DESCRIPTION:
BRIEF SUMMARY
FIELD OF USE
The plant according to the invention can be used wherever liquid, gaseous or solid flowable media are to be simultaneously filled into several containers.
PRIOR ART
Filling systems are known for filling liquid, gaseous or flowable products, which are constructed in such a way that even in the case of the simultaneous filling of several containers the in each case necessary quantity of material to be filled is individually fixed. Such a filling system requires a number of devices corresponding to the number of individual filling devices enabling the filling volume or weight of each container to be measured and monitored.
U.S. Pat. No. 3,548,891 discloses a plant for the simultaneous filling of several containers, but using a number of dosing and filling devices corresponding to the number of containers to be filled, an individual filling device being associated with each container to be filled. The filling connections of the filling device permits the filling of individual containers in accordance with the filling volume. However, this plant does not provide for the measurement and monitoring of the filling volume or weight of only a single container, the filling of the other containers being controlled on the basis of the monitoring of said one container.
U.S. Pat. No. 3,205,920 has a filling apparatus with an association of a volume chamber and the coupling of valve actuation.
In the filling apparatus according to Swiss Pat. No. 174,324 a weight-dependent control member is provided, which functions in such a way that the further supply of medium to be filled is interrupted when the in each case given weight is reached. On reaching the desired weight, the further supply of filling medium is stopped. This filling apparatus does not provide for the control of a plurality of filling valves via a single weight-controlled device.
PROBLEM, SOLUTION, ADVANTAGES
The present invention is intended to provide an economic filling system enabling the simultaneous filling of several containers, it being necessary only to measure and monitor the filling volume or weight of one container, which leads to a simple economic filling system, whose operating efficiency can be increased in the simplest possible way at any time and without significant technical expenditure and in which by switching in or out of a drawing-off line connected to the filling system and leading to a further consuming means, such as a tanker or the like, pressure surges occurring in the supply lines are reduced for preventing incorrect measurement results. In addition, a filling system is to be provided enabling several containers to be simultaneously filled, in which the filling volume or weight of only one container is measured and then need be used for controlling the inflow of further medium, so that by means of comparative measurements of flow rates, it is possible to control the filling volume or weight for the other containers. This leads to a simple, economic filling system with a high operating efficiency and without significant technical expenditure. It is only necessary to compare the flow rates to the individual containers with a stored desired value and which permits the control of the further medium supply quantity. It can be housed in several areas, if the single area available cannot receive the complete apparatus with several filling stations. By switching in or out a drawing-off line connected to the filling system and leading to a further consuming means, such as tankers or the like, pressure surges occurring in the supply lines can be reduced to prevent incorrect measurement results.
According to the invention, this problem is solved by a filling plant, which is constructed in such a way that
(a) each of the supply lines leading to the filling valves contains a volume chamber with a rotor arranged in its inner area and which is rotated by the medium flowing to the particular filling valve,
(b) the rotors of all the volume chambers are rigidly interconnected by means of a mechanical shaft, which is connected by a
