Abstract

Two cylindrical guide rails (6, 6'), arranged parallel to each other, are mounted in the recording apparatus for straight guiding. Provided in the top part of the carriage (1) are at least two running rollers (5) made of plastic, mounted in mirror image to a vertical plane (a-a') containing the mid-axis of the top guide rail (6), the axes of which running rollers enclose an angle of approximately 90 DEG . Provided as a support roller in the bottom part (4) of the carriage (1) is a further running roller (5') arranged at an angle to the vertical plane (b-b') containing the mid-axis of the bottom guide rail (6'). In order to achieve a mounting without play, permanent magnets (7) are arranged on or in the carriage (1), which permanent magnets interact with the guide rails (6, 6') made of ferromagnetic material and form a magnetic spring mounting. The invention is used in compensographs. <IMAGE>

Description

Die Erfindung betrifft ein Registriergerät mit einem quer zur Bewegungsrichtung eines Aufzeichnungsträgers in definierte Stellungen bewegbaren, Schreib- oder Druckeinrichtungen tragen­den Schreibwagen, der auf zwei Führungsschienen gelagert ist.The invention relates to a recording device with a writing carriage which can be moved transversely to the direction of movement of a recording medium into defined positions and which carries writing or printing devices and is mounted on two guide rails.

Bei bekannten elektrischen Registriergeräten dieser Bauart wird der mit Gleitlagern versehene Schreibwagen mit Hilfe eines meßsignalgesteuerten Stellmotors auf den Führungsschienen be­wegt.
Aus Toleranzgründen kann die Führung nicht spielfrei erfolgen, das Lagerspiel vergrößert sich überdies mit der Zeit aufgrund von Abnutzungserscheinungen und führt zu Fehlern bei der Auf­zeichnung.
Es sind auch Schreibwagenführungen mit Kugellagern bekannt, bei denen durch aufwendige Justierung oder durch Federung eines Kugellagers das Lagerspiel auf ein Minimum gebracht wird. Nach­teilig ist der mit der Zeit auftretende Verschleiß der Füh­rungsschienen, der Kugellageraußenringe und das störende Lauf­geräusch.In known electrical recording devices of this type, the writing carriage provided with sliding bearings is moved on the guide rails with the aid of a measuring signal-controlled servomotor.
Due to tolerance reasons, the guidance cannot take place without play, the bearing play also increases over time due to wear and tear and leads to errors in the recording.
There are also known typewriter guides with ball bearings in which the bearing play is brought to a minimum by complex adjustment or by springing a ball bearing. Disadvantages are the wear of the guide rails, the ball bearing outer rings, which occurs over time, and the annoying running noise.

Es besteht somit die Aufgabe, den Schreibwagen eines Registrier­geräts so auf seinen Führungsschienen zu lagern, daß bei ge­ringstmöglichem Spiel ein wartungsfreier Betrieb über längere Zeiträume möglich ist, daß er möglichst geräuschlos arbeitet und daß er zum Austausch der Schreibeinrichtung um eine Füh­rungsschiene schwenkbar ausgeführt ist.It is therefore the task of storing the writing carriage of a recording device on its guide rails in such a way that maintenance-free operation over longer periods of time is possible with the least possible play, that it works as quietly as possible and that it is designed to be pivotable about a guide rail for replacing the writing device.

Eine Lösung der Aufgabe läßt sich mit einem Registriergerät mit den Merkmalen des Anspruchs 1 erreichen.A solution to the problem can be achieved with a recording device with the features of claim 1.

In einer bevorzugten Ausführungsform sind die Mittel zur kraft­schlüssigen Verbindung der Laufflächen der Laufrollen mit den Mantelflächen der Führungsschienen Permanentmagnete, die in dem Schreibwagen angeordnet sind und mit den aus ferromagnetischem Material hergestellten Führungsschienen zusammenwirken und so eine magnetische Federung bilden.
Mit Laufrollen aus Kunststoff läßt sich das Registriergerät geräuscharm betreiben.In a preferred embodiment, the means for non-positively connecting the running surfaces of the rollers to the Sheath surfaces of the guide rails permanent magnets, which are arranged in the writing carriage and interact with the guide rails made of ferromagnetic material and thus form a magnetic suspension.
The recording device can be operated quietly with plastic rollers.

Zur Erläuterung der Erfindung ist in den Figuren 1 und 2 ein Ausführungsbeispiel in zwei Ansichten dargestellt und im fol­genden beschrieben.To explain the invention, an embodiment is shown in two views in Figures 1 and 2 and described below.

Der Schreibwagen 1 besteht aus einem Oberteil 2, einem Mittel­teil 3 und einem Unterteil 4. An dem plattenartig ausgeführten Mittelteil 3 ist die hier der Übersichtlichkeit halber nicht eingezeichnete Schreibeinrichtung, z. B. ein Tintenstrahl-Druck­kopf, auswechselbar gelagert.
Der obere Teil 2 des Schreibwagens 1 ist so ausgebildet, daß in ihm vier Laufrollen 5 eingesetzt werden können, die spiegel­bildlich zu einer die Mittelachse einer zylindrischen Führungs­schiene 6 aus ferromagnetischem Material enthaltenden senkrech­ten Ebene a - a′ gelagert sind, wobei ihre Achsen einen Winkel von etwa 90° einschließen.
Zur kraftschlüssigen Verbindung der Laufflächen der Laufrollen 5 mit der Mantelfläche der Führungsschiene 6 ist in oder an dem Oberteil 2 des Schreibwagens 1 ein Permanentmagnet 7 angebracht, der mit der Führungsschiene als magnetischen Rückschluß zusam­menwirkt und eine magnetische Federung bildet.The writing carriage 1 consists of an upper part 2, a middle part 3 and a lower part 4. On the plate-like middle part 3, the writing device not shown here for the sake of clarity, e.g. B. an inkjet printhead, replaceable.
The upper part 2 of the carriage 1 is designed so that four rollers 5 can be used in it, which are mirror images of a vertical plane containing the central axis of a cylindrical guide rail 6 made of ferromagnetic material a - a ', their axes an angle of enclose about 90 °.
For the positive connection of the running surfaces of the rollers 5 with the outer surface of the guide rail 6, a permanent magnet 7 is attached in or on the upper part 2 of the writing carriage 1, which cooperates with the guide rail as a magnetic yoke and forms a magnetic suspension.

Parallel zu der oberen Führungsschiene 6 ist eine untere Füh­rungsschiene 6′ vorgesehen, auf der eine im Unterteil 4 des Schreibwagens 1 angebrachte Laufrolle 5′ abrollt. Die Laufrolle 5′ ist in einem Winkel zu der senkrechten, die Mittelachse der unteren Führungsschiene 6′ enthaltenden Ebene b - b′ angeordnet, wobei der untere Teil 4 so weit abgeknickt ist, daß eine seitliche und einseitige Abstützung erfolgt, die es erlaubt, den Schreibwagen 1 zum Auswechseln seines Schreib­elements oder der Schreibeinrichtung um die Achse der oberen Führungsschiene 6 in Pfeilrichtung zu verschwenken. Zur kraftschlüssigen Verbindung ist in dem Unterteil 4 eben­falls ein Permanentmagnet 7 vorgesehen, der mit der unteren Führungsschiene 6′ zusammenwirkt.
Durch die einseitige Abstützung der Laufrolle 5′ gegen die untere Führungsschiene 6′ wird eine spielfreie Lagerung quer zur Bewegungsrichtung des Schreibwagens 1 erzielt. Die Lauf­rollen 5, 5′ aus Kunststoff vermindern den Verschleiß an den Führungsschienen 6, 6′, wie auch das Laufgeräusch des Schreib­wagens.Parallel to the upper guide rail 6, a lower guide rail 6 'is provided, on which an attached in the lower part 4 of the writing carriage 1 rolls 5'. The roller 5 'is arranged at an angle to the vertical, the central axis of the lower guide rail 6' containing plane b - b ', the lower part 4 is bent so far that there is lateral and one-sided support, which allows the Writing carriage 1 for changing its writing element or the writing device to pivot about the axis of the upper guide rail 6 in the direction of the arrow. For the positive connection, a permanent magnet 7 is also provided in the lower part 4, which cooperates with the lower guide rail 6 '.
Due to the one-sided support of the roller 5 'against the lower guide rail 6' a play-free storage transverse to the direction of movement of the carriage 1 is achieved. The rollers 5, 5 'made of plastic reduce the wear on the guide rails 6, 6', as well as the running noise of the writing carriage.
