the third is accomplished by synchronizing the rotation of the drive shafts with radial grippers in such a way that the grip does not come into contact with the boards located in the two adjacent stops of the overload conveyor 5, i.e. during the time; to move the board to two hiar. stops, the gripper rotates clockwise from the upper branch to the right of the axis of the tilting movement to the upper branch to the left of the axis of the tilting device along the movement of the conveyor 5. In series with the tilting devices 1 I, the roller table 13 is mounted, which is made similarly to the roller tables 8 and 10, Which is installed on the left side of the conveyor 5, the vertical nila 14, designed to form the length of the entire board.

The sorting mechanism includes a conveyor 15 with receiving bodies in the form of stops fixed to the ends of the tube with equal tongue and having an L-shaped shape. (The speed of movement of the stops of the conveyor 15 is synchronized with the speed of movement of the conveyor 5's levels, as a result of which the boards from the co-ceiver 5 are intercepted by the stops of the conveyor 15. Under the conveyor 15, three storage tanks AND are installed in series with support sites. In the storage nerve, the landing platform Tilting the board for transferring the boards is carried out by means of hinging the bottom from one side to the vertical wall of the hopper and having a hydraulic cylinder (not shown) for turning nia1a relative to the horizontal plane downwards. In the second and third tips, the supporting platforms are made in the form of cross-sectional roller reversing conveyors 17 and 18 releasing the second and third drives, respectively. On the left side of the conveyor 17 to the left of the line is a cumulative conveyor 19, under the quality assessment mechanism - an accumulation conveyor 20, to the right of the “t line — an accumulation conveyor 21. On the right side of the conveyor 18, to the left of the line, there is an accumulation conveyor 22, and to the right of the line is an accumulation conveyor 23.

Accumulation conveyors are made in the form of longitudinal vertically closed chain conveyors arranged parallel to each other. They are located on the napa, i.ely, along the longitudinal axis of the line, and extend beyond the transverse dimensions of conveyors 5 and 15 by an amount equal to the maximum length of the board. The rollers of the reversible conveyors 17 and 18 are made with screw thread, so that the boards are dropped when they are stuck into fixed stops (not noKa3atibi) installed at the ends of the conveyors.

Under the cross roller reversing conveyors 17 and 18 and in parallel

he installed a non-intermediate conveyor in the form of a roller table 24, in the middle of which, on one side, under the conveyor 15, an irregular conveyor 25 is installed for the one-time delivery of boards. A portion of the roller table 24, located a1a c in front of the transfer conveyor 25, is made with the possibility of rotation around an axis to form a tray in front of the conveyor 25 to ensure reliable transfer of the boards. The rollers of this part of the roller table are mounted on a frame that is hinged to the base of the line on the right side. On the left side of the frame there is an actuator, for example, a hydraulic cylinder (not shown), by means of which the left side of the frame is raised above the horizontal plane to form a tray in front of the conveyor 25. Below the transmitting conveyor 25 under the conveyor 15 are located the first drives 26 and the second drives 27 made with folding heads.

The bag forming mechanism includes successively located by-pass conveyor 28 installed under accumulators 26 and 27, piecewise conveyor 29, marking conveyor 30, between which chains there is a vertical marking roller table 31, followed by a marker of 32 vertices on the left side of the conveyor 30 . Behind the marker 32 ver-njHHbi, between the chains of the conveyor 30 of the marking, there is a roller conveyor 33 of markings, followed by a marker of 34 komls located on the right side of the conveyor 30. Behind the conveyor 30, a paver 35 is installed, intended to form a transport bag 36 according to the results of processing the drying bag 37.

Lini works as follows.

The susceptible package 37 is received by conveyor I, on which up to four packages can be simultaneously, fed to elevator 2, by means of which the elevation and inclination relative to the vertical axis is carried out at an angle providing gravitationally layer-by-layer disassembly of the package 37 to form a carpet of sawn timber from layers on the transfer conveyor 3. The conveyor 3 moves the lumber in the transverse direction to the conveyor 4 of the piece by piece. The radial grippers of the drive shaft of the conveyor 4 release the boards one by one into the stops of the overload conveyor 5. When moving in the transverse direction by means of the overload conveyor 5, the boards enter the assessment and facing areas of the butt ends, where they are turned over by the turner 6 around the longitudinal axis, which assesses the quality of the butt part of the boards, determines the place of the butt end of the boards and issues commands to the line control system. With further

five

Moving the board is lifted above the working branch of the conveyor 5, approaching the rollers of the roller table 8, butt the butt, and begins to move simultaneously with the cross in the longitudinal direction. The stops of the conveyor 5, when rotated, do not prevent the board from moving in the longitudinal direction to be set in the facing position. A butt saw 9 carries out () the length of the butt part of the board, after which the plank enters the roller table And), where it is longitudinally displaced, left to align with the apical end face.

Upon further movement by the conveyor 5, the board enters the quality assessment zone and determines the location of the tops of the apex. By means of tilters 11, the vertex sawn timber is turned around the longitudinal axis in front of the workplaces of 12 quality controllers, which

Depending on the presence of defects, the quality of the entire board and the place of facing of the vertical part are determined and commands are entered into the line control system. These commands in the tracking system accompany the pilomatrix until you issue control signals to reset them to one of the drives. With the roller conveyor 13, the board is raised above the conveyor 5 and, simultaneously with the transverse displacement, moves to the left in the longitudinal direction to the position for facing the apical part, which is performed by the saw blade 14. Thereafter, the board enters the L-shaped stops of the conveyor 15 of the sorting mechanism, the speed of which is synchronized with the speed of the conveyor 5 assessment quality va. In this case, the sequence of further operations depends on the quality of a particular board.

Qualitative group of lumber, the number of which is the greatest (for example,.

0, when processing spruce planks — unskilled, pine — 4th grade) is sorted by length, for example, in accumulators x 26 of the first group. The remaining quality groups of sawn timber are fed to the respective drives of 16 quality

5 groups For example, when processing spruce sawn timber, a board of the 4th grade will go to the first drive 16, a board of the 5th grade will go to the second drive 16, and a board according to HO (UG 8486-66 - to the third drive 16 quality groups. In the first drive, Mi accumulates 90–120 minutes to 150–20 (boards, a folding bottom opens, and boards fall on a chain of accumulative conveyor 20. Lumber in the second and third accumulators 16 can also accumulate 15-20 pieces each with the reversing conveyors off 17 and IS, and then move when these pipelines are turned on in seconds When constantly connected, conveyors 17 and 18 of the board are moved in the same way to the human side, for example, boards of the 5th grade to the right by the conveyor 17 to unor, but the GOST 8486-66 is internal conveyor 18. Up to the stop. Since the rims of the roller conveyors 17 and 18 are screwed, the lumber coming into contact with the stop installed at the end of the conveyors is dropped into the accumulators. Thus, lumber of the 4th grade goes to the cumulative conveyor 20 without longitudinal change, lumber of the 5th grade goes to the cumulative conveyor 19 with a longitudinal movement equal to the maximum length of the board, and sawn timber according to the same GOST 8486-66 - nominal movement - to the accumulation conveyor 23.

Thus, when processing, for example, lots of spruce lumber, gradeless lumber will be sorted according to length in the accumulators 26 of the first group, lumber of the 4th grade of all dachas will be accumulated on the accumulation conveyor of the 20th, 5th grade - on the the final conveyor 19, and sawn timber of all lengths according to GOST 8486-66 - on the bottom of the conveyor 23. The accumulation conveyors 21, 22 and tips of the second group are free, that is, they do not have sawn timber and they are prepared for immediate reception of sawn timber other section or childbirth.

As the amount of lumber accumulates in any of the accumulators 26 of the first group, sufficient to form a trans-port package, the bottom of the loosener folds and the lumber is poured onto the bypass conveyor 28, through which they are delivered to the conveyor 29 and delivered to the stops of the chain conveyor 30 marking. Moving simultaneously with the marking conveyor 30, the marking end rolls 31 align the top end with the longitudinal movement of the non-materials to the left, which is then marked by the back alignment mark 32. After marking the top, the leveling with the roller table 33 of marking the butt part of the sawnwood is performed during longitudinal movement, which is then marked by the marker of the butt 34. The marked sawn timber does not reach the packer 35, where the forming of the overpack 36 is formed.

When processing sawn timber of another section or breed, the operation of the line proceeds in a similar way using storage units 16 for quality groups, storage conveyors 21, 22, and storage units 27 of the second group. First, simultaneously with the processing of sawn timber

Goy section or breed is the marking and packaging of all sawn timber, in our example - gradeless, located in the accumulators 26 of the first rpytnibi. Then, from the accumulation conveyor 20, lumber (in our example of the 4th grade) is fed onto the rotary part of the intermediate conveyor 24 installed opposite the transfer conveyor 25. The left side of the frame with rollers rises, for example, with a hydraulic cylinder, and the boards gravity roll with the roller table and the transfer conveyor 25, the piece is fed into the free stops of the sorting conveyor 15, by means of which they are sorted by length using drives of the first group. When the lumber from the intermediate conveyor 24 is sorted by length, the pivot section is horizontal and the next batch of boards from the final conveyor conveyor 20 again enters the transfer conveyor 25, its pivot section rises again and the boards are dispensed until the storage conveyor 20 is completely free. Pos barely sorting by length, these sawn timber are also labeled and packaged into a transport bag 36. Then from an accumulation conveyor 19, sawn timber is an intermediate conveyor 24 receives at its rotary portion and transmitting kon0 Weier 25 but the lengths are sorted in the x accumulator 26 of the first group are signed and batched. Similarly, the processing of sawn timber located on the collecting conveyor 23 is carried out. Thus, on the line is carried out

5 simultaneous sorting by length, marking and packaging of lumber of two sections or breeds. The duration of this process is 50-100 minutes. After this, the accumulators 26 of the accumulation conveyors 19 and 23 are released and the line is prepared for changing the sections of the sawn timber to be processed.

The proposed line allows simultaneous processing of sawn timber of two sections or of rocks with their minimum longitudinal movement. The capacity of the line is increased by 3-5% due to the minimization of time for the changeover of the line and the minimum longitudinal movement of lumber, eliminating the rerun

Q operations of the technological process (part-time delivery, packaging, transportation).
