Abstract

The storage device is for a printing press. The material can be supplied to form a stack. There are stops for the front edges and successive side stops consisting of connected stop sectors, one of which is fixed and the other (3.2) can be varied in length. The fixed stop sector has a fixed first link and a second link. These links form application points for the variable-length stop sector and are coupled to a series of sprung double stops (19-22). When the variable-length sector moves, the turning links (24-26) of the double stops can be moved horizontally by the first link.

Description

Die Erfindung betrifft eine Auslegevorrichtung für bogenförmige Bedruckstoffe an einer Druckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to a delivery device for sheet-shaped substrates a printing press according to the preamble of the main claim.

Eine Vorrichtung dieser Art ist aus der DE 41 39 978 C1 bekannt und dient der Stapelung bogenförmiger Bedruckstoffe im Ausleger einer Druckmaschine. Neben Vorderkantenanschlägen weist die Vorrichtung zur Formatbreitenanpassung seitlich verstellbare und in ihrer wirksamen Länge an die Formatlänge anpaßbare Seitenanschläge auf. Die Seitenanschläge sind dabei durch einen ersten, vorzugsweise fest angeordneten Gehäuseteil gebildet, in den teleskopisch ineinander ein zweiter Gehäuseteil verschiebbar bzw. aus diesem herausziehbar ist. Die Seitenanschläge sind in Längsrichtung durch Abschnitte gebildet, die beidseitig in einer mehrteiligen Führung teleskopisch in Verbindung mit den Gehäuseteilen ineinander schiebbar geführt sind, wobei nicht benötigte Abschnitte in einer Schleppschlaufe umlenkbar sind.
Nachteilig ist bei diesen Ausführungen, daß in Folge der nicht benötigten Abschnitte sowie deren Umlenkung die maximal zu verarbeitende Formatbreite an einer Druckmaschine eingeschränkt ist. Weiterhin ist zur Reduzierung von Luftpolstern im oberen Teil des Bogenstapels eine zusätzliche Luftabsaugung notwendig.A device of this type is known from DE 41 39 978 C1 and is used for stacking sheet-shaped printing materials in the delivery of a printing press. In addition to front edge stops, the device for adjusting the format width has laterally adjustable side stops which can be adjusted in their effective length to the format length. The side stops are formed by a first, preferably fixedly arranged housing part, into which a second housing part can be telescopically slid into or pulled out of one another. The side stops are formed in the longitudinal direction by sections which are telescopically guided on both sides in a multi-part guide in connection with the housing parts, sections which are not required being deflectable in a drag loop.
A disadvantage of these designs is that, as a result of the sections that are not required and their deflection, the maximum format width to be processed on a printing press is restricted. Additional air extraction is also required to reduce air pockets in the upper part of the sheet stack.

Gemäß der DE 37 10 329 C2 ist eine Vorrichtung in einem Bogenausleger einer Druckmaschine bekannt, die pneumatisch erregte, schwingfähige Seitenanschläge aufweist. Mittels Druckluft wird eine Luftkammer beaufschlagt, welche einen Membranbolzen aktiviert. Der Membranbolzen ist mit einem Stellbolzen gekoppelt, der über eine Kugelpfanne eine über eine Zugfeder belastete Stoßplatte der Seitenanschläge erregt. Die Seitenanschläge sind an gestellfesten Schienen angeordnet und sind längs dieser verschiebbar. Seitenanschläge dieser Art berücksichtigen nicht die volle Länge eines Bogens bei entsprechendem Format. Dies fördert das schräge Ablegen von Bogen, was sich wiederum auf die Stapelbildung und Weiterverarbeitung negativ auswirkt.According to DE 37 10 329 C2, a device in a sheet delivery is one Printing machine known, the pneumatically excited, swinging side stops having. By means of compressed air, an air chamber is applied, which holds a membrane bolt activated. The membrane bolt is coupled to an adjusting bolt that via a ball socket a push plate of the side stops loaded by a tension spring excited. The side stops are arranged on rails fixed to the frame and can be moved along this. Consider side stops of this type not the full length of a sheet with the appropriate format. This promotes that slanting sheets, which in turn affects stacking and finishing has a negative impact.

Der Erfindung liegt die Aufgabe zugrunde, eine Auslegevorrichtung für bogenförmige Bedruckstoffe an einer Druckmaschine zu schaffen, die die genannten Nachteile vermeidet, die insbesondere - abhängig vom Längs- und Querformateine Anpassung der Seitenanschläge gestattet bei voller Ausnutzung der maximalen Formatbreite der verarbeitenden Bedruckstoffe.The invention has for its object a delivery device for arcuate To create substrates on a printing press, the above Avoids disadvantages, in particular - depending on the longitudinal and landscape format Adjustment of the side stops allowed with full use of the maximum Format width of the processing substrates.

Gelöst wird die Aufgabe durch die Ausbildungsmerkmale des Hauptanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen.The task is solved by the training features of the main claim. Further training results from the subclaims.

Bekanntlich sind Seitenanschläge für die Stapelbildung bogenförmiger Bedruckstoffe in der Auslegevorrichtung beidseitig in Seitengestellen gelagert.
Ein Seitenkantenanschlag, welcher auch die Funktion eines Geradstoßers (Bogenschiebers) ausüben kann, ist im Wesentlichen durch zwei Abschnitte ausgebildet. Der erste Abschnitt ist in Längsrichtung feststehend und der zweite Abschnitt ist in Längsrichtung durch übereinanderschiebbare Getriebeglieder in Form von Zweischlägen ausgebildet. Die Zweischläge sind mittels Drehgelenken an dem längsseitig feststehenden ersten Abschnitt der Seitenkantenanschläge angeordnet. Der feststehende erste Abschnitt eines Seitenkantenanschlages ist weiterhin mit einem auf den Auslegerstapel einwirkenden Schwingantrieb gekoppelt. Die Lagerung der Drehgelenke der Zweischläge ist schmutzunempfindlich, wobei zusätzlich eine Kapselung möglich ist. Neben den Öffnungen aufweisenden feststehenden Abschnitten der Seitenanschläge gestatten die Zwischenräume zwischen den Zweischlägen des übereinanderschiebbaren zweiten Abschnittes ein Entweichen der Luft, insbesondere aus dem oberen Auslegerstapelbereich. Zusätzliche Luftabsaugungen sind daher nicht erforderlich.
Die hintereinander geschalteten Zweischläge sind federbelastet und sind mit einer formatabhängig verschiebbaren Bogenbremseinrichtung in Längsrichtung übereinanderschiebbar angeordnet.As is known, side stops for stacking sheet-shaped printing materials are stored on both sides in side frames in the delivery device.
A side edge stop, which can also act as a straight pusher (arc pusher), is essentially formed by two sections. The first section is fixed in the longitudinal direction and the second section is formed in the longitudinal direction by sliding gear elements in the form of two strikes. The two blows are arranged by means of swivel joints on the first section of the side edge stops which is fixed on the longitudinal side. The fixed first section of a side edge stop is also coupled to an oscillating drive acting on the boom stack. The bearings of the swivel joints of the two strikes are insensitive to dirt, whereby encapsulation is also possible. In addition to the fixed sections of the side stops which have openings, the spaces between the two flaps of the second section which can be pushed one over the other allow the air to escape, in particular from the upper jib stack area. Additional air extraction is therefore not necessary.
The series-connected two strokes are spring-loaded and are arranged to be slidable one above the other in the longitudinal direction with a format-dependent sliding sheet braking device.

Die Zweischläge werden von einer in Förderrichtung der Bedruckstoffe vorgeordneten Bogenbremseinrichtung bzw. deren Traverse bei Formatverstellung in Förderrichtung auf den feststehenden, ersten Abschnitt zu übereinandergeschoben bis zum Erreichen eines Minimalformates. Bei Maximalformat wird die Bogenbremseinrichtung mittels, vorzugsweise von einer zentralen Steuerung aktivierten, Antriebsmitteln entgegen der Förderrichtung angepaßt. Dazu werden die Zweischläge durch die Federbelastung entgegen der Förderrichtung gespreizt. Im Verstellbereich zwischen Minimal- bzw. Maximalformat sind selbstverständlich auch Einstellungen auf Zwischenformate möglich. Ein Seitenanschlag deckt somit mit dem feststehenden ersten Abschnitt und dem übereinanderschiebbaren zweiten Abschnitt im Wesentlichen die volle Länge eines Auslegerstapels ab. Die durch unterschiedliche Bremsleistung der Bogenbremseinrichtung und/oder unterschiedliches Sujet bedingte Schräglage der abgelegten Bogen wird beseitigt. Die Stapelbildung wird spürbar verbessert und rein optisch ist eine exakte Stapelkante erkennbar. Der übereinanderschiebbare zweite Teil benötigt gegenüber dem feststehenden Abschnitt im Querformat keinen zusätzlichen Bauraum. Dadurch ist wird eine Einschränkung des maximalen Querformates ausgeschlossen.The two strokes are arranged upstream from one of the substrates in the conveying direction Sheet brake device or its traverse with format adjustment in the conveying direction pushed onto the fixed, first section until a minimal format is reached. At maximum format, the sheet brake device by means of, preferably activated by a central control, Drive means adapted against the direction of conveyance. This will be the two strokes spread against the conveying direction by the spring load. In the adjustment area between minimum and maximum format are of course also Settings for intermediate formats possible. A side stop therefore also covers the fixed first section and the stackable second Section essentially the full length of a boom stack. By different braking performance of the sheet braking device and / or different The obliquity of the deposited sheets caused by the subject is eliminated. The Pile formation is noticeably improved and purely visually is an exact stack edge recognizable. The slidable second part requires compared to the fixed Section in landscape format no additional installation space. This is a restriction of the maximum landscape format excluded.

Darüber hinaus ist der feststehende Abschnitt des Seitenanschlages mit Mitteln für die Anpassung des Querformates gekoppelt. Die Mittel zum Anpassen des Querformates sowie des Längsformates sind vorzugsweise mit einer zentralen Steuerung , z.B. einem Leitstand, gekoppelt, so daß erforderliche Formatanpassungen automatisch durchführbar sind.In addition, the fixed section of the side stop with funds for the adjustment of the landscape format coupled. The means to adjust the landscape format and the longitudinal format are preferably with a central control , e.g. a control center, coupled, so that necessary format adjustments can be carried out automatically.

Eine Auslegevorrichtung 1 ist durch einen Auslegestapel 2 sowie eine Bogenbremseinrichtung 10 mit angeordneter Traverse 4, welche integrierte Hinterkantenanschläge 8, 9 aufweist, ausgebildet. Weiterhin sind beidseitig am Seitengestell gelagerte Seitenkantenanschläge 3 angeordnet. Die Auslegevorrichtung 1 besitzt weiterhin Vorderkantenanschläge, die aus Gründen der Übersichtlichkeit in Fig. 1 nicht dargestellt sind.
Ein Seitenkantenanschlag 3 ist in einer Lagerung 6 am jeweiligen Seitengestell drehbar aufgenommen und ist mit einem Schwingantrieb 7 gekoppelt, der die Seitenkantenanschläge 3 in einen Winkel 5 um die Drehachse der Lagerung 6 in Richtung Auslegestapel 2 elektrisch erregt. Die Schwingantrieb 7 ist, vorzugsweise von einer zentralen Steuerung aus, zu- bzw. abschaltbar. Für die Anpassung des Querformates ist die Lagerung 6 entsprechend bewegbar.A laying device 1 is formed by a laying stack 2 and a sheet braking device 10 with an arranged cross member 4, which has integrated trailing edge stops 8, 9. Furthermore, side edge stops 3 are arranged on both sides of the side frame. The laying device 1 also has front edge stops, which are not shown in FIG. 1 for reasons of clarity.
A side edge stop 3 is rotatably received in a bearing 6 on the respective side frame and is coupled to an oscillating drive 7 which electrically excites the side edge stops 3 at an angle 5 about the axis of rotation of the bearing 6 in the direction of the delivery stack 2. The oscillating drive 7 can be switched on or off, preferably from a central control. The bearing 6 can be moved accordingly for the adaptation of the landscape format.

Die Seitenkantenanschläge 3 sind gemäß Figur 3 durch eine in ihrer Größe definierte Platte als ein feststehender (erster) Abschnitt 3.1 gebildet. Der Abschnitt 3.1 weist Öffnungen zur Luftdurchströmung auf. Am Abschnitt 3.1 ist ein erstes Drehgelenk 12 sowie ein zweites Drehgelenk 13 als Anlenkpunkt für einen übereinander schiebbaren (zweiten) Abschnitt 3.2 angeordnet. Der übereinander schiebbare Abschnitt 3.2 ist durch eine mehrfache Hintereinanderschaltung von federbelasteten Zweischlägen 19, 20, 21, 22 gebildet, die an den Drehgelenken 12, 13 angeordnet sind. Das erste Drehgelenk 12 sowie nachgeschaltete freibewegliche Drehgelenke 24, 25, 26 der Zweischläge 19,20 sind auf einer horizontal verlaufenden Geraden 23 als Führungskurve bewegbar. Auf dieser Gerade 23 liegt ferner die Achse des Wälzkörpers 11 sowie die Achse der Lagerung 6. Damit schwingen die Abschnitte 3.1, 3. 2 bei aktiviertem Schwingantrieb 7 in einer Drehachse, die der Geraden 23 entspricht. According to FIG. 3, the side edge stops 3 are defined by a size Plate formed as a fixed (first) section 3.1. Section 3.1 has openings for air flow. At section 3.1 is a first swivel 12 and a second hinge 13 as a pivot point for one above the other sliding (second) section 3.2 arranged. The one that can be pushed over one another Section 3.2 is a multiple series connection of spring-loaded Two strikes 19, 20, 21, 22 formed, which are arranged on the rotary joints 12, 13 are. The first swivel joint 12 and downstream freely movable swivel joints 24, 25, 26 of the two strokes 19, 20 are on a horizontal Straight line 23 can be moved as a guide curve. On this straight line 23 is also the Axis of the rolling element 11 and the axis of the bearing 6 Sections 3.1, 3. 2 with activated vibratory drive 7 in an axis of rotation which the Straight line 23 corresponds.

In bevorzugter Ausbildung ist das zweite Drehgelenk 13 unter Zwischenschaltung einer Schwinge 14 mit dem ersten der nachgeschalteten Zweischläge 19, 20, 21, 22 (Abschnitt 3.2) über ein weiteres Drehgelenk gekoppelt. Alternativ kann die Schwinge 14 sowie das Drehgelenk 13 entfallen, wenn der erste der nachgeschalteten Zweischläge 19, 20, 21, 22 (Abschnitt 3.2) mit dem Abschnitt 3.1 über ein Dreh-Schub-Gelenk gekoppelt ist.In a preferred embodiment, the second swivel joint 13 is interposed a rocker 14 with the first of the two strikes 19, 20, 21 connected downstream, 22 (section 3.2) coupled via a further swivel joint. Alternatively, the Swing arm 14 and the hinge 13 are omitted if the first of the downstream Two strokes 19, 20, 21, 22 (section 3.2) with section 3.1 above Rotary-thrust joint is coupled.

An einem freien Ende der hintereinander geschalteten Zweischläge 19, 20, 21, 22 ist ein Wälzkörper 11 angeordnet, welcher unter Federspannung an einer Traverse 4 der Bogenbremseinrichtung 10 anliegt. Die Federspannung wird beispielsweise durch eine Zugfeder 27 erzeugt, die im vorliegenden Beispiel an einem Anlenkpunkt 16 der Lagerung 6 und einem Anlenkpunkt 15 an einem Getriebeglied des Zweischlages 19 fixiert ist. Damit stehen die hintereinandergeschalteten Zweischläge 19, 20, 21, 22 ständig unter Federspannung und haben das Bestreben sich zwischen Abschnitt 3.1 und Traverse 4 zu spreizen.
Der Wälzkörper 11 ist bei Anpassung des Seitenkantenanschlages 3 für das Querformat entlang der Traverse 4 bzw. den daran angeordneten Hinterkantenanschlägen 8, 9 verschiebbar. Bei einem durch den Schwingantrieb 7 erregtem Seitenkantenanschlag 3 ist der Wälzkörper 11 an der Traverse 4 um seinen Anlagepunkt schwenkbar.At a free end of the two-stroke units 19, 20, 21, 22 connected in series, a roller body 11 is arranged, which rests under spring tension on a crossbar 4 of the sheet braking device 10. The spring tension is generated, for example, by a tension spring 27, which in the present example is fixed to a pivot point 16 of the bearing 6 and a pivot point 15 to a gear member of the two-way stop 19. The series-connected two-blows 19, 20, 21, 22 are thus constantly under spring tension and have the tendency to spread between section 3.1 and crossbar 4.
The roller body 11 is displaceable when the side edge stop 3 is adapted for the landscape format along the cross member 4 or the rear edge stops 8, 9 arranged thereon. When the side edge stop 3 is excited by the oscillating drive 7, the roller body 11 can be pivoted on the cross member 4 about its contact point.

Die Wirkungsweise ist wie folgt: In an sich bekannter Weise werden an der Vorderkante gefaßte, bogenförmige Bedruckstoffe von Greifersystemen, welche an umlaufenden Kettensystemen angelenkt sind, in Förderrichtung 17 über die Bogenbremseinrichtung 10 geführt und auf dem Auslegerstapel 2 gegen Vorderkantenanschläge abgelegt. Dabei richtet sich der Bedruckstoff nach der Vorderkante selbsttätig aus. Die seitliche Ablage des Bedruckstoffes wird durch beidseitig am Auslegerstapel 2 benachbarte Seitenanschläge 3 beeinflußt, indem ein Schwingantrieb 7 wenigstens einen Seitenanschlag 3 erregt. Dabei führt der Seitenanschlag 3 im Bereich des Winkels 5 die Schwingbewegung in Richtung Auslegerstapel 2 aus.
Für die Seitenanschläge 3 sind verschiedene Betriebsweisen möglich. So kann ein Seitenanschlag 3 als Festanschlag stillgesetzt sein, wobei der gegenüberliegende Seitenanschlag 3 die Schwingbewegung ausführt.
Weiterhin sind die beide Seitenanschläge 3 jeweils mit einer Schwingbewegung erregbar. Dabei kann die Schwingbewegung gleichphasig durch die Schwingantriebe 7 erzeugt werden, wobei ein Seitenanschlag 3 auf den Auslegerstapel 2 zubewegt und der gegenüberliegende Seitenanschlag 3 vom Auslegerstapel 2 wegbewegt wird. Die Schwingbewegung wird dabei auf beide Abschnitte 3.1 und 3.2 übertragen.The mode of operation is as follows: In a manner known per se, sheet-like printing materials, gripped at the front edge, of gripper systems, which are articulated on circulating chain systems, are guided in the conveying direction 17 via the sheet braking device 10 and placed on the delivery stack 2 against front edge stops. The substrate automatically aligns itself with the leading edge. The lateral placement of the printing material is influenced by side stops 3 adjacent on both sides of the delivery stack 2, in that an oscillating drive 7 excites at least one side stop 3. The side stop 3 executes the swinging movement in the direction of the boom stack 2 in the area of the angle 5.
Different operating modes are possible for the side stops 3. Thus, a side stop 3 can be stopped as a fixed stop, the opposite side stop 3 carrying out the oscillating movement.
Furthermore, the two side stops 3 can each be excited with an oscillating movement. The oscillating movement can be generated in phase by the oscillating drives 7, one side stop 3 being moved towards the boom stack 2 and the opposite side stop 3 being moved away from the boom stack 2. The oscillating movement is transferred to both sections 3.1 and 3.2.

Für die exakte Stapelbildung wird jedoch bevorzugt die Schwingbewegung gegenphasig durch die Schwingantriebe 7 erzeugt, wobei beide Seitenanschläge 3 zugleich auf den Auslegerstapel 2 zubewegt und gemeinsam vom Auslegerstapel 2 wegbewegt werden.
Die Längsformatverstellung erfolgt durch Aktivierung eines Stellmotores, welcher getriebetechnisch gekoppelt auf zwei seitlich in den Seitengestellen gelagerte Gewindespindeln wirkt. Die Gewindespindeln tragen die Traverse 4 (einschl. Hinterkantenanschläge 8, 9) mit der Bogenbremseinrichtung 10. Für die Einstellung des Minimalformates wird die Bogenbremseinrichtung 10 mit der Traverse 4 in Förderrichtung 17 des Bedruckstoffes vor bewegt (Position 18). Die Traverse 4 schiebt bei dieser Vorbewegung, beginnend mit dem den Wälzkörper 11 tragenden Zweischlag 22, die Zweischläge 19, 20, 21, 22 (Abschnitt 3. 2) in Richtung auf den feststehenden Abschnitt 3. 1 übereinander.
Für die Einstellung eines Zwischenformates oder des Maximalformates wird die Bogenbremseinrichtung 10 mit der Traverse 4 entgegen der Förderrichtung 17 zurück bewegt (Position 18'). Dabei füllt der Abschnitt 3. 2 den frei werden Platz aus, indem die unter Belastung der Zugfeder 27 stehenden Zweischläge 19, 20, 21, 22 gestreckt werden. Der Wälzkörper 11 liegt ständig an der Traverse 4 bzw. an den Hinterkantenanschlägen 8, 9 an. For the exact stack formation, however, the oscillating movement is preferably generated in phase opposition by the oscillating drives 7, both side stops 3 being simultaneously moved towards the delivery stack 2 and being moved away from the delivery stack 2 together.
The longitudinal format is adjusted by activating a servomotor which, coupled with the gearbox, acts on two threaded spindles mounted on the side of the side frames. The threaded spindles carry the traverse 4 (including trailing edge stops 8, 9) with the sheet brake device 10. To set the minimum format, the sheet brake device 10 is moved with the cross member 4 in the conveying direction 17 of the printing material (position 18). During this forward movement, the traverse 4 pushes the two strikes 19, 20, 21, 22 (section 3.2) one above the other, starting with the two-stroke 22 supporting the rolling element 11, in the direction of the fixed section 3.1.
To set an intermediate format or the maximum format, the sheet braking device 10 is moved back with the cross member 4 against the conveying direction 17 (position 18 '). The section 3.2 fills the space which becomes free by stretching the two-strokes 19, 20, 21, 22 which are under load from the tension spring 27. The rolling element 11 is constantly in contact with the cross member 4 or the rear edge stops 8, 9.
