Description

Abschneidevorrichtung für Papier od. dgl. In der Technik werden für die verschiedensten Zwecke Abschneidevorrichtungen verwendet, die entweder scheren- oder messerartig ausgebildet sind. Für leichte Schneidarbeiten wird dabei im allgemeinen die scherenartige Ausbildung der Abschrfeidevorrichtungen bevorzugt, während für schwerere Schrteidarbeiten vorzugsweise Vorrichtungen verwendet werden, bei welchen die Messer bzw. Schneidkanten parallel gegeneinander bewegt werden. Die Parallelbewegung der Messer bedingt jedoch eine genaue Geradführung der Messer, die einen relativ hohen konstruktiven bzw. mechanischen Aufwand erfordert und derartige Abschneidevorrichtungen verteuert.Cutting device for paper or the like. In the art for used cutting devices for the most varied of purposes, which are either shear- or are designed like a knife. This is generally used for light cutting work the scissors-like design of Abschrfeidevorrichtungen while for heavier cutting jobs are preferably used with devices in which the knives or cutting edges are moved parallel to each other. The parallel movement However, the knife requires a precise straight line guidance of the knife, which is a relative requires high structural and mechanical effort and such cutting devices expensive.

Die vorliegende Erfindung schlägt nun eine Lagerung und Geradführung für die Messer solcher Abschneidevorrichtungen vor, die besonders einfach, billig und wirksam ist. Der Erfindung gemäß werden die Messer oder eines derselben von zwei oder mehr, einerseits fest gelagerten, parallel zueinander beweglichen, starr oder nachgiebig ausgebildeten Gliedern .öder Gruppen solcher Glieder getragen, deren freie Enden in gleichem, dem Lagerbestand entsprechendem Abstand voneinander parallelogrammartig ge-, haltert sind. Hierbei können die das oder die Messer tragenden Glieder Teile eines starren Gelenkparallelogramms bilden, von denen zwei Gelenkpunkte fest und zwei beweglich angeordnet sind. Die die Messer tragenden Glieder können aber auch in der Bewegungsrichtung federnd nachgiebig, insbesondere als Blattfedern, ausgebildet werden, die einerseits fest gelagert und deren freie bewegliche Enden starr in der festen Lagerung entsprechenden Abständen gehaltert sind. Die Messer sind also gernäß der Erfindung an dem bewe glichen Teil einer-Art von Gelenkparallelogramm angeordnet, dessen eine Seite in an sich bekannter Weise fest gelagert ist, wobei die Gelenkpunkte auch durch in der Bewegungsrichtung nachgiebig federnd ausgebildete, an ihren Enden starr gehalterte Federn, insbesondere Blattfedern ersetzt werden können.The present invention now proposes storage and straight guidance for the knives of such cutting devices, which are particularly simple, cheap and is effective. According to the invention, the knife or one of the same are from two or more, on the one hand fixedly mounted, movable parallel to one another, rigid or resilient members. or groups of such members, their Free ends at the same distance from each other, corresponding to the stock, in the manner of a parallelogram are held. Here, the members carrying the knife or knives can be parts form a rigid joint parallelogram, of which two points of articulation are fixed and two are movably arranged. The members carrying the knife can also resiliently resilient in the direction of movement, in particular as leaf springs are, on the one hand, firmly mounted and their free movable ends rigid in the fixed storage are kept at appropriate distances. The knife are therefore like according to the invention on the movable part of a type of joint parallelogram arranged, one side of which is fixedly mounted in a manner known per se, wherein the articulation points also by resiliently designed to be resilient in the direction of movement, springs rigidly held at their ends, in particular leaf springs, are replaced can.

Die Bewegung kann dabei dem Vorschlage der Erfindung gemäß durch Exzenterscheiben erfolgen, an denen das Gelenkparallelogramm federnd anliegt, so daß durch Drehung der Exzenter eine zwangsläufige Hin- und Herbewegung der Messer bei sehr genauer Geradführung erreicht wird. In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungs-"egenstandes beispielsweise dargestellt, und zwar zeigt Abb. 1 > eine Messerführung mittels eine" starren Gelenkparallelogramms; Abb. 2 nnd 3 zeigen eine Parallelführung eines Messers mittels einer federnd nachgiebigen Parallelführung.The movement can be carried out according to the proposal of the invention by eccentric disks on which the joint parallelogram rests resiliently, so that by rotating the eccentric an inevitable back and forth movement of the knife is achieved with very precise straight line guidance. In the drawing, two exemplary embodiments of the subject matter of the invention are shown, for example, namely, Fig. 1 shows a knife guide by means of a rigid joint parallelogram; Fig. 2 and 3 show a parallel guide of a knife by means of a resilient parallel guide.

Gemäß Abb i gleitet an dem oberen feststehenden Messer i ein bewegliches Messer 2 schneidend entlang, wobei das Schneidgut 3 abgetrennt wird. Das fest-.stehende Messer i ruht hierbei auf zwei Säulen. An einer dersblben siA zwei starre Arme 7 in bestimmtem Abstand voneinander angelenkt, deren freie Enden in dem gleichen Abstand durch das starre Glied 5 gehalten werden, mit dem sie ebenfalls gelenkig verbunden sind. Das starre Glied 5 dient gleichzeitig als Träger des Messers 2. Unterhalb des Messerträgers 5 und an diesem anliegend ist eine Exzenterscheibe 4 angeordnet, die bei Drehung eine Auf- und Abwärtsbewegung des Gelenkparallelogramms des Messerträgers 5 und damit des Messers 2 bewirkt. Da die Arme 7 zusammen mit dem Messerträger 5 eine parallelogrammartig wirkende Geradführung bilden, bewegt sich das Messer i. Die Anlage des Messerträgers 5 an der Exzenterscheibe 4 kann dabei durch das Eigengewicht des Messers und des Gelenkparallelogramms erfolgen, kann aber auch durch Federn bewirkt oder unterstützt werden.According to Fig. I, a movable knife 2 slides along the upper fixed knife i in a cutting manner, the material to be cut 3 being separated. The fixed knife i rests on two pillars. On one of these two rigid arms 7 are articulated at a certain distance from one another, the free ends of which are held at the same distance by the rigid member 5 , with which they are also articulated. The rigid member 5 also serves as a carrier for the knife 2. Below and adjacent to the knife carrier 5 is an eccentric disk 4 which, when rotated, causes the articulated parallelogram of the knife carrier 5 and thus the knife 2 to move up and down. Since the arms 7 together with the knife carrier 5 form a straight-line guide that acts like a parallelogram, the knife i moves. The contact of the knife carrier 5 on the eccentric disk 4 can take place by the dead weight of the knife and the joint parallelogram, but can also be brought about or supported by springs.

In der Abb. 2 sind an Stelle der starren Glieder der Parallelführung 7 Doppelblattfedern verwendet, die keine drehbare Lagerung erfordern und genau denselben Zweck erfüllen. Dieses Federnpaar 7" ist einerseits am Messerhalter 5 und andererseits am Befestigungsklotz 6 'starr befestigt. Diese Art der Parallelführung macht außerdem durch die dem Federnpaiir 7a innewohnende Federkraft eine eigene Rückholfeder entbehrlich.In Fig. 2, instead of the rigid members of the parallel guide 7 double leaf springs are used, which do not require a rotatable bearing and serve exactly the same purpose. This pair of springs 7 ″ is rigidly fastened on the one hand to the knife holder 5 and on the other hand to the fastening block 6 '. This type of parallel guidance also makes a separate return spring unnecessary due to the spring force inherent in the spring pair 7a.

Abb. 3 zeigt die Verformung der Federn während des Schneidevorganges und die Befestigung der Federn im Profil. Die neue Schneidevorrichtung kann für die verschiedensten Anwendungsgebiete herangezogen werden, wo immer messer- oder scherenhafte Abtrennung erforderlich ist, so z. B. an Verpackungsmaschinen, in photographischen 'Kameras usw.Fig. 3 shows the deformation of the springs during the cutting process and the fastening of the springs in the profile. The new cutting device can be used for a wide variety of applications, wherever knife- or scissors-like separation is required, such. B. on packaging machines, in photographic cameras, etc.
