Description

one

The invention relates to the sawmill industry.

A band sawing machine for longitudinal sawing of logs is known, including a bed, a support with a vertical displaceable platform, on which is mounted a manipulator pivoting about a horizontal axis, a saw belt pulleys with a centering device and a transverse conveyor.

The purpose of the invention is to increase the reliability of the machine.

For this, the manipulator is made in the form of two telescopic consoles, one on which is extendable, and the other is fixed on a platform moved in a vertical direction.

FIG. 1 shows the proposed band-saw machine, side view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 - machine, top view.

The machine includes a frame 1, a support 2, a platform 3 movable in a vertical plane, on which is mounted a manipulator 4, containing two telescopic L-shaped arms 5 and 6, of which the latter is fixed in bearings 7 on platform 3, and the other is moved by means of a hydraulic cylinder 8, mechanisms 9 for turning the log, hydraulic cylinder 10 for turning the manipulator relative2

the horizontal axis, the L-shaped levers 11 with the hydraulic cylinder 12, the horizontal guides 13 of the bearings 7, along which the torus moves in the lateral direction receiving plugs 18. The device works as follows.

The log is fed by the feeder 16 to the receiving forks 18, with which it is raised and centered. The diameter of the ends of the log is determined by a measuring device and the nrogram is cut accordingly.

The manipulator 4 from the initial position is rotated by 90 °, the L-shaped console 5 is extended to the maximum possible position. Then the hrn helper 8, the console 5, swings to the bracket 6, and the log is clamped

at the end of the hydraulic cylinder 10; the arm with the log is turned in the direction of the sawing organ, while at the same time not moving transversely to produce the first nronnl. The perforation was pierced by vertical thrusting from the bottom up to the side of the torus 4 with the log. At the end of the kerf, the manipulator automatically lowers, the log rotates 90 ° around the nrodol axis, moves in the transverse direction and

re-sawn. Slab, podgor3

The board and the timber are cleaned by the cross conveyor 17.

Subject invention

Band-sawing machine for longitudinal sawing of logs, including a bed, a support with a platform moved in a vertical direction, on which a rotatable relative to the horizontal

axes a manipulator, screws with a band, a logger with a centering device, and a cross conveyor, characterized in that, in order to increase the reliability of the machine, the manipulator is made in the form of two telescopic consoles, one of which is second pull-out and the other mounted on a vertically movable platform.
