Description

Die Erfindung betrifft eine Maschine zum Schneiden von Lebensmitteln, insbesondere von Gemüse, in Streifen mit einer in einem Maschinengestell rotierbaren Trommel, deren Mantel mindestens einen Durchbruch aufweist, durch den im Inneren der Trommel befindliches und mit dieser rotierbares Schneidgut infolge der Zentrifugalkraft radial nach außen austritt, wobei von dem Schneidgut mittels eines mit dem Maschinengestell verbundenen Messers Scheiben abschneidbar sind, die mittels eines Kreismessersatzes, der eine Mehrzahl von auf einer gemeinsamen Welle drehantreibbar angeordneten, scheibenförmigen Kreismessern aufweist, in Streifen schneidbar sind.The invention relates to a machine for cutting food, in particular of vegetables, in strips with a drum rotatable in a machine frame, whose shell has at least one opening through which inside the Drum located and rotatable with this cutting material due to the centrifugal force emerges radially outward, wherein of the material to be cut by means of a with the Machine frame connected knife discs are cut off by means of a circular meter set, a plurality of rotatably drivable on a common shaft arranged, disc-shaped circular knives, in strips are cut.

Derartige Maschinen sind beispielsweise aus der US-A-2,541,180 bekannt und werden insbesondere zum Schneiden von Kartoffeln, Möhren, Sellerie, Rettichen, Zwiebeln und anderem Gemüse, aber auch zum Schneiden von gefrorenem Fleisch, eingesetzt. Die Trommel wirkt als Zentrifuge, an deren Mantel innenseitig eine Mehrzahl von in axialer Richtung verlaufenden Mitnehmerrippen angeordnet sind, die dafür sorgen, daß das in der Trommel befindliche Schneidgut der Rotation der Trommel schlupffrei folgt. Des weiteren kommt den Mitnehmerrippen die Aufgabe zu, die beim Abschneiden der Scheiben erforderliche Gegenkraft auf das Schneidgut auszuüben.Such machines are known for example from US-A-2,541,180 and are used in particular for cutting potatoes, carrots, celery, radishes, onions and other vegetables, but also for cutting frozen meat, used. The drum acts as Centrifuge, on whose jacket inside a plurality of extending in the axial direction Mitnehmerrippen are arranged, which ensure that in the drum located cutting material of the rotation of the drum follows without slip. Furthermore The driving ribs take on the task of cutting the discs to exert the necessary counterforce on the material to be cut.

Die Schneidgutzufuhr erfolgt in der Regel über einen Trichter, von dem das Schneidgut zu einer zentralen Öffnung in einer Stirnseite der Trommel geleitet wird. Die gegenüberliegende Stirnseite der Trommel, deren Drehachse in der Regel horizontal verläuft, ist geschlossen ausgebildet, so daß das Schneidgut bei rotierender Trommel lediglich durch die Durchbrüche in dem Trommelmantel austreten kann.The crop feed is usually via a hopper, of which the cut material is directed to a central opening in an end face of the drum. The opposite Front side of the drum, whose axis of rotation is usually horizontal runs, is closed, so that the material to be cut with rotating drum can only escape through the openings in the drum shell.

Um anstelle von Streifen des Schneidgutes Würfel zu erhalten, besitzen die Maschinen nach dem Stand der Technik häufig eine dem Kreismessersatz nachgeschaltete weitere Schneideinrichtung, die in Form einer sogenannten Hackwalze ausgeführt ist. Mit dieser Hackwalze, die mit mehreren über ihren Umfang verteilt angeordneten balkenförmigen Messern versehen und mit ihrer Drehachse parallel zu dem Kreismessersatz ausgerichtet ist, werden die aus dem Kreismessersatz austretenden und über eine Gegenschneide geführten Streifen in Würfel bzw. Quader zerteilt.In order to obtain cubes instead of strips of the cutting material, the machines own in the prior art often followed by the circular meter set further cutting device, which is designed in the form of a so-called chopping roller. With this Hackwalze, which arranged with several distributed over its circumference provided with bar-shaped knives and with its axis of rotation parallel to the circular knife set aligned, are emerging from the circular knife set and divided into cubes or cubes by means of a counter-cut strip.

Ein Nachteil der bekannten Maschinen besteht darin, daß insbesondere empfindliche Schneidgüter beim Durchtritt durch den Kreismessersatz einer großen Druckbelastung ausgesetzt sind. Diese rührt daher, daß die in die abgeschnittenen Scheiben eindringenden Kreismesser unvermeidlich eine Schneidgutverdrängung bewirken, die eine Kompression des Schneidguts nach sich zieht. Insbesondere bei druckempfindlichen und saftreichen Schneidgütern, wie beispielsweise Zwiebeln, kommt es daher zu einer unerwünscht großen Entsaftung, die als eindeutiger Qualitätsmangel der geschnittenen Streifen bzw. Würfel anzusehen ist. Bestrebungen, die Druckbelastung durch eine verminderte Dicke der Kreismesser zu reduzieren, sind durch eine nicht zu unterschreitende Mindestmaterialstärke sehr enge Grenzen gesetzt.A disadvantage of the known machines is that particularly sensitive Products to be cut when passing through the circular knife set of a large pressure load are exposed. This is due to the fact that in the cut slices invading circular blades inevitably cause a Schneidgutverdrängung which entails a compression of the material to be cut. Especially with pressure sensitive and juicy cuttings such as onions therefore to an undesirably large juicing, as a clear lack of quality the cut strip or cube is to be regarded. Aspirations, the pressure load By reducing the thickness of the circular blades are reduced by a not to be fallen below minimum material strength set very narrow limits.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidmaschine vorzuschlagen, mit der auch empfindliche und saftreiche Schneidgüter ohne Qualitätsminderung in Streifen oder Würfel schneidbar sind.The invention has for its object to provide a cutting machine, with the sensitive and juicy cuttings without quality reduction in stripes or cubes are cuttable.

Ausgehend von einer Maschine der eingangs beschriebenen Art, wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß in Förderrichtung der abgeschnittenen Scheiben mindestens zwei Kreismessersätze hintereinander angeordnet sind, deren Wellen parallel zueinander verlaufen, wobei die Kreismesser des zweiten Kreismessersatzes senkrecht zur Förderrichtung zu den Kreismessern des ersten Kreismessersatzes versetzt angeordnet sind.Starting from a machine of the type described above, this task According to the invention solved in that in the conveying direction of the cut slices at least two circular knife sets are arranged one behind the other, whose waves parallel to each other, wherein the circular blade of the second circular meter set perpendicular to the conveying direction to the circular knives of the first circular knife set are arranged offset.

Bei der erfindungsgemäßen Maschine wird die Druckbelastung des Schneidguts beispielsweise bei der Verwendung von zwei hintereinander angeordneten Kreismessersätzen halbiert, da in jeder der beiden hintereinandergeschalteten Stufen nur die Hälfte der insgesamt auf beiden Messersätzen vorhandenen Kreismesser mit dem Produkt im Eingriff sind. Auf diese Weise kann der Saftverlust bei in dieser Hinsicht empfindlichen Schneidgütem deutlich reduziert werden. In the machine according to the invention, the pressure load of the material to be cut, for example when using two circular knife sets arranged one behind the other halved, since in each of the two stages connected in series, only the Half of the total on both knife sets existing circular knife with the Product are engaged. In this way, the juice loss can help in this regard sensitive Schneidgütem be significantly reduced.

Auch wenn die Verminderung der Schneidgutbelastung durch die Hintereinanderschaltung von mehr als zwei Kreismessersätzen weiter gesenkt werden kann, wird dies aufgrund des steigenden Bauaufwandes sowie des wachsenden Raumbedarfs für die Maschine nur in Ausnahmefällen, d.h. bei sehr empfindlichen Schneidgütem bzw. sehr hohen Anforderungen an die Produktqualität bzw. Safthaltung, gerechtfertigt sein. Die Verwendung von zwei Kreismessersätzen dürfte im Normalfall den besten Kompromiß zwischen hinreichender Minimierung der Schneidgutbelastung sowie Vermeidung eines unnötig großen Herstellungsaufwandes darstellen.Even if the reduction of Schneidgutbelastung by the series connection of more than two circular knife sets can be further lowered this due to the increasing construction costs and the growing space requirements for the machine only in exceptional cases, i. for very sensitive cuttings or very high demands on the product quality or juice maintenance, justified be. The use of two circular knife sets is usually the best A compromise between adequate minimization of the crop load as well Avoidance of unnecessarily large production costs.

Insofern ist es besonders vorteilhaft, wenn zwei Kreismessersätze vorhanden sind, deren Kreismesser in axialer Richtung äquidistant zueinander mit jeweils identischer Teilung angeordnet sind, wobei der Versatz zwischen den Kreismessern der halben Teilung entspricht, um auf diese Weise nach Austritt des Schneidguts aus dem zweiten Kreismessersatz sämtlich identisch breite Schneidgutstreifen zu erhalten.In this respect, it is particularly advantageous if two circular knife sets are present, their circular knives in the axial direction equidistant to each other, each with identical Division, wherein the offset between the circular knives of half Division corresponds to in this way after the emergence of the crop from the second Circle knife set to receive all identical wide slices of cutting material.

Gemäß einer Ausgestaltung der erfindungsgemäßen Maschine wird vorgeschlagen, daß die Kreismesser des ersten Kreismessersatzes sich in die Zwischenräume zwischen den Kreismessern des zweiten Kreismessersatzes erstrecken, wobei der Abstand der Drehachsen ungefähr so bemessen ist, daß die in eine Ebene parallel zu den Kreismessern projizierten Umrißlinien der Kreismesser der beiden Kreismessersätze sich in einer Tangentialebene an die äußeren Mantelflächen der beiden Wellen der Kreismessersätze schneiden.According to one embodiment of the machine according to the invention, it is proposed that the circular knives of the first circular knife set themselves in the spaces between extend the circular knives of the second circular knife set, wherein the distance the axes of rotation is approximately dimensioned so that in a plane parallel to The circle knives projected outlines of the circular knives of the two circular knife sets in a tangential plane to the outer surfaces of the two waves cutting the circle knife sets.

Mit einer derartigen Ausgestaltung wird erreicht, daß über keine größere Strecke in Förderrichtung die Kreismesser beider Kreismessersätze gleichzeitig im Eingriff sind. Vielmehr beginnt der Eingriffsbereich des zweiten Kreismessersatzes im wesentlichen erst dort, wo die Kreismesser des ersten Kreismessersatzes das Schneidgut bereits wieder verlassen haben. With such a configuration it is achieved that no greater distance in Direction of conveying the circular blades of both circular blade sets are simultaneously engaged. Rather, the engagement area of the second circular meter set essentially begins only there, where the circular knives of the first circular knife set the cutting material have already left again.

Während eine Reduzierung des Abstandes der Drehachsen der beiden Kreismesser deutlich unter den vorstehend definierten Abstand zu einer unerwünschten Erhöhung der Druckbelastung führt, ist eine Vergrößerung des Abstands über das vorgenannte Maß hinaus nicht vorteilhaft, da hierdurch zum einen der Bauraum der Maschine unnötig anwachsen würde und zum anderen die Führung der von dem ersten Kreismessersatz bereits geschnittenen Streifen zwischen den beiden Kreismessersätzen erschwert würde. Bei dem wie vorstehend beschrieben gewählten Drehachsenabstand ist stets eine sichere seitliche Führung des Schneidguts gegeben, da die Eingriffsbereiche der beiden Kreismessersätze unmittelbar aneinander angrenzen.While reducing the distance between the axes of rotation of the two circular knives significantly below the above-defined distance to an undesired increase the pressure load is an increase in the distance above the aforementioned Dimension beyond not advantageous, as a result, on the one hand, the space of the machine unnecessary and on the other hand the leadership of the first circular knife set already cut strips between the two circular knife sets would be difficult. In the rotary axis distance selected as described above is always a safe lateral guidance of the material to be cut given because the engagement areas the two circular knife sets directly adjacent to each other.

Eine Weiterbildung der Erfindung besteht schließlich noch darin, daß im Bereich der Kreismessersätze ein Schlitzblech vorgesehen ist, das den Förderquerschnitt zu den Drehachsen der Kreismessersätze hin begrenzt und von den Kreismessern der Kreismessersätze in Schlitzen, die in ihrer Länge und Breite an die Kreismesser angepaßt sind, durchdrungen wird. Auf diese Weise kann ein unerwünschtes Eindringen von Schneidgut in Bereiche zwischen die Wellen der Kreismessersätze verhindert und somit eine durchgängige Produktführung erzielt werden.A development of the invention finally consists in that in the field of Kreismessersätze a slotted plate is provided, which the conveyor cross section to the Rotary axes of the Kreismessersätze limited and of the circular knives of Circular knife sets in slots adapted in their length and width to the circular blade are, are penetrated. In this way, an unwanted intrusion of cutting material in areas between the waves of the Kreismessersätze prevented and thus a continuous product management can be achieved.

Eine besonders einfache Verstellung der Höhe des Förderquerschnitts - in Abhängigkeit von der eingestellten Dicke der abgeschnittenen Scheiben - läßt sich dann verwirklichen, wenn das Schlitzblech einstückig ausgebildet ist.A particularly simple adjustment of the height of the conveyor section - in dependence from the set thickness of the cut slices - can then be realize when the slot plate is formed integrally.

Die in Fig. 1 dargestellte Maschine 1 zum Schneiden insbesondere von Gemüse in Würfel weist eine Trommel 2 mit horizontaler Drehachse auf, die über einen Trichter 3, der in eine nicht dargestellte Öffnung innerhalb einer Stirnseite der Trommel 2 mündet, mit Schneidgut bestückbar ist. Das infolge der Zentrifugalkraft radial durch Durchbrüche in der Trommel 2 hervortretende Schneidgut wird mit Hilfe eines fest mit einem Maschinengestell verbundenen Messers in Scheiben geschnitten. Diese Scheiben werden anschließend mit Hilfe zweier Kreismessersätze 4 und 5, deren Drehachsen parallel zur Drehachse der Trommel 2 verlaufen, in Streifen geschnitten. Anschließend werden diese Streifen mit Hilfe einer aufgrund einer Abdeckung 6 nicht sichtbaren Hackwalze in Würfel zerteilt. Die Schneidgutwürfel verlassen die Maschine 1 durch den Austrittsquerschnitt eines von der Abdeckung 6 gebildeten Auswurfschachts.The machine 1 shown in Fig. 1 for cutting in particular vegetables in Cube has a drum 2 with horizontal axis of rotation, which via a funnel 3, in an unillustrated opening within an end face of the drum. 2 opens, can be equipped with items to be cut. The radially due to the centrifugal force Breakthroughs in the drum 2 protruding material to be cut with the help of a firm sliced with a machine frame connected knife. These Slices are then using two Kreismessersätze 4 and 5, whose Rotary axes parallel to the axis of rotation of the drum 2, cut into strips. Subsequently, these strips with the help of a due to a cover 6 not visible hack roll cut into cubes. The cuttings leave the machine 1 through the outlet cross section of an ejection shaft formed by the cover 6.

Wie sich aus der Schnittdarstellung in Fig. 2 ergibt, ist die Trommel 2 mit vier Mitnehmerrippen 7 versehen, die bewirken, daß das axial eingeführte Schneidgut sich in den Randbereichen des Trommelquerschnitts in etwa synchron mit der Trommel 2 bewegt. In einem Bereich seitlich neben der Trommel 2 befinden sich schräg untereinander die beiden Kreismessersätze 4 und 5. Die im Entstehen begriffenen Scheiben, die - ausgehend von der Schneidkante 8 des feststehenden Messers 9 - die Trommel 2 in tangentialer Richtung verlassen, werden hintereinander von den Kreismessersätzen 4 und 5, deren Außenkonturen in Fig. 2 nicht maßstäblich wiedergegeben sind, in Streifen zerschnitten. Im Anschluß an die Kreismessersätze 4 und 5 befindet sich eine Hackwalze 10 mit fünf in Umfangsrichtung verteilt und parallel zueinander angeordneten Messerbalken 11, die mit der hinteren Kante 12 des Messers 9 in Form einer Gegenschneide zusammenarbeiten. In Abhängigkeit von der Drehzahl der Hackwalze 10 werden die aus dem zweiten Kreismessersatz 5 austretenden Streifen in Würfel bzw. Quader zerteilt. As is apparent from the sectional view in Fig. 2, the drum 2 with four driving ribs 7, which cause the axially introduced cutting material in the edge regions of the drum cross section in approximately synchronous with the drum second emotional. In an area laterally adjacent to the drum 2 are at an angle to each other the two circular knife sets 4 and 5. The emerging discs, which - starting from the cutting edge 8 of the fixed blade 9 - the Drum 2 leave in the tangential direction, are consecutively from the Circular knife sets 4 and 5, the outer contours in Fig. 2 are not reproduced to scale are cut into strips. Following the circular knife sets 4 and 5 is a hacking roll 10 with five circumferentially distributed and parallel arranged to each other cutter bar 11, with the rear edge 12 of the Knife 9 cooperate in the form of a counter-blade. In dependence of the speed of the chopping roll 10 are the emerging from the second circular knife set 5 Strip into cubes or cubes parts.

Wie sich der Fig. 3 entnehmen läßt, ist ein die Trommel 2 umgebender Zylinder 13 in einem Austrittsbereich 14, der in Drehrichtung (Pfeil 15) der Trommel 2 dem feststehenden Messer 9 vorgelagert ist, spiralförmig erweitert. Auf diese Weise erfolgt nach einem gesteuerten Durchtritt des Schneidguts durch den jeweiligen Durchbruch in der Trommel 2 das Abschneiden einer Scheibe der Dicke 16. Infolge der Zentrifugalkraft liegt das Schneidgut im Austrittsbereich stets an der Innenwand 17 des Zylinders 13 an, die sich zunehmend von der Drehachse der Trommel 2 entfernt. Mit Hilfe einer Verstelleinrichtung 18 läßt sich die Dicke 16 der Scheiben variieren.As can be seen from FIG. 3, a cylinder 13 surrounding the drum 2 is shown in FIG an exit region 14, in the direction of rotation (arrow 15) of the drum 2 the fixed Knife 9 is upstream, spirally widened. This is done after a controlled passage of the material to be cut through the respective breakthrough in the drum 2 cutting a disk of thickness 16. Due to the centrifugal force the material to be cut always lies in the outlet area on the inner wall 17 of the cylinder 13, which increasingly moves away from the axis of rotation of the drum 2. With help an adjustment 18, the thickness 16 of the discs can be varied.

Die abgeschnittenen Scheiben durchlaufen anschließend zwei Kreismessersätze 4 und 5, deren Drehachsen parallel zueinander und zu der Drehachse der Trommel 2 ausgerichtet sind. Jeder Kreismessersatz 4, 5 weist eine Mehrzahl von parallel zueinander angeordneten, scheibenförmigen Kreismessern 19 und 20 auf.The cut slices then pass through two circular knife sets 4 and 5, the axes of rotation parallel to each other and to the axis of rotation of the drum. 2 are aligned. Each circular knife set 4, 5 has a plurality of parallel to each other arranged, disc-shaped circular knives 19 and 20.

Diese Kreismesser 19 und 20 dringen zu einem geringen Betrag ihres Durchmessers in angepaßte rinnenförmige Mulden 21 in dem Messer 9 ein, weshalb ein sicheres Zertrennen der Scheiben zu Streifen gewährleistet wird.These circular knives 19 and 20 penetrate to a small amount of their diameter in matched channel-shaped wells 21 in the knife 9, which is why a secure Dividing the slices into strips is ensured.

Der Förderquerschnitt der Streifen wird in Richtung auf die Drehachsen der Kreismessersätze 4 und 5 von einem Schlitzblech 22 begrenzt, in dessen Schlitze die Kreismesser 19 und 20 eindringen. Das Schlitzblech 22 verhindert, daß die geschnittenen Streifen infolge einer Reibung an den Flanken der Kreismesser 19 und 20 von dem Messer 19 abgehoben und auf einer kreisförmigen Bahn in Bereiche zwischen den Wellen der Kreismessersätze 4, 5 bzw. hinter der Welle des zweiten Kreismessersatzes 5 bewegt werden.The conveyor cross section of the strips is directed towards the axes of rotation of the circular knife sets 4 and 5 bounded by a slot plate 22, in the slots of the Circle knives 19 and 20 penetrate. The slotted plate 22 prevents the cut Strip due to friction on the flanks of the circular blades 19 and 20 of the knife 19 lifted and on a circular path in areas between the waves of the Kreismessersätze 4, 5 and behind the shaft of the second Circular meter set 5 moves.

Wie in Fig. 3, aber auch in Fig. 4 dargestellt ist, erstrecken sich die Kreismesser 19 des ersten Kreismessersatzes 4 in die Zwischenräume zwischen den Kreismessern 20 des zweiten Kreismessersatzes 5 bzw. umgekehrt. Durch diese Überlappung der Kreismesser 19 und 20 in einer die Drehachsen der Kreismessersätze 4 und 5 verbindenden Ebene wird erreicht, daß das Schneidgut nach einem Austritt aus dem Kreismessersatz 4 unmittelbar in den Kreismessersatz 5 eintritt. Da der Förderquerschnitt in bezug auf die vorgenannte Verbindungsebene zwischen den Drehachsen der Kreismessersätze 4 und 5 versetzt angeordnet ist, ist innerhalb des Förderquer schnitts mit Ausnahme des Bereichs des Zwickels 23 keine Überlappung der Kreismesser 19 und 20 vorhanden, so daß sich im wesentlichen entweder nur die Kreismesser 19 des ersten Kreismessersatzes 4 oder die Kreismesser 20 des zweiten Kreismessersatzes 5 im Eingriff mit den zu zerteilenden Scheiben befinden. Die Druckbelastung des Schneidguts wird aufgrund der Verdrängung entweder lediglich durch die Kreismesser 19 oder lediglich durch die Kreismesser 20 im Vergleich zu Maschinen mit einem einzigen Kreismessersatz, der die doppelte Anzahl von Kreismessern aufweist, dadurch ungefähr halbiert.As shown in Fig. 3, but also in Fig. 4, the circular blades 19 extend of the first circular knife set 4 in the spaces between the circular knives 20 of the second circular meter set 5 or vice versa. Due to this overlap of Circular knives 19 and 20 in one of the axes of rotation of the Kreismessersätze 4 and 5 connecting Level is achieved that the cut material after leaving the Circular knife set 4 enters directly into the circular knife set 5. As the conveyor cross section with respect to the aforementioned connection plane between the axes of rotation the Kreismessersätze 4 and 5 is arranged offset, is within the Förderquer cut except for the area of the gusset 23 no overlap of the circular blade 19 and 20 present, so that essentially either only the circular blade 19 of the first circular knife set 4 or the circular knives 20 of the second Circular meter set 5 are in engagement with the discs to be divided. The Pressure load of the crop is due to the displacement either only by the circular knives 19 or only by the circular knives 20 in comparison to Machines with a single circular knife set, which is twice the number of circular knives thereby approximately halved.

Die Streifen werden nach Verlassen des zweiten Kreismessersatzes 5 mit Hilfe einer um eine parallele Drehachse rotierenden Hackwalze 24 in Würfel zerteilt. Die Hackwalze 24 weist fünf über den Umfang eines im Querschnitt sternförmigen Walzenkörpers 25 verteilt angeordnete Balkenmesser 26 auf, die in dichtem Abstand die hintere Kante 27 des Schlitzblechs 22 passieren und mit ihrer Vorderkante 28 nach Durchlaufen des Förderquerschnitts mit der hinteren Kante 29 des Messers 9 in Form einer Gegenschneide zusammenwirken. Eine Druckbelastung des Schneidguts findet durch die Hackwalze nicht statt, da aufgrund der großen freien Länge der Messerbalken 26 in Verbindung mit der Höhe der Rippen 30 des Walzenkörpers 25 genügend Raum zum Abfallen der Würfel besteht.The strips are after leaving the second circular set of 5 using a about a parallel axis of rotation rotating Hackwalze 24 into cubes. The Hackwalze 24 has five over the circumference of a cross-sectionally star-shaped roller body Distributed 25 arranged balancing knife 26, which at a close distance the trailing edge 27 of the slot plate 22 pass and with its leading edge 28 after Passing through the conveyor cross section with the rear edge 29 of the knife 9 in Form a counter-knife interact. A compressive load of the material to be cut does not take place by the Hackwalze, because of the large free length of Blade 26 in conjunction with the height of the ribs 30 of the roller body 25th there is enough room to drop the dice.
