Description

Die Erfindung betrifft eine Einrichtung zur Bildung eines sich senkrecht zu den stehend aneinandergereihten Druckbogen erstreckenden Stapels nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for education one perpendicular to the standing printed sheets extending stack according to the preamble of the claim 1.

Bei einer derartigen bekannten Einrichtung (WO92/21599), die insbesondere zur Bildung von Stapeln von Briefumschlägen dient, werden die Briefumschläge von einer Ablegevorrichtung mit Fächerscheiben vereinzelt dem hinteren Ende des sich auf der Stapelauflage bildenden Stapels zugeführt. Wenn der sich bildende Stapel die gewünschte Größe erreicht hat, werden die beiden Stützelemente, die hinter dem hinteren Ende des sich bildenden Stapels in einer Bereitschaftsstellung aneinanderliegend und mit ihren freien Enden etwas über die Stapelauflage hinausragend verharren, schnell an den das hintere Ende des Stapels bildenden Briefumschlag heranbewegt, so daß sie zwischen dem hinteren Ende des Stapels und dem anschließend zugeführten nächsten Briefumschlag zu liegen kommen. Dabei gelangen zunächst nur die oberen Enden der beiden Stützelemente zwischen den fertigen Stapel und den sich neu bildenden Stapel. Danach bewegen sich die beiden Stützelemente nach oben und dringen dadurch immer tiefer zwischen die sich stapelnden Briefumschläge ein. Gleichzeitig folgen die Stützelemente der Bewegungsrichtung der Stapel. Auf diese Weise dienen die Stützelemente gleichzeitig zur Einleitung der Stapeltrennung als auch zur nachfolgenden Abstützung der getrennten Stapel im weiteren Verlauf der Verarbeitung.With such a known device (WO92 / 21599), which in particular for forming stacks of envelopes the envelopes are used by a filing device with serrated locks isolated on the rear end of the fed to the stack forming stack. If he is forming stack has reached the desired size, the two support elements, which are behind the rear end of the forming stack in a standby position and with their free ends a little bit over the pile support protrude protruding, quickly to the rear end of the stack of envelopes moved so that they between the back end of the stack and the one that follows next envelope to be fed. there only reach the upper ends of the two support elements between the finished stack and the new ones Stack. Then the two support elements move above and thereby penetrate ever deeper between the stacking Envelopes. The support elements follow at the same time the direction of movement of the stack. Serve this way the support elements simultaneously to initiate stack separation as well as for the subsequent support of the separated Stack in the further course of processing.

Bei einer anderen bekannten Einrichtung (AT-B-393 820) wird die Trennvorrichtung von oben her in den auf der Stapelauflage anwachsenden Stapel eingetrieben, wobei die Trennvorrichtung schneidenförmig ausgebildet ist, damit sie zwischen die in dem Stapel mit einem bestimmten Druck in dichter gegenseitiger Anlage gehaltenen Druckbogen eindringen kann. Bei diesem Eintreibevorgang kann jedoch zumindest bei empfindlichem Druckbogenmaterial die Gefahr von Beschädigungen nicht ausgeschlossen werden.At another known facility (AT-B-393 820) the separating device from above into the on the stack support growing stack driven, the separator is designed to be cut between them those in the stack with a certain pressure in denser mutual investment held sheet can penetrate. This drive-in process can, however, at least with sensitive Sheet material the risk of damage cannot be excluded.

Bei einem mit der Bezeichnung 327 unter der Marke Müller Martini bekannten Stangenausleger oder Einrichtung zur Bildung eines Stapels stehend aneinanderliegender Druckbogen (Firmenprospekt Müller Martini "Der Stangenausleger 327 - Automatisierung im mittleren Leistungsbereich", Druckdatum 4.86) werden letztere in Teilschuppenströmen, entsprechend der Länge eines zu bildenden Stapels, in senkrechter Förderrichtung einer Auflage aus zwei parallelen, endlos umlaufenden Ketten zugeführt. Der sich durch eine aus umlaufenden Bändern und der horizontal angetriebenen Auflage bildende Stapel wird an seiner Vorderseite wie an seiner Rückseite durch jeweils eine an Stützelementen der Kette anliegende Endplatte begrenzt. In dieser relativ losen Form wird der Stapel in Richtung seiner Erstreckung zwischen zwei Zangenteile einer Presse versetzt, welche den Stapel von den Enden aus zusammenpreßt und anschließend zur Umreifung seitlich verlegt.One with the designation 327 under the Müller brand Martini known pole delivery or educational facility a stack of printed sheets standing next to each other (Muller Martini company brochure "The boom 327 - automation in the medium performance range ", print date 4.86) the latter are in partial scale flows, corresponding to the Length of a stack to be formed, in the vertical conveying direction an edition of two parallel, endless revolving Chains fed. Which is characterized by an encircling Bands and the horizontally driven support forming Stack will be on its front as on its back by one each resting on support elements of the chain End plate limited. In this relatively loose form, the Stack in the direction of its extension between two pliers parts a press that moves the stack from the ends from and then laterally for strapping relocated.

Bei einer anderen bekannten Einrichtung der Bezeichnung 244 wird der auf den umlaufenden Ketten gebildete Stapel durch eine Preßzange von den Ketten zusammengepreßt, abgehoben und in gepreßtem Zustand zur Umreifung seitlich verschoben.In another known device of the designation 244 becomes the stack formed on the revolving chains pressed from the chains by a pair of pliers, lifted off and laterally shifted for strapping in the pressed state.

Die Bildung der stangenartigen Stapel ist bei diesen Einrichtungen an die Teilung der den Stapel aufnehmenden Ketten gebunden, d. h. auch, daß eine Änderung der Stapellänge nur beschränkt und mit relativ hohem Arbeitsaufwand möglich ist. Überdies sind mehrere, diskontinuierliche Arbeitsschritte erforderlich, die in verschiedenen Richtungen und Ebenen durchzuführen sind.The formation of the rod-like stacks is with these Devices for the division of the chains receiving the stack bound, d. H. also that a change in stack length only limited and possible with a relatively high workload is. Furthermore, there are several, discontinuous work steps required in different directions and levels are to be carried out.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art zu schaffen, die wenig Raum beansprucht und mit der die in Schuppenströmen zugeführten Druckbogen unterbrechungsfrei in Stapel überführt werden können.The invention has for its object a device of the type mentioned at the beginning to create little space claimed and with which the supplied in scale streams Printing sheets can be transferred in batches without interruption.

Erfindungsgemäß wird diese Aufgabe durch das Kennzeichen des Patentanspruchs 1 gelöst. Vorteilhafte weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.According to the invention, this object is achieved by the indicator of claim 1 solved. Advantageous further developments result from the subclaims.

Fig. 1 zeigt die erfindungsgemäße Einrichtung 1 zur Bildung eines sich senkrecht zu den stehend aneinandergereihten Druckbogen erstreckenden Stapels.Fig. 1 shows the inventive device 1 for education one perpendicular to the one lined up Sheet extending stack.

Die Druckbogen werden beim vorliegenden Beispiel über eine Fördervorrichtung 2, nachdem sie zuvor zentriert bzw. ausgerichtet und anschließend der vorhandene Falz nachgepreßt worden sind, in Form eines Schuppenstromes oder von sich folgenden Teilschuppenströmen, welche die Länge des herzustellenden Stapels bestimmen, in etwa senkrechter Richtung von oben einer horizontalen Stapelauflage 3 zugeführt. Dabei werden die Druckbogen bei mehrblättriger Ausführung mit dem Falz voraus auf der Stapelauflage 3 etwa senkrecht abgesetzt und an einem sich am Ende der Fördereinrichtung 2 befindenden, verschiebbaren Tragwerk 4, welches eine das vordere Ende des Stapels bildende Endplatte 5 trägt, auf der Stapelauflage 3 stapelbildend aufgestaut, wobei das Tragwerk 4 an einer sich entlang der Stapelauflage 3 parallel erstreckenden Führungsanordnung 6 mit der Geschwindigkeit des Stapelaufbaus angetrieben ist. In Fig. 2 ist auf diese Situation hingewiesen.The printed sheets are over in the present example a conveyor device 2 after it has been centered or aligned and then pressed the existing fold have been in the form of a stream of shingles or of the following Partial scale flows, which are the length of the to be produced Determine the stack, approximately in the vertical direction from fed to a horizontal stacking support 3 above. In doing so the printed sheets in the case of multi-sheet design with the fold set down on the stacking support 3 approximately vertically and at a located at the end of the conveyor 2 Slidable structure 4, which is a the front end of the End plate 5 forming stack supports on the stack support 3 piled up to form a stack, with the supporting structure 4 itself along the stack support 3 extending parallel guide arrangement 6 driven at the speed of stacking is. This situation is indicated in FIG. 2.

Eine neben dem Förderende der Fördervorrichtung 2 außerhalb der wirksamen stapelauflage 3 aktivierbare Trennvorrichtung 8 wird zwischen zwei der zugeführten Druckbogen eingelegt, sobald sich der vordere der beiden bestimmten Druckbogen wenigstens annähernd auf der Stapelauflage 3 befindet. Dieser Vorgang erfolgt durch ein Versetzen der Trennvorrichtung 8 in Richtung der Stapelbildung und kann hinsichtlich Zuverlässigkeit begünstigt werden, wenn vor dem Förderende der Fördervorrichtung 2 der Schuppenstrom durch eine Lückenbildungsvorrichtung in Teilschuppenströme unterbrochen wird oder zwischen zwei Druckbogen der Abstand vergrößert wird.One next to the conveying end of the conveying device 2 outside the effective stacking pad 3 separable device 8 is inserted between two of the printed sheets fed, once the front of the two specific printed sheets is at least approximately on the stack support 3. This is done by moving the separator 8 in the direction of stacking and can regarding Reliability will be favored if before the end of funding the conveyor device 2 the scale flow through a gap formation device is interrupted in partial scale flows or the distance between two printed sheets is increased.

D. h. es ist zu beachten, daß das Maß der die Stapelauflage 3 überstehenden Trennelemente 9 geringer ist als der Schuppenabstand zweier Druckbogen.That is, It should be noted that the dimension of the stacking pad 3 protruding separating elements 9 is less than that Scale spacing between two printed sheets.

Die Trennvorrichtung 8 ist paarweise mit Abstand quer zur Richtung der Stapelbildung angeordnet, und jede Trennvorrichtung 8 weist wiederum zwei aus einem Trenn- 9 und einem Stützelement 10 gebildete Teilpaare auf, die längs der Stapelauflage sich spiegelbildlich gegenüberliegend angeordnet sind.The separator 8 is transverse in pairs at a distance arranged to the direction of stacking, and each separator 8 in turn has two from a separator 9 and one Support element 10 formed part pairs, which along the stack support arranged opposite each other in mirror image are.

Das Einlegen der Trennvorrichtung 8 zwischen zwei Druckbogen erfolgt mit aneinander anliegenden Teilpaaren und hochgestellten Trennelementen 9, worauf wenigstens im unteren Bereich der gestapelten Druckbogen die Bildung einzelner Stapel entsteht.Inserting the separator 8 between two printed sheets takes place with adjoining partial pairs and superscript Separating elements 9, at least in the lower area the stacked printed sheets the formation of individual stacks arises.

Im Verlauf der weiteren Stapelbildung werden die Trennelemente 9 einen größeren Spalt in dem Stapel 7 bildend voneinander entfernt. Daraufhin werden die die Trennelemente 9 begleitenden Stützelemente 10 in den Spalt eingefahren, so weit, daß sie das entstehende hintere Ende des vorauslaufenden, von dem vorderen Ende des folgenden Stapels 7 stützend trennen können. Fig. 3 zeigt die Trenn- 9 und Stützelemente 10 (hilfsweise) seitlich versetzt, obschon sie quer zur Stapelbewegungsrichtung etwa fluchtend angeordnet sind.The separating elements become in the course of the further stack formation 9 forming a larger gap in the stack 7 from each other away. Thereupon the separating elements 9 accompanying support elements 10 retracted into the gap, so far that the emerging rear end of the leading, supporting from the front end of the following stack 7 can separate. Fig. 3 shows the separating 9 and support elements 10 (alternatively) laterally offset, although it is transverse to the direction of stack movement are arranged approximately in alignment.

Bei ausgestoßenen Stützelementen 10 werden die Trennelemente 9 aus dem Stapel 7 zurückgezogen, wie dies in Fig. 4 veranschaulicht ist. Während die hinteren Stützelemente 10 das vordere Ende eines sich erneut bildenden Stapels begrenzen, folgen die vorderen Stützelemente 10 an der Rückseite des vollständigen Stapels 7.When support elements 10 are ejected, the separating elements become 9 withdrawn from the stack 7, as shown in FIG. 4 is illustrated. While the rear support members 10 delimit the front end of a re-forming stack, the front support elements 10 follow at the rear the complete batch 7.

Wie Fig. 1 veranschaulicht, kann die Stapelauflage 3 wenigstens im vorderen Bereich des Stapelbildungsabschnittes durch in Stapelbildungsrichtung endlos angetriebene Bänder 45 ausgebildet sein, so daß eine wahlweise Vorverdichtung des Stapels 7 erzielt werden kann.As illustrated in FIG. 1, the stacking support 3 can at least in the front area of the stacking section by belts 45 driven endlessly in the stack formation direction be designed so that an optional pre-compression of the Stack 7 can be achieved.

Der Antrieb der Bänder 45 kann sowohl unabhängig wie auch abhängig von der Stapelbildungsgeschwindigkeit erfolgen.The drive of the belts 45 can be both independent and also take place depending on the stack formation speed.

Nach einer auf der Stapelauflage 3 zurückgelegten Wegstrecke wird mit einem weiteren Tragwerk 11, das ebenso wie Tragwerk 4 auf der Führungsanordnung 6 verschoben wird, eine das hintere Ende des vorauslaufenden Stapels 7 bildende Endplatte 12 aus einem seitlichen Magazin 13 gehoben und hinter den Stapel 7 etwa an den Stützelementen 10 anlehnend eingebaut. Sodann können die Stützelemente 10 unterhalb die Stapelauflage 3 abgesenkt werden, worauf der Stapel 7 mit der Rückseite an der Endplatte 12 anliegt. In Fig. 4 ist das vorläufige Anheben der Endplatte 12 aus einem Plattenmagazin 13 auf etwa die Höhe der Stapelauflage 3 dargestellt.After a distance traveled on the stack support 3 is with a further structure 11, which as well Structure 4 is moved on the guide assembly 6, a end plate forming the rear end of the leading stack 7 12 lifted from a side magazine 13 and behind the stack 7 installed approximately leaning against the support elements 10. Then the support elements 10 below the stack support 3 are lowered, whereupon the stack 7 with the Back rests on the end plate 12. 4 is the preliminary one Lifting the end plate 12 out of a plate magazine 13 shown at about the height of the stack support 3.

In der Zwischenzeit wird nach einem Weitertransport der Stapel 7 durch die ihn transportierenden Tragwerke 4 und 11 auf der Stapelauflage 3 zusammengepreßt und anschließend in einer am Ende der Stapelauflage 3 angeordneten Umreifungsvorrichtung 14 abgebunden (siehe Fig. 1).In the meantime the Stack 7 through the structures 4 and 11 transporting it pressed together on the stack support 3 and then in a strapping device arranged at the end of the stacking support 3 14 tied (see Fig. 1).

Der gebundene Stapel 7 wird sodann mit Hilfe der Tragwerke 4 und 11 auf eine seitliche Transportvorrichtung versetzt.The bound stack 7 is then using the structures 4 and 11 placed on a lateral transport device.

Anschließend werden die Tragwerke 4 und 11 an der Führungsanordnung 6 in den Bereich eines neuerlich anwachsenden Teilstapels zurückverschoben.
