Prior art documents disclose a scanner for measuring the volume (empty volume) of empty space of a packaging box to be transported along a packaging line for each packaging line.

By the way, the empty volume scanner disclosed in the prior art document has at least three independent individual sensors for measuring the empty volume of the container, namely a relative height sensor, such as a container height sensor, a container width sensor, and a contour sensor, There are many kinds of sensors, and there are many characteristics to be measured, so that not only the operation software becomes complicated but also the configuration of the entire apparatus becomes complicated, and accordingly, the construction cost of equipment is high.

The prior art reference discloses a cushioning material dispensing apparatus for filling a cushioning material with an empty volume inside a packaging box.

However, since the cushioning material distribution apparatus disclosed in the prior art document is provided for each packaging line, there is a disadvantage that the entire size of the packaging facility becomes large.

As a result, there is a great difficulty in quickly and accurately supplying the cushioning material filled in the empty space of the packaging box with a simple structure.
