Description

Zum Bearbeiten ebener Flächen, z. B. Bohnern, Schleifen und Polieren von Fußböden o. dgl., werden fast ausschließlich Vorrichtungen benutzt, bei denen entweder um ihre Achse waagerecht kreisende Scheiben, besetzt mit Schleifsteinen, Bürsten o. dgl., als Werkzeug dienen oder mit Schleifmitteln versehene, um zwei waagerecht kreisende Scheiben laufende endlose Bänder vorgesehen sind.For processing flat surfaces, e.g. B. floor polishing, sanding and polishing o. The like., Devices are used almost exclusively in which either their Discs rotating horizontally on the axis, fitted with grindstones, brushes or the like, as a tool serve or provided with abrasives, around two horizontally rotating disks are provided endless belts.

Beide Vorrichtungen haben den Nachteil, daß sie in den verschiedenen Schleifbereichen ungleichmäßig wirken. Bei den Schleifscheiben nimmt die Wirkung vom Rande zur Achse gleichmäßig ab. Das umlaufende Band arbeitet teilweise in gerader Linie, teilweise im Kreise und läßt dabei alle zwischenliegenden Bereiche frei. Es bleibt also der Achtsamkeit und Geschicklichkeit des Arbeiters überlassen, inwieweit er alle Teile der zu bearbeitenden Fläche gleichmäßig erfaßt.Both devices have the disadvantage that they are in the different grinding areas appear uneven. With the grinding wheels, the effect increases from the edge to the axis evenly. The revolving belt works partly in a straight line, partly in a circle, leaving all areas in between free. So it remains to be mindful and leave to the skill of the worker to what extent he grips evenly all parts of the surface to be worked.

Die neue Erfindung vermeidet diese Nachteile. Alle Punkte der Bonner-, Polier- oder Schleifscheibe machen genau die gleiche Bewegung in der Ebene entweder im Kreise, in einer Ellipse oder in einer Geraden. Jeder Punlit bewegt sich parallel zu allen andern,. Somit ist die Wirkung überall die gleiche. Die Bewegung entspricht genau dem bekannten Handpolieren, das auch heute noch bei der Ausführung feiner Holzarbeiten fast ausschließlich angewendet wird.The new invention avoids these disadvantages. All points of the Bonner, Polier or Grinding wheel make exactly the same movement in the plane either in a circle, in an ellipse or in a straight line. Each point moves parallel to all the others. So the effect is the same everywhere. The movement corresponds exactly to the known Hand polishing, which is still almost exclusively used today for fine woodwork is applied.

Nach dem Erfindungsgedanken kann die Schleifscheibe beliebig vieleckig oder rund sein. Zum Erzeugen der Bewegung werden zweckmäßig in bekannter Weise die Kräfte einer oder mehrerer mit außermittigem Schwerpunkt waagerecht kreisenden Wuchtmassen benutzt, die an der Schleifscheibe gelagert sind. Wenn nur eine Wuchtmas.se kreist, so wird dadurch beim Werkzeug eine kreisende Bewegung erzielt, wobei der Kreisdurchmesser bestimmt wird durch das Eigengewicht der Schleifscheibe im Verhältnis zum Wuchtgewicht und Schwerpunktsabstand. Es kann somit durch einfaches Verändern des Wuchtgewichtes oder des Schwerpunktabstandes die Arbeitsbewegung der Schleifscheibe abgeändert werden. Soll das Werkzeug eine geradlinige Bewegung erhalten, werden zwei in gleicher Ebene waagerecht entgegengesetzt synchron kreisende Wuchtmassen benutzt. Zum Erzeugen von ellipsenähnlichen Bewegungen sind ebenfalls zwei Wuchtscheiben notwendig, die entweder mit gegeneinander versetzten Wuchtmassen arbeiten oder deren Wuchtmassen verschieden schwer sind oder deren Schwerpunktsabstand verschieden ist. In manchen Fällen werden besondere Wirkungen dadurch hervorgerufen, daß die verschiedenen Schwungmassen mit verschiedener Winkelgeschwindigkeit kreisen.According to the idea of the invention, the grinding wheel can be polygonal or round as desired be. To generate the movement, the forces of one or more with an eccentric center of gravity are expediently used in a known manner horizontally rotating balancing masses are used, which are mounted on the grinding wheel. If only one balancing act is circling, so a circular movement is thereby achieved with the tool, whereby the circle diameter is determined by the weight of the grinding wheel in relation to the balancing weight and center of gravity distance. It can be done by simply changing the balancing weight or the distance from the center of gravity, the working movement of the grinding wheel can be modified. Should the tool be a straight line Movement received, two in the same plane horizontally opposite and synchronously circling balancing masses are used. To generate movements similar to ellipses, two balancing disks are also necessary, either with one another offset balancing masses work or whose balancing masses are of different weight or whose center of gravity is different. In some cases it will have special effects caused by the fact that the various centrifugal masses revolve at different angular velocities.

Die kreisenden Massen werden am besten eingekapselt, wobei die Schleifmittel als Werkzeug am Boden der Kapsel befestigt sind. Auf der Kapsel kann der Antriebsmotor mit oder ohne Zwischengetriebe angeordnet sein, soThe orbiting masses are best encapsulated using the abrasive as a tool are attached to the bottom of the capsule. The drive motor can be on the capsule with or be arranged without an intermediate gear, so

daß die Vorrichtung eine in sich geschlossene Einheit bildet, die als Ganzes die Schleifbewegungen mitmacht und dabei gleichzeitig als Belastung dient. Der Antrieb kann aber auch.', vom getrennt angeordneten Motor über eine '■ bewegliche Welle erfolgen. Die Schleifvorrichtung wird in üblicher Weise entweder mit einem Gerätstiel geführt oder: ist an einem ortsfesten Halter befestigt. In beiden Fällenthat the device forms a self-contained unit, which as a whole participates in the grinding movements and at the same time serves as a load. The drive can, however, also take place from the separately arranged motor via a movable shaft. The grinding device is usually guided either with a tool handle or : is attached to a stationary holder. In both cases

ίο ist es notwendig, zwischen Gerätstiel oder Halter und Vorrichtung ein federndes Zwischenmittel einzuschalten, 'damit die Hand oder der Halter nicht oder nur in geringem Maße von der Bewegung des Werkzeuges in Mitleidenschaft gezogen werden.ίο it is necessary between the device handle or Holder and device insert a resilient intermediate means, so that the hand or the holder does not or only to a small extent from the movement of the tool in Be drawn to it.

Im Ausführungsbeispiel des Gegenstandes der Erfindung zeigen Abb. 1 und 2 eine solche Vorrichtung mit oben auf der Kapselt angeordnetem Motorm und mit einem Gerätstiel/. In the exemplary embodiment of the subject matter of the invention, FIGS. 1 and 2 show such a device with a motor m arranged on top of the capsule and with a device handle /.

Dieser Gerätstiel umfaßt durch, eine Gabel g die Kapsel k und ist mit ihr durch die Federn e verbunden. Die Kapselt trägt am Boden die Schleifmittels. Aus Abb. 2 ist die Anordnung einer Wuchtmasse w für Kreisbewegungen des Werkzeuges ersichtlich, aus den Abb. 3, 4 und 5 die schematische Anordnung zweier Wuchtmassen für Ellipsen- oder geradlinige Bewegungen. In Abb. 3 ist die Wuchtmassenstellung für geradlinige Bewegungen, in Abb. 4 ; und 5 für Ellipsenbewegungen, von oben ge-'vSehen, dargestellt, wobei Abb. 4 versetzte /iWüchtmassen und Abb. 5 verschiedene Schwer-•'p/uaktsabstände aufweisen.This device handle includes a fork g, the capsule k and is connected to her by the springs e . The capsule carries the abrasive on the bottom. From Fig. 2 the arrangement of a balancing mass w for circular movements of the tool can be seen, from Figs. 3, 4 and 5 the schematic arrangement of two balancing masses for elliptical or linear movements. In Fig. 3 is the balancing mass position for straight movements, in Fig. 4 ; and 5 for elliptical movements, seen from above, with Fig. 4 showing offset / imbalanced masses and Fig. 5 different gravity distances.
