Process and plant for building tyres for vehicle wheels

Abstract

There is described a plant for building tyres for vehicle wheels, said tyres being of at least two different models, comprising at least a tyre building line (1) which in turn comprises: - a plurality of work stations (4, 4', 5, 5', 6, 12, 14) arranged according to a sequential series, each work station (4, 4', 5, 5', 6, 12, 14) being adapted for building at least one structural component of each tyre, assembling at least one elementary component; - at least one handling device (3) for the tyres being processed on the respective forming supports associated to each work station (4, 4', 5, 5', 6, 12, 14); and - at least one transfer device (2) adapted for transferring the tyre being processed on its forming support from any first work station (4, 4', 5, 5', 6, 12, 14) of said sequential series to any other second work station (4, 4', 5, 5', 6, 12, 14) not adjacent thereto of said sequential series, so that the tyre being processed on its forming support only passes in said first and second work station (4, 4', 5, 5', 6, 12, 14). There are also described a process for manufacturing tyres for vehicle wheels and a method for selecting work stations (4, 4', 5, 5', 6, 12, 14) of a tyre building plant.

Description

technical field [0001] The invention relates to a process for building tires for vehicle wheels. [0002] The invention also relates to a plant for building tires for vehicle wheels, which can be used to carry out the above-mentioned building process. Background technique [0003] The tire production cycle includes a construction process in which the various components of the tire itself are manufactured and / or assembled on one or more construction lines, followed by molding and vulcanization on suitable curing lines for shape and tread pattern to define the tire structure. [0004] Tires generally comprise a toroidal toroidal carcass comprising one or more carcass plies composed of so-called "radial "Reinforcing cords in tires for reinforcement. Each carcass ply has ends integrally connected with at least one metallic reinforcing annular structure, called a bead core, which constitutes a reinforcement at the bead, that is, in the radial direction of the tire end, and ha...

AI Technical Summary

Problems solved by technology

[0019] The method exemplified in EP 1481791 is technically flexible because it allows tires to be obtained from semi-finished products having characteristics different from each other, but the method has certain limitations in terms of productivity, for example when the types of tires to be produced vary and require large equipment to implement these methods when

[0020] Furthermore, the applicant has noticed that, in the production system of the latter type of tire, the management of large quantities of material and / or semi-finished products creates problems in synchronizing the production steps of the various parts that make up the tire, and that the resulting General management issues, which negatively impacted productivity

[0021] Finally, the Applicant has found that, in all the plants exemplified in the above documents, if a single workstation fails, the entire construction plant has to be stopped, which is an obvious disadvantage of this example
