Description

Die Erfindung betrifft eine Schleifmaschine mit einer Schleifeinrichtung zur Bearbeitung einer in einer Förderrichtung relativ zur Schleifeinrichtung verfahrbaren, in einer Bearbeitungsebene angeordneten Werkstückoberfläche, bei der die Schleifeinrichtung eine Vielzahl von Schleifköpfen mit um jeweils eine Achse rotierenden Schleifelementen aufweist und die Schleifköpfe mittels einer endlos umlaufenden Transporteinrichtung in einem Schleifbereich über durch Umlenkung um Umlenkrollen über geradlinige Abschnitte in einem Schleifbereich in einem Winkel zur Förderrichtung verfahrbar sind.The invention relates to a grinding machine with a grinding device for processing a movable in a conveying direction relative to the grinding device, arranged in a working plane workpiece surface, in which the grinding device has a plurality of grinding heads with rotating around one axis grinding elements and the grinding heads by means of an endless circulating transport device in a grinding area over by deflection around pulleys over straight sections in a grinding area at an angle to the conveying direction are movable.

Derartige Schleifmaschinen sind bekannt. EP 1 541 285 A1 offenbart an jeweils einem Schlitten angebrachte Schleifwerkzeuge, die von einer umlaufenden Kette entlang einer Führungsschiene gezogen werden. Die Schleifwerkzeuge bestehen beispielsweise aus Tellerschleifern, deren Rotationsantrieb dadurch erfolgt, dass die Führungsschiene gezahnt ausgebildet ist und ein Zahnrad an einer Hochachse des Tellerschleifers durch die Bewegung des Schleifwerkzeugs im Zusammenwirken mit der Führungsschiene in Rotation versetzt wird. Die Rotationsgeschwindigkeit des Tellerschleifers ist somit abhängig von der Geschwindigkeit, mit der der Tellerschleifer von der Kette gezogen wird. In einer alternativen Ausführungsform weist jeder Tellerschleifer einen eigenen motorischen Antrieb auf. Dabei können die Schleifwerkzeuge auch als Walzenschleifer ausgebildet sein, deren Ausrichtung zur Förderrichtung des Werkstücks unterschiedlich sein kann.Such grinding machines are known. EP 1 541 285 A1 discloses grinding tools mounted on a carriage, respectively, which are drawn by a circulating chain along a guide rail. The grinding tools consist for example of disc grinders whose rotational drive takes place in that the guide rail is formed toothed and a gear on a vertical axis of the disc sander is set by the movement of the grinding tool in cooperation with the guide rail in rotation. The rotational speed of the disc sander is thus dependent on the speed with which the disc sander being pulled by the chain. In an alternative embodiment, each disc sander has its own motor drive. In this case, the grinding tools can also be designed as a roll grinder whose orientation can be different from the conveying direction of the workpiece.

WO 2005/056234 A1 offenbart eine Schleifmaschine mit mehreren Schleifköpfen, die an einer umlaufenden Kette befestigt sind. Die Schleifköpfe sind Tellerschleifer, die mit einer stirnseitigen Fläche die Werkstückoberfläche bearbeiten. Die Schleifmaschine benötigt einen Antriebsmotor für die Transportkette und Antriebsmotoren für jedes Schleifelement. Die Möglichkeit, die Schleifelemente mit einer Rotationsgeschwindigkeit anzutreiben, die von der Transportgeschwindigkeit der Schleifköpfe unabhängig ist, erfordert somit einen hohen Aufwand an Antriebsmotoren. WO 2005/056234 A1 discloses a grinding machine having a plurality of grinding heads attached to a revolving chain. The grinding heads are disc grinders, which process the workpiece surface with an end face. The grinding machine requires a drive motor for the transport chain and drive motors for each grinding element. The ability to drive the grinding elements at a rotational speed that is independent of the transport speed of the grinding heads, thus requiring a lot of effort on drive motors.

Der Erfindung liegt daher die Aufgabe zugrunde, verbesserte Schleifergebnisse durch erhöhte Freiheitsgrade bei der Einstellung der Schleifparameter ohne einen hohen Aufwand für Antriebsmotoren zu ermöglichen.The invention is therefore based on the object to enable improved grinding results by increased degrees of freedom in the adjustment of the grinding parameters without a high cost for drive motors.

Diese Aufgabe wird gemäß Anspruch 1 bei einer Schleifmaschine der eingangs erwähnten Art dadurch gelöst, dass für wenigstens eine Gruppe von mehreren Schleifelementen eine Antriebseinrichtung vorgesehen ist, mit der die Schleifelemente von einem gemeinsamen, für den Drehantrieb dieser Schleifelemente vorgesehenen Motor rotierend angetrieben werden und dass die Antriebseinrichtung aus einer flexiblen Reibschluss- oder Formschlussanordnung besteht, die parallel zu der Transporteinrichtung um Umlenkrollen geführt ist und mit den Achsen der Schleifelemente für einen Rotationsantrieb unabhängig von der Transportgeschwindigkeit der Schleifelemente ausgebildet ist.This object is achieved according to claim 1 in a grinding machine of the type mentioned in that for at least one group of a plurality of grinding elements, a drive device is provided with which the grinding elements of a common, provided for the rotary drive of these grinding elements motor are driven in rotation and that Drive device consists of a flexible Reibschluss- or form-locking arrangement, which is guided parallel to the transport means around pulleys and is formed with the axes of the grinding elements for a rotary drive regardless of the transport speed of the grinding elements.

Bei der erfindungsgemäßen Schleifmaschine ist somit neben der endlos umlaufenden Transporteinrichtung für den umlaufenden Transport der Schleifköpfe wenigstens eine Antriebseinrichtung vorgesehen, die mehrere Schleifelemente, vorzugsweise in gleicher Drehrichtung in Rotation versetzt, sodass für den Drehantrieb dieser mehreren Schleifelemente nur ein Motor benötigt wird. Die Schleifelemente der Gruppe werden durch denselben Motor angetrieben, sodass sich ihre Drehgeschwindigkeit aus der Drehgeschwindigkeit des einen Motors bestimmt. Zweckmäßigerweise sind die Drehgeschwindigkeiten aller Schleifelemente der Gruppe gleich.In the grinding machine according to the invention thus at least one drive means is provided in addition to the endless circulating transport means for the circulating transport of the grinding heads, the plurality of grinding elements, preferably in the same direction of rotation, so that only one motor is required for the rotary drive of these multiple grinding elements. The grinding elements of the group are driven by the same motor, so that their rotational speed determined from the rotational speed of one motor. Conveniently, the rotational speeds of all grinding elements of the group are the same.

Die Antriebseinrichtung besteht vorzugsweise aus einer umlaufenden flexiblen Reibschluss- oder Formschlussanordnung, also vorzugsweise aus einer Antriebskette, einem Antriebszahnriemen oder einem Keilriemen, der mit entsprechenden Gegeneinrichtungen an der Achse des Schleifelements zusammenwirkt. Bevorzugt ist die Ausbildung mit einem umlaufenden Zahnriemen, der gegen Schlupf unanfällig ist.The drive device preferably consists of a circumferential flexible Reibschluss- or form-fitting arrangement, that is preferably of a drive chain, a drive toothed belt or a V-belt, which cooperates with corresponding counter-devices on the axis of the grinding element. Preferred is the design with a circulating toothed belt, which is not susceptible to slippage.

Die erfindungsgemäße Schleifmaschine kann mit einer einzigen Gruppe von Schleifelementen versehen sein. In diesem Fall ist nur eine einzige Antriebseinrichtung mit einem einzigen Motor vorgesehen, der alle Schleifelemente während des Transports mit der endlos umlaufenden Transporteinrichtung antreibt.The grinding machine according to the invention may be provided with a single group of grinding elements. In this case, only a single drive means with a single motor is provided, which drives all the grinding elements during transport with the endless circulating transport device.

In einer bevorzugten Ausführungsform sind zwei Antriebseinrichtungen vorgesehen, die zwei Gruppen von Schleifelementen antreiben. Die Gruppen sind dabei so ausgebildet, dass einander benachbarte Schleifelemente jeweils zu einer anderen Gruppe gehören. Zweckmäßigerweise werden die Schleifelemente der beiden Gruppen in entgegen gesetzten Richtungen angetrieben, wodurch ein gleichmäßigeres Schleifergebnis erzielt wird. Für jede der beiden Gruppen ist dennoch nur ein einziger Antriebsmotor erforderlich.In a preferred embodiment, two drive means are provided which drive two groups of grinding elements. The groups are designed so that adjacent grinding elements each belong to a different group. Advantageously, the grinding elements of the two groups are driven in opposite directions, whereby a more uniform grinding result is achieved. For each of the two groups, however, only a single drive motor is required.

Die Schleifelemente können bevorzugt durch Bürsten gebildet sein, wobei die Achsen, um die die Schleifelemente rotieren, vorzugsweise senkrecht zur Bearbeitungsebene stehen.The grinding elements may preferably be formed by brushes, wherein the axes about which the grinding elements rotate, preferably perpendicular to the working plane.

Die Schleifeinrichtung ist vorzugsweise breiter als die maximale Werkstückbreite, bezogen auf die Förderrichtung, ausgebildet. Der Schleifbereich, in dem die Schleifelemente auf der Werkstückoberfläche wirksam werden, kann insbesondere durch eine geradlinige Strecke gebildet sein, auf der die Schleifköpfe senkrecht zur Förderrichtung über die Oberfläche des Werkstücks transportiert werden und dabei durch die Rotationsbewegung die Werkstückoberfläche bearbeiten. Da die Schleifköpfe umlaufend angetrieben werden, entsteht in Förderrichtung nachgeordnet eine weitere entsprechende Strecke, die einen Schleifbereich bildet, in dem die Schleifköpfe in entgegen gesetzter Richtung quer zur Förderrichtung über das Werkstück geführt werden.The grinding device is preferably wider than the maximum workpiece width, based on the conveying direction formed. In particular, the grinding region in which the grinding elements on the workpiece surface are effective can be formed by a rectilinear path on which the grinding heads are transported perpendicular to the conveying direction over the surface of the workpiece and thereby process the workpiece surface by the rotational movement. Since the grinding heads are driven in rotation, arises in the conveying direction downstream another appropriate route that forms a grinding area in which the grinding heads in opposite direction are guided transversely to the conveying direction over the workpiece.

Selbstverständlich ist es möglich, abgewinkelte geradlinige Schleifbereiche vorzusehen oder beispielsweise einen Schleifbereich mit einer dreieckförmigen Transportstrecke der Schleifköpfe auszubilden.Of course, it is possible to provide angled rectilinear grinding areas or, for example, to form a grinding area with a triangular transport path of the grinding heads.

Die beschriebene Schleifeinrichtung kann eine Schleifstation einer Schleifmaschine mit mehreren, d. h. wenigstens zwei, Schleifstationen bilden. Die weitere(n) Schleifstation(en) kann (können) mit anderen Schleifelementen, beispielsweise als Bandschleifaggregat, ausgeführt sein, um unterschiedliche Schleifbearbeitungen der Werkstückoberfläche zu ermöglichen. Die Schleifstationen sind daher vorzugsweise modular aufgebaut, sodass sie auswechselbar und in unterschiedlichen Reihenfolgen aufbaubar sind.The described grinding device can form a grinding station of a grinding machine with a plurality, ie at least two, grinding stations. The further grinding station (s) may be embodied with other grinding elements, for example as a belt grinding unit, in order to allow different grinding operations on the workpiece surface. The grinding stations are therefore preferably of modular construction, so that they can be built interchangeable and in different orders.

Figur 1 lässt eine Schleifeinrichtung erkennen, in der eine Transportkette 1 als Transporteinrichtung endlos umläuft und um zwei Umlenkräder 2 am Ende eines geradlinigen Kettenabschnitts 3 umgelenkt wird. Auf diese Weise entstehen zwei geradlinige Kettenabschnitte 3, die senkrecht zu einer Förderrichtung eines unter der Schleifeinrichtung hindurch geförderten Werkstücks ausgerichtet sind. An der Transportkette 1 sind Schleifaggregate 4 mittels eines Gehäusefußes 5 befestigt, der bezüglich der umlaufenden Kette 1 außen an der Kette befestigt ist. Das gegenüberliegende Ende des Gehäusefußes 5 ist mit einer Rolle 6 versehen, die in einer parallel zur Kette 1 umlaufenden Stützschiene 7 geführt ist. FIG. 1 allows to recognize a grinding device in which a transport chain 1 rotates endlessly as a transport device and is deflected by two deflecting wheels 2 at the end of a rectilinear chain section 3. In this way, two straight chain sections 3, which are aligned perpendicular to a conveying direction of a conveyed under the grinding device through workpiece. On the transport chain 1 grinding units 4 are fixed by means of a housing foot 5, which is fixed with respect to the circulating chain 1 outside of the chain. The opposite end of the housing base 5 is provided with a roller 6, which is guided in a parallel to the chain 1 circumferential support rail 7.

Das Schleifaggregat 4 weist in dem dargestellten Ausführungsbeispiel Schleifelemente 8 auf, die durch Bürsten mit nach unten (gegen die Oberfläche des Werkstücks) gerichteten Borsten gebildet sind und in Draufsicht einen kreisrunden Querschnitt bilden. In entsprechender Größe sind die Schleifaggregate 4 mit jeweils einer angetriebenen Scheibe 9 in Form eines Zahnrads versehen, wobei benachbarte Schleifaggregate die zugehörige angetriebene Scheibe auf verschiedenen axialen Höhen aufweisen. Zum Antrieb der angetriebenen Scheiben 9 sind zwei umlaufende flexible Treibriemen vorgesehen, die parallel zur Kette 1 in Draufsicht innen von der Kette 1 in zwei unterschiedlichen Höhen umlaufen, und zwar mit unterschiedlicher Laufrichtung, wie dies in Figur 1 durch die Pfeile 11 angedeutet ist. Dementsprechend drehen sich benachbarte Schleifaggregate 4 in unterschiedlichen Drehrichtungen, was in Figur 1 durch die Pfeile 12 verdeutlicht ist.The grinding unit 4 has in the illustrated embodiment grinding elements 8, which are formed by brushing with downwardly directed (against the surface of the workpiece) bristles and in plan view a circular cross-section form. In a corresponding size, the grinding units 4 are each provided with a driven pulley 9 in the form of a gear, wherein adjacent grinding units have the associated driven pulley at different axial heights. To drive the driven pulleys 9, two circumferential flexible drive belts are provided which rotate parallel to the chain 1 in plan view inside of the chain 1 in two different heights, with different running direction, as in FIG. 1 indicated by the arrows 11. Accordingly, adjacent grinding units 4 rotate in different directions, which in FIG. 1 is illustrated by the arrows 12.

Für den Antrieb der Treibriemen 10 ist eine Antriebsrollenvorrichtung 13 vorgesehen, über die mit einer Spannrolle 14 ein antreibender Riemen 15 geführt ist. Vorzugsweise ist der antreibende Riemen mit einer Außenverzahnung versehen, in die eine Innenverzahnung des Treibriemens 10 eingreift, sodass dieser schlupffrei durch den antreibenden Riemen 15 angetrieben wird.For driving the drive belt 10, a drive roller device 13 is provided, over which a tensioning roller 14, a driving belt 15 is guided. Preferably, the driving belt is provided with an outer toothing, in which an internal toothing of the drive belt 10 engages, so that it is driven without slip by the driving belt 15.

Figur 2 verdeutlicht den Aufbau der Schleifaggregate 4 in einem Hochschnitt, der in Förderrichtung liegt und durch zwei Schleifaggregate 4 hindurch ausgeführt ist. FIG. 2 illustrates the structure of the grinding units 4 in a high section, which is in the conveying direction and is performed by two grinding units 4 therethrough.

Die Schleifelemente 8 der Schleifaggregate weisen jeweils einen kreisrunden Teller 16 auf, in dessen Mittelpunkte eine Achse 17 befestigt. Der Teller 16 trägt die nach unten ragenden Borsten 8', mit denen das Schleifelement 8 auf die Oberfläche eines Werkstücks einwirkt. Die Achse 17 erstreckt sich durch den Gehäusefuß 5 hindurch, indem sie mit Nadellagern 18 drehbar gelagert ist. Oberhalb des Gehäusefußes 5 ist die Achse mit einem Abstandsstück 19, 19' versehen, dessen Durchmesser wesentlich größer als der Durchmesser der Achse 17 innerhalb des Gehäusefußes 5 ist. Mit einem nach oben ragenden Ansatz 20 ist die Achse drehfest mit der angetriebenen Scheibe 9 in Form eines Zahnrades verbunden. Das an seinem Umfang mit Zähnen ausgebildete Zahnrad 9 kämmt mit dem umlaufend angetriebenen zugehörigen Treibriemen 10, von denen zwei in unterschiedlichen Höhen umlaufen. Die Achsen mit dem längeren Abstandsstück 19 weisen mit dem oberen Treibriemen 10 kämmende Zahnräder 9 auf, während die Zahnräder 9 der Achsen mit dem kürzeren Abstandsstück 19' mit dem unten umlaufenden Treibriemen kämmen.The grinding elements 8 of the grinding units each have a circular plate 16, in the center of an axis 17 attached. The plate 16 carries the downwardly projecting bristles 8 ', with which the grinding element 8 acts on the surface of a workpiece. The axis 17 extends through the housing base 5 by being rotatably supported by needle bearings 18. Above the housing base 5, the axis is provided with a spacer 19, 19 ', whose diameter is substantially larger than the diameter of the axis 17 within the housing base 5. With an upwardly projecting lug 20, the axis is rotatably connected to the driven pulley 9 in the form of a gear. The formed at its periphery with teeth gear 9 meshes with the circumferentially driven associated drive belt 10, two of which rotate at different heights. The axles with the longer spacer 19 have intermeshing gears 9 with the upper drive belt 10, while the gears 9 of the axles with the shorter spacer 19 'mesh with the bottom circulating drive belt.

Figur 2 lässt noch erkennen, dass die umlaufende Stützschiene 7 ortsfest in einem Maschinengestell 21 gelagert ist und dass die Rollen 6 der Schleifaggregate 4 in der Stützschiene 7 formschlüssig geführt sind. FIG. 2 can still be seen that the circumferential support rail 7 is fixedly mounted in a machine frame 21 and that the rollers 6 of the grinding units 4 are guided positively in the support rail 7.

Figur 2 lässt ferner erkennen, dass die Gerätefüße 5 der Schleifaggregate 8 fest mit den Gliedern der Kette 1 verbunden sind und dass die Kette 1 über ein Umlenkrad 2 umgelenkt ist. Oberhalb des Umlenkrads 2 sind in Figur 2 (nicht angetriebene) Umlenkrollen 22 für die Treibriemen 10 dargestellt. FIG. 2 shows further that the device feet 5 of the grinding units 8 are firmly connected to the links of the chain 1 and that the chain 1 is deflected by a deflection wheel 2. Above the guide wheel 2 are in FIG. 2 (non-driven) pulleys 22 for the drive belt 10 shown.

Figur 3 lässt erkennen, dass eine der Umlenkrollen 2 für die Transportkette 1 durch einen Elektromotor 23 angetrieben ist. Oberhalb der angetriebenen Umlenkrolle 2 sind auch hier (nicht angetriebene) Umlenkrollen 22 für die Treibriemen 10 gelagert. FIG. 3 indicates that one of the pulleys 2 for the transport chain 1 is driven by an electric motor 23. Above the driven deflection roller 2 (not driven) deflection rollers 22 are also stored for the drive belt 10 here.

Figur 4 verdeutlicht in vergrößerter Darstellung insbesondere die Antriebsrollenanordnung 13, über die der antreibende Riemen 15 für den Treibriemen 10 geführt ist, wobei der Treibriemen 10 beidseitig gezahnt ausgebildet ist. FIG. 4 illustrates in an enlarged view in particular the drive roller assembly 13 through which the driving belt 15 is guided for the drive belt 10, wherein the drive belt 10 is formed on both sides serrated.

Figur 5 verdeutlicht eine andere Ausführungsform für den Antrieb der Schleifelemente 8. In dieser Ausführungsform sitzt die angetriebene Scheibe in Form des Zahnrads 9' nicht auf der Achse 17, sondern ist über eine Treibriemenverbindung 23 mit der Achse verbunden. Das Zahnrad 9' ist an einem Schwenkhebel gelagert, der in Richtung des in Figur 5 eingezeichneten Doppelpfeils schwenkbar ist. Unter Belastung einer (nicht dargestellten) Feder wird der Schwenkhebel gegen den zugehörigen Treibriemen 10, der auch hier doppelverzahnt ausgebildet ist, gedrückt. Die Anordnung mit dem federbelasteten Schwenkhebel hat den Vorteil, dass ein sicherer und schlupffreier Antrieb des Zahnrads 9' auch dann gewährleistet ist, wenn sich der Treibriemen 10 etwas im Gebrauch längen sollte und daher dazu neigen könnte, nach innen, d. h. von dem Zahnrad 9, 9' weg, nach zu geben. Um dies zu verhindern, ist im Übrigen entlang den geradlinigen Kettenabschnitten, an denen sich die Antriebsrollenanordnung 13 nicht befindet, der Treibriemen 10 durch eine lineare Führung 25 unterstützt. Diese lineare Führung 25 ist auch in dem Ausführungsbeispiel gemäß den Figuren 1 bis 4 enthalten. FIG. 5 illustrates another embodiment for the drive of the grinding elements 8. In this embodiment, the driven disc sits in the form of the gear 9 'not on the axis 17, but is connected via a drive belt connection 23 with the axis. The gear 9 'is mounted on a pivot lever, which in the direction of in FIG. 5 drawn double arrow is pivotable. Under load of a spring (not shown), the pivot lever against the associated drive belt 10, which is also formed here double-toothed pressed. The arrangement with the spring-loaded pivot lever has the advantage that a safe and slip-free drive of the gear 9 'is ensured even if the drive belt 10 should be slightly longer in use and therefore could tend to inward, ie from the gear 9, 9 'away to give. Incidentally, in order to prevent this, the drive belt 10 is supported by a linear guide 25 along the rectilinear chain portions where the drive roller assembly 13 is not located. This linear guide 25 is also in the embodiment according to the FIGS. 1 to 4 contain.
