Description

Beim Anleimen von Rippen . und Spanten an Holmen im 'elektrischen Wechselfeld müssen die Feldelektroden nach Möglichkeit so zueinander angeordnet werden, daß sich das zwischen ihnen ausbildende Feld über die Leimfugen verläuft. Beim Anleimen einer großen Zahl von Rippen oder Spänten an Halmen großer Länge ist es umständlich und zeitraubend, nach Fertigstellung eines Gutkörpers die Feldelektroden aus- und bei der Behandlung eines neuen Werkstückes in dieses wieder einzubauen. Dieser Nachteil tritt besonders dann in Erscheinung, wenn man zur Zeitersparnis jeweils mehrere- Stellen des Gutes gleichzeitig erwärmen bzw. verleimen will und hierzu mehrere Wechselfelder mit je besonderen Feldelektroden gleichzeitig, anwenden will.When gluing ribs. and frames on spars in the 'electric Alternating field, the field electrodes must be arranged in relation to one another as far as possible that the field forming between them runs over the glue joints. When gluing a large number of ribs or shavings to stalks of great length it is cumbersome and time-consuming to use the field electrodes after a good body has been completed dismantling and re-installing it when treating a new workpiece. This disadvantage is particularly evident when looking to save time want to heat or glue several points of the goods at the same time and to do this, use several alternating fields at the same time, each with special field electrodes want.

Gemäß der Erfindung werden mindestens - die gleichpoligen Feldelektroden der verschiedenen Wechselfelder oder eine Gruppe von -ihnen zu einer an das Gut anlegbaren Baueinheit zusammengefaßt.According to the invention, at least - the homopolar field electrodes of the various alternating fields or a group of them to one attached to the good Applicable structural unit summarized.

Durch die Erfindung ergibt sich der Vorteil, daß bei der Erhitzung bzw. Verleimung großer Stückzahlen von Gutkörpern oder Gutkörperstellen ein rasches Auswechseln der Elektroden möglich ist und sich .dadurch eine erhebliche Zeitersparnis erzielen läßt.The invention has the advantage that when heated or gluing of large numbers of good bodies or good body locations a quick Replacing the electrodes is possible and this saves a considerable amount of time can achieve.

Es können erfindungsgemäß so@wahlKondensatorfeldelektroden als auch Spulernfeldelektroden oder beide Elektrodenarten gemischt zu einer Baueinheit zusammengefaßt werden.According to the invention, electrolytic capacitor field electrodes can be used as well Spool learning field electrodes or both types of electrodes mixed together to form a structural unit will.

Vorteilhaft werden die Elektroden durch metallische oder nichtmetallische Abstandhalter miteinander verbunden, die die eindeutige Lage der Elektroden zueinander und zum Gut, beispielsweise zu den Leimfugen des Gutes, festlegen.The electrodes are advantageous if they are metallic or non-metallic Spacers connected to one another, which clearly define the position of the electrodes to one another and to the good, for example to the glue joints of the good.

Besonders vorteilhaft ist es, sämtliche Elektroden an einem gemeinsamen Tragseil anzubringen und die- Elektroden zusammen mit ihrem Traggestell beim Auswechseln der Gutkörper so zu verschwenken, verdrehen, heben oder senken oder sonstwie bewegen, daß sie beim Auswechseln der Gutteile nichtstörend im Wege stehen.It is particularly advantageous to have all electrodes on a common Attach the support cable and the electrodes together with their support frame when replacing to swivel, twist, raise or lower the good body or move it in any other way, that they do not get in the way of changing the good parts.

Beim Anwenden der Einrichtung nach der Erfindung kann es vorkommen, daß es durch die Form des Gutes und der Baueinheit unmöglich ist, die Baueinheit nach erfolgter Verleimung wieder vom Gut zu entfernen. In manchen Fällen wird es durchaus nicht störend sein, wenn dann die Baueinheit an dem Gut verbleibt. Den Verlust der Baueinheit wird man oft angesichts der erzielten Arbeitsvereinfachung in Kauf nehmen können. In anderen Fällen kann aber die im Gut verbleibende Baueinheit sogar zur Versteifung oder Materialersparnis des -Gutes beitragen und eigens hierfür ausgebildet sein.When using the device according to the invention it can happen that it is impossible due to the shape of the goods and the structural unit, the structural unit to be removed from the goods after gluing. In some cases it will not be at all disturbing if the structural unit then remains on the property. The One will often lose the structural unit in view of the simplification of work achieved can accept. In other cases, however, the structural unit remaining in the good even contribute to the stiffening or material savings of the goods and especially for this be trained.

Die Erfindung wird an Hand einer Figur näher erläutert. An den Holmen i und 2 sollen Rippen 3 angeleimt werden. In dem Raum zwischen den Rippen 3. und den Holmen i und 2 sind die Feldelektroden 4 angeordnet. Durch Abstandhalter 5 wird die eindeutige Lage der Elektroden ¢ zueinander und zu dem Gutteil i bis 3 gesichert. Die Elektroden ¢ sind an ihren Enden winklig aasgebogen, um eine möglichst hohe Feldstärke in den einzelnen Leimfugen zwischen den Rippen 3 und den Holmen i und 2 zu erzielen.The invention is explained in more detail with reference to a figure. On the spars i and 2 ribs 3 are to be glued on. In the space between the ribs 3. and The field electrodes 4 are arranged on the spars i and 2. By spacer 5 is the clear position of the electrodes ¢ to each other and to the good part i to 3 secured. The ends of the electrodes are bent at an angle to be as high as possible Field strength in the individual glue joints between the ribs 3 and the spars i and 2 to achieve.

Die Erfindung ist vorzugsweise in holzverarbeitenden Betrieben anwendbar, z. B. in Möbeltischlereien, in Bootsbaubetrieben und bei der Flugzeugherstellung.The invention is preferably applicable in wood processing companies, z. B. in cabinet makers, boat builders and aircraft manufacturing.
