Description

Die Erfindung betrifft eine Ausdrückrolle, die einen in axialer Richtung verlaufenden Grundkörper aufweist, wobei auf dem Grundkörper der Ausdrückrolle mindestens ein in axialer Richtung helixartig verlaufendes Walkelement angeordnet ist.The invention relates to a Ausdrückrolle having a running in the axial direction of the base body, wherein on the base of the Ausdrückrolle at least one helically extending in the axial direction Walk element is arranged.

Eine derartige Ausdrückrolle ist aus der DE 813 840 bekannt.Such Ausdrückrolle is from the DE 813 840 known.

Ausdrückrollen werden unter anderem in einem Reinigungsbehälter zur Reinigung von Werkzeugen mit einer Flüssigkeit aufnehmenden Arbeitsauflage, insbesondere von Ausfugbrettern mit einem entsprechenden ABS-Belag, z. B. einem Moosgummibelag, verwendet. Die eine glatte oder eine quergeriffelte Oberfläche aufweisenden bekannten Ausdrückrollen besitzen den Nachteil, dass aufgrund der hierbei auftretenden Flächenpressung zwischen der Ausdrückrolle und der flächigen Arbeitsauflage des zu reinigenden Werkzeugs nur ein unzufriedenstellender Flüssigkeitsaustrag aus der Arbeitsauflage gegeben ist. Außerdem besitzen die bekannten Ausdrückrollen den Nachteil, dass beim Reinigen der Werkzeuge die aus dem Werkzeug austretende Flüssigkeit, insbesondere Wasser, nicht vollständig in den Reinigungsbehälter abgeleitet wird, so dass in nachteiliger Art und Weise neben dem Behälter Lachen der Flüssigkeit auftreten.Ausdrückrollen are, inter alia, in a cleaning container for cleaning tools with a liquid-receiving work support, in particular Ausfugbrettern with a corresponding ABS coating, z. B. a foam rubber coating, used. The smooth or cross-ribbed surface having known Ausdrückrollen have the disadvantage that due to the surface pressure occurring between the Ausdrückrolle and the flat work support of the tool to be cleaned only an unsatisfactory liquid discharge is given from the work support. In addition, the known Ausdrückrollen have the disadvantage that when cleaning the tools emerging from the tool liquid, especially water, is not completely dissipated in the cleaning tank, so that occur in a disadvantageous manner next to the container laughing the liquid.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Ausdrückrolle der eingangs genannten Art derart weiterzubilden, dass ein verbesserter Flüssigkeitsaustrag aus dem zu reinigenden Werkzeug gegeben ist.It is therefore an object of the present invention, a Ausdrückrolle the aforementioned type such that an improved liquid discharge is given from the tool to be cleaned.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Grundkörper der Ausdrücktolle durch mindestens einen axial verlaufenden Steg ausgebildet ist, auf dem oder denen das oder die Walkelemente angeordnet sind.This object is achieved in that the main body of the Ausdrücktolle is formed by at least one axially extending web on which or which or the Walk elements are arranged.

Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Art und Weise eine insbesondere für Reinigungsbehalter geeignete Ausdrückrolle geschaffen, die sich dadurch auszeichnet, dass ein verbesserter Flüssigkeitsaustrag aus der Arbeitsauflage des zu reinigenden Werkzeugs gegeben ist. Dies wird dadurch erreicht, dass infolge der Rotationsbewegung der Ausdrockrolle beim Reinigungsvorgang durch das mindestens eine Walkelement eine Walkbeaufschlagung der Arbeitsauflage erzielt wird. Erfindungsgemäß ist vorgesehen, dass der Grundkörper der erfindungsgemäßen Ausdrückrolle durch mindestens einen in axialer Richtung verlaufenden Steg ausgebildet ist, auf dem oder auf denen das mindestens eine helixartige Walkelement angeordnet ist. Eine derartige gitterartige Ausbildung der erfindungsgemäßen Ausdrückrolle besitzt den Vorteil, dass die aus der Arbeitsauflage des zu reinigenden Werkzeugs herausgewalkte Flüssigkeit unmittelbar nach ihrem Austrag in den Reinigungsbehälter abtropfen kann und nicht mehr zu den Enden der Ausdrückrolle geleitet wird. Der Bildung von Lachen neben dem Reinigungsbehafter wird hierdurch in vorteilhafter Art und Weise entgegengewirkt.By means of the measures according to the invention, a squeezing roller, in particular suitable for cleaning containers, is provided in an advantageous manner, which is characterized in that an improved liquid discharge from the working support of the tool to be cleaned is provided. This is achieved in that as a result of the rotational movement of the Ausdrockrolle during the cleaning process by the at least one Walkelement a Walkbeaufschlagung the work support is achieved. According to the invention, it is provided that the main body of the ejection roller according to the invention is formed by at least one web extending in the axial direction, on which or on which the at least one helical milling element is arranged. Such a grid-like design of the ejection roller according to the invention has the advantage that the herausgewalkte from the work surface of the tool to be cleaned fluid can drain immediately after their discharge into the cleaning container and no longer directed to the ends of the ejection roller. The formation of laughter next to the Reinigungsbehafter is thereby counteracted in an advantageous manner.

Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass die erfindungsgemäße Ausdrückrolle zwei entgegengesetzt und vorzugsweise zur Mitte der Ausdrückrolle hin orientierte Walkelemente aufweist. Eine derartige Ausgestaltung besitzt den Vorteil, dass hierdurch eine Ableitung der aus dem Arbeitsbelag des zu reinigenden Werkzeugs herausgewalkten Flüssigkeit in den Mittelbereich des die erfindungsgemäße Ausdrückrolle aufnehmenden Reinigungsbehälters gegeben ist.An advantageous development of the invention provides that the ejection roller according to the invention has two opposite and preferably to the center of the ejector out oriented walker elements. Such a configuration has the advantage that in this way a derivation of the out of the working surface of the tool to be cleaned out-flowed liquid is given in the central region of the inventive Ausdrückrolle receiving cleaning tank.

Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, dass die erfindungsgemäße Ausdrückrolle an mindestens einem Ende des Grundkörpers ein Sperrelement mit einem größeren Durchmesser als der Durchmesser des Grundkörpers in diesem Bereich aufweist. Eine derartige Maßnahme besitzt den Vorteil, dass hierdurch das Austreten von aus dem zu reinigenden Werkzeug herausgewalkter Flüssigkeit aus der Ausdrückrolle und somit der Bildung von Lachen neben dem Reinigungsbehälter entgegengewirkt wird.A further advantageous development of the invention provides that the ejection roller according to the invention has at least one end of the base body a blocking element with a larger diameter than the diameter of the base body in this area. Such a measure has the advantage that, as a result, the escape of liquid which has dried out from the tool to be cleaned from the ejection roller and thus the formation of pools next to the cleaning container is counteracted.

Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, dass zwischen dem Sperrelement der Ausdrückrolle und dem Beginn des Walkelements in axialer Richtung ein Zwischenraum vorhanden ist. Eine derartige Maßnahme besitzt den Vorteil, dass die durch das Walkelement herausgewalkte Flüssigkeit nicht durch die zwischen den Windungen des Walkelements befindlichen Vertiefungen zum Sperrelement der Ausdrückrolle geleitet wird, sondern spätestens in dem zwischen dem Beginn des Walkelements und des Sperrelements befindlichen Zwischenraum in den Reinigungsbehälter ablaufen kann.A further advantageous embodiment of the invention provides that between the locking element of the ejection roller and the beginning of the Walkelements in the axial direction, a gap is present. Such a measure has the advantage that the herausgewalkte by the walker liquid is not passed through the recesses located between the turns of the walker element to the blocking element of the Ausdrückrolle, but can run at least in the space between the beginning of the Walkelements and the locking element intermediate space in the cleaning container ,

Eine weitere vorteilhafte Weiterbildung der Erfindung sieht vor, dass der Grundkörper stangen- oder rohrförmig ausgebildet ist, und dass die mindestens ein helixartiges Walkelement auf der Oberfläche des stangen- oder rohrförmigen Grundkörpers aufgesetzt ist. Eine derartige Maßnahme besitzt den Vorteil, dass hierdurch eine, insbesondere gegen ein Durchbiegen, besonders stabile Ausdrückrolle ausgebildet wird.A further advantageous development of the invention provides that the main body is rod-shaped or tubular, and that the at least one helix-like walker element on the surface of the rod-shaped or tubular body is attached. Such a measure has the advantage that in this way one, in particular against bending, particularly stable ejection roller is formed.

Weitere vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche,Further advantageous developments of the invention are the subject of the subclaims,

In den Figuren 1 bis 4 ist nun eine allgemein mit 1 bezeichnete Ausdrückrolle dargestellt. Die Ausdrückrolle 1 weist einen sich in axialer Richtung erstreckenden Grundkörper 2 mit im wesentlichen kreisförmigem Querschnitt auf. Der Grundkörper 2 ist im hier gezeigten Fall rohrförmig ausgebildet und weist eine Durchtrittsbohrung 3 auf, in die in den Figuren nicht gezeigte Lagerachsen einbringbar sind, welche dazu dienen, die Ausdrückrolle 1 in einem Reinigungsbehälter zu befestigen.In the FIGS. 1 to 4 is now shown a generally designated 1 ejector role. The Ausdrückrolle 1 has a body 2 extending in the axial direction with a substantially circular Cross-section on. The base body 2 is formed tubular in the case shown here and has a passage bore 3, in the bearing shafts, not shown in the figures are introduced, which serve to fasten the squeezing roller 1 in a cleaning container.

Auf dem Grundkörper 2 der Ausdrückrolle 1 sind nun zwei gegenläufig orientierte Walkelemente 4a und 4b angeordnet, welche - wie am besten aus den Figuren 1 und 2 ersichtlich ist - in axialer Richtung einen helixartigen Verlauf aufweisen. Die beiden Walkelemente 4a, 4b sind hierbei durch ein Mittelelement 4c getrennt. Wird nun das zu reinigende Werkzeug über die Ausdrückrolle 1 gezogen, so wird diese hierdurch in Rotation gesetzt. Dies bewirkt eine Walkbewegung der helixartig angeordneten Walkelemente 4a, 4b der Ausdrückrolle 1. Die dadurch bewirkte Walkbeaufschlagung der Arbeitsauflage des zu reinigenden Werkzeugs bewirkt hierbei einen verbesserten Flüssigkeitsaustrag aus der Arbeitsauflage, da nun nicht mehr - wie bei den bekannten Ausdrückrollen - eine dem Flüssigkeitsaustrag hinderliche Flächenpressung zwischen Ausdrückrolle 1 und Arbeitsauflage stattfindet, sondern daß in vorteilhafter Art und Weise ein bestimmter Flächenbereich der Arbeitsauflage periodisch von den einzelnen Windungen 4a', 4b' des entsprechenden helixartigen Walkelements 4a, 4b beaufschlagt wird, wobei gleichzeitig die durch diese Beaufschlagung aus der Arbeitsauflage herausgewalkte Flüssigkeit in die zwei benachbarte Windungen 4a', 4b' des jeweiligen Walkelements 4a, 4b trennende Vertiefung 7 abgeleitet wird.On the main body 2 of the Ausdrückrolle 1 now two counter-oriented walker elements 4a and 4b are arranged, which - as best of the Figures 1 and 2 is apparent - have a helical course in the axial direction. The two walker elements 4a, 4b are hereby separated by a central element 4c. If now the tool to be cleaned is pulled over the ejection roller 1, this is thereby set in rotation. This causes a Walk movement of the helically arranged Walk elements 4a, 4b of the Ausdrückrolle 1. The effect caused by Walkbeaufschlagung the work support of the tool to be cleaned in this case an improved liquid discharge from the work support, since now no longer - as in the known Ausdrückrollen - a liquid discharge hindering surface pressure takes place between Ausdrückrolle 1 and work rest, but that in an advantageous manner, a certain surface area of the work support periodically from the individual turns 4a ', 4b' of the corresponding helical Walk elements 4a, 4b is acted upon, at the same time herausgewalkte by this imposition of the work support liquid in the two adjacent turns 4a ', 4b' of the respective Walkelements 4a, 4b separating recess 7 is derived.

Dem Fachmann ist klar ersichtlich, daß er die Steigung der helixartigen Walkelemente 4a, 4b dem jeweils gewünschten Einsatzzweck in weiten Bereichen anpassen kann, wobei bevorzugt wird, daß zwischen der Axialrichtung der Ausdrückrolle 1 und den einzelnen Windungen der helixartigen Walkelemente 4a, 4b ein stumpfer Winkel gegeben ist.It is clear to the person skilled in the art that he can adapt the pitch of the helical flexing elements 4a, 4b to the desired application in a wide range, it being preferred that an obtuse angle exists between the axial direction of the ejection roller 1 and the individual turns of the helical flexing elements 4a, 4b given is.

Im hier gezeigten Fall sind die beiden Walkelemente 4a, 4b, als umlaufende Stege 6 ausgebildet, die eine im wesentlichen ebene Oberfläche 6' aufweisen. Eine derartige Ausbildung der Walkelemente 4a, 4b besitzt den Vorteil, daß hierdurch ein verbessertes Herauswalken der Flüssigkeit aus der Arbeitsauflage, insbesondere einer Schaumauflage, des Werkzeugs, gegeben ist, da das Werkzeug auf der Ausdrückrolle 1 in vorteilhafter Art und Weise im wesentlichen nurmehr auf der Oberfläche 6 der beiden Walkelemente 4a, 4b aufsetzt, wodurch ein höherer Arbeitsdruck gegeben ist als bei einer großflächigen Auflage, wie dies bei den bekannten Ausdrückrollen, die nur eine glatte oder eine geriffelte, ansonsten aber unstrukturierte Oberfläche aufweisen.In the case shown here, the two rolling elements 4a, 4b, as peripheral webs 6 are formed, which have a substantially planar surface 6 '. A Such training of the Walk elements 4a, 4b has the advantage that this is an improved herauswalken the liquid from the work support, in particular a foam pad, the tool is given, since the tool on the Ausdrückrolle 1 in an advantageous manner substantially only on the surface 6 of the two Walk elements 4a, 4b touches, whereby a higher working pressure is given as in a large-scale edition, as in the known Ausdrückrollen having only a smooth or a corrugated, but otherwise unstructured surface.

Die beiden Helixstrukturen der Walkelemente 4a, 4b sind dabei jeweils derart orientiert, daß sie zur Mitte M der Ausdrückrolle 1, also zum Mittelelement 4c, hin gerichtet sind. Diese derart orientierte Anordnung dient dazu, daß eine in der Arbeitsauflage, insbesondere der Schwammauflage, des zu reinigenden Werkzeugs, insbesondere eines Ausfugbrettes, aufgenommene Flüssigkeit, insbesondere Wasser, beim Herauswalken dieser Flüssigkeit aus der Arbeitsauflage zur Mitte M der Ausdrückrolle 1 hin geleitet wird. Hierdurch wird bereits in vorteilhafter Art und Weise der Bildung von Lachen der aus der Arbeitsauflage des Werkzeugs herauszuwalkenden Flüssigkeit außerhalb des Reinigungsbehälters entgegengewirkt.The two helix structures of the flexing elements 4a, 4b are each oriented such that they are directed towards the center M of the ejection roller 1, ie to the central element 4c. This arrangement oriented in this way serves to guide a liquid, in particular water, taken up in the work support, in particular the sponge support, of the tool to be cleaned, in particular a Ausfugbrettes, out of the work support to the center M of the ejection roller 1 when this fluid is being forced out. As a result, the formation of pools of liquid to be moved out of the working support of the tool outside the cleaning container is already counteracted in an advantageous manner.

Vorzugsweise ist desweiteren noch vorgesehen, daß die Ausdrückrolle 1 an jedem ihrer Enden 1' und 1" ein Sperrelement 10 aufweist, dessen Durchmesser größer als der Durchmesser des Grundkörpers 2 der Ausdrückrolle 1 in diesem Bereich ist. Die Sperrelemente 10 bilden in vorteilhafter Art und Weise somit Barrieren aus, welche verhindern, daß die aus der Arbeitsauflage des zu reinigenden Werkzeugs herausgewalkte Flüssigkeit in axialer Richtung aus der Ausdrückrolle 1 herausläuft. Vorzugsweise ist hierbei desweiteren vorgesehen, daß - wie am besten aus Figur 3 ersichtlich ist - zwischen dem äußeren Ende 4a', 4b' eines jeden Walkelements 4a, 4b und dem Innenrand des Sperrelements 10 ein Zwischenraum 11 ausgebildet ist, welcher bewirkt, daß die in den Vertiefungen 7 zwischen den Stegen 6 befindliche Flüssigkeit nicht durch die Rotationsbewegung der Ausdrückrolle 1 bis zum Sperrelement 10 hin geleitet werden kann, sondern spätestens im Zwischenraum 11 in den Reinigungsbehälter abläuft.Preferably, it is further provided that the squeezing roller 1 has at each of its ends 1 'and 1 "a locking element 10 whose diameter is greater than the diameter of the base body 2 of the squeezing roller 1 in this area Thus, from barriers which prevent the liquid herausgewalkte from the work support of the tool to be cleaned runs out in the axial direction of the Ausdrückrolle 1. Preferably here is further provided that - as best of FIG. 3 it can be seen - between the outer end 4a ', 4b' of each Walk element 4a, 4b and the inner edge of the locking element 10, a gap 11 is formed, which causes the fluid located in the recesses 7 between the webs 6 is not through the Rotary movement of the ejector roller 1 can be passed to the blocking element 10 out, but at least in the intermediate space 11 runs into the cleaning container.

Weiter oben wurde ausgeführt, daß die beiden Walkelemente 4a, 4b und gegebenenfalls das Mittelelement 4c auf den Grundkörper 2 der Ausdrückrolle 1 aufgesetzt sind. Dies bedeutet nicht zwangsläufig, daß die Elemente 4a, 4b, 4c und der Grundkörper 2 aus unterschiedlichen Bauteilen bestehen, obwohl dies natürlich auch möglich ist. Im hier gezeigten Fall der Walkelemente 4a, 4b und des Mittelelements 4c bilden diese Elemente 4a, 4b, 4c und der Grundkörper 2 integrale Bestandteile der Ausdrückrolle 1, wobei die Walkelemente 4a, 4b vorzugsweise derart ausgebildet werden, daß in eine stangen- oder rohrförmige Ausdrückrolle 1 die Vertiefungen 7 zur Ausbildung der die Walkelemente 4a, 4b ausbildenden Stege 6 eingefräst werden. Es ist aber natürlich auch möglich, die beschriebene Ausdrückrolle 1 als Spritzgußteil herzustellen.It was further stated above that the two walker elements 4a, 4b and possibly the central element 4c are placed on the main body 2 of the ejection roller 1. This does not necessarily mean that the elements 4a, 4b, 4c and the main body 2 consist of different components, although of course this is also possible. In the case of the walk elements 4a, 4b and the middle element 4c shown here, these elements 4a, 4b, 4c and the main body 2 form integral parts of the ejection roller 1, wherein the flexing elements 4a, 4b are preferably designed such that in a rod-shaped or tubular ejection roller 1, the recesses 7 are milled for forming the web elements 4a, 4b forming webs 6. But it is of course also possible to produce the described Ausdrückrolle 1 as an injection molded part.

Beim obigen Beispiel wurde davon ausgegangen, daß die Ausdrückrolle 1 zwei entgegengesetzt orientierte, helixartige Walkelemente 4a, 4b aufweist. Eine derartige Ausbildung wird zwar bevorzugt, ist aber nicht zwingend. Vielmehr ist es möglich, mehr als zwei Walkelemente 4a, 4b vorzusehen oder das Mittelelement 4c entfallen zu lassen. Z. B. ist es denkbar, daß ein erstes Walkelement 4a von dem ersten äußeren Ende 1' der Ausdrückrolle 1 bis zur Mitte M hin reichend angeordnet ist, und daß in der zweiten Hälfte, also im Bereich von der Mitte M zum zweiten Ende 1" der Ausdrückrolle 1, wiederum zwei entgegengesetzt orientierte Walkelemente angeordnet sind. Bei einer derartigen Ausgestaltung wird dann ein Teil der Flüssigkeit zur Mitte M und ein anderer Teil der Flüssigkeit zu der "Mitte" der beiden weiteren, entgegengesetzt orientierten Walkelemente hin geleitet, so daß also eine Verteilung der ausgewalkten Flüssigkeit über den Querschnitt des Reinigungsbehälters erfolgt.In the above example, it has been assumed that the ejection roller 1 has two oppositely oriented helical flexing elements 4a, 4b. Although such training is preferred, it is not mandatory. Rather, it is possible to provide more than two walker elements 4a, 4b or to omit the middle element 4c. For example, it is conceivable that a first rolling element 4a is arranged ranging from the first outer end 1 'of the Ausdrückrolle 1 to the center M, and that in the second half, ie in the range from the center M to the second end 1 "of the Ausdrückrolle 1, in turn, two oppositely oriented walker elements are arranged .. In such an embodiment, a portion of the liquid to the center M and another part of the liquid to the "center" of the two other, oppositely oriented Walk elements out, so that so a distribution of ausgealkten liquid over the cross section of the cleaning tank takes place.

Desweiteren ist es möglich, daß die Ausdrückrolle 1 z. B. zwei oder mehrere Paare von entgegengesetzt orientierten Leitelementen 4 aufweist. Auch ist es möglich, daß die Walkelemente 4a, 4b nicht, wie hier gezeigt, jeweils die gleiche Länge besitzen und somit eine gleichförmige Axial-Teilung der Ausdrückrolle 1 ausbilden. Es ist auch möglich, daß die einzelnen Walkelemente 4a, 4b unterschiedlich lang gestaltet sind.Furthermore, it is possible that the Ausdrückrolle 1 z. B. has two or more pairs of oppositely oriented guide elements 4. It is also possible that the walk elements 4a, 4b, as shown here, each have the same length and thus form a uniform axial division of the squeeze roller 1. It is also possible that the individual Walk elements 4a, 4b are designed differently long.

Desweiteren ist es möglich, wenn auf die Ableitung der herausgewalkten Flüssigkeit in die Mitte des die Ausdrückrolle 1 aufnehmenden Reinigungsbehälters verzichtet werden soll, lediglich ein sich über den gesamten axialen Wirkbereich der Ausdrückrolle 1 erstreckendes Walkelement 4a vorzusehen.Furthermore, if it is desired to dispense with the discharge of the out-wiped liquid into the center of the squeezing roller 1 receiving cleaning container, it is only necessary to provide a wallowing element 4a extending over the entire axial effective range of the squeezing roller 1.

Die Ausbildung des Grundkörpers 2 als stangen- oder rohrförmiger Grundkörper 2 besitzt den Vorteil, daß ein derartiger Grundkörper 2 und somit eine derartige Ausdrückrolle 1 eine hohe axialer Stabilität, insbesondere gegen ein Durchbiegen aufweist. Auch eine derartige Ausbildung ist nicht zwingend erforderlich, wie anhand des erfindungsgemäßen Ausführungsbeispiels erläutert wird.The design of the base body 2 as a rod-shaped or tubular base body 2 has the advantage that such a base body 2 and thus such a squeeze roller 1 has a high axial stability, in particular against bending. Such a design is not absolutely necessary, as will be explained with reference to the embodiment of the invention.

In Figur 5 ist nun ein erfindungsgemäßes Ausführungsbeispiel einer Ausdrückrolle 1 dargestellt, wobei einander gleiche oder entsprechende Teile mit den gleichen Bezugsziffern versehen sind und nicht mehr näher beschrieben werden. Der wesentliche Unterschied zwischen den beiden Ausdrückrollen besteht nun darin, daß der Grundkörper 2 der Ausdrückrolle 1 nun nicht mehr stangen- oder rohrförmig ausgebildet ist, sondern durch eine gewisse Anzahl von Axialstegen 8a-8c, im hier gezeigten Ausführungsbeispiel von drei Axialstegen 8a-8c ausgebildet ist, auf denen die Walkelemente 4a, 4b aufgesetzt sind. Eine derartige Ausgestaltung besitzt den Vorteil, daß durch diese gitterartige Konstruktion der Ausdrückrolle 1 die aus dem Arbeitsbelag des zu reinigenden Werkzeugs herausgewalkte Flüssigkeit unmittelbar in den die beschriebene Ausdrückrolle 1 aufnehmenden Reinigungsbehälter abfließen kann.In FIG. 5 Now, an inventive embodiment of a squeeze roller 1 is shown, wherein the same or corresponding parts are provided with the same reference numerals and will not be described in detail. The essential difference between the two Ausdrückrollen is now that the main body 2 of the Ausdrückrolle 1 is no longer rod-shaped or tubular, but by a certain number of axial webs 8a-8c, formed in the embodiment shown here of three axial webs 8a-8c is on which the Walk elements 4a, 4b are placed. Such a configuration has the advantage that by this lattice-like construction of the squeezing roller 1, the liquid herausgewalkte from the working surface of the tool to be cleaned can flow directly into the described Ausdrückrolle 1 receiving cleaning container.

Ein weiterer Vorteil dieser gitterartigen Konstruktion der Ausdrückrolle 1 besteht darin, daß sie besonders einfach und materialsparend mittels eines Spritzgußverfahrens herstellbar ist.Another advantage of this grid-like construction of the Ausdrückrolle 1 is that it can be produced in a particularly simple and material-saving by means of an injection molding process.

Abschließend soll noch angeführt werden, daß die erfindungsgemäße Ausdrückrolle 1 anstelle der die Lagerachsen aufnehmenden Durchtrittsbohrung 3 an ihren dann vorzugsweise die Sperrelemente 10 ausbildenden Endflächen 1a und 1b jeweils eine Lagerachse 9 aufweist, über die sie am Reinigungsbehälter drehbar befestigbar ist.Finally, it should be stated that the Ausdrückrolle invention 1 instead of the bearing axes receiving through hole 3 at their then preferably the locking elements 10 forming end surfaces 1a and 1b each have a bearing axis 9, via which it is rotatably fastened to the cleaning container.

Es bedarf keiner weiteren Erläuterung, daß die gemachten Ausführungen zu der unterschiedlichen Anordnung und Konfiguration der Walkelemente 4a, 4b im Fall der zweiten Ausdrückrolle 1 entsprechend gelten.It requires no further explanation that the statements made to the different arrangement and configuration of the Walk elements 4a, 4b apply in the case of the second Ausdrückrolle 1 accordingly.

Zusammenfassend ist festzuhalten, daß durch die beschriebenen Maßnahmen eine Ausdrückrolle 1 geschaffen wird, welche sich dadurch auszeichnet, daß die aus der Arbeitsauflage des zu reinigen Werkzeugs herausgewalkte Flüssigkeit vollständig oder zum überwiegenden Teil in das Innere des die Ausdrückrolle 1 aufnehmenden Reinigungsbehälters geleitet wird, wodurch einer Entstehung von Lachen außerhalb des Reinigungsbehälters effizient entgegengewirkt wird. Die stegartige Ausgestaltung der Walkelemente 4a, 4b besitzt desweiteren den Vorteil, daß hierdurch ein verbessertes Herauswalken der in der Arbeitsauflage des zu reinigen Werkzeugs aufgenommene Flüssigkeit ermöglicht wird.In summary, it should be noted that a Ausdrückrolle 1 is created by the measures described, which is characterized in that the herausgewalkte from the working surface of the tool to be cleaned liquid is passed completely or predominantly into the interior of the Ausdrückrolle 1 receiving cleaning tank, creating a Formation of laughter outside the cleaning tank is efficiently counteracted. The web-like configuration of the Walk elements 4a, 4b further has the advantage that thereby an improved herauswalken the recorded in the work support of the tool to be cleaned liquid is made possible.
