Abstract
Filling apparatus (10) and method for automatically filling containers (100) for smoking articles with a desired metered quantity of incoherent material (M) of the fibrous type. The apparatus (10) comprises a first and a second filling station (A2, A4) each having one or more delivery devices (22) and being configured to deliver respectively a first and a second quantity of incoherent material (M) into each container (100), wherein the second filling station (A4) is disposed downstream of said first filling station (A2) along a working line.
Claims15
Filling apparatus for filling containers with a desired metered quantity of an incoherent material of a fibrous type, comprising a first filling station comprising a first filling assembly, having one or more delivery devices which are configured to deliver a first quantity of incoherent material into each of said containers, wherein said apparatus is wherein it also comprises at least a second filling station disposed downstream of said first filling station along a working line and comprising a second filling assembly having additional one or more delivery devices, which are configured to deliver a second quantity of said incoherent material into each of said containers, into which said first quantity of incoherent material has already been delivered in said first filling station, and in that it also comprises pressing means disposed downstream of said first filling station and configured to be selectively inserted inside said containers after said first quantity of incoherent material has been delivered, in order to press it before delivering said second quantity of incoherent material in said second filling station.
Filling method for automatically filling containers with a desired metered quantity of an incoherent material of the fibrous type, comprising a delivery step in which one or more delivery devices deliver into each of said containers a determinate quantity of said incoherent material which is a fraction of said desired metered quantity, wherein said delivery step comprises a first sub-step of filling said containers with a first quantity of said incoherent material, carried out in a first filling station comprising a first filling assembly which comprises at least one of said delivery devices, said method being wherein it comprises at least a second sub-step of filling said containers with a second quantity of said incoherent material, carried out in a second filling station disposed downstream of said first filling station along a working line and comprising a second filling assembly having additional one or more delivery devices which are configured to deliver a second quantity of said incoherent material into each of said containers, in which said first quantity of incoherent material has already been delivered in said first filling sub-step, and in that it also comprises a pressing step, subsequent to said first filling sub-step, carried out by means of pressing means disposed downstream of said first filling station, in which said pressing means are selectively inserted inside said containers already at least partly filled with said incoherent material in order to press the incoherent material.
