Description

„Den Gegenstand der Erfindung,bildet eine Bandsäge mit einer Vorschubrolle zum Herstellen von geschweiften Hölzern, bei der die • Vorschubrolle in Richtung der Schweifung gesteuert und das Werkstück sicher geführt wird."The subject of the invention is a band saw with a feed roller for manufacturing of curly woods where the • feed roller in the direction of the curvature controlled and the workpiece is safely guided.

In der Zeichnung ist der Erfindungsgegenstand in der Abb. 1 schaubildlich, in der • Abb. 2 in Draufsicht dargestellt, während die ίο Abb. 3 eine andere Ausführung zeigt. 'In the drawing, the subject of the invention is shown diagrammatically in Fig. 1, in which • Fig. 2 shown in plan view, while the ίο Fig. 3 shows a different version. '

Die Bandsäge hat den Zweck, die Führung und den Vorschub von Menschenhand unnötig zu machen, außerdem das Aufzeichnen der einzelnen Modelle zu ersparen. Es sind Bandsägen bekannt, die mit automatischem Vorschub ausgerüstet, sind (für gerade Schnitte), die sogenannten Trennbandsägen. Die vorliegende Erfindung, stellt etwas wesentlich Neues dar, da mit dieser Maschine nicht nur gerade Hölzer, sondern- jede beliebige Schweifung, hohl, gebogen und S-förmig, hergestellt werden kann.The band saw has the purpose of unnecessary human guidance and advancement to make, also to save the recording of the individual models. There are band saws that are equipped with automatic feed (for straight cuts), the so-called band resaws. The present invention represents something essentially new, since with this machine not only straight pieces of wood, but - any one Curve, hollow, curved and S-shaped, can be made.

Das Wesentliche dieser Erfindung stellt dieThe essence of this invention provides the

lenkbare Vorschubrolle 9 dar, die in Verbin-steerable feed roller 9, which in connection

25' dung mit der Anlaufscheibe 10, AnlaufzarJfen 11 und Lenkzapfen 12 modellgerechten Schnitt gewährleistet.25 'connection with the thrust washer 10, start-up teeth 11 and steering pin 12 model-appropriate cut guaranteed.

Der Antrieb wird von der unteren Sägewelle von Zahnrad ι auf Zahnrad 2,' weiter von Zahnrad 3 auf Zahnrad 4 übertragen.The drive is from the lower saw shaft from gear ι to gear 2, 'on Transfer from gear 3 to gear 4.

Mit Zahnrad 4 ist ein Tellerrad verbunden, welches verschiedene Zahnkränze trägt, in diese greift das durch Segmenthebel'6 verstellbare Stirnrad 5 und läßt "verschiedene Geschwindigkeiten zu. Weiter erfolgt der Antrieb durch vier Kegelräder auf die Welle 7, welche durch ein doppeltes Kardangelenk 8 oder biegsame Welle wendig ist. Diese trägt am Ende die eigentliche Vorschubrolle 9 und mit kleinem Abstand eine*" löse Laufrolle 9". . 'With gear 4, a ring gear is connected, which carries various ring gears, in this engages the adjustable by segment lever'6 Spur gear 5 and allows "different speeds. The Drive by four bevel gears on the shaft 7, which by a double universal joint 8 or flexible shaft is manoeuvrable. At the end, this carries the actual feed roller 9 and with a small distance a * "loosen roller 9". . '

Der Vorschub des Holzes erfolgt etwas schräg zur Säge und wird dadurch an die zur Säge ' fein- einstellbare Anjauf scheibe 10 und Anlaufzapfen Ii gedrückt; selbiger führt in einem Schlitz die Säge, die beiden letzteren überragen um Modelldickte etwa 1 cm. Der Lenkzapfen 12 tastet die kommende Schnittrich tung ab und wird bei hohlem Modell die Richtungsschräge der Vorschubrolle zur Säge abschwächen, dagegen bei krummen Holz dieselbe verstärken. Dadurch werden Klemmungen und nicht genügender Modellandruck vermieden. Der Schwenkpunkt der Vorschubrolle liegt in dieser'selbst. Ein weiteres Führungslager ist in einem Schlitz gegen eine Druckfeder 13 gelagert.The wood is fed at a slight angle to the saw and is thereby attached to the finely adjustable Anjauf disk 10 and the thrust pin Ii pressed; the same leads the saw in a slot, the latter two protruding around model thickness about 1 cm. The steering pin 12 feels the coming cutting line The directional slope of the feed roller becomes a saw in the case of a hollow model weaken it, but strengthen it with crooked wood. This causes clamps and insufficient model pressure avoided. The pivot point of the feed roller lies in this itself. Another guide bearing is in a slot against a compression spring 13 stored.

Der Andruck von oben geschieht durch eine Federdruckrolle 15, welche am Rollenführungsstutzen 16 befestigt ist. ' The pressure from above is done by a spring pressure roller 15 which is attached to the roller guide support 16. '

Die Stellschraube 14 ermöglicht eine Verstellung der Vorschubschräge. -The adjusting screw 14 enables adjustment the feed slope. -

Abb. 3 stellt die Vorrichtung in etwas einfacherer Ausführung dar, wie dieselbe für leichtere" Maschinen geeignet ist.Fig. 3 shows the device in a somewhat simpler design than the same for lighter "machines is suitable.

Der Antrieb wird in diesem Falle von einer gerillten Tellerscheibe 17 durch ein Stirnrad 18 auf die biegsame Welle 19 übertragen, welche in eine feste Welle 20, die zweimal 'bei 21 · gelagert ist, übergeht. "The drive is in this case of a grooved plate washer 17 through a Spur gear 18 transferred to the flexible shaft 19, which in a fixed shaft 20, the is stored twice 'at 21 · passes. "

Das Ende der Welle 20 tragt die Vorschubrolle 9, welche in einer Gabel läuft, die in den Lenkzapfen 12 ausläuft.The end of the shaft 20 carries the feed roller 9, which runs in a fork which ends in the steering pivot 12.

Anlauf scheibe ία, Anlaufzapfen 11, Druckrolle 15, wie auch die Arbeitsweise bleiben dieselben wie bei Abb. 2. Für scharfkurvige Sachen ist ein zweiter Anlaufzapfen 22 vorgesehen, welcher etwa 8 bis 10 mm Abstand vom anderen Anlauf zapf en hat; dieser führt dann in einer Nut des Modells. Bei ziem-Hch' parallel geschweiften Modellen kommt eine oder mehrere Andrückscheiben 23, zur Anwendung, welche in einem Schlitz anfedern. .Thrust washer ία, thrust pin 11, pressure roller 15, as well as the mode of operation, remain the same as in Fig. 2. For sharp turns Things a second run-up pin 22 is provided, which is about 8 to 10 mm apart has drawn from the other approach; this then leads in a groove in the model. By pretty much parallel curved models comes one or more pressure washers 23, for Application which spring in a slot. .
