Abstract
On a conveyor belt, an ejection mechanism ejects objects travelling thereon which do not fulfill predetermined requirements as detected by a detecting device. To speed up the return of the ejection mechanism to its home position, the ejection cycle is divided into several movements. First a striking element is propelled against the object to be ejected, then the striking mechanism pivots on a fixed point to bring the striking element out of the path of the objects. Next the striking element is retracted and the ejection mechanism pivots back to its original position. A locking device may be used to retain the ejection mechanism in the deflected position to ensure that the striking element is completely retracted before the ejection mechanism pivots back to the home position.
