Abstract

A device for printing on slide frames (2) or the like, having at least one printing apparatus (3) arranged above a transport apparatus for successive advancement and preferably having a needle printer, is constructed in such a way that the printing apparatus is arranged so as to be slightly movable counter to an action of force - preferably by gravity - transversely relative to the plane of the direction of transport of the slide frames or the like. Automatic height-adjustment of the printing apparatus or individual adaptation to the respective thickness of the slide frame or the like to be printed is thus achieved. A further advantage consists in the fact that the printing apparatus can be removed for the purpose of cleaning or servicing without using tools.

Description

Die Erfindung betrifft eine Vorrichtung zum Bedrucken von Diarahmen od. dgl., mit wenigstens einer über einer Transporteinrichtung zum nacheinanderfolgenden Heranführen angeordneten, vorzugsweise einen Nadeldrucker aufweisenden Druckeinrichtung.The invention relates to a device for printing slide frames or the like, with at least one printing device arranged above a transport device for successive feeding, preferably having a dot matrix printer.

Es ist bekannt, zur Beschriftung von Diarahmen od. dgl. Nadeldrucker einzusetzen, deren Druckköpfe ortsfest ober­halb einer Transportbahn für liegend herangeführte Diarah­men angeordnet sind. Der Transport der Diarahmen erfolgt in der Transporteinrichtung beispielsweise mittels einer Kette mit Mitnehmern oder mittels eines Mitnehmer aufweisen­den Zahnriemens. Der Durchlauf der Diarahmen unterhalb der Druckeinrichtung erfolgt kontinuierlich, und der Druckvorgang erfolgt, während der Diarahmen unter dem Druckkopf der Druckeinrichtung her bewegt wird. Derartige Vorrichtungen werden beispielsweise in gesonderten Beschrif­tungsanlagen eingesetzt oder auch beispielsweise an Dia-Rah­mungsmaschinen als Zusatzgeräte angebaut. Die Druckeinrich­tung kann einen Druckkopf oder auch mehrere Druckköpfe aufweisen.It is known to use dot matrix printers or the like for the labeling of slide frames, the print heads of which are arranged in a stationary manner above a transport path for slide frames which are brought in lying down. The slide frames are transported in the transport device, for example by means of a chain with drivers or by means of a toothed belt having drivers. The passage of the slide frames below the printing device takes place continuously, and the printing process takes place while the slide frame is being moved under the print head of the printing device. Devices of this type are used, for example, in separate labeling systems or are also installed, for example, on slide framing machines as additional devices. The printing device can have one print head or a plurality of print heads.

Für den Druckvorgang ist eine genaue Einstellung der Vorrichtung auf die Dicke des zu bedruckenden Flächenelemen­tes bzw. die Dicke des Diarahmens erforderlich. Insbesonde­re bei Diarahmen variiert die Rahmendicke von Fabrikat zu Fabrikat, und auch innerhalb gleicher Fabrikate sind Dickenunterschiede feststellbar. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genann­ten Art so auszubilden, daß eine automatische Einstellung auf die jeweilige Rahmendicke erfolgt.For the printing process, an exact adjustment of the device to the thickness of the surface element to be printed or the thickness of the slide frame is required. In the case of slide frames in particular, the frame thickness varies from make to make, and differences in thickness can also be determined within the same make. The invention has for its object to design a device of the type mentioned so that an automatic adjustment to the respective frame thickness takes place.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Druckeinrichtung entgegen einer Krafteinwirkung quer zu der Ebene der Transporteinrichtung der Diarahmen od. dgl. leicht bewegbar angeordnet ist. Vorzugsweise ist vorgesehen, daß die Ebene der Transportrichtung der Diarah­men od. dgl. im wesentlichen horizontal verlaufend angeord­net ist und die Krafteinwirkung durch Schwerkrafteinwirkung erfolgt. Die Druckeinrichtung wird somit durch einen auf der Transporteinrichtung herangeführten Diarahmen um ein genau der Dicke des Diarahmens entsprechendes Maß angehoben, und damit stellt sich die Höhe der Druckein­richtung oberhalb der Transporteinrichtung selbsttätig und genau auf die individuelle Rahmendicke des entsprechen­den Diarahmens od. dgl. ein.According to the invention, this object is achieved in that the pressure device is arranged such that it can be moved transversely to the plane of the transport device of the slide frame or the like, counter to the action of force. It is preferably provided that the plane of the transport direction of the slide frames or the like is arranged to run essentially horizontally and the force is exerted by gravity. The printing device is thus raised by a slide frame brought up on the transport device by an amount corresponding exactly to the thickness of the slide frame, and the height of the printing device above the transport device is thus automatically and precisely adjusted to the individual frame thickness of the corresponding slide frame or the like.

In zweckmäßiger Ausgestaltung ist vorgesehen, daß in Transportrichtung gesehen vor und auch hinter dem Druckkopf der Druckeinrichtung an dieser oberhalb der Bewegungsbahn der Diarahmen od. dgl. Gleiteinrichtungen vorgesehen sind. Diese Gleiteinrichtungen sind vorzugsweise als Kugellager ausgebildet.In an expedient embodiment it is provided that, seen in the direction of transport, sliding devices are provided in front of and also behind the print head of the printing device, above the movement path of the slide frames or the like. These sliding devices are preferably designed as ball bearings.

Mit der erfindungsgemäßen Vorrichtung ist ein Bedrucken von Diarahmen od. dgl. ohne Einstellung auf die jeweilige Rahmendicke in gleichbleibender Qualität möglich. Ein weiterer Vorteil der Erfindung besteht darin, daß die Druckeinrichtung aus ihrer Führung leicht herausnehmbar ist. Die Druckeinrichtung kann auf diese Weise nach dem Herausnehmen gesäubert und wieder eingesteckt werden, ohne daß irgendwelche Werkzeuge od. dgl. erforderlich wären.With the device according to the invention, printing of slide frames or the like is possible without adjustment to the respective frame thickness in a constant quality. Another advantage of the invention is that the printing device can be easily removed from its guide. In this way, the printing device can be cleaned after being removed and reinserted without any tools or the like being required.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten schematischen Zeichnung erläutert. Es zeigen:

  • Fig. 1 eine schematische Seitenansicht einer Vorrichtung gemäß der Erfindung;
  • Fig. 2 eine schematische Schnittdarstellung längs der Linie II-II in Fig. 1.
An embodiment of the invention is explained below with reference to the accompanying schematic drawing. Show it:
  • Figure 1 is a schematic side view of a device according to the invention.
  • FIG. 2 shows a schematic sectional illustration along the line II-II in FIG. 1.

Eine Vorrichtung zum Bedrucken von Diarahmen weist eine Transporteinrichtung zum nacheinanderfolgenden Heranfüh­ren von liegenden Diarahmen 2 auf. Es ist lediglich ein Diarahmen 2 dargestellt, der in Pfeilrichtung A (Transport­richtung) kontinuierlich bewegt wird. Die Bewegung erfolgt dabei beispielsweise über eine (nicht dargestellte) Kette mit Mitnehmern (ebenfalls nicht dargestellt).A device for printing slide frames has a transport device for the successive feeding of lying slide frames 2. Only one slide frame 2 is shown, which is moved continuously in the direction of arrow A (transport direction). The movement takes place, for example, via a chain (not shown) with drivers (also not shown).

Eine insgesamt mit 3 bezeichnete Druckeinrichtung weist an einem Rahmen 4 einen Nadeldrucker 5 mit einem Druckkopf 6 auf. An dem Rahmen 4 sind weiterhin Farbbandrollen 7 und 8 gelagert, deren Farbband 9 über Umlenkrollen 10, 11, 12 und 13 unterhalb des Druckkopfes 6 geführt ist. In Transportrichtung A gesehen vor dem Druckkopf 6 der Druckeinrichtung sind Kugellager l3α, 14, 15 und 16 angeordnet. Hinter dem Druckkopf 6 sind Kugellager 17 und 18 vorgesehen. Der Rahmen 4 und damit die gesamte Druckeinrichtung 3 einschließlich der Farbbänder, der Farbbandführungen und der Kugellager sind vertikal bewegbar angeordnet. Hierzu ist eine (nicht dargestellte) Führung vorgesehen, in der die gesamte Druckeinrichtung in vertika­ler Richtung spielfrei aber leicht beweglich führbar ist.A printing device, generally designated 3, has a dot matrix printer 5 with a print head 6 on a frame 4. Ribbon rolls 7 and 8 are also mounted on the frame 4, the ribbon 9 of which is guided below the print head 6 via deflection rolls 10, 11, 12 and 13. Seen in the direction of transport A in front of the print head 6 of the printing device, ball bearings 13a, 14, 15 and 16 are arranged. Ball bearings 17 and 18 are provided behind the print head 6. The frame 4 and thus the entire printing device 3 including the ink ribbons, the ink ribbon guides and the ball bearings are arranged to be vertically movable. For this purpose, a guide (not shown) is provided, in which the entire printing device can be guided in the vertical direction without play but easily movable.

Wenn sich kein Diarahmen 2 unterhalb der Druckeinrichtung 3 befindet, liegt die Druckeinrichtung mit den Kugellagern 13 bis 18 auf der Gleitbahn 19 der Transporteinrichtung 1 auf. Dabei wird die Anordnung so gestaltet, daß bei auf der Gleitbahn 19 aufliegenden Kugellagern l3α bis 18 zwi­schen der Gleitbahn und der Unterseite des Farbbandes 9 noch ein geringfügiger Abstand vorhanden ist.If there is no slide frame 2 below the printing device 3, the printing device with the ball bearings 13 to 18 rests on the slideway 19 of the transport device 1. The arrangement is designed in such a way that when ball bearings l3α to 18 rest on the slideway 19 between the slideway and the underside of the ink ribbon 9 there is still a small gap.

Wenn ein Diarahmen 2 aus Richtung A herangeführt wird, wird die gesamte Druckeinrichtung 3 um das Maß der Dicke dieses Diarahmens angehoben, da der Diarahmen 2 zunächst in den Bereich des Kugellagers l3α und dann anschließend in den Bereich der nachfolgenden Kugellager gerät und somit zwangsläufig die Druckeinrichtung 3 angehoben wird. Dadurch erfolgt eine automatische Höhenjustage der Druckein­richtung und letztlich des Druckkopfes 6 relativ zu dem zu bedruckenden Diarahmen 2.If a slide frame 2 is brought in from direction A, the entire printing device 3 is raised by the measure of the thickness of this slide frame, since the slide frame 2 first gets into the area of the ball bearing l3α and then subsequently into the area of the subsequent ball bearings and thus inevitably the printing device 3 is raised. This results in an automatic height adjustment of the printing device and ultimately of the print head 6 relative to the slide frame 2 to be printed.

Zum Reinigen bzw. zum Warten der Druckeinrichtung 3 kann diese mit dem Rahmen 4 ohne weiteres nach oben aus ihrer Führung herausgenommen werden, ohne daß Werkzeuge od. dgl. erforderlich wären.For cleaning or maintenance of the printing device 3, the latter can be removed with the frame 4 from its guide upwards without any tools or the like being required.
