Description

Die Erfindung betrifft eine Transportvorrichtung zur geordneten Annahme, Förderung und Übergabe einzelner Blätter und/oder Blattstapel, umfassend ein Unterteil mit einem ersten Rahmen und mit an diesem gelagerten zueinander parallelen ersten Transportrollen, über die mindestens ein in zwei Richtungen antreibbares erstes endloses Transportband gespannt ist, und ein Oberteil mit einem zweiten Rahmen und mit an diesem gelagerten, zueinander und zu den ersten Transportrollen parallelen zweiten Transportrollen, über die mindestens ein in zwei Richtungen antreibbares zweites endloses Transportband gespannt ist, wobei das Oberteil relativ zum Unterteil im Sinne einer Veränderung des gegenseitigen Abstandes der ersten und zweiten Transportbänder parallel zu sich selbst verstellbar ist.The invention relates to a transport device for ordered Acceptance, promotion and handover of individual leaves and / or sheet stack comprising a base with a first Frame and with this mounted parallel to each other first transport rollers, over which at least one in two directions drivable first endless conveyor belt is taut, and a top with a second frame and with each other, with each other and with the first Transport rollers parallel second transport rollers, over the at least one drivable in two directions second endless conveyor belt is stretched, wherein the upper part relative to the lower part in the sense of a change of the mutual Distance between the first and second conveyor belts is adjustable parallel to itself.

Eine solche Transportvorrichtung ist beispielsweise aus der WO 99/41712 A1 bekannt. Die dort beschriebene Transporteinrichtung dient beispielsweise dazu, Banknoten von einer Vielzahl von Banknotenbehältern zu einer Ausgabeöffnung eines Geldautomaten zu transportieren. Die Transportbänder von Oberteil und Unterteil bilden gemeinsam einen Transportspalt, um einzelne Banknoten oder auch Banknotenbündel fördern zu können. Dabei wird der Abstand zwischen den Transportbändern von Oberteil und Unterteil, d.h. die Dicke des Transportspaltes durch eine Verstellung des Oberteils relativ zum Unterteil eingestellt.Such a transport device is for example from the WO 99/41712 A1. The transport device described there serves, for example, to banknotes of one Variety of banknote containers to a dispensing opening of a ATMs to transport. The conveyor belts of upper part and lower part together form a transport gap, to individual banknotes or bundles of banknotes to be able to promote. The distance between the Conveyor belts from top and bottom, i. the fat the transport gap by an adjustment of the upper part adjusted relative to the lower part.

In der DE 2 131 258 A wird eine Transportvorrichtung für ein Medienbündel beschrieben, die aus einem unteren angetriebenen Zubringerband und einem darüber liegenden nicht angetriebenen angefederten Pressband besteht, welches keine Kraft in Transportrichtung auf das Medienbündel ausübt. Durch diese Anordnung wird das gewünschte Aufschuppen des Medienbündels unterstützt.In DE 2 131 258 A, a transport device for described a bundle of media driven from a lower Feeder belt and one not above it driven spring-loaded press belt, which no Force exerts in the transport direction on the media bundle. By this arrangement, the desired shed of the Supported media bundle.

In der JP 04 052 786 A wird eine Transportvorrichtung beschrieben, die ein Medienbündel zwischen zwei parallelen Transportriemen zu transportieren vermag, wobei das Medienbündel zwischen den Transportriemen dadurch eingeklemmt wird, dass der untere Teil der Transportvorrichtung in Richtung der oberen Transportriemen verschiebbar ist.JP 04 052 786 A describes a transport device, the one media bundle between two parallel Transport belt can transport, with the media bundle thereby trapped between the conveyor belt is that the lower part of the transport device in Direction of the upper conveyor belt is displaced.

Die US 4,670,081 A beschreibt ebenfalls eine Transportvorrichtung mit parallelen Transportriemen. Auch hier wird der Anpressdruck auf das Medienbündel dadurch erreicht, dass lediglich ein Teil der Transportvorrichtung, in diesem Falle der obere Teil der Vorrichtung, in Richtung der unteren Transportriemen verschiebbar ist.The US 4,670,081 A also describes a transport device with parallel conveyor belts. Again, the Contact pressure on the media bundle achieved by that only part of the transport device, in this case the upper part of the device, towards the lower one Transport belt is displaceable.

Bei solchen Anordnung tritt das Problem auf, dass die Transportbänder von Oberteil und Unterteil exakt gleich laufen müssen und sich unabhängig von der Dicke des Trans portgutes (Einzelblatt oder Blattstapel unterschiedlicher Höhe) sowie beim Öffnen und Schließen der Transporteinrichtung nicht gegeneinander verschieben dürfen. Bei einer Relativbewegung zwischen den Transportbändern würden die Blätter eines Blattstapels voneinander geschoben.In such an arrangement, the problem arises that the Conveyor belts from top and bottom exactly the same have to run and regardless of the thickness of the trans portgutes (single sheet or stack of sheets of different Height) and when opening and closing the transport device not allowed to move against each other. In a relative movement between the conveyor belts would the Leaves of a stack of leaves pushed one from the other.

Zur Lösung dieses Problems wird erfindungsgemäß vorgeschlagen, daß die ersten und die zweiten Transportrollen über ein Riemengetriebe durch denselben Motor antreibbar sind, der an einem der Rahmen befestigt ist. Damit ist ein exakter Gleichlauf der Transportbänder gewährleistet, ohne die Verstellbarkeit des Oberteils relativ zum Unterteil zu behindern. To solve this problem, the invention proposes that the first and the second transport rollers over a belt transmission can be driven by the same motor, which is attached to one of the frames. This is an exact one Synchronization of the conveyor belts ensured without the Adjustability of the upper part to hinder relative to the lower part.

Erfindungsgemäß hat das Riemengetriebe eine an dem Unterteil gelagerte, mit den ersten Transportrollen gekoppelte erste Treibrolle und eine an dem Oberteil gelagerte, mit den zweiten Transportrollen gekoppelte zweite Transportrolle, wobei die beiden Treibrollen an einander diagonal gegenüberliegenden Gelenkpunkten eines Gelenkparallelogramms angeordnet sind, an dessen beiden anderen Gelenkpunkten jeweils eine frei drehbare Rolle gelagert ist, und wobei die an den Gelenkpunkten angeordneten Rollen durch einen Treibriemen miteinander verbunden sind. Diese Konstruktion stellt sicher, daß beim Verändern des Abstandes zwischen Oberteil und Unterteil, d.h. zwischen den Transportbändern der Treibriemen stillsteht, d.h. die Treibrollen an Oberteil und Unterteil sich ebenfalls nicht bewegen. Zugleich ist der Umfang des von den Rollen an den Gelenkpunkten gebildeten Parallelogramms stets gleich, so daß der Treibriemen unabhängig von der Stellung des Oberteils relativ zum Unterteil einer gleichbleibenden Spannung ausgesetzt ist. According to the belt drive has one mounted on the base, with the first transport rollers coupled first drive roller and one at the top mounted, coupled to the second transport rollers second transport roller, wherein the two drive rollers at diagonally opposite hinge points of a Jointed parallelogram are arranged, at the other two Hinged each mounted a freely rotatable roller is, and being arranged at the hinge points Rolls are connected by a drive belt. This construction ensures that when changing the Distance between top and bottom, i. between the conveyor belts of the drive belts are stationary, i. the Drive rollers on top and bottom also not move. At the same time, the scope of the roles of the Hinge points formed parallelogram always the same, so that the drive belt regardless of the position of the upper part relative to the lower part of a constant tension is exposed.

Vorzugsweise sind die an den Gelenkpunkten angeordneten Rollen Zahnräder oder Zahnrollen, die mit dem als Zahnriemen ausgebildeten Treibriemen in Eingriff stehen.Preferably, they are arranged at the hinge points Rolling gears or sprockets with the toothed belt trained drive belt engaged.

Der Motor ist zweckmäßigerweise am Unterteil befestigt, so daß die Masse des verstellbaren Teiles gering gehalten wird. Die Koppelung zwischen dem Motor und der an dem Unterteil gelagerten Treibrolle kann in der Weise erfolgen, daß ein Ritzel auf der Ausgangwelle des Motors mit einer der ersten Transportrollen und einer zur ersten Treibrolle coaxialen Rolle über einen Zahnriemen gekoppelt ist. Die zweite Treibrolle ihrerseits ist mit einem Zahnrad gekoppelt, das mit einem mit einer der zweiten Transportrollen drehfest verbundenen Zahnrad kämmt.The engine is suitably attached to the lower part, so that kept the mass of the adjustable part low becomes. The coupling between the engine and the lower part stored drive roller can be done in the way that a pinion on the output shaft of the motor with a the first transport rollers and one to the first drive roller coaxial roller is coupled via a toothed belt. The second drive roller in turn is coupled with a gear, the one with one of the second transport rollers rotatably connected gear meshes.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Rahmen von Unterteil und Oberteil parallel zur Stellrichtung aneinandergeführt, wobei an dem Rahmen eines der Teile mindestens ein über einen Motor antreibbares Zahnrad gelagert ist, das mit einer an dem jeweils anderen Teil angeordneten Zahnstange in Eingriff steht. Auf diese Weise können die beiden Teile exakt relativ zueinander verstellt werden.In a preferred embodiment of the invention the frame of lower part and upper part parallel to the direction of adjustment led to each other, wherein on the frame of the one Parts at least one driven by a motor gear is mounted, arranged with one at the other part Rack is engaged. In this way The two parts can be adjusted exactly relative to each other become.

Die in den Figuren 1 und 2 dargestellte Transportvorrichtung umfaßt ein allgemein mit 10 bezeichnetes Unterteil und ein mit 12 bezeichnetes Oberteil. Das Unterteil 10 hat einen Rahmen 14 mit zwei zueinander parallelen Rahmenwänden 16, die durch Streben 18 (von denen nur eine in der Figur 1 zu erkennen ist) miteinander verbunden sind. Das Oberteil 12 hat einen Rahmen 20 mit zueinander parallelen Rahmenwänden 22, die durch Streben 24 miteinander verbunden sind, wobei die Länge der Streben 24 geringer als die Länge der Streben 18 ist, so daß der Rahmen 20 des Oberteils 12 zwischen die Rahmenwände 16 des Rahmens 14 paßt.The transport device shown in Figures 1 and 2 comprises a generally designated 10 lower part and a shell designated 12. The lower part 10 has a Frame 14 with two mutually parallel frame walls 16, by struts 18 (only one of which in the figure 1 can be seen) are interconnected. The top 12 has a frame 20 with mutually parallel frame walls 22, which are connected by struts 24, wherein the length of the struts 24 is less than the length of the Struts 18 is, so that the frame 20 of the upper part 12 between the frame walls 16 of the frame 14 fits.

Am oberen Rand der Rahmenwände 16 sind jeweils vertikale rechteckige Aussparungen 26 vorgesehen (Figur 2), deren eine vertikale Kante als Zahnstange 28 ausgebildet ist. Mit diesen Zahnstangen 28 kämmen Ritzel 30, die auf Wellen 32 sitzen, die sich parallel zu den Streben 24 quer durch den Rahmen 20 des Oberteils 12 erstrecken. Die Ritzel 30 werden gemeinsam von einem Motor 34 angetrieben, der an der in Figur 1 dem Betrachter zugewandten Rahmenwand 22 befestigt ist und über ein Untersetzungsgetriebe 36 ein Zahnrad 38 antreibt, das seinerseits über einen Zahnriemen 40 Zahnräder 42 antreibt, die drehfest auf den Wellen 32 sitzen. Dadurch ist das Oberteil 12 an dem Unterteil 10 in vertikaler Richtung verstellbar geführt.At the top of the frame walls 16 are each vertical rectangular recesses 26 provided (Figure 2), one of them vertical edge is designed as a rack 28. With These racks 28 mesh pinion 30, the waves on 32nd sitting parallel to the struts 24 across the Frame 20 of the upper part 12 extend. The pinions 30 are driven jointly by a motor 34, which at the in FIG 1 facing the viewer facing frame wall 22 attached is and a reduction gear 36, a gear 38th drives, in turn, via a toothed belt 40 gears 42 drives, the rotationally fixed on the shafts 32 sit. Thereby is the upper part 12 on the lower part 10 in vertical Direction adjustable guided.

Am vorderen und rückwärtigen Ende des Unterteils 10 ist zwischen den Rahmenwänden 16 jeweils eine erste Transportwalze oder Transportrolle 44 mit parallel zu den Streben 18 gerichteter Achse gelagert. Über die Transportwalzen 44 sind mehrere parallel zueinander verlaufende endlose erste Transportbänder oder Transportriemen 46 gespannt.At the front and rear end of the lower part 10 is between the frame walls 16 each have a first transport roller or transport roller 44 with parallel to the struts 18th directed axis stored. About the transport rollers 44 are a plurality of mutually parallel endless first Conveyor belts or transport belt 46 stretched.

In gleicher Weise ist am vorderen und rückwärtigen Ende des Oberteils 12 zwischen den Rahmenwänden 22 jeweils eine zweite Transportwalze oder -rolle 48 mit parallel zu den Streben 24 gerichteter Achse gelagert. Über die zweiten Transportwalzen 48 sind mehrere zweite endlose Transportbänder 50 gespannt. Die ersten Transportbänder 46 und die zweiten Transportbänder 50 bilden zusammen einen Transportspalt 52 zum Transport von Einzelblättern wie Banknoten oder dergleichen oder auch von Blattstapeln oder Banknotenbündeln, wobei der vertikale Abstand zwischen den ersten Transportbändern 46 und den zweiten Transportbändern 50 durch eine Höhenverstellung des Oberteils 12 relativ zum Unterteil 10 exakt eingestellt werden kann.In the same way is at the front and rear end of the Upper part 12 between the frame walls 22 each one second transport roller or roller 48 with parallel to the Struts 24 aligned axis stored. About the second Transport rollers 48 are a plurality of second endless conveyor belts 50 excited. The first conveyor belts 46 and the second conveyor belts 50 together form a transport gap 52 for transporting individual sheets such as banknotes or the like, or also of sheet stacks or banknote bundles, the vertical distance between the first Conveyor belts 46 and the second conveyor belts 50 by a height adjustment of the upper part 12 relative to Lower part 10 can be set exactly.

Der Antrieb der Transportwalzen 44 und 48 erfolgt von einem an einer Rahmenwand 16 des Unterteils 10 befestigten Motor 54 über eine Getriebeanordnung 56, die im folgenden näher erläutert werden soll.The drive of the transport rollers 44 and 48 is carried out by a on a frame wall 16 of the lower part 10 fixed motor 54 via a gear assembly 56, the closer in the following should be explained.

Ein auf der Ausgangswelle 58 des Motors 54 sitzendes Ritzel 60 ist über einen Zahnriemen 62 mit einem auf der Welle 64 der dem Motor 54 benachbarten Transportwalze 44 sitzenden Zahnrad 66 und einem Zahnrad 68 gekoppelt, das an der den Motor 54 tragenden Rahmenwand 16 um eine zur Achse der Transportwalze 44 parallele Achse frei drehbar gelagert ist. Auf der Welle 70 des Zahnrades 68 sitzt drehfest mit letzterem gekoppelt ein weiteres Zahnrad 72.A seated on the output shaft 58 of the motor 54 pinion 60 is via a toothed belt 62 with a on the shaft 64th the motor 54 adjacent transport roller 44 sitting Gear 66 and a gear 68 coupled to the the Motor 54 bearing frame wall 16 to one to the axis of the Transport roller 44 parallel axis freely rotatably mounted is. On the shaft 70 of the gear 68 is seated against rotation the latter coupled another gear 72nd

An der benachbarten Rahmenwand 22 des Rahmens 20 des Oberteiles 12 ist ein Zahnrad 74 um eine zu der Achse der zweiten Transportwalze 48 parallele Achse frei drehbar gelagert und steht in Eingriff mit einem Zahnrad 76, das auf der Welle 78 dieser zweiten Transportwalze 48 sitzt. Das Zahnrad 74 ist drehfest mit einem Zahnrad oder einer Zahnrolle 80 gekoppelt, das coaxial mit ihm auf der Welle 82 sitzt.On the adjacent frame wall 22 of the frame 20 of the upper part 12 is a gear 74 about one to the axis of the second Transport roller 48 parallel axis freely rotatably mounted and is engaged with a gear 76, which on the Shaft 78 of this second transport roller 48 is seated. The gear 74 is rotationally fixed with a gear or a toothed roller 80 coupled coaxially with it on the shaft 82 is seated.

Die beiden Wellen 70 und 82 bilden zwei einander diagonal gegenüberliegende Gelenkpunkte eines allgemein mit 84 bezeichneten Hebelparallelogramms oder Gelenkviereckes, durch das Oberteil 12 und Unterteil 10 mechanisch miteinander verbunden sind. In den beiden anderen Gelenkpunkten dieses Hebelparallelogramms 84 sind zwei weitere Zahnrollen 86 frei drehbar gelagert, die über einen Zahnriemen 88 mit dem Zahnrad 72 und dem Zahnrad 80 gekoppelt sind. Damit können die ersten Transportwalzen 44 und die zweiten Transportwalzen 48 synchron aber gegenläufig angetrieben werden.The two waves 70 and 82 form two diagonally opposite hinge points of a generally designated 84 Lever parallelogram or quadrilateral, by the upper part 12 and lower part 10 mechanically together are connected. In the other two hinge points this Hebelparallelogramms 84 are two other sprockets 86th freely rotatably mounted, which via a toothed belt 88 with the Gear 72 and the gear 80 are coupled. With that you can the first transport rollers 44 and the second transport rollers 48 synchronously but driven in opposite directions.

Man erkennt, daß bei einer Höhenverstellung des Oberteils 12 relativ zum Unterteil 10, wobei sich die von den Wellen 70 und 82 gebildeten Gelenkpunkte voneinander entfernen oder einander annähern, die Drehlage der Zahnräder 72 und 80 relativ zueinander unverändert bleibt. Ebenso ändert sich der Parallelogrammumfang bei dieser Verstellung nicht, so daß auch die Spannung des Zahnriemens 88 bei dieser Verstellung unverändert bleibt. Damit wird ein absoluter Gleichlauf der Transportbänder 46 des Unterteils mit den Transportbändern 50 des Oberteils sichergestellt und zwar unabhängig von der Stellung des Oberteils 12 relativ zum Unterteil 10.It can be seen that at a height adjustment of the upper part 12 relative to the lower part 10, wherein the waves 70 and 82 formed hinge points from each other or approach each other, the rotational position of the gears 72 and 80 remains unchanged relative to each other. Likewise changes the parallelogram circumference does not vary with this adjustment, so that the tension of the belt 88 at this adjustment remains unchanged. This will be an absolute Synchronization of the conveyor belts 46 of the lower part with the Secured conveyor belts 50 of the upper part and that regardless of the position of the upper part 12 relative to Lower part 10.
