Parts-Out Sensing

Stamping dies continuously eject finished parts onto conveyors or into bins. To avoid damage to the die and to the part, it is critical to verify that parts have been successfully ejected. Balluff Dynamic Optical Windows (BOWA) provide a unique "on the fly", solution for verification of parts ejection from stamping dies - even at high speeds and random orientations and trajectories (both signal duration and sensitivity adjustments are provided on the sensor). Stationary tubes or funnels can be installed within the BOWA for "forced directional aiming" of finished parts. Balluff's "self contained thru beam" BGL sensors offer a unique solution for parts-out verification. Unlike fiber optic sensors that must be used with a separate amplifier, the emitter/receiver of the BGL device is contained in a solid, rigid metal frame that never goes out of alignment. The "forked" design, which comes in 5 to 220 mm widths, straddles the area where finished parts are ejected and verified.
