Description

Die Erfindung betrifft eine in einer Fahrtrichtung verfahrbare Reinigungsvorrichtung für Textilmaschinen, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a movable in one direction Cleaning device for textile machines, according to the preamble of claim 1.

Derartige Textilmaschinen oder Wanderreiniger weisen Saugrohre oder -schläuche auf, die von der Reinigungsvorrichtung von oberhalb der Textilmaschinenreihe herunterhängen und für die Reinigung an bestimmten Stellen seitlich der Textilmaschine vorgesehen sind. Hierzu gehört auch der Bodenbereich seitlich der Textilmaschinenreihe, auf welchem sich Faserflug absetzt.Such textile machines or traveling cleaners have suction pipes or hoses from the cleaning device of hang down above the textile machine row and for the Cleaning at certain points on the side of the textile machine are provided. This also includes the floor area on the side the textile machine series on which fiber fly settles.

Es ist bekannt, die Saugrohre oder -schläuche beweglich zu lagern, so daß ein seitliches Ausweichen gegenüber Hindernissen möglich ist. Zu diesen Hindernissen gehören z.B. eine Fadenanknüpfmaschine, der die Reinigungsvorrichtung ausweichen muß.It is known to mount the suction pipes or hoses so that they can move, so that lateral avoidance against obstacles is possible. These obstacles include e.g. a thread tying machine, who must avoid the cleaning device.

So ist es aus der DE-GM 78 22 371 bekannt, einen flexiblen Schlauch beim Auftreffen auf ein Hindernis zu bewegen und durch die Bewegung einen Schutzschalter auszulösen, der die Fahrtrichtung der Reinigungsvorrichtung umkehrt. Eine weiter optimierte Betriebsweise einer derartigen Reinigungsvorrichtung ist aus dieser Druckschrift nicht bekannt.So it is known from DE-GM 78 22 371, a flexible Move hose when hitting an obstacle and by moving a circuit breaker, which the Reverses the direction of travel of the cleaning device. Another one optimized operation of such a cleaning device is not known from this publication.

Aus der gattungsgemäßen US-A-30 80 598 ist eine Textilmaschinen-Reinigungsvorrichtung bekannt, bei der ein unterer Klappabschnitt gelenkig an einem Rohr angebracht ist. Über Streifen soll ein Bodenkontakt gehalten werden. Wenn die Bodenunebenheiten zu groß sind, wird der Klappabschnitt abgehoben, so daß er nicht mehr ausreichend Saugleistung aufbringen kann.From the generic US-A-30 80 598 is a textile machine cleaning device known in which a lower folding section is articulated to a pipe. About stripes ground contact should be maintained. If the bumps are too large, the folding section is lifted off, so that he can no longer provide sufficient suction power.

Nachteilig bei der aus der DE-AS 18 83 152 bekannten Lösung mit einem flexibel gelagerten Saugmundstück ist, daß bei wirklich unebenen sowie bei stärker konturierten Böden eine echte Konturfolge nicht möglich ist. Vielmehr neigen die dortigen Füße dazu, sich bei echten Unebenheiten zu verhaken, was den Antrieb insgesamt bremst und zu gefährlichen Verkantungssituationen führen kann. Daher hat sich diese Lösung nicht durchgesetzt.A disadvantage of the solution known from DE-AS 18 83 152 with a flexibly mounted suction mouthpiece is that at really uneven as well as with more contoured floors a real one Contour sequence is not possible. Rather, those there tend to Feet to get caught in real bumps, which the Overall drive brakes and dangerous canting situations can lead. Therefore, this solution has not enforced.

Der Erfindung liegt daher die Aufgabe zugrunde, eine in einer Fahrtrichtung verfahrbare Reinigungsvorrichtung für Textilmaschinen gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die hinsichtlich der Konturfolgefähigkeit deutlich verbessert ist und deren Betriebsweise, insbesondere deren Saugwirkungsgrad insgesamt betrachtet erheblich erhöht ist.The invention is therefore based on the object, one in one Moving cleaning device for textile machines according to the preamble of claim 1 to create the is significantly improved in terms of contour following and their mode of operation, especially their suction efficiency viewed overall, is significantly increased.

Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by claim 1. Advantageous further developments result from the subclaims.

Erfindungsgemäß ist zur Konturfolge vorgesehen, daß das Saugrohr unten einen Klappabschnitt aufweist, der beim Auftreffen auf eine entsprechende Kontur kurzerhand nach hinten, also horizontal wegzuklappen in der Lage ist. Besonders günstig ist es hierbei, daß gleichermaßen automatisch eine Düsenöffnung des Saugrohrs freigegeben wird, die wiederum der intensiven Besaugung der auf der Kontur bestehenden Oberfläche dienen kann. Eine Anwendung ist beispielsweise eine Webmaschinenreihe mit Webergängen, die bislang nur in sehr unbefriedigender Weise, insbesondere manuell, gereinigt werden konnten. Nunmehr ist es möglich, sowohl den Boden seitlich neben der Webmaschine als auch den aus einem Brett bestehenden Webergang optimal abzusaugen und den sich dort absetzenden Faserflug aufzufangen.According to the invention, for the contour sequence, it is provided that the intake manifold has a folding section at the bottom, which when striking to a corresponding contour without further ado, i.e. horizontally is able to fold away. Is particularly cheap it here that equally automatically opens a nozzle the intake manifold is released, which in turn is the intense Vacuum the surface existing on the contour can. One application is, for example, a weaving machine series with weavers that have so far been very unsatisfactory, especially manually. Now it is possible to have both the bottom to the side of the weaving machine as well as the one-board weaving course suck off and catch the fiber fly settling there.

Besonders günstig läßt sich die Erfindung mit einem Saugrohr oder einem Saugschlauch einsetzen. Nachstehend wird für derartige Rohre oder Schläuche grundsätzlich der Begriff Saugrohr verwendet, auch wenn eine gewisse Flexibilität vorhanden ist. Es versteht sich, daß im Grunde die Erfindung auch in Verbindung mit einem Blasrohr oder -schlauch einsetzbar ist, auch wenn der besonders günstige Effekt des automatischen Ansaugens des Klappabschnitts in der unteren Position des Klappabschnitts, in welcher der Fußboden gereinigt wird, bei Verwendung eines Blasrohres oder -schlauches entfällt.The invention can be particularly inexpensive with a suction pipe or use a suction hose. The following is for such Pipes or hoses basically the term suction pipe used, even if there is some flexibility. It is understood that basically the invention is also in connection can be used with a blowpipe or hose, too if the particularly beneficial effect of automatic suction the folding section in the lower position of the folding section, in which the floor is cleaned when in use a blowpipe or hose is not required.

Besonders günstig ist es, daß der erfindungsgemäße besonders günstige Effekt mit sehr einfachen Mitteln realisierbar ist: sobald der Klappabschnitt auf die Kontur trifft, wird er nach hinten weggeklappt und erstreckt sich dann im wesentlichen horizontal. Bei Bewegung der Reinigungsvorrichtung in Fahrtrichtung schleift er mit seiner unteren/vorderen Fläche über die Oberfläche der Kontur und gibt in der bevorzugten Ausgestaltung die Saugöffnung des Saugrohrs frei. Die verfügbare Saugleistung steht so stets an der optimalen Stelle, d.h., knapp oberhalb der zu reinigenden Oberfläche, zur Verfügung, entweder also auf der Oberfläche der Kontur oder auf der Oberfläche des Fußbodens. Auch in der Fußbodenreinigungsstellung tritt keine Nebenluft an dem Gelenk zwischen Saugrohr und Klappabschnitt ein, nachdem dann eine umlaufend vorgesehene Dichtung wirksam wird, die beim Ansaugen des Klappabschnitts über das Saugrohr eine Abdichtung zwischen diesen Teilen bewirkt.It is particularly favorable that the invention is particularly favorable effect can be achieved with very simple means: as soon as the folding section meets the contour, it will follow folded away at the back and then extends essentially horizontally. When moving the cleaning device in the direction of travel he grinds with his lower / front surface over the Surface of the contour and gives in the preferred embodiment the suction opening of the suction pipe is free. The available suction power is always in the optimal position, i.e., scarce above the surface to be cleaned, either that is on the surface of the contour or on the surface of the floor. Also occurs in the floor cleaning position no secondary air at the joint between the intake manifold and the folding section one, then a circumferential seal is effective, which when sucking the folding section on the Intake pipe creates a seal between these parts.

Zweckmäßig ist ein Gelenk am rückwärtigen Ende des Saugrohrs an einer Stelle von der Saugöffnung beabstandet angeordnet, welcher Abstand in etwa den Durchmesser des Saugrohrs bzw. des Klappabschnitts entspricht. Bei dieser Stellung ist es besonders günstig, daß der Klappabschnitt aufgrund der bestehenden Hebelverhältnisse beim Auftreffen auf die Kontur leicht wegklappbar ist und daß dennoch die Saugöffnung sich knapp oberhalb der Konturoberfläche erstrecken kann.A joint at the rear end of the suction pipe is expedient arranged at a point at a distance from the suction opening, which distance roughly the diameter of the suction pipe or Folding section corresponds. It is special in this position favorable that the folding section due to the existing Lever ratios easily collapsible when hitting the contour and that the suction opening is still just above the contour surface can extend.

Besonders günstig ist es ferner, daß in der Fußbodensaugstellung aufgrund des herrschenden Unterdrucks der Klappabschnitt praktisch gegen die Saugrohrdichtung gezogen wird. Auch bei abrupten Maschinenbewegungen kann so keine Fehlluft an dieser Stelle eintreten. Beim Betätigen der Steuerfläche des Klappabschnitts wird andererseits nach Überwindung eines Widerstands der Klappabschnitt schlagartig freigegeben und kann so in die erwünschte Position oberhalb einer Kontur überführt werden.It is also particularly favorable that in the floor suction position due to the prevailing negative pressure of the folding section is practically pulled against the intake manifold seal. Also at abrupt machine movements so there is no bad air on this Job. When pressing the control surface of the folding section on the other hand, after overcoming resistance the folding section suddenly released and can thus in the desired position can be transferred above a contour.

Weitere Vorteile, Einzelheiten und Merkmale ergeben sich aus der nachstehenden Beschreibung zweier Ausführungsbeispiele der Erfindung anhand der Zeichnung.Further advantages, details and features result from the following description of two embodiments of the Invention based on the drawing.

Eine Reinigungsvorrichtung 10 weist ein Saugrohr 12 auf, von dem nur das untere Ende dargestellt ist. Das Saugrohr 12 endet in einem erfindungsgemäßen Klappabschnitt 14, der sich in der in Fig. 1 dargestellten Fußbodensaugstellung unterhalb des Saugrohrs 12 in dessen Verlängerung erstreckt. In der Darstellung gemäß Fig. 1 ist der Klappabschnitt 14 über ein Elastomerband 16 mit dem Saugrohr 12 verbunden. Das Elastomerband 16 ist so vorgespannt, daß der Klappabschnitt 14 in die in Fig. 1 dargestellte Stellung gedrückt wird. Ohne Saugluft im Saugrohr 12 hängt der Klappabschnitt 14 jedoch leicht gekippt; durch den Saugunterdruck im Saugrohr 12 wird er in die in Fig. 1 dargestellte Stellung gezogen. Das Elastomerband 16 ist über einen Flansch 18 oben an dem Saugrohr 12 befestigt, wobei der Abstand zwischen dem Flansch 18 und dem unteren Ende des Saugrohrs 12 etwas mehr als der Durchmesser des Saugrohrs 12 und des Klappabschnitts 14 ist. Das Elastomerband 16 ist über einen weiteren Flansch 20 an dem Klappabschnitt 14 befestigt, und zwar im wesentlichen bündig mit dessen Oberkante. In dieser Ausgestaltung dient das Elastomerband 16 als Gelenk zwischen Saugrohr 12 und Klappabschnitt 14.A cleaning device 10 has a suction pipe 12 from which only shows the lower end. The suction pipe 12 ends in a folding section 14 according to the invention, which is in the Floor suction position shown in Fig. 1 below the Suction pipe 12 extends in its extension. In the illustration 1, the folding section 14 is via an elastomeric band 16 connected to the suction pipe 12. The elastomeric tape 16 is biased so that the folding portion 14 in the in Fig. 1st position shown is pressed. Without suction air in the suction pipe 12, however, the folding section 14 hangs slightly tilted; by the suction vacuum in the intake manifold 12 is shown in FIG. 1 position shown drawn. The elastomeric band 16 is over a flange 18 attached to the top of the suction pipe 12, the Distance between the flange 18 and the lower end of the intake manifold 12 slightly more than the diameter of the intake manifold 12 and of the folding section 14. The elastomeric band 16 is over one another flange 20 attached to the folding section 14, essentially flush with the top edge. In this Design serves the elastomeric band 16 as a joint between Intake pipe 12 and folding section 14.

Das Saugrohr 12 tritt leicht in den Klappabschnitt 14 ein, beispielsweise 1 - 2 mm. Es stützt sich dort auf einem Stützring 22 ab, der umläuft und auf dem eine Ringdichtung aufgelegt ist, die verhindert, daß Luft zwischen Saugrohr 12 und Klappabschnitt 14 eingesaugt werden kann. Die Eindringtiefe des Saugrohrs 12 ist so, daß eine Kippbewegung zwischen dem Klappabschnitt 14 und dem Saugrohr 12 nicht behindert wird.The suction pipe 12 easily enters the folding section 14, for example 1-2 mm. It is supported there on a support ring 22 from which rotates and on which a ring seal is placed is that prevents air between the suction pipe 12 and Folding section 14 can be sucked. The depth of penetration of the suction tube 12 is such that a tilting movement between the Folding section 14 and the suction pipe 12 is not hindered.

Die Reinigungsvorrichtung 10 bewegt sich in der in Fig. 1 mit einem Pfeil 24 dargestellten Fahrtrichtung. Am oberen/vorderen Ende des Klappabschnitts 14 ist eine Steuerfläche 26 ausgebildet, die der Einleitung der Kippbewegung des Klappabschnitts 14 dient. Die Steuerfläche 26 ist vorgewölbt und kann beispielsweise durch eine in das obere Ende des Klappabschnitts 14 eingehängte Lasche realisiert sein. Sie bildet eine gleitfähige Führungsfläche, die für die Anlage an einer Kontur 28 ausgelegt ist. Sobald sie an einer Vorderkante 30 der Kontur anstößt, wird die Bewegung des Wegklappens des Klappabschnitts 14 eingeleitet. Die hintere Kante des Klappabschnitts 14 stützt sich über den Stützring 22 zunächst noch an dem unteren Ende des Saugrohrs 12 ab, so daß dieses als Lagerpunkt dient. Der Abstand zwischen der Kontur 28 und dem unteren Ende des Saugrohrs 12 beträgt etwa ein Drittel des Saugrohrdurchmessers, so daß die Hebelverhältnisse ohne weiteres ein Wegklappen nach hinten erlauben. Sobald sich die obere Kante des Klappabschnitts 14 vorne von der unteren Kante des Saugrohrs 12 getrennt hat, gleitet der Klappabschnitt insgesamt nach hinten, wobei das Elastomerband 16 ausgelenkt wird. In diesem Falle wirkt ein Punkt etwas unterhalb des Flansches 18 als Drehpunkt, so daß die Vorderkante 30 der Kontur 28 an der Steuerfläche 26 entlanggleitet. Hierdurch wird der Klappabschnitt 14 nach oben gehebelt, bis er in die in Fig. 2 dargestellte, liegende oder Kontursaugstellung gerät. In dieser Stellung schleppt das Elastomerband 16 den Klappabschnitt 14 praktisch nach.The cleaning device 10 moves in the in Fig. 1 an arrow 24 direction of travel. On the top / front A control surface 26 is formed at the end of the folding section 14, the initiation of the tilting movement of the folding section 14 serves. The control surface 26 is arched and can for example through one in the top end of the folding section 14 hooked tab can be realized. It forms a lubricious Guide surface that is designed for contact with a contour 28 is designed. Once at a leading edge 30 of the contour abuts, the movement of folding away the folding section 14 initiated. The rear edge of the folding section 14 is initially supported by the support ring 22 on the lower one End of the suction pipe 12, so that this serves as a bearing point. The distance between the contour 28 and the lower end of the Intake manifold 12 is approximately one third of the intake manifold diameter, so that the lever ratios easily fold away allow to the rear. Once the top edge of the Folding section 14 front of the lower edge of the intake manifold 12 has separated, the folding section slides overall rear, the elastomeric band 16 being deflected. In this Trap acts as a point slightly below the flange 18 Pivot point, so that the front edge 30 of the contour 28 on the Control surface 26 slides along. This will make the folding section 14 levered upwards until it is shown in FIG. horizontal or contour suction device. In this Position, the elastomeric tape 16 drags the folding section 14 practically after.

In Fig. 2 wie auch in den weiteren Figuren dienen gleiche Bezugszeichen zur Markierung gleicher oder entsprechender Teile. Der Klappabschnitt 14 ist an seinem unteren Ende mit einem Gleitnoppen 32 versehen, der das Gleiten auf einer Oberfläche 34 der Kontur erleichtert. Der Gleitnoppen 32 wie auch die Steuerfläche 26 sind mit besonderem Gleitmittel, wie beispielsweise Teflon, versehen, so daß nach dem Wegklappen des Klappabschnitts 14 keine besonderen Schleppwiderstände zu bemerken sind. Dies kommt nicht nur der Lebensdauer der vorgestellten Lösung, sondern auch der Antriebsleistung der Reinigungsvorrichtung bzw. deren Wirkungsgrad zugute.The same reference numerals are used in FIG. 2 and in the other figures for marking identical or corresponding parts. The folding section 14 is at its lower end with a Sliding knobs 32 provided that the sliding on a surface 34 the contour relieved. The sliding knobs 32 as well Control surface 26 are with special lubricant, such as Teflon, provided so that after folding away the Folding section 14 to notice no special drag resistances are. This comes not only from the lifespan of the featured Solution, but also the drive power of the cleaning device or their efficiency benefits.

Wie aus Fig. 1 im Vergleich mit Fig. 2 ersichtlich ist, ist der Saugabstand zwischen einem Fußboden 36 und dem unteren Ende des Klappabschnitts 14 einerseits bzw. der Oberfläche 34 der Kontur 28 und einer Saugöffnung 38 des Saugrohrs 12 andererseits etwa gleich und beträgt etwa ein Drittel Saugrohrdurchmessers. Es versteht sich, daß dieser Abstand bei Bedarf entsprechend angepaßt werden kann. As can be seen from FIG. 1 in comparison with FIG. 2, is the suction distance between a floor 36 and the lower end of the folding section 14 on the one hand or the surface 34 the contour 28 and a suction opening 38 of the suction pipe 12 on the other hand about the same and is about a third of the intake manifold diameter. It is understood that this distance if necessary can be adjusted accordingly.

Sobald das hintere Ende der Kontur 28 erreicht ist, wird die Rückbewegung des Klappabschnitts 14 eingeleitet. Die Steuerfläche 26 gleitet zunächst über die nicht dargestellte Hinterkante der Kontur 28. Aufgrund der Vorspannung des Elastomerbands 16 in Richtung der in Fig. 1 dargestellten Stellung wird dann der Klappabschnitt 14 beim Absenken seines vorderen Teils zum Saugrohr 12 herangezogen und befindet sich erheblich näher als in Fig. 2 dargestellt an dem Saugrohr 12, sobald das vollständige Kippen erfolgt, sobald also der Gleitnoppen 32 die Hinterkante der Kontur 28 verlassen hat.As soon as the rear end of the contour 28 is reached, the Return movement of the folding section 14 initiated. The control surface 26 initially slides over the trailing edge, not shown the contour 28. Due to the prestressing of the elastomer tape 16 in the direction of the position shown in Fig. 1 then the folding section 14 when lowering its front part pulled to the intake manifold 12 and is considerably closer as shown in Fig. 2 on the intake manifold 12 once the complete Tilting takes place as soon as the sliding knobs 32 Has left the rear edge of the contour 28.

Die in Fig. 3 und 4 dargestellte Ausführungsform der erfindungsgemäßen Reinigungsvorrichtung 10 erlaubt ein Wegklappen des Klappabschnitts 14 um nahezu 180°. In diesem Ausführungsbeispiel ist die Kontur 28 als feste Stufe ausgebildet, während sie in Fig. 1 und 2 als Brett vorgesehen war. Ein Beispiel für eine derartige Kontur ist der Webergang neben einer Webmaschine.The embodiment of the invention shown in FIGS. 3 and 4 Cleaning device 10 allows folding away of the folding section 14 by almost 180 °. In this embodiment the contour 28 is formed as a fixed step while it was provided in Fig. 1 and 2 as a board. An example for such a contour, the weaving aisle is next to one Weaving machine.

Auch in der Ausgestaltung gemäß Fig. 3 und 4 ist eine Steuerfläche 26 vorgesehen, die mit der Vorderkante 30 der Kontur zusammenwirkt und die Kippbewegung einleitet. Im Unterschied zu der bislang dargestellten Ausführungsform ist ein Gelenk 40 am rückwärtigen Ende von Saugrohr 12 und Klappabschnitt 14 - bezogen auf die Fahrtrichtung 24 - vorgesehen, wobei der Drehpunkt des Gelenks 40 knapp oberhalb des unteren Endes des Saugrohrs 12 ist. Das Gelenk 40 ist an sich bekannter Weise durch zwei je angeschweißte Flansche 42 und 44 gebildet, die die Verbindung zwischen dem Saugrohr 12 und dem Klappabschnitt 14 sicherstellen.3 and 4 is also a control surface 26 provided with the front edge 30 of the contour cooperates and initiates the tilting movement. The difference to the embodiment shown so far is a joint 40 at the rear end of intake manifold 12 and folding section 14 - Based on the direction of travel 24 - provided, the Pivot of the joint 40 just above the lower end of the Suction pipe 12 is. The hinge 40 is known per se formed by two welded flanges 42 and 44, respectively the connection between the suction pipe 12 and the folding section 14 ensure.

In diesem Ausführungsbeispiel endet das untere Ende des Saugrohrs 12 lediglich knapp oberhalb der Oberfläche 34 der Kontur 28, so daß eine intensive Feinsaugung dieser Oberfläche möglich ist. Die Steuerfläche 26 weist eine solche Wölbung auf, daß der Erstanlagepunkt 46, also der Punkt, an welchem die Steuerfläche 26 zunächst mit der Vorderkante 30 der Kontur 28 in Kontakt gerät, beträchtlich unterhalb des unteren Endes des Saugrohrs 12 ist. Wie aus Fig. 3 ersichtlich ist, sollte der Abstand D zwischen dem Erstanlagepunkt 46 und dem Gelenk 40 in der Höhe nicht zu gering sein, damit die Kippbewegung ohne größere Scherkräfte eingeleitet werden kann. Beim Kippen gleitet die Vorderkante 30 an der Steuerfläche 26 entlang, wobei die Steuerfläche 26 - wie aus Fig. 4 ersichtlich ist - um den oberen Rand des Klappabschnitts 14 herumgezogen ist und wobei der Klappabschnitt 14 in der aus Fig. 4 ersichtlichen weggeklappten Stellung kopfüber mit der Steuerfläche 26 auf der Oberfläche 34 der Kontur 28 gleitet.In this embodiment, the lower end of the suction pipe ends 12 only just above the surface 34 of the contour 28, so that an intensive fine suction of this surface is possible is. The control surface 26 has such a curvature that the initial investment point 46, that is the point at which the Control surface 26 first with the front edge 30 of the contour 28 comes into contact, considerably below the lower end of the Suction pipe 12 is. As can be seen from Fig. 3, the Distance D between the initial contact point 46 and the joint 40 in the height should not be too low so that the tilting movement without greater shear forces can be introduced. Slides when tilted the leading edge 30 along the control surface 26, wherein the control surface 26 - as can be seen from Fig. 4 - around the the upper edge of the folding portion 14 is pulled around and the folding section 14 in the one shown in FIG. 4 folded away Position upside down with the control surface 26 on the Surface 34 of the contour 28 slides.

Wie aus Fig. 3 ebenfalls ersichtlich ist, ist die untere Öffnung des Klappabschnitts 14 ganz knapp oberhalb des Fußbodens 36, so daß auch hier eine Feinsaugung erfolgt. Es versteht sich, daß die Steuerfläche 26 ebenfalls gleitfähig ausgestattet ist, wobei sie auch an dem in Fig. 3 oberen Rand abgeflacht und gerundet ist, um so einen geringen Widerstand für etwaige Unebenheiten der Oberfläche 34 zu bieten.As can also be seen from Fig. 3, is the lower opening of the folding section 14 just above the floor 36, so that fine suction also takes place here. It understands yourself that the control surface 26 is also slidably equipped is, it also being flattened at the upper edge in FIG. 3 and rounded, so there is little resistance for to offer any unevenness of the surface 34.

Wie aus Fig. 4 ersichtlich ist, erstreckt sich der Klappabschnitt 14 auch in der weggeklappten Stellung nicht exakt senkrecht nach oben, sondern nur etwa im Winkel von 170° bezogen auf die in Fig. 3 dargestellte Stellung. Hierdurch besteht eine gewisse Kippreserve bei Unebenheiten der Oberfläche 34. Außerdem ist eine Klappung um 180° gar nicht nötig, da ein gewisser minimaler Saugabstand für das Eintreten der Saugluft an der Saugöffnung 38 erforderlich ist.As can be seen from Fig. 4, the folding section extends 14 not exactly in the folded position vertically upwards, but related only at an angle of 170 ° to the position shown in Fig. 3. As a result a certain tilt reserve if the surface is uneven 34. In addition, a folding by 180 ° is not necessary at all, since one certain minimum suction distance for the entry of the suction air at the suction opening 38 is required.

Es versteht sich, daß das Gelenk 40 entsprechend dem Elastomerband 16 aus Fig. 1 federbelastet ist, so daß der Klappabschnitt 14 frei hängend die in Fig. 3 dargestellte Position einnimmt. Es ist auch möglich, die Federbelastung so gering zu wählen, daß der Klappabschnitt 14 nur etwas in Richtung auf das Saugrohr 12 gedrückt wird. Durch den Unterdruck im Saugrohr 12 erfolgt dann ein vollständiges Ansaugen.It is understood that the hinge 40 corresponds to the elastomeric band 16 from Fig. 1 is spring-loaded, so that the folding section 14 hanging freely the position shown in Fig. 3 occupies. It is also possible to reduce the spring load as little choose that the folding section 14 only slightly towards the suction pipe 12 is pressed. Due to the negative pressure in the intake manifold 12 then complete suction takes place.

Bei Bedarf kann die Gelenkachse 40 auch weiter nach links, also etwa bis zur Mitte des Rohres, verlagert werden. In diesem Falle ist die Federbelastung entbehrlich.If necessary, the articulation axis 40 can also continue to the left, that is about to the middle of the pipe. In this The spring loading is not necessary.

Die aus den Fig. 5 und 6 ersichtliche Ausgestaltung macht eine Federbelastung des Gelenks entbehrlich. Hier ist das Gelenk 40 mittig angeordnet, so daß der Klappabschnitt 14 symmetrisch nach beiden Richtungen verschwenkbar ist. Dies ist insbesondere dann von Bedeutung, wenn die Fahrtrichtung der Reinigungsvorrichtung umkehrbar ist.The embodiment shown in FIGS. 5 and 6 makes one There is no need for a spring load on the joint. Here is joint 40 arranged in the center, so that the folding section 14 is symmetrical is pivotable in both directions. This is particularly so important if the direction of travel of the cleaning device is reversible.

Der Schwenkpunkt des Klappabschnitts 14, also das Gelenk 40, ist mindestens um den Radius des Saugrohrs 12 von der Unterkante des Saugrohres an der Saugöffnung 38 beabstandet. Hierdurch läßt sich der Klappabschnitt 14 frei verschwenken.The pivot point of the folding section 14, that is to say the joint 40, is at least around the radius of the suction pipe 12 from the lower edge of the suction pipe at the suction opening 38. Hereby the folding section 14 can pivot freely.

In dem dargestellten Ausführungsbeispiel gibt der Klappabschnitt 14 seitlich einen Schlitz 48 frei, wenn er sich in der im wesentlichen horizontalen Stellung befindet. Über diesen Schlitz wird zusätzlich Luft von der Seite angesaugt, was in dem dargestellten Ausführungsbeispiel gewünscht ist. Es versteht sich, daß der Schlitz gewünschtenfalls auch von einer Schürze abgedeckt sein kann oder das Saugrohr 12 vollständig nach unten gezogen sein kann, wenn keine zusätzliche seitliche Ansaugung gewünscht ist.In the illustrated embodiment, the folding section 14 laterally a slot 48 free when it is in the is located substantially in the horizontal position. About this Slot is additionally sucked in air from the side, which in the illustrated embodiment is desired. It understands that the slot can also be of a Apron can be covered or the suction pipe 12 completely can be pulled down if no additional side Suction is desired.

In dem Ausführungsbeispiel der Fig. 5 und 6 ist der Klappabschnitt 14 mit einem Verstärkungsring 50 versehen, der eine Verformung des Klappabschnitts 14 beim Anschlagen an ein Hindernis verhindert. Ferner ist eine Manschette 52 vorgesehen, die ebenfalls der Aussteifung des Klappabschnitts 14 dient.5 and 6 is the folding section 14 provided with a reinforcing ring 50, the one Deformation of the folding section 14 when striking an obstacle prevented. A sleeve 52 is also provided, which also serves to stiffen the folding section 14.

Gemäß einer weiteren Ausgestaltung, die für eine stärker strukturierte Kontur mit einer weiteren Stufe vorgesehen ist, erstreckt sich unterhalb des Klappabschnitts 14 ein weiterer Klappabschnitt mit einem dem Gelenk 40 entsprechenden Gelenk.According to another embodiment, which is for a stronger structured contour with a further level is provided, another extends below the folding section 14 Folding section with a joint corresponding to joint 40.
