(54) DEVICE FOR FORMING ROUND FOREST MATERIALS

The invention relates to equipment for processing cargoes in the timber industry, and in particular to devices for forming packages of round timber.

A device for forming packages of round timber is known, comprising a movable store including a base and racks, a feeding mechanism and a guide mechanism mounted at an angle thereto.

one.

The disadvantages of the known device are the low quality of package formation due to the high height of the load falling into the accumulator. In the initial formation period and the lack of reliability of the device due to the absence of restrictive elements of the accumulator.

The goal of the invention is to increase the reliability of work and the quality of package formation.

The goal is achieved by the fact that the device is equipped with limiting levers fixed above the accumulator in the vertical plane, the ends of which are unfolded at the upper edges of the accumulator walls, the feeder mechanism is a conveyor, and the forward mechanism contains an envelope of an endless flexible body on which rigidly fixed at an angle to its surface, an emphasis with a roller mounted with the possibility of interaction with the walls of the accumulator, and a counterweight connected by means of a trough block system. with

10 top sprocket, which is mounted on the driven conveyor shaft.

FIG. 1 shows the proposed device, top view; on Fig. 2. same, side view on fig. 3 - section

15 A-A in FIG.

The device comprises a bunker 1 for loading timber with a timber transporter 2, a live roll 3 with a drive 4 for dispersing, leveling and

20 overclocking assortments. The speed of rotation of each subsequent roller increases due to the appropriate selection of drive sprockets on each roller.

The device also contains a feeding mechanism, which is a conveyor 5, single sprockets of which are freely mounted on the shaft 7, on both sides of the conveyor

30, vertical sides 8 and 9 are provided to align the ends of the transverse aunt of the timber. Board 9 has a separate thrust unit 10 movably mounted on the shock absorbers to receive and soften the impacts of the ends of the assortments delivered by the roller table 3. The distance between the boards can be varied depending on the length of the packaged grades. The device has a guide mechanism, made in the form of an infinite flexible body 11, enveloping the sprockets 12 and 13, the lower sprockets 12 freely rotate on the cantilever axles, and the sprockets 13 are rigidly fixed on the shaft 7. On the flexible organ The cantilever planes 14, supports 15 are fixed, on the edge of which the rollers 16 are CONSOLINATELY mounted. On the shaft 7 there is a rigidly fixed drum 17 with a cable 18 for attaching the counterweight 19. On the track 20 there are movable stores 21 with front 22 and rear racks. The stops 15 of the G6 rollers at the initial moment of package formation interact with the inner surface of the front pillars 22 of the accumulator 21. For the unimpeded passage of the accumulator from the package formation area, the distance between the rear pillars is smaller than between the front ones by an amount sufficient to eliminate the possibility of interaction between the rear pillars with rollers 16. The device is also equipped with vertically rotatable limiting levers 24 with rollers 25, which are concosable at the end, a gesture fixed on a horizontal turn SG shaft 26 mounted nadnakopitel mi. The levers 24 at the beginning of the formation of the package kami 25 interact with the upper edges of the racks of the drive. The device works as follows. Logs from the hopper 1 by the conveyor 2 are fed by an unoriented stream to the live rolls 3, on which they spread, level and toward the end of the roll table, speeding up to the required speed, they move by inertia until they meet the ends of the hard part 9 of the board and fall onto the conveyor 5. Disperse The ends of the logs are limited by sides 8 and 9, which are installed with a slight tapering towards the end of the conveyor, thanks to which the run-up of the ends of the logs in the brush is reduced to the minimum value. The first assortments, reaching the end of the conveyor 5, fall onto the stops 1 of the guide mechanism, which in the initial position under the action of the counterweight 19 occupy the extreme upper position and their rollers 1b touch the inner surface of the front posts 22 of the storage ring. In the same position, the accumulator with its front pillars interacts with the limiting pivot levers 24, guiding the assortments into the accumulator and preventing the handling of the assortments behind the front pillars. As the timber arrives at the stops 15, the operator periodically briefly switches on the drive for moving the drives, advancing the drive located in the packing area. In this case, the stops 15, under the influence of the weight of the assortments laid on them, overcoming the resistance of the counterweight 19, gently lower down, following the drive posts by an amount determined by the amount of movement of the drive front posts, under the influence of the drive posts are turned by an amount corresponding to front racks drive. Thus, the amount of lowering of the lugs 15 with the assortments laid on them is determined by the amount of movement of the accumulator, i.e. its front pillars, with the inner surface of which interact the rollers 16 of these stops. Due to this, at the initial moment of forming the package, assortment of assortments is ensured. When moving the accumulator forward, the stops 15 descend to the lowest position and come out of contact with the front posts of the accumulator, gradually lowering the assortments onto its base. In the future, the formation of a package of timber goes without destiny yno-i ditch 15, which are squeezed out of timber and are in the lowest position. The formation of the package is carried out at a minimum height of timber dumping, which ensures the quality of laying. In the process of moving the accumulator, the limiting levers 24 come out of contact with the front arms and slide along the surface of the timber package. When the accumulator leaves the package formation zone, the stops 15 of the guide mechanism are returned to their initial upper position by the action of the counterweight 19, the limiting lever 24 is rotated about the axis and resting on the front posts of the next accumulator. The use of the proposed device provides quality.

forming a package of round timber when packing goods into a hopper, which allows to improve the conditions of transport and loading and unloading operations with timber cargo packages.
