Vorrichtung zum Abtransport von Spänen und KühlflüssigkeitDevice for the removal of chips and coolant
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zum Abtransport der an einer Werkzeugmaschine anfallenden Späne und Kühlflüssigkeit, wobei nachfolgend unter „Kühlflüssigkeit" gegebenenfalls auch enthaltene Beimengungen anderer Flüssigkeiten, z.B. Öl, zu verstehen sind.The invention relates to a device for the removal of the chips and coolant accumulating on a machine tool, the term “coolant” also being used to include admixtures of other liquids, for example oil, if appropriate.
In mechanischen Werkstätten fallen bei den dort eingesetzten Werkzeugmaschinen Späne und Kühlflüssigkeit, die zum Teil auch von Öl durchsetzt sein können an und erfordern einen Abtransport zu ihrer Entsorgung. Zu diesem Zweck werden die angefallenen Stoffe zu Sammelstellen geführt, und dort werden sie in der Regel separiert. Die Späne können dann zumeist wieder eingeschmolzen werden. Für die Kühlflüssigkeit kommt nach einer Filtrierung ein Wiedereinsatz in Betracht. Dies gilt auch zum Teil für Ölrückstände. Etwa nicht verwertbare Stoffe müssen einer Sonderentsorgung zugeführt werden.In mechanical workshops, the machine tools used there produce chips and coolant, some of which may also have oil in them, and require removal for disposal. For this purpose, the substances are taken to collection points, where they are usually separated. The chips can then mostly be melted down again. Reuse is possible for the coolant after filtering. This also applies in part to oil residues. Substances that cannot be used must be disposed of separately.
Ein unkontrolliertes Austreten der Späne und der Kühlflüssigkeit mit etwaigen Ölrückständen muss dringend vermieden werden, um insbesondere Beschädigungen im Boden zu vermeiden.An uncontrolled escape of the chips and the coolant with any oil residues must be avoided urgently, in particular to avoid damage to the floor.
Demzufolge sind an Vorrichtungen zum Abtransport von Spänen und Kühlflüssigkeit hohe Sicherheitsanforderungen zu stellen, welche das Auslaufen der betroffenen Stoffe mit hoher Zuverlässigkeit vermeiden. Insbesondere müssen diese Vorrichtungen sicherstellen, dass bei Notabschaltungen des Abtransports der genannten Stoffe, z.B. aufgrund von Verstopfungen, in den Abführleitungen ein ausreichendes Speichervolumen so lange noch aufgenommen werden kann, bis ein kompletter Bearbeitungszyklus der jeweiligen Maschine abgeschlossen werden kann. Eine Unterbrechung eines solchen Arbeitszyklus könnte ansonsten zu massiven Fehlern bei der Wiederaufnahme dieses Zyklus führen und das betreffende Werkstück und/oder Werkzeug unbrauchbar machen. Darüber hinaus gilt für derartige Vorrichtungen, dass sie möglichst flach bauen sollen, damit die Vorrichtungen möglichst im Maschinenbett untergebracht werden können und die betroffenen Stoffe allein durch die Schwerkraft in die Vorrichtung zum Abtransport gelangen können.Accordingly, high safety requirements are to be placed on devices for the removal of chips and coolant, which avoid the leakage of the affected substances with high reliability. In particular, these devices must ensure that in the event of an emergency shutdown of the removal of the substances mentioned, for example due to blockages, a sufficient storage volume can still be taken up in the discharge lines until a complete processing cycle of the respective machine can be completed. Interrupting such a work cycle could otherwise lead to massive errors when resuming this cycle and render the workpiece and / or tool in question unusable. In addition, it applies to devices of this type that they should be as flat as possible so that the devices can be accommodated in the machine bed as far as possible and the substances concerned can get into the device for removal solely by gravity.
Die Aufgabe der vorliegenden Erfindung besteht demnach insbesondere darin, eine flach bauende Vorrichtung der eingangs erwähnten Art zu schaffen, der die hier betroffenen Stoffe im Maschinenbett allein aufgrund der Schwerkraft dieser Stoffe zufallen und die bei dieser räumlichen Begrenztheit ausreichend Speicherraum zur Verfügung stellen, so dass bei Unterbrechung des Abtransports die Menge der anfallenden Stoffe zumindest so lange sicher aufgenommen werden kann, bis die Werkzeugmaschine einen vollen Arbeitszyklus beendet hat und abgeschaltet werden kann.The object of the present invention is therefore, in particular, to provide a flat-construction device of the type mentioned, to which the substances concerned here in the machine bed fall solely due to the gravity of these substances and which, given this spatial limitation, provide sufficient storage space, so that at Interrupting the removal, the amount of the resulting substances can be safely absorbed at least until the machine tool has completed a full work cycle and can be switched off.
Diese Aufgabe wird bei einer Vorrichtung der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, dass eine in den unteren Bereich einer Werkzeugmaschine unterhalb des Späne- und Kühlmittelaustritts dieser Maschine einsetzbare kanalartige Aufnahme vorgesehen ist, dass die Aufnahme aus einer inneren Rinne und einer äußeren Rinne gebildet ist, wobei die äußere Rinne die innere Rinne mit Abstand umschließt, dass in den Seitenwänden der inneren Rinne für Kühlmittel Überströmöffnungen zur äußeren Rinne vorgesehen sind, dass die Rinnen an ihrem einen Ende jeweils geschlossen und an ihrem anderen offen sind, wobei das offene Ende der inneren Rinne auf Eintrittsniveau eines Spänezerkleinerers oder darüber und das offene Ende der äußeren Rinne unterhalb des Eintrittsniveaus des Spänezerkleinerers in ein Transportsystem für den gemeinsamen Weitertransport von gegebenenfalls zerkleinerten Spänen und Kühlmittel eintritt.This object is achieved according to the invention in a device of the type mentioned at the outset by providing a channel-like receptacle which can be inserted into the lower region of a machine tool below the swarf and coolant outlet of this machine, that the receptacle is formed from an inner groove and an outer groove, wherein the outer groove surrounds the inner groove at a distance, that in the side walls of the inner groove for coolant overflow openings to the outer groove are provided, that the grooves are closed at one end and open at the other, the open end of the inner groove at the entry level of a chip shredder or above and the open end of the outer channel below the entry level of the chip shredder enters a transport system for the joint further transport of optionally shredded chips and coolant.
Wenn also bei einer solchen Vorrichtung das Niveau des Kühlmittels in der inneren Rinne zumindest eine der Überströmöffnungen zur äußeren Rinne erreicht, tritt die Kühlflüssigkeit, die noch kleine Späne enthalten kann, in die äußere Rinne über, während die in der inneren Rinne verbleibenden Späne und Kühlflüssigkeit in den Spänezerkleinerer geführt werden. Das Kühlmittel, welches sich in der äußeren Rinne befindet, gelangt dann unterhalb des Spänezerkleinerers in das Transportsystem der Vorrichtung, passiert also den Spänezerkleinerer nicht.In such a device, therefore, if the level of the coolant in the inner groove reaches at least one of the overflow openings to the outer groove, the cooling liquid, which may still contain small chips, passes into the outer groove, while the chips and cooling liquid remaining in the inner groove into the chip shredder. The coolant that is in the outer groove is then gets below the chip shredder into the transport system of the device, so does not pass the chip shredder.
Wenn ein Spänestau allein in der inneren Rinne oder im Spänezerkleinerer vorliegt, so wird die Menge der aus der inneren Rinne durch die Uberströmöffnungen in die äußere Rinne gelangenden Kühlflüssigkeit zunehmen. Diese Menge wird aber dann, wenn das dem Spänezerkleinerer nachgeordnete Transportsystem und darin insbesondere die Pumpe weiter arbeitet, ohne weiteres aufgenommen und abgefördert werden. Allein wenn der Pumpenbetrieb unterbrochen wird kommt es zwingend zu einem Stau. In einem solchen Fall steht aber ein hohes Speichervolumen zur Verfügung, das die beiden Rinnen und darüber hinaus den Raum des Transportsystems bis zur Pumpe umfasst. Somit wird auch in solchen Störungsfällen die Aufnahme von Spänen und Kühlflüssigkeit über den Ablauf der Arbeitszykluszeit der zugeordneten Werkzeugmaschine sichergestellt werden können.If there is a chip jam alone in the inner channel or in the chip shredder, the amount of the cooling liquid coming from the inner channel through the overflow openings into the outer channel will increase. However, if the transport system downstream of the chip shredder and in particular the pump continues to work, this quantity will be readily picked up and removed. Only if the pump operation is interrupted there is a traffic jam. In such a case, however, there is a large storage volume available, which encompasses the two channels and also the space of the transport system up to the pump. In this way, the absorption of chips and coolant over the expiry of the working cycle time of the assigned machine tool can also be ensured in such malfunctions.
Die erfindungsgemäße Vorrichtung kann dabei so gefahren werden, dass Kühlmittel nur dann über die Uberströmöffnungen in die äußere Rinne gelangt, wenn ein vollständiger Abtransport z.B., aufgrund von Stauungen, ansonsten nicht mehr gewährleistet wäre. Es ist aber auch möglich, mit der erfindungsgemäßen Vorrichtung so zu arbeiten, dass ständig, also auch im normalen Betriebszustand, ein Teil des Kühlmittels über die Überströmöffnungen der äußeren Rinne zugeführt wird. Die beim Durchtritt durch die Überströmöffnungen etwa noch mitgeschwemmten Späne sind klein, da sich größere Späne als Sediment in der inneren Rinne absetzen und auch von den Überströmöffnungen zurückgehalten werden. Die in der äußeren Rinne mitgeführten Späne müssen für den weiteren Transport nicht dem Zerkleinerer zugeführt werden.The device according to the invention can be driven in such a way that coolant only reaches the outer channel via the overflow openings if complete removal, for example due to congestion, would otherwise no longer be guaranteed. However, it is also possible to work with the device according to the invention in such a way that part of the coolant is continuously supplied to the outer channel via the overflow openings, ie also in the normal operating state. The chips that are still washed away when passing through the overflow openings are small, since larger chips settle as sediment in the inner channel and are also retained by the overflow openings. The chips carried in the outer channel do not have to be fed to the shredder for further transport.
Erfindungsgemäß wird vorgeschlagen, dass zumindest die innere Rinne einen in Transportrichtung geneigten Boden hat, so dass der Transport des darin enthaltenen Materials ohne zusätzlichen Einsatz und ohne zusätzlichen Maßnahmen erfolgen kann.It is proposed according to the invention that at least the inner channel has a bottom which is inclined in the transport direction, so that the material contained therein can be transported without additional use and without additional measures.
Es wird erfindungsgemäß weiter vorgeschlagen, dass zumindest in der inneren Rinne Mittel zur mechanischen Unterstützung des Transports der Späne vorgesehen sind. Ferner kann zumindest die innere Rinne mit einem Spülanschluss zur Unterstützung des Transports der Späne versehen sein.It is further proposed according to the invention that means for mechanical support for the transport of the chips are provided at least in the inner groove. Furthermore, at least the inner channel can be provided with a rinsing connection to support the transport of the chips.
Die Erfindung sieht weiter vor, dass die innere und die äußere Rinne im Bereich ihrer oberen Ränder mit Ausnahme der Uberströmöffnungen dichtend aneinander angeschlossen sein können. Dadurch kann insbesondere das unerwünschte Austreten von Kühlmittel vermieden werden.The invention further provides that the inner and the outer channel can be connected to one another in a sealing manner in the region of their upper edges, with the exception of the overflow openings. As a result, the undesirable leakage of coolant can be avoided.
Gemäß einem weiteren Vorschlag der Erfindung kann vorgesehen sein, dass die innere und/oder die äußere Rinne im Einbauzustand dichtend am Rand des Späne- und Kühlmittelaustritts aus der Werkzeugmaschine anliegt. Auch dies dient der zuverlässigen Übernahme der aus der Maschine austretenden Stoffe durch die erfindungsgemäße Vorrichtung.According to a further proposal of the invention, it can be provided that the inner and / or the outer groove, in the installed state, lies sealingly against the edge of the chip and coolant outlet from the machine tool. This also serves to reliably take over the substances emerging from the machine by the device according to the invention.
Weiter sieht ein Vorschlag der Erfindung vor, dass am oberen Rand der äußeren Rinne Einlassöffnungen für die Aufnahme von Leckagen im Bereich des Maschinenbetts vorgesehen sind.Furthermore, a proposal of the invention provides that inlet openings are provided on the upper edge of the outer channel for absorbing leaks in the area of the machine bed.
Einem weiteren Vorschlag der Erfindung entsprechend sind in Transportrichtung die Uberströmöffnungen in den Wänden der inneren Rinne hintereinander höhengestuft angeordnet. Auf diese Weise kann leicht erfasst werden, welchen Auslastungsgrad die Rinnen zur Zeit aufweisen. Auf diese Weise kann auch entsprechend angepasst die Zahl der freien Uberströmöffnungen und damit die Menge der überströmenden Flüssigkeit erkannt werden.According to a further proposal of the invention, the overflow openings in the walls of the inner channel are arranged one behind the other in a height-graded manner in the transport direction. In this way it is easy to determine the degree of utilization of the channels at the moment. In this way, the number of free overflow openings and thus the amount of overflowing liquid can also be recognized accordingly.
Schließlich sieht die erfindungsgemäße Vorrichtung vor, dass das Transportsystem einen die Späne vorwärts schiebenden und einer Pumpe zuführenden Kratzer aufweist, und die Späne und die Kühlflüssigkeit durch Pumpen zur weiteren Entsorgung weitergeführt werden.Finally, the device according to the invention provides that the transport system has a scratch pushing the chips forward and feeding them to a pump, and the chips and the coolant are carried on by pumps for further disposal.
Im folgenden Teil der Beschreibung wird eine Ausführungsform der erfindungsgemäßen Vorrichtung anhand von Zeichnungen beschrieben. Es zeigt:In the following part of the description, an embodiment of the device according to the invention is described with reference to drawings. It shows:
Figur 1 Eine perspektivische Ansicht einer Ausführungsform der erfindungsgemäßen Vorrichtung mit schematisch angedeuteter Werkzeugmaschine,1 shows a perspective view of an embodiment of the device according to the invention with a schematically indicated machine tool,
Figur 2 eine Seitenansicht auf die Vorrichtung gemäß Figur 1 undFigure 2 is a side view of the device of Figure 1 and
Figur 3 eine Detailansicht auf eine erfindungsgemäße Ausbildung von äußerer und innerer Rinne.Figure 3 is a detailed view of an inventive design of outer and inner gutter.
In den Figuren 1 und 2 ist eine Werkzeugmaschine 1 schematisch angedeutet, deren Maschinenbett eine Öffnung 2 aufweist. Bei der Werkzeugmaschine 1 handelt es sich um eine spanende Maschine beliebiger Ausführung und Zweckbestimmung. In die Öffnung 2 ragt eine u-förmige innere Rinne 3 hinein, die wiederum in einer ebenfalls u- förmigen äußeren Rinne 4 platziert ist. Die Seitenwände 5 und der Boden 6 der inneren Rinne einerseits und die Seitenwände 7 sowie der Boden 8 der äußeren Rinne andererseits sind mit Abstand voneinander angeordnet, so dass der Gesamtquerschnitt der äußeren Rinne 4 wesentlich größer ist als der Querschnitt der inneren Rinne 3. Dies bedeutet, dass der gesamte Rinnenquerschnitt dann, wenn die innere Rinne und die äußere Rinne 4 wirksam gemacht werden, im Wesentlichen dem Gesamtquerschnitt der äußeren Rinne 4 entspricht. Der obere Rand 9 der inneren Rinne 3 ist schräg nach außen abgekantet und dort mit dem oberen Rand 10 der äußeren Rinne 4 verbunden. In der Abkantung befinden sich Durchlässe 11 für zur Abfuhr von möglichen Leckagen aus dem Maschinenbett. Ferner ist die Abkantung mit einer Dichtung 12 versehen, die ein dichtendes Zusammenarbeiten zwischen der inneren Rinne 3 einerseits und einer Ablaufkante 13 des Maschinenbettes herstellt.1 and 2, a machine tool 1 is indicated schematically, the machine bed of which has an opening 2. The machine tool 1 is a cutting machine of any design and purpose. A u-shaped inner channel 3 protrudes into the opening 2, which in turn is placed in a likewise u-shaped outer channel 4. The side walls 5 and the bottom 6 of the inner gutter on the one hand and the side walls 7 and the bottom 8 of the outer gutter on the other hand are arranged at a distance from one another, so that the overall cross section of the outer gutter 4 is substantially larger than the cross section of the inner gutter 3. This means that the entire channel cross-section, when the inner channel and the outer channel 4 are made effective, essentially corresponds to the total cross-section of the outer channel 4. The upper edge 9 of the inner groove 3 is bent obliquely outwards and is connected there to the upper edge 10 of the outer groove 4. In the fold there are passages 11 for the removal of possible leaks from the machine bed. Furthermore, the fold is provided with a seal 12, which creates a sealing cooperation between the inner channel 3 on the one hand and a trailing edge 13 of the machine bed.
Die innere Rinne 3 und die äußere Rinne 4 sind an ihren rückwärtigen Enden geschlossen.The inner groove 3 and the outer groove 4 are closed at their rear ends.
Im Bereich der oberen Seitenwand 5 der inneren Rinne 3 sind Überströmöffnungen 14 vorgesehen, durch die Kühlmittel aus der inneren Rinne 3 in die äußere Rinne 4 überlaufen kann, wenn der Kühlmittelstand einen entsprechenden Pegel erreicht hat. Die Überströmöffnungen 14 sind in Transportrichtung hintereinander angeordnet und dabei in ihrer Höhe gegeneinander versetzt. Dies bedeutet, dass die Zahl der angesprochenen Überströmöffnungen mit steigendem Pegel zunimmt. Daraus ergibt sich eine Füllstandsanzeige, die z.B. auf beginnende bzw. vorliegende Verstopfungen in der inneren Rinne 3 hinweist. Entsprechende Überwachungsgeräte können einzelnen oder allen Überströmöffnungen zugeordnet sein. Die Uberströmöffnungen sind so platziert und dimensioniert, dass sie aus dem Späne-Kühlmittel-Gemisch - erforderlichenfalls unter Einsatz von Sieben in den Überströmöffnungen - im Wesentlichen nur das Kühlmittel hindurchtreten lassen. Durch Überwachung der Überströmöffnungen kann festgestellt werden, ob bzw. welche dieser Öffnungen durchströmt werden. Daraufhin wiederum kann - wenn gewünscht - steuernd in das Verfahren der Vorrichtung oder sogar der Werkzeugmaschine eingegriffen werden.In the area of the upper side wall 5 of the inner channel 3, overflow openings 14 are provided, through which coolants from the inner channel 3 into the outer channel 4 can overflow when the coolant level has reached a corresponding level. The overflow openings 14 are arranged one behind the other in the transport direction and their height is offset from one another. This means that the number of overflow openings addressed increases with increasing level. This results in a level indicator, which indicates, for example, the beginning or existing blockages in the inner channel 3. Corresponding monitoring devices can be assigned to individual or to all overflow openings. The overflow openings are placed and dimensioned such that they essentially only allow the coolant to pass out of the swarf-coolant mixture - if necessary using sieves in the overflow openings. By monitoring the overflow openings, it can be determined whether or which of these openings are being flowed through. Thereupon in turn, if desired, control intervention can be made in the method of the device or even the machine tool.
Der Boden 6 der inneren Rinne 3 ist in Transportrichtung geneigt und endet an seinem in Figur 2 rechts liegenden Ende auf dem Eintrittsniveau eines Spänezerkleinerers 15 oder leicht darüber.The bottom 6 of the inner channel 3 is inclined in the transport direction and ends at its end lying on the right in FIG. 2 at the entry level of a chip shredder 15 or slightly above it.
Der Boden 8 endet unterhalb des Eintrittsniveaus des Spänezerkleinerers 15, so dass in der äußeren Rinne 4 geführtes Kühlmittel in ein Transportsystem 16 mündet, in dem die Kühlflüssigkeit wieder mit den durch den Spänezerkleinerer 15 geführten und dort gegebenenfalls weiter zerkleinerten Spänen wieder vereinigt wird. Hier wird das so gebildete Gemisch von einem Kratzer 17 dem Einlauf 18 einer Pumpe zugeführt und von dort zur weiteren Behandlung weiter befördert.The bottom 8 ends below the entry level of the chip shredder 15, so that coolant guided in the outer channel 4 opens into a transport system 16, in which the cooling liquid is again combined with the chips guided through the chip shredder 15 and possibly further shredded there. Here, the mixture formed in this way is fed from a scratch 17 to the inlet 18 of a pump and from there is conveyed on for further treatment.
Das Gemisch aus Spänen und Kühlmittel kann in der inneren Rinne allein aufgrund des vorhandenen Gefälles dieser Rinne abfließen. Eine Unterstützung des Abfließens kann durch Einbringen von zusätzlicher Spülflüssigkeit oder durch mechanische Mittel gefördert werden. Entsprechendes gilt auch für die äußere Rinne 4. BezugszeichenlisteThe mixture of chips and coolant can flow off in the inner channel solely due to the incline of this channel. Aiding the drainage can be promoted by introducing additional rinsing liquid or by mechanical means. The same applies to the outer channel 4. LIST OF REFERENCE NUMBERS
