Description
Die Erfindung betrifft eine Haftmittelzuführeinrichtung zum Zuführen eines Haftmittels nach dem Oberbegriff von Anspruch 1.The invention relates to an adhesive supply device for supplying an adhesive according to the preamble of claim 1.
Im Bereich der Möbelindustrie werden verbreitet Oberflächen von Möbelfronten, Korpusteilen, etc. mit Beschichtungsmaterial versehen, insbesondere auch die Schmalflächen solcher Werkstücke. Das Beschichtungsmaterial wird dabei unter Einsatz eines Haftmittels (Kleber, Leim) an die Werkstücke aufgebracht. Für die Aufbringung eines solchen Beschichtungsmaterials (z. B. einer Kante) im Bereich der Werkstückschmalfläche sind sogenannte Kantenanleimmaschinen bekannt.In the furniture industry, surfaces of furniture fronts, carcass parts, etc. are commonly provided with coating material, in particular also the narrow surfaces of such workpieces. The coating material is applied to the workpieces using an adhesive (glue, glue). For the application of such a coating material (eg an edge) in the region of the workpiece surface, so-called edge banding machines are known.
Der Kleber wird hierbei zur Verarbeitung erwärmt und aufgeschmolzen und mittels einer Leimwalze zur Übertragung auf die Kante und/oder das Werkstück bereitgestellt.The adhesive is hereby heated for processing and melted and provided by means of a glue roller for transfer to the edge and / or the workpiece.
Der Leim bzw. das Haftmittel wird häufig in Form von Granulat in einem Vorratsbehälter bevorratet. Zum Aufschmelzen des Leims ist an oder in dem Vorratsbehälter eine Heizung vorgesehen, die den meist aus Metall bestehenden Vorratsbehälter erwärmt, so dass das in dem Vorratsbehälter vorgesehene Haftmittel aufschmilzt.The glue or the adhesive is often stored in the form of granules in a storage container. In order to melt the glue, a heater is provided on or in the storage container, which heats the storage container, which is usually made of metal, so that the adhesive provided in the storage container melts.
Darüber hinaus ist im Inneren des Vorratsbehälters üblicherweise ein Messfühler vorgesehen, der den Füllstand des Haftmittels innerhalb des Vorratsbehälters überwacht. Der Fühler erstreckt sich dabei meist im Inneren des Haftmittelvorratsbehälters bis hin zu dessen Boden.In addition, usually a sensor is provided inside the reservoir, the level the adhesive is monitored within the reservoir. The sensor usually extends inside the adhesive reservoir up to the bottom.
Obgleich derartige Haftmittelzuführeinrichtungen eine zuverlässige Versorgung von Kantenanleimmaschinen oder dergleichen mit dem benötigten Haftmittel gewährleisten, hat sich gezeigt, dass bisweilen Störungen und Betriebsunterbrechungen der Maschine in Folge einer ungenauen oder fehlerhaften Füllstandsmessung des Haftmittels auftreten können, und dass bekannte Füllstandsmesseinrichtungen mit einem beträchtlichen Wartungsaufwand verbunden sind.Although such adhesive supply means ensure reliable supply of edge banding machines or the like with the required adhesive, it has been found that sometimes malfunctions and service interruptions of the machine may occur as a result of inaccurate or erroneous level measurement of the adhesive and known level measurement devices are associated with considerable maintenance.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Haftmittelzuführeinrichtung der eingangs genannten Art bereitzustellen, die bei einfacher Konstruktion eine zuverlässige und wartungsarme Überwachung des Haftmittelfüllstandes ermöglicht.The invention is therefore based on the object to provide an adhesive supply device of the type mentioned, which allows a simple and reliable construction low-maintenance monitoring of the adhesive level.
Diese Aufgabe wird erfindungsgemäß durch eine Haftmittelzuführeinrichtung nach Anspruch 1 gelöst. Besonders bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by an adhesive supply according to claim 1. Particularly preferred embodiments of the invention are specified in the dependent claims.
Der Erfindung liegt die Erkenntnis zugrunde, dass die im Stand der Technik auftretenden Schwierigkeiten primär dadurch verursacht werden, dass die Füllstandsmesseinrichtung in das bevorratete Haftmittel eingetaucht ist. Dies führt dazu, dass sich mit der Zeit zunehmend Haftmittel an der Füllstandsmesseinrichtung ablagert, was die Zuverlässigkeit und Genauigkeit der Füllstandsmessung beeinträchtigen und Wartungsarbeiten erforderlich machen kann. Vor diesem Hintergrund sieht die Erfindung vor, dass bei einer Haftmittelzuführeinrichtung der eingangs genannten Art die Füllstandsmesseinrichtung derart angeordnet und eingerichtet ist, dass sie den Füllstand eines in dem Haftmittelvorratsbehälter bevorrateten Haftmittels ohne Berührung mit dem Haftmittel messen kann.The invention is based on the finding that the difficulties occurring in the prior art are primarily caused by the fact that the level measuring device is immersed in the stored adhesive. As a result, adhesive is increasingly deposited on the level measuring device over time, which may affect the reliability and accuracy of the level measurement and may require maintenance. Against this background, the invention provides that in an adhesive supply device of the type mentioned, the level measuring device arranged and set up in that it can measure the level of adhesive stored in the adhesive reservoir without contact with the adhesive.
Auf diese Weise muss die Füllstandsmesseinrichtung nicht mehr in den Haftmittelvorrat eingetaucht werden, so dass die eingangs beschriebenen Nachteile des Standes der Technik beseitigt werden können, da die Füllstandsmesseinrichtung nicht mehr durch Haftmittelablagerungen und -verklumpungen beeinträchtigt wird. Hierdurch ergibt sich eine verbesserte Zuverlässigkeit und Genauigkeit der Füllstandsmessung und ein verminderter Wartungsaufwand. Dabei ist zu beachten, dass diese Vorteile erzielt werden können, ohne dass sich eine kompliziertere Konstruktion der Haftmittelzuführeinrichtung ergibt.In this way, the fill level measuring device no longer needs to be immersed in the adhesive reservoir, so that the disadvantages of the prior art described above can be eliminated, since the fill level measuring device is no longer affected by adhesive deposits and lumps. This results in improved reliability and accuracy of the level measurement and reduced maintenance. It should be noted that these advantages can be achieved without resulting in a more complicated construction of the adhesive supply device.
Die Füllstandsmesseinrichtung kann im Rahmen der vorliegenden Erfindung auf unterschiedliche Art und Weise ausgestattet sein. Als besonders zuverlässig, präzise und wartungsarm hat es sich jedoch erwiesen, dass die Füllstandsmesseinrichtung gemäß einer Weiterbildung der Erfindung mindestens ein berührungslos arbeitendes Messelement aufweist, das bevorzugt ein kapazitives Messelement ist.The fill level measuring device can be equipped in different ways in the context of the present invention. However, it has proved to be particularly reliable, precise and low-maintenance that, according to a development of the invention, the fill level measuring device has at least one non-contact measuring element, which is preferably a capacitive measuring element.
Gemäß einer Weiterbildung der Erfindung ist ferner vorgesehen, dass mindestens ein Messelement oberhalb eines in dem Haftmittelvorratsbehälter bevorrateten Haftmittels angeordnet ist. Hierdurch können Veränderungen des Haftmittelvorrats besonders leicht und präzise erfasst werden, und das jeweilige Messelement ist leicht zu Anschlusszwecken oder dergleichen zugänglich.According to a development of the invention, it is further provided that at least one measuring element is arranged above an adhesive stored in the adhesive reservoir. As a result, changes in the adhesive supply can be detected particularly easily and precisely, and the respective measuring element is easily accessible for connection purposes or the like.
Gemäß einer Weiterbildung der Erfindung ist ferner vorgesehen, dass mindestens ein Messelement in oder auf einem Deckel für den Haftmittelvorratsbehälter vorgesehen ist. Hierdurch ergibt sich nicht nur eine einfache Konstruktion, da keine zusätzlichen Trägerbauteile oder dergleichen benötigt werden, sondern das jeweilige Messelement kann auch vor Beschädigungen etc. beschützt werden.According to one embodiment of the invention, it is further provided that at least one measuring element is provided in or on a lid for the adhesive reservoir. This not only results in a simple construction, since no additional support components or the like are needed, but the respective measuring element can also be protected from damage, etc.
Darüber hinaus ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass die Haftmittelzuführeinrichtung ferner mindestens einen Isolierabschnitt aufweist, der zumindest bereichsweise eine geringere Wärmeleitfähigkeit aufweist als das Grundmaterial des Haftmittelvorratsbehälters. Ein derartiger Isolierabschnitt leistet einen wesentlichen Beitrag zu einer zuverlässigen und präzisen Füllstandsmessung, da die Füllstandsmesseinrichtung oder andere hiermit verknüpfte Bauteile mittels des Isolierabschnitts thermisch von dem Haftmittelvorratsbehälter und insbesondere der Aufschmelzeinrichtung entkoppelt werden können. Ohne thermische Entkopplung bestünde die Gefahr, dass die von der Aufschmelzeinrichtung direkt oder über den Haftmittelvorratsbehälter zugeführte Wärme das Ergebnis der Füllstandsmessung beeinträchtigt oder gar Beschädigungen der Füllstandsmesseinrichtung verursachen kann.In addition, according to a development of the invention, it is provided that the adhesive supply device further comprises at least one insulating section, which at least partially has a lower thermal conductivity than the base material of the adhesive reservoir. Such an insulating section makes a significant contribution to a reliable and precise level measurement, since the fill level measuring device or other components associated therewith can be thermally decoupled from the adhesive reservoir and in particular the melting device by means of the insulating section. Without thermal decoupling there would be a risk that the heat supplied by the melting device directly or via the adhesive reservoir could impair the result of the level measurement or even cause damage to the level measuring device.
Um diese Schutzfunktion besonders wirksam ausüben zu können, ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass mindestens ein Isolierabschnitt zwischen dem Haftmittelvorratsbehälter und mindestens einem Messelement angeordnet ist.In order to be able to exert this protective function particularly effectively, it is provided according to a development of the invention that at least one insulating section is arranged between the adhesive reservoir and at least one measuring element.
Das Material des Isolierabschnitts kann im Rahmen der vorliegenden Erfindung aus unterschiedlichsten Isoliermaterialien ausgewählt sein, wobei es sich nicht notwendigerweise um klassische Isoliermaterialien handeln muss. Dabei ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass mindestens ein Isolierabschnitt einen künstlichen Faserverbundwerkstoff aufweist, wie insbesondere Glasfaser und/oder Kohlefaser. Diese Fasern isolieren besonders wirksam und tragen dabei vorteilhaft zur thermischen Entkopplung bei. Ferner sind die Glasfasern in der Anschaffung günstig, wodurch sich der Preis der erfindungsgemäßen Vorrichtung reduziert.The material of the insulating portion may be selected in the context of the present invention from a variety of insulating materials, which need not necessarily be classic insulating materials. It is provided according to a development of the invention that at least one insulating section has an artificial fiber composite material, in particular glass fiber and / or carbon fiber. These fibers insulate particularly effectively and contribute to the thermal decoupling advantageous. Furthermore, the glass fibers are in the purchase low, thereby reducing the price of the device according to the invention.
Darüber hinaus ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass die Haftmittelzuführeinrichtung selbst eine Elektronik zum Auswerten des Messergebnisses der Füllstandsmesseinrichtungen aufweist. Hierdurch lässt sich nicht nur die Auswertegenauigkeit verbessern, sondern es ergibt sich auch eine vereinfachte Kabelführung und eine verminderte Anzahl von Anschlüssen. Dabei ist es besonders bevorzugt, dass die Auswerteelektronik in oder auf einem Deckel für den Haftmittelvorratsbehälter vorgesehen ist. Auf diese Weise wird die Auswerteelektronik sicher vor Beschädigungen und Umwelteinflüssen geschützt, und es ergibt sich eine einfache Konstruktion, bei der die Auswerteelektronik leicht mit der Füllstandsmesseinrichtung verknüpft werden kann. Die Auswerteelektronik kann dabei Anschlüsse aufweisen, so dass sie in ein Bussystem wie PROFIBUS, CAN, LIN, Flexray oder dergleichen integriert werden kann. Auf diese Weise vereinfacht sich nicht nur der Verkabelungsaufwand, sondern auch die Integration der Elektronik in die Haftmittelzuführeinrichtung bzw. in eine übergeordnete Maschineneinheit.In addition, according to a development of the invention, it is provided that the adhesive supply device itself has electronics for evaluating the measurement result of the fill level measuring devices. This not only improves the evaluation accuracy, but also results in a simplified cable management and a reduced number of connections. It is particularly preferred that the evaluation is provided in or on a lid for the adhesive reservoir. In this way, the transmitter is securely protected from damage and environmental influences, and there is a simple construction in which the transmitter can be easily linked to the level measuring device. The transmitter can have connections so that they can be integrated into a bus system such as PROFIBUS, CAN, LIN, Flexray or the like. In this way, not only simplifies the wiring, but also the integration of the electronics in the adhesive supply or in a higher-level machine unit.

Auf diese Weise verringert sich der Verkabelungsaufwand und es gehen weniger Kabel von dem Deckel 24 des Haftmittelvorratsbehälters 12 ab. Die Auswerteelektronik 22 kann dabei zusätzlich zu den Leistungsversorgungsanschlüssen eine Schnittstelle aufweisen, mit welcher es möglich ist, die Auswerteelektronik 22 in ein bestehendes Bussystem zu integrieren und somit die Messergebnisse der Füllstandsmesseinrichtung 16 direkt an die Auswerteelektronik 22 zu übertragen.In the

Als Materialien für den Isolierabschnitt eignen sich insbesondere Faserverbundwerkstoffe wie Glasfaser und/oder Kohlefaser.In order to limit the heat loss to the outside and to protect the
