Abstract

Um eine grössere Anzahl Papiervorratsrollen (11-17) mit entsprechend einem grösserem Papiervorrat grösseren Durchmessern in einem Raum relativ kleiner Abmessungen unterzubringen, werden Vorratsrollen (12-15) auch nebeneinander, d. h. seitlich zu den Papiereinführungsschlitzen (21-27) der Druckmaschine (20) versetzt, angeordnet. Die in diesem Falle teils windschief zu der Papiereinführungsrichtung der Druckmaschine verlaufenden Wegstreckenabschnitte der Papierbahnen (2-5) werden durch Umlenkglieder (52/62, 53/63, 54/64, 55/65, 42-45) ermöglicht, an denen die Papierbahn auf einem Umlenkungsweg, der längs eines Teiles einer Schraubenlinienwindung verläuft, umgelenkt werden.In order to accommodate a larger number of paper supply rolls (11-17) with a correspondingly larger paper supply and larger diameters in a room of relatively small dimensions, supply rolls (12-15) are also placed next to one another, i. H. offset laterally to the paper insertion slots (21-27) of the printing press (20). The path sections of the paper webs (2-5), which in some cases are skewed to the paper insertion direction of the printing press, are made possible by deflection members (52/62, 53/63, 54/64, 55/65, 42-45) on which the paper web are deflected on a deflection path which runs along part of a helical turn.

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Zuführung der Papierbahnen mehrerer Vorratsrollen zu parallel nebeneinan­der angeordneten Papiereinführschlitzen einer Druckmaschine, insbesondere Fahrkartendruckmaschine, in der jeweils eine der eingeführten Papierbahnen zu einer Druckstation gefördert, be­druckt, das bedruckte Papierbahnstück abgeschnitten und ausge­geben wird.The invention relates to a device for feeding the paper webs of a plurality of supply rolls to parallel paper insertion slots of a printing machine, in particular a ticket printing machine, in which in each case one of the introduced paper webs is conveyed to a printing station, printed, the printed paper web piece is cut off and output.

Bei solchen Druckmaschinen werden die Papierbahnen den Schlit­zen über Umlenkrollen zugeführt, wobei die Führungsrichtungen in einer zu den Schlitzen senkrechten Ebene lagen, wozu die Vorratsrollen über- oder hintereinander und ihre Achsen sowie die Achsen aller Umlenkrollen parallel zu den Schlitzen ange­ordnet wurden.In such printing machines, the paper webs are fed to the slots via deflection rollers, the guide directions being in a plane perpendicular to the slots, for which purpose the supply rollers were arranged one above the other or one behind the other and their axes and the axes of all deflection rollers were arranged parallel to the slots.

Dabei nahm die Anordnung der Vorratsrollen einen entsprechend der Breite einer oder der breitesten Papierbahn bzw. Vorrats­rolle schmalen Gehäuseraum ein, an dessen vorderer Schmalseite die bedruckten und abgeschnittenen Papierbahnstücke (insbes. z. B. Fahrkarten) ausgegeben wurden. Uebereinander können nur wenige (z. B. drei) Vorratsrollen angeordnet werden; denn der gewünschte grosse Vorrat jeder Papierbahn erfordert Vorratsrol­len grossen Durchmessers, von denen auch die oberste zum Aus­wechseln vom Boden aus erreichbar sein soll. Eine Hintereinan­deranordnung der Vorratsrollen kommt wegen der dabei grossen Tiefenabmessung der Einrichtung praktisch kaum in Frage, denn derartige Einrichtungen (insbesondere z. B. Fahrkartenautoma­ten) werden meistens an einer Wand aufgestellt, an der sie nicht weit vorstehen sollen.The arrangement of the supply rolls took up a housing space corresponding to the width of one or the widest paper web or supply roll, on the front narrow side of which the printed and cut-off pieces of paper web (in particular, for example, tickets) were issued. Only a few (e.g. three) supply rolls can be arranged one above the other; Because the desired large stock of each paper web requires large diameter supply rolls, of which the top one should also be accessible from the ground for replacement. Arranging the supply rolls one behind the other is practically out of the question because of the large depth dimension of the device, because such devices (in particular, for example, ticket machines) are usually set up on a wall on which they should not protrude far.

Hier will die Erfindung Abhilfe schaffen. Durch die Erfindung, wie sie im Patentanspruch 1 gekennzeichnet ist, wird die Aufga­be gelöst, eine Einrichtung der eingangs genannten Art zu schaffen, die es ermöglicht, Papierbahnen von oder auch von seitlich zu den Schlitzen in Schlitzrichtung versetzt angeord­neten Vorratsrollen zu den Schlitzen zu führen, so dass Vor­ratsrollen auch in Achsenrichtung nebeneinander angeordnet wer­den können.The invention seeks to remedy this. By the invention as characterized in claim 1, the object is achieved to provide a device of the type mentioned, which makes it possible to guide paper webs from or to the slots from the side to the slots offset in the slot direction to the slots, so that supply rolls can also be arranged side by side in the axial direction.

Die durch die Erfindung erzielten Vorteile sind im wesentlichen darin zu sehen, dass mit nebeneinander angeordneten Vorratsrol­len auch bei einer verhältnismässig grossen Anzahl Vorratsrol­len mit verhältnismässig grossem Durchmesser und Bandvorrat ei­ne kompante raumsparende Anordnung ohne Vergrösserung der Tie­fenabmessung der Einrichtung erhalten wird.The advantages achieved by the invention are essentially to be seen in the fact that with supply rolls arranged next to one another, even with a relatively large number of supply rolls with a relatively large diameter and tape supply, a compact, space-saving arrangement is obtained without enlarging the depth dimension of the device.

Im folgenden wird die Erfindung anhand der beiliegenden, ledig­lich einen Ausführungsweg darstellenden, schematischen Zeich­nungen näher erläutert. Es zeigen

Mit der dargestellten Einrichtung werden sieben Papierbahnen 1-7 je von einer der Vorratsrollen 11-17 zu einer nicht näher dargestellten Druckmaschine 20, z. B. Fahrkartendruckmaschine, geführt, die für jede Papierbahn 1-7 einen von sieben Einfüh­rungsschlitzen 21-27 hat. In der Druckmaschine 20 wird jeweils eine der in die Schlitze 21-27 eingeführten Papierbahnen 1-7 zu einer nicht dargestellten Druckstation gefördert, bedruckt, das bedruckte Papierbahnstück abgeschnitten und ausgegeben. Eine solche Druckmaschine ist aus der EP-A-O 048 329 bekannt. Bei dieser bekannten (hier nicht näher dargestellten) Druckmaschine bilden die Schlitze 21-27 die Eingänge von Führungskanälen, die fächerartig zu einem Walzenpaar konvergierend angeordnet sind. Im Ruhezustand erstreckt sich jede Papierbahn bis zum Ausgang des für sie vorgesehenen Führungskanals. Jeder Führungskanal ist mit einem Greifer ausgerüstet, der die Papierbahn in Ruhe­lage festhält. Der Greifer für die jeweils zu bedruckende Pa­pierbahn schiebt diese vor, bis sie in den Klemmspalt des ro­tierenden Walzenpaares gelaufen ist, lässt sie dann los und bleibt zunächst in seiner vorgeschobenen Stellung. Das Walzen­paar fördert die Papierbahn weiter zunächst in ihre Druckposi­tion, nach dem Bedrucken in ihre Abschneideposition und nach dem Abschneiden wieder rückwärts. Bevor die Papierbahn den Klemmspalt verlässt, greift der Greifer wieder zu und geht in seine Ruhestellung zurück, wobei er die Papierbahn mitnimmt, so dass deren durch das Abschneiden gebildetes Ende in die Stel­lung kommt, in der ihr vorheriges freies Ende vor dem Greifer­vorschub war. Auf diese Weise kann in beliebiger Reihenfolge auf verschiedene Papierbahnen und auch unmittelbar nacheinander auf ein und dieselbe Papierbahn gedruckt werden.With the device shown, seven paper webs 1-7 each from one of the supply rolls 11-17 to a printing machine 20, not shown, for. B. ticket printing machine, which has one of seven insertion slots 21-27 for each paper web 1-7. In the printing press 20, one of the paper webs 1-7 introduced into the slots 21-27 is conveyed to a printing station (not shown), printed, the printed paper web piece is cut off and output. Such a printing press is known from EP-AO 048 329. In this known (not shown here) printing machine, the slots 21-27 form the entrances of guide channels which are arranged in a fan-like manner converging to form a pair of rollers. In the idle state, each paper web extends to the exit of the guide channel provided for it. Each guide channel is equipped with a gripper that holds the paper web in the rest position. The gripper for the paper web to be printed in each case advances it until it has run into the nip of the rotating pair of rollers, then releases it and initially remains in its advanced position. The pair of rollers continues to feed the paper web first into its printing position, after printing into its cut-off position and backwards after cutting. Before the paper web leaves the nip, the gripper grabs again and goes in its rest position, taking the paper web with it, so that its end formed by the cutting comes into the position in which its previous free end was before the gripper advance. In this way it is possible to print on different paper webs in any order and also immediately one after the other on one and the same paper web.

Jeder der Vorratsrollen 11-16 ist eine der Umlenkrollen 31-36 zugeordnet, von der die Papierbahn in einer Richtung weiter­läuft, die unabhängig vom Durchmesser des Papierwickels ist, der mit abnehmenden Vorrat kleiner wird.Each of the supply rolls 11-16 is assigned one of the deflection rolls 31-36, from which the paper web continues in a direction which is independent of the diameter of the paper roll, which becomes smaller as the supply decreases.

Den Papierbahnen 1-6 ist auch ein im folgenden noch näher be­schriebener Tänzer 40 zugeordnet, der für jede dieser Papier­bahnen 1-6 ein Umlenkglied 41-46 hat, von dem die Papierbahn zu dem für sie vorgesehene der Schlitze 21-26 läuft.Also assigned to the paper webs 1-6 is a dancer 40, which is described in more detail below and which has a deflection member 41-46 for each of these paper webs 1-6, from which the paper web runs to the slot 21-26 provided for it.

Die Vorratsrollen 11, 16, 17 sind übereinander gelagert und ebenso wie die Umlenkrollen 31, 36, 37 und die Umlenkglieder 41, 46, 47 mit ihren Achsen bzw. Krümmungsachsen parallel zu den Schlitzen 21-27 so angeordnet, dass alle Wegabschnitte der Papierbahnen 1, 6 und 7 senkrecht zu den Schlitzen 21-27 ver­laufen. Dabei läuft die Papierbahn 1 längs eines Kreisbogens um die Umlenkrolle 31 und ebenso (d. h. wieder längs eines Kreis­bogens) an einer Gleitfläche des Umlenkgliedes 41 des Tänzers 40, die Papierbahn 6 läuft längs eines Kreisbogens um zwei Um­lenkrollen 36, 56 und ebenso an einer Gleitfläche des Umlenk­gliedes 46 des Tänzers 40, und die Papierbahn 7 läuft längs ei­nes Kreisbogens an einem durch ein Leitblech gebildeten Umlenk­glied 57. Dabei liegen alle geraden Wegabschnitte und alle kreisbogenförmigen Wegabschnitte und demgemäss alle Umlenkungs­winkel der Papierbahnen 1, 6 und 7 in einer zu den Einführungs­schlitzen 21-27 senkrechten Ebene.The supply rolls 11, 16, 17 are superimposed and, like the deflection rolls 31, 36, 37 and the deflection members 41, 46, 47, with their axes or axes of curvature arranged parallel to the slots 21-27 so that all path sections of the paper webs 1 , 6 and 7 are perpendicular to the slots 21-27. The paper web 1 runs along an arc around the deflection roller 31 and likewise (ie again along an arc) on a sliding surface of the deflection member 41 of the dancer 40, the paper web 6 runs along an arc around two deflection rollers 36, 56 and also on a sliding surface of the Deflection member 46 of the dancer 40, and the paper web 7 runs along a circular arc on a deflection member 57 formed by a guide plate. All straight path sections and all circular path sections and accordingly all deflection angles of the paper webs 1, 6 and 7 lie in one to the insertion slots 21- 27 vertical plane.

Die Vorratsrollen 12-15 sind seitlich zu den Einführungsschlit­zen 21-27 versetzt angeordnet, so dass die Vorratsrollen 12, 13 an einer (in Fig. 1 linken) und die Vorratsrollen 14, 15 an der anderen (in Fig. 1 rechten) Seite der Einführungschlitze 21-27 und der Vorratsrollen 11, 16, 17 sowie des über den Einfüh­rungsschlitzen 1-7 angeordneten Tänzers 40 sind. Im dargestell­ten Ausführungsbeispiel sind die Achsen der Vorratsrollen 12-15 parallel zu denen der Vorratsrollen 11, 16, 17 und zu den Ein­führungsschlitzen 21-27. Das ist nicht notwendig, ermöglicht es aber, die Vorratsrollen 12, 14 dicht neben der Vorratsspule 11 und die Vorratsspulen 13, 15 dicht neben der Vorratsspule 16 raumsparend anzuordnen.The supply rolls 12-15 are laterally offset from the insertion slots 21-27, so that the supply rolls 12, 13 on one (in FIG. 1 left) and the supply rolls 14, 15 on the other (in FIG. 1 right) side of the Are insertion slots 21-27 and the supply rollers 11, 16, 17 and the dancer 40 arranged above the insertion slots 1-7. In the exemplary embodiment shown, the axes of the supply rolls 12-15 are parallel to those of the supply rolls 11, 16, 17 and to the insertion slots 21-27. This is not necessary, but makes it possible to arrange the supply rolls 12, 14 close to the supply spool 11 and the supply spools 13, 15 close to the supply spool 16 in a space-saving manner.

Auf ihren schräg von hinten nach vorn seitwärts und auf- oder abwärts führenden Wegen müssen die Papierbahnen 2-5 um Winkel in Ebenen umgelenkt werden, die schräg zu den Achsen der Vor­ratsrollen 11-17 und schräg zu den Einführungsschlitzen 21-27 sind. Zu diesem Zwecke ist z. B. die Papierbahn 4 auf einem längs eines Teiles einer Schraubenlinienwindung verlaufenden Umlenkungsweges um ein durch eine drehbar gelagerte Rolle 54 mit einem Flansch 64 gebildetes Umlenkglied und danach wieder auf einem längs eines Teiles einer Schraubenlinienwindung ver­laufenden Umlenkungsweg über eine gewölbte Gleitfläche eines weiteren Umlenkgliedes 44 des Tänzers 40 geführt. Tatsächlich kann jeder erforderliche Umlenkwinkel in der erforderlichen Ebene durch zwei Tangenten einer Schraubenlinienwindung gebil­det werden (wobei unter dem Umlenkungswinkel der Winkel zu ver­stehen ist, den die zunächst windschiefen Tangenten einschlies­sen, wenn eine parallel so verschoben wird, dass sie die andere schneidet). Der längs eines Teiles einer Schraubenlinienwindung verlaufende Weg wird durch die Schräglage der Achse der Umlenk­rolle 54 mit dem Flansch 64 bzw. der Krümmungsachse des Umlenk­gliedes 44 und durch die Zufuhr- und die (beim Umlenkglied 44 praktisch vertikale) Abzugrichtung erzwungen. Das Papierband 4 ist bestrebt, auf die Umlenkrolle 54 an einer fortlaufend in Fig. 1 und 3 nach rechts, in Fig. 2 nach hinten wandernden Stelle aufzulaufen, so, wie das beim schraubenlinienförmigen Aufwickeln auf die Umlenkrolle 54 der Fall wäre. Um das zu ver­hindern, ist der Flansch 64 des Umlenkgliedes 54/64 konisch und an dem Ende der Rolle 54 angebracht oder gebildet, von dem der längs der Schraubenlinienwindung verlaufende Weg infolge der Steigung der Schraubenlinie wegführt. An diesem Ende läuft der Rand der Papierbahn 4 zuerst auf den Flansch 64. Während die Papierbahn 4 um das Umlenkglied 54/64 läuft, gleitet sie axial an der Rolle 54 in der vom Flansch 64 wegweisenden Richtung, so dass sie ihre seitliche Lage am Umlenkglied 54/64 beibehält. Wird das Umlenkglied 54/64 statt durch die Rolle 54 und den Flansch 64 mit einer feststehenden Gleitfläche gebildet, so er­übrigt sich eine dem Flansch 64 entsprechende, seitliche Füh­rung. Es hat sich gezeigt, dass es genügt, die Ränder der Pa­pierbahn 4 an den Enden des Einführungsschlitzes 24 zu führen.On their paths leading obliquely from back to front and upwards or downwards, the paper webs 2-5 must be deflected by angles in planes which are at an angle to the axes of the supply rollers 11-17 and at an angle to the insertion slots 21-27. For this purpose, e.g. B. the paper web 4 on a along a part of a helical winding deflection path around a deflection member formed by a rotatably mounted roller 54 with a flange 64 and then again on a along a part of a helical winding deflection path over a curved sliding surface of another deflection member 44 of the dancer 40 led. In fact, any required deflection angle in the required plane can be formed by two tangents of a helical turn (whereby the deflection angle is to be understood as the angle which the initially skewed tangents form when one is displaced in parallel so that it intersects the other). The path running along part of a helical turn is determined by the inclined position of the axis of the deflection roller 54 with the flange 64 or the axis of curvature of the deflection element 44 and by the feed and (in the deflection element 44 practically vertical) trigger direction forced. The paper tape 4 endeavors to run onto the deflection roller 54 at a point that continuously moves to the right in FIGS. 1 and 3, and to the rear in FIG. 2, as would be the case when winding onto the deflection roller 54 in a helical manner. In order to prevent this, the flange 64 of the deflection member 54/64 is conical and attached or formed at the end of the roller 54, from which the path running along the helix turn leads away due to the slope of the helix. At this end, the edge of the paper web 4 first runs onto the flange 64. While the paper web 4 runs around the deflection member 54/64, it slides axially on the roller 54 in the direction pointing away from the flange 64, so that it is positioned laterally on the deflection member 54/64 maintains. If the deflection member 54/64 is formed with a fixed sliding surface instead of the roller 54 and the flange 64, then a lateral guide corresponding to the flange 64 is unnecessary. It has been shown that it is sufficient to guide the edges of the paper web 4 at the ends of the insertion slot 24.

Die Achse des Umlenkgliedes 54/64 ist windschief zu den Achsen der Umlenkrolle 34 und der Vorratsspule 14, sowie zu den Schlitzen 21-27. Die Krümmungsachse des Umlenkgliedes 44 liegt in der Zufuhrebene der Schlitze 21-27 ist aber zur Schlitzrich­tung geneigt. Dabei liegen die beiden Umlenkungswinkel der Um­lenkglieder 54/64 und 44 in Ebenen, die schräg im Raum liegen. Dadurch wird die Papierbahn 4 auf zu allen drei senkrechten Ko­ordinaten (des z. B. durch die Zeichenebenen der Fig. 1-3 gege­benen Koordinatensystems) schrägen Wegstrecken von der Umlenk- rolle 34 bis zu dem Umlenkglied 44 am Tänzer 40 geführt, um schliesslich gerade in den Einführungsschlitz 24 der Druckma­schine 2 zu laufen.The axis of the deflection member 54/64 is skewed to the axes of the deflection roller 34 and the supply spool 14, as well as to the slots 21-27. The axis of curvature of the deflection member 44 lies in the feed plane of the slots 21-27 but is inclined to the slot direction. The two deflection angles of the deflection members 54/64 and 44 lie in planes that lie obliquely in space. As a result, the paper web 4 is guided on oblique paths to all three vertical coordinates (of the coordinate system given, for example, by the plane of the drawing in FIGS. 1-3) from the deflection roller 34 to the deflection member 44 on the dancer 40 in order to finally straighten to run into the insertion slot 24 of the printing press 2.

Die Papierbahnen 2, 3, 5 sind von den Umlenkrollen 32, 33, 35 zu den Schlitzen 22, 23, 25 entsprechend der Führung der Pa­pierbahn 4 von der Umlenkrolle 34 zum Schlitz 24 geführt, so dass das zur Führung der Papierbahn 4 und zu deren Führungs­gliedern 54/64 und 44 Gesagte sinngemäss für die Führung der Papierbahnen 2, 3, 5 und deren Führungsglieder 52/62, 42; 53/63, 43; 55/65, 45 gilt.The paper webs 2, 3, 5 are guided from the deflection rollers 32, 33, 35 to the slots 22, 23, 25 in accordance with the guidance of the paper web 4 from the deflection roller 34 to the slot 24, so that this is for guiding the paper web 4 and to it Guide members 54/64 and 44 said analogously for the guidance of the paper webs 2, 3, 5 and their guide members 52/62, 42; 53/63, 43; 55/65, 45 applies.

Beim Tänzer 40 sind die Umlenkglieder 41-46 mit ihren Enden an zwei annähernd vertikalen Holmen 81, 82 befestigt. Der dadurch gebildete Sprossenrahmen ist mittels einer Lenkergeradführung mit zwei Parallelogrammlenkern 83, 84 annähernd vertikal beweg­bar geführt. Eine Torsionsfeder 85 greift am Lenker 84 an und nimmt das Gewicht des Tänzers 40 und der auf ihn wirkenden Pa­pierbahnen 1-6 auf und gibt am Anfang des Vorschubs eines der an den Umlenkgliedern 41-46 des Tänzers liegenden Papierbahnen 1-6 vorübergehend nach, bis deren grössere Haftreibung in die kleinere Gleitreibung übergegangen ist. Dabei wird zuerst nur der Tänzer 40 bewegt, und erst dann wird die Papierbahn geför­dert und die drehbaren Umlenkglieder, um die sie läuft sowie die Vorratsspule angetrieben. Dadurch wird die auftretende Spannung der Papierbahn herabgesetzt und es genügt eine kleine­re Vorschubkraft der vorher bei der Erläuterung der Druckma­schine erwähnten Greifer.In the dancer 40, the deflection members 41-46 are attached with their ends to two approximately vertical bars 81, 82. The rung frame thus formed is guided in an approximately vertically movable manner by means of a straight handlebar guide with two parallelogram links 83, 84. A torsion spring 85 engages the handlebar 84 and takes up the weight of the dancer 40 and the paper webs 1-6 acting on it and at the start of the advance temporarily gives in to one of the paper webs 1-6 lying on the deflection members 41-46 of the dancer until whose greater static friction has changed into the smaller sliding friction. First, only the dancer 40 is moved, and only then is the paper web conveyed and the rotatable deflection members around which it runs and the supply spool are driven. This reduces the tension of the paper web and a smaller feed force of the grippers previously mentioned in the explanation of the printing press is sufficient.

Zweckmässig werden für jede Vorratsrolle ein (nicht dargestell­ter) Fühler, der beim Unterschreiten eines bestimmten Vorrats ein Signal an die Steuervorrichtung der Druckmaschine abgibt, und eine (nicht dargestellte) Bremse vorgesehen, durch welche die zur zuverlässigen Führung erforderliche Spannung der Pa­pierbahn sichergestellt und verhindert wird, dass die Vorrats­rolle sich infolge ihrer Trägheit nach einem Vorschubschritt der Papierbahn weiter dreht und die Papierbahn entspannt.For each supply roll, a sensor (not shown), which emits a signal to the control device of the printing machine when a certain supply is undershot, and a brake (not shown) are expediently provided, by means of which the tension of the paper web required for reliable guidance is ensured and prevented that the supply roll continues to rotate due to its inertia after a feed step of the paper web and the paper web relaxes.

In Fig. 2 sind die beiden Vorratsrollen 11, 14 und 15, 16 sowie die beiden Umlenkrollen 31, 34 und 35, 36 zueinander versetzt dargestellt, um den Verlauf der Papierbahn 1, 4 und 5, 6 ge­trennt zu zeigen. Selbstverständlich ist an Stelle der darge­stellten auch eine koaxiale Anordnung möglich.2, the two supply rolls 11, 14 and 15, 16 and the two deflection rolls 31, 34 and 35, 36 are shown offset from one another in order to show the course of the paper web 1, 4 and 5, 6 separately. Of course, a coaxial arrangement is also possible instead of the one shown.

An Stelle der Umlenkrollen 31-36 können auch Umlenkglieder mit ortsfester Gleitfläche verwendet werden, beispielsweise kann an Stelle der Umlenkrollen 31, 32, 34 ein erster und an Stelle der Umlenkrollen 33, 35 und 36 ein zweiter sich quer zur Einrich­tung erstreckender Rundstab vorgesehen werden.Instead of the deflection rollers 31-36, deflection members with a fixed sliding surface can also be used, for example a first round rod can be provided instead of the deflection rollers 31, 32, 34 and a second round rod extending transversely to the device, instead of the deflection rollers 33, 35 and 36.
