  • a recognition step also occurs, in which the recognition means 88 recognize the recognition element 14 associated with that determinate first container 12A and transmit an electrical signal to the control unit 18 comprising the information contained in the recognition element 14 and temporal information relating to the instant in which the container 12 was positioned on the first movement member 62.
  • the method provides a first feed step in which the instruments 11 to be washed are made to advance along the feed line LI and the second empty containers 12B are made to advance along the pick-up line L2.
  • the advance of the instruments 11 to be washed and of the second containers 12B along the feed line LI and the pick-up line L2, respectively, is commanded by the central control unit 18 which in turn commands the movement members 62, 65.
  • the advance can be stepwise or continuous.
  • the second containers 12B are moved independently along the guide 76 of the second movement member 65.
  • the method also provides a stop step in which the first movement member 62 is stopped, so that a group of instruments 11 to be washed is in the proximity of one of the washing units 15.
  • stop step also provides to stop the second movement member 65 so that a second empty container 12B is in the proximity of one of the washing units 15.
  • a pick-up step in which a first container 12A containing the instruments 11 to be washed is automatically picked up by the first movement member 62 and positioned on the first support 67 associated with the washing unit 15.
  • the pick-up step also provides to automatically pick up a second empty container 12B from the second movement member 65 and position it on the second support 71 associated with the washing unit 15.
  • the method provides a recognition step in which the instruments 11 to be washed are located below in the recognition station 30.
  • the recognition step provides to recognize the instruments 11 and transmit an electrical signal to the local control unit 22 encoding the relative position between the manipulation means 19 and the instruments 11 to be washed.
  • the method provides a detection step in which one of the instruments 1 1 to be washed is taken into the detection station 45 by the manipulation means 19 in order to detect any organic traces present on the instrument 11 and determine the relative position of the organic traces with respect to a reference point of the manipulation means 19.
  • the method provides a washing step in which the manipulation means 19 take the instrument 11 into the washing station 55 and the washing device 57 is activated.
  • the instrument 11 to be washed is positioned with respect to the washing device 57 in such a way as to expose to the latter the organic traces present on the instrument 11.
  • the method provides a release step in which the manipulation means 19 release the washed instrument 11 into the second empty container 12B disposed on the second movement member 65.
  • the method provides a manipulation step in which the manipulation means 19 take the instrument 11 inside the manipulation station 35 in order to modify its attitude, so as to facilitate the subsequent steps of detecting traces of dirt on the instrument 11 and washing.
  • the method provides a pick-up step in which the second container 12B is made to advance along the pick-up line L2 and is taken toward the second extraction zone 93 of the outlet station 90 from which it is extracted, manually or automatically, and positioned on the mobile support member 99.
  • the mobile support member 99 will subsequently be used to take a plurality of containers 12 toward a thermal disinfection machine 201 disposed downstream of the apparatus 10, for example as in the plant 200 (fig. 9) according to the present invention.
