Abstract
Description
Den Trapezlamellenproduktionen geht eine Rundholzeinschnittweise voraus, die in der Holzbranche als Sternsägen bezeichnet wird. In der Praxis können die Einzelstücke in verschiedensten Arten plaziert werden, und die Einschnittmerkmale der Rundholzzerlegungen sind - einschl. der eingesetzten Sägemaschinen mit den Werkstückführungen - hinreichend bekannt. The trapezoidal lamella production is preceded by a round cut, which is called star saws in the wood industry. In practice you can the individual pieces are placed in different ways, and the Cutting characteristics of the log cutting are - including the ones used Sawing machines with the workpiece guides - well known.
Die in Rundholzabschnitten "praktisch nie" mittig plazierten Kernholzbereiche und die "praktisch nie" kreisrunden Rohholzformen führen - ganz gleich, welche Segmentarten vorgeschnitten werden - immer zu Ausbeute- und Qualitätsproblemen. The "practically never" placed in the middle of logs Heartwood areas and the "practically never" circular raw wood shapes lead - quite no matter which segment types are pre-cut - always to yield and quality problems.
In der DE 101 61 024 werden Methoden zur flexiblen Anpassung durch asymmetrische Teilungen (4) beschrieben, und die DE 102 00 335 zeigt Methoden zur Qualitätssteigerung durch Faserparallelitäten (5). DE 101 61 024 describes methods for flexible adaptation by means of asymmetrical divisions ( 4 ), and DE 102 00 335 shows methods for increasing quality through fiber parallelism ( 5 ).
Spezifische Einrichtungen für den Zuschnitt der dreieckähnlichen Rohlamellen (7) und deren Besäumungen/Profilierungen - unter Beachtung der Schenkellage (13) zu den Besäumlinien für verschiedene Rasterbreiten (14) und den dazu verschiedenen Parallelseiten (15) - sind nicht bekannt. Specific devices for cutting the triangular-like raw slats ( 7 ) and their trimming / profiling - taking into account the leg position ( 13 ) for the trimming lines for different grid widths ( 14 ) and the different parallel sides ( 15 ) - are not known.
Erfindunginvention
Weil aufgrund der unterschiedlichsten Holzformen und der Kernbereichsunregelmäßigkeiten (Fig. 1) die verschiedensten Segmentarten (6) mit gegeneinander abweichenden Mittelsenkrechten entstehen, wird die Werkstück- bzw. Segmentführung zur Rohlamellenaufteilung nicht in Orientierung an Spitzen (16) oder Baumflächen (17) vorgenommen, sondern erfindungsgemäß durch eine Werkstückführung (8), deren Gradzahl der Gradzahlsumme aller Einzel-Rohlamellen entspricht; und die Werkstückführung (8) ist - zur Setzung asymmetrischer Plazierungen - seitlich verschiebbar (10). Because due to the different wood shapes and the core area irregularities ( Fig. 1) the most diverse segment types ( 6 ) with mutually deviating perpendiculars are created, the workpiece or segment guidance for the raw lamella division is not carried out in orientation at the tips ( 16 ) or tree areas ( 17 ), but according to the invention by means of a workpiece guide ( 8 ), the number of degrees of which corresponds to the total number of degrees of all individual raw lamellae; and the workpiece guide ( 8 ) is laterally displaceable ( 10 ) for the placement of asymmetrical positions.
Weil der Trapezlamellenbalken (1) aus einzelnen Trapezlamellensträngen (3) besteht und die einzelnen Trapezlamellen (2) eines Stranges keine unterschiedlichen Querschnittformen aufweisen dürfen, wird die notwendige geometrische Zuordnung erfindungsgemäß dadurch gelöst, dass die Rohlamellen (7) vor Besäumung (11) unter einer Gradzahlführung (12) fixiert werden, und demzufolge die Besäumung (11) für die Rasterbreiten (14) gleichgroße Schenkelgeometrien (13) innerhalb einer Trapezlamelle (2) erzeugt. Because the trapezoidal lamella beam ( 1 ) consists of individual trapezoidal lamella strands ( 3 ) and the individual trapezoidal lamellae ( 2 ) of a strand may not have different cross-sectional shapes, the necessary geometric assignment is achieved according to the invention in that the raw lamellae ( 7 ) before trimming ( 11 ) under one Degree guide ( 12 ) are fixed, and consequently the trimming ( 11 ) for the grid widths ( 14 ) produces leg geometries ( 13 ) of the same size within a trapezoidal lamella ( 2 ).
Fig. 1 zeigt die in der Praxis unterschiedlichst entstehenden Segmente (6). Fig. 1 shows the resulting segments A diversity in practice (6).
Fig. 2 zeigt die Darstellung der Primärpositionen = Trapezlamelle (2), Trapezlamellenstrang (3) und Trapezlamellenbalken (1). Fig. 2 shows the representation of the primary positions = trapezoidal lamella ( 2 ), trapezoidal lamella strand ( 3 ) and trapezoidal lamella bar ( 1 ).
Fig. 3 zeigt die symmetrische und asymmetrische Aufteilung von Segmenten (6) zu Rohlamellen (7). Fig. 3 shows the symmetrical and asymmetrical division of segments ( 6 ) to raw lamellae ( 7 ).
Fig. 4 zeigt die Folge der Besäumung/Profilierung(11) von Rohlamellen (7)
zu Trapezlamellen (2) mit den Schritten:
- - Rohlamelle (7) einschieben (18) und unter Gradzahlführung (12) fixieren,
- - Rohlamelle (7) vermessen (19),
- - Sägewerkzeuge (20) positionieren und Rohlamelle (7) besäumen/profilieren (11 bzw. 14).
- - Insert the raw lamella ( 7 ) ( 18 ) and fix it under the number guide ( 12 ),
- - Measure the raw lamella ( 7 ) ( 19 ),
- - Position the sawing tools ( 20 ) and trim / profile the raw lamella ( 7 ) ( 11 or 14 ).
