Benefits of technology

"The invention provides a method and plant for packaging flexible bags in cardboard boxes. The method involves inserting a flexible bag into a cardboard box through a funnel and an insertion tube, which prevents damage to the bag and reduces the risk of tearing the bag's plug and stopper when entering the cardboard box. The plant includes a flexible-bag supply station, a cardboard box supply station, a loading station, and a finishing and / or evacuation station. The invention allows for easier packaging, reduces risks of damage to the bag, and increases productivity compared to traditional linear or sequential rotary box-filling lines."

Problems solved by technology

As a matter of fact, in the case of small-volume flexible bags, the risk of their blocking in the funnel is thus increased, since their weight is not sufficient to force their passing through the latter whose cross-section is reduced.
Anyway, under the action of its dropping and entering into contact with the cardboard box, the flexible bag is subjected to important frictions, which may lead to a local deterioration and, thus, to a risk of leaking.
Furthermore, that risk is very high since, in order to guarantee the insertion in some way of the flexible bag into the cardboard box, it is dropped vertically into the latter.
Therefore, it can be considered that said flexible bag is brutally handled, which results into a non inconsiderable number of defective packages.
To this is to be added the problem related to the risk of tears at one of the walls of the cardboard of the closing, in this case the tap the plug of the flexible bag is generally provided with, during this falling in vertical position.
As the case may be, this not only slows down the progress of the flexible bag, increases the risks of blocking, and creates a risk of leaking, but, in addition, can result into changing its positioning inside the package.

Embodiment Construction

[0042]This invention refers to a method and a plant for packaging flexible bags filled with a liquid or non-liquid, foodstuff or non-foodstuff, sterile or non-sterile product.

[0043]In a preferred embodiment, such a plant is continuously rotating, with cam-control means for the various actuating devices. In another embodiment, the plant can be made linear and continuous.

[0044]Usually, the flexible bags 1 aimed at containing liquid or non-liquid products, namely foodstuff or the like, are made of at least two films of synthetic material or the like, of the single or multiple layer type, superimposed and welded at their periphery so as to define a container.

[0045]At least one of the films is drilled with an opening for receiving a plug 2 receiving a stopper such as a distribution tap or the like.

[0046]A filling unit 3 is specially designed for ensuring the filling of these bags 1, also called wine skins, as the case may be either through the plug 2 or an opening that is subsequently cl...

Abstract

The invention relates to a method for packaging of flexible bags, filled with a liquid or non-liquid, foodstuff or non-foodstuff, sterile or non-sterile product. A packaging box is fitted on an introduction tube, essentially extending the whole height of the box. A flexible bag is dispensed from a supply point for flexible bags into the box through a funnel and the introduction tube, which forms an extension. The packing box, containing the flexible bag for the introduction tube is removed. The plant for the packaging of flexible bags filled with a liquid or non-liquid, foodstuff or non-foodstuff, sterile or non-sterile product, carries out the method.
