(54) VARNISHING AND DRYING VDT LINE

one

The image refers to furniture and woodworking abilities, in particular, to the varnishing and drying line of panel parts coated with paintwork materials.

The known line for varnishing and drying of panel products includes a feeder, a lacquer machine, means for transporting panel products, a drying chamber with a chain conveyor installed with a sinusoidal vertical motion, and suspended shelves 1 mounted on a chain conveyor.

Not enough - loading of products into the drying chamber and their unloading is carried out manually. In addition, the maximum camera occupies a large production area, and the harmfulness of hazards is difficult due to the large open apertures in the drying chamber at the places of loading and unloading panel products.

The purpose of the invention is to increase productivity.

This goal is achieved by the fact that in the line for varnishing and drying of shield products containing pi. PRODUCTS

teller, lacalinker machine, means for transporting shield products, a drying chamber with a chain conveyor installed with the possibility of sinusoidal movement in a vertical plane and suspended shelving units mounted on a chain conveyor, the drying chamber at the inlet and outlet is equipped with loading mechanisms and products loading m which contain drive and non-drive sections, installed with overlap relative to each other and made in the form of supports with fixed

15 there are paired cantilever rollers on them with half a heel of suspended floors, which are made in the form of forked hooks connected by a center of the station, and the suspension frames of the KHF RO are attached to the chain conveyor and are attached to the amp;

1 This one of the forked hooks is made of a rod made of rods, connected with each other by a side bar and more flexible with a gap relative to the tows. In addition, a drying cylinder with an abgen OJ limiter position on the spruce and guides for

30 hanging shelves.

At the same time, the middle part of the drying chamber is also fenced with shield panels that form air zones with the sections of the chain conveyor. In addition, the line is equipped with a fencing casing and exhaust valve 7 with a dionic system with suction nozzles integrated into the fencing casing.

Figure 1 schematically shows the proposed line in figure 2 - the same, in plan; on fig.Z - drying chamber in a vertical plane; figure 4 - the same in the plan; on fig.Z and

6- suspended shelf with loading mechanism in the plan; in fig. 7 shows sections A-A in FIG.

The line for varnishing and drying of panel products contains a feeder 1, a flat-bottom machine 2, a pivoting roller conveyor 3, a bar 4 (equalizer of panel products) feed conveyor 5, mechanism 6 for moving shield products, located on the supply conveyor 5, mechanism

7, located at the entrance of the drying chamber 8, the unloading mechanism 9, located at the outlet of the drying chamber 8, receiving conveyor 10, rotary roller conveyor 11, intermediate conveyor 12, belt conveyors 13 and 14, vibration grinder 15, stacker 18 furniture panel board products, 17 ventilation system, ukry: u1e 18 with built-in local suction.

The drying chamber 8 is provided with a drive 4 by a chain conveyor 19 mounted with the possibility of a sinusoidal movement, on which movable racks 20 moving along the guides 21 are hinged.

A suspended bookcase 20 consists of many brown shelves fixedly mounted on a hanger (not indicated in the drawing) with a certain distance from each other. With the help of the hinge, the stack 20 is attached to the chain conveyor 19. The distance between the suspension frames 20 corresponds to the time it takes to fill all the floats of the previous suspension shelf.

The middle section of the drying chamber is fenced with shield screens 22. The lower shelves of the suspended shelves 20 are equipped with rollers 23 in the corners. The shelves of the suspended shelves are made of two forked grippers connected in the center with a tie-rod 24.

Each of the forked grippers consists of rods 25 interconnected by a side bar 26 and spaced apart from each other at a certain distance to allow the rollers 27 of the drive and non-drive sections to pass freely between them. Forked grips are installed so that the length of the rods 25 is less than the length of the supports 28 and 29 mechanism

7 downloads (mechanism 9 unloading). The mechanism 7 for loading (unloading 9) of shield products is made of successively mounted drive and non-drive sections consisting of paired cantilever rollers 27 mounted on supports 28 and 29.

The support 28 of the driving mechanism of the loading mechanism is attached to the bed of the feeding conveyor 5, and in the unloading mechanism to the bed of the receiving conveyor 10, the support 29 of the non-driven section of the loading and unloading mechanisms to the position limiter 30 of the shields and the guide 31 of the chain conveyor 19.

The drying chamber B is equipped with a flow-through ventilation system 32 with a heater 33, the distribution duct of which is installed in the lower middle part of the drying chamber, a gas analyzer 34 and a thermometer 35.

Lini works as follows.

Furniture panel products are automatically fed by the feeder 1 individually for varnishing into a lacquer machine 2, after which they are fed to a reversing roller conveyor 3, on which the furniture panel products are turned 90 and set with the long side parallel to the bar 4 of the panel board leveler 4. . Further furniture panel board product enters the feeding conveyor 5.

With the aid of the strip 4, the shield articles are leveled before entering the loading mechanism 7. On the trimmer plate 4, there are two limit switches on the left and right (not shown in the drawing), which are included in the shield product. If one long product is fed to the loading mechanism 7, then with its edge it closes both end switches on the left and right located on the bar 4. In this case, the leveler bar goes down and the panel board goes first to the drive section and then to the non-driven section of the mechanism 7 downloads. By the limiter 30, the shield article is prevented from sagging and curving in the horizontal plane.
