They withstand high radial loads, are self-lubricating and maintenance-free.
When the containers are completely retracted into the AGV, a barrier closes via an igus® stepper motor to provide additional safety during transport.įor the opening and closing of the robot gripper shafts are supported by igubal® ESTM pillow block bearings. Their service life is increased and they are protected from external influences. This complete system is very light, requires only low power to operate and is resistant to shock and dirt.įor the movement of the toothed belt axes, the cables are guided by means of an E6 e-chain® . For this purpose, toothed belt axes with stepper motors were necessary, which can pull containers weighing 120 kg. 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. Soil and moisture contaminate bearing points particularly in this machine. In addition, they had to function without lubrication so that worms and soil remained uncontaminated.
At the other end of the assembly line, a second robot lifts the watered and fed containers off the conveyor belt and onto a trolley, which the AGV picks up and returns to the warehouse.įor the system, Langhoff was looking for components that would function reliably and permanently under difficult operating conditions with dirt, soil and moisture, as the machine was designed for 24-hour continuous operation. The AGV picks up the euro-containers filled with soil and worms in stacks from the warehouse and takes them to the new feeding and watering facility. Arriving at the new feeding and watering facility, the AGV moves the containers to the first robot, which places them one by one from the trolley stack onto a conveyor belt. On the conveyor belt, the containers are then automatically watered and fodder is strewn on the soil. With the system, feeding and irrigation can be carried out around the clock, even when staff are not present.
To fully automate the feeding and watering process, Martin Langhoff, owner of Superwurm, developed a completely new machine. This includes two robots, a conveyor belt and an automated guided vehicle (AGV).
The Langhoff family breeds giant red worms that are used by anglers as feed for the fish.
