Vorrichtung zur Führung eines mittels einer Spindel angetriebenen SchlittensDevice for guiding a slide driven by a spindle

Die Erfindung betrifft eine Vorrichtung zur Führung eines mittels einer Spindel angetriebenen Schlittens nach den Merkmalen des Oberbegriffs des Anspruchs 1. Derartige Schlitten werden beispielsweise als Träger für Abtastsensoren einer Druckvorlage verwendet, wobei es hier besonders darauf ankommt, daß die optoelektrischen Abtastsensoren mit hoher Genauigkeit entlang der Druckvorlage positioniert werden können. Wegen der hohen Anforderungen an eine exakte spielfreie Führung werden bei bekannten Vorrichtungen voneinander getrennte Mittel für Antrieb und Führung eingesetzt, wobei für den Antrieb Zahnriemen oder Spindeln und zur Führung ein oder mehrere Führungsstangen verwendet werden. Diese Maßnahme wird zwar den gestellten Forderungen gerecht, ist aber sehr aufwendig und für viele Anwendungsfälle zu teuer.The invention relates to a device for guiding a carriage driven by a spindle according to the features of the preamble of claim 1. Such carriages are used, for example, as carriers for scanning sensors of a printing template, whereby it is particularly important here that the opto-electric scanning sensors can be positioned with high accuracy along the printing template. Due to the high requirements for precise, play-free guidance, separate means for drive and guide are used in known devices, with toothed belts or spindles being used for the drive and one or more guide rods for the guide. Although this measure meets the requirements, it is very complex and too expensive for many applications.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, für eine Vorrichtung der im Oberbegriff des Anspruchs 1 genannten Art eine möglichst einfache Lösung anzugeben. 25The present invention is therefore based on the task of providing a solution that is as simple as possible for a device of the type mentioned in the preamble of claim 1. 25

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claim 1. Advantageous further developments of the invention are specified in the subclaims.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Dabei zeigenIn the following, an embodiment of the invention is explained in more detail with reference to the drawing.

Figur 3 ein Detail einer Seitenansicht der Vorrichtung nach Figur 1 in Blickrichtung des Pfeils X2.Figure 3 is a detail of a side view of the device according to Figure 1 in the direction of arrow X2.

Die Figur 1 zeigt den schematischen Aufbau einer optoelektrisehen Abtasteinrichtung, bei der ein eine Lichtabtasteinrichtung 1 tragender Schlitten 2 relativ zu einer Abtastfläche bewegbar gelagert ist. Als Antrieb für den längs einer Kante der im wesentlichen rechteckförmigen Lichtabtasteinrichtung 1 angeordneten Schlitten 2 dient eine durch einen Motor 3 über eine Kupplung 14 angetriebene Spindel 4, die an beiden Enden in Kugellagern 5, 6 geführt ist.Figure 1 shows the schematic structure of an opto-electrical scanning device in which a carriage 2 carrying a light scanning device 1 is mounted so that it can move relative to a scanning surface. The carriage 2 arranged along one edge of the essentially rectangular light scanning device 1 is driven by a spindle 4 driven by a motor 3 via a coupling 14, which is guided at both ends in ball bearings 5, 6.

Wie die Figur 2 zeigt, besteht der Schlitten 2 aus einem U-förmigen Bügel, dessen U-Schenkel als Haltelaschen für die Spindel 4 dienen. Die Befestigung des Schlittens 2 erfolgt mittels zweier Muttern 7, 8 die an den Haltelaschen unter Zwischenlage je einer Feder 9, 10 festgeklemmt werden. Auf diese Weise ist der Schlitten 2 sowohl axial als auch radial spielfrei geführt. Aufgrund dieser exakten Spindelführung bedarf es keiner weiteren Führungselemente, so daß es ausreicht, die Lichtabtasteinrichtung 1 auf der der Spindel gegenüberliegenden Kante lediglich durch ein Stützrad 11 zu führen, das entlang einer Abtastleiste 12 abrollt. Zusätzlich kann, wie die Figur 3 zeigt, an der Unterseite der Auflageleiste 12 eine federnd gelagerte Gegenrolle vorgesehen werden.As shown in Figure 2, the carriage 2 consists of a U-shaped bracket, the U-legs of which serve as retaining lugs for the spindle 4. The carriage 2 is attached using two nuts 7, 8 which are clamped to the retaining lugs with a spring 9, 10 in between. In this way, the carriage 2 is guided axially and radially without play. Due to this precise spindle guide, no further guide elements are required, so that it is sufficient to guide the light scanning device 1 on the edge opposite the spindle using only a support wheel 11 which rolls along a scanning bar 12. In addition, as shown in Figure 3, a spring-mounted counter roller can be provided on the underside of the support bar 12.
