Patent ID: 7997576

Claim:
Equipment for processing banknotes in stack including a transport mechanism for individually transporting banknotes or similar sheets, and a receiving section for receiving, in superimposition, transported banknotes or sheets, wherein the banknotes or sheets are transported at a given transport velocity (Vt) and the receiving section is arranged downstream of an output section of the transport mechanism, said equipment including transport sensing elements, and further comprising: an interface mechanism with nipping members interposed between said section of the transport mechanism and the receiving section; and at least one electronic control circuit operative on the interface mechanism for causing the nipping members to slow down the banknotes or sheets at the input of the receiving section making easy a regular stacking of the banknotes or sheets; the nipping members being engageable with the banknotes or sheets outgoing from the said section of the transport mechanism for the transport of the banknotes or sheets at a velocity (Vb, Vr) reduced with respect to the given transport velocity (Vt); and the at least one electronic circuit controlling the interface mechanism in response to the information of transit of the banknotes or sheets; wherein an extraction mechanism is actuatable in a stacking step to push a pre-defined portion of the slowed down banknotes toward banknotes or sheets stacked in said receiving section and in which the electronic circuits control the extraction mechanism to engage, as pre-defined portion, a terminal area of the banknotes adjacent to respective trailing edge thereof; a sensing element arranged downstream of the nipping member and adjacent thereto and wherein said at least one electronic circuit responds to signals of the sensing element associated with the transit of the trailing of the banknote or sheet to synchronize the extraction mechanism with the transit of said trailing edges; and a wall defining an output window for the banknotes or sheets to be stacked, wherein said window is adjacent to the said nipping members and wherein said extraction mechanism comprises a shovel lever actuatable for cooperating with the pre-defined portion of the banknote or sheet in stacking, said shovel lever having a terminal section adjacent to said window to cooperate with the terminal area of the banknote in stacking.
