Description

Die Erfindung betrifft eine Vorrichtung zum Zcrkleinen flächiger Erzeugnisse, insbesondere von plattenförmigen zähelastischen Stoffen, bestehend aus zwei achsparallel angeordneten, zusammenwirkenden Schneidrotoren, die aus in axialen Abständen angeordneten Zahuscheiben bestehen, die aus dem Grundkörper des Rotors radial herausragen und sich mit den Seitenflanken der Zahnscheiben des jeweils anderen Rotors dicht scherend überschneiden. The invention relates to a device for reducing surface areas Products, in particular consisting of sheet-like tough elastic materials from two axially parallel, interacting cutting rotors, which are made of in Axial spacings arranged counters, which consist of the base body of the The rotor protrudes radially and is connected to the side flanks of the toothed disks of the respective overlap the other rotor in a tightly sheared manner.

Bei den bekannten Maschinen dieser Art gelangt das zu zerkleinernde Gut zwischen mit verschiedener Umfangsgeschwindigkeit umlaufende Rotoren, deren Zähne im wesentlichen reißen. Die anfallenden Stücke sind sehr ungleichmäßig, auch wenn die ineinandergreifenden Zahnscheiben der Rotoren so eng stehen, daß an den Seitenflanken ein scherender Schnitt erzielt wird. In the known machines of this type, the material to be shredded arrives Good between rotors rotating at different peripheral speeds, their Teeth essentially tear. The accruing pieces are very uneven, too when the interlocking toothed discs of the rotors are so close that the Side flanks a shearing cut is achieved.

Um plattenförmige Stoffe in gleichmäßige Stücke aufzuspalten, sind mit Zähnen besetzte Rotoren bekannt, die die Stücke an der Stirnkante eines Auflagetisches abscheren. Diese Maschinen scheren hackend im Bereich eines kleinen Drehwinkels und müssen mit sehr genauer Lagerung für den Rotor ausgerüstet sein. In order to split sheet-like substances into even pieces, are Rotors studded with teeth known, which the pieces on the front edge of a support table shear. These machines shear by chopping in the area of a small angle of rotation and must be equipped with very precise bearings for the rotor.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine Schneidmaschine für plattenförmige zähelastische Stoffe zu schaffen, die bei großer Leistung und ruhigem Lauf gleichmäßige Stücke hinsichtlich der Größe liefert. The object on which the invention is based is to provide a cutting machine for creating plate-shaped viscoplastic materials that perform at high levels and smooth running delivers even pieces in terms of size.

Erfindungsgemäß wird das dadurch erreicht, daß die Zähne der Zahnscheiben nach Art üblicher Stirnzahnräder ausgebildet und in axial fluchtenden Zahnreihen derart zueinander angeordnet sind, daß je zwei zusammenwirkende Zahnreihen der beiden Rotoren gleichzeitig in die Überschneidungszone einlaufen. According to the invention this is achieved in that the teeth of the toothed disks designed in the manner of conventional spur gears and in axially aligned rows of teeth are arranged to each other that two cooperating rows of teeth of the two The rotors enter the overlap zone at the same time.

Beim Einzug einer Platte oder einer Bahn zwischen die Rotoren tritt bei dieser Anordnung zunächst eine Querteilung ein, indem die Zahnköpfe gleichzeitig und parallel zu den Drehachsen der Rotoren abwechselnd von beiden Seiten her in den Werkstoff eindringen und diesen aufspalten. Bei weiterer Drehung wird mit den Seitenkanten der Zähne beim Eindringen in die Lücken des Gegenrotors der Werkstoff bis zu der von den vorhergehenden Zahnköpfen in Querrichtung gebildetem Schnitt abgeschert. Es entstehen dabei Stücke von annähernd der Länge, die den Abstand zwischen zwei Zahnköpfen ausmacht und die untereinander völlig gleich sind. Durch die Gleichstellung der Zähne beider Rotoren erfolgt das Aufspalten des Werkstoffes quer zur Bewegungsrichtung (also parallel zu den Drehachsen) vor dem Aufspalten in der Bewegungsrichtung, das über einen Drchwinkel von mehr als 300 langsam erfolgt. Es müssen sich die Fußpunkte aller Zahnlücken, die auf den Fußkreisen liegen, beim Abwälzen decken, also alle in axial fluchtenden Zahnreihen liegen. Occurs when a plate or a web is drawn in between the rotors With this arrangement, first a transverse division by the tooth tips at the same time and parallel to the axes of rotation of the rotors alternately from both sides in penetrate the material and split it. With further rotation the Side edges of the teeth when penetrating the gaps in the counter rotor of the material up to the transverse section formed by the previous tooth tips sheared off. This creates pieces of approximately the length that the distance between make up two tooth heads and which are completely identical to each other. Through equality of the teeth of both rotors, the splitting of the material takes place transversely to the direction of movement (i.e. parallel to the axes of rotation) before splitting in the direction of movement, the takes place slowly over a twist angle of more than 300. It must be the base points cover all tooth gaps that lie on the root circles when rolling, i.e. all lie in axially aligned rows of teeth.

Demgemäß laufen je zwei zusammenwirkende Zahnreihen der Rotoren gleichzeitig -n die thberschneidungszone ein, und dieser Synchronlauf kann durch cinc Antriebsverbindung, z. B. Zahnräder, erreicht werden.Accordingly, two cooperating rows of teeth of the rotors run at the same time -n the intersection zone, and this synchronous operation can be achieved by cinc drive connection, z. B. gears can be achieved.

Dic Rotoren werden in bekannter Weise zweckmäßig so herrestellt, daß auf eine Achse in abwechselnder F>lge gezahnte Scheiben und Distanzscllcil,cn befestigt werden. The rotors are expediently produced in a known manner so that that on an axis in alternating direction toothed disks and spacers, cn be attached.

Icrner werden an der Auslaufseite der Rotoren zweckmäßig kammartige, in Zwischenräume greifende Abstreifer parallel zur Durchlaufr -htung des Gutes angeortlnet. Icrner are expediently comb-like, reaching into spaces The scraper is arranged parallel to the direction in which the goods flow.

Für eine gienstige Wirkung der Zerkleinerungsvorrichtung s=r (l 11 die Rotoren nebeneinander angeordnet und so angetrieben, daß das Gut in Richtung der Schwerkraft bewegt wird. For a good effect of the shredding device s = r (l 11 the rotors arranged side by side and driven so that the material in the direction moved by gravity.

Die Zähne werden am Kopfende vorteilhaft mit Schneiden versehen, die parallel zu den Drehachsen der Rotoren liegen, um das Eindringen in den Werkstoff zu erleichtern. The teeth are advantageously provided with cutting edges at the head end, which are parallel to the axes of rotation of the rotors to prevent penetration into the material to facilitate.

Ein Ausführungsbeispiel der Erfindung wird durch die Zeichnung veranschaulicht. An embodiment of the invention is illustrated by the drawing.

Auf den beiden Wellen 1 und 2, die mit gleicher Drehzahl und in entgegengesetzter Drehrichtung betrieben werden, sind in abwechselnder Folge Zahnscheibe 3 und Distanzscheiben 4 angeordnet. Eine Distanzscheibe 3 liegt jeweils einer Zahnscheibe 4 des anderen Rotors gegenüber, und die Breite ist annähernd übereinstimmend, so daß beim Durchgang einer Zahnscheibe durch die Lücken des Gegenrotors eine Scherung erzielt wird. Im dargestellten Ausführungsbeispiel tangieren die beiden Fußkreise 5 und 6, und die Fußpunkte 7 kommen am Berührungspunkt 8 zur Deckung. Die zum Zerkleinern den Rotoren zugeführte Platte 9 wird an der StellelO durch die sich gegenüberliegenden Zähne 11 in Querrichtung, d. h. parallel zu den Drehachsen 12 aufgespalten, während bei weiterer Drehung die Kanten der Zähne den Werkstoff in Bewegungsrichtung abscheren. Zum Herauslösen der Stücke aus den Lücken sind kammartige Abstreifer 13 an der Ausgangsseite der Walzen vorgesehen. On the two shafts 1 and 2, which are at the same speed and in opposite directions Direction of rotation are operated in alternation with toothed disk 3 and spacer disks 4 arranged. A spacer 3 lies in each case with a toothed disk 4 of the other Rotor opposite, and the width is approximately the same, so that when passing a toothed disk through the gaps in the counter rotor a shear is achieved. in the The illustrated embodiment are tangent to the two root circles 5 and 6, and the Foot points 7 come to cover at the point of contact 8. The one used to crush the rotors supplied plate 9 is at the StellelO by the opposing teeth 11 in the transverse direction, i.e. H. split parallel to the axes of rotation 12, while at further rotation, the edges of the teeth shear off the material in the direction of movement. To remove the pieces from the gaps, there are comb-like scrapers 13 on the output side of the rollers provided.

Bei der Verarbeitung von sehr zähem Werkstoff kann der Abstand der Achsen 12 verringert werden, so daß sich die Fußkreise 5 und 6 schneiden und sich die Fußpunkte 7 bei jedem Umlauf jeweils zweimal mit den Fußpunkten der Zähne des anderen Rotors treffen. When processing very tough material, the distance of the Axes 12 are reduced so that the root circles 5 and 6 intersect and each other the base points 7 each time twice with the base points of the teeth of the meet another rotor.
