The invention relates to the woodworking industry and can be used in enterprises,.

producing plywood and wood plastics; the foot creates a vacuum, the size of the plastics.

The purpose of the invention is to increase productivity and reliability.

Fig. 1 shows a device, a plan view (the basic scheme); on Q figure 2 - section aa in figure 1; figure 3 - section bb in figure 1; on figa - section bb In figure 1.

The veneer assembly apparatus consists of lifting tables 1, above which a sheet of veneer is fed and fed to a shaft; dismantlers of a stop of vacuum unit 11 are located. From rolls, a sheet of type 2 is taken up of a dispenser. barrier-stop 13.

The go is controlled by a flap 4.

The sheet of veneer 30 is sucked into the role of the gang 5 and fed to the feed rollers 7, which transfer the sheet to the live rolls 6. The roller conveyor 6 brings the sheet to the stop 8, after which the stop 9 presses the sheet to the stop 10, i.e. orients it in space.

At the required time, stop 8

ku 4, regulating the vacuum created by the fan, and driving rolls 5.

A continuation of the roller table 5 is the roller table 6 with the feed rollers 7. The movable stops 8 limit the movement of the veneer sheet along the fibers, and the movable stops 9 orient the sheets of veneer relative to the fixed stops 10 across the fibers. The glue rollers 11 apply glue to both surfaces of the veneer and transfer it along the roller table 12 to the movable stop 13. The stacker of the veneer smeared with glue 14 takes the veneer from the roller table 12 using rods 15, brings the veneer up to the stop 16 .. and the coated sheet of veneer is laid on the two-position carriage 17. The carriage moves in the guide rollers 18, the stop 19 retains the sheet of veneer during its laying. Dry veneer sheets are laid either on the on-off carriages 20 or on the retractable supports 21 (FIG. 3). Movable stops 22 and 23 and fixed

24 orient sheet veneer over the collected feet. The pusher 25 with its clamp 26 fixes the sheets of veneer on the collected feet.

The device is operated from the console 27. The removal of the collected feet is carried out by the drive roller tables 28 and 29. The veneer sheets 30 are disassembled from the foot 31.

Device assembly stop veneer works as follows.

Laying in the foot of sheets with glue applied on them (Fig. 1-3). Lifting table 1 sets the upper level of the foot 31 in the specified

position and keeps it constant.

The veneer sheet is fed to the rollers 11. From the rollers, the sheet is received by the roller table 12, which is brought to the stop 13.

The go is controlled by a flap 4.

The sheet of veneer 30 is sucked into the roller table 5 and fed to the feed rollers 7, which transfer the sheet to the roller table 6. The roller table 6 brings the sheet to the stop 8, after which the stop 9 presses the sheet to the stop 10, i.e. orients it in space.

Upon command, the stop 13 is folded back, the end of the sheet is picked up by the bar

15player 14 and the sheet is transported to the stop 16. When approaching the stop

The 16 rod 15 (Fig. 2) is lowered and the sheet is placed on the guide carriages 1-7.

When the carriage is displaced per step, the veneer sheet is transferred and set above the foot, the second position of the carriage 17 is then set in the initial position for receiving the next spread sheet. After moving the carriage, the stop 19 extends, which determines the position of the sheet above the foot

-

across its fibers. When the carriage reverses, the veneer sheet rests against the stop 19, and the base of the carriage 17 comes out from under it and the sheet is laid on the foot (Fig. 3) at the same time another veneer sheet laid on the second 0 position of the carriage is installed above the second foot.

 Thus, for each stroke of the carriage 17, one sheet of plastered veneer is laid on the first foot, and the second sheet is placed above the second foot.

Laying in the foot of dry veneer sheets (Fig 1, 3, 4).

and keep them constant.

The fans of the 3 dismantlers stop 2 create a vacuum, and the dampers 4 set the required value.

The veneer sheets in the extreme feet are sucked into the live rolls 5 and are transferred using feed rollers 7 with rollers which are brought up to 6, 22.

A sheet of veneer from the middle foot is installed by a vacuum breaker over the assembled foot and placed on sliding supports 21. The carriage 20 shifts by one step, with its stops moves the sheet of veneer from the rollers of the roller table 6 and takes it to its guides. In the extreme position of the carriage, the sheet is positioned above the collecting foot and is oriented relative to it by the stop 23, the second position of the carriage at this time is set at the second extreme vacuum pick-up and can receive the next sheet.

Thus, two sheets of veneer are placed simultaneously over the collected foot.

The pusher 25, with its clamping 26, presses both sheets of veneer to the foot, after which the carriage 20 returns to its original position, and the supports 21 are folded and both sheets of veneer are laid on the foot.

In accordance with the above, in one stroke of the carriage, two 30 sheets of veneer are laid on the foot, and the second position of the carriage

set to receive the next sheets.

The line is controlled from the console 27.

1 Thus, when assembling three-layer plywood, in one stroke of the carriages, one sheet of plywood is put on one foot, and two 10 sheets of dry veneer are put on the other foot.

Claims (1)

After the collected foot has reached a predetermined height, the roll tables 28 and 29 are turned on, and the foot is transported outside the line. A device for assembling a stop veneer, including lifting tables, glue rollers, a vacuum-type veneer stop dismantler, a carriage, a spar handler and roller tables, characterized in that, in order to increase productivity and reliability, the device is equipped with two carriages and stops for the orientation of the veneer sheets, Moreover, all the carriages are made in two positions and are located under the stops and under the stacker with the possibility of reciprocating movement 5 and the stops are located in the zone of the collected veneer stop.
