Abstract

The apparatus has an input pocket into which a stack of sheets is inserted. At least the sheet to be picked from the stack by the picking device is transported by means of a feed device to a picking device which then picks one sheet from the stack at a time. To improve singling quality, a presingling device is provided which first transports only part of the stack to the picking device. In order to ensure that stacks of different-sized sheet material are singled reliably, an aligning device is provided which transports at least the sheet to be picked from the stack in the direction of a defined stop and thus aligns the sheet against said stop. The aligning device preferably cooperates alternatingly with the feed device. To increase singling reliability, a pressure plate is provided in the presingling device for acting upon the presingled partial stack with a certain pressure.

Description

Die Erfindung betrifft eine Vorrichtung zum Vereinzeln von Blattgut, wie z.B. Banknoten oder Wertpapiere, aus einem Stapel.The invention relates to a device for separating sheet material, such as e.g. Banknotes or securities from a stack.

Eine solche Vorrichtung ist beispielsweise aus der DE-OS 21 51 548 bekannt. Die dort beschriebene Vorrichtung weist ein Eingabefach auf, in das ein Blattgutstapel eingelegt wird. Mittels einer Vorschubeinrichtung wird zumindest das von der Abzugseinrichtung abzuziehende Blatt des Stapels.zu einer Abzugseinrichtung transportiert, die dann jeweils ein Blatt vom Stapel abzieht. Zur Verbesserung der Vereinzelungssicherheit weist die Vorrichtung eine Vorvereinzelungseinrichtung auf, die zunächst lediglich eine Teilmenge des Stapels zur Abzugseinrichtung transportiert.Such a device is known for example from DE-OS 21 51 548. The device described there has an input compartment into which Stack of sheets is inserted. At least by means of a feed device the sheet of the stack to be removed from the removal device a deduction device, which then transports one sheet from the stack subtracts. To improve the separation security, the device has a pre-separation device, initially only a subset of the stack transported to the take-off device.

Ein Nachteil der Vorrichtung besteht darin, daß ein Stapel aus Blattgut unterschiedlicher Größe bzw. Formats nur schlecht vereinzelt werden kann. Um beispielswelse eine der Längskanten des Blattguts auf einer Seite des Stapels parallel zur Transportrichtung auszurichten, muß der Bediener den Stapel vor dem Einlegen in das Eingabefach beispielsweise auf einer Ebene aufstoßen, um die gewünschte Ausrichtung zu bewirken.A disadvantage of the device is that a stack of different sheets Size or format is difficult to separate. For example, one of the long edges of the leaf material on one side of the The operator must align the stack parallel to the transport direction Stack on one level, for example, before loading it into the input tray belch to achieve the desired orientation.

Aus NL-A 8 201 560 ist eine Vereinzelungsvorrichtung bekannt, die eine Vorschubeinrichtung und schräg zur Vereinzelungsrichtung ausgerichtete Rollen aufweist, um eine Querkomponente in Richtung auf eine seitliche Anlagefläche zu bewirken und auf diese Weise das zu vereinzelnde Blatt auszurichten. Sobald jedoch dieses Blatt von der Abzugseinrichtung erfaßt ist, ist mit dieser Vorrichtung kein Ausrichten des Blattes mehr möglich. Das gilt auch für die aus der EP-A 21 397 bekannte Vereinzelungsvorrichtung, bei welcher mittels einer senkrecht zur Abzugsrichtung wirkenden Schuppungsrolle das zu fördernde Blatt in den Eingriffsbereich zweier angetriebener konischer Abzugswalzen geschoben wird. From NL-A 8 201 560 a separating device is known, the one Feed device and aligned obliquely to the separation direction Rollers has a transverse component towards a lateral To effect contact surface and in this way the sheet to be separated align. However, once this sheet is caught by the trigger is no longer possible to align the sheet with this device. The also applies to the separating device known from EP-A 21 397, in which by means of a scaling roller acting perpendicular to the pull-off direction the sheet to be conveyed into the engagement area of two driven conical take-off rollers is pushed.

Ausgehend davon liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum Vereinzeln von Blattgut von einem Stapel vorzuschlagen, die auch einen Stapel aus Blattgut unterschiedlichen Formats und unterschiedlicher Qualität sicher vereinzelt.Proceeding from this, the object of the invention is a device To propose sheet material from a stack, which also a stack of sheet material of different formats and different Quality certainly isolated.

Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst.This object is solved by the features of the main claim.

Der Grundgedanke der Erfindung besteht im wesentlichen darin, eine Ausrichteinrichtung vorzusehen, die zumindest das von der Abzugseinrichtung abzuziehende Blatt des Stapels in Richtung eines definierten Anschlags transportiert, so daß das Blatt gegen diesen Anschlag ausgerichtet wird. Dabei wirkt die Ausrichteinrichtung alternierend mit einer Vorschubeinrichtung zusammen, so daß die Vorschubeinrichtung und die Ausrichteinrichtung zu unterschiedlichen Zeiten auf das abzuziehende Blatt des Stapels einwirken. Dieses wird dann wechselweise in Ausrichtungsrichtung und Transportrichtung transportiert, bis es die Abzugseinrichtung erreicht.The basic idea of the invention consists essentially in an alignment device to provide at least that of the fume cupboard sheet of the stack to be pulled off in the direction of a defined stop transported so that the sheet is aligned against this stop. there the alignment device acts alternately with a feed device together so that the feed device and the alignment device at different times on the sheet of the stack to be peeled off act. This is then alternately in the direction of alignment and Transport direction transported until it reaches the trigger device.

Vorteil der Erfindung ist es, daß jedes Blatt unabhängig von seinem Format mit einer Kante parallel zur Transportrichtung ausgerichtet wird und sich somit beim Abzug in einem definierten Zustand befindet.The advantage of the invention is that each sheet is independent of its format is aligned with an edge parallel to the direction of transport and itself thus in a defined state when the print is made.

Vorzugsweise wird eine Vorvereinzelungseinrichtung mit einer Andruckeinrichtung vorgesehen, die einen vorvereinzelten Teilstapel mit einem bestimmten Druck beaufschlagt, Hierdurch wird erreicht, daß das von der Abzugseinrichtung abzuziehende Blatt sich in einem definierten Zustand befindet, der nicht von der Anzahl der Blätter im Teilstapel abhängt. Durch eine Optimierung der Abzugseinrichtung auf den definierten Zustand des abzuziehenden Blattes ist eine optimale Vereinzelungssicherheit gewährleistet. A pre-separation device with a pressure device is preferred provided that a pre-isolated sub-stack with a certain Pressurized, this ensures that the trigger device sheet to be removed is in a defined state, which does not depend on the number of sheets in the partial stack. By a Optimization of the trigger device to the defined state of the trigger Optimal separation security is guaranteed.

Die Fig. 1 zeigt die Seitenansicht einer Ausführungsform der Erfindung. Das Blattgut befindet sich hier in einem Stapel 10 in einem Eingabefach, das aus einer Grundplatte 20, einer Rückhalteplatte 21 und einer Auflageplatte 22 gebildet wird.1 shows the side view of an embodiment of the invention. The Sheet material is here in a stack 10 in an input tray that is made of a base plate 20, a retaining plate 21 and a support plate 22 is formed.

Zum Transport der Blätter ist eine Vorschubeinrichtung vorgesehen, die mehrere im Reibkontakt mit dem Blattgut stehende Bewegungselemente aufweisen kann. Als Bewegungselement sind in der Fig. 1 zum einen hintere Nockenräder 30 vorgesehen, die zusammen mit Antriebsrädern 31 auf einer Achse 32 angeordnet sind. Um die hinteren Nockenräder 30 ist ein Reibriemen 33 gelegt. Weiterhin ist ein vorderes Nockenrad 40 vorgesehen, das analog mit einem Antriebsrad 41 auf einer Achse 42 angeordnet ist. In einem gewissen Abstand zum Nockenrad 40 ist ein Gegenrad 43 auf einer Achse 44 angeordnet. Um das Nockenrad 40 und das Gegenrad 43 ist ein Reibriemen 45 gelegt.A feed device is provided for transporting the sheets several movement elements in frictional contact with the sheet material can have. As a moving element in FIG. 1 are rear Cam wheels 30 are provided, which together with drive wheels 31 on a Axis 32 are arranged. There is a friction belt around the rear cam wheels 30 33 laid. A front cam gear 40 is also provided is arranged analogously with a drive wheel 41 on an axis 42. In one a certain distance from the cam gear 40 is a counter gear 43 on an axis 44 arranged. Around the cam gear 40 and the counter gear 43 is a friction belt 45 laid.

Durch die Verwendung von Reibriemen 33 und 45 wird gewährleistet, daß eine relativ große Reibfläche zur Wechselwirkung mit dem Blattgut zur Verfügung steht, da die Reibriemen 33 und 45 eine Länge aufweisen, die größer dem Umfang des jeweiligen Nockenrades ist. Durch die Drehung der Nokkenräder 30 und 40 bewegen sich die Reibriemen 33 und 45 über die Nokkenräder, so daß jeweils eine andere Stelle des Reibriemens 33 und 45 mit dem Blattgut wechselwirkt. Der durch die Reibung entstehende Verschleiß wird somit gleichmäßig über die Reibriemen 33 und 45 verteilt. Hierdurch kann eine relativ hohe Standzeit der Reibriemen 33 und 45 erreicht werden, so daß diese nur selten ausgetauscht werden müssen. The use of friction belts 33 and 45 ensures that a relatively large friction surface for interaction with the sheet material is available stands because the friction belts 33 and 45 have a length that is greater the circumference of the respective cam wheel. By turning the cam wheels 30 and 40 the friction belts 33 and 45 move over the cam wheels, so that each have a different location of the friction belt 33 and 45 the leaf material interacts. The wear caused by the friction is thus evenly distributed over the friction belts 33 and 45. Hereby a relatively long service life of the friction belts 33 and 45 can be achieved, so that they rarely need to be replaced.

In einer Vorrichtung, die eine verhältnismäßig geringe Anzahl von Blättern in einer vorgegebenen Zeiteinheit vereinzelt und bei der damit der Verschleiß durch Abrieb geringer ist, können auch Nockenräder oder anders gestaltete Räder eingesetzt werden, bei denen lediglich an deren Umfang zumindest teilweise ein Reibelement vorgesehen ist.In a device that has a relatively small number of sheets isolated in a given unit of time and thus the wear is less by abrasion, can also cam wheels or otherwise designed wheels are used, where only the scope at least partially a friction element is provided.

Optional kann ein Antrieb 46 vorgesehen werden, der zum Antrieb des Reibriemens 45 dient. Das Nockenrad 40 wird hierbei so ausgestaltet, daß der Reibriemen 45 unabhängig von der Stellung des Nockenrades 40 über dieses gleiten kann. Durch diese Maßnahme kann die Transportgeschwindigkeit bei der Vereinzelung des Blattguts unabhängig von der Wechselwirkungszeit des Reibriemens 45 mit dem Blattgut geregelt werden. Die Wechselwirkungszeit wird im wesentlichen durch die Umdrehungsgeschwindigkeit des Nockenrades 40 bestimmt.Optionally, a drive 46 can be provided which drives the Friction belt 45 is used. The cam wheel 40 is designed so that the friction belt 45 regardless of the position of the cam gear 40 this can slide. This measure can reduce the transport speed when separating the sheet material regardless of the interaction time of the friction belt 45 can be regulated with the sheet material. The interaction time is essentially determined by the speed of rotation of the cam wheel 40 determined.

Um den Verschleiß der Reibriemen 33 und 45 weiter zu vermindern, können die Nockenräder 30 und 40 zumindest teilweise gefedert gelagert sein. Hierdurch wird erreicht, daß der Andruck der Reibriemen 33 und 45 gegen das Blattgut nach oben begrenzt ist.In order to further reduce the wear of the friction belts 33 and 45 the cam wheels 30 and 40 are at least partially spring-mounted. Hereby is achieved that the pressure of the friction belts 33 and 45 against the Sheets are capped.

Die Begrenzung des Andrucks ist insbesondere bei hohen Stapeln 10 wirksam. Diese Begrenzung des Andrucks verhindert bei hohen Stapeln 10 zu große Vorschubkräfte, die zu vermehrten Doppelabzügen führen können. Außerdem können die Reibriemen 33 und 45 bei Berührung durch den Benutzer nachgeben, was die Verletzungsgefahr verringert.The limitation of the pressure is particularly effective with high stacks 10. This limitation of the pressure prevents 10 at high stacks large feed forces that can lead to increased double deductions. In addition, the friction belts 33 and 45 can be touched by the user give way, which reduces the risk of injury.

Die hinteren Nockenräder 30 werden vorzugsweise mit einer elliptischen Außenkontur ausgeführt. Ein über zwei elliptische Nockenräder 30 gelegte Reibriemen 33 hat in jeder Stellung der Nockenräder 30 die gleiche Länge. The rear cam gears 30 are preferably elliptical Outer contour executed. One placed over two elliptical cam wheels 30 The friction belt 33 has the same length in each position of the cam wheels 30.

Damit läßt sich ohne Längenänderung des Reibriemens 33 ein relativ großer Hub der Nocken erreichen.This allows a relatively large without changing the length of the friction belt 33 Reach cam stroke.

Weiterhin ist eine Ausrichteinrichtung vorgesehen. Diese weist mehrere im Reibkontakt mit dem Blatt stehende Bewegungselemente beispielsweise in Form von Nockenrädern 50 auf, die mit einem Antriebsrad 51 auf einer Achse 52 angeordnet sind. Analog zum Gegenrad 43 des vorderen Nockenrads 40 sind auch hier in bestimmtem Abstand zu den Nockenrädern 50 eine entsprechende Anzahl von Gegenrädern 53 auf einer Achse 54 angeordnet. Um jeweils ein Nockenrad 50 und ein Gegenrad 53 ist ein Reibriemen 55 gelegt. Auch hier können die Achse 54 und somit auch die Reibriemen 55 optional von einem Antrieb 56 angetrieben werden.An alignment device is also provided. This has several in Frictional contact with the moving elements, for example in Form of cam wheels 50 on, with a drive wheel 51 on an axis 52 are arranged. Analogous to the counter gear 43 of the front cam gear 40 are also a corresponding one at a certain distance from the cam wheels 50 Number of counter wheels 53 arranged on an axis 54. Around In each case a cam wheel 50 and a counter wheel 53, a friction belt 55 is placed. Here, too, the axis 54 and thus also the friction belts 55 can be optional are driven by a drive 56.

Die Nockenräder 30, 40 und 50 werden bevorzugt von einem einzelnen Nokkenradantrieb 60 angetrieben. Der Nockenradantrieb 60 treibt ein Antriebsrad 61, das auf einer Achse 62 angeordnet ist. Mittels Antriebsriemen 63, 64 und 65 werden die Nockenräder 30, 40 und 50 über die zugehörigen Antriebsräder 31, 41 und 51 angetrieben.The cam gears 30, 40 and 50 are preferably driven by a single cam gear 60 driven. The cam wheel drive 60 drives a drive wheel 61, which is arranged on an axis 62. By means of drive belts 63, 64 and 65, the cam wheels 30, 40 and 50 via the associated drive wheels 31, 41 and 51 driven.

Die Form der Nockenräder 30, 40 und 50 ist so gewählt, daß deren Nocken um einen bestimmten Betrag durch die Auflageplatte 22 in das Eingabefach hineinragen, so daß die Reibriemen 33, 45 und 55 zumindest mit dem abzuziehenden Blatt 11 des Stapels 10 in Berührung kommen.The shape of the cam wheels 30, 40 and 50 is chosen so that their cams by a certain amount through the platen 22 into the input tray protrude so that the friction belts 33, 45 and 55 at least with the one to be removed Sheet 11 of the stack 10 come into contact.

Die Antriebsräder 31, 41 und 51 der Nockenräder 30, 40 und 50 sind so dimensioniert, daß zum einen die Nocken der Nockenräder 30 und 40 und zum anderen die Nocken der Nockenräder 50 gleichzeitig durch die Auflageplatte 22 treten. Die Nocken der Nockenräder 30 und 40 treten bevorzugt zeitversetzt mit einer konstanten Phasenverschiebung zu den Nocken der Nockenräder 50 durch die Auflageplatte 22, so daß die Nocken der Nockenräder 30 und 40 der Vorschubeinrichtung und die Nocken der Nockenräder 50 der Ausrichteinrichtung alternierend zumindest auf das abzuziehende Blatt 11 des Stapels 10 einwirken.The drive wheels 31, 41 and 51 of the cam wheels 30, 40 and 50 are dimensioned so that on the one hand the cams of the cam wheels 30 and 40 and on the other hand, the cams of the cam wheels 50 simultaneously through the support plate 22 kick. The cams of the cam wheels 30 and 40 occur preferentially delayed with a constant phase shift to the cams of the Cam wheels 50 through the platen 22 so that the cams of the cam wheels 30 and 40 of the feed device and the cams of the cam wheels 50 of the alignment device alternating at least with the one to be removed Act on sheet 11 of stack 10.

Alternativ zu den Nockenrädern 30, 40 und 50 können auch runde Räder verwendet werden, die mittels einer geeigneten Mechanik in analoger Weise durch die Auflageplatte 22 treten. Bevorzugt muß auch hier darauf geachtet werden, daß die Räder der Vorschubeinrichtung und die Räder der Ausrichteinrichtung alternierend zumindest auf das abzuziehende Blatt 11 des Stapels 10 einwirken.As an alternative to the cam wheels 30, 40 and 50, round wheels can also be used be used by means of suitable mechanics in an analogous manner step through the platen 22. It is also important to pay attention here that the wheels of the feed device and the wheels of the alignment device alternating at least on the sheet 11 to be removed Act on stack 10.

In Fig. 2 ist eine Prinzipskizze einer Aufsicht auf die Auflageplatte 22, durch die die Nocken der Nockenräder 30, 40 und 50 bevorzugt alternierend hindurchtreten. Die Nockenräder 30 und 40 der Vorschubeinrichtung sind hierbei parallel zu einer Transportrichtung T ausgerichtet. Die Nockenräder 50 sind parallel zu einer Ausrichtungsrichtung A angeordnet.In Fig. 2 is a schematic diagram of a top view of the support plate 22 through which the cams of the cam wheels 30, 40 and 50 preferably pass alternately. The cam wheels 30 and 40 of the feed device are here aligned parallel to a transport direction T. The cam wheels 50 are arranged parallel to an alignment direction A.

Durch die Einwirkung der um die Nockenräder 30 und 40 gelegten Reibriemen 33 und 45 beim Durchtritt der Nocken durch die Auflageplatte 22 wird zumindest das abzuziehende Blatt 11 des Stapels 10 zunächst um eine gewisse Strecke in Richtung der Transportrichtung transportiert. Danach treten die Nocken der Nockenräder 30 und 40 wieder durch die Auflageplatte 22, so daß die Reibriemen 33 und 45 nicht mehr mit dem Blatt 11 wechselwirken. Parallel dazu treten die Nocken der Nockenräder 50 durch die Auflageplatte 22, so daß die Reibriemen 55 zumindest auf das Blatt 11 des Stapels 10 einwirken und dieses in Richtung eines definierten Anschlags transportieren, der hier von der Grundplatte 20 gebildet wird. By the action of the friction belts placed around the cam wheels 30 and 40 33 and 45 when the cams pass through the support plate 22 at least the sheet 11 to be removed from the stack 10 initially by a certain amount Route transported in the direction of transport. Then the kick Cam of the cam wheels 30 and 40 again through the support plate 22, so that the friction belts 33 and 45 no longer interact with the blade 11. In parallel, the cams of the cam wheels 50 pass through the support plate 22, so that the friction belts 55 act at least on the sheet 11 of the stack 10 and transport it in the direction of a defined stop, which is formed here by the base plate 20.

Durch eine geeignete Dimensionierung der Nockenräder 50 und deren Umdrehungsgeschwindigkeit kann gewährleistet werden, daß zumindest das abzuziehende Blatt 11 mit einer Kante parallel zur Transportrichtung T an der Grundplatte 20 ausgerichtet ist, bevor das Blatt von einer Abzugseinrichtung vom Stapel 10 abgezogen wird.By suitable dimensioning of the cam wheels 50 and their speed of rotation can be guaranteed that at least that sheet 11 to be removed with an edge parallel to the transport direction T. the base plate 20 is aligned before the sheet is pulled by a trigger is withdrawn from the stack 10.

Die Fig. 3 zeigt eine zweite Möglichkeit zur Anordnung der Nockenräder 30, 40 und 50, wobei die Nockenräder 30 und 40 der Vorschubeinrichtung um einen bestimmten Winkel zur Transportrichtung T versetzt angeordnet sind, so daß das abzuziehende Blatt 11 nicht nur in Transportrichtung T sondern auch in Ausrichtungsrichtung A transportiert wird. Vorteil hiervon ist es, daß das Blattgut 11 schneller gegen die Grundplatte 20 ausgerichtet wird, da alle Nockenräder 30, 40 und 50 einen gewissen Transport des Blattes 11 in Richtung der Grundplatte 20 bewirken.3 shows a second possibility for arranging the cam wheels 30, 40 and 50, the cam wheels 30 and 40 of the feed device around a certain angle to the transport direction T are arranged offset, so that the sheet 11 to be pulled off not only in the transport direction T but is also transported in the direction of alignment A. The advantage of this is that the sheet material 11 is aligned faster against the base plate 20 because all cam gears 30, 40 and 50 have some transport of the blade 11 in Cause direction of the base plate 20.

Zusätzlich werden die Nockenräder 50 der Ausrichteinrichtung so um einen bestimmten Winkel gedreht angeordnet, daß das abzuziehende Blatt 11 nicht nur in Ausrichtungsrichtung transportiert wird, sondern zusätzlich auch mit einer Komponente beaufschlagt wird, die bezogen auf die Transportrichtung rückwärts gerichtet ist. Vorteil hiervon ist es, daß die Blätter im Falle einer Verklemmung vor oder in der Abzugseinrichtung aus der Abzugseinrichtung zurückgezogen werden. Die Verklemmung kann so in der Regel automatisch beseitigt werden, was wiederum zu einer Erhöhung der Vereinzelungssicherheit führt.In addition, the cam wheels 50 of the alignment device are one certain angle rotated that the sheet 11 to be peeled is not is only transported in the direction of alignment, but also with is applied to a component related to the direction of transport is directed backwards. The advantage of this is that the leaves in the case of a Jamming in front of or in the trigger device from the trigger device be withdrawn. The jam can usually be done automatically be eliminated, which in turn increases the security against separation leads.

Zur weiteren Erhöhung der Vereinzelungssicherheit weist die Vorrichtung eine Vorvereinzelungseinrichtung auf, die in Fig. 1 dargestellt ist und neben der Rückhalteplatte 21 eine Andruckeinrichtung aufweist. Diese besteht aus einem Andruckelement 70, das um eine Achse 71 drehbar gelagert ist. Das Andruckelement 70 kann mittels eines Antriebs 72 und eines Gestänges 73 bewegt werden. Der Antrieb 72 kann beispielsweise als Feder oder als elektrisch ansteuerbarer Schrittmotor oder als Kombination aus beiden ausgeführt sein.To further increase the separation security, the device has a pre-separation device, which is shown in Fig. 1 and next the retaining plate 21 has a pressure device. This consists of a pressure element 70, which is rotatably mounted about an axis 71. The Pressure element 70 can be driven by means of a drive 72 and a linkage 73 be moved. The drive 72 can be, for example, a spring or an electric one controllable stepper motor or a combination of both his.

Um den Reibwiderstand zwischen dem Teilstapel und dem Andruckelement 70 zu verringern, kann das Andruckelement 70 kufenförmig ausgebildet sein oder direkt aus Kufen bestehen. Beim Andruck des Teilstapels treten hierbei lediglich die Kufen in Wechselwirkung mit dem Teilstapel.The frictional resistance between the partial stack and the pressure element To reduce 70, the pressure element 70 may be skid-shaped or consist of skids directly. When pressing the partial stack, this occurs only the runners interact with the partial stack.

Zur Vorvereinzelung ist die den Stapel stützende Rückhalteplatte 21 so dimensioniert, daß zwischen der Rückhalteplatte 21 und der Auflageplatte 22 ein Spalt entsteht, durch den lediglich ein Teilstapel mit einer begrenzten Anzahl von Blättern transportiert werden kann. Die Position des Andruckelements 70 wird so geregelt, daß sie den durch den Spalt tretenden Teilstapel mit einem bestimmten Druck beaufschlagt. Bevorzugt wird der Druck größer gewählt, als der durch das Gewicht des Teilstapels auf die Vorschieb-bzw. Abzugseinrichtung wirkende Druck. Hierdurch kann erreicht werden, daß das zu vereinzelnde Blatt 11 mit einem annähernd konstanten Druck belastet wird, der im wesentlichen unabhängig von der Anzahl der Blätter im Teilstapel ist. Das zu vereinzelnde Blattgut 11 befindet sich somit in einem definierten Zustand, der nicht von der Anzahl der Blätter im Teilstapel abhängig ist An diesen definierten Zustand kann die Abzugseinrichtung optimal angepaßt werden.For pre-separation, the retaining plate 21 supporting the stack is dimensioned such that that between the retaining plate 21 and the platen 22nd a gap is created through which only a partial stack with a limited one Number of sheets can be transported. The position of the pressure element 70 is controlled so that it passes through the partial stack pressurized with a certain pressure. The pressure is preferably greater chosen as the weight of the partial stack on the feed or. Trigger device acting pressure. This can be achieved that the sheet 11 to be separated with an approximately constant pressure is loaded, which is essentially independent of the number of leaves is in the partial stack. The sheet material 11 to be separated is thus in one defined state, which does not depend on the number of sheets in the partial stack The trigger device can optimally depend on this defined state be adjusted.

Alternativ zur Andruckplatte 70 können in der Vorvereinzelungseinrichtung auch Mittel vorgesehen werden, die einen konstanten Luftstrom erzeugen. Dieser Luftstrom wird so geleitet, daß er den Teilstapel mit einem konstanten Druck beaufschlagt. Bei Bedarf können diese Mittel zur Erzeugung eines konstanten Luftstroms auch mit einem Andruckelement 70 mit oder ohne Kufen kombiniert werden.As an alternative to the pressure plate 70, in the pre-separating device means are also provided which generate a constant air flow. This air flow is directed so that it has a constant partial stack Pressure applied. If necessary, these means for generating a constant air flow also with a pressure element 70 with or without Skids can be combined.

Das ausgerichtete und mit bestimmtem Druck beaufschlagte abzuziehende Blatt 11 wird durch eine Abzugseinrichtung vom Stapel 10 abgezogen. Diese weist eine Vereinzelungswalze 80 auf, die durch einen Antrieb 81 über eine Achse 82 angetrieben wird. Bevorzugt wird als Antrieb 81 ein Schrittmotor verwendet, der die Vereinzelungswalze 80 zum Abzug eines Blattes aus der Ruheposition auf die gewünschte Abzugsgeschwindigkeit beschleunigt. Die Vereinzelerwalze 80 weist Reibelemente 83 auf, mittels derer das abzuziehende Blatt 11 vom Stapel 10 abgezogen wird.The aligned one to be subtracted and pressurized Sheet 11 is pulled from stack 10 by a puller. This has a separating roller 80, which is driven by a drive 81 Axis 82 is driven. A stepper motor is preferred as drive 81 used the separating roller 80 for pulling a sheet from the Rest position accelerated to the desired take-off speed. The Singling roller 80 has friction elements 83, by means of which the to be removed Sheet 11 is withdrawn from stack 10.

Der Antrieb 81 wird durch eine hier nicht dargestellte Steuerung gesteuert. In einem ersten Betriebsmodus wird der Antrieb 81 von der Steuerung in konstanten Zeitabständen angesteuert, so daß in konstanten Zeitabständen jeweils ein Blatt vom Stapel 10 durch die Vereinzelungswalze 80 abgezogen wird.The drive 81 is controlled by a controller, not shown here. In a first operating mode, the drive 81 is switched on by the control in controlled at constant intervals, so that at constant intervals one sheet each from the stack 10 is drawn off by the separating roller 80 becomes.

Bevorzugt werden jedoch im Bereich der Abzugseinrichtung Sensoren vorgesehen, deren Meßwerte zur Steuerung des Schrittmotors ausgewertet werden. In einem zweiten Betriebsmodus wird von einem Sensor die Vorder- und/oder Hinterkante des Blattes 11 nach der Vereinzelung detektiert. Die Vereinzelung des nachfolgenden Blattes 12 erfolgt mit einer konstanten Zeitverzögerung nach der Detektion der Hinterkante des abzuziehenden Blattes 11. Hierdurch entsteht zwischen dem abzuziehenden Blatt 11 und dem nachfolgenden Blatt 12 eine Lücke konstanter Größe. Dieser Betriebsmodus ist besonders vorteilhaft bei der Vereinzelung von Blattgut unterschiedlicher Größe, da so der Durchsatz der Blätter optimiert werden kann. Bevorzugt wird der Umfang der Vereinzelungswalze 80 so gewählt, daß dieser gleich der Summe der Länge des kürzesten abzuziehenden Blattes und einer systembedingten minimalen Lücke ist. Hierdurch kann gewährleistet werden, daß auch die kürzesten abzuziehenden Blätter optimal vereinzelt werden können.However, sensors are preferably provided in the area of the extraction device, their measured values for controlling the stepper motor are evaluated become. In a second operating mode, the front and / or trailing edge of the sheet 11 is detected after the singulation. The separation of the following sheet 12 takes place with a constant Time delay after detection of the trailing edge of the to be peeled off Sheet 11. This creates between the sheet to be withdrawn 11 and the following sheet 12 a gap of constant size. This mode of operation is particularly advantageous when differentiating sheet material Size, because the throughput of the sheets can be optimized. The circumference of the separating roller 80 is preferably selected so that it is is equal to the sum of the length of the shortest sheet to be subtracted and a systemic minimal gap. This can ensure be that the shortest leaves to be peeled off optimally can be.

Zur Vermeidung von Doppelabzügen weist die Abzugseinrichtung eine Rückhalteeinrichtung auf. Diese weist gemäß der Ausführungsform in Fig. 1 eine Rückhaltewalze 90 auf, die von einem Antrieb 91 über eine Achse 92 angetrieben wird. Über ein Gegenrad 93, das auf einer Achse 94 angebracht ist, und um die Rückhaltewalze 90 ist ein Reibriemen 95 gelegt. Anders gestaltete Rückhalteeinrichtungen, wie feststehende Rückhalteklötze oder Reibräder sind ebenso möglich.To avoid double deductions, the trigger device has a Restraint device on. According to the embodiment in FIG. 1 a retaining roller 90, which is driven by a drive 91 via an axis 92 is driven. Via a counter wheel 93, which is mounted on an axis 94 and a friction belt 95 is placed around the retention roller 90. Designed differently Restraint devices, such as fixed restraint blocks or Friction wheels are also possible.

Bei der Vereinzelung des Blattguts treibt der Antrieb 91 die Rückhaltewalze 90 gesteuert so an, daß der Reibriemen 95 entgegengesetzt der Transportrichtung T bewegt wird. Die Reibungswirkung des Reibelementes 83 und des Reibriemens 95 sind so gewählt, daß die Reibungswirkung des Reibelements 83 größer ist als die des Reibriemens 95. Beide Reibungswirkungen sind größer als die Reibungswirkung zwischen zwei Blättern 11 und 12. Hierdurch wird gewährleistet, daß lediglich das abzuziehende Blatt 11 vom Reibelement 83 der Vereinzelungswalze 80 erfaßt wird. Das nachfolgende Blatt 12 wird vom Reibriemen 95 der Rückhalteeinrichtung zurückgehalten.When the sheet material is separated, the drive 91 drives the retaining roller 90 controlled so that the friction belt 95 opposite to the transport direction T is moved. The friction effect of the friction element 83 and the friction belt 95 are selected so that the friction effect of the friction element 83 is larger than that of the friction belt 95. Both friction effects are greater than the friction effect between two blades 11 and 12. This ensures that only the sheet 11 to be removed from Friction element 83 of the separating roller 80 is detected. The following Sheet 12 is retained by the friction belt 95 of the restraint.

Zur Beseitigung von Störungen ist es bei Bedarf auch möglich, die Rückhaltewalze 90 gesteuert so anzutreiben, daß der Reibriemen 95 das Blattgut in Transportrichtung T transportiert. Dies kann insbesondere bei der Auflösung von Verklemmungen im Bereich der Vereinzelungswalze 80 vorteilhaft sein. To eliminate malfunctions, it is also possible to use the retention roller 90 controlled to drive so that the friction belt 95 in the sheet Transport direction T transported. This can be particularly the case with the resolution of jams in the area of the separating roller 80 is advantageous his.

Die Rückhalteeinrichtung ist um einen Drehpunkt 96 drehbar gelagert, so daß sich bei der Drehung der Rückhalteeinrichtung um den Drehpunkt 96 der Abstand zwischen der Rückhalteeinrichtung und der Vereinzelungswalze 80 ändert. Die Position der gedrehten Rückhalteeinrichtung ist in der Fig. 1 strichliert dargestellt. Bevorzugt ist die Rückhalteeinrichtung in dieser Position arretierbar, so daß z.B. bei einer nicht automatisch behebbaren Verklemmung von Blattgut ein leichter Zugang zum Blattgut besteht.The restraint device is rotatably mounted about a pivot point 96, so that when the restraint device rotates about the pivot point 96 the distance between the restraint and the separation roller 80 changes. The position of the rotated restraint device is shown in FIG. 1 shown in dashed lines. The retaining device is preferably in this position lockable so that e.g. in the event of a jam that cannot be remedied automatically of sheet material there is easy access to the sheet material.

Um den Verschleiß des Reibriemens 95 gering zu halten, ist auch hier die Länge des Reibriemens größer als der Umfang der Rückhaltewalze 90 gewählt. Um den Andruck des Reibriemens 95 nach oben zu begrenzen, wird die Rückhalteeinrichtung bevorzugt federnd gelagert.In order to keep the wear of the friction belt 95 low, this is also the case here Length of the friction belt selected to be greater than the circumference of the retaining roller 90. In order to limit the pressure of the friction belt 95 upwards, the retaining device is preferably spring-mounted.

Optional kann ein Sensor vorgesehen werden, der die Stellung der Rückhalteeinrichtung detektiert. Abhängig von der detektierten Stellung kann beispielsweise die Betriebsbereitschaft der Vorrichtung durch die Steuerung signalisiert werden.Optionally, a sensor can be provided that detects the position of the restraint device detected. Depending on the detected position, for example the operational readiness of the device by the control be signaled.

Das vom Stapel 10 abgezogene Blattgut 11 kann dann von einem Transportsystem beispielsweise zu weiterbearbeitenden Einrichtungen transportiert werden. Das Transportsystem weist hier Transportriemen 100 und 101 auf, zwischen denen das vom Stapel 10 abgezogene Blattgut transportiert wird. Die Transportriemen 100 werden hier um Umlaufräder 102 umgelenkt, die auf den Achsen 92 und 94 der Rückhalteeinrichtung angebracht sind. Zur Umlenkung der Transportriemen 101 weist, wie in Fig. 4 dargestellt, die Vereinzelungswalze 80 auf der Achse 82 freilaufende Umlaufräder 103 auf, über die die Transportriemen 101 umgelenkt werden. Bei Bedarf können solche freilaufenden Umlaufräder auch in der Rückhaltewalze 90 und im Gegenrad 93 vorgesehen werden.The sheet material 11 drawn off from the stack 10 can then be transported by a transport system for example transported to further processing facilities become. The transport system here has transport belts 100 and 101, between which the sheet material drawn off from the stack 10 is transported. The transport belts 100 are deflected here around planet wheels 102 which are mounted on axes 92 and 94 of the restraint. For Deflection of the transport belt 101 has, as shown in Fig. 4, the Separating roller 80 on idler gears 103 on axle 82, via which the conveyor belts 101 are deflected. If necessary, such idler gears also in the retaining roller 90 and in the counter wheel 93 are provided.

Optional kann im Eingabefach ein hier nicht dargestellter Sensor vorgesehen werden, der die Anwesenheit von Blattgut detektiert. Die von dem Sensor detektierten Meßwerte können beispielsweise zur Steuerung des Antriebs der Vereinzelungswalze 80 als auch zur Steuerung des Antriebs 60 verwendet werden.Optionally, a sensor, not shown here, can be provided in the input compartment be detected by the presence of leaf material. The one from the sensor Detected measured values can be used, for example, to control the drive the separating roller 80 and used to control the drive 60 become.
