Abstract
A method for packaging articles, wherein a single-line flow (40) of articles (A) at the output of a manufacturing machine (12) is converted into a dual-line flow by rotating the articles (A) so that the articles of each pair of adjacent articles (A) are spaced apart from each other in a transverse direction (Y) orthogonal to the moving direction (X).
Description
- The present invention relates in general to packaging of consumer products.
- The invention was developed in particular in view of packaging sanitary article, in particular absorbent sanitary articles, such as: diapers, training pants, absorbent sanitary products for incontinent adults, sanitary napkins, panty liners, etc.
- In the following, reference will be made to this specific field without however losing generality.
- Sanitary articles are usually packaged in boxes or flexible bags containing a fixed number of articles, usually grouped in one or stacks. The sanitary articles may be packaged individually in envelope-shaped wrappers formed by sheets of paper or plastic material.
- Modern machines for manufacturing sanitary articles have extremely high production speeds, in the order of 800-1200 pieces/1'. At the exit of the manufacturing machines, the sanitary articles are output in a single line.
- In many cases, there is the need to split the single-line flow of sanitary articles exiting a manufacturing machine into two separate flows of articles directed to two packaging machines, for instance when one single packaging machine does not have the capacity to handle the whole flow of articles output by the manufacturing machine or when there is the need to form packages with different formats.
- In the prior art, stationary flow dividers are provided when there is the need to split a single-line flow of articles into a dual-line flow.
- The main problems of the prior art stationary flow dividers are the large footprint and the poor flexibility in case of change of packaging format.
- The object of the present invention is to provide a method and a system for packaging articles which overcomes the problems of the prior art.
- According to the invention, this object is achieved by a method and system for packaging articles having the features of claims 1 and 9.
- The claims form an integral part of the technical disclosure provided here in relation to the invention.
- The present invention will now be described with reference to the attached drawings, provided purely by way of non-limiting example, wherein:

The grippingpads 22 may be provided with holes pneumatically connected to a source of sub-atmospheric pressure to retain the articles A by suction. - The
gripping pads 22 rotate about respective axes oriented radially with respect to the axis ofrotation 20 of thespacing wheel 18 so as to space from each other the articles A of each pair of adjacent articles A in a direction parallel to the axis ofrotation 20 of thespacing wheel 18. - With reference to
figure 2 , in a possible embodiment eachgripping pad 22 is configured to grip a pair of adjacent articles A aligned to each other in the moving direction X. Eachgripping pad 22 rotates 90° about a respective radial axis B, so as to distance the two articles A in a direction Y transverse to the moving direction X. After the 90° rotation of thegripping pads 22, the articles A are arranged in a dual line flow of articles A moving in the direction X. The pair of articles A of the dual line flow are aligned to each other in the transverse direction Y. - With reference to
figure 3 , in a possible embodiment eachgripping pad 22 is configured to grip a single article A. Thegripping pads 22 adjacent to each other rotate 180° in the same direction about respective radial axes placed on opposite sides of a central plane, so as to distance each pair of adjacent articles A in a direction Y transverse to the moving direction X. After the 180° rotation of thegripping pads 22, the articles A are arranged in a dual line flow moving in the direction X. The pair of articles A of the dual line flow may be aligned to each other in the transverse direction Y. - The
apparatus 10 may comprise atransfer wheel 24 configured for taking the articles A from thefirst conveyor 16 and for transferring the articles A to thespacing wheel 18. Thespacing wheel 18 receives the articles A from thetransfer wheel 24 in a single-line flow. - The
