9d J The invention relates to equipment used in drying paint coatings of furniture panels. The purpose of the invention is to increase productivity. Figure 1 shows a suhlshlka for furniture panels; section A-A in FIG. 25 in FIG. 2 is a section BB in FIG. 1; Fig. 3 shows a drying shelf for furniture panels. The drying shelf for furniture panels consists of a U-shaped frame 1 containing horizontal supports 2 for furniture panels, which are trough-mounted and attached to the frame by means of vertical posts 3, Frame 1 is mounted on rollers 4. The drying shelf is installed in a dryer for furniture panels consisting from the closed drying chamber 5, which in the middle part contains heating units 6 and fans 7. In the outermost parts of the chamber, vertical paired chain conveyors 8 are installed and attached to the frame of the chamber; Horizontal rails 9, supporting the upstanding rollers of the drying rack, are fitted. In the upper and lower parts of the dryer there are horizontal chain conveyors 10, also attached to the frame of the chamber. For feeding and unloading shields, the dryer is equipped with cantilever roller conveyors 11, which are separated by water. Vertical paired and horizontal chain conveyors are equipped with separate drives. Vertical paired chain conveyors, lifting the shelves using mechanical transmission, are connected to vertical paired lowering shelves of chain conveyors. Horizontal chain conveyors that move the shelves from the lifting part to the lowering one by means of a mechanical transmission are connected to the horizontal chain conveyors by means of the lowering shelves from the lowering part to the lifting part. Drying shelf works as follows. Furniture shields coated with varnish enter the dryer on the loading cantilever driven live rolls 11. The upper shelf is located below the surface of the drive console 60 of the live rolls. When the furniture board reaches the end, the shelf rises by one paired vertical chain conveyor 8 by one. Lifting the shelf is carried out by raising the rail 9, on which rollers 4 shelves are mounted, attached to the chains of a paired vertical chain conveyor 8. After lifting the shelf to one channel, the cantilevered roller conveyors 11 serve the next lacquer furniture board. The process is repeated until all the ruses of the shelves are filled with furniture panels. After lifting the entire shelf to its full height, an empty shelf is fed to the vacant space under it using the lower horizontal chain conveyor 10 to fill its furniture & boards with shields. Both sides of the dryer are filled with shelves at full height. When raising the shelves on one side of the dryer on the other side of the shelf, they synchronously lower. When the shelf at the bottom of the dryer moves by a horizontal chain conveyor to the right, the shelf at the top of the dryer is simultaneously fed to the left by an upper chain horizontal conveyor, i.e. all the shelves in the dryer make a circular motion. When lowering the loaded shelf, the lower furniture panel sits on the cantilever discharge table 11 so that the supports of the bottom rus are below the surface of the rollers of the cantilever discharge table. By turning the rollers, the furniture unit is unloaded from the dryer. The lowering of the loaded shelf is repeated until all the boards from the shelf have been unloaded. After this empty shelf, the lower horizontal chain conveyor moves in the direction of its loading. When raising and lowering shelves, furniture panels pass through drying zones. The highest temperature of the drying zone is in the upper part. The air enters the dryer from the workshop to the lower heating unit 6 and the fan 7 is supplied to both sides of the drying chamber along

furniture panels, laid on the supports of the shelf. After the passage of the first drying zone, the air enters the next heating unit 6 and

fan 7 of the second drying zone. Thus, the air gradually passes through all the drying zones, and from the top of the dryer it is thrown out.
