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 refers 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 the case of known machines, in which during the processing of raw materials, such as sliver or fleece and the like, from processed raw material or waste form, unwanted impurities arise in one Working area of the machine. Too many such Contamination in the working area of the machine can stop the operation of the machine or the resulting quality of through this adversely affect processed raw materials. Therefore are Such machines often with a machine-fixed suction provided that a large part of the lighter or smaller resulting from the processing Contamination or material waste from the work area away.

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 Absaugung 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 one of the operations of the Machine as little impairment as possible and therefore unfavorable place of the Work area arranged so that problem areas in the Work area exist by the standard suction not be detected or on which by the suction generated negative pressure for a sufficient cleaning effect is low. As a result, the work area must be such Machines at regular intervals by the operating personnel additionally cleaned manually to avoid excessive Accumulation of contaminants in the problem areas of the To prevent working 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 this is compressed air to the MascHine performed so that when the machine is turned off and on corresponding, the required cleaning or a Signal indicating necessary tool or workpiece change is output by the machine and the operating personnel Machine cover opened and thus the work area of the Has exposed the work area by means of a Compressed air gun can be blown clean.

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 to be removed or Material waste evenly further into the machine or into the space surrounding the machine, for example one Machine room, blown, so that the burden of the whole Hall with the unwanted impurities and raw material residues increases even if the specific area of the machine is clean appears.

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 use suction air instead of Compressed air to work.

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.By means of the permanently installed on the machine and with the stationary suction system connected to the machine tubular, flexible and in the work area of the Machine opening second suction air line according to the invention the problem areas of the machine are sucked free and the contamination is reliably removed from the machine. The Any dirt can be filtered and disposed of without straining the surroundings of the machine. They do Existing extraction 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 so clean maintained and maintenance and cleaning intervals can be clear be extended.

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 due to the lower fiber, particle and Particle pollution is kept clean, which increases overall a lower health burden for the operating personnel Machine results.
