Device for manufacturing, filling and sealing sacks

摘要

The invention relates to device for manufacturing, filling and sealing thermoplastic sacks that are open on one side. Said device comprises a first welding and severing station for forming the sack with a bottom weld, a filling station and a second welding station for sealing the sack and comprises a first pair of gripping pliers as the pair of transport gripping pliers for accepting the sack at the first welding station; a second pair of gripping pliers that are arranged stationarily at the filling station; and a third pair of gripping pliers as the pair of transport gripping pliers that transport the sack from the filling station to the second welding station. The invention provides a fourth pair of gripping pliers as the pair of transport gripping pliers that accepts the sack from the first pair of transport gripping pliers through the in-line arrangement of a stationary pair of gripping pliers and delivers to the pair of gripping pliers, which are arranged stationarily at the filling station. Said fourth pair of gripping pliers assumes a delivery position to deliver the sack to the pair of gripping pliers that is arranged stationarily at the filling station and that lies in a plane that is higher by a distance (x) than its acceptance position for the sack.
