"PACKAGING PLANT FOR GROUPS OF ABSORBENT HYGIENIC ITEMS AND PROCESS"

FIELD OF APPLICATION

Embodiments of the present invention relate to a plant for packaging groups of absorbent hygienic articles, such as for example diapers, diapers-pants, diapers for incontinence, sanitary napkins, or other articles intended to absorb body fluids.

Embodiments of the present invention also relate to a method for managing a plant for packaging groups of absorbent hygienic articles.

STATE OF THE TECHNIQUE

In the sector of absorbent hygienic articles, the need to create packages with a desired number and / or type of groups of absorbent hygienic articles is known.

These packages are made by packaging machines functionally connected to respective production machines which supply groups of absorbent hygienic articles each with its own production rate.

By virtue of the market requirements and the variety of absorbent sanitary articles available, these groups may comprise an equal or different number of articles and, moreover, they may comprise the same or different sanitary absorbent articles.

For example, a first group of absorbent sanitary articles can comprise two incontinence diapers, five diapers, and thirteen female sanitary napkins, and a second group of absorbent sanitary articles can comprise twenty diapers.

Those skilled in the sector are unable to meet the needs of consumers on a large scale, as efficient methods and apparatuses are not known for producing customized packages comprising groups of absorbent sanitary articles that differ from time to time in relation to the demands of the various consumers.

The solutions known in the field have not yet made it possible to process and package a plurality of combinations of groups of absorbent hygienic articles in a short time.

Some known solutions provide for the packaging of a fixed number of groups of absorbent hygienic articles of the same type.

This makes it possible to only partially satisfy the demands of consumers who do not find customized packages with various groups of hygienic absorbent articles on the market. One of the main problems encountered in known plants is that they comprise different production machines which may have very different production rates.

This did not allow to provide an efficient solution that was able to coordinate the production of articles at different rates with their packaging.

If it is necessary to package groups of absorbent toilet articles with different numbers and / or different types of absorbent toilet articles supplied by different production machines, it is known that these activities are carried out offline, i.e. in a grouping station not connected to the production machines. and to the packaging machines by operators who manually group the absorbent hygienic articles in relation to the specific customized package to be created.

It is known that such solutions that involve the use of operators for manual packaging are slow and, moreover, are subject to multiple errors that cannot be monitored and for which it is not possible to implement actions to prevent them from happening again.

Other known solutions require frequent modifications to the system in order to process and package different combinations of groups of absorbent hygienic items. This significantly increases costs and production times.

If it is intended to make a package comprising various groups of absorbent sanitary articles and an additional article, be it a specific absorbent sanitary article, an advertising leaflet, or another promotional item, the operators must supply these additional articles manually and supply them to the packaging machine, after interrupting the formation of the groups of absorbent hygienic articles coming from the production machines.

This leads to lengthy and expensive downtime to the detriment of the manufacturers of absorbent sanitary ware.

Other solutions provide for producing a plurality of absorbent hygienic articles and storing them in such a way as to be able to package them manually at subsequent times in relation to the customized packages requested by consumers.

These known solutions present considerable problems both from a warehouse point of view and from a point of view of maintaining the performance of the absorbent hygienic articles, since it is known that such absorbent hygienic articles can also remain in the warehouse for long times.

This entails high costs and considerable losses as the articles, deteriorating over time, can no longer be put on the market.

Therefore, there is a need to improve and make available a plant for packaging groups of absorbent hygienic articles, as well as a method for managing a plant for packaging groups of absorbent hygienic articles that overcome at least one of the drawbacks of the known art.

An object of the present invention is to provide a plant for packaging groups of absorbent toilet articles which is flexible and which allows to process various and different groups of absorbent toilet articles in a short time in relation to the specific batches to be packaged. It is also an object of the present invention to provide a plant for packaging groups of absorbent hygienic articles that does not require modifications to the plant itself, or the use of operators, to package groups of absorbent hygienic articles comprising different articles and / or groups with different numbers of sanitary napkins.

A further object of the present invention is to provide a method for managing a packaging plant that allows the plant itself to be managed efficiently so as to obtain various customized packages in a short time, without the need to interrupt production, and without the use of operators for manual packaging.

In order to obviate the drawbacks of the known art and to obtain these and further objects and advantages, the Applicant has studied, tested and implemented the present invention.
