Description

Die vorliegende Erfindung betrifft einen Wolf mit einer Förderschnecke und einem Schneidsatz, der aus einem der Förderschnecke nachgeordneten ersten Vorschneider, einem weiteren dem ersten Vorschneider nachgeordneten zweiten Vorschneider, einer dem zweiten Vorschneider in festem Abstand nachgeordneten Lochscheibe und einem angetriebenen Messer besteht, welches zwischen dem zweiten Vorschneider und der Lochscheibe angeordnet ist, wobei der Schneidsatz mittels einer Verschlußmutter im Schneckengehäuse fest eingespannt ist.The present invention relates to a wolf with a screw conveyor and a cutting set, which consists of a screw conveyor downstream of the first pre-cutter, a further the first pre-cutter second pre-cutter, the second pre-cutter at a fixed distance downstream perforated disk and a driven knife, which between the second Pre-cutter and the perforated disc is arranged, wherein the cutting set is firmly clamped by means of a lock nut in the screw housing.

Derartige Wölfe für die Zerkleinerung von Fleisch sind aus dem Stand der Technik (DE 298 09 485 U1) bekannt. Bei diesen Wölfen ist insbesondere wichtig, daß das Spiel zwischen dem Messer und der Lochscheibe auf der einen Seite und zwischen dem Messer und dem zweiten Vorschneider auf der anderen Seite möglichst gering ist, damit ein optimales Schneidergebnis erzielt wird. In der Vergangenheit haben sich diese Abstände durch die Abnutzung des Messers während des Schneidvorganges ständig vergrößert, so daß das Schneidergebnis mit der Zeit immer schlechter wurde. Außerdem müssen bei Wölfen gemäß dem Stand der Technik die Schneidsätze ausgetauscht werden, je nachdem, ob Frischfleisch oder Gefrierfleisch verarbeitet werden soll.Such wolves for the cutting of meat are known from the prior art (DE 298 09 485 U1). In these wolves, it is particularly important that the play between the knife and the perforated disc on one side and between the knife and the second precutter on the other side is as small as possible, so that an optimum cutting result is achieved. In the past, these distances have been constantly increased by the wear of the knife during the cutting process, so that the cutting result with time became worse and worse. In addition, in prior art wolves, the cutting sets must be changed depending on whether fresh meat or frozen meat is to be processed.

Es stellt sich deshalb die Aufgabe, einen Wolf zur Verfügung zu stellen, bei dem diese Nachteile des Standes der Technik nicht auftreten.It is therefore the object to provide a wolf available in which these disadvantages of the prior art do not occur.

Die Aufgabe wird durch einen Wolf gemäß Anspruch 1 gelöst.The object is achieved by a wolf according to claim 1.

Erfindungsgemäß wird das Messer von einem Druckelement federnd gegen die Lochscheibe gedrückt. Weiterhin wird der zweite Vorschneider durch ein weiteres Druckelement federnd gegen das Messer gedrückt.According to the invention the knife is pressed by a pressure element resiliently against the perforated disc. Furthermore, the second pre-cutter is pressed by a further pressure element resiliently against the knife.

Vorzugsweise sind die Druckelemente Schraubenfedern und der Anpreßdruck, der auf das jeweilige Bauelement ausgeübt wird, ist vorzugsweise jeweils unterschiedlich. Vorzugsweise ist der Anpreßruck, mit dem das Messer gegen die Lochscheibe gedrückt wird, größer als der Anpreßdruck, mit dem der zweite Vorschneider gegen das Messer gedrückt wird.Preferably, the pressure elements are coil springs and the contact pressure exerted on the respective component is preferably different in each case. Preferably, the contact pressure with which the knife is pressed against the perforated disc, greater than the contact pressure with which the second pre-cutter is pressed against the knife.

Ebenfalls Gegenstand der vorliegenden Erfindung ist ein Wolf gemäß Anspruch 3.Likewise subject of the present invention is a wolf according to claim 3.

Vorzugsweise ist das Druckelement eine Schraubenfeder.Preferably, the pressure element is a helical spring.

Vorteilhafte Ausführungsformen des erfindungsgemäßen Wolfes sind in den Unteransprüchen beschrieben.Advantageous embodiments of the invention Wolf are described in the subclaims.

Durch den erfindungsgemäßen Wolf ist gewährleistet, daß selbst bei fortschreitendem Verschleiß der Abstand zwischen Lochscheibe und Messer sowie zwischen Messer und zweitem Vorschneider konstant bleibt. Ferner ist es möglich, sowohl Frisch- als auch Gefrierfleisch ohne Umrüsten mit dem gleichen Schneidsatz zu verarbeiten, weil durch den gleichbleibenden, voreingestellten Schnittdruck die Schneidwerkzeuge exakt geführt werden. Der Schnittdruck ergibt sich aufgrund der Kennlinie der Druckelemente und den Eigenschaften des zu verarbeitenden Produktes. Desweiteren entfällt ein erhöhter Verschleiß des Schneidsatzes durch übermäßiges Spannen des Schneidsatzes durch die Verschlußmutter.The wolf invention ensures that even with progressive wear, the distance between the perforated disc and knife and between the knife and the second pre-cutter remains constant. Furthermore, it is possible to process both fresh and frozen meat without retooling with the same cutting set, because the cutting tools are exactly guided by the constant, preset cutting pressure. The cutting pressure is due to the Characteristic of the printing elements and the properties of the product to be processed. Furthermore, eliminates increased wear of the cutting set by excessive tensioning of the cutting set by the lock nut.

Der erfindungsgemäße Wolf eignet sich insbesondere zum Zerkleinern von frischem und/oder gefrorenem Fleisch.The wolf invention is particularly suitable for crushing fresh and / or frozen meat.

Figur 1 zeigt eine Zusammenstellungszeichnung des erfindungsgemäßen Wolfes. Der Wolf weist eine teilweise dargestellte Förderschnecke 9 auf, mit der das unzerkleinerte Fleisch zu dem Schneidsatz des Wolfes transportiert wird. Der Schneidsatz besteht aus einem ersten Vorschneider 3, einem zweiten Vorschneider 4, einem Messer 6 und einer Lochscheibe 7. Der erste Vorschneider 3 ist direkt der Förderschnecke 9 nachgeordnet. Dem ersten Vorschneider 3 ist in festem Abstand die Lochscheibe 7 nachgeordnet. Der feste Abstand zwischen dem ersten Vorschneider 3 und der Lochscheibe 7 wird in dem vorliegenden Beispiel durch den Abstandhalter 5 verwirklicht. Zwischen dem ersten Vorschneider 3 und der Lochscheibe 7 sind der zweite Vorschneider 4 und das Messer 6 angeordnet. Der zweite Vorschneider 4 ist im Gehäuse verschieblich gelagert. In dem vorliegenden Fall stellt der Abstandhalter 5 gleichzeitig die Führung für den zweiten Vorschneider 4 dar. Das Messer 6 ist dem zweiten Vorschneider 4 nachgeordnet. Der Abstand zwischen dem ersten Vorschneider 3 und der Lochscheibe 7 ist größer oder gleich der axialen Erstreckung des Messers 6 und des zweiten Vorschneiders 4. Das Messer 6 ist auf der Antriebswelle 11 verschieblich, jedoch drehfest auf dieser gelagert. Der Schneidsatz wird durch die Verschlußmutter 10 über das Stützkreuz 8 in dem Schneckengehäuse des Wolfes verspannt. Der Abstand zwischen der Lochscheibe 7 und dem ersten Vorschneider 3 ist unabhängig von dem Grad, mit dem die Verschlußmutter 10 angezogen wird. FIG. 1 shows an assembly drawing of the wolf according to the invention. The wolf has a partially shown screw conveyor 9, with the Uncultivated meat is transported to the cutting set of the wolf. The cutting set consists of a first pre-cutter 3, a second pre-cutter 4, a knife 6 and a perforated disc 7. The first pre-cutter 3 is directly downstream of the screw conveyor 9. The first pre-cutter 3, the perforated plate 7 is arranged at a fixed distance downstream. The fixed distance between the first pre-cutter 3 and the perforated disk 7 is realized by the spacer 5 in the present example. Between the first pre-cutter 3 and the perforated disk 7, the second pre-cutter 4 and the knife 6 are arranged. The second pre-cutter 4 is slidably mounted in the housing. In the present case, the spacer 5 simultaneously represents the guide for the second pre-cutter 4. The knife 6 is arranged downstream of the second pre-cutter 4. The distance between the first precut 3 and the perforated disc 7 is greater than or equal to the axial extent of the knife 6 and the second precut 4. The knife 6 is slidably mounted on the drive shaft 11, but rotatably mounted on this. The cutting set is clamped by the locking nut 10 via the support cross 8 in the worm housing of the wolf. The distance between the perforated disc 7 and the first precut 3 is independent of the degree to which the closure nut 10 is tightened.

Der Innendurchmesser des zweiten Vorschneiders 4 ist größer als der Durchmesser der Antriebswelle 11, so daß sich ein erster Ringspalt 12 zwischen dem Vorschneider 4 und der Antriebswelle 11 ergibt. Der Innendurchmesser des ersten Vorschneiders 3 ist teilweise größer als der Innendurchmesser des Vorschneiders 4, so daß ein zweiter Ringspalt 13 zwischen dem ersten Vorschneider 3 und der Antriebswelle 11 entsteht. In diese Ringspalte 12, 13 sind die Schraubenfedern 1 und 2 angeordnet, wobei Schraubenfeder 1 zwischen Messer 6 und Förderschnecke 9 und die Schraubenfeder 2 zwischen dem ersten Vorschneider 3 und dem zweiten Vorschneider 4 wirkt. Diese Anordnung hat den Vorteil, daß sich die Schraubenfedern nicht im unmittelbaren Produktstrom befinden. Dadurch, daß der Wolf zwei Federn aufweist, kann der Anpreßdruck, mit dem das Messer 6 an die Lochscheibe 7 gedrückt wird und der Anpreßdruck mit dem der Vorschneider 4 gegen das Messer 6 gedrückt wird, jeweils unterschiedlich eingestellt werden. Zweckmäßigerweise ist der Anpreßdruck, mit dem das Messer 6 an die Lochscheibe 7 gedrückt wird, größer als der Anpreßdruck, mit dem der Vorschneider 4 an das Messer 6 gedrückt wird. Bei zunehmendem Verschleiß werden das Messer 6 und der Vorschneider 4 immer automatisch nachgestellt, so daß das Schneidergebnis über einen langen Zeitraum konstant bleibt.The inner diameter of the second pre-cutter 4 is greater than the diameter of the drive shaft 11, so that a first annular gap 12 between the pre-cutter 4 and the drive shaft 11 results. The inner diameter of the first pre-cutter 3 is partially larger than the inner diameter of the pre-cutter 4, so that a second annular gap 13 between the first pre-cutter 3 and the drive shaft 11 is formed. In this annular gaps 12, 13, the coil springs 1 and 2 are arranged, wherein coil spring 1 between the knife 6 and screw conveyor 9 and the coil spring 2 between the first precut 3 and the second precut 4 acts. This arrangement has the advantage that the coil springs are not in the immediate product flow. Characterized in that the wolf has two springs, the contact pressure with which the knife 6 is pressed against the perforated disc 7 and the contact pressure with which the pre-cutter 4 is pressed against the blade 6, each set differently. Conveniently, the contact pressure with which the knife 6 is pressed against the perforated disc 7, greater than the contact pressure with which the precutter 4 to the Knife 6 is pressed. With increasing wear, the knife 6 and the precutter 4 are always readjusted automatically, so that the cutting result remains constant over a long period of time.

In Figur 2 ist eine Ausführungsform des Abstandhalters 5 dargestellt, die jedoch nicht in dem Wolf gemäß Figur 1 eingebaut ist. Der Abstandshalter 5 ist zwischen dem ersten Vorschneider 3 und der Lochscheibe 7 angeordnet. Der Abstandhalter 5 besteht aus einem Ring 15 und sechs Stegen 16. Der Ring 15 wird in einer Aussparung des ersten Vorschneiders 3 gelagert, während sich die Lochscheibe 7 an den Stegen 16 abstützt. Die Stege 16 dienen außerdem als Führung für die axiale Verschiebung des zweiten Vorschneiders 4. FIG. 2 shows an embodiment of the spacer 5 which, however, is not installed in the wolf according to FIG. The spacer 5 is arranged between the first precut 3 and the perforated disc 7. The spacer 5 consists of a ring 15 and six webs 16. The ring 15 is mounted in a recess of the first pre-cutter 3, while the perforated disc 7 is supported on the webs 16. The webs 16 also serve as a guide for the axial displacement of the second pre-cutter. 4

Figur 3 zeigt den Vorschneider 4. Die Bohrung 17 nimmt die Antriebswelle 11 auf. Durch die sechs Bohrungen 18 wird das Fleisch gedrückt und dabei vorgeschnitten. Am Umfang weist der Vorschneider 4 sechs Einkerbungen 19 auf, die die Stege 16 des Abstandhalters 5 aufnehmen. FIG. 3 shows the pre-cutter 4. The bore 17 receives the drive shaft 11. Through the six holes 18, the meat is pressed while precut. At the periphery of the pre-cutter 4 has six notches 19 which receive the webs 16 of the spacer 5.

Figur 4 zeigt den ersten Vorschneider 3. Durch die Bohrungen 20 wird das Fleisch gedrückt und dabei vorgeschnitten. Die Bohrungen 20 haben denselben Durchmesser wie die Bohrungen 18 und sind fluchtend mit diesen angeordnet. Am Umfang weist der Vorschneider 3 eine Aussparung 21 auf, die den Abstandhalter 5 aufnimmt. Der Kreisring 22 dient als Widerlager für die Schraubenfeder 2. Figure 4 shows the first pre-cutter 3. Through the holes 20, the meat is pressed while pre-cut. The holes 20 have the same diameter as the holes 18 and are arranged in alignment therewith. At the periphery, the pre-cutter 3 has a recess 21 which receives the spacer 5. The circular ring 22 serves as an abutment for the coil spring. 2

In Figur 5 ist eine weitere Ausführungsform des erfindungsgemäßen Wolfes dargestellt, die sich von der Ausführungsform des Wolfes gemäß Figur 1 dahingehend unterscheidet, daß er nur eine Schraubenfeder 2 als Druckelement aufweist. Diese Schraubenfeder 2 drückt den Vorschneider 4 gegen das Messer 6. Dieses Messer 6 wiederum wird durch den Druck der Schraubenfeder gegen die Lochscheibe 7 gepreßt. Durch diese Ausführungsform wird gewährleistet, daß selbst bei Verschleiß des Scheidsatzes der Abstand zwischen dem Messer und der Lochscheibe einerseits und zwischen dem Messer und dem Vorschneider 4 andererseits konstant bleibt. Diese Ausführungsform des erfindungsgemäßen Wolfes ist besonders einfach herzustellen, zusammenzusetzen und zu warten. FIG. 5 shows a further embodiment of the wolf according to the invention, which differs from the embodiment of the wolf according to FIG. 1 in that it has only one helical spring 2 as a pressure element. This coil spring 2 presses the pre-cutter 4 against the knife 6. This knife 6 in turn is pressed by the pressure of the coil spring against the perforated disc 7. This embodiment ensures that even when the Scheidsatzes wear the distance between the blade and the perforated disc on the one hand and between the knife and the precutter 4 on the other hand remains constant. This embodiment of the wolf according to the invention is particularly easy to manufacture, assemble and maintain.

Figur 6 zeigt eine weitere Ausführungsform des ersten Vorschneiders 3. Im Unterschied zu dem ersten Vorschneider 3 gemäß Figur 4, weist dieser Vorschneider 3 Bohrungen 24 auf. Diese Bohrungen 24 nehmen Bolzen 25 auf (vgl. Figur 8), die an dem zweiten Vorschneider 4 befestigt sind. Die Bohrungen 24 dienen den Bolzen 25 als axiale Führung. FIG. 6 shows a further embodiment of the first pre-cutter 3. In contrast to the first pre-cutter 3 according to FIG. 4, this pre-cutter 3 has bores 24. These holes 24 receive bolts 25 (see Figure 8), which are attached to the second precut 4. The holes 24 serve the bolt 25 as an axial guide.

Figur 7 zeigt eine weitere Ausführungsform des Vorschneiders 4, der Bohrungen 23 aufweist. Diese Bohrungen haben in der Mitte ein Gewinde, in das die Bolzen 25 eingeschraubt werden können. Der Fachmann erkennt, daß die Bolzen 25 von zwei Seiten in das Gewinde der Bohrung 23 geschraubt werden können. FIG. 7 shows a further embodiment of the rough cutter 4, which has bores 23. These holes have a thread in the middle, in which the bolts 25 can be screwed. The skilled artisan will appreciate that the bolts 25 can be screwed from two sides into the thread of the bore 23.

Figur 8 zeigt eine Zusammenstellungszeichnung des erfindungsgemäßen Wolfes, der im wesentlichen dem Wolf gemäß Figur 1 entspricht. Bei dem Wolf gemäß Figur 4 sind Bolzen 25 in die Bohrungen 23 des zweiten Vorschneiders 4 geschraubt. Diese Bolzen 25 werden von Bohrungen 24 in dem ersten Vorschneider 3 aufgenommen. Die Bohrungen 24 sind im Durchmesser so dimensioniert, daß die Bolzen 25 nur ein geringes Spiel in den Bohrungen 24 haben und die Bohrungen 24 somit als axiales Lager für die Bolzen 25 und damit für den zweiten Vorschneider 4 dienen. FIG. 8 shows an assembly drawing of the wolf according to the invention, which essentially corresponds to the wolf according to FIG . In the wolf according to Figure 4 bolts 25 are screwed into the holes 23 of the second precut 4. These bolts 25 are received by bores 24 in the first precut 3. The holes 24 are dimensioned in diameter so that the bolts 25 have only a small clearance in the holes 24 and the holes 24 thus serve as an axial bearing for the bolts 25 and thus for the second precut 4.

Figur 9 zeigt eine weitere Ausführungsform des Abstandhalters 5. Dieser Abstandhalter entspricht den Abstandhaltern in den Figuren 1, 5, 8. Der Abstandhalter 5 weist eine Öffnung auf, durch die Knorpel und dergleichen aus der Fleischmasse abgeschieden werden können. Der Abstandhalter kann aus Kunststoff oder Stahl gefertigt sein. FIG. 9 shows a further embodiment of the spacer 5. This spacer corresponds to the spacers in FIGS. 1, 5, 8. The spacer 5 has an opening through which cartilage and the like can be separated from the meat mass. The spacer can be made of plastic or steel.
