Abstract

A process is disclosed for cleaning thread- or strip-shaped articles, in particular wire, by ultrasound emitted by an ultrasonic sonotrode and a liquid, according to DE-196 02 917.1-15. The object of the invention was to develop a process of said type that enables ultrasound to act directly on the article to be cleaned. This object is attained in that the article to be cleaned is led through at least one bore (2) that matches the diameter of the article, along its longitudinal axis, and/or through at least one bore transverse to the longitudinal axis, at the point where the maximum resonance of a special flexural resonator (3) which resonates in air is reached. The flexural resonator (3) resonates at a very high amplitude to generate an intense cavitation field in the bores (2). The flexural resonator (3) is punctually or linearly excited by the ultrasonic sonotrode (1) up to a line of constant amplitude. The cleaning liquid is supplied to the bore (2) so as to fill it completely and is evacuated from the flexural resonator (3) through the bore (2).

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Reinigen von Drähten und Profilen mittels einer durch Ultraschall angeregten Flüssigkeit.The invention relates to a method and a device for cleaning wires and profiles using a through Ultrasonically excited liquid.

Es ist bereits bekannt, Drähte und Profile sowie sonstige Erzeugnisse mittels Ultraschall und Flüssigkeit zu reinigen.It is already known to have wires and profiles as well other products using ultrasound and Clean liquid.

Die bekannten Verfahren, z.B. zur Reinigung von Draht, verwenden Tauchschwinger, die in mit Flüssigkeit gefüllte Behälter eingebracht sind. Die Ultraschallenergie der Tauchschwinger wird in die Flüssigkeit eingestrahlt. In der Flüssigkeit kommt es zur Kavitation, d.h. Flüssigkeit bricht infolge der hohen Energie auseinander, es entstehen Bläschen, deren Inneres mit unter Unterdruck stehendem Gas gefüllt ist. Die Gasbläschen implodieren, dabei wird hohe Energie frei und eine starke Mikroströmung entsteht. Diese Strömung wirkt auf die verschmutzte Oberfläche des zu reinigenden Gutes und entfernt Rückstände wie Fette, Öle oder dgl.The known methods, e.g. for cleaning wire, use submersible transducers that are in with liquid filled containers are introduced. The ultrasonic energy the submersible is in the liquid irradiated. Cavitation occurs in the liquid, i.e. Liquid breaks due to the high energy apart, bubbles form, the inside of which also pressurized gas is filled. The gas bubbles implode, high energy is released and a strong micro flow arises. This current acts on the dirty surface of the to be cleaned Good and removes residues such as fats, oils or the like

Bei den bekannten Einrichtungen bzw. den damit angewendeten Verfahren wird das zu reinigende Gut bzw. der Draht durch die Flüssigkeit eines großen Behälters, in der Regel eines Beckens, gezogen, in welchem eine Schalleistungsdichte von durchschnittlich 1 Watt pro cm2 oder von 15 Watt pro Liter Flüssigkeit besteht, die nur mit hohem Energieaufwand auf die für Reinigungszwecke notwendige Größe gebracht werden kann. Die wirksame Leistung an der Drahtoberfläche liegt weit unter der Gesamtleistung des Ultraschallbeckens. Der Ultraschall wird nicht ausreichend zielgerichtet an der z.B. Drahtoberfläche wirksam, so daß ein hoher Energieeinsatz notwendig wird, um den Reinigungseffekt zu erzielen.In the known devices and the methods used with them, the material to be cleaned or the wire is drawn through the liquid of a large container, usually a basin, in which an average sound power density of 1 watt per cm 2 or 15 watt per There is a liter of liquid which can only be brought to the size required for cleaning purposes with a high energy input. The effective performance on the wire surface is far below the overall performance of the ultrasonic pool. The ultrasound is not sufficiently effective on the wire surface, for example, so that a high level of energy is required to achieve the cleaning effect.

Aus der US 41 00 926 ist weiterhin ein Verfahren bekannt, bei dem eine allgemein bekannte zylindrische Sonotrode verwendet wird, durch die eine Durchführung, in der sich der zu reinigende Draht befindet, geführt wird. Die Reinigungsflüssigkeit wird zerstänbt und in Kammern und in der Durchführung mit dem Draht in Kontakt gebracht. Die Sonotrode kommt mit dem Reinigungsmittel gar nicht in Kontakt. Die Sonotrode muß ein relativ großes Wasservolumen anregen, so daß die Schallenergiekonzentration zu gering ist, um eine ausreichende Reinigungsleistung zu erzielen. Der Ultraschall wirkt nicht direkt genug an der Oberfläche des zu reinigenden Drahtes.A method is also known from US 41 00 926 known in which a generally known cylindrical Sonotrode is used, through which an implementation, in which the wire to be cleaned is guided becomes. The cleaning liquid is crushed and in chambers and in of the feedthrough brought into contact with the wire. The Sonotrode does not come into contact with the cleaning agent Contact. The sonotrode must be a relatively large one Excite water volume so that the Sound energy concentration is too low to be a to achieve sufficient cleaning performance. The Ultrasound does not work directly enough on the surface of the wire to be cleaned.

Aus der DE 40 09 721 A1 ist eine Vorrichtung bekannt, die physikalisch bedingt mit einer sehr kurzen Arbeitslänge bzw. Einwirkstrecke mit Ultraschall auf das zu reinigende Gut nur von einer Seite her einwirkt.A device is known from DE 40 09 721 A1, which is due to physical reasons with a very short Working length or working distance with ultrasound the goods to be cleaned only act from one side.

Aus der AT 350 493 ist- eine weitere Reinigungsanlage mit geringer Effizienz bekannt, die nach dem Längsschwingerprinzip arbeitet. Der zu reinigende Draht wird durch eine Bohrung eines in der Längsachse schwingenden Horns geführt, welches aus vielen Einzelstücken kompliziert und störanfällig zusammengeschraubt ist.Another cleaning system is from AT 350 493 known with low efficiency, based on the longitudinal transducer principle is working. The wire to be cleaned will through a bore of a vibrating in the longitudinal axis Horns, which consists of many individual pieces complicated and prone to failure.

In der DE 196 02 917 wird ein gattungsgemäßes Verfahren beschrieben, nach dem das zu reinigende Erzeugnis durch eine Bohrung einer in der Luft schwingenden speziellen Ultraschall-Sonotrode geführt wird, in die Reinigungsflüssigkeit eingeströmt wird.DE 196 02 917 describes a generic method described, after which the product to be cleaned by a bore of a special one swinging in the air Ultrasonic sonotrode is guided, is poured into the cleaning liquid.

Durch dieses Verfahren wird bereits eine nur geringe Wassermenge direkt in einer Arbeitsbohrung der speziell ausgebildeten Sonotrode durch Ultraschall sehr intensiv angeregt. Es entsteht eine sehr hohe, etwa um zwei Größenordnungen höhere Schall-Leistungsdichte als nach dem bekannten Stand der Technik, mit der eine sehr direkte und effektive Reinigung durch ein intensives Kavitationsfeld erfolgt. This process only makes a small one Amount of water directly in a working hole of the special trained sonotrode by ultrasound very intensive stimulated. There is a very high one, around two Orders of magnitude higher sound power density than after the known prior art, with a very direct and effective cleaning through an intensive Cavitation field takes place.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zum Reinigen von fadenförmigen Erzeugnissen zu entwickeln, mit denen gewährleistet ist, dass der eingebrachte Ultraschall am zu reinigenden Erzeugnis direkt einwirkt.The object of the invention is a method and an apparatus for cleaning thread-like products develop with which it is guaranteed that the introduced Ultrasound acts directly on the product to be cleaned.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen der Ansprüche 1 und 2 sowie der Ansprüche 5 und 6.The solution to this problem results from the characteristics of Claims 1 and 2 and claims 5 and 6.

Das Verfahren nach der Erfindung ist dadurch gekennzeichnet, dass die aus einem Ultraschallwandler und aus einem daran angebrachten Biegeschwinger gebildete Sonotrodenanordnung mit einer hohen Amplitude von ca. 20 bis 250µm punkt- oder linienförmig auf der Linie einer konstanten Amplitude angeregt wird, wobei das zu reinigende Erzeugnis durch mindestens eine in der Längsachse des Biegeschwingers bzw. jeweils an der Stelle eines Schwingungsmaximums quer zur Längsachse des Biegeschwingers angeordnete und an den Querschnitt des zu reinigenden Erzeugnisses angepasste Bohrung geführt wird und die Reinigungsflüssigkeit die mindestens eine Bohrung voll ausfüllt.The method according to the invention is characterized in that that from an ultrasonic transducer and from one attached sonotrode arrangement attached to the bending vibrator with a high amplitude of approx. 20 to 250µm point or line on the line of a constant Amplitude is stimulated, the product to be cleaned by at least one in the longitudinal axis of the bending vibrator or respectively at the Place a maximum of vibration arranged transversely to the longitudinal axis of the bending oscillator and the cross section of the product to be cleaned adapted bore and the cleaning liquid that fully fills at least one hole.

Durch die Verwendung eines speziellen monolithischen Biegeschwingers, durch den das zu reinigende Erzeugnis geführt wird, bei Bedarf auch durch mehrere Bohrungen im Biegeschwinger gleichzeitig, können die für die Reinigung wirksamen Längen vergrößert werden. Es können mit geringerem materiellen Aufwand gleiche Leistungen erzielt werden.By using a special monolithic Bending vibrator through which the product to be cleaned is guided, if necessary, through several holes in the bending vibrator at the same time, they can be used for the Cleaning effective lengths can be increased. It can same services with less material effort be achieved.

Durch die Konzentration des für die Reinigung wirksamen Flüssigkeitsvolumens in einer Arbeitsbohrung eines mit hoher Amplitude von ca. 20 bis 250 µm schwingenden Biegeschwingers wird die eingebrachte Ultraschallleistung auf dieses kleine Volumen konzentriert, so daß mit geringem Energieaufwand ein intensives Kavitationsfeld entsteht, in dem eine hocheffektive Reinigung des durchlaufenden Drahtes gewährleistet ist. Der Ultraschall wirkt innerhalb der Arbeitsbohrung von allen Seiten in geringem Abstand und über eine im Vergleich zur Ultraschall-Sonotrode verhältnismäßig langen Strecke vertikal und intensiv auf die Drahtoberfläche. Es wird eine 20- bis 100-fache Intensität der Schalleistung (bezogen auf die schallabstrahlende Fläche) gegenüber den bekannten Verfahren erreicht, so daß mit einem vergleichbaren Energieaufwand eine wesentlich größere km-Leistung bei zum Beispiel der Drahtreinigung erzielt wird. Es wird außerdem Reinigungsflüssigkeit eingespart, eine kleinere Anlage benötigt und eine höhere Durchlaufgeschwindigkeit des zu reinigenden Gutes erreicht. Die Umweltbelastung wird minimal. Der Einsatz von umweltbelatenden Reinigungsmitteln wird stark reduziert.By concentrating what is effective for cleaning Liquid volume in a working bore with high amplitude of about 20 to 250 µm vibrating The applied ultrasonic power becomes the vibrating bender concentrated on this small volume so that an intensive cavitation field with low energy consumption arises in which a highly effective cleaning of the continuous wire is guaranteed. The ultrasound works within everyone's working hole Pages a short distance apart and compared relatively long to the ultrasonic sonotrode Stretch vertically and intensively on the wire surface. It becomes a 20 to 100 times the intensity of the Sound power (based on the sound emitting Area) compared to the known methods that with a comparable expenditure of energy much greater km performance with, for example, the Wire cleaning is achieved. It will also Cleaning fluid saved, a smaller system needed and a higher throughput speed of the to be cleaned. The environmental impact will minimal. The use of environmental polluting Detergents are greatly reduced.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung sind für die Reinigung eines Drahtes, für die Reinigung mehrerer Drähte, auch im Verbund einer Litze, und auch für die Reinigung von Rundprofilen, Seilen oder dgl. Mit hoher Effektivität anwendbar.The inventive method and the inventive Device are for cleaning a wire for which Cleaning of several wires, also in the connection of a strand, and also for cleaning round profiles, ropes or the like.

Die erste Bohrung 2 steht mit weiteren Bohrungen 4 im Bereich von Schwingungsknoten SK des Biegeschwingers 3 in Verbindung. Diese Bohrungen 4 sind zur Bohrung 2 senkrecht angeordnet und dienen der Zufuhr einer geeigneten Reinigungsflüssigkeit.In the only Fig. 1 is in schematic Sectional view of a bending vibrator 3 shown by an ultrasonic sonotrode 1 to ultrasonic vibrations US is excited. The bending vibrator 3 has a first bore 2 along the longitudinal axis, through which the product to be cleaned, e.g. Wire, to be led. The first hole 2 is with others Bores 4 in the area of vibration node SK des Bending vibrator 3 in connection. These holes 4 are arranged perpendicular to the bore 2 and serve the Supply of a suitable cleaning liquid.

Wenn an die Sonotrode 1 ein für den jeweiligen Anwendungsfall ausreichend dimensionierter Ultraschallprozessor angeschlossen wird, dann gerät die über die Bohrungen 4 eingeströmte Reinigungsflüssigkeit im Biegeschwinger 3 in vertikale Schwingungen, die sich von der Flüssigkeit auf die Oberfläche eines durch die Bohrung 2 konzentrisch durchgeleiteten Drahtes übertragen. Es ist darauf zu achten, daß die Flüssigkeit die Bohrung 2 voll ausfüllt. Durch die Konzentration der eingestrahlten Ultraschalleistung auf das kleine Volumen in der Bohrung 2 und insbesondere auf das Volumen zwischen der Wandung de Bohrung 2 und dem konzentrisch in der Bohrung 2 geführten Draht wird ein sehr intensives Kavitationsfeld gebildet, in dem eine sehr intensive Reinigung der Drahtoberfläche von allen Verschmutzungen erfolgt. Die gelösten Verunreinigungen werden mit der Reinigungsflüssigkeit zu beiden Seiten der Bohrung 2 herausgespült. Die Reinigungsflüssigkeit kann nach einer entsprechenden Aufbereitung dem Prozeß erneut zugeführt werden.If at the sonotrode 1 one for the respective Use case sufficiently dimensioned Ultrasonic processor is connected, then the device Cleaning fluid flowing in through the bores 4 in the bending vibrator 3 into vertical vibrations, which are from the liquid to the surface of one through the Hole 2 concentrically passed wire transfer. Care must be taken that the Liquid completely fills hole 2.
