ABSTRACT:
An apparatus for eliminating excessively thick elongated articles medially positioned on and advanced by a first conveyor in an orientation transverse to the direction of advance, comprises a sensor arranged above the first conveyor and responding to an article having a thickness exceeding a predetermined magnitude; and an impact mechanism connected to the sensor and having a striker positioned for delivering a blow to the excessively thick article for shifting the same into an eccentric position on and with respect to the first conveyor. The impact mechanism further has an actuating arrangement operating the striker upon receipt of a signal of response from the sensor. The apparatus also has a second conveyor formed of two parallel narrow conveyor belts extending from a discharge end of the first conveyor. The distance between the conveyor belts is less than the length of the articles. There is further provided an arrangement for transferring the articles from the discharge end of the first conveyor onto the second conveyor for effecting further conveyance of the medially arranged articles by the second conveyor by a stable engagement of the medially arranged articles with both conveyor belts and for effecting a dropout of the eccentrically arranged articles by an unstable engagement of the eccentrically arranged articles with the second conveyor.
