groove or through a plurality of indentations. Also by these types of recesses, the cross-sectional area of the stripping body 6 is reduced in the bending region 8. As a further consequence, the area moment of inertia in the bending area 8 or the bending elasticity of the stripping body 6 is optimized.
    In a preferred manner, the bending region 8 is provided in a region between the clamping device 12 and the scraping edge 7. 8.15
