Apparatus for controlling the filling of containers

Claim 2

Apparatus for the simultaneous filling of a flowable medium into a plurality of containers, such as tanks, drums, or packs, comprising a main pipe line, a feed pump in the main pipe line for supplying the medium, a plurality of branch supply lines each having one end coupled to the main pipe line, a plurality of valves, one valve in each of the branch supply lines, a plurality of volume chambers, one volume chamber in each branch supply line, each volume chamber having an impeller arranged in its interior to be rotated by the medium flowing therethrough, a mechanical shaft rigidly interconnecting the impellers of all the volume chambers, a braking device for the mechanical shaft, a system pressure-dependent control device for controlling the braking device, a two-stage, pneumatic control cylinder for controlling the valves, an adjusting device directly connecting the pneumatic control cylinder to the valves, means associated with one of the valves for determining the amount of the medium passing therethrough, and a control element coupled to the lastnamed means and responding to the determined amount of the medium for controlling the control cylinder.

Claim 3

Apparatus for the simultaneous filling of a medium into several containers, such as tanks, drums, or packs, comprising: (a) a main pipe line, (b) a feed pump in the main pipe line for supplying the medium therethrough, (c) at least two branch supply lines each having one end connected to the main pipe line for receipt of the medium therefrom, (d) at least two valves, one valve in each branch supply line, (e) at least two volume chambers, one volume chamber arranged in each branch supply line upstream of the valve, with an impeller with a bearing shaft arranged in the interior of each volume chamber to be rotated by the medium flowing therethrough to the valve, (f) means associated with one of the valves for determining the amount of the medium passing therethrough, (g) a two-stage control cylinder directly connected to said one of the valves, (h) a control element coupled to the last-named means and to the two-stage control cylinder and responding to the determined amount of the medium for controlling the two-stage control cylinder to control said one of the valves, (i) at least one pneumatic two-stage control cylinder, each pneumatic two-stage control cylinder connected to one of the remaining ones of the valves, (j) a plurality of flow recorders, one flow recorder connected to each of the volume chambers, (k) a flow data storage device, (l) means connecting the flow recorder of the volume chamber having the valve controlled by the determining means to the flow data storage device for storage, as a desired value, of the throughflowing medium quantity described by the last-named flow recorder, (m) means connecting the flow data storage device of the other volume chambers for comparison of the desired value with the actual values of the other flow recorders, and (n) means responsive to such comparison for controlling the other values so that on reaching the desired values for the volume chambers, the valves associated therewith are disconnected.

Claim 4

Apparatus for the simultaneous filling of a medium into several containers, such as tanks, drums, or packs, comprising: (a) a main pipe line, (b) a feed pump in the main pipe line for supplying the medium therethrough, (c) at least two branch supply lines each having one end connected to the main pipe line for receipt of the medium therefrom, (d) at least two valves, one valve in each branch supply line, (e) at least two volume chambers, one volume chamber arranged in each branch supply line upstream of the valve, with an impeller with a bearing shaft arranged in the interior of each volume chamber to be rotated by the medium flowing therethrough to the valve, (f) means associated with one of the valves for determining the amount of the medium passing therethrough, (g) a two-stage control cylinder directly connected to said one of the valves, (h) a control element coupled to the last-named means and to the two-stage control cylinder and responding to the determined amount of the medium for controlling the two-stage control cylinder to control said one of the valves, (i) at least one pneumatic two-stage control cylinder, each pneumatic two-stage control cylinder connected to one of the remaining ones of the valves, (j) a plurality of flow recorders, one flow recorder connected to each of the volume chambers, (k) a flow data storage device, (l) means connecting the flow recorder of the volume chamber having the valve controlled by the determining means to the flow data storage device for storage, as a desired value, of the throughflowing medium quantity described by the last-named flow recorder, (m) means connecting the flow data storage device of the other volume chambers for comparison of the desired value with the actual values of the other flow recorders, and (n) means responsive to such comparison for controlling the other values so that on reaching the desired values for the volume chambers, the valves associated therewith are disconnected.

Claim 5

Apparatus according to claim 1 or claim 2 in which the means for determining the amount of the medium comprises a balance.

Claim 6

Apparatus according to claim 1 or claim 2 further comprising a regulatable electric motor for driving the impeller of each volume chamber.

Claim 7

Apparatus according to claim 1 or claim 2 in which each volume chamber and the valve associated therewith is constructed as a standard unit permitting extension of an existing apparatus.

Claim 8

Apparatus according to claim 1 or claim 2 in which the means for determining the amount of the medium comprises a rotary piston meter.
