Body and Chassis Welding Cell
During car manufacturing, automated robot welding cells are used to accurately and efficiently spot weld automobile frames. Multiple robots spot weld on the frames at any given time in each cell.
The Challenge
Personnel may need to gain access to the welding cell for some tasks. In these circumstances, access should only be permitted once machinery has come to a controlled stop. There is also a risk of personnel becoming trapped.
The Solution
amGardpro with proNet
Fortress recommended an amGardpro interlock with guard locking function and proNet option pod (with pushbuttons and emergency stop) that communicates over EtherNet/IP. A request to enter via the pushbuttons sends a signal to the welding cell’s control system, bringing the robot and the conveying system to a controlled stop. Subsequently, the interlock is unlocked and the actuator is released.
A padlockable drop down on the head of the interlock can be used to perform interlock blocking and prevent unexpected start-up. There is also a single handle escape release to allow personnel to escape should they become trapped.
