Description

Die vorliegende Erfindung betrifft ein Schneidmesser für Maschinen zum Aufschneiden von Lebensmittelprodukten, insbesondere für Hochgeschwindigkeitsslicer, wobei das Schneidmesser ein während des Schneidebetriebes um eine Drehachse rotierendes Sichelmesser ist, das an seinem radial äußeren Umfang eine von einer Kreisform abweichende, insbesondere nach Art einer Spirale um die Drehachse umlaufende, Schneidkante aufweist, die in einer senkrecht zur Drehachse verlaufenden Schneidebene liegt, wobei die Schneidkante das radial außen liegende Ende der Schneidenfläche bildet, die einen Teil der während des Schneidebetriebs von einem aufzuschneidenden Produkt abgewandten Messerrückseite bildet und mit der Schneidebene einen Schneidenwinkel einschließt, und wobei die Größe des Schneidenwinkels in Umfangsrichtung des Schneidmessers variiert. Des Weiteren betrifft die vorliegende Erfindung die Verwendung des Schneidmessers zum Schneiden von Lebensmittelprodukten.The present invention relates to a cutting blade for machines for slicing food products, in particular for high-speed slicer, wherein the cutting blade is a rotary knife rotating about a rotation axis during the cutting operation, which at its radially outer circumference deviates from a circular shape, in particular in the manner of a spiral around the The cutting edge is the radially outer end of the cutting surface, which forms part of the rear side facing away from a product aufzuschneids product during cutting operation and includes a cutting angle with the cutting plane, and wherein the size of the cutting angle varies in the circumferential direction of the cutting blade. Furthermore, the present invention relates to the use of the cutting blade for cutting food products.

Derartige Schneidmesser sind aus dem Stand der Technik, beispielsweise der EP 1 598 159 bekannt. Weiterer Stand der Technik ist die EP 08 785 722 A2 . Der Fachmann ist fortlaufend bestrebt Schneidmesser zur Verfügung zu stellen, bei denen:

  • beim Schneiden das Produkt möglichst wenig gestaucht wird,
  • die abgeschnittene Scheibe die gewünschte Flugbahn einnimmt und/oder
  • die eine möglichst lange Standzeit aufweisen
und/oder die vergleichsweise einfach herzustellen sind.Such cutting blades are known from the prior art, for example EP 1 598 159 known. Further prior art is the EP 08 785 722 A2 , The person skilled in the art constantly endeavors to provide cutting knives in which:
  • when cutting the product is compressed as little as possible,
  • the cut disc occupies the desired trajectory and / or
  • which have the longest possible service life
and / or which are relatively easy to manufacture.

Es war deshalb die Aufgabe der vorliegenden Erfindung ein derartiges Messer zur Verfügung zu stellen.It was therefore the object of the present invention to provide such a knife.

Gelöst wird die Aufgabe mit einem Schneidmesser gemäß der Ansprüche 1-4. Die vorliegende Erfindung betrifft ein Schneidmesser, das zum Aufschneiden von Lebensmittelprodukten, insbesondere für Hochgeschwindigkeitsslicer eingesetzt wird. Bei Hochgeschwindigkeitsslicern wird das Produkt, beispielsweise ein Wurst-, Schinken- oder Käseriegel, in Richtung des rotierenden Schneidmessers kontinuierlich oder intermittierend transportiert, das von dem vorderen Ende des Lebensmittelproduktes Lebensmittelscheiben abschneidet. Diese Lebensmittelscheiben fallen sodann beispielsweise auf einen Ablagetisch, auf dem sie zu einer Portion von beispielsweise zehn Scheiben konfiguriert werden. Sobald eine derartige Portion fertiggestellt ist, wird diese aus dem Schneidbereich des Messers abtransportiert und eine neue Portion kann aufgeschnitten werden.The problem is solved with a cutting blade according to claims 1-4. The present invention relates to a cutting blade which is used for slicing food products, especially for high-speed slicers. At high speed slurries, the product, for example a sausage, ham or cheese bar, is transported continuously or intermittently in the direction of the rotating cutting blade which cuts food slices from the front end of the food product. These food slices then fall, for example, on a storage table on which they are configured to a serving of, for example, ten slices. Once such a portion is finished, it is removed from the cutting area of the knife and a new portion can be cut open.

Erfindungsgemäß ist das Schneidmesser ein Sichelmesser. Das Messer kann eine schalen- oder schüsselartige Form oder eine Hohlstruktur aufweisen. An seinem radial äußeren Umfang weist das Schneidmesser eine Schneidkante auf, die in einer senkrecht zur Drehachse des Schneidmessers verlaufenden Schneidebene liegt. Die Schneidkante bildet dabei das radial außen liegende Ende einer Schneidfläche, die einen Teil der während des Schneidbetriebs von dem aufzuschneidenden Produkt abgewandten Messerrückseite bildet und mit der Schneidebene einen Schneidenwinkel einschließt. Erfindungsgemäß variiert die Größe dieses Schneidenwinkels in Umfangsrichtung des Schneidmessers, wobei sich der Scheidenwinkel aber nur in Teilbereichen der in Umfangsrichtung verlaufenden Schneidkante verändert.According to the invention, the cutting blade is a sickle blade. The knife may have a bowl or bowl-like shape or a hollow structure. At its radially outer periphery, the cutting blade has a cutting edge which lies in a cutting plane running perpendicular to the axis of rotation of the cutting blade. In this case, the cutting edge forms the radially outer end of a cutting surface, which forms part of the rear side of the knife facing away from the product to be sliced during the cutting operation and encloses a cutting angle with the cutting plane. According to the invention varies the size of this cutting angle in the circumferential direction of the cutting blade, wherein the Sheath angle but changed only in partial areas of the circumferential cutting edge.

Dadurch, dass sich der Schneidenwinkel nur in Teilbereichen der in Umfangsrichtung verlaufenden Schneidkante verändert, ist das erfindungsgemäße Schneidmesser kostengünstiger herzustellen als Schneidmesser wie sie beispielsweise in der EP 08 785 722 A2 offenbart sind. Desweiteren hat sich herausgestellt, dass es für das Schneidverhalten bzw. die Flugbahn der abgeschnittenen Lebensmittelscheibe positiv ist, wenn sich der Schneidenwinkel nur in Teilbereichen der in Umfangsrichtung verlaufenden Schneidkante verändert und nicht die gesamte Schneidkante einen sich verändernden Schneidenwinkel aufweist.Due to the fact that the cutting edge angle changes only in partial regions of the cutting edge extending in the circumferential direction, the cutting blade according to the invention is less expensive to manufacture than the cutting blade of the type described, for example, in US Pat EP 08 785 722 A2 are disclosed. Furthermore, it has been found that it is positive for the cutting behavior or the trajectory of the cut food disc when the cutting angle changed only in partial areas of the circumferential cutting edge and not the entire cutting edge has a changing cutting angle.

Gemäß der vorliegenden Erfindung verändert sich der Schneidenwinkel unstetig. Diese unstetige Veränderung des Schneidenwinkels kann sich nur über Teilbereiche der Schneidkante oder über die gesamte Länge erstecken. Unstetig im Sinne der Erfindung bedeutet, dass sie nicht stetig im mathematischen Sinn ist, d.h. dass der Schneidenwinkel sich beispielsweise sprunghaft, mit einem Absatz und/oder knickartig verändert.According to the present invention, the cutting angle changes discontinuously. This discontinuous change in the cutting angle can only extend over partial areas of the cutting edge or over the entire length. Discontinuous in the sense of the invention means that it is not continuous in the mathematical sense, i. that the cutting angle changes, for example, suddenly, with a heel and / or kink-like.

Durch diese Unstetigkeitsstellen kann der Schneidenwinkel in bestimmen Umfangsbereichen konstant bleiben und sich dann beispielsweise absatzweise ändern. Dadurch ist die Herstellung und das Schärfen des Schneidmessers wesentlich einfacher als bei einer stetigen Veränderung des Schneidenwinkels über den gesamten Verlauf der Schneidkante, wie er beispielsweise in der EP 08 785 722 A2 beansprucht ist. Außerdem erhält die abzuschneidende Lebensmittelscheibe durch die Unstetigkeitsstelle des Messers einen zusätzlichen Impuls, der es beispielsweise von dem Produkt wegbewegt und/oder formt.Through these points of discontinuity, the cutting edge angle can remain constant in certain peripheral regions and then change, for example, intermittently. As a result, the production and sharpening of the cutting blade is much easier than with a continuous change in the cutting angle over the entire course of the cutting edge, as he, for example, in the EP 08 785 722 A2 is claimed. In addition, the food slice to be cut off receives an additional impulse from the point of discontinuity of the knife, which for example moves it away from the product and / or forms it.

Die zu diesem Gegenstand der vorliegenden Erfindung gemachten Ausführungen gelten für die anderen Gegenstände der vorliegenden Erfindung gleichermaßen und umgekehrt.The statements made on this subject of the present invention apply equally to the other objects of the present invention and vice versa.

Vorzugsweise befindet sich eine Unstetigkeitsstelle von einem Übergang von einem Schneidenwinkel zu einem anderen Schneidenwinkel.Preferably, a point of discontinuity is from a transition from one cutting edge angle to another cutting angle.

Die folgenden Ausführungen gelten für alle Gegenstände der vorliegenden Erfindung gleichermaßen. Erfindungsgemäß vergrößert sich der Schneidenwinkel entgegen der Drehrichtung des Schneidmessers.The following statements apply equally to all articles of the present invention. According to the invention, the cutting edge angle increases counter to the direction of rotation of the cutting blade.

Weiterhin bevorzugt vergrößert sich der Schneidenwinkel mit zunehmendem radialen Abstand der Schneidkante von der Drehachse des Schneidmessers.Further preferably, the cutting angle increases with increasing radial distance of the cutting edge of the axis of rotation of the cutting blade.

Erfindungsgemäß weist die Schneidkante mindestens einen, vorzugsweise mehrere Abschnitt(e) aufweist, in dem/denen sich der Schneidenwinkel nicht verändert. Vorzugsweise umfasst ein Abschnitt 1 - 120°, besonders bevorzugt 5 - 90°, ganz besonders bevorzugt 10 - 70° und am meisten bevorzugt 6 -30°. Erfindungsgemäß weist der Schneidfläche Unstetigkeitsstellen auf.According to the invention, the cutting edge has at least one, preferably a plurality of sections in which the cutting angle does not change. Preferably, a section comprises 1 - 120 °, more preferably 5 - 90 °, most preferably 10 - 70 ° and most preferably 6 - 30 °. According to the invention, the cutting surface has points of discontinuity.

Vorzugsweise beträgt der Schneidenwinkel 15 - 45°, besonders bevorzugt 20 -30°.The cutting angle is preferably 15-45 °, particularly preferably 20-30 °.

Ein weiterer Gegenstand der vorliegenden Erfindung ist die Verwendung des erfindungsgemäßen Schneidmessers zum Aufschneiden eines Lebensmittelproduktes in Lebensmittelscheiben, wobei sich das Schneidmesser beim Schneiden dreht.Another object of the present invention is the use of the cutting blade according to the invention for slicing a food product into food slices, wherein the cutting blade rotates during cutting.

Im Folgenden werden die Erfindungen anhand der Figuren 1 bis 4 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein. Die Erläuterungen gelten für alle Gegenstände der vorliegenden Erfindung gleichermaßen.

  • Figur 1 zeigt eine Draufsicht auf das erfindungsgemäße Schneidmesser.
  • Figur 2 zeigt teilweise eine Querschnittsansicht eines erfindungsgemäßen Schneidmessers.
  • Figur 3 zeigt mehrere Querschnittsansichten eines erfindungsgemäßen Schneidmessers an unterschiedlichen Umfangsbereichen.
  • Figur 4 zeigt eine Schneidmesserschleifvorrichtung.
In the following, the inventions are based on the FIGS. 1 to 4 explained. These explanations are merely exemplary and do not limit the general inventive concept. The explanations apply equally to all articles of the present invention.
  • FIG. 1 shows a plan view of the cutting blade according to the invention.
  • FIG. 2 partially shows a cross-sectional view of a cutting blade according to the invention.
  • FIG. 3 shows several cross-sectional views of a cutting blade according to the invention at different peripheral regions.
  • FIG. 4 shows a Schneidmesserschleifvorrichtung.

Bei dem Schneidmesser gemäß Figur 1 handelt es sich um ein sogenanntes Sichelmesser, das sich um eine Drehachse 1 in der durch den Pfeil 6 gekennzeichneten Richtung dreht und dabei mittels seiner Schneidkante 2 in ein Produkt 4 eintaucht und sodann eine Scheibe von dem Produkt abschneidet. Das erfindungsgemäße Schneidmesser wird mittels der Ausnehmung 5 und/oder nicht dargestellten Befestigungsmitteln an einer sich drehenden Welle einer Aufschneidevorrichtung befestigt. Mit dem Bezugszeichen R ist der Abstand der Schneidkante von der Drehachse des Schneidmessers dargestellt, der sich entgegen der Drehrichtung 6 des Schneidmessers vergrößert, so dass das Messer spiralförmig ausgebildet ist. Üblicherweise taucht das Produkt mit dem mit dem Bezugszeichen A gekennzeichneten Bereich in das Produkt ein und mittels diesem und den Bereichen B, C und/oder D wird die Lebensmittelscheibe von dem Produkt abgetrennt. Der Übergang von einem Bereich zum anderen ist durch das Bezugszeichen 19 symbolisiert. Der Fachmann versteht, dass bei einer Umdrehung des Messers mehrere Scheiben von mehreren nebeneinander liegenden Produkten abgeschnitten werden können.In the cutting blade according to FIG. 1 it is a so-called sickle blade, which rotates about a rotation axis 1 in the direction indicated by the arrow 6 and thereby dips by means of its cutting edge 2 in a product 4 and then cuts off a slice of the product. The cutting blade according to the invention is fastened by means of the recess 5 and / or fastening means (not shown) to a rotating shaft of a slicing device. The reference symbol R shows the distance of the cutting edge from the axis of rotation of the cutting blade, which increases counter to the direction of rotation 6 of the cutting blade, so that the blade is formed spirally. The product usually dips into the product at the area marked with the reference symbol A, and by means of this and the regions B, C and / or D, the food disc is separated from the product. The transition from one area to the other is symbolized by the reference numeral 19. The person skilled in the art will understand that several discs of several adjacent products can be cut off during one rotation of the knife.

Anhand von Figur 2 ist erkennbar, dass das erfindungsgemäße Sichelmesser in dem vorliegenden Fall eine schalen- oder schüsselartige Form aufweist. Dadurch ist die Messerinnenseite gegenüber der senkrecht zur Drehachse 1 verlaufenden Schneidebene 7 zurückgesetzt, so dass das ein Freiraum 20 entsteht und das Schneidmesser das Produkt somit nur teilweise berührt. Auf der Messerrückseite 8 weist das erfindungsgemäße Messer eine Oberfläche 9 auf. Ebenfalls auf der Rückseite schließt sich an die Schneidkante 2 eine Schneidfläche 3 an, die in einem bestimmten Schneidenwinkel α vorgesehen ist, wobei der Schneidenwinkel α der Winkel zwischen der Schneidebene 7 und der Schneidenfläche 3 ist. Dieser Winkel α ist in der Regel größer als der Winkel β zwischen der Scheidebene 7 und der Oberfläche 9 der Messerrückseite. Erfindungsgemäß verändert sich der Schneidenwinkel α nun entlang der Schneidkante 2 aber nur in einem Teilbereich der in Umfangsrichtung verlaufenden Schneidkante 2. Dies ist in Figur 3 dargestellt. Figur 3a zeigt den Eintauchbereich A, die Figuren 3b - 3d die Abschnitte B - D gemäß Figur 1. In dem Eintauchbereich A hat der Schneidenwinkel beispielsweise einen konstanten Wert von α1 und in den weiteren Bereichen B, C und D einen konstanten Wert α2, α3 bzw. α4, wobei sich die Schneidenwinkel vorzugsweise an der Unstetigkeitsstelle 19 jeweils unstetig verändern. Gemäß einer alternativen Ausführungsform hat das Messer im Eintauchbereich beispielsweise einen Schneidenwinkel von α1, und in den Bereichen "B", "C" und "D" sind die Schneidenwinkel α2, α3 und α4 jeweils identisch. Gemäß einer weiteren alternativen Ausführungsform ist es auch möglich, dass der Schneidenwinkel in den Abschnitten "B" und "C" konstant ist und lediglich im Bereich "A" kleiner und im Bereich "D" größer ist. Der Fachmann erkennt, dass noch viele andere Kombinationen möglich sind. Es muss erfindungsgemäß nur gewährleistet sein, dass die Änderung der Schneidenwinkel von einem Bereich zum anderen unstetig ist und dass sich der Schneidenwinkel nur in Teilbereichen der Schneidkante verändert und dass sich der Schneidenwinkel entgegen der Drehrichtung des Schneidmessers vergrößert.Based on FIG. 2 It can be seen that the sickle knife according to the invention in the present case has a bowl-like or bowl-like shape. This is the result Inside the knife opposite to the perpendicular to the rotation axis 1 extending cutting plane 7 reset, so that a free space 20 is formed and the cutting blade thus only partially touches the product. On the back of the knife 8, the knife according to the invention has a surface 9. Also on the back of the cutting edge 2 is followed by a cutting surface 3, which is provided in a certain cutting angle α, wherein the cutting angle α is the angle between the cutting plane 7 and the cutting surface 3. This angle α is usually greater than the angle β between the sheath 7 and the surface 9 of the back of the knife. According to the invention, the cutting angle α now changes along the cutting edge 2 but only in a partial region of the cutting edge 2 running in the circumferential direction FIG. 3 shown. FIG. 3a shows the immersion area A, the Figures 3b - 3d the sections B - D according to FIG. 1 , In the immersion region A, for example, the cutting angle has a constant value of α1 and in the other regions B, C and D a constant value α2, α3 or α4, wherein the cutting angles preferably change discontinuously at the point of discontinuity 19. For example, according to an alternative embodiment, the knife has a cutting angle of α1 in the immersion region, and in the regions "B", "C" and "D" the cutting angles α2, α3 and α4 are identical. According to a further alternative embodiment, it is also possible that the cutting angle in the sections "B" and "C" is constant and is smaller only in the area "A" and larger in the area "D". The person skilled in the art recognizes that many other combinations are possible. It must only be ensured according to the invention that the change in the cutting edge angle is discontinuous from one region to another and that the cutting angle changes only in partial regions of the cutting edge and that the cutting angle increases counter to the direction of rotation of the cutting blade.

Figur 4 zeigt eine Schneidmesserschleifvorrichtung. Das Schneidmesser 10 wird an einer sich drehenden Welle drehfest vorgesehen, an der auch eine Kurvenscheibe 11 drehfest angeordnet ist. Die Schneidfläche 3 des Schneidmessers 10 wird mittels eines Schleifmittels 14, hier eine sich drehende Schleifscheibe 14, das an der Schneidfläche 3 des Schneidmessers anliegt, geschliffen. Diese Schleifscheibe 14 wird mittels eines Federmittels 16 gegen einen Anschlag 17 gedrückt und ist in ihrem Winkel µ relativ zur Horizontalen einstellbar. Diese Einstellung erfolgt mittels eines Nocken 13, hier einer Rolle 13, die längs verschieblich in einem Gleitlager 12 gelagert ist, so dass der Hebel 21, der mit der Rolle 13 verbunden ist, die durch den Doppelpfeil gekennzeichnete Bewegung durchführen kann. Dieser Hebel 21 ist mittels eines Verbindungsmittels 18 mit dem Schleifmittel 14, 15 verbunden, so dass durch eine Rauf- und Runterbewegung des Verbindungsmittels 18 das Schleifmittel 14, 15 in seinem Winkel verändert wird. Die Veränderung des Winkels µ des Schleifmittels 14, 15, wird durch die Kurvenscheibe 11 vorgegeben, die sich synchron mit dem Schneidmesser 10 dreht. Dadurch ist es möglich, die Schneidfläche mit unterschiedlichen Schneidenwinkeln zu versehen. FIG. 4 shows a Schneidmesserschleifvorrichtung. The cutting blade 10 is rotatably provided on a rotating shaft on which a cam 11 is arranged rotatably. The cutting surface 3 of the cutting blade 10 is ground by means of an abrasive 14, here a rotating grinding wheel 14, which abuts against the cutting surface 3 of the cutting blade. This grinding wheel 14 is pressed by means of a spring means 16 against a stop 17 and is adjustable in their angle μ relative to the horizontal. This adjustment is effected by means of a cam 13, here a roller 13, which is mounted longitudinally displaceable in a sliding bearing 12, so that the lever 21, which is connected to the roller 13, can perform the movement indicated by the double arrow. This lever 21 is connected by means of a connecting means 18 with the abrasive 14, 15, so that by an up and down movement of the connecting means 18, the abrasive 14, 15 is changed in its angle. The change in the angle μ of the abrasive 14, 15, is determined by the cam 11, which rotates synchronously with the cutting blade 10. This makes it possible to provide the cutting surface with different cutting angles.
