  • Said manipulator unit 30 picks up the trays 69 with the bags 16 on top and by moving away from said rack 70 positions itself at said marking system 31b, see Figs. 17, 18a, 18b.
  • Said marking system 3 lb is movable along a guide 76 so as to label each of the bags 16 by laser.
  • Said marking system 31b can print on each of the bags 16 for example the treatment date and a recognition code.
  • Said manipulator unit 30 can provide a motor for rotating the tray 69 in the direction R3, so that the labelled bags 16 can pass on said chute 29 and subsequently to said storage system 26.
  • said manipulator unit 30 lifts the tray 69 again and positions it, empty, back in said rack 70.
  • Said packaging system 13b is automatic, therefore the medical instruments 50 coming from the disinfection system 12 are automatically bagged by the machine 10 and transferred to said sterilization system 15 by means of said manipulator unit 30.
  • a packaging system 81 of the manual type see Fig. 6.
  • Said packaging system 81 provides one or more bagging film reels 71.
  • the medical instruments 50 exiting the disinfection system 12 are bagged by an operator and introduced into the sterilization system 15.
  • the machine 10a, 10b is provided with a display 66, shown exemplarily for the machine 10b in Fig. 5, to allow the user to follow the treatment operations.
  • Said display 66 is connected to a control unit that regulates and synchronizes the operation of the various components of the machine 10a, 10b.
