The device for feeding logs to a woodworking machine contains a V-shaped log tray in the form of conveyors 2 mounted on frame 1 with cylindrical rollers. Conveyors are parallel to each other and the direction of flow, at an angle to the horizontal plane of the roller tables. The rollers located against each other form a section. The lower part of the tray (axial line) coincides with the axis of the log feed. The rollers of the live rolls are made of non-driven, freely rotating. Between the roller tables in the lower part of the tray on frame 1 there is a feed conveyor 3, the upper branch of which is located in guide 4 and the lower branch in guide 5. The guides are fixed on frame 1. Guides 4 and 5 are made of a channel, and in the middle channel guide 4 is attached by, for example, welding strip iron for rolling the chain rollers, for example, of the type RLP of conveyor 3. Guide 4 is located on frame 1 coaxially with the axis of the log. To the outer cheeks of the chain of the conveyor 3 is attached, for example, by welding at a right angle to the longitudinal axis of the chain, the stop 6, made in the form of a rectangular plate. The plate is welded to the narrow side,

equal to the width of the chain. The conveyor 3 is driven by a gear motor 7, a drive 8 and a driven 9 sprocket mounted on frame 1. The conveyor 3 is tensioned by moving the sprocket

9 along the feed direction, for example with screw pairs.

On frame 1, at least two pairs of drive wheels 10 are installed. The co- and scaffoldings are installed symmetrically with respect to the longitudinal axis of the tray and have axes parallel to the axis of the tray. The axes of the wheels are located relative to the axis of the tray at a distance equal to half the diameter of the supplied logs. The wheels 10 are rigidly mounted on the frame, have the same height as the plane passing through the upper forming rollers of the conveyors (the outer right wheel is with the right, and the left with the left rollers of the conveyors 2). In the wheels 10 along their periphery in parallel with the generators, for example, radial slots 11 are made by milling. Perpendicular slots m 1 1 in the middle of the wheel width, milling seats are selected for axles 12 on which pointed disks 13 are mounted. Axes 12 with discs 13 are fixed in the wheel

10 by means of welding, for example, in such a way that the disk 13 is in the | slot 11 and protrudes 5-10 mm above the outer cylindrical surface of the wheel 10. The penetration of the disks 13 into wood does not cause a decrease in the output of sawn timber, since this is the so-called Pythagorean zone the log (square with a side of 0.707 diameter), and the rest of the peripheral portion of the log is used for chips. In this case, due to the different strength of the wood for cutting along and across the fibers, the log is rotated around the longitudinal axis.

The disks 13 are made with pointed external generators and are installed with

the possibility of free rotation on the axles 12. The wheels 10 are driven by a reversing gearmotor 14 mounted on frame 1 and a belt drive 15. The driven pulley can be integral with the wheel 10.

The log 16 is located in the V-shaped tray on the frame of the conveyors 2. Along the turn of 1 the log is carried out on the non-longitudinal axis of the tray the required value is set for its simultaneous processing machine T7.

The device works as follows.

movement in the longitudinal direction. After the end of the log turn, the wheel drive 10 is turned off. When turning the log, the displacement of the working branch of the conveyor 3 relative to the axis of the log feed does not occur due to the presence of guides 4 and 5, as well as the possibility of tensioning the chains

Includes - 25 made its processing. Stop 6, for example, the operator of the motor-reducer conveyor 3 after the filing of the log 16 torus 7, and through the leading I and the driven 9 sprockets, the conveyor 3 is set in motion. The stop 6 comes into contact with the log 16 and informs him of the movement 30 in the longitudinal direction. The rollers of the roller conveyor 3 are made freely rotating around the longitudinal axis. Under the force of gravity of the log 16, the disks 13 of the wheels 10 are cut into the 35 woodworking machine. This is wood. Since the discs 13 are mounted through the use of axles 12 on the slots 11 with the wheels being oriented with the softness set in free rotation in their discs, which have possibilities parallel to the direction, the cavity can rotate freely. in the planes of the log, neither the rollers of the roller 40 tons, parallel to the feed axis of the conveyor 3, nor the discs 13 prevent the movement of the log 16 in the feed direction. In addition to the TOIO, the discs 13 are prevented. The device for feeding the logs in the rotation of the log 16 around the woodworking machine includes a 45 frame, in which a V-shaped log tray is installed, consisting
