Description

Es sind bereits Papierschneidemaschinen bekannt, bei denen eine Messerhalterung zum gleichzeitigen Beschneiden dreier Seiten, insbesondere von Zeitschriften, vorgesehen ist, wobei die in unterschiedlicher Richtung verlaufenden Messerschneiden übereinander gestaffelt angeordnet sind.There are already paper cutting machines known in which a knife holder for simultaneous Trimming of three pages, in particular of magazines, is provided, with those in different Direction running knife edges are staggered one above the other.

Erfindungsgemäß weisen nun die parallel zueinander verlaufenden Messer an ihren dem Rücken des Schneidgutes gegenüberliegenden Enden oberhalb ihrer Schneidkanten je eine Aussparung zur Aufnähme des quer zu den parallelen Messern verlaufenden Messers auf, wobei für sämtliche Messer Gegenmesser vorgesehen sind. Das hat gegenüber den bekannten Papierschneidemaschinen den Vorteil, daß der Hub des Schneidkopfes, an dem die Messer sitzen, kleiner ausgeführt werden kann, so daß eine bedeutend höhere Hubzahl und damit mehr Schnitte je Zeiteinheit möglich sind.According to the invention now have the parallel blades on their back of the Material to be cut opposite ends above their cutting edges each have a recess for receiving of the knife running transversely to the parallel knives, with counter knives for all knives are provided. This has the advantage over the known paper cutting machines that the stroke of the cutting head, on which the knives sit, can be made smaller, so that a significantly higher number of strokes and thus more cuts per unit of time are possible.

2 a rechtwinklig zum Längsverlauf der Anlage 6 a und die Messer 3, 3 a parallel zur Anlage 6 a. Zum Beschneiden von Papierlagen verschiedenen Formates sind verschiedene Schneidköpfe 4 und Tische 6, an denen die Gegenmesser la, 2a, 3a festgeschraubt sind, notwendig. 2 a at right angles to the longitudinal course of the system 6 a and the knives 3, 3 a parallel to the system 6 a. For trimming paper sheets different format are different cutting heads 4 and Tables 6 to which the counter blade la, 2a are screwed, 3a, necessary.

Die beweglichen Obermesser 1, 2 und 3 bzw. der Schneidkopf 4 besitzen einen gemeinsamen Antrieb. Hierzu ist der Schneidkopf 4 über einen an ihm angelenkten Lenker 7, einen um eine ortsfeste Achse 8 im Gestell 5 schwenkbaren Zweiarmhebel 9 und eine darin angelenkte Kurbelstange 10 mit Kurbelrad II durch Übertragungsorgane 12 mit dem Antriebsmotor 13 verbunden. Durch die genannten Organe 7 bis 11 wird die Drehbewegung des Antriebsmotors 13 in eine Auf- und Abbewegung des Schneidkopfes 4 mit den Messern 1, 2 und 3 umgewandelt.The movable upper knives 1, 2 and 3 or the cutting head 4 have a common drive. For this purpose, the cutting head 4 is via a link 7 articulated to it, one around a stationary axis 8 Two-arm lever 9 pivotable in the frame 5 and a connecting rod 10 with crank wheel II articulated therein connected to the drive motor 13 by transmission members 12. By the above-mentioned bodies 7 to 11, the rotary movement of the drive motor 13 is converted into an up and down movement of the cutting head 4 converted with knives 1, 2 and 3.

Alle drei Obermesser 1, 2 und 3 sind länger ais das vorgesehene Schneidformat. Dadurch ist es möglich, einen sauberen Schnitt an den beiden Schnittecken zu erzielen.All three top knives 1, 2 and 3 are longer than the intended cutting format. This makes it possible to achieve a clean cut at the two cut corners.

Die beiden rechtwinklig zum Anschlag 6 a bzw. zum Rücken des Schneidgutes liegenden Messer 1, 2 weisen an den Schnittecken oberhalb ihrer Schneidkanten je eine Aussparung 1 b, 2 b zur Aufnahme des Messers 3 auf. Dieses bzw. dessen Schneidkante liegt daher höher als die Schneidkanten der anderen beiden Messerschneiden 1, 2. Der Schneidvorgang beginnt somit mit dem Einsatz der beiden parallel zueinander liegenden Messer 1, 2, deren SchnittwegThe two knives 1, 2 lying at right angles to the stop 6 a and to the back of the material to be cut each have a recess 1 b, 2 b for receiving the knife 3 at the cut corners above their cutting edges. This or its cutting edge is therefore higher than the cutting edges of the other two knife edges 1, 2. The cutting process thus begins with the use of the two parallel knives 1, 2, their cutting path

mindestens so tief gehen muß, bis das zeitlich etwas nach den Messern 1, 2 zur Wirkung kommende, parallel zum Rücken liegende Messer 3 das Schnittgut ebenfalls vollständig geschnitten hat.must go at least as deeply as the time after knives 1, 2 comes into effect, Knife 3 lying parallel to the back has also completely cut the material to be cut.

Die Obermesser 1, 2 und 3 sind zu den Untermessern Ια, 2α und 3α nach dem Prinzip von Scherenmessern angeordnet, d. h., die Schneidkanten der Obermesser 1, 2 und 3 sind in ihrer Längserstreckung nicht parallel zu den Schneidkanten der Untermesseria, 2a und 3a, sondern im spitzen Winkel angeordnet, wie dies aus den Fig. 3 und 4 ersichtlich ist.The upper knives 1, 2 and 3 are to the lower knives Ια, 2α and 3α according to the principle of Scissor knives arranged, d. That is, the cutting edges of the upper knives 1, 2 and 3 are in their longitudinal extension not parallel to the cutting edges of the lower knife, 2a and 3a, but in the pointed Arranged angle, as shown in FIGS. 3 and 4 can be seen.

Zur Erzielung einer genauen Schnittführung und eines sauberen Schnittes dienen die nachstehend beschriebenen Maßnahmen:The following are used to achieve a precise cut and a clean cut Measures:

Die Obermesser 1,2 und 3 sitzen je an einem Halter 15, der um eine Achse 16 quer zur Ebene des Messers schwenkbar gelagert ist. Die Messer 1, 2 und 3 sind mittels Schrauben 21 an den Haltern starr, aber lösbar befestigt (Fig. 8). Je Halter 15 sind neben den Befestigungsschrauben 21, über die Länge des Halters verteilt, mehrere Schraubenbolzen 17 vorgesehen, die den Halter 15 und das Messer 1 bzw. 2 bzw. 3 durchsetzen und im Schneidkopf 4 ein- und ausschraubbar sind. An ihrem freien Ende besitzen die Bolzen 17 ein Gewinde mit Mutter 17 a. Die die Bolzen 17 umgebenden Federn 14 stützen sich einerseits gegen die Muttern 17 a und andererseits gegen die Messer ab. Die Halter 15 lassen sich demzufolge nur mit den Messern zusammen um die Achse 16 bewegen, wobei der Halter bzw. das Messer unter dem durch die Mutter 17 a verstellbaren Druck der Feder 14 steht.The upper knives 1, 2 and 3 are each seated on a holder 15 which is transverse to the plane of the knife about an axis 16 is pivotably mounted. The knives 1, 2 and 3 are rigid by means of screws 21 on the holders, but releasably attached (Fig. 8). Each holder 15 is next to the fastening screws 21, over the length of the holder distributed, a plurality of screw bolts 17 are provided, which the holder 15 and the knife 1 or 2 or 3 enforce and can be screwed in and out in the cutting head 4. At their free end they own Bolt 17 a thread with nut 17 a. The springs 14 surrounding the bolts 17 are supported on the one hand against the nuts 17 a and on the other hand against the knife. The holder 15 can therefore only move with the knives together around the axis 16, the holder or the knife under the through the nut 17 a adjustable pressure of the spring 14 is.

In Ruhestellung befinden sich die Messer in der in Fig. 8 gezeigten Lage, in der die Halter 15 und die Messer über die Stellschrauben 22 durch die Feder 14 am Schneidkopf 4 anliegen. Beim Schnittvorgang werden die Messer durch die Federn 14 an die Gegenmesser angedrückt in einer Stellung, in der die Stellschrauben 22 zum Schneidkopf 4 etwas Spiel haben.In the rest position, the knives are in the position shown in Fig. 8, in which the holder 15 and the The knife rest against the cutting head 4 via the adjusting screws 22 through the spring 14. During the cutting process the knives are pressed against the counter knife by the springs 14 in a position in which the Adjusting screws 22 for cutting head 4 have some play.

Ferner sind innerhalb des durch die Messerpaare 1, la, 2, 2a, 3 und 3a gebildeten Rahmenstückes Leisten 18 vorgesehen (Fig. 5 und 6), die vor Schneidbeginn bis nach erfolgtem Schnitt das Schneidgut von oben auf seine Unterlage drücken. Hiermit wird ein Planliegen des Schneidgutes gewährleistet und ein Verschieben desselben ausgeschlossen. Die Leisten 18 sind an Stiften 19 befestigt, die im Schneidkopf 4 verschiebbar gelagert sind und unter dem Einfluß von Federn 20 stehen, die bestrebt sind, die Leisten 18 aus dem Schneidkopf herauszudrücken, so daß sie in Ruhelage des Schneidkopfes gegenüber den Schneidkanten der beweglichen Obermesser 1, 2 und 3 nach unten vorstehen (Fig. 1 und 5). Beim Arbeitshub des Schneidkopfes 4 gelangen somit zunächst die Leisten 18 zur Einwirkung auf das Schneidgut und halten es für den Schneidvorgang fest. Nach Beendigung des Schneidvorganges gehen zunächst die Messer 1, 2 und 3 zurück, und erst dann verlassen die Leisten 18 das Schneidgut.Furthermore, strips are within the frame piece formed by the pairs of knives 1, la, 2, 2a, 3 and 3a 18 is provided (Fig. 5 and 6), which before the start of cutting until after the cut has been made, the material to be cut from press on top of its pad. This ensures that the food to be cut is flat and that it is Moving the same excluded. The strips 18 are attached to pins 19 which are located in the cutting head 4 are slidably mounted and are under the influence of springs 20 which strive to the strips 18 to push out of the cutting head so that they are in the rest position of the cutting head opposite the cutting edges the movable upper knife 1, 2 and 3 protrude downwards (Fig. 1 and 5). With the working stroke of the Cutting head 4 thus first reach the strips 18 to act on the material to be cut and hold it for the cutting process. After the end of the cutting process, knives 1, 2 go first and 3 back, and only then do the strips 18 leave the material to be cut.

Durch die vorliegende Erfindung ist es möglich, die Bauart solcher Schneidemaschinen sehr zu vereinfachen und den dafür erforderlichen Platz bedeutend zu reduzieren sowie die vorerwähnten Nachteile der bis anhin bekannten Schneidvorrichtung zu beheben.The present invention makes it possible to greatly simplify the construction of such cutting machines and to significantly reduce the space required for this, as well as the aforementioned disadvantages to fix the previously known cutting device.
