Control Method for Banknote Accumulation Device, and Device and Cash Processing Apparatus

A control device for a banknote accumulation device, the banknote accumulation device comprising a receiving cavity, a banknote conveying mechanism and a support plate driving mechanism, wherein the receiving cavity comprises a first opening, the first opening is configured to receive a banknote to be accumulated into the receiving cavity, a support plate is movably disposed in the receiving cavity to support banknotes;

• the banknote conveying mechanism is configured to drive banknotes to pass through the first opening into the receiving cavity so that the banknotes are stacked on the support plate;
• and the support plate driving mechanism is drivingly connected to the support plate and is configured to drive the support plate to move along a direction in which the banknotes are stacked, the control device comprising:
• a determination module configured to determine whether a banknote to enter the receiving cavity is an abnormal banknote, wherein the abnormal banknote is a banknote that meets any one of the following conditions:
• a tilt angle of the banknote exceeds a first preset value, a length of the banknote exceeds a second preset value, the banknote and another banknote are stuck together, the banknote overlaps another banknote, or a spacing between the banknote and an adjacent banknote is smaller than a third preset value;
• an adjustment module configured to, in response to determining that the banknote to enter the receiving cavity is the abnormal banknote, control the support plate to move to increase a height of banknote accumulation space;
• and
• a conveyance module configured to, after the adjustment module controls the support plate to move to increase the height of the banknote accumulation space, control the banknote conveying mechanism to convey the abnormal banknote into the receiving cavity.
