Our customer was reusing a die cut press at a new location. The press runs in a cycle starting in safe position, material is fed in to the press, then the press acts in a clam shell motion closes and then opens ending back in the safe position, then material is removed, and finally the cycle starts again.
The press needs a light safety curtain set up that allows the user to feed material to the press when it is in its safe position. This exposed two issues that RSA’s engineers were able to solve. First the normal vertical set up of the safety curtain lights would interfer with the path of the material. Second, the light curtain needed to be muted while the press was in the safe position so that material could be fed onto the press without needing to reset the machine and maintaining safety protocols.
RSA was brought in to help solve both issues. First we built a C frame to support the light curtain in a horizontal configuration. This configuration meets safety compliance and allows the user to feed the press without hitting the light bars. Second, we installed a safety sensor on the press to indicate when the press is in the safe position. Then we programmed a controller to mute the light curtain when the safety sensor is in the safe position.
We ensured that both of these steps are within safety guidelines. RSA took the time to learn how the existing controller and safety mechanism on the press worked so that we could properly install the new switch and controller. RSA uses our expertise and experience to put the right tools in place resulting in a safe environment that is reliable and economic.
