Transfer device for transferring empty flexible packages from a package row to two or more package rows applicable to an automatic packaging machine

摘要

The transfer device comprises two grippers (1, 2) supported in respective gripper supports (5, 6) and operated by actuators (3, 4). The gripper supports (5, 6) are movably assembled in a direction (X) parallel to a supply container row (A1) in guide supports (9, 10), which are in turn movably assembled in a direction (Z) in gripper-holding carriages (13, 14), which are in turn movably assembled in a direction (Y) in a base support (50). In the gripper supports (5, 6) cam followers (19, 20) are assembled coupled to guide cams (17, 18) arranged in the corresponding gripper-holding carriages (13, 14). Operating means move the gripper supports (5, 6) and the grippers (1, 2) in combined trajectories in the directions (X,Y, Z).
