Title (EN) PROCESS FOR CONTROLLING THE ADDITION OF WATER IN A RUBBER MIXTURE FOR PRODUCING TIRES
(FR) PROCÉDÉ DE CONTRÔLE DE L'AJOUT D'EAU DANS UN MÉLANGE DE CAOUTCHOUC POUR LA FABRICATION DE PNEUMATIQUES
Abstract:
(EN) A process for controlling the addition of water in a rubber mixture produced during a mixing cycle in which the rubber mixture (108) is transported in the form of a continuous sheet (112) and along at least a portion of which at least one spray system sprays water that is controllably evacuated by at least one aspiration system, characterized in that the process comprises the following steps: obtaining data unique to each rubber mixture that includes at least a predetermined water flow rate delivered by the spraying system, a predetermined air flow rate delivered by the aspiration system and target values of temperature and water content for the rubber mixture; detecting an amount of water added at an elapsed during the mixing cycle; using the detected amount of water to predict values of temperature and water content for the rubber mixture at the end of the mixing cycle in progress; comparing the target values and the predicted values; and between successive mixing cycles, adjusting the actual water flow rate when a comparison indicates non-equivalence.
(FR) L'invention concerne un procédé de contrôle de l'addition d'eau dans un mélange de caoutchouc produit pendant un cycle de mélange, dans lequel le mélange de caoutchouc (108) est transporté sous forme d'une feuille continue (112) et le long d'au moins une partie dont au moins un système de pulvérisation pulvérise de l'eau qui est évacuée de manière régulée par au moins un système d'aspiration. Le procédé comprend les étapes suivantes : obtenir des données propres à chaque mélange de caoutchouc qui comprennent au moins un débit d'eau prédéterminé fourni par le système de pulvérisation, un débit d'air prédéterminé fourni par le système d'aspiration et des valeurs cibles de température et de teneur en eau pour le mélange de caoutchouc ; détecter une quantité d'eau ajoutée durant un laps de temps pendant le cycle de mélange ; utiliser la quantité d'eau détectée afin de prédire des valeurs de température et de teneur en eau pour le mélange de caoutchouc à la fin du cycle de mélange en cours ; comparer les valeurs cibles et les valeurs prédites ; et ajuster, entre des cycles de mélange successifs, le débit d'eau réel lorsqu'une comparaison indique une non-équivalence.
