SU239112A1 - DEVICE FOR SORTING and rafts of logs - Google Patents

Description

BACKGROUND OF THE INVENTION The invention relates to a device for sorting and rafting logs used in timber raids.

Devices are known that include a floating base on which a receiving conveyor with grippers, a chain dividing conveyor, log ejector, facing devices, accumulators and raft cameras are installed.

These devices require the use of manual labor, do not provide high-quality sorting of wood.

The aim of the invention is to improve the performance of the device.

This is achieved by the fact that the end faces are made with a fixed frame, on which the guides are installed with a driving mechanism moving along them, transmitting force to the end shields through a rotating working shaft on which the moving couplings are mounted. Tight-fitting chamber is made with a movable rod, to which the beam crimping cables are attached.

FIG. 1 shows schematically the described device; in fig. 2 - receiving and sorting section, side view; in fig. 3 - receiving and sorting section, top view; on fit. 4 - railing section, side view; in fig. 5 - the same, top view; in fig. 6 is an end viewer, side view; FIG. 7 is the same, top view.

The device for sorting and raft-bracing includes interconnected receiving, sorting and rafting sections mounted on floating bases. The receiving section A contains a receiving conveyor 1 with grippers 2, a lifting cylinder 3, a chain dividing conveyor 4, a cylinder-divider 5, a storage device made in the form of a movable gripper 5 with a drive 7 and

fixed capture 8. Under accumulate. A longitudinal conveyor 9 was installed. In order to develop substandard wood (short fragments of logs, wood chips, bark, knots), wicks were installed that cover the space between the chains of conveyor 1 and conveyor 4. The edge of shield 10 is above the conveyor 9.

Sorting section B contains a transverse conveyor 11 with grippers 12, a ejector 13 with a drive cylinder 14 and a storage device made as a movable gripper / 5 with a drive 16 and a fixed gripper 17. A longitudinal conveyor 18 is installed under the hopper 18. To determine the quality of the log ends, a mirror 19 is installed .

The railing section B includes a conveyor spreader 20 (see Fig. 4) with an abutment (not shown) which is rotated relative to the pivot bearing 21 under the action of a dimensional-dimensional 24 n grid with a movable rod 25 to which the crimping cables 26. are attached. inclined guide 27 from the actuator 28.

Section B is also provided with an end cutter 29 with a fixed size 30 and guides 31, but the drive mechanism 32 moves m. The drive mechanism through a rotating working shaft 33, representing BINT with left and right threads, and then through the couplings 34 and the rods 35 transmit the force to the end shields 36. The rafting chamber is equipped with an exhaust gate 37, driven by the driving cylinder 38 and the winch 39, which serves to pull the pucca of the logs. To tie the bundle of logs on section 13, coils 40 are installed with the bridging core. Each section has a cabin / dl operator.

The device is assembled from the above described sections in a specific order, depending on the width of the river on which the ravings of the logs take place and on their range. Before receiving conveyors, booms 42 are installed (see Fig. 1) to form corridors, and behind the last sorting section, ramps 43 and booms 44 are installed to form wallets.

The device works as follows.

Logs from Zania enter the “Oridor formed by Bon 42”. Workers unfold the logs into the transverse shest. The shear logs float to the harness. I and the transporter, using the grippers 2, catch it. The conveyor / logs are delivered in a continuous flow to the conveyor 4, which, using cylinder dividers 5, separates the logs one from another with an interval equal to the distance between each two adjacent grippers 12 of the non-cross conveyor //.

The logs are separated from each other as follows.

A continuous stream of logs approaches the lowered rods of the cylinder-dividers 5. Conveyor 4, moving, cannot move the logs, since there are no grippers on its chain. Kopda operator raises the shafts of the cylinder 5 ,. The logs are moved together with the conveyor chain 4. As soon as one log passes through the cylinder-divider rod, the operator stops the movement of the logs by lowering the cylinder rod. When the log begins to roll down the diverter 13 (or dumped into the hopper), the operator skips the next log, etc.

The conveyor chain / is moving at a slower speed than the conveyor chain 4. because the conveyor / logs are moving in a continuous stream, and the conveyor 4 converges at intervals.

Waste from the storehouse together with logs (nni, logs, chocks, etc.). For separation of waste, shields 0 are installed, which cover the space between the chains of the transnorter / and conveyor 4 (shown by dotted lines).

Along with the logs, transportable / unconditioned wood enters, which moves with them to the edge of the shield 10,} collecting them into the purse for further processing.

To raise conveyor 1 above the water, cylinder 3 is installed.

Logs, skatashees with the dumper 13 on the sorting section, move on the transtierta 11, in each capture 12 one by one. The operator from. Kabin 41 chooses logs

the desired mix. When the log approaches the end of the conveyor //, a resetter is activated, which with the help of a cylinder 14 rises and the log falls into the storage chamber. After the log enters the packer chamber, lower the spreader, therefore, the unnecessary log rolls down the inclined dumper to the next sorting section. Thus, logs during the movement of the sorting sections are completely

sorted. The exported logs are delivered to the last sorting section, after which, along the slopes 43, they fall into the purse formed by booms 44.

After the accumulator chamber is filled, the movable grippers 15 are opened by means of the actuator 16 and the logs fall onto the conveyor 18, which at this moment is not moving. As soon as the cameras of the accumulator are released, the mobile grippers 15 close them

with the help of the drive 16. The volume of the accumulator chamber is formed by moving 15; and fixed 17 capture MI.

The raft of logs in a bundle is carried out as follows.

The operator of the rafting section includes conveyors 18 and yes of sorting sections and conveyor-dumper 20. As soon as the ends of the log are received until the last stop, he and conveyor 18 stop. Hierator,

including cylinder 22, the conveyor 20 tilts, and the logs fall into the raft chamber. After this conveyor becomes on the same place, the operator switches on the conveyor line 18. Pa conveyor 20 enters

another pile of logs, which is also discharged into the raft chamber.

When the required number of logs is fanned into the raft chamber, the operator turns on the actuator 28, which transmits the force

Crimp cables 26 are attached to rod 25 moving along inclined rails 27. Crimp cables 26 are attached to rod 25, with which the logs are compressed into a bundle. After the beam has been bound by means of: with: cylinder 38, the opening gate is opened. Winch 39 with the help of a cable pulls the bundle out of the raft chamber.

The ends of the logs in the raft chamber are leveled before compression into a bundle, for which purpose the stower is pre-installed along the length of the log on the dimensional grid and bolted to it. Two sleeves 34 move along shaft 33. Since the shaft has left and right threads, the sleeves 34 approach each other during one rotation and move away from each other. The shaft 33, in turn, approaches the fixed frame 30 or moves away from it. When the couplings 34 approach, the force is transmitted through the bars 35 to the shield 36, which aligns the top of the logs in the raft chamber.
