Description

Gerät zum Verbinden, z. B. Verleimen, Verkleben oder Verschweißen von Gegenständen aus Holz, thermoplastischen oder anderen Werkstoffen Im Patent 858 871 ist ein Gerät zum Verbinden, z. B. Verleimen, Verkleben oder Verschweißen von Gegenständen aus Holz, thermoplastisehen oder anderen Stoffen unter Einwirkung von Wärme, die mittels eines elektrischen Hochfrequenzfeldes erzeugt wird, beschrieben. Dieses Gerät besteht im wesentlichen aus einer ortsbeweglichen Handhabe, die vorzugsweise die Form einer Gabel oder Zange besitzt, und an der die Elektroden des Hochfrequenzfeldes angebracht sind. Gegenstand der Erfindung ist eine besonders vorteilhafte Weiterbildung des im Patent 858 871 angegebenen Gerätes, die in der Zeichnung in einem Ausführungsbeispiel dargestellt ist und im wesentlichen darin besteht, daß an der ortsbeweglichen Handhabe Überwachungsmittel zur Messung und bezw. oder Regelung der den zu verbindenden Stoffen zugeführten Wärmemenge vorgesehen sind, beispielsweise Mittel zur Messung und überwachung der zugeführten Wärmeleistung. Das. metallische Gehäuse i des Gerätes ist handgrifförmig ausgebildet und trägt mittels der Arme 2 und 3 die Hochfrequenzfeldelektroden 4 und 5. Der Arm 3 ist am Gehäuse gelenkig angebracht und kann mittels des Handhebels 6 entgegen einer Feder 7 bewegt werden. Die Teile i, 2, 3, 5 und 6 liegen an Erde und sind über die leitende Hülle des leicht beweglichen Zuführungskabels 8 an einen Pol der Hochfrequenzenergiequelle angeschlossen. Am zweiten Pol der Hoc'hfrequenzquelle liegt dieKabelseele 9, die in einem zylindrischen Körper io frei endet. Der Körper io besteht aus einem Material hoher Dielektrizitätskonstante und geringen Dipolverlustwinkels und ist von einer metallischen Hülse i i umgeben, an die mittels der Leitung 12 die Elektrode 4 angeschlossen ist. Der Körper io kann mittels der Rändelschraube 13 in der Längsrichtung verschoben werden, wodurch sich die kapazitive Kopplung zwischen 9-und ii ändert und somit die Elektrodenspannung anpassen läßt. Die Elektrode 4 ist an dem Arm 2 mittels der Stücke 14 aus hochfrequenzisolierendem Stoff befestigt, die Elektrode 5 ist am Arm 3 gelenkig angebracht.Device for connecting, e.g. As gluing, bonding or welding of articles made of wood, thermoplastic or other materials in Patent 858 871 is a device for connecting, for example. B. gluing, gluing or welding of objects made of wood, thermoplastic or other substances under the action of heat generated by means of a high-frequency electric field is described. This device consists essentially of a portable handle, which preferably has the shape of a fork or tongs, and to which the electrodes of the high-frequency field are attached. The subject of the invention is a particularly advantageous development of the device specified in patent 858 871 , which is shown in the drawing in an exemplary embodiment and essentially consists in the fact that monitoring means for measuring and respectively on the portable handle. or regulation of the amount of heat supplied to the substances to be connected are provided, for example means for measuring and monitoring the supplied heat output. That. The metallic housing i of the device is designed in the shape of a handle and carries the high-frequency field electrodes 4 and 5 by means of the arms 2 and 3. The arm 3 is attached to the housing in an articulated manner and can be moved against a spring 7 by means of the hand lever 6. Parts i, 2, 3, 5 and 6 are connected to earth and are connected to one pole of the high-frequency energy source via the conductive sheath of the easily movable feed cable 8. At the second pole of the high-frequency source lies the cable core 9, which ends freely in a cylindrical body. The body io consists of a material with a high dielectric constant and a low dipole loss angle and is surrounded by a metallic sleeve ii to which the electrode 4 is connected by means of the line 12. The body io can be displaced in the longitudinal direction by means of the knurled screw 13, as a result of which the capacitive coupling between 9- and ii changes and thus the electrode voltage can be adjusted. The electrode 4 is attached to the arm 2 by means of the pieces 14 of high-frequency insulating material, the electrode 5 is attached to the arm 3 in an articulated manner.

Zum Ein- und Ausschalten der Hochfrequenzenergiequelle ist ein in der Zeichnung nur schematisch angedeuteter Druckknopfschalter 15 vorgesehen, der mit einer Klemme am Handgriff und somit an Erde liegt, während die andere über die Leitung16 zu einem Relais od. dgl. führt. Von der Dicke der zu verleimenden Werkstücke hängt der Elektrodenabstand und somit bei gegebener Spannung die Feldstärke ab. Um die mittels der Schraube 13 veränderbare Spannung kontrollieren zu können, ist ein Meßins.trument 17, z. B. ein Hitzdrahtgerät, eingebaut, das mit einer Klemme an Erde und mit der anderen über einen Kondensator 18 an der Leitung 12 liegt. Das Hitzdrahtgerät 17 hat vorteilhaft eine in Zentimeter oder Millimeter geeichte Skala, um die Elektrodenspannung der Dicke des Werkstückes anpassen zu können. Das Gerät kann im Betrieb an das zu verleimende Werkstück federnd angeklemmt werden und braucht nicht vom Bedienungsmann gehalten zu werden. Da das Gerät an Erde liegt, kann es ohne Gefahr auch während des Betriebes angefaßt werden. Gegebenenfalls kann man das Gerät noch mit einem isolierenden Lacküberzug versehen, da sich eine ausreichende Erdung nicht immer durchführen läßt.An in the drawing only schematically indicated push-button switch 15 is provided, the with one clamp on the handle and thus on earth, while the other is on the Line16 to a relay or the like. Leads. The thickness of the workpieces to be glued depends on the electrode spacing and thus the field strength for a given voltage. In order to be able to control the voltage which can be changed by means of the screw 13 a measuring instrument 17, e.g. B. a hot wire device, built-in with a clamp is connected to earth and with the other via a capacitor 18 on the line 12. That The hot wire device 17 advantageously has a scale calibrated in centimeters or millimeters, in order to be able to adapt the electrode voltage to the thickness of the workpiece. The device can be resiliently clamped to the workpiece to be glued during operation and needs not to be held by the operator. Since the device is connected to earth, it can can be handled without risk even during operation. If necessary, you can the device is provided with an insulating lacquer coating, as there is sufficient Not always having earthing carried out.

Wie bereits erwähnt, hat das Hitzdrahtinstrument17 vorteilhaft eine in Zentimeter oder Millimeter geeichte Skala, um die Elektrodenspannung der Dicke des Werkstückes zwischen denElektroden anpassen zu können. Dies ist möglich, da das Hitzdrahtinstrument von der Spannung und der Frequenz an den Elektroden abhängig ist. Man braucht dann beim Verleimen eines Werkstückes von bestimmter Dicke bzw, bestimmter Leimfugenausdehnung lediglich die angelegte Spannung so einzuregeln, bis das Instrument den Wert der Werkstückdicke in Zentimeter bzw. Millimeter anzeigt. Die angelegte Spannung hat dann einen solchen Wert, daß die Verleimung bei der jeweils verwendeten Frequenz in einer bestimmten, durch die Skala des Instruments festgelegten Zeit abgeschlossen ist.As already mentioned, the hot wire instrument 17 advantageously has one Scale calibrated in centimeters or millimeters to determine the electrode voltage of the thickness of the workpiece between the electrodes. This is possible because the hot wire instrument depends on the voltage and frequency at the electrodes is. When gluing a workpiece of a certain thickness or certain glue joint expansion only to regulate the applied voltage in such a way that until the instrument shows the value of the workpiece thickness in centimeters or millimeters. The voltage applied then has such a value that the gluing at the respective used frequency in a certain, determined by the scale of the instrument Time is complete.

Das Gerät nach der Erfindung ist nicht an das in der Zeichnung dargestellte Ausführungsbeispiel gebunden, sondern kann in mannigfacher Weise abgewandelt werden. So können die Überwachungsmittel auch so eingerichtet sein, daß sie statt der zugeführten Wärmeleistung die zugeführte Wärmearbeit überwachen, indem sie beispielsweise die Zuführung der Wärmt nach Erreichen einer zweckmäßig einstellbaren Wärmearbeit selbsttätig abschalten. Ferner können Überwachungsmittel vorgesehen werden, die die Zuführung der Wärme nach Erreichen einer zweckmäßig einstellbaren Zeitspanne selbsttätig abschalten.The device according to the invention is not similar to that shown in the drawing Embodiment bound, but can be modified in many ways. So the monitoring means can also be set up so that they instead of the supplied Thermal output monitor the supplied thermal work by, for example, the The heat is supplied automatically after a suitably adjustable heat work has been achieved switch off. In addition, monitoring means can be provided to control the feed switch off the heat automatically after a suitably adjustable period of time has been reached.
