ABOUT)

The invention relates to spray coating devices for liquid materials on the surface of products and can be used for painting cars and other large-sized products.

The purpose of the invention is to provide the possibility of accelerating the painting process by combining the operations of applying paint on the end side and top surfaces of the product.

FIG. Shows a camera for dyeing large 1x items; Fig 6 2 - section aa on j in fig 3, section bb on fig.c on - section bb in figure 2,

The chamber contains a frame I with two openings in the end walls 2 for the passage of articles 3 and guides 4 for its longitudinal movement,

In the chamber, on the guide beams 5 with supports 6, a U-shaped frame 7 is installed with vertical rows of nozzles 8 at the side walls of the frame 3 and horizontal of a number of spreaders 9, perpendicular to the guides 4, Pai ja 7 has a movement drive along the guides four,

The frame drive, 7 turns on the engine 10 with the gearbox 1 and connected to the valuable shaft 52 mm by the shaft} 3 with rollers 14 "mounted on guide beams 5 In the chamber on the extreme supports 6, made in the form of S1x, carriages are installed 15 and 16 with horizontal rows of sprays 17, 18 located at the ends of the walls 2 perpendicular to the guides 4,

The carriages 15 and 16 have vertical movement drives. The carriage drive 16 includes a gear wheel 20 fixed on the supports 19, mounted with the ability to interact with the rack rail 21. At the ends of the shaft gear wheel 20 there are sprockets 22 and 23 connected by chain conveyors 24 and 25i, with the carriage 16, Carriage drive

15 has a similar implementation. The coloring chamber works as follows.

in the way

In the initial position, the U-shaped frame 7 is installed at the left end wall 2, with the carriage 15 and

16 is in the extreme upper position, and the rack and pinion 21 engages with the drive gear shaft

the vertical movement of the carriage 15c

The painted product 3 is introduced through the left opening of the end wall 2 into the chamber. After the product 3 is installed in the painting position, the drive of longitudinal movement of the U-shaped frame 7 is turned on and the paint is simultaneously supplied to the spray guns 8, 9 and 17

In the process of moving the U-shaped frame along the product, the side and top surfaces of the product are painted with spray guns 8 and 9,

Simultaneously with the movement of the frame 7 of the gear, the rail 21 rotates the gear shaft of the vertical movement drive of the carriage 15 and moves the carriage 15 down through the chain conveyor, while the nozzles 17 color the left end surface of the product 3,

When the carriage 15 reaches the extreme lower position of the rack and pinion, the rack 21 is disengaged from the gear shaft and at the same time the paint stops at the spray gun 17,

When approaching the U-shaped frame 6 to the right end of the gear 3 product, the rack 21 engages with the shaft-shaft 20 of the vertical movement drive of the carriage 16 and, through the chain conveyor 24 and 25, moves the carriage 16 downwards,

At the same time, the paint is supplied to the sprayers 18 and the second end surface is painted

products,

I

When the carriage 16 reaches the lowest position, the coloring of the second end surface of the product ends and the coloring of the side and top surfaces ends. The ink supply to the spray guns 8, 9 and 18 is stopped and the frame 7 returns to its original position. When moving to the left of the frame 7, the carriage 15 and 16 are moved to the highest position and the camera is prepared for coloring the next product.

The invention makes it possible, due to the stationary position of the product during the coloring process, to improve the uniformity and quality of the coloring.

Combining the painting operations of the face, side x and top surfaces of the product speeds up the painting process

The use of the invention in car-building plants will increase the productivity of paint

works by automating the painting of the exterior surfaces of cars, reduce energy costs and operating costs.

Claims (1)

Invention Formula Since, in order to enable the coloring process to be accelerated by combining the coating operations on the end side and top surfaces of the product, it is provided with a second driving carriage with a horizontal row of distributors mounted on it perpendicular to the guides the frame is made with a horizontal row of splitters, is mounted for movement along the guides to is equipped with a drive for moving and a tooth.
