Description

Die Erfindung betrifft eine Vorrichtung zum seitlichen Ausrichten von Bogen mit einer die Bogen erfassenden und mit der Seitenkante gegen einen Seitenanschlag führenden Saugeinrichtung, die mindestens eine mit Saugbohrungen versehene Saugplatte aufweist.The invention relates to a device for laterally aligning sheets with a sheet detecting the suction and leading with the side edge against a side stop suction device having at least one provided with suction holes suction plate.

Derartige Vorrichtungen zum seitlichen Ausrichten der in der Regel schuppenförmig einer Druckmaschine zugeführten Bogen sind allgemein bekannt und im Anlegtisch so angeordnet, dass die Saugeinrichtung bündig mit der Oberfläche des Anlegtischs abschließt. Die Saugeinrichtung weist mindestens eine mit Saugbohrungen versehene Saugplatte auf, wobei die Saugöffnungen in die Oberfläche der Saugplatte münden. Die Saugbohrungen werden taktweise mit Saugluft beaufschlagt, der jeweils über der Saugeinrichtung liegende Bogen angesaugt, die Saugeinrichtung mittels eines Antriebs quer zur Bogenförderrichtung verschoben, damit der Bogen mit der Seitenkante gegen einen Seitenanschlag geführt und so nach der Seitenkante ausgerichtet.
Bei der Verarbeitung schwerer oder spezieller Bedruckstoff, wie z. B. einseitig abgedeckten Wellkarton, ist es erforderlich, dass durch die Saugeinrichtung eine hohe Haltekraft realisiert wird.Such devices for the lateral alignment of the usually flaky fed to a printing press sheet are well known and arranged in the feed table so that the suction device is flush with the surface of the feed table. The suction device has at least one suction plate provided with suction holes, wherein the suction openings open into the surface of the suction plate. The suction holes are cyclically acted upon by suction, each sucked over the suction bow, the suction moved by a drive transversely to the sheet conveying direction, so that the sheet is guided with the side edge against a side stop and so aligned with the side edge.
When processing heavy or special substrate, such as. B. unilaterally covered corrugated cardboard, it is necessary that a high holding force is realized by the suction device.

Aus der DE 44 15 494 C2 ist hierzu eine Lösung bekannt, bei der das durch die Anordnung der Saugöffnungen erreicht werden soll. Es ist eine Saugplatte vorgesehen, die mindestens zwei unterschiedliche Haltekräfte aufbringende Bereiche aufweist. In dem Bereich, der dem Seitenanschlag zugewandt ist, wird durch die Anzahl und Anordnung der Saugöffnungen eine geringere Haltekraft erzeugt. Beim Unterfahren des Seitenanschlags durch die Saugplatte wird dann die auf den Bogen wirkende Haltekraft nacheinander jeweils nur um die Haltekraft zweier Saugbohrungen reduziert.From the DE 44 15 494 C2 For this purpose, a solution is known in which to be achieved by the arrangement of the suction openings. It is provided a suction plate having at least two different holding forces applying areas. In the area which faces the side stop, a smaller holding force is generated by the number and arrangement of the suction openings. When driving under the side stop by the suction plate then acting on the arc holding force is successively reduced only by the holding force of two suction holes.

Trotz dieser Maßnahme ist es nicht möglich, die gesamte Palette der zur Verarbeitung gelangenden schweren oder speziellen Bedruckstoffe durch die Saugeinrichtung zu erfassen und sicher bezüglich der Seitenkante auszurichten. Es ist deshalb erforderlich, dafür eine Schiebemarke vorzusehen und diese bei Bedarf einzubauen, was zu einem Mehraufwand sowie zu einer Formateinschränkung führt.Despite this measure, it is not possible to detect the entire range of heavy or special substrates to be processed by the suction device and to reliably align them with respect to the side edge. It is therefore necessary to provide a shift mark for this purpose and to install it if necessary, which leads to an overhead and to a format restriction.

In der JP-A-60 067948 wird eine Einrichtung vorgestellt, durch die plattenförmige Gegenstände von einem Plattenvorratsstapel vereinzelt und auf eine Montageplatte verbracht werden können. Auf der Montageplatte werden diese durch Rollen gegen in Förderrichtung und seitwärts platzierte Positionierstifte gefördert. Dabei wird die Montageplatte mit Unterdruck beaufschlagt, wodurch die plattenförmigen Gegenstände beim Erreichen ihrer Endlage auf der Montageplatte fixiert werden. Hierzu sind in die Montageplatte längs und quer zur Förderrichtung der plattenförmigen Gegenstände Nuten eingebracht, die mit Saugluftbohrungen verbunden sind.In the JP-A-60 067948 a device is presented by the plate-shaped objects can be separated from a plate storage stack and spent on a mounting plate. On the mounting plate these are by rolling against in the conveying direction and laterally placed positioning pins promoted. In this case, the mounting plate is subjected to negative pressure, whereby the plate-shaped objects are fixed on reaching the end position on the mounting plate. For this purpose, grooves are longitudinally and transversely to the conveying direction of the plate-shaped objects introduced into the mounting plate, which are connected to Saugluftbohrungen.

Bei dieser Lösung wird nicht die Saugplatte mit dem angesaugten Verarbeitungsgut gegen eine Seitenmarke geschoben, sondern das Verarbeitungsgut wird relativ zur Saugplatte bewegt und erst in der Endstellung auf dieser festgesaugt.In this solution, the suction plate with the sucked processing material is not pushed against a side mark, but the processed material is moved relative to the suction plate and only sucked in the end position on this.

Aus der DE 198 24 834 A1 ist eine Vorrichtung zum Ausrichten von Bogen mit einer Seitenzieheinrichtung bekannt. Der Seitenzieheinrichtung ist eine Halteeinrichtung mit einem Sauger zugeordnet, wobei der Sauger Führungen aufweist, die als Kolben ausgebildet sind und in gestellfest dem Anlegtisch zugeordneten Lagerstücken vorgesehenen Zylindern parallel zu Vordermarken verschiebbar gelagert sind. Die Zylinder sind wahlweise derart mit einem Druckmedium beaufschlagbar, dass der Sauger durch die Wirkung des Druckmediums in Ziehrichtung, die Ziehbewegung der der Halteeinrichtung zugeordneten Zieheinrichtung unterstützend oder der Ziehbewegung entgegenwirkend verbringbar ausgeführt ist.From the DE 198 24 834 A1 a device for aligning sheets with a side pulling device is known. The side pulling device is associated with a holding device with a vacuum cleaner, wherein the suction device has guides which are designed as pistons and are mounted displaceably parallel to front marks in cylinders fixedly provided in the bearing table for bearing plates. The cylinders are optionally acted upon by a pressure medium, that the sucker by the action of the pressure medium in the drawing direction, the pulling movement of the holding device associated pulling device supportive or the drawing movement is carried out counteracting available.

In derIn the FR 724.512 FR 724,512 wird eine Seitenzieheinrichtung gezeigt, bei der pro Seitenzieheinrichtung eine einzige große Saugöffnung angeordnet ist. Diese ist einer Reihe von in Ziehrichtung ausgerichteten Nuten zugeordnet.a side puller is shown in which there is one single large suction port per side puller. This is assigned to a number of aligned in the direction of drawing grooves.

Die EP 1 454 757 A2 beschreibt eine Lösung für eine bogen- oder blattförmigen Bedruckstoff verarbeitende Einrichtung, bei der mehrer Saugbänder nebeneinander angeordnet sind. Dabei werden die Saugbänder über zugeordnete Saugöffnungen mit Saugluft versorgt. Das geschieht derart, dass die Durchmesser der am Rand der Transportstrecke liegenden Saugöffnungen größer als die der mittig angeordneten sind.The EP 1 454 757 A2 describes a solution for a sheet or sheet-shaped printing material processing device, in which a plurality of suction belts are arranged side by side. The suction belts are supplied with suction air via assigned suction openings. This happens in such a way that the diameters of the suction openings located at the edge of the transport path are greater than those of the centrally arranged.

Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung zum seitlichen Ausrichten durch einfache Mittel so zu verändern, dass auch schwere und spezielle Bedruckstoffe problemlos erfasst und nach der Seitenkante ausgerichtet werden können.The object of the invention is to modify a generic device for lateral alignment by simple means so that even heavy and special substrates can be easily detected and aligned to the side edge.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung nach den Merkmalen des Anspruchs 1 gelöst.According to the invention the object is achieved by a device according to the features of claim 1.

Durch die erfindungsgemäße Lösung ist es möglich, auch schwere Bedruckstoffe oder solche, die auf Grund ihrer Ausbildung nicht sicher von der den Bogen gegen den Seitenanschlag führenden Saugeinrichtung erfasst werden können, problemlos nach der Seitenkante auszurichten. Dabei wird die Vorrichtung mit einfachen Mitteln und ohne eine Formateinschränkung realisiert.The inventive solution, it is possible, even heavy substrates or those that can not be reliably detected by the arc leading to the side stop suction device due to their training, easily align with the side edge. In this case, the device is realized by simple means and without a format restriction.

a section along the line BB in Fig. 1 ,

In der Fig. 1 ist eine Saugeinrichtung 1, die aus einer Saugplatte 2 und z. B. einem Doppelsauger 3 besteht, dargestellt. Die Saugeinrichtung 1 ist in einer Saugziehschiene 4 angeordnet, die durch nicht dargestellte Mittel quer zu einer Bogenförderrichtung 5 im Maschinentakt in Richtung eines ortsfest angeordneten Seitenanschlag 6 bewegt und von diesem zurückgeführt wird. Dazu ist die Saugziehschiene 4 verschiebbar in einem Anlegtisch 7 gelagert, wobei die Oberfläche des Anlegtischs 7 mit der Oberfläche der Saugziehschiene 4 eine Ebene bildet. In der Saugplatte 2 sind Saugbohrungen 8 vorgesehen, die über einen nicht dargestellten Saugkasten, der mit einer Unterdruckversorgung in Verbindung steht, mit Unterdruck beaufschlagt werden. Die Saugbohrungen 8 sind mit Saugöffnungen 8.1 versehen, die in einen Nutengrund 9.1 von Nuten 9 münden. Die Nuten 9 sind in der Saugziehschiene 4 bzw. in der Saugplatte 2 angeordnet und zum ausrichtenden Bogen hin geöffnet. Die Nuten 9 können in einer beliebigen Lage auf der Saugplatte 2 angeordnet sein. D. h., sie können, wie in Fig. 1 gezeigt, quer zur Bogenförderrichtung 5 oder parallel bzw. geneigt dazu in der Saugplatte 2 angeordnet sein. Sind die Nuten 9 quer zur Bogenförderrichtung 5 oder geringfügig geneigt dazu angeordnet, ist es vorteilhaft, um ein Verhaken der geförderten Bogen zu vermeiden, die in Bogenförderrichtung 5 vom liegenden Nutwandungen 10 in Bogenförderrichtung 5 geneigt auszuführen, wobei sich ein Winkel α von etwa 60° als vorteilhaft erwiesen hat.
Die Bogen werden in bekannter Weise von einem Bändertisch schuppenförmig auf den Anlegtisch 7 gefördert und der jeweils vorderst Bogen des Bogenstroms mit der Vorder- . kante gegen am Anlegtisch 7 positionierten Vordermarken transportiert und so nach der Vorderkante ausgerichtet. Danach werden, wenn wie im Ausführungsbeispiel Doppelsauger 3 in der Saugziehschiene 4 angeordnet sind, diese und die Saugbohrungen 8 der Saugplatte 2 aktiviert, indem sie mit Unterdruck beaufschlagt werden. Durch die Maßnahme, die Saugöffnungen 8.1 statt an der Oberfläche der Saugplatte 2 im Nutgrund 9.1 der zum auszurichtenden Bogen hin geöffnete Nuten 9 anzuordnen, wird die wirksame Saugfläche der Saugplatte 2 vergrößert. Außerdem hat sich gezeigt, dass sich z. B. die Welle bei einseitig abgedeckten Wellenkarton oder das Material bei schweren Bedruckstoffen nach Beaufschlagung der Nuten 9 mit Unterdruck nicht nur gegen die Saugplatte 2 gezogen wird, sondern sich geringfügig elastisch verformend der Kontur der Nuten 9 anpasst. Damit wird ein Quasiformschluss zwischen dem auszurichtenden Bogen sowie den Nuten 9 der Saugpalette 2 realisiert und so eine hohe Ziehkraft ermöglicht, so dass auch schwere oder spezielle Bedruckstoffe sicher erfasst und ebenso mit der Seitenkante gegen den Seitenanschlag 6 geführt werden.
Danach wird in bekannter Weise die Saugluftzufuhr zum Doppelsauger 3 sowie zur Saugplatte 2 unterbrochen und der nach Vorder- und Seitenkante ausgerichtete Bogen durch nicht dargestellte Mittel in die nachgeordnete Maschine gefördert.
Da die Saugziehschiene 4 mit zum ausrichtenden Bogen hin geöffnete Nuten 9 nicht zum Ausrichten beliebiger Bedruckstoffe geeignet ist, kann diese ausgewechselt werden. Dazu sind in der Saugziehschiene 4 Bohrungen 11 vorgesehen, so dass die Saugzeihschiene 4 mit einem Schlitten verbunden werden kann, der im Anlegtisch 7 gelagert und quer zur Bogenförderrichtung 5 im Arbeitstakt verschoben werden kann. Es ist auch möglich, lediglich die Saugplatte 2 austauschbar zu gestalten und diese bei Bedarf zu wechseln.In the Fig. 1 is a suction device 1, which consists of a suction plate 2 and z. B. a double suction 3 is shown. The suction device 1 is arranged in a Saugziehschiene 4, which moves by means not shown transversely to a sheet conveying direction 5 in the machine cycle in the direction of a fixedly arranged side stop 6 and is returned by this. For this purpose, the Saugziehschiene 4 is slidably mounted in a feed table 7, wherein the surface of the feed table 7 with the surface of Saugziehschiene 4 forms a plane. In the suction plate 2 suction holes 8 are provided, which are acted upon by a suction box, not shown, which is in communication with a vacuum supply, with negative pressure. The suction holes 8 are provided with suction openings 8.1, which open into a groove bottom 9.1 of grooves 9. The grooves 9 are arranged in the Saugziehschiene 4 and in the suction plate 2 and opened to the aligning bow. The grooves 9 may be arranged in any position on the suction plate 2. That is, they can, as in Fig. 1 shown, transversely to the sheet conveying direction 5 or parallel or inclined to be arranged in the suction plate 2. If the grooves 9 are arranged transversely to the sheet conveying direction 5 or slightly inclined thereto, it is advantageous to avoid entanglement of the conveyed sheets which are inclined in the sheet conveying direction 5 from the lying groove walls 10 in the sheet conveying direction 5, wherein an angle α of approximately 60 ° has proved to be advantageous.
The sheets are conveyed in a known manner by a belt table scaly on the feed table 7 and the respective foremost sheet of the sheet flow with the front. transported edge against positioned at the feed table 7 leading brands and so aligned to the front edge. Thereafter, if, as in the embodiment, double suckers 3 are arranged in the Saugziehschiene 4, these and the suction holes 8 of the suction plate 2 is activated by being subjected to negative pressure. By the measure, the suction openings 8.1 instead of on the surface of the suction plate 2 in the groove bottom 9.1 of the sheet to be aligned open grooves 9, the effective suction surface of the suction plate 2 is increased. In addition, it has been shown that z. As the wave is covered with unilaterally covered wave board or the material in heavy substrates after exposure of the grooves 9 with negative pressure not only against the suction plate 2, but slightly elastically deforming the contour of the grooves 9 adapts. In order for a Quasiformschluss between the sheet to be aligned and the grooves 9 of the suction pallet 2 is realized, thus enabling a high pulling force, so that even heavy or special substrates safely detected and also performed with the side edge against the side stop 6.
Thereafter, in a known manner, the suction air supply to the double suction 3 and the suction plate 2 is interrupted and the forward and side edge aligned sheet promoted by means not shown in the downstream machine.
Since the Saugziehschiene 4 is not suitable for aligning any substrates with aligned to the aligning bow grooves 9, this can be replaced. For this purpose, 4 holes 11 are provided in the Saugziehschiene, so that the Saugzeihschiene 4 can be connected to a carriage which can be stored in the feed table 7 and moved transversely to the sheet conveying direction 5 in the power stroke. It is also possible to make only the suction plate 2 interchangeable and to change them if necessary.
