The robot has a motor-driven gripper equipped with angled edges at the bottom. This increases gripping security and operating speed. The angled edges allow significant reduction of the gripping force so that the sensitive nonwoven products can retain their shape.
The frame used for centering the products on each layer allows the use of a smaller, faster robot. All movements of the robot are carried out at high speeds.
When the robot has formed a layer, the frame is lowered, retaining the entire layer in place.For lightweight disposable hygiene products, Optima Group Nonwovens' RTP25 model's vertically moving frame is particularly suitable, as it firmly holds the compact and stable stack formations in place.
The pre-stretched film used for securing the stack is wrapped by a system that continuously measures applied forces and controls them according to the relevant setting. This is a highly protective approach for the lightweight nonwoven products because the stack is wrapped without being moved on the pallet and it is kept firmly in place.
