Method and plant for producing tyres for vehicle wheels

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

• storing, after production, green tyres in one or more storage areas without an assigned pick-up logic associated with a respective green tyre, said green tyres have specifications Spj and, for each specification Spj, subspecifications Suh, with 1≤j≤n, 1≤h≤m, and n, and m are integers greater than or equal to 1;
• associating each vulcanizer from a plurality of vulcanizers of a production plant with a respective pick-up logic of different pick-up logics for green tyres from any one of said one or more storage areas of green tyres, 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 production plant during the production of the at least one lot of tyres;
• upon each vulcanization request, applying the pick-up logic associated with a vulcanizer of the plurality of vulcanizers to select and pick up a green tyre from any one of said one or more storage areas;
• and
• transferring the green tyre thus selected and picked up to said vulcanizer,
• wherein:
• the respective pick-up logic associated with each vulcanizer comprises a first pick-up rule of green tyres from any one 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, and, for at least one of said vulcanizers, based on an input received via a user interface, said first pick-up rule is changed into the at least one second pick-up rule at least once during the production, in said plant, of the tyres while said first pick-up rule is maintained for at least one other of said vulcanizers, and further wherein, for the at least one of said 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 said plurality of vulcanizers is configured to vulcanize a green tyre associated with a predetermined specification of said 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 said 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.
