Abstract

L'invention concerne un procédé pour optimiser le transport d'une bande (2) de matériau d'emballage dans la zone d'un dispositif (20) de mise en forme tubulaire d'une ensacheuse verticale (10), comprenant un dispositif d'alimentation (23a) pour amener une bande (2) de matériau d'emballage plate, thermo-soudable et apte au soudage ultrasonique (2) jusqu'au dispositif de mise en forme tubulaire (20), et un dispositif d'extraction (30) conçu pour retirer une gaine (4) formée avec la bande (2) de matériau d'emballage traversant le dispositif de mise en forme tubulaire (20). Au moins un dispositif (25) de détection pour détecter au moins le glissement (S) et la poursuite d'avancement (N) de la bande (2) de matériau d'emballage ou de la gaine (4) de matériau d'emballage est disposé dans le domaine situé entre le dispositif (23a) d'alimentation en bande et le dispositif (20) de mise en forme tubulaire. Une unité (110) d'entrée du dispositif (100) de commande de l'ensacheuse verticale (10) reçoit, comme valeurs d'entrée, des informations sur les emballages (1) en sachets tubulaires produits à partir de la gaine (4) de matériau d'emballage. Le dispositif (100) de commande lance un processus de calibrage, selon lequel un certain nombre d'emballages (1) en sachets tubulaires sont produits pendant ce processus de calibrage à l'appui des valeurs d'entrée et sur la base des valeurs d'entrée de paramètres machine enregistrés. Pendant la fabrication des emballages (1) en sachets tubulaires lors du processus de calibrage, les valeurs de glissement (S) et de poursuite d'avancement (N) de la bande (2) de matériau d'emballage, valeurs détectées par ladite au moins une unité de détection (25), sont introduites dans le dispositif de commande (100) comme valeurs d'entrée. Et les paramètres machine sont éventuellement adaptés en fonction des valeurs de mesure détectées.
