(54) INSTALLATION FOR PAINTING OF LARGE-SIZED PRODUCTS

(57) The invention relates to installations for applying a liquid by spraying onto the surface of an article and can be used to apply paintwork on large-sized articles. The aim of the invention is to expand the technological capabilities of multilateral painting products. This is achieved by the fact that the installation is equipped with two drive carriages mounted for movement across the chamber, mounted on vertical carts with guides mounted on them with the possibility of reciprocating movement of spray gun carriages and movement actuator. The installation allows you to improve the performance and quality of painting large-sized products. 2 Il.

ABOUT

f

The invention relates to installations for applying a liquid by spraying onto the surface of an article and can be used for applying paints and varnishes on large-sized articles by means of pneumatic, electro-electrostatic and electrostatic spraying.

The aim of the invention is to expand the technological capabilities of multilateral painting products.

Figure 1 shows an apparatus for painting large-sized articles; figure 2 - section aa in figure 1.

The installation comprises a chamber 1 with two edges 2 for the passage of articles 3 and a means for moving articles 3 along chamber 1 in the form of carts 4 with a chain pusher 5. Vertical guides 6 are placed on the side walls of chamber 1, a horizontal guide is installed in the upper part of the chamber 7. The horizontal guide 7 and the vertical guide 6 are mounted with the possibility of reciprocating movement of the carriage 8, 9 with the spray guns 10, 11. The carriage 8, 9 are interconnected by a flexible link 12 and have a movement drive made in de hydraulic drive 13 with link 14.

The installation is equipped with two driving carriages 15 installed on the guides 16 with the possibility of moving across the chamber 1. On the carriages 15 vertical guides 17 are fixed.

The guides 17 are mounted with the possibility of reciprocating movement of the carriage 18 with the spray arms 19.

Trolleys 15 have a hydraulic actuator 20 and backstage 21, connected by flexible suspensions 22 with carriages 18.

In the chamber 1, stops 23 are installed with the possibility of interaction with end-1-1 and switches 24 and the stop 25, which interacts with the end switch 26,

Chamber 1 is equipped with a platform 27 with an injection system 28 installed on it with air ducts 29 and louver air ducts 30 and an exhaust ventilation system 31 with air ducts.

The installation works as follows.

The product 3, mounted on the carriage 4 by the chain pusher 5, is fed to the chamber 1. When the end switch 26 interacts with the stop 25, the drive of the chain pusher 5 is turned off and the product stops at the coloring position. The exhaust ventilation system 31 is turned on and the product 3 is blown with air and cooled by the injection system 28 and exhaust ventilation 31,. After the required time specified by the relay, the injection system 28 is turned off and the hydraulic drive of the 20 carriages 15 is turned on.

When moving the carriage 15 across the chamber 1. The stops 23 act on the limit switches 24, which. include the supply of paint to the spray guns 19; The carriages 18 reciprocate with the wings 21 and the suspensions 22,

After painting the sprays 19 on the end walls of the product 3, the carriage 15 stops at the side walls of the chamber 1, the stops 23 act on the limit switches (not shown), which turn on the paint to the sprays 10, 11, the hydraulic actuator 13 turns on, and the carriages 8, 9 begin to make reciprocating movement along the rails. The chain pusher 5 is turned on and in the process of moving the cart 4 with the product along the chamber 1, the side walls and the roof of the product 3 are painted simultaneously,

The shutdown of the entire installation is effected when the stop 26 is exposed to the limit switch 25 after the end of the painting of the entire product.

The use of the proposed installation allows to increase the productivity and quality of painting of large-sized products.
