Description
Die Erfindung betrifft eine Vorrichtung zum Bearbeiten einer Materialbahn mit einer eine Sonotrode aufweisenden Ultraschalleinheit und einem Gegenwerkzeug, wobei die Materialbahn durch einen Spalt zwischen der Sonotrode und dem Gegenwerkzeug geführt und von der Sonotrode bearbeitet wird, wobei die Sonotrode oder das Gegenwerkzeug über einen elektrischen Antrieb bezüglich dem Gegenwerkzeug oder der Sonotrode verstellbar ist, und mit einem Sensor, der mit einer Steuer- oder Regeleinheit verbunden ist, die abhängig vom Signal des Sensors eine Änderung des Abstands der Sonotrode zum Gegenwerkzeug bewirkt.The The invention relates to a device for processing a material web with a sonotrode having an ultrasonic unit and a Counter tool, the web through a gap between led to the sonotrode and the counter tool and edited by the sonotrode is, with the sonotrode or the counter tool on a electric drive with respect to the counter tool or sonotrode is adjustable, and with a Sensor connected to a control unit which dependent from the signal of the sensor a change causes the distance of the sonotrode to the counter tool.
Es ist bekannt, dass mittels Ultraschall-Sonotroden Materialbahnen verbunden, geschnitten, perforiert, gestanzt, geprägt, wärmebehandelt oder auf ähnliche Weise bearbeitet werden. Entscheidend ist bei den Sonotroden, dass deren Spitze mit einer exakt vorgegebenen Kraft auf die Materialbahn drückt oder presst, so dass die zum Bearbeiten erforderliche Energie in die Materialbahn eingebracht werden kann. Aufgrund der bei der Bearbeitung entstehenden Wärme ändert sich die Länge des Bearbeitungswerkzeugs, zum Beispiel der Sonotrode, was zu einer Änderung der Spalthöhe führen kann. Ein zu enger Spalt führt jedoch in der Regel zu einer Verschlechterung der Materialbearbeitung und kann unter Umständen in einer Beschädigung der Materialbahn oder der Werkzeuge resultieren, da die Anpresskraft zu hoch ist und somit zu viel Energie in die Materialbahn eingebracht wird. Ein zu weiter Spalt ergibt eine nicht akzeptable Schweiß- oder Schneidqualität, da die Anpresskraft zu gering ist. Es wird daher angestrebt, die Anpresskraft auf einen gewünschten Wert möglichst konstant zu halten.It It is known that by ultrasound sonotrodes material webs connected, cut, perforated, punched, embossed, heat-treated or similar Way to be edited. The decisive factor in the sonotrodes is that whose tip presses with a precisely predetermined force on the material web or presses so that the energy required for editing in the Material web can be introduced. Because of when editing resulting heat changes the length of the machining tool, for example, the sonotrode, resulting in a change the gap height to lead can. A too narrow gap leads however, usually to a deterioration of material processing and may possibly in damage the web or the tools result because the contact pressure is too high and thus introduced too much energy in the web becomes. Too much gap results in an unacceptable weld or Cutting quality, because the contact pressure is too low. It is therefore desirable, the Contact pressure on a desired Value as possible to keep constant.
Auch eine Änderung der Bearbeitungsgeschwindigkeit, also der Durchlaufgeschwindigkeit der Materialbahn durch den Arbeitsspalt, macht eine Änderung der Anpresskraft erforderlich, da zum Beispiel bei einer Geschwindigkeitserhöhung in kürzerer Zeit die erforderliche Schweißenergie in die Materialbahn eingebracht werden muss. Also muss in diesem Fall die Anpresskraft erhöht werden.Also a change the processing speed, ie the throughput speed the material web through the working gap makes a change the contact force required, for example, at a speed increase in shorter Time the required welding energy must be introduced into the web. So in this Case increases the contact pressure become.

Aus
der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Ultraschallbearbeitungsvorrichtung bereitzustellen, mit welcher die Anpresskraft relativ einfach erfasst und eingestellt, insbesondere geregelt werden kann.Of the The invention is therefore based on the object, an ultrasonic processing device to provide, with which the contact force relatively easily detected and adjusted, in particular, can be regulated.
Diese Aufgabe wird mit einer Bearbeitungsvorrichtung der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass der Sensor mit dem Eingang oder dem Ausgang des Antriebs verknüpft ist, um die Zustandsdaten des Antriebs an dessen Eingang oder an dessen Ausgang zu überwachen.These Task is with a processing device of the aforementioned Type according to the invention thereby solved, that the sensor is linked to the input or the output of the drive to the status data of the drive at its input or at its Monitor output.
Der wesentliche Unterschied zum Stand der Technik besteht darin, dass nicht mehr die Kraft ermittelt wird, mit welcher die Sonotrode die Materialbahn auf das Gegenwerkzeug presst. Ändert sich die Anpresskraft, dann ändern sich die Zustandsdaten des Antriebs, welcher die Sonotrode oder das Gegenwerkzeug in Richtung auf das jeweils andere Bauteil zustellt, indem der Antrieb mehr oder weniger Energie für die Zustellung benötigt, ein größeres oder kleineres Drehmoment an dessen Abtrieb aufbringen muss oder der Abtrieb mehr oder weniger weit ausgefahren werden muss. Dabei werden nunmehr erfindungsgemäß diese Zustandsdaten entweder am Eingang oder am Ausgang des Antriebs überwacht. Der Sensor ist also nicht mehr, wie beim Stand der Technik, der Sonotrode sondern dem Antrieb zugeordnet.The essential difference from the prior art is that the force with which the sonotrode presses the material web onto the counter tool is no longer determined. If the contact force changes, then the status data of the drive, which delivers the sonotrode or the counter-tool in the direction of the respective other component, in that the drive requires more or less energy for the delivery, has to apply a greater or lesser torque to its output or the output must be extended more or less far. In the process, according to the invention, these status data are now monitored either at the input or at the output of the drive. The sensor is no longer, as in the state of Technique, the sonotrode but the drive assigned.
Bei einem Ausführungsbeispiel erfasst der Sensor die Energieaufnahme des Antriebs. Dies bedeutet, dass zum Beispiel bei einer Verringerung der Anpresskraft die Sonotrode beziehungsweise das Gegenwerkzeug weniger stark angepresst werden muss, so dass die Energieaufnahme des Antriebs geringer ist. Dies kann direkt vom Sensor erfasst werden, indem dieser zum Beispiel ein Stromaufnahmesensor ist. Soll die Anpresskraft verringert werden, dann wird über die Steuer- und Regeleinrichtung die Stromaufnahme so weit verringert, bis die gewünschte Anpresskraft und dadurch die gewünschte Leistungs- und Energieabgabe erreicht ist. Dabei ist in einem geeigneten Speicher die Beziehung zwischen Anpresskraft und Stromaufnahme in digitaler oder analoger Form abgelegt. Andererseits kann durch eine Veränderung der Stromaufnahme festgestellt werden, dass sich die Anpresskraft ändert, so dass durch geeignete Ansteuerung des Antriebs die Anpresskraft wieder auf den gewünschten Wert zurückgeführt werden kann.at an embodiment the sensor detects the energy consumption of the drive. This means, that, for example, with a reduction in the contact pressure, the sonotrode or the counter tool needs to be pressed less strongly, so that the energy consumption of the drive is lower. This can be detected directly by the sensor by this example Power consumption sensor is. If the contact pressure is reduced, then will over the control device reduces the power consumption so far until the desired Contact pressure and thus the desired Power and energy tax is reached. The relationship is in a suitable memory between contact pressure and current consumption in digital or analogue Filed form. On the other hand, it can be determined by changing the current consumption, that the contact force changes, so that by suitable control of the drive, the contact pressure back to the desired Value be traced back can.
Bei einem anderen Ausführungsbeispiel wird am Ausgang des Antriebs die Momentabgabe erfasst. Hierfür ist zum Beispiel ein Drehmomentsensor vorgesehen, der ein hochpräzises aber dennoch preiswertes Bauteil ist. Auch hier stellt das vom Antrieb aufgebrachte Drehmoment eine direkte Beziehung zur Anpresskraft dar. Drehmomente können zum Beispiel mit Hallsensoren relativ einfach ermittelt werden.at another embodiment the torque output is recorded at the output of the drive. This is for Example, a torque sensor provided, which is a high-precision but still cheap component is. Again, this is the drive Applied torque a direct relationship to the contact force Torques can for Example with Hall sensors can be determined relatively easily.
Eine andere Ausführungsform sieht vor, dass die Verlagerung eines Abtriebselements des Antriebs, insbesondere die Verschiebung des Abtriebselements bei einem Linearmotor, erfasst wird. Hierfür ist zum Beispiel ein Wegsensor vorgesehen.A other embodiment provides that the displacement of an output element of the drive, in particular the displacement of the output element in a linear motor, is detected. Therefor For example, a displacement sensor is provided.
Wie bereits erwähnt, wird bevorzugt ein Elektromotor, insbesondere ein Drehmotor, Schrittmotor, Servomotor oder Linearmotor, als Antrieb verwendet. Dabei kann die Sonotrode oder das Gegenwerkzeug verlagert werden. Falls erforderlich, können auch beide Bauteile, das heißt Sonotrode und Gegenwerkzeug, verlagert werden.As already mentioned, is preferably an electric motor, in particular a rotary motor, stepper motor, servo motor or linear motor, used as a drive. In this case, the sonotrode or the counter tool are relocated. If necessary, can also both components, that is Sonotrode and counter tool, to be relocated.
Gemäß einer bevorzugten Variante der Erfindung wirkt das Abtriebselement des Antriebs direkt oder indirekt auf die Sonotrode, das heißt mit oder ohne Zwischenschaltung eines Getriebes. Ferner können die Sonotrode oder das Gegenwerkzeug einerseits und der Antrieb andererseits parallel zueinander, d. h. mit parallelen Achsen oder in einer gemeinsamen Achse, d. h. übereinander liegen. Diese Ausgestaltung besitzt den wesentlichen Vorteil, dass die gesamte Vorrichtung sehr schlank ist, da die einzelnen Bauteile übereinander angeordnet sind.According to one preferred variant of the invention, the output element of the acts Drive directly or indirectly to the sonotrode, ie with or without Interposition of a gearbox. Furthermore, the sonotrode or the Counter tool on the one hand and the drive on the other hand parallel to each other, d. H. with parallel axes or in a common axis, d. H. one above the other lie. This embodiment has the significant advantage that the entire device is very slim, as the individual components on top of each other are arranged.
Bei einer anderen Ausführungsform schließen die Achsen der Sonotrode und des Gegenwerkzeugs einerseits und des Antriebs andererseits einen Winkel zwischen 0° und 180° ein, und es ist ein Getriebe zwischengeschaltet. Diese Ausführungsform besitzt den Vorteil, dass die Vorrichtung eine geringe Höhe aufweist und dass über das Getriebe relativ große Kräfte bei Verwendung eines kleinen Antriebs erzeugt werden können.at another embodiment shut down the axes of the sonotrode and the counter tool on the one hand and the On the other hand drive an angle between 0 ° and 180 °, and it is a transmission interposed. This embodiment has the advantage that the device has a low height and that over the Gear relatively large personnel can be generated when using a small drive.
