Description
Beim Erhitzen von Gut im elektrischen Kondensatorwechselfeld, beispielsweise beim Verleimen oder Verkleben, ergeben sich Schwierigkeiten, wenn das: Gut und die ihm angepaßten Feldelektroden ehre große Länge aufweisen. In. einem solchen Fall wirkt die lange Kondensatorleitung als Lecher-System, und die Spannungen an den einzelnen Ab- schnitten der Kondensatorleitung weisen eine unterschiedliche Größe auf. Beim Verleimen von Gutteilen miteinander, z. B. bei der Herstellung von Holmgurten aus einzelnen Lamellen, treten dann an den. verschiedenen Gutstellen in Abhängigkeit von den unterschiedlichen Spannungen in den einzelnen Feldabschnittern Temperaturunterschiede auf, die nicht tragbar sind. Für eine einwandfreie Verleimung muß man aber fordern, daß an allen Gutteilen bzw. in deren Leimfugen überall die gleichen Temperaturen vorherrschen oder daß zum mindesten größere Temperaturunterschiede vermieden werden.When heating goods in the alternating electric capacitor field, for example when gluing or gluing, difficulties arise if the goods and the field electrodes adapted to them are of great length. In. In such a case, the long capacitor line acts as a Lecher system, and the voltages on the individual sections of the capacitor line are of different magnitudes. When gluing good parts together, z. B. in the production of spar chords from individual slats, then occur on the. different good points depending on the different voltages in the individual field sections on temperature differences that are not acceptable. For a perfect gluing, however, one must demand that the same temperatures prevail everywhere on all good parts or in their glue joints or that at least larger temperature differences are avoided.
Es ist bereits vorgeschlagen worden, wenigstens eine der beiden Feldelektroden in Einzelelektroden aufzuteilen. Durch diese Maßnahme erhält man die Möglichkeit, die Peldstärkenverhältnisse im Gut zu beeinflussen.It has already been proposed to use at least one of the two field electrodes to be divided into individual electrodes. This measure gives you the opportunity to To influence the field strength ratios in the property.
Erfindungsgemäß ist zur Homogenisierung des sich zwischen den Feldelektroden. ausbildenden Feldes der Abstand. jeder Einzelelektrode oder einer Gruppe von Einzelelektroden zum Gut veränderbar.According to the invention is to homogenize the between the field electrodes. training field the distance. each individual electrode or a group of individual electrodes changeable to the good.
Für die Abstandsänderung der Einzelelektroden vom Gut ergeben sich verschiedene Möglichkeiten. So kann die Halterung einer z. B. verschwenkbar angeordneten Einzelelektrode in Richtung zum Gut veränderbar gemacht werden, oder die Elektroden selbst können in Führungsrillen gehaltert sein, die verschiedenen Abstand vom Gut haben und, deren Anzahl den Erfordernissen des Betriebes angepaßt ist: Eine beispielsweise Ausführungsform der Erfindung wird. an Hand der Zeichnung näher erläutert. In Fig. i ist das Gut i, z. B. ein aus mehreren Lamellen 2 zu verleimender Holmgurt großer Länge, zwischen der festen Elektrode 3 und der veränderbaren Elektrode q. angeordnet. Der Abstand der Elektrode ,¢ von dem Gut i -ist veränderbar. Hierbei ist die Elektrode q. in Führungsnuten 5 des Arbeitstisches einschiebbar. Die Fig.2 zeie die Elektrodenanordnung von der Seite und von oben. Die Bezugszeichen sind entsprechend denen. der Fig. i gewählt. Aus der Figur ist zu erkennen:, da,ß der Abstand der drei dargestellten Elelctrodern q., q.' und q" vom Gut i je .ein anderer ist. Hierdurch lassen sich Feldstärkenunterschiede in verhältnismäßig einfacher Weise ausgleichen.For the change in the distance between the individual electrodes and the product, various possibilities. So the holder of a z. B. pivotably arranged Individual electrode can be made changeable in the direction of the good, or the electrodes themselves can be held in guide grooves, the different distances from the goods have and whose number is adapted to the requirements of the company: One for example Embodiment of the invention is. explained in more detail with reference to the drawing. In Fig. i is the good i, e.g. B. one of several slats 2 to be glued spar belt large Length between the fixed electrode 3 and the variable electrode q. arranged. The distance between the electrode ¢ and the good i -is changeable. Here is the electrode q. can be inserted into guide grooves 5 of the work table. Fig.2 shows the electrode arrangement from the side and from above. The reference numbers correspond to those. of Fig. i elected. From the figure it can be seen:, da, ß the distance between the three shown Elelctrodern q., Q. ' and q "of the good i each. is another Compensate for field strength differences in a relatively simple manner.
Die Elektrode 3 ist zwar als feste Elektrode dargestellt, es ist jedoch auch möglich, daß bei beson,deren betrieblichen Erfordernissen auch diese Elektrode so gestaltet sein kann, daß auch ihr Abstand zum Gut veränderbar ist.The electrode 3 is shown as a fixed electrode, but it is also possible that with special, their operational requirements also this electrode can be designed so that their distance to the property can be changed.
Es ist auch möglich; .die Elektrode 3 ebenfalls in Einzelelektroden aufzuteilen, um bei besonders schwierigen Betriebsverhältnissen- eine einwandfreie Feldhomogenisierung zu erreichen.It is also possible; . The electrode 3 also in individual electrodes to be divided in order to obtain a faultless one in particularly difficult operating conditions To achieve field homogenization.
Die Erfindung ist in Holz verarbeitenden Betrieben., insbesondere in Möbeltischlereien, Bootsbaubetrieben und bei der Flugzeugherstellung anwendbar:The invention is in wood processing plants., In particular Applicable in cabinet makers, boat builders and aircraft manufacturing:
