Description

Die vorliegende Erfindung bezieht sich auf eine Zerkleinerungsvorrichtung, insbesondere für Lebensmittel, mit mindestens zwei in Durchlaufrichtung des Zerkleinerungsgutes hintereinanderliegenden Lochplatten und darauf rotierenden Messern, deren Messerköpfe in und gegen die Durchlaufrichtung des Zerkleinerungsgutes gegenüber den Lochplatten verstellbar sind. Bei bekannten Vorrichtungen dieser Art sind die Messerköpfe fest auf der Antriebswelle angeordnet und ihre Verstellung erfolgt gemeinsam durch eine axiale Verschiebung der Messerwelle. Sofern Lochplatten von gleicher Stärke verwendet werden und auch sichergestellt ist, daß der Abschliff der Lochplatten und Messer gleich bleibt, kann die Einstellung des richtigen Abstandes zwischen Messern und Lochplatte problemlos vorgenommen werden. Wenn dagegen Lochscheiben und Messerköpfe bzw. Messer mit verschiedenen Stärken verwendet werden, kann nur immer an einer Lochplatte eine optimale Einstellung erfolgen. Die Aufgabe der vorliegenden Erfindung ist es daher, auch in derartigen Fällen zwischen allen Lochplatten und Messern den optimalen Abstand einstellen zu können.The present invention relates to a comminution device, especially for food, with at least two lying one behind the other in the direction of flow of the comminution material Perforated plates and knives rotating on them, their knife heads in and against the direction of the comminution are adjustable compared to the perforated plates. At acquaintances Devices of this type have the cutter heads firmly on the drive shaft arranged and their adjustment takes place together by an axial displacement of the knife shaft. Unless perforated plates of the same strength are used and also ensured is that the sanding of the perforated plates and knives is the same remains, setting the correct distance between Knives and perforated plate can be made easily. If against Perforated disks and knife heads or knives with different Starches can only be used on a perforated plate an optimal setting. The task of the present It is therefore an invention, even in such cases between set the optimal distance for all perforated plates and knives to be able to.

Dies wird erfindungsgemäß bei einer oben beschriebenen Zerkleinerungsvorrichtung dadurch erreicht, daß wenigstens eine Lochplatte gegenüber dem auf ihr rotierenden Messer zusätzlich verstellbar ist. Bei einer so ausgebildeten Vorrichtung wird zunächst die Antriebswelle so verschoben, daß der richtige Abstand zwischen der feststehenden Lochplatte und dem entsprechenden Messer eingestellt wird. Anschließend wird dann die andere Lochplatte gegenüber dem auf ihr rotierenden Messer entsprechend nachgestellt, so daß in beiden Fällen beide Messer den gleichen Abstand zu den Lochplatten haben. Es besteht natürlich auch die Möglichkeit umgekehrt vorzugehen, wenn die verstellbare Lochplatte die größere Stärke aufweist. In diesem Fall wird diese Lochplatte zunächst auf den größten Abstand vom Messer eingestellt, dann die Antriebswelle so weit verschoben, bis das Messer den richtigen Abstand zur schwächeren Lochplatte aufweist, worauf man dann mit der verstellbaren Lochplatte entsprechend nachfährt. Auch wenn sich während des Betriebes der Abschliff der einen Lochplatte oder des entsprechenden Messers verändert, kann man die Einstellung ohne Abstellung der Vorrichtung entsprechend regulieren.According to the invention, this is the case with a comminution device described above achieved in that at least one perforated plate adjustable compared to the rotating knife is. With a device designed in this way, first the drive shaft moved so that the correct distance between the fixed perforated plate and the corresponding one Knife is set. Then the other then Perforated plate corresponding to the knife rotating on it readjusted so that both knives in both cases have the same distance to the perforated plates. Of course there is also the possibility to do the opposite if the adjustable perforated plate which has greater strength. In this In the first instance, this perforated plate is at the greatest distance from the Knife set, then the drive shaft moved so far, until the knife is at the correct distance from the weaker perforated plate has what you then with the adjustable perforated plate accordingly follows. Even if the Grind one perforated plate or the corresponding knife changed, you can change the setting without turning off the device regulate accordingly.

Vorzugsweise erfolgt die Verstellung der Lochplatte über einen gesonderten Stellmotor. Dabei ist es zweckmäßig, die Lochplatte auf einem Ring zu befestigen, welcher drehbar mit einem an seinem Außenumfang vorgesehenen Gewinde in ein an einer Gehäuseinnenwand vorgesehenes entsprechendes Gewinde eingreift. Durch Drehung dieses Ringes erfolgt dann eine Längsverstellung durch das Gewinde. Der Ring ist zusätzlich mit einem Zahnkranz versehen, in welchen ein Antriebsritzel eingreift. Bei Zerkleinrungsvorrichtungen, bei welchen Staufinger für das Zerkleinerungsgut vorgesehen sind, kann der Ring, welcher die Lochplatte trägt, gleichzeitig mit diesen Staufingern versehen sein. Der Verstellmotor wirkt zweckmäßigerweise über eine Rutschkupplung auf das Ritzel ein.The perforated plate is preferably adjusted via a separate servomotor. It is advisable to use the perforated plate to attach to a ring, which rotates with one on its The outer circumference is provided in a thread on a housing inner wall provided appropriate thread engages. By Rotation of this ring is then carried out by longitudinal adjustment the thread. The ring is also provided with a ring gear, in which a drive pinion engages. With shredding devices, which jam finger for the shredded material are provided, the ring, which is the perforated plate carries, at the same time be provided with these jam fingers. Of the Adjustment motor expediently works via a slip clutch on the pinion.

Die Vorrichtung besteht aus einem Einlaufgehäuse 1 mit einem aufgesetzten Trichter 2. Das nicht dargestellte über den Trichter 2 in das Einlaufgehäuse 1 eingefüllte Zerkleinerungsgut wird in das eigentliche Zerkleinerungsgehäuse 3 umgelenkt. In diesem befinden sich hintereinander angeordnet zwei Lochplatten 4 und 5, auf denen Messer 6 und 7 rotieren. Diese Messer sind auswechselbar an den Messerköpfen 8 und 9 befestigt. Beide Messerköpfe 8 und 9 sind fest mit der Welle 10 verbunden, welche über einen im Motorgehäuse 11 gelagerten Motor 12 angetrieben wird. Die Welle 10 ist in axialer Richtung verschiebbar gelagert. Ihr freies Ende 13 ist über ein Kugellager 14 in einer Gewindebuchse 15 angeordnet, welche ihrerseits in ein entsprechendes Innengewinde einer Querwand 16 eingreift. Durch verdrehen der Gewindebuchse 15 kann dann die axiale Verschiebung der Welle 10 erfolgen. Hierzu ist ein Stellmotor 17 angeordnet, welcher über eine Rutschkupplung 18 auf ein Kettenrad 19 einwirkt. Dieses Kettenrad 19 überträgt die Drehbewegung durch eine nicht dargestellte Kette auf ein zweites Kettenrad 20, das seinerseits mit der Buchse 15 fest verbunden ist. Während sich die in Durchlaufrichtung des Zerkleinerungsgutes hintere Lochplatte 4 in axialer Richtung fest im Zerkleinerungsgehäuse 3 angeordnet ist, ist die vordere Lochplatte 5 auf einem in axialer Richtung verschiebbaren Ring 21 befestigt. Dieser Ring 21 greift mit seinem Gewinde 22 in ein entsprechendes Gewinde 23 der Außenwand 24 des Zerkleinerungsgehäuses 3 ein. Durch Verdrehen des Rings 21 wird dann die Lochplatte 5 in axialer Richtung zum oder gegen das Messer 7 verschoben. Hierzu ist der Ring 21 in seinem hinteren Teil mit einem Zahnkranz 25 versehen, in welchen ein Ritzel 26 eingreift. Dieses wird über eine Rutschkupplung 27 und ein Kettentrieb 28 von einem zweiten Stellmotor 29 angetrieben. Der Ring 21 trägt gleichzeitig die Staufinger 30.The device consists of an inlet housing 1 with a attached funnel 2. The not shown over the funnel 2 shredded material filled into the inlet housing 1 is deflected into the actual shredding housing 3. In two perforated plates are arranged one behind the other 4 and 5, on which knives 6 and 7 rotate. These knives are interchangeably attached to the cutter heads 8 and 9. Both cutter heads 8 and 9 are fixed to the shaft 10, which driven by a motor 12 mounted in the motor housing 11 becomes. The shaft 10 is slidably mounted in the axial direction. Your free end 13 is a ball bearing 14 in one Threaded bushing 15 arranged, which in turn in a corresponding Internal thread of a transverse wall 16 engages. By twisting the threaded bush 15 can then the axial displacement of the Wave 10 take place. For this purpose, a servomotor 17 is arranged which acts on a sprocket 19 via a slip clutch 18. This sprocket 19 transmits the rotary movement through a Not shown chain on a second sprocket 20, the is in turn firmly connected to the socket 15. While the perforated plate at the rear in the direction of flow of the comminution material 4 fixed in the axial direction in the shredding housing 3 is arranged, the front perforated plate 5 is in an axial Attached to the movable ring 21. This ring 21 engages with its thread 22 in a corresponding thread 23 the outer wall 24 of the shredding housing 3. By twisting of the ring 21 is then the perforated plate 5 in the axial direction moved to or against the knife 7. For this is the Ring 21 provided in its rear part with a ring gear 25, in which a pinion 26 engages. This is about a Slip clutch 27 and a chain drive 28 from a second Servomotor 29 driven. The ring 21 carries the Staufinger 30

Zur Einstellung des Abstandes zwischen den Lochplatten 4 und 5 einerseits und den Messern 6 und 7 andererseits wird zunächst die Messerwelle 10 über den Stellmotor 17 so weit verschoben, bis das Messer 6 auf der Lochplatte 4 anliegt. Anschließend wird dann der entsprechende Abstand zwischen dem Messer 7 und der Lochplatte 5 durch Verschiebung der letztgenannten über den zweiten Stellmotor 29 eingestellt. Damit ist die Grundstellung erreicht, welche beispielsweise in einem Computer gespeichert werden kann, so daß man sowohl beim Stillstand als auch beim Arbeitsvorgang der Vorrichtung von dieser Grundstellung ausgehend, beliebige Abstände einstellen kann.To adjust the distance between the perforated plates 4 and 5 on the one hand and the knives 6 and 7 on the other hand will first the knife shaft 10 has been displaced so far via the servomotor 17, until the knife 6 rests on the perforated plate 4. Subsequently then the corresponding distance between the knife 7 and the perforated plate 5 by moving the latter over the second actuator 29 set. This is the basic position achieved, which is stored for example in a computer can be, so that one both at standstill and at Operation of the device starting from this basic position, can set any distances.

Sofern die vordere Lochplatte 5 wesentlich stärker sein sollte als die hintere 4, wird zunächst die vordere Lochplatte 5 auf den größten Abstand vom Messer 7 verschoben und erst dann die Messerwelle 10 in die entsprechende Lage gebracht. Anschließend wird dann die Lochplatte 5 wiederum gegen das Messer 7 verschoben bis der richtige Abstand eingenommen ist.If the front perforated plate 5 should be much stronger than the rear 4, the front perforated plate 5 is first on moved the greatest distance from the knife 7 and only then Knife shaft 10 brought into the appropriate position. Subsequently the perforated plate 5 is then moved again against the knife 7 until the correct distance is taken.
