Description

Die vorliegende Erfindung bezieht sich auf eine Vibrationsgleitschleifmaschine, mit einem Behälter zur Aufnahme des Schüttgutes und einem Vibrationsantrieb. Solche Maschinen sind bekannt, beispielsweise aus der CH-A 458 103 und CH-A 511 675. Solche Maschinen weisen eine Vibratormulde auf, in welcher das Schüttgut, d.h. das zu bearbeitende Stückgut zusammen mit festem Trägermaterial und eventuellen Zusatzmitteln vibriert werden, um das Stückgut zu entgraten, glätten, schleifen und polieren. Ausserdem weist diese Maschine eine Ablassvorrichtung auf, die an der Seitenwand des Behälters angeordnet ist. Diese Ablassvorrichtung weist unter anderem einen Zapfen auf, der herausgeschraubt werden muss, falls man den Behälter entleeren will. Die genaue Einpassung dieses Zapfens an die gekrümmte Behälterwand ist recht schwierig und kostspielig, denn bei kleinsten Unebenheiten ist die Gefahr gross, dass kleines Stückgut daran hängen bleibt und verletzt wird. Ausserdem ist eine schnelle und vollständige Entleerung einer Kammer mit Kern schwierig durchzuführen. Andererseits ist es zur Erzielung einer wirksamen Bearbeitung von grossem Vorteil, dass der Behälter einen Kern aufweist und somit eine ringförmige Schleifkammer entsteht, in welcher das Schüttgut spiralförmig um den Kern bewegt wird.The present invention relates to a vibratory vibratory grinding machine with a container for receiving the bulk material and a vibratory drive. Such machines are known, for example from CH-A 458 103 and CH-A 511 675. Such machines have a vibrator trough in which the bulk material, i.e. The piece goods to be processed are vibrated together with solid carrier material and any additives in order to deburr, smooth, grind and polish the piece goods. In addition, this machine has a drain device which is arranged on the side wall of the container. This drain device has, among other things, a pin that has to be unscrewed if one wants to empty the container. The exact fitting of this pin on the curved container wall is quite difficult and expensive, because with the smallest unevenness there is a great risk that small piece goods get caught on it and get injured. In addition, rapid and complete emptying of a chamber with a core is difficult to carry out. On the other hand, to achieve effective processing, it is of great advantage that the container has a core and thus an annular grinding chamber is created in which the bulk material is moved spirally around the core.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung eine Vibrationsgleitschleifmaschine anzugeben, die eine wirksame Entleerung des Behälters gestattet und andererseits die Verletzungsgefahr von kleinem, empfindlichem Stückgut beseitigt. Eine solche Maschine wird in den Ansprüchen beschrieben.In contrast, it is an object of the present invention to provide a vibratory vibratory grinding machine which allows an effective emptying of the container and on the other hand eliminates the risk of injury to small, sensitive piece goods. Such a machine is described in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert, wobei Figur 1 im Schnitt einen Behälter einer erfindungsgemässen Maschine und Figur 2 eine Ausführungsvariante darstellt.The invention is explained in more detail below with reference to a drawing of exemplary embodiments, with FIG. 1 showing in section a container of a machine according to the invention and FIG. 2 an embodiment variant.

Figur 1 zeigt einen Behälter 1 und einen aus den oben zitierten Patentschriften bekannten Vibrationsantrieb 2. Der Behälter weist einen kernlosen Boden 3, der in vorliegendem Beispiel in der Mitte, das heisst bei der Ablassvorrichtung, leicht konkav ist, aber auch stärker konkav (siehe 3'), eben oder konvex sein kann, sowie einen beispielsweise an seinem Umfang mittels eines Gewindes 4 schraubbaren Deckel 5 mit Griffen 6 auf. Der Deckel 5 besitzt einen umlaufenden Wulst 7 mit abgerundeter Innenfläche 8.FIG. 1 shows a container 1 and a vibration drive 2 known from the patents cited above. The container has a coreless base 3 which, in the present example, is slightly concave in the middle, that is to say with the drainage device, but also more concave (see FIG. 3 '), may be flat or convex, and a cover 5 with handles 6, for example screwable on its circumference by means of a thread 4. The cover 5 has a circumferential bead 7 with a rounded inner surface 8.

Im Mittelbereich des Bodens 3 befindet sich ein Kernmantel 10, beispielsweise aus einem abreibarmen Kunststoff. Der Kernmantel 10 weist Mittel zum Abbremsen des Schüttgutes auf, wobei diese Mittel hier nicht eingezeichnet sind, sondern in einer parallelen Anmeldung (EP-A 0 225 417) des gleichen Anmelders. In dieser Anmeldung ist beschrieben, dass diese Mittel aus in Umfangrichtung laufenden Rippen oder radialen Rippen oder flügelähnlichen, radialen Rippen bestehen können oder dass der Kernmantel konkav gestaltet ist und ausserdem, dass auch die Seitenwände und der Deckel eine andere Gestalt aufweisen können. In vorliegendem Beispiel wird der Kernmantel von einer zylindrischen Zentrumsnabe 11 mit Spiel gehalten, die hohl ist und auch als Wassereinlass 12 oder als Einlass für Zusatzmittel dient. Der Wassereinlass ist mit einem Spülwasseranschluss 13 verbunden, der durch den Deckel 5 geführt ist. Es ist aber auch möglich, den Deckel mittels einer Halterung zu befestigen, wie dies in der erwähnten parallelen Patentanmeldung beschrieben ist. Wichtig ist, dass der Kernmantel weitgehend unabhängig vom Behälter ist und somit dessen Vibrationen nicht oder nur stark gedämpft ausführt. Da der Kernmantel sich bei der Spülung vom Boden abhebt, kann das Spülwasser am Behälterboden austreten. Desgleichen kann auch Druckluft in das Innere des Kernmantels geleitet werden. Der Kernmantel 10 erlaubt es, die Ablassvorrichtung 14 in der Mitte des Bodens 3 anzuordnen, das heisst unter dem Kernmantel. Das Anpassen des Verschlusszapfens 15 ist nicht nötig wie im vorbekannten Beispiel und kann derart ausgeführt sein, dass auch kleines und empfindliches Stückgut nicht an die Übergangsstelle zwischen dem Behälterboden und dem Zapfen anstossen, wodurch die Verletzungsgefahr beseitigt wird. Der Verschlusszapfen 15 wird über einen schematisch dargestellten Verstellmechanismus 16 auf und ab bewegt, wobei selbstverständlich weitere Verstellmechanismen in Frage kommen und der Verschlusszapfen beispielsweise gekippt oder in den Behälterboden zurückgezogen werden kann. Die Anordnung der Ablassvorrichtung im Behälterboden ermöglicht eine einfache und wirksame Entleerung des Schüttgutes. Dadurch wird es möglich, das gesamte Schüttgut über eine Führung 17 in eine fahrbare Auffangvorrichtung aufzufangen und aufzuarbeiten, währenddessen die Maschine, beziehungsweise deren Behälter, schnell gereinigt und wieder geladen werden kann. Ein derartiger Behälter eignet sich für das automatische Beschicken und insbesondere automatische Entleeren von Vibrationsgleitschleifmaschinen und erlaubt einen wesentlich gesteigerten Wirkungsgrad.In the central region of the bottom 3 there is a core jacket 10, for example made of a low-abrasion plastic. The core jacket 10 has means for braking the bulk material, these means not being shown here, but in a parallel application (EP-A 0 225 417) by the same applicant. In this application it is described that these means can consist of ribs running in the circumferential direction or radial ribs or wing-like, radial ribs or that the core jacket is of concave design and also that the side walls and the cover can also have a different shape. In the present example, the core casing is held with play by a cylindrical center hub 11, which is hollow and also serves as a water inlet 12 or as an inlet for additives. The water inlet is connected to a rinse water connection 13 which is guided through the cover 5. However, it is also possible to fasten the lid by means of a holder, as is described in the parallel patent application mentioned. It is important that the core jacket is largely independent of the container and therefore does not vibrate or only dampens it to a great extent. Since the kernmantle lifts off the floor during rinsing, the rinsing water can escape from the bottom of the tank. Likewise, compressed air can also be conducted into the interior of the core jacket. The core jacket 10 allows the drain device 14 to be arranged in the middle of the bottom 3, that is to say under the core jacket. The adjustment of the locking pin 15 is not necessary as in the previously known example and can be carried out in such a way that even small and sensitive piece goods do not hit the transition point between the container bottom and the pin, thereby eliminating the risk of injury. The locking pin 15 is moved up and down by means of a schematically illustrated adjustment mechanism 16, whereby of course further adjustment mechanisms come into question and the locking pin can for example be tilted or retracted into the container bottom. The arrangement of the drain device in the bottom of the container enables simple and effective emptying of the bulk material. This makes it possible to collect and process the entire bulk material via a guide 17 in a mobile collecting device, during which the machine or its container can be quickly cleaned and loaded again. Such a container is suitable for the automatic loading and in particular automatic emptying of vibratory vibratory grinding machines and allows a significantly increased efficiency.

In der Ausführungsvariante gemäss Figur 2 werden die Zusatzmittel nicht über den Wassereinlass, sondern über eine gegenüber der Mitte versetzten Öffnung 9 mit Schraubkappe beigegeben. An der Behälterwand ist oben ein Überlauf 18 angebracht, um den bei der Bearbeitung entstehenden Schaum abzulassen. In diesem Beispiel wird ferner der Verschlusszapfen 19 nicht von unten oder von der Seite, sondern von oben betätigt. Zu diesem Zwecke besteht die Zentrumsnabe 20 aus einem ersten Stück 21, in dem der Spülwasserauslass 12 angeordnet ist, gefolgt von einem Rohr 22, an dem der Verschluss 19 angebracht ist. Es ist wie in der Parallelanmeldung möglich, den Kernmantel verschiebbar zu befestigen, wodurch eine exzentrische Anordnung möglich ist, sowie den Kernmantel gegensinnig zu den Schwingungen des Behälters zu bewegen. Ausserdem kann die Zentrumsnabe mit der Wasserdurchführung exzentrisch angeordnet sein, so dass der Kernmantel durch Drehung derart verschoben werden kann, dass der Querschnitt der Schleifkammer veränderbar ist. Die Ablassvorrichtung kann ebenfalls versetzt angeordnet werden, wobei dann der Bodenteil an diesem Ort entsprechend konkav, konvex oder eben gestaltet und der Kernmantel darüber, das heisst ebenfalls versetzt, angeordnet wird.In the embodiment variant according to FIG. 2, the additives are not added via the water inlet, but rather via an opening 9 with a screw cap offset relative to the center. An overflow 18 is attached to the top of the container wall in order to drain off the foam formed during processing. In this example, the locking pin 19 is also actuated not from below or from the side, but from above. For this purpose, the center hub 20 consists of a first piece 21 in which the flushing water outlet 12 is arranged, followed by a tube 22 to which the closure 19 is attached. As in the parallel application, it is possible to fasten the core jacket so that it can be eccentrically arranged, and to move the core jacket in the opposite direction to the vibrations of the container. In addition, the center hub with the water feedthrough can be arranged eccentrically, so that the core jacket can be displaced by rotation in such a way that the cross section of the grinding chamber can be changed. The drain device can also be arranged offset, in which case the base part is designed to be concave, convex or flat at this location and the core jacket is arranged above it, that is to say also offset.
