Embodiment Construction

[0024] With reference to Figures 1 to 4, the reference number 1 designates generally a sequencing unit for an opening device 3 which may comprise a known pourable food packaging machine of the type described in the background section (not shown). shown).

[0025] More specifically, the unit 1 operates along the supply path A of the opening device 3 . Path A is traveled by each opening device 3 in the direction shown in FIGS. The unit forms part of the packaging machine, interacts with the opening devices 3, and is located downstream of the unit 1 along the path A, such as a unit for depositing adhesive on the opening devices 3, and for gluing each opening device 3 to Units of corresponding packages (not shown).

[0026] Non-limiting examples of packages produced on packaging machines of the above-mentioned type are the parallelepiped-shaped packages known as "TetraBrik Aseptic" (registered trademark) or the so-called "gable tops" found under the trade name "TetraRex" (regist...

Abstract

A sequencing unit operating along a feed path of a number of opening devices for attachment to respective sealed packages of pourable food products includes a conveyor for conveying the opening devices arranged in at least one line, and a releasable stop mechanism interacting with the opening devices downstream from the conveyor along the path. The stop mechanisms are normally set to a first configuration, in which they arrest the opening devices along the path, and are movable into a second configuration allowing travel of the opening devices. The unit also has a push mechanism traveling at predetermined intervals past the stop mechanism to move the stop mechanism from the first configuration to the second configuration, so that the opening devices are fed in sequence and at a predetermined rate through the stop mechanism.

Description

technical field [0001] The present invention relates to a sequencing unit for an opening device to be bonded to a sealed package of pourable food products. Background technique [0002] It is known that many pourable food products, such as fruit juices, VHT (very high temperature treated) milk, wine, tomato juice, etc., are sold in packages made of aseptic packaging material. [0003] A typical example of such a package is the parallelepiped-shaped package called "Tetra Brik Aseptic" (registered trademark) for liquid or pourable food products, which is made by folding and sealing strips of packaging material in layers. Packaging materials have a multi-layer structure comprising a matrix layer for stiffness and strength comprising layers of fibrous material such as paper or mineral-filled polypropylene material covered on both sides by layers of thermoplastic material such as polypropylene vinyl film. In the case of aseptic packages for long-term storage products, such as V...
