Die Erfindung betrifft eine Vorrichtung zum Schneiden von flächigen Bogen oder Bahnen aus Papier oder Kunststoff, bestehend aus einem einer Auflage für das Schnittgut zugeordneten ersten Messerteil und einem senkrecht zur Auflage mit dem ersten Messerteil zusammenwirkenden zweiten Messerteil, der gegenüber dem ersten Messerteil eine mit Anzug ausgebildete Schneidkante aufweist.The invention relates to a device for cutting flat Sheets or sheets of paper or plastic, consisting of from a first edition assigned to the clippings Knife part and one perpendicular to the support with the first knife part interacting second knife part, the opposite the first knife part a cutting edge designed with a suit having.
Schneidvorrichtungen dieser Art werden in der papierverarbeitenden Industrie und ähnlichen Betrieben verwendet. Sie dienen u.a. dem Zuschneiden von gestapelten Papierbogen oder Folien auf eine bestimmte Formatgrösse oder dem Beschneiden von gehefteten oder gebundenen Zeitschriften, Buchblöcken, Broschuren, Katalogen etc.Cutting devices of this type are used in paper processing Industry and similar companies. You serve i.a. the cutting of stacked sheets of paper or foils to a certain format size or trimming stapled or bound magazines, book blocks, brochures, Catalogs etc.
Dabei werden die auf einer horizontalen Unterlage gestapelt
aufeinanderliegenden Blätter einseitig einer hohen Schneidkraft
ausgesetzt, die durch die schräg verlaufende Schnittkante
des beweglichen Messerteils bzw. durch das an der einen
Seitenkante des Blatt- oder Produktestapels angreifende bewegliche
Messerteil eine die Blätter seitlich der Messerkante
abhebende Kraft und eine den oberen Stapelbereich zur seitlichen
Verschiebung der Blätter neigende horizontale Kraftkomponente
auslöst.
Darüberhinaus wird durch diese einseitige Krafteinwirkung eine
entsprechend ungünstige Belastung der Antriebselemente bewirkt.The sheets stacked on top of each other on a horizontal base are subjected to a high cutting force on one side, which is exerted by the obliquely running cutting edge of the movable knife part or by the movable knife part engaging on one side edge of the sheet or product stack, and a force lifting the leaves to the side of the knife edge triggers a horizontal force component tending to the upper stack area for lateral displacement of the sheets.
In addition, this one-sided force action causes a correspondingly unfavorable load on the drive elements.
Aufgabe der vorliegenden Erfindung ist es somit, eine Schneidvorrichtung nach der eingangs erwähnten Art zu schaffen, mit welcher die aufgeführten Nachteile weitgehend behoben bzw. mit der bei einer relativ grossen Verarbeitungsleistung eine hohe Schnittqualität erreicht werden kann.The object of the present invention is therefore a cutting device to create in the manner mentioned at the beginning with which largely eliminates the disadvantages listed or with which is high with a relatively high processing power Cutting quality can be achieved.
Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die
Schneidkante des zweiten Messerteils zwei schenkelartige Abschnitte
aufweist, die in Schneidlage einen auf die gegenüberliegende
Schneidkante des ersten Messerteils bzw. auf das
Schneidgut verteilten stumpfen Winkel bilden.
Dadurch kann das zu schneidende Produkt auf bzw. über der Auflage
durch das resp. die angetriebenen Messerteile gleichmässig
beaufschlagt und mit weitgehend regelmässiger Schnittkraft
bearbeitet werden.
Die Verschiebungen werden so unterbunden und die Belastung
kann über das die Messerteile und die beanspruchten Maschinenteile
etwa gleichmässig verteilt werden.
Überdies wird die Schnittzeit und der Hub des/der Messerteile
merkbar verkürzt; die Standzeit der Messerteile wird erhöht- und
die Schnittqualität gegenüber anderen Schneidprinzipien
verbessert. According to the invention, this object is achieved in that the cutting edge of the second knife part has two leg-like sections which, in the cutting position, form an obtuse angle distributed on the opposite cutting edge of the first knife part or on the material to be cut.
This allows the product to be cut on or above the support by the resp. the driven knife parts are evenly applied and machined with largely regular cutting force.
The displacements are prevented and the load can be evenly distributed over the knife parts and the stressed machine parts.
In addition, the cutting time and the stroke of the knife parts are shortened noticeably; The service life of the knife parts is increased and the cutting quality is improved compared to other cutting principles.
Vorteilhaft weist der stumpfe Winkel α eine etwa senkrecht zur Schneidkante des ersten Messerteils verlaufende Winkelhalbierende auf, sodass eine gleichmässige Verteilung der schenkelartigen Abschnitte der Schneidkante des zweiten Messerteils gegenüber der Schneidkante des ersten Messerteils resp. des zu schneidenden Blatt- oder Produktestapels entstehen kann, bei welcher die Schnittkräfte entsprechend günstig verteilt sind.The obtuse angle α advantageously has an approximately perpendicular to Cutting edge of the first knife part running bisector on, so that an even distribution of the leg-like Sections of the cutting edge of the second knife part opposite the cutting edge of the first knife part. of the too cutting sheet or product stacks can arise which the cutting forces are appropriately distributed.
Alternativ können die schenkelartigen Abschnitte ungleichmässig auf die gegenüberliegende Schneidkante des ersten Messerteils verteilt werden, sodass sie in der Schneidlage unterschiedliche spitze Winkel mit der Schneidkante des ersten Messerteils bilden und dementsprechend auch bei zu beschneidendem unregelmässigem Querschnitt eines Druckproduktes oder Stapels optimal eingesetzt werden können, beispielsweise bei Kopf- und/oder Fussbeschnitt.Alternatively, the leg-like sections can be uneven on the opposite cutting edge of the first knife part be distributed so that they differ in the cutting position acute angle with the cutting edge of the first knife part form and accordingly also in the case of to be circumcised irregular cross-section of a printed product or stack can be optimally used, for example in headers and / or Foot trim.
Günstig erweist sich die erfindungsgemässe Vorrichtung für das Beschneiden von einzelnen oder gestapelten mehrblättrigen Druckprodukten, wie Zeitschriften, Broschuren, Buchblöcken, Büchern oder Stapeln loser Blätter bzw. Bogen sowie übereinandergeführten Bahnen in der papierverarbeitenden Industrie.The device according to the invention proves to be favorable for the Pruning single or stacked multi-leaf Printed products, such as magazines, brochures, book blocks, Books or stacks of loose sheets or sheets as well as stacked sheets Pathways in the paper processing industry.
Sodann ist es zweckmässig, wenn der mit dem ersten Messerteil einen kleineren spitzen Winkel bildende schenkelartige Abschnitt der Schneidkante des zweiten Messerteils beim Beschneiden der Kopf- und/oder Fussseite eines Druckproduktes dem bundseitigen Ende zugeordnet ist.Then it is useful if the one with the first knife part a thigh-like section forming a smaller acute angle the cutting edge of the second knife part when trimming the top and / or bottom side of a printed product is assigned to the federal end.
Damit der zweite Messerteil an regelmässige und unregelmässige Querschnitte der Druckprodukte anpassbar ist, ist er bezüglich Lage des stumpfen Winkels verstellbar ausgebildet. So that the second knife part on regular and irregular Cross sections of the print products is customizable, it is regarding The position of the obtuse angle is adjustable.

Die erfindungsgemässe Vorrichtung 1 zum Schneiden von flächigen
Bogen oder Bahnen aus Papier oder Kunststoff resp. Kunststofffolie
gemäss den Fig. 1 und 2 besitzt einen an einem oberen
Messerbalken 2 befestigten beweglichen zweiten Messerteil
3 und einen mit diesem schneidend zusammenwirkenden, an einem
unteren Messerbalken 4 befestigten ersten Messerteil 5. Beide
Messerteile 3, 5 sind in einer unmittelbar anschliessend beginnenden
Schneidlage dargestellt.
Zwischen beiden Messerteilen 3, 5 befindet sich eine geheftete oder
gebundene Zeitschrift 6, die an der nachlaufenden offenen
Seite geschnitten wird. Diese Zeitschrift 6 kann sowohl im
Stillstand als auch während dem Transport bei gleichsinnig
mitlaufenden Messerteilen 3, 5 an Kopf und Fuss sowie an der
offenen Seite beschnitten werden. Die Förderrichtung der Zeitschriften
ist durch F festgehalten. Als Auflage 7 dient ein
der Schneidebene vor- oder nachgeschalteter Tisch oder dgl.
Unterlagen, die mit der Schneidkante 8 des ersten Messerteils
5 eine koplanare Ebene bilden.
Der zweite Messerteil 3 weist eine Schneidkante 9 auf, die aus
zwei Abschnitten 10, 11 gebildet ist, welche einen auf die
gegenüberliegende Schneidkante 8 resp. das Schneidgut bzw. die
Zeitschrift 6 verteilten stumpfen (offenen) Winkel α bilden. The inventive device 1 for cutting flat sheets or sheets of paper or plastic, respectively. 1 and 2 has a movable

Handelt es sich bei dem Schneidgut um einen gleichmässigen
Stapel wie in Fig. 1 gezeigt, dann ist der zweite Messerteil 3
so angeordnet, dass die Winkelhalbierende von α etwa senkrecht
zur Auflage 7 resp. zur Schneidkante 8 des ersten Messerteils
3 oder parallel zur Schneidbewegung eines Messerteils 3, 5
verläuft.
Hinsichtlich der Wirkung der Vorrichtung 1 ist es möglich,
dass wenigstens einer der Messerteile 3, 5 gegen den anderen
Messerteil 5, 3 angetrieben ist oder dass beide Messerteile 3,

10, 11 der Messerkante 9 gleichmässig auf die gegenüberliegende
Schneidkante 8 verteilt sind und mit letzterer jeweils
einen spitzen Schnittwinkel β, γ -von etwa 1 bis 5°- bilden,
wodurch die Schnittkraft auf zwei Seiten etwa gleichmässig
verteilt und eine entsprechend ausgeglichene Belastung entstehen
wird.
Handelt es sich beispielsweise um einen Kopf- oder Fussbeschnitt
eines Druckproduktes oder mehrerer übereinanderliegender
Druckprodukte, dann können die spitzen Schnittwinkel β, γ
ungleich gross gewählt werden, d.h., dass beispielsweise der
Schnittwinkel an der Bundseite, wo eine Überhöhung vorliegt,
flacher ist als an der offenen Seite des zu schneidenden Produktes.
Die Vorrichtung 1 kann zum Beschneiden von einzelnen oder gestapelten
mehrblättrigen Druckprodukten, wie Zeitschriften
jeder Art, Broschuren, Buchblöcken, Bücher, Katalogen oder
auch losen Blättern und Bahnen sowohl im Stillstand als auch
im ununterbrochenen Durchlauf verwendet werden. Fig. 1 further shows that the leg-
If, for example, there is a head or foot trimming of a printed product or several printed products lying one above the other, then the acute cutting angle β, γ can be chosen to be unequal in size, that is to say, for example, that the cutting angle on the side of the collar where there is an elevation is flatter than on the other side open side of the product to be cut.
The device 1 can be used for trimming individual or stacked multi-sheet printed products, such as magazines of all kinds, brochures, book blocks, books, catalogs or also loose sheets and webs, both at a standstill and in an uninterrupted run.
