Publication number: 20190375530Abstract: The horizontal-type automatic packaging machine comprises a conveyor moving a plurality of gripper-holding carriages (4) in an advancing direction (D) along a closed path. Each gripper-holding carriage (4) comprises a base structure (7) connected to the conveyor (2) and two parallel gripper arms (8a, 8b) carrying two or more pairs of grippers (47a, 47b) for holding two or more flexible packages (50) arranged in parallel. The gripper arms (8a, 8b) are guided for moving parallel to the advancing direction (D), moving one closer to the other for opening the packages and moving one away from the other for closing the packages due to the action of a driving mechanism connected to proximal ends (17a, 17b) of the gripper arms. A mechanical transmission transmits the movement of the proximal ends (17a, 17b) to distal ends (18a, 18b) of the gripper arms (8a, 8b).Type: ApplicationFiled: September 27, 2017Publication date: December 12, 2019Applicant: MESPACK, SLInventors: Francisco Mora Flores, Josep Sola Gil
