Embodiment Construction

[0051] The best way to practice the invention

[0052] figure 1 The number 1 in represents the folding device of the packaging machine as a whole, which is used to continuously produce the sealed parallelepiped package 2 ( Figure 14 ), the package 2 is used to pour food such as pasteurized or UHT milk, fruit juice, wine, etc. from a known tube (not shown) of packaging material.

[0053] More precisely, the tube is formed in a known manner upstream of the folding device 1 by folding and sealing a roll of heat-sealed sheet material in the longitudinal direction and is filled with sterilized or aseptically treated food products.

[0054] The tube of packaging material is then filled with food for packaging, sealed and cut along equally spaced cross-sections to form a number of pillow-like packages 3( Figure 9 ), the pillow packs 3 are then conveyed to the folding device 1 where they are mechanically folded into the corresponding packs 2 .

[0055] see Figure 9 , each packa...

Abstract

A folding device (1) for a packaging machine for packaging pourable food, said folding device (1) having: a transport mechanism (40) for transporting along The forming route (B) feeds at least one sealed package (3) containing a pourable food product and having portions (6, 7) to be folded in order to form a finished package ( 2); and a first folding mechanism (50; 65) having at least one first interaction member (51; 66; 67), the first interaction member (51; 66 ; 67) is movable between a working position and a rest position in which the interacting member (51; 66; 67) cooperates with the package (3) along the path (B) so that the package (3) ) to perform the first forming operation, while in the rest position the interacting member (51; 66; 67) is detached from the package (3); the first interacting member (51; 66; 67) may be A station (B3; B5) moving along a first trajectory intersecting the route (B), where a first forming operation is performed; a first folding mechanism (50; 65), the first folding mechanism (50; 65 ) has at least one first control member (52; 68) and a first transmission (53; 70), the first control member (52; 68) rotates around a first axis (D; F), and the first transmission The means (53; 70) are functionally connected to the first control member (52; 68) and the first interacting member (51; 66; 67); Unidirectional rotation of the control member (52; 68) becomes a back and forth movement of the first interacting member (51; 66; 67) between the working position and the rest position.

Description

technical field [0001] The invention relates to a folding device for producing sealed packages of pourable food products from tubes of packaging material. [0002] It should be noted that in the following description and claims, the term "package" is used in its broadest sense to denote any type of container for packaging liquid and pourable food products, and thus includes not only Manufactured packages and the like, but also bottles, cans, etc. of glass or plastics. Background technique [0003] As is well known, many pourable food products such as juices, UHT (Ultra High Temperature Treated) milk, wine, ketchup, etc. are sold in packages made of sterilized packaging materials. [0004] A typical example of this type of packaging is the parallelepiped-shaped packaging for liquid or pourable food products commonly known as Tetra Brik Aseptic (registered trademark), which is produced by folding and sealing laminated strip packaging material. The packaging material has a mu...
