Abstract
A box inspector for detecting at an inspection station an unacceptable skew in, an item missing from, and/or an unacceptable gap in a box. The box inspector has pairs of aligned emitters and receivers generating a signal when an unacceptable skew is detected, at least two item present sensors corresponding to the number of items adapted to be located in a single row within the box and generating an item absent signal when an item is missing from the box, a gap detect sensor generating an unacceptable gap signal when the gap is larger than a predetermined gap size, and a box present sensor generating a box present signal when a box arrives at the inspection station. A controller receives signals from these components and generates indications when the box is unacceptably skewed, an item is missing from the box, and/or an unacceptable gap exists in the box.
