(54) DEVICE FOR DISSEMINATION OF THE BOTTOMED TO THE CONVEYOR OF THE SHORT-QUALITY LESOMATERIAL

one

The invention relates to the forestry, industry, and construction of devices for the disassembly of short-sized timber that has been piled onto t {).

A device is known for disassembling short-sized timber piled onto a conveyor, comprising an auxiliary conveyor with cross-beams, trays from a guide, crosses and a timber piler 1.

The disadvantage of this device lies in the impossibility of single-piece separation of timber and oriented dumping of the packer.

The purpose of the invention is to provide for piece-wise separation of timber and oriented dumping of them into the packer.

For this, the device is equipped with clamping spring-loaded rollers mounted above the auxiliary conveyor, and the guide is installed between the trays and is made in the form of an angled beam with shelves inclined to the trays, while the trays are mounted with the possibility of their rotation, and the traverse is made with saddles opposite the trays .

FIG. 1 schematically shows the device described in perspective; in fig. 2 - the same, side view; in fig. 3 is the same, view A of FIG. 2; in fig. 4 is an electrical circuit of the device.

The described device contains a conveyor 1, at the end of which an auxiliary conveyor 2 is installed with cross-beams 3 made with saddles “a. Above the cross-arms 3 at the end of the conveyor 2 4 rollers 5 are placed on the swing arms.

The levers 4, by means of the springs 6, are pressed against the limiting bar 7, which is set at such a height that the gap between the traverses of the conveyor 2 and the rollers 5 is smaller than the diameter of the thinnest timber.

15

Downstream of the conveyor 2 is a separator 8, made in the form of a corner beam with shelves 9 and 10 inclined to the trays 11 and 12. Trays II and 12 are locked with spring-loaded dogs 13 and 14 connected with electromagnets 15 and 16.

Claims (1)

The electromagnets 15 and 16 are turned on by limit switches 17 and 18, controllable flags 19. - Crosses 20 and 21 are installed under trays 11 and 12, each of which is made with interfering plates 22 forming the trays. Crosses reassembled on bearings. The crosses are made with ratchet wheels 23 and 24 interacting with pod-, spring-loaded dogs 25 and 26 connected to electromagnets 27 and 28. Electromagnets 27 and 28 are turned on, and switches 29 and 30 are installed in the trays of crosses 20 and 21 strips 31 and 32. The device works as follows. With an unorganized arrangement of short-sized timber on conveyor 1, they can be moved two or even three together (with small diameters) with full or incomplete overlap of lengths. When transferring the assortments from conveyor 1 to conveyor 2, prerequisites are created for separating them into two parallel flows due to the fact that the traverse 3 of the conveyor 2 has saddles "a. Upon further movements of the timber, the rollers 5 roll over them. The rollers 5 press the timber to the conveyor 2 by the force of the springs 6 and thereby support the assortments in a horizontal position, eliminating excessive filling of their front ends into the trays Pi 12, which are located slightly below the support plane of the traverse 3 of the conveyor. Due to the fact that all rollers 5 are mounted on separate independent levers, simultaneous horizontal positioning of the front ends of thick and thin wood materials is ensured. When the rollers come off the timber, the latter are dumped into the trays 11 and 12. A separator 8, mounted in the plane of the longitudinal axis of the conveyor 2, ensures that thick timber gets into both trays. If two thin timber are located on one of the sides of the transport 2, they fall into one tray, which is permissible, since it is desirable to transfer thin timber to the piler, two or three together. When fully dumping the timber into the trays of And and 12, they act on the flags 19, as a result of which the contacts of the switches 18 and 17 are closed, the electromagnets 16 and 15 turn on, which are disengaged from the wheels 23 and 24, the pawls 25 and 26. Under the action, The tilt plates and the materials of the trays 11 and 12 are rotated on the axles, and the materials are dumped into the trays of the crosses 20 and 21. The trays are returned to their original position using their counterweights and springs (not shown). The time during which the timber is dumped from the tray and the latter is returned to its original position is less than the time spent feeding into the tray of the next timber due to the fact that rollers 5 support the sort §1 t with a significant cantilever overhang of its front end, trays 11 and 12 are locked dogs 13 and 14 by the time the next timber is dumped in them. In the trays of crosses 20 and 2, the timber presses the rear ends on the spring-loaded strips 31 and 32 connected to the limit switches 30 and 29, which turn on the electromagnet 28 and 27. The crosses are rotated at a 90 ° angle under the weight of the assortments and dumped on the palletizer. Following this, the crosses are fixed by spring-loaded dogs 25 and 26. Claims of the invention A device for disassembling a short-sized timber piled onto a conveyor, containing an auxiliary conveyor with cross-arms, trays with a guide, Timber pallets and palletizers, characterized in that, in order to provide for a case-by-case separation of the wood products and their oriented dumping into the palletizer, it is provided with spring loaded pressure rollers mounted above the auxiliary conveyor belt to the trays, with the trays mounted with the ability and) rotation, and the traverse is made with saddles located opposite the trays.
