Description

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

Vorrichtungen der eingangs genannten Art sind allgemein bekannt. So wird in der europäischen Patentanmeldung 0054327 eine Ablagevorrichtung für Datenträger beschrieben, bei der die Datenträger einem Ablagebehälter durch Zuführrollen von unten zugeführt werden. Dabei wird der einzelne Datenträger mit seiner Unterkante über eine dieser Rollen umgelenkt. Die Ablagevorrichtung enthält ein abnehmbares Ablagefach, das bedarfsweise in eine hintere und nach Drehung um 180° in eine vordere Stellung eingesteckt werden kann. Die hierzu vorgesehenen Aufstecklager sind symmetrisch zu der gemeinsamen Tangentialebene der Zuführrollen angeordnet. Zur einwandfreien Umlenkung der Datenträger in die durch die Stellung des Ablagefaches bestimmte Richtung, besitzt die Ablegevorrichtung eine Hebelanordnung, die durch das Ablagefach in die vorbestimmte Lage verschwenkt wird.Devices of the type mentioned are generally known. For example, a storage device for data carriers is described in European patent application 0054327, in which the data carriers are fed to a storage container from below by feed rollers. The lower edge of the individual data carrier is redirected over one of these rollers. The storage device contains a removable storage compartment which, if necessary, can be inserted into a rear position and, after rotation by 180 °, into a front position. The plug-in bearings provided for this purpose are arranged symmetrically to the common tangential plane of the feed rollers. For the correct deflection of the data carrier in the direction determined by the position of the storage compartment, the storage device has a lever arrangement which is pivoted into the predetermined position by the storage compartment.

Es ist weiters aus dem IBM, Technical Disclosure Bulletin, Vol. 23, Nr. 7b, Dez. 1980, Seiten 3077/3078 eine automatische Ablageeinrichtung bekannt, bei der die zu beschreibenden Einzelblätter einem Druckbereich zugeführt und dort zunächst vollständig beschrieben werden. Nach dem Verlassen des Druckbereiches werden sie von Zuführungsrollen erfaßt, die das Papierblatt beschleunigen, so daß es sich nach Verlassen der Papiertransportrollen hinter einer Ablageschwelle des Papierablagebehälters absetzt. Der von den Papiertransportrollen getrennte Ablagebehälter kann entsprechend der gewünschten Ablagerichtung verschwenkt werden.An automatic filing device is also known from IBM, Technical Disclosure Bulletin, Vol. 23, No. 7b, Dec. 1980, pages 3077/3078, in which the single sheets to be written are fed to a printing area and are initially described there completely. After leaving the printing area, they are gripped by feed rollers which accelerate the paper sheet so that after leaving the paper transport rollers it settles behind a storage threshold of the paper storage container. The storage container, which is separate from the paper transport rollers, can be swiveled according to the desired storage direction.

Durch die Anordnung von stationären Papiertransportrollen mit festem Abstand wird das Einführen des abzulegenden Einzelblattes erschwert. So müßen beim eigentlichen Druckvorgang die Transportrollen mitbewegt werden, was zu einem Verspannen zwischen Transportrollen und Schreibwalze führen kann und damit zu schlechter Druckqualität. Dies insbesondere dann, wenn das Druckbild noch feucht ist, wenn es in den Bereich der Papiertransportrollen gerät.The arrangement of stationary paper transport rollers at a fixed distance makes it difficult to insert the single sheet to be deposited. The transport rollers have to be moved during the actual printing process, which can lead to tension between the transport rollers and the platen roller and thus to poor print quality. This is especially true when the printed image is still damp when it gets into the area of the paper transport rollers.

Aufgabe der Erfindung ist es, für Druckeinrichtungen der eingangs genannten Art eine funktionssichere Ablagevorrichtung für blattförmige Aufzeichnungsträger bereitzustellen, mit der die blattförmigen Aufzeichnungsträger leicht und sicher in den Ablagebehälter transportiert und dort abgelegt werden können.The object of the invention is to provide a functionally reliable storage device for sheet-like recording media for printing devices of the type mentioned at the outset, with which the sheet-like recording media can be transported easily and safely into the storage container and stored there.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art gemäß dem kennzeichnenden Teil des ersten Patentanspruches gelöst.This object is achieved in a device of the type mentioned at the outset according to the characterizing part of the first claim.

Weitere vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Dadurch, daß von den nebeneinander liegenden Transportrollen die eine fest gelagert ist, während die daneben angeordnete Nachbartransportrolle von dieser über eine Schwenkeinrichtung steuerbar wegschwenkbar gelagert ist, ist es möglich, während des Druckvorganges die Nachbartransportrolle abzuschwenken um so das Einzelblatt leichter in den Ablagebehälter einschieben zu können. Damit ergibt sich eine breite Einführöffnung. Erst bei der eigentlichen Ablage nach Beendigung des Druckvorganges werden die Transportrollen zusammengeführt und die Transportrollen heben dann das Einzelblatt in den Ablagebehälter.The fact that one of the transport rollers lying next to one another is firmly supported, while the adjacent transport roller arranged next to it can be pivoted away by means of a pivoting device, it is possible to pivot the neighboring transport roller during the printing process so that the single sheet can be more easily pushed into the storage container . This results in a wide insertion opening. The transport rollers are only brought together during the actual storage after the printing process has ended and the transport rollers then lift the single sheet into the storage container.

In einer hier nicht im einzelnen dargestellten Druckeinrichtung, z. B. einem Datendrucker wird in üblicher Weise ein Schreibkopf 1 im Schreibbetrieb zeilenweise entlang eines über eine Schreibwalze 2 gespannten Aufzeichnungsträger 3 bewegt. Als Aufzeichnungsträger werden dabei Einzelblätter verwendet, die mit Hilfe der motorisch angetriebenen Schreibwalze 2 von hinten nach vorn durch eine Papierführung 4 entsprechend dem Fortgang des Schreibbetriebs transportiert werden. Oberhalb der Schreibwalze 2 ist ein Ablagebehälter 5 angeordnet, der dazu dient, die bedruckten Einzelblätter aufzunehmen und innerhalb des Behälters abzustapeln. Zu diesem Zweck sind im Ausgabebereich der Schreibwalze oberhalb der Schreibwalze und mit dem Ablagebehälter verbunden, zwei nebeneinander angeordnete Transportrollen 6/1, 6/2 vorgesehen, wobei die linke Transportrolle über z. B. einen Riemen 7 mit der Antriebseinrichtung der Schreibwalze 2 gekoppelt ist und über diese angetrieben ist. Der Ablagebehälter 5 stützt sich mit seinem Gehäuse 8 auf der Lagerachse 9 der linken angetriebenen Transportrolle ab und kann um diese Lagerachse 9 verschwenkt werden. Die Transportrollen 6 sind jeweils paarweise angeordnet und sind, aus der Schnittdarstellung nicht ersichtlich, jeweils an den Rändern des Ablagebehälters gelagert, so daß die Einzelblätter ohne Faltenwurf transportiert werden können.In a printing device, not shown here in detail, for. B. a data printer, a write head 1 is moved in the write mode line by line along a tensioned over a platen 2 recording medium 3. Single sheets are used as recording media, which are transported with the help of the motor-driven platen roller 2 from back to front through a paper guide 4 in accordance with the progress of the writing operation. Above the platen roller 2 there is a storage container 5 which serves to receive the printed single sheets and to stack them inside the container. For this purpose, two transport rollers 6/1, 6/2 arranged next to one another are provided in the output region of the platen roller above the platen roller and connected to the storage container. B. a belt 7 is coupled to the drive device of the platen roller 2 and is driven by this. The storage container 5 is supported with its housing 8 on the bearing axis 9 of the left driven transport roller and can be pivoted about this bearing axis 9. The transport rollers 6 are each arranged in pairs and, not visible from the sectional view, are each mounted on the edges of the storage container, so that the individual sheets can be transported without folds.

Der Ablagebehälter ist nun so ausgestaltet, daß die in den Ablagebehälter 5 transportierten Einzelblätter sowohl in steigender als auch in fallender Ablagereihenfolge abgestapelt werden können. Zu diesem Zwecke ist die rechte Transportrolle 6/2 im Transportbehälter um einen Drehpunkt 10 schwenkbar gelagert. Zugleich wird damit auch das Einführen der Einzelblätter in den Behälter erleichtert. Die rechte Transportrolle 6/2 stützt sich dabei über ihren Schwenkarm 11 an einer Feder 12 ab, die über eine Klinkeneinrichtung 13 mit einem die Klinkeneinrichtung betätigenden Drehmagneten 14 in Verbindung steht.The storage container is now designed so that the single sheets transported in the storage container 5 can be stacked both in increasing and in falling order. For this purpose, the right transport roller 6/2 is pivotally mounted in the transport container about a pivot point 10. At the same time, the insertion of the single sheets into the container is also facilitated. The right transport roller 6/2 is supported via its swivel arm 11 on a spring 12 which is connected via a latch device 13 to a rotary magnet 14 actuating the latch device.

Im Ablagebehälter 5 sind jeweils an den vorderen und hinteren Ablageflächen drehbar gelagerte Klappen 15 vorgesehen, die zur Unterstützung der Papierablage dienen.In the storage container 5, rotatably mounted flaps 15 are provided on the front and rear storage surfaces, which serve to support the paper storage.

Die Funktion der Ablagevorrichtung für Einzelblätter ist dabei wie folgt. Zur Ablage der Einzelblätter in steigender Reihenfolge, d. h. in einer Reihenfolge bei der das zuerst beschriebene Papier nach der Entnahme des Papierstapels aus dem Ablagebehälter an unterster Stelle zu liegen kommt, wird der Ablagebehälter entsprechend der Darstellung in Fig. 1 und 2 um die Lagerachse 9 nach hinten verschwenkt. Ein Einzelblatt 3 wird von hinten über die Schreibwalze 2 zur Schreibstelle gegenüber dem Schreibkopf 1 transportiert. Um das Einzelblatt leichter in den Ablagebehälter 5 einschieben zu können, sind die Transportrollen 6/1 und 6/2 über die Klinkeneinrichtung 13 auseinandergeschwenkt. so daß sich eine breite Einführöffnung 16 ergibt. Das Einzelblatt wird nun entsprechend der Drehung der Schreibwalze nach oben in den Ablagebehälter 5 eingeschoben und stößt dabei mit seiner Oberkante an die nach links verschwenkte rechte Klappe 15/2 an und wird von dieser umgelenkt. Die Klappen sind dabei so gelagert, daß sie infolge ihrer Schwerkraft durch einfaches Umschwenken des Ablagebehälters 5 in die verschiedenen entsprechend Fig. 1 und 3 dargestellten Positionen gelangt.The function of the storage device for single sheets is as follows. For storing the single sheets in increasing order, i.e. H. In a sequence in which the paper described first comes to lie at the lowest point after the paper stack has been removed from the storage container, the storage container is pivoted backward about the bearing axis 9 as shown in FIGS. 1 and 2. A single sheet 3 is transported from behind via the platen roller 2 to the writing point opposite the writing head 1. In order to be able to push the single sheet more easily into the storage container 5, the transport rollers 6/1 and 6/2 are pivoted apart via the latch device 13. so that there is a wide insertion opening 16. The single sheet is now pushed upwards into the storage container 5 in accordance with the rotation of the platen roller and in doing so abuts with its upper edge on the right flap 15/2 pivoted to the left and is deflected by the latter. The flaps are mounted so that, due to their gravity, they move into the various positions shown in FIGS. 1 and 3 by simply pivoting the storage container 5.

Die Klinkeneinrichtung 13, die die Transportrollen 6 verschwenkt, wird über den Drehmagneten 14 betätigt, der wiederum über einen Schalter 17 aus einer Gleichspannungsquelle 18 in Abhängigkeit von der gewünschten Drehrichtung mit entsprechend gepoltem Gleichstrom 18 versorgt wird. Der Schalter wird dabei von der Druckerelektronik über den Druckkopf 1 so gesteuert, daß sich die Transportrollen, wie bereits beschrieben, beim Schreibvorgang im geöffneten Zustand befinden. Nach Beendigung des Druckvorganges wird zur eigentlichen Ablage des Einzelblattes 3 in dem Ablagebehälter 5 über den Schalter 17 der Drehmagnet 14 so angesteuert, daß sich die rechte Transportrolle 6/2 unter der Wirkung der Feder 12 an die linke Transportrolle 6/1 anlegt und dabei Druck auf den zwischen den Transportrollen eingeführten Aufzeichnungsträger ausübt, so daß durch die von der linken Transportrolle 6/1 ausgehende Reibkraft das Einzelblatt 3 in den Ablagebehälter 5 eingeschoben werden kann.The pawl device 13, which pivots the transport rollers 6, is actuated via the rotary magnet 14, which in turn is supplied with a correspondingly polarized direct current 18 via a switch 17 from a direct voltage source 18 depending on the desired direction of rotation. The switch is controlled by the printer electronics via the print head 1 so that the transport rollers, as already described, are in the open state during the writing process. After completion of the printing process for the actual storage of the single sheet 3 in the storage container 5 via the switch 17, the rotary magnet 14 is controlled so that the right transport roller 6/2 engages under the action of the spring 12 on the left transport roller 6/1 and thereby pressure exerts on the record carrier inserted between the transport rollers, so that the single sheet 3 can be inserted into the storage container 5 by the frictional force emanating from the left transport roller 6/1.

Entsprechend der Schwenklage des Ablagebehälters 5 und bei der gewünschten Ablage in steigender Reihenfolge wird das Einzelblatt, wie in der Fig. 2 dargestellt, nach links abgelegt. Diese Ablage wird in erster Linie durch die Drehrichtung der linken Transportrolle 6/1 bewirkt. Eine zusätzliche Unterstützung erfolgt noch durch die nach links geschwenkte rechte Schwenkklappe 15/2.In accordance with the pivoting position of the storage container 5 and with the desired storage in increasing order, the single sheet is deposited to the left, as shown in FIG. 2. This storage is primarily caused by the direction of rotation of the left transport roller 6/1. Additional support is provided by the right swivel flap 15/2, which is swiveled to the left.

Soll entsprechend Fig. 3 und 4 eine Ablage der Einzelblätter in fallender Reihenfolge erfolgen, so wird der Ablagebehälter nach rechts verschwenkt. In diesem Falle erfolgt eine Ablage der Einzelblätter derart, daß das zuerst beschriebene Blatt mit der Schriftseite auf die rechte Ablagefläche gerichtet auf der rechten Behälterwand des Ablagebehälters 5 abgelegt wird. Das zuletzt beschriebene Einzelblatt befindet sich deshalb nach der Entnahme des Einzelblattstapels aus der Ablage an der Unterseite des Stapels. Daraus ergibt sich, vom unteren Blatt aus betrachtet, eine fallende Reihenfolge der abgestapelten Einzelblätter.3 and 4, if the individual sheets are to be deposited in a descending order, the storage container is pivoted to the right. In this case, the individual sheets are deposited in such a way that the sheet described first is placed on the right-hand wall of the storage container 5 with the writing side facing the right-hand storage surface. The cut sheet described last is therefore after removing the cut sheet stack from the tray on the underside of the stack. From the bottom sheet, this results in a descending order of the stacked single sheets.

Die Ausbildung der Abstapeleinrichtung läßt sich im einzelnen noch beliebig variieren. So können die Klappen 15 z. B. als eine einzige im Zentrum schwenkbare Klappe ausgebildet sein, die z. B. über Magneten verschwenkt wird. Anstelle der Klinkeneinrichtung, die die rechte Transportrolle steuert, ist es möglich, ebenfalls direkt Elektromagneten oder ähnliche Antriebseinrichtungen zu verwenden. Selbstverständlich ist es auch möglich, die Transportrollen 6 unabhängig von dem Antrieb der Schreibwalze 2 anzutreiben.The design of the stacking device can be varied as desired in detail. So the flaps 15 z. B. be formed as a single pivotable flap in the center, the z. B. is pivoted over magnets. Instead of the pawl device that controls the right-hand transport roller, it is also possible to use electromagnets or similar drive devices directly. Of course, it is also possible to drive the transport rollers 6 independently of the drive of the platen roller 2.
