Description

Die Erfindung bezieht sich auf eine Schneidvorrichtung für mindestens zweilagige Flächengebilde, insbesondere in Schuppen­form durch eine Transportvorrichtung herangeführte Papierpro­dukte, mit einem rotierenden Schneidmesser und einem gegenläufig rotierenden, letzteres in der Schneidebene teilweise überlappen­den Gegenmesser und einer im Schneidbereich vorgesehenen Preß­vorrichtung für die Flächengebilde.The invention relates to a cutting device for at least two-ply flat structures, in particular in the form of scales brought by a transport device, with a rotating cutting knife and a counter-rotating counter-knife, the latter partially overlapping in the cutting plane, and a pressing device provided in the cutting area for the flat structures.

Schneidvorrichtungen, insbesondere für in Schuppenform durch Transportbänder herangeführte Papierprodukte bestehen gewöhn­lich aus einem rotierenden Schneidmesser, welches entweder rund geschliffen ist oder auch Zähne, z.B. in Sägezahnform, aufweist, oder auch mit verschiebbaren Klingen versehen ist (Patentanm. P 37 19 721.5 des Anmelders vom 12. Juni 1987), und einem Gegenmesser, welches einen zylindrischen Rand auf­weist und Preßbändern, die im Schneidbereich dafür sorgen, daß die einzelnen Papierprodukte so festgehalten werden, daß ein möglichst glatter Schnitt erzielt wird. Die Gegenmesser dienen somit einerseits als Auflagefläche oder Widerlager für die Papierprodukte und andererseits als Anlagefläche für das Schneidmesser im überlappenden Bereich. Aufgrund der Tatsache, daß insbesondere bei in Schuppenform herangeführten Papier­produkten jeweils durch die Unterkante des untersten Papier­produktes in bezug auf die Unterfläche des nächst oberen Papierproduktes an der schneidmesserabgekehrten Seite ein sehr kleiner Hohlraum entsteht, kommt es insbesondere bei dickeren Papierprodukten zu kleinen "Ausfransungen" in diesem Bereich, was nicht nur dazu führt, daß eine absolut glatte Abschluß­kante des Papierprodukts nach dem Schnitt nicht erreichbar ist, sondern auch dazu, daß diese Schnittunregelmäßigkeiten sich bei dickeren Papierprodukten unterschiedlich von oben nach unten ergeben.Cutting devices, in particular for paper products brought in in the form of scales by conveyor belts, usually consist of a rotating cutting knife which is either ground round or has teeth, for example in the shape of a saw tooth, or is also provided with displaceable blades (patent application P 37 19 721.5 of the applicant of 12 June 1987), and a counter knife, which has a cylindrical edge and press belts, which ensure in the cutting area that the individual paper products are held in such a way that the cut is as smooth as possible. The counter knives thus serve on the one hand as a contact surface or abutment for the paper products and on the other hand as a contact surface for the cutting knife in the overlapping area. Due to the fact that in particular in the case of paper products brought in in the form of scales, a very small hollow space is created on the side facing away from the cutting knife by the bottom edge of the bottom paper product in relation to the bottom surface of the next top paper product, small "fraying" occurs in this, particularly in the case of thicker paper products Area, which not only means that an absolutely smooth end edge of the paper product cannot be reached after the cut, but also that these cut irregularities result differently from top to bottom in the case of thicker paper products.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidvorrich­tung der eingangs erwähnten Art zu schaffen, mit der Unregel­mäßigkeiten am beschnittenen oder besäumten Rand der Papier­produkte, insbesondere wenn es sich um sogen. dickere Papier­produkte handelt, vermieden werden.The invention has for its object to provide a cutting device of the type mentioned, with the irregularities on the trimmed or trimmed edge of the paper products, especially when it comes to so-called. thicker paper products are avoided.

Die Aufgabe wird dadurch gelöst, daß erfindungsgemäß das Gegen­messer eine in die Schneidebene hineinragende Schneidkante und eine axial verlaufende Auflagefläche für die Flächengebilde aufweist.The object is achieved in that, according to the invention, the counter knife has a cutting edge projecting into the cutting plane and an axially extending contact surface for the flat structures.

Während an sich grundsätzlich eine derartige Auflagefläche bei Gegenmessern bekannt ist, ist die Verwendung bei einer Schneid­kante am Gegenmesser, insbesondere im Zusammenhang mit einzeln herangeführten, in Schuppenform transportierten Papierprodukten neu. Die Schneidkante soll dabei nur eine relativ geringe Er­ streckung in radialer Richtung haben, vor allem um den oben angegebenen Unzulänglichkeiten beim Schnitt, insbesondere von dickeren Papierprodukten gerecht zu werden.While such a contact surface is generally known in the case of counter knives, the use of a cutting edge on the counter knife is new, in particular in connection with individually introduced paper products transported in the form of scales. The cutting edge should only be a relatively small Er stretch in the radial direction, especially to meet the above-mentioned shortcomings in cutting, especially of thicker paper products.

Nach einer bevorzugten Ausführungsform der Erfindung ist die Auflagefläche an einem die Rückseite des Gegenmessers bilden­den Ring o.dgl. vorgesehen. Die Schneidkante kann mit der Schneidebene einen Winkel von ca. 1 - 5°, vorzugsweise ca. 3°, aufweisen. Auch kann die Schneidkante an ihrer der Auflage­fläche zugekehrten Seite einen Winkel von ca. 13 - 19°, vor­zugsweise ca. 16°, einschließen.According to a preferred embodiment of the invention, the bearing surface or the like on a ring forming the back of the counter knife. intended. The cutting edge can have an angle of approximately 1-5 °, preferably approximately 3 °, with the cutting plane. The cutting edge can also enclose an angle of approximately 13-19 °, preferably approximately 16 °, on its side facing the contact surface.

Nach einer besonders bevorzugten Ausführungsform der Erfindung weist der Ring eine Tiefe von ca. 4 - 8 mm, vorzugsweise ca. 6 mm, und in radialer Richtung eine Breite von ca. 12 - 20 mm, vorzugsweise ca. 16 mm, auf. Es liegt auf der Hand, daß diese Angaben Parameter des benutzten Gegenmessers und auch des größeren Schneidmessers sind. Gewöhnlich ist das Schneidmesser wesentlich größer als das sogen. Gegenmesser, dabei sind Durchmesser des Schneidmessers zwischen 250 und 320 mm und des Gegenmessers von ca. 150 mm üblich.According to a particularly preferred embodiment of the invention, the ring has a depth of approximately 4-8 mm, preferably approximately 6 mm, and in the radial direction a width of approximately 12-20 mm, preferably approximately 16 mm. It is obvious that these details are parameters of the counter knife used and also of the larger cutting knife. Usually the cutting knife is much larger than the so-called. Counter knife, the diameter of the cutting knife between 250 and 320 mm and the counter knife of about 150 mm are common.

Vorzugsweise erstreckt sich die Schneidkante ca. 2 - 6 mm, vor­zugsweise ca. 4 mm, in radialer Richtung. Hierbei soll vor allem der Tatsache Rechnung getragen werden, daß die Länge der Schneidkante in radialer Richtung annähernd der Stärke eines Papierproduktes angepaßt sein kann.The cutting edge preferably extends approximately 2-6 mm, preferably approximately 4 mm, in the radial direction. The fact that the length of the cutting edge in the radial direction can approximately be adapted to the thickness of a paper product should be taken into account here.

Das Gegenmesser kann mindestens im Schneidkantenbereich aus Hartmetall bestehen; dabei kann beispielsweise das unter der Bezeichnung G 20 bekannte Material Verwendung finden.The counter knife can be made of hard metal at least in the cutting edge area; the material known under the designation G 20 can be used, for example.

Der von dem Ring begrenzte Bereich des Gegenmessers ist zweck­mäßigerweise als dünne Platte ausgebildet.The area of the counter knife delimited by the ring is expediently designed as a thin plate.

Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung dargestellt; sie wird nachfolgend näher beschrieben. Es zeigt:

  • Fig. 1 eine Schneidvorrichtung in stark schematisierter Dar­stellung von der Seite gesehen,
  • Fig. 2 einen Querschnitt durch diese Schneidanlage,
  • Fig. 3 ein Detail von Fig. 1 in vergrößertem Maßstab,
  • Fig. 4 eine Seitenansicht in stark schematisierter Darstel­lung auf eine Ausführungsform der Erfindung,
  • Fig. 5 einen Querschnitt durch die Ausführungsform nach Fig. 4 und
  • Fig. 6 ein stark vergrößertes Detail von Fig. 5.
In the drawing, an example embodiment of the invention is shown; it is described in more detail below. It shows:
  • 1 is a cutting device seen in a highly schematic representation from the side,
  • 2 shows a cross section through this cutting system,
  • 3 shows a detail of FIG. 1 on an enlarged scale,
  • 4 is a side view in a highly schematic representation of an embodiment of the invention,
  • Fig. 5 shows a cross section through the embodiment of Fig. 4 and
  • FIG. 6 shows a greatly enlarged detail from FIG. 5.

Eine Schneidvorrichtung 1 für eine Rotationsschneidanlage von in Schuppenform in Pfeilrichtung 3 herangeführten Papier­produkten 2 besteht aus einem Schneidmesser 4 und einem Gegen­messer 5. Mit strichierten Linien ist eine obere Preßvorrich­tung 6 und eine untere Preßvorrichtung 7 angedeutet, die z.B.je aus kontinuierlich um zwei Walzen umlaufenden Endlosbändern bestehen;durch diese Preßvorrichtung 6 bzw. 7 werden die in Schuppenform herangeführten Papierprodukte 2 im Schneidbe­reich, wie mit den Pfeilen 8 und 9 angedeutet, zusammenge­halten, so daß ein einwandfreier Schnitt erfolgen kann.A cutting device 1 for a rotary cutting system of paper products 2 brought up in a scale shape in the direction of the arrow 3 consists of a cutting knife 4 and a counter knife 5. With broken lines, an upper pressing device 6 and a lower pressing device 7 are indicated, which consist, for example, of continuous belts continuously rotating around two rollers by means of this pressing device 6 and 7 the paper products 2 brought up in scale form are held together in the cutting area, as indicated by the arrows 8 and 9, so that a perfect cut can be made.

Üblicherweise sind die unteren dem Gegenmesser 5 zugeordne­ten Preßbänder 7 stationär, also unbeweglich angeordnet, während die Preßbänder 8, die dem Schneidmesser 4 zugeordnet sind, federnd gelagert sind.Usually, the lower press belts 7 assigned to the counter knife 5 are stationary, that is to say immovable, while the press belts 8, which are assigned to the cutting knife 4, are spring-mounted.

Das Schneidmesser 4, z.B. mit einem Durchmesser von 300 mm, ist wie insbesondere aus Fig. 3 ersichtlich ist, in bezug auf das Gegenmesser 5 versetzt angeordnet, wobei der über­lappende Bereich 10 in radialer Richtung entsprechend dem dargestellten Ausführungsbeispiel 6 - 7 mm betragen kann, in jedem Fall jedoch größer ist als die Stärke eines Papier­produkts 2.The cutting knife 4, e.g. With a diameter of 300 mm, as can be seen in particular from FIG. 3, is arranged offset with respect to the counter knife 5, the overlapping region 10 in the radial direction according to the exemplary embodiment shown being 6 to 7 mm, but in any case larger is as the strength of a paper product 2.

Die Stärke des Papierprodukts 2 beträgt beim Ausführungsbei­spiel ca. 4 mm, so daß auch die Schneidkante 20 des Gegen­messers 5 ca. 4 mm in radialer Richtung vorsteht. Auf diese Weise ist gewährleistet, daß der Hohlraum 21 durch eine Schneidkante erfaßt wird. Dieser dreieckförmige Hohlraum 21 ergibt sich zwischen der Rückseite 22 des untersten Papier­produktes 2 einerseits, der Unterseite 23 des nächstoberen Papierproduktes und dem Preßband 7 der unteren Preßvorrich­tung.The thickness of the paper product 2 is approximately 4 mm in the exemplary embodiment, so that the cutting edge 20 of the counter knife 5 also projects approximately 4 mm in the radial direction. In this way it is ensured that the cavity 21 is gripped by a cutting edge. This triangular cavity 21 results between the back 22 of the bottom paper product 2 on the one hand, the bottom 23 of the next top paper product and the press belt 7 of the lower press device.

Wie insbesondere aus Fig. 5 ersichtlich ist, ist die Schneid­kante 20 des Gegenmessers 5 aus dem gleichen Material herge­stellt, wie ein Ring 30, dessen zylindrische Außenfläche 31 als Auflage für die Papierprodukte ausgebildet ist.As can be seen in particular from FIG. 5, the cutting edge 20 of the counter knife 5 is made of the same material as a ring 30, the cylindrical outer surface 31 of which is designed as a support for the paper products.

Bei der dargestellten Ausführungsform hat der Ring 30 folgende Abmessungen: seine radiale Länge 31 beträgt 16 mm und seine Breite in axialer Richtung 6 mm.In the embodiment shown, the ring 30 has the following dimensions: its radial length 31 is 16 mm and its width in the axial direction 6 mm.

In Bezug auf die Schneidebene 33 ist die Schneidkante 20 um einen Winkel 37 von 3° abgeschrägt. Die Rückseite 35 der Schneidkante schließt einen Winkel 36 von 16° ein.With respect to the cutting plane 33, the cutting edge 20 is chamfered by an angle 37 of 3 °. The back 35 of the cutting edge forms an angle 36 of 16 °.

Gewöhnlich wird das Schneidmesser 4 als Obermesser und das Gegenmesser 5 als Untermesser eingesetzt. Während das Unter­messer 5 mindestens eine Tangentialgeschwindigkeit gleich der Geschwindigkeit des Transportbandes haben sollte, läuft das Schneidmesser mit einer mindestens 10%ig höheren Tangential­geschwindigkeit.Usually the cutting knife 4 is used as the upper knife and the counter knife 5 as the lower knife. While the lower knife 5 should have at least one tangential speed equal to the speed of the conveyor belt, the cutting knife runs with an at least 10% higher tangential speed.
