Description

Die vorliegende Erfindung betrifft ein Verfahren zum Aufschneiden von einem einem Messer zugeführten Lebensmittelriegel. Des weiteren betrifft die vorliegende Erfindung eine Vorrichtung zum Abtrennen von Lebensmittelscheiben.The present invention relates to a method of slicing a food bar supplied to a knife. Furthermore, the present invention relates to a device for separating food slices.

Mit Hochlelstungsaufschneidemaschinen, sogenannten "Slicern", sind beispielsweise aus der WO 00/59689 , der US 5,628,237 , der FR 2677573 sowie der DE 19525742 bekannt und werden stangenförmige Lebensmittel, beispielsweise Wurst, Käse oder dergleichen mit einer sehr hohen Schneidleistung in Scheiben geschnitten. Dabei wird die Lebensmittelstange mittels eines geregelten Antriebs durch eine ortsfeste schneldebene, in der der Schnitt durch ein schnell bewegtes Messer erfolgt, transportiert Die Scheibenstärke ergibt sich aus der Vorschubstrecke des Lebensmittelriegels zwischen zwei Schnitten. Demnach erfolgt bei einer konstanten Messergeschwindigkeit die Regelung der Schelbenstärke Ober die Vorschubgeschwindigkeit des Lebensmitteirlegels. Die geschnittenen Scheiben werden in der Regel mit konstanter Scheibenzahl zu Portionen zusammengefasst und verpackt. Das Gewicht dieser Portion soll möglichst genau eingehalten werden. Über die Schelbenstärke kann das Gewicht regelungstechnisch mittels der Vorschubgeschwindigkeit beeinflusst werden. Bei Slicem werden heutzutage aus Leistungsgründen oftmals mehrere Produktstangen nebeneinander durch ein Messer aufgeschnitten. Der Stand der Technik kennt sowohl kontinuierlich als auch diskontinulerlich beschickte Maschinen.With Hochlelstungsaufschneidemaschinen, so-called "slicers", for example, from WO 00/59689 , of the US 5,628,237 , of the FR 2677573 as well as the DE 19525742 known and bar-shaped foods, such as sausage, cheese or the like are cut with a very high cutting performance in slices. The food bar is transported by means of a controlled drive through a fixed Schneldebene, in which the cut is made by a fast-moving knife, the slice thickness results from the feed distance of the food bar between two cuts. Accordingly, at a constant knife speed, the regulation of the Schelbenstärke Ober the feed rate of Lebensjitteirlegels. The cut slices are usually combined into portions with constant number of plates and packaged. The weight of this portion should be kept as accurate as possible. About the Schelbenstärke the weight can be influenced control technology by means of the feed rate. Slicem nowadays often cut several product bars side by side by a knife for performance reasons. The prior art knows both continuously and discontinuously loaded machines.

Bei den kontinuierlich beschickten Aufschneidemaschinen besteht die Vorschubeinrichtung des Lebensmittelriegels in der Regel aus mehreren, vorzugsweise zwei, Förderbändern, zwischen denen die Lebensmittelstangen eingeklemmt und über Haftreibung durch die Schneidebene gefördert werden. Die Förderbänder sind einlaufseitig offen, so dass das Folgeprodukt stirnseitig das Ende des im Ausschnitt befindlichen Produktes berühren kann und damit ein annähernd kontinuierlicher Schneidprozess stattfindet. Nachteilig an diesem System ist, dass gegen Ende des Aufschneidprozesses des Produktes der Produktrest des Lebensmittelriegels nicht mehr test genug zwischen den Transportbändern einspannbar ist, so dass er oftmals durch das Messer herausgerissen und weggeschleudert wird.In the continuously loaded Aufschneidemaschinen the feed device of food bar usually consists of several, preferably two, conveyor belts, between which the food sticks are clamped and promoted by static friction through the cutting plane. The conveyor belts are open on the inlet side, so that the secondary product can touch the end of the product located in the cutout on the front side and thus an approximately continuous cutting process takes place. A disadvantage of this system is that towards the end of the slicing process of the product of the product of the Food bar is no longer test enough between the conveyor belts is clamped so that it is often torn out by the knife and thrown off.

Bei den diskontinuierlich beschickten Aufschneidemaschtnen wird die Produktstange, auch Lebensmittelriegel genannt an seinem dem Messer abgewandten Ende von einem Greifer erfasst und von diesem in Richtung des Messers transportiert. Diese Aufsehneidemaschinen haben beispielweise den Nachteil, dass sehr lange Lebensmittelniegel auf diesen Maschinen nicht bearbeitet werden können und dass beim Aufschneiden von mehreren parallelen Lebensmittelriegeln und mechanisch fest verbundenen Gretfem die Lebenemilttelriegel vor dem Aufschneiden teilweise stark komprimiert werden.In the discontinuously loaded Aufschneidemashchtnen the product bar, also called food bar is detected at its end facing away from the knife by a gripper and transported by this in the direction of the knife. These chewing machines, for example, have the disadvantage that very long food seal on these machines can not be processed and that when slicing several parallel food bars and mechanically fixed Gretfem the Lebenmilttelriegel be partially compressed before cutting.

Es war deshalb die Aufgabe der vorliegenden Erfindung, Verfahren zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweisen. EP-A-0 930 137 offenbart ein Verfahrend gemäß Oberbegriff des Patentanspruchs 1 US 5,628,237 offenbart eine Vorrichtung gemäß Oberbegriff des Patentanspruchs 7. Gelöst wird die Aufgabe mit einem Verfahren gemäß Patentanspruch 1 und mit eine Vorrichtung gemäß Anspruch 7.It was therefore the object of the present invention to provide methods which do not have the disadvantages of the prior art. EP-A-0 930 137 discloses a method according to the preamble of claim 1 US 5,628,237 discloses a device according to the preamble of claim 7. The object is achieved with a method according to claim 1 and with a device according to claim 7.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass mit dem erfindungsgemäßen Verfahren Lebensmittelriegel beliebiger Länge aufgeschnitten werden können. Das erfindungsgemäße Verfahren ist auf vergleichsweise kleinen Aufschneidemaschinen durchzuführen, weil das Mittel beispielsweise ein Greifer erst zu einem vergleichsweise späten Zeltpunkt mit dem Lebensmittelriegel in Kontakt gebracht werden muss.It was extremely surprising for the person skilled in the art and it was not to be expected that food bars of any length could be cut open with the method according to the invention. The method according to the invention is to be carried out on comparatively small slicing machines, because the means, for example a gripper, only has to be brought into contact with the food bar at a comparatively late point in time.

Das Mittel, das mit dem dem Messer abgewandten Enden der Lebensmittelriegel in Kontakt gebracht wird, kann ein beliebiges dem Fachmann bekanntes Mittel sein. Beispielsweise und bevorzugt ist das Mittel ein Greifer, dessen Krallen in die Lebensmittelriegel gedrückt werden, oder die einen sonstigen, vorzugsweise reversiblen Form-, Kraft- undloder Formschluss mit dem Lebensmittelriegel eingehen.The means which is brought into contact with the ends of the food bars facing away from the knife may be any means known to those skilled in the art. For example, and preferably, the means is a gripper whose claws in the Food bars are pressed, or enter into another, preferably reversible form, force andlor positive fit with the food bar.

Vorzugweise worden mehrere Lebensmittelriegel parallel aufgeschnitten.Preferably, several food bars were cut in parallel.

Vorzugsweise werden die vorderen Enden der Lebensmittelriegel so angeordnet , dass sie sich vor dem ersten Schnitt auf einer Ebene im wesentlichen parallel zu der Schneldebene des Messers befinden, so dass kein Trimmschnitt durchgeführt werden muss.Preferably, the front ends of the food bars are arranged so that they are located on a plane substantially parallel to the Schneldebene of the knife before the first cut, so that no trimming cut must be performed.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass es mit dem bevorzugten Verfahren gelingt, mehrere Lebensmittelriegel parallel aufzuschneiden, ohne dass Trimmschnitte durchgeführt werden müssen. Das erfindungsgemäße Verfahren ist einfach und kostengünstig durchzuführen.It was extremely surprising for the expert and not to be expected to succeed with the preferred method of paralleling several food bars cut without trimming cuts. The inventive method is simple and inexpensive to perform.

Vorzugsweise ist das Mittel beispielsweise ein Greifer mit dem Lebensmittelriegel kraft-, form- und/oder stoffschlüssig sowie reversibel verbunden werden.Preferably, the means, for example, a gripper with the food bar force, form and / or cohesively and reversibly connected.

Weiterhin bevorzugt erfolgt die Verbindung zwischen dem Mittel vor oder besonders bevorzugt nach dem Beginn das Aufschneidens. Eine Verbindung des Mittels beispielsweise eines Greifers nach dem Beginn des Aufschneidens hat den Vorteil, dass Lebensrmittelriegel beliebiger Länge aufgeschnitten werden können. Die Verbindung zwischen dem Mittel und dem Lebensmittelriegel erfolgt beispielsweise kurz bevor sich das hintere Ende des Lebensmittelriegels im Bereich der Transportmittel befindet oder kurz bevor der Lebensmittelriegel soweit aufgeschnitten ist, dass ein sicherer Halt zwischen den Transportbändern nicht mehr gewährleistet ist.Further preferably, the connection between the agent before or particularly preferably after the start of the slicing occurs. A compound of the agent, for example, a gripper after the start of slicing has the advantage that food bars of any length can be cut open. The connection between the agent and the food bar takes place, for example, shortly before the rear end of the food bar is in the area of the means of transport or just before the food bar is cut so far that a secure hold between the conveyor belts is no longer guaranteed.

In einer anderen bevorzugten Ausführungsform wird das Mittel nach dem Aufschneiden aus der Vorschubtrasse entfernt. Vorzugsweise erfolgt dies durch ein Zurückziehen des Mittels aus der Vorschubtrasse. In einer anderen bevorzugten Ausführungsform wird das Mittel so aus der Vorschubtrasse entfernt, dass ein möglichst geringer Zeitverlust entsteht Dies erfolgt vorzugsweise durch ein Bewegung des Mittels quer zur Vorschubtrasse.In another preferred embodiment, the means is removed after cutting from the feed path. This is preferably done by retracting the agent from the feed path. In another preferred embodiment, the agent is removed from the feed path such that the least possible loss of time occurs. This is preferably done by a movement of the means transverse to the feed path.

In einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung wird die Verbindung zwischen den Mitteln und den Lebensmittelriegeln nach Beendigung des Aufschneidens mindestens eines Lebensmittelriegels gelöst Dies bedeutet, dass es vorteilhaft sein kann, dass das Aufschneiden der anderen Lebensmittelriegel die noch nicht nahezu vollständig aufgeschnitten sind, ebenfalls gelöst wird und die diese Endstücke einer Restverwertung zugeführt werden. Diese Verfahrensweise führt zu einer vergleichsweise hohen durchschnittlichen Aufschneideleistung. In einer anderen bevorzugten Ausführungsform der vorliegenden Erfindung wird jeder Lebensmtttelriegel maximal aufgeschnitten und daraus resultierende unvollständige Portionen mit nachfolgend aufzuschneidenden Lebensmittelriegeln ergänzt Diese Verfahrensweise führt zu einer maximalen Materialausnutzung, Der Betreiber kann zwischen diesen beiden Betriebsarten jederzeit wählen und sie beispielsweise dem jeweils aufzuschneidenden Produkt anpassen.In a further preferred embodiment of the present invention, the connection between the agents and the food bars is achieved after the slicing of at least one food bar has been completed. This means that it may be advantageous that the slicing of the other food bars that have not yet been almost completely sliced is also solved is and these end pieces are recycled. This procedure leads to a comparatively high average slicing performance. In another preferred embodiment of the present invention, each Lebensmtttelriegel is cut maximum and resulting incomplete portions with nachzuschneidenden food bars added This procedure leads to a maximum material utilization, the operator can choose between these two modes at any time and adjust them, for example, the product aufzuschneidenden.

Erfindungsgemäß wird das Mittel zumindest zeitweise ausschließlich durch die Transportmittel, vorzugsweise Transportbänder, die die Lebensmittelriegel in Richtung des Messers transportleren und/oder den Lebensmittelriegel selbst angetrieben; d.h. in Richtung des Messers bewegt. Dies bedeutet dass das Mittel beispielsweise ein Greifer zeitweise keinen eigenen Antrieb aufweist. Die Bewegung des Greifers in Richtung des Messers erfolgt demnach beispielsweise dadurch, dass er mit dem Lebensmittelriegel kraftschlüssig verbunden ist. Weiterhin kann der Transport dadurch erfolgen, dass sich ein Kraftschluss beispielsweise ein Reibschluss zwischen dem Mittel und den Transportbändern, die auch den Lebensmittelriegel transportieren, einstellt und das Mittel dadurch in Richtung des Messers transportiert wird. Diese Ausführungsform des erfindungsgemäßen Verfahrens hat den Vorteil, dass die Mittel nur angetrieben und die Antriebe nur geregelt werden müssen, um einen Kontakt zwischen dem Mittel und dem Lebensmittelriegal herzustellen und gegebenenfalls später um die Mittel aus der Vorschubtrasse zu entfernen. Zumindest in der Zeit dazwischen wird das Mittel nicht selbständig angetrieben.According to the invention, the means is at least temporarily exclusively by the transport, preferably conveyor belts that transport the food bars in the direction of the knife and / or the food bar itself driven; ie moved in the direction of the knife. This means that the means, for example, a gripper temporarily has no own drive. The movement of the gripper in the direction of the knife is thus for example, characterized in that it is positively connected to the food bar. Furthermore, the transport can take place in that adjusts a frictional connection, for example, a frictional engagement between the means and the conveyor belts, which also transport the food bar, and the agent is thereby transported in the direction of the knife. This embodiment of the method according to the invention has the advantage that the means only driven and the drives must be controlled only to establish contact between the agent and the food war and possibly later to remove the means from the feed path. At least in the meantime, the means will not be driven independently.

Ein weiterer Gegenstand der vorliegenden Erfindung ist eine Vorrichtung gemäß Anspruch 7.Another object of the present invention is a device according to claim 7.

Die Mittel, die mit dem dem Messer abgewandten Enden der Lebensmittelriegel in Kontakt gebracht werden, können beliebige dem Fachmann bekannte Mittel sein. Beispielsweise und bevorzugt sind die Mittel Greifer, deren Krallen in die Lebensmittelriegel gedrückt werden, oder die einen sonstigen, vorzugsweise reversible Form-, Kraft undloder Formschluss mit dem Lebensmittelriegel eingehen. Ein Mittel im Sinne der Erfindung ist jedoch auch eine Produktverlängerung, die weiter unten beschrieben ist.The means which are brought into contact with the ends of the food bars facing away from the knife can be any means known to those skilled in the art. By way of example and preferably, the means are grippers whose claws are pressed into the food bars or which enter into another, preferably reversible, shape, force and / or positive connection with the food bar. However, a means according to the invention is also a product extension, which is described below.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass die erfindungsgemäße Vorrichtung einfach und kostengünstig herzustellen ist. Des weiteren ist die erfindungsgemäße Vorrichtung einfach und kostengünstig zu betreiben, weil die Mittel nur zeitweise oder gar nicht selbständig angetrieben werden müssen.It was extremely surprising for the person skilled in the art and it was not to be expected that the device according to the invention would be simple and inexpensive to produce. Furthermore, the device according to the invention is simple and inexpensive to operate, because the funds must be driven only temporarily or not at all independently.

Erfindungsgemäß werden mindestens zwei Lebensmittelriegel jeweils mit mindestens einem Transportmittel in Richtung des Messers transportiert und ihr hinteres Ende zumindest zeitweise mit jeweils einem Mittel In Kontakt gebracht, wobei das Mittel an einer zentralen Einheit zumindest zeitweise jeweils verschieblich gelagert sind.According to the invention, at least two food bars are each transported with at least one transporting means in the direction of the knife and their rear end at least temporarily brought into contact with a respective means, wherein the means are mounted on a central unit at least temporarily displaceable.

Vorzugsweise ist an den Mitteln jeweils ein Geber angeordnet, mit dem ihre Lage relativ zu der zentralen Einheit feststellbar ist.Preferably, an encoder is arranged on the means, with their position relative to the central unit can be determined.

im folgenden wird die Erfindung anhand der Figuren 1-4 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erflndungsgedanken nicht ein. Die gemachten Ausführungen gelten sowohl für das erfindungsgemäße Verfahren als auch für die erfindungsgemäße Vorrichtung Figur 1 zeigt eine Aufschneidemaschine mit einer nahezu kontinuierlicnen Förderung des Produktes.

in the following the invention will be described with reference to Figures 1-4 explained. These explanations are merely exemplary and do not limit the general idea of the invention. The statements made apply both to the method according to the invention and to the device according to the invention FIG. 1 shows a slicer with a nearly continuous promotion of the product.

Figur 1 zeigt eine Aufschneidemaschine, die nahezu kontinuierlich beschickt wird. Die Aufschneidemaschine 5 weist ein Messer 11 auf, das ein Lebenamittelriegel 2 in Lebensmittelscheiben 12 schneidet. In der Regel werden die aufgeschnittenen Lebensmittelscheiben 12 zu Portionen konfiguriert und danach verpackt. Der Fachmann erkennt, dass mehrere Lebensmittelriegel gleichzeitig aufgeschnitten werden können. Die Lebensmittelriegel 2 werden mit zwei Förderbändern 4 kontinuierlich in Richtung der Schneidebene 6 des Messers 11 transportiert. Die Scheibenstärke ergibt sich aus der Vorschubstrecke des Lebensmittelriegels zwischen zwei Schnitten. Bei konstanter Messergesohwindigkeit erfolgt die Regelung der Scheibenstärke über die Vorschubgeschwindigkeit des Lebensmittelriegels. Die Förderbänder 4 sind einlaufseitig offen, so dass das Folgeprodukt stirnseltig das Ende des Im Aufschnitt befindlichen Produktes berühren kann und damit ein annähernd kontinuierlicher Schneidprozess stattfindet FIG. 1 shows a slicer that is fed almost continuously. The slicing machine 5 has a knife 11, which cuts a Lebenamittelriegel 2 in food slices 12. In general, the sliced food slices 12 are configured into portions and then packaged. The person skilled in the art recognizes that several food bars can be cut open at the same time. The food bars 2 are transported with two conveyor belts 4 continuously in the direction of the cutting plane 6 of the blade 11. The slice thickness results from the feed distance of the food bar between two cuts. At constant knife speed, the slice thickness is controlled by the feed speed of the food bar. The conveyor belts 4 are open on the inlet side, so that the secondary product can touch the end of the product being sliced in a continuous manner and thus an approximately continuous cutting process takes place

Die Figuren 2a und 2b zeigen eine erfindungsgemäße Aufschneidemaschine in zwei Ansichten. In Figur 2a ist der Messerkopf dargestellt, an dem sich das Messer 11 befindet mit dem Lebensmittelilegel 2 in Lebensmittelscheiben 12 aufgeschnitten werden. Der Lebensmittelriegel 2 wird von den Förderbändern 4 entlang der Vorschubtrasse 14 in Richtung des Messers transportiert. An seinem hinteren Ende ist der Lebensmittelriegel mit einem Greifer 18 in Kontakt gebracht worden, dessen eigner Antrieb 20,21 in Figur 2b detailliert dargestellt ist. Zwischen dem Greifer 18 und den Transportbändern 4 besteht ein Reibschluss, so dass der Greifer, sobald mit den Transportbändern im Eingriff steht von diesen und nicht von dem Antrieb 20. 21 in Richtung des Messers transportiert wird. Dementsprechend dient der Greifer nur zum Halten nicht jedoch zum Antreiben des Lebensmittelriegels.The Figures 2a and 2b show a slicing machine according to the invention in two views. In FIG. 2a the cutter head is shown, on which the knife 11 is cut with the food sirloin 2 in food slices 12. The food bar 2 is transported by the conveyor belts 4 along the feed path 14 in the direction of the knife. At its rear end, the food bar has been brought into contact with a gripper 18 whose own drive 20,21 in FIG. 2b is shown in detail. Between the gripper 18 and the conveyor belts 4 is a frictional engagement, so that the gripper, as soon as the conveyor belts engaged by these and not by the drive 20. 21 is transported in the direction of the knife. Accordingly, the gripper is only for holding but not for driving the food bar.

Figur 2b zeigt die Aufschneidemaschine gemäß Figur 2a in einer Draufsicht, wobei die Förderbänder 4 aus Übersichtsgründen weggelassen wurden. Die vorliegende beispielhafte Aufschneidemaschine eignet sich zum Aufschneiden vom vier parallel in einer Ebene angeordneten Lebensmittelriegeln. Dementsprechend hat die Aufschneidemaschine vier Greifer 18, die jeweils mit einem Lebensmittelriegel in Kontakt gebracht werden und deren Krallen 7 dabei in den Lebensmittelriegel (nicht dargestellt) gefahren werden. Die Greifer 18 sind an einer zentralen Einheit 20 angeordnet, die entlang einer Führung 22 verschiebbar ist. Die Verschiebung der zentralen Einheit 20 kann entweder durch einen Motor oder durch die Lebensmittelriegel, die mit den Greifern verbunden sind und die mittels der Transportbänder 4 in Richtung des Messers transportiert werden, oder durch die Transportbändern erfolgen. Die Einheit 20 kann auch in ihrer Lage relativ zur Führung 22 fixiert werden. Jeder Greifer 18 weist des weiteren einen Antrieb 21 auf, mit dem der Greifer relativ zu der zentralen Einheit 20 bewegbar oder fixierbar ist. Dieser Antrieb 21 kann so umgestellt werden, dass er als oder ähnlich wie ein Loslager funktioniert, d. h. dass der Greifer 18 relativ zu der zentralen Einheit 20 axial verschiebbar ist. Ein Mittel, das gleichzeitig als Antrieb und ähnlich wie ein Loslager fungieren kann, ist beispielsweise ein Zylinder, der, wenn er mit Druckluft beaufschlagt ist, einen Antrieb darstellt, und bei dem Drucklosigkeit eine kräftemäßige Entkopplung zwischen der Zentraleinheit 20 und dem Greifer 18 bewirkt. Zusätzlich stellt die Hubbegrenzung des Zylinders in seinen Endlagen einen Anschlag dar, so dass sichergestellt ist, dass der Greifer in Transportrichtung des Lebensmittelriegels nicht zu weit bewegt werden kann und damit mit dem Messer in Kontakt kommt. Die Funktionsweise der erfindungsgemäßen Aufschneidavorrichtung wird in den Figuren 3a bis 3c und 4a bis 4c erläutert. FIG. 2b shows the slicer according to FIG. 2a in a plan view, wherein the conveyor belts 4 have been omitted for clarity. The present exemplary slicing machine is suitable for slicing the four parallel food bars arranged in a plane. Accordingly, the slicer has four grippers 18, which are each brought into contact with a food bar and their claws 7 thereby (not shown) in the food bar are driven. The grippers 18 are arranged on a central unit 20, which is displaceable along a guide 22. The displacement of the central unit 20 can take place either by a motor or by the food bars which are connected to the grippers and which are transported by means of the conveyor belts 4 in the direction of the knife, or by the conveyor belts. The unit 20 may also be fixed in position relative to the guide 22. Each gripper 18 further has a drive 21, with which the gripper is movable or fixable relative to the central unit 20. This drive 21 can be switched to function as or similar to a floating bearing, ie, the gripper 18 is axially displaceable relative to the central unit 20. A means which can simultaneously act as a drive and similar to a floating bearing is, for example, a cylinder which, when pressurized with compressed air, constitutes a drive and, in the absence of pressure, effects a decoupling between the central unit 20 and the gripper 18. In addition, the stroke limit of the cylinder in its end positions is a stop, so that it is ensured that the gripper can not be moved too far in the transport direction of the food bar and thus comes into contact with the knife. The operation of the Aufschneidavorrichtung invention is in the FIGS. 3a to 3c and 4a to 4c explained.

In den Figuren 3a bis 3c ist eine Funktionsweise der erfindungsgemäßen Vorrichtung dargestellt. Figur 3a zeigt den Zustand vor dem Aufschneiden der Lebensmittelriegel 2. Die Lebensmittelriegel 2 werden jeweils manuell oder maschinell in eine Führungstrasse eingelegt und mit einem Anschlag 16, in dem vorliegenden Fall ein Schieber, in Kontakt gebracht, so dass sich die dem Messer 11 (nicht dargestellt) zugewandten Enden auf einer Ebene parallel zu dem Messer befinden. Der Fachmann erkennt, dass dazu nicht notwendigerweise ein Anschlag benötigt wird. Des weiteren erkennt der Fachmann, dass die Lebensmittelriegel unterschiedlich lang sind, was erfahrungsgemäß der Praxis entspricht. Die Lebensmittelriegel 2 werden durch Transportbänder 4 in Richtung des Messers transportiert. Die Transportbänder sind individuell antreibbar, so dass der Vorschub jedes einzelnen Lebensmittelriegels und damit die jeweilige Stärke der abgeschnittenen Scheiben einstellbar ist; d.h. dass die Geschwindigkeit mit der die Lebensmittelriegel jeweils aufgeschnitten werden unterschiedlich sein kann. Die Greifer 18 befinden sich in dem vorliegenden Fall hinter dem hinteren Ende der Lebensmittelriegel 2. Vor oder während des Aufschneidens wird die zentrale Einheit 20, an der die Greifer angeordnet sind, mit einem Motor entlang der Führung 22 in Richtung der hinteren Enden der Lebensmittelriegel bewegt, bis ein Greifer 18 einen Lebensmittelriegel berührt. Die Krallen dieses Greifers werden dann mit diesem Lebensmittelriegel in Eingriff gebracht wird. Die Greifer 18 sind so relativ zu der Zentraleinheit 20 gelagert bzw. angetrieben, dass sie nacheinander oder gleichzeitig mit den jeweiligen Lebensmittelriegeln in Kontakt gebracht und mit diesen Verbunden werden können, ohne dass die Lebensmittelriegel nennenswert komprimiert werden. Diese Verfahrensweise hat insbesondere vor dem Beginn des Aufschneidens den Vorteil, dass die Lebensmittelriegel nicht nennenswert gegen den Anschlag 16 gedrückt werden, so dass der Anschlag entfernt werden kann, ohne die Lebensmittelriegel beschädigt werden. Die Greifer müssen die Lebensmittelriegel auch nicht zurückgehen, wie es beispielsweise in der DE 100 50 713 A1 gelehrt wird, damit der Anschlag überhaupt entfernt werden kann. Ein weiter Vorteil der vorliegenden Erfindung ist, dass die parallel Ausrichtung der vorderen Enden der Lebensmittelriegel auch nach deren Verbund mit den Greifern erhalten bleibt. Diese Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass vor dem Aufschneiden der Lebensmittelriegel nicht notwendigerweise ein sogenannter Trimmschnitt, der Materialverlust bedeutet durchgeführt werden muss, um eine parallel Ausrichtung der Lebensmittelriegel auf einer Linie zu erreichen. Während des Aufschneidens hat diese erfindungsgemäße Verfahrensweise den Vorteil, dass bei der Herstellung des Kontakts zwischen Greifer und Lebensmittefriegel nicht unkontrolliert dicke Lebensmittelscheiben entstehen. Nachdem alle Greifer mit den jeweiligen Lebensmittelriegeln in Kontakt gebracht wurden, können sowohl der Antrieb der Zentraleinheit als auch die Antriebe 21 der jeweiligen Greifer 18 so eingestellt werden, dass sowohl die Zentraleinheit 20 entlang der Führung 22 als auch die Greifer 18 in den Führungen 21 frei verschieblich gelagert sind, so dass die Greifer 18 und damit die Zentraleinheit 20 von den Lebensmitteiriegein 2 in Richtung des Messers gezogen werden. Des weiteren ist es möglich, dass die Zentraleinheit 20 mit einem Motor mit einer mittleren Geschwindigkeit entlang der Führung 22 bewegt wird. In diesem Fall sind die Greifer 18 verschieblich gelagert und können mit einem Geber versehen sein, der ihre jeweilige Position an eine Steuereinheit übermittelt, so dass die Steuereinheit beispielsweise informationen darüber erhält, ob ein lebensmittelriegel schneller als andere aufgeschnitten wird. Weiterhin ist es möglich, dass die Zentraleinheit 20 entlang der Führung 22 frei verschiebbar gelagert ist und die Greifer nicht relativ zu der Zentraleinheit bewegbar sind, so dass sichergestellt ist, dass zumindest nach dem Kontakt mit den Greifern 18 alle Lebensmittelriegel mit derselben Geschwindigkeit aufgeschnitten werden. In jedem Fall weisen die Greiferweisen nach dem Kontakt mit dem Lebensmittelriegel keinen eigenen Antrieb auf und sind deshalb auch nicht in der Lage die Lebensmittelriegel in Richtung des Messers anzutreiben. Die Greifer 18 werden entweder durch den Lebensmittelriegel und/oder bevorzugt durch die Transportbänder 4 in Richtung des Messers bewegt In Figur 3c ist ein Stadium kurz vor Beendigung des Aufschneidens dargestellt. Da die Lebensmittelriegel zum einen ungleich lang sind und zum anderen auch unterschiedlich schnell aufgeschnitten werden können, ist der zweite Lebensmittelriegel von links bis kurz vor die Krallen des Greifers aufgeschnitten. An dieser Stelle muss zumindest das Aufschneiden dieses Lebensmittelriegels beendet werden, dadurch dass dieser Lebensmittelriegel beispielsweise durch seinen Antrieb 21 zurückgezogen wird. Es ist jedoch auch denkbar, dass an dieser Stelle das Aufschneiden aller vier Lebensmittelriegel beendet wird, indem die Zentraleinheit 20 von dem Messer wegbewegt wird und danach oder gleichzeitig die Krallen aus den Lebensmittelriegeln gelöst werden. Die nicht vollständig aufgeschnittenen Lebensmittelriegel können gesammelt und einer Wiederverwertung zugeführt werden. Nachdem das Aufschneiden der Lebensmlttelriegel beendet wird, wird Zentraleinheit 20 und die Krallen 18 relativ zu der Zentraleinheit 20 zu der Ausgangsposition gemäß Figur 3a zurückgefahren und die Führungstrassen können mit neuen Lebensmittelriegeln beladen werden, diese dann aufgeschnitten werden.In the FIGS. 3a to 3c an operation of the device according to the invention is shown. FIG. 3a shows the state before cutting the food bar 2. The food bar 2 are each manually or mechanically inserted in a guide road and with a stop 16, in the In the present case, a slider, brought into contact, so that the knife 11 (not shown) facing ends are located on a plane parallel to the knife. The person skilled in the art recognizes that this does not necessarily require a stop. Furthermore, the person skilled in the art recognizes that the food bars have different lengths, which according to experience corresponds to practice. The food bars 2 are transported by conveyor belts 4 in the direction of the knife. The conveyor belts are individually driven, so that the feed of each food bar and thus the respective strength of the cut slices is adjustable; that is, the speed at which the food bars are cut open may be different. The grippers 18 are in the present case behind the rear end of the food bar 2. Before or during the slicing, the central unit 20 on which the grippers are arranged is moved by a motor along the guide 22 towards the rear ends of the food bars until a gripper 18 touches a food bar. The claws of this gripper are then engaged with this food bar. The grippers 18 are mounted or driven relative to the central unit 20 in such a way that they can be brought into contact and connected to the respective food bars one after the other or simultaneously, without the food bars being appreciably compressed. This procedure has the advantage, in particular before the start of slicing, that the food bars are not pressed appreciably against the stop 16, so that the stop can be removed without damaging the food bars. The grippers do not have to go back the food bars, as for example in the DE 100 50 713 A1 is taught so that the stop can be removed at all. A further advantage of the present invention is that the parallel alignment of the front ends of the food bars is maintained even after their association with the grippers. This embodiment of the present invention has the advantage that prior to slicing the food bars, not necessarily a so-called trim cut, which means loss of material, has to be performed in order to achieve a parallel alignment of the food bars on a line. During slicing, this procedure according to the invention has the advantage that in the production of the contact between the gripper and foodstuff bars, non-controlled, thick food slices are produced. After all the grippers with the Both the drive of the central unit and the drives 21 of the respective gripper 18 can be adjusted so that both the central unit 20 along the guide 22 and the gripper 18 are mounted freely displaceable in the guides 21, so that the gripper 18 and thus the central unit 20 are pulled from the Lebensiitteiriegein 2 in the direction of the knife. Furthermore, it is possible that the central unit 20 is moved along the guide 22 with a motor at a medium speed. In this case, the grippers 18 are slidably mounted and may be provided with a transmitter, which transmits its respective position to a control unit, so that the control unit, for example, receives information about whether a food bar is cut faster than others. Furthermore, it is possible that the central unit 20 is mounted freely displaceable along the guide 22 and the grippers are not movable relative to the central unit, so as to ensure that at least after contact with the grippers 18 all food bars are cut open at the same speed. In any case, the gripper ways do not have their own drive after contact with the food latch and therefore are not able to drive the food bars in the direction of the knife. The grippers 18 are moved either in the direction of the knife by the food bar and / or preferably by the conveyor belts 4 Figure 3c a stage is shown shortly before the end of the slicing. Since the food bars on the one hand are unevenly long and on the other hand can be cut at different speeds, the second food bar is cut from the left to just before the claws of the gripper. At this point, at least the slicing of this food bar must be stopped, characterized in that this food bar is withdrawn, for example by its drive 21. However, it is also conceivable that at this point the cutting of all four food bars is stopped by the central unit 20 is moved away from the knife and then or at the same time the claws are released from the food bars. The incompletely cut food bars can be collected and recycled. After the slicing of the food sticks is finished, the central unit 20 and the claws 18 relative to the central processing unit 20 become the home position according to FIG FIG. 3a moved back and The guideways can be loaded with new food bars, which are then cut open.

In den Figuren 4a bis 4c ist eine andere mögliche Ausführungsform der erfindungsgemäßen Vorrichtung bzw. der erfindungsgemäßen Verfahren dargestellt. Wie aus Figur 4a ersichtlich, sind in dem vorliegenden Fall die Lebensmittelriegel so lang, das ihr hinteres Ende hinter den Greifern und der Lebensmittelriegel zumindest teilweise unterhalb der Greifer liegt. Die Lebensmittelriegel werden auch in dem vorliegenden Fall so angeordnet und durch die Transportbänder fixiert, dass sich ihre vorderen Enden auf einer Ebene parallel zu dem Messer befinden, so dass bei Beginn des Aufschneidens kein Trimmschnitt durchgeführt werden muss. Die Lebensmittelriegel werden so lange aufgeschnitten, bis sich ihr hinteres Ende vor den Greifern 18 befinden, die dann zu einem beliebigen Zeitpunkt, jedoch spätestens dann, wenn ein sicherer Halt der Lebensmittelriegel zwischen den Transportbändern 4 nicht mehr gewährleistet ist, mit den Lebensmitteinegein in Eingriff gebracht werden. Ansonsten gelten die zu den Figuren 3a bis 3c gemachten Ausführungen.In the FIGS. 4a to 4c another possible embodiment of the device according to the invention or the inventive method is shown. How out FIG. 4a As can be seen, in the present case, the food bars are so long that their rear end lies behind the grippers and the food bars at least partially below the grippers. The food bars are also arranged in the present case and fixed by the conveyor belts, that their front ends are on a plane parallel to the knife, so that no trimming cut must be carried out at the beginning of slicing. The food bars are cut open until their rear end are in front of the grippers 18, which then at any time, but at the latest when a secure hold of food bars between the conveyor belts 4 is no longer guaranteed, brought into engagement with the Lebensmitteinegein become. Otherwise, the apply to the FIGS. 3a to 3c made statements.
