Abstract

Usage: a multi-sawing installation can be used in the timber, woodworking and pulp and paper industries when sawing up logs into assortments. SUMMARY OF THE INVENTION: The installation is provided with transverse conveyors made of two sections: a low-speed, located in the zone of the sawing apparatus and a high-speed, kinematically connected with a low-speed section. 3 il.

Description

The invention relates to logging equipment and can be used in the forestry, woodworking and pulp and paper industries.

The purpose of the invention is to increase reliability.

FIG. 1 shows a multi-saw installation, top view, FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2

The multi-saw installation includes an overpass 1 with take-overs 2. an uncoupler 3, equipped with screw rollers 4, a feed roller table 5, in the middle of which a lifting end-leveling wall 6 is installed, a shedding unit 7, an auxiliary conveyor 6. a waste conveyor 9 with a bunker 10, receiving forest transporters 11 dumpers 12 Eleson accumulators 13, as well as movable along the rails 14 with the help of rollers 15 bases 16.

On each movable base 16, a moving mechanism (not shown), roll 17, sawing machine 18, two

low-speed transverse conveyors, each of which consists of a drive sprocket 19 and a driven sprocket 20, connected by a chain 21, to which stops 22 are attached, as well as two high-speed transverse conveyors, each of which consists of a leading sprocket 23 and a driven sprocket 24, connected by a chain 25, to which the lugs 26 are fastened. Moreover, the lengths of the high-speed transverse conveyors between the adjacent movable bases 16 are the same.

The drive sprockets 19 are rigidly mounted on the shaft 27 connected to the gear 18. The sprocket sprockets 20 and 24 are equipped with a tensioning device consisting of a slider, which is hingedly connected to the axis of rotation of the sprocket (which is not shown), moving along the guides by means of a screw transmission. . The drive sprockets 23 are rigidly mounted on the shaft 29, which is driven in rotation from the shaft 27 through the multiplier 30.

§ cl

Multi-saw installation works as follows.

A bundle of whips from the vehicle is unloaded on the overpass 1, where it is fed to disconnector 3 by means of pick-up devices 2, which individually sends out the whips to the roller conveyor 5. The operator selects and includes a whip cutting program. According to a predetermined program, the movable bases 16 are moved by means of rollers 15 along rails 14 to certain positions. The feed roller 5 moves the whip along the lifting butt-leveling wall 6, and the screw rollers

4The whip is dropped onto the slopes of the 17 movable bases 16 and onto the auxiliary conveyor 8 ,.

If filed on the serving roller

The 5 whip needs to be cut according to another program than the previous program was installed, and the subsequent whip needs to be cut according to the previous program, then the butt-leveling wall 6 is lowered, and the whip fed to the live rollerglass 5 is moved beyond the lifting butt-leveling wall 6. This whip is there

until his cutting program coincides with the same program of the newly submitted whip. Thereafter, the whip is returned back beyond the lifting end leveling wall 6 and sent for sawing. This is how the reduction in the number of iz-is carried out. changes in the programs for the opening of the installation for a certain time.

From the slopes 17, the whip is picked up by the stops of the low-speed conveyors and due to the movement of the chains 21 through the sprockets 19 and 20, as well as due to the operation of the auxiliary conveyor 7, it is moved through the distributor 7 and the saw units 18, which cut the whip into assortments. The sawdust waste falls on the waste conveyor 9, which transports them to the bunker 10, where they are transported by any means of transport. Cut logs from a low-speed conveyor fall to a high-speed conveyor, where they are picked up by stops 26 and due to the movement of chains 25 through sprockets 23 and 24 are moved to receiving forest transporters 11. Synchronizing the rotation of sprockets 19 rigidly attached to the shaft 27 rotating from the drive 28 and sprockets 23, rigidly attached to the shaft 29, rotating from the shaft 27 through the multiplier 30, the coordinated movement of the stops 22 and 26 is achieved, and the speed of movement of the chain 25 is necessary. As a result, this ansportera assortment of high-speed conveyor belt moves along /. Further, the assortments fall from the high-speed conveyor to receiving forest transporters T1, which move them to the dumpers 12. These dumpers 12 transfer the accumulators to the forest accumulators 13.

The use of a low-speed section of the cross conveyor allows an increase in the reliability of the installation, since the sawing process occurs at a reduced speed.
