Description

Kuttermesser Meatmincer
Die vorliegende Erfindung betrifft ein Kuttermesser, eine Messerkopfscheibe und einen Messerkopf bestehend aus der erfindungsgemäßen Messerkopfscheibe und dem erfindungsgemäßen Messer.The present invention relates to a cutter knife, a cutter head disc and a cutter head consisting of the cutter head disc according to the invention and the knife according to the invention.
Kutter zum Zerkleinern und Mischen von frischen oder gefrorenen Lebensmitteln, beispielsweise Fleisch, weisen einen Messerkopf auf, der aus einer Vielzahl von hintereinander angeordneten Messern besteht, die an sogenannten Messerkopfscheiben befestigt werden. Die Messer müssen an den Messerkopfscheiben in einer ganz bestimmten Konfiguration angeordnet werden, damit ein befriedigendes Schneidergebnis erzielt wird. Des weiteren ist es zur Erzielung eines guten Schneidergebnisses und auch aus Sicherheitsgründen wichtig, dass bestimmte Messer nur mit den dafür vorgesehenen Messerkopfscheiben kombiniert werden, was bei Messern bzw. Messerkopfscheiben gemäß dem Stand der Technik nicht immer gewährleistet war.Cutters for comminuting and mixing fresh or frozen food, such as meat, have a cutter head consisting of a plurality of knives arranged one behind the other, which are fastened to so-called cutter head disks. The knives must be arranged on the cutterhead discs in a specific configuration to achieve a satisfactory cutting result. Furthermore, in order to achieve a good cutting result and also for safety reasons, it is important that certain knives are combined only with the knife blade disks provided for this purpose, which was not always ensured in the case of knives or knife head disks according to the prior art.
Es war deshalb die Aufgabe der vorliegenden Erfindung, ein Kuttermesser zur Verfügung zu stellen, dass die Nachteile des Standes der Technik nicht aufweist.It was therefore the object of the present invention to provide a cutter knife that does not have the disadvantages of the prior art.
Gelöst wird die Aufgabe erfindungsgemäß mit einem Messer gemäß Patentanspruch 1. Bevorzugte Ausführungsformen des erfindungsgemäßen Messers sind in den Unteransprüchen 2 und 3 beansprucht.The object is achieved according to the invention with a knife according to claim 1. Preferred embodiments of the knife according to the invention are claimed in the subclaims 2 and 3.
Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass das erfindungsgemäße Messer nur auf dafür vorgesehenen Messerkopfscheiben eingesetzt werden kann. Die Messer können nicht seitenverkehrt eingesetzt werden, so dass das erfindungsgemäße Messer eine Einbauhilfe für das Bedienpersonal bereithält.It was extremely surprising for the person skilled in the art and it was not to be expected that the knife according to the invention could only be used on knife blade disks intended for this purpose. The knives can not be reversed, so that the knife according to the invention provides an installation aid for the operating personnel.
Erfindungsgemäß weist das Messer mindestens ein Mittel auf, mit dem es an der Messerkopfscheibe anbringbar ist. Des weiteren weist es versetzt zur Mittelachse des Messers eine Ausnehmung auf, die eine in der Messerkopfscheibe angeordnete Ausbuchtung bei der Montage des Messers an der Messerkopfscheibe aufnimmt. Diese Ausnehmung kann jede dem Fachmann geläufige Form und Größe aufweisen. Vorzugsweise handelt es sich jedoch um ein Langloch, dessen Breite im wesentlichen dem Durchmesser eines vorzugsweise zylindrischen Bolzens entspricht, der aus der Messerkopfscheibe in das Langloch hineinragt. In einer ganz besonders bevorzugten Ausführungsform weist das Langloch eine Skalierung auf. Diese Ausführungsform der vorliegenden Erfindung hat den Vorteil, dass anhand des Langloches überprüft werden kann, ob das Messer eine vorher ermittelte Stellung relativ zu der Messerkopfscheibe einnimmt. Des weiteren kann mit der Skalierung ermittelt werden, ob bei korrekt sitzenden Befestigungsmitteln ein Original oder ein bereits einmal abgeschliffenes Messer auf der jeweiligen Messerkopfscheibe eingesetzt werden muss.According to the invention, the knife has at least one means with which it can be attached to the cutter head disk. Furthermore, it has offset to the central axis of the knife on a recess which receives a arranged in the cutterhead disc bulge during assembly of the knife on the cutter head disc. This recess can have any shape and size familiar to the person skilled in the art. Preferably, however, it is a slot whose width substantially corresponds to the diameter of a preferably cylindrical bolt, which protrudes from the cutter head disc in the slot. In a very particularly preferred embodiment, the slot has a scale. This embodiment of the present invention has the advantage that it can be checked on the basis of the elongated hole, whether the knife occupies a previously determined position relative to the cutter head disc. Furthermore, it can be determined with the scaling, whether with correctly seated fasteners an original or a previously abraded knife must be used on the respective cutter head disc.
Ein weiterer Gegenstand der vorliegenden Erfindung ist eine Messerkopfscheibe für einen Fleischkutter, an der mindestens ein Messer anbringbar ist und die einen Bolzen aufweist, der nicht auf ihrer Mittelachse angeordnet ist und der nicht zur Befestigung des Messers an der Messerkopfscheibe dient.Another object of the present invention is a cutter head disc for a meat cutter to which at least one knife is attachable and which has a bolt which is not arranged on its central axis and which does not serve for attachment of the knife to the cutter head disc.
Die erfindungsgemäße Messerkopfscheibe hat den Vorteil, dass an ihr nur Messer anbringbar sind, die eine Ausnehmung aufweisen, deren Form, Größe und Lage kompatibel zu der Ausbuchtung in der Messerkopfscheibe ist. Des weiteren stellt die erfindungsgemäße Messerkopfscheibe eine Einbauhilfe für das Bedienpersonal zur Verfügung, mit der verhinderbar ist, dass die Messer seitenverkehrt an der Messerkopfscheibe angebracht werden.The knife head disc according to the invention has the advantage that only knives are attached to it, which have a recess whose shape, size and position is compatible with the bulge in the cutter head disc. Furthermore, the cutter head disc according to the invention provides an installation aid for the operating personnel with which it can be prevented that the blades are mounted laterally reversed on the cutter head disc.
Vorzugsweise weist die Messerkopfscheibe mindestens eine Ausnehmung auf, in der jeweils mindestens ein Exzenterhaltebolzen anbringbar ist. Mit den Exzenterhaltebolzen wird die Lage des Messers an der Messerkopfscheibe festgelegt. Bezüglich der Exzenterhaltebolzen und der entsprechenden Anbringung des Messers an der Messerkopfscheibe wird auf die parallele Patentanmeldung DE 103 16 303.4 verwiesen, die hiermit als Referenz eingeführt wird und somit als Teil der Offenbarung gilt.Preferably, the cutter head disc has at least one recess, in each of which at least one eccentric retaining bolt can be attached. The eccentric retaining bolts determine the position of the blade on the cutterhead. With regard to the eccentric retaining bolts and the corresponding attachment of the blade to the cutter head disc, reference is made to the co-pending patent application DE 103 16 303.4, which is hereby introduced as a reference and thus applies as part of the disclosure.
Ein weiterer Gegenstand der vorliegenden Erfindung ist eine Messerkopfscheibe für einen Fleischkutter, an der mindestens ein Messer anbringbar ist, die einen vorzugsweise metallischen Kern zur Aufnahme der Antriebswelle aufweist, wobei der Kern mit einer Ummantelung, vorzugsweise einer Kunststoffummmantelung umschlossen umfasst ist und die Ummantelung auf den Kern geschrumpft ist. Diese Messerkopfscheibe zeichnet sich durch einen sehr guten Verbund zwischen der Ummantelung und dem Kern, der auch den großen Kräften, die bei den hohen Drehzahlen auftreten Stand hält.Another object of the present invention is a cutter head disc for a meat cutter to which at least one knife is attachable, the one preferably comprises a metallic core for receiving the drive shaft, wherein the core is enclosed with a sheath, preferably a plastic sheath encloses and the sheath has shrunk onto the core. This knife head disc is characterized by a very good bond between the sheath and the core, which also withstands the great forces that occur at high speeds.
Ein weiterer Gegenstand der vorliegenden Erfindung ist ein Messerkopf bestehend aus der erfindungsgemäßen Messerkopfscheibe und mindestens einem erfindungsgemäßen Messer, bei dem die Exzenterhaltebolzen der Messerkopfscheibe in die Bohrungen der Messer eingeführt werden und die in der Messerkopfscheibe erfindungsgemäß vorhandenen Ausbuchtungen in die in den Messern vorhandenen Ausnehmungen hineinragen.A further subject of the present invention is a knife head consisting of the knife head disc according to the invention and at least one knife according to the invention, in which the eccentric retaining bolts of the knife head disc are inserted into the holes of the knives and the protrusions present in the knife head disc project into the recesses provided in the knives.
Es war für den Fachmann überaus erstaunlich und nicht zu erwarten dass mit dem erfindungsgemäßen Messerkopf eine falsche Kombination von Messern und Messerkopfscheiben ausgeschlossen werden kann . Des weiteren wird mit dem erfindungsgemäßen Messerkopf verhindert, dass die Messer seitenverkehrt auf den Messerkopfscheiben angeordnet werden. Anhand der Skalierung der Langlöcher in den Messern kann die Lage der Messer relativ zu den Messerkopfscheiben überprüft werden.It was extremely surprising for the person skilled in the art and not to be expected that with the cutter head according to the invention an incorrect combination of knives and cutter head disks can be ruled out. Furthermore, it is prevented with the cutter head according to the invention that the blades are arranged laterally reversed on the cutter head disks. Based on the scaling of the slots in the knives, the position of the knives relative to the cutter head discs can be checked.
Ein weiterer Gegenstand der vorliegenden Erfindung ist eine Vorrichtung mit einem Mittel zum Befestigen eines erfindungsgemäßen Messers, beispielsweise einem Drehtisch, und einem davon beabstandeten Mittel, mit dem die richtige Stellung der Exzenterbolzen ermittelbar ist.Another object of the present invention is a device having a means for attaching a knife according to the invention, for example a turntable, and a spaced therefrom means with which the correct position of the eccentric pin can be determined.
Mit der erfindungsgemäßen Vorrichtung kann die korrekte Stellung der Exzenterbolzen ermittelt werden.With the device according to the invention, the correct position of the eccentric pin can be determined.
Im Folgenden wird die Erfindung anhand der Figuren 1 bis 4 erläutert. Diese Erläuterungen sind lediglich beispielhaft, schränken den allgemeinen Erfindungsgedanken nicht ein und gelten gleichermaßen für das erfindungsgemäße Messer, die erfindungsgemäße Messerkopfscheibe, den erfindungsgemäßen Messerkopf sowie die erfindungsgemäße Kontrollvorrichtung.The invention is explained below with reference to FIGS. 1 to 4. These explanations are merely exemplary, do not limit the general idea of the invention and apply equally to the invention Knife, the knife head disc according to the invention, the cutter head according to the invention and the control device according to the invention.

Figur 2 zeigt zwei Originalmesser, die an einer Messerkopfscheibe angeordnet sindFIG. 2 shows two original blades arranged on a blade head disk
Figur 3 zeigt die Kombination aus Messern und Messerkopfscheibe gemäß Figur 2, wobei es sich in dem vorliegenden Fall jedoch um an deren Spitze gekürzte Messer handeltFIG. 3 shows the combination of knives and cutter head disc according to FIG. 2, but in the present case it is knives shortened at the tip thereof
Figur 4 zeigt die erfindungsgemäße KontrollvorrichtungFIG. 4 shows the control device according to the invention
In Figur 1 ist das erfindungsgemäße Messer 8 dargestellt, das sich gemäß dem mit Bezugszeichen 9 dargestellten Pfeil in einem Kutter (nicht dargestellt) dreht. Dementsprechend weist das Messer an seinem unteren Radius eine Schneide 10 auf. Mit den beiden Bohrungen 4 wird das Messer an der Messerkopfscheibe angebracht. Erfindungsgemäß weist das Messer ein Langloch 5 auf, das versetzt zur Mittelachse 3 des Messers 8 angeordnet ist. Dieses Langloch weist eine Skalierung 6 auf, mit der die Position des Messers relativ zu der Meserkopfscheibe erkennbar ist, was in den Figuren 2 und 3 noch näher erläutert wird.In Figure 1, the knife 8 according to the invention is shown, which rotates according to the arrow shown with reference numeral 9 in a cutter (not shown). Accordingly, the knife has a cutting edge 10 at its lower radius. With the two holes 4, the knife is attached to the cutter head disc. According to the invention, the knife has a slot 5, which is arranged offset to the central axis 3 of the knife 8. This elongated hole has a scaling 6, with which the position of the knife relative to the cutter head disc can be seen, which will be explained in more detail in Figures 2 and 3.
Figur 2 zeigt zwei Messer 8, die an einer Messerkopfscheibe 1 angeordnet sind. Die Messerkopfscheibe 1 weist vier Ausnehmungen auf, die jeweils einen Exzenterhaltebolzen 4 aufnehmen, mit dem die Messer 8 an der Messerkopfscheibe 1 angebracht werden. Die Exzenterhaltebolzen 4 haben einen kreisrunden, scheibenförmigen Kopf 4', der an seinem Fuß 4" exzentrisch angeordnet ist, wobei die schwarz gezeichneten Flächen weiter aus der Mitte herausstehen als die weiß gezeichneten Flächen. Diese Exzentrizität erlaubt es, das Messer mit den Bolzen in zwei unterschiedlichen Lagen an der Messerkopfscheibe anzuordnen. Eine Messerkopfscheibe wird als Set mit mehreren Exzenterhaltebolzen geliefert, die sich jedoch nur in dem Grad ihrer Exzentrizität unterscheiden. Der Kopf 4' und der Fuß 4" sind jeweils identisch. Des weiteren ist in der Messerkopfscheibe ein Bolzen 7 angeordnet, der in die Ausnehmung 5 hineinragt. Der Bolzen ist auf keiner der Symmetrieachsen der Messkopfscheibe sowie versetzt zur Mittelachse 3 des Messers angeordnet, so dass die Messer nicht spiegelverkehrt an der Messerkopfscheibe angebracht werden können, was zur Folge hätte, dass die Schneide 10 des Messers nicht in Drehrichtung der Messerkopfscheibe angeordnet wäre. Des weiteren verhindert der Bolzen, dass Messer, die keine entsprechende Bohrung aufweisen auf der Messerkopfscheibe montiert werden können. Wie aus dem vergrößerten Kreisabschnitt erkennbar, weist die Ausnehmung 5 eine Skalierung auf, die dem jeweiligen Exzenterhaltebolzen entspricht. Die obere Skalierung ist für einen Exzenterhaltebolzen gewählt, bei dem das Messer in einer 0- Stellung oder 6 mm nach außen verschoben auf der Messerkopfscheibe angeordnet werden kann. Entsprechend ist die untere Skalierung für einen Exzenterhaltebolzen vorgesehen, bei dem das Messer in der O-Stellung oder 3 mm nach außen versetzt angeordnet sein kann. In dem vorliegenden Fall handelt es sich um Messer, die noch nie in ihrer Länge begrenzt wurden. Dementsprechend korrespondiert der Strich auf dem Bolzen mit der Skalierung 0. Die Messerkopfscheibe besteht aus einem metallischen Kern 16, der mit einem Kunststoffring 17 ummantelt ist. In dem vorliegenden Fall ist der Kunststoffring auf den metallischen Kern geschrumpft. Dafür wird der Kern 16 abgekühlt und/oder der Kunststoffring erwärmt.FIG. 2 shows two knives 8 which are arranged on a cutter head disk 1. The knife head disk 1 has four recesses, each of which receives an eccentric retaining pin 4, with which the knives 8 are attached to the knife head disk 1. The eccentric retaining bolts 4 have a circular disk-shaped head 4 'which is eccentrically arranged on its base 4 ", the black-drawn surfaces projecting further out of the center than the white-painted surfaces, this eccentricity allowing the knife with the bolts in two A knife head disc is supplied as a set with a plurality of eccentric retaining bolts, but differing only in the degree of eccentricity thereof. The head 4 'and the foot 4 "are each identical. Furthermore, a bolt 7 is arranged in the cutter head disk, which protrudes into the recess 5. The bolt is not on any of the Symmetryeaches the Meßkopfscheibe and offset from the central axis 3 of the knife arranged so that the knife can not be mounted mirror-inverted on the cutter head disc, with the result that the blade 10 of the knife would not be arranged in the direction of rotation of the cutter head disc. Furthermore, the bolt prevents that knives that have no corresponding hole can be mounted on the cutterhead disc. As can be seen from the enlarged circle section, the recess 5 has a scale which corresponds to the respective eccentric retaining bolt. The upper scale is selected for an eccentric retaining bolt, where the blade can be placed in a 0 position or 6 mm outwards on the cutterhead disk. Accordingly, the lower scale is provided for an eccentric retaining bolt, in which the blade can be arranged in the O position or 3 mm outwardly offset. In the present case, these are knives that have never been limited in length. Accordingly, the line on the bolt corresponds to the scale 0. The cutter head disk consists of a metallic core 16, which is encased with a plastic ring 17. In the present case, the plastic ring shrunk onto the metallic core. For this, the core 16 is cooled and / or the plastic ring is heated.
Figur 3 zeigt die Messerkopfscheiben/Messer-Anordnung gemäß Figur 2, wobei die Messerspitzen in dem vorliegenden Fall um 6 mm gekürzt wurden. Dementsprechend wurden die Exzenterbolzen von ihrer O-Stellung in die 6 mm- Stellung gedreht, um zu gewährleisten, dass der Abstand zwischen Messerspitze und Kutterschüssel konstant bleibt. Diese Drehung der Exzenterscheibe kann auch anhand der Skalierung erkannt werden, weil sich der Strich auf dem Bolzen 7 nicht mehr in der 0-, sondern in der 6 mm-Stellung befindet. Der Fachmann erkennt, dass die Skalierung zum einen erlaubt zu überprüfen, ob das Messer auf dem richtigen Bolzen sitzt und ob bei korrekt sitzenden Bolzen ein gekürztes oder ein Messer in Originallänge aufgesetzt werden muss.FIG. 3 shows the knife head disk / knife arrangement according to FIG. 2, the knife tips being shortened by 6 mm in the present case. Accordingly, the eccentric pins were rotated from their O position to the 6 mm position to ensure that the distance between the blade tip and cutter bowl remains constant. This rotation of the eccentric disc can also be detected on the basis of the scale, because the stroke on the bolt 7 is no longer in the 0 but in the 6 mm position. Those skilled in the art will recognize that the scaling on the one hand allows to check whether the knife is seated on the correct bolt and whether with correctly seated bolts a shortened or a knife in original length must be placed.
Figur 4 zeigt die erfindungsgemäße Vorrichtung zum Kontrollieren der Messerlänge nach dem Schleifen. Dafür wird das Messer 8 auf einen Drehtisch 13 aufgelegt und mittels eines Bolzens 11, der wiederum in die Ausnehmung 5 hineinragt, an der Vorrichtung befestigt. Beabstandet von dem Drehtisch 13 weist die erfindungsgemäße Vorrichtung eine Schablone auf, mit der die Länge des Messers überprüft werden kann. Die Schablone 12 kann um die Schraube 14 in und gegen den Uhrzeigersinn um jeweils 90° gedreht und in der entsprechenden Lage fixiert werden. Je nach Größe des Kutters kann die Schablone 12 nebst ihrer Fixierung auch noch in der durch den Doppelpfeil 15 dargestellten Richtung verschoben werden. In der oberen Darstellung ist ein Originalmesser, dessen Spitze noch nicht eingekürzt worden ist, auf der Vorrichtung eingespannt. Dementsprechend befindet sich die Schablone in O-Stellung, die auch der Anordnung gemäß Figur 2 entspricht. Die untere Darstellung verdeutlicht die Situation, nachdem das Messer eingekürzt worden ist.
