Description

Die Erfindung betrifft ein Saugschlitzkanalabsaugsystem mit einer in oder an einem Saugschlitzkanal geführten Saugdüse, welche gegenüber dem Kanal mittels mindestens einer Dichtlippe abgedichtet ist, sowie eine entsprechende Saugdüse und eine Dichtlippe für ein solches System.The invention relates to a Saugschlitzkanalabsaugsystem with a guided in or on a Saugschlitzkanal suction nozzle, which is sealed against the channel by means of at least one sealing lip, and a corresponding suction nozzle and a sealing lip for such a system.

Aus der DE 44 22 731 ist eine Saugschlitzkanal-Absaugvorrichtung bekannt, vermittels welcher Gase und Dämpfe absaugbar sind. Dabei wird an der Decke der Werksatt ein an einem Sauggebläse angeschlossener Kanal befestigt, an dem ein beweglicher Ansaugstutzen geführt ist, an dem wiederum ein Saugschlauch angeschlossen ist. Die Abdichtung des Ansaugstutzens gegenüber dem Kanal erfolgt dabei über eine Lippendichtung.From the DE 44 22 731 a Saugschlitzkanal suction device is known, by means of which gases and vapors are sucked. In this case, a connected to a suction fan duct is attached to the ceiling of the factory seat, on which a movable intake is performed, to which in turn a suction hose is connected. The sealing of the intake manifold with respect to the channel takes place via a lip seal.

Der Vorteil hierbei liegt darin, dass auf dem Werkstattboden keine unhandlichen Gerätschaften herumstehen.The advantage here is that there are no bulky implements left on the workshop floor.

Bei Lebensmittelmärkten geht der Trend zu frisch aufgebackenen Backwaren, die naturgemäß eine Staub- und eine erhebliche Krümelbelastung des Verkaufsraums mit sich führen.In food markets, the trend is towards freshly baked baked goods, which naturally entail a dust and a considerable crumb load on the sales area.

Da bei starker Partikelbelastung hohe Saugleistungen und eine gute Systemabdichtung notwendig sind, sind die vorliegenden Ansätze zur reinen Gasabsaugung unzureichend. Auch sind die vorbekannten Lösungen schwerfällig und durch Reinigungspersonal nur bedingt bedienbar.Since high suction power and a good system sealing are necessary for heavy particle load, the present approaches to pure gas extraction are insufficient. Also, the previously known solutions are cumbersome and only partially serviceable by cleaning personnel.

Es besteht daher der Wunsch nach effizienten und hygienischen Reinigungseinrichtungen, die in Form von fest installierten Systemen bereitgestellt sind.There is therefore a desire for efficient and hygienic cleaning facilities, which are provided in the form of permanently installed systems.

Aus der US 2007/0209545 A1 ist ein Saugkanalsystem bekannt, bei dem ein Schlitten in einem gegenüber diesem gegen die Umluft mit einer Art Lippendichtung abgedichteten Kanal geführt ist.From the US 2007/0209545 A1 a Saugkanalsystem is known in which a carriage is guided in a respect to this against the circulating air sealed with a kind of lip seal channel.

Aus der DD 75140 A5 und der US 3,913,470 A ist jeweils ein Kanalabsaugsystem mit einem in einem Kanal geführten navetteförmigen Schlitten als Ansaugstutzen gezeigt.From the DD 75140 A5 and the US 3,913,470 A In each case a Kanalabsaugsystem with a run in a channel navette-shaped slide is shown as the intake manifold.

Nachteilig bei den vorgenannten Anordnungen ist, dass eine verlässliche Abdichtung, bei der Staubaustritt verhindert ist, ohne, dass starke Reibungsverluste oder Friktionen auftreten nicht möglich ist.A disadvantage of the aforementioned arrangements is that a reliable seal, is prevented in the dust, without that strong friction losses or frictions occur is not possible.

Aufgabe der Erfindung ist es, ein verbessertes Saugschlitzkanalabsaugsystem mit einer in oder an einem Saugschlitzkanal geführten Saugdüse, welche gegenüber dem Kanal mittels mindestens einer Dichtlippe abdichtet, sowie eine entsprechende Saugdüse und eine Dichtlippe für ein solches System zur Verfügung zu stellen, bei der eine bessere Abdichtung bei leichter Handhabung bereitgestellt ist.The object of the invention is to provide an improved Saugschlitzkanalabsaugsystem with a guided in or on a Saugschlitzkanal suction nozzle, which seals against the channel by means of at least one sealing lip, and to provide a corresponding suction nozzle and a sealing lip for such a system in which a better seal provided with ease of use.

Diese Aufgabe wird durch eine Saugdüse nach den Merkmalen des Anspruchs 1, ein Saugschlitzkanalabsaugsystem nach den Merkmalen des Anspruchs 6 sowie einer Dichtlippe nach Anspruch 5 gelöst.This object is achieved by a suction nozzle according to the features of claim 1, a Saugschlitzkanalabsaugsystem according to the features of claim 6 and a sealing lip according to claim 5.

Erfindungsgemäß ist eine Saugdüse für ein Saugschlitzkanalabsaugsystem vorgeschlagen, welches die Saugdüse in oder an einem Saugschlitzkanal führt, welcher mittels mindestens einer Dichtlippe gegenüber einem Ansaugstutzen der beweglich geführten Saugdüse abgedichtet ist, wobei das Saugschlitzkanal-seitige Ende des Ansaugstutzens einen überstehenden Wulst aufweist, der zur Anlage an der/den Dichtlippen vorgesehen ist. Hierdurch ist auf besonders effektive Weise eine leichtere Handhabung bei verbesserter Abdichtung ermöglicht, da Dichtlippen im Wesentlichen am Wulst der Saugdüse abdichten. Im weiteren zeichnet sich die Erfindung dadurch aus, dass, um das Gleiten gegenüber der Dichtlippe zu verbessern, vorgesehen ist, dass wenigstens der Wulst des Ansaugstutzens mit einer strukturierten nichtplanen Oberfläche versehen ist. Dies kann durch eine hammerschlaglackartige Oberflächenstruktur vorgesehen sein. Dies kann durch eine Beschichtung mit Pulverlack oder Strukturlack bewerkstelligt sein.According to the invention, a suction nozzle for a Saugschlitzkanalabsaugsystem is proposed, which leads the suction nozzle in or on a Saugschlitzkanal which is sealed by means of at least one sealing lip against a suction nozzle of the movably guided suction nozzle, wherein the Saugschlitzkanal-side end of the intake manifold has a protruding bead, the plant is provided on the / the sealing lips. As a result, an easier handling with improved sealing is possible in a particularly effective manner, since sealing lips seal substantially at the bead of the suction nozzle. Furthermore, the invention is characterized in that, in order to improve the sliding relative to the sealing lip, it is provided that at least the bead of the intake manifold is provided with a structured non-planar surface. This can be provided by a hammer impact paint-like surface structure. This can be accomplished by a coating with powder coating or textured paint.

Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgeschlagen, dass die Saugdüse zum Saugschlitzkanal-seitigen Ende hin in einer Raumrichtung sich verjüngend abflachend , und in einer hierzu senkrechten Raumrichtung sich aufweitend und die Öffnung des Ansaugstutzens im Querschnitt oval, spitz zulaufend ausgestaltet ist. Hierdurch wird eine Saugleistungs-verlustarme Überführung von einem an der Saugdüse angeschlossenen Saugschlauch über die Saugdüse zum Saugschlitzkanal ermöglicht. Die vorgeschlagene Navette-ähnliche Form des Wulstes, also näherungsweise dem Schnitt zweier Kreisbögen, ermöglicht ein gutes Hindurchgleiten der Saugdüse bei beidseitig vorgesehenen Dichtlippen. Durch den Unterdruck im Saugschlitzkanal liegen die Dichtlippen vor und nach dem Ansaugstutzen der Saugdüse dichtend aneinander an. Mit der vorliegenden Erfindung ist sogar ein Einsatz mit Hochvakuum denkbar, da selbst bei den dann verstärkt auftretenden Kräften eine Beweglichkeit erhalten bleibt.According to an advantageous embodiment of the invention it is proposed that the suction nozzle to the Saugschlitzkanal-side end in a spatial direction tapering flattening, and in a spatial direction perpendicular thereto widening and the opening of the intake in oval cross-section, tapering is designed. In this way, a low-suction low-loss transfer from a suction hose connected to the suction nozzle via the suction nozzle to Saugschlitzkanal is possible. The proposed Navette-like shape of the bead, so approximately the intersection of two circular arcs, allows a good sliding of the suction nozzle at both sides provided sealing lips. Due to the negative pressure in Saugschlitzkanal the sealing lips are before and after the intake of the suction nozzle sealingly against each other. With the present invention, even use with high vacuum is conceivable, since even with the then increasingly occurring forces mobility is maintained.

Bevorzugterweise bleibt der Querschnitt des sich in einer Raumrichtung abflachenden und in einer senkrechten Raumrichtung hierzu aufweitenden Ansaugstutzens annähernd gleich.Preferably, the cross section of the flattening in a direction in space and in a vertical spatial direction widening thereto intake remains approximately the same.

Nach einem zweiten Aspekt der Erfindung ist eine Dichtlippe für ein Saugschlitzkanalabsaugsystem mit einer Saugdüse, welche in oder an einem Saugschlitzkanal geführt ist, welcher mittels mindestens einer Dichtlippe gegenüber einem Ansaugstutzen der beweglich geführten Saugdüse abgedichtet ist, vorgeschalagen, wobei die Dichtlippe aus einem Verbundwerkstoff aus elastischem Material besteht, wobei an der einem vorbei gleitendem Ansaugstutzen zugewandten Seite ein gegenüber diesem reibungsarmes Material vorgesehen ist, wobei an der einem vorbei gleitendem Ansaugstutzen zugewandten Seite eine Riffelung oder ein Gewebe angeordnet ist, dessen dem Ansaugstutzen unmittelbar zugewandte Riffeln oder Fasern in Richtung der Gleitrichtung ausgerichtet sind.According to a second aspect of the invention, a sealing lip for a Saugschlitzkanalabsaugsystem with a suction nozzle, which is guided in or on a Saugschlitzkanal, which is sealed by means of at least one sealing lip against an intake manifold of the movably guided suction nozzle, voralagen, wherein the sealing lip of a composite material of elastic Material is provided, wherein on the one past sliding intake port side facing a low-friction material is provided, wherein on the passing past a sliding intake side facing a corrugation or a fabric is arranged, the intake directly facing corrugations or fibers aligned in the direction of sliding are.

Vorteilhafterweise ist das reibungsarme Material ein Polyestergewebe, wobei die Faserrichtung an der dem Wulst zugewandten Seite im Wesentlichen in Bewegungsrichtung der Saugdüse am Saugschlitzkanal angeordnet ist. Hierdurch wird das Abgleiten auf dem Gewebe des Verbundstoffs der Dichtlippe nochmals verbessert. Durch die Faseranordnung senkrecht zur Saugrichtung zum Saugschlitzkanal-Inneren hin ist zudem nochmals die Abdichtung der Dichtlippen durch Aneinanderliegen der gegenüberliegenden Fasern der Dichtlippen verbessert.Advantageously, the low-friction material is a polyester fabric, wherein the fiber direction is arranged on the side facing the bead substantially in the direction of movement of the suction nozzle on Saugschlitzkanal. As a result, the sliding on the fabric of the composite material of the sealing lip is further improved. Due to the fiber arrangement perpendicular to the suction direction to Saugschlitzkanal-inside towards the seal of the sealing lips is also improved by juxtaposition of the opposite fibers of the sealing lips.

Nach dem dritten Aspekt der Erfindung ist ein Saugschlitzkanalabsaugsystem mit einer Saugdüse nach einem der Ansprüche 1 bis 4 und/oder einer Dichtlippe nach Anspruch 5 vorgeschlagen.According to the third aspect of the invention, a Saugschlitzkanalabsaugsystem with a suction nozzle according to one of claims 1 to 4 and / or a sealing lip according to claim 5 is proposed.

Von Vorteil ist die Saugdüse in einer Zwangsführung am Saugschlitzkanal geführt und weist hierzu nach einer Weiterbildung insbesondere in einer am oder im Saugschlitzkanal ausgebildeten Schlitzführung gelagerte Rollen auf.Advantageously, the suction nozzle is guided in a positive guide on Saugschlitzkanal and has for this purpose according to a further development, in particular in a formed on or in Saugschlitzkanal slot guide rollers.

Bevorzugterweise besteht die Dichtlippe an ihrer dem Wulst des Ansaugstutzens zugewandten Seite aus möglichst gegenüber diesem reibungsarmen Material, wobei insbesondere noch durch eine Oberflächenwahl in Form eine Riffelung oder eines Gewebes eine Bevorzugung des Gleitens in Bewegungsrichtung der Saugdüse am Schlitzkanal gegeben sein kann. Eine solche Riffelung oder Gewebestruktur kann auch der Abdichtung gegen die Saugwirkung zum Kanalinneren der Dichtlippen verbessern.Preferably, the sealing lip is on its side facing the bead of the intake from as possible with respect to this low-friction material, in particular by a surface choice in the form of a corrugation or a tissue may be given a preference of sliding in the direction of movement of the suction nozzle on the slot channel. Such a corrugation or fabric structure can also improve the seal against the suction to the channel interior of the sealing lips.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den weiteren Unteransprüchen oder deren mögliche Unterkombinationen.Further advantageous embodiments will become apparent from the other dependent claims or their possible sub-combinations.

In Fig. 1 ist das ganze Saugschlitzkanalabsaugsystem 11 mit einer Saugdüse 1 gezeigt, welche über einen Saugwagen 4 an einem Saugschlitzkanal 2 geführt ist. Der Saugschlitzkanal 2 wird dabei über einen Sauggebläseanschluss 22 mit einem Sauggebläse (nicht dargestellt) verbunden.In Fig. 1 the entire Saugschlitzkanalabsaugsystem 11 is shown with a suction nozzle 1, which is guided via a suction carriage 4 to a suction slot 2 channel. The Saugschlitzkanal 2 is connected via a suction fan connection 22 with a suction fan (not shown).

Die Abdichtung des Saugschlitzkanals 2 gegen die Saugdüse 1 erfolgt dabei durch die symmetrisch angeordneten flexiblen Dichtlippen 31 und 32. Im Bereich neben der Saugdüse liegen die Dichtlippen 31 und 32 aneinander dichtend an, siehe hierzu auch Fig. 3, in der ein Schnitt durch das Saugschlitzkanalabsaugsystem 11 neben dem Saugwagen 4 gezeigt ist. Der Saugschlitzkanal 2 ist vermittels der aneinanderliegenden Dichtlippen 31 und 32 dicht verschlossen. Die Saugleistung wird so auch über längere Wege nicht verringert und die partikelbelastete Abluft kann im Saugschlitzkanal 2 sicher zum Sauggebläseanschluss 22 geleitet werden, ohne dass es zu Verschmutzung außerhalb des Saugschlitzkanals 2 durch freiwerdende Krümel oder Partikel kommt.The sealing of the suction slot 2 against the suction nozzle 1 takes place through the symmetrically arranged flexible sealing lips 31 and 32. In the area next to the suction nozzle, the sealing lips 31 and 32 abut against each other, see also Fig. 3 in which a section through the Saugschlitzkanalabsaugsystem 11 is shown adjacent to the suction truck 4. The Saugschlitzkanal 2 is sealed by means of the adjacent sealing lips 31 and 32. The suction power is not reduced so even over longer distances and the particulate exhaust air can be safely routed to Sauggebläseanschluss 22 in Saugschlitzkanal 2, without causing pollution outside the Saugschlitzkanals 2 by liberated crumbs or particles.

An dem an der Saugdüse 1 vorgesehenen Schlauchanschluss 16 wird dann der Saugschlauch angeschlossen, der bis nahe dem Boden des Raumes reicht, in dem das System installiert ist.At the provided on the suction nozzle 1 hose connection 16 then the suction hose is connected, which extends to near the bottom of the room in which the system is installed.

Eine schematische Schnittdarstellung durch das Saugschlitzkanalabsaugsystem 11 und den Saugwagen 4 mit daran befestigter Saugdüse 1 ist in Fig. 2 gezeigt.A schematic sectional view through the Saugschlitzkanalabsaugsystem 11 and the suction carriage 4 with attached suction nozzle 1 is in Fig. 2 shown.

Das Saugschlitzkanal-seitige Ende 14 des Ansaugstutzens 12 der Saugdüse 1 weist einen überstehenden Wulst 13 auf, der an den Dichtlippen 31, 32 anliegt.The Saugschlitzkanal-side end 14 of the intake manifold 12 of the suction nozzle 1 has a protruding bead 13 which rests against the sealing lips 31, 32.

In dieser Schnittdarstellung ist auch gut ersichtlich, wie die Saugdüse 1 über den daran befestigten Saugwagen 4 in einer Zwangsführung am Saugschlitzkanal 2 geführt ist. Am Saugwagen 4 gelagerte Rollen 15 sind hierzu in einer am Saugschlitzkanal 2 ausgebildeten Schlitzführung 21 geführt.In this sectional view, it is also easy to see how the suction nozzle 1 is guided via the suction carriage 4 attached thereto in a positive guide on the suction slot channel 2. Rollers 15 mounted on the suction carriage 4 are guided for this purpose in a slot guide 21 formed on the suction slot channel 2.

Die Dichtlippen 31 und 32 sind im Beispiel an ihrer dem Wulst 13 des Ansaugstutzens 12 zugewandten Seite aus einem möglichst gegenüber dem Wulst-Oberflächenmaterial reibungsarmen technischem Polyestergewebe ausgebildet.The sealing lips 31 and 32 are formed in the example on its side facing the bead 13 of the intake 12 from a possible low friction with respect to the bead surface material technical polyester fabric.

In den Fig. 4a bis 4c ist der Saugwagen 4 mit der Saugdüse 1 und deren Ansaugstutzen 12 mit am Ende vorgesehenem Wulst 13 aus verschiedenen Blickrichtungen gezeigt.In the Fig. 4a to 4c is the suction carriage 4 with the suction nozzle 1 and the intake manifold 12 shown at the end of the bead 13 from different perspectives.

Der annähernd Navette-förmige Wulst 13, steht gegenüber dem Ansaugstutzen 12 über.The approximately Navette-shaped bead 13, is opposite to the intake 12 via.

Die Saugdüse 1 bzw. deren Ansaugstutzen 12 ist sich abflachend verjüngend zum Saugschlitzkanal-seitigen Ende 14 hin ausgestaltet. Zum einen ist sie sich verjüngend in einer ersten Raumrichtung und in einer hierzu senkrechten Raumrichtung sich aufweitend ausgestaltet. Hierdurch bleibt die Querschnittsweite ohne Verluste erhalten. Die Öffnung des Ansaugstutzens 12 ist, wie der Wulst 13, im Querschnitt oval, spitz zulaufend ausgestaltet.The suction nozzle 1 or its intake manifold 12 is flattening tapered to Saugschlitzkanal-side end 14 out. On the one hand, it is tapered in a first spatial direction and in a spatial direction perpendicular thereto, designed to widen. As a result, the cross-sectional width is maintained without losses. The opening of the intake manifold 12, like the bead 13, oval in cross-section, designed tapering.
