Description

The invention relates to the production lines of wood panels and can be used in the woodworking industry in the production of panels for low-rise wooden houses.

The circuit of the invention is the improvement of the quality of the panels.

Fig. 1 is a plan view of the manufacture of wooden panels; in fig. 2 shows section A-A in FIG. one.

The lines for the manufacture of wooden panels include conveyors of assembly 1 and feeds 2 of panels 3, section 4 for the introduction of thermal insulation composition 5 and drive 6, and equipped with a closed chain conveyor 7 installed at the exit of assembly conveyor 1 with pairwise working longitudinal 8 and transverse 9 and returnable longitudinal 10 and transverse 11 sections. The working section 8 of the conveyor 7 is part of the introduction section 4 of the heat insulating composition 5. The line is also equipped with an orientation mechanism 12 of the panels 3 and the seal assembly 13 of the heat insulating composition 5 mounted on the working section 8 of the conveyor 7, and the orientation mechanism 12 of the panels 3 is completed as carriages 14 with support rollers mounted on its longitudinal sides, lower 16 and upper 17, which are rigidly connected to each other, and mounted respectively on the front 18 and longitudinal 15 sides of the carriage 14 to fold off the stops 19. Seal assembly 13 is placed at the exit of the introduction section 4 of the heat insulating composition 5 and is designed as pads 21 spring-loaded with respect to the base 20, and the introduction section 4 of the insulation composition 5 is connected to the inlet 22 and exit 23 of the working section 8 of the chain conveyor 7. In addition, includes a conveyor 24 for removing the finished panels 3 from the introduction area 4 of the heat insulating composition 5. The panel 3 has an end opening 25 for pouring polyurethane foam.

Lini works as follows. The frameworks with panel skins are assembled, and the panels 3 prepared thus for filling with the thermal insulation composition 5 are conveyed 1 from the assembly site to the feed conveyor 2, which is equipped with an orientation unit 12 of panels 3. The panels 3 are located in such a way that their end holes vehicle side of the conveyor 1.

 In the orientation unit 12, the panels are located on the carriages 14, their position is fixed by folding stops 19,

located on the front 18 and longitudinal 15 sides of the carriage 14. The carriage 14 with the panel 3 fixed to it is moved by means of 15 lower 16 and upper 17 supporting rollers mounted on its longitudinal sides and rigidly interconnected (i.e. the carriage rolls on two rollers 16 ), to the injection area 4 of the heat insulating composition 5. On

approach to section 4, the worker turns | panel 3 in a vertical position. In this case, the panel 3 occupies a stable vertical position, since the rigidly connected rollers 16 and 17 of the carriage 14 are set in a horizontal position and the center of gravity of the panel 3 is shifted, as it were. Vertically mounted panel 3 (the end opening 25 is located in

the upper position) is brought by the working longitudinal branch 8 of the closed chain conveyor 7 to the pipeline 4 pouring polyurethane foam 5 into the cavity of panel 3. Next, the working longitudinal

the branch 8 of the closed chain conveyor 7 slowly moves the panels 3 poured to the top with polyurethane foam to the seal assembly 13.

During the movement, the polyurethane foam begins to partially cling to the panel walls, and the middle part of the mass under its own weight settles, and partially, i.e. voids are formed at the top of the panel.

This disadvantage is eliminated in the compaction assembly 13, where the panels are shaken due to the vibration of the base 20 of the platform 21. The polyurethane foam is finally compacted

It is completed from pipeline 4 at the end of the working longitudinal branch 8 of the conveyor 7. The panel is filled with polyurethane foam, and after some holding, the worker turns it counterclockwise, the panel takes a horizontal position (roller 17 again takes the upper one, and roller 16 has a lower position, i.e. carriage 14 again on

 two rollers). In this form, the panel 3 is picked up by the rollers of the conveyor 24 and transferred to the following operations. The carriage 14 moves along a closed conveyor 7 (in sections 9-11) and returns to the working longitudinal section 8 to grip the new panel 3 and feed it for wadding, pack 2472904

lotning and mending with insulating material.

The line design provides improved product quality by reducing shrinkage cavities, because filling the cavity with polyurethane foam is carried out in two stages in a vertical position.
