Definitions
- the present invention relates to a picking sweeper with a dirt collecting container to which on the one hand a suction fan and on the other hand connected via a suction line a suction head with a suction shaft and a working surface in front of this extending flexible planar flow guide.
- the present invention relates to a picking sweeper according to the preamble of claims 1 and 3.
- Picking sweepers are known in various designs and configurations of the prior art. Namely, self-propelled picking sweepers and pickup sweeping machines pulled by a towing vehicle are known for cleaning traffic areas such as, in particular, roads and sidewalks, squares, runways and the associated apron and the like.
- Suction heads of this type are known, for example from the DE 2918760 A1 , which discloses a generic receiving sweeper, and the GB 1046341 , of the GB 1530904 as well as the AU 462011 ,
- suction heads with (front) Grobgutklappen are also known, which can be mechanically opened and closed again.
- Such coarse material flaps can in particular be rigid, pivotable and / or liftable components (cf., eg, FIG DE 3437990 A1 ) as well as deformable, consisting of a flexible material components (see. ES 2369983 A1 ).
- they do not constitute a planar flow guide element extending in the working direction in front of the suction shaft, in the sense that a fluidically optimized nozzle effect is achieved between it and the surface to be cleaned.
- a double suction is known in which the first, in the working direction front suction mouth is connected via a suction line with a nozzle which is directed in the working direction immediately before the second suction mouth against the surface to be cleaned.
- the nozzle is sealed from the second suction mouth by means of a rolling diaphragm which functions as a coarse slide and increases the gap width for the suction flow when the nozzle is raised.
- the present invention seeks to provide a picking sweeper of the type described, which is characterized with a comparatively low power consumption of the suction fan with high reliability by a typical application conditions very good cleaning result.
- "typical" operating conditions include those in which significant amounts of relatively bulky debris are to be included, such as more or less accumulated leaves in autumn.
- the edge of the flow guide element facing away from the suction channel is at least substantially linearly displaceable by means of the adjustment device
- the realization of the adjustment device is made possible for example by a hydraulic cylinder (or several hydraulic cylinders), without additional facial expressions such as a deflection gear or the like.
- edge of the flow guide element facing away from the suction shaft is substantially parallel to the surface to be cleaned or slidably displaced comparatively small, allows the execution of the suction head - despite an adjustability of the gap width within a wide range - with a comparatively small height of the suction head, which is favorable for the possibility to lift the suction head in a transport position so far from the surface to be cleaned, that no risk of Damage to the suction head in the raised transport position due to obstacles.
- a comparatively short embodiment of the suction head in the working direction can be realized, in particular, when the planar flow guide element is guided away from the suction shaft via a deflection roller. Because in this case does not need to be held at the front of the suction head space for the stretched geometry of the flow guide, which does not need it in the strongly curved geometry of the flow. However, such a deflection of the flow-guiding element is typically accompanied by an increased overall height of the suction head, which may prove less favorable in individual cases. And the planar flow guide is - by comparatively low inherent rigidity - adapt to the deflection.

- the advantage of the comparatively small dimensions of the suction head in the working direction also applies to this development.
- the position of the edge of the flow-guiding element adjacent to the suction duct is preferably relative fixed to the suction shaft. With regard to a fluidic and energetic optimization, the position is particularly preferably chosen such that the flow guide element directly adjoins the suction shaft. Ideally, the edge region of the flow guide element immediately adjacent to the suction chute is fixed and geometrically fixed in such a way that a continuous transition from the flow guide element to the suction chute is ensured, regardless of the set gap width.
- the flow guide can be designed in particular as an elastically deformable flow baffle.

- Such a design of the flow guide proves to be advantageous in particular when it is deflected over a guide roller or wound onto a winding roller (see above).
- the respective geometry of the flow-guiding element can thereby be free, ie set according to a chain line, if the flow-guiding element "sags" at least in regions freely downwards in the direction of the surface to be cleaned.
- the latter is by no means compulsory.
- a kind of tension roller - or a plurality of tension rollers comprehensive tension roller unit - may be provided which defines the apex of the flow, wherein such a tension roller may be biased in particular spring loaded.

Description
Die vorliegende Erfindung betrifft eine aufnehmende Kehrmaschine mit einem Schmutzsammelbehälter, an welchem einerseits ein Sauggebläse und andererseits über eine Saugleitung ein Saugkopf mit einem Saugschacht und einem sich in Arbeitsrichtung vor diesem erstreckenden flexiblen flächigen Strömungsleitelement angeschlossen sind. Insbesondere betrifft die vorliegende Erfindung eine aufnehmende Kehrmaschine gemäß dem Oberbegriff der Ansprüche 1 und 3. Aufnehmende Kehrmaschinen zählen in diversen Ausführungen und Ausgestaltungen zum Stand der Technik. Namentlich sind bekannt selbstfahrende aufnehmende Kehrmaschinen sowie von einem Zugfahrzeug gezogene aufnehmende Kehrmaschinen zum Reinigen von Verkehrsflächen wie insbesondere Straßen und Gehwegen, Plätzen, Start- und Landebahnen sowie dem zugehörigen Vorfeld und dergleichen.The present invention relates to a picking sweeper with a dirt collecting container to which on the one hand a suction fan and on the other hand connected via a suction line a suction head with a suction shaft and a working surface in front of this extending flexible planar flow guide. In particular, the present invention relates to a picking sweeper according to the preamble of
Zwei besonders wichtige praxisrelevante Aspekte bei derartigen aufnehmenden Kehrmaschinen sind einerseits die Qualität des Reinigungsergebnisses und andererseits die hierfür aufzuwendende Energie. Typischerweise geht ein gutes Reinigungsergebnis mit einem hohen Energieverbrauch für den Betrieb des Sauggebläses einher. Um den Energieverbrauch zu begrenzen dienen strömungstechnisch optimierte Saugköpfe, bei denen durch ein flächiges Strömungsleitelement - zwischen diesem und der zu reinigenden Oberfläche - ein düsenförmiger Luftströmungsweg definiert wird, welcher typischerweise in Strömungsrichtung betrachtet einen ersten Bereich mit sich reduzierender und einen zweiten Bereich mit sich vergrößernder Spalthöhe zur zu reinigenden Oberfläche umfasst, wobei typischerweise die Erstreckung der beiden Bereiche in Arbeitsrichtung des Saugkopfes etwa in ähnlicher Größenordnung liegt. Ein weiterer praxisrelevanter Aspekt betrifft die Ausführung des Saugkopfes im Hinblick auf die Möglichkeit, Kehrgut unterschiedlichster Art und Gestalt (groß, klein, leicht, schwer) von der zu reinigenden Oberfläche aufzunehmen. Auch hier besteht ein Zielkonflikt insoweit, als die Möglichkeit, Grobgut aufzunehmen, in der Regel mit einer entsprechend großen frontseitigen Spaltweite am Saugkopf einhergeht, was wiederum, um gute Reinigungsergebnisse zu erzielen, einen Betrieb des Sauggebläses mit hoher Leistung voraussetzt. Dies ist nicht nur unter energetischen Gesichtspunkten unerwünscht; vielmehr ist bei solchen Kehrmaschinen auch die vergleichsweise hohe Lärmemission (sowohl zuströmseitig als auch abströmseitig) nachteilig.Two particularly important practical aspects of such picking sweepers are, on the one hand, the quality of the cleaning result and, on the other hand, the energy required for this purpose. Typically, a good cleaning result is accompanied by a high energy consumption for the operation of the suction fan. In order to limit the energy consumption serve suction cups optimized in terms of flow, in which a nozzle-shaped air flow path is defined by a planar flow guide element - between this and the surface to be cleaned typically viewed in the flow direction comprises a first region with a reducing and a second region with increasing gap height to the surface to be cleaned, typically the extent of the two regions in the working direction of the suction head is approximately of a similar magnitude. Another practical aspect concerns the design of the suction head with regard to the possibility of picking up debris of various types and shapes (large, small, light, heavy) from the surface to be cleaned. Again, there is a conflict of objectives insofar as the possibility to take coarse, usually accompanied by a correspondingly large front gap on the suction head, which in turn, in order to achieve good cleaning results, requires operation of the suction fan with high performance. This is not only undesirable from an energetic point of view; rather, the comparatively high noise emission (both upstream and downstream) is disadvantageous in such sweepers.
Vor diesem Hintergrund existieren verschiedene Ansätze, das sich in Arbeitsrichtung vor dem Saugschacht erstreckende flächige Strömungsleitelement, an welchem die angesaugte Luft entlang strömt, flexibel auszuführen dergestalt, dass im "normalen" Kehrbetrieb zwischen dem Strömungsleitelement und der zu reinigenden Oberfläche ein vergleichsweise geringer Spalt besteht, so dass dort auch bei vergleichsweise geringen Leistungsaufnahmen des Sauggebläses ausreichend hohe Strömungsgeschwindigkeiten vorliegen, wobei sich das Strömungsleitelement verformt, wenn es auf Grobgut (z.B. eine Dose) auftrifft. Saugköpfe dieser Art sind beispielsweise bekannt aus der
Um zwischen zwei Betriebsweisen, nämlich der Aufnahme von Normalgut einerseits und der Aufnahme von Grobgut andererseits umschalten zu können, sind darüber hinaus auch Saugköpfe mit (frontseitigen) Grobgutklappen bekannt, welche mechanisch geöffnet und wieder verschlossen werden können. Solche Grobgutklappen können dabei insbesondere als in sich starre, verschwenkbare und/oder anhebbare Bauteile (vgl. z.B.
Statt die Grobgutklappe in Arbeitsrichtung nach vorne schwenkbar auszuführen kann jene Klappe auch entgegen der Arbeitsrichtung nach hinten verschwenkbar sein, wobei der Abstand zwischen der Grobgutklappe und dem Saugschacht mittels einer elastischen Schürze überbrückt ist, welche eingefaltet wird, wenn die Grobgutklappe zur Aufnahme von Grobgut nach hinten verschwenkt wird (vgl.
Schließlich ist aus der
Vor dem Hintergrund des vorstehend dargelegten Standes der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine aufnehmende Kehrmaschine der eingangs angegebenen Art bereitzustellen, die sich bei einer vergleichsweise geringen Leistungsaufnahme des Sauggebläses bei hoher Betriebssicherheit durch ein bei typischen Anwendungsbedingungen sehr gutes Reinigungsergebnis auszeichnet. In diesem Sinne sind unter "typischen" Betriebsbedingungen auch solche zu verstehen, bei denen erhebliche Mengen von vergleichsweise voluminösem Kehrgut aufzunehmen sind, wie beispielsweise mehr oder weniger angehäuftes Laub im Herbst.Against the background of the above-described prior art, the present invention seeks to provide a picking sweeper of the type described, which is characterized with a comparatively low power consumption of the suction fan with high reliability by a typical application conditions very good cleaning result. In this sense, "typical" operating conditions include those in which significant amounts of relatively bulky debris are to be included, such as more or less accumulated leaves in autumn.
Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung durch die in Anspruch 1 oder in Anspruch 3 angegebene aufnehmende Kehrmaschine. Demgemäß zeichnet sich die erfindungsgemäße Kehrmaschine gemäß Anspruch 1 insbesondere durch einen solchen Saugkopf aus, bei welchem ein sich in Arbeitsrichtung vor dem Saugschacht erstreckendes flexibles flächiges Strömungsleitelement, welches den Zuströmbereich zu dem Saugschacht im Zusammenwirken mit der zu reinigenden Oberfläche düsenförmig begrenzt, bei gleichbleibender Position des Saugschachts mittels einer Verstelleinrichtung, welche an dem dem Saugschacht abgewandten Randbereich des flexiblen flächigen Strömungsleitelements angreift und mittels derer der dem Saugschacht abgewandte Rand des Strömungsleitelements zumindest im Wesentlichen linear - nämlich im Wesentlichen parallel zur zu reinigenden Oberfläche oder nur vergleichsweise gering zu dieser geneigt - verschiebbar ist, formveränderbar ist, und zwar dergestalt, dass die Geometrie des Strömungsleitelements zwischen einer relativ gewölbten Form mit einem relativ geringen Mindestabstand (= Spaltweite) zur zu reinigenden Oberfläche und einer relativ gestreckten Form mit einem relativ großen Mindestabstand zur zu reinigenden Oberfläche veränderbar ist. Entscheidend ist dabei, dass das flexible flächige Strömungsleitelement bei verschiedenen - mittels der Verstelleinrichtung veränderbaren - Spaltweiten eine den Zuströmbereich nach oben hin düsenartig begrenzende Funktion und Wirkung hat. Das heißt, bei einer Veränderung der Geometrie des Strömungsleitelements verändert sich zwar gemeinsam mit dem Mindestabstand (= Spaltweite) des Strömungsleitelements zu der zu reinigenden Oberfläche das Maß der Krümmung des Strömungsleitelements in dessen Scheitelpunkt; an der grundsätzlichen Funktionsweise des Strömungsleitelements als Begrenzung eines düsenartig ausgeführten Strömungswegs ändert sich durch eine solche Verstellung der Geometrie indessen nichts, somit kann der besagte düsenartige Strömungsweg optimal an die jeweils bestehenden Verhältnisse angepasst werden, und zwar idealer Weise stufenlos.This object is achieved according to the present invention by the recited in
Aufgrund dessen, dass der dem Saugschacht abgewandte Rand des Strömungsleitelements mittels der Verstelleinrichtung zumindest im Wesentlichen linear verschiebbar ist, wird beispielsweise die Realisierung der Verstelleinrichtung durch einen Hydraulikzylinder (oder mehrere Hydraulikzylinder) ermöglicht, und zwar ohne eine zusätzliche Mimik wie beispielsweise ein Umlenkgetriebe oder dergleichen. Dass der dem Saugschacht abgewandte Rand des Strömungsleitelements im Wesentlichen parallel zur zu reinigenden Oberfläche oder nur vergleichsweise gering zu dieser geneigt verschiebbar ist, gestattet die Ausführung des Saugkopfes - trotz einer Verstellbarkeit der Spaltweite innerhalb einer großen Bandbreite - mit einer vergleichsweise geringen Höhe des Saugkopfes, was günstig ist für die Möglichkeit, den Saugkopf in eine Transportstellung so weit von der zu reinigenden Oberfläche abzuheben, dass keine Gefahr der Beschädigung des Saugkopfes in der angehobenen Transportstellung durch Hindernisse besteht.Due to the fact that the edge of the flow guide element facing away from the suction channel is at least substantially linearly displaceable by means of the adjustment device, the realization of the adjustment device is made possible for example by a hydraulic cylinder (or several hydraulic cylinders), without additional facial expressions such as a deflection gear or the like. The fact that the edge of the flow guide element facing away from the suction shaft is substantially parallel to the surface to be cleaned or slidably displaced comparatively small, allows the execution of the suction head - despite an adjustability of the gap width within a wide range - with a comparatively small height of the suction head, which is favorable for the possibility to lift the suction head in a transport position so far from the surface to be cleaned, that no risk of Damage to the suction head in the raised transport position due to obstacles.
Eine in Arbeitsrichtung vergleichsweise kurze Ausführung des Saugkopfes lässt sich bei der vorstehend erläuterten Ausgestaltung der Erfindung insbesondere dann realisieren, wenn das flächige Strömungsleitelement entfernt von dem Saugschacht über eine Umlenkwalze geführt ist. Denn in diesem Fall braucht nicht für die gestreckte Geometrie des Strömungsleitelements frontseitig an dem Saugkopf Raum vorgehalten zu werden, dessen es bei der stark gewölbten Geometrie des Strömungsleitelements nicht bedarf. Allerdings geht eine solche Umlenkung des Strömungsleitelements typischerweise mit einer vergrößerten Bauhöhe des Saugkopfes einher, was sich im Einzelfall als weniger günstig erweisen kann. Und das flächige Strömungsleitelement ist - durch vergleichsweise geringe Eigensteifigkeit - an die Umlenkung anzupassen.In the above-described embodiment of the invention, a comparatively short embodiment of the suction head in the working direction can be realized, in particular, when the planar flow guide element is guided away from the suction shaft via a deflection roller. Because in this case does not need to be held at the front of the suction head space for the stretched geometry of the flow guide, which does not need it in the strongly curved geometry of the flow. However, such a deflection of the flow-guiding element is typically accompanied by an increased overall height of the suction head, which may prove less favorable in individual cases. And the planar flow guide is - by comparatively low inherent rigidity - adapt to the deflection.
Eine weitere Möglichkeit der konstruktiven Umsetzung der vorliegenden Erfindung besteht, wie in Anspruch 3 angegeben, darin, dass das Strömungsleitelement entfernt von dem Saugschacht auf eine Wickelwalze wickelbar ist. Der Vorteil der vergleichsweise geringen Abmessungen des Saugkopfes in Arbeitsrichtung gilt auch für diese Weiterbildung. Bevorzugt ist die Position des dem Saugschacht benachbarten Randes des Strömungsleitelements relativ zum Saugschacht fixiert. Die Position wird im Hinblick auf eine strömungstechnische und energetische Optimierung dabei besonders bevorzugt so gewählt, dass das Strömungsleitelement unmittelbar an den Saugschacht anschließt. Idealerweise ist dabei der dem Saugschacht unmittelbar benachbarte Randbereich des Strömungsleitelements fixiert und geometrisch solchermaßen festgelegt, dass ein stetiger Übergang vom Strömungsleitelement zum Saugschacht gewährleistet ist, und zwar unabhängig von der eingestellten Spaltweite. Die Vermeidung von Unstetigkeiten beim Übergang vom Strömungsleitelement zum Saugschacht trägt nicht nur - aufgrund der optimierten Strömungsverhältnisse - zu besonders guten Reinigungsergebnissen bei einer besonders geringen Leistungsaufnahme des Sauggebläses bei. Vielmehr ist dies auch im Hinblick auf die Geräuschemissionen günstig sowie im Hinblick auf den Wartungsaufwand, weil strömungstechnische Toträume, welche typischerweise zum sukzessiven Aufbau einer Verschmutzungsschicht neigen, vermieden werden.A further possibility of constructive implementation of the present invention consists, as stated in
Für die Ausführung des Strömungsleitelements kommen im Rahmen der vorliegenden Erfindung verschiedene Möglichkeiten in Betracht. So kann das Strömungsleitelement insbesondere als eine elastisch verformbare Strömungsleitplatte ausgeführt sein. Je nach den spezifischen Besonderheiten kann das flächige Strömungsleitelement dabei in seine maximal gestreckte, in seine maximale gewölbte oder aber jede beliebige Zwischenstellung vorgeformt sein, d.h. bei der betreffenden Geometrie frei sein von inneren Spannungen. Gemäß einer anderen bevorzugten Weiterbildung der vorliegenden Erfindung besteht das Strömungsleitelement aus einer Mehrzahl gelenkig miteinander verbundener Lamellen. In diesem Falle bauen sich typischerweise bei einer Änderung der Geometrie des Strömungsleitelements in diesem keine Spannungen auf. Eine solche Ausführungen des Strömungsleitelements erweist sich als vorteilhaft insbesondere dann, wenn es über eine Umlenkwalze umgelenkt oder auf eine Wickelwalze aufgewickelt wird (siehe oben). Die jeweilige Geometrie des Strömungsleitelements kann sich dabei frei, d.h. gemäß einer Kettenlinie einstellen, wenn das Strömungsleitelement zumindest bereichsweise frei nach unten in Richtung auf die zu reinigende Oberfläche "durchhängt". Letzteres ist indessen keineswegs zwingend. So kann beispielsweise auch eine Art Spannwalze - oder eine mehrere Spannwalzen umfassendes Spannwalzeneinheit - vorgesehen sein, welche den Scheitelpunkt des Strömungsleitelements vorgibt, wobei eine derartige Spannwalze insbesondere federbelastet vorgespannt sein kann. Ein vorteilhafter Aspekt der Ausführung des Saugkopfes mit (mindestens) einer Spannwalze ist die Möglichkeit, die Geometrie des Strömungsleitelements weiter beeinflussen zu können. Insbesondere im Hinblick auf eine optimale Düsenwirkung.For the execution of the flow guide come in the context of the present invention, various options into consideration. Thus, the flow guide can be designed in particular as an elastically deformable flow baffle. Depending on the specific features, the planar flow guide can be preformed in its maximum stretched, in its maximum arched or any intermediate position, ie at the geometry is free of internal tension. According to another preferred embodiment of the present invention, the flow guide element consists of a plurality of hingedly interconnected slats. In this case, typically no stresses build up in the case of a change in the geometry of the flow guide element in it. Such a design of the flow guide proves to be advantageous in particular when it is deflected over a guide roller or wound onto a winding roller (see above). The respective geometry of the flow-guiding element can thereby be free, ie set according to a chain line, if the flow-guiding element "sags" at least in regions freely downwards in the direction of the surface to be cleaned. The latter, however, is by no means compulsory. Thus, for example, a kind of tension roller - or a plurality of tension rollers comprehensive tension roller unit - may be provided which defines the apex of the flow, wherein such a tension roller may be biased in particular spring loaded. An advantageous aspect of the embodiment of the suction head with (at least) one tensioning roller is the possibility of being able to further influence the geometry of the flow guidance element. Especially with regard to an optimal nozzle effect.
