Area monitoring on a robot
Requirement
For security reasons, the maximum permissible angles of rotation on the different axes of an industrial robot are monitored. So far, roller level switches have been used in conjunction with switching cams. Disadvantage: The mechanics are subject to wear and often have to be readjusted in a complicated way. The task was a low-cost retrofitting to electronic sensors, possibly as a complete set in modular design.
Implementation
Fail-safe inductive sensors of the types GG505S and GG507S were used, connected to the existing PILZ controller. Position detection of the switching cams is carried out without contact. One sensor replaces two roller lever switches. A total of four axes is monitored in this way.
Customer benefits
The solution has proved its worth: Due to the elimination of mechanical components the position detection is now wear-free. Readjustment is no longer necessary, which leads to an increase in plant uptime. Retrofitting with the sets was quick and easy. The solution can be flexibly extended as the application changes.
