Abstract

A device to feed web material in sections to a treatment station is described, in which in each case one of several webs (4), transported in guide channels located above one another and converging in a fan shape towards the treatment station, are optionally advanced by means of a controllable drive device, the front section of this web is separated from the latter after treatment and the end of the web, which is the front end after separation, is withdrawn from the treatment station. For this purpose, the controllable drive device can optionally be brought into engagement with one web in each case in the region of the assigned guide channel for the complete forward and return transport of this web before and after a treatment operation. The drive device preferably has reversibly drivable cylinders (9) and, to produce an engagement between a web and at least one cylinder, guide elements (7, 8) forming the guide channels are preferably swivellable in relation to the cylinders. A printing device, in which, for example, tickets differing by their colour are to be printed, serves expediently as the treatment station. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung nach dem Ober­begriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Aus der EP 0 048 329 B1 ist eine Druckmaschine mit einem Eingangswalzenpaar zum Fördern einer stückweise zu bedruckenden Druckmaterialbahn, einer Druckvor­richtung und einer Abschneidevorrichtung für das bedruckte Bahnstück bekannt. Diese Druckmaschine soll in der Weise ausgebildet sein, daß mit ihr auf eine wählbare von mehreren Druckmaterialbahnen gedruckt werden kann, wobei diese Bahnen beispielsweise ver­schieden breit, verschieden farbig oder mit verschie­denen Vordrucken versehen sein können. Zu diesem Zweck sind mehrere flache Führungskanäle für je eine von mehreren Druckmaterialbahnen fächerförmig angeordnet und auf die der Druckvorrichtung abgewandte Seite des Klemmspaltes des Walzenpaares gerichtet, wobei jeweils jedem Führungskanal eine einzeln antreibbare Fördervorrichtung zugeordnet ist. Diese ist so ausge­ staltet, daß sie vor einem Druckvorgang die zu bedruckende der je in einen der Kanäle hineinragenden Druckmaterialbahnen längs des Kanals vorschiebt und sie nach dem Einlaufen des freien Bahnendes in den Walzenspalt des rotierenden Walzenpaares losläßt, das dann die Bahn weiter in Druckposition vorschiebt und nach dem Abschneidevorgang zurückschiebt. Bevor das beim Abschneiden gebildete Bahnende den Walzen­spalt verläßt, wird die Bahn von der Fördervorrichtung wieder erfaßt und um eine Strecke zurückgeschoben, die gleich der Vorschubstrecke der Fördervorrichtung längs des Kanals ist.EP 0 048 329 B1 discloses a printing press with a pair of input rollers for conveying a web of printing material to be printed piece by piece, a printing device and a cutting device for the printed web section. This printing press should be designed in such a way that it can be used to print on a selectable one of a plurality of printing material webs, these webs being able, for example, to have different widths, different colors or different forms. For this purpose, a plurality of flat guide channels for each of a plurality of printing material webs are arranged in a fan shape and directed towards the side of the clamping nip of the pair of rollers facing away from the printing device, with each guide channel being assigned an individually drivable conveying device. This is so out stalt that before a printing process that the printing material webs that protrude into one of the channels advances along the channel and releases them after the free web end has entered the nip of the rotating roller pair, which then advances the web into the printing position and after the cutting process pushes back. Before the web end formed during the cutting leaves the nip, the web is again grasped by the conveyor device and pushed back by a distance which is equal to the feed distance of the conveyor device along the channel.

Diese bekannte Druckmaschine ist relativ aufwendig, da sie für den Vor- und Rückschub jeder Bahn zwei in ihrer Steuerung aufeinander abgestimmte Transportmittel, d.h. die Fördervorrichtung und das Walzenpaar, benötigt.This known printing press is relatively complex since it has two means of transport which are coordinated with one another in terms of their control for the advancement and retraction of each web, i. the conveyor and the pair of rollers needed.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur abschnittsweisen Zuführung von bahnförmigem Gut zu einer Bearbeitungsstation, bei der mittels einer steuerbaren Antriebsvorrichtung wahlweise jeweils eine von mehreren in übereinanderliegenden, fächerförmig zur Bearbeitungsstation zusammenlaufenden Führungskanälen transportierten Bahnen vorgeschoben, der vordere Abschnitt dieser Bahn nach der Bearbeitung von dieser abgetrennt und das nach dem Abtrennen vordere Ende der Bahn aus der Bearbeitungsstation zurückgezogen werden, zu schaffen, die konstruktiv einfacher ausge­bildet ist als die bekannte Druckmaschine und daher sowohl hinsichtlich der Herstellung als auch hinsicht­lich des Betriebs einschließlich der Wartung und der Störanfälligkeit vorteilhafter ist. Diese Aufgabe wird erfindungsgemäß durch das im kennzeichnenden Teil des Anspruchs 1 angegebene Merkmal gelöst. Vorteilhafte Weiterbildungen der erfindungsgemäßen Vorrichtung ergeben sich aus den Unteransprüchen.It is therefore the object of the present invention to provide a device for the section-wise feeding of web-like material to a processing station, in which, by means of a controllable drive device, one of several tracks transported in superimposed, fan-shaped guide channels leading to the processing station is advanced, the front section of this track the processing of this separated and the front end of the web after the separation are withdrawn from the processing station to create, which is structurally simpler than the known printing press and therefore more advantageous in terms of both manufacture and operation, including maintenance and susceptibility to failure is. This object is achieved by the feature specified in the characterizing part of claim 1. Beneficial Further developments of the device according to the invention result from the subclaims.

Da die steuerbare Antriebsvorrichtung wahlweise mit jeweils einer Bahn im Bereich des zugeordneten Führungskanals in Eingriff bringbar ist für den voll­ständigen Vor- und Rücktransport dieser Bahn vor und nach einem Bearbeitungsvorgang, entfällt das antreib­bare Walzenpaar zwischen den Führungskanälen und der Bearbeitungsstation.Since the controllable drive device can optionally be brought into engagement with one track in the area of the assigned guide channel for the complete forward and return transport of this track before and after a processing operation, the drivable pair of rollers between the guide channels and the processing station is eliminated.

Die Antriebsvorrichtung weist vorzugsweise umkehrbar antreibbare Walzen auf, die mit jeweils einer der in den Führungskanälen befindlichen Bahnen in Eingriff bringbar sind, wobei zweckmäßig zur Herstellung eines Eingriffs zwischen einer Bahn und mindestens einer Walze der Antriebsvorrichtung die Führungskanäle bildende Leitelemente gegenüber den Walzen verschwenk­bar sind. Dies hat den Vorteil, daß die Walzen stationär gelagert sein können und zur Herstellung des Eingriffs, d.h. zum Transport einer Bahn, nur eine geringfügige Schwenkung der Leitelemente er­forderlich ist.The drive device preferably has reversibly drivable rollers which can be brought into engagement with one of the webs located in the guide channels, expediently to produce an engagement between a web and at least one roller of the drive device, guide elements forming the guide channels can be pivoted relative to the rollers. This has the advantage that the rollers can be stationary and for the production of the engagement, i.e. to transport a train, only a slight swivel of the guide elements is required.

Eine besonders einfache Ausbildung der Vorrichtung erhält man dadurch, daß jeder Walzezwei auf gegenüber­liegenden Seiten von dieser verlaufende Führungskanäle zugeordnet sind, wobei die einer Walze zugeordneten Führungskanäle durch ein gemeinsames Betätigungselement verschwenkbar sind. Zur gemeinsamen Verschwenkbarkeit der Leitelemente eines Führungskanals sind diese vor­zugsweise federnd miteinander gekoppelt.A particularly simple design of the device is obtained in that each roller is assigned two guide channels running on opposite sides thereof, the guide channels assigned to a roller being pivotable by a common actuating element. For the joint pivoting of the guide elements of a guide channel, these are preferably coupled to one another in a resilient manner.

Die Erfindung wird im folgenden anhand eines in den Figuren dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

  • Fig. 1 eine vereinfachte Darstellung der Seitenansicht einer ersten Ausführungs­form der Vorrichtung in Verbindung mit einer Druckvorrichtung,
  • Fig. 2 einen vergrößerten Ausschnitt aus Fig. 1,
  • Fig. 3 eine vereinfachte Darstellung der Seiten­ansicht einer zweiten Ausführungsform der Vorrichtung in Verbindung mit einer Druckvorrichtung, und
  • Fig. 4 einen Schnitt durch eine Transportwalze und zwei Gegendruckrollen entlang Linie IV-IV in Fig. 3.
The invention is explained in more detail below with reference to an exemplary embodiment shown in the figures explained. Show it:
  • 1 is a simplified representation of the side view of a first embodiment of the device in connection with a printing device,
  • 2 shows an enlarged detail from FIG. 1,
  • Fig. 3 is a simplified representation of the side view of a second embodiment of the device in connection with a printing device, and
  • 4 shows a section through a transport roller and two counter pressure rollers along line IV-IV in FIG. 3.

Einer Druckvorrichtung herkömmlicher Bauart wird gemäß Fig. 1 in den Spalt zwischen Druckkopf 1 und Druckbalken 2 von rechts zu bedruckendes bahnförmiges Papier zugeführt. Die gezeigte Vorrichtung ist für die Zuführung von vier verschiedenen Papier­bahnen geeignet, wobei jedoch stets nur eine ausge­wählte dieser vier Papierbahnen bis zur Druckvor­richtung vorgeschoben und deren vorderer Abschnitt in dieser bedruckt wird. Anschließend wird diese Papierbahn noch weiter vorgeschoben, bis sich der bedruckte Abschnitt links von einer vertikal bewegbaren Schneidklinge 3 befindet, die diesen Abschnitt von der Papierbahn abtrennt. Diese Papierbahn wird dann aus dem Bereich der Druckvorrichtung zurückge­zogen, bis ihr vorderes Ende sich im gleichen Abstand von der Druckvorrichtung befindet wie die vorderen Enden der anderen Papierbahnen.1, sheet-like paper to be printed from the right is fed into the gap between print head 1 and print bar 2. The device shown is suitable for feeding four different paper webs, but only a selected one of these four paper webs is always advanced to the printing device and the front section of which is printed on. This paper web is then advanced further until the printed section is to the left of a vertically movable cutting blade 3 which separates this section from the paper web. This paper web is then withdrawn from the area of the printing device until its front end is at the same distance from the printing device as the front ends of the other paper webs.

In dieser Stellung verharrt die Vorrichtung, bis erneut eine Papierbahn zum Bedrucken ausgewählt und in der vorbeschriebenen Weise bearbeitet wird. Die gezeigte Anordnung dient beispielsweise zur Herstellung von sich durch ihre Farbe unter­scheidenden Fahrkarten oder dergleichen.The device remains in this position until a paper web is again selected for printing and processed in the manner described above. The arrangement shown is used, for example, to produce tickets or the like that differ in their color.

Die Papierbahnen 4 werden zum Beispiel von Rollen abgezogen und zwischen Querstangen 5 hindurch­geführt, zwischen denen in ihrer Längsrichtung verschiebbare Reiter 6 zur seitlichen Führung der Papierbahnen gehalten sind. Jede Papierbahn 4 wird in einen aus zwei Leitblechen 7 und 8 ge­bildeten Führungskanal geleitet, wobei jeweils das Leitblech 7 benachbart zu einer Transport­rolle 9 und das Leitblech 8 auf der der zuge­ordneten Transportwalze 9 abgewandten Seite des Führungskanals liegen. Sämtliche Leitbleche 7 und 8 sind um ihr zur Druckvorrichtung weisendes Ende schwenkbar gelagert. Die Transportwalzen 9 sind durch Schrittmotoren umkehrbar antreibbar.The paper webs 4 are drawn off from rolls, for example, and passed between cross bars 5, between which tabs 6 which are displaceable in their longitudinal direction are held for lateral guidance of the paper webs. Each paper web 4 is guided into a guide channel formed from two guide plates 7 and 8, the guide plate 7 each lying adjacent to a transport roller 9 and the guide plate 8 lying on the side of the guide channel facing away from the associated transport roller 9. All baffles 7 and 8 are pivoted about their end facing the printing device. The transport rollers 9 are reversibly driven by stepper motors.

Wie aus Fig. 2 ersichtlich ist, enthält das Leitblech 7 eine Öffnung 10, durch die, wenn das Leitblech 7 gegen die Transportwalze 9 geschwenkt wird, diese hindurchtritt. Das Verschwenken der Leit­bleche 7 erfolgt mittels gabelförmiger Wippen 11, die drehfest auf steuerbaren Schwenkachsen 12 angeordnet sind. Jeder der beiden Schenkel einer Wippe 11 kann mit einem der Leitbleche 7 in Eingriff gebracht werden, wobei durch die Dreh­richtung der Wippe 1 bestimmt werden kann, welches der beiden zugeordneten Leitbleche 7 gegen die Transportwalze 9 geschwenkt wird.As can be seen from FIG. 2, the guide plate 7 contains an opening 10 through which, when the guide plate 7 is pivoted against the transport roller 9, it passes through. The guide plates 7 are pivoted by means of fork-shaped rockers 11, which are arranged in a rotationally fixed manner on controllable pivot axes 12. Each of the two legs of a rocker 11 can be brought into engagement with one of the guide plates 7, it being possible to determine which of the two associated guide plates 7 is pivoted against the transport roller 9 by the direction of rotation of the rocker 1.

Die Leitbleche 7 und 8 sind über eine Feder 13 miteinander gekoppelt. Die Feder 13 wird von einem durch das Leitblech 7 hindurchgreifenden und durch das Leitblech 8 gehaltenen Boden 14 getragen und ist zwischen dessen dem Leitblech 8 entgegengesetzten Ende und dem Leitblech 7 gespannt, so daß sie dieses gegen das Leitblech 8 drückt. Der Mindestabstand zwischen den Leitblechen 7 und 8 wird durch aus dem Leitblech 7 heraustretende sickenförmige Erhebungen 15 sichergestellt, die im Durchlaufbereich der Papierbahn 4 liegen.The guide plates 7 and 8 are coupled to one another via a spring 13. The spring 13 is supported by a bottom 14 which extends through the guide plate 7 and is held by the guide plate 8 and is stretched between its end opposite the guide plate 8 and the guide plate 7 so that it presses it against the guide plate 8. The minimum distance between the guide plates 7 and 8 is ensured by bead-like elevations 15 emerging from the guide plate 7, which lie in the passage area of the paper web 4.

Wird durch eine Wippe 11 ein Leitblech 7 gegen die zugeordnete Transportwalze 9 geschwenkt, so folgt durch Wirkung der Feder 13 das Leitblech 8 dieser Schwenkbewegung. Aufgrund der Öffnung 10 tritt die Transportwalze 9 durch das Leitblech 7 hindurch und gelangt in Kontakt mit dem Leitblech 8 bzw. der zwischen den Leitblechen befindlichen Papierbahn 4. Bei weiterem Verschwenken des Leit­blechs 7 wird das Leitblech 8 festgehalten, so daß die Erhebungen 15 sich von diesem lösen und einen Spalt für den Durchlauf der von der Transportwalze 9 angetriebenen Papierbahn 4 freigeben.If a guide plate 7 is pivoted against the assigned transport roller 9 by a rocker 11, the guide plate 8 follows this pivoting movement due to the action of the spring 13. Because of the opening 10, the transport roller 9 passes through the guide plate 7 and comes into contact with the guide plate 8 or the paper web 4 located between the guide plates. When the guide plate 7 is pivoted further, the guide plate 8 is held so that the elevations 15 move away loosen this and release a gap for the passage of the paper web 4 driven by the transport roller 9.

Die mittleren Führungskanäle sind so konzipiert, daß jeweils zwei benachbarte Führungskanäle ein gemeinsames Leitblech 8 besitzen. Die gezeigte Vorrichtung enthält vier Führungskanäle. Deren Anzahl kann jedoch ohne Schwierigkeiten erhöht werden, wobei für zwei Führungskanäle jeweils eine Transportwalze 9 und eine Wippe 11 vorgesehen sind.The middle guide channels are designed so that two adjacent guide channels each have a common guide plate 8. The device shown contains four guide channels. However, the number of these can be increased without difficulty, a transport roller 9 and a rocker 11 being provided for each of the two guide channels.

Ein allen Führungskanälen gemeinsames Leitblech 16 sorgt dafür, daß die jeweils vorgeschobene Papierbahn 4 der Druckvorrichtung einwandfrei zugeführt wird. Eine Abtastvorrichtung in Form einer Licht­schranke 17 erfaßt das vordere Ende einer vorge­schobenen Papierbahn 4, wodurch es möglich ist, Steuersignale für den weiteren genauen Vor- und Rücktransport dieser Papierbahn zu erzeugen.A guide plate 16 common to all guide channels ensures that the respectively advanced paper web 4 the printing device is fed properly. A scanning device in the form of a light barrier 17 detects the front end of an advanced paper web 4, which makes it possible to generate control signals for the further precise forward and return transport of this paper web.

Die Funktion der gezeigten Vorrichtung ist wie folgt: Es werden zunächst alle Papierbahnen 4 in die zugeordneten Führungskanäle vorgeschoben, bis ihre vorderen Enden jeweils an die als Anschläge dienenden Erhebungen 15 stoßen. Ein Weiterschieben ist nicht möglich, da die Erhebungen 15 durch die Federn 13 fest gegen die Leitbleche 8 gedrückt werden.The function of the device shown is as follows: First, all paper webs 4 are advanced into the associated guide channels until their front ends each abut the elevations 15 serving as stops. Moving on is not possible since the elevations 15 are pressed firmly against the guide plates 8 by the springs 13.

Soll nun der vordere Abschnitt einer Papierbahn 4 bedruckt und abgetrennt werden, werden durch ein entsprechendes Steuersignal die zugeordnete Transportwalze 9 mit der richtigen Drehrichtung angetrieben und die zugeordnete Wippe 11 über die Schwenkachse 12 so verschwenkt, daß der die ausgewählte Papierbahn 4 enthaltende Führungs­kanal zu der Transportwalze 9 hin bewegt wird. Diese tritt durch die Öffnung 10 im Leitblech 7 und drückt die Papierbahn 4 gegen das Leitblech 8. Gleichzeitig lösen sich die Erhebungen 15 vom Leitblech 8, so daß die Papierbahn 4 durch die sich drehende Transportwalze 9 vorgeschoben werden kann. Ihre Vorderkante wird von der Licht­schranke 17 erfaßt, so daß eine lagegenaue Steuerung der weiteren Bewegungen der Papierbahn 4 erfolgen kann. Diese wird nun in der Druckvor­richtung positioniert und nach Durchführu ng des Druckvorgangs wird der bedruckte Abschnitt über die Schneidklinge 3 vorgeschoben und dann abgetrennt. Um die Druckvorrichtung für die nächste zu be­druckende Papierbahn 4 frei zu machen, wird das vordere Ende der gerade bedruckten Papier­bahn 4 nach dem Abtrennen des bedruckten Abschnitts in ihren Führungskanal zurückge­zogen, indem die Drehrichtung der Transport­walze 9 umgekehrt wird. Dieses Zurückziehen erfolgt bis zu einer definierten Stelle im Führungskanal, die zwischen dem der Druckvor­richtung zugewandten Ende und den Erhebungen liegt. Nach Stillsetzung der Transportwalze 9 wird die Wippe 11 in ihre mittlere Stellung gebracht, so daß der Eingriff der Transport­walze 9 in den Führungskanal aufgehoben wird und die Papierbahn 4 durch die Erhebungen 15 festgeklemmt wird, so daß sie nicht unabsichtlich verschoben werden kann. Die Vorrichtung ist dann bereit für die Zuführung der nächsten Papier­bahn 4 zu der Druckvorrichtung.If the front section of a paper web 4 is now to be printed and separated, the associated transport roller 9 is driven with the correct direction of rotation by a corresponding control signal and the assigned rocker 11 is pivoted about the pivot axis 12 such that the guide channel containing the selected paper web 4 is guided to the transport roller 9 is moved. This passes through the opening 10 in the guide plate 7 and presses the paper web 4 against the guide plate 8. At the same time, the elevations 15 detach from the guide plate 8, so that the paper web 4 can be advanced by the rotating transport roller 9. Its front edge is detected by the light barrier 17 so that the further movements of the paper web 4 can be controlled in a precise position. This is now positioned in the printing device and after the printing process has been carried out, the printed section is placed over the Cutting blade 3 advanced and then severed. In order to clear the printing device for the next paper web 4 to be printed, the front end of the paper web 4 which has just been printed is withdrawn into its guide channel after the printed section has been severed, by reversing the direction of rotation of the transport roller 9. This retraction takes place up to a defined point in the guide channel, which lies between the end facing the printing device and the elevations. After the transport roller 9 has been stopped, the rocker 11 is brought into its central position, so that the engagement of the transport roller 9 in the guide channel is canceled and the paper web 4 is clamped by the elevations 15, so that it cannot be moved unintentionally. The device is then ready for feeding the next paper web 4 to the printing device.

Die anhand von Fig. 1 beschriebene Vorrichtung kann auch in der Weise ausgebildet sein, daß die Führungskanäle für das bahnförmige Gut nicht nur fächerförmig übereinander, sondern getrennt verwendbare Führungskanäle auch nebeneinander angeordnet sind. Dies bedingt eine entsprechend angepaßte Ausbildung der Bearbeitungsstation sowie der weiteren mit den Führungskanälen zusammenwirkenden Elemente der Zuführvorrichtung für das bahnförmige Gut.The device described with reference to FIG. 1 can also be designed in such a way that the guide channels for the web-shaped material are not only arranged one above the other in a fan shape but also separately usable guide channels. This requires a correspondingly adapted design of the processing station and of the further elements of the feed device for the web-like material which interact with the guide channels.

Fig. 3 zeigt ebenfalls eine bekannte Druckvor­richtung mit Druckkopf 1, Druckbalken 2 und Schneidklinge 3. Es sind vier übereinanderliegende Führungskanäle für die Zuführung jeweils einer Papierbahn 4 zu der Druckvorrichtung darge­stellt. Jeder Führungskanal wird durch ein oberes Leitblech 18 sowie ein unteres Leitblech 19 gebildet, zwischen denen die Papierbahn 4 gehalten ist. Jedes Paar von Leitblechen 18,19 ist gemeinsam um einen an ihrem der Druckvor­richtung zugewandten Ende gelegenen Drehpunkt schwenkbar. Zwischen jeweils zwei benachbarten Führungskanälen ist eine drehbare Transport­walze 20 fest gelagert. Die angrenzenden Leit­bleche, d.h. das untere Leitblech 19 des darüber­liegenden Führungskanals und das obere Leit­blech 18 des darunterliegenden Führungskanals, weisen Öffnungen 21 dergestalt auf, daß die Transportwalze 20 bei entsprechender Ver­schwenkung der Leitbleche 18, 19 durch sie hindurchtreten und mit der Papierbahn 4 in reibschlüssi­gen Kontakt gelangen kann.Fig. 3 also shows a known printing device with print head 1, pressure bar 2 and cutting blade 3. There are four superimposed Guide channels for feeding a paper web 4 to the printing device are shown. Each guide channel is formed by an upper guide plate 18 and a lower guide plate 19, between which the paper web 4 is held. Each pair of guide plates 18, 19 can be pivoted together about a pivot point located at their end facing the printing device. A rotatable transport roller 20 is fixedly mounted between each two adjacent guide channels. The adjacent guide plates, ie the lower guide plate 19 of the guide channel above and the upper guide plate 18 of the guide channel underneath, have openings 21 in such a way that the transport roller 20 passes through them when the guide plates 18, 19 are pivoted accordingly and makes frictional contact with the paper web 4 can reach.

Auf der gegenüberliegenden Seite jedes Führungs­kanals liegt der zugeordneten Transportwalze 20 jeweils eine Gegendruckrolle 22 gegenüber. Jede Gegendruckrolle 22 ist an einem Ende eines Hebels 23 drehbar gelagert, der um eine durch sein anderes Ende geführte Achse 24 schwenkbar ist. An diesem Ende trägt der Hebel 23 auf der dem zugeordneten Führungskanal zugewandten Seite einen Klemmgummi 25. Auf die Hebel 23 wirkt jeweils eine Feder 26 in der Weise ein, daß die Gegendruckrollen 22 gegen ihre jeweils zugeordnete Transportwalze 20 gedrückt werden. Die den Hebeln 23 zugewandten Leitbleche 18,19 der einzelnen Führungskanäle sind mit Öffnungen 27 versehen, die sich jeweils über die Breite der Gegendruckrolle 22 und in Längsrichtung über die Gegendruckrolle 22 und den Klemmgummi 25 hinaus erstrecken, so daß diese bei entsprechender Verschwenkung des Hebels 23 oder des Führungskanals mit der Papierbahn 4 in Berührung gebracht werden können.On the opposite side of each guide channel, the associated transport roller 20 is opposite a counter pressure roller 22. Each counter-pressure roller 22 is rotatably mounted on one end of a lever 23 which is pivotable about an axis 24 guided through its other end. At this end, the lever 23 carries a clamping rubber 25 on the side facing the associated guide channel. A spring 26 acts on the lever 23 in such a way that the counter-pressure rollers 22 are pressed against their respectively assigned transport roller 20. The guide plates 18, 19 of the individual guide channels facing the levers 23 are provided with openings 27, each of which extends over the width of the counterpressure roller 22 and extend in the longitudinal direction beyond the counter-pressure roller 22 and the clamping rubber 25, so that these can be brought into contact with the paper web 4 when the lever 23 or the guide channel is pivoted accordingly.

Jeweils zwei Führungskanälen ist eine nockenförmige Selektionsrolle 28 zugeordnet, durch deren Drehung die Führungskanäle verschwenkt werden können. Alle Selektionsrollen 28 werden durch einen Schrittmotor 29 gemeinsam angetrieben. Die Selektionsrollen 28 sind so ausgebildet und gegeneinander versetzt, daß jeweils nur eine Transportwalze 20 mit der Papierbahn 4 in einem der beiden zugeordneten Führungskanäle in Eingriff gebracht werden kann, während die Papierbahnen 4 in den anderen Führungskanälen außer Eingriff mit der jeweiligen Transportwalze 20 sind. Die Steuerung des Schrittmotors 29 erfolgt in der Weise, daß er in jeder Stellung, in der eine Transportwalze 20 mit einer Papier­bahn 4 in Eingriff ist, sowie in einer weiteren Stellung, in der sämtliche Transportwalzen 20 und Papierbahnen 4 außer Eingriff sind, angehalten werden kann.A cam-shaped selection roller 28 is assigned to two guide channels, the rotation of which allows the guide channels to be pivoted. All selection rollers 28 are driven together by a stepper motor 29. The selection rollers 28 are designed and offset from one another such that in each case only one transport roller 20 can be brought into engagement with the paper web 4 in one of the two associated guide channels, while the paper webs 4 in the other guide channels are disengaged from the respective transport roller 20. The stepper motor 29 is controlled in such a way that it can be stopped in any position in which a transport roller 20 is engaged with a paper web 4, as well as in a further position in which all the transport rollers 20 and paper webs 4 are disengaged .

Da die Gegendruckrollen 22 breiter sind als die Öffnungen 21 in dem jeweils abgewandten Leitblech 18 bzw. 19 des zugeordneten Führungs­kanals, werden die miteinander verbundenen Leit­bleche 18 und 19 jedes Führungskanals durch die Feder 26 zur jeweiligen Transportwalze 20 hin vorgespannt. Die auf der anderen Seite der Führungskanäle liegenden Selektionsrollen 28 verhindern jedoch den Kontakt mit den Transport­walzen 20. Je nach der Stellung der Selektions­rollen 28 kann lediglich jeweils einer der Führungskanäle, gemäß Fig. 3 der oberste, durch Wirkung der zugeordneten Feder 26 so stark verschwenkt werden, daß die feststehende Transport­walze 20 durch das zugewandte Leitblech 18 bzw. 19 hindurchtritt und die Papierbahn 4 durch die Gegendruckrolle 22 gegen diese gedrückt wird, so daß bei entsprechender Drehung der Transport­walze 20 die Papierbahn 4 vorgeschoben oder zurück­gezogen werden kann. Die anderen Führungskanäle werden von den zugeordneten Selektionsrollen 28 in Abstand von den Transportwalzen 20 und jeweils in Kontakt mit einen Klemmgummi 25 ge­halten, der durch die Öffnung 27 greift und die Papierbahn 4 gegen das gegenüberliegende Leitblech 18 bzw. 19 drückt, so daß sie gegen ein unabsichtliches Verschieben gesichert ist.Since the counter-pressure rollers 22 are wider than the openings 21 in the respectively facing baffle 18 and 19 of the associated guide channel, the interconnected guide plates 18 and 19 of each guide channel are biased by the spring 26 toward the respective transport roller 20. The selection rollers 28 lying on the other side of the guide channels however, prevent contact with the transport rollers 20. Depending on the position of the selection rollers 28, only one of the guide channels, according to FIG. 3 the top one, can be pivoted so much by the action of the associated spring 26 that the fixed transport roller 20 through the facing guide plate 18 or 19 passes and the paper web 4 is pressed against it by the counterpressure roller 22, so that the paper web 4 can be advanced or retracted with a corresponding rotation of the transport roller 20. The other guide channels are held by the associated selection rollers 28 at a distance from the transport rollers 20 and in each case in contact with a clamping rubber 25 which extends through the opening 27 and presses the paper web 4 against the opposite guide plate 18 or 19, so that it against one unintentional moving is secured.

Soll die Papierbahn 4 in einen anderen Führungskanal transportiert werden, dann wird der Schrittmotor 29 so betätigt, daß derjenige Führungskanal, der in Eingriff mit einer Transportwalze 20 stand, von dieser weggeschwenkt wird, während der ausgewählte Führungskanal gegen die zugeordnete Transportwalze 20 geschwenkt wird. Die anderen Führungskanäle bleiben außer Eingriff mit ihren Transportwalzen 20.If the paper web 4 is to be transported into another guide channel, then the stepping motor 29 is actuated so that the guide channel which was in engagement with a transport roller 20 is pivoted away from the latter, while the selected guide channel is pivoted against the assigned transport roller 20. The other guide channels remain out of engagement with their transport rollers 20.

Alle Transportwalzen 20 werden gemeinsam durch einen vorzugsweise als Schrittmotor ausgebildeten, umkehrbaren Motor 30 angetrieben. Während eines Selektionsvorganges, d.h. während der Drehung der Selektionsrollen 28 durch den Schrittmotor 29 ist der Motor 30 stillgesetzt.All transport rollers 20 are driven together by a reversible motor 30, which is preferably designed as a stepping motor. During a selection process, ie during the rotation of the selection rollers 28 by the stepper motor 29 the engine 30 is stopped.

Die Anzahl der Führungskanäle ist auch bei der Ausbildung gemäß Fig. 3 nicht auf vier beschränkt. Es können weitere Führungskanäle übereinander oder nebeneinander angeordnet vorgesehen sein.The number of guide channels is also not limited to four in the embodiment according to FIG. 3. Further guide channels can be provided one above the other or next to one another.

Das Vorschieben und Zurückziehen der Papierbahnen 4 erfolgt in gleicher Weise wie bei der Aus­bildung nach Fig. 1 durch entsprechend ge­steuerten Antrieb der Transportwalzen 20, wobei nur die Transportwalze 20 wirksam ist, die jeweils in Eingriff mit einem Führungskanal steht.The paper webs 4 are advanced and retracted in the same way as in the embodiment according to FIG. 1 by a correspondingly controlled drive of the transport rollers 20, only the transport roller 20, which is in engagement with a guide channel, being effective.

Die Vorrichtung nach Fig. 3 weist weiterhin ein Paar Einzugsrollen 31, 32 auf. Diese übernehmen keine Transportfunktion, sondern haben den Zweck, die jeweils vorgeschobene Papierbahn 4 am Eingang der Druckvorrichtung zu fixieren, wodurch die Druckqualität erhöht wird. Die Steuerung des Papiervorschubs und -rückzugs hingegen erfolgt ausschließlich über die Transport­walzen 20.3 also has a pair of feed rollers 31, 32. These do not take on a transport function, but have the purpose of fixing the respectively advanced paper web 4 at the input of the printing device, which increases the printing quality. The paper feed and retraction, on the other hand, is controlled exclusively via the transport rollers 20.

Die Einzugsrolle 31 wird im Uhrzeigersinn durch einen Gleichstrommotor 33 mit geringer Leistung angetrieben. Dieser ist so ausgelegt, daß er die Einzugsrolle 31 im lastfreien Zustand etwas schneller antreibt als es der Vorschubgeschwindig­keit der von der Transportwalze 20 vorgeschobenen Papierbahn 4 entspricht. Durch die Reibwirkung zwischen der Papierbahn 4 und der Einzugsrolle 31 wird der Gleichstrommotor 33 etwas abgebremst, wobei die Papierbahn 4 zwischen der Transportwalze 20 und der Einzugsrollen 31, 32 straff gehalten wird.The feed roller 31 is driven clockwise by a low power DC motor 33. This is designed in such a way that it drives the feed roller 31 somewhat faster in the load-free state than it corresponds to the feed speed of the paper web 4 fed by the transport roller 20. The DC motor 33 is braked somewhat by the frictional action between the paper web 4 and the feed roller 31, the paper web 4 being between the transport roller 20 and the feed rollers 31, 32 are kept taut.

In der Triebverbindung zwischen dem Gleichstrom­motor 33 und der Einzugsrolle 31 befindet sich eine Kupplung 34. Diese trennt diese Triebverbindung, wenn eine Papierbahn 4 durch eine Transportwalze 20 zurückgezogen wird, so daß der Gleichstrommotor 33 diesen Rückzug nicht behindert oder erschwert.In the drive connection between the DC motor 33 and the feed roller 31 there is a clutch 34. This separates this drive connection when a paper web 4 is pulled back by a transport roller 20, so that the DC motor 33 does not hinder or make this withdrawal difficult.

Die Vorrichtung nach Fig. 3 enthält schließlich auch eine Vorsteckeinrichtung zum Zuführen von Papier zur Druckvorrichtung außerhalb der Zuführungskanäle. Dieses Papier wird auf einen Anlegetisch 35 nach rechts gegen ein Paar Rollen 36, 37 geschoben. Die Rolle 36 wird von einem umkehrbaren Schrittmotor 38 über einen Treibriemen 39 angetrieben, der auch die Trieb­verbindung zwischen dem Gleichstrommotor 33 und der Einzugsrolle 31 bildet.Finally, the device according to FIG. 3 also contains a plug-in device for feeding paper to the printing device outside the feed channels. This paper is pushed onto a feed table 35 to the right against a pair of rollers 36, 37. The roller 36 is driven by a reversible stepper motor 38 via a drive belt 39, which also forms the drive connection between the DC motor 33 and the feed roller 31.

Eine Lichtschranke 40 erfaßt die Vorderkante des vorgeschobenen Papiers und bewirkt die Ein­schaltung des Schrittmotors 38 sowie die Trennung der Triebverbindung zwischen dem Gleichstrommotor 33 und dem Treibriehmen 39 durch die Kupplung 34. Die Rolle 36 transportiert das Papier weiter nach rechts, bis dessen Vorder­kante von der auch den Motor 30 steuernden Licht­schranke 17 erfaßt wird. Der Schrittmotor 38 wird hierauf stillgesetzt und der Druckvorgang wird ausgelöst; anschließend wird der Schrittmotor 38 in umgekehrter Richtung gedreht, so daß das Papier wieder aus der Druckvorrichtung herausbefördert wird.A light barrier 40 detects the leading edge of the advanced paper and causes the stepping motor 38 to be switched on and the drive connection between the direct current motor 33 and the driving frame 39 to be disconnected by means of the coupling 34. The roller 36 transports the paper further to the right until its leading edge is separated from that the light barrier 17 controlling the motor 30 is detected. The stepper motor 38 is then stopped and the printing process is triggered; then the stepper motor 38 is rotated in the reverse direction so that the paper is fed out of the printing device again.
