Abstract
A box handling apparatus having particular application in the packaging of semiconductor wafers, includes a box opening assembly which can unlatch a lid from a bottom of the box and separate the lid from the bottom. Arms can grip an article, such as a wafer cassette, in the bottom of the box and lift it out. The cassette can be loaded, or wafers already in the cassette unloaded. The apparatus can replace the loaded cassette in the bottom of the box and latchingly re-engage the lid.
