Description

The invention relates to a technique of applying paint on the longitudinal edges of panel products, namely, devices used in the door door painting method by filling and rolling with elastic rollers, and can be used in the manufacture of table wood products of the woodworking industry.

A device for coloring the longitudinal edges of the door panels is known, comprising a transport conveyor and elastic rollers mounted vertically on pivot arms on either side of the transport conveyor 1.

The disadvantages of the known device are the uneven coloring of the edges of the doors due to the unregulated pressing force of the paint rollers against the edges of the doors, especially when the width of the painted doors decreases, and low operational reliability, as when the door leaf is displaced relative to the longitudinal axis of the transport conveyor and when there are gaps between the doors painted products jam the doors or break mechanisms.

The purpose of the invention is to improve the quality of paint and operational reliability.

The goal is achieved in that the device for painting the longitudinal edges of the door panels, comprising a transport conveyor and elastic rollers, vertically mounted on the hinged levers on both sides of the transport conveyor, is provided with copy rollers with a diameter smaller than the diameter of the rollers mounted in vertical planes in front of the rollers along the way. moving the door panels on the hinged levers, parallel to the levers of the rollers and connected with them, while the levers on both sides of the conveyor are connected through rods zhinoy stretching and provided with stroke limiters.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one.

The device consists of brackets 1 mounted on the frame 2 of the transport conveyor 3. On the brackets the arms 4 and 5 are hinged, forming pantograph systems that have copy rollers 6 and elastic paint rollers 7. The levers located on both sides of the conveyor are connected by a bar 8 and spring 9 stretch. For dimensional adjustment of the device for painting doors of different sizes, brackets have holes and a finger 10, which limits the movement of the levers.

The copying rollers and paint rollers contact the longitudinal edges of the doors by spring force, and the paint roller is pressed against the surface to be painted by elastic deformation of the elastic roller, the value of which is constant (for painting doors of any width)

and is from the ratio

.

where h is the value of roller compression, mm;

D is the diameter of the paint roller, mm; d - diameter of the copying roller, mm. The device works as follows. The door leaves 11, when moved by the transport conveyor 3, with their longitudinal edges come into contact with the copy rollers 6, and then with the paint rollers 7, which, by virtue of their elasticity, compress the edge of the door and, rotating simultaneously with a speed equal to the speed moving the web, rolling paint on the edge of the door. With this spring

5 9 through the rods 8 compress the pantograph systems, creating a constant contact of the copy rollers with the painted surfaces, and due to the difference in the diameters of the copy rollers and paint rollers, the latter are compressed evenly and with

 constant edge force of doors of any width.

After the product has passed, the rollers 6 and rollers 7 come out of contact with the surface to be painted and under the action of the spring 9 return to their original position until the levers 4 rest against the limiting pin 10.

Setting up the device for painting doors of another size (other width) is quick and easy. For this

it is enough to press the levers 4 and 5 with your hand and transfer it to the other, required by conditions, opening of the limiting pin 10 on one and the other side, observing symmetry to the longitudinal axis of the transport conveyor.

5 The use of the proposed device in the pass-through type lines, which work by the method of filling and overlapping paint, allows to paint both longitudinal edges of the doors evenly without gaps and eliminates cases of mechanism breakdowns, ensuring the operational reliability of the device operation, without using special guides.
