However, the known device has a complicated design; / cc does not have sufficient bitingness, which does not allow its machine to use it; - for assembling heavy and large-sized 55 pkryashek and does not provide for the required quality of rolling tires.

With the purpose of a full-scale design and improvement of the quality of the proposed equipment on each harness, the levers of the mechanisms of rolling and the MexamisMOB turn-over of the chafer ribbon are hinged by means of common axes on the slide, which are mounted on the carriage with the possibility of moving-25

shadows perpendicular to the movement of the last yy; -ravl: AI. the drive of the slide is made in the form of a hydraulic cylinder equipped with a detachable spacer mounted on the rod.

FIG. 1 Goosako proposed device, nlTT-vKaTK tsl 5. general view; in fig. 2 the same, via pacifier; p. and fig. 3 - pneumohydraulic device shhek.

The proposed rolling device consists of identical groups of mechanisms with a common drive from the electric motor 1 through a worm gear 2 and screw-nut transmissions mounted on carriages 3. mounted on flat guides 4 of bed 5. Guides 4 are located angled to the horizontal plane.

Lever 6 with a roller 7 for stitching and a lever 8 with a roller 9 for turning the chafer are mounted by means of common 10 on the slide 11. The slide 11 is mounted on the carriages 3 for movement in the direction perpendicular to the movement of the latter. On the slide 11, the pneumatic cylinders 12 and 13 of the levers 6 and 8 are hinged. The slide 11 is moved by the hydraulic cylinder 14. To replace the device quickly, the removable spacer sleeves 15 are installed on the hydraulic cylinder rod 14.

To control the device, there are limit switches 16-21 and a system of hydraulic and pneumatic automation, containing a pgo vertical hydraulic valve 22 with electromagnets 23 and 2.4, air distributors 25 and 26, pressure regulators 27-29, another 30 valve and 31 and a reversible hydraulic spool 32.

The pepper started working in the initial position of the carriage device 3 is reduced to the middle of the assembly drum, and the slide 11 with the rollers 7 for rolling and the rollers 9 for turning the chafer is in its lowest position.

When the electromagnet 23 of the reversing hydraulic spool 22 is turned on, the slide 11 is rapidly supplied to the assembly drum to the end switch 16. At the same time, air from the pneumatic network through the air distributor 25, pressure regulator 27, air distributor 26 and throttle 30 is fed into the rod end of pneumatic cylinders 12. Rollers 7 pressed against the press surface. The same limit switch 16 includes an electric motor 1. The carriage 3 is diverted from the center, using rollers 7, rolling the carcass of the assembled Tire. The carriages move to the final switch 17, from the signal of which air from the pneumatic network through the air distributor 25, pressure regulator 28, air distributor 26 to the throttle 31 is fed into the piston cavities of the pneumatic cylinders 12, and from their rod cavities the air enters the atmosphere through the throttle 30 and air distributor 26.

The rollers 7 move away from the pressable, surface to the initial position. From the same end switch 17, the solenoid 24 of spool 22 is actuated. At the same time, the oil from the hydraulic pump through pressure regulator 29 and reversible bars and 22 and 32 enters the hydraulic cylinder rods. Drov 14, and from the piston cavities goes to drain through the spool 22. Slides 11 return to the starting position. The carriages 3 move further to the end switch 18. The roller rollers 7 rotate around the axles 10 and occupy the initial position for rolling the bead side of the tire. Air from the pneumatic circuit through the air distributor 25, pressure regulator 27, air distributor 26, and throttle 30 enters the rod strips-

These pneumatic cylinders 12, and from their piston cavities go out into the atmosphere. Then the electromagnet 24 of the spool 22 is turned on and the slide 11 is accelerated to the assembly drum to the limit switch 1 9 which turns on the electric motor i dd

moving the carriages 3 to the center of the drum to the limit switch 17. Then the levers 6 are rotated until the rollers 7 come into contact with the tire bead. In doing so, air is supplied to the piston cavities of the cylinders 12, and the rollers are pressed against the tire bead to be rolled on.

The slide 11 slowly returns to its original position until the limit switch 20, while rolling the bead. Then, the limit switch 20 turns on the electric motor 1, and the carriage 3 converges towards the center to the limit switch 21. Similarly, the rolling of all layers of the tire carcass is carried out. The last group of layers rolls in toward the axis of the assembly drum.

Then, the chafer ribbon is applied, which is rolled up by the rollers 9 by the toe of the bead. The carriages 3 are then set to the end switch 17. Then the pneumatic cylinders 13 are turned on, which turn the levers 8 with the rollers 9 around the axes 10 to the assembly drum.

In the reverse slow motion, the slide 11 turns the chafer ribbon by the toe of the bead.

Rolling of the running part of the tread and sidewalls is carried out similarly, but with variable pressure. The change in pressure is achieved by switching the pressure regulators 27 and 28.
