Description

Vorrichtung zum Reinigen gebrauchter Schalungsbretter. Die vorliegende Erfindung betrifft eine Vorrichtung zur Beseitigung der Zementkrusten an benutzten Schalungsbrettern.Device for cleaning used shuttering boards. The present The invention relates to a device for removing the cement crusts used Shuttering boards.

In bekannter Weise werden die Schalungsbretter zwischen Vorschubwalzen hindurchbewegt, welche jedoch außer der Vorschubbewegung auch die anhängenden Mörtelreste möglichst abquetschen sollen. Um diesen Zweck zu erreichen, werden bei der vorliegenden Erfindung die Umfangsgeschwindigkeiten zweier geriffelter oder gezahnter V orschubwalzen, die sich auf der zu reinigenden Seite der Schalbretter befinden, verschieden groß gemacht, so daß die Zähne mindestens einer Walze auf der Oberfläche des Schalbrettes gleiten müssen und außer der quetschenden, eine schabende Wirkung hervorbringen. Um trotzdem einen gleichmäßigen Vorschub der Bretter zu erreichen, kann die Gegendruckwalze nahe an eine der beiden Vorschubwalzen herangerückt werden, so daß deren Umfangsgeschwindigkeit die Vorschubgeschwindigkeit der Bretter im wesentlichen bestimmt. Nach dem Durchgang durch die Vorschubwa1zen werden die Bretter durch Schlagkörper abgeklopft, die auf einer kreisenden Trommel in einer Schraubenlinie angeordnet und mit der Trommel gelenkig, federnd oder mittels elastischer Zwischenglieder verbunden sind. ` Durch Erhöhung der Umdrehzahl der Trommel kann die Dichte der Aufschlagpunkte vergrößert werden und unter der Wirkung der Fliehkraft die Stärke der einzelnen Schläge, was übrigens auch durch Veränderung des Abstandes der Trommelachse von der zu klopfenden Oberfläche der Bretter zu erreichen ist.In a known manner, the shuttering boards are between feed rollers moves through it, which, however, in addition to the feed movement, also the attached mortar residues should squeeze as much as possible. In order to achieve this purpose, the present Invention the peripheral speeds of two corrugated or toothed feed rollers, which are located on the side of the shuttering boards to be cleaned, of different sizes made so that the teeth of at least one roller on the surface of the shuttering board have to slide and, in addition to the squeezing effect, produce a scraping effect. In order to achieve an even feed of the boards in spite of this, the counter-pressure roller can be moved close to one of the two feed rollers, so that their peripheral speed the speed of advance of the boards is essentially determined. After the passage By means of the feed rollers, the boards are knocked off by striking bodies that open a rotating drum in a helical line arranged and with the drum articulated, resilient or connected by means of elastic intermediate links are. `By increasing the speed of rotation of the drum, the density of the points of impact be enlarged and under the action of centrifugal force the strength of each Beats, which incidentally also by changing the distance of the drum axis from the surface of the boards to be tapped can be reached.

Auf diese Weise wird durch die quetschenden und schabenden Vorschubwalzen die Oberfläche der Schalbretter im wesentlichen von anhaftendem erhärteten Betonmörtel befreit und die noch anhaftenden Reste durch die Klopfer gelockert, so daß ein Nachputzen in bekannter Weise durch hin und hergehende oder kreisende Schabereinrichtungen oder Bürsten zu einer vollkommenen Beseitigung der Betonreste führt.In this way, the crushing and scraping feed rollers the surface of the shuttering boards essentially from adhering hardened concrete mortar freed and the still adhering residues loosened by the knocker, so that a re-cleaning in a known manner by reciprocating or rotating scraper devices or brushing leads to a complete removal of the concrete residue.

Eine Ausführungsform ist in ihren wesentlichen Teilen in Abb. r im Längsschnitt, in Abb.2 im Grundriß dargestellt. Ein Schalbrett a wird durch die in einem geeignetien Maschinengestell gelagerten angetriebenen Vorschubwalzen b und c gegen die unter Federdruck stehende Walze d ,gepreßt und durch die Maschine hindurchgeschoben. Die Walzen b und c drehen sich mit etwas voneinander abweichender Geschwindigkeit. Auf einer kreisenden Trommel k sind in einer Schraubenlinie die Klopfkörper L angeordnet, die gegen die untere Fläche des zu reinigenden Schalbrettes schlagen. Nach dem Vorbeigang an diesen Klopfern findet in bekannter Weise durch Schaber oder Bürsten eine Nachreinigung der Oberfläche der Schalbretter statt, wobei die noch etwa an der Holzfaser hängenden Betonteilchen beseitigt werden.An embodiment is shown in its essential parts in Fig Longitudinal section, shown in plan in Fig. A cladding board a is through the Driven feed rollers mounted in a suitable machine frame b and c against the spring loaded roller d, pressed and through the machine pushed through. The rollers b and c rotate slightly different from each other Speed. On a rotating drum k are in a helix the Knocking body L arranged against the lower surface of the cladding board to be cleaned beat. After passing this knocker takes place in a known manner Scrapers or brushes are used to clean the surface of the shuttering boards the concrete particles still hanging on the wood fiber are removed.
