Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Aufschneiden von Lebensmittelprodukten, insbesondere einen Hochleistungs-Slicer, mit einer Produktzuführung, wenigstens einem Schneidmesser, das um eine Messerachse rotiert und/oder um eine Mittelachse umläuft und dem wenigstens ein aufzuschneidendes Produkt in einer Produktzuführrichtung zuführbar ist, und einer Messerhalterung, an der das Schneidmesser anbringbar ist.The present invention relates to a device for slicing food products, in particular a high-performance slicer, with a product feed, at least one cutting blade which rotates about a knife axis and / or rotates about a central axis and at least one product to be cut in a product feed direction can be fed, and a knife holder to which the cutting blade is attachable.

Derartige Vorrichtungen sind grundsätzlich bekannt und dienen dazu, Lebensmittelprodukte wie beispielsweise Wurst, Fleisch und Käse mit hoher Geschwindigkeit in Scheiben zu schneiden. Typische Schnittgeschwindigkeiten liegen zwischen mehreren 100 bis einigen 1.000 Schnitten pro Minute. Moderne Hochleistungs-Slicer unterscheiden sich unter anderem in der Ausgestaltung des Schneidmessers sowie in der Art und Weise des Rotationsantriebs für das Schneidmesser. So genannte Sichel-oder Spiralmesser rotieren um eine hier auch als Messerachse bezeichnete Rotationsachse, wobei diese Rotationsachse selbst keine zusätzliche Bewegung ausführt, wobei dies aber nicht zwingend ist, d.h. alternativ kann die Rotationsachse selbst eine wie auch immer geartete zusätzliche Bewegung ausführen. Bei Slicern mit Kreismessern ist dagegen vorgesehen, das rotierende Kreismesser zusätzlich um eine von der Rotationsachse beabstandete weitere Achse (hier auch Mittelachse genannt) planetarisch umlaufen zu lassen. Welchem Messertyp bzw. welcher Antriebsart der Vorzug zu geben ist, ist von der jeweiligen Anwendung abhängig. Generell lässt sich sagen, dass mit lediglich rotierenden Sichelmessern höhere Schnittgeschwindigkeiten erzielt werden können, wohingegen rotierende und zusätzlich planetarisch umlaufende Kreismesser ohne Einbußen bei der Schneidqualität universeller einsetzbar sind.Such devices are basically known and serve to slice food products such as sausage, meat and cheese at high speed. Typical cutting speeds are between several hundred to several thousand cuts per minute. Modern high-performance slicers differ, inter alia, in the design of the cutting blade and in the manner of the rotary drive for the cutting blade. So-called sickle or spiral blades rotate about an axis of rotation, also referred to herein as a knife axis, this rotation axis itself does not perform any additional movement, but this is not mandatory, ie alternatively, the axis of rotation itself perform any additional movement. For slicers with circular knives, on the other hand, it is provided that the rotating circular knife is also circulated in a planetary manner around a further axis spaced apart from the axis of rotation (also referred to here as center axis). Which blade type or type of drive is to be preferred depends on the respective application. Generally leaves say that with only rotating sickle knives higher cutting speeds can be achieved, whereas rotating and additionally planetary circular blades are universally applicable without sacrificing the cutting quality.

Die vorstehend erwähnten hohen Schnittgeschwindigkeiten machen es - und dies gilt unabhängig vom Messertyp und von der Antriebsart - erforderlich, dass in bestimmten Betriebssituationen, insbesondere bei einem portionsweisen Aufschneiden von Produkten, so genannte Leerschnitte durchgeführt werden, in denen sich das Messer weiterhin bewegt, d.h. seine Schneidbewegung ausführt, dabei jedoch nicht in das Produkt, sondern "ins Leere" schneidet, damit vorübergehend keine Scheiben vom Produkt abgetrennt werden und diese "Schneidpausen" dazu genutzt werden können, eine mit den zuvor abgetrennten Scheiben gebildete Portion, beispielsweise einen Scheibenstapel oder geschindelt angeordnete Scheiben, abzutransportieren. Die zwischen zwei aufeinanderfolgend abgetrennten Scheiben verstreichende Zeit reicht ab einer bestimmten Schneidleistung bzw. Schnittgeschwindigkeit für einen ordnungsgemäßen Abtransport der Scheibenportionen nicht aus. Die Länge dieser "Schneidpausen" und die Anzahl der Leerschnitte pro "Schneidpause" sind von der jeweiligen Anwendung abhängig.The above-mentioned high cutting speeds make it necessary - and this applies regardless of the type of knife and the type of drive - that in certain operating situations, in particular with a portionwise slicing of products, so-called idle cuts are carried out, in which the knife continues to move, i. performs his cutting motion, but not in the product, but "in the void" cuts, so temporarily no slices are separated from the product and these "cutting breaks" can be used to a formed with the previously separated slices portion, such as a stack of discs or shingles arranged discs to be transported away. The time passing between two consecutively separated slices does not suffice for a proper cutting performance or cutting speed for a proper removal of the slice portions. The length of these "cutting breaks" and the number of idle cuts per "cutting break" depend on the particular application.

Ein in der Praxis bekanntes Problem in Verbindung mit der Durchführung von Leerschnitten besteht darin, dass es in den meisten Fällen nicht genügt, einfach die Zufuhr des Produktes vorübergehend anzuhalten, um das Abtrennen von Scheiben zu verhindern. Bei Produkten mit weicher Konsistenz kommt es nämlich regelmäßig vor, dass sich nach dem Anhalten des Produktvorschubs Entspannungseffekte einstellen, wodurch das vordere Produktende über die Schneidebene hinaus und damit in den Wirkungsbereich des Schneidmessers gelangt. Die Folge ist ein unerwünschtes Abtrennen so genannter Produktschnipsel oder Produktschnitzel. Abgesehen davon kommt es zu einer solchen Schnitzelbildung unabhängig von der Produktkonsistenz zwangsläufig immer dann, wenn die Produkte während des Aufschneidebetriebs kontinuierlich zugeführt werden, d.h. auch bei Produkten mit fester Konsistenz, bei denen also die vorstehend erwähnten Entspannungseffekte nicht auftreten, kommt es bei einer kontinuierlichen Produktzufuhr zu einer Schnitzelbildung.A problem known in practice in connection with the performance of blanks is that, in most cases, it is not enough to simply stop the supply of the product temporarily to prevent the separation of slices. In fact, in the case of products with a soft consistency, it regularly happens that relaxation effects occur after the product feed has stopped, as a result of which the front end of the product passes beyond the cutting plane and thus into the effective range of the cutting blade. The consequence is an undesirable one Separating so-called product chips or product chips. Apart from that, it always comes to such a Schnitzelbildung regardless of the product consistency whenever the products are continuously fed during the slicing operation, ie even with products with a firm consistency, so where the above-mentioned relaxation effects do not occur, it comes with a continuous product supply to a schnitzel formation.

Die vorstehend beschriebenen Phänomene sind dem Fachmann hinreichend bekannt, weshalb hierauf nicht näher eingegangen wird.The phenomena described above are well known to the person skilled in the art, which is why this will not be discussed in detail.

Aus dem Stand der Technik sind bereits MaĂźnahmen bekannt, die dazu dienen, eine Schnitzelbildung bei der DurchfĂĽhrung von Leerschnitten zu vermeiden. Hierzu wird beispielsweise auf EP 0 289 765 A1 , DE 42 14 264 A1 , EP 1 046 476 A2 , DE 101 147 348 A1 , DE 154 952 , DE 10 2006 043 697 A1 und DE 103 33 661 A1 verwiesen.Measures are already known from the prior art, which serve to avoid a Schnitzelbildung when performing blanks. For this example, on EP 0 289 765 A1 . DE 42 14 264 A1 . EP 1 046 476 A2 . DE 101 147 348 A1 . DE 154 952 . DE 10 2006 043 697 A1 and DE 103 33 661 A1 directed.

Demnach wurde bereits vorgeschlagen, für die Durchführung von Leerschnitten die Produktzufuhr nicht nur zu unterbrechen, sondern zusätzlich das Produkt - gegebenenfalls samt Produktauflage - zurückzuziehen. Dieser Ansatz stößt insbesondere dann an Grenzen, wenn die Schnittgeschwindigkeiten und/oder die dabei zu bewegenden Massen zu groß werden, da dann nicht mehr sichergestellt werden kann, dass das vordere Produktende ausreichend schnell zurückgezogen werden kann. Als Alternative zum Zurückziehen des Produkts wurde ferner bereits vorgeschlagen, das Schneidmesser vom vorderen Produktende wegzubewegen. Beide Lösungsansätze haben zur Folge, dass zwischen dem vorderen Produktende und dem Schneidmesser ein ausreichend großer Abstand hergestellt wird, der eine Schnitzelbildung sicher verhindert. Der erforderliche Messerhub beträgt lediglich einige Millimeter, muss allerdings in einer sehr kurzen Zeit in der Größenordnung von einigen Hundertstel Sekunden erfolgen. Die Möglichkeit einer Messerverstellung kann auch für weitere Zusatzfunktionen genutzt werden, z.B. für das Einstellen des Schneidspalts oder für Leerschnitte im Rahmen einer Höheneinstellung bzw. Einstellung der Eintauchtiefe des Schneidmessers, die insbesondere in Bezug auf das oder die aufzuschneidenden Produkte bzw. die Produktauflage erfolgt, worauf nachstehend näher eingegangen wird.Accordingly, it has already been proposed not only to interrupt the product supply for the performance of blanks, but also to withdraw the product, if appropriate together with the product support. This approach reaches its limits, in particular, when the cutting speeds and / or the masses to be moved become too large, because then it can no longer be ensured that the front end of the product can be withdrawn sufficiently quickly. As an alternative to retracting the product, it has also been proposed to move the cutting blade away from the front end of the product. Both solutions have the consequence that between the front end of the product and the cutting blade a sufficiently large distance is produced, which reliably prevents a Schnitzelbildung. The required blade stroke is only a few millimeters, but must be in a very short time on the order of a few hundredths of a second. The possibility of a knife adjustment can also be used for other additional functions, eg for adjusting the cutting gap or for idle cuts in the context of a height adjustment or adjustment of the insertion depth of the cutting blade, which takes place in particular in relation to the or products to be sliced or the product edition, where will be discussed in more detail below.

Der Stand der Technik schlägt verschiedene Möglichkeiten vor, den gewünschten Abstand zwischen Messer und Produkt durch eine Verlagerung des Messers herzustellen.The prior art proposes various ways to produce the desired distance between knife and product by a displacement of the knife.

Eine Möglichkeit, die beispielsweise in DE 101 47 348 A1 beschrieben ist, besteht darin, lediglich die rotierende Messerhalterung, an der das Messer auswechselbar angebracht ist und die auch als Messeraufnahme, Messerwelle oder Rotor bezeichnet wird, zu bewegen, und zwar relativ zu den übrigen Bestandteilen des so genannten Messerkopfes, der zusätzlich zu der erwähnten Messerhalterung insbesondere eine Drehlagerung für die Rotationsbewegung des Messers bzw. der Messerhalterung sowie ein Basisteil umfasst, mit dem der Messerkopf und damit die Messerhalterung an einem Gestell oder Rahmen des Slicers befestigt wird. Diese Befestigung kann beispielsweise an oder in einem so genannten Schneidkopfgehäuse erfolgen, an oder in welchem nicht nur der Messerkopf samt Messer, sondern außerdem der Antriebsmotor für den mit dem Messerkopf z.B. über einen Antriebsriemen zusammenwirkenden Messer-Rotationsantrieb angebracht sind.One way, for example, in DE 101 47 348 A1 is described, to move only the rotating knife holder on which the knife is interchangeably mounted and which is also referred to as a knife holder, knife shaft or rotor, relative to the other components of the so-called cutter head, in addition to the mentioned Knife holder in particular comprises a rotary bearing for the rotational movement of the knife or the knife holder and a base part, with which the cutter head and thus the knife holder is attached to a frame or frame of the slicer. This attachment can be done for example on or in a so-called cutting head housing on or in which not only the cutter head and knife, but also the drive motor for the cooperating with the cutter head, for example via a drive belt knife rotary drive are mounted.

Es ist auch möglich, den Messerkopf als Ganzes zu verlagern, so dass zum Verstellen des Messers eine Relativbewegung zwischen Messerhalterung und Drehlagerung des Messers nicht erforderlich ist. Eine derartige Lösung ist beispielsweise in DE 10 2006 043 697 A1 gezeigt.It is also possible to displace the cutter head as a whole, so that for adjusting the knife, a relative movement between knife holder and pivot bearing of the knife is not required. Such a solution is for example in DE 10 2006 043 697 A1 shown.

Des Weiteren ist es möglich, das gesamte Schneidkopfgehäuse samt Messerkopf und Rotationsantrieb zu bewegen. Lösungen dieser Art sind beispielsweise in EP 1 046 476 A2 beschrieben.Furthermore, it is possible to move the entire cutterhead housing including cutter head and rotary drive. Solutions of this type are for example in EP 1 046 476 A2 described.

Diese vorstehend erläuterten Lösungsansätze unterscheiden sich nicht nur hinsichtlich der Größe der zu bewegenden Masse, sondern auch hinsichtlich des Konstruktionsaufwandes sowie der Anwendbarkeit für unterschiedliche Messer- bzw. Antriebsarten. Eine Bewegung lediglich der Messerhalterung beispielsweise hat zwar den Vorteil einer relativ geringen zu bewegenden Masse, bedeutet aber einen relativ hohen konstruktiven Aufwand, da mit dem Messer ein Gegenstand entlang einer Achse verschoben oder auf andere Art und Weise bewegt werden muss, der gleichzeitig mit hoher Geschwindigkeit, z.B. um eben die genannte Achse, rotiert. Hierfür sind Probleme in Verbindung mit der Lagerung des Messers bzw. der Messerhalterung zu lösen. Während die vorstehend erwähnten Sichel- oder Spiralmesser lediglich um eine Achse rotieren, diese Achse aber nicht zusätzlich eine Umlaufbewegung ausführt, lassen sich Konzepte zum Verstellen des Messers trotz der erwähnten Lagerungsproblematik mit vertretbarem Aufwand realisieren. Anders ist dies bei Slicern mit rotierenden und gleichzeitig planetarisch umlaufenden Kreismessern, denn hier besteht das Problem, mit vertretbarem konstruktiven Aufwand eine Verlagerung nur des Messers bzw. der Messerhalterung zu bewerkstelligen.These approaches described above differ not only in terms of the size of the mass to be moved, but also in terms of design effort and applicability for different types of knives or drives. Although a movement of only the knife holder, for example, has the advantage of a relatively low mass to be moved, but means a relatively high design effort, since with the knife an object must be moved along an axis or moved in any other way, the same time at high speed , eg about the same axis, rotates. For this problems in connection with the storage of the knife or the knife holder to solve. While the above-mentioned sickle or spiral blades only rotate about one axis, but this axis does not additionally carry out a circulation movement, concepts for adjusting the blade despite the aforementioned storage problems can be realized with reasonable effort. This is different with slicers with rotating and at the same time planetary revolving circular knives, because here there is the problem to accomplish with reasonable design effort a displacement of only the knife or the knife holder.

Unabhängig von den konstruktiven Problemen hinsichtlich der Lagerung des Messers bzw. der Messerhalterung kann bei den bekannten Lösungsansätzen die erreichbare Verstellgeschwindigkeit aufgrund der zu bewegenden Massen zu gering sein, um bei hohen Schnittgeschwindigkeiten ohne Qualitätseinbußen Leerschnitte durchzuführen.Regardless of the design problems with respect to the storage of the knife or the knife holder can be achieved in the known approaches to the achievable adjustment speed due to the Masses are too low to perform at high cutting speeds without sacrificing quality idle cuts.

Aufgabe der Erfindung ist es daher, bei einer Schneidvorrichtung der vorstehend genannten Art die Leistungsfähigkeit hinsichtlich einer zum Bereitstellen von Zusatzfunktionen vorgesehenen Messerverstellung zu verbessern und insbesondere eine zuverlässigere Durchführung von Leerschnitten zu ermöglichen.The object of the invention is therefore to improve in a cutting device of the aforementioned type, the performance in terms of providing provided for additional functions knife adjustment and in particular to allow a more reliable implementation of blanks.

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

Erfindungsgemäß ist eine Verstelleinrichtung vorgesehen, die dazu ausgebildet ist, das Schneidmesser zu verformen. Anstatt das gesamte Schneidmesser einschließlich der Messerhalterung und/oder einem Messerkopf relativ zu dem Produkt zu bewegen, wird also lediglich die Form des Schneidmessers verändert. Durch die Verformung kann der Schneidenbereich des Schneidmessers zur Durchführung von Zusatzfunktionen wie Leerschnitten von dem Produkt zurückgezogen bzw. wegbewegt werden, ohne dass relativ schwere Bauteile in Bewegung versetzt werden müssen. Da also die beim Verstellen zu beschleunigende Masse verringert ist, kann das Verstellen des Messers besonders schnell erfolgen. Die Verformung kann bei Bedarf durch die Verstelleinrichtung herbeigeführt und ebenfalls bei Bedarf wieder aufgehoben werden. Durch dieses Prinzip, wonach das Verstellen des Schneidmessers durch eine Verformung desselben erfolgt, entfallen auch die konstruktiven Probleme in Verbindung mit der Drehlagerung der Messerhalterung, da weder die Messerhalterung noch die entsprechende Lagerkomponente an der Verstellbewegung beteiligt sind.According to the invention, an adjusting device is provided, which is designed to deform the cutting blade. Thus, rather than moving the entire cutting blade including the knife holder and / or a knife head relative to the product, only the shape of the cutting knife is changed. As a result of the deformation, the cutting area of the cutting blade can be withdrawn or moved away from the product for carrying out additional functions, such as blank cuts, without having to move relatively heavy components into motion. Since the mass to be accelerated during adjustment is thus reduced, the adjustment of the blade can be particularly rapid. If necessary, the deformation can be brought about by the adjusting device and can likewise be canceled again if necessary. By this principle, according to which the adjustment of the cutting blade by a deformation of the same, also eliminates the design problems in connection with the pivot bearing of the knife holder, since neither the knife holder nor the corresponding bearing component are involved in the adjustment.

Der Begriff "Messerhalterung" ist hier generell breit zu verstehen. Es handelt sich um ein Bauteil oder eine Baugruppe, an dem bzw. an der das Schneidmesser in einer wie auch immer gearteten Weise unmittelbar oder mittelbar gehaltert ist.The term "knife holder" is to be understood here broadly. It is a component or an assembly on which or on the Cutting knife is supported in a way whatsoever directly or indirectly.

Vorteilhafte Ausgestaltungen der Erfindung sind auch in den abhängigen Ansprüchen, der Beschreibung sowie der Zeichnung angegeben.Advantageous embodiments of the invention are also specified in the dependent claims, the description and the drawings.

Generell ist es erfindungsgemäß möglich, aber nicht zwingend, das Schneidmesser so zu verformen, dass sich die gewünschte Verstellung zu jedem Zeitpunkt über den gesamten Umfang des Schneidmessers einstellt. Es kann erfindungsgemäß nämlich auch eine Verformung dergestalt erfolgen, dass sich die gewünschte Verstellung lediglich über einen Teilumfangsbereich des Schneidmessers einstellt, z.B. nur ein Teilbereich der Schneide vom Produkt wegbewegt wird. Bei diesem Konzept kann z.B. zwecks sicherer Vermeidung einer Schnitzelbildung die teilweise Verformung des Schneidmessers auf dessen Rotations- und/oder Umlaufgeschwindigkeit abgestimmt werden, d.h. beispielsweise nach Art der zyklischen Blattverstellung beim Rotor eines Hubschraubers wird das Schneidmesser während des Verstellbetriebs, also außerhalb des normalen Schneidebetriebs, stets nur bereichsweise verformt. Insbesondere wird jeweils gerade der Umfangsbereich des weiterhin rotierenden und/oder umlaufenden Schneidmessers verformt, der ohne Verformung in das Produkt einschneiden würde.In general, it is inventively possible, but not mandatory, to deform the cutting blade so that the desired adjustment is established at all times over the entire circumference of the cutting blade. In fact, according to the invention, deformation can also take place in such a way that the desired adjustment is established only over a partial circumferential area of the cutting blade, e.g. only a portion of the cutting edge is moved away from the product. In this concept, e.g. in order to safely avoid chip formation, the partial deformation of the cutting blade is adjusted to its rotational and / or rotational speed, i. For example, according to the type of cyclical pitch adjustment in the rotor of a helicopter, the cutting blade is always only partially deformed during the adjustment, ie outside the normal cutting operation. In particular, in each case just the peripheral region of the further rotating and / or rotating cutting blade is deformed, which would cut into the product without deformation.

Vorzugsweise ist das Schneidmesser derart verformbar, dass eine Schneide des Schneidmessers und/oder ein wenigstens eine Schneide des Schneidmessers umfassender Abschnitt des Schneidmessers zumindest mit einer Komponente in einer Verstellrichtung relativ zu der Messerhalterung bewegbar ist. Die während des Verstellvorgangs zu bewegende Masse kann dadurch auf ein Minimum beschränkt werden, was hinsichtlich einer schnellen, präzisen und zuverlässigen Verstellung vorteilhaft ist. Sollen beispielsweise Leerschnitte durchgeführt werden, so ist es erfindungsgemäß möglich, lediglich einen sonst mit dem Produkt in Eingriff gelangenden Bereich durch Verformung des Schneidmessers gerade so weit vom Produkt wegzubewegen, dass eine Schnitzelbildung verhindert ist.Preferably, the cutting blade is deformable such that a cutting edge of the cutting blade and / or a section of the cutting blade comprising at least one cutting edge of the cutting blade can be moved at least with one component in an adjustment direction relative to the blade holder. The mass to be moved during the adjustment process can thereby be kept to a minimum, which is advantageous in terms of rapid, precise and reliable adjustment. If, for example, idle cuts are to be carried out, then it is possible according to the invention to move away from the product just by way of deformation of the cutting blade only an area otherwise in contact with the product so that chips are prevented.

Vorzugsweise ist die Messerhalterung in einer Verstellrichtung gesehen ortsfest. Insbesondere kann die Messerhalterung relativ zu einem Grundgestell der Vorrichtung in Verstellrichtung gesehen ortsfest sein, z.B. einem Slicer-Gestell oder einem Slicer-Rahmen. Abgesehen von der Verstellrichtung kann die Messerhalterung natürlich bewegbar sein, beispielsweise entsprechend einem rotierenden und/oder umlaufenden Antrieb des Schneidmessers oder entsprechend anderen Einstell- oder Verstellbewegungen des zugehörigen Messerkopfes oder Schneidkopfes. Für die Messerhalterung muss bei einer derartigen Ausgestaltung keine eigene Verstellvorrichtung bereitgestellt werden.Preferably, the knife holder is stationary in an adjustment seen. In particular, the knife holder can be fixed relative to a base frame of the device in the direction of adjustment, e.g. a slicer rack or a slicer frame. Apart from the adjustment, the knife holder can of course be movable, for example, according to a rotating and / or rotating drive of the cutting blade or other adjustment or adjustment movements of the associated cutter head or cutting head. For the knife holder, no separate adjusting device must be provided in such a configuration.

Die Verstellrichtung verläuft vorzugsweise parallel zur Messerachse und/oder zur Mittelachse, da dies eine besonders einfache Konstruktion ermöglicht.The adjustment direction preferably runs parallel to the blade axis and / or to the center axis, since this allows a particularly simple construction.

Gemäß einer Ausgestaltung der Erfindung ist die Verstelleinrichtung dazu ausgebildet, einen bezüglich der Messerachse radial äußeren Abschnitt des Schneidmessers relativ zu einem an der Messerhalterung befestigten radial inneren Abschnitt zu bewegen. Der üblicherweise zur Befestigung des Schneidmessers an der Messerhalterung vorgesehene achsnahe Bereich kann also ortsfest bleiben, während sich beim Verformen der Schneidenbereich - bei in Verstellrichtung unbeweglicher Messerhalterung und aufrechterhaltener Befestigung des Schneidmessers an der Messerhalterung - z.B. von dem vorderen Produktende wegbewegt.According to one embodiment of the invention, the adjusting device is adapted to move relative to the blade axis radially outer portion of the cutting blade relative to a fixed to the blade holder radially inner portion. The near-axis region usually provided for fastening the cutting blade to the knife holder can thus remain stationary, while moving away during deformation of the cutting area - in the direction of immovable knife holder and maintained attachment of the cutting blade on the knife holder - eg from the front end of the product.

Die Verstelleinrichtung kann insbesondere dazu ausgebildet sein, an dem Schneidmesser anzugreifen. Die Verformung kann also durch Beaufschlagen des Schneidmessers selbst erfolgen. Zu diesem Zweck können beispielsweise angetriebene Druckstößel oder Druckringe vorgesehen sein. Auch berührungslose Beaufschlagungen z.B. mittels elektromagnetischer Wechselwirkung sind erfindungsgemäß möglich.The adjusting device may in particular be designed to engage the cutting blade. The deformation can thus be done by applying the cutting blade itself. For example, driven pressure rams or pressure rings can be provided for this purpose. Non-contact applications, e.g. By means of electromagnetic interaction are possible according to the invention.

Vorzugsweise ist das Schneidmesser in sich verformbar.Preferably, the cutting blade is deformable in itself.

Gemäß einer Ausführungsform der Erfindung weist das Schneidmesser wenigstens einen Biegebereich auf, welcher aufgrund seiner Formgebung und/oder Beschaffenheit zur Verformung durch die Verstelleinrichtung ausgebildet ist. Das Schneidmesser ist also von vorn herein so gestaltet, dass eine leichte und zuverlässige Verformbarkeit gegeben ist. Der Biegebereich kann in einfacher Weise durch eine Verjüngung und/oder eine reduzierte Materialstärke gebildet sein. Insbesondere könnte ein bezüglich der Messerachse radial innerer Bereich des Schneidmessers dünner ausgebildet sein als ein radial äußerer Bereich. Alternativ könnte das Schneidmesser auch aus Abschnitten unterschiedlicher Beschaffenheit zusammengesetzt sein, wobei ein Abschnitt aus relativ weichem Material den Biegebereich bildet. Das Schneidmesser kann auch grundsätzlich biegsam ausgebildet sein, d.h. der Biegebereich kann sich im Wesentlichen über die gesamte Messerfläche oder Ausdehnung des Messers erstrecken.According to one embodiment of the invention, the cutting blade has at least one bending region, which is formed due to its shape and / or condition for deformation by the adjusting device. The cutting blade is so designed from the outset that a slight and reliable deformability is given. The bending region can be formed in a simple manner by a taper and / or a reduced material thickness. In particular, a radially inner region of the cutting blade with respect to the blade axis could be made thinner than a radially outer region. Alternatively, the cutting blade could be composed of sections of different nature, wherein a portion of relatively soft material forms the bending region. The cutting blade may also be basically flexible, i. the bending region may extend substantially over the entire blade surface or extent of the blade.

Bevorzugt ist das Schneidmesser zumindest bereichsweise elastisch verformbar und/oder federnd ausgebildet. Dies ist insofern vorteilhaft, als sich das Schneidmesser dann selbsttätig zurückstellen kann, sobald durch die Verstelleinrichtung keine Verformungskraft mehr ausgeübt wird. Für die Rückstellbewegung muss die Verstelleinrichtung bei dieser Ausgestaltung also keine aktive Kraft aufwenden.Preferably, the cutting blade is at least partially elastically deformable and / or resilient. This is advantageous in that the cutting blade can then automatically reset as soon as no deformation force is exerted by the adjusting device becomes. For the return movement, the adjustment must therefore spend no active force in this embodiment.

Das Schneidmesser kann alternativ oder zusätzlich auch wenigstens ein elastisch verformbares und/oder federndes Element umfassen, um eine automatische Rückstellung zu ermöglichen oder zu unterstützen. Insbesondere kann wenigstens eine Blattfeder oder Tellerfeder an dem Schneidmesser vorgesehen sein, bevorzugt an einem bezüglich der Messerachse radial inneren Abschnitt.The cutting blade may alternatively or additionally also comprise at least one elastically deformable and / or resilient element to enable or assist an automatic reset. In particular, at least one leaf spring or cup spring may be provided on the cutting blade, preferably on a radially inner portion relative to the blade axis.

Gemäß einer weiteren Ausführungsform weist die Verstelleinrichtung wenigstens ein Stellglied auf, welches dazu ausgebildet ist, zum Verformen des Schneidmessers eine Zug- und/oder Druckkraft auf das Schneidmesser auszuüben. Insbesondere kann das Stellglied elektrisch, hydraulisch oder pneumatisch betätigbar sein. Je nach Anwendung kann das Stellglied direkt auf das Schneidmesser einwirken oder es können geeignete Übertragungselemente zur Vermittlung der Stellkraft des Stellglieds an das Schneidmesser vorgesehen sein.According to a further embodiment, the adjusting device has at least one actuator, which is designed to exert a tensile and / or compressive force on the cutting blade for deforming the cutting blade. In particular, the actuator may be electrically, hydraulically or pneumatically actuated. Depending on the application, the actuator may act directly on the cutting blade or it may be provided suitable transmission elements for imparting the actuating force of the actuator to the cutting blade.

Das Stellglied kann ein an der Messerhalterung verschiebbares Element umfassen, das ĂĽber eine Koppeleinrichtung mit dem Schneidmesser in Verbindung steht. Mittels des verschiebbaren Elements und der Koppeleinrichtung kann die zur Verformung vorgesehene Kraft auf einfache Weise von einem Antriebselement des Stellglieds auf das Schneidmesser ĂĽbertragen werden. Beispielsweise kann es sich bei dem verschiebbaren Element um eine SchiebehĂĽlse handeln, die gleitend auf einem Wellenabschnitt der Messerhalterung gelagert ist.The actuator may comprise a displaceable on the knife holder element which is connected via a coupling device with the cutting blade. By means of the displaceable element and the coupling device, the force provided for the deformation can be transmitted in a simple manner from a drive element of the actuator to the cutting blade. For example, the displaceable element may be a sliding sleeve which is slidably mounted on a shaft portion of the knife holder.

Die Koppeleinrichtung kann wenigstens einen Gelenkhebel umfassen, insbesondere mehrere an dem verschiebbaren Element in Umfangsrichtung verteilt angeordnete Gelenkhebel. Die Gelenkhebel können nach Art eines Regenschirms an einem Ende der Schiebehülse angebracht sein und am anderen Ende am Schneidmesser angreifen. Bedarfsweise können die Gelenkhebel jeweils zwei oder mehr gegeneinander verschwenkbare Teile umfassen oder auf andere Weise längenveränderlich ausgebildet sein.The coupling device may comprise at least one articulated lever, in particular a plurality of the displaceable element in the circumferential direction distributed articulated levers. The toggle levers may be attached to one end of the sliding sleeve in the manner of an umbrella and to engage the cutting blade at the other end. If necessary, the articulated levers may each comprise two or more mutually pivotable parts or be formed variable in length in other ways.

Um eine zeitlich exakt koordinierte Messerverformung zu ermöglichen, kann eine Steuereinrichtung vorgesehen sein, welche dazu ausgebildet ist, während eines Schneidebetriebs bei Bedarf zur Durchführung wenigstens einer Zusatzfunktion die Verstelleinrichtung zu betätigen.In order to enable a precisely timed knife deformation, a control device may be provided which is designed to actuate the adjusting device during a cutting operation as needed for carrying out at least one additional function.

Gemäß einer weiteren Ausführungsform der Erfindung ist die Messerhalterung ein Bestandteil eines Messerkopfes, der in Verstellrichtung gesehen ortsfest ist. Dadurch dass der Messerkopf ortsfest ist, kann eine entsprechende Verstelleinrichtung für den Messerkopf eingespart werden.According to a further embodiment of the invention, the knife holder is a component of a cutter head, which is stationary in the adjustment direction. Because the cutter head is stationary, a corresponding adjusting device for the cutter head can be saved.

Der Messerkopf kann als Sichelmesserkopf für ein um die Messerachse rotierendes Sichelmesser ausgebildet sein. Alternativ kann der Messerkopf als Kreismesserkopf für ein um die Messerachse rotierendes und um die Mittelachse planetarisch umlaufendes Kreismesser ausgebildet sein. Dem Messerkopf kann weiterhin wenigstens ein Rotationsantrieb zugeordnet sein, welcher zusammen mit dem Messerkopf an oder in einem gestellfesten Schneidkopfgehäuse angeordnet ist. Auch der Rotationsantrieb muss erfindungsgemäß zum Verstellen des Schneidmessers nicht zwingend bewegt werden, da die Verstellbewegung durch die Verformung des Schneidmessers selbst bewerkstelligt wird. Wenn es sich um einen Kreismesserkopf handelt, dann kann für die Rotation des Schneidmessers einerseits und für den Umlauf des Schneidmessers, d.h. für die Rotation um die Mittelachse, andererseits ein einziger gemeinsamer Antrieb vorgesehen sein. Es ist aber auch möglich, für jede dieser Bewegungen einen eigenen und/oder separaten Antrieb, insbesondere voneinander unabhängige Antriebe, vorzusehen.The cutter head can be designed as a sickle cutter head for a sickle knife rotating about the cutter axis. Alternatively, the cutter head can be designed as a circular blade head for a circular blade rotating around the blade axis and rotating planetary about the central axis. The cutter head may further be associated with at least one rotary drive, which is arranged together with the cutter head on or in a frame-fixed cutting head housing. Also, the rotary drive according to the invention need not necessarily be moved for adjusting the cutting blade, since the adjustment is accomplished by the deformation of the cutting blade itself. If it is a circular knife head, then for the rotation of the cutting blade on the one hand and for the circulation of the cutting blade, ie for rotation about the central axis, on the other hand, a single common drive can be provided. But it is also possible for each of these movements one own and / or separate drive, in particular independent drives to provide.

Gemäß einer weiteren Ausführungsform ist das Schneidmesser derart verformbar, dass sich der Abstand zwischen dem Schneidmesser und einer Bezugsebene, die parallel zu einer durch die Schneide des in einer Schneidstellung befindlichen Schneidmessers definierten Schneidebene verläuft, verändert. Als Bezugsebene ist z.B. diejenige Ebene zu verstehen, in welcher zumindest näherungsweise während des Schneidebetriebs das vordere Ende des aufzuschneidenden Produktes, also die momentane Schnittfläche des Produktes, liegt. Die Verstellbewegung des Schneidmessers schafft einen ausreichend großen Abstand zwischen der stets durch die Schneide des Schneidmessers definierten Schneidebene und dem vorderen Produktende, wodurch eine Schnitzelbildung verhindert wird. Die Bezugsebene kann auch mit derjenigen Ebene zusammenfallen, in der die Schneidebene liegt, wenn sich das Schneidmesser in der Schneidstellung befindet. Auch dann, wenn sich das Schneidmesser nicht in der Schneidstellung befindet, also zwischen Beginn und Abschluss des Verstellvorgangs, kann die Bezugsebene parallel zur Schneidebene verlaufen. Dies hängt von der konkreten Art und Weise der Verstellbewegung des Schneidmessers ab.According to a further embodiment, the cutting blade is deformable in such a way that the distance between the cutting blade and a reference plane which runs parallel to a cutting plane defined by the cutting edge of the cutting blade located in a cutting position changes. As a reference plane, e.g. to understand that plane in which, at least approximately during the cutting operation, the front end of the product to be sliced, ie the current cutting surface of the product, is located. The adjustment movement of the cutting blade creates a sufficiently large distance between the cutting plane always defined by the cutting edge of the cutting blade and the front end of the product, whereby a Schnitzelbildung is prevented. The reference plane may also coincide with the plane in which the cutting plane is located when the cutting blade is in the cutting position. Even if the cutting blade is not in the cutting position, ie between the beginning and the end of the adjustment process, the reference plane can be parallel to the cutting plane. This depends on the specific way of adjusting the cutting blade.

Vorzugsweise ist das Schneidmesser zur DurchfĂĽhrung wenigstens einer Zusatzfunktion verformbar, insbesondere zur DurchfĂĽhrung von Leerschnitten und/oder zur Schneidspalteinstellung.Preferably, the cutting blade for performing at least one additional function is deformable, in particular for performing blank cuts and / or for cutting gap adjustment.

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

Gemäß Fig. 1 umfasst ein Hochleistungs-Slicer eine Produktzuführung 11, ein Schneidmesser 13 sowie eine Messerhalterung 15 für das Schneidmesser 13. Das Schneidmesser 13 ist hier als Sichelmesser ausgebildet, welches um eine Messerachse A rotiert. Die Messerhalterung 15 ist in einem Lager 17 drehgelagert und umfasst einen Basisabschnitt 19 sowie einen Steckabschnitt 21. Das Schneidmesser 13 ist auf den Steckabschnitt 21 der Messerhalterung 15 aufgesteckt und mittels nicht dargestellter Schrauben an einer Stirnseite des Basisabschnitts 19 befestigt. Ein nicht dargestellter Rotationsantrieb dient dazu, die Messerhalterung 15 mittels eines Antriebsriemens in eine Drehbewegung um die Messerachse A zu versetzen. Die Messerhalterung 15 bildet zusammen mit dem Lager 17 einen Messerkopf 23, der gemeinsam mit dem Rotationsantrieb ortsfest in einem nicht dargestellten Schneidkopfgehäuse des Slicers angebracht ist.According to Fig. 1 a high-performance slicer comprises a product feeder 11, a cutting blade 13 and a knife holder 15 for the cutting blade 13. The cutting blade 13 is here designed as a sickle blade, which rotates about a knife axis A. The knife holder 15 is rotatably mounted in a bearing 17 and comprises a base portion 19 and a plug portion 21. The cutting blade 13 is plugged onto the plug portion 21 of the knife holder 15 and secured by means not shown screws on an end face of the base portion 19. An unillustrated rotary drive serves to put the knife holder 15 by means of a drive belt in a rotational movement about the blade axis A. The knife holder 15 forms together with the bearing 17 a cutter head 23 which is fixedly mounted together with the rotary drive in a cutting head housing, not shown, of the slicer.

Eine Schneide 25 des Schneidmessers 13 definiert unabhängig von dem Betriebszustand des Schneidmessers 13 stets eine rechtwinklig zu der Messerachse A verlaufende Schneidebene S. Auf einer Produktauflage 37 der Produktzuführung 11 befindet sich ein Produktriegel 27, an dessen hinterem Ende Haltekrallen 29 angreifen, welche durch einen nicht dargestellten gesteuerten Antrieb in und gegen eine Produktzuführrichtung P bewegbar sind, was in Fig. 1 durch einen Doppelpfeil dargestellt ist. Mittels der angetriebenen Haltekrallen 29 wird der Produktriegel 27 entlang der Produktzuführrichtung P der Schneidebene S zugeführt. Anstatt eines einzelnen Produktriegels 27 können auch mehrere nebeneinander angeordnete Produktriegel gemeinsam der Schneidebene S zugeführt werden.A cutting edge 25 of the cutting blade 13, regardless of the operating state of the cutting blade 13 always defines a perpendicular to the blade axis A extending cutting plane S. On a product support 37 of the product feeder 11 is a product bar 27, engage at the rear end retaining claws 29, which by a non shown controlled drive in and against a Produktzuführrichtung P are movable, which in Fig. 1 represented by a double arrow. By means of the driven retaining claws 29, the product bar 27 is fed along the product feed direction P to the cutting plane S. Instead of one individual product bars 27 can also be several juxtaposed product bars together the cutting plane S are supplied.

Während des Betriebs des Hochleistungs-Slicers schneidet das rotierende Schneidmesser 13 mit seiner Schneide 25 durch den Produktriegel 27 hindurch und trennt von diesem Produktscheiben 30 ab, wobei es mit einer das Ende der Produktauflage 37 bildenden Schneidkante 31 zusammenwirkt. Das Zusammenfallen der Schneidebene S mit einer durch die Schneidkante 31 definierten Ebene ist hier einer vereinfachenden Darstellung geschuldet. In der Praxis ist zwischen dem Schneidmesser 13 und der Schneidkante 31 ein kleiner, meist einstellbarer Schneidspalt vorhanden, worauf hier aber nicht näher eingegangen zu werden braucht. Die Vorschubgeschwindigkeit des Produktriegels 27 und somit die Dicke der Produktscheiben 30 ist dabei durch eine entsprechende Ansteuerung der angetriebenen Haltekrallen 29 einstellbar. Die abgetrennten Produktscheiben 30 fallen auf der der Produktzuführung 11 abgewandten Messerrückseite auf eine Auflage 33 und können entlang einer Förderrichtung F weitergefördert bzw. weiterverarbeitet, insbesondere einer automatischen Verpackungsanlage (nicht dargestellt) zugeführt werden.During operation of the high-performance slicer, the rotating cutting blade 13 cuts with its cutting edge 25 through the product bar 27 and separates from this product slices 30, wherein it cooperates with a cutting edge 31 forming the end of the product support 37. The coincidence of the cutting plane S with a plane defined by the cutting edge 31 is here due to a simplifying representation. In practice, a small, usually adjustable cutting gap is present between the cutting blade 13 and the cutting edge 31, which need not be discussed here in detail. The feed rate of the product bar 27 and thus the thickness of the product slices 30 can be adjusted by a corresponding control of the driven holding claws 29. The separated product slices 30 fall on the rear side facing away from the product feed 11 on a support 33 and can be further conveyed or further processed along a conveying direction F, in particular an automatic packaging system (not shown) are supplied.

Aus Fig. 1 geht hervor, dass das Aufschneiden des Produktriegels 27 portionsweise erfolgt, d.h. die abgetrennten Produktscheiben 30 bilden Portionen 35, die hier als Scheibenstapel dargestellt sind. Sobald eine Portion 35 fertig gestellt ist, wird diese Portion 35 auf der Auflage 33 in Förderrichtung F abtransportiert. Damit für den Abtransport der fertigen Portionen 35 genügend Zeit zur Verfügung steht, werden bis zum Beginn der Bildung der nächsten Portion 35 die vorstehend erwähnten Leerschnitte ausgeführt, wozu einerseits die auch als Produktvorschub bezeichnete Produktzufuhr - hier also die Haltekrallen 29 - gestoppt und gegebenenfalls zurückgezogen und andererseits das Schneidmesser 13 verformt wird, sodass es die in Fig. 1 gestrichelt dargestellte Stellung einnimmt. In dieser Stellung ist die Schneide 25 des Schneidmessers 13 von dem vorderen Ende des Produktriegels 27 beabstandet, sodass eine Schnitzel- oder Schnipselbildung während der Durchführung von Leerschnitten sicher vermieden wird. Um die Verformung des Schneidmessers 13 herbeizuführen, ist eine durch eine nicht dargestellte Steuereinrichtung gesteuerte Verstelleinrichtung 50 vorgesehen, welche in Fig. 1 lediglich schematisch dargestellt ist.Out Fig. 1 shows that the slicing of the product bar 27 is carried out in portions, ie the separated product slices 30 form portions 35, which are shown here as a slice stack. Once a portion 35 is completed, this portion 35 is transported on the support 33 in the conveying direction F. So that sufficient time is available for the removal of the finished portions 35, the above-mentioned idle cuts are carried out until the beginning of the formation of the next portion 35, for which purpose the product feed called product feed - in this case the holding claws 29 - is stopped and, if necessary, withdrawn and on the other hand, the cutting blade 13 is deformed so that it is in Fig. 1 shown in dashed line position. In this position, the cutting edge 25 of the cutting blade 13 is spaced from the front end of the product bar 27, so that a Schnitzel or Schnipselbildung is safely avoided during the execution of blanks. In order to bring about the deformation of the cutting blade 13, an adjusting device 50 controlled by a control device, not shown, is provided, which in FIG Fig. 1 is shown only schematically.

Beim Verformen des Schneidmessers 13 wird, wie aus Fig. 1 ersichtlich ist, ein bezüglich der Messerachse A radial äußerer Abschnitt 61 des Schneidmessers 13 gegenüber einem radial inneren Abschnitt 63 bewegt. Im Bereich des radial inneren Abschnitts 63 ist das Schneidmesser 13 an der Messerhalterung 15 befestigt, weshalb der radial innere Abschnitt 63 während des Verformungsvorgangs zumindest an den Befestigungsstellen festgehalten ist. Das heißt also das Schneidmesser 13 wird bei Aktivierung der Verstelleinrichtung 50 um einen bestimmten Betrag gekrümmt, so dass die Schneide 25 eine Bewegung ausführt, die eine Komponente in der Verstellrichtung V aufweist.When deforming the cutting blade 13, as is Fig. 1 it can be seen, with respect to the blade axis A radially outer portion 61 of the cutting blade 13 relative to a radially inner portion 63 moves. In the region of the radially inner portion 63, the cutting blade 13 is fixed to the blade holder 15, which is why the radially inner portion 63 is held at least at the attachment points during the deformation process. This means that the cutting blade 13 is curved by a certain amount upon activation of the adjusting device 50, so that the cutting edge 25 performs a movement which has a component in the adjustment direction V.

Um eine ausreichende Verformbarkeit des Schneidmessers 13 zu gewährleisten, ist dieses aus einem elastischen Material gefertigt. Weiterhin ist der radial innere Abschnitt 63 gegenüber dem radial äußeren Abschnitt 61 verjüngt, d.h. das Schneidmesser 13 weist im Bereich des radial inneren Abschnitts 63 eine reduzierte Materialstärke auf. Dadurch bildet der radial innere Abschnitt 63 einen Biegebereich, der zur Verformung vorgesehen ist, während der radial äußere Abschnitt 61 relativ steif ist. Zur Unterstützung der Elastizität kann wenigstens ein zusätzliches Federelement vorgesehen sein, was in Fig. 1 jedoch nicht dargestellt ist. Wenn eine durchgeführte Zusatzfunktion zu beenden ist, stellt die Verstelleinrichtung 50 die Kraftausübung auf das Schneidmesser 13 ein und das Schneidmesser 13 nimmt aufgrund seiner elastischen Ausbildung automatisch wieder die in Fig. 1 in durchgezogenen Linien dargestellte Ausgangsstellung (Schneidstellung) ein.In order to ensure sufficient deformability of the cutting blade 13, this is made of an elastic material. Furthermore, the radially inner portion 63 is tapered with respect to the radially outer portion 61, ie the cutting blade 13 has a reduced material thickness in the region of the radially inner portion 63. Thereby, the radially inner portion 63 forms a bending portion provided for deformation while the radially outer portion 61 is relatively rigid. To support the elasticity, at least one additional spring element can be provided, which is in Fig. 1 but not shown. If an additional function has to be completed, the adjusting device stops 50 the exercise of force on the cutting blade 13 and the cutting blade 13 automatically takes back due to its elastic training in Fig. 1 in starting position shown in solid lines (cutting position).

Fig. 2 zeigt eine Ausführungsform der Verstelleinrichtung 50 detaillierter. Zur Vereinfachung sind in der Darstellung des Slicers gemäß Fig. 2 der Produktriegel, die Produktzuführung sowie die Produktauflage weggelassen. Die Verstelleinrichtung 50 umfasst eine auf dem Basisabschnitt 19 der Messerhalterung 15 vorgesehene Schiebehülse 55, welche durch einen nicht dargestellten Stellantrieb entlang der Verstellrichtung V vor und zurückbewegt werden kann. An der Außenfläche der Schiebehülse 55 sind in Umfangsrichtung verteilt angeordnete Gelenkhebel 57 angelenkt, welche an ihrem von der Schiebehülse 55 entfernten Ende an dem Schneidmesser 13 angelenkt sind. Um eine Längenveränderlichkeit der Gelenkhebel 57 bereitzustellen, können diese aus wenigstens zwei gegeneinander verschwenkbaren Teilen zusammengesetzt sein, was in Fig. 2 nicht im Einzelnen dargestellt ist. Bei einer Bewegung der Schiebehülse 55 üben die Gelenkhebel 57 eine Zug- oder Druckkraft in Verstellrichtung V auf den radial äußeren Abschnitt 61 des Schneidmessers 13 aus und biegen das Schneidmesser 13 somit in eine der beiden in Fig. 1 dargestellten Stellungen. Fig. 2 shows an embodiment of the adjustment 50 in more detail. For simplicity, in the presentation of the slicer according to Fig. 2 the product bar, the product feed and the product overlay omitted. The adjusting device 50 comprises a provided on the base portion 19 of the knife holder 15 sliding sleeve 55, which can be moved by an actuator, not shown, along the adjustment direction V back and forth. On the outer surface of the sliding sleeve 55 are distributed in the circumferential direction arranged articulated lever 57 hinged, which are articulated at its end remote from the sliding sleeve 55 on the cutting blade 13. To provide a Längenveränderlichkeit the hinge lever 57, these may be composed of at least two mutually pivotable parts, which in Fig. 2 is not shown in detail. During a movement of the sliding sleeve 55, the articulated levers 57 exert a tensile or compressive force in the adjustment direction V on the radially outer portion 61 of the cutting blade 13 and thus bend the cutting blade 13 in one of the two in Fig. 1 represented positions.

Anstelle der Anordnung aus Schiebehülse 55 und Gelenkhebeln 57 sind verschiedene alternative Übertragungsmechanismen möglich, wie z.B. pneumatisch betätigte Druckstößel oder Druckringe, hydraulische Lösungen oder elektrische bzw. elektromagnetische Anordnungen.Instead of the arrangement of sliding sleeve 55 and articulated levers 57, various alternative transmission mechanisms are possible, such as e.g. pneumatically operated plungers or pressure rings, hydraulic solutions or electrical or electromagnetic arrangements.

Aufgrund des Prinzips der Messerverformung muss zum Durchführen von Zusatzfunktionen bei dem Slicer praktisch nur der radial äußere Abschnitt 61 des Schneidmessers 13 in Bewegung versetzt werden, während alle übrigen Komponenten des Slicers hinsichtlich der Verstellbewegung ortsfest bleiben. Die für ein erwünschtes Verstellen des Schneidmessers 13 zu bewegende Masse ist somit auf einen besonders niedrigen Wert reduziert.Due to the principle of knife deformation practically only the radially outer portion needs to perform additional functions in the slicer 61 of the cutting blade 13 are set in motion, while all other components of the slicer remain stationary with respect to the adjusting movement. The mass to be moved for a desired adjustment of the cutting blade 13 is thus reduced to a particularly low value.
