Abstract

A cutting knife for a rotary cutting apparatus for multilayer isolated paper products with projections, for example in tooth form, projecting from a base body. The projections are formed as blades or the like displaceable in or on the base body and inclined with respect to a cutting plane; the faces of the blades lying in the cutting plane can be reground.

Description

Die Erfindung bezieht sich auf ein Schneidmesser für Rotationsschneidanlagen für Papier, insbesondere mehrlagige vereinzelte Papierprodukte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a cutting knife for rotary cutting systems for paper, in particular multilayer paper products according to the preamble of claim 1.

Aus der DE-A-35 36 989 ist ein Schneidmesser dieser Art bekannt; die einzeln radial angeordneten Klingen sind in Aussparungen an der Schneidebene zugekehrten Innenseite des Grundkörpers eingelötet.From DE-A-35 36 989 a cutting knife of this type is known; the individually radially arranged blades are soldered into recesses on the inside of the base body facing the cutting plane.

In Rotationsschneidanlagen werden gewöhnlich Rundmesser und entsprechende Gegenmesser zum Schneiden von Papierprodukten, z.B. in Schuppenform, verwendet. Neben diesen Schneidmessern sind auch solche mit radialen Vorsprüngen oder mit Sägezähnen (s. z.B. US-A-3 813 981) bekannt. Sämtliche Schneidmesser dieser Art sind in der Schneidfläche oder in den Schneidflächen nachschleifbar, was jedoch vor allem zur Folge hat, daß der Durchmesser der Schneidfläche verringert wird. Darüber hinaus haben sich diese bekannten Schneidmesser deshalb nicht besonders bewährt, weil deren Lebensdauer relativ gering ist.In rotary cutting systems, round knives and corresponding counter knives are usually used for cutting paper products, for example in the form of flakes. In addition to these cutting knives, those with radial projections or with saw teeth (see, for example, US Pat. No. 3,813,981) are also known. All cutting knives of this type can be resharpened in the cutting surface or in the cutting surfaces, which, however, has the main consequence that the diameter of the cutting surface is reduced. In addition, these known cutting knives have not been particularly successful because their service life is relatively short.

Der Erfindung liegt die Aufgabe zugrunde, die Lebensdauer von Schneidmessern der eingangs genannten Art zu erhöhen und gleichzeitig zu gewährleisten, daß der jeweils wirksame Radius der Schneidflächen auch nach einem etwaigen Nachschleifen unverändert bleiben kann.The invention has for its object to increase the life of cutting knives of the type mentioned and at the same time to ensure that the effective radius of the cutting surfaces can remain unchanged even after any regrinding.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Auch nach dem etwaigen Nachschleifen wird durch die Verschiebbarkeit der Klingen der Radius der Schleiffläche unverändert beibehalten.The radius of the grinding surface remains unchanged even after any regrinding.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Klingen im Längsschnitt rechteckig ausgebildet und bilden in Zahnform die Schneidfläche. Vorzugsweise schließen die Klingen mit der Schneidebene einen Winkel von 10 - 22°, vorzugsweise 16°, ein.According to a preferred embodiment of the invention, the blades are rectangular in longitudinal section and form the cutting surface in tooth form. The blades preferably form an angle of 10-22 °, preferably 16 °, with the cutting plane.

Voraussetzung für eine derartige Verschiebbarkeit der einzelnen Klingen ist eine kegelstumpfartige Ausbildung des Grundkörpers, gegebenenfalls können im Grundkörper Schulterflächen vorgesehen sein, um die jeweiligen Klingen in ihrer Ausgangsstellung rückwärtig abzustützen.A prerequisite for such displaceability of the individual blades is a truncated cone-like design of the base body, shoulder surfaces can optionally be provided in the base body in order to support the respective blades in their starting position backwards.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Klingen in länglichen Aussparungen des Grundkörpers verschiebbar gelagert.According to a preferred embodiment of the invention, the blades are slidably mounted in elongated recesses of the base body.

Nach einer weiteren Abwandlung der Erfindung schließen die Längsachsen der Klingen einen spitzen Winkel zum jeweiligen Radius des Grundkörpers ein; dieser Winkel kann 9 - 12°, vorzugsweise 9°, betragen.After a further modification of the invention, the Longitudinal axes of the blades make an acute angle to the respective radius of the base body; this angle can be 9-12 °, preferably 9 °.

Auch wenn die Zahl der zu verwendenden Klingen von der Größe des Schneidmessers abhängt, hat es sich herausgestellt, daß bei einem Schneidmesser mit einem Durchmesser von z.B. 32 cm 35 - 45, vorzugsweise 40 Klingen, auf den Umfang des Grundkörpers verteilt sein können.Even though the number of blades to be used depends on the size of the cutting knife, it has been found that with a cutting knife with a diameter of e.g. 32 cm 35-45, preferably 40 blades, can be distributed over the circumference of the base body.

Die Klingen sind zweckmäßigerweise ca. 3 - 5 mm, vorzugsweise 4 mm, stark. Auch können die die Klingen aufnehmenden länglichen Aussparungen in bezug auf einen ihnen zugeordneten Radius um ca. 25 - 31 mm, vorzugsweise 28 mm, parallel versetzt sein.The blades are expediently approx. 3-5 mm, preferably 4 mm, thick. The elongated recesses receiving the blades can also be offset in parallel by approximately 25-31 mm, preferably 28 mm, with respect to a radius assigned to them.

Vorzugsweise sind die Klingen in den länglichen Aussparungen durch zwei Schraubbolzen gehalten.The blades are preferably held in the elongated recesses by two screw bolts.

Als besonders zweckmäßig hat es sich erwiesen, daß die Klingen aus einem vom Grundkörper abweichenden besonders gehärtetem Stahl bestehen. Auf diese Weise ist es möglich, die Lebensdauer des Schneidmessers besonders gut zu verlängern, wobei der Grundkörper sogar noch bei vollständigem Ersatz der Klingen Verwendung finden kann.It has proven to be particularly expedient that the blades consist of a specially hardened steel which differs from the base body. In this way it is possible to extend the life of the cutting knife particularly well, the base body being able to be used even when the blades are completely replaced.

In den Zeichnungen ist ein Beispiel einer Ausführungsform der Erfindung schematisiert dargestellt; sie wird nachfolgend näher beschrieben. Es zeigt:

Fig. 2
einen Schnitt gemäß Linie 2-2 in Fig. 1 und
Fig. 3
ein Detail in vergrößertem Maßstab, ebenfalls in Draufsicht.
In the drawings, an example of an embodiment of the invention is shown schematically; it is described in more detail below. It shows:
Fig. 1
a plan view of this embodiment,
Fig. 2
a section along line 2-2 in Fig. 1 and
Fig. 3
a detail on an enlarged scale, also in plan view.

Ein Schneidmesser 1 mit einem Durchmesser 2 von annähernd 32 cm ist, wie aus Fig. 2 ersichtlich, kegelstumpfförmig ausgebildet, wobei die Fläche 3 in bezug auf die Schneidebene 4 einen Winkel 5 von 16° einschließt.A cutting knife 1 with a diameter 2 of approximately 32 cm is, as can be seen from FIG. 2, frustoconical, the surface 3 enclosing an angle 5 of 16 ° with respect to the cutting plane 4.

Der mittige kranzartig ausgebildete Bereich des Grundkörpers 6 weist eine ebenfalls konisch verlaufende Außenrandfläche 7 auf, die jedoch, wie insbesondere aus Fig. 2 ersichtlich, im Bereich der jeweiligen Klingen 8 Aussparungen 9 aufweist. Der Grundkörper 6 besteht aus einem für Schneidmesser üblichen Material; demgegenüber sind die Klingen 8 mit einer Stärke von 4 mm aus einem besonders gehärteten Stahl hergestellt.The central, ring-shaped region of the base body 6 has a likewise conical outer edge surface 7 which, however, as can be seen in particular from FIG. 2, has recesses 9 in the region of the respective blades 8. The base body 6 consists of a material customary for cutting knives; in contrast, the blades 8 are made with a thickness of 4 mm from a specially hardened steel.

Die Klingen 8 weisen in Draufsicht zumindest in bezug auf ihre Schneidfläche 10 hin einen rechteckigen Querschnitt auf, während sie an ihrem zur Mitte weisenden Ende 11 abgerundet sein können.The blades 8 have a rectangular cross-section in plan view, at least with respect to their cutting surface 10, while they can be rounded at their end 11 pointing towards the center.

Die Klingen 8 weisen jeweils einen Längsschlitz 12 auf, der - wie weiter unten näher beschrieben - zur Aufnahme von Schraubbolzen dient.The blades 8 each have a longitudinal slot 12, which - as described in more detail below - serves to receive screw bolts.

Während auf der einen Seite die Klingen 8 schräg in die Schneidebene 6 hineinragen und somit ihre nachschleifbare Fläche 13 in der Schneidebene 4 verläuft, ist auch durch eine Schrägstellung der Klingen 8 (s. Fig. 1) in bezug auf den jeweiligen Radius eine besondere Form der Schneidfläche erreicht, welche in diesem Fall einer Zahnform ähnelt.While on one side the blades 8 protrude obliquely into the cutting plane 6 and thus their regrindable surface 13 runs in the cutting plane 4, an inclined position of the blades 8 (see FIG. 1) also has a special shape with respect to the respective radius reached the cutting surface, which in this case resembles a tooth shape.

In bezug auf einen etwaigen Radius 15 ist bei der dargestellten Ausführungsform die zugeordnete Klinge 8′ um 28 mm versetzt. Dieses Maß ist mit dem Bezugszeichen 16 versehen.With respect to a possible radius 15, the associated blade 8 'is offset by 28 mm in the illustrated embodiment. This dimension is provided with the reference number 16.

Bei der dargestellten Ausführungsform sind 40 Klingen 8 vorgesehen, so daß sich der Mittelpunkt der Schnittfläche von zwei benachbarten Klingen jeweils um das Maß 17, d.h. 9°, beabstandet.In the illustrated embodiment, 40 blades 8 are provided, so that the center of the intersection of two adjacent blades is each around dimension 17, i.e. 9 °, spaced.

Die Klingen sind in nicht näher dargestellten Aussparungen 18 im Grundkörper verschiebbar gelagert, wobei jeweils zwei Schraubbolzen 19 und 20 die Klingen in Wirkstellung halten und die Verschiebbarkeit derselben gewährleisten.The blades are mounted displaceably in recesses 18, not shown, in the base body, two screw bolts 19 and 20 each holding the blades in the operative position and ensuring their displaceability.

Unter Berücksichtigung des radialen Abstandes von Klingenmittelpunkt zu Klingenmittelpunkt ergibt sich somit ein Maß 20′ in der Größe von 5 mm.Taking into account the radial distance from the center of the blade to the center of the blade, this results in a dimension 20 'in the size of 5 mm.

Dieses Schneidmesser kann als Einzelmesser oder vor allem in Rotationsschneidanlagen für mehrlagige Papierprodukte z.B. in Schuppenform zusammen mit einem entsprechenden Gegenmesser Verwendung finden. Dieses Gegenmesser, welches gewöhnlich als Untermesser ausgebildet ist, wirkt in der Schneidebene 4 mit der Schneidkante 13 der einzelnen Klingen zusammen.This cutting knife can be used as a single knife or especially in rotary cutting systems for multi-layer paper products e.g. in scale form can be used together with a corresponding counter knife. This counter knife, which is usually designed as a lower knife, cooperates in the cutting plane 4 with the cutting edge 13 of the individual blades.
