Abstract

The paper sheets leave the electrophotographic printing machine between upper and lower horizontal guide plates (13). They pass between pairs of transport rollers (10) and then move into pockets formed by direction changing rollers (1) with arcuate guide plates (3). The plates hold the edges of the sheets emerging from the printer and move them to the output stack (6). Additional guide rollers (11) push the paper sheets against disks (2) adjacent to the direction changing rollers. A guide sheet (4) adjacent to the paper stack pulls the sheets of paper out of the pockets, allowing them to be deposited on the stack.

Description

Die Erfindung betrifft ein Verfahren zum Transport eines im wesentlichen bogenförmigen Elementes, insbesondere zum Transport eines Bedruckstoffbogens in einer Druckmaschine, vorzugsweise in einer elektrofotographisch arbeitenden Druckmaschine, bei dem das bogenförmige Element durch wenigstens ein rotierendes Transportorgan an einer Erfassungsstelle in seinem Vorderkantenbereich erfaßt, bis zu einer Abgabestelle mitgenommen und dort abgegeben wird, wobei das bogenförmige Element während der Mitnahme über einen Rotations- oder Krümmungsradius gekrümmt wird, wobei das bogenförmige Element durch wenigstens ein wenigstens in Zentrifugalrichtung blockierendes Führungselement zwischen der Erfassungsstelle und der Abgabestelle zur Beibehaltung des Krümmungsradius gezwungen wird.The invention relates to a method for transporting a substantially arcuate element, in particular for transporting a printing material sheet in a printing press, preferably in an electrophotographic printing machine, wherein the arcuate element detected by at least one rotating transport member at a detection point in its leading edge region, up to a Transfer point is taken and delivered there, wherein the arcuate element is curved during the entrainment over a radius of curvature or rotation, wherein the arcuate element is forced by at least one at least in the centrifugal blocking guide member between the detection point and the delivery point to maintain the radius of curvature.

Des weiteren betrifft die Erfindung eine Vorrichtung zum Transport eines im wesentlichen bogenförmigen Elementes, insbesondere zum Transport eines Bedruckstoffbogens in einer Druckmaschine, vorzugsweise in einer elektrofotographisch arbeitenden Druckmaschine, umfassend wenigstens ein das bogenförmige Element von einer Erfassungsstelle bis zu einer Abgabestelle transportierendes und dort abgebendes, rotierendes Transportorgan, welches zur Erfassung und Mitnahme des bogenförmigen Elementes wenigstens eine maulartige Aufnahme zur Einführung bzw. Einsteckung des Vorderkantenbereiches des bogenförmigen Elementes aufweist und umfassend wenigstens einen wenigstens fragmentarisch vorhandenen Biegekern zur Krümmung des bogenförmigen Elementes während der Mitnahme über einen Rotations- oder Krümmungsradius, vorzugsweise zur Durchführung des vorgenannten Verfahrens, umfassend wenigstens ein wenigstens in Zentrifugalrichtung blockierendes Führungselement zwischen der Erfassungsstelle und der Abgabestelle zur erzwungenen Beibehaltung des Krümmungsradius.Furthermore, the invention relates to a device for transporting a substantially arcuate element, in particular for transporting a printing material sheet in a printing press, preferably in an electrophotographic printing machine, comprising at least one of the arcuate element from a detection point to a delivery point and there delivering, rotating Transport organ, which has for detecting and entrainment of the arcuate element at least one jaw-like receptacle for insertion or insertion of the leading edge region of the arcuate element and comprising at least one at least fragmentarily present bending core to the curvature of the arcuate element during driving over a radius of rotation or curvature, preferably for Carrying out the above-mentioned method, comprising at least one guide element blocking at least in the centrifugal direction between the detection point u nd the delivery point for forced retention of the radius of curvature.

Aus der US-A-5 261 655 ist eine Transportvorrichtung bekannt. Die dortige Vorrichtung umfaßt insbesondere ein rotierendes Transportorgan mit zwei maulartigen Aufnahmen, nämlich Schlitzen, in die jeweils die Vorderkante eines Bogens mittels Einfütterungsrollen im Bereich einer Erfassungsstelle eingeführt werden kann. Zudem sind in dem Bereich der Erfassungsstelle separate Wellrollen angeordnet, die den Bogen und insbesondere auch dessen Schwanzende in Querrichtung einwellen und versteifen, um bis in diesen Schwanzbereich hinein eine kontrollierte Transportbewegung des Bogens zu gewährleisten. Dabei sind die Wellrollen im Bereich der Erfassungsstelle so angeordnet, daß sie die Einfütterung durch die Einfütterungsrollen nicht behindern, auch dann nicht, wenn wie in der Druckschrift vorgesehen, der Radius des Transportorgans verändert wird. Dazu haben die Wellrollen einen radialen Abstand zur Rotationsachse des Transportorgans, der größer ist als der minimale Radius und kleiner ist als der maximale Radius des Transportorgans.From the US-A-5,261,655 a transport device is known. The local device comprises in particular a rotating transport member with two mouth-like receptacles, namely slots, in each of which the leading edge of a sheet can be introduced by means of Einfütterungsrollen in the region of a detection point. In addition, separate corrugated rolls are arranged in the region of the detection point, which wave in the transverse direction and stiffen the bow and in particular its tail in order to ensure a controlled transport movement of the sheet to this tail area. The corrugated rolls are arranged in the region of the detection point so that they do not hinder the feeding by the Einfütterungsrollen, not even if, as provided in the publication, the radius of the transport member is changed. For this purpose, the corrugated rollers have a radial distance to the axis of rotation of the transport member, which is greater than the minimum radius and is smaller than the maximum radius of the transport member.

Eine Druckmaschine, insbesondere eine elektrofotographisch arbeitende Druckmaschine, soll in der Lage sein, möglichst unterschiedlichen Bedruckstoff zu bedrucken, insbesondere Papier unterschiedlicher Bogenlänge und unterschiedlichen Papiergewichts zu bedrucken. Wenn ein besonders hohes Papiergewicht benutzt werden soll, ist es aufgrund der Steifigkeit des Papiers notwendig, dieses allenfalls über einen großen Krümmungsradius zu biegen, um bleibende Beschädigungen des Papiers zu vermeiden. Gleichzeitig läßt sich schweres Papier aber auch über einen großen Radius nur schwer biegen. Durch den größeren Radius wird aber auch der Krümmungsumfang bzw. -weg automatisch größer, also auch der Weg zwischen Erfassungsstelle und Abgabestelle. Besonders schlecht handhaben lassen sich somit kurze und gleichzeitig schwere Papiere. Zum Beispiel wäre es bei einem Papiergewicht von 300 Gramm pro Quadratmeter notwendig, einen Mindestkrümmungsradius von 90 mm vorzusehen. Dies führt aber zwangsläufig zu einer Krümmungslänge, die mindestens gleich der Längserstreckung eines DIN A4-Bogens ist. Querformate oder kleinere Formate können also über einen weiten Bereich des Transportweges aufgrund ihrer Steifigkeit die Krümmung aufheben, was den Transport insgesamt beeinträchtigt oder gefährdet. Zur Lösung dieses Problems reicht es nicht aus, das Einfädeln des Bogens im Bereich der Erfassungsrolle durch Wellrollen zu unterstützen, wie in der vorzitierten Druckschrift vorgeschlagen worden ist.A printing machine, in particular an electrophotographically operating printing press, should be able to print as different a substrate as possible, in particular to print paper of different sheet length and different paper weight. If a particularly high paper weight is to be used, it is necessary because of the stiffness of the paper to bend it at best over a large radius of curvature in order to avoid lasting damage to the paper. At the same time, heavy paper is difficult to bend over a large radius. Due to the larger radius but also the curvature circumference or path is automatically larger, including the path between detection point and delivery point. Thus, it is particularly difficult to handle short and at the same time heavy papers. For example, with a paper weight of 300 grams per square meter, it would be necessary to provide a minimum radius of curvature of 90 mm. However, this inevitably leads to a curvature length which is at least equal to the longitudinal extent of a DIN A4 sheet. Because of their rigidity, landscape formats or smaller formats can therefore cancel out the curvature over a wide range of the transport path, which impairs or endangers the transport as a whole. To solve this problem, it is not enough to thread of the sheet in the area of the detection roller to support by corrugated rolls, as has been proposed in the above-cited document.

Aus der US 5,261,655 ist zudem eine Transport- und Stapelvorrichtung der eingangs genannten Gattung bekannt.From the US 5,261,655 In addition, a transport and stacking device of the type mentioned is known.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren bzw. eine Vorrichtung der eingangs genannten Gattung aufzuzeigen, das bzw. die für unterschiedlichste Bögen bzw. bogenförmige Elemente geeignet ist.The invention is therefore based on the object of disclosing a method or a device of the type mentioned, which is suitable for a wide variety of sheets or arcuate elements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Länge bzw. Kürze des bogenförmigen Elementes durch Variation des über den Krümmungsweg des bogenförmigen Elementes gemessenen Abstandes zwischen dem Führungselement und der Abgabestelle Rechnung getragen wird, indem der über den Krümmungsweg des bogenförmigen Elementes gemessene Abstand zwischen dem Führungselement und der Abgabestelle zur Berücksichtigung der Länge bzw. Kürze des bogenförmigen Elementes variabel einstellbar ist.This object is achieved in that the length and brevity of the arcuate element by variation of the measured over the curvature of the arcuate element distance between the guide member and the discharge point is taken into account by the measured over the curvature of the arcuate element distance between the guide element and the delivery point is variably adjustable to take into account the length or shortness of the arcuate element.

Das Transportorgan umfaßt vorzugsweise einen Körper mit im wesentlichen kreisförmigem Umfang. Der Körper könnte beispielsweise aber auch S-förmig oder in anderer Weise speichenartig ausgebildet sein und fragmentarisch in Kreisbögen auslaufen. Die maulartige Aufnahme könnte im wesentlichen schlitzförmig oder spaltförmig ausgebildet sein, oder zum Beispiel aber auch fachartig. Bevorzugt sind mehrere derartiger Aufnahmen gleichmäßig verteilt vorgesehen, vorzugsweise zwei oder vier Aufnahmen.The transport member preferably comprises a body having a substantially circular circumference. For example, the body could also be S-shaped or spoke-like in some other way and could end up as fragments in circular arcs. The jaw-like receptacle could be substantially slit-shaped or slit-shaped, or, for example, but also like a professional. Preferably, several such recordings are provided evenly distributed, preferably two or four shots.

Das Zwischenführungselement umfaßt bevorzugt ein Rollelement, dem eine Rollführungsbahn zugeordnet ist. Dadurch wird bevorzugt dem bogenförmigen Element zwangsweise die notwendige Krümmung erteilt, ohne das Element in Querrichtung zu biegen oder zu wellen.The intermediate guide element preferably comprises a rolling element, which is associated with a rolling guide track. As a result, the arcuate element is preferably forcibly given the necessary curvature without bending or undulating the element in the transverse direction.

Die Rollführungsbahn kann eine Oberfläche des Körpers des Transportorganes selbst sein oder eines damit koaxial rotierbaren weiteren Körpers, der den Vorteil einer zusätzlichen Stützung und Auflage für das bogenförmige Element hat. Ist dieser zusätzliche Körper etwas größer als der Körper des Transportorgans, und ist vorzugsweise der Radius der Rollführungsbahn etwas kleiner als der radiale Abstand der radial äußeren Innenfläche der maulartigen Aufnahme, wird einerseits verhindert, daß die Vorderkante des bogenförmigen Elementes zu weit bis in den Aufnahmegrund vordringt und dort beschädigt wird und daß andererseits das bogenförmige Element durch die Zwischenführung zu sehr verwunden wird.The rolling guide track may be a surface of the body of the transport organ itself or a coaxially rotatable further body having the advantage of additional support and support for the arcuate element. If this additional body is slightly larger than the body of the transport member, and preferably the radius of the rolling guide track is slightly smaller than the radial distance of the radially outer inner surface of the jaw-like receptacle, on the one hand prevents the leading edge of the arcuate element is too far penetrates into the receiving base and is damaged there and that on the other hand, the arcuate element is wound too much by the intermediate guide.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß eine Abstandsvariation des Führungselementes mittels eines im wesentlichen lotrechten und einem damit gelenkig verbundenen, im wesentlichen waagerechten Hebelarm möglicht ist. Insbesondere kann eine Verstellung des Führungselementes auch während des Betriebes möglich sein. Vorzugsweise ist das Führungselement motorisch verstellbar. Auch eine radiale Nachgiebigkeit durch Abheben des Führungselementes kann mit Vorteil ermöglicht sein, um eventuelle Ungleichmäßigkeiten des effektiven Durchmessers des Transportorgans auszugleichen.A preferred embodiment of the invention provides that a distance variation of the guide element by means of a substantially vertical and hinged thereto, substantially horizontal lever arm is possible. In particular, an adjustment of the guide element may also be possible during operation. Preferably, the guide element is adjustable by motor. Also, a radial compliance by lifting the guide element can be advantageously made possible to compensate for any irregularities in the effective diameter of the transport member.

Ein Herausschieben des bogenförmigen Elementes aus der Aufnahme an der Abgabestelle ist dadurch einfach und automatisch möglich, daß dort ein gegenüber dem Transportorgan feststehender Anschlag für die in der Aufnahme eingesteckte Vorderkante des bogenförmigen Elementes angeordnet ist.A pushing out of the arcuate element from the receptacle at the delivery point is thereby easily and automatically possible that there is a fixed stop relative to the transport member for the inserted in the receptacle front edge of the arcuate element is arranged.

Eine andere Weiterbildung der erfindungsgemäßen Vorrichtung sieht vor, daß im Bereich der Abgabestelle ein Abdeckungsschutz eines Stapels aus abgelegten bogenförmigen Elementen gegenüber dem Transportorgan vorgesehen ist. Dies ermöglicht insbesondere, daß das Transportorgan kontinuierlich umlaufen kann, ohne den abgelegten Stapel zu beschädigen.Another development of the device according to the invention provides that in the area of the delivery point a cover protection of a stack of stored arc-shaped elements is provided relative to the transport member. This allows in particular that the transport member can rotate continuously without damaging the deposited stack.

Eine über die Querbreite besonders gut kontrollierte Handhabung des bogenförmigen Elementes ist dadurch möglich, daß bevorzugt mehrere koaxiale, zueinander beabstandete Transportorgane vorgesehen sind, vorzugsweise zwei Transportorgane spiegelbildlich bezüglich einer zur Rotationsachse senkrechten Spiegelebene angeordnet sind.A particularly well controlled over the transverse width handling of the arcuate element is possible in that preferably a plurality of coaxial, mutually spaced transport members are provided, preferably two transport members are arranged mirror images of a plane perpendicular to the axis of rotation mirror plane.

FIG. 3 shows a section through the device according to FIG. 1 along the dot-dash line in FIG. 1 in the direction of the arrows on the side view of the surroundings of a transport element.

Die Fig. 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Vorrichtung weitgehend von oben.Fig. 1 shows a perspective view of a device according to the invention largely from above.

Die erfindungsgemäße Vorrichtung umfaßt zwei als Umlenkscheiben 1 ausgebildete Transportorgane zum Transport von Bögen, nämlich zur Erfassung und Umlenkung der Bögen und zur Ablage der Bögen auf einen Stapel 6 aus Bögen auf einem Stapeltablett 7.The device according to the invention comprises two conveying members designed as deflecting disks 1 for transporting sheets, namely for detecting and deflecting the sheets and for depositing the sheets on a stack 6 of sheets on a stacking tray 7.

Das Funktionsprinzip der Vorrichtung kann am einfachsten zunächst einmal anhand der Fig. 3 erläutert werden, die eine der Umlenkscheiben 1 in der Seitenansicht mit ihrem Umfeld zeigt. Die Vorrichtung kann dazu als entlang der in Fig. 1 mit III bezeichneten, strichpunktierten Linie geschnitten angesehen werden.The principle of operation of the device can be explained most simply first of all with reference to FIG. 3, which shows one of the deflecting disks 1 in side view with its surroundings. The device can be regarded as cut along the dash-dotted line labeled III in FIG.

Zu transportierende Bögen werden der Umlenkscheibe 1, vorzugsweise aus dem Druckbereich einer Druckmaschine, mittels Papierpfadleitblechen 13 nacheinander zugeführt. Jeweils ein umzulenkender Bogen wird mit einem Transportrollenpaar 10 mit seiner Vorderkante tief in eine als Schlitz 20 ausgebildete maulartige Aufnahme der Umlenkscheibe 1 eingeschoben. Die äußere Wandung des Schlitzes 20 wird von einem Führungsblech 3 gebildet, das abgekantet an der Umlenkscheibe 1 befestigt ist. Der erfaßte Bogen wird mit seiner Vorderkante im Schlitz 20 ausreichend festgehalten, während die Umlenkscheibe 1 um ihre Welle angetrieben rotiert. Nach einer halben Drehung der Umlenkscheibe 1, also nach einer 180°-Wendung, gelangt der Bogen mit seiner Vorderkante an eine Stapelkante 5, schlägt dort an und kommt dadurch aus dem Schlitz 20 der weiter rotierenden Umlenkscheibe 1 frei und fällt auf den Stapel 6, wo er abgelegt bleibt. Die Umlenkscheibe 1 rotiert durch die entsprechend unterbrochene Stapelkante 5 hindurch. Um den zuoberst auf dem Stapel 6 abgelegten Bogen mit der rotierenden Umlenkscheibe 1 nicht zu beschädigen, ist der Arbeitsbereich der Umlenkscheibe 1 mit einem Schutz- oder Leitblech 4, das an der Stapelkante 5 befestigt ist, geschützt. Die Umlenkscheibe 1 rotiert vorzugsweise kontinuierlich und nicht getaktet, jedoch nicht notwendigerweise gleichmäßig. Sie kann beispielsweise bei der Übernahme und Abgabe eines Bogens langsamer laufen als bei dem eigentlichen Transport des Bogens. Da die Umlenkscheibe 1 zwei einander diametral gegenüberliegende Schlitze 20 aufweist und sie insoweit punktsymmetrisch zu ihrer Welle ausgebildet ist, kann gleichzeitig oben im Bereich der Transportrollen 10 eine Übernahme eines nächsten Bogens stattfinden, während eine Abgabe eines transportierten Bogens im Bereich der Stapelkante 5 erfolgt.Arcs to be transported are fed successively to the deflecting disk 1, preferably from the printing area of a printing machine, by means of paper path guide plates 13. In each case a deflected sheet is inserted with a pair of transport rollers 10 with its leading edge deep into a slot 20 formed as a jaw-like receptacle of the deflection plate 1. The outer wall of the slot 20 is formed by a guide plate 3, which is attached to the deflection plate 1 bent. The detected arc is sufficiently retained with its leading edge in the slot 20, while the deflection plate 1 about its shaft driven rotated. After half a turn of the deflection disk 1, ie after a 180 ° turn, the sheet reaches its front edge against a stacking edge 5, strikes there and thus comes out of the slot 20 of the further rotating deflection disk 1 and falls onto the stack 6, where he stays stored. The deflecting plate 1 rotates through the corresponding interrupted stacking edge 5 therethrough. In order not to damage the sheet deposited on top of the stack 6 with the rotating deflecting disk 1, the working area of the deflecting disk 1 is protected by a protective or guide plate 4 which is fastened to the stacking edge 5. The deflection plate 1 preferably rotates continuously and not clocked, but not necessarily evenly. It can, for example, run slower during the takeover and delivery of a sheet than during the actual transport of the sheet. Since the deflecting plate 1 has two diametrically opposite slots 20 and it is so far point-symmetrical to its shaft formed at the same time take place in the area of the transport rollers 10 takeover of a next sheet, while a delivery of a transported sheet in the stack edge 5 takes place.

Um auch kürzere und / oder schwerere Bögen, insbesondere Papierbögen, sicher und kontrolliert transportieren zu können, umfaßt die Vorrichtung neben der Umlenkscheibe 1 eine koaxial zu dieser angeordnete und mit dieser rotierende Führungsscheibe 2, auf der eine Andruckrolle 11, die im wesentlichen an einem statischen Gerüst der Vorrichtung oder dergleichen angeordnet ist, abrollt und die als Zwischenführungselement zwischen den Transportrollen 10 und der Stapelkante 5 den im Schlitz 20 erfaßten Bogen führt und auf die Krümmung der Umlenkscheibe 1 bzw. der Führungsscheibe 2 zwingt. Prinzipiell könnte eine solche Andruckrolle 11 auf der Umlenkscheibe 1 selbst abrollen, jedoch wird durch die zusätzliche Führungsrolle 2 weiterer Raum für die in ihrer Zwischenstellung veränderbare Andruckrolle 11 gewonnen. Auch ergibt diese Führungsscheibe 2 eine zusätzliche Anlage für den Bogen. Die Umlenkscheibe 1, wie auch die Führungsscheibe 2 müssen dabei gar nicht einmal als vollständige Scheiben ausgebildet sein. Wie aus der Fig. 3 zu ersehen ist, hat die Führungsscheibe 2 auch einen etwas größeren Radius als die Innenseite des Schlitzes 20, aber einen etwas kleineren Radius als dessen vom Führungsblech 3 gebildete Außenseite.In order to be able to transport shorter and / or heavier sheets, in particular paper sheets, safely and in a controlled manner, the apparatus comprises, in addition to the deflecting disk 1, a guide disk 2 arranged coaxially therewith and rotating thereon, on which a pinch roller 11 which is essentially attached to a static Scaffold of the device or the like is arranged, unrolls and the intermediate guide element between the transport rollers 10 and the stack edge 5, the arc 20 detected in the slot and leads to the curvature of the deflection plate 1 and the guide plate 2 forces. In principle, such a pressure roller 11 could roll on the deflection plate 1 itself, but is gained by the additional guide roller 2 further space for the changeable in its intermediate position pinch roller 11. Also, this guide disc 2 provides an additional attachment for the bow. The deflection plate 1, as well as the guide plate 2 need not even be designed as complete discs. As can be seen from Fig. 3, the guide plate 2 also has a slightly larger radius than the inside of the slot 20, but a slightly smaller radius than its outer side formed by the guide plate 3.

Dadurch wird ein Ein- und Ausfädeln des Bogens im Schlitz 20 nicht behindert, jedoch ein zu tiefes Eindringen im Schlitz vermieden und ein sicherer Halt erzeugt.As a result, a threading and unthreading of the sheet in the slot 20 is not hindered, but avoids too deep penetration in the slot and creates a secure hold.

Zur Erläuterung der Verstellbarkeit der Andruckrolle 11, besser gesagt der Andruckrollen 11, und der übrigen Funktionen der Vorrichtung wird nochmals auf die Fig. 1 Bezug genommen.To explain the adjustability of the pinch roller 11, that is to say the pinch rollers 11, and the remaining functions of the device, reference is again made to FIG.

Zunächst einmal ist aus der Figur 1 ersichtlich, daß Umlenkscheiben 1 und Führungsscheiben 2, Andruckrollen 11 und auch weitere Elemente der Vorrichtung doppelt vorhanden sind, indem die Vorrichtung im wesentlichen spiegelsymmetrisch ausgebildet ist.First of all, it can be seen from FIG. 1 that deflecting disks 1 and guide disks 2, pressure rollers 11 and also further elements of the device are present in duplicate, in that the device is embodied essentially mirror-symmetrically.

Aus der Fig. 1 ist zudem die Anordnung des Leitbleches 4 zum Schutz des Stapels 6 erkennbar.From Fig. 1, the arrangement of the guide plate 4 for the protection of the stack 6 can also be seen.

Die gelenkige, verstellbare Anordnung der Andruckrollen 11 ist ebenfalls in Fig. 1 gut erkennbar. Die Position der Andruckrollen 11 ist auf dem Umfang der Führungsscheiben 2 veränderbar. Je nach Format des zu handhabenden bogenförmigen Elementes wird das Andruckrollenpaar 11 mehr oder weniger weit in Richtung auf die Stapelkante 5 abgesenkt, und zwar bevorzugt so weit, daß der Abstand entlang des Krümmungsbogens zwischen den Andruckrollen 11 und der Stapelkante 5 geringfügig kleiner ist als die Länge des bogenförmigen Elementes. Beim Anstoßen der Vorderkante des bogenförmigen Elementes an der Stapelkante wird dann dessen Ende mit den koaxial rotierenden Führungsscheiben 2 und Umlenkscheiben 1 aus dem Andruckbereich der Andruckrollen 11 herausgefördert und kommt dadurch zur Ablage auf dem Stapel 6 frei. Das bogenförmige Element wird also sicher an die Stapelkante 5 herangeführt und nicht zu stark verwunden bis das bogenförmige Element ganz aus dem Andruckrollenangriff heraustritt.The articulated, adjustable arrangement of the pressure rollers 11 is also clearly visible in Fig. 1. The position of the pressure rollers 11 is variable on the circumference of the guide plates 2. Depending on the format of the sheet-shaped element to be handled, the pinch roller pair 11 is lowered more or less in the direction of the stack edge 5, preferably so far that the distance along the arc of curvature between the pinch rollers 11 and the stack edge 5 is slightly smaller than the length of the arcuate element. When abutting the leading edge of the arcuate element at the stack edge then the end of which is conveyed out with the coaxial rotating guide discs 2 and deflecting discs 1 from the Andruckbereich the pinch rollers 11 and thus comes to rest on the stack 6 free. The arcuate element is thus brought safely to the stack edge 5 and not too strong wound until the arcuate element emerges completely from the Andruckrollenangriff.

Das Andruckrollenpaar 11 ist dreh-schwenkbar angeordnet. Hierdurch sind die Andruckrollen auch während des Förderbetriebes von den Führungsscheiben 2 abhebbar. Hierfür sind waagerechte Hebelarme 9 vorgesehen, die an einer Achse für die Andruckrollen 11 angreifen und von einem Antrieb 15 über einen Zahnriementrieb 14 angetrieben werden. Zur Verstellung der Andruckrollen 11 entlang des Umfanges der Führungsscheiben sind zudem senkrechte Hebelarme 8 vorgesehen, die mit den waagerechten Hebelarmen 9 gelenkig verbunden sind und mittels eines Antriebes 12 angetrieben werden. Der Antrieb 15 ist mit Vorteil auf dem senkrechten Hebelarm 9 gelagert, wodurch sichergestellt ist, daß bei der Verstellbewegung mit dem Antrieb 12 keine Abhebbewegung der Andruckrollen 11 eingeleitet wird. Eine Abhebbewegung der Andruckrollen 11 ist erforderlich, damit wechselnde effektive Außendurchmesser der Umlenkscheiben 1, die durch den Verlauf und die Ausbildung des Schlitzes 20 auftreten können, das bogenförmige Element nicht beanspruchen. Die Schwenkachsen der senkrechten Hebelarme 8 sind koaxial zu der Welle für die Umlenkscheiben 1 und Führungsscheiben 2.The pinch roller pair 11 is arranged rotatably pivotable. As a result, the pressure rollers are also during the conveying operation of the guide plates. 2 lifted. For this purpose, horizontal lever arms 9 are provided, which act on an axis for the pressure rollers 11 and are driven by a drive 15 via a toothed belt drive 14. For adjusting the pressure rollers 11 along the circumference of the guide discs also vertical lever arms 8 are provided, which are hingedly connected to the horizontal lever arms 9 and driven by a drive 12. The drive 15 is advantageously mounted on the vertical lever arm 9, which ensures that during the adjustment movement with the drive 12 no lifting movement of the pinch rollers 11 is initiated. A lifting movement of the pressure rollers 11 is required so that changing effective outer diameter of the deflection plates 1, which may occur through the course and the formation of the slot 20, the arcuate element does not claim. The pivot axes of the vertical lever arms 8 are coaxial with the shaft for the deflecting disks 1 and guide disks 2.

Da durch den Stapelprozeß selbst bedingt, bei einem Formatwechsel der bogenförmigen Elemente nur von einem größeren auf ein kleineres Format übergegangen wird, werden in diesem Verlauf die Andruckrollen 11 allenfalls immer weiter in Richtung auf die Stapelkante 5 abgesenkt. Die Möglichkeit einer gegenläufigen Bewegung muß daher nicht unbedingt vorgesehen werden.Since conditioned by the stacking process itself, with a format change of the arcuate elements is only transferred from a larger to a smaller format, in this process, the pinch rollers 11 are at most always lowered further in the direction of the stack edge 5. The possibility of an opposing movement does not necessarily have to be provided for.
