The tractors (1a and 1b) have hinged parts which can be adjusted in different hinged positions by pivoting bearings (11). To provide hinged part on printers, particularly dot matrix printers, with simple pivoting bearings that can be produced economically and to eliminate a special fastener for the pivoted positions, a spring steel wire piece (18) cut to length serves as a pivot pin (17) and for fixing of the closed and open end positions of the hinged part (10). The spring steel wire piece (18) is put under tension by bending.

Description

Die Erfindung betrifft eine Transportvorrichtung für Drucker, insbesondere für Matrixdrucker, die für die Führung und/oder den vorschub des Aufzeichnungstrkgers mit paarweise angeordneten Traktorvorrichtungen versehen sind, wobei klappbare Bauteile mittels Gelenklagern befestigt sind.The invention relates to a transport device for printers, in particular for matrix printers, which are provided with paired tractor devices for guiding and / or advancing the record carrier, with foldable components being fastened by means of spherical bearings.

Derartige Transportvorrichtungen dienen dem zeilenweisen, schrittweisen oder kontinuierlichen Vorschub von Aufzeichnungsträgern, die z.B. aus Papierbahnen bestehen. Für einen störungsfreien Betrieb eines Druckers ist es von Bedeutung, die Papierbahn mit ihrem Anfang fachgerecht in die Vorschub- bzw. Führungsorgane der Transportvorrichtung einzulegen.Such transport devices are used for line-by-line, step-by-step or continuous feed of record carriers, which e.g. consist of paper webs. For trouble-free operation of a printer, it is important to properly insert the beginning of the paper web into the feed or guide elements of the transport device.

Beim Einlegen der Papierbahn in die Stifte des Riemenbandes eines Traktors ist es z.B. erforderlich, die Traktorklappen, d.h. Abdeckungen, die die Papierbahn auf den Stiften halten, wegzuschwenken. Trktorklappen sind daher abschwenkbar in Gelenklagern gehalten.When inserting the paper web into the pins of the belt strap of a tractor it is e.g. required, the tractor hatches, i.e. Swing covers that hold the paper web on the pins away. The tractor flaps are therefore held in swivel bearings so that they can be swung out.

Das Einführen der Papierbahn von der Unterseite oder von der Rückseite des Druckers macht bei einigen Druchkerbauformen ebenfalls das Abschwenken von klappbaren Bauteilen mittels Gelenklagern erforderlich.The introduction of the paper web from the underside or from the back of the printer also makes it necessary to swivel foldable components by means of spherical bearings in some types of printer.

Für den Transport ist das Einschwenken von während des Betriebes ausgeschwenkten klappbaren Bauteilen von Vorteil, um Transport- bzw. Verpackungsraum zu sparen.For transport, the swiveling-in of foldable components that are pivoted out during operation is advantageous in order to save transport and packaging space.

Allen erwähnten Beispielen haftet der Nachteil an, daß klappbare Bauteile an Druckern fUr die Gelenklager einen erheblichen Aufwand benötigen. Ein zusätzlicher Aufwand entsteht, wenn der klappbare Bauteil in seinen Klapp-Positionen zusätzlich noch fixiert werden soll. Ein diesbezüglicher Aufwand Ist wirtschaftlich kaum noch zu vertreten.All the examples mentioned have the disadvantage that foldable components on printers require considerable effort for the spherical plain bearings. Additional effort arises if the foldable component is to be additionally fixed in its foldable positions. An effort in this regard is hardly economically viable.

Der Erfindung llegt daher die Aufgabe zugrunde, für klappbare Bauteile an Druckern ein einfaches Gelenklager zu schaffen und ebenso eine einfache Feststellvorrichtung für die Klapp-Positionen.The invention is therefore based on the object of creating a simple articulated bearing for foldable components on printers and also a simple locking device for the foldable positions.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Gelenkzapfen und zur Fixierung einer Schließ- oder Offenstellung des Klappenbauteils ein abgelängtes Federstahldrahtstck dient, das durch Krümmung unter Vorspannung gesetzt ist. Diese Erfindung verwirklicht auf wirtschaftliche und einfache Weise ein Gelenk und erlaubt gleichzeitig die Feststellung des Klappendauteils in gewünschten Endpositionen,The object is achieved in that a cut spring steel wire piece is used as a hinge pin and for fixing a closed or open position of the flap component, which is put under tension by curvature. This invention realizes an articulation in an economical and simple manner and at the same time allows the valve end part to be fixed in the desired end positions,

Eine bevorzugte Ausführungsform der Erfindung ist dahingehend gestaltet, daß am Traktorkörper in Vorschbrichtung beabstandete Traktorlager vorgesehen sind, in denen die Enden des Federstahldrahtstucks gelagert sind, daß ferner an dem Klappenbauteil zwischen den Traktorlagern des Traktorkörpers zumindest ein Klappenbauteil-Lager mit einer Durchgangsbohrung für das Federstanldrahtstück vorgesehen ist, daß außerdem in Schließ- und Offenstellung das bzw. die Klappenbauteil-Lager mit äußeren, ebenen Flächen auf einer ebenen Gegenflache des Traktorkorpers anliegen und daß die Bohrungen in den Traktorlagern und in dem Klappenbauteli-Lager in ihrer Achse voneinander abweichen.A preferred embodiment of the invention is designed in such a way that on the tractor body spaced-apart tractor bearings are provided, in which the ends of the spring steel wire stucco are mounted, and that at least one valve component bearing with a through hole for the spring-standing wire piece is provided on the valve component between the tractor bearings of the tractor body is that, in addition, in the closed and open position, the flap component bearing (s) bear with outer, flat surfaces on a flat counter surface of the tractor body and that the bores in the tractor bearings and in the flap component bearing differ in their axes.

Eine funktionell umgekehrte Gestaltung dieser Lösung besteht darin, daß am Klappenbauteil in Vorschubrichtng beabstandete Klappenbautellenden-Lager vorgesehen sind, in denen die Enden des Federstahldrahtstückes gelagert sind, daß ferner an. dem Traktorkörper zwischen den Klappenbauteilenden-Lagern zumindest ein Traktorlager mit einer Durchgangsbohrung für das Federstahldrahtstück vorgesehen ist, daß außerdem in Schließ- und Offenstellung die Klappenbauteilanden-Lager mit äußeren ebenen Flächen auf einer ebenen Gegenfläche des Traktorkörpers anliegen und daß die Durchgangsbohrungen in den Traktorlagern und in den Klappenbauteilenden-Lagern in inrer Achse voneinander abweichen.A functionally reversed design of this solution consists in that flap component end bearings, in which the ends of the spring steel wire piece are mounted, are provided on the flap component in the feed direction. the tractor body between the flap component end bearings at least one tractor bearing with a through hole for the spring steel wire piece is provided that in addition in the closed and open position, the flap component parts bearings rest with flat outer surfaces on a flat counter surface of the tractor body and that the through holes in the tractor bearings and in the valve component end bearings differ in their internal axis.

Ein herausfallen des Federstahldrahtstückes kann vermieden werden, indem die Enden des Federstahldrahtstückes angequetscht sind.Falling out of the spring steel wire piece can be avoided by crimping the ends of the spring steel wire piece.

Die erfindungsgemäßen Wirkungen treten bei Klappenbautilen für Drueker schon dann ein, wenn die parallelen Achsen der Bohrungen in den Iraktorlagern und in den Klappenbauteil-Lagern einen Abstand von etwa 0,8 mm aufweisen.The effects according to the invention already occur in valve components for Druekers when the parallel axes of the bores in the Iraqi bearings and in the valve component bearings are at a distance of approximately 0.8 mm.

Die praktischen Fixierstellungen werden vorteilhafterweise dadurch erzlelt. daß die äußere ebene Gegenfläche des Traktorkörpers zu der Fläche der Klappenbauteil-Lager für Schließ- bzw. Offenstellung unter einem Winkel von 90° zueinander verlaufen.The practical fixing positions are advantageously achieved. that the outer flat counter surface of the tractor body to the surface of the flap component bearing for the closed or open position at an angle of 90 ° to each other.

Die Anwendung der Erfindung auf einen Matrixdrucker ergibt sich dadurch, daß das Klappenbautil aus einer Abdeckklappe für das Riemenband der Traktorvorrichtung besteht.The application of the invention to a matrix printer results from the fact that the flap component consists of a cover flap for the belt band of the tractor device.

Eine andere Anwendbarkeit wird dadurch erzielt. daß das Klappenbautell aus einer seitlichen Führungsklappe für den Aufzeichnungsträger besteht.Another applicability is thereby achieved. that the flap component consists of a lateral guide flap for the record carrier.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend näher beschrieben.Embodiments of the invention are shown in the drawing and are described in more detail below.

Es zeigen:

  • Fig. 1 den oberen Teil einer Traktorvorrichtung eines Matrixdruckers in perspektivischer Ansicht und
  • Fig. 2 den rechten Teil einer Transportvorrichtung mit Traktorvorrichtung und einer zusätzlichen Führung für den Aufzeichnungsträger etwa in Transportrichtung des Aufzeichnungsträgers gesehen.
Show it:
  • Fig. 1 shows the upper part of a tractor device of a matrix printer in a perspective view
  • Fig. 2 seen the right part of a transport device with a tractor device and an additional guide for the record carrier approximately in the transport direction of the record carrier.

Die Transportvorrichtung gemäß Fig. list ohne den Aufzelchnungsträger gezeichnet. Die dargestellte Transportvorrichtung ist jedoch paarweise links und rechts vom Aufzeichnungsträger angeordnet. In Fig. list die llnke Traktorvorrichtung la und in Fig. 2 die rechte Traktorvorrichtung 1b sichtbar, wobei beide Traktorvorrichtungen 1a, 1b auf einer Befestigungsstange 2 und einer Antriebsachse 3 geführt sind, die selbst durch Seitenträger 4 und Einstellschrauben 5 genau parallel eingestellt sind. Die Befestigungsstange 2 verläuft in Fig. 1 durch die Bohrung 2a und die im Querschnitt quadratische Antriebsachse 3 verläuft durch eine Vierkantbuchse, die in der Bohrung 3a eingesetzt ist. Die Antriebsachse 3 ist hierbei in der im Seitentrager 4 befestigten Buchse 6 drehgelagert. Der Aufzelchnugsträger liegt an einer Stelle auf den Flügeln 7 der Leitwandklappe 8 und später an einer anderen Stelle auf der Auflage 9 auf.The transport device according to Fig. List drawn without the Aufzechchnungträger. However, the transport device shown is arranged in pairs to the left and right of the record carrier. In Fig. List the left tractor device la and in Fig. 2, the right tractor device 1b visible, both tractor devices 1a, 1b are guided on a mounting rod 2 and a drive shaft 3, which themselves are set exactly in parallel by side bracket 4 and adjusting screws 5. The fastening rod 2 runs in FIG. 1 through the bore 2a and the drive shaft 3, which is square in cross section, runs through a square bushing which is inserted in the bore 3a. The drive axle 3 is in this case rotatably supported in the bushing 6 fastened in the side carrier 4. The Aufzelchnugträger is at one point on the wings 7 of the baffle flap 8 and later at another location on the support 9.

Die beiden in den Fig. 1 und 2 dargestellten Ausführungsbeispiele besitzen für ihre Klappenbauteile 10 Gelenklager 11. Gemäß Flg. 1 besteht das dortige Klappenbauteil 10 aus einer Abdeckklappe 12 und gemäß Fig. 2 besteht das dortige Klappenbauteil 10 aus der Leitwandklappe 8. Währenddem die Leitwandklappe 8 zu Transport- bzw. Verpackungszwecken in Richtung 13 einschweenkbaer ist, dient das Auf-und Einschwenken der Traktorklappe 12 dem Einlegen des randgelochten Aufzeichnungsträgers, d. h. der randgelochten Papierbahn. Die Papierbahn wird mit ihrer Lochung in die Stifte 14 des Riemenbandes 15 eingelegt, das im Traktorkörper 16 geführt ist. Anschließend wird die Abdeckklappe 12 aus der dargestellten senkrechten Position in die waagerechte Position, in der sie das Riemenband 15 abdeckt, geschwenkt. Die Gelenklager 11 sind nunmehr wie nachfolgend beschrieben ausgebildet:

  • Die Gelenklager 11 weisen Gelenkzapfen 17 in Form von abgelängten Federstahldrahtstücken 18 auf. Am Traktorkörper 16 sind in Vorschubrichtung 19 beabstandet Traktorlager.16a und 16b vorgesehen, in denen die Enden 18a und 18b des Federstahldrahtstückes 18 gelagert sind. Der Klappenbauteil 10 trägt zwei Klappenbauteil-Lager 10a und 100. die Jewells mit einer Durchgangsbohrung 10c versehen sind.
The two exemplary embodiments shown in FIGS. 1 and 2 have 10 spherical bearings 11 for their flap components. 1, the flap component 10 there consists of a cover flap 12 and, according to FIG. 2, the flap component 10 there consists of the guide wall flap 8. While the guide wall flap 8 can be swiveled in the direction 13 for transport or packaging purposes, the tractor flap 12 is swung open and in the insertion of the perforated record carrier, ie the perforated paper web. The paper web is inserted with its perforation into the pins 14 of the belt band 15, which is guided in the tractor body 16. The cover flap 12 is then pivoted from the illustrated vertical position into the horizontal position in which it covers the belt band 15. The spherical bearings 11 are now designed as described below:
  • The spherical bearings 11 have pivot pins 17 in the form of cut spring steel wire pieces 18. Tractor bearings 16a and 16b, in which the ends 18a and 18b of the spring steel wire piece 18 are mounted, are spaced apart on the tractor body 16 in the feed direction 19. The flap component 10 carries two flap component bearings 10a and 100. The jewels are provided with a through hole 10c.

In den Durchgangsbohrungen 10c verläuft das Federstahldrahtstück 18. Die Klappenbauteil-Lager 10a und 10b besitzen äußere, ebene Flächen 10d, die sich auf einer ebenen Gegenfläche 16c des Traktorkörpers 16 aufstützen, wobei das Federstahldrahtstück 18 leicht gekrümmt verlauft, d.h. unter Vorspannung gesetzt ist. Diese Vorspannung wird durch einen Versatz von ca. 0,8 mm zwischen den Achsen der Durchgangsbonrungen 10c und der Bohrungen 16d in den Traktorlagern 16a bzw. 16u erreicht.The spring steel wire piece 18 runs in the through bores 10c. The flap component bearings 10a and 10b have outer, flat surfaces 10d which are supported on a flat counter surface 16c of the tractor body 16, the spring steel wire piece 18 running slightly curved, i.e. is under tension. This preload is achieved by an offset of approximately 0.8 mm between the axes of the through bores 10c and the bores 16d in the tractor bearings 16a and 16u.

Es werden die beschriebenen Wirkungen auch dadurch erzielt, daß zumindest ein am Traktorkörper 16 mittig befestigtes Traktorlager (16a oder 16b) vorgesehen ist und das betreffende Klappenbauteil 10 an seinen Klappenbauteilenden Lager (10a;10b) aufweist.The effects described are also achieved in that at least one tractor bearing (16a or 16b) centrally attached to the tractor body 16 is provided and the flap component 10 in question has bearings (10a; 10b) on its flap component parts.

Das Federstahldrahtstück 18 ist an seinen Enden 18a, 18b gequetscht, um ein Herausfallen zu vertneiden.The spring steel wire piece 18 is crimped at its ends 18a, 18b to prevent it from falling out.

Für das Einlegen der Papierbahn bzw. das Verpacken ist es vorteilhaft, wenn das Klappenbauteil 10 jeweils aufrecht, d.h. senkrecht gestellt und fixiert werden kann. Hierzu verläuft die äußere, ebene Gegenfläche 16c des Traktorkörpers 16 unter 90° zu korrespondierenden Flächen 10d der Klappenbautelllager 10a, 10b. Dieses Prinzip kann sowohl für die Abdeckklappe 12 über dem Hiemenband 15 als auch für die seitliche Leitwandklappe 8 für den Aufzeichnungsträger und beliebig an allen Klappbauteilen eines Druckers, insbesondere eines Mdtrixdruckers, angewendet werden.For the insertion of the paper web or the packaging, it is advantageous if the flap component 10 can in each case be placed upright, ie vertically and fixed. For this purpose, the outer, flat counter surface 16c of the tractor body 16 extends at 90 ° to corresponding surfaces 10d of the flap component bearings 10a, 10b. This principle can be used both for the cover flap 12 over the Hiemenband 15 as well as for the lateral Leitwandklappe 8 for the recording medium and any at all K lappbauteilen a printer, in particular a M d trixdruckers be employed.
