Description

Die Erfindung betrifft ein Verfahren zum Abteilen von Teilstapeln von einem Gesamtstapel und zum Ablegen jedes Teilstapels in schuppenförmiger Lage, d.h. also in geschuppter Formation; außerdem betrifft die Erfindung Vorrichtungen zur Durchführung dieses Verfahrens.The invention relates to a method for dividing partial stacks from an entire stack and for depositing each partial stack in a flaky position, i.e. thus in a shingled formation; the invention also relates to devices for carrying out this method.

Maschinell und auch vollautomatisch arbeitende Verfahren bzw. Vorrichtungen zum Abteilen von Teilstapeln von einem Gesamtstapel, wie dies bei der Beschickung von die Bogen des Gesamtstapels weiterverarbeitenden Maschinen oder Vorrichtungen erforderlich ist, sind bisher nicht dazu in der Lage, die Teilstapel in geschuppte Formation, vorher voneinander getrennt und zwischenbeltiftet, abzulegen, wobei das Material der einzelnen Böqen beispielsweise Papier, Kunststoff, Metallfolie oder dergleichen sein kann. Die bekannten Verfahren und Vorrichtungen können die Teilstapel vielmehr ausschließlich in genau derselben Form, wie sich diese auf dem Gesamtstapel befinden, ablegen. Manche weiterverarbeitenden Maschinen (als Beispiele seien lediglich Rütteltische, aber auch andere weiterverarbeitende Anlagen oder Transportvorrichtungen andere weiterverarbeitende Anlagen oder Transportvorrichtungen genannt). Viele dieser Anlagen, und zwar gerade Rütteltische, benötiqen aber eine schuppenförmige Linlegung der vom Gesamt- stapel abgenommenen Teilstapel, und benötigen auch eine Relativ- ; verschiebunq zu-einander, mit Belüftung, um ein Ankleben einzelnerProcesses and devices for dividing partial stacks from an entire stack, which are automatic and also fully automatic, as is required when loading machines or devices that process the sheets of the entire stack, have so far not been able to separate the partial stacks from one another in shingled formation separated and interim donated, the material of the individual sheets can be, for example, paper, plastic, metal foil or the like. Rather, the known methods and devices can only store the partial stacks in exactly the same form as they are on the entire stack. Some further processing machines (examples include only vibrating tables, but also other further processing plants or transport devices other processing plants or transport devices). However, many of these systems, especially vibrating tables, require a scaled arrangement of the partial stacks removed from the entire stack, and also require a relative; shifting to each other, with ventilation to stick individual

Bögen aneinander bei der Weiterverarbeitung zu vermeiden, was unweigerlich zu Ausschuß führt. Ein Aneinanderkleben der aufeinanderfolgenden Bögen kann beispielsweise durch elektrostatische Aufladung, durch hohe Luftfeuchtigkeit, und noch durch eine Reihe von anderen äußeren Einflüssen hervorgerufen werden.Avoiding sheets against each other during finishing, which inevitably leads to rejects. Adhesion of the successive sheets can be brought about, for example, by electrostatic charging, high air humidity, and a number of other external influences.

Aus diesem Grunde war das Abteilen von Teilstapeln von einem Gesamtstapel und das Ablegen jedes Teilstapels in schuppenförmiger Lage (wodurch ja zwangsläufig eine Relativverschiebung zwischen den einzelnen Bögen und damit eine gewisse Trennung derselben voneinander hervorgerufen wird) nur von Hand möglich, und das ist nicht nur eine zeitraubende, sondern insbesondere bei größeren Bogenformaten auch eine überaus anstrengende Tätigkeit. Die weiterverarbeitende Vorrichtung könnte unter Umständen, in Hinblick auf ihre gegebene Kapazität, wesentlich mehr Boqen pro Zeiteinheit verarbeiten, als dies wegen des genannten manuellen Zwischenschritts möglich ist.For this reason, the division of partial stacks from an entire stack and the placement of each partial stack in a scale-like position (which inevitably causes a relative shift between the individual sheets and thus a certain separation of them from one another) was only possible by hand, and this is not only one time-consuming, but also a very exhausting task, especially for larger sheet formats. The further processing device could possibly, in view of its given capacity, process significantly more boqs per unit of time than is possible because of the manual intermediate step mentioned.

Aufgabe der Erfindung ist daher die Schaffung eines Verfahrens und einer zur Durchführung dieses Verfahrens geeiqneten Vorrichtung, mittels derer es möglich ist, Teilstapel von einem Gesamtstapel abzuteilen und sodann in schuppenförmiger Laqe abzulegen, und zwar soll dieses Verfahren und diese Vorrichtung sowohl bei größeren Formaten als aber auch insbesondere bei dünneren Papieren, bei denen die diesbezüglichen Schwierigkeiten am größtten sind, wirksam und störungsfrei eingesetzt werden können.The object of the invention is therefore to provide a method and a device suitable for carrying out this method, by means of which it is possible to divide partial stacks from an entire stack and then to store them in a flaky form, namely this method and this device both in larger formats but can also be used effectively and without problems, particularly in the case of thinner papers where the difficulties in this regard are greatest.

Diese Aufgabe wird nach der Erfindung durch das im Patentanspruch 1 qeschilderte Verfahren gelöst, und bauliche Merkale von Vorrichtungen zur Durchführung dieses Verfahrens finden sich in den Ansprüchen 2 bis 5.This object is achieved according to the invention by the method described in claim 1, and structural features of devices for carrying out this method can be found in claims 2 to 5.

Die einzelnen Schritte des Verfahrens nach der Erfinduna sowie die Merkmale der Vorrichtung zur Durchführung dieses Verfahrens, und die Wirkungen dieses Verfahrens werden dm zweckmäßigsten anhand der Zeichnung beschrieben, in der ein Ausführungsbeispiel einer Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens sowiet wie nur irgend möglich schematisiert darqestellt ist, und zwar zeiqen die Fig. 1 bis 7 verschiedene Zustände der Vorrichtung (und damit verschiedene Verfahrensschritte) in Seitenansicht; Fig. 8 zeigt eine Stirnansicht der wichtigsten Teile der Vorrichtung zwecks Erläuterung der Verschwenkbarkeit der Vorrichtung bei Anwendung auf schrägliegende Weiterverarbeitungsebenen in der weiterverarbeitenden Maschine oder Vorrichtung.The individual steps of the method according to the invention as well as the features of the device for carrying out this method and the effects of this method are the most expedient described with reference to the drawing, in which an embodiment of a device for performing the method according to the invention is shown as schematically as possible, namely that FIGS. 1 to 7 show different states of the device (and thus different method steps) in a side view; FIG. 8 shows an end view of the most important parts of the device in order to explain the pivotability of the device when used on inclined further processing levels in the further processing machine or device.

Gleiche Teile sind in allen Fig. mit denselben Bezugsziffern bezeichnet.The same parts are designated with the same reference numerals in all the figures.

Von dem Gesamtstapel 1 wird ein Teilstapel 2, dessen ursprüngliche Lage am rechten oberen Ende des Gesamtstapels 1 strichpunktiert eingezeichnet ist, durch schräg nach oben/hinten (Pfeil 3) gerichtetes Anfahren einer mit Noppen oder dergleichen versehenen, angetriebenen Aufrichtwalze 4, deren Ausgangslage rechts vom Gesamtstapel ebenfalls strichpunktiert dargestellt is und deren Antriebsrichtung mit einem Pfeil bezeichnet ist, gegen den oberen Teil der Gesamtstapel-Seitenfläche 5 um eine zu diese Zeitpunkt festgehaltene Umlenkwalze 6, die auf der Gesamtstapel-Qberfläche aufliegt, schräg nach oben/hinten bis an eine Teilstapel-Anlagefläche 7 umgebogen. Fig. 1 zeigt diesen Zustand der Anlage des Teilstapels an der Teilstapel-Anlage 7. Dabei gelangt die ursprünglich gerade Vorderkante des Teilstapels 2, wie bei 8 dargestellt, in eine geschuppte Formation. Dieser Zustand ist in Fig. 1 der Zeichnunq dargestellt.From the entire stack 1, a partial stack 2, the original position of which is shown in dash-dotted lines at the upper right end of the entire stack 1, is moved obliquely upwards / backwards (arrow 3) to a driven erecting roller 4 provided with knobs or the like, the starting position of which is to the right of The entire stack is also shown in dash-dot lines and the drive direction of which is indicated by an arrow, against the upper part of the entire stack side surface 5 by a deflection roller 6 which is held at this time and which rests on the entire stack surface, obliquely upwards / backwards to a partial stack. Contact surface 7 bent. 1 shows this state of the system of the partial stack on the partial stack system 7. The originally straight front edge of the partial stack 2, as shown at 8, reaches a scaled formation. This state is shown in Fig. 1 of the drawing.

Anschließend wird nun der vordere Bereich des umgebogenen Teils des Teilstapels 2 von mehreren herunterschwenkenden Greifern 9 erfaßt, deren Schwenkachse mit lo bezeichnet ist. Dieser Zustand ist in Fig. 2 dargestellt; die vorherige Ausqangslage der Greifer 9 ist weiter oben in strichpunktierten Linien dargestellt. Nach dieser Erfassung des vorderen Bereichs des Teilstapels 2 durch die Greifer 9 kann der Antrieb der Aufrichtwalze 4 abgeschaltet und diese in ihrer rechts unten strichpunktierte Ausgangslage zurückbewegt werden. Durch diese Maßnahme wird gewährleistet, daß auch Teilstapel aus dünnen und labilen Papieren, oder ähnlichen Materialien (Kunststoff-Folien oder dergleichen) nicht durch ihr Eigengewicht in sich zusammensinken können, sondern daß vielmehr die hervorgerufene und erwünschte Schuppenbildung erhalten bleibt. Jetzt wird die Umlenkwalze 6 freigegeben, sodaß sie frei auf der Stapeloberseite 11 abrollen kann, und die Greifer 9 werden auf einer Kreisbahn nach oben und gleichzeitig horizontal über die Stapel-Oberseite 11 hinweg nach links bewegt (das ist der Zustand etwa nach Fig. 3), wobei sich der Teilstapel 2 an eine im Bereich der Teilstapel-Anlage zur Greifer-Schwenkachse lo konzentrische, gebogene Führung 12 anlegt und infolge dessen die Form eines S annimmt. Das ergibt infolge der geometrischen Verhältnisse (die untere Bahn jedes Teilstapels hat einen wesentlich längeren Weg alsdie obere Bahn desselben Teilstapels) nicht nur die schon vorhergehend erzielte Schuppung, sondern auch die an der Stelle 13 dargestellte Trennung der einzelnen Bögen voneinander, und deren Belüftung. Dieser Zustand ist in Fig. 3 der Zeichnung dargestellt. Dieser Vorgang der Verdrehung der Greifer 9 in Uhrzeigerrichtung rechts nach oben um ihre Mittellinie und der Verfahrung dieser Mittellinie nach links, immer mit den durch Pfeile dargestellten Bewegungsrichtungen der einzelnen Teile, führt dann zu der Lage nach Fig. 4, aus der außerdem ersichtlich ist, daß während dieser ganzen Vorgänge das andere Ende des Gesamtstapels 1 durch eine Stapel klemme 14 festgehalten wird. Nur dadurch kann sich ja die gewünschte Auf- fächerung der einzelnen Bogen ergeben. Wenn nun am Ende der Abhebebewegung des Teilstapels 2 vom Gesamtstapel 1 die Umlenkwalze 6 auf diese Stapelklemme 14 auftrifft, dann wird diese ge-; löst, d.h. also geöffnet, sodaß der Teilstapel 2 gänzlich vom Gesamtstapel 1 abqehoben werden kann. Anschließend an diese Lösung der Klemmung werden die Greifer 9 mit dem geschuppten und geklemmten Teilstapel 2 weiter bis in die obere Endlage bewegt, und wenn diese Bewegung aboeschlossen ist, liegen die Bogen des abqehobenen Teilstapels 2 schuppenförmig geklemmt, voneinander ge- trennt und belüftet auf der kreisbogenförmigen Führung 12 auf.Subsequently, the front area of the bent-over part of the partial stack 2 is gripped by several swiveling grippers 9, the swiveling axis of which is denoted by lo. This state is shown in Fig. 2; the previous initial position of the grippers 9 is shown further above in dash-dotted lines. After this detection of the front area of the partial stack 2 by the grippers 9 can switch off the drive of the erecting roller 4 and move them back to their starting position in dash-dotted lines at the bottom right. This measure ensures that even partial stacks of thin and unstable papers, or similar materials (plastic films or the like) cannot collapse by their own weight, but rather that the evoked and desired scale formation is retained. Now the deflecting roller 6 is released so that it can roll freely on the top of the stack 11, and the grippers 9 are moved upwards in a circular path and at the same time horizontally to the left over the top of the stack 11 (this is the state approximately according to FIG. 3 ), the sub-stack 2 bears against a curved guide 12 which is concentric in the region of the sub-stack system with the gripper pivot axis lo and consequently assumes the shape of an S. As a result of the geometrical relationships (the lower path of each partial stack has a much longer path than the upper path of the same partial stack), this results not only in the shingling previously achieved, but also in the separation of the individual arches from one another shown at point 13, and their ventilation. This state is shown in Fig. 3 of the drawing. This process of turning the grippers 9 clockwise upward around their center line and moving this center line to the left, always with the directions of movement of the individual parts represented by arrows, then leads to the position according to FIG. 4, from which it can also be seen that that during these whole operations, the other end of the entire stack 1 is clamped by a stack 14. This is the only way to achieve the desired fanning out of the individual sheets. If the deflecting roller 6 strikes this stack clamp 14 at the end of the lifting movement of the partial stack 2 from the entire stack 1, then this is clamped; triggers, that is, opened, so that the partial stack 2 can be completely lifted off the entire stack 1. Subsequent to this solution of the clamping, the grippers 9 with the flaked and clamped partial stack 2 are moved further into the upper end position, and when this movement is completed, the sheets of the partial stack 2 lifted off are clamped in a scale-like manner, separated from one another and ventilated on the circular-arc-shaped guide 12.

Nun werden die Greifer 9, und damit die gesamte Vorrichtung, so weit zurückbewegt, bis sie sich über der Weiterverarbeitungsebene 15 der weiterverarbeitenden Vorrichtung oder Maschine befinden, die waagerecht sein kann, aber auch, wie in Fig. 5 dargestellt, geneigt sein kann. Die für solche schräggeneigte Ablage vorgesehenen, erfindungsaemäßen Mittel an der Vorrichtung sind in Fig. 8 dargestellt und werden weiter unten anhand dieser Figur beschrieben.Now the grippers 9, and thus the entire device, are moved back until they are above the further processing level 15 of the further processing device or machine, which can be horizontal, but can also be inclined, as shown in FIG. 5. The means according to the invention for such inclined storage on the device are shown in FIG. 8 and are described below with reference to this figure.

Sobald die Vorrichtung die richtige Lage oberhalb der Weiterverarbeitungsanlage 15 erreicht hat, werden die Greifer 9 wieder heruntergeschwenkt, und bei Ankommen des freien Endes des Teilstapels 2 auf der Weiterverarbeitungsebene 15, was durch eine Sensorkontrolle 16 festgestellt wird, werden die Greifer 9 auch von dem freien Ende hinweg horizontal zurückbewegt. Den Zustand, wenn das freie untere Ende des Teilstapels 2 die Weiterbearbeitungsfläche 15 erreicht, ist in Fig. 5 dargestellt, und dieser Zustand wird durch eine Sensorkontrolle 16 ermittelt. Nun werden die Greifer 9 horizontal zurückbewegt und gleichzeitig zurUckverschwenkt; dieser Zustand ist in Fig. 6 qezeigt. Kurz vor Erreichen des Endes der Weiterverarbeitungsebene 2 werden die Greifer 9 geöffnet, sodaß nunmehr der Teilstapel 2, voll schuppenartig, auf die Weiterverarbeitungsebene 15 herabfallen kann. Anschließend werden die Greifer 9 wieder in ihre Ausganqslage zum Erfassen des nächsten Teilstapels 2 zurückbewegt. Damit das Zusammenwirken der Aufrichtwalze 4 mit dem Gesamtstapel 1 immer in der gleichen Weise funktioniert, ist es natürlich erforderlich, den Gesamtstapel 1 vor dem nächsten Einsatz der Aufrichtwalze 4 um die Dicke des vorher abgenommenen Teilstapels anzu- heben. Das kann aber auch bereits ab dem Zeitpunkt erfolgen, ab dem die Greifer 9 von dem Gesamtstapel weg über die Weiterverarbeitungsebene 15 bewegt worden sind.As soon as the device has reached the correct position above the further processing system 15, the grippers 9 are pivoted down again, and when the free end of the partial stack 2 arrives at the further processing level 15, which is determined by a sensor control 16, the grippers 9 are also removed from the free one Moved back horizontally at the end. The state when the free lower end of the partial stack 2 reaches the further processing surface 15 is shown in FIG. 5, and this state is determined by a sensor control 16. Now the grippers 9 are moved back horizontally and pivoted back at the same time; this state is shown in FIG. 6. Shortly before reaching the end of the further processing level 2, the grippers 9 are opened, so that the partial stack 2 can now fall down onto the further processing level 15 in a completely scale-like manner. The grippers 9 are then moved back into their starting position for gripping the next partial stack 2. So that the interaction of the erecting roller 4 with the total stack 1 always works in the same way, it is of course necessary to lift the entire stack 1 before the next use of the erecting roller 4 by the thickness of the previously removed partial stack. However, this can also take place from the point in time at which the grippers 9 away from the entire stack via the forwarders working level 15 have been moved.

Am Ende des Vorgangs befinden sich jedenfalls die einzelnen Bögen des Teilstapels 2 in schuppenförmiger Formation auf der Weiterverarbeitungsebene, wie die am rechten Ende der Letzteren dargestellte Endlage in Fig. 4 erkennen läßt.At the end of the process, the individual sheets of the partial stack 2 are in a scale-like formation on the further processing level, as can be seen from the end position shown at the right end of the latter in FIG. 4.

Das Anheben des Gesamtstapels in die gewünschte Höhenlage kann durch eine Lichtschranke oder ein anderes Schaltelement festgestellt werden, wodurch dann die Hebevorrichtung für den Gesamtstapel abgeschaltet wird. Dabei können unterschiedliche Dicken der abzuhebenden Teilstapel unschwer eingestellt werden.The lifting of the entire stack into the desired height can be determined by a light barrier or another switching element, which then turns off the lifting device for the entire stack. Different thicknesses of the partial stacks to be lifted can easily be set.

Die gebogene Führung 12, die zeitweise auch als Auflage für den Teilstapel dient, wird zweckmäßiq aus mehreren, einzelnen, zueinander parallelen Stangen, Rohren, Flacheisen oder dergleichen qebildet.The curved guide 12, which at times also serves as a support for the partial stack, is expediently formed from a plurality of individual rods, tubes, flat bars or the like which are parallel to one another.

Um auch auf in Querrichtung schrägstehenden Weiterverarbeitunqsebenen die Teilstapel ablegen zu können, wird in zweckmäßiger weiterer Ausbildung der Erfindung die gesamte Vorrichtung von einem balkenartigen Kopf 17 getraqen, sh. Fig. 8, und dieser Kopf ist um eine Schwenkachse 18 verschwenkbar, die in Quermitte dieses balkenförmiqen Kopfes 17, in Stapel-Längsrichtung horizontal verläuft. Um diese Schwenkachse 18 ist der Kopf 17 und damit die gesamte Vorrichtung schwenkbar und in jeder beliebigen Einstellung, nämlich parallel zur jeweiligen Weiterverarbeitungsebene 15, feststellbar.In order to be able to store the partial stacks even on further processing levels that are inclined in the transverse direction, the entire device is struck by a beam-like head 17 in a practical further embodiment of the invention, see FIG. Fig. 8, and this head is pivotable about a pivot axis 18 which runs horizontally in the longitudinal direction of the stack in the transverse center of this beam-shaped head 17. The head 17 and thus the entire device can be pivoted about this pivot axis 18 and can be locked in any setting, namely parallel to the respective further processing level 15 .

Die Umlenkwalze 6 kann, was in der Zeichnung nicht dargestellt ist, einzelne vorstehende Noppenstreifen an ihrem Umfang auf- weisen, die von ihrer Längsmitte aus spiralförmig, und zwar in den beiden Hälften gegenläufig zueinander, im Sinne eines Auseinanderziehens des Bogens in seiner Breite, d.h. also glättend, wirken.The deflecting roller 6, which is not shown in the drawing, can have individual protruding nub strips on its circumference, which spiral from its longitudinal center, in opposite directions to one another in the two halves, in the sense of a pulling apart of the sheet in its width, i.e. so smooth, work.
