Description

Pusher input conveyor pusher: saw.

Technical field

The present invention relates to a pushing device for inlet conveyors of a rip saw.

BACKGROUND OF THE INVENTION

Pushbars attached to driven roller chains are used in the inlet conveyors of the rip-off saws for sawing logs. The compression arms are supported in the central part on the ends of the saw cut-outs and pass simultaneously with the saw cut-outs during cutting through the area of the saw blades and push the central lumber beyond the rip saw. Chains with pressure arms attached pass through the rip saws and circulate around.

This arrangement requires split saw spindles, the design of which is very complex * Another disadvantage is that due to the dimension of the compression arms and roller chains the minimum thickness of the central sawn timber is approx. 60 mm * This uncut center must be further processed on another machine *

SUMMARY OF THE INVENTION

These drawbacks are eliminated by the pushing device of the inlet conveyors of the rip saw according to the invention, which is characterized in that the pushing thumb connected to the drive and attached in the guide of the inlet conveyor is provided with a wood in the front part.

It is easy to manufacture a pushed thumb with a timber · Changing the timber when changing the timber assortment is easy »The use of the timber makes it possible to make any number of boards from a saw cut without limiting their thickness, even from the widest central part. ·

BRIEF DESCRIPTION OF THE DRAWINGS

An example of an embodiment of the invention

In the horizontal guide 4 of the inlet conveyor, the pressure thumb 4 is provided with rolling timber 3 in the front part by means of rolling rollers 7. The pressure thumb 4 is attached to a roller chain 6.

The saw cut 4 is pushed into the cut by the pushing thumb 4 with the timber 3 until it is completely cut. At the same time the front part of the timber 3 is cut. After the saw cut 2 is cut, the pushing thumb 4 with the timber 3 returns to its original position. cut, then pushes the other ends of the sawmill 2 to be swept into the cut ·

Wood 3, may be of wood or other easily cut material ·

Instead of the roller chain 6, another method of driving the thrust thumb 4 can be used, e.g.
