Abstract

A cutting blade for machines for slicing food products, particularly for high-speed slicers, has a sickle-shaped blade rotating about a rotation axis during the slicing operation and has a cutting edge that deviates from a circular shape at the radially outer circumference thereof and revolves about the rotation axis, particularly in the manner of a spiral. The edge is positioned in a cutting plane extending perpendicular to the rotation axis, and the cutting edge forms the radially outer end of a cutting surface, which forms part of the blade back side facing away from a product to be sliced during the slicing operation and includes a blade angle together with the cutting plane. The size of the blade angle varies in the circumferential direction.

Description

Die Erfindung betrifft ein Schneidmesser für Maschinen zum Aufschneiden von Lebensmittelprodukten, insbesondere für Hochgeschwindigkeitsslicer, nach dem Oberbegriff des Anspruchs 1.The invention relates to a cutting blade for machines for slicing food products, in particular for high-speed slicers, according to the preamble of claim 1.

Derartige Schneidmesser sind aus der EP 1 598 159 A1 bekannt. Die für den Einsatz an Slicern und insbesondere an Hochgeschwindigkeitsslicern verwendeten Messer besitzen meistens eine im weitesten Sinne schalen-oder schüsselartige Form, d.h. auf ihrer während des Schneidebetriebs einem aufzuschneidenden Produkt zugewandten Seite ist der Messerkörper gegenüber der durch die Schneidkante des Messers definierten Schneidebene zurückversetzt. Hierdurch wird erreicht, dass Stauchungen des aufzuschneidenden Produkts weitgehend vermieden werden. Diese einseitige Schalen- oder Schüsselform des Messers beeinflusst also während des Schneidebetriebs das Produkt selbst praktisch nicht; dem Schneidmesser ausweichen muss lediglich die gerade abgetrennte Produktscheibe, was aufgrund deren leichter Verformbarkeit jedoch unproblematisch ist.Such cutting blades are from the EP 1 598 159 A1 known. The knives used for use on slicers and in particular on high-speed slicers usually have a shell-like or bowl-like shape in the broadest sense, ie on their side facing a product to be sliced during the cutting operation, the knife body is set back from the cutting plane defined by the cutting edge of the knife. This ensures that compressions of the product to be sliced are largely avoided. Thus, this one-sided bowl or bowl shape of the knife practically does not affect the product itself during the cutting operation; To avoid the cutting blade only the product slice just separated, which is unproblematic due to their ease of deformability.

Für die Praxis kritisch ist die Größe des so genannten Schneidenwinkels. Der Schneidenwinkel ist derjenige Winkel, den eine am radial äußeren Umfang des Schneidmessers befindliche ebene Fläche, die im Folgenden auch als Schneidenfläche bezeichnet wird und deren radial außen liegendes Ende von der Schneidkante gebildet wird, mit der senkrecht zur Drehachse des Messers verlaufenden Schneidebene einschließt. Die Größe des Schneidenwinkels, also die Steilheit der Schneidenfläche, bestimmt zum einen die Beeinflussung des aufzuschneidenden Produkts und zum anderen die Art und Weise des Ablegens der jeweils abgetrennten Produktscheibe durch das Schneidmesser. Hierbei ist zu berücksichtigen, dass in Verbindung mit modernen Hochgeschwindigkeitsslicern gerade Sichelmesser für besonders hohe Schnittgeschwindigkeiten eingesetzt werden. Diese Schnittgeschwindigkeiten betragen beispielsweise bis zu 2.000 Schnitte pro Minute, d.h. mit Sichelmessern ausgestattete Hochgeschwindigkeitsslicer können ohne weiteres pro Sekunde mehr als 30 Produktscheiben abtrennen.Critical in practice is the size of the so-called cutting angle. The cutting angle is that angle which is located on the radially outer circumference of the cutting blade flat surface, which is hereinafter also referred to as cutting surface and whose radially outer end is formed by the cutting edge, with the perpendicular to Including axis of rotation of the knife extending cutting plane. The size of the cutting angle, ie the steepness of the cutting surface, determines on the one hand the influence of the product to be sliced and, on the other hand, the manner of depositing the respectively separated product slice by the cutting knife. It should be noted that in conjunction with modern Hochgeschwindigkeitsslicern straight sickle blade for particularly high speeds are used. These cutting speeds are, for example, up to 2,000 cuts per minute, ie high-speed slicers equipped with sickle knives can easily separate more than 30 product slices per second.

In der Praxis wird die Größe des Schneidenwinkels in Abhängigkeit von den produkt- und anwendungsspezifischen Gegebenheiten gewählt. Der längs der Schneidkante konstante Schneidenwinkel stellt dabei stets einen Kompromiss in Bezug auf die jeweils aufzuschneidenden Produkte dar. Ein zu großer Schneidenwinkel, d.h. eine zu steile Schneidenfläche, gilt es möglichst zu vermeiden, da hierdurch ein zu großer Druck auf das Produkt ausgeübt und das Produkt somit nicht mehr akzeptierbaren Stauchungen ausgesetzt werden könnte. Ein kleiner Schneidenwinkel dagegen, d.h. eine relativ flach eingestellte Schneidenfläche, ergibt schonende sanfte Schnitte, die das Produkt nicht unnötig stauchen. Allerdings kann mit einem derart flach eingestellten Schneidmesser nicht das in den meisten Fällen gewünschte Ablageverhalten bezüglich der jeweils abgetrennten Produktscheiben erzielt werden. Mit einem zu flach eingestellten Schneidmesser können die Produktscheiben insbesondere nicht in der eigentlich gewünschten Weise "abgekeilt" werden.In practice, the size of the cutting angle is chosen depending on the product and application specific conditions. The cutting edge angle constant along the cutting edge always represents a compromise with respect to the products to be sliced. A too large cutting angle, i. too steep a cutting surface, it should be avoided as possible, as this exerted too much pressure on the product and the product could thus be exposed to unacceptable compression. On the other hand, a small cutting angle, i. a relatively flat set cutting surface, results in gentle gentle cuts that do not compress the product unnecessarily. However, can not be achieved with such a flat set cutting blade in most cases desired storage behavior with respect to each separated product slices. In particular, if the cutting blade is set too flat, the product slices can not be "wedged" in the desired manner.

Aufgabe der Erfindung ist es, ein Schneidmesser der eingangs genannten Art derart weiterzubilden, dass es allen produkt- bzw. anwendungsspezifischen Gegebenheiten gerecht werden kann, wobei insbesondere durch das Schneidmesser verursachte Produktstauchungen minimiert und die mittels des Schneidmessers bewirkte Produktablage optimiert werden sollen.The object of the invention is to develop a cutting blade of the type mentioned in such a way that it is all product or application-specific Conditions can be met, in particular by the cutting blade caused product compressions minimized and caused by the cutting blade product storage to be optimized.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.The solution of this object is achieved by the features of claim 1.

Es wurde der bislang eingeschlagene Weg eines längs der Schneidkante konstanten Schneidenwinkels verlassen. Vielmehr erfolgt eine gezielte Änderung der Größe des Schneidenwinkels in Umfangsrichtung des Schneidmessers. Unter derartige Änderungen fallen selbstverständlich keine herstellungsbedingten Ungenauigkeiten, die zu Abweichungen von einem konstanten Sollwinkel führen. Vielmehr wird der Schneidenwinkel gezielt in einem relevanten Ausmaß längs der Schneidkante variiert, was im Schneidebetrieb spürbare Auswirkungen insbesondere auf das Ausmaß der durch das Schneidmesser verursachten Produktstauchungen sowie auf die Art und Weise der durch das Messer bewirkten Produktablage hat.It was left the path taken so far one of the cutting edge constant cutting angle. Rather, there is a targeted change in the size of the cutting angle in the circumferential direction of the cutting blade. Of course, such changes do not include any production-related inaccuracies which lead to deviations from a constant desired angle. Rather, the cutting edge angle is selectively varied to a relevant extent along the cutting edge, which has noticeable effects in the cutting operation, in particular on the extent of product upsets caused by the cutting blade and on the nature of the product tray caused by the knife.

Die Erfindung eröffnet insbesondere die Möglichkeit, die Größe des Schneidenwinkels an den Verlauf des Schneidprozesses anzupassen. Für jeden Umfangsbereich des Schneidmessers kann der Schneidenwinkel in Abhängigkeit davon gewählt werden, auf welche Weise dieser Umfangsbereich während des Schneideprozesses mit dem jeweiligen Produkt zusammenwirkt. Sichelmesser werden so eingesetzt, dass sie zu Beginn eines Schneidevorgangs mit einem Umfangsbereich in das Produkt eintauchen, an welchem der Radius - d.h. der Abstand der Schneidkante von der Drehachse des Messers - am kleinsten ist. Ab einem bestimmten Drehwinkel, der einem bestimmten Umfangsbereich der Schneidkante entspricht, ist der Eintauchprozess des Messers in das Produkt abgeschlossen. Bis zum Ende des Schneidevorgangs bewegt sich das Schneidmesser durch das Produkt hindurch, wobei der Radius aufgrund des insbesondere spiralartigen Verlaufs der Schneidkante bezüglich der Drehachse stetig zunimmt. Diese Gegebenheiten können erfindungsgemäß genutzt werden, um die Größe des Schneidenwinkels in Abhängigkeit von dem Drehwinkel bzw. dem Umfangsbereich - z.B. bezogen auf den Eintauchwinkel bzw. Eintauchbereich - zur Optimierung des Schneidprozesses insgesamt einzustellen. Grundsätzlich sind aber den Einstellmöglichkeiten keine Grenzen gesetzt. Je nach der Beschaffenheit der aufzuschneidenden Produkte und den Gegebenheiten der jeweiligen Anwendung können die Schneidmesser aufgrund der erfindungsgemäßen Variierbarkeit des Schneidenwinkels individuell optimiert werden.In particular, the invention makes it possible to adapt the size of the cutting edge angle to the course of the cutting process. For each peripheral region of the cutting blade, the cutting edge angle may be chosen depending on how this peripheral region interacts with the respective product during the cutting process. Sickle knives are used so that they are at the beginning of a Immerse the cutting process with a peripheral area in the product at which the radius - ie the distance of the cutting edge of the axis of rotation of the knife - is the smallest. From a certain angle of rotation, which corresponds to a certain peripheral region of the cutting edge, the dipping process of the knife is completed in the product. Until the end of the cutting operation, the cutting blade moves through the product, wherein the radius due to the particular spiral-like course of the cutting edge with respect to the axis of rotation increases steadily. These conditions can be used according to the invention to adjust the size of the cutting angle as a function of the angle of rotation or the peripheral region - for example, based on the plunge angle or immersion area - to optimize the overall cutting process. Basically, however, the setting options are no limits. Depending on the nature of the sliced products and the circumstances of the particular application, the cutting blades can be optimized individually due to the variability of the cutting angle according to the invention.

Erfindungsgemäß ist vorgesehen, dass sich der Schneidenwinkel über die gesamte in Umfangsrichtung verlaufende Schneidkante stetig vergrößert.According to the invention, it is provided that the cutting edge angle increases continuously over the entire circumferential cutting edge.

Bevorzugte Ausführungsformen der Erfindung sind auch in den abhängigen Ansprüchen, der Beschreibung sowie der Zeichnung angegeben.Preferred embodiments of the invention are also set forth in the dependent claims, the description and the drawings.

Erfindungsgemäß wind vorgesehen, dass das Schneidmesser eine bestimmungsgemäße Drehrichtung aufweist, wobei sich der Schneidenwinkel entgegen der Drehrichtung vergrößert. Mit anderen Worten nimmt während des Schneidevorgangs der Schneidenwinkel zu, d.h. die von der Schneidkante radial außen begrenzte Schneidenfläche auf der Messerrückseite wird während des Schneidevorgangs zunehmend steiler.Wind provided according to the invention that the cutting blade has a proper direction of rotation, wherein the cutting angle increases counter to the direction of rotation. In other words, during the cutting process, the cutting edge angle increases, ie the cutting edge on the rear side of the blade which is radially outwardly bounded by the cutting edge becomes progressively steeper during the cutting process.

Bei einem Sichelmesser, wie es vorstehend beschrieben wurde, d.h. das während des Schneidevorgangs mit dem kleinsten Radius in das Produkt eintaucht, bedeutet dies somit, dass sich in dieser Ausführungsform der Schneidenwinkel mit zunehmendem radialen Abstand der Schneidkante von der Drehachse vergrößert. Dies stellt eine konkrete Ausgestaltung des allgemeinen, hier ebenfalls unabhängig beanspruchten Gedankens dar, die Größe des Schneidenwinkels in Abhängigkeit von dem radialen Abstand der Schneidkante von der Drehachse des Schneidmessers, also von dem Drehwinkel des Messers, zu wählen, d.h. den Schneidenwinkel als eine Funktion des Drehwinkels zu definieren.For a sickle blade as described above, i. which dips into the product during the cutting operation with the smallest radius, this means that in this embodiment, the cutting angle increases with increasing radial distance of the cutting edge of the rotation axis. This represents a concrete embodiment of the general, here also independently claimed idea to choose the size of the cutting angle in dependence on the radial distance of the cutting edge of the axis of rotation of the cutting blade, ie from the rotation angle of the knife, i. to define the cutting angle as a function of the angle of rotation.

Erfindungsgemäß weist die Schneidkante einen Eintauchbereich auf, mit dem das Schneidmesser bei bestimmungsgemäßem Gebrauch während des Schneidebetriebs in ein aufzuschneidendes Produkt eintaucht, wobei der Schneidenwinkel im Eintauchbereich am kleinsten ist.According to the invention, the cutting edge has an immersion region, with which the cutting blade, when used as intended, is immersed in a product to be sliced during the cutting operation, wherein the cutting angle is smallest in the immersion region.

Diese Ausführungsform macht sich die Erkenntnis zunutze, dass Produktstauchungen durch das Schneidmesser in dem Moment am größten sind, wenn das Schneidmesser in das Produkt eintaucht. Indem für den Eintauchbereich des Schneidmessers ein vergleichsweise kleiner Schneidenwinkel und insbesondere der kleinste am Schneidmesser ausgebildete Schneidenwinkel gewählt wird, werden Produktstauchungen durch das erfindungsgemäße Schneidmesser folglich minimiert. Ausgehend von dem Eintauchbereich kann dann der Schneidenwinkel insbesondere stetig zunehmen. Hierdurch wird erreicht, dass während des weiteren Verlaufs des Schneidevorgangs und insbesondere nach Abschluss der Eintauchphase der Schneidenwinkel eine Größe bzw. Steilheit aufweist, die für ein gewünschtes Abkeilen der jeweiligen Produktscheibe bzw. für ein schnelleres und besseres Ablegen der Produktscheibe sorgt, als dies mit einem durchgehend flachen Schneidenwinkel der Fall wäre.This embodiment takes advantage of the recognition that product upsets through the cutting blade are largest at the moment the cutting knife is immersed in the product. By selecting a comparatively small cutting angle for the immersion region of the cutting blade and, in particular, the smallest cutting angle formed on the cutting blade, product upsets are consequently minimized by the cutting blade according to the invention. Starting from the immersion region, the cutting angle can then increase steadily in particular. This ensures that, during the further course of the cutting process and in particular after completion of the dipping phase, the cutting edge angle has a size or steepness corresponding to a desired wedge of the respective product wafer or for a faster and ensures better storage of the product disc, as would be the case with a consistently flat cutting angle.

Die Änderung des Schneidenwinkels erfolgt insbesondere ohne Ausbildung von Stufen in der Schneidenfläche. Hierdurch wird das Produkt während des Aufschneidens so wenig wie möglich gestört.The change of the cutting angle takes place in particular without the formation of steps in the cutting surface. As a result, the product is disturbed as little as possible during slicing.

Grundsätzlich kann das Schneidenwinkelprofil, d.h. der Verlauf der Größe des Schneidenwinkels längs der Schneidkante, beliebig ausgestaltet sein. Die Rate, mit der sich der Schneidenwinkel ändert, kann konstant, in Abhängigkeit z.B. von dem Drehwinkel des Messers, also von dem jeweiligen Umfangsbereich der Schneidkante, aber auch für verschiedene Umfangsbereiche unterschiedlich groß sein.Basically, the cutting angle profile, i. the course of the size of the cutting angle along the cutting edge, be designed as desired. The rate at which the cutting angle changes may be constant, depending on e.g. be different in size from the angle of rotation of the blade, so from the respective peripheral region of the cutting edge, but also for different peripheral regions.

In einem konkreten Ausführungsbeispiel kann vorgesehen sein, dass sich der Schneidenwinkel in einem Bereich von etwa 20° bis 30° ändert. Grundsätzlich kann die Messerschneide aber auch flachere oder steilere Bereiche aufweisen.In a specific embodiment, it may be provided that the cutting angle changes in a range of about 20 ° to 30 °. In principle, however, the knife edge can also have flatter or steeper areas.

Je nach konkreter Ausgestaltung der Messerrückseite kann vorgesehen sein, dass die Schneidenfläche eine Breite aufweist, die in Abhängigkeit von der Größe des Schneidenwinkels variiert.Depending on the specific design of the rear of the knife can be provided that the cutting surface has a width that varies depending on the size of the cutting edge angle.

Beispielsweise kann die Breite der Schneidenfläche in einem Bereich von 0,5 mm bis 1,5 mm variieren.For example, the width of the cutting surface may vary within a range of 0.5 mm to 1.5 mm.

Was die wirksame Länge der Schneidkante in Umfangsrichtung anbetrifft, so erstreckt sich die Schneidkante insbesondere über einen Winkel zwischen 180° und 360°. In einer möglichen Ausgestaltung beträgt die Länge der Schneidkante in Umfangsrichtung ungefähr 270°.As regards the effective length of the cutting edge in the circumferential direction, the cutting edge extends in particular over an angle between 180 ° and 360 °. In one possible embodiment, the length of the cutting edge in the circumferential direction is approximately 270 °.

Des Weiteren kann erfindungsgemäß vorgesehen sein, dass radial innerhalb der Schneidenfläche eine weitere Fläche ausgebildet ist, die einen Teil der Messerrückseite bildet und mit der Schneidebene einen Winkel einschließt, der in Umfangsrichtung konstant und kleiner als der kleinste Schneidenwinkel ist.Furthermore, it can be provided according to the invention that a further surface is formed radially inside the cutting surface, which forms part of the knife back and forms an angle with the cutting plane, which is constant in the circumferential direction and smaller than the smallest cutting angle.

Die Schneidenfläche und die weitere Fläche können unmittelbar aneinander angrenzen. Alternativ ist es aber auch möglich, dass zwischen der Schneidenfläche und der weiteren Fläche wenigstens eine Übergangsfläche ausgebildet ist.The cutting surface and the further surface can adjoin one another directly. Alternatively, it is also possible that at least one transition surface is formed between the cutting surface and the further surface.

Auf die Herstellung des erfindungsgemäßen Schneidenmessers soll hier nur insoweit eingegangen werden, als vorzugsweise vorgesehen ist, dass die Schneidenfläche durch Anschleifen eines entsprechend hergestellten Vorprodukts gebildet ist.The preparation of the cutting blade according to the invention should be discussed here only insofar as it is preferably provided that the cutting surface is formed by grinding a precursor produced accordingly.

Die Erfindung wird im Folgenden beispielhaft unter Bezugnahme auf die Zeichnung beschrieben. Es zeigen:

The invention will now be described by way of example with reference to the drawings. Show it:
Fig. 1
a schematic plan view of an inventive cutting blade,
Fig. 2
partially a cross-sectional view of a cutting blade according to the invention, and
Fig. 3
several cross-sectional views of a cutting blade according to the invention at different peripheral regions.

Das in Fig. 1 dargestellte erfindungsgemäße Sichelmesser umfasst eine spiralartig um eine Drehachse 11 umlaufende Schneidkante 13, die sich etwa über einen Winkelbereich von 270° erstreckt und in einer senkrecht zur Drehachse 11 verlaufenden Schneidebene liegt. Der Abstand der Schneidkante 13 von der Drehachse 11, also der Radius R des Schneidmessers, nimmt kontinuierlich zu, und zwar entgegen einer Drehrichtung T, in der das Schneidmesser während des Schneidebetriebs um die Drehachse 11 rotiert.This in Fig. 1 illustrated sickle blade according to the invention comprises a spiral about a rotation axis 11 encircling cutting edge 13, which extends approximately over an angular range of 270 ° and is located in a direction perpendicular to the axis of rotation 11 extending cutting plane. The distance of the cutting edge 13 from the axis of rotation 11, so the radius R of the cutting blade, increases continuously, namely against a rotational direction T, in which the cutting blade rotates about the axis of rotation 11 during the cutting operation.

Das erfindungsgemäße Sichelmesser ist zum Einsatz an einem Hochgeschwindigkeitsslicer bestimmt. Diese Slicer sind mit einem so genannten Schneid- oder Messerkopf versehen, der eine die Drehachse 11 festlegende Antriebswelle für das Schneidmesser aufweist. Zur Aufnahme der Antriebswelle ist in dem Schneidmesser die in der Fig. 1 dargestellte Öffnung 29 ausgebildet. Weitere Befestigungsmittel, wie insbesondere um die Öffnung 29 herum angeordnete Bohrungen zum Verschrauben des Schneidmessers am Schneidkopf des Slicers sind der Einfachheit halber nicht dargestellt.The sickle knife according to the invention is intended for use on a high speed slicer. These slicers are provided with a so-called cutting or knife head, which has a rotary shaft 11 defining drive shaft for the cutting blade. To accommodate the drive shaft is in the cutting blade in the Fig. 1 illustrated opening 29 is formed. Other fastening means, such as in particular arranged around the opening 29 around holes for screwing the cutting blade on the cutting head of the slicer are not shown for simplicity.

Derartige Sichelmesser zeichnen sich dadurch aus, dass sie - wie bereits im Einleitungsteil erwähnt - mit einem Bereich A in das aufzuschneidende Produkt eintauchen, für den der Radius R am kleinsten ist. Während des Schneidevorgangs bewegt sich das rotierende Schneidmesser durch das Produkt hindurch, wobei nacheinander die hier lediglich beispielhaft angedeuteten Umfangsbereiche A, B, C und D des Messers mit dem Produkt zusammenwirken. Für den Umfangsbereich D ist der Radius R des Messers am größten.Such sickle blades are characterized by the fact that they - as already mentioned in the introductory part - dive with a range A in the aufzuschneidende product for which the radius R is the smallest. During the cutting process, the rotating cutting blade moves through the product, wherein successively indicated here only by way of example peripheral areas A, B, C and D of the knife with the product interact. For the peripheral region D, the radius R of the blade is greatest.

Wie aus Fig. 2 ersichtlich, besitzt das erfindungsgemäße Sichelmesser eine schalen- oder schüsselartige Form. Indem auf diese Weise die Messerinnenseite 27 gegenüber der senkrecht zur Drehachse 11 verlaufenden Schneidebene 15 zurückversetzt ist, ist auf der während des Schneidebetriebs dem aufzuschneidenden Produkt 19 zugewandten Seite des Messers ein Freiraum 25 vorhanden. Durch diese Schalen- oder Schüsselform des Messers werden Produktstauchungen bereits erheblich reduziert.How out Fig. 2 can be seen, the sickle blade according to the invention has a bowl or dish-like shape. By in this way the knife inner side 27 is set back relative to the cutting plane 15 running perpendicular to the axis of rotation 11, a free space 25 is provided on the side of the knife facing the product 19 to be sliced during the cutting operation. This bowl or bowl shape of the knife already significantly reduces product compression.

Die Messerrückseite 21 wird radial außen von einer ebenen Schneidenfläche 17 gebildet, die radial außen von der die Schneidebene 15 festlegenden Schneidkante 13 begrenzt wird. Radial innen schließt sich an die Schneidenfläche 17 eine weitere ebene Fläche 23 an. Der Querschnitt des erfindungsgemäßen Schneidmessers im Anschluss an die Schneidenfläche 17 kann von der in Fig. 2 dargestellten Ausführungsform abweichen und grundsätzlich beliebig variieren. Das diesbezügliche konkrete Profil des Messers wird auch im Hinblick auf eine möglichst gute Eigenstabilität des Messers gewählt.The blade rear side 21 is formed radially outwardly by a flat cutting surface 17 which is bounded radially outwardly by the cutting edge 15 defining the cutting edge 13. Radially inside, the cutting surface 17 is followed by a further flat surface 23. The cross section of the cutting blade according to the invention subsequent to the cutting surface 17 may be of the in Fig. 2 deviate embodiment shown and basically vary as desired. The related concrete profile of the knife is also chosen with regard to the best possible inherent stability of the knife.

Die Schneidenfläche 17 schließt mit der Schneidebene 15 einen Winkel α ein, der größer ist als der Winkel β zwischen der Schneidebene 15 und der weiteren Fläche 23. Die Schneidenfläche 17 besitzt des Weiteren eine Breite W.The cutting surface 17 includes with the cutting plane 15 an angle α, which is greater than the angle β between the cutting plane 15 and the further surface 23. The cutting surface 17 further has a width W.

Erfindungsgemäß ist der Schneidenwinkel α längs der Schneidkante 13 nicht konstant. Vielmehr ist vorgesehen, dass der Schneidenwinkel in Abhängigkeit von dem Radius R der Schneidkante 13 variiert.According to the invention, the cutting angle α along the cutting edge 13 is not constant. Rather, it is provided that the cutting angle varies depending on the radius R of the cutting edge 13.

Fig. 3 veranschaulicht ein mögliches Ausführungsbeispiel für ein derartiges "Profil" des Schneidenwinkels in Umfangsrichtung. Die Fig. 3a - 3d zeigen jeweils einen Querschnitt des Schneidmessers entsprechend Fig. 2 für einen der in Fig. 1 angedeuteten Umfangsbereiche A - D. Fig. 3 illustrates a possible embodiment for such a "profile" of the cutting angle in the circumferential direction. The Fig. 3a - 3d each show a cross section of the cutting blade accordingly Fig. 2 for one of the in Fig. 1 indicated peripheral areas A - D.

Gemäß Fig. 3a ist im Eintauchbereich A des Schneidmessers, wo der Radius am kleinsten ist, der Schneidenwinkel α1 ebenfalls am kleinsten. Da in diesem Ausführungsbeispiel der Winkel β zwischen der Schneidebene 15 und der an die Schneidenfläche 17 angrenzenden weiteren Fläche 23 in Umfangsrichtung konstant ist und zwischen Schneidenfläche 17 und weiterer Fläche 23 an keiner Stelle in Umfangsrichtung ein oder mehrere Übergangsflächen vorgesehen sind, ist die Breite W der Schneidenfläche 17 im Eintauchbereich A am größten.According to Fig. 3a is in the immersion area A of the cutting blade, where the radius is smallest, the cutting angle α1 also smallest. Since in this embodiment, the angle β between the cutting plane 15 and adjacent to the cutting surface 17 further surface 23 is constant in the circumferential direction and between cutting surface 17 and further surface 23 at any point in the circumferential direction one or more transition surfaces are provided, the width W is the Cutting surface 17 in the immersion region A largest.

Mit zunehmendem Drehwinkel (entgegen der Drehrichtung T; Fig. 1) verläuft die Schneidenfläche 17 zunehmend steiler, d.h. der Schneidenwinkel α nimmt zu. Entsprechend nimmt die Breite W der Schneidenfläche 17 ab.With increasing angle of rotation (contrary to the direction of rotation T; Fig. 1 ), the cutting surface 17 is progressively steeper, ie the cutting angle α increases. Accordingly, the width W of the cutting surface 17 decreases.

Mögliche Werte für den Schneidenwinkel α an den verschiedenen Umfangsbereichen des Schneidmessers lauten wie folgt: Eintauchbereich A: α1 = 20° Umfangsbereich B: α2 = 23° Umfangsbereich C: α3 = 26° Umfangsbereich D: α4 = 30° Possible values for the cutting angle α at the various peripheral areas of the cutting blade are as follows: Immersion area A: α1 = 20 ° Peripheral area B: α2 = 23 ° Peripheral area C: α3 = 26 ° Peripheral area D: α4 = 30 °

Der in Umfangsrichtung, also längs der Schneidkante 13, konstante Winkel β zwischen Schneidebene 15 und weiterer Fläche 23 beträgt in diesem Ausführungsbeispiel 12°.The in the circumferential direction, ie along the cutting edge 13, constant angle β between the cutting plane 15 and further surface 23 is 12 ° in this embodiment.

Diese Werte für die Winkel α und β sind rein beispielhafter Art und können je nach aufzuschneidenden Produkten und konkreten Anwendungen beliebig variieren, und zwar nicht nur hinsichtlich der absoluten Größen, sondern auch in Bezug auf den grundsätzlichen Verlauf des "Winkelprofils" in Umfangsrichtung.These values for the angles .alpha. And .beta. Are purely exemplary in nature and may vary as desired depending on the products to be sliced and the specific applications, not only in terms of absolute sizes but also in terms of the general course of the "angle profile" in the circumferential direction.

Mit dem hier dargestellten Ausführungsbeispiel kann erreicht werden, dass aufgrund der flachen Schneidenfläche 17 im Eintauchbereich A Produktstauchungen beim Eintauchen des Messers in das Produkt weitestgehend vermieden werden, wobei aufgrund der zunehmenden Steilheit der Schneidenfläche 17 in Umfangsrichtung gleichzeitig eine schnellere und bessere Produktablage erzielt wird als mit einem durchgehend flachen Schneidenwinkel.With the embodiment shown here can be achieved that due to the flat cutting surface 17 in the immersion A product compression when immersing the knife are largely avoided in the product, which due to the increasing steepness of the cutting surface 17 in the circumferential direction at the same time faster and better product storage is achieved than with a continuous flat cutting angle.
