摘要：
A device for filling bags with a flowable material has a hopper with a bottom portion for receiving the flowable material. A filling socket is connected to the bottom portion of the hopper and has a vertically downwardly extending receiving section for receiving a bag to be filled. A worm conveyor is horizontally mounted within the bottom portion of the hopper and connected to the filling socket for conveying the flowable material from the hopper to the filling socket. An electric motor is drivingly connected to the worm conveyor. A switch positioned in the vicinity of the receiving section is activated upon slipping a bag to be filled over the receiving section to start the electric motor for the worm conveyor and the switch is deactivated upon removal of the bag after filling to stop the electric motor.
