A packaging machine includes a compact dynamic shuttle buffer arranged upstream of a packaging station.

Packaging machine with dynamic buffer and its assembly method

A working process of a machine for wrapping products in packages, carried out with a thermoplastic material film from a reel, the process comprising: reducing a transversal section of a hollow mandrel to be smaller than a transversal dimension of a bundle of products, positioning a sealing device in a position for sealing overlapped longitudinal edges of the film while forming a new tubular film casing, arranging two vertically mobile elements of a sealing and transversal cutting assembly 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 the new tubular film casing away from the mandrel, and repeating the process so that the product placed inside the tubular casing by the mandrel is wrapped in a tight adherent manner due to the elastic retraction of the film.

A packaging machine with a carousel with horizontal axes, particularly suitable for packaging rolls of paper or packs of paper serviettes or other solid products of variable size, of the type that comprises a plurality of identical seats on the same carousel, angularly equidistant from each other, radially open towards both the outside and the inside and each formed by a longitudinal wall fastened perpendicularly to said carousel and by a parallel and opposite wall, the distance of which from said fixed longitudinal wall can be adjusted to ensure that, with a movement parallel to the axis of the carousel, a product of variable size with its wrapping sheet can be inserted between these walls, and wherein the same seats comprise, between said longitudinal walls, two transverse walls designed to cooperate with the ends of said product with the wrapping sheet inserted in the same seats, which for this must have an adjustable reciprocal distance, whereby at least one of these transverse walls is connected to means for adjusting the distance from the other transverse wall, characterized in that said adjustment means comprise, for each said wall, respective internal threads and respective slides sliding on respective rectilinear guide means, directly or indirectly supported by the table of the carousel and parallel to the movement of the associated walls, with two sets of screws being provided parallel to these guide means that cooperate with said internal threads, which are also rotationally supported, directly or indirectly, by said table, these screws being kinematically connected to each other by associated means to ensure that by acting on one of the components of these connection means, the adjustment of the dimensions in length and in width of all the seats is performed in a centralized, rapid and precise manner to adapt them to the different sizes of the products to be packaged.
