Its free end (6) can be freely moved round the working area (A) to draw fly and trash into the suction plant. Also claimed is a method of using the above appts. Pref. the flexible hose (4) is connected to the filter housing (1) of a drawframe suction system which can have its own fan (11) or be operated from a central suction plant (14). Removal of the nozzle (6) from its holder (5) for manual cleaning of a stationary machine activates a switch to close off the suction to the stationary equipment (3) with a flap (10) so that the full capacity of the suction system is available to the hand nozzle (6).

Description

Die Erfindung betrifft eine Absaugvorrichtung zur Reinigung von Maschinen und bezieht sich auf eine Absaugvorrichtung gemäß dem Oberbegriff des Anspruchs 1. Sie betrifft auch ein Verfahren gemäß Anspruch 11.The invention relates to a suction device for cleaning machines and relates to a suction device according to the preamble of claim 1. It also relates to a method according to claim 11.

Bei bekannten Maschinen, bei denen sich während der Bearbeitung von Rohstoffen, wie Faserband oder Vlies und dergleichen, vom bearbeiteten Rohstoff stammende Materialabfälle oder Reste bilden, entstehen ungewollte Verunreinigungen in einem Arbeitsbereich der Maschine. Eine zu große Menge solcher Verunreinigungen im Arbeitsbereich der Maschine kann den Betrieb der Maschine oder die resultierende Qualität der durch diese bearbeiteten Rohstoffe nachteilig beeinflussen. Daher sind derartige Maschinen vielfach mit einer maschinenfesten Absaugung versehen, die bereits während der Bearbeitung einen Großteil der durch die Bearbeitung entstehenden leichteren oder kleineren Verunreinigungen oder Materialabfälle aus dem Arbeitsbereich entfernt.In known machines, in which material wastes or remnants originating from the processed raw material form during the processing of raw materials, such as sliver or fleece and the like, undesired contamination occurs in a working area of the machine. An excessive amount of such contaminants in the working area of the machine can adversely affect the operation of the machine or the resulting quality of the raw materials processed by it. Therefore, such machines are often provided with a machine-fixed suction system, which removes a large part of the lighter or smaller impurities or material waste resulting from the processing from the work area even during processing.

Meist ist jedoch die Absaugöffnung an einer den Betrieb der Maschine möglichst wenig beeinträchtigenden und damit hinsichtlich der Absaugleistung ungünstigen Stelle des Arbeitsbereichs angeordnet, so daß Problemzonen im Arbeitsbereich vorhanden sind, die von der Standard-Absaugung nicht erfaßt werden oder an denen der durch die Ansaugung erzeugte Unterdruck für eine ausreichende Reinigungswirkung zu gering ist. Infolgedessen muß der Arbeitsbereich solcher Maschinen in regelmäßigen Abständen durch das Bedienpersonal zusätzlich manuell gereinigt werden, um eine übermäßige Ansammlung der Verunreinigungen in den Problemzonen des Arbeitsbereichs der Maschine zu verhindern.Mostly, however, the suction opening is arranged at a location of the work area that has as little impact as possible on the operation of the machine and is therefore unfavorable with regard to the suction power, so that problem areas are present in the work area that are not covered by the standard suction or at which the one generated by the suction Vacuum is too low for a sufficient cleaning effect. As a result, the work area of such machines must be periodically cleaned manually by the operating personnel to prevent excessive contamination in the problem areas of the work area of the machine.

Bei den bekannten Maschinen wird hierzu Preßluft an die MascHine geführt, so daß dann, wenn die Maschine abgeschaltet und ein entsprechendes, die erforderliche Reinigung oder einen notwendigen Werkzeug- oder Werkstückwechsel anzeigendes Signal durch die Maschine ausgegeben wird und das Bedienpersonal die Maschinenabdeckung geöffnet und damit den Arbeitsbereich der Maschine freigelegt hat, der Arbeitsbereich mittels einer Preßluftpistole reinigend ausgeblasen werden kann.In the known machines, compressed air is fed to the MascHine for this purpose, so that when the machine is switched off and a corresponding signal indicating the necessary cleaning or a necessary tool or workpiece change is given is issued by the machine and the operating personnel has opened the machine cover and thus has exposed the working area of the machine, the working area can be blown out with a compressed air gun for cleaning.

Hierbei werden jedoch die zu entfernenden Verunreinigungen oder Materialabfälle gleichmäßig weiter in die Maschine hinein oder in den die Maschine umgebenden Raum, beispielsweise einen Maschinensaal, geblasen, so daß die Belastung des gesamten Saales mit den unerwünschten Verunreinigungen und Rohstoffresten zunimmt, auch wenn der spezifische Bereich der Maschine sauber erscheint.Here, however, the impurities or material wastes to be removed are blown evenly further into the machine or into the space surrounding the machine, for example a machine room, so that the load on the entire room with the undesired impurities and raw material residues increases, even if the specific area of the Machine appears clean.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Maschinenreinigung zu schaffen, die Problemzonen des Arbeitsbereichs einer Maschine ohne Belastung des die Maschine umgebenden Raums reinigen kann.The invention is therefore based on the object of providing machine cleaning which can clean problem areas of the working area of a machine without stressing the space surrounding the machine.

Diese Aufgabe wird mit Anspruch 1 oder 11 gelöst. Charakteristisch für die Lösungen ist es, mit Saugluft statt mit Druckluft zu arbeiten.This object is solved with claim 1 or 11. It is characteristic of the solutions to work with suction air instead of compressed air.

Mittels der an der Maschine fest installierten und mit der stationären Absauganlage der Maschine verbundenen schlauchförmigen, flexiblen und in den Arbeitsbereich der Maschine sich öffnenden zweiten Absaugluftleitung werden erfindungsgemäß die Problemzonen der Maschine freigesaugt und die Verunreinigungen zuverlässig aus der Maschine entfernt. Der anfallende Schmutz kann einer Filterung und Entsorgung zugeführt werden, ohne die Umgebung der Maschine zu belasten. Die schon vorhandene Absauganlage erhält einen doppelten Zweck; Kosten können eingespart werden.According to the invention, the problem areas of the machine are sucked free and the contaminants are reliably removed from the machine by means of the second suction air line, which is permanently installed on the machine and connected to the stationary suction system of the machine and opens into the working area of the machine. The dirt can be filtered and disposed of without polluting the area around the machine. The existing suction system has a dual purpose; Costs can be saved.

Der Produktions- oder Innenraum der Maschine wird so sauber gehalten und Wartungs- und Reinigungsintervalle können deutlich verlängert werden.The production or interior of the machine is kept clean and maintenance and cleaning intervals can be extended significantly.

Ferner wird erreicht, daß die Luft in der Maschinen- oder produktionshalle aufgrund der geringeren Faser-, Teilchen- und Partikelbelastung rein gehalten wird, wodurch sich insgesamt eine geringere gesundheitliche Belastung des Bedienpersonals der Maschine ergibt.It is also achieved that the air in the machine or production hall is kept clean due to the lower fiber, particle and particle load, which results in a lower overall health burden for the operating personnel of the machine.

Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous embodiments of the invention are specified in the dependent claims.

Die Erfindung ist nicht auf Strecken beschränkt. Sie kann ebenso bei Karden, Kämmaschinen oder ähnlichen Maschinen eingesetzt werden.The invention is not limited to routes. It can also be used on cards, combing machines or similar machines.

Figur 1 zeigt in vereinfachter Darstellung Teile einer Absauganlage in Verbindung mit dem sauganschluß bzw. der Absaugvorrichtung an einer Strecke einer Spinnerei, um während des Streckvorgangs anfallende Fasern oder Faserreste abzusaugen.FIG. 1 shows a simplified representation of parts of an extraction system in connection with the suction connection or the extraction device on a stretch of a spinning mill, in order to extract fibers or fiber residues arising during the stretching process.

In einem Filtergehäuse 1, welches beispielsweise als Filterkasten ausgebildet ist oder Teile einer Filteranlage umschließt, ist ein Filter oder Sieb 2 angeordnet. Der Filter 2 trennt das Filtergehäuse 1 in einen Bereich 1a mit teilchen-, faser- oder partikelhaltiger Luft, in den die aus dem Arbeitsbereich A der Maschine abgesaugte Luft eingeleitet wird, und einen in stromab auf der Rückseite des Filters 2 befindlichen Rein- oder Abluftbereich 1b. Der Filter 2 ist ausreichend feinporig ausgebildet, um Teilchen, Fasern oder Partikel einer vorbestimmten Größe zurückzuhalten.A filter or sieve 2 is arranged in a filter housing 1, which is designed, for example, as a filter box or encloses parts of a filter system. The filter 2 separates the filter housing 1 into an area 1a with air containing particles, fibers or particles, into which the air extracted from the work area A of the machine is introduced, and into a clean or exhaust air area located downstream on the back of the filter 2 1b. The filter 2 is of sufficiently fine-pored design to retain particles, fibers or particles of a predetermined size.

In dem Bereich 1a mit zu reinigender Luft endet in einer Wandung des Filtergehäuses 1 eine erste Absaugluftleitung 3 sowie eine zweite Absaugluftleitung 4. Die erste pbsaugluftleitung 3 endet stationär in dem Arbeitsbereich A der Maschine. Die zweite Absaugluftleitung 4 ist zumindest abschnittsweise flexibel als Schlauch ausgeführt und umfaßt an ihrem in dem Arbeitsbereich A der Maschine sich öffnenden Ende eine Saugdüse 6 mit einer Ansaugöffnung.In the area 1a with air to be cleaned, a first suction air line 3 and a second suction air line 4 end in a wall of the filter housing 1. The first suction air line 3 ends stationary in the working area A of the machine. The second suction air line 4 is flexible, at least in sections Hose designed and comprises at its end opening in the working area A of the machine, a suction nozzle 6 with a suction opening.

Eine Haltevorrichtung 5 dient während der Zeit, während der die Saugdüse 6 nicht benötigt wird, zur Arretierung der Saugdüse 6 und damit der zweiten Saugluftleitung 4 nahe der Maschine. Die Haltevorrichtung 5 umfaßt eine Saugdüsen-Verschlußvorrichtung 7, die während der Ablage und Arretierung der Saugdüse 6 für einen zuverlässigen (im wesentlichen luftdichten) Anschluß der zweiten Luftleitung 4 sorgt.A holding device 5 is used for locking the suction nozzle 6 and thus the second suction air line 4 near the machine during the time when the suction nozzle 6 is not required. The holding device 5 comprises a suction nozzle closure device 7, which ensures a reliable (essentially airtight) connection of the second air line 4 during the placement and locking of the suction nozzle 6.

Eine mit der Vorrichtung 5 verbundene Umschalteinrichtung 8, beispielsweise ein Schalter oder Fühler, dient zum Umschalten zwischen dem normalen Betrieb der Maschine und einem Hand- bzw. Reinigungsbetrieb. Die Umschalteinrichtung 8 kann hierzu manuell betätigbar ausgeführt sein oder bei Entnahme der Saugdüse 6 der zweiten Absaugluftleitung 4 aus der Halteeinrichtung 5 und/oder beim Wiedereinlegen der Saugdüse 6 in die Halfevorrichtung 5 selbsttätig schalten.A switching device 8 connected to the device 5, for example a switch or sensor, serves to switch between normal operation of the machine and manual or cleaning operation. For this purpose, the switching device 8 can be designed to be manually operable or to switch automatically when the suction nozzle 6 of the second suction air line 4 is removed from the holding device 5 and / or when the suction nozzle 6 is reinserted into the holding device 5.

Die Umschaltung erfolgt gesteuert durch eine elektrische Steuerung 9, die in Antwort auf eine Betätigung der Umschalteinrichtung 8, beispielsweise bei Entnahme der zweiten Absaugluftleitung 4 aus der Arretierungsvorrichtung 5, eine im Filtergehäuse 1 in der Nähe der Mündung der ersten Absaugluftleitung 3 angeordnete Absaugluft-Sperreinrichtung 10 betätigt, um die Mündungsöffnung der ersten (stationären) Absaugluftleitung 3 zu verschließen, während die Mündungsöffnung der zweiten Absaugluftleitung 4 geöffnet bleibt.The switchover is controlled by an electrical controller 9, which, in response to actuation of the switchover device 8, for example when the second suction air line 4 is removed from the locking device 5, has an exhaust air blocking device 10 arranged in the filter housing 1 near the mouth of the first suction air line 3 actuated to close the opening of the first (stationary) suction air line 3, while the opening of the second suction air line 4 remains open.

Die Absaugluft-Sperreinrichtung 10 kann als Klappe oder Schieber ausgebildet sein, wobei eine Anordnung derselben sowohl im Innern des Filtergehäuses 1 als auch innerhalb der ersten Absaugluftleitung 3, beispielsweise in Form einer Drosselklappe, möglich ist.The suction air blocking device 10 can be designed as a flap or slide, an arrangement of which is possible both inside the filter housing 1 and within the first suction air line 3, for example in the form of a throttle valve.

Im Filtergehäuse 1 auf der rückwärtigen Seite des Filters 2 ist ein Ventilator bzw. Gebläse 11 angeordnet, welches von einem Riemenantrieb 12,13 von der Außenseite des Filtergehäuses 1 her in Drehung versetzt wird und den zur Absaugung der Verunreinigungen erforderlichen Unterdruck erzeugt. Der Antrieb 12 kann hierbei als Elektromotor ausgebildet sein, dessen Betrieb ebenfalls mittels der elektronischen Steuerung 9 gesteuert wird.In the filter housing 1 is on the rear side of the filter 2 a fan or blower 11 is arranged, which is set in rotation by a belt drive 12, 13 from the outside of the filter housing 1 and generates the vacuum required to extract the contaminants. The drive 12 can be designed as an electric motor, the operation of which is also controlled by means of the electronic control 9.

Alternativ zur Einleitung der verunreinigten Luft in das Filtergehäuse 1 kann auch ein Anschluß der Maschine an eine zu einer zentralen Absauganlage führende Absaugleitung 14 vorgesehen sein. In diesem Fall kann vorgesehen sein, daß die erste Saugluftleitung 3 weiterhin in ein Filtergehäuse 1 der beschriebenen Art mündet und dort vorgefiltert wird, oder unter Wegfall des Filtergehäuses 1 direkt in die von der Maschine wegführende Absaugleitung 14 geleitet wird, während die zweite Absaugluftleitung 4 direkt in die Absaugleitung 14 einmündet.As an alternative to introducing the contaminated air into the filter housing 1, the machine can also be connected to a suction line 14 leading to a central suction system. In this case it can be provided that the first suction air line 3 continues into a filter housing 1 of the type described and is pre-filtered there, or is passed directly to the suction line 14 leading away from the machine while the filter housing 1 is omitted, while the second suction air line 4 directly opens into the suction line 14.

Es kann vorgesehen sein, daß die Absaugluft-Sperreinrichtung 10 weiterhin in der Nähe der Mündungsstelle der ersten Absaugluftleitung 3 angeordnet ist, wobei auf diese Weise die Steuerung der Absaugluft-Sperreinrichtung 10 vorteilhaft nahe bei der Maschine verbleiben und eine Filterung und Entsorgung der Abluft insgesamt an einer von der Maschine entfernten zentralen Stelle eines Produktionsablaufs erfolgen kann.It can be provided that the suction air blocking device 10 is further arranged in the vicinity of the mouth of the first suction air line 3, the control of the suction air blocking device 10 advantageously remaining close to the machine and filtering and disposal of the exhaust air as a whole a central point of a production process remote from the machine.

Alternativ kann bei ausreichender Unterdruckleistung der zentralen Absauganlage die Absaugluft-Sperreinrichtung 10 gänzlich entfallen, so daß die erste Absaugluftleitung ständig geöffnet bleibt und fortlaufend absaugt, und ein Luftabschluß der zweiten Absaugleitung 4 während deren Nichtgebrauchs ausschließlich über eine geeignete Ausgestaltung der Haltevorrichtung 5 erfolgt.Alternatively, if the central suction system has a sufficient negative pressure output, the suction air blocking device 10 can be dispensed with entirely, so that the first suction air line remains open and continuously suctioned, and the second suction line 4 is sealed off from the air when it is not in use only by means of a suitable design of the holding device 5.

Figur 2 zeigt eine Vorderansicht einer Strecke mit dem zusätzlichen Sauganschluß 15,16, wobei der Anschluß der Saugvorrichtung an eine zentrale Absauganlage 14 dargestellt ist. In durchbrochener Linie ist die Absaugleitung 14 angedeutet, in welche oberhalb der Strecke die zweite Absaugluftleitung 4 einmündet. Die zweite Absaugluftleitung 4 ist verschwenkbar über eine an der Maschine angeordnete Haltevorrichtung 15 in Bediennähe installiert. Die zweite Absaugluftleitung 4 ist in der Nähe ihres die Saugdüse 6 tragenden Endes 16 mit Überlänge an einer variabel ausziehbaren Halterung 17 griffbereit gehalten. Durch Ziehen am Ende 16 ist eine Verlängerung der zweiten Absaugluftleitung 4 so möglich, daß mit der Saugdüse 6 alle in Bediennähe vorhandenen Problemzonen der Strecke erreichbar sind.FIG. 2 shows a front view of a section with the additional suction connection 15, 16, the connection of the suction device to a central suction system 14 being shown. The suction line 14, into which the second suction air line 4 opens above the route, is indicated in a broken line. The second suction air line 4 is pivotally installed near the operator via a holding device 15 arranged on the machine. The second suction air line 4 is kept close at hand on its end 16 carrying the suction nozzle 6 with excess length on a variably extendable holder 17. By pulling the end 16, an extension of the second suction air line 4 is possible in such a way that all problem zones of the route that are close to the operator can be reached with the suction nozzle 6.

Figur 3 zeigt eine Aufsucht auf die Strecke, in der in durchbrochener Linie die Absaugleitung 14 sowie ein möglicher Verlauf der Haltevorrichtung 15 mit der flexiblen Absaugluftleitung 16 erkennbar sind.Figure 3 shows a visit to the route in which the suction line 14 and a possible course of the holding device 15 with the flexible suction air line 16 can be seen in a broken line.

Gemäß dem Ausführungsbeispiel ist eine fest an der Maschine angeordnete schlauchförmige Absaugleitung 4, 16 dargestellt. Erfindungsgemäß ist es aber ausreichend, wenn die Maschine eine Anschlußmöglichkeit für eine derartige Absaugluftleitung 4, 16 vorgesehen ist, welche mit der Absauganlage der Maschine verbunden ist. An einen derartigen Anschluß ist bei einer Reinigung der Maschine ein Saugschlauch anschließbar. Dieser Schlauch ist nach Beendigung der Reinigung wieder von der Maschine entfernbar und für die Reinigung einer anderen Maschine einsetzbar.According to the exemplary embodiment, a tubular suction line 4, 16 which is fixedly arranged on the machine is shown. According to the invention, however, it is sufficient if the machine is provided with a connection option for such a suction air line 4, 16, which is connected to the suction system of the machine. A suction hose can be connected to such a connection when cleaning the machine. This hose can be removed from the machine after cleaning and can be used to clean another machine.
