(54) COLOR UNIT

 .., V. - -:

This invention relates to a railway ;; transport and can be used for coloring rolling stock. :

Lime plants for painting railways), containing spray guns on the walls of the hull and lifting platforms for accommodating workers with spray guns 1.

Closest to the invention is a color dry-aggregate unit comprising a body, guide beams, paint-6 (paint, mounted on movable carriages with a drive, alternating spray guns in paint and paint painted surfaces 2.

However, in a well-known painting unit, safety is not ensured when painting the end walls of a car, which is necessary for accidental (emergency) impact on spray guns of the next painted car, as a result of which unit breakage is inevitable, and when painting a product in an electrostatic field, breakdown on the hull and fire.

The aim of the invention is to increase the safety of work when painting the end walls of the car.

 ; W

This is achieved by the fact that in the proposed device, the ends of the beam are mounted on rollers placed on the longitudinal beams, and the carriage carrying the spray gun, with a flexible rod, is connected to the counterweight, the guide block of which is mounted on the body.

FIG. 1 schematically depicts the color coater; in fig. 2 - the same, cross section.

The painting unit comprises a housing 1, guide beams 2 on which a carriage 3 with an actuator (not shown in the figures) and a sprayer 4 are installed. The guide beams 2 with the ends are mounted on the rollers 5 placed on the longitudinal beams 6, and the carriage 3 by

5 of the flexible rod 7 is connected to the counterweight 8, the guide block 9 is secondly mounted on the housing 1. The bend of the ha 7 in the middle part is skirted by the block 10, the axis of which is fixed on the guide beams 2. The carriage 3 is fitted with a limiting 11 with a support roller 12, which stand; it falls outside the nozzles 4. On the case I and the prodbyten Sten stains and the car roofs there are stationary nozzles 13.

The painting unit works as follows. by azom /

The car for painting is fed to the zone of action of the sprayers 4 and stops. The carriage 3 with the sprays 4, by means of a drive, starts to move along the Guide rails 2 along the front end wall of the car.

The nozzles 4, moving from the upper position to the lower and back, paint the front end wall of the car.

The carriage 3 moves until it is outside the carriage. In this position, the ink supply to the spray guns 4 is stopped and the carriage 3 stops.

Then stationary sprays 13, located on housing 1, begin to work, and the carriage does not move. The side walls and the roof of the car are being painted.

How. only the car will leave the zone of action 11 1 of the splitters 13 and its rear end wall 20 will be in the zone of action of the front nozzles 4 of the carriage 3, the car will stop and the nozzles 13 will be turned off.

Then the carriage 3 begins to move in the reverse direction, and the nozzles 4 move up and down and paint the back end wall of the car. At the end of the painting, the carriage 3 stops and the device turns off. The unit is ready for painting the next car.

.In the case of the first situation, i.e. In case of accidental running over of the carriage by the sprayers 4, the system of emergency removal of splitters from the zone of movement of the carriage is triggered. After the double carriage will turn the support roller 12 to the limiter: II and will move on, together. Schm & D & p & Ytikaretka 3 together nal-. The two beams 2, which, in turn, will move on the rollers 5 along the longitudinal beams 6. At the same time, the bend 7, attached to the carriage 3, will begin to collapse from the guide block 9, and the counterweight 8 will be raised up.

As soon as the bend bar 7 is flexible, through the block 10 completely withdrawn from the guide block 9 and tensioned, the counterweight 8, rising to its highest position, will begin to pull the carriage 3 off the guides of the block 2 until the roller 12 of the stopper 11 no scrolling from the end of the moving car and the carriage 3 with nozzles 4 will not be outside the movement of the car.

The described painting unit mechanizes the process of painting the end walls of products with o6ecne4eHHe vf safety of these works and can be used for exterior painting of buses and trolleybuses.
