Abstract

Eine Vorrichtung (1) dient zum Bearbeiten von hölzernen Werkstücken (2), nämlich von Baumstämmen oder Modeln, an vier winklig oder rechtwinklig zueinander angeordneten oder wenigstens zwei parallel zueinander angeordneten Längsseiten und weist dazu eine Bearbeitungsstation (3) auf, in welcher Werkzeuge (4), wie Zerspaner, Fräser und/oder Sägeblätter (7) zum Bearbeiten des hölzernen Werkstückes (2) während seines Vorschubes angeordnet sind. Zu der Vorrichtung (1) gehört eine Zuführeinrichtung (5), die für den Vorschub des Werkstückes (2) zu der und in die Bearbeitungsstation (3) sorgt, wobei das Werkstück (2) in seiner Längserstreckungsrichtung und in Richtung seiner Längsmittelachse (9) bewegbar ist. Die Zuführeinrichtung (5) weist dazu wenigstens zwei in Vorschubrichtung hintereinander angeordnete und in Vorschubrichtung zumindest während des ersten Teils des Vorschubes synchron bewegbare Greifer (10, 11) auf. Für eine automatisierte Ausrichtung und Bearbeitung kann in Vorschubrichtung vor dieser Zuführeinrichtung (5) oder zumindest an deren Anfang eine Messvorrichtung (12) zur Ermittlung der Abmessungen und/oder der Form des jeweiligen Werkstückes (2) vorgesehen sein, die die beiden Greifer (10, 11) und Ausrichtmittel ansteuert, um das Werkstück (2) in optimaler Lage erfassen und bearbeiten zu können (Fig. 3).

A device (1) is used for processing wooden workpieces (2), namely logs or models, arranged at four angles or at right angles to each other or at least two parallel longitudinal sides and has for this purpose a processing station (3), in which tools (4 ), such as chipper, cutter and / or saw blades (7) are arranged for processing the wooden workpiece (2) during its feed. To the device (1) includes a feeding device (5), which provides for the advance of the workpiece (2) to and in the processing station (3), wherein the workpiece (2) in its longitudinal direction and in the direction of its longitudinal central axis (9) is movable. For this purpose, the feed device (5) has at least two grippers (10, 11) arranged one behind the other in the feed direction and synchronously movable in the feed direction, at least during the first part of the feed. For automated alignment and machining, a measuring device (12) for determining the dimensions and / or the shape of the respective workpiece (2) can be provided in the feed direction in front of this feed device (5) or at least at the beginning thereof, the two grippers (10, 11) and aligning means in order to be able to grasp and process the workpiece (2) in an optimal position (FIG. 3).
