Abstract
Eine derartige Farbbandeinrichtung für Drucker, insbesondere für Matrixdrucker, weist die Farbbandkassette (1) stützende, am Druckerrahmen (14) vorgesehene, oben offene Lager (15) paarweise auf, in die am Farbbandgehäuse (10) befestigte Lagerzapfen (11b) ebenfalls paarweise eingreifen, die an den Breitseiten (3,4) des auswechselbaren Farbbandgehäuses (10) angeordnet sind und das Farbbandgehäuse (10) im Bereich des Schreibwiderlagers weist stützende Nockenkurven (17) auf, die eine Hubbewegung mittels eines auf der Nockenwelle (18) angeordneten Antriebsomotors übertragen.Such an ink ribbon device for printers, in particular for matrix printers, has the ink ribbon cassette (1) supporting, on the printer frame (14), open top bearings (15) in pairs, in which bearing pins (11b) attached to the ink ribbon housing (10) also engage in pairs, which are arranged on the broad sides (3, 4) of the exchangeable ribbon housing (10) and the ribbon housing (10) in the area of the writing abutment has supporting cam curves (17) which transmit a lifting movement by means of a drive motor arranged on the camshaft (18).
Um die Kosten für unterschiedliche Spritzwerkzeuge bei der Herstellung der Farbbandgehäuse (10) einzusparen bzw. die Lagerhaltung für derartige Farbbandgehäuse (10) zu vereinfachen, wird vorgeschlagen, daß das Farbbandgehäuse (10) für Einfarben-Farbbänder (7) und für Mehrfarben-Farbbänder (8) einheitlich mit zwei Paaren von Lagerzapfen (11a,11b; 12a,12b) versehen ist und daß für in Betriebslage vorhandene Nockenkurven (17) gegenüberliegend an den Breitseiten (3,4) des Farbbandgehäuses (10) jeweils ein ebener Auflagervorsprung (13a,13b) vorgesehen ist.

Description
Die Erfindung betrifft eine Farbbandeinrichtung für Drucker, insbesondere für Matrixdrucker, mit die Farbbandkassette stützenden, am Druckerrahmen vorgesehenen, oben offenen Lagern, in die am Farbbandgehäuse befestigte Lagerzapfen eingreifen, die an den Breitseiten des auswechselbaren Farbbandgehäuses angeordnet sind und mit das Farbbandgehäuse im Bereich des Schreibwiderlagers stützenden Nockenkurven, die eine Hubbewegung mittels eines auf der Nockenwelle angeordenten Antriebsmotors übertragen.The invention relates to a ribbon device for printers, in particular for matrix printers, with the ribbon cassette-supporting bearings provided on the printer frame and open at the top, into which bearing journals attached to the ribbon housing engage, which are arranged on the broad sides of the exchangeable ribbon housing and with the ribbon housing in the area of the writing abutment supporting cam curves that transmit a lifting movement by means of a drive motor arranged on the camshaft.
Die Farbbandkassettengehäuse enthalten Endlosfarbbänder, die durch einen von außen ankuppelbaren Antrieb mittels im Innern angeordneter Rollenpaare angetrieben werden. Das Farbband verläßt durch einen Gehäuseausgang in der Nähe an einem Ende des Schreibwiderlagers einen Gehäusevorsprung, wird durch den hin- und hergehenden Druckkopf entlang an einem Druckwiderlager geführt und läuft durch einen Gehäuseeingang in der Nähe des anderen Endes am Schreibwiderlager in einen gegenüberliegenden Gehäusevorsprung. Das Endlosfarbband wird auf diese Art im Kreislauf geführt. Das Farbbandgehäuse ist auswechselbar und ruht in Lagern, die oben offen sind.The ribbon cassette housings contain endless color ribbons which are driven by an externally connectable drive by means of pairs of rollers arranged inside. The ribbon exits a housing protrusion through a housing exit nearby at one end of the platen, is passed through the reciprocating printhead along a platen and runs through a housing input near the other end on the platen into an opposite housing protrusion. The endless ribbon is circulated in this way. The ribbon housing is interchangeable and rests in bearings that are open at the top.
Eine bekannte Lösung (EP 0 158 963), die ein mehrfarbiges Farbband betrifft, weist eine solche Einrichtung auf. Das Farbbandgehäuse ist mittels eines fluchtenden Zapfenpaares in Lagern des Druckerrahmens schwenkbar gehalten, so daß die nebeneinanderliegenden Spuren der einzelnen Farben des Mehrfarben-Farbbandes durch eine Nickbewegung des Farbbandgehäuses vor der Druckstelle des Schreibwiderlagers auf- und abbewegt werden kann. Diese Nickbewegung wird durch eine Kurven steuerung einer Kurvennocke erzeugt, die mittels eines elektrischen Drehmotors angetrieben ist. Die bekannte Lösung ist jedoch auf mehrfarbige Farbbänder beschränkt. Für einfarbige Farbbänder muß daher ein umgestaltetes Farbbandgehäuse geschaffen werden, so daß zwei unterschiedliche Farbbandgehäuse erforderlich werden. Bei der Herstellung der Farbbandkassetten ist dieser Umstand zeitraubend, aufwendig und damit kostspielig. Das System mit zwei unterschiedlichen Farbbandgehäusen erhöht z.B. die Lagerhaltung und damit die Lagerkosten.A known solution (EP 0 158 963), which relates to a multicolored ink ribbon, has such a device. The ribbon housing is pivotally held in bearings of the printer frame by means of an aligned pair of pins, so that the adjacent traces of the individual colors of the multicolor ink ribbon can be moved up and down by a pitching movement of the ribbon housing in front of the printing point of the platen. This pitching motion is a curve Control of a cam cam is generated, which is driven by an electric rotary motor. However, the known solution is limited to multi-colored ribbons. A redesigned ribbon housing must therefore be created for monochrome ribbons, so that two different ribbon housings are required. This is time-consuming, time-consuming and therefore costly to manufacture the ribbon cassettes. The system with two different ribbon housings increases, for example, the storage and thus the storage costs.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein einziges Farbbandgehäuse vorzuschlagen, das sowohl für Einfarben- als auch für Mehrfarben-Farbbänder geeignet ist. Es soll daher bei der Fertigung der Farbbandgehäuse nur noch ein einheitliches Farbbandgehäuse mit unterschiedlichen Farbbändern bestückt werden.The invention is therefore based on the object of proposing a single ribbon housing which is suitable for both single-color and multicolor ribbons. For this reason, only a uniform ribbon housing should be equipped with different ribbons during the production of the ribbon housing.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Farbbandgehäuse für Einfarben-Farbbänder und für Mehrfarbenfarbbänder einheitlich mit zwei Paaren von Lagerzapfen versehen ist und daß für in Betriebslage vorhandene Nockenkurven gegenüberliegend an den Breitseiten des Farbbandgehäuses jeweils ein ebener Auflagervorsprung vorgesehen ist. Dieses System erfordert in der Fertigung der Farbbandgehäuse nur ein einziges Spritzwerkzeug. Die in dem Spritzwerkzeug hergestellten Farbbandgehäuse werden entweder mit einem Einfarben-Farbband oder mit einem Mehrfarben-Farbband gefüllt. Bei Einbau der Farbbandkassette kann der Drucker selbst für ein Einfarben- oder ein Mehrfarben-System ausgerüstet sein. In beiden Fällen ist das Farbbandgehäuse gleich bzw. für den jeweiligen Anwendungsfall bereits vorbereitet. Die entsprechenden Bauteile am Drucker sind ebenfalls leicht in der Fertigung und in der Montage umzustellen. Es wird lediglich anstelle einer Kurvennockensteuerung ein zweites Lager vorgesehen, das eine starre Anordnung des Farbbandgehäuses gestattet. Es ergeben sich daher folgende vorteilhafte Gestaltungen der Farbbandeinrichtung:
Nach einer ersten Gestaltungsweise ist vorgesehen, daß für eine Farbbandkassette mit einem Einfarben-Farbband am Druckerrahmen den beiden Paaren von Lagerzapfen gegenüberliegend, jeweils oben offene Lagerpaare vorgesehen sind.The object is achieved according to the invention in that the ribbon housing for single-color ribbons and for multicolor ribbons is provided with two pairs of bearing journals and that a flat support projection is provided opposite each other on the broad sides of the ribbon housing for cam curves present in the operating position. This system requires only a single injection tool in the production of the ribbon housing. The ribbon housings produced in the injection mold are filled either with a single-color ribbon or with a multicolor ribbon. When installing the ribbon cassette, the printer itself can be equipped for a single-color or a multi-color system. In both cases the ribbon housing is the same or already prepared for the respective application. The corresponding components on the printer are also easy to convert in production and assembly. Instead of a cam cam control, a second bearing is only provided, which allows a rigid arrangement of the ribbon housing. The following advantageous configurations of the result Ribbon setup:
According to a first design, it is provided that for an ink ribbon cassette with a single-color ink ribbon on the printer frame opposite the two pairs of trunnions, bearing pairs open at the top are provided.
Nach einer zweiten Gestaltungsweise wird vorgeschlagen, daß für eine Farbbandkassette mit einem Mehrfarben-Farbband am Druckerrahmen den beiden Paaren von Lagerzapfen gegenüberliegend, nur ein Paar fluchtender, oben offener Lagerpaare vorgesehen ist.According to a second design, it is proposed that only a pair of aligned, open-top bearing pairs is provided for a ribbon cassette with a multicolor ribbon on the printer frame opposite the two pairs of bearing journals.

The broad side (3) ends with a housing outlet (6) from which a single-color ribbon (7) or a multicolor ribbon (8) emerges and through a housing entrance (9) back into the other broad side (4), so that the ribbon is guided in a circle.
Der Antrieb des jeweiligen Farbbandes besteht aus im Inneren des Farbbandgehäuses (10) angeordneten Rollenpaaren, die bei Einsetzen des Farbbandgehäuses in den Drucker automatisch mit einem Antrieb gekuppelt werden.The drive of the respective ribbon consists of pairs of rollers arranged inside the ribbon housing (10), which are automatically coupled to a drive when the ribbon housing is inserted into the printer.
Das Farbbandgehäuse (10) ist für alle Farbbänder einheitlich mit einem ersten Paar Lagerzapfen (11a,11b) versehen und mit einem gewissen Abstand mit einem zweiten Paar Lagerzapfen (12a und 12b). Sodann ist auf den Breitseiten (3 und 4) jeweils ein ebener Auflagervorsprung (13a und 13b) angespritzt.The ribbon housing (10) is uniformly provided for all ribbons with a first pair of bearing pins (11a, 11b) and at a certain distance with a second pair of bearing pins (12a and 12b). A flat support projection (13a and 13b) is then injection molded onto the broad sides (3 and 4).
Das Farbbandgehäuse (10) gemäß den Fig. 1 und 2 wird schon nach seiner Fertigung entweder mit einem Einfarben-Farbband (7) oder mit einem Mehrfarben-Farbband (8) gefüllt und wie üblich mit einem Deckel verschlossen.The ribbon housing (10) according to FIGS. 1 and 2 is already filled either with a single-color ribbon (7) or with a multicolor ribbon (8) and closed as usual with a lid.
An einem Druckerrahmen (14) eines Druckers, der nur für Einfarben-Farbbänder (7) ausgerüstet ist (Fig. 3), befinden sich für die Lagerzapfen (11a und 11b) bzw. für die Lagerzapfen (12a und 12b) je ein oben offenes Lager (15) und ein solches Lager (16) für eine stationäre Farbbandkassette (1).On a printer frame (14) of a printer, which is only equipped for single-color ribbons (7) (Fig. 3), there are one for the bearing journals (11a and 11b) and one for the bearing journals (12a and 12b) Bearing (15) and such a bearing (16) for a stationary ribbon cassette (1).
An einem anderen Druckerrahmen (14) eines Druckers, der nur oder auch für Mehrfarben-Farbbänder (8) ausgelegt ist (Fig. 4), befindet sich zumindest eine Nockenkurve (17) drehfest auf einer drehangetriebenen Nockenwelle (18).On another printer frame (14) of a printer, which is designed only or also for multicolor ink ribbons (8) (FIG. 4), there is at least one cam curve (17) in a rotationally fixed manner on a rotationally driven camshaft (18).
Das Farbbandgehäuse (10) stützt sich mit dem ebenen Auflagervorsprung (13b bzw. 13a) auf diese Nockenkurve (17), so daß bei deren Drehung das Farbbandgehäuse (10) jeweils in den Pfeilrichtungen (19) auf eine der Farbbandspuren unterschiedlicher Farbe entsprechend der beschriebenen Nickbewegungen eingestellt wird.The ribbon housing (10) is supported with the flat support projection (13b or 13a) on this cam curve (17), so that when the ribbon housing (10) rotates in the direction of the arrow (19) one of the ribbon tracks of different colors corresponding to that described Pitch movements is set.
