The importance of flexibility in production systems is growing rapidly.
Traditional installations often have predetermined dimensions of the workstations. Because of sometimes larger products, people choose for the certainty of a larger installation at the expense of profitability.
An important part of the mandatory safety is the zone protection of a robot installation. This protection ensures that a fixed size of each workstation has to be chosen. Converting a workstation is cumbersome and usually unprofitable. That is why Valk Welding was looking for a solution in which the zone strips can move flexibly along with the movable fence.
The idea of the unique "Valk Welding Only" system is in a guided chain system where the chain forms a closed loop. At the height of the fence between the two stations, the chain is connected in a staggered way and this jump is recognised by the zone protection as the transition from one zone to the other.
The system is possible for robotic systems with 2 workstations on one side of the robot track.
