A device according to claim 1, in accordance with claim that it is equipped with a second syringe machine installed coaxially with the first one.

Description

The invention relates to the manufacture of tires for pneumatic tires and is intended for assembling belt-tread bracelets for making radial tires.

A device for assembling belt-tread bracelets is known, comprising a rotary rotor with rotatable assembly drums, a feeder for applying a breaker and a feeder for applying a tread.

In this device, the rotor is horizontal in the plane and different layers of the breaker are applied from one feeder; therefore, the assembly of the multi-layer bracelet on the known device is carried out at several rotor turns, which leads to the low productivity of the assembly process of the multi-layer bracelets.

This disadvantage is partially eliminated in another device for assembling the belt and tread bracelets, which contains a rotating rotor with rotating assembly drums, feeders for applying breaker layers and a syringe machine for applying a tread. The rotor is made rotatable in the horizontal plane, and the feeders for applying layers of the breaker are installed parallel to each other.

When assembling multilayer bracelets, the feeders move along the assembly drum at the position of the overlap of the breaker layers, which limits the performance of the assembly process of the multilayer breaker-tread bracelets.

The aim of the invention is to increase the productivity of the assembly process of multilayer bracelets.

In order to achieve this goal, in the device for assembling the belt and tread bracelets containing a rotating rotor with rotating assembly drums, feeders for applying the breaker layers and a syringe machine for applying the tread, the rotor is rotatable in a vertical plane, and feeders for applying layers of the belt are mounted coaxially to each other.

The device is equipped with a second syringe installed coaxially with the first.

1 is shown schematically. the described device, a view in plan {figure 2 - view a in figure 1; in FIG. 3, view B in FIG.}; in Fig. A, section B-B in Fig. 1.

The device for assembling the belt protector bracelets comprises a vertically rotatable rotor 1 with rotating assembly drums 2 and 3, feeders 4 and 5 for applying layers of the breaker and a syringe machine 6 and 7 for applying the tread. The rotor 1 by means of the horizontal axis 8 is mounted on the bed 9. The feeders 4 and 5 for applying the layers of the breaker are installed coaxially with each other and include carriages 10 with belt rolls and feed carriages I1.

The rotation of the drums 2 and 3 is carried out by means of gears 12, which are attached to the ends of the drums 2 and 3, interacting with the drives 13. The rotation of the rotor 1 is driven. 14. For removal of the assembled core-tread bracelet, a transport mechanism 15 is designed.

The device works as follows,

In the position of the belt breaker, the assembly drum 2 is first superposed with the first layer of the belt 16 by the feeder 4, and then the second layer of the belt 17 by the feeder 5.

If a multi-layer bracelet is assembled, subsequent layers of the belt are similarly applied either with a feeder 4 only, if a three-layer bracelet is assembled, or with both feeders 4 and 5, if a four-layer bracelet is assembled.

At the end of the decoration of the belt bracelet, the rotor 1 is turned by the drive 14 in a vertical plane 180 and turns the drum 2 to the tread position, and the drum 3 to the breaker position, I

In the manufacture of a belt-tread bristle for passenger car tires with a uniform tread composition, the tread is applied by winding a rubber ribbon manufactured by one of the syringe machines 6 or 7.

When making bracelets of large sizes, both matins can work simultaneously. In the event that the protector should have sidewalls and a running part of different rubber, it is applied first by syringe-6, which forms the running part, and then by syringe machine 7, which forms the sidewalls. Simultaneously, the next belt bracelet is assembled on the drum 3.

The assembled belt and tread bracelet is removed by the mechanism 15 and transferred to the suspension 18, on which it is transported to the place of assembly of pokryachek.

Then the cycle of operation is repeated.

The proposed device is simple in construction, has high performance and occupies a small production area.
