Description
Die Erfindung betrifft eine Vorrichtung zum Einstellen eines Messers gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for adjusting a knife according to the preamble of patent claim 1.
Derartige Vorrichtungen sind z. B. aus der DE 26 56 267 A1 bekanntgeworden. Mit der dort beschriebenen Einrichtung kann ein Schneidmesser zum Durchschneiden von mehreren Bogenlagen in radialer Richtung verstellt werden. Hierzu sind in Zylinderlängsachsenrichtung verschiebbare, keilförmige Mittel vorgesehen. Die radiale Verschiebung der Schneidmesser geschieht zusammen mit den Gegenschneidleisten eines benachbarten Zylinders, um bei geänderter Dicke der Bogenlagen immer einen optimalen Abstand zwischen Schneidmesser und Gegenschneidleiste zu gewährleisten und so gute Verhältnisse beim Transport der Bogenlagen durch den Falzapparat zu haben.Such devices are e.g. B. from DE 26 56 267 A1. With the device described there, a cutting knife for cutting through several sheet layers in the radial direction can be adjusted. For this purpose, wedge-shaped means displaceable in the longitudinal direction of the cylinder are provided. The radial displacement of the cutting knives takes place together with the counter-cutting bars of an adjacent cylinder, in order to always ensure an optimal distance between the cutting knife and counter-cutting bar when the thickness of the sheet layers changes, and thus to have good conditions when transporting the sheet layers through the folder.
Die Frage, in wieweit Schneidmesser oder Perforiermesser völlig außer Wirksamkeit zu stellen oder in Umfangsrichtung zu verstellen sind, wird in jener Druckschrift nicht angesprochen.The question of the extent to which cutting knives or perforating knives are to be rendered completely ineffective or to be adjusted in the circumferential direction is not addressed in that publication.
Durch die GB-A-3 96 486 ist eine Vorrichtung zum Einstellen eines Falzblattes auf einem ersten Zylinder zu Falzklappen auf einem zweiten Zylinder bekannt geworden. Durch diese Vorrichtung ist es möglich das Falzblatt in Zylinderumfangsrichtung zu verschieben und so genau auf den Falzspalt zwischen zwei Falzklappen des zweiten Zylinders einzustellen. Die Vorrichtung kann nur im Stillstand eingestellt werden.GB-A-3 96 486 discloses a device for setting a folding sheet on a first cylinder for folding flaps on a second cylinder. With this device it is possible To move the fold sheet in the cylinder circumferential direction and thus adjust it exactly to the fold gap between two fold flaps of the second cylinder. The device can only be adjusted when it is at a standstill.
Falzapparate müssen auf möglichst viele Produktionsarten umstellbar sein. So sind Falzapparate bekanntgeworden, deren Zylindergruppen umstellbar sind auf nur Schneiden, erster Querfalz, erster plus zweiter Querfalz oder Deltafalz. Hierzu müssen der Messerzylinder und der mit ihm Zusammenwirkende Gegenschneidleisten-Zylinder mehrere, unregelmäßig um ihren Umfang verteilte Messer bzw. Gegenschneidleisten oder beides aufweisen. So hat zum Beispiel der Messerzylinder drei Messer und eine Gegenschneidleiste und der Gegenschneidleisten-Zylinder ein Messer und drei Gegenschneidleisten.Folders must be convertible to as many types of production as possible. Folders have become known, the cylinder groups of which can be converted to only cutters, first cross fold, first plus second cross fold or delta fold. For this purpose, the knife cylinder and the counter-cutting bar cylinder interacting with it must have several knives or counter-cutting bars distributed irregularly around their circumference, or both. For example, the knife cylinder has three knives and one counter-cutting bar and the counter-cutting bar cylinder has one knife and three counter-cutting bars.
So wurden bisher nicht benötigte Messer ausgebaut und durch Füllstücke ersetzt. Diese Arbeiten mußten sehr sorgfältig bei Maschinenstillstand durchgeführt werden, weil nicht gut montierte Füllstücke eine Gefahr für das Bedienungspersonal bedeuten.Knives that were previously not required were removed and replaced with filler pieces. This work had to be carried out very carefully when the machine was at a standstill, because filler pieces that were not properly installed put the operating personnel at risk.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Halten eines Schneid- oder Perforiermessers auf einem Zylinder eines Falzapparates zu schaffen, mit dem es möglich ist, die Schneid- bzw. Perforierintensität stufenlos zu verstellen und/oder den Schnitteinsatz eines Schneidmessers bzw. die Perforierlinie auf die Falzlinie genau einzustellen.The invention has for its object to provide a device for holding a cutting or perforating knife on a cylinder of a folder, with which it is possible to continuously adjust the cutting or perforating intensity and / or the cutting insert of a cutting knife or the perforating line to adjust exactly to the fold line.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß sowohl die Schneid- bzw. Perforiermesserintensität als auch die Wirkungslinie von Schneid- bzw. Perforiermesser exakt eingestellt werden können.The advantages that can be achieved with the invention consist in particular in that both the cutting or perforating knife intensity and the line of action of the cutting or perforating knife can be set exactly.
Die erfindungsgemäße Vorrichtung kann leicht durch Anordnung von Motoren oder sonstigen Stelleinrichtungen fernverstellbar gemacht werden, so daß während des Betriebes das Messer in radialer und/oder Umfangsrichtung verstellt werden kann.The device according to the invention can easily be made remotely adjustable by arranging motors or other actuating devices, so that the knife can be adjusted in the radial and / or circumferential direction during operation.
Die Messer lassen sich leicht unter die Peripherie des Zylinders zurückziehen. Hierdurch können die Zylinder durch Anordnung mehrerer Messer um den Umfang verteilt für mehrere Produktionsarten ausgeführt sein. Nicht benötigte Messer können leicht, z. B. fernbetätigt, außer Wirkung (siehe oben) gestellt werden, ohne daß sie durch Füllstücke ersetzt werden müssen.The knives can easily be pulled back under the periphery of the cylinder. As a result, the cylinders can be designed for several types of production by arranging several knives distributed around the circumference. Knives that are not required can easily be z. B. remotely, be made ineffective (see above) without having to be replaced by fillers.
Außerdem ist es möglich, durch ein Verschieben von Schneidmessern in Umfangsrichtung auf einem Schneidmesserzylinder, - der mit einem Sammelzylinder zusammenwirkt -, Bogenlagen wahlweise "kurz - lang" zu schneiden, um so auch dickere gesammelte Produkte mit ineinanderliegenden Bogenlagen optisch einwandfrei erzeugen zu können, d. h. die innere Bogenlage steht nicht über die äußere Bogenlage hinaus.In addition, it is possible to shift sheet layers in the circumferential direction on a cutting knife cylinder, which cooperates with a collecting cylinder, to cut sheet layers optionally "short - long", in order to be able to produce thicker collected products with sheet layers lying one inside the other in an optically perfect manner . H. the inner sheet position does not protrude beyond the outer sheet position.

Ein Messerzylinder 1 besteht als Grundkörper 2 aus einem dickwandigen Rohr 3. An eine linke und rechte Stirnseite 4, 6 des Rohres 3 ist ein Lagerzapfen 7, 8 angeflanscht Der Lagerzapfen 8 weist eine konzentrische Bohrunq 9 auf, die in eine größere zylinderförmige Aussparung 11 mündet. Teilweise innerhalb der Aussparung 11 liegend ist eine Buchse 12 mit einer Keilführungsnut 13 an einen Einstich 14 an der rechten Stirnseite 6 angeschraubt. Eine ähnliche Buchse ist an die linke Stirnseite 4 des Rohres 3 angeschraubt. In jeweils einer Führungsbohrung der linken und rechten Buchse 12 ist eine Stellspindel 16 verschiebbar, jedoch nicht verdrehbar gelagert. Ein Keil 17 der Stellspindel 16 wird deshalb in der Keilführungsnut 13 geführt. Die Stellspindel 16 dient zur Erzeugung einer radialen Bewegung eines Schneid- oder Perforiermessers 18. An eine rechte Stirnseite 19 der Stellspindel 16 ist eine Schubstange 21 über einen Flansch 22 festgeschraubt. Ein zweites nicht dargestelltes Ende der Schubstange 21 ist z. B. unter Verwendung eines Druck-(Radial)lagers an eine dreh- und verschiebbare Stellwelle angekuppelt. Diese Stellwelle kann z. B. an ein Schraubengetriebe angekuppelt sein, das von einem drehrichtungsumkehrbaren Stellmotor - z. B. elektrisch oder pneumatisch angetrieben - fern angesteuert wird.A knife cylinder 1 consists of a thick-walled tube 3 as the
Auf einem Umfang der Stellspindel 16 ist in einer Längsnut 23 eine sich parallel zur Rotationsachse erstreckende Keilstange 24 befestigt. Hierbei ragen auf die Länge der Keilstange 24 verteilt, ihre Stellkeile 26 aus der Längsnut 23 nicht heraus. Die Keilstange 24 folgt also der Verschiebung der Stellspindel 16.A
Zwischen einer äußeren Führungsfläche 27 eines Bundes 25 der rechten Buchse 12 und einer Führungsfläche eines Bundes einer linken nicht dargestellten Buchse, und an den Führungsflächen entlanggleitbar angeordnet, ist eine Keilträgerstange 28 (Fig. 5). Sie trägt an ihrer Unterseite eine Mehrzahl von Gegenkeilstücken 29, deren Keile exakt an die jeweils mit ihnen zusammenwirkenden Stellkeile 26 angepaßt sind und in die Längsnut 23 hineinragen. Die Keilträgerstange 28 ist in Längsachsenrichtung mit einer Mehrzahl von Sacklöchern 31 versehen, in denen sich jeweils ein Teil einer Druckfeder 32 befindet, die einen Zwischenraum 33 durchdringt und sich unten an einem Steg 34 des Rohres 3 abstützt. Der Steg 34 bildet sich durch die Einarbeitung einer nach oben hin offenen Grube 36 in den Rohrkörper 2. Die Druckfedern 32 haben die Aufgabe die über das Schneid- oder Perforiermesser 18 eingeleiteten Schnittkräfte aufzunehmen. In der Keilträgerstange 28 ist entlang ihrer Längsachse in Gewindebohrungen eine Mehrzahl von Innen- und Außengewinde aufweisenden Stehbolzen 37 eingeschraubt. Die Stehbolzen 37 führen durch Bohrungen im Steg 34. Auf jeweils einer oberen Stirnfläche der Stehbolzen 37 aufliegend ist eine Stützschiene 38 (Fig. 6) an ihnen angeschraubt. Die Länge der Stehbolzen ist dabei so gewählt, daß zwischen einer Unterseite der Stützschiene 38 und einer Oberseite 39 (= Grundfläche) der Grube 36 ein Zwischenraum entsteht, so daß die radiale Bewegung des Schneid- oder Perforiermessers 18 nicht beeinträchtigt wird.A wedge support rod 28 (FIG. 5) is arranged between an
Auf der Stützschiene 38 ist eine Messerträgerschiene 41 in Querrichtung der Stützschiene 38 verschiebbar angeordnet. Hierzu ist die Stützschiene 38 mit einer Mehrzahl von nebeneinander angeordneten, sich 90° horizontal zur Längsachse der Stützschiene 38 erstreckender Langlöcher 42 versehen. Die Langlöcher 42 sind jeweils in einem durch eine Nut 43 geschwächten Teil der Stützschiene 38 angeordnet.On the
Die Messerträgerschiene 41 wird an die Stützschiene 38 angeschraubt, indem jeweils eine Schraube 46 mit Paßschaft und auf ihm aufgefädelter Tellerfeder 44 durch das Langloch 42 hindurch in ein Gewindeloch soweit hineingeschraubt wird, bis die notwendige Flächenpressung zwischen Messerträgerschiene 41 und Stützschiene 38 erreicht ist.The
Wird nun die Keilstange 24 nach links oder rechts verschoben (Fig. 1), so senken oder heben sich stufenlos über die schiefen Ebenen der Keilpaarungen 26, 29 die Keilträgerstange 28, die mit ihr formschlüssig verbundene Stützschiene 38 und damit über die Messerträgerschiene 41 auch das Schneid- bzw. Perforiermesser 18.If the
Zusätzlich zur radialen Bewegung oder ohne radiale Bewegung soll das Schneid- bzw. Perforiermesser 18 auch in Umfangsrichtung des Messerzylinders 1, - d. h. in einem Winkel von 90° zum Radius in Umfangsrichtung des Messerzylinders 1 - um eine gewisse Strecke verschoben werden. Dieses ist besonders vorteilhaft um z. B. bei Verwendung von Perforiermessern 18 die Perforationslinie exakt auf die Falzlinie auszurichten oder bei Anordnung von mehreren Schneidmessern 18 auf dem Umfang des Messerzylinders 1, um "kurze" oder "lange" Papierbogen zu schneiden.In addition to the radial movement or without radial movement, the cutting or perforating
In die linke Wand 47 (Fig. 2, Fig. 3) der Grube 36 ist eine Längsnut 48 eingefräst. In dieser Längsnut 48 ist eine Stellstange 49, die eine Mehrzahl von Stellkeilen 51 aufweist, verschiebbar gelagert. Zur Einleitung einer Verschiebekraft ist die Stellstange 49 z. B. an ihrem linken Ende mit einem Koppelstück 52 versehen. Dieses Koppelstück 52 hat ein Innengewinde. An das Koppelstück 52 kann ein hin- und herbewegbares Maschinenelement z. B. ein Ende eines Hebelarmes eines zweiarmigen Hebels, der über eine Rolle, die von einer Nut einer motorisch verdrehbaren Kurvenscheibe bewegt wird, angekuppelt sein. Hierdurch ist die Lage der Stellstange 49 stufenlos veränderbar.A
In die Grube 36 hineinragend sind an der Messerträgerschiene 41 mehrere Gegenkeilstücke 53 angeschraubt und verstiftet (Fig. 2). Aus Vereinfachungsgründen ist in Fig. 2 nur ein einziges dargestellt. Die Keilflächen der Stellkeile 51 und der Gegenkeilstücke 53 gleiten aufeinander. Eine Rückseite 54 der Messerträgerschiene 41 weist eine Mehrzahl von Sacklöchern 56 auf, in die jeweils eine Druckfeder 57 hineingeschoben wird. Die Druckfedern 57 stützen sich jeweils am Boden der Sacklöcher 56 und an Zentrierstücken 58 ab, die an einer rechten Wand 59 der Grube 36 befestigt sind. Wird nun die Stellstange 49 in die Grube 36 hineingeschoben, so drücken die Stellkeile 51 über die Gegenkeilstücke 53 die Messertragerschiene 41 mit dem an ihr befestigten Schneid- oder Perforiermesser 18 gegen die Federkraft der Druckfedern 57 in Richtung auf die rechte Grubenwand 59. Wird die Stellstange 49 nach links in Richtung Grubenende bewegt, so drücken die Druckfedern 57 die Messerträgerschiene 41 mit dem Schneid- oder Perforiermesser 18 von der rechten Grubenwand 59 weg in Richtung auf die linke Grubenwand 47.Protruding into the
