Roll film palletizing manipulators have evolved from simple “pick-and-place” arms into highly intelligent, “zero-touch” systems. These machines are critical in industries like flexible packaging, lithium-ion battery manufacturing, and food processing, where film rolls (reels) can weigh anywhere from 15kg to 600kg.
The “End-of-Arm Tooling” (EoAT) is the most critical component, as film surfaces are easily damaged by pressure or friction.
Inner Core Expanding Mandrels: The gold standard for heavy rolls. A probe inserts into the roll’s cardboard or plastic core and expands pneumatically to lock it from the inside. This prevents any contact with the film material itself.
Carbon Fiber Vacuum Grippers: In 2026, ultra-lightweight carbon fiber frames (like the COVAL CVGC series) are used to maintain high speeds on collaborative robots (cobots). They use multi-chamber vacuum zones to handle rolls of varying widths without changing tools.
90° Flip-to-Pallet Manipulators: Most manipulators now feature a powered tilt axis. This allows the robot to pick a roll horizontally from a winding machine and “flip” it 90° to stack it vertically on a pallet (or vice versa).
Soft-Touch Adaptive Claws: For smaller, delicate rolls, new Mimosa-inspired soft actuators use FDA-compliant silicone to gently “wrap” around the roll, distributing pressure evenly to avoid “telescoping” the film.
