Abstract

A particle removal device for a filling machine configured to form, fill, and seal individual packages is provided. The particle removal device comprises an air supply pipe, and a controller being programmed to activate the particle removal device such that a jet of air is directed into a ready-to-fill package passing the particle removal device.

First claim

1 . A particle removal device for a filling machine configured to form, fill, and seal individual packages, wherein the particle removal device comprises an air supply pipe,
a controller being programmed to control the particle removal device such that a jet of air is directed into a ready-to-fill package passing the particle removal device.

2 . The particle removal device according to claim 1 , wherein the controller is programmed to control activation of the particle removal device based on the motion of ready-to-fill packages passing the particle removal device.

3 . The particle removal device according to claim 1 , wherein the controller is programmed to control activation of the particle removal device for an entire indexing cycle, during which two consecutive ready-to-fill packages are passing the particle removal device.

4 . The particle removal device according to claim 3 , wherein the jet of air is constant during activation.

5 . The particle removal device according to claim 1 , wherein activation of the particle removal device is started when a leading sidewall of a ready-to-fill package is positioned in the same vertical plane as an orifice of the air supply pipe.

6 . The particle removal device according to claim 1 , further comprising a hood, and wherein the air supply pipe is arranged inside said hood.

7 . The particle removal device according to claim 6 , wherein the hood is provided with an air evacuation unit.

8 . The particle removal device according to claim 6 , wherein an orifice of the air supply pipe is arranged vertically below the bottom end of the hood.

9 . The particle removal device according to claim 1 , wherein the hood is dimensioned to cover at least one ready-to-fill package.

10 . A filling machine, comprising a particle removal device according to claim 1 .

11 . The filling machine according to claim 10 , further comprising a cap applicator station, and wherein the particle removal device is arranged downstream the cap applicator station.

12 . The filling machine according to claim 10 , further comprising a disinfection station, and wherein the particle removal device is arranged upstream the disinfection station.

13 . A method for a filling machine configured to form, fill, and seal individual packages the method comprising:
providing a particle removal device in accordance with claim 1 , and activating said particle removal device such that a jet of air is directed into a ready-to-fill package passing the particle removal device.
