Description

Gegenstand der vorliegenden Erfindung ist eine Entgratungs, Satinier- und Poliermaschine mit Förderband-Antrieb nach dem Oberbegriff der Patentansprüche 1 und 5.The present invention relates to a deburring, Satinizing and polishing machine with conveyor belt drive after the preamble of claims 1 and 5.

Eine solche Maschine ist aus der WO 93/07992 bekannt. Hier wird ein umlaufendes Förderband verwendet, das in einem Trog aufgenommen ist. Das Band paßt sich in seiner Formgebung an die eingelegten, zu polierenden Gegenstände an, wobei die das Band tragenden Rollen in der Polierflüssigkeit laufen.Such a machine is known from WO 93/07992. Here a revolving conveyor belt is used, which in a trough is included. The band fits in his Shaping the inlaid objects to be polished at, the roles supporting the tape in the Running polishing liquid.

Bei anderen bekannten Poliergeräten mit Förderband-Antrieb wird das Poliermedium mittels eines endlosen Förderbandes in einem muldenförmigen Poliertrog in Umwälzung versetzt. Dieses Förderband gleitet auf der runden Wandung des Poliertrogs, der sich wiederum in einem dicht verschlossenen, gleichzeitig als Maschinengestell dienenden Wasserbehälters befindet. Die für das Förderband notwendigen Förderrollen sind außerhalb an dem Wasserbehälter gelagert.In other known polishing devices with conveyor belt drive is the polishing medium by means of an endless conveyor belt circulated in a trough-shaped polishing trough. This conveyor belt slides on the round wall of the Polishing trough, which in turn is dense closed, which also serves as a machine frame Water tank. The one for the conveyor belt necessary conveyor rollers are outside on the Water tank stored.

Diese Konstruktion hat einerseits den Nachteil, daß das Poliergut nach dem Polierprozess mühsam von Hand eingesammelt werden muß, was vor allem bei Kleinteilen wie Essbestecken oder Schmuckteilen sehr zeitraubend ist. Auch müssen bei einem Wechsel des Poliermediums die Polierkörper manuell von oben mit kleinen Eimern entfernt werden. Anderseits bietet die bisherige Konstruktion dem Benützer keinen Zugang hinter und unter den Poliertrog für die periodische Reinigung des Wasserbehälters, wo sich zwangsläufig Seifenrückstände und andere Verschmutzungen bilden. Außerdem kann ein Förderband-Wechsel nur durch Demontage des Poliertrogs und der Förderrollen stattfinden. On the one hand, this construction has the disadvantage that Polished material after the polishing process laboriously by hand must be collected, especially with small parts such as Cutlery or jewelry is very time consuming. Also the polishing media must be changed when changing the polishing medium can be removed manually from above with small buckets. On the other hand, the previous construction offers the user no access behind and under the polishing trough for the periodic cleaning of the water tank wherever inevitably soap residues and other soiling form. In addition, a conveyor belt can only be changed Disassembly of the polishing trough and the conveyor rollers take place.

Einen ebenso großen Nachteil dieser Konstruktion ist der relativ große Bedarf an Seifenlaugen und deren Entsorgung.Another disadvantage of this construction is that relatively large demand for soapy water and its disposal.

Die US 4 034 520 offenbart eine Vorrichtung für die Endbearbeitung von Teilen mittels Vibration. Jedes Teil ist hierbei in einem Korb aufgenommen, der gegenüber der Vorrichtung nur in begrenztem Umfang beweglich ist. Das Aufnehmen mehrerer Teile in einem Korb sowie das Problem des entnehmens nach einer längeren Bearbeitung unter Verdrehung des Korbes sind nicht angesprochen.US 4 034 520 discloses an apparatus for the Finishing parts by vibration. Every part is included in a basket opposite the Device is only movable to a limited extent. The Picking up multiple parts in one basket as well as the problem after a long period of processing Twisting of the basket is not addressed.

Die vorliegende Erfindung hat zum Ziel, die bekannten Poliermaschinen mit Förderband-Antrieb so weiterzuentwickeln, daß diese wesentlich bedienerfreundlicher und auch unterhaltsfreundlicher werden.The present invention aims to the known To further develop polishing machines with conveyor belt drives that these are much more user-friendly and also become more maintenance-friendly.

Gelöst wird diese Aufgabe durch die Merkmale der Patentansprüche 1 und 5.This task is solved by the characteristics of Claims 1 and 5.

Vorteil des erfindungsgemäßen Poliermaschine ist, daß durch Einsatz eines Korbes oder Käfigs nach Beendigung des Polierprozesses das Poliergut in einfacher und rascher Weise vom Poliermedium getrennt werden kann.Advantage of the polishing machine according to the invention is that by Use of a basket or cage after completion of the The polishing process in easier and faster Can be separated from the polishing medium.

Weiterhin besteht der Vorteil, daß das im Poliertrog verbleibende Poliermedium rasch und einfach aus dem Poliertrog entnommen werden kann und sogar ein Aussortieren des Poliermediums nach Größe der Polierkörper möglich wird.Another advantage is that this is in the polishing trough remaining polishing medium quickly and easily from the Polishing trough can be removed and even sorted out of the polishing medium is possible according to the size of the polishing body.

Weiterer Vorteil ist, daß eine rasche Zugänglichkeit des Maschineninneren sowie ein sparsamer Polierlaugenverbrauch erreicht wird.Another advantage is that quick access to the Inside of the machine and economical use of polishing solution is achieved.

Zur raschen Entnahme des Polierguts ist ein spezielles Behälterelement (Fig. 3) in Form eines Korbes 28 vorgesehen, der während oder aber auch nach Beendigung des Polierprozesses in den Poliertrog 2 integriert wird. Der halbrunde Korb 28 mit Öffnung und zwei Handgriffen 26 ist in seiner halbrunden Wandung 24 dem Durchmesser des muldenförmigen Poliertrogs möglichst genau angepaßt und besteht aus einem Drahtgitter oder -geflecht. Der Korb wird mit seiner Öffnung nach unten in den Poliertrog 2 auf das Poliermedium 21 aufgesetzt. Durch die Drehung des Förderbandes 9 und des Poliermediums 21 wird der Korb 28 mitangetrieben, so daß das Poliermedium inkl. Poliergut (bzw. immer wieder) in den Korb fallen. Nach dem Polierprozess wird die Maschine genau zu dem Zeitpunkt gestoppt, wo die Handgriffe 26 des Korbes 28 nach oben zeigen. Beim Herausheben des gefüllten Korbes fallen die Polierkörper durch die Maschen des Gitters, während das Poliergut im Korb zurückbleibt. Die Maschenweite des Drahtgitters wird jeweils der Größe des Polierguts angepaßt, um den Widerstand beim Hochheben möglichst gering zu halten.There is a special one for quick removal of the polishing material Container element (FIG. 3) in the form of a basket 28 provided that during or after the end of Polishing process is integrated in the polishing trough 2. Of the semicircular basket 28 with opening and two handles 26 is in its semicircular wall 24 the diameter of the trough-shaped polishing trough adapted as precisely as possible and consists of a wire mesh or mesh. The basket will with its opening down into the polishing trough 2 on the Polishing medium 21 placed. By rotating the Conveyor belt 9 and the polishing medium 21 becomes the basket 28 co-driven, so that the polishing medium incl (or repeatedly) fall into the basket. After this The machine's polishing process is exactly at that point stopped where the handles 26 of the basket 28 go up demonstrate. When you lift the filled basket, they fall Polish through the mesh of the grid while the Polish remains in the basket. The mesh size of the Wire mesh is the size of the polishing material adapted to the resistance when lifting as low as possible to keep.

Anstelle eines Drahtgitters kann auch ein Lochblech mit größtmöglichem Durchlaß verwendet werden. Die Stirnseiten 25 des Korbes 28 benötigen für diese Funktion keine Durchlaßöffnungen. Um jedoch das Eigengewicht des Korbes so gering wie möglich zu halten, ist es vorteilhafter, die Stirnseiten 25 ebenfalls als Drahtgitter vorzusehen. Die Handgriffe 26 können auch an der halbrunden Wandung 24 angebracht sein. Um den Kraftaufwand beim Hochheben zu reduzieren, können anstelle eines einzigen auch mehrere dieser Körbe nebeneinander angewendet werden. Dies wird vor allem dann der Fall sein, wenn anstelle des Polierguts schweres Poliermedium 21 wie z.B. Stahl selbst entfernt werden muß. Dazu wählt man jeweils Durchlaßöffnungen, die kleiner als die Polierkörper 21 sind, oder verzichtet überhaupt auf jegliche Durchlaßöffnung.A perforated plate can also be used instead of a wire mesh maximum possible passage can be used. The end faces 25 of the basket 28 do not require any for this function Outlet openings. However, the weight of the basket to keep it as low as possible, it is more advantageous to End faces 25 also to be provided as a wire mesh. The Handles 26 can also be on the semicircular wall 24 to be appropriate. To the effort when lifting can reduce, instead of a single, several these baskets can be used side by side. This will be done before be the case if instead of the polishing material heavy polishing medium 21 such as Steel itself removed must become. To do this, select passage openings that are smaller than the polishing body 21, or dispensed with any passage opening at all.

Eine andere Variante zur raschen Trennung des Polierguts vom Medium 21 ist ein allseitig verschlossener, halbrunder Käfig 29 (Fig. 4), dessen halbrunde Wandung 24 dem Durchmesser des Poliertrogs 2 möglichst genau angepaßt ist und dessen flache Wandung 27 aus einem Drahtgitter, - geflecht oder einem Lochblech mit größtmöglichem Durchlaß besteht. Die halbrunde Wandung 24 ist gummiert, um möglichst viel Halt auf dem Förderband 9 zu geben. Während oder nach Beendigung des Polierprozesses wird der Käfig 29 mit der flachen Wandung 27 auf das Poliermedium 21 gesetzt. Durch die Drehung des Förderbandes 9 und des Mediums 21 wird auch der Käfig 29 angetrieben. Dabei wird das Poliergut jeweils vor den Käfig hergeschoben, während die Polierkörper 21 durch die Maschen der flachen Wandung 27 in den Käfig fallen. Wird die Maschine in dem Zeitpunkt gestoppt, wo die flache Wandung nach oben zeigt, liegt das Poliergut oberhalb des Poliermediums und kann auf leichte Weise eingesammelt werden. Die Stirnseiten 25 sowie die halbrunde Wandung 24 benötigen keine Durchlaßöffnungen, werden aber vorteilhafter ebenfalls aus Drahtgitter gefertigt, um das Eigengewicht möglichst gering zu halten.Another variant for the rapid separation of the polishing material of medium 21 is a semicircular, closed on all sides Cage 29 (Fig. 4), the semicircular wall 24 of the Diameter of the polishing trough 2 is adapted as precisely as possible and its flat wall 27 made of a wire mesh, braid or a perforated plate with the largest possible opening consists. The semicircular wall 24 is rubberized to to give as much hold on the conveyor belt 9. While or after the polishing process is completed, the cage 29 with the flat wall 27 placed on the polishing medium 21. By rotating the conveyor belt 9 and the medium 21st the cage 29 is also driven. It will Polished material pushed in front of the cage, while the Polishing body 21 through the mesh of the flat wall 27 in drop the cage. The machine at the time stopped where the flat wall is facing up, that's it Polished material above the polishing medium and can be light Way to be collected. The end faces 25 and the semicircular wall 24 do not need through openings, but are also more advantageous from wire mesh made to keep the weight as low as possible.

Beide Varianten, sowohl der Korb 28 mit Öffnung als auch der allseitig verschlossene Käfig 29, ermöglichen auf diese Weise nicht nur das Trennen von Poliergut, sondern auch das Aussortieren von großen und kleinen Polierkörpern, wenn die Mischung des Poliermediums verändert werden soll.Both variants, both the basket 28 with opening and the cage 29, which is closed on all sides, enables this Do not only separate the polishing material, but also that Sort out large and small polishing particles if the Mixture of the polishing medium should be changed.

Anstelle des "Zwei-Trog-Systems" besteht die Maschine neu nur noch aus einem Rohrgestellrahmen 1 als Chassis, worin sieh der muldenförmige Poliertrog 2 befindet. Dieser ist nur an einer einzigen Stirnseite am Grundgestell angeschraubt. Alle auf der Laufseite des Förderbands rotierenden Förderrollen 6, 22 sind direkt am Poliertrog 2 gelagert. Zu diesem Zweck weisen die Stirnseiten des Poliertrogs links und rechts ein Trägerprofil 3 auf. Das Förderband 9 selbst steht nur innerhalb des Poliertrogs 2 zwischen den beiden oberen Förderrollen 6, 22 durch das Gewicht des Poliermediums 21 unter voller Spannung, während es unterhalb des Poliertrogs nicht mehr unter Spannung steht. Die einstige Spannwalze übernimmt damit nur noch die Nivellierfunktion 22, 23 zum Zentrieren des Bandes, und anstelle von rotierenden Walzen dienen die Rippenverstärkungen 20 unterhalb des Poliertrogs gleichzeitig als Gleitflächen zur Umlenkung des Förderbandes 9. Da dieses nicht in seinem ganzen Umfang unter Spannung liegt, ist der Drehsinn in eine einzige Richtung vorgegeben. Das Endlosband wird über die Antriebswalze 6 gedreht und zieht das Poliermedium als Spannung dienend mit. Damit das Förderband 9 in seiner Position gehalten wird und gegen das Eindringen von Polierkörpern zwischen seine Laufseite und der Gleitfläche des Poliertrogs geschützt ist, sind an beiden Stirnseiten des Poliertroges eine Einsetzwand 4 mit einem Flachprofil mittels mindestens einer Nocke 5b und einer Flügelschraube 5a befestigt. Diese beiden Einsetzwände lassen sich bei einem Förderbandwechsel auf leichte Weise entfernen, so daß das Band lediglich hochzuhalten und seitlich über den Poliertrog zu streifen ist, ohne die Förderwalzen zu demontieren. Die Spannung des neuen Bandes ergibt sich von selbst, sobald das Poliermedium wieder eingefüllt wurde. Für rasche Zugänglichkeit ist vorgesehen, daß die gesamte horizontale Maschinenabdeckung 14, 15 inkl. mindestens eine Seitenverschalung 19b mittels einer Scharnierachse 16 aufklappbar ist.Instead of the "two-trough system", the machine is new only from a tubular frame 1 as a chassis, wherein see the trough-shaped polishing trough 2. This is only on a single face on the base frame screwed on. All on the running side of the conveyor belt rotating conveyor rollers 6, 22 are directly on the polishing trough 2 stored. For this purpose, the front faces of the Polishing trough on the left and right a support profile 3. The The conveyor belt 9 itself is only inside the polishing trough 2 between the two upper conveyor rollers 6, 22 by the Weight of the polishing medium 21 under full tension while it is no longer under tension below the polishing trough stands. The former tensioning roller now only takes over Leveling function 22, 23 for centering the belt, and instead of rotating rollers Rib reinforcements 20 below the polishing trough at the same time as sliding surfaces for deflecting the Conveyor belt 9. Since this is not in its entirety is under tension, the sense of rotation is in one Direction specified. The endless belt is about the Drive roller 6 rotated and pulls the polishing medium as Serving with excitement. So that the conveyor belt 9 in its Position is held and against the ingress of Polishing bodies between its running side and the sliding surface of the polishing trough are protected on both ends of the polishing trough an insert wall 4 with a flat profile by means of at least one cam 5b and a wing screw 5a attached. These two insert walls can be used for remove a conveyor belt change easily, so that just hold the tape up and over the side The polishing trough can be brushed without the conveyor rollers closing disassemble. The tension of the new volume results from even as soon as the polishing medium has been refilled. For quick access, it is envisaged that the entire horizontal machine cover 14, 15 including at least one Side formwork 19b by means of a hinge axis 16 can be opened.

Für herunterfallenden Schleifstaub (bei Trockenverfahren) oder herunter tropfende Polierlauge (bei Nassverfahren) ist unterhalb des Poliertroges eine Auffangwanne 13 am Grundgestell 1 befestigt. Diese wird vorteilhaft in Form einer ausziehbaren Schublade dargestellt, damit eine Reinigung jederzeit möglich ist. Für Polierzwecke im Nassverfahren wird zusätzlich im Motorraum eine kleine Umwälzpumpe vorgesehen, welche kontinuierlich die heruntertropfende Polierlauge von der Auffangwanne zurück in den Poliertrog befördert. Für den Laugenwechsel steht ein Ventil 12 direkt am Poliertrog zur Verfügung, so daß die Lauge sowohl in die darunterliegende Auffangwanne zur Entsorgung oder direkt in die Kanalisation abgelassen werden kann. Da nur noch der Poliertrog mit Polierlauge gefüllt wird, reduziert sich der Bedarf an Wasser und Polierseife auf ein Sechstel gegenüber herkömmlicher Bauart.For falling grinding dust (in dry processes) or dripping polishing solution (in wet processes) below the polishing trough a drip pan 13 on Base frame 1 attached. This is advantageous in shape a pull-out drawer shown, so a Cleaning is possible at any time. For polishing purposes in Wet process also becomes a small one in the engine compartment Circulation pump provided, which continuously the dripping polishing solution back from the drip pan transported to the polishing trough. For the change of lye stands a valve 12 is available directly on the polishing trough, so that the lye both in the collecting pan underneath Disposal or drained directly into the sewage system can be. Since only the polishing trough with polishing lye is filled, the need for water and Polishing soap to a sixth compared to conventional Design type.
