Description

Die Erfindung betrifft ein Maschinenmesser zum Beschneiden von Büchern o. dgl. gemäß dem Oberbegriff von Anspruch 1.The invention relates to a machine knife for trimming books o. Like. According to the preamble of claim 1.

Es ist bekannt, Klingen oder Schneiden aus gehärtetem Stahl oder Hartmetall auf den metallenen Messerträger aufzulöten und beide Teile so fest, d. h. unlösbar miteinander zu verbinden. Verwendung finden derartige Messer vor allem in sogenannten 3-Messer-Automaten und Planschneidemaschinen der Druckindustrie.It is known to cut or cut hardened steel or solder hard metal to the metal knife carrier and both parts so firm d. H. inextricably linked. Find use such knives especially in so-called 3-knife machines and Face cutting machines of the printing industry.

Solche Messer sind mehrfach verwendbar, weil sie mehrfach nachgeschliffen werden können. Dabei verkürzen sie sich und müssen jeweils neu justiert werden. An das Nachschleifen und Justieren sind besondere Anforderungen hinsichtlich Güte, Genauigkeit etc. zu stellen, damit nachfolgend die für die Erzielung der gewünschten Qualität und Effizienz maßgeblichen Prozeßparameter gesichert bleiben. Such knives can be used multiple times because they are multiple can be reground. They shorten and have to be adjusted each time. The regrinding and adjustment are to make special demands regarding quality, accuracy etc. hence the following for achieving the desired quality and Efficient process parameters remain secured.

Die notwendige Bearbeitung der Messer erfolgt in der Regel nicht beim ursprünglichen Hersteller, sondern in lokalen Service-Betrieben, die nach eigenen Bearbeitungsmethoden vorgehen. Zwangsläufig kommt es so zu deutlichen Qualitätseinbußen. Im schlimmsten Falle kann es zu Prozeßstörungen kommen. Außerdem bleibt das Nachschleifen auf bestimmte metallische Werkstoffe mit bestimmten metallurgischen oder chemischen Zusammensetzungen beschränkt.The necessary processing of the knives is usually not done at original manufacturer, but in local service companies, according to use your own processing methods. This is inevitably the case significant loss of quality. In the worst case it can be too Process disruptions are coming. The regrinding also remains on certain metallic materials with certain metallurgical or limited chemical compositions.

AT-U-02658 offenbart ein Messer gemäß Oberbegriff des Anspruchs 1.AT-U-02658 discloses a knife according to the preamble of claim 1.

Hier setzt nun die Erfindung an. Sie hat sich die Aufgabe gestellt, ein neues Maschinenmesser vorzuschlagen, welches kostengünstig in der Herstellung und einfach in der Handhabung ist und eine hohe Prozeßsicherheit gewährleistet.This is where the invention begins. It has set itself the task of creating a new one Propose machine knives, which is inexpensive to manufacture and is easy to use and high process reliability guaranteed.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1. Zweckmäßige Weiterbildungen sind in den nachfolgenden Unteransprüchen angegeben.This object is achieved with the features of claim 1. Appropriate further training are in the following subclaims specified.

Wie ersichtlich, umfaßt das erfindungsgemäße Maschinenmesser im wesentlichen zwei Teile, nämlich einen Messerträger sowie einen daran anbringbaren und davon wieder lösbaren Klingenhalter mit der Klinge oder Schneide. Letztere ist unlösbar mit dem Klingenhalter verbunden.As can be seen, the machine knife according to the invention comprises essentially two parts, namely a knife holder and one on it attachable and detachable blade holder with the blade or Cutting. The latter is permanently connected to the blade holder.

Der Messerträger unterliegt jetzt keinem Verschleiß mehr und ist unveränderlicher Bestandteil der jeweiligen Maschine. Ggfs. dient eine besondere Aussparung o. dgl. der formschlüssigen Aufnahme des neuen Verschleißteils, nämlich des genannten Klingenhalters und der damit verbundenen Klinge.The knife holder is no longer subject to wear and is unchangeable part of the respective machine. If necessary. serves one Special recess or the like. The positive reception of the new Wear part, namely the blade holder mentioned and thus connected blade.

Die Klinge besteht grundsätzlich aus hoch verschleißfestem Material, wie speziellen metallischen Werkstoffen. Die Erfindung erlaubt und begünstigt auch den Einsatz von anderen Materialien, insbesondere Keramik. Im einfachsten Falle kann das Material unbeschichtet zur Anwendung kommen, erlauben große Betriebssicherheit und lange Standzeiten, wobei die Leistungsfähigkeit der Maschinen optimal ausgenutzt werden kann.The blade basically consists of highly wear-resistant material, such as special metallic materials. The invention allows and favors also the use of other materials, especially ceramics. in the in the simplest case, the material can be used uncoated, allow great operational reliability and long service life, the Performance of the machines can be optimally used.

Der Verschleiß reduziert sich also jetzt auf den Klingenhalter samt Klinge. Es handelt sich insoweit um ein verhältnismäßig preiswert herstellbares Verschleißteil, für das sich ein Nachschleifen nicht mehr lohnt. Dieses ist einfach und paßgenau auszuwechseln. Damit entfallen die eingangs genannten Nachteile, insbesondere Prozeßunsicherheiten.Wear is now reduced to the blade holder and blade. It To this extent it is a relatively inexpensive to manufacture Wear part for which regrinding is no longer worthwhile. This is easy to replace. This eliminates the entry mentioned disadvantages, in particular process uncertainties.

Nach den Fig. 1 bis 3 ist ein bandförmiger bzw. in Draufsicht rechteckiger Messerträger 1 aus Metall mit mehreren Bohrungen 2 versehen, um ihn an einer - hier nicht näher dargestellten - Maschine fixieren, d. h. anbringen zu können. An seiner im montierten Zustand freistehenden Längsseite verfügt der Messerträger 1 über eine falzförmige Aussparung 3, in die ein leistenförmiger Klingenhalter 4 mit trapezförmigem Querschnitt flächenbündig eingesetzt und mit Schrauben - welche hier aus Gründen einer besseren Übersicht nicht dargestellt sind - am Messerträger 1 gesichert ist. Zu sehen sind dagegen eine Gewindebohrung 5 im Messerträger 1 und eine damit fluchtende Durchsteckbohrung 6 im Klingenhalter 4, welche eingangs zylinderförmig erweitert ist, so daß eine Schraube flächenbündig in den Klingenhalter 4 versenkbar ist.1 to 3 is a band-shaped or rectangular in plan view Knife holder 1 made of metal with several holes 2 to it fix a machine - not shown here - d. H. attach to can. Has its free-standing long side when assembled the knife carrier 1 via a rabbet-shaped recess 3 into which a strip-shaped blade holder 4 with a trapezoidal cross-section used flush and with screws - which here for reasons a better overview are not shown - secured on the knife holder 1 is. On the other hand, a threaded bore 5 can be seen in the knife carrier 1 and an aligned through hole 6 in the blade holder 4, which is expanded cylindrical at the beginning, so that a screw is flush in the blade holder 4 is retractable.

Wie weiter aus den Figuren hervorgeht, stehen die Begrenzungsflächen der Aussparung 3 am innenliegenden Ende ebenso wie die damit zusammenwirkenden Begrenzungsflächen des Klingenhalters 4 unter einem spitzen Winkel zueinander, d. h. einem Winkel von weniger als 90°. Dadurch wird ein hoher Formschluß im Interesse einer gleichmäßigen und sicheren Kraftübertragung sowie langer Standzeiten (Lebensdauer) ermöglicht. Es ist sozusagen ein Zwangssitz gebildet, in den der Klingenhalter 4 unter Belastung gepreßt wird und worin er dann besonders sicher gehalten ist.As can further be seen from the figures, the boundary surfaces of the Recess 3 at the inner end as well as the one with it cooperating boundary surfaces of the blade holder 4 under one acute angles to each other, d. H. an angle of less than 90 °. Thereby is a high form fit in the interest of an even and safe Power transmission and long service life (service life) enables. It is a forced seat, so to speak, into which the blade holder 4 below Load is pressed and in which it is then held particularly securely.

Der Klingenhalter 4 besteht aus Metall. Sein freies Ende, d. h. hier seine freistehende Längsseite ist mit einer Klinge 7 aus einem besonders verschleißfesten Werkstoff besetzt. Dabei handelt es sich um ein Hartmetall mit einer Diamantbeschichtung, d. h. mit einem Überzug aus Diamantsplittern. Die Klinge 7 ist ihrerseits in einen Falz 8 am Klingenhalter 4 eingesetzt und darin unlösbar verklebt. Für die Klinge 7 gilt in Bezug auf den Klingenhalter 4 mit seinem Falz 8 ähnliches wie für den Klingenhalter 4 in Bezug auf den Messerträger 1 mit seiner falzförmigen Aussparung 3. Auch bei der Klinge 7 sorgen unter spitzem Winkel zueinander stehende Begrenzungsflächen für eine gute Abstützung und sicheren Halt im Falz 8 mit seinen entsprechenden Begrenzungsflächen, wobei Klingenhalter 4 und Klinge 7, wie bereits gesagt, unlösbar miteinander verbunden sind und sozusagen ein einstückiges Verschleißteil bilden. Dieses ist kostengünstig herzustellen, bequem zu handhaben, insbesondere einfach und sicher zu positionieren und im übrigen zuverlässig im Gebrauch.The blade holder 4 is made of metal. Its free end, d. H. here its freestanding long side is special with a blade 7 wear-resistant material occupied. It is a hard metal with a diamond coating, d. H. with a coating Diamond chips. The blade 7 is in turn in a fold 8 on the blade holder 4 used and glued in there permanently. For blade 7 applies with respect to the blade holder 4 with its fold 8 similar to that for the blade holder 4 in relation to the knife carrier 1 with its rebate-shaped recess 3. Also the blade 7 ensures that they are at an acute angle to one another Boundary surfaces for good support and a secure hold in the fold 8 with its corresponding boundary surfaces, with blade holder 4 and Blade 7, as already said, are inextricably linked and form a one-piece wear part, so to speak. This is inexpensive to manufacture, easy to handle, in particular simple and safe to position and otherwise reliable in use.

Für eine etwas andere Ausführungsform gemäß den Fig. 4 bis 7 gelten grundsätzlich dieselben Betrachtungen. Der Messerträger 1' hat hierbei in Draufsicht eine etwas andere Form, ist aber im übrigen auch wieder bandförmig ausgebildet. Ein bemerkenswerter Unterschied liegt jedoch darin, daß der Klingenhalter 4' an seinem freien Ende über eine Nut 9 verfügt, welche zur Oberfläche des Klingenhalters 4' leicht schräg verläuft. In diese Nut 9 ist eine Klinge 10 eingelassen. Dank des besonderen Haltes und Schutzes, den die Nut 9 der Klinge 10 verleiht, kann hier auch Material für die Klinge 10 gewählt werden, welches ansonsten wegen seiner Stoßempfindlichkeit o. ä. ausscheidet. So ist denn die Klinge 10 aus keramischem Material gewählt, welches über eine hohe Schneidqualität verfügt. Auch für diese Ausführungsform gilt, daß Klinge 10 und Klingenhalter 4' unlösbar miteinander verbunden sind und so ein einstückiges Verschleißteil bilden.For a somewhat different embodiment according to FIGS. 4 to 7 apply basically the same considerations. The knife carrier 1 'has in Top view is a slightly different shape, but is also again band-shaped. However, one notable difference is that the blade holder 4 'has a groove 9 at its free end, which is slightly oblique to the surface of the blade holder 4 '. In these A blade 10 is embedded in groove 9. Thanks to the special hold and Protection that the groove 9 gives the blade 10 can also material for the blade 10 are chosen, which is otherwise because of its Shock sensitivity or the like is eliminated. So the blade 10 is out ceramic material selected, which has a high cutting quality features. Also for this embodiment, blade 10 and Blade holder 4 'are non-detachably connected and so one form one-piece wear part.

Bei einer weiteren Ausführungsform eines erfindungsgemäßen Maschinenmessers gemäß Fig. 8 ist vorgesehen, daß der Klingenhalter 4" an der Messerspitze derart gegenüber dem Messerträger 1" zurückspringt und ausgeformt ist, daß die Klinge 11 den Klingenhalter 4" in voller Höhe überdeckt und eine zur Abstützung gegenüber der Aussparung 3 dienende Berührungsfläche 13 bildet. Dabei ist die Klinge 11 noch sicherer gehalten als zuvor, so daß sie auch einer stärkeren Beanspruchung standhält. Dies ist von Bedeutung, wenn Kräfte nicht allein in Richtung der ausgezogenen Pfeillinie P sondern auch in Richtung der gestrichelten Pfeillinie auf die Messerspitze wirken. Dann nämlich können solche Kräfte zum Teil über die erwähnte Berührungsfläche 13 auf den Messerträger 1" abgeleitet und gewissermaßen neutralisiert werden.In a further embodiment of an inventive 8 is provided that the blade holder 4 " jumps back at the knife tip in relation to the knife carrier 1 " and is shaped that the blade 11 the blade holder 4 "in full height covered and one serving to support the recess 3 Touch surface 13 forms. The blade 11 is held even more securely than before, so that it can withstand more stress. This is important when forces are not alone in the direction of the extended Arrow line P but also in the direction of the dashed arrow line on the Knife tip work. Then such forces can be partly via the mentioned contact surface 13 derived on the knife carrier 1 "and be neutralized to a certain extent.

Verstärkt werden kann dieser Effekt noch dadurch, daß an der Klinge 12 gemäß Fig. 9 ein Verlängerungsabschnitt 14 vorgesehen ist. Dieser kann in Bezug auf den Klingenhalter 4''' abgestuft sein, ebenso gut aber auch eine andere Form aufweisen. This effect can be reinforced by the fact that on the blade 12 9, an extension section 14 is provided. This can be in Regarding the blade holder 4 '' 'be graded, but equally good have a different shape.
