  • Patent number: 6397905
    Abstract: An apparatus for metering and dispensing a liquid into packaging containers (10) has a dispenser device (22) with dispenser heads (23), which communicate via a distributor (30) with a supply container (35). A pressure sensor (32), which ascertains a pressure (P1) prevailing in the liquid, is disposed in the distributor (30). A temperature sensor (27) for detecting the temperature (T) of the liquid is also disposed in at least one line (26) that connects the distributor (30) to a metering valve (25). The sensors (27, 32), communicating with a control device (19), together with weighing devices (17,18) that also communicate with the control device (19), enable exact regulation of the weight of a set-point fill quantity (M) in packaging containers (10). By means of the special disposition of the sensors (27, 32), exact metering of the set-point fill quantity (M) and easy replacement of the supply container (35) are made possible.

  • Patent number: 5823234
    Abstract: A filling machine for filling liquid into containers (10) has a filling valve (25) for each container (10), which valve is actuated by a control device (19) by means of a trigger pulse (Z). In order to increase the precision of the liquid quantity (M (is)) filled into the containers (10) with regard to a desired fill quantity (M), it is proposed that the control device (19) adds up partial volumes (.DELTA.M), which are produced as a function of liquid pressures (P1) measured, the time intervals (.DELTA.t) between the individual pressure measurements, and a pressure/through flow characteristic curve of the filling valves (25). As soon as the sum of the partial volumes (.DELTA.M) has exceeded a limit fill quantity (M (max)), the control device (19) stops the trigger signal (Z).
