Abstract
The invention relates to a filling device for filling bags with a respective unsealed upper end and at least two layers lying on top of one another. A filling station for filling the bags in characterised in that the filling device comprises at least one layer movement device (30) for moving the at least one layer of the bag relative to the at least one second layer, with which the layers of the bag can be acted upon, wherein the layer movement device is arranged in front of the filling station.
Claims18
A filling device for filling bags with a respective unsealed upper end and at least two layers lying on top of one another, the filling device comprising:
- a filling station for filling the bags, wherein the filling station comprises suction cups for opening the bag,
- at least one layer-moving device for moving said at least one layer of the bag in relation to said at least one second layer, with which it is possible to have an impact upon the layers of the bag, wherein the layer-moving device is arranged in front of the filling station,
- wherein the layer-moving device comprises at least one suction device, which engages with the outside of a layer of the bag,
- a transport device configured to transport the bag from the layer-moving device to the filling station such that the layers of the bag lie on top of one another, the interior of the bag is free of tools while the bag is being transported, and no fluid or ambient air gets into the interior of the bag, and
- at least one retaining device with which the bag can be held in the at least one layer-moving device, wherein the retaining device holds the layers of the bag in such a way that they are compressed.
A method for filling bags with one respective unsealed upper end and at least two superimposed layers, wherein the filling is done at a filling station comprising suction cups for opening the bag, the method comprising:
- exerting an impact upon at least one layer of the bag, using at least one layer-moving device, in order to move said layer in relation to said at least one second layer, wherein the layer-moving device is placed in front of the filling station and the layer-moving device comprises at least one suction device, which engages with the outside of a layer of the bag;
- transporting the bag from the layer-moving device to the filling station such that the interior of the bag is free of tools while the bag is being transported and no fluid or ambient air gets into the interior of the bag;
- and
- holding the layers of the bag in such a way that they are compressed.
