Abstract

An apparatus for forming a collation of rod-shaped aerosol-generating articles is provided, including: multiple movable pockets, each pocket to house a collation having a number of layers of the articles; a number of hoppers forming a reservoir of the articles, each hopper to provide a respective transfer set of the articles to the collation; and a control system to control relative movement of the respective pocket with respect to the hoppers, the respective pocket to be arranged next to each hopper enabling transfer of the respective transfer set of the articles from the respective hopper to the respective pocket, a cumulative number of the articles in all transfer sets is greater than a number of the articles in the respective collation, and the control system is further to vertically move the pockets independently of each other relative to the hoppers and/or to move the hoppers independently of each other.

First claim

The invention claimed is:

1 . An apparatus for forming a collation of rod-shaped aerosol-generating articles, the apparatus comprising:
multiple movable pockets, each pocket being configured to house a collation having a number of layers of the rod-shaped aerosol-generating articles; a number of hoppers forming a reservoir of the rod-shaped aerosol-generating articles, wherein each hopper is configured to provide a respective transfer set of the rod-shaped aerosol-generating articles to the collation; and a control system configured to control relative movement of the respective pocket with respect to the hoppers, wherein the respective pocket is configured to be arranged next to each hopper enabling transfer of the respective transfer set of the rod-shaped aerosol-generating articles from the respective hopper to the respective pocket, wherein a cumulative number of the rod-shaped aerosol-generating articles in all transfer sets is greater than a number of the rod-shaped aerosol-generating articles in the respective collation, and wherein the control system is further configured to vertically move the pockets independently of each other relative to the hoppers and/or is further configured to move the hoppers independently of each other.

2 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , wherein the number of hoppers is greater than the number of layers in the collation.

3 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , wherein when the control system detects a fault condition in one of the hoppers, the control system excludes this hopper from transferring the rod-shaped aerosol-generating articles from this hopper to the pockets.

4 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 ,
wherein at least one hopper of the number of hoppers and the pockets are configured to enable relative movement between at least a part of the hopper and the pockets, and wherein the movement is orthogonal to an extension of the layers of the collation.

5 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , wherein at least a part of one or more hoppers of the number of hoppers is movable in a direction substantially orthogonal to an extension of the layers of the collation.

6 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , wherein each hopper comprises an inserter assembly for pushing one or more rod-shaped aerosol-generating articles from the hopper into the pockets.

7 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 ,
further comprising a transport system with a track, wherein the pockets are configured to move along the track.

8 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 7 , wherein the multiple pockets are movable independently of each other along the track.

9 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 7 ,
wherein one or more pockets are removably arranged on a carrier, and wherein the carrier is arranged on and movable along the track.

10 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , wherein at least two pockets have an inner shape different from each other, suitable to receive a collation of a different format.

11 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , further comprising a packer unit configured to form a package around the collation of rod-shaped aerosol-generating articles.

12 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , further comprising an inspection system configured to detect a defective collation or rod-shaped aerosol-generating article in a pocket.

13 . The apparatus for forming a collation of rod-shaped aerosol-generating articles according to claim 1 , further comprising an identification device configured to identify the pockets based on an identifier on the pockets.

14 . A method for forming a collation of rod-shaped aerosol-generating articles, the method comprising the steps of:
providing multiple pockets and a feeder unit comprising a set of hoppers; and performing a number of transfer steps to form the collation in a pocket of the multiple pockets, wherein each transfer step of the number of transfer steps comprises arranging the pocket next to a hopper of the set of hoppers and transferring at least one rod-shaped aerosol-generating article from the hopper to the pocket, wherein a number of hoppers in the set of hoppers is greater than the number of transfer steps, and wherein a control system is configured to vertically move the pockets independently of each other relative to the hoppers and/or is configured to move the hoppers independently of each other.

15 . The method for forming a collation of rod-shaped aerosol-generating articles according to claim 14 , wherein said each transfer step of the number of transfer steps is performed with a different hopper of the set of hoppers.

16 . A method for forming a collation of rod-shaped aerosol-generating articles, the method comprising the steps of:
arranging a first pocket subsequently next to a first set of hoppers; transferring at least one rod-shaped aerosol-generating article from each hopper of the first set of hoppers to the first pocket to form a first collation; arranging a second pocket subsequently next to a second set of hoppers; and transferring the at least one rod-shaped aerosol-generating article from said each hopper of the second set of hoppers to the second pocket to form a second collation, wherein the second set of hoppers comprises at least one hopper that is not comprised in the first set of hoppers, and wherein the first set of hoppers and the second set of hoppers share one, two, or three common hoppers.

17 . The method according to claim 16 , wherein the first set of hoppers comprises at least two hoppers and the second set of hoppers comprises at least two hoppers.
