Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur mechanisch abrasiven oder polierenden Bearbeitung der Oberflächen und/oder Kanten und/oder Stirnflächen von plattenförmigen Werkstücken nach dem Oberbegriff von Anspruch 1.The present invention relates to a device for mechanically abrasive or polishing machining of the Surfaces and / or edges and / or end faces of plate-shaped workpieces according to the generic term of Claim 1.

Für die Bearbeitung von Oberflächen und Kanten von plattenförmigen Werkstücken sind eine Reihe von Vorrichtungen bekannt. Dabei handelt es sich entweder um manuell zu bedienende maschinengetriebene Handapparate wie beispielsweise Schleifmaschinen oder um automatische, gesteuerte Maschinen welche beispielsweise in Fertigungsstrassen integriert sind.For processing surfaces and edges of plate-shaped workpieces are a series of Devices known. This is either manually operated machine-operated handsets such as for example grinding machines or automatic, controlled machines which, for example, in Production lines are integrated.

So sind beispielsweise Entgratungsvorrichtungen resp. - maschinen bekannt, welche für das automatisierte Entgraten von genippelten, gelaserten, mit Wasserstrahl geschnittenen oder gestanzten Bleche aus Stahl oder Nichteisenmetallen eingesetzt werden. Dabei werden die zu bearbeitenden Werkstücke resp. Bleche auf ein Transportband aufgelegt, welches in der Regel als Endlos-Band ausgebildet ist. Die Fixierung der Bleche erfolgt beispielsweise magnetisch durch unter dem Transportband angeordneten Magnetplatten und/oder durch Vakuumbildung. Das Transportband führt dann die Bleche unter ein Bearbeitungswerkzeug, welches beispielsweise einen tellerförmigen Schleif- oder Poliereinsatz aufweist, welcher um seine im wesentlichen senkrecht zum Blech stehende Achse angetrieben ist. For example, deburring devices, respectively. - machines known for automated deburring of nippled, lasered, water jet cut or stamped sheets of steel or non-ferrous metals be used. The ones to be processed Workpieces resp. Sheets placed on a conveyor belt, which is usually designed as an endless belt. The The sheets are fixed magnetically, for example by magnetic plates arranged under the conveyor belt and / or by vacuum formation. The conveyor belt then leads the sheets under a processing tool, which for example a plate-shaped grinding or Has polishing insert, which around its essentially Axis perpendicular to the sheet is driven.

Die mögliche Bearbeitungsbreite ist dabei durch den Durchmesser des Bearbeitungswerkzeuges vorgegeben. Da die Werkzeuge nicht beliebig gross ausgeführt werden können, ist auch die mögliche Bearbeitungsbreite eingeschränkt.The possible processing width is determined by the Diameter of the machining tool specified. Since the Tools cannot be made arbitrarily large, the possible processing width is also limited.

Um eine möglichst homogene Bearbeitungswirkung zu erzielen, ist die Anordnung von mehreren tellerförmigen Schleif- resp. Poliereinsätzen in einem einzelnen, ebenfalls rotierbar angetriebenen Werkzeugkopf bekannt. Dabei sind diese Schleif- resp. Poliereinsätze symmetrisch bezüglich der Drehachse des Werkzeugkopfes angeordnet, wobei sowohl die Schleif- resp. Poliereinsätze um ihre Achsen angetrieben sind, wie auch der Werkzeugkopfes selbst drehbar angetrieben sind. Diese Drehbewegungen können entweder direkt über ein Getriebe gekoppelt sein oder unabhängig voneinander separat angesteuert sein. Diese Konstruktion liefert sehr gute Entgratungsresultate, ist aber aufgrund ihres aufwendigen Aufbaus nur in beschränkten Dimensionen, d.h. nur bis zu einem beschränkten Durchmesser, ausführbar. Bei sehr grossen Durchmessern wird der Werkzeugkopf sehr schwer, was einen entsprechend gross dimensionierten Maschinenträger bedingt.In order to achieve the most homogeneous processing effect possible, is the arrangement of several plate-shaped grinding or Polishing inserts in a single, too known rotatably driven tool head. Are there this grinding or Polishing inserts symmetrical with respect arranged the axis of rotation of the tool head, both the grinding or Polishing inserts around their axes are driven, as is the tool head itself are rotatably driven. These rotations can either be coupled directly via a transmission or can be controlled separately. This Construction gives very good deburring results but due to their complex structure only in limited Dimensions, i.e. only up to a limited Diameter, executable. With very large diameters the tool head is very heavy, which makes it correspondingly large dimensioned machine carrier conditional.

Weiter sind Vorrichtungen bekannt, bei welchem die Oberfläche von walzenartigen Werkzeugen bearbeitet werden. Die Achsen dieser Werkzeuge verlaufen im wesentlichen parallel und senkrecht zur Werkstückebene resp. Werkstückbewegungsrichtung. Für das Entgraten von plattenförmigen Werkstücken wie Bleche sind derartige Werkzeuge allerdings nur sehr bedingt tauglich, da sie Kantenflächen, welche senkrecht zur Werkzeugachse verlaufen, nur sehr schlecht bearbeiten können. Devices are also known in which the Surface can be processed by roller-like tools. The axes of these tools run essentially parallel and perpendicular to the workpiece plane respectively. Workpiece movement direction. For deburring plate-shaped workpieces such as sheets are such However, tools are only suitable to a limited extent, since they Edge surfaces that are perpendicular to the tool axis run, can only work very poorly.

Generell besteht ein Problem bei der automatisierten Bearbeitung von plattenförmigen Werkstücken, indem insbesondere die mechanischen Oberflächenbearbeitungsverfahren im Gegensatz zu den übrigen Produktionsschritten langsam sind, d.h. eine kleinere Durchsatzleistung aufweisen als die übrigen Komponenten der Produktionsvorrichtungen. Wenn nun all diese Vorrichtungen in einer Produktionsstrasse zusammengefasst sind, führt dies zu einer beschränkten Produktionsleistung.Generally there is a problem with automated Processing of plate-shaped workpieces by especially the mechanical ones Surface processing methods in contrast to the other production steps are slow, i.e. a have lower throughput than the rest Components of the production devices. If all these devices in a production line are summarized, this leads to a limited Production output.

Die Aufgabe der vorliegenden Erfindung bestand nun darin, eine Bearbeitungsvorrichtung gemäss Oberbegriff zu finden, welche eine zuverlässige und rasche Bearbeitung der Oberflächen und/oder Kanten von breiten Blechen mit unterschiedlichsten Bearbeitungsflächen erlaubt.The object of the present invention was now to to find a processing device according to the preamble, which is a reliable and quick processing of the Surfaces and / or edges of wide sheets with different processing areas allowed.

Diese Aufgabe wird erfindungsgemäss durch eine Vorrichtung mit den Merkmalen von Anspruch 1 gelöst.According to the invention, this object is achieved by a device solved with the features of claim 1.

Durch die drehbare, exzentrische Anordnung wenigstens eines Werkzeuges, welches selbst ebenfalls um seine Achse drehbar angetrieben ist, kann in Abhängigkeit der Exzentrizität vorteilhafterweise eine im Vergleich zum Werkzeugdurchmesser vielfache Bearbeitungsbreite erreicht werden und damit die Bearbeitungszeit für derartige Werkstücke verkürzt werden. Gleichzeitig werden alle zu bearbeitenden Flächen und/oder Kanten optimal durch das Werkzeug erfasst resp. bearbeitet.Due to the rotatable, eccentric arrangement of at least one Tool, which itself can also be rotated about its axis is driven, depending on the eccentricity advantageously a compared to Tool diameter multiple machining width reached and thus the processing time for such Workpieces can be shortened. At the same time, everyone becomes too machining surfaces and / or edges optimally through the Tool recorded or processed.

Weitere, bevorzugte Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen 2 bis 6.Further, preferred embodiments of the invention result themselves from the dependent claims 2 to 6.

Gerade die Anordnung von mehreren, verschiedenen Werzeugen, welche durch die Höhenverstellung jeweils nacheinander zum Einsatz kommen, kann vorteilhafterweise eine optimale Bearbeitung mit einer einzigen Vorrichtung in einem einzigen Durchlauf des zu bearbeitenden Werkstückes erfolgen. Diese Anordnung lässt auch die Bearbeitung unterschiedlicher Werkstücke mit derselben Vorrichtung zu, ohne dass grosse oder umständliche Umrüstarbeiten erfolgen müssten oder gar mehrere verschiedene Maschinen eingesetzt werden müssten.Just the arrangement of several different tools, which one after the other through the height adjustment Use can advantageously be optimal Machining with a single device in one single pass of the workpiece to be machined respectively. This arrangement also leaves editing different workpieces with the same device, without large or cumbersome retrofitting work would have to be used or even several different machines would have to be.

Vorteilhafterweise kann eine derartige Vorrichtung neben beispielweise einer Entgratungsfunktion gleichzeitig resp. anschliessend auch eine Oberflächenbearbeitungsfunktion übernehmen, entsprechend den eingesetzten Werkzeugtypen.Such a device can advantageously be used in addition to For example, a deburring function at the same time. then also a surface processing function take over, according to the used tool types.

    • In Figur 1 ist die Seitenansicht einer erfindungsgemässen Vorrichtung beispielsweise zum Entgraten und Polieren von beispielsweise gestanzten oder geschnittenen Blechen 1 dargestellt. Diese Bleche 1, welche unterschiedliche Abmessungen aufweisen können und beispielsweise ein Anzahl von ausgestanzten oder geschnittenen Öffnungen in der Oberfläche aufweisen, werden auf ein endlos umlaufendes Transportband 2 der Vorrichtung aufgelegt. Diese Blechteile 1 werden beispielsweise mittels einer Vakuumvorrichtung auf dem Transportband 2 gehalten, oder im Falle von Eisenblechteilen durch eine oder mehrere, unterhalb des Bandes 1 im Bereich des Bearbeitungswerkzeuges 3 angeordnete Magnetplatten (nicht dargestellt). Das Transportband 2 fördert nun diese Blechteile 1 unter dem Bearbeitungswerkzeug 3 hindurch, welches beispielsweise in Form eines Schleiftellers ausgebildet ist. Als Bearbeitungswerkzeug 3 kommen alle Arten von bekannten Oberflächenbearbeitungswerkzeugen wie beispielsweise Bürstenteller, Schleifteller, Lamellenteller etc. zur Anwendung, entsprechend dem zu erreichenden Bearbeitungsresultat. Das Bearbeitungswerkzeug 3 ist nun an einem Arm 5 bezüglich der Geratehauptachse 4 vorzugsweise höhenverstellbar angeordnet und weist einen Antrieb für die Eigenrotation auf. Das Bearbeitungswerkzeug 3 wird nun auf einer Kreisbahn um die Gerätehauptachse 4 herum über die gesamte Breite des Transportbandes 2 bewegt und bestreicht damit sämtliche Blechteile 1. Hierfür ist beispielsweise ein mittels eines Motors angetriebener Haltezylinder 6 vorgesehen, in welchem der Arm 5 des Bearbeitungswerkzeuges 3 gelagert resp. befestigt ist. Der Arm 5 kann vorzugsweise radial bezüglich der Gerätehauptachse 4 verstellbar ausgeführt sein, wobei die Verstellung entweder vor der Inbetriebnahme der Vorrichtung manuell ausgeführt werden kann oder während dem Betrieb automatisch gesteuert durchgeführt werden kann, beispielsweise elektrisch oder hydraulisch. Es ist klar, dass der Haltezylinder 6 nicht wie dargestellt einen kreisförmigen Querschnitt aufweisen muss, sondern auch einen vieleckigen Querschnitt aufweisen kann, d.h. nicht rund sondern eckig ausgeführt sein kann.In Figure 1 is the side view of an inventive Device for example for deburring and polishing for example stamped or cut metal sheets 1 shown. These sheets 1, which are different Can have dimensions and for example a number of punched or cut openings in the Have surface are on an endless revolving Transport belt 2 of the device placed. These sheet metal parts 1, for example, by means of a vacuum device the conveyor belt 2 held, or in the case of Sheet metal parts by one or more, below the Band 1 in the area of the machining tool 3rd arranged magnetic disks (not shown). The Conveyor belt 2 now promotes these sheet metal parts 1 under the Machining tool 3, which, for example, in Form of a grinding plate is formed. As Machining tool 3 come all kinds of known ones Surface processing tools such as Brush plates, sanding plates, lamella plates etc. for Application, according to what is to be achieved Machining result. The processing tool 3 is now on an arm 5 with respect to the main device axis 4 preferably height adjustable and has a drive for the Self rotation on. The processing tool 3 is now on a circular path around the device main axis 4 over the entire width of the conveyor belt 2 moved and brushed so all sheet metal parts 1. For example a holding cylinder 6 driven by a motor provided in which the arm 5 of the machining tool 3 stored resp. is attached. The arm 5 can preferably radially adjustable with respect to the main axis 4 of the device be carried out, the adjustment either before Commissioning of the device can be carried out manually can or controlled automatically during operation can be carried out, for example electrically or hydraulic. It is clear that the holding cylinder 6 is not have a circular cross section as shown must, but also have a polygonal cross section can, i.e. can not be round but square.

    In Figur 2 ist noch die Aufsicht der Vorrichtung nach Figur 1 dargestellt. Hier ist nun insbesondere die Kreisbahn 7 strichpunktiert dargestellt, auf welcher das Bearbeitungswerkzeug 3 um die Gerätehauptachse 4 herum bewegt wird.In Figure 2 is still the supervision of the device of Figure 1 shown. Here in particular is the circular path 7 dash-dotted lines, on which the Machining tool 3 around the main device axis 4 is moved.

    Die Gerätehauptachse 4 ist vorzugsweise in einem bezüglich des Transportbandes 2 C-förmig ausgestalteten Maschinenträger 8 gelagert, welcher beispielsweise auch den Antrieb für die Gerätehauptachse 4 resp. dem Haltzylinder 6 aufnehmen kann. Dies Anordnung hat den Vorteil, dass auch Blechteile 1 bearbeitet werden können, welche grössere Abmessungen als die Breite des Transportbandes 2 aufweisen. Derartige Blechteile 1 müssten dann beispielsweise mittels zwei Arbeitsgängen bearbeitet werden, in welchen jeweils eine Hälfte der entsprechenden Blechteile 1 bearbeitet würden.The device main axis 4 is preferably in one respect of the conveyor belt 2 C-shaped Machine carrier 8 mounted, which, for example, the Drive for the device main axis 4 resp. the holding cylinder 6 can record. This arrangement has the advantage of that too Sheet metal parts 1 can be processed, which larger Have dimensions as the width of the conveyor belt 2. Such sheet metal parts 1 would then have to be used, for example two operations are processed, in each of which processed half of the corresponding sheet metal parts 1 would.

    In Figur 3 ist nun schematisch eine alternative, erfindungsgemässe Anordnung von Bearbeitungswerkzeugen 3 in der Aufsicht dargestellt. Hier sind nun drei, bezüglich der Gerätehauptachse 4 symmetrisch angeordnete Bearbeitungswerkzeuge 3' vorgesehen. Die Bearbeitungswerkzeuge 3' sind in der Form von einer Mehrzahl von einzelnen, planetenartig um die Werkzeugachsen 9 rotierend angeordneten, rotierenden Werkzeugen 10 ausgeführt. Mit den Pfeilen sind die Bewegungsrichtungen der einzelnen Komponenten dieser Anordnung dargestellt.In Figure 3 is now an alternative, schematically Arrangement of machining tools 3 in accordance with the invention presented to the supervisory authority. Here are three of them Device main axis 4 arranged symmetrically Machining tools 3 'are provided. The Machining tools 3 'are in the form of a Plenty of individual, planet-like around the tool axes 9 rotating tools 10 executed. With the arrows are the directions of movement of the individual components of this arrangement.

    Da jedes einzelne Bearbeitungswerkzeug 3' vorzugsweise höhenverstellbar bezüglich der Gerätehauptachse 4 ausgeführt ist, können nun in den drei Bearbeitungswerkzeugen 3' jeweils verschieden wirkende Werkzeuge 10 eingesetzt werden. Damit können die Blechteile 1 in einem Transportvorgang durch das Transportband 2 mit verschiedenen Bearbeitungsmethoden behandelt werden. Since each individual machining tool 3 'is preferred height adjustable with respect to the main axis of the device 4 can now run in the three Machining tools 3 'each acting differently Tools 10 are used. So that the sheet metal parts 1 in one transport operation with the conveyor belt 2 different processing methods.

    Beispielsweise lassen sich die Blechteile 1 so in einem Arbeitsgang entgraten und polieren. Auch könne für das Entgraten in einem Arbeitsgang verschiedenartige Werkzeuge 10 eingesetzt werden, welche sich jeweils besonders für die oberen resp. seitlichen Kantenbereiche der Blechteile 1 eignen, um ein qualitativ hochstehendes Entgratresultat zu erhalten. Die jeweils einzusetzende Werkzeugart kann durch Absenken des jeweiligen Bearbeitungswerkzeuges 3' auf die Arbeitshöhe ausgewählt und aktiviert werden. Damit entfällt auch das Wechseln dieser Werkzeuge 10 resp. 3' bei herkömmlichen Vorrichtungen. Damit kann ein im Vergleich zu herkömmlichen Vorrichtungen wesentlich höherer Werkstückdurchsatz erreicht werden, was insbesondere die Anwendung in Produktionsstrassen interessant macht.For example, the sheet metal parts 1 can be made in one Deburr and polish the work step. Also for that Deburring different types of tools in one operation 10 are used, which are particularly suitable for upper resp. lateral edge areas of the sheet metal parts 1 suitable for a high quality deburring result receive. The type of tool to be used can be by Lowering of the respective processing tool 3 'on the Working height can be selected and activated. This eliminates also changing these tools 10 respectively. 3 'at conventional devices. This can be compared to conventional devices much higher Workpiece throughput can be achieved, which in particular the Application in production lines makes it interesting.

    Ein weiterer Vorteil der Höhenverstellbarkeit der einzelnen Bearbeitungswerkzeuge 3 resp. 3' liegt darin, dass die Bearbeitungshöhe dem laufenden Verschleiss der Werkzeuge 10 angepasst werden kann und damit praktisch während der gesamten Einsatzdauer der Werkzeuge 10 eine gleichbleibende Bearbeitungsqualität erzielt werden kann.Another advantage of the height adjustability of the individual Machining tools 3 resp. 3 'is that the Machining height of the ongoing wear of the tools 10 can be adjusted and therefore practical during the total service life of the tools 10 a constant Machining quality can be achieved.

    Weiter hat sich gezeigt, dass sich die erfindungsgemässe Vorrichtung nicht nur für die Bearbeitung von plattenförmigen Werkstücken aus Metall eignet, sondern ebenfalls geeignet ist für die Bearbeitung von Holz oder Kunststoffflächen.It has also been shown that the inventive Device not only for processing plate-shaped workpieces made of metal, but is also suitable for processing wood or Plastic surfaces.
