Description

Die vorliegende Erfindung bezieht sich auf eine Vibrationsgleitschleifmaschine gemäss Oberbegriff von Patentanspruch 1. Eine solche Maschine ist aus der US-A-4205 491 bekannt, wobei das zylindrische Kernstück entweder fest mit dem Behälter verbunden oder unabhängig dazu drehbar angeordnet ist und mit schräg nach unten weisenden Flügeln derart versehen ist, dass das zu bearbeitende Material nach unten gedrückt wird, um eine höhere Schleifwirkung zu erzielen.The present invention relates to a vibratory vibratory grinding machine according to the preamble of claim 1. Such a machine is known from US-A-4205 491, wherein the cylindrical core is either fixedly connected to the container or is rotatably arranged independently thereof and with obliquely pointing downwards Wing is provided such that the material to be processed is pressed down to achieve a higher grinding effect.

Während die oben beschriebenen Massnahmen geeignet sein können, um den Wirkungsgrad gegenüber dem damals bekannten Stand der Technik zu erhöhen, besteht bei kleinen und empfindlichen Teilen die Gefahr einer Verletzung insbesondere der Kernwand, die durch die nach unten drückenden Flügeln noch erhöht wird.While the measures described above can be suitable to increase the efficiency compared to the prior art known at the time, there is a risk of damage to the core wall in particular in the case of small and sensitive parts, which is further increased by the wings pressing downward.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung, eine Vibrationsgleitschleifmaschine anzugeben, bei der die Verletzungsgefahr empfindlicher, kleiner Teile behoben wird und die einen erhöhten Wirkungsgrad aufweist. Eine solche Maschine ist in den Ansprüchen beschrieben.It is an object of the present invention to provide a vibratory vibratory grinding machine in which the risk of injury to sensitive, small parts is eliminated and which has an increased efficiency. Such a machine is described in the claims.

Die Erfindung wird im folgenden anhand einer Zeichnung von Ausführungsbeispielen näher erläutert.The invention is explained below with reference to a drawing of exemplary embodiments.

Figur 8 zeigt eine zweite Ausführungsform des Behälters der erfindungsgemässen Maschine.Figure 8 shows a second embodiment of the container of the machine according to the invention.

In Figur 1 erkennt man den Behälter 1, der, in Figur 1 nicht eingezeichnet, elastisch mit einem Motor, der an jedem Ende eine Exzentermasse zur Erzeugung der Vibration aufweist, über einen Flansch verbunden ist. In diesem Ausführungsbeispiel ist der Behälter 1 auf bekannte Weise kreisringförmig gestaltet und weist eine Aussenwand 2 und einen Kern 3 auf. In diesem Behälter bewegt sich bei Vibrationen geeigneter Frequenz und Amplitude das Schüttgut in einer spiralförmigen Bahn, wie durch die Pfeile angedeutet. Der Behälter ist mit einem Deckel 4 mit Zentralverschluss 5 und Griffen 6 verschliessbar. Im Mittelteil des Zentralverschlusses befindet sich ein Wasseranschlussstutzen 7 mit dem Wassereinlass 8 im Behälterinneren. Das Wasser dient dem Reinigen des Schüttgutes und gelangt über den Auslass 9 am oberen Behälterrand wieder zum Behälter hinaus, wie dies durch die ausgezogenen Pfeile W angedeutet ist. Der Behälter wird auf bekannte Weise aus einem geeigneten Kunststoffmaterial gefertigt, während der Deckel in der Regel aus Metall ist.FIG. 1 shows the container 1, which, not shown in FIG. 1, is elastically connected to a motor, which has an eccentric mass at each end for generating the vibration, via a flange. In this embodiment, the container 1 is designed in a circular manner in a known manner and has an outer wall 2 and a core 3. In the case of vibrations of suitable frequency and amplitude, the bulk material moves in a spiral path in this container, as indicated by the arrows. The container can be closed with a lid 4 with a central lock 5 and handles 6. In the middle part of the central closure there is a water connection piece 7 with the water inlet 8 inside the container. The water serves to clean the bulk material and reaches the container again via the outlet 9 at the upper edge of the container, as indicated by the arrows W drawn out. The container is made in a known manner from a suitable plastic material, while the lid is usually made of metal.

Bei herkömmlichen Behältern kommt es oft im Bereich des Ueberganges zwischen der Kernwand und der unteren Wand zu Stauungen, die zu Beschädigungen kleiner und empfindlicher Stückgüter führen können. Es hat sich nun überraschenderweise gezeigt, dass durch die Einführung eines Kernmantels 10, der lose über den Kern 3 gestülpt wird, erhebliche Vorteile erzielt werden können, falls dieser Kernmantel die nachstehend beschriebenen Merkmale aufweist. So besitzt der Kernmantel gemäss Figur 1 Mittel zum Verzögern, respektive Abbremsen des Schüttgutes, wobei die Mittel im vorliegenden Fall Rippen 11 sind, die in Umfangrichtung angeordnet sind. Durch die Verwendung eines lose aufliegenden Mantels und der Rippen 11 konnte festgestellt werden, dass sowohl die Verletzungen des Stückgutes stark abnahmen als auch der Wirkungsgrad des Arbeitsprozesses zunahm. Dies wird durch die Erhöhung der Relativbewegung zwischen der vibrierenden Behälterwand und dem stark gedampft schwingenden Kermantel erklärt, wodurch das zu bearbeitende Stückgut gegenüber dem Trägermaterial stark abgebremst wird und somit auch eine höhere Relativbewegung und auch Abbremsung erhält. Wie aus dem Schnitt von Figur 1 hervorgeht, liegt der Kernmantel auf dem Kern 3 über dem Nocken 12a auf, und zentriert sich durch die Flügel 12, so dass ein Hohlraum 13 entsteht, durch den das Spülwasser W strömen kann, wodurch eine wesentlich wirkungsvollere und sparsamere Spülung erfolgt. Der Behälter 1 besitzt ferner eine Ablassvorrichtung mit Ablauf und Verschluss, die jedoch nicht eingezeichnet ist. Dabei kann diese Ablassvorrichtung unten oder im oberen Teil des Behälters angeordnet sein. Es kann sich auch als notwendig erweisen, oben am Kernmantel Oeffnungen 39 anzubringen, um den beim Vibrieren entstehenden Schaum abzulassen.With conventional containers, there is often congestion in the area of the transition between the core wall and the lower wall, which can lead to damage to small and sensitive piece goods. Surprisingly, it has now been shown that the introduction of a core jacket 10, which is placed loosely over the core 3, can achieve considerable advantages if this core jacket has the features described below. 1 has means for decelerating or braking the bulk material, the means in the present case being ribs 11 which are arranged in the circumferential direction. Through the use of a loose jacket and the ribs 11, it was found that both the injuries to the piece goods decreased sharply and the efficiency of the work process increased. This is explained by the increase in the relative movement between the vibrating container wall and the strongly steamed Kermantel, as a result of which the piece goods to be processed are braked sharply compared to the carrier material and thus also receive a higher relative movement and braking. As can be seen from the section in FIG. 1, the core jacket lies on the core 3 above the cam 12a and is centered by the vanes 12, so that a cavity 13 is created through which the rinsing water W can flow, which results in a much more effective and more economical flushing takes place. The container 1 also has a drain device with drain and closure, which is not shown. This discharge device can be arranged at the bottom or in the upper part of the container. It may also prove necessary to make openings 39 at the top of the core jacket in order to drain off the foam which is produced when vibrating.

In den Figuren 2 bis 5 sind verschiedene Ausführungsvarianten des Kernmantels 10 dargestellt, wobei der Kernmantel beispielsweise nur eine gewisse Anzahl radiale Rippen 14 im oberen Bereich des Kernmantels oder gemäss Figur 3 radiale, flügelförmige Rippen 15 am unteren Bereich des Kernmantels oder gemäss Figur 4 eine Anzahl radiale, flügelförmige Rippen 16 am oberen Teil des Kernmantels aufweisen kann oder diese flügelförmigen Rippen 16 mit treppenförmigen Stufen 17 am unteren Bereich des Kernmantels oder mit anderen Rippen, beispielsweise mit in Umfangsrichtung angeordneten Rippen 11 kombiniert sein kann.FIGS. 2 to 5 show different design variants of the core casing 10, the core casing, for example, only a certain number of radial ribs 14 in the upper region of the core casing or, according to FIG. 3, radial, wing-shaped ribs 15 at the lower region of the core casing or according to FIG can have radial, wing-shaped ribs 16 on the upper part of the core shell or these wing-shaped ribs 16 can be combined with step-shaped steps 17 on the lower region of the core shell or with other ribs, for example with ribs 11 arranged in the circumferential direction.

Während das Uebergangsstück 18 mit dem Einlass 8 des Zentralverschlusses in den Ausführungen gemäss Figuren 1 bis 3 sowie gemäss Figur 7 zylindrisch ist, kann das Uebergangsstück 19 auch quadratisch oder rechteckig sein, wobei die Oeffnung des Kernmantels entsprechend geformt ist. In Figur 6 ist überdies eine andere Art von radialen Rippen 20 dargestellt.While the transition piece 18 with the inlet 8 of the central closure is cylindrical in the designs according to FIGS. 1 to 3 and according to FIG. 7, the transition piece 19 can also be square or rectangular, the opening of the core jacket being shaped accordingly. Another type of radial ribs 20 is also shown in FIG.

In Figur 7 ist dargestellt, dass der Mittelpunkt B der Oeffnung 21 des Kernmantels 10 exzentrisch zum Mittelpunkt A des Behälters und des zylindrischen Uebergangsstücks 18 angeordnet ist, wodurch der Behälter in ungleiche Teile geteilt wird und eine bessere Durchmischung des Schüttgutes erfolgt.FIG. 7 shows that the center B of the opening 21 of the core casing 10 is arranged eccentrically to the center A of the container and the cylindrical transition piece 18, where is divided into unequal parts by the container and the bulk material is mixed better.

In den Figuren 2 bis 5 ist auch angedeutet, dass der Deckel 22 anstatt über einen Zentralverschluss an seinem Aussendurchmesser über ein Gewinde 23 in die Aussenwand 2 des Behälters eingeschraubt werden kann, wobei die Wasserzuführung ähnlich wie in anderen Ausführungen angeordnet ist.In FIGS. 2 to 5 it is also indicated that the lid 22 can be screwed into the outer wall 2 of the container instead of via a central lock on its outer diameter by means of a thread 23, the water supply being arranged similarly to other designs.

Es ist bei den Ausführungsvarianten gemäss den Figuren 4 und 5 auch möglich, anstatt der flügelähnlichen Rippen 16 dem Kernmantel eine kontinuierliche konkave Form 16K zu geben. Die Wirkung dieser konkaven Form kann zusätzlich dadurch verstärkt werden, dass der Deckel 24 einen umlaufenden Wulst 25 mit einer gegen die Aussenwand des Behälters verlaufenden Abrundung 26 erhält, sodass das Schüttgut besser an die konkave Form des Kernmantels geleitet wird. Dabei wird das Schüttgut durch den Radius R der Rundung 26 in die konkave Form K des Kernmantels geleitet und einerseits durch Druckerhöhung und andererseits durch Bremsung intensiver-bearbeitet.4 and 5, it is also possible to give the core jacket a continuous concave shape 16K instead of the wing-like ribs 16. The effect of this concave shape can be further enhanced by the fact that the cover 24 is provided with a circumferential bead 25 with a rounding 26 running against the outer wall of the container, so that the bulk material is better guided to the concave shape of the core shell. The bulk material is guided through the radius R of the rounding 26 into the concave shape K of the core jacket and is processed more intensively on the one hand by increasing the pressure and on the other hand by braking.

In Figur 8 ist ein Ausführungsbeispiel dargestellt, bei welchem durch die Verwendung des Kernmantels ein Behälter ohne Kern verwendet werden kann. Der Behälter 27 ist wie in den vorhergehenden Beispielen auf einem Antrieb 28 federnd gelagert und weist einen geschlossenen Abschlussdeckel 29 auf, der an seinem Umfang über ein Gewinde 30 mit der Behälterwand verschraubt werden kann. Wie eingangs erwähnt, ist es durch die Verwendung eines Kernmantels 31 möglich, einen Behälter ohne Kern zu verwenden, wodurch dessen Herstellung wesentlich vereinfacht und verbilligt wird. Der Kernmantel 31 kann sämtliche vorgehend beschriebenen Rippen und dergleichen aufweisen, die der Einfachheit halber hier nicht eingezeichnet sind. Der Kernmantel 31 wird unabhängig vom Behälter durch eine Halterung 32 gehalten, deren Ständer 33 fest mit dem Maschinensockel 34 verbunden ist. Am Ständer 33 ist ein Halterarm 35 verschiebbar befestigt, der den Kernmantel 31 trägt und festhält. Dadurch, dass der Halterarm verschiebbar am Ständer angeordnet ist, kann der Kernmantel entweder in der Mittelachse des Behälters oder verschoben gehalten werden, um den Behälter in zwei Teile unterschiedlicher Grösse zu unterteilen. Die Durchführung 36 in der Behälterwand für den Arm 35 ist derart bemessen, dass die Vibrationen vom Behälter nicht auf den Arm übertragen werden. Dadurch werden die verschiedenen Frequenzen und Amplituden in horizontaler und vertikaler Richtung nicht auf den Kernmantel übertragen, so dass daran eine optimale Bremsung des Schüttgutes erfolgt und dadurch eine bestmögliche Relativbewegung zwischen den zu bearbeitenden Stückgütern und dem Trägermaterial. Vorzugsweise ist der Arm 35 hohl ausgeführt und enthält eine Spülwasserzuleitung 37, die an den Kernmantel angeschlossen werden kann und von dort zu einem im Innern des Kernmantels angeordneten Wasseraustritt 38 führt, von wo das Wasser unter den Kernmantel hindurchgeführt wird, der nicht in seinem ganzen Umfang auf dem Behälterboden aufliegt. Es ist auch möglich, über eine parallele Zuleitung eine automatische Beschikkung von Zusatmitteln für die Bearbeitung als auch eine Druckluftleitung für die periodische Durchwirbelung des Schüttgutes anzuordnen.FIG. 8 shows an exemplary embodiment in which a container without a core can be used by using the core jacket. As in the previous examples, the container 27 is resiliently mounted on a drive 28 and has a closed end cover 29 which can be screwed to the container wall at its periphery by means of a thread 30. As mentioned at the beginning, the use of a core jacket 31 makes it possible to use a container without a core, as a result of which its manufacture is considerably simplified and less expensive. The core jacket 31 can have all the ribs and the like described above, which are not shown here for the sake of simplicity. The core jacket 31 is held independently of the container by a holder 32, the stand 33 is fixedly connected to the machine base 34. On the stand 33, a holder arm 35 is slidably mounted, which supports and holds the core jacket 31. Due to the fact that the holder arm is slidably arranged on the stand, the core jacket can either be held in the central axis of the container or can be displaced in order to divide the container into two parts of different sizes. The passage 36 in the container wall for the arm 35 is dimensioned such that the vibrations from the container are not transmitted to the arm. As a result, the various frequencies and amplitudes in the horizontal and vertical directions are not transferred to the core jacket, so that the bulk material is braked optimally and thus the best possible relative movement between the piece goods to be processed and the carrier material. The arm 35 is preferably hollow and contains a rinse water supply line 37 which can be connected to the core jacket and from there leads to a water outlet 38 arranged in the interior of the core jacket, from where the water is led under the core jacket, which is not all of its circumference rests on the bottom of the container. It is also possible to arrange an automatic loading of additives for processing as well as a compressed air line for the periodic swirling of the bulk material via a parallel feed line.

In einer weiteren Ausführungsvariante dazu ist es möglich, dem Kernmantel eine Bewegung zu erteilen, die. gegensinnig zur Bewegung der Behälterwand abläuft. Diese Bewegung des Kernmantels kann durch einen am Kernmantelkopf angeordneten Antrieb oder über eine Zuführung und Antriebsübertragung über den Arm 35 erfolgen.In a further embodiment variant, it is possible to give the core jacket a movement that. runs counter to the movement of the container wall. This movement of the core jacket can be carried out by a drive arranged on the core jacket head or via a feed and drive transmission via the arm 35.

Der Kernmantel wird vorzugsweise aus einem relativ abreibarmen Kunststoff hergestellt, doch kann es für besondere Fälle zweckmässig sein, ein anderes Material, beispielsweise Metall, dafür zu verwenden.The core jacket is preferably made of a relatively low-abrasion plastic, but it may be appropriate for special cases to use a different material, for example metal.

Der Kernmantel muss nicht notwendigerweise zylindrisch sein und kann beispielsweise eine ovale oder eckige Form aufweisen. Dergleichen kann der Behälter und gegebenenfalls dessen Kern, eine drei- oder mehreckige oder ovale Form aufweisen.The core jacket does not necessarily have to be cylindrical and can, for example, have an oval or angular shape. Likewise, the container and optionally its core can have a triangular or polygonal or oval shape.
