Description

Die Erfindung bezieht sich auf eine ansteuerbare, mit­ tels Umschlingungsantrieb bewirkte Bahnbewegung und Positionierung des Schlittens bei Lineareinheiten. Dabei hat sich gezeigt, daß die geforderte Bahn- bzw. Positioniergenauigkeit oftmals nicht erreicht werden konnte. Dies trifft bei verhältnismäßig großen Längen des Verfahrweges bzw. der Lineareinheit verstärkt zu. Auch die Verfahr- und Haltekraft ist nicht immer ausrei­ chend. Beim Plotten und beim Bearbeiten von Werk­ stücken kann es zu unzulässigen Toleranzabweichungen mit weiteren nachteiligen Folgen kommen. Die ganze Anlage ist einer starken Beanspruchung mit der Folge von Verschleiß und hohen Wartungsaufwand ausge­ setzt.The invention relates to a controllable, with belt motion caused by the belt drive and positioning of the slide on linear units. It has been shown that the required rail or Positioning accuracy can often not be achieved could. This applies to relatively long lengths of the travel path or the linear unit. The traversing and holding force is not always sufficient accordingly. When plotting and editing work there may be inadmissible tolerance deviations come with further adverse consequences. The whole The system is subject to heavy use from wear and high maintenance puts.

Aufgabe der Erfindung ist es daher mit geringem Auf­ wand und einfachen baulichen Mitteln eine betriebssi­ chere, verschleißarme Vorschubeinrichtung für Linea­ reinheiten der vorgenannten Gattung zu schaffen und bei der die bekannten Nachteile vermieden werden. Da­ bei soll auch bei gesteigerter Verfahrgeschwindigkeit, hoher Beschleunigungs- bzw. Verzögerung und großer Schlittenmasse sowie bei starken Bearbeitungskräften die Bahn- und Positioniergenauigkeit erhöht werden. Auch soll die Haltbarkeit und die Wirtschaftlichkeit ge­ steigert und die Belastung, Verschleiß und der War­ tungsaufwand gesenkt werden.The object of the invention is therefore with little on wall and simple structural means an operational safety Chere, low-wear feed device for Linea to create purities of the aforementioned type and in which the known disadvantages are avoided. because at should also with increased travel speed, high acceleration or deceleration and large Slide mass as well as with strong machining forces the path and positioning accuracy can be increased. The durability and economy should also ge increases and the load, wear and the war effort can be reduced.

Erfindungsgemäß wird dies dadurch erreicht, indem eine Lineareinheit mindestens zwei motorisch angetrie­ bene Antriebsscheiben aufweist und jeder Antriebs­ scheibe ein Antriebsmotor zugeordnet ist, wobei die Antriebsmotoren vorzugsweise in Bezug zueinander ei­ nen synchronen Bewegungsablauf aufweisen und mit­ tels elektrischer Verknüpfung synchron miteinander ge­ koppelt sind. Dabei kann die elektrische Verknüpfung durch Übertragung einer übereinstimmenden Anzahl elektrischer Impulse auf die regelbaren Motoren erfol­ gen.According to the invention this is achieved in that a linear unit is driven by at least two motors bene drive pulleys and each drive disk is assigned a drive motor, the Drive motors preferably in relation to each other have a synchronous movement and with electrical connection synchronously with each other are coupled. The electrical connection can by transferring a matching number electrical impulses on the controllable motors gene.

Die Ausgestaltung der Erfindung sowie vorteilhafte Weiterbildungen sind den Patentansprüchen zu entneh­ men. Weitere Vorteile, Einzelheiten und Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung und Zeichnung.The design of the invention and advantageous Further developments can be found in the patent claims men. Other advantages, details and characteristics of the Invention emerge from the following description and drawing.

In der Zeichnung sind einige Ausführungsbeispiele der Erfindung schematisch dargestellt. Es zeigt:Some exemplary embodiments are shown in the drawing the invention is shown schematically. It shows:

Fig. 1 eine Lineareinheit von der Seite, Fig. 1 is a linear unit from the side,

Fig. 2 eine x-y Bewegungseinheit, Fig. 2 is an xy displacement unit,

Fig. 3 eine Lineareinheit, Fig. 3 is a linear unit,

Fig. 4 die beidseitige Lagerung einer Antriebs- bzw. Spannscheibe und Fig. 4 shows the double-sided mounting of a drive or tensioning disc and

Fig. 5 eine Lineareinheit aus zwei Linearachsen zu­ sammengesetzt. Fig. 5 is a linear unit composed of two linear axes.

Bei der Lineareinheit gemäß Fig. 1 werden die beiden Antriebsscheiben 1 von einem Synchronriemen 7 oder einer Kette umschlungen. Dadurch ist eine formschlüs­ sige Antriebsverbindung gegeben. Der Schlitten 6 wird durch die Führungsschiene 8 geführt und ist an der Rie­ meneinspannstelle 9 mit dem Synchronriemen 7 verbun­ den. Zum Einstellen der vorgesehenen Riemenvor­ spannkraft soll mindestens eine Antriebsscheibe 1 in Bezug zur gegenüberliegenden Antriebsscheibe 1 und zur Führungsschiene 8 verstellbar gehalten sein. Jeder Antriebsscheibe 1 ist ein Antriebsmotor 2 zugeordnet. Dabei kann es zweckmäßig sein ein Getriebe zwischen­ zuschalten oder eine Motor-Getriebeeinheit 2 mit ange­ flanschter Antriebsscheibe 1 auszuführen. Die Motoren 2 können regelbar als Norm-, Stell-, Schritt-, Servo-, Brems- oder Spezialmotoren ausgebildet sein. Durch elektrische Verknüpfung 3 haben beide Motoren 2 ei­ nen synchronen Lauf.In the linear unit according to FIG. 1, the two drive pulleys 1 are wrapped in a synchronous belt 7 or a chain. This gives a positive drive connection. The carriage 6 is guided by the guide rail 8 and is at the Rie meneinspannstelle 9 with the timing belt 7 verbun the. To adjust the tension provided Riemenvor to be adjustably held in relation to the opposite drive pulley 1 and the guide rail 8 at least one drive pulley. 1 A drive motor 2 is assigned to each drive pulley 1 . It may be useful to connect a gear between or to execute a motor-gear unit 2 with a flanged drive disk 1 . The motors 2 can be designed to be adjustable as standard, servo, step, servo, brake or special motors. Through electrical connection 3 , both motors 2 have a synchronous run.

Dabei soll zwischen den Motoren 2 eine Null-Justie­ rung einstellbar sein. Dadurch kann der vorgesehene Bahnverlauf und die Positionierung des Schlittens 6 ex­ akt eingehalten werden. Dabei ergibt sich eine wechsel­ seitige Drehrichtung 10 der Antriebsscheiben 1 und eine Hin- und Herbewegung 11 des Schlittens 6. Durch die Verwendung zweier synchron angetriebener Antriebs­ scheiben 1 wird die Länge des Last- und Leertrums des Synchronriemens 7 verkürzt und dessen Belastung so­ wie der ganzen Lineareinheit herabgesetzt und vielfälti­ ge Störbeeinflussung vermieden und die Verfahrge­ schwindigkeit des Schlittens 6 gesteigert. Gegebenen­ falls kann auch die Vorspannkraft des Synchronriemens 7 reduziert werden.A zero adjustment should be adjustable between the motors 2 . As a result, the intended path and the positioning of the carriage 6 can be adhered to exactly. This results in an alternating direction of rotation 10 of the drive disks 1 and a back and forth movement 11 of the carriage 6 . By using two synchronously driven drive pulleys 1 , the length of the load and empty run of the synchronous belt 7 is shortened and its load as well as the entire linear unit is reduced and diverse interference is avoided and the speed of the carriage 6 is increased. If necessary, the pretensioning force of the synchronous belt 7 can also be reduced.

Die Fig. 2 zeigt eine x-y Bewegungseinheit die aus zwei Lineareinheiten gebildet ist. Dabei stellt die Brüc­ ke 12 die Verbindung zwischen der Führungsschiene 8 und dem Schlitten 6a her. Dadurch ergibt sich eine Be­ weglichkeit des Schlittens 6 auf der x und y Achse. Zwi­ schen beiden Lineareinheiten ist eine elektrische Ver­ knüpfung 13 vorgesehen. FIG. 2 shows an xy displacement unit which is formed of two linear units. The bridge 12 creates the connection between the guide rail 8 and the slide 6 a. This results in a mobility of the carriage 6 on the x and y axis. Between the two linear units, an electrical linkage 13 is provided.

Die in Fig. 3 dargestellte Lineareinheit wird durch parallele Linearachsen 4 gebildet indem die Schlitten 6 mittels einer Traverse 5 verbunden sind. Jeder Linear­ achse 4 ist eine Antriebsscheibe 1 mit einem Antriebs­ motor 2 zugeordnet. Diese sind mittels elektrischer Ver­ knüpfung 3 synchron regelbar. Dabei werden die Schlit­ ten 6 und die Traverse 5 in Richtung R bewegt.The linear unit shown in FIG. 3 is formed by parallel linear axes 4 by the carriages 6 being connected by means of a cross member 5 . Each linear axis 4 is assigned a drive pulley 1 with a drive motor 2 . These can be controlled synchronously by means of electrical connection 3 . The Schlit ten 6 and the cross member 5 are moved in the R direction.

Gemäß Fig. 4 ist die Antriebsscheibe 1 zur Erzielung eines gleichmäßigen, lastunabhängigen Rundlaufs beid­ seitig an der Führungsschiene 8 bzw. einer Haltevor­ richtung in Lagern 14 gelagert.According to FIG. 4, the disk drive 1 is to obtain a uniform load-independent concentricity beid each other on the guide rail 8 and a Haltevor direction in bearings 14 mounted.

Zwei zusammengesetzte Linearachsen 16 wie in Fig. 5 dargestellt bilden eine Lineareinheit mit großen Verfahrweg des Schlittens 6. Dabei sind die Motoren 2 jeder Linearachse 16 durch elektrische Verknüpfung verbunden. Zwischen den Linearachsen 16 ist eine elek­ trische Verknüpfung 13 vorgesehen.Two composite linear axes 16 as shown in FIG. 5 form a linear unit with a large travel of the carriage 6 . The motors 2 of each linear axis 16 are connected by electrical connection. An electrical link 13 is provided between the linear axes 16 .
