Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff
des Anspruchs 1.The invention relates to a device according to the preamble
of
Eine Vorrichtung der genannten Art ist im Stand der Technik aus der EP 0 670 203 bekannt geworden. Bei dieser ist im Unterschied zu den üblichen Schneidvorrichtungen das Schneidmesser stillstehend angeordnet und die zu schneidenden Produkte bewegen sich auf das Schneidmesser zu. Die Produkte passieren das Schneidmesser und und werden dabei mit einem Ziehschnitt geschnitten. Hierbei sind die Schnittkräfte erheblich und die Produkte müssen beim Schneidvorgang sehr gut gehalten und geführt sein, damit ein einwandfreier Schnitt entsteht. Bei der genannten Vorrichtung nach dem Stand der Technik werden die zu schneidenden Produkte jeweils auf einem Wagen festgeklemmt. Dies geschieht mit einer Zange. Die Wagen, auf denen jeweils ein Produkt festgeklemmt ist, sind auf einer Führungsschiene gelagert. Bei dieser Bewegung dringt das Schneidmesser in das Produkt ein. Diese Vorrichtung hat den Nachteil, dass eine ungetaktete, fliessende Verarbeitung von Produkten nicht möglich ist. Insbesondere ist es nicht möglich, einen Schuppensturm von Druckprodukten kontinuierlich zu schneiden. Zur Verarbeitung eines Schuppenstroms müssten die einzelnen Produkte jeweils auf einem Wagen festgehalten und somit getaktet geschnitten werden.A device of the type mentioned is in the prior art become known from EP 0 670 203. This is different to the usual cutting devices the cutting knife arranged stationary and the products to be cut move towards the cutting knife. The products happen the cutting knife and and are doing a drawing cut cut. The cutting forces are considerable and the Products must be held and guided very well during the cutting process be so that a perfect cut is created. In the mentioned device according to the prior art to cutting products each clamped on a trolley. This is done with a pair of pliers. The wagons on each a product is clamped are on a guide rail stored. With this movement the cutting knife penetrates into the Product. This device has the disadvantage that an unclocked, fluent processing of products not possible is. In particular, it is not possible to have a scale storm to cut printed products continuously. For processing the individual products would have to have a shingled stream held on a trolley and thus cut clocked become.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, mit der Produkte auch taktlos geschnitten werden können.The invention has for its object a device to create the type mentioned, with which products can also be cut tactlessly can be.
Die Aufgabe ist gemäss Anspruch 1 gelöst.
Bei der erfindungsgemässen Vorrichtung weist das Transportmittel
wenigstens ein endloses Transportorgan auf, mit dem die
Produkte gehalten und beim Schneidvorgang geführt werden. Mit
einem solchen Transportorgan kann auch ein Schuppenstrom beispielsweise
aus Druckprodukten, insbesondere Broschüren, Zeitungen
und dergleichen kontinuierlich transportiert und geschnitten
werden.
Eine besonders einfache Führung und Halterung der Produkte ergibt
sich dann, wenn gemäss einer Weiterbildung der Erfindung
der Beschnitt auf einer gekrümmten Bahn erfolgt und das eine
Transportmittel als mitdrehendes Gegenmesser ausgebildet ist.
Damit kann auch bei hohem Schneiddruck das zu schneidende Produkt
schlupf- und reibungsfrei gehalten werden.
Das Gegenmesser ist vorzugsweise gleichzeitig auch Einzug- und
Transportorgan. Die zu schneidenden Produkte werden vorzugsweise
zwischen dem genannten endlosen Transportorgan und dem
Gegenmesser transportiert. Zwischen diesen beiden Transportelemente
können die Produkte beim Schneidvorgang besonders zuverlässig
transportiert und stabil gehalten werden. Dies ist
dann besonders der Fall, wenn das Transportorgan ein endloses
Band, eine endlose Kette oder ein endloser Zahnriemen ist.The object is achieved according to
In the device according to the invention, the transport means has at least one endless transport element with which the products are held and guided during the cutting process. With such a transport member, a shingled stream, for example of printed products, in particular brochures, newspapers and the like, can also be transported and cut continuously.
A particularly simple guidance and holding of the products is obtained if, according to a further development of the invention, the trimming takes place on a curved path and the one means of transport is designed as a counter knife rotating with it. This means that the product to be cut can be kept free of slippage and friction even with high cutting pressure.
The counter knife is preferably also the feed and transport member at the same time. The products to be cut are preferably transported between said endless transport member and the counter knife. Between these two transport elements, the products can be transported particularly reliably and kept stable during the cutting process. This is particularly the case when the transport member is an endless belt, chain or toothed belt.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass das Schneidmesser, das Transportorgan und das Gegenmesser eine Einheit bilden. Sind zwei solche Einheiten spiegelbildlich im Abstand nebeneinander angeordnet, so eignet sich die Vorrichtung besonders für den Kopf- und Fussschnitt von Druckprodukten. Kopf- und Fussschnitt können dann gleichzeitig in einer Station durchgeführt werden. Die erfindungsgemässe Vorrichtung eignet sich insbesondere zum Schneiden von Druckprodukten, wie Zeitungen, Papierstapel, Broschüren, Bücher und dergleichen. Die Druckprodukte können unregelmässig, einzeln oder im Schuppenstrom der erfindungsgemässen Vorrichtung zugeführt, verarbeitet und weggeführt werden. Dies ermöglicht eine sehr hohe Schneidleistung.According to a development of the invention, it is provided that the cutting knife, the transport member and the counter knife one Form unity. Are two such units mirrored in the The device is suitable for spacing next to one another especially for the head and foot cut of printed products. Head and foot cuts can then be done in one at the same time Station. The device according to the invention is particularly suitable for cutting printed products such as Newspapers, piles of paper, brochures, books and the like. The printed products can be irregular, individually or in a shingled stream fed to the device according to the invention, processed and be led away. This enables a very high one Cutting performance.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die genannten beiden Einheiten in ihrem Abstand zueinander verstellbar sind. Dies ermöglicht eine Anpassung an unterschiedliche Formatbreiten. Mit der gleichen Vorrichtung können somit unterschiedliche Formate geschnitten werden. Die Einstellung ist vergleichsweise einfach, da lediglich der Abstand zwischen den Einheiten eingestellt werden muss. Vorzugsweise sind die beiden Gegenmesser auf der gleichen Achse gelagert. Zur Einstellung genügt somit das Verstellen einer Einheit auf dieser Achse.According to a development of the invention, it is provided that the two units mentioned in their distance from each other are adjustable. This enables adaptation to different ones Format widths. With the same device can thus different formats can be cut. The setting is comparatively easy because only the distance must be set between the units. Preferably the two counter knives are mounted on the same axis. Adjusting a unit is therefore sufficient for setting this axis.

Die in den Fig. 1 und 2 gezeigte Vorrichtung 33 weist zwei
Einheiten A und B auf, die jeweils im wesentlichen aus einem
Schneidmesser 5 und den endlosen Transportorganen 9, 11 bestehen.
Das Transportorgan 11 kann auch als Gegenmesser ausgebildet
sein. Die beiden Einheiten A und B sind gemäss Fig. 2 im
Abstand zueinander auf der Achse 12 gelagert. Wenigstens eine
der beiden Einheiten A und B ist auf der Achse 12 achsial verstellbar.
Der Abstand zwischen den beiden Einheiten A und B
kann somit vergrössert oder verkleinert werden.The
Das Schneidmesser 5 besteht aus einer Mehrzahl von ebenen
Klingen 7, die jeweils eine Schneidkante 6 aufweisen, die mit
dem Umfang 31 eines Gegenmessers 11 einen sich verjüngenden
Schneidspalt 8 bilden, wie dies in Fig. 1 gezeigt ist. Bei einer
ersten Klinge 7a ist dieser Schneidspalt 8 am grössten und
nimmt bis zu einer Klinge 7b am hinteren Ende des Schneidmessers
5 stetig ab. Die Klingen 7 sind fest aber auswechselbar
mit einem Messerträger verbunden und bilden das gestellfeste
Schneidmesser 5. Das Schneidmesser 5 könnte grundsätzlich auch
aus einem einzigen Stück hergestellt werden, was jedoch die
Herstellungskosten wesentlich erhöhen würde. Einzelne Klingen
7 können zudem einfacher nachgeschliffen werden. Wie ersichtlich,
ist das Schneidmesser 5 etwa kreisbogenförmig ausgebildet.The
Das Gegenmesser 11 ist rotierend auf der Achse 12 gelagert
oder ortsfest ausgebildet. Es bildet im ersten Fall eine
kreisförmige Scheibe mit der Mantelfläche 31, die gemäss Fig.
2 koaxial zur Achse 12 ist. Der Abstand zwischen den beiden
Gegenmessern 11 ist an das Format des Produktes 1 angepasst.
Die Produkte 1 werden jeweils mit einer Unterseite 4 an die
Mantelflächen 31 der beiden Gegenmesser 11 angepresst. Aussenseitig
kann konzentrisch mit der Achse 12 zu jedem Gegenmesser
11 jeweils eine ortsfeste oder mitdrehende Scheibe 13 oder
Führung angeordnet sein, die dazu dient, einen abzuschneidenden
Span 34 abzustützen und allenfalls abzutransportieren, wie
dies in Fig. 3 gezeigt ist.
Es versteht sich von selbst, dass die zu schneidenden Produkte
in bekannter Weise seitlich in einer hier nicht gezeigten Station
ausgerichtet werden (können), bevor sie der Schneidstation
zugeführt werden.The
It goes without saying that the products to be cut are (as is known) laterally aligned in a station (not shown here) before they are fed to the cutting station.
Die Transportorgane 9 sind beispielsweise in bekannter Art geführte
und gespannte endlose Bänder, endlose Ketten, Zahnriemen
oder dergleichen. Wie die Fig. 1 zeigt, sind die Transportorgane
9 mit einem unteren Trum 9a in einem Winkel von etwa
180° um die Gegenmesser 11 geführt. Die Laufrichtung der
parallel geführten Transportorgane 9 ist in Fig. 1 durch den
Pfeil 35 angegeben. Der obere Trum 9b läuft in Fig. 1 somit
von rechts nach links und der untere Trum 9a von links nach
rechts. Die Transportorgane 9 wirken im Bereich einer vergleichsweise
grossen Umlenkrolle 15 mit einem Zuführband 21
zusammen, das um Führungsrollen 22, 23 und 24 gelegt ist. Die
Umlenkrolle 15 bildet mit den Transportorganen 9 und dem Umlenkband
21 einen Einlauf, der mit einem Pfeil 30 angedeutet
ist. Bei diesem Einlauf erfolgt die Zuführung der zu schneidenden
Produkte 1 in den Schneidspalt 8. Die Produkte 1 bilden
beispielsweise einen Schuppenstrom 29, der aus den Produkten
1, beispielsweise aus Broschüren, Zeitschriften oder Druckbogen
gebildet wird.The
Die Transportorgane 9 sind beispielsweise von einer Antriebsrolle
14 angetrieben, die an einem durch einen Pfeil 36 angedeuteten
Ausgang angeordnet ist. In der Aufrichtung nach der
Antriebsrolle 14 ist eine Spannstation 18 angeordnet, die zwei
Spannrollen 17 und 18 sowie eine Spannfeder 20 aufweist. Solche
Spannstationen 18 sind dem Fachmann an sich gut bekannt.
Zwischen der Spannstation 18 und der Umlenkrolle 15 ist eine
weitere Umlenkrolle 16 angeordnet.The
Jedes der Transportorgane 9 arbeitet mit einem rotierenden Gegenmesser
11 für den Transport und die Führung der zu schneidenden
Druckprodukte 1 im Bereich des Schneidmessers 5 zusammen.
Der untere Trum 9a ist jeweils gegen ein Schneidmesser 11
gespannt, so dass im Bereich des Schneidmessers 5 die Druckprodukte
1 zwischen den beiden Transportorganen 9 und den beiden
Gegenmessern 11 klemmend gehalten sind.Each of the
Die Transportgeschwindigkeit der beiden Transportorgane 9 ist
an die der Transportgeschwindigkeit der beiden Gegenmesser 11
angepasst. Nach der Umlenkrolle 15 werden die Produkte 1 durch
die beiden Transportorgane 9 und die Gegenmesser 11 in den
Schneidspalt 8 eingeführt und über den ganzen Bereich des
Schneidmessers 5 mitgenommen. Da sich wie oben erwähnt, der
Schneidspalt 8 in Transportrichtung verjüngt, dringen die
Schneidkanten 6 von der Oberseite 3 der Produkte 1 in diese
ein und schneiden dabei jeweils entlang einer Schneidlinie 32
(Fig. 2) seitlich jeweils einen Span 34 ab. Die Schneidmesser
5 arbeiten beim Schneidvorgang jeweils mit einer Schneidkante
31a eines Gegenmessers 11 zusammen. Diese Schneidkanten 31a
sind kreisrund und jeweils aussenseitig am Gegenmesser 11 angeordnet.
Bei den an den Enden angeordneten Klingen 7b ist der
Schneidvorgang abgeschlossen und die beiden Späne 34 sind
vollständig abgetrennt, wie in Figur 3 gezeigt. Die abgetrennten
Späne 34 gelangen nach unten auf jeweils eine mitrotierende
Scheibe 3 und werden von dieser abtransportiert. Die mitrotierende
Scheibe 3 stützt gleichzeitig den Span 34 und hilft,
das Produkt vollständig durchzuschneiden. Im Bereich der Antriebsrolle
14 werden die geschnittenen Druckprodukte 1a abtransportiert
und weiteren, hier nicht gezeigten Verarbeitungsvorrichtungen
zugeführt.The transport speed of the two
Beim Schneidvorgang können die Druckprodukte 1 gleichzeitig
von der Unterseite 4 her durch ortsfeste innenwirkende
Schneidmesser 10 geschnitten werden. Dies ist insbesondere bei
sehr dünnen Umschlägen der Produkten 1 vorteilhaft. Die innenwirkenden
Schneidmesser 10 können sich gemäss Fig. 1 über einen
Teilbereich des Schneidmessers 5 oder auch über den gesamten
Bereich erstrecken. Die innenwirkenden Schneidmesser sind
vorzugsweise ebenfalls aus mehreren Klingen hergestellt.
Grundsätzlich kann jedes Schneidmesser 5 auch durch ein innenwirkendes
Schneidmesser 5 ersetzt sein. In diesem Fall werden
die Druckprodukte 1 somit von der Unterseite 4 her geschnitten.
Denkbar ist auch eine Ausführung, bei welcher lediglich
eine Einheit A oder B vorgesehen ist und bei welcher lediglich
eine der beiden Seiten 2 geschnitten wird. Grundsätzlich ist
mit der erfindungsgemässen Vorrichtung 33 auch ein Frontund/oder
ein Rückenschnitt eines Druckproduktes möglich. Ein
Frontschnitt könnte in einer weiteren hier nicht gezeigten
vor- oder nachgeschalteten Station durchgeführt werden.During the cutting process, the printed
