Aufgabe der Erfindung ist es, eine Schneidemaschine der eingangs genannten Art zu verbessern und insbesondere eine Schneidemaschine vorzuschlagen, die auch nicht gefrorenen Fisch in guter Scheibenqualität schneidet.The object of the invention is to improve a cutting machine of the type mentioned at the outset and in particular to propose a cutting machine which also cuts non-frozen fish in good slice quality.

Diese Aufgabe wird durch eine Schneidemaschine nach Anspruch 1 gelöst.This task is solved by a cutting machine according to claim 1.

Erfindungsgemäß wird eine Schneidemaschine zum Abtrennen von Scheiben von insbesondere breitem dünnem Schneidgut, insbesondere Fisch vorgeschlagen. Dabei handelt es sich zum Beispiel um Lachsfilets, die eine längliche Ausdehnung haben und eine gewisse Breite. Die Höhe beträgt nur einige Zentimeter. Die Schneidemaschine umfasst ein Maschinengehäuse. Die Schneidemaschine umfasst einen Antriebsmotor und ein von diesem in einer Schneidebene rotierend angetriebenes Schneidmesser zum Abschneiden von Scheiben. In diesem Zusammenhang ist der Ausdruck Scheibe nicht als ein Körper mit runder Fläche zu verstehen, sondern als ein Körper mit einer Ausdehnung, die durch das Schneiden in einem spitzen Winkel durch das breite dünne Schneidgut entsteht. Eine Anschlagplatte ist parallel zu der Schneidebene ausgerichtet und dient zur Einstellung einer gewünschten Scheibendicke. Die Schneidemaschine umfasst einen parallel zu der Schneidebene hin und her bewegbaren Schlitten. Der Schlitten umfasst eine Auflagefläche zum Auflegen des Schneidgutes. Die Auflagefläche ist in einem spitzen Winkel zur Schneidebene angeordnet. Die Auflagefläche ist durch mehrere parallel zueinander angeordnete und um ihre jeweiligen Achsen drehbaren Rollen gebildet.According to the invention, a cutting machine for cutting off slices of particularly wide, thin material to be cut, in particular fish, is proposed. These are, for example, salmon fillets that are elongated and have a certain width. The height is only a few centimeters. The cutting machine includes a machine housing. The cutting machine comprises a drive motor and a cutting knife which is driven in a rotating manner in a cutting plane for cutting off slices. In this context, the term disk is not to be understood as a body with a round surface, but as a body with an extension that is created by cutting at an acute angle through the wide, thin material to be cut. A stop plate is aligned parallel to the cutting plane and is used to set a desired slice thickness. The cutting machine includes a carriage that can be moved back and forth parallel to the cutting plane. The carriage includes a support surface for placing the material to be cut. The support surface is arranged at an acute angle to the cutting plane. The support surface is formed by several rollers arranged parallel to one another and rotatable about their respective axes.

In diesem Zusammenhang bilden die Tangenten der Rollen eine Ebene, die als Auflagefläche definiert ist. Die Rollen sind jedoch zueinander beabstandet, so dass das Schneidgut nicht flächig auf der Auflagefläche aufliegt, sondern vielmehr auf den einzelnen Rollen lokal aufliegt. Die Auflagepunkte der Rollen bilden eine Ebene, die die Auflagefläche im Sinne dieser Offenbarung für das Schneidgut ist.In this context, the tangents of the rollers form a plane that is defined as the support surface. However, the rollers are spaced apart from one another so that the material to be cut does not rest flat on the support surface, but rather rests locally on the individual rollers. The support points of the rollers form a plane, which is the support surface in the sense of this disclosure for the material to be cut.

Im Vergleich zum Stand der Technik hat dies den Vorteil, dass das Schneidgut leicht entlang der Auflagefläche in Richtung Schneidebene rutschen kann. Während im Stand der Technik das Schneidgut teilweise in Richtung Schneidebne geschoben werden muss, reicht bei der Ausgestaltung der Auflagefläche durch drehbare Rollen die Gravitationskraft, um das Schneidgut in Richtung Schneidebene zu ziehen. Im Stand der Technik wird oft gefrorenes Schneidgut geschnitten. Bei gefrorenem Schneidgut gleitet das Schneidgut in annehmbarer Weise über eine Auflagefläche, die zum Beispiel als Blech ausgebildet ist. Wird jedoch nicht gefrorenes Schneidgut verarbeitet, insbesondere Lachs, welches weicher und feuchter ist als gefrorenes Schneidgut und einen höheren Reibungskoeffizienten aufweist, so treten vermehrt Probleme mit dem Transport des Schneidguts in Richtung Schneidebene auf. Der Erfinder hat dieses Problem erkannt und in besonders vorteilhafter Weise durch das Anbringen von drehbaren Rollen gelöst.Compared to the prior art, this has the advantage that the material to be cut can easily slide along the support surface towards the cutting plane. While in the prior art that If the material to be cut has to be partially pushed towards the cutting plane, when the support surface is designed with rotatable rollers, the gravitational force is sufficient to pull the material to be cut towards the cutting plane. In the prior art, frozen material is often cut. When the material to be cut is frozen, the material to be cut slides in an acceptable manner over a support surface which is designed, for example, as a sheet of metal. However, if non-frozen material to be cut is processed, in particular salmon, which is softer and moister than frozen material to be cut and has a higher coefficient of friction, problems with the transport of the material to be cut towards the cutting plane increase. The inventor recognized this problem and solved it in a particularly advantageous manner by attaching rotatable rollers.

Erfindungsgemäss weisen die Rollen entlang ihrer Achsen mehrere beabstandete Ringe auf. Der Durchmesser der Ringe ist größer als der Durchmesser des Rollenkörpers. Die Ringe sind schmal und laufen an ihrer Oberseite spitz zu. In der Praxis werden die Ringe an ihrer Oberseite mit einem Radius von 0,1 mm bis 0,8 mm, vorzugsweise 0,2 mm abgerundet, da beim Herstellen einer scharfen Kante an der Oberseite ein Grat entstehen würde, der ggf. das Schneidgut verunreinigen könnte. Die Ringe haben den Vorteil, dass sie punktuell Druck auf das Schneidgut ausüben und das Schneidgute gegen verrutschen in Richtung der Achsen der Rollen absichern. Dies ist insbesondere bei nicht gefrorenem Schneidgut relevant.According to the invention, the rollers have several spaced rings along their axes. The diameter of the rings is larger than the diameter of the roller body. The rings are narrow and taper to a point at the top. In practice, the rings are rounded on their top side with a radius of 0.1 mm to 0.8 mm, preferably 0.2 mm, since producing a sharp edge would create a burr on the top side, which could potentially contaminate the material to be cut could. The rings have the advantage that they exert pressure on the material to be cut at specific points and protect the material to be cut from slipping in the direction of the axes of the rollers. This is particularly relevant for non-frozen food to be cut.

Nicht gefrorener Lachs hat zum Beispiel sehr wenig Eigenstabilität und würde sich durch den Schneidprozess und das Entlangbewegen am Schneidmesser verformen und entgegen der Bewegungsrichtung des Schlittens auf der Auflagefläche bewegen. Dadurch entstehen unregelmässige und optisch wenig ansprechende Scheiben. Im Stand der Technik wird deswegen der Lachs auf ca. -4 Grad Celsius angefroren, um ihm mehr Eigenstabilität zu verleihen und o. g. Probleme zu minimieren. Durch die Rollen mit den entsprechenden Ringen, die oben spitz zulaufen, erfährt der Lachs eine Stabilisierung in Seitwärtsrichtung. Dies gilt auch für gefrorenen Lachs. In noch ausgeprägterem Maße ist dieser Vorteil relevant für nicht gefrorenen Lachs, der wenig Eigenstabilität mitbringt. In diesem Fall dringen die ringförmigen Erhebungen leicht in den Lachs ein, ohne das Fleisch jedoch tief zu verletzen. Dieser Effekt wird insbesondere durch die Vorteilhafte Dimensionierung der Ringe im Vergleich zu der Rolle und der Dimensionierung der abgerundeten Kante erreicht.Unfrozen salmon, for example, has very little inherent stability and would deform due to the cutting process and the movement along the cutting knife and move against the direction of movement of the carriage on the support surface. This creates irregular and visually unappealing panes. In the state of the art, the salmon is therefore frozen to around -4 degrees Celsius in order to give it more inherent stability and to minimize the above-mentioned problems. The salmon is stabilized by the rolls with the corresponding rings that taper to a point at the top Sideways direction. This also applies to frozen salmon. This advantage is even more relevant for non-frozen salmon, which has little inherent stability. In this case, the ring-shaped elevations easily penetrate the salmon without deeply injuring the meat. This effect is achieved in particular by the advantageous dimensioning of the rings compared to the roller and the dimensioning of the rounded edge.

In einer Ausführungsform ist jede Rolle einstückig ausgebildet. Vorzugsweise wird die Rolle aus einem Metall-Rundstab durch Drehen hergestellt. Durch die Einstückigkeit sind keine Vertiefungen oder Schlitze in der Rolle vorhanden, so dass sich keine Bakteriennester in den Schlitzen bilden können. Das erleichtert das Erfüllen der Hygieneanforderungen im Lebensmittelbereich.In one embodiment, each roller is formed in one piece. Preferably, the roll is made from a metal round rod by turning. Because it is one piece, there are no depressions or slots in the roll, so that no bacterial nests can form in the slots. This makes it easier to meet hygiene requirements in the food sector.

In einer Ausführungsform sind die Achsen der Rollen waagrecht ausgerichtet.In one embodiment, the axes of the rollers are aligned horizontally.

In einer Ausführungsform haben die beiden am nächsten an der Schneidebene angebrachten Rollen einen ersten Abstand zueinander. Zwei benachbarte Rollen, die weiter von der Schneidebene entfernt angebracht sind, haben einen zweiten Abstand zueinander. Der erste Abstand ist geringer als der zweite Abstand. In anderen Worten heißt das, umso näher das Schneidgut über die Auflagefläche in Richtung Schneidebene kommt, umso mehr Rollen zum Abstützen des Schneidgutes sind vorhanden und bilden die Auflagefläche. Insbesondere in der Nähe der Schneidebene wirken durch den Schneidprozess die größten Kräfte in Richtung der Schlittenachse auf das Schneidgut. Das Schneidmesser bildet einen gewissen Widerstand für das Schneidgut, wenn es mit dem Schlitten parallel zur Schneidebene bewegt wird. Aus diesem Grund muss das Schneidgut in diesem Bereich am meisten stabilisiert werden. Deshalb sind in diesem Bereich die Rollen enger beabstandet. In dem Bereich weiter entfernt von der Schneidebene wirken durch den Schneidprozess keine Kräfte mehr auf das Schneidgut. Deswegen können in diesem Bereich die Rollen weiter beabstandet sein. Durch einen größeren Abstand der Rollen wird der Reibungswiderstand des Schneidguts auf der durch die Rollen gebildeten Auflagefläche verringert, wodurch das Schneidgut durch die Gravitationskraft störungsfrei entlang der Auflagefläche rutschen kann.In one embodiment, the two rollers attached closest to the cutting plane are at a first distance from one another. Two adjacent rollers that are mounted further away from the cutting plane are at a second distance from each other. The first distance is less than the second distance. In other words, the closer the material to be cut comes over the support surface towards the cutting plane, the more rollers there are to support the material to be cut and form the support surface. Particularly in the vicinity of the cutting plane, the greatest forces during the cutting process act on the material to be cut in the direction of the carriage axis. The cutting knife creates a certain resistance for the material to be cut when it is moved with the carriage parallel to the cutting plane. For this reason, the material to be cut needs to be stabilized the most in this area. That's why the rollers are more closely spaced in this area. In the area further away from the cutting plane, the cutting process no longer acts on the material to be cut. Because of this The rollers can be spaced further apart in this area. By increasing the distance between the rollers, the frictional resistance of the material to be cut on the support surface formed by the rollers is reduced, which means that the material to be cut can slide smoothly along the support surface due to the gravitational force.

In einer Ausführungsform umfasst der Schlitten einen werkzeuglos abnehmbaren Rahmen, der die Rollen trägt. Das hat den Vorteil, dass alle Rollen, die zusammen die Auflagefläche für das Schneidgut bilden und mit dem Schneidgut in direkten Kontakt kommen, zusammen aus dem Schlitten entfernt werden können und in einer Spülmaschine gereinigt werden können.In one embodiment, the carriage includes a frame that can be removed without tools and carries the rollers. This has the advantage that all the rollers, which together form the support surface for the food to be cut and come into direct contact with the food to be cut, can be removed together from the carriage and cleaned in a dishwasher.

In einer Ausführungsform umfasst der Rahmen einen in Richtung der Achsen der Rollen verstellbaren seitlichen Gegenhalter. Der seitliche Gegenhalter trägt mindestens einen waagrechten Gegenhalter. Der Abstand zwischen dem waagrechten Gegenhalter und der Auflagefläche ist einstellbar. Der waagrechte Gegenhalter dient als Kippsicherung für das Schneidgut. Ist das Schneidgut ein Lachsfilet, so ist die Dicke des Schneidgutes über seinen länglichen Verlauf unterschiedlich. Der waagrechte Gegenhalter hat keinen direkten Kontakt zum Schneidgut, er dient lediglich dazu, ein Kippen des Schneidgutes weg von der Auflagefläche zu verhindern. Das hat den Vorteil, dass das Schneidgut nicht durch den Gegenhalter an der Bewegung entlang der Auflagefläche gehindert und gebremst wird.In one embodiment, the frame comprises a lateral counter-holder that is adjustable in the direction of the axes of the rollers. The lateral counter-holder carries at least one horizontal counter-holder. The distance between the horizontal counterholder and the support surface is adjustable. The horizontal counter-holder serves to prevent the food being cut from tipping over. If the material to be cut is a salmon fillet, the thickness of the material to be cut varies along its elongated course. The horizontal counter-holder has no direct contact with the material to be cut; it only serves to prevent the material to be cut from tipping away from the support surface. This has the advantage that the material to be cut is not prevented or slowed down by the counter-holder from moving along the support surface.

In einer Ausführungsform umfasst der Schlitten einen Schlittenfuß. Der Schlitten ist verschiebbar mit einer Schlittenachse verbunden. Der Schlitten umfasst eine Schlittenplatte, die mit dem Schlittenfuß, insbesondere über einen Stützrahmen, verschraubt, vernietet, verschweißt oder verklemmt ist. In einer Ausführungsform sind Schlittenplatte, ggf. Stützrahmen und Schlittenfuß einstückig ausgebildet. Der Schlitten umfasst eine Schwenkvorrichtung, die mit der Schlittenplatte verbunden ist. In einer Ausführungsform ist die Schwenkvorrichtung werkzeuglos lösbar mit der Schlittenplatte verbunden. Der Winkel zwischen Auflagefläche und Schneidebene ist über die Schwenkvorrichtung einstellbar.In one embodiment, the carriage includes a carriage foot.

In einer Ausführungsform ist die werkzeuglos lösbare Verbindung zwischen der Schlittenplatte und der Schwenkvorrichtung durch eine werkzeuglos lösbare Verbindung zwischen dem Hydraulikzylinder und der Schlittenplatte und durch eine werkzeuglos lösbare Verbindung zwischen einer waagrechten Platte der Schwenkvorrichtung und der Schlittenplatte hergestellt.In one embodiment, the tool-free connection between the carriage plate and the pivoting device is produced by a tool-free connection between the hydraulic cylinder and the carriage plate and by a tool-free connection between a horizontal plate of the pivoting device and the carriage plate.

In einer Ausführungsform umfasst die Schlittenplatte mindestens zwei Bolzen. Die zwei Bolzen wirken mit zwei Aufnahmen in der waagrechten Platte der Schwenkvorrichtung zusammen. Die die waagrechte Platte der Schwenkvorrichtung ist auf die beiden Bolzen aufsteckbar. Die Schlittenplatte umfasst mindestens eine Schraube, die durch eine Öffnung der waagrechten Platte der Schwenkvorrichtung ragt und mit derer die waagrechte Platte der Schwenkvorrichtung an der Schlittenplatte mit einer Mutter festklemmbar ist.In one embodiment, the carriage plate includes at least two bolts. The two bolts interact with two receptacles in the horizontal plate of the swivel device. The horizontal plate of the swivel device can be attached to the two bolts. The carriage plate comprises at least one screw which protrudes through an opening in the horizontal plate of the pivoting device and with which the horizontal plate of the pivoting device can be clamped to the carriage plate with a nut.

In einer Ausführungsform ist an der Schwenkvorrichtung eine Schneidleiste befestigt. In einer Ausführungsform handelt es sich bei der Schneidleiste um eine Schneidleiste aus Kunststoff. Die Schneidleiste hat einen Abstand von 0.2 mm bis 2 mm, insbesondere 0.5 mm, zur Schneidebene.In one embodiment, a cutting bar is attached to the pivoting device. In one embodiment, the cutting strip is a plastic cutting strip. The cutting bar has a distance of 0.2 mm to 2 mm, in particular 0.5 mm, from the cutting plane.

Fig. 1 zeigt schematisch eine erfindungsgemäße Schneidemaschine 10 zum Abschneiden von Scheiben von insbesondere breitem dünnem Schneidgut wie zum Beispiel Fisch, Lachs, etc. Fig. 1 a) zeigt die Schneidemaschine 10 in einer Seitenansicht. Fig. 1 b) zeigt die Schneidemaschine 10 in einer isometrischen Ansicht, wobei zur klareren Darstellung der Schlitten etwas beabstandet und separat dargestellt ist. Die Schneidemaschine 10 umfasst ein Maschinengehäuse 11, einen Antriebsmotor 12, der in einem Motorturm des Maschinengehäuses 11 untergebracht ist und ein in einer Schneidebene drehbares Schneidmesser 20 antreibt. Das Schneidmesser 20 ist durch eine Messerabdeckung 21 gegen versehentliche Berührung durch den Nutzer geschützt. Zur Einstellung der Scheibendicke ist eine parallel zur Schneidebene einstellbare Anschlagplatte 13 vorhanden. Der Schlitten stützt sich mit einer im Schlittenfuß 14 angebrachten Schlittenbuche 27 auf einer am Maschinengehäuse 11 angebrachten Schlittenachse 17 ab. Die Schlittenbuchse 27 und die Schlittenachse 17 bilden eine Linearführung. Der Schlittenfuß 14 weist einen Rastknopf auf, der durch den Schlittenfuß 14 in eine Arretierung eingreift. Der Schlittenfuß 14 ist durch Lösung des Rastknopfes um die Schlittenachse 17 verkippbar. Auf dem Schlittenfuß 14 ist ein Stützrahmen 15 angebracht. Der Stützrahmen 15 trägt eine Schlittenplatte 16. Auf der Schlittenplatte 16 ist eine Schwenkvorrichtung 30 angebracht, die zur Einstellung des Winkels dient, mit dem das Schneidgut auf die Schneideebene trifft. Dadurch, dass das Schneidgut nicht rechtwinklig, sondern in einem spitzen Winkel (zwischen 16 Grad und 40 Grad) auf die Schneidebene trifft, dringt das Schneidmesser 20 schräg in das Schneidgut ein. Die abgeschnittenen Scheiben haben deswegen einen größeren Querschnitt als wenn das strangförmige Schneidgut im rechten Winkel der Schneidebene zugeführt werden würde. Dies ist insbesondere bei breitem dünnem Schneidgut wie zum Beispiel Fisch und insbesondere Lachs wünschenswert. Die abgeschnittenen Scheiben fallen in einem Ablagebereich (nicht gezeigt) auf ein Förderband 18. Mithilfe eines Interleavers 19 werden Papier- oder Folienblätter zwischen den einzelnen abgeschnittenen Scheiben abgelegt. Ist eine Scheibenportion fertig geschnitten, so wird diese über das Förderband 18 abtransportiert. Fig. 1 shows schematically a cutting machine 10 according to the invention for cutting off slices of particularly wide, thin material to be cut, such as fish, salmon, etc. Fig. 1 a) shows the cutting machine 10 in a side view. Fig. 1 b) shows the cutting machine 10 in an isometric view, with the carriage being slightly spaced apart and shown separately for clearer illustration. The cutting machine 10 comprises a machine housing 11, a drive motor 12, which is accommodated in a motor tower of the machine housing 11 and drives a cutting knife 20 which can be rotated in a cutting plane. The cutting knife 20 is protected against accidental contact by the user by a knife cover 21. To adjust the slice thickness, there is a stop plate 13 that can be adjusted parallel to the cutting plane. The carriage is supported by a carriage beech 27 mounted in the carriage foot 14 on a carriage axle 17 mounted on the machine housing 11. The carriage bushing 27 and the carriage axis 17 form a linear guide. The carriage foot 14 has a locking button which engages in a locking mechanism through the carriage foot 14. The carriage foot 14 can be tilted about the carriage axis 17 by releasing the locking button. A support frame 15 is attached to the carriage base 14. The support frame 15 carries a carriage plate 16. A pivoting device 30 is attached to the carriage plate 16, which serves to adjust the angle at which the material to be cut hits the cutting plane. Because the material to be cut does not hit the cutting plane at a right angle, but rather at an acute angle (between 16 degrees and 40 degrees), the cutting knife 20 penetrates the material to be cut at an angle. The cut slices therefore have a larger cross section than if the strand-shaped material to be cut were fed to the cutting plane at a right angle. This is particularly desirable for wide, thin food such as fish and especially salmon. The cut slices fall onto a conveyor belt 18 in a storage area (not shown). Using an interleaver 19, paper or Sheets of foil are placed between the individual cut slices. Once a slice portion has been cut, it is transported away via the conveyor belt 18.

Die Schwenkvorrichtung 30, mit deren Hilfe das Schneidgut in einem spitzen Winkel, insbesondere im Bereich zwischen 16 Grad und 40 Grad, der Schneidebene zugeführt wird, ist in Fig. 2 a) bis 2 f) gezeigt. Fig. 2 a) zeigt die Schwenkvorrichtung 30 mit darin angebrachtem Rahmen 40, der eine Auflagefläche aus mehreren parallel zueinander angeordneten und um ihre jeweiligen Achsen drehbaren Rollen bildet. Fig. 2b) zeigt die Schwenkvorrichtung 30, wobei der Rahmen 40 abgenommen ist. Fig. 2 c) zeigt die Schwenkvorrichtung 30 in einer Seitenansicht. Die Schwenkvorrichtung 30 ist auf der Schlittenplatte 16 montiert, wobei die Schlittenplatte 16 einen aufrechtstehenden Eingreifschutz 32 umfasst, der in einer Endstellung des Schlittens das Schneidmesser 20 abdeckt und so eine Berührung des Schneidmessers 20 durch den Nutzer verhindert. Die Halterung der Schwenkvorrichtung 30 für den Rahmen 40 ist mittels eines Schwenklagers 33 an einer waagrechten Platte 63 befestigt. Die Schwenkvorrichtung 30 umfasst eine Schneidleiste 31, über die das Schneidgut der Schneidebene zugeführt wird. Die Schneidleiste 31 hat einen Abstand zwischen 0,2 mm und 2 mm, insbesondere 0,5 mm zur Schneidebene. Die Schwenkvorrichtung 30 umfasst zwei Führungsbleche 35, die links und rechts vom Rahmen 40 angebracht sind und eine seitliche Begrenzung der Schwenkvorrichtung 30 bilden. Das Schneidgut liegt an einem der Führungsbleche 35 an, wobei ein seitlicher Gegenhalter 47, der Teil des Rahmens 40 ist, die andere seitliche Begrenzung für das Schneidgut bildet. Die Führungsbleche 35 sind über einen Rahmen 34 der Schneidvorrichtung 30 und mittels mehrere Streben 36 miteinander verbunden. Im Rahmen 34 der Schwenkvorrichtung 30 sind Aufnahmen 67 für eine Schraub-Klemmverbindung angebracht, in denen die Schrauben des Rahmens 40 aufgenommen werden. Mindestens eine Strebe 36 umfasst Aufnahmen 68 für Haken, in denen der Rahmen 40 mit einem Haken eingehängt wird. Außer über das Schwenklager 33 stützt sich die Schwenkvorrichtung 30 über einen Hydraulikzylinder 39 auf der Schlittenplatte 16 ab. Im Hydraulikzylinder 39 ist bewegbar ein Kolben 38 angebracht, der über eine Stützstrebe 37 mit den Führungsblechen 35 verbunden ist. Der Kolben 38 im Hydraulikzylinder 39 ist durch eine Fixierung 60 feststellbar. Der Hydraulikzylinder 39 ist über ein Lager 61 für den Hydraulikzylinder 39 mit der Schlittenplatte 16 verbunden. Unterhalb der Schlittenplatte 16 sind Verschraubungen 66 angebracht, mit der die Schlittenplatte 16 auf der Stützplatte 15 des Schlittens verschraubbar ist. Fig. 2 d) zeigt die Schwenkvorrichtung 30, wenn sie von der Schlittenplatte 16 abgenommen ist. Die waagrechte Platte 63 der Schwenkvorrichtung 30 ist mit einer Fixierungsmutter 64 auf einer Schraube der Schlittenplatte fixierbar. In der waagrechten Platte 63 befinden sich Aufnahmen 69 für Bolzen, welche aus der Schlittenplatte 16 herausragen. Im Hydraulikzylinder 39, an dessen der Stützstrebe 37 abgewandten Seite, befindet sich eine Öffnung 70 für einen Bolzen, der das Lager 61 für den Hydraulikzylinder 39 der Schlittenplatte 16 bildet. Die Fig. 2 e) und 2 f) zeigen die Schlittenplatte 16, wenn der Schwenkvorrichtung 30 abgenommen ist. Die Schlittenplatte 16 umfasst zwei Bolzen 71, die mit den Aufnahmen 69 der waagrechten Platte 63 zusammenwirken. Die Schlittenplatte 16 umfasst des Weiteren eine Schraube 72, die dazu vorgesehen ist, durch eine Bohrung der waagrechte Platte 63 der Schwenkvorrichtung 30 hindurch zu ragen und mittels der Fixierungsmutter 64 die waagrechte Platte 63 gegen die Schlittenplatte 16 zu pressen und somit zu fixieren. Des Weiteren ist auf der Schlittenplatte 16 ein Lager 61 für den Hydraulikzylinder 39 angebracht. Das Lager 61 umfasst eine Entriegelung 62 mit einem Bolzen 73, der in die Öffnung 70 des Hydraulikzylinders 39 eingreift. Durch das Herausziehen der Entriegelung 62 bewegt sich der Bolzen 73 aus der Öffnung 70 des Hydraulikzylinders 39 und der Hydraulikzylinder 39 kann aus dem Lager 61 gelöst werden.The pivoting device 30, with the help of which the material to be cut is fed to the cutting plane at an acute angle, in particular in the range between 16 degrees and 40 degrees, is in Fig. 2 a) to 2 f ) shown. Fig. 2 a) shows the pivoting device 30 with a frame 40 mounted therein, which forms a support surface made up of several rollers arranged parallel to one another and rotatable about their respective axes. Fig. 2b ) shows the pivoting device 30, with the frame 40 removed. Fig. 2 c) shows the pivoting device 30 in a side view. The pivoting device 30 is mounted on the carriage plate 16, the carriage plate 16 comprising an upright engagement guard 32, which covers the cutting knife 20 in an end position of the carriage and thus prevents the user from touching the cutting knife 20. The holder of the pivoting device 30 for the frame 40 is attached to a horizontal plate 63 by means of a pivot bearing 33. The pivoting device 30 includes a cutting bar 31, via which the material to be cut is fed to the cutting plane. The cutting bar 31 has a distance of between 0.2 mm and 2 mm, in particular 0.5 mm, from the cutting plane. The pivoting device 30 includes two guide plates 35, which are attached to the left and right of the frame 40 and form a lateral boundary of the pivoting device 30. The material to be cut lies against one of the guide plates 35, with a lateral counter-holder 47, which is part of the frame 40, forming the other lateral boundary for the material to be cut. The guide plates 35 are connected to one another via a frame 34 of the cutting device 30 and by means of several struts 36. In the frame 34 of the pivoting device 30, receptacles 67 are attached for a screw-clamp connection, in which the screws of the frame 40 are received. At least one strut 36 includes Recordings 68 for hooks, in which the frame 40 is hung with a hook. In addition to the pivot bearing 33, the pivoting device 30 is supported on the slide plate 16 via a hydraulic cylinder 39. A piston 38 is movably mounted in the hydraulic cylinder 39 and is connected to the guide plates 35 via a support strut 37. The piston 38 in the hydraulic cylinder 39 can be locked by a fixation 60. The hydraulic cylinder 39 is connected to the carriage plate 16 via a bearing 61 for the hydraulic cylinder 39. Below the slide plate 16 there are screw connections 66 attached, with which the slide plate 16 can be screwed onto the support plate 15 of the slide. Fig. 2d) shows the pivoting device 30 when it is removed from the carriage plate 16. The horizontal plate 63 of the pivoting device 30 can be fixed with a fixing nut 64 on a screw of the carriage plate. In the horizontal plate 63 there are receptacles 69 for bolts, which protrude from the carriage plate 16. In the hydraulic cylinder 39, on the side facing away from the support strut 37, there is an opening 70 for a bolt, which forms the bearing 61 for the hydraulic cylinder 39 of the carriage plate 16. The Fig. 2 e) and 2 f ) show the carriage plate 16 when the pivoting device 30 is removed. The carriage plate 16 includes two bolts 71 which cooperate with the receptacles 69 of the horizontal plate 63. The carriage plate 16 further comprises a screw 72, which is intended to protrude through a hole in the horizontal plate 63 of the pivoting device 30 and to press the horizontal plate 63 against the carriage plate 16 by means of the fixing nut 64 and thus fix it. Furthermore, a bearing 61 for the hydraulic cylinder 39 is mounted on the carriage plate 16. The bearing 61 includes an unlocking mechanism 62 with a bolt 73 which engages in the opening 70 of the hydraulic cylinder 39. By pulling out the unlocking 62, the bolt 73 moves out of the opening 70 of the hydraulic cylinder 39 and the hydraulic cylinder 39 can be released from the bearing 61.

Fig. 3 a) bis 3 c) zeigen den Rahmen 40 in einer ersten Ansicht, in einer isometrischen Ansicht und in einem Schnitt. Der Rahmen 40 ist aus der Schwenkvorrichtung 30 werkzeuglos entnehmbar. Der Rahmen 40 ist aufgebaut aus einem oberen Rahmen 46, an dem zwei seitliche Rahmen 42 angebracht sind. Die seitlichen Rahmen 42 sind durch Streben 43 zur Stabilisierung miteinander verbunden. In den seitlichen Rahmen 42 befinden sich Bohrungen, in denen die Rollen 41, die die Auflagefläche bilden, drehbar angebracht sind. An mindestens einer Strebe 43 ist ein seitlicher Gegenhalter 47 angebracht, der in Richtung der Achsen der Rollen 41 zwischen den beiden seitlichen Rahmen 42 bewegbar ist. Der seitliche Gegenhalter 47 dient als seitliche Begrenzung für das Schneidgut. Der seitliche Gegenhalter 47 ist an mindestens einer Strebe 43 mittels einer Schraubfixierung 48 festklemmbar. Die Rollen 41 sind in einem von der Schneidebene entfernten Bereich des Rahmens 40, mit einem zweiten Abstand d2 beanstandet. In einem näher an der Schneidebene befindlichen Bereich sind die Rollen 41 mit einem ersten Abstand d1 beabstandet. Der zweite Abstand d2 ist größer als der erste Abstand d1. Das heißt, in der Nähe der Schneidebene sind die Rollen 41 dichter angeordnet, sodass das Schneidgut besser abgestützt wird. Da die Rollen das Schneidgut aufgrund ihrer Ringe (in Fig. 4 gezeigt) seitlich stützen, verleiht die höhere Dichte an Rollen 41 dem Schneidgut eine seitliche Stabilität. Das heißt, wird durch den Schneidvorgang durch das Schneidmesser 20 auf das Schneidgut eine Kraft entlang der Achse der Rollen 41 ausgeübt, so wirken die Ringe auf den Rollen 41, die das Schneidgut stützen, dieser Kraft entgegen. Durch die höhere Anzahl von Rollen 41 im Bereich der Schneideebene kann so eine bessere Fixierung des Schneidgutes garantiert werden. Gleichzeitig ist durch die Ausgestaltung der Auflagefläche als Rollen 41 die Beweglichkeit des Schneidgutes hin zur Schneidebene gegeben. So ist das Schneidgut in Richtung parallel zur Schneidebene fixiert, jedoch in Richtung hin zur Schneidebene gut bewegbar. Daraus ergibt sich ein optimales Schneidergebnis. An dem seitlichen Rahmen 42 sind Haken 44 befestigt, die zum Einhängen des Rahmens 40 in die Aufnahmen 68 der Streben 36 der Schwenkvorrichtung 30 dienen. Am oberen Rahmen 46 sind zwei Schraub-Klemmverbindungen 45 angebracht. Die Schrauben der Schraub-Klemmverbindungen 45 werden beim Anbringen des Rahmens 40 in der Schwenkvorrichtung 30 in die Aufnahmen 67 des Rahmens 34 der Schwenkvorrichtung 30 eingeführt und mittels der Schrauben verklemmt. Durch die Schrauben der Schraub-Klemmverbindung 45 ist der Abstand 51 zwischen dem oberen Rahmen 46 und der Mutter der Schraub-Klemmverbindung 45 einstellbar. An dem seitlichen Gegenhalter 47 ist ein waagrechter Gegenhalter 49 angebracht, der einen Abstand zur Auflagefläche, die durch die Rollen 41 gebildet wird, hat. Der waagrechte Gegenhalter 49 verhindert ein Abkippen des Schneidgutes von den Rollen 41. Der Abstand des waagrechten Gegenhalters 49 ist einstellbar und der waagrechte Gegenhalter 49 ist mit einer Fixierung 50 fixierbar. Der waagrechte Gegenhalter 49 ist über ein Langloch 52 in seinem Abstand zur, durch die Rollen 41 gebildeten, Auflagefläche einstellbar und mit der Fixierung 50 fixierbar. Der waagrechte Gegenhalter 49 dient zum Verhindern eines Abkippens des Schneidgutes. Er ist nicht dazu ausgelegt, das Schneidgut direkt zu berühren, sondern mit dem Langloch 52 wird ein gewisser kleiner Abstand zwischen Schneidgut und waagrechtem Gegenhalter 49 eingestellt. So ist sichergestellt, dass auch Schneidgut mit leicht variabler Dicke sich unter dem waagrechten Gegenhalter 49 durchbewegt. Sollte es zu einem Lösen des Schneidgutes von der Auflagefläche kommen, so wird es durch den waagrechten Gegenhalter 49 am Abkippen gehindert und fällt durch die Schwerkraft zurück auf die Auflagefläche, die durch die Rollen 41 gebildet ist. Fig. 3 a) to 3 c ) show the frame 40 in a first view, in an isometric view and in a section. The frame 40 can be removed from the pivoting device 30 without tools. The frame 40 is constructed from an upper frame 46 to which two side frames 42 are attached. The side frames 42 are connected to one another by struts 43 for stabilization. There are holes in the side frame 42 in which the rollers 41, which form the support surface, are rotatably mounted. A lateral counter-holder 47 is attached to at least one strut 43 and can be moved in the direction of the axes of the rollers 41 between the two lateral frames 42. The lateral counter-holder 47 serves as a lateral boundary for the material to be cut. The lateral counter-holder 47 can be clamped to at least one strut 43 by means of a screw fixation 48. The rollers 41 are spaced at a second distance d2 in an area of the frame 40 remote from the cutting plane. In an area closer to the cutting plane, the rollers 41 are spaced apart by a first distance d1. The second distance d2 is greater than the first distance d1. This means that the rollers 41 are arranged closer together near the cutting plane, so that the material to be cut is better supported. Since the rollers hold the food to be cut due to their rings (in Fig. 4 shown) support laterally, the higher density of rollers 41 gives the material to be cut lateral stability. This means that if a force is exerted on the material to be cut along the axis of the rollers 41 as a result of the cutting process by the cutting knife 20, the rings on the rollers 41, which support the material to be cut, counteract this force. Due to the higher number of rollers 41 in the area of the cutting plane, better fixation of the material to be cut can be guaranteed. At the same time, the design of the support surface as rollers 41 ensures that the material to be cut can move towards the cutting plane. In this way, the material to be cut is fixed in a direction parallel to the cutting plane, but in a direction towards it Cutting plane can be easily moved. This results in an optimal cutting result. Hooks 44 are attached to the side frame 42 and are used to hang the frame 40 in the receptacles 68 of the struts 36 of the pivoting device 30. Two screw-clamp connections 45 are attached to the upper frame 46. When attaching the frame 40 in the pivoting device 30, the screws of the screw-clamp connections 45 are inserted into the receptacles 67 of the frame 34 of the pivoting device 30 and clamped by means of the screws. The distance 51 between the upper frame 46 and the nut of the screw-clamp connection 45 can be adjusted by means of the screws of the screw-clamp connection 45. A horizontal counter-holder 49 is attached to the side counter-holder 47 and is at a distance from the support surface formed by the rollers 41. The horizontal counter-holder 49 prevents the material to be cut from tipping off the rollers 41. The distance of the horizontal counter-holder 49 is adjustable and the horizontal counter-holder 49 can be fixed with a fixation 50. The horizontal counter-holder 49 can be adjusted in its distance from the support surface formed by the rollers 41 via an elongated hole 52 and can be fixed with the fixation 50. The horizontal counter-holder 49 serves to prevent the material to be cut from tipping over. It is not designed to touch the material to be cut directly, but rather a certain small distance between the material to be cut and the horizontal counter-holder 49 is set with the elongated hole 52. This ensures that even items to be cut with a slightly variable thickness move through under the horizontal counter-holder 49. If the material to be cut comes loose from the support surface, it is prevented from tipping over by the horizontal counter-holder 49 and falls back onto the support surface, which is formed by the rollers 41, due to gravity.

Fig. 4 zeigt eine Rolle 41, wie sie in dem Rahmen 40 der Schwenkeinrichtung 30 verbaut ist und die Auflagefläche für das Schneidgut bildet. Die Rolle 41 umfasst entlang ihrer Achse in regelmäßigen Abständen 81 Ringe 82, die im Vergleich zum Durchmesser des Teils der Rolle 41 zwischen den Ringen 82 dicker sind und deshalb etwas erhöht sind. Die Ringe 82 haben einen 4 mm größeren Durchmesser als die Teile der Rolle 41 zwischen den Ringen 82. Teil Fig. 4 zeigt einen vergrößerten Ausschnitt 85 eines dieser Ringe 82. Die Ringe weisen entlang ihres Radius eine Schräge 83 auf und werden mit einer Spitze 84 abgeschlossen. Die Spitze 84 ist derart gestaltet, dass sie leicht in das Schneidgut eindringt, das Schneidgut jedoch nicht schneidet. Die Spitze 84 ist als kleiner Radius mit vorzugsweise 0,2 mm ausgebildet. Da die Spitze 84 direkten Lebensmittelkontakt hat, ist es wichtig, dass sich bei der Herstellung an der Spitze 84 kein Grat bildet. Aus diesem Grund ist die Spitze 84 leicht abgerundet. Vorzugsweise handelt sich es sich bei der Rolle 41 um ein Drehteil, das einstückig ausgebildet ist. Das verhindert wirkungsvoll das Bilden von Bakteriennestern, da keine Spalte entstehen, wie es bei einer mehrteiligen Rolle der Fall wäre. Die mit einem geringeren Radius ausgebildeten Enden 80 der Rolle 41 sind drehbar in dafür vorgesehenen Bohrungen der seitlichen Rahmen 42 der Rahmens 40 der Schwenkvorrichtung 30 angebracht. Fig. 4 shows a roller 41 as it is installed in the frame 40 of the pivoting device 30 and forms the support surface for the material to be cut. The roller 41 includes along it Axis at regular intervals 81 rings 82, which are thicker compared to the diameter of the part of the roller 41 between the rings 82 and are therefore slightly raised. The rings 82 have a 4 mm larger diameter than the parts of the roller 41 between the rings 82. Part Fig. 4 shows an enlarged section 85 of one of these rings 82. The rings have a slope 83 along their radius and are terminated with a tip 84. The tip 84 is designed in such a way that it easily penetrates the material to be cut, but does not cut the material to be cut. The tip 84 is designed as a small radius, preferably 0.2 mm. Since the tip 84 is in direct contact with food, it is important that no burrs form on the tip 84 during manufacture. For this reason, the tip 84 is slightly rounded. The roller 41 is preferably a rotating part that is formed in one piece. This effectively prevents the formation of bacterial nests as there are no gaps, as would be the case with a multi-part roll. The ends 80 of the roller 41, which are designed with a smaller radius, are rotatably mounted in holes provided in the side frames 42 of the frame 40 of the pivoting device 30.
