Description

DEVICE FOR SORTING FOREST MATERIALS

one

The invention can be used in the timber and woodworking industry for sorting timber and sawn timber, such as sleepers.

A device for sorting timber products is known, which includes a working body (rod) of reciprocating movement with laying, pushers pivoting in the longitudinal vertical plane mounted on the frame along the pockets, and a double rail for cargo with curtains rotating in the transverse vertical plane.

However, the known device has a large metal content and a large weight of the working body (rod). In this connection, the structural elements are subjected to large inertial loads, which relieves the drive of the device and increases the energy consumption of the sort.

The purpose of the invention is to reduce the weight of the working body and reduce energy consumption.

This is achieved by the fact that the working body is made in the form of a closed traction body, for example a cable located in a horizontal plane, both branches of which, mounted parallel to the tray, are working. In addition, to keep the pushers in a vertical or inclined position, they are connected to the working body by means of racks whose shanks are located in

longitudinal grooves of the frame with the ability to move along the latter.

FIG. 1 shows the proposed device, a cross-section; in fig. 2 - the same, top view.

The device contains a working body 1 located along the storage pockets, made in the form of a closed traction body,

for example a cable, both branches of which are driven back and forth by means of a drive pulley 2 located in a horizontal plane. Tensioning pin 3 has the ability to mix in

the direction of the longitudinal axis of the sorting device to provide a working tension to the rod. On both branches of the traction organ, they are fastened at certain intervals between the legs 4 and the shanks;

which are hinged mounted tiltable in one direction pushers 5, returned to the working (vertical) position under the action of a spring or counterweight (not shown in the figures) and held in such

the position of the mechanical limiter (not shown in the figures). When the tool is idling, the pusher, when it encounters the timber in the groove of the tray, is transferred by it into horizontal or

inclined position and in that position

passes under it to the starting position for work.

The clamping device 6 racks allows them to be moved along the cable end (cable) in order to regulate the accuracy of the cargo discharge and adjustment to different lengths of the sortable loads 7. The shanks of the racks move in the guide grooves 8 parallel to the tray. The double groove tray consists of two inclined roller conveyors 9, along which the weights move, and curtains 10 rotating in the transverse vertical plane with counterweights 11 forming the outer limiting sides of the grooves of the tray. In the working (raised) position, the flaps are held by a latch (not shown in the figures), which is unlocked by a control device from the operator console. The blinds are folded under the action of their own weight of the product being sorted, and returned to their original position by means of a counterweight 11 or a spring.

The device works as follows.

From a mechanical, pneumatic or hydraulic system, a working member is provided, both branches of which begin to perform reciprocating motion with an amplitude of oscillation that is somewhat longer than the material being transported, which is necessary to return the plungers to their original operating position. At the same time, when one branch makes a working stroke and moves all timber located in the zone of action of its pushers, the second branch idle, returning the pushers to their original position for work. This alternation of working and idle strokes ensures a uniform loading of the drive and a high utilization rate. The wood products then move along both troughs of the tray in the same direction. When the location of the stops of one branch is different

It is possible to transport two troughs in opposite directions, but at the same time there will be no uniform loading of the drive of the device.

When rearranging the stops on the reverse flow, for example, on half of each branch of the working device, the loads can be moved along each chute of the tray towards each other and dropped in the middle of the sorting

devices. In this design, one device can serve, for example, four saw machines.

At the time of stopping the working body, the control device (not shown in the figures) opens the latch of the slider where the dumping of the timber must occur. Reset occurs under the action of its own weight of the sorted cargo.
