Method and plant for producing tyres for vehicle wheels

A plant for producing at least one lot of tyres for vehicle wheels comprising:

• at least one building line of green tyres, wherein the green tyres having specifications Spj and, for each specification Spj, subspecifications Suh, with 1≤j≤n, 1≤h≤m, wherein n and m are integers greater than or equal to 1;
• one or more storage areas adapted to store the green tyres built in the at least one building line and without an assigned pick-up logic associated with a respective green tyre;
• a plurality of vulcanizers;
• at least one transfer device adapted to transfer the green tyres from the one or more storage areas to the plurality of vulcanizers;
• and
• a processing unit adapted to, upon receiving a request to vulcanize the respective green tyre, associate each vulcanizer with the respective pick-up logic of green tyres of different pick-up logics for green tyres from any one of the one or more storage areas, wherein the respective pick-up logic is different for at least two vulcanizers of the plurality of vulcanizers and the respective pick-up logic once assigned with each vulcanizer is configured to be changed as a function of requirements of the plant during production of the at least one lot of tyres,
• wherein the respective pick-up logic associated with each vulcanizer comprises a first pick-up rule of green tyres from any of the one or more storage areas, each vulcanizer is configured for the first pick-up rule and at least one second pick-up rule, the respective pick-up logic for each vulcanizer is configured to change during the production as a function of requirements of the plant during the production of the at least one lot of tyres, and, for at least one of the vulcanizers, based on an input received via a user interface, the first pick-up rule is changed into the at least one second pick-up rule at least once during the production, in the plant, of the tyres while the first pick-up rule is maintained for at least one other of the vulcanizers, and further wherein, for the at least one of the vulcanizers, the at least one second pick-up rule is changed into a third pick-up rule during the production, and the third pick-up rule is different from the first pick-up rule and the at least one second pick-up rule,
• wherein each vulcanizer of the plurality of vulcanizers is configured to vulcanize a green tyre associated with a predetermined specification of the specifications Spj,
• wherein the first pick-up rule is different from the at least one second pick-up rule, and the first pick-up rule, the at least one second pick-up rule, and the third pick-up rule are each chosen from:
• First In First Out on the specification Spj for which the respective vulcanizer is configured;
• First In First Out on a predetermined subspecification Suh of the specification Spj for which the respective vulcanizer is configured;
• Last In First Out on the specification Spj for which the respective vulcanizer is configured;
• Last In First Out on a predetermined subspecification Suh of the specification Spj for which the respective vulcanizer is configured;
• punctual selection of a specific green tyre;
• and random selection of a green tyre, and
• wherein each of the one or more storage areas is configured to allow for application of any of the first pick-up rule and the at least one second pick-up rule.
