摘要:
A conveying device for conveying eggs comprises an endless conveyor provided with rollers extending transversely to the direction of conveyance. The rollers are arranged in pairs, and each pair of rollers forms an receiving space, in which an egg is accommodated in such a way that the egg rests on both rollers. The conveying device furthermore comprises a transfer device provided with a plurality of pick-up elements for picking up the eggs from a tray and placing the eggs on the conveyor. The pick-up elements on the transfer device can be moved from a first position in which they are positioned at a distance from each other corresponding to the distance between the individual eggs on the tray, viewed in the direction of conveyance, and a second position corresponding to the centre-to-centre distance between two receiving spaces. In use, the rollers are set in rotation, with the result that an egg resting on them is set in rotation, which is advantageous if the eggs on the conveyor have to be inspected for cracks. In this case by means of a plurality of lasers disposed in a stationary position one after the other a laser beam is directed at the egg during movement of the egg, and the light transmission of the egg surface is observed by optical observation means. Data processing means are equipped to decide on the basis of the observed light transmission whether or not an egg has a crack.
