Abstract
Verfahren zum Schneiden von in einem Schuppenstrom (17) geförderten Papierprodukten (16, 18) mit zwei Rotationsschneidmessern (10, 12), die jeweils einen runden Grundkörper aufweisen, an dessen Außenumfang eine Vielzahl von einzelnen Klingen (11, 11') vorgesehen ist, wobei die beiden Rotationsschneidmesser (10, 12) oberhalb und unterhalb des Schuppenstromes (17) so angeordnet werden, daß die Klingen (11) des einen Rotationsschneidmessers (10) mit den Klingen (11') des anderen Rotationsschneidmessers (12) überlappen und ineinander kämmen, so daß die Klingen (11, 11') beim Schneiden abwechselnd von oben und von unten in den Schuppenstrom (17) eingreifen.method for cutting in a scale flow (17) promoted Paper products (16, 18) with two rotary cutting knives (10, 12), each one round basic body have, on the outer circumference a plurality of individual blades (11, 11 ') is provided, wherein the two rotary cutting knives (10, 12) above and below of the scale flow (17) are arranged so that the blades (11) of a rotary cutting knife (10) with the blades (11 ') overlap the other rotary cutting blade (12) and mesh with each other, so that the Blades (11, 11 ') when cutting alternately from above and from below in the scale flow (17) intervene.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schneiden von in einem Schuppenstrom geförderten Papierprodukten mit einem Rotationsschneidmesser.The The invention relates to a method and a device for cutting of conveyed in a shingled stream Paper products with a rotary cutter.

Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zum Schneiden von in einem Schuppenstrom geförderten Papierprodukten zu schaffen, mit denen ein gleichmäßiges Schnittbild erzielt werden kann.It is the object of the present invention, a method and a Apparatus for cutting paper products conveyed in a shingled stream to create a uniform cross-sectional image can be achieved can.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale der unabhängigen Ansprüche.The solution This object is achieved by the features of the independent claims.
In den Figuren zeigen:In show the figures:
Bei dieser Ausführungsform kann es vorteilhaft sein, wenn die positive Schuppe stets mittig durch die beiden Rotationsschneidmesser läuft, da kein stützendes Untermesser vorgesehen ist. Auch ist es vorteilhaft, wenn der Abstand des oberen und des unteren Rotationsschneidmessers einstellbar ist, um verschieden dicke Schuppen zu berücksichtigen. Hierzu kann die zum Anpressen der Schuppe vorgesehene untere Rollenleiste auf die Schuppendicke einstellbar sein, was eine technisch einfache Lösung darstellt. Es können jedoch auch Einrichtungen vorgesehen sein, welche die Pressbandrollen symmetrisch zur Schuppenmitte öffnen. Hierdurch ist keine Einstellung der Schuppendicke erforderlich und die Schuppe verläuft genau mittig zu dem oberen und dem unteren Rotationsschneidmesser. Auch können die Pressbandrollenleisten so ausgestaltet sein, dass diese nach oben und nach unten symmetrisch öffnen.at this embodiment It may be advantageous if the positive scale is always centered the two rotary cutter is running as no supporting Lower blade is provided. Also it is beneficial if the distance of the upper and lower rotary cutter is adjustable to to consider different thick scales. For this purpose, the for pressing the scale provided lower roller bar on the Scallop thickness be adjustable, which represents a technically simple solution. It can However, facilities may be provided which the press belt rolls open symmetrically to the center of the shed. As a result, no adjustment of the scale thickness is required and the scale runs exactly in the middle of the upper and lower rotary cutting knives. Also, the Press belt roller rails be designed so that these upwards and open symmetrically downwards.
Ferner kann jede Klinge zwei symmetrisch zur Mittelachse der Klinge verlaufende Schneidkanten aufweisen.Further each blade can run two symmetrically to the central axis of the blade Have cutting edges.
Obwohl vorstehend Rotationsschneidmesser mit darauf angeordneten Einzelklingen bzw. Einzelmessern beschrieben wurden, können sämtliche beschriebenen Ausführungsformen auch bei einstückig ausgebildeten Rotationsschneidmessern Anwendung finden.Even though above rotary cutting knife with individual blades arranged thereon or individual blades have been described, all described embodiments even with one piece trained rotary cutting knives application.
Ferner
ist es bei Produkten mit einem Falz vorteilhaft, wenn zunächst der
sogenannte Längsschnitt
durchgeführt
wird, d.h. der Schnitt parallel zu dem Falz. Hierdurch kann der
Schuppenstrom am darauffolgenden Kopf- und Fussschnitt ohne Einreißen am Schuppenstrom
geschnitten werden, wenn die untenliegenden Produkte
Die beschriebenen Schneidverfahren eignen sich besonders gut für Produktförderströme, deren Schuppe aus Produkten gebildet ist, die eine Mindestseitenzahl von 32 Seiten aufweisen. Die besten Ergebnisse wurden mit Produkten mit einer Seitenzahl von 96 Seiten erzielt.The Cutting methods described are particularly suitable for product flow rates, their scale made up of products that have a minimum page number of 32 pages exhibit. The best results were with products with one Page number of 96 pages achieved.
Bei der Anwendung der Schneidverfahren kann es erforderlich sein, den Produktstrom von oben bzw. von unten gefedert gegen das Gegenmesser zu drücken. Hierbei hat es sich als vorteilhaft erwiesen, das Gegendruckmesser nicht auf der Höhe der Förderebene sondern etwas oberhalb der Förderebene anzuordnen. Hierdurch ergibt sich bei Verwendung von Produktströmen mit einer relativ hohen Dicke ein gewisser Ausgleich.at It may be necessary to use the Product flow from above or from below sprung against the counter knife to press. It has proved to be advantageous, the counter pressure gauge not at the height the funding level but to arrange something above the conveying plane. This results when using product streams with a relatively high thickness a certain balance.
Auch kann es vorteilhaft sein, den Produktstrom durch eine federnd bewegliche Mittelstütze, beispielsweise eine Röllchenbahn zu unterstützen, die um eine horizontale Achse verschwenkbar gelagert sein kann. Diese verschwenkbare Röllchenbahn kann über eine Mitnehmerstange so bewegt werden, dass sie stets den Produktstrom unterstützt. Besonders vorteilhaft ist eine zusätzliche Andruckrolle, die den Produktstrom vor dem Einlauf zwischen die beiden Pressbänder innerhalb der Schneidstation andrückt.Also It may be advantageous to flow the product through a resiliently movable Central support, for example a roller conveyor to support that can be mounted pivotably about a horizontal axis. These swiveling roller conveyor can over a Mitnehmerstange be moved so that they are always the product flow supported. Particularly advantageous is an additional pinch roller, the Product flow in front of the inlet between the two press belts within presses the cutting station.
