Abstract

A filling system has a filling apparatus ( 200 ) and a container arrangement inserted into the filling apparatus. A main line includes a feed line ( 102 ), connected to a supply container ( 304 ), and a trunk line ( 104 ), connected linearly downstream of the feed line ( 102 ). Outside the trunk line ( 104 ), at a branching point ( 114 ), a branch line ( 116 ) branches from the main line ( 102 ) to a compressed-gas source ( 306 ), and the main line ( 102 ) and the branch line ( 116 ), on that side of the branching point ( 114 ) which is directed away from the trunk line, pass through a double-valve arrangement ( 214 ) having two hose-clamping valves ( 214 a, 214 b ) controlled oppositely to one another.

First claim

The invention claimed is:

1. A filling system comprising a filling apparatus and a container arrangement arranged in the filling apparatus, wherein the container arrangement comprises:
a main line which comprises a feed line connected to a supply reservoir and a pump, and a trunk line connected in linearly downstream of the feed line, and
a plurality of target containers, which are each connected to the trunk line via a connecting line,

and wherein the filling apparatus comprises:
a support framework configured to mount the target containers,
a valve support comprising a plurality of target container valves corresponding respectively to the plurality of target containers and with which a volume flow through respective ones of the connecting lines is controlled,

wherein at a branching point in a region of the feed line, a branch line branches from the feed line, and the feed line and the branch line on a side of the branching point facing away from the trunk line extend through a double valve arrangement, having two pinch valves which are configured to be controlled contrary to one another, the feed line being connected into one pinch valve and the branch line being connected into the other pinch valve, and
wherein the branching point is arranged on a side of the pump toward the trunk line and the branch line extends to a pressurized gas source.

2. The filling system as claimed in claim 1 ,
wherein
a gas-permeable sterile filter is integrated into the branch line.

3. The filling system as claimed in claim 1 ,
wherein
the main line further comprises a tapping-off line which is connected linearly downstream of the trunk line.

4. The filling system as claimed in claim 3 ,
wherein
the valve support further comprises a discharge valve configured to control a volume flow between the trunk line and the tapping-off line.

5. A filling method using a filling system as claimed in claim 3 , comprising filling, through coordinated control of the valves of the valve support, at least one target container with fluid from the supply reservoir such that at least one residue container remains unfilled,
passing residual fluid remaining in the main line to the residue container, opening the target container valve associated with the residue container, closing the trunk line at the end thereof facing away from the branching point, closing the feed line with the pinch valve of the double valve arrangement associated with the feed line, and opening the branch line with the pinch valve of the double valve arrangement associated with the branch line, such that pressurized gas from the pressurized gas source forces the residual fluid into the residue container.

6. The method as claimed in claim 5 ,
wherein
the residue container is connected to the trunk line via the connecting line that is arranged linearly most distant from the branch point.

7. The filling system as claimed in claim 1 ,
wherein
the valve support further comprises a main valve configured to control a volume flow from the feed line to the trunk line.
