Abstract

A severing device (13) for individual forms which are joined together to form endless form webs (8). A severing rail (16) is arranged on a swivellable flap (15), the other edge of which constitutes a holding rail (17). For separating one form, the flap (15) is swivelled by pulling on the form and the holding rail (17) presses the form web (8) remaining in the machine against an abutment (21) so that the web is retained in the printing device. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Abreißvorrichtung mit einer Abreißschiene für Formularbahnen, die sich quer zu deren Transportrichtung erstreckt.The invention relates to a tear-off device with a tear-off rail for form webs, which extends transversely to the direction of transport.

-Für das Trennen von Formularsätzen gibt es bereits Schneidvorrichtungen, die die Formularbahnen entsprechend einer gewünschten Linie abschneiden. Derartige Schneidvorrichtungen sind relativ aufwendig, haben einen hohen Platzbedarf und gestatten es nur, alle Formulare einer mehrlagigen Formularbahn gleichzeitig zu durchtrennen.-For the separation of form sets, there are already cutting devices that cut the form tracks according to a desired line. Such cutting devices are relatively complex, take up a lot of space and only allow all forms of a multilayer form web to be cut at the same time.

Bekannt sind aber auch schon Abreißschienen beispielsweise bei Addiermaschinen, bei Schreibmaschinen, Fernschreibmaschinen, Textautomaten oder dergl., die es gestatten, eine endlose Formularbahn entlang einer sich quer zur Transportrichtung des Formulares über die Formularbahn erstreckenden Abreißschiene abzureißen.However, tear-off rails are also known, for example in the case of adding machines, typewriters, teleprinters, automatic text machines or the like, which allow an endless form web to be torn off along a tear-off rail extending transversely to the transport direction of the form over the form web.

In der US-PS 1 25o 883 und in der GB-PS 699 417 sind Einrichtungen beschrieben, bei denen quer zur Druckunterlage angeordnete Klappen vorgesehen sind, die an ihrer einen Längskante eine Abreißschiene haben, während die anderen Längskanten mit Haltenasen oder dergl. für das Papier ausgerüstet sind. In beiden Fällen handelt es sich um schwenkbare Klappen, die für die Papiereinführung weggeschwenkt werden müssen in ähnlicher Weise wie bei einer Schreibmaschine die oberen Andrückrollen. Im Falle der GB-PS 699 417 liegt der Schwenkpunkt der Klappe im hinteren Teil des Schienenrahmens außerhalb der Verbindungslinie zwischen der Abreißkante einerseits und den Andrücknasen andererseits. Nur wenn man zum Abreißen die Formularbahn im scharfen Winkel um die Abreißschiene herumführt, erfolgt während des Abreißvorganges ein stärkeres Andrücken der Andrücknasen an die Formularbahn. Versucht man dagegen, die Formularbahn dadurch abzureißen, daß man sie nur senkrecht in die Höhe zieht, dann erfolgt im Gegenteil entsprechend den kinematischen Verhältnissen in bezug auf die Lagerung der Klappe eher ein Entlasten der Formularbahn durch die Andrücknasen, so daß der gewünschte Effekt des Festhaltens der Formularbahnen während des Abreißvorganges nicht eintritt. Außerdem ist die _genannte Anordnung auch dadurch nachteilig, daß die Abreißvorrichtung immer nur bei einem bestimmten Formularweg wirksam werden kann, da sie nur an bestimmten Stellen des Umfanges der Druckunterlage in die Wirkungsstellung gebracht wird. Es können also immer nur Formulare von vorgeschriebener Länge abgerissen werden.In US-PS 1 25o 883 and in GB-PS 699 417 devices are described in which flaps arranged transversely to the printing pad are provided, which have a tear-off rail on one longitudinal edge, while the other longitudinal edges with retaining lugs or the like Paper. In both cases, these are swiveling flaps that have to be swiveled away for the paper insertion in a manner similar to the upper pressure rollers on a typewriter. In the case of GB-PS 699 417, the pivot point of the flap in the rear part of the rail frame lies outside the connecting line between the tear-off edge on the one hand and the pressing lugs on the other. Only when you tear off the form web at a sharp angle around the tear-off rail, is there a stronger pressure during the tear-off process the pressing lugs on the form web. If, on the other hand, you try to tear off the form web by only pulling it vertically upwards, on the contrary, depending on the kinematic conditions with regard to the mounting of the flap, the form web is relieved of pressure by the pressing lugs, so that the desired effect of holding on the form webs do not occur during the tear-off process. In addition, the arrangement mentioned is also disadvantageous in that the tear-off device can only ever be effective with a certain form path, since it is brought into the operative position only at certain points on the circumference of the printing document. Only forms of the prescribed length can be torn off.

In der US-PS 1 25o 883 ist die Abreißschiene zwischen zwei . Schwenkhebeln befestigt, die auf einer Achse hinter der Papierwalze gelagert sind. An den Schwenkhebeln sind vorne Zungen vorgesehen, die Anpreßrollen tragen, wie dies bei Schreibmaschinen für die oberen Andrückrollen üblich ist. Der Abstand der Schwenkhebel untereinander bestimmt die Breite des einzuführenden Formulares. Die Verstellbarkeit des Abstandes der Schwenkhebel untereinander ist begrenzt. Im übrigen ist es bei dieser Abreißvorrichtung notwendig, zum Einführen der Formularbahn die Andrückrollen mit der Abreißschiene wegzuschwenken, weil das saubere Einführen einer Mehrzahl von zu beschriftenden Formularen zwischen die in Anlage befindlichen Andrückrollen und die Schreibwalze nicht möglich ist.In US-PS 1 25o 883 the tear-off rail is between two. Swivel levers attached, which are mounted on an axis behind the paper roller. On the swivel levers, tongues are provided at the front which carry pressure rollers, as is customary in typewriters for the upper pressure rollers. The distance between the swivel levers determines the width of the form to be inserted. The adjustability of the distance between the swivel levers is limited. Moreover, it is necessary with this tear-off device to pivot the pressure rollers with the tear-off rail to insert the form web, because the clean insertion of a plurality of forms to be labeled between the pressure rollers in contact and the platen roller is not possible.

Demgegenüber hat es sich die Erfindung zur Aufgabe gemacht, eine Abreißvorrichtung für Formularbahnen zu schaffen, die das Einführen der Formularbahnen in keiner Weise behindert, die also zum Einführen der Formularbahnen nicht forgeschwenkt zu werden braucht und die für jede mögliche Formularbahnbreite Verwendung finden kann. Selbstverständlich soll die Abreißvorrichtung dabei auch so beschaffen-sein, daß sich die Formulare beim Abreißvorgang nicht relativ zu dem Druckwerk bzw. der Druckunterlage verschieben können.In contrast, it is the object of the invention to provide a tear-off device for form webs which does not hinder the insertion of the form webs in any way, which therefore does not need to be pivoted away for the insertion of the form webs and which can be used for any possible form web width. Of course, the tear-off device should also be designed in such a way that the forms are not relative to the printing unit during the tear-off process resp . can move the printing document.

Entsprechend der Aufgabenstellung geht die Erfindung aus von einer Abreißvorrichtung in Form einer Klappe, die an der ihrer Druckstelle abgekehrten Längskante mit einer Abreißschiene versehen ist und die an ihrer der Druckstelle zugewendeten Längskante mit einer Halteschiene oder Haltenasen für die Formularbahn während des Abreißvorganges versehen ist und die erfindungsgemäß dadurch gekennzeichnet ist, daß die Lager- und Schwenkpunkte der Klappe im Rahmen der Druckvorrichtung zwischen deren beiden Längskanten liegen, derart daß die Klappe sich durch den Abreißvorgang aus der Normalstellung, in der die Halteschiene bzw. -nasen unwirksam sind, in die Abreißstellung verschwenkt, in der die Halteschienen bzw. -nasen wirksam sind.According to the task, the invention is based on a tear-off device in the form of a flap which is provided with a tear-off rail at the longitudinal edge facing away from its pressure point and which is provided with a holding rail or retaining lugs for the form web during the tear-off process at its longitudinal edge facing the pressure point and which is characterized in that the bearing and pivot points of the flap in the context of the printing device between the two longitudinal edges, so that the flap pivots through the tearing process from the normal position in which the retaining rail or tabs are ineffective into the tear-off position in which the holding rails or lugs are effective.

Durch die erfindungsgemäße Ausbildung der Lagerung der Abreißvorrichtung ist es möglich, beliebig breite Formularbahnen einzuführen, ohne daß die Abreißvorrichtung weggeschwenkt werden muß, indem man einfach die Formularbahnen zwischen entsprechende Führungsschlitze hindurchsteckt. Im Abreißvorgang selbst erfolgt das Verschwenken der Abreißvorrichtung in der Weise, daß dann automatisch die in der Maschine verbleibenden Teile der Formularbahn festgeklemmt werden, so daß ein Verschieben relativ zum Druckwerk nicht möglich ist.By designing the storage of the tear-off device according to the invention, it is possible to introduce form webs of any width without the tear-off device having to be pivoted away by simply inserting the form webs between corresponding guide slots. In the tear-off process itself, the tearing-off device is pivoted in such a way that the parts of the form web remaining in the machine are then automatically clamped, so that it is not possible to move it relative to the printing unit.

Um das Verschieben der in der Druckvorrichtung verbleibenden Teile der Formularbahn noch besser zu sichern, ist entweder an dem die Formularbahn führenden Rahmenteil oder an der Halteschiene bzw. an den Haltenasen eine elastische Reibungsauflage als Widerlager vorgesehen, die sich beim Verschwenken der Formularbahn zusammenpreßt und dadurch das Halten der Formularbahn erleichtert. DasIn order to ensure even better the displacement of the parts of the form web remaining in the printing device, an elastic friction support is provided as an abutment either on the frame part guiding the form web or on the holding rail or on the holding lugs, which compresses when the form web is pivoted and thereby compresses it Keeping the form web relieved. The

Widerlager besteht auch vorzugsweise aus mehreren auf einer Führungsachse verschiebbaren Teilen, die auf die Formularbahnbreite eingestellt werden.Abutment also preferably consists of several parts which can be moved on a guide axis and which are adjusted to the width of the form web.

In den beiliegenden Zeichnungen ist ein Ausführungsbeispiel der Erfindung gezeigt. Dabei ist Figur 1 eine Darstellung der Abreißvorrichtung in der Ruhelage, Figur 2 eine Darstellung in der verschwenkten Arbeitslage'.In the accompanying drawings, an embodiment of the invention is shown. Figure 1 is a representation of the tear-off device in the rest position, Figure 2 is a representation in the pivoted working position '.

Man erkennt in Figur 2 den Druckkopf 1, der mit Drucknadeln oder anderen Druckelementen Buchstaben und Ziffern auf einer Druckunterlage 2 zum Abdruck bringt. Zwei Transportrollen 3 und .4, die von einem Schrittmotor angetrieben werden und die auf Achsen 5 und 6 oberhalb der Druckstelle 7 angeordnet sind, sorgen für den Transport der Formularbahn 8. Die Formularbahn wird zwischen zwei Führungsteilen 9 und 10 hindurch bewegt und mittels eines Trichters 11, der einerseits durch das Führungsteil 10, andererseits durch ein Rahmenteil 12 begrenzt wird, der Abreißvorrichtung 13 zugeführt. Die Führungsteile 9 und 10 können auch miteinander verbunden sein und die Seitenkantenführung für die Formularbahn 8 bilden. In diesem Falle sind die Teile auf der Achse 23 gemeinsam verschiebbar. Die Formularbahn 8 verläßt die Druckvorrichtung zwischen einem Gehäuseteil 14 und der Abreißvorrichtung 13.FIG. 2 shows the print head 1, which uses letters or other printing elements to print letters and numbers on a printing pad 2. Two transport rollers 3 and .4, which are driven by a stepper motor and which are arranged on axes 5 and 6 above the printing point 7, provide for the transport of the form web 8. The form web is moved between two guide parts 9 and 10 and by means of a funnel 11, which is delimited on the one hand by the guide part 10 and on the other hand by a frame part 12, the tear-off device 13. The guide parts 9 and 10 can also be connected to one another and form the side edge guide for the form web 8. In this case, the parts on the axis 23 can be moved together. The form web 8 leaves the printing device between a housing part 14 and the tear-off device 13.

Die Abreißvorrichtung 13 besteht aus einer Klappe 15, die einerseits eine als scharfe Kante ausgebildete Abreißschiene 16 besitzt, andererseits eine Halteschiene 17. Anstelle- der Halteschiene 17 könnten auch Haltenasen vorgesehen sein. Die Klappe 15 ist beidseits über Bolzen 18 mit Halteteilen 19 verbunden, die auf weiteren Bolzen 20 am Rahmenteil der Maschine - nicht gezeichnet - schwenkbar gelagert sind. Diese Art der Lagerung der Klappe 13 hat den Vorteil, daß beim Verschwenken der Klappe die Papierbahn sich nicht relativ zur Abreißschiene 16 verschwenkt. An dem Führungsteil 10 ist noch ein Widerlager 21 in Form einer elastischen Reibungsauflage angeordnet. Ferner ist an dem Rahmenteil 12 ein Dichtungsstreifen 22 vorgesehen, der der Geräuschdämmung dient. Das Führungsteil 10 kann mit dem Führungsteil 9 verbunden sein und seitlich auf einer Achse 23 verstellbar, um auf verschiedene Formularbahnbreiten eingestellt werden zu können. Anstelle eines sich über die ganze.Bahnbreite erstreckenden Widerlagers 21 sind zwei nur seitlich an der Formularbahn angreifende Widerlager günstiger, weil sich die Halteschiene 17 beim Andrücken unter Umständen durchbiegt und dann unter Umständen seitlich nicht mehr aufliegt.The tear-off device 13 consists of a flap 15 which on the one hand has a tear-off rail 16 designed as a sharp edge and on the other hand a holding rail 17. Instead of the holding rail 17, holding lugs could also be provided. The flap 15 is connected on both sides via bolts 18 to holding parts 19 which are pivotally mounted on further bolts 20 on the frame part of the machine, not shown. This type of mounting of the flap 13 has the advantage that when the flap is pivoted the paper web does not move relative to the tear-off slide ne 16 panned. An abutment 21 in the form of an elastic friction pad is also arranged on the guide part 10. Furthermore, a sealing strip 22 is provided on the frame part 12, which is used for noise insulation. The guide part 10 can be connected to the guide part 9 and laterally adjustable on an axis 23 in order to be able to be adjusted to different form web widths. Instead of an abutment 21 which extends over the entire width of the web, two abutments which only engage laterally on the form web are cheaper because the holding rail 17 may bend when pressed and then may no longer lie laterally.

Solange das Druckwerk druckt und ein Abreißen von Formularbahnen oder Teilen dieser Formularbahnen nicht gewünscht ist, befindet sich die Abreißvorrichtung 13 in der in Figur 1 gezeigten Stellung. Die Formularbahn 8 ist lose zwischen den Führungsteilen 9, 10 und dem Rahmen 12, 14 sowie der Abreißvorrichtung 13 hindurchgeführt. Soll eine Formularbahn, beispielsweise entlang der in diesen Formularbahnen normalerweise vorgesehenen Schwächungslinien, abgerissen werden, so. wird diese Formularbahn zwischen Daumen und Zeigefinger angefaßt und in Figur 2 nach rechts gezogen. Dabei verschwenkt sich die Klappe 15 und die Halteschiene 17 kommt in Eingriff mit der Formularbahn 8 und dem Widerlager 21. Der in der Maschine verbleibende Teil der Formularbahn 8 wird damit in der Druckvorrichtung zwischen den Transportrollen 3 und 4 festgelegt und kann nicht verzogen werden. Jetzt ist es möglich, indem man auf die eine Seitenkante der Formularbahn einen größeren Zug ausübt, den aus der Vorrichtung herausgetretenen Teil der Formularbahn entlang der Abreißschiene 16 abzureißen.As long as the printing unit prints and tearing off form webs or parts of these form webs is not desired, the tearing device 13 is in the position shown in FIG. 1. The form web 8 is loosely guided between the guide parts 9, 10 and the frame 12, 14 and the tear-off device 13. If a form web is to be torn off, for example along the weakening lines normally provided in these form webs, then. this form path is gripped between the thumb and index finger and pulled to the right in FIG. 2. The flap 15 pivots and the holding rail 17 comes into engagement with the form web 8 and the abutment 21. The part of the form web 8 remaining in the machine is thus fixed in the printing device between the transport rollers 3 and 4 and cannot be warped. It is now possible, by exerting a greater pull on one side edge of the form web, to tear off the part of the form web that has emerged from the device along the tear-off rail 16.
