Counting and triggering

  Micrometer-exact positioning of punching strips.

During the production of punched articles, the punching procedure requires the exact positioning of the punching strips as the processing of the punching strip is performed in a number of process steps in the punching machine. The metal band must be positioned exactly within the punching tool after every processing step (punching and bending procedure). The position notification is usually performed within a stroke procedure (0°…180°) using a through beam light barrier and assignment of the respective rotary encoder position during the signal exchange of the light barrier. Ideally, the through beam light barrier should be a fork light barrier and should be able to be integrated in the punching tool, something which requires robust sensors which can resist mechanical vibration. The light barrier should be cutting oil resistant and insensitive to soiling. Quick running punching machines under the presses running at several thousand strokes per minute require a very high switching frequency and a high degree of position-exactness.
The fork light barriers of the FIA-L series from Sensor Instruments GmbH were designed especially for this deployment. In addition to a high degree of insensitivity to extraneous light, a high level of oil resistance, a small laser spot size of 0.2mm in diameter, a low optical divergence of the red laser beam and a high position exactness of better than 5µm, the FIA-L-RL series provides a switching frequency of 25kHz.
