Drive device of a packaging machine

摘要

A packaging machine comprises a device (13) for forming incomplete containers by forming a web into a tube, filling contents into the tube, thereafter transporting the tube by a length corresponding to one container at a time, and sealing and cutting the tube transversely thereof every time the tube is transported; a container conveyor (14) for receiving the incomplete containers from the device and transporting the containers; and a complete container forming device (15) for making each incomplete container into a complete rectangular parallelepipedal container during transport on the conveyor. A drive device (18) for use in the machine comprises a main shaft (17) coupled to the incomplete container forming device so as to transmit power thereto, and a transmission shaft (183) having one end connected to the main shaft by a main clutch (182) and the other end coupled to a motor (185) by a secondary clutch (184), the transmission shaft being coupled to the conveyor so as to transmit power <IMAGE>
