Description

Die Erfindung betrifft eine auf den Schlitten eines Druckwerkes aufsetzbare Farbbandkassette mit einer Nachtränkvorrichtung für das Farbband, bei der die in einem Behälter einfüllbare Farbflüssigkeit einer benetzbaren Rolle zuführbar ist, über die das Farbband geleitet ist und die durch die Bewegung des Farbbandes gedreht wird.The invention relates to an ink ribbon cassette that can be placed on the carriage of a printing unit and has a soaking device for the ink ribbon, in which the ink liquid that can be filled into a container can be fed to a wettable roller over which the ink ribbon is guided and that is rotated by the movement of the ink ribbon.

Eine solche Farbbandkassette ist aus der EP-A-0 031 854 bekannt. Oberhalb der beiden mit Abstand voneinander angeordneten Farbbandspulen ist jeweils ein Farbspeicher angeordnet, so daß das Farbband in beiden Transportrichtungen des Farbbandes vor dem Druckbereich mit Farbflüssigkeit getränkt wird. Die Farbspeicher bestehen aus Filz und sind von dem übrigen Kassettengehäuse getrennt. Zwischen Spulenkörper und Schreibbereich ist das Farbband über eine Rolle mit harter Oberfläche geführt. Diese Rolle steht über einen abgewinkelten Teil mit dem zugeordneten Farbspeicher in Verbindung. Die Rolle wird von dem sich bewegenden Farbband gedreht, so daß die Rollenoberfläche ständig mit Farbflüssigkeit benetzt ist. Damit überschüssige Farbflüssigkeit über die Lager der Rollenachse nicht austritt, sind die radialen Begrenzungsflächen der Rolle mit ringförmigen Ausnehmungen als Fließsperre versehen.Such an ink ribbon cassette is known from EP-A-0 031 854. An ink reservoir is arranged above each of the two ink ribbon spools, which are spaced apart from one another, so that the ink ribbon is impregnated with ink liquid in both transport directions of the ink ribbon in front of the printing area. The color memories are made of felt and are separated from the rest of the cassette housing. The ribbon is guided over a roll with a hard surface between the bobbin and the writing area. This role is connected to the assigned color memory via an angled part. The roller is rotated by the moving ribbon so that the roller surface is constantly wetted with ink. The radial boundary surfaces of the roller are provided with ring-shaped recesses as a flow barrier so that excess ink does not escape through the bearings of the roller axis.

Nachteilig ist, daß auch bei nichtbewegtem Farbband Farbflüssigkeit durch ihr Eigengewicht zur Rolle gelangen kann. Aus diesem Grunde müssen besondere Vorkehrungen getroffen werden, um eine zu hohe Anreicherung der Farbspeicher mit Farbflüssigkeit zu vermeiden. Auch können solche Farbbandkassetten nicht zwischengelagert werden, da dann ebenfalls Farbflüssigkeit auslaufen kann.The disadvantage is that even when the ribbon is not moving, ink can roll due to its own weight. For this reason, special precautions must be taken to avoid over-enriching the ink reservoir with ink liquid. Also, such ribbon cartridges cannot be stored temporarily, since ink can also leak out.

Der Erfindung liegt die Aufgabe zugrunde, eine Farbbandkassette mit einer Nachtränkeinrichtung zu schaffen, bei der nur während der Bewegung des mit der Farbbandkassette versehenen Druckkopfes Farbflüssigkeit im Farbspeicher entnommen werden kann und die einfach im Aufbau ist..The invention has for its object to provide an ink ribbon cassette with a soaking device, in which ink can only be removed from the ink reservoir during the movement of the print head provided with the ink ribbon cassette and which is simple in construction.

Diese Aufgabe wird dadurch gelöst, daß der Behälter eine nach innen ragende, im wesentlichen quer zur Schlittenbewegung, liegende Schwelle besitzt, in deren obersten Teil ein Entnahmeröhrchen mündet, daß das andere Ende des Entnahmeröhrchens die Rolle berührt, daß die Rolle als saugfähige Rolle ausgebildet ist und daß der Flüssigkeitsspiegel im Ruhezustand unterhalb des obersten Teiles der Schwelle liegt.This object is achieved in that the container has an inwardly projecting, substantially transverse to the slide movement, lying threshold, in the uppermost part of a sampling tube that the other end of the sampling tube touches the role, that the role is designed as an absorbent role and that the liquid level is at rest below the uppermost part of the threshold.

Die Erfindung hat den Vorteil, daß Farbflüssigkeit nur dann der Schwammrolle und damit dem Farbband zugeführt wird, wenn der Flussigkeitsspiegel bewegt wird und über die Schwelle überschwappt. Dies wird bei einem relativ ruhig fortbewegten Druckkopf mindestens dann der Fall sein, wenn der Druckkopf seine Bewegungsrichtung ändert, also am Anfang und Ende einer Schreibzeile. Ob darüberhinaus auch noch während einer Bewegungsrichtung des Druckers Farbflüssigkeit über die Schwelle schwappt, hängt einerseits von den Bewegungserschütterungen und andererseits von der Höhe der Schwelle gegenüber dem Flüssigkeitsspiegel ab. In jedem Falle wird durch die Erfindung die Zufuhr der Farbflüssigkeit dosiert.The invention has the advantage that ink is only supplied to the sponge roller and thus to the ink ribbon when the liquid level is moved and spills over the threshold. With a relatively quietly moving printhead, this will be the case at least when the printhead changes its direction of movement, that is to say at the beginning and end of a writing line. Whether color liquid also spills over the threshold during a direction of movement of the printer depends on the one hand on the movement vibrations and on the other hand on the height of the threshold relative to the liquid level. In any case, the supply of the color liquid is metered by the invention.

Damit gewährleistet ist, daß auch Farbflüssigkeit in das Entnahmeröhrchen eindringt und nicht über dessen Öffnung hinweggespült wird, ist der Raum oberhalb der Schwelle und damit oberhalb der Öffnung des Entnahmeröhrchens verengt. Dies wird gemäß weiterer Ausbildung der Erfindung dadurch erreicht, daß innerhalb des Behälters zwei Hohlräume gebildet sind, deren Querschnitte sich verjüngen und deren sich berührende kleinste Querschnitte die Schwelle bilden und daß die beiden Hohlräume zusätzlich durch einen Luftausgleichkanal miteinander in Verbindung stehen.In order to ensure that colored liquid also penetrates into the sampling tube and is not washed away through its opening, the space above the threshold and thus above the opening of the sampling tube is narrowed. This is achieved according to a further embodiment of the invention in that two cavities are formed within the container, the cross sections of which taper and the contacting smallest cross sections form the threshold and that the two cavities are additionally connected to one another by an air equalization channel.

Anstelle dieser beiden sich allseits verjüngenden Hohlräume, durch die das Gehäuse nach Art einer Sanduhr ausgebildet ist, kann auch ein feststehendes kurzes Rohr verwendet werden, in dessen Innern die Schwele angeordnet ist oder das auf einer Schwelle selbst aufgesetzt ist. Das Rohr ist mit seiner Längsachse parailel und oberhalb des Flüssigkeitsspiegels im Gehäuse befestigt. In diesem Falle entfällt ein besonderer Luftausgleich innerhalb des Behälters. Zweckmäßig ist es, die innerhalb oder ausßerhalb des Rohres liegende Schwelle seitlich etwas hochzuziehen, damit die in Bewegung geratene Farbflüssigkeit zur Öffnung des Entnahmeröhrchens hingelenkt wird.Instead of these two cavities tapering on all sides, through which the housing is designed in the manner of an hourglass, a fixed short tube can also be used, inside which the sill is arranged or which is placed on a sill itself. The tube is parallel with its longitudinal axis and attached above the liquid level in the housing. In this case, there is no need for a special air balance inside the container. It is expedient to pull up the threshold lying inside or outside the tube somewhat to the side, so that the color liquid which has started to move is directed towards the opening of the sampling tube.

Die Erfindung wird im folgenden anhand einiger Ausführungsbeispiele näher erläutert. Es zeigen :

  • Figur 1 eine Farbbandkassette mit einer Nachtränkvorrichtung der Erfindung,
  • Figur 2 Details der Anordnung nach Figur 1,
  • Figur 3 ein weiteres Ausführungsbeispiel der Nachtränkvorrichtung und
  • Figur 4 ein anderes Ausführungsbeispiel der Nachtränkvorrichtung.
The invention is explained in more detail below with the aid of a few exemplary embodiments. Show it :
  • FIG. 1 shows an ink ribbon cassette with a night soaking device of the invention,
  • FIG. 2 details of the arrangement according to FIG. 1,
  • Figure 3 shows another embodiment of the night soaking device and
  • Figure 4 shows another embodiment of the night soaking device.

Die in Figur 1 in Draufsicht dargestellte Farbbandkassette 1 wird auf den Schlitten eines Druckwerkes in bekannter, nicht näher dargestellter Weise derart aufgesteckt, daß der nichtdargestellte Drucker in dem Raum 3 zu liegen kommt. Innerhalb der Farbbandkassette 1 ist ein endloses Farbband 2 angeordnet, das durch den Antrieb und die Andruckrolle 4, 5 in Pfeilrichtung bewegt wird. Dabei wird das Farbband 2 um die Umlenkrolle 6 und die Gegenrolle 7 gezogen.The ribbon cassette 1 shown in top view in FIG. 1 is attached to the carriage of a printing unit in a known, not shown manner such that the printer, not shown, comes to rest in room 3. An endless ink ribbon 2 is arranged inside the ink ribbon cassette 1 and is moved in the direction of the arrow by the drive and the pressure roller 4, 5. The ink ribbon 2 is pulled around the deflection roller 6 and the counter roller 7.

Auf dem hinteren Ende der Farbbandkassette 1 ist die Nachtränkvorrichtung befestigt. Diese besteht aus dem Behälter 8 und der Rolle 12. Die Rolle 12 ist in der Farbbandkassette 1 gelagert und arbeitet mit der Gegenrolle 7 zusammen. Der Behälter 8 enthält in seinem Inneren zwei Hohlräume 9 und 10. deren Querschnitte sich verjüngen und die mit ihren kleinsten Querschnitten gegenüberliegen.On the rear end of the ribbon cassette 1, the night soak is attached. This consists of the container 8 and the roller 12. The roller 12 is stored in the ink ribbon cassette 1 and works together with the counter roller 7. The container 8 contains two cavities 9 and 10 in its interior, the cross sections of which taper and which with their smallest cross sections counter lie.

In diesem Bereich bilden sie eine Schwelle 16, in die ein Entnahmeröhrchen 13 mündet. Beide Hohlräume 9 und 10 können flaschenähnlich oder nach Art einer Hohlpyramide oder eines Hohlkegels ausgebildet sein. Wesentlich ist, daß an der verjüngten Stelle eine Schwelle oder Engsteile vorhanden ist. Zweckmäßig wird ein Durchmesser dieser Engstelle von 1,5 mm und eine Länge von etwa 2 mm gewählt. Damit ausreichend Farbflüssigkeit 11 in die Hohlräume 9 und 10 eingefüllt werden kann, wird die Unterkante dieser Schwelle 16 vom Boden der Hohlräume 9 und 10 ausgesehen etwa in die Mitte des Behälters 8 gelegt, wenn dieser Behälter 8 einen Durchmesser oder eine Seitenkante von 11 mm hat. Der Behälter 8 wird zweckmäßig aus zwei Teilen hergestellt, aus einem oberen und einem unteren Behälterteil 14 und 15. Nach Abschrauben der Einfüllschraube 22 kann durch die dann entstehende Öffnung Tintenflüssigkeit 11 nachgefüllt bzw. eingefüllt werden. Dabei ist darauf zu achten, daß der Flüssigkeitsspiegel nicht über die Oberkante der Schwelle 16 reicht. Beide Hohlräume 9 und 10 stehen zusätzlich über einen Luftausgleichkanal 21 miteinander in Verbindung.In this area they form a threshold 16 into which a sampling tube 13 opens. Both cavities 9 and 10 can be bottle-like or in the form of a hollow pyramid or a hollow cone. It is essential that there is a threshold or narrow parts at the tapered point. A diameter of this constriction of 1.5 mm and a length of approximately 2 mm are expediently selected. So that sufficient color liquid 11 can be filled into the cavities 9 and 10, the lower edge of this threshold 16, viewed from the bottom of the cavities 9 and 10, is placed approximately in the middle of the container 8 if this container 8 has a diameter or a side edge of 11 mm . The container 8 is expediently produced from two parts, from an upper and a lower container part 14 and 15. After unscrewing the filler screw 22, ink liquid 11 can be refilled or filled through the opening that then arises. It should be ensured that the liquid level does not reach over the upper edge of the threshold 16. Both cavities 9 and 10 are additionally connected to one another via an air compensation duct 21.

Beim Drucken wird der Druckkopf und die Farbbandkassette in Pfeilrichtung P hin und herbewegt. Bei der Richtungsumkehr in den Endpunkten der Bewegung tritt ständig eine Beschleunigung auf. Dadurch schnappt die Farbflüssigkeit 11 über die Schwelle 16 hin und her. Der in dieser Engstelle entstehende Druck drückt dabei auch einen kleinen Teil der Farbflüssigkeit in das Entnahmeröhrchen 13, von wo aus die Flüssigkeit zur Schwammrolle 12 gelangt.During printing, the print head and the ribbon cassette are moved back and forth in the direction of the arrow P. When the direction is reversed at the end points of the movement, acceleration occurs continuously. As a result, the color liquid 11 snaps back and forth across the threshold 16. The pressure arising in this constriction also presses a small part of the paint liquid into the removal tube 13, from where the liquid reaches the sponge roller 12.

Dazu endet das Entnahmeröhrchen 13 kurz über der oberen seitlichen Begrenzungsfläche der Schwammrolle 12. Beim Überschwappen der Farbflüssigkeit über die Schwelle 16 wird somit ein kleiner Teil der Farbe auf die Schwammrolle 12 getropft, die diese Farbe auf das Farbband 2 überträgt. Die Größe der Engstelle und der Durchmesser des Entnahmeröhrchens 13 hängen von der Art der verwendeten Tinte und von der gewünschten Schwärzung des Abdruckes ab.For this purpose, the removal tube 13 ends shortly above the upper lateral boundary surface of the sponge roller 12. When the ink liquid spills over the threshold 16, a small part of the paint is thus dripped onto the sponge roller 12, which transfers this ink to the ink ribbon 2. The size of the constriction and the diameter of the withdrawal tube 13 depend on the type of ink used and on the desired blackening of the impression.

Wird der Drucker stillgesetzt, so treten keine Beschleunigungen mehr auf und der Zufluß an Farbflüssigkeit in das Entnahmeröhrchen 13 versiegt. Auch die Lagerung der Farbbandkassette in irgendeiner beliebigen Achse hat keinen Ausfluß an Farbflüssigkeit zur Folge. Lediglich ruckartige Bewegungen in Längsrichtung des Behälters 8 und in waagerechter Lage können zur Abgabe von Farbflüssigkeit führen.If the printer is shut down, accelerations no longer occur and the inflow of color liquid in the withdrawal tube 13 dries up. The storage of the ribbon cassette in any axis does not result in an outflow of ink. Only jerky movements in the longitudinal direction of the container 8 and in a horizontal position can lead to the release of color liquid.

In den Figuren 3 und 4 sind zwei weitere Ausführungsbeispiele des Behälters 8 nach Figur 1 dargestellt. Bei dem Ausführungsbeispiel nach figur 3 ist die Schwelle 16 durch den Scheitelpunkt einer nach beiden Seiten abfallenden Auflaufschräge 17 gebildet. Auf diesem Scheitelpunkt ist ein Rohr 18 befestigt, dessen Längsrichtung mit der Längsrichtung des Behälters 8 zusammenfällt oder dazu parallel verläuft. Um bei einer Bewegungsumkehr möglichst viel Farbflüssigkeit 11 durch das Rohr 18 gelangen zu lassen, wird der Scheitel der Ablaufschräge 17 seitlich des Rohres 18 angehoben.FIGS. 3 and 4 show two further exemplary embodiments of the container 8 according to FIG. 1. In the exemplary embodiment according to FIG. 3, the threshold 16 is formed by the apex of a run-up slope 17 falling to both sides. At this apex, a tube 18 is fastened, the longitudinal direction of which coincides with the longitudinal direction of the container 8 or runs parallel to it. In order to allow as much color liquid 11 to pass through the tube 18 when the movement is reversed, the apex of the run-off slope 17 is raised to the side of the tube 18.

Beim Ausführungsbeispiel nach Figur 4 ist innerhalb des Behälters 8 ein Rohr 19 befestigt, in dessen Inneren die Schwelle 20 angeordnet ist. Damit möglichst Farbflüssigkeit durch das Rohr 19 gelangt, ist es zweckmäßig, daß das Rohr 19 annähernd den inneren Querschnitt des Behälters 8 bedeckt. Aus dem gleichen Grunde ist es zweckmäßig, die Schwelle 20 in Längsrichtung des Behälters 8 gesehen, seitlich erhöht auszubilden.In the exemplary embodiment according to FIG. 4, a tube 19 is fastened inside the container 8, in the interior of which the threshold 20 is arranged. So that the most possible color liquid passes through the tube 19, it is expedient that the tube 19 covers approximately the inner cross section of the container 8. For the same reason, it is expedient to design the threshold 20 laterally elevated in the longitudinal direction of the container 8.
