Insbesondere bei der Verarbeitung von Fleisch in frischem oder gefrorenem Zustand finden diese Maschinen mannigfaltige Verwendungsmöglichkeiten. Da diese Maschinen in der Regel mit einem schnell laufenden, rotierenden Messer ausgerüstet sind, müssen diese Maschinen mit einer Sicherheitsvorrichtung ausgerüstet sein, um Verletzungen des Bedienpersonals zu vermeiden.Crushers are used in a variety of technical today Areas used. Especially when processing meat in fresh or Frozen condition, these machines are diverse Uses. Because these machines usually come with a quick running, rotating knives, these machines must be equipped with a Safety device must be equipped to prevent injuries to the operating personnel avoid.

In der Regel ist diese Sicherheitsvorrichtung heutzutage eine Haube, die vor den Ausgang des Schneidsatzes geklappt wird, um zu vermeiden, daß das Bedienpersonal in den Schneidsatz hineingreift und sich dabei verletzt. Diese Sicherheitsvorrichtung hat jedoch den Nachteil, daß sie nur einen unzureichenden Schutz darstellt, daß eine optische Begutachtung des Zerkleinerungsprozesses und des zerkleinerten Gutes nur bedingt möglich ist.As a rule, this safety device is a hood that is in front of the Output of the cutting set is folded to avoid that Operators reach into the cutting set and injure themselves. This However, the safety device has the disadvantage that it is inadequate Protection means that an optical assessment of the shredding process and of the shredded material is only possible to a limited extent.

Es stellt sich deshalb die Aufgabe, eine Zerkleinerungsmaschine zur Verfügung zu stellen, die die Nachteile des Standes der Technik nicht aufweist.The task is therefore to provide a shredding machine places that do not have the disadvantages of the prior art.

Diese Dickenüberwachung kann sowohl mechanisch als auch elektronisch erfolgen. Vorzugsweise wird sie jedoch an die Standzeit der Lochscheibe gekoppelt, da eine Lochscheibe jeweils nach einer bestimmten Anzahl von Betriebsstunden nachgeschliffen werden muß und sich dementsprechend die Dicke reduziert. Demnach errechnet die erfindungsgemäße Zerkleinerungsmaschine ab welcher Standzeit der Lochscheibe deren Dicke nicht mehr ausreicht, um eine hinreichende Sicherheit gegen Verletzung des Bedienpersonals darzustellen. In a preferred embodiment of the invention Shredding machine, the thickness of the perforated disc is monitored so that can be prevented that the perforated disc with progressive wear it becomes thin that the operating staff put a finger through the perforated disc can and is injured by the rotating knife. This thickness monitoring can done both mechanically and electronically. However, it is preferably on the service life of the perforated disc coupled, since a perforated disc after each certain number of operating hours must be reground and accordingly the thickness is reduced. Accordingly, the invention calculates Shredding machine from which service life of the perforated disc does not have a thickness is sufficient to provide adequate security against violation of the To represent operating personnel.

In einer weiteren bevorzugten Ausführungsform wird die Sicherheitsvorrichtung in die Verschlußmutter des Schneidsatzes integriert. Eine solche Sicherheitsvorrichtung kann eine Lochscheibe oder z. B. ein Drahtgewebe sein. Da diese Sicherheitsvorrichtung einen vergleichsweise großen Abstand zu dem letzten Messer bzw. der dazugehörigen Lochscheibe aufweist, ist diese Form der Sicherungsvorrichtung besonders effizient.In a further preferred embodiment, the safety device is in the Locking nut of the cutting set integrated. Such a safety device can a perforated disc or z. B. be a wire mesh. This one Safety device a comparatively large distance from the last knife or the associated perforated disc, this form is the Safety device particularly efficient.

Vorzugsweise ist das Mittel, auf dem Daten abgespeichert und abgerufen werden können, ein Sensorchip, der einen ersten abfragbaren Datenspeicher mit Daten aufweist, die als Istwerte zum Abgleich mit den Daten eines zweiten, der Zerkleinerungsmaschine zugeordneten Datenspeichers verwendet werden, dessen auf die Lochscheibe abgestimmte Daten als Sollwerte für einen Ist-Sollwert-Vergleich dienen. Vorzugsweise ist die Steuerung einer Zerkleinerungsmaschine, in die die Lochscheibe eingebaut ist, so ausgelegt, daß diese nicht in Betrieb nehmbar ist, wenn die Istwerte von den Sollwerten abweichen. Auf diese Weise kann die Lochscheibe als Sicherungsvorrichtung dienen, weil durch den Soll-Ist-Vergleich festgestellt werden kann, ob beispielsweise eine Lochscheibe in Flußrichtung hinter dem letzten Messer eingesetzt ist, deren Bohrungsdurchmesser so klein bzw. deren Dicke so groß ist, daß ausgeschlossen werden kann, daß das Bedienpersonal durch das rotierende Messer verletzt wird. Ganz besonders bevorzugt hat die Lochscheibe Löcher, deren Durchmesser ≤ 6 mm beträgt und vorzugsweise eine Dicke ≥ 5 mm.Preferably, the means on which data is stored and called up can, a sensor chip, the first interrogatable data storage with data has as actual values for comparison with the data of a second, the Shredder associated data storage can be used, the Data matched to the perforated disc as target values for an actual target value comparison serve. The control of a comminution machine, into which the Perforated disc is installed, designed so that it cannot be put into operation, if the actual values deviate from the target values. In this way, the Perforated disc serve as a safety device because of the target-actual comparison it can be determined whether, for example, a perforated disk is located behind in the flow direction the last knife is inserted, whose bore diameter is so small or whose Thickness is so large that it can be excluded that the operating personnel the rotating knife is injured. The perforated disc is very particularly preferred Holes whose diameter is ≤ 6 mm and preferably a thickness ≥ 5 mm.

Mit diesen Daten kann automatisch die Abnutzung der Lochscheibe festgestellt werden, so daß, wenn ein bestimmter Abnutzungsgrad der Lochscheibe überschritten ist, die Zerkleinerungsmaschine nicht mehr in Betrieb nehmbar ist, weil die erfindungsgemäße Lochscheibe als Sicherungsvorrichtung nicht mehr ausreichend ist.Further preferably, additional data can be stored on the medium, that affect the running time and the load on the perforated disc. With this data the wear of the perforated disc can be determined automatically, so that when a certain degree of wear of the perforated disc is exceeded, which Shredding machine is no longer operational because the perforated disc according to the invention is no longer sufficient as a safety device is.

Vorzugsweise ist das Mittel, auf dem Daten abgespeichert und abgerufen werden können, in einem abgeschlossenen Hohlraum in der Lochscheibe vorgesehen, so daß er für Unbefugte weder auffindbar ist, noch manipuliert werden kann. Die Anordnung des Mittels sollte in jedem Fall so getroffen werden, daß es, wenn es zufällig entdeckt wird, beim Ausbau unbrauchbar, vorzugsweise zerstört wird.Preferably, the means on which data is stored and called up can, provided in a closed cavity in the perforated disc, so that it can neither be found nor manipulated by unauthorized persons. The Arrangement of the agent should in any case be made so that when it is accidentally discovered, unusable during expansion, preferably destroyed.

Die Datenabfrage aus dem in einer solchen Lochscheibe integrierten Datenspeicher gelingt bei einer Zerkleinerungsmaschine am besten, wenn das Mittel mit einer an der Zerkleinerungsmaschine angeordneten oder mobilen Sende- und Empfangsanlage birektional drahtlos gekoppelt ist, die über einen Verstärker mit dem zweiten Datenspeicher und/oder einer elektronischen Maschinensteuerung verbunden sein kann, so daß der Datenbestand des Mittels abgelesen und geändert werden kann. Die Sende- und Empfangsanlage ist mit besonderem Vorteil in unmittelbarer Nähe der Lochscheibe vorgesehen. The data query from the data memory integrated in such a perforated disc The best way to achieve a shredding machine is to use one the shredder arranged or mobile transmission and Receiving system is bidirectionally wirelessly coupled, via an amplifier with the second data storage and / or an electronic machine control can be connected so that the database of the agent can be read and changed can be. The transmitting and receiving system is particularly advantageous in provided in the immediate vicinity of the perforated disc.

Der in der erfindungsgemäßen Lochscheibe integrierte Datenspeicher liefert nach entsprechender Datenentnahme, Übertragung, Verarbeitung und Wiedergabe auf einem entsprechenden Display die für die Identifizierung der Lochscheibe geeigneten Daten und ggf. auch die Daten eines dazugehörigen Gegenstücks, beispielsweise eines Messers, also des gesamten für die Zerkleinerung verwendeten Systems. In gleicher Weise können die Daten von der Steuerung der Zerkleinerungsmaschine erkannt und insofern beachtet werden, daß der Betrieb der Zerkleinerungsmaschine nur dann zugelassen wird, wenn funktionsgerechte Teile im Einsatz sind.The data memory integrated in the perforated disk according to the invention delivers appropriate data extraction, transmission, processing and playback a suitable display for identifying the perforated disc Data and possibly also the data of an associated counterpart, for example of a knife, i.e. the entire system used for shredding. In Similarly, the data from the controller of the shredder recognized and in so far be noted that the operation of the shredder is only permitted if functional parts are used.

Auch die Überwachung der für die Zerkleinerungsmaschine ordinären Lochscheiben ist nach der Erfindung wesentlich einfacher durchführbar, weil nun aus den von den integrierten Datenspeicher lieferbaren Daten die Seriennummer der Lochscheibe ohne weiteres identifiziert werden kann und deren Abnutzung überwachbar ist, beispielsweise durch die Anzeige von Standzeiten, Schleifintervallen und dergleichen Parametern.Also the monitoring of the perforated disks that are normal for the shredding machine is much easier to carry out according to the invention, because now from the integrated data memory available data the serial number of the perforated disc can be easily identified and their wear can be monitored, for example, by displaying service life, grinding intervals and the like Parameters.

FIG. 1 shows an exploded drawing of the cutting set 14 of the comminution machine 13 according to the invention. Of the shredding machine 13, only a part of the housing 1 can be seen, which receives the cutting set 14. The comminution machine according to the invention has a driven screw with a shaft 2, with which the knives 4, 15 are set in a rotational movement. Furthermore, the cutting set has a pre-cutter 3, two perforated disks 5, 6 and a spacer ring 7. The cutting set 14 is fixed in the housing 1 with the locking nut 8. The person skilled in the art recognizes that the knife 4 cooperates with the perforated disk 5 and the knife 15 with the perforated disk 6. The rough cutter 3, the perforated disks 5, 6 and the spacer ring 7 are rotatably connected to the housing. The rough cutter 3 and the perforated disks 5, 6 each have a sensor chip 10, which is provided in the outer region of the respective component.

Erfindungsgemäß weist die Zerkleinerungsmaschine hinter dem letzten Messer 15 eine Sicherheitsvorrichtung auf, die eine Verletzung des Bedienpersonals durch das Messer 15 verhindert. In dem vorliegenden Beispiel ist diese Sicherheitsvorrichtung die Lochscheibe 6, deren Löcher einen Durchmesser von 6 mm aufweist und die eine Dicke von mehr als 5 mm hat. Die Dicke der Lochscheibe sollte 30 mm nicht überschreiten. Durch diese Gestaltung der Lochscheibe ist es für das Bedienpersonal unmöglich, sich beispielsweise die Finger an dem rotierenden Messer 15 zu verletzen. Der Fachmann erkennt, daß beispielsweise auch eine Lochscheibe in der Verschlußmutter 8 vorgesehen werden kann, die eine besonders gute Sicherheitsvorrichtung darstellt, weil sie einen größeren Abstand zu dem rotierenden Messer 15 aufweist, als beispielsweise die Lochscheibe 6. Eine Lochscheibe als Sicherung in der Verschlußmutter 8 könnte größere Bohrung als 6 mm aufweisen und eine geringere Dicke als 5 mm haben.According to the invention, the comminution machine has behind the last knife 15 a safety device on that an injury to the operator by the Knife 15 prevented. In the present example, this is safety device the perforated disc 6, the holes of which have a diameter of 6 mm and the one Has a thickness of more than 5 mm. The thickness of the perforated disc should not be 30 mm exceed. This design of the perforated disc makes it suitable for Operating personnel impossible, for example, the fingers on the rotating Injuring knife 15. The person skilled in the art will recognize that, for example, a Perforated disk can be provided in the locking nut 8, which is a special one good security device because it is a greater distance from that has rotating knife 15, for example, the perforated disc 6. A Perforated disk as a safety device in the locking nut 8 could have a larger hole than 6 mm and have a thickness less than 5 mm.

Figur 2 zeigt die erfindungsgemäße Zerkleinerungsmaschine mit dem Schneidsatz 14 in eingebautem Zustand. Die Schnecke 2, die an ihrem Ende eine Antriebswelle aufweist, fördert das zu schneidende Material, in dem vorliegenden Fleisch, durch den Vorschneider 3 hindurch zu dem ersten Messer 4. Dieses Messer 4 wirkt mit der Lochscheibe 5 zusammen und zerkleinert das Fleisch. Nachdem das Fleisch durch die Lochscheibe 5 hindurchgedrückt worden ist, wird es durch ein weiteres Messer 15 und eine weitere Lochscheibe 6 noch einmal zerkleinert. Der Fachmann erkennt, daß das Messer 15 und die Lochscheibe 6 zusammenwirken. Die Lochscheibe 6 dient gleichzeitig als Sicherheitsvorrichtung, da ihre Bohrung ≤ 6 mm sind und ihre Dicke mehr als 5 mm beträgt, so daß es für das Bedienpersonal unmöglich ist, einen Finger durch die Lochscheibe zu stecken und sich an dem rotierenden Messer 15 zu verletzen. Die Messer 4 und 15 werden durch die Welle der Schnecke 2 angetrieben, während der Vorschneider 3 und die Lochscheiben 5 und 6 ortsfest mit dem Gehäuse verbunden sind. Der gesamte Schneidsatz wird durch den Distanzring 7 und die Verschlußmutter 8 in dem Gehäuse verspannt. Der Vorschneider 3 und die Lochscheiben 5 und 6 weisen Sensorchips 10 auf, die bidirektional und drahtlos mit der Sende- Empfangsvorrichtung 9 verbunden sind, so daß auf den Sensorchips Daten abgespeichert und abgerufen werden können. In dem vorliegenden Fall werden die Seriennummer und die Standzeit auf dem Sensorchip abgespeichert und in regelmäßigen Abständen automatisch von der erfindungsgemäßen Zerkleinerungsmaschine abgerufen und auf einem Display, das nicht dargestellt ist, angezeigt. Insbesondere falls die Sicherheitsvorrichtung 6 nicht vorhanden ist oder nicht ausreichend dimensioniert ist oder wenn die Standzeit und damit der Verschleiß der Sicherungsvorrichtung 6 zu groß ist, kann die erfindungsgemäße Zerkleinerungsmaschine nicht angefahren werden. Damit kann eine Verletzung des Bedienpersonals nachhaltig verhindert werden. Figure 2 shows the shredding machine according to the invention with the cutting set 14 in the installed state. The worm 2, which has a drive shaft at its end, conveys the material to be cut, in the meat at hand, through the pre-cutter 3 to the first knife 4. This knife 4 interacts with the perforated disc 5 and comminutes the meat. After the meat has been pressed through the perforated disc 5, it is comminuted again by a further knife 15 and a further perforated disc 6. The person skilled in the art recognizes that the knife 15 and the perforated disk 6 interact. The perforated disc 6 also serves as a safety device since its bore is 6 6 mm and its thickness is more than 5 mm, so that it is impossible for the operating personnel to insert a finger through the perforated disc and injure themselves on the rotating knife 15. The knives 4 and 15 are driven by the shaft of the screw 2, while the pre-cutter 3 and the perforated disks 5 and 6 are fixedly connected to the housing. The entire cutting set is clamped in the housing by the spacer ring 7 and the locking nut 8. The roughing cutter 3 and the perforated disks 5 and 6 have sensor chips 10 which are connected bidirectionally and wirelessly to the transceiver 9, so that data can be stored and called up on the sensor chips. In the present case, the serial number and the service life are stored on the sensor chip and automatically called up at regular intervals by the comminution machine according to the invention and shown on a display which is not shown. In particular, if the safety device 6 is not present or is not sufficiently dimensioned or if the service life and thus the wear of the safety device 6 is too great, the comminution machine according to the invention cannot be started up. In this way, injury to the operating personnel can be prevented in the long term.
