The device (1) for processing at least one strip of forms by means of controlled or clocked advancement of said strip (B1) has at least one guide (12) for said strip extending towards a crosswise separating device (11) therefor. The device comprises a mechanism (17; 162) for controlling the advancement of the strip. The mechanism for advancing the strip has a driven roller (182) for each strip, extending perpendicularly to the working direction over the working width of the device and cooperates with at least one pressing device (192), i.e. at least one non-driven idling roller or several of such rollers, in order to advance said strip. The driven roller has a continuous main shaft (20) which is joined on the ends thereof to a drive for rotation of the continuous main shaft. At least one pair of cylindrical bushings (21; 22) which can rotate around said main shaft and interact with each other by means of a differential gear (24) are borne on the main shaft.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Verarbeitung von Formularbahnen durch taktweises Vorschieben und Schneiden von Formularbahnen; solche Vorrichtungen sind z.B. aus dem deutschen Gebrauchsmuster G 85 04 658 (1985) sowie aus EP-A-0 156 775 bekannt. Vortichtungen dieser Art werden insbesondere für das automatisierte Verarbeiten von Endiosformularen, d.h. für die Bahntrennung sowie das Zusammenführen der zusammen gehörenden Abschnitte und in der Regel auch zum Kuvertieren, verwendet.The present invention relates to a device for processing form webs by advancing and cutting form webs in cycles; such devices are e.g. from the German utility model G 85 04 658 (1985) and from EP-A-0 156 775 known. Devices of this type are used in particular for automated Processing endios forms, i.e. for web separation and merging the sections that belong together and usually also for inserting, used.

EP-A-0 510 324 betrifft ebenfalls die Verarbeitung von Endlosformularen. Hierbei werden die Bahnen mit Hilfe von an diesen anliegenden und umlaufenden Bändern transportiert.EP-A-0 510 324 also relates to the processing of continuous forms. Here are the webs are transported with the help of belts which abut and circulate around them.

Zum technologischen Hintergrund gehört schliesslich EP-A-0 556 640, die eine sogenannte Capstan-Walze für Thermodrucker beschreibt. Die Walze für das zu bedruckende Papier besteht aus drei Segmenten, die über einen Differentialantrieb miteinander in Verbindung stehen, um die mittlere Geschwindigkeit der beiden Endsegmente an die Geschwindigkeit des Mittelsegmentes anzugleichen.Finally, EP-A-0 556 640 belongs to the technological background Capstan roller for thermal printers describes. The roller for what is to be printed Paper consists of three segments that are connected to each other via a differential drive Connected to the average speed of the two end segments Adjust the speed of the middle segment.

Bei Vorrichtungen der im Eingangsabsatz umschriebenen Art werden die Formularbahnen, die kontinuierlich oder diskontinuierlich bzw. taktweise vorgeschoben und quer zur Arbeitsrichtung in Einzelabschnitte vorbestimmter Länge zertrennt. Der Vorschub erfolgt bei diesen Einrichtungen mittels sogenannter Traktoren, d.h. Stachelräder oder Stachelbänder, deren Stacheln in die übliche Randlochung an einer oder beiden Seite(n) der Formularbahn eingreifen. Die Steuerung des Vorschubs kann mechanisch oder elektrisch bzw. elektronisch und beispielsweise elektro-optisch erfolgen, z.B. durch ein Programm oder/und durch Formularmarkierungen und entsprechend den jeweiligen Anforderungen an die Formularlänge.In the case of devices of the type described in the input paragraph, the form webs, which are advanced continuously or discontinuously or cyclically and across Working direction separated into individual sections of predetermined length. The feed takes place in these facilities by means of so-called tractors, i.e. Barbed wheels or barbed tapes, whose spines in the usual edge perforation on one or both sides of the Intervene form web. The control of the feed can be mechanical or electrical or electronically and for example electro-optically, e.g. through a program or / and through form markings and according to the respective requirements to the form length.

Allgemein wurde in der Fachwelt angenommen, dass eine solche Art des Vorschubs am genauesten mit Stachelrädern oder-bändern und entsprechend randseitig perforierten Formularbahnen erzielt werden kann. Man nahm daher den Nachteil in Kauf, dass Randlochpapier verwendet werden muss und Einrichtungen zum Abtrennen der seitlichen Randlochstreifen erforderlich sind. Überdies verursachen die abgetrennten Randlochstreifen ein erhebliches Papierabfallvolumen, das abgeführt und entsorgt werden muss.It was generally accepted in the professional world that such a type of feed on most precise with spiked wheels or ribbons and correspondingly perforated on the edge Form webs can be achieved. The disadvantage was therefore accepted that Perforated paper must be used and facilities for separating the side Edge tape is required. In addition, the severed border strips cause a significant volume of waste paper that is removed and disposed of got to.

Es wäre daher wünschbar, über eine Vorrichtung der eingangs genannten Art zu verfügen, welche die Verwendung von Randlochpapierbahnen vermeiden und dennoch einen genauen Vorschub der Formularbahnen ermöglichen würde. Aufgabe der Erfindung ist es, eine Vorrichtung anzugeben, die diese Anforderungen erfüllt, so dass Papierbahnen ohne Randlochstreifen verwendet werden können, kein Abfall durch abgetrennte Randstreifen entsteht und keine Einrichtungen zum seitlichen Beschneiden der Formularbahnen bzw. der aus diesen gebildeten Formularen erforderlich sind.It would therefore be desirable to have a device of the type mentioned at the beginning, which avoid the use of perforated paper webs and still a would enable precise feed of the form webs. The object of the invention is es to provide a device that meets these requirements so that paper webs can be used without edge tape, no waste due to separated edge strips arises and no facilities for lateral trimming of the form webs or the forms created from these are required.

Nicht zum gewünschten Ergebnis führten Versuche, anstelle der Traktoren zum Vorschub von Formularbahnen die üblichen Transporteinrichtungen mit Walzenpaaren zu verwenden, wie sie zur laufenden Verarbeitung von Papier-, Kunststoff- oder Textilbahnen verwendet werden und typisch mindestens ein Walzenpaar mit gegenläufigem Antrieb zum taktweisen Vorschub der Bahnen zu einer Verarbeitungs- bzw. Schneidestation aufweisen.Attempts to achieve the desired result instead of the tractors did not lead to the desired result from form webs to the usual transport devices with pairs of rollers use as they are for the ongoing processing of paper, plastic or textile webs are used and typically at least one pair of rollers with opposite drive for the cyclical feed of the webs to a processing or cutting station.

US-A-4 555 967 betrifft eine kontinvierliche Bahnführungs-Vorrichtung , wobei zum querschneiden den Bahui der Bahnvorschub nicht Unterbrochen wird.US-A-4 555 967 relates to one continuous web guiding device , whereby to cross the Bahui the Path feed not interrupted becomes.

US-A-3 552 903 offenbart eine Bannführungs vorrichtung mit einem Ausgleichsgetriebe in einem kontinvierlich angetriebenen Bahnaufwickelsystem.US-A-3 552 903 a ban guidance device with a differential in a continuous driven web winding system.

Die zur vorliegenden Erfindung führenden Untersuchungen haben insbesondere gezeigt, dass auf diese Weise die fiir zeitgemässe Vorrichtungen zur Verarbeitung von bedruckten Papierbahnen mit den erforderlichen hohen Verarbeitungsgeschwindigkeiten von 1-4 m/sec und der erforderlichen Vorschubgenauigkeit nicht erreicht werden kann, insbesondere nicht bei längerem Betrieb und der dann unvermeidlichen Veränderung der Wechselwirkung zwischen Formularbahn und Walze, z.B. als Folge von Verunreinigungen, Papierstaub und dergleichen.The investigations leading to the present invention have shown in particular that in this way the for contemporary devices for processing printed Paper webs with the required high processing speeds of 1-4 m / sec and the required feed accuracy cannot be achieved, in particular not with prolonged operation and the then inevitable change in the Interaction between form web and roller, e.g. as a result of contamination, Paper dust and the like.

Überraschender Weise kann die oben definierte Aufgabe der Erfindung dadurch gelöst werden, dass die Formularbahn zum Erzielen eines ausreichend genauen und richtungsgetreuen Vorschubs auf eine angetriebene Walze gerührt wird, die mit mindestens einer Andrückeinrichtung. z.B. mindestens einer anliegenden aber nicht angetriebenen Mitläu ferrolle oder einer anderen gleichwirkenden Einrichtung zusammenwirkt und zwei Teile besitzt, die durch ein Ausgleichsgetriebe miteinander verbunden sind, um Ungleichmässigkeiten des Vorschubs auszugleichen, wie sie sich z.B. durch Verunreinigungen oder andere Nebenerscheinungen eines schnellen und anhaltenden Betriebs der Vorrichtung ergeben können.Surprisingly, the object of the invention defined above can thereby be achieved be that the form web to achieve a sufficiently accurate and accurate Feed is stirred on a driven roller with at least one Pressing device. e.g. at least one adjacent but not driven joint ferrolle or another equivalent device cooperates and two parts owns, which are connected by a differential gear to unevenness to compensate for the feed, e.g. due to contamination or other side effects of rapid and sustained operation of the device can result.

Hierzu kann gemäss einer ersten allgemeinen und bevorzugten Ausführungsform der Erfindung auf der durchgehenden Hauptachse, die sich über die Arbeitsbreite der Vorrichtung (d.h. über die Breite der verarbeiteten Bahn) erstreckt und nur an einer Seite mit einem Antrieb zur Rotation der Achse verbunden ist, mindestens ein Hülsenpaar angeordnet werden, das drehbar und bezüglich der Längsmittellinie der zugehörigen Formularbahn im wesentlichen symmetrisch angeordnet ist, wobei die an der Längsmittellinie benachbarten Hülsen über ein Ausgleichsgetriebe verbunden sind. Das Ausgleichsgetriebe besitzt zwei Kegelräder, von denen jedes drehstarr mit den an der Längsmittellinie benachbarten Hülsen des mindestens einen Hülsenpaares verbünden ist; die Wirkungsverbindung dieser Kegelräder erfolgt über zwei Ausgleichskegelräder, die frei um eine gemeinsame Achse drehbar sind, welche senkrecht zur Hauptachse, z.B. in einer entsprechenden quer verlaufenden Bohrung der Hauptachse, angeordnet ist.According to a first general and preferred embodiment of the invention on the continuous main axis, which extends across the working width of the device (i.e. across the width of the web being processed) and only on one side with one Drive for rotation of the axis is connected, at least one pair of sleeves arranged be that rotatable and with respect to the longitudinal center line of the associated form web is arranged substantially symmetrically, with those adjacent to the longitudinal center line Sleeves are connected via a differential gear. The differential gear has two bevel gears, each of which is torsionally rigid with those adjacent to the longitudinal center line Sleeves of the at least one pair of sleeves is connected; the operative connection This bevel gear is made up of two differential bevel gears that freely move around one common axis are rotatable, which is perpendicular to the main axis, e.g. in a corresponding transverse bore of the main axis is arranged.

Das erfindungsgemässe Ausgleichsgetriebe hat eine analoge Wirkung, wie das bekannte Differentialgetriebe auf die angetriebenen Räder eines Autos, das eine Kurve durchfährt, wodurch sich die Antriebsgeschwindigkeit der Räder den unterschiedlichen Radien der von jedem Rad durchlaufenen Kurve anpasst. Nur bei gerader Fahrtstrecke - hier bei exaktem Geradeauslauf der jeweiligen Formularbahn - werden beide Hülsen mit genau gleicher Geschwindigkeit angetrieben. Das erfindungsgemäss verwendete Ausgleichsgetriebe zwischen den benachbarten Hülsen auf der Hauptachse bewirkt, dass bei einer seitlichen Abweichung von der normalen geraden Laufrichtung der Formularbahn die Abweichung durch das Ausgleichsgetriebe selbsttätig kompensiert und korrigiert wird.The differential gear according to the invention has an effect analogous to that known Differential gear on the driven wheels of a car making a turn whereby the driving speed of the wheels the different radii of the adapts to the curve traversed by each wheel. Only on a straight route - here with an exact one Straight line of the respective form web - both sleeves are exactly driven at the same speed. The differential gear used according to the invention between the adjacent sleeves on the main axis causes a lateral deviation from the normal straight running direction of the form web Deviation is compensated and corrected automatically by the differential.

Gemäss einer ersten allgemeinen Ausführungsform betrifft die Erfindung daher eine Vorrichtung zur Verarbeitung von Formularbahnen durch taktweisen Vorschub und Schneiden mindestens einer Formularbahn mit den in Patentanspruch 1 angesehenen Merkmalen.

Bei einem solchen mechanischen Getriebe sind die Antriebs- und/oder die Ausgleichskegelräder gemäss einer bevorzugten Ausführungsform als Zahnkegelräder ausgebildet, vorzugsweise selbstschmierend, d.h. mindestens jeweils eines der ineinander greifenden Kegelräder bzw. Zahnkegelräder besteht mindestens aussenseitig aus einem selbstschmierenden Polymer, wie Polyamid, Polyacetal, Polyester. Die Optimierung der Materialauswahl für die Räder des Ausgleichsgetriebes und auch für alle anderen Teile der erfindungsgemässen Vorrichtung liegt im Bereich der Kenntnis der Fachleute.In such a mechanical transmission, the drive and / or differential bevel gears according to a preferred embodiment, designed as toothed bevel gears, preferably self-lubricating, i.e. at least one of the interlocking ones Bevel gears or toothed bevel gears consist at least on the outside of a self-lubricating one Polymer such as polyamide, polyacetal, polyester.

Im allgemeinen sind die Frikrionsflächen. d.h. die mit der zugehörigen Formularbahn in Kontakt kommende Oberfläche der durch das Ausgleichsgetriebe bewegungsverbundenen Hülsen mit einem abriebfesten Elastomer, insbesondere einem gummielastischen Material, z.B. synthetischem oder natürlichem Elastomer, wie Kautschuk, Polyurethan. Polyisopren, oder dergleichen belegt, das typisch eine Shorehärte A im Bereich von 80 - 100 typisch 90 -95, hat. In general, the friction surfaces. i.e. with the associated form web in Contact coming surface of the movement-connected by the differential gear Sleeves with an abrasion-resistant elastomer, especially an elastic one Material, e.g. synthetic or natural elastomer, such as rubber, polyurethane. Polyisoprene, or the like, which typically has a Shore hardness A in the range of 80-100 typically 90-95.

Ferner kann die Friktionswirkung der Hülsenoberfläche auch durch die Oberflächenbeschaffenheit bzw. Oberflächenstrukturierung erzielt werden, z.B. durch Oberflächenrauhigkeit und/oder musterartige oder statistisch verteilte Profilierungen erfolgen. Hierfür können auch Oberflächen bzw. Oberflächenbereiche aus abriebbeständigen Werkstoffen verwendet werden einschliesslich von Metall, Keramik, Glas und Hartstoffen (Sintermetall, Metallcarbid, Nitridbeschichtungen, Diamant, Bornitrid), z.B. in der Form von Einbettung ausreichend feiner Körner aus solchen Hartstoffen in einer Schicht aus metallischem oder nichtmetallischem Bindemittel.Furthermore, the friction effect of the sleeve surface can also be due to the surface condition or surface structuring can be achieved, e.g. due to surface roughness and / or pattern-like or statistically distributed profiles. Therefor can also create surfaces or surface areas made of abrasion-resistant materials including metal, ceramics, glass and hard materials (sintered metal, Metal carbide, nitride coatings, diamond, boron nitride), e.g. in the form of Embedding sufficiently fine grains of such hard materials in a layer of metallic or non-metallic binder.

Auch für die Wahl der Friktionsoberfläche liegt eine optimierende Materialauswahl unter Berücksichtigung der obigen Angaben wiederum im Bereich des fachmännischen Wissens.There is also an optimizing material selection for the choice of the friction surface Taking the above information into account again in the area of professional Knowledge.

Im allgemeinen dienen zur Führung der Formularbahn in Längsrichtung mindestens zwei einander gegenüberliegende Kontaktstellen zum Anliegen an den beiden Seitenkanten der Formularbahn. Vorzugsweise sind Kontaktstellenpaare in Arbeitsrichtung der Vorrichtung, d.h. der Laufrichtung der Bahnen, voneinander mindestens um die Arbeitsbreite der Vorrichtung beabstandet, und zwar vor der zugehörigen angetriebenen Walze. Es versteht sich, dass diese Kontaktstellen bzw. Kontaktstellenpaare positionierbar sind, sei es zur Anpassung an unterschiedliche Formularbreiten, sei es zur Feinregutierung der Formulareinführung.In general, at least serve to guide the form web in the longitudinal direction two opposing contact points for contacting the two side edges the form web. Pairs of contact points are preferably in the working direction Device, i.e. the running direction of the tracks, at least by the working width of each other the device spaced, in front of the associated driven roller. It goes without saying that these contact points or contact point pairs can be positioned, be it to adapt to different form widths or be it to fine-tune the Form Introduction.

Zum Betrieb der neuen Vorrichtung mit takt-weisem Vorschub der Formularbahn kann bei jedem Vorschubtakt der Formularbahn eine Beschleunigunesphase, eine Bewegungsphase und eine Bremsphase zugeord-net werden die Beschleunigungsphase wird durch ein der gewünschten Formularlänge entsprechendes Signal ausgelöst und die Regelung des Vorschubs der Formularbahn erfolgt an einem durch die Formularlänge bestimmten Punkt.To operate the new device with clock-wise The form web can be fed at every feed cycle of the form web an acceleration phase, a movement phase and a braking phase are assigned The acceleration phase will be determined by a form length that corresponds to the desired length The signal is triggered and the feed of the form web is regulated a point determined by the length of the form.

Dabei besitzt die Formularbahn in an sich bekannter Weise, z.B. durch Aufdrucken erzeugte Markierungen, deren optische Ablesung das der gewünschten Formularlänge entsprechende Steuersignal auslöst; die Bewegung wird dabei durch eine an sich bekannte Regelelektronik kontrolliert, die den Ist-Wert des Vorschub-Auslösepunktes mit dessen Sollwert vergleicht und aus der Differenz die Regelung des Antriebs bewirkt.The form web has in a manner known per se, e.g. generated by printing Markings, the optical reading of which corresponds to the desired form length Control signal triggers; the movement is thereby known by a Control electronics that control the actual value of the feed trigger point with its Compares the setpoint and uses the difference to control the drive.

Die Erfindung wird nun anhand der beiliegenden Zeichnungen anhand von bevorzugten,aber nicht beschränkenden Ausführungsbeispielen erläutert. Es zeigen:

  • Figur 3 das Schema eines Vorschubtaktes und
  • Figur 4 die schematische Draufsicht auf eine Führung mit einer Formularbahn und der zugehörigen angetriebenen Walze.
    • The invention will now be explained with reference to the accompanying drawings using preferred, but not restrictive, exemplary embodiments. Show it:
  • Figure 1 is a schematic representation of a device according to the invention with a first and an optional second form web;
  • FIG. 2 shows a semi-schematic sectional view of the driven roller of a device according to the invention;
  • Figure 2a is an enlarged view of the differential gear of the roller of Fig. 2;
  • 3 shows the diagram of a feed cycle and
  • Figure 4 is a schematic plan view of a guide with a form web and the associated driven roller.

    • Die in Fig. 1 schematisch dargestellte Vorrichtung 1 besitzt eine erste Führung 12 für die Formularbahnen B1 und eine fakultative (durchbrochen gezeichnete) zweite Führung 14 fiir eine zweite Formularbahn B2. Die Anzahl der Führungsbahnen ist nur durch konstruktive Gegebenheiten und die Zahl der zu verarbeitenden Formularbahnen begrenzt.
    In analoger (nicht dargestellter Weise) könnten gewünschtenfalls auch drei oder mehr Formularbahnen zusammengeführt werden, sofern dies im gegebenen Fall räumlich möglich ist. Die Zahl der mit einer erfindungsgemässen Vorrichtung gleichzeitig verarbeiteten Bahnen wird nicht als kritisch angesehen und liegt im fachmannischen Ermessen.    The device 1 shown schematically in FIG. 1 has a first guide 12 for the form tracks B 1 and an optional (broken line) second guide 14 for a second form track B 2 . The number of guideways is only limited by the design and the number of form tracks to be processed.
    If desired, three or more form paths could also be merged in an analogous manner (not shown), provided that this is spatially possible in the given case. The number of webs processed simultaneously with a device according to the invention is not regarded as critical and is within the professional discretion.

    Bei Verwendung von mehr als einer Führung können die Führungen in an sich bekannter Weise konvergierend übereinander angeordnet werden. Dabei ist es bei Verwendung von mehr als einer Walze (und gleichzeitigen Verarbeitung von mehr als einer Formularbahn) nicht wesentlich, ob die Führungen jeweils mit der Horizontalen einen Winkel einschliessen oder eine der Führungen annähernd horizontal verläuft. Bei Verwendung einer einzigen Formularbahn kann die Führung 12 horizontal oder in einem Winkel zur Horizontalen angeordnet sein. Die Grösse dieses Winkels liegt wiederum im Bereich des fachmännischen Ermessens. If more than one guide is used, the guides can be known Be arranged converging one above the other. It is in use of more than one roller (and simultaneous processing of more than one form web) not essential whether the guides each make an angle with the horizontal include or one of the guides runs approximately horizontally. Using A single form web can guide 12 horizontally or at an angle be arranged to the horizontal. The size of this angle is again in the range of professional discretion.

    Die Formularbahn B1 und jede gegebenenfalls vorhandene weitere Formularbahn wird der Vorrichtung von einer nicht dargestellten Quelle, z.B. einem Magazin oder einer Längstrennvorrichtung für eine doppelseitig bedruckte Formularbahn, zugerührt. Jeder Formularbahn liegt seitlich an einer Führung 13 bzw. 15 an (nur die jeweils vorne liegende Führung ist dargestellt).The form web B 1 and any further form web which may be present are fed to the device from a source, not shown, for example a magazine or a longitudinal separating device for a double-sided printed form web. Each form web lies on the side of a guide 13 or 15 (only the guide in front is shown).

    Jede Formularbahn läuft zwischen der zugehörigen angetriebenen Walze 182 bzw. 184 und der daran unter leichtem Druck von typisch 50 - 500 g anliegenden Andrückeinrichtung, z.B. den nicht angetriebenen Anliege- oder Mitläuferrollen 192 bzw. 194 oder ähnlich wirkenden Andrückeinrichtungen, zur Quertrenneinrichtung 11, die z.B. in an sich bekannter Art als "Guillotine" mit einem Schneidbalken oder -messer und ein oder zwei Schneidkanten, als rotierendes Messer oder dergleichen ausgebildet sein kann. Wie bereits kurz angedeutet, können für jeder Walze auch mehrere Anliegeroller verwendet und/oder diese durch gleich- oder ähnlich wirkende Einrichtungen, z.B. anliegende Federn, Bügel oder dergleichen ersetzt bzw. wirkungsmässig ergänzt werden.Each form web runs between the associated driven roller 182 or 184 and the pressure device attached to it under slight pressure of typically 50 - 500 g, e.g. the non-driven contact or idler rollers 192 or 194 or similarly acting pressing devices to the cross-cutting device 11, which e.g. in on known type as "guillotine" with a cutting bar or knife and one or two cutting edges, can be designed as a rotating knife or the like. How Already briefly indicated, several contact rollers can be used for each roller and / or this by means of the same or similar effect, e.g. adjacent feathers, Brackets or the like can be replaced or effectively supplemented.

    Die Walze 182 bzw. 184 ist mit einem zugehörigen Antrieb 162 bzw. 164, z.B. einem Elektromotor, verbunden, dessen Aktivität von einer Steuerung 17 geregelt wird, um die mindestens eine Formularbahn zur Quertrenneinrichtung 11 zu führen.The roller 182 or 184 is equipped with an associated drive 162 or 164, e.g. one Electric motor, the activity of which is regulated by a controller 17 in order to to lead at least one form web to the cross cutting device 11.

    Der Aufbau der angetriebenen Walze 182 ist in Fig. 2 anhand einer halbschematischen Schnittdarstellung erläutert. Die Walze besitzt eine einstückige und durchgehende Hauptachse 20 aus einem starren Werkstoff, typisch Stahl, Aluminium oder dergleichen, die an beiden Enden 201, 202 drehbar in den Lagern 204, 205 geführt und an einer Seite, hier z.B. dem Ende 201, mit einem nicht dargestellten Antriebsmotor verbunden ist.The structure of the driven roller 182 in FIG. 2 is based on a semi-schematic one Sectional view explained. The roller has a one-piece and continuous Main axis 20 made of a rigid material, typically steel, aluminum or the like, which are rotatably guided at both ends 201, 202 in the bearings 204, 205 and on one side, here e.g. the end 201, is connected to a drive motor, not shown.

    Auf der Hauptachse 20 sind zwei Hülsen 21, 22 zwischen zwei mit der Achse 20 verbundenen Anschlagstücken 206, 207 drehbar um die Achse auf dieser geführt. Jede Hülse besteht typisch aus einem starren Werkstoff, wie Stahl, Aluminium oder Duroplast und ist mit einem Friktionsbelag 219, 229, z.B. aus einem elastischen Polyurethan (z.B. Vukollan® der Fa. Bayer AG) oder aus einer Beschichtung aus feinkörnigem Hartmaterial in einem geeigneten Matrixmaterial versehen. On the main axis 20, two sleeves 21, 22 are connected between two with the axis 20 Stop pieces 206, 207 rotatably guided about the axis on this. Every sleeve typically consists of a rigid material such as steel, aluminum or thermoset and is provided with a friction lining 219, 229, e.g. made of an elastic polyurethane (e.g. Vukollan® from Bayer AG) or from a coating of fine-grained hard material provided in a suitable matrix material.

    An jeder Hülse liegt im Bereich ihres Friktionsbelages 219, 229 die zugehörige Andrückrolle 29a, 29b an, um die Formularbahn ausreichend gegen den Friktionsbelag zu drücken, dass die (in Fig. 2 nicht eingezeichnete) Formularbahn bei Betätigung des (in Fig. 2 nicht dargestellten) Antriebs praktisch ohne Schlupf transportiert wird.The associated pressure roller lies on each sleeve in the area of its friction lining 219, 229 29a, 29b in order to adequately close the form web against the friction lining press that the form web (not shown in FIG. 2) when the (in Fig. 2, not shown) drive is transported practically without slippage.

    Die beiden Hülsen 21, 22 sind im Bereich der Mitte der Hauptachse 20 durch das Ausgleichsgetriebe 24 miteinander verbunden, wie dies vergrössert in Fig. 2a dargestellt ist. Das Ausgleichsgetriebe 24 besteht aus zwei Antriebskegel rädern 211, 221, die als Kegelzahnräder ausgebildet und jeweils drehstarr mit der zugehörigen Hülse 21, 22 verbunden sind. Die Wirkungsverbindung der Antriebskegelräder 211, 221 bzw. der mit diesen starr verbundenen Hülsen 21, 22 erfolgt durch zwei ebenfalls als Zahnräder ausgebildete Ausgleichskegelräder 261, 262, die um die Hilfsachse 28 frei drehbar sind und mit den Antriebskegelrädern 211, 221 in Eingriff stehen.The two sleeves 21, 22 are in the region of the center of the main axis 20 through the differential 24 connected to each other, as shown enlarged in Fig. 2a. The differential 24 consists of two drive bevel gears 211, 221, which act as bevel gears formed and each connected rigidly to the associated sleeve 21, 22 are. The operative connection of the drive bevel gears 211, 221 or with this rigidly connected sleeves 21, 22 is carried out by two also formed as gears Differential bevel gears 261, 262, which are freely rotatable about the auxiliary axis 28 and are engaged with the drive bevel gears 211, 221.

    Die Hilfsachse 28 liegt in einer Querbohrung der Hauptachse 20 und wird durch deren Drehung mitgenommen, d.h. rotiert in radialer Richtung. Die Hilfsachse 28 kann achsial drehbar sein, doch ist dies normalerweise ohne praktische Bedeutung. Wesentlich ist, dass das Ausgleichsgetriebe 24 nur dann zur Wirkung kommt, wenn die an der Formularbahn anliegenden Hülsen 21, 22 nicht gleichermassen am Transport beteiligt sind. Eine solche Ungleichheit kann z.B. dann auftreten, wenn im Dauerbetrieb Verschmutzungen durch Papierstaub oder dergleichen auftreten, was zur Folge hätte, dass die Formularbahn nicht mehr genau gerade, d.h. senkrecht zur Quertrenneinrichtung, läuft. In diesem Fall bewirkt das Ausgleichsgetriebe 24 eine sofortige Korrektur und gewährleistet dadurch auch im Dauerbetrieb mit typischen Laufgeschwindigkeiten der Formularbahnen von 1 bis 4m/sec eine zuverlässige Führung der Formularbahn.The auxiliary axis 28 lies in a transverse bore of the main axis 20 and is by the Rotation taken, i.e. rotates in the radial direction. The auxiliary axis 28 can be axial be rotatable, but this is usually of no practical importance. It is essential that the differential gear 24 only comes into effect when on the form web adjacent sleeves 21, 22 are not equally involved in the transport. Such an inequality can e.g. then occur if contamination occurs during continuous operation due to paper dust or the like, which would result in the form web not exactly straight anymore, i.e. perpendicular to the cross cutting device, runs. In in this case, the differential 24 causes an immediate correction and ensures therefore also in continuous operation with typical running speeds of the form webs reliable guidance of the form web from 1 to 4m / sec.

    Eine bevorzugte Steuerung bzw. Regelung des Antriebs der Hauptachse 20 ist im Diagramm von Fig. 3 dargestellt. Dabei wird der den Antrieb bewirkende Elektromotor so gesteuert, dass die zunächst stillstehende Formularbahn zunächst während einer Anlaufphase Bacc beschleunigt und dann mit praktisch gleichbleibender Geschwindigkeit durch die Bewegungs- oder Vorschubphase Bmov bis zum Beginn der Bremsphase Bbr geführt wird. Zur Regelung des Antriebs wird gemäss einer bevorzugten Ausführungsform des Betriebs der erfindungsgemässen Vorrichtung auf den Übergang der Phase Bmov zu Phase Bbr abgestellt und der Bremsvorgang dadurch so bemessen, dass die Formularbahn genau in der z.B. in üblicher Weise durch aufgedruckte Markierungen gesteuerten Position an der Quertrenneinrichtung positioniert wird.A preferred control or regulation of the drive of the main axis 20 is shown in the diagram of FIG. 3. The electric motor causing the drive is controlled in such a way that the initially stationary form web first accelerates during a start-up phase B acc and is then guided through the movement or feed phase B mov until the start of the braking phase B br at a practically constant speed. To regulate the drive, according to a preferred embodiment of the operation of the device according to the invention, the transition from phase B mov to phase B br is used and the braking process is dimensioned such that the form web is exactly in the position controlled in the usual manner, for example by printed markings Cross cutting device is positioned.

    Praktisch geschieht dies zweckmässigerweise so, dass jeder sequentiell-selektive Vorschubtakt der Formularbahn durch ein der gewünschten Formularlänge entsprechendes und durch Markierungen auf der Formularbahn ausgelöstes Signal erzeugt wird und die Regelung des Vorschubs der Formularbahn an dem durch die Formularlänge bestimmten Auslösepunkt erfolgt. Die Ablesung kann in an sich bekannter Weise z.B. durch optische Ablesung der Markierung auf der Formularbahn auslöst werden. Die Bewegung wird durch eine Regelelektronik kontrolliert, die den Ist-Wert der Lage des Auslösepunktes mit dessen Sollwert vergleicht und aus der Differenz die Regelung des Antriebs bewirkt.In practice, this expediently takes place in such a way that each sequential-selective feed cycle the form path by a corresponding to the desired form length and signal generated by markings on the form path is generated and the Regulation of the feed of the form web at the one determined by the form length Trigger point occurs. The reading can be carried out in a manner known per se e.g. through optical Reading of the marking on the form web can be triggered. The movement will controlled by control electronics, the actual value of the location of the trigger point compares it with its setpoint and uses the difference to control the drive.

    Fig. 4 zeigt einen abgebrochenen Teil der Führung 42 einer erfindungsgemässen Vorrichtung mit der darauf liegenden Formularbahn 43, die eine Mittellinie M und eine Breite B besitzt. Die randseitigen Führungen 45a, 45b sind in einem Abstand L in Laufrichtung (Pfeil A) vor der angetriebenen Walze 44 entfernt angeordnet, wobei der Abstand L vorzugsweise mindestens ebenso gross ist, wie die Breite B der Bahn 43. Die Andrückrollen 49a, 49b sind symmetrisch zur Mittellinie M der Formularbahn angeordnet und drücken die Formularbahn im Bereich der Friktionsbeläge gegen die Walze, die über die Achse 40 mit dem Antrieb 46 verbunden ist und die Betätigung der Walze in der oben dargelegten Weise steuert bzw. regelt.4 shows a broken part of the guide 42 of a device according to the invention with the form web 43 lying thereon, which has a center line M and a Width B has. The edge-side guides 45a, 45b are at a distance L in the running direction (Arrow A) located in front of the driven roller 44, the distance L is preferably at least as large as the width B of the web 43 Pressure rollers 49a, 49b are arranged symmetrically to the center line M of the form web and press the form web against the roller in the area of the friction linings is connected via the axis 40 to the drive 46 and the actuation of the roller in controls in the manner set out above.
