and open it from above. If necessary, the tray 23 in the extreme conditions of the IV levers 26 can exit from the pre-, business conveyor 2 even more.

Along the side 30 of the main receiving table 9, a distribution valve 31 is arranged, which can be rotated from the hydraulic cylinder 32 in a transverse vertical plane from position VI with an acute angle Y to the horizontal plane to position VII perpendicular to the horizontal plane.

Between the cutting unit 7 and the additional conveyor 2, an auxiliary roller 33 is installed, which improves the conditions for timber transfer from level 21 to level 22.

At the end of the additional longitudinal conveyor 2 and in front of the cutting unit 8, for the option of supplying a pack of several timber, a pivoting stop 34, pivoted from the initial position VIII to the working position IX for the preliminary alignment, is pivoted in the longitudinal vertical plane from the hydraulic cylinder. Butt of several timber products.

The receiving table 14 is installed between the tray 10 and the unit 8.

At this, it is made in the form of a drive section of a roller conveyor with rollers 35 - 39, fixed in sides 40 and 41, in which axles 42 - 45 are also placed, on which stops, for example, 46 - 49 pivoted in the longitudinal vertical plane, are fixed can be rotated from the initial position X, parallel to the horizontal plane, to the working position XI, perpendicular to this plane, under the action of hydraulic cylinders. FIG. 4 shows one drive hydraulic cylinder 50 turning, for example, the stop 48.

The receiving table 14 is provided with a drive 51 of rotation of its rollers, between which is placed a distribution valve 52 for short-sized assortments, which can be rotated in a transverse vertical plane under the action of the hydraulic cylinder 53 from position XII to position XIII and XIV for

pre-sorting of short-size assortments by separating them into out-of-line conveyors 16 and 17,

. In order to feed and precisely stop timber, including several simultaneously in automated mode, sensors 54 for additional stop positions and timber opening, such as photo sensors, which are installed in boards 40 and 41, are installed in front of the receiving table 14. 1 conventionally shown rendered beyond these boards.

External conveyor belts 16 and 17 are placed under distribution valve 52, and an additional transverse conveyor 18 is installed along the side of the tray 10 and below it, located under the main screening conveyor 12 and perpendicular to its longitudinal axis 55, and at the end of the conveyor 18 is parallel to axis 55 Additional longitudinal sorting conveyor 19 mainly for small and parts of medium thin assortments of medium lengths.

The cutting unit 8 is installed from the cutting unit 7 at a distance greater than the average length of the processed logs. For example, for the conditions of the Urals, this is 10–15 m. The main aggregate 7 and. Subsidiary 8 is located on the upper 21 and lower 22 levels of feed and spreading and operate under these conditions independently with different timber, including whips.

In addition, position 56 shows one of the possible locations for the installation of the operator control panel.

Along the main sorting transformers P and 12, on both sides of the receiving table 9, there are installed sensors of timber position, for example, photo sensors 57.

A timber cutting and sorting plant can operate in several ways.

Option 1. Coniferous business logs, including pre-sorted, of various masses from large to thin ones are processed, from which mainly sawlog is cut. Such cutting chewing sorting lines drank

Between 70% and 90% of sawn timber from the total volume of logs are used and are the target lines for supplying sawmill with sawmill.

In this case, by means of a manipulator (not shown), the whips are moved from the unloading platform in the transverse direction with partial separation of small-sized whips. Therefore, thick and medium thickness whips are mainly placed on the main feeder with a manipulator. The operator then brings the next whip to the cutting unit 7, which is used for trimming it and, if necessary, for trimming.

This is done by the aggregate 7 with the tray 23, which is retracted, for example, into the intermediate position V of the main receiving table 9 or to the extreme position of the tray 23 when the levers 26 are withdrawn to the extreme position IV for especially large, i.e. The splittings are carried out when splitting on weight with partial support at the end of cutting the butt part onto the auxiliary roller 33. Therefore, after sawing off, a large-sized or medium-thickness short haul moves through the roller 33 to the large conveyor 15 for the raw material that requires splitting, and enters the inter-operating stock of the cleaver or into the corresponding bunker.

If the trimming is done.

for example, with a whip of medium thickness, the tray 23 remains, for example, in an intermediate position V and this whip initially continues to move at level 21 of the main longitudinal conveyor 1, and then begins to outweigh smoothly, and its butt part is lowered onto the open from above when retracted to position V tray 23 is an additional longitudinal conveyor 2 to level 22, i.e. it moves from level 21 to level 22 in steps.

When the butt part of the whip approaches the end of the additional transporter 2 (for those whips that are transmitted to level 22), its apex part through roller 33 also passes to level 22, since to the level 22, whips with a length | not more than the average whip, the tray 23 is then transferred by hydraulic cylinder 28 to position I, in which it

the additional porter 2 closes on top, and the whip is moving to ypoBEie 22 of the additional conveyor 2 under tray 23.

Therefore, following the previous whip, MOVING at level 22, the subsequent whip is also moved, for example, also a large-sized or medium-sized, Jupine, but already at level 21, and with it, if necessary, trimming or collecting is also carried out from position I to position V or levers 26 to position .IV and position I of tray 23, but with valve 31 transferred to position VII.

In case of separate and independent movement of the previous and subsequent whip, the operator gives orders separately for each of them. At the same time, on the receiving table 14, for example, by the hydraulic cylinder 50, the stop 48 corresponding to the medium-length assortment is exposed from the initial position X to the working position XI, and the corresponding sensors 54 of this predetermined stop and cutting position are connected to the network 14. In addition, the corresponding sensors 57 determining the main stop and break positions are also connected to the network.

Therefore, the commands of the sensors 54 and 57 at the receiving tables 9 and 14 are carried out by independently feeding the previous and the following whip drives 3 and 4 for the given lengths of assortments.

After an exact stop, the previous and subsequent logs are opened by the cutting units 7 and 8.

At the same time, at the end of the cutting with the unit 7, the tray 23 of the main receiving table 9 with the hydraulic cylinders 25 and 28 is transferred either to position II or, for example, to position V and therefore the assortment sawn off by the main cutting unit 7 is dropped onto the main sorting conveyors 11 or 12.

In turn, at the end of the previous whip of the previous whip, the aggregate 8, which is set to the working position XI, the stop 48, is moved to the initial position X and the assortment of average length 35-39, with

In position XII, the distributor flap 52 for short-sized assortments is moved to tray 10, by which it is dumped onto the cross conveyor 18, and from there it goes to the longitudinal additional sorting conveyor 19, which, regardless of the main sorting conveyors, sorts the average lengths obtained after cutting chewing aggregate 8.

After several independent feeds for specified lengths of assortments of the previous and subsequent whips at various levels 21 and 22, the remaining when feeding the next whip to the tops — part, for example, as a part of a long multiple to two meters of the balance and tops. transferred at the allotted again, for example, to position V of the tray 23 from level 21 to level 22. At the same time, another whip can be fed, but already at level 21 when tray 23 is in position I. As before, the flat part can be dropped at positions II and VII of tray 23 and flap 31.

At the same time, it passes over the remote conveyor 15, since the apical part is not short and moves to the receiving table 14, where the stop 47 corresponding to the short dimension is set from the position X to the working position XI. At the same time, after stopping in a predetermined position of the apical part and sawing off in the position of the abutment 47, the latter rises to the X position and the short assortment of rollers 35 to 37 moves to the distribution flap 52, which is shifted to the XIV hydraulic cylinder 53. After the passage of the roller 37, this assortment falls on the external conveyor 16 for short length assortments and is transported by this conveyor to the corresponding sorting and processing units of short length assortments.

The next step is the subsequent feeding of the top part to the length of the next short assortment, and then sawing it off, moving it to the conveyor 16 and dumping the flap 52 into it. Then the top that remains from the top part, i.e. separated upper end

short-haul pillars are sawn off, and the wood longevity is separated by the main cutting unit 7 which is first on lot 10

According to its characteristics, the KOToiJbui cannot be used as a business assortment, it moves with the rollers 35 - 37 that are lifted to the X position by the rollers 35 - 37 to the distribution flap 52, which is transferred to the XIII position and therefore dumps the top onto the remote conveyor 17, which it moves directly to the chipper 13 and is ground.

The individual thin logs remaining on the unloading platform (not shown) after moving the large, dimensional and medium thickness logs are then placed on the conveyor 1 with the manipulator, and several pieces at the same time. Next, a bundle of small whips with the allotted, for example, 20 clamps, for example, also firewood 15

ke 23.

Further, the flap 31, as indicated earlier, translates from a position inclined at an angle to the horizontal plane to perpendicular position VII, and the tray 23 of the receiving table translates from position I to position II. Therefore, the firewood length falls on the additional conveyor 2 and does not fall onto the conveyor 15, with subsequent feeds at the level of 21 remaining from the part of the whip for a given length of the next assortment

thirty

at position V, tray 23 initially moves in steps from the upper level 21 to level 22, and then completely moves to the lower level 22.

In this case, the stop 34 is transferred to the 25th working position IX and it carries out the operation of pre-leveling the bale of logs with the drive 4 of the conveyor 2 turned on.

After aligning the ends of the small whips, the stop 34 is transferred from the working position IX to the initial position VIII and the pack of whips with the aligned ends moves to a predetermined length of the short assortment or the average length of the assortment set by the respective stops and sensors of the receiving table 14. Then, a pack of several fine whips simultaneously open chewed and the resulting assortments are dropped onto conveyors 16 or 17.

Option 2. Recycled medium thickness and thin logs of mixed breeds with an increased level of firewood output. In this case, the chewing-sorting plant can be designed, along with the cutting of business logs, also for obtaining, for example, raw materials for charring.

In this case, the work is carried out similarly as in the first embodiment, i.e. independently at levels 21 and 22, but with the only difference that when feeding the whips at level 21 to 55 the specified lengths of the logs, the tray 23 is in position I and if there are wood pieces of the whips from them

This range is likewise sawn off from it and is again dumped onto an additional transport unit 2, on which a pack of wood longitude of 2-3 pieces or more is formed.

This pack then moves at level 22 in the direction of the pre-axle anvil 34. At the vacant place at level 22, the next pack of longitude can then be moved or the upper parts are moved, and business pieces from this and subsequent logs are moved and opened at this time on the receiving table 9 and dumped onto the main sorting conveyors 11 and 12.

The formation of this bundle of core longness can also be carried out when the drive 4 of the additional transport is on. In this case, when successively transferring business longitude from level 21 to level 22, the role of the bundler will be performed by the emphasis 34, transferred to the working position IX.

In the considered variant, with the specialization of the cutting unit 8 on the sawing of the firewood, some units of the installation appear to be superfluous. This is tray 10, cross conveyor 18 and longitudinal transport ter 19.

In addition to the business long-haul opening, in this variant at level 2, the whole whipwinds as a whole, especially thin-grain and hardwood, can be also chewed up.

short bite grains are sawn off, and the wood longevity is separated by the main cutting unit 7, which is first placed on the lot

for example also firewood

ke 23.

Next, the flap 31, as previously indicated, from position VI inclined at an angle to the horizontal plane is transferred to its position VII perpendicular to it, and the tray 23 of the receiving table is transferred from position I to position II. Therefore, wood longhound falls on an additional conveyor 2 and does not fall on the conveyor 15, with subsequent feeds at the level of 21 remaining parts of the whip for a given length of the next assortment, before

This range is likewise sawn off from it and is again dropped on an additional conveyor 2, on which a pack of wood longitude is formed in the amount of 2-3 or more pieces.

This pack then moves at level 22 in the direction of the pre-axle anvil 34. At the vacant place at level 22, the next pack of longness can then be moved or the vertex parts are moved, and business pieces from this and subsequent logs are moved and opened at this time on the receiving table 9 and dropped to the main sorting conveyors 11 and 12.

The formation of the said pack of long wood can also be carried out when the drive 4 of the additional transport is on. In this case, with the sequential transfer of business longest from level 21 to level 22, the role of the bundle builder is performed by the emphasis 34, transferred to the operating position IX.

In the considered variant, with the specialization of the cutting unit 8 on the sawing of the firewood, some units of the plant are superfluous. This is tray 10, cross conveyor 18 and longitudinal conveyor 19.

Along with the business length longing in this variant, at level 22, also, wood logs as a whole, first of all, thin and hardwood, which are transferred one or two 2-3 times or more, are transmitted without stopping from level 21 to level 22.

Option 3. Recycled medium thickness and thin logs of mixed breeds as well. In this case, the line should cut a significant amount of short logs.

In this variant, the operation of the installation is to a large extent similar to its operation for variant II, but with the only difference that at the level of 22, only a short-cut, an additional receiving table, an additional sorting conveyor located below the additional receiving table, is located. transverse outfeed conveyors and two distributor valves, the additional longitudinal feed conveyor being installed in series with the main one along its longitudinal axis and under the main reception table, the second razkhemny unit and an additional reception table smon

level logs, and since the level 21, they are successively complemented one by one or by packs of business and wood longest and thin logs, and at level 21, along with the opening of business logs of medium lengths, some short logs can also be produced.

Moreover, as in option II, in this embodiment at level 22 it can.

mainly, hardwood sawdust logs are being cut.

Option 4. Mainly, small whips are recycled. In this case, when using all known methods, the performance of the chewing sorting lines is significantly reduced. That is why simultaneous cutting of the same assortments is carried out both at level 21 and at level 22, but at the last one predominantly packs the feed and opening of the most fine-grained hpyyut.

The proposed device makes it possible to increase the productivity of cutting - slugging and - sorting during the processing of the predominant part of thin and hardwood timber.
