(54) INSTALLATION FOR PAINTING PRODUCTS

The invention relates to process equipment for painting products. A known device for coloring groats of large-sized products, comprising a painting chamber separated by a partition and a supply chamber urged over it, a ventilation device with a lower air suction and a working platform. In this installation, in order to reduce the air flow to the ventilation, the working platform and the partition wall, the conveyor with the perforated section is installed with the possibility of simultaneous movement in one direction and the curtains with a window for air passage l. The disadvantage of this installation is that it does not provide satisfactory sanitary and hygienic working conditions of the worker. Closer to the described invention is a device for painting products, containing a loading-unloading / loading mechanism, a painting chamber, a conveyor and a ventilation system 2. The disadvantage of this installation is that it cannot be used for double-sided painting. products having a flat shape. The aim of the invention is to provide a non-lateral coloring of flat products from the same workplace. This goal is achieved by the fact that the installation for painting products, containing a product loading and unloading mechanism, a painting chamber, a conveyor and a ventilation system, is equipped with a satellite frame with a device for rotating the painted product made in the form of a rigid closed frame mounted on the satellite frame. by means of sub-hinges and a spring-loaded retainer mounted on one of the sides. The invention is illustrated in the drawings, where FIG. 1 depicts a plant for coloring in a sjufilny projection; in fig. 2 satellite frame in frontal projection; FIG. 3 - section aa and takeaway 1.

The painting unit contains a loading-unloading mechanism 1, consisting of two racks 2 with lodgments 3, a coloring chamber 4 with a spraying machine, equipped with a closed conveyor 5, and two parallel branches 6 and 7 connected between each other by barbells 8 fitted with lodgements 9, on which the satellite frame 10 is hinged, consisting of a suspension bracket 11, in which, using a bearing hinge 12, a rigid closed frame 13 is fastened, a lever 14, which removes the lock 15 from engagement with the rigid closed frame 13, a spring 16, which introduces in the hook A clamp with a rigid closed frame 13 with the lever 14 lowered, clamps 17 that secure the product 18 to the rigid closed frame 13.

The painting machine works in the following manner.

Before painting into the rigid closed frame 13 of the satellite frame 10, clamps 17 secure the product 18 (clamps 17 are technological, the design of which is determined depending on the design of the product 18).

The satellite frame 10 with an unpainted product 18 is fed by the upper transport to the installation of the painting of products and is lowered into the cradle 3 racks 2 of the unloading-unloading mechanism 1.

The drive of the loading-unloading mechanism 1 and the pillar 2 is turned, turning together with the satellite frame 10, is lowered into the cradle 9 of the conveyor 5. The drive of the conveyor 5 is turned on and the frame-junction 10 moves one step through the opening into the painting chamber 4. The worker, located outside the painting chamber 4, produces one side painting1 of the product 18. Suction of harmful colorful dust is carried out by exhaust ventilation, while clean it is taken from the workshop through the opening of the painting chamber 4.

To paint the back side of the product 18, it is necessary to turn the rigid closed frame 13 relative to the suspension 11 to an angle of 18О. To do this, the worker presses the lever 14, which rotates, disengages from the rigid closed frame 13 retainer 15, compressing the spring 16. Thereafter The worker turns the balanced rigid closed frame 13 with the product with the angle 180, lowers the lever 14 and the spring 16 engages the locking pin 15 into the swiveled frame 13. The worker paints the back side of the product 18.

The full color of the product 18 is connected to the conveyor drive 5 (forward) and the satellite frame 10 with the painted product 18 is moved in the opposite direction to the schag from the spray booth 4 to the area for removing the satellite frame 10 with painted

the product 18 from the conveyor 5 by the loading-unloading mechanism 1 (the unloading mechanism 1 with the uprights 2 and the cradle 3 after loading the satellite frame 10 into the cradle 9 of the conveyor 5 was left in the rightmost position and is ready to make a reverse rotation, as shown in FIG.

After the conveyor 5 is completely stopped, the drive of the loading and loading mechanism 1 and the RACK 2 is turned on, turning the bed frame iS to the satellite frame 10 with the cut product 18 and turning it to the extreme left position in the removal zone with the top transport of the frame satellite 10 with the painted product 18. After the loading-unloading mechanism 1 is completely stopped, the satellite frame US with the painted product 18 is removed and carried by the upper vehicle for drying the paint and varnish coating. The cycle described above is repeated.

The use of this invention will ensure the coloring of large-sized flat products from one workplace outside the painting booth and satisfactory sanitary and hygienic working conditions.
