EFFECT OF STACK HEIGHT ON HIGH-SPEED ORIENTATION AND STACKING OF PARTS BASED ON INTERNAL FEATURES

摘要

Orientation and stacking of parts has largely been based on their external features. There are a number of parts that need to be oriented and stacked based on their internal features, either because internal features are of primary importance or because of a lack of appropriate external features. In this work, we study the problem of stack stability during orientation and stacking of parts with internal features as applied to our earlier proposed methodologies. An analytical model of the problem is derived and experiments are performed to verify this model. The results show that the stability of a (tack increases as the height of stack increases and that the location of internal features, which determine the location of the capturing guides, is also important.
