Description

Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

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 claim 1.
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.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung. Further advantageous features result from the dependent ones Claims, the following description and the Drawing.

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 device 33 shown in FIGS. 1 and 2 has two Units A and B, each consisting essentially of one Cutting knife 5 and the endless transport members 9, 11 exist. The transport member 11 can also be designed as a counter knife his. The two units A and B are in accordance with FIG Distance to each other mounted on the axis 12. At least one of the two units A and B is axially adjustable on the axis 12. The distance between the two units A and B can thus be enlarged or reduced.

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 cutting knife 5 consists of a plurality of planes Blades 7, each having a cutting edge 6, with the circumference 31 of a counter knife 11 a tapered Form cutting gap 8, as shown in Fig. 1. At a First blade 7a, this cutting gap 8 is the largest and takes up to a blade 7b at the rear end of the cutting knife 5 steadily. The blades 7 are fixed but interchangeable connected with a knife holder and form the frame fixed Cutting knife 5. The cutting knife 5 could in principle also be made from a single piece, but what the Manufacturing costs would increase significantly. Individual blades 7 can also be reground more easily. As can be seen the cutting knife 5 is approximately circular-arc-shaped.

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 counter knife 11 is rotatably mounted on the axis 12 or is designed to be stationary. In the first case, it forms a circular disk with the lateral surface 31 which, according to FIG. 2, is coaxial to the axis 12. The distance between the two counter knives 11 is adapted to the format of the product 1. The products 1 are each pressed with an underside 4 onto the lateral surfaces 31 of the two counter knives 11. On the outside, a stationary or rotating disc 13 or guide can be arranged concentrically with the axis 12 for each counter knife 11, which serves to support a chip 34 to be cut off and, if necessary, to remove it, as shown in FIG. 3.
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 transport members 9 are guided, for example, in a known manner and tensioned endless belts, endless chains, timing belts or similar. 1 shows the transport elements 9 with a lower run 9a at an angle of about 180 ° led around the counter knife 11. The direction of the parallel guided transport members 9 is in Fig. 1 by the Arrow 35 indicated. The upper run 9b thus runs in FIG. 1 from right to left and the lower run 9a from left to right. The transport members 9 act comparatively in the area large deflection roller 15 with a feed belt 21 together, which is placed around guide rollers 22, 23 and 24. The Deflection roller 15 forms with the transport members 9 and the deflection belt 21 an inlet, which is indicated by an arrow 30 is. The feed to be cut is fed in at this inlet Products 1 in the cutting gap 8. Form the products 1 for example, a stream of shingles 29, which consists of the products 1, for example from brochures, magazines or printed sheets is formed.

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 transport members 9 are, for example, of a drive roller 14 driven, which is indicated by an arrow 36 Output is arranged. In the erection after the Drive roller 14, a tensioning station 18 is arranged, the two Has tension rollers 17 and 18 and a tension spring 20. Such Tensioning stations 18 are well known to those skilled in the art. Between the tensioning station 18 and the deflection roller 15 is one further deflection roller 16 arranged.

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 transport members 9 works with a rotating counter knife 11 for the transport and guidance of the cut Print products 1 in the area of the cutting knife 5 together. The lower run 9a is in each case against a cutting knife 11 stretched so that in the area of the cutting knife 5 the printed products 1 between the two transport elements 9 and the two Counter knives 11 are held clamped.

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 transport members 9 is the transport speed of the two counter knives 11 customized. After the deflection roller 15, the products 1 are passed through the two transport members 9 and the counter knife 11 in the Cutting gap 8 introduced and over the entire area of Cutting knife 5 taken. As mentioned above, the Cutting gap 8 tapers in the transport direction, penetrate the Cutting edges 6 from the top 3 of the products 1 into this and cut each along a cutting line 32 (Fig. 2) from each side a chip 34. The cutting knife 5 each work with one cutting edge during the cutting process 31a of a counter knife 11 together. These cutting edges 31a are circular and are arranged on the outside of the counter knife 11. In the case of the blades 7b arranged at the ends, the Cutting process completed and the two chips 34 are completely separated as shown in Figure 3. The severed Chips 34 come down to a co-rotating one Disk 3 and are transported away from this. The co-rotating Disc 3 simultaneously supports chip 34 and helps cut the product completely. In the area of the drive roller 14, the cut printed products 1 a are transported away and further processing devices, not shown here fed.

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 products 1 can be operated simultaneously from the underside 4 by means of stationary, internal ones Cutting knife 10 can be cut. This is particularly the case with very thin envelopes of products 1 advantageous. The inside Cutting knife 10 can according to FIG Part of the cutting knife 5 or over the entire Range. The internal knives are preferably also made from several blades. In principle, each cutting knife 5 can also have an internal one Cutting knife 5 to be replaced. In this case the printed products 1 thus cut from the bottom 4 forth. An embodiment is also conceivable in which only a unit A or B is provided and in which only one of the two sides 2 is cut. Basically is with the device 33 according to the invention also a front and / or a back cut of a printed product is possible. On Front cut could be shown in another one not shown here upstream or downstream station.
