Description

The invention relates to equipment of the tire industry and is intended for applying lubricant to the inner surface of tires before vulcanization.

The aim of the invention is to improve the color quality.

FIG. 1 shows the device, a general view from above; in fig. 2 - the same, front view.

The device contains a centering roller 1, a roller 2, which performs the functions of the supply and selection roller for tires 3.

Adjacent to the selection roller table is a rack 4, on which a carriage 5 is mounted movably in a vertical direction, connected to a rod of a power cylinder 6 pivotally fixed on the base of a rack 4. On a carriage 5 a cylindrical sleeve 7 is mounted with a beam 9 mounted on bearings 8 The rotational drive of the rocker arm is made with the possibility of reciprocating rotational rotation of the rocker arm through 180 ° and is a power cylinder 10 connected to the carriage 5 and the rocker arm 9 by means of hinges 11 and 12 in such a way that Collar 90 ° rocker axis extending through the cylinder joints and the rocker axis lie in one vertical plane. At the ends of the rocker arm 9, the grips 13 for tires and power cylinders 14 are attached. The gripper for tires is made in the form of a slider 15 connected to the power cylinder 14 and mounted on the slider 15 of the levers 16. The slider 15 with the levers 16 are mounted inside the cylindrical body 17.

The slider 15 is connected to the rod 18 of the power cylinder 14. Adjacent to the stand 4, under one of the claws is located a cupped pan 19, in the bottom of which a spray nozzle 20 is installed associated with a lubrication system (not shown).

The device works as follows.

The tire 3 goes to the centering roller conveyor 1, where it is centered, and then goes to the screening roller table 2, which transports the tire

under the grip 13. The power cylinder 6 lowers the beam 9 from the upper position to the bottom. The cylindrical body 17 rests on the bead of the tire 3 located on the roller table 2. The power cylinder 14 moves down the slider 15 of the gripper 13, which opens and seizes the tire 3 over the side. The power cylinder 6 lifts the rocker arm 8 with the tire 3 to the upper position. Then, the power cylinder 10 is actuated: first, air is supplied to the rod end of the cylinder, the rocker arm is rotated by 90 °, then air is supplied to the piston cavity of the cylinder and the rocker arm is rotated another 90 °. The following tire 3 is fed to the selection roller 2, which is transported under the free grip 13. Then the power cylinder 6 lowers the rocker arm 8 from the upper position to the bottom, the tire is lowered onto the pan-shaped pan 19. The cylinder 14 closes the gripper 13 to remove the gripper arms from the paint zone. In the nozzle 20 a lubricant is supplied, the inner surface of the tire is painted. When painting, the coloring liquid is prevented from entering the environment, since the nozzle is enclosed in a closed space formed by a cylindrical 17, tire 3 and cup pan 19. After painting, cylinder 14 reopens grips 13. At the time of painting the tire on the other end of the rocker arm, the tire is gripped on the roller table 2 Then the power cylinder 6 lifts the rocker with

two tires up, then cylinder 10 rotates the rocker arm 180 °, as described earlier, but in the opposite direction.

The painted tire is above

the selection roller 2, the cylinder 14, the gripper 13 is closed, and the tire is fed to the selection roller 2, which takes the colored tire and at the same time feeds the next tire to the free gripper 13. Then the device continues, similarly to that described.
