Definitions
- the invention relates to a knife for splitting, in particular for cutting or sputtering process material using ultrasound energy and a device with at least one such knife.
- cutting devices e.g. Drives provided with rotating cutting discs, which are performed at high clock rates against the products to perform the necessary cuts.
- Such devices are expensive to manufacture, in operation and in maintenance. Due to the rotation of the cutting discs, which have to be reground regularly, there is a massive impact on the material, which dissolves and ejects particles, resulting in contamination of the device.
- the cutting discs and the parameters for their operation are each adapted to the product to be processed, whereby the application is limited or an individual control is provided. For example, if soft bread is to be cut, then high speeds are required so that it is not compressed when applying the cut.
- the rotating cutting discs together with the drive devices take up much space, so that in terms of the means used, including the required premises, low efficiency results.
- the cutting disc must be guided along a path to perform the desired cut in the required length.
- Cutting devices are also known from the prior art, in which a knife is connected via an energy converter with a vibration generator which emits an electrical alternating voltage with a frequency in the ultrasonic range.
- the energy converter which typically includes piezoelectric elements, converts electrical energy into mechanical energy that causes vibration of the blade.
- a vibration device is screwed on the back of a relatively small knife, after which the blade is vibrated in the application of sound waves.
- Another intended for surgical applications knife with a vibrating device is from the W02008148139A1 known. This knife has mechanical vibration amplitudes of 0.0001mm - 1mm.
- the present invention is therefore an object of the invention to provide a knife, with the splitting, in particular the cutting or atomizing, a process material particularly successful in industrial applications using ultrasound energy succeeds.
- a knife is to be provided which has optimum cutting properties for the application of ultrasonic energy for products of virtually any consistency and permits a precise division of the products.
- a knife is to be specified, which can be used for products of any manufacturing process and has optimal properties even for larger and longer products over the entire cutting line.
- the knife should also be advantageous for uniform distribution and mixing of powdery materials.
- About the knife powdered process material is to be delivered evenly to another process material or mixed with this, without any otherwise necessary mixture must be carried out in a liquid.
- an advantageous device is furthermore to be specified.
- the knife which serves for splitting, in particular cutting or uniform atomizing and / or uniform mixing of materials and products using ultrasound energy, comprises a blade with at least a blade wing, which tapers towards the front to a cutting edge and is connected at the back with a blade back, which has opposite larger side surfaces and at free ends smaller end faces.
- a first end piece of at least one arcuate, preferably U-shaped coupling element is welded onto at least one of the side surfaces of the blade back, the second end piece of which has a connection element, preferably a threaded bore, which can be connected to an energy converter supplying the ultrasound energy.
- the application of ultrasonic energy for example, with an operating frequency of 35 kHz gives the knife designed according to the invention surprising properties.
- the ultrasonic energy is coupled across the large side surfaces of the blade back transverse to the at least one cutting direction of the blade in the blade.
- a first end piece of the coupling element preferably runs perpendicular to the blade.
- the action of the ultrasonic energy therefore does not result in a vibratory movement in the cutting direction, as in the case of the known knives.
- elastic waves result within and / or on the surface of the blade, which intensify towards the cutting edge.
- Suitable waves result in a curved or curved configuration of the coupling elements, which are preferably designed U-shaped.
- the two end pieces of the coupling element extend parallel.
- the coupling element is for example a bent rod made of steel with a round profile or a polygonal profile and a length preferably in the range of 5 cm to 30 cm.
- the diameter or edge length of the rod is preferably in the range of 8mm to 16mm.
- Coupling the ultrasonic energy through the curved coupler perpendicularly into the blade results in a favorable pattern of mechanical waves propagating across the blade.
- the coupling of the ultrasonic energy into the blade back according to the invention achieves not only an optimal distribution of the energy within the blade back and a significant reinforcement of the mechanical waves in the area of the blades.
- the optimum distribution of energy also prevents a point overloading of the blade, which could lead to the destruction of the blade.
- Ultrasonic energy can therefore be advantageously introduced into the blade at the operating frequency at which it absorbs maximum power. Due to the rapid distribution of the mechanical waves within the blade back local heating is avoided on the one hand and on the other hand, an optimal effect of the cutting achieved.
- a frequency-modulated signal is supplied to the energy converter connected to the blade, which preferably has a frequency deviation in a range of 1% -10% of the operating frequency and preferably a modulation frequency in the range of 50 Hz-1000 Hz.
- Frequency modulation ensures that the blade is always operated in the optimum working range, regardless of external thermal or mechanical influences.
- the blade back has an increased material thickness typically in the range of 3mm - 10mm.
- the material thickness is adjusted accordingly.
- Knives according to the invention can therefore be used for any desired applications.
- knives can be used in the paper industry to cut paper webs of maximum width.
- knife lengths of 0.5m to 1.5m are used.
- knife lengths of several meters, for example up to 8 meters and more can be used.
- the ultrasonic energy coupled into the blade causes no noticeable vibrations, but recursive material expansions with material displacements in the nanometer range as well as material vibrations, which have an astonishing effect on the processed process material.
- strong transverse waves occur in the area of the cutting edge which run transversely to the cutting direction. Due to the finer waves and vibrations results in a separation effect which is far more intense than the separation effect, which occurs when force or vibration.
- the knife can penetrate into the finest tissue structures and break them. Due to the occurring combination of mechanical waves, such as in Brian M. Lempriere, Ultrasound and Acoustic Waves, Academic Press, London 2002 , an optimum effect is achieved.
- the cutting edge is subjected to longitudinal strains and transverse movements that break up the structures without further damaging them. The machined products not only result in precise cuts, but also in optimal cut surfaces.
- the knife according to the invention can also have a large length, so that a plurality of products transported on a conveyor belt can be processed.
- the knife has a double blade so that one operation can be carried out with each movement of the blade, i.e., during the raising and lowering of the blade. In this way, the passage of the processed products can be doubled.
- the cutting edge of the one or both blade wings is provided with a wave shape or a toothing, which still has a more intensive effect and processes the process material practically in two steps.
- the waves or teeth intervene in the process material and divide this partially, after which the remaining part is separated in a second step.
- the waveform also causes the exposed waves of the blade can swing even more intense, so the effect of the inventive measures is enhanced.
- the upper side of the blade is provided with a wave form which forms troughs or channels running perpendicularly or transversely to the cutting edge. This design of the blade causes a further improved distribution of the ultrasonic energy.
- the provided with a waveform blade can be used particularly advantageous for the transport and the uniform delivery of a powdered process material.
- the process material is distributed evenly over the top of the blade and is transported along the grooves to the cutting edge, where it is atomized and lowered as a uniform fog. If two knives according to the invention are arranged one below the other or next to one another, the powder mist of each process material mixes in an ideal manner and form a virtually homogeneous mix with a degree of mixing which otherwise can only be achieved after long stirring in a liquid.
- each powdered process material is dispensed to the associated knife with a certain dosage, so an optimally mixed mix can be achieved with optional specified product proportions.
- the distance of the troughs or grooves on the working surface of the blade is preferably selected as a function of the wavelength of the ultrasonic waves.
- distances of the grooves in the range of 5mm - 15mm and an amplitude of the waves of the waveform in the range of 0.5mm to 4mm are chosen.
- the top of the blade serving to transport the process material preferably forms a plane.
- the underside of the blade has, in the region of the blade back, a zone running parallel to the upper side and, in the region of the first and / or second blade wing, a plane inclined towards the associated cutting edge.
- the knife is connected via the at least one coupling element and in each case one energy converter mounted thereon to a generator, which is preferably controlled by a programmable Control unit, an electrical AC voltage in the frequency range of the ultrasound, preferably in the range between 30 kHz and 40 kHz, outputs.
- a generator which is preferably controlled by a programmable Control unit, an electrical AC voltage in the frequency range of the ultrasound, preferably in the range between 30 kHz and 40 kHz, outputs.

- the tops 1010, 101U of the blade wings 101, 102 form a flat surface with the top 1030 of the blade spine 103 in this preferred embodiment, while the bottoms 101U, 102U of the blade wings 101, 102 with respect to the bottom 103U of the blade spine 103 to the blades 1011, 1021 are inclined towards.
- a respective U-shaped coupling element 181, 182 is welded to a first end piece 1811, which is aligned perpendicular to the bottom 103U, the blade back 103 and thus perpendicular to the cutting direction of the blade 1A.
- the coupling elements 181, 182 welded onto the underside 10U of the blade 10 run outward in an opposite direction with an arcuate intermediate piece 1813 along the axis of the blade back 103.

Durch die Rotation der Schneidscheiben, die regelmässig neu geschliffen werden müssen, erfolgt eine massive Einwirkung auf das Material, welche Partikel herauslöst und weggeschleudert, wodurch eine Verschmutzung der Vorrichtung resultiert.In many industrial applications, especially in the food industry, products of the intended dimensions must be provided. For example, portions of meat, sausage or cheese should be provided as individual pieces or divided into slices. For this purpose, cutting devices, e.g. Drives provided with rotating cutting discs, which are performed at high clock rates against the products to perform the necessary cuts. Such devices are expensive to manufacture, in operation and in maintenance. Due to the rotation of the cutting discs, which have to be reground regularly, there is a massive impact on the material, which dissolves and ejects particles, resulting in contamination of the device.
Weiterhin sind die Schneidscheiben und die Parameter für deren Betrieb jeweils an das zu verarbeitende Produkt anzupassen, wodurch der Einsatzbereich beschränkt ist oder eine individuelle Ansteuerung vorzusehen ist. Sofern beispielsweise weiches Brot geschnitten werden soll, so sind hohe Drehzahlen erforderlich, damit dieses bei der Applikation des Schnittes nicht zusammengedrückt wird. Zudem nehmen die rotierenden Schneidscheiben zusammen mit den Antriebsvorrichtungen viel Raum in Anspruch, so dass hinsichtlich der eingesetzten Mittel, einschliesslich der benötigten Räumlichkeiten, eine geringe Effizienz resultiert. Ferner resultieren bei Produkten mit grossen Abmessungen besondere Anforderungen an die Schneidvorrichtung. Gegebenenfalls muss die Schneidscheibe entlang einer Bahn geführt werden, um den gewünschten Schnitt in der erforderlichen Länge auszuführen.Furthermore, the cutting discs and the parameters for their operation are each adapted to the product to be processed, whereby the application is limited or an individual control is provided. For example, if soft bread is to be cut, then high speeds are required so that it is not compressed when applying the cut. In addition, the rotating cutting discs together with the drive devices take up much space, so that in terms of the means used, including the required premises, low efficiency results. Furthermore, for products with large dimensions special demands on the Cutter. If necessary, the cutting disc must be guided along a path to perform the desired cut in the required length.
Aus dem Stand der Technik sind ferner Schneidvorrichtungen bekannt, bei denen ein Messer über einen Energiewandler mit einem Schwingungserzeuger verbunden ist, der eine elektrische Wechselspannung mit einer Frequenz im Ultraschallbereich abgibt. Der Energiewandler, der typischerweise piezoelektrische Elemente aufweist, wandelt die elektrische Energie in mechanische Energie um, die eine Vibration des Messers bewirkt.Cutting devices are also known from the prior art, in which a knife is connected via an energy converter with a vibration generator which emits an electrical alternating voltage with a frequency in the ultrasonic range. The energy converter, which typically includes piezoelectric elements, converts electrical energy into mechanical energy that causes vibration of the blade.

Ein weiteres für chirurgische Anwendungen vorgesehenes Messer mit einer Vibrationsvorrichtung ist aus der
Für grössere Messer sind entsprechend grössere und aufwändig gestaltete Vibrationsvorrichtungen erforderlich.Larger knives require correspondingly larger and more elaborate vibration devices.
Weiterhin besteht bei industriellen Prozessen, zum Beispiel in der Pharmaindustrie oder der Nahrungsmittelindustrie, oft die Notwendigkeit, Materialien in Pulverform gleichmässig verteilt an einen Abnehmer abzugeben. Beispielsweise soll das Material einem festen Produkt oder einem Flüssiggut zugeführt werden, wobei eine Klumpenbildung zu vermeiden ist. Weiterhin sind oft verschiedene pulverförmige Substanzen gleichmässig zu mischen, was durch den Einsatz von Mischwerken und Rührwerken oft nur mit grossem Aufwand und langer Bearbeitungszeit gelingt.Furthermore, in industrial processes, for example in the pharmaceutical industry or the food industry, there is often the need to dispense materials in powder form evenly distributed to a customer. For example, the material should be supplied to a solid product or a liquid, wherein a lump formation is to be avoided. Furthermore, often different powdery substances are to be mixed evenly, which often succeeds by the use of mixing plants and agitators only with great effort and long processing time.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Messer zu schaffen, mit dem das Aufteilen, insbesondere das Schneiden oder Zerstäuben, eines Prozessguts insbesondere in industriellen Anwendungen unter Anwendung von Ultraschallenergie besonders vorteilhaft gelingt.The present invention is therefore an object of the invention to provide a knife, with the splitting, in particular the cutting or atomizing, a process material particularly successful in industrial applications using ultrasound energy succeeds.
Insbesondere ist ein Messer anzugeben, welches bei der Anwendung von Ultraschallenergie bei Produkten nahezu beliebiger Konsistenz optimale Schneideigenschaften aufweist und eine präzise Aufteilung der Produkte erlaubt.In particular, a knife is to be provided which has optimum cutting properties for the application of ultrasonic energy for products of virtually any consistency and permits a precise division of the products.
Weiterhin ist ein Messer anzugeben, welches für Produkte beliebiger Herstellungsprozesse einsetzbar ist und auch bei grösseren und längeren Produkten über die gesamte Schnittlinie optimale Eigenschaften aufweist.Furthermore, a knife is to be specified, which can be used for products of any manufacturing process and has optimal properties even for larger and longer products over the entire cutting line.
Weiterhin soll bei der Verwendung des Messers in einer erfindungsgemässen Vorrichtung ein deutlich höherer Durchsatz an bearbeiteten Produkten realisierbar sein.Furthermore, when using the knife in a device according to the invention, a significantly higher throughput of processed products should be achievable.
Das Messer soll ferner auch für die gleichmässig Aufteilung und Mischung von pulverförmigen Materialien vorteilhaft einsetzbar sein. Über das Messer soll pulverförmiges Prozessgut gleichmässig an ein weiteres Prozessgut abgegeben oder mit diesem gemischt werden können, ohne dass eine ansonsten gegebenenfalls erforderliche Mischung in einer Flüssigkeit durchgeführt werden muss.The knife should also be advantageous for uniform distribution and mixing of powdery materials. About the knife powdered process material is to be delivered evenly to another process material or mixed with this, without any otherwise necessary mixture must be carried out in a liquid.
Für den Betrieb eines oder mehrerer erfindungsgemässer Messer ist ferner eine vorteilhafte Vorrichtung anzugeben.For the operation of one or more knives according to the invention, an advantageous device is furthermore to be specified.
Diese Aufgabe wird mit einem Messer und einer Vorrichtung gelöst, welche die in Anspruch 1 bzw. Anspruch 9 angegebenen Merkmale aufweisen. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.This object is achieved with a knife and a device which have the features specified in claim 1 or
Das Messer, das dem Aufteilen, insbesondere dem Schneiden oder dem gleichmässigen Zerstäuben und/oder gleichmässigen Mischen von Materialien und Produkten unter Anwendung von Ultraschallenergie dient, umfasst eine Klinge mit wenigstens einem Klingenflügel, welcher sich frontseitig zu einer Schneide hin verjüngt und rückseitig mit einem Klingenrücken verbunden ist, der einander gegenüberliegende grössere Seitenflächen und an frei liegenden Enden kleinere Stirnflächen aufweist.The knife, which serves for splitting, in particular cutting or uniform atomizing and / or uniform mixing of materials and products using ultrasound energy, comprises a blade with at least a blade wing, which tapers towards the front to a cutting edge and is connected at the back with a blade back, which has opposite larger side surfaces and at free ends smaller end faces.
Erfindungsgemäss ist wenigstens auf einer der Seitenflächen des Klingenrückens ein erstes Endstück wenigstens eines in einem Bogen verlaufenden, vorzugsweise U-förmigen Kopplungselements angeschweisst, dessen zweites Endstück ein Verbindungselement, vorzugsweise eine Gewindebohrung, aufweist, welches mit einem der Zufuhr von Ultraschallenergie dienenden Energiewandler verbindbar ist.According to the invention, a first end piece of at least one arcuate, preferably U-shaped coupling element is welded onto at least one of the side surfaces of the blade back, the second end piece of which has a connection element, preferably a threaded bore, which can be connected to an energy converter supplying the ultrasound energy.
Die Anwendung von Ultraschallenergie beispielsweise mit einer Arbeitsfrequenz von 35 kHz verleiht dem erfindungsgemäss ausgestalteten Messer überraschende Eigenschaften. Die Ultraschallenergie wird über die grossen Seitenflächen des Klingenrückens quer zu der wenigstens einen Schnittrichtung des Messers in die Klinge eingekoppelt. Ein erstes Endstück des Kopplungselements verläuft dabei vorzugsweise senkrecht zur Klinge. Bei der Einwirkung der Ultraschallenergie resultiert daher nicht wie bei den bekannten Messern eine Vibrationsbewegung in Schneiderichtung. Stattdessen resultieren elastische Wellen innerhalb und/oder auf der Oberfläche der Klinge, die sich zur Schneide hin intensivieren. Geeignete Wellen resultieren bei gekrümmter oder gebogener Ausgestaltung der Kopplungselemente, die vorzugsweise U-förmig ausgestaltet sind.The application of ultrasonic energy, for example, with an operating frequency of 35 kHz gives the knife designed according to the invention surprising properties. The ultrasonic energy is coupled across the large side surfaces of the blade back transverse to the at least one cutting direction of the blade in the blade. A first end piece of the coupling element preferably runs perpendicular to the blade. The action of the ultrasonic energy therefore does not result in a vibratory movement in the cutting direction, as in the case of the known knives. Instead, elastic waves result within and / or on the surface of the blade, which intensify towards the cutting edge. Suitable waves result in a curved or curved configuration of the coupling elements, which are preferably designed U-shaped.
Dabei ist es vorteilhaft, ein kürzeres erstes Endstück des Kopplungselements auf einer Klingenseite zu montieren und ein längeres zweites Endstück des Kopplungselements mittels eines Bogens um den Klingenrücken herum oder durch eine Öffnung im Klingenrücken hindurch auf die andere Seite der Klinge zu führen. In vorzugsweisen Ausgestaltungen verlaufen die beiden Endstücke des Kopplungselements parallel.It is advantageous to mount a shorter first end of the coupling element on one side of the blade and to guide a longer second end of the coupling element by means of a bow around the blade back or through an opening in the blade back on the other side of the blade. In preferred embodiments, the two end pieces of the coupling element extend parallel.
Das Kopplungselement ist beispielsweise ein gebogener Stab aus Stahl mit einem Rundprofil oder einem Mehrkantprofil und einer Länge vorzugsweise im Bereich von 5 cm bis 30 cm. Der Durchmesser oder die Kantenlänge des Stabs liegt vorzugsweise im Bereich von 8mm bis 16mm.The coupling element is for example a bent rod made of steel with a round profile or a polygonal profile and a length preferably in the range of 5 cm to 30 cm. The diameter or edge length of the rod is preferably in the range of 8mm to 16mm.
Durch die Einkopplung der Ultraschallenergie über das gebogene Kopplungsstück senkrecht in die Klinge resultiert ein vorteilhaftes Muster mechanischer Wellen, die sich über die Klinge ausbreiten. Durch die erfindungsgemässe Einkopplung der Ultraschallenergie in den Klingenrücken werden nicht nur eine optimale Verteilung der Energie innerhalb des Klingenrückens und eine signifikante Verstärkung der mechanischen Wellen im Bereich der Schneiden erzielt. Gleichzeitig wird durch die optimale Verteilung der Energie auch eine punktuelle Überlastung der Klinge vermieden, welche zu einer Zerstörung des Messers führen könnte. Ultraschallenergie kann daher vorteilhaft bei der derjenigen Arbeitsfrequenz in die Klinge eingeführt werden, bei der diese eine maximale Leistung aufnimmt. Aufgrund der raschen Verteilung der mechanischen Wellen innerhalb des Klingenrückens wird einerseits eine lokale Erwärmung vermieden und andererseits eine optimale Wirkung der Schneiden erzielt.Coupling the ultrasonic energy through the curved coupler perpendicularly into the blade results in a favorable pattern of mechanical waves propagating across the blade. The coupling of the ultrasonic energy into the blade back according to the invention achieves not only an optimal distribution of the energy within the blade back and a significant reinforcement of the mechanical waves in the area of the blades. At the same time, the optimum distribution of energy also prevents a point overloading of the blade, which could lead to the destruction of the blade. Ultrasonic energy can therefore be advantageously introduced into the blade at the operating frequency at which it absorbs maximum power. Due to the rapid distribution of the mechanical waves within the blade back local heating is avoided on the one hand and on the other hand, an optimal effect of the cutting achieved.
Vorzugsweise wird dem mit der Klinge verbundenen Energiewandler ein frequenzmoduliertes Signal zugeführt, welches vorzugsweise einen Frequenzhub in einem Bereich von 1% - 10% der Arbeitsfrequenz und vorzugsweise eine Modulationsfrequenz im Bereich von 50Hz - 1000Hz aufweist. Durch die Frequenzmodulation wird gewährleistet, dass das Messer unabhängig von äusseren thermischen oder mechanischen Einwirkungen stets im optimalen Arbeitsbereich betrieben wird.Preferably, a frequency-modulated signal is supplied to the energy converter connected to the blade, which preferably has a frequency deviation in a range of 1% -10% of the operating frequency and preferably a modulation frequency in the range of 50 Hz-1000 Hz. Frequency modulation ensures that the blade is always operated in the optimum working range, regardless of external thermal or mechanical influences.
Der Klingenrücken weist eine erhöhte Materialdicke typischerweise im Bereich von 3mm - 10mm auf. Für längere oder kürzere Messer oder bei der Zufuhr erhöhter Leistung wird die Materialdicke entsprechend angepasst. Besonders vorteilhaft ist, dass die vorteilhafte Wirkung auch bei Messern praktisch beliebiger Länge erzielt werden kann, bei denen Ultraschallenergie vorzugsweise in gleichmässigen Abständen von zum Beispiel 30 cm - 90cm über Kopplungselemente zugeführt wird. Erfindungsgemässe Messer können daher für beliebige Anwendungen eingesetzt werden. Beispielsweise können Messer in der Papierindustrie eingesetzt werden, um Papierbahnen maximaler Breite zu schneiden. In der Mehrheit der Anwendungen, insbesondere in der Nahrungsmittelindustrie, werden Messerlängen von 0,5m bis 1,5m eingesetzt. Es können jedoch Messerlängen von mehreren Metern beispielsweise bis zu 8 m und mehr eingesetzt werden.The blade back has an increased material thickness typically in the range of 3mm - 10mm. For longer or shorter knives or when supplying increased power, the material thickness is adjusted accordingly. Especially advantageous is that the advantageous effect can be achieved even with knives virtually any length, in which ultrasonic energy is preferably supplied at uniform intervals of for example 30 cm - 90cm via coupling elements. Knives according to the invention can therefore be used for any desired applications. For example, knives can be used in the paper industry to cut paper webs of maximum width. In the majority of applications, especially in the food industry, knife lengths of 0.5m to 1.5m are used. However, knife lengths of several meters, for example up to 8 meters and more, can be used.
Die in die Klinge eingekoppelte Ultraschallenergie bewirkt keine spürbaren Vibrationen, sondern rekursive Materialdehnungen mit Materialverschiebungen im Nanometerbereich sowie Materialschwingungen, welche eine erstaunliche Wirkung beim bearbeiteten Prozessgut zur Folge haben. Nebst Longitudinalwellen treten im Bereich der Schneide kräftige Transversalwellen auf, die quer zur Schneiderichtung verlaufen. Durch die feineren Wellen und Schwingungen resultiert eine Trennwirkung die weit intensiver ist als die Trennwirkung, die bei Krafteinwirkung oder Einwirkung von Vibrationen eintritt. Das Messer kann in feinste Gewebestrukturen eindringen und diese auftrennen. Durch die auftretende Kombination mechanischer Wellen, wie sie z.B. in
Durch mechanische Longitudinalwellen und Transversalwellen wird weiches oder hartes Prozessgut im Bereich der Klinge aufgetrennt, ohne dass eine Krafteinwirkung aufgewendet werden muss. Dies hat zur Folge, dass selbst sehr weiches Prozessgut bei der Bearbeitung keinen Deformationen unterworfen ist und daher präzise geschnitten werden kann. Beispielsweise kann weiches Brot in Scheiben minimaler Dicke geschnitten werden. Durch die Vermeidung einer Krafteinwirkung wird die Schneide der Klinge zudem geschont, so dass diese erst nach relativ langer Betriebszeit wieder geschärft werden muss.Mechanical longitudinal waves and transverse waves cause soft or hard process material in the area of the blade separated, without a force must be applied. As a result, even very soft process material is not subject to deformation during machining and can therefore be precisely cut. For example, soft bread can be cut into slices of minimal thickness. By avoiding a force, the cutting edge of the blade is also protected, so that it must be sharpened again after a relatively long period of operation.
Das erfindungsgemässe Messer kann auch eine grosse Länge aufweisen, so dass mehrere auf einem Förderband transportierte Produkte bearbeitet werden können. In einer besonders bevorzugten Ausgestaltung weist das Messer eine Doppelklinge auf, so dass mit jeder Bewegung der Klinge, d.h., beim Anheben und beim Absenken der Klinge, ein Arbeitsgang ausgeführt werden kann. Auf diese Weise kann der Durchlauf der bearbeiteten Produkte verdoppelt werden.The knife according to the invention can also have a large length, so that a plurality of products transported on a conveyor belt can be processed. In a particularly preferred embodiment, the knife has a double blade so that one operation can be carried out with each movement of the blade, i.e., during the raising and lowering of the blade. In this way, the passage of the processed products can be doubled.
In bevorzugten Ausgestaltungen wird die Schneide des einen oder beider Klingenflügel mit einer Wellenform oder einer Verzahnung versehen, die noch eine intensivere Wirkung aufweist und das Prozessgut praktisch in zwei Schritten bearbeitet. Im ersten Schritt greifen die Wellen oder Zähne in das Prozessgut ein und teilen dies partiell auf, wonach in einem zweiten Schritt der verbleibende Teil aufgetrennt wird. Die Wellenform bewirkt ferner, dass die freiliegenden Wellen der Schneide noch intensiver schwingen können, weshalb die Wirkung der erfindungsgemässen Massnahmen noch verstärkt wird.In preferred embodiments, the cutting edge of the one or both blade wings is provided with a wave shape or a toothing, which still has a more intensive effect and processes the process material practically in two steps. In the first step, the waves or teeth intervene in the process material and divide this partially, after which the remaining part is separated in a second step. The waveform also causes the exposed waves of the blade can swing even more intense, so the effect of the inventive measures is enhanced.
In besonders bevorzugten Ausgestaltungen wird die Oberseite der Klinge, gegebenenfalls nur eine der Oberseiten der Klingenflügel, mit einer Wellenform versehen, die senkrecht oder quer zur Schneide verlaufende Wellentäler oder Rinnen bildet. Diese Ausgestaltung der Klinge bewirkt eine weiter verbesserte Verteilung der Ultraschallenergie.In particularly preferred embodiments, the upper side of the blade, optionally only one of the upper sides of the blade wings, is provided with a wave form which forms troughs or channels running perpendicularly or transversely to the cutting edge. This design of the blade causes a further improved distribution of the ultrasonic energy.
Die mit einer Wellenform versehene Klinge kann besonders vorteilhaft auch für den Transport und die gleichmässige Abgabe eines pulverförmigen Prozessguts verwendet werden. Bei dieser Ausgestaltung der Klinge verteilt sich das Prozessgut gleichmässig über die Oberseite der Klinge und wird entlang der Rillen zur Schneide befördert, wo es zerstäubt wird und sich als gleichmässiger Nebel absenkt. Sofern zwei erfindungsgemässe Messer untereinander oder nebeneinander angeordnet sind, so vermischen sich die Pulvernebel jedes Prozessguts in idealer Weise und bilden ein praktisch homogenes Mischgut mit einem Durchmischungsgrad, der ansonsten nur nach langem Rühren in einer Flüssigkeit erzielt werden kann.The provided with a waveform blade can be used particularly advantageous for the transport and the uniform delivery of a powdered process material. In this embodiment of the blade, the process material is distributed evenly over the top of the blade and is transported along the grooves to the cutting edge, where it is atomized and lowered as a uniform fog. If two knives according to the invention are arranged one below the other or next to one another, the powder mist of each process material mixes in an ideal manner and form a virtually homogeneous mix with a degree of mixing which otherwise can only be achieved after long stirring in a liquid.
Sofern jedes pulverförmige Prozessgut mit einer bestimmten Dosierung an das zugehörige Messer abgegeben wird, so kann ein optimal durchmischtes Mischgut mit wahlweise festgelegten Produktanteilen erzielt werden.If each powdered process material is dispensed to the associated knife with a certain dosage, so an optimally mixed mix can be achieved with optional specified product proportions.
Der Abstand der Wellentäler oder Rinnen auf der Arbeitsoberfläche der Klinge wird vorzugsweise in Abhängigkeit der Wellenlänge der Ultraschallwellen gewählt. Vorzugsweise werden Abstände der Rinnen im Bereich von 5mm - 15mm und eine Amplitude der Wellen der Wellenform im Bereich von 0,5mm bis 4mm gewählt.The distance of the troughs or grooves on the working surface of the blade is preferably selected as a function of the wavelength of the ultrasonic waves. Preferably, distances of the grooves in the range of 5mm - 15mm and an amplitude of the waves of the waveform in the range of 0.5mm to 4mm are chosen.
Die dem Transport des Prozessguts dienende Oberseite der Klinge bildet vorzugsweise eine Ebene. Die Unterseite der Klinge weist im Bereich des Klingenrückens eine parallel zur Oberseite verlaufende Zone und im Bereich des ersten und/oder zweiten Klingenflügels eine gegen die zugehörige Schneide geneigte Ebene auf.The top of the blade serving to transport the process material preferably forms a plane. The underside of the blade has, in the region of the blade back, a zone running parallel to the upper side and, in the region of the first and / or second blade wing, a plane inclined towards the associated cutting edge.
Bei erfindungsgemässen Vorrichtungen ist das Messer über das wenigstens eine Kopplungselement und je einen daran montierten Energiewandler mit einem Generator verbunden, welcher, vorzugsweise gesteuert durch eine programmierbare Steuereinheit, eine elektrische Wechselspannung im Frequenzbereich des Ultraschalls, vorzugsweise im Bereich zwischen 30 kHz und 40 kHz, abgibt.In devices according to the invention, the knife is connected via the at least one coupling element and in each case one energy converter mounted thereon to a generator, which is preferably controlled by a programmable Control unit, an electrical AC voltage in the frequency range of the ultrasound, preferably in the range between 30 kHz and 40 kHz, outputs.

An beiden Enden der Unterseite 103U des Klingenrückens 103 ist je ein U-förmig ausgebildetes Kopplungselement 181, 182 mit einem ersten Endstück 1811 angeschweisst, das senkrecht zur Unterseite 103U, des Klingenrückens 103 und somit senkrecht zur Schnittrichtung des Messers 1A ausgerichtet ist.

Es hat sich herausgestellt, dass der Messer 1B nicht nur für das Schneiden, sondern auch hervorragend für die Zerstäubung eines pulverförmigen Prozessguts geeignet ist. Pulverförmiges Prozessgut, welches über die geneigte Klinge 10 transportiert wird, wird an den Schneiden 1011, 1021 zerstäubt bzw. in kleinste Partikel aufgeteilt und von den seitlich schwingenden Wellensegmenten weggeschleudert.It has been found that the
Damit eine gleichmässige Aufteilung des pulverförmigen Prozessguts erzielt wird, wird sichergestellt, dass sich die Ultraschallenergie über die Klinge 10 gleichmässig verteilt.
