The invention relates to a device for cutting and / or rasping food in cubes, slices or strips, with at least one magazine for the food to be cut, a cutting device and a cross-cutting knife being provided in the feed direction of the food one behind the other The preamble of claim 1 defined in more detail.
Beispiele für solche Vorrichtungen zum Schneiden und/oder Raspeln von Lebensmitteln mit ei nem Querschneidemesser sind in der DE 200 1 1 472 U1 oder der DE 297 20 191 U1 beschrie ben. Examples of such devices for cutting and / or rasping food with egg nem cross-cutting knife are described in DE 200 1 1 472 U1 or DE 297 20 191 U1.
Die GB 1 208 123 A beschreibt eine Vorrichtung zum Schneiden von Lebensmitteln mit mehre ren, in der Art eines Rotors angeordneten Schneidmessern. Durch auf den Messern gelagerte Bolzen kann die mit den Schneidmessern erzeugte Schneiddicke eingestellt werden. GB 1 208 123 A describes a device for cutting foodstuffs with several cutting knives arranged in the manner of a rotor. The cutting thickness generated with the cutting knives can be adjusted by means of bolts mounted on the knives.
Die US 1 ,501 ,810 A beschreibt eine Schneidvorrichtung für Lebensmittel, dessen Schneidmes ser einen Abschnitt aufweist, dessen Neigung verstellt werden kann, um die Dicke der geschnit tenen Scheiben zu verändern. Hierzu wird ein in entsprechenden Muttergewinden gelagerter Schraubbolzen verdreht. The US 1, 501, 810 A describes a cutting device for food, the Schneidmes water has a section whose inclination can be adjusted to change the thickness of the sliced slices. For this purpose, a screw bolt mounted in corresponding nut threads is turned.
Aus der US 1 ,341 ,894 A ist eine weitere Schneidvorrichtung für Lebensmittel bekannt, das mehrere in der Form eines Rotors angeordnete Schneidmesser aufweist. Zusätzlich ist ein ring förmiges Schneidelement vorgesehen, das mittels mehrerer Verbindungsstangen stabilisiert ist. A further cutting device for foodstuffs is known from US Pat. No. 1,341,894 A, which has several cutting blades arranged in the form of a rotor. In addition, a ring-shaped cutting element is provided, which is stabilized by means of several connecting rods.
Vorrichtungen zur Beeinflussung der Planheit des Querschneidemessers sind aus dem allge meinen Stand der Technik bekannt. Da diese Querschneidemesser das zu schneidende Le bensmittel unmittelbar nach dessen Austritt aus einem Raum, in dem es in einer entsprechen den Maschine aufgenommen ist, abschneiden, ist es zum Erreichen der bestmöglichen Schnei dergebnisse erforderlich, dass das Querschneidemesser sehr exakt entlang der äußeren Be grenzung dieses Raums, die mit dem Querschneidemesser zusammenwirkt, um das Lebens mittel abzuscheren, entlang geführt wird. Devices for influencing the flatness of the cross-cutting knife are known from the general my prior art. Since this cross-cutting knife cut the food to be cut immediately after it leaves a room in which it is accommodated in a corresponding machine, it is necessary to achieve the best possible cutting results that the cross-cutting knife very precisely along the outer boundary of this Space that interacts with the cross cutter to shear off the food is guided along.
Da eine exakte Planheit des Querschneidemessers nicht gewährleistet werden kann, wird ge mäß dem allgemeinen Stand der Technik auf unterschiedliche Arten versucht, das Querschnei- demesser so zu biegen, dass es möglichst exakt an der genannten, eine Schneidkante bilden den äußeren Begrenzung anliegt. Zum einen ist die Einstellung des Querschneidemessers mit den bekannten Mitteln jedoch recht schwierig, insbesondere wenn es sich um mehrflügelige Querschneidemesser handelt, und es können sich zum anderen bei dieser Verstellung Spalte und ähnliche Freiräume auf der Oberfläche des Querschneidemessers ergeben, was zu hygie nischen Problemen führen kann. Since an exact flatness of the cross-cutting knife cannot be guaranteed, attempts are made in different ways according to the general state of the art to to bend the knife in such a way that it rests as precisely as possible on the mentioned, a cutting edge forming the outer boundary. On the one hand, the setting of the cross-cutting knife with the known means is quite difficult, especially when it comes to multi-wing cross-cutting knife, and on the other hand, this adjustment can result in gaps and similar free spaces on the surface of the cross-cutting knife, which lead to hygienic problems can.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Schneiden und/oder Raspeln von Lebensmitteln in Würfel-, Scheiben- oder Streifenform mit einem Querschneide messer zu schaffen, dessen Planheit auf einfache Weise beeinflusst werden kann. It is therefore the object of the present invention to provide a device for cutting and / or rasping food in cubes, slices or strips with a cross-cutting knife, the flatness of which can be influenced in a simple manner.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst. According to the invention, this object is achieved by the features mentioned in claim 1.
Gemäß der vorliegenden Erfindung steht das wenigstens eine, auf das Querschneidemesser wirkende Stellelement über eine Stange mit einem Lagerungselement in Wirkverbindung und die Stange kann so eingestellt werden, dass mit derselben der Abstand zwischen dem Stel lelement und dem Lagerungselement verändert werden kann. Dadurch kann eine von dem Stellelement auf das Querschneidemesser wirkende Kraft erzeugt und zum Biegen des Quer schneidemessers so beeinflusst werden, dass dessen Planheit verändert und es relativ zu der Kante, mit dem das Querschneidemesser zusammenwirkt, eingestellt werden. According to the present invention, the at least one adjusting element acting on the cross-cutting knife is operatively connected to a mounting element via a rod and the rod can be adjusted so that the distance between the adjusting element and the mounting element can be changed with the same. As a result, a force acting on the cross-cutting knife by the actuating element can be generated and influenced for bending the cross-cutting knife in such a way that its flatness is changed and it can be adjusted relative to the edge with which the cross-cutting knife interacts.
Dabei ist die erfindungsgemäße Lösung nicht nur sehr einfach zu realisieren, sondern sie ver meidet die bei bekannten Querschneidemessern vorhandenen Hygieneprobleme, da das Stel lelement über das Versteifungselement auf den Klingenabschnitt des Querschneidemessers wirkt, sodass zwischen dem Versteifungselement und dem Klingenabschnitt die Bildung eines Spalts vermieden wird und sich zum einen an der erfindungsgemäßen Vorrichtung keine Parti kel und andere Verschmutzungen absetzen können und dieselbe zum anderen sehr einfach ge reinigt werden kann. The solution according to the invention is not only very easy to implement, but also avoids the hygiene problems that exist with known cross-cutting knives, since the actuating element acts on the blade section of the cross-cutting knife via the stiffening element, so that the formation of a gap between the stiffening element and the blade section is avoided and on the one hand no Parti angle and other dirt can settle on the device according to the invention and the same can be cleaned very easily on the other hand.
Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung besteht darin, dass die Stange als Griff zum Tragen des Querschneidemessers verwendet werden kann. Another advantage of the device according to the invention is that the rod can be used as a handle for carrying the cross-cutting knife.
In einer sehr vorteilhaften Weiterbildung der Erfindung kann vorgesehen sein, dass die Stange mittels einer Gewindeverbindung an dem Stellelement und/oder dem Lagerungselement gehal ten ist. Auf diese Weise ist eine sehr einfache Verstellung der Stange möglich. Die Bedienung der Stange und damit das Einstellen der Planheit des Querschneidemessers kann noch weiter vereinfacht werden, wenn die Stange an dem Stellelement und/oder an dem Lagerungselement drehbar gelagert ist. In a very advantageous development of the invention it can be provided that the rod is held on the adjusting element and / or the bearing element by means of a threaded connection. In this way, a very simple adjustment of the rod is possible. The operation of the rod and thus the adjustment of the flatness of the cross-cutting knife can be simplified even further if the rod is rotatably mounted on the adjusting element and / or on the bearing element.
Wenn dabei die Stange mittels einer Gewindeverbindung an dem Stell When doing the rod by means of a threaded connection to the Stell
element gehalten und in einer Vertiefung des Lagerungselements drehbar gelagert ist, so ergibt sich eine Lösung, die von einem Nutzer besonders einfach bedient werden kann. element is held and rotatably mounted in a recess of the storage element, this results in a solution that can be operated particularly easily by a user.
Alternativ dazu kann auch vorgesehen sein, dass die Stange zweiteilig mit zwei Stangenab schnitten ausgebildet ist und eine Verstelleinrichtung zum Verstellen der Länge der Stange aufweist. Auch auf diese Weise lässt sich der Abstand zwischen dem Stellelement und dem Lagerungselement verändern. Alternatively, it can also be provided that the rod is designed in two parts with two Stangenab cuts and has an adjusting device for adjusting the length of the rod. The distance between the adjusting element and the mounting element can also be changed in this way.
Wenn dabei die Verstelleinrichtung über jeweilige Gewindeverbindungen mit den beiden Stan genabschnitten verbunden ist, so ist eine besonders einfache Verstellung der beiden Stangen abschnitte gegeben. If the adjusting device is connected via respective threaded connections with the two Stan gene sections, a particularly simple adjustment of the two rod sections is given.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass das Lagerungselement auf einer Antriebswelle des Querschneidemessers angebracht ist. Dies stellt eine einfache Möglichkeit zur Unterbringung des Lagerungselements dar. In a further advantageous embodiment of the invention it can be provided that the bearing element is attached to a drive shaft of the cross-cutting knife. This is a simple way of accommodating the storage element.
Eine Verbesserung des Schneidergebnisses lässt sich erreichen, wenn der Klingenabschnitt mehrere Schneidflügel aufweist, wobei sich das Versteifungselement über jeden der Schneid flügel erstreckt, und wobei für jeden der Schneidflügel ein jeweiliges, auf das Versteifungsele ment wirkendes Stellelement vorgesehen ist, das mit einer jeweiligen Stange mit dem Lage rungselement in Wirkverbindung steht. The cutting result can be improved if the blade section has a plurality of cutting wings, the stiffening element extending over each of the cutting wings, and with a respective adjusting element acting on the stiffening element being provided for each of the cutting wings, which is provided with a respective rod the storage element is in operative connection.

Eine derartige Vorrichtung zum Schneiden und/oder Raspeln von Lebensmitteln in Würfel-, Scheiben- oder Streifenform ist zum Beispiel in der DE 297 20 191 U1 beschrieben, weshalb hierin auf eine detaillierte Darstellung und Be schreibung derselben verzichtet wird. Fig. 1 shows a transverse cutting knife 1, which has several devices 2 for influencing the flatness of the same. The cross-cutting knife 1 is itself part of a device, not shown in the figures, for cutting and / or rasping food in the form of cubes, slices or strips, in which in a feed direction of the food behind one another the at least one magazine for the food to be cut, a cutting device and the transverse cutter 1 are provided. Such a device for cutting and / or rasping food in the form of cubes, slices or strips is described, for example, in DE 297 20 191 U1, which is why a detailed illustration and description of the same is dispensed with here.
In Fig. 2 ist ein Schnitt durch das Querschneidemesser 1 sowie eine der Vorrichtungen 2 zur Beeinflussung der Planheit desselben dargestellt. Das Querschneidemesser 1 wird insbeson dere zum Schneiden von Lebensmitteln, wie zum Beispiel Fleisch, eingesetzt und wirkt mit ei ner Schneideeinrichtung, wie zum Beispiel einem nicht dargestellten Schneidgatter, zusammen, indem es entlang des Schneidgatters geführt wird und dabei aus dem Schneidgatter austreten des Fleisch durch Abscheren schneidet. Das Zusammenwirken des Querschneidemessers 1 mit dem Schneidgatter ist beispielsweise in der DE 297 20 191 U1 oder der DE 200 1 1 472 LH beschrieben. FIG. 2 shows a section through the cross-cutting knife 1 and one of the devices 2 for influencing the flatness of the same. The cross-cutting knife 1 is used in particular for cutting food, such as meat, and interacts with egg ner cutting device, such as a cutting gate, not shown, by being guided along the cutting gate and the meat emerge from the cutting gate Shearing cuts. The interaction of the cross-cutting knife 1 with the cutting gate is described, for example, in DE 297 20 191 U1 or DE 200 1 1 472 LH.
Um das Querschneidemesser 1 so gut wie möglich an das Schneidgatter oder an eine entspre chende Schneideinrichtung, mit der das Querschneidemesser zusammenarbeitet, anzulegen, dient die wenigstens eine Vorrichtung 2, die nachfolgend ausführlich beschrieben wird. In order to apply the cross-cutting knife 1 as well as possible to the cutting gate or to a corresponding cutting device with which the cross-cutting knife works, the at least one device 2, which is described in detail below, is used.
Das Querschneidemesser 1 weist einen Klingenabschnitt 3 und ein mit dem Klingenabschnitt 3 auf an sich bekannte Weise verbundenes Versteifungselement 4 zur Versteifung des Klingen abschnitts 3 auf. Im vorliegenden Fall handelt es sich bei dem Querschneidemesser 1 um ein vierflügeliges Querschneidemesser, d. h. der Klingenabschnitt 3 weist insgesamt vier Schneid flügel 5 auf. Mittels der Vorrichtungen 2 kann im vorliegenden Fall jeder der Schneidflügel 5 des Klingenabschnitts 3 einzeln verstellt werden. Die Vorrichtung 2 dient somit zur Beeinflussung der Planheit des Klingenabschnitts 3 des Querschneidemessers 1. In nicht dargestellter Weise könnte das Querschneidemesser 1 auch als Scheibenmesser ausgebildet sein. Selbstverständlich könnte das Querschneidemesser 1 auch eine andere Anzahl an Schneidflü gel 5 aufweisen, insbesondere auch eine geringere Anzahl. Vorzugsweise wäre dabei jeder der Schneidflügel 5 mit einer separaten Vorrichtung 2 zur Beeinflussung der Planheit des jeweiligen Schneidflügels 5 und somit des gesamten Klingenabschnitts 3 des Querschneidemessers 1 versehen. The cross-cutting knife 1 has a blade section 3 and a stiffening element 4, which is connected to the blade section 3 in a manner known per se, for stiffening the blade section 3. In the present case, the cross-cutting knife 1 is a four-wing cross-cutting knife, ie the blade section 3 has a total of four cutting wings 5. By means of the devices 2, each of the cutting wings 5 of the blade section 3 can be adjusted individually in the present case. The device 2 thus serves to influence the flatness of the blade section 3 of the cross-cutting knife 1. In a manner not shown, the cross-cutting knife 1 could also be designed as a circular knife. Of course, the cross-cutting knife 1 could also have a different number of cutting blades 5, in particular also a smaller number. Preferably, each of the cutting blades 5 would be provided with a separate device 2 for influencing the flatness of the respective cutting blade 5 and thus the entire blade section 3 of the cross-cutting knife 1.
Die Vorrichtungen 2 sind im vorliegenden Fall identisch zueinander ausgebildet und es wird nachfolgend unter Bezugnahme auf Fig. 2 eine der Vorrichtungen 2 beschrieben. Die Vorrich tung 2 weist ein mit dem Versteifungselement 4 verbundenes bzw. allgemein ausgedrückt ein auf das Versteifungselement 4 wirkendes Stellelement 6, ein auf einer nicht dargestellten An triebswelle des Querschneidemessers 1 angebrachtes, im vorliegenden Fall in Form einer Buchse ausgeführtes Lagerungselement 7 und eine das Stellelement 6 mit dem Lagerungs element 7 verbindende Stange 8 auf. Wie nachfolgend beschrieben kann mittels der Stange 8 der Abstand zwischen dem Stellelement 6 und dem Lagerungselement 7 verändert werden. Wenn dabei der Abstand vergrößert wird, wird eine Kraft auf das Stellelement 6 aufgebracht bzw. dieselbe wird erhöht, was zu einem Biegemoment bzw. zu einer Erhöhung des Biegemo ments auf den jeweiligen Schneidflügel 5 des Querschneidemessers 1 führt und somit eine Veränderung der Planheit des Querschneidemessers 1 bzw. des Klingenabschnitts 3 dessel ben bewirkt. Selbstverständlich kann der Abstand zwischen dem Stellelement 6 und dem Lage rungselement 7 auch verkürzt werden, um die auf das Querschneidemesser 1 wirkende Kraft zu verringern. In the present case, the devices 2 are identical to one another and one of the devices 2 is described below with reference to FIG. 2. The Vorrich device 2 has a connected to the stiffening element 4 or, in general terms, an actuating element 6 acting on the stiffening element 4, a mounting element 7 mounted on a drive shaft (not shown) of the cross-cutting knife 1, in the present case in the form of a bushing, and an adjusting element 6 with the storage element 7 connecting rod 8. As described below, the distance between the adjusting element 6 and the mounting element 7 can be changed by means of the rod 8. If the distance is increased, a force is applied to the adjusting element 6 or the same is increased, which leads to a bending moment or an increase in the Biegemo element on the respective cutting blade 5 of the cross-cutting knife 1 and thus a change in the flatness of the cross-cutting knife 1 or the blade section 3 causes the same ben. Of course, the distance between the adjusting element 6 and the location element 7 can also be shortened in order to reduce the force acting on the cross-cutting knife 1.
In dem in Fig. 2 dargestellten Ausführungsbeispiel ist die Stange 8 mittels einer Gewindever bindung 9 an dem Stellelement 6 gehalten. Hierzu weist das Stellelement 6 im vorliegenden Fall eine Durchgangsbohrung 10 auf, durch welche die Stange 8 verläuft. Am Ende der Stange 8 ist dieselbe mittels einer Mutter 1 1 gehalten, die zusammen mit einem nicht dargestellten Au ßengewinde der Stange 8 die Gewindeverbindung 9 bildet. Selbstverständlich könnte die Durchgangsbohrung 10 auch mit einem Innengewinde versehen sein, das zusammen mit dem Außengewinde der Stange 8 die Gewindeverbindung 9 bilden könnte. Auf der gegenüberlie genden Seite ist die Stange 8 in einer Vertiefung 12 des Lagerungselements 7 drehbar gela gert. Durch Verdrehen der Stange 8 kann dieselbe tiefer in das Stellelement 6 ein- oder aus demselben herausgeschraubt werden. Zur Vereinfachung des Verdrehens der Stange 8 weist diese zwei einander gegenüberliegende Abflachungen 13 auf, an die zum Beispiel ein Schrau benschlüssel oder ähnliches angesetzt werden kann. In den Figuren ist an den Stangen 8 je weils nur eine der Abflachungen 13 zu erkennen. Die Stange 8 könnte auch fest mit dem Lagerungselement 7 verbunden sein, wobei sich durch die dargestellte Lösung ein großer Verstellbereich ergibt. Des Weiteren könnte sich die Durch gangsbohrung 10 bzw. in diesem Fall eine Sackloch-Gewindebohrung auch in dem Lagerungs- element 7 befinden und die Stange 8 könnte an dem Stellelement 6 drehbar gelagert oder fest mit demselben verbunden sein. In the exemplary embodiment shown in FIG. 2, the rod 8 is held on the adjusting element 6 by means of a threaded connection 9. For this purpose, the adjusting element 6 in the present case has a through hole 10 through which the rod 8 runs. At the end of the rod 8 the same is held by means of a nut 11, which together with a non-illustrated outer thread of the rod 8 forms the threaded connection 9. Of course, the through hole 10 could also be provided with an internal thread which, together with the external thread of the rod 8, could form the threaded connection 9. On the opposite side, the rod 8 is rotatably Gela Gert in a recess 12 of the bearing element 7. By rotating the rod 8, the same can be screwed deeper into or out of the adjusting element 6. To simplify the rotation of the rod 8, it has two opposing flats 13 to which, for example, a screw wrench or the like can be attached. In the figures, only one of the flat areas 13 can be seen on the rods 8. The rod 8 could also be firmly connected to the bearing element 7, the solution shown resulting in a large adjustment range. Furthermore, the through-hole 10 or, in this case, a tapped blind hole could also be located in the mounting element 7 and the rod 8 could be rotatably mounted on the adjusting element 6 or firmly connected to it.
In nicht dargestellter Weise könnte die Stange 8 auch zweiteilig mit zwei in Verlängerung zuei nander angeordneten Stangenabschnitten ausgebildet sein und eine Verstelleinrichtung zum Verstellen der Länge der Stange aufweisen. Eine solche Verstelleinrichtung könnte zum Bei spiel in Form einer Hülse ausgebildet sein, die über jeweilige Gewindeverbindungen mit den beiden Stangenabschnitten verbunden sein könnte. In a manner not shown, the rod 8 could also be designed in two parts with two rod sections arranged in extension to one another and have an adjusting device for adjusting the length of the rod. Such an adjusting device could, for example, be designed in the form of a sleeve which could be connected to the two rod sections via respective threaded connections.
Um die Kraft auf das Querschneidemesser 1 verändern zu können, wäre es grundsätzlich auch möglich, mehrere Stangen 8 mit unterschiedlichen Längen vorzuhalten und je nach erforderli cher Biegung des Querschneidemessers 1 die Stange 8 mit der gewünschten Länge einzuset zen. Eine weitere Möglichkeit könnte darin bestehen, Distanzelemente einzusetzen, um die wirksame Länge der Stange 8 zu verändern. Solche Distanzelemente könnten in entsprechen de Vertiefungen des Stellelements 6 und/oder des Lagerungselements 7, in denen die Stange 8 angeordnet wäre, eingesetzt werden. In order to be able to change the force on the cross-cutting knife 1, it would in principle also be possible to hold several rods 8 with different lengths and, depending on the required bend of the cross-cutting knife 1, insert the rod 8 with the desired length. Another possibility could be to use spacer elements in order to change the effective length of the rod 8. Such spacer elements could be used in corresponding de depressions of the adjusting element 6 and / or of the bearing element 7, in which the rod 8 would be arranged.
