Embodiment Construction

[0026] refer to Figure 1 to Figure 6 , shows a packaging machine 1 for producing sealed packages 2 containing pourable food products from packaging material 3 unwound from a reel (not shown) and fed along an advance path P , such as pasteurized or UHT milk, juice, wine, etc. When the packaging material is unwound from the reel it has the shape of a flat sheet 100 .

[0027] The sheet 100 is fed along an advancement path P through a sterilization unit (not shown), which in one embodiment comprises a sterilization bath, by known guide elements, rollers or similar devices (not shown).

[0028] In another embodiment (not shown), the sterilization unit may comprise other sterilization equipment, such as a sterilization equipment for irradiating the packaging material 3 with a low-voltage electron beam.

[0029] The sheet 100 is fed through the chamber 4 along the advancing path P (e.g. figure 1 Indicated by the dotted line in ), sheet 100 is kept in a sterile air environment in...

Abstract

A packaging machine for producing packages (2) from a sheet of packaging material (3), said packaging material (3) comprising a plurality of marks (20) associated with corresponding portions (21) of said packaging material (3), said packaging machine comprising a working unit (30) having a track arrangement (31) and a plurality of transporting elements (32), each transporting element (32) supporting a tool (40) arranged for carrying out a working operation on said packaging material (3), said transporting elements (32) being movable on said track arrangement (31) independently from each other,each of said transporting elements (32) comprising a sensor device (33) arranged for detecting a corresponding mark (20) and generating a signal indicating the position of said mark (20) with respectto said transporting element (32), said packaging machine further comprising a control unit arranged to control the position of said transporting element (32) along said track arrangement (31) on thebasis of said signal; a method for producing packages (2) from a sheet of packaging material (3) is also disclosed.

Description

technical field [0001] The invention relates to a packaging machine for producing packages from sheets of packaging material. The invention also relates to a method for producing a package from a sheet of packaging material. Background technique [0002] It is known that many food products such as fruit juices, pasteurized or UHT (Ultra High Temperature Treated) milk, wine, tomato paste, etc. are sold in packages made of aseptic packaging materials. [0003] A typical example of this type of packaging is the parallelepiped-shaped packaging for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing laminated strip packaging material. [0004] The packaging material has a multi-layer structure comprising essentially: a base layer for stiffness and strength, which may include a layer of fibrous material (eg paper) or a layer of mineral-filled polypropylene material; and two layers covering the base layer. Mult...
