Description
Stand der TechnikState of the art
Die vorliegende Erfindung betrifft ein Verfahren zum Versiegeln einer Verpackung mit einer Verpackungsvorrichtung. Insbesondere erfolgt dabei eine Störgrößenerkennung und -elimination. Bei der Verpackungsvorrichtung handelt es sich insbesondere um eine Schlauchbeutelmaschine. Des Weiteren betrifft die Erfindung eine Verpackungsvorrichtung, insbesondere zum Durchführen des Verfahrens.The present invention relates to a method of sealing a package with a packaging device. In particular, a disturbance variable recognition and elimination is carried out. The packaging device is in particular a tubular bag machine. Furthermore, the invention relates to a packaging device, in particular for carrying out the method.
Beim Verpacken von Produkten, beispielsweise Lebensmittel oder Medizintechnikprodukten, ist es sehr wichtig, dass die Verpackungen luftdicht und im pharmazeutischen Bereich auch steril sind. Diese Bedingungen können nur eingehalten werden, sofern keine Leckagen an der Verpackung vorhanden sind. Oft entstehen die Leckagen an den Siegelnähten der Verpackung. Bei einer Heißsiegelung werden zwei oder mehrere thermoplastische Schichten einer Folie in Kontakt miteinander gebracht und gegeneinandergedrückt. Eine Wärmezufuhr über die Siegelbacken führt dann dazu, dass die Schichten sich verbinden. Diese Verbindung wird als Siegelnaht bezeichnet. Verläuft dieser Siegelprozess nicht optimal ab oder befindet sich beispielsweise ein Teil des Produktes in der Siegelnaht, kann es zu einer undichten Siegelnaht kommen. Die Druckschrift
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren mit den Merkmalen nach Anspruch 1 bietet, im Unterschied zum Stand der Technik, nicht nur die Möglichkeit eine fehlerhafte Siegelnaht zu erkennen, sondern ermittelt auch die zur fehlerhaften Siegelnaht führende Fehlerursache. Basierend auf der erkannten Fehlerursache kann die entsprechende Steuergröße ermittelt werden. Durch verändern wiederum dieser Steuergröße an den entsprechenden Bestandteilen der Verpackungsmaschine wird die Fehlerursache, welche auch als Störgröße bezeichnet wird, vermieden bzw. ausgeregelt. So wird mit dem erfindungsgemäßen Verfahren nicht nur erkannt, dass eine Siegelnaht fehlerhaft ist, sondern es wird die Fehlerursache, beispielsweise das Vorhandensein eines Produktes in der Siegelnaht, eine Fehlfaltung an der Siegelnaht, eine Schiefstellung der Siegelbacken, lose Siegelbacken oder eine Determination der Siegelbacken, erkannt. Diese Vorteile werden erreicht durch ein Verfahren mit den Merkmalen des Anspruchs 1 zum Versiegeln einer Verpackung mit einer Verpackungsvorrichtung. Die Verpackungsvorrichtung umfasst eine Siegelvorrichtung. Die Siegelvorrichtung wiederum umfasst eine, zwei oder mehrere Siegelbacken zum Erzeugen einer Siegelnaht an der Verpackung. Bei der Verpackung handelt es sich insbesondere um eine Folie aus thermoplastischem Kunststoff. Vorzugsweise erfolgt das Erzeugen der Siegelnaht an einem Siegelbacken oder zwischen mehreren Siegelbacken durch eine Erwärmung. Zum Erzeugen der Wärme an der Siegelnaht wird zumindest einer der Siegelbacken über eine Heizvorrichtung erwärmt oder in Vibration versetzt. Findet die Erwärmung der Siegelnaht durch Vibration statt, kann eine der Siegelbacken auch als Amboss und die andere als Hammer bezeichnet werden. Erfindungsgemäß erfolgt ein (i) Erfassen, vorzugsweise ein Messen, einer ersten Größe an der Siegelvorrichtung. Dabei wird insbesondere direkt an den Siegelbacken oder an einer anderen geeigneten Stelle der Siegelvorrichtung gemessen. (ii) Im nächsten Schritt erfolgt ein Erzeugen eines ersten Signals aus der ersten Größe über der Zeit. (iii) Ferner wird eine sogenannte Fehlermatrix bereitgestellt. Die Fehlermatrix umfasst mehrere mögliche Fehlerursachen für fehlerhafte Siegelnähte und jeweils, zu den Fehlerursachen zugehörige erste Vergleichswerte. (iv) Das erste Signal oder eine entsprechende Transformation des ersten Signals wird mit den ersten Vergleichswerten der Fehlermatrix verglichen. Bei einer vollständigen oder teilweisen Übereinstimmung des ersten Signals oder der Transformation des ersten Signals mit einem der ersten Vergleichswerte kann die zugehörige Fehlerursache bestimmt oder ermittelt werden. Der einzelne erste Vergleichswert umfasst im einfachsten Fall einen bestimmten Wert oder Wertebereich. Jedoch können auch mehrere Einzelwerte oder der Verlauf eines Wertes den „ ersten Vergleichswert“ darstellen. (v) Daraufhin erfolgt eine Ausgabe der Fehlerursache. Die Fehlerursache kann unmittelbar zur Steuerung der Verpackungsvorrichtung verwendet werden. Diese Variante wird später noch im Detail beschrieben. Zusätzlich oder alternativ kann die Fehlerursache an den Bediener der Verpackungsvorrichtung ausgegeben werden, sodass dieser entsprechende Schritte einleiten kann. Weiter kann die Fehleruhrsache zur statistischen Auswertung gespeichert werden. Insbesondere ist zu folgenden Fehlerursachen in der Fehlermatrix jeweils zumindest ein erster Vergleichswert hinterlegt:
Vorhandensein eines Produktes in der Siegelnaht, und/oder
Vorhandensein eines Produktes in der Siegelnaht durch Stauben bei der Befüllung, und/oder
Vorhandensein eines Produktes in der Siegelnaht durch Nachrieseln bei der Befüllung, und/oder
Vorhandensein eines Produktes in der Siegelnaht durch elektrostatische Aufladung der Verpackungsfolie, und/oder
Fehlfaltung an der Siegelnaht, und/oder
Schiefstellung der Siegelbacken, und/oder
lose Siegelbacken, und/oder
Determination der Siegelbacken.
Die Fehlermatrix kann dabei beliebig aufgebaut sein. So können einer Fehlerursache auch mehrere erste Vergleichswerte zugeordnet werden. Ebenso ist es auch möglich, dass mehreren Fehlerursachen die gleichen ersten Vergleichswerte zugeordnet werden, wobei dann die exakte Bestimmung der Fehlerursache basierend auf einer zweiten Größe oder mehreren zweiten Größen erfolgt (diese Variante wird noch im Detail beschrieben).The inventive method with the features of claim 1 offers, in contrast to the prior art, not only the ability to detect a faulty sealed seam, but also determines the cause of the faulty seal seam root cause. Based on the recognized cause of the error, the corresponding control variable can be determined. By changing in turn this control variable to the corresponding components of the packaging machine, the cause of the error, which is also referred to as a disturbance, avoided or corrected. Thus, with the method according to the invention, it is not only recognized that a sealed seam is defective, but the cause of the error, for example the presence of a product in the sealed seam, a misfolding at the sealed seam, a skewing of the sealing jaws, loose sealing jaws or a determination of the sealing jaws, recognized. These advantages are achieved by a method having the features of claim 1 for sealing a package with a packaging device. The packaging device comprises a sealing device. The sealing device in turn comprises one, two or more sealing jaws for producing a sealed seam on the packaging. The packaging is in particular a film made of thermoplastic material. Preferably, the sealing seam is produced on a sealing jaw or between a plurality of sealing jaws by heating. To generate the heat at the sealing seam, at least one of the sealing jaws is heated by means of a heating device or caused to vibrate. If the heating of the sealed seam takes place by vibration, one of the sealing jaws can also be referred to as anvil and the other as a hammer. According to the invention, a (i) detection, preferably a measurement, of a first variable takes place on the sealing device. In particular, it is measured directly at the sealing jaws or at another suitable location of the sealing device. (ii) In the next step, a first signal of the first magnitude is generated over time. (iii) Further, a so-called error matrix is provided. The error matrix includes several possible causes of errors for defective seal seams and, in each case, first comparison values associated with the error causes. (iv) The first signal or a corresponding transformation of the first signal is compared with the first comparison values of the error matrix. In a complete or partial agreement of the first signal or the transformation of the first signal with one of the first comparison values, the associated cause of the error can be determined or determined. The single first comparison value comprises in the simplest case a specific value or value range. However, several individual values or the course of a value can also represent the "first comparison value". (v) Then the cause of the error is output. The cause of the error can be used directly to control the packaging device. This variant will be described later in detail. Additionally or alternatively, the cause of the fault can be output to the operator of the packaging device so that he can initiate corresponding steps. Furthermore, the error case can be stored for statistical evaluation. In particular, at least one first comparison value is stored in each case for the following error causes in the error matrix:
Presence of a product in the sealed seam, and / or
Presence of a product in the sealed seam due to dust during filling, and / or
Presence of a product in the sealed seam by Nachrieseln during filling, and / or
Presence of a product in the sealed seam by electrostatic charging of the packaging film, and / or
Misfolding at the seal, and / or
Misalignment of the sealing jaws, and / or
loose sealed jaws, and / or
Determination of the sealing jaws.
The error matrix can be constructed as desired. Thus, a first cause of error can also be assigned to several first comparison values. Likewise, it is also possible for the same first comparison values to be assigned to a plurality of error causes, the exact determination of the cause of the error then being based on a second size or a plurality of second sizes (this variant will be described in detail).
Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung.The dependent claims show preferred developments of the invention.
Das Verfahren wird insbesondere in einer Recheneinheit ausgeführt. Damit wird das Bereitstellen der Fehlermatrix und der Vergleich des ersten Signals oder der Transformation des ersten Signals mit den ersten Vergleichswerten zum Bestimmen der zugehörigen Fehlerursache vorzugsweise in der Recheneinheit ausgeführt. Selbstverständlich kann die „Recheneinheit“ aus mehreren einzelnen, zusammengefassten oder örtlich getrennten Untereinheiten bestehen und/oder in das Steuergerät für die Verpackungsvorrichtung oder die Siegelvorrichtung integriert sein.The method is executed in particular in a computing unit. Thus, the provision of the error matrix and the comparison of the first signal or the transformation of the first signal with the first comparison values for determining the associated cause of the error are preferably carried out in the arithmetic unit. Of course, the "arithmetic unit" consist of several individual, combined or spatially separated subunits and / or integrated into the control device for the packaging device or the sealing device.
Vorzugsweise ist vorgesehen, dass eine Änderung der ersten Größe auf einer mechanischen Schwingung, insbesondere dem Körperschall, der Siegelbacken basiert. Insbesondere werden hierzu Vibrationen, beispielsweise mit einer Piezo-Keramik, an der Siegelvorrichtung, insbesondere an den Siegelbacken, aufgenommen. Durch die Vibrationen kommt es zu einer Verformung der Piezo-Keramik und somit zur Ladungstrennung. Diese Ladungstrennung wird tatsächlich gemessen und in Spannungswerte gewandelt. Es erfolgt also ein Erfassen der Spannungswerte als „erste Größe“. Diese erste Größe bildet über der Zeit das „erste Signal“. It is preferably provided that a change of the first variable is based on a mechanical vibration, in particular the structure-borne noise, of the sealing jaws. In particular, for this purpose, vibrations, for example with a piezoelectric ceramic, are received on the sealing device, in particular on the sealing jaws. The vibrations lead to a deformation of the piezo ceramic and thus to charge separation. This charge separation is actually measured and converted into voltage values. Thus, the voltage values are recorded as the "first variable". This first variable forms the "first signal" over time.
Bereits dieses erste Signal kann in der Fehlermatrix mit entsprechenden ersten Vergleichswerten verglichen werden. In diesem Fall ist es möglich, dass die ersten Vergleichswerte ebenfalls einen Spannungsverlauf über der Zeit darstellen oder beispielsweise nur einzelne markante Spannungswerte als „erste Vergleichswerte“ hinterlegt sind. Wenn das auf der ersten Größe basierende erste Signal vollständig oder teilweise mit einem ersten Vergleichswert übereinstimmt oder in definierter Weise von dem ersten Vergleichswert abweicht, kann so die zugehörige Fehlerursache bestimmt werden.Already this first signal can be compared in the error matrix with corresponding first comparison values. In this case, it is possible that the first comparison values likewise represent a voltage curve over time or, for example, only individual significant voltage values are stored as "first comparison values". If the first signal based on the first quantity completely or partially coincides with a first comparison value or differs in a defined manner from the first comparison value, then the associated cause of the error can be determined.
So ist bevorzugt vorgesehen, dass das erste Signal eine elektrische Spannung über der Zeit angibt und in der Fehlermatrix entsprechende erste Vergleichswerte mit Spannungswerten und/oder Spannung-Zeitverläufen hinterlegt sind.Thus, it is preferably provided that the first signal indicates an electrical voltage over time and corresponding first comparison values with voltage values and / or voltage-time profiles are stored in the error matrix.
Zusätzlich oder alternativ zum Vergleichen des ersten Signals mit den ersten Vergleichswerten der Fehlermatrix, ist auch bevorzugt vorgesehen, das erste Signal zu transformieren und das Ergebnis der Transformation mit entsprechenden ersten Vergleichswerten der Fehlermatrix zu vergleichen. Selbstverständlich umfasst in diesem Fall die Fehlermatrix entsprechende erste Vergleichswerte die zur Transformation des ersten Signals passen.In addition or as an alternative to comparing the first signal with the first comparison values of the error matrix, it is also preferably provided to transform the first signal and to compare the result of the transformation with corresponding first comparison values of the error matrix. Of course, in this case the error matrix comprises corresponding first comparison values which match the transformation of the first signal.
Ferner ist auch bevorzugt vorgesehen, dass das erste Signal mehreren verschiedenen Transformationen unterzogen wird und das Ergebnis nach mehreren Transformationen mit ersten Vergleichswerten der Fehlermatrix verglichen wird.Furthermore, it is also preferably provided that the first signal is subjected to a plurality of different transformations and the result after several transformations is compared with first comparison values of the error matrix.
Bei dem Vergleich des ersten Signals bzw. einer Transformation des ersten Signals mit den ersten Vergleichswerten können unterschiedlichste Auswerteverfahren zum Einsatz kommen. Es ist insbesondere vorgesehen, am ersten Signal bzw. der Transformation Extremwerte, Wendepunkte, Integrale (Flächen unter Abschnitten des Signals), Differentiationen (Steigung), Totzeiten oder weitere mathematischen Auswerteverfahren zu ermitteln und diese Werte mit entsprechenden ersten Vergleichswerten zu vergleichen.When comparing the first signal or a transformation of the first signal with the first comparison values, a wide variety of evaluation methods can be used. In particular, it is provided to determine extreme values, inflection points, integrals (areas under sections of the signal), differentiations (slope), dead times or further mathematical evaluation methods on the first signal or the transformation, and to compare these values with corresponding first comparison values.
Bevorzugt ist vorgesehen, dass in dem Verfahren ein Erfassen, vorzugsweise Messen, zumindest einer weiteren Größe an der Siegelvorrichtung erfolgt. Die Fehlermatrix beinhaltet zumindest zu einer Fehlerursache, vorzugsweise zu mehreren oder allen hinterlegten Fehlerursachen, zusätzlich zum ersten Vergleichswert einen zweiten Vergleichswert. Es erfolgt ein Vergleichen der weiteren Größe, eines auf der weiteren Größe basierenden weiteren Signals und/oder einer weiteren Transformation des weiteren Signals mit dem zumindest einen zweiten Vergleichswert. It is preferably provided that in the method a detection, preferably measuring, of at least one further variable takes place on the sealing device. The error matrix includes, at least for one cause of the error, preferably for several or all stored error causes, in addition to the first comparison value, a second comparison value. The further variable, a further signal based on the further variable, and / or a further transformation of the further signal with the at least one second comparison value are compared.
Vorzugsweise gibt es zu mehreren oder allen Fehlerursachen zweite Vergleichswerte in der Fehlermatrix. Das Bestimmen der zugehörigen Fehlerursache basiert vorzugsweise sowohl auf dem Vergleich des ersten Signals (und/oder einer Transformation des ersten Signals) mit den ersten Vergleichswerten und der weiteren Größe (und/oder eines weiteren Signals basierend auf der weiteren Größe und/oder einer Transformation des weiteren Signals) mit den zweiten Vergleichswerten.Preferably, for several or all error causes, there are second comparison values in the error matrix. Determining the associated error cause is preferably based both on the comparison of the first signal (and / or a transformation of the first signal) with the first comparison values and the further variable (and / or a further signal based on the further variable and / or a transformation of the further signal) with the second comparison values.
Durch die Verwendung der ersten Größe und der zumindest einen weiteren Größe kann die Fehlerursache noch genauer bestimmt werden. Eine Änderung der weiteren Größe basiert insbesondere auf:
einem Abstand zwischen den zwei Siegelbacken und/oder
einer Temperatur der Siegelbacken und/oder
einem Spannungswert oder Stromwert der Mechanik zum Bewegen der Siegelbacken und/oder
einem Druck oder einer Kraft an oder zwischen den Siegelbacken.
Unter der Mechanik zum Bewegen der Siegelbacken sind auch hydraulische oder pneumatische Anordnungen zu verstehen.By using the first size and the at least one further size, the cause of the error can be determined even more accurately. A change of the further size is based in particular on:
a distance between the two sealing jaws and / or
a temperature of the sealing jaws and / or
a voltage value or current value of the mechanism for moving the sealing jaws and / or
a pressure or a force on or between the sealing jaws.
The mechanics for moving the sealing jaws also include hydraulic or pneumatic arrangements.
In einer einfachen Ausführungsform wird die ermittelte Fehlerursache lediglich ausgegeben. Besonders bevorzugt ist jedoch vorgesehen, dass die ausgegebene Fehlerursache unmittelbar auch dazu genutzt wird, um die Fehlerursache zu minimieren, zu vermeiden oder zu eliminieren. Dies kann insbesondere im laufenden Betrieb der Verpackungsvorrichtung erfolgen. Hierzu erfolgt ein bereitstellen eines Regelalgorithmus, welcher einer oder mehrere Steuergrößen für die Verpackungsvorrichtung umfasst. Der Regelalgorithmus kann beispielsweise als Mehrgrößenregler oder mit voneinander entkoppelten Eingrößenreglern oder sonstigen Reglern (z.B. Zustandsrückführung) ausgeführt sein. Die Abhängigkeit der Fehleruhrsachen bzw. der Störgröße auf die Ausgangsgrößen sind aus dem Systemverhalten bekannt. Bei manchen Regelverfahren sind diese in einer Matrix (hier als Ein-Ausgans-Matrix oder Regelmatrix bezeichnet) hinterlegt. Nach Ermittlung der Fehlerursache werden die Steuergrößen durch einen Regler nachgestellt, welche die Fehlerursache bzw. die Störgrößen eliminieren. Wird für jede Steuergröße ein individueller Regler verwendet, wird zuerst anhand der ermittelten Fehlerursache und der Regelmatrix, die Steuergrößen ermittelt, welche den Fehler eliminieren. Im nächsten Schritt erfolgt ein Ausregeln der Fehlerursache durch Verändern der bestimmten Steuergröße in der Verpackungsvorrichtung.In a simple embodiment, the determined cause of the error is merely output. However, it is particularly preferred that the output error cause is also used directly to minimize, avoid or eliminate the cause of the error. This can be done in particular during operation of the packaging device. For this purpose, a control algorithm is provided which comprises one or more control variables for the packaging device. The control algorithm may be implemented, for example, as a multi-variable controller or with one-off or other controllers isolated from one another (for example state feedback). The dependence of the error cases or the disturbance on the output variables are known from the system behavior. In some control methods, these are stored in a matrix (referred to here as an input-output matrix or rule matrix). After determining the cause of the error, the control variables are readjusted by a controller which eliminates the cause of the error or the disturbance variables. If an individual controller is used for each control variable, the control variables which eliminate the error are first determined on the basis of the determined error cause and the control matrix. In the next step, the error cause is corrected by changing the specific control variable in the packaging device.
Insbesondere ist eine Siegelbackensteuerung vorgesehen, die zumindest die Bewegung einer Siegelbacke und/oder die Temperatur der Siegelbacke steuert. Vorzugsweise ist vorgesehen, dass zumindest eine der Steuergrößen aus der Regelmatrix in der Siegelbackensteuerung zum Verändern der Siegelkraft und/oder der Siegelbackentemperatur und/oder des Siegelbackenabstands und/oder des Motorstrom und/oder der Motorspannung und/oder des Motormoments, genutzt wird. Der Motor wird dabei zum Bewegen der zumindest einen Siegelbacke genutzt.In particular, a sealing jaw control is provided, which controls at least the movement of a sealing jaw and / or the temperature of the sealing jaw. It is preferably provided that at least one of the control variables from the control matrix in the sealing jaw control is used for changing the sealing force and / or the sealing jaw temperature and / or the sealing jaw spacing and / or the motor current and / or the motor voltage and / or the motor torque. The motor is used to move the at least one sealing jaw.
Ferner ist bevorzugt vorgesehen, dass die Verpackungsvorrichtung eine Befüllvorrichtung umfasst. Mittels dieser Befüllvorrichtung erfolgt das Befüllen der Verpackung. Beispielsweise bei der Verpackung von Pulver in einer Schlauchbeutelmaschine kann es dazu kommen, dass die Befüllvorrichtung nicht schnell genug oder sauber schließt. Dadurch kann ein Teil des Pulvers in die Siegelnaht rieseln und es kommt zu einer fehlerhaften Siegelnaht. So ist bevorzugt vorgesehen, dass zumindest eine der Steuergrößen aus der Regelmatrix in einer entsprechenden Befüllvorrichtungssteuerung, insbesondere hinsichtlich Befüllmenge und/oder Befüllgeschwindigkeit, genutzt wird.Furthermore, it is preferably provided that the packaging device comprises a filling device. By means of this filling the filling of the packaging takes place. For example, when packaging powder in a tubular bag machine, it may happen that the filling device does not close fast enough or clean. As a result, a portion of the powder trickle into the sealed seam and there is a faulty sealed seam. Thus, it is preferably provided that at least one of the control variables from the control matrix is used in a corresponding filling device control, in particular with regard to the filling amount and / or the filling speed.
Die Erfindung umfasst des Weiteren eine Verpackungsvorrichtung, insbesondere eine Schlauchbeutelmaschine. Die Verpackungsvorrichtung ist vorzugsweise zur Durchführung des oben beschriebenen Verfahrens ausgebildet. Die Verpackungsvorrichtung umfasst eine Siegelvorrichtung mit einer, zwei oder mehreren Siegelbacken zum Erzeugen einer Siegelnaht an einer Verpackung. Ferner ist eine Erfassungseinheit vorgesehen. Die Erfassungseinheit ist zum Erfassen, insbesondere Messen, der ersten Größe an der Siegelvorrichtung ausgebildet. Ferner ist eine Recheneinheit vorgesehen. Die Recheneinheit dient zum Erzeugen des ersten Signals aus der ersten Größe über der Zeit; zum Bereitstellen der Fehlermatrix; zum Vergleichen des ersten Signals bzw. einer entsprechenden Transformation mit den ersten Vergleichswerten der Fehlermatrix, um so die zugehörige Fehlerursache zu bestimmen; und zur Ausgabe der bestimmten Fehlerursache.The invention further comprises a packaging device, in particular a tubular bag machine. The packaging device is preferably designed for carrying out the method described above. The packaging device comprises a sealing device with one, two or more sealing jaws for producing a sealed seam on a packaging. Furthermore, a detection unit is provided. The detection unit is designed to detect, in particular measure, the first variable on the sealing device. Furthermore, a computing unit is provided. The arithmetic unit is used to generate the first signal of the first magnitude over time; for providing the error matrix; for comparing the first signal or a corresponding transformation with the first comparison values of the error matrix so as to determine the associated error cause; and to output the specific cause of the error.
