Description

Schneidvorrichtung cutter

Die vorliegende Erfindung betrifft eine Schneidvorrichtung zum Auf- schneiden von Lebensmittelprodukten, insbesondere einen Hochleistungs- Slicer, mit einem antreibbaren Kreismesser, das um eine Messerachse rotiert, die auf einer Bahn um eine Mittelachse umläuft, und einem an der von einem aufzuschneidenden Produkt abgewandten Seite des Kreismessers vorgesehenen, relativ zu dem Kreismesser drehbaren Abdeckelement.The present invention relates to a cutting device for cutting food products, in particular a high-performance slicer, comprising a drivable circular blade which rotates about a knife axis which rotates on a path about a central axis and a side of the side facing away from a product to be sliced Circular knife provided, rotatable relative to the circular blade cover.

Das Abdeckelement dient bei derartigen Schneidvorrichtungen dazu, ein störendes Anhaften von abgetrennten Produktscheiben am Kreismesser zu verhindern. Die Produktscheiben treten in Kontakt mit dem Abdeckelement und werden daran abgestreift. Auf diese Weise können auch relativ weiche Lebensmittelprodukte mit hoher Schnittfolge aufgeschnitten werden. Eine Schneidvorrichtung mit einem Abdeckelement ist beispielsweise in der EP 0 169 399 Bl beschrieben.The cover member is used in such cutting devices to prevent interference of separated product slices on the circular blade. The product slices come into contact with the cover and are stripped off. In this way, even relatively soft food products can be cut with high cutting rate. A cutting device with a cover element is described, for example, in EP 0 169 399 B1.

Das Abdeckelement, das beispielsweise als flache, zu dem Kreismesser koaxiale Scheibe vorgesehen sein kann, neigt während des Betriebs der Schneidvorrichtung zu einer Eigenrotation um die Messerachse. Eine Eigenrotation des Abdeckelements kann ungünstige Auswirkungen haben, da die Gefahr besteht, dass abgetrennte Produktscheiben durch die rotierende Abdeckscheibe mitgenommen und unkontrolliert weggeschleudert werden.The cover, which may be provided, for example, as a flat, coaxial to the circular blade disc tends during operation of the cutting device to a self-rotation about the blade axis. A self-rotation of the cover can have unfavorable effects, since there is a risk that separated product slices are taken by the rotating cover and ejected uncontrollably.

Es ist daher eine Aufgabe der Erfindung, Schneidvorrichtungen der genannten Art hinsichtlich der Produktscheibenablage zu verbessern. Die Aufgabe wird durch eine Schneidvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Erfindungsgemäß ist eine Haltevorrichtung vorgesehen, die dazu ausgebildet ist, einer Eigenrotation des Abdeckelements um die Messerachse entgegenzuwirken, insbesondere eine Eigenrotation des Abdeckelements um die Messerachse zu verhindern. Durch die Haltevorrichtung kann erreicht werden, dass das Abdeckelement nicht von der Rotationsbewegung des Kreismessers mitgenommen wird, sondern stillsteht oder nur relativ geringfügige Eigenrotationsbewegungen ausführt. Dadurch wird erreicht, dass die durch das rotierende Kreismesser abge- schnittenen Produktscheiben zuverlässig an der Abdeckscheibe abgestreift werden. Durch dieses geordnete Abstreifen kann eine exakte und reproduzierbare Ablageposition der Produktscheiben erzielt werden. Insbesondere können auch weiche und schwer aufzuschneidende Lebensmittelprodukte zuverlässig verarbeitet werden.It is therefore an object of the invention to improve cutting devices of the type mentioned in terms of product disc tray. The object is achieved by a cutting device with the features of claim 1. According to the invention, a holding device is provided, which is designed to counteract self-rotation of the cover element about the blade axis, in particular to prevent self-rotation of the cover element about the blade axis. By the holding device can be achieved that the cover is not taken away by the rotational movement of the circular blade, but stands still or performs only relatively minor self-rotation movements. This ensures that the product slices cut off by the rotating circular blade are reliably scraped off the cover disc. By this orderly stripping an exact and reproducible storage position of the product slices can be achieved. In particular, soft and hard-to-cut food products can be reliably processed.

Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen, der Beschreibung sowie der Zeichnung angegeben.Further developments of the invention are specified in the dependent claims, the description and the drawings.

Die Haltevorrichtung kann insbesondere dazu ausgebildet sein, das Ab- deckelement festzuhalten. Es ist also kein eigener Antrieb für das Abdeckelement notwendig, sondern es genügt, dieses durch einfache Maßnahmen gegenüber der Umgebung zu fixieren.The holding device can in particular be designed to hold the cover element. So it is not a separate drive for the cover necessary, but it is sufficient to fix this by simple measures relative to the environment.

Vorzugsweise wirkt die Haltevorrichtung mit der von dem Kreismesser abgewandten Seite des Abdeckelements zusammen. Von dieser Seite aus ist das Abdeckelement leicht zugänglich und kann an einem geeigneten Angriffspunkt gehalten werden.Preferably, the holding device cooperates with the side facing away from the circular blade side of the cover. From this side, the cover is easily accessible and can be kept at a suitable point.

Die Haltevorrichtung kann das Abdeckelement mit einem feststehenden Element, insbesondere einem Rahmen oder einem Gehäuse der Schneid- Vorrichtung, koppeln. Das Abdeckelement wird also an einem gestellfesten Bauteil festgelegt, sodass ein sicherer Stillstand gewährleistet ist.The holding device may comprise the cover element with a stationary element, in particular a frame or a housing of the cutting element. Device, couple. The cover is thus fixed to a frame-fixed component, so that a safe standstill is ensured.

Gemäß einer Ausführungsform umfasst die Haltevorrichtung eine Gelenk- armanordnung. Da das Abdeckelement stets mit dem Kreismesser in Verbindung steht, läuft es während des Betriebs der Schneidvorrichtung um die Mittelachse um. Eine Gelenkarmanordnung ermöglicht es, das Abdeckelement trotz dieser Umlaufbewegung an einem gestellfesten Bauteil zu fixieren.According to one embodiment, the holding device comprises an articulated arm arrangement. Since the cover member is always in communication with the circular blade, it circulates around the central axis during operation of the cutting device. An articulated arm arrangement makes it possible to fix the cover element in spite of this circulating movement on a frame-fixed component.

Gemäß einer bevorzugten Ausführungsform umfasst die Gelenkarmanordnung einen ersten Gelenkarm und einen zweiten Gelenkarm, die relativ zueinander bewegbar, insbesondere um eine parallel zur Messerachse verlaufende Schwenkachse relativ zueinander verschwenkbar, sind. Der zweite Gelenkarm kann dabei an dem feststehenden Element angelenkt sein und der erste Gelenkarm kann drehfest mit dem Abdeckelement verbunden sein. Der erste Gelenkarm hält somit das Abdeckelement gegenüber der Umgebung fest, während der zweite Gelenkarm der Anbindung des ersten Gelenkarms an das feststehende Element dient. Durch die Verschwenkbarkeit der Gelenkarme kann der variable Abstand des umlaufenden Abdeckelements zu dem feststehenden Element ausgeglichen werden.According to a preferred embodiment, the articulated arm arrangement comprises a first articulated arm and a second articulated arm which are movable relative to one another, in particular pivotable relative to one another about a pivot axis extending parallel to the knife axis. The second articulated arm can be articulated to the fixed element and the first articulated arm can be connected in a rotationally fixed manner to the covering element. The first articulated arm thus holds the cover element against the environment, while the second articulated arm serves to connect the first articulated arm to the stationary element. Due to the pivotability of the articulated arms, the variable distance of the encircling cover member can be compensated for the fixed element.

Vorzugsweise ist der erste Gelenkarm an zwei voneinander beabstandeten Stellen mit dem Abdeckelement verbunden. Auf diese Weise ist gewährleistet, dass das Abdeckelement durch den Gelenkarm sicher festgehalten wird und auch unter größerer Belastung keine Verdrehung des Gelenkarms relativ zu dem Abdeckelement um die Messerachse möglich ist. Der erste Gelenkarm kann zwei ausgehend von dem zweiten Gelenkarm auseinanderlaufende, insbesondere in einem spitzen Winkel zueinander stehende, Schenkel aufweisen, deren eines Ende jeweils mit dem Abdeckelement verbunden ist. Beispielsweise kann es sich bei dem ersten Ge- lenkarm um ein V-förmiges Bauteil mit einem Scheitelabschnitt und zwei freistehenden Enden handeln. Der Scheitelabschnitt kann an dem zweiten Gelenkarm angelenkt sein, während die freistehenden Enden mit dem Abdeckelement verbunden sein können. Ein derartiges Bauteil kann leicht und dennoch stabil ausgeführt werden.Preferably, the first articulated arm is connected at two spaced locations with the cover. In this way, it is ensured that the cover is securely held by the articulated arm and no rotation of the articulated arm relative to the cover member about the knife axis is possible even under greater load. The first articulated arm can have two legs extending apart from the second articulated arm, in particular at an acute angle to one another, one end of which is in each case connected to the cover element. For example, the first articulated arm can be a V-shaped component with a vertex section and two freestanding ends. The apex portion may be hinged to the second articulating arm while the freestanding ends may be connected to the covering member. Such a component can be easily and yet stably executed.

Bevorzugt definiert die Gelenkarmanordnung Anlenkpunkte, die im Wesentlichen in einer parallel zu einer Schneidebene des Kreismessers verlaufenden Ebene liegen. Während der Schneidbewegung bewegen sich die Gelenkarme somit in einer gemeinsamen Ebene und benötigen keinen zusätzlichen Bauraum entlang der Messerachse. Aufgrund der Umlaufbewegung des Kreismessers und des mit ihm in Verbindung stehenden Abdeckelements kann es bei einer derartigen Konfiguration zu geringfügigen Oszillationsbewegungen des Abdeckelements gegenüber der Umgebung kommen, welche jedoch im Hinblick auf die Ablage der Produktscheiben unkritisch sind.Preferably, the articulated arm assembly defines articulation points that lie substantially in a plane parallel to a cutting plane of the circular blade. During the cutting movement, the articulated arms thus move in a common plane and require no additional space along the knife axis. Due to the orbiting motion of the circular blade and the cover member associated with it, in such a configuration, slight oscillatory movements of the cover member with respect to the environment may occur, which, however, are not critical with respect to the storage of product slices.

Gemäß einer alternativen oder zusätzlichen Ausführungsform umfasst die H alte Vorrichtung einen torsionssteifen Koppelstab. Ein derartiger Koppelstab kann insbesondere von der Seite aus direkt an das Abdeckelement herangeführt und an diesem befestigt sein. Diese Variante zeichnet sich durch eine große Einfachheit aus.According to an alternative or additional embodiment, the old device comprises a torsionally stiff coupling rod. Such a coupling rod can be brought in particular from the side directly to the cover and attached to this. This variant is characterized by a great simplicity.

Der Koppelstab ist vorzugsweise längenveränderlich, um auch dann eine dauerhafte Kopplung von Abdeckelement und einem feststehenden EIe- ment zu gewährleisten, wenn der Koppelstab abseits der Mittelachse an dem feststehenden Element befestigt ist und somit der Abstand zwischen den beiden Befestigungspunkten des Koppelstabs während der Umlaufbewegung des Abdeckelements variiert. Durch die Längenveränderlichkeit des Koppelstabs wird die Abstandsvariation kompensiert.The coupling rod is preferably variable in length in order to ensure permanent coupling of the cover element and a fixed element even when the coupling rod is away from the central axis the fixed element is fixed and thus varies the distance between the two attachment points of the coupling rod during the orbital movement of the cover. Due to the Längenveränderlichkeit the coupling rod, the distance variation is compensated.

Der Koppelstab kann mittels zweier Anbindungsgelenke drehfest mit dem Abdeckelement und mit dem feststehenden Element in Eingriff stehen. Jegliche Eigenrotation des Abdeckelements um die Messerachse kann bei dieser Variante verhindert werden, also insbesondere auch die vorstehend erwähnten geringfügigen Oszillationsbewegungen.The coupling rod can be non-rotatably by means of two connecting joints with the cover and with the stationary element in engagement. Any self-rotation of the cover element about the blade axis can be prevented in this variant, so in particular also the above-mentioned slight oscillatory movements.

Gemäß einer Weiterbildung kann der Koppelstab um seine Längsachse rotierend antreibbar sein, um eine Rotation des Abdeckelements mit beliebiger Drehzahl herbeizuführen. Eine einstellbare Rotation des Abdeck- elements relativ zu dem Kreismesser um die Messerachse kann je nach Anwendung sinnvoll sein, um beispielsweise die Schnittgutpositionierung gezielt zu beeinflussen.According to a development, the coupling rod can be driven to rotate about its longitudinal axis, in order to bring about a rotation of the cover element at any desired speed. Depending on the application, an adjustable rotation of the cover element relative to the circular blade about the blade axis may be expedient in order, for example, to influence the clippings positioning in a targeted manner.

Vorzugsweise umfasst das Abdeckelement eine zu dem Kreismesser koaxi- ale Scheibe, die sich radial bis zum Bereich der Schneide des Kreismessers erstreckt. Somit treten die abgetrennten Produktscheiben weitgehend vollflächig mit dem Abdeckelement in Kontakt, wodurch ein sicheres Abstreifen ohne Anhaftungsprobleme am Kreismesser ermöglicht wird.The cover element preferably comprises a disk which is coaxial with the circular blade and which extends radially as far as the region of the cutting edge of the circular blade. Thus, the separated product slices contact substantially the entire surface with the cover in contact, whereby a secure stripping without adhesion problems on the circular blade is made possible.

Das Abdeckelement ist vorzugsweise auf dem Kreismesser gelagert. Es ist somit kein eigener Antrieb für die dem Kreismesser folgende Umlaufbewegung des Abdeckelements erforderlich.The cover is preferably mounted on the circular blade. It is thus not a separate drive for the circular blade the following rotational movement of the cover required.

Das Abdeckelement ist bevorzugt an der von dem Kreismesser abgewand- ten Seite mit Erhebungen versehen. Derartige Erhebungen können die Ablage von Produktscheiben weiter verbessern, da ein unerwünschtes Anhaften an dem stillstehenden Abdeckelement verhindert wird.The cover element is preferably provided on the side facing away from the circular blade side with elevations. Such surveys may be the Further improve storage of product slices, since unwanted adhesion to the stationary cover is prevented.

Die Erfindung wird im Folgenden unter Bezugnahme auf die Zeichnungen beispielhaft beschrieben.The invention will now be described by way of example with reference to the drawings.

Fig. 3, bei welcher sich das Kreismesser in einer zweiten Position befindet. Gemäß Fig. 1 ist ein scheibenförmiges Kreismesser 10 drehbar gelagert und mit einem nicht dargestellten Antrieb verbunden, der in der Lage ist, das Kreismesser 10 um eine Messerachse M rotierend anzutreiben. Eine Exzenterschwinge 14 bewirkt ferner, dass das Kreismesser 10 auf einer Kreisbahn um eine Mittelachse Z planetarisch umläuft. Es ist möglich, einen gemeinsamen Antriebsmotor für die Rotationsbewegung um die Messerachse M sowie für die Umlaufbewegung um die Mittelachse Z vorzusehen. Alternativ ist es auch möglich, für jede Achse M, Z einen eigenen Antriebsmotor vorzusehen.Fig. 3, wherein the circular blade is in a second position. 1, a disc-shaped circular blade 10 is rotatably mounted and connected to a drive, not shown, which is able to drive the circular blade 10 about a knife axis M rotating. An eccentric rocker 14 also causes the circular blade 10 to orbit around a central axis Z in a circular path. It is possible to provide a common drive motor for the rotational movement about the knife axis M and for the circulating movement about the central axis Z. Alternatively, it is also possible to provide a separate drive motor for each axis M, Z.

Koaxial zu dem Kreismesser 10 ist ein Abdeckelement 24 gelagert, das hier als hauben- oder tellerartig gewölbte Abdeckscheibe ausgebildet ist. Die Abdeckscheibe 24 ist relativ zu dem Kreismesser 10 um die Messerachse M drehbar und erstreckt sich radial bis in den Bereich der Schneide 26 des Kreismessers 10. Somit ist eine Seite des Kreismessers 10 beinahe vollflächig durch das Abdeckelement 24 abgedeckt.Coaxially to the circular blade 10, a cover 24 is mounted, which is designed here as a hood or plate-like curved cover. The cover plate 24 is rotatable relative to the circular blade 10 about the knife axis M and extends radially into the region of the cutting edge 26 of the circular blade 10. Thus, one side of the circular blade 10 is almost completely covered by the cover 24.

Um eine Eigenrotation der Abdeckscheibe 24 um die Messerachse M zu verhindern, ist eine Haltevorrichtung vorgesehen, die bei der Ausfüh- rungsform gemäß Fig. 1 als Gelenkarmanordnung 30 ausgebildet ist. Die Gelenkarmanordnung 30 umfasst einen ersten Gelenkarm 32 und einen zweiten Gelenkarm 34, welche um eine parallel zur Messerachse M verlaufende Schwenkachse relativ zueinander verschwenkbar sind. Ein erstes Ende 36 des zweiten Gelenkarms 34 ist an einem lediglich schematisch dargestellten Rahmen 38 der Schneidvorrichtung angelenkt und ein zweites Ende 40 des zweiten Gelenkarms 34 ist an dem ersten Gelenkarm 32 angelenkt. Der erste Gelenkarm 32 weist zwei Schenkel 42 und 43 auf, die an einem Scheitelabschnitt 44 miteinander verbunden sind und davon ausgehend in einem spitzen Winkel W auseinander laufen. An dem Schei- telabschnitt 44 ist das zweite Ende 40 des zweiten Gelenkarms 34 ange- lenkt. Beide Schenkel 42, 43 sind an einem dem Scheitelabschnitt 44 entgegengesetzten Endabschnitt 45 des ersten Gelenkarms 32 fest mit der Abdeckscheibe 24 verbunden, zum Beispiel verschraubt oder vernietet. Die entsprechenden Befestigungsstellen 46, 47 befinden sich abseits der Messerachse M. Zur Stabilisierung des ersten Gelenkarms 32 ist ferner ein halbkreisförmig gekrümmter Verbindungsholm 48 vorgesehen, welcher um die Messerachse M herum verläuft und die beiden Schenkel 42, 43 an dem Endabschnitt 45 miteinander verbindet. Die durch die Gelenkarmanordnung 30 definierten Anlenkpunkte 49, 50 sowie die Befestigungsstellen 46, 47 an der Abdeckscheibe 24 liegen in einer gemeinsamen Ebene, welche parallel zu der Schneidebene des Kreismessers 10 und nur geringfügig versetzt zu dieser verläuft. Während der Umlaufbewegung des Kreismessers 10 bleiben die Anlenkpunkte 49, 50 sowie die Befestigungsstellen 46, 47 stets in der gemeinsamen Ebene.In order to prevent a self-rotation of the cover disk 24 about the knife axis M, a holding device is provided, which in the embodiment according to FIG. 1 is designed as an articulated arm arrangement 30. The articulated arm arrangement 30 comprises a first articulated arm 32 and a second articulated arm 34, which are pivotable relative to one another about a pivot axis extending parallel to the knife axis M. A first end 36 of the second articulated arm 34 is articulated to a frame 38 of the cutting device, shown only schematically, and a second end 40 of the second articulated arm 34 is articulated to the first articulated arm 32. The first articulated arm 32 has two legs 42 and 43, which are connected to one another at a vertex portion 44 and run away therefrom at an acute angle W. The second end 40 of the second articulated arm 34 is attached to the slotted portion 44. directs. Both legs 42, 43 are fixedly connected to the crown portion 44 opposite end portion 45 of the first link arm 32 with the cover plate 24, for example screwed or riveted. The corresponding attachment points 46, 47 are located away from the blade axis M. To stabilize the first link arm 32, a semicircular curved connecting bar 48 is further provided, which extends around the blade axis M around and connects the two legs 42, 43 to each other at the end portion 45. The pivot points defined by the Gelenkarmanordnung 30 49, 50 and the attachment points 46, 47 on the cover 24 are in a common plane, which is parallel to the cutting plane of the circular blade 10 and only slightly offset from this. During the orbital movement of the circular blade 10, the articulation points 49, 50 and the attachment points 46, 47 always remain in the common plane.

Während des Betriebs der Schneidvorrichtung nähert sich, wie in Fig. 2A dargestellt ist, das Kreismesser 10 auf seiner Umlaufbahn einem aufzuschneidenden Produktriegel 55, der sich auf einer Produktzuführung 57 befindet und mittels eines nicht dargestellten gesteuerten Antriebs auto- matisch vorgeschoben wird. Im weiteren Verlauf der planetarischen Umlaufbewegung trennt die Schneide 26 des Kreismessers 10 gemäß Fig. 2B eine Produktscheibe 58 von dem Produktriegel 55 ab. Die Abdeckscheibe 24 sorgt dafür, dass die abgetrennte Produktscheibe 58 nicht an dem Kreismesser 10 haften bleibt, sondern an der Oberfläche der Abdeck- scheibe 24 abgestreift wird. Die konvexe Wölbung der Abdeckscheibe 24 unterstützt das kontrollierte Abstreifen der Produktscheibe 58. Zur weiteren Verbesserung des Abstreifvorgangs sind an der Oberfläche der Abdeckscheibe 24 umlaufende Erhebungen 59 vorgesehen. Durch die Gelenkarmanordnung 30 wird die Abdeckscheibe 24 an dem Rahmen 38 festgelegt. Der variierende Abstand zwischen der mit dem Kreismesser 10 umlaufenden Abdeckscheibe 24 und dem Rahmen 38 wird dabei durch die Schwenkbewegung der beiden Gelenkarme 32, 34 kom- pensiert, wie auch in Fig. 2A und 2B zu erkennen ist. Es ergibt sich während der Umlaufbewegung aufgrund der veränderlichen Winkelstellung der beiden Gelenkarme 32, 34 eine geringfügige, oszillierende Drehung der Abdeckscheibe 24 um die Messerachse M. Diese Oszillationsbewegung weist jedoch nur einen äußerst geringen Hub auf und ist daher einer ex- akten Produktscheibenablage nicht abträglich. Die abgetrennte Produktscheibe 58 fällt positionsgenau von der Abdeckscheibe 24 ab und kann in gewünschter Weise weiterverarbeitet, insbesondere einer automatischen Ablage-, Transport- und/ oder Verpackungslinie zugeführt, werden.During operation of the cutting device, as shown in FIG. 2A, the circular blade 10 in its orbit approaches a product bar 55 to be sliced, which is located on a product feed 57 and automatically advanced by means of a controlled drive, not shown. In the further course of the planetary orbital motion, the cutting edge 26 of the circular blade 10 according to FIG. 2B separates a product wafer 58 from the product crucible 55. The cover plate 24 ensures that the separated product wafer 58 does not adhere to the circular blade 10, but is stripped on the surface of the cover plate 24. The convex curvature of the cover 24 supports the controlled stripping of the product wafer 58. To further improve the stripping process 24 circumferential projections 59 are provided on the surface of the cover. By the Gelenkarmanordnung 30, the cover 24 is fixed to the frame 38. The varying distance between the cover disk 24 rotating with the circular blade 10 and the frame 38 is compensated by the pivotal movement of the two articulated arms 32, 34, as can also be seen in FIGS. 2A and 2B. As a result of the variable angular position of the two articulated arms 32, 34, there is a slight, oscillating rotation of the cover disk 24 about the knife axis M during the circulating movement. However, this oscillation movement has only a very small stroke and is therefore not detrimental to an exact product disk placement. The separated product slice 58 falls exactly in position from the cover plate 24 and can be further processed in the desired manner, in particular an automatic filing, transport and / or packaging line supplied, are.

In Fig. 3 ist eine Schneidvorrichtung gemäß einer zweiten Ausführungsform der Erfindung dargestellt, wobei äquivalente Komponenten mit den gleichen Bezugszeichen wie bei der ersten Ausführungsform bezeichnet sind. Die Haltevorrichtung zum Festhalten der Abdeckscheibe 24 ist hier als torsionssteifer und längenveränderlicher Koppelstab 60 ausgebildet. Der Koppelstab 60 steht mittels zweier Anbindungsgelenke 62, 64 drehfest mit der Abdeckscheibe 24 und mit dem Rahmen 38 der Schneidvorrichtung in Eingriff. Da die Anbindungsgelenke 62, 64 drehsteif ausgeführt sind, kann sich die Abdeckscheibe 24 nicht mit dem Kreismesser 10 mitdrehen, sondern bleibt während der Umlaufbewegung im Stillstand. Der Koppelstab 60 greift im Bereich der Messerachse M an dem Abdeckelement 24 an und beschreibt während der Umlaufbewegung des Abdeckelements 24 eine Kegelfläche, wie auch aus den Fig. 4A und 4B hervorgeht. Ein Vorteil der Schneidvorrichtung gemäß der zweiten Ausführungsform besteht darin, dass auf Wunsch ein Antrieb für den Koppelstab 60 vorgesehen sein kann, um eine gezielte Rotation der Abdeckscheibe 24 in einer vorgegebenen Richtung und mit einer definierten Drehzahl zu ermögli- chen. Mit einem derartigen Antrieb kann eine definierte Relativdrehung zwischen dem Kreismesser 10 und der Abdeckscheibe 24 herbeigeführt werden. Eine derartige Relativdrehung kann zur gezielten Beeinflussung des Ablageverhaltens der Schneidvorrichtung herangezogen werden. Durch die Wahl der Geschwindigkeit der Relativdrehung kann der bei jedem Schnitt von der Abdeckscheibe 24 auf die abgetrennte Produktscheibe 58 ausgeübte Bremseffekt gezielt vorgegeben werden, sodass eine besonders exakte Ablage der jeweiligen Produktscheibe 58 möglich ist.In Fig. 3, a cutting device according to a second embodiment of the invention is shown, wherein equivalent components are denoted by the same reference numerals as in the first embodiment. The holding device for holding the cover 24 is formed here as a torsionally stiff and variable-length coupling rod 60. The coupling rod 60 is non-rotatably by means of two connecting joints 62, 64 with the cover plate 24 and with the frame 38 of the cutting device in engagement. Since the connecting joints 62, 64 are designed torsionally rigid, the cover plate 24 can not rotate with the circular blade 10, but remains during the orbital motion at a standstill. The coupling rod 60 engages in the region of the knife axis M on the cover 24 and describes during the orbital movement of the cover 24 has a conical surface, as is apparent from Figs. 4A and 4B. An advantage of the cutting device according to the second embodiment is that, if desired, a drive for the coupling rod 60 can be provided in order to allow a targeted rotation of the cover 24 in a predetermined direction and at a defined speed. With such a drive, a defined relative rotation between the circular blade 10 and the cover 24 can be brought about. Such a relative rotation can be used to selectively influence the storage behavior of the cutting device. By selecting the speed of the relative rotation, the braking effect exerted on the separated product wafer 58 at each cut by the cover disk 24 can be specified in a targeted manner, so that a particularly exact depositing of the respective product wafer 58 is possible.

Insgesamt ist durch das Prinzip des Festhaltens der Abdeckscheibe 24 eine wesentliche Verbesserung des Ablageverhaltens der zugehörigenOverall, by the principle of holding the cover 24 a significant improvement of the storage behavior of the associated

Schneidvorrichtung zu erzielen. Somit können insbesondere auch weiche, ansonsten schwer zu schneidende Lebensmittelprodukte problemlos aufgeschnitten werden. To achieve cutting device. Thus, especially soft, otherwise difficult to cut food products can be cut easily.
