Abstract
Holzbearbeitungsmaschine mit Hauptsäge- und Vorritzsägeblatt und einem Bearbeitungstisch mit Tischeinlegeleisten, dadurch gekennzeichnet, dass die Tischeinlegeleiste durch eine besondere, von der Umgebung deutlich unterscheidbare, Farbgebung und Beleuchtung den Gefahrenbereich des Vorritzsägeblattes besonders hervorhebt.Woodworking machine with main saw and scoring saw blade and a processing table with Tischeinlegeleisten, characterized in that the Tischeinlegeleiste by a special, clearly distinguishable from the environment, color and lighting the danger zone of the scoring saw blade particularly emphasizes.
Description
Vorritzsägeblätter in Holzbearbeitungsmaschinen, insbesondere in Formatkreissägen, weisen ein Gefährdungspotential für den Bediener und auch für das Werkstück auf, da sie auf Grund ihres geringen Sägeblattüberstandes über die Bearbeitungsebene und bedingt durch eine Drehzahl von 8000 1/min oder höher, kaum erkennbar sind. Dadurch ist beim Verschieben des Werkstückes in eine Bearbeitungsposition eine Beschädigung der Oberfläche möglich. Außerdem können beim Entfernen von Spänen oder Werkstückabschnitten Handverletzungen auftreten. In der Regel wird durch einen leuchtenden Drucktaster signalisiert, dass die Vorritzsäge eingeschaltet ist. Diese Signalisierung ist oft nicht ausreichend, da der leuchtende Drucktaster nicht erkennbar ist, wenn er z. B. durch das Werkstück verdeckt wird.Scoring saw blades in Woodworking machines, especially in sliding table saws, have a risk potential for the Operator and also for the workpiece because they due to their small saw blade projection on the working plane and due to a speed of 8000 1 / min or higher, hardly are recognizable. This is when moving the workpiece in a machining position, damage to the surface possible. In addition, at Removing chips or workpiece sections Hand injuries occur. As a rule, it is illuminated by a pushbutton signals that the scoring saw is turned on. This signaling is often not sufficient because the illuminated push-button is not recognizable when he z. B. through the workpiece is covered.
Eine Verbesserung der Situation wird dadurch erreicht, dass zum Einen der Gefahrenbereich durch eine farbige Tischeinlage gekennzeichnet wird und zum Anderen die Tischeinlage bei eingeschaltetem Vorritzsägeblatt, durch integrierte Leuchtmittel, leuchtet.A Improvement of the situation is achieved by, on the one hand the danger zone is marked by a colored table insert and on the other hand the table insert with the scoring saw blade switched on, through integrated bulbs, lights.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, den Gefahrenbereich des Vorritzsägeblattes am Arbeitstisch deutlich kenntlich zu machen um so mögliche Gefährdungen des Bedieners zu verhindern.Of the in claim 1 protection invention is based on the problem the danger zone of the scoring saw blade clearly marked on the worktable so possible hazards to prevent the operator.
Weiterhin ist es hilfreich, bei auf dem Werkstück markierten Schnittlinien, wenn die Schnittlinie vor den Sägeblättern in der Tischeinlage erkennbar ist und das Werkstück hiernach ausgerichtet werden kann. Durch die Markierung der Schnittlinie wird dem Bediener das Positionieren der Werkstücke erleichtert, wenn Schnitte ohne Benutzung eines Anschlags durchgeführt werden.Farther it is helpful to use cutting lines marked on the workpiece, when the cutting line in front of the saw blades in the table insert is recognizable and the workpiece can be aligned thereafter. Marking the cut line will position the operator the workpieces facilitates when cuts are made without using a stop.
Dieses Problem wird mit den im Schutzanspruch 7 aufgeführten Merkmalen gelöst.This Problem is solved with the features listed in the protection claim 7.
