Title (EN) PROCESS FOR OPERATING A MACHINE FOR WRAPPING PRODUCTS WITH A THERMOPLASTIC FILM
(FR) PROCESSUS DE FONCTIONNEMENT D'UNE MACHINE D'ENVELOPPEMENT DE PRODUITS À L'AIDE D'UN FILM THERMOPLASTIQUE
Abstract:
(EN) A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film (5) from a reel, comprising: - a loading station (19) for the products to be packaged; - a hollow mandrel (3) with a relative forming shoulder (4); - a sealing device (6) for forming a seal (SL) of the longitudinal edges of the film (5); - a horizontally mobile pusher (7) for pushing a bundle of products (P) from the loading station (1 ) through the mandrel (3); - a sealing and transversal cutting assembly (8) formed by two vertically mobile elements (108, 208) mounted on a horizontally mobile primary carriage (9) - a conveyor (10) - a secondary carriage (12) carried by the primary carriage (9); comprising the following operating steps: - reducing the transversal section of the mandrel (3) to a diameter smaller than the diameter of the bundle of products (P) - positioning the sealing device (6) in a position for sealing the overlapped longitudinal edges of the film (5) while forming a new tubular film casing; - arranging the elements (108, 208) of the assembly (8) in a closure position on the head portion of the new tubular film casing and on the tail portion of the tubular film casing of a finished package; - and conveying of said new tubular film casing, by the movement of the primary carriage (9) away from the mandrel (3), and repeating the preceding steps, so that the product placed inside the tubular casing by the mandrel (3) is wrapped in a tight adherent manner due to the elastic retraction of the film of tubular casing.
(FR) Processus de travail d'une machine pour envelopper des produits dans des emballages, mis en oeuvre avec un film de matière thermoplastique (5) à partir d'une bobine, comprenant : - un poste de chargement (19) pour les produits à emballer; - un mandrin creux (3) pourvu d'un épaulement de formage relatif (4); - un dispositif d'étanchéité (6) pour former un joint (SL) des bords longitudinaux du film (5); - un poussoir mobile horizontalement (7) pour pousser un paquet de produits (P) depuis le poste de chargement à travers le mandrin (3); - un ensemble de coupe transversale et d'étanchéité (8) formé par deux éléments mobiles verticalement (108, 208) montés sur un chariot primaire mobile horizontalement (9) - un convoyeur (10) - un chariot secondaire (12) porté par le chariot primaire (9); comprenant les étapes de fonctionnement suivantes : -réduction de la section transversale du mandrin (3) à un diamètre inférieur au diamètre du paquet de produits (P) - positionnement du dispositif d'étanchéité (6) dans une position pour sceller les bords longitudinaux chevauchés du film (5) tout en formant un nouveau corps de film tubulaire; - agencement des éléments (108, 208) de l'ensemble (8) dans une position de fermeture sur la partie tête du nouveau corps de film tubulaire et sur la partie queue du corps de film tubulaire d'un emballage fini; - et transport dudit nouveau corps de film tubulaire, par le déplacement du chariot primaire (9) loin du mandrin (3), et répétition des étapes précédentes, de telle sorte que le produit placé à l'intérieur du corps tubulaire par le mandrin (3) est enveloppé de manière adhésive étanche en raison de la rétraction élastique du film de corps tubulaire.
