  • Patent number: 5740843
    Abstract: A device for filling containers contains a transfer mechanism drivable by a servodrive and which cyclically moves the containers initially to a filling station and then to a balance. By reverse rotation and optionally subsequent forward rotation of the servodrive by a small angle of e.g. 1.degree., it is possible to disengage the transfer mechanism from the containers, so that the latter can be weighed on the balance, without the measured result being falsified by friction between the transfer mechanism and the containers.By multiple rotating backwards and forwards the servodrive by a small angle, it is possible to vibrate the container, so that bridges and the like forming in the material to be filled can be eliminated.
