Description

Vereinzelungseinrichtung mit einstellbarem Vereinzelungs- spaltSeparating device with adjustable separating gap
Die Erfindung betrifft eine Vereinzelungseinrichtung zum Einzelabzug von Wertscheinen, insbesondere Banknoten von einem in einem Magazin angeordneten Blattstapel mit zur Anlage an der Stirnfläche des Blattεtapels bestimmten antreibbaren Abzugsrollen, in Abzugsrichtung antreibbaren Transportrollen und entgegengesetzt zu diesen antreibba- ren Rückhalterollen, die mit den Transportrollen einen parallel zu einem Rand der Stapelstirnflache verlaufenden Vereinzelungsspalt bilden, wobei die Abzugs-, Transport- und Rückhalterollen jeweils auf zueinander parallelen Wellen in einem Rahmen so gelagert sind, daß die Breite des Vereinzelungsspaltes zwischen den Transportrollen und den Rückhalterollen einstellbar ist.The invention relates to a separating device for the individual removal of notes of value, in particular banknotes from a stack of sheets arranged in a magazine with drive rollers which are drivable for abutment against the end face of the stack of sheets, transport rollers which can be driven in the pulling direction and opposite to these drivable retaining rollers which run parallel to the transport rollers form a separating gap extending to an edge of the stack end face, the take-off, transport and retaining rollers each being mounted on mutually parallel shafts in a frame such that the width of the separating gap between the transport rollers and the retaining rollers is adjustable.
Vereinzelungseinrichtungen der vorstehend genannten Art mit Friktionsvereinzelung der Wertscheine, insbesondere Banknoten, erzeugen die Trennwirkung in dem Vereinze- lungsspalt, der durch größere Transportrollen und kleinere, langsam entgegengesetzt laufende Rückhaitrollen gebildet wird. Die Trennwirkung hängt stark von der Spaltgröße ab und wird aber auch durch Eigenschaften der abzuziehenden Scheine, beispielsweise die Papierqualität von Banknoten oder ihren Gebrauchszustand beieinflußt. Der Vereinzelungsspalt muß beispielsweise für dünnere Scheine oder bei schlechten Separiereigenschaften wie starker Reibung oder Verkleben der Scheine untereinander enger eingestellt werden, um die Zahl der Doppelabzüge oder Mehrfachabzüge in zulässigen Grenzen zu halten. Gleiches gilt auch für einen Verschleiß der Rückhalterollen. Wird der Vereinzelungsspalt jedoch zu eng eingestellt, werden die abzuziehenden Scheine gestaucht und/oder beschädigt und es kann zum Stau kommen. Eine ungünstige Spalteinstellung wirkt sich nicht immer sofort aus, sie kann sich auch erst bei einer größeren Zahl von Vereinzelungen oder bei einer Schwankung der Scheinqualität zeigen.Separation devices of the type mentioned above with friction separation of the banknotes, in particular banknotes, produce the separating effect in the separation gap, which is formed by larger transport rolls and smaller, slowly counter-rotating return rolls. The separating effect depends strongly on the gap size and is also influenced by the properties of the notes to be removed, for example the paper quality of banknotes or their condition of use. The separation gap, for example, for thinner notes or in the case of poor separation properties such as strong friction or sticking of the notes to one another, must be set more narrowly in order to keep the number of double prints or multiple prints within permissible limits. The same applies to wear on the retaining rollers. However, if the separation gap is set too narrow, the notes to be removed are compressed and / or damaged and traffic jams can occur. An unfavorable gap setting does not always have an immediate effect, it can only become apparent when there are a large number of separations or when the apparent quality fluctuates.
Bei den heutigen Vereinzelungseinrichtungen der eingangs genannten Art, wie sie beispielsweise in Geldausgabeautomaten verwendet werden, wird zunächst eine Standardeinstellung vorgegeben, die am Einsatzort manuell durch den Kundendienst oder auch durch den Bediener korrigiert wird. Da in einem Geldautomaten die Banknotenmagazine relativ häufig nachgeladen werden müssen und insbesondere der Gebrauchszuεtand der Banknoten stark schwankt, muß der Vereinzelungsspalt der Vereinzelungseinrichtung häufig eingestellt werden, wobei es von der Erfahrung der betreffenden Bedienungsperson abhängt, wie rasch der richtige Einstellwert gefunden wird. In der Regel sind auch einige Probeabzüge erforderlich, um die richtige Einstellung zu finden.With today's separating devices of the type mentioned at the outset, as are used, for example, in automated teller machines, a standard setting is first specified, which is corrected manually by the customer service or by the operator at the place of use. Since the banknote magazines have to be reloaded relatively frequently in an automated teller machine and, in particular, the state of use of the banknotes fluctuates greatly, the separating gap of the separating device has to be set frequently, it depending on the experience of the operator concerned how quickly the correct setting value can be found. Usually, a few proofs are required to find the right setting.
Der Erfindung liegt die Aufgabe zugrunde, eine Vereinze- lungseinrichtung der eingangs genannten Art so auszubilden, daß ein zuverlässiger Einzelabzug gewährleistet werden kann, ohne daß ständig der Kundendienst zur Einstellung der Vereinzelungseinrichtung bemüht werden muß.The invention is based on the object of designing a separating device of the type mentioned at the outset in such a way that a reliable individual deduction can be ensured without the customer service department having to constantly strive to adjust the separating device.
Zur Lösung dieser Aufgabe hat die erfindungsgemäße Ver- einzelungseinrichtung eine Einrichtung zum Erfassen von Abzugsfehlern, eine durch einen Stellantrieb antreibbare Stelleinrichtung zum Einstellen der Breite des Vereinzelungsspaltes und eine programmierbare Steuereinrichtung zum Steuern des Stellantriebes in Abhängigkeit der Art oder Häufigkeit der erfaßten Abzugsfehler.To achieve this object, the individualization device according to the invention has a device for detecting withdrawal errors, an actuating device which can be driven by an actuator to adjust the width of the separating gap and a programmable control device for controlling the actuator depending on the type or frequency of the detected withdrawal errors.
Die erfindungsgemäße Lösung ermöglicht also eine Selbst- nachstellung des Vereinzelungsspaltes, wobei fehlerhafte Einstellungen durch mangelnde Erfahrung des Serviceperso- nals vermieden werden können, indem die Steuervorrichtung auf im Labor ermittelte optimale und in der Steuervorrichtung gespeicherte Einstellwerte zurückgreifen kann.The solution according to the invention thus enables the separating gap to be readjusted itself, incorrect settings being caused by inexperience of the service person. nals can be avoided in that the control device can fall back on optimal setting values determined in the laboratory and stored in the control device.
Eine Möglichkeit zum Erfassen von Abzugsfehlern besteht darin, daß die Vereinzelungseinrichtung Mittel zum Erfassen der Anzahl von Mehrfachabzügen pro Zeiteinheit umfaßt. Wird beispielsweise die Doppelabzugsrate, d.h. die Anzahl von Doppelabzügen pro Zeiteinheit zu hoch, muß der Vereinzelungsspalt enger gestellt werden. Dabei kann der gemessenen Anzahl von Doppelabzügen ein Nachstellwert zugeordnet werden, der als Differenzwert gegenüber einer Grundeinstellung oder als Absolutwert ausgegeben wird. Die Zuordnung zwischen Doppelabzugsrate und Nachstellwert stellt unter Berücksichtigung der Banknotensorte und der Banknotenqualität einen Erfahrungswert dar. Diese Werte sind vorzugsweise in dem Programm der Steuereinrichtung in Tabellen abgelegt. Über die Stelleinrichtung wird dann der Vereinzelungsspalt entsprechend dem vorgegebenen Nachstellwert enger gestellt.One possibility for detecting deduction errors is that the separating device comprises means for detecting the number of multiple deductions per unit of time. For example, if the double deduction rate, i.e. the number of double deductions per unit of time too high, the separation gap must be narrowed. An adjustment value can be assigned to the measured number of double deductions, which is output as a difference value compared to a basic setting or as an absolute value. The assignment between the double deduction rate and the readjustment value represents an empirical value, taking into account the banknote type and the banknote quality. These values are preferably stored in tables in the program of the control device. The separating gap is then narrowed via the adjusting device in accordance with the predetermined readjustment value.
Abzugsfehler, die von einem zu engen Vereinzelungsspalt herrühren, können beispielsweise dadurch erfaßt werden, daß eine Zeitmeßeinrichtung zum Messen der Zeitspanne vorgesehen ist, die zwischen der Abgabe eines Abzugs- signals und der Ausführung des Blattabzugs vergeht. Ab- zugsprobleme, die auf einem zu engen Vereinzelungsspalt beruhen, kündigen sich in den meisten Fällen durch eine Abzugszeitverzögerung an. Die Abzugszeit kann dabei beispielsweise vom Bestromen der Abzugskupplung (AbzugsSignal) bis zum Erkennen der Banknotenvorderkante durch einen Sensor stromabwärts des Vereinzelungsspaltes definiert werden. Der Mittelwert aus mehreren Abzügen muß hierbei unter einem vorgegebenen Grenzwert bleiben. Wird dieser Grenzwert überschritten, wird der Spalt breiter gemacht . Bei einem zu engen Spalt können abhängig von der Blattsteifigkeit und der Oberflächenbeschaffenheit der Blätter diese ausknicken, stauchen und den Vereinzelungε- spalt blockieren. Bei gebrauchten Banknoten in schlechtem Zustand wird dieser Fall früher eintreten als bei neuen Banknoten, die noch glatt und steif sind.Discharge errors which result from an excessively narrow separation gap can be detected, for example, by providing a time measuring device for measuring the period of time that elapses between the emission of a trigger signal and the execution of the sheet trigger. Deduction problems that are based on a narrow separation gap usually result in a delay time. The withdrawal time can be defined, for example, by energizing the withdrawal clutch (withdrawal signal) to recognizing the front edge of the banknotes by a sensor downstream of the separating gap. The average of several deductions must remain below a specified limit. If this limit is exceeded, the gap is made wider. If the gap is too narrow, depending on the Leaf stiffness and the surface quality of the leaves buckle them, compress them and block the separating gap. This situation will occur earlier with used banknotes in poor condition than with new banknotes that are still smooth and stiff.
Die Einstellung des Vereinzelungsspaltes kann in der Weise erfolgen, daß die die Rückhalterollen tragende Welle radial zu der die Transportrollen tragenden Welle verstellbar in dem Rahmen gelagert und über Verbindungsarme mit einem Exzentertrieb verbunden ist, wobei der Stellantrieb einen mit dem Exzentertrieb über ein Getriebe gekoppelten Schrittmotor umfaßt .The setting of the separating gap can be carried out in such a way that the shaft carrying the retaining rollers is mounted in the frame in an adjustable manner radially to the shaft carrying the transport rollers and is connected via connecting arms to an eccentric drive, the actuator comprising a stepper motor coupled to the eccentric drive via a gear .

Die Banknoten 12 stehen hochkant auf einem Magazinboden 14 und werden über einen Stempel 16 unter dem Druck einer Feder 18 gegen eine nicht dargestellte Frontwand des Magazins gedrückt.A magazine 10 for receiving a stack of banknotes 12 is shown in FIG. The banknotes 12 stand upright on a magazine base 14 and are pressed against a front wall of the magazine, not shown, by means of a stamp 16 under the pressure of a spring 18.
Mit dem Magazin 10 verbunden ist eine allgemein mit 20 bezeichnete Vereinzelungseinrichtung, die in bekannterConnected to the magazine 10 is a separating device, generally designated 20, which is known in the art
Weise dazu dient, das jeweils vorderste Blatt bzw. die jeweils vorderste Banknote 22 von dem Stapel 12 im dargestellten Fall nach unten einzeln abzuziehen.Way serves the front sheet or the to remove the foremost banknote 22 from the stack 12 individually in the illustrated case.
Die Vereinzelungseinrichtung 20 umfaßt einen Rahmen mit Rahmenseitenteilen 24 (Figur 2) , die durch nicht darge- stellte Querstreben miteinander verbunden sind. In den Rahmenseitenteilen 24 sind auf einer Welle 26 Abzugsrol- len 28 so gelagert, daß sie durch die nicht dargestellte Stirnwand des Magazins 10 hindurch an der Stirnfläche des Banknotenstapels 12, d.h. an dem jeweils vordersten abzu- ziehenden Blatt 22 anliegen. Die Abzugsrollen 28 sind in Richtung des Pfeiles 30 antreibbar, so daß sie das jeweils vorderste Blatt 22 nach unten durch eine dort vorgesehene Öffnung im Magazin 10 ausschieben können. Nahe dieser Öffnung unterhalb der Abzugsrollen 28 sind mittels einer Welle 32 Transportrollen 34 drehbar in den Rahmenseitenteilen 24 gelagert. Den Transportrollen 34 sind Rückhalterollen 36 zugeordnet, die mittels einer Welle 38 in den Rahmenseitenteilen 24 gelagert sind. Die Welle 38 liegt dabei mit ihren Enden in in den Rahmenseitenteilen 24 ausgebildeten Schlitzen 40, die so gerichtet sind, daß die parallel zu der Welle 32 der Transportrollen 34 gerichtete Welle 38 der Rückhalterollen 40 radial zur Welle 32 verstellt werden kann. Die Transportrollen 34 und die Rückhalterollen 38 bilden zusammen einen mit der Ebene der jeweils vordersten Banknote 22 fluchtenden Vereinzelungsspalt 42, dessen Breite durch die Verstellung der Welle 38 in den Schlitzen 40 verändert werden kann. Die Transportrollen 34 und die Rückhalterollen 36 werden über gemeinsam an beiden anliegende Antriebsrollen 44 in Rich- tung der in Figur 1 eingezeichneten Pfeile 46 angetrieben.The separating device 20 comprises a frame with frame side parts 24 (FIG. 2) which are connected to one another by cross struts (not shown). In the frame side parts 24, take-off rollers 28 are mounted on a shaft 26 such that they pass through the end wall of the magazine 10, not shown, on the end face of the stack of banknotes 12, i.e. rest against the foremost sheet 22 to be removed. The take-off rollers 28 can be driven in the direction of the arrow 30, so that they can push out the foremost sheet 22 downward through an opening provided in the magazine 10. Near this opening below the take-off rollers 28, transport rollers 34 are rotatably mounted in the frame side parts 24 by means of a shaft 32. The transport rollers 34 are assigned retaining rollers 36 which are mounted in the frame side parts 24 by means of a shaft 38. The ends of the shaft 38 lie in slots 40 formed in the frame side parts 24, which are directed in such a way that the shaft 38 of the retaining rollers 40 directed parallel to the shaft 32 of the transport rollers 34 can be adjusted radially to the shaft 32. The transport rollers 34 and the retaining rollers 38 together form a separating gap 42 that is aligned with the plane of the foremost bank note 22, the width of which can be changed by adjusting the shaft 38 in the slots 40. The transport rollers 34 and the retaining rollers 36 are driven by means of drive rollers 44 which are in common in the direction of the arrows 46 shown in FIG. 1.
An den Vereinzelungsspalt 42 schließt sich stromabwärts desselben eine die Transportrollen 34 koaxial umgebene Umlenkführung 48 an, die an einem Riemenförderer 50 en- det, der in Verbindung mit einem stationären Leitblech 52 die abgezogenen Banknoten nach oben in Richtung des Pfeiles 54 ihrer weiteren Verwertung zuführt . Der Riemenförderer 50 kann in an sich bekannter Weise mehrere Endlos- riemen 56 umfassen, die jeweils obere und untere Umlenkrollen 58 umschlingen, die ihrerseits mit Wellen 60 in den Rahmenseitenteilen 24 drehbar gelagert sind.Downstream of the separating gap 42 is a deflection guide 48, which coaxially surrounds the transport rollers 34 and which is attached to a belt conveyor 50. det, which in conjunction with a stationary guide plate 52 feeds the withdrawn banknotes upwards in the direction of arrow 54 for their further use. The belt conveyor 50 can comprise, in a manner known per se, a plurality of endless belts 56, each of which wraps around the upper and lower deflection rollers 58, which in turn are rotatably mounted with shafts 60 in the frame side parts 24.
Erfindungsgemäß ist der Vereinzelungsspalt 42 zwischen den Transportrollen 34 und den Rückhalterollen 36 in Ab- hängigkeit bestimmter Kriterien automatisch einstellbar. Hierzu sind die Enden der Welle 38 der Rückhalterollen 36 über parallel zu den Rahmenseitenteilen 24 außerhalb derselben verlaufende Verbindungs rme 64 mit einer Stelleinrichtung 66 verbunden. Die Stelleinrichtung umfaßt eine Stellwelle 68, die in den Rahmenseitenteilen 24 drehbar gelagert ist. Drehfest mit der Stellwelle 68 ist ein Schneckenzahnrad 70 verbunden, das in Eingriff mit einer Schneckenwelle 72 steht. Diese wird über einen Schrittmotor 74 angetrieben, der an einem rechtwinkelig umgeboge- nen Seitenflansch 76 des in Figur 2 rechten Rahmenseitenteils 24 angeordnet ist. Auf den Enden der Stellwelle 68 sind die Verbindungsarme 64 über drehfest mit der Stell- welle 68 verbundene Exzenterbuchsen 78 drehbar gelagert.According to the invention, the separating gap 42 between the transport rollers 34 and the retaining rollers 36 can be set automatically as a function of certain criteria. For this purpose, the ends of the shaft 38 of the retaining rollers 36 are connected to an actuating device 66 via connecting arms 64 running parallel to the frame side parts 24 outside the same. The actuating device comprises an actuating shaft 68 which is rotatably mounted in the frame side parts 24. A worm gear 70, which is in engagement with a worm shaft 72, is connected in a rotationally fixed manner to the actuating shaft 68. This is driven by a stepper motor 74 which is arranged on a side flange 76 which is bent at right angles to the frame side part 24 on the right in FIG. The connecting arms 64 are rotatably supported on the ends of the adjusting shaft 68 by means of eccentric bushings 78 which are non-rotatably connected to the adjusting shaft 68.
Wird die Exzenterwelle 68 über den Schrittmotor 74 und den Schneckentrieb 72, 70 verdreht, so bewirken die Exzenterbuchsen 78 eine Verschiebung der Verbindungsarme 64 in ihrer Längsrichtung und damit eine Verstellung der Welle 38 der Rückhalterollen 36 radial zur Welle 32 der Transportrollen 34. Der Vereinzelungsspalt 42 ist somit über den beschriebenen Stellmechanismus in seiner Breite einstellbar.If the eccentric shaft 68 is rotated via the stepper motor 74 and the worm drive 72, 70, the eccentric bushings 78 cause the connecting arms 64 to be displaced in their longitudinal direction and thus to adjust the shaft 38 of the retaining rollers 36 radially to the shaft 32 of the transport rollers 34. The separating gap 42 is thus adjustable in width using the adjusting mechanism described.
Der Schrittmotor 74 ist mit einer programmierbaren Steuervorrichtung 80 verbunden und wird von dieser angesteuert. Die Steuervorrichtung 80 ist ferner mit einer ström- abwärts der Vereinzelungseinrichtung 20 im Transportweg der abgezogenen Banknoten angeordneten Vorrichtung 82 zum Erkennen von Doppel- und Mehrfachabzügen verbunden. Solche Vorrichtungen sind an sich bekannt und werden hier nicht näher erläutert . Ferner ist die Steuervorrichtung 80 mit einem stromabwärts des Vereinzelungsspaltes 42 im Transportweg der abgezogenen Banknoten abgeordneten Sensor 84 verbunden, der auf die Vorderkante einer abgezogenen Banknote anspricht. Ein solcher Sensor kann bei- spielsweise eine Lichtschranke sein.The stepper motor 74 is connected to a programmable control device 80 and is controlled by it. The control device 80 is also equipped with a flow Downstream of the separating device 20 in the transport path of the withdrawn banknotes arranged device 82 for detecting double and multiple deductions. Such devices are known per se and are not explained in more detail here. Furthermore, the control device 80 is connected to a sensor 84, which is arranged downstream of the singling gap 42 in the transport path of the withdrawn banknotes and which responds to the front edge of a withdrawn banknote. Such a sensor can be a light barrier, for example.
Die Steuereinrichtung erhält einerseits von der Einrichtung 82 die Information, ob Doppel- und Mehrfachabzüge von Banknoten erfolgen. Überschreitet die Anzahl von Doppelabzügen in einem gegebenen Zeitraum einen bestimmten Wert, so ist dies ein Indiz, daß der Vereinzelungsspalt 42 zu breit ist. In diesem Falle greift das Programm in der Steuervorrichtung 80 auf eine abgespeicherte Tabelle zurück, in der für eine gegebene Banknotensorte und ggf. auch für einen bestimmten Erhaltungszustand Erfahrungs- werte für eine Nachstellung des Vereinzelungsspaltes 42 abgespeichert sind. Entsprechend dem so ermittelten Nachstellwert aktiviert die Steuervorrichtung 80 den Schrittmotor 74, der über eine Drehung der Stellwelle 68 den Vereinzelungsspalt 42 schmaler macht. Diese Prozedur wird ggf. wiederholt, falls die Doppelabzugsrate nicht unter den vorgegebenen Grenzwert f llt .On the one hand, the control device receives information from the device 82 as to whether double and multiple withdrawals of banknotes take place. If the number of double deductions exceeds a certain value in a given period of time, this is an indication that the separating gap 42 is too wide. In this case, the program in the control device 80 uses a stored table in which empirical values for a readjustment of the separating gap 42 are stored for a given type of banknote and possibly also for a certain state of preservation. In accordance with the readjustment value determined in this way, the control device 80 activates the stepping motor 74, which makes the separating gap 42 narrower by rotating the actuating shaft 68. This procedure may be repeated if the double deduction rate does not fall below the specified limit.
Andererseits kann die Steuervorrichtung 80 aufgrund eines von dem Sensor 84 erhaltenen Signales feststellen, ob die Vorderkante einer abgezogenen Banknote 22 in einer gege- benen Zeitspanne nach Aktivieren der Abzugsrollen 28 oder nach Abgabe eines Abzugssignales eine bestimmte Strecke zurückgelegt hat. Wird dieser vorgegebene Zeitwert überschritten, ist dies ein Indiz dafür, daß der Vereinze- lungsspalt 42 zu eng ist. Dann steuert die Steuervorrich- tung 80 den Schrittmotor 74 in der Weise an, daß der Spalt 42 breiter gemacht wird. Wird über den Sensor 84 festgestellt, daß überhaupt keine Banknote durch den Vereinzelungsspalt 42 gelangt ist, daß also möglicherweise ein Stau vor dem Vereinzelungsspalt 42 aufgetreten ist, so kann der Spalt 42 über die Steuereinrichtung 80 und die Stelleinrichtung soweit geöffnet werden, daß die zurückgehaltene Banknote oder die aufgestauten Banknoten insgesamt in jedem Falle durch den Vereinzelungsspalt hindurchtreten können und somit der Stau beseitigt wird. Anschließend kann der Spalt wieder auf die gewünschte Breite eingestellt werden.On the other hand, the control device 80 can determine on the basis of a signal received from the sensor 84 whether the leading edge of a withdrawn banknote 22 has covered a certain distance in a given period of time after the trigger rollers 28 have been activated or after a trigger signal has been given. If this predetermined time value is exceeded, this is an indication that the separation gap 42 is too narrow. Then the control device controls device 80 the stepper motor 74 in such a way that the gap 42 is made wider. If it is determined via the sensor 84 that no banknote has ever passed through the separating gap 42, that is to say that a jam may have occurred in front of the separating gap 42, the gap 42 can be opened via the control device 80 and the actuating device to such an extent that the retained banknote or the pent-up banknotes can pass through the separating gap in any case and the jam is thus eliminated. The gap can then be adjusted to the desired width.
Die vorstehende Beschreibung zeigt, daß die erfindungsgemäße Lösung ein automatisches Einstellen der Breite des Vereinzelungsspaltes ermöglicht, wodurch die Verfügungszeit eines mit der erfindungsgemäßen Vereinzelungseinrichtung ausgerüsteten Geldausgabeautomaten und die Wartungsintervalle erheblich verlängert werden können. The above description shows that the solution according to the invention enables the width of the separating gap to be set automatically, as a result of which the availability of a cash dispenser equipped with the separating device according to the invention and the maintenance intervals can be considerably extended.
