Abstract
A bag filling and packaging system including gripper pairs around a rotating table so that the grippers of each gripper pair grip two side edges of a bag on which various packaging processes are performed. A gripper distance adjustment auxiliary cam is provided to ascend and descend relative to a gripper distance setting cam for setting distance between grippers. A roller rolls on the two cams as the table rotates, and the distance between the grippers changes in response to the height of the roller by a transmission mechanism. An apparent bag width is measured prior to gripping a bag, the height of the gripper distance adjustment auxiliary cam is controlled according to this measured value, and the distance between grippers in a bag supply process is adjusted accordingly, the amount of part gripped by the grippers at side edges of a bag thus being constant for all bags.
