Description

Die Erfindung betrifft eine Fördereinheit für flache Gegenstände gemäß dem Oberbegriff des Anspruches 1.The invention relates to a conveyor unit for flat objects according to the preamble of claim 1.

Derartige Fördereinheiten werden z. B. in Falzapparaten eingesetzt, um Signaturen zu fördern, die zuvor von einer Bahn eines Bedruckstoffs abgeschnitten worden sind.Such conveyor units are z. B. used in folders to promote signatures that have been previously cut off from a web of a substrate.

Die Signaturen bestehen aus einer variablen Zahl von Bogen, die untereinander unverbunden sind. Es ist daher von großer Bedeutung bei der Förderung der Signaturen, dass die zwei endlosen Bänder und der Zylinder sich mit exakt aufeinander abgestimmten Geschwindigkeiten bewegen, um zu vermeiden, dass auf zwischen ihnen eingeklemmte Signaturen Scherkräfte einwirken, die zu einer Verformung und zu einem Auffächern der Signaturen im Laufe des Transports führen können.The signatures consist of a variable number of sheets, which are unconnected to each other. It is therefore of great importance in promoting the signatures that the two endless belts and the cylinder move at exactly matched speeds to avoid that shingles clamped between them act on shearing forces resulting in deformation and fanning of the signatures Signatures during transport.

Bei herkömmlichen Fördereinheiten der oben angegebenen Art wird das die Mantelfläche des Zylinders teilweise umschlingende erste endlose Band über den Zylinder durch Reibung angetrieben. Infolgedessen entspricht die Bahngeschwindigkeit des ersten Bandes der Umfangsgeschwindigkeit des Zylinders, wenn zwischen beiden keine Gegenstände gefördert werden. Wenn sich geförderte Gegenstände im Umschlingungsbereich zwischen dem Zylinder und dem ersten Band befinden, so wirkt sich dies für die Geschwindigkeit des ersten Bandes wie eine Vergrößerung des Durchmessers des Zylinders aus. Die Geschwindigkeit des ersten Bandes nimmt also mit der Dicke der zu fördernden Gegenstände zu. Die Bewegung des zweiten endlosen Bandes ist über ein Übersetzungsgetriebe mit einem fest vorgegebenen Übersetzungsverhältnis an die Drehung des Zylinders gekoppelt. Die Geschwindigkeit des zweiten Bandes ist deshalb konstant. Dadurch ist vorgegeben, dass die zwei Bänder nur bei einer bestimmten Dicke der zu fördernden Gegenstände exakt gleich laufen, so dass die Gegenstände keinen Scherungskräften ausgesetzt sind.In conventional conveyor units of the type indicated above, the first endless belt, which partially envelops the lateral surface of the cylinder, is driven over the cylinder by friction. As a result, the web speed of the first belt corresponds to the peripheral speed of the cylinder when no articles are conveyed between them. If conveyed objects are in the wrap area between the cylinder and the first belt, this will affect the speed of the first belt like an increase in the diameter of the cylinder. The speed of the first band thus increases with the thickness of the objects to be conveyed. The movement of the second endless belt is coupled via a transmission gear with a fixed predetermined transmission ratio to the rotation of the cylinder. The speed of the second band is therefore constant. This dictates that the two bands only at a certain thickness of the objects to be conveyed run exactly the same, so that the objects are not exposed to shear forces.

Die DE 94 17 127 U1 und die EP 0 205 143 A2 beschreiben jeweils einen Sammelzylinder, an dessen Umfang ein Bandsystem anliegt und dem über zwei weitere zusammenwirkende Bandsysteme Bogen zugeführt werden.DE 94 17 127 U1 and EP 0 205 143 A2 each describe a collecting cylinder, on the circumference of which a band system bears and to which two more cooperating band systems feed sheets.

Die US 5 405 126 A beschreibt einen Falzapparat mit von einem Elektromotor angetriebenen Bändern.US 5,405,126 A describes a folder with belts driven by an electric motor.

Die US 3 363 520 A offenbart einen Sammelzylinder für Bogen mit mehreren Bändern, wobei ein Band vom Sammelzylinder angetrieben ist.US 3,363,520 A discloses a collection cylinder for multiple-band sheets with a belt driven by the collection cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine Fördereinheit für flache Gegenstände zu schaffen.The invention has for its object to provide a conveyor unit for flat objects.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass auch bei unterschiedlicher Dicke der zu fördernden Gegenstände stets Gleichlauf zwischen beiden Seiten der Förderstrecke auf deren gesamter Länge hergestellt werden kann, so dass die Gegenstände schonend und scherungsfrei gefördert werden können.The achievable with the present invention consist in particular that even with different thickness of the objects to be conveyed always synchronization between both sides of the conveyor line can be made on the entire length, so that the items can be promoted gently and shear-free.

Zu diesem Zweck ist vorgesehen, dass die Förderstrecke der Fördereinheit in zwei aufeinanderfolgende Abschnitte unterteilt ist, wobei in einem Abschnitt ein Teil des Umfangs des Zylinders und das erste Förderband gegenüberliegen und in einem zweiten Teil ein zweites und ein drittes Förderband.For this purpose, it is provided that the conveying path of the conveyor unit is subdivided into two successive sections, wherein in one section a part of the circumference of the cylinder and the first conveyor belt are opposed and in a second part a second and a third conveyor belt.

Durch Kopplung, insbesondere mechanische Kopplung der Bewegung des zweiten und dritten Endlosbandes sind Geschwindigkeitsabweichungen zwischen beiden exakt auf Null reduzierbar, so dass unabhängig von der Länge des von diesen Endlosbändern begrenzten Abschnitts der Förderstrecke keine Scherung der geförderten Produkte auftreten kann.By coupling, in particular mechanical coupling of the movement of the second and third endless belt, speed deviations between the two can be reduced to exactly zero, so that regardless of the length of the section of the conveying section delimited by these endless belts, there is no shear of the conveyed products can occur.

Gemäß einer einfachen Ausgestaltung sind das zweite und das dritte Endlosband über ein Übersetzungsgetriebe an die Drehbewegung des Zylinders gekoppelt, wobei das Übersetzungsverhältnis des Übersetzungsgetriebes so festgelegt ist, dass die Geschwindigkeiten der beiden Endlosbänder exakt mit der Umfangsgeschwindigkeit des Zylinders übereinstimmen.According to a simple embodiment, the second and the third endless belt are coupled via a transmission gear to the rotational movement of the cylinder, wherein the transmission ratio of the transmission gear is set so that the speeds of the two endless belts exactly match the peripheral speed of the cylinder.

Gemäß einer aufwendigeren Ausgestaltung ist eine Antriebseinrichtung für das zweite und das dritte Endlosband unabhängig von der Drehgeschwindigkeit des Zylinders regelbar. Mit ihr kann eine an die jeweilige Dicke des geförderten Produkts und die daraus resultierende Geschwindigkeit des ersten Endlosbandes angepasste Geschwindigkeit des zweiten und dritten Bandes eingeregelt werden, wobei hier geringfügige Abweichungen zwischen einer unter dem Gesichtspunkt des verformungsfreien Förderns der Produkte optimalen Geschwindigkeit des zweiten und dritten Bandes und ihrer tatsächlichen Geschwindigkeit viel eher toleriert werden können als bei der oben erläuterten Fördereinheit mit zwei Endlosbändern. Bei der erfindungsgemäßen Fördereinheit führt eine solche Abweichung nämlich lediglich zu einer geringfügigen Zugbeanspruchung oder einer vorübergehenden Stauchung der Produkte im Laufe ihrer Übergabe von einem Abschnitt der Fördereinheit zum anderen, je nachdem, welcher von beiden der schnellere ist. Eine Scherung kann hingegen nicht auftreten, denn hierfür ist erforderlich, dass Bänder mit unterschiedlichen Geschwindigkeiten einander gegenüberliegen.According to a more elaborate embodiment, a drive device for the second and the third endless belt can be controlled independently of the rotational speed of the cylinder. With her can be adjusted to the respective thickness of the conveyed product and the resulting speed of the first endless belt speed of the second and third band, here slight differences between an optimal under the aspect of the deformation-free conveying of the products speed of the second and third band and their actual speed can be tolerated much earlier than in the above-described conveyor unit with two endless belts. In fact, in the case of the conveying unit according to the invention, such a deviation merely leads to a slight tensile stress or a temporary compression of the products in the course of their transfer from one section of the conveying unit to the other, depending on which of the two is faster. Shear, on the other hand, can not occur because it requires bands of different speeds facing each other.

Die optimale Geschwindigkeit muss gleich der Geschwindigkeit des ersten Endlosbandes oder der Umfangsgeschwindigkeit des Zylinders sein, oder sie muss zwischen diesen beiden Werten liegen. Insbesondere kann als optimale Geschwindigkeit der Mittelwert der Geschwindigkeiten des ersten Bandes und des Zylinders angenommen werden. Dies entspricht einer Lage der neutralen Faser des Produkts, d. h. einer fiktiven Linie des Produkts, die beim Fördern auf dem Zylinder weder gestreckt noch gestaucht wird, exakt in der Mitte des Produkts.The optimum speed must be equal to the speed of the first endless belt or the peripheral speed of the cylinder, or it must be between these two values. In particular, the average speed of the first band and the cylinder can be assumed as the optimum speed. This corresponds to a position of the neutral fiber of the product, ie a fictive line of the product Product that is neither stretched nor compressed when conveying on the cylinder, exactly in the middle of the product.

Diese Antriebseinrichtung ist zweckmäßigerweise einer Regeleinrichtung zugeordnet, die auf eine Angleichung der Geschwindigkeiten des zweiten und des dritten endlosen Bandes an die optimale Geschwindigkeit hinwirkt. Diese Regeleinrichtung regelt vorzugsweise die Geschwindigkeit des zweiten Bandes mit einem variierbaren Proportionalitätsfaktor proportional zur Drehgeschwindigkeit des Zylinders.This drive device is expediently associated with a control device which acts to equalize the speeds of the second and third endless belt to the optimum speed. This control device preferably controls the speed of the second belt with a variable proportionality factor proportional to the rotational speed of the cylinder.

Durch Anpassen des Proportionalitätsfaktors in Abhängigkeit von der Dicke der geförderten Gegenstände wird deren Streck- oder Stauchbeanspruchung beim Übergang von einem Abschnitt der Förderstrecke zum anderen minimiert.By adjusting the proportionality factor as a function of the thickness of the conveyed objects, their stretching or compressive stress is minimized during the transition from one section of the conveying path to the other.

Um den Proportionalitätsfaktor festzulegen, kann die Regeleinrichtung an einen Sensor zum Messen der Geschwindigkeit des ersten Bandes gekoppelt sein. Dessen Geschwindigkeit variiert linear mit der Dicke der geförderten Gegenstände; durch eine einfache Angleichung der Geschwindigkeit aller Bänder ist die Freiheit von Streck- oder Stauchbelastungen zu erreichen.To determine the proportionality factor, the controller may be coupled to a sensor for measuring the speed of the first band. Its speed varies linearly with the thickness of the conveyed objects; By simply adjusting the speed of all belts, the freedom of stretching or compression loads can be achieved.

Eine weitere Möglichkeit ist, einen Sensor zum Erfassen einer Dicke der Gegenstände an die Regeleinrichtung zu koppeln. Ein solcher Sensor kann insbesondere noch vor dem Eingang der Fördereinheit angeordnet sein, um die Bandgeschwindigkeiten der Fördereinheit an eine geänderte Dicke anpassen zu können, noch bevor der Gegenstand, an dem die Dickenmessung durchgeführt wurde, die Fördereinheit erreicht.Another possibility is to couple a sensor for detecting a thickness of the articles to the control device. Such a sensor can in particular be arranged before the entrance of the conveyor unit in order to be able to adapt the conveyor speeds of the conveyor unit to a changed thickness, even before the object on which the thickness measurement was carried out reaches the conveyor unit.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment is shown in the drawing and will be described in more detail below.

Die einzige Zeichnung zeigt einen schematischen Schnitt durch eine Fördereinheit.The single drawing shows a schematic section through a conveyor unit.

Die Signaturen bestehen daher aus einer unterschiedlichen Anzahl von übereinanderliegenden Papierbogen, die nicht fest zusammengehalten sind und daher an allen vier Seiten offen sind.The conveyor unit is arranged following a cutting unit formed from a knife cylinder 02 and an opposite grooved cylinder 03, with a in one overlying, not shown in the drawing superstructure with the aid of several rotating slitter cut into strands and superimposed web of material 01, z. B. a paper web 01, is cut into individual signatures. The signatures therefore consist of a different number of superimposed sheets of paper, which are not firmly held together and are therefore open on all four sides.

Die Strecke, entlang der die Signaturen in der Fördereinheit gefördert werden, kann in zwei Abschnitte untergliedert werden, einen ersten Abschnitt 08, in dem die Signaturen zwischen zwei Endlosbändern 06; 05, hier als zweites bzw. drittes Endlosband 06; 05 bezeichnet, zusammengedrückt transportiert werden, und einen zweiten Abschnitt 09, in dem sie zwischen einem ersten Endlosband 04 und einem Zylinder 07, z. B. einem Sammelzylinder 07 einer Rotationsdruckmaschine, transportiert werden.The distance along which the signatures are conveyed in the conveyor unit can be divided into two sections, a first section 08, in which the signatures between two endless belts 06; 05, here as the second or third endless belt 06; 05 referred compressed, and a second section 09, in which they between a first endless belt 04 and a cylinder 07, z. B. a collecting cylinder 07 a rotary printing machine to be transported.

In einer Übergangszone zwischen dem ersten Abschnitt 08 und dem zweiten Abschnitt 09 sind die Signaturen auf einer dem Sammelzylinder 07 zugewandten Seite durch eine keilförmige Zunge 17 geführt. Eine untere Umlenkwalze 18 des dritten Endlosbandes 05 ist um eine Achse 19 unter Aufrechterhaltung der Spannung des dritten Endlosbandes 05 schwenkbar montiert und ermöglicht so einen Zugang zu der Zunge 17, um diese auszutauschen oder zu warten.In a transition zone between the first section 08 and the second section 09, the signatures are guided on a side facing the collecting cylinder 07 by a wedge-shaped tongue 17. A lower deflecting roller 18 of the third endless belt 05 is pivotally mounted about an axis 19 while maintaining the tension of the third endless belt 05, thus allowing access to the tongue 17 to replace or maintain it.

Der Sammelzylinder 07 ist durch einen in der Zeichnung nicht dargestellten Motor angetrieben. Das erste Endlosband 04, das im zweiten Abschnitt 09 den Sammelzylinder 07 auf einem Winkelbereich von etwa 180° umschlingt, wird von dem Sammelzylinder 07 durch Reibung angetrieben. Wenn Signaturen im zweiten Abschnitt 09 gefördert werden, übertragen diese die Antriebskraft vom Sammelzylinder 07 auf das erste Endlosband 04.The collecting cylinder 07 is driven by a motor, not shown in the drawing. The first endless belt 04, which wraps around the collecting cylinder 07 in the second section 09 over an angular range of approximately 180 °, is driven by the collecting cylinder 07 by friction. When signatures are conveyed in the second section 09, they transmit the driving force from the collecting cylinder 07 to the first endless belt 04.

Dabei haben die vom Sammelzylinder 07 abgewandten Außenseiten der Signaturen infolge ihres größeren Abstands vom Drehmittelpunkt des Sammelzylinders 07 eine geringfügig größere Bahngeschwindigkeit als die Mantelfläche des Sammelzylinders 07 selber, wobei der Geschwindigkeitsunterschied proportional zur Dicke der Signaturen ist. Die Geschwindigkeit des ersten Endlosbandes 04 passt sich daher bei wechselnder Dicke der Signaturen automatisch an.In this case, facing away from the collecting cylinder 07 outer sides of the signatures due to their greater distance from the center of rotation of the collecting cylinder 07 a slightly greater line speed than the lateral surface of the collecting cylinder 07 itself, the speed difference is proportional to the thickness of the signatures. The speed of the first endless belt 04 therefore adapts automatically with changing thickness of the signatures.

Das zweite Endlosband 06 und das dritte Endlosband 05 sind mit gleicher Geschwindigkeit über ein Zwischenrad 11 gemeinsam von einer Antriebseinrichtung 12, z. B. einem frequenzgeregelten Motor 12 angetrieben. So kann es auch während des Transports der Signaturen im ersten Abschnitt 08 zu keinerlei Scherung kommen. Die Geschwindigkeit des Motors 12 ist von einer Regeleinrichtung 13 geregelt, deren Aufgabe es ist, die Bahngeschwindigkeiten der zwei Endlosbänder 05; 06 auf einem geeigneten, an die Transportgeschwindigkeit der Signaturen im Abschnitt 09 angepassten Wert zu halten und so zu vermeiden, dass die Blätter der Signaturen bei ihrem Übergang vom ersten Abschnitt 08 in den zweiten Abschnitt 09 gegeneinander verschoben oder gestaucht werden, und die Signaturen so unansehnlich oder unbrauchbar werden.The second endless belt 06 and the third endless belt 05 are connected at the same speed via an intermediate 11 together by a drive device 12, for. B. a frequency-controlled motor 12 driven. Thus, it can also come during the transport of the signatures in the first section 08 to any shear. The speed of the motor 12 is controlled by a control device 13, whose task is the web speeds of the two endless belts 05; 06 on a suitable, adapted to the transport speed of the signatures in the section 09 value and to avoid so that the leaves of the signatures are moved or compressed against each other in their transition from the first section 08 in the second section 09, and the signatures so unsightly or become unusable.

Eine erste Möglichkeit, die Bahngeschwindigkeiten der drei Endlosbänder 04; 05; 06 zu steuern ist, die Geschwindigkeit des zweiten und dritten Endlosbandes 06 bzw. 05 an die des ersten Endlosbandes 04 anzugleichen, so dass eine Signatur, die vom ersten Abschnitt 08 in den zweiten Abschnitt 09 der Förderstrecke übergeben wird, zumindest an ihrer dem dritten und ersten Endlosband 05 bzw. 04 zugewandten Seite keinerlei Streck- oder Stauchbelastungen ausgesetzt ist. Da, wie oben beschrieben, die Geschwindigkeit des ersten Endlosbandes 04 von der Geschwindigkeit des Sammelzylinders 07 und der Dicke der zu fördernden Signaturen abhängig ist, ist eine aktive Regelung der Geschwindigkeit für die diversen Endlosbänder erforderlich.A first possibility, the web speeds of the three endless belts 04; 05; 06 is to equalize the speed of the second and third endless belt 06 and 05 to that of the first endless belt 04, so that a signature that is passed from the first section 08 in the second section 09 of the conveyor line, at least at its the third and first endless belt 05 or 04 facing side is exposed to any stretching or compression loads. As described above, since the speed of the first endless belt 04 depends on the speed of the collecting cylinder 07 and the thickness of the signatures to be conveyed, active control of the speed is required for the various endless belts.

Zu diesem Zweck ist die Regeleinrichtung 13 gemäß einer ersten Ausgestaltung der Erfindung mit zwei Geschwindigkeitssensoren für die Bahngeschwindigkeit des dritten und des zweiten Endlosbandes 05 bzw. 06 verbunden und wirkt auf eine Angleichung dieser Bahngeschwindigkeiten hin. Die Geschwindigkeitssensoren können z. B. Drehwinkelgeber sein, die jeweils an einer Umlenkwalze 14 bzw. 16 des dritten bzw. zweiten Endlosbandes 05; 06 angeordnet sind und die jedes Mal, wenn die Umlenkwalze 14; 16 einen festgelegten Drehwinkel zurückgelegt hat, einen Impuls an die Regeleinrichtung 13 liefern. Vorzugsweise sind diese Drehwinkelsensoren baugleich und sind an Umlenkwalzen 14; 16 mit gleichem Radius montiert. In diesem Fall kann die Regeleinrichtung 13 eine identische Bahngeschwindigkeit der Endlosbänder 05; 06 dadurch gewährleisten, dass sie einen konstanten, vorzugsweise verschwindenden Phasenversatz zwischen den von den zwei Sensoren gelieferten Impulsen aufrechterhält. Die Geschwindigkeit des zweiten und dritten Endlosbandes 06; 05 ist dann proportional zu der Geschwindigkeit des Sammelzylinders 07, wobei der Proportionalitätsfaktor durch die Dicke der zwischen dem Sammelzylinder 07 und dem ersten Endlosband 04 geförderten Signaturen bestimmt ist.For this purpose, the control device 13 is connected according to a first embodiment of the invention with two speed sensors for the web speed of the third and second endless belt 05 and 06 and acts on an approximation of these web speeds. The speed sensors can z. B. rotary encoder, each at a guide roller 14 and 16 of the third and second endless belt 05; 06 are arranged and each time when the guide roller 14; 16 has traveled a predetermined angle of rotation, provide a pulse to the controller 13. Preferably, these rotation angle sensors are identical and are at deflection rollers 14; 16 mounted with the same radius. In this case, the control device 13 an identical web speed of the endless belts 05; 06 ensure that it maintains a constant, preferably vanishing phase offset between the pulses supplied by the two sensors. The speed of the second and third endless belts 06; 05 is then proportional to the speed of the collecting cylinder 07, wherein the proportionality factor is determined by the thickness of the promoted between the collecting cylinder 07 and the first endless belt 04 signatures.

Eine andere Möglichkeit, die Geschwindigkeit des zweiten Endlosbandes 06 zu regeln, ist, die Regeleinrichtung 13 einerseits mit einem Sensor für die Geschwindigkeit des ersten Endlosbandes 04 oder die Drehgeschwindigkeit des Sammelzylinders 07 und andererseits mit einem Sensor für die Dicke der zu transportierenden Signaturen zu verbinden, wobei dann die Regeleinrichtung 13 eine vom Motor 12 einzuhaltende Geschwindigkeit aus der gemessenen Geschwindigkeit, korrigiert durch einen von der gemessenen Dicke abhängigen Proportionalitätsfaktor, berechnet. Ein Sensor für die Dicke der Signaturen oder eine dazu proportionale Größe kann an einer weitgehend beliebigen Stelle in der Fördereinheit selbst oder besser noch vor Beginn der Fördereinheit an der Materialbahn 01 angeordnet sein.Another way to control the speed of the second endless belt 06 is to connect the control device 13 on the one hand with a sensor for the speed of the first endless belt 04 or the rotational speed of the collecting cylinder 07 and on the other hand with a sensor for the thickness of the signatures to be transported wherein the controller 13 then calculates a speed to be maintained by the engine 12 from the measured speed corrected by a proportionality factor dependent on the measured thickness. A sensor for the thickness of the signatures or a size proportional thereto can be arranged on the material web 01 at a largely arbitrary point in the conveyor unit itself or better still before the start of the conveyor unit.

Denkbar ist auch, dass eine Bedienungsperson eine bekannte Dicke der Signaturen, ihre Blattzahl und Flächengewicht des Papiers oder eine beliebige äquivalente Kombination von Parametern an einem Regler der Regeleinrichtung 13 einstellt.
An einem solchen Regler kann eine Bedienungsperson auch nachträgliche Korrekturen vornehmen, wenn sie erkennt, dass die von der Fördereinheit geförderten Signaturen geschert sind.It is also conceivable for an operator to set a known thickness of the signatures, their number of sheets and grammage of the paper or any equivalent combination of parameters on a controller of the control device 13.
At such a controller, an operator can also make subsequent corrections, if they recognize that subsidized by the conveyor unit signatures are sheared.

Einer vereinfachten zweiten Ausgestaltung zufolge ist das Zwischenrad 11, das die zwei Endlosbänder 05; 06 gemeinsam antreibt, über ein (nicht dargestelltes) Getriebe mit fester Übersetzung an die Drehung des Sammelzylinders 07 gekoppelt. Die Übersetzung des Getriebes ist so gewählt, dass die Bahngeschwindigkeit der zwei Endlosbänder 05; 06 gleich der Umfangsgeschwindigkeit des Sammelzylinders 07 ist. Bei dieser Ausgestaltung läuft das dritte Endlosband 05 geringfügig langsamer als das erste Endlosband 04, das im Anschluss daran in der Förderstrecke angeordnet ist. In Folge der Gleichheit der Bahngeschwindigkeiten der Endlosbänder 05; 06 mit der Umfangsgeschwindigkeit des Sammelzylinders 07 ist eine Signatur am Übergang von Abschnitt 08 zu Abschnitt 09 zumindest an ihrer dem zweiten Endlosband 06 und dem Sammelzylinder 07 zugewandten Seite keinerlei Streck- oder Stauchkräften ausgesetzt. Eine geringfügige Streckbeanspruchung kann an der gegenüberliegenden Seite des Substrats in Kontakt mit den Endlosbändern 05; 04 auftreten, da das Endlosband 04 sich geringfügig schneller bewegt als das Endlosband 05.According to a simplified second embodiment, the intermediate wheel 11, which is the two endless belts 05; 06 drives together, coupled via a (not shown) transmission with a fixed ratio to the rotation of the collecting cylinder 07. The gear ratio is chosen so that the web speed of the two endless belts 05; 06 is equal to the peripheral speed of the collecting cylinder 07. In this embodiment, the third endless belt 05 runs slightly slower than the first endless belt 04, which is subsequently arranged in the conveying path. As a result of the equality of the web speeds of the endless belts 05; 06 with the peripheral speed of the collecting cylinder 07 is a signature at the transition from section 08 to section 09 exposed at least on their the second endless belt 06 and the collecting cylinder 07 side facing any stretching or compression forces. A slight stretching stress may be applied to the opposite side of the substrate in contact with the endless belts 05; 04 occur because the endless belt 04 moves slightly faster than the endless belt 05th

Bei geringen Dicken der Signaturen und infolgedessen geringen Unterschieden in den Geschwindigkeiten des ersten Endlosbandes 04 und der übrigen Endlosbänder 05; 06 kann eine solche Streckbelastung hinnehmbar sein. Wenn jedoch die Dicke der Signaturen zu groß und damit die Geschwindigkeitsdifferenz zwischen dem Sammelzylinder 07 und dem ersten Endlosband 04 zu groß wird, kann es bei der Übergabe einer Signatur zwischen Abschnitten 08 und 09 zu einer geringfügigen Scherung im Laufe der Übergabe zwischen den zwei Abschnitten 08; 09 kommen.With small thicknesses of the signatures and consequently small differences in the speeds of the first endless belt 04 and the other endless belts 05; 06, such a stretching load can be acceptable. However, if the thickness of the signatures becomes too large and thus the speed difference between the collecting cylinder 07 and the first endless belt 04 becomes too large, a handover of a signature between sections 08 and 09 may result in a slight shearing in the course of transfer between the two sections 08 ; 09 come.

Im Gegensatz dazu wirkt bei der oben beschriebenen ersten Ausgestaltung lediglich eine Stauchkraft auf die Signaturen im Moment der Übergabe. Diese kann nicht zu einem Verrutschen einzelner Blätter der Signaturen führen, so dass bei der Verarbeitung dicker Signaturen der technisch aufwendigeren ersten Ausgestaltung der Vorzug gegenüber der einfachen und preiswerten zweiten gebühren mag.In contrast, acts in the first embodiment described above only an upsetting force on the signatures at the moment of transfer. This can not lead to slippage of individual sheets of signatures, so that when processing thick signatures of the technically complex first embodiment of preference over the simple and inexpensive second charges may.

Selbstverständlich kann als Fördergeschwindigkeit der Endlosbänder 05; 06 des ersten Abschnitts 08 im Prinzip jede beliebige Geschwindigkeit eingestellt werden, die zwischen der Umfangsgeschwindigkeit des Sammelzylinders 07 und der Bahngeschwindigkeit des ersten Endlosbandes 04 liegt. Wählt man z. B. als Bahngeschwindigkeit des ersten Abschnitts 08 den Mittelwert von Umfangsgeschwindigkeit des Sammelzylinders 07 und Bahngeschwindigkeit des Endlosbandes 04, so wirkt an einer dem Sammelzylinder 07 zugewandten Oberfläche der Signatur bei der Übergabe zum zweiten Abschnitt 09 eine geringfügige Stauchung, während die gegenüberliegende, den Endlosbändern 05, 04 zugewandte Oberfläche der Signatur gestreckt wird.Of course, as the conveying speed of the endless belts 05; 06 of the first section 08 in principle, any speed can be set, which is between the peripheral speed of the collecting cylinder 07 and the web speed of the first endless belt 04. If you choose z. B. as the web speed of the first section 08, the average of peripheral speed of the collecting cylinder 07 and web speed of the endless belt 04, acting on a collecting cylinder 07 surface facing the signature at the transfer to the second section 09 a slight compression, while the opposite, the endless belts 05 , 04 facing surface of the signature is stretched.
