Abstract

A food e.g. cheese or sausage slicing machine has a rotating cutting blade (2) that slides between slices along a plane parallel to its axis of rotation (3). The movement between slices is effected by a regulated drive system (6, 8, 9). The assembly includes a mass balance (4) that moves in the opposite direction to the blade under the guidance of the regulated drive system. The lateral movement of the blade and mass balance is independent of the blade speed of rotation.

Description

Die vorliegende Erfindung betrifft eine Aufschneidevorrichtung zum Aufschneiden von Lebensmitteln, insbesondere von Wurst-, Fleisch- oder Käseriegeln mit einem rotierenden Schneidmesser, das parallel zu seiner Rotationsachse verschieblich gelagert ist.The present invention relates to a slicing device for slicing food, in particular sausage, meat or cheese bars with a rotating cutting blade, which is slidably mounted parallel to its axis of rotation.

Bei Aufschneidmaschinen, die beispielsweise aus der WO 03/028963 A und der US-A- 6 123 002 bekannt sind werden heutzutage mit verhältnismäßig hohen Taktzahlen Scheiben von einem Lebensmittelriegel, beispielsweise einem Wurst-, Schinken- oder Käseriegel, abgetrennt. Die Lebensmittel liegen hierbei auf einer Produktauflage auf und werden von dieser schrittweise oder kontinuierlich gegen das Schneidmesser transportiert. Bei sehr hohen Schneidleistungen besteht die Notwendigkeit, Leerschritte, d. h. Bewegungen des Schneidmessers, bei denen keine Lebensmittelscheibe von dem Lebensmittelriegel abgetrennt wird, vorzusehen. Um Leerschnitte zu erzeugen, ist es zum einen möglich, das Lebensmittel durch einen von der Schneidebene weg gerichteten Rückzugshub zu realisieren. Weiterhin ist es möglich, einen Leerschnitt durch eine vorzugsweise axiale Verschiebung des Messers zu erzeugen.For slicing machines, for example, from the WO 03/028963 A and the US-A-6,123,002 Nowadays discs of a food bar, for example a sausage, ham or cheese bar, are separated with relatively high cycle numbers. The foodstuffs rest on a product support and are transported step by step or continuously against the cutting knife. At very high cutting performance, there is a need to blank, ie movements of the cutting blade, where no food disc is separated from the food bar, provide. In order to produce idle cuts, it is possible, on the one hand, to realize the food by means of a return stroke directed away from the cutting plane. Furthermore, it is possible to produce a blank cut by a preferably axial displacement of the knife.

Eine derartige axiale Verschiebung des Schneidmessers wird beispielsweise in der Patentschrift Nr. 15 49 52 gelehrt, wobei der axiale Rückzughub des Messers der dort beschriebenen Aufschneidemaschine durch eine mit dem Antrieb gekoppelte Kurvenscheibe realisiert wird, so dass eine axiale Verschiebung des Messer unabhängig von der Drehzahl des Messers nicht möglich ist. Eine weitere Aufschneidemaschine mit einem axial verschiebbaren Messer ist in der DE-US 4214264 A1 gelehrt, wobei in dem vorliegenden Fall die axiale Bewegung durch einen Stellzylinder erfolgt, so dass nur eine Bewegung zwischen zwei Endpunkten und nicht auf das jeweilige Produkt abgestimmt, möglich ist.Such axial displacement of the cutting blade is taught, for example, in the patent document no. 15 49 52, wherein the axial return stroke of the knife of the slicing machine described therein is realized by a cam coupled to the drive, so that an axial displacement of the blade regardless of the speed of the Messers is not possible. Another slicing machine with an axially displaceable knife is in the DE-US 4214264 A1 taught, in the present case, the axial movement is carried out by an actuating cylinder, so that only a movement between two end points and not matched to the respective product is possible.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Aufschneidemaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.The present invention is therefore based on the object of providing a slicing machine which does not have the disadvantages of the prior art.

Gelöst wird die Aufgabe erfindungsgemäß durch eine Aufschneidemaschine gemäß Anspruch 1. Bevorzugte Ausführungsformen der erfindungsgemäßen Aufschneidemaschinen sind in den Unteransprüchen beschrieben.The object is achieved according to the invention by a slicing machine according to claim 1. Preferred embodiments of slicing machines according to the invention are described in the subclaims.

Gegenstand der vorliegenden Erfindung ist eine Aufschneidemaschine zum Aufschneiden von Lebensmitteln, insbesondere von Wurst- , Fleisch- oder Käseriegeln mit einem rotierenden Schneidmesser, das parallel zu seiner Rotationsachse verschieblich gelagert ist, wobei sie ein Gegengewicht aufweist, das gegenläufig zu dem Schneidmesser verschiebbar ist.The present invention is a slicing machine for slicing food, especially sausage, meat or cheese bars with a rotating cutting blade, which is slidably mounted parallel to its axis of rotation, wherein it has a counterweight which is movable in opposite directions to the cutting blade.

Diese erfindungsgemäße Aufschneidemaschine hat den Vorteil, dass Beschleunigungskräfte bzw. -momente, die bei der axialen Verschiebung des Messers entstehen, ausgeglichen werden. Dadurch läuft die Aufschneidemaschine nahezu schwingungsfrei, so dass insbesondere das Maschinengestell wesentlich leichter ausgeführt werden kann. Des weiteren läuft das Schneidmesser wesentlich ruhiger, so dass präzisere Schnitte möglich sind. Durch eine separate Verstellung der Gegenmasse unabhängig von der axialen Verschiebung des Messers, können Kräfte und/oder Momente, annulliert werden, die beispielsweise durch Verschleiß- oder Schleif-bedingte Messerunwuchten entstehen. Diese Justage des Messers erfolgt nach dem Anbringen des Messers oder im Betrieb.This slicing machine according to the invention has the advantage that acceleration forces or moments, which arise during the axial displacement of the knife, are compensated. As a result, the slicing machine runs almost vibration-free, so that in particular the machine frame can be made much easier. Furthermore, the cutting blade runs much quieter, so that more precise cuts are possible. By a separate adjustment of the counterweight independent of the axial displacement of the blade, forces and / or moments can be canceled, for example, caused by wear or grinding-related Messerunwuchten. This adjustment of the knife is done after attaching the knife or during operation.

In einer bevorzugten Ausführungsform erfolgt die Verschiebung des Schneidmessers und des Gegengewichtes durch jeweils einen geregelten Antrieb. Dieser geregelte Antrieb hat den Vorteil, dass eine sehr exakte und sehr schnelle axiale Verschiebung des Schneidmessers und des Gegengewichtes möglich ist. Die Positionen des Schneidmessers relativ zu seinem Nullpunkt und des Gegengewichtes sind zu jedem Zeitpunkt bekannt. Durch diesen geregelten Antrieb kann die jeweilige axiale Verschiebung, insbesondere bezüglich Weg und Beschleunigung, auf den jeweiligen Anwendungsfall optimal angepasst werden. Das Optimum der Verschiebung des Schneidmessers ist u.a. eine Funktion der Schneidleistung, des Produktes, insbesondere der Produktgeometrie sowie der Temperatur des Produktes, der Messergeometrie, der Stellung des Messers zum Produkt und/oder der Scheibenstärke. Des weiteren ist es mit der Aufschneidemaschine möglich, unterschiedlichste Verschiebungsverläufe, beispielsweise sinuide Verläufe der axialen Verschiebung zu realisieren. Die optimale Verschiebung des Schneidmessers und des Gegengewichtes kann in einem der Schneidmaschine zugeordneten Computer abgespeichert werden. Die erfindungsgemäße Aufschneidemaschine ist einfach und kostengünstig herzustellen und zu betreiben.In a preferred embodiment, the displacement of the cutting blade and the counterweight is carried out by a respective regulated drive. This controlled drive has the advantage that a very accurate and very fast axial displacement of the cutting blade and the counterweight is possible. The positions of the cutting blade relative to its zero point and the counterweight are known at all times. By means of this controlled drive, the respective axial displacement, in particular with regard to travel and acceleration, can be optimally adapted to the respective application. The optimum displacement of the cutting blade is, inter alia, a function of the cutting performance of the product, in particular the product geometry as well as the temperature of the product, the knife geometry, the position of the knife to the product and / or the disk thickness. Furthermore, it is possible with the slicing machine to realize a wide variety of displacement profiles, for example, sinusoidal courses of the axial displacement. The optimum displacement of the cutting blade and the counterweight can be stored in a computer associated with the cutting machine. The slicing machine according to the invention is simple and inexpensive to manufacture and operate.

Vorzugsweise weist die Aufschneidemaschine jedoch nur einen vorzugsweise geregelten Antrieb für die Verschiebung des Schneidemessers und des Gegengewichtes auf. Diese Ausführungsform hat den Vorteil, dass für beide Bewegungen nur ein Antrieb nötig ist. Bezüglich der Vorteile eines geregelten Antriebs der Verschiebung wird auf das oben gesagte verwiesen.Preferably, however, the slicing machine only has a preferably controlled drive for the displacement of the cutting knife and the counterweight. This embodiment has the advantage that only one drive is necessary for both movements. With regard to the advantages of a controlled drive of the displacement, reference is made to the above.

Als Schneidmesser kommt jedes dem Fachmann bekannte Messer infrage. Beispielhaft seien hier nur das Kreismesser, das Spiralmesser und das Sichelmesser genannt. Das Kreismesser läuft vorteilhafterweise planetenartig um. Das Messer wird von einem Antrieb in Rotation versetzt. Vorzugsweise ist dieser Antrieb geregelt.As a cutting knife every known to the expert knife comes into question. By way of example, only the circular blade, the spiral blade and the sickle blade are mentioned here. The circular knife advantageously turns around like a planet. The knife is rotated by a drive. Preferably, this drive is regulated.

Als Gegengewicht eignet sich jedes Gewicht, mit dem die Annullierung der Beschleunigungskräfte bzw. Beschleunigungsmomente und/oder die Annullierung von Kräften bzw. Momenten bedingt durch Messerunwuchten und dergleichen, möglich ist. Der Fachmann erkennt, dass die Masse der Gegenmasse nicht der Masse des Schneidmessers entsprechen muss. Dasselbe gilt für den zeitlichen Beschleunigungsverlauf und den Verschiebungsweg der Gegenmasse, die nicht dem Beschleunigungsverlauf bzw. der axialen Verschiebung des Messers entsprechen müssen. Des weiteren erkennt der Fachmann, dass das Gegengewicht nicht symmetrisch, insbesondere nicht rotationssymmetrisch sein muss.As a counterweight is any weight with which the cancellation of the acceleration forces or acceleration moments and / or the cancellation of forces or moments caused by Messerunwuchten and the like, is possible. The person skilled in the art recognizes that the mass of the counterweight does not have to correspond to the mass of the cutting blade. The same applies to the temporal acceleration course and the displacement path of the counterweight, which need not correspond to the acceleration course or the axial displacement of the blade. Furthermore, the person skilled in the art recognizes that the counterweight does not have to be symmetrical, in particular not rotationally symmetrical.

Vorzugsweise erfolgt die Verschiebung des Messers und/oder des Gegengewichts zumindest weitestgehend spielfrei.Preferably, the displacement of the blade and / or the counterweight is at least largely free of play.

Vorzugsweise erfolgt die Verschiebung des Schneidmessers und/oder des Gegengewichtes unabhängig von der Drehzahl des Schneidmessers.Preferably, the displacement of the cutting blade and / or the counterweight is independent of the speed of the cutting blade.

In einer anderen bevorzugten Ausführungsform der erfindungsgemäßen Aufschneidemaschine weist das Schneidmesser eine Antriebswelle auf und das Schneidmesser und/oder das Gegengewicht sind entlang der Antriebswelle verschieblich gelagert. Die Antriebwelle weist vorzugsweise einen regelbaren Antrieb auf.In another preferred embodiment of the slicing machine according to the invention, the cutting blade has a drive shaft and the cutting blade and / or the counterweight are displaceably mounted along the drive shaft. The drive shaft preferably has a controllable drive.

Weiterhin bevorzugt erfolgt die Verschiebung des Schneidmessers und/oder des Gegengewichtes mit einer Spindel, die besonders bevorzugt innerhalb der Antriebswelle angeordnet ist. Diese Spindel ist vorzugsweise regelbar antreibbar und wirkt vorzugsweise mit dem Gewinde von mindestens einer Hülse(Mutter) zusammen, die mit dem Schneidmesser oder mit dem Gegengewicht verbunden ist. Vorzugsweise weist die Aufschneidemaschine jedoch zwei Hülsen auf, wobei eine mit dem Schneidemesser und eine mit dem Gegengewicht zusammenwirkt. Diese Hülsen haben vorzugsweise unterschiedliche Gewinde, wobei sich die Gewinde vorzugsweise in ihrer Gangrichtung und/oder in ihrem Steigungswinkel unterscheiden. Durch diese Ausführungsform der vorliegenden Erfindung wird mit einem Antrieb sowohl das Schneidmesser als auch das Gegengewicht verschoben. Vorzugsweise ist die Verbindung zwischen den Hülsen und der Spindel zumindest weitestgehend spielfrei. Dies kann beispielsweise durch eine Vorspannung der Hülsen erzielt werden, so dass diese immer an derselben Flanke der Spindel anliegen.Further preferably, the displacement of the cutting blade and / or the counterweight takes place with a spindle, which is particularly preferably arranged within the drive shaft. This spindle is preferably controllably drivable and preferably cooperates with the thread of at least one sleeve (nut), which is connected to the cutting blade or with the counterweight. Preferably, however, the slicing machine has two sleeves, one cooperating with the cutting knife and one with the counterweight. These sleeves preferably have different threads, wherein the threads preferably differ in their direction of travel and / or in their pitch angle. By this embodiment of the present invention, both the cutting blade and the counterweight are displaced by a drive. Preferably, the connection between the sleeves and the spindle is at least largely free of play. This can be achieved for example by a bias of the sleeves, so that they always rest on the same edge of the spindle.

Vorzugsweise ist der Verschiebemechanismus für das Messer und/oder für das Gegengewicht zwangstemperiert, vorzugsweise gekühlt. Ganz besonders bevorzugt ist zusätzlich der Antrieb des Schneidmessers und/oder dessen Lagerung zwangsgekühlt. Die jeweilige Temperierung kann durch Flüssigkeiten, vorzugsweise wässrige Flüssigkeiten oder Öl, und/oder Gas erfolgen.Preferably, the displacement mechanism for the knife and / or for the counterweight is forced temperature controlled, preferably cooled. Most preferably, the drive of the cutting blade and / or its storage is additionally forcibly cooled. The respective temperature control can be carried out by liquids, preferably aqueous liquids or oil, and / or gas.

Weiterhin wird eine Vorrichtung zum Aufschneiden von Lebensmitteln mit einem rotierenden Schneidmesser offenbart, das parallel zu seiner Rotationsachse verschiebbar ist, wobei die Verschiebung mit mindestens einem Mittel erfolgt, dass ein erstes und zweites Ende aufweist, die in ihrer Lage zueinander veränderbar sind.Furthermore, a device for slicing food with a rotating cutting blade is disclosed, which is displaceable parallel to its axis of rotation, wherein the displacement takes place with at least one means having a first and second end, which are mutually changeable in their position.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass es mit einem derart einfachen Mittel gelingt, das Messer zwischen zwei Positionen hin und her zu bewegen.It was extremely surprising for the skilled person and it was not to be expected that such a simple means would allow the knife to move back and forth between two positions.

Vorzugsweise ist das Mittel eine Koppelstange oder eine Blattfeder.Preferably, the means is a coupling rod or a leaf spring.

Weiterhin bevorzugt werden das erste und das zweite Ende des Mittels, beispielsweise der Kopplungsstange gegeneinander verdreht, so dass sich deren Länge bezogen auf die Rotationsachse reversibel verkürzt.Further preferably, the first and the second end of the means, for example, the coupling rod are rotated against each other, so that their length shortened reversibly relative to the axis of rotation.

In einer anderen bevorzugten Ausführungsform der Vorrichtung wird das Mittel, beispielsweise eine Blattfeder, gebogen und wieder entspannt.In another preferred embodiment of the device, the means, for example a leaf spring, is bent and relaxed again.

Im folgenden werden die Erfindungen anhand der Figuren 1 - 9 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein.In the following, the inventions are based on the Figures 1 - 9 explained. These explanations are merely exemplary and do not limit the general inventive concept.

Figur 8 und Figur 9 zeigen eine Vorrichtung zur axialen Verschiebung eines Messers. FIG. 8 and FIG. 9 show a device for the axial displacement of a knife.

Figur 1 zeigt eine Prinzipskizze der erfindungsgemäßen Aufschneidemaschine. Das aufzuschneidende Lebensmittel 1 liegt auf einer Auflage (nicht dargestellt), die an ihrem vorderen Ende eine Schneidleiste 15 aufweist. Das Messer 2, mit dem Lebensmittelscheiben von dem Lebensmittel 1 abgetrennt werden, weist eine Schneidkante 18 auf, die mit der Schneidleiste 15 während des Abtrennens der Lebensmittelscheiben zusammenwirkt. Das Messer 2 ist mittels einer Nabe 7 auf der Antriebswelle 5 axial verschieblich jedoch drehfest auf zwei Buchsen 19 gelagert. Die Antriebswelle 5 ist wiederum mit Lagern 10 an einem Maschinenrahmen 17 drehbar gelagert. Die Antriebswelle 5 wird mittels des Zahnriemenrades 11, das mit einem geregelten Antrieb (nicht dargestellt), beispielsweise einem Servomotor zusammenwirkt, angetrieben. Ebenfalls auf der Antriebswelle 5 ist das Gegengewicht 4 drehfest, jedoch axial verschieblich auf zwei Buchsen 19 gelagert. Innerhalb der Welle 5 befindet sich eine Spindel 6, die über das Zahnriemenrad 12 mit einem geregelten Antrieb (nicht dargestellt), in dem vorliegenden Fall ein Servomotor, verbunden ist. Auf der Spindel 6 sind die Hülsen 8 und 9 angeordnet, die jeweils über ein Innengewinde 13, 14 verfügen, das mit der Spindel 6 zusammenwirkt. Das Gewinde 13 ist ein Rechtsgewinde während das Gewinde 14 ein Linksgewinde ist. Des weiteren unterscheiden sich die Gewinde in ihrer Steigung. Der Fachmann erkennt, dass letzteres nicht der Fall sein muss. Die Hülse 8 ist mit der Nabe 7, an der das Messer 2 angeordnet ist, verbunden. Der Fachmann erkennt, dass die Nabe 7 und die Hülse 8 auch einstückig ausgeführt sein können. Die Hülse 9 ist mit dem Gegengewicht 4 verbunden. Auch hier ist eine einstückige Ausführung denkbar. Im Regelfall drehen sich die Welle 5 und die Spindel 6 während des Aufschneidens von Lebensmitteln gleich schnell, so dass sich die Hülsen 8,9 in einer stationären Lage relativ zu der Spindel 6 befinden. Wird eine axiale Verschiebung des Messers 2 und des Gegengewichtes 4 gewünscht, so wird die Drehzahl der Spindel 6 bzw. der Antriebswelle 5 so verändert, dass diese nicht mehr gleich schnell laufen, so dass sich die Hülsen 8, 9 relativ zu der Spindel 6 bewegen. Aufgrund der unterschiedlichen Drehrichtungen der Gewinde 13,14 der Hülsen 8, 9 bewegen sich das Schneidmesser und das Gegengewicht jeweils in unterschiedliche Richtungen, so dass sich Kräfte bzw. Momente aufheben, die durch die jeweiligen Bewegungen induziert werden. In dem vorliegenden Fall ist die Steigung des Gewindes 14 der Hülse 9 größer als die Steigung des Gewindes 13 der Hülse 8, so dass das Gegengewicht 4 kleiner als die Masse des Schneidmessers gewählt werden kann. Der Fachmann erkennt, dass das Gegengewicht 4 nicht rotationssymmetrisch sein muss, so dass mit dem Gegengewicht Unwuchten des Messers ausgeglichen werden können. Der Fachmann erkennt des weiteren, dass es auch möglich sein kann, dass das Gegengewicht 4 unabhängig von dem Schneidmesser entlang der Spindel bewegt werden kann. Da es sich bei dem vorliegende Fall nicht um ein rotationssymmetrisches Messer handelt, weist die Nabe 7 in ihrem oberen Bereich eine Auswuchtmasse 16' auf, an der zusätzlich ein Auswuchtmasse 16 angeordnet ist, um für eine Auswuchtung des Messers zu sorgen. Der Fachmann erkennt, dass die Auswuchtmassen 16, 16' rechts und links von dem Messer angeordnet sind, um ein Taumeln des Messers zu vermeiden. Der Fachmann erkennt außerdem, dass die Auswuchtmassen 16, 16' nicht unmittelbar an dem Messer angeordnet sein müssen. Beispielsweise ist es vorteilhaft, wenn das Messer 2 ohne die Auswuchtmassen 16, 16' axial verschoben wird. FIG. 1 shows a schematic diagram of the slicing machine according to the invention. The food to be sliced 1 is on a support (not shown) having a cutting bar 15 at its front end. The knife 2, with the food slices are separated from the food 1, has a cutting edge 18 which cooperates with the cutting bar 15 during the separation of the food slices. The knife 2 is by means of a hub 7 on the Drive shaft 5 axially displaceable but rotatably mounted on two bushings 19. The drive shaft 5 is in turn rotatably supported by bearings 10 on a machine frame 17. The drive shaft 5 is driven by means of the toothed belt wheel 11, which cooperates with a controlled drive (not shown), for example a servo motor. Also on the drive shaft 5, the counterweight 4 rotatably, but axially displaceably mounted on two bushings 19. Within the shaft 5 is a spindle 6, which is connected via the toothed belt wheel 12 with a controlled drive (not shown), in the present case a servo motor. On the spindle 6, the sleeves 8 and 9 are arranged, each having an internal thread 13, 14, which cooperates with the spindle 6. The thread 13 is a right-hand thread while the thread 14 is a left-hand thread. Furthermore, the threads differ in their pitch. The skilled person recognizes that the latter need not be the case. The sleeve 8 is connected to the hub 7, on which the knife 2 is arranged. The skilled artisan recognizes that the hub 7 and the sleeve 8 can also be made in one piece. The sleeve 9 is connected to the counterweight 4. Again, a one-piece design is conceivable. As a rule, the shaft 5 and the spindle 6 rotate during the slicing of food at the same speed, so that the sleeves are 8.9 in a stationary position relative to the spindle 6. If an axial displacement of the blade 2 and the counterweight 4 is desired, the speed of the spindle 6 or the drive shaft 5 is changed so that they no longer run at the same speed, so that the sleeves 8, 9 move relative to the spindle 6 , Due to the different directions of rotation of the threads 13,14 of the sleeves 8, 9, the cutting blade and the counterweight move in different directions, so that cancel forces or moments that are induced by the respective movements. In the present case, the pitch of the thread 14 of the sleeve 9 is greater than the pitch of the thread 13 of the sleeve 8, so that the counterweight 4 can be selected smaller than the mass of the cutting blade. The person skilled in the art recognizes that the counterweight 4 does not have to be rotationally symmetrical, so that imbalances of the blade can be compensated with the counterweight. The skilled person further recognizes that it may also be possible that the counterweight 4 can be moved independently of the cutting blade along the spindle. Since the present case is not a rotationally symmetric blade, the hub 7 is in its upper portion a balancing mass 16 'on which an additional balancing mass 16 is arranged in order to ensure balancing of the blade. The person skilled in the art recognizes that the balancing masses 16, 16 'are arranged on the right and left of the knife, in order to avoid tumbling of the knife. The skilled person also recognizes that the balancing masses 16, 16 'need not be arranged directly on the knife. For example, it is advantageous if the blade 2 is moved axially without the balancing masses 16, 16 '.

Da die beispielsgemäße Aufschneidemaschine geregelte Antriebe aufweist, kann dieser zur Einstellung des Nullpunktes des Schneidmessers eingesetzt werden. Dafür wird das Messer 2 zunächst einmal beabstandet von der Schneidleiste 15 angeordnet in eine Drehbewegung versetzt und langsam in Richtung der Schneidleiste 15 bewegt. Dabei wird beispielsweise das Drehmoment gemessen, das benötigt wird, um das Schneidmesser 2 konstant anzutreiben. Sobald dieses Drehmoment ansteigt, d. h. das Schneidmesser im Eingriff mit der Schneidleiste 15 steht, wird die axiale Bewegung des Messers gestoppt und ggf. inkremental umgekehrt. Die so gefundene Einstellung ist der neue Nullpunkt. Diese Ausführungsform hat den Vorteil, dass die Schneidleiste nicht wie beim Stand der Technik relativ zu dem Messer verschoben werden muss und dass die Nullpunktsfindung bei der erfindungsgemäßen Aufschneidemaschine automatisch erfolgen kann und während des Aufschneidvorgangs wiederholt werden kann. Der Nullpunkt wird von der erfindungsgemäßen Aufschneidemaschine in einer der Maschine zugeordneten Steuereinheit abgespeichert und kann zur Einstellung des Schneidspaltes herangezogen werden.Since the exemplary slicing machine has controlled drives, this can be used to set the zero point of the cutting blade. For this purpose, the knife 2 is initially spaced apart from the cutting bar 15 arranged in a rotational movement and slowly moved in the direction of the cutting bar 15. In this case, for example, the torque is measured, which is required to drive the cutting blade 2 constant. As soon as this torque increases, d. H. the cutting blade is in engagement with the cutting bar 15, the axial movement of the blade is stopped and optionally reversed incrementally. The setting thus found is the new zero point. This embodiment has the advantage that the cutting bar does not have to be moved relative to the knife as in the prior art and that the zero point finding can be done automatically in the slicing machine according to the invention and can be repeated during the slicing process. The zero point is stored by the slicing machine according to the invention in a control unit associated with the machine and can be used to adjust the cutting gap.

Des weiteren kann der geregelte Antrieb zur Einstellung bzw. Nachregelung der Spaltbreite eingesetzt werden. Der Fachmann erkennt, dass das Schneidmesser 2 schüsselartig geformt ist. Während des Betriebes des Schneidmessers 2 weitet sich dieses beispielsweise durch thermische Effekte und/oder Fliehkräfte auf. Der Grad der Aufweitung ist demnach unter anderem eine Funktion der Drehgeschwindigkeit des Schneidmessers und dem Fachmann entweder bekannt oder kann gemessen werden. Insbesondere bei einer Aufschneidemaschine, bei der die Drehzahl des Schneidmessers nicht konstant ist aber auch nach dem Kaltstart, kann die Aufweitung durch eine relative Bewegung zwischen Spindel und Antriebswelle ausgeglichen werden, so dass mit der erfindungsgemäßen Aufschneidemaschine während des gesamten Schneidvorganges mit einem konstanten Schneidspalt geschnitten werden kann und somit Lebensmittelscheiben mit einer sehr konstanten Dicke erzielbar sind. Durch automatische Ein- bzw. Nachstellung des Schneidspaltes kann mit wesentlich kleineren Schneidspalten als beim Stand der Technik geschnitten werden, was sich positiv auf die Schneidqualität auswirkt. Der Antrieb 5, 7 des Messers 2 und/oder der Verstellmechanismus 6, 8, 9 des Messers 2 und/oder des Gegengewichts 4 sind bei der vorliegende Aufschneidmaschine temperierbar, vorzugsweise kühlbar.Furthermore, the controlled drive can be used to adjust or readjust the gap width. The skilled artisan will recognize that the cutting blade 2 is bowl-shaped. During operation of the cutting blade 2, this expands, for example, by thermal effects and / or centrifugal forces. The degree of expansion is thus, inter alia, a function of the rotational speed of the cutting blade and the expert either known or can be measured. In particular, in a slicing machine in which the speed of the cutting blade is not constant but also after the cold start, the expansion by a relative movement between the spindle and the drive shaft be balanced so that can be cut with the slicing machine according to the invention during the entire cutting process with a constant cutting gap and thus food slices with a very constant thickness can be achieved. By automatic adjustment or adjustment of the cutting gap can be cut with much smaller cutting gaps than in the prior art, which has a positive effect on the cutting quality. The drive 5, 7 of the blade 2 and / or the adjusting mechanism 6, 8, 9 of the blade 2 and / or the counterweight 4 are temperature-controlled in the present slicing machine, preferably cooled.

Figur 2 zeigt eine weitere Prinzipskizze der erfindungsgemäßen Aufschneidemaschine mit einer Spindel 6. Die Aufschneidemaschine entspricht im wesentlichen der Aufschneidemaschine gemäß Figur 1, so dass die dort gemachten Ausführungen analog gelten. In dem vorliegenden Fall weist die Aufschneidemaschine jedoch eine Feder 20 auf, die mit den Hülsen 8, 9 zusammenwirkt und diese so vorspannt, dass deren Gewinde 13, 14 jeweils nur mit einer Flanke des Gewindes der Spindel zusammenwirkt. Dadurch wird das Spiel zwischen den Hülsen 13, 14 und der Spindel 6 zumindest weitestgehend reduziert. Des weiteren ist in dem vorliegenden Fall die Nabe 7 nicht auf Buchsen sondern auf Lamellen 21 gelagert. Die Lamellen verformen sich bei der axialen Verschiebung der Nabe 7. Die Lamellen können gleichzeitig die Funktion einer Axialfeder zur spielfreien Vorspannung der Hülse 8 übernehmen. Neben den dargestellten Lamellen mit umlaufenden Sicken, können auch beliebig geschlitzte Lamellen zum Einsatz kommen. Die Lagerung mit Lamellen hat den Vorteil, das keine Reibung und damit keine Wärme und kein Verschleiß auftritt, . Außerdem sind der vorliegenden Darstellung Details der Temperierung, vorzugsweise Kühlung zu entnehmen. Das Temperiermedium, in dem vorliegenden Fall Wasser, wird über die Kanäle 22 der Aufschneidemaschine zugeführt und dann in den Bereich geleitet, in dem die Lagerung des Messers sowie die Verschiebung des Messers 2 und des Gegengewichtes 4 erfolgt. Nachdem diese Bereiche temperiert worden sind, wird das Temperiermedium via der Kanäle 23 aus dem Aufschneidekopf herausgeleitet. FIG. 2 shows a further schematic diagram of the slicing machine according to the invention with a spindle 6. The slicing machine substantially corresponds to the slicing machine according to FIG. 1 , so that the statements made there apply analogously. In the present case, however, the slicing machine has a spring 20, which cooperates with the sleeves 8, 9 and biases them so that their threads 13, 14 cooperate in each case only with one flank of the thread of the spindle. As a result, the play between the sleeves 13, 14 and the spindle 6 is at least largely reduced. Furthermore, in the present case, the hub 7 is not mounted on bushes but on lamellae 21. The lamellae deform during the axial displacement of the hub 7. The lamellae can simultaneously assume the function of an axial spring for backlash-free bias of the sleeve 8. In addition to the lamellae with circumferential beads, slotted louvers can also be used. The storage with slats has the advantage that no friction and thus no heat and no wear occurs. In addition, details of the temperature, preferably cooling can be found in the present illustration. The tempering medium, in the present case water, is fed via the channels 22 of the slicing machine and then passed into the area in which the storage of the blade and the displacement of the blade 2 and the counterweight 4 takes place. After these areas have been tempered, the tempering is led out via the channels 23 from the slicing head.

Figur 3 zeigt eine Prinzipskizze der erfindungsgemäßen Aufschneidemaschine mit drei Spindeln. In dem vorliegenden Fall ist das Messer an einer Messerhalterung 24 angeordnet, die axial verschiebbar ist. Die Messerhalterung 24 weist eine Auswuchtmasse auf. Im Prinzip erfolgt die axiale Verschiebung der Messerhalterung wie in Figur 1 dargestellt, nur dass in dem vorliegenden Fall die axiale Verschiebung nicht durch eine sondern durch mindestens 3 Spindeln erfolgt, die jeweils mit zwei Hülsen zusammenwirkt, wobei die Spindeln drehfest angeordnet sind und die Hülsen 8, 9 (nur eine dargestellt) von dem Zahnrad 25 angetrieben wird. Eine Hülse hat ein Rechts- und eine ein Linksgewinde. Während des Betriebes drehen sich der von der Antriebswelle 5 angetriebene Rotor 26 und das Zahnrad 25 gleich schnell und in dieselbe Richtung. Zur axialen Verstellung der Messerhalterung 24 bzw. des Gegengewichtes 4 wird die Drehzahl des Zahnrades 25 oder des Rotors so verändert, dass sich die Spindel und damit die Messerhalterung 24 bzw. das Gegengewicht 4 in die gewünschte Richtung bewegt. Der Fachmann erkennt, dass auch die Spindel 6 antreibar und die Hülse 8, 9 drehfest sein können. Des weiteren erkennt der Fachmann, das jede Spindel 6 oder Hülse 8, 9 einzeln antreibbar sein kann. Auch in dem vorliegenden Fall ist der Verschiebemechanismus temperiert. Dafür wird ein Temperierungsmedium, vorzugsweise Wasser, durch den Kanal 22 und eine axiale Bohrung in jeder Spindel geführt und dann durch den Kanal 23 wieder abgeleitet. FIG. 3 shows a schematic diagram of the slicing machine according to the invention with three spindles. In the present case, the knife is attached to a knife holder 24 arranged, which is axially displaceable. The knife holder 24 has a balancing mass. In principle, the axial displacement of the knife holder takes place as in FIG. 1 shown, except that in the present case, the axial displacement is done not by one but by at least 3 spindles, which cooperates with two sleeves, the spindles are arranged rotationally fixed and the sleeves 8, 9 (only one shown) driven by the gear 25 becomes. A sleeve has a right-hand and a left-hand thread. During operation, the driven by the drive shaft 5 rotor 26 and the gear 25 rotate at the same speed and in the same direction. For axial adjustment of the knife holder 24 and the counterweight 4, the speed of the gear 25 or the rotor is changed so that the spindle and thus the knife holder 24 and the counterweight 4 moves in the desired direction. The person skilled in the art recognizes that the spindle 6 can also be driven in rotation and the sleeve 8, 9 can be rotationally fixed. Furthermore, the person skilled in the art recognizes that each spindle 6 or sleeve 8, 9 can be driven individually. Also in the present case, the displacement mechanism is tempered. For this purpose, a tempering medium, preferably water, is passed through the channel 22 and an axial bore in each spindle and then discharged through the channel 23 again.

In Figur 4 ist eine Vorrichtung zum Aufschneiden von Lebensmittelriegeln dargestellt. Die Lebensmittelriegel (nicht dargestellt) werden mit dem Transportband 32 in Richtung eines Messers 27 transportiert, das den Lebensmittelriegel in Lebensmittelscheiben aufschneidet. Das Messer 27 ist mit einer Welle 30 drehfest verbunden, die von einem Motor (nicht dargestellt) rotierend angetrieben wird. Das Messer 27 ist auf der Welle 30 axial verschieblich gelagert. Der Fachmann versteht, dass auch die Welle an sich axial verschieblich gelagert sein kann. Zwischen der Schneidebene 26 des Messers 27 und der Schneidleiste 28, mit der das Messer beim Schneiden zusammenwirkt, besteht ein Schneidspalt 29 , der einstellbar ist, und der für ein optimales Schneidergebnis möglichst klein sein sollte. Das Messer darf die Schneidleiste 28 beim Schneiden jedoch nicht berühren. Zur Einstellung des Schneidspaltes weist die erfindungsgemäße Vorrichtung einen Justieranschlag 31 auf, der sich in der vorliegenden Darstellung in seiner Grundstellung befindet, d. h. dass er von dem Messer vergleichsweise weit zurückgezogen ist. Der Justieranschlag 31 kann, wie durch den Doppelpfeil dargestellt, axial verschoben werden. Diese axiale Verschiebung kann manuell erfolgen, vorzugsweise erfolgt sie jedoch durch Einstellantrieb, der wiederum mit einer zentralen Steuereinheit verbunden ist, so dass beispielsweise auf dem Display der Maschine eine bestimmte Stellung des Justieranschlages und damit eine bestimmte Breite des Schneidspaltes vorgewählt werden kann. Die axiale Verschiebung des Justieranschlages in Richtung des Messers ist in dem vorliegenden Fall durch die Muttern 41 begrenzt. 4 Figur 5 zeigt die Vorrichtung zum Aufschneiden von Lebensmitteln gemäß Figur 4, wobei sich in dieser Figur der Justieranschlag in seiner Justierstellung befindet; d. h. er ist von dem Stellantrieb oder manuell nach links zum Messer hin bewegt worden.In FIG. 4 a device for slicing food bars is shown. The food bars (not shown) are transported with the conveyor belt 32 in the direction of a knife 27, which cuts the food bar into food slices. The knife 27 is rotatably connected to a shaft 30 which is driven in rotation by a motor (not shown). The knife 27 is mounted on the shaft 30 axially displaceable. The skilled person understands that the shaft itself can be mounted axially displaceable. Between the cutting plane 26 of the knife 27 and the cutting bar 28, with which the knife cooperates during cutting, there is a cutting gap 29, which is adjustable, and which should be as small as possible for an optimum cutting result. However, the knife must not touch the cutter bar 28 when cutting. To set the cutting gap, the device according to the invention has an adjusting stop 31, which in the present representation is in its basic position, ie that it is relatively far removed from the knife. The adjustment stop 31 can, as by the double arrow shown, moved axially. This axial displacement can be done manually, but preferably it is done by adjusting drive, which in turn is connected to a central control unit, so that for example on the display of the machine a certain position of the Justieranschlages and thus a certain width of the cutting gap can be preselected. The axial displacement of the Justieranschlages in the direction of the knife is limited in the present case by the nuts 41. 4 FIG. 5 shows the device for slicing food according to FIG. 4 , In this figure, the adjustment stop is in its adjustment position; ie it has been moved by the actuator or manually to the left towards the knife.

Nachdem der Justieranschlag nach links bewegt worden ist, wird das Messer, wie in Figur 6 dargestellt, axial nach rechts verschoben, bis es den Justieranschlag berührt. Die axiale Verschiebung des Messers erfolgt in dem vorliegenden Fall durch einen Motor. Die Berührung von dem Messer und dem Justieranschlag kann beispielsweise durch einen Berührungssensor, der sich in dem Justieranschlag befindet, oder durch die Stromaufnahme des Motors, der das Messer axial verschiebt, detektiert werden. Sobald das Messer den Justieranschlag berührt hat, weist der Schneidspalt 29 die gewünschte Breite auf und der Justieranschlag kann, wie in Figur 7 dargestellt, wieder in seine Grundstellung zurückverfahren werden.After the adjustment stop has been moved to the left, the knife becomes as in FIG. 6 shown, moved axially to the right until it touches the adjustment stop. The axial displacement of the blade takes place in the present case by a motor. The touch of the knife and the adjusting stop can be detected, for example, by a touch sensor located in the adjusting stop or by the current drawn by the motor which axially displaces the knife. Once the knife has touched the Justieranschlag, the cutting gap 29 has the desired width and the Justieranschlag can, as in FIG. 7 be restored to its basic position.

Die Einstellung des Justierspaltes kann vor dem Aufschneiden eines neuen Lebensmittelriegels und/oder nach einem Messerwechsel erfolgen. Mit der Vorrichtung ist es möglich, den Schneidspalt bei stillstehendem oder auch bei einem rotierenden Messer einzustellen. Die Einstellung bei einem rotierenden Messer hat den Vorteil, dass Veränderungen der Schneidebene, beispielsweise durch Fliehkräfte oder thermische Einflüsse kompensiert werden können.The adjustment of the adjustment gap can be done before cutting a new food bar and / or after a knife change. With the device, it is possible to set the cutting gap at a standstill or even with a rotating knife. The setting with a rotating knife has the advantage that changes in the cutting plane, for example by centrifugal forces or thermal influences can be compensated.

In Figur 8 ist eine weitere Aufschneidemaschine dargestellt. Bei Aufschneidmaschinen werden heutzutage mit verhältnismäßig hohen Taktzahlen Scheiben von einem Lebensmittelriegel, beispielsweise einem Wurst-, Schinken- oder Käseriegel, abgetrennt. Die Lebensmittel liegen hierbei auf einer Produktauflage auf und werden von dieser schrittweise oder kontinuierlich gegen das Schneidmesser transportiert. Bei sehr hohen Schneidleistungen besteht die Notwendigkeit, Leerschritte, d. h. Bewegungen des Schneidmessers, bei denen keine Lebensmittelscheibe von dem Lebensmittelriegel abgetrennt wird, vorzusehen. Derartige Leerschnitte werden beispielsweise durch eine vorzugsweise axiale Verschiebung des Messers erzeugt. Insbesondere die axiale Verschiebung des Messers ist in Figur 8 dargestellt. Die dort dargestellt Vorrichtung weist ein rotierendes Messer 2 auf, das mit einer Schneidleiste 28 zusammenwirkt. Das Messer 27 ist drehfest an dem linken Ende der Welle 30 gelagert. Die Welle 30 weist an ihrem rechten Ende ein Mittel 40 auf, das direkt oder indirekt mit einem Motor verbunden ist, der die Welle 30 antreibt. Des weiteren weist die erfindungsgemäße Vorrichtung Koppelstangen 33 auf, die mittels Kugelgelenken an ihren beiden Enden 34, 35 mit Aufnahmeringen 36, 37 verbunden sind. Der Aufnahmering 36 ist drehfest, jedoch axial verschieblich auf der Welle 30 gelagert. Der Aufnahmering 37 ist drehbar auf der Welle 30 gelagert und wird durch das Mittel 39, das direkt oder indirekt mit einem Motor verbunden ist, angetrieben. In dem dargestellten Beispiel sind die Mittel 39 und 40 synchron gesteuert. Da sich die Kopplungsstangen 33 in einer vertikalen Position befinden, ist der Abstand zwischen dem Messer 27 und der Schneidleiste 28 in der vorliegenden Figur größtmöglich. In dieser Position des Messers werden Leerschnitte erzeugt.In FIG. 8 Another cutting machine is shown. With slicing machines, slices of a food bar, for example a sausage, ham or cheese bar, are separated today with relatively high cycle numbers. The food is here on a product edition on and are transported by this gradually or continuously against the cutting blade. At very high cutting performance, there is a need to blank, ie movements of the cutting blade, where no food disc is separated from the food bar, provide. Such idle cuts are generated for example by a preferably axial displacement of the knife. In particular, the axial displacement of the blade is in FIG. 8 shown. The device shown there has a rotating knife 2, which cooperates with a cutting bar 28. The knife 27 is rotatably mounted on the left end of the shaft 30. The shaft 30 has at its right end a means 40 which is connected directly or indirectly to a motor which drives the shaft 30. Furthermore, the device according to the invention coupling rods 33 which are connected by means of ball joints at its two ends 34, 35 with receiving rings 36, 37. The receiving ring 36 is rotatably, but axially displaceably mounted on the shaft 30. The receiving ring 37 is rotatably mounted on the shaft 30 and is driven by the means 39 which is directly or indirectly connected to a motor. In the illustrated example, means 39 and 40 are synchronously controlled. Since the coupling rods 33 are in a vertical position, the distance between the knife 27 and the cutting bar 28 in the present figure is greatest possible. In this position of the knife, gaps are created.

In Figur 9 ist ein Zustand dargestellt, nachdem die Koppelstangen 33 verdreht worden sind. Dadurch, dass die axiale Länge bezogen auf die Rotationsachse durch die Drehung reversibel verkürzt worden ist, wird der Aufnahmering 36 und damit das Messer 27 axial in Richtung der Schneidleiste 28 zurückgezogen. Der Abstand zwischen der Schneidebene und dem Messer entspricht jetzt dem gewünschten Schneidspalt und Lebensmittelscheiben werden von dem Lebensmittelriegel abgetrennt.In FIG. 9 a state is shown after the coupling rods 33 have been twisted. Due to the fact that the axial length has been reversibly shortened relative to the axis of rotation by the rotation, the receiving ring 36 and thus the knife 27 are retracted axially in the direction of the cutting bar 28. The distance between the cutting plane and the knife now corresponds to the desired cutting gap and food slices are separated from the food bar.

Die Verdrehung der Koppelstangen erfolgt durch eine kurzzeitige Änderung der Drehzahl des Mittels 39 im Vergleich zur Drehzahl des Mittels 40, wobei die Drehzahländerung so erfolgen muss, dass entweder die ,Drehzahl des Mittels 39 im Vergleich zur Drehzahl des Mittels 40 verlangsamt oder dass die Drehzahl des Mittels 40 im Vergleich zur Drehzahl des Mittel 39 vergrößert wird. Nach der Beendigung der Verdrehung drehen die beiden Mittel 39, 40 wieder gleich schnell. Ein größerer Abstand zwischen dem Messer 27 und der Schneidleiste 28 kann wieder dadurch erreicht werden, dass die Koppelstangen 33 in eine vertikale Position gebracht werden. Dies erfolgt entweder dadurch, dass die Drehzahl des Mittels 39 kurzzeitig beschleunigt und/oder dass die Drehzahl des Mittels 40 kurzzeitig verlangsamt wird.The rotation of the coupling rods is effected by a short-term change in the speed of the means 39 compared to the speed of the means 40, wherein the speed change must be such that either the speed of the means 39 slows down compared to the speed of the means 40 or that the speed of the By means of 40 compared to the speed of the means 39 is increased. After Completion of the rotation turn the two means 39, 40 again at the same speed. A greater distance between the knife 27 and the cutting bar 28 can be achieved again by bringing the coupling rods 33 into a vertical position. This is done either by the fact that the speed of the means 39 accelerated for a short time and / or that the speed of the means 40 is slowed down for a short time.
