Abstract
Description
Die Erfindung betrifft eine Einrichtung zur einfachen Umstel lung der Produktion von gleichlangen Abschnitten auf stetig abwechselnd kurz bzw. länger abgeschnittene Produkte ("Kurz- Lang-Schnitt") an Falzwerken.The invention relates to a device for simple changeover production of sections of the same length on steady alternately short or longer cut products ("short Long cut ") on folding units.
Die Erfindung geht von einem Falzapparat aus, der sowohl für die Sammel- als auch Normalproduktion verwendet werden kann. Bei Sammelproduktion wird der Deckbogen länger abgeschnitten als der Abschnitt der Einlage. Aus der DE-PS 6 71 790 ist ein Schneidzylinder bekannt, dessen zwei Schneidmesser so ange ordnet sind, daß sie den Umfang des Zylinders in verschieden lange Abschnitte teilen. Durch diese Anordnung werden im stetigen Wechsel lange und kurze Bögen abgeschnitten. Nach dem Falzen decken sich die Kanten des äußeren Bogens mit denen der Einlage. Bei nicht mehr nachträglich beschnittenen Produkten wird dadurch eine Staffelung vermieden und bei nachträglich beschnittenen vermeidet man damit das sogenannte Schnitzelproblem. Wobei unter Schnitzelbroblem das Abschnei den sehr schmaler Papierstreifen (Schnitzel) - vom äußeren Bogen - gemeint ist, die beim Beschneiden des gesammelten Produkts in der Nachbearbeitung entstehen.The invention is based on a folder, both for the collective as well as normal production can be used. The cover sheet is cut longer in the case of collective production than the section of the insert. From DE-PS 6 71 790 is a Known cutting cylinder, the two cutting knives so attached arranges that they vary the circumference of the cylinder split long sections. With this arrangement continuous alternating long and short sheets cut off. To the edges of the outer sheet coincide with the folding those of the insert. In the case of no longer trimmed Products are thereby avoided and staggered you can avoid the so-called Schnitzel problem. The cutting off under the schnitzel problem the very narrow paper strip (schnitzel) - from the outside Bow - is meant when trimming the collected Product in post processing.
Bei Umrüstung der Druckmaschine auf die Produktion gleichlan ger Abschnitte, die nicht gesammelt werden, müssen die Schneidmesserleisten versetzt werden. Bei ansonsten automati sierten Umrüstungsvorgängen an Druckmaschinen besteht die Gefahr, diesen manuellen Umbau zu vergessen. Dies führt zu vermehrter Makulatur und erfordert den Abbruch des Druckvor gangs.When converting the printing press to production, the same Any sections that are not collected must include the Cutting knife bars are offset. With otherwise automatic There is a retrofitting process on printing presses Danger of forgetting this manual modification. this leads to increased waste and requires the print job to be canceled gangs.
Die Erfindung hat die Aufgabe, eine Einrichtung zu schaffen, mit der die Position von Schneidmessern am Umfang von Schneidmesserzylindern automatisch verändert werden kann. Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Patentansprüche gelöst.The invention has for its object to provide a device with which the position of cutting knives on the circumference of Cutting knife cylinders can be changed automatically. The object is achieved by the characterizing Features of the claims solved.
Durch die Erfindung kann eine Umrüstung der Messerzylinder von "Kurz-Langem" auf gleichlanges Abschneiden ohne manuelles Eingreifen vorgenommen werden. Die Erfindung ermöglicht ein automatisiertes, schnelles Umrüsten eines Falzwerkes von Sammel- auf Normalproduktion und umgekehrt.The invention enables retrofitting of the knife cylinder from "short-long" to the same length of cutting without manual Intervention can be made. The invention enables automated, fast Converting a folder from collective to normal production and vice versa.
Anhand der nachfolgenden Ausführungsbeispiele wird die Erfin dung näher erläutert.Based on the following embodiments, the inven explained in more detail.
Die Zeichnungen zeigen im einzelnen:The drawings show in detail:
Fig. 1 Seitenansicht eines Schneidmesserzylinders Fig. 1 side view of a cutting knife cylinder
Das in Fig. 1 dargestellte Ausführungsbeispiel zeigt einen Schneidmesserzylinder (1) in der Seitenansicht, der gegenüber einem am Umfang fix angebrachten Messer (7) einen Träger (30) aufweist. An diesem um eine Drehachse (31) drehbar gelagerten Träger (30) sind zwei Messer (32, 33) montiert. In der darge stellten Stellung fluchtet ein Messer (33) mit der Drehachse (31), mit der Symmetrieachse des Schneidmessserzylinders (1) und einem fest angebrachten Messer (7). In dieser Einstellung werden gleichlange Abschnitte produziert. Auf der - dem Messer (33) gegenüberliegenden - Fläche des Trägers (30) befindet sich ein weiteres Messer (32), das um die Strecke s gegenüber der Flucht versetzt ist. Dieses Messer (32) oder weitere Messer, die um unterschiedliche Strecken s gegenüber der Schwenkachse versetzt sind, kann bzw. können auch auf anderen - umfangsseitig beliebig angeformten - Flächen des Messerträgers (30) angeordnet sein. Über eine Übertragungs einrichtung (35) wird dieses Messer (32) von einem Antrieb (34) in seine umfangsseitige Arbeitsposition bewegt. In dieser Position teilt das Messer (32) den Umfang des Schneid messerzylinders (1) in zwei unterschiedlich lange Abschnitte zur Herstellung von Sammelprodukten.The exemplary embodiment shown in FIG. 1 shows a cutting knife cylinder ( 1 ) in side view, which has a carrier ( 30 ) in relation to a knife ( 7 ) fixedly attached to the circumference. Two knives ( 32 , 33 ) are mounted on this carrier ( 30 ) which is rotatably mounted about an axis of rotation ( 31 ). In the illustrated position, a knife ( 33 ) is aligned with the axis of rotation ( 31 ), with the axis of symmetry of the cutting knife cylinder ( 1 ) and a fixed knife ( 7 ). In this setting, sections of the same length are produced. On the surface of the carrier ( 30 ) opposite the knife ( 33 ) there is another knife ( 32 ) which is offset by the distance s from the flight. This knife ( 32 ) or other knives, which are offset by different distances s from the swivel axis, can also be arranged on other surfaces of the knife carrier ( 30 ) which are shaped on the circumference as desired. Via a transmission device ( 35 ) this knife ( 32 ) is moved by a drive ( 34 ) into its circumferential working position. In this position, the knife ( 32 ) divides the circumference of the cutting cylinder ( 1 ) into two sections of different lengths for the production of generic products.
Als Antrieb zum Verdrehen des Trägers (30) kann auch ein pneumatischer Schwenkzylinder stirnseitg an die Drehachse (31) angeflanscht werden.As a drive for rotating the carrier ( 30 ), a pneumatic swivel cylinder can also be flange-mounted on the end of the axis of rotation ( 31 ).
Die noch freien Flächen des Trägers (30) können mit weiteren Messern besetzt werden, die entweder als Ersatz für ver schlissene Messer (32, 33) eingesetzt werden oder um eine betragsmäßig unterschiedliche Strecke s versetzt angebracht werden, damit auch Bahnen verschiedener Dicke für die Sammel produktion geschnitten werden können. The still free surfaces of the carrier ( 30 ) can be occupied with further knives, which are either used as a replacement for worn out knives ( 32 , 33 ) or are offset by a different amount s, so that webs of different thicknesses for the collection production can be cut.
