Description

Die Erfindung richtet sich auf ein Verfahren zur Herstellung eines Markisentuchs durch Verbinden der sich überlappenden Randbereiche einzelner Tuchbahnen mittels eines Schmelzklebers, wobei die zu verbindenden Tuchbahnen an einer Heizeinrichtung vorbeigeführt werden, die einen zwischen den sich überlappenden Randbereichen der Tuchbahnen eingebrachten Schmelzkleberstreifen zum Schmelzen bringt, wodurch die Randbereiche verbunden werden.The The invention is directed to a method of making an awning fabric by connecting the overlapping ones Edge regions of individual fabric webs by means of a hotmelt adhesive, wherein the fabric webs to be connected are passed by a heating device, one between the overlapping ones Edge regions of the fabric webs introduced hot melt adhesive strip melts, whereby the edge areas are connected.

Die Qualität und Belastbarkeit eines auf diese Weise aus mehreren Tuchbahnen gebildeten Markisentuchs hängt sehr stark von der Festigkeit der Klebeverbindung der einzelnen Tuchbahnen ab, zumal aufgrund der größeren Dicke im Überlappungsbereich beim Aufrollen des Markisentuches zu einem Tuchwickel auf den Überlappungsbereich besonders starke Zugkräfte einwirken.The quality and load capacity of a plurality of fabric webs in this way formed awning hangs very strong on the strength of the adhesive bond of the individual Cloth webs, especially because of the greater thickness in the overlap area when winding the awning fabric to a cloth wrap on the overlap area particularly strong tensile forces act.

Eine gravierende Störung bei der Herstellung der Klebeverbindung besteht darin, dass der Schmelzkleber nicht die erforderliche Verarbeitungstemperatur erreicht. Dies kann daraus resultieren, dass die Heizeinrichtung nicht richtig funktioniert oder die Tuchbahnen relativ zur Heizeinrichtung beim Vorbeilaufen nicht richtig positioniert sind.A serious disorder in the preparation of the adhesive bond is that the hot melt adhesive not reached the required processing temperature. This can The result is that the heater is not working properly or the fabric sheets relative to the heater when passing not are positioned correctly.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Verfahren so zu verbessern, dass eine zuverlässige Qualitätskontrolle gewährleistet ist.Of these, Based on the invention, the object is based, a generic method so to improve that reliable quality control guaranteed is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in Förderrichtung hinter der Heizeinrichtung eine Temperaturmesseinrichtung zur Erfassung der Temperatur des Schmelzklebers angeordnet ist.These Task is inventively characterized solved, that in the conveying direction behind the heating device, a temperature measuring device for detection the temperature of the hot melt adhesive is arranged.

Durch diese Ausgestaltung ist es möglich, den Produktionsprozess umgehend unter Vermeidung der Produktion von Ausschussware zu unterbrechen, wenn der Schmelzkleber die Verarbeitungstemperatur nicht erreicht hat und dementsprechend davon auszugehen ist, dass die Klebeverbindung nicht die erforderliche Belastbarkeit aufweist.By this embodiment, it is possible to Production process immediately while avoiding the production of To interrupt rejects, when the hot melt adhesive is the processing temperature has not reached and therefore it can be assumed that the adhesive bond does not have the required load capacity.

Vorzugsweise ist die Heizeinrichtung eine Ultraschall-Heizeinrichtung, welche insbesondere ein als Widerlager dienendes Ambossrad und ein ultraschallbeaufschlagtes Sonotrodenrad umfasst, zwischen welchen die zu verbindenden Randabschnitte der Tuchbahnen durchbewegt werden.Preferably the heater is an ultrasonic heater, which in particular, an anvil wheel serving as an abutment and an ultrasonically charged one Sonotrodenrad comprises, between which the edge portions to be joined Cloth webs are moved through.

Als Temperaturmesseinrichtung kann mit Vorteil eine Infrarot-Messeinrichtung vorgesehen sein.When Temperature measuring device may be provided with advantage an infrared measuring device.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Die Zeichnung zeigt eine schematische Darstellung des Verbindungsbereichs zweier zu einem Markisentuch zu verbindenden Tuchbahnen.following The invention is based on a preferred embodiment in connection closer to the drawing explained. The drawing shows a schematic representation of the connection area two cloth sheets to be joined to an awning cloth.

In der Zeichnung ist der Randbereich 1 einer oberen Stoffbahn dargestellt, der den Randbereich 2 einer unteren Stoffbahn überlappt, wobei sich zwischen den beiden Randbereichen 1, 2 ein – gegebenenfalls armiertes – Schmelzkleberband 3 befindet.In the drawing is the border area 1 an upper panel representing the edge area 2 a lower panel overlaps, being between the two edge areas 1 . 2 a - possibly reinforced - hot melt adhesive tape 3 located.

Eine Ultraschall-Heizeinrichtung 4 umfasst ein als Widerlager dienendes oberes Ambossrad 5 und ein ultraschallbeaufschlagtes unteres Sonotrodenrad 6, zwischen welchen die Randbereiche 1, 2 der Tuchbahnen in Richtung des Pfeils 7 durchbewegt werden.An ultrasonic heater 4 comprises an upper anvil wheel serving as an abutment 5 and an ultrasonically loaded lower sonotrode wheel 6 between which the edge areas 1 . 2 the cloths in the direction of the arrow 7 be moved.

In Förderrichtung (Pfeil 7) hinter der Heizeinrichtung 4 ist eine Infrarot-Messeinrichtung 8 angeordnet, die mit einer Auswerteeinrichtung 9 verbunden ist. Die Auswerteeinrichtung 9 erzeugt in Abhängigkeit von dem Unterschreiten einer voreingestellten Temperaturschwelle, welche für den jeweils eingesetzten Schmelzkleber charakteristisch ist, ein Alarmsignal, durch welches einerseits optische Alarmeinrichtungen 10 und akustische Alarmeinrichtungen 11 angesteuert werden und andererseits die Tuchvorschub-Steuerung 12, um den Tuchvorschub automatisch zu unterbrechen.In conveying direction (arrow 7 ) behind the heater 4 is an infrared measuring device 8th arranged with an evaluation device 9 connected is. The evaluation device 9 generated in response to the falling below a preset temperature threshold, which is characteristic of the particular hot melt adhesive used, an alarm signal by which on the one hand optical alarm devices 10 and acoustic alarms 11 be controlled and on the other hand, the cloth feed control 12 to automatically stop the cloth feed.

Die Infrarot-Messeinrichtung 8 ist ein berührungslos arbeitendes Temperaturmessgerät, welches die Energiemenge erfasst, die von einem Objekt ausgesandt wird und hieraus den Temperaturwert berechnet. Die Messgenauigkeit liegt bei +/- 0,5°C. Die Messeinrichtung umfasst eine Linse, einen Spektralfilter, einen Sensor und eine elektronische Signalverarbeitungseinheit. Der Spektralfilter hat die Aufgabe, den interessierenden Wellenlängenbericht zu selektieren. Der Sensor wandelt die Infrarotstrahlung in elektrische Parameter um. Da die Intensität der ausgestrahlten Infrarotstrahlung materialabhängig ist, kann der typische Emissionsgrad des Materials am Messwertaufnehmer eingestellt werden.The infrared measuring device 8th is a non-contact temperature measuring device that measures the amount of energy emitted by an object and calculates the temperature value from it. The measuring accuracy is +/- 0.5 ° C. The measuring device comprises a lens, a spectral filter, a sensor and an electronic signal processing unit. The purpose of the spectral filter is to select the wavelength report of interest. The sensor converts the infrared radiation into electrical parameters. Since the intensity of the radiated infrared radiation is material-dependent, the typical emissivity of the material can be adjusted at the sensor.
