Abstract
An apparatus for cyclically dosing bulk goods for filling sequentially advanced receptacles has a dosing auger; an electric disc rotor motor connected to the auger to rotate the same and arranged to be electrically braked; a blocking device having an actuated state in which it prevents rotation of the auger and an idle state in which it permits rotation thereof; and a control device for setting the blocking device in the actuated state for blocking rotation of the auger after being brought at least approximately to a standstill by electric braking and thereafter maintaining the blocking device in the actuated state until the beginning of a successive dosing cycle.
Claims4
In an apparatus for cyclically dosing bulk goods for filling receptacles in a filling position into which they are sequentially advanced, including a dosing auger;
- an electric motor connected to the auger to rotate the same;
- braking means for braking the electric motor shortly prior to the termination of a dosing cycle;
- the improvement wherein the electric motor is a disc rotor motor and said braking means is an electric braking means;
- further comprising a blocking device having an actuated state in which it prevents rotation of said auger and an idle state in which it permits rotation of said auger;
- control means for setting said blocking device in the actuated state after said auger has been brought at least approximately to a standstill by said electric braking means and maintaining said blocking device in the actuated state until the beginning of a successive dosing cycle;
- and a sensor means associated with the filling position and connected with an input of said control means for applying a signal thereto in response to sensing the arrival of a receptacle in the filling position;
- said control means including means for energizing said disc rotor motor for starting a dosing cycle in response to the receipt of said signal, means for energizing said electric braking means shortly before termination of the dosing cycle and means for setting said blocking device in said actuated state subsequent to the energization of said electric braking means.
