Definitions
- the present invention relates to a deburring, satinizing and polishing machine with a conveyor belt drive according to the preamble of claims 1, 6 and 9.
- the polishing medium is circulated by means of an endless conveyor belt in a trough-shaped polishing trough.
- This conveyor belt slides on the round wall of the polishing trough, which in turn is located in a tightly closed water container that also serves as a machine frame.
- the conveyor rollers necessary for the conveyor belt are stored outside on the water tank.
- this construction has the disadvantage that the polishing material has to be laboriously collected by hand after the polishing process, which is very time-consuming, especially for small parts such as cutlery or jewelry. Also, when changing the polishing medium, the polishing media must be removed manually from above with small buckets. On the other hand, the previous construction does not offer the user access behind and under the polishing trough for the periodic cleaning of the water container, where soap residues and other soiling are inevitable. In addition, the conveyor belt can only be changed by disassembling the polishing trough and the conveyor rollers. Another major disadvantage of this construction is the relatively high demand for soapy water and its disposal.
- the aim of the present invention is to further develop the known polishing machines with a conveyor belt drive in such a way that they become much more user-friendly and also more maintenance-friendly.
- the advantage of the polishing machine according to the invention is that by using a basket or cage after the polishing process has ended, the polishing material can be separated from the polishing medium in a simple and rapid manner.
- polishing medium remaining in the polishing trough can be removed quickly and easily from the polishing trough and even sorting out the polishing medium according to the size of the polishing bodies is possible.
- Another advantage is that quick access to the inside of the machine and economical use of polishing solution is achieved.
- a special container element in the form of a basket 28 is provided for the rapid removal of the polishing material, which is integrated into the polishing trough 2 during or after the polishing process has ended.
- the semicircular basket 28 with opening and two handles 26 in its semicircular wall 24 is matched as closely as possible to the diameter of the trough-shaped polishing trough and consists of a wire mesh or mesh.
- the basket is placed with its opening facing down into the polishing trough 2 on the polishing medium 21.
- the basket 28 is also driven by the rotation of the conveyor belt 9 and the polishing medium 21, so that the polishing medium including the material to be polished (or repeatedly) fall into the basket.
- the machine After the polishing process, the machine is stopped exactly at the point in time when the handles 26 of the basket 28 point upwards.
- the polishing bodies fall through the mesh of the grid, while the polishing material remains in the basket.
- the mesh size of the wire mesh is adapted to the size of the polishing material in order to keep the resistance when lifting as low as possible.
- a perforated plate with the largest possible opening can also be used.
- the end faces 25 of the basket 28 do not require passage openings for this function. However, in order to keep the weight of the basket as low as possible, it is more advantageous to also provide the end faces 25 as a wire mesh.
- the handles 26 can also be attached to the semicircular wall 24. To reduce the effort required when lifting, several of these baskets can be used side by side instead of one. This will be the case in particular if, instead of the polishing material, heavy polishing medium 21 such as steel itself has to be removed. For this purpose, one chooses passage openings that are smaller than the polishing body 21, or dispenses with any passage opening at all.
- FIG. 4 Another variant for the rapid separation of the polishing material from the medium 21 is a semicircular cage 29 (FIG. 4) which is closed on all sides, the semicircular wall 24 of which is matched as closely as possible to the diameter of the polishing trough 2 and the flat wall 27 of which is made of a wire mesh, mesh or a perforated plate with the largest possible passage.
- the semicircular wall 24 is rubberized to give as much hold on the conveyor belt 9.
- the cage 29 with the flat wall 27 is placed on the polishing medium 21.
- the cage 29 is also driven by the rotation of the conveyor belt 9 and the medium 21.
- the polishing material is pushed in front of the cage, while the polishing bodies 21 fall through the mesh of the flat wall 27 into the cage.
- the polishing material lies above the polishing medium and can be collected easily.
- the end faces 25 and the semicircular wall 24 do not require any through openings, but are also advantageously made of wire mesh in order to keep the weight as low as possible.
- both the basket 28 with opening and the cage 29 which is closed on all sides not only enable the polishing material to be separated, but also to sort out large and small polishing particles if the mixture of the polishing medium is to be changed.
- a new design is planned for more economical use of polishing solution and for quick access to the inside of the machine.
- the machine now only consists of a tubular frame 1 as a chassis, in which the trough-shaped polishing trough 2 is located. This is only screwed to the base frame on a single face. All conveyor rollers 6, 22 rotating on the running side of the conveyor belt are mounted directly on the polishing trough 2. For this purpose, the end faces of the polishing trough have a carrier profile 3 on the left and right.
- the conveyor belt 9 itself is only under full tension within the polishing trough 2 between the two upper conveyor rollers 6, 22 due to the weight of the polishing medium 21, while it is no longer under tension under the polishing trough.
- the former tensioning roller now only takes on the leveling function 22, 23 for centering the belt, and instead of rotating rollers, the rib reinforcements 20 below the polishing trough also serve as sliding surfaces for deflecting the conveyor belt 9. Since this is not under tension in its entire circumference the direction of rotation is given in a single direction.
- the endless belt is rotated via the drive roller 6 and pulls the polishing medium with it as tension. So that the conveyor belt 9 is held in its position and is protected against the penetration of polishing bodies between its running side and the sliding surface of the polishing trough, an insertion wall 4 with a flat profile by means of at least one cam 5b and a wing screw are on both end faces of the polishing trough 5a attached.
- a collecting tray 13 is attached to the base frame 1 below the polishing trough for falling grinding dust (in the dry process) or dripping polishing solution (in the wet process). This is advantageously presented in the form of a pull-out drawer so that cleaning is possible at any time.
- a small circulation pump is also provided in the engine compartment, which continuously conveys the dripping polishing solution from the drip tray back into the polishing trough.
- a valve 12 is available directly on the polishing trough for changing the lye, so that the lye can be drained both into the collecting pan underneath for disposal or directly into the sewage system. Since only the polishing trough is filled with polishing liquor, the need for water and polishing soap is reduced to a sixth compared to conventional construction.

Abstract
Description
Gegenstand der vorliegenden Erfindung ist eine Entgratungs, Satinier- und Poliermaschine mit Förderband-Antrieb nach dem Oberbegriff der Patentansprüche 1, 6, und 9.The present invention relates to a deburring, satinizing and polishing machine with a conveyor belt drive according to the preamble of
Bei 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 known polishing devices with a conveyor belt drive, the polishing medium is circulated by means of an endless conveyor belt in a trough-shaped polishing trough. This conveyor belt slides on the round wall of the polishing trough, which in turn is located in a tightly closed water container that also serves as a machine frame. The conveyor rollers necessary for the conveyor belt are stored outside on the water tank.
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. Einen ebenso großen Nachteil dieser Konstruktion ist der relativ große Bedarf an Seifenlaugen und deren Entsorgung.On the one hand, this construction has the disadvantage that the polishing material has to be laboriously collected by hand after the polishing process, which is very time-consuming, especially for small parts such as cutlery or jewelry. Also, when changing the polishing medium, the polishing media must be removed manually from above with small buckets. On the other hand, the previous construction does not offer the user access behind and under the polishing trough for the periodic cleaning of the water container, where soap residues and other soiling are inevitable. In addition, the conveyor belt can only be changed by disassembling the polishing trough and the conveyor rollers. Another major disadvantage of this construction is the relatively high demand for soapy water and its disposal.
Die vorliegende Erfindung hat zum Ziel, die bekannten Poliermaschinen mit Förderband-Antrieb so weiterzuentwickeln, daß diese wesentlich bedienerfreundlicher und auch unterhaltsfreundlicher werden.The aim of the present invention is to further develop the known polishing machines with a conveyor belt drive in such a way that they become much more user-friendly and also more maintenance-friendly.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale der Patentansprüche 1, 6, und 9This object is achieved by the characterizing features of
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.The advantage of the polishing machine according to the invention is that by using a basket or cage after the polishing process has ended, the polishing material can be separated from the polishing medium in a simple and rapid manner.
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.Furthermore, there is the advantage that the polishing medium remaining in the polishing trough can be removed quickly and easily from the polishing trough and even sorting out the polishing medium according to the size of the polishing bodies is possible.
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.
Im folgenden wird die Erfindung anhand von mehrere Ausführungswege darstellenden Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In the following, the invention will be explained in more detail with reference to drawings showing several possible embodiments.

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.A special container element (FIG. 3) in the form of a
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.Instead of a wire mesh, a perforated plate with the largest possible opening can also be used. The end faces 25 of the
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 from the
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
Für sparsameren Polierlaugenverbrauch sowie für rasche Zugänglichkeit des Maschineninneren ist eine neue Bauart vorgesehen.A new design is planned for more economical use of polishing solution and for quick access to the inside of the machine.
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 now only consists of a
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.A collecting
