Der Automat 1 umfasst weiter einen Sensor 5 sowie ein mit ihm verbundenes Steuergerät 6, ein Zuführsystem 7, ein Transportsystem 8 mit zwei Ausgängen, wobei der eine in eine Kassette 9 und der andere Ausgang in eine Rückgabeschale 10 münden. Das Zuführsystem 7 und das Transportsystem 8 bilden den Zwischenspeicher. Das Beförderungssystem 4 ist zum Transport der Blätter 2 vom Annahmeschlitz 3 des Automaten 1 am Sensor 5 vorbei zu einem Eingang 11 des Zuführsystems 7 eingerichtet.In Figure 1, 1 means a service machine (short Automat 1) and 2 a sheet that through a slot 3 of the Vending machine 1 is pushed into a transport system 4. The Automat 1 further comprises a sensor 5 and one with it connected control device 6, a feed system 7, a transport system 8 with two outputs, one in a cassette 9 and the other exit into a return tray 10. The Feed system 7 and transport system 8 form the intermediate store. The transport system 4 is for transporting the Leaves 2 from the acceptance slot 3 of the machine 1 on the sensor 5 over to an entrance 11 of the feed system 7.

Das Steuergerät 6 erzeugt Befehle an den Zwischenspeicher, wobei die Befehle einem Annahmezyklus oder einem Transportzyklus zugeordnet sind. Der Annahmezyklus umfasst zwei Ruhezustände und Annahmevorgänge bzw. Leerfahrten. Der Zwischenspeicher gelangt von dem einen Ruhezustand in den andern mittels des Annahmevorgangs bzw. der Leerfahrt. Während des Annahmezyklus wartet der Zwischenspeicher im Ruhezustand, bis das ihm während des Annahmevorgangs mittels des Beförderungssystems 4 zugeführte Blatt 2 den Eingang 11 erreicht. Sobald der Annahmezyklus beendet ist, wechselt das Steuergerät 6 in den Transportzyklus, wobei die während des Annahmezyklus im Zwischenspeicher gesammelten Blätter 2 durch einen der beiden Ausgänge in die Kassette 9 bzw. in die Rückgabeschale 10 transportiert werden. The control unit 6 generates commands to the buffer, whereby the commands of an acceptance cycle or a transport cycle assigned. The acceptance cycle comprises two idle states and Acceptance processes or empty runs. The cache arrives from one idle state to the other by means of the acceptance process or the empty run. Waits during the acceptance cycle the buffer in the idle state until it is during the Acceptance process supplied by the transport system 4 Sheet 2 reached entrance 11. Once the acceptance cycle has ended, the control unit 6 changes to the transport cycle, where the during the acceptance cycle in the buffer collected leaves 2 through one of the two exits into the Cassette 9 or transported into the return tray 10.

Das Beförderungssystem 4 transportiert das Blatt 2 durch den Eingang 11 in das Zuführsystem 7, das Blatt um Blatt auf einem sich bildenden Stapel 12 im Transportsystem 8 ablegt, wobei der Stapel 12 beim Aufschichten des neu zugeführten Blatts 2 nicht bewegt wird.One after the other, sheets 2 can be conveyed through the transport system 4 Acceptance slot 3 are fed until the acceptance cycle ends is. The transport system 4 transports the sheet 2 through the entrance 11 into the feed system 7, sheet by sheet deposits a stack 12 that is being formed in the transport system 8, the stack 12 when stacking the newly fed Sheet 2 is not moved.

Sind z. B. die Blätter 2 Banknoten, kann der Automat 1 einen vorbestimmten Betrag für eine Dienstleistung verlangen und nimmt solange Banknoten entgegen, bis das Steuergerät 6 mittels des Sensors 5 festgestellt hat, dass der vorgegebene Betrag erreicht ist. Der Benutzer kann auch dem Automaten 1 über eine an der Frontseite des Automaten 1 angeordnete, mit dem Steuergerät 6 verbundene Tastatur 13 den einzugebenden Betrag übermitteln oder das Ende des Annahmezyklus anzeigen.Are z. B. the sheets 2 banknotes, the machine 1 can one demand and takes predetermined amount for a service as long as banknotes until the control unit 6 by means of Sensor 5 has determined that the predetermined amount has been reached is. The user can also use the machine 1 via a Front of the machine 1 arranged with the control unit 6 connected keyboard 13 transmit the amount to be entered or indicate the end of the acceptance cycle.

Das Steuergerät 6 ist mit einem Speicher 14 verbunden, der für jedes Blatt 2 im Stapel 12 die Prüfergebnisse, wie z. B. die Wertigkeit, die Echtheit usw., zwischenspeichert. Ist der Annahmevorgang beendet, überprüft das Steuergerät 6 den Inhalt des Speichers 14, ob alle Blätter 2 im Stapel 12 den vorbestimmten Anforderungen genügen. Trifft dies zu, entscheidet das Steuergerät 6, den Stapel 12 zu kassieren, wobei die Transporteinrichtung 8 den Stapel 12 in die Kassette 9 befördert, wenn nicht, wird der Stapel 12 zurückgewiesen und der Rückgabeschale 10 übergeben. Das Steuergerät 6 kann den Annahmezyklus auch sofort abbrechen und den Stapel 12 in die Rückgabeschale 10 befördern lassen, wenn das Steuergerät 6 das Blatt 2 als ein den Anforderungen nicht genügendes klassifiziert hat oder der Benutzer über die Tastatur 13 den Annahmezyklus beendet.The control device 6 is connected to a memory 14, which for each sheet 2 in the stack 12 the test results, such as. B. the Value, authenticity, etc., cached. Is the The acceptance process ends, the control unit 6 checks the content of memory 14, whether all sheets 2 in the stack 12 den meet predetermined requirements. If this is the case, decide the control unit 6 to collect the stack 12, the Transport device 8 the stack 12 in the cassette 9th if not, the stack 12 is rejected and the Hand over the return tray 10. The control unit 6 can Abort the acceptance cycle immediately and put the stack 12 in the return tray 10 conveyed when the control unit 6 sheet 2 classified as not satisfying the requirements or the user via the keyboard 13 the acceptance cycle completed.

Die Figur 2 zeigt beispielhaft einen Zwischenspeicher. Als Zeichenebene ist eine der parallelen Schnittebenen 15 durch den im Ruhezustand befindlichen Zwischenspeicher gewählt. Das Zuführsystem 7 (Figur 1) ist von einem Endlosband 16 und von einem Zuführband 17 gebildet, während das Transportsystem 8 (Figur 1) das Endlosband 16 und ein endloses Transportband 18 umfasst. Gestrichelt gezeichnete Führungen und Strecken des Endlosbands 16 liegen ausserhalb der Schnittebene 15, um einen Blattransport nicht zu behindern. Das Endlosband 16 und das Zuführband 17 sind oberhalb einer zur Schnittebene 15 senkrechten Stapelebene 19, 19' angeordnet, während sich das Transportband 18 unterhalb dieser befindet.Figure 2 shows an example of a buffer. As Drawing plane is one of the parallel section planes 15 through the Intermediate memory selected in the idle state. The Feed system 7 (Figure 1) is of an endless belt 16 and a feed belt 17 is formed, while the transport system 8 (Figure 1) the endless belt 16 and an endless conveyor belt 18th includes. Guided tours and routes of the Endless belts 16 lie outside the cutting plane 15 by one Do not hinder sheet transport. The endless belt 16 and that Feed belt 17 are above one to the cutting plane 15 vertical stacking level 19, 19 'arranged while the Conveyor belt 18 is located below this.

Wenigstens in der Stapelebene 19, 19' sind Teile der beiden Bänder 16 und 18 parallel geführt und schliessen die Stapelebene 19, 19' ein. Zwischen Stapelstrecken des Endlosbands 16, die die Stapelebene 19, 19' festlegen, und einer dazu parallelen näheren Teilstrecke des Transportbandes 18 ist der Stapel 12 eingeklemmt, wobei der Stapel 12 die Teilstrecke des Transportbands 18 von der Stapelebene 19, 19' wegdrückt. Das zu Beginn des Annahmevorgangs auf den Stapel 12 abgelegte Blatt 2 liegt direkt auf dem Transportband 18 auf.At least in the stacking plane 19, 19 'are parts of the two Bands 16 and 18 run parallel and close the stacking level 19, 19 'a. Between stacking sections of the endless belt 16, which define the stacking level 19, 19 ', and one parallel to it The closer section of the conveyor belt 18 is the stack 12 pinched, the stack 12 the section of the conveyor belt 18 pushes away from the stacking level 19, 19 '. That at the beginning of the acceptance process on sheet 12 deposited sheet 2 directly on the conveyor belt 18.

Das endlose Transportband 18 ist von einer Antriebswalze 20 und einer Laufwalze 21 aufgespannt, so dass die eine Teilstrecke des Transportbands 18 und die Stapelstrecke des Endlosbandes 16 einen zur Stapelebene 19, 19' parallelen Transportweg des Stapels 12 bilden, der durch die beiden Walzen 20 und 21 begrenzt ist. Der Transportweg des Stapels 12 mündet auf der einen Seite in die Kassette 9 und auf der anderen Seite in die Rückgabeschale 10. The endless conveyor belt 18 is from a drive roller 20 and a roller 21 spanned, so that a section of the Conveyor belt 18 and the stacking section of the endless belt 16 a parallel to the stacking level 19, 19 'transport path of the Form stack 12 by the two rollers 20 and 21st is limited. The transport path of the stack 12 opens onto the one side in the cassette 9 and on the other side in the Return tray 10.

Es ist von Vorteil, wenn wenigstens im Bereich des Stapels 12 weitere Stützwalzen 22, 22' angeordnet sind, die den Stapel 12 und das Transportband 18 auf der parallelen Strecke unterstützen und den Stapel 12 stabilisieren. Die Achsen der Walzen 20 bis 22 sind zueinander parallel und in einem Rahmen 23 angeordnet.It is advantageous if at least in the area of the stack 12 further support rollers 22, 22 ′ are arranged, which stack 12 and support the conveyor belt 18 on the parallel route and stabilize the stack 12. The axes of the rollers 20 to 22 are parallel to each other and arranged in a frame 23.

Der Rahmen 23 ist senkrecht zur Stapelebene 19, 19' unter Ueberwindung einer Gegenkraft verschiebbar, die z. B. von Federn erzeugt wird, so dass vorteilhaft eine grosse Anzahl Blätter 2 auf den Stapel 12 geschichtet werden können und der Zwischenspeicher eine grosse Speicherkapazität aufweist, die nur von der Ausbildung des Rahmens 23 bzw. seinem Federweg abhängt. Die Gegenkraft presst den Stapel 12 zusammen und stellt sicher, dass er im Transportweg des Stapels 12 zwischen dem Endlosband 16 und dem Transportband 18 sicher gehalten ist.The frame 23 is perpendicular to the stack plane 19, 19 'below Overcoming a counterforce displaceable, the z. B. of feathers is generated, so that advantageously a large number of sheets 2 can be stacked on the stack 12 and the buffer has a large storage capacity that only from the Formation of the frame 23 or its travel depends. The Counterforce compresses the stack 12 and ensures that he in the transport path of the stack 12 between the endless belt 16 and the conveyor belt 18 is held securely.

Die Antriebswalze 20 weist einen Walzenmotor 24 auf, der über eine Leitung mit dem Steuergerät 6 verbunden und von ihm gespeist ist. Der Walzenmotor 24 kann auf dem Rahmen 23 angeordnet sein. Das Steuergerät 6 kann den Walzenmotor 24 bzw. das Transportband 18 in einer vorbestimmten Laufrichtung antreiben. Während des Annahmezyklus blockiert der Walzenmotor 24 das Transportband 18.The drive roller 20 has a roller motor 24, which a line connected to the control unit 6 and from it is fed. The roller motor 24 can be on the frame 23 be arranged. The control unit 6 can the roller motor 24 or the conveyor belt 18 in a predetermined direction drive. The roller motor locks during the acceptance cycle 24 the conveyor belt 18.

Parallel zur Stapelebene 19, 19' und zur Schnittebene 15 ist auf der Seite des Endlosbands 16 eine Schiene 25 für einen auf ihr zwischen zwei Endstellungen 26 und 27 verschiebbaren Wagen 28 angeordnet. Die Endstellungen 26 und 27 liegen ausserhalb des Bereichs des Stapels 12, wobei die erste Endstellung 26 näher bei der Rückgabeschale 10 ist. Der Wagen 28 trägt in der Schnittebene 15 nebeneinander drei Führungsrollen 29 bis 31. Die beiden äusseren Führungsrollen 29 und 31 berühren mit ihrem Umfang einerseits die Stapelebene 19, 19' sowie andererseits eine dazu parallele Zuführebene 32, die beide die Schnittebene 15 schneiden. Die erste äussere Führungsrolle 29 ist näher bei der Rückgabeschale 10 als die zweite Führungsrolle 31.Parallel to the stacking level 19, 19 'and the cutting level 15 is on the side of the endless belt 16 a rail 25 for one on it between two end positions 26 and 27 movable carriage 28th arranged. The end positions 26 and 27 are outside the Area of the stack 12, the first end position 26 closer is 10 in the return tray. The carriage 28 carries in the Section plane 15 side by side three guide rollers 29 to 31. Die both outer guide rollers 29 and 31 touch with their Scope on the one hand the stacking level 19, 19 'and on the other hand a parallel feed plane 32, both the cutting plane 15 cut. The first outer guide roller 29 is closer in the return tray 10 as the second guide roller 31.

Von der Rückgabeschale 10 her gesehen, erstreckt sich das Endlosband 16 in der Stapelebene 19, 19' zwischen einer Laufrolle 33 und der ersten äusseren Führungsrolle 29 sowie zwischen der zweiten äusseren Führungsrolle 31 und einer Antriebsrolle 34 und bilden die beiden Stapelstrecken des Endlosbands 16. Die Laufrolle 33 und die Antriebsrolle 34 sind so distanziert, dass sich dazwischen die Schiene 25 mit den beiden Endstellungen 26, 27 erstreckt. Oberhalb der Stapelebene 19, 19' ist das Endlosband 16 mittels Umlenkrollen 35, 36 ausserhalb der Schnittebenen 15 von der Antriebsrolle 34 zur Laufrolle 33 geführt.Seen from the return tray 10, this extends Endless belt 16 in the stacking level 19, 19 'between a roller 33 and the first outer guide roller 29 and between the second outer guide roller 31 and a drive roller 34 and form the two stacking sections of the endless belt 16. Die Roller 33 and drive roller 34 are spaced so that in between the rail 25 with the two end positions 26, 27 extends. The endless belt is above the stacking level 19, 19 ' 16 by means of deflection rollers 35, 36 outside the cutting planes 15 out of the drive roller 34 to the roller 33.

Beispielsweise sind über dem Stapel 12 und oberhalb der Zuführebene 32 im gleichen Abstand eine erste Eingangsrolle 37 und eine zweite Eingangsrolle 38 angeordnet, wobei sich die erste Eingangsrolle 37 in der Schnittebene 15 näher zur Rückgabeschale 10 befindet. Etwas weiter von der Zuführebene 32 entfernt ist zwischen den beiden Eingangsrollen 37 und 38 eine Weichenrolle 39 gelagert.For example, are above the stack 12 and above the feed level 32 a first input roller 37 and a second input roller 38 is arranged, the first Input roller 37 in the sectional plane 15 closer to the return tray 10 is located. A little further away from the feed level 32 is a switch roller between the two input rollers 37 and 38 39 stored.

Die erste äussere Führungsrolle 29 hebt das Endlosband 16 von der Stapelebene 19, 19' ab und lenkt es in der Schnittebene 15 um 180° in die Zuführebene 32 ab. Von der ersten äusseren Führungsrolle 29 bis zur ersten Eingangsrolle 37 berührt das Endlosband 16 das Zuführband 17 und bildet so auf dieser Strecke einen ersten Förderweg 40 für das Blatt 2. Die erste Eingangsrolle 37 trennt die beiden Bänder 16 und 17. Das Endlosband 16 ist mittels weiterer Umlenkrollen 41, 42 ausserhalb der Schnittebenen 15 zur zweiten Eingangsrolle 38 geführt. Das Zuführband 17 ist zur Weichenrolle 39, um 180° um diese zur Zuführebene 32 umgelenkt und liegt bei der zweiten Eingangsrolle 38 wieder auf dem Endlosband 16 auf. Gemeinsam sind die beiden Bänder 16, 17 bis zur zweiten äusseren Führungsrolle 31 geführt und bilden einen zweiten Förderweg 43 für das Blatt 2. In den Schnittebenen 15 lenkt die zweite äussere Führungsrolle 31 das Endlosband 16 aus der Zuführebene 32 um 180° in die Stapelebene 19, 19' ab. Die Länge der beiden Förderwege 40 und 43 hängt von der Stellung des Wagens 28 auf der Schiene 25 ab.The first outer guide roller 29 lifts the endless belt 16 off the stacking plane 19, 19 'and steers it in the cutting plane 15 180 ° into the feed level 32. From the first exterior Guide roller 29 touches the first input roller 37 Endless belt 16 forms the feed belt 17 and thus forms on this route a first feed path 40 for the sheet 2. The first input roll 37 separates the two belts 16 and 17. The endless belt 16 is outside of the cutting planes by means of further deflection rollers 41, 42 15 led to the second input roller 38. The feed belt 17 is to switch roller 39, 180 ° around this to the feed level 32 deflected and lies with the second input roller 38 again on the endless belt 16. The two are together Bands 16, 17 out to the second outer guide roller 31 and form a second conveyor path 43 for the sheet 2. In the Cutting planes 15 guides the second outer guide roller 31 Endless belt 16 from the feed plane 32 through 180 ° into the stacking plane 19, 19 '. The length of the two conveying paths 40 and 43 depends on the position of the carriage 28 on the rail 25.

Die mittlere Führungsrolle 30 drückt zwischen den beiden äusseren Führungsrollen 29 und 31 das Zuführband 17 bis auf einen vorbestimmten kleinen Abstand auf die Stapelebene 19, 19' hinab, während das Zuführband 17 auf dem um die äusseren Führungsrollen 29 und 31 geschlungenen Endlosband 16 aufliegt. Ein am Wagen 28 unterhalb der mittleren Führungsrolle 30 befestigtes Ablenkblech 28' verhindert einen Kontakt des Zuführbandes 17 mit dem Stapel 12.The middle guide roller 30 presses between the two outer guide rollers 29 and 31, the feed belt 17 to a predetermined small distance to the stacking level 19, 19 ' down while the feed belt 17 is on the around the outer Guide rollers 29 and 31 looped endless belt 16 rests. One on the carriage 28 below the middle guide roller 30 attached baffle 28 'prevents contact of the feed belt 17 with the stack 12.

Die beiden Förderwege 40 und 43 können zum Platzsparen mit wechselnder Transportrichtung in der Schnittebene 15 mittels wenigstens einer Ablenkwalze 44 und mittels wenigstens einer Ablenkrolle 45 geführt sein, über die die Bänder 16 und 17 gemeinsam aus der Zuführebene 32 bis zu den Eingangsrollen 37 und 38 laufen.The two conveying paths 40 and 43 can be used to save space changing transport direction in the sectional plane 15 by means of at least one deflecting roller 44 and by means of at least one Deflection roller 45 can be guided over the belts 16 and 17th together from the feed plane 32 to the input rollers 37 and 38 run.

Die Rollen und Walzen sind frei um ihre Achsen drehbare, den Bändern 16 bis 18 angepasste Zylinder. Die Achsen der Walzen 20 bis 22, der Führungsrollen 29 bis 31, der Eingangsrollen 37 und 38, der Weichenrolle 39 sowie der Ablenkwalze 44 und der Ablenkrolle 45 sind senkrecht zu den Schnittebenen 15 angeordnet. Die vom Wagen 28 getragenen Achsen der Führungsrollen 29 bis 31 sind parallel zu den obenerwähnten, fest angeordneten Achsen verschiebbar. Die Achsen der Laufrolle 33, Antriebsrolle 34 und der Umlenkrollen 35, 36, 41 und 42 können gegen die Schnittebene 15 geneigt sein, wie dies die Führung des Endlosbandes 16 ausserhalb der Schnittebenen 15 bedingt.The rollers and rollers are freely rotatable about their axes Bands 16 to 18 customized cylinders. The axes of the rollers 20 to 22, the guide rollers 29 to 31, the input rollers 37 and 38, the switch roller 39 and the deflection roller 44 and the Deflection roller 45 are perpendicular to the cutting planes 15 arranged. The axles of the guide rollers carried by the carriage 28 29 to 31 are fixed in parallel with the above arranged axes can be moved. The axes of the roller 33, Drive roller 34 and the deflection rollers 35, 36, 41 and 42 can be inclined against the cutting plane 15, as is the leadership of the Endless belt 16 outside the cutting planes 15 conditionally.

Die Antriebsrolle 34 weist einen Antrieb 46 auf, der über eine Leitung mit dem Steuergerät 6 verbunden und von ihm gespeist ist. Das Steuergerät 6 kann den Antrieb 46 bzw. das Endlosband 16 in einer vorbestimmten Laufrichtung antreiben.
