Description

(54) GUIDE DEVICE FOR DOSSG.

I

The invention relates to woodworking machinery and can be used in circular saws for sawing wood;

A boarding device is known which contains drive-guiding nozzles of disk knives located above and below the material being cut.

It is also known to be a Boarding Device for Boards, containing drive-by disk.

However, the known guiding devices have the disadvantage that the cutting knives are a passive element and do not participate in the removal of the boards from the sawing area.

The purpose of the invention is to increase the reliability of operation of the guide device by ensuring reliable removal of boards from the cutting zone.

This is achieved by the fact that the knives are mounted on two coaxial horizontal shafts having independent suspension.

one of the adjacent surfaces of adjacent disks of each shaft is made conical.

FIG. 1 is a diagram of a guide device; FIG. 2 shows section A-A in FIG. one.

Boarding device for boards contains a saw shaft 1 with circular saws 2, equipped with upper 3 and lower 4 guides, drive circular guide knives 5, one of the adjacent surfaces of adjacent disks of each shaft being made conical, two having independent suspension coaxially horizontal shaft 6 and 7, the lowering guides of the guide blades 8, the drive chain 9, transmitting the torque to the guide blades 5 from the upper 10 and lower 11 feed rollers and the sawn timber 12.

The guiding device operates as follows.

Claims (2)

Circular saws 2, located on the saw shaft 1 and having guides 3 38 and 4, saw the bar 12 into boards. The boards, coming out of the saws, fall into the guiding disk knives 5, mounted on two, having independent suspension coaxial horizontal shafts b and 7 movable in a vertical plane and driven in rotational motion by the chain 9. Since one of the side surfaces of the adjacent knives is then the boards are wedged with knives regardless of the change in the thickness of the board within acceptable limits and are removed from the area of the cutting assembly. The disk guide blades are driven from the falling rollers 10 and 11 by means of a chain transmission 9. The lowering guide of the guide blades 8 serves for lifting and lowering them depending on the log of the saw. The guide for the boards ensures reliable removal of the extreme boards of the set from the cutting edge and prevents the boards from being ejected by the rear (repacking) saw teeth. At the same time, it secures the technological reliability of the machine for sawing the boards and eliminates the marriage of the outermost boards in thickness. DETAILED DESCRIPTION OF THE INVENTION Board guide for boards containing drive circular knives, characterized in that the knives are mounted on two independently mounted coaxial horizontal shafts, one of the adjacent surfaces of the adjacent disks of each shaft being made conical.
