Description

one

The invention relates to devices for stacking sorted boards into dense transport packages of predetermined dimensions and can be used in devices for sorting boards according to lengths.

Devices for laying timber into dense transport packages are known, including a loading mechanism, a frame with vertical front and rear pillars, a vertical frame for swinging a set of boards and a storage pocket.

However, using known devices, it is possible to skew the thin ribs and a set of them on a swinging frame, as well as a significant run-up of the ends of the boards in the package being formed.

The purpose of the invention is to ensure the quality formation of boards in dense packages.

This goal is achieved by the fact that the front end of the frame is equipped with sliders, movably mounted in the vertical grooves of the front pillars, and the rear pillars are connected to the frame by means of pivotally fixed intermediate arms on it. The frame is equipped with a closed traction body with transverse traverses interacting with the cams attached to the front pillars attached to the fixed-side locking paws of the horizontal frame.

In addition, the pocket-nipple should be provided with spring-loaded flaps for lateral sealing of the board pack.

FIG. 1 shows the proposed stacker, general view; in fig. 2 - then, top view; in fig. 3 is a diagram of a stacker with a pocket; on fng. 4 shows a section A-A in FIG. 3; in fig. 5 shows the node I in FIG. one; in fig. 6 — node AND in FIG. 3

The stacker comprises a frame 1 rocking in a vertical plane to form a row of planks, on both sides of which are sprocket-roller chains 2 connected by two cross-beams 3. In the initial position one cross-bar is on the working branch in the extremely rear part of frame 1, and the other cross-bar is on the idle branch of the extreme front of the frame. Chains with traverses are driven by an individual gearmotor 4 through a chain drive 5. The swinging frame 1 is hinged on two rigidly connected intermediate arms 6, the lower ends of which rest on the rear CToiiKy with the bearing 7.

And the rear end of the frame 1, on a special suspension fixed motor-gear 4, under the action of the weight of which the frame 1 automatically takes a horizontal position. The front end of the frame is equipped with two sliders 8, located in the vertical grooves 9 of the front struts 10.

On the uprights near the vertical grooves, two automatically acting pivoting paws 11 are fastened, and with the help of which the swinging frame 1 can be fixed in a horizontal position.

On the hubs of the driven sprockets 12 mounted on the front end of the frame, the cams 13 are fixed, intended for turning the dogs 11 and unlocking the frame 1.

On frame 1 there are two roller tires 14, which facilitate the formation of a number of boards.

To feed the boards from the sorting device to the stacker, use inclined roller tires 15 and a tappet 16 of the transversely mounted conveyor.

On the main platform of the karman-drive

17Installed two spring-loaded sash

18-fold transverse compaction of a number of boards when laying it on the package 19 being formed. The flaps 18 are fastened with their vertical axes in the bearings of the supporting platform of the storage pocket 17 and the transverse beam.

20, mounted on support columns 21. The ends of the flaps 18 are connected by flexible rods 22 to a spring-loaded stem 23, which can be moved in a sleeve 24 fixed in the middle of the beam 20.

The stacker works as follows.

From the sorting device, boards of the same length are attached by chains 16 of the transversely mounted conveyor to roller tires 15 and roll them onto roller tires 14 of the tilting frame 1, where a row of a package cz of a certain predetermined number of boards corresponding to the cnr / Ina package is formed. After forming a row of boards, the motor-reducer 4 automatically turns on, which drives chain 2 with cross-pieces 3, as a result of which the driven sprockets 12 with their cam 13 rotate the pawl 11 and the frame 1 under the weight of the boards tilts up to the contact A pocket of storage accumulator 17, on which a packet 19 is formed. After further movement of the chains 2, their next yoke 3 captures the rear ends of the formed row of boards and pushes the entire row in the longitudinal direction to the supporting platform. After the end of the extension board and the traverse boards 3, it goes to the bottom

the idle branch of chain 2 and stops at the very front of frame 1, and the second traverse, the exit to the upper working branch at the opposite end of the frame: ay, presses the limit switch and turns off the gearmotor 4. At this time, the rear ends of the formed row of boards lie down to the supporting platform of the Karmap-iakopitel 17, and the frame 1 swinging off the planks under the action of the weight. the geared motor returns to its original horizontal position, where it is locked with the dogs 11.

Subsequent packet rows are formed in the same way, and their front ends when extending the next row of beds already onto previously laid rows of boards. The vertical grooves 9 in the front pillars 10 of the stacker provide for the vertical movement of the front end of the swing frame i over the entire height of the package being formed, with the result that the rear ends of the boards laid in the package are in a strictly vertical plane and the package has a regular shape.

By moving each row onto the formed package, it is transversely sealed by its spring-loaded flaps 18, whereby the formed package is made sealed and suitable for wrapping it with a metal tape.
