Today, two synchronously driven and parallel drylin® ZLW toothed belt axes
are used in the AGV, which pull the container stacks on a wheeled carriage into the transport vehicle. For this purpose, toothed belt axes with stepper motors were necessary, which can pull containers weighing 120 kg. This complete system is very light, requires only low power to operate and is resistant to shock and dirt.
For the movement of the toothed belt axes, the cables are guided by means of an E6 e-chain®
. Their service life is increased and they are protected from external influences. When the containers are completely retracted into the AGV, a barrier closes via an igus® stepper motor to provide additional safety during transport.
For the opening and closing of the robot gripper shafts are supported by igubal® ESTM pillow block bearings. They withstand high radial loads, are self-lubricating and maintenance-free. In order to guide the cables safely during the fast movements of the robot and to ensure long-lasting cables, an E4 series energy chain
is used. In addition, igus® stepper motors
with gearboxes are used so that the gripper can move the containers onto the conveyor belt.
In the meantime, the drylin® R quad blocks with solid plastic bearings and the E4 e-chains® have been in continuous operation successfully for ten years now - without any maintenance or cleaning being necessary.
