Sack gripper keeps a tighter hold than vacuum
TIA's new sack gripper is designed for handling sacks containing materials such as aggregates, grain, sand, potatoes and granules. These types of material tend to be difficult to handle with traditional vacuum grippers, as they are very unstable in the sack and exhibit a fluid-like behaviour that can cause the sacks or bags to sag, so breaking the vacuum hold.
Instead TIA's sack gripper fully encloses the sack and maintains its shape during high-speed handling. The gripper head is available with a matching conveyor section in which the gripper fingers close between the conveyor rollers, allowing them to encompass the sack.
The sack gripper fits most robots and gantries. Pneumatic control is simple and the gripper is fully adjustable, enabling it to handle a wide range of sacks and bags. Various conveyor lengths and sizes are also available. Other options include side and top pressure plates.
Robust construction allows the gripper to be used in dirty or dusty environments, and powder-coated and plated parts prevent corrosion. Stainless steel and other custom versions are also available.
