Device for turning tree trunks on a log carriage

The invention "relates to a device for Turning logs on a log carriage of a vertical log band saw.

It is known to mount driven chain arms on the log carriage of a log band saw on the loading surface of the log carriage, which are arranged approximately horizontally and are used to be able to rotate the trunk. · With such a chain arms can be a tree trunk just ι in one direction turn, so forward, because if

the workpiece in the opposite direction, i.e. after

If you want to turn backwards, i.e. against the clamping block, the workpiece will jam on the clamping block. In addition but also that the workpiece is supported by additional arms, so-called flipper, must be secured in order to prevent the workpiece from being removed from the block carriage during this rotation falls down. If such a workpiece is rotated too much with the help of the chain arms, there is no reversing more possible and the whole process must be repeated.

that there is a risk of falling from the block wagon stands.

The solution to this problem has now been found in the fact that, in addition to driven chain arms, on a block carriage, which are arranged approximately horizontally, preferably rising slightly towards the saw, and more vertically standing chain arms are provided, which can be moved horizontally.

An example of a device according to the invention is sketched in the attached drawing.

A block carriage 1 has driven chain arms 2

equipped in its support surface, which are inclined slightly upwards towards the saw. There are also Vertical chain arms 3 installed, which can be moved horizontally. The chain arms 2 and the chain arms 3 run at the same speed and can both forwards and backwards to run. Because the vertical chain arms 3 are horizontally displaceable, can they cover the protruding clamping claws 4 ·. Therefore, they are used when loading the log truck with the tree trunks additionally as protection for the clamping brackets.

In Figure 1 it is shown that a tree trunk 5 ·! is up like from can be seen in the directions of the arrows, can be rotated both forwards and backwards.

comes to rest on the lower chain arm 2 (see sketch Figure 2 with tree trunk 5.2 ') »so that then further cuts can be made perpendicular to the surface that was cut first.

When a few cuts have been made in mutually perpendicular directions (Figure 3) _T one can turn such a partially trimmed tree trunk 5x3 again in the direction of the arrow so that (see position 5-3 ') the tree trunk is then already parallel to the one trimmed side can be provided with further cuts. But you can also twist a tree trunk 5-4- (Figure 4) that has already been pruned on two parallel surfaces, so that it is with one

these cut surfaces rests on the chain arms 3 and then perpendicular to the two "previously trimmed areas" further saw cuts can be made (see position 5.4- ').

It is thus shown that with the device according to the invention, which makes it possible to move the trunks in both directions to rotate compared to the known devices on a log carriage of a log band saw significant advantages are.
