Description

Gegenstand der Erfindung ist eine Spannvorrichtung für Holzscheite an einer Holzsägemaschine mit Schrägaufzug, welche die Scheite, während sie mittels Transportketten schräg nach aufwärts befördert werden, in mehrere Stücke schneidet.The invention relates to a clamping device for logs on a wood sawing machine with an inclined lift, which cuts the logs while they are by means of Transport chains are conveyed diagonally upwards, cuts into several pieces.

Nach der Erfindung sind die Spannvorrichtungen federbelastete Greifer, wobei jedes Stück der Scheite durch einen Greifer so lange festgehalten wird, bis seine Klemmwirkung beim Überlaufen der Kettet über die obersten Kettenräder und durch das Gewicht der Stücke aufgehoben und diese, z. B. in ein untergestelltes Transportfahrzeug, fallen.According to the invention, the clamping devices are spring-loaded grippers, each piece of the billets being held by a gripper until its clamping effect when the chain overflows over the top sprockets and lifted by the weight of the pieces and these, z. B. in a subordinate Transport vehicle, fall.

Fig. i zeigt eine Seitenansicht des unteren Teiles der Holzsägemaschine, an der die Spannvorrichtungen angebracht sind; Fig. 2 und 3 zeigen eine Vorderansicht bzw. einen Grundriß einer Spannvorrichtung nach der I3rfindung.Fig. I shows a side view of the lower part of the wood sawing machine, to which the tensioning devices are attached; Figs. 2 and 3 show a front view or a plan view of a clamping device according to the invention.

D e n sich längs der Arbeitsi - Holzscheite bewe,e fläche 3 der Holzsägemaschine schräg nach aufwärts. Längs dieser Arbeitsfläche laufen parallel zueinander angeordnete über Kettenräder i geführte endlose Ketten 2. An jedem --zweiten oder dritten Kettenglied d. ist an jeder Kette eine Spamivo,-richtung zum Festhalten der Scheite 3 in Form eines tsreifers gelenkig angebracht, von denen einer in Fig. i schematisch gezeichnet und mit 6 bezeichnet ist. Bei der Aufwärtsbewegung werden die Scheite von den Kreissägeblättern 7 in Stücke geschnitten, wobei die Kreissägeblätter so gegeneinander versetzt sind, daß jedes Scheit gleichzeitig nur von einem Sägeblatt geschnitten wird.D s along the Arbeitsi - bewe logs, e surface 3 of the sawing machine diagonally upwards. Along this work surface, endless chains 2, arranged parallel to one another, run over chain wheels i. On every second or third chain link d. a Spamivo, direction for holding the logs 3 in the form of a tsreifers is attached to each chain in an articulated manner, one of which is shown schematically in FIG. During the upward movement, the logs are cut into pieces by the circular saw blades 7, the circular saw blades being offset from one another in such a way that each log is only cut by one saw blade at the same time.

Jede Spannvorrichtung besteht nach den Fig. 2 und 3 aus einem mit Aufrauhungen oder Spitzen versehenen Greifer ä, der um den Kettenbolzen c) drehbar ist und an das Scheit bzw. an die Stücke des Scheites durch eine Feder io angedrückt wird. Diese Feder ist in ihrem mittleren Teil um ein auf den Kettenbolzen geschobenes Distanzrohr i i gewickelt. Um das benachbarte Distanzrohr i i ist das eine Ende einer Spreize 12 gebogen, während (las andere Ende durch eine Windung der Feder gesteckt und unter das Distanzrohr ii geschoben ist, wodurch die freien Enden der Feder den Greifer gegen (las Holz drücken.Each clamping device consists of one with according to FIGS. 2 and 3 Roughened or pointed gripper ä that rotates around the chain pin c) is and pressed against the log or the pieces of the log by a spring io will. This spring is in its middle part around a pushed onto the chain pin Spacer tube i i wound. One end is around the adjacent spacer tube i i a strut 12 bent, while (read the other end through a turn of the spring inserted and pushed under the spacer tube ii, whereby the free ends of the Spring pressed the gripper against (read wood.

U'enn die Stücke eines Holzscheites nach obet gelangt sind, wird die Klemmwirkung der Spannvorrichtung beim Überlaufen der Ketten über das oberste Kettenrad durch das Einknicken der Kettenglieder und durch das Gewicht der Stücke aufgehoben, so daß diese, z. B. in ein untergestelltes '11ransportfahrzeug, fallen.When the pieces of a log have reached the top, the Clamping effect of the tensioning device when the chains run over the top sprocket lifted by the buckling of the chain links and the weight of the pieces, so that this, for. B. fall into a subordinate transport vehicle.
