Abstract

The invention relates to a device for changing a pile of sheets 11 formed on a transport element in a sheet delivering device with continuous sheet-feeding. In order to separate the pile into a lower part pile for dispatching and an upper, smaller part pile, two slides 17, 20 are provided, of which the first slide, as edge slide, has a cutter 22 which is directed towards a vertical front edge 23 of the pile 11, this cutter releasing a jet of air which lifts up the corner of the pile and forms a gap for the guiding in of said edge slide 20. With further advancing of the edge slide, the smaller pile is separated over its entire width from the remainder of the pile, so that the second slide 17, which is designed as a flat slide, can be pushed in perpendicularly with respect to the direction of advance of the edge slide 20. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Wechseln eines auf einem Transportelement gebildeten Bogenstapels in einem Bogenausleger mit fortlaufender Bogenzuführung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for changing a stack of sheets formed on a transport element in a sheet delivery with continuous sheet feed according to the preamble of claim 1.

Die Steigerung der Druckgeschwindigkeit in Rollenoffset-Maschinen und das Schneiden einer Materialbahn in Bogen auch halben Formates des Druckwalzenmantels macht für die Bedienungsmannschaft der Druckmaschine einen so häufigen Stapelwechsel mit manueller Hilfe erforderlich, daß dadurch die fortlaufende Überwachung der Druckmaschine beeinträchtigt wird.The increase in printing speed in web-fed offset presses and the cutting of a material web into sheets of half the format of the printing roller jacket make it so necessary for the operating team of the printing press to change the stack so often with manual help that the continuous monitoring of the printing press is thereby impaired.

So ist bei einem bekannten gattungsgemäßen Bogenausleger (DE-AS 27 51 489) ein dreieckiger und ein rechteckiger Schieber vorgesehen, die nacheinander von Hand zur Trennung eines oberen Teils des Stapels von dessen Stirnseite aus eingeschoben werden. Dabei wird von Hand eine Fuge für die Spitze des zuerst einzuschiebenden Dreieckschiebers gebildet, so daß dessen Einschub erleichtert wird und keine Bogenvorderkanten beschädigt werden.Thus, in a known generic sheet delivery (DE-AS 27 51 489) a triangular and a rectangular slide are provided, which are inserted one after the other by hand to separate an upper part of the stack from its end face. In this case, a joint is formed by hand for the tip of the triangular slide to be inserted first, so that its insertion is facilitated and no leading edges of the bow are damaged.

Zur Trennung von Teillagen aus einem ruhenden Stapel ist es bekannt (DE-OS 36 19 676), an einer Kante des Stapels eine Durchblättereinrichtung anzuordnen, die bei Erreichen einer Teillage eine Lücke an der Kante bildet, die das Einführen von Trennköpfen erleichtert. Diese Trennköpfe sind auf Schlitten angeordnet und können längs der Stirnseite verfahren werden. Mittels dieser Trennköpfe kann nach deren Verfahren der von ihnen erfaßte Teilstapel gegenüber dem darunter befindlichen Stapel verschoben werden. Ein Stapelwechsel ohne Unterbrechung der Ablage der Bögen ist bei diesem Stand der Technik nicht möglich.To separate partial layers from a stationary stack, it is known (DE-OS 36 19 676) to arrange a leafing device on one edge of the stack, which forms a gap at the edge when a partial layer is reached, which facilitates the insertion of separating heads. These cutting heads are arranged on slides and can be moved along the front. By means of these separating heads, the partial stack detected by them can be displaced relative to the stack located below. A stack change without interrupting the storage of the sheets is not possible with this prior art.

Schließlich ist eine Vorrichtung zum Wechseln eines Stapels in einem Bogenausleger bekannt (DE-OS 29 42 965), die aus einem Rechen besteht, der in Förderrichtung der Bogen zwischen der Stapeloberseite und den sich darauf ablegenden Bogen eingefahren werden kann. Damit dieser Vorgang ohne Beschädigung der Bogen durchgeführt werden kann, weist der Rechen an seinen Vorderseiten Blasdüsen auf. Eine solche Vorrichtung ist aber zur Trennung von bereits gestapelten Bogen schon deshalb nicht geeignet, weil die einzelnen Zinken des Rechens keine Gewähr dafür geben, daß sie zwischen den gleichen Bogen eingeführt werden. Auch lassen sich die Zinken nicht stirnseitig beschädigungsfrei in den Stapel einführen. Die aus den Zinken austretenden Luftstrahlen sind nicht in der Lage, eine definierte Lücke zwischen zwei gleichen Bogen auf der gesamten Stirnseite zu bilden.Finally, a device for changing a stack in a sheet delivery is known (DE-OS 29 42 965), which consists of a rake that can be inserted in the conveying direction of the sheet between the top of the stack and the sheet lying thereon. So that this process can be carried out without damaging the sheets, the rake has blow nozzles on its front sides. However, such a device is not suitable for separating sheets that have already been stacked, because the individual tines on the rake do not guarantee that they will be inserted between the same sheets. The tines cannot be inserted into the stack without damage on the end face. The air jets emerging from the tines are unable to form a defined gap between two identical arches on the entire end face.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Wechseln eines auf Transportelementen gebildeten Bogenstapels in einem Bogenausleger zu schaffen, mit der ein Stapelwechsel ohne manuelle Hilfe schnell und ohne Beschädigungsgefahr für die Bogen durchgeführt werden kann.The invention has for its object to provide a device for changing a sheet stack formed on transport elements in a sheet delivery, with which a stack change can be carried out quickly without manual help and without risk of damage to the sheets.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. In den Unteransprüchen sind vorteilhafte Ausgestaltungen dieser Lösung gekennzeichnet.This object is achieved in a device of the type mentioned by the characterizing features of claim 1. Advantageous embodiments of this solution are characterized in the subclaims.

Bei der erfindungsgemäßen Vorrichtung ist eine sichere Trennung innerhalb eines Bogenstapels gegeben, weil die Trennung nicht in der Mitte der Vorderkante des Stapels, sondern an einer Ecke des Stapels mit Unterstützung von Luft beginnt. An einer solchen Ecke ist der Stapel noch leicht anzuheben. Die luftgeschmierte, an einer Kante ansetzende Schneide bringt gegenüber einer dreieckigen, mittig an der Vorderkante des Stapels angesetzten Schneide eine größere Funktionssicherheit.In the device according to the invention there is a safe separation within a stack of sheets, because the separation does not begin in the middle of the front edge of the stack, but at a corner of the stack with the aid of air. The stack can still be lifted slightly at such a corner. The air-lubricated cutting edge attached to one edge provides greater functional reliability compared to a triangular cutting edge attached centrally to the front edge of the stack.

Im folgenden wird die Erfindung anhand einer Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Im einzelnen zeigen:

  • Figur 1 einen Bogenableger mit Querschneider im Vertikalschnitt,
  • Figur 2 den Bogenableger gemäß Figur 1 in Aufsicht an der Förderebene,

  • Figur 10 einen Bogenausleger mit einer zur Figur 1 alternativen Ablage.
The invention is explained in more detail below with reference to a drawing which shows exemplary embodiments. In detail show:
  • FIG. 1 shows a sheet stacker with cross cutter in vertical section,
  • FIG. 2 shows the sheet depositer according to FIG. 1 in supervision on the conveying plane,
  • FIG. 3 shows a corner of a stack formed in the sheet delivery 1 in the initial phase of the separation of the stack in an enlarged view,
  • FIG. 4 shows the corner of the stack according to FIG. 3 in section along line R - S of FIG. 3,

Gemäß dem Ausführungsbeispiel der Figur 1 wird die Materialbahn 1 durch einen Querschneider mit Obermesserwalze 2 und Untermesserbalken 3 in Bogen unterteilt, die über einen Schwebetisch 4 einem Bogenausleger zugeführt werden. Der Bogenausleger umfaßt eine Förderwalze 5, Förderrollen 6, Nockenscheiben 7, Saugtisch 8 zum Überlappen und Bremsen sowie eine Schwebedecke 9, unter der die Bogen bis zum Vorderkantenanschlag 10 geführt werden, wo sie einen fortlaufenden, höher werdenden Stapel 11 auf einer in der Höhe steuerbaren Palette 12 bilden. Außerhalb der Bogenflucht ist an einer Säule 13 eine Hülse 14 mit gewinkeltem Tragarm 15, an dessen abgewinkeltem Teil in beidseitigen Teleskopführungen 16 ein Flächenschieber 17 gelagert ist. Auf der Hülse 14 steht eine weitere nicht schwenkbare Hülse 18 mit einem einfachen Arm 19, der eine Teleskopführung für den Vorderkantenschieber 20 hat.According to the exemplary embodiment in FIG. 1, the material web 1 is divided into sheets by a cross cutter with an upper cutter roller 2 and a lower cutter bar 3, which are fed to a sheet delivery unit via a suspension table 4. The sheet delivery comprises a conveyor roller 5, conveyor rollers 6, cam disks 7, suction table 8 for overlapping and braking, and a floating ceiling 9, under which the sheets are guided up to the leading edge stop 10, where they are a continuously increasing stack 11 on a controllable height Form pallet 12. Outside the flight of arcs is on a column 13, a sleeve 14 with an angled support arm 15, at its angled part in a flat slide 17 is mounted on both sides of the telescopic guides 16. On the sleeve 14 is another non-pivotable sleeve 18 with a simple arm 19 which has a telescopic guide for the leading edge slide 20.

Nach Figur 20 wird der Flächenschieber 17 durch eine Schwenkbewegung A des Tragarms 15 um die Säule 13 in die gezeichnete Arbeitsstellung gebracht, die der Kantenschieber 20 entsprechend durch einen kleinen Hub B erreicht.According to FIG. 20, the surface slide 17 is brought into the drawn working position by a pivoting movement A of the support arm 15 around the column 13, which the edge slide 20 accordingly achieves through a small stroke B.

Der Stapelwechsel wird durch den Hub C des Kantenschiebers 20 eingeleitet. Das dafür nötige sichere Trennen wird durch Luftschmierung erreicht. Ober- und unterhalb des Kantenschiebers 20 sind stationär Luftdüsen 21 angeordnet, die auf die schräge Schneide 22 des Kantenschiebers 20 blasen und mit einem sich bildenden Flachstrahl gegen die senkrechte Stapelkante 23 einen kleinen oberen Teil des Stapels 11 als Bogenpaket örtlich anheben.The stack change is initiated by the stroke C of the edge pusher 20. The necessary safe separation is achieved by air lubrication. Above and below the edge pusher 20 there are stationary air nozzles 21 which blow onto the oblique cutting edge 22 of the edge pusher 20 and locally raise a small upper part of the stack 11 as a sheet package with a flat jet that forms against the vertical stacking edge 23.

Figur 4 zeigt aus der Sicht RS der Figur 3, wie durch zwei Rundstrahlen aus den Düsen 21 vor der Messerschneide 22 der Flachstrahl gebildet wird, der der senkrechten Stapelkante 23 ein kleines Bogenpaket 24 anhebt.FIG. 4 shows from the view RS of FIG. 3 how two round jets from the nozzles 21 in front of the knife edge 22 form the flat jet, which lifts a small sheet packet 24 from the vertical stacking edge 23.

Der Kantenschieber 20 kann nun leicht durch den genannten Hub C ein kleines Bogenpaket 24 abtrennen (Figuren 5 und 6).The edge pusher 20 can now easily separate a small sheet package 24 by the stroke C mentioned (FIGS. 5 and 6).

Der Stapel 11 wird etwas abgesenkt, wordurch eine Lücke D entsteht (Figur 7).The stack 11 is lowered somewhat, which creates a gap D (FIG. 7).

Der Flächenschieber 17 wird um die Bogenlänge E eingeschoben (Figur 8).The surface slide 17 is inserted by the arc length E (Figure 8).

Die Palette 12 mit dem von ihr getragenen Stapel 11 wird bis zum Boden 25 um das Maß F abgesenkt, und eine neue Palette 12a wird um das Maß G in die Position, die die volle Palette 12 dabei verläßt, geschoben (Figur 9).The pallet 12 with the stack 11 carried by it is lowered to the bottom 25 by the dimension F, and a new pallet 12a is pushed by the dimension G into the position which the full pallet 12 leaves in the process (FIG. 9).

Die neue Palette 12a wird mit dem Hub 1 unter den Flächenschieber 17 gebracht.The new pallet 12a is brought under the surface slide 17 with the stroke 1.

Die Hubbewegungen werden in umgekehrter Reihenfolge E,D,C,B,A ausgeführt, wodurch der Stapelwechsel beendet ist und der volle Stapel 11 auf der Palette 12 abtransportiert werden kann.The lifting movements are carried out in reverse order E, D, C, B, A, whereby the stack change is finished and the full stack 11 can be removed on the pallet 12.

Figur 5 zeigt, wie an der Vorderkante des Flächenschiebers 17 Kegeldüsen 26, z.B. nach DE-OS 39 36 846, eingelassen sind und ein Luftpolster in den Spalt zwischen Bogenpaket 24 und Stapel 11 blasen. Diese Düsen sind in zwei versetzten Reihen auf der Ober- und Unterseite des Flächenschiebers 17 angeordnet (Figur 3).Fig. 5 shows how cone nozzles 26, e.g. according to DE-OS 39 36 846, are let in and blow an air cushion into the gap between sheet package 24 and stack 11. These nozzles are arranged in two staggered rows on the top and bottom of the surface slide 17 (Figure 3).

Anstelle eines Palettenbetriebes kann der Stapel 11 auch auf einem heb- und senkbaren Bandertisch 27 gebildet, getrennt und abgeführt werden, wobei die Höhe des Stapels 11 der Weiterverarbeitung angepaßt ist, z.B. dem Handhabungstransport auf Luftkissentischen 28.Instead of a pallet operation, the stack 11 can also be formed, separated and removed on a lifting and lowering conveyor table 27, the height of the stack 11 being adapted to further processing, e.g. handling transport on air cushion tables 28.

Die Figuren 1 und 2 zeigen den Flächenschieber in Schubrichtung mit der Förderrichtung übereinstimmend. Bei zweibahnigem Betrieb haben zwei Kantenschieber jeweils die Außenseiten der beiden Stapel mit Schubrichtung gegen die Förderrichtung, während zwei Flächenschieber senkrecht zur Förderrichtung von außen unter die Kantenschieber vordringend die beiden oberen Teile des Stapels für die Dauer der Stapelabfuhr halten. Die Schieber sind mit Teleskopführungen an Armen versehen, die an Hülsen befestigt sind. Die Hülsen sind wie für Paletten bekannt, auch mit einer Absenkautomatik versehen. Die Stapel können so ohne manuellen Eingriff gebildet, gewechselt und abgefördert werden.Figures 1 and 2 show the surface slide in the direction of the thrust coinciding with the conveying direction. In two-lane operation, two edge slides each have the outer sides of the two stacks with a direction of thrust against the conveying direction, while two surface slides, perpendicular to the conveying direction, penetrate from below under the edge sliders to hold the two upper parts of the stack for the duration of the stack removal. The sliders are equipped with telescopic guides on arms that are attached to sleeves. As is known for pallets, the sleeves are also provided with an automatic lowering mechanism. The stacks can be formed, exchanged and removed without manual intervention.
