System for the safe coupling of a re-usable bag to a banknote handling and storing machine and relevant use method

A system for the safe coupling of a re-usable bag to a banknote handling and storing machine, the system comprising:

• a bag container, comprised of an upper rigid mouth, of a flexible bag permanently fixed to said rigid mouth and of a lid for closing said rigid mouth;
• and
• a bag-holding frame, suitable for being stably fixed to a safe structure of the machine, for supporting and hooking the bag container when placed inside the machine to be filled in with the banknotes;
• wherein the system further comprises coupling and hooking electromechanical means disposed between the bag container and the bag-holding frame, said coupling and hooking electromechanical means comprising an electro-actuated lock provided on the bag-holding frame and a blocking element provided on the bag container in correspondence of said electro-actuated lock to engage and block into said electro-actuated lock when the bag container is correctly coupled to the bag-holding frame, with a micro-switch associated with said electro-actuated lock to detect the presence and the correct insertion and blocking of the bag container in the bag-holding frame and to send to a control unit a signal of presence and correct blocking of the bag container on the bag-holding frame, said coupling and hooking electromechanical means further comprising a first electric connector provided on the bag-holding frame and a second electric connector provided on the bag container in correspondence of said first electric connector to realize the electrical connection between the bag container, the bag-holding frame and the control unit when the bag container is positioned on the bag-holding frame, and further wherein the lid for closing said rigid mouth is provided with a movable means, movable on command between an opening position and a closing position, suitable to allow, on command, the banknotes passing from the machine to the bag through the closed lid when the bag container is correctly inserted inside the machine.
