Abstract
Description
Die vorliegende Erfindung betrifft einen Scheuerbehälter zum Finishen, z.B. Entgraten, Polieren u. dgl. von Gegenständen, z.B. Gummi- oder Kunststoffteilen durch bei Bewegung des Scheuerbehälters erfolgende Reibung zwischen den zu bearbeitenden Gegenständen und mit diesen vermischten Schleifkörpern, sowie eine Anordnung derartiger Scheuerbehälter.The present invention relates to a scouring container for finishing, eg deburring, polishing and. the like. articles, eg rubber or plastic parts of such through takes place during movement of the scouring container friction between the objects to be processed and with these mixed abrasives, as well as an array S c year container.
Zum Entgraten und Polieren von Gegenständen aus verschiedenen Materialien, insbesondere Kunststoffe ist es bekannt, Scheuerbehälter zu verwenden, in die die Gegenstände, vermischt mit Schleifkörpern verschiedenen Formates gefullt werden. Bei Bewegung des Scheuerbehälters, z.B. Rotation oder Vibration, wird durch die Reibung der Schleifkörper die Entgratung bzw. der Poliervorgang bewirkt. Derartige Scheuerbehälter müssen insbesondere bezüglich ihrer Abriebfestigkeit ausgelegt sein und es ist daher bekannt, Metallbehälter mit Gummi- oder Kunststoffauflagen zu versehen. Aufgrund seiner besonders guten Abriebfestigkeit wird häufig auch Polyurethanelastomer verwendet. Ein bisher ungelöstes Problem bei diesen Scheuerbehältern besteht allerdings in der sehr großen Lärmentwicklung im Betrieb. Diese liegt beispielsweise bei etwa 120 dB und bedeutet somit eine erhebliche Umweltbelastung des Arbeitsplatzes. Diese Belastung ist umso größer, als beispielsweise in der Schmuckindustrie, für die Herstellung von Modeschmuck derartige Scheuerbehälter in großer Anzahl in riesigen Sälen arbeiten, sodaß eine gewisse Kommulation in der Lärmbelastung auftritt.For deburring and polishing objects made of different materials, in particular plastics, it is known to use scrubbing containers into which the objects, mixed with grinding wheels of different formats, are filled. When moving the scrubbing container, e.g. Rotation or vibration, deburring or polishing is caused by the friction of the grinding wheels. Such scrubbing containers must be designed in particular with regard to their abrasion resistance and it is therefore known to provide metal containers with rubber or plastic pads. Due to its particularly good abrasion resistance, polyurethane elastomer is often used. A problem that has not yet been solved with these scrubbing containers, however, is the very large amount of noise generated in the company. This is around 120 dB, for example, and therefore means a significant environmental impact on the workplace. This burden is all the greater, for example in the jewelry industry, for the manufacture of fashion jewelry, such scrubbing containers work in large numbers in huge halls, so that a certain commutation occurs in the noise pollution.
Die vorliegende Erfindung hat sich daher die Schaffung eines Scheuerbehälters zum Ziel gesetzt, der nicht nur bezüglich seiner Abriebsfestigkeit eine sehr große Lebensdauer aufweist, sondern der darUber hinaus auch eine starke Reduktion des Schallpegels im Betrieb ermöglicht.The present invention has therefore set itself the goal of creating a scrubbing container which not only has a very long service life with regard to its abrasion resistance, but which also enables a strong reduction of the sound level during operation.
Dies wird erfindungsgemäß dadurch erreicht, daß der Scheuerbehälter Wände aus mit einem Versteifungsskelett versehenen Polyurethanelastomer besitzt.This is achieved according to the invention in that the scrubbing container has walls made of a polyurethane elastomer provided with a stiffening skeleton.
Durch diese Ausbildung ist erreicht, daß die Wände des Scheuerbehälters durch die elastische Deformationsmöglichkeit beim Aufprallen des Füllgutes von vornherein einen beachtlichen Teil an Schallenergie einerseits gar nicht entstehen lassen und andererseits erheblich dämpfen.This design ensures that the walls of the scrubbing container, on the one hand, do not allow a considerable part of the sound energy to arise and, on the other hand, dampen them considerably due to the possibility of elastic deformation when the filling material impacts.
Die Nachgiebigkeit des erfindungsgemäßen Scheuerbehälters, die für seinen Einbau als Maschinenteil nachteilig wäre, wird, was seine Außenmaße betrifft, dadurch behoben, daß ein Versteifungsskelett vorgesehen ist. Dieses Versteifungsskelett definiert und fixiert den Behälter bezüglich seiner Größe und geometrischen Ausgestaltung, während die Wände, die zwischen dem Versteifungsskelett angeordnet sind, elastisch nachgiebig bleiben.The resilience of the scrubbing container according to the invention, which would be disadvantageous for its installation as a machine part, is eliminated, as far as its external dimensions are concerned, by providing a stiffening skeleton. This stiffening skeleton defines and fixes the container in terms of its size and geometric configuration, while the walls which are arranged between the stiffening skeleton remain resiliently flexible.
Eine Ausgestaltung der Erfindung sieht vor, daß der Scheuerbehälter als einseitig offenes, mit einem Stirnteil schließbares Prisma ausgebildet ist, dessen zwischen den Seitenwänden liegende Kanten mit Stäben, z.B. aus Metall, als Versteifungsskelett versehen sind. Die an sich für derartige Scheuerbehälter bekannte AusfUhrung als Prisma ermöglicht eine trommelförmige Rotation, wobei das FUllgut immer wieder an die Wännde anprallt und somit die gewünschte Reibung zwischen dem zu bearbeitenden Gut und den Schleifkörpern eintritt. Daß das Prisma auf einer Seite durch einen Stirnteil verschließbar ist, hat den Vorteil der guten Reinigungsmöglichkeit. Darüber hinaus ist dies auch für die Herstellung eine vorteilhafte Ausgestaltung, da dann ein druckloser Gießvorgang in einer offenen Form angewendet werden kann. Dadurch sind nur geringe Formkosten notwendig und die Herstellung kann äußerst rationell erfolgen.An embodiment of the invention provides that the scrubbing container is designed as a prism which is open on one side and can be closed with a front part, the edges of which lie between the side walls and are provided with rods, for example made of metal, as a stiffening skeleton. The design as a prism, known per se for such scrubbing containers, enables drum-shaped rotation, the filling material repeatedly hitting the walls and thus the desired friction between the material to be processed and enters the grinding wheels. The fact that the prism can be closed on one side by a front part has the advantage of being easy to clean. In addition, this is also an advantageous embodiment for the production, since then an unpressurized casting process can be used in an open mold. As a result, only low molding costs are necessary and the production can be carried out extremely efficiently.
Die Anordnung der Stäbe in den zwischen den Seitenwänden liegenden Kanten fuhrt genau zum gewünschten Effekt, nämlich der elastischen Durchschwingmöglichkeit der Seitenwände. Gerade dadurch wird die Lärmentwicklung stark herabgesetzt.The arrangement of the bars in the edges lying between the side walls leads exactly to the desired effect, namely the elastic swing-through possibility of the side walls. This is precisely the reason why noise is greatly reduced.
Eine vorteilhafte Ausgestaltung sieht vor, daß die Stäbe durch in Polyurethanelastomer eingegossene Rohre gesteckt sind. Dadurch wird einerseits eine zusätzliche Versteifung der Kanten erzielt und andererseits definieren diese Rohre dann die Kantenlänge, wärend die durch das Rohr gesteckten Stäbe zur Fixierung des Stirnteiles bzw. zum Zusammenbau des Scheuerbehälters Uberhaupt in einfacher Weise zur Verfügung stehen. Es ist dadurch auch gewährleistet, daß auf die Stäbe wirkende Kräfte sich nicht nachteilig auf die Stabilität des Behälters auswirken, was der Fall sein könnte, wenn die Stäbe direkt in die Wand eingegossen sind und somit die Verbindung zwischen den Stäben und dem Polyurethanelastomer direkt bestünde.An advantageous embodiment provides that the rods are inserted through pipes cast in polyurethane elastomer. On the one hand, this results in additional stiffening of the edges and, on the other hand, these tubes then define the edge length, while the rods inserted through the tube are generally available in a simple manner for fixing the end part or for assembling the scrubbing container. This also ensures that forces acting on the rods do not adversely affect the stability of the container, which could be the case if the rods are cast directly into the wall and thus the connection between the rods and the polyurethane elastomer would be direct.
Um für einen guten Sitz der Rohre in den Behälterwänden zu Sorgen, ohne daß diese deshalb insgesamt dicker ausbebildet werden müssen, ist es zweckmäßig, wenn die zur Aufnahme der Stäbe dienenden Kanten verdickt ausgebildet sind. Dadurch ist eine erhöhte Festigkeit an dieser Stelle gegeben und es ist auch gesichert, daß die Dicke des Polyurethanelastomers an dieser Stelle nirgendwo zu gering wird.In order to ensure a good fit of the tubes in the container walls, without them having to be made thicker overall, it is expedient if the edges serving to receive the rods are thickened. This gives increased strength at this point and it is also ensured that the thickness of the polyurethane elastomer is nowhere too thin at this point.
Eine weitere zweckmäßige Ausgestaltung der Erfindung sieht vor, daß über Boden- und Stirnteil des Scheuerbehälters starre Scheiben angeordnet sind, durch die die Enden der Stäbe gesteckt und gegen die sie fixiert, z.B. verschraubt sind. Durch die Verwendung der starren Scheiben ist auch in der Ebene normal zu den Stäben eine Versteifung gegeben, wobei zugleich eine einfache Montagemöglichkeit vorliegt. Für den Zusammenbau des Behälters ist es nur erforderlich, die Scheiben, die an den Durchdringungspunkten der Stäbe entsprechende Löcher aufweisen, über die Stäbe zu stecken und durch Verschraubung zu fixieren. Die Scheiben.können ebenso wie die Stäbe aus Metall, beispielsweise Eisen bestehen. Zweckmäßig ist es, wenn die Scheiben den Boden und/oder Stirnteil überragen und kreisrund ausgebildet sind.A further expedient embodiment of the invention provides that rigid disks are arranged above the bottom and front part of the scrubbing container, through which the ends of the rods are inserted and against which they are fixed, e.g. are screwed. By using the rigid washers, there is also a stiffening in the plane normal to the bars, and at the same time there is an easy mounting option. To assemble the container, it is only necessary to put the disks, which have corresponding holes at the penetration points of the rods, over the rods and to fix them by means of screwing. Like the rods, the disks can be made of metal, for example iron. It is expedient if the disks protrude beyond the base and / or front part and are circular.
Durch das Überragen ist eine gewisse Schutzfunktion gegen Arbeitsunfälle gegeben, da die Kanten und Ecken des Scheuerbehälters, die bei Rotation eine Verletzungsgefahr darstellen, abgedeckt sind. Durch das Überragen der kreisrunden Scheiben ist weiters die Möglichkeit gegeben, den Scheuerbehälter indirekt durch Anpressen dieser Scheiben an ein rotierendes Rad zu bewerkstelligen. Ebenso ist jedoch ein Direktantrieb über einen an den Scheiben mittig befestigten Zapfen möglich.The protrusion provides a certain protective function against accidents at work, since the edges and corners of the scrubbing container, which pose a risk of injury when rotating, are covered. By protruding from the circular disks, there is also the possibility of indirectly accomplishing the scrubbing container by pressing these disks against a rotating wheel. However, a direct drive is also possible via a pin attached to the center of the disks.
Im Rahmen der vorliegenden Erfindung ist auch eine Anordnung von Scheuerbehältern vorteilhaft, wonach zwei oder mehrere Scheuerbehälter hintereinander angeordnet und mittels die Behälter gemeinsam durchsetzender, gegen endseitig angeordnete Scheiben fixierter stäbe, verbunden sind.Within the scope of the present invention, an arrangement of scrubbing containers is also advantageous, according to which two or more scrubbing containers are arranged one behind the other and by means of those which pass through the containers and are arranged towards the ends Disks of fixed rods, are connected.
Bei dieser Anordnung ist die vorstehend ausgeführte Montagemöglichkeit der Scheiben mit den Stäben besonders zweckmäßig da einfach mehrere Behälter hintereinander durch gemeinsame Stäbe verbunden werden können, wobei die Stäbe zum Zusammenspannen der als Endfixierung dienenden Scheiben verwendet werden können.In this arrangement, the above-described possibility of mounting the disks with the rods is particularly expedient since simply several containers can be connected one behind the other by means of common rods, the rods being able to be used to clamp together the disks serving as end fixings.
Im einfachsten Falle sind zwei Behälter auf diese Weise verbunden, wobei diese beiden Behälter mit ihren Böden gegeneinander liegen, während die Öffnungen der Scheuerbehalter auf beiden Seiten mit Stirnteilen abgedeckt sind. Das Zusammenspannen der beiden Behälter erfolgt dann durch über den beiden Stirnteilen befindliche.Scheiben, wobei die Stirnteile und die Scheiben zweckmäßig auch einstückig ausgebildet sein können, das heißt, daß der Stirnteil, der ebenfalls aus Polyurethanelastomer besteht, auf die Scheibe-direkt aufgegossen ist.In the simplest case, two containers are connected in this way, these two containers lying with their bottoms against one another, while the openings of the scrubbing containers are covered on both sides with end pieces. The two containers are then clamped together by means of washers located above the two end parts, the end parts and the washers also advantageously being able to be formed in one piece, that is to say that the end part, which likewise consists of polyurethane elastomer, is poured directly onto the washer.
Im folgenden wird die Erfindung anhand der Zeichnungen beispielhaft näher erläutert.The invention is explained in more detail below by way of example with reference to the drawings.
