Filling element, filling system and method for filling containers

Abstract

The invention relates to a filling element (1) for filling containers (4) with a fluid filling material (5), comprising a fluid channel (7) through which the filling material (5) provided in a filling material tank (6) can flow, and which has at least one fluid valve (8) in the fluid channel (7) and discharge opening (9) following the fluid valve (8) in the flow direction of the filling material (5) for discharging the filling material (5) into the respective containers (4) when the fluid valve (8) is open, and comprising a gas channel (10), in particular a flushing and / or pressurising and / or return gas channel, having a gas valve (13) and a gas opening (11) facing the container (4) and / or reaching into an interior (12) of the container (4) during the filling of the container (4). The device (1) is characterised, in particular, in that the gas valve (13) has at least one closed switch status, an open switch status and a partially open switch status. The invention also relates to a filling system (3).

Description

technical field [0001] The invention relates to a filling element for filling containers and a filling system according to the preamble of patent claim 1 or 7 . Furthermore, the invention relates to a method for filling containers according to the preambles of patent claims 8 and 13 . Background technique [0002] Filling elements, filling systems and methods for filling containers according to the generic category are known in various embodiments. For example, in DE 38 07 046 A1 a method for charging a carbonated liquid into a vessel is given. During the filling phase following the pre-pressurization of the vessel, liquid under filling pressure enters the corresponding vessel in a sealed position with the filling element, and the return gas which is forced out by the entering liquid at least temporarily ground from the same vessel via the return gas path of the filling element. [0003] A disadvantage of the known filling elements is that liquid residues often remain stu...

Problems solved by technology

This effect can be compensated by a longer quiet period, however this leads to a corresponding power loss, which is usually undesirable

[0004] A further disadvantage of the known filling systems is that high speeds are inherently desired when filling the container, but this leads to the fact that the exact compliance with the desired filling quantity (or filling height) in the container can only be achieved with further technical effort

[0005] Therefore, despite the existence of solutions known from the prior art, the elimination of the mentioned disadvantages remains a central aim of the further development of filling elements, filling systems and methods for filling containers
