Description
Zum Besäumen von Bauholz wurden bisher allgemein übliche Gatter- oder Kreissägen zur Verwendung gebracht und sind von letzterer Art auch solche bekannt mit zwei in der glei-For trimming lumber, the usual gang saws or circular saws have been used so far Brought to use and are of the latter type also known with two in the same
.5 chen Schnittbahn wirkenden Sägeblättern, von welchen das eine von oben, das andere von unten wirkt und deren Achsen nicht senkrecht übereinander angeordnet sind. Derartige Sägen erlauben jedoch ein rasches Arbeiten nicht, sobald die Beanspruchung der einzelnen Blätter zu groß wird, bzw. richtet sich die Schnittgeschwindigkeit nach der Schnittiefe und der Härte des zu schneidenden Gegenstandes. Zudem müssen derartige Blätter sehr stark bzw. breit im Schnitt sein. Gemäß vorliegender Erfindung sind nun mehrere, in verschiedenen Höhenlagen derselben Schnittbahn wirkende, auf in ihrer Höhenlage verstellbar gelagerten Achsen, hintereinander und von der gleichen Seite aus in derselben Schnittbahn eingeführte Sägeblätter so vorgesehen, daß die Zerteilung des Arbeitsstückes, nicht wie bisher üblich durch Zerschneiden der Holzfasern senkrecht oder beinahe senkrecht zu diesen, sondern durch Ausheben derselben in oder beinahe in deren Längsrichtung· erfolgt..5 saw blades acting on the cutting path, one from above, the other from acts below and their axes are not arranged vertically one above the other. Such saws however, do not allow rapid work as soon as the stress on the individual Sheets become too large, or the cutting speed depends on the cutting depth and the hardness of the object to be cut. In addition, such sheets must be very be strong or broad in section. According to the present invention there are now several, in different heights of the same cutting path acting on adjustable in their height axles in bearings, saw blades inserted one behind the other and from the same side in the same cutting path are provided in such a way that that the division of the work piece, not as usual by cutting up the wood fibers perpendicular or almost perpendicular to them, but by digging them out takes place in or almost in their longitudinal direction.
Der Erfindungsgegenstand ist auf der beifolgenden Zeichnung in einem Ausführungsbei spiel dargestellt; es zeigt:The subject of the invention is shown in one embodiment in the following drawing game shown; it shows:
Fig. ι eine Seitenansicht desselben, Fig. 2 einen Grundriß zu Fig. 1 und Fig. 3 eine Seitenansicht zu Fig. 1.FIG. 1 is a side view of the same, FIG. 2 is a plan view of FIG. 1 and FIG. 3 is a Side view of FIG. 1.
Der das mittels Vorrichtungen 1 befestigte Arbeitsstück 2 tragende Wagen 3 ist mit diesem mittels Rollen 4 auf den Schienen 5 in seiner Längsrichtung verschiebbar. Seitlich der Bahn des Wagens sind in dem Gestell 6 die Wellen 7, 8, 9 drehbar gelagert, die mit Antriebsscheiben 10, 11, 12 versehen sind, welche ihren Antrieb von einer gemeinsamen auf der Zeichnung nicht dargestellten Welle aus erhalten. Auf der Welle 7 sind die Sägeblätter 13*, Ι3δ, auf der Welle 8 die Sägeblätter 14®, I46 und auf der Welle 9 die Sägeblätter 15°, 15* abnehmbar befestigt, wobei die Sägeblätter 13", 14°, 15" sowie 136, 14*, 156 je in einer und derselben Schnittebene liegen.The carriage 3 carrying the work piece 2 fastened by means of devices 1 can be displaced with it in its longitudinal direction by means of rollers 4 on the rails 5. To the side of the track of the carriage, the shafts 7, 8, 9 are rotatably mounted in the frame 6, which are provided with drive disks 10, 11, 12, which receive their drive from a common shaft, not shown in the drawing. On the shaft 7 the saw blades 13 *, Ι3 δ , on the shaft 8 the saw blades 14®, I4 6 and on the shaft 9 the saw blades 15 °, 15 * are detachably attached, the saw blades 13 ", 14 °, 15" and 13 6 , 14 *, 15 6 each lie in one and the same cutting plane.
An Stelle von je zwei nebeneinander liegenden Sägeblättern könnte auch je nur eines sowie auch mehr wie zwei solcher auf jeder Welle entsprechend angeordnet werden.Instead of two saw blades lying next to each other, only one could be used as well as more like two of these can be arranged accordingly on each shaft.
Die Verwendung der Kreissäge kann in der Weise geschehen, daß nach Befestigung des Baumstammes auf dem Wagen und nach dem Einrücken der Säge der Wagen in Richtung des Pfeiles α gegen die Sägeblätter verschoben wird. Dabei erfolgt zuerst der Schnitt mittels der Sägeblätter 13», 13s, hierauf, wennThe circular saw can be used in such a way that after the tree trunk has been attached to the carriage and after the saw has been engaged, the carriage is moved in the direction of arrow α against the saw blades. First, the cut is made by means of the saw blades 13 », 13 s , then, if
der Baumstamm in die Bahn der Sägeblätter 14", I46 gelangt, der Schnitt durch diese und später der Schnitt durch die Sägeblätter 15*, ΐ5δ, die in den Schnitten der Sägeblätter 13"·, 13s geführt sind und eine Verbindung herstellen zwischen diesen Schnitten und den Schnitten der Sägeblätter 14", I46.the tree trunk enters the path of the saw blades 14 ″, I4 6 , the cut through these and later the cut through the saw blades 15 *, ΐ5 δ , which are guided in the cuts of the saw blades 13 ″, 13 s and establish a connection between these cuts and the cuts of the saw blades 14 ″, I4 6 .
Es ist auch vorgesehen, die Lager, in welchen die Wellen 7, 8, 9 gelagert sind, in ihrer, .Höhenlage verstellbar anzuordnen, zum Zwecke, die Schnittbreiten der Sägeblätter verändern zu können bzw. bei Abnutzung der Sägeblätter infolge N achschärf ens solche nachstellen zu können.It is also provided that the bearings in which the shafts 7, 8, 9 are mounted, in their, . To arrange the height adjustable, for the purpose of the cutting widths of the saw blades to be able to change or if the saw blades wear out as a result of resharpening to be able to adjust.
