Der Erfindung liegt die Aufgabe zu Grunde, eine Lebensmittel-Schneidemaschine der eingangs genannten Art bereitzustellen, mittels welchem sich auf einfache Weise ein gutes Schneidergebnis erhalten lässt.The invention is based on the object to provide a food cutting machine of the type mentioned, by means of which can be obtained in a simple manner, a good cutting result.

Diese Aufgabe wird bei der eingangs genannten Lebensmittel-Schneidemaschine erfindungsgemäß dadurch gelöst, dass eine Schneidgutabstützungseinrichtung mit mindestens einem Stützelement vorgesehen ist, durch welche Schneidgut beim Schneiden auf einer Stützfläche abstützbar ist, und dass die Schneidgutabstützungseinrichtung mit der Höhenverstellungseinrichtung gekoppelt ist, wobei die Position der wirksamen Stützfläche durch die Höhenposition der Aufnahmeeinrichtung vorgegeben ist.This object is achieved according to the invention in the food cutting machine mentioned above, that a Schneidgutabstützungseinrichtung is provided with at least one support element through which cutting material can be supported during cutting on a support surface, and that the Schneidgutabstützungseinrichtung is coupled to the height adjustment device, wherein the position of the effective support surface is determined by the height position of the receiving device.

Durch die Höhenverstellungseinrichtung lässt sich in Abhängigkeit von dem Durchmesser von Schneidgut ein optimiertes Schneidergebnis erzielen. Damit Querkräfte und damit Zerrkräfte minimiert sind, sollte beim Eindringen des Schneidmessers in Schneidgut ein Geschwindigkeitsvektor möglichst senkrecht zu einer Bewegungsrichtung des Schlittens liegen. Der Eindringpunkt ist von dem Durchmesser des Schneidguts abhängig. Durch die Höhenverstellungseinrichtung lässt sich eine Anpassung erreichen, um so Zerrkräfte zu minimieren.The height adjustment device can be used to achieve an optimized cutting result depending on the diameter of material to be cut. So that lateral forces and therefore tearing forces are minimized, a velocity vector should be as perpendicular as possible to a direction of movement of the carriage when the cutting blade penetrates into the material to be cut. The penetration point depends on the diameter of the material to be cut. By the height adjustment device can be an adjustment to achieve so as to minimize distortion.

Bei der erfindungsgemäßen Lösung ist zusätzlich eine Schneidgutabstützungseinrichtung vorgesehen, durch welche sich Schneidgut beim Schneiden abstützen lässt. Die Schneidgutabstützungseinrichtung bildet ein Gegenelement (Ambosselement) beim Schneiden, um ein optimiertes Schneidergebnis zu erhalten.In the solution according to the invention a Schneidgutabstützungseinrichtung is additionally provided, through which cutting material can be supported during cutting. The Schneidgutabstützungseinrichtung forms a counter element (anvil element) during cutting to obtain an optimized cutting result.

Erfindungsgemäß ist die Schneidgutabstützungseinrichtung mit der Höhenverstellungseinrichtung gekoppelt. Dadurch lässt sich an die jeweilige Höhenposition der Aufnahmeeinrichtung angepasst und insbesondere automatisch die entsprechende Höhe der wirksamen Stützfläche einstellen. Es lässt sich dadurch auf einfache Weise (und auf automatisierte Weise) erreichen, dass eine Auflagefläche der Aufnahmeeinrichtung und die Stützfläche auf der gleichen Höhe liegen und dadurch ein "stetiger" Übergang des Schneidguts und damit wiederum ein optimiertes Schneidergebnis erreicht ist.According to the Schneidgutabstützungseinrichtung is coupled to the height adjustment device. As a result, it is possible to adapt to the respective height position of the receiving device and, in particular, to automatically set the corresponding height of the effective supporting surface. It can thereby be achieved in a simple manner (and in an automated manner) that a bearing surface of the receiving device and the support surface are at the same height and thus a "steady" transition of the material to be cut and thus an optimized cutting result is achieved.

Insbesondere ist eine Steuerungseinrichtung zur Einrichtung der Höhenposition der Aufnahmeeinrichtung vorgegeben. Dadurch lässt sich auf einfache Weise eine automatische Einstellung erreichen; eine manuelle Einstellung der entsprechenden Höhenposition der Aufnahmeeinrichtung ist dadurch nicht notwendig. Die Steuerungseinrichtung gibt entsprechende Signale an die Höhenverstellungseinrichtung ab und die Aufnahmeeinrichtung wird über einen entsprechenden Antrieb in die geeignete Höhenposition verschoben.In particular, a control device for setting the height position of the receiving device is predetermined. This makes it easy to achieve an automatic setting; a manual adjustment of the corresponding height position of the receiving device is not necessary. The control device outputs corresponding signals to the height adjustment device and the receiving device is displaced via a corresponding drive in the appropriate height position.

Bei einer Ausführungsform ist eine Sensoreinrichtung zur Ermittlung eines Schneidgutdurchmessers vorgesehen, wobei die Sensoreinrichtung der Steuerungseinrichtung Signale bereitstellt und die Steuerungseinrichtung die Höhenverstellungseinrichtung zur Einstellung der an den Schneidgutdurchmesser angepassten Höhenposition ansteuert. Dadurch lässt sich automatisch die für das jeweilige Schneidgut richtige Höhenposition einstellen. Die Sensoreinrichtung ist beispielsweise eine optische Sensoreinrichtung, welche den Schneidgutdurchmesser optisch detektiert. Auch andere Sensoreinrichtungen wie beispielsweise mechanische Sensoreinrichtungen oder dergleichen sind möglich.In one embodiment, a sensor device for determining a Schneidgutdurchmessers is provided, wherein the sensor device of the control device provides signals and the control device controls the height adjustment device for adjusting the adjusted to the Schneidgutdurchmesser height position. As a result, it is possible to automatically set the correct height position for the respective item to be cut. The sensor device is, for example, an optical sensor device which optically detects the material to be cut. Other sensor devices such as mechanical sensor devices or the like are possible.

Bei einer alternativen Ausführungsform ist eine Bedienungseinrichtung an die Steuerungseinrichtung gekoppelt und an der Bedienungseinrichtung kann ein Bediener eine Höhenpositionsvorgabe und/oder eine Schneidgutdurchmesservorgabe einstellen. Dadurch lässt sich auf einfache Weise durch einen Bediener die geeignete Höhenposition erreichen.In an alternative embodiment, an operating device is coupled to the control device and on the operating device, an operator can set a height position specification and / or a Schneidgutdurchmessvorschgabe. This makes it easy to reach the appropriate height position by an operator.

Das mindestens eine Stützelement kann mechanisch oder signalwirksam mit der Höhenverstellungseinrichtung der Aufnahmeeinrichtung gekoppelt sein. Bei einer mechanischen Kopplung ist eine direkte mechanische Verbindung mit der Höhenverstellungseinrichtung vorgesehen. Beispielsweise ist eine mechanische Kopplung mit einem Antrieb der Höhenverstellungseinrichtung vorgesehen oder mit einem höhenverschieblichen Element der Höhenverstellungseinrichtung. Bei einer singalwirksamen Kopplung ist keine direkte mechanische Kopplung notwendig. Es werden Ansteuerungssignale für die Höhenverstellungseinrichtung oder daraus abgeleitete Signale benutzt, um das mindestens eine Stützelement so anzusteuern, dass die wirksame Stützfläche an der geeigneten Höhenposition liegt.The at least one support element may be mechanically or signal-effectively coupled to the height adjustment device of the receiving device. In a mechanical coupling a direct mechanical connection with the height adjustment device is provided. For example, a mechanical coupling is provided with a drive of the height adjustment device or with a height-displaceable element of the height adjustment device. With a singaleffective coupling no direct mechanical coupling is necessary. Activation signals for the height adjustment device or signals derived therefrom are used to control the at least one support element so that the effective support surface lies at the suitable height position.

Bei einem Ausführungsbeispiel weist das mindestens eine Stützelement eine höhenverschiebliche Stützfläche auf. Das Stützelement wird dann so positioniert, dass die höhenverschiebliche Stützfläche auf der gleichen Höhe wie eine Auflagefläche der Aufnahmeeinrichtung liegt.In one embodiment, the at least one support element has a height-adjustable support surface. The support element is then positioned so that the height-adjustable support surface is at the same height as a support surface of the receiving device.

Es ist dabei möglich, dass eine Höhenverstellungsrichtung der mindestens eine Stützfläche mindestens näherungsweise parallel zu einer Höhenverschiebungsrichtung der Aufnahmeeinrichtung ist. Beispielsweise ist das Stützelement als Finger ausgebildet, welcher höhenverschieblich ist. Durch die entsprechende Positionierung des Fingers lässt sich eine wirksame Stützfläche bereitstellen.It is possible that a height adjustment direction of the at least one support surface is at least approximately parallel to a height displacement direction of the receiving device. For example, the support element is designed as a finger, which is höhenverschieblich. By appropriate positioning of the finger can provide an effective support surface.

Es ist auch möglich, dass das mindestens eine Stützelement an einem Messerschutzring beweglich angeordnet ist. Der Messerschutzring bildet eine Führungseinrichtung für das Stützelement, und das Stützelement kann durch entsprechende Verschiebung an dem Messerschutzring in die für seine wirksame Stützfläche geeignete Höhenposition verschoben werden.It is also possible that the at least one support element is arranged to be movable on a knife protection ring. The knife guard ring forms a guide means for the support member, and the support member can be displaced by appropriate displacement of the blade guard ring in the appropriate for its effective support surface height position.

Es ist dann beispielsweise vorgesehen, dass das mindestens eine Stützelement über eine Gelenkeinrichtung an die Höhenverstellungseinrichtung (mechanisch) gekoppelt ist. Dadurch lässt sich automatisch die richtige Position der Stützfläche in Abhängigkeit von der Höhenposition der Aufnahmeeinrichtung einstellen.It is then provided, for example, that the at least one support element is coupled via a joint device to the height adjustment device (mechanical). As a result, the correct position of the support surface depending on the height position of the receiving device can be automatically adjusted.

Bei einem alternativen Ausführungsbeispiel ist eine Mehrzahl von Stützelementen vorgesehen, wobei unterschiedliche Stützelemente Stützflächen in unterschiedlichen Höhenpositionen relativ zum Schneidmesser aufweisen, und ein wirksames Stützelement mit einer wirksamen Stützfläche durch die Höhenposition der Aufnahmeeinrichtung relativ zum Schneidmesser bestimmt ist. Wenn eine Mehrzahl von insbesondere fingerartigen Stützelementen (Finger) vorgesehen ist, dann lässt sich eine wirksame Stützfläche dadurch realisieren, dass das geeignete Stützelement ausgewählt ist. Die anderen Stützelemente sind dann in einer nicht wirksamen Position. Dadurch ist es möglich, dass für die Bereitstellung einer wirksamen Stützfläche ein Stützelement in einem minimierten Raumbereich bewegt wird. Dadurch lässt sich die Schneidgutabstützungseinrichtung auf einfache Weise an einer Lebensmittel-Schneidemaschine unterbringen.In an alternative embodiment, a plurality of support members are provided, wherein different support members have support surfaces in different height positions relative to the cutting blade, and an effective support member having an effective support surface is determined by the height position of the receiver relative to the cutting blade. If a plurality of in particular finger-like support elements (fingers) is provided, then an effective support surface can be realized by selecting the suitable support element. The others Support elements are then in an inactive position. This makes it possible for a support element to be moved in a minimized spatial area to provide an effective support surface. As a result, the Schneidgutabstützungseinrichtung can be accommodated easily on a food slicer.

Insbesondere sind die Stützelemente zwischen mindestens einer Nichtwirkungsstellung und mindestens einer Wirkungsstellung beweglich, wobei in der mindestens einen Wirkungsstellung eine wirksame Stützfläche bereitgestellt ist. Es wird dann in Abhängigkeit von der Höhenposition der Aufnahmeeinrichtung das jeweilige Stützelement ausgewählt, welches in eine wirksame Stellung, dass heißt in die Wirkungsstellung gebracht wird. Die anderen Stützelemente stören dann den Schneidvorgang nicht.In particular, the support elements are movable between at least one non-action position and at least one action position, wherein in the at least one effective position, an effective support surface is provided. It is then selected depending on the height position of the receiving device, the respective support element, which is brought into an operative position, that is, in the effect position. The other support elements then interfere with the cutting process.

Die Stützelemente können dabei in eine Richtung quer oder parallel zu einer Höhenverstellungsrichtung der Aufnahmeeinrichtung beweglich sein, je nach Ausführungsform.The support elements may be movable in a direction transverse or parallel to a height adjustment direction of the receiving device, depending on the embodiment.

Insbesondere sind die Stützelemente parallel angeordnet. Durch Auswahl des entsprechenden Stützelements, wobei die Stützelemente in unterschiedlichen Höhenpositionen positioniert sind, lässt sich die geeignete wirksame Stützfläche bereitstellen.In particular, the support elements are arranged in parallel. By selecting the corresponding support element, wherein the support elements are positioned at different height positions, the appropriate effective support surface can be provided.

Bei einer Ausführungsform sind die Stützelemente federbeaufschlagt. Je nach Anordnung und Ausbildung einer entsprechenden Feder lässt es sich dadurch erreichen, dass Stützelemente automatisch von einer Nichtwirkungsstellung in eine Wirkungsstellung gebracht werden oder umgekehrt von einer Wirkungsstellung in eine Nichtwirkungsstellung. Bei einer vorteilhaften Ausführungsform ist die Federbeaufschlagung derart, dass, wenn keine ständige Kraft auf ein Stützelement ausgeübt wird, dieses von einer Wirkungsstellung in einer Nichtwirkungsstellung zurückkehrt. Dadurch lässt sich auf einfache Weise ein Stützelement "einfahren", damit dieses einen Schneidvorgang oder Verstellungsvorgang nicht behindert.In one embodiment, the support elements are spring loaded. Depending on the arrangement and design of a corresponding spring, it can be achieved that support elements are automatically brought from a non-action position into an action position or vice versa from an action position in a non-action position. In an advantageous embodiment, the spring loading is such that, if no permanent force is exerted on a support element, this returns from an effective position in a non-operative position. As a result, a support element can be "retracted" in a simple manner, so that it does not hinder a cutting process or adjustment process.

Insbesondere sind die Stützelemente in der mindestens einer Nichtwirkungsstellung durch eine Fixierungseinrichtung fixiert und die Lösung der Fixierung eines Stützelements ist in Abhängigkeit zu der Höhenposition der Aufnahmeeinrichtung bewirkt. Durch eine aktive Höhenverstellung der Aufnahmeeinrichtung lässt sich das geeignete Stützelement in eine Wirkungsstellung bringen. Es ist dazu ein aktiver Vorgang notwendig. Dadurch lässt sich insbesondere der Übergang von einer Nichtwirkungsstellung in eine Wirkungsstellung mit konstruktiv einfachen Mitteln realisieren. Insbesondere sind die Stützelemente in ihrer Nichtwirkungsstellung mit einer Anschlagplatte für Schneidgut fixiert. Bei einer Verstellung der Anschlagplatte auf unterschiedliche Scheibendicken werden die Stützelemente in ihrer Nichtwirkungsstellung mit verstellt und insbesondere mit der Anschlagplatte verschoben. Wird die Anschlagplatte auf eine Scheibendicke unter Null gestellt, befinden sich alle Stützelemente in dieser Position "unter Null". Das Schneidmesser ist dann komplett geschützt (abgedeckt), um vor Unfällen zu schützen.In particular, the support elements are fixed in the at least one non-action position by a fixing device and the solution of the fixation of a support element is effected in dependence on the height position of the receiving device. By an active height adjustment of the receiving device can bring the appropriate support element in an effective position. It is necessary to an active process. This makes it possible in particular to realize the transition from a non-acting position into an effective position with structurally simple means. In particular, the support elements are fixed in their non-action position with a stop plate for cutting material. In an adjustment of the stop plate to different disc thicknesses, the support elements are adjusted in their non-operative position with and in particular moved with the stop plate. If the stop plate is set to a disc thickness below zero, all support elements are in this position "below zero". The cutting blade is then completely protected (covered) to protect against accidents.

Es ist dann günstig, wenn die Höhenverstellungseinrichtung diskrete Höhenpositionen für die Aufnahmeeinrichtung vorgibt, welche durch die Höhenposition der Stützelemente vorgegeben sind. Beispielsweise sind zwei oder mehr diskrete Höhenpositionen für die Aufnahmeeinrichtung vorgesehen. Dadurch lässt sich auf einfache Weise eine Anpassung der Höhenposition der wirksamen Stützfläche an die Höhenposition einer Beaufschlagungsfläche der Aufnahmeeinrichtung erreichen.It is advantageous if the height adjustment device sets discrete height positions for the receiving device, which are predetermined by the height position of the support elements. For example, two or more discrete height positions are provided for the receiving device. As a result, an adjustment of the height position of the effective support surface to the height position of a loading surface of the receiving device can be achieved in a simple manner.

Ein Ausführungsbeispiel einer Lebensmittel-Schneidemaschine, welche in Figur 1 gezeigt und dort mit 10 bezeichnet ist, umfasst eine Basis 12, mittels welcher die Lebensmittel-Schneidemaschine 10 auf einer Unterlage aufgestellt ist. An der Basis 12 ist ein Gehäuse 14 angeordnet oder die Basis 12 ist Teil des Gehäuses 14.An embodiment of a food cutting machine, which in FIG. 1 shown and designated therein by 10, comprises a base 12, by means of which the food cutting machine 10 is placed on a base. At the base 12, a housing 14 is disposed or the base 12 is part of the housing 14th

Die Lebensmittel-Schneidemaschine 10 umfasst ein Schneidmesser 16, welches in einer Rotationsbewegung um eine Rotationsachse 18 angetrieben ist. Der Antrieb, welcher in Figur 1 nicht gezeigt ist, ist in dem Gehäuse 14 angeordnet.The food slicing machine 10 includes a cutting blade 16 which is driven in a rotational movement about a rotation axis 18. The drive, which in FIG. 1 is not shown, is disposed in the housing 14.

Bei dem gezeigten Ausführungsbeispiel ist die Rotationsachse 18 senkrecht zur Zeichenebene.In the embodiment shown, the axis of rotation 18 is perpendicular to the plane of the drawing.

Das Schneidmesser 16 ist insbesondere ein Kreismesser.The cutting blade 16 is in particular a circular blade.

An dem Gehäuse 14 ist ein Schlitten 20 angeordnet. An dem Schlitten 20 wiederum ist eine Aufnahmeeinrichtung 22 für Schneidgut 24 positioniert.On the housing 14, a carriage 20 is arranged. On the carriage 20, in turn, a receiving device 22 for cutting material 24 is positioned.

Der Schlitten 20 ist in einer Richtung/Gegenrichtung 26 relativ zu dem Schneidmesser 16 verschieblich. Der Schlitten 20 kann dabei in seiner Verschiebungsbewegung von Hand (durch einen Bediener) angetrieben sein, motorisch angetrieben sein oder es kann eine motorische Unterstützung von Handbetrieb vorgesehen sein.The carriage 20 is slidable in a direction / opposite direction 26 relative to the cutting blade 16. The carriage 20 can be driven in its displacement movement by hand (by an operator), be driven by a motor or it may be provided a motor support manual operation.

Die Richtung/Gegenrichtung 26 liegt insbesondere senkrecht zu der Rotationsachse 18 des Schneidmessers 16.The direction / opposite direction 26 is in particular perpendicular to the axis of rotation 18 of the cutting blade 16.

An dem Gehäuse 14 ist eine Anschlagplatte 28 angeordnet, deren Abstand in einer Richtung parallel zur Rotationsachse 18 (quer zur Richtung/ Gegenrichtung 26) relativ zum Schneidmesser 16 und damit zu einer Schneidebene einstellbar ist. Über die Einstellung der Position der Anschlagplatte 28 relativ zu dem Schneidmesser 16 lässt sich eine Schnittdicke von Lebensmittelscheiben, die von dem Schneidgut 24 abgeschnitten werden, einstellen.On the housing 14, a stop plate 28 is arranged, whose distance in a direction parallel to the axis of rotation 18 (transverse to the direction / opposite direction 26) is adjustable relative to the cutting blade 16 and thus to a cutting plane. By adjusting the position of the stopper plate 28 relative to the cutting blade 16, a slice thickness of food slices cut from the slicing material 24 can be adjusted.

Die Lebensmittel-Schneidemaschine 10 umfasst eine Höhenverstellungseinrichtung 30, durch welche Höhenpositionen der Aufnahmeeinrichtung 22 relativ zu dem Gehäuse 14 und damit auch zu dem Schneidmesser 16 einstellbar sind. In Figur 1 sind zwei unterschiedliche Höhenpositionen 32a und 32b angedeutet.The food slicing machine 10 comprises a height adjustment device 30, by means of which height positions of the receiving device 22 relative to the housing 14 and thus also to the cutting blade 16 are adjustable. In FIG. 1 two different height positions 32a and 32b are indicated.

Die Höhenverstellungseinrichtung 30 ist beispielsweise mindestens mit Teilkomponenten an dem Schlitten 20 angeordnet und mit diesem mitführbar.The height adjustment device 30 is arranged, for example, at least with subcomponents on the carriage 20 and mitführbar with this.

Eine Höhenverschiebung der Aufnahmeeinrichtung 22 an dem Schlitten 20 ist vorzugsweise angetrieben. Beispielsweise ist dazu ein Elektromotor, ein pneumatischer Antrieb oder ein hydraulischer Antrieb vorgesehen.A height displacement of the receiving device 22 on the carriage 20 is preferably driven. For example, an electric motor, a pneumatic drive or a hydraulic drive is provided for this purpose.

Es ist dabei grundsätzlich möglich, dass der entsprechende Antrieb in dem Gehäuse 14 angeordnet ist und nicht mit dem Schlitten 20 bewegt wird. Es ist dann eine entsprechende Übertragungseinrichtung vorgesehen, welche die Antriebskraft oder das Antriebsdrehmoment des Antriebs auf die Aufnahmeeinrichtung 22 überträgt, um die Höhenposition einzustellen (und festzustellen). Beispielsweise ist es vorgesehen, dass der Schlitten 20 relativ zu dem Gehäuse 14 eine ausgezeichnete Stellung aufweist, in welcher die Übertragungseinrichtung wirksam sein kann, um eine Höhenposition der Aufnahmeeinrichtung 22 einstellen zu können.It is basically possible that the corresponding drive is arranged in the housing 14 and is not moved by the carriage 20. There is then provided a corresponding transmission means which transmits the driving force or driving torque of the drive to the receiving means 22 for adjusting (and detecting) the height position. For example, it is provided that the carriage 20 has an excellent position relative to the housing 14, in which the transmission device can be effective in order to adjust a height position of the receiving device 22.

Es ist auch möglich, dass die Höhenverstellungseinrichtung 30 als Ganzes mit dem Schlitten 20 verschoben wird.It is also possible that the height adjustment device 30 is displaced as a whole with the carriage 20.

Über die Höhenverstellungseinrichtung 30 lässt sich das Schneidgut 24 eines bestimmten Durchmessers in eine optimale Schneidposition relativ zu dem Schneidmesser 16 bringen. Beispielsweise kann Schneidgut 24 mit kleinerem Durchmesser bezogen auf die vertikale Richtung nach oben verschoben werden, um einen Angriff des Schneidmessers 16 näher an einem Scheitelpunkt zu ermöglichen.About the height adjustment device 30 can be the cutting material 24 of a certain diameter in an optimal cutting position relative to the Bring cutting knife 16. For example, cutting material 24 of smaller diameter may be displaced upwardly with respect to the vertical direction to allow engagement of the cutting blade 16 closer to a vertex.

Die Lebensmittel-Schneidemaschine 10 ist insbesondere so ausgebildet, dass das Schneidmesser 16 translatorisch feststeht. Durch den Schlitten 20 wird Schneidgut 24 relativ zu dem Schneidmesser 16 verschoben. Durch die Höheneinstellbarkeit der Aufnahmeeinrichtung 22 lässt sich erreichen, dass das Schneidmesser 16 in Schneidgut 24 eindringt, wenn ein Geschwindigkeitsvektor 34 des rotierenden Schneidmessers im Wesentlichen senkrecht zu einer Auflagefläche 36 der Aufnahmeeinrichtung 22 ist. Ein entsprechend positioniertes Schneidgut 24 ist in Figur 1 mit dem Bezugszeichen 38 angedeutet. Mit dem Bezugszeichen 40 ist Schneidgut 24 angedeutet, bei dem dies nicht der Fall ist. Hier ist der Geschwindigkeitsvektor schräg zu der Auflagefläche 36 orientiert. Im letzteren Falle entstehen Zerrkräfte auf das Schneidgut 24, die die Schnittqualität beeinflussen können; die Zerrkräfte können das Schneidgut 40 "anreißen".The food cutting machine 10 is in particular designed so that the cutting blade 16 is translationally fixed. By the carriage 20 sliced 24 is moved relative to the cutting blade 16. Due to the height adjustability of the receiving device 22, it can be achieved that the cutting blade 16 penetrates cutting material 24 when a speed vector 34 of the rotating cutting blade is substantially perpendicular to a bearing surface 36 of the receiving device 22. A correspondingly positioned cutting material 24 is in FIG. 1 indicated by the reference numeral 38. By the reference numeral 40 cutting material 24 is indicated, in which this is not the case. Here, the velocity vector is oriented obliquely to the support surface 36. In the latter case, tearing forces occur on the cut material 24, which can influence the quality of cut; the tearing forces can "rip" the material to be cut 40.

Durch die Höhenverstellungseinrichtung 30 ist eine Anpassung in Abhängigkeit des Schneidgutdurchmessers möglich.By the height adjustment device 30 is an adaptation depending on the Schneidgutdurchmessers possible.

Es kann vorgesehen sein, dass die Aufnahmeeinrichtung 22 eine Mehrzahl von Höhenpositionen aufweist, wobei ein kontinuierlicher Übergang möglich ist. Es ist grundsätzlich auch möglich, dass die Aufnahmeeinrichtung 22 diskrete Höhenpositionen 32a, 32b und beispielsweise zwei oder mehr diskrete Höhenpositionen aufweist.It can be provided that the receiving device 22 has a plurality of height positions, wherein a continuous transition is possible. In principle, it is also possible that the receiving device 22 has discrete height positions 32a, 32b and, for example, two or more discrete height positions.

Die Lebensmittel-Schneidemaschine 10 umfasst eine Steuerungseinrichtung 42, durch welche die Höhenverstellungseinrichtung 30 derart einstellbar ist, dass eine geeignete Höhenposition eingestellt und auch über eine Fixierungseinrichtung festgestellt wird.The food slicing machine 10 comprises a control device 42, by means of which the height adjustment device 30 can be adjusted in such a way that a suitable height position is set and also determined via a fixing device.

Es ist dabei grundsätzlich möglich, dass über eine Bedienungseinrichtung 44 Vorgaben eingestellt werden können, wobei die Steuerungseinrichtung 42 dann entsprechend die Höhenverstellungseinrichtung 30 ansteuert. Beispielsweise kann über die Bedienungseinrichtung 44 eine Höhenpositionsvorgabe gemacht werden oder eine Vorgabe für den Schneidgutdurchmesser von zu schneidendem Schneidgut 24 gemacht werden.In this case, it is fundamentally possible that settings can be set via an operating device 44, with the control device 42 then correspondingly actuating the height adjustment device 30. For example, a height position specification can be made via the operating device 44 or a default can be made for the cutting material diameter of cutting material 24 to be cut.

Es ist grundsätzlich auch möglich, dass eine Sensoreinrichtung 46 vorgesehen ist, über welche ein Schneidgutdurchmesser detektierbar ist. Beispielsweise ist die Sensoreinrichtung 46 eine optische Einrichtung, welche den Durchmesser von aufgelegtem Schneidgut misst.In principle, it is also possible that a sensor device 46 is provided, via which a cutting material diameter can be detected. By way of example, the sensor device 46 is an optical device which measures the diameter of the material to be cut on top.

Es ist auch möglich, dass die Sensoreinrichtung 46 eine mechanische Einrichtung ist. Diese umfasst beispielsweise eine Leiste, welche an auf der Auflagefläche 36 aufgelegtes Schneidgut 24 anzulegen ist. Aus der Position der Leiste ist dann der Schneidgutdurchmesser ermittelbar.It is also possible that the sensor device 46 is a mechanical device. This comprises, for example, a strip which is to be applied to the support surface 36 placed on the cutting material 24. From the position of the bar then the Schneidgutdurchmesser is determined.

Es ist grundsätzlich auch möglich, dass ein Schneidgutdurchmesser aus dem aktuellen Drehmoment, welches beim Eindringen des Schneidmessers 16 in das Schneidgut 24 gemessen wird, ermittelt wird.In principle, it is also possible for a cutting material diameter to be determined from the current torque, which is measured when the cutting blade 16 penetrates the cutting material 24.

Beim Vorsehen einer Sensoreinrichtung 46 lässt sich in Abhängigkeit von dem Ergebnis der Detektion des Schneidgutdurchmessers die geeignete Höhenposition der Aufnahmeeinrichtung 22 automatisch einstellen.When a sensor device 46 is provided, the suitable height position of the receiving device 22 can be set automatically as a function of the result of the detection of the cutting material diameter.

Eine Höhenverstellrichtung 48 der Höhenverstelleinrichtung 30 liegt quer und insbesondere senkrecht zu der Rotationsachse 18 und quer und insbesondere senkrecht zu der Richtung/Gegenrichtung 26 der Schlittenverschieblichkeit.A height adjustment direction 48 of the height adjustment device 30 is transverse and in particular perpendicular to the axis of rotation 18 and transversely and in particular perpendicular to the direction / opposite direction 26 of the carriage displaceability.

Schnittgutscheiben können von dem Schneidmesser 16 über eine Transporteinrichtung 50 wie beispielsweise eine Kettenrahmeneinrichtung abtransportiert werden (Figur 2).Sliced slices can be removed from the cutting blade 16 via a transport device 50 such as a chain frame device ( FIG. 2 ).

Um das Schneidmesser 16 ist ein Messerschutzring 52 angeordnet (Figur 3), welcher das Schneidmesser 16 bis auf einen Schneidbereich 54 abdeckt.To the cutting blade 16, a knife protection ring 52 is arranged ( FIG. 3 ), which covers the cutting blade 16 except for a cutting area 54.

Die Lebensmittel-Schneidemaschine 10 umfasst eine Schneidgutabstützungseinrichtung 56, durch welche Schneidgut beim Schneiden abstützbar. Die Schneidgutabstützungseinrichtung 56 umfasst eine Stützfläche 58, welche ein Gegenlager bei einem Schneidvorgang definiert. Die Stützfläche 58 ist dabei zwischen dem Schneidmesser 16 beziehungsweise der Anschlagplatte 28 und dem Schlitten 20 angeordnet. Sie ist derart angeordnet, dass die Beweglichkeit des Schlittens 20 in der Richtung/Gegenrichtung 26 ermöglicht ist. Die Einstellbarkeit der Anschlagplatte 28 relativ zu dem Schneidmesser 16 ist ebenfalls ermöglicht.The food cutting machine 10 comprises a Schneidgutabstützungseinrichtung 56, supported by which cutting material during cutting. The Schneidgutabstützungseinrichtung 56 includes a support surface 58, which defines an abutment in a cutting operation. The support surface 58 is arranged between the cutting blade 16 and the stop plate 28 and the carriage 20. It is arranged such that the mobility of the carriage 20 in the direction / opposite direction 26 is made possible. The adjustability of the stop plate 28 relative to the cutting blade 16 is also possible.

Die Schneidgutabstützungseinrichtung 56 umfasst in einem ersten Ausführungsbeispiel, das in Figur 3 schematisch gezeigt ist, ein Stützelement 60, an welchem die Stützfläche 58 gebildet ist. Das Stützelement 60 ist höhenverschieblich parallel zu der Höhenverstellrichtung 48.The Schneidgutabstützungseinrichtung 56 comprises in a first embodiment, the in FIG. 3 is shown schematically, a support member 60 on which the support surface 58 is formed. The support member 60 is height-displaceable parallel to the height adjustment 48th

Es ist grundsätzlich möglich, dass das Stützelement 60 quer zu Richtung 48 an der Basis 12 beziehungsweise dem Gehäuse 14 verschieblich gehalten ist, um die Verschieblichkeit der Anschlagplatte28 zu ermöglichen. Das Stützelement 60 ist an die Höhenverstelleinrichtung 30 gekoppelt. Diese Kopplung kann eine mechanische Kopplung sein oder auch eine signalwirksame Kopplung. Im letzteren Falle werden durch die Steuerungseinrichtung 42 einem Antrieb 62 (wie beispielsweise einem Elektromotor) Signale bereitgestellt, welche eine Höhenverstellung des Stützelements 60 angepasst an die Höhenposition der Aufnahmeeinrichtung 22 bewirken. Durch die Höhenverstellbarkeit der Aufnahmeinrichtung 22 muss die wirksame Stützfläche 58 an die Höhenposition der Aufnahmeeinrichtung 22 angepasst werden. Durch das höhenverschiebliche Stützelement 60 ist dies möglich. Durch eine mechanische oder singalwirksame Kopplung erfolgt dabei die Höheneinstellung der Stützfläche 58 in Abhängigkeit von der Höhenposition der Aufnahmeeinrichtung 22, so dass automatisch die richtige Höhenposition der Stützfläche 58 erreicht ist.It is in principle possible for the support element 60 to be held displaceably transversely to the direction 48 on the base 12 or the housing 14 in order to enable the slidability of the stop plate 28. The support element 60 is coupled to the height adjustment device 30. This coupling can be a mechanical coupling or a signal-effective coupling. In the latter case, signals are provided by the control device 42 to a drive 62 (such as an electric motor), for example, which effect a height adjustment of the support element 60 adapted to the height position of the receiving device 22. Due to the height adjustability of the receiving device 22, the effective support surface 58 must be adapted to the height position of the receiving device 22. By the height-adjustable support element 60, this is possible. By a mechanical or singaleffksame coupling thereby the height adjustment of the support surface 58 in dependence on the height position of the receiving device 22, so that automatically the correct height position of the support surface 58 is reached.

Bei dem Stützelement 60 erfolgt die Anpassung der Stützfläche 58 an die Höhenposition der Aufnahmeeinrichtung 22 durch Höhenverstellung der Stützfläche 58 in der Richtung 48.In the support member 60, the adjustment of the support surface 58 to the height position of the receiving device 22 by height adjustment of the support surface 58 in the direction 48 takes place.

Beim zweiten Ausführungsbeispiel einer Schneidgutabstützungseinrichtung, welches in den Figuren 4 bis 7 gezeigt und dort mit 64 bezeichnet ist, sind eine Mehrzahl von Stützelementen 66a bis 66d vorgesehen. Die Stützelemente 66a bis 66d sind an einer Halteeinrichtung 68 angeordnet. Die Halteeinrichtung 68 ist an der Anschlagplatte 28 fixiert und mit dieser verschieblich, oder sie ist an der Basis 12 fixiert und kann dabei feststehend sein oder in einer Richtung parallel zur Verschiebungsrichtung der Anschlagplatte 28 verschieblich sein.In the second embodiment of a Schneidgutabstützungseinrichtung, which in the FIGS. 4 to 7 shown and designated 64 therein, a plurality of support members 66a to 66d are provided. The support elements 66a to 66d are arranged on a holding device 68. The holding device 68 is fixed to the stop plate 28 and slidably with this, or it is fixed to the base 12 and may be stationary or be displaceable in a direction parallel to the direction of displacement of the stop plate 28.

Die Stützelemente 66a bis 66d sind parallel ausgerichtet mit einer Längsachse 70, welche quer und insbesondere senkrecht zu einer Schneidebene 72 ist. Die Längsachse 70 ist insbesondere parallel zu einer Verschiebungsrichtung der Anschlagplatte 28.The support elements 66a to 66d are aligned in parallel with a longitudinal axis 70 which is transverse and in particular perpendicular to a cutting plane 72. The longitudinal axis 70 is in particular parallel to a direction of displacement of the stop plate 28.

Die Halteeinrichtung 68 weist eine Mehrzahl von Aufnahmen 74 auf, wobei die Anzahl der Aufnahmen 74 die Anzahl der Stützelemente 66a bis 66d entspricht und die jeweiligen Stützelemente 66a bis 66d in der eigenen Aufnahme 74 angeordnet sind.The holding device 68 has a plurality of receptacles 74, wherein the number of receptacles 74 corresponds to the number of support elements 66a to 66d and the respective support elements 66a to 66d are arranged in the own receptacle 74.

Die Stützelemente 66a bis 66d sind in ihren Aufnahmen 74 verschieblich gelagert mit einer Verschiebungsrichtung parallel zur Längsachse 70.The support elements 66a to 66d are slidably mounted in their receptacles 74 with a displacement direction parallel to the longitudinal axis 70th

Die Stützelemente 66a bis 66d weisen jeweilige Stützflächen 76a bis 76d auf, welche an einer der Basis 12 abgewandten Seite der jeweiligen Stützelemente 66a bis 66d angeordnet sind. Beispielsweise sind die Stützflächen 76a bis 76d ebene Flächen. Es ist aber grundsätzlich auch möglich, dass diese Stützflächen 76a bis 76d jeweils gekrümmte Flächen sind.The support elements 66a to 66d have respective support surfaces 76a to 76d which are arranged on a side of the respective support elements 66a to 66d facing away from the base 12. For example, the support surfaces 76a to 76d are flat surfaces. But it is also possible in principle that these support surfaces 76a to 76d are curved surfaces.

Die Stützelemente 66a bis 66d weisen jeweils einen Stützflächenbereich 78 auf und einen Haltebereich 80. Der Haltebereich 80 ist insbesondere als Stift 82 ausgebildet. Um den Stift 82 ist eine Feder 84 angeordnet. Die Feder 84 stützt sich mit einem ersten Ende 86a an einer Aufnahmewand 88 ab. Mit einem zweiten Ende 86b stützt sie sich an einem Ringelement 90 ab, welches in einem mittleren Bereich fest an dem Stift 82 angeordnet ist. Die Feder 84 ist bestrebt, das jeweilige Stützelement in der Halteeinrichtung 68 zu verschieben und so zu halten, dass die zugeordnete Stützfläche nicht über eine Vorderebene 92 der Halteeinrichtung 68 hinausragt. Sie ist dadurch Teil einer Fixierungseinrichtung 93 für das jeweilige Stützelement. Die Vorderebene 92 ist gleichzeitig zumindest teilweise eine Anlagefläche für Schneidgut an die Anschlagplatte 28.The support elements 66a to 66d each have a support surface area 78 and a holding area 80. The holding area 80 is designed in particular as a pin 82. To the pin 82, a spring 84 is arranged. The spring 84 is supported by a first end 86a on a receiving wall 88. With a second end 86b, it is supported on a ring element 90 which is fixedly arranged on the pin 82 in a middle region. The spring 84 endeavors to displace the respective support element in the holding device 68 and to hold it so that the associated support surface does not protrude beyond a front plane 92 of the holding device 68. As a result, it is part of a fixing device 93 for the respective support element. The front plane 92 is at the same time at least partially a contact surface for cutting material to the stop plate 28th

Die Stützelemente 66a bis 66d weisen eine Nichtwirkungsstellung 94 auf, in welcher sie durch die jeweilige Feder 84 gehalten (fixiert) werden und in welcher die zugeordneten Stützelemente 66a bis 66d nicht über die Vorderebene 92 hinaus ragen. Der Haltebereich 80 ragt in dieser Stellung mit einem Teilbereich 96 über eine der Vorderebene 92 gegenüberliegende Rückseite 98 der Halteeinrichtung hinaus. Dazu ist an der Halteeinrichtung 68 im Bereich der Rückseite 98 jeweils eine Ausnehmung 100 angeordnet, durch welche der Stift 82 durchtauchen kann.The support elements 66a to 66d have a non-action position 94 in which they are held (fixed) by the respective spring 84 and in which the associated support elements 66a to 66d do not project beyond the front plane 92. The holding region 80 protrudes in this position with a portion 96 beyond a rear plane 98 of the holding device opposite the front plane 92. For this purpose, in each case a recess 100 is arranged on the holding device 68 in the region of the rear side 98, through which the pin 82 can penetrate.

An die Höhenverstellungseinrichtung 30 ist ein Beaufschlagungselement 102 gekoppelt, welches auf einen Stift 82 wirken kann und zwar jeweils nur auf einem einzigen Stift 82. Das Beaufschlagungselement 102 ist mit der Aufnahmeeinrichtung 22 höhenverschieblich. Die Höhenposition der Aufnahmeeinrichtung 22 definiert eine Höhenposition eines Beaufschlagungsbereichs 104 des Beaufschlagungselements 102.To the height adjustment device 30, a biasing member 102 is coupled, which can act on a pin 82, in each case only on a single pin 82. The biasing member 102 is höhenverschieblich with the receiving device 22. The height position of the receiver 22 defines a height position of an urging portion 104 of the biasing member 102.

Je nach Höhenstellung des Beaufschlagungsbereichs 104 wirkt dieser Beaufschlagungsbereich 104 auf den Stift 82 eines bestimmten Stützelements 66a bis 66d und bringt diesen in eine Wirkungsstellung 106. In Figur 7 ist diese Wirkungsstellung 106 für das Stützelement 66b gezeigt. Der Beaufschlagungsbereich 104 drückt den Stift 82 entgegen der Kraft der entsprechenden Feder 84 und schiebt dabei die Stützfläche 76b über die Vorderebene 92 hinaus. Dadurch wird die Stützfläche 76b zu einer wirksamen Stützfläche, auf der Schneidgut beim Schneiden auflegbar ist. Die Stützfläche 76b liegt dabei mindestens näherungsweise auf einer gleichen Höhe (exakt auf der gleichen Höhe oder nur wenig darunter) wie die Auflagefläche 36 der Aufnahmeeinrichtung 22.Depending on the height position of the loading area 104, this loading area 104 acts on the pin 82 of a specific support element 66a to 66d and brings it into an operative position 106 FIG. 7 this effect position 106 is shown for the support member 66b. The loading area 104 pushes the pin 82 against the force of the corresponding spring 84, thereby pushing the support surface 76b beyond the front plane 92. As a result, the support surface 76b becomes an effective support surface on which cutting material can be placed when cutting. The support surface 76b is at least approximately at a same height (exactly at the same height or only slightly below) as the support surface 36 of the receiving device 22nd

Es ist dabei vorzugsweise vorgesehen, dass die Stifte 82 an ihrer Oberfläche eine entsprechende Führungskante aufweisen, die bewirkt, dass der Beaufschlagungsbereich 104 an einem Stift 82 angreifen kann und diesen durch Höhenverschiebung entgegen der Kraftwirkung der Feder 84 in die Wirkungsstellung 106 verschieben kann. Sobald der Beaufschlagungsbereich 104 nicht mehr auf den entsprechenden Stift 82 wirkt, kehrt das zugeordnete Stützelement aufgrund der Federwirkung der Feder 84 in die Nichtwirkungsstellung 94 zurück.It is preferably provided that the pins 82 have on their surface a corresponding leading edge, which causes the Beaufschlagungsbereich 104 can engage a pin 82 and this can move by height displacement against the force of the spring 84 in the action position 106. As soon as the loading region 104 no longer acts on the corresponding pin 82, the associated support element returns to the non-action position 94 due to the spring action of the spring 84.

Damit die Höhenverschiebung ausgeführt werden kann, muss die Anschlagplatte 28 zuvor auf eine Position unter Null gestellt worden sein. In dieser Position liegt die Anschlagplatte 28 vor dem Schneidmesser 16. Nach der Höhenverschiebung des Beaufschlagungsbereichs 104 wird dann die Anschlagplatte 28 verstellt. Dabei wird eine bestimmte Scheibendicke für die zu schneidenden Lebensmittel eingestellt. Dadurch wird auch automatisch der Stift 82 betätigt.In order for the height shift can be performed, the stop plate 28 must have been previously set to a position below zero. In this position, the stop plate 28 is located in front of the cutting blade 16. After the height displacement of the loading region 104, the stop plate 28 is then adjusted. In this case, a specific slice thickness is set for the food to be cut. As a result, the pin 82 is automatically actuated.

Es kann insbesondere vorgesehen sein, dass die Anschlagplatte 28 automatisch motorisch verstellt wird, wenn zur automatischen Höhenverstellung die Anschlagplatte 28 noch auf Position "unter Null" gestellt ist. Es ist dann kein manueller Drehknopf für eine Scheibendickeneinstellung notwendig.It can be provided in particular that the stop plate 28 is automatically adjusted by motor when the stop plate 28 is still set to position "below zero" for automatic height adjustment. There is then no manual knob for a disc thickness adjustment necessary.

Die Aufnahmeeinrichtung 22 weist bei diesem Ausführungsbeispiel diskrete Höhenpositionen auf, wobei die Anzahl der Höhenpositionen durch die Anzahl der Stützelemente 66a bis 66d vorgegeben ist. Bei dem gezeigten Ausführungsbeispiel sind vier Stützelemente 66a bis 66d vorhanden, so dass es vier diskrete Höhenpositionen für die Aufnahmeeinrichtung 22 gibt. Diese Höhenpositionen sind dabei an die Höhenpositionen der Stützelemente 66a bis 66d an der Halteeinrichtung 68 angepasst, sodass in der jeweiligen Höhenposition die relevante Stützfläche 76a bis 76d auf der gleichen Höhe wie die Auflagefläche 36 in der Aufnahmeeinrichtung 22 liegt.The receiving device 22 has discrete height positions in this embodiment, wherein the number of height positions is predetermined by the number of support members 66a to 66d. In the embodiment shown There are four support members 66a to 66d, so that there are four discrete height positions for the receiver 22. These height positions are adapted to the height positions of the support elements 66a to 66d on the holding device 68, so that in the respective height position, the relevant support surface 76a to 76d is at the same height as the support surface 36 in the receiving device 22.

Das Beaufschlagungselement 102 kann mechanisch oder signalwirksam an die Höhenverstellungseinrichtung 30 angekoppelt sein. Beispielsweise gibt die Steuerungseinrichtung 42 Signale an die Höhenverstellungseinrichtung 30 und an das Beaufschlagungselement 102, um eine synchrone Höheneinstellung zu erreichen.The biasing element 102 may be mechanically or signal-effectively coupled to the height adjustment device 30. For example, the controller 42 signals the height adjustment device 30 and the biasing member 102 to achieve synchronous height adjustment.

Die Auswahl des relevanten Stützelements 66a bis 66b erfolgt automatisch in Abhängigkeit von der jeweiligen Höhenposition der Aufnahmeeinrichtung 22.The selection of the relevant support element 66a to 66b takes place automatically as a function of the respective height position of the receiving device 22.

Bei einem weitern Ausführungsbeispiel einer Schneidgutabstützungseinrichtung, welche in den Figuren 8 und 9 schematisch gezeigt ist, umfasst die Schneidgutabstützungseinrichtung eine Mehrzahl von Stützelementen 108a, 108b, 108c, 108d, welche quer und insbesondere senkrecht zu der Richtung/ Gegenrichtung 26 und zu der Drehachse 18 angeordnet sind. Beispielsweise sind die Stützelemente 108a usw. in vertikaler Richtung orientiert.In a further embodiment of a Schneidgutabstützungseinrichtung, which in the FIGS. 8 and 9 is schematically shown, the Schneidgutabstützungseinrichtung comprises a plurality of support elements 108 a, 108 b, 108 c, 108 d, which are arranged transversely and in particular perpendicular to the direction / opposite direction 26 and to the axis of rotation 18. For example, the support members 108a, etc. are oriented in the vertical direction.

Sie weisen jeweilige Stützflächen 110a bis 110d auf. Die Stützelemente 108a bis 108d sind insbesondere parallel angeordnet und parallel zur Höhenverstellungsrichtung 48 beweglich. Die Verschieblichkeit und Fixierung kann dabei grundsätzlich auf die gleiche Weise erfolgen wie bei den Stützelementen 66a bis 66d.They have respective support surfaces 110a to 110d. The support elements 108a to 108d are arranged in particular parallel and movable parallel to the height adjustment direction 48. The mobility and fixation can basically take place in the same way as in the support elements 66a to 66d.

Je nach Höhenposition der Aufnahmeeinrichtung 22 wird das relevante Stützelement 108a, 108b, 108c oder 108d ausgefahren, um die entsprechende Stützfläche und Auflagefläche 36 auf der gleichen Höhe zu halten.Depending on the height position of the receiving device 22, the relevant support element 108a, 108b, 108c or 108d is extended to keep the corresponding support surface and bearing surface 36 at the same height.

Bei einem vierten Ausführungsbeispiel einer Schneidgutabstützungseinrichtung, welche in den Figuren 10(a) bis 10(c) gezeigt ist, ist an dem Messerschutzring 52 ein Stützelement 112 verschieblich angeordnet. Dieses Stützelement 112 weist eine Stützfläche 114 auf. Der Messerschutzring 52 stellt eine Verschiebungsführung für das Stützelement 112 bereit. Über eine Gelenkeinrichtung 116 ist dieses Stützelement an die Höhenverstellungseinrichtung 30 mechanisch gekoppelt. In Abhängigkeit der Höhenposition der Aufnahmeeinrichtung 22 wird die Verschiebungsstellung des Stützelements 112 an dem Messerschutzring und damit auch die Höhe der Stützfläche 114 eingestellt, um insbesondere zu erreichen, dass die Stützfläche 114 im Wesentlichen auf der gleichen Höhe wie die Auflagefläche 36 beim Schneiden liegt, und um damit eine effektive Abstützung beim Schneiden zu erhalten.In a fourth embodiment of a Schneidgutabstützungseinrichtung, which in the FIGS. 10 (a) to 10 (c) is shown, a support member 112 is slidably disposed on the blade protection ring 52. This support element 112 has a support surface 114. The knife guard ring 52 provides a displacement guide for the support member 112. Via a hinge device 116, this support element is mechanically coupled to the height adjustment device 30. Depending on the height position of the receiving device 22, the displacement position of the support member 112 on the blade guard ring and thus the height of the support surface 114 is set to achieve in particular that the support surface 114 is substantially at the same height as the support surface 36 when cutting, and so as to obtain an effective support during cutting.

Die Gelenkeinrichtung 116 umfasst beispielsweise einen Hebel 118, welcher gelenkig angelenkt ist an das Stützelement 112. Der Hebel 118 lässt sich durch die Höhenverstellungseinrichtung 30 in eine Position 120 um einen Drehpunkt 122 schwenken. Die Position 120 ist in Figur 10(a) in nicht durchgezogenen Linien angedeutet. Über einen kontinuierlichen Schwenkwinkel sind kontinuierliche anpassbare Höhen des Stützelements 112 einstellbar, wobei die Ankopplung an die Höhenverstellungseinrichtung 30 den Schwenkwinkel bestimmt.The articulation device 116 comprises, for example, a lever 118, which is articulated to the support element 112. The lever 118 can be pivoted by the height adjustment device 30 into a position 120 about a pivot point 122. Position 120 is in Figure 10 (a) indicated in non-solid lines. Continuously adjustable heights of the support member 112 are adjustable via a continuous pivoting angle, wherein the coupling to the height adjustment device 30 determines the pivoting angle.

Bei der erfindungsgemäßen Lösung ist die Schneidgutabstützungseinrichtung 56 an die Höhenverstellungseinrichtung 30 angekoppelt. Bei der Einstellung einer definierten Höhenposition der Aufnahmeeinrichtung 22 für das Schneidgut 24 wird automatisch die richtige Höhe für die wirksame Stützfläche eingestellt, um so unabhängig von der Höhenposition der Aufnahmeeinrichtung 22 eine sichere Schneidgutabstützung beim Schneiden zu erhalten.In the solution according to the invention, the Schneidgutabstützungseinrichtung 56 is coupled to the height adjustment device 30. When setting a defined height position of the receiving device 22 for the cutting material 24, the correct height for the effective support surface is automatically adjusted so as to obtain regardless of the height position of the receiving device 22 a secure Schneidgutabstützung when cutting.

Es ist dadurch möglich, indem die Höhenposition angepasst an den Schneidgutdurchmesser eingestellt wird, einen Schneidvorgang mit minimalen Zerrkräften zu realisieren. Es erfolgt dabei eine optimierte Schneidgutabstützung.It is thereby possible, by adjusting the height position adapted to the Schneidgutdurchmesser to realize a cutting operation with minimal distortion forces. There is an optimized Schneidgutabstützung.
