摘要

The machine has a rack with a scanner for identification of removal of a batch of empty cylinders. The rack fits perfectly in a fleet existing with a shopkeeper. The scanner has eight brushes, each identifying an empty cylinder to be replaced by a client using a trade mark and storing the empty cylinder in the rack. The identification allows a worker to find the empty cylinder, while a client removes the empty cylinder batch.
